Technical Field

[0001] The invention relates to the field of cooking utensils, and in particular to an opening and closing device 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, which should save space, but in this case, 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 embedded electric pressure cooker lid opening and closing device 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:

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

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

[0010] A driving member is connected to the pot cover, and the driving member is used to drive the pot cover and the opening to open and close.

[0011] The beneficial effects of the present invention are as follows: the cabinet body can be arranged in a kitchen cabinet; since the pot body is arranged on the support frame, the support frame can be extended out or retracted into the accommodating inner cavity of the cabinet body, when the electric cooker needs to be used, the support frame can be pulled out, and the electric cooker can be stored in the accommodating inner cavity of the cabinet body when working, which is convenient to use, and the electric cooker does not need to occupy space on the stove; the pot cover is arranged in the accommodating inner cavity, and the pot cover and the pot body are driven to open and close by a driving member, and the opening and closing actions of the pot cover and the pot body are all completed in the accommodating inner cavity of the cabinet body, thereby effectively avoiding the pot cover from occupying kitchen space.

[0012] In some embodiments, the driving member is telescopically and rotatably arranged in the cabinet, and the driving member is provided with an operating part and a connecting part connected at an angle, the operating part is exposed outside the cabinet, and the connecting part is movably connected to the pot cover. The driving member drives the pot cover to rotate in the up and down directions during the telescopic process, and drives the pot cover to rise and fall in the up and down directions during the rotation process.

[0013] During the extension and retraction process, the driving member drives the pot cover to rotate in the up and down direction, and during the rotation process, the driving member drives the pot cover to rise and fall in the up and down direction, so that the pot cover performs lifting and rotating motion relative to the pot body, thereby realizing the opening and closing action of the pot cover and the pot body.

[0014] In some embodiments, a mounting hole is provided on the top wall of the accommodating inner cavity, a connecting piece is provided on the top of the pot cover, the connecting piece can movably pass through the mounting hole, the driving piece is located on the outside of the accommodating inner cavity, and the connecting part is movably connected to the connecting piece.

[0015] The connecting piece on the top of the pot cover can movably pass through the installation through hole on the top wall of the containing cavity, and the driving piece outside the containing cavity is connected to the connecting piece. The driving piece is separated outside the containing cavity, and the pot cover is located in the containing cavity. Most of the humid gas generated after the electric pressure cooker is cooked is intercepted in the containing cavity, which helps to keep the driving piece dry and prevent the driving piece from being corroded by the humid gas.

[0016] In some embodiments, the connecting member includes a rotating shaft and a support rod, the bottom end of the rotating shaft is connected to the pot cover, the rotating shaft is passed through the mounting through hole, the first end of the support rod is connected to the upper part of the rotating shaft, and the second end of the support rod is movably connected to the connecting part.

[0017] The connecting member is composed of a rotating shaft and a support rod. The rotating shaft cooperates with the mounting through hole to realize the rotation and up and down movement of the connecting member around the vertical axis in the mounting through hole. The connecting part of the driving member is movably connected to the second end of the support rod, so that the driving member has a clearance when driving the support rod to move, thereby avoiding the driving member and the support rod from getting stuck.

[0018] In some embodiments, the second end of the support rod is provided with a hinged through hole, the connecting part is provided with a connecting column, the connecting column can be movably inserted into the hinged through hole, and a limit block is provided at the end of the connecting column, which is used to limit the connecting column in the hinged through hole.

[0019] The connecting column of the driving member connecting part cooperates with the hinged through hole on the second end of the support rod, so that the connecting part of the driving member can drive the support rod to move. The limit block at the end of the connecting column prevents the hinged through hole from detaching from the connecting column. The structure of the movable connection between the connecting part and the support rod is simple and easy to produce.

[0020] In some embodiments, an elastic member is sleeved on the outer side of the rotating shaft, and two ends of the elastic member are squeezed between the support rod and the top wall of the accommodating inner cavity.

[0021] An elastic member is sleeved on the outer side of the rotating shaft. When the driving member drives the support rod to move upward, the elastic force of the elastic member helps the support rod to move upward, thereby reducing the load of the driving member driving the support rod to move upward. When the driving member drives the support rod to move downward, the elastic member forms a buffering effect when the support rod moves downward, thereby preventing the pot cover from hitting the pot body downward.

[0022] In some embodiments, a mounting seat is provided on the top wall of the accommodating inner cavity, the mounting seat is arranged on the mounting through hole, the thickness of the mounting seat is greater than the thickness of the top wall of the accommodating inner cavity, and the connecting member passes through the mounting seat in turn and is connected to the pot cover.

