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 described embodiments are merely exemplary of some, and not all, of the present application. 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 refrigerator to improve the fresh-keeping effect of the refrigerator using electromagnetism for fresh keeping. The following description will be made with reference to the accompanying drawings.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a box body in the refrigerator shown in fig. 1. The refrigerator 00 may include a cabinet 10 and a door 20. The cabinet 10 is rotatably connected to the door 20, such that the door 20 can rotate relative to the cabinet 10 to open or close the cabinet 10. It is understood that the structure of the refrigerator 00 is not limited thereto, and may further include other components, such as shelves (not shown) which may be provided in the cabinet 10 for shelving items.
The box body 10 has a storage space 100, and the storage space 100 is used for accommodating articles to be refrigerated or frozen, such as ice cream, fish, vegetables and fruits, or unsealed cosmetics. When the door 20 rotates relative to the box body 10 until the door 20 opens the box body 10, the storage space 100 is exposed, and a user can store articles to be preserved in the storage space 100 or take out the preserved articles from the storage space 100; when the door 20 rotates relative to the box 10 to close the box 10, the storage space 100 is hidden, and the refrigerator 00 can perform cold storage or freezing storage on the articles to be kept fresh in the storage space 100.
It should be noted that the conventional refrigerator only creates a low temperature environment to inhibit the respiration of the fresh sample, the activity of various enzymes in the fresh sample and the growth and reproduction of various microorganisms, so as to keep the stored articles in the refrigerator fresh. However, the drawbacks of the conventional refrigerator are also very significant: in the refrigeration mode, the food is in an unfrozen state, which is convenient for a user to quickly process (for example, unfrozen meat is convenient to cut), but the preservation time is short; in the freezing mode, the food is in the frozen state, and although the fresh-keeping time is long, the food is inconvenient for the user to quickly handle (for example, frozen meat cannot be cut).
With the development of science and technology, novel preservation technologies such as air conditioning, negative ions and electromagnetism are applied to the refrigerator, and the defects of the traditional refrigerator can be overcome by matching the novel preservation technologies with the low-temperature preservation technologies. However, due to the immaturity of the technology, the problem that the preservation effect of the refrigerator is poor still exists in the novel preservation technology, particularly the electromagnetic preservation refrigerator, and the refrigerator 00 provided by the embodiment of the application can improve the preservation effect of the refrigerator by utilizing the electromagnetic preservation.

The container body 30 is disposed in the box body 10 and used for placing articles to be preserved. Specifically, the container body 30 may be disposed in the storage space 100 of the box 10, and the container body 30 itself has a receiving cavity, which may be used for receiving the articles to be preserved.
The container body 30 may be a drawer type structure. For example, the container body 30 may include a sleeve (not shown) having an opening and a drawer (not shown) drawably disposed in the sleeve to open or close the opening. The container body 30 may also be a box (not shown) with an opening, through which a user can place or remove the fresh-keeping articles into or from the box. The embodiment of the present application does not limit the specific form of the container body 30.
The container body 30 may be made of plastic material, such as white or colorless plastic. The container body 30 may also be made of organic glass, such as clear acrylic. This application embodiment does not do the restriction to the concrete material of vessel 30, specific colour and whether transparent, but can understand, sets up vessel 30 into transparent material, carries out the classification to the article that need keep fresh when more being convenient for the user places the article that need keep fresh in vessel 30 and the user takes out the article that has kept fresh from vessel 30.

Specifically, the identification component 40 may be disposed on an inner wall of the container 10 or directly disposed within the container body 30. It can be understood that, compared with the case body 10 having the identification component 40 disposed on the inner wall thereof, the identification component 40 is directly disposed in the container body 30, so that the identification efficiency and the identification accuracy of the identification component 40 for identifying the articles to be preserved can be improved. It should be noted, however, that if container body 30 is opaque, identification component 40 must be at least partially disposed within container body 30.
