Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration, and particularly relates to an inverted suspension type ice making evaporator. Background Art
[0002] An ice maker is a refrigeration device that conducts heat exchange between water and a refrigerant. The ice maker mainly includes an ice making evaporator and a refrigeration system. The refrigeration system is used to provide the cold source required for ice making to the ice making evaporator. According to different ice making principles, the ice making evaporator is generally divided into a spray type, an immersion type, and an extrusion type. Among them, the structure of the extrusion type ice maker generally includes an evaporator and a spiral ice scraping mechanism. The spiral ice scraping mechanism spirally pushes the ice formed in the evaporator upward through a screw rod and extrudes it from the ice extrusion port to form an ice strip. Under the action of a ice breaking assembly, the ice strip is broken into granular form.
[0003] The existing ice making evaporator includes a lower support, a cylinder body, a spiral ice scraping mechanism, an upper support, an input pipe, and a refrigeration unit. One end of the cylinder body is fixed to the lower support, and the other end of the cylinder body is fixed to the upper support. A part of the spiral ice scraping mechanism is located inside the cylinder body. One end of the spiral ice scraping mechanism is rotatably matched with the lower support, and the other end of the spiral ice scraping mechanism is rotatably matched with the upper support. An ice outlet is provided on the upper support. The input pipe is connected to the cylinder body. The scraper is spirally wound around the cutter shaft. The refrigeration unit is arranged on the outer peripheral surface of the cylinder body.
[0004] For the ice making evaporator with the above structure, the lower end of the spiral ice scraping mechanism is connected to a driving mechanism that drives the spiral ice scraping mechanism. For example, a reduction motor is connected to the lower end of the spiral ice scraping mechanism. When the reduction motor works, it drives the spiral ice scraping mechanism to rotate. However, since a through hole is provided on the lower support, therefore, a sealing assembly needs to be arranged between the spiral ice scraping mechanism and the through hole. After adopting the sealing assembly, not only the assembly is more troublesome, the cost of the product will also increase, but also there will be a phenomenon of water leakage after long-term use. Summary of the Utility Model
[0005] The utility model provides an inverted suspension type ice making evaporator, which can avoid water leakage.
[0006] The technical solution for solving the above technical problem is as follows:
[0007] The inverted suspension type ice making evaporator includes a cylinder body, an upper support, a spiral ice scraping mechanism, and a refrigeration unit. One end of the cylinder body is fixed to the upper support. An input component is provided on the cylinder body. A part of the spiral ice scraping mechanism is located inside the cylinder body. One end of the spiral ice scraping mechanism is rotatably matched with the upper support. An ice outlet is provided on the upper support. The refrigeration unit is arranged on the outer peripheral surface of the cylinder body. It further includes a bottom cover and a lower support. The bottom cover closes the other end of the cylinder body and is fixed to the cylinder body. The lower support is located inside the cylinder body and is matched with the cylinder body. After that, the bottom cover forms a support for the lower support. The other end of the spiral ice scraping mechanism is rotatably matched with the lower support.
[0008] In the present utility model, after the bottom cover closes the other end of the cylinder body and is fixed to the cylinder body, the problem of water leakage is completely avoided. In addition, the internal structure does not need to consider the sealing problem, the structure is simplified compared with the structure in the background technology, and the cost is also reduced. The evaporation box formed by the cooperation of the corrugated pipe and the cylinder body has a good ice-making effect. Description of the Drawings

[0024] As Figures 1 to 8 shown, the inverted hanging type ice making evaporator of the present utility model includes a cylinder body 1, an upper support 2, a spiral ice scraping mechanism 3, and a refrigeration unit. The following will detail each part and the relationships therebetween.
[0025] In this embodiment, an input component 1a is provided on the cylinder body 1, and water enters the interior of the cylinder body 1 through the input component 1a. A damping groove 1b for reducing the ice output speed is provided on the inner wall surface of the cylinder body 1. The damping groove 1b preferably adopts a spiral groove. After the spiral ice scraping mechanism scrapes the ice condensed on the inner wall surface of the cylinder body 1, the state of this ice is broken ice. Since the spiral ice scraping mechanism lifts these broken ice, when the broken ice encounters the damping groove during the lifting process, the damping has a damping effect on the broken ice, slowing down the speed at which the broken ice is lifted, thereby increasing the condensation time of these broken ice in the cylinder body 1 and making the ice bar extruded from the ice outlet 2a in a hard state.
