[0026] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all included in the protection scope of the present invention.

[0027] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0028] It should be understood that the terms used herein, such as "upper", "lower", "outer", "inner", etc., indicating spatial relative positions are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatial relative position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0029] The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptors used herein shall be interpreted accordingly. For example, in the present invention, for ease of description, when the ice-making assembly is in normal use, the direction toward the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is the horizontal direction, and the direction perpendicular to the ground is the vertical direction; the side close to the user is the front side, and the side away from the user is the rear side.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0031] refer to Figures 1 to 10 As shown, the present invention provides an ice-making assembly, which performs water injection, ice removal and ice retrieval in a manual manner, and can be arranged in a freezing tank of a refrigeration device or in a separate ice-making room.

[0032] Specifically, Figures 1 to 5 As shown, an ice-making assembly provided by a preferred embodiment of the present invention includes an ice-making box body 10 and an ice-making mechanism 20 matched with the ice-making box body 10. In this embodiment, the ice-making mechanism 20 is used to hold liquid to make ice cubes, and is rotatably matched with the ice-making box body 10 to realize rotating ice removal.

[0033] Mate Reference Figure 2 As shown, specifically, the ice-making box body 10 includes a bottom box 11 and an upper cover 12 that cooperate with each other, and an ice storage box 13 that cooperates with the bottom box 11. In this embodiment, the ice-making mechanism 20 is rotatably matched with the bottom box 11, and the arrangement of the upper cover 12 can prevent the ice-making mechanism 20 from being interfered by the external environment. The ice cubes made by the ice-making mechanism 20 will fall into the ice storage box 13 for storage and be taken by the user.

[0034] Specifically, the ice making mechanism 20 includes an ice making part 21 for forming an ice grid 211 and a water injection part 22 for forming a water injection chamber 221. In this embodiment, water is first injected into the water injection chamber 221 of the water injection part 22, and then the water in the water injection chamber 22 is introduced into the ice grid 211 of the ice making part 21, so that ice cubes of a specific shape are formed in the ice grid 211. The ice making part 21 has a plurality of ice grids 211, and the plurality of ice grids 211 are arranged in a matrix.

[0035] Furthermore, the ice making part 21 is connected to the water injection part 22. In this embodiment, the ice making part 21 and the water injection part 22 are fixed together to form a whole body that rotates with the ice making box body 10, so the ice making part 21 and the water injection part 22 always remain relatively still.

[0036] Mate Reference Figure 3 As shown, further, the ice-making mechanism 20 has a water injection space 23 connected to the opening of the ice tray 211, and the water injection portion 22 has a water outlet 222 connected to the water injection chamber 221, and the water outlet 222 is exposed in the water injection space 23. In this embodiment, after the user injects water into the water injection chamber 221, the water in the water injection chamber 221 flows out through the water outlet 222, flows through the water injection space 23, and finally flows into the ice tray 211. When the water flowing out of the water outlet 222 contacts the water in the ice tray 211, even if splashing occurs, it will only fall into the water injection space 23 formed by the ice-making mechanism 20, thereby avoiding falling outside the ice-making box body 10 or avoiding falling into the ice storage box 13, thereby ensuring the normal ice making of the ice-making assembly.

[0037] Moreover, since the ice making part 21 and the water injection part 22 are fixed to each other, the distance between the water outlet 222 and the ice tray 211 remains unchanged, so there is no need to manually adjust the distance between the two to prevent water splashing, which simplifies the ice making process of the ice making assembly.

[0038] Furthermore, the ice-making part 21 is connected to the water injection part 22 by secondary injection molding. In this embodiment, the ice-making part 21 is preferably made of a flexible material, such as silica gel. The water injection part 22 is preferably made of a hard material. Therefore, the ice-making part 21 and the water injection part 22 are made of two materials, so the two can be fixed together in one piece by secondary injection molding, that is, the two are fixed by encapsulation molding.

