Description

Technical Field

[0001] The present invention relates to the technical field of food processing equipment, and in particular, to a control method for a food processor, a control device, a food processor, and a readable storage medium. Background Art

[0002] In related technologies, cold-brewed beverages require cold-steeping foods such as coffee / tea for 6 to 20 hours to effectively extract flavor substances such as tea polyphenols, catechins, and caffeine in the foods. The production time is too long and the production efficiency is low, and users cannot drink them in a short time. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, the first aspect of the present invention provides a control method for a food processor.

[0005] The second aspect of the present invention further provides a control device.

[0006] The third aspect of the present invention further provides a food processor.

[0007] The fourth aspect of the present invention further provides a readable storage medium.

[0008] In view of this, the first aspect of the present invention proposes a control method for a food processor, including: in response to a start instruction of the food processor, controlling a pressure device to form a preset pressure difference in a containing cavity, and controlling an ultrasonic generating device to operate according to preset ultrasonic parameters.

[0009] In the control method for a food processor provided by the present invention, when a user needs to process food, for example, make a cold-brewed beverage, the user can first add the ingredients to be processed and liquid into the containing cavity of the food processor, and then issue a start instruction of the food processor by operating the food processor. The food processor responds to the instruction to process the ingredients to be processed, that is, the start instruction, and starts to process the ingredients. Among them, the food in the containing cavity includes the ingredients to be processed and the liquid for soaking the ingredients, and the ingredients to be processed include coffee, flowers, fruits, tea, traditional Chinese medicine, wine, etc.

[0010] Further, after the food processor is started, the pressure device of the food processor is controlled to operate to change the pressure in the accommodation cavity to form a preset pressure difference, and the ultrasonic generating device of the food processor is controlled to operate according to preset ultrasonic parameters to generate ultrasonic waves to disturb the food in the accommodation cavity. On the one hand, by using the pressure difference after the pressure change, a changing pressure is applied to the food in the accommodation cavity, thereby opening the internal channels of the to-be-processed food materials and accelerating the entry of liquid into the internal voids of the food materials. This not only speeds up the extraction of flavor components from the food materials but also facilitates the better transmission of ultrasonic waves inside the food materials, enhancing the dissolution of nutrient components in the food materials and greatly shortening the required time while ensuring the food processing effect. On the other hand, by utilizing the strong cavitation effect, mechanical vibration, perturbation effect, high acceleration, emulsification, diffusion, fragmentation, and stirring effects generated by the radiation pressure of the ultrasonic waves emitted by the ultrasonic generating device, the movement frequency and speed of substance molecules and the liquid penetration ability are increased, thereby accelerating the entry of nutrient components of the food materials into the water, promoting the leaching of flavor substances, making the aroma and sweetness of the beverage more prominent, reducing the bitter and astringent flavor, effectively improving the food processing speed, shortening the waiting time of the user, and enabling the rapid formation of the required finished product even at normal temperature or low temperature.

[0011] It can be understood that when the start instruction is received, the pressure device and the ultrasonic generating device can start working simultaneously to further shorten the time required for food processing, or they can start working successively to avoid mutual influence between the pressure device and the ultrasonic generating device.

[0012] It should be noted that the food processor includes: a housing, a main body, an ultrasonic generating device, and a pressure device. The main body is provided with an accommodation cavity, and the to-be-processed food materials and liquid can be accommodated in the accommodation cavity. The ultrasonic generating device is arranged on the main body, and at least a part of the ultrasonic generating device extends into the accommodation cavity. The ultrasonic waves generated by the ultrasonic generating device can form a disturbance to the liquid and the to-be-processed food materials, changing the liquid and the to-be-processed food materials from a static state to a flowing state, which can accelerate the dissolution rate of water-soluble substances in the to-be-processed food, speed up the food processing speed, shorten the processing time, reduce the waiting time of the user, enable the user to eat the processed food as soon as possible, and is beneficial to enhancing the competitiveness of the product and improving the user experience of the food processor. The pressure device is arranged in the housing and communicated with the accommodation cavity, and the pressure change in the accommodation cavity is realized through the pressure device, thereby accelerating the entry of liquid or ultrasonic waves into the internal voids of the to-be-processed food materials and accelerating the dissolution of nutrient components in the food materials.

[0013] According to the control method of the food processor provided by the present invention, the following additional technical features may also be included:

[0014] In the above technical solution, further, controlling the pressure device to form a preset pressure difference in the accommodation cavity includes: controlling the pressure device to work periodically according to the preset pressure difference, so that the pressure in the accommodation cavity first increases and then decreases or first decreases and then increases; determining the first working duration during the periodic operation of the pressure device; and closing the pressure device based on the first working duration being greater than or equal to the first preset duration.

[0015] In this technical solution, the pressure device is controlled to work periodically at preset time intervals, so that the pressure in the accommodation cavity first increases and then decreases or first decreases and then increases. Thus, by first applying alternating pressure to the food in the accommodation cavity to open the internal channels of the to-be-processed food materials, not only can the extraction of flavor components of the food materials be accelerated, but also the subsequent ultrasonic waves can be better transmitted inside the food materials, taking into account both the ultrasonic treatment effect and speed, and greatly shortening the waiting time of the user.

[0016] Further, during the operation of the pressure device, record the first working duration accumulated during the periodic operation of the pressure device. When the first working duration is greater than or equal to the first preset duration, it indicates that the pressure change control process of the pressure device is completed, and then control the pressure device to stop working.

[0017] Among them, considering that the pressure device works at a specified time interval, in the case of no timing device, the first working duration during the periodic operation of the pressure device can be determined by the number of starts of the pressure device, the number of cycles of periodic operation, or the pressure change frequency. It should be noted that within one working cycle, the pressure device will start twice. The first start is to increase or decrease the pressure in the accommodation cavity based on the initial pressure to form a preset pressure difference, and the second start is when the pressure in the accommodation cavity returns to the initial pressure.

[0018] Taking the example where the pressure in the accommodating cavity first increases and then decreases, the periodic operation of the pressure control device specifically includes: inflating the accommodating cavity through the pressure control device to increase the pressure in the accommodating cavity to a first pressure threshold, where the first pressure threshold is the sum of the initial pressure of the accommodating cavity (e.g., atmospheric pressure) and a preset pressure difference. When the pressure maintaining duration of the accommodating cavity at the first pressure threshold is greater than or equal to a first duration threshold, the pressure control device is controlled again to restore (decrease) the pressure in the accommodating cavity to the initial pressure. At this time, the number of operating cycles of the pressure control device is incremented by 1, or the number of startup times is incremented by 2 times. Here, the first duration threshold is the pressure maintaining time during the pressure change process of the accommodating cavity and can be reasonably set according to requirements. Of course, the first duration threshold can also be 0, that is, the pressure decreases immediately after increasing. When the duration after the pressure in the accommodating cavity is restored to the initial pressure is greater than or equal to a preset time interval, the above pressure control steps are repeated until the first working duration during the periodic operation of the pressure control device is greater than or equal to a first preset duration. After confirming that the pressure control is completed, the pressure control device is turned off. Taking the example where the pressure in the accommodating cavity first decreases and then increases, the periodic operation of the pressure control device specifically includes: extracting the gas in the accommodating cavity through the pressure control device to reduce the pressure in the accommodating cavity to a second pressure threshold, where the second pressure threshold is the difference between the initial pressure of the accommodating cavity (e.g., atmospheric pressure) and a preset pressure difference. When the pressure maintaining duration of the accommodating cavity at the second pressure threshold is greater than or equal to the first duration threshold, the pressure control device is controlled again to inflate the accommodating cavity to restore (increase) the pressure in the accommodating cavity to the initial pressure. At this time, the number of operating cycles is incremented by 1, or the number of startup times is incremented by 2 times. When the duration after the pressure in the accommodating cavity is restored to the initial pressure is greater than or equal to a preset time interval, the above pressure control steps are repeated until the first working duration during the periodic operation of the pressure control device is greater than or equal to a first preset duration. After confirming that the pressure control is completed, the pressure control device is turned off.

