Detailed ways

The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

The traditional low-temperature preservation method only uses low temperature to reduce the respiration and enzyme activity of fruits, vegetables and other ingredients. The preservation time is short, and the cold air circulation causes fruits, vegetables and other ingredients to dehydrate severely. The preservation effect is not ideal and it is difficult to meet people's needs.

Based on this, the embodiment of the present application provides a fresh-keeping device and a refrigerator, which improves the fresh-keeping effect of food and prolongs the fresh-keeping time by setting an electromagnetic module and a humidifying device. Electromagnetic fresh-keeping is a new type of fresh-keeping technology. The electromagnetic field can not only inhibit the metabolism of fruits and vegetables and the activity of enzymes, but also control the growth and reproduction of microorganisms, achieve multi-dimensional fresh-keeping, and prevent the loss of food nutrients. At the same time, the humidifying device can replenish water to the food in time, effectively prevent the food from dehydrating, and thus maintain the freshness of the food.

Please refer to Figures 1 to 3, Figure 1 is a schematic diagram of the decomposed structure of the preservation device provided in an embodiment of the present application, Figure 2 is a schematic diagram of the structure of the preservation device provided in an embodiment of the present application from a first perspective, and Figure 3 is a schematic diagram of the cross-section of Figure 2 along the P1-P2 direction.

The embodiment of the present application provides a fresh-keeping device 100 , which includes a compartment body 10 , an electromagnetic module 20 and a humidifier 30 .

The compartment body 10 includes a shell 11, which is arranged to form a first storage space 111 for storing food. The shell 11 is also provided with an annular wall 12, which is arranged together with the shell 11 to form a second storage space 121; an electromagnetic module 20 is arranged in the second storage space 121, and the electromagnetic module 20 is configured to sterilize and preserve the food stored in the first storage space 111; a humidifier 30 is arranged in the first storage space 111, and the humidifier 30 is configured to replenish moisture to the food stored in the first storage space 111.

Exemplarily, the compartment body 10 is in the shape of a rectangular parallelepiped, and its interior is hollow to form a first accommodation space 111. One side of the compartment body 10 has an opening. The first accommodation space 111 can also be understood as a cavity for placing food. The food in the embodiment of the present application can be fruits, vegetables and other food that need to be kept fresh.

In the embodiment of the present application, an annular wall 12 is provided on the upper surface of the housing 11, and the annular wall 12 and the housing 11 are jointly arranged to form a second accommodating space 121, and the electromagnetic module 20 is arranged in the second accommodating space 121, and the electromagnetic module 20 is detachably connected to the housing 11. It should be noted that the housing 11 and the annular wall 12 can be an integrally formed structure, or can be formed by welding, gluing, etc.

Exemplarily, the annular wall 12 and the upper surface of the housing 11 are arranged to form a second accommodating space 121, and the size of the second accommodating space 121 matches the size of the electromagnetic module 20, so that the electromagnetic module 20 can be arranged in the second accommodating space 121. Preferably, the shape of the second accommodating space 121 and the shape of the electromagnetic module 20 are both circular, and the diameter of the electromagnetic module 20 is smaller than the diameter of the second accommodating space 121, so that the electromagnetic module 20 can be installed in the second accommodating space 121, and the height of the electromagnetic module 20 is smaller than the height of the annular wall 12.

It should be noted that the electromagnetic module 20 is arranged in the second accommodating space 121 on the upper side of the compartment body 10, and the vertical distance between the electromagnetic module 20 and the first accommodating space 111 is reduced. Therefore, the magnetic field generated by the electromagnetic module 20 can directly act on the first accommodating space 111, avoiding the attenuation of the magnetic field, and at the same time, a compact layout of the electromagnetic module 20 and the compartment body 10 can be achieved.

Please refer to Fig. 4, which is a schematic diagram of the structure of the electromagnetic module 20 shown in Fig. 1. The electromagnetic module 20 includes a first electromagnetic plate 22 and a second electromagnetic plate 23 arranged relatively parallel to each other, and the first electromagnetic plate 22 and the second electromagnetic plate 23 are formed with a first through hole 21 that penetrates therethrough.

The first electromagnetic plate 22 and the second electromagnetic plate 23 can be permanent magnets or electromagnets. The magnetic field generated by the permanent magnet has the effect of environmental protection and does not require external energy consumption. The magnetic field generated by the electromagnet is controllable, and the magnetic field strength can be controlled by adjusting factors such as voltage and current according to the needs of different types of food (such as cooked food, fruits and vegetables, meat, etc.).

