Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sauna, drying, and hot water supply device that can be used for multiple purposes such as sauna, drying, and hot water supply.

[Problems to be solved by conventional technology and ideas] Generally, there are dehumidifiers and water heaters that use a refrigeration cycle, but these are all dedicated machines for dehumidifying and supplying hot water, and they are not used all the time. However, the utilization rate is low.

The present invention was made based on the above points, and its purpose is to create a sauna that can be used for multiple purposes such as sauna, drying, and hot water supply, and that can improve the operating rate of the device. , drying and hot water supply equipment.

[Means for Solving the Problems] That is, the sauna, drying, and hot water supply device according to the present invention includes a compressor, a four-way switching valve, an accumulator, a hot water supply throttle, an air heat exchanger, and a sauna that are connected in sequence to a refrigerant circuit. an outdoor unit consisting of a diaphragm, a solenoid valve connected in parallel with the sauna diaphragm, and a refrigerant circuit connected from the front and back of the air heat exchanger to the inlet of the accumulator via solenoid valves, respectively; A hot water tank is connected to the water heat exchanger via a water pump, a water supply pipe, and a hot water supply pipe, and is arranged in series with a hot water unit connected between the four-way switching valve of the outdoor unit and the hot water supply throttle. and a drying aperture and a solenoid valve connected in parallel between the air heat exchangers, and a sauna connected between the four-way switching valve of the outdoor unit and the sauna aperture. , and a drying unit.

[Function] In other words, a single device can selectively perform sauna operation, drying operation, or hot water supply operation by appropriately controlling the four-way switching valve, the opening and closing of the solenoid valve, the on and off of the blower, and the on and off of the water pump. This is what we are trying to do.

[Effect of the invention] Therefore, it is now possible to selectively perform sauna operation, drying operation, and hot water supply operation with a single device, which replaces the conventional method of using dedicated machines for each with only a single function. This makes it possible to significantly improve the operating rate of the device compared to the conventional method, and the structure is simple, which is extremely effective in reducing manufacturing costs.

[Example] An example of the present invention will be described below with reference to the drawings. The figure is a system diagram showing a schematic configuration of a sauna, dryer, and hot water supply device according to this embodiment. Reference numeral 1 in the figure indicates an indoor unit section (sauna, drying unit), and the sauna, drying, and hot water supply apparatus of this embodiment is this indoor unit section 1.
, an outdoor unit (outdoor unit) 2 and a hot water supply unit (hot water supply unit) 3. Air heat exchangers 4 and 5 are installed in the indoor unit 1, and these air heat exchangers 4 and 5 are connected via a refrigerant pipe 6. The above refrigerant pipe 6
A parallel circuit consisting of a solenoid valve 7 and a drying aperture 8 is inserted. Further, a blower device 9 is installed in the indoor unit section 1 . The air heat exchangers 4 and 5 are connected to the outdoor unit 2 via refrigerant pipes 10 and 11.

A four-way switching valve 12 is connected to the refrigerant pipe 11 of the outdoor unit section 2, a refrigerant pipe 13 is connected to the four-way switching valve 12, and this refrigerant pipe 13 is arranged up to the inside of the water heater section 3. ing. Further, a refrigerant pipe 16 in which a compressor 14 and an accumulator 15 are inserted is connected to the four-way switching valve 12. On the other hand, an air heat exchanger 17 is provided in the refrigerant pipe 10.
is connected to the air heat exchanger 17, and a refrigerant pipe 18 is connected to the air heat exchanger 17. This refrigerant pipe 18
is arranged up to the water heater section 3. A parallel circuit of a solenoid valve 19 and a sauna throttle 20 is inserted into the refrigerant pipe 10 of the outdoor unit section 2 . In addition, the refrigerant pipe 18 of the outdoor unit 2 has a hot water supply throttle 2.
1 is inserted. In addition, the air heat exchanger 17
refrigerant pipe 2 with solenoid valves 22 and 23 inserted therein.
4 are attached. A refrigerant pipe 25 is disposed between the refrigerant pipe 24 between the solenoid valves 22 and 23 and the refrigerant pipe 16. Note that the reference numeral 26 in the figure indicates a blower device.

The above-mentioned refrigerant pipe 13 arranged up to the inside of the water heater section 3
and 18 are connected to the water heat exchanger 31.
This water heat exchanger 31 has water pipes 32A and 32
A hot water tank 33 is connected through B, and water pipes 34A and 34B are connected to this hot water tank 33.
is connected. Further, a water pump 35 is inserted into the water pipe 32A.

