[0001] This utility model relates to the field of electrical appliance housing design technology, and more specifically, to a housing assembly and a kitchen appliance having the same. Background Technology

[0002] In existing technologies, kitchen appliances (such as dispensing boxes and cooking appliances) typically have a working cavity, which is opened or sealed by a door. The door is usually pivotally connected to the housing. However, users experience the following pain points during use: 1. The sealing effect of the working cavity is poor when the door is closed; 2. The door is difficult for users to operate when opening; 3. The door cannot remain in a certain open position for an extended period of time.

[0003] There is currently no effective solution to the above technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide a housing assembly and a kitchen appliance having the same, so as to at least solve the problem of poor sealing performance of the housing and door of kitchen appliances in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a housing assembly is provided, comprising: a housing having a cavity within it; a rotating shaft located within the cavity and rotatably connected to the housing; a door connected to the rotating shaft, the door having a closed position that seals the cavity and multiple open positions that at least partially open the cavity; a first connecting rod located within the cavity, a first end of the first connecting rod connected to the rotating shaft, the geometric center of the first end of the first connecting rod coinciding with the rotation center of the rotating shaft; and an elastic element located within the cavity, a first end of the elastic element rotatably connected to a second end of the first connecting rod, and a second end of the elastic element connected to the housing; wherein, during the process of the door moving from the closed position to the open position, the rotating shaft rotates about its own central axis in a first direction; when the door is in the closed position, the elastic element is in a compressed state, and the direction of the torque of the elastic force of the elastic element on the rotating shaft is a second direction, which is opposite to the first direction.

[0006] Furthermore, the first direction is counterclockwise, and the second direction is clockwise.

[0007] Furthermore, the first direction is clockwise, and the second direction is counterclockwise.

[0008] Furthermore, a first straight line is formed between the rotation center of the rotating shaft and the second end of the elastic element. When the door is in the closed position, the connection point between the elastic element and the first connecting rod is located on the side of the first straight line away from the door.

[0009] Furthermore, when the door is in the partially open position, the elastic element is in a compressed state, and the direction of the torque of the elastic force of the elastic element on the rotating shaft is a third direction, which is the same as the first direction.

[0010] Furthermore, among the multiple open positions is a dead position. When the door is in the dead position, the first link and the elastic element are collinear. During the process of the door moving from the closed position to the dead position, the elastic element is in a compressed state, and the rotating shaft rotates around its own central axis in a first direction. The direction of the torque of the elastic force of the elastic element on the rotating shaft is a second direction.

[0011] Furthermore, when the door is in the dead position, the angle between the door and the vertical plane is A1, where 25°≥A1≥15°.

[0012] Furthermore, the multiple opening positions include opening the cavity to its maximum limit position. During the process of the door moving from the dead point position to the limit position, the elastic element is in a compressed state, and the rotating shaft rotates around its own central axis in a first direction. The direction of the torque of the elastic force of the elastic element on the rotating shaft is a third direction.

[0013] Furthermore, when the door is in the closed position, the door is parallel to the vertical plane, and / or, when the door is in the extreme position, the door is perpendicular to the vertical plane.

[0014] Furthermore, both the first direction and the third direction are counterclockwise.

[0015] Furthermore, a first straight line is formed between the rotation center of the rotating shaft and the second end of the elastic element. During the process of the door moving from the dead point position to the limit position, the connection point between the elastic element and the first connecting rod is located on the side of the first straight line closer to the door.

[0016] Furthermore, the housing assembly also includes a drive assembly, which is at least partially located within the cavity and connected to the housing. The drive assembly is used to drive the door to the open or closed position.

[0017] Furthermore, the rotating shaft and the drive assembly are respectively located on opposite sides in the height direction of the housing, or the rotating shaft and the drive assembly are respectively located on opposite sides in the width direction of the housing.

[0018] Furthermore, the second end of the elastic element is connected to the side of the housing where the drive assembly is located.

