Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a humidifying device mainly attached to a ceiling, which purifies and humidifies the air atmosphere of an office, school, store, etc.

[Prior art] According to the Building Standards Act, the Act on Maintaining a Hygienic Environment in Buildings, the Industrial Safety and Health Act, etc., the indoor humidity in buildings must be within the range of 40% to 70%, and the indoor dust concentration should be kept within the range of 40% to 70%. It is instructed or required to maintain the amount below 0°15 mg/m'. To maintain such a humid atmosphere and air cleanliness, active humidification and air purification are necessary.For humidification, especially in the winter when heating is performed, it is necessary to use forced humidification to keep the indoor relative humidity within an appropriate range. Can't keep it.

In light of this, conventionally, air conditioners (also known as central air handling units) and large luggage near conditioners have built-in ultrasonic or water spray type humidifiers and air filters. It has sufficient humidification and air purification functions. However, in the case of relatively small individual air conditioners, it is difficult to incorporate a humidifier or air filter that provides sufficient humidification inside the unit, as this increases the size and reduces air volume. Air conditioners that are mounted on the ceiling have strong dimensional restrictions.
Currently, the solution is to incorporate a humidifier with a small capacity or an air filter with low air purification function in each air conditioner, combine it with an external humidifier, or install a separate humidifier. are doing.

A type of humidifying device embedded in the ceiling, for example, as disclosed in Japanese Patent Laid-Open No. 62-98138, uses a blower to pass the air to be treated through an endlessly rotating humidifying medium, and then the treated air is humidified by the humidifying medium. Some are made to emit air into the room.

[Problem to be solved by the invention] Conventional humidifiers associated with relatively small individual air conditioners cannot cope with the increase in the amount of humidification required due to air conditions, ventilation, etc. However, depending on the humidification method, there are many problems such as over-humidification.Also, with ultrasonic humidifiers that generate fog using ultrasonic waves, the amount of fog generated by ultrasonic waves is constant, so Changes in state quantities such as air flow and air flow rate (e.g. when the air filter becomes clogged)
However, the amount of humidification remains the same, and carryover may occur due to excessive humidification.

Furthermore, humidifiers that pass the air to be treated through rotating humidifying media include a drive device, etc., which not only makes the device complex and bulky, but also causes a drop in performance due to adhesion of dust, etc. in the air to the humidifying media. It lacks durability and stability in terms of function, and it is difficult to obtain a satisfactory air purification function.In addition, the humidifying media that generates high humidity and the water tray that supplies water to it are prone to breeding bacteria and mold in the pan. This includes issues that need to be resolved, such as the fact that the treated air tends to be permanently contaminated with gametes, germs, mold, etc.

This invention was made in order to solve such conventional problems, and has a simple structure, high applicability, good durability and functional stability, and hygienic humidification with high purity of treated air. The purpose is to obtain a device.

[Means for Solving the Problems] A humidifying device according to the present invention does not include a drive system and humidifies and blows out air to be treated introduced from an air conditioner or the like, and humidifies air introduced from an inlet. The air filter section that passes through the treated air and purifies the air to be treated before humidifying it is provided with at least a sterilizing function or a mold-proofing function.

Further, another humidifying device according to the present invention includes an air filter section that passes through the air to be treated that is introduced from the inlet and purifies the air to be treated before humidifying the air. The air filter is composed of a filter for air purification and a gas adsorption filter for removing gas components, and the air filter part is provided with at least one of a sterilizing function and a mold-proofing function.

Furthermore, another humidifying device according to the present invention has two types of dust removal filters in the air filter section that purify the air to be treated introduced from the inlet before humidification, a coarse dust removal filter and a medium-high performance filter. The air filter section is provided with at least a sterilizing function or a mold-proofing function.

[Operation] In the humidifying device of the present invention, the air to be treated that is introduced from the air conditioner etc. through the inlet is purified through the air filter section, and is passed through the humidifier as the air to be treated from which dirt components such as dust have been removed. The purified air can be humidified and blown into the room from the outlet as purified humidified air, and the air filter section that purifies the air to be treated can become a source of germs, mold gametes, etc. This not only eliminates waste, but also improves the cleanliness and hygiene of the treated air.

In addition, in another humidifying device of the present invention, the air filter section can remove dust and gas components from the air to be treated before humidification to make it clean and odorless, and the air filter section can remove dust and gas components from the air to be treated before humidification. Not only will it not become a source of gametes, etc., but the cleanliness of the treated air can be further improved.

Furthermore, in another humidifying device of the present invention, the performance of removing particulate components such as dust especially in the air filter section is improved,
It becomes possible to capture gametes of bacteria or mold in the air filter section.

