DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure is not limited to the embodiments herein, but may be embodied in various forms. Rather, these embodiments are provided to more thoroughly understand the present disclosure and fully convey the scope of the present disclosure to those skilled in the art.

[0023] In order to solve the above problems, the present invention provides a refrigerator 10. Figure 1 is a schematic structural diagram of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 generally includes a body 100, in which one or more storage compartments 110 are formed, and the storage compartments 110 form a refrigeration compartment, a freezer compartment, a temperature-variable compartment, etc. according to the freezing temperature. Specifically, the number, functions, and layout manner of the storage compartments 110 can be set as required.

[0024] The refrigerator 10 of the present invention may further include an ultrasonic auxiliary processing device 200 (not shown in FIG. 1). In this embodiment, the ultrasonic auxiliary processing device 200 may be directly disposed in the refrigerator compartment of the refrigerator 10, or may be disposed in the refrigerator compartment so that it can be pulled out like a drawer. Of course, in other cases, the ultrasonic auxiliary processing device 200 may be disposed in the freezer compartment or the temperature variable compartment of the refrigerator 10. The functions of the ultrasonic auxiliary processing device 200 include, but are not limited to, soaking assistance, freezing assistance, cleaning assistance, etc.

[0025] Specifically, the ultrasonic assisted processing device 200 includes at least a tray, an ultrasonic generator, and an ultrasonic transducer, and the tray is placed in the refrigerator (or freezer) and used to place the food to be processed. The ultrasonic transducer is placed at the bottom of the tray, and the ultrasonic generator is placed on the rear side of the refrigerator 10 and electrically connected to the ultrasonic transducer. By supplying ultrasonic electric energy to the ultrasonic transducer, the ultrasonic transducer vibrates to provide marinating (or freezing) assistance for the food. Note that the operating principle of the ultrasonic assisted processing device 200 is well known to those skilled in the art, and will not be repeated in this specification.

[0026] In addition, during the operation of the ultrasonic auxiliary processing device 200, both the ultrasonic generator and the ultrasonic vibrator may be damaged by overheating, so the ultrasonic generator and the ultrasonic vibrator need to be protected separately. The ultrasonic generator is disposed on the rear side of the refrigerator 10 (for example, the rear panel of the refrigerator 10), and the temperature and humidity outside the refrigerator 10 are the main factors affecting the activation ratio of the ultrasonic generator. When the external temperature is low or the humidity is high, the heat dissipation effect of the ultrasonic generator is improved, and the maximum activation ratio of the ultrasonic generator is relatively large correspondingly. The ultrasonic vibrator is disposed in the refrigerator compartment of the refrigerator 10, and it has been experimentally found that the temperature inside the refrigerator compartment is the main factor affecting the activation ratio of the ultrasonic vibrator, and the humidity inside the refrigerator compartment has a small effect on the activation ratio of the ultrasonic vibrator. Therefore, in this embodiment, the temperature and humidity outside the refrigerator 10 and the temperature inside the refrigerator compartment of the refrigerator 10 are used as control standards for controlling the activation ratio threshold of the ultrasonic auxiliary processing device 200, and the ultrasonic auxiliary processing device 200 periodically operates within the range of the activation ratio threshold, thereby ensuring the normal progress of the processing operation and preventing the ultrasonic auxiliary processing device 200 from being damaged by overheating.

[0027] 2 is a schematic block diagram of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 may further include a controller 300, a temperature detector 330, and a humidity detector 340.

[0028] The controller 300 includes a memory 320 and a processor 310. A control program 321 is stored in the memory 320. When the control program 321 is executed by the processor 310, the control method of the ultrasonic auxiliary processing device 200 of this embodiment is realized. The controller 300 is signal-connected to the ultrasonic generator, and provides a control signal to the ultrasonic generator, which is used to turn the ultrasonic generator on and off, and adjust parameters such as the acoustic intensity and frequency of the ultrasonic signal. The controller 300 may be integrated on the main control board of the refrigerator 10, or may be provided separately adjacent to the ultrasonic generator. The controller 300 is further signal-connected to the main control device of the refrigerator 10, and is used to provide the operating state of the ultrasonic generator to the main control device and receive control commands from the main control device.