[0019] Furthermore, the drive assembly includes a power source and an actuator. The power source is connected to the housing, the actuator is connected to the power source, the actuator is movably disposed relative to the housing, and the actuator is connected to the door. Alternatively, the end of the actuator is disposed adjacent to the door, so that the actuator has a driving state that abuts against the door and drives the door to move. The power source is used to drive the actuator to move relative to the housing, so as to drive the door to be in the open or closed position.

[0020] Furthermore, the housing assembly also includes a second link, one end of which is connected to a pivot, and the other end of which is connected to the door body, so that the pivot rotates around its own axis to drive the door body to move relative to the housing.

[0021] Furthermore, the second link has an arc-shaped structure and is recessed towards the door body.

[0022] Furthermore, the housing assembly also includes a partition that divides the cavity into at least a material box cavity and a drive cavity. The second connecting rod is located in the material box cavity, and the rotating shaft passes through a mounting hole in the partition. The first connecting rod and the elastic element are both located in the drive cavity.

[0023] Furthermore, the housing assembly also includes an elastic element mounting base, which is connected to the housing, and the second end of the elastic element is rotatably connected to the elastic element mounting base.

[0024] Furthermore, the length direction of the first connecting rod is perpendicular to the axial direction of the rotating shaft, and / or, the length direction of the elastic element is perpendicular to the axial direction of the rotating shaft.

[0025] According to one aspect of the present invention, a kitchen appliance is provided, including a housing assembly, wherein the housing assembly is the aforementioned housing assembly.

[0026] By applying the technical solution of this utility model, by setting an elastic element and a first connecting rod to cooperate with the rotating shaft, when the door is in the closed position, the elastic element is in a compressed state. The direction of the torque of the elastic force of the elastic element on the rotating shaft is opposite to the direction of rotation of the rotating shaft. This torque drives the rotating shaft to resist the tendency of the rotating shaft to rotate in the first direction, and finally prevents the rotating shaft from moving to the open position, thereby improving the sealing performance of the shell and the door.

[0049] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0050] Referring to Figures 1 to 7, a housing assembly is provided according to a specific embodiment of this application.

[0051] To illustrate the internal structure of the housing assembly, Figure 1 shows a schematic diagram of the kitchen appliance housing after the top and side panels have been removed (the top and side panels can be integrally formed). The housing assembly includes: a housing 10, a pivot 20, a first connecting rod 40, and an elastic element 50. The housing 10 has a cavity. The pivot 20 is located within the cavity and is rotatably connected to the housing 10. A door 30 is connected to the pivot 20, and has a closed position that seals the cavity, and multiple open positions that at least partially open the cavity. The first connecting rod 40 is located within the cavity, and its first end is connected to the pivot 20. The geometric center of the first end of the first connecting rod 40 coincides with the rotation center of the pivot 20. The elastic element 50 is located inside the cavity. The first end of the elastic element 50 is rotatably connected to the second end of the first connecting rod 40, and the second end of the elastic element 50 is movably connected to the housing 10. During the process of the door 30 moving from the closed position to the open position, the rotating shaft 20 rotates around its own central axis in the first direction. When the door 30 is in the closed position, the elastic element 50 is in a compressed state. The direction of the torque of the elastic force of the elastic element 50 on the rotating shaft 20 is the second direction, which is opposite to the first direction.

[0052] The torque of the elastic force of the elastic element 50 about the rotating shaft 20 is a vector quantity, the magnitude of which is equal to the product of the elastic force and the lever arm. The lever arm is the perpendicular distance from the point of application of the elastic element to the center of rotation of the shaft. If the first end of the elastic element is connected to the second end of the first connecting rod 40 by rotation, the length of the lever arm can be obtained from the straight-line distance from the connection point of the elastic element to the center of the rotating shaft. The torque M can be calculated using the formula M = F * r, where F is the elastic force of the elastic element and r is the length of the lever arm. The direction of the torque can be determined using the right-hand rule. When the door 30 is closed, the direction of the elastic force of the elastic element 50 is the direction that restores it to its original length. If the elastic element is compressed, the direction of its restoring force will point to its uncompressed state. Then the direction of the torque can be determined. For example, if the first direction is counterclockwise (observed from the outside), then the second direction (torque direction) is clockwise.

