Description

Technical Field

[0001] This utility model specifically relates to a slush machine with a stirring paddle that can rotate in both directions. Background Technology

[0002] Existing slush machines have a mixing paddle that fits over the stainless steel cylinder of the evaporator. The paddle head has a certain height for pushing the slush out of the outlet. This creates a large "difficult-to-cool-down area" between the front of the evaporator and the outlet of the beverage container. When the user adds the minimum amount of liquid food to make slush, as the liquid food gradually thickens, due to the insufficient amount of raw materials added, almost all of the semi-formed slush will accumulate in the aforementioned "difficult-to-cool-down area" and adhere to the inner wall of the front of the beverage container under the unidirectional push of the mixing paddle. This part of the liquid food is relatively thin and far from achieving the desired slush state.

[0003] At this point, there is almost no liquid left on the evaporator for further cooling. Due to the one-way stirring and pushing of the paddle and the lack of subsequent liquid replenishment, the semi-formed slush accumulated at the front of the beverage container is difficult to flow back to the evaporator area for continued cooling. The semi-formed slush can only slowly melt over time and then slowly flow back to contact the evaporator (due to the one-way rotation of the paddle, even if some of the semi-formed slush melts, it is difficult for it to flow back). As a result, the minimum amount of liquid food cannot be made into formed slush in the user's expected short time, but will take several times longer than expected, and most of the time only semi-formed slush can be obtained. Utility Model Content

[0004] The purpose of this invention is to provide a slush machine with a bidirectional rotating stirring paddle that can make liquid food fully contact the surface of the evaporator.

[0005] The above objectives are achieved in this way.

[0006] A slush machine with a bidirectional rotating stirring paddle includes a base, an evaporator fixedly mounted on the base, a beverage tank movably mounted on the base, a stirring paddle arranged around the evaporator, and a drive mechanism for driving the stirring paddle to rotate. The inner end of the beverage tank has an opening, and when the beverage tank is connected to the base, the beverage tank fits around the evaporator through the opening. The stirring paddle includes a drive shaft coaxially arranged with the evaporator and stirring blades installed outside the evaporator. The stirring paddle is driven by the drive mechanism, which is a motor capable of bidirectional rotation. The forward rotation of the motor controls the forward rotation of the stirring paddle, and the reverse rotation of the motor controls the reverse rotation of the stirring paddle. The stirring paddle has a spiral A surface and a spiral B surface. When the motor rotates forward, the spiral A surface pushes the raw material deep in the beverage tank to the top of the stirring paddle and keeps the raw material in continuous contact with the evaporator. When the motor rotates in reverse, the spiral B surface pushes the raw material on the top surface of the stirring paddle deeper into the beverage tank and keeps the raw material in continuous contact with the evaporator.

[0007] The objective of this utility model can also be optimized by the following technical measures.

[0008] Preferably, the motor is a DC brushed motor, a brushless motor, a dual-steering AC motor, or a stepper motor.

[0009] Preferably, the spiral A surface and the spiral B surface are arranged symmetrically.

[0010] By adopting the above technical solution, this utility model, through the setting of a motor that can rotate in both directions, when the semi-formed slush reaches the "difficult-to-cool area" between the front end of the evaporator and the outlet of the beverage tank, the motor is started to rotate in reverse, driving the stirring paddle to rotate in reverse. The spiral B surface on the stirring paddle will drive the semi-formed slush backward and prevent it from accumulating at the front end of the beverage tank, allowing the semi-formed slush to have sufficient time to contact the evaporator. Then the stirring motor rotates in the forward direction again, and the spiral A surface on the stirring paddle will push the semi-formed slush forward and prevent it from accumulating at the rear end of the beverage tank. This process is repeated, ensuring that the food liquid is in contact with the evaporator throughout the process without any gaps. Because the food liquid has sufficient time to absorb the cold energy of the evaporator and cool down, it is transformed into beautifully formed slush in the shortest possible time through the stirring of the stirring paddle.

The stirring paddle 3 is driven by a drive mechanism 5, which is a motor capable of rotating in both directions.

[0018] The forward rotation of the motor controls the forward rotation of the agitator 3, and the reverse rotation of the motor controls the reverse rotation of the agitator 3.

[0019] Combination Figure 2 and Figure 4 The stirring paddle 3 has a spiral A surface 31 and a spiral B surface 32, which are symmetrically arranged. When the motor rotates in the forward direction, the spiral A surface 31 pushes the raw material deep in the beverage cylinder 2 to the top of the stirring paddle 3 and keeps the raw material in continuous contact with the evaporator 4. When the motor rotates in the reverse direction, the spiral B surface 32 pushes the raw material on the top surface of the stirring paddle 3 deeper into the beverage cylinder 2 and keeps the raw material in continuous contact with the evaporator 4.
