[0041] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0042] In order to solve the above problems, the present invention provides a refrigerator 10. Figure 1 1 is a schematic diagram of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 may generally include a housing 100, and one or more storage compartments 110 are formed in the housing 100. The storage compartments 110 may be configured to form a refrigerated storage space, a frozen storage space, a variable temperature storage space, etc. according to the refrigeration temperature. Specifically, the number, function, and layout of the storage compartments 110 may be configured according to requirements.

[0043] The refrigerator 10 of the present invention may further include an ultrasonic auxiliary processing device 200 ( Figure 1 In this embodiment, the ultrasonic assisted processing device 200 is arranged in the cold storage space of the refrigerator 10. Of course, in some cases, the ultrasonic assisted processing device 200 can also be arranged in the frozen storage space or the variable temperature storage space. The functions of the ultrasonic assisted processing device 200 include but are not limited to assisting pickling and assisting freezing. The ultrasonic assisted processing device 200 can be mounted in the cold storage space in the form of a drawer or directly placed in the cold storage space.

[0044] The ultrasonic assisted processing device 200 includes at least a tray, an ultrasonic generator and an ultrasonic transducer, wherein the tray can be arranged in a refrigerated storage space for carrying the food to be processed. The ultrasonic transducer can be arranged at the bottom of the tray, and the ultrasonic generator can be arranged on the back side of the refrigerator 10, and is electrically connected to the ultrasonic transducer, and the ultrasonic transducer is vibrated by providing ultrasonic frequency electrical energy to the ultrasonic transducer, thereby realizing auxiliary pickling of the food. It should be noted that the working principle of the ultrasonic assisted processing device 200 is well known to those skilled in the art and will not be repeated here.

[0045] Figure 23 is a schematic block diagram of a refrigerator 10 according to an embodiment of the present invention. Further, the refrigerator 10 may also be provided with a controller 300 and a timing device 330 and the like.

[0046] The controller 300 includes a memory 320 and a processor 310. The memory 320 stores a control program 321. When the control program 321 is executed by the processor 310, it is used to implement the control method of the ultrasonic assisted processing device 200 of this embodiment. The controller 300 is connected to the ultrasonic generator signal, and is used to provide a control signal to the ultrasonic generator, so as to start and stop the ultrasonic generator and the sound intensity, frequency and other parameters of the ultrasonic signal. The controller 300 can be integrated on the main control board of the refrigerator 10, or it can be separately arranged adjacent to the ultrasonic generator. The controller 300 can further be connected to the main control device signal of the refrigerator 10, provide the main control device with the operating status of the ultrasonic generator, and receive control commands from the main control device.

[0047] The controller 300 may be implemented by various devices having certain data processing capabilities. In a typical configuration, the controller 300 may include a memory 320 , a processor 310 , an input / output interface, and the like.

[0048] The timing device 330 may be a timer, which is mainly used to time the total processing time of the ultrasonic-assisted processing device 200 to avoid inadequate food processing due to a short total processing time or food processing failure due to a long total processing time.

[0049] As mentioned above, when the ultrasonic-assisted processing device 200 is used to process food, the ultrasonic transducer will generate a large amount of heat due to continuous vibration. The heat is transferred to the food through the tray, which will cause the temperature of the food to rise. Excessive temperature will affect the processing quality of the food. Therefore, in order to solve this problem, the present invention reasonably sets the start-up ratio of the ultrasonic-assisted processing device 200, controls the ultrasonic-assisted processing device 200 to operate according to the set start-up ratio cycle, so that the temperature of the ultrasonic-assisted processing device 200 is maintained at the optimal processing temperature of the food to be processed. This part of the content will be described in detail later.

[0050] Figure 3 is a schematic diagram of a control method of an ultrasound-assisted processing device 200 according to an embodiment of the present invention. The control method at least includes the following steps S102 to S106.

[0051] Step S102, obtaining target processing parameters of the food to be processed and environmental parameters of the refrigerator 10.

[0052] In this step, the target processing parameters of the food to be processed can be

[0053] Step S104, determining a target startup ratio of the ultrasound-assisted processing device 200 according to the target processing parameters and the environmental parameters.

