Description

[Detailed Description of the Invention] [Industrial Application Field] Although this invention uses a single evaporation method using hot air, etc.,
J[] This relates to a constant humidifier with greatly improved humidification capacity.

[Conventional technology]

From the perspective of energy conservation, modern living spaces are becoming more insulated and airtight, and require air conditioning to a good degree.

Air conditioning elements include temperature control, humidity control, and control of harmful air components. With regard to temperature control, various heating and cooling methods are not in practical use, and progress is still being made. The situation is still lacking in terms of humidity control and control of harmful air components.

Regarding humidifiers, there are natural evaporation type, electric heating type, water spray type 2, ultrasonic type, etc. Natural evaporation type has a small humidifying capacity, electric heating type has a high running cost, and water spray type one type does not work. Humidification efficiency is low and the size is large. In addition, the ultrasonic method has drawbacks such as low initial cost and short life.

Therefore, we decided to consider a method to greatly improve the humidification capacity of a natural evaporation type humidifier, which has the lowest initial cost and running cost and is the least practical. In the natural evaporation method, in order to maximize the area for water evaporation, a vat-shaped container with a large opening is used, or the bottom end of a woven hydrophilic fiber is dipped in water to increase the surface area of the water using capillary force. are doing. If water were to be sliced to a thickness of ff mm and arranged in multiple layers vertically, the evaporation area of water could be greatly increased.

Therefore, as a result of repeated research on a method for vertically retaining water of the number of sliced thicknesses, we found that the above-mentioned It was previously discovered that water can be held in any space by containing the sliced water, and that the water can evaporate freely.

In order to commercialize the natural evaporation type humidifier 4 using the sheet of porous hydrophobic polymer material mentioned above, an aluminum plate or a plastic plate with a thickness of 5 mm was used to create a hollow space as shown in the perspective view of Fig. 5 (al). A humidifying element was prototyped by forming a frame of 100 to 200 μm thick porous notebook made of polyethylene or polypropylene material and pasting them together from both sides. V
c@ Full speed of air between the humidifying elements while watering, evaluation test of humidifying ability? went. However, is ill in the figure a frame? , (2) represents the water supply hole, and FIG. 5(b) represents a cross section near the center.

[Problem that the invention seeks to solve]

As a result, it was found that the above-mentioned porous sheet swells laterally due to its own weight of water, and when stacked, there is a problem in that the air passageway is greatly reduced.

Therefore, the inventors of the present invention conducted various studies, such as a method of pressing the porous sheet 82 with nets from both sides to prevent it from expanding laterally due to the weight of the water itself.As a result, the present invention was finally completed. . With this invention, a humidifier that does not expand laterally due to the water itself, increases the evaporation area of water, and increases the humidifying capacity. The purpose is to provide.

[Means for solving problems]

The humidifier of the present invention has a flow path unit in which a flow path formed of a porous hydrophobic polymer material capable of preventing the passage of water and allowing water vapor to pass through is partially internally joined, and the flow path Water is supplied into the flow path unit from a fourth part of the unit, and the air blown around the outer periphery of the flow path unit is humidified by being moistened with water vapor that has passed through the porous hydrophobic polymer material of the flow path unit. This is how it was done.

[Effect]

In this invention, the entire flow path for holding water for humidification is partially aligned with the inner Fil1, thereby preventing the water from expanding in the lateral direction due to its own weight. In addition, the suction bonding creates unevenness in the flow path, which increases the evaporation surface area of water, and furthermore, the air flow becomes turbulent, thereby increasing the humidification capacity.

[Ibun example]

This invention will be explained below based on the drawings. Figure 1 is an inkstone diagram showing a flow path unit according to the present invention. ) The gold in the figure shows the traces of internal heat fusion.

Two porous sheets measuring 320 x 220 mm were placed on top of each other and heat-sealed to form a bag, leaving 20 mm on each side as shown in Figure 1. Thereafter, a plurality of parallel and straight lines and maintenance thermal melting were performed at intervals of 10 mm, leaving 20 mm at each of the upper and lower ends. In the figure,
(2) represents the water supply and drainage outlet, outside? A 44 mm polyethylene tube was inserted as shown in the figure and adhered.

