Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a drain pump.

[Conventional technology]

Conventionally, a drain pump used in an air conditioner is driven by an arrow S in a vertical plane by a motor 7, as shown in the vertical cross-sectional view of FIG. 3 and the horizontal cross-sectional view of FIG.
The lower part of the disc 2 rotating in the direction of is immersed in the drain 6 stored in the drain pan 5, and the upper part of the disc is surrounded as shown by the arrow 8 to cover the drain 6 adhering to the rotating disc 2. The liquid is sprayed along the inner surface of the pump case 1, and is dispersed to the outside from the discharge port 4.

Here, 3 is a partition plate for separating drain that is not discharged from the discharge port 4 but flows backward.

However, this type of drain pump has a structure in which one motor rotates one disk, so if the amount of drain generated by an air conditioner is large, one pump may not have enough capacity and the drain pan will be closed. Sufficient condensate cannot be discharged, and 2
You will need to use a standalone pump, and then,
Due to space issues, it is not possible to make the air conditioner more compact.

[Problem that the invention attempts to solve]

The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide an economical drain pump that can process a large amount of drain and make an air conditioner more compact.

[Means for solving problems]

To this end, the present invention immerses the lower end of a disk disposed on a vertical plane in drain, and rotates the disk around a horizontal axis using a motor to remove the drain adhering to the disk. In a drain pump that discharges water in the circumferential direction and discharges it from a discharge port of a pump case surrounding the upper part of the disc,
It is characterized by a plurality of disks fixed in tandem to the same horizontal shaft rotated by the same motor.

[Effect]

With such a configuration, it is possible to obtain an economical drain pump that can process a large amount of drain and make the air conditioner more compact.

〔Example〕

An embodiment of the present invention will be explained with reference to the drawings.
FIG. 1 is a longitudinal cross-sectional view thereof, and FIG. 2 is a cross-sectional view taken along the line - in FIG. 1.

In the above figure, the same symbols as in Figs. 3 and 4 indicate the same members as in Figs. When installed side by side,
Both discs 2, 2 are fitted in tandem on the rotating shaft of the same motor 7 so as to rotate.

According to this structure, two drain pumps arranged in parallel in the same drain pan are driven by the same motor, so the pump capacity is twice that of the one shown in FIGS. 3 and 4.

The above example shows the case where two pump cases are installed in parallel, but in general, by installing multiple pump cases in parallel and fitting each disc coaxially to the same motor, the capacity of the pump can be increased. Can be increased multiple times without increasing space.

Note that it is also possible to adopt a structure in which a plurality of discs are built into the same pump case, and with such a structure, the installation space can be further reduced.

According to such a structure, the following effects can be achieved.

(1) A compact, lightweight, and large-capacity drain pump can be obtained.

(2) The piping structure around the drain pump becomes simpler.

(3) Air conditioners can be made more compact.

[Effect of idea]

In short, according to the present invention, the lower end of a disk disposed on a vertical plane is immersed in drain, and the disk is rotated around a horizontal axis by a motor, thereby removing the drain adhering to the disk. In a drain pump that discharges water in the circumferential direction and discharges it from the discharge port of a pump case surrounding the upper part of the disc, a plurality of discs are fixed in tandem to the same horizontal shaft rotated by the same motor. According to
The present invention is industrially extremely useful because it provides an economical drain pump that can process a large amount of drain and make the air conditioner more compact.

Claims (1)

[Scope of utility model registration request] The lower end of a disc placed on a vertical plane is immersed in drain, and the disc is rotated around a horizontal axis by a motor, thereby discharging the condensate adhering to the disc in the circumferential direction. What is claimed is: 1. A drain pump configured to discharge fluid from a discharge port of a pump case surrounding the upper part of the disc, characterized in that a plurality of discs are fixed in tandem to the same horizontal shaft rotated by the same motor.