The operation will be explained based on the above configuration. First, the case of hot water supply operation will be explained. When performing hot water supply operation, the compressor 14, the water pump 35, and the air blower 26 are in an on state, and the solenoid valve 22 is in an open state. On the other hand, the blower 9 is off and the solenoid valves 7, 19 and 23 are closed. The gas refrigerant compressed by the compressor 14 to a high temperature and high pressure is connected to the refrigerant pipe 16, as shown by the solid arrow in the figure.
It is transferred to the water heat exchanger 31 via the four-way switching valve 12 and the refrigerant pipe 13. In this water heat exchanger 31, the refrigerant is cooled by exchanging heat with water supplied via the water pump 35, and becomes a high-pressure liquid refrigerant. On the other hand, the temperature of the water increases in this case. The high-pressure liquid refrigerant passes through the refrigerant pipe 18 and is reduced in pressure by the hot water supply throttle 21 and flows into the air heat exchanger 17 . This air heat exchanger 17
The refrigerant exchanges heat with the air supplied by the blower 26 and becomes a low-pressure gas refrigerant. This low-pressure gas refrigerant flows into the accumulator 15 via the refrigerant pipe 24, the solenoid valve 22, the refrigerant pipe 25, and the refrigerant pipe 16, and further passes through the refrigerant pipe 16 to the compressor 1.
Return to 4. At this time, the refrigerant pipe 6 of the indoor unit section 1,
10 and 11 and air heat exchangers 4 and 5
The inside is in a low-pressure gas state. The hot water supply operation causes the temperature of the water in the hot water tank 33 to rise, and when the water temperature reaches a predetermined temperature, the hot water supply operation is turned off. The heated water in the hot water tank 33 is used, for example, for taking a bath or washing hands.

Next, the case of sauna operation will be explained. In the case of this sauna operation, the compressor 14, the blower device 9
and 26 are on, and the water pump 35 is off. Moreover, the solenoid valves 7 and 23 are open, and conversely, the solenoid valves 19 and 22 are closed.
The gas refrigerant compressed by the compressor 14 to a high temperature and high pressure is transferred to the refrigerant pipe 1 as shown by the broken line arrow in the figure.
6. It flows into the air heat exchanger 5 via the four-way switching valve 12 and the refrigerant pipe 11. The gaseous refrigerant that has flowed into the air heat exchanger 5 passes through the solenoid valve 7 and the refrigerant pipe 6.
The air is introduced into the air heat exchanger 4 via the air heat exchanger 4. At that time, the refrigerant exchanges heat with the air supplied by the blower 9 and is cooled to become a high-pressure liquid refrigerant. On the other hand, the heated air is transferred to a sauna room (not shown) and used. The liquid refrigerant is introduced into the air heat exchanger 17 via the refrigerant pipe 10 and the sauna throttle 20, where it is heated by air supplied by the blower 26 and becomes a low-pressure gas. This low-pressure gas flows into the accumulator 15 via the refrigerant pipe 24, the electromagnetic valve 23, the refrigerant pipe 25, and the refrigerant pipe 16, and further returns to the compressor 14 via the refrigerant pipe 16. At this time, the refrigerant in the water heater section 3 is in a low-pressure gas state.

Next, the case of dehumidification and drying operation will be explained.
In this case, the compressor 14, blower devices 9, 26
is in the on state, and the water pump 35 is in the off state. Further, solenoid valves 7, 19 and 23 are open, and conversely solenoid valve 22 is closed. This dehumidifying and drying operation is substantially the same as the sauna operation described above, except that the air heat exchanger 4 is used as a dehumidifying coil in order to use the sauna room as a drying room. That is, the refrigerant, which has been cooled by the air supplied by the blower 9 in the air heat exchanger 5 and becomes liquid, is depressurized by the drying aperture 8, as shown by the white arrow in the figure, and then transferred to the air heat exchanger 4. It is heated to become a gaseous refrigerant. At this time, by increasing the capacity of the air heat exchanger 5 compared to that of the air heat exchanger 4, it becomes possible to obtain dehumidified air with a relatively high temperature, and supply it to a drying chamber (not shown) to dry it. I will offer it to you. The gas refrigerant is introduced into the air heat exchanger 17 via the refrigerant pipe 10 and the solenoid valve 19, and after being further heated returns to the compressor 14 through the same route as in the sauna operation.

In addition, these hot water supply operation, sauna operation and dehumidification,
Drying operation can be easily selected by operating a switch (not shown).

According to the sauna, drying, and hot water supply device configured as described above, sauna operation, drying operation, and hot water supply operation can be selectively performed with a single device by simply operating a switch. The operating rate of the device can be significantly improved compared to specialized machines. In particular, a four-way switching valve installed in the refrigerant circuit connecting the outdoor unit, hot water supply unit, and outdoor unit is used to selectively switch the high temperature, high pressure gas refrigerant compressed by the compressor to the hot water supply unit side or the indoor unit side. Since the system enables sauna operation, drying operation, and hot water supply operation, its configuration is simple, and it is possible to obtain extremely significant practical effects such as being able to reduce the manufacturing cost of the equipment.
