    CLIMATE APPLIANCE INCLUDING FLANTS WITH WATER LEADER TECHNICAL TECHNOLOGY The present invention relates to a climate apparatus which performs heating and defrosting. Prior Art A conventional air conditioner is described in patent document 1. This air conditioner includes an indoor apparatus part beldgen indoors and an outdoor apparatus part beldgen outdoors. The outdoor appliance part is equipped with a compressor, an outdoor heat exchanger, and an outdoor fan, while the indoor appliance part is equipped with an indoor heat exchanger and an indoor fan. The compressor causes a refrigerant to flow to perform a cooling cycle. In the indoor heat exchanger and the outdoor heat exchanger, a refrigerant line is mounted with a plurality of flanges close to each other which effect heat exchange with air passing between the flats.
    A part of the compressor provided with an outlet for refrigerant is connected to one end of the indoor heat exchanger and one end of the outdoor heat exchanger via a four-way valve with the aid of the refrigerant line. The other ends of the indoor heat exchanger and the outdoor heat exchanger are connected via an expansion valve using the refrigerant line. The outdoor flange is the bellows opposite the outdoor heat exchanger and causes heat exchange between the outdoor heat exchanger and the outdoor air. The indoor fan carries indoor air into the indoor appliance part and forwards the air, after performing heat exchange with the indoor heat exchanger, into a room.
    During heating, by switching the four-way valve, the outflow of refrigerant from the compressor flows through the indoor heat exchanger, the expansion valve, the outdoor heat exchanger and returns to the compressor. In this way, the indoor heat exchanger forms a high temperature part in the cooling cycle, while the outdoor heat exchanger forms a low temperature part in the cooling cycle. The indoor air reaches a higher temperature through heat exchange with the indoor heat exchanger and is passed into the room, whereby indoor heating is carried out.
    During cooling, the outflow of refrigerant from the compressor flows by switching the four-way valve in a direction opposite to the direction during heating. In other words, the refrigerant flows through the outdoor heat exchanger, the expansion valve, the indoor heat exchanger and returns to the compressor. In this way, the outdoor heat exchanger forms the high temperature part of the cooling cycle, while the indoor heat exchanger forms the low temperature part of the cooling cycle. The indoor air has a lower temperature thanks to heat exchange with the indoor heat exchanger and is passed into the room, whereby cooling is carried out indoors.
    During heating, the outdoor heat exchanger also has frost and defrosting can easily be performed at predetermined intervals. During defrosting, the indoor surface and the outdoor surface are stopped, and the refrigerant flows in the same direction as the direction during cooling thanks to switching of the four-way valve. In this way, the outdoor heat exchanger forms the high temperature part of the cooling cycle, and the frost on the outdoor heat exchanger melts. The defrost water from the melting of the frost flows down the flange and falls below the heat exchanger, making it possible to defrost the outdoor heat exchanger. With the above-mentioned conventional climate apparatus, however, the defrost water, which flows down the flanges in the outdoor heat exchanger during defrosting, is retained between adjacent flanges of the surface tension. In a case where the outdoor appliance part is installed in a cold area with a low outdoor temperature, the retained water on the flanges freezes again if the defrosting is stopped. If heating is carried out in this condition, frost grows on the ice which is again frozen between the flanges and consequently the amount of frost and it becomes necessary to shorten the defrosting intervals. Consequently, there is a problem in that the heating indoors is not carried out to a sufficient extent and the convenience provided by the air conditioner decreases.
    An object of the invention is to provide a climate apparatus capable of providing improved comfort.
    Troubleshooting To achieve the above andamal, the present invention provides an air conditioning apparatus comprising: a compressor driving a cooling cycle; an indoor heat exchanger that performs heat exchange with indoor air; and an outdoor heat exchanger which performs heat exchange with outdoor air, the compressor being crossed to provide heating, the indoor heat exchanger being used as a high temperature part in the cooling cycle and the outdoor heat exchanger being used as a low temperature part, and defrosted by causing a refrigerant to flow in a direction opposite to the direction of heating, wherein in the outdoor heat exchanger a plurality of flanges are fixed to a refrigerant line so that they are close to each other, an air flow passes between the flanges and out heat exchange, and a water conductor part for closing a space between the 3 flanges in one duct in the direction of flow of the air flow is occupied by the lower duct of the outdoor heat exchanger.
