Description

Technical Field

[0001] This utility model relates to the field of ice-making equipment, and in particular to an ice maker. Background Technology

[0002] An ice maker is a refrigeration machine that uses refrigerant to absorb heat in an evaporator, causing water to freeze into ice. To produce highly transparent ice cubes, the water in the ice-making container needs to be kept flowing during the ice-making process. A circulating water system is an effective way to achieve this. Currently, most ice makers have water inlet and outlet on the side of the ice maker, meaning the inlet and outlet connectors of the return water pipe are located on the side of the ice maker. This occupies some lateral space and limits the ultra-thin design of the equipment. Utility Model Content

[0010] In one embodiment, the water circulation system further includes a water level sensor and a controller. The water level sensor is connected to the ice maker, and the controller is electrically connected to the water level sensor and the second pump body. The controller controls the second pump body to shut down based on the signal fed back by the water level sensor.

[0011] In one embodiment, the water circulation system further includes a water conveying component disposed between the cover plate and the ice maker, for connecting the first water conveying channel and the chamber of the ice maker, and connecting the chamber of the ice maker and the second water conveying channel.

[0012] In one embodiment, the water conveying component includes a first guide tube, a second guide tube, and a third guide tube. The first guide tube is closed at one end and open at the other end, with the opening of the first guide tube communicating with the first water conveying channel. The second guide tube is closed at one end and open at the other end, with the opening of the second guide tube communicating with the second water conveying channel. The third guide tube is horizontally disposed within the cavity of the ice maker, and both ends of the third guide tube are respectively connected to the first guide tube and the second guide tube. A water passage hole is formed in the wall of the third guide tube.

[0013] In one embodiment, the third guide tube has a first end facing the first guide tube and a second end facing the second guide tube. The water passage includes a first water passage and a second water passage. The first water passage is disposed on the tube wall of the first end, and the second water passage is disposed on the tube wall of the second end. The first end is a water inlet, and the second end is a water outlet. The flow cross-section of the second water passage is larger than the flow cross-section of the first water passage.

[0014] This invention relates to an ice maker with a cover plate on the top of the ice maker body. The cover plate has a first water inlet channel and a second water inlet channel communicating with the ice-making chamber. A water circulation system is used to dynamically circulate the water in the ice-making chamber during the ice-making process, resulting in ice with high transparency. Specifically, the water circulation system includes a return water pipe and a first pump body connected to the return water pipe. One end of the return water pipe is connected to the first water inlet channel, and the other end is connected to the second water inlet channel. When the first pump body is activated, water in the ice-making chamber flows into the return water pipe through one of the water inlet channels under the action of the first pump body, and then flows back to the ice-making chamber from the return water pipe through the other water inlet channel, thus achieving circulation. Clearly, in this invention, the water circulation system no longer enters from the side of the ice maker body, but instead connects from top to bottom to the first and second water inlet channels on the cover plate, avoiding the occupation of lateral space by the pipes and facilitating the ultra-thin design of the ice maker.

[0022] An ice maker is a refrigeration machine that uses refrigerant to absorb heat in an evaporator, causing water to freeze into ice. To produce highly transparent ice cubes, the water in the ice-making container needs to be kept flowing during the ice-making process. A circulating water system is an effective way to achieve this. Currently, most ice makers have water inlet and outlet on the side of the ice maker, meaning the inlet and outlet connectors of the return water pipe are located on the side of the ice maker. This occupies some lateral space and limits the ultra-thin design of the equipment.

[0023] To address this issue and promote the ultra-thin design of equipment, this utility model proposes an ice maker.

[0024] like Figures 1 to 4 As shown, the ice maker provided in this embodiment of the present invention includes an ice-making component and a water circulation system. The ice-making component includes a refrigerator body 11, a cover plate 12 covering the top of the refrigerator body 11, and an ice-making box 13 disposed inside the refrigerator body 11. The cover plate 12 is provided with a first water supply channel 121 and a second water supply channel 122 communicating with the cavity of the ice-making box 13. The water circulation system includes a return water pipe 21 and a first pump body 22 connected to the return water pipe 21. The two ends of the return water pipe 21 are respectively connected to the first water supply channel 121 and the second water supply channel 122.

