Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a vacuum preservation device and a refrigerator, and aims to solve the technical problem that an existing preservation device is single in function.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present disclosure, and the embodiment of the present disclosure provides a vacuum refreshing apparatus 10, which may be applied in the refrigerator, may also be applied in other refreshing apparatuses, and may also be used alone, which is not limited in the embodiment of the present disclosure. Taking the vacuum preservation device 10 as an example of being suitable for a refrigerator, the refrigerator may be a double-door refrigerator, and certainly, the refrigerator may also be a single-door refrigerator or a triple-door refrigerator, which is not limited in the embodiment of the present application.

As shown in fig. 1, the refrigerator may include a cabinet 20. The housing 20 may have one fresh food compartment 21 or a plurality of fresh food compartments 21. The vacuum refreshing apparatus 10 is installed in the refreshing compartment 21. Meanwhile, a second opening 22 is formed on a sidewall forming the fresh food compartment 21, so that a user can store food into the vacuum refreshing apparatus 10 and/or the interior of the fresh food compartment 21 through the second opening 22.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a vacuum refreshing apparatus and a portion of an air duct of the refrigerator shown in fig. 1. Illustratively, the vacuum refreshing apparatus 10 may include a container body 11, a vacuum assembly 12, a drawer 13, and a magnetic generating assembly 14. The container body 11 has a receiving cavity 111 therein. The drawer 13 is drawably disposed in the accommodating chamber 111, and is capable of closing and opening the accommodating chamber 111. When the accommodating cavity 111 is closed by the drawer 13, the vacuum assembly 12 may form a low vacuum environment in the accommodating cavity 111, and the magnetic generating assembly 14 may form a magnetic field into the accommodating cavity 111.

It is understood that the deterioration of food products is mainly caused by the vital activity of microorganisms. The basic life process of microorganisms is nutrition and respiration. Respiratory oxygen is a biological oxidation process with the consequent release of energy required for the vital activities of microorganisms. The respiration process of the microorganisms is also the oxidation process of food. Sugars, organic acids, alcohols and fats of the food can all become oxygenated materials in the microbial respiration process.

In the prior art, the vacuum refreshing apparatus 10 uses the vacuum assembly 12 to draw a portion of air in the accommodating cavity 111, so that a low vacuum state is formed in the accommodating cavity 111. Under the condition of low vacuum, the growth and reproduction of aerobic microorganisms can be inhibited. Therefore, the vacuum refreshing apparatus 10 can delay the food placed in the accommodating cavity 111 from being rotted, so as to realize vacuum refreshing of the food in the accommodating cavity 111. However, in the prior art, the vacuum refreshing apparatus 10 has the problem that the technical means for inhibiting the life growth is single, and the problem that the negative pressure in the accommodating chamber 111 cannot be too low in order to prevent the food in the accommodating chamber 111 from being damaged by the pressure in the low vacuum environment. The negative pressure in the accommodating cavity 111 cannot be too low, so that the vacuum refreshing effect is limited.

In order to further improve the fresh-keeping effect of the vacuum fresh-keeping device 10 under the condition that the negative pressure in the accommodating cavity 111 is constant, in the embodiment of the present application, the magnetic generating assembly 14 is arranged outside the container body 11, and the magnetic generating assembly 14 generates a magnetic field into the accommodating cavity 111. It is understood that the magnetic field may inhibit microbial activity, reduce enzyme activity, and reduce water loss from the food. The magnetic field changes the calcium ion distribution on both sides of the microbial cell membrane to cause the potential change of the cell membrane, thereby changing the permeability of the cell membrane and reducing the survival rate of the microbes. The structure of the water molecule groups can be damaged in a magnetic field, and the larger associated water molecule groups can become smaller associated water molecule groups or even single water molecules, and the water molecules are more easily attached to the surface and in the pores of the food and even absorbed, so that the water loss of the food is reduced. The magnetic field changes the catalytic activity of the enzyme by influencing the conformation of the enzyme, some enzymes contain a small amount of transition metal atoms such as iron, cobalt and manganese as active centers, and the external magnetic field can influence the active centers, thereby reducing the activity of the enzymes. Furthermore, in the embodiment of the present application, the preservation effect of the vacuum preservation device 10 can be further improved by a magnetic field preservation method under the condition that the food is not crushed by the negative pressure.

