Description

Technical Field

[0001] The utility model relates to the field of ice makers, and specifically to a spherical ice making structure of an ice maker. Background Art

[0002] An ice maker is a refrigeration mechanical device that cools water through an evaporator by a refrigerant of a refrigeration system to generate ice. The existing spherical ice making structure of an ice maker mainly includes an upper ice maker mold, a lower ice maker mold, a skating board, a sandwich tube, an evaporator, a water storage tank, and a servo motor. The top of the upper ice maker mold is arranged below the sandwich tube, the lower ice maker mold is arranged above the evaporator, and the opposite sides of the upper ice maker mold and the lower ice maker film are provided with hemispherical ice making grooves. The skating board leans against the opening and closing position of the upper mold and the lower film. During ice making, water is evenly sprayed into the ice making grooves of the ice maker from the water storage tank through the evaporator by a water pump. Refrigerant flows through the sandwich tube. After the water flows through the wall surface of the ice maker, it is cooled to the freezing point to form spherical ice cubes. During ice removal, the servo motor drives the water storage tank, the evaporator, and the lower ice maker mold to rotate. The upper ice maker mold and the lower ice maker mold are opened. The skating board falls under the influence of gravity and covers the lower ice maker mold. Hot air is introduced into the sandwich tube. The ice cubes in the ice making grooves of the upper ice maker mold fall off and roll into the ice collection box below along the skating board. Since the length of the skating board is limited by the opening distance between the upper ice maker mold and the lower ice maker mold, the skating board cannot completely cover the ice making grooves of the lower ice maker mold. When the ice cubes in the upper ice maker mold fall off, the ice cubes at the end of the upper mold may fall into the unclosed ice making grooves on the lower mold and cannot continue to be demolded along the skating board. This will reduce the number of ice making per time. After long-term use, the upper ice maker mold and the lower ice maker mold cannot be completely closed, affecting normal use. Summary of the Utility Model

[0003] In view of the defects existing in the existing spherical ice making structure of an ice maker, the technical problem to be solved by the utility model is to provide a spherical ice making structure of an ice maker that can avoid ice cubes falling into the ice making grooves of the lower ice maker mold after ice removal and has high ice making efficiency.

The surfaces of the upper ice maker mold 1 and the lower ice maker mold 2 are coated with an anti-corrosion and heat-conducting material. The upper ice maker mold 1 is arranged below the fixing frame 9. A sandwich pipe 3 is fixed to the top of the upper ice maker mold 1. The lower ice maker mold 2 is fixed to the top of the evaporator 4, and the bottom of the ice-making groove of the lower ice maker mold 2 is open. One end of the water storage tank 5 is hinged to the fixing frame 9, and the other end is connected to the servo motor through a stroke control mechanism 8. The evaporator 4 is fixed to the top of the water storage tank 5. A number of groups of water spraying holes 10 and water leakage holes 11 are provided on the top of the evaporator 4. The opening of the ice-making groove of the lower ice maker mold 2 is opposite to the water spraying holes 10 and the water leakage holes 11 on the evaporator 4. The guiding mechanism 7 and the skating mechanism 6 are arranged below the fixing frame 9 and are respectively arranged on both sides of the upper ice maker mold 1. The skating mechanism 6 includes a skating board 12, a bracket I13, a limiting rod 14, and a gravity rod 15. The limiting rod 14 is fixed in the middle of the bracket I13. The skating board 12 is hinged to the bottom of the bracket I13, and a gravity rod 15 is provided on the skating board 12. The guiding mechanism 7 includes a guiding plate 16, a rocker arm I17, a rocker arm II18, and a bracket II19. One end of the upper part of the guiding plate 16 is hinged to one end of the rocker arm I17, and the other end extends outward with a sliding rod 20. The bracket II19 is arranged on both sides of the guiding plate 16, and a sliding groove 21 is provided at the bottom of the bracket II19. The sliding rod 20 is inserted into the sliding groove 21. The end of the rocker arm I17 that is not connected to the guiding plate 16 is hinged to the bracket II19. One end of the rocker arm II18 is hinged to the middle of the rocker arm I17, and the other end is hinged to the water storage tank 5. Through the cooperation of the rocker arm I17 and the rocker arm II18, the guiding plate 16 can be made to move along the sliding groove 21.

[0022] Please refer to Figure 1 , Figure 5, a spherical ice-making structure of an ice maker provided in this embodiment. During ice making, the upper ice maker mold 1 and the lower ice maker mold 2 are fitted together, and the ice-making grooves of the two are spliced to form a spherical cavity. The skating board 12 abuts against the end of the water storage tank 5, and the skating board 12 leans against the limit rod 14. The guide plate 16 is abutted by the lower ice maker mold 2 and is at the highest point of the sliding groove 21. The water pump pumps water from the water storage tank 5 through the evaporator 4 and then evenly sprays it into the ice-making groove of the ice maker through the water spraying holes 10. Refrigerant flows through the sandwich pipe 3. Since the surfaces of the upper ice maker mold 1 and the lower ice maker mold 2 are coated with an anti-corrosion and heat-conducting material, the sandwich pipe 3 can quickly cool the upper and lower ice maker molds. The water flows through the wall surface of the ice-making groove and is cooled to the freezing point to form spherical ice cubes. The excess water flows back into the water storage tank 5 through the water leakage holes 11; during ice removal, the servo motor rotates to drive the stroke control mechanism 8 to move the water storage tank 5 and the lower ice maker mold 2 away from the upper ice maker mold 1 and tilt downward. During the tilting process, the water storage tank 5 will abut against the gravity rod 15. Under the action of the gravity rod 15, the skating board 12 tilts towards the lower ice maker mold 2 and covers the lower ice maker mold 2. At the same time, the tilting of the water storage tank 5 drives the rocker arm II 18 to displace. The guide plate 16 slides downward along the sliding groove 21 under the cooperation of the rocker arm I 17 and the rocker arm II 18, and finally is above the part of the lower ice maker mold 2 not covered by the skating board 12. Hot air is introduced into the sandwich pipe 3. After the ice cubes in the ice-making groove of the upper ice maker mold 1 fall off, they will land on the guide plate 16 or the skating board 12. The ice cubes landing on the guide plate 16 will roll down along the guide plate 16 to the skating board 12, and finally all enter the ice collection box below, which can effectively prevent some ice cubes from falling into the ice-making groove of the lower ice maker mold 2 after ice removal, and avoid the situation that the upper ice maker mold 1 and the lower ice maker mold 2 cannot be completely fitted due to the residual ice cubes in the ice-making groove.

For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