[0019] It can be understood that the increase in the pressure in the accommodating cavity can be achieved through an inflating device or a pressure control valve, and the decrease in the pressure in the accommodating cavity can be achieved through a gas extraction device or a pressure control valve.

[0020] Among them, the first preset duration is the time required for the pressure control steps and can be reasonably set according to the type and weight of the food.

[0021] In any of the above technical solutions, further, controlling the ultrasonic generating device to operate includes: controlling the ultrasonic generating device to operate based on the first working duration being greater than or equal to a second preset duration, where the second preset duration is less than or equal to the first preset duration.

[0022] In this technical solution, when the pressure device and the ultrasonic generating device are started successively, in response to the start instruction of the food processor, the pressure device is started first. When controlling the pressure device to perform pressure control operation on the accommodation cavity, the first working duration accumulated during the periodic operation of the pressure device is recorded. When the first working duration is greater than or equal to the second preset duration, the ultrasonic generating device is started according to the preset ultrasonic parameters, that is, the ultrasonic treatment step is performed during or after the pressure control process of the pressure device. Thus, by applying alternating pressure to the food in the accommodation cavity first, the internal channels of the to-be-processed ingredients are opened, so that the subsequent ultrasonic waves can be better transmitted inside the ingredients, taking into account both the ultrasonic treatment effect and speed, and greatly shortening the waiting time of the user.

[0023] In any of the above technical solutions, further, controlling the operation of the ultrasonic generating device according to the preset ultrasonic parameters includes: controlling the ultrasonic generating device to work continuously or intermittently according to the operation parameters in the preset ultrasonic parameters; determining the second working duration during the operation of the ultrasonic generating device; and based on the second working duration being greater than or equal to the third preset duration in the preset ultrasonic parameters, turning off the ultrasonic generating device.

[0024] In this technical solution, the ultrasonic generating device is started according to the operation parameters (such as ultrasonic power, frequency, etc.) in the preset ultrasonic parameters. The ultrasonic waves emitted by the ultrasonic generating device disturb the to-be-processed ingredients in the accommodation cavity, so that the components in the ingredients will obtain kinetic energy and move, thereby promoting the leaching of flavor substances and at the same time accelerating the rapid dissolution of water-soluble substances into the liquid. And the second working duration of the ultrasonic generating device is timed while the ultrasonic generating device is started. When the second working duration is greater than or equal to the third preset duration in the preset ultrasonic parameters, it indicates that the ultrasonic treatment of the food is completed, and at this time, the ultrasonic generating device is controlled to be turned off. Furthermore, the automatic ultrasonic treatment of the food is realized, which can effectively improve the processing speed, shorten the waiting time of the user, and can quickly form the required food even at normal temperature or low temperature. Moreover, by reasonably setting the ultrasonic parameters, the dissolution of bad flavor components is reduced, making the aroma and sweet taste of the drink more prominent and reducing the bitter and astringent flavor.

[0025] Among them, the preset ultrasonic parameters include the operation parameters of the ultrasonic treatment device and the third preset duration. The third preset duration is the time required for the ultrasonic step, which can be reasonably set according to the type and weight of the food, and the operation parameters are related to the model of the ultrasonic treatment device.

[0026] Further, the working mode of the ultrasonic generating device can be to continuously work at a specified ultrasonic power and frequency, which is beneficial to accelerating the precipitation of flavor substances in the food materials and greatly shortening the processing time required. The working mode of the ultrasonic generating device can also be to work intermittently according to the specified ultrasonic power and the preset on-off ratio, so as to avoid faults such as overheating and damage of the ultrasonic generating device on the basis of ensuring the ultrasonic treatment effect, and effectively extend the service life of the food processor. In addition, for different working modes of the ultrasonic generating device, the total duration required for ultrasonic treatment is different. For example, when working continuously, the total duration is the third preset duration, and when working intermittently, the total duration is the sum of the third preset duration and the intermittent time interval. In any of the above technical solutions, further, controlling the pressure device to form a preset pressure difference in the accommodating cavity includes: based on the second working duration being greater than or equal to the fourth preset duration, controlling the pressure device to form a preset pressure difference in the accommodating cavity, where the fourth preset duration is less than or equal to the third preset duration.

[0027] In this technical solution, considering the penetrability of ultrasonic waves, ultrasonic waves can not only disturb food, but also affect other components in the food processor. To reduce the impact of ultrasonic waves on the food processor, in the case where the ultrasonic generating device and the pressure device are started successively, in response to the start instruction, the ultrasonic generating device is first started according to the preset ultrasonic parameters. When the second working duration of the ultrasonic generating device reaches (is greater than or equal to) the fourth preset duration, the pressure device is then controlled to apply alternating pressure to the food in the accommodating cavity, that is, the pressure control step is performed during or after the ultrasonic treatment process. Thus, first use ultrasonic waves to increase the movement frequency and speed of substance molecules and the liquid penetration ability, accelerate the entry of food nutrient components into water, and then apply alternating pressure to the food in the accommodating cavity to open the internal channels of the food to be processed and accelerate the entry of liquid into the internal voids of the food, accelerating the precipitation of food flavor components. On the one hand, it avoids seriously damaging the food structure when the ultrasonic generating device and the pressure device work simultaneously and affecting the taste of the processed food. On the other hand, by adjusting the pressure instead of ultrasonic treatment, on the basis of accelerating the dissolution rate of water-soluble substances in the food to be processed, the time required for ultrasonic treatment is reduced, and the damage to food crushing and the food processor caused by ultrasonic waves is further reduced.

[0028] In any of the above technical solutions, further, the food processor includes a refrigeration device for cooling the food, and the control method further includes: based on the temperature in the accommodating cavity being greater than the first preset temperature, controlling the refrigeration device to work according to the preset refrigeration parameters so that the temperature of the food is reduced to the first preset temperature.

[0029] In this technical solution, considering that during the food processing process, there are situations where the initial temperature of the liquid added to the food processor is higher than the temperature required by the user, or the liquid temperature rises due to the operation of the ultrasonic generating device. Therefore, during the food processing process, if it is detected that the temperature in the accommodation cavity is greater than the first preset temperature, it indicates that the current food temperature is higher than the temperature required by the user for the food. Then, the refrigeration device of the food processor is controlled to cool the food until the temperature in the accommodation cavity drops to the first preset temperature, and then the refrigeration device is controlled to stop cooling. This enables the food to quickly reach the temperature required by the user, thus taking into account both the food processing efficiency and the taste of the processed food. Moreover, it can avoid the problem of food temperature rise caused by the operation of the ultrasonic generating device, and the required food can be quickly formed at room temperature, meeting the various needs of users for food processing. Among them, the temperature in the accommodation cavity can be approximately regarded as the food temperature.

[0030] Among them, the first preset temperature is the temperature required by the user for the finished product after food processing and can be set as needed.

[0031] It is worth mentioning that the refrigeration device can be started synchronously with the pressure device and the ultrasonic generating device, which is beneficial to reducing the food processing time and enabling the user to obtain the required finished product faster.

[0032] Furthermore, if it is detected that the temperature in the accommodation cavity is less than or equal to the first preset temperature, it indicates that the food temperature has met the user's requirements at this time, and there is no need to start the refrigeration device.

[0033] In any of the above technical solutions, further, controlling the refrigeration device to operate includes: based on the second working duration of the ultrasonic generating device being greater than or equal to the fifth preset duration, controlling the refrigeration device to operate, where the fifth preset duration is less than or equal to the third preset duration in the preset ultrasonic parameters.

[0034] In this technical solution, considering that a lower temperature is not conducive to the dissolution of nutrients. Therefore, the ultrasonic generating device is started first to perform ultrasonic treatment on the ingredients to be processed under the temperature condition that does not affect the dissolution of nutrients. After the second working duration of the ultrasonic generating device is greater than or equal to the fifth preset duration, the refrigeration device is then turned on. This can not only ensure that the temperature does not drop during the ultrasonic treatment process and the ultrasonic treatment effect is better, but also prevent the impact of food temperature rise during the operation of the ultrasonic generating device on the food taste through subsequent cooling treatment.

