Description

Technical Field

[0001] This application relates to the technical field of household appliances, and more particularly to a refrigerator. Background Technology

[0002] With the improvement of modern living standards, people have increasingly higher requirements for food preservation. As the main storage area for food, the refrigerator's crisper compartment directly affects the quality and taste of food. Traditional refrigeration technology mainly relies on temperature control to extend the shelf life of food, but this method cannot completely inhibit oxidation reactions and microbial growth. Therefore, refrigerator crisper compartment deoxygenation technology has emerged as an important means to improve food preservation. Utility Model Content

[0003] In view of the shortcomings of the related technologies, this application provides a refrigerator that uses an ozone generator to react oxygen in the refrigerator compartment into ozone, uses an adsorption element to adsorb the ozone, and uses an air pump to discharge the ozone that is not adsorbed by the adsorption element to the outside of the refrigerator compartment, so as to reduce the oxygen concentration in the refrigerator compartment and extend the food preservation time.

[0004] This application provides a refrigerator, including:

[0005] The cabinet has an internally defined refrigerator compartment, and the cabinet has an opening for the refrigerator compartment, which is connected to the refrigerator compartment.

[0006] The refrigerator door, located at the opening of the refrigerator compartment, is used to open or close the refrigerator compartment;

[0007] An ozone generator, located in a cold storage room, is used to react oxygen in the air into ozone;

[0008] An adsorption element, located in the cold storage compartment, is used to adsorb ozone;

[0009] An air pump is located inside the refrigerator compartment. The air inlet of the air pump is located on the side of the adsorbent that is away from the ozone generator, and the exhaust port of the air pump is connected to the outside of the refrigerator compartment.

[0010] The ozone generator, adsorbent, and air pump are arranged sequentially along the airflow path. Part of the ozone generated by the ozone generator is adsorbed by the adsorbent, and the other part is discharged to the outside of the cold storage compartment by the air pump.

[0011] This technical solution reduces the oxygen concentration in the refrigerator compartment by using an ozone generator to react oxygen in the air. It also uses an adsorption unit to absorb the ozone generated by the generator, preventing it from being converted back to oxygen. Furthermore, an air pump removes any unabsorbed ozone from the refrigerator compartment, further enhancing the deoxygenation effect. The air pump also generates airflow that flows from the ozone generator to the adsorption unit, ensuring sufficient contact between the ozone and the unit and increasing its adsorption capacity.

[0012] In some embodiments of this application, a fan is also included, which is located in a cold storage room and is configured to blow ozone generated by an ozone generator toward the adsorption element.

[0013] This technical solution uses a fan to blow ozone generated by the ozone generator toward the adsorption element, thereby increasing the contact efficiency between ozone and the adsorption element. It can also restrict the movement path of the ozone, allowing the ozone to fully contact the adsorption element and increasing the adsorption effect of the adsorption element.

[0014] In some embodiments of this application, the fan, ozone generator, adsorption element and air pump are arranged sequentially along the airflow path, with the fan located near the beginning of the airflow path and the air pump located near the end of the airflow path.

[0015] This technical solution arranges the fan, ozone generator, adsorption element, and extraction pump sequentially along the airflow path, with the fan positioned near the beginning of the airflow path and the extraction pump near the end. This ensures that the airflow first contacts the ozone generator, then the adsorption element, and finally is exhausted to the outside of the refrigerator compartment by the extraction pump. This prevents ozone from flowing freely within the refrigerator compartment and ensures that ozone is exhausted to the outside of the refrigerator compartment as much as possible, thereby guaranteeing the deoxygenation effect of the air inside the refrigerator compartment.

[0016] In some embodiments of this application, the adsorption element is installed in the mounting box, the air outlet of the mounting box is connected to the air inlet of the air pump, the air inlet of the mounting box is set towards the air outlet of the fan, and the air inlet and air outlet of the mounting box are respectively set on opposite side walls of the mounting box.

[0017] This technical solution uses an installation box to install the adsorption component. This not only facilitates the installation and setup of the adsorption component, but also restricts airflow, preventing the air in contact with the adsorption component from flowing freely and ensuring that the air inside the installation box can be exhausted to the outside of the refrigerator compartment by the air pump.

