Detailed implementation manners

[0045] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present invention.

[0046] Embodiment 1:

[0047] A multifunctional refrigerator drawer includes a main drawer 1 and more than one sub - drawer 2. Among them, more than one insertion opening is provided on the drawer door of the main drawer 1, and the sub - drawer 2 is inserted into the main drawer 1 through the insertion opening, and at least one sub - drawer 2 is used to form a living fresh - keeping drawer.

[0048] Regarding the structures of the sub - drawer 2 and the main drawer 1, the sub - drawer 2 can be pulled out alone to take the food ingredients in the sub - drawer 2, avoiding excessive loss of cold air caused by pulling out the main drawer 1. When the main drawer 1 is opened, the sub - drawer 2 can also be taken out.

[0049] When the number of sub - drawers 2 is one, food ingredients can be placed in both the sub - drawer 2 and the main drawer 1. The functions of the sub - drawer 2 and the main drawer 1 are different. By adding structures such as ventilation, oxygen supply, and temperature adjustment to the sub - drawer 2, a living fresh - keeping drawer can be formed, which can provide a suitable living environment for live aquatic products, extend their survival time, and maintain the freshness of the aquatic products.

[0050] When the number of sub-drawers 2 is more than two, the main function of the main drawer 1 is to accommodate the sub-drawers 2. The food ingredients are placed in the corresponding sub-drawers 2 respectively. When taking the food ingredients, just pull out the corresponding sub-drawer 2. The functions of the two sub-drawers 2 are the same. Of course, it is preferred that the functions of the two sub-drawers 2 are different to store different food ingredients. For example, when there are two sub-drawers 2, ventilation and oxygen supply, temperature adjustment and other structures are added to one of the sub-drawers 2 to form a live fresh-keeping drawer, while the other sub-drawer 2 is an ordinary drawer; or, one of the sub-drawers 2 is a live fresh-keeping drawer and the other is a modified atmosphere fresh-keeping drawer (just add a modified atmosphere film to the drawer).

[0051] In addition, it is preferred that the outer surface of the drawer door of the sub-drawer 2 is on the same plane as the outer surface of the drawer door of the main drawer 1. To facilitate pulling out the sub-drawer 2, a drawer handle 201 is provided on the sub-drawer 2.

[0052] A middle partition can be provided in the main drawer 1 to separate the spaces for placing different sub-drawers 2.

[0053] Embodiment 2:

[0054] The present invention provides a multi-functional refrigerator drawer, including a main drawer 1 and more than one sub-drawer 2. Among them, more than one insertion port is provided on the drawer door of the main drawer 1, and the sub-drawer 2 is inserted into the main drawer 1 through the insertion port, and at least one sub-drawer 2 is used to form a live fresh-keeping drawer.

[0055] In order to enable the live fresh-keeping drawer to extend the survival time of live aquatic products and ensure that there is enough oxygen in the fresh-keeping drawer for the fresh food to survive, a gas diversion device 3 for driving the air flow circulation between the inside of the live fresh-keeping drawer and the outside of the refrigerator is provided on the live fresh-keeping drawer. The air outside the refrigerator can be introduced into the live fresh-keeping drawer to increase the oxygen content in the live fresh-keeping drawer.

[0056] Regarding the structure of the gas diversion device 3, specifically as follows: The gas diversion device 3 includes a telescopic tube 301 and an air pump 302. The air pump 302 is connected to the telescopic tube 301. The telescopic tube 301 passes through the main drawer 1 to connect the refrigerator wall and the live fresh-keeping drawer to communicate the inside of the live fresh-keeping drawer and the outside of the refrigerator. See Figure 2 , which shows that the telescopic tube 301 is connected to the rear side of the live fresh-keeping drawer. Since the length of the telescopic tube 301 can be changed, the telescopic tube 301 extends when the live fresh-keeping drawer is pulled out. Figure 2 shows that the live fresh-keeping drawer and the main drawer are pulled out together, and the telescopic tube 301 is in an extended state.

[0057] The air pump 302 can be arranged at the back of the outside of the refrigerator. Of course, the air pump 302 can also be arranged inside the live fresh-keeping drawer. At this time, a protective cover 303 needs to be arranged outside the air pump 302, and ventilation holes are arranged on the protective cover 303. SeeFigure 2 , which shows the air pump 302 arranged in the fresh-keeping drawer for living bodies. Refer to Figure 6 , which shows that the top opening of the protective cover 303 forms a ventilation hole. When the air pump 302 operates, the air outside the refrigerator can be drawn into the protective cover 303 and flow into the fresh-keeping drawer for living bodies through the top of the protective cover 303. Here, it should be noted that a certain amount of water is usually placed in the fresh-keeping drawer for living bodies. In order to ensure the normal operation of the air pump 302, the water level in the fresh-keeping drawer for living bodies should not exceed the height of the protective cover 303.

