Description

Technical Field

[0001] The present invention relates to the technical field of snow cone machines, and more particularly, to a control method, a control device, an electronic device, a snow cone machine, and a storage medium. Background Art

[0002] As a device that can make fruit juice into a snow cone - like beverage, the snow cone machine is widely used in places such as homes, cold drink shops, and dessert shops. Its main function is to mix fruit juice and sugar in a certain proportion and then make shaved ice.

[0003] The snow cone machine is provided with structures such as a refrigeration cylinder, a stirrer, a motor, and a compressor. Among them, the refrigeration cylinder is used to hold raw materials; the stirrer is a spiral structure and is rotatably installed in the refrigeration cylinder, and the motor is used to drive the stirrer to rotate; the stirrer is provided with a tube - in - tube evaporator, and the tube - in - tube evaporator is a spiral copper tube for transmitting refrigerant; the compressor is used to provide refrigerant for the evaporator. When the snow cone machine works, first, the prepared raw materials are put into the refrigeration cylinder, then the motor and the compressor are started. The compressor delivers refrigerant to the evaporator on the stirrer to exchange heat with the raw materials in the refrigeration cylinder, and the motor drives the stirrer to rotate to evenly stir the raw materials in the cold cylinder to achieve uniform heat exchange. After the shaved ice is made, the formed shaved ice is pushed out from the discharge port by the stirrer.

[0004] In the above - mentioned method, since the stirrer rotates continuously in one direction, there are significant drawbacks in the production of shaved ice. During the production of shaved ice, as the raw materials change from liquid to solid, the continuously rotating stirrer in one direction will push some of the almost - formed raw materials to the end near the discharge port, resulting in these almost - formed raw materials no longer contacting the evaporator, reducing the quality and efficiency of shaved ice production and increasing the customer complaint rate. In addition, when the amount of raw materials added to the refrigeration cylinder is small, the continuously rotating stirrer in one direction will also cause the raw materials not to fully contact the entire evaporator, reducing the efficiency of shaved ice production. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide a control method, a control device, an electronic device, a snow cone machine, and a storage medium, which can improve the efficiency and quality of shaved ice production.

[0026] Determine whether the material temperature value reaches the material temperature threshold in the under-material mode;

[0027] If the material temperature value reaches the material temperature threshold, the smoothie is formed, the compressor is turned off, and the discharge port of the refrigeration cylinder is opened to send out the formed smoothie;

[0046] Embodiment 1

[0047] Please refer to Figures 1 - 4 For this, an embodiment of the present application provides a control method, which is applied to a snow melting machine. The snow melting machine is a prior art, and its specific structure and principle will not be elaborated here. This embodiment only introduces the structure related to the control method on the snow melting machine. As Figure 4 shown, structures such as a refrigeration cylinder 110, a stirrer 120, a motor 130, and a compressor 140 are provided on the snow melting machine. Among them, the refrigeration cylinder 110 is used to hold raw materials, and a discharge port 111 is provided at one end; the stirrer 120 is a spiral structure and is rotatably installed in the refrigeration cylinder 110, and the motor 130 is used to drive the stirrer 120 to rotate; a tube-in-tube evaporator is provided on the stirrer 120, and the tube-in-tube evaporator is a spiral copper tube for transmitting refrigerant; and the compressor 140 is used to provide refrigerant for the evaporator.

[0048] In addition, a current sensor for detecting the current value is provided on the motor 130, and a control structure for controlling the rotation direction of the output shaft of the motor 130. A temperature sensor is provided in the refrigeration cylinder 110 for detecting the temperature value of the raw materials in the refrigeration cylinder 110. Temperature sensors can be installed at multiple positions in the refrigeration cylinder 110, for example, one is installed at both ends and in the middle. When calculating the temperature value of the raw materials, the average value detected by all temperature sensors can be taken as the temperature value of the raw materials.

[0049] As Figure 1 shown, in this embodiment, the control method includes the following steps:

[0050] S100. In response to the working mode selected by the user, start the motor 130 and the compressor 140, and obtain the current value of the motor 130 and the temperature value of the raw materials added to the refrigeration cylinder 110;

[0051] S200. Based on the working mode, the current value, and the temperature value, switch the rotation direction of the output shaft of the motor 130, and determine whether the shaved ice is completely made.

