Description

Technical Field

[0001] The utility model relates to the technical field of ice making, and particularly to a refrigerator. Background Art

[0002] Ice-making products on the market are mainly divided into two categories: manual ice-making and automatic ice-making. Both of these two categories adopt the method of static water ice-making. The ice produced by the method of static water ice-making is in a non-transparent state, and there are bubbles inside the ice. In this way, when cooling drinks, it will accelerate the melting speed of the ice body, affecting the taste of the drinks, and the non-transparent ice body will also affect the user experience. When the existing ice-making equipment needs to take out the ice after the ice-making is completed in the ice-making cavity, it is necessary to first remove the water in the large-area drainage area, which is inconvenient to operate, and it is impossible to take out and de-ice the ice in time, making it difficult to meet the user's needs. Moreover, in order to prevent the drainage channel from freezing during the ice-making process, it is also necessary to set heating components near the drainage area, which is relatively cumbersome and there are many devices. At the same time, the spherical ice produced is difficult to take because of its poor freezing with the surrounding and the bottom, and the device composition is complex and inconvenient to use.

[0052] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, the ice maker provided by the embodiment of the present utility model includes a housing 500, a water supply device 200, and an ice mold 100. The housing 500 has an open opening 560 facing horizontally. The water supply device 200 includes a water tank 210 and a water inlet pipe 230. One end of the water inlet pipe 230 penetrates through the housing 500, and the other end of the water inlet pipe 230 is communicated with the water tank 210. An ice making cavity 110 is provided inside the ice mold 100. The ice mold 100 is provided with a water injection part 130, and the water injection part 130 is communicated with the ice making cavity 110. The ice mold 100 is adapted to enter and exit the housing 500 through the open opening 560. When entering the housing 500, the water injection part 130 is communicated with one end of the water inlet pipe 230 located inside the housing 500. When leaving the housing 500, the water injection part 130 is separated from one end of the water inlet pipe 230 located inside the housing 500.

[0053] In the ice maker of the embodiment of the present utility model, the ice mold 100 is arranged inside the housing 500, and the housing 500 is provided with an open opening 560 facing the horizontal direction. The ice mold 100 can be put into the housing 500 or taken out from the inside of the housing 500 through the open opening 560, that is, the ice mold 100 can be horizontally pulled out of the housing 500 through the open opening 560, and can also be horizontally pushed into the housing 500 through the open opening 560, forming a pull-out type ice mold 100. The water supply device 200 is composed of a water tank 210 and a water inlet pipe 230. The water tank 210 is relatively independently arranged with the housing 500. One end of the water inlet pipe 230 passes through the housing 500 and enters the inside of the housing 500, and the other end of the water inlet pipe 230 is communicated with the water tank 210, that is, the housing 500 forms a fixed whole with the water tank 210 through the water inlet pipe 230. The ice mold 100 is provided with an ice making cavity 110 and a water injection part 130 communicated with the ice making cavity 110. When the ice mold 100 is put into the inside of the housing 500, the water injection part 130 is communicated with the end of the water inlet pipe 230. When the ice mold 100 is taken out from the inside of the housing 500, the water injection part 130 is disconnected from the end of the water inlet pipe 230.

[0054] The water tank 210 injects water into the water injection part 130 of the ice mold 100 through the water inlet pipe 230. The water in the water injection part 130 flows into the ice making cavity 110 for ice making. After the ice making is completed, the ice mold 100 is taken out from the open opening 560 of the housing 500. During this period, the water injection part 130 is detached from the water inlet pipe 230, and the position of the water inlet pipe 230 on the housing 500 remains unchanged. The ice mold 100 can be opened for deicing, and then the ice mold 100 is put into the inside of the housing 500 through the open opening 560. During this period, the water injection part 130 is connected to the water inlet pipe 230. Thus, ice making and manual deicing are realized.

[0055] The ice maker of the present utility model relatively fixes the position of the water supply device 200 and the housing 500 through the position of the water inlet pipe 230 and the housing 500. With the open-mouth 560 design of the housing 500 and combined with the connection relationship between the ice mold 100, the housing 500 and the water inlet pipe 230, during the ice-making and ice-taking processes, only the position of the ice mold 100 changes, and it is adapted to the detachable connection between the water injection part 130 and the water inlet pipe 230, which can ensure ice-making water supply and at the same time ensure convenient ice removal operation. The ice maker has a simple composition and an integrated structure, and can realize convenient manual removal of ice cubes without the addition of heating components and fans, etc.

[0056] According to an embodiment of the present utility model, the ice mold 100 is provided with a drainage part 120, and the water supply device 200 further includes a return water pipe 220. One end of the return water pipe 220 penetrates through the housing 500, and the other end of the return water pipe 220 communicates with the water tank 210. When the ice mold 100 enters the housing 500, the drainage part 120 communicates with one end of the return water pipe 220 located inside the housing 500. When the ice mold 100 leaves the housing 500, the drainage part 120 is separated from one end of the return water pipe 220 located inside the housing 500.

[0057] In this embodiment, the water supply device 200 is composed of a water tank 210, a water inlet pipe 230 and a return water pipe 220. The water tank 210 is relatively independently arranged with the housing 500. One end of the return water pipe 220 passes through the housing 500 and enters the inside of the housing 500, and the other end of the return water pipe 220 communicates with the water tank 210, that is, the housing 500 forms a fixed whole with the water tank 210 through the water inlet pipe 230 and the return water pipe 220. The ice mold 100 is provided with an ice-making cavity 110, a water injection part 130 and a drainage part 120 communicated with the ice-making cavity 110. When the ice mold 100 is placed inside the housing 500, the drainage part 120 communicates with the end of the return water pipe 220. When the ice mold 100 is taken out from the inside of the housing 500, the drainage part 120 is disconnected from the end of the drainage pipe.