[0053] By applying the technical solution of this utility model, by setting the elastic element 50 and the first connecting rod 40 to cooperate with the rotating shaft 20, when the door 30 is in the closed position, the elastic element 50 is in a compressed state. The direction of the torque of the elastic force of the elastic element 50 on the rotating shaft 20 is opposite to the rotation direction of the rotating shaft 20. This torque drives the rotating shaft 20 to resist the tendency of the rotating shaft 20 to rotate in the first direction, and finally prevents the rotating shaft from moving to the open position, thereby improving the sealing performance of the shell and the door.

[0054] In an optional embodiment, the rotatable connection between the first end of the elastic member 50 and the second end of the first connecting rod 40 can be achieved using the following technical solution: the second end of the first connecting rod 40 has two opposing forks, each fork having a pin hole, and a rotational space is formed between the two forks. The first end of the elastic member 50 extends into this rotational space. A pin passes sequentially through one pin hole, the elastic member, and the other pin hole to rotatably connect the first end of the elastic member 50 to the second end of the first connecting rod 40.

[0055] In another optional embodiment, the second end of the elastic element 50 is rotatably connected to the housing 10. Specifically, the housing 10 is provided with a rotating support seat, and the second end of the elastic element 50 is connected to the rotating support seat by a rotating pin. The first end of the elastic element 50 is rotated around the central axis of the rotating pin by the rotating pin.

[0056] In another alternative embodiment, the first end of the first link 40 is fixedly connected to the rotating shaft 20, which can rotate relative to the housing through a bearing, thereby driving the first link 40 to rotate.

[0057] In existing kitchen appliances, the door seal is often inadequate when closed, making it difficult for users to open or close, and the door cannot stably remain in a specific position during the opening process. The connection between the door and the housing is improved by using a first connecting rod connected to a pivot and a spring-loaded element (such as a pneumatic spring). When the door is closed, the spring-loaded element is compressed, providing a torque opposite to the opening direction, thus enhancing the seal. The first end of the spring-loaded element is rotatably connected to the second end of the first connecting rod, and the second end is movably connected to the housing, ensuring that the spring-loaded element generates a torque in a specific direction during door opening, thereby providing assistance when the door is partially open.

[0058] The technical solution of this application achieves the following technical effects: 1. It improves the sealing performance of the door when closed, reduces leakage in the working cavity, and enhances the performance and efficiency of kitchen appliances. 2. It provides assistance during the door opening process, reducing the user's operational burden and improving the user experience. 3. It enables the door to remain stably in a specific position during the opening process, increasing ease of use.

[0059] Furthermore, the first direction is counterclockwise, and the second direction is clockwise.

[0060] Furthermore, the first direction is clockwise, and the second direction is counterclockwise.

[0061] Furthermore, a first straight line is formed between the rotation center of the rotating shaft 20 and the second end of the elastic member 50. When the door 30 is in the closed position, the connection point between the elastic member 50 and the first connecting rod 40 is located on the side of the first straight line away from the door 30.

[0062] When the door 30 is in the closed position, the elastic element 50 is compressed, and the resulting elastic force acts on the door 30 through the first connecting rod 40 and the pivot 20, making it fit more tightly against the housing 10. This force direction helps to enhance the sealing effect between the door 30 and the housing 10, preventing leakage of the working cavity. This arrangement ensures that the door 30 has a stable torque acting on the pivot 20 when in the closed position, keeping it in the closed position and preventing accidental opening due to slight external disturbances, thus increasing safety. Furthermore, when the door 30 is in the partially open position, the elastic element 50 is in a compressed state, and the direction of the torque of the elastic force of the elastic element 50 on the pivot 20 is a third direction, which is the same as the first direction.

[0063] As shown in Figure 5, among the multiple open positions is the dead position. When the door 30 is in the dead position, the first connecting rod 40 and the elastic element 50 are collinear. During the process of the door 30 moving from the closed position to the dead position, the elastic element 50 is in a compressed state, and the rotating shaft 20 rotates around its own central axis in the first direction. The direction of the torque of the elastic force of the elastic element 50 on the rotating shaft 20 is the second direction.

