When a feature "includes or contains" one or some of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

[0041] In the description of the present embodiment, the description with reference to the terms "one embodiment", "some embodiments", "some examples", "an example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0042] The utility model provides a refrigerator 10, Figure 1 is a schematic structural diagram of a refrigerator 10 according to an embodiment of the present utility model, as shown in Figure 1 As shown, the refrigerator 10 may generally include a cabinet 110 and a door 120 .

[0043] Among them, one or more storage compartments are formed inside the box 110, and the storage compartments can be configured as a refrigeration compartment 111, a freezing compartment 112, a variable temperature compartment, etc. according to the refrigeration temperature. Specifically, the function, quantity and layout of the storage compartments can be configured according to actual needs.

[0044] The door body 120 may be a single-opening door or a double-opening door. The door body 120 is correspondingly arranged at the front side of each storage compartment and is pivotally connected to the box body 110 for controlled opening or closing of the storage compartment.

[0045] The refrigerator 10 may further include a fresh-keeping device 20. Figure 2 is a schematic perspective view of a fresh-keeping device 20 according to an embodiment of the present invention, referring to Figure 2 The fresh-keeping device 20 may include a fresh-keeping container 210 , a shelf 220 and a sterilization module 240 .

[0046] A fresh-keeping space 213 is formed in the fresh-keeping container 210. The fresh-keeping space 213 may be a relatively closed space, and the internal temperature and humidity thereof may be manually adjusted to provide suitable temperature and humidity conditions for the storage of food.

[0047] The shelf 220 can be arranged in the fresh-keeping space 213, and the shelf 220 has a plurality of food trays 224, and each food tray 224 can be used to place food to be preserved. The food to be preserved can be of the same type or of different types.

[0048] The sterilization module 240 may be disposed above the shelf 220 , and the sterilization module 240 is used to release sterilization substances in a controlled manner to purify the fresh-keeping space 213 using the sterilization substances.

[0049] In the fresh-keeping device 20 of the present invention, since the sterilization module 240 can release sterilizing substances, the sterilizing substances can be used to purify the fresh-keeping space 213, inhibit the growth of bacteria in the fresh-keeping space 213, reduce the risk of food spoilage, thereby improving the fresh-keeping quality of the food and extending the fresh-keeping time of the food.

[0050] In some optional embodiments, the fresh-keeping container 210 can be arranged in the storage compartment of the refrigerator 10, or can be arranged outside the body 110 of the refrigerator 10, or can be embedded in the body 110 of the refrigerator 10 as an independent compartment.

[0051] In one example, the fresh-keeping container 210 is a drawer-type container, which includes a drawer sleeve 212 and a drawer body 211. The drawer sleeve 212 has a side opening, and the drawer body 211 has a top opening. The drawer body 211 can be pushed and pulled in the drawer sleeve 212 through the side opening, and together with the drawer sleeve 212, defines the above-mentioned fresh-keeping space 213.

[0052] That is to say, the fresh-keeping container 210 serves as an independent compartment of the refrigerator 10, and its drawer sleeve 212 is embedded in the box body 110, which can serve as the fresh-keeping liner of the box body 110. When the user takes and puts food, the operation can be made more convenient by pushing and pulling the drawer body 211.

[0053] In a typical example, refer to Figure 1 The upper area of ​​the box body 110 can form a refrigerating compartment 111, and the lower area can form a freezing compartment 112. The number of the preservation devices 20 can be two, and the preservation containers 210 of the two preservation devices 20 are arranged side by side between the refrigerating compartment 111 and the freezing compartment 112.

[0054] Figure 3 is a schematic assembly diagram of a drawer body 211 and a shelf 220 according to an embodiment of the present invention, referring to Figure 3 The shelf 220 can be used as a drawer cover plate to buckle the top opening of the drawer body 211. In this way, the distance between the shelf 220 and the sterilization module 240 can be shortened, so that the sterilization substance released by the sterilization module 240 can directly act on the food on the shelf 220, thereby improving the sterilization effect of the sterilization module 240.

[0055] In actual application, the exposed food can be placed in the food tray 224 of the shelf 220. Since the exposed food will come into contact with the air in the fresh-keeping space 213, there is a problem of bacterial growth, so the sterilization module 240 can be used to sterilize it regularly.