[0052] In the above-described embodiments, based on the evaluation of three reference quantities, namely the working mode, the current value of the motor 130, and the temperature value of the raw material, the rotation direction of the output shaft of the motor 130 is controlled, and it is determined whether the smoothie is completely made. It can be understood that the output shaft of the motor 130 is connected to the blender 120. The current value of the motor 130 is related to the load of the motor 130. The load of the motor 130 is related to the resistance received by the blender 120, and the resistance received by the blender 120 is related to the state of the raw material. Therefore, the current value of the motor 130 is directly related to the state of the raw material. In a specific working mode, the state of the raw material can be judged by the current value, and then the rotation direction of the output shaft of the motor 130 can be switched according to the feedback of the current value, so as to switch the rotation direction of the blender 120. It is possible to reverse-push the raw material that is about to take shape and cannot contact the evaporator at one end of the discharge port 111 of the refrigeration cylinder 110 to a position where it contacts the evaporator, so that this part of the raw material is quickly formed into a smoothie, thereby improving the quality and efficiency of smoothie production.

[0053] In addition, when the amount of the raw material is small, by switching the rotation direction of the blender 120, it is also possible to make the small amount of raw material fully and effectively contact the evaporator, thereby improving the quality and efficiency of smoothie production.

[0054] Next, this control method will be applied to a snow melter, and each of the above steps will be elaborated in detail as follows:

[0055] In step 100, the working mode can be set based on the amount of raw material added to the refrigeration cylinder 110. Control parameters are preset in the working mode, and the control parameters include but are not limited to current thresholds and temperature thresholds of the raw material. In this embodiment, the working mode includes a multi-material mode and a small-material mode, and these two modes are mainly distinguished according to the amount of the raw material. For example, the amount of the raw material in the small-material mode is set to 0 - 0.5 L, and the amount of the raw material in the multi-material mode is set to 0.5 - 1 L. The user can select a specific working mode according to the amount of the raw material they blend. Of course, a liquid injection measuring instrument can also be installed on the snow melter to automatically detect the amount of raw material added to the refrigeration cylinder 110, and then automatically select the corresponding working mode according to the detected amount of the raw material.

[0056] For each working mode, corresponding control parameters are preset, and the control parameters include but are not limited to current threshold, material temperature threshold, and operation duration. Among them, the current threshold can be an important parameter to measure the resistance received by the stirrer 120. According to this parameter, an appropriate timing can be selected to switch the rotation direction of the motor 130; while the material temperature threshold can be an important parameter for whether the smoothie is formed; the operation duration mainly refers to the interval time between two adjacent operation steps in the corresponding working mode. For the less material mode, since the amount of raw materials is small, the current threshold can be set relatively small, such as 0.1 - 0.2 A; for the more material mode, since the amount of raw materials is large, the current threshold can be set relatively large, such as 0.3 - 0.5 A. The material temperature thresholds of the two working modes are the same. In this embodiment, no specific limitations are imposed on the current threshold, material temperature threshold, and operation duration, and their specific values can be determined according to the comparison of multiple experiments.

[0057] In addition, after the working mode is selected, machine self - inspection is also required, and the snow - melting machine automatically detects whether there are problems with the electrical components on the machine. If there are problems, it can remind the staff to repair them in time; if there are no problems, the motor 130 and the compressor 140 are started. The motor 130 drives the stirrer 120 to rotate, and the raw materials in the refrigeration cylinder 110 are stirred evenly; the compressor 140 transports refrigerant to the evaporator on the stirrer 120 to refrigerate the raw materials in the refrigeration cylinder 110.

[0058] In step 200, by judging the three reference quantities of the working mode, the current value of the motor 130, and the material temperature value of the raw materials, it is determined which state the raw materials are in, and according to the feedback of the current value, the rotation direction of the output shaft of the motor 130 is switched, so as to switch the rotation direction of the stirrer 120, which can push the raw materials that are about to be formed and cannot contact the evaporator at one end of the refrigeration cylinder 110 in the reverse direction to the position where they contact the evaporator, so that this part of the raw materials can be quickly formed into smoothies, thereby improving the quality and efficiency of smoothie production.

[0059] As Figure 2 shown, in a possible embodiment, the working mode includes the more material mode. In the more material mode, according to the working mode, the current value, and the material temperature value, the rotation direction of the output shaft of the motor 130 is switched, and it is judged whether the smoothie is made, including the following steps:

[0060] S211. When starting the motor 130, control the output shaft of the motor 130 to rotate clockwise;

[0061] S212. After the motor 130 runs for the first duration, switch the rotation direction of the output shaft of the motor 130 to make the output shaft of the motor 130 rotate counterclockwise;

[0062] S213. Periodically determine whether the current value reaches the current threshold in the multi - material mode, and determine whether the material temperature value reaches the material temperature threshold in the multi - material mode;

[0063] S214. If the current value reaches the current threshold and the material temperature value reaches the material temperature threshold, the smoothies are formed, and the compressor 140 is turned off;

[0064] S215. Switch the rotation direction of the output shaft of the motor 130 to make the output shaft of the motor 130 rotate clockwise, and open the discharge port 111 of the refrigeration cylinder 110 to send out the formed smoothies.

