Description

Technical Field

[0001] This application relates to the field of refrigerator manufacturing technology, and in particular to a refrigerator. Background Technology

[0002] To meet the aesthetic demands of modern home decoration, refrigerators are usually designed as built-in refrigerators, which achieve visual unity and efficient use of space by embedding the refrigerator flat with the home cabinets.

[0003] Current built-in refrigerators typically have rotating or sliding doors. These door opening methods occupy the front space of the refrigerator. When used in installation spaces such as "U"-shaped spaces or those with small aisles, they can cause space interference, requiring users to avoid obstacles when opening the door to retrieve items, making them very inconvenient to use. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator that can avoid occupying the front space when the door is opened, and is suitable for installation spaces such as "U"-shaped or with small aisles.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A refrigerator, installed in a cabinet, includes:

[0007] The refrigerator body is provided with a first slide rail, which includes a first slide rail and a second slide rail that are connected to each other. The first slide rail extends along the depth direction of the refrigerator, and the second slide rail extends along the width direction of the refrigerator.

[0008] A door for opening / closing the box body, the door being provided with a sliding column, the sliding column being inserted into the first slide rail and slidably connected to the first slide rail;

[0009] The opening process of the cabinet door includes a first stage and a second stage. When the cabinet door is in the first stage, the sliding column slides on the first slide rail; when the cabinet door is in the second stage, the sliding column slides on the second slide rail.

[0010] Understandably, this application divides the door opening process into two stages. Utilizing a first slide rail extending along the refrigerator's depth and a second slide rail extending along its width, the guide column moves the door first towards the refrigerator's depth, removing it from the cabinet, and then moves it towards the refrigerator's width, sliding along the cabinet surface to open the refrigerator. This reduces the door's displacement in the refrigerator's depth direction, minimizing the space occupied in front of the cabinet when the refrigerator is open. It avoids interference with the user's activity space, making it more convenient to use and suitable for "U"-shaped or narrow aisle installation environments. Simultaneously, when opening, the door fits flush with the cabinet surface, not occupying aisle space, achieving better visual unity with the cabinetry and making more efficient use of space.

[0011] In one embodiment, the first slide rail has a first limiting portion disposed at one end of the first slide rail away from the second slide rail; and the first limiting portion can abut against the slide column to limit the opening of the box door.

[0012] And / or, the second slide rail has a second limiting portion, which is disposed on one end of the second slide rail away from the first slide rail; and the second limiting portion can abut against the slide column to limit the movement, thereby providing a damping force for closing the box door.

[0013] Understandably, the first limiting part can limit the sliding column to prevent the door from opening accidentally, and the second limiting part can limit the door to a fixed position after it is opened to prevent the door from closing accidentally, thus improving the user experience of the refrigerator.

[0014] In one embodiment, an angle A is formed between the first slide rail and the second slide rail, wherein A > 90°.

[0015] Understandably, setting the angle between the first and second slide rails to be greater than 90° increases the smoothness of the slide column when switching between the first and second slide rails, reduces the risk of the slide column getting stuck or experiencing severe friction at the turning point, improves the smoothness and reliability of the refrigerator door opening action, and thus extends its service life and user experience.

[0016] In one embodiment, the projected length of the first slide rail in the depth direction of the refrigerator is set to L1, and the gap between the refrigerator and the side of the cabinet in the width direction of the refrigerator is set to L2, wherein L1 < L2.

[0017] Furthermore, the projection length of the first slide rail in the width direction of the refrigerator is set to L3, and the thickness of the door is set to L4, wherein L3 > L4.

[0018] Understandably, this design prevents the refrigerator door from interfering with the cabinet on the side of the refrigerator in the width direction when the sliding column moves along the first slide rail, ensuring the refrigerator can be smoothly installed into the cabinet while allowing the cabinet to open and close normally.

[0019] In one embodiment, the housing is further provided with a second slide rail, and the door is further provided with a slider, the slider being slidably connected to the second slide rail for guiding the movement of the door relative to the housing.

[0020] In one embodiment, the second slide extends along the width direction of the refrigerator;

[0021] The slider is slidably mounted on the refrigerator door via a guide post, and the slider is capable of sliding relative to the guide post in the depth direction of the refrigerator.

[0022] Understandably, the sliding cooperation between the slider and the second slide rail ensures that the door can move in the width direction of the refrigerator when the slide column slides on the second slide rail. Furthermore, the slider and guide column design increases the connection structure between the door and the refrigerator body to prevent the door from tilting relative to the refrigerator body and improve the stability of the door during movement.

