Description

Technical Field

[0001] This invention belongs to the field of refrigerators, and specifically provides a drawer and a refrigerator for use in a refrigerator. Background Technology

[0002] As living standards improve, consumers have higher demands for refrigerators, hoping to extend the shelf life of food. Oxygen in the air is highly reactive and can cause various spoilage reactions and deterioration in food. Oxygen participates in oxidation reactions, damaging nutrients, pigments, flavor compounds, and other components of food. At the same time, oxygen is essential for the growth of aerobic microorganisms. Under aerobic conditions, the spoilage reaction caused by microbial reproduction accelerates, leading to a shorter shelf life of food.

[0003] To overcome the above problems, some refrigerators are equipped with a controlled atmosphere device (CAD), which absorbs oxygen from the drawers, thereby reducing the oxygen content in the drawer space. Specifically, the CAD device includes a cathode, an anode, and an electrolyte filled between the cathode and anode. The CAD device contacts the air in the drawer space through the cathode, causing oxygen to undergo a reduction reaction at the cathode: O₂ + 2H₂O + 4e⁻. - →4OH - An oxidation reaction occurs at the anode, producing oxygen, i.e., 4OH⁻. - →O2 + 2H2O + 4e - This allows the controlled atmosphere device to regulate the oxygen concentration within the space containing the drawer.

[0004] Because the oxygen inside the drawer is continuously reduced by the controlled atmosphere device, the air pressure inside the drawer decreases, creating negative pressure. This negative pressure makes the drawer difficult to open. Summary of the Invention

[0005] One objective of this invention is to solve the problem that drawers in existing refrigerators are difficult to open due to negative pressure inside.

[0006] A further objective of this invention is to prevent outside air from entering the drawer during use.

[0007] To achieve the above objectives, the present invention provides, in a first aspect, a drawer for a refrigerator, the drawer comprising:

[0008] ontology;

[0009] The first door body is fixedly connected to or integrally formed with the main body, and the first door body is provided with pressure equalization holes;

[0010] A cover, which is installed on the first door body, is used to cover the pressure equalization hole;

[0011] The second door body is rotatably connected to the first door body and is located on the side of the first door body away from the main body. The second door body is used to drive the cover body to open the pressure equalization hole.

[0012] Optionally, the cover is positioned on the side of the first door away from the second door, and the cover is pivotally connected to the first door via its top end, so that the cover swings under its own weight to a position that covers the pressure equalization hole.

[0013] Optionally, at least one of the cover and the first door is provided with a magnet, which is used to keep the cover in a position that covers the pressure equalization hole.

[0014] Optionally, a torsion spring is provided between the cover and the first door, the torsion spring being used to keep the cover in a position that covers the pressure equalization hole.

[0015] Optionally, the second door includes an operating part located above its pivot and a driving part located below its pivot. The operating part is used for an operator to pull out the drawer, and the driving part is able to pass through the pressure equalization hole and push open the cover.

[0016] Optionally, the second door also includes a support portion located below its pivot, the support portion being used to abut against the first door so that an operator can pull out the drawer through the operating portion.

[0017] Optionally, the drawer further includes a spring disposed between the first door and the second door, the spring being used to apply a force to the second door to move the drive portion away from the first door, so as to ensure that the cover covers the pressure equalization hole.

[0018] Optionally, the spring is a tension spring disposed above the pivot of the second door; or, the spring is a compression spring disposed below the pivot of the second door.

[0019] The present invention provides a refrigerator in a second aspect, comprising a cabinet and a drawer as described in any one of the first aspects, the drawer being installed into the cabinet in a pull-out manner.

[0020] Optionally, the refrigerator further includes a sleeve installed into the cabinet body, and the drawer is installed into the sleeve by being pulled out; the first door abuts against the front end face of the sleeve when the drawer is inserted into the sleeve.