[0056] In addition, when the shelf 220 is buckled onto the drawer body 211 as a drawer cover, a mezzanine space is formed between the shelf 220 and the bottom wall of the drawer body 211, and sealed food can be placed in the mezzanine space. Since the sealed food usually has a fresh-keeping bag / film, it will not come into contact with the air in the fresh-keeping space 213 and usually does not require sterilization. Placing it in the mezzanine space can also prevent it from being squeezed and damaged.

[0057] In an optional embodiment, the shelf 220 may have a folding function. After being folded, the shelf 220 will no longer be used as a drawer cover, but will be offset as a whole to one side of the drawer body 211, thereby leaving space on the other side of the drawer body 211 for storing other ingredients.

[0058] Figure 5 is a schematic diagram of a folded shelf 220 according to an embodiment of the utility model. Figure 6 is a schematic diagram of a folded shelf 220 according to another embodiment of the present invention. Figure 5 and Figure 6 As shown, the shelf 220 may include a set of shelf plates 221, and the set of shelf plates 221 may include a plurality of shelf plates 221 arranged flat, and each shelf plate 221 has a plurality of food holders 224. The plurality of shelf plates 221 may be hinged in sequence, and each shelf plate 221 may be folded around its hinge to another shelf plate 221, so that the food holders 224 of the two shelf plates 221 are buckled up and down to accommodate food.

[0059] In this way, each shelf board 221 can be flexibly flipped. When there are fewer ingredients placed on the shelf 220, the idle shelf boards 221 in the shelf 220 can be folded and stored, thereby reducing the space occupied by the shelf 220 so that more ingredients can be accommodated in the fresh-keeping space 213, thereby improving the utilization rate of the fresh-keeping space 213.

[0060] like Figure 5 As shown, if only one shelf 221 in the shelf 221 group is in an idle state, only the shelf 221 can be folded upward. Figure 6 As shown, if two of the shelf plates 221 are in an idle state, the two shelf plates 221 can be folded upward at the same time. In this way, a certain space can be reserved on one side of the shelf 220 to store other food materials.

[0061] Each shelf 221 can extend along the front-to-back direction of the drawer body 211, and multiple shelf plates 221 are sequentially arranged along the left-right direction of the drawer body 211. Of course, in other examples, each shelf 221 can also extend along the left-right direction of the drawer body 211, and multiple shelf plates 221 are sequentially arranged along the front-to-back direction of the drawer body 211.

[0062] Figure 7 is a schematic top view of a drawer body 211 and a shelf 220 according to another embodiment of the utility model. Figure 8 yes Figure 7 Schematic cross-sectional view along the AA direction, Fig. 9 yes Figure 7 Schematic cross-sectional view along the BB direction, refer to Figures 7 to 9 The shelf 220 may further include two first limit plates 222, which are arranged on the left and right sides of the shelf plate 221 group. When the shelf 220 is buckled on the top opening of the drawer body 211, the two first limit plates extend downward to the outer side of the left and right walls of the drawer body 211, respectively, to limit the shelf plate 221 group to the left and right sides.

[0063] That is to say, the distance between the two first limit plates 222 is slightly larger than the width of the drawer body 211. In this way, when the shelf 220 is snapped into the top opening of the drawer body 211, the two first limit plates 222 are equivalent to clamping the drawer body 211 from the left and right sides of the drawer body 211, thereby preventing the shelf plate 221 group from shaking left and right relative to the drawer body 211 during the process of pushing and pulling the drawer body 211.

[0064] Furthermore, the shelf 220 may also include at least two second limiting plates 223, which are arranged on the front and rear sides of the shelf plate 221 group, and when the shelf 220 is snapped into the top opening of the drawer body 211, they extend downward to the inner side of the front side wall and the inner side of the rear side wall of the drawer body 211 respectively, so as to limit the shelf plate 221 group front and rear.

[0065] That is to say, the distance between the two second limit plates 223 is slightly smaller than the length of the drawer body 211. In this way, when the shelf 220 is snapped into the top opening of the drawer body 211, the two second limit plates 223 can extend into the drawer body 211. In the process of pushing and pulling the drawer body 211, the shelf 220 is prevented from accidentally slipping off from the front and rear directions of the drawer body 211 as a whole by abutting against the inner side of the front side wall of the drawer body 211, or the inner side of the rear side wall.