In particular, for the coarse dust filter 4a, the filter medium constituting the filter is impregnated with a bactericidal agent, an antibacterial agent, and an anti-mold agent. The filter medium is made of fibers made from a mixture of sterilizing and mold-fighting functions. As the bactericidal and fungicidal agent, for example, a quaternary ammonium salt-based bactericide, a halogenated nitrogen-sulfur compound (isothiazolone, etc.), or a bactericidal agent such as cyabentazole is used. It has a sterilizing effect on the germs and mold gametes contained in the passing air A, and also prevents the breeding of bacteria and the generation of mold in the trapped dust part. The air filter section 4 is provided with a sterilizing function and an anti-mold function, for example, by installing an ultraviolet sterilizing device, without relying on a sterilizing agent or an anti-mold agent, but it is also possible to use both in combination.

The medium-high performance filter 4b is a mechanical filter using a filter medium, but it may also be a combination of a filter medium and an electrostatic precipitator, such as an electrode plate type electrostatic precipitator or a filter medium dielectric type.The last stage gas adsorption filter 4c is , is constructed as shown in FIGS. 3 and 4 in order to adsorb and remove gas components (cigarette smoke components, petroleum vapor, etc.) contained in the air to be treated A. That is, a honeycomb core 4f filled with granular activated carbon 4e is housed in an outer frame 4d, a net 4g is stretched between the end face where the air to be treated A is introduced and the end face where it is discharged, and the zero granular activated carbon 4e is fixed to the outer frame 4d. may be replaced with a porous material such as porous ceramic powder, ceramic grains, or zeolite, or a material that adsorbs or decomposes gas by catalytic action.The structure of the gas adsorption filter 4C is that the gas adsorption material is directly formed into a foam. It may be formed into a foam, a gas-adsorbing substance is attached to a foam-like base material, or it is pressed by a foam-like base material.Furthermore, gas-adsorbing chemicals or gas components such as metal phthalocyanine derivatives may be used. A chemical with adsorption and resolution capabilities of

The humidifier 5, which is the core of the humidifying function, is either a water-absorbing humidifying plate type made of porous hydrophilic plastic as shown in FIG. 5, or a moisture-permeable membrane type as shown in FIG. applicable.

In the former method, a plurality of water-absorbing humidifying plates 9 made of porous hydrophilic plastic are arranged in a comb blade shape parallel to the flow of the air to be treated A, and water is supplied to each of the water-absorbing humidifying plates 9. There are configurations that combine water supply systems. That is, the lower end is provided with a stepped end surface 10 and a stepped bottom end surface 10, and the water receptacle 11 is made of a plurality of substantially concave water-absorbing humidifying plates 9 with the stepped end surface 10 as a stepped bottom. It is held vertically so that it fits. As for the water receptacle, the part with the shallow bottom of the container 11 is the water supply tray 12, to which the water supply pipe 13 is connected, and the higher end face of the stepped end face 10 of each water absorbent humidifying plate 9 is the water supply pipe 13.
It is designed to be immersed in water supplied from In addition, the water receptacle is the part with the deep bottom of the container 11, which is the drain pan 14.

A humidifier 5 has a layered air passage 17 in contact with the outer surface of the humidifier 5. In any of the above-mentioned humidifiers 5, even if water scale components (calcium carbonate, etc.) are concentrated due to water evaporation, this can be discharged by the drain vibe 15, and the function of the water-absorbing humidifying plate 9 and the bag [6] is that the scale deposited It is designed so that it is not damaged by the ingredients. Functionally, all of them are natural evaporation type, and appropriate humidification is achieved according to the state quantity regarding the humidity of the air A to be treated.

No carryover occurs due to excessive humidification or excessive humidification. In particular, the moisture-permeable membrane type humidifier 5 shown in Fig. 6 has a high degree of freedom in shape, and can easily realize a configuration that satisfies both the contact with the air to be treated A and the positional relationship with the water supply and drainage system. There are great advantages that can be achieved.

The indoor air to be treated A drawn in by the blower 32 is introduced into the humidifier, where it is cleaned, humidified as appropriate, and sent out into the room 28 6
In a room equipped with the air conditioner 34 shown in the figure, dehumidification occurs in the cooling state, and the room 28 tends to shift to a dry atmosphere, and static electricity is also likely to be generated. This is virtually impossible because the saturated absolute humidity is low and the amount of humidification cannot be obtained, and there is a risk of water droplets adhering to the electronic equipment 35 due to overhumidification. It is possible to purify and humidify indoor air without fear of overheating.

Moreover, since it is not structurally related to the air conditioner 34, it is possible to easily respond to changes in humidification capacity and air conditioning plans.

FIG. 8 shows an application example in which a ceiling-mounted air conditioner 36 and a humidifier are connected to form a comprehensive air conditioner that performs heating and cooling functions, air purification functions, and humidification functions. Figure 9 shows how it is combined with a floor-standing air conditioner 37, Figure 10 shows how it is combined with a ceiling cassette type air conditioner 38, and Figure 11 shows how it is combined with an outside air intake type air conditioner 39. In various application examples, a sanitary air conditioning system including a total humidification function and air purification function can be constructed by combining it with various types of air conditioners and the like. In particular, in the application mentioned above, the air (
