Description

Technical Field

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

[0002] With the development of modern kitchen appliances, ovens, as essential cooking equipment, have seen continuous optimization in terms of functionality and user experience. Traditional oven doors typically employ a hinge structure, relying on elastic components (such as springs) to open, close, and stop the door. While this design meets basic user needs to some extent, it still has several shortcomings in practical use. First, the elastic components are temperature-sensitive and easily lose their elasticity at high temperatures, leading to a decrease in damping effect. Second, the elastic components are prone to aging after long-term use, affecting their durability and performance. Furthermore, the adjustment range of elastic damping is limited, making it difficult to adapt to different scenarios. As the weight of oven doors increases, the load-bearing capacity of traditional hinges also faces challenges. More importantly, current door-stopping solutions mainly rely on manual operation, failing to meet the needs of intelligent operation, especially in high-temperature environments where steam escape when the door is opened may pose a safety hazard. Utility Model Content

[0003] Addressing the issues of poor elastic damping effect, easy failure, limited load-bearing capacity, and inability to meet intelligent requirements in existing technologies, this utility model provides a cooking device with a door suspension structure using a hydraulic locking method. This device features a simple structure, stable and reliable suspension function, strong load-bearing capacity, and intelligent control of door opening, thereby improving ease of use and safety.

[0004] This utility model provides a cooking device, including a housing, a door hinged to the housing via a pivot, and a door-hinging structure, the door-hinging structure comprising:

[0005] A drive mechanism, connected to the rotating shaft, is used to drive the door to rotate to any angle;

[0006] A locking mechanism for locking the door after it has been rotated to the desired angle, comprising:

[0007] A sleeve with an internal cavity;

[0008] The piston is located inside the cavity of the sleeve;

[0009] A control lever passes through the sleeve, with one end connected to the piston and the other end connected to the drive mechanism, which drives the control lever to move linearly.

[0010] A connecting pipe that connects the portion of the sleeve cavity located on both sides of the piston;

[0011] A liquid medium is filled inside the sleeve cavity and the connecting pipe;

[0012] A control valve, installed on the connecting pipe, is used to control the flow of the liquid medium;

[0013] A control system is used to control the movement of the drive mechanism and the opening and closing of the control valve.

[0014] In some embodiments, the drive mechanism includes:

[0015] A gear and rack mechanism includes a meshing gear and a rack, wherein the rack is connected to the control lever and the gear is connected to the rotating shaft;

[0016] A drive component for driving the gear to rotate.

[0017] In some embodiments, the rack and the control lever are an integral structure.

[0018] In some embodiments, the driving component is a motor, an electromagnetic component, a hydraulic component, or a pneumatic component.

[0019] In some embodiments, a seal is provided between the sleeve and the control rod.

[0020] In some embodiments, the control valve is a solenoid valve.

[0021] In some embodiments, the door suspension structure further includes a sensor for detecting the angular position of the door.

[0022] In some embodiments, the liquid medium is hydraulic oil or water.

[0023] In some embodiments, the door suspension structure further includes a reset mechanism for assisting the door in remaining in the locked position.

[0024] In some embodiments, the reset mechanism is a gas spring or a mechanical spring.

[0025] Compared with the prior art, the advantages and positive effects of this utility model are:

[0026] The aforementioned cooking equipment features a door-hovering structure that drives the door to rotate to any angle via a drive mechanism and locks it after the door has rotated to the desired angle using a locking mechanism, thus enabling the door 200 to hover at any position.

[0027] The door's suspension structure employs a hydraulic locking method. Compared to traditional elastic damping solutions, this structure is less sensitive to temperature changes and can adapt to long-term high-temperature operating environments, ensuring stable suspension performance even under the high-temperature operating conditions of the oven. Secondly, the suspension function of this structure is stable and reliable, with stronger fatigue resistance, meeting the needs of long-term, high-frequency use. Furthermore, the hydraulic locking method provides a wider damping adjustment range, allowing flexible adjustment of the damping force according to actual usage requirements, while also possessing stronger load-bearing capacity, capable of withstanding heavier door loads, adapting to the increasing weight of modern oven doors. In addition, through intelligent control, users do not need to manually operate the door, avoiding potential safety hazards caused by steam escape when the door is opened in high-temperature environments, while improving both convenience and safety.

