Cleaning device for filter element

Abstract

The present invention is to provide a cleaning device for a filter element, comprising: a blower means which generates an air flow that passes through the inside of a filter element; a screen which moves in a vertical direction while being in close contact with the side surface of the filter element; and a through-hole formed in one side of the screen in a direction that coincides with an air proceeding direction in the filter element. The present invention does not cause a large structural change in the filter element and thus exhibits the effect of efficiently carrying out a cleaning operation while minimizing costs because the inside of the filter element can be cleaned on the basis of the fact that air passing through a nozzle with a smaller diameter has a greater pressure and faster speed than air passing through a nozzle with a larger diameter. That is, the invention is very effective because the through-hole is formed in the screen while occupying only a part in the area of the screen, and thus, the remaining part of the screen blocks the inside of the filter element and air can only flow through the through-hole when the air flow is formed by the operation of a blower. Accordingly, the air flow is naturally concentrated in the through-hole, and then, the air can pass through the inside the filter element with high pressure and high speed. Thus, dust and foreign substances accumulated in the filter element can be discharged, thereby carrying out the cleaning of the filter element.

Description

Cleaning device for filter elements

[0001] The present invention relates to a cleaning device for a filter element, and more specifically, to a filter element capable of effectively removing dust loaded inside a filter element mainly used in an air conditioning device.

[0002] In general, recently constructed buildings use air conditioning units (air conditioning systems) that forcibly suck in and exhaust indoor and outdoor air through ventilation fans and use filter elements to purify the air and save energy. The above-mentioned building air conditioning units are usually installed on the ceiling to efficiently utilize space and suck in and exhaust indoor and outdoor air through ducts.

[0003] In addition, these conventional air conditioners enhance their dust collection capabilities by allowing air to be sucked in and discharged through a filter element built into the middle of the case.

[0004] These filter elements not only collect dust on their surfaces, but also accumulate dust inside them. This slows airflow, hindering the air conditioning system's intended purpose of improving air quality.

[0005] In addition, if dust accumulates inside the filter, air flow becomes poor, which creates an environment where mold and other organisms can thrive, increasing the risk of contamination and ultimately requiring frequent replacement, which increases maintenance costs.

[0006] In addition, if the air flow is poor, it has the disadvantage of being difficult to quickly discharge indoor polluted air, noise increases due to air resistance, and energy costs increase due to increased power consumption.

[0007] However, the problem is that the dust accumulated inside the conventional filter element is not easy to clean.

[0010] The purpose of the present invention is to enable cleaning of the inside of a filter element while minimizing costs by not making as large a structural change as possible to the inside of the filter element, which was previously impossible, while in the case of a conventional filter element, and to clean the inside of the filter element by making the speed of the air passing through the inside of the filter element very fast without separately increasing the blowing pressure of the existing blower, taking into account that the pressure of the air passing through a nozzle of a small diameter is higher and the speed is faster than that of the air passing through a nozzle of a large diameter.

[0011] A cleaning device for a filter element according to an embodiment of the present invention for achieving the above-described purpose is characterized by a blowing means for forming wind passing through the inside of the filter element, a screen that is raised and lowered in close contact with a side of the filter element, and a perforation formed in a direction matching the direction of air movement of the filter element on one side of the screen.

[0012] Another embodiment of the present invention is characterized in that the blower means is configured as a blower formed on one side or the other side of the filter element.

[0013] In another embodiment of the present invention, the raising and lowering of the screen is performed by a screen raising and lowering means, and the screen raising and lowering means is characterized by being composed of a roll for winding the screen and a motor for rotating the roll.

[0014] As for the effects of the present invention as described above, the present invention takes into account the fact that the pressure of air passing through a nozzle of a small diameter is higher and the speed is faster than that of air passing through a nozzle of a large diameter, and thereby enables cleaning of the inside of a filter element, thereby minimizing costs without making a large structural change to the filter element and effectively performing cleaning.

[0015] That is, by forming holes in the screen but manufacturing it so that the holes occupy only a portion of the screen area, when the air flow is formed by the operation of the blower, all other parts of the screen block the inside of the filter element and only the holes allow the air flow, so that the air flow is naturally concentrated only in the holes, and as the strong pressure and fast air pass through a portion of the inside of the filter element, dust and foreign substances loaded inside the filter element are discharged, making it possible to clean the inside of the filter element, which is a very useful invention.