[0025] In this embodiment of the ice maker, a cover plate 12 is provided on the top of the ice maker body 11. The cover plate 12 has a first water supply channel 121 and a second water supply channel 122 that communicate with the cavity of the ice maker 13. A water circulation system is used to dynamically circulate the water in the ice maker 13 during the ice-making process, so that the resulting ice cubes have high transparency. Specifically, the water circulation system includes a return water pipe 21 and a first pump body 22 connected to the return water pipe 21. One end of the return water pipe 21 is connected to the first water supply channel 121, and the other end is connected to the second water supply channel 122. When the first pump body 22 is activated, the water in the ice maker 13 flows into the return water pipe 21 through one of the water supply channels under the action of the first pump body 22, and then flows back to the ice maker 13 from the return water pipe 21 through the other water supply channel, thereby achieving circulation. Obviously, in the ice maker of this utility model, the water circulation system is no longer connected from the side of the ice maker body 11, but is connected from top to bottom to the first water supply channel 121 and the second water supply channel 122 on the cover plate 12. This can avoid the pipes occupying the horizontal space and is conducive to the ultra-thin design of the ice maker.

[0026] The refrigerator body 11 is a box structure with an open top, and the cover 12 can be detachably installed on the top of the refrigerator body 11. For example, the cover 12 and the refrigerator body 11 can be connected by snap-fit ​​or screws. The cover 12 and the refrigerator body 11 are detachably connected, which makes it convenient for users or maintenance personnel to open the cover 12 to inspect or clean the internal components of the refrigerator body 11.

[0027] The ice-making assembly also includes an evaporator 14, which includes evaporation tubes 141 and multiple ice-making columns 142 spaced apart from the evaporation tubes 141. Each ice-making column 142 extends at least partially into the cavity of the ice-making box 13, thus contacting the water inside the ice-making box 13. The refrigerant flowing within the evaporator 14 transfers cooling energy to the ice-making columns 142, and then through the ice-making columns 142 to the water inside the ice-making box 13, causing the water in the ice-making box 13 to condense into ice. Because the ice-making columns 142 have a columnar structure, the ice blocks formed on the multiple ice-making columns 142 can be bullet-shaped. After the ice blocks have solidified, a high-temperature fluid, which can be a gas or a liquid, is introduced into the evaporator 14. The heat of the high-temperature fluid is transferred to the ice-making columns 142, melting the contact surface between the ice blocks and the ice-making columns 142, causing the ice blocks to fall off for easy removal later.

[0028] In this embodiment of the ice maker, the top surface of the cover plate 12 may be provided with a receiving groove 124. The first water supply channel 121 and the second water supply channel 122 are respectively provided on the bottom wall of the receiving groove 124 and extend to the bottom surface of the cover plate 12. The return water pipe 21 is at least partially disposed in the receiving groove 124. By recessing the receiving groove 124 on the top surface of the cover plate 12 and embedding the return water pipe 21 in the receiving groove 124, the return water pipe 21 can be prevented from protruding from the top surface of the cover plate 12 and occupying vertical space. This ensures that the vertical dimension of the entire machine will not increase the vertical space occupied due to the return water pipe 21 being connected from top to bottom, thus minimizing the horizontal and vertical space occupied by the equipment.

[0029] In practical applications, the return water pipe 21 can be completely housed in the receiving tank 124. At this time, the length of the receiving tank 124 is at least equal to the length of the return water pipe 21. The first water supply channel 121 is set on the bottom wall of one end of the receiving tank 124 and extends to the bottom surface of the cover plate 12. The second water supply channel 122 is set on the bottom wall of the other end of the receiving tank 124 and extends to the bottom surface of the cover plate 12. One end of the return water pipe 21 is connected to the first water supply channel 121, and the other end of the return water pipe 21 is connected to the second water supply channel 122.

[0030] Alternatively, the return water pipe 21 may be partially housed within the receiving tank 124 and partially located outside the receiving tank 124. Specifically, the return water pipe 21 has an inlet pipe 211 and an outlet pipe 212, as shown in Figure 21. Figure 2 and Figure 3The receiving tank 124 includes a first receiving tank 1241 and a second receiving tank 1242. Both the first and second receiving tanks are strip-shaped, with one end extending to one edge of the cover plate 12. A first water supply channel 121 is located on the bottom wall of the first receiving tank 1241 and extends to the bottom surface of the cover plate 12. A second water supply channel 122 is located on the bottom wall of the second receiving tank 1242 and extends to the bottom surface of the cover plate 12. An inlet pipe 211 is housed in the first receiving tank 1241 and communicates with the first water supply channel 121. An outlet pipe 212 is housed in the second receiving tank 1242 and communicates with the second water supply channel 122. In this case, the return pipe 21 is longer, which extends the water circulation path. With the extended path, the water's residence time in the return pipe 21 increases, giving air bubbles in the water a greater chance to precipitate, thereby further improving the transparency of the ice.