[0035] Furthermore, when it is detected that the temperature in the accommodation cavity is less than or equal to the first preset temperature, and the second working duration of the ultrasonic generating device is greater than or equal to the third preset duration, and the first working duration of the periodic operation of the pressure device is greater than or equal to the first preset duration, it indicates that the food processing is completed. At this time, a prompt message is output to remind the user to pick up the food in time.

[0036] In any of the above technical solutions, further, the food processor includes a heating device, which controls the pressure device to form a preset pressure difference in the accommodating chamber, and before controlling the ultrasonic generating device to operate according to preset ultrasonic parameters, it also includes: based on the temperature in the accommodating chamber being lower than a second preset temperature, controlling the heating device to operate according to the preset heating parameters to raise the temperature of the food to the second preset temperature.

[0037] In this technical solution, a heating device is also provided in the food processor, and the food in the receiving chamber can be heated by the heating device. Specifically, since too low a temperature is not conducive to the extraction of flavor substances, it seriously affects the food processing efficiency. Therefore, when the temperature of the food is lower than the second preset temperature, the food can be heated by the heating device until the temperature in the receiving chamber is equal to the second preset temperature, and then the heating device is controlled to be turned off, so that the temperature of the food can be quickly raised to the optimal temperature for food processing (the second preset temperature). Thereby, the aroma and sweetness of the drink are more prominent, the bitter flavor is reduced, the food processing effect is effectively enhanced, and the quality of the finished product is improved, and it is also conducive to improving the food processing efficiency.

[0038] Among them, the second preset temperature is a better processing temperature for food, and the second preset temperature can be set according to the type of food to be processed.

[0039] In any of the above technical solutions, further, controlling the operation of the ultrasonic generating device includes: controlling the operation of the ultrasonic generating device based on the liquid level of the containing chamber being greater than or equal to a preset height.

[0040] In this technical solution, before starting the ultrasonic treatment, the liquid level in the accommodating cavity is first detected by the liquid level sensor, and the ultrasonic generator is started only when the obtained liquid level reaches a preset height. This prevents the ultrasonic wave emitted by the ultrasonic generator from damaging other components in the food processor due to the user forgetting to place food, placing too little food, or misoperation, which is beneficial to improving the safety of the food processor, and can also prevent the food processor from working in vain, saving resource consumption.

[0041] Furthermore, when the liquid level is lower than a preset height, a warning message is output to remind the user that there is insufficient food in the receiving cavity, thereby improving the working efficiency of the food processor.

[0042] In any of the above technical solutions, further, the preset pressure difference is greater than 5 kPa.

[0043] In this technical solution, the preset pressure difference is greater than 5 kPa, that is, the pressure change amount in the accommodation cavity is greater than 5 kPa. The preset pressure difference is used to apply a changing pressure to the food in the accommodation cavity, and the relatively large preset pressure difference can ensure the speed of liquid entering the internal voids of the food material. It can not only accelerate the precipitation of flavor components of the food material, but also facilitate the better transmission of ultrasonic waves inside the food material, enhance the dissolution of nutrient components of the food material, and greatly shorten the required time on the basis of ensuring the food processing effect.

[0044] In addition, considering the safety of the food processor, the preset pressure difference should not be too large, so as to prevent the pressure in the accommodation cavity from exceeding the pressure that the food processor can withstand after adjusting the pressure in the accommodation cavity according to the preset pressure difference.

[0045] According to the second aspect of the present invention, a control device is also proposed, which includes a processor, a memory, and a program or instruction stored on the memory and executable on the processor. When the program or instruction is executed by the processor, the steps of the control method of the food processor proposed in the first aspect are realized. Therefore, this control device has all the beneficial effects of the control method of the food processor proposed in the first aspect. To avoid repetition, it will not be elaborated too much here.

[0046] According to the third aspect of the present invention, a food processor is also proposed, which includes: a housing; a container detachably connected to the housing, and the container includes: a body provided with an accommodation cavity; an ultrasonic generating device disposed on the body, and at least part of the ultrasonic generating device extends into the accommodation cavity from the bottom of the container; a pressure device disposed in the housing, and the pressure device is used to adjust the pressure in the accommodation cavity; the control device proposed in the second aspect, which is connected to the ultrasonic generating device and the pressure device.

[0047] In this technical solution, the food processor includes: a housing, a container, and a pressure device. Among them, the container is carried on the housing, and the container includes a body and an ultrasonic generating device.

[0048] Specifically, the body is provided with an accommodation cavity, and the food material and liquid to be processed can be accommodated in the accommodation cavity. The ultrasonic generating device is disposed on the body, and at least a part of the ultrasonic generating device extends into the accommodation cavity. The ultrasonic waves generated by the ultrasonic generating device can form a disturbance to the liquid and the food material to be processed, and the liquid and the food material to be processed change from a static state to a flowing state, which can increase the dissolution speed of water-soluble substances in the food material to be processed, shorten the processing time, and reduce the waiting time of the user. The pressure device is disposed in the housing and communicated with the accommodation cavity, and the pressure change in the accommodation cavity is realized through the pressure device, so as to accelerate the entry of liquid or ultrasonic waves into the internal voids of the food material and accelerate the dissolution of nutrient components of the food material. The control device is electrically connected to the ultrasonic generating device and the pressure device, and this control device is used to respond to the start instruction of the food processor, control the pressure device to form a preset pressure difference in the accommodation cavity, and control the operation of the ultrasonic generating device according to the preset ultrasonic parameters.

[0049] In this technical solution, the pressure device of the food processor is controlled to operate to change the pressure in the accommodation cavity to form a preset pressure difference, and the ultrasonic generating device of the food processor is controlled to operate according to preset ultrasonic parameters to generate ultrasonic waves to disturb the food in the accommodation cavity. On the one hand, by using the pressure difference after the pressure change, a changing pressure is applied to the food in the accommodation cavity, thereby opening the internal channels of the to-be-processed food materials and accelerating the entry of liquid into the internal voids of the food materials. This can not only accelerate the extraction of flavor components from the food materials, but also facilitate the better transmission of ultrasonic waves inside the food materials, enhancing the dissolution of nutrient components in the food materials, and greatly shortening the required time while ensuring the food processing effect. On the other hand, by using the strong cavitation effect, mechanical vibration, disturbance effect, high acceleration, emulsification, diffusion, crushing and stirring effects, etc. generated by the ultrasonic radiation pressure of the ultrasonic generating device, the molecular motion frequency and speed of substances and the liquid penetration power are increased, thereby accelerating the entry of nutrient components of the food materials into the water, promoting the leaching of flavor substances, making the aroma and sweetness of the drink more prominent, reducing the bitter and astringent flavor, effectively improving the food processing speed, shortening the waiting time of the user, and quickly forming the required food even at normal temperature or low temperature.

[0050] In any of the above technical solutions, further, the food processor further includes: a heat exchange device, which is arranged on the housing and electrically connected to the control device, and the heat exchange device can perform heat exchange with the container, wherein the heat exchange device includes a refrigeration device and / or a heating device.

[0051] In this technical solution, the refrigeration / heating function of the food in the accommodation cavity is realized through the heat exchange device. Specifically, the surface temperature of the container is reduced by the refrigeration device, and the container exchanges heat with the food in the accommodation cavity to prevent the temperature of the food from rising, ensuring the ultrasonic processing effect of the food, and preventing the influence of the food temperature rise on the taste when the ultrasonic generating device works.

[0052] Further, when the temperature in the accommodation cavity is lower than the second preset temperature, the food can be heated by the heating device so that the temperature of the food can quickly rise to the optimal temperature required for food processing. Thereby making the aroma and sweetness of the drink more prominent, reducing the bitter and astringent flavor, effectively enhancing the extraction effect, and improving the quality of the finished product.

[0053] In any of the above technical solutions, further, the pressure device includes at least one of the following: an air extraction component, an air inflation component, and a pressure control valve.

