Description

Technical Field

[0001] This utility model relates to the field of air conditioner drainers, and in particular to an air conditioner drainer. Background Technology

[0002] During the air conditioning cooling process, water vapor in the indoor air condenses upon contact with cold air, forming condensate. To ensure proper operation, the air conditioner installed indoors must collect this condensate and discharge it through a specific method. In existing drainage systems, the water pump and circuit board are housed in the same space; if the water pump leaks, it can easily damage the circuit board. Furthermore, the water pump typically relies on a water level probe to detect the water level in the storage tank and starts accordingly. However, over time, scale can accumulate on the surface of the water level probe, affecting its detection accuracy and potentially leading to false starts of the water pump. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an air conditioner drainer.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An air conditioner drainer includes a water storage tank with an inlet and an outlet. It is characterized by further comprising a first mounting cavity and a second mounting cavity that are not interconnected. A water pump is installed in the first mounting cavity, with its intake port connected to the water storage tank and its outlet connected to the outlet. A circuit board for controlling the water pump's operation (opening and closing) is installed in the second mounting cavity, and the circuit board includes a magnetic switch. A start switch is installed in the water storage tank, comprising a float and a magnetic component connected to the float. The magnetic component reciprocates between a first position and a second position as the float rises and falls.

[0006] When the magnetic component is in the first position, the magnetic component approaches the magnetic switch, causing the magnetic switch to be in a closed state, thereby starting the water pump.

[0007] When the magnetic component is in the second position, the magnetic component moves away from the magnetic switch, causing the magnetic switch to be in an open state, thereby turning off the water pump.

[0008] Furthermore, the start switch also includes a connecting rod, a swinging component, and a fixed box. The middle part of the connecting rod is pivotally connected to the fixed box, the float is connected to one end of the connecting rod, one end of the swinging component is pivotally connected to the fixed box, the magnetic component is disposed at the other end of the swinging component, and the other end of the connecting rod is drively connected to the swinging component.

[0009] Furthermore, the fixing box has an opening at the position corresponding to the swing trajectory of the magnetic component, and also includes a spring, the two ends of which are respectively connected to the connecting rod and the swing component.

[0010] Furthermore, it also includes an mounting base and a fixing base. The mounting base is connected to the water storage tank through the fixing base. The mounting base has a first mounting cavity and a second mounting cavity, and the mounting base also has a third mounting cavity for mounting the fixing box.

[0011] Furthermore, it also includes a filter screen, which is installed in the water storage tank to divide the water storage tank into an inlet chamber and an outlet chamber, with the inlet connected to the inlet chamber and the outlet connected to the outlet chamber.

[0012] Furthermore, a buffer pad is provided between the water pump and the fixed base.

[0013] Furthermore, the buffer pad has a fixed edge, and the fixed seat has a snap-fit ​​groove that is adapted to the fixed edge.

[0014] Furthermore, the buffer pad is provided with a mounting groove, and the water pump is provided with a sealing adapter at one end of the water inlet and the water outlet that fits into the mounting groove.

[0015] Furthermore, it also includes a first connecting pipe and a second connecting pipe.

The bottom wall of the mounting groove is provided with a first through hole and a second through hole for the first connecting pipe and the second connecting pipe to pass through.

[0016] Furthermore, the water storage tank includes a tank body and a tank cover, the tank cover is provided with the water inlet and the water outlet, and the water inlet is provided with an isolation net.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model proposes an air conditioner drainer, comprising a first mounting cavity and a second mounting cavity that are not interconnected. The first mounting cavity houses a water pump, and the second mounting cavity houses a circuit board. During use, even if the water pump leaks due to a malfunction, it will not damage the circuit board, reducing losses. Simultaneously, the water level probe is optimized into a start-up switch with a float. Compared to a water level probe that monitors the liquid level via an electrical signal, the float rises and falls with the liquid level, driving a magnetic component to reciprocate between a first and a second position. That is, the float drives the magnetic component through a mechanical structure. Even if scale accumulates on the surface of the float, it will not affect the float's driving force on the magnetic component, thus ensuring the accuracy of water level monitoring and reducing the probability of the water pump starting erroneously.

[0019] 2. The present invention proposes an air conditioner drainer, wherein a buffer pad is provided between the water pump and the fixed base to reduce the noise generated by the water pump due to vibration.

[0020] 3. The air conditioner drainer proposed in this utility model also includes a filter screen, which is installed on the outer side of the fixed base to prevent impurities from entering the water pump; at the same time, an isolation screen is provided at the water inlet to prevent impurities from entering the water storage tank.

Detailed Implementation

[0031] The following is combined Figures 1-8 This utility model will be described in detail.

[0032] An air conditioner drainer includes a water storage tank with an inlet 101 and an outlet 102. It is characterized by further including a first mounting cavity 301 and a second mounting cavity 401 that are not interconnected. A water pump 70 is installed in the first mounting cavity 301, with its intake port connected to the water storage tank and its outlet connected to the outlet 102. A circuit board 80 for controlling the opening and closing of the water pump 70 is installed in the second mounting cavity 401, and the circuit board 80 is equipped with a magnetic switch. A start switch 90 is installed in the water storage tank, comprising a float 901 and a magnetic component 905 drivenly connected to the float 901. The magnetic component 905 reciprocates between a first position and a second position as the float 901 rises and falls.