The electromagnetic assembly 50 is disposed in the box body 10, and is configured to generate magnetic fields with different parameters in the container body 30 according to the type and freshness of the articles to be kept fresh placed in the container body 30. The parameters of the magnetic field may include at least one of the parameters of the kind of the magnetic field, the intensity of the magnetic field, and the frequency of the magnetic field. It can be understood that different types of articles need different fresh-keeping conditions, and the same type of articles need different fresh-keeping conditions at different freshness degrees, and if the parameters of the magnetic field are not suitable, the articles need to be kept fresh cannot be properly kept fresh. Therefore, the parameters of the magnetic field generated by the electromagnetic assembly 50 in the container body 30 need to be adjusted according to the type and freshness of the articles to be kept fresh placed in the container body 30.
In the refrigerator 00 provided by the embodiment of the application, the container body 30 is arranged in the box body 10 of the refrigerator 00 and used for placing articles needing to be preserved, the type and the freshness degree of the articles needing to be preserved placed in the container body 30 are identified through the identification component 40 arranged in the box body 10 of the refrigerator 00, and the electromagnetic component 50 arranged in the box body 10 of the refrigerator 00 generates magnetic fields with different parameters in the container body 30 according to the type and the freshness degree of the articles needing to be preserved placed in the container body 30 to realize preservation, so that the parameters of the magnetic fields in the container body 30 are different along with the difference between the type and the freshness degree of the articles needing to be preserved placed in the container body 30, and further, the preservation effect of the refrigerator 00 using electromagnetism for preservation is improved.
Please continue to refer to fig. 3. Refrigerator 00 may include a cabinet 10, a door 20, a container body 30, an identification assembly 40, and an electromagnetic assembly 50. Wherein, the recognition component 40 may include a storage device 41, an image capturing device 42, and a recognition device 43; the solenoid assembly 50 may include an excitation device 51 and a control device 52. The specific structures of the recognition assembly 40 and the electromagnetic assembly 50 are described below, respectively.
The identification component 40 can include:
a storage device 41, the storage device 41 being used for storing data required by the identification component 40 and data generated during operation of the identification component 40. The storage device 41 stores picture information of various articles to be preserved in different freshness degrees. For example, the storage device 41 stores picture information of vegetables such as chinese cabbage, and leaf lettuce in different freshness degrees, the storage device 41 also stores picture information of fruits such as banana, mango, and watermelon in different freshness degrees, and the storage device 41 also stores picture information of meat such as meat, fish, and shrimp or seafood in different freshness degrees.
The camera device 42 is used for shooting the photo information of the article to be preserved placed in the container body 30 so that the identification component 40 can obtain the information of the article to be preserved placed in the container body 30. The picture information of the article to be preserved, which is taken by the camera device 42 and is placed in the container body 30, is data generated in the working process of the identification component 40, and needs to be stored in the storage device 41, so that the camera device 42 needs to be electrically connected with the storage device 41.
The identification device 43, the identification device 43 is used for identifying the type and freshness of the articles to be preserved placed in the container body 30. Specifically, the identification device 43 can determine what kind and freshness of the articles to be kept fresh are placed in the container body 30 by comparing the picture information captured by the imaging device 42 with the picture information stored in the storage device 41. Since the recognition device 43 needs to call the photo information and the picture information, the recognition device 43 needs to be electrically connected to the storage device 41.
The solenoid assembly 50 may include:
and an exciting device 51, wherein the exciting device 51 is used for generating a magnetic field in the container body 30. Excitation device 51 may be an excitation coil, such as an excitation coil with 100-. It is understood that if the excitation device 51 is a permanent magnet, the excitation device 51 cannot generate a uniform magnetic field, and the magnetic properties of the permanent magnet deteriorate with time. By using the exciting coil as the exciting device 51, the parameters of the magnetic field generated by the exciting device 51 can be controlled by controlling the number of turns of the exciting coil and the magnitude and direction of the current in the coil. Such as: when direct current is passed through the exciting coil, the magnetic field generated by the exciting device 51 is a static magnetic field; when an alternating current is passed through the exciting coil, the magnetic field generated by the exciting device 51 is an alternating magnetic field, and the frequency of the alternating magnetic field can be controlled to be 50-100 Hz.
