Description

Technical Field

[0001] The utility model relates to the technical field of cold drink machines, in particular to a cold drink machine with infrared sensing. Background Art

[0002] Cold drink machines continuously stir the ice cream or slush ingredients, achieving efficient heat exchange with the freezing cylinder, ensuring that the ice cream or slush reaches the required low temperature quickly and stably during the production process. However, cold drink machines are unable to adjust the stirring speed and frequency based on the current operating status, causing the cold drink machine to often operate continuously.

[0003] Prolonged stirring causes the water in the ice cream or smoothie ingredients to gradually crystallize into fine ice slag, which not only affects the delicate taste of the ice cream or smoothie but can also make the overall texture rough, reducing the consumer's eating experience. Furthermore, since the cold drink machine requires constant stirring during the production process, prolonged operation of the motor can accelerate the aging and wear of the motor's internal components, thereby shortening the motor's lifespan. Utility Model Content

[0004] In response to the above-mentioned defects, the utility model proposes a cold drink machine with infrared sensing. The coordinated work of the sensing device, the driving part, and the refrigeration and stirring assembly ensures that the system will start the corresponding working mode only when there is a real need to discharge the material. This solves the problem in traditional cold drink machines that the stirring system is often in a continuous running state even when there is no need to discharge the material, causing the taste of ice cream or smoothie to deteriorate due to long-term stirring.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0026] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installation," "splicing," and "connection" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] The following combination Figures 1 to 4 , describing a cold drink machine with infrared sensing in an embodiment of the present utility model.

[0028] A cold drink machine with infrared sensing includes a discharging device 2, a sensing device 3, a refrigeration stirring component 4 and a driving member installed on a body 1. The discharging device 2 is provided with a handle 21, and the sensing device 3 is arranged opposite to the handle 21. The sensing device 3 is electrically connected to the driving member. The sensing device 3 is used to identify the usage status of the handle 21 to adjust the operating status of the driving member. The driving member is used to adjust the stirring speed of the refrigeration stirring component 4.

[0029] The infrared sensor-enabled cold drink dispenser of this embodiment operates as follows: When a worker naturally grips or gently swings handle 21 downward, sensor 3 detects the motion and identifies it as a request to dispense. Sensor 3 then adjusts the operating state of the drive element, increasing the stirring speed of refrigeration and stirring assembly 4 to ensure that the ice cream or sorbet is dispensed evenly and smoothly, preserving its original smooth texture and ensuring that every bite of ice cream or sorbet achieves optimal flavor and texture.

[0030] When the staff releases the handle 21, the sensing component recognizes that the handle 21 is in the initial state, adjusts the operating state of the drive component, and reduces the stirring speed of the refrigeration stirring component 4 to avoid texture changes or ice crystal formation of the ice cream or smoothie due to excessive stirring and excessive cooling, further ensuring the taste and flavor of the ice cream or smoothie.

[0031] In the present invention, the cooperative work of the sensing device 3 and the driving part and the refrigeration stirring assembly 4 ensures that the system will start the corresponding working mode only when discharging is really needed, which solves the problem in traditional cold drink machines that the stirring system is often in a continuous running state even when there is no demand for discharging, causing the taste of ice cream or smoothie to deteriorate due to long-term stirring.

[0032] The sensing component includes an infrared generator 31 and an infrared receiver 32 . The infrared receivers 32 are electrically connected to the driving components respectively. The infrared generator 31 is used to emit red light to the handle 21 , and the infrared receiver 32 is used to receive the red light reflected by the handle 21 .

[0033] The infrared generator 31 precisely emits red light. If the operator holds the handle 21 or swings it downward, the red light cannot reach the handle 21 and is reflected, preventing the infrared receiver 32 from receiving the red light reflected by the handle 21. The sensor device 3 then adjusts the operating state of the driver based on this signal, thereby increasing the stirring speed of the refrigeration stirring assembly 4.

