Description

Fresh-keeping storage container and refrigerator

Technical Field

The utility model relates to the technical field of refrigeration and freezing, in particular to a fresh-keeping storage container and a refrigerator.

Background technique

As a common household appliance, refrigerators can store food at low temperatures, thereby extending the storage period of food. With the improvement of people's living standards, the preservation effect of refrigerators has received more and more attention. Studies have found that magnetic fields can be used to assist in the storage of food, which greatly improves the preservation effect of food. One of the points is that under the action of the magnetic field, food can be refrigerated below zero, that is, it will not freeze below zero. This state of not freezing at sub-zero temperatures is called a supercooled non-freezing state.

However, the overcooled but not frozen state of food is relatively unstable and needs to be kept in an appropriate temperature range. If the temperature is too low, it will freeze. The most common refrigerators are air-cooled refrigerators, which blow air into the refrigerator compartment to create a low-temperature environment in the refrigerator compartment, so that the cold air blows directly on the food, which can easily cause the food to freeze due to the low temperature.

As shown in Figures 1 to 4, in one embodiment, the refrigerator includes a box body 1 and a fresh-keeping storage container 2. A storage compartment is formed in the box body 1. The fresh-keeping storage container 2 is arranged in the storage compartment. The refrigerator usually has multiple storage compartments for realizing different functions. Such as a refrigerated storage compartment 11, a frozen storage compartment, a variable temperature storage compartment, and so on. The number and function of specific storage compartments can be configured according to pre-determined requirements. The refrigerator with upper and lower compartments shown in Figure 1 is only an example, and those skilled in the art can configure the number, function and layout of specific storage compartments according to requirements.

The refrigerator of this embodiment is an air-cooled refrigerator. An air duct system is arranged in the box 1, and a fan is used to send the cold air that has been heat-exchanged by the heat exchanger (evaporator) to the storage compartment through the box air supply port, and then return to the air duct through the box air return port to achieve circulating air refrigeration. Since the box, door, and refrigeration system of this type of refrigerator are well known to those skilled in the art and easy to implement, in order not to cover up and obscure the utility model points of this application, the box, door, and refrigeration system themselves will not be described in detail below.

2 to 4, the fresh-keeping storage container includes a barrel 100, a drawer 200, a drawer cover 300 and a magnetic field assembly 400. The barrel 100 only includes an inner barrel 110. That is, the inner barrel 110 is the barrel 100. The inner barrel 110 is formed with a receiving chamber 101. The drawer 200 is arranged in the receiving chamber 101 in a pullable manner, and the drawer 200 is formed with a storage space 201. The drawer cover 300 is arranged at the top opening of the drawer 200 to cover the top opening of the drawer 200. The magnetic field assembly 400 is arranged on one side of the storage space 201, and the magnetic field assembly 400 is used to generate a magnetic field acting on the storage space 201. The barrel body 100 is provided with an air inlet 102 and an air return port 103, so as to directly or indirectly introduce a cold air flow between the drawer cover 300 and the inner top wall of the inner barrel body 110 through the air inlet 102, and make the cold air flow flow to the outside of the barrel body 100 through the air return port 103, so as to form a flowing cold air flow in the accommodating chamber 101.

As shown in FIGS. 1 to 4 , the air inlet 102 is formed on one of the left and right side walls of the inner barrel 110 , and the return air outlet 103 is formed on the other side wall. Specifically, the refrigerator is provided with an air duct connector 3 , and the air inlet 102 and the return air outlet 103 on the inner barrel 110 are both connected to the refrigeration cavity (the chamber where the evaporator is placed) of the refrigerator through the air duct connector 3 , so that cold air can enter the storage compartment 101 from the air inlet 102 via the air duct connector 3 , and the cold air flow entering the storage compartment 101 can flow between the drawer cover 300 and the inner top wall of the inner barrel 110 , that is, the cold air flow is directly introduced into the drawer cover 300 and the inner top wall of the inner barrel 110 via the air inlet 102 . The cold air flow entering the storage compartment 101 can flow out from the return air outlet 103 .

1 to 4 , the fresh-keeping storage container further includes two magnetic field assemblies 400, which are respectively arranged on opposite sides of the storage space 201. Specifically, one magnetic field assembly 400 is arranged in the rear side wall of the inner barrel 110, and the other magnetic field assembly 400 is arranged on the inner side of the front end plate 210 of the drawer 200.

