Description

Technical Field

[0001] This utility model relates to a smoothie machine. Background Technology

[0002] Currently, smoothie makers generally use compression refrigeration to cool water until it freezes, then crushes the ice before dispensing it. Compression refrigeration involves connecting a compressor, condenser, dryer filter, capillary tube, and evaporator in series to form a refrigeration cycle. The evaporator typically consists of evaporator tubes wound around the outer wall of the ice maker. Although the evaporator tubes are wound around the ice maker, because commonly used evaporator tubes are round, the contact between the evaporator tubes and the ice maker is only a line-to-surface contact. The actual contact area between the evaporator tubes and the ice maker is only a very small fraction of the evaporator tube's surface area, resulting in extremely low heat transfer efficiency and hindering ice-making efficiency.

[0003] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0004] This invention overcomes the shortcomings of the above-mentioned technology and provides a smoothie machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smoothie machine includes a frame 1, on which an ice-making bucket 2 and a compression refrigeration assembly 3 are fixed. The ice-making bucket 2 has an ice-making chamber 21 inside. The compression refrigeration assembly 3 includes an evaporation tube 31 wound around the wall of the ice-making bucket 2. After the evaporation tube 31 is wound around the ice-making bucket 2, it forms a cylindrical surface with an inner diameter the same as the outer diameter of the ice-making bucket 2 to facilitate surface-to-surface contact with the ice-making bucket 2. Both the evaporation tube 31 and the surface of the ice-making bucket 2 are provided with a semi-solid thermally conductive coating. The upper front end of the ice-making bucket 2 is provided with a water inlet 4 for adding water into the ice-making bucket 2, and the lower front end is provided with an openable ice outlet 5. Both the water inlet 4 and the ice outlet 5 are connected to the ice-making chamber 21. An integrated ice crushing and discharging assembly for crushing ice and conveying ice to the ice outlet 5 is also fixed on the ice-making bucket 2.

[0008] Preferably, the semi-solid thermally conductive coating on the surface of the evaporator tube 31 and the ice bucket 2 is thermally conductive silicone grease.

[0009] Preferably, the compression refrigeration assembly 3 further includes a compressor 32, a condenser 33, a dryer filter 34, and a capillary tube 35 fixed to the lower part of the frame 1.

[0010] Preferably, the integrated ice crushing assembly includes a drive motor 61 fixed to the rear of the outside of the ice-making bucket 2 and a scraper 62 located inside the ice-making chamber 21 and coaxially arranged with the ice-making bucket 2.

The scraper 62 is provided with a scraping blade 621 that extends spirally around the axis of the ice-making bucket 2.

[0011] Preferably, the front end of the ice bucket 2 is also provided with a rotating seat 64 for the front end of the scraper 62 to be inserted and rotated so as to support the scraper 62.

[0012] Preferably, the ice bucket 2 includes a housing 22 fixed on the frame 1, the ice-making chamber 21 is located inside the housing 22 with its opening facing forward, and the front end of the housing 22 is also detachably connected to an end cap 23 for sealing the opening of the ice-making chamber 21, the water inlet 4 is located on the upper part of the end cap 23, and the ice outlet 5 is located on the lower part of the end cap 23.

[0013] Preferably, the ice-making cavity 21 is made of stainless steel.

[0023] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0024] like Figures 1 to 5 As shown, a smoothie machine includes a frame 1, on which an ice-making bucket 2 and a compression refrigeration assembly 3 are fixed. The ice-making bucket 2 has an ice-making chamber 21 inside. The compression refrigeration assembly 3 includes an evaporator tube 31 wound around the wall of the ice-making bucket 2. After the evaporator tube 31 is wound around the ice-making bucket 2, it forms a cylindrical surface with an inner diameter the same as the outer diameter of the ice-making bucket 2 to facilitate surface-to-surface contact with the ice-making bucket 2. Both the evaporator tube 31 and the surface of the ice-making bucket 2 are provided with a semi-solid thermally conductive coating. The upper front end of the ice-making bucket 2 is provided with a water inlet 4 for adding water into the ice-making bucket 2, and the lower front end is provided with an openable ice outlet 5. Both the water inlet 4 and the ice outlet 5 are connected to the ice-making chamber 21. An integrated ice crushing and discharging assembly for crushing ice and conveying ice to the ice outlet 5 is also fixed on the ice-making bucket 2.

