Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a fresh-keeping drawer and a control method thereof, and a refrigerator. Background Art

[0002] As the pace of life accelerates, consumers buy less and less fruits and vegetables, and their purchasing habits change from buying small quantities and multiple times to buying large quantities and fewer times, which puts higher demands on the freshness preservation ability of refrigerators. Low temperature and high humidity play an important role in extending the shelf life of fruits and vegetables. However, high humidity is also conducive to the growth of microorganisms, which will cause fruits and vegetables to rot and produce odors. For example, rotting vegetables will produce trimethylamine, and fermented fruits will produce ethanol, which seriously affects the internal environment of the refrigerator. Therefore, it is very important to effectively sterilize the storage environment of fruits and vegetables.

[0003] There are many forms of sterilization methods on the market, and their sterilization effects vary greatly. They are also not able to adjust the sterilization and odor removal abilities according to the real-time status of the stored food. When fruits and vegetables are in good condition, sterilization may cause side effects to them. When fruits and vegetables are in poor condition, the preset sterilization methods are not enough to completely sterilize them. On the other hand, when stored food rots or molds, users cannot take them out in time, which will contaminate other food and cause the entire refrigerator compartment to be filled with odors, which is difficult to deal with.

[0034] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] In a preferred embodiment 1 of the present invention, a fresh-keeping drawer is provided, which can be applied to various types of refrigerators to achieve fresh-keeping of refrigerators. Specifically, Figure 1 An optional structural schematic diagram of a refrigerator with the fresh-keeping drawer is shown. Figure 1 As shown, the drawer body of the fresh-keeping drawer is located on the first layer of the refrigerator and is used to keep items fresh.

[0037] Figure 2 An optional structural diagram of the fresh-keeping drawer is shown in FIG. Figure 2 As shown, the fresh-keeping drawer includes:

[0038] Drawer body 1;

[0040] The detection device 3 is located in the drawer body 1 and is used to detect environmental parameters of the environment in the drawer body 1;

[0041] The controller is connected to the detection device 3 at one end and to the purification device at the other end, and is used to determine the purification gear of the purification device according to the environmental parameters of the environment in the drawer body 1, so as to purify the environment in the drawer body 1; wherein the purification gear of the purification device includes multiple gears, and each purification gear corresponds to opening a different type and / or number of sterilization and deodorization devices. A purification device with multiple gears is equivalent to having multiple purification modes, and can perform targeted sterilization and deodorization in the fresh-keeping drawer.

[0042] In the above embodiment, a fresh-keeping drawer is provided, including a drawer body and a purification device for purifying the environment inside the drawer body, wherein the purification device includes various types of sterilization and deodorization devices, and when the environmental parameters of the environment inside the drawer body are different, different purification gears are turned on to purify the environment inside the drawer body.

[0043] The purification device in the present invention includes multiple types of sterilization and deodorization devices, and the number of each type of sterilization and deodorization device is at least one; Figure 2 As shown, the sterilization and deodorization device at least includes: an atmosphere-adjusting device, which includes an atmosphere-adjusting membrane 2, which is located on the upper panel of the drawer body 1 and is used to adjust the gas concentration in the environment of the drawer body 1. The atmosphere-adjusting membrane 2 can adjust the humidity in the drawer body 1, and can also adjust the gas concentration in the drawer body 1, mainly including the concentration of oxygen and carbon dioxide that affect the storage effect of fruits and vegetables and other food materials. The atmosphere-adjusting membrane 2 performs preliminary passive adjustment on the environment in the drawer to maintain the gas environment in the drawer.

Compared with the modified atmosphere membrane 2, the pulsed electric field is an active purification method, which has a more obvious purification effect on the environment inside the drawer, and can further improve the fresh-keeping environment inside the drawer.

[0045] Figure 3 Another optional structural schematic diagram of the fresh-keeping drawer is shown. Figure 3 This is the rear view of the fresh-keeping drawer. Figure 3 As shown, the fresh-keeping drawer is provided with an interlayer at the rear of the fresh-keeping body, and the interlayer is connected to the internal environment of the fresh-keeping body through a damper; the damper may include two or more dampers, such as Figure 3 As shown, it includes a first air door 7 and a second air door 8, so that the environment inside the drawer body 1 can circulate gas with the interlayer.

