Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to a temperature detection structure for frozen food manufacturing equipment. Background Technology
[0002] In existing vertical snow melting machine structures, the machine body typically adopts a vertical columnar layout. The material tank, refrigeration evaporator, and stirring mechanism extend from the top of the machine body to the sides in a cantilevered manner, while the compressor, condenser, and throttling element are housed within the machine body. The refrigeration evaporator generally includes a cylindrical component and refrigeration pipes coiled along its inner circumference along its height. The stirring mechanism includes a drive shaft extending downwards along the axial direction of the cylindrical component and an impeller connected to the lower end of the drive shaft. The material tank is fitted around the refrigeration evaporator and the impeller, and the impeller can contact the outer circumference of the cylindrical component and the inner circumference of the material tank.
[0003] The container holds raw materials for processing into frozen foods. The raw materials adhering to the outer wall of the cylindrical component cool into ice flakes or an ice-water mixture. The agitator scrapes off the ice flakes or ice-water mixture and stirs it at low temperatures to form frozen foods such as ice cream, sorbet, and sorbet. Excessively high or low temperatures within the container will affect the quality of the finished product. Therefore, a temperature sensing element is usually required to control the start and stop of the evaporator. To avoid affecting the normal rotation of the agitator, the temperature sensing element is located at the bottom of the cylindrical component. The conductive wire of the temperature sensing element needs to be positioned in a pre-designed channel inside the cylindrical component, which is disadvantageous for manufacturing and assembly, especially for evaporators with smaller diameters.

[0024] See Figures 1 to 3 The present invention discloses a temperature sensing structure for a frozen food manufacturing equipment, comprising: a body 100 extending vertically; a cantilever portion 200 extending from the side at the top of the body 100; a downwardly extending refrigeration evaporator 300 provided in the cantilever portion 200; the refrigeration evaporator 300 including an inner cylinder 310 and an outer cylinder 320 concentrically fitted outside the inner cylinder 310; and a refrigeration pipe 3 coiled along the height direction between the inner cylinder 310 and the outer cylinder 320. 30. The bottom of the outer cylinder 320 is provided with a lower end plate 321. The lower end plate 321 is equipped with a bushing assembly 400 coaxial with the axis of the outer cylinder 320. A drive shaft 500 is rotatably mounted on the bushing assembly 400. A temperature sensing element 600 located on one side of the drive shaft 500 is mounted on the bushing assembly 400. The lower end of the temperature sensing element 600 passes through the lower end plate 321, and the upper end of the temperature sensing element 600 extends upward and is located inside the inner cylinder 310.
[0025] The temperature sensing structure of the above-mentioned frozen food manufacturing equipment has a refrigeration pipe 330 coiled between the inner cylinder 310 and the outer cylinder 320. The drive shaft 500, which is connected to the stirring impeller, is inserted through the lower end plate 321 of the outer cylinder 320. A bushing assembly 400, which is rotatably connected to the drive shaft 500, is set on the lower end plate 321 of the outer cylinder 320. A temperature sensing element 600 protruding downward from the outer cylinder 320 is set on the bushing assembly 400. The upper end of the temperature sensing element 600 extends into the inner cylinder 310. The upper end of the temperature sensing element 600 can be connected to an electric wire. The electric wire is threaded from the inside of the inner cylinder 310 to the machine body 100. Thus, without affecting the normal operation of the stirring impeller, it is suitable for refrigeration evaporators with smaller diameters, and it is also beneficial to the manufacturing and assembly of the refrigeration evaporator 300 and the temperature sensing element 600.
[0026] See Figure 3 and Figure 4In some embodiments of this utility model, the lower end plate 321 is provided with a through mounting port 322 in the middle. The bushing assembly 400 includes a mounting base 410, a cover 420, and a shaft seal 430. The mounting base 410 is provided with a first sleeve 411 that passes through the mounting port 322. The shaft seal 430 is located inside the first sleeve 411 and allows the drive shaft 500 to pass through. The cover 420 has a second sleeve 421 that is coaxially nested with the first sleeve 411. The mounting base 410 and the cover 420 have a connection structure that passes through the mounting port 322 and is located outside the first sleeve 411, so that the lower end plate 321 is clamped between the mounting base 410 and the cover 420, and the shaft seal 430 is clamped between the second sleeve 421 and the mounting base 410. Understandably, when the drive shaft 500 is rotatably mounted on the lower end plate 321 of the outer cylinder 320, the shaft seal 430 can be placed in the first sleeve 411, the mounting base 410 can be placed against the lower surface of the lower end plate 321, and the first sleeve 411 can be passed through the mounting port 322. Then, the cover 420 can be placed against the upper surface of the lower end face, and the second sleeve 421 can be inserted into the first sleeve 411. At this time, the lower end of the second sleeve 421 will press the shaft seal 430 tightly into the first sleeve 411 and fix it. Then, the drive shaft 500 passes through the second sleeve 421, the shaft seal 430 and the first sleeve 411 in sequence to prevent the shaft seal 430 from loosening. The shaft sleeve assembly 400 with the above structure is very convenient for production and assembly, has a simple structure and low manufacturing difficulty.