[0054] In this technical solution, the gas in the accommodation cavity is extracted by the air extraction component to reduce the pressure in the accommodation cavity. The air inflation component is used to supplement gas to the accommodation cavity to increase the pressure in the accommodation cavity. The pressure control valve connects the accommodation cavity and the external space of the food processor, so that the pressure in the accommodation cavity can quickly return to normal pressure.

[0055] In any of the above technical solutions, further, the container is detachably connected to the housing.

[0056] In this technical solution, the container is detachably connected to the housing. After the food in the container is processed, the container can be taken out of the housing, which is convenient for cleaning and maintaining the container.

[0057] According to the fourth aspect of the present invention, a readable storage medium is provided, on which a program or instruction is stored. When the program or instruction is executed by a processor, it executes the control method of the food processor proposed in the first aspect. Therefore, this readable storage medium has all the beneficial effects of the control method of the food processor proposed in the first aspect. To avoid repetition, no further elaboration will be provided.

[0072] In order to be able to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0073] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0074] Next, refer to Figures 1 to 10 Describe a control method, a control device, a food processor and a readable storage medium of a food processor according to some embodiments of the present invention.

[0075] Embodiment 1:

[0076] As Figure 1 shown, according to an embodiment of the first aspect of the present invention, a control method of a food processor is proposed, wherein the food processor includes a receiving cavity, an ultrasonic generating device and a pressure device, the ultrasonic generating device is used to agitate the food in the receiving cavity, and the pressure device is used to adjust the pressure in the receiving cavity; the method includes:

[0077] Step 102, in response to a start instruction of the food processor, control the pressure device to form a preset pressure difference in the receiving cavity, and control the ultrasonic generating device to operate according to preset ultrasonic parameters.

[0078] In this embodiment, when the user needs to process food, such as making cold brew drinks, the user can first add the ingredients and liquid to be processed into the accommodating cavity of the food processor, and then issue a start instruction for the food processor by operating the food processor. The food processor responds to the instruction to process the ingredients to be processed, that is, the start instruction, and starts to process the ingredients. Among them, the food in the accommodating cavity includes the ingredients to be processed and the liquid for soaking the ingredients. The ingredients to be processed include coffee, flowers, fruits, tea, traditional Chinese medicine, wine, etc.

[0079] Further, after the food processor is started, control the pressure device of the food processor to operate to change the pressure in the accommodating cavity to form a preset pressure difference, and control the ultrasonic generating device of the food processor to operate according to the preset ultrasonic parameters to generate ultrasonic waves to disturb the food in the accommodating cavity. On the one hand, utilize the pressure difference after the pressure change to apply a changing pressure to the food in the accommodating cavity, thereby opening the internal channels of the ingredients to be processed and accelerating the liquid to enter the internal voids of the ingredients. This can not only accelerate the precipitation of flavor components in the ingredients, but also facilitate the better transmission of ultrasonic waves inside the ingredients, enhance the dissolution of nutritional components in the ingredients, and greatly shorten the required time while ensuring the food processing effect. On the other hand, utilize the strong cavitation effect, mechanical vibration, disturbance effect, high acceleration, emulsification, diffusion, crushing and stirring effects, etc. generated by the ultrasonic radiation pressure of the ultrasonic generating device to increase the molecular motion frequency and speed of substances and the liquid penetration ability, thereby accelerating the entry of nutritional components of the ingredients into the water, promoting the leaching of flavor substances, making the aroma and sweetness of the drink more prominent, reducing the bitter and astringent flavor, effectively improving the food processing speed, shortening the waiting time of the user, and quickly forming the required finished product even at normal temperature or low temperature.

[0080] It can be understood that when receiving the start instruction, the pressure device and the ultrasonic generating device can start working simultaneously to further shorten the time required for processing food, or they can start working successively to avoid mutual influence between the pressure device and the ultrasonic generating device.

[0081] It should be noted that the food processor includes a housing, a main body, an ultrasonic generating device, and a pressure device. The main body is provided with a receiving cavity, and the food ingredients and liquid to be processed can be accommodated in the receiving cavity. The ultrasonic generating device is disposed on the main body, and at least a part of the ultrasonic generating device extends into the receiving cavity. The ultrasonic waves generated by the ultrasonic generating device can form a disturbance to the liquid and the object to be processed, changing the liquid and the food ingredients to be processed from a static state to a flowing state, which can accelerate the dissolution rate of water-soluble substances in the food to be processed, speed up the food processing speed, shorten the processing time, reduce the waiting time of the user, enable the user to eat the processed food as soon as possible, and is conducive to enhancing the competitiveness of the product and improving the user experience of using the food processor. The pressure device is disposed in the housing and communicates with the receiving cavity, and the pressure change in the receiving cavity is realized through the pressure device, so as to accelerate the entry of the liquid or ultrasonic waves into the internal voids of the food ingredients and accelerate the dissolution of the nutritional components of the food ingredients.

[0082] Specifically, the food processor includes a cold brew machine. The pressure device includes an air extraction assembly, a pressure control valve, an air inflation assembly, etc.

[0083] Furthermore, the preset pressure difference is greater than 5 kPa. That is, the pressure change amount in the receiving cavity is greater than 5 kPa. The changing pressure is applied to the food in the receiving cavity by using the preset pressure difference, and the larger preset pressure difference can ensure the speed of the liquid entering the internal voids of the food ingredients. It can not only accelerate the precipitation of the flavor components of the food ingredients, but also facilitate the better transmission of ultrasonic waves inside the food ingredients, enhance the dissolution of the nutritional components of the food ingredients, and greatly shorten the required time on the basis of ensuring the food processing effect. For example, the preset pressure difference is 10 kPa, 15 kPa, 25 kPa, etc. In addition, the preset pressure difference is also related to the pressure that the food processor can withstand. Considering the safety of the food processor, the preset pressure difference should not be too large, so as to prevent the pressure in the receiving cavity from exceeding the pressure that the food processor can withstand after adjusting the pressure in the receiving cavity according to the preset pressure difference. If the pressure in the receiving cavity adjusted according to the preset pressure difference exceeds the pressure that the food processor can withstand, the pressure is adjusted to the pressure that the food processor can withstand. For example, the preset pressure difference is 30 kPa, the initial pressure in the receiving cavity is 15 kPa, and after increasing the pressure according to the preset pressure difference, the pressure in the receiving cavity will become 45 kPa, exceeding the pressure that the food processor can withstand (40 kPa). At this time, the pressure can only be increased to 40 kPa.

[0084] Embodiment 2:

[0085] As Figure 2 shown, according to an embodiment of the present invention, a control method for a food processor is proposed, including:

[0086] Step 202, in response to the start instruction of the food processor, controlling the pressure device to work periodically according to the preset pressure difference;

[0087] Step 204, determine the first working duration during the periodic operation of the pressure device;

[0088] Step 206, check whether the first working duration is greater than or equal to the second preset duration. If so, proceed to step 208; if not, proceed to step 204;

[0089] Step 208, control the ultrasonic generating device to operate according to the preset ultrasonic parameters;

[0090] Step 210, check whether the first working duration is greater than or equal to the first preset duration. If so, proceed to step 212; if not, proceed to step 204;

[0091] Step 212, turn off the pressure device.

[0092] In this embodiment, the pressure device is controlled to operate periodically at preset time intervals, so that the pressure in the accommodation cavity first increases and then decreases or first decreases and then increases. Thus, by applying alternating pressure to the food in the accommodation cavity first, the internal channels of the to-be-processed food materials are opened up, which can not only accelerate the precipitation of the flavor components of the food materials, but also enable the subsequent ultrasonic waves to be better transmitted inside the food materials, taking into account both the ultrasonic treatment effect and speed, and greatly shortening the waiting time of the user.

[0093] Furthermore, during the operation of the pressure device, record the cumulative first working duration during the periodic operation of the pressure device. When the first working duration is greater than or equal to the first preset duration, it indicates that the pressure change control process of the pressure device is completed, and then control the pressure device to stop working.

