[0003] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section 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.

[0004] To at least partially solve the above problems, this application provides a cooking appliance, the cooking appliance comprising:

[0005] The pot body has a snap-fit ​​edge;

[0006] The lid includes an inner lid that can be opened and closed and is disposed in the pot body, forming a cooking space between the inner lid and the pot body;

[0007] A fastening element having a clamping opening for clamping the fastening edge and the lid, the fastening element being movable between a locked position (locking the pot body and the lid) and an unlocked position (unlocking the pot body and the lid), the fastening element including a first fastening portion that abuts against the inner lid; and

[0008] A pushing structure is provided on the cover and / or the fastening member. When the inside of the cooking space is pressed up, the fastening member is in the locked position. The pushing structure acts on the first fastening part and drives the fastening member to rotate to the pressing state where the clamping opening is inclined towards the inside of the cooking space.

[0009] According to the cooking appliance of this application, when pressed up, the fastener is in the locked position, the pushing structure acts on the first fastening part, and drives the fastener to rotate to the pressing state in which the clamping opening is inclined towards the inside of the cooking space, so as to prevent or avoid the fastener from disengaging in the locked position and moving towards the unlocked position.

[0010] Optionally, the inner cover includes a first rib protruding toward the first engaging portion, and the pushing structure includes the first rib.

[0011] According to this application, by providing a first rib on the inner cover, the structural strength of the inner cover can be improved while reducing or preventing the inner cover from disengaging from the fastener under pressure, so as to reduce or prevent the inner cover from deforming due to force.

[0012] Optionally, the inner cover includes a plurality of first ribs, each of the first ribs being spaced apart in the circumferential direction of the inner cover and corresponding to the fastening member.

[0013] According to this application, by providing a plurality of first ribs on the inner cover, and arranging each first rib at intervals in the circumferential direction, the structural strength of the part of the inner cover used for contacting the fastener can be improved.

[0014] Optionally, the first rib extends continuously along the circumferential direction of the inner cover.

[0015] According to this application, by continuously providing the first rib along the circumferential direction in the inner cover, the integrity of the first rib in the inner cover can be improved, thereby helping to improve the overall structural strength of the inner cover and thus better preventing or avoiding deformation of the inner cover.

[0016] Optionally, the first fastening portion includes a root region, a middle region, and a free end region. The middle region connects the root region and the free end region. The root region is located on the side of the middle region away from the center of the inner cover. The first rib can abut against the root region.

[0017] According to this application, the first fastening portion is divided into a root region, a middle region, and a free end region, with the root region located on the side of the middle region away from the center of the inner cover. When the fastener is in the locked position and the cooking space is pressed upward, the first rib of the inner cover abuts against the root region, causing the root region to rise relative to the free end region. At this time, the abutting force of the first rib on the fastener has a component force along the path close to the center of the inner cover, and the fastener and the inner cover cooperate to form a self-locking mechanism, thereby preventing the fastener from disengaging from the inner cover.

[0018] Optionally, the first fastening portion includes a second rib protruding toward the inner cover, and the pushing structure includes the second rib.

[0019] According to this application, by providing a second rib in the first fastening part, the structural strength of the first fastening part can be improved while reducing or preventing the first fastening part from disengaging from the inner cover under pressure, so as to reduce or prevent the deformation of the first fastening part due to force.

[0020] Optionally, one of the inner cover and the first fastening portion includes a load-bearing boss, and the other of the inner cover and the first fastening portion includes a load-bearing recess adapted to accommodate the load-bearing boss.

[0021] The load-bearing boss and the load-bearing groove together constitute the pushing structure.

[0022] According to this application, by providing a load-bearing boss in one of the inner cover and a load-bearing groove in the other, it is possible to reduce or avoid the inner cover from disengaging from the fastener under pressure, while also improving the structural strength of the inner cover and the fastener, so as to reduce or avoid the deformation of the inner cover and the fastener due to force.

[0023] Optionally, the cover includes a liner disposed above the inner cover and a reinforcing member connected to the liner. The reinforcing member is disposed above the free end of the first fastening portion to restrict the upward movement of the fastening member.

[0024] According to this application, by providing a reinforcing member on the cover, with the reinforcing member positioned above the fastening member, the reinforcing member can abut against the upward-moving fastening member under pressure, thereby restricting the upward movement of the fastening member. Moreover, compared to using the cover to directly bear the force on the fastening member, this method only requires providing a reinforcing member at the position corresponding to the fastening member to increase local structural strength and load-bearing capacity, which helps to reduce the cost of the cover.

[0025] Optionally, the reinforcing member includes a third rib protruding toward the first fastening portion, the third rib being able to abut against the first fastening portion.

[0026] According to this application, by providing a third rib on the reinforcing member to abut against the first fastening part, the structural strength of the reinforcing member can be improved, thereby reducing or avoiding deformation caused by the force of the fastening part.

