Description

Technical Field

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

[0002] Existing ice-making mechanisms typically use ice molds to make ice. The ice-making component is located on one side of the ice mold. When the ice mold is closed, an ice-making cavity is formed inside. The ice-making component exchanges heat with the water in the ice-making cavity to make the water freeze into ice, thus achieving ice making. During the freezing process, the volume of the contents of the ice-making cavity expands, which can easily cause the ice mold to burst, resulting in damage to the ice mold and making the ice blocks easily deformable.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] This invention addresses the problem mentioned above where the volume of the contents of the ice cavity expands during the freezing process, easily causing the ice mold to burst and resulting in damage to the ice mold and deformation of the ice. It proposes an ice-making mechanism and ice maker.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An ice-making mechanism includes an ice-making mold, which comprises a first mold shell and a second mold shell. The first mold shell has at least one first forming cavity, and the second mold shell has at least one second forming cavity. The first forming cavity and the second forming cavity are correspondingly arranged. The ice-making mold has a mold-closed state and an ice-removed state, respectively corresponding to the first mold shell and the second mold shell being in contact and separated. When the ice-making mold is in the mold-closed state, an ice-making cavity is formed through the first forming cavity and the second forming cavity. The ice-making cavity is connected to a liquid inlet channel for injecting liquid into the ice-making cavity. An ice-making component and a pressure relief device are respectively provided on opposite sides of the ice-making mold. The ice-making component condenses the liquid in the ice-making cavity into ice. The pressure relief device is correspondingly arranged to the ice-making cavity, and the pressure relief device has a first pressure relief channel communicating with the ice-making cavity.

[0007] As described above, the ice-making mechanism has a first mounting part on the outer side of the second mold shell for mounting the pressure relief device. The pressure relief device is connected to the first mounting part, and a sealing element is provided between the pressure relief device and the first mounting part.

[0008] As described above, the first mounting part includes a pressure relief port communicating with the second forming cavity and the first pressure relief channel, and a sleeve disposed outside the pressure relief port. The sleeve encloses and forms a mounting cavity adapted to the pressure relief device, and the sealing element is disposed between the sleeve and the pressure relief device.

[0009] As described above, the ice-making mechanism further includes a fixed outer shell on the outside of the second mold shell. The fixed outer shell is provided with a second mounting part, which includes a first receiving cavity for accommodating the sleeve, a second receiving cavity for accommodating the pressure relief device, and a through hole communicating with the pressure relief channel.

[0010] In the ice-making mechanism described above, the fixed outer shell is detachably connected to the second mold shell.

[0011] As described above, the ice-making mechanism has a heating device on the outside of the ice-making mold, which heats the ice-making mold.

[0012] As described above, the ice-making mechanism includes a first heating element disposed on the outside of the first mold shell and a second heating element disposed on the outside of the second mold shell, both of which are provided with electrical terminals.

[0013] As described above, the ice-making mechanism further includes a second pressure relief channel communicating with the ice-making cavity between the first mold shell and the second mold shell.

[0014] As described above, the ice-making mechanism includes an inner mold shell and an outer mold shell. The second forming cavity and the second pressure relief channel are disposed in the inner mold shell. A positioning protrusion is also provided between the outer mold shell and the inner mold shell. The first pressure relief channel extends to the inner side of the positioning protrusion.

[0015] This utility model also provides an ice maker, including the ice-making mechanism described above.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In the ice-making mechanism of this utility model, the ice-making component and the pressure relief device are arranged opposite each other on both sides of the ice-making mold. The ice-making component condenses the liquid in the ice-making cavity into ice, and the pressure relief device is arranged correspondingly to the ice-making cavity, and the pressure relief device has a first pressure relief channel communicating with the ice-making cavity. During the freezing process, the ice-making component forms an ice-forming direction in the ice-making cavity from the ice-making component towards the pressure relief device. As the liquid in the ice-making cavity freezes layer by layer along this ice-forming direction, the excess liquid in the ice-making cavity is directly discharged to the outside of the ice-making mold through the pressure relief device, so as to reduce the pressure accumulation inside the ice-making cavity, prevent the ice-making mold from being stretched open, thereby achieving the purpose of protecting the ice-making mold, preventing the ice block from deforming during the freezing process, ensuring the smooth formation of the ice block, and improving the quality of the ice block.

