Description

Technical Field

[0001] This invention relates to the field of refrigeration and freezing equipment, and in particular to an ultrasonic processing device and refrigerator for food processing. Background Technology

[0002] Currently, many types of ingredients require pre-treatment before consumption or cooking. Pre-treatment can include washing, marinating, thawing, and soaking to improve flavor. Traditional processing methods suffer from low efficiency and limited effectiveness. While ultrasound-assisted processing exists, its application has not been widely adopted due to the limitations of ultrasound's mechanism. Summary of the Invention

[0003] One objective of the first aspect of this invention is to rationally set the diameter-to-depth ratio of the container and the ultrasonic frequency of the ultrasonic transducer in order to reduce the influence of the container diameter-to-depth ratio on the ultrasonic transducer.

[0004] A further objective of the first aspect of the invention is to transfer the weight of the food to be processed to the side wall of the container, thereby reducing the stress on the bottom wall of the container.

[0005] A second aspect of the present invention is to provide a refrigerator including the above-described ultrasonic processing device.

[0006] In particular, according to a first aspect of the present invention, the present invention provides an ultrasonic processing apparatus for use in a refrigerator, comprising:

[0007] A container having a recessed, upward-opening internal space for holding the processing liquid and the food to be processed; and

[0008] At least one ultrasonic transducer is disposed on the lower surface of the bottom wall of the container and configured to perform controlled ultrasonic vibrations to apply ultrasonic action to the food to be processed.

[0009] The container and the ultrasonic transducer are configured such that the aspect ratio of the container and the ultrasonic frequency of the ultrasonic transducer conform to the following formula:

[0010]

[0011] Where h is the depth of the container, d is the inner diameter of the bottom wall of the container, f is the ultrasonic frequency of the ultrasonic transducer for ultrasonic vibration, and K is a predetermined scaling factor with a value of any value in (0, 0.5).

[0012] Optionally, the K value can be any value in [0.01, 0.5], which further narrows the range of the container diameter-to-depth ratio to improve the uniformity of the container shape.

[0013] Optionally, the ultrasonic transducer is an ultrasonic wafer.

[0014] Optionally, the number of ultrasonic transducers is one, and the ultrasonic transducer is arranged at the center of the lower surface of the bottom wall of the container.

[0015] The number of ultrasonic transducers is three. The three ultrasonic transducers are arranged sequentially or adjacent to each other along the circumference on the lower surface of the bottom wall of the container.

[0016] Optionally, the ultrasonic processing device further includes:

[0017] A shelf, placed inside a container, used to hold the food to be processed;

[0018] The items are supported directly or indirectly on the side walls of the container to transfer the weight of the food to be processed to the side walls of the container.

[0019] Optionally, the distance between the upper surface of the object and the upper surface of the bottom wall of the container is 0.5 mm to 64 mm.

[0020] Optionally, the container is made of stainless steel and has side walls and a bottom wall;

[0021] The sidewall thickness of the container is 0.2mm to 20mm;

[0022] The bottom wall thickness of the container is 0.2mm to 20mm.

[0023] Alternatively, the container may be an upward-opening cylindrical shape.

[0024] Optionally, the treatment solution is a marinating solution, and the food to be treated is food to be marinated; or

[0025] The processing solution is water, and the food to be processed is food to be thawed; or

[0026] The treatment solution is water, and the ingredients to be treated are those that need to be soaked.

[0027] According to a second aspect of the present invention, a refrigerator is provided therein, which is provided with any of the above-described ultrasonic processing devices.

[0028] The ultrasonic processing apparatus of the present invention comprises a container and an ultrasonic transducer configured such that the aspect ratio of the container and the ultrasonic frequency of the ultrasonic transducer are compatible. Users can select the container's diameter-to-depth ratio based on the ultrasonic transducer's ultrasonic frequency, and vice versa. Extensive experiments have confirmed that when the container's diameter-to-depth ratio and the ultrasonic transducer's ultrasonic frequency are set to meet the following conditions... At this time, the overall weight of the processing liquid and the food to be processed has almost no significant impact on the ultrasonic amplitude and ultrasonic frequency of the ultrasonic transducer, which can give full play to the working performance of ultrasonic transducers with different ultrasonic frequencies, and provides a reliable basis for the promotion and application of ultrasonic transducers.