[0027] Optionally, the first fastening part includes a fourth protruding rib protruding toward the reinforcing member. When the fastening member is in the locked position, the third protruding rib and the fourth protruding rib are arranged correspondingly in the thickness direction of the cover.

[0028] According to this application, by providing a fourth rib for abutting the third rib in the first fastening part, the structural strength of the reinforcing member can be improved, and the structural strength of the part of the first fastening part used to abut the reinforcing member can be improved, thereby reducing or avoiding deformation of the fastening member.

[0029] Optionally, the first fastening part includes a fourth protruding rib protruding toward the reinforcing member. When the fastening member is in the locked position, the fourth protruding rib and the reinforcing member are arranged correspondingly in the thickness direction.

[0030] According to this application, by providing a fourth rib on the first fastening part of the fastening member to abut against the reinforcing member when pressed, the structural strength of the first fastening part can be improved, thereby reducing or avoiding deformation due to the reaction force of the reinforcing member.

[0031] Optionally, the cooking appliance further includes:

[0032] Guide connector, the guide connector being connected to the fastening member; and

[0033] A rotating frame is rotatably connected to the cover about a first axis. The rotating frame includes a guide hole adapted to pass through the guide connector. When the rotating frame rotates, it drives the guide connector to move along the extension direction of the guide hole, thereby driving the fastening member to move between a locked position and an unlocked position. The rotating frame is located above the reinforcing member.

[0034] According to this application, by providing a guide connector and a rotating frame, and by providing a guide hole on the rotating frame that is adapted to the guide connector, the fastening element is moved between the locked position and the unlocked position while the rotating frame rotates. Since the rotating frame is above the reinforcing member, it can better separate the rotating frame and the fastening element, preventing interference between them. Attached Figure Description

[0090] The terms “parallel” / “perpendicular” and similar expressions used in this application include absolute parallel / perpendicular relationships and approximately parallel / perpendicular relationships (e.g., relationships that differ from absolute parallel / perpendicular relationships by a range of -5° to +5°), and have equivalent effects.

[0091] The specific embodiments of this application will be described in more detail below with reference to the accompanying drawings, which illustrate representative embodiments of this application and are not intended to limit this application.

[0092] like Figures 1 to 18 As shown, this application provides a cooking appliance. The cooking appliance of this application can be an electric pressure cooker, electric slow cooker, electric hot pot, soy milk maker, blender, or other electric cooking appliances. The cooking appliance may include a cooker body 100, a lid 110, a position detection device 140, a drive motor 134, and a control circuit board 116.

[0093] 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.

[0094] See Figure 2 The pot body 100 includes a pot inner 101, a middle frame 102, a heating device (not shown), a base, and a temperature detection device (not shown). The pot inner 101, used for holding food, is removably installed in the pot body 100. The middle frame 102 can be referred to as a heat insulation cover. The middle frame 102 is located between the outer circumferential side of the pot inner 101 and the base 103 and is fixed to the base 103, suitable for positioning the pot inner 101 and also serving a heat insulation function. 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 is located below the pot inner 101 to heat the pot inner 101.

[0095] The control circuit board 116 includes a control unit, a digital display device, and circuitry. The control unit, for example, can be a microcontroller unit (MCU) used to control the cooking process of the cooking appliance. Figure 2 As shown, the control circuit board 116 can be installed in the cover 110.

[0096] A temperature detection device is used to detect the temperature of the cooking space or related to the cooking space. The temperature detection device includes a bottom temperature detection device and a top temperature detection device. The bottom temperature detection device is located, for example, at the bottom or side of the pot body, to detect the temperature of the bottom of the pot or indirectly the bottom of the cooking space. The top temperature detection device is located, for example, at the lid body, to detect the temperature of the top of the cooking space. Both the heating element and the temperature detection device are electrically connected to the control unit. The temperature detection device feeds back the sensed temperature information to the control unit, allowing the control unit to perform more precise control of, for example, the heating element, based on the temperature information.

[0097] See Figures 1 to 4 ,as well as Figure 5 and Figure 6 One end of the lid 110 in the front-rear direction D1 is rotatably connected to the pot body 100 via a pivot shaft about the rotation axis AX. An opening torsion spring 104 is mounted on the pivot shaft. Both ends of the opening torsion spring 104 abut against the lid 110 and the pot body 100 respectively, allowing the opening torsion spring 104 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 opening torsion spring 104 and rotates about the pivot shaft. The other end of the lid 110 in the front-rear direction D1 is detachably connected to the pot body 100 via a lid-closing hook 160.

