Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a refrigerator drawer and a refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device used to store fresh vegetables, fruits, meat products, and dairy products. The compressor and other components are typically located on one side of the lower part of the refrigerator, while the storage compartment is located on the other side, containing multiple refrigeration / freezing drawers. When you need to pull out a refrigeration / freezing drawer to place or retrieve food, the space inside is limited, and the area for opening and retrieving food is also narrow. To better place or retrieve food, the drawer needs to be pulled out a greater distance. However, this can easily cause the drawer to detach from the refrigerator and fall to the ground. Therefore, when pulling out a refrigeration / freezing drawer, you should use one hand or other tools to support the bottom of the drawer to prevent it from detaching or falling.

[0003] Therefore, in order to solve the above problems, some manufacturers have made the front cover of the refrigerator / freezer drawer movable and installed in the back box. When the user needs to put or take out food in the refrigerator / freezer drawer, he or she first pulls the refrigerator / freezer drawer out halfway (that is, the refrigerator / freezer drawer is in a half-open state), and then moves the front cover so that the front cover opens relative to the back box, thereby expanding the space in the refrigerator / freezer drawer to put or take out food. This makes it easier to put or take out food in the refrigerator / freezer drawer.

[0004] However, because refrigerators have components such as the compressor located at the bottom, the space inside the refrigerator / freezer drawers at the very bottom is smaller. As a result, the space to open and retrieve food is also narrower. Once the refrigerator / freezer drawer is pulled out halfway and the front cover is opened relative to the back, the refrigerator / freezer drawer is more likely to tilt and slide due to instability, which may cause it to touch the ground. This not only creates related hygiene problems but also reduces the user experience. Utility Model Content

[0055] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0056] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0057] The refrigerator drawer proposed in this utility model is illustrated by taking the refrigerator drawer located at the bottom of the refrigerator as an example. The refrigerator drawer can be either a refrigerator drawer or a freezer drawer, as described throughout the text.

[0058] In one embodiment, refer to Appendix Figure 1This utility model proposes a refrigerator drawer, including a drawer back box 10, wherein the drawer back box 10 has an opening on one side along the pull-out direction of the refrigerator drawer, and the drawer front cover 20 is matched and movably installed in the opening. It also includes a horizontal moving mechanism 30, a vertical moving mechanism 40 and a support plate 50.

[0059] The moving end of the lateral moving mechanism 30 is connected to the longitudinal moving mechanism 40, and the moving end of the longitudinal moving mechanism 40 is connected to the support plate 50, and the support plate 50 is located below the drawer back box 10.

[0060] The horizontal moving mechanism 30 can drive the vertical moving mechanism 40 and the support plate 50 to move horizontally along the pull-out direction of the refrigerator drawer. The vertical moving mechanism 40 can drive the support plate 50 to rise and connect with the bottom of the drawer back box 10 so that the refrigerator drawer is in the pull-out state.

[0061] The refrigerator drawer proposed in this utility model also includes a control unit, which is electrically connected to the horizontal moving mechanism 30 and the vertical moving mechanism 40.

[0062] When a user needs to pull out the refrigerator drawer located at the bottom of the refrigerator, the control unit will control the lateral movement mechanism 30 to drive the longitudinal movement mechanism 40 and the support plate 50 to move along the direction of pulling out the refrigerator drawer. When the movement distance reaches the set distance, the control unit will then control the longitudinal movement mechanism 40 to raise the support plate 50 to connect the support plate 50 to the bottom of the drawer back box 10. Then the control unit will control the lateral movement mechanism 30 to continue moving along the direction of pulling out. At this time, the lateral movement mechanism 30 will drive the longitudinal movement mechanism 40, the support plate 50 and the drawer back box 10 connected to the support plate 50 to move together until the lateral movement mechanism 30 reaches its maximum movement distance. At this time, the refrigerator drawer is in the fully pulled-out state.

[0063] Then, open the front cover 20 of the drawer relative to the back cover 10 of the drawer to open the refrigerator drawer, thereby expanding the space in the refrigerator drawer for placing or retrieving food, making it easier to place or retrieve food in the refrigerator drawer.

[0064] Therefore, compared to the existing technology of directly pulling out the refrigerator drawer and then opening the front cover of the refrigerator drawer relative to the back box of the refrigerator drawer, this utility model controls the support plate 50 to be connected to the bottom of the drawer back box 10 through the horizontal moving mechanism 30 and the vertical moving mechanism 40. When the refrigerator drawer is pulled out and the front cover 20 of the drawer is opened relative to the back box 10 of the drawer, the support plate 50 will support the refrigerator drawer. This can improve the stability of the refrigerator drawer when it is pulled out and opened, reduce the occurrence of the refrigerator drawer tilting and slipping due to the unstable center of gravity when it is pulled out and opened, prevent the refrigerator drawer from touching the ground or table when it is pulled out and opened, prevent hygiene problems of the refrigerator drawer, and also improve the user experience.