[0023] In one embodiment, the number of guide posts is set to multiple, the multiple guide posts are arranged at intervals along the width direction of the refrigerator, and the multiple guide posts are simultaneously arranged through the slider;

[0024] Each of the guide posts is fitted with a first elastic element, which abuts against the slider and provides an elastic force to the guide post to move toward the housing.

[0025] Understandably, setting multiple guide pillars can prevent stress concentration between the door and the slider, thus avoiding structural damage. This increases the stability of the connection between the door and the slider. Furthermore, the first elastic element provides the guide pillars with an elastic force that moves towards the refrigerator body. When the slider is located on the first slide rail, it has a driving force to move away from the first slide rail in the depth direction of the refrigerator, ensuring that the refrigerator body can close normally. In other words, the guide pillars can make the door tend to move towards the refrigerator body, reducing the amount of force required for the user to close the door and making it easier to close.

[0026] In one embodiment, the first slide rail and the second slide rail are disposed at the top of the box body;

[0027] The door is provided with a mounting bracket, and the sliding column and the slider are both mounted on the mounting bracket.

[0028] In one embodiment, the sliding column is located at the top of the door;

[0029] The bottom of the box door is rotatably equipped with a pulley, the outer wheel surface of the pulley abuts against the box body, and the pulley can roll relative to the box body under the action of the box door.

[0030] Understandably, when the sliding column slides on the second slide rail, the pulley installed at the bottom of the door against the box body can cooperate with the door to roll relative to the box body, thereby reducing the contact area between the door and the box body, reducing sliding friction, and thus increasing the smoothness of the door sliding open or close relative to the box body.

[0031] In one embodiment, a frame is rotatably mounted at the bottom of the door, and a pulley is rotatably mounted on one end of the frame.

[0032] The door is also provided with a second elastic element, which abuts against the frame in a pre-deformed manner to provide an elastic force for the frame to drive the pulley toward the box.

[0033] Understandably, the second elastic element ensures that the pulley and the refrigerator body are in contact, thus improving the stability of the door's movement relative to the refrigerator body during the opening and closing process.

[0034] Compared with existing technologies, the refrigerator described herein divides the door opening process into two stages. Utilizing a first slide rail extending along the refrigerator's depth and a second slide rail extending along its width, a guide column moves the door first towards the refrigerator's depth, removing it from the cabinet, and then moves it towards the refrigerator's width, sliding along the cabinet surface to open the refrigerator. This reduces the door's displacement in the refrigerator's depth direction, minimizing the space occupied in front of the cabinet when the refrigerator is open, avoiding interference with the user's activity space, and making it more convenient to use. It is suitable for "U"-shaped or narrow aisle installation environments. Furthermore, when the door is opened, it fits flush with the cabinet surface, without occupying aisle space, achieving better visual unity with the cabinetry and making more efficient use of space.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0053] Please see Figures 1 to 10This application provides a refrigerator 100, which is mainly used for flush installation in a cabinet 200. By improving the matching structure of the cabinet body 10 and the door 20, it is made so that the door will not occupy the front space of the refrigerator when it is opened, so that it can be used in "U" shaped kitchens or installation spaces with small aisles, avoiding space interference, so that users do not need to avoid the space when opening the door to access items, thus improving the user experience.

[0054] Specifically, the refrigerator 100 includes a cabinet 10 and a door 20. The cabinet 10 is provided with a first slide rail 11, which includes a first slide rail 111 and a second slide rail 112 that are interconnected. The first slide rail 111 extends along the depth direction x of the refrigerator 100, and the second slide rail 112 extends along the width direction y of the refrigerator 100. The door 20 is used to open / close the cabinet 10. The door 20 is provided with a sliding post 21, which is partially inserted into the first slide rail 11 and slidably connected to it. The opening process of the door 20 includes a first stage and a second stage. When the door 20 is in the first stage, the sliding post 21 slides on the first slide rail 111. When the door 20 is in the second stage, the sliding post 21 slides on the second slide rail 112.

[0055] Understandably, this application divides the opening process of the cabinet door 20 into two stages. Utilizing a first slide rail 111 extending along the depth x direction of the refrigerator 100 and a second slide rail 112 extending along the width y direction of the refrigerator 100, the guide column 21 moves the cabinet door 20 first along the depth x direction of the refrigerator 100 to remove it from the cabinet 200, and then moves it along the width y direction of the refrigerator 100, i.e., sliding along the cabinet surface, thus opening the refrigerator 100. This reduces the displacement of the cabinet door 20 along the depth x direction of the refrigerator 100, reducing the space occupied in front of the cabinet 200 when the refrigerator 100 is open. It avoids interference with the user's activity space, making it more convenient to use and suitable for "U"-shaped or narrow aisle installation environments. Simultaneously, when opening, the cabinet door 20 is flush with the cabinet surface, without occupying aisle space, better achieving visual unity with the flush-mounted cabinet 200, and making more efficient use of space.

