Abstract

The present invention relates to an apparatus for cleaning a filter of a ceiling-type air conditioner, which sprays cleaning water while rotating a nozzle part to clean filters arranged in a rectangular shape of the ceiling-type air conditioner. A cleaning part (10) provided with the nozzle part (30) is mounted on a gear wheel (13) and rotated, wherein the gear wheel (13) is rotatably disposed on a support part (12) formed on a base plate (11) and is rotated by a driving means. The cleaning part (10) includes a reciprocating means (20) for reciprocating the nozzle part. The reciprocating means (20) is formed in a rectangular shape corresponding to the ceiling-type filters arranged in a rectangular shape, and reciprocates the cleaning part (10) back and forth in a radially outward direction of the gear wheel (13) in cooperation with the outer contour of a base plate (11) having rounded corners corresponding to the corner portions where the filter are disposed. Accordingly, the nozzle part for spraying the cleaning water for cleaning the filters is mounted on the gear wheel and reciprocates back and forth with respect to the filters while being reciprocally rotated, so that the nozzle part advances more at a filter portion at the corners than at a filter portion at the front, thereby increasing a spraying pressure of the cleaning water sprayed by the nozzle part. As such, it is possible to achieve a clean filter cleaning effect for the entire filter including the corner portions. The apparatus for cleaning a filter can be lifted and lowered by means of a collapsible elevating unit in correspondence with the height of a ceiling and can be housed in a housing for storage and transportation, thereby making it possible to perform movement, storage, and operation more efficiently and simply.

Description

Ceiling Air Conditioner Filter Cleaning

The present invention relates to a ceiling type air conditioner filter cleaning device, and in particular, to the air conditioner filters arranged in a square shape, while rotating the cleaning means at a predetermined angle to move the cleaning means back and forth to a constant pressure to the corner between each filter The present invention relates to an improved ceiling-type air conditioner filter cleaning device to spray the washing water on the filter to clean the air conditioner filter simply and cleanly.

The present invention also relates to an improved ceiling-type air conditioner filter cleaning device capable of reciprocating the nozzle portion in the vertical direction to spray the washing water up and down.

In recent years, system air conditioners are mostly installed in buildings such as large buildings, public institutions, and public facilities. In particular, ceiling-type air conditioners embedded in ceilings are rapidly increasing in use due to the limitation of flat space.

In the ceiling air conditioner, a refrigerant such as a freon gas is compressed to a high temperature and high pressure by a compressor and sent to a condenser, and the high temperature and high pressure refrigerant of the condenser is cooled and converted to a low temperature and high pressure, and then passed through a capillary and reduced to a low temperature and low pressure, and then passed through an evaporator. While absorbing the surrounding heat, the outside air is sucked in to remove the fine dust and the like with a filter and cooled to supply the room to perform the indoor cooling.

Such a ceiling air conditioner causes contamination of a filter that filters fine dust in the intake air in the process of circulating cooling the indoor air.As a result of the contamination of the air conditioner, the air conditioner efficiency is reduced and the pollutants in the air cannot be filtered out and diffused. There have been problems such as causing various respiratory diseases.

In order to solve this problem, various types of cleaning devices are known to clean the filter of the ceiling air conditioner. After removing the lower cover of the ceiling air conditioner in one of these forms, the lifting means are raised and lowered by the lifting means and positioned inside the air conditioner filter, and the filter is cleaned by the washing water sprayed from the washing water nozzle of the washing means.

At this time, the ceiling air conditioner filter is to wash the filter as a whole by spraying the washing water in all directions by rotating the wash water nozzle by the drive motor in the filter center position with respect to the filters arranged along the circumference of the air conditioner. And the washing water washing the filter was collected by the lower drip tray.

However, the conventional ceiling-type air conditioner filter cleaning device has the following problems.

First, since the washing water nozzle of the washing means rotates in a state located in the center of the air conditioner filter and sprays the washing water, the distance between the washing water spraying position and the filter is far from the cleaning efficiency.

In particular, since the air conditioner filter is mainly formed in a square shape rather than a circular shape, there is a problem in that the washing efficiency is further lowered since the washing by the washing water does not proceed evenly than other positions.

Second, since the cleaning state of the air conditioner filter, that is, before and after washing, cannot be checked, it must be checked separately after washing, so the workability is inconvenient to check. There was a problem falling.

Third, since the washing water nozzle is washed while rotating indefinitely, there is a problem that the water hose or various power lines are twisted during the rotation of the washing water nozzle, causing frequent failures.

Fourth, there is a problem that the assembly productivity, manufacturing productivity, etc. are significantly reduced by the assembly structure for assembling the various parts and the drip tray of the washing means complex.

As a countermeasure, the present inventors have a chain that moves while maintaining a predetermined distance from the filter inner surface along the outer circumference of the body inserted into the filter of the ceiling air conditioner, and the washing water is installed outside the chain and sprays the washing water toward the filter inner surface. Washing means including a nozzle, an endoscope camera installed adjacent to the washing water nozzle outside the chain to check the cleaning state of the filter, and a drip tray installed at the lower part of the body to collect washing water falling after washing; Elevating means for raising and lowering the washing means into the filter of the ceiling air conditioner; There has been proposed a ceiling type air conditioner filter cleaning device comprising a support means for supporting it.

However, since the filters are arranged at right angles, for example, in a quadrangular shape, the spacing between the nozzle and the filter increases at the corner when the washing water is sprayed while the washing water nozzle of the washing means is rotated in the center of the air conditioner filter. In the case of the negative filter parts, since the washing water injection pressure is relatively lower than that of the front filter part, the washing is not performed cleanly, and if the washing water pressure is increased to prevent this, the front filter part may be damaged. There was a problem that the cleaning efficiency is lowered at the furnace corner.

In addition, it was necessary to improve the structure to simplify the movement and operation of the filter cleaning device.

An object of the present invention is to solve the problems caused by the above-described ceiling air conditioner filter cleaning apparatus of the prior art, while rotating the nozzle unit for the filters arranged in a square shape in the ceiling air conditioner and at the same time the filter of the corner compared to the filter unit of the front By moving the nozzle part forward and backward to move further with respect to the part, the washing water spray pressure by the nozzle part is increased at the corner part, so that the ceiling air conditioner filters can be cleaned more easily and cleanly, and the carrying and moving can be easily accommodated in the housing.
