Description

Technical Field

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

[0002] As a device that can turn fruit juice into a melted drink, the snow melt machine is widely used in homes, cold drink shops, dessert shops and other places. Its main function is to mix juice and sugar in a certain proportion and then make smoothies.

[0003] The snow melter is equipped with a refrigeration cylinder, agitator, motor, and compressor. The refrigeration cylinder holds the raw materials; the agitator is a spiral structure, rotatably mounted inside the refrigeration cylinder, and the motor drives the agitator. The agitator is equipped with a coiled-tube evaporator, which is a spiral copper tube used to transmit refrigerant; and the compressor provides refrigerant to the evaporator. When the snow melter is in operation, the blended raw materials are first placed in the refrigeration cylinder. The motor and compressor are then started, and the compressor delivers refrigerant to the evaporator on the agitator, exchanging heat with the raw materials in the refrigeration cylinder. The motor then drives the agitator to rotate, stirring the raw materials in the refrigeration cylinder evenly and achieving uniform heat exchange. Once the shaved ice is made, the agitator pushes the formed shaved ice out of the outlet.

[0004] In the above method, the continuous rotation of the blender in one direction leads to significant drawbacks in the production of smoothies. During the smoothie production process, as the ingredients transform from liquid to solid, the continuous unidirectional rotation of the blender will push some of the ingredients that are about to form closer to the discharge port, causing these ingredients to no longer contact the evaporator, reducing the quality and efficiency of the smoothie production and increasing customer complaints. In addition, when the amount of ingredients added to the refrigeration cylinder is small, the continuous unidirectional rotation of the blender will also prevent the ingredients from fully contacting the entire evaporator, reducing the efficiency of the smoothie production. Summary of the Invention

[0045] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts in the drawings or descriptions are numbered the same. Implementations not shown or described in the drawings are known to those of ordinary skill in the art. In the description of this application, the terms "first," "second," etc. are used solely to distinguish descriptions and are not to be construed as indicating or implying relative importance.

[0046] Example 1

[0047] Please refer to Figures 1-4 , the 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 are not described here in detail. This embodiment only introduces the structure of the snow melting machine related to the control method. Figure 4 As shown, the snow melter is equipped with a refrigeration cylinder 110, a stirrer 120, a motor 130, and a compressor 140. The refrigeration cylinder 110 is used to hold the raw materials and has a discharge port 111 at one end. The stirrer 120 is a spiral structure and is rotatably mounted within the refrigeration cylinder 110, while the motor 130 is used to drive the stirrer 120. The stirrer 120 is equipped with a coiled-tube evaporator, which is a spiral copper tube used to transmit refrigerant. The compressor 140 is used to provide refrigerant to the evaporator.

[0048] Furthermore, motor 130 is equipped with a current sensor for detecting the current value, as well as a control structure for controlling the rotational direction of the output shaft of motor 130. A temperature sensor is provided within refrigeration cylinder 110 to detect the temperature of the raw material within refrigeration cylinder 110. Temperature sensors can be installed in multiple locations within refrigeration cylinder 110, such as one at each end and one in the middle. When calculating the material temperature, the average value of the values ​​detected by all temperature sensors can be used as the material temperature.

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

[0050] S100, in response to the working mode selected by the user, starting the motor 130 and the compressor 140, and obtaining the current value of the motor 130 and the material temperature value of the raw material added to the refrigeration cylinder 110;

[0051] S200 , based on the working mode, the current value, and the material temperature value, switching the rotation direction of the output shaft of the motor 130 , and determining whether the shaved ice is ready.

[0052] In the above embodiment, the rotation direction of the output shaft of motor 130 and the determination of whether the shaved ice is ready are controlled based on the evaluation of three reference variables: the operating mode, the current value of motor 130, and the temperature of the raw materials. It will be appreciated that the output shaft of motor 130 is connected to blender 120, and the current value of motor 130 is related to the load of motor 130, which is related to the resistance experienced by blender 120, which in turn is related to the state of the raw materials. Therefore, the current value of motor 130 is directly related to the state of the raw materials. In a specific operating mode, the state of the raw materials can be determined by the current value. The rotation direction of the output shaft of motor 130, and thus the direction of the blender 120, is then switched based on the current feedback. This allows raw materials that are nearly formed and unable to contact the evaporator to be pushed back to a position where they can contact the evaporator, allowing these materials to quickly form into shaved ice, thereby improving the quality and efficiency of shaved ice production.

