Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom ventilation dryer, which is provided on the ceiling of a bathroom to dry laundry and to ventilate and heat the bathroom.

[0002]

2. Description of the Related Art In recent years, as the number of couples working together has increased, there has been a growing demand for laundry to be dried indoors, and bathroom ventilation dryers that use a bathroom as a place for drying laundry have become widespread.

Conventionally, in this type of bathroom ventilation dryer, there are a type in which a drying operation is performed by using two fans for ventilation and a circulation, and a type in which a drying operation is performed by one fan. The type that performs the drying operation with the one blower is the actual Kaihei 2-2
The configuration shown in Japanese Patent No. 4223 has been common. The configuration will be described below with reference to FIGS. 6 and 7.

As shown in the drawing, a blower 101 is opened inside, a damper 105 for switching the blown air 102 of the blower 101 to a bathroom side air passage 103 and a ventilation air passage 104, and a damper 105 are driven. A ventilation motor main body 1 in which a damper motor 106 is provided, a heater 107 is provided in the air passage 103 on the bathroom side, and a ventilation port 109 to which a duct 108 communicating with the outdoors is connected is formed on the side portion 1.
10 was provided in the ceiling of bathroom 111.

A decorative panel 114 having a suction port 112 and an outlet 113 formed in a shape covering the lower surface opening of the main body 110 is attached to the lower surface of the main body 110.

In the above structure, in ventilation operation, the damper 105 is switched to a position for closing the air passage 103 on the bathroom side, and the blower 101 causes the suction port 112 of the decorative panel 114 provided on the lower surface of the main body 110 to open the bathroom 111. Air is sucked into the main body 110 and is discharged to the outside through the ventilation air passage 104, the ventilation port 109, and the duct 108.

Further, in the heating operation, the damper 105 is switched to a position for closing the ventilation air passage 104, and the blower 10
1. The decorative panel 11 provided on the lower surface of the main body 110
Air from the bathroom 111 is sucked into the main body 110 through the suction port 112 of No. 4 and heated by the heater 107.
5 is blown out from the air outlet 113 to heat the bathroom 111.

In the dry operation, the laundry is dried by alternately performing the heating operation and the ventilation operation. That is, the warm air 115 generated by the heating operation is applied to the laundry 116 suspended in the bathroom 111 to dry the laundry 116. The moisture removed from the laundry 116 raises the absolute humidity of the air in the bathroom 111 so that the laundry 116 cannot be dried. Therefore, after a certain period of time, the ventilation operation is switched to the blower 101 to remove the moist air in the bathroom. After discharging it outdoors, switch to heating operation again. The laundry 116 was dried by repeating the heating operation and the ventilation operation.

[0009]

In such a conventional bathroom ventilation dryer, since the drying operation is performed by repeating the heating operation and the ventilation operation, the amount of laundry 116 during the drying operation,
There is a problem that it is necessary to change the ratio of the time of heating operation and the time of ventilation operation depending on various load conditions such as the outside temperature and humidity of the bathroom 111.

SUMMARY OF THE INVENTION The first object of the present invention is to provide a bathroom ventilation dryer having a short drying time by simultaneously performing heating and ventilation during a drying operation.

A second object is to shorten the drying time by adjusting the proper ventilation amount according to the load during the drying operation.

[0012]

In order to achieve the above-mentioned first object, the bathroom ventilation dryer of the present invention is a ventilation dryer in which the first means has a lower surface opened and a ventilation opening is formed on the side. The main body, a decorative panel in which a suction port and a blowout port are formed in a shape that covers the lower surface of the main body, a blower provided in communication with the suction port inside the main body, and blown air of this blower through a heat exchanger. A damper that distributes to the air passage on the bathroom side that communicates with the air outlet and the ventilation air passage that communicates with the ventilation opening, a damper motor that drives this damper, and a control unit that controls this drive motor and the blower. The damper is controlled so that the air passage or the ventilation air passage on the bathroom side is closed and the air is blown to both the air passage and the ventilation air passage on the bathroom side at the same time.

In order to achieve the second object, the second
This means installs a room temperature detection sensor connected to the control unit near the suction port of the decorative panel, and closes the air passage on the ventilation port side during the dry operation while the room temperature detected by the room temperature detection sensor is below the set value. However, when the humidity detected by the room temperature detection sensor becomes equal to or higher than the set value, a part of the blown air flows to the ventilation port side, and the opening degree of the damper is controlled so that the room temperature becomes the set temperature.

[0014]

According to the present invention, by the structure of the first means described above, during the drying operation, the air blown by the blower is distributed to the heat exchanger side and the exhaust port side by the control of the damper, and is blown out into the bathroom by the action of the heat exchanger. The laundry is dried with warm air that is generated, and due to the evaporation of water from the laundry, some of the air in the bathroom, whose absolute humidity has risen, is exhausted from the ventilation opening, which results in effective drying. Become.

Further, by the structure of the second means, during the drying operation, the opening degree of the damper is controlled so that the temperature in the bathroom becomes the set temperature, so that the drying operation can be performed with the optimal ventilation amount for the drying regardless of the load. Will be done.
