Description

[0001] The present invention relates to an air vent filter cartridge and an air purifier including the same,

The present invention relates to an air vent filter cartridge, and more particularly, to an air vent air vent filter cartridge that improves the filtration performance and life of the filter and prevents contamination from external contaminants, and a water purifier including the same.

Inside the water purifier, a water tank for storing purified water is installed. In such a water tank, outside air is naturally introduced into the tank due to a pressure difference caused by water in the tank.

Therefore, it is required to install a filter for filtering the contaminated air so as to prevent it from flowing into the water tank.

1, the conventional water purifier has a structure in which a part of the tank cover 20 located above the water storage tank 10 is opened and the filter 30 is opened to filter the air flowing into the water storage tank 10 And installed air was filtered.

In recent years, a HEPA filter (High Efficiency Air Filter) has been widely used as a filter 30 to be installed. The HEPA filter is a high-performance trapping filter and is widely used because the dust collection rate in the air is considerably high.

However, since the HEPA filter has a relatively short life span and is very susceptible to moisture, it has very small pores for collecting high-performance dust. Therefore, moisture can be introduced into the filter due to pollution sources other than dust or air, There is a problem in that the filter 30 is attached to the opening of the tank cover 20 in the case of the conventional water purifier shown in FIG.

Korean Patent Laid-Open Publication No. 2009-0082576 discloses a technique of filtering air using a HEPA filter, and the inconvenience of replacement is improved to some extent, but there is still a problem of shortening the service life due to the above-mentioned moisture and contamination.

The air vent filter cartridge according to the present invention and the components constituting the water purifier can be used integrally or individually. In addition, some components may be omitted depending on the usage form.

Preferred embodiments of a water purifier according to the present invention will be described with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, the definitions of these terms should be described based on the contents throughout this specification.

Hereinafter, an air vent filter cartridge and a water purifier according to an embodiment of the present invention will be described in detail with reference to FIG. 2 to FIG.

The water purifier according to one embodiment of the present invention includes a reservoir tank 100, a tank cover 200, and an air vent filter cartridge 300 as shown in FIG.

The water storage tank 100 is located in the water purifier and is a space in which purified water is stored. The water outlet pipe 110 for discharging purified water to the outside of the water purifier is disposed through the water storage tank 100.

The tank cover 200 is positioned above the water storage tank 100 and seals the water storage tank 200. The water supply pipe 210 for allowing the purified water to flow into the water storage tank 100 is located at one side of the tank cover 200 .

3, the air vent filter cartridge 300 is connected to an upper portion of the tank cover 200 and includes an air vent filter cover 310, a vent pipe 320, a filter unit 330, .

The air vent filter cover 310 is hollow in which one side is open, and the shape and the direction in which the air vent filter cover 310 is opened are not limited, but a hollow cylindrical shape with an open bottom is taken as an example.

The air vent filter cover 310 protects the filter unit 330, which will be described later, from moisture caused by dirt or condensation from the inside of the water purifier.

One end of the air vent pipe 320 is inserted into the open side of the air vent filter cover 310 and the other end is positioned to pass through the tank cover 200, So that air can be introduced into the interior of the apparatus 100.

3, the vent pipe 320 has a diameter smaller than that of the air vent filter cover 310. Accordingly, one end of the vent pipe 320 located below the air vent filter cover 310, A ventilation passage 340 is formed between the inner circumferential surface of the cover 310 and the outside air.

The filter unit 330 is interposed between the air vent filter cover 310 and one end of the vent pipe 320 to perform filtration of air introduced from outside. The material of the filter unit 330 is not limited, A polyurethane foam or an electroless electrostatic filter which is antimicrobially treated is preferable.

A non-powered electrostatic filter is a filter with electrostatic dust collecting function that collects and removes various contaminants by using the electrostatic principle. It generates static electricity on the surface of the filter by using air flow without power source and collects fine dust.

In addition, the filter portion 330 may comprise a plurality of layers, in which case at least one of the plurality of filter layers is preferably an electrostatic filter. For example, a three-layer structure of a second filter 332 located between a pair of first filters 331 and a first filter 331 as shown in FIG. 3, wherein the first filter is a polyurethane foam , And the second filter is preferably an electrostatic filter.

Hereinafter, the air filtering process in the air vent filter cartridge and the water purifier according to the embodiment of the present invention will be described with reference to FIG. 2 and FIG. 3 again.

First, when purified water in the water storage tank 100 is discharged to the water outlet 110, the inside of the water storage tank 100 is sealed by the tank cover 200, so that a difference in air pressure is generated, And is introduced into the water storage tank 100 through the cartridge 300.

At this time, due to the structure of the air vent filter cartridge 300, the air ascends through the ventilation flow path 340 and flows into the filter part 330 side for filtration. The filtered air descends and flows through the ventilation pipe 310 And then flows into the tank 100.

Since the air is introduced into the filter unit 300 from the lower portion of the air vent filter cartridge 300, relatively heavy or particulate dust in the air does not flow into the filter unit 330 before entering the filter unit 330, 330 can be used for a long time.

In addition, the air vent filter cover 310 may be provided with display means (not shown) for notifying when the filter is to be replaced. The display means is not limited, but an indicator or the like whose color changes after a certain period of time may be attached.

Hereinafter, another embodiment of the air vent filter cartridge and the water purifier according to the present invention will be described with reference to FIGS.

In the following description of other embodiments, for the sake of understanding and explanatory convenience of the present invention, differences from the above embodiment will be mainly described, and description of the same constitution will be omitted.

The water purifier according to another embodiment of the present invention includes a reservoir tank 100 and an air vent filter cartridge 400 as shown in FIG.

The air vent filter cartridge 400 is installed on the opened upper portion of the water storage tank 100 to seal the inside of the water storage tank 100 and includes an air vent filter cover 410, a vent hole 420, a filter portion 430, And an air flow path 440.

That is, in this embodiment, the tank cover 200 in the above embodiment is not installed, and the air vent filter cartridge 400 performs the sealing function of the tank cover 200, And is positioned through one side of the upper portion of the air vent filter cartridge 400 so that purified water flows into the water storage tank 100.

The air vent filter cover 410 may have a hollow shape and may be formed integrally with the upper cover 411 and the lower cover 420 as shown in FIG.

The air vent hole 420 is formed at the bottom of the air vent filter cover 410 so that the filtered air flows into the water tank 100.

The filter unit 430 is located inside the air vent filter cover 410 and may be formed of a plurality of filter layers as in the embodiment.

The ventilation flow path 440 is opened at a side of the air vent filter cover 440, through which external air flows into the air vent filter cover 410.

Referring to FIG. 4 again, air filtration in this embodiment will be described. When water purified by the water outlet pipe 110 is discharged, a pressure difference occurs in the water storage tank 100 and external air flows into the air flow path 440 The air is filtered through the filter unit 430 inside the air vent filter cover 410 and the filtered air flows into the water storage tank 100 through the air vent 420.

Since the area of the air vent filter cover 410 can be widened by enlarging the area of the air vent filter cover 410, the filtration in the filter unit 430 can be performed more effectively The life of the filter unit 430 is extended and the water storage tank 100 can be sealed in place of the tank cover 200 as described above and the effect of the embodiment can be obtained with a simpler structure.

According to the air vent filter cartridge and the purifier according to the present invention, since the structure of the electrostatic filter and the air vent filter cover increases the filtration efficiency of fine dust in the air and prolongs the life of the filter, It is possible to prevent contamination of the filter from a pollution source other than the air.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims. It will be understood that the present invention can be changed.