[0098] See Figures 2 to 4The lid 110 includes a top cover 111, a liner 112, and an inner cover 113. In addition, the lid 110 may also include electrical components, valve components, etc. Therefore, the assembly of the top cover 111, liner 112, and inner cover 113 can also be referred to as the lid body 117. It is understood that the lid body 117 may only have the degree of freedom to rotate about the axis of rotation AX relative to the cookware body 100. The top cover 111 is located at the outermost (i.e., uppermost) side of the lid 110, forming the outer shell of the lid 110. The top cover 111 may include a top cover body 111a and a panel 111b. The liner 112 is disposed below the top cover 111 and connected to the top cover 111. For example, the liner 112 can be connected to the top cover 111 via fasteners, snap-fit ​​connectors, etc. The liner 112 is mainly used to centrally mount various functional components of the lid 110 that sense and control the working status of the pressure cooking appliance, such as sensors. The inner cover 113 is located at the innermost (i.e., lowest) side of the cover body 110 and is positioned below the liner 112. The inner cover 113 is detachably connected to the liner 112 via a snap-fit ​​or other detachable connector for easy cleaning and replacement; here, the inner cover 113 can be referred to as a removable cover. The inner cover 113 is positioned facing the cooking space. That is, when the cover body 110 is closed on the pot body 100, the inner cover 113 is positioned directly above the cooking space. Furthermore, an inner cover sealing ring 1131 is provided on the outer periphery of the inner cover 113. The inner cover sealing ring 1131 is used to seal the gap between the inner cover 113 and the pot body 101 when the inner cover 113 is closed with the pot body 101.

[0099] See Figure 4 The cover 110 is equipped with a steam valve 114 and an electric pressure relief device 120. The steam valve 114 has a steam vent (not shown in the figure) that communicates with the outside environment. A steam passage 110a, communicating with the steam valve 114, is also provided inside the cover 110. The cooking space is connected to the external environment through the steam passage 110a and the steam valve 114. The external environment refers to the environment outside the pressure cooking appliance. In this application, the steam valve 114 is used to connect the cooking space to the external environment to release steam generated during cooking. The electric pressure relief device 120 is electrically connected to a control unit and is controlled to switch between an open state (open steam passage 110a) and a closed state (closed steam passage 110a).

[0100] To reduce heat loss during cooking, the pot body 100 includes the aforementioned heat-insulating cover, such as... Figure 2 As shown. In this design, the fastening element 131 can engage with the edge of the inner pot 101 or the edge of the insulation cover. For example, in a rice cooker, the fastening element 131 can engage with the edge of the inner pot 101. For example, in an electric pressure cooker, the edge of the insulation cover is at least partially exposed, and the fastening element 131 can engage with the edge of the insulation cover. For ease of explanation, the following description will focus on the example of the fastening element 131 engaging with the edge of the inner pot 101.

[0101] See Figures 2 to 6 The cooking appliance may also include a locking / unlocking assembly 130 and a power source. The locking / unlocking assembly 130 is connected to the power source to switch between a locked state and an unlocked state under the drive of the power source. In the locked state, the locking / unlocking assembly 130 prevents the inner cover 113 of the lid 110 from separating from the inner pot 101. In the unlocked state, the locking / unlocking assembly 130 allows the inner cover 113 to separate from the inner pot 101. The inner cover 113 has a radial direction and an axial direction. The radial direction is the radial direction of a circle about the geometric center of the inner cover 113. The axial direction is the direction passing through the geometric center of the inner cover 113 and parallel to the thickness direction of the inner cover. Here, the geometric center of the inner cover 113, in the example where the inner cover is circular, is the exact center of the inner cover or the center of the circle. The locking / unlocking assembly 130 includes a fastening element 131. The fastening member 131 is movably connected to the cover body 110 in a locked position and an unlocked position along the radial direction of the inner cover 113. The locking and unlocking assembly 130 is locked when the fastening member 131 is in the locked position. The locking and unlocking assembly 130 is unlocked when the fastening member 131 is in the unlocked position. The fastening member 131 may include a clamping opening for receiving the edge of the inner pot 101 and the edge of the inner cover 113. When the fastening member 131 is in the locked position, the edge of the inner pot 101 and the edge of the inner cover 113 are clamped in the clamping opening to limit the inner pot 101 and the inner cover 113 in the height direction D3 of the pressure cooking appliance, thereby preventing the inner pot 101 and the inner cover 113 from disengaging from each other, thus ensuring that the cooking space can be pressurized. When the fastening member 131 is in the unlocked position, the clamping opening disengages from at least one of the edges of the inner pot 101 and the inner cover 113. Preferably, the fastening member 131 in the unlocked position disengages from the inner pot 101. The power source can be a drive motor 134. The drive motor 134 is driven to the fastening member 131. The drive motor 134 is connected to a control unit to drive the fastening member 131 to move between a locked position and an unlocked position under the control of the control unit. According to this application, by actuating the fastening member 131 between the locked and unlocked positions by the drive motor 134, the connection state between the fastening member 131 and the inner cover 113 and the pot liner 101 can be changed. When the fastening member 131 is in the locked position, it can prevent the inner cover 113 and the pot liner 101 from separating, so that the pot liner 101, the inner cover 113, and the fastening member 131 can share the pressure. When the fastening member 131 is in the unlocked position, it can allow the inner cover 113 to separate from the pot liner 101, thereby facilitating the opening of the lid 110.