It should be noted that in some other embodiments, a magnetic field component may also be provided, and the magnetic field component may be provided on the inner side of the side wall of the inner barrel body, or may be provided on the outer side of the side wall of the inner barrel body, for example, by gluing, screwing, snapping, embedding, etc., fixed to the side wall of the inner barrel body. Alternatively, it may be fixed in the interlayer of the side wall of the inner barrel body. Alternatively, it may be provided on the inner side of the side wall of the drawer, or may be provided on the outer side of the side wall of the drawer, for example, by gluing, screwing, snapping, embedding, etc., fixed to the side wall of the drawer. Alternatively, it may be fixed in the interlayer of the side wall of the drawer. Alternatively, the magnetic field component may also be provided on the drawer cover, including the top or bottom of the drawer cover. Accordingly, in the case of providing two magnetic field components, each magnetic field component may be arbitrarily provided according to the above-mentioned installation position on the basis of ensuring that the two magnetic field components are located on opposite sides of the storage space.

In the solution of this embodiment, by setting the drawer 200 in the storage chamber 101 of the inner barrel 110, and setting the drawer cover 300 at the top opening of the drawer 200, the cold air flow is directly or indirectly introduced into the space between the drawer cover 300 and the inner top wall of the inner barrel 110 through the air inlet 102 of the barrel 100, so as to cool the storage space 201 of the drawer 200. The drawer cover 300 can cover the storage space 200 of the drawer 200, so that the cold air flow cannot directly blow the food in the storage space 201, effectively avoiding the freezing of the food due to too low temperature, and ensuring the storage effect of the food under the magnetic field generated by the magnetic field assembly 400. In addition, because the cold energy has a tendency to sink, the cold air flow flows between the drawer cover 300 and the inner top wall of the inner barrel 110, which helps the cold energy to sink in the storage space 201 after heat conduction, and cools the entire storage space 201, thereby improving the temperature uniformity of the storage space 201. In addition, because the inner barrel body 110 forms a relatively small storage chamber 101, the cold air flow directly enters the storage chamber 101 for cooling, which not only ensures the cooling efficiency, but also improves the temperature uniformity in the small space, thereby also facilitating all-round uniform cooling of the drawer 200.

It should be noted that, in some other embodiments, the air inlet may also be arranged on the rear side wall or the top side wall of the inner barrel body.

As shown in FIGS. 1 to 4 , further, the air inlet 102 is located above the drawer cover 300, and the air return port 103 is located below the bottom wall of the drawer 200. Specifically, the air inlet 102 and the drawer cover 300 are projected on the same longitudinal plane, and the projection of the air inlet 102 is located above the projection of the drawer cover 300. The air return port 103 and the drawer 200 are projected on the same longitudinal plane, and the projection of the air return port 103 is located below the projection of the drawer 200.

By arranging the air inlet 102 and the air return port 103 on the left and right walls of the inner barrel 110 respectively, and making the air inlet 102 located above the drawer cover 300, and the air return port 103 located below the drawer 200, the cold air flow entering the storage chamber 101 from the air inlet 102 can partially flow through the top of the drawer cover 300, and then flow downward to the air return port 103 after passing over the drawer cover 300, and partially flow downward on the side of the drawer 200 close to the air inlet 102, and then flow from the bottom of the drawer 200 to the air return port 103, thereby forming a cold air flow around the storage space 201, so that the temperature of the storage space 201 is more uniform.

As shown in Figures 5 to 6, in another embodiment, the refrigerator includes a box body 1 and a fresh-keeping storage container 2. A storage compartment is formed in the box body 1. The fresh-keeping storage container 2 is arranged in the storage compartment. The refrigerator usually has multiple storage compartments for realizing different functions. Such as a refrigerated storage compartment 11, a frozen storage compartment, a variable temperature storage compartment, and so on. The number and function of specific storage compartments can be configured according to pre-determined requirements. The cross-door refrigerators shown in Figures 5 and 6 are only examples, and those skilled in the art can configure the number, function and layout of specific storage compartments according to requirements.

