    15/21 hinge part 64a. By closing this battery storage cover 64, the interior of the battery storage part 63 and batteries B1 and B2 can be waterproof and dustproof.
    As shown in Figure 18, when battery storage cover 64 is opened and batteries B1 and B2 are caused to slide to the front with both locking buttons B lowered using fingertips, it is possible to separate the batteries B1 and B2 of the battery storage part 63. An 18-volt lithium-ion battery is used as the B1 battery and a 14.4-volt lithium-ion battery is used as the B2 battery, as well as the second and in the fourth modalities. These batteries can be used as the power source for an electrical mechanical tool 1 (electric planer) or other tools such as an electric drill etc. By charging with a separately prepared charger, batteries B1 and B2 can be used repeatedly.
    In the first to sixth modes above, an AC power supply is not used as the power supply for the electrical appliance 10, 20, 30, 40, 50 and 60, and a rechargeable battery B1, B2 is used instead. The B1 battery is an 18-volt lithium-ion battery that is also used as the power source for the rechargeable electrical mechanical tool 1 (electric planer) and can be separated from the battery clamping part 3 of the same. In addition, battery B2 is a 14.4 volt lithium ion battery, which is also used as the power source for rechargeable electrical mechanical tools such as an electric drill and screwdriver, etc.
    According to the modalities described above, when using the rechargeable electric mechanical tool 1 as an electric planer or hedge cutter on a construction site or a horticultural work place in a park or the like, where it is, Preferably, difficult to obtain an AC power supply, battery 131 (B2) can be temporarily separated from the battery fixing part 3 of the power tool 1 and fixed to the battery storage part 15, 25. 33, 43, 53 and 63. Regarding
    16/21 to that, it is possible to use the electrical appliance 10, 20, 30, 40, 50 and 60 as a coffee maker, an electric kettle or the like in such a situation. As in the case of power tool 1, battery B1, B2 can be used repeatedly by recharging by a charger.
    In the following, a heater control circuit 70 will be described, which can be applied to both electrical apparatus 10 and 20 according to the first and second embodiments. In relation to this heater control circuit 70, it will be described as applied to the electrical appliance 20 of the second modality (a * coffee maker). By a heater 71, the water stored in the main body part of the apparatus 21 is heated and, at the same time, the heat retention plate 23 is heated.
    Figure 19 is a block diagram showing the heater control circuit 70. The heater 71 provided in the electrical appliance 20 can be temperature controlled by the control circuit 70. Batteries B1 and B2 attached to the battery storage part 25 are electrically connected to control circuit 70.
    When battery B1 and / or B2 is attached to battery storage part 25, power is supplied to a voltage regulator 74 by F1, F2 and a diode D1, D2. As a result, a fixed voltage can be applied to a CPU 75, which causes CPU 75 to operate. In this case, 5 volts are supplied to CPU 75 from voltage regulator 74.
    The voltages of batteries B1 and B2 are respectively detected by voltage detection elements 72 and 73. The detected voltages of batteries B1 and B2 are inserted in CPU 75.
    When CPU 75 detects signals that show batteries B1 and B2 are attached and also detects water being boiled by a water level sensor 79, CPU 75 closes a switch SW1 or SW2. In general, SW1 and SW2 switching are electronic changes such as field effect transistors (FET) or mechanical switching such as relays. After a SW3 switch is closed and power is supplied to the
    17/21 boiling 71. An electronic switch as a field effect transistor can be used as the SW3 switch. CPU 75 controls a switching on / off of switch SW3 based on the voltage data detected by the voltage sensing elements 72, 73 and also based on the boiling heater's rated voltage 71. For example, when the rated heater voltage of boiling point 71 is 14.4 volts and the battery voltage B1 is 18 volts, a ratio of a closing time to a switching opening time SW3 is defined as follows.
    (SW switching closing time;) :( SW3 switching opening time) = 1
    In this way, an average voltage applied to the boiling heater 71 can be defined as 14.4 volts, which can suppress energy consumption and prevent damage from the boiling heater 71.
    Similarly, in a case where a nominal voltage of the boiling heater 71 is 14.4 volts and the voltage of battery B1 is 14.4 volts, the SW switch is defined as being constantly on, which can use the heater boiling point 71 without damage. Although energy is supplied to the boiling heater 71, an indicator lamp 76 is kept on, which indicates that the water is being heated.
    Due to this method, the battery that can be used in the first and second modes can have a voltage level as long as the battery can be physically connected. For example, through the use of a high voltage battery such as a 36 volt battery, it is possible to increase the amount of water to be boiled and to increase the heat retention time, thus making it possible to increase the added value of electrical appliances 10 and 20.
    In Figure 6, an 18-volt battery is used on the battery clamp 25a and a 14.4-volt battery is used on the battery clamp 25b. However, the above construction may not be limited by the example described above. Through the use of this method, a user can use the device
    18/21 without having to be especially aware of a position where the battery is inserted.
    A heater temperature sensor 77 detects the temperature of the water stored in the main body part of the device 21. The water temperature sensor 77 detects a boiled water temperature, and the detected water temperature is inserted into CPU 75. The water vaporized by boiling, it is subsequently cooled and then drips into the filter case 24. The steam cooled in this way drips into the coffee powder placed in the filter case 24, through which the coffee is extracted into the decanter 22.
