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.
The present invention first provides a refrigerator 10, fig. 1 is a schematic structural view of the refrigerator 10 according to an embodiment of the present invention, and referring to fig. 1, the refrigerator 10 may include a cabinet 100, one or more storage compartments 110 are formed inside the cabinet 100, and the storage compartments 110 may be configured as a refrigerating compartment, a freezing compartment, and a temperature changing compartment of the refrigerator 10 according to a cooling temperature. Specifically, the number, function, layout, etc. of the storage compartments 110 may be configured according to the need.
The refrigerator 10 may further include an ultrasonic treatment device 200, where the ultrasonic treatment device 200 may be disposed inside the storage compartment 110 of the refrigerator 10, or may be disposed inside a door of the refrigerator 10, where the manner of disposing includes, but is not limited to, a fixed disposition, a removable disposition, and the like.
In general, the ultrasonic processing apparatus 200 is disposed in a refrigerating compartment of the refrigerator 10. If the refrigerator 10 has a dedicated processing compartment, the ultrasonic processing apparatus 200 may be disposed within the processing compartment. In addition, in some special cases, it is also possible to dispose the ultrasonic treatment device 200 in a temperature changing compartment or a freezing compartment.
Fig. 2 is a schematic structural view of an ultrasonic processing apparatus 200 according to an embodiment of the present invention, fig. 3 is a schematic bottom view of the ultrasonic processing apparatus 200 shown in fig. 2, and fig. 4 is a schematic cross-sectional view of the ultrasonic processing apparatus 200 shown in fig. 2.
Referring to fig. 2 to 4, the ultrasonic processing apparatus 200 may include a container 210 and at least one ultrasonic transducer 220, wherein the container 210 has a concave and upwardly open accommodating space for accommodating a processing liquid and food material to be processed. The ultrasonic transducer 220 may be disposed at a lower surface of the bottom wall of the container 210 and configured to controllably perform ultrasonic vibration to apply ultrasonic action to the food items to be processed, thereby improving the processing speed and processing effect of the food items to be processed by the ultrasonic action.
In practical application, 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 results in the reduction of the ultrasonic amplitude and the reduction of the ultrasonic frequency of the ultrasonic transducer 220, and further results in the deterioration of the treatment effect of the food to be treated, which is unfavorable for the reasonable application of the ultrasonic transducer 220.
In the present embodiment, it is required that the container 210 and the ultrasonic transducer 220 are disposed such that the aspect ratio of the container 210 and the ultrasonic frequency of the ultrasonic transducer 220 satisfy the following formula:
where h is the depth of the container 210, d is the inner diameter of the bottom wall of the container 210, f is the ultrasonic frequency at which the ultrasonic transducer 220 is ultrasonically vibrated, K is a predetermined scale factor, and K is any one of (0, 0.5).
The ultrasonic treatment apparatus 200 of the present invention has the container 210 and the ultrasonic transducer 220 configured such that the aspect ratio of the container 210 and the ultrasonic frequency of the ultrasonic transducer 220 coincideThe user may select the ratio of the diameter to depth of the container 210 based on the ultrasonic frequency of the ultrasonic transducer 220, or may select the ultrasonic frequency of the ultrasonic transducer 220 based on the ratio of the diameter to depth of the container 210. It was confirmed through a number of experiments that when the aspect ratio of the container 210 and the ultrasonic frequency of the ultrasonic transducer 220 were set to be satisfied +.>When the ultrasonic transducer 220 is used, the whole weight of the treatment fluid and the food material to be treated hardly has great influence on the ultrasonic amplitude and the ultrasonic frequency of the ultrasonic transducer 220, the working performance of the ultrasonic transducer 220 can be fully exerted, and a reliable basis is provided for popularization and application of the ultrasonic transducer 220.
It should be noted that, since the container 210 is disposed in the refrigerator 10 for use, the depth of the container 210 is generally not more than 320mm, that is, the height of the container 210 is not too high. The ultrasonic frequency of the ultrasonic transducer 220 is typically in the range of 20KHz to 100KHz, such as 20KHz, 30KHz, 60KHz, 100KHz, etc.
