Description

Technical Field

[0001] The utility model relates to the technical field of ice making, in particular 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 static water ice-making method is in a non-transparent state, and there are bubbles inside the ice. When cooling drinks, this 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. In the existing ice-making equipment, when draining water in the ice-making cavity, a water drainage area that gathers together is often formed above. When taking ice after ice-making is completed, it is necessary to first remove the water in the large-area water drainage area. The operation is inconvenient, and it is impossible to take ice and de-ice in time, which is difficult to meet the user's needs. Moreover, in order to prevent the drainage channel from freezing during the ice-making process, heating components need to be set near the water drainage area, and the device composition is complex and inconvenient to use.

[0046] Such as Figure 1 、 Figure 2 andFigure 3 As shown in the figure, the ice maker provided by the embodiment of the present utility model includes a housing 500, a heat conduction cooling device 300, and an ice making device 400. The housing 500 is provided with an opening 530 facing the horizontal direction; the heat conduction cooling device 300 is located inside the housing 500; the ice making device 400 is located inside the housing 500, and the ice making device 400 is disposed opposite to the opening 530. The ice making device 400 is slidably connected to the heat conduction cooling device 300 so that the ice making device 400 can enter and exit the housing 500 through the opening 530.

[0047] In the ice maker of the embodiment of the present utility model, both the ice making device 400 and the heat conduction cooling device 300 are placed inside the housing 500. The housing 500 has an opening 530 facing horizontally. The heat conduction cooling device 300 provides the cold quantity for ice making of the ice making device 400. The ice making device 400 can be horizontally pulled out of the housing 500 through the opening 530 or horizontally pushed into the housing 500 through the opening 530, forming a pull-out type ice making device 400. Moreover, the ice making device 400 can slide on the heat conduction cooling device 300. Under the condition of the drawer-type entry and exit of the ice making device 400 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 making device 400. And the relatively independent setting of the ice making device 400 and the heat conduction cooling device 300 neither hinders the implementation of their respective functions nor can realize the convenience of independent modular design, which is convenient for quickly taking out the ice making device 400 for cleaning and quickly manually taking ice in a pull-out manner, bringing the best ice making experience to users.

[0048] According to an embodiment of the present utility model, the ice maker further includes a water supply device 200. The water supply device 200 is located inside the housing 500, and the water supply device 200 is communicated with the ice making device 400. In this embodiment, both the water supply device 200 and the ice making device 400 are placed in the housing 500. The water supply device 200 provides water for ice making of the ice making device 400 and can also collect the water discharged from the ice making device 400, that is, realizes the recycled water for ice making. Designing the ice making device 400, the water supply device 200, and the heat conduction cooling device 300 as integral independent modules respectively is convenient for quickly taking out the water supply device 200 and the ice making device 400 for cleaning.

[0049] As Figure 4 、 Figure 5 and Figure 6 shown, according to an embodiment of the present utility model, the ice making device 400 includes a support seat 410 and an ice mold 100. The support seat 410 is provided with a water passing part 418. The ice mold 100 is disposed on the support seat 410, and the ice mold 100 is communicated with the water passing part 418; the water supply device 200 includes a water tank 210, a water pump 230, and a hose 220. The water tank 210 is communicated with the hose 220 through the water pump 230, and the hose 220 is communicated with the water passing part 418.

[0050] In this embodiment, the ice-making device 400 is composed of an ice mold 100 and a support base 410. The water supply device 200 is composed of a water tank 210, a water pump 230, and a hose 220. One end of the hose 220 is connected to the bottom of the water tank 210, and the other end is connected to the water passage part 418 of the support base 410. The water pump 230 is arranged on the hose 220. The ice mold 100 is arranged on the support base 410 and is communicated with the water passage part 418. The water pump 230 pumps the water in the water tank 210 into the water passage part 418 through the hose 220, and the water passage part 418 can inject the water into the ice mold 100. When the ice-making device 400 enters and exits the housing 500 through the open end 530, it is the support base 410 and the ice mold 100 that enter and exit the housing 500 together, and the ice mold 100 remains fixed on the support base 410. Since the water supply pipeline is the hose 220, during the movement of the ice mold 100 and the support base 410, the hose 220 can follow the movement or generate a certain bending deformation under the drive of the water passage part 418, ensuring the water connection between the water supply device 200 and the ice-making device 400 while not affecting the pull-out fit design of the ice-making device 400 in the housing 500.

[0051] In this embodiment, the hose 220 can be a silicone hose 220, that is, the water pump 230 and the water passage part 418 are connected by the silicone hose 220. The silicone hose 220 is movable. When pulling out the ice-making device 400 to take ice, the overall water circuit remains connected all the time, reducing the risk of water leakage.

[0052] According to an embodiment of the present invention, the water pump 230 is arranged in the water tank 210. The ice mold 100 is provided with an ice-making cavity 110 and a water inlet pipe 170. The water inlet pipe 170 is communicated with the ice-making cavity 110. The hose 220 is communicated with the water inlet pipe 170 through the water passage part 418. In this embodiment, the ice mold 100 is provided with an ice-making cavity 110 and a water inlet pipe 170 communicated with the ice-making cavity 110. When the ice mold 100 is installed on the support base 410, the water inlet pipe 170 on the ice mold 100 is communicated with the water passage part 418, thereby realizing the connection between the hose 220 and the water inlet pipe 170.