[0064] In an optional embodiment, as shown in Figure 4, when the door is in the closed position, a nitrogen spring applies a clockwise torque to the door, holding it in place so that the door presses against the seal, forming a seal after the door is closed.

[0065] As shown in Figure 5, when the door is opened to a tilt angle of about 20 degrees and reaches the dead point of the door, the nitrogen spring will not drive the pivot to rotate.

[0066] With the dead-point design, the opening and closing process of the door 30 can be smoother, and users can more easily control the degree of opening and closing of the door 30. This avoids the impact and noise that may be caused when the door 30 is suddenly opened or closed, and improves the durability and comfort of the equipment.

[0067] Furthermore, the multiple opening positions include opening the cavity to its maximum limit position. During the process of the door 30 moving from the dead point position to the limit position, the elastic element 50 is in a compressed state, and the rotating shaft 20 rotates around its own central axis in a first direction. The direction of the torque of the elastic force of the elastic element 50 on the rotating shaft 20 is a third direction.

[0068] In an optional embodiment, when the door is tilted at an angle of about 20 degrees and reaches the dead point of the door, the door is driven to continue to tilt upwards. The nitrogen spring will generate a counterclockwise torque on the pivot. When this torque can overcome the clockwise torque of the door's weight on the pivot, the door will be opened automatically, creating a user experience of door opening assistance.

[0069] As shown in Figure 6, when the door is opened to 90 degrees, the direction of the torque of the nitrogen spring on the pivot is counterclockwise, which is the same as the direction of the torque of gravity on the pivot. When the torque generated by the nitrogen spring is greater than the torque of the door panel on the pivot, the door is supported by the nitrogen spring, and the door is kept in the open position.

[0070] By introducing the concepts of dead point position and extreme position, the collinear arrangement of the connecting rod and elastic element at the dead point position provides assistance to the door in the initial stage of opening, while at the extreme position the elastic element provides a torque that balances the weight of the door, ensuring the stability of the door.

[0071] As the door 30 continues to open from its dead position to its limit position, the direction of the torque will also change from the second direction (opposite to the door opening direction) to the third direction (forward to the door opening direction). This torque conversion mechanism can automatically provide assistance for the further opening of the door 30, allowing the door 30 to easily reach its maximum opening. At the same time, it generates resistance when closing, preventing the door 30 from falling freely under the action of gravity, thus improving the safety and convenience of the equipment.

[0072] Furthermore, both the first direction and the third direction are counterclockwise.

[0073] As shown in Figure 4, a first straight line is formed between the rotation center of the rotating shaft 20 and the second end of the elastic member 50. During the process of the door body 30 moving from the dead point position to the limit position, the connection point between the elastic member 50 and the first connecting rod 40 is located on the side of the first straight line closer to the door body 30.

[0074] Furthermore, the housing assembly also includes a drive assembly 90, which is at least partially located within the cavity and connected to the housing 10. The drive assembly 90 is used to drive the door 30 to the open or closed position.

[0075] The addition of the drive component 90 enables the opening and closing process of the door 30 to be automated. Users do not need to operate it manually and can control the drive component 90 to work through buttons, touch screens or sensors, thereby automatically opening or closing the door 30, improving the convenience and intelligence of the equipment.

[0076] The drive assembly 90 ensures that the door 30 is accurately aligned with the closing position when closed, avoiding the phenomenon that the door 30 is not fully closed due to improper operation or insufficient force by the user, thereby improving the sealing performance and overall safety of the equipment.

[0077] With the drive component 90, users can quickly and smoothly control the opening and closing of the door 30, avoiding the instability, noise and friction that may be caused by manual operation, and providing a smoother and more comfortable user experience.

[0078] The drive assembly 90 can also be integrated with other functional modules of the device (such as sensors and controllers) to achieve more complex functions, such as automatically opening or closing the door 30 according to the device status, or automatically stopping the movement of the door 30 when a foreign object is detected, thereby improving the intelligence and functionality of the device. Placing part of the drive assembly 90 inside the cavity can make more efficient use of the internal space of the device, reduce the overall external size of the device, and make the device more compact, making it easier to place and use in space-constrained environments such as kitchens.