[0066] In an optional embodiment, adjacent shelves 221 may be hinged by one or more hinges. The hinges may have a stop function, that is, they limit the relative rotation between the two shelves 221 in a locked state, and allow the relative rotation between the two shelves 221 in an unlocked state. In this way, when the shelf 220 is buckled into the top opening of the drawer body 211 as a drawer cover, the shelves 221 can be prevented from rotating and sinking due to their own weight and the weight of the food, which is conducive to maintaining the horizontal expansion state of each shelf 221.

[0067] Considering that the manufacturing cost of the above-mentioned hinge with a stop function is relatively high, in order to save manufacturing costs, only ordinary hinges 229 are used as hinges in this embodiment.

[0068] In an optional embodiment, a second limiting plate 223 is formed on both the front and rear sides of each shelf 221, and a limiting slot 225 for accommodating the left or right wall of the drawer body 211 is formed between the first limiting plate 222 and the adjacent second limiting plate 223.

[0069] For the first limiting plate 222 on the left or right side, there is the above-mentioned limiting slot 225 between it and the two adjacent front and rear second limiting plates 223. When the shelf 220 is buckled into the top opening of the drawer body 211 as a drawer cover, the limiting slot 225 can clamp the left and right walls of the drawer body 211, so as to limit the overall width of the shelf plate 221 group, thereby preventing the shelf plate 221 group from rotating and sinking due to its own weight and the weight of the food.

[0070] The left side wall and the right side wall of the drawer body 211 can be gradually tilted inward from top to bottom, so that the drawer body 211 is gradually contracted from top to bottom. The side wall of the limit slot 225 located in the drawer body 211 (i.e., the side of the second limit plate 223 adjacent to the limit slot 225) can be gradually tilted and extended inward from top to bottom, and its tilt angle is consistent with the tilt angle of the left side wall or the right side wall of the drawer body 211.

[0071] In this way, when the shelf 220 is buckled into the top opening of the drawer body 211 as a drawer cover, the side wall of the limit slot 225 located in the drawer body 211 can be supported on the left wall or the right wall of the drawer body 211, so that the multiple shelves 221 can better carry the food and will not rotate and sink due to the uneven weight distribution of the food.

[0072] The upper edges of the left and right walls of the drawer body 211 can be gradually extended upward from the back to the front. In this way, when the drawer body 211 is pulled out, the sinking amount of the drawer body 211 can be compensated, so that the shelf 220 is in a horizontal state as a whole, which is more conducive to taking and placing food to a certain extent.

[0073] Since each shelf 221 has a second limiting plate 223 on both the front and rear sides, the length of the second limiting plate 223 can be set greater than the depth of the food tray 224, so that the shelf 221 can be stably supported on the bottom wall of the drawer body 211 by the two front and rear second limiting plates 223.

[0074] Fig.10 is a schematic cross-sectional view of a food tray 224 according to an embodiment of the present invention, referring to Fig.10The food tray 224 can be formed by the top of the shelf plate 221 being recessed downward, that is, the food tray 224 and the shelf plate 221 are formed in one piece. This formation method can improve the connection stability between the food tray 224 and the shelf plate 221, reduce the problem of breakage between the food tray 224 and the shelf plate 221, and extend the service life of the food tray 224.

[0075] The interior of the food support 224 may be in the shape of an arc groove, and its specific size may be designed specifically according to the food that needs to be kept fresh. In this way, when supporting spherical or quasi-spherical food, the food can be prevented from rolling freely and damaged due to collision.

[0076] A buffer washer 226 surrounding the food tray 224 may be provided on the top of the shelf 221. The buffer washer 226 may be a soft rubber ring, and the lower edge of the buffer washer 226 may be smoothly connected to the upper edge of the food tray 224. The buffer washer 226 may prevent the upper edge of the food tray 224 from hitting the food and causing the food to break, thereby ensuring safe storage of the food.

[0077] The bottom of the food tray 224 may be provided with a downwardly penetrating air hole 227. The air hole 227 can allow the food to breathe, prevent the food from being partially deprived of oxygen and necrosis, and is conducive to improving the freshness of the food.

[0078] Furthermore, a water-absorbing gasket 228 surrounding the air hole 227 may be provided at the bottom of the food tray 224, and the water-absorbing gasket 228 may be bonded to the inner wall of the food tray 224. Since the preservation temperature of food is usually low, in some cases, condensation water may adhere to the surface of the food. By absorbing the condensation water by the additional water-absorbing gasket 228, the surface of the food can be kept dry, the growth of bacteria can be reduced, and the preservation quality of the food can be improved.