    According to this structure, the charging medium flows and the cooling cycle is carried out under heating by grinding the compressor. The outdoor heat exchanger forms the low temperature part of the cooling cycle, and the air, which performs heat exchange with the indoor heat exchanger, which forms the high temperature part of the cooling cycle, is passed into a room, whereby indoor heating is performed. Harvidlag performs the outdoor heat exchanger heat exchange with outdoor air that passes between the flanges. If there is frost on the outdoor heat exchanger, defrost is performed. During defrosting, the refrigerant flows in a direction opposite to the direction during heating, and the outdoor heat exchanger forms the high temperature part of the cooling cycle. Accordingly, the frost on the outdoor heat exchanger melts and the defrost water flows down the flanges. The defrost water that flows down one part of the flanges (eg a part with an outlet for air flow) is led by the water conductor part, which connects a lower duct space between the flanges, to the other part (eg a part with an inlet for air flow). The defrost water led by the water conductor part is combined with defrost water which flows down the other part and falls down below the outdoor heat exchanger.
    The invention is further illustrated by the fact that in the climate apparatus with the structure above, the defrost water, which flows down one part of the flanges in the flow direction of the air flow during heating, is received by the water conductor part and led to the other part.
    The invention is further illustrated by the fact that in the climate apparatus with the structure above, the water conductor part is obtained by bending a corner part which includes a lower surface of the flanges. According to this structure, the defrost water flowing down one end of the flanges is led to the other part of the water conductor part obtained by bending the corner part of the lower end of the flange.
    The invention is further illustrated by the fact that in the climate apparatus with the structure above a plurality of rows of refrigerant lines are arranged in a zigzag pattern in the flow direction of the air flow, and a lower end of the refrigerant line which is coated in one part in the flow direction of the air flow is coated. the lower spirit of the refrigerant line coated in the second portion. According to this structure, the refrigerant lines are arranged so that they are parallel to each other in the direction of flow of the air flow through the flanges, and the water conductor part is arranged on the flange where the distance from the lower end of the flange to the refrigerant line is longest.
    The invention is further characterized by the fact that in the climate apparatus with the structure above, in the outdoor heat exchanger, the water conductor part is located on one side downstream in the flow direction of the air flow during heating. According to this structure, during heating outdoor air performs heat exchange with the refrigerant line and the flanges in the outdoor heat exchanger. Harvidlag collides the air that flows between the flanges in a lower part with the water conductor part coated in the part is tightened and flows upwards.
    The invention is further illustrated by the fact that in the climate apparatus with the structure above, the refrigerant line, which is coated in the high-temperature part of the cooling cycle during heating, is coated under the outdoor heat exchanger. According to this structure, the refrigerant line coated under the outdoor heat exchanger forms the high temperature part of the cooling cycle during heating and frost on a lower part of the outdoor heat exchanger and on the bottom wall of the outdoor appliance part is mitigated.
    Advantageous effects of the invention According to the invention, the water conductor part, which closes the space between the flanges in one duct in the direction of flow of the air flow, is coated in the lower duct of the outdoor heat exchanger. Thus, it is possible that the defrost water, which flows down one part of the flange during heating, is received by the water conductor part so that the defrost water is easily led to the other part. As a result, the defrost water flowing down one portion of the flange combines with defrost water flowing down the other portion and falls neatly. Due to this, the amount of river increases defrost water per unit area which is led to the lower spirit of the flange and falls down rapidly from the lower spirit of the flange. This makes it possible to reduce the amount of defrost water retained by the lower spirit of the flange due to surface tension and reduce the amount of frost on the outdoor heat exchangers. Consequently, it is possible to extend the intervals between defrosting and to improve the convenience provided by the air conditioner.

    Description of embodiments In the following, embodiments of the invention are described with reference to the drawings. Fig. 1 is a circuit diagram showing a cooling cycle for a climate apparatus according to a first embodiment. The air conditioner 1 has an indoor appliance part 10 coated indoors and an outdoor appliance part 20 coated outdoors. In the climate apparatus 1, a compressor 21 is beldgen in the outdoor apparatus part 20, which compressor causes a refrigerant to flow in a refrigerant line 2 and drives the cooling cycle.