[0079] Furthermore, the rotating shaft 20 and the drive assembly 90 are respectively arranged on opposite sides of the housing 10 in the height direction, or on opposite sides of the housing 10 in the width direction. This dual-side arrangement, similar to the dual-side drive mechanism of an air conditioner's air deflector, allows the rotating shaft 20 and drive assembly 90 to drive opposite sides of the housing 10, causing the door to move along a preset trajectory and thus push the door out. This arrangement effectively utilizes the internal space of the housing 10; in the height direction, the vertical space of the housing can be utilized; and in the width direction, the horizontal space of the housing can be utilized, resulting in a more compact internal structure, reducing the overall size of the equipment, and improving space efficiency.

[0080] Furthermore, the second end of the elastic element 50 is connected to the side of the housing 10 where the drive assembly 90 is located.

[0081] Furthermore, the drive assembly 90 includes a power source and an actuator. The power source is connected to the housing 10, and the actuator is connected to the power source. The actuator is movably disposed relative to the housing 10. The actuator is connected to the door 30, or the end of the actuator is disposed adjacent to the door 30, so that the actuator has a driving state that abuts against the door 30 and drives the door 30 to move. The power source is used to drive the actuator to move relative to the housing 10, so as to drive the door 30 to be in the open position or the closed position.

[0082] Referring to Figure 7, specifically, the drive assembly 90 includes a guide rail 21 and a slider 22. The guide rail 21 is connected to the housing 10. A gap is provided between the guide rail 21 and the housing 10. The slider 22 is slidably connected to the guide rail 21 so that the slider 22 can drive the door 30 to a closed position and an open position. The angle formed with the horizontal plane is different when the door assembly is in different open positions.

[0083] The slider 22 is an actuator. The slider 22 can be fixedly connected to the door body 30 or set adjacent to the door body 30.

[0084] By adopting the technical solution of the above embodiment, by setting a first gap between the guide rail 21 and the housing 10, the slider 22 is less likely to accumulate oil fumes during the process of driving the door 30. Compared with the existing structure, the possibility of jamming is reduced in this solution, and the movement resistance is smaller. The parallelism requirement between the guide rail 21 and the slider 22 is also reduced, which improves the fault tolerance of the overall structure and effectively solves the problem of poor working stability of the housing component in the prior art.

[0085] As shown in Figure 7, the housing assembly also includes a discharge assembly 3 and a receiving box. The discharge assembly 3 is located within the receiving cavity 5 and has a discharge port. The receiving box has a receiving position located at the bottom of the discharge port and a conveying position that moves at least partially outside the receiving cavity 5. The receiving box is connected to at least one of the slider 22 and the door 30. When the receiving box is connected to the slider 22, the slider 22 drives the receiving box to be in the receiving position and the conveying position. When the receiving box is connected to the door 30, the slider 22 drives the door 30, thereby causing the receiving box to be in the receiving position and the conveying position.

[0086] The drive assembly 90 also includes a base 23. The base 23 is connected to the first side wall of the housing 10, and a guide rail 21 is connected to the base 23. The guide rail 21 is disposed on the side of the base 23 away from the first side wall, and a second gap is provided between the guide rail 21 and the base 23.

[0087] Specifically, the second gap is smaller than the first gap. For example, when the gap between the guide rail and the first sidewall is 5mm, the gap between the guide rail 21 and the first sidewall is 3mm. However, since there is a gap between the guide rail 21 and the base 23, it still serves to prevent oil fume deposition.

[0088] In one optional embodiment, the guide rail 21 is an optical axis, meaning its circumferential surface is a smooth curved surface with certain surface roughness requirements. The optical axis guide rail solution allows for non-destructive replacement of existing linear guide rails, facilitating maintenance of commercially available machines.

[0089] Furthermore, the first sidewall is the bottom or top wall of the receiving cavity 5, and the guide rail 21 is a shaft-like structure with the axial direction of the guide rail 21 parallel to the first sidewall.

