DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the description.

[0024] like Figures 1 to 4 As shown, the present invention discloses an ice cream machine, including a housing 10, a stirring mechanism 20, a motor, a temperature sensor 30 and a control device, wherein the housing 10 has a stirring chamber 121 for stirring ice cream; the stirring mechanism 20 is rotatably arranged in the stirring chamber 121; the motor is drivingly connected to the stirring mechanism 20; the temperature sensor 30 is arranged in the stirring chamber 121, and the temperature sensor 30 is used to detect the temperature of the ice cream; the control device is electrically connected to the temperature sensor 30 and the motor respectively, and the control device is used to control the rotation speed of the motor according to the temperature of the ice cream. The ice cream machine of the present invention can detect the temperature of the ice cream in the stirring chamber 121 through the temperature sensor 30 by arranging the temperature sensor 30 in the stirring chamber 121, and send the temperature information to the control device, and the control device controls the rotation speed of the motor according to the temperature of the ice cream, thereby adjusting the stirring speed of the stirring mechanism, reducing the ice cream from adhering to the stirring rod, and improving the stirring effect.

[0025] In the above embodiment, the temperature sensor 30 is disposed on the stirring mechanism 20. The ice cream machine of the present invention disposes the temperature sensor 30 on the stirring mechanism 20. Since the stirring mechanism 20 is in direct and constant contact with the ice cream during the stirring process, the detected temperature is more accurate.

[0026] In the above embodiment, the ice cream machine further includes a top cover 40, the housing 10 further includes a material inlet 122 communicating with the stirring chamber 121, the top cover 40 can open or close the material inlet 122, and the stirring mechanism 20 is mounted on the top cover 40. The ice cream machine of the present invention installs the stirring mechanism 20 on the top cover 40, and the stirring mechanism 20 is placed into or taken out of the stirring chamber 121 when the cover is opened or closed, thereby making the operation steps more convenient.

[0027] In the above embodiment, the stirring mechanism 20 includes a stirring rod 21 and a stirring paddle 22, and the temperature sensor 30 is arranged on the stirring rod 21; the stirring paddle 22 is connected to the stirring rod 21. The ice cream machine of the present invention arranges the temperature sensor 30 on the stirring rod 21, and since the stirring rod 21 is in direct and constant contact with the ice cream during the stirring process, the detected temperature is more accurate.

[0028] In the above embodiment, there are multiple stirring paddles 22, and the multiple stirring paddles 22 are arranged at intervals along the outer circumference of the stirring rod 21, which can stir the ice cream more evenly and improve the heat exchange efficiency during the stirring process.

[0029] In the above embodiment, a hollow structure 23 is provided on the stirring paddle 22. The ice cream machine of the present invention is provided with the hollow structure 23, so that the stirring paddle 22 stirs the ice cream more fully during stirring, thereby improving the heat exchange efficiency.

[0030] In the above embodiment, the side of the hollow structure 23 close to the stirring rod 21 forms an arc-shaped protrusion 231, and the arc-shaped protrusion 231 protrudes away from the stirring rod 21. The ice cream machine of the present invention can push the ice cream with a higher temperature near the stirring rod 21 toward the side wall of the stirring chamber 121 by providing the arc-shaped protrusion 231, so that it is mixed with the low-temperature ice cream near the stirring chamber 121, thereby improving the heat exchange efficiency and the stirring effect.

[0031] In the above embodiment, a sawtooth structure 232 is formed on one side of the outer peripheral edge of the hollow structure 23 near the stirring paddle 22. The ice cream machine of the present invention can push the low-temperature ice cream near the side wall of the stirring chamber 121 toward the stirring rod 21 by providing the sawtooth structure 232, so that it is mixed with the high-temperature ice cream near the stirring rod 21, thereby improving the heat exchange efficiency and the stirring effect.

[0032] In the above embodiment, the stirring paddle 22 is a plate-like structure, the first end of the stirring paddle 22 is fixed on the stirring rod 21, and the second end of the stirring paddle 22 is a free end. The thickness of the free end gradually decreases in the direction away from the stirring rod 21, which is convenient for scraping the ice cream on the side wall of the stirring chamber 121, thereby improving the stirring effect of the ice cream.

[0033] In the above embodiment, the stirring paddle 22 is wavy in shape as a whole. The ice cream machine of the present invention can guide the ice cream during the stirring process by setting the stirring paddle 22 to be wavy in shape as a whole, and guide the ice cream into the hollow structure 23, so that the ice cream can flow and mix more fully, thereby improving the heat exchange efficiency and the stirring effect.

[0034] In the above embodiment, the housing 10 includes an outer shell 11 and an inner liner 12, the outer shell 11 has a receiving cavity; the inner liner 12 has a stirring cavity 121, the inner liner 12 is arranged in the receiving cavity, and a cold storage cavity 13 for accommodating cold storage liquid is formed between the inner liner 12 and the outer shell 11. The ice cream machine of the present invention forms a cold storage cavity 13 between the inner liner 12 and the outer shell 11 by arranging the outer shell 11 and the inner liner 12, and the cold storage cavity 13 is filled with cold storage liquid with a freezing point of -12°C.

[0035] In the above embodiment, a mounting cavity 41 is provided in the top cover 40, and the motor and the control device are provided in the mounting cavity 41. The ice cream machine also includes a timer and a voice prompt device, which are provided in the mounting cavity 41, and are electrically connected to the control device. The ice cream machine of the present invention can realize an automatic shut-off working mode by setting a timer. When in use, the working time is set by the timer, and the ice cream machine is automatically shut down after the timing ends, thereby avoiding manual shutdown. At the same time, the user can be reminded by voice when the timing ends.

[0036] Before making ice cream, it is necessary to put the shell 10 of the ice cream machine into the freezer of the refrigerator to completely freeze the cold storage liquid. When making ice cream, take out the frozen shell 10, mix the ice cream ingredients and pour them into the inner tank 12, and then turn on the ice cream machine. The ice cream machine starts to stir. As the stirring proceeds, the ice cream begins to freeze and cool down. Generally, when the temperature drops to -2.5°C, the ice cream will slowly stick to the stirring rod 21 and the stirring paddle 22. At this time, the control device receives the signal from the temperature sensor 30, controls the motor speed, speeds up the stirring, prevents the ice cream from sticking to the stirring rod, and improves the expansion rate and production efficiency of the ice cream. When the temperature of the ice cream drops to -4°C, the ice cream is formed. At this time, the voice reminds the user that the ice cream is made and turns off the ice cream machine.

[0037] In the above embodiments, the ice cream machine is usually turned on and off by a button. Of course, an electronic touch control method or a voice control method can also be used. The electronic touch control method can make the ice cream machine more technological and intelligent as a whole, while the voice control method can facilitate user operation.

[0038] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. 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.