    The outdoor appliance part 20 includes: a four-way valve 22 connected to the compressor 21; an outdoor heat exchanger 23; an expansion valve 24; and an outdoor fan 25. In the indoor appliance part 10 there are: an indoor heat exchanger 13; and an indoor heat exchanger 15. In the indoor heat exchanger 13 and the outdoor heat exchanger 23, a plurality of fins 30 (see Fig. 5) are fixed to the refrigerant line 2 so that they are close to each other, and perform heat billing with air passing between the fins 30.
    The compressor 21 is connected to one end of the outdoor heat exchanger 23 and one end of the indoor heat exchanger 13 via the four-way valve 22 by means of the refrigerant line 2. The other ends of the outdoor heat exchanger 23 and the indoor heat exchanger 13 are connected via the expansion valve 26 to the heat line the beldgen in a lower part of the outdoor heat exchanger 23 also consists of the refrigerant line 2 between the expansion valve 24 and the indoor water exchanger 13.
    The outdoor surface 25 is the bellows opposite the outdoor heat exchanger 23. By entering the outdoor heat 25, outdoor air is supplied to the outdoor heat exchanger 23 and heat exchange between the outdoor heat exchanger 23 and outdoor air is promoted. The air which performs the heat exchange with the outdoor heat exchanger 23 is discharged outdoors via an air outlet (not shown) which is accustomed to the outdoor housing surface 25 and opens out from the outdoor appliance part 20.
    The indoor surface 15 and the indoor heat exchanger 13 are formed in an air flow chamber (not shown) formed in the indoor apparatus part 10. By driving the indoor surface 15, indoor air flows into the air source carriage and is then supplied to the indoor heat exchanger 13, and heat exchange is carried out between the air and air heaters. the indoor heat exchanger 13. The air which provides the heat exchange with the indoor heat exchanger 13 is carried further into a room via an air outlet (not shown) which opens out from the indoor appliance part 10.
    Fig. 2 is a perspective view showing the inside of the outdoor apparatus part 20 of the climate apparatus 1. Furthermore, Fig. 3 is an exploded view of a main part of the outdoor apparatus part 20. In the outdoor apparatus part 20, the compressor 21 is bellows on one end of the bottom plate 29, which has a substantially rectangular shape. seen from above, and which has its short extension in the direction front-back, and which has its long extension in the direction right-left. The outdoor heat exchanger 23 is formed in a substantially L-shape seen from above and is placed upright on a side part opposite the compressor 21 and a rear part of the outdoor appliance part 20. Furthermore, the heating line 26 is located in the lower part of the outdoor heat exchanger 23. A water drainage hall 29a is provided by a several positions on the base plate 29 below the outdoor heat exchanger 23.
    The outdoor fan 25 includes a shaft bellows in the front-back direction and is located opposite the outdoor heat exchanger 23. By cornering the outdoor fan 25, outdoor air flows substantially from a rear of the outdoor appliance part 20 to a front as shown by the arrow B, and exits the heat exchanger with.
    Meanwhile, some of the air flows into the outdoor appliance part 20 from one side and performs heat exchange via a side part of the outdoor heat exchanger 23 and is led forward.
    Fig. 5 shows a vertical cross-section of the outdoor heat exchanger 23. Fig. 6 further shows a view seen in the direction according to the arrow D in Fig. 5. The outdoor heating heater 23 is provided with, in the 8 front-back direction, two rows of refrigerant lines 2 as in a predetermined vertical rise P bOjs in a loop. The refrigerant lines 2 are placed in the front-to-back direction in, deviating vertically, positions in a zigzag pattern. This makes it possible to force the air flowing as shown by the arrow B to come into contact with the refrigerant lines 2 in the front-to-back direction, and to improve the heat exchange efficiency.
    The refrigerant lines 2 are in the front-back direction each mounted with a fixed rectangular flange 30 extending vertically, and the outdoor heat exchanger 23 is assembled as a flange-and-tube type heat exchanger. The flanges 30 are arranged with a predetermined pitch (e.g. 1.3 mm) so that they are close to each other in a direction in which the refrigerant line 2 extends, and an air flow passes between the flanges 30 as shown by the arrow B. A flange 30a is arranged on the refrigerant line 2 on the side upstream when the air flow passes, while the flange 30b is arranged on the refrigerant line 2 on the side downstream.
