Description

Technical Field

[0001] This utility model relates to the field of fluid chiller technology, specifically a temperature control structure for a fluid chiller. Background Technology

[0002] A smoothie machine is a food processing device widely used in the frozen beverage industry. It cools liquids such as fruit juice and dairy products to form ice crystals, creating a smoothie. A traditional smoothie machine includes an ice-making device, which consists of a storage cylinder and an evaporator and scraper installed inside. Liquid is poured into the storage cylinder, cooled by the evaporator to form ice crystals, and then continuously stirred by the scraper to form a smoothie. Finally, the smoothie is discharged through the ice outlet on the storage cylinder.

[0003] Examples include a snow melting machine for making ice cream disclosed in Chinese utility model patent No. CN201220423605.8, a new type of ice cream machine with coupling drive disclosed in Chinese utility model patent No. CN201420201326.6, a home-style ice cream machine disclosed in invention application CN201710076725.2, and a condensation structure and snow melting machine for cold drink equipment disclosed in invention application CN202410556762.3, etc.

[0004] However, the aforementioned smoothie machine cannot determine the ice-making temperature, resulting in an inconsistency in the temperature of the ice crystals produced by the evaporator. If the ice crystal temperature is too high, the outlet will output ice water instead of smoothie; if the ice crystal temperature is too low, the smoothie will turn into large ice blocks or become too hard, clogging the outlet. Therefore, further improvements are necessary. Utility Model Content

[0025] In this embodiment, a temperature detector is mounted on a fixed assembly on the evaporator tank 1. The temperature detector monitors the temperature, ensuring that the temperature of the slush produced by the slush machine is maintained within a certain range. This prevents the slush from melting due to excessive heat, and also prevents it from becoming too hard or forming large ice blocks that clog the outlet, thus ensuring the quality of the slush. Simultaneously, the fixed assembly enhances the stability of the temperature detector, preventing it from detaching from the evaporator tank 1 due to impact from the slush, thus ensuring the stability of the temperature detector in use.

[0026] The fixing assembly includes an end cover plate 5 and a connecting seat 6. The end cover plate 5 and the connecting seat 6 are located on both sides of the barrel opening 2 along the axial direction of the barrel opening 2, respectively. The end cover plate 5 and the connecting seat 6 are fixed to each other. The end cover plate 5 is provided with an end plate opening 7, and the connecting seat 6 is provided with a connecting seat opening 8. The detection head 3 is fixedly mounted on the connecting seat 6, and the detection end of the detection head 3 passes through the connecting seat opening 8 and the end plate opening 7 in sequence. The fixing assembly is a combination structure composed of the end cover plate 5 and the connecting seat 6, used to fix the temperature detector and seal the barrel opening 2.

[0027] In this embodiment, the end cover plate 5 is located in front of the barrel opening 2 and extends towards the barrel opening 2 with a protruding ring. The connecting seat 6 is located behind the barrel opening 2 and extends towards the barrel opening 2 with a covering ring. The covering ring abuts against the rear of the barrel opening 2. The protruding ring passes through the barrel opening 2 and abuts against the inside of the covering ring. In addition, a fixing post hole is provided on the protruding ring, and a fixing mating hole is provided at the corresponding position on the connecting seat 6. The two are then fixed to each other by fasteners, thereby realizing the mutual fixation between the end cover plate 5, the evaporator barrel 1, and the connecting seat 6.

[0028] The detection head 3 is provided with a fixed edge 9, and is fixedly mounted on the connecting seat 6 through the fixed edge 9.

[0029] In this embodiment, the fixed edge 9 extends toward both sides of the detection head 3 and is provided with fixed holes respectively. When the detection head 3 is assembled, its detection end passes through the connecting seat opening 8 and the end plate opening 7 in sequence and then abuts against the connecting seat 6 through the fixed edge 9. The connecting seat 6 is provided with a fixed mating hole corresponding to the fixed hole. The two are then fixed to each other by fasteners, thereby realizing the mutual fixation of the detection head 3 and the connecting seat 6.