[0058] The drainage part 120 of the ice mold 100 drains water to the water tank 210 through the return water pipe 220. The water overflowing from the ice-making cavity 110 flows into the drainage pipe through the drainage part 120 and is discharged into the water tank 210. After ice-making is completed, the ice mold 100 is taken out from the open-mouth 560 of the housing 500. During this period, the drainage part 120 is detached from the drainage pipe, and the position of the drainage pipe on the housing 500 remains unchanged. The ice mold 100 can be opened for ice removal, and then the ice mold 100 is put into the inside of the housing 500 from the open-mouth 560. During this period, the drainage part 120 is connected to the return water pipe 220. Thus, ice-making and manual ice removal are realized.

[0059] The ice maker of the present utility model relatively fixes the position of the water supply device 200 and the housing 500 through the position of the water inlet pipe 230 and the housing 500. In combination with the open-mouth 560 design of the housing 500, and further combining the connection relationship between the ice mold 100, the housing 500, the water inlet pipe 230 and the water return pipe 220, during the ice-making and ice-taking processes, only the position of the ice mold 100 changes. Moreover, with the detachable connection between the water injection part 130 and the water inlet pipe 230, and the detachable connection between the water return pipe 220 and the drainage part 120, it can ensure ice-making water supply and drainage while also ensuring convenient ice removal operation. The ice maker has a simple composition and an integrated structure, and can realize the convenient manual removal of ice cubes without the addition of heating components and fans, etc.

[0060] The ice mold 100 has a water injection part 130 and a drainage part 120. The water tank 210 is connected to the water injection part 130 through the water inlet pipe 230 to inject water into the ice-making cavity 110. When the water in the ice-making cavity 110 is full, it overflows from the drainage part 120. During the ice-making process, water is continuously injected into the ice-making cavity 110 and the water in the ice-making cavity 110 continuously overflows. Therefore, there is an ice layer and flowing water in the ice-making cavity 110, which can help and accelerate the precipitation of air bubbles in the water, further ensuring the production of transparent ice. The water tank 210 is connected to the drainage part 120 through the water return pipe 220, so that the water overflowing from the ice-making cavity 110 flows back to the water tank 210, thereby realizing the formation of a circulating water path between the water supply device 200 and the ice mold 100 during the ice-making process.

[0061] According to an embodiment of the present utility model, the water supply device 200 further includes a water supply pipe 250, a water level sensor 260 and a control valve 270. The water supply pipe 250 is connected to the water tank 210; the water level sensor 260 is arranged in the water tank 210; the control valve 270 is arranged on the water supply pipe 250, and the control valve 270 is electrically connected to the water level sensor 260. The control valve 270 is adapted to control the water supply pipe 250 to inject water into the water tank 210 according to the water level in the water tank 210 detected by the water level sensor 260.

[0062] In this embodiment, the water supply device 200 is composed of a water tank 210, a water inlet pipe 230, a water return pipe 220, a water supply pipe 250, a water level sensor 260 and a control valve 270. The water source can supply water to the water tank 210 through the water supply pipe 250. The water level sensor 260 is adapted to detect the real-time water level in the water tank 210. When the water level in the water tank 210 is lower than the first set water level, the water level sensor 260 triggers the control valve 270, and the control valve 270 opens to control the water supply pipe 250 to start injecting water into the water tank 210. When the water level in the water tank 210 is higher than the second set water level, the water level sensor 260 triggers the control valve 270, and the control valve 270 closes to control the water supply pipe 250 to stop injecting water into the water tank 210.

[0063] In this embodiment, the water level sensor 260 can also be a float sensor. Considering the convenience of continuous ice making, a water supply pipe 250 and a control valve 270 are introduced on the water tank 210, and a water level sensor 260 is installed inside the water tank 210. When the water in the water tank 210 gradually decreases during ice making to a certain extent, the control valve 270 is triggered to open for quantitative water supply through the induction of the water level sensor 260, thereby realizing the automatic water supply of this ice maker.

[0064] A water pump 240 is arranged at the bottom of the water tank 210. One end of the water inlet pipe 230 enters the water tank 210 and is communicated with the water pump 240 at the bottom. The water pump 240 provides power for injecting water from the water inlet pipe 230 into the ice mold 100. The water pump 240 works continuously, and a circulating water path is formed between the entire water supply device 200 and the inside of the ice mold 100.

[0065] According to an embodiment of the present invention, the water injection part 130 includes a first water injection channel 131 and a second water injection channel 132. The first water injection channel 131 extends horizontally from the surface of the ice mold 100 into the ice mold 100. One end of the water inlet pipe 230 located inside the housing 500 is detachably connected to the first water injection channel 131; the second water injection channel 132 is communicated with the first water injection channel 131 and extends towards the ice making cavity 110 at a set angle, and the set angle is an angle forming an acute angle with the horizontal direction.

[0066] In this embodiment, the water injection part 130 of the ice mold 100 is mainly composed of a first water injection channel 131 and a second water injection channel 132. The first water injection channel 131 extends from the surface of the ice mold 100 towards the position of the ice making cavity 110 inside the ice mold 100, and the extension direction is horizontal. The second water injection channel 132 is communicated at the extension end of the first water injection channel 131. The second water injection channel 132 extends from the end of the first water injection channel 131 to the ice making cavity 110 and is communicated with the ice making cavity 110, and gradually inclines downward during the extension process, forming an inclined structure with a set angle forming an acute angle with the horizontal direction.

