Its main function is to convert the high-temperature and high-pressure gaseous refrigerant discharged by the compressor into liquid refrigerant through the condensation process. In order to make the ice machine have a better heat exchange effect, the size of the condenser is generally designed to be larger, and the condensation effect of the refrigerant is improved by using longer copper tubes and larger heat dissipation fins. Such a design will increase the overall size and manufacturing cost of the ice machine. Summary of the invention

[0003] In view of this, the present application provides an ice maker to solve the problem of the large volume of the condenser of the ice maker in the prior art.

[0004] A first aspect of the present application provides an ice maker, the ice maker comprising: an inner tank, the interior of the inner tank forming a refrigeration chamber of the ice maker; a refrigeration system, the refrigeration system comprising an evaporator and a condenser, the evaporator being arranged to be in thermal contact with the inner tank for refrigerating the refrigeration chamber, and the condenser being arranged to be spaced apart from the inner tank; a heat dissipation system, the heat dissipation system being arranged to be able to connect the refrigeration chamber and the condenser, for passing part of the cold air in the refrigeration chamber to the condenser and dissipating the heat of the condenser.

[0005] Beneficial effects: The present application proposes to dissipate heat for the condenser through the cold air in the inner tank, thereby alleviating the heat dissipation burden of the condenser and effectively solving the problem of the ice maker's condenser being too large, thereby reducing the overall size and volume of the ice maker, reducing the overall cost of the ice maker, and improving the market competitiveness of the ice maker; at the same time, dissipating heat for the condenser through the cold air in the inner tank can improve the ice making performance, energy efficiency ratio and service life of the ice maker.

[0006] Specifically, by setting up a heat dissipation system connecting the refrigeration chamber and the condenser inside the ice maker, the heat dissipation system can drain and discharge the low-temperature gas in the inner tank of the ice maker to the condenser, so that the ambient temperature of the condenser is reduced, thereby improving the heat exchange efficiency of the condenser, achieving a high-efficiency heat exchange effect of the condenser, thereby reducing the volume of the condenser of the ice maker and reducing the overall volume and cost of the ice maker.

[0008] Beneficial effect: Since the inner tank requires a colder environment and the temperature of the condenser is relatively high, in order to reduce the influence of the condenser on the temperature of the inner tank, a larger distance is generally set between the condenser and the inner tank. For example, the embodiment of the present application proposes to set the inner tank at the top of the ice maker and the condenser at the bottom of the ice maker, and then transport the cold air in the inner tank to the condenser through a conduit, so as to cool the condenser and improve the condensation effect of the condenser on the refrigerant.

[0009] Furthermore, the embodiment of the present application proposes to dissipate heat for the condenser through a heat dissipation frame assembly. Since the heat dissipation frame assembly has a larger heat dissipation surface, the heat dissipation effect and heat dissipation uniformity of the heat dissipation frame assembly on the condenser can be improved, and the phenomenon of local uneven heat dissipation of the condenser can be reduced.

[0010] In an optional embodiment, the heat dissipation frame assembly includes a first heat dissipation frame and a second heat dissipation frame, the second heat dissipation frame is against one side of the condenser and is provided with heat dissipation holes, the first heat dissipation frame is attached to the second heat dissipation frame and is respectively connected to the conduit and the second heat dissipation frame.

[0011] Beneficial effects: The embodiment of the present application proposes to perform two-stage diversion of the cold air in the duct through two heat dissipation racks, so as to achieve the purpose of gradually diffusing the cold air in the duct, thereby improving the heat dissipation effect and heat dissipation uniformity of the cold air in the duct.

[0012] Furthermore, the size of the first heat dissipation frame is smaller than that of the second heat dissipation frame, so as to achieve the purpose of step-by-step diversion of the cold air in the duct. The second heat dissipation frame is against one side of the condenser and can also support and limit the condenser.

[0013] In an optional embodiment, the first heat dissipation frame is configured as a semi-frame heat dissipation frame, the outer wall of the first heat dissipation frame is provided with a first air inlet hole, the interior of the first heat dissipation frame is provided with a first air duct connected to the first air inlet hole, and the inner wall of the first heat dissipation frame is provided with a plurality of first air outlet holes connected to the first air duct.

