[0044] The present application will be described in detail below with reference to the specific embodiments shown in the accompanying drawings.

[0045] In the various figures of the present application, for the sake of convenience, some dimensions of structures or parts are exaggerated relative to other structures or parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present application.

[0046] It should be understood that although the terms "first", "second", "third", etc. may be used in this article to describe various elements, structures or parameters, these described objects should not be limited by these terms. These terms are only used to distinguish these described objects from each other.

[0047] Ginseng Figure 1 As shown, an embodiment of the present application provides a refrigeration device 100, which includes a housing 1, wherein the housing 1 includes an inner liner 11 and an outer shell 12 disposed outside the inner liner 11. The inner liner 11 defines a compartment 2.

[0048] See Figures 2 to 7The refrigeration device 100 further includes a controlled atmosphere container 3, which is housed in the compartment 2. The controlled atmosphere container 3 has a storage space. The so-called controlled atmosphere container means that the concentration of the gas therein can be adjusted according to demand. The gas in this embodiment is oxygen. In other embodiments, the gas can also be set to other types of gases according to demand.

[0049] The refrigeration device 100 further includes a refrigeration system and a cooling air supply path. The cooling air supply path connects the refrigeration system and the compartment 2 and supplies a cooling air flow, ie, cold air, to the outside of the atmosphere-controlled container 3 .

[0050] The atmosphere-controlled container 3 has a cold air channel, and the cold air supply path can also be connected to the interior of the atmosphere-controlled container 3 through the cold air channel.

[0051] See Figures 4 to 6 The refrigeration equipment 100 further includes an oxygen conditioning module 4 and an oxygen conditioning circuit. The oxygen conditioning module 4 is used to prepare an oxygen-conditioned airflow. The oxygen conditioning circuit connects the oxygen conditioning module 4 with the interior of the atmosphere-conditioned container 3 and supplies the oxygen-conditioned airflow to the atmosphere-conditioned container 3. The so-called oxygen-conditioned airflow is used to adjust the concentration of oxygen. Specifically, the oxygen concentration in the oxygen-conditioned airflow is greater than the oxygen concentration in air, which is an oxygen-enriched airflow. Alternatively, the oxygen concentration in the oxygen-conditioned airflow is less than the oxygen concentration in air, which is an oxygen-depleted airflow, thereby adjusting the oxygen concentration.

[0052] The oxygen-adjusting air flow is supplied to the interior of the controlled atmosphere container 3 through the oxygen-adjusting circuit, so that the oxygen concentration inside the controlled atmosphere container 3 can be adjusted, and the water vapor carried in the oxygen-adjusting air flow can increase the humidity in the controlled atmosphere container 3, so as to delay the drying of the food stored in the controlled atmosphere container 3 and improve its preservation effect; the cold air is supplied to the outside of the controlled atmosphere container 3 through the cold air supply circuit, and this part of the cold air circulates outside the controlled atmosphere container 3, thereby taking away part of the heat in the controlled atmosphere container 3, thereby cooling the controlled atmosphere container 3, so as to prevent a large amount of cold air from being sent into the controlled atmosphere container 3 and interfering with the oxygen-adjusting air flow, thereby avoiding large fluctuations in the oxygen concentration therein, and preventing the food from drying out, thereby avoiding affecting the preservation effect; a part of the cold air can be sent into the controlled atmosphere container 3 through the cold air channel, so as to prevent excessive water vapor carried in the oxygen-adjusting air flow from causing condensation or frost in the controlled atmosphere container 3.

[0053] The refrigeration device 100 further includes a power supply and a controller, and the controller is connected to the oxygen regulation module 4 .

[0054] The oxygen regulation module 4 includes at least one anode and at least one cathode, the anode is controllably connected to the positive electrode of the power supply, and the cathode is controllably connected to the negative electrode of the power supply.

