Description

[Detailed Description of the Invention] The present invention relates to an apparatus for boiling hot water using a heat pump, and particularly to a structure for promoting heat exchange in an outdoor heat exchanger and ventilation in a bathroom.

Recently, for example, air-conditioning devices using heat pumps have been in the spotlight. However, in conventional devices using heat pumps, a structure is generally adopted in which an indoor unit and an outdoor unit are formed, and the two units are connected by appropriate piping. The following problems have arisen: That is, an indoor unit is attached to a wall in a room and extends into the room, and an outdoor unit is placed, for example, on a balcony or the like, where it becomes a hindrance for feet or reduces the floor area of the balcony or the like.

Particularly, outdoor units have a structure in which, for example, a fan motor is installed behind the heat exchanger, and the air that has passed through the heat exchanger is discharged to the rear as it is. However, in such a structure, the thickness of the device becomes large, and the air suction surface and air discharge surface are different, which limits the installation location.

Additionally, it is generally desired that bathrooms be easily and well ventilated.

Therefore, the present invention configures the heat pump as one unit, fits the heat pump unit into an opening formed in the wall of the bathroom, and gives the heat pump unit the role of a wall and a flow water heater. The purpose is to eliminate the above-mentioned conventional drawbacks and problems.

Another purpose of the present invention is to reduce the thickness of the outdoor heat exchanger and the part including the fan motor combined therewith, and to make the air suction surface and the air discharge surface face the same direction, thereby achieving the above purpose. It is in.

Still another object of the present invention is to use the fan motor to ventilate a bathroom, thereby reducing product costs.

The present invention includes a casing that is fitted into an opening formed in a wall of a bathroom and serves as a wall, and a heat pump assembled to the casing. and an outdoor heat exchanger assembled at a lower position of the casing, and the casing has an inner cover facing the inside of the bathroom and an outer cover facing the outside of the bathroom. A partition plate is provided above the outdoor heat exchanger, leaving a ventilation gap with respect to the inner cover, a fan motor and a fan duct are provided on the partition plate, and the outdoor heat exchanger is provided with a fan motor and a fan duct on the partition plate. An inlet facing the exchanger and an outlet facing the fan motor are provided, and the inner cover is provided with a ventilation port that can be freely opened and closed and communicates with the fan duct, and the fan motor is provided with an air inlet in the fan duct. There is obtained a flow heat pump unit characterized in that the heat pump unit is configured to bias the heat pump toward the discharge port.

Hereinafter, the present invention will be described using examples with reference to the drawings.

First, referring to FIG. 1, a relatively large opening penetrating both the inside and the outside is formed in the wall of a bathroom 1, and a heat pump unit 2 is fitted into the opening. The heat pump unit 2 includes a casing that essentially functions as a wall and a heat pump built into the casing.

The heat pump in the heat pump unit 2 has a heat exchanger 4 for hot water heating exposed outside the housing and inserted into the bathtub 3. This exchanger 4 is one of the indoor heat exchangers. In this manner, water can be boiled in the bathtub 3 by condensing the refrigerant in the heat exchanger 4 during operation of the heat pump.

Referring also to FIGS. 2 to 4, the heat pump further includes an indoor temperature control heat exchanger 5, which is another indoor heat exchanger, which is incorporated in the upper part of the casing, and a casing. It includes an outdoor heat exchanger 6 and a compressor 7, which are installed in the lower part of the body.
In this way, this heat pump is not only capable of boiling water in the bathtub 3 using the heat exchanger 4 for boiling hot water, but also is capable of boiling water in a suitable air duct (not shown) using the heat exchanger 5 for indoor temperature control. ) can also be used to cool or heat other rooms. Therefore, it can be said that this heat pump unit 2 is an air-conditioning device with a water heater.

On the other hand, the casing of the heat pump unit 2 has an outer cover 8 facing outside the bathroom 1 and an inner cover 9 facing into the bathroom 1.

Before attaching the outer cover 8 to such a case, install the fan duct 1 above the outdoor heat exchanger 6.
1 and the partition plate 12 that abuts against the lower surface of the fan duct, and the inner cover 9 is provided with a ventilation gap 13.
Leave and attach. Then, a fan motor 15 attached to a motor stand 14 is attached onto the partition plate 12. Finally, attach the outer cover 8. This outer cover 8 is formed with an inlet 16 facing the outdoor heat exchanger 6 and an outlet 17 facing the fan motor 15. These inlets 16
Both the discharge port 17 and the discharge port 17 are composed of a large number of slits. On the other hand, the inner cover 9 is provided with a ventilation opening 19 that communicates with the fan duct 11 through a gap 18 and the like and can be opened and closed. In this way, when the fan motor 15 is operated, the suction port 16
The air sucked in from the outdoor heat exchanger 6 passes through the ventilation gap 13 and is discharged from the discharge port 17, and when the ventilation port 19 is open, the air from the bathroom 1 flows through the gap 18 and the fan duct. 11 and is discharged from the same discharge port 17.

By the way, an example of the refrigerant circuit of the heat pump used is shown in FIG. In FIG. 5, 21 is a four-way valve for switching the connection between the outdoor heat exchanger 6 and the indoor temperature control heat exchanger 5, 22 is a solenoid valve for bypassing the flow water heating heat exchanger 4, and 23
is a capillary, 24 is a gas-liquid separator, and 25 is a fan motor. Note that solid line arrows indicate the flow of refrigerant when a room other than bathroom 1 is cooled, and dashed line arrows indicate a flow of refrigerant when heating a room other than bathroom 1.

According to this structure, since the fan motor 15 is installed above the outdoor heat exchanger 6, the thickness of this part can be reduced.
Since both the and the outlet 17 are provided on the outer cover 8, it is extremely convenient to fit into an opening formed in the wall of the bathroom 1, for example. Further, since the promotion of heat exchange in the outdoor heat exchanger 6 and the ventilation of the bathroom 1 are performed by one fan motor 15, the cost of the product can also be reduced.