[0031] Reference Figure 1 In this embodiment of the ice maker, the water circulation system further includes a water storage tank 23. A water supply pipe 24 is provided between the water storage tank 23 and the ice maker 13 to connect the chamber of the water storage tank 23 and the chamber of the ice maker 13. The water supply pipe 24 is connected to a second pump body 25.

[0032] Understandably, the water storage tank 23 is used to store water and supply water to the ice maker 13. The water stored in the water storage tank 23 flows into the ice maker 13 through the water pipe 24 under the action of the second pump body 25. Once the water level in the ice maker 13 reaches the required level, the second pump body 25 shuts off, the evaporator 14 starts working to cool, the first pump body 22 starts, and the water in the ice maker 13 begins to circulate. The water storage tank 23 can be connected to an external water source, such as by connecting an inlet pipe. The inlet end of the inlet pipe connects to an external water source, such as an external water tank or a municipal water tap. The outlet end of the inlet pipe connects to the chamber of the water storage tank 23. The inlet pipe is equipped with a valve to control the on / off state of the inlet pipe. Alternatively, the user can remove the water storage tank 23, fill it completely, and then reinstall it into the ice maker.

[0033] The water storage tank 23 can be located below the refrigerator body 11, and the water storage tank 23 is within the coverage area of ​​the refrigerator body 11. That is, the refrigerator body 11 and the water storage tank 23 are arranged vertically, and the outer contour of the water storage tank 23 does not exceed the outer contour of the refrigerator body 11, so that the overall structure of the water storage tank 23 and the refrigerator body 11 is relatively compact, which is conducive to the ultra-thin design of the equipment.

[0034] The refrigerator body 11 is provided with a water collection cavity 111, which is located below the ice maker 13. The refrigerator body 11 is also provided with an ice storage basket 15, which is located between the ice maker 13 and the water collection cavity 111. The bottom of the ice storage basket 15 is provided with a water filter hole 151. A water delivery channel 112 is provided between the refrigerator body 11 and the water storage tank 23 to connect the chambers of the water collection cavity 111 and the water storage tank 23.

[0035] The embodiment of the ice maker also includes an ice-removing structure, which is connected to the ice-making container 13 for tilting the container and allowing the ice to fall into the ice storage basket 15 below. If the ice is not removed in time, it will melt. The melted ice water will fall into the water storage tank 23 through the filter holes 151 and the water delivery channel 112 of the ice storage basket 15 for collection. When the ice-making container 13 needs to make ice again, the ice water collected in the water storage tank 23 will be sent back to the container 13 through the water delivery pipe 24 for reuse, avoiding waste of melted ice water. Moreover, the temperature of this ice water is relatively low, and using ice water to make ice can speed up the freezing time of the ice and improve the ice-making efficiency.

[0036] Reference Figure 2 and Figure 3 The cover plate 12 is also provided with a third water supply channel 123 that communicates with the chamber of the ice box 13, and the water outlet of the water pipe 24 is connected to the third water supply channel 123. The water pipe 24 is connected to the third water supply channel 123 on the cover plate 12 from top to bottom, which can avoid the water pipe 24 occupying the horizontal space and is conducive to the ultra-thin design of the ice maker.

[0037] The top surface of the cover plate 12 may also be provided with a receiving groove 125, and the outlet end of the water supply pipe 24 is embedded in the receiving groove 125. The third water supply channel 123 is provided on the bottom wall of the receiving groove 125 and extends to the bottom surface of the cover plate 12. The top surface of the cover plate 12 is recessed with a receiving groove 125 for receiving the water supply pipe 24, which can prevent the outlet end of the water supply pipe 24 from protruding from the top surface of the cover plate 12 and occupying the space, thus ensuring that the lateral space and space occupied by the equipment are minimized.

[0038] In practical applications, the second pump body 25 can be manually turned on and off. This requires the user to wait in front of the ice maker for a period of time until the ice box 13 is full of water before turning off the second pump body 25 in time to prevent water from overflowing from the ice box 13 and spreading to the internal electronic components, causing short circuits.

[0039] To avoid the lag of human operation, the water circulation system may also include a water level sensor and a controller. The water level sensor is connected to the ice box 13, and the controller is electrically connected to the water level sensor and the second pump body 25. The controller controls the second pump body 25 to shut down based on the signal fed back by the water level sensor.

