Description

Technical Field

[0001] The invention relates to the field of cooking utensils, and in particular to an opening and closing mechanism for a lid of an embedded electric pressure cooker. Background Art

[0002] An electric pressure cooker is a cooking appliance that converts electrical energy into internal energy. It uses the physical phenomenon that the boiling point of liquid increases under higher air pressure to apply pressure to the water, so that the water can reach a higher temperature without boiling, thereby speeding up the efficiency of stewing food. In existing split-type electric pressure cookers, the lid can be rotatably buckled on the pot body to achieve a sealed connection between the lid and the pot body. Electric pressure cookers are usually placed in the kitchen, and the space in the kitchen is small, and the electric pressure cooker occupies a large space. Therefore, the applicant has designed a built-in electric pressure cooker that can be installed in a cabinet to save space, but in this way, after cooking, the storage and placement of the lid becomes a major user pain point. Summary of the invention

[0003] The object of the present invention is to provide an opening and closing mechanism for a lid of an embedded electric pressure cooker to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] A lid opening and closing mechanism for an embedded electric pressure cooker, comprising:

[0006] The cabinet is provided with an accommodating inner cavity, one side of the accommodating inner cavity is provided with an opening, the opening is connected to the outside, the top wall of the accommodating inner cavity is provided with a mounting seat, and the mounting seat has a mounting through hole;

[0007] A support frame connected to the cabinet body, which can extend out along the opening or be retracted into the accommodating cavity;

[0008] A pot body, which is arranged on the support frame, and has an upward opening;

[0009] A pot cover, which is arranged in the accommodating inner cavity and is used to cover the opening;

[0010] A transmission member having a long slotted hole arranged obliquely;

[0011] A driving member, which is arranged on the cabinet and is used to drive the transmission member to move along a horizontal plane;

[0012] A connecting piece, which is connected to the pot cover, a protrusion is provided on the outer wall of the connecting piece, and the protrusion extends upward from the bottom end of the connecting piece. The connecting piece is provided with a linkage rod, and the linkage rod extends outward and extends into the long slot hole to realize the rotation of the connecting piece with the movement of the transmission piece. The connecting piece is arranged in the mounting through hole, and the mounting seat is provided with a stop protrusion located in the mounting through hole, and the stop protrusion cooperates with the protrusion to limit the rotation stroke of the connecting piece; when the protrusion of the transmission piece rotates to the stop protrusion, the connecting piece is driven to rise through the long slot hole.

[0013] The beneficial effect of the present invention is that the opening and closing actions of the pot cover and the opening of the pot body are all completed in the accommodating inner cavity of the cabinet, thereby avoiding the pot cover from occupying kitchen space.

[0014] As a further improvement of the above technical solution, the driving member and the transmission member are both arranged above the top wall.

[0015] The driving member and the transmission member are both arranged above the top wall of the accommodating inner cavity, so that the driving member and the transmission member are separated above the top wall. Since water vapor often emerges when the electric pressure cooker lid is opened after cooking, the top wall of the accommodating inner cavity separates the driving member from the lid, and the water vapor generated when the electric pressure cooker is working is blocked in the accommodating inner cavity to prevent the water vapor from corroding the driving member.

[0016] As a further improvement of the above technical solution, the embedded electric pressure cooker lid opening and closing mechanism also includes a guide seat, which is arranged on the top surface of the top wall, and a slide groove is provided on the guide seat, and the slide groove extends along the front and rear directions. A slider is provided on the transmission member, and the slider can be slidably arranged in the slide groove.

[0017] The guide seat is used to guide the movement of the transmission member, so that the forward and backward movement of the transmission member is more stable and accurate, which is helpful to accurately control the rotation and lifting of the linkage rod, so that the opening and closing action of the pot cover and the pot body opening is more accurate.

[0018] As a further improvement of the above technical solution, the shape of the slide groove is an "inverted L" shape, and the shape of the slider matches the shape of the slide groove.

[0019] The shape of the slide groove is an "inverted L" shape, and the shape of the slider matches the slide groove, so that the slide groove has a supporting effect on the slider, so that the slider can be snapped into the slide groove, and the connection between the slider and the slide groove is more stable.

[0020] As a further improvement of the above technical solution, the embedded electric pressure cooker lid opening and closing mechanism also includes a limiting structure, which connects the pot body and the support frame, and limits the freedom of translation and rotation of the pot body on the support frame.

[0021] The limiting structure limits the freedom of translation and rotation of the pot body on the support frame, thereby ensuring that when the support frame is retracted into the accommodating inner cavity, the pot body is located below the pot cover, so that the pot cover can accurately cover the opening of the pot body.

