Description

Technical Field

[0001] This utility model relates to the field of smoothie machine technology, and specifically to a smoothie machine with temperature detection function. Background Technology

[0002] Currently, most smoothie makers on the market use a wound-tube evaporator, where metal tubes are wrapped around the outer wall of the ice-making bucket. When the compressor is working, the liquid refrigerant in the evaporator evaporates and absorbs heat from the ice-making bucket, causing the water inside to freeze. However, the gap between the metal tubes and the outer wall of the ice-making bucket is difficult to maintain, affecting cooling efficiency. Furthermore, the heat in the water must pass through the ice-making bucket and the evaporator before being absorbed by the refrigerant, resulting in a long heat conduction path and low heat transfer efficiency, thus reducing ice-making efficiency. In addition, the wound-tube evaporator requires a significant amount of time to wind the metal tubes onto the outer wall of the ice-making bucket during production, leading to low production efficiency, and the quality of the winding also significantly impacts cooling efficiency.

[0003] Utility model patent CN119879456A discloses a direct-injection refrigeration slush machine. This prior art uses a flooded evaporator instead of a coiled evaporator. By connecting the evaporation chamber inside the ice-making bucket in series with the compression refrigeration assembly, the refrigerant can directly evaporate and absorb heat inside the ice-making bucket, eliminating the need for multiple layers of heat conduction. This simplified heat conduction path significantly improves heat exchange efficiency, thus greatly increasing ice-making efficiency. Furthermore, using a flooded evaporator instead of a coiled evaporator eliminates the complex process of winding metal tubes around the outer wall of the ice-making chamber, greatly simplifying the production process, improving efficiency, and avoiding the problem of improper winding affecting refrigeration efficiency. However, this prior art still has structural shortcomings. It cannot obtain the ice-making temperature, especially the temperature at the ice outlet. If the temperature at this location is too high, the output may be ice water instead of slush; if the temperature is too low, the slush will become large ice blocks or be too hard, clogging the outlet and preventing the desired slush shape. Therefore, obtaining the temperature at the ice outlet is crucial.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model provides a smoothie machine with a temperature detection function. The temperature sensor is fixed on the evaporator and correspondingly set to the ice outlet. This allows for more accurate detection of the temperature at the ice outlet, ensuring that the temperature of the smoothie at the outlet is maintained within a certain range. This guarantees normal ice dispensing, preventing the smoothie from melting due to excessively high temperatures at the outlet, and also preventing the smoothie from becoming too large or too hard due to excessively low temperatures, which could clog the outlet, hinder ice dispensing, and ultimately prevent the desired smoothie texture from being achieved.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A smoothie maker with temperature detection function includes a body, on which a drive assembly and a refrigeration assembly are mounted; an ice bucket assembly, which includes a water tank and an evaporator. The water tank is mounted on the body and has an ice-making chamber formed inside, which has a liquid inlet and an ice outlet. The evaporator is located inside the ice-making chamber and has an evaporation chamber formed inside, which has an air inlet pipe and an air outlet pipe. The air inlet pipe is connected to the output end of the refrigeration assembly, and the air outlet pipe is connected to the input end of the refrigeration assembly. A stirring assembly is movably mounted on the evaporator and is driven to rotate by the drive assembly. A temperature sensor is fixed on the evaporator and is positioned corresponding to the ice outlet. With this setup, during ice making, a certain amount of liquid is poured into the ice-making chamber of the water tank through the inlet, ensuring the liquid level is at least higher than the temperature sensor. During operation, the refrigeration unit introduces refrigerant into the evaporation chamber to cool the liquid. The drive unit rotates the stirring component, continuously agitating the liquid to improve ice-making efficiency. The temperature sensor monitors the liquid temperature in real time. When the temperature reaches a preset value, refrigeration stops, and the stirring component continues to rotate, pushing the slush out through the ice outlet. After a period of time, the liquid in the water tank gradually heats up. When the temperature sensor detects a temperature higher than the preset value, ice making restarts, and the cycle repeats. Fixing the temperature sensor to the evaporator and aligning it with the ice outlet allows for more accurate temperature detection at the outlet, ensuring the slush temperature remains within a certain range. This guarantees normal ice dispensing, preventing both excessively high temperatures that melt the slush and excessively low temperatures that cause the slush to become large or too hard, clogging the outlet and hindering dispensing, ultimately preventing the desired slush texture from being achieved.

