Description

[Detailed Description of the Invention] The present invention relates to a drain processing device for an air conditioner.

One of the drain treatment devices in conventional air conditioners
An example is shown in FIG. 1. Drain 07 that condenses and drips on the surface of the evaporator 06 and is stored in the drain pan 05 is splashed onto the pump case 02 when the splasher 01 is rotated in the direction of the arrow. The water flows around the inner upper part of 02, flows into the gutter 03 disposed around it, is collected, and is taken out from the outlet 04.

An example of a conventional humidifying device for an air conditioner is shown in FIG. 2, in which water 013 supplied to a drain pan 012 is splashed and splashed onto a condenser 014 by rotating a splasher 011 in the direction of the arrow. It evaporates on this surface and humidifies the indoor air.

However, in the conventional apparatus described above, a splasher and a splasher are used separately to collect condensate condensed on the surface of the evaporator 06, and to splash water onto the condenser 014 and evaporate it to humidify the indoor air. Since a motor was installed to drive the
There were problems in that the cost increased and separate installation spaces were required.

The present invention was proposed to solve the above problems, and its gist is that the drain in the drain pan is splashed onto the pump case by a rotating splasher, and the splashed drain is removed from the drain pan. A drain processing device for an air conditioner that is taken out from an outlet, wherein the splasher is capable of forward and reverse rotation, and an opening is provided on the side surface of the pump case on the indoor heat exchanger side. located in the drain treatment equipment.

Since the present invention has the above-mentioned configuration, it is possible to splash the drain in the drain pan onto the pump case and take out the drain by rotating a single splasher in the normal direction, and it is also possible to take out the drain by rotating the same splasher in the reverse direction. Accordingly, the water supplied into the drain pan can be evaporated by splashing onto the indoor heat exchanger through the opening provided on the side surface of the pump case. Therefore, only one splasher and its driving device are required, and the structure is simplified and can be manufactured at low cost, requiring less installation space.

Hereinafter, the present invention will be explained in detail with reference to an embodiment shown in FIGS. 3 to 5. 3 is a schematic sectional view taken along the line - in FIG. 4, FIG. 4 is a schematic plan view, and FIG. 5 is a view taken along the line - in FIG. 4. In Figures 3 to 5, 2
1 is a splasher, 22 is a pump case, 23
is the gutter, 24 is the drain outlet, 25 is the drain pan,
26 is an indoor heat exchanger, 27 is a drain or water supply,
28 is a motor, and 30 is an opening provided on the side surface of the pump case 22 on the indoor heat exchanger 26 side.

The splasher 21 is rotated in the X direction during cooling when the indoor heat exchanger 26 functions as an evaporator, and rotates in the Y direction during heating when the indoor heat exchanger 26 functions as a condenser. When the splasher 21 rotates in the X direction, the drain 27 in the drain pan 25 is scattered as shown by the broken line, and when the splasher 21 rotates in the Y direction, the water supply 27 in the drain pan 25 passes through the opening 30 of the pump case 22 and flows out as shown by the dashed line. As shown in the figure, the particles start to scatter.

Thus, during cooling operation, the indoor heat exchanger 26 functions as an evaporator, and due to its cooling action, moisture in the air condensed on its surface becomes drain and drips into the drain pan 25 and accumulates therein. During the cooling operation, the splasher 21 is driven to rotate in the X direction, causing the drain 27 in the drain pan 25 to be scattered as shown by the broken line. Then, this scattered drain hits the upper part of the pump case 22, flows down along its inner surface, is collected in a gutter 23 protruding from the inner surface, and flows out from the outlet 24.

During heating operation, the indoor heat exchanger 26 functions as a condenser and reaches a high temperature. Then, water is supplied into the drain pan 25 from the outside for humidification. Therefore, by rotating the splasher 21 in the Y direction, the water 27 in the drain pan is splashed through the opening 30 of the pump case 22 and splashed onto the indoor heat exchanger 26, as shown by the two-dot chain line. The splashed water evaporates because the indoor heat exchanger 26 is at a high temperature, and the indoor air is humidified.

The drain treatment device of the present invention can be used for discharging the drain 27 during cooling operation, and can be used as a humidifier by splashing water supply 27 onto the condenser 26 during heating. During cooling operation, potential energy is required to flow the drain 27. Therefore, the splasher 21 splashes the drain onto the pump case 22, collects it through the gutter 23, and transfers the drain to the drain pan 2.
5 and the gutter 23.

In addition, the drain pump of the present invention is often used in ceiling-mounted air conditioners, so it is necessary to dispose of drain by passing it over obstacles such as pillars in the ceiling.
Potential energy of the drain is required, and according to the present invention, this potential energy can be given to the drain.