In a preferred embodiment of the present invention, the K value may be any one of the values of [0.01,0.5], such that the ratio range of the aspect ratio of the container 210 is further narrowed to enhance the uniformity of the container 210. It will be appreciated that the ratio of the diameter to depth of the container 210 is at a minimum of 0.2 when the ultrasonic frequency of the ultrasonic transducer 220 is 20KHz and the K value is 0.01, and at a maximum of 50 when the ultrasonic frequency of the ultrasonic transducer 220 is 100KHz and the K value is 0.5. By properly selecting the value of K, the container 210 can be prevented from having too large or too small a ratio of diameter to depth, resulting in a container 210 having a slender or stubby shape.
Generally, in the actual setting process, the container 210 and the ultrasonic transducer 220 are both existing, the inner diameter of the bottom wall of the container 210 is fixed, and the diameter-depth ratio of the container 210 is matched with the ultrasonic frequency of the ultrasonic transducer 220 by reasonably intercepting the height of the container 210 and selecting the K value
In this embodiment, the ultrasonic transducer 220 is preferably an ultrasonic wafer. The ultrasonic wafer is in a circular sheet shape, occupies a small space, is simply mounted, and is fixed to the lower surface of the bottom wall of the container 210 only by means of gluing or the like. The diameter of the ultrasonic wafer should not be too small or too large, and is generally about 30mm to 40 mm. Too small a diameter of the ultrasonic wafer can cause poor effect of ultrasonic action, too large a diameter can cause large working noise, and use experience of a user is affected.
The container 210 may be made of stainless steel. The container 210 made of stainless steel is corrosion-resistant, easy to clean, not easy to damage and not polluting the food materials to be treated, and is particularly suitable for containing different kinds of treatment liquids and food materials to be treated.
The container 210 of the present embodiment has at least a side wall and a bottom wall, and the thickness of the side wall of the container 210 may be 0.2mm to 20mm, for example, 0.5mm, 1.0mm, etc., and the thickness of the bottom wall of the container 210 may be 0.2mm to 20mm, for example, 0.3mm, 0.5mm, etc. The bottom wall thickness of the container 210 is relatively high, and is not too thin or too thick. If the bottom wall of the container 210 is too thin, the container 210 is broken at the junction of the bottom wall and the side wall when the ultrasonic transducer 220 continuously vibrates ultrasonically, so that the bottom wall of the container 210 needs to have sufficient structural strength. If the bottom wall of the container 210 is too thick, the ultrasonic action applied by the ultrasonic transducer 220 will have a larger loss when penetrating the bottom wall, and the working efficiency of the ultrasonic transducer 220 will be reduced.
It should be noted that, the depth of the container 210 refers to a vertical distance between an upper surface of a bottom wall of the container 210 and an upper edge of a side wall of the container 210. The bottom wall of the container 210 may have a variety of shapes. When the bottom wall of the container 210 is circular, the bottom wall inner diameter of the container 210 is the diameter of the circle; when the bottom wall of the container 210 is elliptical, the bottom wall diameter of the container 210 is the minor axis diameter of the ellipse; when the bottom wall of the container 210 is rectangular, the bottom wall diameter of the container 210 is the diameter of an inscribed circle of the rectangle.
The number and layout of the ultrasonic transducers 220 may be configured according to the actual situation. Specifically, for example, when the number of ultrasonic transducers 220 is one, the ultrasonic transducers 220 are generally disposed at the center position of the lower surface of the bottom wall of the container 210. When the number of the ultrasonic transducers 220 is three, the three ultrasonic transducers 220 are sequentially arranged in the circumferential direction at the bottom wall lower surface of the container 210 or the three ultrasonic transducers 220 are arranged adjacent to each other at a distance from each other at the bottom wall lower surface of the container 210.
Referring to fig. 2 and 3, in an alternative embodiment of the present invention, the container 210 is in the shape of an upwardly open cylinder. Accordingly, the bottom wall of the container 210 is circular. When three ultrasonic transducers 220 are provided, the three ultrasonic transducers 220 are sequentially arranged on the lower surface of the bottom wall of the container 210 along the circumferential direction, and the center of the bottom wall is the center of the circle where the three ultrasonic transducers 220 are located. By the arrangement mode, the periphery of the bottom wall can be uniformly stressed, and cracks are not easy to occur between the bottom wall and the side wall.
Referring to fig. 5 and 6, in another alternative embodiment of the present invention, the container 210 is in the shape of an upwardly open box. Accordingly, the bottom wall of the container 210 is rectangular. When the ultrasonic transducers 220 are provided in three, the three ultrasonic transducers 220 are provided adjacent to each other at intervals in the length direction of the bottom wall at the bottom surface of the bottom wall of the container 210. Therefore, the ultrasonic effect can be uniformly applied to the food material to be treated, and the uniformity of treatment is improved.
