[0028] 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 within the scope of protection of the present invention.

[0029] 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.

[0030] 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.

[0031] The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms 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 horizontal, and the direction perpendicular to the ground is vertical; the side close to the user is the front side, and the side away from the user is the rear side.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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.

[0033] refer to Figures 1 to 12 As shown, the utility model provides an ice-making assembly, which uses manual methods to perform water injection, ice removal and ice taking operations, and can be arranged in the freezing tank of the refrigeration equipment to improve the space utilization rate of the freezing tank. Similarly, the ice-making assembly can also be arranged in a separate ice-making room.

[0034] Specifically, Figures 1 to 5 As shown, the preferred first embodiment of the utility model provides an ice-making assembly, including 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.

[0035] Mate Reference Figure 2 As shown, specifically, the ice-making box body 10 includes a base box 11 and an upper cover 12 that cooperate with each other, and an ice storage box 13 that cooperates with the base box 11. In this embodiment, the ice-making mechanism 20 is rotatably matched with the base box 11, and the setting of the upper cover 12 can prevent the ice-making mechanism 20 from being interfered with by the external environment. The base box 11 and the upper cover 12 are surrounded to form an ice-making and ice-storing space to avoid the generation of odor with the interior of the ice-making room. The ice cubes made by the ice-making mechanism 20 will fall into the ice storage box 13 for storage for users to take. Thereby, the functions of water injection, ice making and ice storage are integrated, and the degree of integration of the ice-making component is improved.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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, and more preferably an elastic material, such as silicone. 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, and the two can be fixed together in one piece by secondary injection molding, that is, the two are fixed by encapsulation molding.

[0041] 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, that is, the water injection part 22 is in a water injection state, the water in the water injection chamber 221 flows out directly from the water outlet 222, and does not flow out of the water injection chamber 221 from the water inlet 223, thereby avoiding the situation where water from the ice-making mechanism 20 escapes.

[0042] 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.

[0043] Specifically, the water inlet 27 has a pipe joint 271 forming a water inlet 224. Figure 3 The water inlet 224 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 224 is upward. Thus, the water inlet 224 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 224 when the ice-making part 21 is injected with water.

[0044] 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 in the water injection part 22 at a time or the amount of water injected into the ice tray 211 at a time is just equal to the amount of water required to fill the ice tray 211 with ice, thereby accurately controlling the amount of water injected and achieving quantitative and rapid water injection into the ice tray 211. Therefore, when the water injection chamber 221 is filled with water, the water injection part 22 is used to directly inject water into the ice making part 21, so as to meet the amount of water required for ice making by the ice making part 21, thereby simplifying the ice making process of the ice making assembly.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] Specifically, the water injection portion 22 is preferably integrally formed, that is, the connecting area 223, the pivoting area 225, the pivot shaft 32 and the plug-in block 41 are integrally formed, thereby saving manufacturing costs.

[0053] refer to Figure 6 to Figure 7 As shown, the preferred second embodiment of the utility model provides an ice-making assembly, which, on the basis of 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.

[0054] Specifically, 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 . The ice-making portion 21 abuts against the water injection portion 22 and the fixing portion 24 .

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] refer to Figures 8 to 12 As shown, the preferred third embodiment of the utility model provides an ice-making assembly, which, based on the second embodiment, tilts the inner bottom surface 2211 of the water injection chamber 221 toward the water outlet 222, which is conducive to draining the water in the water injection chamber 221. In this embodiment, the same reference numerals represent the same components with similar functions and are not further described.

[0061] Specifically, the water injection portion 22 has a water injection state. Fig. 9When the water injection part 22 is in the water injection state, the water injection part 22 is placed in the horizontal direction, and the opening of the ice tray 211 is upward. At this time, the water in the water injection cavity 221 can flow into the ice tray 211 through the water outlet 222, thereby forming ice cubes of a specific shape.

[0062] Furthermore, in the water injection state, the level of the bottom surface 2211 of the water injection cavity 221 gradually decreases from the end away from the water outlet 222 toward the end close to the water outlet 222. Fig. 9 The inner bottom surface 2211 of the water injection cavity 221 is inclined in the left-right direction, and the horizontal height of the side close to the water outlet 222 is lower, so that a height difference in the left-right direction is formed in the water injection cavity 221. Therefore, when the water injection part 22 is in the water injection state, the water in the water injection cavity 221 will flow from the end far from the water outlet 222 (for example, the right side) to the end close to the water outlet 222 (for example, the left side), which is conducive to the water in the water injection cavity 221 to be drained.