[0056] Here, the cabinet front refers to the side of the refrigerator 100 facing the user in the depth x direction when the cabinet 200 is actually in use.

[0057] like Figures 3 to 6As shown, an angle A is formed between the first slide rail 111 and the second slide rail 112, where A > 90°. This arrangement increases the smoothness of the sliding column 21 when switching between the first slide rail 111 and the second slide rail 112, reduces the risk of the sliding column 21 getting stuck or experiencing severe friction at inflection points, improves the smoothness and reliability of the refrigerator 100's door opening action, and thus extends its service life and user experience.

[0058] Here, the included angle A formed between the first slide rail 111 and the second slide rail 112 can be set to 95°, 100°, 120°, etc. Of course, it is not limited to this, and the specific included angle formed between the first slide rail 111 and the second slide rail 112 can be determined according to the actual situation.

[0059] Furthermore, the projection length of the first slide rail 111 in the depth direction x of the refrigerator 100 is set to L1, the gap between the side of the refrigerator 100 and the cabinet 200 in the width direction y of the refrigerator 100 is set to L2, where L1 < L2; and the projection length of the first slide rail 111 in the width direction y of the refrigerator 100 is set to L3, the thickness of the cabinet door 20 is set to L4, where L3 > L4. Understandably, the setting of L1 < L2 ensures that when the sliding column 21 moves along the first slide rail 111 towards the second slide rail 112, the door 20 avoids interference with the cabinet 200 on the side of the refrigerator 100 in the length direction y, which is closer to the direction of movement. The setting of L3 > L4 ensures that when the refrigerator 100 is opened, the door 20 can move completely to the outside of the cabinet 200 in the depth direction x of the refrigerator 100, so as to ensure that the door 20 can move along the second slide rail 112. That is, through the above settings, interference between the door 20 and the cabinet 200 on the side of the refrigerator 100 in the width direction y is avoided when the sliding column 21 moves along the first slide rail 111. While the refrigerator 100 is flush-fitted into the cabinet 200, the normal opening and closing of the cabinet 10 is ensured.

[0060] In one embodiment, the first slide rail 111 has a first limiting portion (not shown), which is disposed at one end of the first slide rail 111 away from the second slide rail 112; and the first limiting portion can abut against the sliding post 21 to limit the opening of the door 20; and / or, the second slide rail 112 has a second limiting portion 1121, which is disposed at one end of the second slide rail 112 away from the first slide rail 111; and the second limiting portion 1121 can abut against the sliding post 21 to limit the closing of the door 20. Thus, the first limiting portion can limit the sliding post 21 to prevent the door 20 from opening accidentally, and the second limiting portion 1121 can limit the door 20 to a fixed position after it is opened to prevent it from closing accidentally, thus improving the user experience of the refrigerator 100.

[0061] Here, the first limiting part and the first slide rail 111 are angled together along their center lines in the extending direction to limit the sliding column 21, preventing the sliding column 21 from moving along the first slide rail 111 when the door is closed, thus avoiding a situation where the door is not closed tightly and affecting the energy consumption of the refrigerator 100. Of course, it is not limited to this; the first limiting part can also be configured as a snap-fit ​​component with a snap-fit ​​groove, etc., to snap into the sliding column 21 and limit it when the refrigerator 100 is fully closed. The specific configuration of the first limiting part can be determined according to the actual situation.

[0062] Furthermore, the second limiting part 1121 and the second slide rail 112 are angled together along their center lines in the extending direction.

[0063] In one embodiment, the housing 10 is further provided with a second slide rail 12, and the door 20 is further provided with a slider 22. The slider 22 is slidably connected to the second slide rail 12 and is used to guide the movement of the door 20 relative to the housing 10.

[0064] Specifically, the second slide rail 12 extends along the width direction y of the refrigerator 100; the slider 22 is slidably mounted on the door 20 via the guide post 23, and the slider 22 can slide relative to the guide post 23 in the depth direction x of the refrigerator 100. Thus, through the sliding engagement of the slider 22 and the second slide rail 12, it is ensured that when the slide post 21 slides on the second slide rail 112, the door 20 can maintain its movement in the width direction y of the refrigerator 100. Furthermore, the arrangement of the slider 22 and the guide post 23 increases the connection between the door 20 and the refrigerator body 10, preventing the door 20 from tilting relative to the refrigerator body 10 and improving the stability of the door 20 during movement.

