The present invention relates to a water supply automatic opening / closing heater type humidifier, and more particularly, it relates to a water supply automatic opening / closing heater humidifier which prevents the propagation of bacteria by discharging water vapor by heating the water accumulated below the water tank and accurately measuring the humidity of the room air, The present invention relates to a water supply automatic opening / closing heater type humidifier which improves the durability by simplifying the structure of the valve body.

Generally, a humidifier can be divided according to a method of generating moisture, and includes a heater humidifier for spraying water vapor generated by heating water stored in a water tank to a predetermined temperature into the room, and ultrasonic waves generated by vibrators in water stored in the water tank And an ultrasonic humidifier for spraying micronized water particles into the room.

In everyday life, most of the water vapor in the air that is sucked in during breathing is water vapor which is evaporated by solar heat, and the particles are very small and contain heat.

These atmospheric water vapor drops down to the ground as the temperature drops to dawn as the water vapor becomes thicker and becomes the dew point. In the ultrasonic humidifier used in the past, the water particles in the sprayed water are as thick as the particle size in the dew point water, It is blown up by the power of the wind by a fan and it comes out of the humidifier.

The water particles sprayed from the ultrasonic humidifier include various germs and foreign substances including minerals, so that they float on the dust floating in the room and then flow into the user's lungs during breathing.

These minerals and foreign substances are not introduced into human digestive organs but they are directly introduced into the lungs and cause various respiratory diseases.

In addition, coarse water vapor particles are absorbed by things such as evaporation and moisture absorbing fibers that fall into household tools and propagate bacteria to generate odors in the room.

Because of the problem of such ultrasonic humidifier, a heat sterilizing ultrasonic humidifier has been proposed. However, by heating the water using a heater, the propagation of the bacteria is slightly prevented. However, the temperature is slightly raised without boiling water to make the humidifier completely sterile Since the impurities including minerals are not removed, the disadvantages of the ultrasonic humidifier are maintained and the evaporated water particles are thick, which keeps the disadvantage of the ultrasonic humidifier.

A heater type humidifier is provided to solve the problems of the ultrasonic humidifier and the sterilizing ultrasonic humidifier.

Conventional heater-type humidifiers boil water and evaporate heat vapor only. There is no bacterial infection, no substance including mineral, and water vapor particles are very small and contain constant heat, so it is included in indoor air. .

However, since the conventional heater type humidifier continuously supplies water to the humidifier tank as the water evaporates, the cold water always mixes with the boiling water, and since the water can not be evaporated at a high temperature, There is a problem in that it can not satisfy a consumer's desire.

On the other hand, a small amount of water vapor which is emitted when water is boiled is reduced to the humidification tank due to the condensation phenomenon on the inner wall of the incinerator, which discharges water vapor before being discharged.

In order to solve the above problems, the present applicant has proposed a water supply automatic opening / closing heater type humidifier with patent registration No. 511366.

An anion tube is formed so as to be positioned above the evaporation tank, and water is introduced into the evaporation tank A water tank for forming a water supply pipe for supplying water to the water supply pipe and controlling the supply of water by interrupting the water supply pipe, a drive motor for contacting / separating the solenoid valve with the valve body, A motor drive relay for converting the output voltage into a DC voltage to forward / reverse the drive motor; and a switch drive circuit connected between the motor drive relay and the drive motor and driven by being mounted on the drive motor together with the solenoid valve First and second switches for controlling the amount of rotation of the switch driving plate by being turned on and off by the switch driving plate and a second switch connected between the overheat preventing bimetal and the power source, An overheat cut-off switch for blocking input to the power button, and a power source for driving the overheat cut-off switch) Is connected between the second transmitter and the former, the first Transformers and the solenoid valve that supplies to convert power from a group consisted of a resistance, which blocks the current.

However, in the conventional heater type humidifier as described above, even if the humidity is set, the humidity of the room can not be measured accurately, and the mechanical structure using the motor to drive the valve body for supplying water has a complicated structure, There is a problem that the user can not input the amount of water supplied to the evaporation tank and the operation of the humidifier can not be manually operated if there is a problem in the operation of the humidifier.