[0018] In some embodiments of this application, a pre-embedded box is also included, which is installed in the cabinet and located at the top of the cold storage compartment; the fan, ozone generator, adsorption component and air pump are respectively located in the pre-embedded box.

[0019] This technical solution involves setting up a pre-embedded box, which is used to install a fan, ozone generator, adsorption component, and air pump. By placing the pre-embedded box on the top of the cold storage compartment, the ozone generator and adsorption component can remove oxygen from the air throughout the entire cold storage compartment.

[0020] In some embodiments of this application, the pre-embedded box is defined to form a first cavity, an intermediate cavity and a second cavity, which are distributed sequentially along the flow path of the airflow; the first cavity and the intermediate cavity are interconnected, and the intermediate cavity and the second cavity are interconnected; a fan is disposed in the first cavity, an ozone generator and an adsorption element are disposed in the intermediate cavity, and an air pump is disposed in the second cavity.

[0021] This technical solution involves setting up a first cavity, an intermediate cavity, and a second cavity in a pre-embedded box. A fan is installed in the first cavity, an ozone generator and an adsorption component are installed in the intermediate cavity, and an air pump is installed in the second cavity. This allows the first cavity and the intermediate cavity to be interconnected, and the intermediate cavity and the second cavity to be interconnected, avoiding direct connection between the first cavity and the second cavity. This ensures the airflow path within the pre-embedded box and thus guarantees the deoxygenation effect of the air in the cold storage room.

[0022] In some embodiments of this application, the side of the pre-embedded box facing the refrigerator compartment is provided with an air inlet that communicates with the refrigerator compartment, and the air inlet of the fan is connected to the air inlet.

[0023] This technical solution involves setting an air inlet on the side of the pre-embedded box facing the refrigerator compartment, connecting the refrigerator compartment and the interior of the pre-embedded box, and aligning the air inlet of the fan with the air outlet. This allows air from the refrigerator compartment to enter the pre-embedded box through the air inlet under the operation of the fan, forming an airflow that blows the ozone generated by the ozone generator toward the adsorption element. Furthermore, when the airflow blows toward the ozone generator, it allows the ozone generator to react the oxygen in the airflow into ozone.

[0024] In some embodiments of this application, the side of the pre-embedded box facing the cold storage compartment is provided with a pick-and-place section for the adsorbent and / or ozone generator to enter and exit the pre-embedded box, and the adsorbent and / or ozone generator are provided corresponding to the pick-and-place section.

[0025] This technical solution provides a pick-and-place section in the pre-embedded box, allowing the adsorption component and / or ozone generator to pass through the pick-and-place section into and out of the pre-embedded box, thus facilitating the maintenance and replacement of the adsorption component and / or ozone generator.

[0026] In some embodiments of this application, the pre-embedded box includes a box body and a cover body, the box body and the cover body together define a first cavity and a second cavity, the first cavity and the second cavity are respectively disposed at both ends of the box body in the length direction; the intermediate cavity is disposed in the cover body, and the two sides of the intermediate cavity disposed opposite to each other in the length direction of the box body are respectively provided with connecting portions, so that the intermediate cavity communicates with the first cavity and / or the second cavity.

[0027] This technical solution designs the embedded box as a separate structure consisting of a box body and a cover, which not only facilitates the installation of the embedded box into the enclosure, but also facilitates the installation of components such as fans and air pumps inside the embedded box.

[0028] In addition, this application also provides a refrigerator, comprising:

[0029] The cabinet has an internally defined refrigerator compartment, and the cabinet has an opening for the refrigerator compartment, which is connected to the refrigerator compartment.

[0030] The refrigerator door, located at the opening of the refrigerator compartment, is used to open or close the refrigerator compartment;

[0031] An ozone generator, located in a cold storage room, is used to react oxygen in the air into ozone;

[0032] An adsorption element, located in the cold storage compartment, is used to adsorb ozone;

[0033] A fan, located in the cold storage room, is configured to blow ozone generated by the ozone generator toward the adsorption element;

[0034] An embedded box is installed in the cabinet; an air duct is defined within the embedded box, and the air duct is at least connected to the interior of the refrigerator compartment; a fan, an ozone generator, and an adsorption unit are sequentially arranged in the air duct along the airflow path, wherein the fan is located near the beginning of the airflow path, and the adsorption unit is located near the end of the airflow path.