    In the climate apparatus with the structure described above, during heating, the indoor surface and the outdoor surface 25 and the four-way valve 22 are connected as shown by the solid lines in the figure. When the compressor 21 is run, the refrigerant flows in this direction in the direction indicated by the arrow A, and the refrigerant, which is compressed by the compressor 21 so that it has a high temperature and high pressure, radiates heat into the indoor heat exchanger 13 and condenses.
    The high temperature refrigerant passes through the heating line 26 and is then caused to expand by the expansion valve 24 so that it has a low temperature and high pressure, and is passed on to the outdoor heat exchanger 23. Frost on the bottom plate 29 and a lower part of the outdoor heat exchanger 23 is reduced by the heat line 26. In particular, the amount of frost on the outdoor appliance part 20 increases when it is water against a cold environment, and consequently the heat pipe 26 is often arranged below the outdoor heat exchanger 23.
    The refrigerant flowing into the outdoor heat exchanger 23 absorbs heat and evaporates so that it converts into a low temperature gaseous refrigerant and is passed on to the compressor 21. In this way the refrigerant is circulated and the cooling cycle is performed. The air which performs the heat exchange with the indoor heat exchanger 13, which forms the high-temperature part of the cooling cycle, is carried out into the room by the indoor surface 15, whereby heating takes place indoors. The air which performs the heat exchange with the outdoor heat exchanger 23, which forms the layer temperature part of the cooling cycle, is discharged outdoors by means of the outdoor space 25.
    During cooling, the indoor surface 15 and the outdoor surface 25 and the four-way valve 22 are connected as shown by the broken lines in the figure. When cornering the compressor 21, on this sieve the refrigerant flows in a direction opposite to the direction indicated by the arrow A, whereby the indoor heat exchanger 13 constitutes the low temperature part in the cooling cycle, while the outdoor heat exchanger 23 constitutes the high temperature part in the cooling cycle. The air which provides the heat exchange with the indoor heat exchanger 13 is carried further into the space by the indoor surface 15, whereby indoor cooling is provided. Furthermore, the air performing the heat exchange with the outdoor heat exchanger 23, which constitutes the high temperature part of the cooling cycle, is discharged outdoors by means of the outdoor space 25.
    Furthermore, the outdoor heat exchanger 23, which forms the layer temperature part of the cooling cycle during heating, has frost and consequently performs defrosting at predetermined intervals. During defrosting, the indoor surface 15 and the outdoor surface 25 are stopped, and the four-way valve 22 is connected as shown by the broken lines in the figure. By this, currents flow through the compressor 21 in the direction opposite to the direction indicated by the arrow A, whereby the indoor heat exchanger 13 constitutes the low temperature part of the cooling cycle, while the outdoor heat exchanger 23 forms the high temperature part of the cooling cycle.
    Due to the fact that the outdoor surface 25 is stopped, the heat exchange between the outdoor heat exchanger 23 and the outdoor air is mitigated, and it is possible to effectively drive the temperature of the outdoor heat exchanger 23. Thanks to the fact that the indoor surface 15 is stopped, it is also possible to prevent tuff with a low temperature from being fed into the room.
    Due to the increase in temperature in the outdoor heat exchanger 23, the frost on the outside 10 of the house heat exchanger 23 melts and flows down the flanges 30.
    The water conductor part 32 is formed by bending a horn part which includes a lower surface of the flange 30b in the outdoor heat exchanger 23. Furthermore, the refrigerant lines 2 are arranged in a zigzag pattern, and the lower part of the refrigerant line 2 which is coated on the side downstream in the flow direction layer which is higher than the lower part of the refrigerant line 2 which is located on the upstream side. As a result, the distance H 2 between the lower spirit of the flange 30b on the side downstream forming the water conductor part 32 and the refrigerant line 2 at its lowest layer is greater than the distance H1 between the lower spirit of the flange 30a on the side upstream and the refrigerant line 2 at its lowest part. Accordingly, it is possible to easily form the water conductor portion 32 by bending the flange 30b.