[0029] The controller 300 may be implemented by a variety of devices having certain data processing capabilities, and in one typical arrangement, the controller 300 may include a memory 320, a processor 310, input / output interfaces, etc.

[0030] The temperature outside the refrigerator 10 and the temperature inside the refrigerator compartment may be detected by various temperature detection devices 330, such as temperature sensors. The humidity outside the refrigerator 10 may be detected by various humidity detection devices 340, such as humidity sensors.

[0031] 3 is a schematic diagram of a control method for the ultrasonic auxiliary processing device 200 according to an embodiment of the present invention. The control method includes at least the following steps S102 to S108.

[0032] Step S102: The ultrasonic auxiliary processing device 200 is started.

[0033] Step S104: The operating environment parameters of the refrigerator 10 are acquired.

[0034] Step S106: Determine the activation ratio threshold of the ultrasonic auxiliary processing device 200 based on the operating environment parameters of the refrigerator 10. In this step, the activation ratio threshold refers to the maximum activation ratio (operating time: stop time) allowed by the ultrasonic auxiliary processing device 200 under the current environmental parameters, and during the process of the ultrasonic auxiliary processing device 200 operating at the maximum activation ratio, the ultrasonic vibrator will not be damaged due to overheating, and the ultrasonic generator will not enter a protection mode or be damaged due to overheating.

[0035] Step S108: The ultrasonic auxiliary processing device 200 is controlled to operate periodically within the range of the activation ratio threshold.

[0036] In the control method for the ultrasonic auxiliary processing device 200 of the present invention, during the processing of ingredients, the ultrasonic auxiliary processing device 200 is first started, and then the operating environment parameters of the refrigerator 10 are obtained, and the starting ratio threshold of the ultrasonic auxiliary processing device 200 is determined according to the operating environment parameters of the refrigerator 10, and the ultrasonic auxiliary processing device 200 is controlled to operate periodically within the range of the starting ratio threshold, and the ultrasonic auxiliary processing device 200 is periodically turned on and off. In this way, the ultrasonic auxiliary processing device 200 can be stopped and cooled in a timely manner, damage caused by overheating can be avoided, and the normal progress of the processing operation can be ensured.

[0037] In an optional embodiment, the operating environment parameters of the refrigerator 10 may include the temperature and humidity outside the refrigerator 10. The step of determining the activation ratio threshold of the ultrasonic auxiliary processing device 200 based on the operating environment parameters of the refrigerator 10 may be to obtain the temperature and humidity outside the refrigerator 10 and then determine the activation ratio threshold of the ultrasonic auxiliary processing device 200 based on the temperature and humidity outside the refrigerator 10. By determining the activation ratio threshold of the ultrasonic auxiliary processing device 200 based on the temperature and humidity outside the refrigerator 10, it is possible to effectively prevent the ultrasonic generator of the ultrasonic auxiliary processing device 200 from entering an overheating protection mode or being damaged due to overheating.

[0038] In another selectable embodiment, the operating environment parameters of the refrigerator 10 may include an internal temperature of the refrigerator compartment of the refrigerator 10. The step of determining the activation ratio threshold of the ultrasonic auxiliary processing device 200 based on the operating environment parameters of the refrigerator 10 may be to obtain the internal temperature of the refrigerator compartment of the refrigerator 10, and then determine the activation ratio threshold of the ultrasonic auxiliary processing device 200 based on the internal temperature of the refrigerator compartment of the refrigerator 10. By determining the activation ratio threshold of the ultrasonic auxiliary processing device 200 based on the internal temperature of the refrigerator compartment of the refrigerator 10, it is possible to effectively avoid the ultrasonic transducer of the ultrasonic auxiliary processing device 200 from being damaged due to overheating.