[0094] Among them, considering that the pressure device operates at a specified time interval, in the case of no timing device, the first working duration during the periodic operation of the pressure device can be determined by the number of starts of the pressure device, the number of cycles of periodic operation, or the pressure change frequency. It should be noted that within one working cycle, the pressure device will start twice. The first start is to increase or decrease the pressure in the accommodation cavity based on the initial pressure to form a preset pressure difference, and the second start is when the pressure in the accommodation cavity returns to the initial pressure. That is, the number of cycles = 2 × the number of starts.

[0095] Taking the example that the pressure in the accommodating cavity first rises and then falls, the periodic operation of the pressure control device specifically includes: inflating the accommodating cavity through the pressure control device to increase the pressure in the accommodating cavity to a first pressure threshold, where the first pressure threshold is the sum of the initial pressure of the accommodating cavity (e.g., atmospheric pressure) and a preset pressure difference. When the pressure holding duration at the first pressure threshold in the accommodating cavity is greater than or equal to a first duration threshold, the pressure control device is controlled again to restore (decrease) the pressure in the accommodating cavity to the initial pressure. At this time, the number of operating cycles of the pressure control device is incremented by 1, or the number of startup times is incremented by 2 times. Here, the first duration threshold is the pressure holding time during the pressure change process in the accommodating cavity and can be reasonably set according to requirements. Of course, the first duration threshold can also be 0, that is, the pressure decreases immediately after it rises. When the duration after the pressure in the accommodating cavity is restored to the initial pressure is greater than or equal to a preset time interval, the above pressure control steps are repeated until the first operating duration in the periodic operation of the pressure control device is greater than or equal to a first preset duration. After confirming that the pressure control is completed, the pressure control device is turned off. Taking the example that the pressure in the accommodating cavity first falls and then rises, the periodic operation of the pressure control device specifically includes: extracting the gas in the accommodating cavity through the pressure control device to reduce the pressure in the accommodating cavity to a second pressure threshold, where the second pressure threshold is the difference between the initial pressure of the accommodating cavity (e.g., atmospheric pressure) and a preset pressure difference. When the pressure holding duration at the second pressure threshold in the accommodating cavity is greater than or equal to the first duration threshold, the pressure control device is controlled again to inflate the accommodating cavity to restore (increase) the pressure in the accommodating cavity to the initial pressure. At this time, the number of operating cycles is incremented by 1, or the number of startup times is incremented by 2 times. When the duration after the pressure in the accommodating cavity is restored to the initial pressure is greater than or equal to a preset time interval, the above pressure control steps are repeated until the first operating duration in the periodic operation of the pressure control device is greater than or equal to a first preset duration. After confirming that the pressure control is completed, the pressure control device is turned off.

[0096] It can be understood that the increase in the pressure in the accommodating cavity can be achieved through an inflating device or a pressure control valve, and the decrease in the pressure in the accommodating cavity can be achieved through an air extraction device or a pressure control valve. The pressure control method for each operation of the pressure control device can be the same or different. For example, during the first pressure control, the pressure in the accommodating cavity first rises and then falls, and during the second pressure control, the pressure in the accommodating cavity first falls and then rises. Or during both the first and second pressure controls, the pressure control device is used to make the pressure in the accommodating cavity first rise and then fall.

[0097] Among them, the first preset duration is the time required for the pressure control steps and can be reasonably set according to the type and weight of the food. The second preset duration is less than or equal to the first preset duration. If the second preset duration is less than the first preset duration and greater than 0, the ultrasonic generating device is started during the pressure control operation of the pressure control device. If the second preset duration is equal to the first preset duration, the ultrasonic generating device is started after the pressure control of the pressure control device is completed, that is, after the pressure control device is turned off. If the second preset duration is equal to 0, that is, the pressure control device and the ultrasonic generating device are started simultaneously.

[0098] Embodiment 3:

[0099] As Figure 3 shown, according to an embodiment of the present invention, a control method for a food processor is provided, including:

[0100] Step 302, in response to a start instruction of the food processor, control the ultrasonic generating device to continuously operate according to the operating parameters in the preset ultrasonic parameters;

[0101] Step 304, determine the second working duration during the operation of the ultrasonic generating device;

[0102] Step 306, determine whether the second working duration is greater than or equal to a fourth preset duration. If so, proceed to step 308; if not, proceed to step 304;

[0103] Step 308, control the pressure device to form a preset pressure difference in the accommodating cavity;

[0104] Step 310, determine whether the second working duration is greater than or equal to a third preset duration. If so, proceed to step 312; if not, proceed to step 304;

[0105] Step 312, turn off the ultrasonic generating device.

[0106] In this embodiment, when the ultrasonic generating device and the pressure device are started successively, in response to the start instruction, the ultrasonic generating device is first started according to the operating parameters (such as ultrasonic power, frequency, etc.) in the preset ultrasonic parameters. The ultrasonic waves emitted by the ultrasonic generating device disturb the food ingredients to be processed in the accommodating cavity, so that the ingredients in the food will obtain kinetic energy and move, thereby promoting the leaching of flavor substances and accelerating the rapid dissolution of water-soluble substances into the liquid. And the second working duration of the ultrasonic generating device is started simultaneously when the ultrasonic generating device is started. When the second working duration is greater than or equal to the third preset duration in the preset ultrasonic parameters, it indicates that the ultrasonic treatment of the food is completed. At this time, the ultrasonic generating device is controlled to be turned off. Thus, the automatic ultrasonic treatment of the food is realized, which can effectively improve the treatment speed, shorten the waiting time of the user, and quickly form the required food even at normal temperature or low temperature. Moreover, by reasonably setting the ultrasonic parameters, the dissolution of bad flavor components is reduced, making the aroma and sweetness of the drink more prominent and reducing the bitter flavor.

[0107] Furthermore, considering the penetrability of ultrasonic waves, ultrasonic waves can not only disturb food but also affect other components in the food processor. To reduce the impact of ultrasonic waves on the food processor, when the second working duration of the ultrasonic wave generating device reaches (is greater than or equal to) the fourth preset duration, the pressure device is then controlled to apply alternating pressure to the food in the accommodating cavity, that is, the pressure control step is performed during or after the ultrasonic treatment process. Thus, first, the ultrasonic waves are used to increase the molecular movement frequency, speed, and liquid penetration power of substances, accelerating the entry of food nutrient components into water, and then alternating pressure is applied to the food in the accommodating cavity to open the internal channels of the to-be-processed food, accelerating the entry of liquid into the internal voids of the food, and accelerating the precipitation of food flavor components. On the one hand, it avoids severely damaging the food structure when the ultrasonic wave generating device and the pressure device work simultaneously, which affects the taste of the processed food. On the other hand, by adjusting the pressure instead of ultrasonic treatment, on the basis of accelerating the dissolution rate of water-soluble substances in the to-be-processed food, the time required for ultrasonic treatment is reduced, and further damage to food crushing and the food processor caused by ultrasonic waves is minimized.

[0108] It can be understood that the working mode of the ultrasonic wave generating device can be to continuously work at a specified ultrasonic power and frequency, which is beneficial to accelerating the precipitation of flavor substances in the food and greatly shortening the processing time required.

[0109] Among them, the preset ultrasonic parameters include the operating parameters of the ultrasonic treatment device and the third preset duration. The third preset duration is the time required for the ultrasonic step and can be reasonably set according to the type and weight of the food. The operating parameters include at least one of the following: ultrasonic frequency, ultrasonic power, preset on-off ratio, and the operating parameters are related to the model of the ultrasonic treatment device. The fourth preset duration is less than or equal to the third preset duration and can be reasonably set according to user needs. If the fourth preset duration is less than the third preset duration and greater than 0, the pressure device is started during the operation of the ultrasonic wave generating device. If the fourth preset duration is equal to the third preset duration, the pressure device is started after the ultrasonic treatment of the food by the ultrasonic wave generating device is completed, that is, after the ultrasonic wave generating device is turned off, to adjust the pressure. If the fourth preset duration is equal to 0, that is, the pressure device and the ultrasonic wave generating device are started simultaneously.

