Description

Technical Field

[0001] The utility model relates to the technical field of ice making machines, in particular to a micro ice making machine. Background Art

[0002] An ice maker is a refrigeration mechanical device that generates ice by cooling water through an evaporator using the refrigerant in the refrigeration system. A micro ice maker is a small mini ice maker that is convenient for use when traveling or outings.

[0003] Publication number: CN219243992U discloses a mini ice maker with high stability, including an ice maker body, an ice box is slidably installed in the ice maker body, and a take-out mask with the same height as the ice box is embedded on the side of the ice maker body, the inner wall of the take-out mask is provided with a mounting groove, and a swing rod is rotatably installed in the mounting groove. The mini ice maker with high stability starts the liquid pump when making ice, so that the water in the small water tank is transported to the liquid dispenser through the liquid pump and the conduit, and finally injected into the ice box through the injection head. The ice box is stored in the ice maker body for refrigeration. After ice making is completed, the servo motor starts and drives the screw to rotate, so that the connecting block drives the driving block to slide to the right on the limit shaft. In this process, the smooth convex ball hits the body cover, so that the body cover swings outward around the swing rod to release the body cover from blocking the take-out mask, and then the ice box is moved to the outside of the ice maker body to take out the granular ice.

[0004] The applicant found that there are some deficiencies in use: when the air cooler blows out cold air to make ice, if a certain amount of water remains in the dispenser and the injection head, the ice will be frozen during the making process, thus affecting the next injection.

[0005] Therefore, the utility model designs a miniature ice maker to solve the problems existing in the prior art. Utility Model Content

[0009] Preferably, a hollow frame is installed on the top of the fixed plate, and a plurality of nozzles are provided on the inner wall of the hollow frame. A heater connected to the hollow frame is provided above one side wall of the chassis. When the ice making time is long and a certain degree of agglomeration occurs in the dispenser and the injection head, the heater can be started and the nozzles can spray hot air to quickly defrost.

[0010] Preferably, slide plates are installed on both inner walls of the chassis, and limiting grooves for slidingly mounting the slide plates are opened on both side walls of the mold, so that the mold can be easily put in and taken out through the slide plates and the limiting grooves.

[0011] Preferably, the four top corners of the dispenser are connected to the top inner wall of the chassis via telescopic rods. The lifting of the dispenser causes the telescopic rods to extend and retract, and the telescopic rods are limited by the dispenser to improve the stability of the lifting of the dispenser.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model is provided with an anti-icing mechanism. After the injection head is filled with water, the electric cylinder drives the liquid dispenser to rise to a position above the fixed plate, and then the screw drives the isolation plate to move. The two isolation plates block the square grooves, reducing the rise of cold air to the top of the chassis, thereby reducing the icing of the liquid dispenser and the injection head, avoiding affecting the next injection. If the ice making time is too long and the liquid dispenser and the injection head are frozen to a certain extent, the hot air blower can also be started to make the nozzle spray hot air to quickly defrost the liquid dispenser and the injection head.

[0026] Working principle: When making ice, the electric cylinder 101 drives the dispenser 7 to descend, so that the injection head 8 descends to a suitable position above the mold 9 to prevent water from splashing out. Then the water in the insulated water tank 2 enters the dispenser 7 and then enters the mold 9 through the injection head 8. Then the air nozzle 5 blows out cold air to make ice from the water in the mold 9. Making ice requires a certain amount of time. In order to prevent residual water in the dispenser 7 and the injection head 8 from freezing and affecting the next injection, the electric cylinder 101 raises the dispenser 7 to the top of the fixed plate 102, and then the screw 105 drives the isolation plate 106 to move. The two isolation plates 106 seal the square groove 103 to reduce the cold air from entering the top of the fixed plate 102, thereby reducing the solidification of the injection head 8 and avoiding affecting the next injection. If a certain degree of solidification occurs, the heater 109 can be started to make the nozzle 108 blow hot air to accelerate the melting of the ice in the dispenser 7 and the injection head 8.
