Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a door assembly, an oven, and a cooking device. Background Technology

[0002] Currently, most ovens on the market use a conventional bottom-opening design, which requires a significant amount of front space during use, making operation inconvenient. This is especially true as oven capacity increases, further increasing the required front space and diminishing the user experience.

[0003] To address this issue, Chinese invention patent CN113503113A discloses an oven door mechanism and an oven. The oven door mechanism includes a storage shell, a hinge assembly disposed within the storage shell, and an oven door. The hinge assembly includes a hinge fixing seat slidably disposed within the storage shell, a hinge bracket hinged to the hinge fixing seat, and a linkage unit slidably disposed within the hinge fixing seat. The hinge bracket is connected to the oven door. A locking component is provided on the hinge assembly. When the oven door is rotated, the locking component can be locked to the storage shell via the linkage unit.

[0004] Although the aforementioned oven door mechanism can horizontally retract the oven door into the storage shell, so that the oven door no longer occupies the front space of the oven when it is opened, the operating resistance is relatively large when pushing it into the storage shell, which is not labor-saving and results in a poor user experience. Utility Model Content

[0005] In order to overcome the shortcomings and deficiencies of the existing technology, this utility model provides a door assembly, an oven and a cooking device.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a door assembly, which is installed on a housing and includes:

[0008] A support base is provided on one side of the box body, and the support base is adjacent to the opening of the box body;

[0009] A linkage component is movably disposed on the support base along the depth direction of the opening of the housing;

[0010] A door body, one end of which is hinged to the linkage component, has a closed state and an open state, and the state is switched by rotation; when the door body is in the closed state, the door body closes the opening of the housing; when the door body is in the open state, the door body is offset from the opening of the housing, and the door body and the linkage component are arranged side by side on the support base; and

[0011] An elastic component connects the support base and the linkage component. The elastic component provides a driving force to the linkage component to move in a direction away from the opening of the box, so that the door maintains the open state.

[0012] This utility model discloses a door assembly that, through the coordinated operation of a supporting base, a linkage component, a door body, and a resilient component, provides auxiliary driving force when the door is opened, thereby achieving labor-saving operation and improving the user experience. Specifically, the supporting base is located on one side of the housing and adjacent to the opening of the housing, serving as the mounting base for the linkage component, door body, and resilient component. The linkage component is movably mounted on the supporting base along the depth direction of the opening of the housing, so that the linkage component is also located on one side of the housing and adjacent to the opening of the housing. One end of the door body is hinged to the linkage component, and the door body switches between a closed and open state by rotating around the hinge center line between itself and the linkage component. When the door body is in the closed state, the door body closes the opening of the housing and engages with the supporting base and the linkage component. The components are on different horizontal planes; when the door is opened, the door flips relative to the linkage component until it is side by side with the linkage component. At this time, the elastic component applies a driving force to the linkage component and the door, pulling the linkage component and the door in the direction away from the opening of the box, until the linkage component and the door are positioned side by side on the support base. Thus, after the door is opened, it can be placed on the side of the box adjacent to the opening, so that the door no longer occupies the front space of the box after it is opened. At the same time, the driving force provided by the elastic component makes the door push-in action easier and less strenuous, thus improving the user experience.

[0013] In one embodiment, the support base has a receiving cavity. When the door is in the open state, the door and the linkage component are both disposed in the receiving cavity, so as to house the door and the linkage component in the support base, making the door less susceptible to scratches and impacts. At the same time, it can also make the overall shape and structure of the door assembly simpler, thereby improving the aesthetic appearance of the door assembly.

[0014] In one embodiment, the outer wall of the door is provided with an operating component for hand gripping, so as to facilitate the user to close or open the door;

[0015] When the door is in the open state, the operating component is located outside the receiving cavity and abuts against the support base to position the door and ensure that the door is reliably stored in the receiving cavity. At the same time, since the operating component is exposed outside the door, it provides a clear gripping point for the user. When closing the door, the user can directly grasp the operating component, which makes it easy to pull the door out of the receiving cavity and further improves the user experience.

[0016] In one embodiment, the support base has a positioning groove that connects to the receiving cavity and is adapted to the operating component. Thus, when the door is opened, the operating component is retracted into the positioning groove, thereby effectively repositioning the operating component and preventing it from protruding from the support base, maintaining a visually flat overall appearance and avoiding accidental scratches or spatial interference that could be caused by the protruding operating component.