[0090] This layout allows the guide rail 21 to occupy less space in the vertical direction, while limiting the working direction of the slider to be parallel to the first side wall. The layout of the guide rail axis being parallel to the first side wall makes the operation of the housing assembly in the discharge direction smoother and more stable, reducing the shaking and spillage of the seasoning during the conveying process.

[0091] Furthermore, the pattern formed by the radial cross-section of the guide rail 21 is circular or elliptical.

[0092] The circular or elliptical guide rail cross-section design provides more uniform sliding resistance, ensuring smooth movement of the slider on the guide rail and guaranteeing the stability of the feeding process and product quality. The circular or elliptical guide rail cross-section design also avoids jamming and wear caused by excessive local friction. Referring to Figure 7, the drive assembly 90 also includes a drive component 24 and a transmission structure 25. The transmission structure 25 is connected to the output end of the drive component 24 and is also connected to the slider 22. The drive component 24 serves as the power source.

[0093] This transmission structure design efficiently and stably transmits the power of the drive component to the slider, improving the load-bearing capacity and operating efficiency of the housing assembly. Using a motor as the drive component, in conjunction with a rack and pinion transmission structure, ensures a stable and powerful driving force for the door assembly or material-bearing component. This design not only improves the load-bearing capacity and operating efficiency of the housing assembly but also ensures the continuity and reliability of the material discharge process, reducing equipment failures caused by insufficient driving force or unstable transmission.

[0094] As shown in Figure 7, the driving component 24 is a motor, and the transmission structure 25 includes a gear 251 and a rack 252. The gear 251 meshes with the rack 252, the gear 251 is connected to the output end of the motor, and the rack 252 is connected to the slider 22. The extending direction of the rack 252 is parallel to the axial direction of the guide rail 21.

[0095] In another alternative embodiment, the drive element 24 can be a cylinder, which would eliminate the need for a gear and rack transmission mechanism.

[0096] Furthermore, a telescopic protective sleeve is fitted onto the outer side of the guide rail 21. This telescopic protective sleeve is elastically designed so that it can deform as the slider 22 slides relative to the guide rail 21. The telescopic protective sleeve can be a bellows-like device. Optical axis guide rails are convenient for adding bellows-like telescopic protective sleeves to prevent oil fumes from accumulating on the guide rail surface.

[0097] The housing 10 includes a first seat and a second seat disposed opposite to each other. The first seat is connected to a first end of the slider 22 along its length and the first seat is connected to a second end of the slider 22 along its length. The telescopic protective sleeve includes a first protective sleeve and a second protective sleeve. The two ends of the first protective sleeve are respectively connected to the first seat and the first end, and the two ends of the second protective sleeve are respectively connected to the second seat and the second end.

[0098] Optionally, the telescopic protective sleeve can also be configured as a single one. When there is only one telescopic protective sleeve, it is located between the first seat and the first end, or between the second seat and the second end.

[0099] During the sliding process of slider 22 relative to guide rail 21, the deformation directions of the first protective sleeve and the second protective sleeve are opposite. This arrangement ensures that throughout the entire stroke of slider 22, the first and second protective sleeves work together to protect the guide rail from being exposed to the working environment.

[0100] Furthermore, the housing assembly also includes a second link 60. One end of the second link 60 is connected to the rotating shaft 20, and the other end of the second link 60 is connected to the door body 30, so that when the rotating shaft 20 rotates about its own axis, it drives the door body 30 to move relative to the housing 10.

[0101] In an optional embodiment, the housing assembly may operate as follows: the slider 22 moves on the guide rail 21, thereby pushing the door 30 to open outward. At this time, the rotation of the door relative to the housing is transmitted to the rotating shaft 20 through the second connecting rod 60. The rotating shaft 20 rotates around its own central axis, thereby driving the second end of the first connecting rod 40 to rotate, ultimately causing the relative positional relationship between the first connecting rod 40 and the elastic element 50 to change. When the door is in different positions (such as the dead point position and the extreme position), it corresponds to different relative positional relationships between the first connecting rod 40 and the elastic element 50, thereby achieving the technical effect of assisting when the torque and the direction of door movement are in the same direction and supporting when they are in opposite directions.

