Description

[0001] The present invention relates to a washing apparatus for system air conditioner,

The present invention relates to a cleaning apparatus for a system air conditioner, and more particularly, it relates to a cleaning apparatus for cleaning a system air conditioner installed at a high position using a lifting unit, It can be cleaned by rotating 360 ° at the center of the floor, and steam, water, detergent and compressed air can be selectively sent to the places where it needs to be cleaned. And to enable a worker to work at a safe distance from the washing water.

The air conditioner sucks the surrounding hot air, converts it into cool air through the coolant, and turns it back into the room. It sucks indoor air so that it absorbs the dust contained in the indoor air. . The filter is installed to prevent the bad air in the room from circulating through the air conditioner, but it does not cover bacteria that are invisible ultra-fine particles. These bacteria accumulate inside the air conditioner as well as the system air conditioner. If you do not remove it, it will harm the health of the residents.

System air conditioner means a product that uses several indoor units in one outdoor unit. Generally, the indoor unit is installed on the ceiling to maximize the utilization of the space.

Figure 1 shows a conventional way of cleaning the system air conditioner.

FIG. 1B is a photograph showing a state in which the internal components of the system air conditioner are separated from the ceiling and then cleaned. FIG. 1C is a photograph showing a system air conditioner And FIG. 1D is a photograph of the operator cleaning the system air conditioner installation part in which the system air conditioner is removed between the vinyl films.

Referring to FIGS. 1A and 1B, conventionally, all of the system air conditioners installed on the ceiling are separated from the ceiling, and then they are washed, dried, and then assembled on the ceiling. Although the system air conditioner can be cleaned reliably, separation and reassembly is difficult for the average person to do, so it is natural that it will have to be referred to a specialist and it will cost considerably.

Referring to FIGS. 1C and 1D, a system for installing a system air conditioner, that is, a system air conditioner installation unit, is shown. In this process, there is a problem that the operator is exposed to the air-conditioner washing water. In addition to the system air conditioner, the system air conditioner installation part includes the harmful bacteria which can not be imagined by the general public. Therefore, it is disadvantageous that the cleaning worker is exposed to the washing water.

In addition, since it is not easy to install vinyl to collect the washing water, the size of the space where the system air conditioner is installed may be different, and the edge of the vinyl and the edge of the portion to be cleaned must be sealed by using the adhesive means, Reuse has the disadvantage of being quite difficult or difficult.
