DETAILED DESCRIPTION

[0033] In order for those skilled in the art to better understand the technical solutions in the present application, 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 some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0034] The existing refrigerator space layout is not reasonable enough, and cannot meet the classification storage needs of various food materials, which is easy to cause food odor mixing, and the temperature control is not fine and accurate enough, it is difficult to provide the best storage temperature for different food materials, which affects the food preservation effect. In addition, there is a lack of independent storage space and suitable environment specially for special food materials such as maternal and infant food, cosmetics, medicine, etc.

[0035] The multi-door fresh-keeping refrigerator provided by the present application effectively prolongs the preservation period of food through accurate temperature control and suitable storage environment; multiple independent storage compartments and flexible internal space layout enable different types of food and special food materials to be stored in a classified manner, avoiding mutual odor mixing; it can meet the special needs of users, such as setting up a maternal and infant area and a medicine and cosmetics area, to ensure the quality and safety of special items; in addition, since each compartment is independently temperature-controlled, energy waste caused by overall refrigeration or heating can be avoided, which conforms to the development trend of energy saving and environmental protection.

[0036] The specific structure of the multi-compartment fresh-keeping refrigerator provided by the present application will be described in detail below in conjunction with the drawings.

[0037] Referring to Figures 1-6 As shown in the drawings, the embodiments of the present application provide a multi-compartment fresh-keeping refrigerator, which comprises a refrigerator body 10 and a main control system 80 arranged on the refrigerator body 10. The refrigerator body 10 can be a rectangular box body of a conventional refrigerator, and the main control system 80 can be a conventional control system.

[0038] The refrigerator body 10 is provided with a refrigeration chamber 11, a freezing chamber 12 and multiple fresh-keeping interval chambers 13, such as Figure 1As shown, the refrigerator body 10 includes an upper part and a lower part. The left side of the upper part has a refrigerator compartment 11, and the right side of the upper part has a freezer compartment 12. The lower part of the refrigerator body 10 has multiple fresh-keeping compartments 13, with six fresh-keeping compartments 13 arranged in three layers. The number and location of the refrigerator compartment 11, the freezer compartment 12, and the multiple fresh-keeping compartments 13 are not specifically limited.

[0039] Each of the fresh-keeping compartments 13 is equipped with an air damper 14, a temperature sensor and a temperature control system. The main control system 80 is electrically connected to the temperature control system and the temperature sensor respectively. The temperature control system is electrically connected to the air damper 14 in the same fresh-keeping compartment 13.

[0040] A conventional temperature control system consists of a control circuit, a refrigeration system, a display and setting device, and an alarm device. The control circuit is the "brain" of the temperature control system. It receives signals from the temperature sensor, compares them with the set temperature, and then issues control commands based on the deviation to adjust the operation of the refrigeration system. The refrigeration system consists of a compressor, condenser, evaporator, and air ducts. The compressor compresses the refrigerant, causing it to liquefy in the condenser and then vaporize in the evaporator, achieving refrigeration. The control circuit regulates the cooling capacity by controlling the compressor's start / stop and operating frequency to reach the set temperature. The display and setting device shows the current temperature of the refrigerator, allowing users to set their desired temperature. Some smart refrigerators also support remote control and temperature adjustment via a mobile app. The alarm device will sound an alarm when the temperature inside the refrigerator is abnormal, such as a refrigeration system malfunction causing the temperature to be too high or too low, reminding the user to take timely action.

[0041] In this application, in order to save space, all compartments of the refrigerator can share one or more refrigeration systems. The air ducts of the refrigeration system connect each compartment. Each compartment is equipped with a damper 14 and a control circuit. The control circuit controls the state of the damper 14 in the same compartment. The state of the damper 14 includes an open state and a closed state. The open state includes multiple damper opening degrees, such as half open, fully open, etc.

[0042] When the refrigerator is working, the temperature sensor monitors the temperature of the fresh food compartment 13 and transmits it to the main control system 80. The main control system 80 compares the set temperature with the actual temperature of the corresponding compartment and sends instructions to the temperature control system. The instructions include raising the temperature, lowering the temperature, and maintaining the temperature. The temperature control system responds to the instructions by controlling the state of the damper 14 to adjust the temperature of the fresh food compartment 13 where the damper is located.

[0043] The multi-chamber fresh-keeping refrigerator provided by the embodiments of the present application is equipped with an independent temperature control system for each fresh-keeping chamber, thereby realizing accurate temperature control of different food materials, breaking through the limitation of overall temperature control or simple partition temperature control of a traditional refrigerator, effectively prolonging the fresh-keeping period of various food materials, and improving the user experience.

[0045] In some embodiments, the fresh-keeping chamber 13 is provided in a structure of a single door and a single drawer, and the adjustable temperature range of the plurality of independently temperature-controlled fresh-keeping chambers 13 is controlled within 10-14℃ and -16-2℃. The optional temperature range of the single independently temperature-controlled fresh-keeping chamber 13 includes micro-cold, ice temperature, micro-frozen, soft-frozen, and two-star frozen. The micro-cold is controlled at 10-14℃, the ice temperature is controlled at -1-1℃, the micro-frozen is controlled at -5- -2℃, the soft-frozen is controlled at -6- -9℃, the two-star frozen is controlled at -12- -16℃, and the temperature fluctuation of the independently temperature-controlled fresh-keeping chamber 13 is controlled within ±2℃.

