JPH0571778A - Natural vaporization type humidifier - Google Patents

Abstract

PURPOSE:To provide a constant moistening amount regardless of temperature and humidity condition on which blast is effected by a natural vaporization type moistening device and to increase a moistening amount by a method wherein vaporization is easy to make by heating water for moistening sucked by means of a moistening element during heating operation by means of a ceramic heater. CONSTITUTION:A plurality of moistening sheets 4 produced such that a thin type ceramic heater 2 is nipped between moistening elements 1 are arranged in juxtaposition. The lower parts of the moistening sheets are immersed in a feed water box 5, and a ceramic heater 2 located thereabove is connected in series to a switch and a power source.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural evaporation type humidifier.

[0002]

2. Description of the Related Art Conventionally, in a natural evaporation type humidifier, as described in Japanese Patent Application Laid-Open No. 1-174836,
There is a method in which the lower end of a humidifying plate having a capillary phenomenon is immersed in humidifying water in a water tank, and the water sucked up by the humidifying plate is brought into contact with air for humidification.

[0003]

However, when the water sucked up by the humidifying plate in the above-mentioned prior art evaporates due to contact with the air, it depends largely on its temperature and humidity, and its humidifying ability cannot be obtained naturally. There was a fundamental drawback of the humidifier.

The present invention solves the above-mentioned conventional problems and provides a humidifier capable of obtaining a large humidification capacity regardless of the contacting air conditions.

[0005]

In order to achieve the above object, a natural evaporation type humidifier of the present invention comprises a humidifying element having a capillary phenomenon and a thin ceramic heater whose surface is coated with ceramic. The humidifying plate is formed by sandwiching the ceramic heater between the two humidifying elements, and a water supply box for immersing the lower parts of the plurality of humidifying plates.

[0006]

According to the present invention having the above-mentioned structure, the humidifying element immersed in the water in the water supply box absorbs the water by a capillary phenomenon, and the absorbed water is heated to a constant temperature by the ceramic heater, so that the humidifying plate is heated. It is possible to stably secure a constant amount of humidification regardless of the temperature and humidity conditions of the air contacting the.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a humidifying element made of non-woven fabric or the like, 2 is a thin ceramic heater whose surface is coated with ceramic, and has a lead wire 3 above it. The humidifying element 1 is sandwiched between the ceramic heaters 2 by adhesion or the like to form the humidifying plate 4.

In FIG. 2, a plurality of humidifying plates 4 are arranged side by side so as to be immersed in the humidifying water in the water supply box 5, and the respective ceramic heaters 2 of the plurality of humidifying plates 4 arranged in parallel are leads. A switch 6 and a power source 7 are connected in series by a line 3 to form a natural evaporation type humidifier 8.

The operation of the natural evaporation type humidifier 8 having the above structure will be described. By supplying the humidifying water to the water supply box 5 and immersing the lower part in the supplied humidifying water, the humidifying element 1 of the humidifying plate 4 sucks up the water. When the switch 6 connected to the ceramic heater 2 is turned on at the same time as the air is blown to the natural evaporation type humidifier 8, the ceramic heater 2 is warmed up by being connected to the power source 7 to be energized. Therefore, the humidifying element 1 of the humidifying plate 4
The water supplied to is also warmed, and the water sucked up by the blown air is evaporated and humidified.

As described above, according to this embodiment, the humidifying plate 4
By heating the ceramic heater 2 provided in the above, the water supplied to the humidification element 1 is easily evaporated, and the air blown to the natural evaporation type humidifier 8 is stable regardless of the temperature and humidity conditions. The amount of humidification can be secured.

[0012]

As described above, the natural evaporation type humidifier of the present invention forms a humidifying plate in which ceramic heaters are sandwiched by humidifying elements, a plurality of these are arranged in parallel, and the ceramic heaters are connected in series. Since the humidifying element absorbs the humidifying water supplied to the water supply box and the absorbed water is heated by the ceramic heater, the temperature of the air blown to this natural evaporative humidifier is However, it is possible to obtain a stable amount of humidification regardless of the humidity condition, and it is possible to eliminate the regulation that the natural evaporative humidifier can be installed only on the downstream side of the heat exchanger. effective.
