Description

Technical Field

[0001] The invention relates to an ice smoothie machine, in particular to a direct-injection refrigeration type ice smoothie machine. Background Art

[0002] At present, ice machines generally use compression refrigeration to cool water to freeze it, then crush the ice, and finally output it. The form of compression refrigeration is to connect the compressor, condenser, dry filter, capillary tube and evaporator in series to form a refrigeration cycle, and surround the evaporator on the outer wall of the ice bucket. In this way, when the compressor is working, the liquid refrigerant in the evaporator can evaporate and absorb heat to take away the heat in the ice bucket, so that the water in the ice bucket freezes.

[0003] However, under this cooling method, the heat in the water needs to pass through the ice bucket and the evaporator in turn before it can be absorbed by the refrigerant. The long heat conduction path leads to low heat conduction efficiency, which directly reduces the efficiency of ice making.

[0004] In addition, this refrigeration structure requires a lot of time to wrap the metal pipe around the outer wall of the ice bucket as an evaporator during the production process, which has extremely low production efficiency, and the winding quality will also have a great impact on the refrigeration efficiency.

[0005] Therefore, how to overcome the above-mentioned defects has become an important issue to be solved urgently by those skilled in the art. Summary of the invention

[0027] The features of the present invention and other related features are further described in detail below through embodiments to facilitate understanding by those skilled in the art:

[0028] like Figures 1 to 7As shown, a direct-injection refrigeration ice smoothie machine includes a frame 1, an ice bucket 2 and a compression refrigeration component 3 are fixed on the frame 1, an ice making chamber 22 is arranged in the ice bucket 2, the compression refrigeration component 3 includes an evaporation chamber 31 formed between the outer shell of the ice bucket 2 and the ice making chamber 22, the evaporation chamber 31 is connected in series in the compression refrigeration component 3, and the refrigerant of the compression refrigeration component 3 is directly sprayed into the evaporation chamber 31 for evaporation and heat absorption refrigeration, a water injection port 4 for adding water to the ice bucket 2 is provided at the upper front end portion of the ice bucket 2, and an openable and closable ice outlet 5 is provided at the lower front end portion, the water injection port 4 and the ice outlet 5 are both connected to the ice making chamber 22, and an ice crushing and discharging integrated component 6 for crushing ice and conveying ice to the ice outlet 5 is also fixed on the ice bucket 2.

[0029] The direct-injection refrigeration ice smoothie machine of this case is provided with an evaporation chamber 31 in the ice making bucket 2, and the evaporation chamber 31 is connected in series in the compression refrigeration component 3 to replace the position of the evaporator. After the low-temperature and low-pressure liquid refrigerant processed by the compression refrigeration component 3 enters the evaporation chamber 31, it absorbs heat and evaporates into a gaseous state in the evaporation chamber 31, thereby cooling the ice making chamber 22, and then continues to circulate in the compression refrigeration component 3. When the water in the ice making chamber 22 freezes at low temperature, the ice crushing and discharging integrated component 6 can be controlled to crush the ice condensed in the ice making chamber 22, and the ice crushing and discharging integrated component 6 will push the ice cubes to the ice outlet 5 while crushing the ice cubes so as to output the ice cubes to the outside for users to use.

[0030] As described above, the ice smoothie machine of this case connects the evaporation chamber 31 in the ice bucket 2 in series with the compression refrigeration assembly 3 so that the refrigerant can directly evaporate and absorb heat in the ice bucket 2 without going through layers of heat conduction. After the heat conduction path is simplified, the efficiency of heat exchange can be greatly improved, so that the ice making efficiency can also be greatly improved, and energy consumption can also be reduced. In addition, since the ice smoothie machine of this case uses the evaporation chamber 31 to replace the traditional evaporator, the complex process of winding the metal pipe on the outer wall of the ice chamber 22 is omitted, which greatly simplifies the production process, improves production efficiency, and avoids the problem of affecting the refrigeration effect due to improper winding.

[0031] like Figure 2 and 3 As shown, preferably, the compression refrigeration assembly 3 also includes a compressor 32, a condenser 33, a drying filter 34 and a capillary tube 35 fixed at the lower part of the frame 1. The compressor 32, the condenser 33, the drying filter 34, the capillary tube 35 and the evaporation chamber 31 are connected in an end-to-end cycle in sequence to form a refrigeration cycle. In this way, the refrigerant can be driven to operate continuously through the refrigeration cycle, so that the refrigerant continuously absorbs heat and evaporates in the evaporation chamber 31 for refrigeration.

[0032] Specifically, the evaporation chamber 31 is provided with a refrigerant inlet 313 connected to the capillary tube 35 and a refrigerant outlet 314 connected to the compressor 32, so that the low-temperature and low-pressure liquid refrigerant output from the end of the capillary tube 35 can enter the evaporation chamber 31 through the refrigerant inlet 313, and the low-temperature and low-pressure gaseous refrigerant formed after endothermic evaporation can re-enter the compressor 32 from the refrigerant outlet 314 for the next round of compression.