[0079] In an optional embodiment, the sterilization module 240 may include a shell and an electrode group, wherein the shell is in the shape of a box, the interior of the shell defines a cavity, the electrode group is arranged in the cavity, and the electrode group includes an excitation electrode and a receiving electrode, and the excitation electrode and the receiving electrode are arranged at intervals. The excitation electrode is used to generate high-energy electrons, and the high-energy electrons can move in a directional manner under the action of the electric field and collide with air molecules, thereby generating an ion wind blowing toward the side of the receiving electrode. In the process of directional movement, the electrons can break up odor molecules, excite oxygen to produce ozone, and the excitation electrode can break down the cells of suspended organisms through high-voltage ionization discharge, thereby achieving sterilization and deodorization of the fresh-keeping space 213.

[0080] Of course, the above examples of the sterilization module 240 are merely illustrative, and those skilled in the art should be able to easily change the type of the sterilization module 240 based on the understanding of the above embodiments, and these changes should all fall within the protection scope of the present utility model.

[0081] In one example, the sterilization module 240 can be disposed on the lower surface of the top wall of the drawer sleeve 212. In this way, the sterilization substance produced by the sterilization module 240 can be directly supplied to the fresh-keeping room.

[0082] In another example, referring to Fig.11 The top wall of the drawer sleeve 212 is formed with an upwardly recessed mounting groove 214, and the sterilization module 240 is arranged in the mounting groove 214. In this way, the sterilization module 240 can be prevented from occupying the fresh-keeping space 213, which is conducive to improving the space utilization rate of the fresh-keeping space 213, so that the fresh-keeping space 213 can accommodate more food.

[0083] Furthermore, a mounting cover 215 may be provided on the top wall of the drawer sleeve 212 , and the shape of the mounting cover 215 is adapted to the shape of the notch of the mounting groove 214 , and the mounting cover 215 covers the notch of the mounting groove 214 to achieve concealed installation of the sterilization module 240 .

[0084] The mounting cover 215 is provided with sterilization holes 216 that allow sterilization substances to flow out, and the number of sterilization holes 216 can be multiple, evenly distributed on the surface of the mounting cover 215. The sterilization holes 216 can be one or more of circular holes, square holes, prismatic holes, and elliptical holes, and the utility model is not limited to this.

[0085] In an optional embodiment, the top wall of the drawer sleeve 212 is provided with an air inlet 201 and an air return port 202, wherein the air inlet 201 is mainly used to introduce cooling air into the fresh-keeping space 213, so as to use the cooling air to adjust the internal temperature of the fresh-keeping space 213. The air return port 202 is mainly used to exhaust the air in the fresh-keeping space 213, so that the cooling air can be continuously delivered to the fresh-keeping space 213.

[0086] In one example, the return air port 202 may be located on both sides of the air inlet 201, and the sterilization module 240 may be disposed adjacent to the air inlet 201. In this way, the sterilization substance generated by the sterilization module 240 may be mixed with the refrigeration airflow, and the refrigeration airflow may distribute the sterilization substance more evenly to each area of ​​the fresh-keeping space 213 during the flow process, thereby achieving comprehensive sterilization of the fresh-keeping space 213.

[0087] In an optional embodiment, a light bar 217 for lighting the fresh-keeping space 213 may be provided in the fresh-keeping container 210. For example, when the drawer body 211 is pulled outward, the light bar 217 automatically lights up, which is beneficial for users to take and put food at night.

[0088] The top wall of the drawer sleeve 212 may be provided with a light groove 218, in which the light bar 217 may be mounted, and a transparent cover plate 219 covering the light groove 218 may be provided. In this way, the light bar 217 may be sealed in the light groove 218 by the transparent cover plate 219, which may effectively reduce damage to the light bar 217.

[0089] In one example, the light slot 218 is opened on the installation cover 215, and the transparent cover 219 covers the notch of the light slot 218. The lower surface of the transparent cover 219 can be flush with the lower surface of the installation cover 215 and the lower surface of the top wall of the drawer sleeve 212.