[0029] Example 1:

[0030] like Figure 1 As shown in Figure 7, Figure 5 The arrow direction indicates the direction of liquid discharge when the first pressure relief channel 140 is depressurized; this utility model provides an ice-making mechanism and an ice maker. The ice maker includes an ice-making mechanism, which includes an ice-making mold 1, an ice-making component 2, and a pressure relief device 14. The ice-making mold 1 includes a first mold shell 11 and a second mold shell 12. The first mold shell 11 is provided with at least one first forming cavity 101, and the second mold shell 12 is provided with at least one second forming cavity 102. The first forming cavity 101 and the second forming cavity 102 are correspondingly arranged. The ice-making mold 1 has a mold-closed state and an ice-removed state corresponding to the first mold shell 11 and the second mold shell 12 being in contact and separated, respectively. When the ice-making mold 1 is in the mold-closed state, an ice-making cavity 10 is formed through the first forming cavity 101 and the second forming cavity 102. The ice-making cavity 10 is connected to a liquid inlet channel 13, which is used to supply liquid to... The ice-making chamber 10 is filled with liquid. The ice-making assembly 2 and the pressure relief device 14 are positioned opposite each other on both sides of the ice-making mold 1. The ice-making assembly 2 freezes the liquid in the ice-making chamber 10 into ice. The pressure relief device 14 is correspondingly arranged with the ice-making chamber 10 and has a first pressure relief channel 140 communicating with the ice-making chamber 10. During the freezing process, the ice-making assembly 2 forms an ice-forming direction in the ice-making chamber 10 from the ice-making assembly 2 toward the pressure relief device 14. As the liquid in the ice-making chamber 10 freezes layer by layer along the ice-forming direction, excess liquid in the ice-making chamber 10 is directly discharged to the outside of the ice-making mold 1 through the pressure relief device 14 to reduce the pressure accumulation inside the ice-making chamber 10, prevent the ice-making mold 1 from being stretched open, thereby protecting the ice-making mold 1, preventing the ice from deforming during the freezing process, ensuring the smooth formation of the ice, and improving the quality of the ice.

[0031] Optionally, one or more of the first forming cavity 101 and the second forming cavity 102 are correspondingly provided, and one or more ice-making cavities 10 can be formed when the ice-making mold 1 is closed.

The specific layout design of each first forming cavity 101 and each second forming cavity 102 can be set according to the size of the ice-making mold 1 or the number of ice-making requirements. By increasing the number of the first forming cavities 101 and the second forming cavities 102, it is beneficial to increase the ice output of the ice-making mechanism and improve the ice supply efficiency of the ice-making mechanism.

The liquid inlet channel 13 and the first pressure relief channel 140 are on the same straight line. By arranging the pressure relief device 14 opposite to the ice-making assembly 2 in the freezing direction, the uniformity of pressure relief within the ice-making cavity 10 is improved, thereby further improving the quality of the ice. Preferably, the pressure relief device 14 is located in the middle of the outside of the second mold shell 12.

[0035] like Figure 2 As shown in Figure 4, the outer side of the second mold shell 12 is provided with a first mounting part 111 for mounting the pressure relief device 14.

The first mounting holes 162 and the second mounting holes 105 correspond one-to-one, and fasteners are inserted between the first mounting holes 162 and the second mounting holes 105 to achieve the detachable installation of the fixed outer shell 16. The fasteners include one of screws, bolts, and pins.

[0041] On the other hand, such as Figure 2 As shown in Figure 6, a heating device 3 is provided on the outside of the ice-making mold 1 to heat the ice-making mold 1; after ice making is completed, the first mold shell 11 and the second mold shell 12 separate to switch the ice-making mold 1 to the position shown in Figure 6. Figure 6 The de-icing state shown allows the ice cubes to fall out naturally. Before switching to the de-icing state, the ice mold 1 can be heated by the heating device 3 to slightly melt the ice cubes and allow them to detach from the mold 1, preventing them from sticking inside and falling out. It should be noted that... Figure 6 This is a schematic diagram of the de-icing state of one embodiment of the ice-making mold 1 of this utility model, and does not limit the specific de-icing form and structure of the ice-making mold 1.

[0042] Further optional, such as Figure 2 and Figure 3As shown, the heating device 3 includes a first heating element 31 disposed on the outside of the first mold shell 11 and a second heating element 32 disposed on the outside of the second mold shell 12. Both the first heating element 31 and the second heating element 32 are provided with an electrical terminal 33 for receiving electricity to power the heating elements.

Between the first mold shell 11 and the fixed outer shell 16, the second heating element 32 is disposed between the second mold shell 12 and the fixed outer shell 16, and the fixed outer shell 16 has an opening 163 corresponding to the power receiving end 33 of the second heating element 32 to facilitate power connection of the power receiving end 33 of the second heating element 32; both the first mold shell 11 and the second mold shell 12 have mounting grooves 1221 on their outer sides for mounting the heating element to reduce the volume of the ice-making mechanism; or, the first mold shell 11 has a back plate 112, the first heating element 31 is embedded in the back plate 112, and the power receiving end 33 of the first heating element 31 protrudes from the back plate 112 to facilitate power connection. It should be noted that the mounting groove in the first mold shell 11 is not shown in the figure.

