Abstract

PURPOSE:To control an evaporation area of water and further to control a humidifying capability by a method wherein a plurality of water supplying tanks and a controlling member for use in controlling an amount of supplied water for the water supplying tanks are provided, and the number of humidifying elements to be immersed in water are divided. CONSTITUTION:Humidifying elements 3 are made of hydrophilic plastic material having a moisture absorptive characteristic and lower portions of the two humidifying elements are stored in water supplying tanks 5a and 5b, respectively. A controller member 4 for use in controlling the amount of supplying water to each of the water supplying tanks 5a to 5b is comprised of water supplying pipes 6a and 6b opened into each of the water supplying tanks 5a and 5b and solenoid valves 7a and 7b arranged in each of the water supplying pipes. One end 8 is connected to a tap water pipe. As the solenoid valves 7a to 7b are operated, water is supplied to the water supplying tanks 5a and 5b, the lower ends of all the humidifying elements 3 are immersed in the water, the water is sucked up and then the elements are wetted. Air blown from the direction (a) under operation of the air blower is contacted with the water sucked by the humidifying elements 3, humidified by the water and flows in the direction (b). As only the solenoid 7a is operated, water is supplied only to the first water supplying tank 5a. As the solenoid valve to be operated is optionally determined to enable a humidifying capability to be controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a humidifier that is incorporated into air conditioning equipment and the like.

BACKGROUND OF THE INVENTION In recent years, as air conditioning equipment has become more sophisticated, the demand for humidifiers has rapidly increased, and there has been a strong demand for improved humidification controllability.

As a conventional technique, for example, Utility Model Application No. 62-1054c1
There is a humidifier as shown in Publication No. 6.

An example of the conventional humidifier mentioned above will be described below with reference to the drawings.

FIG. 2 shows a perspective view of a conventional humidifier.

Reference numeral 1 denotes a humidifying element formed of a hydrophilic porous sintered body made of polyolefin resin or the like, and a plurality of humidifying elements are arranged so as to maintain intervals. 2 is one water supply tank, and water is supplied by a solenoid valve or the like. Also, A indicates the direction in which dry air enters before humidification, and the mouth indicates the direction in which humidified air exits.

The operation of the humidifier configured as above will be described below.

One end of the humidifying element 1 is immersed in water supplied to a water tank 2. Since the humidifying element 1 is formed of a hydrophilic porous sintered body, water is absorbed into its pores due to capillary action, and the entire element becomes wet. When dry air is blown from the direction A by a blower installed in an air conditioner, the air comes into contact with the water absorbed by the humidifying element, evaporates, and is humidified before exiting from the mouth. go.

Problems to be Solved by the Invention However, in the above configuration, since there is only one water supply tank, when water is supplied, all of the plurality of humidifying elements are immersed in water at the same time, resulting in a constant humidifying capacity. The problem was that it was impossible to adjust the temperature according to the drying condition of the room.

In view of the above-mentioned problems, the present invention provides a humidifier that can freely and easily control its humidifying capacity and can realize an optimal humidifying state depending on the dryness of the room.

Means for Solving the Problems In order to solve the above problems, a humidifier of the present invention includes a plurality of water tanks and a control body for controlling the amount of water supplied to the water tank.

Function According to the present invention, by dividing the number of humidifying elements to be immersed in water, the evaporation area of water can be controlled and the humidifying capacity can be controlled.

EXAMPLE Hereinafter, a humidifier according to an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a perspective view of a humidifier in one embodiment of the present invention. 3 is a humidifying element formed of a hydrophilic porous sintered body made of polyolefin resin or the like. s
a and sb are a first water tank, a second water tank, and a second water tank,
The lower portions of two humidifying elements are housed in the first water tank 5a and the second water tank 6b, respectively. 4 is a control body that controls the amount of water supplied to each of the water tanks 6a to 6b; The water supply pipe 6b includes a first solenoid valve 7a and a second solenoid valve 7b provided in each water supply pipe. Further, one end 8 of the control body 4 is connected to a water source such as a tank or water supply.

Also, A represents the direction in which dry air before humidification flows in, and the mouth represents the direction in which humidified air flows out.

The operation of the humidifier configured as described above will be explained below using FIG. 1.

When the solenoid valves 7a to 7b are operated during humidification operation,
Water enters one end from a water source, passes through electromagnetic valves 7a to 7b, and is supplied to water tanks 6a to 6b, so that the lower ends of all humidifying elements 3 are immersed in water. Since the humidifying element is a hydrophilic porous sintered body, water is absorbed into its pores by capillary action, and the humidifying element 3 becomes wet. The dry air blown from the A direction by a blower installed in an air conditioner or the like comes into contact with the water absorbed by the humidifying element 3, evaporates the water, and the air is humidified and exits toward the mouth.

Further, when only the electromagnetic valve 7a is operated, water is supplied only to the first water supply tank 6a, and 3.2 humidifying elements in the water supply tank 6a are immersed in water and humidified in the same manner. In other words, the humidification capacity can be controlled by reducing the water evaporation area by half by arbitrarily deciding which solenoid valve to operate.

As described above, the humidifier of the present invention can control the humidifying capacity by including a plurality of water tanks and a control body that controls water supply to the water tanks.

Effects of the Invention As described above, the present invention enables humidification capacity to be easily controlled over a wide range by providing a plurality of water supply tanks and a control body for controlling water supply to the water supply tanks.
