Embodiments of the present utility model first provide a refrigerated chiller 20. The refrigeration and freezing apparatus 20 according to the embodiment of the present utility model should be understood in a broad sense, and may be a refrigeration device having a low-temperature storage function, such as a refrigerator, freezer or freezer. Fig. 1 is a schematic block diagram of a refrigeration and freezer 20 according to one embodiment of the utility model. The refrigeration and freezer 20 can generally include a cabinet 600, at least one storage container 200, and at least one heating module 400.

The interior of the case 600 defines a storage compartment 610. For example, the case 600 may include a liner, and the inner side of the liner may define the storage compartment 610. The storage compartment 610 may be a refrigeration compartment, a freezer compartment, or a temperature change compartment, although any other compartment is possible.

At least one storage container 200 is disposed within the storage compartment 610. The storage container 200 provides storage space for storage, which may be a box or drawer.

Fig. 2 is a view showing an internal configuration of the storage compartment 610 of the refrigerating and freezing apparatus 20 according to an embodiment of the present utility model. Fig. 3 is a view showing an internal configuration of the storage compartment 610 of the refrigerating and freezing apparatus 20 according to an embodiment of the present utility model. Fig. 2 and 3 may illustrate the internal configuration of the storage compartment 610 from different perspectives, respectively.

The storage container 200 has an air-conditioning opening 210 to allow air from outside the storage container 200 to flow into the storage container 200. A gas treatment device for generating a specific component may be provided in the storage compartment 610; or the storage compartment 610 may be in gas flow communication with a gas treatment device disposed outside the storage compartment 610 for generating a specific composition to receive gas generated by the gas treatment device. The air-conditioning opening 210 may be opened on a wall of the storage container 200 and communicate the inner space of the storage container 200 with its external environment, such as the storage compartment 610 or the outer space of the storage compartment 610.

The number of storage containers 200 may be one or more. When there are a plurality of storage containers 200, each storage container 200 is provided with an air-conditioning opening 210, respectively. And each storage container 200 defines a storage space for storing a commodity, respectively. At this time, the plurality of storage containers 200 may provide a plurality of storage spaces, so as to facilitate the sorting and storage of food materials.

At least one heating module 400 is thermally connected to the inner space of the storage container 200 one by one to supply heat to the inner space of the storage container 200. When the number of the storage containers 200 is one or more, the number of the heating modules 400 may be one or more accordingly. The number of heating modules 400 is the same as the number of storage containers 200.

When the heating modules 400 are plural, the plural heating modules 400 are in one-to-one correspondence with the plural storage containers 200 to be thermally connected with the inner spaces of the storage containers 200 one by one, so that each storage container 200 can be independently heated.

When the heating module 400 heats and heats the internal space of the storage container 200, the air-conditioning opening 210 introduces the air in the storage compartment 610 into the internal space of the storage container 200, so that the food material in the storage container 200 can gradually contact with the air introduced into the internal space of the storage container 200 during thawing, thereby achieving air conditioning.

Since the storage container 200 has the air-conditioning opening 210, the air-conditioning opening 210 is used for allowing air from outside the storage container 200 to flow into the storage container 200, and the heating module 400 is thermally connected with the internal space of the storage container 200 to provide heat for the internal space of the storage container 200, when the food material needs to be thawed, the heating module 400 can be utilized to provide heat for the internal space of the storage container 200, and on the other hand, air with specific components can be simultaneously input into the internal space of the storage container 200 to adjust the surrounding environment of the food material in the storage container 200, so that the refrigerating and freezing device 20 of the embodiment has both the air-conditioning function and the thawing function, and the food material can maintain good quality in the thawing process.

The heating module 400 may be an electric heating element and generates heat when energized to heat the inner space of the corresponding storage container 200. When there are a plurality of heating modules 400, each heating module 400 is connected to the power supply in an on-off manner. The power supply can be integrated on the main control board of the refrigerating and freezing device 20, and of course, can also be other types of power supplies which are separately and independently arranged from the main control board.

By enabling each heating module 400 to be respectively connected to the power supply in an on-off manner, each heating module 400 can be independently electrified and generate heat according to the heating requirement of the corresponding storage container 200, and the heating device has the advantages of flexibility, high efficiency and energy consumption saving.

In some alternative embodiments, the storage container 200 and the heating module 400 are each multiple. And the air-conditioning openings 210 of each storage container 200 are respectively arranged in an openable and closable manner. For example, a controllable damper may be provided at the air-conditioning opening 210, which is controllably movably provided to open or close the air-conditioning opening 210, such that the air-conditioning opening 210 is openably and closably provided.

