The invention provides a refrigerator 1, which generally comprises a refrigerator body 10, wherein the refrigerator body 10 comprises an outer shell and a storage liner. The shell wraps the storage liner, and a space between the shell and the storage liner is filled with a heat-insulating material (forming a foaming layer) so as to reduce the outward heat dissipation of the storage liner.
The number of the storage inner containers can be multiple, each storage inner container can define a storage space 110, the multiple storage spaces 110 can be configured into a refrigerating chamber, a freezing chamber, a temperature changing chamber and the like, and the number and the functions of the specific storage spaces 110 can be configured according to the preset requirements.
In some embodiments, one of the storage containers may be further specifically configured as a low-temperature space 120, and the low-temperature space 120 may serve as a quick-freezing compartment of the refrigerator 1 to meet the requirement of a user for quick-freezing food.
In some embodiments, the refrigerator 1 may further comprise an ultrasound-assisted treatment device, which may be arranged within the cryogen space 120 to accelerate the freezing rate and/or curing rate of food material stored within the cryogen space 120.
Referring to fig. 1 and 4, in particular, the ultrasonically assisted treatment device may include a container and an ultrasonic generator 240.
A container may be disposed in the low temperature space 120 for containing food materials. For example, the container may be a drawer 210 or a tray 250 having a storage function, and the user may quickly freeze food (meat, etc.) by placing the food in the drawer 210 or on the tray 250.
An ultrasonic generator 240 may be provided at the periphery of the container, and the ultrasonic generator 240 may be controlled to generate ultrasonic waves, at least a portion of which may be applied to the food material to cause the food material to freeze.
That is, the supplementary processing apparatus of supersound of this embodiment has introduced the supplementary freezing technique of ultrasonic wave, and the ultrasonic wave technique can freeze the edible material fast, can be in the freezing in-process intensive heat transfer of edible material. The formation of crystal nucleus is not only promoted at edible material freezing in-process to the physical effect (cavitation effect) of ultrasonic wave, moreover because the microbubble that cavitation effect produced can regard as new crystal nucleus, changes the nucleation temperature of eating the inside moisture of material, reduces and eats the material super-cooled rate, promotes the quick nucleation of ice crystal, consequently, the ultrasonic wave can accelerate the inside heat transfer of eating the material, makes edible 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 food materials is guaranteed.
For example, the temperature range of the low-temperature space can be adjusted to be between-40 ℃ and 0 ℃ (the specific temperature range can be adjusted as required), the ultrasonic auxiliary treatment device is arranged in the low-temperature space, food materials are crystallized under the action of ultrasonic waves, the cavity effect of the ultrasonic waves can promote the formation of crystal nuclei, accelerate the internal heat transfer, improve the cooling speed, and also can break larger ice crystals to form small and uniform ice crystals, so that the damage to cells is reduced, and the freezing storage quality of food is greatly improved. Namely, the ultrasonic auxiliary processing device is used as an auxiliary freezing device to accelerate the freezing rate of the food material.
For another example, the temperature range of the low-temperature space may be adjusted to 0 ℃ or higher, and the low-temperature space is used for storing fresh fruits and vegetables or food materials stored for a short time. The inventors have further realized that: when the temperature of the low-temperature space is set to be above 0 ℃, the ultrasonic generator 240 can also accelerate the curing rate of the food material to be cured (the food material with the curing material already coated on the surface or immersed in the curing material), that is, the ultrasonic waves generated by the ultrasonic generator 240 have a promoting effect on the curing rate of the food material to be cured. Namely, the ultrasonic auxiliary processing device is used as an auxiliary curing device to accelerate the curing speed of the food material.
It should be noted that the above example is only for clearly describing the working principle of the ultrasonic generator 240 in the present embodiment, and the freezing process and the curing process are not cut apart according to the temperature environment of the ultrasonic auxiliary processing device, and a person skilled in the art should clearly understand that the curing process is performed while the food material is frozen.