Referring to fig. 3, fig. 3 is a schematic diagram of a partial explosion structure of the vacuum refreshing apparatus of the refrigerator shown in fig. 1. In the present embodiment, the container body 11 may include a main body portion 112. The main body 112 has a receiving cavity 111 therein. A side wall forming the accommodating cavity 111 is provided with a first opening 113 at a side close to the second opening 22. The first opening 113 can communicate the accommodating chamber 111 with the outside. Therefore, the food can be accessed into the accommodating cavity 111 through the first opening 113.

As shown in fig. 3, a connecting platform 114 may be further disposed at an end of the main body 112 away from the first opening 113, so that the main body 112 can be connected and fixed to the inner wall forming the fresh-keeping compartment 21 through the connecting platform 114. For example, the connection platform 114 may be provided with a threaded hole to enable the connection platform 114 to be threadedly secured with the inner wall forming the fresh food compartment 21. Further, the mounting of the container body 11 is made more stable.

As shown in fig. 3, the main body 112 may be provided with an extension portion 115, and the extension portion 115 is disposed around the first opening 113. The extension 115 is also connected to the sidewall forming the second opening 22 all around, so as to seal the connection between the container body 11 and the second opening 22, and finally form a closed air cavity between the container body 11 and the sidewall forming the fresh-keeping compartment 21.

As shown in fig. 3, the drawer 13 may include a door panel 131 and a receiving tray 132.

In the embodiment of the present application, the receiving tray 132 may be slidably installed in the accommodating cavity 111. Illustratively, the accommodating tray 132 is provided with a slide rail, and the slide rail is slidably connected with a slide block formed on the inner wall of the accommodating cavity 111. Of course, the storage tray 132 may be provided with a slider, and the slider may be slidably connected to a slide rail formed on the inner wall of the storage groove. In the embodiment of the present application, the specific connection manner between the storage tray 132 and the accommodating cavity 111 is not limited, and only the storage tray 132 and the accommodating cavity can slide relatively.

As shown in fig. 3, the receiving tray 132 can pass through the first opening 113 of the container body 11. Therefore, the accommodating tray 132 can be inserted into the accommodating cavity through the first opening 113; alternatively, the receiving tray 132 can be separated from the receiving groove through the first opening 113.

As shown in fig. 3, the door panel 131 is fixedly connected to the receiving tray 132, and the door panel 131 is located outside the accommodating cavity 111. Therefore, the receiving tray 132 can be pulled by the door panel 131, so that the receiving tray 132 enters or exits the accommodating cavity 111. The door panel 131 and the receiving tray 132 are matched to enclose a storage space 133 with an upward opening. Therefore, when the receiving tray 132 moves to be at least partially outside the accommodating cavity 111, the food can be stored and taken in the storage space 133.

In order to form the vacuum environment in the accommodating cavity 111, in the embodiment of the present application, the door 131 can move to open the first opening 113 and move to close the first opening 113.

For example, a sealing ring may be disposed on the door panel 131, or a sealing ring may be disposed on a sidewall forming the first opening 113. When the door panel 131 moves toward the side wall forming the first opening 113, the door panel 131 and the side wall forming the first opening 113 can press the sealing ring, so that the sealing ring is deformed to seal the connection between the door panel 131 and the side wall forming the first opening 113.

In the embodiment of the present application, as shown in fig. 3, the vacuum refreshing apparatus 10 may further include a magnetic locking assembly 15, and the door 131 may be locked to the container body 11 by the magnetic locking assembly 15.

Referring to fig. 4, fig. 4 is a schematic structural view of a magnetic locking assembly of the vacuum refreshing apparatus of the refrigerator shown in fig. 1. The magnetic locking assembly 15 includes a first magnetic strip 151 and a second magnetic strip 152. The first magnetic stripe 151 is disposed on a sidewall forming the first opening 113, and surrounds the first opening 113. The second magnetic stripe 152 is disposed on the door panel 131 of the drawer 13, and the second magnetic stripe 152 can be magnetically connected with the first magnetic stripe 151 to seal the connection between the drawer 13 and the side wall forming the first opening 113.