[0022] As a further improvement of the above technical solution, the limiting structure is detachably connected to the supporting frame.

[0023] The limiting structure is detachably connected to the support frame, and the pot body can be removed from the support frame, making the maintenance of the pot body more convenient.

[0024] As a further improvement of the above technical solution, the driving member also includes a motor and a gear, the output shaft of the motor is connected to the axis of the gear, the motor drives the gear to rotate, and the transmission member is provided with a rack, the rack extends in the front and rear directions, and the rack is meshed with the gear for transmission.

[0025] The motor drives the gear to rotate, and the gear meshes with the rack on the transmission member to transmit the transmission, so that the forward and backward movement of the transmission member is more precise, which helps to accurately control the rotation and lifting of the drive rod, making the opening and closing of the pot cover and the pot body opening more accurate.

[0026] As a further improvement of the above technical solution, the thickness of the mounting seat is smaller than the distance between the top of the protrusion and the top of the connecting member.

[0027] The thickness of the mounting seat is smaller than the distance between the top of the protrusion and the top of the connecting member. When the protrusion is located below the mounting seat, the connecting member can rotate in the mounting through hole.

[0028] As a further improvement of the above technical solution, the linkage rod is a round rod.

[0029] The linkage rod is a round rod, so that the contact surface between the linkage rod and the long slot hole is relatively smooth, which helps the linkage rod to slide in the long slot hole.

[0030] As a further improvement of the above technical solution, the bottom of the connecting piece is detachably connected to the top of the pot cover.

[0031] The bottom of the connecting piece is detachably connected to the top of the pot cover, so the pot cover is easy to clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Reference Figures 1 to 5 The lid opening and closing mechanism of the embedded electric pressure cooker of the present invention is implemented as follows:

[0044] The lid opening and closing mechanism of the embedded electric pressure cooker comprises a cabinet 100, a support frame 200, a pot body 300, a pot cover 400, a driving member 500, and a connecting member 600. An accommodating inner cavity 110 is provided inside the cabinet 100, and an opening 111 is provided on the front side of the accommodating inner cavity 110, and the opening 111 is communicated with the outside, and the support frame 200 can be extended or retracted into the accommodating inner cavity 110. The pot body 300 is arranged on the support frame 200, and an upward opening 310 is provided on the top of the pot body 300. The pot cover 400 is used to cover the opening 310 of the pot body 300, and the pot cover 400 and the pot body 300 rotate relative to each other so that the pot cover 400 and the opening 310 are buckled.

[0045] The transmission member 510 is provided with an obliquely arranged long slot hole 511. Figure 2 The long slot hole 511 is inclined so as to gradually rise from the front to the back.

[0046] The driving member 500 is disposed on the cabinet 100 and has a transmission member 510. The driving member 500 drives the transmission member 510 to move along a horizontal plane, and is used to drive the transmission member 510 to move along a horizontal plane. The moving direction of the transmission member 510 is a front-to-back direction.

[0047] A mounting seat 115 is disposed on the top wall 112 of the accommodating inner cavity 110 . The mounting seat 115 has a mounting through hole 113 . The inner wall of the mounting through hole 113 is provided with a stop protrusion 114 . The stop protrusion 114 is usually passed through in the up-down direction.

[0048] The connecting member 600 is arranged in the installation through hole 113, and the bottom of the connecting member 600 is connected to the pot cover 400. The outer wall of the connecting member 600 is provided with a linkage rod 620, which extends outward and extends into the long slot hole 511 of the transmission member 510, so that the connecting member 600 can rotate with the movement of the transmission member 510.

[0049] A protrusion 610 is provided on the outer wall of the connecting member 600; the cooperation between the stop protrusion 114 and the protrusion 610 is used to limit the rotation stroke of the connecting member 600; when the protrusion rotates to the stop protrusion 114, the transmission member 510 drives the connecting member 600 to rise through the long slot hole 511.