In some specific embodiments, the sound intensity of the ultrasonic signal generated by the ultrasonic generator 240 can be set to be at 0.05W/cm 2 To 2W/cm 2 E.g. 0.05W/cm 2 、1W/cm 2 Or 2W/cm 2 Etc. to meet refrigeration requirements.
An interlayer cavity 212 is formed between the container and the ultrasonic generator 240, and an interlayer medium is filled in the interlayer cavity 212, and can be used for cooling the ultrasonic generator 240 and buffering the freezing rate of the food material. The interlayer medium can be a cold storage agent with large specific heat capacity, such as cold storage gel and the like, and is preferably a solution or semi-solidified medium.
Because the interlayer cavity 212 is arranged between the container and the ultrasonic generator 240, and the interlayer medium can be directly or indirectly connected with the ultrasonic generator 240 and the container at the same time, 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 that of the container and the food materials on the container, so that the interlayer medium can ensure that the temperature change rate of the container keeps smooth and stable change as much as possible, further ensure that the food materials are uniformly cooled and have stable temperature change rate, further avoid the internal texture of the food materials from being damaged, and improve the quality of the food materials; on the other hand, because the interlayer medium is also indirectly contacted with the ultrasonic generator 240, the interlayer medium can also absorb heat generated when the ultrasonic generator 240 works, so that the interlayer medium has a heat dissipation effect on the ultrasonic generator 240, and the working reliability of the ultrasonic generator 240 is ensured.
In some embodiments, the interlayer medium may be selected to have a freezing temperature of between-40 ℃ and 0 ℃, such as-40 ℃, 20 ℃, or 0 ℃, and the interlayer medium may be selected to have a specific heat capacity of between 1 KJ/(kg · K), such as 1 KJ/(kg · K), 3 KJ/(kg · K), or 5 KJ/(kg · K). In addition, the interlayer medium should be selected in consideration of the properties of danger, flammability, non-toxicity and the like so as to satisfy the use environment of the refrigerator 1.
In some embodiments, when the container is a flat tray 250, the compartment 212 may be formed above or below the tray 250.
Since the compartment cavity 212 is located between the container and the ultrasonic generator 240, when the compartment cavity 212 is located above the tray 250, the ultrasonic generator 240 may be disposed above the compartment cavity 212 to release ultrasonic waves from top to bottom to the food material on the tray 250 to promote freezing of the food material.
Referring to fig. 4 to 6, similarly, when the interlayer cavity 212 is located below the tray 250, the ultrasonic generator 240 may be disposed below the interlayer cavity 212 to release ultrasonic waves from bottom to top to the food material on the tray 250 to promote the food material to freeze. Compared with the arrangement mode, the ultrasonic generator 240 can avoid food materials when being arranged below the interlayer cavity 212, so that the bearing area of the container is increased, and the arrangement is more reasonable.
Referring to fig. 1-3, in other embodiments, when the container is a drawer 210, the compartment cavity 212 may form the interior or exterior of the drawer 210. As can be seen from the above, when the interlayer cavity 212 is formed inside the drawer 210, the ultrasonic generator 240 is located inside the drawer 210; when the compartment cavity 212 is formed on the exterior of the drawer 210, the sonotrode 240 is located on the exterior of the drawer 210.
In addition, when the container is a drawer 210, the compartment cavity 212 may be formed on a panel on either side of the drawer 210, such as a front panel, a side panel (as shown in FIG. 2), a bottom panel (as shown in FIG. 3), or a back panel of the drawer 210.
In summary, in the present embodiment, whether the container is the drawer 210 or the tray 250, the interlayer cavity 212 may be disposed at any position between the container and the ultrasonic generator 240 to achieve the above technical effects, which will not be described herein.
