Description

{Water drain apparatus for drain pumps of air-conditioner}

The present invention relates to a drainage device for an air conditioner drainage pump, and more specifically, to a drainage device for an air conditioner drainage pump that collects condensate and discharges it to the outside when a drainage pump installed in a location where natural drainage of condensate discharged during operation of the air conditioner fails due to an electric leakage, etc., or when excessive discharged water compared to the pump capacity flows into the collection tank, causing the water level to rise above a predetermined limit and causing an overload of the drainage pump to cause an overflow.

In general, air conditioners inevitably generate condensate (hereinafter referred to as “discharge water”) due to the temperature difference between the heat exchanger and the surrounding air during operation. In order to eliminate the inconvenience of having to manually empty the air conditioner discharge water, a separate drain pump is installed to discharge the discharge water from the air conditioner into a sewer or outdoors. More specifically, the discharge water from the air conditioner flows into a collection tank installed inside the drain pump and is then discharged to the outside by a pumping means equipped with a motor and impeller.

And the drainage pump, which operates so that the pumping means stops when the water level in the collection tank is low and starts when the water level is high, is connected to one side of the air conditioner to drain the condensate from the air conditioner. However, if the drainage pump breaks down and overflows due to condensate overflowing, problems such as electric leakage may occur, such as condensate accumulating on the floor.

Therefore, a technology is required to collect the overflowing condensate and forcibly discharge it to the outside when a conventional drainage pump breaks down, and the present invention aims to solve this problem as a technical challenge.

In order to achieve the above purpose, the following detailed description and drawings are provided to explain in detail.

The following is a detailed description, with reference to the attached drawings, so that a person having ordinary knowledge in the technical field to which the present invention pertains can easily implement the technical idea of the present invention.

As shown in FIG. 1 and FIG. 2, the present invention comprises a drainage tank (100) that is connected to the drain of an air conditioner and has a drainage pump (10) for collecting condensate generated by the operation of the air conditioner and sending the collected condensate to the outside, and a receiving space (101) formed inside, and an opening at the top thereof.

A drainage device for an air conditioner drainage pump is provided, which includes a drainage member (200) comprising a drainage pipe (210) connected to a receiving space (101) on one upper side of one side of the periphery of the drainage tank (100) and a drainage line (220) connected to an end of the drainage pipe (210) to discharge condensate collected in the receiving space (101) to the outside.

A conventional drain pump (10) is configured to include, for example, a collecting tank for collecting waste water generated by the operation of an air conditioner, but not shown in the drawing, a motor for driving an impeller for sending the waste water collected in the collecting tank to the outside, a pumping switch connected to the motor via a wire to turn the motor on/off, a float that rises and falls according to the water level in the collecting tank, and a lifting rod connected to the float to open and close the contact of the pumping switch in conjunction with the float. In addition to the pump limited to the structure of the above-described drain pump (10), the above-described drain pump (10) can be applied to a similar drain pump (10).

And, as shown in FIGS. 1 and 2, the drainage device of the present invention is composed of a drainage tank (100) and a discharge member (200), and the drainage tank (100) has an opening at the top to form a receiving space (101) inside, and a drainage pump (10) is received and installed in the receiving space (101). At this time, the receiving space (101) has a cross-sectional area larger than the cross-sectional area of the drainage pump (10), and has a space area capable of collecting condensate overflowing from the drainage pump (10).

In addition, the receiving space (101) of the above-mentioned drainage tank (100) has a rectangular horizontal cross-section, but is not limited thereto and can be manufactured and used in various shapes other than a rectangular shape.

And, the discharge member (200) is connected to a discharge pipe (210) that is connected to the receiving space (101) on one side of the upper surface of the circumference of the drainage tank (100) to discharge condensate collected in the receiving space (101) of the drainage tank (100) to the outside, and protrudes to the outside of one side of the drainage tank (100), and a discharge line (220) that is extended to a predetermined length and has one end connected to an end of the discharge pipe (210) is connected, so that condensate moved through the discharge pipe (210) is moved through the discharge line (220) and discharged to the outside.

In addition, a drainage device for an air conditioner drainage pump is provided, in which a fixing member (110) is formed to connect to the rear edge of the drainage tank (100) and to attach a fixing means (not shown) to a wall surface.

In order to secure the above-mentioned drainage tank (100) to the wall, a fixing member (110) that is protrudingly connected to the rear edge of the drainage tank (100) corresponding to the wall is formed, and a fixing means such as a piece is combined to the fixing member (110) to secure the drainage tank (100) to the wall.

In addition, the upper edge of the above-mentioned drainage tank (100) has a shape in which it is bent to a predetermined length toward the inside of the receiving space, thereby preventing condensate from flying.

In addition, in order to prevent water particles from being scattered by vibration of the drainage pump (10) collected in the receiving space (101) of the drainage tank (100) during operation of the drainage pump (10) accommodated and installed in the receiving space (101) of the drainage tank (100), the following structure may be further included.

As shown in FIGS. 3 and 4, a first buffer (300) having elasticity is further included so as to be settled on the bottom surface of the receiving space (101) of the drainage tank (100) or to be fastened to the lower end of the outer surface of the drainage pump (10), and the lower surface of the drainage pump (10) is brought into contact with the upper portion of the buffer (300), so that the vibration generated during the operation of the drainage pump (10) is absorbed by the first buffer (300), thereby preventing the condensate collected in the receiving space (101) from flying away.