[0039] In a specific embodiment, the operating environment parameters of the refrigerator 10 include the temperature inside the refrigerator compartment of the refrigerator 10 in addition to the temperature and humidity outside the refrigerator 10. Figure 4 is a flowchart of a method for determining an activation ratio threshold according to an embodiment of the present invention. As shown in Figure 4, the step of determining the activation ratio threshold of the ultrasonic auxiliary processing device 200 based on the operating environment parameters of the refrigerator 10 includes the following steps S202 to S214.

[0040] Step S202: The temperature and humidity outside the refrigerator 10 are acquired.

[0041] Step S204: Determine a first activation ratio of the ultrasonic auxiliary processing device 200 based on the temperature and humidity outside the refrigerator 10. In this step, the first activation ratio is the maximum activation ratio at which the ultrasonic generator of the ultrasonic auxiliary processing device 200 can operate under the current temperature and humidity conditions outside the refrigerator 10, and the ultrasonic generator will not be damaged by overheating when it periodically operates at the maximum activation ratio.

[0042] Step S206: The temperature inside the refrigerator compartment of the refrigerator 10 is acquired.

[0043] Step S208: Determine a second startup ratio of the ultrasonic auxiliary processing device 200 based on the internal temperature of the refrigerator compartment of the refrigerator 10. In this step, the second startup ratio is the maximum startup ratio at which the ultrasonic vibrator of the ultrasonic auxiliary processing device 200 can operate under the current internal temperature condition of the refrigerator compartment of the refrigerator 10, and the ultrasonic vibrator will not be damaged by overheating when it periodically operates at the maximum startup ratio.

[0044] Step S210: Determine whether the first activation ratio is smaller than the second activation ratio, and if so, execute step S212; if not, execute step S214.

[0045] Step S212: The first invocation ratio is set as the invocation ratio threshold value.

[0046] Step S214: The second invocation ratio is set as the invocation ratio threshold value.

[0047] By comparing the first activation ratio and the second activation ratio, the smaller of the two is set as the activation ratio threshold when the ultrasonic auxiliary processing device 200 finally operates, which not only prevents the ultrasonic generator from being damaged due to overheating during the operation process during the processing of food ingredients, but also prevents the ultrasonic vibrator from being damaged during the operation process, thereby contributing to the smooth progress of the processing operation.

[0048] In step S108, the step of controlling the ultrasonic auxiliary processing device 200 to operate periodically within the range of the startup ratio threshold may be to obtain a current startup ratio of the ultrasonic auxiliary processing device 200, compare the current startup ratio of the ultrasonic auxiliary processing device 200 with the startup ratio threshold, and if the current startup ratio of the ultrasonic auxiliary processing device 200 is higher than the startup ratio threshold, reduce the current startup ratio of the ultrasonic auxiliary processing device 200 to the startup ratio threshold, thereby avoiding the ultrasonic auxiliary processing device 200 from being damaged due to overheating after continuous operation.

[0049] Furthermore, after the step of comparing the current startup ratio of the ultrasonic auxiliary processing device 200 with the startup ratio threshold, if the current startup ratio of the ultrasonic auxiliary processing device 200 is lower than the startup ratio threshold, the current startup ratio of the ultrasonic auxiliary processing device 200 can be maintained as is, so that the ultrasonic auxiliary processing device 200 will not be damaged due to overheating during the operation process, or the current startup ratio can be increased to the startup ratio threshold, so that the food processing cycle can be shortened to the maximum extent and the food processing efficiency can be improved.

[0050] In some embodiments, the step of reducing the current activation ratio of the ultrasonic auxiliary processing device 200 to the activation ratio threshold may be shortening the operation time of the ultrasonic auxiliary processing device 200, or extending the stop time of the ultrasonic auxiliary processing device 200, or shortening the operation time of the ultrasonic auxiliary processing device 200 while simultaneously extending the stop time of the ultrasonic auxiliary processing device 200.

[0051] In this embodiment, before the step of starting the ultrasonic auxiliary processing device 200, it may be determined whether or not food ingredients are placed in the tray of the ultrasonic auxiliary processing device 200, and if it is determined that the food ingredients are placed in the specified position, the ultrasonic auxiliary processing device 200 is started and the ultrasonic auxiliary processing device 200 is prevented from operating in idle.

