Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, specifically to an adjustment structure, a refrigerator, and an adjustment method. Background Technology

[0002] After installing a new refrigerator or moving it, it's common for the refrigerator to become unstable or tilted. A tilted refrigerator can cause items inside to be placed unstably, and excessive tilting can even pose a safety hazard. The tilt usually occurs because some of the four corners of the bottom are higher than others. In this case, the lower corners need to be raised and supported to make all four corners the same height, thus leveling the refrigerator. This process is called refrigerator leveling. Most modern refrigerators have adjustable support feet at the four corners of the bottom. Adjusting these feet requires the user to bend down to adjust the refrigerator, which is strenuous and inconvenient. Furthermore, when the refrigerator is built-in and pushed into a cabinet, height adjustment becomes impossible.

[0003] Furthermore, refrigerators are one of the most common and indispensable appliances in modern households. They can store food for a long time, greatly reducing the rate of bacterial growth. However, as refrigerators have become larger, moving them has become extremely inconvenient. If the refrigerator needs to be repositioned, it requires two people to lift it, which is very troublesome, and there is a chance that the refrigerator will tip over. Especially with built-in refrigerators, once pushed into the cabinet, the gaps in all directions are very small, making it difficult to move and adjust the gaps.

[0004] Therefore, existing technologies need further development. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an adjustment structure, a refrigerator, and an adjustment method to solve the technical problem of instability of refrigerators during placement and movement in related technologies.

[0012] A refrigerator is provided, including the aforementioned adjustment structure. The adjustment structure is disposed at the bottom of the refrigerator, and the adjustment structure has at least two adjustment components, which are arranged at intervals on a straight line along the rotation axis of the adjustment seat.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] According to an embodiment of the present invention, an adjustment structure is provided; please refer to [link / reference]. Figures 1 to 6The adjustment structure includes an adjustment component 1, which has an adjustment seat 11 connected to the component 10 to be adjusted, and the adjustment seat 11 is movably arranged; a drive component connected to the adjustment component 1 to drive the adjustment seat 11 to rotate; a first pressure sensor 2 and a second pressure sensor 3, both located at the bottom of the component 10 to be adjusted, with the rotation axis of the adjustment seat 11 located between the first pressure sensor 2 and the second pressure sensor 3; and a control module 4, which is signal-connected to the first pressure sensor 2, the second pressure sensor 3, and the drive component. With the above arrangement, the pressure on both sides of the adjustment seat 11 is detected by the first pressure sensor 2 and the second pressure sensor 3. The pressure distribution of the component 10 to be adjusted is determined by the measured pressure. The movable adjustment seat 11 is used to adjust the center of gravity of the component 10 to be adjusted, thereby adjusting the pressure distribution at various parts of the bottom of the component 10, thus making the component 10 to be adjusted more stably moved or placed, solving the technical problem of unstable placement and movement of refrigerators in related technologies.

[0020] Specifically, in this embodiment, the adjustment seat 11 can move or rotate, or move in other ways. By moving the adjustment seat 11, the body of the component to be adjusted 10 can be rotated or moved, thereby adjusting the local pressure distribution.

[0021] In the adjustment structure of this embodiment, see Figure 2 , Figure 3 The adjustment assembly 1 includes a support wheel 12, which is rotatably connected to the adjustment seat 11. The support wheel 12 is rotatably disposed and is used to abut against the ground to form a rotation space 20 between the adjustment seat 11 and the ground. In this way, by setting the support wheel 12, the movement of the component 10 to be adjusted can be realized, and a fulcrum can be provided for the entire device to adjust the pressure of various parts of the adjustment component 10.

[0022] To implement the adjustment function, see [link / reference]. Figure 2 , Figure 3 In the adjustment structure of this embodiment, the adjustment seat 11 includes: a mounting plate 111, on which mounting holes 1111 are provided for connection with the component 10 to be adjusted; two support plates 113, which are connected to the mounting plate 111 at intervals, and each of the two support plates 113 is provided with a support hole 1131; and a support wheel 12 has a rotating shaft 121, which is rotatably inserted into the support hole 1131. Thus, the adjustment seat 11 can rotate relative to the support wheel 12, thereby achieving the adjustment purpose.