[0065] The main hygiene issues with refrigerator drawers are:

[0066] When refrigerator drawers touch the floor or countertop, they easily pick up contaminants from these surfaces, including dust, bacteria, mold, and other microorganisms. Once a refrigerator drawer is contaminated, these contaminants can spread through the drawer's contact surfaces to other food items inside the refrigerator, causing cross-contamination and increasing the risk of food poisoning and other food safety issues.

[0067] Specifically, refer to the appendix Figure 1 and 7 The lateral movement mechanism 30 includes a lateral motor 301 and at least one lateral telescopic rod 302; the lateral motor 301 is located in the refrigerator body 90 below the freezer drawer; the control unit is electrically connected to the lateral motor 301.

[0068] One end of each of the horizontal telescopic rods 302 is connected to the moving end of the horizontal motor 301, and the other end of each of the horizontal telescopic rods 302 and the side facing the bottom of the drawer back box 10 are provided with a longitudinal moving mechanism 40.

[0069] When a user needs to pull out the refrigerator drawer located at the bottom of the refrigerator, the control unit will activate the horizontal motor 301. The horizontal motor 301 will then drive the horizontal telescopic rod 302 to extend along the direction of pulling out the refrigerator drawer, thereby driving the longitudinal moving mechanism 40 and the support plate 50 located on the horizontal telescopic rod 302 to move together.

[0070] In this embodiment, the number of transverse telescopic rods 302 is preferably two, and the two transverse telescopic rods 302 are arranged in parallel. Of course, the number of transverse telescopic rods 302 can also be three or more, which is not limited here.

[0071] Specifically, refer to the appendix Figure 1 and 7 The longitudinal moving mechanism 40 includes a longitudinal motor 401 and a longitudinal telescopic rod 402; the control unit is electrically connected to the longitudinal motor 401.

[0072] Each of the horizontal telescopic rods 302 has a vertical motor 401 at its other end and on the side facing the bottom of the drawer rear compartment 10. The moving end of each vertical motor 401 is connected to one end of the vertical telescopic rod 402, and the other end of each vertical telescopic rod 402 is connected to the bottom of the support plate 50.

[0073] When the control unit controls the horizontal telescopic rod 302 to extend a preset distance (preferably half the distance of the horizontal telescopic rod 302) along the pull-out direction of the refrigerator drawer via the horizontal motor 301, the control unit then starts the vertical motor 401. The vertical motor 401 will then drive the vertical telescopic rod 402 to extend towards the bottom of the drawer back box 10 until the support plate 50 on the vertical telescopic rod 402 is connected to the bottom of the drawer back box 10. At this point, the vertical motor 401 stops starting, and the control unit then starts the horizontal motor 301 again, so that the horizontal telescopic rod 302 is fully extended along the pull-out direction of the refrigerator drawer. When it extends, the horizontal telescopic rod 302 will also drive the vertical moving mechanism 40, the support plate 50, and the drawer back box 10 connected to the support plate 50 to move together.

[0074] Specifically, refer to the appendix Figure 7 The top of the support plate 50 is also provided with a slot 501, and the bottom of the drawer back box 10 is provided with a buckle (not shown, same throughout the text) corresponding to the slot 501.

[0075] When the support plate 50 is connected to the bottom of the drawer back box 10, the buckle and the slot 501 can be matched and engaged. In this way, the drawer back box 10 can be pulled outward together with the support plate 50 by the horizontal telescopic rod 302, realizing the automatic opening of the refrigerator drawer.

[0076] Among them, refer to the appendix Figure 7 The slot 501 is equipped with a pressure sensor 80. When the buckle is matched and engaged with the slot 501, the buckle can contact the pressure sensor 80. The control unit is electrically connected to the pressure sensor 80.

[0077] In this way, when the pulled-out refrigerator drawer needs to be pushed back into the refrigerator, the user first disengages the latch of the drawer back box 10 from the slot 501. This greatly reduces the pressure value measured by the pressure sensor 80. At this time, the pressure sensor 80 sends a third shut-off electrical signal to the control unit. After receiving the signal, the control unit controls the horizontal telescopic rod 302 to retract along the direction of pushing back the refrigerator drawer via the horizontal motor 301. After the horizontal telescopic rod 302 drives the drawer back box 10 to retract into the refrigerator body 90, the control unit then controls the vertical telescopic rod 402 to retract via the vertical motor 401, so that the support plate 50 no longer supports the drawer back box 10. At this time, the automatic push-back of the pulled-out refrigerator drawer can be completed.

