Abstract

The present invention relates to a drainage of a ceiling type air conditioner. The drainage includes a water tank, two or more automatic aspiring pumps, and drainpipes connected to the pumps. The pumps are disposed on the two-inclined end of the water tank or around the water tank. With this drainage, one of the pumps on the end of the water tank or around the water tank can always contact the condensed water, regardless the inclination direction of the water tank. So the condensed water can be discharged in time, preventing the water from being accumulated and overflow.

Description

Ceiling type air conditioner drainage device

The utility model relates to a ceiling type air conditioner, in particular to a ceiling type air conditioner drainage device. Background technique

In many buildings that are stationary, such as shopping malls, office buildings, large conference rooms, etc., ordinary ceiling-type air conditioners are usually used for cooling. The indoor units are mainly composed of heat exchangers, turbo fans, and drainage devices. The drainage device (shown in Figure 1) is mainly composed of a water storage tank 10, a single automatic water pump 12, a drain pipe 13, and the like. The turbo fan draws in air. When the air passes through the heat exchanger, the temperature is lowered. The water vapor in the air is condensed into liquid water and dripped into the reservoir. When the condensate in the reservoir reaches a certain height, the automatic pump will Automatically turned on to drain the condensate. However, in many devices where the state of motion is often changed, the ceiling-type air conditioner indoor unit drainage device cannot meet the requirements. For example, a boarding bridge, which often needs to be docked with a different type and height of aircraft through the lifting and lowering of the lifting device at its front end, so that the air-conditioning indoor unit installed thereon will not always be level, often along with the boarding bridge. Tilting up or down a certain angle, referring to Figure 1, the air conditioner indoor unit reservoir 10 will also be inclined. When the tilt direction is as shown in Fig. 1, the automatic pump 12 cannot pump the air conditioning condensation product inside the reservoir 10. The water 11 will eventually cause the accumulated water 11 to pass through the drain pipe 13 and overflow the reservoir 10, and drip into the boarding bridge to affect passengers and other facilities passing through. The same problem can occur in other sports equipment equipped with this ceiling air conditioner. It is therefore necessary to provide a new drainage device to solve this problem. Utility model content

The technical problem to be solved by the utility model is to provide a ceiling type air conditioner drainage device, which can effectively solve the phenomenon of water accumulation and overflow in the indoor storage tank of the sports equipment air conditioner in the prior art.

In order to achieve the above object, the utility model provides a ceiling type air conditioner drainage device, which comprises a water storage tank, an automatic water pump and a drainage pipe connected with the automatic water pump, wherein the automatic water pump is at least two. And are respectively disposed at both ends or around the reservoir.

The above-mentioned ceiling type air conditioner draining device is characterized in that the water storage tank is a water storage tank of a sports equipment air conditioner indoor unit, and the automatic water pump is disposed at two ends or four sides in a direction in which the water tank is inclined. The above-mentioned ceiling type air conditioner draining device is characterized in that two of the automatic pumping pumps are symmetrically disposed at opposite corners of the water storage tank along the center of the water storage tank.

The above-mentioned ceiling type air conditioner drain device is characterized in that the drain device is applied to a boarding bridge. The above-mentioned ceiling type air conditioner draining device is characterized in that the bottom end suction port of the automatic water pump is a predetermined distance from the bottom of the water tank.

After adopting such a device, when the air-conditioning reservoir is tilted in any direction, the automatic pumping pump disposed at both ends or around the reservoir always has a pump that is in contact with the accumulated water, so that the condensed water can be extracted in time without generating A large amount of water and overflow.

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but not to limit the invention. DRAWINGS

1 is a schematic view of an air conditioning drainage device in the prior art;

Figure 2 is a positional view of the pump of the air conditioning drainage device of the present invention;

Figure 3 is a cross-sectional view of the air conditioning and drainage device of Figure 2. detailed description

In Fig. 2 and Fig. 3, two automatic pumps 22a, 22b having identical structures are symmetrically distributed along the center at two opposite corners of the reservoir 20, and a drain pipe 23a is connected to the top end of the automatic pump 22a. 24a is at a distance from the bottom of the reservoir 20. Of course, the automatic pumping water pumps 22a, 22b may also be disposed at two ends or around the water storage tank 20. For sports equipment such as boarding bridges and refrigerating vehicles, the direction in which the motion equipment is tilted may be set. Both ends or the periphery of the upper storage tank, so that when the accumulated water is inclined to one side, the pump can be pumped by the side. For example, in a sports equipment such as a boarding bridge, when the boarding bridge is tilted up or down to dock with the aircraft, the air conditioning condensate water will be biased to one side, when the air conditioning condensation water is biased to the side shown in Figure 3. The suction port 21⁄2 of the pump 22a on the left side does not come into contact with the accumulated water 21, and the pump does not operate. The suction port 24b of the pump 22b on the right side is in contact with the accumulated water 21, and once the accumulated water 21 reaches a certain defined height, the pump 22b starts to operate, and the accumulated water 21 is taken out from the reservoir 20 and discharged to the gate through the drain pipe 23b. Outside the bridge. By the same token, when the boarding bridge is tilted in the other direction, the pump 22a on the left side will operate to drain. In this way, the reservoir 20 will not produce water and overflow. Other sports equipment such as large refrigerated vehicles that travel on the road The multi-pump drain can also work normally to achieve the same effect.

Without departing from the spirit and scope of the present invention, one of ordinary skill in the art can make various changes and modifications in accordance with the present invention. For example, three, four or more can be installed around the cistern 20. Pumps are used to achieve this effect, but such corresponding changes and modifications are intended to fall within the scope of the appended claims.
