[0002] Snow melt machine is a beverage making equipment used in the catering industry. In the hot summer, people's demand for chilled drinks increases greatly. The existing snow melt machine is mainly composed of a beverage barrel and a refrigeration system. The evaporator cylinder of the refrigeration system is placed horizontally in the beverage barrel, and a spiral agitator is mounted outside the evaporator cylinder. A cover plate reduction motor that drives the agitator is installed at the rear of the evaporator cylinder.

When the strength of the spiral stirrer is not enough to stir materials with high viscosity such as ice cream, additional stirring blades are added to achieve this function. However, the more internal structures these snow melt machines have, the narrower the space is, and the smaller the area that can be cleaned becomes, which makes it difficult for operators to clean them later. In addition, hard ice that is difficult to stir often forms on the evaporator cylinder, causing certain damage to the spiral stirring blades. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example: Figure 1-Figure 9As shown, the present invention provides a technical solution, a snow melting machine with intelligent temperature control function, comprising a cabinet 1, a beverage barrel 2, an evaporator cylinder 3, a rear seat 4 and a spiral stirring blade 7, a refrigeration unit is arranged in the cabinet 1, the beverage barrel 2 and the rear seat 4 are arranged adjacent to each other on the cabinet 1, the evaporator cylinder 3 is arranged in the beverage barrel 2, the evaporator cylinder 3 is connected to the refrigeration unit pipeline, the spiral stirring blade 7 is rotatably installed on the outside of the evaporator cylinder 3, a sub-chassis 5 is arranged on the side of the rear seat 4 away from the beverage barrel 2, a stirring mechanism is arranged in the sub-chassis 5, a central axis 6 is arranged through the middle of the evaporator cylinder 3, one end of the central axis 6 is connected to the stirring mechanism, and the other end of the central axis 6 is connected to the spiral stirring blade 7, a temperature sensor is arranged inside the beverage barrel 2, the temperature sensor is connected to the control system through a circuit, a travel switch (not shown in the figure) is arranged inside the evaporator cylinder 3, a lever (not shown in the figure) is arranged on the central axis 6, and the lever is in contact with the travel switch.

[0028] An end connecting block 8 is provided at one end of the central axis 6 away from the stirring mechanism, and the spiral stirring blade 7 is connected to the end connecting block 8. A hollow water-filling ring 10 is sleeved and installed on one side of the central axis 6 close to the end connecting block 8. A high-pressure chamber is formed between the hollow water-filling ring 10 and the central axis 6. A water-filling pipe 11 is also connected to one side of the hollow water-filling ring 10, and a water pump (not shown in the figure) is connected to one side of the water-filling pipe 11. A plurality of water holes are opened on the central axis 6 between the high-pressure chamber and the spiral stirring blade 7. Each water hole passes through one end of the spiral stirring blade 7 and is sealed with a rubber plug 9. Each rubber plug 9 is in a cone shape, and a small spring (not shown in the figure) is connected between the small end of each rubber plug 9 and the spiral stirring blade 7. When the snow melting machine stops working, the operator first drains the beverage in the beverage barrel 2, and then the control system starts the water pump to start working, and the water pump pumps clean water into the high-pressure chamber through the water-filling pipe 11.

[0029] The small spring makes the rubber plug 9 seal in the water hole of the spiral stirring blade 7, and it will not fall off when the spiral stirring blade 7 rotates. Due to the cone-shaped setting of the rubber plug 9, the beverage will not flow back into the spiral stirring blade 7 through the rubber plug 9; the pressure of the clean water in each water hole in the high-pressure chamber increases, and the water pressure overcomes the tension applied to the rubber plug 9 by the small spring, and the clean water flushes the rubber plug 9 on the spiral stirring blade 7, and the clean water is sprayed onto the inner wall of the beverage barrel 2 for cleaning. The main motor 14 drives the spiral stirring blade 7 to rotate, and the clean water cleans the inner wall of the beverage barrel 2 in all directions. The clean water after cleaning is finally discharged from the water outlet of the beverage barrel 2. Through the setting of the hollow water filling ring 10 and the water opening hole of the spiral stirring blade 7, the snow melting machine is automatically cleaned, and the edges and corners that are difficult to clean are fully covered, eliminating the need for manual cleaning of the beverage barrel 2.