[0053] Both the water pump 230 and the hose 220 can be arranged in the water tank 210, further increasing the integration and modularization of the structure of the water supply device 200. During the movement of the ice-making device 400, the moving range of the hose 220 can also be kept inside the water tank 210, without affecting the device structure outside the water tank 210. At the same time, the water tank 210 also provides protection for the hose 220.

[0054] In this embodiment, the water inlet pipe 170 can also adopt a silicone structure, having a certain bending deformation ability. The water inlet 130 of the ice mold 100 adopts an extended design to form the water inlet pipe 170. When the ice mold 100 is opened to take ice, separating the ice mold 100 to take ice will not affect the water connection, reducing the risk of water leakage.

[0055] According to an embodiment of the present utility model, a plurality of ice molds 100 are sequentially arranged along the direction in which the ice making device 400 enters and exits the housing 500. The water passing part 418 includes a first main pipeline 411, a second main pipeline 412, and a plurality of branch pipelines 413. The first main pipeline 411 is communicated with each branch pipeline 413 through the second main pipeline 412. The branch pipelines 413 are arranged in one-to-one correspondence with the ice molds 100. Each ice mold 100 is provided with a water inlet pipe 170, and the water inlet pipe 170 is detachably connected to the branch pipeline 413.

[0056] In this embodiment, the direction in which the ice making device 400 enters and exits the housing 500 is the length direction of the support seat 410. A plurality of installation positions are arranged along the length direction of the support seat 410. One ice mold 100 is correspondingly arranged at each installation position. The water passing part 418 is a water channel formed on the support seat 410 and communicating with each installation position. The water passing part 418 is mainly composed of a first main pipeline 411, a second main pipeline 412, and a plurality of branch pipelines 413. Each branch pipeline 413 is correspondingly arranged beside an installation position. The second main pipeline 412 extends along the length direction of the support seat 410 and is communicated with each branch pipeline 413. The first main pipeline 411 is communicated at the end of the second main pipeline 412 and is communicated with the hose 220, so as to realize the communication between the water supply device 200 and the water passing part 418.

[0057] The water inlet pipe 170 arranged on the ice mold 100 is detachably communicated with the branch pipeline 413, that is, when the ice mold 100 is fixed to the installation position, the water inlet pipe 170 can be hermetically inserted and communicated with the branch pipeline 413. When the ice mold 100 needs to be removed from the installation position and separated from the support seat 410, the water inlet pipe 170 can be removed from the branch pipeline 413.

[0058] According to an embodiment of the present utility model, the water passing part 418 further includes a return water pipe 414. One end of the return water pipe 414 is communicated with the second main pipeline 412, and the other end is communicated with the water tank 210. In this embodiment, the water passing part 418 is composed of a first main pipeline 411, a second main pipeline 412, a branch pipeline 413, and a return water pipe 414. The return water pipe 414 is a branch of the second main pipeline 412 and is not communicated with any ice mold 100, but is communicated with the water tank 210. When the ice mold 100 is making ice, when the water in the water inlet pipe 170 is blocked due to the influence of low temperature freezing, the water that cannot flow from the second main pipeline 412 into the branch pipeline 413 will return to the water tank 210 through the return water pipe 414, which can effectively avoid the risk of damage caused by the long-term blockage of the water pump 230 during water supply after the ice mold 100 freezes.

[0059] According to an embodiment of the present utility model, the first main pipeline 411 is fixed to one end of the support seat 410 away from the open end 530. In this embodiment, the length direction of the support seat 410 is the direction for the ice making device 400 to enter and exit the open end 530 of the housing 500. Therefore, when the ice making device 400 is located inside the housing 500, one end of the support seat 410 in the length direction is close to the open end 530, and the other end is away from the open end 530. The first main pipeline 411 is arranged at this end away from the open end 530.

[0060] In this embodiment, it is set that the length direction of the housing 500 is the direction for the ice making device 400 to enter and exit the open end 530. The surface where the open end 530 is located is the width direction of the housing 500 in the horizontal extension direction. The water tank 210 and the ice making device 400 are arranged side by side in the housing 500 along the width direction of the housing 500. The length direction of the water tank 210 is consistent with the length direction of the support seat 410. Therefore, when the first main pipeline 411 is arranged at one end of the shell support seat 410 away from the open end 530, after one end of the hose 220 is connected to the first main pipeline 411, when the support seat 410 is pulled out from the housing 500, the hose 220 can move from one end of the water pipe to the other end of the water tank 210. When the support seat 410 is pushed into the housing 500, the moving path of the hose 220 is opposite. Thus, the bending and unfolding of the hose 220 in the entire length direction of the water tank 210 are realized, the moving range of the hose 220 is expanded, and at the same time, the moving range and application effect of the ice making device 400 are improved.

[0061] In this embodiment, the first main pipeline 411 of the water tank 210 is a rigid pipeline, which is vertically fixed on the support seat 410, and its height slightly exceeds that of the water tank 210. The hose 220 extends from the water tank 210 and is communicated with the first main pipeline 411.

[0062] According to an embodiment of the present utility model, the second main pipeline 412 and the branch pipeline 413 are located inside the support seat 410. In this embodiment, both the second main pipeline 412 and the branch pipeline 413 are water channel passages formed inside the support seat 410, which further increases the structural integration degree of the support seat 410 and can be directly formed by die casting during the manufacturing process. Moreover, being arranged inside the support seat 410 can further improve the protection effect on the water channel passage, isolate the external temperature, reduce heat exchange, and avoid the effect of water channel icing.