[0090] In an optional embodiment, the fresh-keeping device 20 may further include an electrolytic deoxidation device 230, which may be disposed in the fresh-keeping space 213, or an installation port may be provided on the wall of the fresh-keeping space 213, and the electrolytic deoxidation device 230 may be snapped into the installation port. The electrolytic deoxidation device 230 is mainly used to remove part of the oxygen in the fresh-keeping space 213, so that a low-oxygen atmosphere is formed in the fresh-keeping space 213. For some egg ingredients, fruit and vegetable ingredients, the low-oxygen atmosphere can inhibit the respiration of the ingredients, reduce the classification of organic matter in the ingredients, improve the fresh-keeping quality of the ingredients, and extend the fresh-keeping time.

[0091] Fig.12 is a schematic structural diagram of an electrolytic deoxidation device 230 according to an embodiment of the utility model. Fig.13 is a schematic diagram of an electrolytic deoxidation device 230 according to an embodiment of the present invention, referring to Fig.12 and Fig.13 The electrolytic deoxidation device may include a shell 231 , a cathode plate 233 and an anode plate 234 .

[0092] The shell 231 is roughly in the shape of a flat rectangular parallelepiped, and the side wall with the largest area (such as the bottom wall) of the shell 231 can be opened to form a connecting port 232, which is beneficial to increase the contact area between the cathode plate 233 of the electrolytic deoxidation device 230 and the fresh-keeping space 213.

[0093] The cathode plate 233 is disposed at the connecting port 232 to define together with the shell 231 a liquid storage chamber 235 for containing electrolyte, and is used to consume oxygen in the fresh-keeping space 213 through electrochemical reaction under the action of the electrolysis voltage. The cathode plate 233 is disposed at the connecting port 232, and the cathode plate 233 has a waterproof and breathable function (such as a waterproof and breathable membrane). While closing the liquid storage chamber 235, the cathode plate 233 can ensure that the airflow is connected to the fresh-keeping space 213. For example, the oxygen in the fresh-keeping space 213 can undergo a reduction reaction at the cathode plate 233, that is: O2+2H2O+4e-→4OH-. The electrolyte contained in the liquid storage chamber 235 can be an acidic aqueous solution or an alkaline aqueous solution, for example, a 1-5 mol / L sodium hydroxide solution.

[0094] The anode plate 234 is disposed in the liquid storage chamber 235 and is used to provide reactants to the cathode plate 233 through an electrochemical reaction. The anode plate 234 and the cathode plate 233 are disposed in the liquid storage chamber 235 at intervals from each other. When powered, the anode plate 234 is used to provide reactants (e.g., electrons) to the cathode plate 233 through an electrochemical reaction and generate oxygen. For another example, the OH- generated by the cathode plate 233 can undergo an oxidation reaction at the anode plate 234 and generate oxygen, that is: 4OH-→O2+2H2O+4e-. An exhaust port 239 can also be provided on the housing 231 (e.g., the top wall), and oxygen can be discharged through the exhaust port 239.

[0095] The above examples of electrochemical reactions of the anode plate 234 and the cathode plate 233 are merely illustrative. Based on the understanding of the above embodiments, those skilled in the art should be able to easily change the type of electrochemical reaction, and these changes should fall within the scope of protection of the present utility model.

[0096] In one example, the exhaust port 239 can be connected to the external environment of the refrigerator 10, and the oxygen separated by the electrolytic deoxidation device 230 can be discharged from the refrigerator 10 through the exhaust port 239. In other embodiments, the exhaust port 239 can also be connected to the refrigerating compartment 111 or the freezing compartment 112 of the refrigerator 10, so that the refrigerating compartment 111 or the freezing compartment 112 becomes an "oxygen-rich compartment", that is, the oxygen content of the refrigerating compartment 111 or the freezing compartment 112 is increased. In this way, the user can store "oxygen-loving" ingredients in the oxygen-rich space to obtain a better storage effect.

[0097] Furthermore, the electrolytic deoxygenation device 230 may also include a liquid replenishing box 236, a water pipe 237 and a water pump 238. The positions of the liquid replenishing box 236, the water pipe 237 and the water pump 238 may be arranged in a targeted manner according to actual needs. The liquid replenishing box 236 is filled with electrolyte, the water pipe 237 connects the liquid replenishing box 236 with the liquid storage chamber 235, and the water pump 238 is arranged on the water pipe 237. After the water pump 238 is started, the electrolyte in the liquid replenishing box 236 can be smoothly transported to the liquid storage chamber 235 to achieve liquid replenishment.

[0098] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
