Description
Technical Field
[0001] This invention relates to the field of oven technology, and in particular to an oven with an automatic door opening mechanism. Background Technology
[0002] Ovens are a common household appliance used for baking food. Because the high temperatures inside an oven can cause the door to become very hot, there is a risk of burns if the user touches it. To address this, some ovens with automatic door opening mechanisms have been introduced to the market. For example, Chinese utility model patent CN216893935U discloses a pre-compression door hinge that enables automatic door opening. Its corresponding opening mechanism continuously applies force to the door in the opening direction, and when the door is unlocked, it automatically opens to a certain angle under the action of the opening mechanism. However, most existing ovens still require manual operation of the door lock, which requires considerable force to open, undoubtedly reducing the user experience. Summary of the Invention
[0003] This invention provides an oven with an automatic door opening mechanism. Users can operate the corresponding door opening button to automatically open the door, thus improving the user experience.
[0004] To solve the above problems, the present invention adopts the following technical solution:
[0005] An embodiment of the present invention provides an oven with an automatic door opening mechanism, including an oven body, a door, an opening mechanism, an opening button, a locking device, and a controller. One end of the door is rotatably connected to the oven body, and the other end is provided with a latch adapted to the locking device. The opening mechanism is disposed on the oven body and connected to the door, and is used to apply a force to the door to rotate it in the opening direction. The opening button and the controller are both disposed on the oven body or the door, and the locking device is disposed on the oven body. Both the opening button and the locking device are connected to the controller. When the door is in the closed state, the locking device engages with the latch to keep the door closed. After the door is in the closed state, when the opening button is triggered by the user, the controller controls the locking device to disengage from the latch, and the door automatically opens to a preset angle under the action of the opening mechanism.
[0006] In some embodiments, the oven body or door is further provided with a wireless communication module, which is connected to the controller; when the door is in the closed state, when the controller receives a preset door opening command through the wireless communication module, the controller controls the locking device to disengage, and the door automatically opens to a preset angle under the action of the door opening mechanism.
[0007] In some embodiments, an operation panel is fixed on the oven body; the door opening button is a physical button set on the operation panel, or a touch screen is fixed on the operation panel, and the door opening button is a virtual button set on the touch screen.
[0008] In some embodiments, the door body includes a door panel, a door frame, and a light-transmitting observation panel. The door frame is fixed to the back side of the door panel, the door panel has a through opening, and the observation panel is fixed to the inside of the door frame and covers the opening. The fastener is a fastening groove provided on the door frame.
[0009] In some embodiments, the locking device includes a bracket, a driver, a transmission assembly, a pin, and an elastic mechanism; the pin includes a pin rod and a latch disposed on the pin rod, the pin rod is slidably connected to the bracket in a vertical direction and can slide relative to the bracket to a locking position and an unlocking position; when the pin rod is in the locking position, the latch engages with the latching position, and when the pin rod is in the unlocking position, the latch disengages from the latching position; the elastic mechanism is used to apply a force to the pin rod towards the locking position; the driver is fixed on the bracket, and the driver, transmission assembly, and pin rod are connected in sequence, the driver is connected to a controller, and is used to drive the pin rod to slide to the unlocking position through the transmission assembly.
[0010] In some embodiments, the transmission assembly includes a rotating disk and a transmission rod. The rotating disk is connected to a driver, which drives the rotating disk to rotate about its axial direction. The axial direction of the rotating disk is parallel to the sliding direction of the pin relative to the bracket. The unlocking position is located above the locking position. The transmission rod is located above the rotating disk and connected to the pin. The force applied by the elastic mechanism causes the transmission rod to abut against the top surface of the rotating disk. The top surface of the rotating disk has a protrusion with a guide slope. The guide slope extends circumferentially along the rotating disk, and its height gradually increases circumferentially. When the transmission rod moves to the highest point of the guide slope, the pin is in the unlocking position. When the transmission rod moves to the lowest point of the guide slope, the pin is in the locking position.
[0011] In some embodiments, the locking device further includes an angle detection mechanism connected to a controller. The angle detection mechanism is used to detect the rotation angle of the rotating disk. When the angle detection mechanism detects that the rotating disk has rotated to the unlocked position, the controller is used to control the driver to stop applying driving force to the transmission assembly. The transmission rod moves to the lowest point of the guide slope under the action of the elastic mechanism.