[0067] Through the connection of the first water injection channel 131 and the second water injection channel 132, the water injection part 130 of the ice mold 100 is constructed as a water channel penetrating the ice mold 100. During the ice making process, the water pump 240 continuously pumps the water in the water tank 210 to the first water injection channel 131 of the ice mold 100. After the water flows through the first water injection channel 131, it passes through the second water injection channel 132 with a set angle of inclination and is injected into the ice making cavity 110 at a certain inclined angle. The water flow enters the ice making cavity 110 in an obliquely downward injection form, which can generate water flow rotation in the ice making cavity 110, is beneficial to promoting the precipitation of gas in the water, and thus the ice made has better transparency.

[0068] In this embodiment, the set angle can generally be selected to be about 15°.

[0069] According to an embodiment of the present utility model, the water inlet pipe 230 includes a first pipe interface 231 and a pipe body 232. The housing 500 is provided with a first mounting hole 540. The first end of the first pipe interface 231 is disposed in the first mounting hole 540, and the second end of the first pipe interface 231 is in interference fit and inserted into the first water injection channel 131; one end of the pipe body 232 is inserted into the first end of the first pipe interface 231, and the other end of the pipe body 232 is communicated with the water tank 210.

[0070] In this embodiment, the water inlet pipe 230 of the water supply device 200 is composed of a first pipe interface 231 and a pipe body 232. The housing 500 is provided with a first mounting hole 540. The first pipe interface 231 is designed in two sections, namely the first end and the second end of the first pipe interface 231. The first end is inserted into the first mounting hole 540, and the second end is detachably inserted into the first water injection channel 131. During insertion, interference fit is used to prevent water from leaking at the connection. One end of the pipe body 232 is inserted into the first end, and interference fit can also be used to prevent water from leaking at the connection. The other end of the pipe body 232 extends into the water tank 210 and is communicated with the water pump 240 in the water tank 210. The insertion fit meets the connection requirements of the structural relationship that the ice mold 100 enters and exits the housing 500 horizontally through the open end 560 of the housing 500, facilitating the quick and convenient detachable connection between the water inlet pipe 230 and the ice mold 100, and effectively ensuring no water leakage during ice making and ice taking.

[0071] In this embodiment, the first pipe interface 231 is fixed on the housing 500. After the ice mold 100 enters the housing 500, the end of the first water injection channel 131 approaches the second end until the second end is inserted into the first water injection channel 131. In other embodiments, the second end of the first pipe interface 231 can also be fixed at the end of the first water injection channel 131 of the ice mold 100, and the pipe body 232 is directly fixed in the first mounting hole 540 of the housing 500. After the ice mold 100 enters the housing 500, the first end of the first pipe interface 231 approaches the pipe body 232 until the first end is inserted into the pipe body 232.

[0072] According to an embodiment of the present utility model, the drainage part 120 includes a drainage groove 122, a drainage port 121 and a second pipe interface 123. The drainage groove 122 is arranged at the top edge of the ice mold 100; the drainage port 121 is arranged at the highest position of the ice making cavity 110, and the water in the ice making cavity 110 overflows from the drainage port 121 and converges into the drainage groove 122; the second pipe interface 123 is arranged in the drainage groove 122. The housing 500 is provided with a second mounting hole 550, and the return water pipe 220 is inserted into the second mounting hole 550, and the second pipe interface 123 is in interference fit and inserted into the return water pipe 220.

[0073] In this embodiment, the bottom of the ice mold 100 is the part concentrated on the lower surface of the ice mold 100, and the top of the ice mold 100 is the part concentrated on the upper surface of the ice mold 100. The drainage part 120 at the top of the ice mold 100 is composed of a drain port 121, a drain groove 122, and a second pipe interface 123. The drain port 121 vertically penetrates upward from the highest position of the self-made ice cavity 110 to the top surface of the ice mold 100. The drain groove 122 is a groove formed by the depression of the edge of the top surface of the ice mold 100. The second pipe interface 123 is also of a two-section design, namely the first section and the second section of the second pipe interface 123. That is, the first section is connected to the edge of the ice mold 100, corresponding to the position of the drain groove 122 and extending into the drain groove 122, and the second section extends out of the ice mold 100. A second mounting hole 550 is provided on the housing 500. The return water pipe 220 is inserted into the second mounting hole 550. When inserted, an interference fit is used to prevent water from leaking at the connection. The second section is detachably inserted into the return water pipe 220, and an interference fit can also be used to prevent water from leaking at the connection. The plug-in fit meets the connection requirements of the structural relationship that the ice mold 100 horizontally enters and exits the housing 500 through the open end 560 of the housing 500, facilitating the quick and convenient detachable connection between the return water pipe 220 and the ice mold 100, and effectively ensuring no water leakage during ice making and ice taking.

[0074] Water is injected into the ice making cavity 110 through the water injection part 130. After the water in the ice making cavity 110 accumulates to the highest position of the ice making cavity 110, it will overflow into the drain port 121. The overflowing water flows on the top surface of the ice mold 100 and flows into the sunken drain groove 122, and then flows into the second pipe interface 123 through the drain groove 122. The second end of the second pipe interface 123 is connected to the return water pipe 220 to flow out of the ice mold 100 and back to the water tank 210.

[0075] In this embodiment, the second pipe interface 123 is fixed on the ice mold 100. After the ice mold 100 enters the housing 500, the second section of the second pipe interface 123 approaches the second mounting hole 550 until the second section is inserted into the return water pipe 220 in the second mounting hole 550. In other embodiments, the second section of the second pipe interface 123 can also be fixed to the end of the return water pipe 220 in the second mounting hole 550 of the housing 500. After the ice mold 100 enters the housing 500, the second section of the second pipe interface 123 approaches the ice mold 100 until the first section is inserted into the drain groove 122.

