Description

Technical Field

[0001] This utility model relates to the technical field of kitchen household appliances, and more specifically to a cooking utensil. Background Technology

[0002] Existing pressure cooking appliances, such as pressure rice cookers, have a sealing ring on the lid to form a seal at the rim of the inner pot. However, during cooking, the pressure within the cooking space is very high, and the sealing ring and the rim may not seal tightly, leading to air leakage. To prevent air leakage at the rim, some appliances have a movable fastener on the lid. This fastener locks the rim to maintain a seal between the sealing ring and the rim. However, the fastener has only one connection point, making it prone to tilting upwards when pressed down in the cooking space. This results in insufficient locking force with the rim, thus affecting the sealing effect.

[0003] Therefore, a cooking appliance is needed to at least partially solve the above problems. Utility Model Content

[0004] The description of this utility model introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, this utility model provides a cooking utensil, comprising a lid and a pot body. The lid is closable and can be opened and closed within the pot body to form a cooking space between the lid and the pot body. The pot body includes a pot inner liner, and the lid includes:

[0006] Liner;

[0007] Inner cover assembly;

[0008] A locking and unlocking assembly is located above the inner cover assembly and mounted to the liner. The locking and unlocking assembly includes fastening members spaced circumferentially along the inner cover assembly and partially extending beyond its outer periphery. The fastening members have a connecting position on the outer side of their radially inner end. The fastening members are movable radially along the inner cover assembly between a locked position engaged with the pot opening and an unlocked position disengaged from the pot opening.

[0009] A reinforcing member is fixed to the liner and located above the fastener. The reinforcing member can abut against the radially inner end of the fastener in at least the locked position to restrict upward movement of the fastener in at least the locked position.

[0010] According to this design, when the lid is closed and the cooking space is pressurized, the fastener hooks onto the rim of the inner pot, ensuring a tighter seal between the rim sealing ring and the rim. The reinforcing member enhances the structural strength of the lid, preventing deformation due to excessive pressure within the cooking space and improving product reliability. Furthermore, the reinforcing member provides downward pressure at the radially inner end of the fastener, restricting upward movement of this end and preventing it from warping upwards under pressure in the cooking space. This ensures a secure and reliable connection between the fastener and the rim, maintaining effective locking force and resulting in a better seal, thus improving product reliability and safety.

[0011] Optionally, the fastening member includes an upper locking portion, and at least one of the upper locking portion and the reinforcing member has a protrusion, through which the upper locking portion can abut against the reinforcing member. According to this solution, by providing the protrusion, the gap between the upper locking portion and the reinforcing member can be reduced, so that the fastening member and the reinforcing member can abut against each other at least when pressed without changing their respective mounting surfaces.

[0012] Optionally, the radially inner end of the upper locking part is provided with an upwardly protruding first protrusion, and the reinforcing member is provided with a downwardly protruding second protrusion. The second protrusion is located below the first protrusion and can abut against the first protrusion. According to this solution, the mounting surfaces of the fastener and the reinforcing member have a certain height difference, which facilitates the setting of the respective mounting structures of these two components. The gap is further reduced by the protrusions on these two components, so that the reinforcing member can limit the fastener.

[0013] Optionally, the fasteners and / or reinforcing members are made of plate-like material and formed into protrusions through partial bending. According to this solution, the structural strength of the component to which the protrusion belongs can be enhanced, preventing deformation of the component with the protrusion.

[0014] Optionally, the reinforcing member is an elongated strip extending along the front-rear direction of the cover and spaced apart along the left-right direction of the cover, with each reinforcing member extending through at least two fastening members. According to this solution, the front-rear dimension of the cover is larger than its left-right dimension, and the reinforcing members positioned in the front-rear direction provide better reinforcement to the cover; furthermore, one reinforcing member simultaneously limits two or more fastening members, which reduces the number of reinforcing members and improves the installation efficiency of the cover due to the reduction in the number of components.

[0015] Optionally, the radial dimension of the portion of the reinforcing member that abuts against the fastener in the inner cover assembly is greater than or equal to the radial movement distance of the fastener, so that the fastener can abut against the reinforcing member when moving between the locked and unlocked positions. According to this solution, the reinforcing member can limit the movement of the fastener during its radial movement, preventing the fastener from lifting during movement, thus resulting in higher overall stability and reliability of the fastener's movement.