Fig. 2 (above 11F) is a perspective view showing an example of leprosy in a state in which it is firmly placed using the unit metal frame;
is a plastic plate with a thickness of 2 mm and a width of 20 mm.
Displays the entire frame including Ji. FIG. 2 (1) also shows a cross section near the center of the ridge. First, both sides of the channel unit shown in Fig. 1 were sandwiched between the plastic plates mentioned above and fixed using a dowel. Next, the above plastic plates were used to cover the non-heat-sealed parts of the upper and lower ends and were adhered as shown in the figure. At this time, is there air in the flow path z knit? I blown into it and held it taut. In the figure, (2) is the water supply and drainage port, (
3) represents a porous sheet. The effective evaporation area of water in the channel unit of FIG. 2 was approximately O9 Ueda2.

Porous hydrophobic polymer element 1 For example, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polyester,
and fluororesin, etc. are used. In addition, the average diameter of the countless fine pores present in this material allows water vapor (gaseous water molecules>ri) to pass through freely, but prevents water (liquid water molecules) from passing through the channel unit. In order to hold it in the hollow part, the resistance to water vapor increases below 0.1/l1m, and water can easily pass through when it is above 10μm, so the range is from 0.1μm to 10μm. desirable.

In addition, when water is supplied under pressure, for example, when water is supplied with a po/g, the pressure may be slightly increased and the water may seep out from the material, but this does not pose a practical problem. In this implementation v11Vc, a porous polyethylene sheet metal with an average pore diameter of 1 μm and a thickness of 1/2 μm was used.

A humidifier as shown in FIG. 3 was prepared by arranging 50 basin units of FIG. 2 using 4 mm thick plastic plates as spacers. In the figure, (4) represents a flow path unit, (5) a spacer, (2) a water supply port, and (6) a water supply pipe.

When dry air is blown around the outer periphery of the channel unit from the direction (a) in FIG. 3, humidified air (b) is blown out at the same time.

The results of calculating the humidifying capacity fA11 using Humidifier 4, which has an evaporation area of water of about 5 m2, are shown in the characteristic diagram of FIG. 4 by a solid line.

The horizontal axis #Il represents the wind speed, and the vertical axis represents the evaporation rate of water per 1 m2 of evaporation area. The evaporation rate of water depends on the air conditions, and the air conditions in (a) in the figure below are those in which dry air with a by-product of 40'C and a relative humidity of 20 degrees is used.7? :Represents the case, (b) The temperature in the room is 25℃,
The case is shown using dry air with a relative humidity of 50%.

As a comparative example, the same porous sheet was attached to the frame in Figure 1 with the same dimensions as the humidifying element-Z, and the results of measuring the humidifying ability of Humidifying 4 without Kuuchi Sogokai? Also shown in Figure 4. In order to suppress the swelling of the 7JO wet-condensed porous sheet, it was hung from both sides with a metal net. According to the results shown by the broken line in FIG.
It was found that the increase was approximately 0%.

In addition, even in the case where the material is a porous hydrophobic polymer, the resistance to water vapor is very small when the average pore diameter of the micropores is in the range of 0.1 to 10 μm. As a result, the flow path unit formed by this sheet allows water to flow into the hollow part, and only the water vapor is released to the outside to moisten the dry air without letting the water escape. The 1ffll humidifier's complete configuration, which is not available in the United States, can reduce the amount of moisture and increase the evaporation area of water. Furthermore, if a humidifier is configured as shown in FIGS. 2 and 3, the evaporation product of water can be greatly increased, and the humidifying capacity can also be greatly improved.

The humidifier according to the present invention is housed in the flow path unit '1 casing shown in Figure 2 or Figure 3, and is used by being connected to the dry air outlet of an air conditioner or heater, but when used independently as a humidifier 4. It can also be used in combination with a blower such as a fan or blower.

Effect of 6 shots (7)] As explained above, according to the present invention, the flow channel formed of a porous hydrophobic polymer material that prevents the passage of water and allows all the water vapor to pass through is partially internalized. water is supplied to the flow path unit from one end of the flow path unit, and the air blown around the outer periphery of the flow path unit has a highly porous hydrophobic structure. By humidifying the water that has passed through the molecular material, the lateral expansion f'1 due to the water's own weight is completely prevented, increasing the evaporation area of the water and making the air flow more turbulent. Increased ability 1
Jll] It has the effect of extending the life of the humidifier.