Referring to fig. 4, the ultrasonic processing apparatus 200 may further include a shelf 230, the shelf 230 being disposed inside the container 210 for carrying food to be processed. The shelf member 230 may be directly or indirectly supported to the side wall of the container 210 to transfer the weight of the food material to be processed to the side wall of the container 210. It can be appreciated that after the weight of the food material to be processed is transferred to the sidewall of the container 210, the container 210 only bears the weight of the processing liquid, so that the stress condition of the container 210 is reduced, the influence on the ultrasonic amplitude and the ultrasonic frequency of the ultrasonic transducer 220 is reduced, and the working performance of the ultrasonic transducer 220 is fully exerted.
Since the ultrasonic transducer 220 applies ultrasonic action to the food material to be processed in the form of 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, and part of the ultrasonic energy is absorbed by the bottom wall of the container 210 and converted into heat energy, so that the bottom wall temperature of the container 210 is raised.
In addition, since the ultrasonic wave needs to pass through two mediums of the bottom wall of the container 210 and the treatment liquid in the process of transmitting the ultrasonic wave to the food to be treated, and the characteristic impedance of the two mediums at the interface is different, the ultrasonic wave is reflected to form standing waves, so that the mutual friction between molecules is caused, and the temperature rise value at the interface is larger.
In a conventional treatment manner, the food to be treated is generally soaked in the treatment liquid, the gap between the lower surface of the food to be treated and the upper surface of the bottom wall of the container 210 is smaller, generally 0 mm-0.5 mm, the food to be treated is closely attached to the upper surface of the bottom wall of the container 210, and in the treatment process, the lower surface of the food to be treated is easily cured due to the overhigh temperature of the bottom wall of the container 210, and the ultrasonic transducer 220 needs to be started and stopped frequently, so that the treatment speed and the treatment effect of the food to be treated are seriously affected.
In this embodiment, the distance between the upper surface of the shelf 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 treated can be far away from the lower surface of the bottom wall of the container 210, so that more treatment liquid is contained between the food to be treated and the lower surface of the bottom wall of the container 210, the risk that the lower surface of the food to be treated is cured can be effectively reduced, the start-stop times of the ultrasonic transducer 220 are reduced, and the treatment speed and the treatment effect of the food to be treated are ensured.
In an alternative embodiment of the present invention, the placement object 230 may be a placement board, and a plurality of through holes are uniformly arranged on a board body of the placement board, and the size of the through holes and the distance between adjacent through holes may be designed according to the actual size of the food to be processed, so that the food to be processed does not fall from the through holes. The filling height of the treatment liquid at least exceeds the lower surface of the food to be treated, the ultrasonic transducer 220 can cause a exciting flow when in ultrasonic vibration, and the exciting flow is beaten to the lower surface of the food to be treated through the through hole, so that the treatment effect of the food to be treated can be further improved.
The shelf 230 may transfer the weight of the food material to be processed to the sidewall of the container 210 in various ways, for example, the sidewall of the container 210 is provided with ribs, the shelf 230 is removably placed in the container 210, and its circumference is overlapped on the ribs. Or the sidewall of the container 210 is formed with a necked-down portion, and the shelf member 230 is removably received within the container 210 with its peripheral edge overlapping a mesa at the upper end of the necked-down portion. Or the article 230 and the container 210 are integrated, and the periphery of the article 230 is fixedly connected with the side wall of the container 210. Other ways of achieving a fixed height of the position of the shelf 230 will be fully apparent to those skilled in the art and will not be described in detail herein.
The sonication device 200 may also include a cap that may be shaped to conform to the shape of the opening in the upper end of the vessel 210 so that the cap may be operable to close or open the opening.
In a specific embodiment, the ultrasonic treatment device 200 is disposed inside the refrigerating compartment, the treatment liquid is a pickling liquid, and the food material to be treated is a food material to be pickled, such as meat to be pickled. The ultrasonic action generated by the ultrasonic transducer 220 is applied to the food material to increase the curing speed and curing effect of the food material.
In another specific embodiment, the ultrasonic treatment device 200 is disposed inside the refrigerating compartment, the treatment liquid is water, and the food material to be treated is food material to be thawed, such as meat to be thawed. The ultrasonic action generated by the ultrasonic transducer 220 is applied to the food material to increase the thawing speed and thawing effect of the food material.