[0063] The horizontal height of the bottom surface of the water injection chamber 221 gradually decreases from the end far away from the water outlet 222 to the end close to the water outlet 222, which is beneficial for the water in the water injection chamber 221 to flow toward the water outlet 222, so that the water in the water injection chamber 221 can be smoothly discharged from the water outlet 222 without manually adjusting the posture of the water injection part, thereby simplifying the ice making process of the ice maker.

[0064] Specifically, the water injection portion 22 includes a bottom wall 226, and the thickness of the bottom wall 226 gradually decreases from an end away from the water outlet 222 toward an end close to the water outlet 222. Fig. 9 , by setting the bottom wall 226 of the water injection part 22 to have variable wall thickness, that is, different wall thickness in the left and right directions, the inner bottom surface 2211 of the water injection cavity 221 can be tilted in the left and right directions. This method can make the inner bottom surface 2211 of the water injection cavity 221 have a certain slope in the direction toward the water outlet 222 without changing the height difference of the bottom wall 226 itself in the left and right directions or the flatness of the outer contour of the water injection part 22, so as to ensure that water can completely flow out from the water outlet 222, thereby enhancing the drainage effect. Moreover, this method has a simple structure, is easy to implement, and has a relatively low cost.

[0065] Specifically, the water injection portion 22 includes a bottom wall 226, and the height of the bottom wall 226 gradually decreases from an end away from the water outlet 222 toward an end close to the water outlet 222. Fig. 9 By utilizing the height difference of the bottom wall 226 in the left-right direction, the inner bottom surface 2211 of the water injection cavity 221 can be tilted in the left-right direction without changing the wall thickness of the bottom wall 226 .

[0066] Preferably, the two solutions of "setting the bottom wall 226 of the water injection part 22 to have a variable wall thickness" and "the bottom wall 226 itself has a height difference in the left and right directions" are adopted at the same time to ensure that water can completely flow out from the water outlet 222, thereby enhancing the drainage effect.

[0067] Specifically, the ice making unit 21 includes at least one ice cube array 210, each of which includes a plurality of ice cubes 211 and a water channel 212 connecting adjacent ice cubes 211. In this embodiment, each of the ice cube arrays 210 includes a plurality of ice cubes 211 arranged in a left-right direction, and a water channel 212 is provided between the adjacent ice cubes 211.

[0068] Furthermore, the water flow area of ​​the water groove 212 on the side close to the water outlet 222 in each ice cube array 210 is smaller than the water flow area of ​​the water groove 212 on the side far from the water outlet 222. In this embodiment, since the ice cube 211 is made of silica gel material, surface tension may cause uneven water distribution in the ice cube 211, and the water flow areas of the multiple water grooves 212 are gradually designed along the left and right directions, so that the water flow area of ​​the water groove 212 far from the water outlet 222 is larger, which is conducive to the water filling of the ice cube 211 on the side far from the water outlet 222.

[0069] When water is injected into the ice cube array 210, water can be transferred between adjacent ice cubes 211 through the water channel 212. The water flow area refers to the cross-sectional area of ​​water flow transferred between adjacent ice cubes 211. The factors affecting the water flow area may be the width of the water channel 212 in the front-to-back direction and / or the depth of the water channel 212 in the top-to-bottom direction.

[0070] Mate Reference Fig.10 As shown, the volume of the ice cube 211 on the side close to the water outlet 222 in each ice cube array 210 is greater than the volume of the ice cube 211 on the side far from the water outlet 222. In this embodiment, when the ice cube array 210 is filled with water, since the ice cube 211 closer to the water outlet 222 starts to be filled with water before the ice cubes 211 at other positions, and the amount of water required for the ice cube 211 farther from the water outlet 222 is less than the ice cubes 211 at other positions, the volume of multiple ice cubes 211 in the same ice cube array 210 is gradually changed along the left and right directions, so that the ice cubes 211 closer to the water outlet 222 and the ice cubes 211 farther from the water outlet 222 can be filled with water synchronously, ensuring that all ice cubes 211 are filled with water after all the water in the water injection chamber 211 flows out.

[0071] Preferably, the two schemes of "the water flow areas of the multiple water troughs 212 are gradually changed along the left and right direction" and "the volumes of the multiple ice trays 211 are gradually changed along the left and right direction" are adopted at the same time to ensure that all ice trays 211 are filled with water after all the water in the water injection chamber 211 flows out.

[0072] Furthermore, the ice-making mechanism 20 further includes a water inlet 27, a first mounting structure 28 for positioning the water injection part 22 and the water inlet 27, and a second mounting structure 29 for engaging the water injection part 22 and the water inlet 27. In this embodiment, the water injection part 22 and the water inlet 27 are positioned and plugged together by the first mounting structure 28, so as to facilitate mutual positioning and docking between the two. The water injection part 22 and the water inlet 27 are engaged and fixed by the second mounting structure 29, so as to limit the relative displacement between the two.

