[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter cleaning device and a filter cleaning unit for injecting cleaning water into a filter used in an air conditioner, an air conditioner, or the like. The present invention relates to a filter cleaning device and a filter cleaning unit that can dispersively spray and efficiently clean.

[0002]

2. Description of the Related Art Conventionally, as a device for cleaning a filter of an air conditioner, for example, there is a cleaning device proposed in Japanese Utility Model Laid-Open No. 2-100681. As shown in FIG. 9 and FIG. 10, this conventional cleaning device is configured so that a cylindrical shaft d is integrally rotated inside a housing a in a direction perpendicular to a tip of a rotary drive shaft c of a vertically installed drive motor b. A support f having a circular ring shape in plan view is attached to the tips of a plurality of support plates e which are mounted and radially outwardly mounted from the tubular shaft d. The inner peripheral surface of the support f and the tubular shaft are attached. A plurality of mounting protrusions i and j having supporting recesses g and h are respectively fixed to the opposing portions of d, and the mounting recesses g and h of these mounting protrusions i and j are fixed.
In this case, both ends of the object k to be cleaned such as a filter are detachably fitted, the object k to be cleaned is supported, and the cleaning liquid is ejected to the side wall m on one side of the housing a toward the central part of the housing a. It has a structure in which a pipe p having a plurality of nozzles n is arranged.

When cleaning the object to be cleaned, the drive motor b
To rotate the rotary drive shaft c, and integrally rotate the cylindrical shaft d and the support body f together with the rotary drive shaft c, and the mounting protrusion i,
While rotating the object k to be cleaned fitted in the supporting recesses g and h of j in the circumferential direction, from the plurality of nozzles n of the pipe p,
The cleaning liquid is directly ejected toward the object to be cleaned k.

[0004]

However, in the above-mentioned conventional cleaning device, the cleaning liquid is directly ejected from the nozzle n of the pipe p to the cleaning target object k which is rotated and moved by applying a centrifugal force. Since the cleaning liquid is directly applied to the k to clean, there is a problem that the cleaning liquid intensively hits a specific portion of the cleaning target k and is broken.

The present invention has been made in view of the above-mentioned conventional problems, and by spraying the cleaning liquid dispersively toward the filter, the cleaning can be efficiently performed without damaging the filter such as tearing. An object is to provide a filter cleaning device and a filter cleaning unit.

[0006]

The present invention has been proposed to achieve the above object, and a filter cleaning device according to claim 1 cleans a filter used for an air conditioner, an air conditioner or the like. And a transfer means for transferring the filter back and forth while holding the filter horizontally, and a cleaning water installed above the filter transfer path for injecting cleaning water toward the filter. The jetting means, the washing water supplying means for supplying washing water to the washing water jetting means, and the washing water jetting means are reciprocally moved in a direction transverse to the transfer direction of the filter to disperse the washing water in the filter. And a cleaning drainage discharge means for discharging the drainage after cleaning.

According to a second aspect of the present invention, there is provided a swash plate having a swash plate in which the cleaning drainage discharging means extends obliquely downward of a filter transfer path in the main body of the device for receiving cleaning drainage after cleaning. The tank has a tank for temporarily storing the cleaning drainage flowing down along the tank, a drawer-type filter member having a handle removably accommodated in the tank, and a discharge pipe for discharging the drainage in the tank to the outside. It is composed.

The filter cleaning device according to a third aspect of the present invention has a structure in which the filter is transferred in the forward and reverse directions by an operation handle and a transfer roller connected to the operation handle, and a caster is provided at the lower part of the device body. It is composed. The filter cleaning device according to claim 4, wherein the swing mechanism uses a drive motor as a drive source, and a cam mechanism that rotates in response to rotation of the drive motor, and a crank that is coupled to the cam mechanism and moves up and down. , And a motion converting means that is combined with a joint member that is connected to the crank and swings back and forth.

According to a fifth aspect of the present invention, there is provided a filter washing device, which is a slight modification of the filter washing device according to the first aspect.
A plurality of units are arranged in a row through these connecting tools. Here, the first-stage filter cleaning device is a pre-cleaning device that sprays pre-cleaning water toward the filter from the cleaning-water ejecting means, and the second-stage filter cleaning device is The cleaning device disperses the cleaning water toward the filter in a dispersed manner. The filter cleaning device at the third stage is a rinsing device that sprays rinsing water from the cleaning water jetting means at the fourth stage. The filter cleaning device is a drying device that emits drying air instead of the cleaning liquid from the cleaning water jetting means.

[0010]

According to the filter cleaning apparatus of the first aspect, while cleaning the filter by the transfer means, the cleaning water is sprayed from the cleaning water ejecting means toward the filter for cleaning. Since the rocking mechanism reciprocates in the direction transverse to the transfer direction of the filter, the sprayed cleaning water is dispersed in the form of a spray, so that the entire range of the filter can be cleaned. Further, since the washing water does not concentrate on a specific portion of the filter, the filter is not broken and damaged.

According to the filter cleaning device of claim 2,
The cleaning waste water after cleaning is received by the swash plate, falls along the swash plate, and is temporarily stored in the tank. Then, the washing wastewater is filtered while being dropped from the swash plate into the tank, is filtered by a filter member arranged in the tank, is stored downflow, and is discharged to the outside through a discharge pipe. According to the filter cleaning device of claim 3, the transfer roller can be reciprocally and reciprocally rotated by the rotation operation of the operation handle so that the filter can be reciprocally reciprocally moved. You can focus on the cleaning while reversing.

Further, since the caster is provided in the lower part of the main body of the apparatus, the entire apparatus can be transported to a desired place according to the purpose of work. According to the filter cleaning device of claim 4, when the drive motor is driven, the cam mechanism is rotated, the crank is moved up and down, and the vertical movement of the crank causes the joint member to swing back and forth to inject the cleaning water. The means are reciprocated in a direction transverse to the transport direction of the filter. As a result, the cleaning water sprayed from the cleaning water spraying means is sprayed in the form of fine mist and hits the filter surface uniformly and widely. Therefore, even if the injection pressure of the wash water is increased, it is dispersed, so that the wash can be efficiently performed.

According to the filter cleaning unit of the fifth aspect, when cleaning the filter, the preliminary cleaning device in the first stage sprays the preliminary cleaning while transferring the filter by the transfer device of each device. Then, after preliminary cleaning, in the second-stage cleaning device, cleaning water is sprayed from the cleaning water spraying means to clean. After that, in the rinsing device of the third stage, the rinsing water is sprayed from the rinsing water spraying means to rinse the rinsing water attached to the filter, and finally the fourth rinsing device.
In the drying device of the stage, the filter is dried by the dry heating air discharged from the washing water jetting means. In this way, with each device arranged in series, the filter
Pre-washing, washing, rinsing, and drying can be performed as a work flow, and dirt attached to the filter can be removed to obtain a clean state.