[0102] See Figures 2 to 8Furthermore, the cover opening assembly 130 may also include a rotating frame 132. The rotating frame 132 is rotatably connected to the cover body 110 about a first axis AX1. The rotating frame 132 may include a guide hole 132a. The extension trajectory of the guide hole 132a intersects the radial direction of the inner cover 113. The extension trajectory may be a straight line, a curve, or a combination of both. The extension trajectory has at least a portion inclined to the radial direction of the inner cover 113, thereby enabling the drive fastener 131 to move in the radial direction of the inner cover 113. The fastener 131 is movably connected to the guide hole 132a. The rotating frame 132 is driveably connected to the drive motor 134. According to this application, by providing the rotating frame 132 between the drive motor 134 and the fastener 131, the power of the drive motor 134 is transmitted to the fastener 131 through the rotating frame 132, thereby driving the fastener 131 to move by rotating the rotating frame 132. During the process of the drive motor 134 driving the rotating frame 132 to rotate, the fastening member 131 slides relative to the rotating frame 132 along the extension trajectory of the guide hole 132a, thereby enabling the drive fastening member 131 to move between the locked position and the unlocked position.

[0103] See Figures 3 to 6 Optionally, the fastening member 131 is connected to the guide hole 132a via a guide connector 137. The guide connector 137 is connected to the fastening member 131. The guide connector 137 is located in the guide hole 132a and is movable relative to the guide hole 132a. During the rotation of the rotating frame 132, the fastening member 131 slides relative to the rotating frame 132 along the extension direction of the guide hole 132a through the sliding engagement of the guide connector 137 and the guide hole 132a, thereby causing the fastening member 131 to be driven by the rotating frame 132 to move in the radial direction of the inner cover 113.

[0104] See Figure 17 and Figure 18Exemplarily, the cover 112 is provided with a guide cavity 112a. A fastener 131 is slidably mounted on the guide cavity 112a. The guide cavity 112a may be configured as a groove recessed upward from the lower surface of the cover 112. The cover 112 also has a guide hole 112b communicating with the guide cavity 112a. A guide connector 137 passes through the guide hole 112b. The guide connector 137 includes a stud 137c, a screw 137a, and a sleeve 137b. The stud 137c is connected to the top of the fastener 131. The stud 137c passes through the guide hole 112b and the guide hole 132a and is connected to the screw. The sleeve 137b is fitted over the stud 137c to reduce friction between the stud 137c and the cover 112 and the rotating frame 132. The guide cavity 112a and guide hole 112b can extend radially about the first axis AX1. The fastening member 131 may include a first fastening portion 131b, a second fastening portion 131c, and a connecting portion 131d. The connecting portion 131d connects between the first fastening portion 131b and the second fastening portion 131c. Specifically, both ends of the connecting portion 131d are connected to the respective ends of the first fastening portion 131b and the second fastening portion 131c that are away from the cooking space. The first fastening portion 131b, the second fastening portion 131c, and the connecting portion 131d together form a clamping opening facing the first axis AX1. The clamping opening is used to accommodate the edge of the inner lid 113 and the edge of the pot liner 101. The first fastening portion 131b is used to restrict the upward movement of the inner lid 113 when pressed against the cooking space. The second fastening portion 131c is used to restrict the downward movement of the pot liner 101 when pressed against the cooking space. In the radial direction of the inner cover 113, the first fastening portion 131b is longer than the second fastening portion 131c. Furthermore, at least the end of the first fastening portion 131b remote from the connecting portion 131d is located directly above the inner cover 113, thereby preventing the fastening member 131 from jamming with the inner cover during movement towards the locked position. When the cover 110 is closed onto the pot body 100, the second fastening portion 131c is aligned with the lower edge of the inner pot 101 to prevent the fastening member 131 from jamming with the edge of the inner pot 101 during movement towards the locked position.

[0105] See Figures 2 to 7 ,as well as Figure 10Furthermore, the cover-opening assembly 130 may also include a drive transmission assembly. The drive transmission assembly is connected between the rotating frame 132 and the motor shaft 134a of the drive motor 134 to transmit power that causes the rotating frame 132 to rotate. The drive transmission assembly includes a transmission connector 133. The transmission connector 133 has opposing driving ends 133a and driven ends 133b. The driving end serves as the rotation center. The driving end 133a is rotatably connected to the cover 110 about a second axis AX2. The driving end 133a is connected to the motor shaft 134a of the drive motor 134 to rotate synchronously with the motor shaft 134a. The driven end 133b is movably connected to the rotating frame 132. The second axis AX2 is parallel to the first axis AX1. During the rotation of the motor shaft 134a of the drive motor 134, the transmission connector 133 rotates in the same direction as the motor shaft 134a of the drive motor 134. During the rotation of the motor shaft 134a of the drive motor 134, the rotation direction of the transmission connector 133 is opposite to the rotation direction of the rotating frame 132. For example... Figure 5 and Figure 6 As shown, the transmission connector 133 and the motor shaft 134a have a first rotation direction R1 and a second rotation direction R2. The first rotation direction R1 and the second rotation direction R2 are opposite. The first rotation direction R1 can be understood as counterclockwise. Correspondingly, the second rotation direction R2 can be understood as clockwise. During the rotation of the transmission connector 133 along the motor shaft 134a 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 connector 133 along the motor shaft 134a 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. According to this application, by adding a transmission connector 133 between the drive motor 134 and the rotating frame 132, the power of the drive motor 134 is transmitted to the rotating frame 132 through the transmission connector 133, thereby facilitating the reasonable arrangement of the positions of the rotating frame 132 and the drive motor 134.