[0102] In another alternative embodiment, the door has a handle, which the user can use to open the door 30 or push the door 30 back to the closed position.

[0103] Furthermore, the second link 60 has an arc-shaped structure and is recessed towards the door body 30.

[0104] The arc-shaped second link 60 guides the door 30 to move along a smooth arc trajectory when opening and closing, rather than a straight line or a complex curve. This not only makes the movement of the door 30 smoother, but also reduces collisions and friction between the door 30 and the housing 10 or other internal components, extending the service life of the equipment.

[0105] The arc-shaped design of the second link 60 and its recessed setting towards the door 30 allow it to fit more tightly into the internal structure of the housing 10 when the door 30 is closed, reducing the space occupied, making the internal layout of the equipment more compact, the external size smaller, and making it easier to use in limited spaces.

[0106] Furthermore, the elastic element 50 is a pneumatic spring. The pneumatic spring is preferably a nitrogen spring.

[0107] Furthermore, the housing assembly also includes an elastic element mounting base 70, which is connected to the housing 10, and the second end of the elastic element 50 is rotatably connected to the elastic element mounting base 70.

[0108] Furthermore, the housing assembly also includes a partition 80, which divides the cavity into at least a material box cavity 111 and a drive cavity 112. The second connecting rod 60 is located in the material box cavity 111, the rotating shaft 20 passes through the mounting hole on the partition 80, and the first connecting rod 40 and the elastic element 50 are both located in the drive cavity 112.

[0109] The internal space is divided by the partition 80, which realizes the rational layout of functional components. The material box cavity 111 is used to place the items to be processed, while the drive cavity 112 is used to accommodate mechanical and power components such as the drive assembly 90, the rotating shaft 20, the first connecting rod 40, and the elastic element 50. This separate design helps each component to operate independently, reduces mutual interference, and improves the overall efficiency and stability of the system.

[0110] The partition 80 not only achieves functional zoning but also optimizes the utilization of internal space. The material box cavity 111 and the drive cavity 112 occupy the optimal positions of the housing 10, ensuring maximum material storage space while also guaranteeing the rational layout of the drive assembly and other mechanical components.

[0111] By placing the drive assembly 90 and mechanical parts inside the drive cavity 112, grease, dry materials, etc., can be prevented from directly contacting these parts from the material box cavity 111, reducing the difficulty of cleaning and maintenance.

[0112] Furthermore, the length direction of the first connecting rod 40 is perpendicular to the axial direction of the rotating shaft 20, and / or the length direction of the elastic element 50 is perpendicular to the axial direction of the rotating shaft 20.

[0113] Furthermore, when the door 30 is in the dead position, the angle between the door 30 and the vertical plane is A1, where 25°≥A1≥15°.

[0114] Furthermore, when the door 30 is in the closed position, the door 30 is parallel to the vertical plane, and / or, when the door 30 is in the extreme position, the door 30 is perpendicular to the vertical plane.

[0115] According to one aspect of this utility model, a kitchen appliance is provided, including a housing assembly, which is the housing assembly described above. The kitchen appliance can be a dispensing appliance or a cooking appliance.

[0116] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0117] (1) The door opening and closing has a good assisted feel. During the opening process, the nitrogen spring can automatically open the door after passing the dead point of the rod system; during the closing process, the nitrogen spring can automatically close the door after passing the dead point of the rod system.

[0118] (2) Add a flexible limiting post when the door is opened to the limit position to ensure that the nitrogen spring is in a slightly compressed state, which can eliminate the door's wobbling and give users a better product experience.

[0119] (3) The opening and closing force of the door can be quickly adjusted according to the force of the nitrogen spring;

[0120] (4) When the door is closed, the nitrogen spring provides a clockwise torque, which makes the door press the seal, thus forming a better sealing effect.

[0121] (5) The nitrogen spring solution is connected by a rod system and hidden on the left and right sides of the dry material bin, making the dry material bin more aesthetically pleasing when opened.

[0122] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0123] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application.

Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.

[0124] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0125] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