[0027] See Figure 3 and Figure 4 In some embodiments of this utility model, the mounting port 322 includes a circular hole 323 and at least two first through holes 324 formed on the outer periphery of the circular hole 323. The mounting base 410 has a first threaded post 412 passing through the first through hole 324 on the outer periphery of the first sleeve 411. The cover 420 has a sleeve portion 422 sleeved on the outer periphery of the second sleeve 421 and fitted onto the first threaded post 412. Threaded fasteners pass through the sleeve portion 422 and are tightened onto the first threaded post 412. It is understood that using threaded fasteners to pass through the sleeve portion 422 and tighten onto the first threaded post 412 makes the installation and disassembly between the mounting base 410 and the cover 420 very convenient and easy to operate. Moreover, the cooperation of at least two through holes and at least two first threaded posts 412 helps to position the angular position of the mounting base 410 and the cover 420, preventing relative deflection that could affect the rotational stability of the drive shaft 500.
[0028] See Figure 3 and Figure 4In some embodiments of this utility model, in order to enable the temperature sensing element 600 to be installed on the mounting base 410 and the cover 420, the mounting opening 322 further includes a second through hole 325 formed on the outer periphery of the circular hole portion 323, and the temperature sensing element 600 is inserted through the second through hole 325 so that the lower end of the temperature sensing element 600 extends to the bottom of the mounting base 410.
[0029] See Figure 3 and Figure 4 In some embodiments of this utility model, a first sealing ring 700 is sandwiched between the mounting base 410 and the lower surface of the lower end plate 321. The first sealing ring 700 has a through hole for avoiding the first sleeve 411 and the first threaded post 412. The first sealing ring 700 has a rubber sleeve 710 for the temperature sensing element 600 to pass through and to be tightly fitted with the temperature sensing element 600. It should be noted that a material tank is fitted outside the refrigeration evaporator 300 and the stirring impeller. The material tank contains raw materials of liquid to be processed. During the stirring process, the raw materials can easily enter the interior of the outer cylinder 320 through the gap between the mounting base 410 and the lower end plate 321, and can also easily enter the interior of the outer cylinder 320 through the gap between the temperature sensing element 600 and the mounting base 410, thus causing hygiene and safety problems. The first sealing ring 700 in the above structure can solve the above problems.
[0030] See Figure 2 and Figure 4 In some embodiments of this utility model, the cantilever portion 200 includes a side extension plate 210 extending horizontally along one side of the body 100 and a side extension shell 220 covering the side extension plate 210. The side extension plate 210 is provided with an installation channel 211 for the outer cylinder 320 to pass through. The upper end of the inner cylinder 310 is welded and fixed to the inner circumferential wall of the outer cylinder 320. In order to facilitate the installation and fixing of the refrigeration evaporator 300 on the cantilever portion 200, The upper end of the outer cylindrical barrel 320 has an outwardly folded annular flange 326. The annular flange 326 is provided with a plurality of mounting holes 327 spaced around its circumference. The side extension plate 210 is provided with second threaded posts 212 corresponding to the mounting holes 327 one by one. The annular flange 326 abuts against the upper end face of all the second threaded posts 212. The entire refrigeration evaporator 300 can be installed and fixed by passing fastening screws through the mounting holes 327 and tightening them onto the second threaded posts 212.
[0031] See Figure 4In some embodiments of this utility model, a second sealing ring 800 is provided between the inner periphery of the mounting channel 211 and the upper outer peripheral wall of the outer cylinder 320. The outer peripheral wall of the second sealing ring 800 abuts against the inner periphery of the mounting channel 211, and the inner peripheral wall of the second sealing ring 800 is provided with two elastic deformation rings spaced apart along the height direction, which are tightly fitted to the outer peripheral wall of the outer cylinder 320. It is understood that during the mixing process, the raw material can easily seep into the interior of the cantilever 200 from the joint between the outer cylinder and the mounting channel 211, thereby causing hygiene and safety problems. The second sealing ring 800 can solve this problem.
[0032] See Figure 4 In some embodiments of this utility model, in order to prevent the second sealing ring 800 from dislodging from the set position, the upper end of the second sealing ring 800 is formed with a mounting ring 810 sandwiched between the lower end face of the annular flange 326 and the upper port of the mounting channel 211. The mounting ring 810 is provided with a clearance hole for avoiding the second threaded post 212. That is, after the fastening screw passes through the mounting hole 327 and the clearance hole, it is tightened to the second threaded post 212, thus fixing the outer cylinder 320 and fixing the second sealing ring 800 at the same time.
[0033] See Figure 2 In some embodiments of this utility model, the interior of the inner cylinder 310 is filled with foam 900 arranged along the height direction of the inner cylinder 310. The foam 900 has a first elongated hole 901 and a second elongated hole extending along its length. The first elongated hole 901 is used to pass through the temperature sensing element 600, and the second elongated hole is used to pass through the refrigerant pipe adjacent to the refrigeration pipe 330. The foam 900 filling the interior of the inner cylinder 310 prevents some of the cold energy generated by the refrigeration pipe 330 from escaping outwards through the inner circumferential wall of the inner cylinder 310. The foam 900 also wraps around the portion of the refrigerant pipe extending into the inner cylinder 310, thereby effectively preventing cold energy loss and improving refrigeration efficiency.
[0034] See Figure 2 In some embodiments of this utility model, the foam body 900 is composed of two foam columns with a fan-shaped cross-section. The outer peripheral wall of the foam column is tightly fitted with the inner peripheral wall of the inner cylinder 310, and the drive shaft 500 passes through the central channel 920 of the two foam columns. The fact that the foam body 900 is composed of two foam columns facilitates its installation inside the inner cylinder 310, resulting in better filling of the inner cylinder 310 and thus better insulation. It also facilitates the installation of refrigerant pipes and reduces production difficulty.
[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