[0110] It should be noted that due to the differences in the types of to-be-cooked food and liquid, the parameters required for ultrasonic treatment are also different. Therefore, the type of food in the accommodating cavity can be obtained first, and according to the corresponding relationship between the preset food types and the preset ultrasonic parameters of the ultrasonic wave generating device, the preset ultrasonic parameters required for this type of food are searched, so as to accurately control the mechanical energy obtained by the food, further shorten the time required for ultrasonic treatment, and avoid problems such as severe crushing of the food caused by excessive ultrasonic treatment, improving the user experience.

[0111] Example 4:

[0112] As Figure 4 shown, according to an embodiment of the present invention, a control method for a food processor is provided. The food processor includes a refrigeration device for cooling food. The control method includes:

[0113] Step 402, in response to a start instruction of the food processor, controlling a pressure device to form a preset pressure difference in the accommodation cavity and controlling an ultrasonic generating device to operate according to preset ultrasonic parameters;

[0114] Step 404, determining whether the temperature in the accommodation cavity is greater than a first preset temperature. If so, proceed to step 406; if not, proceed to step 402;

[0115] Step 406, controlling the refrigeration device to operate according to preset refrigeration parameters.

[0116] In this embodiment, considering that during the food processing process, there are situations where the initial temperature of the liquid added to the food processor is higher than the temperature required by the user, or the liquid temperature rises due to the operation of the ultrasonic generating device. Therefore, during the food processing process, if it is detected that the temperature in the accommodation cavity is greater than the first preset temperature, it indicates that the current food temperature is higher than the temperature required by the user. Then, control the refrigeration device of the food processor to cool the food until the temperature in the accommodation cavity drops to the first preset temperature, and then control the refrigeration device to stop cooling. This enables the food to quickly reach the temperature required by the user, thereby taking into account both the food processing efficiency and the taste of the processed food, and can also avoid the problem of food temperature rise caused by the operation of the ultrasonic generating device. The desired food can be quickly formed at room temperature, meeting various needs of users for food processing. Among them, the temperature in the accommodation cavity can be approximately regarded as the food temperature.

[0117] It is worth mentioning that the refrigeration device can be started synchronously with the pressure device and the ultrasonic generating device, which is beneficial to reducing the food processing time and enabling the user to obtain the required finished product faster.

[0118] Furthermore, if it is detected that the temperature in the accommodation cavity is less than or equal to the first preset temperature, it indicates that the food temperature already meets the user's requirements at this time, and there is no need to start the refrigeration device.

[0119] Specifically, the preset refrigeration parameter can be determined according to the ambient temperature of the space where the food processor is located, as well as the difference between the temperature in the accommodating cavity and the first preset temperature. Thus, while ensuring the cooling effect of the refrigeration device, the preset refrigeration parameter is dynamically set to reduce the energy consumption of the food processor. For example, the ambient temperature is 25°C, the temperature of the food is 15°C, and the first preset temperature is 3°C. The gap between the ambient temperature and the difference between the temperature of the food and the first preset temperature is relatively large. The relatively high ambient temperature will inhibit the decrease of the food temperature. Then, according to the corresponding relationship between the preset ambient temperature and the compensation amount, the temperature compensation amount corresponding to the ambient temperature is determined, and the required preset refrigeration parameter is queried according to the difference and the temperature compensation amount.

[0120] Among them, the preset refrigeration parameter includes the refrigeration power and the refrigeration duration. When the refrigeration power of the refrigeration device is not adjustable, the required refrigeration duration of the refrigeration device can be determined according to the ambient temperature and the difference, so as to determine whether the temperature of the food has dropped to the first preset temperature through the refrigeration time. When the refrigeration time is not adjustable, the required refrigeration power of the refrigeration device can be determined according to the ambient temperature and the difference, and the temperature of the food can be made to drop to the first preset temperature within the refrigeration time by controlling the refrigeration power.

[0121] It can be understood that among them, the first preset temperature is the required temperature of the finished product after the user processes the food and can be set as needed. The first preset temperature can be 10°C or 2°C, etc. Further, the food processor can pre-configure a response function of the first preset temperature in the control device, and this response function indicates the corresponding relationship between the first preset temperature and the user's identity information, and / or the corresponding relationship between the first preset temperature and the weather information of the region where the food processor is located. For a food processor with the function of determining the user's identity information and weather information, after obtaining the user's identity information and / or identity information, the corresponding first preset temperature can be directly queried automatically according to the identity information and / or weather information. For example, when the weather temperature is relatively high, a relatively low value is selected for the first preset temperature. Thus, it is avoided that the user repeatedly sets the first preset temperature, improving the convenience of the food processor and meeting the user's usage experience.

[0122] Embodiment 5:

[0123] As Figure 5 shown, according to an embodiment of the present invention, a control method for a food processor is proposed, including:

[0124] Step 502, in response to the start instruction of the food processor, control the pressure device to form a preset pressure difference in the accommodating cavity, and control the ultrasonic generating device to work intermittently according to the operating parameters in the preset ultrasonic parameters;

[0125] Step 504: Whether the second working duration of the ultrasonic generating device is greater than or equal to the fifth preset duration. If yes, go to step 506; if no, go to step 502;

[0126] Step 506: Control the refrigeration device to work according to the preset refrigeration parameters;

[0127] Step 508: Whether the second working duration of the ultrasonic generating device is greater than or equal to the third preset duration. If yes, go to step 510; if no, go to step 502;

[0128] Step 510: Turn off the ultrasonic generating device;

[0129] Step 512: Whether the first working duration of the pressure device is greater than or equal to the first preset duration. If yes, go to step 514; if no, go to step 502;

[0130] Step 514: Turn off the pressure device.

[0131] In this embodiment, considering that a relatively low temperature is not conducive to the dissolution of nutrients. Therefore, the ultrasonic generating device is started first to perform ultrasonic treatment on the food to be processed under the temperature condition that does not affect the dissolution of nutrients. After the second working duration of the ultrasonic generating device is greater than or equal to the fifth preset duration, the refrigeration device is then turned on. This can not only ensure that the temperature does not drop during the ultrasonic treatment process and the ultrasonic treatment effect is better, but also prevent the influence of food temperature rise on the food taste when the ultrasonic generating device is working through subsequent cooling treatment.

[0132] Among them, the fifth preset duration is less than or equal to the third preset duration in the preset ultrasonic parameters, that is, the refrigeration device can be turned on during or after the ultrasonic treatment process.

[0133] Specifically, the working mode of the ultrasonic generating device can be intermittent working according to the ultrasonic power and the preset on-off ratio, so as to avoid faults such as overheating and damage of the ultrasonic generating device on the basis of ensuring the ultrasonic treatment effect, and effectively extend the service life of the food processor.

[0134] Furthermore, when it is detected that the temperature in the accommodation cavity is less than or equal to the first preset temperature, the second working duration of the ultrasonic generating device is greater than or equal to the third preset duration, and the first working duration of the periodic working of the pressure device is greater than or equal to the first preset duration, it indicates that the food processing is completed. At this time, a prompt message is output to remind the user to pick up the food in time. Among them, the prompt message can be text, image, audio, light, etc. For example, the buzzer is set to sound intermittently several times. Among them, the prompt message can be text, image, audio, light, etc. For example, the buzzer is set to sound intermittently several times.

[0135] Embodiment 6:

[0136] like Figure 6 As shown, according to one embodiment of the present invention, a control method for a food processor is provided, comprising:

[0137] Step 602, in response to a start instruction of the food processor, obtaining the temperature in the receiving chamber;

[0138] Step 604, whether the temperature in the receiving chamber is less than the second preset temperature, if so, proceed to step 606, if not, proceed to step 612;

[0139] Step 606, controlling the heating device to operate according to preset heating parameters;

[0140] Step 608, whether the temperature in the receiving chamber rises to the second preset temperature, if so, proceed to step 610, if not, proceed to step 606;

[0141] Step 610, turning off the heating device;

[0142] Step 612, controlling the pressure device to form a preset pressure difference in the containing chamber, and controlling the operation of the ultrasonic generating device according to preset ultrasonic parameters.

