[0019] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the description.

[0020] like Figures 1 to 3As shown, the present invention discloses an ice cream machine, including a housing 10 and a stirring mechanism 20, wherein the housing 10 has a stirring chamber 11 for stirring ice cream; the stirring mechanism 20 is rotatably arranged in the stirring chamber 11, and the stirring mechanism 20 includes a turbine 21, which is rotatable and used to push the ice cream toward the inner wall of the stirring chamber 11. The ice cream machine of the present invention can be configured with the turbine 21 in the stirring mechanism 20, so that the stirring mechanism 20 can stir the ice cream while the turbine 21 pushes the ice cream toward the inner wall of the stirring chamber 11, so that the ice cream is fully stirred, and the heat exchange efficiency is improved, while the ice cream is prevented from adhering to the stirring mechanism 20, and the forming speed of the ice cream is improved.

[0021] In the above embodiment, the turbine 21 can rotate independently. The turbine 21 of the ice cream machine of the present invention can rotate independently and can be flexibly adjusted according to the state of the ice cream. For example, when making ice cream, the stirring mechanism 20 rotates quickly as a whole to accelerate the heat exchange between the ice cream liquid and the wall surface. After the ice cream becomes thick, the stirring mechanism 20 is changed to a low speed as a whole. Because the temperature difference decreases, the heat exchange efficiency becomes low, and it is necessary to extend the contact time between the ice cream and the wall surface to improve the heat exchange. When the ice cream is further cooled and frozen, only the turbine 21 can rotate at a high speed to prevent the ice cream from sticking to the stirring rod.

[0022] In the above embodiment, the stirring mechanism 20 includes a stirring rod 22 and a stirring paddle 23. The stirring rod 22 rotates in the stirring chamber 11 to stir the ice cream, and the turbine 21 is rotatably disposed on the stirring rod 22. The ice cream machine of the present invention arranges the turbine 21 on the stirring rod 22, so that the ice cream can be stirred by the turbine 21 while the stirring rod 22 stirs the ice cream, so that the ice cream can be stirred more fully, and the heat exchange efficiency of the ice cream in the early stage can be improved. In the later stage of ice cream making, when it is about to freeze and solidify, the rotation of the turbine 21 can prevent the ice cream from sticking to the stirring rod, thereby improving the stirring effect.

[0023] In the above embodiment, the stirring rod 22 is a hollow structure; the stirring mechanism 20 further includes a transmission assembly, which is arranged inside the stirring rod 22 and is drivingly connected to the turbine 21. The ice cream machine of the present invention can arrange the transmission assembly inside the stirring rod 22 by arranging the stirring rod 22 as a hollow structure, thereby saving space in the stirring chamber 11 and making the overall structure simpler.

[0024] In the above embodiment, the transmission assembly includes a driving rod 24, a first bevel gear 25 and a second bevel gear 26. The driving rod 24 is rotatable relative to the stirring rod 22. The first bevel gear 25 is arranged on the driving rod 24, and the driving rod 24 drives the first bevel gear 25 to rotate. The second bevel gear 26 is drivingly connected to the rotating shaft of the turbine 21, and the first bevel gear 25 is meshed with the second bevel gear 26. The ice cream machine of the present invention can make the driving rod 24 rotate relative to the stirring rod 22 by arranging the driving rod 24, the first bevel gear 25 and the second bevel gear 26. When the driving rod 24 rotates relative to the stirring rod 22, the driving rod 24 drives the first bevel gear 25 to rotate, the first bevel gear 25 drives the second bevel gear 26 to rotate, and the second bevel gear 26 drives the turbine 21 to rotate, thereby realizing the separate rotation of the stirring rod 22 and the turbine 21. This arrangement method enables the stirring rod 22 to have a double stirring effect without occupying additional space in the stirring chamber 11, which can not only improve the stirring effect of the ice cream, but also prevent the ice cream from adhering to the stirring rod 22, thereby improving the heat exchange efficiency of the ice cream.

[0025] In the above embodiment, the ice cream machine further comprises a driving device 30, which is drivingly connected to the stirring mechanism 20. The ice cream machine of the present invention drives the stirring mechanism 20 to rotate by the driving device 30 to stir the ice cream, thereby improving the stirring efficiency.

[0026] In the above embodiment, the driving device 30 includes a first motor 31 and a second motor 32, wherein the first motor 31 is drivingly connected to the stirring rod 22; the second motor 32 is drivingly connected to the driving rod 24, and the second motor 32 is used to adjust the rotation speed of the driving rod 24 relative to the stirring rod 22. The ice cream machine of the present invention can drive the corresponding stirring rod 22 and driving rod 24 respectively through the first motor 31 and the second motor 32, thereby realizing the independent rotation of the stirring rod 22 and the turbine 21. When in use, the speed of the driving rod 24 relative to the stirring rod 22 can be adjusted by changing the rotation direction and speed of the second motor 32, thereby controlling the rotation speed of the turbine 21.

[0027] In the above embodiment, the stirring mechanism 20 includes a stirring paddle 23, which is arranged on the stirring rod 22, and a hollow structure 231 is arranged on the stirring paddle 23, and the turbine 21 is located at the position of the hollow structure 231. The ice cream machine of the present invention can improve the stirring effect of ice cream by arranging the stirring paddle 23, and arranging the turbine 21 at the hollow structure 231, so that the turbine 21 can act as a part of the stirring paddle 23 when it is not rotating, and when it rotates, the ice cream near the stirring paddle 23 can be pushed to the inner wall of the stirring chamber 11, thereby preventing the ice cream from adhering to the stirring paddle 23.

[0028] In the above embodiment, the rotation axis of the turbine 21 intersects with the rotation axis of the stirring rod 22. The ice cream machine of the present invention makes the rotation axis of the turbine 21 intersect with the rotation axis of the stirring rod 22 so that the two can form a certain angle, so that the stirring area is larger, which helps to improve the stirring effect.

[0029] In the above embodiment, the ice cream machine further includes a top cover 40, a driving device 30 is installed in the top cover 40, a stirring mechanism 20 is installed on the top cover 40, and the driving device 30 is drivingly connected to the stirring mechanism 20. The ice cream machine of the present invention can be provided with the top cover 40, and the stirring mechanism 20 can be removed together with the top cover 40, so as to facilitate the discharge of materials and the removal of finished products.

[0030] In the above embodiment, an inner liner is arranged in the shell, a stirring chamber is provided in the inner liner, and a cold storage chamber for containing cold storage liquid is formed between the inner liner and the shell.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