[0063] In other embodiments, the second main pipeline 412 and the branch pipeline 413 can also be arranged as external independent pipelines on the surface of the support seat 410. This design is convenient for pipeline inspection, maintenance, and replacement.

[0064] According to an embodiment of the present utility model, the heat conduction device 300 is disposed below the support base 410. The support base 410 is provided with a first installation groove 415. The bottom of the ice mold 100 is embedded in the first installation groove 415. The bottom of the first installation groove 415 is provided with a through hole 416. The bottom of the ice mold 100 passes through the through hole 416 and is slidably connected to the heat conduction device 300. In this embodiment, the installation position on the support base 410 is set as the first installation groove 415. The ice mold 100 is installed on the support base 410 by embedding its bottom into the first installation groove 415. The bottom of the first installation groove 415 is further provided with a through hole 416 downward. The through hole 416 penetrates the support base 410. After the bottom of the ice mold 100 is embedded in the first installation groove 415, it then passes through the through hole 416 and is slidably connected to the heat conduction device 300. The heat conduction device 300 provides the cold quantity required for ice making for the ice mold 100. Thus, on the one hand, the support base 410 does not hinder the connection between the ice mold 100 and the heat conduction device 300, and on the other hand, it can integrally support and fix the ice mold 100. Through the settings of the first installation groove 415 and the through hole 416, the ice mold 100 can be in direct contact with the heat conduction device 300 for heat transfer.

[0065] In this embodiment, the heat conduction device 300 is located below the support base 410. The first installation groove 415 and the through hole 416 penetrate the support base 410 from top to bottom. The heat conduction device 300 provides the cold quantity required for ice making for the ice mold 100 through the through hole 416 and the first installation groove 415.

[0066] In an embodiment, the heat conduction device 300 includes a heat conduction plate 310 and a heat conduction component 320. The heat conduction component 320 can be a fin or a heat conduction column. The ice making device 400 is disposed on the upper surface of the heat conduction plate 310. The fin or the heat conduction column is disposed on the lower surface of the heat conduction plate 310 to increase the heat conduction area and improve the cold quantity conduction efficiency. The heat conduction plate 310 is generally a metal plate, and it is required that the heat conduction coefficient of the heat conduction plate 310 is greater than or equal to the bottom support 160 of the ice mold 100. Aluminum alloy or stainless steel can be selected.

[0067] According to an embodiment of the present utility model, one of a sliding groove 330 and a protrusion 161 is provided at the bottom of the ice mold 100 passing through the through hole 416, and the other of the sliding groove 330 and the protrusion 161 is provided on the top surface of the heat conduction device 300. The protrusion 161 is disposed in the sliding groove 330 and can move along the sliding groove 330. 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 sliding groove 330 and the protrusion 161. The protrusion 161 is embedded in the sliding groove 330. When the ice making device 400 slides on the heat conduction device 300, relative movement occurs between the protrusion 161 and the sliding groove 330, and at the same time, it is ensured that the cold quantity transfer between the ice mold 100 and the heat conduction device 300 is always maintained.

[0068] In this embodiment, a protrusion 161 is set at the bottom of the ice mold 100, which passes through the through hole 416 of the support seat 410 and enters the slide groove 330 on the upper surface of the cold guide plate 310. The slide groove 330 can be a through groove to ensure that the pulling path of the ice making device 400 is guided.

[0069] like Figure 7 , Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, the ice mold 100 includes a silicone mold 150, and the silicone mold 150 includes a plurality of mold petals 151 and a folding portion 152. The plurality of mold petals 151 surround an ice-making cavity 110, and adjacent mold petals 151 are connected by the folding portion 152. The folding portion 152 is suitable for switching between an expanded state and a closed state. In the expanded state, the mold petals 151 are dispersed and the ice-making cavity 110 is opened. In the closed state, the mold petals 151 are aggregated, the ice-making cavity 110 is closed, and the ice-making cavity 110 is connected to the water inlet pipe 170.

[0070] 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 depression. The depressions 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 depression. 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.

[0071] When the ice mold 100 is making ice, the folded portion 152 is in a closed state, the mold petals 151 are aggregated together, and the depressions are pieced together to form the ice-making cavity 110 inside the silicone mold 150, so as to achieve the effect of closing the ice-making cavity 110, and then water is injected into the ice-making cavity 110 through the water inlet pipe 170 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 the direction away from the ice-making cavity 110, thereby driving the folded portion 152 to unfold, and the mold petals 151 are dispersed outward, so that the depressions constituting the ice-making cavity 110 are separated from each other, and the mold petals 151 are also separated from the ice, and the ice-making cavity 110 is opened, and the ice can be taken out, thereby completing manual ice-defrosting.

[0072] The structural design of the silicone mold 150 can achieve the closing of the ice-making cavity 110 without external force and external structure cooperation. The ice-making cavity 110 can be opened and de-iced manually, which simplifies the structure of the ice mold 100, facilitates the manual de-icing operation, and can improve the ice-making efficiency and de-icing efficiency. Therefore, the ice mold 100 of this embodiment adopts the structural design of the cooperation between the mold flap part 151 and the folding part 152, which not only realizes the generation of transparent ice with a specific shape, but also solves the problem of difficult de-icing of the traditional ice mold 100, bringing a good interactive experience.