[0016] Beneficial effect: The second heat dissipation rack abuts against the periphery of the condenser, and can pass cold air to the periphery of the condenser, thereby improving the heat dissipation efficiency and heat dissipation uniformity of the heat dissipation rack assembly to the condenser. Furthermore, the second heat dissipation rack abuts against one side of the condenser, and can also play a role in supporting and limiting the condenser.

[0017] In an optional embodiment, the ice maker further includes a fan, and the fan and the heat dissipation system are respectively distributed on both sides of the condenser, and the fan is used to discharge part of the cold air generated by the heat dissipation system through the condenser through the fan.

[0018] Beneficial effect: A bracket is installed on the side of the condenser facing away from the heat sink assembly, and the bracket is connected to the fan of the ice maker. When the fan is working, the low-temperature gas in the inner tank can be sucked and blown to the condenser. The low-temperature gas quickly reduces the surface temperature of the condenser tube and the heat dissipation fins of the condenser, so that the refrigerant in the condenser tube can be condensed and converted into liquid refrigerant more quickly. Therefore, the ice maker provided by the implementation of this application can be designed with a smaller condenser, and a shorter condenser tube and smaller heat dissipation fins can also quickly condense the refrigerant, realizing a small-volume and efficient condenser design.

The low-temperature gas in the inner tank can be blown to the condenser through the air holes and the conduit in turn, so that the temperature of the condenser tube and the heat dissipation fins of the condenser is quickly reduced. When the ice maker completes ice making or shuts down, the controller of the ice maker sends a signal, the driving device starts, and drives the cover plate to move to the position of closing the air holes of the inner tank, thereby achieving the purpose of maintaining the temperature of the inner tank at a low temperature.

[0021] In an optional embodiment, the switch mechanism includes a drive device and a cover plate, and the drive device is configured to be connected to the cover plate and is used to drive the cover plate to cover the air hole or open the air hole.

[0022] Beneficial effect: When the ice maker starts to make ice, the compressor of the ice maker starts to work. After the driving device of the inner tank receives the ice making signal, the cover plate set on the inner tank opens the air holes of the inner tank.

When the ice maker completes ice making or shuts down, the controller of the ice maker sends a signal, the driving device starts, and drives the cover plate to move to the position of closing the air holes of the inner tank, thereby achieving the purpose of maintaining the temperature of the inner tank at a low temperature.

[0023] The second aspect of the present application provides a control method for an ice maker, which is implemented by the ice maker of the first aspect of the present application, and the control method includes: obtaining the state of the ice maker; controlling a driving device to drive a cover plate to open the air hole according to whether the ice maker is in an ice-making condition; and controlling a driving device to drive a cover plate to close the air hole according to whether the ice maker is in a heat preservation condition or a shutdown condition.

[0024] Beneficial effect: The ice-making machine of the embodiment of the present application proposes to dissipate heat for the condenser through the cold air in the inner tank, which effectively solves the problem of the excessive size of the condenser of the ice-making machine, thereby reducing the overall size and volume of the ice-making machine, reducing the overall cost of the ice-making machine, and improving the market competitiveness of the ice-making machine; at the same time, dissipating heat for the condenser through the cold air in the inner tank can improve the ice-making performance, energy efficiency ratio and service life of the ice-making machine.

[0026] Beneficial effect: The low-temperature gas in the inner tank can be blown to the condenser through the conduit. In order to reduce the insufficient cooling capacity of the inner tank or the failure of ice making, the embodiment of the present application proposes to accurately control the size of the pores and the loss of cold air, so that the inner tank of the ice maker can continue to make ice at a low temperature during the ice making process. The cooling capacity during ice making can ensure the low temperature of the cavity of the inner tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0046] like Figures 1 to 7 As shown, according to an embodiment of the present application, the present application provides an ice maker 100, which includes: an inner tank 10, the interior of the inner tank 10 forms a refrigeration chamber of the ice maker 100; a refrigeration system, the refrigeration system includes an evaporator 20 and a condenser 30, the evaporator 20 is configured to be in thermal contact with the inner tank 10, and is used to refrigerate the refrigeration chamber, and the condenser 30 is configured to be spaced apart from the inner tank 10; a heat dissipation system 40, the heat dissipation system 40 is configured to be able to connect the refrigeration chamber and the condenser 30, and is used to pass part of the cold air in the refrigeration chamber into the condenser 30, and dissipate heat from the condenser 30.

