Description

Combined air conditioner drainage pump

Technical Field

The utility model relates to a combined air conditioner drainage pump.

Background

The drain pump of the air conditioner is a device for discharging moisture generated inside the air conditioner by a combination type drain pump of the air conditioner. During operation of the air conditioner, moisture in the air may be condensed into water droplets, which may flow out through a drain pipe inside the air conditioner. However, if the height of the drain pipe is insufficient or the length of the pipe is too long, water cannot naturally flow out, and thus the drain pump of the air conditioner is required to pump out and drain the water. The air conditioner drain pump is usually arranged on a drain pipeline in or near the air conditioner, and can automatically sense the water level and start pumping.

The problem of water leakage is particularly remarkable in the use process of the air conditioner drainage pump, and the water leakage of the air conditioner drainage pump is caused by the following reasons: 1. drain pipe blockage: if the drainage pipeline is blocked, water can flow back to the drainage pump, so that water is accumulated in the pump body, and water leakage is caused. 2. Poor seal of drain pump: poor sealing of the drain pump can also result in water leakage. If the seal is not tight, water can seep out of the interface of the pump body. 3. Drain pump aging: the drain pump has long service life, and sealing elements and parts in the pump body can age, so that water leakage is caused. 4. Improper installation of the drain pump: if the drainage pump is improperly installed, such as incorrect installation angle or unstable installation position, water flow inside the pump body is not smooth, and water leakage is caused. 5. Drain pump failure: if the drain pump itself fails, such as a motor failure or impeller failure, water leakage may result.

In response to the above problems, when a water leakage phenomenon occurs, the following steps are generally adopted to repair the water leakage problem: 1. closing the power supply of the air conditioner: before maintaining the drain pump, the air conditioner power supply is turned off first to avoid electric shock accident. 2. Disassembling the drainage pump: the drain pump is detached, and whether the pump body is cracked or damaged is checked, and if so, a new drain pump needs to be replaced. 3. Cleaning a drainage pump: sundries in the drainage pump are cleaned up, including scale, dirt and the like in the pump body, so that the drainage effect is not affected. 4. And (3) replacing a sealing ring: if the sealing ring of the drainage pump is aged or damaged, the sealing ring needs to be replaced in time so as to avoid leakage. 5. Checking a drainage pipeline: the drain pump may leak because the drain pipe is clogged or broken, and it is necessary to check whether the drain pipe is normal. 6. Installing a drainage pump: the cleaned drain pump is reinstalled inside the air conditioner, taking care of the installation location and direction. 7. Testing drainage effect: and restarting the air conditioner power supply, testing whether the drainage effect is normal, and if the water leakage phenomenon exists, re-checking the drainage pump and the drainage pipeline.

As can be seen from the above, when the water leakage problem occurs in the drain pump of the air conditioner, the processing method is complicated, and usually the drain pump needs to be disassembled or replaced, if the water leakage problem occurs in the drain pump, the corresponding accessory needs to be replaced, and if the water leakage problem occurs in the pump body of the drain pump, the replacement needs to be performed. The above-mentioned treatment process usually requires a professional to go to the gate for operation. For some high-end precise air conditioners and situations where the use situation is important, such as a refrigerator and the like, the water leakage phenomenon of the drainage pump may cause great economic loss.

The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a combined air conditioner drain pump includes at least two or more trigger drain pumps 1. The trigger type drain pump 1 is an automatic drain device which can automatically sense the height of water level, when the water level reaches a certain height, the pump is automatically started, the water pump is discharged, and when the water level is reduced to a certain degree, the pump is automatically stopped. The trigger type drain pump 1 according to the present utility model includes, but is not limited to, the above description, and other manners such as electric control, trigger sensing, etc. may be adopted.

As shown in fig. 2, the present utility model is exemplified by two drain pumps 1. The two drain pumps 1 are commonly connected with a water tank 2 for balancing. Compared with the water storage space 3 in the pump body of the water pump, the water tank 2 has larger volume and can store more condensed water discharged by the air conditioner. Through a plurality of drain pump 1 setting on water tank 2, improved the storage capacity of comdenstion water on the one hand, on the other hand can also play the counter weight effect through drain pump 1 for air conditioner drain pump 1 can have better stability, prevents drain pump 1 skew mounted position under the exogenic action.

One side of the pump body is provided with a water inlet 4, and the water inlet 4 is arranged in the water tank 2 and communicated with the water tank 2. When the liquid level in the water tank 2 rises to be communicated with the water inlet 4, condensed water can enter the water storage space 3 of the pump body, and when the liquid level reaches a certain degree, the trigger switch drives the water discharge. Wherein the air conditioner water outlet is communicated with the water tank 2 and not directly communicated with the water inlet 4. The condensed water generated by the air conditioner passes through the water tank 2, and then rises through the liquid level of the water tank 2 to enter the water storage space 3.

A water level triggering unit 5 is arranged in both drainage pumps 1. When the water level rises to a designated position, the water level triggering unit 5 triggers the driving drain pump 1 to perform a drain operation. When one of the drainage pumps 1 leaks water or has other faults, an operator can directly shut down the drainage pump 1 for sealing treatment, so that the whole continuous operation can be ensured without waiting for maintenance personnel to go on the gate for maintenance.

As shown in fig. 3 and 4, the distances between the two water level triggering units 5 and the bottom of the water tank 2 are H1 and H2, respectively. H1 and H2 are different in size. Let H1 be smaller than H2 so that when the water level rises to the position corresponding to H1, the drain pump 1 is started, thereby making the drain pump 1 drive the drain. When the drainage pump 1 breaks down, the water level corresponding to the H1 fails, the water level continues to rise until the height of the H2 water level, so that the other drainage pump 1 starts drainage, and the effect of continuously playing the role of drainage after simple treatment when the drainage pump 1 breaks down is achieved.

Above-mentioned, if correspond a plurality of drain pumps 1, then corresponding H1, H2, H3 … … presents the echelonment and arranges to adopt the normal realization of its drainage function of assurance form more.

The water level triggering unit 5 comprises an upright post 6, and a floating ball 7 is arranged on the upright post 6 in a sliding manner. Wherein, the floating ball 7 and the upright post 6 are respectively provided with a Hall element 8 and a magnetic ring 9. When the water level rises to the position of H1, the floating ball 7 floats upwards, so that the Hall element 8 and the magnetic ring 9 are mutually induced, and the drainage pump 1 is started to drain. The above is one solution of the present utility model, but not limited to this, but it is also possible to use the floating ball 7 in an electrical communication or other inductive drain pump 1.

Correspondingly, when the water inlet speed of the water tank 2 is high, the water level rising speed exceeds the water outlet speed of the single water outlet pump 1, and the water level reaches the position of H2, so that the two water outlet pumps 1 jointly operate to carry out water outlet, and the water outlet efficiency is enhanced. Therefore, the corresponding air conditioner does not need to be matched with the power model of the drainage pump 1, so that the corresponding combined air conditioner drainage pump 1 has better suitability.

When the water inlet speed of the water tank 2 is smaller, and the water level rising speed is lower, the single drainage pump 1 can sufficiently drain condensed water when the water level reaches the height of H1, so that a better drainage effect is achieved.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