[0043] Furthermore, both the first heating element 31 and the second heating element 32 cover the ice-making cavity 10, and both the first heating element 31 and the second heating element 32 are provided with assembly clearance openings 34 corresponding to the ice-making cavity 10. The assembly clearance opening 34 of the first heating element 31 is used for the liquid inlet channel 13 to pass through, and the assembly clearance opening 34 of the second heating element 32 is used for the sleeve 1112 to pass through, so as to increase the heating area and improve the de-icing efficiency.

[0044] In other alternative embodiments, such as Figure 7 As shown, a second pressure relief channel 17 communicating with the ice-making cavity 10 is also provided between the first mold shell 11 and the second mold shell 12; specifically, the first mold shell 11 has a first parting surface 103, and the second mold shell 12 has a second parting surface 104. When the first parting surface 103 and the second parting surface 104 are tightly fitted, the first mold shell 11 and the second mold shell 12 are in the following position: Figure 1The molded state shown allows the first molding cavity 101 and the second molding cavity 102 to combine to form a complete ice-making cavity 10. Complete ice blocks can be produced within the ice-making cavity 10 using the ice-making assembly 2. A second pressure relief channel 17 is formed by the recesses of the parting surface of the first mold shell 11 and / or the parting surface of the second mold shell 12. The outlet of the second pressure relief channel 17 is located at the top and / or the bottom of the ice-making mold 1. During the freezing process, excess liquid and gas in the ice-making cavity 10 can be further discharged through the second pressure relief channel 17, improving the pressure relief effect and further enhancing the quality of the ice blocks.

[0045] In some alternative embodiments, when the first molding cavity 101 and the second molding cavity 102 are respectively provided with a plurality of such cavities, for example Figure 7 As shown, the second pressure relief channel 17 includes a first branch 171 corresponding to the ice-making cavity 10 and a second branch 172 communicating with the first branch 171. Each first branch 171 is located on one side of the corresponding molding cavity, and the second branch 172 is independently located on one side of any second molding cavity 102. At least one second branch 172 is provided, and the second branch 172 is formed by the convergence of two or more first branches 171. Furthermore, the outlet of the second branch 172 is located at the top and / or the bottom of the ice-making mold 1, so as to simplify the layout design of the second pressure relief channel 17 and reduce the manufacturing difficulty of the second mold shell 12.

[0046] On the other hand, the ice-making mechanism also includes a driving device 5 for switching the ice-making mold 1 between a mold-closing state and an ice-removing state. The driving device 5 drives the first mold shell 11 and the second mold shell 12 to move closer to or further away from each other, so that the ice-making mold 1 switches between a mold-closing state and an ice-removing state. Optionally, the driving device 5 may be configured as a device for driving the first mold shell 11 and the second mold shell 12 to rotate relative to each other, or as a device for driving the first mold shell 11 and the second mold shell 12 to move linearly relative to each other.

[0047] Example 2:

[0048] The difference between this embodiment 2 and the above embodiment 1 is that, Figure 2As shown in Figure 5, the second mold shell 12 includes an inner mold shell 121 and an outer mold shell 122. The inner mold shell 121 and the outer mold shell 122 are tightly fixedly connected. The second molding cavity 102 and the second pressure relief channel 17 are disposed in the inner mold shell 121. The first mounting part 111 is disposed on the outside of the outer mold shell 122. Since the structure of the second pressure relief channel 17 is relatively complex, in order to reduce the manufacturing difficulty of the second mold shell 12, the second mold shell 12 is split into the inner mold shell 121 and the outer mold shell 122, and the inner mold shell 121 and the outer mold shell 122 are processed separately, which helps to reduce the processing cost of the ice-making mold 1.

[0049] Furthermore, a positioning protrusion 123 is provided between the outer mold shell 122 and the inner mold shell 121, and the first pressure relief channel 140 extends to the inner side of the positioning protrusion 123; optionally, the positioning protrusion 123 is provided in the outer mold shell 122 or the inner mold shell 121; for example, the positioning protrusion 123 penetrates the outer mold shell 122, the pressure relief port 1111 is provided inside the positioning protrusion 123, and the positioning protrusion 123 has an extension 1231 on the side facing the inner mold shell 121, and the inner mold shell 121... An assembly port 1211 corresponding to the extension 1231 is provided. The inner mold shell 121 and the outer mold shell 122 are fixedly connected by the engagement of the extension 1231 and the assembly port 1211, so as to enhance the tightness of the connection between the inner mold and the outer mold shell 122. The height of the extension 1231 is equal to the thickness of the inner mold shell 121, preventing the extension 1231 from extending into the second molding cavity 102, so that the inner wall of the inner mold shell 121 remains smooth and flat, thereby improving the quality of the ice.