[0008] According to the above scheme, the evaporator is a circular tube with a cap at one end and an opening at the second end, and the temperature sensor is fixed on the cap. The inlet pipe and outlet pipe are opposite and symmetrically located on the inner circle of the circular tube near the opening. This arrangement facilitates assembly, makes reasonable use of the evaporator's installation space, and prevents the temperature sensor from interfering with the inlet and outlet pipes during assembly. The inlet and outlet pipes extend from the opening and are connected to the refrigeration assembly; the temperature sensor's wire extends from the opening and is connected to the controller on the unit body.

[0009] According to the above scheme, a first mounting hole is provided through the cover, and the temperature sensor is installed inside the first mounting hole. The first end of the temperature sensor is located outside the evaporator and is in close contact with the outer wall of the cover. The second end of the temperature sensor passes through the first mounting hole and is located inside the evaporator. A sealing gasket and a fixing member are fitted onto the second end of the temperature sensor, and the sealing gasket is tightly attached to the inner wall of the cover through the fixing member. With this configuration, the temperature sensor is installed through the first mounting hole, wherein the first end of the temperature sensor is exposed outside the evaporator, and the second end of the temperature sensor is located inside the evaporator; wherein the first end of the temperature sensor is in close contact with the outer wall of the cover, and the second end of the temperature sensor is fitted with a sealing gasket, and the sealing gasket is tightly attached to the inner wall of the cover, ensuring a reliable seal and preventing liquid from entering the evaporator; wherein the second end of the temperature sensor is formed with an external thread, and the fixing member is a nut, the internal thread on the fixing member is threadedly connected to the external thread, and screwed to restrict the sealing gasket to be tightly attached to the inner wall of the cover.

[0010] According to the above scheme, a first mounting hole is provided through the cap, and the temperature sensor is inserted into the first mounting hole. The first end of the temperature sensor is located outside the evaporator, and a cap is wrapped around the first end of the temperature sensor. The cap is tightly fixed to the outer wall of the cap, and the second end of the temperature sensor passes through the first mounting hole and is located inside the evaporator. This arrangement hides the temperature sensor inside the evaporator, preventing it from contacting the liquid, and also results in a more aesthetically pleasing and simple appearance. The cap is welded to the cap and seals the first mounting hole.

[0011] According to the above scheme, the cap is formed with a raised bump, and the temperature sensor is located inside the evaporator, with the first end of the temperature sensor tightly attached to the inner wall of the raised bump. This design hides the temperature sensor inside the evaporator 30, preventing it from contacting the liquid, and also results in a more aesthetically pleasing and streamlined appearance. The raised bump helps position the temperature sensor, ensuring it is correctly attached to the inside of the cap.

[0012] According to the above scheme, a limiting ring is fixed on the inner wall of the cover, and the limiting ring is located in a ring shape on the outer periphery of the sealing gasket. This arrangement limits the outer periphery of the sealing gasket by the limiting ring, preventing the sealing gasket from extending outwards when deformed under force, thereby ensuring the sealing reliability of the sealing gasket. The limiting ring is slightly larger than the sealing gasket and can completely encircle the outer periphery of the sealing gasket.

[0013] According to the above scheme, the evaporation chamber is located in a ring shape on the inner or outer circle of a circular tube, and the circular tube is filled with insulation material. This arrangement increases the contact area between the evaporation chamber and the liquid, thereby improving the refrigeration efficiency. The insulation material inside the circular tube enhances the insulation effect of the evaporator.