Exemplarily, the first electromagnetic plate 22 is configured as an electromagnet, which is also called a Helmholtz coil. When a current passes through the coil, a magnetic field can be generated. By adjusting the magnitude of the current, the strength of the magnetic field can be controlled. The second electromagnetic plate 23 is configured as a permanent magnet, such as a magnet. The first electromagnetic plate 22 and the second electromagnetic plate 23 have opposite polarities and can attract each other. The second electromagnetic plate 23 has a magnetic conductivity. The first electromagnetic plate 22 and the second electromagnetic plate 23 cooperate to increase the strength of the electromagnetic field and improve the uniformity of the electromagnetic field, so as to improve the effect of electromagnetic preservation.

In some embodiments, the first electromagnetic plate 22 is configured as an electromagnet, i.e., a Helmholtz coil, and the second electromagnetic plate 23 is configured as an iron plate, which has a magnetic attraction effect. The first electromagnetic plate 22 and the second electromagnetic plate 23 are arranged in parallel, and the second electromagnetic plate 23 cooperates with the first electromagnetic plate 22 to improve the uniformity of the electromagnetic field generated by the first electromagnetic plate 22 and the electromagnetic preservation effect.

In some embodiments, the second electromagnetic plate 23 may also be made of other magnetically attractive materials, such as metals such as iron, cobalt, nickel, or alloys thereof.

In some embodiments, the first electromagnetic plate 22 and the second electromagnetic plate 23 are both configured as electromagnets, i.e., Helmholtz coils. The first electromagnetic plate 22 and the second electromagnetic plate 23 have opposite polarities and can produce a mutual attraction. By providing two electromagnets, the uniformity of the electromagnetic field can be improved to improve the effect of electromagnetic preservation.

It should be noted that the first electromagnetic plate 22 and the second electromagnetic plate 23 are arranged in parallel, and the smaller the distance between the first electromagnetic plate 22 and the second electromagnetic plate 23, the greater the magnetic field strength, but the magnetic field strength needs to be within a certain range to avoid interference with other components (for example, generating magnetic attraction to other components, etc.). The distance between the first electromagnetic plate 22 and the second electromagnetic plate 23 can be set to 5-15mm. Preferably, the distance between the first electromagnetic plate 22 and the second electromagnetic plate 23 is set to 10mm.

It should be noted that the electromagnetic module 20 can generate a magnetic field, which has good bactericidal and enzyme-inactivating effects. Appropriate magnetic field intensity can change the physical and chemical properties of biological macromolecules and cell membranes, effectively remove free radicals, improve the freshness of food, and extend the shelf life.

In the embodiment of the present application, the electromagnetic module 20 is arranged in the second accommodation space 121 on the upper side of the compartment body 10, so that the vertical distance between the electromagnetic module 20 and the first accommodation space 111 can be reduced. Therefore, the magnetic field generated by the electromagnetic module 20 directly acts on the first accommodation space 111 to avoid the attenuation of the magnetic field. The magnetic field generated by the electromagnetic module 20 can sterilize and preserve the food stored in the first accommodation space 111; at the same time, a compact layout of the electromagnetic module 20 and the compartment body 10 can be achieved.

Please continue to refer to Figures 1 to 3. In the embodiment of the present application, the fresh-keeping device 100 further includes a humidifier 30, which is disposed in the first accommodation space 111. The humidifier 30 is configured to replenish moisture to the food stored in the first accommodation space 111. By providing the humidifier 30, moisture can be replenished to the food in time to prevent the food from dehydration, thereby improving the fresh-keeping effect of the food.

It can be understood that the humidifier 30 is a miniature humidifier, and the humidifier 30 is disposed in the first accommodation space 111. The humidifier 30 can maintain the humidity of the first accommodation space 111, so that the humidity in the first accommodation space 111 reaches 90%-95%, so as to meet the need for food preservation and prevent food from dehydration.

The preservation device 100 provided in the embodiment of the present application can sterilize and preserve the food stored in the first storage space 111 by providing an electromagnetic module 20 and a humidifier 30, and can replenish water in time, effectively preventing the food from dehydrating, extending the shelf life of the food, and achieving the effect of maintaining the freshness of the food.

Please continue to refer to FIG. 1 to FIG. 3 . The fresh-keeping device 100 further includes a water tank 50 . The water tank 50 has a water storage function. The water tank 50 is connected to the humidifier 30 via a water delivery pipe 51 .