[0016] Optionally, the reinforcing member has upwardly folded ribs on both sides in its width direction, and the ribs extend along the length direction of the reinforcing member. According to this solution, by providing ribs, the structural strength of the reinforcing member can be further enhanced, and deformation of the reinforcing member can be prevented.

[0017] Optionally, the fastener is located on the lower side of the liner, and the reinforcing member is fixed to the liner from the upper side. The liner has clearance openings at positions corresponding to the fasteners, and the radially inner end of the fastener abuts against the reinforcing member through the clearance openings. According to this solution, the radially inner end of the fastener extends from the clearance openings so that the reinforcing member can simultaneously provide anti-deformation force to the liner from the upper side and provide downward pressure to the radially inner end of the fastener.

[0018] Optionally, the reinforcing member is arranged along the length of the cover. The cover has a slot at the front end and mounting posts at the middle and rear ends. The front end of the reinforcing member is inserted into the slot, and the middle and rear ends are fixed to the mounting posts. According to this solution, the installation of the reinforcing member is simple and easy to perform through the slot and mounting posts on the cover.

[0019] Optionally, the cover opening assembly further includes a rotating frame, which is rotatably connected to the liner about a first axis passing through the center of the inner cover assembly. The fastening element is movably connected to the rotating frame at a connection position to move radially as the rotating frame rotates. A reinforcing member is located on the underside of the rotating frame. According to this design, the rotational movement of the rotating frame can drive the fastening element to move radially. The rotating frame is a rotational transmission component for the fastening element. Compared to a linear transmission component, a rotational transmission component can simultaneously drive more fastening elements to move radially, resulting in higher transmission efficiency. The reinforcing member can better separate the rotating frame and the fastening element, preventing interference between them. Attached Figure Description

[0085] like Figures 1 to 15As shown, this application provides a cooking appliance. The cooking appliance may include a pot body 100 and a lid 110. The pot body 100 is used for cooking food. The lid 110 is used to cover the pot body 100. For example, the lid 110 is connected to the pot body 100 in an openable and closable manner to cover the pot body 100. When the lid 110 covers the pot body 100, a cooking space is formed between the lid 110 and the pot body 100.

[0086] The pot body 100 includes a pot inner 101 and a heating device 102. The pot inner 101, used to hold food, is removably installed in the pot body 100. When the lid 110 closes the pot body 100, a cooking space is formed between the lid 110 and the pot inner 101. The heating device 102 is located at the bottom of the pot body 100, below the pot inner 101, to heat the food in the pot inner 101. The pot body 100 also includes a base 107, an outer shell 108, and a middle plate 109 that form spaces for accommodating the pot inner 101, heating device 102, etc. The upper end of the outer shell 108 is connected to the middle plate 109, and its lower end is connected to the base 107. The middle plate 109 and the base 107 are internally connected by a plurality of screw posts and a plurality of screws.

[0087] The lid 110 is rotatably connected to the pot body 100 via a pivot about a rotation axis AX. The rotation axis AX is located at one end of the pot body 100 in the front-rear direction D1. A torsion spring is mounted on the pivot, with its two ends abutting against the lid 110 and the pot body 100 respectively, allowing the torsion spring to apply an elastic force to the lid 110 away from the pot body 100. When the lid 110 is opened, it springs upward under the elastic force of the torsion spring and rotates about the pivot.

[0088] The cover 110 includes a top cover 111, a liner 112, and an inner cover assembly 113. The top cover 111 is located on the outermost (i.e., uppermost) side of the cover 110, forming the outer shell of the cover 110. The liner 112 is located below the top cover 111 and is connected to it. For example, the liner 112 can be connected to the top cover 111 via fasteners or snap-fits. The liner 112 is primarily used to centrally mount various functional components of the cover 110 that sense and control the operating status of the cooking appliance, such as sensors. The inner cover assembly 113 is located on the innermost (i.e., lowermost) side of the cover 110 and is located below the liner 112. The inner cover assembly 113 is detachably connected to the liner 112, for example via snap-fits, for easy cleaning and replacement. The inner cover assembly 113 includes an inner cover 113a, a retaining ring 113b, and a pot opening sealing ring 113c. The pot opening sealing ring 113c is fixed to the outer periphery of the inner cover 113a by the retaining ring. When the cover is closed, the pot opening sealing ring 113c abuts against the pot opening 101a of the inner pot 101 to form a seal.

