In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Fig. 1 is a schematic block diagram of a refrigeration and freezer 10 according to one embodiment of the utility model. Fig. 2 is a partial enlarged view at a in fig. 1. The refrigerating and freezing device 10 according to the embodiment of the present utility model may be a refrigerator, or may be a refrigerator, a freezer or a refrigerating apparatus having a low-temperature storage function, for example.

The refrigeration and freezer 10 of embodiments of the present utility model can generally include a liner 150 and an air path junction 900.

The interior of the liner 150 defines a storage compartment 152. The storage compartment 152 may be a refrigerated compartment, a chilled compartment, or a variable temperature compartment, although it may be a sub-cooled compartment or any other compartment. In a preferred example, the storage compartment 152 of the present embodiment is a temperature change compartment or a freezer compartment.

The air path joint 900 is fixed on the liner 150, and has at least one first port 910 communicating with the storage compartment 152 and a second port 920 communicating with the outside of the liner 150. Fig. 3 is a schematic structural view of the air path joint 900 of the refrigerating and freezing apparatus 10 shown in fig. 1. The second port 920 communicates with the first port 910 to allow the storage compartment 152 to be in airflow communication with its external environment. When the number of the first interfaces 910 is plural, the second interfaces 920 communicate with each of the first interfaces 910.

Fig. 4 is a schematic assembly structure diagram of the liner 150 and the air path joint 900 of the refrigeration and freezer 10 shown in fig. 1. Fig. 5 is a partial enlarged view at B in fig. 4. By fixedly assembling the air path joint 900 on the liner 150, and making the air path joint 900 define a first interface 910 communicating with the storage compartment 152 and a second interface 920 communicating with the outside of the liner 150, air from the outside of the liner 150 can sequentially flow through the second interface 920 and the first interface 910 into the storage compartment 152, which is equivalent to breaking the air flow barrier between the storage compartment 152 and its external environment, so that the storage compartment 152 of the refrigeration and freezing apparatus 10 can receive air from its external environment to regulate the internal atmosphere.

The second port 920 may be used to communicate with the air conditioning line 440 disposed outside the liner 150 to direct the gases flowing through the air conditioning line 440 to the first port 910 and to allow the gases to enter the storage compartment 152. Of course, the gas in the storage compartment 152 may also flow through the first port 910 and the second port 920 sequentially to the outside of the liner 150, so as to flow out of the storage compartment 152.

In some alternative embodiments, the refrigeration and chiller 10 may further include a foam layer and an air conditioning circuit 440. Wherein the foaming layer is formed at the outer side of the inner container 150. For example, the back, top, bottom and/or sides of the liner 150 may be provided with a foam layer, respectively.

The air-conditioning pipeline 440 is pre-buried in the foaming layer and is communicated with the second interface 920 to convey air to the second interface 920. The pre-embedding of the air conditioning line 440 in the foam layer means that the air conditioning line 440 is pre-positioned in the foam layer prior to the formation of the foam layer, and is not installed after the formation of the foam layer. The air conditioning line 440 may be disposed at any location of the foam layer, for example, may be disposed on the back of the liner 150, or may be disposed on the top, bottom, and/or sides of the liner 150. For a french refrigerator or a T-type refrigerator, in one example, the air conditioning line 440 may be disposed in a gap between the upper liner 150 and the lower liner 150.

By embedding the air-conditioning pipeline 440 in the foaming layer and enabling the air-conditioning pipeline 440 to communicate with the second interface 920, the above scheme of the embodiment constructs a hidden air-path communication structure to allow the storage compartment 152 to exchange air with the external environment thereof, which is beneficial to reducing or avoiding the air-path communication structure from occupying the storage area of the refrigeration and freezing device 10, because the air-conditioning pipeline 440 is not exposed to the storage area.