[0029] Furthermore, in the ultrasonic processing apparatus of the present invention, a support is provided inside the container. This support directly or indirectly supports the side wall of the container, transferring the weight of the food to be processed to the side wall. After the weight of the food is transferred to the side wall, the container only bears the weight of the processing liquid. This reduces the stress on the container and minimizes the impact on the ultrasonic amplitude and frequency of the ultrasonic transducer, thus facilitating the full utilization of the ultrasonic transducer's performance.

[0039] Exemplary embodiments of the present disclosure will now be described in more detail 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 implemented 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.

[0040] The present invention first provides a refrigerator 10, Figure 1 This is a schematic diagram of the structure of a refrigerator 10 according to an embodiment of the present invention, with reference to... Figure 1 The refrigerator 10 may include a cabinet 100, and the interior of the cabinet 100 forms one or more storage compartments 110. The storage compartments 110 can be configured as refrigerator compartments, freezer compartments, and variable temperature compartments of the refrigerator 10 according to the cooling temperature. Specifically, the number, function, and layout of the storage compartments 110 can be configured according to requirements.

[0041] The refrigerator 10 may further include an ultrasonic processing device 200, which may be installed inside the storage compartment 110 of the refrigerator 10 or inside the door of the refrigerator 10. The installation method includes, but is not limited to, fixed installation or removable installation.

[0042] Normally, the ultrasonic processing device 200 is installed in the refrigerator compartment of the refrigerator 10. If the refrigerator 10 has a dedicated processing compartment, the ultrasonic processing device 200 can be installed in that processing compartment. In addition, in some special cases, it is also feasible to install the ultrasonic processing device 200 in a variable temperature compartment or a freezer compartment.

[0043] Figure 2 This is a schematic diagram of the structure of an ultrasonic processing device 200 according to an embodiment of the present invention. Figure 3 yes Figure 2 A schematic bottom view of the ultrasonic processing device 200 shown. Figure 4 yes Figure 2 A schematic cross-sectional view of the ultrasonic processing device 200 shown.

[0044] Reference Figures 2 to 4 The ultrasonic processing apparatus 200 may include a container 210 and at least one ultrasonic transducer 220. The container 210 has a recessed, upward-opening internal space for holding a processing liquid and food to be processed. The ultrasonic transducer 220 may be disposed on the lower surface of the bottom wall of the container 210 and configured to perform controlled ultrasonic vibrations to apply ultrasonic action to the food to be processed, thereby utilizing ultrasonic action to improve the processing speed and processing effect of the food.

[0045] In practical applications, when the filling height of the treatment liquid in the container 210 is high, the overall weight of the treatment liquid and the food to be treated is applied to the bottom wall of the container 210, which will cause the ultrasonic amplitude of the ultrasonic transducer 220 to decrease and the ultrasonic frequency to decrease, thereby resulting in a poorer treatment effect on the food to be treated, which is not conducive to the proper application of the ultrasonic transducer 220.

[0046] In this embodiment, the container 210 and the ultrasonic transducer 220 are required to be configured such that the aspect ratio of the container 210 and the ultrasonic frequency of the ultrasonic transducer 220 conform to the following formula:

[0047]

[0048] Where h is the depth of container 210, d is the inner diameter of the bottom wall of container 210, f is the ultrasonic frequency of ultrasonic vibration of ultrasonic transducer 220, and K is a predetermined scaling factor, with K value being any value in (0, 0.5].