[0033] like Figures 4 to 6 As shown, preferably, the refrigerant inlet 313 of the evaporation chamber 31 is connected with a nozzle 311 extending into the evaporation chamber 31 , and the nozzle 311 is provided with a plurality of spray holes 312 facing the outer wall of the ice-making chamber 22 .

[0034] As described above, after entering the evaporation chamber 31, the low-temperature and low-pressure liquid refrigerant does not diffuse freely to the surroundings but enters the nozzle 311, and the nozzle 311 is provided with a spray hole 312 facing the outer wall of the ice-making chamber 22. In this way, it can be ensured that the refrigerant will be sprayed onto the surface of the evaporation chamber 31 close to the ice-making chamber 22 under subsequent pressure and absorb heat and evaporate thereon, thereby ensuring that the evaporation of the refrigerant can effectively cool the ice-making chamber 22 and cause the water therein to freeze.

[0035] like Figures 4 to 7 As shown, preferably, the ice crushing and discharging integrated assembly 6 includes a driving motor 61 fixed to the rear end of the outer side of the ice bucket 2 and a scraper 62 located in the ice making chamber 22 and coaxially arranged with the ice bucket 2. The driving motor 61 is driven and connected to the scraper 62 to drive the scraper 62 to rotate in the ice making chamber 22. The scraper 62 is provided with a scraping blade 621 that extends spirally around the axis of the ice bucket 2.

[0036] As described above, the ice-crushing and discharging integrated assembly 6 in the present case includes a driving motor 61 and a scraper 62, and the scraper 62 is provided with a spirally extending scraping blade 621, so that when the driving motor 61 drives the scraper 62 to rotate, the scraping blade 621 can crush the ice cubes. At the same time, since the scraping blade 621 is spirally extended, the crushed ice can be gradually pushed to the ice outlet while crushing the ice cubes, thereby completing ice crushing and ice discharging simultaneously.

[0037] like Figure 6 and Figure 7 As shown, preferably, a rotating seat 63 is also provided at the front end of the inner cavity of the ice bucket 2 for the front end of the scraper 62 to be inserted thereon and rotated so as to support the scraper 62. In this way, the rear end of the scraper 62 is connected to the drive motor 61 and is driven to rotate by the drive motor 61, while the front end of the scraper 62 can be fixed on the rotating seat 63 and rotated. In this way, the front and rear forces of the scraper 62 can be balanced when rotating, thereby preventing the scraper 62 from tilting during the ice crushing process, affecting the quality of the ice crushing and reducing the life of the scraper 62.

[0038] like Figures 2 to 7 As shown, preferably, the ice bucket 2 includes a shell 21 fixed on the frame 1, the ice making chamber 22 is located in the shell 21 and opens forward, the evaporation chamber 31 is located outside the wall of the ice making chamber 22, and the front end of the shell 21 is also detachably connected with an end cover 23 for sealing the opening of the ice making chamber 22, the water injection port 4 is arranged at the upper part of the end cover 23, and the ice outlet 5 is arranged at the lower part of the end cover 23, so that the evaporation chamber 31 can be protected by the shell 21 to avoid damage to the evaporation chamber 31 due to external impact and failure of the refrigeration cycle. At the same time, using a detachable end cover 23 to seal the ice making chamber 22 can also facilitate opening the end cover 23 to clean the inside of the ice bucket 2 after long-term use.

[0039] Specifically, the rotating seat 63 is rotatably connected to the end cover 23 .

[0040] Preferably, the ice-making chamber 22 is made of stainless steel.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, preferably, the front end of the ice bucket 2 is hinged with a first sealing cover 24 that can rotate to open / block the ice outlet 5, and the ice bucket 2 is also hinged with a handle 25 for driving the first sealing cover 24 to rotate, and the handle 25 and the first sealing cover 24 are transmission-connected by a connecting rod structure, and a reset torsion spring 26 for driving the first sealing cover 24 to close and reset is also provided at the hinge of the first sealing cover 24, so that when there is no need to discharge ice, the reset torsion spring 26 can provide the first sealing cover 24 with a tendency to rotate and close, ensuring that the first sealing cover 24 can block the ice outlet 5 to prevent water leakage, and when the ice outlet 5 needs to be opened to discharge ice, the handle 25 can be rotated to make the first sealing cover 24 rotate and open under the transmission of the connecting rod structure to overcome the elastic force of the reset torsion spring 26.

[0042] Specifically, the first sealing cover 24 , the handle 25 , the connecting rod structure and the return torsion spring 26 are all connected to the end cover 23 .

[0043] like Figure 1 As shown, preferably, the ice bucket 2 is also provided with a second sealing cover 27 that can slide forward and backward. The second sealing cover 27 slides forward to cover the water injection port 4 and slides backward to expose the water injection port 4. In this way, when it is not necessary to add water to the ice bucket 2, the second sealing cover 27 can be slid to cover the water injection port 4 to prevent foreign matter from entering the ice bucket 2 and causing pollution. The water injection port 4 is only exposed when water needs to be added. At the same time, when making ice, covering the water injection port 4 with the second sealing cover 27 can also prevent external heat from directly entering the ice bucket 2 through the water injection port 4 to reduce the ice making efficiency.

[0044] As mentioned above, this case protects a direct-injection refrigeration smoothie machine, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
