Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator storage, in particular to a shelf device and a storage device. Background Art

[0002] At present, the space inside the refrigerator is divided by shelves. The shelves divide the space inside the box in height, which limits the placement of items in the compartment. Some items with too high height are restricted by the space divided by the shelves and cannot be placed on the shelves. If the shelf is removed to accommodate the too-high items, the accommodation limit of the box body is reduced. And if there are items with very low height and very high height on different layers at the same time, due to the fixed gap of the current shelves, the gap of the shelf for the items with low height is wasted, and the gap of the shelf for the items with high height is not enough. At this time, a shelf device with adjustable position is urgently needed to maximize the utilization of the box body space. Summary of the Utility Model

[0003] In order to solve the technical problem that the gap of the existing shelf is fixed and cannot be adjusted, the utility model provides a shelf device and a refrigerator.

[0004] The technical scheme adopted by the utility model is as follows:

[0005] The utility model provides a shelf device, comprising:

[0006] At least one guide rod, which is vertically arranged;

[0012] Further, a guide block is connected to the side surface of the shelf. The guide block is sleeved on the guide rod and can move up and down along the guide rod.

[0013] Further, the height of the top surface of the guiding block exceeds the height of the top surface of the shelf it is connected to, and the height of the bottom surface of the guiding block is lower than the height of the bottom surface of the shelf it is connected to.

[0014] Further, the driving assembly includes: a vertically arranged screw rod, nuts corresponding to the shelves one by one at different heights on the screw rod, and a motor connected to each shelf for driving the nut corresponding to the shelf to rotate. The motor drives the nut to rotate forward or backward to make the nut move upward or downward along the screw rod, thereby driving the motor and the shelf connected to the motor to move accordingly.

[0015] Further, an umbrella-shaped driven gear is fixedly sleeved on the outer peripheral surface of the nut, the transmission shaft of the motor is perpendicular to the screw rod, and an umbrella-shaped driving gear that cooperates with the umbrella-shaped driven gear is sleeved thereon.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present 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 only used to explain the present utility model and are not used to limit the present utility model.

[0036] The principle and structure of the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0037] Since the shelf gap in the current refrigerator is fixed, there is a waste of the shelf gap for items with a low height, and the shelf gap for items with a high height is insufficient. At this time, there is an urgent need for a shelf device with adjustable position to achieve the maximum utilization of the cabinet space.

[0038] Based on the above problems, as Figure 1 、 2As shown in the figure, the present utility model provides a shelf device that can maximize the utilization of the space of the shelf. The shelf device can be specifically applied to the compartment 5 of a refrigerator. Taking the setting in the refrigerator compartment 5 as an example, the shelf device includes: two guide rods 7, multiple shelves 1, a driving assembly, and a positioning sensor. The two guide rods 7 are vertically arranged in the refrigerator compartment 5 and are close to the back side of the compartment 5. The multiple shelves 1 are all connected to the guide rods 7 and are located at different heights of the guide rods 7. Specifically, the rear side of each shelf 1 is simultaneously connected to the same height of the two guide rods 7, so that the shelf 1 remains horizontal, and the shelf 1 can slide along the guide rod 7 to adjust the height of the shelf 1. The driving assembly is connected to each shelf 1 and can drive the shelf 1 to move up and down respectively to adjust the position. The positioning sensor is arranged at the bottom of each shelf 1 and is used to form an induction area 43 close to the bottom surface of the shelf 1. The positioning sensor senses whether there is an item 6 in the induction area 43 by emitting an induction signal.

[0039] The shelf of the present utility model can not only adjust the position, but also be adjusted according to the placed item 6 through infrared detection, accurately control the gap between the item 6 and the shelf 1, and solve the problem that the item 6 cannot be placed due to the position limitation of the shelf.

[0040] As Figures 3 to 5 shown, in a specific embodiment, the positioning sensor includes: a transmitter and a receiver. The transmitter and the receiver are respectively arranged at the two side edges of the bottom surface of the shelf 1, and the detection area between the transmitter and the receiver is the induction area 43. That is, it is equivalent to setting a layer of detection network on the bottom surface of the shelf 1. As long as an item 6 touches the detection network, the positioning sensor can sense it and emit a corresponding detection signal.

[0041] By directly setting the positioning sensor at the bottom of the shelf 1, it is simpler than the traditional distance detection method. When the space needs to be adjusted, directly adjust the height of the shelf 1 until the top of the item 6 placed on the lower layer touches the induction area 43, then stop adjusting the height of the shelf 1 downward.

[0042] Preferably, the positioning sensor is an infrared signal sensor, that is, the transmitter is an infrared transmitter 41 and the receiver is an infrared receiver 42. When the receiver can normally receive the infrared rays emitted by the transmitter, it means that there is no item 6 at the bottom of the shelf 1 at this time. When the receiver cannot fully receive (as Figure 5 shown) or there is an abnormal reception (as Figure 4 shown), it means that there is an item 6 at the bottom of the shelf 1 at this time. The detection method is simple and reliable, and does not require complex distance calculation.

[0043] In other embodiments, the positioning sensor can also be a sound wave sensor, which can also detect the item 6.

[0044] In a specific embodiment, a circular tubular guide block 2 is connected to the rear side of the shelf 1. The guide block 2 is sleeved on the guide rod 7 and can move up and down along the guide rod 7. That is, the shelf 1 is connected to the guide rod 7 through the guide block 2, enabling the shelf 1 to move up and down in the vertical height direction along the guide rod 7 to adjust the height.