[0049] The ultrasonic processing apparatus 200 of the present invention has a container 210 and an ultrasonic transducer 220 configured such that the aspect ratio of the container 210 and the ultrasonic frequency of the ultrasonic transducer 220 are compatible. Users can select the aspect ratio of the container 210 based on the ultrasonic frequency of the ultrasonic transducer 220, and vice versa. Extensive experiments have confirmed that when the aspect ratio of the container 210 and the ultrasonic frequency of the ultrasonic transducer 220 are set to satisfy… At this time, the overall weight of the processing liquid and the food to be processed has almost no significant impact on the ultrasonic amplitude and ultrasonic frequency of the ultrasonic transducer 220, which can give full play to the working performance of the ultrasonic transducer 220 and provide a reliable basis for the promotion and application of the ultrasonic transducer 220.

[0050] It should be noted that since container 210 is used inside refrigerator 10, the depth of container 210 generally does not exceed 320mm, meaning the height of container 210 should not be too high. The ultrasonic frequency of ultrasonic transducer 220 is generally between 20KHz and 100KHz, such as 20KHz, 30KHz, 60KHz, and 100KHz.

[0051] In a preferred embodiment of the present invention, the K value can be further any value in [0.01, 0.5], thereby further narrowing the range of the diameter-to-depth ratio of the container 210 to improve the symmetry of the container 210's shape. It can be understood that when the ultrasonic frequency of the ultrasonic transducer 220 is 20 kHz and the K value is 0.01, the diameter-to-depth ratio of the container 210 reaches its minimum value of 0.2. When the ultrasonic frequency of the ultrasonic transducer 220 is 100 kHz and the K value is 0.5, the diameter-to-depth ratio of the container 210 reaches its maximum value of 50. By reasonably selecting the K value, it is possible to prevent the diameter-to-depth ratio of the container 210 from being too large or too small, resulting in the container 210 having a long and thin shape or a short and thick shape.

[0052] Generally, in actual setup, both the container 210 and the ultrasonic transducer 220 are existing designs. The inner diameter of the bottom wall of the container 210 is fixed. By appropriately selecting the height of the container 210 and the K value, the diameter-to-depth ratio of the container 210 is made to match the ultrasonic frequency of the ultrasonic transducer 220.

[0053] In this embodiment, the ultrasonic transducer 220 is preferably an ultrasonic wafer. The ultrasonic wafer is a thin, circular sheet, occupying little space and easy to install; it only needs to be fixed to the lower surface of the bottom wall of the container 210 by means of adhesive or other methods. The diameter of the ultrasonic wafer should not be too small or too large, generally around 30mm to 40mm. If the diameter of the ultrasonic wafer is too small, the ultrasonic effect will be poor; if the diameter is too large, the operating noise will be high, affecting the user experience.

[0054] Container 210 can be made of stainless steel. Stainless steel containers 210 are corrosion-resistant, easy to clean, not easily damaged, and will not contaminate the food to be processed, making them particularly suitable for holding different types of processing liquids and food to be processed.

[0055] The container 210 in this embodiment has at least a side wall and a bottom wall. The thickness of the side wall of the container 210 can be 0.2mm to 20mm, for example, 0.5mm, 1.0mm, etc., and the thickness of the bottom wall of the container 210 can be 0.2mm to 20mm, for example, 0.3mm, 0.5mm, etc. Relatively speaking, the bottom wall thickness of the container 210 is required to be relatively high, and it should not be too thin or too thick. If the bottom wall thickness of the container 210 is too thin, the container 210 will break at the connection between the bottom wall and the side wall when the ultrasonic transducer 220 is performing continuous ultrasonic vibration, so it is necessary to ensure that the bottom wall of the container 210 has sufficient structural strength. If the bottom wall thickness of the container 210 is too thick, the ultrasonic action applied by the ultrasonic transducer 220 will experience greater loss when penetrating the bottom wall, reducing the working efficiency of the ultrasonic transducer 220.

[0056] It should be noted that the depth of container 210 refers to the vertical distance between the upper surface of the bottom wall of container 210 and the upper edge of the side wall of container 210. The bottom wall shape of container 210 can be various. When the bottom wall of container 210 is circular, the inner diameter of the bottom wall of container 210 is the diameter of the circle; when the bottom wall of container 210 is elliptical, the diameter of the bottom wall of container 210 is the diameter of the minor axis of the ellipse; when the bottom wall of container 210 is rectangular, the diameter of the bottom wall of container 210 is the diameter of the inscribed circle of the rectangle.