[0073] According to an embodiment of the present invention, the silicone mold 150 includes two mold flap parts 151 and a folding part 152. The two mold flap parts 151 enclose the ice-making cavity 110. The two 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 closed state. In the unfolded state, the two mold flap parts 151 are dispersed and the ice-making cavity 110 is opened. In the closed state, the mold flap parts 151 converge and the ice-making cavity 110 is closed. The mold flap part 151 is provided with a drain port 120 and a water inlet 130 communicating with the ice-making cavity 110.

[0074] In this embodiment, the silicone mold 150 is composed of two mold flap parts 151 and a folding part 152. The two mold flap parts 151 are arranged oppositely, and the opposite side is called the inner side. The two mold flap parts 151 are connected by the folding part 152. Both of the two mold flap parts 151 have depressions. The depressions of the two mold flap parts 151 are oppositely joined to form a complete ice-making cavity 110 inside the silicone mold 150. The edge of the depression extends out a connecting surface. The opposite connecting surfaces between the two mold flap parts 151 are connected by the folding part 152. The two connecting surfaces have a sealing effect after combination to ensure the sealing of the ice-making cavity 110.

[0075] The water inlet pipe 170 is connected to the mold flap part 151 and communicates with the water inlet 130. Water can be injected into the ice-making cavity 110 through the water inlet pipe 170 and the water inlet 130. A drain port 120 is also provided on the mold flap part 151. The water in the ice-making cavity 110 overflows to the outside of the ice mold 100 through the drain port 120, so as to form a circulating water inlet and outlet of the ice-making cavity 110.

[0076] According to an embodiment of the present invention, the mold flap part 151 includes a first extension part 1512 and an enclosing part 1511. The first extension part 1512 is connected to the top of the enclosing part 1511. The inner side of the enclosing part 1511 encloses the ice-making cavity 110. The first extension part 1512 extends above the water tank 210. The first extension part 1512 forms a drain port 120 at the highest position corresponding to the ice-making cavity 110. The upper surface of the first extension part 1512 is provided with a drain groove 140. The drain port 120 communicates with the water tank 210 through the drain groove 140.

[0077] According to an embodiment of the present utility model, an inner side surface of the surrounding portion 1511 encloses an ice-making cavity 110. A top portion of the surrounding portion 1511 horizontally extends outward to form a first extension portion 1512, and an outer edge of the first extension portion 1512 extends beyond the outer side surface of the surrounding portion 1511.

[0078] In this embodiment, the die flap portion 151 is composed of the first extension portion 1512 and the surrounding portion 1511. The first extension portion 1512 is located at the top of the surrounding portion 1511. A notch is provided at a position corresponding to the highest position of the ice-making cavity 110 inside the first extension portion 1512. Notches of two first extension portions 1512 relatively enclose a drain port 120. The notch penetrates upward from the highest position of the depression to the top surface of the first extension portion 1512. At least one of upper surfaces of the two first extension portions 1512 is provided with a drain groove 140. The drain groove 140 extends from the drain port 120 to an edge of the first extension portion 1512. The first extension portion 1512 extends above the water tank 210 so that an end of the drain groove 140 reaches above the water tank 210. The water tank 210 and the ice-making device 400 are arranged side by side. To reduce the space occupied by it in the width direction of the housing 500, the distance between the water tank 210 and the ice-making device 400 is minimized as much as possible. Therefore, the distance between the water tank 210 and the surrounding portion 1511 is minimized as much as possible, and the first extension portion 1512 directly extends above the water tank 210 by virtue of its own configuration.

[0079] In this embodiment, the ice-making cavity 110 is spherical. Therefore, the outer shape of the surrounding portion 1511 is in the shape of a hemispherical shell, the outer shape of the first extension portion 1512 is in the shape of an arc, the width of the widest part of the first extension portion 1512 is greater than the outer radius of the surrounding portion 1511, and the drain groove 140 also extends to the widest part of the first extension portion 1512.

[0080] After the water in the ice-making cavity 110 overflows from the drain port 120, it enters the drain groove 140 and flows into the water tank 210 along the drain groove 140. The water in the water tank 210 is pumped into the hose 220 by a water pump 230, and enters the water inlet pipe 170 of the ice mold 100 through the water passing portion 418 on the support seat 410 by the hose 220, and enters the water inlet 130 of the die flap portion 151 from the water inlet pipe 170, so as to inject water into the ice-making cavity 110. The water reaches the ice mold 100 from the water tank 210 and then returns to the water tank 210 from the ice mold 100, thereby realizing the water circulation ice-making of the ice-making device 400.

[0081] According to an embodiment of the present utility model, a water inlet 130 is provided at the intersection position of the surrounding portion 1511 and the first extension portion 1512. The water inlet 130 is located below the drain outlet 120. A water injection channel is provided in the first extension portion 1512, and the water injection channel is communicated with the water inlet 130. In this embodiment, the drain outlet 120 is located at the highest position of the ice making chamber 110. The position where the water inlet 130 is located is lower than the position where the drain outlet 120 is located, but both the drain outlet 120 and the water inlet 130 are concentrated at the top of the ice making chamber 110. Therefore, the water inlet 130 is arranged at the junction of the first extension portion 1512 and the surrounding portion 1511.

[0082] A water injection channel is arranged in the first extension portion 1512. One end of the water injection channel is communicated with the water inlet 130, and the other end is communicated with the water inlet pipe 170. That is, the water inlet pipe 170 is arranged at the edge of the first extension portion 1512.