[0076] It can be understood that in this embodiment, the drainage part 120 is in an exposed state on the surface of the ice mold 100. In other embodiments, the drainage part 120 can also be in a non-exposed state provided inside the ice mold 100, that is, the top of the ice mold 100 has a certain thickness, and the drain port 121 and the drain groove 122 are in the form of internal through holes within this top range.

[0077] According to an embodiment of the present utility model, a plurality of ice molds 100 are arranged in a housing 500. The plurality of ice molds 100 are independent of each other. The water inlet pipe 230 is arranged corresponding to each ice mold 100 one by one, and the water return pipe 220 is arranged corresponding to each ice mold 100 one by one. In this embodiment, the plurality of ice molds 100 are independently arranged in the housing 500. The arrangement direction of the plurality of ice molds 100 is the length direction of the housing 500. The length direction of the housing 500 is perpendicular to the direction towards the open end 560. Corresponding first mounting holes 540 and second mounting holes 550 are arranged on the side of the housing 500 opposite to the open end 560 corresponding to each ice mold 100. Accordingly, each ice mold 100 has an independent water inlet pipe 230 and a water return pipe 220 connected thereto. The second mounting hole 550 is located above the first mounting hole 540, that is, the horizontal extension section of the water inlet pipe 230 is located below the water return pipe 220.

[0078] In this embodiment, when ice making is required, the water inlet pipe 230 can independently inject water into its corresponding ice mold 100, and the water return pipe 220 can also independently return water to its corresponding ice mold 100. When ice taking is required after ice making is completed, a single ice mold 100 can be taken out of the housing 500 without affecting the states of other ice molds 100, the water inlet pipe 230 and the water return pipe 220. The water inlet pipe 230 and the water return pipe 220 of the ice mold 100 to be taken out are separated from the ice mold 100, and the ice mold 100 can be taken out of the housing 500 for manual ice taking. Thus, the space occupied by the housing 500 and the water supply device 200 can be saved, the device structure can be simplified, the water injection part 130130 and the drainage part 120120 at the top of the ice mold 100 can be protected from external pollution, and the ice making and ice taking operation actions can be adapted.

[0079] In this embodiment, by arranging a drainage part 120 and a water injection part 130 at the top of each ice mold 100, all the ice molds 100 are arranged in parallel. Water injection into each ice making cavity 110 is carried out through its corresponding water injection part 130, and the water overflowing from each ice making cavity 110 can flow out in its corresponding drainage part 120 without mutual influence, realizing the independent operation of water injection, ice formation and drainage of each ice mold 100 during the ice making process. The ice maker of the present utility model can pull out one ice mold 100 at a time, and can produce up to 3 transparent ball ice at most each time. Of course, if it is not used up at one time, it can be stored in the ice making cavity 110 of the ice mold 100 continuously, and it does not affect the ice making of the remaining ice molds 100.

[0080] According to an embodiment of the present utility model, a handle 154 is provided on one side of the ice mold 100 facing the opening 560. In this embodiment, the handle 154 is provided on the ice mold 100, and the handle 154 extends towards the position where the opening 560 of the housing 500 is located. When taking ice, one can manually grasp the handle 154 and horizontally move it outside the housing 500 to pull out the ice mold 100 from the housing 500. The handle 154 can be formed on the surface of the ice mold 100 and integrally molded with the ice mold 100.

[0081] According to an embodiment of the present utility model, the ice maker further includes a cover plate 600 and a heat conduction cooling device 300. The cover plate 600 covers the opening 560, and the cover plate 600 is movably connected to the housing 500, and together with the housing 500 encloses a receiving space; the ice mold 100 is disposed in the receiving space, and a handle 154 is provided on one side of the ice mold 100 facing the cover plate 600; the heat conduction cooling device 300 is disposed in the receiving space, and the top surface of the heat conduction cooling device 300 is slidably connected to the bottom surface of the ice mold 100, so that the ice mold 100 can enter and exit the receiving space from the opening 560.

[0082] In this embodiment, the cover plate 600 is disposed on the opening 560 of the housing 500 and is movably connected to the housing 500. When the cover plate 600 covers the opening 560, the cover plate 600 and the housing 500 together enclose a receiving space. When the cover plate 600 leaves the opening 560, the opening 560 is opened, and the ice mold 100 can be taken out of or put into the receiving space. The handle 154 is disposed on the surface of the ice mold 100 corresponding to the position where the cover plate 600 is located, which is convenient for grasping the handle 154 to push or pull the ice mold 100 in or out of the opening 560.

[0083] Both the ice mold 100 and the heat conduction cooling device 300 are placed in the receiving space, and the ice mold 100 is disposed on the heat conduction cooling device 300. The bottom surface of the ice mold 100 is in contact with the top surface of the heat conduction cooling device 300. The heat conduction cooling device 300 provides the cold quantity for the ice mold 100 during ice making, and conducts the cold quantity into the ice making cavity 110 of the ice mold 100, realizing the gradual upward conduction of the cold quantity. A temperature gradient with a gradually increasing temperature from bottom to top is formed in the ice making cavity 110, so that the water has a tendency to freeze layer by layer from bottom to top, further improving the transparency of the ice making.

[0084] The ice mold 100 can be horizontally pulled out of the housing 500 from the opening 560, or can be horizontally pushed into the housing 500 from the opening 560, forming a pull-out type ice mold 100. Moreover, the ice mold 100 can slide on the heat conduction cooling device 300. Under the condition of the drawer-type entry and exit cooperation between the ice mold 100 and the housing 500, it can also ensure the normal ice making and cooling supply of the heat conduction cooling device 300 to the ice mold 100. And the relatively independent setting of the ice mold 100 and the heat conduction cooling device 300 neither hinders the implementation of their respective functions nor can realize the convenience of independent modular design, facilitating the quick removal and cleaning of the ice mold 100, and the pull-out type for quick manual ice taking, bringing the best ice making experience to the user.