[0023] A mounting seat is provided on the top wall of the accommodating inner cavity, so that the connecting piece is more firmly inserted into the mounting through hole, thereby improving the stability of the connecting piece in moving up and down and rotating around the vertical axis.

[0024] In some embodiments, the cabinet is provided with a guide member, the guide member is provided with a guide channel and a groove located in the guide channel, the driving member is passed through the guide channel, a protrusion is provided on the outer wall of the driving member, the protrusion cooperates with the groove, and when the protrusion is aligned with the groove or is located in the groove, the pot cover is closed on the opening.

[0025] The driving member is inserted into the guide channel of the guide member, and the protrusion on the outer wall of the driving member cooperates with the groove in the guide channel, that is, the movement of the driving member is restricted by the cooperation between the protrusion and the groove, so that when the pot cover is closed on the opening of the pot body, the driving member moves back and forth along the guide channel, that is, the driving member drives the pot cover to rotate, thereby preventing the user from being confused in operating the driving member and causing the pot cover to fail to buckle on the opening of the pot body.

[0026] In some embodiments, the pot body is provided with a first buckle, and the pot cover is provided with a second buckle for engaging with the first buckle, and when the protrusion is located in the groove, the first buckle is engaged with the second buckle; when the protrusion is located outside the groove, the first buckle is disengaged from the second buckle.

[0027] The first buckle of the pot body cooperates with the second buckle of the pot cover to achieve rotational buckling of the pot body and the pot cover.

[0028] In some embodiments, the operating portion is provided with a handle, and the handle is located outside the cabinet.

[0029] A handle is provided on the operating portion of the driving member, so that the user can operate the driving member by holding the handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Reference Figures 1 to 10 The embedded electric pressure cooker lid opening and closing device of the present invention is implemented as follows:

[0047] The built-in electric cooker includes a cabinet 100, a support frame 200, a pot body 300, a pot cover 400, and a driving member. The cabinet 100 has an accommodating inner cavity 110, and an opening 111 is provided on the front side of the accommodating inner cavity 110. The opening 111 is connected to the outside. The support frame 200 is connected to the cabinet 100, 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. The above-mentioned built-in electric cooker can be installed in a cabinet without occupying space on the stove. When cooking with the built-in electric cooker, the support frame 200 is pulled out from the receiving cavity 110 of the cabinet 100, the food is added into the pot body 300, and the support frame 200 is pushed into the receiving cavity 110 of the cabinet 100, so that the electric cooker can be stored in the receiving cavity 110 of the cabinet 100 when working. After cooking, the support frame 200 is pulled out for use when food is needed. It can be seen that the use of the above-mentioned built-in electric cooker is also relatively convenient.

[0048] The pot cover 400 is arranged in the accommodating inner cavity 110, and the driving member 500 is connected to the pot cover 400, and the driving member drives the pot cover 400 and the opening 310 to open and close. The pot cover 400 is arranged in the accommodating inner cavity 110, and the pot cover 400 and the pot body 300 are driven to open and close by the driving member. The opening and closing actions of the pot cover 400 and the opening 310 of the pot body 300 are all completed in the accommodating inner cavity 110 of the cabinet 100, so that the pot cover 400 can effectively avoid occupying the kitchen space.

[0049] The pot body 300 can be an electric rice cooker or an electric pressure cooker, and the pot body 300 has a heating device, a power module, etc. in an electric cooker. Generally, the pot body 300 has inner and outer pots, pot teeth for connecting the pot cover 400, and other structures, that is, the pot body 300 has the functions and structures that a pot body in a conventional electric cooker should have, and the pot body 300 is a pot body of a conventional electric cooker well known to those skilled in the art. Among them, the electric connection wires, the electric control box, and other devices of the electric cooker can be arranged in the cabinet 100 or outside the cabinet 100, and a through hole can be provided on the side wall of the cabinet 100, and the through hole is used for the electric connection wires to pass through the accommodating inner cavity 110 of the cabinet 100, so as to facilitate the electric connection wires to connect the pot body 300 with the external circuit.

[0050] The function of the support frame 200 is mainly to enable the user to pull the pot body 300 out of the cabinet or push it into the cabinet. According to the common knowledge mastered by those skilled in the art, the specific implementation structure of the support frame 200 can be in many ways.

