Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filter cleaning device for cleaning filters attached to air conditioning equipment.

Conventional technology Generally, air conditioning equipment is equipped with a filter for removing dust from the air on the suction side.When removed dust accumulates, the pressure drop increases and the performance of the air conditioning equipment decreases. It is necessary to clean the filter regularly.

For this reason, conventional filters were cleaned by leaning the filter against a wall, holding the spray nozzle of a high-pressure washer in your hand, and spraying cleaning water at the dirt on the filter.

Problems to be Solved by the Invention In the conventional cleaning method described above, since it is carried out manually, it is hard work especially in winter and summer due to the cold and hot weather, and the cleaning results also vary depending on the worker. However, there were problems such as it took a long time to dry after washing.

The present invention is intended to solve these problems, and its primary purpose is to reduce the labor of workers and to stably obtain high cleaning effects. The second purpose is to shorten the drying time after washing.

Means for Solving the Problems In order to achieve the first object, the first means of the present invention includes a cleaning nozzle that spouts cleaning water, and an object to be cleaned that is placed at a predetermined distance from the cleaning nozzle. and a workpiece pedestal for tilting and supporting the filter on the opposite side of the cleaning nozzle μ, and one of the cleaning nozzle and the workpiece pedestal is moved in parallel by a drive device. That is.

A second means for achieving the second purpose is to use a cleaning nozzle that spouts cleaning water, an air nozzle that spouts pressure source air,
The cleaning nozzle and a workpiece pedestal are provided at a predetermined distance from the air nozzle to support the filter of the object to be cleaned, and one of the cleaning nozzle, the air nozzle μ, and the workpiece pedestal are parallel to each other by a drive device. This is a structure of a filter cleaning device that moves to

Effect: Due to the structure of the first means, the filter supported on the workpiece pedestal is sprayed with cleaning water from the cleaning nozzle;
The entire surface of the filter is cleaned by moving the filter or the workpiece holder by the drive device, and since the filter is tilted, the water after cleaning falls from the injection position to the opposite side.

With the structure of the second means, the filter supported on the workpiece pedestal is cleaned with cleaning water sprayed from the cleaning nozzle μ, and then the attached cleaning water is blown away by the air nozzle.

EXAMPLE A first example of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in the figure, the main body 1 has a flat plate-like finoletter 20 on the upper part.
It has a workpiece pedestal 2 that supports the workpiece pedestal 2 diagonally upward, and slide rails 3 are provided above and below the workpiece pedestal 2. A drive device 4 provided on the upper part of the slide tray/I/3 causes a cart 6 facing the workpiece holder 2 to slide on the slide tray 6/I/3.

Inside the truck 5, there is provided a water pipe 6A in which a large number of cleaning nozzles/L/6 are provided on a straight line intersecting the sliding direction of the truck 6 at right angles. The cleaning nozzle 6 is connected to a cleaning pump 7 provided at the bottom of the main body 1 by a flexible hose 7A in order to receive the supply of cleaning water.

In the above configuration, after the finoletter 20 is placed on the work tray 2 with the dirty side facing forward, the cart 5 is moved to the drive device 4.
Slide it along the slide tray/L/3 using the slide tray/L/3.

When the cleaning nozzle /l/6 attached to the trolley 6 comes close to the surface of the filter 2o to be cleaned, the cleaning pump 7 is started and the cleaning water is sprayed from the cleaning nozzle /t/6 onto the finoletter 20. Then, the cleaning water uses its jet force to peel off the dust adhering to the finoletter 20 from the adhesion surface. Then, since the surface of the finoletter 20 is inclined, the cleaning water containing dust escapes from the front to the back surface and falls without running down the entire surface of the finoletter.

The cleaning pond 7 stops at the position where the cleaning of the finoletter 20 is finished, and then the driving device 4 reverses, and the cart 6 returns to the predetermined position at the start.

As described above, according to this embodiment, by tilting the filter 20, water drainage is improved, and the washing nozzle/
By arranging 1/6 in a straight line and sliding the cleaning nozzle/L/6 by the drive device 4 while spouting cleaning water from a predetermined position away from the filter surface, the number of nozzles can be minimized. It can be done.

As shown in the table below and FIG. 3, there is almost no difference between the cleaning effect and the new filter.

FIG. 4 and FIG. 5 show the cart 5 in the first embodiment.
An air pipe 9 having a large number of air nozzles/L/10 is disposed inside thereof in parallel with a water pipe 6A provided on a straight line intersecting the sliding direction of the trolley 5 in a direction 7 perpendicular to the vane.
A second embodiment is shown in which a compressor 8 for supplying compressed air to this air nozzle/l/10 is connected by a flexible horn 8A.

With this configuration, after the finoletter 20 is placed on the workpiece pedestal 2, the drive device 4 moves the cart 6 on the slide rail lv3, and when the water pipe 6A of the cart 5 approaches the surface of the finoletter 20, cleaning is performed. Cleaning water is jetted out from the cleaning nozzle 6 to clean the finoletter 20. Then, the cart 6 stops at the position where the washing of the finoletter 20 is completed, and at the same time, the jetting of washing water also stops. The drive 4 then reverses and the carriage 6 begins to move in the opposite direction, ie to return. At this time, compressed air is blown out from the air nozzle /l/10 of the air pipe 9, and the fillet is soaked with water from the previous cleaning.
Blows away 20 water. When the truck 6 returns to the starting position and stops, the jetting of compressed air also stops.

According to the second embodiment, the cleaning water contained in the filter 20 after cleaning is immediately blown away, so even if the filter material is water-absorbing, deterioration may occur. It can be dried quickly without any problems.

Common to the first and second embodiments, the holding angle of the work holder 2 of the filter 20 is 4° to 45° in the left-right direction and 4° to 45° in the front-back direction, as shown in FIG. 6 and the table below. If the angle is in the range of 700° to 90°, there will be no difference in the drainage effect.

1. In the embodiment, the cleaning nozzle /L/
6 is attached to the trolley 5, which may slide on the workpiece pedestal 2 that supports the finoletter 20 to be cleaned, and the direction of sliding is left and right in the embodiment. , vertical direction is also acceptable, and there will be no difference in the operation and effect.

As is clear from the explanation of the embodiment described above, according to the present invention, one surface of a dirty fillet is held at an angle opposite to the cleaning nozzle, and that surface is used for cleaning. Since a nozzle is provided and the cleaning nozzle (v1) or the filter holder is mechanically moved, stable cleaning results can be obtained in a constant short time regardless of the temperature or the skill level of the operator.

By blowing the cleaning water with air immediately after cleaning, it is easy to handle the filter after cleaning, the filter furnace material does not have time to absorb water, so it does not deteriorate, and the drying time is significantly reduced. It is possible.