[0017] In one embodiment, the door assembly further includes:

[0018] A guiding mechanism is provided between the supporting base and the linkage component. The guiding mechanism is used to guide the movement of the linkage component to ensure that the linkage component moves along a preset trajectory, thereby avoiding the risk of shaking, jamming or misalignment during the movement, so as to make the door opening and closing smoother and further improve the user experience.

[0019] In one embodiment, the guiding mechanism includes:

[0020] A guide rail is disposed on the support base;

[0021] A movable component is mounted on the linkage component and engages with the guide rail. Thus, when the door opens or closes, an external force (such as a user's push or the driving force of an elastic component) acts on the linkage component, propelling it to move. The movable component then strictly follows the trajectory set by the guide rail, thereby constraining the degrees of freedom of the linkage component and the door to a single, preset direction, achieving precise linear motion. This avoids the risk of wobbling, deviation, or jamming during movement of the linkage component, ensuring highly accurate, smooth, and reliable door opening and closing. By decomposing the moving function into two independent components—the guide rail and the movable component—a modular design is achieved, facilitating manufacturing and subsequent maintenance and replacement. If a single component fails, there is no need to replace the entire support base or linkage component, reducing manufacturing and maintenance costs.

[0022] In one embodiment, the moving component is a roller. Thus, when the linkage component moves, the roller rolls along the guide rail, replacing sliding. Since the rolling friction coefficient is lower than the sliding friction coefficient, the movement of the linkage component on the guide rail is easier and smoother, thereby making it easier to open the door.

[0023] In one embodiment, the guide rail has a guide groove, and guide bars are provided on both the upper and lower sides of the guide groove;

[0024] The roller has a groove arranged around its rotation center line. The groove engages with the guide bar, allowing the roller to roll along it. This creates a clamping structure between the guide bars on the upper and lower sides of the groove and the roller, preventing vertical bouncing or lateral deviation of the roller. This makes the movement of the linkage components and the door more stable and smooth. Simultaneously, it makes it difficult for the roller to accidentally detach from the guide rail, greatly increasing structural stability.

[0025] In one embodiment, the linkage component is provided with a connecting seat;

[0026] The door body has a connecting groove that accommodates the connecting seat, and the connecting groove and the connecting seat are rotatably engaged, that is, the connecting seat is rotatably disposed in the connecting groove to realize the hinged connection between the door body and the linkage component. At the same time, when the door body is opened, the connecting groove plays a role in avoiding the connecting seat, ensuring that the door body and the linkage component are arranged side by side.

[0027] This utility model also provides an oven, including the aforementioned door assembly.

[0028] This oven, employing the aforementioned door assembly, utilizes the coordinated operation of the support base, linkage component, door body, and elastic component to provide auxiliary driving force when the door is opened, thereby achieving effortless operation and improving the user experience. Specifically, the support base is located on one side of the oven body and adjacent to the opening, serving as the mounting base for the linkage component, door body, and elastic component. The linkage component is movably mounted on the support base along the depth direction of the opening, also located on one side of the oven body and adjacent to the opening. One end of the door body is hinged to the linkage component, and the door body switches between a closed and open state by rotating around the hinge center line between itself and the linkage component. When the door body is closed, it seals the opening of the oven body and engages with the support base and linkage component. The components are on different horizontal planes; when the door is opened, the door flips relative to the linkage component until it is side by side with the linkage component. At this time, the elastic component applies a driving force to the linkage component and the door, pulling the linkage component and the door in the direction away from the opening of the box, until the linkage component and the door are positioned side by side on the support base. Thus, after the door is opened, it can be placed on the side of the box adjacent to the opening, so that the door no longer occupies the front space of the box after it is opened. At the same time, the driving force provided by the elastic component makes the door push-in action easier and less strenuous, thus improving the user experience.

[0029] This utility model also provides a cooking device, including the aforementioned door assembly.