The refrigerator of this embodiment is an air-cooled refrigerator. An air duct system is arranged in the box 1, and a fan is used to send the cold air that has been heat-exchanged by the heat exchanger (evaporator) to the storage compartment through the box air supply port, and then return to the air duct through the box air return port to achieve circulating air refrigeration. Since the box, door, and refrigeration system of this type of refrigerator are well known to those skilled in the art and easy to implement, in order not to cover up and obscure the utility model points of this application, the box, door, and refrigeration system themselves will not be described in detail below.

FIG6 shows an example of a fresh-keeping storage container 2 being arranged in the refrigerated storage compartment 11. In addition to the fresh-keeping storage container 2, other storage drawers may be arranged in the refrigerated storage compartment 11. For example, FIG6 shows an example of a refrigerated storage compartment 11 being provided with three other drawer-type storage containers in addition to the fresh-keeping storage container 2, wherein one of the drawer-type storage containers is arranged horizontally in parallel with the fresh-keeping storage container 2.

Multiple storage rooms can be spatially divided by racks, shelves, drawers, etc. to achieve corresponding storage functions, such as chilled, frozen, dry storage, etc. One or more fresh-keeping storage containers can be arranged in the refrigerator of this embodiment. In some optional embodiments, the fresh-keeping storage container can be arranged in one or more of the above-mentioned multiple storage rooms, and the long-term high-quality cold preservation of food materials such as meat and fish can be achieved through magnetic field and temperature control. For example, the fresh-keeping storage container can be arranged in any one of the refrigerated storage room, the frozen storage room, and the variable temperature storage room. For another example, the fresh-keeping storage container can also be arranged in multiple refrigerated storage rooms, frozen storage rooms, and variable temperature storage rooms at the same time, that is, fresh-keeping storage containers are respectively arranged in multiple different storage rooms at the same time. For another example, multiple fresh-keeping storage containers can also be arranged in a storage room at the same time as needed.

As shown in FIGS. 7 to 11 , in the fresh-keeping storage container of this embodiment, unlike the above-mentioned embodiment, the barrel body 100 is formed with an air supply duct 10 located outside the top side wall of the inner barrel body 110, the air supply duct 10 extends along the front-to-back direction of the barrel body 100, and the air inlet 102 is arranged at the rear end of the air supply duct 10, so as to guide the cold air flow from the air inlet 102 from the back to the front through the air supply duct 10, and guide it to between the drawer cover 300 and the inner top wall of the inner barrel body 110. That is to say, the cold air flow is indirectly guided to between the drawer cover 300 and the inner top wall of the inner barrel body 110 through the air supply duct 10 by the air inlet 102. The barrel body 100 also includes an outer shell 120, which is sleeved on the outer side of the inner barrel body 110, and there is a mezzanine space between the top side wall of the outer shell 120 and the top side wall of the inner barrel body 110, and the air supply duct 10 is formed in the mezzanine space. That is, there is a gap between the top wall of the outer shell 120 and the top wall of the inner barrel 110, that is, a mezzanine space, and the air supply duct 10 is formed in the mezzanine space.

Specifically, the inner barrel 110 is box-shaped as a whole and has a forward opening (i.e., the opening of the storage chamber 101). That is to say, the inner barrel 110 has five side walls, i.e., the top side wall of the barrel, the bottom side wall of the barrel, the rear side wall of the barrel, the left side wall of the barrel, and the right side wall of the barrel, and the five side walls together surround the storage chamber 101 with an opening. The drawer 200 is arranged inside the inner barrel 110 in a retractable manner through the opening of the storage chamber 101. The drawer 200 includes a bottom plate, a rear plate, a left plate, a right plate, and a front plate 210. When the drawer 200 is in a closed position, the front plate 210 of the drawer 200 can seal the opening of the inner barrel 110, so that a closed storage environment is formed inside the inner barrel 110, that is, the internal space of the drawer 200 is enclosed in the storage chamber 101, so that the drawer 200 and the inner barrel 110 jointly define a fresh-keeping space. When the drawer 200 is pulled out of the inner barrel 110, the inner space of the drawer 200 is exposed to the outside, and the stored items can be taken in and out. The outer shell 120 is sleeved on the outer side of the inner barrel 110, and the front end plate 210 of the drawer 200 seals the opening of the inner barrel 110 and also contacts the front end of the outer shell 120.

It should be noted that the side wall of the outer shell can be formed separately or formed by the inner wall of the refrigerator compartment.

