Technical Field

[0001] The utility model belongs to the technical field of refrigerators, and specifically provides a refrigerator back plate and a refrigerator with a sterilization function. Background Art

[0002] A refrigerator is a device that keeps food fresh by freezing and / or refrigerating. Although existing refrigerators inhibit the oxidation and respiration of food through low temperatures and reduce the activity of microorganisms inside the refrigerator, existing refrigerators still breed bacteria during long-term use, affecting the health of users.

[0003] For this reason, some manufacturers have introduced sterilization boxes, which are placed in refrigerators when they leave the factory, or purchased separately by users as needed and placed in refrigerators.

[0004] The existing sterilization boxes are usually placed randomly on the shelves of the refrigerator, which is not only unsightly but also seriously squeezes the effective use space of the refrigerator, resulting in a poor user experience. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that the sterilization box in the existing refrigerator occupies the effective use space of the refrigerator.

[0006] Another purpose of the utility model is to replace the sterilization material of the sterilization module.

[0041] It should be understood by those skilled in the art that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and the embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0042] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0043] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0044] In addition, it should be noted that in the description of the present utility model, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target object (such as an evaporator, air, condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target object will release "heat" while absorbing "cold", and will absorb "heat" while releasing "cold". A certain target object stores "cold" or "heat" in order to keep the current temperature of the target object. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target object (such as an evaporator) will absorb heat while cooling.

[0045] like Figures 1 to 7 As shown, in some embodiments of the present invention, a refrigerator back panel 100 with a sterilization function includes a back panel body 110 and a sterilization module 120 .

[0046] The back panel body 110 is used to be installed on the refrigerator 200 .

[0047] The sterilization module 120 includes a module body 121 and a cover 122 . The module body 121 is fixedly connected to or integrally formed with the back plate body 110 . The module body 121 is provided with a receiving cavity 1211 for placing sterilization materials. The cover 122 is used to open and cover the receiving cavity 1211 .

[0048] It will be understood by those skilled in the art that by fixedly connecting the module body 121 of the sterilization module 120 to the back panel body 110 or forming them as one piece, the sterilization module 120 of the utility model can be suspended above the shelf and no longer needs to be placed on the shelf of the refrigerator 200. Therefore, the utility model overcomes the problem of the sterilization module 120 occupying the effective use space of the refrigerator 200.

[0049] It should be noted that, in the present invention, the effectively used space specifically refers to the space occupied by food in the refrigerator 200, especially the space on the shelves.

[0050] In addition, the utility model provides a receiving cavity 1211 for placing sterilization materials on the module body 121, and configures a cover 122 for opening and shielding the receiving cavity 1211 for the sterilization module 120, so that the user can take out the old sterilization materials from the receiving cavity 1211 by opening the cover 122, and place the new sterilization materials into the receiving cavity 1211. Therefore, the utility model also enables the user to replace the sterilization materials of the sterilization module 120 by himself, ensuring the sterilization effect of the sterilization module 120.

[0051] like Figures 6 to 10 As shown, in some embodiments of the present invention, one of the module body 121 and the cover body 122 is provided with a plug-in structure 1212, and the other of the module body 121 and the cover body 122 is provided with a plug-in matching structure 1221. The module body 121 and the cover body 122 are plugged together through the plug-in structure 1212 and the plug-in matching structure 1221.

[0052] It will be understood by those skilled in the art that by providing a plug-in structure 1212 in one of the module body 121 and the cover body 122, and providing a plug-in mating structure 1221 in the other of the module body 121 and the cover body 122, the module body 121 and the cover body 122 can be plugged together through the plug-in structure 1212 and the plug-in mating structure 1221, which makes it convenient for users to install the cover body 122 on the module body 121 or remove it from the module body 121.

[0053] Further, from Figures 6 to 10 It can be seen that in some embodiments of the present invention, the plug-in structure 1212 is a slot disposed on the module body 121 , and the plug-in mating structure 1221 is a protrusion disposed on the cover body 122 .

[0054] from Figure 7 and Fig.10 It can also be seen that the slot is an annular groove arranged around the accommodating cavity 1211, and the protrusion is an annular protrusion matching the annular groove.

