    Hot water saving shower tray, which prevents waste water from leaving the house without having transferred part of its heat to cold water. The shower tray (1) is placed on a channel box (2), which has a copper tube (3) inside it. The channel box (2) and the copper tube (3) function as a reverse flow tubular exchanger. The residual water of the shower that is hot and dirty, comes into contact with the copper tube (3), which absorbs its heat and transfers it to the cold water of the network that circulates inside it. In this way it is intended to reduce the consumption of hot water. (Machine-translation by Google Translate, not legally binding)

    DESCRIPTION

    Hot water saving shower tray.

    Technical sector 5

    The invention is part of the renewable energy sector.

    It is intended, through a shower tray, to achieve a lower consumption of hot water and with it an energy and economic saving. 10

    Background of the invention

    In the world market there are different equipment that allow energy and economic savings when taking a shower. fifteen

    Solar hot water panels are commonly known.

    Solar panels for hot water are an excellent option in parallel close to the equator, however in latitudes far from the equator the contribution of solar radiation is less and its efficiency decreases.

    In addition, the installation of solar hot water panels can be combined with other equipment. These equipments recover the heat from the sewage of showers through a heat exchange to the cold network water. 25

    These heat exchange equipment are placed under the bathtub, in the drain pipe. They are small-sized equipment, where heat exchange can be improved by increasing the size of the exchange area and decreasing the speed of wastewater as it passes through the equipment. 30

    In addition, there are also equipment that stores the wastewater in the bathtub or shower in a tank and transfers the heat to a network cold water accumulator by means of a compressor and a gas, such as refrigeration equipment.
     35
    This invention aims to unify in a shower tray a device which saves hot water and increases the energy savings of other equipment, in addition to having an architectural integration in the bathroom.

    Explanation of the invention 40

    The operation of the invention is to recover the heat from the shower wastewater by means of a tubular exchanger inside the shower tray.

    The goal is energy saving and at the same time economical when the user takes a shower.

    When taking a shower, the hot water is mixed by the user with cold network water to avoid burns.
     fifty
    In solar panel equipment the water reaches temperatures of 70º in order to prevent the legionella and it must be mixed with cold water so that the user can take a shower.

    Dirty water leaves the house with an approximate temperature of 30º, the idea is to recover that heat.

    With the recovered heat, the cold network water is heated, which will then be used by the user to shower. 5

    By increasing the temperature of cold water, the user has a lower consumption of hot water.

    That is, the idea is to recover the heat from the wastewater in the shower and transfer the heat to the cold water that will then be mixed in the shower faucet with the hot water.

    In order to raise the temperature of the cold network water as much as possible, the heat exchange will be carried out in reverse flow.
     fifteen
    The components of the invention are three: a shower tray (1), a duct box (2) and a copper tube (3).

    The channeling box (2) and the copper tube (3) form a tubular exchanger that is located under the shower tray. twenty

    The components of the invention are described below.

    Shower tray (1)
     25
    The shower tray will be made of resin and pour the dirty shower water over the ductwork box (2).

    It will have a flange that will work as a coupling between the shower tray (1) and the canalization box (2). 30

    This tab is called coupling (14).

    Channeling Box (2)
     35
    It will be placed under the shower tray (1), and will support this.

    The channeling box (2) will be constructed of plastic, being able to be made of polybutylene or polyvinylchloride and will provide a channeling of the residual shower water.
     40
    Inside the ductwork box (2) will flow the residual shower water, ie dirty water, from the siphon valve (4) to the drain (6) of the duct box (2).

    Another characteristic of the canalization box (2) is that the drain (6) will be on its side, and saves height to the invention, thus having a better architectural integration in the barium room.

    Copper tube (3)
     fifty
    The copper tube (3) will be responsible for heat exchange. The copper tube (3) will be located inside the pipe box (2).

    The copper tube (3) will be connected to the network cold water pipe (7) and the return pipe (8). Inside the copper tube (3) will flow cold network water.

    Waste water from the shower will flow out of the copper tube (3).

    Preferred Embodiment of the Invention

    The fundamental characteristic of the hot water saving shower tray is that it performs a heat exchange between the residual shower water and the cold network water.
     35
    For the understanding of this patent, wastewater from the shower is considered to be that which is swallowed by the shower drain while the user is showering.

    This wastewater retains its heat in addition to traces of dirt and soap.
     40
    The wastewater is channeled through the siphon valve (4) and will run through the entire canalization box (2) until it reaches the drain (6). Once the drain (6) has passed, the wastewater will continue on its way to the siphoning canister (5) of the bathroom.

    The copper pipe 45 (3) will be placed in the countertop with the waste water that runs through the pipeline (2).

    Cold network water circulates through the copper tube (3), which will then be used by the user to mix it with the hot water and shower.
     fifty
    The cold network water that runs through the copper tube (3) is supplied by the network cold water pipe (7) and once the copper tube (3) is run it is directed to the shower tap (19) by means of the pipe return (8).

    When there is a temperature difference, the copper tube (3) will allow a heat exchange by contact between the cold network water that circulates inside and the residual water that circulates outside, where the cold water will absorb heat from the water residual.

    To maximize the cold water temperature, heat transfer takes place in reverse flow. That is, the fluids move in opposite directions.

    As a result of this process, the temperature of the cold water rises as it passes through the copper tube (3) and the temperature of the waste water decreases as it passes through the duct box (2). 10

    For proper operation, the plumber must make some cuts in the duct box (2) in order to install the mains cold water pipe (7) and the return pipe (8).
     fifteen
    These cuts are reflected in Figure No. 5 as a groove (15) and its function is to allow the passage of the cold water pipe (7) and the return pipe (8).

    Next, the mains cold water pipe (7) must be connected to the copper tube (3) at the junction with the cold water pipe (17). This junction is near the drain (6). twenty

    In addition, the return pipe (8) must be connected to the copper tube (3) at the junction with the return pipe (18). This joint is near the siphon valve (4).

    The connections of the copper tube (3) to the mains cold water pipe (7) and to the 25-line pipe (8) must be done by the plumber and make sure there is no loss of water.

    For a correct connection between the shower tray (1) and the ductwork box (2) the shower tray (1) will have a coupling (14).
     30
    For a better architectural integration, the drain (6) will be on one side of the pipe box (2) and thus saves height to the invention.

    In bathrooms where the drains are hung, the ducting box (2) and the copper tube (3) will be placed under the slab (10) as shown in Figure No. 35.

    If the ductwork box (2) is under the slab (10), it will be fastened with knobs (11) to it.

    The user would mix the hot water and the cold water, where the cold water 40 will have gained a few degrees as it passes through the copper tube (3) and will reduce the consumption of hot water.