[0073] Furthermore, the first mounting structure 28 and the second mounting structure 29 are disposed opposite to each other on both sides of the water inlet 27. Fig.10 Preferably, the first mounting structure 28 and the second mounting structure 29 are relatively arranged on the upper and lower sides of the water inlet 27, that is, arranged on the upper and lower sides of the pipe joint 271. Considering that the user needs to clean the water injection cavity 221 by disassembling the pipe joint 271, the first mounting structure 28 and the second mounting structure 29 use different structures to achieve different functions, which can prevent the reverse installation when the water injection part 22 and the water inlet 27 are connected, and prevent water from flowing out of the water inlet 224 when the reverse installation occurs.

[0074] Specifically, the first mounting structure 28 includes a positioning protrusion arranged on the water injection part 22 and a positioning groove arranged on the water inlet part 27, and the second mounting structure 29 includes a snap-in protrusion arranged on the water injection part 22 and a snap-in opening arranged on the water inlet part 27. After the water injection part 22 and the water inlet part 27 are installed, the positioning protrusion extends into the positioning groove, and the snap-in protrusion abuts against the snap-in opening.

[0075] Specifically, the water inlet 27 includes a water inlet 224 connected to the water injection chamber 221 and a pipe joint 271 forming the water inlet 224, the water injection portion 22 includes a butt joint 227 matching the pipe joint 271, and the ice making mechanism 20 also includes a seal 60. In this embodiment, the radial dimensions of the pipe joint 271 and the butt joint 227 match each other, so as to achieve mutual plug-in cooperation. The seal 60 is configured as a sealing ring, which can seal the butt joint between the pipe joint 271 and the butt joint 227 to prevent the water flow in the water injection chamber 221 from leaking from the butt joint between the pipe joint 271 and the butt joint 227.

[0076] Further, the sealing member 60 is sleeved on one of the pipe joint 271 and the butt joint 227, and abuts on the other of the pipe joint 271 and the butt joint 227. In this embodiment, it is preferred that the sealing member 60 is sleeved on the pipe joint 271 and abuts on the inner wall of the butt joint 227. The user can clean the water injection cavity 221 by disassembling the pipe joint 271, so that the sealing member 60 sleeved on the pipe joint 271 can be replaced.

[0077] Furthermore, the water injection part 22 includes a lower shell 228 and an upper shell 229 forming a bottom wall 226. In this embodiment, the water injection part 22 is designed in a split body, that is, it is composed of a lower shell 228 and an upper shell 229 connected to each other, which is convenient for cleaning and maintenance of the water injection cavity 221 and is also beneficial for manufacturing the water injection part 22.

[0078] Furthermore, the lower shell 228 and the upper shell 229 are welded to each other. In this embodiment, the lower shell 228 and the upper shell 229 can be welded and fixed by hot plate welding, ultrasonic welding, etc. Fig.11 Corresponding first step surfaces 2281 and second step surfaces 2291 may also be provided on the lower shell 228 and the upper shell 229, respectively. By utilizing the mutual positioning between the first step surfaces 2281 and the second step surfaces 2291, the positioning and matching between the lower shell 228 and the upper shell 229 can be achieved, thereby facilitating welding between the lower shell 228 and the upper shell 229.

[0079] Mate Reference Fig.12 As shown, further, the ice making box body 10 includes a bottom box 11, an upper cover 12 and an ice-removing member 14 connected to the upper cover 12. In this embodiment, the number of the ice-removing members 14 corresponds to the number of the ice trays 211.

[0080] Specifically, the water injection portion 22 has an ice-removing state, and in the ice-removing state, the ice-removing member 14 abuts against the ice tray 211. Fig.12 When the water injection part 22 is in the deicing state, the water injection part 22 is placed in the horizontal direction, and the opening of the ice tray 211 is downward. After ice making is completed, the water injection part 22 is switched from the water injection state to the deicing state by reversing the ice making mechanism 20, and the deicing member 14 is abutted against the ice tray 211 and the upper cover 12 is pressed downward, so that the ice tray 211 can be deiced labor-savingly and quickly.

[0081] According to another aspect of the present invention, a refrigerator is provided, wherein the refrigerator is provided with an ice-making assembly according to the present invention, and the ice-making assembly is preferably arranged in a freezer compartment or an ice-making room. Moreover, the ice-making assembly can be directly placed in the freezer compartment or the ice-making room, or can be detachably connected to a freezer liner.
