[0004] However, since the natural frequency of the ultrasonic transducer is fixed and cannot be changed by software, the purpose of a set of ultrasonic equipment is relatively single. For example, the purpose of an ultrasonic cleaning machine is only suitable for cleaning and cannot be used for other purposes such as changing the frequency. If you want to achieve ultrasonic-assisted pickling, you need a new set of equipment, which is not conducive to achieving the multi-functional and multi-purpose purpose of ultrasonic equipment, so it needs to be improved.

[0043] 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.

[0044] 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 cabinet 100, wherein one or more storage compartments are formed in the cabinet 100. The storage compartments may be configured to form a refrigerated storage space 110, a frozen storage space 110, a variable temperature storage space 110, etc. according to the refrigeration temperature. Specifically, the number, function, and layout of the storage compartments may be configured according to requirements.

[0045] The refrigerator 10 of the present invention may further include an ultrasonic auxiliary processing device 200 ( Figure 1 The ultrasonic assisted treatment device 200 is arranged in the refrigerated storage space 110 of the refrigerator 10. Of course, in some cases, the ultrasonic assisted treatment device 200 can also be arranged in the frozen storage space 110 or the variable temperature storage space 110. The functions of the ultrasonic assisted treatment device 200 include but are not limited to assisting pickling, assisting cleaning, assisting atomization, etc. The ultrasonic assisted treatment device 200 can be mounted in the refrigerated storage space 110 in the form of a drawer, or can be directly placed in the refrigerated storage space 110.

[0046] Figure 2 is a schematic structural diagram of an ultrasound base 210 according to an embodiment of the present invention; Figure 3 2 is a schematic diagram of the structure of an ultrasonic container 220 according to an embodiment of the present invention. The ultrasonic assisted treatment device 200 of this embodiment includes an ultrasonic base 210, at least one ultrasonic container 220 used in conjunction with the ultrasonic base 210, and a signal sensing device 230 for detecting the functional type of the ultrasonic container 220. In this embodiment, the ultrasonic base 210 is placed in the storage room, and there can be three ultrasonic containers 220 used in conjunction with the ultrasonic base 210, which can be defined as an ultrasonic pickling container, an ultrasonic cleaning container, and an ultrasonic atomization container.

[0047] In order to facilitate the user to identify ultrasonic containers 220 of different functional types, a label can be set on the shell of the ultrasonic container 220. For example, a label with the word "pickle" can be pasted on the shell of the ultrasonic pickling container, a label with the word "clean" can be pasted on the shell of the ultrasonic cleaning container, and a label with the word "atomize" can be pasted on the shell of the ultrasonic atomization container. If the user wants to pickle the food, the ultrasonic pickling container can be found more conveniently through the label, and then the ultrasonic pickling container can be placed separately on the ultrasonic base 210. Similarly, if the user wants to wash or atomize the food, the corresponding ultrasonic cleaning container or ultrasonic atomization container can be found through the label, and the ultrasonic cleaning container or ultrasonic atomization container can be placed on the ultrasonic base 210. It should be noted that the ultrasonic base 210 can only be used to place ultrasonic containers 220 of one functional type at the same time.

[0048] As mentioned above, since the frequency of the ultrasonic transducer 222 is fixed (natural frequency), it cannot be changed by software. Therefore, a set of ultrasonic equipment can only perform one type of processing work. For example, ultrasonic cleaning equipment can only be used for cleaning food and cannot be used for other purposes. If you want to ultrasonically marinate the food, you need to replace a new set of equipment. In response to this problem, the present invention proposes a solution of an ultrasonic generator 212 matching multiple ultrasonic transducers 222, thereby realizing the multi-functional and multi-purpose switching of the ultrasonic device in the refrigerator 10.

[0049] Specifically, the ultrasonic container 220 includes a container body 221 and an ultrasonic transducer 222, and the ultrasonic transducer 222 is fixed to the bottom of the container body 221. The ultrasonic base 210 includes a base body 211 and an ultrasonic generator 212, and the ultrasonic generator 212 is fixed to the top of the base body 211. By designing the structures of the ultrasonic container 220 and the ultrasonic base 210, when the ultrasonic container 220 is placed on the ultrasonic base 210, the line between the ultrasonic generator 212 and the ultrasonic transducer 222 can be directly connected, and the driving signal generated by the ultrasonic generator 212 can be transmitted to the ultrasonic transducer 222 through the line to drive the ultrasonic transducer 222 to vibrate.