[0047] In the present embodiment, the ice maker 100 of the present application embodiment proposes to dissipate heat for the condenser 30 through the cold air of the inner tank 10, which effectively solves the problem that the condenser 30 of the ice maker 100 is too large, thereby reducing the overall size and volume of the ice maker 100, reducing the overall cost of the ice maker 100, and improving the market competitiveness of the ice maker 100; at the same time, dissipating heat for the condenser 30 through the cold air of the inner tank 10 can improve the ice making performance, energy efficiency ratio and service life of the ice maker 100.

[0048] Specifically, by setting a heat dissipation system 40 connecting the refrigeration chamber and the condenser 30 inside the ice maker 100, the heat dissipation system 40 can drain and discharge the low-temperature gas in the inner tank 10 of the ice maker 100 to the condenser 30, so that the ambient temperature of the condenser 30 is reduced, thereby improving the heat exchange efficiency of the condenser 30, achieving efficient heat exchange of the condenser 30, thereby reducing the volume of the condenser 30 of the ice maker 100, and reducing the overall volume and cost of the ice maker 100.

[0049] It should be noted that in this embodiment, the specific structure and installation position of the heat dissipation system 40 are not limited because the specific structure of the heat dissipation system 40 needs to be coordinated with the shape structure and use environment of the ice maker 100. The shape structure of the heat dissipation system 40 includes a tubular structure, a heat dissipation frame structure, and an inner wall air duct structure; the heat dissipation system 40 can be installed to the bottom of the ice maker 100 or to the inner wall of the ice maker 100. The above-mentioned specific structure and the above-mentioned installation position of the heat dissipation system 40 belong to the protection scope of the embodiment of the present application, and the above-mentioned specific structure and the above-mentioned installation position of the heat dissipation system 40 will be described in detail below.

[0050] like Figures 3 to 5 As shown, in some embodiments, the heat dissipation system 40 includes a conduit 41 and a heat dissipation frame assembly 42, and the two ends of the conduit 41 are respectively connected to the refrigeration chamber and the heat dissipation frame assembly 42, and the heat dissipation frame assembly 42 is arranged at the condenser 30, and the heat dissipation frame assembly 42 is provided with heat dissipation holes 423 corresponding to the condenser 30.

[0051] In the above embodiment, since the inner tank 10 requires a colder environment and the temperature of the condenser 30 is relatively high, in order to reduce the temperature influence of the condenser 30 on the inner tank 10, a larger distance is generally provided between the condenser 30 and the inner tank 10. For example, the embodiment of the present application proposes to dispose the inner tank 10 at the top of the ice maker 100 and the condenser 30 at the bottom of the ice maker 100, and then transport the cold air in the inner tank 10 to the condenser 30 through the conduit 41, so as to cool the condenser 30 and improve the condensation effect of the condenser 30 on the refrigerant.

[0052] Furthermore, the embodiment of the present application proposes to dissipate heat for the condenser 30 through the heat dissipation frame assembly 42. Since the heat dissipation frame assembly 42 has a larger heat dissipation surface, the heat dissipation effect and heat dissipation uniformity of the heat dissipation frame assembly 42 on the condenser 30 can be improved, and the phenomenon of local uneven heat dissipation of the condenser 30 can be reduced.

[0053] like Figures 3 to 5As shown, in some embodiments, the heat dissipation frame assembly 42 includes a first heat dissipation frame 421 and a second heat dissipation frame 422. The second heat dissipation frame 422 is against one side of the condenser 30 and is provided with heat dissipation holes 423. The first heat dissipation frame 421 is attached to the second heat dissipation frame 422 and is connected to the duct 41 and the second heat dissipation frame 422 respectively.