[0012] In some embodiments, the top surface of the rotating disk has a plurality of protrusions evenly distributed around the axis of the rotating disk. The protrusions also have reset slopes extending circumferentially along the rotating disk. The height of the reset slopes gradually decreases in the direction in which the height of the guide slopes gradually increases. The guide slopes and reset slopes are distributed at intervals and connected sequentially in the circumferential direction of the rotating disk, and the slope of the reset slopes is greater than the slope of the guide slopes. When the angle detection mechanism detects that the rotating disk has rotated to the unlocked position of the pin, the transmission rod moves along the reset slopes to the lowest point of the guide slopes under the action of the elastic mechanism.
[0013] In some embodiments, the angle detection mechanism includes a micro switch, and a boss is provided on the circumferential surface of the rotating disk. The micro switch is configured to be triggered by the boss when the rotating disk rotates to the unlocked position of the pin. When the micro switch is triggered, the controller controls the driver to stop applying driving force to the transmission assembly.
[0014] In some embodiments, multiple bosses are provided corresponding to the guide ramps. Whenever the transmission rod moves to the highest point of a guide ramp, the boss corresponding to that guide ramp can trigger a micro switch.
[0015] The present invention has at least the following beneficial effects: When the user needs to open the door, the user only needs to operate the door opening button on the oven body or the door. After the controller senses that the door opening button has been triggered, it sends a corresponding control signal to the locking device, causing the locking device to disengage and the door to be no longer locked. The force applied to the door by the door opening mechanism causes the door to open automatically to a preset angle, thereby realizing automatic door opening. Compared with the existing method, it is simpler and more convenient for the user to operate, and improves the user experience. Attached Figure Description

[0033] The present invention is provided below with reference to the accompanying drawings to aid in a full understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0034] In the description of this invention, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.
[0035] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0036] An embodiment of the present invention provides an oven with an automatic door opening mechanism, such as... Figure 1-4 As shown, the oven includes an oven body 10, a door 20, a door opening mechanism 30, a door opening button, a locking device 40, and a controller. The oven body 10 has a receiving cavity 11, in which food to be baked is placed, and the oven body 10 is used to bake the food. The receiving cavity 11 has an opening on the front side of the oven body 10 for the user to place or remove food. The door 20 is located on the front side of the oven body 10, with one end rotatably connected to the oven body 10. The door 20 switches between open and closed states by rotation. When closed, it seals the opening to keep the receiving cavity 11 warm; when open, the opening of the receiving cavity 11 is exposed, allowing the user to place or remove food. The other end of the door 20 has a latch 21 adapted to the locking device 40, allowing the locking device 40 to engage with the latch 21.
[0037] A door opening mechanism 30 is mounted on the oven body 10 and connected to the door 20. The door opening mechanism 30 applies a force to the door 20, causing it to rotate in the opening direction. Both the door opening button and the controller are located on the oven body 10 or the door 20. A locking device 40 is mounted on the oven body 10, and both the door opening button and the locking device 40 are connected to the controller. When the door 20 is closed, the locking device 40 engages with the latch 21, preventing the door 20 from opening and keeping it closed. When the door 20 is closed, the user can operate the opening button by touching, pressing, tapping, or other means to open the door. The controller will sense that the opening button has been triggered and send a corresponding control signal to the latching device 40, causing the latching device 40 to disengage from the latch position 21. The door 20 is no longer locked, and the force applied by the opening mechanism 30 to the door 20 causes the door 20 to open automatically to a preset angle, thus realizing automatic opening. Compared with the existing method, it is simpler and more convenient for users to operate, improving the user experience.
[0038] In some embodiments, the oven body 10 or the door 20 is further equipped with a wireless communication module. This module is connected to a controller, which can communicate with external terminal devices such as mobile phones via the wireless communication module. When the door 20 is closed, the user can operate the terminal device to issue a corresponding opening command. When the controller receives the preset opening command via the wireless communication module, it controls the latch device 40 to disengage from the latch position 21. The door 20 then automatically opens to a preset angle under the action of the opening mechanism 30, achieving automatic opening. This allows the user to control the door 20 without being near the oven, providing various opening operation methods and further enhancing the user experience. The wireless communication module includes, but is not limited to, WiFi, Bluetooth, 4G, and 5G modules.