[0039] Specifically, the ice making part 21 has a docking area 212 connected to the ice tray 211, and the water injection part 22 has a connecting area 223 matching the docking area 212. The ice tray 211, the docking area 212 and the connecting area 223 are arranged in a vertical direction. The water injection space 23 includes a first water injection channel 231 formed by the docking area 212 and a second water injection channel 232 formed by the connecting area 223. The water outlet 222 is exposed in the first water injection channel 231 and / or the second water injection channel 232.

[0040] In this embodiment, the docking area 212 and the connection area 223 both adopt a closed annular structure, thereby forming a first water injection channel 231 and a second water injection channel 232 that are closed in the horizontal direction, so that water flowing out of the water outlet 222 cannot splash out from the first water injection channel 231 and the second water injection channel 232, thereby preventing water droplets from splashing into the ice storage box 13 and causing ice cubes to stick together, and also preventing water droplets from splashing outside the ice making box body 10 after the cover plate 12 is closed.

[0041] Specifically, at least part of the water outlet 222 is exposed in the first water injection channel 231, so that the water outlet 222 is close to the end surface where the ice tray 211 is opened, that is, the maximum water level of the ice tray 211, to minimize the height of the water flow and reduce splashing. The water outlet 222 is preferably exposed in the first water injection channel 231.

[0042] Furthermore, the ice making mechanism 20 has a water inlet 224 exposed toward the water injection chamber 221, and the height of the water inlet 224 exposed in the water injection chamber 221 is greater than the height of the water outlet 222 exposed in the water injection chamber 221. In this embodiment, when water is injected into the water injection portion 22, water flows into the water injection chamber 221 from the water inlet 224. Figure 3 When the ice-making mechanism 20 is placed horizontally, the water inlet 224 is located above the water outlet 222 and opens upward, while the water outlet 222 opens to the right. Therefore, when the water injection part 22 is placed horizontally to inject water into the ice-making part 21, the water in the water injection cavity 221 flows out directly from the water outlet 222, and does not flow out of the water injection cavity 221 from the water inlet 223, thereby avoiding the situation where water flows out of the ice-making mechanism 20.

[0043] Mate Reference Figure 2 and Figure 4 As shown, the ice making mechanism 20 further includes a water inlet 27 connected to the water injection part 22. In this embodiment, the water inlet 27 is sealed and connected to the water injection part 22 by plugging, so as to facilitate cleaning of the water injection cavity 221.

[0044] Specifically, the water inlet 27 has a pipe joint 271 forming a water inlet 224 and a guide plate 272 connected to the pipe joint 271. The water inlet 224 is located on a side of the pipe joint 271 that is away from the water outlet 222 in the vertical direction. Figure 3 The water inlet 222 is preferably disposed on the upper side of the pipe joint 271, that is, when the ice-making mechanism 20 is placed horizontally, the opening of the water inlet 222 is upward. Thus, the water inlet 222 is made higher than or farther away from the water outlet 222 to the greatest extent, so that the water injection part 22 can store enough water when placed horizontally, so that no leakage occurs at the water inlet 222 when the ice-making part 21 is injected with water.

[0045] Moreover, the volume of the water injection chamber 221 can be set according to the number of ice trays 211 and the amount of water stored, that is, the amount of water stored and injected into the ice tray 211 by the water injection unit 22 is exactly equal to the amount of water required to fill the ice tray 211 with ice, thereby accurately controlling the amount of water injected. Therefore, when the water injection chamber 221 is filled with water, the water injection unit 22 is used to directly inject water into the ice making unit 21, which can meet the amount of water required for ice making by the ice making unit 21, thereby simplifying the ice making process of the ice making assembly.

[0046] Furthermore, the pipe joint 271 has a joint opening 2711 communicating with the water inlet 224 , and the distance between the guide plate 272 and the plane where the joint opening 2711 is located gradually decreases from one end of the guide plate 272 close to the water inlet 224 toward the other end of the guide plate 272 away from the water inlet 224 .

