Detailed Embodiments

[0022] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this article are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0025] Referring to Figure 1 、 Figure 2 and Figure 3 , the present utility model discloses a drainage tank 10 assembly, including a water tank 10, a water pump 20 and a water level detector 30. A first water inlet 12 and a drain outlet 11 are provided on the water tank 10, and the first water inlet 12 and the drain outlet 11 are communicated with the water tank 10. The water level detector 30 is installed in the water tank 10, and the water level detector 30 is used to detect the water level height in the water tank 10 and send a water level signal. In addition, the water pump 20 is arranged in the water tank 10, and the water outlet of the water pump 20 is communicated with the drain outlet 11 through a drain pipe 40; the water pump 20 can be started or stopped according to the water level signal.

[0026] Based on the above structure, when using the drainage tank 10 assembly of the present utility model, the drainage tank 10 assembly can be used in equipment such as ice makers, refrigerators, heat pumps, etc. that require drainage to discharge system wastewater.

[0027] Taking the application of the drainage tank 10 assembly to an ice maker as an example, the first water inlet 12 of the water tank 10 can be communicated with the condensate outlet of the ice maker through a water pipe. During the operation of the ice maker system, the generated condensate is continuously introduced into the water tank 10 through the first water inlet 12, and the water level in the water tank 10 continuously rises. When the water level detector 30 detects that the water level in the water tank 10 reaches the set height, the water level detector 30 can send a water level signal to control the start of the water pump 20. When the water pump 20 starts, it can discharge the water in the water tank 10 through the drain pipe 40 to the drain outlet 11, so that the water in the water tank 10 can be automatically discharged to prevent water overflow.

[0028] Of course, it should also be noted that during the continuous drainage of the drain port 11, the water level in the water tank 10 will drop. When the water level detector 30 detects that the water level has dropped to the set level, the water level detector 30 can also send a water level signal to control the water pump 20 to stop, thus preventing the situation of the water pump 20 running dry.

[0029] Specifically, a controller can be set up. The controller is electrically connected to the working circuit of the water pump 20 and is used to receive the water level signal detected by the water level detector 30 to control the start and stop of the water pump 20.

[0030] Furthermore, a first check valve is provided in the drain port 11. The first check valve can guide the water flow to be discharged unidirectionally, thus preventing the wastewater from flowing back and realizing the check valve function of the drain port 11.

[0031] Furthermore, a second check valve is provided in the first water inlet 12. The second check valve can guide the water flow to be introduced unidirectionally. In this way, even if the water in the water tank 10 is full, the introduced water cannot overflow from the first water inlet 12, that is, it can realize water overflow prevention when full and realize the check valve function of the first water inlet 12.

[0032] Furthermore, an exhaust port is provided on the water tank 10. The exhaust port is in communication with the water tank 10, and an exhaust pipe 14 is connected to the exhaust port. In this way, when the wastewater is introduced into the water tank 10, the gas inside the water tank 10 can be gradually discharged through the exhaust port, preventing the internal air pressure of the water tank 10 from being too high and affecting the introduction of the wastewater.

[0033] Furthermore, a second water inlet 13 is provided on the water tank 10. The second water inlet 13 is in communication with the water tank 10, and the second water inlet 13 can collect the wastewater introduced from other containers, such as the wastewater in the ice bucket during the ice-taking process, etc.

[0034] Furthermore, the water level detector 30 is a float type water level switch in the prior art. The float type liquid level switch uses the magnetic float of the float type liquid level switch to move up or down with the liquid level and act on the reed switch chip at the set position in the sensor detection tube of the float type water level switch, sending out a contact open (close) conversion signal to realize water level detection.

[0035] The specific structure and working principle of the specific float type water level switch both belong to the prior art and do not belong to the technical content to be protected by this application, so they will not be elaborated in detail here. In this application, the start and stop actions of the water pump 20 are controlled by the float type water level switch, without a mechanical connecting part 19, and the operation is simple and reliable.

[0036] Of course, the water level detector 30 can also be selected as other detection structures such as a liquid level sensor in the prior art to achieve the function.

[0037] Further, the water tank 10 in this embodiment includes a box body 16 and a box cover 15. The box cover 15 is detachably sealed on the top end of the box body 16, and a sealing ring 70 is clamped between the box cover 15 and the top end of the box body 16. Both the first water inlet 12 and the drain port 11 are provided on the box cover 15. In this way, after the water tank 10 is used for a period of time, the box cover 15 is opened to clean the inside of the box body 16, reducing the breeding of bacteria or the generation of peculiar smell caused by the residual dirt inside the water tank 10 when discharging wastewater. And the sealing ring 70 between the box cover 15 and the box body 16 can prevent water leakage after the water tank 10 is assembled.

[0038] Further, a protruding shell 18 and a first wire passing hole 17 through which the circuit of the water supply pump 20 passes can be provided on the box cover 15. An avoidance cavity communicating with the box body 16 is provided inside the protruding shell 18. After the box cover 15 is sealed to the top end of the box body 16, the protruding shell 18 corresponds to the water level detector 30. In this way, the top end of the water level detector 30 can extend into the avoidance cavity to prevent interference between the assembly of the box cover 15 and the assembly of the water level detector 30.

[0039] In addition, a second wire passing hole 181 is provided on the side wall of the protruding shell 18, and the circuit of the water level detector 30 passes out through the second wire passing hole 181, which is convenient for leading out the circuit of the water level detector 30 inside the water tank 10 and facilitating wiring.

[0040] Further, to facilitate the assembly of the box body 16 and the box cover 15, a first connecting column 161 protrudes from the outer side wall of the box body 16, and a second connecting column 151 is provided corresponding to the outer side wall of the box cover 15. Threaded holes are provided on both the first connecting column 161 and the second connecting column 151. The second connecting column 151 and the first connecting column 161 are correspondingly arranged. By screwing bolts into the threaded holes of the first connecting column 161 and the second connecting column 151, the detachable connection between the box cover 15 and the box body 16 is realized.

[0041] Of course, the tail of the bolt can pass through the bottom end of the threaded hole of the second connecting column 151, and a nut is screwed on to achieve limit and prevent the bolt from detaching.

[0042] In addition, the first connecting column 161 and the second connecting column 151 can also be detachably connected by other connecting parts 19 such as rivets and pins.