[0023] Specifically, the top of the adjusting seat 11 is provided with a connecting plane, and multiple mounting holes 1111 are provided on the connecting plane. The body of the component to be adjusted 10 is provided with a connector inserted into the mounting hole 1111, thereby connecting with the adjusting seat 11. In this way, when the adjusting seat 11 moves, it can also drive the component to be adjusted 10 to move.

[0024] See Figure 2 , Figure 3 In the adjustment structure of this embodiment, the driving component includes: a connecting seat 13, which is disposed between two support plates 113 and connected to both support plates 113; a gear portion 131 is provided on the connecting seat 13; and a worm gear 14, which is rotatably disposed and threadedly connected to the gear portion 131. Rotating the worm gear 14 drives the adjustment seat 11 to rotate. Thus, through the transmission via the worm gear 14 and the gear portion 131, a smooth adjustment function can be achieved.

[0025] In the adjustment structure of this embodiment, the drive assembly includes: a rotating part 15, which is rotatably connected to the adjustment seat 11, and a transmission gear 151 is provided on the rotating part 15; and a drive motor, on the output shaft of which a drive gear is provided, and the drive gear meshes with the transmission gear 151. This provides sufficient torque to the rotating part 15 for rotational movement.

[0026] Specifically, in the adjustment structure of this embodiment, there are multiple first pressure sensors 2, which are arranged at intervals and are all located on the side of the adjustment component 1 away from the second pressure sensor 3.

[0027] Specifically, there are multiple second pressure sensors 3, which are arranged at intervals and are all located on the side of the adjustment component 1 away from the first pressure sensor 2. In this way, by measuring the pressure at multiple points, the adjustment can be made more accurately.

[0028] The refrigerator of this embodiment includes the above-mentioned adjustment structure, which is located at the bottom of the refrigerator. The adjustment structure has at least two adjustment components 1, which are arranged at intervals on the straight line of the rotation axis of the adjustment seat 11. The first pressure sensor 2 and the second pressure sensor 3 are used to detect the pressure between the refrigerator body and the ground.

[0029] See Figure 6The adjustment method of this embodiment is used to adjust the refrigerator described above. The adjustment method includes: detecting the pressure value Tq of the first pressure sensor 2 of the adjustment structure; detecting the pressure value Th of the second pressure sensor 3 of the adjustment structure; and controlling the adjustment seat 11 of the adjustment structure to rotate according to the values ​​of Tq and Th. By using the above settings, the pressure on both sides of the bottom of the refrigerator is adjusted, thereby bringing the refrigerator to the desired state, thus facilitating the movement and placement of the refrigerator.

[0030] In the adjustment structure of this embodiment, the adjustment method includes: moving the refrigerator to the target position; comparing the values ​​of Tq and Th; if Tq is greater than Th, rotating the adjustment seat 11 along a first preset direction to decrease the value of Tq and increase the value of Th; if Tq is less than Th, rotating the adjustment seat 11 along a second preset direction to increase the value of Tq and decrease the value of Th. In this way, after moving and adjusting the refrigerator, the pressure on each part of the bottom of the refrigerator is evenly distributed, thereby achieving a stable placement of the refrigerator.

[0031] In some embodiments, the first preset direction is opposite to the second preset direction.

[0032] In the adjustment structure of this embodiment, the first pressure sensor 2 is set on the side of the rotation axis of the adjustment seat 11 close to the door 101 of the refrigerator, and the second pressure sensor 3 is set on the side of the rotation axis of the adjustment seat 11 away from the door 101. A threshold T0 is set; if Tq-Th≥T0, the refrigerator is pushed to the target position; if Tq-Th<T0, the adjustment seat 11 is controlled to rotate until Tq-Th≥T0. In this way, before moving the refrigerator, the front and rear pressures of the refrigerator are adjusted to increase the pressure at the front, so that the refrigerator will not tilt forward when pushed, which is beneficial to the movement of the refrigerator.