[0054] Step S106, controlling the ultrasound-assisted processing device 200 to operate according to the target startup ratio cycle.

[0055] The control method of the ultrasonic assisted processing device 200 of the present invention first obtains the target processing parameters of the food to be processed and the environmental parameters of the refrigerator 10, and then determines the target start-up ratio of the ultrasonic assisted processing device 200 according to the target processing parameters and the environmental parameters, so that when the ultrasonic assisted processing device 200 is controlled to operate according to the target start-up ratio cycle, in this way, the target start-up ratio of the ultrasonic assisted processing device 200 can be determined more reasonably, and the ultrasonic assisted processing device 200 will not have an adverse effect on the processing quality of the food during the operation according to the target start-up ratio.

[0056] In the above step S102, the target processing parameters of the food to be processed may include the target processing power and the target processing temperature of the food to be processed, that is, the optimal processing power and the optimal processing temperature of the food. The environmental parameters for the operation of the refrigerator 10 may include the external temperature of the refrigerator 10, the external humidity and the internal temperature of the storage compartment 110. The step of determining the target startup ratio of the ultrasonic-assisted processing device 200 according to the target processing parameters and the environmental sampling parameters may be to find out the target startup ratio from the pre-stored relationship table according to the external temperature of the refrigerator 10, the external humidity, the internal temperature of the storage compartment 110 and the target processing power, so that the ultrasonic-assisted processing device 200 can maintain its own temperature at the target processing temperature during the operation according to the target startup ratio cycle.

[0057] In this embodiment, for different types of food, the target processing power and target processing temperature can be obtained by experiment, and the temperature of the ultrasonic-assisted processing device 200 is maintained at the target processing temperature of the food by adjusting the target startup ratio of the ultrasonic-assisted processing device 200. In actual application, the inventors found that the external temperature, external humidity and temperature of the storage compartment 110 of the refrigerator 10 will have a certain impact on the temperature of the ultrasonic-assisted processing device 200. For example, the external temperature of the refrigerator 10 is high, the external humidity is low, and the temperature of the storage compartment 110 is high, which will cause the heat dissipation effect of the ultrasonic-assisted processing device 200 to deteriorate, and then cause the actual temperature of the ultrasonic-assisted processing device 200 to be higher than the target processing temperature of the food when the ultrasonic-assisted processing device 200 is running according to the target startup ratio.

[0058] Specifically, since the tray is arranged in the storage compartment 110 and the ultrasonic transducer is arranged at the bottom of the tray, the heat generated by the ultrasonic transducer is directly transferred to the tray and eventually reaches equilibrium with the temperature of the tray. Therefore, the temperature of the storage compartment 110 is the main factor affecting the heat dissipation effect of the ultrasonic transducer. The ultrasonic generator is arranged on the back side of the refrigerator 10, and the external temperature and humidity of the refrigerator 10 are the main factors affecting the heat dissipation effect of the ultrasonic generator. While ensuring that the heat generated by the ultrasonic transducer acts on the tray to maintain the temperature of the tray at the target processing temperature of the food to be processed, the normal operation of the ultrasonic generator should also be ensured to avoid overheating and damage of the ultrasonic generator or entering the overheating protection mode.

[0059] In order to solve the above problems, the present invention uses the environmental parameters of the operation of the refrigerator 10 and the target processing power of the food to be processed as the basis for determining the target start-up ratio of the ultrasonic assisted processing device 200. For different food materials and different environmental parameters, the target start-up ratio control of the ultrasonic assisted processing device 200 can be seen in the table below.

[0060] Table 1: Target startup ratio of the ultrasound-assisted treatment device 200 under different environmental parameters

[0061]

[0062] As can be seen from the above table, when the internal temperature of the storage compartment 110 is constant and the external temperature of the refrigerator 10 increases, the target startup ratio of the ultrasonic-assisted processing device 200 needs to be lowered. When the external temperature of the refrigerator 10 is constant and the internal temperature of the storage compartment 110 increases, the startup ratio of the ultrasonic-assisted processing device 200 also needs to be lowered. Since the external humidity of the refrigerator 10 has a relatively small effect on the ultrasonic-assisted processing device 200, although it is not shown in the above table, it can be understood that when the external humidity of the refrigerator 10 is large, the heat dissipation effect of the ultrasonic generator can be improved, so that the ultrasonic-assisted processing device 200 can be started and operated according to a larger target. Of course, when the target processing power of the food to be processed is high, the heat generation of the ultrasonic-assisted processing device 200 increases when it runs at the target processing power. Therefore, it is necessary to appropriately reduce the startup ratio of the ultrasonic-assisted processing device 200.

