Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
To solve the above problems, the present invention provides a refrigerator 10. Fig. 1 is a schematic structural view of a refrigerator 10 according to one embodiment of the present invention. The refrigerator 10 may generally include a cabinet 100, wherein one or more storage compartments 110 are formed in the cabinet 100, and the storage compartments 110 may be configured to form a refrigerated storage space, a frozen storage space, a variable-temperature storage space, and the like according to a refrigerating temperature. Specifically, the number, functions and layout of the storage compartments 110 may be configured as required.
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 is disposed in the refrigerated storage space of the refrigerator 10, and of course, in some cases, the ultrasonic auxiliary processing device 200 may also be disposed in the frozen storage space or the temperature-variable storage space, and the functions of the ultrasonic auxiliary processing device 200 include, but are not limited to, auxiliary curing, auxiliary freezing, and the like. The ultrasonic auxiliary treatment device 200 may be carried in the refrigerated storage space in the form of a drawer or directly placed in the refrigerated storage space.
The ultrasonic auxiliary processing device 200 at least comprises a tray, an ultrasonic generator and an ultrasonic transducer, wherein the tray can be arranged in the refrigerated storage space (or the frozen storage space) and is used for bearing food materials to be processed. The ultrasonic transducer can be arranged at the bottom of the tray, the ultrasonic generator can be arranged at the back side of the refrigerator 10 and electrically connected with the ultrasonic transducer, and the ultrasonic transducer is provided with ultrasonic frequency electric energy to vibrate, so that auxiliary pickling (or auxiliary freezing) of food materials is realized. It should be noted that the working principle of the ultrasonic auxiliary treatment device 200 is well known to those skilled in the art, and will not be described herein.
The inventor finds that, after the ultrasonic auxiliary processing device 200 is disposed in the refrigerator 10, the tray is not enough to contain a large amount of water to dissipate heat of the ultrasonic transducer, heat generated by continuous vibration of the ultrasonic transducer is transferred to the food material through the tray, and when the temperature of the tray exceeds a certain temperature, the processing quality of the food material is affected. Therefore, in the actual processing process, the ultrasonic auxiliary processing device 200 needs to be turned off at intervals, so that the ultrasonic auxiliary processing device 200 is stopped and cooled, and is operated again after the temperature is reduced, and the operation is repeated, so that the processing period of the food material is longer, and the processing efficiency of the food material is not improved. Based on this, in the present invention, by acquiring the operation parameters of the ultrasonic auxiliary processing device 200, and dynamically adjusting the power-on ratio of the ultrasonic auxiliary processing device 200 according to the operation parameters, the power-off cooling time of the ultrasonic auxiliary processing device 200 is shortened, and thus the food material processing cycle is shortened to the greatest extent, which will be described in detail later.
Fig. 2 is a schematic block diagram of a refrigerator 10 according to one embodiment of the present invention. Further, the refrigerator 10 may be further provided with a controller 300, a temperature detecting device 330, a timing device 340, and the like.
The controller 300 includes a memory 320 and a processor 310, wherein a control program 321 is stored in the memory 320, and the control program 321 is used for implementing the overheating protection method of the ultrasound auxiliary treatment device 200 according to the embodiment when being executed by the processor 310. The controller 300 is in signal connection with the ultrasonic generator and is used for providing a control signal to the ultrasonic generator so as to start and stop the ultrasonic generator and parameters of the ultrasonic signal such as sound intensity, frequency and the like. The controller 300 may be integrated on the main control board of the refrigerator 10 or may be separately provided adjacent to the ultrasonic generator. The controller 300 may further be in signal communication with a master control device of the refrigerator 10, providing the operating state of the ultrasonic generator to the master control device, and receiving control commands from the master control device.
The controller 300 may be implemented by various devices having certain data processing capabilities, and in a typical configuration, the controller 300 may include a memory 320, a processor 310, input/output interfaces, and the like.
The overheat protection method of the ultrasonic auxiliary processing device 200 of the present embodiment uses the temperature of the tray as the control basis for dynamically adjusting the power-on ratio of the ultrasonic auxiliary processing device 200. The detection of the temperature of the tray may be achieved by various temperature detecting means 330, for example, a temperature sensor, etc. In some preferred embodiments, the temperature sensor can be arranged at the bottom of the tray, and in the embodiment, the tray is made of a metal material, so that the heat transfer performance is better. Therefore, the temperature sensor may be provided on the outer periphery of the tray. The timing device 340 may be a timer, and the running time of the ultrasonic auxiliary processing device 200 is accumulated by the timer, and when the total running time of the ultrasonic auxiliary processing device 200 reaches the processing time required by the food material, which represents that the food material has been processed, the ultrasonic auxiliary processing device 200 may be turned off.
FIG. 3 is a schematic diagram of a method of ultrasound assisted treatment device 200 over-temperature protection, according to one embodiment of the present invention. The method includes at least the following steps S102 to S106.