[0035] This technical solution reduces the oxygen concentration in the refrigerator compartment by setting up an ozone generator to react oxygen in the air with ozone. It also uses an adsorbent to absorb the ozone generated by the generator, preventing it from being converted back to oxygen. Furthermore, a fan creates airflow that directs the ozone from the generator towards the adsorbent, increasing the contact efficiency between the ozone and the adsorbent. The fan can also restrict the ozone's movement path, ensuring sufficient contact between the ozone and the adsorbent and enhancing its adsorption effect.

[0036] The refrigerator described above uses an ozone generator to react oxygen in the air inside the refrigerator compartment into ozone. An adsorption unit then adsorbs the ozone generated by the generator, and a vacuum pump expels any unadsorbed ozone outside the refrigerator compartment to prevent it from reacting back into oxygen. This reduces the oxygen concentration inside the refrigerator compartment and extends the shelf life of items. Furthermore, a fan creates airflow, which not only directs the ozone generated by the generator towards the adsorption unit, increasing the contact efficiency between ozone and the unit, but also restricts the ozone's movement path, ensuring sufficient contact and enhancing the adsorption effect.

[0037] The refrigerators mentioned above have good deoxygenation effects in the refrigerator compartment and have a simple overall structure that is easy to arrange. Attached Figure Description

[0062] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0063] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0064] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0065] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0066] The refrigerator provided in this application has various specific implementations. The refrigerator can be a double-door refrigerator, a single-door refrigerator, a refrigerator with only refrigeration function, or a refrigerator with both refrigeration and freezing functions.

[0067] The refrigerator includes a cabinet that forms the overall appearance of the refrigerator. The cabinet defines a refrigerator compartment 101, which is used to preserve food and other items, slowing down their spoilage and deterioration; the temperature inside the refrigerator compartment 101 is typically above zero degrees Celsius. An opening for the refrigerator compartment 101 is formed on the cabinet, communicating with the refrigerator compartment 101, through which items can be placed into or removed from the refrigerator compartment 101.

[0068] like Figure 1 and Figure 2 As shown, the cabinet includes an inner liner 100, which defines the refrigerator compartment 101 and the opening of the refrigerator compartment 101. The opening of the refrigerator compartment 101 is located on the front side of the inner liner 100. The outer periphery of the inner liner 100 is provided with foam material so that the refrigerator compartment 101 can maintain a low temperature environment.

[0069] The inner liner 100 has a top and a bottom, with the top and bottom of the inner liner 100 being opposite ends. The direction from the top to the bottom of the inner liner 100 is the height direction. The left and right sides of the inner liner 100 are opposite sides, with the direction from the left to the right side of the inner liner 100 being the width direction. The front and rear sides of the inner liner 100 are opposite sides, with the direction from the front to the rear side of the inner liner 100 being the thickness direction. It should be noted that the height, thickness, and width directions of the inner liner 100 correspond to the height, thickness, and width directions of the outer casing.

[0070] In practical applications, the front of the refrigerator compartment usually faces the user, and the rear of the refrigerator compartment usually faces the wall. In this embodiment, the opening of the refrigerator compartment 101 faces the front of the inner liner 100.

[0071] The refrigerator includes a door, which is located at the opening of the refrigerator compartment 101 and is used to open or close the refrigerator compartment 101 so that the refrigerator compartment 101 can maintain a low temperature environment; the door is usually rotatably connected to the cabinet, and the rotatability includes, but is not limited to, hinges.

[0072] like Figure 1 and Figure 2 As shown, the refrigerator includes an oxygen removal module 200, which is used to reduce the oxygen concentration in the refrigerator compartment 101 and extend the shelf life of items.

