These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0046] As described in the background technology, the integrated stove of the related technology includes a steam-bake box, which has a box body and a box door. The user places the food to be cooked inside the box body. When the box body finishes cooking the food, the user pulls the handle on the box door to open the box door and take out the cooked food.

[0047] However, when the steam-bake oven finishes cooking, the temperature inside the steam-bake oven is high. When the user opens the oven door, the steam inside the steam-bake oven rushes towards the user, which may cause burns to the user's hands and may even cause serious damage to the user's face.

[0048] In response to the above technical problems, the embodiments of the present application provide an automatic door opening structure and cooking equipment. When the cabinet door needs to be opened, the cam is driven to rotate by a motor. When the raised portion of the cam abuts against the lock tongue, the cam can drive the lock tongue to move into the limiting groove. At this time, the cabinet door is in a state of closing the cabinet. When the raised portion of the cam is out of abutment with the lock tongue, the lock tongue remains in abutment with the cam due to the elastic force of the elastic member, so that the elastic member drives the lock tongue to move out of the limiting groove. At this time, the cabinet door is in a state of opening the cabinet. At the same time, the driving component can drive the cabinet door to move in a direction away from the cabinet, so that the cabinet door is automatically opened without the user manually pulling the cabinet door, thereby preventing the high-temperature steam in the cabinet from causing harm to the user.

[0049] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0050] Combination Figures 1 to 4 , an automatic door opening structure, comprising:

[0051] The locking tongue 100 and the opening and closing assembly 200 are used to connect with the box body 400 of the cooking device. The opening and closing assembly 200 is used to drive the locking tongue 100 to move into or out of the limiting groove 510 on the box door 500 of the cooking device, so as to drive the box door 500 to lock or open the box body 400;

[0052] The driving assembly 300 is used to be arranged between the box body 400 and the box door 500. The driving assembly 300 is configured to drive the box door 500 to move in a direction away from the box body 400 when the box door 500 opens the box body 400.

[0053] In this embodiment, the bottom edge of the box door 500 is hinged to the bottom wall edge of the box body 400; the opening and closing assembly 200 is arranged in the middle of the top edge of the box body 400, and the limiting groove 510 is arranged in the middle of the top edge of the box door 500; in other embodiments, the entire box door 500 can be moved closer to or away from the box body 400.

[0054] In this embodiment, the drive assembly 300 includes an electric hydraulic hinge, a spring-assisted hinge and a pneumatic strut; the electric hydraulic hinge has a built-in electric hydraulic system, and when the box door 500 opens the box body 400, the box door 500 will slowly pop open; the spring-assisted hinge uses the power of the spring to assist in opening the door, and when the box door 500 opens the box body 400, the spring releases energy to make the box door 500 pop open quickly; the pneumatic strut is similar to the pneumatic strut used in the tailgate of a car, and the box door 500 is automatically opened or closed by the pneumatic strut; the electric hydraulic hinge, spring-assisted hinge and pneumatic strut are existing technologies, and the specific structure will not be repeated in this embodiment.

[0055] In this embodiment, an opening and closing button can be set on the cooking device. By pressing the opening and closing button, the cabinet door 500 opens the cabinet body 400, and at the same time, the cabinet door 500 can be automatically opened; the opening and closing component 200, the driving component 300 and the timing function of the cooking device can also be electrically connected. When the preset cooking time of the cooking device ends, the cabinet door 500 automatically opens the cabinet body 400, so that the cabinet door 500 is automatically opened without the user pressing a button.

[0056] By adopting the above technical solution, when the food in the box body 400 is prepared, the lock tongue 100 is driven by the opening and closing component 200 to move out of the limiting groove 510. At this time, the box door 500 can open the box body 400. At the same time, the driving component 300 can drive the box door 500 away from the box body 400, so that the user does not need to pull the box door 500 to open the box body 400, thereby preventing the high-temperature steam in the box body 400 from causing harm to the user; by driving the lock tongue 100 to move in or out of the limiting groove 510, the structure is simple and it is convenient to fix the box door 500.