In the present embodiment, the first magnetic stripe 151 and/or the second magnetic stripe 152 are hermetically sealed soft magnetic stripes. Therefore, the locking of the drawer 13 and the container body 11 can be realized through the magnetic locking assembly 15, and the sealing of the drawer 13 and the container body 11 can also be realized without additionally arranging a sealing ring. Therefore, the vacuum refreshing device 10 provided by the embodiment of the application has the advantages of simple structure and good use effect.

Of course, in other embodiments, the magnetic locking assembly 15 may further include a permanent magnet disposed on the container body 11 and a ferromagnetic material disposed on the drawer 13 and magnetically connected to the permanent magnet. Still alternatively, the magnetic locking assembly 15 includes an electromagnet provided on the container body 11 and a ferromagnetic material provided on the drawer 13 and magnetically connected to the electromagnet. The embodiment of the present application does not limit the specific structure of the magnetic locking assembly 15, and the magnetic scheme that only needs to lock the drawer 13 and the container body 11 is within the scope of the embodiment of the present application.

In the present embodiment, as shown in fig. 3, the vacuum assembly 12 may include a vacuum pump 121 and an air suction valve 122. Illustratively, the end of the container body 11 away from the first opening 113 is provided with a suction hole. The air exhaust hole is communicated with the accommodating cavity 111. The suction valve 122 may be a one-way valve. The check valve is disposed at a sidewall where the suction hole is formed, so that air can move only from the inside of the receiving chamber 111 to the outside of the receiving chamber 111 through the suction valve 122. The vacuum pump 121 is connected to the air suction valve 122, so that the vacuum pump 121 can suck air in the accommodating chamber 111 through the air suction valve 122.

Of course, in other embodiments, the vacuum assembly 12 may be a valve body, through which the suction hole may be selectively opened or closed. When the air suction hole is opened, the inside of the accommodating cavity 111 can be sucked by the external vacuum pump 121.

In this application embodiment, after drawer 13 seals holding chamber 111, vacuum pump 121 can be through the inside air of the subassembly air extraction holding chamber 111 that bleeds for form the low vacuum environment of 0.6 ~ 0.8 atmospheric pressure in the holding chamber 111, and then realize the fresh-keeping effect in vacuum to the food of storage in the holding chamber 111.

The magnetic generating assembly 14 may comprise a helmholtz coil. The helmholtz coil may be one or more. For example, one helmholtz coil may be disposed on the lower surface of the container body 11, one helmholtz coil may be wound around the outer surface of the container body 11, or two helmholtz coils may be disposed on the upper surface and the lower surface of the container body 11, which is not limited in this embodiment of the present application, and the technical solution that only the magnetic generating assembly 14 is disposed outside the accommodating cavity 111 and can form a magnetic field into the accommodating cavity 111 is within the protection scope of the present application.

Of course, the magnetic generating assembly 14 may also be other electromagnetic devices. It will be appreciated that a helmholtz coil or other electromagnetic device may be energized to generate a magnetic field. However, the helmholtz coil path generates heat. If the helmholtz coil is arranged in the accommodating cavity 111, heat generated by the helmholtz coil can be directly dissipated into the accommodating cavity 111, and food stored in the accommodating cavity 111 is easy to go bad and rot with higher speed after being heated. Therefore, in the embodiment of the present application, the magnetic generating assembly 14 is disposed outside the accommodating cavity 111, so that heat generated by the magnetic generating assembly 14 can be effectively prevented from being directly applied to food in the accommodating cavity 111, and the preservation effect of the vacuum preservation device 10 is further improved.

Of course, the magnetic generating assembly 14 may also be any other magnetic member capable of generating a magnetic field into the accommodating cavity 111, such as a permanent magnet, and the specific structure of the magnetic generating assembly 14 is not further limited in this embodiment of the application. The magnetic generation assembly 14 is arranged outside the accommodating cavity 111, so that the space of the accommodating cavity 111 can be effectively increased on the one hand, more food can be stored in the accommodating cavity 111, and on the other hand, the accommodating cavity 111 does not need to be opened through the drawer 13 when the magnetic generation assembly 14 needs to be disassembled and assembled, so that the vacuum preservation effect of food in the accommodating cavity 111 of the vacuum preservation device 10 cannot be influenced.

