Description

Technical Field

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

[0002] With the improvement of urban living standards, the need for portable, portable ice cubes for keeping food cold or drinks cool at family gatherings and outdoor gatherings is increasing. Refrigerators are no longer sufficient to meet these needs. Home ice makers, offering environmentally friendly and energy-saving advantages that reduce the need to frequently purchase ice, are becoming increasingly popular. Experiments have shown that the fuzzy white color of ice cubes is caused by the simultaneous freezing of the water surrounding the popsicle sticks and the air trapped within. This results in ice cubes containing air bubbles, which not only lack a crystal-clear texture but also result in uneven texture, poor hardness, and easy melting. The evaporation temperature of the evaporator also has a very important influence on the transparency of the ice cube. When the evaporation temperature is higher (above -10 degrees Celsius), the longer it takes for the water around the ice column to freeze, the less likely the air contained in the water will be frozen into the ice at the same time, and the transparency of the ice cube will be higher, but this will come at the expense of time; on the contrary, when the evaporation temperature is lower (below -15 degrees Celsius), if the water around the ice column cannot reach a certain movement speed, the shorter the time it takes for the water around the ice column to freeze, the more likely the air contained in the water will be frozen into the ice at the same time, and the lower the transparency of the ice cube.

[0003] Currently, to improve the transparency and uniformity of ice cubes produced by ice makers, a water stirring mechanism is generally installed in the ice box. A motor drives a stirring rod to stir the water, creating a certain fluidity in the water inside the ice box and improving the transparency and uniformity of the ice cubes. However, the water stirring mechanism used in this method is relatively complex and requires a separate motor to drive it. Moreover, the stirring effect is not ideal, and bubbles still remain in the produced ice cubes, resulting in poor transparency and uniformity. Therefore, an ice making machine is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an ice-making machine, which solves the technical problems that the water stirring mechanism in the existing ice-making machine is relatively complex in structure, needs to be driven by a separate motor, and the stirring effect is not ideal, bubbles still exist in the ice cubes produced, and the transparency and uniformity of the ice cubes produced are poor.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figure 1 and Figure 2As shown, in order to achieve the above purpose, the utility model provides an ice-making machine, including: an ice-making box 1 and a circulating water stirring mechanism arranged in the ice-making box 1; wherein the ice-making box 1 is used to contain ice and water, providing a place for ice making.

[0028] An evaporator 2 is provided on the top of the ice box 1. A refrigerant is provided inside the evaporator 2. The evaporator 2 converts the refrigerant from liquid to gas to absorb heat for cooling. The evaporator 2 further transfers the temperature to the circulating water in the ice box 1, while lowering the ambient temperature in the ice box 1. The circulating water in the ice box 1 gradually freezes and forms ice.

[0029] A circulating water stirring mechanism is provided in the ice box 1. The water supply port 10 and the water extraction port 11 of the circulating water stirring mechanism are both provided in the ice box 1. The circulating water stirring mechanism supplies water into the ice box 1 through the water supply port 10 and the circulating water stirring mechanism supplies water into the ice box 1 through the water extraction port 11, thereby providing circulating water into the ice box 1. Specifically, the circulating water stirring mechanism includes: an inlet pipe 4, the upper end of which is the water supply port 10. The upper end of the inlet pipe 4 is provided in the ice box 1, and water is supplied to the ice box 1 through the inlet pipe 4; and a return pipe 3, the upper end of which is the water extraction port 11. The upper end of the return pipe 3 is provided in the ice box 1, and water in the ice box 1 is sucked through the return pipe 3.

[0030] When in use, the evaporator 2 works to convert the refrigerant from liquid to gaseous state to absorb heat for refrigeration. The evaporator 2 transfers the temperature to the circulating water in the ice box 1. The circulating water in the ice box 1 gradually freezes and forms. The ice mold 9 provides a freezing point to the water body, accelerating the rapid solidification of the water body into ice cubes. While the circulating water stirring mechanism provides circulating water to the ice box 1, it can also play a certain stirring role on the water body in the ice box 1, thereby increasing the flow speed of all the water in the ice box 1 while freezing. When the temperature of the evaporator 2 is low, the air in the water body is still difficult to be frozen into the ice, effectively reducing the bubbles in the ice cubes and improving the transparency and uniformity of the ice cubes.

[0031] In one embodiment of the present invention, an ice mold 9 is provided on the outer wall of the evaporator 2 and is located within the ice making box 1. The ice mold 9 provides a freezing point for the water, accelerating the rapid freezing of the water into ice cubes, thereby improving the efficiency of ice forming. Furthermore, when the ice making machine is operating normally, the ice mold 9 continuously provides a freezing point for the water, accelerating the ice making process and effectively improving ice making efficiency.

[0032] Preferably, the upper end of the water inlet pipe 4 is located at the right end of the ice box 1, and the upper end of the water return pipe 3 is located at the left end of the ice box 1. Circulating water enters the right end of the ice box 1, flows through the multiple ice molds 9, and is then pumped out through the water return pipe 3. This entire process effectively increases the agitation range of the circulating water agitation mechanism, allowing the water in the entire ice box 1 to be agitated by the circulating water, further improving the transparency and uniformity of the produced ice cubes.