[0025] The evaporator tube 31 used in this slush machine, after being wound around the ice-making bucket 2, forms a cylindrical surface with an inner diameter identical to the outer diameter of the ice-making bucket 2. This changes the contact method between the evaporator tube 31 and the ice-making bucket 2 from the traditional line-to-surface contact scheme with extremely low thermal conductivity to a surface-to-surface contact scheme with higher thermal conductivity, significantly improving the efficiency of heat transfer between the evaporator tube 31 and the ice-making bucket 2, thereby increasing ice-making efficiency. Furthermore, this slush machine also features a semi-solid thermally conductive coating on the surfaces of the evaporator tube 31 and the ice-making bucket 2. This semi-solid thermally conductive coating better fills the gaps between the evaporator tube 31 and the ice-making bucket 2, further improving the thermal conductivity of the evaporator tube 31 and the ice-making bucket 2 and reducing cold loss.

[0026] To improve ice-making efficiency, and to ensure that ice dispensing efficiency matches ice-making efficiency, this slush machine also has an integrated ice crushing and dispensing component fixed on the ice bucket 2 for crushing ice and conveying ice to the ice outlet 5. When the water in the ice-making chamber 21 freezes at a low temperature, the integrated ice crushing and dispensing component can be controlled to crush the ice frozen in the ice-making chamber 21. While crushing the ice, the component also pushes the crushed ice towards the ice outlet 5 for easy dispensing to the user. This combination of crushing and dispensing effectively improves ice dispensing efficiency.

[0027] As described above, the slush machine of this invention improves the heat transfer efficiency between the evaporator tube 31 and the ice-making bucket 2 by changing the contact form between the evaporator tube 31 and the ice-making bucket 2, and by applying a semi-solid thermally conductive coating to both surfaces. This solves the problem of low heat transfer efficiency between the evaporator tube 31 and the ice-making bucket 2 in traditional structures, thus improving ice-making efficiency. Simultaneously, the slush machine of this invention also incorporates an integrated ice-crushing and dispensing component on the ice-making bucket 2. By synchronizing the ice-crushing and dispensing actions, the ice-dispensing efficiency can be effectively improved, allowing it to match the ice-making efficiency and preventing ice from accumulating in the ice-making chamber 21.

[0028] like Figure 4 As shown, preferably, the cross-sectional shape of the evaporator tube 31 is an elliptical racetrack shape with parallel straight lines on the top and bottom sides and semicircles on the left and right ends. This allows the straight edges near the surface of the ice bucket 2 to form a cylindrical surface that fits snugly against the surface of the ice bucket 2 when the evaporator tube 31 is wound around it, thus significantly increasing the contact area between the evaporator tube 31 and the ice bucket 2 and improving heat transfer efficiency. Furthermore, the overall elliptical racetrack shape of the evaporator tube 31 cross-section reduces stress concentration on the side of the evaporator tube 31 furthest from the ice bucket 2 during winding, minimizing damage to the evaporator tube 31 caused by winding and bending.

[0029] Preferably, the semi-solid thermally conductive coating on the surface of the evaporator tube 31 and the ice bucket 2 is thermally conductive silicone grease. In this way, by applying thermally conductive silicone grease to the surface of the evaporator tube 31 and the ice bucket 2 to form a semi-solid thermally conductive coating, when the evaporator tube 31 is wrapped around the ice bucket 2, the thermally conductive silicone grease will be squeezed into the gap between the two and fill the gap, thereby further improving the heat transfer efficiency between the evaporator tube 31 and the ice bucket 2.

[0030] like Figure 2 and Figure 3As shown, preferably, the compression refrigeration assembly 3 further includes a compressor 32, a condenser 33, a dryer filter 34, and a capillary tube 35 fixed to the lower part of the frame 1. The compressor 32, condenser 33, dryer filter 34, capillary tube 35, and evaporator tube 31 are connected end to end in a refrigeration cycle. In this way, the refrigerant can be driven to operate continuously through the refrigeration cycle, so that the refrigerant continuously evaporates and absorbs heat at the evaporator tube 31 to cool down.

