Description

[Detailed Description of the Invention] The purpose of the present invention is to improve conventional heaters especially for heating and ventilation in bathrooms and the like.

Conventional heaters such as electric stoves generally use heaters made of heat-resistant glass tubes because of their quick heating start-up and cost, but these types of heaters do not have their current-carrying and heat-generating parts sealed. Therefore, there are problems with the lifespan and safety of the heater when it is installed in a bathroom or the like where the humidity is always high.

Therefore, the present invention provides a bathroom heater that can be combined with a fan and shutter to prevent steam from being applied to the energized parts of the heater and at the same time improve the heating effect.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a sectional view of an entire bathroom equipped with a heater according to the invention. 1 is a bathroom, 2 is a bathtub, 3 is a door at the bathroom entrance, and a hot air heater 4 for the bathroom is installed in a storage section 5 provided at the upper part of the side wall of the bathroom.

Figure 2 shows an enlarged sectional view of the hot air heater. A fan 7 and an electric heater 8 are provided inside the main body 6, and shutters 11 and 12 are provided at the air intake 9 and air outlet 10, respectively. Fan 7 is a motor (not shown)
Driven by Reference numeral 13 denotes a shutter for opening and closing the ventilation passage from the fan to the heater section and at the same time for opening and closing the exhaust port 14 leading to the outside of the bathroom.

In the above configuration, shutters 11, 12 and 1
3 is opened and the fan and heater are activated (the state shown in Figure 1), the air sucked in from the air intake port 9 is warmed by the heater 8 and then returned to the bathroom from the outlet port 10. , warm the bathroom. When the heater is turned off and only the fan operates, only the shutter 11 opens (as shown in Figure 2), sucking the humid air in the bathroom through the air intake port 9 and exhausting it outside through the exhaust port 14. to remove moisture in the bathroom.

Since both shutters 11 and 12 are closed when neither the fan nor the heater is operating, moist air will not enter the live parts of the motor or heater and deteriorate the insulation.

Since the shutter 11 has a structure that opens toward the air outlet 10 side, when it is open, it acts as a guide to regulate the flow of air being sucked in and air being expelled, and the expelled air can be taken in immediately. Prevents being sucked in from the mouth 9. Also, immediately after the heater and fan are turned on, while the temperature of the heater is low, we want to prevent cold air from flowing into the bathroom, and at the same time, while the temperature of the heater is low, moist air can cause insulation failure in the heater's live part. In order to prevent this from happening, it is best to use a combination of temperature switches and electromagnets to prevent all shutters from opening until the heater reaches a certain temperature.

As explained above, according to the present invention, it is possible to safely heat a humid bathroom with a simple structure, and it is convenient and reliable as it increases the heating effect by sending hot air and at the same time ventilates the room. It is possible to provide a hot air heater with high temperature.

Claims (1)

[Scope of claims for utility model registration] (1) Heater, fan, air outlet,
It has an intake port and a shutter provided in the ventilation path of the fan, and the heater and shutter are arranged between the air outlet and the fan in the order of fan → shutter → heater → exhaust port, The hot air heater for a bathroom is characterized in that when the heater is turned off, the shutter blocks an air passage from the fan to the heater and at the same time opens an air passage to the outside of the bathroom. (2) A second shutter is installed at the air outlet and a third shutter is installed at the air intake. When the fan and heater operate at the same time, both shutters open, and when only the fan operates, the third shutter opens. The hot air heater for a bathroom according to claim 1 of the utility model registration claim, characterized in that only the opening can be opened. (3) The hot air heater for a bathroom as set forth in claim 1 of the utility model registration claim, characterized in that when the fan and heater are activated, all shutters are not opened until the ambient temperature of the heater rises to a certain temperature. (4) The hot air heater for a bathroom according to claim 1, wherein the third shutter has a structure that opens toward the air outlet side.