[0039] In some embodiments, an operation panel 50 is fixed on the oven body 10, and the door opening button is a physical button located on the operation panel 50. The user can press the door opening button. Since the operation panel 50 is on the oven body 10, it is minimally affected by the high temperature of the oven, and the door opening button will not get hot to the touch.
[0040] In other embodiments, a touch screen is fixed on the control panel 50, and the door opening button is a virtual button set on the touch screen. The touch screen can display information such as menus and the oven's operating status to provide human-machine interaction and make it more convenient for users.
[0041] In some embodiments, a box body 60 may be fixed on the oven body 10, the aforementioned operation panel 50 may be fixed on the surface of the box body 60, and the locking device 40 may be fixed inside the box body 60 to provide protection for the locking device 40.
[0042] In some embodiments, such as Figure 5 As shown, the door includes a door panel 22, a door frame 23, and a light-transmitting observation panel 24. The door frame 23 is fixed to the back of the door panel 22, and the door panel 22 has a through opening. The observation panel 24 is fixed to the inside of the door frame 23 and covers the opening on the door panel 22. Because the observation panel 24 is light-transmitting, the oven cavity can be observed through the observation panel 24 to understand the baking status of the food. The observation panel 24 can be made of a light-transmitting material such as glass.
[0043] The latch 21 is a latch groove set on the door frame 23. After the latching device is inserted into the latch groove, it can restrict the rotation of the door body to achieve the locking cooperation between the latching device and the latch. When the latching device is removed from the latch groove, the latching device no longer restricts the rotation of the door body, and the door body can automatically open to the preset angle under the action of the door opening mechanism.
[0044] In some embodiments, the door opening mechanism may be an existing door opening mechanism, the specific structure and working principle of which will not be described in detail.
[0045] In some embodiments, the driver may include a control chip such as a microcontroller.
[0046] In some embodiments, such as Figure 6-9 As shown, the locking device includes a bracket 100, a driver 200, a transmission assembly 300, a pin 400, and a resilient mechanism 500. The bracket 100 can be used to fix the driver 200, the transmission assembly 300, the pin 400, and the resilient mechanism 500 so that the driver 200, the transmission assembly 300, the pin 400, and the resilient mechanism 500 can be organically combined together, and the bracket 100 can be fixed to the oven body. The latch 400 includes a pin 410 and a latch 420 disposed on the pin 410. The pin 410 is slidably connected to the bracket 100 in the vertical direction, and the pin 410 can slide relative to the bracket 100 to a locked position and an unlocked position. When the pin 410 slides relative to the bracket 100 to the locked position, the latch 400 is in the locked state, and the latch 420 can be engaged in the latch position on the door to lock the door. When the pin 410 slides relative to the bracket 100 to the unlocked position, the latch 400 is in the unlocked state, and the latch 420 can disengage from the corresponding latch position to release the locking of the door. The elastic mechanism 500 is used to apply a force to the pin 410 toward the locked position so that the pin 410 can be held in the locked position. A certain external force is required to overcome the force of the elastic mechanism 500 so that the pin 410 can move toward the unlocked position. The driver 200 is fixed on the bracket 100, and the controller is connected to the driver 200. The controller can send control commands to the driver 200 to control the driver 200 to output driving force or stop outputting driving force. The driver 200, the transmission component 300, and the pin 410 are connected in sequence. When it is necessary to unlock the pin 400, the driver 200 transmits driving force through the transmission component 300, thereby driving the pin 410 to slide to the unlocked position. The entire pin 400 is then in the unlocked state, and the user does not need to manually apply force to the pin 400. Therefore, it is more labor-saving and convenient to use, which undoubtedly improves the user experience.