[0057] The number and arrangement of the ultrasonic transducers 220 can be configured according to actual conditions. Specifically, for example, when there is one ultrasonic transducer 220, it is usually located at the center of the lower surface of the bottom wall of the container 210. When there are three ultrasonic transducers 220, they are arranged sequentially along the circumference on the lower surface of the bottom wall of the container 210, or they are arranged adjacent to each other at intervals on the lower surface of the bottom wall of the container 210.

[0058] Reference Figure 2 and Figure 3 In an optional embodiment of the present invention, the container 210 is an upward-opening cylindrical shape. Correspondingly, the bottom wall of the container 210 is circular. When three ultrasonic transducers 220 are provided, the three ultrasonic transducers 220 are arranged sequentially along the circumference on the lower surface of the bottom wall of the container 210, with the center of the bottom wall being the center of the circle containing the three ultrasonic transducers 220. This arrangement allows for more uniform stress distribution on the outer periphery of the bottom wall, reducing the likelihood of cracks appearing between the bottom wall and the side walls.

[0059] Reference Figure 5 and Figure 6 In another optional embodiment of the present invention, the container 210 is a box-shaped structure with an upward opening. Correspondingly, the bottom wall of the container 210 is rectangular. When three ultrasonic transducers 220 are provided, the three ultrasonic transducers 220 are arranged adjacent to each other at intervals along the length of the bottom wall on the lower surface of the container 210. This allows the ultrasonic effect to be applied more evenly to the food to be processed, improving the uniformity of the processing.

[0060] Reference Figure 4 The ultrasonic processing device 200 may further include a support 230 disposed inside the container 210 to hold the food to be processed. The support 230 may be directly or indirectly supported by the side wall of the container 210 to transfer the weight of the food to be processed to the side wall of the container 210. It is understood that after the weight of the food to be processed is transferred to the side wall of the container 210, the container 210 only bears the weight of the processing liquid. The stress on the container 210 is reduced, and the impact on the ultrasonic amplitude and frequency of the ultrasonic transducer 220 is minimized, which is beneficial for fully utilizing the working performance of the ultrasonic transducer 220.

[0061] Since the ultrasonic transducer 220 applies ultrasonic action to the food to be processed by releasing ultrasonic waves, when the ultrasonic waves are transmitted in the bottom wall of the container 210, there is internal friction in the bottom wall of the container 210. Some of the sound wave energy will be absorbed by the bottom wall of the container 210 and converted into heat energy, thereby raising the temperature of the bottom wall of the container 210.

[0062] In addition, since the ultrasonic waves need to pass through both the bottom wall of container 210 and the processing liquid during the process of transmitting to the food to be processed, and the characteristic impedance of the two media is different at the interface, the ultrasonic waves will be reflected and a standing wave will be formed, which will cause mutual friction between molecules and make the temperature rise at the interface greater.

[0063] Conventional processing methods typically involve directly immersing the food to be processed in the processing solution. The gap between the lower surface of the food and the upper surface of the bottom wall of container 210 is small, generally 0mm to 0.5mm. The food is in close contact with the upper surface of the bottom wall of container 210. During the processing, the lower surface of the food is easily cooked due to the excessively high temperature of the bottom wall of container 210, requiring frequent start-up and shutdown of the ultrasonic transducer 220, which seriously affects the processing speed and effect of the food.

[0064] In this embodiment, the distance between the upper surface of the object holder 230 and the upper surface of the bottom wall of the container 210 is 0.5mm to 64mm. For example, 4mm, 5mm, 9mm, etc. In this way, the food to be processed can be kept away from the lower surface of the bottom wall of the container 210, and there is more processing liquid between the food to be processed and the lower surface of the bottom wall of the container 210, which can effectively reduce the risk of the lower surface of the food to be processed being cooked, reduce the number of times the ultrasonic transducer 220 is started and stopped, and ensure the processing speed and processing effect of the food to be processed.

