The present invention relates to a humidifier capable of rapidly humidifying.

As a conventional method of humidifying air, there are a method of heating and evaporating water in an open container with a heating element, and a method of applying ultrasonic waves to water to scatter fine water droplets in the air and evaporating the water droplets.

The former method requires a long time to start evaporation after heating in order to heat the entire amount of water in the container and evaporate it from the surface, whether by electric resistance heating or other heating methods, and to stop evaporation to stop evaporation. The evaporation of water does not stop immediately, and the control of minute humidity in the air is impossible.

In the latter method, the droplets scattered by the ultrasonic wave may form dew on the inner surface of the duct due to different evaporation rates in the air, and it is difficult to precisely control the humidity of the air stream, and also by the ultrasonic wave. When water droplets form dew in the ducts, there is a deadly bond in which bacteria multiply and enter the air.

The present invention floats a surface heating element in a stationary water surface, adjusts the buoyancy so that water is filled in a thickness of 1 to several mm on the upper surface of the surface heating element, and the surface shape by adjusting the heat generation amount of the surface heating element It is a rapid humidification responsive float type humidification device that regulates the humidity of the air by intermittently evaporating a small amount of water on the upper surface of the phosphorus heating element for a short time, eliminating the drawbacks of the conventional method, and controlling the humidification quickly and precisely. It is possible to obtain a humidification method that does not consume waste heat energy.

Example 1

As shown in FIG. 1 and FIG. 3, side edges 2, 3, 4, and 5 are erected around the surface-shaped heating element 1, and side edges 2 and 4 facing each other. Cutouts (6), (6). On the outer surface of the side surfaces (3) and (5), and attaching the floats (7) and (7) made of a material such as a hollow cylinder and a synthetic resin foam, and attaching them to the resistance line 8 of the planar heating element 1. The lead wires 9 and 9 are connected to float on the stationary water surface 10, and the top surface of the planar heating element 1 is made to have a thin layer of water 11 having a depth of 1 mm to several mm. It is a rapid humidification responsive prout humidifier by adjusting the buoyancy of the float to fill.

Example 2

As shown in FIG. 2 and FIG. 3, the heat insulating material 12 is attached to the lower surface of the heat generating element 1 which is planar shape of Example 1, and the heat generating line 1 of the planar heating element is connected to a power supply, or 4th As shown in the figure, the pipes 8a are arranged in an S-shape, intermittently allowing high-temperature fluids, such as gas, water vapor, etc. to flow intermittently in the direction of the arrow shown, to float on the stationary water surface 10, and to form a plane It is a rapid humidification responsive float type humidification device made by adjusting the buoyancy of the float (7) so that the top surface of the phosphorescent heating element (1) is filled with a thin layer of water (10 mm to several mm in depth) is stabilized.

When the heat insulating material 12 fully holds buoyancy, the heat insulating material 12 may be used as a float, and the float 7 may be abbreviate | omitted.

Example 3

As shown in FIG. 6, the sidewalls 13, 13. To cutouts 6, 6 of constant depth. Or holes 6a, 6a... The heat generating element 1 having a planar shape is fixed in the tray 14 provided with the side surface 13, 13. To four corners of the float 7a, 7a... As shown in FIG. 5, the heat insulating material 12 is mounted on the bottom surface of the tray 14 and floated in the water in the container 15. In this case, the buoyancy of the float is adjusted to adjust the surface of the heating element ( It is a rapid humidification responsive prout humidification apparatus in which the upper surface of 1) is filled with a thin layer of water 11 having a depth of 1 mm to several mm.

The heat insulator may attach the heat insulator 12a to the side wall 13, for example the entire circumference, as shown in FIG. 6 in addition to the heat insulator 12 mounted on the underside of the tray 14.

In addition, when the water in the container 15 is reduced by evaporation, it is necessary to replenish water by, for example, the pipe 16 or the like. In this case, the float switch 17 is used, for example, the height of the predetermined position 17a. It is convenient to make water supply automatically when it descends to and stop water supply when the height rises to the predetermined position 17. FIG.

In Example 1 to Example 3, an example of using a rectangular planar heating element 1 has been described. However, as shown in FIG. 7, for example, a circular planar heating element 1a and a round annular float ( 7b) and (7b) can also be used.

In use, when electricity or high-temperature gas and steam flow into the planar heating element 1, a thin layer of water 11 having a depth of 1 mm to several mm filled in the upper surface of the planar heating element 1 evaporates immediately. By generating high-humidity air on the surface of the water and stopping the flow of electricity or hot gas and vapor, the evaporation of water is stopped immediately, the air humidity on the water surface is lowered, and the controlled humidity is quickly performed.

As an example, a method of maintaining a constant humidity in a room may be described. As shown in FIG. 8, a pattern in which a heating element 1, a float 7, and a heat insulating material 12 are floated on the water surface 10. The container 5 of the float type humidifier of the present invention is sealed, and the air on the water surface 10 and the outside air 18 are mixed by a duct and sent to the chamber 19 for controlling humidity, and the open end of the feeding duct Humidity sensor 20 is installed on the surface of the heating element (1), the control box 21, the humidity sensor 20 and the power supply line (9) connected to the lead wire (9), the humidity by the humidity sensor 20 It sends this signal to the control box 21 and generates heat intermittently the planar heating element 1 according to the fluctuation of the minute humidity in the chamber 19, so that the amount of evaporation of water is accommodated within a predetermined relative humidity range. Adjust Reference numeral 22 is exhaust.

In addition, in the present invention, an atmosphere containing a vapor of a volatile liquid at a constant concentration, that is, a constant vapor pressure, is formed by using a solvent such as an organic solvent or other volatile liquid instead of water, and by chemical reaction, pesticide, etc. in the vapor phase. Can be used.

Since the present invention is constructed as described above, the upper surface of the planar heating element 1 always maintains a wide layer of water 11 having a depth of 1 mm to several mm, and the water of the portion has a very small heat capacity, so It evaporates in a very short time after the inflow of high temperature gas or steam, and responds to the interruption of energization or high temperature gas and steam inflow rapidly to regulate the evaporation of water, and the air to be controlled humidity of humidity is obtained very quickly. The relative humidity can be accurately controlled and maintained with an error of about ± 1%.

In this case, a thin layer of water 11 is boiled vigorously, so it is better to avoid water droplets.

Although it takes about 10 minutes to sink a 1 kW plane heating element (length 170 mm, width 120 mm, thickness 2.5 mm) on the bottom of the container containing 1 liter of water and heat the water from 20 ° C to 100 ° C. Float type humidifier is floated in 1 liter of water, and the thin layer of water 11 on the upper surface of the heating element 1 (same size as above) having a surface shape of 1 kW has a depth of 3 mm. It takes about 30 seconds to heat this 20 degreeC to 100 degreeC.

9 shows this comparison, where curve A is a temperature rise of a thin layer of water 11 on the upper surface of the heating element 1, which is a planar shape of the float type humidifier of the present invention, and curve B is a temperature rise of water according to a conventional method. Is displayed.

Moreover, when installing the layer of the heat insulating material 12 in the lower surface of the planar heating element 1, most of the heat energy emitted by the planar heating element 1 is consumed only by heating the thin layer of water 11, There is little thermal energy used for heating a large amount of water, and the temperature rise of the water in the capacity 15 is small, and thus energy is saved because the release of heat from the outer periphery of the container is extremely small.