[0083] According to an embodiment of the present utility model, the drain trough 140 slopes downward gradually from the water inlet 130 to the outer edge of the extension portion. In this embodiment, the drain trough 140 is formed by concave downward on the top surface of the first extension portion 1512 and extends from the drain outlet 120 to the edge of the first extension portion 1512. Water is injected into the ice making chamber 110 through the water inlet 130. After the water in the ice making chamber 110 accumulates to the highest position of the ice making chamber 110, it will overflow from the drain outlet 120. The overflowed water flows into the drain trough 140 and flows out of the ice mold 100 through the drain trough 140 and into the water tank 210. To ensure smooth flow and avoid water collection or backflow of the overflowed water in the drain trough 140, the bottom of the drain trough 140 is set as an inclined plane that slopes downward gradually along the water flow direction.

[0084] In this embodiment, by arranging the drain trough 140 at the top of each ice mold 100, all the drain troughs 140 are arranged in parallel. The water overflowed from each ice making chamber 110 can flow out in its respective corresponding drain trough 140 without mutual influence, realizing the independent operation of water injection, ice formation and drainage of each ice mold 100 during the ice making process.

[0085] It can be understood that in this embodiment, the drainage part is in an exposed state on the surface of the ice mold 100. In other embodiments, the drainage part can also be in a non-exposed state arranged inside the ice mold 100, that is, the top of the ice mold 100 has a certain thickness, and the drain outlet 120 and the drain trough 140 are in the form of internal through holes within this top range.

[0086] According to an embodiment of the present utility model, each lobe part 151 further includes a second extension part 1513. The two sides of the surrounding part 1511 extend outward to form the second extension part 1513. The top of the second extension part 1513 is connected to the first extension part 1512. The edge of the folding part 152 is connected to the outer edge of the second extension part 1513. The folding part 152 is folded and pressed between two opposite second extension parts 1513.

[0087] In this embodiment, the lobe part 151 is composed of a first extension part 1512, a surrounding part 1511, and a second extension part 1513. The edge of the surrounding part 1511 extends to form a vertical plate-like structure, which is the second extension part 1513. The connection surface is formed on the second extension part 1513. The upper end of the second extension part 1513 is connected to the first extension part 1512, forming a right-angle structure with the first extension part 1512. The side of the second extension part 1513 is connected to the surrounding part 1511. The surrounding part 1511 is between two second extension parts 1513.

[0088] After the ice mold 100 completes ice removal, the two lobe parts 151 recover and converge from the curved and dispersed state towards the direction of approaching each other, and at the same time drive the folding part 152 to fold inwards towards the ice-making cavity 110 from the unfolded state. Finally, the folding part 152 is folded between two opposite second extension parts 1513. In the state where the ice-making cavity 110 is closed, the folding part 152 is folded and pressed between two opposite second extension parts 1513, which can fill the gap formed between the two lobe parts 151. On the one hand, it can meet the closing shape requirements of the ice-making cavity 110 and prevent water from entering the gap and freezing, resulting in a change in the ice shape. On the other hand, it can make the external structure of the ice mold 100 more integrated and simple, and can save the space occupation amount in the arrangement of multiple ice molds 100.

[0089] According to an embodiment of the present utility model, a drainage groove 140 is provided on the upper surface of one first extension part 1512, and the upper surface of the other first extension part 1512 is flush with the bottom surface of the drainage groove 140. In this embodiment, the two lobe parts 151 are respectively a first lobe part 151 and a second lobe part 151. The first lobe part 151 is close to the water tank 210. The drainage groove 140 is provided on the first extension part 1512 of the first lobe part 151. The drainage groove 140 is not provided on the first extension part 1512 of the second lobe part 151. The upper surface of the first extension part 1512 of the second template part is flush with the bottom surface of the drainage groove 140.

[0090] The edge of the first extension portion 1512 is provided with a retaining edge. After the water in the ice-making cavity 110 overflows from the drain port 120, in order to ensure that the water can only flow on the top surface of the ice mold 100 and flow into the water tank 210 as soon as possible, a retaining edge is provided to enclose the upper surface of the first extension portion 1512. When the drain port 120 discharges water, the upper surface of the first extension portion 1512 of the second die flap portion 151 provides sufficient overflow flow space for the water. Then, the water on the upper surface of the first extension portion 1512 of the second die flap portion 151 can converge to the drain groove 140 and then flow into the water tank 210 from the drain groove 140.

[0091] According to an embodiment of the present invention, the ice mold 100 further includes a bottom support 160. The silicone mold 150 is provided with a fixing groove 1531, and the fixing groove 1531 is correspondingly arranged below the bottom of the ice-making cavity 110. The bottom support 160 is embedded in the fixing groove 1531. In this embodiment, the ice mold 100 is composed of the silicone mold 150 and the bottom support 160. The silicone mold 150 serves as the upper mold, and the bottom support 160 serves as the lower mold. The whole silicone mold 150 is located outside and above the whole bottom support 160. The fixing groove 1531 is arranged at the bottom of the silicone mold 150, and the bottom support 160 is embedded in the fixing groove 1531. The lower bottom support 160 serves as the support structure of the upper silicone mold 150. The ice-making cavity 110 is constructed inside the silicone mold 150, and the bottom support 160 provides support force and cold quantity for the ice-making cavity 110 below the ice-making cavity 110.

