Description

Technical Field

[0001] This utility model relates to the field of ice maker technology, and in particular to an extrusion ice maker. Background Technology

[0002] Currently, the core component of granular ice makers on the market is a sealed chamber with an ice-making tubular structure. Water in the sealed chamber is turned into ice by a refrigerant, and then the ice is scraped by a spiral structure on an ice scraper on the inner wall of the ice-making tube, and then pushed out of the shaper to complete the ice-making process.

[0003] For example, Chinese patent CN112484345A discloses an evaporator for an ice maker, which includes a cylinder and a spiral push rod disposed in the cylinder. The cylinder includes an inner tube and an outer tube sleeved outside the inner tube and closed at both ends with the inner tube. The bottom end of the inner tube is connected to a water inlet pipe and a water outlet pipe, and the top end of the inner tube forms an ice outlet hole. A cavity for containing refrigerant is formed between the outer tube and the inner tube. The upper and lower ends of the outer tube are respectively connected to a refrigerant outlet pipe and a refrigerant inlet pipe.

[0004] In the aforementioned prior art, the cylinder is fixedly mounted on the motor housing, and the spiral push rod that scrapes ice is connected to the output shaft of the motor through a reduction mechanism. The spiral push rod generates a downward axial force during the process of squeezing the ice. This load is applied to the connection between the bottom of the cylinder and the motor, as well as to the motor. The connection needs to be reinforced to ensure structural and connection strength, resulting in relatively high structural costs.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an extrusion-type ice-making device with a reasonable structure, the ability to transfer screw extrusion stress, a simplified overall structure, and reduced production costs.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The present invention discloses an extrusion-type ice-making device, comprising a motor and an evaporation assembly. The upper end of the evaporation assembly is provided with an ice extruder, and an ice scraper screw is provided inside the evaporation assembly. The upper end of the ice scraper screw is rotatably connected to the ice extruder, and the lower end of the ice scraper screw is drively connected to the motor. A support frame is provided between the evaporation assembly and the motor, and the lower end of the ice scraper screw is rotatably connected to the support frame. A connecting piece is provided between the support frame and the ice extruder.

[0009] During ice making, the evaporation assembly uses an ice-scraping screw to push internal ice shavings towards an ice extruder. The ice shavings are continuously squeezed into the ice outlet of the extruder, forming granular ice blocks. The operation of the ice-scraping screw generates a significant downward force, which is applied to the support frame rotatably connected to the screw and transmitted to the ice extruder through connectors. Furthermore, this downward force ensures a tighter fit between the ice extruder and the evaporation assembly, and counteracts the upward thrust of the ice shavings during extrusion. The ice-scraping screw and evaporation assembly can self-relax during operation, avoiding stress on the motor, reducing the strength requirements of the motor structure, and thus lowering overall production costs.

[0010] According to the above scheme, the support frame is equipped with a bearing, the outer ring of which is fixedly connected to the support frame, and the lower end of the ice-scraping screw is connected to the inner ring of the bearing. The ice-scraping screw is rotatably connected to the support frame through the bearing. As a rigid structure, the bearing can apply the force generated by the ice-scraping screw to the support frame, and then transmit it to the ice extruder through the connecting parts.

[0011] According to the above scheme, the support frame is provided with a stepped hole, and the bearing is installed in the stepped hole, with the outer ring of the bearing fixedly connected to the stepped hole. The lower end of the ice scraper screw is provided with an input terminal, which abuts against the inner ring of the bearing. The input terminal passes through the inner ring of the bearing and is thus connected to the motor drive. The bearing is embedded in the stepped hole and thus installed on the support frame, with the ice scraper screw abutting against the inner ring of the bearing to make it rotatably connected to the support frame. Further, the input terminal at the lower end of the ice scraper screw passes through the inner ring of the bearing, and the output shaft of the motor is connected to the input terminal. It can be understood that the input terminal and the output shaft of the motor are provided with a spline structure to form a transmission connection. The spline transmission does not transmit axial stress, thereby avoiding the force on the ice scraper screw being applied to the motor and causing power loss.