The air conditioning line 440 may be used to deliver any gas, such as oxygen, nitrogen, etc., to condition the atmosphere of the storage compartment 152. In one example, the modified atmosphere line 440 is configured to deliver oxygen to the storage compartment 152 such that the interior space of the storage compartment 152 creates a high oxygen, fresh-keeping atmosphere. At this time, the end of the air conditioning pipeline 440 away from the second port 920 may be connected to an oxygen supply source, so as to deliver oxygen provided by the oxygen supply source to the storage compartment 152,

Since the air conditioning duct 440 may extend to any location of the refrigerator-freezer 10, for example, may extend to another compartment 152 spaced from the compartment 152, or may extend to a compressor compartment, or may extend into an air duct, and may of course extend to a portion of the foam layer, in one example, an oxygen supply may be disposed in a substantially spatially rich region within the refrigerator-freezer 10 and the air conditioning duct 440 may extend to the oxygen supply to effect the connection, without the oxygen supply being disposed within the compartment 152, which may increase the flexibility of the location of the oxygen supply within the refrigerator-freezer 10.

It should be noted that, in one example, the number of the air path connectors 900 may be one or more. When the gas path joint 900 is provided in plurality, a plurality of storage containers 600 may be provided in the storage compartment 152, and the gas path joint 900 may be in one-to-one communication with the storage containers 600 through the respective second interfaces 920 to deliver gas to the respective storage containers 600. In a further example, the first interface 910 of the gas circuit interface 900 may communicate with the same oxygen supply or may communicate with different oxygen supplies to independently regulate the atmosphere within each storage container 600.

In some alternative embodiments, bladder 150 is provided with a fitting port 154. The air passage engaging member 900 also has a recess 940 communicating with the fitting port 154 for disposing the first port 910, and a faceplate 930 extending radially outwardly from the peripheral wall of the recess 940. The panel 930 is attached to the outer surface or the inner surface of the liner 150 to achieve fixation, and the air path joint 900 seals the fitting port 154.

The peripheral wall of recess 940 may extend from the bottom wall edge of recess 940 towards storage compartment 152. In one example, the peripheral wall of recess 940 is hollow cylindrical; panel 930 is formed extending radially outwardly from the open edge of recess 940; and the panel 930 is attached to the outer surface of the liner 150 to achieve fixation.

When the assembly port 154 is formed on the inner container 150 and the air path joint 900 defines the panel 930 to be attached to the outer surface or the inner surface of the inner container 150 to achieve fixation, the storage compartment 152 can only communicate with the external environment through the first interface 910 and the second interface 920. By adopting the scheme of the embodiment, the air leakage problem is not introduced when the air flow barrier between the storage compartment 152 and the external environment is broken, so that the air tightness of the storage compartment 152 is kept when the air exchange is carried out between the storage compartment 152 and the external environment, and the air conditioning effect is ensured.

Defining an interior space in which the first port 910 is disposed with the recess 940 may reduce or avoid collision or contact of the first port 910 with an external object. In one example, the opening edge of dimple 940 is in the same plane as the inner surface of liner 150. Under the protection of recess 940, first interface 910 has high structural stability and air flow smoothness.

In some alternative embodiments, the first interface 910 and the second interface 920 are hollow cylindrical interfaces, respectively. The first port 910 is disposed in the recess 940 and faces the storage compartment 152 to communicate with the storage compartment 152 through the fitting port 154. A second port 920 extends through the bottom wall of recess 940. To communicate with the first port 910 and to face the outside of the liner 150 to connect with the pipeline.

With the above structure, the first connector 910 and the second connector 920 may be respectively nested with the pipeline to achieve plugging. For example, the first port 910 may be connected to an internal conduit 460 disposed within the storage compartment 152, and the second port 920 may be connected to an air conditioning conduit 440 disposed outside of the liner 150, so as to directionally receive gases from the air conditioning conduit 440 and directionally deliver those gases to a particular area of the storage compartment 152.

The second port 920 may be interconnected with the air conditioning line 440 in advance prior to the formation of the foam layer. The first port 910 may also be pre-connected to the internal conduit 460 within the storage compartment 152. Of course, in another example, the first interface 910 may interconnect with the internal piping 460 within the storage compartment 152 after the foam layer is formed.