In step S102, the ultrasound auxiliary processing device 200 is operated at the initial power-on ratio.
In this step, since the initial boot ratio is affected by the temperature and humidity of the external environment of the refrigerator 10 and the temperature in the refrigerated storage space, the initial boot ratios at different environmental temperatures and humidities are different. In the present embodiment, the initial power-on ratio is 1.
Step S104, acquiring the operation parameters of the ultrasonic auxiliary processing device 200, and adjusting the power-on ratio of the ultrasonic auxiliary processing device 200 according to the operation parameters of the ultrasonic auxiliary processing device 200.
Step S106, accumulating the total processing time of the ultrasonic auxiliary processing device 200, and turning off the ultrasonic auxiliary processing device 200 until the total processing time of the ultrasonic auxiliary processing device 200 reaches the preset processing time.
In this step, the preset processing time refers to the time required for the food material to continue to be processed until the processing is completed under ideal conditions. Of course, since the preset processing time of different food materials may also be different, the specific value of the preset processing time may be set according to the type of the food material.
The overheating protection method of the ultrasonic auxiliary processing device 200 comprises the steps of firstly operating the ultrasonic auxiliary processing device 200 according to an initial startup ratio, acquiring operation parameters of the ultrasonic auxiliary processing device 200 in the operation process, then adjusting the startup ratio of the ultrasonic auxiliary processing device 200 according to the operation parameters of the ultrasonic auxiliary processing device 200, accumulating the total processing time of the ultrasonic auxiliary processing device 200, and turning off the ultrasonic auxiliary processing device 200 until the total processing time of the ultrasonic auxiliary processing device 200 reaches the preset processing time. According to the overheating protection method provided by the embodiment, the shutdown cooling time of the ultrasonic auxiliary processing device 200 is shortened by dynamically adjusting the starting ratio of the ultrasonic auxiliary processing device 200, so that the total time required for completing food material processing can be shortened to the greatest extent, and the food material processing efficiency is remarkably improved.
In step S104, the operation parameters of the ultrasonic auxiliary processing device 200 mainly include the temperature of the ultrasonic auxiliary processing device 200, and the step of adjusting the power-on ratio of the ultrasonic auxiliary processing device 200 according to the operation parameters of the ultrasonic auxiliary processing device 200 may be acquiring the temperature of the ultrasonic auxiliary processing device 200, and comparing the temperature of the ultrasonic auxiliary processing device 200 with a first preset temperature. If the temperature of the ultrasonic auxiliary processing device 200 is higher than the first preset temperature, the power-on ratio of the ultrasonic auxiliary processing device 200 is adjusted to be low. If the temperature of the ultrasonic auxiliary processing device 200 is lower than the second preset temperature, the power-on ratio of the ultrasonic auxiliary processing device 200 is increased. The first preset temperature is a critical temperature, and may also be understood as a maximum operation temperature allowed by the ultrasonic auxiliary processing device 200, and below the first preset temperature, the quality of the food material is not substantially affected in the processing process. The first preset temperature can be measured through experimental data, the first preset temperatures of different food materials can be different, and the second preset temperature can be lower than the first preset temperature by 3-15 ℃.
In an alternative embodiment, the step of acquiring the temperature of the ultrasonic auxiliary treatment device 200 may be acquiring a detection value of a temperature sensor provided at the periphery of the ultrasonic auxiliary treatment device 200 (specifically, the periphery or the bottom of the tray) and taking the detection value as the temperature of the ultrasonic auxiliary treatment device 200.
In step S106, after the step of accumulating the processing time of the ultrasonic auxiliary processing device 200, it may be determined whether the total processing time of the ultrasonic auxiliary processing device 200 reaches the preset processing time, and if so, the ultrasonic auxiliary processing device 200 is turned off. If not, whether the ultrasonic auxiliary processing device 200 runs the specified cycle at the new power-on ratio is judged, after the ultrasonic auxiliary processing device 200 runs the specified cycle at the new power-on ratio, the temperature of the ultrasonic auxiliary processing device 200 is obtained again, and the temperature of the ultrasonic auxiliary processing device 200 is compared with the first preset temperature. By controlling the ultrasonic auxiliary processing device 200 to run the designated cycle at the new power-on ratio, frequent adjustment of the power-on ratio of the ultrasonic auxiliary processing device 200 can be avoided so as not to affect the stability of food material processing.
Alternatively, the step of accumulating the processing time of the ultrasonic auxiliary processing device 200 may be to switch the timer while switching the ultrasonic auxiliary processing device 200, and take the total timed time of the timer as the total processing time of the ultrasonic auxiliary processing device 200.
Preferably, after the food material processing is completed and the ultrasonic auxiliary processing device 200 is turned off, it may also be displayed on the display interface of the refrigerator 10 that the ultrasonic auxiliary processing device 200 is in a processing completed state, prompting the user that the current food material has been processed.