[0073] like Figure 5 As shown, the deoxygenation module 200 includes an ozone generator 270, which reacts oxygen in the air inside the refrigerator compartment 101 into ozone to reduce the oxygen content in the air. The specific structure and working principle of the ozone generator 270 are prior art in this field and will not be described in detail here.

[0074] like Figure 6 As shown, the deoxygenation module 200 includes an adsorption element 280, which is used to adsorb ozone generated by the ozone generator 270 to prevent ozone from being reacted into oxygen.

[0075] In some embodiments, the adsorbent 280 is typically activated carbon, a porous carbonaceous material with numerous micropores and a large surface area, giving it a strong adsorption capacity. When ozone molecules come into contact with the surface of activated carbon, they are adsorbed into the micropores due to the unsaturated bonds on the activated carbon surface and the intermolecular forces.

[0076] like Figure 5As shown, the deoxygenation module 200 includes a fan 260, which blows ozone generated by the ozone generator 270 toward the adsorption element 280, causing the ozone to be adsorbed by the adsorption element 280. The fan 260, the ozone generator 270, and the adsorption element 280 are arranged sequentially along the airflow path, with the adsorption element 280 located upstream of the ozone generator 270 along the airflow direction.

[0077] The fan 260 operates to create an airflow, which flows towards the ozone generator 270 and carries the ozone produced by the ozone generator 270 towards the adsorbent 280, causing the ozone to be adsorbed by the adsorbent 280. By creating an airflow through the fan 260 and specifying the flow path for the ozone, not only can the adsorbent 280 fully absorb the ozone, but the adsorption efficiency of the adsorbent 280 for ozone can also be increased.

[0078] like Figure 5 As shown, the air outlet of the fan 260 is positioned facing the adsorption element 280, and the ozone generator 270 is located between the air outlet of the fan 260 and the adsorption element 280 along the airflow path. The ozone generator 270 is located on the airflow path and between the air outlet of the fan 260 and the adsorption element 280, so that the airflow carries the ozone generated by the ozone generator 270 towards the adsorption element 280.

[0079] like Figure 4 and Figure 5 As shown, the deoxygenation module 200 includes an air pump 250, which is used to discharge ozone that has not been adsorbed by the adsorbent 280 to the outside of the refrigerator compartment 101 through the exhaust pipe 300. The exhaust port of the air pump 250 is connected to the exhaust pipe 300, and the end of the exhaust pipe 300 away from the air pump 250 is located outside the refrigerator compartment 101. The air inlet of the air pump 250 is located close to the adsorbent 280, and by drawing the air around the adsorbent 280 to the outside of the refrigerator compartment 101, the ozone that has not been adsorbed around the adsorbent 280 is discharged to the outside of the refrigerator compartment 101.

[0080] In some embodiments of the present application, Figure 6 and Figure 7 As shown, the adsorbent 280 is installed inside the mounting box 240. The mounting box 240 is provided with an air outlet, which is connected to the air inlet of the vacuum pump 250 so that the vacuum pump 250 can draw air from the mounting box 240, thereby ensuring that the ozone in the mounting box 240 that is not adsorbed by the adsorbent 280 can be discharged to the outside of the cold storage compartment 101.

[0081] like Figure 6 As shown, the mounting box 240 is provided with a ventilation section 241. The ventilation section 241 is located on the side of the mounting box 240 facing the fan 260. The ventilation section 241 is arranged corresponding to the air outlet of the fan 260 so that the airflow generated by the fan 260 enters the mounting box 240 through the ventilation section 241 and contacts the adsorption component 280.

[0082] In some embodiments, the ventilation section 241 is the air inlet of the mounting box 240.

[0083] By installing the adsorbent 280 inside the mounting box 240, it is convenient to place the adsorbent 280, and it can ensure the adsorption effect of the adsorbent 280 on ozone. It can also ensure that the air pump 250 can discharge the unadsorbed ozone to the outside of the cold storage compartment 101, thereby ensuring the deoxygenation effect of the deoxygenation module 200.

