DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom circulating ventilation means for circulating and ventilating air in a bathroom through a bathroom circulating passage provided outside the bathroom, and a heating medium supplied from an external heat source unit. The present invention relates to a heating device provided with a bathroom heat exchanger for heating air passing through a circulation circuit.

[0002]

2. Description of the Related Art The above-described heating device is for heating a bathroom before bathing or drying the bathroom, for example. In such a heating device, conventionally, an external heat source device is used. The supplied heat medium was configured to be supplied to the bathroom heat exchanger through a supply path, and then returned to an external heat source device through a return path.

[0003]

In the above-described conventional configuration, the amount of heat of the heat medium supplied from the external heat source unit is expected to be the maximum at which heat exchange is expected to be performed in the heat exchanger in order to perform the heating function. Although it will be set to a value sufficiently larger than the amount of heat, after passing through the heat exchanger, since the heat medium returns to the external heat source device as it is, the surplus heat is not used However, there is a disadvantage that the efficiency of using heat generated by the heat source device cannot be said to be good.

On the other hand, for example, when taking a bath, it is preferable to heat not only the inside of the bathroom but also a separate room such as a dressing room. In the above-described conventional configuration, the heating effect of the heat exchanger is applied to the bathroom. In order to heat the separate room in this way, it is conceivable to provide a dedicated heating facility separately,
In such a case, a dedicated heat exchanger for the separate room is provided, and a dedicated heat medium circulation pipe is required for this heat exchanger with an external heat source unit. However, there are disadvantages in that the construction of the apparatus becomes large and the cost increases.

The present invention has been made in view of such a point, and an object of the present invention is to make use of the amount of heat of a heat medium supplied from a heat source device as efficiently as possible with a reasonable configuration. An object of the present invention is to provide a heating device which can improve efficiency and can heat a separate room without significantly complicating piping work or the like.

[0006]

According to the first aspect of the present invention, the air in the bathroom is circulated through the bathroom circulation path by the bathroom circulation ventilation means, and the air passing through the bathroom circulation path is passed through the bathroom circulation path. Is heated by the bathroom heat exchanger to which the heat medium is supplied from the external heat source device, so that the interior of the bathroom is heated. On the other hand, air in a separate room different from the bathroom is circulated and ventilated by a separate room circulating ventilation means through a separate room circulating passage provided outside the separate room, and the circulated and ventilated air in another room is supplied to the separate room heat exchanger. It is heated by. Therefore, the heat medium supplied to the bathroom heat exchanger by the external heat source device can be effectively used to heat not only the bathroom but also another room, and the heat use efficiency can be improved.

[0007] The separate-room heat exchanger heats air in another room by a heat medium supplied from the external heat source unit to the bathroom heat exchanger. A part of the piping for the bathroom heat exchanger can be used without providing a dedicated reciprocating ventilation path for circulating the heat medium between the heat exchanger and the piping, thereby simplifying the piping work. Becomes possible.

Further, the heat medium supplied from the external heat source unit is provided in series with a bathroom heat exchanger, a separate room heat exchanger, and a heat medium connecting / disconnecting means for interrupting the flow of the heat medium. The heat medium is configured to be circulated and supplied through the heat medium supply path provided, so that the heat medium for interrupting the flow of the heat medium is separately supplied to each of the bathroom heat exchanger and the separate room heat exchanger. Compared with the configuration in which the intermittent means is provided, the heat medium intermittent means can be shared, the configuration for intermittently supplying the heat medium to each heat exchanger can be simplified, and the heat exchangers are close to each other. By arranging it at a location, the connecting pipe for flowing the heat medium can be made as short as possible, and there is also an advantage that the labor for piping can be reduced.

According to a second feature of the present invention, in the first feature of the present invention, the separate-room heat exchanger is disposed closer to the heat medium flow direction than the bathroom heat exchanger.

That is, the heat medium supplied from the external heat source unit is first supplied to the separate room heat exchanger and then supplied to the bathroom heat exchanger. On the other hand, since the heat medium is supplied with a sufficient amount of heat, the heating capacity of the heat exchanger is guaranteed. As a result, even if a small-sized heat exchanger for a separate room having a small heat capacity is used, the heating function can be exhibited, and the equipment can be downsized accordingly.

According to the characteristic configuration of the third invention, in the separate-room circulation path, the separate-room heat exchanger is provided so as to be located on the upstream side in the air flow direction with respect to the separate-room circulation ventilation means. .

The air in the separate room is sucked from the upper side in the air flow direction by the separate room circulation ventilation means, is discharged from the lower side in the air flow direction, and is circulated and ventilated.
When passing through the separate-room heat exchanger, air is passed by suction. The heat exchanger has a large ventilation resistance, and if you try to ventilate it with exhaust air, it may not flow smoothly, but because the air flows by suction, it surely passes through the inside of the heat exchanger. In addition, since there is no portion having a large exhaust resistance on the lower side in the air flow direction of the separate room circulation ventilation means, the circulation ventilation is performed smoothly. As a result, the ventilation heating of the separate room is performed smoothly.

[0013] According to the characteristic configuration of the fourth invention, based on the heating command of the bathroom heating command means, the control means starts the operation of the bathroom circulation ventilation means, and controls the heat medium to the bathroom heat exchanger. Control is performed to start the supply, and the bathroom is heated. Further, based on the heating command of the separate room heating command means, the control means controls to start the operation of the separate room circulation ventilation means and to start supplying the heat medium to the separate room heat exchanger. , Heating of another room will be performed.

Therefore, it is possible to separately instruct the heating of the bathroom and the heating of the separate room in accordance with the use condition, which is convenient.

According to the characteristic configuration of the fifth invention, since the separate room is a dressing room adjacent to the bathroom, for example, not only heating of the bathroom but also heating of the dressing room is performed before bathing. Undressing and the like can be performed at a comfortable temperature.