    The flanges 30b are arranged so that they are parallel to each other in the direction in which the refrigerant line 2 extends, and the distance between adjacent flanges 30b is small. Thanks to this, water conductor parts 32 overlap, obtained by bending 11 adjacent flanges 30b, and close the space between adjacent flanges 30b. The defrost water flowing down the flange 30b in one end portion (side downstream) in the flow direction of the air stream during defrosting is received by the water conductor portion 32 which closes the lower end and is led to the other end portion (side upstream). The defrost water flowing down the flange 30a on the side upstream in the flow direction of the air flow is combined with the defrost water on the side downstream led by the water conductor part 32 and falls. The defrost water falling from the outdoor heat exchanger 23 is drained via the water drainage tail 29a.
    In this case, the amount of river per unit area of defrost water drained from the lower spirit of the flange 30, on a part of which the water conductor part 32 is arranged, is comparable to a case where the water conductor part 32 does not form, and falls rapidly from the lower spirit of the flange 30. Thus, it is possible to reduce the amount of defrost water retained by the lower spirit of the flange 3. On the surface of surface tension In accordance with the present embodiment, the water conductor portion 32, which closes the space between the flanges 30 at one end in the air flow direction, is arranged at the lower end. by the outdoor heat exchanger 23. This makes it possible during defrosting by using the water conductor part 32 that the defrost water flowing down one (flange 30b) of the flanges 30 can be received and that the defrost water can easily be led to the other (flange 30a). As a result, the defrost water flowing down the flange 30b on one side combines with the defrost water flowing down the flange 30a on the other side and falls down.
    Due to this, the amount of river per unit area of defrost water drained from the lower spirit of the flange 30 increases and falls rapidly from the lower spirit of the flange 30. 12 It is thus possible to reduce the amount of defrost water retained by the lower spirit of the flange 30 on the ground. of surface tension and to reduce the amount of frost on the outdoor heat exchanger 23. Consequently, it is possible to extend the intervals for the defrosts and to improve the comfort provided by the air conditioner.
    In addition, it is possible in a simple manner by bending the mandrel comprising the lower surface of the flange 30 to form the water conductor part 32 for conducting defrost water.
    The heating line 26 (refrigerant line 2) which is the bellows in the high temperature part of the cooling cycle during heating is further bellows under the outdoor heat exchanger 23, and consequently it is possible to reduce the amount of frost on the bottom plate in the outdoor heater part and a lower part of the outdoor heat exchanger 23. like for example. a glass tube heater or the like may be provided.
    The plurality of rows of refrigerant conduits 2 are further arranged in a zigzag pattern in the flow direction of the air flow, and the lower end of the refrigerant conduit 2 on the downstream side is the bellows in a height higher than the lower part of the refrigerant conduit 2 on the upstream side and consequently it is possible to simple sail form the water conductor part 32 by bending the flange 30.
    In a manner similar to that described above, the water conductor portion 32 may be arranged on the flange on the side upstream in the flow direction of the air stream during heating. However, if the water conductor portion 32 is arranged on the flange 30 on the side downstream in the air flow direction during heating, the heat exchange surface increases. side upstream in the flow direction of the air flow, and it is possible to improve the heat exchange efficiency. In the present embodiment, a structure can be used according to which, for example, 16dning is applied to the part where the water conductor parts 32 on adjacent flanges 30b overlap to close a gap of the overlapping part. This structure closes the gap which occurs at the overlapping part of the water conductor parts 32, and consequently it becomes easy to direct the defrost water on the side downstream to the side upstream.
    In the embodiment shown, the refrigerant lines 2, which are arranged in parallel with each other in the front and rear parts of the outdoor heat exchanger 23, are mounted with the fixed separate flanges 30a and 30b, although a common flange for the refrigerant lines 2 in the front and rear could also used. In other words, each of the flanges arranged parallel to each other in the direction in which the refrigerant line 2 has its extent can be fixed so that it bridges the refrigerant lines 2 in the front and rear parts.
    In the foregoing, an embodiment of the present invention has been described, however, the scope of the invention is not limited to this embodiment, and it is possible to make various modifications and apply them in practice without departing from the spirit of the invention.
    Industrial Applicability The present invention is applicable to a climate apparatus which performs heating and defrosting.