[0085] According to an embodiment of the present utility model, one of a chute 311 and a protrusion 161 is provided on the bottom surface of the ice mold 100, and the other of the chute 311 and the protrusion 161 is provided on the top surface of the heat conduction device 300. The protrusion 161 is embedded in the chute 311 and can slide along the chute 311. The chute 311 extends along the orientation direction of the opening 560. In this embodiment, a sliding connection component is provided between the bottom of the ice mold 100 and the top surface of the heat conduction device 300 in sliding contact. The sliding connection component can be the cooperation of the chute 311 and the protrusion 161. The protrusion 161 is embedded in the chute 311. When the ice mold 100 slides on the heat conduction device 300, relative movement occurs between the protrusion 161 and the chute 311, while ensuring that heat transfer is always maintained between the ice mold 100 and the heat conduction device 300.

[0086] In this embodiment, the protrusion 161 is provided at the bottom of the ice mold 100, and the extending direction of the heat conduction device 300 is the length direction of the housing 500. Since the orientation of the opening 560 is perpendicular to the length direction of the housing 500, the direction for the ice mold 100 to enter and exit the housing 500 is also perpendicular to the extending direction of the heat conduction device 300. When there are multiple ice molds 100, the corresponding chutes 311 on the heat conduction device 300 are also arranged in parallel. The chute 311 is a through groove, ensuring the guidance of the independent pulling path for each ice mold 100.

[0087] According to an embodiment of the present utility model, a heat insulation layer 170 is provided on the side surface of the ice mold 100 facing the cover plate 600. In this embodiment, the heat insulation layer 170 is provided on the side surface of the ice mold 100 opposite to the cover plate 600. Through the heat insulation setting between the ice mold 100 and the cover plate 600, heat insulation is carried out at this position of the ice mold 100, isolating the influence of the external temperature on the temperature of the ice mold 100, and thus ensuring the temperature gradient formed from bottom to top in the ice making cavity 110.

[0088] According to an embodiment of the present utility model, the housing 500 includes a base 510, a surrounding plate 520, and a first heat insulation plate 530; the surrounding plate 520 surrounds the edge of the base 510, and both ends of the surrounding plate 520 have an interval to form an opening 560; the first heat insulation plate 530 is provided on the side surface of the surrounding plate 520 forming an accommodating space. In this embodiment, the housing 500 is mainly composed of the base 510, the surrounding plate 520, and the first heat insulation plate 530. The surrounding plate 520 surrounds the base 510 according to the edge of the base 510. The heat conduction device 300 and the ice mold 100 are arranged up and down in the housing 500. A certain distance is formed between the head and the tail ends of the surrounding plate 520 after surrounding the base 510, and this distance constitutes the structure of the opening 560.

[0089] To further ensure the ambient temperature of the internal space of the housing 500 and improve the heat preservation effect of the housing 500, a first heat preservation plate 530 is provided on the inner side of the surrounding plate 520. To prevent the ice-making chamber 110 of the housing from being affected and freezing, the first heat preservation plate 530 is surrounded on the side of the surrounding plate 520 where there is no opening 560 on the housing 500. The first heat preservation plate 530 can heat-insulate the internal environment of the accommodating space.

[0090] In this embodiment, the base 510 is further provided with a ventilation hole 511. The ventilation hole 511 is arranged corresponding to the position where the heat conduction device 300 is located. The cold air can contact the heat conduction device 300 through the ventilation hole 511 and exchange heat with the heat conduction columns 320 and the heat conduction plate 310 of the heat conduction device 300, so as to supply cold to the ice mold 100.

[0091] According to an embodiment of the present invention, the cover plate 600 includes a plate body 610 and a second heat preservation plate 620. The plate body 610 covers the opening 560, and the plate body 610 is rotatably connected to the base 510; the second heat preservation plate 620 is arranged on the side of the plate body 610 that forms the accommodating space. In this embodiment, the cover plate 600 is mainly composed of the plate body 610 and the second heat preservation plate 620. The plate body 610 is arranged at the opening 560 corresponding to the housing 500, and the second heat preservation plate 620 is arranged on the surface of the plate body 610 facing the housing 500. Furthermore, the first heat preservation plate 530 serves as the heat preservation plate on the inner side of the housing 500, and the second heat preservation plate 620 serves as the heat preservation plate on the inner side of the cover body, that is, a complete heat preservation plate is surrounded around the accommodating space, thereby heat-insulating the space where the ice mold 100 is located and isolating the external temperature.

[0092] In this embodiment, the lower end of the plate body 610 is rotatably connected to the edge of the base 510. When the plate body 610 rotates downward, the opening 560 is opened. When the plate body 610 rotates upward, the opening 560 is closed. The first installation hole 540 and the second installation hole 550 are both arranged on the surrounding plate 520. Both the first heat preservation plate 530 and the second heat preservation plate 620 can be made of foam material.

[0093] According to an embodiment of the present invention, the ice mold 100 includes a silica gel mold 150. The silica gel mold 150 includes a plurality of mold flap parts 151 and a folding part 152. The plurality of mold flap parts 151 surround the ice-making chamber 110, and adjacent mold flap parts 151 are connected by the folding part 152. The folding part 152 is adapted to switch between an unfolded state and a folded state. In the unfolded state, the mold flap parts 151 are dispersed and the ice-making chamber 110 is opened. In the folded state, the mold flap parts 151 are aggregated and the ice-making chamber 110 is closed. The ice-making chamber 110 is communicated with the water inlet pipe 230.