[0050] The support frame 200 is folded in the accommodating inner cavity 110 of the cabinet 100, and the pot cover 400 is covered on the open opening 310 of the pot body 300. The pot cover 400 is buckled with the pot body 300. At this time, the protrusion 610 on the connecting member 600 deviates from the stop protrusion 114; when the pot cover 400 and the pot body 300 need to be opened, the driving member 500 drives the transmission member 510 to move forward, and the long slot hole 511 of the transmission member 510 drives the linkage rod 620 to rotate counterclockwise around the installation through hole 113, and the connecting member 60 0 rotates counterclockwise in the installation through hole 113, causing the pot cover 400 to rotate counterclockwise, thereby loosening the engagement between the pot cover 400 and the pot body 300. At this time, the protrusion 610 just rotates to the stop protrusion 114. Due to the restriction of the stop protrusion 114, the connecting member 600 and the pot cover 400 cannot continue to rotate counterclockwise; and the transmission member 510 continues to move forward, driving the linkage rod 620 to rise upward along the inclined long slot hole 511, and then the protrusion 610 on the connecting member 600 rotates along the stop protrusion 114. 4 moves upward, so that the connecting member 600 moves upward in the installation through hole 113, thereby driving the pot cover 40 to be separated from the opening 310 of the pot body 300, and the pot cover 400 is opened; at this time, when the pot cover 400 needs to be buckled with the pot body 300, the driving member 500 drives the transmission member 510 to move backward, and the transmission member 510 has no driving force on the linkage rod 620. The linkage rod 620 moves downward along the inclined long slot hole 511 under the action of gravity, so that the connecting member 600 is in the installation through hole The connecting member 600 moves downward in the mounting through hole 113, thereby driving the pot cover 400 to approach the pot body 300. When the pot cover 400 is closed on the opening 310 of the pot body 300, the connecting member 600 can no longer move downward, while the transmission member 510 continues to move backward. The long slot hole 511 of the transmission member 510 drives the linkage rod 620 to rotate clockwise, and the connecting member 600 rotates clockwise in the mounting through hole 113, causing the pot cover 400 to rotate clockwise relative to the pot body 300, thereby making the pot cover 400 buckle with the pot body 300.

[0051] It can be seen that the transmission member 510 moves and drives the connecting member 600 to realize the opening and closing of the pot cover 400 and the opening 310 .

[0052] The pot body 300 can be a pot body of a conventional electric pressure cooker, and the pot body 300 has a heating device, a power module, etc. in an electric pressure cooker, and the pot body 300 has inner and outer pots, pot teeth for connecting the pot cover, etc., that is, the pot body 300 has the functions and structures that the pot body of a split electric pressure cooker should have, and the pot body 300 is a pot body of an electric pressure cooker well known to those skilled in the art. Of course, the pot body 300 can be used as a pot body of an electric rice cooker, and those skilled in the art can achieve a simple replacement of an electric pressure cooker with an electric rice cooker without any intellectual creation.

[0053] There are many structures for realizing the buckling of the pot body 300 and the pot cover 400. For example, a pot tooth is provided on the top outer wall edge of the pot body 300. There are multiple pot teeth, all of which are arranged at intervals. A buckle position matching the pot teeth is provided on the inner wall of the pot cover 400. There are multiple buckle positions, all of which are arranged at intervals in sequence. The buckle position is "L" shaped, and the buckle position has a vertical part and a horizontal part. When the pot cover 400 is covered on the open mouth 310 of the pot body 300, the buckle position is staggered with the pot teeth. The pot cover 400 is rotated clockwise to push the horizontal part of the buckle position to rotate below the pot teeth, so that the water at the buckle position is The flat part rotates relative to the pot teeth, and when the pot teeth and the buckle position are buckled into place, the pot teeth and the vertical part of the buckle position abut against each other, so that the pot cover 400 and the pot body 300 are buckled together; when the pot cover 400 and the pot body 300 need to be opened, the pot cover 400 rotates counterclockwise, so that the horizontal part of the buckle position and the pot teeth rotate relative to each other, and then the horizontal part of the buckle position is separated from the bottom of the pot teeth. When the pot teeth are separated from the buckle position, the vertical part of the other buckle position abuts against the pot teeth, thereby limiting the pot teeth from continuing to rotate. At this time, the pot teeth and the buckle position are completely separated, so that the pot cover 400 and the pot body 300 are loosened.

[0054] In order to increase the rotation angle of the linkage rod 620 around the installation through hole 113, the diameter of the linkage rod 620 should be smaller than the width of the long slot hole 511, and the linkage rod 620 can pass through the long slot hole 511. When the long slot hole 511 drives the linkage rod 620 to move, the inner wall of one side of the long slot hole 511 abuts against the linkage rod 620, and a large margin is left between the inner wall of the other side of the long slot hole 511 and the linkage rod 620. As the rotation angle of the linkage rod 620 around the installation through hole 113 gradually increases, the distance between the linkage rod 620 and the inner wall of the other side of the long slot hole 511 gradually decreases, so that the movement margin of the linkage rod 620 in the long slot hole 511 gradually decreases. In order to make the linkage rod 620 move more smoothly in the long slot hole 511, the linkage rod 620 is set as a round rod, so that the contact surface between the linkage rod 620 and the inner wall of the long slot hole 511 is a circular arc surface.