[0043] Reference Figures 1-4 This is one embodiment of the cooking equipment of this utility model. The cooking equipment can be an oven, microwave oven, steam oven, microwave oven, microwave-steam-grill combination machine, etc.

[0044] The cooking equipment includes a housing 100, a door 200 hinged to the housing 100 via a pivot 210, and a door suspension structure 300.

[0045] The door-hovering structure 300 allows the door 200 to open at any angle and remain in that position. For example... Figure 3 As shown, the door suspension structure 300 specifically includes a drive mechanism 310, a locking mechanism 320, and a control system.

[0046] The drive mechanism 310 is connected to the rotating shaft 210 and is used to drive the door 200 to rotate to any angle. The locking mechanism 320 is used to lock the door 200 after it has rotated to the desired angle. The control system is used to control the actions of the drive mechanism 310 and the locking mechanism 320.

[0047] Specifically, the locking mechanism 320 includes a sleeve 321, a piston 322, a control rod 323, a connecting pipe 324, a liquid medium (not shown), and a control valve 325.

[0048] The sleeve 321 has a cavity. The piston 322 is located inside the cavity of the sleeve 321.

[0049] The control lever 323 passes through the sleeve 321, with one end connected to the piston 322 and the other end connected to the drive mechanism 310. The drive mechanism 310 drives the control lever 323 to move linearly.

[0050] The connecting pipe 324 connects to the cavity of the sleeve 321 located on both sides of the piston 322.

[0051] The liquid medium fills the cavity of sleeve 321 and the connecting pipe 324. The liquid medium can be hydraulic oil or water.

[0052] The control valve 325 is installed on the connecting pipe 324 and is used to control the flow of liquid medium.

[0053] The control system controls the movement of the drive mechanism 310 and the opening and closing of the control valve 325.

[0054] The working principle of the door suspension structure 300 is as follows:

[0055] Door opening: The user specifies the rotation angle of the door 200, and the control system controls the drive mechanism 310 to operate. The drive mechanism 310 drives the door 200 to rotate and open, and simultaneously drives the control lever 323 to move linearly. The control lever 323 pushes the piston 322 to move within the sleeve 321. When the control lever 323 moves, the control system controls the control valve 325 to open, allowing the liquid medium to flow through the connecting pipe 324.

[0056] The drive motor drives the gear 311 to rotate, and the gear 311 drives the rack 312 to move linearly, thereby driving the control lever 323 to move linearly. The control lever 323 pushes the piston 322 to move within the sleeve 321. When the control lever 323 moves, the control valve 325 opens, and the liquid medium flows through the connecting pipe 324, causing the door body 200 to rotate accordingly.

[0057] Door suspension: When the door 200 rotates to the desired angle, the control system controls the drive mechanism 310 to stop moving, and at the same time controls the control valve 325 to close, the liquid medium stops flowing, the piston 322 is locked in the sleeve 321, thereby stopping the control rod 323 from moving, and the door 200 stops rotating and remains at that angle.

[0058] Door closing: When the user inputs the door closing command, the control system controls the drive mechanism 310 to move and the control valve 325 to open. The drive mechanism 310 drives the control rod 323 to move in the opposite direction, and the piston 322 moves in the opposite direction in the sleeve 321. The liquid medium flows in the opposite direction through the connecting pipe 324. At this time, the control valve 325 is in the open state, and the door 200 closes accordingly.

[0059] In the aforementioned cooking equipment, the door suspension structure 300 drives the door 200 to rotate to any angle via the drive mechanism 310, and locks the door 200 after it has rotated to the required angle using the locking mechanism 320, thereby realizing the door 200's suspension function at any position.

[0060] The door suspension structure 300 employs a hydraulic locking mechanism. Compared to traditional elastic damping solutions, this structure is less sensitive to temperature changes and can adapt to long-term high-temperature operating environments, ensuring stable suspension performance even under high-temperature oven conditions. Secondly, the suspension function of this structure is stable and reliable, with stronger fatigue resistance, meeting the needs of long-term, high-frequency use. Furthermore, the hydraulic locking mechanism provides a wider damping adjustment range, allowing flexible adjustment of the damping force according to actual usage requirements, while also possessing stronger load-bearing capacity, capable of withstanding heavier door loads, adapting to the increasing weight of modern oven doors. In addition, through intelligent control, users do not need to manually operate the door 200, avoiding potential safety hazards caused by steam escape when the door 200 is opened in high-temperature environments, thus improving both convenience and safety.