[0046] like Figure 3 As shown, the sterilization and deodorization device at least includes: a photocatalyst device 10, which is located in the interlayer and is used to sterilize the internal environment of the fresh-keeping body through a photocatalyst material. Photocatalyst materials can produce strong oxidizing substances under light irradiation, and can be used to decompose organic compounds, some inorganic compounds, bacteria and viruses, etc., and can effectively degrade toxic and harmful gases in the air such as formaldehyde, and efficiently purify the air. At the same time, it can effectively kill a variety of bacteria. In addition, a first fan 9 is also provided, which is located in the interlayer and is used to accelerate the flow of gas in the interlayer, thereby accelerating gas purification. The photocatalyst device 10 can further enhance the sterilization effect of the fresh-keeping drawer in the present invention and ensure the suitability of the environment in the fresh-keeping drawer.

[0047] Furthermore, if Figure 3 As shown, the sterilization and deodorization device at least includes: a fresh air duct 11, one end of which is connected to the interlayer and the other end is connected to the outdoor environment, and is used to ventilate the internal environment of the fresh-keeping body through outdoor fresh air. Figure 3 As shown, the fresh air duct 11 includes two, which are connected to the interlayer through the third damper 14 and the fourth damper 15 located on the interlayer. A second fan 13 is arranged in the duct to accelerate the gas flow in the fresh air duct 11, and a deodorizing device 12 is arranged to purify the air in the fresh air duct 11. There are two second fans 13, and the fans in the two air ducts can have opposite air outlet directions. When all four dampers are opened and the fans are running at the same time, the gas inside the drawer can be extracted and fresh air can be introduced at the same time to achieve thorough purification.

[0048] Preferably, the detection device 3 at least includes: a temperature and humidity sensor for detecting the temperature and humidity parameters of the environment inside the fresh-keeping body; a gas concentration sensor for detecting the gas concentration of the environment inside the fresh-keeping body, wherein the gas concentration at least includes: ethylene concentration, methyl mercaptan concentration, and ethanol concentration. The above-mentioned gas concentration may also include other gas concentrations as long as they are used to characterize the environment inside the drawer. The above-mentioned gas concentration accurately reflects the quality of the environment inside the drawer, and then executes the corresponding purification gear or purification mode to achieve accurate purification.

[0049] Furthermore, if Figure 2As shown, the fresh-keeping drawer also includes: a camera device 5, located on the upper panel of the drawer body 1, for obtaining the food in the fresh-keeping drawer; wherein the controller is also used to predict the fresh-keeping period of the food according to the type of food and the environmental parameters of the environment in the drawer body 1; a display panel 4, located on the front panel of the drawer body 1, for displaying the fresh-keeping period of the food, and the purification gear of the purification device. The camera can be set at the lighting lamp on the top of the fresh-keeping drawer, and the sensor can be placed at the same time to monitor the changes in temperature and humidity and various gases (ethylene, methyl mercaptan, ethanol) in the compartment in real time, and transmit it to the controller, and combine various storage food preservation models to infer the fresh-keeping period of various food and feedback on the operation panel. The camera can also monitor the corrosion of the food. For example, when the camera recognizes obvious moldy or rotten food, the buzzer alarms every 15 minutes, and the operation panel reminds the user to take out the rotten and moldy food.

[0050] In the present invention, by adopting the structural design of setting up interlayer and fresh air duct in the drawer, and carrying multiple sterilization and deodorization components (pulse electric field, photocatalyst, deodorization, fresh air) in linkage mode, the sterilization power can be adjusted in time according to the specific conditions of the food and the changes in the room environment, so as to achieve the effect of energy saving and reducing the side effects on the food. At the same time, the shelf life of the stored food can be inferred by combining intelligent sensors with data big model calculation, and the mold and rot of the food can be monitored at the same time, and the multi-speed sterilization and deodorization mode can be used to achieve the effect of long-term cleanliness and odorlessness of the food storage space.

Through the purification device in the present invention, various modes of sterilization and deodorization effects are achieved, and the purification method is adjusted in time according to the different gas concentrations and changes in gas concentrations in the fresh-keeping drawer, and sterilization and deodorization are carried out in a targeted manner, effectively inhibiting the deterioration of the environment in the fresh-keeping drawer and the mold and decay of food, extending the shelf life of food, and improving the fresh-keeping effect of the fresh-keeping drawer and the refrigerator. Furthermore, the sterilization and deodorization device at least includes: an atmosphere control device, and the atmosphere control device includes an atmosphere control membrane, which is located on the upper panel of the drawer body and is used to adjust the gas concentration of the internal environment of the drawer body.