[0026] The structure of the cylinder body 1 is hollow and has openings at both ends. One end of the cylinder body 1 is fixed to the upper support 2. In this embodiment, an ice outlet 2a is provided on the upper support 2. The upper support 2 is composed of a sleeve 2b and a seat body 2c fixed to the sleeve 2b. The sleeve 2b is sleeved on the cylinder body 1 and connected to the cylinder body 1. The sleeve 2b and the cylinder body 1 preferably adopt a threaded connection. The ice outlet 2a is provided on the seat body 2c. A stepped hole 2d is also provided on the seat body 2c, and this assembly hole is used for rotational cooperation with the spiral ice scraping mechanism 3. A convex block 2e for facilitating the application of torque when the upper support 2 and the cylinder body 1 are threadedly connected is further provided on the circumferential surface of the upper support 2. There are multiple convex blocks 2e and they are evenly arranged along the circumferential surface of the upper support 2.
[0027] A part of the spiral ice scraping mechanism is located inside the cylinder body 1, and one end of the spiral ice scraping mechanism 3 is rotationally matched with the upper support 2. The spiral ice scraping mechanism 3 includes a cutter shaft 3a, a spiral cutter 3b, and an upper shaft sleeve 3c. The spiral cutter 3b is spirally wound around the cutter shaft 3a and fixed to the cutter shaft 3a. A step 3d is provided on the cutter shaft 3a. After the upper shaft sleeve 3c is sleeved on the cutter shaft 3a, one end of the upper shaft sleeve 3c is axially limited by the step 3d. After one end of the cutter shaft 3a passes through the stepped hole 2d and is exposed outside the cylinder body 1 and the upper support 2, the other end of the upper shaft sleeve 3c is axially limited by the step in the stepped hole 2d.
[0028] A pressure relief hole 3e is provided on the circumferential surface of the cutter shaft 3a. The pressure relief hole 3e is composed of a radial hole opened along the radial direction of the cutter shaft 3a and an axial hole opened along the axial direction of the cutter shaft 3a. An installation hole 3f is provided at the upper end of the cutter shaft 3a. The installation hole 3f communicates with the axial hole in the pressure relief hole 3e. The installation hole 3f is polygonal, and the output end of the motor is matched with the installation hole 3f.
[0029] The present utility model further includes a bottom cover 4 and a lower support 5. The bottom cover 4 closes the other end of the cylinder body 1 and is fixed to the cylinder body 1. The lower support 5 is located inside the cylinder body 1 and cooperates with the cylinder body 1. The bottom cover 4 forms a support for the lower support 5. The other end of the spiral ice scraping mechanism 3 is rotationally matched with the lower support 5.
[0030] The bottom cover 4 and the cylinder body 1 are preferably fixed by welding, which completely avoids water leakage from the bottom of the ice maker. The bottom cover 4 includes a chassis 4a and a positioning projection 4b. The diameter of the chassis 4a is larger than that of the positioning projection 4b. The positioning projection 4b is inserted into the cylinder body 1, and the chassis 4a is welded to the cylinder body 1.
[0031] The material of the lower support 5 is preferably UPE (i.e., ultra-high molecular weight polyethylene, English name Ultra-high molecular weight polyethylene). UPE is similar to polyamide and polytetrafluoroethylene. UPE has wear resistance, impact resistance, corrosion resistance, self-lubrication, and shock absorption. Its wear resistance exceeds that of carbon steel. UPE has the best wear resistance among plastics and is 8 times that of ordinary carbon steel. UPE has the highest impact strength among plastics and is 6 times that of ABS. UPE's self-lubrication performance is equivalent to that of polytetrafluoroethylene, and its price is only 1 / 8 of it. UPE has strong corrosion resistance, high chemical technical performance, is hygienic and healthy, is resistant to low temperature, and has ductility under liquid nitrogen. The UPE in this embodiment is food-grade UPE.