[0092] A heat conduction device 300 is arranged 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 support 160 can be made of a metal material. 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 support 160 and the silicone mold 150. Affected by the material, the temperature of the bottom support 160 is lower than that of the silicone mold 150. With this design, the ice mold 100 forms a structure of heat conduction device 300 → bottom support 160 → silicone mold 150 with a temperature from low to high, that is, the temperature of the heat conduction device 300 is the lowest, the bottom support 160 is the second, and the temperature of the silicone mold 150 is the highest. The three form a certain temperature gradient environment from bottom to top.

[0093] In this embodiment, the bottom support 160 and the silicone mold 150 can be assembled to form the ice mold 100, or the bottom support 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 support 160 and is slidably connected with the chute 330 of the heat conduction plate 310 of the heat conduction device 300.

[0094] In one embodiment, the shape of the ice-making cavity 110 is spherical, and a spherical groove adapted to the bottom of the ice-making cavity 110 is provided on the top surface of the bottom tray 160. 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 silica gel film with a thickness between 0.5 and 1.5 mm at the middle connection between the silica gel surrounding portion 1511 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.

[0095] Thus, the bottom of the ice-making cavity 110 can be in a lower temperature environment, and the part of the ice-making cavity 110 that is not in the spherical groove is in a higher temperature part, constructing an ice-making cavity 110 with a more distinct temperature gradient change. The water at the bottom of the ice-making cavity 110 is in the lowest temperature environment, so it can freeze first and then freeze directionally from bottom to top.

[0096] In one embodiment, the silica gel mold 150 further includes a base portion 153, and two mold flap portions 151 are formed by the upward extension of the convex 161 on the top surface of the base portion 153. In this embodiment, the bottoms of the respective mold flap portions 151 are connected into one body through the base portion 153. At this time, the base portion 153 is the construction basis for the bottom range of the ice-making cavity 110, and the mold flap portions 151 are the upward extended parts that jointly enclose the middle and top ranges of the ice-making cavity 110. The bottom tray 160 is preferably made of 304 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 portion 1511, otherwise the ice cannot be made thoroughly.

[0097] The setting of the base portion 153 can not only provide a fixing and supporting basis for the mold flap portions 151, but also provide an auxiliary force for the mold flap portions 151 to recover from the curved and dispersed state to the aggregated state. Moreover, the fixing groove 1531 of the silica gel mold 150 also extends upward from the bottom surface of the base portion 153 to below the ice-making cavity 110, that is, the base portion 153 is wrapped around the outside of the bottom tray 160 to install and fix the bottom tray 160.

[0098] According to an embodiment of the present invention, the support base 410 is provided with a second installation groove 417. The second installation groove 417 surrounds the outside of the first installation groove 415, and the second installation groove 417 is filled with a second heat-insulating material 419. In this embodiment, a second installation groove 417 is provided outside the first installation groove 415 of the support base 410. The second installation groove 417 surrounds the first installation groove 415, and the second installation groove 417 is filled with the second heat-insulating material 419. Through the heat-insulating setting of the second installation groove 417, heat insulation is carried out on the position of the first installation groove 415 to isolate the influence of the external temperature on the temperature at the first installation groove 415. Since the first installation groove 415 cooperates with the through hole 416 at the bottom of the groove to communicate with the heat-conducting device 300, the bottom support 160 of the ice mold 100 contacts the heat-conducting component 320 through the first installation groove 415 and the through hole 416. The second heat-insulating material 419 in the second installation groove 417 can ensure the heat-conducting environment between the ice mold 100 and the heat-conducting device 300.

[0099] According to an embodiment of the present invention, the support base 410 includes a base 420, a panel 430 and a second heat-insulating board 440. The panel 430 is arranged on the base 420, and the ice mold 100 is located on the base 420. The panel 430 seals the open end 530, and the heat-insulating board is arranged on the side of the panel 430 facing the ice mold 100. In this embodiment, the support base 410 is mainly composed of a base 420, a panel 430 and a second heat-insulating board 440. The base 420 is horizontally arranged, the panel 430 and the second heat-insulating board 440 are vertically arranged, the ice mold 100 is installed on the base 420, and both the first installation groove 415 and the second installation groove 417 are arranged on the base 420. The length direction of the base 420 is the direction in which the ice-making device 400 enters and exits the open end 530. When the ice mold 100 is located inside the housing 500, the position where the panel 430 is located is the open end 530 position. Therefore, after the ice-making device 400 is pushed into the housing 500, the panel 430 seals the open end 530 of the housing 500, thereby making the internal space of the housing 500 relatively independently sealed. The second heat-insulating board 440 is arranged on the side of the bread facing the inside of the housing 500 to ensure that the panel 430 and the housing 500 form a sealed whole and improve the heat-insulating structure of the housing 500 at the panel 430 to ensure the temperature of the ice-making environment.

[0100] In this embodiment, when the ice mold 100 finishes making ice, pulling out the panel 430 from the housing 500 drives the base 420 and the ice mold 100 on the base 420 to move simultaneously.

[0101] According to an embodiment of the present invention, the housing 500 includes a base 510 and a surrounding plate 520. The base 510 includes a first installation area 511 and a second installation area 512. The heat-conducting device 300 is arranged in the first installation area 511, and the water supply device 200 is arranged in the second installation area 512. 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 open end 530.

