The at least one first ultrasonic generator 400 is arranged on one side of the container upper cover assembly 200 facing the accommodating cavity 600, and is used for applying ultrasonic waves to the stored food materials in the accommodating cavity 600 and absorbing heat emitted in the process of applying the ultrasonic waves by the at least one first ultrasonic generator 400 through interlayer medium.
When the ultrasonic-assisted processing compartment 100 is used for rapidly freezing the stored food material, the ultrasonic-assisted processing compartment 100 may be disposed in a low-temperature space to cool the stored food material in the low-temperature space, and a user may place the stored food material (e.g., meat, etc.) in the ultrasonic-assisted processing compartment 100 and then automatically or manually initiate a freezing procedure of the refrigerator 700 to start freezing the stored food material. For example, in the air-cooled refrigerator 700, when a user starts a freezing process, the power of a compressor, a fan, and the like of the refrigerator 700 is increased, and the air volume is increased, so that stored food is rapidly cooled. Of course, as known to those skilled in the art, there are other solutions to the freezing technique of the refrigerator 700, and no further description is provided herein in order to avoid obscuring and obscuring the utility model of the present application.
As in the background art, the freezing scheme of the refrigerator with the quick-freezing mode in the prior art only solves the problem of how to quickly freeze, but the meat product still undergoes the crystallization process from outside to inside, and the stability of the temperature of the meat product cannot be guaranteed in the face of large temperature fluctuation, so that the quality of the stored food material is affected.
In order to overcome the above-mentioned drawbacks of the prior art, the ultrasonic-assisted treatment chamber 100 of the present invention defines a separate receiving chamber 600 for receiving the stored food material by providing the container cover assembly 200 and the container base assembly 300; through set up at least one first ultrasonic generator 400 towards one side of holding chamber 600 at container upper cover assembly 200, to holding the storage food material in chamber 600 and exert the ultrasonic wave, can utilize the supplementary freezing process that accomplishes of ultrasonic action. In addition, the ultrasonic auxiliary treatment chamber 100 of the present invention is provided with the first interlayer cavity 230 inside the container upper cover assembly 200, and the first interlayer cavity 230 is filled with the interlayer medium, on one hand, after the interlayer medium absorbs the cold energy in the low temperature environment, the temperature change rate of the interlayer medium is smaller than the temperature change rate of the container upper cover assembly 200 and the storage food material located below the container upper cover assembly 200, so that the interlayer medium can ensure that the temperature change rate of the container upper cover assembly 200 keeps smooth and stable change as much as possible, thereby ensuring that the storage food material is cooled uniformly and the temperature change rate is stable, thereby preventing the internal texture of the storage food material from being damaged, and improving the quality of the storage food material; on the other hand, because interlayer medium still simultaneously with first ultrasonic generator 400 indirect contact, consequently can absorb first ultrasonic generator 400 and apply the heat that the ultrasonic wave in-process gived off, can not influence the freezing efficiency of whole supplementary freezing device of supersound to an environment that can realize storing the quick freezing of edible material has been provided, the refrigeration quality of storing edible material has been guaranteed.
In addition, the ultrasonic-assisted treatment chamber 100 of the present invention introduces an ultrasonic-assisted freezing technology, which can rapidly freeze the stored food materials, i.e., can enhance heat transfer during the freezing process of the stored food materials. The physical effect (cavitation effect) of ultrasonic wave not only can promote the formation of crystal nucleus at the storage food material in-process that freezes, moreover because the microbubble that cavitation effect produced can regard as new crystal nucleus, change the nucleation temperature of the inside moisture of storage food material, reduce the storage food material supercooling degree, promote the quick nucleation of ice crystal, consequently, the ultrasonic wave can accelerate the inside heat transfer of storage food material, makes the storage food material cooling rate accelerate. Meanwhile, the ultrasonic waves have a crushing effect on larger ice crystals to form small and uniform ice crystals, so that damage to cells is reduced, and freshness of stored food materials is guaranteed.
When the ultrasonic-assisted processing chamber 100 is used for rapidly pickling the stored food, the ultrasonic-assisted processing chamber 100 may be disposed in the low-temperature space to cool the stored food in the low-temperature space, and the user may place the stored food (e.g., the stored food such as meat) in the ultrasonic-assisted processing chamber 100 and then automatically or manually start the pickling process of the refrigerator 700 to start pickling the stored food. As described in the background section, currently, the pickling of the storage food materials by consumers is usually performed by directly placing the pickled materials and the storage food materials in a refrigerating chamber after stirring, and the required pickling time is long. According to the ultrasonic auxiliary treatment chamber 100, at least one first ultrasonic generator 400 is arranged on one side, facing the accommodating cavity 600, of the container upper cover assembly 200, and ultrasonic waves emitted by the first ultrasonic generator 400 act on the stored food materials in the accommodating cavity to push particles in the stored food materials to vibrate in a reciprocating manner, so that the speed of the marinating materials entering the stored food materials is increased, the rapid marinating is realized, and the overlong marinating time is not needed.
As shown in fig. 3, in some embodiments, the container upper cover assembly 200 includes a top cover 210 and a top cover base 220, wherein the top cover 210 is sealingly fastened to the top cover base 220 to form a first barrier cavity 230 with the top cover base 220.

