Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier for controlling humidification of a room.

[0002]

2. Description of the Related Art In a conventional general humidifier, a humidifier body 51 is provided with a water tank 52 and a heating tank 53 as shown in FIG.
The water supply tank 55 is configured to be detachably detachable from the water tank 52. In such a humidifier, the water in the heating tank 53 is heated by the heater to evaporate, and the water vapor is discharged to the outside through the discharge port 58 a of the discharge case 58. Then, the water level of the water tank 52 drops, and the water surface becomes the tank cap 5.
When the temperature falls below 5a, the air enters the water supply tank 55 through the opening of the tank cap 55a, and instead, the same volume of water comes out of the water supply tank 55, and the heating tank 53 passes through the U-shaped communication pipe 54 from the water tank 52. Supplied to the side. In this way, water is replenished from the water supply tank 55 at any time by the reduced amount of water evaporated by the heating tank 53.

[0003]

However, in the conventional humidifier described above, when water is heated and evaporated in the heating tank, and water in the water supply tank is sequentially supplied to the heating tank and evaporates, the heating is performed. In the residual water in the tank, scale components such as calcium, which are often contained in tap water and the like, stick to the inner surface and the bottom surface of the heating tank. The adhesion of the scale component deteriorates the heating efficiency, and further causes a problem such as impeding water passage by adhering to the inside of the U-shaped communication pipe, thereby making it impossible to use the scale component.

The present invention solves the above-mentioned problems of the prior art, and provides a humidifier which has a simple structure, is easy to clean even if scale components adhere thereto, and has a high heating efficiency in a heating tank. It is an object.

[0005]

Means for Solving the Problems A first means of the humidifier according to the present invention for solving the above-mentioned problems comprises a water tank provided in a main body, a water supply tank for supplying water while keeping the water level of the water tank constant, and a heat generating tank. A heating tank equipped with a body to heat water, a steam case that stands on the heating tank and emits steam outside the main body, a water passage provided between the water tank and the heating tank, and a water tank provided in the water passage. A concave portion provided lower than the bottom surface, and a first heat shield portion and a second heat shield portion having an opening in a water passage are integrally and detachably disposed, and one of the first heat shield portion and the second heat shield portion is provided. Is configured to be mounted on the recess.

The second means has a structure in which the first heat shield and the second heat shield are provided integrally with the steam case.

The third means includes a water tank provided in the main body,
A water supply tank that supplies water while keeping the water level of the water tank constant, a heating tank that has a heating element and heats the water, a steam case that stands on the heating tank and emits steam outside the main body, and a water tank and a heating tank In this configuration, a water passage provided therebetween and a heat shield having a heat shield space for blocking heat from the heating tank are detachably provided in the water passage.

Since the heat shield and the second heat shield can also be easily cleaned, problems such as obstructing water flow between the heating tank and the water tank can be prevented.

Further, according to the structure of the second means, by integrating the first heat shield and the second heat shield with the steam case,
The number of parts can be reduced, the first heat shield and the second heat shield can be separated from the water passage along with the steam case, and scale components such as calcium adhered to the water passage can be easily cleaned. And the detached first heat shield, second heat shield and steam case can be easily cleaned, so that troubles such as obstructing water flow between the heating tank and the water tank do not occur. Can be.

[0010] Further, according to the configuration of the third means, a heat shield portion having a heat shield space for blocking the heat of the heating tank is detachably provided in the water passage, so that the hot water in the heating tank does not easily flow into the water tank side. An air layer having a lower thermal conductivity can further suppress a rise in the water temperature of the water tank. Since the heat shield can be separated from the water passage, scale components such as calcium adhered to the water passage can be easily cleaned, and the separated heat shield can be easily cleaned. It is possible to prevent problems such as obstructing the flow of water between them.