In the present embodiment, as shown in fig. 3, the magnetism generating assembly 14 may further include a bracket 141. The helmholtz coil is wound around the support 141. The bracket 141 is detachably connected to the container body 11. It can be understood that, the bracket 141 is detachably fixed, so that the vacuum refreshing apparatus 10 provided by the embodiment of the present application is more convenient to disassemble and assemble in the process of later maintenance, maintenance and adjustment.

Illustratively, as shown in fig. 3, the outer surface of the container body 11 is provided with a mounting portion 116. The mounting portion 116 has a mounting groove at a side facing away from the receiving cavity 111. The bracket 141 is detachably coupled to a sidewall forming the mounting groove. For example, the bracket 141 may be snap-fit secured to the side walls forming the mounting slot. Still alternatively, the bracket 141 may be screw-fixed to a sidewall forming the mounting groove. After the bracket 141 is fixedly connected to the side wall forming the mounting groove, a cover plate 117 may be mounted on the mounting portion 116 to close the mounting groove, thereby providing a better protection effect for the magnetic generating assembly 14.

In the embodiment of the application, the number of turns of the coil of the Helmholtz coil wound on the support 141 can be between 100-2000 turns, and the number of turns of the coil of the Helmholtz coil can be reasonably set according to the space size of the fresh-keeping compartment 21. Further, the diameter of the stent 141 should be greater than 50 mm. The magnetic field intensity of the magnetic field formed by the Helmholtz coil into the accommodating cavity 111 is between 1mt and 2 mt. Furthermore, by adjusting the intensity of the magnetic field, the vacuum refreshing apparatus 10 can achieve the refreshing effects of inactivating enzymes and sterilizing and preventing mold in different states for different foods.

Of course, it is also understood that, taking the preservation effect on beef as an example, the meat color becomes dark under low oxygen although the respiration of microorganisms is inhibited under vacuum. At the moment, the magnetic field can inhibit enzyme activity, protect the original bright red color of meat and play a role in color protection. Therefore, different food materials can be mainly subjected to vacuum preservation, magnetic field preservation or vacuum preservation, and magnetic field preservation is mainly performed. In addition, the food materials have different action efficiencies under different states. If the food material is mainly vacuumed in the initial stage, but mainly magnetized in the later stage. Not only enhances the fresh-keeping effect, but also prolongs the freshness time.

It can be understood that since the magnetic generating assembly 14 is disposed on the outer surface of the container body 11, and the container body 11 is disposed in the fresh food compartment 21, the magnetic generating assembly 14 is located in the wind cavity formed by the container body 11 and the sidewall forming the fresh food compartment 21.

As shown in fig. 1, the refrigerator may further include a cooling device 30, and the cooling device 30 is used to cool the air chamber. Furthermore, the temperature in the wind cavity can be transferred to the accommodating cavity 111 inside the container body 11 by heat conduction. Therefore, the refrigerating device 30 can refrigerate the container body 11, so that the storage cavity of the vacuum refreshing device 10 has the functions of vacuum refreshing and magnetic field refreshing, and low-temperature refreshing. On the other hand, the Helmholtz coil is arranged in the wind cavity, so that a direct and good heat dissipation effect can be achieved for the Helmholtz coil.

As shown in fig. 1, the refrigerating apparatus 30 may include an evaporator 31, a duct (not shown) and a wind tunnel 32 provided at an inner wall of the cabinet 20. The evaporator 31 is provided at the bottom inside the cabinet 20 and serves as a heat exchanger of the refrigerator to produce cool air. One end of the duct is connected to the evaporator 31 and the other end is connected to a first end of the air duct 32. And the cool air generated from the evaporator 31 can be sent into the duct 32. And the second end of the air duct 32 communicates with the air chamber, so that the cool air from the evaporator 31 in the air duct 32 can flow into the air chamber. Further, the duct and the duct 32 form an air supply passage for cooling the evaporator 31 into the air chamber.

Of course, a return air path may be provided in the box 20, and when the cold air generated by the evaporator 31 is sent into the air cavity, the air with higher temperature in the air cavity circulates to the evaporator 31 through the return air path, and then the evaporator 31 converts the air with higher temperature into the cold air, so as to form the air circulation inside the refrigerator.