[0094] In this embodiment, the main part of the ice mold 100 is composed of a silicone mold 150. The silicone mold 150 has a certain degree of flexible deformation ability, can be bent within a certain range, and can also be restored to its original shape. The silicone mold 150 also has a certain degree of plasticity to ensure that its main shape remains unchanged. The silicone mold 150 is composed of a mold petal portion 151 and a folding portion 152. Each mold petal portion 151 is independently arranged, and multiple mold petals 151 are arranged in sequence along the circumferential direction. Adjacent mold petals 151 are connected by the folding portion 152. Each mold petal portion 151 has a recess 1511. The recesses 1511 of all mold petals 151 are combined to form an ice-making cavity 110 inside the silicone mold 150. Connecting surfaces extend from both sides of the recess 1511. The connecting surfaces between two adjacent mold petals 151 are connected by the folding portion 152. The two connecting surfaces have a sealing effect after being combined to ensure the sealing of the ice-making cavity 110.

[0095] When the ice mold 100 is making ice, the folded portion 152 is in a closed state, the mold petals 151 are gathered together, and the recesses 1511 are pieced together to form an ice cavity inside the silicone mold 150, so as to achieve the effect of closing the ice cavity 110, and then water is injected into the ice cavity 110 to make ice. After the ice making is completed, the mold petals 151 can be manually opened, that is, the mold petals 151 are bent in a direction away from the ice cavity 110, thereby driving the folded portion 152 to unfold, and the mold petals 151 are dispersed outward, so that the recesses 1511 constituting the ice cavity 110 are separated from each other, and the mold petals 151 are also separated from the ice, and the ice cavity 110 is opened, and the ice can be taken out, thereby completing manual ice defrosting.

[0096] The structural design of the silicone mold 150 does not require external force and external structure to close the ice-making chamber 110, and can be opened and ice-removed manually, which simplifies the structure of the ice mold 100, facilitates ice-removing operation, and can improve ice-making efficiency and ice-removing efficiency. Therefore, the ice mold 100 of this embodiment adopts a structural design that cooperates with the mold petal part 151 and the folding part 152, which not only realizes the generation of transparent ice of a specific shape, but also solves the problem of difficult ice removal in the traditional ice mold 100, bringing a good interactive experience.

[0097] In this embodiment, a ventilation hole is further provided on the base 510, and the ventilation hole is arranged corresponding to the position of the cooling device 300. Cold air can contact the cooling device 300 through the ventilation hole, and perform heat exchange with the cooling components and the cooling plate 310 of the cooling device 300, thereby providing cooling for the ice mold 100.

[0098] According to an embodiment of the present utility model, the ice mold 100 further includes a bottom tray 160. The silicone mold 150 is provided with a mounting groove 153, and the mounting groove 153 is correspondingly arranged below the bottom of the ice-making cavity 110. The bottom tray 160 is embedded in the mounting groove 153, and the bottom surface of the bottom tray 160 is provided with a protrusion 161. In this embodiment, the ice mold 100 is composed of the silicone mold 150 and the bottom tray 160. The silicone mold 150 serves as the upper mold, and the bottom tray 160 serves as the lower mold. The entire silicone mold 150 is located outside and above the entire bottom tray 160. The mounting groove 153 is provided at the bottom of the silicone mold 150, and the bottom tray 160 is embedded in the mounting groove 153. The lower bottom tray 160 serves as the support structure for the upper silicone mold 150. The ice-making cavity 110 is constructed inside the silicone mold 150, and the bottom tray 160 provides support force and cold quantity for the ice-making cavity 110 below the ice-making cavity 110.

[0099] A heat conduction device 300 is provided at the bottom of the ice mold 100, that is, the bottom of the silicone mold 150 is the heat conduction device 300. The bottom tray 160 can be made of a metal material, and the heat conduction performance of the metal material is higher than that of the silicone material. Therefore, the heat conduction device 300 transfers cold quantity to the bottom tray 160 and the silicone mold 150. Affected by the material, the temperature of the bottom tray 160 is lower than that of the silicone mold 150. With this design, the ice mold 100 forms a structure with a heat conduction device 300 → bottom tray 160 → silicone mold 150 where the temperature gradually increases from low to high, that is, the temperature of the heat conduction device 300 is the lowest, the temperature of the bottom tray 160 is the second lowest, and the temperature of the silicone mold 150 is the highest. The three form a certain temperature gradient environment from bottom to top.

[0100] In this embodiment, the bottom tray 160 and the silicone mold 150 can be assembled to form the ice mold 100, or the bottom tray 160 can be placed during the injection molding of silicone to form the ice mold 100 integrally. A protrusion 161 is constructed on the bottom tray 160, and it is slidably connected with the chute 311 of the heat conduction plate 310 of the heat conduction device 300.

[0101] In one embodiment, the shape of the ice-making cavity 110 is spherical, and the top surface of the bottom tray 160 is provided with a spherical groove adapted to the bottom of the ice-making cavity 110. In this embodiment, the ice-making cavity 110 can make spherical ice. To cooperate with the spherical ice-making cavity 110, a spherical groove is provided on the top surface of the bottom tray 160, that is, the bottom of the ice-making cavity 110 protrudes outward in a spherical form and is adapted to the spherical groove on the top surface of the bottom tray 160, and the bottom of the ice-making cavity 110 enters the spherical groove. There is a semi-circular silicone film with a thickness between 0.5 and 1.5 mm at the middle connection between the surrounding part of the silicone and the metal bottom tray 160, which can effectively prevent the ice ball from adhering to the metal bottom tray 160 and facilitate ice removal.