[0021] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of the present invention, by providing a pressure equalization hole on the first door, configuring a cover to shield the pressure equalization hole, and providing a second door for driving the cover, the user can open the cover through the second door when pulling out the drawer, thereby equalizing the air pressure inside the sleeve with the ambient air pressure. This avoids the situation where the modified atmosphere device consumes oxygen inside the sleeve, resulting in low air pressure inside the sleeve, making it difficult for the user to open the drawer. Therefore, the drawer of the present invention can be opened more easily.

[0022] Furthermore, by providing a magnet on at least one of the cover and the first door, or by providing a torsion spring between the cover and the first door, the cover can tightly block the pressure equalization hole with the help of the magnet or the torsion spring, preventing the cover from being opened due to the negative pressure inside the drawer, thereby preventing outside air from entering the drawer.

[0023] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0035] Those skilled in the art should understand that the embodiments described below are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. These partial embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0036] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Furthermore, it should be noted that in the description of this invention, the terms "coldness" and "heat" are two descriptions of the same physical state. That is, the higher the "coldness" of a target object (e.g., evaporator, air, condenser, etc.), the lower its "heat," and vice versa. A target object absorbs "coldness" while releasing "heat," and releases "coldness" while absorbing "heat." A target object retains "coldness" or "heat" to maintain its current temperature. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon; that is, a target object (e.g., an evaporator) absorbs heat while refrigerating.

[0039] The drawer in this invention will be described in detail below, taking into account the specific structure of a refrigerator.

[0040] like Figure 1 As shown, in some embodiments of the present invention, the refrigerator includes a cabinet 10, an evaporator 20, a cooling fan 30, and an inner liner 40. The cabinet 10 defines a cooling compartment 11, and the evaporator 20 and the cooling fan 30 are arranged within the cooling compartment 11. The inner liner 40 is installed inside the cabinet 10 and communicates with the cooling compartment 11, so that, under the action of the cooling fan 30, cold air from the cooling compartment 11 enters the inner liner 40 to cool the food inside. Furthermore, the air in the inner liner 40 flows back into the cooling compartment 11 and is cooled again by the evaporator 20.

[0041] like Figures 2 to 4 As shown, in some embodiments of the present invention, the refrigerator further includes a drawer 50, a sleeve 60, and an air duct cover 70 arranged in the inner liner 40. The sleeve 60 is located at the bottom of the inner liner 40, and the drawer 50 is installed into the sleeve 60 in a pull-out manner. The air duct cover 70 is located above the sleeve 60 and forms an air duct 80 between it and the rear side wall of the inner liner 40.

[0042] like Figure 3 and Figure 5 As shown, in some embodiments of the present invention, the duct cover 70 is provided with a plurality of air outlets 71 so that cold air in the duct 80 is blown out from the air outlets 71. The rear sidewall of the inner liner 40 is provided with return air inlets 41 on both sides of the duct cover 70 so that air in the inner liner 40 flows back to the cooling chamber 11 through the return air inlets 41. The top of the rear sidewall of the inner liner 40 is provided with an air inlet 42 communicating with the duct 80 so that cold air in the cooling chamber 11 enters the duct 80 through the air inlet 42.

[0043] like Figures 4 to 6As shown, in some embodiments of the present invention, the refrigerator further includes a controlled atmosphere device 90, which is mounted on the sleeve 60 and located at the rear upper part of the sleeve 60. Further, an opening (not shown) communicating with the controlled atmosphere device 90 is provided at the rear upper part of the sleeve 60. Still further, the controlled atmosphere device 90 is installed within an air duct 80.

[0044] Continue reading Figures 4 to 6 In some embodiments of the present invention, the controlled atmosphere device 90 includes a cathode 91, an anode 92, and an electrolyte (not shown) filled between the cathode 91 and the anode 92. The controlled atmosphere device 90 absorbs oxygen from the sleeve 60 through the cathode 91 and releases oxygen to the outside of the sleeve 60 (specifically, into the air duct 80) through the anode 92. Specifically, oxygen undergoes a reduction reaction at the cathode 91: O2 + 2H2O + 4e- → 4OH-. An oxidation reaction occurs at the anode 92, generating oxygen: 4OH- → O2 + 2H2O + 4e-.