[0084] The refrigerator includes a pre-embedded box installed in the inner liner 100. An air duct is defined within the pre-embedded box. A fan 260, an ozone generator 270, an adsorption component 280, and an air pump 250 are sequentially distributed within the air duct along the airflow path. The pre-embedded box not only allows the fan 260, ozone generator 270, adsorption component 280, and air pump 250 to be installed, but also allows the pre-embedded box to constrain and limit the airflow path to ensure the deoxygenation effect of the air in the refrigerator compartment 101.

[0085] like Figure 12 As shown, the pre-embedded box is defined by forming a first cavity 204, which is located at the starting end of the airflow path within the pre-embedded box, and the fan 260 is installed in the first cavity 204.

[0086] like Figure 9 As shown, the embedded box is defined by forming a second cavity 201, which is located at the end of the airflow path inside the embedded box, and the air pump 250 is installed inside the second cavity 201.

[0087] like Figure 9 As shown, the embedded box defines an intermediate cavity 202, which is located between the first cavity 204 and the second cavity 201 along the airflow path inside the embedded box. The ozone generator 270 and the adsorption element 280 are disposed in the intermediate cavity 202.

[0088] like Figure 13 As shown, the intermediate cavity 202 is connected to the first cavity 204 through the first connecting part 206, so that the airflow generated by the fan 260 can be blown sequentially toward the ozone generator 270 and the adsorption element 280.

[0089] like Figure 9 As shown, the intermediate cavity 202 is connected to the second cavity 201 through the second connecting part 207, so that the air pump 250 can exhaust the air in the intermediate cavity 202 to the outside of the refrigerator compartment 101, thereby exhausting the ozone in the intermediate cavity 202 that has not been adsorbed by the adsorbent 280 to the outside of the refrigerator compartment 101.

[0090] It should be noted that the first connecting part 206 and the second connecting part 207 are respectively provided on the two side walls of the intermediate cavity 202 along the length direction of the embedded box, so that the first cavity 204 and the second cavity 201 are connected through the intermediate cavity 202, avoiding direct connection between the first cavity 204 and the second cavity 201. This ensures that the air first acts on the ozone generator 270, then on the adsorption element 280, and finally is discharged to the outside of the refrigerator compartment 101 by the air pump 250. This ensures the deoxygenation effect of the air in the refrigerator compartment 101, prevents the airflow from being discharged to the outside of the refrigerator compartment 101 by the air pump 250 without passing through the ozone generator 270, and also prevents the ozone content in the air discharged to the outside of the refrigerator compartment 101 by the air pump 250 from being low, while excess ozone remains in the refrigerator compartment 101.

[0091] like Figure 10 As shown, the embedded box is provided with an air inlet 203 on the side facing the refrigerator compartment 101. The air inlet 203 is connected to the first cavity 204. The air inlet of the fan 260 is correspondingly set with the air inlet 203. When the fan 260 is running, the air in the refrigerator compartment 101 enters the fan 260 through the air inlet of the fan 260 via the air inlet of the air inlet 203, and then blows towards the middle cavity 202.

[0092] Since the adsorbent 280 and / or ozone generator 270 need to be replaced periodically, in order to facilitate the removal and placement of the adsorbent 280 and / or ozone generator 270, a removal and placement part is provided on the side of the pre-embedded box facing the refrigerator compartment 101. The removal and placement part is used for the adsorbent 280 and / or ozone generator 270 to enter and exit the pre-embedded box. The removal and placement part is connected to the intermediate cavity 202, and the adsorbent 280 and / or ozone generator 270 are set correspondingly to the removal and placement part.

[0093] like Figure 7 As shown, the air pump 250 includes a pump body 252, the air inlet of the pump body 252 is connected to the air outlet of the mounting box 240, and the air outlet of the pump body 252 is connected to the exhaust pipe 300.

[0094] The air pump 250 includes a pump sleeve 251 and a pump body 252 located inside the pump sleeve 251. The pump sleeve 251 is connected to the embedded box by fasteners such as bolts or screws. A shock absorber 400 is provided at the connection between the pump sleeve 251 and the embedded box. The shock absorber 400 is used to absorb the vibration generated when the air pump 250 is working.