[0030] The stirring mechanism includes a main motor 14 and a spline shaft 12, the spline shaft 12 is connected to the main motor 14 through a motor shaft 13, an inner spline groove is provided at one end of the central shaft 6 close to the stirring mechanism, the spline shaft 12 is slidably connected to the inner spline groove, an adapter 21 is rotatably connected to one side of the central shaft 6 where the inner spline groove is provided, a round hole is provided on the top of the adapter 21, a limiting column 22 is provided at one end of the evaporator cylinder 3 close to the rear seat 4, the limiting column 22 is slidably connected in the round hole, an upper ratchet plate 23 is connected to one side of the adapter 21 away from the central shaft 6, a lower ratchet plate 24 is connected to the lower side of the upper ratchet plate 23 away from the adapter 21, and an upper Triangular ratchet grooves are provided on both sides of the ratchet plate 23 and the lower ratchet plate 24. The direction of the ratchet grooves on the upper ratchet plate 23 is opposite to that of the ratchet grooves on the lower ratchet plate 24. A swing mounting plate 25 is rotatably installed on the side of the rear seat 4 away from the evaporator tube 3 through a support plate. A gear 26 is coaxially connected to the top of the swing mounting plate 25. Two inner ratchet pawls 27 are symmetrically connected to the bottom of the swing mounting plate 25 near the upper ratchet plate 23, and two outer ratchet pawls 28 are symmetrically connected to the bottom of the swing mounting plate 25 near the lower ratchet plate 24. Coil springs are provided at the junctions of all the inner ratchet pawls 27 and the outer ratchet pawls 28 with the swing mounting plate 25.

[0031] The main motor 14 is energized to drive the spline shaft 12 to rotate, and the spline shaft 12 drives the middle shaft 6 to rotate through the inner spline groove. Since the spline shaft 12 is slidably connected to the middle shaft 6, the middle shaft 6 can rotate while sliding along the axial direction. The middle shaft 6 drives the end connecting block 8 to rotate, and the end connecting block 8 drives the spiral stirring blade 7 to rotate on the surface of the evaporator tube 3 to prevent the beverage from freezing after the evaporator tube 3 is frozen. When the swing mounting plate 25 swings, the two inner ratchet claws 27 step the upper ratchet plate 23 in the direction close to the evaporator tube 3. Each time the swing mounting plate 25 swings once, the upper ratchet plate 23 moves twice, and the upper ratchet claws 27 move the upper ratchet plate 23 to the evaporator tube 3. The plate 23 pushes the central axis 6 to move at the same time through the adapter 21, and the central axis 6 drives the spiral stirring blade 7 to move. When the central axis 6 moves to the end of one side, the lever on the central axis 6 touches the travel switch in the evaporator tube 3. At this time, the travel switch controls a pair of first electromagnets in the inner pawl 27 through the control system to energize, so that the inner pawl 27 is adsorbed to the edge of the swing mounting plate 25. After the inner pawl 27 passes the elastic locking cap 29, even if the first electromagnet is powered off, the inner pawl 27 will be blocked by the elastic locking cap 29, and the inner pawl 27 cannot contact the upper ratchet plate 23. The swing mounting plate 25 continues to swing and will not drive the central axis 6 to move.