[0050] In a preferred embodiment, the signal sensing device 230 may include two Hall sensors 231, which are embedded in the top of the base body 211, and the probes protrude upward from the upper surface of the base body 211. The bottom of the ultrasonic container 220 is provided with a feature portion, which is configured to be detected and identified by the two Hall sensors 231, so as to determine the functional type of the ultrasonic container 220.

[0051] In a specific embodiment, two Hall sensors 231 are relatively arranged on both sides of the length direction of the base body 211. The characteristic part of the container body 221 can be represented by whether the magnet 241 is set. For example, one side of the length direction of the container body 221 can be defined as the first side, and the other side of the length direction of the container body 221 can be defined as the second side. For an ultrasonic pickling container, the characteristic part of its container body 221 can be that no magnet 241 is set on both sides, so that when the ultrasonic pickling container is placed on the ultrasonic base 210, both Hall sensors 231 will output a low voltage, which can be represented by (0, 0). For an ultrasonic cleaning container, the characteristic part of its container body 221 can be that no magnet 241 is set on the first side adjacent to the container body 221, and a magnet 241 is set on the second side adjacent to the container body 221. In this way, when the ultrasonic cleaning container is placed on the ultrasonic base 210, the Hall sensor 231 adjacent to the first side of the container body 221 will output a low voltage, and the Hall sensor 231 adjacent to the second side of the container body 221 will output a high voltage, which can be represented by (0, 1). For the ultrasonic atomization container, the characteristic part of the container body 221 can be that the magnet 241 is arranged near the first side of the container body 221, and the magnet 241 is not arranged near the second side of the container body 221. In this way, when the ultrasonic atomization container is placed on the ultrasonic base 210, the Hall sensor 231 near the first side of the container body 221 outputs a high voltage, and the Hall sensor 231 near the second side of the container body 221 outputs a low voltage, which can be represented by (1, 0). In this way, the functional type of the ultrasonic container 220 can be distinguished more conveniently and simply.

[0052] Figure 4 3 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.

[0053] 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 212 and the signal sensing device 230 by signal, and is used to provide a control signal to the ultrasonic generator 212 according to the detection result of the signal sensing device 230, so as to adjust the power of the ultrasonic generator 212, the frequency of the ultrasonic generator 212, and start and stop the ultrasonic generator 212. The controller 300 can be integrated on the main control board of the refrigerator 10, or it can be separately set adjacent to the ultrasonic generator 212. The controller 300 can further be connected to the main control device of the refrigerator 10 by signal, provide the main control device with the operating status of the ultrasonic generator 212, and receive control commands from the main control device.

[0054] 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.

[0055] The timing device 330 may be a timer for accumulating the total processing time of the ultrasonic-assisted processing device 200 so that the ultrasonic-assisted processing device 200 is turned off after the total processing time of the ultrasonic-assisted processing device 200 reaches a preset processing time, thereby avoiding food processing failure due to over-processing.

[0056] Figure 5 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 S108.

[0057] Step S102 : Using the signal sensing device 230 on the ultrasonic base 210 to detect the ultrasonic container 220 .

[0058] Step S104, determining the functional type of the ultrasonic container 220 according to the detection result;

[0059] In this step, it should be noted that a plurality of ultrasonic containers 220 used in conjunction with the ultrasonic base 210 may be provided, and each ultrasonic container 220 has a different functional type so as to achieve different food processing functions.

[0060] Step S106, acquiring ultrasound parameters corresponding to the functional type of the ultrasound container 220;

[0061] Step S108, controlling the ultrasound-assisted processing device 200 to operate according to the ultrasound parameters.

[0062] In the control method of the ultrasonic assisted treatment device 200 of the present invention, since the base is provided with a signal sensing device 230, the type sensing device can automatically identify ultrasonic containers 220 of different functional types, so as to obtain different ultrasonic parameters according to the ultrasonic containers 220 of different functional types, and control the ultrasonic assisted treatment device 200 to operate according to the ultrasonic parameters. Automatic identification of the functional type of the ultrasonic container 220 is achieved, and the ultrasonic parameters can be automatically adjusted according to the functional type, so that the functional use of the ultrasonic assisted treatment device 200 is more extensive.

[0063] In this embodiment, the functions of the ultrasonic container 220 include but are not limited to ultrasonic-assisted pickling, ultrasonic-assisted cleaning, ultrasonic-assisted atomization, etc. For example, ultrasonic-assisted freezing may also be performed.