[0054] In the above embodiment, the embodiment of the present application proposes to perform two-stage diversion of the cold air in the duct 41 through two heat dissipation racks, so as to achieve the purpose of gradually diffusing the cold air in the duct 41, thereby improving the heat dissipation effect and heat dissipation uniformity of the cold air in the duct 41.

[0055] Furthermore, the size of the first heat dissipation frame 421 is smaller than that of the second heat dissipation frame 422 , so as to achieve the purpose of step-by-step diversion of the cold air in the duct 41 . The second heat dissipation frame 422 abuts against one side of the condenser 30 , and can also support and limit the condenser 30 .

[0056] like Figures 3 to 5 As shown, in some optional embodiments, the first heat dissipation frame 421 is configured as a semi-frame heat dissipation frame, the outer wall of the first heat dissipation frame 421 is provided with a first air inlet hole, the interior of the first heat dissipation frame 421 is provided with a first air duct connected to the first air inlet hole, and the inner wall of the first heat dissipation frame 421 is provided with a plurality of first air outlet holes connected to the first air duct.

[0057] In this embodiment, the first heat sink 421 is configured as a concave half-frame heat sink, and the three surfaces of the half-frame heat sink are tightly fitted with the second heat sink 422. The three surfaces of the half-frame heat sink are provided with multiple first air outlets evenly distributed. The second heat sink 422 is configured as a full-frame heat sink, and the second heat sink 422 is provided with multiple heat dissipation holes 423 evenly distributed around it, so as to achieve the purpose of step-by-step diversion of the cold air in the duct 41, thereby improving the heat dissipation efficiency and heat dissipation uniformity of the heat sink assembly 42 to the condenser 30.

[0058] like Figures 3 to 5 As shown, in some embodiments, the second heat dissipation frame 422 is configured as a whole-frame heat dissipation frame, the second heat dissipation frame 422 is against the periphery of the condenser 30, the outer wall of the second heat dissipation frame 422 is provided with a second air inlet hole connected to the first air outlet hole, the interior of the second heat dissipation frame 422 is provided with a second air duct connected to the second air inlet hole, and the inner wall of the second heat dissipation frame 422 is provided with a plurality of heat dissipation holes 423 connected to the second air duct.

[0059] In the above embodiment, the second heat dissipation frame 422 abuts against the periphery of the condenser 30, and can pass cold air to the periphery of the condenser 30, thereby improving the heat dissipation efficiency and heat dissipation uniformity of the heat dissipation frame assembly 42 to the condenser 30. Furthermore, the second heat dissipation frame 422 abuts against one side of the condenser 30, and can also play a role in supporting and limiting the condenser 30. The two ends of the condenser 30 are limited by the limiting plate 303, and cooperate with the second heat dissipation frame 422 to achieve the effect of fully supporting and limiting the condenser 30.

[0060] like Figures 3 to 7 As shown, in some embodiments, the ice maker 100 further includes a fan 32 , and the fan 32 and the heat dissipation system 40 are respectively distributed on both sides of the condenser 30 , and the fan 32 is used to discharge part of the cold air generated by the heat dissipation system 40 through the condenser 30 through the fan 32 .

[0061] In the above embodiment, a bracket 31 is installed on the side of the condenser 30 facing away from the heat dissipation frame assembly 42. The bracket 31 is connected to the fan 32 of the ice maker 100. When the fan 32 is working, the low-temperature gas in the inner tank 10 can be sucked and blown toward the condenser 30. The low-temperature gas causes the surface temperature of the condenser tube 301 and the heat dissipation fins 302 of the condenser 30 to drop rapidly, so that the refrigerant in the condenser tube 301 can be condensed and converted into liquid refrigerant more quickly.

[0062] Therefore, the ice maker 100 provided by the present application can be designed with a smaller condenser 30, and the shorter condensing tube 301 and smaller heat dissipating fins 302 can also condense the refrigerant quickly, thereby realizing a small-volume and efficient condenser 30 design.

[0063] like Figures 3 to 5 As shown, in some embodiments, the inner container 10 is provided with an air hole 11 communicating with the conduit 41 , and the ice maker 100 further includes a switch mechanism disposed at the air hole 11 and capable of opening and closing the air hole 11 .