[0032] All the inner pawls 27 and the outer pawls 28 are provided with first electromagnets inside, and the two pairs of first electromagnets are connected to the control system circuit. Four deep grooves are provided on the swing mounting plate 25, and an elastic locking cap 29 is provided in each deep groove. A second electromagnet is provided in each deep groove, and the two pairs of second electromagnets are also connected to the control system circuit. When the travel switch controls the first electromagnet in the inner pawl 27 to be energized, it also controls the second electromagnets in the two deep grooves close to the outer pawl 28 to be energized, and the second electromagnets suck the elastic locking cap 29 into the deep groove, and the two outer pawls 28 are free from the obstruction of the elastic locking cap 29. Under the action of the torsion force of the coil spring, the lower ratchet plate 24 approaches and is released. At this time, the swing mounting plate 25 continues to swing, and the outer ratchet 28 is used to push the lower ratchet plate 24 to move. The lower ratchet plate 24 drives the middle shaft 6 to move through the adapter 21, so that the spiral stirring blade 7 can reciprocate along the axial direction while rotating, thereby enhancing the stirring effect of the spiral stirring blade 7 on the beverage, until the middle shaft 6 moves to the end of the other side and is toggled to form a switch. The control system changes the working state of the inner ratchet 27 and the outer ratchet 28 by controlling the first electromagnet and the second electromagnet, so that the movement of the middle shaft 6 is changed.

[0033] The stirring mechanism also includes a driving bevel gear 15, a driven bevel gear 16, a connecting rod 17, a slider 18 and a rack 20. The driving bevel gear 15 is arranged on the motor shaft 13, and the driven bevel gear 16 is rotatably mounted on the rear seat 4. The driving bevel gear 15 is meshed with the driven bevel gear 16, and the slider 18 is slidably mounted on the rear seat 4. A rotating pin is eccentrically arranged on the upper end of the driven bevel gear 16, one end of the connecting rod 17 is rotatably connected to the rotating pin, and the other end of the connecting rod 17 is rotatably connected to the slider 18. An extension bracket 19 is connected to the slider 18, and a rack 20 is connected to the extension bracket 19. The rack 20 is meshed with a gear 26 for transmission. The main motor 14 rotates to drive the driving bevel gear 15 to rotate, and the driving bevel gear 15 drives the driven bevel gear 16 to rotate. The driven bevel gear 16 utilizes the eccentric rotating pin The connecting rod 17 drives the slider 18 to slide back and forth, and the slider 18 drives the rack 20 to move back and forth through the extended bracket 19. The reciprocating motion of the rack 20 drives the gear 26 to rotate back and forth, and the gear 26 causes the swing mounting plate 25 to swing repeatedly. Since the slider 18 has the characteristic of quick return motion driven by the driven bevel gear 16, the swing mounting plate 25 swings back and forth each time, and the swing speed is faster. Therefore, the movement of the inner pawl 27 or the outer pawl 28 on the central axis 6 is faster and slower. When the central axis 6 moves quickly, the spiral stirring blade 7 has an impact effect on the stirring of the beverage, so that the beverage frozen on the evaporator cylinder 3 is easier to be scraped off, avoiding freezing on the evaporator cylinder 3, enhancing the effect of melting snow and breaking ice, and at the same time enhancing the fluidity of the beverage in the beverage barrel 2 to prevent freezing.

[0034] The working principle of the present invention is as follows: the main motor 14 is energized to drive the spline shaft 12 to rotate, and the spline shaft 12 drives the central shaft 6 to rotate through the inner spline groove. Since the spline shaft 12 is slidably connected to the central shaft 6, the central shaft 6 can rotate while sliding along the axial direction. The central shaft 6 drives the end connecting block 8 to rotate, and the end connecting block 8 drives the spiral stirring blade 7 to rotate on the surface of the evaporator tube 3 to prevent the beverage from freezing after the evaporator tube 3 is frozen. When the swing mounting plate 25 swings, the two inner ratchets 27 step the upper ratchet plate 23 in the direction close to the evaporator tube 3. Each time the swing mounting plate 25 swings once, the upper ratchet plate 23 moves twice The upper ratchet plate 23 pushes the middle shaft 6 to move at the same time through the adapter 21, and the middle shaft 6 drives the spiral stirring blade 7 to move. When the middle shaft 6 moves to the end of one side, the lever on the middle shaft 6 touches the travel switch in the evaporator tube 3. At this time, the travel switch controls a pair of first electromagnets in the inner ratchet 27 through the control system to energize, so that the inner ratchet 27 is adsorbed to the edge of the swing mounting plate 25. After the inner ratchet 27 passes the elastic locking cap 29, even if the first electromagnet is powered off, the inner ratchet 27 will be blocked by the elastic locking cap 29, and the inner ratchet 27 cannot contact the upper ratchet plate 23. The swing mounting plate 25 continues to swing and will not drive the middle shaft 6 to move.