[0045] Those skilled in the art will understand that, although the air outlet of the modified atmosphere device 90 is not explicitly shown in the figure, in some embodiments of the present invention, the modified atmosphere device 90 has an air outlet communicating with its anode 92 so that oxygen at the anode 92 can be discharged into the air duct 80 through the air outlet.

[0046] from Figures 4 to 6 As can be seen, both cathode 91 and anode 92 are plate-shaped or sheet-shaped structures, and cathode 91 and anode 92 are generally arranged horizontally to ensure that the space between cathode 91 and anode 92 is filled with electrolyte and to prevent gaps from appearing between cathode 91 and anode 92.

[0047] Continue reading Figures 4 to 6 In some embodiments of the present invention, the sleeve 60 defines a liquid guiding cavity 61 located below the controlled atmosphere device 90, and the side wall of the liquid guiding cavity 61 is provided with a drain hole 62. The liquid guiding cavity 61 is used to collect the electrolyte leaking from the controlled atmosphere device 90, and the drain hole 62 is used to discharge the electrolyte in the liquid guiding cavity 61.

[0048] Those skilled in the art will understand that when the electrolyte in the controlled atmosphere device 90 leaks, the electrolyte will fall into the liquid guiding cavity 61 under its own gravity, and then be discharged from the liquid guiding cavity 61 through the drain hole 62, preventing the electrolyte from contaminating the food in the drawer 50.

[0049] Those skilled in the art can also, as needed, provide effective protection for the cathode 91 of the modified atmosphere device 90, as the cathode 91 is usually a diaphragm structure and is easily punctured by sharp food ingredients, by setting up the liquid guiding cavity 61, thus preventing the cathode 91 from being punctured.

[0050] Continue reading Figures 4 to 6 In some embodiments of the present invention, a drain hole 62 is formed on the rear sidewall of the sleeve 60, and the drain hole 62 is located at the lowest position of the bottom surface of the liquid guiding cavity 61.

[0051] Furthermore, the bottom surface of the liquid guiding cavity 61 is set as a V-shaped surface with the left and right sides facing each other, and the bottom surface of the liquid guiding cavity 61 is inclined downward from front to back so that the conductive liquid in the liquid guiding cavity 61 can flow to the drain hole 62.

[0052] In addition, those skilled in the art can also set the bottom surface of the liquid guiding cavity 61 to other feasible shapes as needed, for example, making the height of the bottom surface of the liquid guiding cavity 61 gradually decrease along the direction close to the drain hole 62.

[0053] like Figure 4 and Figure 5 As shown, a vent (not marked in the figure) is provided on the front side wall of the liquid guiding chamber 61 to allow oxygen in the sleeve 60 to enter the liquid guiding chamber 61 through the vent and then contact the cathode 91 of the controlled atmosphere device 90. The refrigerator also includes a fan 110 located at the air inlet 42, which drives air in the sleeve 60 into the liquid guiding chamber 61, thereby accelerating the absorption of oxygen in the sleeve 60 by the controlled atmosphere device 90. Furthermore, the refrigerator also includes a waterproof and breathable membrane 120 for covering the air inlet 42 to prevent water vapor in the sleeve 60 from entering the liquid guiding chamber 61 and contacting the cathode 91, thus affecting the reduction reaction.

[0054] In addition, those skilled in the art may, as needed, place the vent on the left or right side wall of the liquid guiding cavity 61.

[0055] Furthermore, those skilled in the art may omit at least one of the front side wall, left side wall, and right side wall of the liquid guiding cavity 61 as needed. Alternatively, those skilled in the art may omit the fan 110 and the waterproof and breathable membrane 120 as needed, thereby allowing oxygen within the sleeve 60 to automatically diffuse to the cathode 91 of the controlled atmosphere device 90.