[0102] Thus, the bottom of the ice-making chamber 110 can be in a lower temperature environment, while the part of the ice-making chamber 110 not in the spherical groove is in a higher temperature part, constructing an ice-making chamber 110 with a more distinct temperature gradient change. The water at the bottom of the ice-making chamber 110 is in the lowest temperature environment, so it can freeze first and then freeze directionally from bottom to top.

[0103] In one embodiment, the silica gel mold 150 further includes a base 140, and two mold flap parts 151 are formed by the top surface of the base 140 extending upward to form protrusions 161. In this embodiment, the bottoms of the mold flap parts 151 are connected into one body through the base 140. At this time, the base 140 is the construction basis for the bottom range of the ice-making chamber 110, and the mold flap parts 151 are the parts extending upward that jointly enclose the middle and top ranges of the ice-making chamber 110. The bottom tray 160 is best made of stainless steel and aluminum as the metal lower mold. The height of the bottom tray 160 must be less than the height of the hemisphere of the surrounding part, otherwise the ice-making will not be complete.

[0104] The setting of the base 140 can not only provide a fixing and supporting basis for the mold flap parts 151, but also provide an auxiliary force for the mold flap parts 151 to recover from the curved and dispersed state to the aggregated state. Moreover, the installation groove 153 of the silica gel mold 150 also extends upward from the bottom surface of the base 140 to below the ice-making chamber 110, that is, the base 140 wraps around the outside of the bottom tray 160 to install and fix the bottom tray 160.

[0105] According to an embodiment of the present invention, the heat conduction guiding device 300 includes a heat conduction guiding plate 310 and a heat conduction guiding column 320. The heat conduction guiding plate 310 is arranged on the base 510, and a sliding groove 311 is provided on the top surface of the heat conduction guiding plate 310; the heat conduction guiding column 320 is arranged on the bottom surface of the heat conduction guiding plate 310. In this embodiment, the heat conduction guiding device 300 includes a heat conduction guiding plate 310 and a heat conduction guiding component. The heat conduction guiding component can be a fin or a heat conduction guiding column 320. The ice mold 100 is arranged on the upper surface of the heat conduction guiding plate 310, a protrusion 161 is arranged on the lower surface of the bottom tray 160 of the ice mold 100, and a sliding groove 311 is arranged on the upper surface of the heat conduction guiding plate 310, so as to realize the sliding fit connection of the ice mold 100 on the heat conduction guiding plate 310. The fin or the heat conduction guiding column 320 is arranged on the lower surface of the heat conduction guiding plate 310 to increase the heat conduction area and the cold quantity conduction efficiency. The heat conduction guiding plate 310 is generally a metal plate, and it is required that the heat conduction coefficient of the heat conduction guiding plate 310 is greater than or equal to that of the bottom tray 160 of the ice mold 100, and aluminum alloy or stainless steel can be selected.

The refrigerator body 700 includes a freezing chamber 720 and a refrigerating chamber 730. The ice maker 800 includes a housing 500, a cover plate 600, a water supply device 200, and an ice mold 100. The housing 500 has an open end 560 facing horizontally. The cover plate 600 is disposed on the open end 560 and is movably connected to the housing 500, and together with the housing 500, defines an accommodation space. The water supply device 200 includes a water tank 210 and a water inlet pipe 230. One end of the water inlet pipe 230 passes through the housing 500, and the other end of the water inlet pipe 230 is communicated with the water tank 210. An ice making cavity 110 is provided inside the ice mold 100. The ice mold 100 is provided with a water injection part 130, and the water injection part 130 is communicated with the ice making cavity 110. The water injection part 130 is detachably communicated with one end of the water inlet pipe 230 located inside the housing 500. A heat conduction device 300 is disposed at the bottom of the ice mold 100, and the ice mold 100 is slidably connected to the heat conduction device 300 so that the ice mold 100 can enter and exit the housing 500 from the open end 560 to the refrigerating chamber 730. The heat conduction device 300 is communicated with the freezing chamber 720, and the ice mold 100 is located inside the refrigerating chamber 730 or the freezing chamber 720.

[0107] In the refrigerator of the embodiment of the present utility model, the cold air system supplies cold air to the entire interior of the refrigerator. The freezing chamber 720 of the refrigerator can be used as part of the cold air system. The heat conduction device 300 is communicated to the inside of the freezing chamber 720. The cold quantity of the freezing chamber 720 is transmitted to the ice mold 100 through the heat conduction device 300. The temperature in the freezing chamber 720 is relatively low, and the ice maker 800 can make full use of the cold quantity of the freezing chamber 720 when making ice. At least the top of the ice mold 100 is located inside the refrigerating chamber 730. Therefore, as the height of the ice mold 100 changes from bottom to top, the cold quantity concentrated at the bottom of the ice mold 100 by the heat conduction device 300 can cause the temperature gradient of the ice making cavity 110 of the ice mold 100 to gradually increase from bottom to top, realizing directional freezing from bottom to top in the ice making cavity 110. Furthermore, after the ice maker 800 is integrated inside the refrigerator, the cold air system of the refrigerator is used to supply cold for ice making of the ice mold 100, without the need to provide another cold source, maximizing the utilization of resources, making the device composition more simple and integrated, and saving cold quantity.

[0108] In this embodiment, the ice mold 100 can be located in the foaming partition layer 710 between the refrigerating chamber 730 and the freezing chamber 720, and can maintain a temperature difference from bottom to top by itself, while saving space for the installation of the ice maker 800 inside the refrigerator body 700. At the same time, both the water tank 210 and the upper end of the ice mold 100 are placed in the refrigerating chamber 730, so that the waterway will not freeze. Finally, the ice mold 100 slowly forms transparent spherical ice, and ice making can be carried out cyclically.

