Description

[Detailed Description of the Invention] [Industrial Application Field] This invention purifies and humidifies the air atmosphere in offices, schools, stores, etc. by connecting it with other air conditioners with a blowing function, and is mainly applied to ceilings. The present invention relates to a humidifying device to be attached.

[Prior Art] According to the Building Standards Act, the Act on Maintaining a Sanitary Environment in Buildings, the Industrial Safety and Health Act, etc., it is instructed to maintain indoor humidity within a building within a range of 40% to 70%. Or required. To maintain such a humid atmosphere, active humidification is necessary, and especially in the winter when heating is performed, it is impossible to maintain the indoor relative humidity within an appropriate range unless forced humidification is performed. Based on this, in the past, air conditioners, also known as central air conditioning air handling units, and large package air = 7
The Ndayrayona is equipped with an ultrasonic or water spray humidifier to provide sufficient humidification. However, in the case of relatively small individual air conditioners, it is difficult to incorporate a humidifier that provides sufficient humidification function.
In particular, ceiling-mounted air conditioners, which have limited space, have strong dimensional constraints.Currently, it is necessary to incorporate a very small-capacity humidifier into each air conditioner, or to combine external humidifiers. This can be done by installing a separate humidifier. For example, as a type o') humidifying device embedded in the ceiling, as disclosed in Japanese Patent Application Laid-Open No. 62-98138, the air to be treated is passed through an endless rotating humidifier using a blower and humidified with humidifying media. Some models allow the treated air to be blown 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 with over-humidification. In addition, with ultrasonic humidifiers that generate fog using ultrasonic waves, the amount of fog generated by ultrasonic waves is constant, so even if state variables such as room temperature or air flow rate change, the amount of humidification will not change. Carryover may also occur due to excessive humidification. Furthermore, humidifiers that pass the air to be treated through a rotating humidifying medium include a drive device, etc., making the device complex and bulky, and the humidifying media can pick up dust and other particles in the air, reducing performance. Therefore, there are problems that need to be solved, such as a lack of durability and functional stability.

This invention was made in order to solve such conventional problems, and aims to provide a humidifying device with a simple configuration, high applicability, and good durability and functional stability. .

[Means for Solving the Problems] The humidifying device according to the present invention has a configuration that can be called a stationary type that does not include a drive system, and allows air to be treated introduced from an air conditioner or the like through an inlet to pass through the humidifying device to be treated. an air filter that purifies treated air; and a natural evaporation type humidifier that humidifies the treated air by natural evaporation of water, passing the treated air purified by the air filter downstream of the air filter; The humidifier is equipped with an air outlet through which treated air humidified by the humidifier is blown out.

Further, in another humidifying device according to the present invention, the humidifier of the humidifying device described above is provided with a plurality of water-absorbing humidifying plates made of porous hydrophilic plastic arranged in a comb blade shape in parallel to the flow of the air to be treated. At the same time, it is configured to supply water to each of the water-absorbing humidifying plates.

Furthermore, another humidifying device according to the present invention includes a bag formed of a moisture-permeable membrane and into which water is sent downstream of the air filter, and a bag that does not allow the air to be treated to pass through the outer surface of the bag. It is equipped with a humidifier consisting of an air passage.

Further, in another humidifying device according to the present invention, the air filter that purifies the air to be treated sent to the natural evaporation type humidifier is configured with two types of filters: one for 1171 removal and one for medium-high performance. .

In the humidifying device of the present invention, the air to be treated that is introduced from an air conditioner etc. through an inlet is purified through an air filter, and the air to be treated is treated by a natural evaporation type after removing dirt components such as dust. The purified air is passed through a humidifier, humidified, and then blown into the room from the outlet as purified humidified air.As it is a stationary type that does not include a driving device, it is durable and functionally stable. It is also highly adaptable to other air conditioners with ventilation functions, and can be widely used for appropriate humidification in places that require humidification.

Further, in another humidifying device of the present invention, the structure of the humidifier is particularly simple, and the humidity is good, and the air to be treated can be easily humidified by natural evaporation.

Furthermore, in other humidifying devices of the present invention, since the humidifier is constructed with a core of a bag body formed of a moisture permeable membrane into which water is fed, it has a high degree of freedom in shape, and the air to be treated is This makes it possible to easily configure the contact with the water supply and drainage system and the positional relationship with the water supply and drainage system.

Furthermore, in another humidifying device of the present invention, the air filter is composed of two types of filters, one for coarse dust removal and one for medium-high performance, so that the cleanliness of the humidified and blown out treated air can be determined. This makes it possible to create a more comfortable indoor atmosphere.