[0064] In this embodiment, when the ice maker 100 starts to make ice, the compressor of the ice maker 100 starts to work, and after the driving device of the inner tank 10 receives the ice making signal, the cover plate 12 arranged on the inner tank 10 opens the air hole 11 of the inner tank 10, and the low-temperature gas in the inner tank 10 can be blown to the condenser 30 through the air hole 11 and the conduit 41 in turn, so that the temperature of the condensation tube 301 and the heat dissipation fin 302 of the condenser 30 is rapidly reduced. When the ice maker 100 completes ice making or shuts down, the controller of the ice maker 100 sends a signal, the driving device starts, and drives the gear to drive the cover plate 12 to move to the position of closing the air hole 11 of the inner tank 10, thereby achieving the purpose of maintaining the temperature of the inner tank 10 at a low temperature.

[0065] like Figure 1 and Figure 2As shown, in an optional embodiment, the switch mechanism includes a driving device and a cover plate 12 , and the driving device is configured to be connected to the cover plate 12 to drive the cover plate 12 to cover the air hole 11 or open the air hole 11 .

[0066] In this embodiment, when the ice maker 100 starts to make ice, the compressor of the ice maker 100 starts to work, and after the driving device of the inner tank 10 receives the ice making signal, the cover plate 12 arranged on the inner tank 10 opens the air hole 11 of the inner tank 10, and the low-temperature gas in the inner tank 10 can be blown to the condenser 30 through the air hole 11 and the conduit 41 in turn, so that the temperature of the condensation tube 301 and the heat dissipation fin 302 of the condenser 30 is rapidly reduced. When the ice maker 100 completes ice making or shuts down, the controller of the ice maker 100 sends a signal, the driving device starts, and drives the gear to drive the cover plate 12 to move to the position of closing the air hole 11 of the inner tank 10, thereby achieving the purpose of maintaining the temperature of the inner tank 10 at a low temperature.

[0067] Specifically, the driving device includes a driving motor, which is connected to the cover plate 12 via a gear train. The driving motor drives the cover plate 12 to open and close the air holes 11 on the inner container 10 via the gear train.

[0068] like Figures 1 to 7 As shown, the ice maker 100 provided in the embodiment of the present application mainly includes an inner tank 10, a conduit 41, a condenser 30, a first heat sink 421, a second heat sink 422, a bracket 31, a fan 32, a cover plate 12, a driving device and other parts. The inner tank 10 is provided with a cover plate 12, a driving device and other parts. The side wall of the inner tank 10 is provided with an air hole 11 connected to the conduit 41, the air hole 11 is connected to one end of the conduit 41, and the other end of the conduit 41 is connected to the first air inlet of the first heat sink 421. The first heat sink 421 is configured as a semi-frame heat sink in a concave state, and the three surfaces of the semi-frame heat sink are tightly matched with the second heat sink 422. A plurality of first air outlet holes are evenly distributed on the three surfaces of the semi-frame heat sink, and the second heat sink 422 is configured as a full-frame heat sink, and a plurality of heat dissipation holes 423 are evenly distributed around the second heat sink 422.

[0069] A bracket 31 is installed on the side of the condenser 30 facing away from the heat dissipation frame assembly 42. The bracket 31 is connected to the fan 32 of the ice maker 100. When the fan 32 is working, it can suck the low-temperature gas in the inner tank 10 and blow it toward the condenser 30. The low-temperature gas causes the surface temperature of the condenser tube 301 and the heat dissipation fins 302 of the condenser 30 to drop rapidly, so that the refrigerant in the condenser tube 301 can be condensed and converted into liquid refrigerant more quickly.