In some alternative embodiments, the first interface 910 and the second interface 920 may be directly connected, for example, in an end-to-end manner. In other alternative embodiments, the air circuit engagement member 900 also has a communication tube segment 950 that extends at one end to the bottom wall of the recess 940 and communicates with the second port 920, and at the other end extends to the interior of the recess 940 and communicates with the first port 910.

That is, a communication tube segment 950 is connected between the first port 910 and the second port 920, which defines an airflow channel between the first port 910 and the second port 920. The first connector 910 and the second connector 920 are communicated by the communicating pipe 950, and a plurality of first connectors 910 can extend from different positions of the communicating pipe 950.

In some alternative embodiments, gas circuit interface 900 also has orthogonal first plate-like ribs 961 and second plate-like ribs 962 secured within recess 940 to provide support to first interface 910. The first interface 910 may be directly or indirectly secured to the first plate-like rib 961 and the second plate-like rib 962.

The outer wall of the communication pipe section 950 is fixed by being injection molded integrally with the first plate-like rib 961 and the second plate-like rib 962. The first port 910 is secured by being injection molded integrally with the communication tube segment 950. The second port 920 is fixed by being injection molded integrally with the bottom wall of the recess 940. In a further example, the entire gas circuit interface 900 may be manufactured by an injection molding process.

With the above structure, the internal structure assembly process of the air passage joint 900 can be omitted. In the process of assembling the air path joint 900 to the liner 150, only the air path joint 900 needs to be fixed to the liner 150, and the assembly can be completed through one step operation, which is beneficial to reducing the labor cost of the manufacturing process of the refrigeration and freezing device 10.

In some alternative embodiments, the liner 150 is also provided with a first screw hole 156. The panel 930 is correspondingly provided with a second screw hole 931 opposite to the first screw hole 156, so as to be fixed on the outer surface of the inner container 150 through screwing, and the panel 930 of the air path joint 900 is firmly attached to the outer surface of the inner container 150.

The side and bottom of the panel 930 may be connected with a hemming bending structure 932, and the hemming bending structure 932 is used to position the inner container 150 and limit the position, so that the installation process is fast and convenient.

In some alternative embodiments, the refrigeration and freezer 10 can further include at least one storage container 600 disposed within the storage compartment 152, the interior of the storage container 600 defining a storage space. The wall of the storage container 600 is provided with a vent 610 communicating with the storage space. The vents 610 are in one-to-one communication with the first ports 910. The vent 610 may be an opening in the wall of the container 600.

In one example, the storage container 600 and the first interface 910 are each a plurality. When there are a plurality of storage containers 600, each storage container 600 defines a separate storage space inside. A vent 610 is formed in the wall of each storage container 600 to communicate with the storage space. Each of the first ports 910 is respectively in communication with one of the vents 610.

When a plurality of storage containers 600 are arranged in the storage compartment 152 and the first interfaces 910 of the air path connectors 900 are provided in plurality, air from outside the liner 150 can enter each storage container 600 through each first interface 910, so that a plurality of independent spaces with fresh-keeping function are formed in the storage compartment 152 at the same time, which is convenient for sorting and storing the articles.

The refrigeration and freezing apparatus 10 further includes a plurality of internal pipelines 460 disposed in the storage compartment 152, and one of the internal pipelines 460 is connected to a first port 910 and a vent 610 corresponding to the first port 910.

In one example, the vent 610 is provided on the back wall of the storage container 600; the fitting port 154 is provided on a side wall of the liner 150 and is located at a rear section of the liner 150; the internal conduit 460 is disposed on the rear side of the storage container 600 and extends from the first port 910 to the corresponding vent 610.

In some alternative embodiments, the refrigerated chiller 10 also includes an oxygen treatment device 300. The oxygen treatment device 300 has a housing 320 and an electrode pair, the housing 320 defining an electrochemical reaction chamber inside, the electrode pair being disposed in the electrochemical reaction chamber and being configured to transfer external oxygen to the electrochemical reaction chamber through an electrochemical reaction; the housing 320 is provided with an exhaust hole 323 communicating with the electrochemical reaction chamber.