[0045] Specifically, the height of the top surface of the guide block 2 exceeds the height of the top surface of the shelf 1 it is connected to, and the height of the bottom surface of the guide block 2 is lower than the height of the bottom surface of the shelf 1 it is connected to.

[0046] That is, when adjusting the height of the shelf 1, when there is no item 6 between two shelves 1, the shelf 1 can be adjusted to a position where its guide block 2 contacts the guide block 2 of the lower shelf 1, and the shelves 1 do not directly contact. This avoids the shelves 1 being squeezed and collided, and reserves a safety distance for the shelves 1.

[0047] Such as Figure 6 shown, in a specific embodiment, the driving assembly includes: a vertically arranged screw rod 31, a plurality of nuts 32 and a motor 33. The screw rod 31 is vertically arranged and can be specifically arranged near the guide rod 7; a plurality of nuts 32 are threadedly connected to the screw rod 31. When each nut 32 rotates forward, it will automatically move upward along the screw rod 31, and when it rotates backward, it will automatically move downward along the screw rod 31. Each nut 32 correspondingly connects or supports a corresponding shelf 1. The motor 33 is connected to the shelf 1 (or on the connecting piece guide block 2 of the shelf 1). Specifically, the housing of the motor 33 is fixedly connected to the shelf 1, and the rotating shaft of the motor 33 is rotatably connected to the nut 32. At the same time, the nut 32 provides a supporting force for the rotating shaft of the motor 33. The motor 33 drives the nut 32 to rotate forward or backward to make the nut 32 move upward or downward along the screw rod 31, thereby driving the motor 33 and the shelf 1 connected to the motor 33 to move accordingly.

[0048] Through the driving assembly, each shelf 1 can be independently driven to move up and down. At the same time, the structure is simple and reliable. Only the motor 33 needs to be driven to rotate forward and backward. All the nuts 32 used for driving share one screw rod 31, which simplifies the driving structure.

[0049] Specifically, an umbrella-shaped driven gear is fixedly sleeved on the outer peripheral surface of the nut 32, and the transmission shaft of the motor 33 is perpendicular to the screw rod 31 and is sleeved with an umbrella-shaped driving gear that cooperates with the umbrella-shaped driven gear.

[0050] By setting the mating form of the bevel gears, when the nut 32 does not rotate, the meshing surface of the bevel driven gear is inclined upward, and the meshing surface of the bevel driving gear on the transmission shaft of the motor 33 is inclined downward to cooperate with the meshing surface of the bevel driven gear. That is, the motor 33 as a whole is held by the nut 32, so that the shelf 1 fixedly connected to the housing of the motor 33 is maintained at the current height and will not automatically fall along the guide rod 7. At the same time, when the rotating shaft of the motor 33 drives the nut 32 to rotate through the bevel driving gear, the shelf 1 can also be driven to move up and down by the up and down movement of the nut 32 along the screw rod 31, and its connection structure is simple and reliable.

[0051] Specifically, the casing part of the motor 33 is fixedly connected to the shelf 1 or the guide block 2, so that the motor 33 and the shelf 1 rise and fall together, and arranging the motor 33 on the shelf 1 is convenient for the overall assembly and reduces the assembly difficulty.

[0052] The present utility model also proposes a storage device, including a shelf device thereon. The shelf 1 of the shelf device can not only adjust its position, but also be adjusted according to the infrared detection and the articles 6 placed, accurately controlling the gap between the articles 6 and the shelf 1, solving the problem that the articles 6 cannot be placed due to the position limitation of the shelf, and improving the space utilization rate of the storage device.

[0053] As Figure 7 shown, in a specific embodiment, the storage device is a refrigerator. The refrigerator includes a compartment 5, and the shelf device is directly installed in the compartment 5 of the refrigerator, which can flexibly utilize the storage space of the refrigerator compartment 5 and improve the space utilization rate of the refrigerator.

[0054] The present utility model realizes the stepless division of the internal space of the box body by using a refrigerator shelf with adjustable height, improves the space utilization rate inside the box body. Users can adjust the use situation of the shelves in the space according to their own usage habits, and use the space of the box body to the greatest extent. The shelf is automatically controlled and adjusted according to the infrared detection and the detection logic, which maximally improves the space utilization rate of the box body and facilitates the placement of articles.

[0055] The specific control logic of the shelf device is as follows:

[0056] The infrared emitter of the infrared sensor emits infrared light to the infrared receiver (the infrared light can form a mesh-shaped induction area on the bottom surface of the partition board);

[0057] Determine whether the infrared receiver normally receives the infrared signal,

[0058] If so, move the shelf down by 5 mm, and determine whether the guide block contacts another guide block. If it contacts, it means that the height of the article is relatively low. At this time, to avoid the shelf from colliding, stop moving the shelf. If it does not contact, return to the step of the infrared emitter of the infrared sensor emitting infrared light to the infrared receiver.

[0059] If not, pause the downward movement of the shelf, indicating that the item may be about to be touched by the lower part of the shelf, and repeat the step of the infrared emitter of the infrared sensor emitting infrared light to the infrared receiver multiple times. If it is determined that the infrared signal is not received normally, stop the downward movement of the shelf.
