Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom air conditioner capable of air-conditioning a bathroom and an adjacent room such as a washroom.

[0002]

2. Description of the Related Art A large number of bathroom air conditioners for drying, heating and ventilating a bathroom have been proposed, for example, as disclosed in Japanese Patent Application Laid-Open No. 9-48663.

This bathroom air conditioner is provided with air conditioning equipment such as a circulation fan for circulating the air in the bathroom, a ventilation fan for discharging the air in the bathroom to the outside, and an electric heater for heating the air in the bathroom. The bathroom is dried by supplying electricity to the circulation fan, electric heater and ventilation fan, and the bathroom is heated by supplying electricity to the circulation fan and electric heater. The bathroom is ventilated by.

[0004]

By the way, since hot water is also used in the washroom adjacent to the bathroom, steam may be generated in the washroom and ventilation of the washroom may be required.
In addition, in the winter season, the temperature of the washroom is so low that heating may be required.

[0005] However, the ventilation and heating of the conventional bathroom air conditioner are limited to the bathroom only. Therefore, when performing ventilation or heating of the washroom, a separate ventilation or heating device is installed in the washroom. The air conditioning range of this air conditioner has been narrowed.

An object of the present invention is to provide a bathroom air conditioner capable of ventilating or heating not only a bathroom but also a room adjacent thereto in view of the above-mentioned conventional problems.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a bathroom air conditioner equipped with a ventilation fan for sucking in air from a bathroom and discharging the air to the outside. The structure has a suction duct which communicates with the adjacent room and guides the air in the room to the ventilation fan.

According to the present invention, by driving the ventilation fan, the bathroom air is discharged outside,
Air in a room adjacent to the bathroom (for example, a washroom) is guided to a ventilation fan through a suction duct and discharged outside.

A second aspect of the present invention is a bathroom air conditioner including a circulating fan for sucking in the bathroom air and blowing it out again into the bathroom to circulate the bathroom air, and a heating device installed in an air passage of the circulating air. The apparatus has a structure having a blow duct for guiding a part of the circulating air heated by the heating apparatus to the washroom.

According to the present invention, by driving the circulation fan, the bathroom air is heated by the heating device and circulated to the bathroom, so that the bathroom can be heated, and the bathroom can be heated through the outlet duct. Because the blown air is blown, the washroom can be heated.

A third aspect of the present invention provides a ventilation fan for sucking in bathroom air and discharging it to the outside, a circulating fan for sucking in bathroom air and blowing it out again to the bathroom to circulate the bathroom air, and In a bathroom air conditioner provided with a heating device installed in an air passage, a suction duct that communicates with a room adjacent to the bathroom and guides air in the room to a ventilation fan, and one of circulating air heated by the heating device And a blow duct for guiding the section to a room adjacent to the bathroom.

According to the present invention, the bathroom and the washroom are ventilated by driving the ventilation fan, and the bathroom and the washroom are heated by driving the circulation fan.

According to the invention of claim 4, the ventilation amount of the bathroom and the lavatory is controlled by a damper, and only one room is ventilated, or the ventilation ratio of each room is arbitrarily changed. Is also good. Further, as in the invention of claim 5, the amount of air for heating the bathroom and the washroom is controlled by a damper, and only one of the rooms is heated, or the heating ratio of the bathroom and the washroom is arbitrarily changed. You may.