[0089] The cover 110 is provided with a channel assembly for forming a steam passage 110a. Exemplarily, the channel assembly includes a steam valve 114 and a steam seal 116. The steam valve 114 has a vent (not shown) communicating with the outside environment. The cooking space communicates with the external environment through the steam passage 110a to release steam generated during cooking. The steam seal 116 is located below the steam valve 114 and forms a seal between the steam valve 114 and the inner cover 113a.

[0090] The cooking appliance also includes an electrically operated pressure relief device 120. The electrically operated pressure relief device 120 is located on the lid 110 and is used to open and close the steam passage 110a. See also... Figure 2 , Figures 4 to 6 For example, the electric pressure relief device 120 may include a pressure relief assembly 120a having a steam venting passage 110b and an electric drive assembly 120b capable of opening and closing the steam venting passage 110b. The pressure relief assembly 120a is disposed within and communicates with the steam passage 110a in the inner cover assembly 113, and is removable from the cover along with the inner cover assembly 113. The electric drive assembly 120b is disposed in the liner and located on one side of the steam passage 110a in the horizontal direction. Exemplarily, the pressure relief assembly 120a includes a pressure ball 121 for sealing the steam venting passage 110b. The electric drive assembly 120b drives the pressure ball 121 to move between an open position (opening the steam venting passage 110b) and a closed position (closing the steam venting passage 110b). When the pressure ball 121 is in the open position, the steam venting passage 110b is opened, and the steam passage 110a communicates with the cooking space via the steam venting passage 110b. When the pressure ball 121 is in the closed position, the steam venting passage 110b is blocked by the pressure ball 121, and the steam passage 110a is not connected to the cooking space in order to realize the cooking function that requires pressurization or pressure increase.

[0091] The electric drive assembly 120b includes an electric drive element 122 and a push rod 123. One end of the push rod 123 is connected to the output shaft of the electric drive element 122, and the other end abuts against a pressure ball 121. The electric drive element 122 drives the push rod to move linearly to keep the pressure ball 121 in the open position. When the force of the push rod 123 is removed, the pressure ball 121 returns to the closed position under gravity. Optionally, the electric drive element 122 is a push-pull electromagnet.

[0092] See Figure 2 , Figure 4 and Figure 5The cooking appliance may also include a locking / unlocking assembly 130, which enables a tighter seal between the pot opening sealing ring 113c and the pot opening portion 101a. The locking / unlocking assembly 130 includes two or more fastening elements 131, a rotating frame 132, and a drive motor 134. The two or more fastening elements 131 are arranged circumferentially spaced along the inner lid assembly 113, or the inner lid 113a, and each fastening element 131 partially extends beyond the outer periphery of the inner lid assembly 113. The fastening elements 131 are radially movable along the inner lid assembly 113, or the inner lid 113a, between a locked position and an unlocked position. When the fastening element 131 is in the locked position, it engages / hooks onto / encloses the pot opening portion 101a of the inner pot 101 from below, clamping the pot opening portion 101a and the outer periphery of the inner lid assembly 113. This ensures a tighter seal between the pot opening sealing ring 113c and the pot opening 101a, preventing insufficient pressure due to air leakage and thus affecting cooking performance. When the fastener 131 is in the unlocked position, it disengages from the pot opening 101a, allowing the lid to be opened. The rotating frame 132 is rotatably connected to the liner 112 about the first axis AX1 between the third extreme position P3 and the fourth extreme position P4. The first axis extends vertically and passes through the center of the inner cover assembly 113, or more precisely, the center of the inner cover 113a. The fastener 131 is movably connected to the rotating frame 132 and moves radially as the rotating frame 132 rotates. The drive motor 134 drives the rotating frame 132 to rotate.