[0047] In this embodiment, the pipe joint 271 has a joint channel 2712 connecting the joint port 2711 and the water inlet 224. Figure 4 When the ice-making mechanism 20 is placed vertically, when the external water circuit is connected to the water source through the pipe joint 271, the water flows through the joint channel 2712 to the guide plate 27, and then flows into the water injection chamber 221 from the water inlet 224 after being guided by the guide plate 27. When the ice-making mechanism 20 is placed vertically and water is injected, the guide plate 27 is inclined toward the water inlet 224, which on the one hand allows the water injection chamber 221 to be quickly filled, and on the other hand reduces the splashing of water when the water flows into the water injection chamber 221. In addition, this method can also prevent the water from remaining in the pipe joint 271.

[0048] Continue with reference Figure 3 As shown, the ice-making mechanism 20 also has a water inlet 28 exposed toward the water injection chamber 221 and a water channel 29 connecting the water inlet 28 and the water outlet 222. The water inlet 28 and the water outlet 222 are arranged opposite to each other in the horizontal direction and are located on the side of the water channel 29 close to the water inlet 224.

[0049] In this embodiment, the water guide channel 29 extends in the left-right direction, that is, along the arrangement direction of the single-row ice cube trays 211, and the water guide port 28 and the water outlet 222 are arranged at two ends of the water guide channel 29. The water inlet 224, the water guide port 28 and the water outlet 222 are all located on the same side of the ice making part 21. The arrangement of the water guide port 28 prevents the water in the water injection chamber 221 from flowing out from the water outlet 222 when the ice making mechanism 20 is placed vertically for water injection.

[0050] Mate Reference Figure 1 and Figure 5 As shown, further, the ice-making assembly also includes a pivot structure 30 for rotating the water injection part 22 and the ice-making box body 10, and a docking structure 40 for positioning the water injection part 22 and the ice-making box body 10. In this embodiment, the water injection part 22 and the ice-making box body 10 are pivotally matched by the pivot structure 30, so as to realize rotating de-ice removal. The water injection part 22 and the ice-making box body 10 are mutually limited by the docking structure 40, so as to avoid the deflection or displacement of the ice-making mechanism 20 during ice making and de-ice removal.

[0051] Specifically, the docking structure 40 includes a plug-in block 41 provided on one of the water injection part 22 and the ice-making box body 10, and a plug-in groove 42 provided on the other of the water injection part 22 and the ice-making box body 10. The ice-making mechanism has an ice-making position and an ice-removing position based on the rotational cooperation between the water injection part 22 and the ice-making box body 10. In the ice-making position and the ice-removing position, at least a portion of the plug-in block 41 extends into the plug-in groove 42.

[0052] In this embodiment, two opposite plug blocks 41 are preferably provided on the water injection portion 22, and two plug slots 42 corresponding to the plug blocks 41 are provided on the bottom box 11, so that the ice-making mechanism 20 can be switched between the ice-making position and the ice-removing position by rotating 180°. In addition, when the ice-making mechanism 20 is in the ice-making position and the ice-removing position, the ice-making mechanism 20 is more stably limited on the ice-making box body 10. In addition, the plug block 41 and the plug slot 42 are installed and removed by plugging and unplugging, which is convenient for users to operate.

[0053] Furthermore, the ice-making box body 10 includes a base box 11 forming a plug-in slot 42 and an upper cover 12 cooperating with the base box 11, the water injection portion 22 has a connecting area 223 connected to the plug-in block 41, the pivot structure 30 includes a pivot slot 31 formed on the base box 11 and a pivot shaft 32 connected to the connecting area 223 and abutting against the pivot slot 31, and the upper cover 12 covers the opening of the pivot slot 31.

[0054] In this embodiment, the open pivot groove 31 is provided on the bottom box 11 to facilitate the disassembly and installation of the ice-making mechanism 20 and the ice-making box body 10, thereby facilitating the cleaning of the ice-making mechanism 20 or the vertical addition of water.

[0055] Furthermore, the water injection portion 22 also includes a pivot area 225 forming a pivot axis 32, the water injection chamber 221 is formed inside the connecting area 223 and the pivot area 225, and the ice-making mechanism has a water inlet 224 exposed toward the inside of the pivot area 225, and the water inlet 224 is spaced apart from the inner wall surface of the pivot area 225.