[0014] According to the above scheme, the stirring assembly includes a stirring rod and a drive shaft. The stirring rod is located in a ring shape on the outer circumference of the circular tube. The first end of the drive shaft is fixedly connected to the stirring rod, and the second end of the drive shaft passes through the evaporator and is connected to the output end of the drive assembly. With this configuration, during stirring, the drive assembly drives the drive shaft to rotate the stirring rod, stirring the liquid and simultaneously scraping off the ice sand formed on the outer circumference of the circular tube and pushing it to the ice outlet.

[0015] According to the above scheme, the cover is provided with a second mounting hole; the evaporator is provided with a drive shaft mounting component, the first end of the drive shaft mounting component is provided with a mounting seat, the mounting seat is located inside the second mounting hole, the mounting seat is provided with a first bushing, and the first bushing is provided with a first bearing; the second end of the drive shaft mounting component is provided with a second bushing, and the second bushing is provided with a second bearing; the second end of the drive shaft passes through the first bearing, the drive shaft mounting component and the second bearing in sequence and is connected to the output end of the drive assembly. This configuration, under the action of the drive shaft mounting component, restricts the radial movement of the drive shaft, and with the cooperation of the bushing and bearing, reduces the friction of the drive shaft, resulting in smoother rotation.

[0016] According to the above scheme, a first sealing ring and a second sealing ring are fixed on the drive shaft near the first bearing. The first sealing ring is sealed to the first shaft sleeve, and the second sealing ring is located between the first sealing ring and the first bearing. A baffle is fixed on the drive shaft near the second bearing, and the baffle abuts against the second bearing. This arrangement, with the action of the double sealing rings, ensures reliable sealing and prevents liquid from entering the evaporator. The baffle restricts the axial movement of the drive shaft, thus preventing the stirring rod from moving axially. Specifically, it prevents the drive shaft from moving forward, which would cause the stirring rod to move forward as well, resulting in interference with the water tank.

[0017] The beneficial effects of this utility model are:

[0018] This invention features a temperature sensor fixed to the evaporator and positioned corresponding to the ice outlet. This allows for more accurate detection of the temperature at the ice outlet, ensuring that the temperature of the ice slush at the outlet remains within a certain range. This guarantees normal ice dispensing, preventing both excessively high temperatures at the outlet that would cause the ice slush to melt and excessively low temperatures that would cause the ice slush to become large or too hard, clogging the outlet and hindering dispensing, ultimately preventing the desired ice slush shape from being achieved.

[0030] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0031] Example 1:

[0032] like Figures 1 to 7As shown, the present invention discloses a smoothie maker with temperature detection function, comprising a body 1, on which a drive assembly 3 and a refrigeration assembly are provided; an ice bucket assembly 2, comprising a water tank 10 and an evaporator 30, the water tank 10 being mounted on the body 1, and an ice-making chamber 4 formed therein, the ice-making chamber 4 having a liquid inlet 11 and an ice outlet 12; the evaporator 30 being disposed within the ice-making chamber 4, the evaporator 30 having an evaporation chamber 5 formed therein, the evaporation chamber 5 having an air inlet pipe 310 and an air outlet pipe 311, the air inlet pipe 310 being connected to the output end of the refrigeration assembly, and the air outlet pipe 311 being connected to the input end of the refrigeration assembly; a stirring assembly being movably mounted on the evaporator 30, the stirring assembly being driven to rotate by the drive assembly 3; and a temperature sensor 40 being fixed on the evaporator 30, the temperature sensor 40 being correspondingly arranged with the ice outlet 12. With this setup, during ice making, a certain amount of liquid is poured into the ice-making chamber 4 of the water tank 10 through the liquid inlet 11, and the amount of liquid must be at least higher than the temperature sensor 40. During operation, the refrigeration component introduces refrigerant into the evaporation chamber 5 to cool the liquid. The drive component 3 drives the stirring component to rotate, continuously stirring the liquid to improve ice-making efficiency. The temperature sensor 40 detects the liquid temperature in real time. When the temperature reaches the preset value, refrigeration stops, and the stirring component continues to rotate, pushing the ice slush out through the ice outlet 12. After a period of time, the liquid in the water tank 10 will gradually heat up. When the temperature sensor 40 detects that the temperature is higher than the preset value by a certain amount, ice making restarts, and the cycle continues. The temperature sensor 40 is fixed to the evaporator 30 and correspondingly positioned to the ice outlet 12. This allows for more accurate detection of the temperature at the ice outlet 12, ensuring that the temperature of the ice slush at the outlet 12 remains within a certain range. This guarantees normal ice dispensing, preventing both excessively high temperatures at the outlet 12 that would cause the ice slush to melt and excessively low temperatures that would cause the ice slush to become large or too hard, clogging the outlet and hindering dispensing, ultimately preventing the desired ice slush texture from being achieved. The drive component 3 is a motor, and the refrigeration components include a compressor, a condenser, and a capillary tube.

