[0002]

2. Description of the Related Art Conventionally, a bathroom has been heated,
As a bathroom heater / dryer that can perform ventilation, a circulation path that circulates and circulates the air in the bathroom is formed, and a circulation fan that circulates the circulation path forcibly and an air in the bathroom that circulates 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 the circulation fan, the air in the bathroom is sucked along the circulation path and the heat exchanger is used. It is configured to heat the bathroom by heating it again after heating it, and switch the state of the bathroom air to the outside by the circulation fan, or exhaust the bathroom air to the outside. There has been a configuration in which a ventilation fan for doing so is separately provided so that ventilation can also be performed. Then, for example, in the case of 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 heating / drying machine. In other words, a circulation path for circulating the air in the separate room, a circulation fan for circulating the air, a heat exchanger for heating the air, and a ventilation fan for exhausting the air in the separate room to the outside are provided separately. .

[0003]

However, as described above, in the configuration in which the separate room is provided with the same equipment as the equipment for the bathroom, the construction becomes complicated and much construction work is required. There is a disadvantage that the cost of the entire equipment is high. That is, since the equipment for the separate room is provided separately from the equipment for the bathroom, a device main body portion for accommodating the above-mentioned members is required separately, and a device main body portion for the bathroom equipment and a device main body portion for the separate room equipment are provided. It is necessary to separately attach each of them to a fixed part such as a wall of a building, which increases the labor for construction. In addition, a ventilation fan and an exhaust path for exhausting the outside air to the outside are separately required, which increases the number of members and requires a lot of labor for constructing the exhaust path.

The present invention has been made by paying attention to such a point, and an object thereof is to make it possible to heat a bathroom and a separate room and to perform ventilation, but have a simple structure. In addition, it is a point to provide a bathroom heater / dryer with a multi-room ventilation function, which requires less construction work and enables cost reduction.

[0005]

According to the characteristic construction of the first invention, the air in the bathroom is circulated by the bathroom circulation fan through the bathroom circulation passage provided outside the bathroom.
The bathroom heat exchanger supplied with the heat medium from the external heat source machine heats the air passing through the bathroom circulation path to heat the bathroom. Then, the separate room circulation fan circulates the air in the separate room, which is different from the bathroom, so that the air passes through the separate room circulation path and is heated by the separate room heat exchanger to which the heat medium is supplied from the external heat source unit and returns to the separate room. A separate room is heated by ventilation.

Further, since the ventilation passage for exhausting the air in the bathroom to the outside and the circulation passage for the separate room are formed, together with the air in the bathroom, along with the operation of the ventilation fan, The air in the separate room is taken in through the separate room circulation path and exhausted to the outside.

Therefore, the circulation fan for the bathroom, the heat exchanger for the bathroom, the ventilation fan, and the heat exchanger for the separate room are provided in the main body of the apparatus, respectively, and the heat exchanger for the separate room is provided in the main body of the apparatus. By arranging the air in the separate room to circulate through the separate room circulation path, the structure is simpler and more time-consuming than the case where the separate device main body is installed in addition to the bathroom main body. 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 separate room together with the air in the bathroom is also sucked through the circulation path for the separate room along with the operation of the ventilation fan. Will be exhausted to.

As a result, the separate room circulation path for heating the separate room is also used as the ventilation path for ventilation, and it is not necessary to provide a separate ventilation path for the separate room ventilation, and the structure can be simplified. It will reduce the time and effort required for plumbing.

According to the characterizing feature of the second invention, the communication passage is made to communicate with a passage portion other than the intermediate passage portion between the heat exchanger for another chamber and the circulation fan for another chamber in the circulation passage for another chamber. Since it is configured, there is no member that serves as ventilation resistance in the passage portion that connects the ventilation fan and the inside of the separate room, and the intake operation by the ventilation fan is efficiently performed.

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

According to the characterizing feature of the fourth aspect of the invention, the opening / closing means is constituted so as to be energized in the shielding state and to be switched to the open state by the ventilation force by the operation of the ventilation fan. Therefore, for example, in a configuration in which the state of the opening / closing means is separately instructed to be switched, the opening / closing means may be erroneously switched to the open state when the heating operation of the separate room is performed, but the ventilation operation is executed. Only when the opening / closing means is switched to the open state by the ventilation force of the ventilation fan, it is possible to avoid the inconvenience of the opening / closing means being opened when the separate room is heated due to an 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 of which are provided in the main body of the apparatus. Since it is configured as described above, it is possible to share the heat medium supply pipe from the external heat source device and also to connect the supply pipe and the heat medium circulation path on the apparatus main body side together. It is possible to reduce the labor of constructing the heat medium pipe.

According to the characterizing feature of the sixth aspect of the invention, the undressing room adjacent to the bathroom and used for undressing at the time of bathing can be heated, for example, prior to bathing, and can be ventilated after bathing. It can be done and is easy to use.