[0047] In some embodiments, the transmission assembly 300 includes a rotating disk 310 and a transmission rod 320. The rotating disk 310 is connected to a driver 200, which drives the rotating disk 310 to rotate about its axial direction. The axial direction of the rotating disk 310 is parallel to the sliding direction of the pin 410 relative to the bracket 100, thus the axial direction of the rotating disk 310 is parallel to the vertical direction. In the unlocked position, located above the latched position, the elastic mechanism 500 applies a downward force to the pin 410, causing the pin 410 to move downward towards the latched position. The transmission rod 320 is located above the rotating disk 310 and connected to the pin 410. The force applied by the elastic mechanism 500 to the pin 410 causes the transmission rod 320 to move downward, thus the transmission rod 320 abuts against the top surface of the rotating disk 310. During the rotation of the rotating disk 310, the transmission rod 320 can always abut against the top surface of the rotating disk 310. The top surface of the rotating disk 310 has a protrusion 311, which has a guide slope 312. The guide slope 312 extends circumferentially along the rotating disk 310, and its height gradually increases circumferentially. During the rotation of the rotating disk 310, the transmission rod 320 can move on the protrusion 311. When the transmission rod 320 moves to the highest point of the guide slope 312, the pin 410 is lifted upwards, and is in the unlocked position. When the transmission rod 320 moves to the lowest point of the guide slope 312, the pin 410 is lowered, and is in the locked position. In this embodiment, the protrusion structure on the top surface of the rotating disk 310 drives the transmission rod 320 to move vertically, thereby changing the position of the pin 410, allowing the pin 400 to switch between locked and unlocked states.
[0048] In this embodiment, the axial direction of the transmission rod 320 can be perpendicular to the vertical direction, and the circumferential surface of the transmission rod 320 is smoother and easier to slide on the guide slope 312, so that the rotation of the rotating disk 310 can smoothly switch the state of the pin 400.
[0049] Furthermore, the automatically unlockable latch structure of this embodiment also includes an angle detection mechanism 600. The angle detection mechanism 600 is connected to the controller and is used to detect the rotation angle of the rotating disk 310 and can send the detection result to the controller. The controller can issue corresponding control commands to the driver 200 so that the driver 200 can apply driving force to the pin 410 or stop generating driving force. It can be preset that when the rotating disk 310 rotates to a preset trigger angle, the transmission rod 320 moves to the highest point of the guide slope 312, and the pin 410 is in the unlocked position accordingly. Therefore, when the angle detection mechanism 600 detects that the rotating disk 310 has rotated to the preset trigger angle, the pin 410 is in the unlocked position. The controller controls the driver 200 to stop applying driving force to the transmission assembly 300. The pin 410 loses the driving force that allows it to overcome the elastic mechanism 500. Therefore, the force of the elastic mechanism 500 will drive the transmission rod 320 to move, which in turn drives the pin 410 to move. The transmission rod 320 will move to the lowest point of the guide slope 312, so that the pin 410 can be reset to the locking position for continued use of the pin 400.
[0050] Furthermore, the top surface of the rotating disk 310 has a plurality of protrusions 311 evenly distributed around its axis. Each protrusion 311 has a guide slope 312 and a reset slope 313 extending circumferentially along the rotating disk 310. The height of the reset slope 313 gradually decreases in the direction where the height of the guide slope 312 gradually increases. Therefore, in the circumferential direction of the rotating disk 310, the height of the protrusion 311 first gradually increases and then gradually decreases. The guide slopes 312 and reset slopes 313 are spaced apart and sequentially connected in the circumferential direction of the rotating disk 310. A reset slope 313 is provided between every two adjacent guide slopes 312, and each reset slope 313 is connected to its two adjacent guide slopes 312. Similarly, a guide slope 312 is provided between every two adjacent reset slopes 313, and each guide slope 312 is connected to its two adjacent reset slopes 313. When the rotating disk 310 rotates, the transmission rod 320 can slide on the guide slope 312 and the reset slope 313, thereby repeatedly moving the transmission rod 320 in the vertical direction. The slope of the reset slope 313 is greater than that of the guide slope 312. The distance required to move along the reset slope 313 to the lowest point of the guide slope 312 is less than the distance required to move along the guide slope 312 to the lowest point of the guide slope 312. Therefore, when the transmission rod 320 moves along the reset slope 313, it can move to the lowest point of the guide slope 312 more quickly. When the angle detection mechanism 600 detects that the rotating disk 310 has rotated to the unlocked position of the pin 410, the transmission rod 320 moves along the reset slope 313 to the lowest point of the guide slope 312 under the force of the elastic mechanism 500. This allows the pin 410 to quickly reset to the locking position. When the rotating disk 310 rotates in the same direction, the pin 410 can cycle between the unlocked and locking positions to ensure the stable operation of the entire mechanism.