[0034] If the operator releases the handle 21 and the handle 21 is in its initial state, the infrared generator 31 can emit infrared light to the handle 21, which reflects the light, allowing the infrared receiver 32 to receive the reflected red light. At this time, the infrared receiver 32 can adjust the operating state of the driving member based on the signal, thereby reducing the stirring speed of the refrigeration stirring assembly 4 and reducing the refrigeration power.

[0035] Therefore, through the cooperation between the infrared generator 31 and the infrared receiver 32, it is possible to accurately determine whether the cold drink machine needs to discharge the material, and adjust the operating status of the drive member and the refrigeration and stirring assembly 4 accordingly. This instant response mechanism ensures that the ice cream or smoothie is discharged at the optimal time, preserving its original flavor and taste while avoiding unnecessary energy waste.

[0036] The infrared generator 31 and the infrared receiver 32 are respectively located on both sides of the handle 21 , and the infrared generator 31 , the infrared receiver 32 and the handle 21 form a triangle structure.

[0037] In this solution, the positions of the infrared generator 31 and the infrared receiver 32 are defined, which can ensure that when the cold drink machine is not in operation, even if the cold drink machine is vibrated by external factors, the infrared generator 31 can emit infrared light toward the outer handle 21, and the infrared receiver 32 can receive the infrared light reflected by the handle 21, thereby ensuring the stability and reliability of the cold drink machine.

[0038] Moreover, when the staff holds the handle 21 or the handle 21 tilts downward to discharge materials, the triangular structure design can ensure that the infrared receiver 32 cannot receive the red light from the infrared generator 31, thereby improving the operating accuracy of the cold drink machine.

[0039] The refrigeration stirring assembly 4 includes a propeller 41 and a freezing cylinder 42. The propeller 41 is rotatably installed in the freezing cylinder 42. The length direction of the propeller 41 is consistent with the length direction of the freezing cylinder 42. The output end of the driving member is fixedly connected to the propeller 41.

[0040] The freezing cylinder 42 has excellent freezing performance, which can provide a solid foundation for the rapid solidification of ice cream or smoothie. When the propeller 41 stirs the cold drink, the contact between its blades and the inner wall of the freezing cylinder 42 causes heat conduction between the ice cream or smoothie and the freezing cylinder 42, thereby achieving a cooling effect.

[0041] When the ice cream or smoothie is in the discharging state, the driving part accelerates the rotation speed of the propeller 41, which not only ensures that the ice cream or smoothie can be stably transported outward by the cold drink machine, but also allows the blades to frequently contact the inner wall of the freezing cylinder 42, greatly increasing the heat exchange area between the ice cream or smoothie and the freezing cylinder 42, thereby significantly accelerating the heat release inside the ice cream or smoothie, improving the overall refrigeration efficiency, and allowing the ice cream or smoothie to maintain an ideal taste and flavor when discharging.

[0042] The discharging device 2 also includes a discharging tray 22, which is used to seal the freezing cylinder 42. The discharging tray 22 is provided with a first discharging port, which is communicated with the interior of the freezing cylinder 42. A transmission assembly 23 and a seal 24 are provided at the bottom of the handle 21. The transmission assembly 23 connects the handle 21 and the seal 24, and the seal 24 is used to open or close the first discharging port.

[0043] When the handle 21 is swung downward, it in turn drives the transmission assembly 23 and the seal 24, causing the seal 24 to open the first discharge port. The sensing device 3 senses the current state of the handle 21 and promptly adjusts the speed of the driving member, allowing the propeller 41 to quickly stir the ice cream or sorbet, ensuring that the ice cream or sorbet maintains a good taste and flavor while ensuring stable discharge.

[0044] When the staff releases the handle 21, the sensing device 3 can quickly recognize that the handle 21 has returned to its original position, and adjust the rotation speed of the driving part accordingly, so that the propeller 41 slowly and intermittently stirs the ice cream or smoothie, reducing the situation where the taste of the ice cream or smoothie deteriorates due to long-term stirring.