[0030] The cooking device of this utility model, by employing the aforementioned door assembly, provides auxiliary driving force when the door is opened through the coordinated cooperation of the supporting base, the linkage component, the door body, and the elastic component, thereby achieving labor-saving operation and improving the user experience. Specifically, the supporting base is disposed on one side of the cabinet and adjacent to the opening of the cabinet, serving as the mounting base for the linkage component, the door body, and the elastic component; the linkage component is movably disposed on the supporting base along the depth direction of the opening of the cabinet, so that the linkage component is also located on one side of the cabinet and adjacent to the opening of the cabinet; one end of the door body is hinged to the linkage component, and the door body switches between a closed state and an open state by rotating around the hinge center line between itself and the linkage component; when the door body is in the closed state, the door body closes the opening of the cabinet and engages with the supporting base and the linkage component. The components are on different horizontal planes; when the door is opened, the door flips relative to the linkage component until it is side by side with the linkage component. At this time, the elastic component applies a driving force to the linkage component and the door, pulling the linkage component and the door in the direction away from the opening of the box, until the linkage component and the door are positioned side by side on the support base. Thus, after the door is opened, it can be placed on the side of the box adjacent to the opening, so that the door no longer occupies the front space of the box after it is opened. At the same time, the driving force provided by the elastic component makes the door push-in action easier and less strenuous, thus improving the user experience.

[0031] The beneficial effects of this utility model are:

[0032] This utility model discloses a door assembly that, through the coordinated operation of a supporting base, a linkage component, a door body, and a resilient component, provides auxiliary driving force when the door is opened, thereby achieving labor-saving operation and improving the user experience. Specifically, the supporting base is located on one side of the housing and adjacent to the opening of the housing, serving as the mounting base for the linkage component, door body, and resilient component.

[0044] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and therefore may vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0045] Please see Figures 1-9This illustration shows a preferred embodiment of a door assembly of the present invention, which is mounted on a housing 1 and includes:

[0046] A support base 11 is provided on one side of the housing 1, and the support base 11 is provided adjacent to the opening 12 of the housing 1.

[0047] Linkage component 2 is movably disposed on the support base 11 along the depth direction of the opening 12 of the housing 1.

[0048] Door 3, one end of which is hinged to linkage component 2, has a closed state and an open state, and the state is switched by rotation; when door 3 is in the closed state, door 3 closes the opening 12 of housing 1; when door 3 is in the open state, door 3 is offset from the opening 12 of housing 1, and door 3 and linkage component 2 are arranged side by side on support base 11; and

[0049] The elastic component 4 connects the support base 11 and the linkage component 2. The elastic component 4 is used to provide the linkage component 2 with a driving force to move in the direction away from the opening 12 of the box body 1 so that the door body 3 maintains the above-mentioned open state.

[0050] The door assembly of this utility model, through the coordinated cooperation of the supporting base 11, the linkage component 2, the door body 3, and the elastic component 4, provides auxiliary driving force when the door body 3 is opened, thereby achieving labor-saving operation and improving the user experience. Specifically, the supporting base 11 is disposed on one side of the housing 1 and adjacent to the opening 12 of the housing 1, serving as the mounting base for the linkage component 2, the door body 3, and the elastic component 4; the linkage component 2 is movably disposed on the supporting base 11 along the depth direction of the opening 12 of the housing 1, so that the linkage component 2 is also located on one side of the housing 1 and adjacent to the opening 12 of the housing 1; one end of the door body 3 is hinged to the linkage component 2, and the door body 3 switches between a closed state and an open state by rotating around the hinge center line between itself and the linkage component 2; when the door body 3 is in the closed state, the door body 3 closes the opening 12 of the housing 1 and is connected to the supporting base 11, The linkage component 2 is on a different horizontal plane. When the door 3 is opened, the door 3 flips relative to the linkage component 2 until it is side by side with the linkage component 2. At this time, the elastic component 4 applies a driving force to the linkage component 2 and the door 3, pulling the linkage component 2 and the door 3 to move away from the opening 12 of the box 1, until the linkage component 2 and the door 3 are positioned side by side on the support base 11. Thus, after the door 3 is opened, it can be placed on the side of the box 1 adjacent to the opening 12, so that the door 3 no longer occupies the front space of the box 1 after it is opened. At the same time, the driving force provided by the elastic component 4 makes the door 3 easier and less strenuous to push in, thus improving the user experience.

[0051] In one embodiment, the support base 11 and the box 1 are integrally arranged together, that is, the support base 11 and the box 1 are an integral structure.

[0052] In one embodiment, the support base 11 is located on top of the housing 1 to house the door 3 on top of the housing 1.

[0053] Of course, in other embodiments, the support base 11 can be located at any of the bottom, left, or right sides of the housing 1.