[0109] The refrigerating chamber 730 controls the temperature at 2°C to 3°C. The higher the temperature, the longer the ice-making time. The freezing chamber 720 can control the temperature between -16°C and -24°C. Borrowing the cold air of the refrigerator requires continuous flowing and circulating cold air, which can accelerate the ice-making speed. The pull-out ice-taking design can achieve rapid ice-taking and continuous ice-making. And the ice mold 100 can make 3 transparent ice cubes at a time. If not all used up at one time, they can be left in the ice mold 100 for storage without taking them, and at the same time, it does not affect the ice mold 100 that has taken ice to continue making ice.

[0110] As Figure 8 、 Figure 9 and Figure 10 shown, according to an embodiment of the present invention, the ice maker 800 further includes a heat preservation box 840, and the water supply device 200 is arranged in the heat preservation box 840. In this embodiment, when the ice maker 800 is located in the freezing chamber 720, that is, the housing 500, the ice mold 100, the heat conduction device 300 and the water supply device 200 are all located in the freezing chamber 720. To prevent the waterway in the water supply device 200 from freezing and affecting the water supply to the ice mold 100, a heat preservation box 840 is arranged outside the water supply device 200 to control the ambient temperature where the water supply device 200 is located within a certain range to ensure that its waterway is unobstructed and does not freeze.

[0111] In this embodiment, the heat preservation box 840 can be selected as a foam material.

[0112] According to an embodiment of the present invention, the ice maker 800 further includes a heating component 810, and the heating component 810 is arranged above the ice mold 100 and is suitable for heating and raising the temperature of the space at the drainage part 120. In this embodiment, when the ice maker 800 is located in the freezing chamber 720, that is, the housing 500, the ice mold 100, the heat conduction device 300 and the water supply device 200 are all located in the freezing chamber 720. To prevent the water in the drainage part 120 of the ice mold 100 from freezing and affecting the drainage of the ice mold 100 and the waterway circulation of the ice-making chamber 110, a heating component 810 is arranged above the top of the ice mold 100. The heating component 810 heats the space around the drainage part 120, thereby controlling the ambient temperature where the drainage part 120 of the ice mold 100 is located within a certain range to ensure that its waterway is unobstructed and does not freeze.

[0113] In this embodiment, the heating component 810 can adopt a heater, a heating sheet or a heating resistance wire, etc.

[0114] According to an embodiment of the present utility model, the ice maker 800 further includes a temperature sensor 830. The temperature sensor 830 is disposed above the ice mold 100 and is adapted to detect the temperature at the top of the ice mold 100 to control the start and stop of the heating component 810. In this embodiment, since the ice maker 800 is placed in the freezing chamber 720, the internal temperature of the ice maker 800 will gradually decrease during long-term operation, affecting the upper and lower temperature gradients and preventing the freezing trend from bottom to top. A heating component 810 is arranged above the top of the ice mold 100. By monitoring the temperature at the top of the ice mold 100 through the temperature sensor 830, the start and stop of the heating component 810 are controlled, so that the temperature at the top of the ice mold 100 of the ice maker 800 is continuously controlled between 1 °C and 3 °C, reasonably controlling the temperature stability near the drainage part 120 of the ice mold 100 of the ice maker 800.

[0115] According to an embodiment of the present utility model, the ice maker 800 further includes a fan 820. The fan 820 is located above the ice mold 100 and is adapted to drive the air flow at the position of the drainage part 120. In this embodiment, when the ice maker 800 is located in the freezing chamber 720, that is, the housing 500, the ice mold 100, the heat conduction device 300, and the water supply device 200 are all located in the freezing chamber 720, the heating component 810 is disposed above the drainage part 120 of the ice mold 100, and a fan 820 is also arranged continuously above the top of the ice mold 100 in the ice maker 800 to drive the air circulation above the ice mold 100, which is beneficial to the precipitation of bubbles on the water surface at the upper end of the ice making cavity 110 of the ice mold 100, so that the ice mold 100 forms transparent spherical ice.

[0116] According to an embodiment of the present utility model, the ice maker 800 includes a top cover 400. The top cover 400 is covered on the top of the housing 500. The heating component 810, the temperature sensor 830, and the fan 820 are all installed on the side of the top cover 400 facing the ice mold 100. In this embodiment, the heating component 810, the temperature sensor 830, and the fan 820 are all fixed on the side of the top cover 400 facing the accommodating space. The top cover 400 is covered at the top opening jointly surrounded by the housing 500 and the cover plate 600, that is, the housing 500, the cover plate 600, and the top cover 400 jointly surround the accommodating space for placing the ice mold 100. At the same time, the top cover 400 provides an installation position for the heating component 810, the fan 820, and the temperature sensor 830 arranged above the ice mold 100. Therefore, the top cover 400, the heating component 810, the fan 820, and the temperature sensor 830 can be integrated into one body. When the top cover 400 is installed and connected to the housing 500, the heating component 810, the fan 820, and the temperature sensor 830 can be directly fixed and installed in place at the same time, which is beneficial to the structural integration and device simplification of the ice maker 800.

[0117] In this embodiment, a corresponding third heat insulation board 410 may be further provided on one side of the top cover 400 facing the accommodation space, and cooperate with the first heat insulation board 530 and the second heat insulation board 620 to jointly maintain the temperature of the accommodation space. The top cover 400 extends into the range of the heat insulation box 840 to cover the upper opening of the heat insulation box 840, thereby further sealing the space of the water supply device 200. Thus, the top cover 400, the cover plate 600, the housing 500 and the heat insulation box 840 form an integral outer shell surrounding the ice mold 100, the heat conduction device 300 and the water supply device 200.
