[0022] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Refrigerators can keep food warm, fresh or frozen. In order to improve the preservation quality of food, some refrigerators in the related art are equipped with devices for sterilizing and deodorizing food. However, the sterilizing and deodorizing devices used in the related art are relatively complex in structure, with high installation costs and the effect on food needs to be improved.

[0027] To solve the above problems, Figure 1 The present application provides a refrigerator 100 , which includes a box body 30 , a refrigeration system and an ion generating unit 22 .

[0028] The box body 30 adopts a rectangular hollow structure, and the box body 30 is configured as the outer shell of the refrigerator 100. It is understandable that the box body 30 can also adopt a hollow shell structure of other shapes. A plurality of mutually separated refrigeration chambers 312 can be arranged in the box body 30, and each of the separated refrigeration chambers 312 can be used as an independent storage space, such as a freezer, a refrigerator, an ice chamber, a variable temperature chamber, etc., to meet different refrigeration requirements such as freezing, refrigeration and variable temperature according to different types of food, and store them. The plurality of refrigeration chambers 312 can be arranged in a vertical partition, or in a left-right partition.

[0029] The box body 30 includes a box shell and an inner liner 31 disposed in the box shell. A refrigeration compartment 312 is formed in the inner liner 31. It should be noted that a plurality of inner liner 31 may be provided. Only one refrigeration compartment 312 may be provided in the same inner liner 31, or a plurality of refrigeration compartments 312 may be provided.

[0030] The box body 30 further includes a door 32 disposed at the front side of the box shell. The door 32 is used to open and close the refrigeration compartment 312. The door 32 and the box shell may be connected by a hinge, so that the door 32 of the refrigerator 100 can rotate around the axis of the hinge to open and close the door 32, thereby opening and closing the corresponding refrigeration compartment 312. It is understandable that a plurality of doors 32 may be provided, and are provided one-to-one with the refrigeration compartment 312. Alternatively, a plurality of doors 32 may open and close a refrigeration compartment 312 at the same time.

[0031] The refrigeration system is used to provide cold air to the inner tank 31, thereby realizing functions such as freezing and refrigeration. The refrigeration system mainly includes a compressor, a condenser, and an evaporator, and refrigeration is performed by circulating a refrigerant between the compressor, the condenser, and the evaporator. An air supply duct 101 connected to the refrigeration compartment 312 is also provided in the box body 30, and the air supply duct 101 is used to transport cold air to the refrigeration compartment 312. Among them, the air supply duct 101 can be formed by the inner tank 31 or the inner tank 31 and the box shell, or it can be formed by setting a structure such as an air guide plate on the inner tank 31 or the box shell, or part or all of the air supply duct 101 can also be in the form of a pipeline, which is not limited in the embodiment of the present application. The refrigeration compartment 312 is provided with an air inlet 14, and the air supply duct 101 is connected to the air inlet 14 to deliver cold air to the refrigeration compartment 312 through the air inlet 14. For example, the air inlet 14 is directly disposed on the inner container 31 , or the air inlet 14 may also be disposed on other structures located in the refrigeration compartment 312 , such as the shelf 33 , the drawer device 10 , and the like.

[0032] Please combine Figure 1 and Figure 2 In the embodiment of the present application, the ion generating unit 22 is arranged at the air inlet 14. The ion generating unit 22 can discharge and ionize the molecules in the air to form charged particles, negative ions and other microparticles. These charged particles can combine with microorganisms to settle or disrupt the surface potential of microorganisms, thereby causing the death of microorganisms and extending the shelf life of food. Exemplarily, the ion generating unit 22 includes a linear or needle-shaped electrode. After being connected to a power source, the electrode of the ion generating unit 22 discharges and ionizes the air molecules to form ions at the air inlet 14.

[0033] In the embodiment of the present application, the ion generating unit 22 partially blocks the air inlet 14. It can be understood that when the ion generating unit 22 is provided, the airflow can still flow through the portion of the air inlet 14 that is not blocked by the ion generating unit 22. Therefore, when the refrigerator 100 is refrigerating, the cold air flows from the air supply duct 101 through the air inlet 14 to the refrigeration compartment 312, and the ions generated by the ion generating unit 22 ionizing the air move into the refrigeration compartment 312 under the drive of the airflow flowing in from the air inlet 14, and act on the surface of the food to sterilize and preserve the food.