[0143] In this embodiment, a heating device is also provided in the food processor, and the food in the receiving chamber can be heated by the heating device. Specifically, since too low a temperature is not conducive to the extraction of flavor substances, it seriously affects the food processing efficiency. Therefore, when the temperature of the food is lower than the second preset temperature, the food can be heated by the heating device until the temperature in the receiving chamber is equal to the second preset temperature, and then the heating device is controlled to be turned off, so that the temperature of the food can be quickly raised to the optimal temperature for food processing (the second preset temperature). Thereby, the aroma and sweetness of the drink are more prominent, the bitter flavor is reduced, the food processing effect is effectively enhanced, and the quality of the finished product is improved, and it is also conducive to improving the food processing efficiency.

[0144] Among them, the second preset temperature is the optimal processing temperature for food ingredients, and the second preset temperature can be set according to the type of food. For example, if the first preset temperature set by the user is 5°C, room temperature water or hot water can be added to extract tea leaves. Compared with directly using ice water for extraction, higher temperature water has better extraction efficiency and extraction effect, which is conducive to improving the precipitation of tea polyphenols and other substances, thereby improving the quality of tea water. After extraction, the tea water can be cooled down to 5°C.

[0145] In addition, when users need hot food, they can first use a liquid with a lower temperature for ultrasonic processing, and then heat it up through a heating device, so as to meet different temperature requirements for the finished product, improve the reliability of the food processor, and help improve the competitiveness of the product and enhance the user experience of the food processor.

[0146] Embodiment 7:

[0147] As Figure 7 shown, according to an embodiment of the present invention, a control method for a food processor is provided, including:

[0148] Step 702, in response to a start instruction of the food processor, control the pressure device to form a preset pressure difference in the accommodation cavity, and obtain the liquid level height of the accommodation cavity;

[0149] Step 704, determine whether the liquid level height is greater than or equal to a preset height. If so, proceed to step 706; if not, proceed to step 708;

[0150] Step 706, control the ultrasonic generating device to operate according to preset ultrasonic parameters;

[0151] Step 708, output a warning message.

[0152] In this embodiment, before starting the ultrasonic treatment, the liquid level height in the accommodation cavity is first detected by a liquid level sensor, and the ultrasonic generating device will be started only when the obtained liquid level height reaches the preset height. This can avoid damage to other components in the food processor caused by the ultrasonic waves emitted by the ultrasonic generating device due to the user forgetting to place food, placing too little food, or misoperation, which is beneficial to improving the safety of the food processor, and can also avoid the unnecessary operation of the food processor and save resource consumption.

[0153] Further, when the liquid level height is less than the preset height, a warning message is output to prompt the user that the food in the accommodation cavity is insufficient, thereby improving the working efficiency of the food processor.

[0154] Embodiment 8:

[0155] According to a specific embodiment of the present invention, an extraction method for a beverage is provided, with the specific cooking process: put ingredients and water → ultrasonic → pressure control (+ refrigeration) → cooking end.

[0156] 1. Put ingredients and water in a container and start the cooking program.

The operating parameters are: ultrasonic frequency 20 kHz - 80 kHz, ultrasonic power 30 W - 400 W, and the working time (the third preset duration) is 2 min - 40 min. The ultrasonic generating device can work continuously or intermittently.

[0158] 3. Pressure control: The pressure device is started;

[0159] (1) First, evacuate the inside of the container to form a vacuum, and at this time, the pressure inside the container is p1;

[0160] (2) Vent the container, or directly inflate and pressurize it to form normal pressure or positive pressure inside. At this time, the pressure inside the container is p2, where the pressure difference |p1 - p2| ≥ 10 kPa;

[0162] 4. Refrigeration (applicable to low-temperature extraction): Start the refrigeration device to cool the ingredients and water inside the container. The optimal temperature range for maintaining cooling is 4°C - 15°C.

[0163] 5. The total cooking time ≥ 5 min, and the cooking ends.

[0164] Among them, the ultrasonic and pressure control steps can work simultaneously during cooking or in a sequential order, as long as the working time of ultrasonic, the pressure difference of pressure control, and the number of cycles are ensured.

[0165] Specifically, taking tea extraction as an example, the cooking process is as follows:

[0166] 1. Put 3 g of tea and 450 g of water into the container and start the cooking program.

[0167] 2. Ultrasonic: Start the ultrasonic wave generating device to make the ultrasonic oscillator start working. Operating parameters: ultrasonic frequency 46 kHz, ultrasonic power 60 W, continuous working time is 5 min.

[0168] 3. Pressure control: Start the pressure device;

[0170] (2) Vent the container to make the internal pressure p2 reach normal pressure 0 kPa and last for 30 s;

[0171] (3) Repeat 3 times, and the total pressure control time is 5 min.

[0172] 4. Refrigeration (applicable to low-temperature extraction): Start the refrigeration device to cool the ingredients and water in the container and work continuously for 5 min.

[0173] 5. Ultrasonic, pressure control, and refrigeration are turned on and off simultaneously, and the total cooking time is 5 min.

[0174] Taking coffee extraction as an example, the cooking process is as follows:

[0175] 1. Put 20 g of coffee and 300 g of water into the cup and start the cooking program.

[0176] 2. Ultrasonic: Start the ultrasonic wave generating device to make the ultrasonic oscillator start working. Operating parameters: ultrasonic frequency 30 kHz, ultrasonic power 100 W, continuous working time is 5 min.

[0182] 5. Turn on the ultrasonic, pressure control, and refrigeration simultaneously and end simultaneously. The total cooking time is 5 min.

[0183] In this embodiment, the ultrasonic and pressure control devices are combined. By using the strong cavitation effect, mechanical vibration, disturbance effect, high acceleration, emulsification, diffusion, crushing, and stirring effects generated by the ultrasonic radiation pressure, the movement frequency and speed of matter molecules are increased, the water penetration ability is enhanced, and thus the acceleration of the entry of food material nutrients into the water is achieved. And through alternating pressure control, alternating pressure is applied to the food materials to open the internal channels of the food materials, accelerate the entry of water into the internal voids of the food materials, which is beneficial to the better transmission of ultrasonic waves inside the food materials, accelerate the dissolution of food material nutrients, accelerate the extraction of tea and coffee, and shorten the extraction time.

[0184] Among them, the food processor consists of a container, a pressure device, an ultrasonic generating device (ultrasonic vibrator, ultrasonic module), and a base. The refrigeration device can refrigerate the drink in the container. The ultrasonic module controls the operation of the ultrasonic vibrator. The ultrasonic vibrator can be inserted into the container to contact the food materials, or can be at the bottom of the container to transmit vibrations to the food materials by driving the container to vibrate.

[0186] As Figure 8 shown, according to an embodiment of the second aspect of the present invention, a control device 800 is proposed, which includes a processor 804, a memory 802, and a program or instruction stored on the memory 802 and executable on the processor 804. When the program or instruction is executed by the processor 804, it realizes the steps of the control method of the food processor proposed in the embodiment of the first aspect. Therefore, the control device 800 has all the beneficial effects of the control method of the food processor proposed in the embodiment of the first aspect.

[0187] Embodiment 10:

[0188] As Figure 9and Figure 10 As shown in Figure 10 , according to an embodiment of the third aspect of the present invention, a food processor 900 is provided, which includes: a housing 920, a container 910, a pressure device (not shown in the figure), and a control device 800 proposed in the embodiment of the second aspect.

[0189] Specifically, the container 910 is carried on the housing 920. The container 910 includes a main body 912 and an ultrasonic generating device 914. The main body 912 is provided with a receiving cavity, and the ingredients and liquid to be processed can be received in the receiving cavity. The ultrasonic generating device 914 is disposed on the main body 912, and at least a part of the ultrasonic generating device 914 extends into the receiving cavity. The housing 920 can accommodate the container 910 and the pressure device. The control device 800 is connected to the ultrasonic generating device 914 and the pressure device. The control device 800 is configured to control the pressure device to form a preset pressure difference in the receiving cavity in response to a start instruction of the food processor 900, and control the ultrasonic generating device 914 to operate according to preset ultrasonic parameters.