[0058] Regarding the connection and cooperation relationship between the telescopic tube 301, the main drawer 1, the refrigerator wall, and the fresh-keeping drawer for living bodies, it can be specifically as follows: Sealing sleeves 304 are arranged on the refrigerator wall and the fresh-keeping drawer for living bodies. Both ends of the telescopic tube 301 are fixed on the sealing sleeves 304 and are in sealed cooperation with the two sealing sleeves 304; the telescopic tube 301 is movably connected to the main drawer 1. Refer to Figure 2 , which shows that sealing sleeves 304 are arranged on the refrigerator wall and the fresh-keeping drawer for living bodies, and both ends of the telescopic tube extend into the corresponding sealing sleeves 304 and are fixedly connected to the sealing sleeves 304. By arranging the sealing sleeve 304 on the refrigerator wall (the refrigerator wall is in sealed cooperation with the sealing sleeve 304) and arranging the telescopic tube 301 in sealed cooperation with the sealing sleeve 304, the leakage of cold air in the refrigerator compartment can be prevented.

[0059] The telescopic tube 301 passes through the connection hole of the main drawer 1 and the diameter of the connection hole is larger than the diameter of the telescopic tube 301, so that the telescopic tube 301 is movably connected to the main drawer 1, which is convenient for pulling out the main drawer 1 and pulling out the fresh-keeping drawer for living bodies separately.

[0060] Preferably, the gas diversion device 3 further includes a pressure sensor for detecting the internal pressure of the fresh-keeping drawer for living bodies, and the pressure sensor is connected to the control device of the refrigerator. A three-way pipe can be set, with one end of the three-way pipe connected to the telescopic tube 301, one end connected to the air pump 302, and the other end installed with the pressure sensor. In addition, a one-way valve is preferably arranged on one side of the air outlet of the air pump 302.

[0061] Regarding the temperature adjustment in the living fresh-keeping drawer, the specific description is as follows: The multi-functional refrigerator drawer further includes a cover plate structure 4, at least the living fresh-keeping drawer is covered with the cover plate structure 4. The cover plate structure 4 includes a movable plate 401. Changing the position of the movable plate 401 can adjust the size of the area in the sub-drawer 2 communicating with the main drawer 1. For different aquatic organisms, their requirements for the living environment are different, especially the water temperature. When the area in the living fresh-keeping drawer communicating with the main drawer 1 is large, the amount of cold entering the living fresh-keeping drawer increases, which is beneficial to reducing the water temperature. When the area in the living fresh-keeping drawer communicating with the main drawer 1 is small, the amount of cold entering the living fresh-keeping drawer decreases, which is beneficial to raising the water temperature. In addition, when the multi-functional refrigerator drawer includes two sub-drawers 2, one of which is a living fresh-keeping drawer and the other is an ordinary drawer, as an ordinary drawer, the cover plate structure 4 can be provided therein, or the cover plate structure 4 can not be provided.

[0062] Regarding the specific structure of the cover plate structure 4, see Figure 7 , the cover plate structure 4 further includes an upper cover plate 402 and a support plate 403. The support plate 403 is arranged below the upper cover plate 402 and the two are fixedly connected. An installation space for the movable plate is formed between the support plate 403 and the upper cover plate 402. The movable plate 401 is inserted into the installation space for the movable plate and the movable plate 401 is in contact with the support plate 403 and the upper cover plate 402. A plurality of ventilation holes 404 are distributed on the upper cover plate 402. A linear driving device is arranged on the side of the support plate 403 facing away from the upper cover plate 402, and the telescopic shaft of the linear driving device is connected to the movable plate 401. The linear driving device is preferably a micro electric rod 15. See Figure 7 , when the telescopic shaft of the micro electric rod 15 moves in the extending direction, it drives the movable plate 401 to move in the direction of extending out of the installation space for the movable plate, gradually increasing the number of ventilation holes 404 on the upper cover plate 402 blocked; when the telescopic shaft of the micro electric rod 15 moves in the retracting direction, it drives the movable plate 401 to move in the direction of retracting into the installation space for the movable plate, reducing the number of ventilation holes 404 on the upper cover plate 402 blocked. In addition, it should be noted that when the movable plate 401 extends out and completely blocks the ventilation holes 404 on the support plate 403 that are not directly opposite, at this time, a part of the movable plate 401 is still located in the installation space for the movable plate, and since the movable plate 401 is in sealed cooperation with the installation space for the movable plate, the ventilation holes 404 on the upper cover plate 402 directly opposite the support plate 403 cannot be conducted either.