[0054] In one embodiment, the elastic component 4 may specifically be a tension spring, so that the elastic component 4 has better elastic performance, thereby providing sufficient driving force to the door body 3; at the same time, the two ends of the tension spring have hooks, which facilitates fixing the tension spring between the support base 11 and the linkage component 2.

[0055] Of course, in other embodiments, the elastic component 4 can be any elastic structure such as a common spring or a sheet.

[0056] See Figure 2 In one embodiment, the support base 11 has a receiving cavity 111. When the door 3 is in the open state, the door 3 and the linkage component 2 are both disposed in the receiving cavity 111, so as to realize that the door 3 and the linkage component 2 are housed in the support base 11, making the door 3 less likely to be scratched or bumped. At the same time, it can also make the overall shape structure of the door assembly simpler, thereby improving the appearance of the door assembly.

[0057] Of course, in other embodiments, the linkage component 2 and the door body 3 can be arranged side by side on the outside of the support base 11.

[0058] See Figure 1 In one embodiment, the outer side wall of the door 3 is provided with an operating component 31, which is used for hand gripping so that the user can close or open the door 3.

[0059] When the door 3 is in the open state, the operating component 31 is located outside the receiving cavity 111 and abuts against the support base 11 to position the door 3 and ensure that the door 3 is reliably stored in the receiving cavity 111. At the same time, since the operating component 31 is exposed outside the door 3, it provides a clear gripping point for the user. When closing the door 3, the user can directly grasp the operating component 31, which makes it easy to pull the door 3 out of the receiving cavity 111 and further improves the user experience.

[0060] See Figure 5In one embodiment, the support base 11 has a positioning groove 112, which connects to the receiving cavity 111 and is adapted to the operating component 31. Thus, when the door 3 is opened, the operating component 31 is retracted into the positioning groove 112. This effectively repositions the operating component 31 and prevents it from protruding beyond the support base 11, maintaining a visually flat overall appearance and avoiding accidental scratches or spatial interference that might result from the protrusion of the operating component 31.

[0061] See Figures 2-9 In one embodiment, the door assembly further includes:

[0062] The guide mechanism 5 is located between the support base 11 and the linkage component 2. The guide mechanism 5 is used to guide the linkage component 2 to move, ensuring that the linkage component 2 moves along a preset trajectory, thereby avoiding the risk of shaking, jamming or misalignment during the movement, making the door 3 easier and smoother to open and close, and easier to operate, which helps to further improve the user experience.

[0063] See Figures 2-9 In one embodiment, the guide mechanism 5 includes:

[0064] Guide rail 51 is mounted on the support base 11;

[0065] The moving component 52 is mounted on the linkage component 2 and cooperates with the guide rail 51. Thus, when the door 3 opens or closes, an external force (such as a user's push or the driving force of the elastic component 4) acts on the linkage component 2, propelling it to move. At this time, the moving component 52 strictly follows the trajectory set by the guide rail 51, thereby constraining the degrees of freedom of the linkage component 2 and the door 3 to a single, preset direction, achieving precise linear motion. This avoids the risk of the linkage component 2 wobbling, deviating, or jamming during movement, ensuring highly accurate, smooth, and reliable opening and closing of the door 3. By decomposing the moving function into two independent components, the guide rail 51 and the moving component 52, a modular design is achieved, facilitating processing and subsequent maintenance and replacement. If a single component is damaged, there is no need to replace the entire support base 11 or the linkage component 2, reducing manufacturing and maintenance costs.

[0066] See Figures 2-9 In one embodiment, the moving part 52 is a roller. When the linkage part 2 moves, the roller rolls along the guide rail 51. Since the rolling friction coefficient is lower than the sliding friction coefficient, the movement of the linkage part 2 on the guide rail 51 is easier and smoother, thus making it easier to open the door 3.

[0067] See Figure 3In one embodiment, the guide rail 51 has a guide groove 511, and guide bars 512 are provided on both the upper and lower sides of the guide groove 511.

[0068] The roller has a groove 521, which is arranged around the rotation center line of the roller. The groove 521 engages with the guide bar 512 so that the roller can roll along the guide groove 511. In this way, the guide bars 512 on the upper and lower sides of the guide groove 511 and the roller's groove 521 form a clamping structure, which prevents the roller from jumping in the vertical direction or deviating laterally, making the movement of the linkage component 2 and the door body 3 more stable and smooth. At the same time, it makes it difficult for the roller to accidentally fall off the guide rail 51, greatly increasing the structural stability.