[0190] In this embodiment, the ultrasonic waves generated by the ultrasonic generating device 914 can form a disturbance to the liquid and the ingredients to be processed, changing the liquid and the ingredients to be processed from a static state to a flowing state, which can accelerate the dissolution rate of water-soluble substances in the ingredients to be processed, speed up the processing speed of the ingredients to be processed, shorten the processing time, and reduce the waiting time of the user. The pressure change in the receiving cavity is realized through the pressure device, so as to accelerate the entry of the liquid or ultrasonic waves into the internal voids of the ingredients and accelerate the dissolution of the nutrient components of the ingredients. Furthermore, by combining ultrasonic and pressure control operations, the required time is greatly shortened on the basis of ensuring the food processing effect, and the waiting time of the user is shortened.

[0191] Specifically, the ultrasonic generating device 914 is detachably connected to the main body 912, which is convenient for cleaning the container 910 and maintaining the ultrasonic generating device 914.

[0192] It can be understood that after the ingredients to be extracted in the container 910 are extracted, the container 910 can be taken out of the housing 920, and the user can carry the container 910 with him, which is convenient for the user to drink the extraction liquid at any time and improves the usability of the container 910 by the user. The container 910 further includes a lid, and the lid is screwed with the main body 912, which is convenient for the user to open and close the lid. The top of the main body 912 is hermetically screwed with the lid, so that the container 910 can be used as a portable cup.

[0193] In addition, the container 910 can be connected to the rear end of a water purifier to directly access clean water from the water purifier, saving the user the actions of fetching and pouring water.

[0194] Furthermore, the pressure device includes at least one of the following: an air extraction component, an air inflation component, and a pressure control valve. The air extraction component extracts the gas in the accommodation cavity to reduce the pressure in the accommodation cavity. The air inflation component replenishes the gas to the accommodation cavity to increase the pressure in the accommodation cavity. The pressure control valve connects the accommodation cavity and the external space of the food processor 900, so that the pressure in the accommodation cavity quickly returns to the initial pressure.

[0195] Specifically, taking the example that the pressure in the accommodation cavity first increases and then decreases, the specific control of the periodic operation of the pressure device includes: turning on the air inflation component to increase the pressure in the accommodation cavity to a first pressure threshold, where the first pressure threshold is the sum of the normal pressure (initial pressure) of the accommodation cavity and a preset pressure difference. When the pressure holding duration at the first pressure threshold in the accommodation cavity is greater than or equal to the first duration threshold, turn on the pressure control valve to exhaust air to restore (decrease) the pressure in the accommodation cavity to the initial pressure. Of course, the pressure in the accommodation cavity can also be reduced to less than the initial pressure through the air extraction component. At this time, the number of operating cycles of the pressure device is incremented by 1. When the duration after the pressure in the accommodation cavity returns to the initial pressure is greater than or equal to the preset time interval of the periodic operation, repeat the above pressure control steps until the first working duration in the periodic operation process of the pressure device is greater than or equal to the first preset duration, confirm that the pressure control is completed, and the pressure device can be turned off. Taking the example that the pressure in the accommodation cavity first decreases and then increases, the specific control of the periodic operation of the pressure device includes: turning on the air extraction component to reduce the pressure in the accommodation cavity to a second pressure threshold, where the second pressure threshold is the difference between the normal pressure (initial pressure) of the accommodation cavity and a preset pressure difference. At this time, the accommodation cavity is in a negative pressure state. When the pressure holding duration at the second pressure threshold in the accommodation cavity is greater than or equal to the first duration threshold, turn on the pressure control valve to inflate the air to restore (increase) the pressure in the accommodation cavity to the initial pressure. Of course, the pressure in the accommodation cavity can also be increased to greater than the initial pressure through the air inflation component. At this time, the number of operating cycles of the pressure device is incremented by 1. When the duration after the pressure in the accommodation cavity returns to the initial pressure is greater than or equal to the preset time interval, repeat the above pressure control steps until the first working duration in the periodic operation process of the pressure device is greater than or equal to the first preset duration, confirm that the pressure control is completed, and then turn off the pressure device.

[0196] Embodiment 11:

[0197] As Figure 10 shown, according to an embodiment of the present invention, it includes the features defined in any of the above embodiments, and further: the food processor 900 further includes: a heat exchange device 930, which is arranged in the housing 920 and is electrically connected to the control device 800. The heat exchange device 930 can perform heat exchange with the container 910, where the heat exchange device 930 includes a refrigeration device and / or a heating device.

[0198] In this embodiment, the refrigeration / heating function of the food in the accommodation cavity is realized through the heat exchange device 930. Specifically, the surface temperature of the container 910 is reduced by the refrigeration device, and the container 910 exchanges heat with the food in the accommodation cavity, preventing the food temperature from rising, ensuring the ultrasonic treatment effect of the food, and also preventing the influence of the food temperature rise on the taste when the ultrasonic generating device 914 is working. When the temperature in the accommodation cavity is lower than the second preset temperature, the food can be heated by the heating device, so that the temperature of the food can quickly rise to the optimal temperature for food processing. Thus, the aroma and sweetness of the beverage are more prominent, the bitter flavor is reduced, the processing effect is effectively enhanced, and the quality of the beverage is improved.

[0199] Specifically, the heat exchange device 930 realizes the refrigeration / heating function based on the Peltier effect. The heat exchange device 930 includes at least two base layers, at least two conduction layers, and thermoelectric semiconductors. At least two conduction layers are disposed on at least two base layers and are located between at least two relatively disposed base layers. The conduction layers are used for conducting electricity and heat. The conduction layers are connected to a power source, and the thermoelectric semiconductors are sandwiched between at least two conduction layers. When an electric current passes through the conduction layers and reaches the thermoelectric semiconductors, energy transfer will occur. Due to the different directions of the current input, heat absorption and heat release phenomena will occur at both ends of the thermoelectric semiconductors. The base layer facing the main body 912 is cooled to form a cold end, and the other base layer is heated to form a hot end, realizing the refrigeration function of the heat exchange device 930. In addition, the refrigeration can be controlled to the preset temperature required by continuously controlling the on / off of the current. If the user needs to heat the container 910, only the direction of the flowing current needs to be switched, so that the base layer facing the main body 912 is heated and the other side is cooled, thereby realizing the heating function of the heat exchange device 930 without adding new structures.

[0200] It is worth mentioning that a conduction member can also be provided between the heat exchange device 930 and the main body 912, thereby improving the heat transfer / cooling speed, increasing the heat exchange area at the same time, making the heat exchange of the container 910 more uniform, and greatly improving the heating / cooling efficiency. The food processor 900 further includes a temperature sensor for temperature detection to facilitate the precise control of the food processor 900 and improve the reliability of the food processor 900.

[0204] In this embodiment, the first coupler 942 is provided on the ultrasonic generating device 914, and the second coupler 944 is provided on the housing 920. After connecting the first coupler 942 on the ultrasonic generating device 914 to the second coupler 944 on the housing 920, power supply to the ultrasonic generating device 914 can be achieved, and the ultrasonic generating device 914 starts to operate.

[0208] In this embodiment, a waterproof component 950 is provided between the container 910 and the control device 800. The waterproof component 950 is connected to the housing 920, so that the waterproof component 950 and the housing 920 enclose a receiving space for the control device 800. The control device 800 is arranged in this receiving space, and the waterproof component 950 is used to shield the control device 800 to isolate the structure above the control device 800 that may leak water from the control device 800, thereby preventing the condensed water in the container 910 or the liquid accidentally poured by the user from penetrating into the control device 800, ensuring that the control device 800 is not soaked by the liquid, and greatly improving the operating safety of the food processor 900.