[0055] In some embodiments, the driving member 500 and the transmission member 510 are both disposed above the top wall 112, so that the driving member 500 and the transmission member 510 are separated above the top wall 112. Then the top of the connecting member 600 passes through the installation through hole 113 and extends above the top wall 112. The linkage rod 620 is disposed above the top wall 112, and the bottom of the connecting member 600 passes through the installation through hole 113 and extends below the top wall 112, and the bottom of the connecting member 600 is connected to the pot cover 400. Then the top wall 112 separates the driving member 500 and the transmission member 510 outside the accommodating inner cavity 110. Since water vapor is generated when the electric pressure cooker is working, the water vapor is blocked in the accommodating inner cavity 110 to prevent the water vapor from corroding the driving member 500 and the transmission member 510.

[0056] In some embodiments, a guide seat 700 is provided on the top surface of the top wall 112, and the guide seat 700 is located between the mounting through hole 113 and the driving member 500. The guide seat 700 is provided with a slide groove 710, and the slide groove 710 extends in the front-to-back direction. The transmission member 510 is provided with a slider 512, and the slider 512 cooperates with the slide groove 710, and the slider 512 can move forward and backward along the slide groove 710. The slide groove 710 is used to guide the forward and backward movement of the slider 512, so that the forward and backward movement of the transmission member 510 is more stable and accurate.

[0057] In some embodiments, the slider 512 of the transmission member 510 is disposed in the slide groove 710, so that the rack 513 is kept in meshing state with the gear 502. The shape of the slide groove 710 is an "inverted L" shape, and the shape of the slider 512 matches the shape of the slide groove 710, so that the slide groove 710 forms a supporting force on the slider 512, so that the slider 512 is engaged in the slide groove 710, and the slider 512 can be prevented from falling out of the slide groove 710.

[0058] In some embodiments, a limiting structure 800 is provided between the support frame 200 and the pot body 300, and the limiting structure 800 limits the freedom of translation and rotation of the pot body 300 on the support frame 200. There are many types of limiting structures 800, for example, the limiting structure 800 is a bracket, and the limiting structure 800 is connected to the pot body 300 and the support frame 200 respectively; or, the limiting structure 800 is a screw, and a plurality of screws pass through the bottom wall of the support frame 200 and are screwed into the pot body 300; or, the limiting structure 800 is a groove on the bottom wall of the support frame 200, and the shape of the groove matches the bottom shape of the pot body 300, and the bottom of the pot body 300 is embedded in the groove. In this embodiment, the limiting structure 800 and the support frame 200 are detachably connected.

[0059] In some embodiments, the driving member 500 includes a motor 501 and a gear 502. The output shaft of the motor 501 is connected to the rotation axis of the gear 502, and the output shaft of the motor 501 drives the gear 502 to rotate. A rack 513 is provided on the transmission member 510, and the rack 513 extends in the front-to-back direction. The rack 513 is in transmission engagement with the gear 502, and the output shaft of the motor 501 drives the gear 502 to rotate, and the gear 502 drives the rack 513 to move forward and backward, thereby causing the transmission member 510 to move forward and backward.

[0060] In some embodiments, the thickness of the mounting seat 115 is smaller than the distance between the top of the protrusion 610 and the top of the connector 600. If the protrusion 610 on the connector 600 moves downward along the stop protrusion 114 and disengages from the stop protrusion 114, the distance between the top of the protrusion 610 and the top of the connector 600 is larger than the thickness of the mounting seat 115, so that the connector 600 can rotate in the mounting through hole 113 of the mounting seat 115.

[0061] In some embodiments, the bottom of the connecting member 600 is detachably connected to the top of the pot cover 400, so that the pot cover 400 can be removed from the connecting member 600, making it easier to clean the pot cover 400. There are many ways to connect the bottom of the connecting piece 600 to the top of the pot cover 400. For example, a screw is used to pass through the bottom of the pot cover 400 and then screwed into the bottom of the connecting piece 600; or, a buckle position is provided at the top of the pot cover 400, and a buckle is provided at the bottom of the connecting piece 600, the buckle cooperates with the buckle position, and the buckle at the bottom of the connecting piece 600 is inserted into the buckle position, so that the pot cover 400 and the connecting piece 600 are snap-connected; or, an upwardly protruding connecting column is provided at the top of the pot cover 400, a latch hole is provided on the outer wall of the connecting column, a blind hole matching the connecting column is provided at the bottom of the connecting piece 600, a through hole is provided on the outer wall of the bottom of the connecting piece 600, the through hole is connected to the blind hole, the connecting column is inserted into the blind hole, and a latch is inserted into the latch hole of the connecting column after passing through the through hole to form a latch connection.