[0063] In order to shorten the processing cycle of food materials and improve the processing efficiency of food materials, in the step of controlling the ultrasonic-assisted processing device 200 to operate according to the target start-up ratio cycle, the internal temperature of the storage compartment 110 can also be lowered, and then the target start-up ratio can be re-determined according to the lowered internal temperature of the storage compartment 110. That is to say, in some cases, such as when the user needs to process the food materials as soon as possible for consumption, the temperature of the storage compartment 110 can be lowered. The temperature of the storage compartment 110 is generally around 9°C. At this time, the temperature of the storage compartment 110 can be lowered to 1°C, thereby improving the heat dissipation effect of the ultrasonic-assisted processing device 200, so that when the ultrasonic-assisted processing device 200 operates according to a higher target start-up ratio, the temperature of the ultrasonic-assisted processing device 200 can still be maintained at the target processing temperature of the food materials to be processed. In this way, the processing efficiency of the food materials to be processed is improved, and the adverse effect of the temperature of the ultrasonic-assisted processing device 200 on the quality of the food materials is avoided.

[0064] Since the total processing time of food is also an important factor affecting the quality of food, too long or too short total processing time of food will affect the taste of the food. Therefore, in this embodiment, the target processing parameter also includes a target processing time. After the step of controlling the ultrasonic-assisted processing device 200 to operate according to the target startup ratio cycle, the total processing time of the ultrasonic-assisted processing device 200 should be accumulated. When the total processing time of the ultrasonic-assisted processing device 200 reaches the target processing time, the ultrasonic-assisted processing device 200 is turned off, thereby ensuring that the total processing time of the food to be processed is appropriate.

[0065] Specifically, the step of accumulating the total processing time of the ultrasonic-assisted processing device 200 may be to start a timer while the ultrasonic-assisted processing device 200 is running, and the total time of the timer is used as the total processing time of the ultrasonic-assisted processing device 200. It should be noted that the total processing time only includes the various time periods when the ultrasonic-assisted processing device 200 is started and processes the food to be processed, and does not include the time of shutdown and cooling. By comparing the total processing time of the ultrasonic-assisted processing device 200 with the target processing time of the food to be processed, when the total processing time of the ultrasonic-assisted processing device 200 reaches the target processing time of the food to be processed, it can be basically determined that the food to be processed has been processed.

[0066] In a preferred embodiment, before the step of obtaining the target processing parameters of the food to be processed and the environmental parameters for the operation of the refrigerator 10, it is also possible to determine whether the type information of the food to be processed selected by the user is obtained, and then the target processing parameters of the food to be processed and the environmental parameters for the operation of the refrigerator 10 are obtained accordingly according to the obtained type information of the food to be processed. In this embodiment, the type information of the food to be processed can be chicken, fish, beef, etc. By selecting the type information of the food to be processed, the pre-stored target processing parameters corresponding to the food to be processed can be automatically obtained without manual setting, which is simple and convenient.

[0067] Furthermore, after the step of determining whether the type information of the food to be processed selected by the user is obtained, if the type information of the food to be processed is not obtained, that is, the user has not selected the type information of the food, the refrigerator 10 is controlled to emit a prompt sound to remind the user to select the type information of the food to be processed in time.

[0068] In an optional embodiment, before determining whether the type information of the food to be processed selected by the user is obtained, it can also be determined whether food is placed in the ultrasonic-assisted processing device 200. Only when it is determined that food has been placed in the ultrasonic-assisted processing device 200, the type information of the food to be processed selected by the user is obtained, so as to avoid selecting the type information of the food when the food is forgotten to be placed, causing the ultrasonic-assisted processing device 200 to run at no load.