[0063] Regarding the connection between the movable plate 401 and the micro electric rod 15, a protruding part is arranged on the movable plate 401, and an insertion hole is arranged on the protruding part. The free end of the telescopic shaft of the micro electric rod 15 is inserted into the insertion hole on the protruding part.

[0064] Regarding the installation of the cover plate structure 4 on the living fresh-keeping drawer, claw-like projections 405 are arranged on the opposite sides of the cover plate structure 4, and clamping grooves are arranged on the inner side surfaces of the sub-drawer 2 or the main drawer 1. The claw-like projections 405 extend into the corresponding clamping grooves. SeeFigure 7 , showing the claws 405 on opposite sides of the cover plate structure 4. The claws 405 are L-shaped. Refer to Figure 2 and Figure 3 , preferably, slots are provided on the two inner side surfaces in front of and behind the main drawer 1, and the slots extend to the upper end surface of the main drawer 1. The L-shaped claws 405 extend into the slots and are supported on the slot surfaces of the slots.

[0065] A temperature sensor 14 is arranged inside the living body fresh-keeping drawer. The temperature sensor 14 is connected to the control device of the refrigerator. The temperature sensor 14 is used to detect the water temperature inside the living body fresh-keeping drawer, so as to adjust the water temperature inside the living body fresh-keeping drawer to adapt to the survival of aquatic organisms.

[0066] Preferably, heating plates 16 are arranged on the inner side surfaces of the living body fresh-keeping drawer. Grooves are arranged on the inner side walls of the living body fresh-keeping drawer, and the heating plates 16 are installed in the grooves.

[0067] When aquatic organisms are placed inside the drawer, the refrigerator can automatically identify the types of organisms and give their optimal living water temperatures. Refer to Figure 8 , the temperature sensor 14 detects whether the temperature inside the living body fresh-keeping drawer is equal to the required value. If the temperature inside the area is higher than the survival temperature of the organisms, a signal is fed back to the control device. The control device adjusts the operation of the micro electric cylinder on the cover plate structure 4, so that the micro electric cylinder rod retracts to the limit position, and the movable plate 401 also moves to the limit position accordingly. At this time, cold air is delivered to the inside of the living body fresh-keeping drawer through the circular air vents 404, so that the temperature inside the living body fresh-keeping drawer is appropriately reduced. At this time, the temperature sensor 14 monitors the temperature inside the area in real time. When the temperature is equal to the required value, the micro electric cylinder on the cover plate structure 4 resets (closes the air vents 404), and at the same time, the air pump 302 also stops operating.

[0068] When the temperature sensor 14 detects that the temperature inside the living body fresh-keeping drawer is lower than the survival temperature of the organisms, a signal is fed back to the control device. On the one hand, the control device drives the micro electric cylinder on the cover plate structure 4 to reset, extends the movable plate 401 to the limit position, and blocks the circular air vents 404, so that the inside of the living body fresh-keeping drawer is not communicated with the main drawer 1. On the other hand, the control device can adjust the operation of the heating plate 16 according to the actual situation, so that the temperature inside the living body fresh-keeping drawer rises slowly and meets the survival requirements of the organisms. Until the temperature inside the living body fresh-keeping drawer is equal to the required value, the control device stops the heating plate 16 from working, and at the same time, the air pump 302 also stops operating.

[0069] Preferably, a drain hole is provided at the bottom of the fresh-keeping drawer for living organisms, and a detachable sealing plug 6 is provided on the drain hole. The inner side surface of the bottom of the fresh-keeping drawer for living organisms slopes downward gradually in the direction from the back to the front, and the drain hole is located at a position close to the front side of the fresh-keeping drawer for living organisms. Since the survival time of aquatic organisms in the area is limited and the water quality requirements are relatively high, it is necessary to change the water frequently. For the convenience of users, when designing, the inner bottom of the drawer is designed to be inclined, and the height is lower closer to the drawer handle. When draining water, the user only needs to pull out the fresh-keeping drawer for living organisms and pull out the sealing plug 6. After the drainage is completed, the drain hole can be blocked by using the sealing plug 6, and water can be added to the corresponding area, which is convenient and fast.

[0070] As an optional implementation manner, a visual sensor is provided in the sub-drawer 2, and the visual sensor is connected to the control device of the refrigerator. The state in the fresh-keeping drawer for living organisms can be monitored in real time and displayed on the display screen of the refrigerator, providing convenience for users.