[0106] See Figure 3 , Figures 5 to 8Optionally, the rotating frame 132 is provided with a trigger portion 132c. The position detection device 140 includes a locking position detection device 141 corresponding to the locking position and an unlocking position detection device 142 corresponding to the unlocking position. The locking position detection device 141 is used to detect the locking position signal. The unlocking position detection device 142 is used to detect the unlocking position signal. Optionally, the locking position detection device 141 is located on one side of the trigger portion 132c in the circumferential direction around the first axis AX1. The unlocking position detection device 142 is located on the other side of the trigger portion 132c in the circumferential direction around the first axis AX1. The trigger portion 132c is protrudingly provided on the edge of the rotating frame 132. The drive motor 134 can drive the transmission connecting member 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 position shown in the figure. Figure 5 The third extreme position is shown, which causes the fastener 131 to move to the unlocked position. When the rotating frame 132 rotates to the third extreme position, the trigger part 132c on the rotating frame 132 is detected by the unlocked position detection device 142, thereby generating an unlocked position signal and sending it to the control unit. The control unit determines that the fastener 131 is in the unlocked position based on the unlocked position signal. The drive motor 134 can drive the transmission connector 133 to rotate along the first rotation direction R1 to the second extreme position P2, thereby causing the rotating frame 132 to rotate to the third extreme position. Figure 6 The fourth extreme position, as shown, causes the fastener 131 to move to the locked position. When the rotating frame 132 rotates to the fourth extreme position, the trigger part 132c on the rotating frame 132 is detected by the locking position detection device 141, thereby generating a locking position signal and sending it to the control unit. The control unit determines that the fastener 131 is in the locked position based on the locking position signal.

[0107] See Figures 2 to 8 Furthermore, the rotating frame 132 has a transmission hole 132e. The transmission connector 133 also has a connecting shaft 133c. The connecting shaft 133c is inserted into the transmission hole 132e. The transmission hole 132e provides allowance for the connecting shaft 133c to move radially relative to the rotating frame 132. For example, the transmission hole 132e can be configured as an elongated hole extending radially in a circle centered on the first axis AX1, to allow the connecting shaft 133c to move within the transmission hole 132e, thereby preventing jamming of the rotation of the rotating frame 132 and the rotation of the transmission connector 133. The transmission hole 132e can be a through hole or a blind hole. The transmission hole 132e is located at the edge of the rotating frame 132. While the connecting shaft 133c drives the rotating frame 132 to rotate, it can slide or move within the transmission hole 132e along its length. The transmission hole 132e and the aforementioned trigger portion 132c are arranged at intervals in the circumferential direction around the first axis AX1.

[0108] It is understandable that in other examples, the positions of the transmission hole and the connecting shaft can be interchanged; that is, the transmission hole can be set in the transmission connector, and the connecting shaft can be set in the rotating frame.

[0109] See Figure 3 , Figures 5 to 8 Furthermore, the rotating frame 132 also includes a drive boss 132d. The drive boss 132d has an engaged state that engages with the lid latch 160 and a disengaged state that disengages from the lid latch 160. In the engaged state, the drive boss 132d prevents external force from successfully pressing the lid opening button (not shown), thereby preventing the lid 110 from being opened. In the disengaged state, the drive boss 132d allows external force to successfully press the lid opening button, thereby allowing the lid 110 to be opened under the elastic force of the lid opening torsion spring 104. Specifically, when the lid 110 is closed on the pot body 100, when the rotating frame 132 rotates in the second rotation direction R2 (the motor shaft 134a rotates in the first rotation direction R1) to such a state... Figure 6 At the fourth extreme position shown, the fastener 131 moves to the locked position, and the transmission boss 132d engages with the lid hook 160. With the lid 110 closed on the pot body 100, when the rotating frame 132 rotates along the first rotation direction R1 (the motor shaft 134a rotates in the second rotation direction R2) to the position shown... Figure 5 At the third extreme position shown, the fastener 131 moves to the unlocked position, and the transmission boss 132d separates from the cover hook 160. It should be noted that the rotating bracket 132 rotates freely. Figure 5 Rotate to the third extreme position as shown Figure 6 The angle of the fourth extreme position shown is less than or equal to the central angle of the circle centered on the first axis AX1 corresponding to the guide hole 132a. The central angle of the circle centered on the first axis AX1 corresponding to the transmission boss 132d can be less than or equal to the central angle corresponding to the guide hole 132a.

