Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a humidifier that adjusts indoor humidification.
[0002]
[Prior art]
Conventionally, this type of humidifier is generally configured as shown in FIG. The configuration will be described below with reference to FIG.
[0003]
As shown in the drawing, the bottom surface of the humidifying tray 102 provided in the main body 101 and the bottom surface of the water tank 103 are connected by a pipe 104. Water is supplied to the water tank 103 and the humidifying tray 102 at a constant water level by a tank 105 installed at the upper part of the water tank 103. The water level detection float 106 provided in the water tank 103 stops energization of the heating element 107 fixed around the humidifying tray when the water level drops. The fan motor 108 sends water vapor generated from the humidifying tray 102 from the main body 101 to the room through the steam guide tube 109.
[0004]
In the above configuration, the steam supplied from the tank 105 to the humidifying tray 102 through the water tank 103 and the pipe 104 and heated by the heating element 107 passes through the steam guide tube 109 and is blown into the room together with the air from the fan motor 108.
[0005]
A humidifier described in JP-A-7-324784 is known. That is, as shown in FIG. 7, by attaching the water discharge means 111 inserted into the water tank 110 to the steam guide tube 112, the water capacity in the water tank 110 is reduced, the generation of water vapor is accelerated, and the humidifier starts up. The time can be shortened.
[0006]
[Problems to be solved by the invention]
In such a conventional humidifier, impurities such as magnesium and calcium gradually adhere to the side of the humidifying dish and the pipe by heating the tap water, so it is necessary to periodically clean the humidifying dish. It is difficult to remove impurities adhering to the wall surface and pipe of the humidifying dish, and a structure that is easy to clean is required.
[0007]
Moreover, since the heating element is fixed to the side periphery of the humidifying dish, heat is radiated not only to the contact surface of the humidifying dish but also to the opposite side of the humidifying dish, and the heat quantity of the heating element is not effectively used. In some cases, a humidification method with high heating efficiency is required.
[0008]
This invention solves such a conventional subject, and it is easy to clean a humidification dish and it aims at providing the humidifier with high heating efficiency which suppressed the radiation | emission of the heat | fever.
[0009]
In addition, with conventional humidifiers, the temperature rises by heating the water that has reached a predetermined water level in the humidifying pan, so the rise time until evaporation starts may be longer. Is required to be able to start.
[0010]
This invention solves such a conventional subject, and it aims at providing the humidifier which can start humidification operation in a short time.
[0011]
In addition, in conventional humidifiers, water in the water supply tank is jetted from the bottom of the humidifying tray to maintain a constant water level, so mixing with hot water lowers the water temperature in the humidifying tray and makes humidification unstable. In addition, when the water temperature rises again, noise generated in the process of boiling may occur periodically several times, and it is required to keep the humidification amount constant and to operate with low noise.
[0012]
The present invention solves such a conventional problem, and an object of the present invention is to provide a humidifier capable of operating with low noise while maintaining a constant steam generation amount.
[0013]
Further, in the conventional humidifier shown in FIG. 7, the water discharge means 111 is attached to the steam guide tube 112. Therefore, the structure becomes complicated, the number of parts and the number of assembly steps increase, and the steam guide tube 112 is attached to the main body. Due to the buoyancy of the water discharge means 111, the mounting workability may not be good, and the mounting work of the steam guide tube 112 is required to be easy without increasing the number of parts.
[0014]
SUMMARY OF THE INVENTION The present invention solves such a conventional problem, and an object thereof is to provide a humidifier having a simple structure, a small number of parts, easy installation of a steam guide tube and a short operation start-up time.
[0015]
In addition, in the conventional humidifier, the heater heat fixed to the humidifying tray may diffuse through the components of the main body via the humidifying tray, and the heat of the heating element diffuses to the surroundings and is not lost. It is requested.
[0016]
The present invention solves such a conventional problem, and an object of the present invention is to provide a humidifier in which the heat of the heating element does not diffuse around.
[0017]
[Means for Solving the Problems]
One means of the humidifier of the present invention for solving the above problems is a water tank provided in the main body, a water supply tank for supplying water while keeping the water level of the water tank constant, and heat dissipation provided to protrude from the bottom surface of the water tank. Body, a heating element provided inside the radiator, and a heat diffusion prevention cylinder standing upright from the water surface around the radiator, and the top surface portion of the radiator is provided below the water surface. The surface portion is formed in a substantially flat plate shape, and a heating element is closely attached to the back side of the top surface portion .
[0018]
And by the means according to the present invention, by suppressing the radiation of heat of the heating element to increase the heating efficiency, clean the humidifying dish ease rather, humidifier is obtained which can initiate humidifying operation in a short time.
[0019]
Another means is that an opening is provided on the side surface of the heat diffusion prevention cylinder, the opening is arranged below the top surface of the radiator , and a fan is provided from the discharge port provided at the upper end of the heat diffusion prevention cylinder. The steam is discharged out of the main body together with the air from the motor .
[0020]
According to the present invention, the above-mentioned means can provide a humidifier that can keep the steam generation amount steady, can be operated with low noise, has a small number of parts, is easy to install the steam guide tube, and has a short operation start-up time .
[0021]
DETAILED DESCRIPTION OF THE INVENTION