[0022] Hereinafter, preferred embodiments of a cleaning device for a filter element according to the present invention will be described in detail with reference to the attached drawings.

[0023] FIG. 1 is a reference diagram showing a cleaning device for a filter element according to an embodiment of the present invention, FIG. 2 is a perspective view showing a filter element and an elevation device in the present invention, and FIG. 3 is a reference diagram showing the elevation state of the elevation device in the present invention.

(i) is the stage where the screen is rolled by the lifting device, i.e., the normal operation mode; (ii) is the stage where the screen is raised by the lifting device and the aperture starts to rise from below, i.e., the filter element cleaning mode, where the inside of the lowest part of the filter element is being cleaned; and (iii) is the stage where the screen is raised a little further and cleaning is completed up to the inside of the highest part of the filter element.

[0024] First, it should be noted that, among the drawings, identical components or parts are indicated by identical reference numerals, where possible. Furthermore, in describing the present invention, detailed descriptions of related known functions or configurations are omitted to avoid obscuring the gist of the present invention.

[0025] The cleaning device (100) for a filter element of the present invention is composed of a blowing means for forming wind passing through the inside of the filter element (20), a screen (12) that is raised and lowered in close contact with the side of the filter element (20), and a hole (13) formed on one side of the screen (12) in line with the direction of wind movement of the filter element (20).

[0026] The above blower means is composed of a blower (30) formed on one or the other side of the filter element (20). At this time, the blower means is configured to be built into the case (1) so that air can flow inside the filter element.

[0027] In the present invention, the screen device (10) is composed of a screen (12) and a screen raising / lowering means. The screen (12) refers to a windproof cloth, and the screen raising / lowering means is composed of a roll (not shown) for winding the screen (12) and a motor (11) coupled to the shaft (not shown) of the roll. At this time, the lower end of the screen (12) may be provided with a pleated portion (12a) to allow for easy folding, and may further be provided with a weight (12b). In addition, a known winding means, i.e., a roll and a motor, may be further provided for forcibly winding the lower end of the screen (12).

[0028] The reason why the lower part of the above screen (12) must be folded or rolled up is that when the hole (13) of the screen (12) rises upward, the flow of air must be blocked from other parts of the filter element (20) by the lower screen (12). In other words, the lower part of the screen (12) must be folded so that the screen (12) can easily rise in a state in which it is in close contact with one side of the filter element (20).

[0029] The height and width of the hole (13) of the above screen (12) should be such that a strong air flow can be formed, and it is preferable that it be formed horizontally so that the inside can be cleaned sequentially from the bottom to the top of the filter element.

[0030] Referring to Fig. 4, (i)(ii) is the normal operation mode, so the screen (12) is rolled up and has nothing to do with cleaning, and (ii) is the cleaning mode, so when the blower (30) is operated in the cleaning mode while the hole (13) of the screen (12) is located at the bottom of the filter element (20), the screen (12) is pressed against one side of the filter element (20) by the air pressure, and in that state, the screen (12) is also wound as the roll is wound by the operation of the motor (11), and thus the hole (13) rises, completing cleaning from the inside of the bottommost part of the filter element (20) to the inside of the topmost part.

[0031] In this way, the present invention proposes the best structure that can effectively clean while minimizing costs by not making as large a structural change as possible to the interior of the filter element (20) that was previously impossible, and can be installed relatively cheaply and easily in existing air conditioning devices.

[0032] In the present invention, the above-mentioned aperture (13) occupies only a portion of the area of ​​the screen (12), and when the blower operates to form an air flow, the other portion of the screen (12) blocks the inside of the filter element (20), and allows the air to flow only through the aperture (13). In this way, the air flow is concentrated only in the aperture (13) of a narrow area, so that the fast air is discharged only through the inside connected to the aperture (13), thereby removing dust and foreign substances with strong pressure.

[0033]

[0034] As described above, although the present invention has been described by limited embodiments, the present invention is not limited thereto, and various modifications and variations are possible by a person having ordinary skill in the art to which the present invention pertains within the scope of the technical idea of ​​the present invention and the equivalent scope of the patent claims to be described below.