[0057] Combination Figures 5 to 8 The opening and closing assembly 200 includes a shell 210, a cam 220 and a driving member 230. The shell 210 is used to connect with the box body 400. The lock tongue 100 is penetrated and slidably connected to the shell 210. The cam 220 is rotatably set in the shell 210. The driving member 230 is used to drive the protrusion 221 of the cam 220 to abut or disengage from the abutment with the lock tongue 100, so that the lock tongue 100 moves out of or into the limiting groove 510.

[0058] In this embodiment, the shell 210 includes a base 211 and an upper cover 212, and a U-shaped rod 213 is provided on the upper cover 212 and on both sides of the upper cover 212, and a clamping block 214 is provided on the base 211 and on both sides of the base 211. By driving the upper cover 212 toward the base 211 to move the rod, the clamping block 214 is clamped in the U-shaped rod 213, so that the upper cover 212 is fixed on the base 211; when the base 211 and the upper cover 212 need to be separated, the U-shaped rod 213 is moved toward the two sides away from the upper cover 212, so that the clamping block 214 is disengaged from the U-shaped rod 213, thereby separating the base 211 and the upper cover 212.

[0059] In this embodiment, the cam 220 is elliptical and has two protrusions 221 ; an abutment block is provided on the edge of the lock tongue 100 located in the shell 210 , and the cam 220 abuts against the abutment block, and the cam 220 abuts against the lock tongue 100 through the abutment block.

[0060] In other embodiments, the cam 220 may also be configured to be circular, and a protrusion 221 may be separately provided on the circular cam 220 .

[0061] By adopting the above technical solution, when it is necessary to drive the lock tongue 100 to move into the limiting groove 510, the protrusion 221 of the cam 220 is driven by the driving member 230 to abut against the lock tongue 100. At this time, the protrusion 221 can drive the lock tongue 100 on the shell 210 to move outside the shell 210, so that the lock tongue 100 moves into the limiting groove 510; when it is necessary to drive the lock tongue 100 out of the limiting groove 510, the protrusion 221 of the cam 220 is driven by the driving member 230 to disengage from the abutment with the lock tongue 100. When the cam 220 is in contact with the lock tongue 100, the lock tongue 100 can be prevented from moving outside the limiting groove 510, thereby improving the fixing strength of the lock tongue 100 in the limiting groove 510.

[0062] Combination Figures 5 to 8 The driving member 230 includes a motor, which is used to drive the cam 220 to rotate, so as to drive the protrusion 221 to abut against or disengage from the locking tongue 100.

[0063] By adopting the above technical solution and the setting of the motor, the motor can drive the cam 220 to rotate, so that the cam 220 drives the protrusion 221 to abut against the lock tongue 100 when rotating, so that the protrusion 221 drives the lock tongue 100 to rise, and when the cam 220 drives the protrusion 221 to disengage from the abutment with the lock tongue 100 when rotating, the cam 220 can drive the lock tongue 100 to descend, so that the lock tongue 100 moves out of or into the limiting groove 510, and the motor drives the cam 220 to rotate continuously, so that the lock tongue 100 can be driven to drive the box door 500 to be fixed or detached from the box body 400, and the way in which the motor drives the cam 220 to rotate has very high precision, thereby accurately controlling the rising or falling distance of the lock tongue 100.

[0064] In other embodiments, the driving member 230 can be replaced by an electric cylinder, by directly connecting the lock tongue 100 to the driving end of the electric cylinder, so that the electric cylinder directly drives the lock tongue 100 to rise or fall, thereby allowing the lock tongue 100 to move out of or into the limiting groove 510.

[0065] Combination Figures 5 to 8 The motor is arranged outside the housing 210, and the driving shaft 231 of the motor is passed through and rotatably connected to the housing 210. A first sealing member 240 is arranged between the driving shaft 231 of the motor and the housing 210. The first sealing member 240 is used to seal the gap between the driving shaft 231 and the housing 210.