[0102] In this embodiment, the housing 500 is mainly composed of a base 510 and a surrounding plate 520. The surrounding plate 520 surrounds the base 510 along the edge of the base 510. The water supply device 200 and the ice making device 400 are arranged side by side in the housing 500, and the ice making device 400 and the heat conduction cooling device 300 are arranged vertically in the housing 500. Thus, the base 510 is divided into two installation areas. The first installation area 511 installs the heat conduction cooling device 300 and the ice making device 400, and the second installation area 512 installs the water supply device 200. The surrounding plate 520 surrounds the base 510, and a certain distance is formed between the head and tail ends of the surrounding plate 520 after surrounding the base 510, and this distance constitutes the open structure 530. Thus, the relatively independently partitioned and installed water supply device 200, heat conduction cooling device 300 and ice making device 400 are integrated in the housing 500, further improving the modularization and integration of the ice maker, simplifying the structure, reducing the occupied space, facilitating ice making and ice taking, and bringing a good interactive experience.

[0103] In this embodiment, the base 510 is also provided with a ventilation hole 513, and the ventilation hole 513 is arranged corresponding to the position where the heat conduction cooling device 300 is located. Cold air can contact the heat conduction cooling device 300 through the ventilation hole 513 and perform heat exchange with the heat conduction components 320 and the heat conduction plate 310 of the heat conduction cooling device 300, so as to supply cold to the ice making device 400.

[0104] According to an embodiment of the present invention, the housing 500 further includes a first heat preservation board 540, and the first heat preservation board 540 is arranged around the edge of the second installation area 512. In this embodiment, in order to further ensure the environmental temperature of the internal space of the housing 500 and improve the heat preservation effect of the housing 500, a part of the surrounding plate 520 corresponding to the second installation area 512 is provided with the first heat preservation board 540, and the first heat preservation board 540 is arranged on the inner side surface of the surrounding plate 520. The water supply device 200 is arranged at the second installation area 512. To prevent the water supply device 200 from freezing due to the influence of the external low temperature, the first heat preservation board 540 is arranged around the side surface of the water tank 210 that is not opposite to the ice making device 400, and the first heat preservation board 540 can keep the internal environment of the water tank 210 warm.

[0105] According to an embodiment of the present utility model, a first convex portion 521 is provided on the inner side of the surrounding plate 520 close to the first installation area 511. The side surface of the first convex portion 521 is adapted to the outer shape of the ice mold 100. A first sliding track 522 is defined by the lower surface of the first convex portion 521, the surrounding plate 520 and the base 510, and the support seat 410 can slide along the first sliding track 522. In this embodiment, the first convex portion 521 is provided on the inner side of the surrounding plate 520 facing the ice making device 400. The first convex portion 521 is a bent portion, and the outer shape after bending matches the outer shape of the surrounding portion 1511 of the ice mold 100. The lower surface of the first convex portion 521, the side surface of the surrounding plate 520 below the first convex portion 521 and the base 510 of the housing 500 can define the first sliding track 522. The edge of the support seat 410 is embedded in the first sliding track 522, and during the process of the ice making device 400 entering and exiting the housing 500, the support seat 410 slides along the first sliding track 522.

[0106] The first sliding track 522 guides and positions the movement of the ice making device 400. The first convex portion 521 matches the outer shape of the surrounding portion 1511, maintaining the stability of the ice mold 100 during movement while not interfering with the movement routes of the ice mold 100 and the support seat 410.

[0107] According to an embodiment of the present utility model, a first heat insulating material 550 is filled between the surrounding plate 520 and the first convex portion 521. In this embodiment, the first convex portion 521 is a bent component, and there is a certain space between the surface of the first convex portion 521 and the surrounding plate 520 after bending. In order to further ensure the environmental temperature of the internal space of the housing 500 and improve the heat insulation effect of the housing 500, the first heat insulating material 550 is filled in this space. The first convex portion 521 corresponds to the surrounding portion 1511 of the ice mold 100. Setting the first heat insulating material 550 at the position of the first convex portion 521 is equivalent to increasing the thickness and heat insulation performance of the surrounding plate 520 itself, avoiding the surrounding portion 1511 being affected by the external temperature and unable to maintain the temperature gradient of the ice making cavity 110.

[0108] According to an embodiment of the present utility model, the water supply device 200 includes a bottom box 240. The bottom of the water tank 210 is inserted into the bottom box 240. One side of the water tank 210 close to the first installation area 511 is configured as a second convex portion 211. The side surface of the second convex portion 211 is adapted to the outer shape of the ice mold 100. A second sliding track 212 is defined by the lower surface of the second convex portion 211, the bottom box 240 and the base 510, and the support seat 410 can slide along the second sliding track 212.

[0109] In this embodiment, the bottom box 240 is located below the water tank 210, which is equivalent to suspending the water tank 210, and also has the effect of ensuring the ambient temperature at the bottom of the water tank 210, avoiding the water inside the water tank 210 from freezing. One side of the water tank 210 close to the ice mold 100 is directly configured as the second convex part 211. The second convex part 211 is a bent part, and the outer shape after bending is also the same as the outer shape of the surrounding part 1511 that matches the ice mold 100. The lower surface of the second convex part 211, the side surface of the water tank 210 below the second convex part 211, and the base 510 of the housing 500 can enclose the second slideway 212. The edge of the support seat 410 is embedded in the second slideway 212, and during the process of the ice making device 400 entering and exiting the housing 500, the support seat 410 slides along the second slideway 212.