[0064] The ultrasonic parameters include the frequency of the ultrasonic generator 212. The step of acquiring the ultrasonic parameters corresponding to the functional type of the ultrasonic container 220 may be to acquire the frequency of the ultrasonic transducer 222 corresponding to the functional type of the ultrasonic container 220, and determine the frequency of the ultrasonic generator 212 according to the frequency of the ultrasonic transducer 222. Since the frequencies of the ultrasonic transducers 222 at the bottom of ultrasonic containers 220 of different functional types are different, in order to enable the ultrasonic generator 212 to send a matching driving signal to the ultrasonic transducer 222, the power of the ultrasonic generator 212 should be ensured to be consistent with the frequency of the ultrasonic transducer 222.

[0065] Further, the ultrasonic parameters also include the power of the ultrasonic generator 212. The step of obtaining the ultrasonic parameters corresponding to the functional type of the ultrasonic container 220 also includes: obtaining the power of the ultrasonic generator 212 corresponding to the functional type of the ultrasonic container 220. For example, when the ultrasonic container 220 is used to wash food, the power of the ultrasonic generator 212 is relatively large to increase the washing speed. When the ultrasonic container 220 is used to marinate food, the power of the ultrasonic generator 212 is relatively small to ensure the marinating effect.

[0066] Furthermore, the ultrasonic parameters may also include a target power-on ratio, and the step of obtaining the ultrasonic parameters corresponding to the functional type of the ultrasonic container 220 may further include: obtaining the target power-on ratio corresponding to the functional type of the ultrasonic container 220. The continuous vibration of the ultrasonic transducer 222 may generate a large amount of heat, and the heat may be transferred to the container body 221, which may easily cause the food processing temperature to be too high. By controlling the ultrasonic-assisted processing device 200 to operate according to the target power-on ratio, the ultrasonic-assisted processing device 200 may be cooled in time, thereby preventing the temperature of the container body 221 from being too high.

[0067] Considering that in both cases, when the ultrasonic pickling container 220 is placed on the base and when the ultrasonic container 220 is not placed on the base, the outputs of the two Hall sensors 231 are both low level, that is, (0, 0). Therefore, in order to avoid mistaking the ultrasonic pickling container 220 not being placed on the base for the ultrasonic pickling container 220 being placed on the base, in this embodiment, before the step of using the signal sensing device 230 on the ultrasonic base 210 to detect the ultrasonic container 220, it is also possible to determine whether the ultrasonic container 220 is placed on the ultrasonic base 210. After determining that the ultrasonic container 220 is in place, the ultrasonic container 220 is detected by using the signal sensing device 230 on the ultrasonic base 210.

[0068] Since the preset processing time of different ingredients is different, for example, chicken needs to be processed for 30 minutes, pork needs to be processed for 40 minutes, and beef needs to be processed for 60 minutes. Therefore, in this embodiment, after the step of controlling the ultrasonic assisted processing device 200 to operate according to the ultrasonic parameter cycle, it is also possible to determine whether the total processing time of the ultrasonic assisted processing device 200 reaches the preset processing time, if so, turn off the ultrasonic assisted processing device 200, if not, continue to operate the ultrasonic assisted processing device 200.

[0069] Figure 6 2 is a flow chart of a control method of an ultrasound-assisted treatment device 200 according to an embodiment of the present invention. The control method at least includes the following steps S202 to S220.

[0070] Step S202, determining whether an ultrasound container 220 is placed on the ultrasound base 210, if so, executing step S204.

[0071] Step S204 : using the two Hall sensors 231 on the ultrasonic base 210 to detect the placed ultrasonic container 220 .

[0072] Step S206 , determining whether the detection results of the two Hall sensors 231 are (0, 0), if so, executing step S208 , if not, executing step S210 .

[0073] Step S208, obtaining ultrasonic parameters corresponding to the ultrasonic pickling function, and then executing step S216.

[0074] Step S210, determining whether the detection results of the two Hall sensors 231 are (0, 1), if so, executing step 212, if not, executing step S214.

[0075] Step S212, acquiring ultrasonic parameters corresponding to the ultrasonic cleaning function, and then executing step S216.

[0076] Step S214, obtaining ultrasonic parameters corresponding to the ultrasonic atomization function, and then executing step S216.

[0077] Step S216, controlling the ultrasound-assisted processing device 200 to operate according to the acquired ultrasound parameters.

[0078] Step S218, determining whether the total processing time of the ultrasound-assisted processing device 200 reaches the preset processing time, if so, executing step S220, if not, returning to step S216.

[0079] 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.