[0093] It should be noted that the circumferential and radial directions of the inner lid assembly 113 / inner lid 113a in this article are based on the first axis, and therefore can also be described as circumferential and radial directions based on the first axis. In order to hook the pot opening 101a, the fastener 131 may include a clamp for accommodating the pot opening 101a of the inner pot 101 and the outer periphery of the inner lid assembly 113.

[0094] Continue reading Figures 2 to 5 , Figures 9 to 13 The rotating frame 132 is provided with two or more transmission holes 132a corresponding to the fastening member 131. The fastening member 131 is slidably connected to the transmission hole 132a along its extension direction. When the rotating frame 132 rotates, the fastening member 131 moves within the transmission hole and is guided by the transmission hole to move radially between a locked position and an unlocked position. The transmission hole can convert the rotational motion of the rotating frame 132 into the linear motion of the fastening member 131. The transmission hole is an elongated hole and includes at least a straight segment, the angle between the extension direction of the straight segment and the radial direction of the inner cover 113a extending through the fastening member 131 is an acute angle. The rotating frame 132 is drive-connected to the drive motor 134. When the rotating frame 132 rotates to the third limit position P3, the fastening member 131 is in the unlocked position. When the rotating frame 132 rotates to the fourth limit position P4, the fastening member 131 is in the locked position.

[0095] See Figure 4 , Figure 5 The fastening member 131 is connected to the corresponding transmission hole 132a via a guide connector 137. The guide connector 137 may include fasteners such as screws or bolts. The guide connector 137 is connected to the fastening member 131. The guide connector 137 is located within the transmission hole 132a and is movable relative to the transmission hole 132a. The transmission of the rotating frame is transmitted to the fastening member 131 via the guide connector, which is capable of sliding relative to the transmission hole. During the rotation of the rotating frame 132, the fastening member 131 achieves radial movement within the inner cover assembly 113 through the sliding engagement of the guide connector 137 and the transmission hole 132a.

[0096] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figures 10 to 12 The cooking appliance may also include a transmission component, through which the output shaft 134a of the drive motor 134 can be connected to the rotating frame 132 to drive the rotating frame 132 to rotate. The transmission component is configured as a rotatable transmission arm 133. Exemplarily, the transmission arm 133 has opposite active ends 133a and driven ends 133b. The transmission arm 133 is rotatable about a second axis located at the active end, and the driven end is connected to the rotating frame 132 and drives the rotating frame 132 to rotate. The second axis extends vertically and is parallel to the first axis. The active end 133a is connected to the output shaft 134a of the drive motor 134 to receive the rotational force of the drive motor to rotate the transmission arm. The rotation direction of the transmission arm 133 is the same as that of the output shaft 134a of the drive motor 134, and the rotation direction of the transmission arm 133 is opposite to that of the rotating frame 132.

[0097] During the rotation of the transmission arm 133 in the first rotation direction R1, the rotating frame 132 rotates in the second rotation direction R2, which is opposite to the first rotation direction R1, causing the fastening member 131 to move towards the locked position. During the rotation of the transmission arm 133 in the second rotation direction R2, the rotating frame 132 rotates in the first rotation direction R1, causing the fastening member 131 to move towards the unlocked position. The power of the drive motor 134 is transmitted to the rotating frame 132 through the transmission arm 133, which facilitates the reasonable arrangement of the positions of the rotating frame 132 and the drive motor 134.

[0098] See Figure 2 , Figure 3 , Figures 4 to 12Optionally, the drive motor 134 can drive the transmission arm 133 to rotate along the second rotation direction R2 to the first limit position P1, thereby causing the rotating frame 132 to rotate to the third limit position P3, and thus causing the fastening member 131 to move to the unlocked position. The drive motor 134 can also drive the transmission arm 133 to rotate along the first rotation direction R1 to the second limit position P2, thereby causing the rotating frame 132 to rotate to the fourth limit position P4, and thus causing the fastening member 131 to move to the locked position.

[0099] See Figure 3 , Figures 4 to 7 , Figures 9 to 12 Optionally, the cooking appliance may also include a force transmission element 135. This force transmission element 135 is connected to the active end 133a. By manually applying a torsional force to the drive arm 133 at the force transmission element 135, the rotating frame 132 can be driven to rotate, thereby moving the fastener 131 to the unlocked position. Here, the force transmission element 135 can be configured as a lever.