[0110] Continue reading Figure 3 , Figures 5 to 8 Optionally, the cover 112 has a float mounting hole (not shown). A float component 136 is installed in the float mounting hole. A rotating frame 132 is located between the cover 112 and the top cover 111. The rotating frame 132 has a limiting hole 132b. When the fastener 131 is in the locked position, the limiting hole 132b and the float mounting hole are aligned. When the cooking space is pressed up, the float component 136 moves upward and inserts into the limiting hole 132b. At this time, the float component 136 is connected to the float mounting hole and the limiting hole 132b, which can prevent the rotating frame 132 from rotating. This prevents the rotating frame 132 from rotating when the cooking space is pressed up. When the cooking space is under normal pressure, the float component 136 disengages from the limiting hole 132b. At this time, the rotating frame 132 can rotate relative to the cover 112.

[0111] See below for further information. Figures 1 to 18 The cooking appliance of the embodiments of this application will be further explained. The following will describe the pushing structure between the fastening edge of the pot body 100 and the lid 110, and will focus on the pushing structure between the fastening member 131 and the inner lid 113, which is used to reduce or prevent the fastening member 131 from disengaging from the inner lid 113 under pressure.

[0112] According to an embodiment of this application, the cooking appliance has a fastening member 131 with a clamping opening for clamping the fastening edge of the pot body 100 and the inner cover 113 of the lid 110. The fastening member 131 is movable between a locked position that locks the pot body 100 and the lid 110 and an unlocked position that unlocks the pot body 100 and the lid 110. The fastening member 131 includes a first fastening portion 131b that abuts against the inner cover 113. The cooking appliance also includes a pushing structure. The pushing structure is disposed on the lid 110 and / or the fastening member 131. When the interior of the cooking space is pressed up, the fastening member 131 is in the locked position, the pushing structure acts on the first fastening portion 131b, and drives the fastening member 131 to rotate to an upward pressing state in which the clamping opening is inclined toward the interior of the cooking space. In other words, when the fastener 131 is in the locked position and the internal air pressure of the cooking space rises, the first fastening portion 131b and the second fastening portion 131c of the fastener 131 respectively abut against the inner cover 113 and the fastening edge. The pushing structure abuts against the first fastening portion 131b due to the increased air pressure, and the fastener 131 is under force, with the clamping opening tilted towards the geometric center of the cooking space, as... Figure 12 The fastener 131 shown can rotate counterclockwise. That is, the clamping opening of the fastener 131 is tilted downward, and the side of the fastener 131 away from the first axis AX1 is tilted upward. In this way, when the air pressure in the cooking space rises or when there are other external disturbances, the fastener 131 will not easily slide to the unlocked position, thus ensuring the locked state of the lid 110 and the inner pot 101.

[0113] See Figure 2 , Figures 9 to 16For example, the inner pot 101 has a first outer periphery. The first outer periphery can be understood as the outward flange of the pot opening of the inner pot 101, and the first outer periphery can serve as a fastening edge. The inner cover 113 has a second outer periphery 113a. The fastening member 131 includes a first fastening portion 131b. The first fastening portion 131b is connected to the lower part of the guide connector 137 so that the fastening member 131 can move between a locked position and an unlocked position along a guide direction. Here, the guide direction can be the radial direction of a circle centered on a first axis AX1. The fastening member 131 in the locked position fastens to the lower part of the first outer periphery and the upper part of the second outer periphery 113a. Specifically, the first fastening portion 131b fastens to the upper part of the second outer periphery 113a. The second fastening portion 131c fastens to the lower part of the first outer periphery. The first fastening portion 131b has a root end and a free end. The root end and the free end are located on both sides of the guide connector 137 along the guide direction. The root end is closer to the geometric center of the inner cover 113 than the free end. The first engaging portion 131b is located between the liner 112 and the inner cover 113 along the thickness direction of the cover body 110. At least one of the first engaging portion 131b and the second outer periphery 113a of the inner cover 113 is provided with a pushing structure suitable for abutting each other along the thickness direction. When the engaging member 131 is in the locked position, the pushing structure is located radially between the guide connector 137 and the root end.

[0114] According to this application, at least one of the first engaging portion 131b and the second outer periphery 113a of the inner cover 113 is provided with a load-bearing structure, which corresponds to the position between the guide connector 137 and the connecting portion 131d when the engaging member 131 is in the locked position. When pressed up, the inner cover 113 is subjected to an upward pressure. Since the inner cover 113 and the engaging member 131 are in contact with each other through the load-bearing structure, the inner cover 113 and the engaging member 131 transmit force through the load-bearing structure, thereby causing the engaging member 131 to flip, which in turn causes the end of the first engaging portion 131b near the connecting portion 131d to move upward and the end of the first engaging portion 131b away from the connecting portion 131d to move downward, thereby preventing or avoiding the inner cover 113 from disengaging from the engaging member 131.

