Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heat pump device.

[Conventional technology]

A heat pump device pumps up and utilizes heat from the air, and is a highly efficient device that consumes a large amount of energy per unit of power consumed.As shown in Figure 1, heat pump devices have traditionally been equipped with an outdoor unit 24 and an indoor unit 25.
It is used as a room air conditioner, and recently it is used as a second air conditioner.
As shown in the figure, a condenser 17 is connected to an outdoor unit 24 and is being used to heat a bathtub 15.

In addition, conventional air-cooled condenser devices have been designed to take in the cooling air of the air-cooled condenser in the summer or from outside and exhaust the heat outdoors, and in the winter, the cooling air of the air-cooled condenser takes in indoor air and exhausts the heat indoors. (Refer to Japanese Utility Model Application Publication No. 51-124252) A box housing a heat exchanger and two blowers via this heat exchanger is installed by penetrating the partition wall between indoors and outdoors, and By making the opening freely openable and closable, the cooling or heating and ventilation functions can be operated simultaneously or either independently, and in the case of independent operation, the air transport by each blower is independent of the other functions. An air conditioner (see Japanese Utility Model Application Publication No. 53-5372) has been proposed.

[Problem to be solved by the invention]

Among those described in the conventional technology, FIGS. 1 and 2
The equipment shown in the figure has the problem of being an expensive piece of equipment because each has a single function of air conditioning and bath heating, and the operating time is short.

In addition, the structure described in Japanese Utility Model Application Publication No. 51-124252 has a structure in which the compressor and other parts are placed separately from the cover that houses the air-cooled condenser and the blower, which requires a large installation space, and also requires only cooling and heating. It has only one function, and in the summer, it wastes energy because it exhausts heat outside. In addition, Jikko Sho 53-5372
Although the device described in the above publication has a ventilation function in addition to cooling and heating, its structure requires at least two blowers, making it expensive.

The present invention has been made in view of the problems of the prior art, and its purpose is to heat bathtub water and cool the inside of the bathroom in addition to heating and cooling the bathroom or washroom. The aim is to provide a heat pump device that can be used for multiple purposes such as a drying room for laundry and increase operating time, while also being more compact by housing parts in an integrated manner, resulting in lower equipment costs as a whole. It is something.

Further, 8b and 10b in Fig. 5 are internal partition plates provided above and below the blower 4 on the indoor side, and 12b and 13b in Fig. 6 are internal partition plates provided on both sides of the evaporator 3 on the outdoor side. It is a partition plate.

The casing 7 is configured as described above,
This is attached to the outer wall 14 of the bathroom or washroom of the building, and by appropriately opening and closing the opening/closing shutter at the vent and operating the blower 4, outdoor and indoor air is brought into contact with the evaporator 3. Figure (indoor →
It is possible to flow in each direction as shown by solid line arrows in FIG. 8 (outdoor to outdoor), FIG. 9 (outdoor to indoor), and FIG. 10 (indoor to outdoor).

Next, an embodiment of a heat pump device using the above-mentioned casing 7 is shown in FIGS. 11 to 15 (compressor etc. are omitted from illustration). FIG. 11 shows the case of bath heating, where 7 is a casing installed above an outer wall 14 between an indoor 6 such as a bathroom or washroom and an outdoor 5, and 17 is a refrigerant pipe 16 connected to this casing 7. This is a condenser connected to the bathtub 15 and provided inside the bathtub 15. In this case, normally, as shown by the dashed arrow in the figure,
Heat collection is performed by outdoor intake → outdoor exhaust, and the bath water is heated by passing the high-temperature gaseous refrigerant from the compressor in the casing 7 to the condenser 17 (the switching valve 20a is closed, and the condenser No refrigerant flows through 20).

Note that if there is a risk of frost forming on the evaporator 3 inside the casing 7 due to the low temperature in winter, the method is switched from indoor air intake to outdoor air intake as shown by the solid line arrow in the figure. Fig. 12 shows a case where the operation of the compressor inside the casing 7 is stopped and only the blower 4 is operated in forward and reverse directions for ventilation, and Fig. 13 shows the case of indoor cooling, in which waste heat is not released outdoors and the condenser 17 It can be used for bath heating.