[0033] Furthermore, the evaporator 30 is a circular tube with a cap 32 at one end and an opening 31 at the other end, and the temperature sensor 40 is fixed to the cap 32; the inlet pipe 310 and the outlet pipe 311 are symmetrically located on the inner circle of the circular tube near the opening 31. This arrangement facilitates assembly, makes reasonable use of the installation space of the evaporator 30, and ensures that the temperature sensor 40 will not interfere with the inlet pipe 310 and the outlet pipe 311 during assembly. The inlet pipe 310 and the outlet pipe 311 extend out of the opening 31 and are connected to the refrigeration assembly; the wire of the temperature sensor 40 extends out of the opening 31 and is connected to the controller on the main body 1.

[0034] Furthermore, the cover 32 is provided with a first mounting hole 38, and the temperature sensor 40 is installed inside the first mounting hole 38. The first end of the temperature sensor 40 is located outside the evaporator 30 and is in close contact with the outer wall of the cover 32. The second end of the temperature sensor 40 passes through the first mounting hole 38 and is located inside the evaporator 30. The second end of the temperature sensor 40 is fitted with a sealing gasket 41 and a fixing member 43. The sealing gasket 41 is in close contact with the inner wall of the cover 32 through the fixing member 43. With this configuration, the temperature sensor 40 is installed through the first mounting hole 38, with the first end of the temperature sensor 40 exposed on the outside of the evaporator 30 and the second end of the temperature sensor 40 located inside the evaporator 30. The first end of the temperature sensor 40 is in close contact with the outer wall of the cover 32, and the second end of the temperature sensor 40 is fitted with a sealing gasket 41, which is in close contact with the inner wall of the cover 32, ensuring a reliable seal and preventing liquid from entering the evaporator 30. The second end of the temperature sensor 40 has an external thread, and the fixing member 43 is a nut. The internal thread on the fixing member 43 is threaded to the external thread, and screwed to restrict the sealing gasket 41 to be in close contact with the inner wall of the cover 32.

[0035] Furthermore, a limiting ring 42 is fixed on the inner wall of the cover 32, and the limiting ring 42 is located in a ring shape on the outer periphery of the sealing gasket 41. This arrangement limits the outer periphery of the sealing gasket 41 by the limiting ring 42, preventing the sealing gasket 41 from extending outwards when deformed under force, thereby ensuring the sealing reliability of the sealing gasket 41. The limiting ring 42 is slightly larger than the sealing gasket 41 and can completely encircle the outer periphery of the sealing gasket 41.

[0036] Furthermore, the evaporation chamber 5 is located in a ring shape on the inner or outer circumference of the circular tube, and the circular tube is filled with insulation material. This arrangement increases the contact area between the evaporation chamber 5 and the liquid, thereby improving the refrigeration efficiency. The insulation material inside the circular tube enhances the insulation effect of the evaporator 30.