[0031] like Figures 3 to 5 As shown, preferably, the integrated ice crushing assembly includes a drive motor 61 fixed to the rear of the outside of the ice-making bucket 2 and a scraper 62 located inside the ice-making chamber 21 and coaxially arranged with the ice-making bucket 2. The drive motor 61 is driven to the scraper 62 through a reduction gear set 63 so as to drive the scraper 62 to rotate inside the ice-making chamber 21. The scraper 62 is provided with a scraping blade 621 that extends spirally around the axis of the ice-making bucket 2.

[0032] As described above, the integrated ice-crushing assembly of this invention includes a drive motor 61 and a scraper 62. The drive motor 61 and the scraper 62 are connected by a reduction gear set 63. The scraper 62 is provided with a spirally extending scraping blade 621. Thus, the drive motor 61 drives the scraper 62 to rotate. When the scraper 62 rotates, it can crush the ice through the scraping blade 621. At the same time, since the scraping blade 621 is spirally extended, it can also gradually push the crushed ice towards the ice outlet 5. Moreover, since the drive motor 61 is connected to the scraper 62 by the reduction gear set 63, the reduction gear set 63 can effectively increase the rotational torque of the scraper 62, improve the ice-crushing ability, and prevent the scraper 62 from freezing when water freezes.

[0033] like Figure 4 As shown, preferably, the front end of the ice-making bucket 2 is also provided with a rotating seat 64 for the front end of the scraper 62 to be inserted and rotated to support the scraper 62. In this way, the rear end of the scraper 62 is connected to the reduction gear set 63 and driven by the drive motor 61, while the front end of the scraper 62 can be fixed on the rotating seat 64 to rotate. This allows the scraper 62 to maintain a balance of force at both ends when rotating, and avoids the scraper 62 from tilting during the ice crushing process, which would affect the ice crushing quality and reduce the life of the scraper 62.

[0034] like Figures 2 to 5 As shown, preferably, the ice bucket 2 includes a housing 22 fixed on the frame 1, and the ice-making cavity 21 is located inside the housing 22 with its opening facing forward. The front end of the housing 22 is also detachably connected to an end cap 23 for sealing the opening of the ice-making cavity 21. The water inlet 4 is located on the upper part of the end cap 23 and the ice outlet 5 is located on the lower part of the end cap 23. In this way, by using the detachable end cap 23 to seal the ice-making cavity 21, the interior of the ice bucket 2 can be cleaned and repaired by disassembling the ice-making cavity 21 after long-term use of the ice maker.

[0035] Specifically, the rotating seat 64 is rotatably connected to the end cover 23.

[0036] Preferably, the ice-making cavity 21 is made of stainless steel.

[0037] like Figure 4 and Figure 5 As shown, preferably, the front end of the ice bucket 2 is internally limited by a sealing bolt 24 that can move up and down. The sealing bolt 24 is used to move down to block the ice outlet 5 and move up to open the ice outlet 5. The ice bucket 2 is provided with a return spring 25 for driving the sealing bolt 24 to move down and reset. The ice bucket 2 is also hinged with a handle 26 for rotating and prying the sealing bolt 24 to move up. In this way, when ice is not needed, the return spring 25 can provide the sealing bolt 24 with the downward resetting motion so that the sealing bolt 24 can effectively block the ice outlet 5 and prevent water leakage at the ice outlet 5. When it is necessary to open the ice outlet 5 to let ice out, the sealing bolt 24 can be lifted by rotating the handle 26 to open the ice outlet 5 and allow crushed ice to be output from the ice outlet 5.

[0038] Specifically, the sealing bolt 24, the return spring 25, and the handle 26 are all connected to the end cap 23.

[0039] like Figures 1 to 5 As shown, the ice bucket 2 is also hinged with a sealing cap 27 that can be flipped to open / close the water inlet 4. Thus, when water is not needed in the ice bucket 2, the sealing cap 27 can be rotated to seal the water inlet 4, preventing foreign objects from entering and contaminating the ice bucket 2. Water is only needed when water is required, at which point the sealing cap 27 is rotated to open the water inlet 4. Simultaneously, sealing the water inlet 4 with the sealing cap 27 during ice making also prevents external heat from directly entering the ice bucket 2 through the water inlet 4, thus reducing ice-making efficiency.

[0040] As stated above, this case protects a smoothie machine, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