[0055] In this way, when the controller controls the oxygen regulating module 4 to operate, under the control of the controller, the positive pole of the power supply is connected to the anode and the negative pole of the power supply is connected to the cathode, that is, the power supply supplies power to the oxygen regulating module 4; and when the controller controls the oxygen regulating module 4 to stop operating, under the control of the controller, the positive pole of the power supply is cut off from the connection with the anode and the negative pole of the power supply is cut off from the connection with the cathode, that is, the power supply stops supplying power to the oxygen regulating module 4.

[0056] Furthermore, the oxygen regulating module 4 further includes an inner cavity capable of accommodating at least electrolyte.

[0057] A first side of the cathode is exposed to the inner cavity, and a second side of the cathode is exposed to the external air of the oxygen regulating module 4 .

[0058] When the oxygen regulating module 4 is in operation, that is, when powered on, the cathode is used to consume oxygen in the external air of the oxygen regulating module 4 through an electrochemical reaction. Specifically, oxygen undergoes a reduction reaction at the cathode, and the reaction formula is O2+2H2O+4e - →4OH - In this way, an oxygen-deficient fresh-keeping atmosphere can be formed outside the oxygen-adjusting module 4, and an oxygen-deficient airflow is formed by sending it into the oxygen-adjusting circuit.

[0059] One side or both sides of the anode are exposed to the inner cavity, and the anode is used to generate oxygen in the inner cavity through electrochemical reaction to form an oxygen-rich fresh-keeping atmosphere. Specifically, OH in the electrolyte - Oxidation reaction can occur at the anode and generate oxygen, the reaction formula is 4OH - →O2+2H2O+4e - The generated oxygen is collected to form an oxygen-rich fresh-keeping atmosphere, and is sent into the oxygen adjustment circuit to form an oxygen-rich air flow.

[0060] The refrigeration system includes a compressor, a condenser, a throttling device and an evaporator connected in sequence.

[0061] In one embodiment, the oxygen concentration within the controlled atmosphere container 3 is greater than that in air, and the oxygen concentration in the controlled atmosphere flow supplied by the controlled atmosphere circuit to the controlled atmosphere container 3 is greater than that in air. In other words, the controlled atmosphere container 3 provides an oxygen-rich environment with a high oxygen concentration. This oxygen-rich environment not only inhibits the growth and reproduction of anaerobic bacteria, but also allows the high concentration of oxygen to combine with deoxymyoglobin on the surface of meat to form a thicker layer of oxymyoglobin, thereby maintaining the bright red color of the meat, improving the color stability of the meat, and thus enhancing the freshness of the meat.

[0062] In another embodiment, the oxygen concentration within the controlled atmosphere container 3 is lower than that in the air, and the oxygen concentration in the controlled atmosphere flow supplied by the controlled atmosphere circuit to the controlled atmosphere container 3 is lower than that in the air. In other words, the controlled atmosphere container 3 provides an oxygen-deficient environment with a low oxygen concentration. This oxygen-deficient environment can inhibit aerobic respiration of fruits and vegetables, reducing the consumption of organic matter such as sugars. It can also minimize anaerobic respiration, thereby preventing the production of substances such as alcohol from anaerobic respiration, which could affect the quality of the fruits and vegetables.

[0063] See Figure 3 The atmosphere-controlled container 3 includes a drawer 32 , a cover 33 and a door 34 . The drawer 32 has a first opening 321 . The cover 33 is used to cover the first opening 321 . The door 34 is connected to the drawer 32 .

[0064] See Figures 2 to 7 The refrigeration equipment 100 includes a cylinder 5, which surrounds the compartment 2. The atmosphere-controlled container 3 is located in the cylinder 5. The cylinder 5 has a second opening 51. The door 34 is used to open or close the second opening 51. The opening directions of the first opening 321 and the second opening 51 are different.

[0065] In this way, there is a space between the controlled atmosphere container 3 and the cylinder 5, and the space forms a circulation air path for cold air, which is conducive to heat exchange with the air in the controlled atmosphere container 3, thereby reducing the temperature in the controlled atmosphere container 3, and avoiding a large amount of cold air from entering the controlled atmosphere container 3 and affecting the oxygen concentration therein, avoiding large fluctuations in the oxygen concentration in the controlled atmosphere container 3, and preventing the food from drying out, thereby avoiding affecting the preservation effect.