[0069] Specifically, the step of determining whether food is placed in the ultrasonic-assisted processing device 200 may be to obtain sensing data of a capacitive sensor or a probe sensor disposed in the ultrasonic-assisted processing device 200, and determine whether food is placed in the ultrasonic-assisted processing device 200 based on the sensing data. In this embodiment, the probe of the capacitive sensor or the probe sensor may be exposed in the tray of the ultrasonic-assisted processing device 200. In the two cases where food to be processed is placed in the tray and when food to be processed is not placed in the tray, the sensing data (specifically dielectric constant) obtained by the capacitive sensor or the probe sensor is different, so it can be effectively distinguished.

[0070] Figure 4 2 is a flow chart of a control method of an ultrasound-assisted processing device 200 according to an embodiment of the present invention. The control method at least includes the following steps S202 to S222.

[0071] Step S202 : acquiring sensing data of a capacitive sensor or a probe sensor disposed in the ultrasound-assisted processing device 200 .

[0072] In this step, the probe of the capacitive sensor or the probe sensor can be exposed in the tray of the ultrasound-assisted processing device 200 to obtain sensing data.

[0073] Step S204, judging whether food is placed in the ultrasonic assisted processing device 200 according to the sensing data, and if so, executing step S206.

[0074] In this step, in the two cases where the food to be processed is placed in the tray and the food to be processed is not placed in the tray, the sensing data (specifically the dielectric constant) obtained by the capacitive sensor or the probe sensor is different, so it can be effectively distinguished.

[0075] Step S206, determining whether the type information of the food to be processed selected by the user is obtained, if so, executing step S208, if not, executing step S222.

[0076] In this step, the type information of the food to be processed may be chicken, fish, beef, etc. By selecting the type information of the food to be processed, the pre-stored target processing parameters corresponding to the food to be processed can be automatically obtained without manual setting, which is simple and convenient.

[0077] Step S208, obtaining the target processing power, target processing temperature and target processing time of the food to be processed.

[0078] The target processing power, target processing temperature and target processing time in this step correspond to the optimal processing power, optimal processing temperature and optimal processing time of the food to be processed. The processing quality of the food to be processed is best under the optimal processing power, optimal processing temperature and optimal processing time.

[0079] Step S210 , obtaining the external temperature and external humidity of the refrigerator 10 and the internal temperature of the storage compartment 110 .

[0080] Step S212, according to the external temperature and external humidity of the refrigerator 10, the internal temperature of the storage compartment 110 and the target processing power of the food to be processed, the target power-on ratio is searched from the pre-stored relationship table.

[0081] In this step, under the current environmental conditions of the external temperature, external humidity and internal temperature of the storage compartment 110 of the refrigerator 10, when the ultrasonic assisted processing device 200 operates according to the target processing power and target start-up ratio, its own temperature should ultimately be maintained at the target processing temperature of the food to be processed to ensure the processing quality of the food to be processed.

[0082] Step S214, controlling the ultrasound-assisted processing device 200 to operate according to the target startup ratio cycle.

[0083] Step S216, accumulating the total processing time of the ultrasound-assisted processing device 200.

[0084] In this step, the total processing time of the ultrasonic-assisted treatment device 200 refers to the total processing time of the ultrasonic-assisted treatment device 200 during the startup process, and the shutdown cooling time is not included.

[0085] Step S218, determining whether the total processing time of the ultrasound-assisted processing device 200 reaches the target processing time, if so, executing step S220, if not, returning to step S216.

[0086] Step S220 , turning off the ultrasound-assisted processing device 200 .

[0087] After actual use of trial samples, the control method of the refrigerator 10 and its ultrasonic-assisted processing device 200 of this embodiment can determine the target start-up ratio of the ultrasonic-assisted processing device 200 according to the target processing parameters of the food to be processed and the environmental parameters of the operation of the refrigerator 10, so that when the ultrasonic-assisted processing device 200 is operating according to the target start-up ratio, the temperature of the ultrasonic-assisted processing device 200 can be maintained at the target processing temperature of the food to be processed, and the processing power and total processing time of the ultrasonic-assisted processing device 200 are respectively the same as the target processing power and target processing time of the food to be processed, thereby ensuring the processing quality of the food.

[0088] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention.