[0100] See Figure 7 and Figure 8 Optionally, the driving end 133a has a hole for connecting the output shaft 134a of the drive motor 134. The output shaft 134a is inserted into the hole of the driving end 133a. Exemplarily, the output shaft 134a also has a locking recess 134b, and correspondingly, the inner wall of the hole in the driving end 133a has a locking boss 133a1. Through the cooperation of the locking recess 134b and the locking boss 133a1, the driving end 133a can be locked to the output shaft 134a to prevent the driving end 133a from disengaging from the output shaft 134a.

[0101] See Figure 12 and Figure 13 Furthermore, the rotating frame 132 has a connecting hole 132e. The transmission arm 133 also has a connecting rod 133c. The connecting rod 133c is inserted into the connecting hole 132e. The connecting hole 132e provides allowance for radial movement of the connecting rod 133c relative to the rotating frame 132. For example, the connecting hole 132e can be configured as an elongated shape extending radially based on the first axis AX1, such as an oblong hole, a square hole with rounded corners, etc. The connecting hole 132e can be a through hole or a blind hole. The connecting hole 132e is located at the edge of the rotating frame 132.

[0102] It is understandable that in other examples, the positions of the connecting hole and the connecting rod can be interchanged; that is, the connecting hole can be set in the transmission arm, and the connecting rod can be set in the rotating frame.

[0103] See Figure 4 and Figure 5Optionally, the cover 110 also includes a float device 136, with a corresponding through hole in the inner cover 113a. The float device 136 controls the pressure within the cooking space via this through hole. A rotating frame 132 is located between the liner 112 and the top cover 111. The rotating frame 132 has a limiting hole 132b at a distance offset from the first axis AX1. When the fastener 131 is in the locked position, the limiting hole 132b and the float device 136 are aligned. When pressure is applied to the cooking space, the float in the float device 136 moves upward and inserts into the limiting hole 132b. This prevents the rotating frame 132 from rotating. When the cooking space is under normal pressure, the float disengages from the limiting hole 132b. At this time, the rotating frame 132 can rotate relative to the liner 112.

[0104] See Figure 11 and Figure 13 For example, the rotating frame 132 includes an annular frame body 132c and support beams 132d. The support beams 132d are staggered and connect to the frame bodies 132c at different positions to form clearance gaps 132g. Two or more fasteners 131 are connected to the frame bodies 132c. The support beams 132d are rotatably connected to the cover 112 at positions through which the first axis AX1 passes. These clearance gaps 132g are designed to avoid interference with electrical structures or mechanical structures such as electrical components, devices, and electrical elements located between the rotating frame 132 and the cover 112, or between the rotating frame 132 and the faceplate 111.

[0105] See Figure 4 , Figure 5 , Figures 9 to 12 , Figures 14 to 15 Optionally, the pot body 100 includes a button assembly 103 and a stop-open assembly 140. The button assembly 103 is located at the front end of the pot body 100. The button assembly 103 is configured to automatically switch to a locked state after the lid 110 is closed with the pot body 100, and to switch to an unlocked state when pressed by an external force, thereby facilitating the opening of the lid 110. The stop-open assembly 140 is used to prevent the button assembly 103 from switching from the locked state to the unlocked state. The rotating frame 132 may include a pushing part 132f. The pushing part 132f is used to abut against the stop-open assembly 140 during the rotation of the rotating frame 132 around the first axis AX1, so that the stop-open assembly 140 can abut against the button assembly 103 when the lid 110 is closed with the pot body 100, thereby preventing or allowing the button assembly 103 from switching from the locked state to the unlocked state.

[0106] With the lid 110 closed on the pot body 100, when the rotating bracket 132 rotates to the position where the fastening member 131 is in the locked position, the pushing part 132f abuts against the anti-opening component 140, preventing the button assembly 103 from switching from the locked state to the unlocked state. This adds an extra layer of safety to the cooking appliance, preventing the button assembly 103 from being accidentally operated when the fastening member 131 is in the locked position, thus improving the safety of the cooking appliance.