[0066] Since the door body 34 is connected to the drawer 32, the drawer 32 can move relative to the cylinder 5 along the opening direction of the second opening 51 and the opposite direction through the movement of the door body 34 relative to the cylinder 5. When the drawer 32 moves to be at least partially located outside the cylinder 5, items can be conveniently stored and retrieved from the drawer 32.

[0067] The cover 33 is fixedly connected to the cylinder 5, so that when the drawer 32 moves relative to the cylinder 5, the drawer 32 also moves relative to the cover 33. When the drawer 32 moves to be at least partially outside the cylinder 5, at least part of the first opening 321 is exposed to the external environment, so that items can be easily stored and retrieved from the drawer 32.

[0068] The drawer 32 has a first position located within the barrel 5 and a second position located outside the barrel 5. When the drawer 32 is in the first position, the cover 33 covers the drawer 32 to control the oxygen concentration inside the controlled atmosphere container 3. When the drawer 32 is in the second position, the cover 33 is offset from the drawer 32. Of course, the interior of the controlled atmosphere container 3 is not a completely enclosed space. The cooling air supply path is provided in the cover 33 or the drawer 32 to allow cooling air to pass through.

[0069] In a specific embodiment, the opening directions of the first opening 321 and the second opening 51 are perpendicular to each other, which is beneficial to the processing of the cylinder 5 and the controlled atmosphere container 3, improves the feasibility, and also makes it easier for the door body 34 to drive the drawer 32 to move relative to the cylinder 5 for storing and retrieving items.

[0070] See Figures 5 to 7 The cylinder 5 is provided with an air inlet 52, which is connected to the refrigeration system and the compartment 2. The cold air channel is provided on the cover 33, and the cold air channel is connected to the interior and exterior of the controlled atmosphere container 3, so that the cold air supply path is connected to the interior of the controlled atmosphere container 3 through the cold air channel to prevent condensation and frost in the controlled atmosphere container 3 due to excessive water vapor in the oxygen-controlled air flow.

[0071] Preferably, the air inlet 52 is provided on the side of the cover 33 facing away from the drawer 32. In this way, at least most of the cold air entering the compartment 2 through the air inlet 52 can be blown toward the side of the cover 33 facing away from the drawer 32, flowing between the cylinder 5 and the drawer 32, thereby performing heat exchange with the drawer 32 and reducing the temperature in the drawer 32.

[0072] The cylinder 5 includes a first wall 53 disposed opposite to the door body 34 , and the air inlet 52 is disposed on the first wall 53 to facilitate the arrangement of the cooling air supply path and shorten the path of the cooling air supply path.

[0073] In one embodiment, the cold air channel is provided in the atmosphere-controlled container 3 near the air inlet 52. In this way, it is ensured that after the cold air enters the compartment 2 from the air inlet 52, that is, after the cold air enters the large space from the small air inlet, there is sufficient power to allow part of the cold air to enter the atmosphere-controlled container 3 from the cold air channel.

[0074] In a specific embodiment, the cold air channel is provided at one end of the cover 33 close to the first wall 53. In this way, the cold air channel is located on the flow path of the cold air, thereby ensuring that after the cold air enters the compartment 2 from the air inlet 52, a portion of the cold air can enter the controlled atmosphere container 3 through the cold air channel.

[0075] In another specific embodiment, the cold air channel is provided on the first wall 53 near the air inlet 52 , so that after the cold air enters the compartment 2 , part of the cold air can enter the atmosphere-controlled container 3 from the cold air channel due to sinking.

[0076] Preferably, a plurality of cold air channels are provided to increase the amount of cold air entering the controlled atmosphere container 3 to a certain extent, so as to achieve the effect of preventing condensation and frosting.