[0053] In addition, when the amount of raw materials is small, by switching the rotation direction of the stirrer 120, the small amount of raw materials can fully and effectively contact the evaporator, thereby improving the quality and efficiency of shaved ice making.

[0054] The following application of this control method to a snow melter explains each of the above steps in detail as follows:

[0055] In step 100, the working mode can be set based on the amount of raw materials added to the refrigeration cylinder 110, and the working mode is preset with control parameters, which include but are not limited to current thresholds and material temperature thresholds. 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 raw materials. For example, the amount of raw materials in the small-material mode is set to 0-0.5L, and the amount of raw materials in the multi-material mode is set to 0.5-1L. Users can select a specific working mode based on the amount of raw materials they blend. Of course, a liquid injection meter can also be installed on the snow melter to automatically detect the amount of raw materials added to the refrigeration cylinder 110, and then automatically select the corresponding working mode based on the detected amount of raw materials.

[0056] Each working mode is preset with corresponding control parameters, which include but are not limited to current threshold, material temperature threshold and running time. Among them, the current threshold can be used as an important parameter to measure the resistance of the blender 120. According to this parameter, the appropriate time can be selected to switch the direction of the motor 130; and the material temperature threshold can be used as an important parameter to determine whether the shaved ice is formed; the running time mainly refers to the interval time between two adjacent running steps in the corresponding working mode. For the small material mode, due to the small amount of raw materials, the current threshold can be set to a smaller value, such as 0.1-0.2A; for the multi-material mode, due to the large amount of raw materials, the current threshold can be set to a larger value, such as 0.3-0.5A. The material temperature threshold of the two working modes is the same. This embodiment does not make specific restrictions on the current threshold, material temperature threshold and running time. The specific values ​​can be determined based on the comparison of multiple experiments.

[0057] After selecting the operating mode, the snow melter also needs to perform a self-test. The snow melter will automatically check whether there are any problems with the electrical components of the machine. If there are any problems, the staff will be notified to repair them in a timely manner. If there are no problems, the motor 130 and compressor 140 will be started. The motor 130 will drive the stirrer 120 to rotate, stirring the raw materials in the refrigeration cylinder 110. The compressor 140 will supply refrigerant to the evaporator on the stirrer 120, cooling the raw materials in the refrigeration cylinder 110.

[0058] In step 200, the state of the raw materials is determined by evaluating the three reference quantities of the working mode, the current value of the motor 130, and the temperature value of the raw materials, and the rotation direction of the output shaft of the motor 130 is switched according to the feedback of the current value, thereby switching the rotation direction of the agitator 120. The raw materials that are about to be formed and cannot contact the evaporator and are accumulated at one end of the refrigeration cylinder 110 can be pushed in the opposite direction to a position where they contact the evaporator, so that this part of the raw materials can be quickly formed into shaved ice, thereby improving the quality and efficiency of shaved ice production.

[0059] like Figure 2 As shown, in a possible embodiment, the working mode includes a multi-ingredient mode. In the multi-ingredient mode, switching the rotation direction of the output shaft of the motor 130 and determining whether the shaved ice is ready are performed according to the working mode, the current value, and the material temperature value. The steps include:

[0060] S211, when the motor 130 is started, controlling the output shaft of the motor 130 to rotate clockwise;

[0061] S212, after the motor 130 has run for a first period of time, switching the rotation direction of the output shaft of the motor 130 so that the output shaft of the motor 130 rotates counterclockwise;

[0062] S213, periodically determining whether the current value reaches the current threshold value in the multi-material mode, and determining whether the material temperature value reaches the material temperature threshold value in the multi-material mode;

[0063] S214: If the current value reaches the current threshold and the material temperature reaches the material temperature threshold, the shaved ice is formed and the compressor 140 is turned off;

[0064] S215 , switching the rotation direction of the output shaft of the motor 130 to rotate clockwise, and opening the discharge port 111 of the refrigeration cylinder 110 to deliver the formed shaved ice.