As shown in FIGS. 7 to 11 , an air supply hole 104 is provided at the front end of the air supply duct 10 to guide the cold air flow in the air supply duct 10 to between the drawer cover 300 and the inner top wall of the inner barrel body 110 via the air supply hole 104 .

As shown in Figures 7 to 11, further, the front end plate 210 of the drawer 200 is formed with an air receiving duct 20, and the top of the air receiving duct 20 has an air receiving hole 202 to guide the cold air flow to the air receiving duct 20 via the air supply duct 10, and enter the air receiving duct 20 through the air supply hole 104 and the air receiving hole 202 in turn.

Specifically, the front end panel 210 of the drawer 200 includes a panel 211 and an end panel hood 212. The end panel hood 212 is disposed on the inner side of the panel 211, and the end panel hood 212 defines an air receiving duct 20, and an air receiving hole 202 is formed at the top of the end panel hood 212. The end panel hood 212 protrudes from the panel 211 toward the inside of the drawer 200, and the left side wall, the right side wall and the bottom side wall of the end panel hood 212 are all located on the inner side of the side wall of the drawer 200. The air receiving hole 202 is formed on the top side wall of the end panel hood 212.

It should be noted that the air receiving duct can be formed by the end plate hood and the panel together, or it can be formed by the end plate hood alone (that is, the end plate hood has a side wall that fits the inner side of the panel). In addition, the end plate hood can be a component that is formed separately and subsequently assembled on the drawer, or it can be a component that is integrally formed with the drawer. Moreover, the left side wall, right side wall and bottom side wall of the end plate hood can be directly formed by the left side wall, right side wall and bottom side wall of the drawer.

As shown in FIG. 9 to FIG. 12 , the fresh-keeping storage container further includes an end plate fitting 130, which is disposed at the front end of the barrel body 100, surrounds the opening of the accommodating chamber 101, and is assembled with the outer shell 120 and the inner barrel body 110, thereby closing the air supply duct 10. At the same time, the air supply hole 104 is formed on the end plate fitting 130, so that the air flow in the air supply duct 10 can flow out from the air supply hole 104.

It should be noted that in some other embodiments, the fresh-keeping storage container may not be provided with an end plate fitting. In this case, the air supply hole may be formed on a section bent from the front end of the outer shell to the barrel liner, or formed on a section bent from the front end of the inner barrel to the barrel outer shell.

It should be noted that, in some other embodiments, when the fresh-keeping storage container only includes an inner barrel, the air supply hole can be formed by an additional component that forms an air supply duct.

9 and 10 , the plane where the outlet of the air supply hole 104 is located is inclined toward the top of the fresh-keeping storage container in a direction away from the rear end of the fresh-keeping storage container; the plane where the inlet of the air receiving hole 202 is located is inclined toward the bottom of the drawer 200 in a direction away from the panel 211.

Specifically, the portion of the end plate fitting 130 used to form the air supply hole 104 is inclined toward the top of the fresh-keeping storage container in a direction away from the rear end of the fresh-keeping storage container, that is, it is inclined toward the top of the fresh-keeping storage container in the direction of the opening of the inner barrel 110. The plane where the outlet of the air supply hole 104 is located is the plane where the bottom side of the portion is located, that is, the plane where the side away from the air supply duct 10 is located.

The top side wall of the end plate air cover 212 is inclined toward the bottom of the drawer 200 in the direction away from the panel 211, that is, it is inclined toward the bottom of the drawer 200 in the direction from the front end to the rear end of the drawer 200. The plane where the entrance of the air receiving hole 202 is located is the plane where the top surface of the end plate air cover 212 is located, that is, the plane where the side surface of the top side wall of the end plate air cover 212 is away from the air receiving air duct 20 is located.

9 and 10 , from the overall perspective of the fresh-keeping storage container, the plane where the outlet of the air supply hole 104 is located and the plane where the inlet of the air receiving hole 202 is located are inclined in the same direction, that is, they are both inclined toward the bottom of the fresh-keeping storage container from the front to the back of the fresh-keeping storage container.