[0035] When the travel switch controls the first electromagnet in the inner pawl 27 to be energized, it also controls the second electromagnet in the two deep grooves near the outer pawl 28 to be energized. The second electromagnet sucks the elastic locking cap 29 into the deep groove, and the two outer pawls 28 break away from the obstruction of the elastic locking cap 29, and approach and release the lower ratchet plate 24 under the action of the torsion force of the coil spring. At this time, the swing mounting plate 25 continues to swing, and the outer pawl 28 is used to push the lower ratchet plate 24 to move. The lower ratchet plate 24 drives the middle axis 6 to move through the adapter 21, so that the spiral stirring blade 7 can reciprocate along the axial direction while rotating, thereby enhancing the stirring effect of the spiral stirring blade 7 on the beverage, until the middle axis 6 moves to the end of the other side and is toggled to form a switch. The control system changes the working state of the inner pawl 27 and the outer pawl 28 by controlling the first electromagnet and the second electromagnet, so that the movement of the middle axis 6 is changed.

[0036] The rotation of the main motor 14 drives the active bevel gear 15 to rotate, and the active bevel gear 15 drives the driven bevel gear 16 to rotate. The driven bevel gear 16 uses the eccentric rotating pin and the connecting rod 17 to drive the slider 18 to slide back and forth, and the slider 18 drives the rack 20 to move back and forth through the extension bracket 19. The reciprocating motion of the rack 20 drives the gear 26 to rotate back and forth, and the gear 26 causes the swing mounting plate 25 to swing repeatedly. Since the slider 18 has the characteristic of quick return motion under the drive of the driven bevel gear 16, the swing mounting plate 25 swings back and forth each time, and the swing speed is faster. Therefore, the movement of the inner ratchet 27 or the outer ratchet 28 on the central axis 6 is faster and slower. When the central axis 6 moves quickly, the spiral stirring blade 7 has an impact effect on the stirring of the beverage, so that the beverage frozen on the evaporator cylinder 3 is easier to be scraped off, avoiding freezing on the evaporator cylinder 3, enhancing the effect of melting snow and breaking ice, and at the same time enhancing the fluidity of the beverage in the beverage barrel 2 to prevent freezing.

[0037] When the snow melting machine stops working, the operator first drains the beverage in the beverage barrel 2, and then the control system starts the water pump to start working. The water pump pumps clean water into the high-pressure chamber through the water filling pipe 11. The small spring makes the rubber plug 9 seal in the water hole of the spiral stirring blade 7, and the spiral stirring blade 7 will not fall off when the spiral stirring blade 7 rotates. Due to the setting of the cone-shaped rubber plug 9, the beverage will not flow back into the spiral stirring blade 7 through the rubber plug 9; the pressure of the clean water in each water hole in the high-pressure chamber increases, and the water pressure overcomes the tension applied to the rubber plug 9 by the small spring. The clean water flushes the rubber plug 9 on the spiral stirring blade 7, and the clean water is sprayed onto the inner wall of the beverage barrel 2 for cleaning. The main motor 14 drives the spiral stirring blade 7 to rotate, and the clean water cleans the inner wall of the beverage barrel 2 in all directions. The clean water after cleaning is finally discharged from the water outlet of the beverage barrel 2. Through the setting of the hollow water filling ring 10 and the water opening hole of the spiral stirring blade 7, the snow melting machine is automatically cleaned, and the edges and corners that are difficult to clean are fully covered, eliminating the need for manual cleaning of the beverage barrel 2.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