[0070] When the ice maker 100 starts ice making, the compressor of the ice maker 100 starts working. After the driving device of the inner tank 10 receives the ice making signal, the cover plate 12 arranged on the inner tank 10 opens the air hole 11 of the inner tank 10. The low-temperature gas in the inner tank 10 can be blown toward the condenser 30 through the air hole 11 and the conduit 41 in turn, so that the temperature of the condensing tube 301 and the heat dissipation fins 302 of the condenser 30 is rapidly reduced, so that the temperature of the refrigerant passing through the condensing tube 301 is reduced, so that the refrigerant in the condensing tube 301 can be condensed and converted into liquid refrigerant more quickly. Therefore, the ice maker 100 provided in the implementation of the present application can be designed with a smaller condenser 30, and the shorter condensing tube 301 and the smaller heat dissipation fins 302 can also quickly condense the refrigerant, thereby realizing a small-volume and efficient condenser 30 design. When the ice maker 100 finishes making ice or shuts down, the controller of the ice maker 100 sends a signal, the driving device starts, and drives the gear to drive the cover plate 12 to move to a position to close the air hole 11 of the inner tank 10, thereby achieving the purpose of maintaining the temperature of the inner tank 10 at a low temperature.

[0071] like Figures 1 to 8 As shown, the second aspect of the present application provides a control method for an ice maker 100, and the control method is implemented by the ice maker 100 of the first aspect of the present application, and the control method includes: obtaining the state of the ice maker 100; according to the ice maker 100 being in an ice-making condition, controlling the driving device to drive the cover plate 12 to open the air hole 11; according to the ice maker 100 being in a heat preservation condition or a shutdown condition, controlling the driving device to drive the cover plate 12 to close the air hole 11.

[0072] In the present embodiment, the ice maker 100 of the present application embodiment proposes to dissipate heat for the condenser 30 through the cold air of the inner tank 10, which effectively solves the problem that the condenser 30 of the ice maker 100 is too large, thereby reducing the overall size and volume of the ice maker 100, reducing the overall cost of the ice maker 100, and improving the market competitiveness of the ice maker 100; at the same time, dissipating heat for the condenser 30 through the cold air of the inner tank 10 can improve the ice making performance, energy efficiency ratio and service life of the ice maker 100.

[0073] Specifically, when the ice maker 100 starts the ice making operation, the compressor of the ice maker 100 starts working. After the driving device of the inner tank 10 receives the ice making signal, the cover plate 12 arranged on the inner tank 10 opens the air hole 11 of the inner tank 10. The low-temperature gas in the inner tank 10 can be blown toward the condenser 30 through the air hole 11 and the conduit 41 in turn, so that the temperature of the condensing tube 301 and the heat dissipation fins 302 of the condenser 30 is rapidly reduced, so that the temperature of the refrigerant passing through the condensing tube 301 is reduced, so that the refrigerant in the condensing tube 301 can be condensed and converted into liquid refrigerant more quickly. Therefore, the ice maker 100 provided in the implementation of the present application can be designed with a smaller condenser 30, and the shorter condensing tube 301 and the smaller heat dissipation fins 302 can also quickly condense the refrigerant, thereby realizing a small-volume and efficient condenser 30 design. When the ice maker 100 finishes making ice or shuts down, the controller of the ice maker 100 sends a signal, the driving device starts, and drives the gear to drive the cover plate 12 to move to a position to close the air hole 11 of the inner tank 10, thereby achieving the purpose of maintaining the temperature of the inner tank 10 at a low temperature.

[0074] like Figures 1 to 8 As shown, in some embodiments, according to the ice maker 100 being in the ice making condition, controlling the driving device to drive the cover 12 to open the air hole 11 specifically includes: obtaining the refrigeration temperature of the refrigeration chamber and the ambient temperature of the condenser 30; and controlling the opening size of the air hole 11 according to the refrigeration temperature and the ambient temperature.

[0075] In the above embodiment, the low-temperature gas in the inner tank 10 can be blown to the condenser 30 through the conduit 41. In order to reduce the insufficient cooling capacity of the inner tank 10 or the ice-making failure phenomenon, the embodiment of the present application proposes to accurately control the size of the air hole 11 and the loss of cold air, so that the ice maker 100 can continuously make ice at a low temperature in the inner tank 10 during the ice-making process. The cooling capacity during ice-making can ensure the low temperature of the cavity of the inner tank 10.

[0076] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations are all within the scope defined by the present application.