The first end of the air-conditioning pipeline 440 is communicated with the exhaust hole 323, and the second end of the air-conditioning pipeline 440 is communicated with the second interface, so that oxygen in the electrochemical reaction bin is conveyed to the storage compartment, and a high-oxygen fresh-keeping atmosphere is created in the storage space.

In some alternative embodiments, the storage container 600 is drawably disposed within the storage compartment. The refrigeration and freezer 10 may further include an air circuit assembly. Fig. 6 is a schematic configuration diagram of the internal structure of the refrigerating and freezing apparatus 10 shown in fig. 1. Fig. 7 is a schematic exploded view of the internal structure of the refrigerating and freezing apparatus 10 shown in fig. 6, and fig. 8 is a partial enlarged view at C in fig. 7. Fig. 9 is a schematic structural view of the air path adapter 810 of the refrigerating and freezing apparatus 10 shown in fig. 7. Fig. 10 is a schematic perspective view of the air circuit adapter 810 of the refrigeration and freezer 10 shown in fig. 9.

The gas circuit assembly has a tubular connection 820 communicating with the vent 610 and for delivering gas to the storage space. The tubular connector 820 is fixed in the storage compartment, and the tubular connector 820 and the vent 610 are nestable and disengageable with each other during drawing of the storage container 600. The tubular connection 820 may communicate directly or indirectly with the internal conduit mentioned above to direct gas flowing through the internal conduit to the storage space.

The length of the tubular connector 820 is not limited in this embodiment as long as it can provide a ventilation function. For example, the tubular connection 820 may be a ventilation tube segment. An internal conduit may extend from the first port to near the vent 610 to communicate with the tubular connection 820.

By arranging the air path assembly in the storage room and enabling the tubular connecting piece 820 and the air vent 610 of the air path assembly to be mutually nested and detachably arranged in the drawing process of the storage container 600, when the storage container 600 is drawn out, the air vent 610 moves synchronously with the storage container 600, so that the tubular connecting piece 820 and the air vent 610 are detached and separated from each other, and when the storage container 600 is reset, the tubular connecting piece 820 and the air vent 610 can be restored to the mutually nested state so as to be connected with each other. With the above-described aspects of the present utility model, the storage container 600 can receive external air in a drawable condition to adjust the internal atmosphere.

In some alternative embodiments, the air circuit assembly also has a mounting bracket 850 secured within the storage compartment. For example, the mounting bracket 850 may be fixedly coupled to the interior wall of the storage compartment. The manner of fixing connection includes but is not limited to screwing, clamping, welding and riveting.

The mounting bracket 850 has a hollow cylindrical passage into which the tubular connector 820 is inserted to achieve a fixed fit. That is, the tubular connector 820 is fixedly coupled to the mounting bracket 850 to achieve fixation.

The tubular connecting piece 820 is fixed by the mounting bracket 850, so that the tubular connecting piece 820 can be fixed at any position far away from the inner wall of the storage compartment, and the position flexibility of the tubular connecting piece 820 is improved.

In some alternative embodiments, the mounting bracket 850 includes a body portion 851 and a cover portion 852. Wherein, the body part 851 is fixed in the storage compartment and defines a concave arc plate which is concave downwards and takes an arc shape; the concave arc plate serves as the lower channel wall of the hollow cylindrical channel.

The cover portion 852 defines an upwardly concave arcuate plate recessed upwardly and arcuate as the upper channel wall of the hollow cylindrical channel. The upper channel wall and the lower channel wall together form a fixation.

The body portion 851 and the cover portion 852 may be separately provided, not integrally formed. The body portion 851 and the cover portion 852 are utilized to define a hollow cylindrical channel together for arranging the tubular connecting piece 820, and since the body portion 851 and the cover portion 852 can be separately and independently arranged, when the tubular connecting piece 820 is assembled, the tubular connecting piece 820 can be placed on the concave arc plate of the body portion 851 first, and then the cover portion 852 is fixed on the body portion 851, so that the tubular connecting piece 820 can be stably assembled in the hollow cylindrical channel. And when the tubular connecting piece 820 needs to be disassembled, the body part 851 and the cover body part 852 are separated, and the disassembly process is simple and convenient.