[0055] In addition, in other embodiments of the present invention, those skilled in the art may also set the plug-in structure 1212 and the plug-in matching structure 1221 to any other feasible structure as needed. For example, the plug-in structure 1212 is set as a protrusion formed on the module body 121, and the plug-in matching structure 1221 is set as a slot formed on the cover body 122.

[0056] Furthermore, those skilled in the art may also set the slot and the protrusion to any other feasible shape as needed, such as setting the slot to an L-shape and setting the protrusion to an L-shape.

[0057] Alternatively, those skilled in the art may also use other methods to detachably connect the cover 122 and the module body 121 as needed, such as connecting them together by magnetic attraction or by snapping.

[0058] Exemplarily, one of the module body 121 and the cover body 122 is provided with a magnet, and the other of the module body 121 and the cover body 122 is provided with a magnetic attraction structure. The module body 121 and the cover body 122 are attracted together by the magnet and the magnetic attraction structure. The magnetic attraction structure is a magnet or a structure that can be attracted by a magnet.

[0059] like Fig.10 As shown, in some embodiments of the present invention, a buckle 1222 is provided on the cover 122 so that the cover 122 can be removed from the module body 121 by the buckle 1222 .

[0060] Those skilled in the art will appreciate that, by providing the buckle 1222 on the cover 122, the user can remove the cover 122 from the backplane body 110 or the module body 121 by prying the buckle 1222 with a fingernail, a finger or a tool. Those skilled in the art will appreciate that, compared with a cover 122 without the buckle 1222, the cover 122 with the buckle 1222 is more convenient for the user to remove the cover 122.

[0061] like Fig.10 As shown, the buckle handle 1222 can be set at the lower right corner of the cover body 122, and the buckle handle 1222 is thinner than the cover body 122, so that when the cover body 122 is covered on the module body 121, a gap can be formed between the buckle handle 1222 and the module body 121 for the user's fingers or nails to insert.

[0062] like Figures 1 to 6 As shown, the module body 121 protrudes from the front side of the back plate body 110 . The sterilization module 120 further includes a light strip 123 located at the front side of the back plate body 110 and surrounding the module body 121 .

[0063] like Figure 6 and Figure 8 As shown, in some embodiments of the present invention, a boss 1214 for winding the light strip 123 is provided on the module body 121 , and an annular outer edge 1215 for shielding the light strip 123 is provided on the front side of the boss 1214 of the module body 121 .

[0064] It is understood by those skilled in the art that by providing a light strip 123 surrounding the module body 121 on the front side of the back plate body 110, the sterilization module 120 of the utility model can visually present a sterilization visualization effect to the user with the aid of the indicator light, thereby improving the user's experience. In addition, the arrangement of the boss 1214 and the outer edge 1215 on the module body 121 also enables the module body 121 to hide the light strip 123, thereby improving the overall aesthetics of the refrigerator back plate 100.

[0065] like Figures 6 to 9 and Fig.11 As shown, in some embodiments of the present invention, a plurality of air holes 1213 are provided on the peripheral wall of the accommodating cavity 1211, and a plurality of through holes 1231 are provided on the light strip 123, so as to connect the accommodating cavity 1211 with the outside of the sterilization module 120 through the air holes 1213 and the through holes 1231.

[0066] In addition, those skilled in the art may also provide a plurality of vent holes 1213 on only one side wall of the accommodating cavity 1211 as needed.

[0067] Return to view Figures 2 to 6 In some embodiments of the present invention, a mounting hole 111 is provided on the back plate body 110. The sterilization module 120 may further include a rear shell 124 provided on the rear side of the back plate body 110, the rear shell 124 is fixedly connected to the module body 121, and at least one of the rear shell 124 and the module body 121 is engaged with the mounting hole 111 to prevent the module body 121 from shaking.

[0068] like Figure 4 and Figure 6 As shown, the mounting hole 111 on the back plate body 110 is a stepped hole, and a stepped structure 1241 is provided at one end of the rear shell 124 close to the module body 121 , and the stepped structure 1241 is embedded in the stepped hole.

[0069] Those skilled in the art can understand that the step hole and step structure 1241 that fit together can not only prevent the rear shell 124 from shaking in the up, down, left, and right directions relative to the back panel body 110, but also prevent the rear shell 124 from moving toward the front side of the back panel body 110.