[0077] The plurality of cold air channels are arranged at intervals along a first direction, which is a direction from the first wall 53 toward the door body 34. In this way, it is ensured that after the cold air enters the compartment 3 and flows around the periphery of the controlled atmosphere container 3, when passing through the cover body 33, it can enter the controlled atmosphere container 3 through the plurality of cold air channels, thereby ensuring the amount of cold air entering the controlled atmosphere container 3 and achieving the effect of preventing condensation and frost.

[0078] The cold air channel includes at least one of a slit, a hole 311, and a groove 312. In this way, it is possible to avoid excessive cold air entering the atmosphere-controlled container 3, which would cause a large fluctuation in the oxygen concentration in the atmosphere-controlled container 3.

[0079] In one embodiment, the cold air passage is a slit. Specifically, the cold air passage is a slit between the cover 33 and the drawer 32, through which a small amount of cold air can be controlled to enter the atmosphere-controlled container 3.

[0080] The slit may be provided at one end of the cover body 33 close to the first wall 53 , or may be provided at one end of the first wall 53 close to the cover body 33 .

[0081] See Figures 10 to 12 In another embodiment, the cold air channel is at least one of the hole 311 and the groove 312 to limit the amount of cold air entering the controlled atmosphere container 3 to avoid excessive cold air entering the controlled atmosphere container 3 and causing large fluctuations in the oxygen concentration in the controlled atmosphere container 3.

[0082] In one embodiment, the cold air passage is a hole 311 provided in the cover 33. The cold air passage may include a plurality of holes 311 arranged at intervals. The holes 311 may be located at an end of the cover 33 near the first wall 53 to lower the temperature of the cold air entering the controlled atmosphere container 3. Alternatively, some of the holes 311 may be located at an end of the cover 33 near the first wall 53, while others may be located at an end of the cover 33 away from the first wall 53.

[0083] In another specific embodiment, the cold air channel is a groove 312, and the groove 312 is a square groove 312 or an arc groove 312. The groove 312 is located at one end of the cover 33 close to the first wall 53, so that the cold air enters the controlled atmosphere container 3 at a lower temperature.

[0084] Preferably, a plurality of the grooves 312 are provided, and the plurality of grooves 312 are arranged at intervals.

[0085] See Figure 10 At least one of the plurality of grooves 312 is located at an end of the cover body 33 close to the first wall 53 , and the remaining grooves 312 are located at an end of the cover body 33 away from the first wall 53 .

[0086] In another specific embodiment, the cold air channel includes a hole 311 and a slot 312, and the hole 311 and the slot 312 are spaced apart. Figure 11 It is preferred that a plurality of holes 311 are provided. The hole 311 is provided at one end of the cover body 33 close to the first wall 53, and the groove 312 is provided at one end of the cover body 33 away from the first wall 53. Of course, the positions of the hole 311 and the groove 312 can also be interchanged.

[0087] An air duct plate 111 is provided in the inner tank 11, and the air duct plate 111 is arranged opposite to the door body 34. The air duct plate 111 defines an air duct 1111, and a fan is provided in the air duct 1111. The cooling air supply path passes through the air duct 1111, so that the cooling energy generated by the refrigeration system is sent into the compartment 2 through the cooling air supply path.

[0088] See Figures 2 to 7 The air duct plate 111 is provided with an air supply port 112 , and the air inlet 52 is provided at a position of the cylinder 5 corresponding to the air supply port 112 , and the air inlet 52 is docked with the air supply port 112 and is in communication with each other.

[0089] The oxygen regulating path is located between the air duct plate 111 and the cylinder 5 .

[0090] See Figures 2 to 7 The cylinder 5 is also provided with a return air port 54, and the return air port 54 is also provided on the first wall 53, so as to facilitate the cold air entering the compartment 2 from the air inlet 52 to flow around the periphery of the atmosphere-controlled container 3 and then be discharged from the compartment 2 from the return air port 54.

[0091] The air inlet 52 is located on the side of the cover 33 away from the drawer 32, so that the cold air entering the compartment 2 from the air inlet 52 can sink and then exchange heat with the air in the atmosphere container 3 to improve the cooling efficiency.