[0078] In order to detect the extension distance of the lateral telescopic rod 302 in real time and facilitate the starting of the longitudinal motor 401, the control unit refers to the attached document. Figure 1 The lateral motor 301 has a first infrared sensor 60 on the side facing the lateral telescopic rod 302. The first infrared sensor 60 is used to detect the extension distance of the lateral telescopic rod 302. The control unit is electrically connected to the first infrared sensor 60. The distance detected by the first infrared sensor 60 is the distance between the first infrared sensor 60 and the longitudinal telescopic rod 402.

[0079] In order to detect the extension distance of the longitudinal telescopic rod 402 in real time, the control unit refers to the attached... Figure 1 and 7 A second infrared sensor 70 is provided on the side of the longitudinal motor 401 facing the support plate 50. The second infrared sensor 70 is used to detect the extension distance of the longitudinal telescopic rod 402. The control unit is electrically connected to the second infrared sensor 70. The distance detected by the second infrared sensor 70 is the distance between the second infrared sensor 70 and the support plate 50.

[0080] Among them, refer to the appendix Figure 2 and 4 The bottom of the drawer back box 10 facing the drawer front cover 20 is provided with a pivot 103. The pivot 103 is hinged to the bottom of the drawer front cover 20, so that the drawer front cover 20 can be opened or closed relative to the drawer back box 10.

[0081] Both ends of the drawer front cover 20 facing the opening of the drawer back box 10 have movable plates 201 extending outward. The drawer back box 10 includes two side walls 101 perpendicular to the pull-out direction. Each side wall 101 has a matching movable space corresponding to the movable plate 201. The movable plate 201 can slide within the movable space.

[0082] In this way, when the front cover 20 of the drawer is opened relative to the back cover 10 of the drawer to expand the space for placing or retrieving food in the refrigerator drawer, the food inside the refrigerator drawer will be blocked by the movable plate 201 and will not fall out of the opening gap, and the movable plate 201 is not easily damaged.

[0083] To prevent the drawer front cover 20 from being fully opened relative to the drawer back box 10, causing the drawer front cover 20 to rotate to the bottom of the drawer back box 10, please refer to the attached document. Figure 2-5 Each movable plate 201 has an abutment portion 202 on the side away from the front cover of the drawer 20. The abutment portion 202 can abut against the top of the movable space so that the front cover of the drawer 20 is in an open state relative to the back box of the drawer 10.

[0084] To prevent the drawer front cover 20 from failing to connect tightly with the drawer back cover 10 when the drawer front cover 20 is closed relative to the drawer back cover 10, please refer to the attached document. Figure 6 The drawer front cover 20 has an abutment groove 203 extending outward from the top of the drawer front cover 20 and the side facing the opening of the drawer rear box 10; the abutment groove 203 is made of a magnetic material that can be attracted by the magnetic body 102, or the abutment groove 203 is provided with an adsorption block made of magnetic material corresponding to the magnetic body 102.

[0085] The top of the side wall 101 and the side near the front cover of the drawer 20 are provided with magnetic bodies 102; the magnetic bodies 102 are preferably neodymium iron boron magnets.

[0086] The abutment groove 203 can be magnetically attracted to the corresponding magnetic body 102, so that the front cover of the drawer 20 is in a closed state relative to the back box of the drawer 10.

[0087] In one embodiment, the present invention also provides a refrigerator including the refrigerator drawer described above, wherein the refrigerator drawer is located at the bottom layer of the refrigerator.

[0088] In order to pull the drawer back box 10 out a specified distance relative to the refrigerator, the control unit will automatically control the horizontal movement mechanism 30 and the vertical movement mechanism 40 to support and move the drawer back box 10, as shown in the attached figure. Figure 1 The refrigerator includes a refrigerator body 90, and the refrigerator body 90 is provided with a slide rail 91 corresponding to the refrigerator drawer. The slide rail 91 is also provided with a spring locking mechanism 92. The bottom of the drawer back box 10 is slidably connected to the slide rail 91, and the spring locking mechanism 92 can contact the bottom of the drawer back box 10.

[0089] When the refrigerator drawer is pulled outward, the bottom of the drawer back box 10 disengages from the spring locking mechanism 92, and the spring inside the spring locking mechanism 92 is released. When the refrigerator drawer is pushed back inward, as the refrigerator drawer gradually retracts inward, the spring inside the spring locking mechanism 92 is continuously compressed until the spring locking mechanism 92 re-contacts the bottom of the drawer back box 10, at which point the spring inside the spring locking mechanism 92 is compressed to allow the refrigerator drawer to be pulled out again.