The cover 852 is detachably assembled above the body 851. The cover portion 852 also defines a first threaded aperture on either side of the upper channel wall. The body portion 851 is formed with second screw holes located at both sides of the lower passage wall and in one-to-one correspondence with the first screw holes, to be detachably assembled by screw-coupling.

In one example, the vent 610 is located on the back wall of the storage container 600. For example, the body portion 851 may be disposed against a back wall of the storage container 600.

The mounting bracket 850 further includes a bending portion 854, which is formed by bending the end portion of the body portion 851 forward or backward, and is disposed against the sidewall of the storage compartment. The bent portion 854 is provided with a third threaded hole to fixedly assemble the bent portion 854 to the sidewall of the storage compartment by screwing.

When the vent 610 is opened on the back wall of the storage container 600, and the body portion 851 is fixed on the rear side of the storage container 600, and the end portion of the body portion 851 is connected with the bending portion 854 bent forward, because the bending portion 851 can be fixedly connected with the side wall of the storage compartment through the screw connection, based on the above structure, the mounting bracket 850 of the air circuit assembly can be stably assembled in the storage compartment to fix the joint between the air-conditioning pipeline 440 and the vent 610, and on the other hand, the body portion 851 can be fixed at any position far away from the back wall of the storage compartment, so that enough space is reserved between the body portion 851 and the back wall of the storage compartment to arrange the pipeline.

The vent 610 is hollow and cylindrical in shape and protrudes outwardly from the wall of the storage container 600 and at least partially into the hollow cylindrical channel. The first end 821 of the tubular connector 820 defines a hollow cylindrical interface into which the vent port 610 is nested.

When the vent 610 is hollow and cylindrical and extends at least partially into the hollow cylindrical passage and is nested within the hollow cylindrical passage defined by the first end 821 of the tubular connector 820, the storage container 600 is moved in a direction away from the tubular connector 820, so that the vent 610 can be separated from the hollow cylindrical passage defined by the first end 821 of the tubular connector 820, and the storage container 600 is moved in a direction close to the tubular connector 820, so that the vent 610 can be re-nested within the hollow cylindrical passage defined by the first end 821 of the tubular connector 820, and therefore, based on the above structure, the air path connection between the storage container 600 and the tubular connector 820 can be achieved in a detachable manner.

In some alternative embodiments, the air circuit assembly further includes an air circuit adapter 810. Fig. 5 is a schematic structural view of the air path adapter 810 of the refrigerating and freezing apparatus 10 shown in fig. 3. Fig. 6 is a schematic perspective view of the air circuit adapter 810 of the refrigeration and freezer 10 shown in fig. 5.

The air passage adaptor 810 has a first adaptor 811 communicating with the internal pipe and a second adaptor 812 communicating with the second end of the tubular connector 820, and an air flow channel 813 is connected between the second adaptor 812 and the first adaptor 811, so that the internal pipe indirectly communicates with the air vent 610. The air flow channel 813 is arranged obliquely with respect to the horizontal plane.

The temperature of the storage space is generally low. Since the air path adapter 810 is directly connected to the air port 610 of the storage container 600 via the tubular connection 820 and is closely spaced from the storage space, when the temperature of the storage space is low, the temperature of the air path adapter 810 is correspondingly low.

Through setting up the air current passageway 813 of air circuit adaptor 810 for the horizontal plane slope, can make the contained angle between air current passageway 813 and the horizontal plane form acute angle or right angle, when the gas that flows through air circuit adaptor 810 contains moisture and the temperature in storing space is lower, the moisture that the gas carried is difficult for detaining in air current passageway 813 inside, this is favorable to reducing or avoiding air current passageway 813 to block up because of producing the frost and dew, makes between storing space and its external environment realize sustainable gas exchange, and then makes the storing space can maintain low temperature fresh-keeping atmosphere for a long time.

The first and second transfer ports 811 and 812 are hollow cylindrical ports formed by protruding outward from the outer surface of the air path adapter 810, respectively.