Exemplarily, the water tank 50 is disposed on a side of the electromagnetic module 20 away from the compartment body 10, and the water tank 50 is connected to the humidifier 30 through a water delivery pipe 51, and the water delivery pipe 51 passes through the electromagnetic module 20 and the housing 11, and extends into the first accommodation space 111 to be connected to the humidifier 30. It can be understood that the water delivery pipe 51 connects the water tank 50 and the humidifier 30.

Preferably, the water tank 50 is connected to the water vapor circulation system inside the refrigerator, and the condensed water inside the refrigerator can flow into the water tank 50 through the water vapor circulation system, thereby realizing the secondary utilization of the condensed water.

In some embodiments, the fresh-keeping device 100 further includes a cover plate 40, which is connected to the annular wall 12, so that the cover plate 40, the annular wall 12, and the shell 11 are jointly arranged to form a second accommodating space 121, and the electromagnetic module 20 is arranged in the second accommodating space 121 to achieve a compact layout of the electromagnetic module 20, the compartment body 10, and the cover plate 40.

Exemplarily, the cover plate 40 includes a top cover 42 and a side wall 43, and the top cover 42 and the side wall 43 are an integrally formed structure. The top cover 42 is disposed on the opening of the second accommodation space 121 formed by the annular wall 12 and the housing 11, and the side wall 43 is sleeved on the outer periphery of the annular wall 12 and snap-connected with the annular wall 12, so that the cover plate 40, the annular wall 12 and the housing 11 are jointly enclosed to form a sealed second accommodation space 121.

In practical applications, the electromagnetic module 20 is detachably connected to the compartment body 10, and after the electromagnetic module 20 is installed in the second accommodation space 121, the cover plate 40 is covered. The top cover 42 matches the opening of the second accommodation space 121, and the side wall 43 is sleeved on the outer periphery of the annular wall 12 and snap-connected with the annular wall 12, so that the electromagnetic module 20 is located in the sealed second accommodation space 121. It can be understood that the electromagnetic module 20 is arranged on the upper side of the compartment body 10, and the magnetic field generated by the electromagnetic module 20 can directly act on the first accommodation space 111.

In some embodiments, the water tank 50 is disposed on a side of the cover plate 40 away from the electromagnetic module 20, and the water supply pipe 51 needs to pass through the cover plate 40, the electromagnetic module 20 and the shell 11, and extend into the first storage space 111 to connect with the humidifier 30 to replenish moisture for the food stored in the first storage space 111.

Exemplarily, the cover plate 40 may be provided with a second through hole 41, the electromagnetic module 20 may be provided with a first through hole 21, the water delivery pipe 51 vertically passes through the first through hole 21 and the second through hole 41, and extends into the first accommodation space 111 to connect with the humidifier 30. Since the water delivery pipe 51 can vertically pass through the first through hole 21 and the second through hole 41, the length of the water delivery pipe 51 between the water tank 50 and the humidifier 30 is shortened.

In addition, considering that the humidity in the first storage space 111 is high and the temperature of the inner wall of the compartment body 10 is low, water droplets will condense on the surface of the food and the inner wall of the compartment body 10, causing water accumulation in the first storage space 111. To solve this problem, a hollow structure can be provided at the bottom of the compartment body 10 for water permeability. The bottom of the compartment body 10 can be connected to the water vapor circulation system of the refrigerator, and the condensed water in the compartment body 10 can flow into the water tank 50 through the water vapor circulation system, thereby realizing the secondary utilization of the condensed water.

Please refer to Figures 5 to 7, Figure 5 is a structural schematic diagram of the second perspective of the fresh-keeping device provided in an embodiment of the present application, Figure 6 is a partial enlarged view of part A in Figure 5, and Figure 7 is a partial enlarged view of part B in Figure 5.

In some embodiments, the fresh-keeping device 100 further includes a temperature sensor 60 and a humidity sensor 70. The temperature sensor 60 is connected to the compartment body 10 to detect the temperature of the first receiving space 111; the humidity sensor 70 is connected to the compartment body 10 to detect the humidity of the first receiving space 111.

Exemplarily, a first groove 112 for accommodating the temperature sensor 60 is provided on the first side wall 118 of the compartment body 10, the first groove 112 is away from the opening direction of the compartment body 10, and the periphery of the first groove 112 extends a first limit portion 113 and a second limit portion 114, and the first limit portion 113 and the second limit portion 114 are arranged opposite to each other. The number of the first limit portion 113 and the second limit portion 114 can be one, two or more, and the embodiment of the present application does not limit the number of the first limit portion 113 and the second limit portion 114, and it is only necessary to make the number of the first limit portion 113 consistent with the number of the second limit portion 114.