[0107] See Figures 9 to 12 Specifically, the button assembly 103 may include a button 104, a lower hook 105, and a first elastic element 106. The button 104 is connected to the lower hook 105. The first elastic element 106 is connected to either the button 104 or the lower hook 105, and is used to directly or indirectly reset the button 104 automatically. That is, the first elastic element 106 is the button's reset elastic element. After the button 104 is reset, the button assembly 103 is in a locked state. The lower hook 105 is rotatably connected to the body 100 at its center, and its lower part is connected to the button. The lower hook 105 is rotatable in the inward and outward directions about a third axis AX3 extending horizontally. The cover 110 is provided with an upper hook 115. The lower hook 105 can rotate between the position where it is hooked onto the upper hook 115 and the position where it is disengaged from the upper hook 115, thereby achieving the purpose of locking and unlocking.

[0108] The stop assembly 140 is in the stop position where the hook 105 is disengaged from the upper hook 115 (see [reference]). Figure 11 ) and the clearance position that allows the lower hook 105 to disengage from the upper hook 115 (see Figure 12 The locking assembly 140 is movably positioned between the upper hook and the lower hook 115. When the lid 110 is closed and the cooking space is pressurized, the locking assembly 140 prevents the lower hook 105 from rotating, keeping it in the locked position hooked to the upper hook 115. This avoids the risk of burns from high-pressure gas due to accidental opening of the lid, improving product safety. Under normal pressure, the locking assembly 140 moves away from the lower hook 105 when the lid is opened, without restricting its rotation, allowing the lid to be opened after unlocking.

[0109] See Figure 11 , Figure 12 , Figure 15The stop assembly 140 is disposed on the cover 112 and located on the front side of the pusher 132f in the circumferential direction. Exemplarily, the stop assembly 140 may include a limiting lever 141, a pivot 142, and a second elastic member 143. The middle portion of the limiting lever 141 is rotatably connected to the cover 112 via the pivot 142 about a fourth axis AX4. The fourth axis AX4 passes through the middle portion of the limiting lever 141 and extends in the front-rear direction, intersecting the circumferential reference line of the pusher 132f. The limiting lever 141 is rotatable between a stop position that prevents the lower hook 105 from disengaging from the upper hook 115 and a clearance position that allows the lower hook 105 to disengage from the upper hook 115. When pushed by the pusher 132f, the limiting lever 141 rotates to the stop position, at which point the lower portion of the limiting lever 141 abuts against the lower hook 105. When the limiting lever 141 separates from the pushing part 132f, it rotates to the avoidance position, at which point the lower part of the limiting lever 141 moves away from the lower hook member 105. A second elastic member 143 is connected between the limiting lever 141 and the cover 112, and is used to apply an elastic force to the limiting lever 141 to rotate towards the avoidance position. In other words, the second elastic member 143 is a reset elastic member for the limiting lever 141. The second elastic member 143 can be, for example, a torsion spring.

[0110] The movement of the stop assembly 140 is achieved through the pusher 132f on the rotating frame 132. Specifically, the limit lever 141 is pushed up and down by the circumferentially moving pusher 132f, thereby blocking and releasing the lower hook 105. The limit lever 141 is separate from the rotating frame 132, allowing these two components to be manufactured and spatially arranged separately, which helps to simplify the structure and optimize the space of the internal components of the cover; the transmission form between the rotating frame 132 and the limit lever 141 is simple and the transmission reliability is higher.

[0111] Specifically, the limiting lever 141 includes a stop portion 141a and a transmission portion 141b located on both sides of the fourth axis AX4. The stop portion 141a and the transmission portion 141b move in opposite directions in the height direction D3. The transmission portion 141b extends horizontally and can abut against the pushing portion 132f in the height direction D3, while the stop portion 141a extends partially downward to abut against the lower hook member 105. The stop portion 141a moves downward until its lower part is located outside the lower hook member 105 to restrict the outward rotation of the lower hook member 105. The limiting lever 141 has a horizontal portion and a vertical portion. The pushing portion 132f of the horizontal portion can cooperate with the transmission portion 141b in the height direction D3, and the stop portion 141a of the vertical portion extends into or away from the position of the lower hook member 105. The overall structure of the limiting lever 141 is simple and easy to manufacture. The transmission unit 141b has a downward-facing transmission surface 141c, which is configured to gradually extend upward from one end near the fourth axis AX4. For example, the transmission surface 141c is an inclined surface, a curved surface, or an arc surface. The surface of the pushing unit 132f that contacts the transmission surface 141c is an inclined surface, a curved surface, or an arc surface with a small circumferential dimension. The pushing unit 132f can abut against the transmission surface 141c from below to push the transmission unit 141b upward. The stop part 141a extends into or away from the lower hook member 105 from the upper side.

