Abstract

PURPOSE:To clean and remove dust sticking to a heat exchanger by a drain without decomposing the outer casing of an air-conditioner by providing a water storage tank for storing generated drain in an air-conditioner outer casing such that it is located above a heat exchanger, and pouring the drain in the water storage tank onto the heat exchanger through a water supply pipe and a control valve. CONSTITUTION:Air sucked into an air-conditioner outer casing 1 by a fan 2 is cooled as it passes through a heat exchanger 3, and generated drain is recovered by a drain pan 5. The drain stored in a water storage tank 7 provided on the inner top part of the air-conditioner outer casing 1 by a drain pump 4 and sucked up passes through the water storage tank 7 and is discharged to the outside via a discharge pipe 6. When dust sticks to the heat exchanger 3, a control valve 8 is opened to pour the drain in the water storage tank 7 onto the heat exchanger 3 for cleaning of the heat exchanger 3. Hereby, there is eliminated the need of decomposing the air-conditioner outer casing for exposing the heat exchanger to the outside and hence cleaning is always possible, and further cleaning work can be automated only by opening the control valve.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air conditioner, and more particularly to a means for cleaning a heat exchanger using condensate produced by the heat exchanger.

[Prior Art] Fig. 2 is a vertical sectional view showing an air conditioner disclosed in Japanese Utility Model Application Publication No. 61-194109.
1] is the outer casing of the conditioner, (2) is the blower, (3) is the heat exchanger, (4 is the drain pump, (5) is the drain pan that receives dripping drain from the heat exchanger, and (6) is this This is a drain pipe that discharges the drain pumped up from the drain pan to the outside of the conditioner outer casing (1).

Next, the operation will be explained. The air sucked into the harmonizer outer casing (1) by the blower (2) is cooled as it passes through the heat exchanger (3), and the drain generated at this time is collected in the drain pan (5) and sent to the drain pump (4). ) is discharged to the outside of the conditioner outer casing (1) via the drain pipe (6).

The dust that has adhered to the heat exchanger (3) due to the above operation must be removed by disassembling the lower part of the outer casing (1) of the conditioner, exposing the heat exchanger (3) inside, and cleaning it separately. It has become.

[Problem to be solved by the invention] Since the conventional air conditioner is configured as described above,
There was a problem in that the outer casing of the conditioner had to be disassembled each time the heat exchanger was cleaned, and cleaning was time-consuming.

This invention was made to solve the above problem, and the dust that adhered to the heat exchanger is cleaned and removed without disassembling the outer casing of the conditioner, using the drain generated in the heat exchanger. The purpose is to

[Means for Solving the Problems] The air conditioner according to the present invention includes a water storage tank for storing generated drain, which is provided in the outer casing of the conditioner so as to be located above the heat exchanger. The drain water is sprinkled onto the heat exchanger via a water supply pipe and a control valve.

[Function] In the air conditioner according to the present invention, the drain generated in the heat exchanger is stored in a water storage tank, and this drain is sprinkled on the heat exchanger as desired. There is no need to disassemble the harmonizer outer casing, and cleaning is done automatically.

[Example] An example of the present invention will be described below. In Sunarichi Figure 1, the same parts as in Figure 2 are given the same reference numerals and duplicate explanations will be omitted, but (7 in Figure 1)
is a water storage tank in this invention for storing drain pumped up from a drain pan (5) by a drain pump (4), and this tank is located above the heat exchanger (3) in the outer case of the conditioner (1). ) is provided at the inner top of the (8) is a control valve for selectively supplying the drain in the water storage tank (7) into the harmonizer outer casing (1); ) is a water supply pipe for sprinkling water on top.

Next, the operation will be explained. The air sucked into the outer casing (1) of the conditioner by the blower (2) is cooled as it passes through the heat exchanger (3), and the drain generated at this time is collected in the drain pan (5) and sent to the drain pump ( 4), the drain is collected in a water tank (7) provided at the inner top of the conditioner outer casing (1), and the drain that is usually pumped up passes through the water tank (7) and is discharged to the outside via the drain pipe (6). be done. When dust adheres to the heat exchanger (3) during the above operation, the control valve (8) is opened and the drain in the water tank (7) is drained from the water supply pipe (9).
), water is sprayed onto the heat exchanger (3) to clean it.

[Effects of the Invention] As described above, the air conditioner of the present invention collects condensate generated in a heat exchanger in a water storage tank, and sprays the condensate over the heat exchanger to clean the heat exchanger. This eliminates the need to disassemble the harmonizer outer casing and expose the heat exchanger, as was the case in the past.

It has the advantage that it can be cleaned at any time while it is in the same state, and that the cleaning work can be done automatically just by opening the control valve.