[0065] Through the above - mentioned implementation manner, in the case of adding more raw materials, the raw materials that are about to be formed and cannot contact the evaporator and are piled up at one end of the discharge port 111 of the refrigeration cylinder 110 can be reversely pushed to the position in contact with the evaporator, so that this part of the raw materials can be quickly formed into smoothies, thereby improving the efficiency and quality of smoothie production.

[0066] The following elaborates on each of the above steps in detail as follows:

[0067] In step S211, when the motor 130 starts to start, the output shaft of the motor 130 keeps rotating clockwise, thereby driving the stirrer 120 to rotate clockwise. In this state, the raw materials in the refrigeration cylinder 110 can not only be mixed evenly by the stirrer 120, but also have a tendency to move towards the discharge port 111.

[0068] In step S212, when the motor 130 runs for the first duration, the raw materials in the refrigeration cylinder 110 are about to be formed into smoothies, and some of the raw materials that are about to be formed will be pushed by the stirrer 120 to one end of the discharge port 111 and will no longer contact the evaporator on the stirrer 120. In this state, switch the rotation direction of the output shaft of the motor 130 to make the output shaft of the motor 130 rotate counterclockwise, thereby driving the stirrer 120 to rotate counterclockwise, and reversely push the raw materials that are about to be formed and cannot contact the evaporator and are piled up at one end of the discharge port 111 of the refrigeration cylinder 110 to the position in contact with the evaporator, so that this part of the raw materials can be quickly formed into smoothies, thereby improving the quality and efficiency of smoothie production.

[0069] It should be noted that the above - mentioned first duration is one of the parameters in the operation duration in the multi - material mode. In this embodiment, the specific value of the first duration is not specifically limited and is calibrated by specific experiments.

[0070] In another embodiment, in step S212, instead of running the motor 130 for the first duration, the rotation direction of the output shaft of the motor 130 can be switched by setting the secondary current value in the multi-material mode. Specifically, when the current value reaches the secondary current value, the rotation direction of the output shaft of the motor 130 is switched so that the output shaft of the motor 130 rotates counterclockwise. It can be understood that when the raw material is about to be formed into smoothies, the resistance received by the stirrer 120 increases, causing the current value of the motor 130 to increase. Therefore, the secondary current value can be set as the condition for switching the rotation direction of the output shaft of the motor 130.

[0071] In step S213, the current threshold and the material temperature threshold in the multi-material mode can correspond to the state where the raw material is completely formed into smoothies. By using the dual judgment conditions of the current value and the material temperature value to judge whether the smoothies are formed, it is possible to more accurately judge whether the smoothies are formed. If these two judgment conditions cannot be achieved simultaneously, it means that the raw material is not all formed into smoothies, or there is still some part of the raw material that is not formed into smoothies. If there is still some part of the raw material that is not formed, it is very likely that it is the part of the raw material that is about to be formed and is pushed to the end. In this state, continuing to rotate the stirrer 120 counterclockwise can also bring this part of the raw material to the position in contact with the evaporator.

[0072] In addition, the time for periodic judgment can be set to a relatively calibrated duration, such as 0.5 - 1 minute, so as to improve the production efficiency.

[0073] In step S214, when the current value reaches the current threshold and the material temperature value reaches the material temperature threshold, it can be determined that the smoothies are formed. At this time, the compressor 140 is promptly turned off, and refrigerant is no longer supplied to the evaporator to prevent the smoothies from continuing to cool and forming into ice cubes.

[0074] In step S215, the rotation direction of the output shaft of the motor 130 is switched so that the output shaft of the motor 130 rotates clockwise, thereby driving the stirrer 120 to rotate clockwise, and the discharge port 111 of the refrigeration cylinder 110 is opened. The smoothies are sent out from the discharge port 111 by the clockwise rotating stirrer 120. Finally, the motor 130 is turned off, and the smoothies production process is completely completed.

[0075] As Figure 3 shown, in a possible embodiment, the working mode includes a small-material mode. In the small-material mode, according to the working mode, the current value, and the material temperature value, the rotation direction of the output shaft of the motor 130 is switched, and it is determined whether the smoothies are completely made, including the following steps:

[0076] S221. When the motor 130 is started, control the output shaft of the motor 130 to rotate clockwise;

[0077] S222. When the current value reaches the current threshold in the less - material mode, switch the rotation direction of the output shaft of the motor 130 so that the output shaft of the motor 130 rotates counter - clockwise;

[0078] S223. When the motor 130 runs for a second duration, switch the rotation direction of the output shaft of the motor 130 so that the output shaft of the motor 130 rotates clockwise;

[0079] S224. Determine whether the material temperature value reaches the material temperature threshold in the less - material mode;

[0080] S225. If the material temperature value reaches the material temperature threshold, the smoothies are formed. Turn off the compressor 140 and open the discharge port 111 of the refrigeration cylinder 110 to send out the formed smoothies;

[0081] S226. If the material temperature value does not reach the material temperature threshold, execute the cyclic control strategy.