[0070] Furthermore, the rear shell 124 is interference-fitted with the mounting hole 111 , so that the rear shell 124 is fixed to the backplane body 110 by means of interference-fit.

[0071] Alternatively, those skilled in the art may also, as needed, provide a slot on one of the rear shell 124 and the back panel body 110 (specifically, the surrounding wall of the mounting hole 111) and a buckle on the other, so that the rear shell 124 and the back panel body 110 are fixedly connected together in a snap-fit ​​manner.

[0072] Alternatively, those skilled in the art may also apply glue between the rear shell 124 and the back panel body 110 as needed, so that the rear shell 124 and the back panel body 110 are fixed together by bonding.

[0073] like Figure 8 As shown, a threaded hole column 1216 is provided on one side of the module body 121 facing the rear housing 124 so as to fix the module body 121 and the rear housing 124 together by bolts or screws.

[0074] Specifically, the rear shell 124 is provided with a through hole (not shown) vertically corresponding to the threaded hole column 1216, and the threaded hole column 1216 corresponds to the through hole one by one. When the module body 121 is fixed to the rear shell 124, a bolt or a screw is passed through the through hole on the rear shell 124 and is tightened to the threaded hole column 1216, so as to fix the module body 121 and the rear shell 124 together.

[0075] In some embodiments of the present invention, the rear shell 124 is used to place and accommodate structures such as wires and controllers.

[0076] In addition, those skilled in the art may also omit the rear shell 124 as needed, provided that the module body 121 can be fixed to the backplane body 110. For example, the module body 121 may be pasted to the backplane body 110 or fixed to the backplane body 110 by screws.

[0077] like Figure 3 , Figure 4 and Figure 6 As shown, the sterilization module 120 also includes a sterilization material disposed in the accommodating cavity 1211 , and the sterilization material is a replaceable filter element 125 .

[0078] The filter element 125 may be made of a porous material such as sponge, cotton, or carbon to ensure air permeability. Furthermore, the filter element 125 may also contain a substance having a bactericidal effect such as copper ions, silver ions, or iron ions.

[0079] In addition, in other embodiments of the utility model, those skilled in the art can also set the filter element 125 to any other feasible structure or material as needed. For example, the filter element 125 is configured as a metal mesh, a rectangular plate, a disc or the like with a photocatalyst (such as titanium dioxide) coated on the surface, and an ultraviolet lamp is configured for the refrigerator 200, so that the ultraviolet light emitted by the ultraviolet lamp irradiates the filter element 125, thereby activating the photocatalyst on the filter element 125, and then sterilizing by the photocatalyst.

[0080] like Figure 6 As shown, when the refrigerator back plate 100 is assembled, the rear shell 124 is embedded in the mounting hole 111 on the back plate body 110, the module body 121 is fixedly connected to the rear shell 124, and the light strip 123 is wrapped around the boss 1214 on the module body 121. A filter element 125 is placed in the accommodating cavity 1211 of the module body 121. The cover body 122 is plugged into the module body 121.

[0081] Furthermore, when the refrigerator back plate 100 is assembled, those skilled in the art can also make the module body 121 butt against the rear shell 124 as needed. For example, the threaded hole column 1216 on the module body 121 is made long enough so that when the module body 121 and the rear shell 124 are fixed together by bolts or screws, the threaded hole column 1216 butts against the rear shell 124.

[0082] Alternatively, those skilled in the art may also provide other abutment structures on the module body 121 or the rear shell 124 as required, for example, a columnar structure extending from the rear side wall of the rear shell 124 toward the module body 121 .

[0083] Those skilled in the art can understand that the abutment structure between the module body 121 and the rear shell 124 of the utility model can ensure that the air in the accommodating chamber 1211 flows to the outside of the sterilization module 120 through the air holes 1213 on the module body 121 and the through holes 1231 on the light strip 123; and the outside air flows to the accommodating chamber 1211 through the through holes 1231 on the light strip 123 and the air holes 1213 on the module body 121. Therefore, the sterilization effect of the filter element 125 on the outside air is ensured.

[0084] like Fig.12 As shown, in other embodiments of the present invention, the present invention further provides a refrigerator 200, and the refrigerator 200 includes the refrigerator back panel 100 described in any of the above embodiments.