[0051] Furthermore, the angle detection mechanism 600 includes a micro switch, and a boss 314 is provided on the circumferential surface of the rotating disk 310. The micro switch is configured to be triggered by the boss 314 when the rotating disk 310 rotates to the unlocked position of the pin 410. When the micro switch is triggered, it indicates that the pin 410 is in the unlocked position. After the controller senses that the micro switch has been triggered, its control driver 200 stops applying driving force to the transmission assembly 300. The force of the elastic mechanism 500 will drive the transmission rod 320 to move, which in turn drives the pin 410 to move. The transmission rod 320 will move to the lowest point of the guide slope 312, allowing the pin 410 to return to the locking position.
[0052] Furthermore, multiple bosses 314 are provided corresponding to the guide ramps 312. Whenever the transmission rod 320 moves to the highest point of a guide ramp 312, the bosses 314 corresponding to the guide ramp 312 can trigger the micro switch. In this way, there is no need to configure multiple micro switches, which can reduce the manufacturing cost of the entire latch structure.
[0053] In some embodiments, the driver 200 is a motor, and the rotating disk 310 is sleeved on the output shaft of the motor. When the output shaft of the motor rotates, the rotating disk 310 is driven to rotate accordingly.
[0054] In some embodiments, the bracket 100 includes an upper support plate 110, which has a through hole extending vertically through it. A pin 410 passes through the through hole and can slide along it, thereby achieving a vertically slidable connection between the pin 410 and the bracket 100. The pin 410 includes a support portion 411 located below the upper support plate 110 and protruding from the pin 410. The elastic mechanism 500 is a spring sleeved on the pin 410, with its two ends abutting against the top surfaces of the upper support plate 110 and the support portion 411, respectively. Since the upper support plate 110 is fixed in position, the elastic force applied by the spring causes the support portion 411 to move downwards, allowing the pin 410 to remain in a locked position. Because the spring is sleeved on the pin 410, it is not easily disengaged from the pin 410, thus providing a stable elastic force in the vertical direction.
[0055] Furthermore, the bracket 100 also includes a lower support plate 120 located below the upper support plate 110. The lower support plate 120 is provided with a square hole that penetrates it in the vertical direction. The cross-sectional shape of the support part 411 is set to be square to match the square hole. The support part 411 passes through the square hole and can slide along the square hole. Since the cross-sectional shape of the support part 411 is square, the support part 411 cannot rotate in the square hole, thereby providing a guiding effect on the entire pin 410, so that the pin 410 moves in the vertical direction but cannot rotate. The transmission rod 320 will not move out of the top surface of the rotating disk 310, so as to maintain the state of abutting against the top surface of the rotating disk 310.
[0056] In some embodiments, the snap fastener 420 is disposed at the lower end of the pin 410, and the transmission rod 320 is disposed at the upper end of the pin 410. The snap fastener 420 may be provided with a guide ramp 421 so that during the process of the snap fastener 400 being engaged, the snap fastener 400 can be pushed by the component abutting against the guide ramp 421, thereby moving upward by itself. When the snap fastener 400 is in the engaged position, the snap fastener 420 can be engaged in the engaged position under the action of the elastic mechanism 500.

5. The oven with an automatic door opening according to claim 1, characterized in that: The locking device also includes an angle detection mechanism, which is connected to the controller. The angle detection mechanism is used to detect the rotation angle of the rotating disk. When the angle detection mechanism detects that the rotating disk has rotated to the unlocked position, the controller is used to control the driver to stop applying driving force to the transmission assembly. The transmission rod moves to the lowest point of the guide slope under the action of the elastic mechanism.
6. The oven with an automatic door opening according to claim 5, characterized in that: The top surface of the rotating disk has a plurality of protrusions evenly distributed around the axis of the rotating disk. Each protrusion also has a reset slope extending circumferentially along the rotating disk. The height of the reset slope gradually decreases in the direction in which the height of the guide slope gradually increases. The guide slope and the reset slope are distributed at intervals and connected sequentially in the circumferential direction of the rotating disk, and the slope of the reset slope is greater than the slope of the guide slope. When the angle detection mechanism detects that the rotating disk has rotated to the unlocked position of the pin, the transmission rod moves along the reset slope to the lowest point of the guide slope under the action of the elastic mechanism.