[0115] In such Figure 10 and Figure 13 In some of the examples shown, the inner cover 113 includes a first rib 113b that protrudes toward the first engaging portion 131b. The push structure includes the first rib 113b.

[0116] According to this application, by providing a first rib 113b in the inner cover 113, when the internal air pressure of the cooking space rises, the first fastening part 131b abuts against the first rib 113b. A gap exists between the first fastening part 131b and other areas of the inner cover 113, thereby allowing the end of the fastener 131 furthest from the cooking space to flip upwards, with the clamping opening facing the center area of ​​the cooking space. This reduces or prevents the inner cover 113 from disengaging from the fastener 131 under pressure, while also improving the structural strength of the inner cover 113, thus reducing or preventing deformation of the inner cover 113 due to stress.

[0117] Optionally, the inner cover 113 includes a plurality of first protrusions 113b. Each of the first protrusions 113b is spaced apart in the circumferential direction of the inner cover 113 and is arranged in a one-to-one correspondence with the fastening member 131.

[0118] According to this application, by providing a plurality of first ribs 113b in the inner cover 113, and arranging each first rib 113b at intervals in the circumferential direction, the structural strength of the portion of the inner cover 113 used for contacting the fastener 131 can be improved.

[0119] Optionally, the first rib 113b extends continuously along the circumferential direction of the inner cover 113.

[0120] According to this application, by continuously providing the first rib 113b along the circumferential direction in the inner cover 113, the integrity of the first rib 113b in the inner cover 113 can be improved, thereby helping to improve the overall structural strength of the inner cover 113 and thus better preventing or avoiding deformation of the inner cover 113.

[0121] Exemplarily, the first engaging portion 131b includes a root region, a middle region, and a free end region. The middle region connects to the root region and the free end region in the radial direction. The root region is located on the side of the middle region away from the center of the inner cover 113. That is, the root region, the middle region, and the free end region can be arranged sequentially in the radial direction toward the center of the inner cover 113. The first rib 113b can abut against the root region when the engaging member 131 is in the locked position and the cooking space is pressed up.

[0122] According to this application, the first engaging portion 131b is divided into a root region, a middle region, and a free end region, with the root region located on the side of the middle region away from the center of the inner cover 113. When the engaging member 131 is in the locked position and the cooking space is pressed upward, the first rib 113b of the inner cover 113 abuts against the root region, causing the root region to rise relative to the free end region. At this time, the abutting force of the first rib 113b on the engaging member 131 has a component force along the path close to the center of the inner cover 113, and the engaging member 131 and the inner cover 113 cooperate to form a self-locking mechanism, thereby preventing the engaging member 131 from disengaging from the inner cover 113.

[0123] Optionally, the guide connector 137 is connected to the intermediate region. The root region corresponds to the region of the first engaging portion 131b located between the guide connector 137 and the connecting portion 131d. The free end region corresponds to the region of the first engaging portion 131b located between the guide connector 137 and the free end.

[0124] In other examples not shown, various structures can be used to replace the first protruding rib of the inner cover 113. For example, the pushing structure can be a telescopic member. The telescopic member can push the fastener 131 from below when it is pressed up, so that the clamping opening of the fastener 131 is tilted downward towards the cooking space when pressed up. Alternatively, the pushing structure can be a lever connected to the float member 136. Here, utilizing the principle that the float member 136 floats up when pressed up, a lever is provided above the fastener 131. One end of the lever is connected to the float member 136, and the other end is located above the free end of the fastener 131. When the float member 136 is pressed up, it floats up and pushes the other end of the lever down, pressing down the first fastening part 131b, causing the free end of the fastener 131 to tilt downward relative to the root end, thus making it difficult for the fastener 131 to detach from the inner cover 113.

[0125] In such Figure 14 In other examples shown, the first engaging portion 131b includes a second rib 131b1 protruding toward the inner cover 113. The pushing structure includes the second rib.

[0126] According to this application, by providing a second rib 131b1 in the first fastening part 131b, the structural strength of the first fastening part 131b can be improved while reducing or preventing the first fastening part 131b from disengaging from the inner cover 113 under pressure, so as to reduce or prevent the first fastening part 131b from deforming due to force.

[0127] In such Figure 15 In some of the further examples shown, the second outer periphery 113a includes a first rib 113b protruding toward the first engaging portion 131b. The first engaging portion 131b includes a second rib 131b1 protruding toward the second outer periphery 113a. Along the radial direction of the inner cover 113, if the first rib 113b is closer to the first axis AX1, then the height of the first rib 113b is less than the height of the second rib 131b1, and vice versa. The first rib 113b and the second rib 131b1 together constitute a load-bearing structure.

[0128] According to this application, by providing a first rib 113b on the second outer periphery 113a of the inner cover 113 and a second rib 131b1 on the first fastening part 131b, the structural strength of the inner cover 113 and the fastening part 131 can be improved while reducing or preventing the inner cover 113 from disengaging from the fastening part 131 under pressure, so as to reduce or prevent the inner cover 113 and the fastening part 131 from deforming due to force.