Further, after the food material processing is completed and the ultrasonic auxiliary processing device 200 is turned off, the refrigerator 10 may be controlled to emit a processing completion prompt sound, so that the user can take out the processed food material in time.
In a preferred embodiment, before the ultrasonic auxiliary processing device 200 is operated at the initial power-on ratio, it is further determined whether the food material is placed in the ultrasonic auxiliary processing device 200, and if it is determined that the food material is placed in place, the operation of the ultrasonic auxiliary processing device 200 at the initial power-on ratio is performed, so that the operation of the ultrasonic auxiliary processing device 200 without the food material is avoided.
Specifically, the step of determining whether the food material is placed in the ultrasonic auxiliary processing device 200 may be acquiring sensing data of a capacitive sensor or a probe-type sensor disposed in the ultrasonic auxiliary processing device 200 (specifically, in a tray), and then determining whether the food material is placed in the ultrasonic auxiliary processing device 200 according to the sensing data. In the present embodiment, the sensing data is specifically dielectric constant, and since the dielectric constants detected by the capacitive sensor and the probe sensor are different in the presence of water or food and in the absence of water or food, it is possible to distinguish whether food is placed in the ultrasonic auxiliary processing device 200.
Fig. 4 is a flow diagram of a method of ultrasound-assisted treatment device 200 over-temperature protection according to one embodiment of the present invention. The method includes at least the following steps S202 to S228.
In step S202, sensing data of a capacitive sensor or a probe sensor provided in the ultrasound-assisted treatment device 200 is acquired.
Step S204, determining whether food material is placed in the ultrasonic auxiliary processing device 200 according to the sensing data, if so, executing step S206.
In step S206, the ultrasound auxiliary processing device 200 is operated at the initial power-on ratio.
In this step, the initial starting-up ratio is affected by the temperature and humidity of the environment outside the refrigerator 10 and the temperature in the refrigerated storage space, and the initial starting-up ratios are different at different environmental temperatures and humidities. In the present embodiment, the initial power-on ratio is described by taking 1.
In step S208, the detection value of the temperature sensor provided on the outer periphery of the ultrasound-assisted treatment device 200 is acquired, and the detection value is taken as the temperature of the ultrasound-assisted treatment device 200.
In this step, the temperature sensor may be specifically disposed on the bottom of the tray or on the outer wall of the tray.
In step S210, it is determined whether the temperature of the ultrasonic auxiliary processing device 200 is higher than a first preset temperature, if so, step S212 is executed, and if not, step S224 is executed.
In this step, the first preset temperature is a critical temperature, which can also be understood as a maximum operation temperature allowed by the ultrasonic auxiliary processing device 200, and below the first preset temperature, the quality of the food material is not substantially affected in the processing process. The first preset temperature can be measured through experimental data, and the first preset temperatures of different food materials can also have differences.
In step S212, the power-on ratio of the ultrasound auxiliary processing device 200 is turned down.
In this step, the power-on ratio of the ultrasonic auxiliary processing device 200 may be adjusted down by shortening the power-on time or by extending the shutdown time.
In step S214, the processing time of the ultrasonic auxiliary processing device 200 is accumulated.
In step S216, it is determined whether the total processing time of the ultrasonic auxiliary processing device 200 reaches the preset processing time, if yes, step S218 is executed, and if no, step S224 is executed.
In this step, the preset processing time refers to the time required for the food material to continue to be processed until the processing is completed under ideal conditions. Of course, since the preset processing time of different food materials may also be different, the specific value of the preset processing time may be set according to the type of the food material.
In step S218, the ultrasonic auxiliary processing device 200 is turned off.
In step S220, the food material is displayed on the display interface of the refrigerator 10 to be processed.
In step S222, the refrigerator 10 sends an alert sound to remind the user to take out the processed food material.
In step S224, it is determined whether the ultrasonic auxiliary processing device 200 has operated the predetermined cycle at the new power-on ratio, and if so, the process returns to step S208, and if not, the process returns to step S214.
In this step, the ultrasound-assisted processing device 200 is controlled to run the designated cycle at the new power-on ratio, so that frequent adjustment of the power-on ratio of the ultrasound-assisted processing device 200 can be avoided, and the stability of food material processing is not affected.
Step S226, determining whether the temperature of the ultrasonic auxiliary processing device 200 is lower than a second preset temperature, if yes, executing step S228, and if no, executing step S214.
In this step, the second predetermined temperature may be 3 to 15 ℃ lower than the first predetermined temperature.
In step S228, the power-on ratio of the ultrasound auxiliary processing device 200 is increased, and then step S214 is executed.
Through the practical use of the trial-produced samples, the refrigerator 10 and the overheat protection method of the ultrasonic auxiliary processing device 200 thereof according to the embodiment can effectively reduce the shutdown cooling time in the food material processing process on the premise of not affecting the quality of the food materials, thereby shortening the food material processing period and improving the processing efficiency of the food materials.