When the temperature sensor 60 is located in the first groove 112 , the first limiting portion 113 and the second limiting portion 114 can limit the temperature sensor 60 to prevent the temperature sensor 60 from falling out of the first groove 112 .

It should be noted that a through hole is provided on the groove wall of the first groove 112, and the first groove 112 is connected to the first accommodating space 111. The temperature sensor 60 can detect the temperature of the first accommodating space 111 to ensure that the temperature in the first space meets the food storage temperature requirement.

In some other embodiments, the temperature sensor 60 is disposed near the electromagnetic module 20, and the temperature sensor 60 can detect not only the temperature of the first accommodation space 111, but also the temperature of the second accommodation space 121. Since the electromagnetic module 20 generates a certain degree of heat when generating a magnetic field, in order to prevent the heat of the electromagnetic module 20 from affecting the refrigeration, when the temperature detected by the temperature sensor 60 exceeds the preset protection temperature, the electromagnetic module 20 is controlled to be powered off, thereby achieving overheat protection.

Exemplarily, a second groove 115 for accommodating the humidity sensor 70 is provided on the first side wall 118 of the compartment body 10, the second groove 115 is away from the opening direction of the compartment body 10, and the periphery of the second groove 115 extends a third limiting portion 116 and a fourth limiting portion 117, and the third limiting portion 116 and the fourth limiting portion 117 are arranged opposite to each other. The number of the third limiting portion 116 and the fourth limiting portion 117 can be one, two or more, and the embodiment of the present application does not limit the number of the third limiting portion 116 and the fourth limiting portion 117, and it is only necessary to make the number of the third limiting portion 116 and the number of the fourth limiting portion 117 consistent.

When the humidity sensor 70 is located in the second groove 115 , the third limiting portion 116 and the fourth limiting portion 117 can limit the humidity sensor 70 to prevent the humidity sensor 70 from falling out of the second groove 115 .

It should be noted that a through hole is provided on the groove wall of the second groove 115, and the second groove 115 is connected to the first receiving space 111. The humidity sensor 70 can detect the humidity of the first receiving space 111 to ensure that the humidity in the first space meets the food storage humidity requirement.

When the humidity sensor 70 detects that the humidity of the first storage space 111 is lower than the preset humidity, the humidifier 30 is controlled to add moisture into the first storage space 111 to meet the need of preserving the food and prevent the food from dehydrating.

Please refer to FIG8 in conjunction with FIG1 . FIG8 is a schematic diagram of the exploded structure of a fresh-keeping device 100 provided in another embodiment of the present application.

In some embodiments, the fresh-keeping device 100 further includes an air duct 80, which is configured to transport cold air, and the cold air can be transported to the first accommodation space 111 and the second accommodation space 121. The air duct 80 is opposite to the first side wall 118 of the compartment body 10, and it can be understood that the air duct 80 is arranged on the side away from the opening of the compartment body 10. An air vent 122 is arranged on the first side wall 118 of the compartment body 10 facing the air duct 80, and the air vent 122 is connected to the first accommodation space 111 and the second accommodation space 121, and the air vent 122 is connected to the air duct 80. It can be understood that the air duct 80 is interconnected with the cold air circulation system of the refrigerator, and the cold air circulation system is also interconnected with the first accommodation space 111 and the second accommodation space 121.

It should be noted that since the heat generated by the electromagnetic module 20 can increase the temperature of the first storage space 111 and the second storage space 121, which is not conducive to the preservation of food, in order to keep the temperature constant, cold air needs to circulate in the first storage space 111 and the second storage space 121 to take away the heat generated by the electromagnetic module 20.

The cold air circulation process will take away some moisture, reducing the humidity of the first storage space 111. When the humidity sensor 70 detects that the humidity of the first storage space 111 is lower than the preset humidity, the humidifier 30 is controlled to add moisture to the first storage space 111 to meet the food preservation needs and prevent the food from dehydration.

Please continue to refer to FIG8 .

Food can be placed in the drawer 90, and the drawer 90 can be understood as a cavity for placing food.

In some embodiments, a sealing gasket 91 is further provided between the compartment body 10 and the front panel of the drawer 90, for sealing between the compartment body 10 and the front panel of the drawer 90 when the drawer 90 is closed. The sealing gasket 91 is made of latex, silicone, etc., for ensuring the airtightness of the food placement cavity.