[0085] Specifically, the refrigerator 200 includes a housing 210 , which defines at least one storage compartment 211 , and a refrigerator back plate 100 is disposed at a rear side of at least one of the at least one storage compartment 211 .

[0086] In addition, although not shown in the figure, in some embodiments of the present invention, the refrigerator 200 further includes a door body, a refrigeration system, a fan and other components installed on the box body 210 for shielding the storage compartment 211. Since other components not shown in the figure are not directly related to the technology to be solved by the present invention, the present invention will not be described in detail.

[0087] For example, a refrigeration system includes a compressor, a condenser, a pressure reducing component, and an evaporator. The refrigerant in the refrigeration system may circulate along the following path: compressor→condenser→pressure reducing component→evaporator→compressor.

[0088] Specifically, when the refrigerant flows through the compressor, it is compressed by the compressor into a high temperature and high pressure state (liquid or gas-liquid mixed state). When the refrigerant flows through the condenser, the condenser dissipates heat and the temperature is reduced to a low temperature and high pressure state (liquid or gas-liquid mixed state). When the refrigerant flows through the pressure reducing component, it is throttled and reduced to a low temperature and low pressure state (liquid or gas-liquid mixed state) by the pressure reducing component. When the refrigerant flows through the evaporator, it absorbs heat from the external environment through the evaporator and heats up to a high temperature and low pressure state (gaseous state).

[0089] It should be noted that the aforementioned states of the refrigerant in the compressor, condenser, pressure reducing component and evaporator, that is, the high temperature, low temperature, high pressure and low pressure of the refrigerant, are the states of the refrigerant after entering the corresponding components or flowing out of the corresponding components compared to the states before it flows into the corresponding components.

[0090] Furthermore, although not shown in the figures, in the present utility model, those skilled in the art may also, as needed, configure the refrigerator 200 so that the light strip 123 is illuminated when there is a filter element 125 in the sterilization module 120, and is extinguished when there is no filter element 125, so as to present the sterilization visualization to the user and remind the user whether the sterilization module 120 is working.

[0091] In order to achieve the above purpose, a sensor can be provided on the module body 121 to detect whether there is a filter element 125 in the accommodating cavity 1211. The sensor can be any feasible sensor such as a pressure sensor, a pressure switch, a micro switch, an infrared sensor, etc.

[0092] Furthermore, those skilled in the art may also configure the refrigerator 200 as needed to start timing when the filter element 125 is just placed in the accommodating cavity 1211, that is, when the sensor on the module body 121 detects the filter element 125. When the timing reaches a preset time, the light strip 123 is controlled to remain off, or to flash, or to change the flashing frequency of the light strip 123, or to change the luminous color of the light strip 123, so that the user can replace the filter element 125 according to the change of the light strip 123.

[0093] When the user replaces the filter element 125 , the cover 122 is first removed, and then the old filter element 125 is taken out from the accommodating cavity 1211 , and a new filter element 125 is installed in the accommodating cavity 1211 . Finally, the cover 122 is installed on the module body 121 .

[0094] The preset time is the service life of the filter element 125, and its specific value can be determined according to the material of the filter element 125. For example, the preset time can be 15 days, 2 months, half a year, etc.

[0095] In addition, those skilled in the art may also configure the refrigerator 200 as needed so that the light strip 123 is lit when there is a filter element 125 in the sterilization module 120 and the door of the refrigerator 200 is opened, and is off in other situations.

[0096] Specifically, when the sterilization module 120 has a filter element 125, when the refrigerator 200 detects that the door of the storage compartment 211 with the sterilization module 120 is opened, the control light strip 123 is turned on. When the door of the storage compartment 211 with the sterilization module 120 is detected to be closed, the control light strip 123 is turned off.

[0097] In a state where there is no filter element 125 in the sterilization module 120 , the control light strip 123 remains off regardless of whether the door of the storage compartment 211 having the sterilization module 120 is opened.

[0098] It should be noted that, in the present invention, when the light strip 123 is lit, it can be continuous light emission; or the light bulbs or diodes on the light strip 123 can be lit and extinguished in sequence, thereby forming a marquee effect.

[0099] So far, the technical solution of the utility model has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the utility model is not limited to these specific embodiments.