[0065] Through the above-mentioned embodiment, when a large amount of raw materials are added, the raw materials that are about to be formed and cannot contact the evaporator and are accumulated at one end of the discharge port 111 of the refrigeration cylinder 110 can be pushed back to a position in contact with the evaporator, so that this part of the raw materials can be quickly formed into shaved ice, thereby improving the efficiency and quality of shaved ice production.

[0066] The following are detailed descriptions of each of the above steps:

[0067] In step S211, 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 by the stirrer 120, but also have a tendency to move toward the discharge port 111.

[0068] In step S212, after the motor 130 has been running for a first period of time, the raw materials in the refrigeration cylinder 110 are about to be formed into shaved ice, and some of the raw materials that are about to be formed are pushed to the end of the discharge port 111 by the blender 120 and no longer come into contact with the evaporator on the blender 120. In this state, the rotation direction of the output shaft of the motor 130 is switched, so that the output shaft of the motor 130 rotates counterclockwise, thereby driving the blender 120 to rotate counterclockwise, and the raw materials that are about to be formed and cannot come into contact with the evaporator and are accumulated at the end of the discharge port 111 of the refrigeration cylinder 110 are pushed in the opposite direction to a position where they come into contact with the evaporator, so that these raw materials are quickly formed into shaved ice, thereby improving the quality and efficiency of shaved ice production.

[0069] It should be noted that the above-mentioned first duration is one of the parameters of the operating duration in the multi-material mode. This embodiment does not specifically limit the specific value of the first duration, and it is calibrated by specific experiments.

[0070] In another embodiment, in step S212, the secondary current value in the multi-ingredient mode can be set, instead of the first operating time of motor 130, as a condition for switching the rotation direction of the output shaft of motor 130. Specifically, when the current value reaches the secondary current value, the rotation direction of the output shaft of motor 130 is switched, causing the output shaft of motor 130 to rotate counterclockwise. It is understood that when the ingredients are about to be formed into a smoothie, the resistance encountered by blender 120 increases, causing the current value of motor 130 to increase. Therefore, the secondary current value can be set as a condition for switching the rotation direction of the output shaft of motor 130.

[0071] In step S213, the current threshold and material temperature threshold in the multi-ingredient mode correspond to the state in which the raw materials are fully formed into shaved ice. Using the dual judgment criteria of current value and material temperature value to determine whether the shaved ice is formed can more accurately determine whether the shaved ice is formed. If both judgment conditions cannot be met simultaneously, it means that the raw materials are not fully formed into shaved ice, or the raw materials are partially formed. If the raw materials are partially formed, it is most likely that the raw materials have been pushed to the end and are about to be formed. In this state, continuing to rotate the agitator 120 counterclockwise can also bring this part of the raw materials to the position where it contacts the evaporator.

[0072] In addition, the cycle judgment time can be set to a relative proofreading time, such as 0.5-1 minute, to improve 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 shaved ice is formed. At this time, the compressor 140 is turned off in time and no refrigerant is supplied to the evaporator to prevent the shaved ice from continuing to cool and causing the shaved ice to form ice cubes.

[0074] In step S215, the rotation direction of the output shaft of the motor 130 is switched to rotate clockwise, thereby driving the blender 120 to rotate clockwise. The discharge port 111 of the refrigeration cylinder 110 is opened, and the shaved ice is delivered from the discharge port 111 by the clockwise rotating blender 120. Finally, the motor 130 is turned off, and the shaved ice making process is completely completed.