As described in the background section, in the refrigerator with quick-freezing function in the prior art, because the ultrasonic wave generating device has a large power during operation and the heat dissipation effect inside the refrigerator is not good, the ultrasonic wave generating device may fail due to untimely heat dissipation, which affects the quick-freezing efficiency.
In order to overcome the defects in the prior art, the ultrasonic auxiliary processing device in this embodiment employs an interlayer medium disposed between the container and the ultrasonic generator 240, which not only can ensure that the temperature change rate of the container keeps changing smoothly and stably, and ensure that the food material is cooled uniformly, but also can absorb the heat of the ultrasonic generator 240 by using the property that the interlayer medium has a large specific heat capacity, and ensure the reliability of the operation of the ultrasonic generator 240.
In addition, because the container can be the tray 250 or the drawer 210, and the position of the interlayer cavity 212 is flexible, the technical effect can be achieved as long as the interlayer cavity 212 is arranged between the container and the ultrasonic generator 240, and the container has strong practicability.
Referring to fig. 1-6, in some embodiments, the ultrasonically assisted treatment device may further comprise a barrier formation 230. The barrier-forming member 230 caps at least a portion of the containers to form a barrier cavity 212 between the containers.
In this embodiment, the partition forming member 230 may be recessed inwardly to form the reservoir, and the partition forming member 230 may be snapped over the container to cooperate with the container to form the partition cavity 212. In order to facilitate filling of interlayer media by users or maintenance personnel, a fluid infusion port (not shown in the figure) can be formed in the interlayer forming member 230, and the fluid infusion port can be sealed by a plug after fluid infusion is finished.
In order to ensure the sealing performance between the barrier layer forming member 230 and the container, the barrier layer forming member 230 and the container may be directly sealed, for example, by adding a sealing strip, performing a sealing process, and the like.
As can be seen from the foregoing, since the interlayer cavity 212 is formed between the container and the ultrasonic generator 240, the ultrasonic generator 240 is disposed on a side of the interlayer forming member 230 away from the container, so that the interlayer medium filled in the interlayer cavity 212 can not only smoothly and stably dissipate heat to the food material, but also absorb heat generated by the ultrasonic generator 240 during operation.
Further, in order to increase the carrying area of the container, the partition forming member 230 may be located below the container, and no longer occupy the space above the container, avoiding the food material.
Referring to fig. 1 to 6, in some embodiments, the container may further include a carrier plate 220, the carrier plate 220 is opposite to the spacer forming member 230 and has a plurality of protrusions 222 protruding toward the spacer forming member 230, at least a section of the protrusions 222 is immersed in the spacer medium to increase a contact area between the carrier plate 220 and the spacer medium.
In this embodiment, when the container is a drawer 210, the carrier plate 220 can serve as a bottom plate of the drawer 210, and the carrier plate 220 and the partition forming member 230 form the partition cavity 212. Because the extension 222 of the bearing plate 220 protrudes towards the interlayer forming piece 230, a recess is formed on one side of the bearing plate 220 departing from the interlayer forming piece 230 by the extension 222, the recess can be used for preventing food materials, and because the extension 222 is immersed into the interlayer medium in a subsection manner, the heat exchange area between the food materials and the container is increased, the contact area between the bearing plate 220 and the interlayer medium can be increased, and the heat exchange is optimized.
In some embodiments, the ratio of the volume of the barrier medium to the volume of the barrier cavity 212 may also be set to be between 1/5 and 4/5, such as 1/5, 2/5, or 4/5, etc. By the limitation, not only can the interlayer medium not overflow due to overfilling be ensured, and the extension part 222 can be immersed in the interlayer medium, but also the stability of heat transfer can be ensured.
In some embodiments, the number of the ultrasonic generators 240 may be plural, and the plural ultrasonic generators 240 may be one of ultrasonic vibrators or ultrasonic wafers. A plurality of ultrasonic generators 240 may be uniformly arranged on the side of the partition forming member 230 facing away from the container, and the specific specification and number thereof may be set according to actual conditions.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
