Description

Technical Field

[0001] The present application relates to an ice maker, and more particularly to an extrusion ice maker. Background Art

[0002] An ice maker is a refrigeration machine that compresses or expands liquid refrigerant to produce high-temperature and high-pressure gas (steam), causing the liquid to evaporate rapidly.

[0003] Existing household or commercial ice makers usually use compressor-type refrigerators. Existing ice makers mainly include a casing, a refrigeration component, an ice delivery component, and an ice storage bin. After the refrigeration component condenses water into ice, it is transported to the ice storage bin for storage through the ice delivery component. The ice delivery component includes a drive motor, an ice cylinder, and an extruder. The extruder is a screw member that is rotatably arranged in the ice cylinder and is coaxially connected to the drive motor. Water condenses into columnar ice cubes in the ice cylinder and is transported upward along the screw. An output through hole that is connected to the ice cylinder and for the output of ice cubes is opened circumferentially at the top of the extruder. After the ice cubes are output from the output through hole, they abut against the extruder and break. The broken ice cubes are transported to the ice storage bin along the ice guide channel under the push of subsequent ice cubes.

[0004] When ice cubes of the above-mentioned ice maker are output from the output through hole, they are spread outward along the circumferential direction of the axis of the ice cylinder. However, the ice guide channel is connected to the conveying pipe for conveying ice cubes only on the side facing the ice storage shell. Therefore, the ice cubes output from the side of the extruder away from the conveying channel are prone to blockage after being output for a period of time, affecting the conveying efficiency of the ice cubes. Utility Model Content

[0005] In order to improve the efficiency of conveying ice cubes from an extruder to an ice storage bin, the present application provides an extruder-type ice maker.

[0006] The present application provides an extrusion ice maker adopting the following technical solution:

[0007] An extruder-type ice maker comprises an ice-making body, an ice-making assembly and an ice-guiding channel, wherein the ice-making assembly comprises an ice-making cylinder, an output screw rotatably arranged in the ice-making cylinder, a conveying drive member driving the output screw to rotate, and an extruder arranged at the top of the ice-making cylinder, wherein the extruder is provided with output through holes for outputting ice cubes at intervals; the ice-guiding channel has a conveying cavity for conveying ice cubes, wherein the conveying cavity comprises a first cavity corresponding to the extruder and a second cavity for ice cubes to slide down, wherein the first cavity has a crossing gap on a side away from the second cavity for ice cubes to cross over to the top of the extruder.

[0008] By adopting the above technical solution, the ice cubes move upward along the axis through the output screw in the ice making cylinder. After the columnar ice cubes pass through the output through hole and abut against the side wall of the extruder, the output screw continues to rotate, so that the ice cubes are broken and fall on the bottom wall of the first chamber. The side of the first chamber close to the ice storage bin and the two sides of the conveying direction can slide along the second chamber to the ice storage bin under the push of subsequent ice cubes. By setting the climbing gap, the ice cubes on the side of the first chamber far from the ice storage bin can pass through the climbing gap upward to the top of the extruder and slide to the ice storage bin under the push of the subsequent ice cubes, so that the probability of ice cubes being blocked on the side of the first chamber far from the ice storage bin is reduced, and the overall output efficiency of ice cubes is improved.

[0009] Optionally, the overturning gap extends to an end of the second chamber in a direction away from the extruder.

[0010] By adopting the above technical solution, the extension length of the crossing gap is disclosed, so that there is enough space between the ice guide channel and the ice storage bin for ice cubes to be transported and slide down.

[0011] Optionally, the top wall of the first chamber has a guiding arc surface for guiding ice cubes to the crossing gap.

[0012] By adopting the above technical solution and setting the guide arc surface, the process of ice cubes moving upward to the top of the extruder is smoother, thereby further improving the conveying efficiency of ice cubes.

[0013] Optionally, the ice guide channel includes an ice guide conveying plate fixedly mounted on the extruder and an ice guide cover plate for covering the ice guide plate, the ice guide conveying plate is provided with a first positioning component for positioning installation, and the ice guide cover plate is provided with a second positioning component for positioning installation.

The structure of the ice guide channel is simple and easy to assemble by installers.

[0015] Optionally, the first positioning assembly includes a first positioning plate arranged on both side walls of the ice guide and conveying plate in the length direction, a positioning column for abutting the outer side of the extruder, and a positioning sleeve for sleeve-engaging with the extruder, and the ice-making body has a positioning flat plate for the first positioning plate to position and abut.