[0056] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the refrigerator further includes a drain pipe 130 and a drain valve 140. The drain pipe 130 is sealed to the drain hole 62 through its top end, and the drain pipe 130 is sealed to the drain valve 140 through its bottom end.

[0057] like Figure 7As shown, in some embodiments of the present invention, the drain valve 140 includes a valve body 141 and a valve 142, with the valve 142 pivotally connected to the valve body 141 via its top end. Furthermore, a magnet 143 is provided on the valve body 141 so that the valve 142 automatically closes the valve body 141 under the action of the magnet 143. That is, the open valve 142 can be attracted by the magnet 143 to the position where the valve body 141 is closed, preventing outside air from entering the liquid guiding chamber 61.

[0058] In addition, those skilled in the art may, as needed, place the magnet 143 on the valve 142. Alternatively, magnets 143 may be placed on the valve body 141 and the valve 142 respectively, and the magnets 143 on the valve body 141 and the valve 142 may attract each other.

[0059] Furthermore, to ensure that valve 142 is quickly opened when there is conductive liquid in drain valve 140, a magnet 143 can be installed on valve 142, and an electromagnetic coil can be installed on valve body 141. When the electromagnetic coil is energized, it generates a repulsive force with the magnet 143 on valve 142, thereby opening valve 142. Further, drain valve 140 also includes a first terminal and a second terminal connected in series with the electromagnetic coil. The first and second terminals are spaced apart within valve body 141. When the first and second terminals are immersed in electrolyte, they become conductive, thus energizing the electromagnetic coil.

[0060] More specifically, the first terminal is connected in series with the power supply, and the second terminal is connected in series with the electromagnetic coil, which is also connected in series with the power supply. When the conductive liquid in the gas regulating device leaks and flows to the drain valve 140, the first and second terminals are immersed in the electrolyte and become conductive, thereby energizing the electromagnetic coil. The energized electromagnetic coil interacts with the magnet 143 on the valve 142, generating a repulsive force that opens the valve 142, allowing the conductive liquid in the drain valve 140 to flow out.

[0061] like Figure 5 and Figure 7 As shown, in some embodiments of the present invention, the bottom of the inner liner 40 is also provided with a through hole 43, which is aligned with the drain valve 140 so that the conductive liquid flows out through the through hole 43 to the outside of the inner liner 40 after being discharged from the drain valve 140.

[0062] Go back and continue reading Figure 4 and Figure 5In some embodiments of the present invention, the drawer 50 includes a body 51, a first door 52 fixedly connected to or integrally formed with the body 51, a cover 53 mounted on the first door 52, and a second door 54 rotatably connected to the first door 52 and located on the side of the first door 52 away from the body 51. After the drawer 50 is inserted into the sleeve 60, the first door 52 abuts against the front end of the sleeve 60 through its inner surface. Preferably, the first door 52 and the front end of the sleeve 60 are abutted together in a sealed manner. For example, a sealing ring or sealing gasket is provided on the inner surface of the first door 52 so that the first door 52 abuts against the sleeve 60 in a sealed manner through the sealing ring or sealing gasket.

[0063] like Figure 8 and Figure 9 As shown, the first door 52 is provided with a pressure equalization hole 521, which is used to connect the inner and outer sides of the drawer 50 to equalize the air pressure inside the drawer 50. The lid 53 is located on the side of the first door 52 away from the second door 54. The lid 53 is pivotally connected to the first door 52 through its top end, so that the lid 53 swings to a position that blocks the pressure equalization hole 521 by its own weight.

[0064] Optionally, at least one of the cover 53 and the first door 52 is provided with a magnet 143, so as to keep the cover 53 in the position of shielding the pressure equalization hole 521 by the magnet 143, so as to prevent the cover 53 from being opened by the negative pressure in the sleeve 60 when the gas in the sleeve 60 decreases.