[0034] In this way, by setting the ion generating unit 22 at the air inlet 14 of the refrigerating chamber 312 of the refrigerator 100, the ions generated by the ion generating unit 22 act on the food along with the airflow flowing in from the air inlet 14, which can kill the microorganisms, sterilize the food and ensure the preservation of the food. In addition, the charged particles can also absorb the suspended particles in the air and make them settle by their own adsorption and sedimentation, purify the air, and reduce the possibility of secondary contamination of the food.

[0035] On the one hand, the ion generating unit 22 partially blocks the air inlet 14. In this way, under the premise of reducing or avoiding the influence on the air intake of the air inlet 14, the ions generated by the ion generating unit 22 ionizing the air can move and act on the food while the cold air entering from the air inlet provides cooling for the refrigeration chamber 312, thereby ensuring the effect of the ion generating unit 22. On the other hand, the cold air flowing into the air inlet 14 not only provides cooling for the refrigeration chamber 312, but also provides power for the movement of the ions ionized by the ion generating unit 22, thereby realizing the integration of the functions of the refrigerator 100. In this way, there is no need to set up a separate air duct component for the ion generating unit 22 to supply air to drive the movement of ions, which can reduce the number of parts, make the structure of the refrigerator 100 simpler and more compact, improve space utilization and reduce costs. At the same time, since the structure of the ion generating unit 22 in the refrigerator 100 is simplified, it is beneficial to make the ion generating unit 22 closer to the food in the refrigeration chamber 312, and the ions generated by the ion generating unit 22 ionizing the air are also closer to the food. Therefore, when the ion wind blows into the refrigeration chamber 312, more ions can act on the food more evenly, thereby improving the effect of the ion generating unit 22 and improving the preservation quality of the food.

[0036] like Figure 2 As shown, in some embodiments, the ion generating unit 22 is formed as a linear electrode. When the linear electrode is powered on, it can ionize the air to generate ions, and it also has the advantages of being small in size and easy to manufacture, and can ensure that the generated ions are more uniform. The linear electrode has a small area to block the air inlet 14, which can reduce the impact on the airflow at the air inlet 14, ensuring that the refrigeration compartment 312 can obtain the required cooling capacity. At the same time, the linear electrode also enables the airflow at the air inlet 14 to better surround the ion generating unit 22, thereby effectively driving the movement of ions and forming ion wind. Further, the ion generating unit 22 includes a plurality of linear electrodes, and the plurality of linear electrodes are arranged at intervals at the air inlet 14. Among them, an air inlet gap is defined between two adjacent linear electrodes or between the linear electrode and the wall of the air inlet 14, and the air inlet gap is connected to the air supply duct, so that the airflow of the air supply duct flows into the refrigeration compartment 312 through the air inlet gap. In this way, the ion generating unit 22 can generate sufficient ions, improve the uniformity of ion distribution and ensure the permeability of airflow at the ion generating unit 22, so as to fully sterilize and preserve the food, thereby improving the preservation effect of the food. Optionally, a plurality of linear electrodes are arranged in parallel to further improve the uniformity of ions generated by the ion generating unit 22 ionizing the air, and can reduce the disturbance of the airflow, thereby improving the effect of the ion generating unit 22.

[0037] In some embodiments of the present application, the refrigeration compartment 312 may be provided with a plurality of air inlets 14, and the plurality of air inlets 14 are arranged at intervals. The plurality of air inlets 14 may be arranged on the same inner wall or on different inner walls of the refrigeration compartment 312, and correspondingly, at least one of the air inlets 14 is provided with an ion generating unit 22. When a plurality of ion generating units 22 are provided, the plurality of ion generating units 22 may be arranged on one inner wall or multiple inner walls of the refrigeration compartment 312 according to the arrangement of the air inlets 14.