[0095] It should be noted that when the air pump 250 is working, the air inside the embedded box flows towards the air inlet of the air pump 250, thereby generating airflow. In this embodiment, the airflow generated by the operation of the fan 260 has the same flow path and direction as the airflow generated by the operation of the air pump 250, in order to ensure the reliability and orderliness of the airflow inside the embedded box, thereby ensuring the deoxygenation effect.

[0096] In some embodiments of this application, the fan 260, ozone generator 270, adsorption element 280, and air pump 250 are arranged along the length of the pre-embedded box. The air outlet of the fan 260 is set towards the ozone generator 270, and the air outlet of the air pump 250 is set towards the adsorption element 280. The fan 260 generates airflow, which is blown from the air outlet of the fan 260 along the airflow path to the ozone generator 270 and the adsorption element 280 in sequence. This causes the ozone generated by the ozone generator 270 to be blown towards the adsorption element 280, thereby increasing the adsorption effect of the adsorption element 280 on ozone.

[0097] In this application, the embedded box is designed as a split structure, which not only facilitates the installation of the embedded box into the inner liner 100, but also facilitates the installation of the ozone generator 270, adsorption component 280, fan 260 and air pump 250 in the embedded box.

[0098] like Figure 3 and Figure 4 As shown, the pre-embedded box includes a box body 230, which is located on the outside of the inner liner 100. The first cavity 204 and the second cavity 201 are located inside the box body 230. The fan 260 and the air pump 250 are installed in the box body 230.

[0099] like Figure 8 As shown, the inner liner 100 is provided with a reserved opening 102, and the box body 230 is located at the reserved opening 102. The cavity inside the box body 230 is connected to the refrigerator compartment 101 through the reserved opening 102.

[0100] The box body 230 has an opening on the side facing the refrigerator compartment 101 to facilitate the installation of components such as the fan 260 and the air pump 250 inside the box body 230.

[0101] like Figure 10 As shown, a contact portion 232 is provided at the outer edge of the box body 230. The contact portion 232 contacts the outer edge of the reserved opening 102 to prevent the box body 230 from passing through the reserved opening 102. It can also increase the contact area between the box body 230 and the inner liner 100 and increase the firmness of the connection between the box body 230 and the inner liner 100.

[0102] like Figure 9 As shown, the pre-embedded box includes a cover 220, which is located inside the refrigerator compartment 101. The cover 220 is located at the opening of the box body 230 and is used to seal the opening of the box body 230 so that the fan 260 and the air pump 250 are firmly installed in the receiving cavity.

[0103] The cover 220 is detachably connected to the box 230 so as to facilitate the installation of components such as the fan 260 and the air pump 250 inside the box 230.

[0104] like Figures 11-13As shown, the cover 220 is provided with a first connecting part 222. The first connecting part 222 is located on one side of the cover 220 extending along its length direction. The first connecting part 222 is connected to the outer extension of the box 230 by fasteners such as bolts or screws.

[0105] like Figures 11-13 As shown, the cover 220 is provided with a protrusion 226, which is located on the other side of the cover 220 extending along its length. The protrusion 226 protrudes from the outer edge of the cover 220 and is inserted into the box 230 so that the box 230 constrains the cover 220 and connects the cover 220 and the box 230 to each other.

[0106] like Figure 10 As shown, the box body 230 is provided with an insertion part 233. The insertion part 233 is provided on one side of the box body 230 extending along its length direction. The insertion part 233 is correspondingly provided with the protrusion 226. The protrusion 226 extends into the insertion part 233 so that the box body 230 constrains the cover 220 and prevents the cover 220 from separating from the box body 230.

[0107] like Figure 13 As shown, the cover 220 is provided with a first snap-fit ​​part 227, which is located on the same side of the cover 220 as the first connecting part 222. The first snap-fit ​​part 227 is connected to the box body 230.

[0108] like Figure 5 As shown, the box body 230 is provided with a second latching part 231. The second latching part 231 is provided on the other side of the box body 230 extending along its length direction. The second latching part 231 is correspondingly provided with the first latching part 227. The first latching part 227 is connected to the second latching part 231 so that the cover 220 and the box body 230 are connected to each other.