[0033] The movement and limiting of the refrigerator body in this embodiment are described as follows: Currently, the refrigerator market is mainly developing towards high-end and diversified products, with high-end, large-capacity, frost-free refrigerators becoming increasingly popular. Large-capacity refrigerators are quite heavy, making them difficult to move, let alone fine-tuning the position of a built-in refrigerator within a cabinet – the difficulty is considerable. This application utilizes a gear and worm gear to adjust the tilt angle of the adjustment seat fixed to the refrigerator, as well as the height difference between the front and rear of the refrigerator, to easily position the refrigerator. The specific implementation steps are detailed below.

[0034] like Figure 6The control principle diagram is shown below. Taking the installation of an embedded refrigerator into a cabinet as an example, the pressure at the front and rear positions of the refrigerator bottom is detected by a pressure sensor installed at the bottom, obtaining the values ​​Tq and Th. Here, the value detected by the first pressure sensor 2 near the door 101 is defined as Tq, and the pressure value detected by the second pressure sensor 3 near the back is defined as Th. The pressure difference between the front and rear is calculated. If the pressure difference is greater than the system set value T0, that is, the pressure near the door 101 is greater, then pushing the refrigerator is easier; if the pressure difference is less than the system value T0, such as... Figure 3 As shown, the controller starts the drive motor, which rotates the worm gear 14. By changing the position of the worm gear 14 relative to the gear, the height of the adjusting seat 11 is adjusted, thereby adjusting the pressure value between the front and back of the refrigerator. When the pressure value reaches the system-set pressure difference T0, the motor stops running, and the worm gear 14 stops rotating. The height difference between the front and back of the refrigerator allows for easy movement. Position sensors are installed on the left, right, and rear sides of the refrigerator. When the refrigerator moves less than a set value relative to the cabinet, an alarm is triggered, thus achieving both movement and limiting of the refrigerator.

[0035] The leveling process of the refrigerator body in this embodiment is described below; After a refrigerator is moved into a cabinet, it needs to be leveled. Traditional refrigerators are leveled by installing two adjustable feet at the bottom. After placing the refrigerator in the desired position, it is tilted, and the length of the adjustable feet screwed into the cabinet is adjusted to change the refrigerator's height. However, with built-in refrigerators, the back and sides are cabinets, making it impossible to use adjustable feet for leveling.

[0036] like Figure 5 The structural diagram, and Figure 6 As shown in the schematic diagram of the control principle, after the built-in refrigerator is inserted into the cabinet, the pressure values ​​Tq and Th at the front and rear positions of the bottom of the refrigerator are detected by the first pressure sensor 2 and the second pressure sensor 3 installed at the bottom. Here, the value detected by the first pressure sensor 2 near the door 101 of the refrigerator is defined as Tq, and the pressure value detected by the second pressure sensor 3 at the back is Th. The magnitudes of Tq and Th are compared.

[0037] If Tq is greater than Th, the controller starts the drive motor, causing the worm gear 14 to rotate counterclockwise. The position of the worm gear 14 relative to the gear section 131 moves backward, lowering the height of the adjusting seat 11 and thus lowering the rear of the refrigerator. During this process, the bottom detector continuously monitors and compares the pressure values ​​before and after. When Tq and Th are equal, the controller stops the motor, the worm gear 14 stops rotating, and the controller simultaneously locks the position of the worm gear 14, achieving refrigerator leveling. If Tq is less than Th, the controller starts the drive motor, causing the worm gear 14 to rotate clockwise. The adjustment process is the same as when Tq is greater than Th, and will not be described further here.

[0038] It should be noted that this application is not limited to built-in refrigerators, but is only described in the context of solving the pain points of built-in refrigerators. The device and control method of this application can be used on ordinary refrigerators to replace the original adjustment feet and roller structure. In particular, it makes moving and leveling large-capacity refrigerators easier, more accurate and convenient.