[0092] In the opening direction of the first opening 321, the return air vent 54 is located on the side of the cover 33 away from the air inlet 52. This facilitates cold air entering the compartment 2 from the air inlet 52, circulating around the periphery of the controlled atmosphere container 3, and then being discharged from the compartment 2 through the return air vent 54.

[0093] See Figures 7 to 9 The atmosphere-controlled container 3 further includes a connecting portion 35 , which connects the drawer 32 and the door 34 .

[0094] The connecting portion 35 is provided with a plurality of vents 351. Thus, after cold air enters the compartment 2 from the air inlet 52, it flows through the space between the cover 33 and the cylinder 5 toward the door 34. After flowing to a position close to the door 34, it passes through the plurality of vents 351 and flows into the space between the drawer 32 and the door 34. Then, it flows from the side of the drawer 32 away from the cover 33 toward the return air vent 54. In this way, the cold air can circulate around the periphery of the controlled atmosphere container 3 and then be discharged from the compartment 2 through the return air vent 54.

[0095] See Figures 10 and 11 In one embodiment, the oxygen regulating circuit includes a gas regulating inlet 331 provided on the cover body 33 , and the gas regulating inlet 331 connects the interior and exterior of the gas regulating container 3 , and the oxygen regulating circuit is connected to the interior of the gas regulating container 3 through the gas regulating inlet 331 .

[0096] The oxygen regulating circuit further includes a pipe joint 55 fixedly provided on the cylinder 5 , one end of the pipe joint 55 is plugged into and fitted with the gas regulating inlet 331 , and the other end of the pipe joint 55 is exposed to the outer wall of the cylinder 5 .

[0097] The oxygen regulating circuit may further include an air pipe, one end of which is connected to the oxygen regulating module 4 and the other end is connected to the pipe joint 55 . Specifically, the other end is connected to an end of the pipe joint 55 exposed to the outer wall of the cylinder 5 .

[0098] In this way, the oxygen-regulated airflow prepared by the oxygen-regulated module 4 can be sequentially delivered into the atmosphere-regulated container 3 through the air pipe, the pipe joint 55, and the atmosphere-regulated inlet 331, thereby preventing the oxygen-regulated airflow from entering the compartment 2 but being located outside the atmosphere-regulated container 3, thereby preventing the food stored in the atmosphere-regulated container 3 from being preserved.

[0099] The outer wall of the controlled atmosphere container 3 is further provided with a panel 36. The panel 36 surrounds the controlled atmosphere inlet 331 and extends from the outer wall of the cover 33 to the inner wall of the cylinder 5. This prevents other components from interfering with the connection between the pipe joint 55 and the controlled atmosphere inlet 331.

[0100] In summary, the refrigeration device 100 of the present application supplies an oxygen-adjusting air flow to the interior of the controlled atmosphere container 3 through the oxygen-adjusting circuit, which can adjust the oxygen concentration inside the controlled atmosphere container 3, and the water vapor carried in the oxygen-adjusting air flow can increase the humidity in the controlled atmosphere container 3, so as to delay the drying of the food stored in the controlled atmosphere container 3 and improve its preservation effect; cold air is supplied to the outside of the controlled atmosphere container 3 through the cold air supply circuit, and this part of the cold air circulates on the outside of the controlled atmosphere container 3, thereby taking away part of the heat in the controlled atmosphere container 3, thereby cooling the controlled atmosphere container 3, so as to avoid a large amount of cold air being sent into the controlled atmosphere container 3 and interfering with the oxygen-adjusting air flow, thereby avoiding large fluctuations in the oxygen concentration therein, and preventing the food from drying out, thereby avoiding affecting the preservation effect; a part of the cold air can be sent into the controlled atmosphere container 3 through the cold air channel, so as to prevent excessive water vapor carried in the oxygen-adjusting air flow from causing condensation and frost in the controlled atmosphere container 3.