[0069] Of course, in other embodiments, the moving part 52 can be any structure such as a slider, a guide sleeve, etc.

[0070] See Figures 1-9 In one embodiment, the linkage component 2 is provided with a connecting seat 21;

[0071] The door body 3 has a connecting groove 32, which accommodates the connecting seat 21. The connecting groove 32 and the connecting seat 21 are rotatably engaged, that is, the connecting seat 21 is rotatably disposed in the connecting groove 32 to realize the hinged connection between the door body 3 and the linkage component 2. At the same time, when the door body 3 is opened, the connecting groove 32 plays a role in avoiding the connecting seat 21, ensuring that the door body 3 and the linkage component 2 are arranged side by side.

[0072] In one embodiment, the door body 3 is provided with a connecting shaft (not shown in the figure), the connecting shaft is located in the connecting groove 32, the connecting shaft passes through the connecting seat 21 and is rotatably engaged with the connecting seat 21, so that the door body 3 can rotate relative to the linkage component 2.

[0073] This utility model also provides an oven, including the aforementioned door assembly.

[0074] The oven of this invention, by employing the aforementioned door assembly, utilizes the coordinated operation of the support base 11, the linkage component 2, the door 3, and the elastic component 4 to provide auxiliary driving force when the door 3 is opened, thereby achieving labor-saving operation and improving the user experience. Specifically, the support base 11 is disposed on one side of the oven body 1 and adjacent to the opening 12 of the oven body 1, serving as the mounting base for the linkage component 2, the door 3, and the elastic component 4; the linkage component 2 is movably disposed on the support base 11 along the depth direction of the opening 12 of the oven body 1, so that the linkage component 2 is also located on one side of the oven body 1 and adjacent to the opening 12 of the oven body 1; one end of the door 3 is hinged to the linkage component 2, and the door 3 switches between a closed state and an open state by rotating around the hinge center line between itself and the linkage component 2; when the door 3 is in the closed state, the door 3 closes the opening 12 of the oven body 1 and is connected to the support base 11, The linkage component 2 is on a different horizontal plane. When the door 3 is opened, the door 3 flips relative to the linkage component 2 until it is side by side with the linkage component 2. At this time, the elastic component 4 applies a driving force to the linkage component 2 and the door 3, pulling the linkage component 2 and the door 3 to move away from the opening 12 of the box 1, until the linkage component 2 and the door 3 are positioned side by side on the support base 11. Thus, after the door 3 is opened, it can be placed on the side of the box 1 adjacent to the opening 12, so that the door 3 no longer occupies the front space of the box 1 after it is opened. At the same time, the driving force provided by the elastic component 4 makes the door 3 easier and less strenuous to push in, thus improving the user experience.

[0076] The cooking device of this utility model, by employing the aforementioned door assembly, utilizes the coordinated cooperation between the supporting base 11, the linkage component 2, the door 3, and the elastic component 4 to provide auxiliary driving force when the door 3 is opened, thereby achieving labor-saving operation and improving the user experience. Specifically, the supporting base 11 is disposed on one side of the housing 1 and adjacent to the opening 12 of the housing 1, serving as the mounting base for the linkage component 2, the door 3, and the elastic component 4; the linkage component 2 is movably disposed on the supporting base 11 along the depth direction of the opening 12 of the housing 1, so that the linkage component 2 is also located on one side of the housing 1 and adjacent to the opening 12 of the housing 1; one end of the door 3 is hinged to the linkage component 2, and the door 3 switches between a closed state and an open state by rotating around the hinge center line between itself and the linkage component 2; when the door 3 is in the closed state, the door 3 closes the opening 12 of the housing 1 and is connected to the supporting base 11, The linkage component 2 is on a different horizontal plane. When the door 3 is opened, the door 3 flips relative to the linkage component 2 until it is side by side with the linkage component 2. At this time, the elastic component 4 applies a driving force to the linkage component 2 and the door 3, pulling the linkage component 2 and the door 3 to move away from the opening 12 of the box 1, until the linkage component 2 and the door 3 are positioned side by side on the support base 11. Thus, after the door 3 is opened, it can be placed on the side of the box 1 adjacent to the opening 12, so that the door 3 no longer occupies the front space of the box 1 after it is opened. At the same time, the driving force provided by the elastic component 4 makes the door 3 easier and less strenuous to push in, thus improving the user experience.