A control device 52, wherein the control device 52 is used for controlling the intensity of the magnetic field generated by the excitation device 51 according to the type and freshness of the articles to be preserved placed in the container body 30. The control device 52 is electrically connected to the identification device 43 and the excitation device 51, so that the control device 52 controls the excitation device 51 to generate magnetic fields with different intensities according to different types and different freshness of the articles to be preserved identified by the identification device 43.
Referring to fig. 3 and 4, fig. 4 is a diagram illustrating parameters for controlling the magnetic field and the temperature in different container bodies of a refrigerator according to an embodiment of the present disclosure. The refrigerator 00 may include a plurality of container bodies 30, and different types of articles to be kept fresh may be placed in different container bodies 30. For example, vegetables and fruits can be placed in the vegetable room, and meat and seafood can be placed in the meat room. When the identification device 43 identifies that the articles to be preserved in the container body 30 are vegetables, the control device 52 controls the excitation device 51 to generate a magnetic field with the strength of 1mT to 5mT in the container body 30; when the identification device 43 identifies that the articles to be preserved placed in the container body 30 are fruits, the control device 52 controls the excitation device 51 to generate a magnetic field with the intensity of 1.2mT to 10mT in the container body 30; when the identification device 43 identifies that the articles to be preserved placed in the container body 30 are meat or seafood, the control device 52 controls the excitation device 51 to generate a magnetic field with the strength of 1mT to 20mT in the container body 30.
It should be noted that the shape of the meat does not change significantly during storage, but ammonia gas is generated during storage of the meat, and as the storage time increases, the more ammonia gas is generated, the higher the concentration of ammonia gas in the container body 30 becomes. Therefore, in some embodiments, in order to increase the identification accuracy of the identification device 43 for identifying the freshness of the meat, the identification assembly 40 may further comprise a gas detection device 44. The gas detection device 44 is electrically connected to the identification device 43, and when the identification device 43 identifies that the articles to be preserved placed in the container body 30 are meat or seafood, the concentration of the ammonia gas in the container body 30 is detected, so that the identification assembly 40 can more accurately identify the freshness of the meat or seafood placed in the container body 30.

The refrigerator 00 may set the first threshold value and the second threshold value in advance. Wherein the first threshold value is less than the second threshold value, the first threshold value being indicative of a concentration of the ammonia-based gas within the container body 30 that is less than the concentration of the ammonia-based gas within the container body 30 that is indicative of the second threshold value. When the gas detector 44 detects that the concentration of the ammonia gas in the container main body 30 is equal to or lower than the first threshold value, the controller 52 controls the exciter 51 to generate a magnetic field having a strength of 1mT to 10mT in the container main body 30; when the gas detector 44 detects that the concentration of the ammonia gas in the container main body 30 is higher than the first threshold value and lower than or equal to the second threshold value, the controller 52 controls the exciter 51 to generate a magnetic field with a strength of 5mT-20mT in the container main body 30; when the gas detector 44 detects that the concentration of the ammonia gas in the container main body 30 is higher than the second threshold value, the controller 52 controls the exciter 51 to generate a magnetic field having a strength of 10mT to 20mT in the container main body 30.
The gas detecting device 44 may first measure the initial content T of the ammonia-based gas in the container body 300Then measuring the current content T of the ammonia gas in the container body 30, the current content T and the initial content T0The difference of the initial content T0The ratio of (A) to (B) is the concentration of the ammonia-based gas in the container body 30, i.e., (T-T)0)/T0. The first threshold may be 20%, and the second threshold may be 50%. It should be noted that the first threshold and the second threshold may also be other values, and the first threshold and the second threshold are set in the embodiments of the present applicationThe volume value is not limited.
It should be noted that, in the storage process, along with the decrease of the freshness of the articles to be kept fresh placed in the container body 30, the control device 52 may control the increase of the strength of the magnetic field generated by the excitation device 51, so that the strength of the magnetic field in the container body 30 is increased along with the decrease of the freshness of the articles to be kept fresh placed in the container body 30, thereby further improving the preservation effect of the refrigerator 00.