When the storage containers 200 and the heating module 400 are respectively plural, the food materials can be stored in a classified manner, and at this time, the air-conditioning opening 210 of each storage container 200 is respectively configured to be openable and closable, and each storage container 200 can independently perform a thawing function and adjust the internal gas environment during the thawing process.

In some alternative embodiments, the refrigerating and freezing apparatus 20 may further include a plurality of detecting devices 500 disposed in one-to-one correspondence with the plurality of storage containers 200, where each detecting device 500 is configured to detect a storage state of a corresponding storage container 200 to determine whether an article is stored in the storage container 200, so that an operation state of the heating module 400 and an opening and closing state of the air-conditioning opening 210 may be determined according to the storage state of the storage container 200.

The storage status is used to indicate whether or not an item is stored in the storage container 200, for example, the storage status may be identified as "1" when an item is stored in the storage container 200, and the storage status may be identified as "0" when an item is not stored in the storage container 200. In one example, the heating module 400 corresponding to the storage container 200 is turned on and the modified atmosphere opening 210 of the storage container 200 is opened if and only if the items are stored within the storage container 200.

By providing the detection device 500 and detecting the storage states of the corresponding storage containers 200 by using the detection device 500, the working states of the heating module 400 and the opening and closing states of the air-conditioning door can be determined according to the detection result of the detection device 500, so that the automation degree of the independent thawing process of each storage container 200 is improved.

The detection device 500 may be a sensor, e.g., an optical sensor, that determines the storage status of the storage container 200 by detecting the available volume of the storage container 200.

In some alternative embodiments, the detection device 500 is a pressure sensor that is disposed within the storage container 200 and is located at the bottom of the storage container 200. In one example, a shelf may be disposed within the storage container 200 and the detection device 500 may be disposed below the shelf. The items may be stored on the shelf so as to be sensed by the detection device 500.

The pressure sensor is used for detecting the storage state of the storage container 200, has the advantages of simple structure, simple and convenient method, accurate result and the like, and can provide reliable data support for state adjustment of the heating module 400 and the air-conditioning opening 210.

In some alternative embodiments, the walls of the storage compartment 610 are provided with communication ports 612 to allow gas from outside the storage compartment 610 to flow into them. At this time, a gas processing device for generating a gas of a specific composition is provided outside the inter-storage chamber 610 and communicates with the communication port 612 of the inter-storage chamber 610 to input the generated gas into the inter-storage chamber 610.

An air flow passage is connected between the communication port 612 and the air-conditioning opening 210 of each storage container 200. That is, the gas flowing into the inter-storage chamber 610 from the communication port 612 may flow into each storage container 200, respectively.

By providing the communication ports 612 on the walls of the storage compartments 610 and connecting the communication ports 612 with the air-conditioning openings 210 of the respective storage containers 200 by means of the air flow passages, it is possible to avoid arranging the air treatment device in the narrow storage compartment 610, to optimize the volume ratio of the storage compartment 610, and to uniformly receive the specific component gases from outside the storage compartment 610 in the respective storage containers 200.

The communication port 612 may be one or more. In some embodiments, the chamber wall of the storage chamber 610 is further provided with an air outlet 614, and an air flow actuating device 720 may be disposed at the air outlet 614, for promoting air from outside the storage chamber 610 to quickly flow into the storage chamber 610 and flow out after flowing through the storage chamber 610.

The gas treatment device is used for generating a gas of a specific composition, such as oxygen, nitrogen, or the like. The gas treatment device may treat the gas by adsorption reaction, electrochemical reaction or any other mechanism, thereby obtaining a gas of a specific composition.

In some alternative embodiments, the gas treatment device is an oxygen treatment device 300 for generating oxygen. That is, the refrigerating and freezing apparatus 20 may further include an oxygen treatment apparatus 300. The oxygen treatment apparatus 300 is used to consume oxygen and/or generate oxygen through an electrochemical reaction, thereby obtaining oxygen-depleted gas and/or oxygen-enriched gas. For example, the oxygen treatment device 300 may generate oxygen through an electrochemical reaction under an operating voltage, thereby acting as an oxygen supply source for the storage container 200. Of course, in another example, the oxygen treatment device 300 may also consume oxygen through an electrochemical reaction under an operating voltage and deliver an oxygen-depleted gas to the storage container 200 to reduce the oxygen content of the storage container 200.

