Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath dryer for performing ventilation while drying clothes and a bathroom in a bathroom.

2. Description of the Related Art In recent years, treatment of moisture when clothes are dried in a bathroom has been emphasized, and a bathroom dryer has been required.

As shown in FIGS. 4 and 5, the above dryer has a bathroom dryer main body 201, which includes a bathroom side suction port 202, a bathroom side return air suction port 203, a bathroom side discharge port 204, and an outdoor side suction port 205.
The outdoor outlet 206 is provided, the motor 209 having the air supply blade 207 and the exhaust blade 208 is provided inside, and the heater 210 is provided.

In the above-described configuration, the air in the bathroom is entered through the bathroom-side suction port 202 and exhausted through the outdoor-side discharge port 206 by the exhaust blade 208. On the other hand, the outdoor air enters from the outdoor suction port 205 by the air supply blades 207, merges with the air entering from the bathroom side return air suction port 203, is heated through the heater 210, and enters the bathroom from the bathroom side discharge port 204. The heated air was being supplied.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above-described conventional bath dryer, when operating, the heat in the bathroom is exhausted as it is to the outside by the exhaust blade 208, and the outdoor air is also heated by the supply blade 207. Since the air is supplied to the bathroom as it is through 210, it takes a long time to dry the clothes and the bathroom in the bathroom, and it is not possible to intensively exhaust the steam in the bathroom, which causes mold. There was a fear that the electricity usage fee would increase.

The present invention is to solve the above-mentioned conventional problems, and when operating, it is possible to dry clothes and the bathroom in the bathroom in a short time, and because steam in the bathroom can be exhausted intensively, It is an object of the present invention to provide a bath dryer that prevents the generation of mold and requires less electricity.

Means for Solving the Problem In order to solve this problem, the present invention provides an exhaust ventilation passage extending from a bathroom-side inlet through a blade B to an outdoor side opening B, a blade A and a heater from an outdoor side opening A. An air supply air passage leading to the bathroom side discharge port is formed, a heat exchanger is provided at the intersection of the air supply air passage and the exhaust air passage, and a bathroom side return air inlet is provided in the air supply air passage. A communication opening is provided in the middle of the air supply passage for bypassing the flow passage, and an opening / closing damper for opening and closing the air supply passage and the communication opening is provided near the communication opening.

Action With this configuration, when the motor having the blades A and B is operated, the air in the bathroom enters through the suction port on the bathroom side, passes through the blades B, and is discharged from the outdoor side opening B through the heat exchanger. The outdoor air enters through the outdoor opening A, passes through the heat exchanger, recovers the heat of the exhausted air, merges with the air entering through the return air inlet on the bathroom side, and passes through the blade A to drive the heater. As is the case, air is supplied to the bathroom from the bathroom outlet. Further, by turning off the heater and opening the open / close damper, a damper exhaust passage connected through the communication port is formed. In this case, when the motor having the blades A and B is operated, the air in the bathroom enters through the inlet on the bathroom side, passes through the blades B, passes through the heat exchanger, and is discharged from the outdoor opening B.
In addition, it enters through the return air suction port on the bathroom side, passes through the blade A, passes through the heat exchanger through the communication port, and the outdoor side opening A
Will be discharged more.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, 1 is the opposite of the bath dryer, and on the front,
A front panel 5 having a bathroom-side suction port 2, a bathroom-side return air suction port 3 and a bathroom-side discharge port 4 is attached, and at the rear part,
An outdoor opening A6 and an outdoor opening B7 are provided. Inside the main body 1, there is an exhaust ventilation passage 8 that extends from the bathroom-side suction port 2 to the outdoor-side opening B7, and the bathroom-side discharge port 4 from the outdoor-side opening A6.
An air supply ventilation passage 9 is formed. The bathroom-side return air suction port 3 communicates with the air supply ventilation passage 9. Part of the exhaust ventilation passage 8 and the air supply ventilation passage 9 are
The heat exchangers 10 provided in the main body 1 are crossed with each other, and the exhaust ventilation passage 8 and the supply air ventilation passage 9 are provided.
Are provided with blades A12 and blades B13 driven by the motor 11. In the air supply ventilation passage 9, the heater 14, the communication port 15, and the communication port 15 are provided on the bathroom side discharge port 4 side.
Opening and closing dampers 16 for opening and closing are provided on both sides.

In the above configuration, as shown in FIGS. 1 and 2,
When the motor 11 having the blades A12 and B13 is operated, bathroom air enters from the bathroom-side suction port 2, heat is exchanged through the blades B13 and the heat exchanger 10, and then from the outdoor opening B7 to the outside. Is discharged. On the other hand, the outdoor air flows through the outdoor opening 6
After entering more and performing heat exchange through the heat exchanger 10,
Combining with the air entering from the return air suction port 3 on the bathroom side,
After passing through the blade A12 and being heated by the heater 14, the air is supplied to the bathroom from the bathroom-side discharge port 4. In this way, the heat in the bathroom is used to suppress an increase in load and perform ventilation. Further, when the heater 14 is turned off, the opening / closing damper 16 is opened, and the motor 11 having the blades A12 and B13 is operated, as shown in FIG.
3 through the heat exchanger 10, is discharged to the outside through the outdoor opening B7, and the bathroom air enters through the bathroom-side return air suction port 3, passes through the blade A12, and heats through the communication port 15. It passes through the exchanger 10 and is discharged to the outside from the outdoor opening A6. In this way, steam can be exhausted intensively and quickly in the bathroom, so that mold can be prevented.

As described above, according to the present embodiment, by providing the heat exchanger 10 and the opening / closing damper 16, it is possible to dry clothes in the bathroom and the bathroom in a short time, and intensively exhaust steam in the bathroom. Prevents mold from occurring,
Moreover, the electricity usage fee is low and effective ventilation can be performed.

EFFECTS OF THE INVENTION As is clear from the description of the embodiments, the present invention includes an opening / closing damper for opening and closing the communication port in the air supply ventilation passage, and heat exchange is performed at the intersection of the air supply ventilation passage and the exhaust ventilation passage. By providing the vessel, clothes in the bathroom and the bathroom can be dried in a short time, and steam in the bathroom can be exhausted intensively, so that mold can be prevented from occurring.
Moreover, the utility effect is great because the electricity usage fee is low.
