Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation dryer for a bathroom for discharging moisture or the like in a bathroom to the outside or warming the air in the bathroom.

[0002]

2. Description of the Related Art In recent years, it has become popular not only to ventilate a bathroom but also to heat the bathroom when taking a bath or to use the bathroom as a drying room.

[0003] As this type of conventional bathroom ventilation dryer, the one shown in Figs. 7 and 8 is generally used.

[0004] As shown in FIGS. 7 and 8, a circulating fan 102 circulating air in a bathroom by a circulating airflow 101.
, A ventilation fan 104 for discharging the air in the bathroom to the outside of the bathroom by the exhaust flow 103, a convection heater 105 for heating the bathroom mainly by convection heat, and a radiant heater for heating the bathroom mainly by radiant heat. 106, a louver 107 covering the opening of the bathroom, an adapter 109 connected to the duct 108, an operation designation unit 110 for designating an operation mode of "ventilation", "heating", and "drying". The circulation fan 102, the ventilation fan 104,
The ventilation dryer 112 for a bathroom was constituted by the control unit 111 that controls the convection heater 105 and the radiation heater 106.

In the above configuration, when the "ventilation" operation is designated by the operation designation unit 110, the ventilation fan 104 is operated by the control unit 111 to ventilate the bathroom.

[0006] When the “heating” operation is designated by the operation designation unit 110, the circulation fan 10 is controlled by the control unit 111.
2 and the radiation heater 106 operated to heat the bathroom.

[0007] Then, "dry" is performed by the operation designation unit 110.
When the operation is designated, the control unit 111 controls the circulation fan 1.
02, the ventilation fan 104 and the convection heater 105 were operated to dry the bathroom.

[0008]

In such a configuration of the conventional bathroom ventilation dryer, when the "heating" operation is designated by the operation designation unit 110, the radiant heater 106 heats the air in the bathroom. The circulation fan 102 spreads warm air throughout the bathroom. However, heating by radiant heat does not raise the temperature of the air itself in the bathroom so much and the heating efficiency is small. When there is no bather, there is a problem that the heating effect is small.

In the “heating” operation, the circulation fan 10
When the bath 2 is operated, a wind is generated. In winter, when there is a bather in the washing place, the bather has a problem that the bather feels cold.

[0010] The present invention solves the above-mentioned problems, and is intended for a bathroom capable of performing "heating" operation with high heating efficiency even when there is no bather in the washing area, such as when the bathroom is warmed before bathing. First to provide ventilation dryer
The purpose of.

A second object is to perform a "heating" operation in which a bather does not feel cold due to the wind.

A third object is to heat and ventilate the bathroom reflecting the bather's intention.

[0013]

According to the ventilation drier for bathroom of the present invention, when the operation designating section designates heating of the bathroom, the human body detecting sensor detects the presence of a person in the washing room in the bathroom. Is controlled by the control unit to heat the bathroom with a radiant heater, and when the human body detection sensor does not detect the presence of a person in the washing room in the bathroom, the control unit controls the bathroom to be heated by the convection heater. It is configured.

According to the present invention, there is provided a ventilation dryer for a bathroom which can perform a "heating" operation having a high heating efficiency even when there is no bather in the washing area, for example, when the bathroom is pre-warmed before taking a bath. Can be provided.

[0015]