[0129] In such Figure 16 In some of the further examples shown, one of the inner cover 113 and the first fastening portion 131b includes a load-bearing boss 113c. The other of the inner cover 113 and the first fastening portion 131b includes a load-bearing recess 131b2. The load-bearing recess 131b2 is adapted to receive the load-bearing boss 113c. The load-bearing boss 113c and the load-bearing recess 131b2 together constitute a pushing structure. In the figure, the load-bearing boss 113c is provided on the inner cover 113. Correspondingly, the load-bearing recess 131b2 is provided on the fastening member 131.

[0130] According to this application, by providing a load-bearing boss 113c on one of the inner cover 113 and a load-bearing groove 131b2 on the other, in the locked position, the load-bearing boss 113c is placed in the load-bearing groove 131b2, and there is a gap between the two in the axial direction of the inner cover 113. Under the pressure of the cooking space, the gap in the axial direction between the load-bearing boss 113c and the load-bearing groove 131b2 decreases, ultimately increasing the contact area between the load-bearing boss 113c and the load-bearing groove 131b2. This increases the friction between the inner cover 113 and the first fastening part 131b, and also provides a radial limiting effect through the cooperation of the load-bearing boss 113c and the load-bearing groove 131b2. Therefore, not only can the movement of the fastener 131 from the locked position to the unlocked position when it is pressed down can be reduced or avoided, but the structural strength of the inner cover 113 and the fastener 131 can also be improved, so as to reduce or avoid the deformation of the inner cover 113 and the fastener 131 due to force.

[0131] See Figures 9 to 12 For example, the cover 110 includes a liner 112 disposed above the inner cover 113 and a reinforcing member 118 connected to the liner 112. The reinforcing member 118 is disposed above the free end of the first fastening portion 131b to restrict the upward movement of the fastening member 131.

[0132] According to this application, by providing a reinforcing member 118 on the cover 112, and with the reinforcing member 118 positioned above the fastening member 131, the reinforcing member 118 can abut against the upwardly moving fastening member 131 under pressure, thereby restricting the upward movement of the fastening member 131. Moreover, compared to using the cover 112 to directly bear the force on the fastening member 131, this only requires providing the reinforcing member 118 at the position corresponding to the fastening member 131 to increase the local structural strength and load-bearing capacity, which helps to reduce the cost of the cover 110.

[0133] See Figures 9 to 12 In some examples, the reinforcement 118 includes a third rib 118a that protrudes toward the first engaging portion 131b. The third rib 118a abuts against the first engaging portion 131b. Optionally, when the cover opening assembly 130 is in the locked position, the third rib 118a is correspondingly arranged on the side of the guide connector 137 away from the connecting portion 131d.

[0134] According to this application, by providing a third rib 118a in the reinforcing member 118 to abut against the first fastening part 131b, the structural strength of the reinforcing member 118 can be improved, thereby reducing or avoiding deformation caused by the force of the fastening part 131.

[0135] See Figures 9 to 12 as well as Figure 18 Furthermore, the first engaging portion 131b includes a fourth rib 131b3 protruding toward the reinforcing member 118. When the engaging member 131 is in the locked position, the third rib 118a and the fourth rib 131b3 are arranged correspondingly in the thickness direction. When the cover opening assembly 130 is in the locked position, the third rib 118a and the fourth rib 131b3 are arranged correspondingly in the height direction of the cooking appliance.

[0136] According to this application, by providing a fourth rib 131b3 for abutting against the third rib 118a in the first fastening part 131b, the structural strength of the part of the first fastening part 131b used to abut against the reinforcing member 118 can be improved, thereby reducing or avoiding deformation of the fastening member 131.

[0137] In other examples, a rib structure is provided only in the first engaging portion 131. The first engaging portion 131b includes a fourth rib 131b3 protruding toward the reinforcing member 118. The fourth rib 131b3 is located on the side of the guide connector 137 away from the connecting portion. When the lid opening assembly 130 is in the locked position, the fourth rib 131b3 and the reinforcing member 118 are arranged correspondingly in the height direction of the cooking appliance.

[0138] According to this application, by providing a fourth protruding rib 131b3 on the first fastening part 131b of the fastening member 131 to abut against the reinforcing member 118 when pressed, the structural strength of the first fastening part 131b can be improved, thereby reducing or avoiding deformation due to the reaction force of the reinforcing member 118.

[0139] According to this application, by providing a guide connector 137 and a rotating frame 132, and by providing a guide hole 132a on the rotating frame 132 that is adapted to the guide connector 137, the fastening member 131 is moved between the locked position and the unlocked position while the rotating frame 132 rotates. Since the rotating frame 132 is above the reinforcing member 118, it can better separate the rotating frame 132 and the fastening member 131, preventing interference between the rotating frame 132 and the fastening member 131.