[0037] Furthermore, the stirring assembly includes a stirring rod 20 and a drive shaft 21. The stirring rod 20 is located in a ring shape on the outer circumference of the circular tube. The first end of the drive shaft 21 is fixedly connected to the stirring rod 20, and the second end of the drive shaft 21 passes through the evaporator 30 and is connected to the output end of the drive assembly 3. With this configuration, during stirring, the drive assembly 3 drives the drive shaft 21 to rotate the stirring rod 20, stirring the liquid and simultaneously scraping off the ice shavings formed on the outer circumference of the circular tube and pushing them to the ice outlet 12.

[0038] Furthermore, the cover 32 is provided with a second mounting hole 39; the evaporator 30 is provided with a drive shaft mounting component 33, the first end of the drive shaft mounting component 33 is provided with a mounting seat 37, the mounting seat 37 is located inside the second mounting hole 39, the mounting seat 37 is provided with a first bushing 34, and the first bushing 34 is provided with a first bearing 22; the second end of the drive shaft mounting component 33 is provided with a second bushing 36, and the second bushing 36 is provided with a second bearing 23; the second end of the drive shaft 21 passes through the first bearing 22, the drive shaft mounting component 33 and the second bearing 23 in sequence and is connected to the output end of the drive assembly 3. This configuration, under the action of the drive shaft mounting component 33, restricts the radial movement of the drive shaft 21, and with the cooperation of the bushing and bearing, reduces the friction of the drive shaft 21, resulting in smoother rotation.

[0039] Furthermore, a first sealing ring 312 and a second sealing ring 313 are fixed on the drive shaft 21 near the first bearing 22. The first sealing ring 312 is sealed to the first bushing 34, and the second sealing ring 313 is located between the first sealing ring 312 and the first bearing 22. A baffle 35 is fixed on the drive shaft 21 near the second bearing 23, and the baffle 35 abuts against the second bearing 23. With this arrangement, the double sealing rings provide a reliable seal, preventing liquid from entering the evaporator 30. The baffle 35 restricts the axial movement of the drive shaft 21, thereby preventing the stirring rod 20 from moving axially. Specifically, it prevents the drive shaft 21 from moving forward, which would cause the stirring rod 20 to move forward as well, resulting in interference with the water tank 10.

[0040] Example 2:

[0041] like Figure 8 As shown, a first mounting hole 38 is provided through the cover 32, and the temperature sensor 40 is inserted into the first mounting hole 38. The first end of the temperature sensor 40 is located outside the evaporator 30, and a cap 50 is wrapped around the first end of the temperature sensor 40. The cap 50 is tightly fixed to the outer wall of the cover 32. The second end of the temperature sensor 40 passes through the first mounting hole 38 and is located inside the evaporator 30. This arrangement hides the temperature sensor 40 inside the evaporator 30, preventing it from contacting the liquid, and also results in a more aesthetically pleasing and simple appearance. The cap 50 is welded to the cover 32 and seals the first mounting hole 38.

[0042] The difference between this second embodiment and the first embodiment lies in the assembly method of the temperature sensor 40. The rest of the structure and principle are the same as those in the first embodiment, and will not be repeated.

[0043] Example 3:

[0044] like Figure 9As shown, a protrusion 60 is formed on the cover 32, and the temperature sensor 40 is located inside the evaporator 30, with the first end of the temperature sensor 40 tightly attached to the inner wall of the protrusion 60. This arrangement hides the temperature sensor 40 inside the evaporator 30, preventing it from contacting the liquid, and also results in a more aesthetically pleasing and streamlined appearance. The protrusion 60 helps position the temperature sensor 40, ensuring it is correctly attached to the inside of the cover 32.

[0045] The difference between this embodiment 3 and embodiment 1 is that the assembly method of the temperature sensor 40 is different. The rest of the structure and principle are the same as those of embodiment 1, and will not be repeated.
