DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom heating / drying machine having a multi-room ventilation function capable of heating a bathroom or another room other than the bathroom and ventilating those rooms.

[0002]

2. Description of the Related Art Conventionally, a bathroom has been heated,
As a bathroom heater / dryer capable of ventilation, a circulation path for circulating and ventilating the air in the bathroom is formed, and a circulation fan for forcibly circulating air in the circulation path, and air in the bathroom flowing in the circulation path. Is provided with a heat exchanger for heating with a heat medium supplied from an external heat source device, and by operating a circulation fan, air in the bathroom is taken in along the circulation path, and the heat exchanger By supplying air to the bathroom again after heating, the bathroom is configured to be heated, and the circulation fan is switched to a state in which the air in the bathroom is exhausted to the outside, or the air in the bathroom is exhausted to the outside. There is a configuration in which a ventilation fan is separately provided to perform ventilation. When heating and ventilating another room different from the bathroom such as a dressing room adjacent to the bathroom, it is conceivable to provide the same equipment as the bathroom heater / dryer. That is, a circulation path for circulating and ventilating the air in another room, a circulation fan for flowing the air, a heat exchanger for heating the air, a ventilation fan for exhausting the air in the other room to the outside, and the like are separately provided. .

[0003]

However, as described above, in a configuration in which the separate room is provided with facilities similar to the facilities for the bathroom, the configuration becomes complicated and the construction takes much time. There is a disadvantage that the cost of the entire equipment is high. In other words, since the separate room equipment is provided separately from the bathroom equipment, an apparatus main body for accommodating the above members is separately required, and the apparatus main body of the bathroom equipment and the apparatus main body of the separate room equipment are required. Need to be separately attached to a fixed portion such as a wall of a building, and the construction time is increased accordingly. In addition, a ventilation fan and an exhaust path for exhausting the outside air to the outside are required separately, so that the number of members is increased and the labor of construction of the exhaust path is increased.

The present invention has been made in view of such a point, and an object of the present invention is to provide a simple structure in which a bathroom and a separate room can be heated and can be ventilated. Another object of the present invention is to provide a bathroom heating / drying machine with a multi-room ventilation function, which can reduce the labor of construction and reduce costs.

[0005]

According to the first aspect of the present invention, the bathroom air is circulated and ventilated by a bathroom circulation fan through a bathroom circulation path provided outside the bathroom.
The air passing through the bathroom circulation path is heated by the bathroom heat exchanger to which the heating medium is supplied from the external heat source device, and the bathroom is heated. The separate-room circulation fan circulates the air in the separate room, which is different from the bathroom, through the separate-room circulation path and heated by the separate-room heat exchanger to which the heat medium is supplied from the external heat source device, and returns to the separate room. A separate room is heated by ventilation.

[0006] Further, since a ventilation path for exhausting the air in the bathroom to the outside and a circulation path for communicating with the separate-room circulation path are formed, the ventilation fan is operated together with the air in the bathroom in accordance with the operation of the ventilation fan. The air in the different room is sucked in through the separate room circulation path and exhausted to the outside.

Accordingly, each of the bathroom circulating fan, the bathroom heat exchanger, the ventilation fan, and the separate room heat exchanger is provided in the apparatus main body, and the separate room heat exchanger provided in the apparatus main body is provided. By circulating the air in the separate room through the circulation path for the separate room, the structure is simpler and more labor intensive than in the case where the device body for the separate room is separately installed in addition to the device body for the bathroom. Can be reduced.

Further, since the circulation path for the separate room and the ventilation fan communicate with each other through the communication passage, the air in the other room is taken in through the circulation path for the separate room together with the air in the bathroom, and the external air is blown together with the operation of the ventilation fan. Will be exhausted.

As a result, a separate circuit circulation path for heating the separate room is used also as a ventilation path for ventilation, and there is no need to separately provide a ventilation path dedicated to separate room ventilation, so that the structure can be simplified and The piping work is reduced.

According to the characteristic structure of the second invention, the communication passage communicates with a passage portion other than an intermediate passage portion between the separate room heat exchanger and the separate room circulation fan in the separate room circulation passage. Because of this configuration, there is no member serving as a ventilation resistance in a passage portion that connects the ventilation fan and the inside of the separate room, and the air intake operation by the ventilation fan is performed efficiently.

According to the characteristic structure of the third invention, the communication passage is provided with opening / closing means which can be switched between a state of blocking the passage and a state of opening the passage. For example, when heating a separate room, By switching the opening / closing means to a shielded state, it is possible to prevent the air in another room heated by the heat exchanger for another room from leaking outside through a ventilation fan, and to open the opening / closing means when ventilating another room. By switching, ventilation can be performed effectively.

According to the characteristic structure of the fourth invention, the opening / closing means is configured to be urged to the shielded state and to be switched to the open state by the flow of wind by the operation of the ventilation fan. Therefore, for example, in a configuration in which the state of the opening / closing unit is separately switched, there is a possibility that the opening / closing unit may be erroneously switched to the open state when performing the heating operation of another room, but the ventilation operation is performed. Only when the opening / closing means is switched to the open state by the ventilation wind of the ventilation fan, it is possible to avoid inconveniences such as the opening / closing means being opened when another room is heated due to erroneous operation.

According to the fifth aspect of the invention, the heat medium supplied from the external heat source unit is circulated and supplied in series to the bathroom heat exchanger and the separate room heat exchanger both provided in the apparatus main body. With this configuration, it is possible to share the heat medium supply pipe from the external heat source unit, and to share a connector and the like between the supply pipe and the heat medium circulation path on the apparatus main body side. The work of installing the heat medium piping can be reduced.

According to the sixth aspect of the present invention, the undressing room adjacent to the bathroom and used for undressing when taking a bath can be heated, for example, prior to taking a bath, and ventilation can be provided after taking a bath. It can be done and is easy to use.