[0075] like Figure 3 As shown, in a possible embodiment, the working mode includes a low-material mode. In the low-material mode, switching the rotation direction of the output shaft of the motor 130 and determining whether the shaved ice is ready are performed according to the working mode, the current value, and the material temperature value. The steps include:

[0076] S221, when the motor 130 is started, controlling the output shaft of the motor 130 to rotate clockwise;

[0077] S222, when the current value reaches the current threshold in the low-feed mode, switching the rotation direction of the output shaft of the motor 130 so that the output shaft of the motor 130 rotates counterclockwise;

[0078] S223, after the motor 130 has run for a second time, switching the rotation direction of the output shaft of the motor 130 so that the output shaft of the motor 130 rotates clockwise;

[0079] S224, determining whether the material temperature reaches the material temperature threshold in the low-material mode;

[0080] S225: If the material temperature 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 deliver the formed shaved ice;

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

[0082] Through the above-mentioned embodiment, when a relatively small amount of raw materials is added, not only can the raw materials that are about to be formed and cannot contact the evaporator and are accumulated at one end of the discharge port 111 of the refrigeration cylinder 110 be pushed in the opposite direction to the position in contact with the evaporator, so that this part of the raw materials can be quickly formed into shaved ice, but the raw materials can also be fully in contact with the evaporator, thereby improving the efficiency and quality of shaved ice production.

[0083] The following are detailed descriptions of each of the above steps:

[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 by the stirrer 120, but also have a tendency to move toward the discharge port 111.

[0085] In step S222, the current threshold in the small-material mode corresponds to the state in which the raw materials are initially formed into shaved ice. When the current value of the motor 130 reaches the current threshold in the small-material mode, it indicates that the raw materials are initially formed into shaved ice. At this time, the rotation direction of the output shaft of the motor 130 is switched so that the output shaft of the motor 130 rotates counterclockwise, thereby driving the agitator 120 to rotate counterclockwise. On the one hand, the raw materials that are about to be formed and cannot contact the evaporator and are accumulated at one end of the discharge port 111 of the refrigeration cylinder 110 can be pushed in the opposite direction to a position in contact with the evaporator, so that this part of the raw materials can be quickly formed into shaved ice. On the other hand, the raw materials can also be fully stirred so that the raw materials are fully in contact with the evaporator, thereby improving the efficiency and quality of shaved ice production.

[0086] In step S223, in order to ensure that the raw materials are fully in contact with the evaporator and to facilitate the subsequent formation of shaved ice to be delivered from the discharge port 111, after the motor 130 runs for a second period of time, 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 output shaft to rotate clockwise.

[0087] It should be noted that the second duration is one of the parameters of the operating duration in the low-feed mode. This embodiment does not specifically limit the specific value of the second duration, and it is calibrated by specific experiments.

[0088] In step S224, in the small material mode, since the current value in the previous step has reached the current threshold and the added raw materials are relatively small, 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 reaches the material temperature threshold, it can be determined that the shaved ice is formed. At this time, the compressor 140 is turned off in time and no refrigerant is supplied to the evaporator to prevent the shaved ice from continuing to cool and causing the shaved ice to form ice cubes.

[0090] In step S226, if the material temperature value does not reach the material temperature threshold, it indicates that the raw material has not been completely formed into shaved ice, and the cycle control strategy is executed to control the blender 120 to rotate forward and reverse through the motor 130 to improve the efficiency of shaved ice forming.

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

[0092] S2261, switching the rotation direction of the output shaft of the motor 130 so that the output shaft of the motor 130 rotates counterclockwise;

[0093] S2262: When the motor 130 runs for a third time, switching the rotation direction of the output shaft of the motor 130 so that the output shaft of the motor 130 rotates clockwise;

[0094] S2263, determining whether the material temperature reaches the material temperature threshold in the low-material mode;

[0095] S2264: If the material temperature 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 deliver the formed shaved ice;

[0096] S2265: If the material temperature value does not reach the material temperature threshold, re-execute the cycle control strategy.

[0097] Through the above-mentioned cyclic 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, the efficiency of smoothie forming can be improved by cyclically controlling the forward and reverse rotation of the blender 120.