And, instead of the first buffer (300) being settled on the bottom surface of the receiving space (101), the first buffer (300) has an elastic frame (310) that forms a first fastening space (301) on the inside so as to be fastened and attached to the lower end of the outer surface of the drainage pump (10), and a plurality of first elastic bars (320) that protrude horizontally at a predetermined interval from the outer surface of the elastic frame (310) are connected, and the ends of the first elastic bars (320) are structured to be fastened to the inner wall of the receiving space (101) of the drainage tank (100).

The above first buffer (300) is a ring-type buffer having a shape corresponding to the shape of the lower outer circumference of the drainage pump (10) and having a first fastening space (301) formed on the inside, and a plurality of first elastic bars (320) that are connected at one end to the outer circumference of the elastic frame (310) and protrude horizontally are connected at regular intervals, and the other end of the first elastic bar (320) is installed in close contact with the inner wall of the receiving space (101) of the drainage tank (100), and at this time, while inserting the lower part of the drainage pump (10) into the first fastening space (301) of the elastic frame (310), the elastic frame (310) is fastened so that it is positioned on the lower outer circumference of the drainage pump (10), and the elastic frame (310) and the first elastic bar (320) are each formed of a rubber material having restoring force.

In addition, as shown in Fig. 5, the first elastic bar (320) is formed to a length that does not touch the inner wall of the receiving space (101), and the first elastic bar (320) has an empty space inside and an open shape so that the end face is connected to the empty space, and an auxiliary cushion (500) is further included, which is composed of a support body (510) having a larger cross-sectional area than the cross-sectional area of the empty space so that one end can be inserted into the empty space of the first elastic bar (320) and adhered to it, and an inclined elastic bar (520) that is bent upward while one end is connected to the end of the support body (510) exposed by the end of the first elastic bar (320), and the auxiliary cushion (500) is formed by a support body (510) that is inserted and fixed into the empty space of the first elastic bar (320) and an elastic bar (520) that is bent and extended upwardly while one end is connected to the support body (510). It is composed of an inclined elastic bar (520), and the upper end of the inclined elastic bar (520) is positioned so as to be in contact with the upper part of the inner wall of the receiving space (101) of the drainage tank (100). At this time, when the drainage pump (10) is received in the receiving space (101), the inclined elastic bar (520) is formed to be inclined upward between the inner wall forming the inner surface of the receiving space (101) and the outer surface of the drainage pump (10).

Accordingly, the vibration generated by the operation of the drainage pump (10) is transmitted to the support body (510) and the inclined elastic bar (520) through the first elastic bar (320), and is transmitted to the drainage tank through the upper end of the inclined elastic bar (520) that is placed on the upper part of the receiving space (101) and is attenuated.

In addition, the above-mentioned drainage tank (100) may be formed as a double vacuum structure or a double wall structure, and may further serve to attenuate vibration of the drainage pump (10) by being formed as a double vacuum structure having a vacuum space inside or a double wall structure having an empty space inside.

And, as shown in Fig. 4, a grid-shaped anti-flying plate (400) is further included, the outer surface of which is in close contact with the upper outer surface of the receiving space (101) of the drainage tank (100), while a second fastening space (401) is formed on the inner side so as to be fastened to the upper outer surface of the drainage pump (10), and the anti-flying plate (400) is formed in a form in which a plurality of holes are formed while horizontal and vertical plates are arranged in a grid outside the second fastening space (401) on the inner side, and while the upper outer surface of the drainage pump (10) is inserted and fastened into the second fastening space (401), the anti-flying plate (400) is positioned on the upper outer surface of the drainage pump (10), and is placed on the upper end of the receiving space (101) of the drainage tank (100), and at this time, the condensate received in the receiving space (101) is prevented from being fastened by the vibration of the drainage pump (10).

And, as shown in Fig. 6, the second buffer body (600) is comprised of a second elastic bar (610) that is arranged on the bottom surface of the receiving space (101) of the drainage tank (100) and is connected in an “X” shape, and a vertical buffer bar (620) that is connected to each end of the second elastic bar (610) to form a buffer space (621) inside and has a plurality of holes (622) formed on the outer surface that communicate with the buffer space (621), and each buffer bar (620) of the second buffer body (600) has a structure in which it is located at the corner of the inner wall of the receiving space (101).

As the second buffer body (600) is settled on the bottom surface of the receiving space (101) of the drainage tank (100), buffer bars (620) corresponding to each corner of the inner wall of the receiving space (101) are installed in close contact with the corners, and at this time, when the drainage pump (10) is accommodated in the receiving space (101), the buffer bars (620) arranged at the corners of the receiving space (101) come into contact with the corners of the drainage pump (10), and the second elastic bars (610) are settled on the bottom surface of the drainage pump (10).

Accordingly, when the drainage pump (10) is in operation, vibration is absorbed by the second elastic bar (610) and the buffer bar (620) of the second buffer body (600), thereby preventing condensate from flying into the receiving space (101) of the drainage tank (100).

In addition, the drain pump (10) may have a structure in which a second buffer (600) is installed on the floor surface of the receiving space (101) while the first buffer (300) is coupled to the lower outer periphery of the drain pump (10), and at this time, the vibration of the drain pump (10) can be completely absorbed due to the first and second buffers (300) (600).

As described through the above examples, the drainage device for an air conditioner drain pump can be manufactured by changing the design in various ways. Although the principle is limited to the configuration of the present invention through the examples, it is disclosed that a person with ordinary knowledge can easily manufacture the device through design changes based on the principle.