[0066] In this embodiment, the first sealing member 240 includes a sealing seat 241 and an elastic first sealing ring 242. The sealing seat 241 is arranged on the housing 210. The motor is detachably connected to the sealing seat 241 by bolts. The inner wall of the sealing seat 241 has multiple groups of sealing surfaces 244 protruding toward the drive shaft 231. The sealing surfaces 244 are used to abut against the drive shaft 231. The sealing seat 241 and the sealing surfaces 244 are used to seal the gap between the drive shaft 231 and the sealing seat 241. The first sealing ring 242 is arranged between the sealing seat 241 and the housing 210. The first sealing ring 242 is used to seal the gap between the sealing seat 241 and the housing 210.

[0067] By adopting the above technical solution and the setting of the first sealing member 240, the gap between the drive shaft 231 and the sealing seat 241 and the gap between the sealing seat 241 and the shell 210 can be sealed. When the box door 500 is opened, the high-temperature steam in the box body 400 can be blocked when it moves between the drive shaft 231 and the sealing seat 241 and between the sealing seat 241 and the shell 210, thereby preventing the high-temperature steam from entering the shell 210 along the gap between the drive shaft 231 and the sealing seat 241 and between the sealing seat 241 and the shell 210, thereby preventing the high-temperature steam from affecting the components in the shell 210, and indirectly extending the service life of the opening and closing assembly 200.

[0068] Combination Fig. 9 and Fig.10 The opening and closing assembly 200 further includes an elastic member 250 , one end of the elastic member 250 is connected to the inner wall of the housing 210 , and the other end of the elastic member 250 is connected to the locking tongue 100 . The elastic member 250 is used to keep the locking tongue 100 and the cam 220 in abutment with each other.

[0069] In this embodiment, the elastic member 250 is a spring, and two springs are provided, and the two springs are respectively arranged on both sides of the lock tongue 100; when the protrusion 221 of the cam 220 is out of contact with the lock tongue 100, the spring is in a compressed state; when the protrusion 221 of the cam 220 is in contact with the lock tongue 100, the spring is in a further compressed state, so that the lock tongue 100 can always be in contact with the cam 220 by relying on the elastic force of the spring.

[0070] In other embodiments, the number of elastic members 250 can be adaptively adjusted as needed, for example, four elastic members 250 can be provided.

[0071] By adopting the above technical solution and the setting of the elastic member 250, the lock tongue 100 can be abutted against the cam 220 by relying on the elastic force of the elastic member 250. When the protrusion 221 of the cam 220 abuts against or disengages from the lock tongue 100, the lock tongue 100 can always maintain an abutment state with the cam 220, so that the lock tongue 100 can be effectively reset, which indirectly improves the reset effect of the lock tongue 100.

[0072] Combination Fig. 9 and Fig.10 A positioning column 260 is provided on the inner wall of the housing 210 and the locking tongue 100 at a position where the end of the elastic member 250 is located, and the elastic member 250 is sleeved on the positioning column 260 .

[0073] In this embodiment, the positioning column 260 is hollow, the cross-section of the positioning column 260 is circular, and the spring is sleeved on the positioning column 260; one end of the spring can abut against the inner wall of the shell 210, or one end of the spring can be fixedly connected to the inner wall of the shell 210, and the other end of the spring can abut against the lock tongue 100, or the other end of the spring can be fixedly connected to the lock tongue 100.

[0074] By adopting the above technical solution and the setting of the positioning column 260, the elastic member 250 is sleeved on the positioning column 260, so that the positioning column 260 can have a positioning effect on the elastic member 250, preventing the elastic member 250 from tilting when the lock tongue 100 compresses the elastic member 250, thereby indirectly improving the effect of the elastic member 250 driving the lock tongue 100 to reset.

[0075] Combination Fig. 9 and Fig.10 A second sealing member 110 is provided on the lock tongue 100 along the circumference of the lock tongue 100. The second sealing member 110 is used to abut 3002 against the outer wall of the housing 210 or the edge of the door 500 when the lock tongue 100 moves out of or into the limiting groove 510.

[0076] In this embodiment, the second sealing member 110 is an elastic second sealing ring.

