Description

Technical Field

[0001] The invention relates to the field of cooking utensils, in particular to a pot cover device 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 a lid device for 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 pot cover device for an embedded electric pressure cooker, comprising:

[0006] The cabinet body is provided with a containing inner cavity, one side of the containing inner cavity is provided with an opening, and the opening is connected to the outside;

[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 driving member, which is arranged on the cabinet;

[0011] A movable part, the movable part is connected to the pot cover;

[0012] The guide member is arranged on the cabinet and is provided with a guide rail. The driving member drives the movable member to move on the guide rail of the guide member to drive the pot cover and the pot body to open and close.

[0013] The beneficial effects of the present invention are as follows: the pot body is arranged on the supporting frame, and when the supporting frame is folded into the accommodating inner cavity of the cabinet, when the pot cover needs to be closed with the pot body, the driving member drives the movable member to move on the guide rail of the guiding member to realize the opening and closing action of the pot cover and the pot body, and the opening and closing action of the pot cover and the pot body are all completed in the accommodating inner cavity of the cabinet, thereby effectively avoiding the pot cover from occupying kitchen space.

[0014] As a further improvement of the above technical solution, the guide rail includes a first guide portion arranged longitudinally and a second guide portion arranged transversely, and the second guide portion is arranged at the bottom end of the first guide portion.

[0015] The second guide portion is arranged at the bottom end of the first guide portion. When the pot cover needs to be closed with the pot body, the driving member drives the movable member to move downward along the longitudinal first guide portion to the transverse second guide portion, and the movable member drives the pot cover to descend to the opening of the pot body, and the second guide portion limits the freedom of the movable member to descend, so that the movable member rotates in the positive direction along the second guide portion, and the pot cover rotates in the positive direction and engages with the pot body; when the pot cover needs to be opened with the pot body, the driving member drives the movable member to rotate in the opposite direction. Since the transverse second guide portion limits the freedom of the movable member to rise, the movable member rotates in the opposite direction along the second guide portion, and the pot cover rotates in the opposite direction and loosens from the pot body. Subsequently, the movable member disengages from the second guide portion and abuts against the longitudinal first guide portion, and the driving member drives the movable member to move upward along the longitudinal first guide portion, so that the pot cover rises and opens from the opening of the pot body; by using the second guide portion to limit the freedom of rotation of the pot cover, the guide member realizes that the lifting and lowering and rotation of the pot cover are divided into two actions, which are used to adapt to the rotational engaging action of the pot cover and the pot body, so that the covering and opening of the pot cover and the pot body are smoother.

[0016] As a further improvement of the above technical solution, the guide member is a hollow structure, the guide member has a penetrating inner hole, the driving member passes through the inner hole, the movable member can be movably arranged in the inner hole, and the guide rail is arranged on the inner wall of the guide member.

[0017] The guide member has an inner hole, the driving member is located in the inner hole, and the movable member moves along the guide rail in the inner hole, so that the driving member and the movable member are protected by the guide member.

[0018] As a further improvement of the above technical solution, the inner hole is a circular hole, the shape of the movable part matches the shape of the inner hole, the first guide portion is a groove extending axially along the inner hole, the second guide portion is a groove extending circumferentially along the inner hole, and a protrusion is provided on the outer wall of the movable part, and the protrusion can be slidably arranged in the first guide portion or the second guide portion.

[0019] The inner hole of the guide member is a circular hole, and the shape of the inner hole matches the outer shape of the movable member. The movable member can rotate or move up and down in the inner hole. A protrusion is provided on the outer wall of the movable member, and the protrusion can be slidably set in the first guide part or the second guide part. The movable member cooperates with the guide member to realize the two-stage action of lifting and lowering the movable member or rotating around the vertical axis, and the cooperation between the movable member and the guide member is more compact.

[0020] As a further improvement of the above technical solution, the accommodating inner cavity has a top wall, the top wall is located above the pot cover, the top wall is provided with a mounting through hole, and the guide member cover is arranged in the mounting through hole.

[0021] Since steam often comes out when the lid of the electric pressure cooker is opened after cooking, the top wall of the accommodating inner cavity separates the driving part from the lid, the guide part is sealed on the mounting through hole of the top wall, and the inner hole of the guide part matches the shape of the movable part, so that the steam generated when the electric pressure cooker is working is blocked in the accommodating inner cavity to prevent the steam from corroding the driving part.

[0022] As a further improvement of the above technical solution, the driving member is a transmission screw rod, the driving member extends in the up and down directions, the movable member is sleeved on the driving member, and the driving member is meshed with the movable member for transmission.

[0023] The driving member is a transmission screw, and the movable member is sleeved on the transmission screw, so that the driving member drives the movable member to rise and fall in the up and down directions and rotate around the vertical axis. The transmission screw and the transmission nut have high matching accuracy, which makes the rotation accuracy of the pot cover lifter high.

[0024] As a further improvement of the above technical solution, the movable part includes:

[0025] An outer cylinder having a mounting hole extending in an up-down direction;

[0026] A nut is detachably arranged in the assembly hole, and the shape of the nut matches the shape of the assembly hole so that the nut and the outer cylinder are linked.

[0027] The movable part includes a nut and an outer cylinder. The assembly hole of the outer cylinder cooperates with the nut to realize the linkage between the outer cylinder and the nut. The nut is easy to wear during the transmission engagement process with the driving member, and the nut is detachably arranged in the assembly hole, so that the nut is easy to disassemble and replace.

[0028] As a further improvement of the above technical solution, the driving member includes a motor and a screw rod, the output shaft of the motor is connected to the screw rod, and the axial direction of the screw rod is in the up and down direction.

[0029] The output shaft of the motor drives the lead screw to rotate, so that the driving member drives the movable member to move up and down and rotate around the vertical axis. The output shaft of the motor is directly connected to the lead screw, which makes the structure of the driving member simple and easy to assemble.

[0030] As a further improvement of the above technical solution, the pot cover device of the embedded electric pressure cooker 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.

[0031] 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.

[0032] As a further improvement of the above technical solution, the limiting structure is detachably connected to the supporting frame.

[0033] 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. BRIEF DESCRIPTION OF THE DRAWINGS
