Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a vertical frozen food manufacturing equipment. Background Technology

[0002] Currently, a typical vertical snow melting machine includes an upward-opening material tank, a refrigeration evaporator located inside the tank, and a rotating impeller positioned between the inner wall of the tank and the outer wall of the evaporator. The material tank has a discharge port at its lower part, and a cover is installed at the opening. A motor, with its output shaft pointing downwards and connected to the upper end of the impeller, is mounted on the cover. When adding raw materials or cleaning the tank, the cover and motor must be removed together, which is very laborious. More importantly, the space required for the motor and its installation inevitably increases the overall height of the vertical snow melting machine, making it too tall and unsuitable for installation and use in space-constrained environments.

[0003] Moreover, the cylindrical refrigeration evaporator is concentrically installed in the middle of the inner cavity of the material barrel, forming an annular gap between the inner wall of the material barrel and the outer wall of the evaporator. The stirring impeller is located in this annular gap, which makes the volume of frozen food that can be contained in the material barrel relatively small. In order to ensure the volume that can be used to make frozen food, the height of the material barrel is forced to be further increased, which in turn leads to a further increase in the overall height of the machine. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a vertical frozen food manufacturing equipment that reduces the height while ensuring the volume that can be used to make frozen food.

When adding raw materials or cleaning the material tank, you only need to open the opening of the cavity by opening the cover, which is easy to operate. The refrigeration pipes are coiled around the outer wall of the material tank, which helps to increase the volume of frozen food that can be held in the material tank. The motor is located at the bottom of the material tank, which avoids increasing the overall height of the vertical frozen food manufacturing equipment, which is beneficial for use in space-constrained environments.

[0008] In some embodiments of this utility model, the discharge port is connected to a discharge pipe that extends away from the motor.

[0009] In some embodiments of this utility model, the discharge pipe is a bent pipe extending downwards away from the motor, with both the upper and lower ports of the bent pipe arranged vertically, and the lower end of the housing having a loading platform facing the lower port of the bent pipe.

[0010] In some embodiments of this utility model, the housing has a convex shell portion protruding from the middle position along its height direction, located above the loading platform.

[0012] In some embodiments of this utility model, the housing includes a lower shell and an upper shell. A first arc-shaped plate and a horizontal overhang plate intersecting the lower end of the first arc-shaped plate are protruding from one side of the upper part of the lower shell. The lower end of the bent pipe is fixedly inserted through the horizontal overhang plate. A second arc-shaped plate is protruding from one side of the lower part of the upper shell. A portion of the outer peripheral wall of the second arc-shaped plate can be tightly inserted into the inner peripheral wall of the first arc-shaped plate, so that the upper edge of the lower shell and the lower edge of the upper shell are spliced ​​together as one piece.

[0013] In some embodiments of this utility model, the upper edge of the second arc-shaped plate is connected to the upper shell by a downwardly inclined plate portion.

[0014] In some embodiments of this utility model, the stirring impeller has a rotating shaft portion, the lower end of the rotating shaft portion is provided with a drive groove that cooperates with the output shaft of the motor, the lower end surface of the cover is provided with a shaft hole portion for the upper end of the rotating shaft portion to rotate, and the cover is made of a light-transmitting material.

[0028] See Figures 1 to 3This utility model discloses a vertical frozen food manufacturing equipment, comprising: a shell 100 extending vertically; a material tank 200 disposed at the top of the shell 100; the material tank 200 having an upward-opening cavity 210; a cover 220 detachably mounted on the top of the shell 100 for opening and closing the cavity 210; a stirring impeller 300 rotatably disposed inside the material tank 200; a motor 400 disposed at the bottom of the material tank 200; the output shaft of the motor 400 vertically extending upward through the bottom wall of the material tank 200 to drive the stirring impeller 300 to rotate; a discharge port 230 located on one side of the motor 400 on the bottom wall of the material tank 200; a refrigeration pipe 800 coiled around the outer peripheral wall of the material tank 200 along its height direction; and the blades of the stirring impeller 300 being able to abut against the inner peripheral wall of the material tank 200.

[0029] The discharge port 230 of the above-mentioned vertical frozen food manufacturing equipment is located on the bottom wall of the material tank 200. The motor 400 is located on the outer bottom of the material tank 200 and on one side of the discharge port 230. When the motor 400 drives the stirring impeller 300 to rotate, it can drive the material to be discharged outward through the discharge port 230 and the discharge pipe 500. When adding raw materials or cleaning the material tank 200, it is only necessary to open the opening of the cavity 210 by opening the cover 220, which is labor-saving. The refrigeration pipe 800 is coiled around the outer peripheral wall of the material tank 200, which helps to increase the volume of frozen food that can be contained in the material tank 200. The motor 400 is located below the material tank 200, which avoids increasing the overall height of the vertical frozen food manufacturing equipment, which is beneficial for use in environments with limited space.

[0030] In some embodiments of this utility model, the discharge port 230 is connected to a discharge pipe 500 extending away from the motor 400. When the motor 400 is located below the material tank 200, the discharge port 230 is located on one side of the motor 400. The frozen food is conveyed to a preset position by the discharge pipe 500 extending away from the motor 400, avoiding interference with the motor 400 and not affecting the normal discharge of the vertical frozen food manufacturing equipment.

[0031] See Figure 2 and Figure 3 In some embodiments of this utility model, the discharge pipe 500 is a bent pipe extending downwards away from the motor 400. Both the upper and lower ends of the bent pipe are arranged vertically. The lower end of the housing 100 is provided with a loading platform 600 facing the lower end of the bent pipe. It is understood that the loading platform 600 is used to place cups or other food containers for holding frozen food. The bent pipe conveys the frozen food discharged from the outlet 230 to the top of the loading platform 600. The bent design of the discharge pipe 500 helps to minimize the space occupied below the material container 200, providing more space for the motor 400.