[0045] It is worth noting that the seal 24 is preferably made of food-grade rubber material. The seal 24 fits tightly against the first discharge port, ensuring that the ice cream or smoothie ingredients are completely sealed in the freezing cylinder 42 when not being discharged, thereby preventing the ice cream or smoothie from leaking or spoiling due to a loose seal.

[0046] The transmission assembly 23 includes a first transmission member 25 and a second transmission member 26. The first hinge point of the handle 21 is rotatably mounted on the top of the discharge tray 22 at the first discharge port. The second hinge point of the handle 21 is rotatably connected to the top of the first transmission member 25. The bottom of the first transmission member 25 is connected to the top of the rear side of the second transmission member 26. The bottom of the second transmission member 26 is fixedly connected to the sealing member 24.

[0047] In an initial state, the direction of the line connecting the first hinge point and the second hinge point is horizontal.

[0048] In this solution, the direction of the connection line between the first hinge point and the second hinge point of the handle 21 is defined, which can effectively ensure that when the handle 21 is swung outward, the handle 21 can drive the first transmission member 25 and the second transmission member 26 to move in turn, so that the bottom of the second transmission member 26 drives the seal 24 to move, so that the seal 24 can open the first discharge port, so that the ice cream or smoothie is squeezed out of the freezing cylinder 42 into the first discharge port, completing the discharge of the ice cream or smoothie.

[0049] The handle 21 is swung inward, and the handle 21 drives the first transmission member 25, the second transmission member 26 and the sealing member 24 to move in sequence, so that the sealing member 24 seals the first discharge port, thereby stopping the discharge of ice cream or smoothie.

[0050] A stable transmission chain is formed by the cascade design of the first transmission member 25 and the second transmission member 26. This design not only enhances the stability of the transmission, but also makes the movement of the sealing member 24 during the opening and closing process more stable and accurate.

[0051] The transmission assembly 23 also includes a return torsion spring 27 , which includes a winding portion and a transmission portion from top to bottom. The winding portion is wound around the first hinge point of the handle 21 , and the transmission portion is fixedly connected to the front side of the second transmission member 26 .

[0052] When the handle 21 is swung outward, the rear end of the handle 21 tilts upward, causing the first transmission member 25 to move upward, thereby driving the rear end of the second transmission member 26 upward. Simultaneously, the return torsion spring 27 deforms under the action of the handle 21, and the transmission unit drives the front end of the second transmission member 26 upward. At this point, both the front and rear ends of the second transmission member 26 are subjected to an upward force, causing it to move the sealing member 24 upward, ensuring that the sealing member 24 opens the second discharge port.

[0053] When the staff releases the handle 21 and the handle 21 returns to its original position, the reset torsion spring 27 is reset, and the first transmission member 25 moves downward under the action of the handle 21, so that the second transmission member 26 moves downward under the action of the reset torsion spring 27 and the first transmission member 25, thereby driving the sealing member 24 to move downward and close the second discharge port.

[0054] The refrigeration and stirring assembly 4 also includes a cooling tube, which is looped around the outside of the freezing cylinder 42. As the propeller 41 inside the freezing cylinder 42 stirs the ice cream or smoothie ingredients, the cooling tube simultaneously operates, rapidly removing heat from the outer wall of the freezing cylinder 42 through heat conduction, thereby accelerating the cooling and solidification of the ice cream or smoothie ingredients. This integrated internal and external cooling method significantly improves overall cooling efficiency and shortens the ice cream or smoothie production cycle.

[0055] Furthermore, the cooling tubes are arranged around the outside of the freezing cylinder 42, ensuring that all parts of the freezing cylinder 42 receive a uniform cooling effect. This design avoids uneven temperature distribution inside the freezing cylinder 42, which may cause variations in the texture of the ice cream or smoothie, thereby ensuring the consistency of the quality and taste of the finished ice cream or smoothie.

[0056] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