Inside the hook-shaped outer box 3 arranged linearly on the other opposing side, there is an air filter 4 that purifies the air to be treated A, and a natural evaporation type humidifier that humidifies the air to be treated A by natural evaporation of water. It has a configuration that incorporates a container 5. The outer box 3 is horizontally suspended and fixed in an attic space or the like by anchor bolts or the like that are attached to the structural members of the building in a hanging manner through hanging fittings 6 provided at the four corners of the upper surface.

The inside of the outer box 3 has a hollow structure that allows ventilation, and an air filter 4 is installed in the horizontal direction immediately after the introduction port 1 so that it can be taken in and out from an inspection lower that can be opened and closed in the front. A humidifier 5 is installed on the side of the air outlet 2 at the rear stage so as to be inspectable through an inspection port 8 provided at the front that can be opened and closed. The air filter 4 has a two-stage configuration: a front stage and a rear stage, and the front stage is a coarse dust filter 4a (weight method 25
~90%), and the latter stage is a medium-high performance filter 4
b (50 to 98% colorimetric method), and each is constructed by combining a plurality of 20 to 40 cm wide pieces to enable inspection and replacement through an inspection hole provided in the ceiling. The air filter 4 is a mechanical filter using a filter medium, but it may also be of a combination of a filter medium and an electrostatic precipitator, such as an electrode plate type electrostatic precipitator or a filter dielectric type. In addition, each inspection lower 8 may be provided on the bottom surface of the outer box 3, and even if the inlet 1 and outlet 2 are configured to allow duct connection, direct connection to the pond air conditioning equipment is possible. You can configure it.

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. 3 or a moisture-permeable membrane type as shown in Fig. 4. applicable.

In the former method, a plurality of water-absorbing humidifying plates 9 made of porous hydrophilic plastic are arranged in a willow blade shape parallel to the flow of the air to be treated A, and each water-absorbing humidifying plate 9 is provided with water. This configuration combines a water supply system that supplies water. That is, a water receptacle is fitted into a container 11, which has a plurality of almost concave water-absorbing humidifying plates 9 with a step end face 10 having a step end face 10 vertically, and a step bottom with a step end face 1o having two steps above and below. It is held vertically like this. As for the water receptacle, the part with the shallow bottom of the container 11 is a water supply tray 12 to which a 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 tray 12 which is supplied with water from the water supply pipe 13. It is designed to be immersed in water. In addition, the water receptacle has the deep bottom of the container 11 from 1 to 14.
A drain pipe 15 for drainage is connected thereto, and the lower end face of the stepped end face 10 of each water-absorbing humidifying plate 9 is accommodated. A parallel flow path is formed between each of the water-absorbing humidifying plates 9, through which the air to be treated A purified by the air filter 4 flows and reaches the outlet 2.

The latter includes a bag body 16 formed of a moisture-permeable membrane, such as a water-testable porous plastic film, that has micropores that allow water vapor to pass through but not water, and a bag body 16 that allows the air to be treated to pass through the outer surface of the bag body 16. It is composed of an air passage 17 configured as shown in FIG. That is, as shown in FIG. 4, a spacer 18 is placed inside the bag 16, and the spacer 18 holds the inner waterway and the shape of the bag 16. A water supply pipe] 3 is connected to one end of the bag body 16, and a drain pipe 15 is connected to the end thereof. Binding 1
6 itself is formed in a flat shape, one corfut layered separator is superimposed on this, and the whole is rolled up and placed in an outer frame 20 to have a layered air passage 17 in contact with the outer surface of the bag body 16. A humidifier 5 is configured. In any of the above-mentioned humidifiers 5, even if water scale components (such as calcium carbonate) are concentrated due to water evaporation, they can be discharged through the drain pipe 15, and the water-absorbing humidifying plate 9 or the bag body 16
The function of the product is not impaired by the precipitated scale components. Further, functionally, both are natural evaporation type, and appropriate humidification is achieved according to the state quantity regarding the humidity of the air to be treated A, so that overhumidification and carryover due to excessive humidification do not occur. In particular, the moisture-permeable membrane type humidifier 5 shown in FIG.

The air to be treated A drawn into the room by the blower 31 is cleaned and humidified appropriately by the front room device, and then sent to the room 2.
It can be sent to 7. Cooling conditions involve dehumidification,
The room 27 tends to become a dry atmosphere and static electricity is easily generated, but the humidification of the low-temperature air for cooling from the air conditioner 33 has a low saturated absolute humidity, making it difficult to maintain the amount of humidification, and overhumidifying the electronic equipment. However, according to the humidifying device of this embodiment, it is possible to purify and humidify indoor air without fear of excessive humidification or carryover caused by it. Furthermore, since it is not structurally related to the air conditioning equipment 33, it is possible to easily respond to changes in humidification capacity and air conditioning plans. Figure 6 shows the blower 31 of the above application example.