[0038] In some embodiments, the refrigerator 100 can keep food such as meat warm and fresh by designing a drawer device 10 to form a relatively independent storage cavity 131. The drawer device 10 is arranged in the refrigeration compartment 312, and includes a slidable drawer 13. Food can be stored in the drawer 13, and when the drawer 13 is pulled out, the food can be taken out or other food can be put into the drawer 13. In these schemes, the air supply duct 101 is jointly defined by the inner liner 31 and the drawer device 10, and the inner liner 31 is also provided with a return air port of the air supply duct 101. The drawer device 10 has an air inlet 14 and an air outlet, wherein the air inlet 14 is connected to the air supply duct 101, and the air outlet is connected to the return air port. In this way, the refrigeration system transports cold air to the drawer device 10 through the air supply duct 101 and the air inlet 14, and performs heat exchange with the food in the drawer device 10 to cool the food. The air after heat exchange returns to the air supply duct 101 or is discharged to the outside through the exhaust port and the return air port.

[0039] Optionally, the air supply duct 101 includes a compartment duct 311 and a drawer duct 17 that are connected, the inner liner 31 defines the compartment duct 311, and the drawer device 10 defines the drawer duct 17. Exemplarily, the inner liner 31 can divide its internal space into a compartment duct 311 and a refrigeration compartment 312 by a partition, and the compartment duct 311 is optionally located on the back side, left and right sides, or top side of the refrigeration compartment 312.

[0040] Combination Figures 2 to 5 In a specific embodiment of the present application, the drawer device 10 includes a cabinet 11 and a drawer 13 .

[0041] The cabinet 11 is arranged in the refrigeration chamber 312, and the cabinet 11 encloses a receiving cavity 111 with an opening on the front side. Specifically, the cabinet 11 includes two side panels 112 arranged opposite to each other in the left-right direction, a top panel 113 and a bottom panel 114 arranged opposite to each other in the up-down direction, and a back panel 115 covering the rear sides of the side panels 112, the top panel 113, and the bottom panel 114. Thus, the two side panels 112, the top panel 113, the bottom panel 114, and the back panel 115 enclose the receiving cavity 111 together, and the front sides of the two side panels 112, the top panel 113, and the bottom panel 114 together define an opening. It should be noted that each of the side panels 112, top panels 113, bottom panels 114, and back panels 115 can be a single panel, or multiple panels, such as a double-layer panel or a multi-layer panel structure, and the panels in the side panels 112, top panels 113, bottom panels 114, and back panels 115 can be split structures that are then spliced, or can be a module formed by a whole large panel through processes such as bending and cutting, but the module has different panel parts corresponding to the side panels 112, top panels 113, bottom panels 114, and back panels 115, or the different panel parts corresponding to the side panels 112, top panels 113, bottom panels 114, and back panels 115 can be formed into an integral module through casting, and this application does not limit this. In addition, the material of the panel of the above structure can be plastic or metal. When the material is metal, it can be aluminum alloy, iron alloy, and other materials.

[0042] It should be noted here that the left and right directions can be understood as the directions corresponding to the left and right sides of the user when the user stands facing the refrigerator 100 directly in front of the refrigerator 100, the front and back directions can be understood as the direction in which the drawer 13 enters and exits the cabinet 11, and the up and down directions are perpendicular to the left and right directions and the front and back directions.

[0043] The drawer 13 can be pulled out and accommodated in the accommodating cavity 111, and includes a main body 132 and an end cover 133 connected to the front side of the main body 132. The main body 132 is slidably connected to the cabinet 11 and can be accommodated in the accommodating cavity 111, and the end cover 133 can cover the opening. Among them, a storage cavity 131 opened upward is formed on the main body 132 to hold food, and a sliding guide 15 can be provided between the outer wall of the main body 132 opposite to the cavity wall of the accommodating cavity 111 in the left and right directions, and the main body 132 and the cabinet 11 are slidably connected by the sliding guide 15.