[0112] like Figures 16 to 21 As shown, the cover 110 also includes a reinforcing member 150. The reinforcing member 150 is fixed to the liner 112. The reinforcing member 150 enhances the structural strength of the liner 112, preventing deformation of the liner 112 due to excessive pressure within the cooking space, thus improving the product's reliability. Figure 17 As shown, the reinforcing member 150 has upwardly folded ribs 151 on both sides in its width direction, and the ribs 151 extend along the length direction of the reinforcing member 150. By providing the ribs 151, the structural strength of the reinforcing member 150 can be further enhanced, and deformation of the reinforcing member 150 can be avoided.

[0113] See Figure 19 The fastener 131 has a connection point P on the outer side of its radially inner end 156. The connection point P is defined by a guide connector 137, which is further disposed on the outer side of the radially inner end 156 of the fastener 131. When the fastener 131 is pressed into the cooking space, its radially inner end 156 is prone to tilting upward. To prevent the fastener 131 from tilting upward, a reinforcement 150 is located above the fastener 131, and the reinforcement 150 can abut against the radially inner end 156 of the fastener 131 in at least the locked position to limit the upward movement of the fastener 131 in at least the locked position. Figure 18 and Figure 19The relative position of the fastener 131 in the locked position and the reinforcing member 150 is shown. It should be noted that "abuttable" here includes abutment without gaps or abutment after gaps are eliminated under certain conditions. Specifically, the reinforcing member 150 directly abuts against the radially inner end 156 of the fastener 131, or there is a small gap between them, allowing the fastener 131 to abut against the reinforcing member 150 by slightly moving the radially inner end 156 upwards. With this configuration, the reinforcing member 150 can provide downward pressure on the radially inner end 156 of the fastener 131, restricting upward movement of the radially inner end 156, thereby preventing the fastener 131 from tilting upwards when pressed in the cooking space. This ensures a firm and reliable connection between the fastener 131 and the pot opening 101a, maintaining effective locking force, resulting in a better seal and improved product reliability and safety.

[0114] Optionally, the portion of the reinforcing member 150 that abuts against the fastener 131 has a radial dimension greater than or equal to the radial movement distance of the fastener 131 in the inner cover assembly 113, so that the fastener 131 can abut against the reinforcing member 150 when moving between the locked and unlocked positions. Thus, the reinforcing member 150 can limit the movement of the fastener 131 during its radial movement, preventing it from lifting up during movement, thereby improving the overall smoothness and reliability of the fastener 131's movement.

[0115] like Figure 19 As shown, the fastening member 131 may include an upper locking portion 157, a lower locking portion 158, and a connecting portion 159. The lower locking portion 158 is located below the upper locking portion 157, and the connecting portion 159 connects the radially outer ends of both the upper locking portion 157 and the lower locking portion 158 to form the aforementioned clamping opening facing the center of the cover 110. The upper locking portion 157 is located above the outer periphery of the inner cover assembly 113 and abuts against the outer periphery of the inner cover assembly 113. The upper locking portion 157 is located below the pot opening portion 101a and abuts against the pot opening portion 101a in the locked position. The guide connecting member 137 is connected to the upper locking portion 157, thereby the connection position P is located at the upper locking portion 157. The reinforcing member 150 abuts against the radially inner end 156 of the upper locking portion 157.

[0116] The mounting surfaces of the fastener 131 and the reinforcing member 150 have a height difference to allow for the provision of their respective mounting structures. To eliminate the gap caused by the height difference, at least one of the locking portion 157 and the reinforcing member 150 is provided with a protrusion 160. The locking portion 157 abuts against the reinforcing member 150 via the protrusion 160. By providing the protrusion 160, the gap between the locking portion 157 and the reinforcing member 150 is reduced, allowing the fastener 131 and the reinforcing member 150 to abut against each other, at least when pressed, without changing their respective mounting surfaces.