[0030] A guide post 10 is provided on the end cover plate 5. The end plate opening 7 is opened on the guide post 10, and a positioning step 11 is provided on it. The detection head 3 is fitted with a detection head seal 12. The detection head 3 passes through the connecting seat opening 8 and is guided and inserted into the end plate opening 7. It is sealed and abutted against the positioning step 11 by the detection head seal 12. This ensures that the detection head 3 is always in a straight line extension and will not bend or deform during operation. After assembly, the detection head 3 is sealed against the positioning step 11 by the detection head seal 12 to prevent ice sand from entering the evaporator tank 1 through the end plate opening 7.

[0031] The barrel opening 2 is opened on the end face of the evaporator barrel 1. The evaporator barrel 1 is provided with a positioning recess 13 corresponding to the barrel opening 2. The end cover plate 5 is provided with an end plate side 14. An end plate seal 15 is provided between the end plate side 14 and the positioning recess 13, and the two are sealed together by the end plate seal 15.

[0032] In this embodiment, the evaporator barrel 1 is open at one end and closed at the other end. A positioning recess 13 is recessed at the center of the closed end of the evaporator barrel 1. A barrel opening 2 is provided on the positioning recess 13. The side edge 14 of the end plate extends outward from the convex ring of the end cover plate 5. When the end cover plate 5 is assembled, it abuts against the front of the positioning recess 13 through the side edge 14 of the end plate. At the same time, the covering ring of the connecting seat 6 abuts against the rear of the positioning recess 13, so that the end cover plate 5 and the connecting seat 6 clamp the positioning recess 13 from front to back. In addition, the end plate seal 15 seals between the side edge 14 of the end plate and the positioning recess 13 to prevent ice sand from entering the evaporator barrel 1 through the position between the side edge 14 of the end plate and the positioning recess 13.

[0033] The end cover plate 5 is provided with an end plate shaft hole 16, and the connecting seat 6 is provided with a connecting seat shaft hole 17. The end plate shaft hole 16 and the connecting seat shaft hole 17 are on the same axis and a drive shaft 18 passes through them.

[0034] In this embodiment, the drive shaft 18 passes through the connecting seat shaft hole 17 and the end plate shaft hole 16 in sequence after passing through the rear end of the evaporator barrel 1, and then extends out of the front end of the evaporator barrel 1, so that the drive shaft 18 can rotate stably on the evaporator barrel 1.

[0035] A sleeve cavity 19 is formed between the end cover plate 5 and the connecting seat 6. An inner bushing 20 is provided in the sleeve cavity 19, and the drive shaft 18 is rotatably engaged with the inner bushing 20.

[0036] In this embodiment, the two end faces of the inner bushing 20 abut against the end cover plate 5 and the connecting seat 6 respectively, so that the inner bushing 20 can be stably assembled on the evaporator barrel 1. In addition, the positioning function of the inner bushing 20 can further stabilize the drive shaft 18 on the evaporator barrel 1.

[0037] The inner wall of the inner bushing 20 is provided with at least one abutting part 21, and the drive shaft 18 abuts against the abutting part 21.

[0038] In this embodiment, the abutting part 21 is provided with two parts, front and back. The two abutting parts 21 abut against different positions at the front and back of the drive shaft 18 respectively, so as to ensure that the drive shaft 18 and the inner bushing 20 are always on the same axis, so as to avoid the problem of eccentricity of the drive shaft 18 when rotating.

[0039] A sleeve 22 is also provided on the shaft hole 17 of the connecting seat. One end of the sleeve 22 is provided with a positioning edge 23, and it is positioned between the inner bushing 20 and the connecting seat 6 through the positioning edge 23. The drive shaft 18 is rotatably engaged with the sleeve 22.

[0040] In this embodiment, the sleeve 22 is fitted onto the shaft hole 17 of the connecting seat and positioned between the inner bushing 20 and the connecting seat 6 by the positioning edge 23, so as to prevent the sleeve 22 from falling off the evaporator barrel 1. In addition, the drive shaft 18 also rotates on the sleeve 22, thereby further improving the rotational stability of the drive shaft 18.

[0041] At least one anti-rotation positioning part 24 is provided around the axis on the annular end face of the barrel opening 2.