[0065] Furthermore, the number of guide pillars 23 is set to multiple, and the multiple guide pillars 23 are arranged at intervals along the width direction y of the refrigerator 100. The multiple guide pillars 23 simultaneously penetrate the slider 22. Each guide pillar 23 is fitted with a first elastic element 24, which abuts against the slider 22 to provide an elastic force for the guide pillar 23 to move towards the cabinet 10. It is understood that setting multiple guide pillars 23 can avoid stress concentration between the door 20 and the slider 22, thus preventing structural damage and increasing the stability of the connection between the door 20 and the slider 22. Furthermore, the first elastic element 24 provides an elastic force for the guide pillars 23 to move towards the cabinet 10, so that when the slider 21 is located on the first slide rail 111, it has a driving force to move away from the first slide rail 111 in the depth direction x of the refrigerator 100, ensuring that the cabinet 10 can be closed normally. That is, the guide pillars 23 can make the door 20 tend to move towards the cabinet 10, reducing the force required for the user to close the door and making it easier to close.

[0066] Here, the guide posts 23 can be set to two, three, or five. Of course, it is not limited to this, and the specific number of guide posts 23 can be determined according to the actual situation. In this embodiment, two guide posts 23 are set.

[0067] In this embodiment, the first elastic element 24 is configured as a spring structure. Of course, it is not limited to this, and the first elastic element 24 can be configured according to the actual situation.

[0068] In one embodiment, the first slide rail 11 and the second slide rail 12 are located at the top of the cabinet 10 in the height direction z of the refrigerator 100; the cabinet door 20 is provided with a mounting bracket 25, and the sliding column 21 and the slider 22 are both mounted on the mounting bracket 25.

[0069] One end of the first elastic element 24 is fixed to the mounting bracket 25, and the other end abuts against the slider 22.

[0070] like Figures 7 to 10 As shown, a sliding column 21 is positioned at the top of the refrigerator door 20. A pulley 26 is rotatably mounted on the bottom of the refrigerator door 20 at its height (z) relative to the refrigerator body 10. The outer surface of the pulley 26 abuts against the refrigerator body 10, and the pulley 26 can roll relative to the refrigerator body 10 under the influence of the refrigerator door 20. Thus, when the sliding column 21 slides on the second slide rail 112, the pulley 26 can cooperate with the refrigerator door 20 to roll relative to the refrigerator body 10, reducing the contact area between the refrigerator door 20 and the refrigerator body 10, reducing sliding friction, and thereby increasing the smoothness of the refrigerator door 20 when sliding open or closed relative to the refrigerator body 10.

[0071] In one embodiment, a frame 27 is rotatably mounted at the bottom of the door 20, and a pulley 26 is rotatably mounted on one end of the frame 27. A second elastic element 28 is also provided on the door 20. The second elastic element 28 abuts against the frame 27 in a pre-deformed manner, providing an elastic force for the frame 27 to drive the pulley 26 to rotate toward the refrigerator body 10. It is understood that by providing an elastic force for the frame 27 to drive the pulley 26 to rotate toward the refrigerator body 10, the second elastic element 28 ensures that when the door 20 moves along the first slide rail 11, the pulley 26 remains abutting against the refrigerator body 10 and drives the door 20 to roll on the refrigerator body 10, thereby ensuring the smoothness of the door 20's movement relative to the refrigerator body 10 and improving the stability of the door 20's movement relative to the refrigerator body 10 during the opening and closing of the refrigerator 100.

[0072] Furthermore, a ramp 271 is provided on the frame 27. The ramp 271 is located between the second elastic member 28 and the pulley 26, and the angle between the ramp 271 and the side of the box 10 facing the door 20 is less than 90 degrees. One end of the second elastic member 28 is located on the frame 27, and the other end elastically abuts against the side of the ramp 271 away from the box 10, so that the ramp 271 provides the above-mentioned elastic force to drive the pulley 26 to rotate toward the box 10.

[0073] Here, the angle between the inclined plate 271 and the side of the box body 10 facing the box door 20 can be set to 30°, 45°, 70°, etc. Of course, it is not limited to this, and the specific angle between the inclined plate 271 and the side of the box body 10 facing the box door 20 can be determined according to the actual situation.

[0074] Here, the second elastic element 28 adopts a structure such as a torsion spring. Of course, it is not limited to this, and the second elastic element 28 can be set to other structures with restoring force.

[0075] In one embodiment, the aforementioned sliding column 21 can be controlled by a voice module. It is connected to the controller, the voice receiving module, and the voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the sliding column 21 to perform door opening or closing operations, causing the sliding column 21 to move along the first slide rail 11 to drive the door 20 to open or close the refrigerator body 10, thereby realizing intelligent opening and closing of the refrigerator and improving the user experience.

[0076] It should be understood that, unless otherwise specified in this document, there is no strict order to the above steps. These steps can be performed sequentially or in any other order, and the specific steps can be determined according to the actual situation.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