[0056] In this embodiment, Figure 3 and Figure 5 When the ice-making mechanism 20 is turned upside down for ice removal, even if there is water remaining in the water injection chamber 221, the water will flow into the pivoting area 225. However, since there is a certain gap between the water inlet 224 and the inner wall of the pivoting area 225, the water cannot flow out from the water outlet 222 or the water inlet 224.

[0057] refer to Figures 6 to 10 As shown, another preferred embodiment of the present invention provides an ice-making assembly, which, based on the above embodiment, changes the connection mode between the ice-making part 21 and the water-injection part 22, so as to facilitate the later maintenance and replacement of the ice-making mechanism 20, and save the maintenance cost of the ice-making assembly. In this embodiment, the same reference numerals represent the same components with similar functions and are not further described.

[0058] Specific, with reference Figure 8 As shown, the ice making mechanism 20 further includes a water inlet 27 connected to the water injection part 22. In this embodiment, the water inlet 27 is sealed and connected to the water injection part 22 by means of a spiral fit, so as to facilitate cleaning of the water injection cavity 221.

[0059] Specific, with reference Figure 7 and Fig.10 As shown, the ice-making mechanism 20 further includes a fixing portion 24 connected to the water injection portion 22 and a connecting structure 25 for enabling the fixing portion 24 to engage with the water injection portion 22 , and the ice-making portion 21 abuts against the water injection portion 22 and the fixing portion 24 .

[0060] In this embodiment, the fixing part 24 is fixed to the water injection part 22 by a fastener 50, so as to limit the horizontal and vertical displacement of the ice making part 21. The ice making part 21 and the water injection part 22 are fixed to each other by the fixing part 24, so as to realize a detachable connection.

[0061] Specifically, the connection structure 25 includes a clamping groove 251 provided on one of the fixing part 24 and the water injection part 22, and a clamping block 252 provided on the other of the fixing part 24 and the water injection part 22 and matched with the clamping groove 251. Preferably, two opposite clamping grooves 251 are provided on the fixing part 24, and two corresponding clamping blocks 252 are provided on the water injection part 22. The clamping blocks 252 and the clamping grooves 251 that cooperate with each other facilitate rapid positioning and installation. After the fixing part 24 is pressed against the ice-making part 21, the ice-making part 21 is abutted against the water injection part 22, thereby ensuring the sealing between the ice-making part 21 and the water injection part 22.

[0062] Furthermore, the ice-making mechanism 20 also includes a limiting structure 26 for positioning the fixing portion 24 and the ice-making portion 21. In this embodiment, the setting of the limiting structure 26 limits the horizontal displacement of the ice-making portion 21 and also plays a positioning role in the docking of the fixing portion 24 and the ice-making portion 21.

[0063] Furthermore, the limiting structure 26 includes a positioning groove 261 provided on one of the fixing part 24 and the ice-making part 21, and a positioning block 262 provided on the other of the fixing part 24 and the ice-making part 21 and matching with the positioning groove 261. In this embodiment, since the fixing part 24 is made of hard material and the ice-making part 21 is made of flexible material, it is preferred that the positioning block 262 is provided on the fixing part 24 and the positioning groove 261 is provided on the ice-making part 21. Both the positioning block 262 and the positioning groove 261 are provided in an annular shape, surrounding the outer sides of the plurality of ice cube trays 211. After the fixing part 24 and the water injection part 22 are connected to each other, the positioning block 262 is pressed tightly in the positioning groove 261, thereby improving the sealing between the ice-making part 21 and the water injection part 22.

[0064] Specifically, at least a portion of the positioning block 262 extends into the positioning groove 261 and abuts against the inner wall of the positioning groove 261. In this embodiment, the cross-sectional shape of the positioning groove 261 is preferably a trapezoid. After the positioning block 262 is pressed into the positioning groove 261, the positioning block 262 abuts against the groove wall surface of the positioning groove 261 in the horizontal direction and the vertical direction, so that it is not easy to cause horizontal deviation between the ice-making part 21 and the fixing part 24, and the sealing performance between the ice-making part 21 and the water injection part 22 is ensured.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