[0016] By adopting the above technical scheme, the composition of the first positioning assembly is specifically disclosed, the positioning of the ice guide and conveying plate on the ice-making body is achieved through the first positioning plate, and the positioning and installation of the ice guide and conveying plate and the extruder are achieved through the positioning sleeve and the positioning column. The above-mentioned first positioning assembly facilitates the installer to fix the ice guide and conveying plate.

[0017] Optionally, the inner wall of the positioning sleeve is provided with a sealing ring abutting against the extruder.

[0018] By adopting the above technical solution and setting the sealing ring, the sealing effect of the extruder and the inner cavity of the ice making cylinder is achieved, the probability of external impurities entering the ice making cylinder is reduced, and the probability of water leakage in the ice making cylinder is reduced.

[0019] Optionally, the second positioning assembly includes a plurality of second positioning plates arranged on the outer wall of the ice guide cover plate, some of the second positioning plates are fixedly connected to the positioning flat plate, and another part of the second positioning plates are fixed to the ice guide conveying plate, the ice guide conveying plate has a positioning flange for the second positioning plates to abut against, and the positioning flat plate also has a positioning slot for the ice guide conveying plate to be inserted into.

[0020] By adopting the above technical solution, the composition of the second positioning assembly is specifically disclosed, and the ice guide cover plate is fixed on the positioning flat plate and the ice guide conveying plate through the second positioning plate. At the same time, the positioning slot can improve the stability of the positioning installation of the ice guide cover plate.

[0021] Optionally, the extruder is provided with an isolating ring for rotatably mounting the end of the output screw.

[0022] By adopting the above technical solution and setting the isolating ring, the extruder and the output screw are separated, and direct contact with the extruder can be avoided when the output screw rotates, thereby reducing the generation of noise.

[0023] Optionally, a sealing assembly is provided between the ice-making cylinder and the conveying motor, and the sealing assembly includes a dynamic ring fixed to the bottom of the ice-making cylinder, a static ring sleeved on the output screw, and an elastic member connecting the dynamic ring and the static ring.

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses an extrusion type ice maker.

[0037] Reference Figure 1 and Figure 2An extruder type ice maker includes an ice making body 1, an ice making assembly 2 and an ice guide channel 3. The ice making assembly 2 includes an ice making cylinder 21 vertically installed in the ice making body 1, an output screw 22 rotatably arranged in the ice making cylinder 21, a conveying motor 23 driving the output screw 22 to rotate, and an extruder 24 arranged at the top of the ice making cylinder 21.

[0038] Reference Figure 2 and Figure 3 The conveying motor 23 is fixedly installed at the bottom of the ice-making cylinder 21 and is fixedly connected with the ice-making cylinder 21 by bolts. The output shaft of the conveying motor 23 is coaxially connected with the output screw 22. The extruder 24 includes a connecting plate 241 fixed with bolts to the ice-making cylinder 21 and an extrusion body 242 for outputting ice cubes. The extrusion body 242 has an output through hole 2421 connected to the ice-making cylinder 21 and for outputting ice cubes. The output through holes 2421 are evenly arranged at circumferential intervals. The inner diameter of the output through hole 2421 tends to gradually expand from the bottom to the top to facilitate the output of ice cubes. The top of the extrusion body 242 has an abutment cone 2422 for the output of ice cubes to abut, and the ice cubes abut on the abutment cone 2422 to be bent and broken.

[0039] The bottom of the connecting plate 241 has a mounting hole 2411 for rotatably mounting the end of the output screw 22. The connecting plate 241 is provided with an isolation ring 2412 on the inner wall of the mounting hole 2411. The isolation ring 2412 of this embodiment is made of POM material and is used to space the output screw 22 and the extruder 24 so as to reduce the noise caused by the rotation of the output screw 22.

[0040] The ice-making body 1 transports water into the ice-making cylinder 21 and refrigerates the water in the ice-making cylinder 21 at the same time. The ice cubes in the ice-making cylinder 21 are transported upward to the top of the ice-making cylinder 21 under the action of the output screw 22. After the ice cubes pass through the output through hole 2421, they are transported to the ice storage bin 4 for storing ice cubes under the guidance of the ice guide channel 3.

[0041] The ice guide channel 3 has a conveying chamber 31 connected to the extruder 24 and the ice storage bin 4. The conveying chamber 31 includes a first chamber 311 corresponding to the extruder 24 and a second chamber 312 for guiding the conveying of ice cubes. After the ice cubes are output from the output through hole 2421 and abut against the abutting conical surface 2422, the ice cubes are bent and broken and fall into the first chamber 311. As subsequent ice cubes are generated in the first chamber 311, the originally broken ice cubes can be pushed toward the second chamber 312. The second chamber 312 has a conveying inclined surface 3121 arranged obliquely toward the ice storage bin 4.