The interiors of the first and second transfer ports 811 and 812 respectively define hollow passages communicating with the air flow passage 813 and disposed obliquely with respect to the horizontal plane. That is, the hollow passage of the first transfer port 811 and the hollow passage of the second transfer port 812 are also provided obliquely, respectively.

With the above structure, since the hollow channel of each interface is communicated with the air flow channel 813, this is equivalent to extending the path of the inclined section of the air passage adapter 810, so that the risk of air passage blockage of the air passage adapter 810 can be further reduced, and the air-conditioning pipeline 440 and the air vent 610 can be kept in smooth connection.

In one example, the second end 822 of the tubular connector 820 defines a hollow cylindrical interface into which the second transfer port 812 is nested, and the end of the air conditioning line 440 that communicates with the air vent 610 defines a hollow cylindrical interface into which the first transfer port 811 is nested, such that the internal line indirectly communicates with the air vent 610.

In some alternative embodiments, the gas flow channel 813 of the gas circuit adapter 810 includes a first channel section 813a and a second channel section 813b. Wherein the first channel section 813a communicates with the hollow channel inside the first transfer port 811. The second channel section 813b communicates with the first channel section 813a and communicates with the hollow channel inside the second transfer port 812.

The degree of inclination of the second channel section 813b is set to be different from that of the first channel section 813 a. In other words, the angle between the second channel section 813b and the horizontal plane is different from the angle between the first channel section 813a and the horizontal plane, which may result in different flow rates of the liquid carried by the gas when flowing through the first channel section 813a and the second channel section 813 b.

By arranging two channel sections with different inclinations in the gas circuit adaptor 810, on one hand, the connection mode between each channel section and the corresponding interface can be simplified, and on the other hand, because the flow rates of the gas flowing through the first channel section 813a and the second channel section 813b are different, the risk of gas circuit blockage of the gas flow channel 813 can be further reduced by the scheme of the embodiment.

In some alternative embodiments, the angle between the first channel section 813a and the horizontal is greater than the angle between the second channel section 813b and the horizontal.

With the above scheme, when the air-conditioning pipeline 440 delivers air to the storage space, even if the liquid carried by the air may condense in the first channel section 813a and the second channel section 813b, since the liquid carried by the air may condense in the first channel section 813a first, the flow rate of the liquid beads is larger, and the liquid beads will wash the surface of the second channel section 813b when entering the second channel section 813b, and the liquid beads that condense in the second channel section 813b are wrapped and clamped to continue to flow forward at a high speed, so that the risk of air channel blockage of the air channel adapter 810 is effectively reduced.

In some alternative embodiments, a first transition 811 is formed in an upper section of the air path adapter 810, and a hollow passage inside the first transition 811 is disposed obliquely upward toward a direction away from an outer surface of the air path adapter 810. The central axis of the first channel section 813a is coaxial with the central axis of the hollow channel inside the first swivel joint 811. That is, the degree of inclination of the hollow channel inside the first turn-around port 811 is the same as the degree of inclination of the first channel section 813 a.

The second transfer port 812 is formed at a side section of the air path adapter 810, and is located below the second transfer port 812. The hollow passage inside the second transfer port 812 is disposed obliquely downward toward a direction away from the outer surface of the air passage adapter 810. The central axis of the second channel section 813b is coaxial with the central axis of the hollow channel inside the second swivel port 812. That is, the hollow channel inside the second transfer port 812 is inclined to the same degree as the second channel section 813 b.

Based on the above structure, the internal pipe may be connected to the upper portion of the gas path adapter 810, and the tubular connection member may be connected to the side portion of the gas path adapter 810.

In one example, the ports of the inner tubing may nest within the hollow passage of the first swivel 811 and the tubular connection may nest within the hollow passage of the second swivel 812.

In one example, tubular connector 820 is made of an elastic material. Because the tubular connector 820 made of an elastic material can closely fit the interface nested therein, the use of the tubular connector 820 to communicate the second transfer port 812 with the vent port 610 enables airtight engagement between the second transfer port 812 and the vent port 610.