[0065] Alternatively, those skilled in the art may, as needed, provide a torsion spring between the cover 53 and the first door 52 to keep the cover 53 in a position that shields the pressure equalization hole 521.

[0066] Continue reading Figure 8 and Figure 9 The second door 54 includes an operating part 541 located above its pivot and a driving part 542 located below its pivot. The operating part 541 is used by an operator to pull out the drawer 50, and the driving part 542 can pass through the pressure equalization hole 521 and push open the cover 53. Furthermore, the second door 54 also includes a support part 543 located below its pivot, which is used to abut against the first door 52 (e.g., ...). Figure 8 (as shown), so that the operator can pull out the drawer 50 through the operating section 541.

[0067] Continue reading Figure 8 and Figure 9 In some embodiments of the present invention, the drawer 50 further includes a spring 55 disposed between the first door body 52 and the second door body 54. The spring 55 is used to apply a force to the second door body 54 to move the drive part 542 away from the first door body 52, so as to ensure that the cover 53 covers the pressure equalization hole 521.

[0068] from Figure 8 and Figure 9 As can be seen, the spring 55 is a tension spring located above the pivot of the second door 54. Specifically, one end of the spring 55 is hooked to the first door 52, and the other end of the spring 55 is hooked to the second door 54.

[0069] In addition, those skilled in the art may, as needed, configure the spring 55 as a compression spring located below the pivot of the second door body 54.

[0070] like Figure 8 As shown, when the user pulls the drawer 50 outward, the user pulls the operating part 541 of the second door 54 outward, thereby moving the drive part 542 towards the cover 53. When the support part 543 abuts against the first door 52, the drive part 542 has passed through the pressure equalization hole 521 and opened the cover 53, and the air pressure on the inside and outside of the drawer 50 reaches equilibrium. As the user continues to pull the second door 54 outward, the drawer 50 moves with the second door 54 and is pulled out from the sleeve 60.

[0071] like Figure 9 As shown, when the user releases the second door 54, the second door 54 moves under the action of the spring 55. Figure 9 The position shown. At this time, the drive unit 542 and the cover 53 are no longer in contact, and the cover 53 returns to the position of shielding the pressure equalization hole 521.

[0072] Based on the foregoing description, those skilled in the art will understand that the present invention, by defining a liquid guiding cavity 61 located below the controlled atmosphere device 90 within the sleeve 60, and providing a drain hole 62 on the side wall of the liquid guiding cavity 61, allows the electrolyte leaking from the controlled atmosphere device 90 to be collected by the liquid guiding cavity 61 and discharged to the outside of the sleeve 60 through the drain hole 62. Therefore, the refrigerator of the present invention overcomes the problem of food contamination when the controlled atmosphere device 90 leaks electrolyte.

[0073] Furthermore, by pivotally connecting valve 142 to valve body 141 via its top end, and by providing magnet 143 in at least one of valve body 141 and valve 142, valve 142 can automatically close valve body 141 under the action of magnet 143, thereby enabling drain valve 140 to automatically seal when the electrolyte is completely drained, preventing external air from entering sleeve 60.

[0074] Furthermore, the present invention also provides a pressure equalization hole 521 on the first door 52, a cover 53 to shield the pressure equalization hole 521, and a second door 54 for driving the cover 53. This allows the user to open the cover 53 through the second door 54 when pulling out the drawer 50, thus equalizing the air pressure inside the sleeve 60 with the ambient air pressure. This avoids the situation where the modified atmosphere device 90 consumes oxygen inside the sleeve 60, resulting in low air pressure inside the sleeve 60 and making it difficult for the user to open the drawer 50. Therefore, the present invention also facilitates the user in opening the drawer 50.

[0075] In addition, in other embodiments of the present invention, those skilled in the art may, as needed, place components such as sleeve 60, drawer 50, and atmosphere control device 90 on the outside of inner liner 40.

[0076] The technical solutions of the present invention have been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to related technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of the present invention will fall within the scope of protection of the present invention.