[0012] According to the above scheme, the connector includes several connecting rods, the ice extruder has several lugs, and the support frame has several threaded holes. The lugs and threaded holes are arranged in a one-to-one correspondence. The two ends of the connecting rods are connected to the lugs and threaded holes respectively, thereby fixing the ice extruder to the support frame. The connecting rods can use conventional bolts. The lugs are integrally formed on the ice extruder, and the threaded holes are easily machined. The connecting rods pass through the lugs and connect to the threaded holes, thus fixing the ice extruder to the support frame. The overall structure is simple and can effectively reduce production costs.

[0013] According to the above scheme, the support frame is fixedly connected to the motor housing. As mentioned above, the support frame is an independent accessory, and an ear / hole structure can be provided on the support frame. The support frame is fixedly connected to the motor housing by bolts.

[0014] According to the above scheme, the support frame is integrally set on the motor housing. As an integrally formed structure of the motor housing, the support frame can reduce the number of parts, and the integral forming process can further reduce the production cost.

[0015] According to the above scheme, the evaporation assembly includes an ice-making bucket and a bucket base. An evaporator is provided on the outer wall of the ice-making bucket. The ice squeezer cover is installed on the upper port of the ice-making bucket, and the bucket base seals the lower port of the ice-making bucket. A first sealing ring is provided between the bucket base and the ice-making bucket. A water inlet pipe communicating with the inner cavity of the ice-making bucket is provided on the bucket base. The bucket base seals the lower port of the ice-making bucket, and the water inlet pipe can continuously supply water to the inner cavity of the ice-making bucket through the bucket base. When the evaporator is working, ice slush is formed inside the ice-making bucket, and under the pushing action of the ice scraper screw, it is formed into granular ice blocks through the ice squeezer.

[0016] According to the above scheme, the bucket base is provided with a central through hole, which is concentric with the stepped hole. A second sealing ring is provided between the ice scraper screw and the central through hole. The central through hole can be through which the input terminal at the lower end of the ice scraper screw passes, and the input terminal is connected to the output shaft of the motor. The second sealing ring is used to prevent water leakage at the central through hole.

[0017] This invention relates to an extrusion-type ice-making device. During ice making, the ice-scraping screw generates a significant downward force, which is transmitted to the ice extruder through a connector and counteracts the upward thrust of the ice during extrusion molding. The ice-scraping screw and evaporation assembly can self-eliminate working stress during operation, avoiding pressure on the motor, reducing the strength requirements of the motor structure, and thus lowering overall production costs.

[0024] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1-3 As shown, the extrusion-type ice-making device of this utility model includes a motor 1 and an evaporation assembly. The upper end of the evaporation assembly is provided with an ice extruder 2, and the evaporation assembly is provided with an ice scraper screw 3. The upper end of the ice scraper screw 3 is rotatably connected to the ice extruder 2, and the lower end of the ice scraper screw 3 is drivenly connected to the motor 1. A support frame 4 is provided between the evaporation assembly and the motor 1, and the lower end of the ice scraper screw 3 is rotatably connected to the support frame 4. A connecting piece is provided between the support frame 4 and the ice extruder 2.

[0027] During ice making, the ice-scraping screw 3 pushes the internal ice shavings towards the ice extruder 2. The ice shavings are continuously squeezed into the ice outlet of the ice extruder 2, forming granular ice blocks. The operation of the ice-scraping screw 3 generates a significant downward force, which is applied to the support frame 4, rotatably connected to the ice-scraping screw 3, and transmitted to the ice extruder 2 through the connector. Furthermore, this downward force ensures a tighter fit between the ice extruder 2 and the evaporation assembly, and counteracts the upward thrust of the ice shavings during extrusion. The ice-scraping screw 3 and the evaporation assembly can self-relax during operation, avoiding pressure on the motor 1, reducing the strength requirements of the motor 1 structure, and thus lowering overall production costs.