[0042] The first chamber 311 has a climbing gap 3111 on a side away from the second chamber 312 for ice cubes to climb over to the top of the squeezer 24. The height of the climbing gap 3111 in the height direction is greater than the inner diameter of the conveying through hole, and the climbing gap 3111 extends in the horizontal direction to an end of the second chamber 312 away from the first chamber 311, that is, corresponding to the ice storage bin 4.

[0043] The inner top wall of the second chamber 312 is provided with a guide arc surface 3112 for ice cubes to climb over. The guide arc surface 3112 guides the ice cubes to the top of the extruder 24, and the ice cubes at the top of the extruder 24 are directly moved to the conveying inclined surface 3121 under the push of subsequent ice cubes.

[0044] The second chamber 312 is provided with an infrared sensor 5 for monitoring the sliding of ice cubes on the side away from the extruder 24. When the ice cubes are transported from the second chamber 312 to the ice storage bin 4, the ice cubes block the light emitted by the infrared sensor 5, and the infrared sensor 5 detects the sliding of ice cubes. The sensor is used to monitor whether the ice making function is normal.

[0045] Reference Figure 2 and Figure 4 The ice guide channel 3 includes an ice guide conveying plate 32 and an ice guide cover plate 33. The ice guide conveying plate 32 and the ice guide cover plate 33 form a conveying cavity 31 that communicates with the extruder 24 and the ice storage bin 4. The ice guide conveying plate 32 has a first positioning component for achieving fixed installation. The ice guide cover plate 33 has a second positioning component for achieving fixed installation

[0046] Combination Figure 3 The first positioning assembly includes a first positioning plate 321, a positioning column 322 and a positioning sleeve 323 which are integrally arranged on the two side walls of the ice guide conveying plate 32. The ice-making body 1 has a positioning plate 11 for the first positioning plate 321 to abut against. The first positioning plate 321 is fixed to the positioning plate 11 by bolts. The positioning column 322 is integrally arranged on the outer wall of the first chamber 311, and is used for positioning and abutting against the connecting plate 241 of the extruder 24. The positioning sleeve 323 passes through the upper and lower end surfaces of the ice guide conveying plate 32, and is used for sleeve positioning with the extrusion body 242 of the extruder 24. Among them, a sealing ring 324 abutting against the extruder 24 is sealed on the inner wall of the positioning sleeve 323 to achieve a sealed installation of the ice guide conveying plate 32 and the extruder 24.

[0047] The second positioning assembly includes a plurality of second positioning plates 331 integrally arranged on the outer wall of the ice guide cover plate 33. In this embodiment, the ice guide cover plate 33 has four second positioning plates 331. One of the second positioning plates 331 is located on the side of the ice guide cover plate 33 away from the extruder 24, and the fixing method of the second positioning plate 331 and the positioning flat plate 11 is consistent with the fixing method of the first positioning plate 321. The other three second positioning plates 331 are circumferentially arranged at one end of the ice guide cover plate 33 close to the extruder 24, and the ice guide conveying plate 32 has a positioning flange 325 for the above three second positioning plates 331 to be positioned and abutted. The positioning column 322 is integrally arranged at the bottom of the positioning flange 325.

[0048] Reference Figure 2 and Figure 5 A sealing assembly 25 is also installed at the bottom of the inner cavity of the ice-making cylinder 21, and the sealing assembly 25 is used to achieve the sealing of the ice-making cylinder 21 and the output motor. The sealing assembly 25 includes a stationary ring 251 fixed to the bottom of the ice-making cylinder 21, a dynamic ring 252 arranged on the top of the static ring 251, and an elastic member 253 connecting the dynamic ring 252 and the static ring 251. The dynamic ring 252 is located at the bottom through hole of the ice-making cylinder 21. The dynamic ring 252 and the static ring 251 are both sealed and sleeved on the output screw 22, and the elastic member 253 is a spring member. When the output screw 22 rotates, the static ring 251 is in a stationary state, the dynamic ring 252 and the output screw 22 rotate synchronously, and the elastic member 253 can buffer the axial movement of the output screw 22 when it rotates.

[0049] The implementation principle of an extruder-type ice maker in the embodiment of the present application is as follows: after the ice cubes are axially output from the output through hole 2421, the ice cubes abut against the abutting conical surface 2422 to bend and break, and the ice cubes in the first chamber 311 that are away from the second chamber 312 are guided by the guide arc surface 3112 to the top surface of the extruder 24, and then, pushed by the subsequently generated ice cubes, the ice cubes on the top of the extruder body 242 are directly pushed into the second chamber 312.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