[0040] Specifically, the water level sensor can be, but is not limited to, an infrared sensor, a distance sensor, and a gravity sensor. The water level sensor is connected to the ice-making container 13 and is used to detect the water level inside the ice-making container 13. When the water level sensor detects that the water level in the ice-making container 13 has reached the set upper limit, it immediately triggers the controller to shut down the second pump body 25, stopping the filling of water into the ice-making container 13 and preventing water from overflowing. In this embodiment, by detecting the water level inside the ice-making container 13 with a water level sensor, the controller can control the second pump body 25 to shut down based on the signal fed back by the water level sensor. This ensures that the water level is accurately stopped at a safe level each time water is added, resulting in high machine stability and avoiding the tediousness and lag of manual operation.

[0041] In some embodiments of the ice maker of this utility model, the water circulation system further includes a water conveying component 26. The water conveying component 26 is disposed between the cover plate 12 and the ice container 13, serving to connect the first water conveying channel 121 and the chamber of the ice container 13, as well as to connect the chamber of the ice container 13 and the second water conveying channel 122. Thus, when the first pump body 22 is activated, water in the ice container 13 flows into the water conveying component 26 under the action of the first pump body 22, and then flows into the return water pipe 21 through the first water conveying channel 121. The water in the return water pipe 21 then flows back into the chamber of the ice container 13 through the second water conveying channel 122 and the water conveying component 26, thereby circulating. The arrangement of the water conveying component 26 ensures that the water inlet and outlet of the ice container 13 have a clear flow path.

[0042] Reference Figures 5 to 8 The water supply component 26 may include a first guide tube 261, a second guide tube 262, and a third guide tube 263. The first guide tube 261 is closed at one end and open at the other end, and the opening of the first guide tube 261 is connected to the first water supply channel 121. The second guide tube 262 is closed at one end and open at the other end, and the opening of the second guide tube 262 is connected to the second water supply channel 122. The third guide tube 263 is horizontally disposed in the cavity of the ice box 13, and both ends of the third guide tube 263 are connected to the first guide tube 261 and the second guide tube 262, respectively. A water passage hole 2631 is formed in the wall of the third guide tube 263.

[0043] Specifically, the water supply component 26 is fixedly connected to the top of the ice maker 13. The water supply component 26 includes a first guide tube 261 and a second guide tube 262 arranged parallel and vertically. The lower ends of the first guide tube 261 and the second guide tube 262 extend into the cavity of the ice maker 13. A third guide tube 263 is arranged horizontally within the cavity of the ice maker 13. One end of the third guide tube 263 is connected to the first guide tube 261, and the other end is connected to the second guide tube 262. The upper ends of the first guide tube 261 and the second guide tube 262 are connected to the first water supply channel 121 and the second water supply channel 122, respectively. The lower ends of both the first guide tube 261 and the second guide tube 262 are closed. Therefore, when the first pump body 22 starts, assuming that the end where the first guide pipe 261 is located is the water inlet and the end where the second guide pipe 262 is located is the water outlet, the flow path of the circulating water circuit is: the chamber of the ice box 13 - water passage hole 2631 - third guide pipe 263 - second guide pipe 262 - second water supply channel 122 - return water pipe 21 - first water supply channel 121 - first guide pipe 261 - third guide pipe 263 - water passage hole 2631 - chamber of the ice box 13.

[0044] Furthermore, the third guide tube 263 has a first end 2633 facing the first guide tube 261 and a second end 2634 facing the second guide tube 262. The water passage 2631 includes a first water passage 2631a and a second water passage 2631b. The first water passage 2631a is disposed on the tube wall of the first end 2633, and the second water passage 2631b is disposed on the tube wall of the second end 2634. Thus, water in the ice maker 13 will enter the third guide tube 263 through the second water passage 2631b, and water flowing back from the third guide tube 263 will flow back to the chamber of the ice maker 13 through the first water passage 2631a. Specifically, the flow path of the circulating water circuit is as follows: ice box 13 chamber - second water passage 2631b - third guide pipe 263 - second guide pipe 262 - second water supply channel 122 - return water pipe 21 - first water supply channel 121 - first guide pipe 261 - third guide pipe 263 - first water passage 2631 - ice box 13 chamber.

[0045] The first water passage hole 2631a and the second water passage hole 2631b can be circular holes, and at least two of each type are provided. The number of second water passage holes 2631b can be the same as or different from the number of first water passage holes 2631a; no restriction is placed here. At least two first water passage holes 2631a are spaced apart along the length of the third guide pipe 263, and at least two second water passage holes 2631b are also spaced apart along the length of the third guide pipe 263. Providing at least two of each type avoids the problem of slow efficiency associated with single-point water inlet and outlet.