[0082] Through the above - mentioned implementation manner, in the case of adding less raw materials, not only can the raw materials that are about to be formed and cannot contact the evaporator and are piled up at one end of the discharge port 111 of the refrigeration cylinder 110 be pushed reversely to the position in contact with the evaporator, so that this part of the raw materials can be quickly formed into smoothies, but also the raw materials can be fully in contact with the evaporator, thereby improving the efficiency and quality of smoothie production.

[0083] The following elaborates on each of the above steps in detail as follows:

[0084] In step S221, when the motor 130 starts, the output shaft of the motor 130 keeps rotating clockwise, thereby driving the stirrer 120 to rotate clockwise. In this state, the raw materials in the refrigeration cylinder 110 can not only be mixed evenly by the stirrer 120, but also have a tendency to move towards the discharge port 111.

[0085] In step S222, the current threshold in the less - material mode corresponds to the state where the raw materials are initially formed into smoothies. When the current value of the motor 130 reaches the current threshold in the less - material mode, it indicates that the raw materials are initially formed into smoothies. At this time, switch the rotation direction of the output shaft of the motor 130 so that the output shaft of the motor 130 rotates counter - clockwise, thereby driving the stirrer 120 to rotate counter - clockwise. On the one hand, it can push the raw materials that are about to be formed and cannot contact the evaporator and are piled up at one end of the discharge port 111 of the refrigeration cylinder 110 reversely to the position in contact with the evaporator, so that this part of the raw materials can be quickly formed into smoothies. On the other hand, it can also fully stir the raw materials, making the raw materials fully in contact with the evaporator, thereby improving the efficiency and quality of smoothie production.

[0086] In step S223, in order to enable the raw materials to fully contact the evaporator and facilitate the subsequent formed shaved ice to be sent out from the discharge port 111, after the motor 130 runs for a second duration, the rotation direction of the output shaft of the motor 130 is switched to make the output shaft of the motor 130 rotate clockwise, thereby driving the output shaft to rotate clockwise.

[0087] It should be noted that the second duration is one of the parameters in the operation duration in the less-material mode. In this embodiment, the specific value of the second duration is not specifically limited and is calibrated by specific experiments.

[0088] In step S224, in the less-material mode, since the current value has reached the current threshold in the previous steps and the added raw materials are relatively few, therefore, in this step, only the material temperature value can be used to determine whether the raw materials are formed into shaved ice.

[0089] In step S225, if the material temperature value reaches the material temperature threshold, it can be determined that the shaved ice is formed. At this time, the compressor 140 is promptly turned off, and refrigerant is no longer supplied to the evaporator to prevent the shaved ice from continuing to cool and resulting in the formation of ice cubes.

[0090] In step S226, if the material temperature value does not reach the material temperature threshold, it indicates that the raw materials have not been fully formed into shaved ice. Then, a cyclic control strategy is executed, and the stirrer 120 is controlled by the motor 130 to rotate forward and backward cyclically to improve the efficiency of forming the shaved ice.

[0091] As Figure 3 shown, in this embodiment, the cyclic control strategy includes:

[0092] S2261. Switch the rotation direction of the output shaft of the motor 130 to make the output shaft of the motor 130 rotate counterclockwise;

[0093] S2262. When the motor 130 runs for a third duration, switch the rotation direction of the output shaft of the motor 130 to make the output shaft of the motor 130 rotate clockwise;

[0094] S2263. Judge whether the material temperature value reaches the material temperature threshold in the less-material mode;

[0095] S2264. If the material temperature value reaches the material temperature threshold, the shaved ice is formed, the compressor 140 is turned off, and the discharge port 111 of the refrigeration cylinder 110 is opened to send out the formed shaved ice;

[0096] S2265. If the material temperature value does not reach the material temperature threshold, the cyclic control strategy is executed again.

[0097] Through the above-mentioned loop control strategy, in the low-material mode, when the current value of the motor 130 has reached the current threshold and the material temperature value has not reached the material temperature threshold, by cyclically controlling the forward and reverse rotation of the stirrer 120, the efficiency of smoothie formation can be improved.