[0065] In an optional embodiment of the present invention, the shelf 230 can be a shelf board with multiple through holes evenly arranged on its surface. The size of the through holes and the distance between adjacent through holes can be designed according to the actual size of the food to be processed, ensuring that the food to be processed does not fall out of the through holes. The filling height of the processing liquid should at least exceed the lower surface of the food to be processed. When the ultrasonic transducer 220 performs ultrasonic vibration, it can generate a jet stream. The jet stream passes through the through holes and hits the lower surface of the food to be processed, which can further improve the processing effect of the food to be processed.

[0066] The shelf 230 can transfer the weight of the food to be processed to the side wall of the container 210 in various ways. For example, the side wall of the container 210 is provided with ribs, and the shelf 230 can be placed inside the container 210 with its periphery overlapping the ribs. Alternatively, the side wall of the container 210 forms a necked section, and the shelf 230 can be placed inside the container 210 with its periphery overlapping the surface of the upper end of the necked section. Or, the shelf 230 and the container 210 are an integral structure, with the periphery of the shelf 230 fixedly connected to the side wall of the container 210. Those skilled in the art can easily conceive of other ways to fix the position and height of the shelf 230, so these will not be elaborated upon here.

[0067] The ultrasonic treatment device 200 may also include a top cover, the shape of which may be adapted to the shape of the opening at the upper end of the container 210 so that the top cover can be operably closed or opened.

[0068] In one specific implementation, the ultrasonic treatment device 200 is located inside the cold storage compartment. The treatment solution is a marinating solution, and the food to be treated is food to be marinated, such as meat. The ultrasonic action generated by the ultrasonic transducer 220 applied to the food can improve the marinating speed and effect.

[0069] In another specific implementation, the ultrasonic treatment device 200 is installed inside the cold storage compartment, the treatment liquid is water, and the food to be treated is food to be thawed, such as meat. The ultrasonic action generated by the ultrasonic transducer 220 applied to the food can improve the thawing speed and thawing effect.

[0070] In another specific implementation, the ultrasonic treatment device 200 is installed inside the cold storage compartment. The treatment liquid is water, and the food to be treated is food to be soaked, such as wood ear fungus or dried bean curd. The ultrasonic action generated by the ultrasonic transducer 220 is applied to the food to be soaked, which can improve the soaking speed and soaking effect.

[0071] According to any optional embodiment or a combination of multiple optional embodiments described above, the embodiments of the present invention can achieve the following beneficial effects:

[0072] In the ultrasonic processing apparatus 200 of this embodiment, the container 210 and the ultrasonic transducer 220 are configured such that the aspect ratio of the container 210 and the ultrasonic frequency of the ultrasonic transducer 220 are compatible. Users can select the aspect ratio of the container 210 based on the ultrasonic frequency of the ultrasonic transducer 220, and vice versa. Extensive experiments have confirmed that when the aspect ratio of the container 210 and the ultrasonic frequency of the ultrasonic transducer 220 are set to satisfy… At this time, the overall weight of the processing liquid and the food to be processed has almost no significant impact on the ultrasonic amplitude and ultrasonic frequency of the ultrasonic transducer 220, which can give full play to the working performance of the ultrasonic transducer 220 and provide a reliable basis for the promotion and application of the ultrasonic transducer 220.

[0073] Furthermore, in the ultrasonic processing apparatus 200 of this embodiment, a support member 230 is provided inside the container 210. The support member 230 is directly or indirectly supported by the side wall of the container 210, which can transfer the weight of the food to be processed to the side wall of the container 210. After the weight of the food to be processed is transferred to the side wall of the container 210, the container 210 only bears the weight of the processing liquid. The force on the container 210 is reduced, and the impact on the ultrasonic amplitude and ultrasonic frequency of the ultrasonic transducer 220 is reduced, which is beneficial to fully utilizing the working performance of the ultrasonic transducer 220.