By making the plane where the outlet of the air supply hole 104 is located tilted toward the top of the fresh-keeping storage container in a direction away from the rear end of the fresh-keeping storage container, and making the plane where the inlet of the air receiving hole 202 is located tilted toward the bottom of the drawer 200 in a direction away from the panel 211. In the process of the cold air entering the air receiving duct 20 from the air supply duct 10, the flow path of the cold air is generally in a parabolic shape, so that the flow of the cold air between the air supply hole 104 and the air receiving hole 202 is smoother, which is conducive to reducing air leakage. In addition, the top of the end plate wind cover 212 is inclined, which is also conducive to reducing the probability of foreign matter falling into the air receiving duct 20. At the same time, the above structure also makes it easier for the cold air flow flowing out of the air supply hole 104 to flow between the drawer cover plate 300 and the inner top wall of the inner barrel body 110.

As shown in FIGS. 9 to 13 , an air outlet 203 is provided at the bottom of the end plate air cover 212 to guide the cold air flow in the air receiving duct 20 indirectly or directly to between the bottom of the drawer 200 and the inner barrel body 110 via the air outlet 203 .

The bottom side wall of the end plate hood 212 is provided with four air outlet holes 203. The bottom side wall of the drawer 200 is also provided with corresponding through holes, so that the air flow in the air receiving duct 20 flows out from the air outlet holes 203, passes through the through holes on the bottom side wall of the drawer 200 and flows to the bottom of the drawer 200 and the inner barrel 110.

It should be noted that, in some other embodiments, the end plate hood may also be provided with an air outlet, such as a long strip air outlet extending in the left-right direction, or may be provided with two, three, five or other air outlets.

Referring to FIGS. 7 to 14 , specifically, the air inlet 102 and the air return port 103 are both arranged at the rear end of the top side wall of the outer shell 120, and the air return port 103 is arranged in parallel with the air inlet 102. The rear side wall of the inner barrel 110 forms an air outlet 105, and a longitudinally extending air duct (not shown in the figure) is formed between the rear side wall of the inner barrel 110 and the rear side wall of the outer shell 120, and the top of the air duct is connected to the air return port 103. The cold air flow flows along the bottom of the drawer 200 to the rear end of the drawer 200, then flows upward to the air outlet 105, flows from the air outlet 105 into the air outlet duct, then flows along the air outlet duct to the air return port 103, and finally flows out from the air return port 103.

In summary, the air path inside the fresh-keeping storage container is configured as follows: the airflow enters the rear end of the air supply duct 10 from the air inlet 102, and then the airflow flows through the air supply duct 10 from the back to the front. At the front end of the air supply duct 10, part of the cold air flows into the accommodating compartment 101 from the opening of the accommodating compartment 101, and flows between the drawer cover 300 and the inner top wall of the inner barrel body 110, and part of the cold air flows into the top of the air receiving duct 20 defined in the front end plate 210 of the drawer 200 through the air supply hole 104 and the air receiving hole 202, and then the airflow flows through the air receiving duct 20 from top to bottom. The airflow between the drawer cover 300 and the inner top wall of the inner barrel body 110 flows from front to back, and flows into the air outlet hole 105 at the rear end of the drawer 200. The cold air flow entering the air receiving duct 20 enters between the bottom plate of the drawer 200 and the bottom wall of the inner barrel 110 at the bottom end of the air receiving duct 20, and then flows from front to back. At the connection position between the rear end of the bottom plate of the drawer 200 and the rear plate of the drawer 200, the air flow enters the gap between the rear plate of the drawer 200 and the rear wall of the inner barrel 110, and then enters the air outlet 105. Finally, the cold air flow flows into the air outlet duct from the air outlet 105, and the air flow finally reaches the return air port 103 along the air outlet duct.

By providing the drawer cover 300 and the above-mentioned air duct structure, the cold air flow can flow through the top, front, bottom and rear sides of the storage space 201 and surround the storage space 201 well to evenly cool the storage space 201 .

It should be noted that in some other embodiments, the air duct may not be set on the front end panel of the drawer. In this case, the air supply hole can be directly facing between the drawer cover and the inner top wall of the inner barrel body, so that the cold air flows between the drawer cover and the inner top wall of the inner barrel body.

Alternatively, in some other embodiments, the air supply hole can be directed toward the front of the barrel body, and the front end plate of the drawer can block the air supply hole in front, so that the cold air flow out of the air supply hole is blocked by the front end plate of the drawer, and then the flow direction is changed, so that the cold air flow flows between the inner top wall of the barrel body inside the drawer cover.