[0046] Alternatively, the first water passage 2631a and the second water passage 2631b can be strip-shaped holes. In this case, one of each type of water passage 2631a and 2631b is provided, and both extend along the length of the third guide tube 263. Designing the first water passage 2631a and the second water passage 2631b as strip-shaped holes allows them to have larger flow cross-sections, and also avoids the problem of slow efficiency with single-point water inlet and single-point water outlet.

[0047] When the first end 2633 is the inlet and the second end 2634 is the outlet, the flow cross-section of the second water passage 2631b can be larger than the flow cross-section of the first water passage 2631a. For example, in... Figure 5 In the illustrated embodiment, the diameter of the water passage 2631 gradually increases from the first end 2633 to the second end 2634. According to Bernoulli's principle, the smaller diameter of the first end 2633 allows for a higher inlet pressure, enabling water to be injected into the ice-making container 13 with higher dynamic pressure, causing water flow within the ice-making container 13 and resulting in ice with higher transparency. The larger diameter of the second end 2634 allows for a lower outlet pressure, allowing excess water to drain smoothly and naturally. When the first end 2633 is the outlet and the second end 2634 is the inlet, the flow cross-section of the first water passage 2631a is larger than that of the second water passage 2631b.

[0048] The first water passage 2631a and the second water passage 2631b can be arranged in the same direction or in opposite directions. Arranging the first water passage 2631a and the second water passage 2631b in opposite directions separates the water inlet and outlet areas, preventing interference between the inlet and outlet water flows and the formation of eddies. Preferably, the second water passage 2631b can be arranged facing the ice-making column 142, and the first water passage 2631a can be arranged in opposite directions to the second water passage 2631b, that is, the first water passage 2631a is oriented away from the ice-making column 142. This arrangement prevents the water ejected from the first water passage 2631a from carrying away the cold energy of the ice-making column 142, eroding the already formed ice on the ice-making column 142, and preventing the already formed ice from deforming.

[0049] Reference Figure 8 In at least one embodiment, a partition 2632 may be provided inside the third guide tube 263. The partition 2632 is located in the middle of the third guide tube 263, thereby dividing the third guide tube 263 into a first end 2633 facing the first guide tube 261 and a second end 2634 facing the second guide tube 262. The partition 2632 can effectively isolate the chamber of the first end 2633 and the chamber of the second end 2634 of the third guide tube 263, avoiding mutual interference between the inlet flow path and the outlet flow path.

[0050] Reference Figure 5 The water conveying component 26 also includes reinforcing ribs 264, which are disposed between the first guide pipe 261 and the second guide pipe 262, with both ends of the reinforcing ribs 264 connected to the walls of the first guide pipe 261 and the second guide pipe 262, respectively. Specifically, the reinforcing ribs 264 are integrally formed with the first guide pipe 261 and the second guide pipe 262 through injection molding. The reinforcing ribs 264 can be block-shaped ribs or multiple ribs spaced apart. The inclusion of reinforcing ribs 264 can improve the structural strength of the water conveying component 26 and enhance its overall resistance to deformation and impact.

[0051] The water supply component 26 may also include a first mounting base 265 and a second mounting base 266 for fixed connection with the cover plate 12. The first mounting base 265 protrudes from the periphery of the first guide tube 261, and the second mounting base 266 protrudes from the periphery of the second guide tube 262. The first mounting base 265 and the second mounting base 266 are at the same height.

[0052] Specifically, the first mounting base 265 and the second mounting base 266 can be fixedly connected to the cover plate 12 by screws or snap-fit ​​structure. The first mounting base 265 protrudes from the periphery of the first guide tube 261, and the second mounting base 266 protrudes from the periphery of the second guide tube 262. The first guide tube 261 has a portion that protrudes upward from the first mounting base 265, and the second guide tube 262 has a portion that protrudes upward from the second mounting base 266. The protruding portion of the first guide tube 261 is inserted into the first water supply channel 121 on the cover plate 12 to communicate with the first water supply channel 121, and the protruding portion of the second guide tube 262 is inserted into the second water supply channel 122 on the cover plate 12 to communicate with the second water supply channel 122. The first guide tube 261 and the second guide tube 262 have the same length, and the first mounting base 265 and the second mounting base 266 are at the same height, so that the first guide tube 261 and the second guide tube 262 can extend into the cover plate 12 to the same depth, and the first guide tube 261 and the second guide tube 262 can be hung at the same height, so that the third guide tube 263 can be installed horizontally.