[0110] The second slideway 212 guides and positions the movement of the ice making device 400. The second convex part 211 matches the outer shape of the surrounding part 1511 to maintain the stability of the ice mold 100 during movement, while not interfering with the movement routes of the ice mold 100 and the support seat 410. At the same time, it also makes the water tank 210 move closer to the position where the ice mold 100 is located, reducing the distance between the water tank 210 and the ice mold 100.

[0111] In one embodiment, the water supply device 200 further includes a top cover 250, the top cover 250 is covered on the upper opening of the water tank 210, and the housing 500 is also provided with an upper cover 560, the upper cover 560 is covered above the surrounding plate 520, so that the surrounding plate 520, the base 510 and the upper cover 560 form an accommodation space.

[0112] The ice making in the embodiment of the present utility model can make transparent ice. The specific steps are as follows: by continuously inputting cold air to the bottom metal cold guide plate 310, conducting the cold air to the metal bottom tray 160 and then to the ice making cavity 110 of the silica gel mold 150, realizing the gradual upward conduction of the cold air, and forming a temperature gradient in the ice making cavity 110 where the temperature gradually increases from bottom to top, so that the water has a tendency to freeze layer by layer from bottom to top; at the same time, during the ice making process, the water pump 230 continuously conducts the water in the water tank 210 through the hose 220 to the water passing part 418, and then enters the water inlet pipe 170 of the silica gel mold 150. When the water in the silica gel mold 150 overflows, it will flow back to the water tank 210 from the first extension part 1512 of the ice mold 100. The water pump 230 works all the time during the ice making process, so as to realize circulating flowing water ice making, and gradually remove the air bubbles in the water in the ice making cavity 110 during the ice making process to realize transparent spherical ice.

[0113] In this embodiment, the water pump 230 works for a long time, and the actual flow rate of the water entering a single ice mold 100 is controlled to be 80 mL / min - 180 mL / min. The larger the flow rate, the more transparent the ice is, and the slower the ice freezes. The actual selection is controlled to be 90 mL / min, and the ice making time is 12 hours.

[0114] Such asFigure 10 As shown in the figure, an embodiment of the present utility model further provides a refrigerator, which includes a refrigerator body 600 and an ice maker 700 as described in the above embodiment. The refrigerator body 600 includes a freezing chamber 610 and a refrigerating chamber 620; the ice maker 700 includes a housing 500, a cold conduction device 300 and an ice making device 400 located inside the housing 500. The housing 500 is provided with an opening 530 facing the horizontal direction. The ice making device 400 is disposed opposite to the opening 530. The cold conduction device 300 is disposed at the bottom of the ice making device 400, and the ice making device 400 is slidably connected to the cold conduction device 300 so that the ice making device 400 can enter and exit the housing 500 through the opening 530. The cold conduction device 300 is communicated with the freezing chamber 610, and at least the top of the ice making device 400 is located inside the refrigerating chamber 620.

[0115] In the refrigerator according to the embodiment of the present utility model, the cold air system supplies cold air to the entire interior of the refrigerator. The freezer of the refrigerator can be used as a part of the cold air system. The cold conduction device 300 is communicated to the inside of the freezing chamber 610. The cold quantity in the freezer is transmitted to the ice making device 400 through the cold conduction device 300. The temperature in the freezer is relatively low, and the ice maker 700 can make full use of the cold quantity in the freezer when making ice. At least the top of the ice making device 400 is located inside the refrigerating chamber 620. 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 cold conduction device 300 can cause a gradually increasing temperature gradient change in the ice making cavity 110 of the ice mold 100 from bottom to top, realizing directional freezing from bottom to top in the ice making cavity 110. Furthermore, after the ice maker 700 is integrated inside the refrigerator, the cold air system of the refrigerator is used to supply cold for ice making in the ice mold 100, without the need to provide another cold source, maximizing the utilization of resources, making the device composition simpler and more integrated, and saving cold quantity.

[0116] In this embodiment, the ice making device 400 can be located in the foaming interlayer 630 between the refrigerating chamber 620 and the freezing chamber 610. The heat insulation layer itself can maintain the temperature difference from bottom to top, and at the same time can save space for the installation of the ice maker 700 in the refrigerator body 600. At the same time, both the upper ends of the water tank 210 and the ice mold 100 are placed in the refrigerating chamber 620, so that the waterway will not freeze. Finally, the ice making device 400 gradually forms transparent spherical ice, and can make ice in a cycle.

[0117] The temperature of the refrigerating chamber 620 is controlled at 2 - 3°C. A higher temperature will lengthen the ice making time. The temperature of the freezing chamber 610 can be controlled between -16°C and -24°C. Borrowing the cold air of the refrigerator requires continuous flow and circulation of 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 making device 400 can make 3 transparent ice cubes at a time. If not all the ice is used up at one time, it can be left in the ice mold 100 for storage without affecting the ice making device 400 that has taken ice to continue making ice.

[0118] According to an embodiment of the present utility model, the water tank 210 is located in the refrigerating chamber 620. In this embodiment, the water tank 210 is arranged in the refrigerating chamber 620 to ensure that the water in the water tank 210 does not freeze as much as possible. At the same time, when it is arranged in the freezing chamber 610 or the foaming insulation layer 630, in order to avoid poor heat insulation effect, a structure with multiple heat insulation layers needs to be added, and the volume is minimized.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered by the scope of the claims of the present utility model.
