Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bath ventilation dryer capable of exhausting moisture in a bathroom and drying an object to be dried such as a laundry suspended in the bathroom or heating the bathroom.
[0002]
[Prior art]
In recent years, as the number of bathrooms installed in general households has increased, bath ventilation dryers having a drying function for drying laundry using the bathroom have become widespread.
[0003]
Conventionally, what was shown by FIGS. 12-14 was developed as an example of this kind of bath ventilation dryer. Hereinafter, the configuration will be described with reference to FIGS.
[0004]
As shown in the figure, it is a box installed on the ceiling surface of the bathroom 101 and has an exhaust port 102 communicating with the outdoors on the side surface, and a ventilation suction port 103, a circulation suction port 104, and a blowout port on the lower surface. A main body 106 is provided, and a ventilation fan 107 is provided in an air flow path that connects the ventilation inlet 103 and the exhaust 102 of the main body 106, and an air flow that connects the circulation inlet 104 and the outlet 105. A circulation fan 108 is provided in the road, and a blowout airflow of the circulation fan 108 is blown from an oblique direction so as to flow in the longitudinal direction of the blowout port 105 and is blown into the bathroom 1011 from the blowout port 105. The blowout port 105 is provided with a halogen heater 110 provided with a reflector 109 so as to emit heat toward the bathroom 101.
[0005]
[Problems to be solved by the invention]
According to such a conventional bath ventilation dryer, the direction of the air blown into the bathroom 101 from the blowout port 105 is deflected in the blowout direction of air blown from the circulation fan 108 toward the blowout port 105. As a result, there is a problem that the blowing air speed and temperature are not uniform, and the clothes drying time is prolonged.
[0006]
Further, the halogen heater 109 encloses a trace amount of halogen element together with an inert gas in the tube, and causes a halogen cycle in which tungsten evaporated in the tube is returned to the original filament by making the temperature conditions appropriate. The evaporated tungsten moves to a relatively low temperature while floating in an inert gas, where the halogen and tungsten combine to form tungsten halide, which becomes a substance that is very easy to evaporate, and the inside of the tube is 250 ° C. or higher. If so, keep the gas state without precipitation, keep floating in the tube, and when this gaseous tungsten halide approaches the filament, the temperature rises to 1500-2000 ° C, and the halogen and tungsten are separated due to the high temperature. Tungsten again adheres to the filament.
[0007]
On the other hand, the separated halogen combines with the evaporated tungsten again to form a halogen cycle.
[0008]
Therefore, when the temperature of the tube surface of the halogen heater 109 becomes non-uniform, the temperature of the halogen gas sealed inside the tube also becomes non-uniform, and the halogen cycle is less likely to occur uniformly on the tube surface. In addition, there is a problem that the life of the halogen heater 109 is shortened because the temperature becomes partly too low, the halogen cycle does not occur, the oxidation of the filament proceeds partially, and the life of the filament is shortened. .
[0009]
Further, since the wind does not reach the entire tube of the halogen heater 109 sufficiently, the heat of the halogen heater 109 cannot be fully utilized, and there is a problem that the thermal efficiency is poor.
[0010]
In addition, the halogen heater 109 has a high filament temperature and a large amount of radiant heat, but has a high luminance. Especially, a person who has entered the bathtub 111 may relax and look up at the ceiling, and at that time, a strong feeling of glare is felt. There was a problem of making the bather uncomfortable.
[0011]
An object of the present invention is to solve the above-mentioned problems, and to provide a bath ventilation dryer that can shorten the drying time of clothes and improve thermal efficiency and does not give a feeling of glare to a bather. And
[0012]
[Means for Solving the Problems]