[0044] In this embodiment, the cabinet 11 is formed with a drawer air duct 17 and an air inlet 14. The drawer air duct 17 is connected to the compartment air duct 311 for conveying cold air. For example, the cabinet 11 is provided with a connecting port for connecting the drawer 13 air and the compartment air duct 311. Optionally, the connecting port can be opened on the back plate 115, so that it is easy to dock with the air outlet on the wall of the inner tank 31 of the refrigerator 100 at the rear side of the cabinet 11. The air inlet 14 can be set on at least one of the two side plates 112, the top plate 113, the bottom plate 114 and the back plate 115, and connect the drawer air duct 17 and the accommodating chamber 111, so that cold air can enter the accommodating chamber 111 from the drawer air duct 17 through the air inlet 14. Since the drawer 13 can be accommodated in the accommodating chamber 111, the air inlet 14 is also connected to the storage chamber 131, so that cold air can enter the storage chamber 131 and act on the food. The ion generating unit 22 is connected to the cabinet 11, and specifically can be connected to at least one of the two side panels 112, the top panel 113, the bottom panel 114 and the back panel 115, and is arranged corresponding to the air inlet 14. In this way, the cold air delivered to the air inlet 14 through the compartment air duct 311 and the drawer air duct 17 can form ion wind flowing into the storage cavity 131. Since the storage cavity 131 is closed by the cabinet 11 and the drawer 13, it is suitable for preserving some meat ingredients, etc., and the ion wind can be easily and evenly distributed in the storage cavity 131, fully sterilizing and disinfecting the ingredients in the drawer device 10, and improving the preservation effect of the ingredients.

[0045] Alternatively, if Figures 2 to 4 As shown, the air inlet 14 is located on the top wall of the accommodating chamber 111, that is, the top plate 113, the drawer 13 is arranged to open toward the top wall of the accommodating chamber 111, and the ion generating unit 22 is connected to the top wall of the accommodating chamber 111. Since the top of the storage chamber 131 of the drawer 13 opens toward the top wall of the accommodating chamber 111, the top wall of the accommodating chamber 111 can be exposed in the storage chamber 131, and the air inlet 14 arranged in the accommodating chamber 111 is connected to the storage chamber 131. In combination with the above content, the drawer air duct 17 of this embodiment can be arranged in the top plate 113, that is, the top plate 113 can be composed of at least two layers of plates arranged at intervals in the up and down directions, wherein the drawer air duct 17 is formed between the two layers of plates, and the air inlet 14 is opened on the plate located at the bottom layer of the top plate 113, that is, located on the cavity top wall of the accommodating chamber 111. That is to say, the drawer device 10 of the present embodiment adopts a top air intake method relative to the storage cavity 131 in the drawer 13, and because the storage cavity 131 has an opening toward the top wall of the accommodating cavity 111, cold air can enter the storage cavity 131 unimpeded, which not only makes the airflow smoother, but also reduces the loss of ions, so that the ions generated by the ion generating unit 22 can act more directly on the food, and also avoids additional opening design for the drawer 13, thereby ensuring the good storage performance of the drawer 13.

[0046] Furthermore, the air inlet 14 is arranged in the middle of the top wall of the accommodating cavity 111, and the cold air flowing from the air inlet 14 to the storage cavity 131 can be blown toward the food evenly in all directions, thereby covering the food and reducing dead corners. The ion distribution can also be more uniform, thereby improving the effect of the ion generating unit 22.

[0047] Specifically, combined Figure 4 , the top plate 113 includes two layers of structural plates 1131 and a heat-insulating layer 1132. The structural plates 1131 can be made of plastic material, and the heat-insulating layer 1132 can be made of foam material or the like. The two layers of structural plates 1131 are arranged in the up and down directions for structural support, and the heat-insulating layer 1132 is sandwiched between the two layers of structural plates 1131 for heat preservation. Among them, the drawer air duct 17 is formed between the two layers of structural plates 1131. The structural plate 1131 located below forms the top wall of the accommodating cavity 111, and the air inlet 14 is arranged on the structural plate 1131 located below. The heat-insulating layer 1132 is located on the side of the structural plate 1131 located below away from the accommodating cavity 111, and a avoidance hole is provided for the air inlet 14 to allow cold air to flow to the air inlet 14 through the avoidance hole. The ion generating unit 22 is embedded in the heat-insulating layer 1132 and is located at the avoidance hole. The ion generating unit 22 is disposed inside the top plate 113 so that the ion generating unit 22 is disposed close to the air inlet 14 , while reducing the occupation of the internal space of the storage cavity 131 and protecting the ion generating unit 22 from structural damage.