The position of the oxygen treatment device 300 may be selected according to actual needs, for example, may be disposed inside the case 600, or may be disposed outside the case 600, as long as the communication port 612 is provided to communicate with the storage compartment 610. In one example, the oxygen treatment device 300 is disposed in the casing 600, for example, may be disposed in a foam layer of the casing 600 or in a compressor chamber of the casing 600, and is connected to the communication port 612 of the storage compartment 610 through a pipe.

Fig. 4 is a schematic structural view of an oxygen treatment device 300 of the refrigerating and freezing apparatus 20 according to an embodiment of the present utility model, and fig. 5 is a schematic exploded view of the oxygen treatment device 300 of the refrigerating and freezing apparatus 20 shown in fig. 4. In some alternative embodiments, oxygen treatment device 300 may include a housing 320, a cathode plate 330, and an anode plate 340. Wherein the housing 320 has a lateral opening 321. For example, the housing 320 may have a flat rectangular parallelepiped shape. The lateral opening 321 may be provided on any face of the housing 320, such as a top face, a bottom face, or a side face. In one example, the lateral opening 321 may be disposed on a face of the housing 320 where the area is greatest.

The cathode plate 330 is disposed at the lateral opening 321 to define an electrolysis chamber for containing an electrolyte together with the case 320, and to consume oxygen through an electrochemical reaction under the action of an electrolysis voltage. Under the action of the electrolysis voltage, the oxygen in the air can undergo a reduction reaction at the cathode plate 330, namely O ₂ +2H ₂ O+4e ^- →4OH ^- 。

The anode plate 340 and the cathode plate 330 are disposed in the electrolysis chamber to be spaced apart from each other, and serve to supply reactants to the cathode plate 330 and generate oxygen through an electrochemical reaction. OH generated by cathode plate 330 ^- An oxidation reaction may occur at anode plate 340 and produce oxygen, namely: 4OH ^- →O ₂ +2H ₂ O+4e ^- . The housing 320 may be provided with an exhaust hole 323, that is, the exhaust hole 323 is disposed on the housing 320. The exhaust hole 323 is communicated with the liquid storage cavity and is used for exhausting oxygen generated by the anode plate 340.

The above examples of electrochemical reactions with respect to the cathode plate 330 and the anode plate 340 are merely illustrative, and those skilled in the art should easily change the types of electrochemical reactions or develop the structure of the oxygen treatment device 300 suitable for other types of electrochemical reactions based on the above-described embodiments, and such changes and development should fall within the scope of the present utility model.

323 vent holes are in communication with the communication port 612 to allow oxygen exhausted from the vent holes to flow into the inter-storage chamber 610.

The casing 320 may further be provided with a fluid-supplementing port 322, and the fluid-supplementing port 322 may be communicated with an external fluid source through a pipeline, so that fluid from the external fluid source may flow into the electrolysis chamber to supplement fluid.

In some alternative embodiments, a supply air duct is also defined within the cabinet 600 for delivering a flow of cooling air to the storage compartment 610. The air supply duct communicates with the inner space of the storage compartment 610 through an air supply port. The cooling air flow is used to adjust the temperature of the storage compartment 610 such that the temperature of the storage compartment 610 is reduced or maintained at a low temperature.

The air supply opening is provided with an air door which is controllably and movably arranged to adjust the opening size of the air supply opening, thereby adjusting the flow of the refrigerating air flow flowing through the air supply opening. The air door can shield the air supply outlet, so that the opening size of the air supply outlet is zero; the air door can also not cover the air supply outlet at all, so that the opening of the air supply outlet is in the maximum state.

In some alternative embodiments, the supply air duct also communicates with the interior space of the storage compartment 610 through the return air duct. The flow of refrigerant through the compartment 610 may return from the return air inlet to the supply air duct. An air supply fan may be disposed at the air return opening to facilitate circulation of air flowing through the air supply duct, the air supply opening, the storage compartment 610, and the air return opening in sequence.

With the above structure, the compartment 610 can selectively receive the cooling air flow flowing through the air supply duct according to actual needs, and on this basis, after the thawing of the food in the storage container 200 is completed, the air supply opening can be opened, and the cooling air flow flows into the compartment 610 and then into the storage container 200, so that the thawed food is kept cool and fresh.

In some alternative embodiments, a plurality of storage containers 200 are juxtaposed in a horizontal direction. For example, the plurality of storage containers 200 may be arranged in the lateral direction or the front-rear direction in order, but may be arranged in any other manner in parallel.

When the plurality of storage containers 200 are arranged side by side in the horizontal direction, the plurality of storage containers 200 may uniformly receive the cooling air flow and/or the oxygen of the storage compartment 610, so that the internal atmosphere of each storage container 200 may be uniformly adjusted.