[0051] There are many ways for the driving member to drive the pot cover 400 and the opening 310 of the pot body 300 to open and close. For example, the driving member is an electric push rod, the driving member is installed in the accommodating inner cavity 110, and the movable end of the driving member is connected to the pot cover 400, so that the pot cover 400 is located above the pot body 300, and the movable end of the driving member drives the pot cover 400 to move in the up and down direction. When the support frame 200 is stored in the accommodating inner cavity 110, the movable end of the driving member drives the pot cover 400 to move downward and cover the opening 310 of the pot body 300, and the movable end of the driving member drives the pot cover 400 upward. Move and disengage from the opening 310; or, the driving member is a horizontally arranged pull rod, one end of the pull rod extends out of the cabinet 100, and the other end of the pull rod extends into the accommodating inner cavity 110, the pull rod can move in the horizontal direction, and the pull rod is connected to the pot cover 400, so that the pot cover 400 can move back and forth in the horizontal direction. When the support frame 200 is stored in the accommodating inner cavity 110, the opening 310 of the pot body 300 is located on the horizontal movement trajectory of the pot cover 400, and moving the pull rod makes the pot cover 400 move to the opening 310, so that the pot cover 400 covers the opening 310.

[0052] In some embodiments, the pot body 300 and the pot cover 400 are fastened by rotating each other after closing, and unlocked by rotating each other in the opposite direction. Figures 2 to 8 The driving member 500 is telescopically and rotatably arranged in the cabinet 100. The driving member 500 is provided with an operating portion and a connecting portion connected at an angle. The operating portion is exposed outside the cabinet 100, and the connecting portion is movably connected to the pot cover 400. During the telescopic process, the driving member 500 drives the pot cover 400 to rotate in the up-down direction to achieve locking or unlocking between the pot cover 400 and the pot body 300. During the rotation process, the driving member 500 drives the pot cover 400 to rise and fall in the up-down direction to achieve the closing or separation of the pot cover 400 and the pot body 300. There are many ways for the driving member 500 to drive the pot cover 400 to rise and fall and rotate in the up and down directions. For example, the driving member 500 is a vertically arranged straight rod, the operating part is exposed above the cabinet 100, the top of the connecting part is connected to the bottom of the operating part, and the bottom of the connecting part is connected to the top of the pot cover 400. The driving member 500 is rotated by hand to make the pot cover 400 rotate in the up and down direction, and the driving member 500 is lifted or lowered by hand to make the pot cover 400 rise and fall in the up and down direction.

[0053] In order to ensure that the pot body 300 and the pot cover 400 can be accurately covered, it is necessary to limit the freedom of translation and rotation of the pot body 300 on the support frame 200. Therefore, the pot body 300 can be fixedly connected to the support frame 200, or the pot body 300 can be connected to the support frame 200 by multiple connecting brackets, so as to ensure that when the support frame 200 is retracted into the accommodating cavity 110, the pot body 300 is located below the pot cover 400.

[0054] In some embodiments, in some embodiments, a mounting through hole 113 is provided on the top wall 112 of the accommodating inner cavity 110. A connecting member 410 is provided on the top of the pot cover 400, and the connecting member 410 can movably pass through the mounting through hole 113 and extend above the top wall 112 of the accommodating inner cavity 110. The driving member 500 is located outside the accommodating inner cavity 110, and the connecting portion of the driving member 500 is movably connected to the top of the connecting member 410, and the driving member 500 drives the connecting member 410 to move up and down and rotate around the up and down direction in the mounting through hole 113. The side wall of the accommodating inner cavity 110 separates the driving member 500 from the pot cover 400. When the electric pressure cooker is cooked, the driving member 500 drives the pot cover 400 to separate from the opening 310 of the pot body 300, and the humid gas inside the pot body 300 is intercepted by the accommodating inner cavity 110, thereby preventing the humid gas from corroding the driving member 500.

[0055] In some embodiments, the connecting member 410 is composed of a rotating shaft 411 and a support rod 412. The rotating shaft 411 is arranged vertically, the bottom end of the rotating shaft 411 is connected to the top of the pot cover 400, the upper part of the rotating shaft 411 passes upward through the mounting through hole 113, the top of the rotating shaft 411 is connected to the first end of the support rod 412, and the support rod 412 is linked to the rotating shaft 411. The second end of the support rod 412 protrudes from the outer periphery of the rotating shaft 411, and the second end of the support rod 412 is movably connected to the connecting part of the driving member 500. The connecting part of the driving member 500 drives the second end of the support rod 412 to rotate and move up and down around the axis of the rotating shaft 411. The second end of the support rod 412 rotates around the axis of the rotating shaft 411, thereby driving the rotating shaft 411 to rotate in the up and down direction, and the second end of the support rod 412 moves up and down, thereby driving the rotating shaft 411 to rise and fall in the up and down direction in the mounting through hole 113.