    When there is no water to be detected by a water level sensor 79, CPU 75 turns off the power supply to the boiling heater 71. That is, switch SW3 is open. In addition, as in the case of the boiling heater 71, a SW4 switch is turned on and off so that adequate energy can be exterminated for a heat retention heater 80, when the voltage of battery B1 that is used becomes less than one predetermined value during power supply to the boiling heater 71 or the heat retaining heater 80, switch SW1 is forced to open and then switch SW2 is closed. This will ensure that energy can be continuously supplied to the boiling heater 71 or heat retention heater 80. As a result, boiling water or heat retention can continue for a long period of time without special operation by a user. In this way, it is possible to increase the added value of electrical appliances 10 and 20:
    In the following, a heater control circuit 90 that can be applied to any of the electrical apparatus 30, 40, 50 and 60 according to the third to sixth modalities will be described. Figure 20 is a block diagram showing heater control circuit 90. In relation to heater control circuit 90, it will be described applied to electrical appliance 40 (electric kettle) according to the fourth modality. In the case of the heater control circuit 70 described above for the coffee maker, both the
    19/21 boiling heater 71 and heat retaining heater 80 are provided. However, in the case of the heat control circuit 90 for the electric kettle, the heat retention heater 80 is not used, and only the boiling heater 71 is provided. Except for the construction above, this has the same construction as that of the heater control circuit 70 shown in Figure 19, and thus the same elements are indicated by the same reference numbers and their explanation will be omitted. In addition, each step that is performed up to the step in which the water is boiled is the same as in the case of the heater control circuit 70 and, therefore, the explanations of the same will be omitted. A water temperature sensor 77 detects the temperature of the water stored in the main body part of the device 41. The water temperature sensor 77 detects a boiling water temperature, and the detected water temperature is inserted in the CPU 75. After that , CPU 75 additionally shortens the on-off period in switching on / off control SW3, and reduces the boiler heater's power supply 7 1 to be suitable for heat retention, which can substantially suppress the consumption of energy and keep the heat in the boiled water. As a result, heat retention can be done automatically, and the boiled water can be kept at an appropriate temperature for a long period of time without a user having to operate in particular, which can add value to the electrical appliance 30, 40 , 50 and 60.
    Additionally in the above modalities, by closing the battery storage part 15, 25, 33, 43, 53 and 63 using the battery storage cover 16, 2, 34, 44, 54 and 64, the storage part of battery 15, 25, 33, 43, 53 and 63 can be waterproof and dustproof, and the battery of the electrical appliance 10, 20, 30, 40, 50 and 60 can be protected from storms in various locations construction. Additionally, the devices can be used even in dusty environments without worry.
    20/21
    Modifications can be made in the modalities described above. In the above embodiments, a coffee maker or an electric kettle is shown as examples that use batteries as the power source that can also be used in electrical mechanical tools. However, the present invention is also applicable to several other electrical appliances such as an electric jar that has a heat retention function, an electric stove, an electric heater, an electric jacket heater, an electric hot water bottle, a foot warmer electric and an electric pocket heater, etc.
    In addition, through the operation of a heat exchanger using the energy supplied from battery B1, B2, it is possible to supply a small refrigerator with battery. In a battery-powered refrigerator that does not require an AC power source, the batteries of a rechargeable type electrical power tool can be used as the power source in an outdoor outdoor construction site, and it is possible to provide the worker with cold drinks during homes.
    In the modalities described above, the 18 volt B1 battery and the 14.4 volt 132 battery can be used. However, it is also possible to use the batteries in a mutually interchanged state, that is, to use a 14.4 volt B1 battery and an 18 volt B2 battery. In addition, it is also possible to use two 18 volt B1 batteries and two 14.4 volt B2 batteries.
    In addition, it is also possible to use the electrical appliance in a state where the 18 volt B1 battery (or the 14.4 volt B2 battery) is attached to only one battery attachment part 25a (25b) and no battery is attached the other battery securing part 25b (25a).
    Additionally, the battery voltage of the power tool to be used as the power supply is not restricted to 14.4 volts or 18 volts, and batteries with a different nominal voltage can be used, such as 7.2 volts, 10.8 volts and 36 volt batteries. Additionally, the battery is not restricted to a lithium ion battery and other types of battery such as a nickel-cadmium (Ni-Cd) battery, etc., can be used.
    21/21
    Additionally, in the embodiments described above, sliding-mount batteries are shown as an example, but insertion-type batteries can be used in the present invention.
    Additionally, in the modalities described above, an electric planer is shown as an example. However, it is also possible that other electrical mechanical tools with a rechargeable battery such as an electric drill to drill, an electric screwdriver for screwing or a circular bench saw machine, etc. can be used and the batteries (battery packs) of these power tools can be used as the power source for electrical appliances. Accordingly, it is possible to use an electrical appliance such as a coffee maker or an electric kettle in an external construction site where there is no AC power supply available, and to effectively use auxiliary batteries for power tools.
    In addition, it is also possible to adopt a dual system in which both the batteries of the power tool and a common AC power supply can be used as the power supply for electrical appliances.