[0028] The support frame 4 is equipped with a bearing 41. The outer ring of the bearing 41 is fixedly connected to the support frame 4, and the lower end of the ice scraper screw 3 is connected to the inner ring of the bearing 41. The ice scraper screw 3 is rotatably connected to the support frame 4 through the bearing 41. As a rigid structure, the bearing 41 can apply the force generated by the ice scraper screw 3 to the support frame 4, and then transmit it to the ice extruder 2 through the connecting parts.

[0029] The support frame 4 has a stepped hole 42, and a bearing 41 is disposed within the stepped hole 42. The outer ring of the bearing 41 is fixedly connected to the stepped hole 42. The lower end of the ice scraper screw 3 has an input terminal 31, which abuts against the inner ring of the bearing 41. The input terminal 31 passes through the inner ring of the bearing 41 and is thus connected to the motor 1 for transmission. The bearing 41 is embedded in the stepped hole 42 and thus mounted on the support frame 4. The ice scraper screw 3 abuts against the inner ring of the bearing 41, making it rotatably connected to the support frame 4. Furthermore, the input terminal 31 at the lower end of the ice scraper screw 3 passes through the inner ring of the bearing 41, and the output shaft of the motor 1 is connected to the input terminal 31 for transmission. It can be understood that the input terminal 31 and the output shaft of the motor 1 are provided with a spline structure to form a transmission connection. The spline transmission does not transmit axial stress, thereby avoiding the force on the ice scraper screw 3 being applied to the motor 1 and causing power loss.

[0030] The connector includes several connecting rods 5, several lugs 21 on the ice extruder 2, and several threaded holes 43 on the support frame 4. Each lug 21 corresponds to one of the threaded holes 43. The two ends of the connecting rods 5 are connected to the lugs 21 and the threaded holes 43 respectively, thus fixing the ice extruder 2 to the support frame 4. The connecting rods 5 can use conventional bolts. The lugs 21 are integrally formed on the ice extruder 2, and the threaded holes 43 are easily machined. The connecting rods 5 pass through the lugs 21 and connect to the threaded holes 43, thereby fixing the ice extruder 2 to the support frame 4. The overall structure is simple and can effectively reduce production costs.

[0031] The support frame 4 is fixedly connected to the housing of the motor 1. As mentioned above, the support frame 4 is an independent accessory. The support frame 4 can be provided with an ear / hole structure and is fixedly connected to the housing of the motor 1 by bolts.

[0032] The evaporation assembly includes an ice-making bucket 22 and a bucket base 23. An evaporator 24 is provided on the outer wall of the ice-making bucket 22. The ice squeezer 2 is fitted onto the upper port of the ice-making bucket 22, and the bucket base 23 is sealed onto the lower port of the ice-making bucket 22. A first sealing ring 25 is provided between the bucket base 23 and the ice-making bucket 22. A water inlet pipe 26 communicating with the inner cavity of the ice-making bucket 22 is provided on the bucket base 23. The bucket base 23 seals the lower port of the ice-making bucket 22, and the water inlet pipe 26 can continuously supply water to the inner cavity of the ice-making bucket 22 through the bucket base 23. When the evaporator 24 is working, ice slush is formed inside the ice-making bucket 22, and under the pushing action of the ice scraper screw 3, it is formed into granular ice blocks by the ice squeezer 2.

[0033] The bucket base 23 is provided with a central through hole 27, which is concentrically arranged with the stepped hole 42. A second sealing ring 28 is provided between the ice scraper screw 3 and the central through hole 27. The central through hole 27 can be through which the input terminal 31 at the lower end of the ice scraper screw 3 passes. The input terminal 31 is connected to the output shaft of the motor 1 for transmission. The second sealing ring 28 is used to prevent water leakage at the central through hole 27.

[0034] Example 2

[0035] like Figure 4 As shown, the only difference between this embodiment and Embodiment 1 is that the support frame 4 is integrally set on the housing of the motor 1. The support frame 4 is an integrally formed structure of the housing of the motor 1, which can reduce the number of parts, and the integral forming process can further reduce the production cost.
