Abstract

PURPOSE:To permit humidification by a method wherein a water absorbing device is arranged between a dust removing filter and a heat exchanger and water supplied to the water absorbing device is evaporated. CONSTITUTION:The air filter 8 is formed by a net made of a synthetic resin and the water absorbing device 10 is constituted by the net of metal, whose surface is applied with filling, medical treatment or the like. In case of humidifying in winter under effecting room heating, water is sent into a water reservoir 9 arranged above the heat exchanger. When water is reserved in the groove 9a of the water reservoir 9, the water is sucked up into the water absorbing device 10 abutting against the groove 9a and is supplied to a reticulated part in front of the device 10, then, the water is evaporated into suction air passing through the reticulated part thereby effecting the humidification.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a humidifying device for an air conditioner, and particularly to a humidifying device for an air conditioner suitable for humidification in heat pump type heating.

[Prior art]

A conventional air conditioner will be explained with reference to FIG. FIG. 1 is a longitudinal cross-sectional view of an indoor unit of a separate air conditioner, in which 1 is a casing that broadly forms a cabinet.

2 is a blower, 3 is a heat exchanger, and 4 is a dew pan for receiving dew condensed on the heat exchanger 3 during cooling operation on the lower side and guiding it to the outside of the machine. Reference numeral 5 denotes a decorative cover whose front surface covers the blower 2, heat exchanger 3, dew pan 4, and other parts installed in the casing 1. In addition, this makeup cover 5 has 5
The air inlet a and the air outlet 5b are integrally formed. Reference numeral 6 denotes an air filter, which is installed between the air suction port 5a and the heat exchanger 3, and is used to remove dust and the like from the intake air and prevent dust and the like from adhering to the heat exchanger 3. The lower side of the air filter 6 is integrally formed with a handle 6a that protrudes from the decorative cover, and can be pulled out from the decorative cover 5 by pinching the handle 6a with your fingers.

Also, the arrows in the figure indicate the flow of wind.

As explained above, air conditioners do not have a humidifying function, so when heating with an air conditioner that is also used for heating and cooling, the temperature rises without humidification, and the relative humidity decreases, making you feel dry and uncomfortable. . In addition, in the case of an air conditioner dedicated to cooling, use other heating equipment, such as a stove or heater, to heat the air conditioner, and then use the blower 2.
There is also a method of use in which the air inside the room is circulated by only operating the room, but this also has the same drawbacks as above, such as the relative humidity being dry at the bottom and making it feel uncomfortable.

[Purpose of the invention]

An object of the present invention is to provide a humidifying device for an air conditioner that supplies water to the air conditioner and enables humidification.

[Summary of the invention]

It has a heat exchanger and a blower, and a moisture absorbing net is placed in parallel with the heat exchanger, and water is supplied to the absorbent net to evaporate the moisture contained in the moisture absorbing net to humidify and adjust the temperature. This is a device that performs full-scale humidity control outside of the room.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. FIG. 2 is a longitudinal sectional view of the separate indoor unit of the present invention, and FIG. 3 shows an installation example of the separate indoor unit of the present invention. Note that the same symbols and numbers as in the conventional example have the same functions, so the explanation will be omitted.

A decorative cover 7 integrally forms an air inlet 7a and an air outlet 7b. Reference numeral 8 denotes an air filter, which is attached to the air suction lower a of the decorative cover 7.

The air filter 8 is made of a synthetic resin net and charged with an electric charge to further improve dust removal efficiency.

8a is a handle; pinch this handle 8a with your fingers and remove the makeup cover 7.
It is now possible to draw out more. The arrows in the figure indicate the flow of wind.

Reference numeral 9 denotes a water reservoir for temporarily storing water, which is disposed above the heat exchanger 3, and a deeper groove 9a is formed on the front side of the heat exchanger 3. 1° is a water absorption device, and the surface of the metal mesh is treated with flocking or chemical treatment to absorb water. A similar effect can also be obtained by attaching a nonwoven fabric with good water absorption to the surface of the metal mesh. The shape is such that one end is in contact with the groove 9a of the water reservoir 9, and the other end 10b is in contact with the surface of the heat exchanger 3. A gap is provided between this water absorption device IO and the air filter.

11 is a water tank equipped with an air pump lla at the top,
When the air pump 11a operates, the pressure inside the water tank 11 increases, and the water in the water tank 11 is sent into the pipe llb that communicates the water tank 11 and the water reservoir 9. The interior of the hoar pump 11a is designed to prevent water from passing through.

With the above configuration, when heating and humidifying in winter, when the air conditioner is set to heating operation, the heat exchanger 3
acts as a radiator and becomes high temperature.

In this state, when the air pump 11a is operated, water in the water tank 11 passes through the pipe llb and is sent into the water reservoir 9. When water collects in the groove 9a of the water reservoir 9, the water is sucked up by the water absorption device 10 that is in contact with the groove 9a, and the water is replenished into the net-like part on the front side, where it evaporates into the suction air passing through this part, humidifying it. It is something to do.

Since the water reservoir 9 is arranged at the upper part of the heat exchanger 3, the temperature of the water increases while the water is stored in the water reservoir 9, making it easy to evaporate. Moreover, the water absorption device 10 is made of metal, and this tip 10b
Another good point is that since the part is in contact with the heat exchanger 3, the temperature rises and the water evaporates easily.

A humidity sensor is installed on the suction air side, and the air pump 11.8 is controlled in accordance with instructions from the humidity sensor. In addition, there are other methods such as interlocking with the operation of an air conditioner or operating the air pump lla at regular intervals, but the method of interlocking with a humidity sensor is the best because it allows direct control of the humidity. If the amount of water supplied is greater than the amount of water evaporated from the water absorption device, it is guided from the tip of the water absorption device 10b to the heat exchanger 3 and evaporated there. If the water is still not completely evaporated, it is led to the dew pan 4 and drained. Since a gap is provided between the dust removing filter 8 and the dust removing filter 8, water does not flow out along the dust removing filter 8.

Since the dust removal filter 8 is charged, it collects even minute dust, so it is also advantageous that the water absorption device 10 is prevented from being blown away by dust.

If the humidity sensor detects low humidity other than during heating operation, by operating the air pump lla and the blower 2, the water absorption device 10 can be replenished with water, and this water is absorbed and evaporated into the air, thereby being used as a humidifying device. It's good to be able to do it.

〔Effect of the invention〕

According to the present invention, by arranging the water absorption device between the dust removal filter and the heat exchanger of the air conditioner, the humidification function can be easily performed, so that it is effective as humidification during air conditioning and heating. Furthermore, when the water absorption device contains water, when the intake air passes through the water-containing net, the water can collect very fine particles that could not be collected by the dust removal filter. effective.