[0033] In one embodiment of the present invention, a three-way valve 6 is connected to the lower end of the water inlet pipe 4 and the lower end of the return pipe 3. The three-way valve 6 is connected to the water tank 8 through the water supply pipe 7. The water tank 8 is used to hold water. Preferably, a water pump 5 is used as the power source of the circulating water stirring mechanism. The discharge port of the water pump 5 is connected to the water inlet pipe 4. The water inlet of the water pump 5 is connected to the three-way valve 6 through the pumping pipe. When the ice making machine is in the water supply state, it is necessary to supply water to the ice box 1. The water supply water circuit is opened through the three-way valve 6 and the circulating water circuit is closed, that is, the water supply pipe 7 is opened and the return pipe 3 is closed. The water pump 5 sucks the water in the water tank 8 through the water supply pipe 7 and transports it to the ice box 1 through the water inlet pipe 4. When the water volume in the ice box 1 reaches a certain level and the ice making machine is in ice making working state, the circulating water circuit is opened through the three-way valve 6 and the water supply circuit is closed, that is, the return water pipe 3 is opened and the water supply pipe 7 is closed. The water pump 5 sucks the water in the ice box 1 through the suction pipe and re-delivers it to the ice box 1 through the water inlet pipe 4, completing the water circulation in the ice box 1.

[0034] It should be noted that the water inlet pipe 4 and the water return pipe 3 have a certain heat preservation function. When water flows in the water inlet pipe 4 and the water return pipe 3, the temperature will not change significantly, thereby ensuring the efficiency of ice preparation.

[0035] In one embodiment of the present invention, the upper end of the water inlet pipe 4 is L-shaped, and the angle between the upper end of the water inlet pipe 4 and the horizontal plane is 30-90 degrees, preferably, the angle between the upper end of the water inlet pipe 4 and the horizontal plane is 45 degrees. In this case, when water flows axially in the ice box 1, the water ejected from the water inlet pipe 4 can drive the water in the ice box 1 to move in the circumferential direction of the ice box 1, thereby increasing the flow rate and the range of water movement in the ice box 1. On the other hand, the upper end of the water return pipe 3 is L-shaped, and the angle between the upper end of the water return pipe 3 and the horizontal plane is 30-90 degrees, preferably, the angle between the upper end of the water return pipe 3 and the horizontal plane is 45 degrees. The coordinated arrangement of the water return pipe 3 and the water inlet pipe 4 further increases the flow rate and the range of water movement in the ice box 1, thereby improving the transparency and uniformity of the ice cubes produced.

[0036] The evaporator 2 is U-shaped as a whole, and two rows of ice molds 9 are arranged in an array below the outer wall of the evaporator 2, and the water inlet and the water outlet of the evaporator 2 are both located at the same end of the evaporator 2, which is convenient for the arrangement of equipment connected to the evaporator 2.

[0037] In one embodiment of the present invention, a drain port 101 is provided on the upper end surface of the ice box 1. The drain port 101 is located in the middle portion of the ice box 1. When the water in the ice box 1 reaches a certain height, it will preferentially overflow from the drain port 101. This will prevent the water from overflowing from multiple locations in the ice box 1. Furthermore, the size of the ice cubes can be precisely limited, thereby ensuring that the specifications of the ice cubes formed in the ice box 1 remain as consistent as possible.

[0038] In one embodiment of the present invention, drive shafts are coaxially disposed at both ends of the ice box 1. The drive shafts are connected to the output ends of a drive motor 12. Drive motor 12 is preferably a three-phase asynchronous motor. Initially, the top surface of the ice box 1 is aligned with the horizontal plane. The output ends of the drive motor 12 drive the drive shafts to rotate forward by at least 60°, which in turn drives the ice box 1 to rotate synchronously, discharging the ice cubes formed within the ice box 1. A water tank 8 is disposed directly below the ice box 1. The water tank 8 receives the ice cubes discharged from the ice box 1 and simultaneously receives water discharged from a drain port 101. A partition 13 is provided within the water tank 8 to filter water, retaining the ice cubes above the water tank 8. Water then flows through the partition 13 into the bottom of the water tank 8 for centralized collection. The output ends of the drive motor 12 drive the drive shafts to rotate in the opposite direction, which in turn drives the ice box 1 to rotate synchronously, until the top surface of the ice box 1 is aligned with the horizontal plane, at which point the next ice-making process begins.

[0039] In addition, the water inlet of the evaporator 2 and the water outlet of the evaporator 2 are both arranged on the right side of the ice box 1. At the same time, the water inlet pipe 4 and the return pipe 3 are both arranged on the right side of the ice box 1 to ensure that the output end of the drive motor 12 can smoothly drive the ice box 1 to rotate forward through the drive shaft without blocking the movement of the ice box 1.

[0040] When the utility model is used, the water supply pipe 7 is opened and the return water pipe 3 is closed. The water pump 5 pumps water from the water tank 8 through the water supply pipe 7 and transports it to the ice box 1 through the water inlet pipe 4 until the water volume in the ice box 1 reaches a certain level. The return water pipe 3 is opened and the water supply pipe 7 is closed. The water pump 5 pumps water from the ice box 1 through the return water pipe 3 and transports it to the ice box 1 through the water inlet pipe 4. The water in the ice box 1 circulates, the evaporator 2 works to convert the refrigerant from liquid to gaseous state to absorb heat for refrigeration, the evaporator 2 transfers the temperature to the ice box 1, provides a freezing point to the water through the ice mold 9, accelerates the rapid solidification of the water into ice cubes, and the circulating water in the ice box 1 gradually freezes and forms.

[0041] In summary, while the circulating water stirring mechanism provides circulating water to the ice box 1, it can also stir the water in the ice box 1 to a certain extent, so that the water in the ice box 1 is always in a flowing state. The water in the ice box 1 flows at a faster speed and over a wider range. When the temperature of the evaporator 2 is low, the air in the water is still difficult to be frozen into the ice, which effectively reduces the bubbles in the ice cubes and improves the transparency and uniformity of the ice cubes.

[0042] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
