Description

Wastewater drainage pumps for air conditioners incorporating water level switches

The present invention is related to the waste water drainage pump of the air conditioner, in particular to a waste water drainage pump for the air conditioner equipped with a water level switch.

Currently known waste water drainage pumps for air conditioners, such as the separated air conditioners used in general households, if the installation position of the indoor unit cannot be provided with pipelines to guide downwards to the drainage channel, the condensed waste water generated during operation will be A waste water drain pump is required. In order to achieve the effect of easy installation and reduced volume, conventional wastewater drainage pumps usually cover the motor with a casing, and then use the motor to drive the drainage blades to absorb water and drive drainage in the lower casing. The mutual cooperation of the drainage vanes and the lower casing can discharge the condensed waste water generated during the operation of the air conditioner to the outside. For example, the No. I701389 patent of my country's announcement discloses a waste water drainage pump for an air conditioner.

Currently known waste water drainage pumps for air conditioners are usually detected by a water level switch. The water level switch is usually installed independently of the waste water drainage pump when installed, and then connected to the internal main body with wires. The control circuit board is used for setting, so that when the water level is high, the waste water drainage pump is started to operate for drainage, and when the water level is low after continuous operation, the waste water drainage pump is turned off.

However, due to the water level detection of the water level switch, the setting of the water level must be determined according to the height of the relevant components of the waste water drainage pump. The high water level cannot be higher than the motor, otherwise there will be a problem of short circuit of the wires, and the low water level cannot be low. For the water inlet of the lower casing, otherwise there will be a problem that the drainage blades cannot absorb water and cause idling.

It can be seen from the above that the water level switch and the wastewater drainage pump are inseparable in use and setting. Therefore, the conventional technology separates the water level switch and the wastewater drainage pump, which is a waste of space and more troublesome in setting.

The problem encountered by the prior art is that the water level switch and the waste water drainage pump are installed separately, which wastes the assembly space, and when setting the water level, the height must be determined according to the relationship between assembly and the position of the motor and the lower casing. Water level and low water level, therefore, setting the water level is also relatively troublesome.

The main purpose of the present invention is to provide a waste water drainage pump for an air conditioner equipped with a water level switch. The water level switch and the waste water drainage pump can be assembled together, which not only saves the overall space, but also saves the overall space when setting the water level.

The ends of the two long arms 33 form a hook portion 331, and the two long arms 33 form a hook portion 331. The arms 33 respectively form a positioning groove 332 from the end to the rear of the hook portion 331, and the two long arms 33 form a slider 333 outward respectively, as shown in Figures 2 and 3, the positioning of each of the long arms 33 In this embodiment, the slot 332 is formed by the hook portion 331 of each long arm 33 facing the sliding block 333 . The set of joints 42 forms a slide groove 433 on both sides respectively, and one end of the two slide grooves 433 on both sides of the set of joints 42 is open, which can be used for the slide block 333 of the two long arms 33 to slide. Into, the group joint 42 forms two positioning blocks 432 at the other end of the two sliding slots 433, and can be embedded in the positioning slots 332 of the two long arms 33 respectively, and is held by the respective positioning blocks 432 of the two long arms 33. The hook portion 331 is hooked.

In the above structure, the body of the water level switch 41 passes between the two long arms 33 from bottom to top. In addition, the set of joints 42 has a through hole 44 , the water level switch 41 has two electrode rods 46 connected to the buoy 48 , and the two electrode rods 46 pass through the through hole 44 and are exposed above the set of joints 42 . It should be noted here that the water level switch 41 of the present invention has two electrode rods 46 , which is a very cheap conventional water level switch 41 , so there is a need for the two electrode rods 46 to pass through the through hole 44 . And when using other kinds of water level switches 41 , it is possible not to have the configuration of the two electrode rods 46 , and such water level switches 41 do not have the requirement that components need to pass through the through holes 44 .

In addition, in this first embodiment, the joint seat 32 is integrally formed on the cover body 31 as an example, but the joint seat 32 does not necessarily have to be formed on the cover body 31 in fact. In an aspect, the assembly socket 32 can also be formed on the main casing 21 or on the lower casing 11 , depending on actual needs. And the technique of forming the connecting seat 32 on the main casing 21 or the lower casing 11 can be directly understood by referring to the state of being arranged on the cover body 31 in the first embodiment, so it is not included in the figure expression.

The configuration of the present first embodiment has been described above, and the operation state of the present first embodiment will be described next.

As shown in FIG. 3 , when the water level switch 41 is to be combined with the cover body 31 , the assembly joint 42 of the water level switch 41 is assembled to the assembly socket 32 of the cover body 31 . When assembling, make the openings of the two chute 433 of the group joint 42 align with the slide blocks 333 on both sides of the two long arms 33 of the group joint 32, and then move the group joint 42 towards the group joint 32 to make the sliders 333 on both sides of the two long arms 33 enter the two chute 433 , at the same time, the hooks 331 at the ends of the two long arms 33 also pass through the two chute 433 . Next, as shown in Figure 4, the hooks 331 at the ends of the two long arms 33 will first abut against the two positioning blocks 432 of the joint 42. In actual implementation, the front ends of the hooks 331 can be set according to requirements. The two long arms 33 are tilted downward due to the abutting relationship, and then the two positioning blocks 432 slide past the tops of the two hooks 331, and then enter the two positioning grooves of the two long arms 33. 332, the two hooks 331 hook the two positioning blocks 432, and the state shown in FIG. 5 is formed. So far, the assembly of the water level switch 41 and the cover 31 is completed. In addition, it can be seen from FIG. 6 and FIG. 7 that the relationship between each component of the assembly socket 32 and the assembly joint 42 is in the assembled state.

As shown in Figures 3 to 5, when the water level switch 41 is to be separated from the cover body 31, the above-mentioned operations are performed in reverse order, and the hooks 331 at the ends of the two long arms 33 are first pressed down so that the two long arms 33 The arm 33 is forced to swing downward, so that the hooks 331 at the ends of the two long arms 33 no longer catch the two positioning blocks 432. At this time, the group joint 42 is moved outwards away from the group joint seat 32, so that The two positioning blocks 432 press the hooks 331 at the ends of the two long arms 33. At this point, you can directly hold the group of joints 42 to move outwards, and the sliders 333 on both sides of the two long arms 33 move along the two slide grooves. 433 deviates from the open end until the hooks 331 of the two long arms 33 disengage from the two slide grooves 433 to complete the separation.

It can be seen from the above that the water level switch 41 of the present invention is assembled on the cover body 31 in a detachable manner, which not only saves the overall space, but also because the two are assembled together when setting the water level, it is different from the reference motor and the lower casing. The position of 11 is extremely convenient when determining the water level. In addition, since it is assembled in a detachable manner, it is very convenient to disassemble and maintain.
