Description

Technical Field

[0001] The utility model relates to the technical field of ice makers, in particular to a load protection mechanism for an ice maker. Background Technique

[0002] The working principle of an ice maker is based on refrigeration technology. By heating water above the melting point and then rapidly cooling it, the water solidifies into ice cubes. An ice maker usually consists of a compressor, a condenser, an evaporator, refrigerant, and a control system, etc. The compressor compresses low-temperature and low-pressure gas into high-temperature and high-pressure gas, and then dissipates heat through the condenser and cools it into high-pressure liquid. The high-pressure liquid enters the evaporator through an expansion valve.

[0003] For example, the patent application number disclosed on the Chinese Patent Network is: 202022756112.3, and the patent name is: Load protection mechanism for an ice maker. The flipping water box is rotatably connected to the housing of the ice maker through a rotating shaft. The ice maker further includes a flipping motor for driving the flipping water box to rotate around the rotating shaft. An induction component is also provided on the ice maker, and the induction component is connected to the controller of the ice maker, and the controller is connected to the flipping motor. When the induction component senses that the flipping water box rotates to a predetermined position, the controller controls the flipping motor to stop flipping. The induction component includes a microswitch provided on the housing of the ice maker, and the microswitch is connected to the controller. The beneficial effect of the utility model is that it can protect the flipping motor when the flipping water box of the ice maker exceeds a certain amplitude.

[0004] However, the existing load protection methods for ice makers are relatively single, and can only limit the flipping angle of the water box. When the weight of the ice cubes in the ice box is too high, the continuously injected liquid water box will overflow, resulting in moisture inside the ice maker and short circuit. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem of overflow and short circuit caused by continuous ice making of the water box in the prior art, and to propose a load protection mechanism for an ice maker.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0010] An ice box is provided inside the ice making body. The ice box is movably connected to the ice making body through a lifting structure. The valve core of the water valve is fixedly connected to a transmission rod. One end of the transmission rod away from the water valve penetrates to both sides of the water valve and is fixedly connected to a sleeve plate. One side of the sleeve plate away from the transmission rod extends to both sides of the ice box through the bottom of the water tank. Slide rods are fixedly connected to both the left and right sides of the ice box.

[0020] Compared with the prior art, the utility model provides a load protection mechanism for an ice maker, which has the following beneficial effects:

[0025] 5. For this load protection mechanism of the ice maker, by setting a bracket and a bearing plate, the water tank can be buffered and the water tank can be supported stage by stage.

[0026] 6. For this load protection mechanism of the ice maker, by setting a rubber pad, the impact force generated when the water tank falls can be weakened, avoiding the water tank directly colliding with the bearing plate.

[0027] 7. For this load protection mechanism of the ice maker, by setting an elastic plate, the bearing plate can be supported, enabling the bearing plate to have an elastic reset effect.

[0028] 8. For this load protection mechanism of the ice maker, by setting a drainage pump and a hose, the melted liquid inside the ice box can be discharged, reducing the influence of the liquid on the ice cubes.

[0029] 9. For this load protection mechanism of the ice maker, by setting a window frame and a viewing window, it is convenient for users to observe and master the ice quantity.

[0030] 10. For this load protection mechanism of the ice maker, by setting a baffle, the sealing effect of the ice maker body can be improved, reducing the pollution of the external environment to the ice box. BRIEF DESCRIPTION OF THE DRAWINGS
