Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a drain-up pump for an air conditioner.

[0002]

2. Description of the Related Art When an air conditioner with a drain pan such as a fan coil unit is installed in a ceiling, it is necessary to connect a drain drain pipe in the ceiling and a drain pan of the air conditioner to drain the drain discharged from the air conditioner. There is. However, if there are various obstacles below the drain pan in the ceiling, the drain drain pipe may not be piped with a slope. In such a case, a drain drain pipe is provided to avoid an obstacle, and the drain of the air conditioner is pumped up to the position of the drain drain pipe to be drained. A drain-up pump is used for pumping.

[0003]

However, in the conventional drain-up pump, since the drain discharged from the air conditioner is directly pumped up, there is a problem that the pump is broken by foreign matters contained in the drain. Then, an object of the present invention is to provide a drain up pump which solves the above-mentioned problems.

[0004]

In order to achieve the above object, a drain-up pump according to the present invention is provided with a support member fixed to an air conditioner, detachably attached to the support member, and discharged from the air conditioner. A container for storing the drain that has been drained, a filter for filtering the drain is provided detachably inside the container, and a pump body that pumps up the filtered drain in the container is provided on the support member. Things.

[0005]

FIG. 1 is a simplified view showing an example of use of a drain-up pump according to the present invention. The drain-up pump 1 is provided on a side surface of an air conditioner 2 installed in a ceiling A. The pumping pipe 5 of the drain up pump 1 is connected to the drain drain pipe 4 having a slope. 3 is a drain outlet of the air conditioner 2.

As shown in FIGS. 2 and 3, the drain-up pump 1 includes a support member 6 fixed to the air conditioner 2 and a drain member detachably attached to the support member 6 and discharged from the air conditioner 2. And a container 7 for storing the water.

[0007] Inside the box-shaped container 7 opening upward,
A filter 8 for filtering drain is provided detachably. Specifically, a first tank 10 and a second tank 11 through which water can pass through a filter 8 are formed in a container 7 in a horizontal direction.

The filter 8 is formed in a flat plate shape, and a pair of concave grooved guide portions 12, 12 through which the filter 8 can be inserted and removed from above are formed in the container 7. This guide part 1
The partition between the first tank 10 and the second tank 11 formed by the filters 2, 12 and the filter 8 is formed one step lower than the upper end surface of the container 7. The support member 6 and the container 7 are configured to be detachable by screws or various hanging members.

The support member 6 includes a pump body 9 for pumping the filtered drain in the container 7, a liquid level controller 14 for controlling the operation of the pump body 9, and a water level detector 15 for detecting an upper limit water level excess. Are provided.

The pump body 9 is disposed in the first tank 10, and the pumping pipe 5 is connected to the discharge port 13 of the pump body 9 in communication. The drain drain port 3 of the air conditioner 2 is arranged in the second tank 11. The liquid level controller 14 and the water level detector 15 are composed of a float switch and other liquid level sensors. Inform the operator of the malfunction or both.

According to the present invention, the drain of the air conditioner 2 is drained to the second tank 11 and the drain filtered by the filter 8 flows into the first tank 10 and rises to a predetermined water level. Automatically starts the operation of the pump body 9,
The drain is pumped up to the drain drain pipe 4 and discharged.

When the drain is discharged and falls to a predetermined water level, the operation of the pump body 9 is automatically stopped by the liquid level controller 14. When the drain cannot be pumped due to a failure or the like, the water level detector 15 detects the air conditioner 2.
Operation can be stopped to prevent drain overflow.

The present invention is not limited to the above-described embodiment, and the design can be freely changed without departing from the gist of the present invention. For example, if the water level detector 15 is disposed in the second tank 11, even if the filter 8 does not filter due to clogging or the like, foreign matter in the drain can be prevented from flowing from the second tank 11 to the first tank 10, The pump body 9 can be protected.

[0014]

According to the present invention, the foreign matter contained in the drain can be removed by the filter 8, so that no foreign matter enters or adheres to the pump body 9, and the failure of the pump body 9 caused by the foreign matter can be prevented. At the same time, clogging of the pumping pipe 5 sent from the pump to the drain drain pipe 4 can be prevented, and the maintenance frequency can be reduced. Since the container 7 has a filter, there is no need to provide a separate strainer or the like, and space can be saved. By simply attaching and detaching only the filter-equipped container 7, the washing or the replacement of the filter can be performed, and the handling is easy even in a narrow ceiling.