[0109] When the cover 220 is connected to the box 230, the protrusion 226 is first placed in the insertion part 233, and the first snap-fit ​​part 227 is placed in the second snap-fit ​​part 231, so that the box 230 and the cover 220 are initially positioned and constrained. Then, the first connecting part 222 and the box 230 are connected to each other by fasteners such as bolts or screws.

[0110] It should be noted that after the protrusion 226 is provided in the insertion part 233, the first latching part 227 may interfere with the second latching part 231. By deforming the first latching part 227, the first latching part 227 can be provided in the second latching part 231, thereby connecting the cover 220 to the box 230. This is a conventional technical means in the field and will not be described in detail.

[0111] In some embodiments, a pre-embedded box is disposed at the top of the refrigerator compartment 101 so that the deoxygenation module 200 can deoxygenate the air in the entire refrigerator compartment 101, thereby increasing the working space of the deoxygenation module 200.

[0112] The cover 220 and the box 230 together define the first cavity 204 and the second cavity 201. The cover 220 defines the intermediate cavity 202. The take-up and put-down part is provided on the cover 220 so that the adsorption member 280 and the ozone generator 270 can be repaired or replaced without removing the cover 220.

[0113] In some embodiments, the take-up portion is an opening provided in the cover 220 so that the adsorption member 280 and the ozone generator 270 can pass through the take-up portion and be placed in the intermediate cavity 202.

[0114] In this embodiment, the airflow flows along the length of the box 230 within the pre-embedded box. Therefore, the first cavity 204 and the second cavity 201 are respectively located at both ends of the length of the box 230.

[0115] In some embodiments, the air inlet 203 is an opening provided in the cover 220 so that air in the refrigerator compartment 101 enters the interior of the fan 260 through the air inlet 203.

[0116] like Figure 12 and Figure 13 As shown, the cover 220 is provided with a guide portion 224, which is located in the first cavity 204. One end of the guide portion 224 is located at the air outlet of the fan 260, and the other end of the guide portion 224 is located in the first connecting portion 206. The guide portion 224 is used to define the formation of the air outlet duct 205 so that the airflow generated by the fan 260 flows through the air outlet duct 205 to the intermediate cavity 202, and can also prevent the airflow generated by the fan 260 from flowing from the inside of the box 230 to the air pump 250.

[0117] It should be noted that the air outlet of the fan 260 is located at the air inlet of the air outlet duct 205, and the first connecting part 206 is located at the air outlet of the air outlet duct 205.

[0118] like Figure 12 and Figure 13 As shown, the cover 220 is provided with a constraint part 225, which extends along the length of the cover 220. The constraint part 225 is used to restrict the routing of the exhaust pipe 300 in the embedded box and prevent the exhaust pipe 300 from shaking in the embedded box.

[0119] In some embodiments of this application, such as Figure 11As shown, the cover 220 is provided with a mounting part 223 for mounting the ozone generator 270. The mounting part 223 protrudes from the cavity wall of the intermediate cavity 202. The ozone generator 270 is mounted and fixed by the mounting part 223 to prevent the ozone generator 270 from moving when the airflow blows towards it, thereby reducing the working stability and reliability of the ozone generator 270.

[0120] The mounting part 223 has a guide surface on the side facing the adsorbent 280. The guide surface is used to guide the airflow to the adsorbent 280. The airflow is guided from the ozone generator 270 to the adsorbent 280 by the guide surface to increase the contact effect between the airflow and the adsorbent 280, thereby increasing the adsorption effect of the adsorbent 280 on ozone.

[0121] like Figure 3 As shown, the refrigerator includes a decorative piece 210, which is connected to the cover 220. The decorative piece 210 is located on the side of the cover 220 away from the box body 230 and is used to cover the cover 220 and the suction piece 280 to ensure the aesthetics of the refrigerator compartment 101.

[0122] like Figure 13 As shown, the decorative part 210 is provided with several ventilation holes so that air in the refrigerator compartment 101 passes through the ventilation holes, enters the fan 260 through the air inlet 203.

[0123] It should be noted that the air in the refrigerator compartment 101 can also enter the intermediate cavity 202 through the vent and interact with the ozone generator 270.