[0046] Preferably, the single independently temperature-controlled fresh-keeping chamber 13 can be set to any one of the temperature ranges of micro-cold, ice temperature, micro-frozen, soft-frozen, and two-star frozen, or at least two independently temperature-controlled fresh-keeping chambers 13 can be set to the same temperature range.

[0047] Preferably, any one of the independently temperature-controlled fresh-keeping chambers 13 can be set as a medicine and cosmetics area, the temperature of the medicine and cosmetics area is controlled at 10-14℃, the medicine and cosmetics area has good sealing performance, and a humidity adjusting device is installed to maintain appropriate humidity in the area to prevent the medicine from being damp.

[0048] Preferably, any one of the independently temperature-controlled fresh-keeping chambers 13 can be set as a seafood area, the temperature of the seafood area is controlled at -1-1℃, and the seafood area has a detachable partition to meet the demand of adjusting the space size for storing food materials of different specifications.

[0049] Preferably, any one of the independently temperature-controlled fresh-keeping chambers 13 can be set as a thawing area, the temperature of the thawing area is controlled at -5- -2℃, and the thawing area uses air disturbance technology and a uniform cold plate to accurately control the temperature, so that the food material to be thawed can be quickly and non-destructively thawed to a micro-frozen state at about -3.5℃.

[0050] Reference Figure 3As shown, in some embodiments, the refrigerator body 10 is provided with an adjustable cabin 15, and a plurality of temperature insulation plates 20 are detachably arranged in the adjustable cabin 15.

The adjustable cabin 15 is a rectangular cabin, and two temperature insulation plates 20 are horizontally arranged in the adjustable cabin 15. The two temperature insulation plates 20 divide one adjustable cabin 15 into three fresh-keeping compartments 13, so that the refrigerator has six fresh-keeping compartments 13.

[0052] Further, referring to Figures 3-6 As shown, in some embodiments, in order to adjust the number and space size of the fresh-keeping compartments 13 according to actual needs, the fresh-keeping compartments 13 are designed to be detachable.

[0053] Specifically, the inner wall of the adjustable cabin 15 is provided with a connecting groove 16. The connecting groove 16 is horizontally arranged and is concave. The connecting groove 16 starts from one side of the open end of the adjustable cabin 15 and ends at the other side of the open end of the adjustable cabin 15.

[0056] The upper surface and the lower surface of the connecting groove 16 clamp the temperature insulation plate 20 and the elastic sealing strip 30. The lower surface of the elastic sealing strip 30 is in close contact with the lower surface of the connecting groove 16, so as to avoid the influence of the temperature of the adjacent fresh-keeping compartments 13.

[0057] Referring to Figure 6 As shown, in some embodiments, in order to stably fix the temperature insulation plate 20, the inner wall of the connecting groove 16 is provided with a limiting groove 17. The limiting groove 17 can be a circular groove or a square groove, and is horizontally arranged. The open end of the limiting groove 17 faces the fresh-keeping compartment 13.

[0058] The side wall of the temperature insulation plate 20 is provided with a blind hole 21. The blind hole 21 can be a circular hole or a square hole. A limiting rod 22 is inserted into the blind hole 21. The limiting rod 22 is matched with the limiting groove 17. An elastic member 23 is arranged in the blind hole 21. The elastic member 23 can be a spring. One end of the limiting rod 23 abuts against the elastic member 23, and the other end of the limiting rod 23 is inserted into the limiting groove 17.

[0059] The elastic element 23 is always in a compressed state, exerting an outward elastic force on the limiting rod 22, causing the outer end of the limiting rod 22 to be inserted into the limiting groove 17, thereby connecting the insulation plate 20 with the refrigerator body 10 and fixing the insulation plate 20 stably.

[0060] In some embodiments, to facilitate the installation and disassembly of the insulation plate 20, the lower surface of the insulation plate 20 is provided with a groove 24 communicating with the blind hole 21. The movement direction of the groove 24 is parallel to the extension direction of the limiting rod 23. A slider 25 is slidably connected in the groove 24. The slider 25 can be a rectangular connecting block. One end of the slider 25 is connected to the limiting rod 23, and the other end of the slider 25 extends out of the groove 24.

[0061] In some embodiments, the other end of the slider 25 is connected to an operating member 26, the lower surface of which is curved.

[0062] The operating component 26 can be a push plate. The lower surface of the operating component 26 is curved, which facilitates operation. When in use, the operating component 26 can be pushed to move left and right, which in turn drives the limiting rod 23 to slide left and right through the slider 25, and insert or separate it from the limiting groove 17, thus facilitating the installation or removal of the insulation plate 20.