[0071] Embodiment 3:

[0072] Different from Embodiment 2, the multi-functional refrigerator drawer further includes a longitudinal partition structure 5. At least a longitudinal partition structure 5 is provided in the fresh-keeping drawer for living organisms. The longitudinal partition structure 5 is used to divide the sub-drawer 2 into two or more placement spaces. Different food ingredients can be placed in the placement spaces. For example, when the longitudinal partition structure 5 divides the fresh-keeping drawer for living organisms into two placement spaces, the two placement spaces are respectively used to place different aquatic organisms.

[0073] Specifically, when the multi-functional refrigerator drawer includes two sub-drawers 2, one of which is a fresh-keeping drawer for living organisms and the other is a common drawer, as a common drawer, a partition structure can be provided therein or not. When a partition structure is provided in the common drawer, only one board is required for the partition structure therein.

[0074] The longitudinal partition structure 5 is one and divides the sub-drawer 2 into two front and rear placement spaces; or the longitudinal partition structure 5 is two and is arranged in parallel at intervals in sequence along the front-to-back direction of the sub-drawer 2. See Figure 4 , which shows that the longitudinal partition structure 5 is one and divides the fresh-keeping drawer for living organisms into two front and rear placement spaces. Considering the size of the fresh-keeping drawer for living organisms, if it is divided into three or more placement spaces, the size of each placement space may be relatively small. Therefore, it is preferred to divide the fresh-keeping drawer for living organisms into two front and rear placement spaces. Of course, the longitudinal partition structure 5 can also be arranged to extend along the front-to-back direction of the fresh-keeping drawer for living organisms, dividing the fresh-keeping drawer for living organisms into two left and right placement spaces.

[0075] Regarding the positional relationship between the longitudinal partition structure 5 and the cover structure 4, there is a gap between the top surface of the longitudinal partition structure 5 and the cover structure 4. In this case, the placement spaces arranged in sequence in the front-rear direction of the fresh-keeping drawer for living bodies are connected, and the air flow replenished from outside the refrigerator flows in each placement space.

[0076] Alternatively, the top surface of the longitudinal partition structure 5 is in contact with the cover structure 4. However, at this time, a movable plate 501 is provided on the longitudinal partition structure 5, and changing the position of the movable plate 501 can adjust the size of the communication area between two adjacent placement spaces. Refer to Figure 2 , since the air pump 302 is located in the placement space near the rear side of the fresh-keeping drawer for living bodies, when the oxygen content in the placement space near the front side of the fresh-keeping drawer for living bodies is low, it is necessary to connect the placement spaces on both sides of the longitudinal partition structure 5. At this time, the position of the movable plate 501 can be adjusted to adjust the size of the communication area between two adjacent placement spaces.

[0077] Regarding the longitudinal partition structure 5, the specific structure can be as follows: Ventilation grooves, movable plate grooves, and installation grooves that are connected in sequence are formed on the top surface of the longitudinal partition structure 5. The movable plate 501 is located in the movable plate groove, and the driving device connected to the movable plate 501 is located in the installation groove. Flow holes 502 are distributed on the plate surfaces on both sides of the ventilation grooves. Refer to Figure 5 , which is a partial cross-sectional view of the longitudinal partition structure 5, showing the flow holes and the movable plate 501. The driving device connected to the movable plate 501 is preferably a micro electric rod 15. When the telescopic shaft of the micro electric rod 15 extends, it can push the movable plate 501 to move towards the ventilation groove. When the movable plate 501 moves to the extreme position, it can completely block the flow holes 502 on both sides of the ventilation groove. When the telescopic shaft of the micro electric rod 15 retracts to the reset position, the flow holes 502 on both sides of the ventilation groove are connected to the ventilation groove, and further, the placement spaces on both sides of the longitudinal partition structure 5 are connected.

[0078] Regarding the connection between the movable plate 501 and the micro electric rod 15, a U-shaped groove can be added to the movable plate 501, and the free end of the telescopic shaft of the micro electric rod 15 is stuck in the U-shaped groove.

[0079] Regarding the installation of the longitudinal partition structure 5 on the sub-drawer 2, the structure is as follows: T-shaped grooves are provided on the two opposite inner side surfaces of the sub-drawer 2, and T-shaped insert structures 503 are respectively formed at the left and right ends of the longitudinal partition structure 5, and the T-shaped insert structures 503 are inserted into the T-shaped grooves. Refer to Figure 6 , showing the T-shaped insert structures 503 at the left and right ends of the longitudinal partition structure 5. By pulling up the longitudinal partition structure 5, the longitudinal partition structure 5 can be detached from the sub-drawer 2, which is convenient for the installation and disassembly of the longitudinal partition structure 5.