[0032] The lower support 5 includes a bushing 5a and a support seat 5b. The other end of the spiral ice scraping mechanism 3 is inserted into the bushing 5a and is rotationally matched with the bushing 5a. In this embodiment, the cutter shaft 3a and the bushing 5a are in clearance fit, so that the cutter shaft 3a can rotate relative to the bushing 5a. In this embodiment, the support seat 5b is fixed to the bushing 5a, and the support seat 5b is fixed to the cylinder body 1. The support seat 5b and the cylinder body 1 are in interference fit to fix the support seat 5b and the cylinder body 1.
[0033] A disc-shaped component 6 for protecting the lower support 5 is provided on the spiral ice scraping mechanism 3. The axial end face of the disc-shaped component 6 is matched with the axial end face of the lower support 5. The disc-shaped component 6 is integrally formed with the cutter shaft 3a. The lower end of the spiral ice scraper 3b is fixed to the disc-shaped component 6 integrally, so as to improve the elasticity of the spiral ice scraping mechanism 3. Since the cutter shaft 3a and the bushing 5a are in clearance fit, in this embodiment, the axial end face of the disc-shaped component 6 is attached to the axial end face of the bushing 5a, which can prevent the broken ice scraped by the spiral ice scraper 3b from falling into the bushing 5a, and further prevent the bushing 5a from being damaged.
[0034] The refrigeration unit is arranged on the outer peripheral surface of the cylinder body 2. The refrigeration unit includes a corrugated pipe 7. An input port 8 for refrigerant input and an output port 9 for refrigerant output are provided on the corrugated pipe 7. The corrugated pipe 7 is sleeved on the cylinder body 2, and both ends of the corrugated pipe 7 are fixed to the cylinder body 2 respectively. A flow channel 10 for refrigerant flow is formed between the corrugated pipe 7 and the cylinder body 2. The length of the corrugated pipe 7 can be increased or reduced according to the overall length of the product.
[0035] The corrugated pipe 7 includes a trough section 7a and a crest section 7b. The trough section 7a is in contact with the outer wall surface of the cylinder 2, and this contact relationship forms a seal between the trough section 7a and the cylinder 2. The flow channels 10 are surrounded by the trough section 7a, the crest section, and the cylinder 2. There are multiple flow channels 10, and a drainage groove 7c for the refrigerant to flow between adjacent two flow channels 10 is provided on the trough section 7a.
[0036] There is one input port 8, which is located on the crest section 7b at the lower part of the corrugated pipe 7, and there is one output port 9, which is located on the crest section 7b at the upper part of the corrugated pipe 7. The angular difference in the circumferential direction between the drainage grooves 7c on adjacent two trough sections 7a is 180°. The angular difference in the circumferential direction between the input port 8 and the drainage groove 7c on the trough section 7a adjacent to the input port 8 is 180°, and the angular difference in the circumferential direction between the output port 9 and the drainage groove 7c on the trough section 7a adjacent to the output port 9 is 180°.
[0037] The number of crest sections 7b is an even number, which facilitates the input port 8 and the output port 9 to be located on the crest sections 7b at both ends of the corrugated pipe 7, and ensures that the angular difference in the circumferential direction between the above-mentioned input port 8 and the drainage groove 7c on the adjacent trough section 7a is 180°, and ensures that the angular difference in the circumferential direction between the output port 9 and the drainage groove 7c on the trough section 7a adjacent to the output port 9 is 180°.
[0038] Based on the above structure, when the refrigerant is input from the input port 8, the refrigerant flows along the flow channels 10 on the left and right sides of the input port 8. When the refrigerant in the flow channel 10 reaches the drainage groove 7c, the refrigerant is drained to the next layer of flow channel 10 through the drainage groove 7c, and the refrigerant flows along this flow channel 10 and finally is output from the output port 9. During this process, since each flow channel 10 is filled with refrigerant, therefore, these refrigerants directly exchange heat with the circumferential surface of the cylinder 2 to cool the water flowing into the cylinder 2, improving the uniformity of refrigeration. In addition, since the refrigerant directly cools the cylinder 2, it avoids the barrier of the spiral coil pipe wall in the middle like a spiral coil pipe, so the refrigeration efficiency is significantly improved.
[0039] The corrugated pipe 7 further includes a connection section 7d. The connection section 7d is connected to the crest sections 7b at both ends of the corrugated pipe 7. The connection section 7d is used to fix to the cylinder 2. In this embodiment, the connection section 7d and the crest section 7b are integrally formed, and the connection section 7d is preferably fixed to the cylinder 2 by welding.