[0077] By adopting the above technical solution and the second sealing member 110, when the box door 500 opens the box body 400, the locking tongue 100 moves out of the limiting groove 510, and the locking tongue 100 can drive the second sealing member 110 to abut against the outer wall of the shell 210, so that the second sealing member 110 seals the gap between the locking tongue 100 and the shell 210, thereby preventing the high-temperature steam inside the box body 400 from moving along the gap between the locking tongue 100 and the shell 210 to the inside of the shell 210 when the box door 500 is opened, thereby preventing the high-temperature steam inside the box body 400 from moving along the gap between the locking tongue 100 and the shell 210 to the inside of the shell 210 ... This step prevents high-temperature steam from affecting the components in the shell 210, and further indirectly extends the service life of the opening and closing assembly 200; when the door 500 closes the box body 400, the lock tongue 100 moves into the limiting groove 510, and the lock tongue 100 can drive the second sealing member 110 to abut against the edge of the door 500, so that the second sealing member 110 seals the limiting groove 510, preventing the steam in the box body 400 from entering into the limiting groove 510 and accumulating, thereby preventing the accumulated water in the limiting groove 510 from affecting the lock tongue 100.

[0078] Combination Fig. 9 and Fig.10 A groove 120 is provided on the lock tongue 100 along the circumference of the lock tongue 100 , and the groove 120 is used to accommodate part of the second sealing member 110 .

[0079] By adopting the above technical solution and setting the groove 120, the groove 120 can play a positioning effect on the second seal 110, thereby preventing the second seal 110 from moving on the lock tongue 100 when the second seal 110 abuts against the shell 210, and the second seal 110 can be detachably connected to the lock tongue 100 through the setting of the groove 120, thereby facilitating the installation and disassembly of the second seal 110.

[0080] Combination Fig. 9 and Fig.10 An elastic protrusion 111 is provided on the surface of the second sealing member 110 facing the housing 210 along the circumference of the second sealing member 110 .

[0081] In this embodiment, two protrusions 111 are provided, and the two protrusions 111 are arranged in sequence in a direction away from the locking tongue 100 . The shape of the protrusion 111 can be adaptively selected as needed, for example, the cross section of the protrusion 111 is set to be a triangle.

[0082] By adopting the above technical solution, when the lock tongue 100 moves out of the limiting groove 510, the lock tongue 100 can drive the protrusion 111 on the second sealing member 110 to move toward the shell 210, so that the shell 210 compresses the elastic protrusion 111, thereby further improving the sealing effect between the lock tongue 100 and the shell 210.

[0083] An embodiment of the present application also provides a cooking device, including a body and an automatic door opening structure arranged on the body.

[0084] Among them, the specific structure of the automatic door opening structure has been described in detail in the above embodiments and will not be repeated here.

[0085] In this embodiment, the cooking device may be an integrated stove, a built-in oven, an oven, a microwave oven, a microwave oven, a steam-bake-in-one machine, a steam-bake-in-one box, or other cooking device having a box body 400 and a box door 500 .

[0086] In other embodiments, the cooking device may be replaced by other devices having a box body 400 and a door 500, such as a reaction device having a box body 400 and a door 500. When harmful gases are present in the reaction inside the box body 400 of the reaction device, the door 500 is opened automatically, thereby eliminating the need for the user to open the door 500, thereby preventing the harmful gases in the box body 400 from causing harm to the user.

[0087] When it is necessary to open the door 500, the cam 220 is driven to rotate by the motor. When the raised portion 221 of the cam 220 abuts against the lock tongue 100, the cam 220 can drive the lock tongue 100 to move into the limiting groove 510. At this time, the door 500 is in a state of closing the box body 400. When the raised portion 221 of the cam 220 is disengaged from the lock tongue 100, the lock tongue 100 maintains an abutment state with the cam 220 due to the elastic force of the elastic member 250, so that the elastic member 250 drives the lock tongue 100 to move out of the limiting groove 510. At this time, the door 500 is in a state of opening the box body 400. At the same time, the driving assembly 300 can drive the door 500 to move in a direction away from the box body 400, so that the door 500 is automatically opened without the user manually pulling the door 500, thereby preventing the high-temperature steam in the box body 400 from causing harm to the user.

[0088] Finally, it should be noted that those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. The present invention is intended to cover any variations, uses or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art not disclosed by the present invention, are not limited to the precise structure described above and shown in the drawings, and may be modified and changed in various ways without departing from the scope thereof.