[0056] There are many ways for the driving member 500 to drive the second end of the support rod 412. For example, the driving member 500 includes a first horizontal linear push rod, a second horizontal linear push rod, and a vertical linear push rod. The movable end of the vertical linear push rod is connected to the second end of the support rod 412 to realize the up and down movement of the second end of the support rod 412. The first horizontal linear push rod and the second horizontal linear push rod are arranged on the top wall 112 of the accommodating inner cavity 110. The first horizontal linear push rod and the second horizontal linear push rod are respectively arranged on both sides of the second end of the support rod 412. When the movable end of the vertical linear push rod is at the bottom end of the stroke, the movable end of the first horizontal linear push rod and the movable end of the second horizontal linear push rod are respectively located on two opposite sides of the second end of the support rod 412. The movable end of the first horizontal linear push rod pushes the second end of the support rod 412 to rotate forward, and the movable end of the second horizontal linear push rod pushes the second end of the support rod 412 to rotate reversely, thereby realizing that the driving member 500 drives the second end of the support rod 412 to rotate around the axis of the rotating shaft 411.

[0057] In some embodiments, a hinge through hole 413 is provided on the second end of the support rod 412, and a connecting column 510 is provided on the second end of the driving member 500. The connecting column 510 can be movably inserted into the hinge through hole 413. The diameter of the connecting column 510 is smaller than the aperture of the hinge through hole 413, so that the connecting column 510 can move in the hinge through hole 413. A stop block 511 is provided at the end of the connecting column 510, and the edge of the stop block 511 expands outward so that the edge of the stop block 511 protrudes from the outer periphery of the hinge through hole 413, so that the stop block 511 prevents the hinge through hole 413 from detaching from the connecting column 510.

[0058] In some embodiments, an elastic member 414 is sleeved on the outer side of the rotating shaft 411. The elastic member 414 can be a device that can return to its original shape after being compressed, such as a compression spring, elastic rubber, or elastic sponge. The two ends of the elastic member 414 are squeezed between the support rod 412 and the top wall 112 of the accommodating inner cavity 110, so that the elastic member 414 has an elastic force to push the support rod 412 upward. When the support rod 412 moves downward, the elastic member 414 helps to reduce the impact force of the pot cover 400 falling, thereby preventing the pot cover 400 from colliding with the pot body 300; when the support rod 412 moves upward, due to the heavy weight of the pot cover 400, the elastic force of the elastic member 414 helps to reduce the load required for the driving member 500 to drive the support rod 412 to move upward, thereby reducing the burden of the driving member 500.

[0059] In some embodiments, a mounting seat 114 is provided on the top wall 112 of the accommodating inner cavity 110, and the mounting seat 114 is arranged on the mounting through hole 113. The thickness of the mounting seat 114 in the up and down directions is greater than the thickness of the top wall 112, thereby increasing the axial length of the mounting through hole 113. The connecting piece 410 is connected to the pot cover 400 after passing through the mounting through hole 113 and the mounting seat 114. The mounting through hole 113 and the mounting seat 114 increase the contact length of the connecting piece 410 with the top wall 112 of the accommodating inner cavity 110, which helps to improve the stability of the connecting piece 410 in the mounting through hole 113 and prevent the connecting piece 410 from swinging in the mounting through hole 113.

[0060] In some embodiments, a guide member 120 is provided on the cabinet 100, and the guide member 120 is provided with a guide channel 121, and a groove 122 is provided on the inner wall of the guide channel 121. The driving member 500 is inserted into the guide channel 121 of the guiding member 120, and a protrusion 520 is provided on the outer wall of the driving member 500, and the protrusion 520 cooperates with the groove 122. When the protrusion 520 is aligned with the groove 122, the pot cover 400 covers the opening 310; when the driving member 500 is pulled, the protrusion 520 of the driving member 500 moves in the groove 122, driving the pot cover 400 to rotate in the covered state, so as to achieve locking or unlocking between the pot cover 400 and the pot body 300. It can be seen that by setting the cooperation between the protrusion 520 and the groove 122, the correct operation of the user can be guided.

[0061] In some embodiments, the pot body 300 is provided with a first buckle, and the pot cover 400 is provided with a second buckle. The first buckle and the second buckle are matched to form a buckle connection. When the protrusion 520 is located in the groove 122, the first buckle and the second buckle are buckled; when the protrusion 520 is located outside the groove 122, the first buckle and the second buckle are disengaged. Thereby, the driving member 500 drives the pot cover 400 and the pot body 300 to buckle and unscrew. In this scheme, the length of the groove 122 is obviously equal to or greater than the arc length of the pot cover 400. When the pot cover 400 and the pot body 300 are locked, the scheme can use the groove 122 to limit the protrusion 520, further limit the driving member 500, and guide the user to operate correctly.

[0062] In some embodiments, the operating portion of the driving member 500 passes through the side wall of the cabinet 100 , and the operating portion of the driving member 500 is provided with a handle 530 , which is located outside the cabinet 100 , thereby facilitating the user to operate the driving member 500 outside the cabinet 100 .

[0063] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
