Description

Description: TECHNICAL FIELD The present invention relates to a humidifier for supplying moisture to dry air in a room or a refrigerator to increase the humidity.

[Conventional technology]

Recent living spaces are becoming more heat-insulating and airtight from the viewpoint of energy saving, and higher air conditioning is required. Elements of air conditioning include temperature control, humidity control, and control of harmful air components. Among these, various satisfactory heating and cooling systems have been put into practical use. However, regarding humidity control and control of harmful components, a sufficiently satisfactory device has not been proposed yet. In particular, humidifiers that control humidity include natural evaporation type, electric heating type, water spray type, ultrasonic type, etc. However, the natural evaporation type has a small humidification capacity, and the electric heating type has disadvantages that running costs are high. Also, the water spray type has a problem that the humidification efficiency is poor and the size becomes large.
The ultrasonic method is troublesome to maintain and has the drawback that fine powder of calcium carbonate is scattered.

Of these methods, the natural evaporation type humidifier has the lowest initial cost and running cost, and the highest practicality such as no scattering of calcium carbonate fine powder. Fig. 2 shows the structure of the components. In this figure, (1) is, for example, JP-A-60
-171337 is a hollow porous member, a sheet member formed of a hydrophobic polymer porous sheet as a main material is formed into a bag shape so that water vapor can pass through the inside and outside thereof. Has been Specifically, for example, a sheet made of synthetic resin such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polyester, and fluorine resin, which is configured to block the passage of water and allow the passage of water vapor. And a breathable fabric made of a woven fabric such as a plant fiber or a chemical fiber. Moreover, since the sheet and the breathable cloth have their pores closed when they are entirely bonded,
For example, partial spot joining at intervals of about 5 to 10 mm facilitates the passage of water vapor. (2) is a water supply port for supplying water into the hollow porous member, (3) is a spacing member housed in the hollow porous member, and has hollow porosity at both sides and the center of the hollow porous member. It is composed of a cylindrical part (3A) extending in the longitudinal direction of the elastic member and a thin plate part (3B) connecting the cylindrical parts. The cylindrical part (3A) allows the hollow porous members to adhere to each other. And a sufficient space is ensured in the hollow porous member, and a water channel is formed between the thin plate portion (3B) and the hollow porous member. A highly flexible vinyl chloride resin, silicone resin, or the like is used as a constituent material of the spacing member, and is manufactured by extrusion molding. Although not shown in the figure, a drainage port for draining the internal water is provided at the left end in the figure of the hollow porous member (1). This drain port is closed in normal use, and is used to drain water when the humidifier is not used for a long time. The hollow porous member (1) described above is wound in a spiral shape as shown in FIG. 3 to form a humidifier. That is, the hollow porous member (1) is wound into a honeycomb columnar shape via a corrugated separator (4) made of, for example, plastic, and a water supply connected to a water supply port (2) is provided above it. A water supply tank (6) for supplying water for evaporation through the pipe (5) and the water supply pipe is provided. The arrow (A) in the figure indicates the water supply direction, (B) indicates the air introduction direction, and (C) indicates the air discharge direction.

[Problems to be Solved by the Invention]

Since the conventional humidifier is configured as described above,
As shown in the figure, which is a characteristic diagram of the humidification amount and the air temperature or the water temperature flowing in the hollow porous member, the humidification amount depends on the supplied air temperature or the water temperature flowing in the hollow porous member (1). Changes significantly. For this reason, when the temperature of the supplied air is low, such as when used in a refrigerator or a cold work place, a hollow porous member (1) having a large surface area is required to obtain the required amount of humidification. In addition, it is possible to freely control the amount of humidification by adjusting the temperature of the air to be supplied, but in this case the equipment becomes bulky, and if heated air is supplied, the temperature inside the refrigerator will rise. There was a problem such as being lost.

The present invention has been made in order to solve the above-mentioned problems, and it requires only a small surface area of the hollow porous member, and increases the amount of humidification without increasing the size of the device, and it is optional. It is intended to provide a humidifier that can be controlled.

[Means for Solving the Problems]

In the humidifier according to the present invention, the spacing member is composed of an electric heating element, and an electric power adjuster for adjusting the electric power supplied to the electric heating element is provided.

[Action]

The humidifier according to the present invention is easy to assemble and
When the temperature of the supplied air is low, the temperature of the electric heating element can be raised to raise the temperature of the water flowing in the water channel to obtain a sufficient amount of humidification, and the temperature of the electric heating element can be adjusted. By doing so, the amount of humidification can be adjusted freely.

Example of Invention

An embodiment of the present invention will be described below with reference to FIG.
In this figure, (7) is a spacing member, which is a prismatic spacer (7A) extending in the longitudinal direction of the hollow porous member at both sides and the central portion of the hollow porous member (1) and a flat plate portion (7B) between the spacers. ) And the flat plate portion (7B) is formed by a planar heating element in which a conductive filler is dispersed in a matrix material. Further, electrodes (8) such as copper wires for supplying power to the planar electric heating element (7B) are embedded in the spacers (7A) on both sides. Reference numeral (9) is a lead wire connected to the electrode (8), which extends through the hollow porous member (1) to the outside. (10) is a power adjuster connected to the lead wire (9), and is provided with an adjusting knob (11) for adjusting the power supplied to the planar electric heating element (7B). The other structure is similar to that of the conventional device, and thus the description thereof is omitted.

In such a configuration, the amount of humidification can be increased by increasing the power supplied to the planar electric heating element (7B) and increasing the temperature of the water flowing in the hollow porous member (1). However, the method of directly heating water in this way is
It has been confirmed that the same effect can be achieved with far less energy than the conventional method of indirectly increasing the amount of humidification by heating air. In addition, by controlling the power supplied to the planar electric heating element (7B) with the power regulator (10), the water temperature can be freely changed in a short time, and the amount of humidification can be controlled accurately. is there.

〔The invention's effect〕

As described above, according to the present invention, since the spacing member is composed of the electric heating element and the power regulator for adjusting the power supplied to the heating element is provided, sufficient humidification is achieved even in a low temperature atmosphere such as in a refrigerator. The amount of humidification can be obtained, and the amount of humidification can be arbitrarily adjusted without using a large-scale device as in the case of the air heating system. Furthermore, since heat transfer to a low temperature atmosphere such as in a refrigerator is due to heat transfer from a humidifier, the load may be relatively small, and the temperature of the low temperature atmosphere may rise. Absent.