Specifically, in order to facilitate a user or a maintenance worker to fill the interlayer medium into the second interlayer cavity 330, the inner container 310 or the container shell 320 may be provided with a fluid infusion port (not shown in the figure), and after fluid infusion is finished, the fluid infusion port may be sealed by a plug; in addition, in order to ensure the sealing performance between the inner container 310 and the container housing 320, the inner container 310 and the container housing 320 may be directly sealed, for example, by adding a sealing strip, performing a sealing process, and the like.
As shown in fig. 4, the surface of the barrier medium within the second barrier cavity at least exceeds the bottom end of the liner so that the barrier medium can be used to cool the container base assembly 300 and buffer the freezing rate of the stored food material. In particular, the interlayer medium may be a cold storage agent having a large specific heat capacity, such as a cold storage gel or the like, preferably a solution or semi-solidified medium. The ultrasonic auxiliary treatment chamber 100 of the utility model adopts the liner 310 and the container shell 320 to seal and define the second interlayer cavity 330, and the interlayer medium is filled in the second interlayer cavity 330, so that the interlayer medium is arranged below the containing cavity and in the left and right directions, and the characteristic that the temperature change rate of the interlayer medium is small after the interlayer medium absorbs cold energy in a low-temperature environment is utilized, the temperature change rate of the container lower cover assembly 300 can be ensured to be kept to be changed smoothly and stably as far as possible, the stability of a temperature field in the containing cavity 600 is further ensured, the storage food materials are ensured to be cooled uniformly and stably, the internal texture of the storage food materials is prevented from being damaged, and the quality of the storage food materials is further improved.
In some embodiments, the barrier medium is selected such that its solidification temperature is between-40 ℃ and 0 ℃, e.g., -40 ℃, or-20 ℃, or 0 ℃, and the like, and the barrier medium may be selected to have a specific heat capacity between 1KJ/(kg · K) and 5KJ/(kg · K), e.g., 1KJ/(kg · K), 3KJ/(kg · K), or 5KJ/(kg · K), and the like. By using a barrier medium having a relatively large specific heat capacity, the rate of change of temperature of the container top assembly 200 and the container base assembly 300 is reduced when the same unit of heat (or cold) is absorbed. Thus, after the user starts the freezing process, the temperature change of the container upper cover assembly 200 and the container base assembly 300 is relatively slow, so that the temperature field change of the accommodating cavity 600 tends to be stable, the stored food materials in the accommodating cavity 600 are ensured to be uniformly cooled, the temperature change rate is stable, the internal texture of the stored food materials is prevented from being damaged due to too fast temperature reduction or instability, and the quality of the stored food materials is improved; when the freezing program is abnormal or interrupted, the specific heat capacity of the interlayer medium is large, so that the temperature change rate of the low-temperature space can be buffered no matter the temperature of the low-temperature space rises or falls, the internal texture of a frozen object is prevented from being damaged, and the quality of stored food materials is improved; in addition, the interlayer medium should be selected in consideration of the properties of danger, flammability, non-toxicity, etc., so as to satisfy the use environment of the refrigerator 700.

Specifically, the number of the second ultrasonic generators 500 may be plural, and a plurality of the second ultrasonic generators 500 may be uniformly arranged on a side of the bottom of the container base assembly 300 away from the accommodating chamber 600, and the specific specification and number thereof may be set according to actual conditions.
In some embodiments, at least one second ultrasonic generator 500 is affixed to the bottom of the container base assembly 300, and the at least one second ultrasonic generator 500 is disposed at the center of the container base assembly 300. In addition, because at least one second ultrasonic generator 500 laminating sets up in the bottom of container base assembly 300, the interlayer medium can indirectly contact with second ultrasonic generator 500, therefore the interlayer medium can also absorb the heat that first ultrasonic generator 400 during operation produced, has the heat dissipation effect to first ultrasonic generator 400, guarantees the reliability of first ultrasonic generator 400 work. The ultrasonic auxiliary treatment chamber 100 in this embodiment employs an interlayer medium disposed between the container base assembly 300 and the second ultrasonic generator 500, which not only ensures that the temperature change rate of the container base assembly 300 keeps changing smoothly and stably, and ensures that the stored food material is cooled uniformly, but also ensures that the interlayer medium has a property of large specific heat capacity, absorbs the heat of the second ultrasonic generator 500, and ensures the reliability of the second ultrasonic generator 500.
In some embodiments, the first ultrasonic generator 400 and the second ultrasonic generator 500 are both ultrasonic vibrators or ultrasonic wafers. Specifically, the number of the first ultrasonic generators 400 may be plural, and the plural first ultrasonic generators 400 may be one of ultrasonic vibrators or ultrasonic wafers; the number of the second ultrasonic generators 500 may be plural, and the plural second ultrasonic generators 500 may be one of ultrasonic vibrators or ultrasonic wafers.
In some specific embodiments, the ultrasonic signals generated by the first ultrasonic generator 400 and the second ultrasonic generator 500 each have an acoustic intensity of 0.05W/cm2～2W/cm2E.g. 0.05W/cm2、1W/cm2Or 2W/cm2And the like.