As shown in Fig. 9, the fresh-keeping storage container further includes two magnetic field assemblies 400, which are respectively arranged on opposite sides of the storage space 201. Specifically, one magnetic field assembly 400 is located outside the top side wall of the inner barrel 110, and the other is located outside the bottom side wall of the inner barrel 110.

Specifically, a thermal insulation board 500 is further provided on the outer side of the top side wall of the inner barrel body 110, and the thermal insulation board 500 and the top side wall of the inner barrel body 110 constitute the duct wall of the air supply duct 10, and the magnetic field assembly 400 located on the top side of the inner barrel body 110 is arranged on the side of the thermal insulation board 500 away from the air supply duct 10. The thermal insulation board 500 can be a board made of a thermal insulation material, such as a thermal insulation foam board.

It is understandable that the duct wall of the air supply duct may be formed by the outer shell and the inner barrel, or other components such as a heat preservation board may be arranged in the interlayer space to form the duct wall of the air supply duct. Alternatively, the duct wall may be formed by a magnetic field assembly.

It should be noted that in some other embodiments, a magnetic field component may also be provided, and the magnetic field component may be provided on the inner side of the side wall of the inner barrel body, or may be provided on the outer side of the side wall of the inner barrel body, for example, by gluing, screwing, snapping, embedding, etc., fixed to the side wall of the inner barrel body. Alternatively, it may be fixed in the interlayer of the side wall of the inner barrel body. Alternatively, it may be provided on the inner side of the side wall of the drawer, or may be provided on the outer side of the side wall of the drawer, for example, by gluing, screwing, snapping, embedding, etc., fixed to the side wall of the drawer. Alternatively, it may be fixed in the interlayer of the side wall of the drawer. Alternatively, the magnetic field component may also be provided on the drawer cover, including the top or bottom of the drawer cover. Accordingly, in the case of providing two magnetic field components, each magnetic field component may be arbitrarily provided according to the above-mentioned installation position on the basis of ensuring that the two magnetic field components are located on opposite sides of the storage space.

Although not shown in the figure, the magnetic field assembly includes a magnetic source and a uniform magnetic plate, and the uniform magnetic plate is arranged on the side of the magnetic source away from the storage space. The magnetic source is a permanent magnetic sheet made of a composite material of ferrite magnetic powder and synthetic rubber. The uniform magnetic plate is made of a magnetic conductive material, such as silicon steel. The uniform magnetic plate and the magnetic source are arranged in a close relationship to make the magnetic field more evenly distributed inside the drawer.

It should be noted that in some other embodiments, the magnetic source may also be an electromagnetic coil. Alternatively, the magnetic field device may also be a separate permanent magnet sheet, or a separate electromagnetic coil, or the magnetic field device may also be a structure consisting of a permanent magnet sheet, an electromagnetic coil, and a uniform magnetic plate.

As shown in Figure 15, in one embodiment, the fresh-keeping storage container includes a cold storage structure 600, which is arranged on the top side of the drawer cover 300. The cold storage structure 600 can store cold energy, thereby releasing cold energy into the storage space 201 when the temperature in the storage space 201 is high, which is beneficial to maintaining the temperature in the storage space 201.

It should be noted that, in some other embodiments, the cold storage structure may also be disposed on the bottom side of the drawer cover or in the interlayer of the drawer cover. Alternatively, it may also be disposed on the side wall of the drawer, including the outer side, inner side or interlayer of the drawer side wall. Alternatively, the cold storage structure may also be disposed on the top side wall of the inner barrel, including the outer side, inner side or interlayer of the top side wall of the inner barrel.

As shown in Figure 16, in another embodiment, a plurality of ventilation holes 111 are formed on the top side wall of the inner barrel body 110 so that the cold air flowing in the air supply duct 10 partially flows through the ventilation holes 111 to between the drawer cover 300 and the inner top wall of the inner barrel body 110.

It should be noted that, in some other embodiments, the number of the ventilation hole can also be one, which is a long strip-shaped air hole extending in the front-to-back direction. In addition, the shape of the ventilation hole can be any shape.

It should be noted that the through hole provided on the top side wall of the inner barrel body and the surrounding air passage of the previous embodiment can exist at the same time.

It should be noted that, in some other embodiments, when the fresh-keeping storage container is relatively small, it can also be arranged on the refrigerator door, preferably, on the inner side of the door.

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.