[0032] See Figures 1 to 3 In some embodiments of this utility model, the housing 100 has a convex shell portion 130 protruding from the middle position along its height direction, located above the loading platform 600. The convex shell portion 130 and the loading platform 600 define a space for placing a food container. The lower end of the bent tube is fixedly inserted through the lower end plate of the convex shell portion 130. There is a height gap between the upper end of the bent tube and the outer bottom surface of the material barrel 200. A switch plate 710 is movably disposed within the height gap. The switch plate 710 is provided with a communication port 711 that can connect the discharge port 230 and the upper end of the bent tube. It should be noted that during the frozen food preparation process, the switch plate 710 closes the discharge port 230. The raw materials in the cooling tank 200 of the refrigeration evaporator are then stirred by the impeller 300 to form frozen foods such as smoothies, ice cream, and sorbets. After the frozen food is processed, the user places the cup on the loading platform 600, and the switch plate 710 moves until the connecting port 711 aligns with the discharge port 230. The frozen food is then discharged downwards into the cup along the discharge pipe 500. The convex shell 130 is designed to shield the top of the cup opening, preventing dust from contaminating the frozen food.

[0033] See Figure 2 and Figure 3 In some embodiments of this utility model, in order to prevent raw materials or frozen food from leaking out between the discharge port 230 and the switch plate 710, a first sealing ring 720 located on the outer periphery of the discharge port 230 is fixedly provided on the outer bottom wall of the material barrel 200. The switch plate 710 abuts against the lower end face of the first sealing ring 720 and the upper end face of the bent pipe. In order to electrically control the opening and closing of the discharge port 230, the switch plate 710 is connected to a rotary driver 730 that drives it to rotate around the vertical axis.

[0034] See Figure 1 and Figure 2In some embodiments of this utility model, the housing 100 includes a lower housing 110 and an upper housing 120. A first arc-shaped plate 111 and a horizontal overhanging plate 112 intersecting the lower end of the first arc-shaped plate 111 are protruding from one side of the upper portion of the lower housing 110. The lower end of the bent pipe is fixedly inserted through the horizontal overhanging plate 112. A second arc-shaped plate 121 is protruding from one side of the lower portion of the upper housing 120. A portion of the outer peripheral wall of the second arc-shaped plate 121 can be tightly fitted into the inner peripheral wall of the first arc-shaped plate 111, so that the upper edge of the lower housing 110 and the lower edge of the upper housing 120 are integrally joined. It is understood that the housing 100 is composed of two independent parts, the lower housing 110 and the upper housing 120, to facilitate the fixed installation of the lower end of the bent pipe and the assembly of components such as the compressor, motor 400, material tank 200, refrigeration evaporator, and condenser. The horizontal cantilever plate 112 is provided with a through hole for the lower end of the bent pipe to pass through. The lower end of the bent pipe can be fixed to the through hole by ultrasonic welding. The lower shell 110 and the upper shell 120 are positioned by the cooperation of the second arc plate 121 and the first arc plate 111, and then fastened with a small number of screws.

[0035] See Figure 1 and Figure 2 In some embodiments of this utility model, in order to reduce the accumulation of dust, the upper edge of the second arc-shaped plate 121 is connected to the upper shell 120 by a downwardly inclined plate portion 122.

[0036] See Figure 2 In some embodiments of this utility model, the stirring impeller 300 has a rotating shaft portion 310. The lower end of the rotating shaft portion 310 is provided with a drive groove that cooperates with the output shaft of the motor 400. The lower end surface of the cover 220 is provided with a shaft hole portion 221 for the upper end of the rotating shaft portion 310 to rotate. The cover 220 is made of a light-transmitting material. It should be noted that the cross-section of the drive groove is non-circular, and the cross-section of the part of the rotating shaft portion 310 that cooperates with the drive groove is also non-circular, thereby transmitting torque. The user can observe the situation inside the material container 200 through the cover 220, which is beneficial for manual judgment of the processing stage of frozen food. The shaft hole portion 221 on the cover 220 plays a role in rotational guidance and support for the rotation of the stirring impeller 300. When the cover 220 opens the opening of the cavity 210, only the cover 220 needs to be removed separately. The stirring impeller 300 can also be removed from the material container 200 for separate cleaning.

[0037] See Figure 2In some embodiments of this utility model, in order to reduce the loss of cold energy, reduce the power consumption of the vertical frozen food manufacturing equipment, and accelerate the manufacturing speed of frozen food, the material tank 200 includes an inner cylindrical tank 201 and an outer cylindrical tank 202 concentrically sleeved on the outside of the inner cylindrical tank 201. The refrigeration pipe 800 is wound around the outer peripheral wall of the inner cylindrical tank 201. A heat insulation layer 900 is filled between the inner peripheral wall of the outer cylindrical tank 202 and the outer peripheral wall of the inner cylindrical tank 201. The heat insulation layer 900 is generally made of foam material, rubber and plastic heat insulation material, etc.

[0038] See Figure 2 and Figure 3 In some embodiments of this utility model, in order to reduce the difficulty of production and assembly of the above-mentioned material barrel 200 and refrigeration pipe 800, the upper end of the inner cylindrical barrel 201 and the upper end of the outer cylindrical barrel 202 are connected by a circular ring plate. The inner cylindrical barrel 201, the outer cylindrical barrel 202 and the circular ring plate define a heat-insulating cavity with an opening facing downward. The heat-insulating layer 900 is located inside the heat-insulating cavity. The material barrel 200 also includes a bottom plate 203 that closes the opening of the heat-insulating cavity. The discharge port 230 is opened on the bottom plate 203.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