[0048] Of course, in some structures, the bottom of the drawer 13, that is, the side opposite to the end cover 133, is also provided with an opening. In these structures, the air inlet 14 can also be opened on the bottom wall of the accommodating cavity 111, that is, opened on the bottom plate 114, so that the ion generating unit 22 can also be arranged on the bottom wall of the accommodating cavity 111, which will not be elaborated here.

[0049] Combination Figure 2 and Figure 5In another specific embodiment of the present application, the drawer device 10 includes a partition 12 and a drawer 13. The partition 12 is arranged in the refrigeration chamber 312, and separates the refrigeration chamber 312 into an ice chamber. The partition 12 is connected to the wall of the inner liner 31, and the ice chamber is formed by the inner liner 31 and the partition 12. It can be understood that the partition 12 can be in the form of a multi-layer plate body. For example, the partition 12 is formed by stacking two plates, and a drawer air duct 17 is formed inside the partition 12. The drawer 13 is pullable and arranged in the ice chamber, and the partition 12 is located above the drawer 13. The drawer 13 includes a main body 132 and an end cover 133 connected to the front side of the main body 132, and forms an upwardly open storage cavity 131 for holding food. Furthermore, the refrigerator 100 may also include a sealing strip 16, which may be installed on the front side of the partition 12 or on the end cover 133 of the drawer 13. After the drawer 13 enters the ice chamber, the sealing strip 16 is clamped between the front side of the partition 12 and the end cover 133, thereby achieving sealing between the panel and the front side of the end cover 133. The partition 12 is provided with an air inlet 14, which is connected to the drawer air duct 17 and the storage cavity 131, and the ion generating unit 22 is connected to the partition 12 to generate ion wind flowing to the storage cavity 131.

[0050] Of course, in other embodiments of the present application, there is also a structural form in which the drawer 13 is provided with an air inlet 14, and the ion generating unit 22 is installed on the drawer 13. It can be understood that in the above embodiment in which the ion generating unit 22 is installed on the cabinet 11 or the partition 12, there is no need to make an additional opening on the drawer 13 for airflow to pass through, which simplifies the structure of the drawer 13 and ensures that the drawer 13 can store food well.

[0051] Please refer to Figure 1In some other embodiments, the box body 30 further includes a shelf 33 disposed in the refrigeration compartment 312, the shelf 33 is optionally connected to the inner liner 31, and the refrigeration compartment 312 is divided into a plurality of spaces, so that the user can store food efficiently. Among them, the shelf 33 can be made of a single-layer material such as glass, and is disposed in the refrigeration compartment 312 in a manner parallel to the ground, the inner liner 31 is provided with an air inlet 14, and the ion generating unit 22 is connected to the inner liner 31. For example, the air inlet 14 is disposed on the top wall of the refrigeration compartment 312 or the rear side wall opposite to the front opening of the refrigeration compartment 312, and the ion generating unit 22 is also correspondingly connected to the top wall or the rear side wall of the refrigeration compartment 312. Optionally, along the direction from the inside to the outside of the refrigeration compartment 312, the inner liner 31 includes a plastic layer for protection and support and a foaming layer for heat preservation, and the ion generating unit 22 can be disposed outside the foaming layer or between the foaming layer and the plastic layer, or embedded in the foaming layer. Of course, the shelf 33 can also be made of a multi-layer board. In this solution, the air inlet 14 can also be set on the shelf 33, and the ion generating unit 22 can be set in the interlayer of the shelf 33. In this way, the air inlet 14 can deliver cold air to the space around the shelf 33, and the ions generated by the ion generating unit 22 can also sterilize the food on the shelf 33, thereby improving the preservation quality of the food.

[0052] Of course, under the premise of ensuring that the ion generating unit 22 can generate ion wind to sterilize and preserve the food in the refrigeration chamber 312, the present application does not limit the structural setting form in the refrigeration chamber 312. For example, the box body 30 may not be provided with the shelf 33, and the food can be directly stored in the inner tank 31.