[0124] like Figure 11 As shown, the cover 220 is provided with a fixing part 221. The fixing part 221 is located on the side of the cover 220 away from the box body 230. The fixing part 221 is located near the side of the cover 220 that is arranged along the length direction of the cover 220. The fixing part 221 is connected to the decorative part 210 and is used to fix the decorative part 210.

[0125] like Figure 14 As shown, the decorative part 210 is provided with a second connecting part 211, which is correspondingly provided with the fixing part 221. The second connecting part 211 is inserted into the fixing part 221 so that the decorative part 210 and the cover 220 are connected to each other.

[0126] like Figure 13 As shown, the cover 220 is provided with a limiting part 228. The limiting part 228 is provided on the other side of the cover 220 along the length direction of the cover 220. The limiting part 228 is used to limit the connection position between the decorative part 210 and the cover 220.

[0127] like Figure 14As shown, the decorative part 210 is provided with a third connecting part 212, which is correspondingly provided with the limiting part 228. The third connecting part 212 is engaged with the limiting part 228 to position the connection between the decorative part 210 and the cover 220.

[0128] During installation, the decorative part 210 is first positioned within the limiting part 228, and then the second connecting part 211 is positioned within the fixing part 221, so that the decorative part 210 is connected to the cover 220. It should be noted that after the third connecting part 212 is positioned within the limiting part 228, the second connecting part 211 may interfere with the fixing part 221. By deforming the second connecting part 211, it can be positioned within the fixing part 221. This is common knowledge in the art and will not be elaborated further.

[0129] The deoxygenation principle of the refrigerator is as follows: the fan 260 operates, drawing air from the refrigerator compartment 101 into the fan 260 and blowing it from the fan 260 outlet through the air outlet duct 205 to the intermediate cavity 202. The ozone generator 270 reacts the oxygen in the air in the intermediate cavity 202 into ozone. The fan 260 blows air towards the intermediate cavity 202 to form an airflow, which carries the ozone to the adsorption element 280. Some of the ozone is adsorbed by the adsorption element 280, and the ozone not adsorbed by the adsorption element 280 is discharged to the outside of the refrigerator compartment 101 by the air pump 250.

[0130] It should be noted that although the air pump 250 is expelling air from the refrigerator compartment 101, a true vacuum will not be created inside the refrigerator compartment 101. This will not cause the inner liner 100 to deform or the door to be difficult to open. This is because users will open the door from time to time to take out or put in items, and the air inside the refrigerator compartment 101 will be replenished when the door is opened. On the other hand, there will be a certain gap between the door and the cabinet, and air will enter the refrigerator compartment 101 through the gap between the cabinet and the door.

[0131] The refrigerator described above utilizes an ozone generator 270 to react oxygen in the air within the refrigerator compartment 101 into ozone, and an adsorbent 280 to adsorb the ozone generated by the ozone generator 270, preventing the ozone from being reacted into oxygen, thereby reducing the oxygen concentration in the refrigerator compartment 101 and extending the preservation time of the items inside. The operation of the fan 260 creates airflow, which not only directs the ozone generated by the ozone generator 270 towards the adsorbent 280, increasing the contact efficiency between the ozone and the adsorbent 280, but also restricts the movement path of the ozone, allowing it to... To ensure sufficient contact between the ozone generator and the adsorbent 280, the adsorption effect of the adsorbent 280 is increased. The air pump 250 is used to discharge the ozone that has not been adsorbed by the adsorbent 280 to the outside of the refrigerator compartment 101 to prevent the ozone from being reacted into oxygen and to increase the deoxygenation effect of the air in the refrigerator compartment 101. The air pump 250 can also generate airflow, which flows along the ozone generator 270 to the adsorbent 280, so that the ozone generated by the ozone generator 270 flows to the adsorbent 280, allowing the ozone to fully contact the adsorbent 280, thereby increasing the adsorption effect of the adsorbent 280 on ozone.

[0132] The refrigerator compartment 101 described above has a good deoxygenation effect and a simple overall structure that is easy to arrange.