[0061] In this embodiment, the drive mechanism 310 includes a gear and rack mechanism and a drive component.

[0062] The gear and rack mechanism includes a meshing gear 311 and a rack 312, wherein the rack 312 is connected to the control lever 323, and the gear 311 is fixedly connected to the rotating shaft 210.

[0063] The drive component is used to drive the gear 311 to rotate. The drive component can be a motor, an electromagnetic component, a hydraulic component, or a pneumatic component. Considering control accuracy and response speed, a linear motor (not shown in the figure) is preferred as the drive component. For applications requiring greater driving force, a hydraulic component or a pneumatic component can be selected.

[0064] This embodiment achieves precise angle control and rapid response of the door 200 by employing a rack and pinion mechanism and a motor as the drive mechanism 310. The rack and pinion mechanism has advantages such as high transmission efficiency and compact structure, and can effectively convert the rotational motion of the motor into the rotational motion of the door 200. The motor can precisely control the rotation angle and speed of the gear 311, thereby achieving precise control of the rotation angle and speed of the door 200.

[0065] When a rack and pinion mechanism and a linear motor are used as the drive mechanism 310, the control logic for the door 200 hovering is as follows: Figure 4 As shown, after the user specifies the rotation angle θ of the door 200, the control system controls the linear motor to start. The linear motor rotates the door 200 through the gear 311, and at the same time drives the control rod 323 to move linearly. When the control rod 323 moves, the control valve 325 opens. When the control rod 323 moves to a distance S, the control valve 325 closes and the control rod 323 stops moving, thereby achieving the suspension of the door 200 at any angle.

[0066] In some other embodiments, the drive mechanism 310 may also employ a lead screw and nut mechanism and a crank-connecting rod mechanism, with the control rod 323 connected to the lead screw, the nut hinged to the connecting rod in the crank-connecting rod mechanism, and the crank connected to the rotating shaft 210 of the door body 200 and driven to rotate by a motor.

[0067] In this embodiment, the rack 312 and the control lever 323 are made into an integral structure, and the rack 312 can be machined into one end surface of the control lever 323. The integral structure of the rack 312 and the control lever 323 simplifies the number of parts, reduces the number of connecting links, and improves transmission efficiency and reliability. The integral structure can avoid problems such as loosening or falling off between the rack 312 and the control lever 323, ensuring the stability and reliability of the drive mechanism 310.

[0068] In this embodiment, the sleeve 321 is fixed inside the housing 100, which ensures the stability of the locking mechanism 320. A seal 326 is provided between the sleeve 321 and the control rod 323 to prevent leakage of liquid medium inside the cavity. The seal is preferably a sealing ring.

[0069] In this embodiment, a solenoid valve is used as the control valve 325, which enables rapid and precise control of the liquid medium flow. The solenoid valve has advantages such as fast response speed and high control accuracy, ensuring that the gate 200 can lock in time when it reaches the preset angle.

[0070] In some other embodiments, the door hovering structure 300 may also include a sensor (not shown) for detecting the angular position of the door 200 and feeding the detection result back to the control system. The sensor may be an angle sensor, a Hall effect sensor, etc. By adding a sensor, real-time detection of the angular position of the door 200 can be achieved, thereby enabling more precise control of the door 200's hovering.

[0071] In this embodiment, the liquid medium is hydraulic oil or water. Hydraulic oil is preferred as the liquid medium because it has good lubricity and sealing properties, which can reduce friction between the piston 322 and the sleeve 321, improving the reliability of the locking mechanism 320. The reset mechanism can be a gas spring or a mechanical spring.

[0072] In some other embodiments, the door-hovering structure 300 also includes a reset mechanism (not shown) to assist the door 200 in remaining in the locked position, preventing the door 200 from moving due to external forces or other reasons. Adding a reset mechanism improves the stability of the door 200's hovering. The reset mechanism can provide an additional holding force to the door 200 when the control valve 325 is closed, preventing the door 200 from moving due to external forces or other reasons and ensuring that the door 200 always remains in the locked position.

[0073] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
