Description

Technical Field

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

[0002] The evaporator is one of the most core components of the ice maker. The ice maker generates ice by cooling the refrigerant in the refrigeration system through the evaporator. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, and uses water as a carrier to absorb the heat of the air and exchange it with the water medium to achieve the refrigeration effect.

[0003] The grid, condenser tube and bottom plate of the traditional ice machine evaporator are all made of copper, so as to achieve the heat conduction effect of the condenser tube transferring heat to the grid through the bottom plate, that is, the condenser tube cools the water in the grid on the front side of the bottom plate through the bottom plate.

[0004] In the prior art, a Chinese patent for an ice-making evaporator (publication number CN210292461U) is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: the evaporation tube is directly in contact with the corresponding side of the ice-making grid or used as the side of the ice-making grid, so that heat exchange is achieved through multiple sides of the ice-making grid, and refrigeration and freezing are performed. The ice-making speed is fast, and ice is conducted from the side of the ice-making grid to its bottom surface. The transmission distance is shorter, the evaporation area is greatly increased, the ice-making function of the ice-making grid is realized, the refrigeration effect is better, the structure is simplified, the installation and production are convenient, and the working efficiency of the evaporator is improved. However, since there are multiple grids in the ice-making grid, the grid needs to be filled with the help of an auxiliary control system, and if the control is not good during the control process, water leakage will occur, and then the ice cubes already made in the ice-making equipment will stick together, thereby affecting the ice-making effect.

[0038] like Figure 1 and Figure 5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the water intake assembly includes a piston plate 10, which is slidably connected between the inner walls of the energy storage cylinder 5, and a spring 11 is fixedly connected between one side of the piston plate 10 and one side of the inner wall of the energy storage cylinder 5, a connecting hole 12 is opened at one end of the energy storage cylinder 5, a through hole communicating with the interior of the energy storage cylinder 5 is opened on the sliding cover 4, an electric valve 19 is arranged inside the through hole, a diversion chamber 14 is opened on one side of the sliding cover 4, and a limiting plate is arranged on the inner wall of the energy storage cylinder 5.

[0042] In this embodiment, the sliding movement between the sliding cover 4 and the grid plate 1 can be limited so that the two can only slide within a limited distance in a straight line direction.

[0043] like Figure 1 and Figure 5 As shown, preferably, a pressure relief pipe 13 is provided on one side of the sliding cover 4 close to the energy storage cylinder 5 , the pressure relief pipe 13 is communicated with the inside of the diverter chamber 14 , and a one-way valve is provided inside the pressure relief pipe 13 .

[0044] In this embodiment, when water is filled into the sliding cover 4 through the energy storage cylinder 5 , the sliding cover 4 will release the exhaust pressure to the outside through the pressure relief pipe 13 .

[0046] In this embodiment, when the first adapter hole 17 is exactly opposite to the second adapter hole 20 , the water source located outside enters the energy storage cylinder 5 from the water supply pipe 7 through the two adapter holes (the first adapter hole 17 and the second adapter hole 20 ) and the hollow shaft 6 .

[0047] Example 4

[0048] like Figure 5 and Figure 7 As shown, based on Example 3, the utility model provides a technical solution: preferably, a sleeve 18 is fixedly connected to the outer side of the water supply pipe 7, and the inner wall of the sleeve 18 and the outer side of the second adapter 16 are both provided with rough surfaces, and the inner wall of the sleeve 18 is in contact with the outer side of the second adapter 16.

[0049] In this embodiment, during the flipping process, the first adapter 15 rotates relative to the second adapter 16, and at the same time, the rough surfaces between the sleeve 18 and the second adapter 16 rub against each other, thereby generating vibration, making it easier for the ice cubes to fall off.

[0050] like Figure 5 and Figure 6 As shown, preferably, a protrusion is provided inside each grid of the grid plate 1 on one side of the refrigeration plate 2, and the refrigeration pipe inside the refrigeration plate 2 is communicated with the inside of the protrusion.

[0051] In this embodiment, the contact area between the refrigeration plate 2 and water can be increased, and the distance for heat exchange with water can be reduced, thereby improving the refrigeration effect.

[0052] The working principle of the ice making evaporator is described in detail below.

[0053] like Figure 1 - Figure 7 As shown, when making ice, the grid plate 1 is located directly above the refrigeration plate 2. By opening the electric valve 19, the water stored in the energy storage cylinder 5 flows from the through hole to the diversion chamber 14 and diffuses into each grid. When the top of the piston plate 10 in the energy storage cylinder 5 hits the limit plate, the spatial volume of the chamber below the piston plate 10 is less than the sum of the volumes of all grids minus the protrusions. Therefore, under the rebound of the spring 11, the piston plate 10 is pushed downward to squeeze the water into each grid; then the refrigeration plate 2 is controlled to work to refrigerate, so that the water in the grid plate 1 condenses into ice, and a small amount of expansion occurs during the process, so that each grid is filled; then the external motor is controlled to work, and the pulley and the hollow shaft 6 are driven to rotate through the belt drive, so that the sliding cover 4 is flipped, and the electric valve 19 is controlled to close. During the flipping process, the first adapter 15 rotates relative to the second adapter 16, and at the same time, the rough surface between the sleeve 18 and the second adapter 16 rubs, thereby generating vibration, so that the ice cubes fall off, and flip to a certain angle at the same time. When the refrigeration plate 2 is positioned above the grid plate, the ice cubes completely fall off, and the first adapter hole 17 is aligned with the second adapter hole 20 (the two adapter holes are only partially aligned during the process, and water filling begins, and the two holes can be fully filled when they are offset again). At this time, the water source located outside enters the energy storage cylinder 5 from the water supply pipe 7 through the two adapter holes (the first adapter hole 17 and the second adapter hole 20) and the hollow shaft 6, and squeezes the piston plate 10, so that the spring 11 is squeezed until the piston plate 10 contacts the limit plate. At this time, the water storage reaches the limit, and the motor continues to work, driving the slide cover 4 to continue to flip, until it is tilted to the range of 180 degrees to 360 degrees, the grid plate 1 begins to reset, and the friction between the sleeve 18 and the second adapter 16 will generate vibration to assist in the reset; after the complete reset, the slide cover 4 completely covers the grid plate 1, and the electric valve 19 is controlled to open to supply water to the grid plate 1 through the energy storage cylinder 5, and the operation cycle is entered.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