[0052] Specifically, the step of determining whether ingredients are placed on the tray of the ultrasonic auxiliary processing device 200 may involve obtaining sensing data from a capacitance sensor or a probe sensor arranged on the tray, and then determining whether ingredients to be processed are placed on the tray based on the sensing data. When ingredients are placed on the tray or not, the dielectric constants obtained by the capacitance sensor or the probe sensor are different, so that it is possible to effectively distinguish between the case where ingredients are placed on the tray and the case where ingredients are not placed on the tray.

[0053] 5 is a flowchart of a control method for the ultrasound auxiliary processing device 200 according to an embodiment of the present invention. The control method includes at least the following steps S302 to S326.

[0054] Step S302: Sensing data from a capacitance sensor or a probe sensor arranged on the tray is acquired.

[0055] Step S304: It is determined based on the sensing data whether the food material to be processed is placed in the tray, and if so, step S306 is executed.

[0056] Step S306: The ultrasonic auxiliary processing device 200 is started.

[0057] Step S308: The temperature and humidity outside the refrigerator 10 are acquired.

[0058] Step S310: Determine a first activation ratio of the ultrasonic auxiliary processing device 200 based on the temperature and humidity outside the refrigerator 10. In this step, the first activation ratio is the maximum activation ratio at which the ultrasonic generator of the ultrasonic auxiliary processing device 200 can operate under the current temperature and humidity conditions outside the refrigerator 10, and when the ultrasonic generator periodically operates at the maximum activation ratio, no damage due to overheating occurs.

[0059] Step S312: The temperature inside the refrigerator compartment of the refrigerator 10 is acquired.

[0060] Step S314: Determine a second startup ratio of the ultrasonic auxiliary processing device 200 based on the internal temperature of the refrigerator compartment of the refrigerator 10. In this step, the second startup ratio is the maximum startup ratio at which the ultrasonic vibrator of the ultrasonic auxiliary processing device 200 can operate under the current internal temperature condition of the refrigerator compartment of the refrigerator 10, and no damage due to overheating occurs when the ultrasonic vibrator periodically operates at the maximum startup ratio.

[0061] Step S316: The smaller of the first activation ratio and the second activation ratio is set as the activation ratio threshold of the ultrasonic auxiliary processing device 200.

[0062] The order of steps S308 to S310 and steps S312 to S314 may be interchanged, that is, the order of determining the first startup ratio and the second startup ratio may be interchanged, and is not particularly limited in this embodiment.

[0063] Step S318: The current activation ratio of the ultrasonic auxiliary processing device 200 is obtained.

[0064] Step S320: Determine whether the current activation ratio of the ultrasound auxiliary processing device 200 is higher than the activation ratio threshold, and if so, execute step S322; if not, execute step S324.

[0065] Step S322: Reduce the current invocation ratio to the invocation ratio threshold, and execute step S326.

[0066] Step S324: The current invocation ratio is maintained as is, and step S326 is executed. In this step, the current invocation ratio may be appropriately increased. For example, by increasing it to the invocation ratio threshold, the ingredient processing cycle can be shortened to the maximum, and the ingredient processing efficiency can be improved.

[0067] Step S326: Control the ultrasonic auxiliary processing device 200 to operate at a predetermined cycle, and return to step S308. In this step, after controlling the ultrasonic auxiliary processing device 200 to operate at a predetermined cycle, the operating environment parameters of the refrigerator 10 are detected again, which can prevent the activation ratio of the ultrasonic auxiliary processing device 200 from being frequently adjusted, which is beneficial to the stability of food processing.

[0068] In this embodiment, the temperature and humidity outside the refrigerator 10, as well as the temperature inside the refrigerator compartment of the refrigerator 10, are used as control standards for the start-up ratio threshold of the ultrasonic auxiliary processing device 200, and the ultrasonic auxiliary processing device 200 is controlled to operate periodically within the range of the start-up ratio threshold, thereby ensuring normal progress of the processing operation and preventing the ultrasonic auxiliary processing device 200 from being damaged due to continuous overheating.