[0033] When the magnetic component 905 is in the first position, it approaches the magnetic switch, causing the magnetic switch to close, thereby starting the water pump 70. Figure 4 As shown;

[0034] When the magnetic component 905 is in the second position, it moves away from the magnetic switch, causing the magnetic switch to be in the off state, thereby shutting off the water pump 70. Figure 5 As shown.

[0035] Since the water pump 70 and the circuit board 80 are located in two separate, unconnected mounting cavities, even if the water pump 70 leaks due to a malfunction, it will not damage the circuit board 80, thus reducing losses. Simultaneously, the water level probe is optimized into a start switch 90 with a float 901. Compared to the water level probe monitoring the liquid level via electrical signals, the float 901 rises and falls with the liquid level, driving the magnetic component 905 to reciprocate between a first and second position. That is, the float 901 drives the magnetic component 905 through a mechanical structure. Even if scale accumulates on the surface of the float 901, it will not affect the float 901's driving of the magnetic component 905, thereby ensuring the accuracy of water level monitoring and reducing the probability of the water pump 70 starting erroneously.

[0036] In this embodiment, the start switch 90 also includes a connecting rod 902, a swing member 903, and a fixed box 904. The middle part of the connecting rod 902 is pivotally connected to the fixed box 904. The float 901 is connected to one end of the connecting rod 902. One end of the swing member 903 is pivotally connected to the fixed box 904. The magnetic member 905 is disposed at the other end of the swing member 903. The other end of the connecting rod 902 is connected to the swing member 903.

[0037] In this embodiment, the fixed box 904 has an opening 9041 at the position corresponding to the swing trajectory of the magnetic component 905 to reduce the influence of wall thickness on magnetic flux; it also includes a spring 906, the two ends of which are respectively connected to the connecting rod 902 and the swing component 903. Further, it also includes a mounting base and a fixing base 50. The mounting base is connected to the water storage tank via the fixing base 50. The mounting base has a first mounting cavity 301 and a second mounting cavity 401. The mounting base includes a first mounting base 30 and a second mounting base 40. The first mounting base 30 has a first mounting cavity 301, and the second mounting base 40 has a second mounting cavity 401. The first mounting base 30 and the second mounting base 40 can be separately formed or integrally formed. The outer side of the second mounting base 40 also has a third mounting cavity 402 for mounting the fixed box 904, such as... Figure 8 As shown.

[0038] In this embodiment, a filter screen 601 is also included. The filter screen is installed in the water storage tank 20, thereby dividing the water storage tank 20 into an inlet chamber and an outlet chamber. The inlet 101 is connected to the inlet chamber, and the outlet is connected to the outlet chamber. The water storage tank includes a tank body 20 and a tank cover 10. The tank cover 10 is provided with an inlet 101 and an outlet 102, and an isolation screen 103 is provided at the inlet 101. The tank body 20 is used to store condensate. The isolation screen 103 is used to prevent impurities from entering the water storage tank, and the filter screen 601 prevents impurities from entering the outlet chamber. The isolation screen 103 and the filter screen 601 provide dual filtration to ensure the stable operation of the water pump 70.

[0039] In this embodiment, a buffer pad 100 is provided between the water pump 70 and the fixed base 50 to alleviate noise generated by the vibration of the water pump 70. Furthermore, the buffer pad 100 has a fixed edge 1001, and the fixed base 50 has a snap-fit ​​groove 501 adapted to the fixed edge 1001. Furthermore, the buffer pad 100 has a mounting groove 1002, and the sealing of the water pump 70's inlet and outlet ends is adapted to fit within the mounting groove 1002.

[0040] In this embodiment, a first connecting pipe 1101 and a second connecting pipe 1102 are also included. The drain outlet of the water pump 70 is connected to the outlet 102 of the water storage tank through the first connecting pipe 1101. The pump outlet extends to the bottom of the water storage tank 20 through the second connecting pipe 1102. The bottom wall of the mounting groove 1002 is provided with a first through hole 1201 and a second through hole 1202 for the first connecting pipe 1101 and the second connecting pipe 1102 to pass through.

[0041] The working principle of the air conditioner drainer proposed in this embodiment is as follows:

[0042] When the air conditioner is not turned on, the float 901 is in a downward state under the action of gravity. The spring 906 pulls the swinging component 903, causing the magnetic component 905 to swing to the second position. Figure 5 As shown, at this time, the magnetic component 905 is away from the magnetic switch in the second position and puts the magnetic switch in the open state, thereby turning off the water pump 70.

[0043] After the air conditioner is turned on, condensate is generated and enters the water storage tank through the isolation net 103 of the inlet 101. When the water level in the storage tank reaches a certain height, the float 901 rises with the liquid level, and the spring 906 pulls the swinging component 903, causing the magnetic component 905 to swing to the first position. Figure 4 As shown, when the magnetic component 905 is in the first position, it approaches the magnetic switch and closes the magnetic switch, thereby turning on the water pump 70.

[0044] In this embodiment, the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