[0090] Therefore, the refrigerator drawer proposed in this utility model can improve the level of automation by triggering the spring locking mechanism 92, thereby enhancing the user experience. When the spring locking mechanism 92 is triggered and in a released state, the control unit will sequentially control the horizontal motor 301 and the vertical motor 401 to perform corresponding movements, so that the support plate 50 supports the drawer back box 10.

[0091] The spring locking mechanism 92 is electrically connected to the control unit. The structure of the spring locking mechanism 92, which is in the corresponding release state and compression state according to whether the refrigerator drawer is pulled out or pushed back, is existing technology and will not be described in detail here.

[0092] The usage process of this utility model:

[0093] When a user needs to pull out the refrigerator drawer located at the bottom of the refrigerator, the drawer will stop pulling when it is pulled outward and disengaged from the spring locking mechanism 92. The spring locking mechanism 92 will be in the released state and send an open electrical signal to the control unit. At this time, the control unit will drive the horizontal telescopic rod 302 to extend along the direction of pulling out the refrigerator drawer via the horizontal motor 301. When the first infrared sensor 60 detects that the horizontal telescopic rod 302 has extended a first preset distance, the first infrared sensor 60 will send a first start electrical signal to the control unit. After receiving the signal, the control unit will temporarily turn off the horizontal motor 301 and start the vertical motor 401, so that the vertical motor 401 drives the support plate 50 to move along the bottom of the drawer back box 10 via the vertical telescopic rod 402.

[0094] When the longitudinal telescopic rod 402 is fully extended, the latch at the bottom of the drawer back box 10 engages with the slot 501 of the support plate 50. That is, after the second infrared sensor 70 detects that the longitudinal telescopic rod 402 has extended a second preset distance (fully extended), the second infrared sensor 70 sends a first shut-off electrical signal to the control unit. Upon receiving this signal, the control unit shuts off the longitudinal motor 401. Then, the pressure measured by the pressure sensor 80 in the slot 501 reaches a preset pressure threshold. At this point, the pressure sensor 80 sends a second start electrical signal to the control unit. Upon receiving this signal, the control unit restarts the horizontal motor 301, thereby driving the longitudinal moving mechanism 40 located on the horizontal telescopic rod 302 and the support plate 50 to move together in the pull-out direction until the first infrared sensor 60 detects that the horizontal telescopic rod 302 has reached its maximum extension distance. At this point, the first infrared sensor 60 sends a second shut-off electrical signal to the control unit. Upon receiving this signal, the control unit shuts off the horizontal motor 301, and the refrigerator drawer completes the pull-out action.

[0095] The user then opens the front cover 20 of the drawer relative to the back cover 10 of the drawer, so that the abutment part 202 abuts against the top of the movable space, thereby expanding the space in the refrigerator drawer for placing or retrieving food.

[0096] When the user needs to push the refrigerator drawer back, first close the front cover 20 of the drawer relative to the back box 10 of the drawer so that the abutment groove 203 is magnetically attracted to the magnetic body 102. Then, the user first lifts the refrigerator drawer up so that the buckle disengages from the slot 501. When the refrigerator drawer is put down, the buckle will engage with the slot 501 again. However, when the refrigerator drawer is lifted upwards, the pressure measured by the pressure sensor 80 in the slot 501 will be less than the preset pressure threshold. At this time, the pressure sensor 80 will send a third shut-off electrical signal to the control unit. After receiving the signal, the control unit will start the horizontal motor 301, which will drive the vertical moving mechanism 40 on the horizontal telescopic rod 302, the support plate 50, and the refrigerator drawer connected to the support plate 50 to move together in the push-back direction until the refrigerator drawer is completely pushed back into the refrigerator body 90. That is, after the first infrared sensor 60 detects that the horizontal telescopic rod 302 has retracted by a third preset distance, the first infrared sensor 60 will send a fourth shut-off electrical signal to the control unit. After receiving the signal, the control unit will control the vertical telescopic rod 402 and the support plate 50 to retract completely. That is, after the second infrared sensor 70 detects that the vertical telescopic rod 402 has retracted by a second preset distance, the second infrared sensor 70 will send a fifth shut-off electrical signal to the control unit. After receiving the signal, the control unit will use the horizontal motor 301 to completely retract the horizontal telescopic rod 302. At this time, the refrigerator drawer completes the push-back action.
