It is designed to circulate to the bath water heat exchanger and the hot water supply heat exchanger. For this reason, the present invention provides a heat exchanger for bath water, a heat exchanger for hot water supply, and a dehumidifying dryer including a condenser and an evaporator that do not use refrigerant. : A switching means is provided in the refrigerant circuit, which is connected to a compressor for converting into high-pressure gas through a refrigerant circuit, and switches the refrigerant between the bath water heat exchanger, the hot water supply heat exchanger, and the dehumidifying dryer. It is characterized by

〔Example〕

The present invention will be described in detail below based on illustrative embodiments.

FIG. 1 is a circuit diagram showing an embodiment of the present invention.

A heat pump 1, a hot water supply tank 2, a circulation tank 4 connected to a bathtub 3, and a dehumidifying dryer 5 are connected by a refrigerant circuit 6. The heat pump 1 includes a compressor 7 that compresses refrigerant to produce high-temperature, high-pressure gas, a heat exchanger 8 that absorbs latent heat of outdoor air, and a capillary tube 9 that reduces the pressure of the refrigerant gas and produces low-temperature, low-pressure gas. A set of these is housed in a frame and installed outdoors.

Said hot water tank 2. A circulation tank 4 and a dehumidifying dryer 5 are connected to the compressor 7 of the 7-tooth pump 1 to circulate the refrigerant. A hot water heat exchanger 10 wound in a coil shape is provided in the hot water tank 2, and the refrigerant is transferred to the hot water heat exchanger 10.
The water inside the tank 2 is heated and supplies water to indoor water supply, showers, etc. The dehumidifying dryer 5 is composed of a condenser 11 provided on the upstream side of the refrigerant circuit 6, an evaporator 13 provided on the downstream side, and a capillary tube 12 provided between these, and has a high IQ. The heat of the high-pressure cold L"1t is radiated by the condenser 11, and the heat is absorbed by the evaporator 13.

Therefore, the evaporator 13 condenses and dehumidifies the indoor warm air, and the condenser 13 warms the indoor air.

This dehumidifying dryer 5 can be a conventionally known one, and is installed in a room such as a dressing room or a bathroom, for example. This makes it possible to dehumidify and dry the rooms, and also to use these rooms as clothes drying rooms. Note that a drain 14 is attached to the evaporator 13 to remove condensed water droplets.

The circulation tank 4 is connected to the bathtub 3 by pipes 15 and 16, so that bath water is circulated between the circulation tank 4 and the bathtub 3. In this circulation tank 4, a filter device 17 for filtering the bath water, a bongo 18, and an activator 19 filled with activated stones such as maifan stone and sulfur stone are connected in series. An ozone generator 20 is also provided, and an air line 21 from the ozone generator 20 is connected to the return line 16 of said line. The circulation tank 4 as shown in Otsu passes the bath water through a filter device 17, dissolves bathing effect substances such as iron, magenium, and calcium in an activator 19, and then passes the bath water through an ozone generator 20. Ozone sterilizes bath water and decomposes fats and harmful components. Therefore,
Water resources can be conserved because the bath water can be recycled for long periods of time due to its purification technology. A bath water heat exchanger 22 connected to the refrigerant 6 is provided in the activator 19 of the circulating lq tank 4 to heat the bath water. In this case, this heat exchange 1a22 is carried out within the mouth filter 17 or between the mouth filter 17 and the pump]8 and the activator 19.
It is also possible to provide a connecting line in the conduit.

Heat exchanger 22 for bath water as described above. Heat exchanger 10 for hot water supply

In this embodiment, this switching means is connected to the compressor 7 and the bath water heat exchanger 2.
2, and a second valve 23 provided between the compressor 7 and the hot water supply heat exchanger 10.
4 and a third valve 25 provided between the compressor 7 and the condenser 11 of the dryer 5. Therefore, by adjusting the opening and closing of these valves 23, 24 + 25, heating of the bath water, heating of the supply (μ), and drying of the bath water are performed. In the figure, 26 and 27 are fans, which assist the heat exchange between the refrigerant and the air, and 28 is a strainer provided in the heat pump 1, which removes moisture and dust from the air. 29 is a check valve.

Next, the operation of this embodiment will be explained. When dehumidifying and drying, the first valve 3 and the second valve 23, 24 are closed, and the third valve 25 is opened. As a result, the high temperature d'S pressure gas from the compressor 7 is supplied into the dehumidifying dryer 5 to dehumidify the room and add products. To heat the bath water in the same way, the second
and close the third valve 24.25 and close the first valve 2
Open 3.

Also, in order to heat the hot water, the first and third valves 23.
This is done by closing the second valve 25 and opening the second valve 24.

Therefore, according to this embodiment, the compressor 7 of the heat pump 1 is used as a driving source to perform dehumidification and drying.

Hot water supply heating and bath γ1. Since heating can be performed, piping and electrical systems can be simplified and construction can be simplified. In addition, a single heat source can be used to perform aeration removal drying, hot water supply heating, and bath drying heating, and the thermal energy of the refrigerant can be used effectively, making it possible to save energy. Furthermore, since the compressor 7 serving as a heat source is installed outdoors, no noise is transmitted indoors.

FIG. 2 (FIG. 2) is a circuit diagram of another embodiment of the present invention, and the same parts as those in the previous embodiment are designated by the same reference numerals.

In this embodiment, a circulation tank is omitted, and a mouth filter 17 and a pump 18 are connected to the bathtub 3, and a heating tank 30 is also connected to the bathtub 3.
is connected. The bath water heat exchanger 19 is the heating tank 3
When the pump 18 is operated, the bath water in the bathtub 3 is circulated between the bathtub 3 and the heating tank 30, and heating is performed. In this embodiment, sterilization of the bath water is not performed, so the number of times of circulation is reduced, but the device is simplified and maintenance is easy.

Note that the present invention can be modified in various ways. A three-way valve may be used as the switching means, and the switching of these valves may be automatically controlled by a controller, which facilitates operation since switching is performed automatically. Furthermore, the bath water heat exchanger may be directly immersed in the bathtub, which further simplifies the device.

〔Effect of the invention〕

As described above, according to the present invention, since the dehumidifying dryer, the supply heat exchanger, and the hot water heat exchanger are connected to the compressor through the refrigerant circuit, thermal energy from a single heat source is effectively utilized. Dehumidifies, dries, and heats hot water.

The person who heats the bath water should be able to do it.
