Description

[Detailed description of the invention] "Industrial application field" This invention relates to a ceiling-mounted air conditioner, and especially when a drain pump is installed on one side of the dew pan, sand, dirt, etc. It provides a structure to prevent the inflow.

"Conventional technology" In conventional ceiling-mounted air conditioners, the outer body of the main body is fixed to a ceiling structure with multiple hanging bolts, and due to the installation position, the indoor heat exchanger As a drainage means for the dew pan, a stepped recess was formed on one side of the dew pan, and a drain pump was mounted on the stepped recess.

However, according to the above conventional structure, the outer body of the main body is attached to a structure in the ceiling, so
It is difficult to maintain and inspect the interior directly from below the ceiling, and if sand or dirt in the drain tray flows into the drain pump, the pump may malfunction.

``Problem to be solved by the invention'' The present invention was devised in view of the above-mentioned drawbacks of the conventional technology.In particular, when a drain pump is installed on one side of the drain tray, sand, dirt, etc. may flow into the pump side. The purpose of this invention is to provide a structure that prevents this from occurring, and also allows it to be easily eliminated if necessary.

"Means for Solving the Problems" As a means of the present invention for solving the above problems, in a ceiling-mounted air conditioner installed on a ceiling structure, etc., one side of the dew pan of the indoor heat exchanger is At the same time, a stepped recess is formed for installing the drain pump, and a bank-like mounting edge is provided around the deepest part of the recess to fit the frame member of the filter of the drain pump. form a drainage ditch,
The drain groove is configured to be closed by a frame member of the filter installed on the mounting edge.

``Embodiment'' The present invention will be described with reference to an embodiment shown in the figure below. 1 is a dew pan disposed directly below the indoor heat exchanger in the outer shell of the main body of an overhead type air conditioner,
This dew pan 1 is made of a heat insulating material such as foamed synthetic resin, and has a stepped recess 2 on one side for mounting a drain pump.
A bank-like mounting edge 4 is protruded around the deepest part 21 of the stepped recess 2 into which the frame member 3 of the filter of the drain pump is fitted. In addition, the required number of drainage grooves 5 are formed on the mounting edge 4,
The drainage groove 5 is configured to be closed by an edge 31 of the filter frame member 3 installed on the mounting edge 4. Further, a suction pipe 6 of the drain pump is attached to the frame member 3 through an opening 32. Further, a drain port is formed in the deepest part 21 of the stepped recess 2, and a drain pipe 7 is installed in this drain port, and a rubber cap 8 is attached to the lower end of the drain pipe 7 that protrudes to the lower part of the dew pan 1. is attached removably.

"Function" In the above configuration, condensed water flows into the dew pan 1 directly below the indoor heat exchanger, and this condensed water collects in the stepped recess 2, but the drain groove 5 of the mounting edge 4 Since the water level is closed by the edge 31 of the frame member 3, the water does not directly flow into the deepest part 21, and when the water level exceeds the mounting edge 4, it flows through the filter of the frame member 3 and flows into the deepest part 21. flows into.
The filter of the frame member 3 can prevent sand and dirt in the dew pan 1 from getting mixed with the condensed water and entering the deepest part 21.

Next, when removing the drain pump for cleaning as required, remove the frame member 3.
The drainage groove 5 on the mounting edge 4 is opened, and sand and dirt mixed in the condensed water flow directly into the deepest part 21 through the drainage groove 5. When the rubber cap 8 is removed in this state, the drain pipe 7 The sand and debris can be easily removed to the outside along with the flow of condensed water drained through the drain.

``Effect of the invention'' As described above, in a ceiling-mounted air conditioner, a stepped recess is formed on one side of the dew pan, and a bank-shaped recess is formed around the deepest part to fit the frame member of the filter of the drain pump. By providing a protruding mounting edge and configuring the drain groove formed on the mounting edge to be closed with the frame member, condensed water flows through the filter during normal operation, so that condensation does not occur on the drain pump side. This prevents sand and dirt from flowing into the water and prevents drain pump failure.

Also, if you wish to clean this as necessary,
By removing the frame member and removing the rubber cap, sand and dirt can be easily removed along with condensed water, improving serviceability.