[0117] In the illustrated example, both the upper locking portion 157 and the reinforcing member 150 are provided with protrusions 160. Specifically, the radially inner end 156 of the upper locking portion 157 is provided with an upwardly protruding first protrusion 161, and the reinforcing member 150 is provided with a downwardly protruding second protrusion 162. The second protrusion 162 is located below the first protrusion 161 and can abut against the first protrusion 161. The mounting surfaces of the fastening member 131 and the reinforcing member 150 can have a certain height difference, which facilitates the setting of the respective mounting structures of these two components, and further reduces the gap through the protrusions 160 on these two components, so that the reinforcing member 150 can limit the fastening member 131. Alternatively, the upper locking portion 157 is provided with an upwardly protruding protrusion 160, while the reinforcing member 150 is not provided with a protrusion 160; or the upper locking portion 157 is not provided with a protrusion 160, while the reinforcing member 150 is provided with a downwardly protruding protrusion 160.

[0118] For example, the fastening member 131 and / or the reinforcing member 150 are made of a sheet material and the protrusion 160 is formed by partial bending. This can enhance the structural strength of the associated components (upper locking portion 157 and / or reinforcing member 150) and prevent deformation of the component with the protrusion 160. Specifically, the first protrusion 161 is formed by partial bending, which can enhance the structural strength of the reinforcing member 150; the second protrusion 162 is formed by partial bending, which can enhance the structural strength of the fastening member 131.

[0119] The front-rear dimension D3 of the cover 110 is larger than its left-right dimension D2. The reinforcing member 150 can be an elongated strip extending along the front-rear dimension D3 of the cover 110, thus providing better reinforcement of the cover 110 in the front-rear dimension D3. The reinforcing members 150 are spaced apart along the left-right dimension D2 of the cover 110, and each reinforcing member 150 can extend through at least two fasteners 131. In a configuration where the reinforcing member 150 has a protrusion 160, the reinforcing member 150 has a protrusion 160 at each fastener 131. For example, the illustration shows four fasteners 131 and two reinforcing members 150, each reinforcing member 150 extending through two fasteners 131, and each reinforcing member 150 having two first protrusions 161. Alternatively, when two fasteners 131 are provided, each reinforcing member 150 extends through one fastener 131. Alternatively, when six fasteners 131 are provided, each reinforcement 150 may extend through three fasteners 131 if needed and / or desired. One reinforcement 150 simultaneously limits two or more fasteners 131, which reduces the number of reinforcements 150 and improves the installation efficiency of the cover due to the reduced number of parts.

[0120] The fastener 131 is located on the lower side of the cover 112, and the reinforcing member 150 is fixed to the cover 112 from the upper side. The reinforcing member 150 is located on the lower side of the rotating frame 132. The reinforcing member 150 can better separate the rotating frame 132 and the fastener 131, preventing interference between the rotating frame 132 and the fastener. Figure 20 and Figure 21 As shown, the cover 112 has a mounting opening 152 and a clearance opening 153 at positions corresponding to the fastener 131. The guide connector 137 can be connected to the fastener 131 via the mounting opening 152. The radially inner end 156 of the fastener 131 can abut against the reinforcement 150 via the clearance opening 153 (see...). Figure 18 The radially inner end 156 of the fastener 131 extends from the relief opening 153 so that the reinforcement 150 can simultaneously provide anti-deformation force to the cover 112 from above and provide downward pressure to the radially inner end 156 of the fastener 131.

[0121] The cover 112 may have a slot 154 at its front end and mounting posts 155 at its middle and rear ends. The front end of the reinforcing member 150 is inserted into the slot 154, and the middle and rear ends of the reinforcing member 150 are fixed to the mounting posts 155. For example, the reinforcing member 150 can be fixed to the mounting posts 155 with fasteners such as screws. The installation of the reinforcing member 150 is simple and easy to perform through the slot 154 and mounting posts 155 on the cover 112. The reinforcing member 150 and the cover 112 are also provided with through holes to facilitate the passage of the float device 136 and the upper temperature measuring device.
