DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom heating device for heating the circulating air to heat the bathroom while circulating the air in the bathroom, and to circulate the air in other rooms.
The present invention relates to a bathroom heating device having a heating function for another room, comprising a heating device for another room, which heats the circulating air to heat the other room.

[0002]

2. Description of the Related Art In such a bathroom heating device with a heating function for another room, a heating device for a bathroom and a heating device for another room are conventionally integrated in order to simplify installation work.
The integrated heating device is placed above the bathroom ceiling,
An arrangement placed in the back of a bathroom is known (the document cannot be shown).

[0003]

However, the space above the ceiling in the bathroom is limited, and a heating device for the bathroom and a heating device for another room, for example, a heating device for a dressing room, are arranged in the limited space. Therefore, it is necessary to reduce the size of each heating device to some extent, and there is a problem that the heating capacity is limited.

The present invention has been made in view of such a point, and an object of the present invention is to make it possible to dispose a heating device for a bathroom and a heating device for another room in the back of a ceiling, despite the fact that the heating device for a bathroom and the other room can be arranged above the ceiling. It is an object of the present invention to provide a bathroom heating device with a heating function for another room, which can heat another room with a relatively large heating capacity.

[0005]

According to the first aspect of the present invention, a bathroom circulating fan and a bathroom heat exchanger that constitute a bathroom heating device, and another room that constitutes another room heating device. The heat exchanger for the other room is placed above the ceiling of the bathroom, and the circulation fan for the other room, which constitutes the heating device for the other room, is placed above the ceiling of the other room. Despite being able to be placed at the same time, compared to the conventional case where both heating devices are integrated and placed behind the ceiling of the bathroom, it can be placed by effectively using the space above the ceiling of other rooms it can. Therefore, it is possible to increase the size of the circulation fan and the heat exchanger that constitute each heating device, and it is possible to heat the bathroom and other rooms such as a dressing room and a toilet with a relatively large heating capacity. Since both the heat exchangers for the room and the other room can be arranged close above the ceiling of the bathroom, it is easy to cope with both the heat exchangers. That is,
If both heat exchangers that can be heated to high temperatures are arranged close to each other, for example, when performing heat insulation treatment, it is not necessary to separately perform heat insulation treatment for both heat exchangers, and it is also possible to use hot water as a heat medium. When such a method is used, it is easy to cope with both heat exchangers, for example, by shortening the pipe length.

According to the second aspect of the invention, in the circulation path for the undressing room, which communicates the suction portion and the blow-out portion provided in the other room, the other room circulation fan is located on the lower side in the air flow direction by the other room circulation fan. Since the heat exchanger is installed, the noise associated with the operation of the circulation fan can be achieved even if the space above the ceiling in the other room is effectively used and the circulation fan for the other room is enlarged to increase the heating capacity. It can be kept relatively small. In other words, since the intake-side noise and the discharge-side noise are generally lower than the intake-side noise, the noise generation can be suppressed to a low level by disposing the circulation fan for the other room on the intake section side. Even if the room circulation fan is large, noise can be relatively reduced.

According to the third aspect of the present invention, the other-room heat exchanger is assembled with the bathroom-heating device and integrated, so that the bathroom-heating device and the other-room heat device are disposed above the ceiling of the bathroom. The handling with the exchanger becomes easy, and the installation work above the ceiling of the bathroom can be simplified.

According to the present invention, the heat medium to the bathroom heat exchanger and the heat medium to the other room heat exchanger are supplied from a common external heat source unit. because there is,
The cost can be reduced by sharing the external heat source unit, and both heat exchangers can be arranged close to each other as described above, so that the entire length of the heat medium pipe can be shortened, and the entire apparatus can be reduced. Cost can be reduced.

According to the fifth aspect of the present invention, the ventilation fan for sucking air in the bathroom and forcibly exhausting the air outside the bathroom is assembled into the bathroom heating device, integrated and disposed above the ceiling of the bathroom. This makes it possible to ventilate the bathroom with the ventilation fan while facilitating the handling of the ventilation fan. In addition, the ventilation fan and the other room communicate with each other through the ventilation path for the other room, and the driving of the ventilation fan is performed. With this configuration, the air in the bathroom and the air in the other room are simultaneously forcibly exhausted, so that the humid bathroom and the other room can be ventilated by the common ventilation fan, and the ventilation fan The cost can be reduced by sharing the data.

According to the invention described in claim 6, there is provided an openable / closable outflow preventing means for preventing the air in the bathroom from flowing out into the other room via the other room ventilation path, and the ventilation fan is driven. Since the outflow prevention means is configured to close as it is stopped, such as when taking a bath in the bathroom, it is possible to prevent air containing much moisture in the bathroom from flowing into the other room side. It is configured so that the humidity in the other room is prevented from increasing and the outflow prevention means is opened as the ventilation fan is driven, so that the air in the bathroom and the air in the other room are simultaneously and , Can be effectively exhausted to the outside. As a result, while it is possible to prevent disadvantages caused by the flow of moisture-rich air in the bathroom into the other room, the ventilation fan can also be used, and the equipment can be simplified accordingly, resulting in cost reduction. Can be reduced.
