Description

Technical Field

[0001] This application relates generally to the technical field of cookware, and more specifically to a cooking utensil. Background Technology

[0002] The cooking appliance in the related technology includes a pot body and a lid. The lid is detachably mounted on the pot body. The lid has a locking and unlocking mechanism for automatically engaging and disengaging with the pot body, and the locking and unlocking mechanism is switched in a electrically controlled manner. However, when the locking and unlocking mechanism locks the lid and pot body, if the transmission frame in the locking and unlocking mechanism deforms during use, the connecting parts may jam during the movement of the guide groove, resulting in the fastening parts not moving into place. Utility Model Content

[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] pot body;

[0006] A lid, which is foldably disposed on the pot body;

[0007] A fastening element, movably connected to the lid body between a locked position and an unlocked position, wherein the fastening element in the locked position locks the lid body and the pot body, and the fastening element in the unlocked position unlocks the lid body and the pot body; and

[0008] A rotating frame is movably connected to the cover. The rotating frame includes a guide hole movably connected to the fastener. The guide hole includes a positioning section and a driving section that communicate with each other. The positioning section is used to hold the fastener in the locked position or the unlocked position. The driving section is used to drive the fastener to move between the locked position and the unlocked position when the rotating frame moves. The width of the connection between the positioning section and the driving section is greater than the width of the positioning section and / or the driving section.

[0009] According to the cooking appliance of this application, during the movement of the rotating frame relative to the lid, the fastening element moves along the guide hole relative to the rotating frame. When the fastening element is in the driving section, it can move between the locked and unlocked positions with the movement of the rotating frame. When the fastening element is in the positioning section, it can be held in the locked or unlocked position. During the movement of the fastening element from the driving section to the positioning section or from the positioning section to the driving section, the width at the connection point is greater than the width of the driving section or the positioning section. This makes the movement of the fastening element smoother and prevents it from jamming at the junction of the two sections, which would prevent the fastening element from moving accurately into place.

[0010] Optionally, the rotating frame is rotatably connected to the cover about a first axis, the fastening member moves in a radial direction perpendicular to the first axis, the positioning section includes a cover locking section, the driving section has a locking end, the fastening member moved to the locking end is located in the locked position, the locking end is connected to the cover locking section, the cover locking section extends in a circumferential direction centered on the first axis, and when the fastening member is located in the cover locking section, the fastening member is held in the locked position.

[0011] According to this application, by rotating the frame to the cover and aligning the locking end of the drive section with the locking position, the fastener can reach the locking position when it moves to the locking end of the drive section as the frame rotates. The locking end is connected to the locking cover positioning section. After the frame rotates further, the fastener moves and abuts against the locking cover positioning section. The locking cover positioning section can restrict the fastener from moving radially toward the unlocking position, thereby keeping the fastener that has moved to the locking position in the locking position.

[0012] Optionally, the guide hole further includes an unlocking positioning section for holding the fastener in the unlocked position.

[0013] According to this application, an unlocking positioning segment is provided to keep the fastener in the unlocked position.

[0014] Optionally, the rotating frame is rotatably connected to the cover about a first axis, the fastening member moves in a radial direction perpendicular to the first axis, the driving section has an unlocking end, the fastening member moved to the unlocking end is located in the unlocking position, the unlocking end is connected to the unlocking positioning section, the unlocking positioning section extends in a circumferential direction centered on the first axis, and when the fastening member is located in the unlocking positioning section, the fastening member is held in the unlocking position.

[0015] According to this application, by rotating the frame and the cover, the unlocking end of the drive section corresponds to the unlocking position, so that the fastener moves with the rotation of the frame to the unlocking end of the drive section and reaches the unlocking position. The fastener is connected to the unlocking positioning section through the unlocking end, and the unlocking positioning section extends along the circumferential direction of the first axis. When the fastener moves to the unlocking position, the unlocking positioning section can restrict the fastener from moving in the radial direction, thereby keeping the fastener that has moved to the unlocking position in the unlocking position.

[0016] Optionally, the rotating frame is rotatably connected to the cover about a first axis.

[0017] The fastening element moves relative to the cover in a radial direction perpendicular to the first axis.

[0018] The drive segment has a locking end and an unlocking end. The fastener located in the locking position moves to the locking end, and the fastener located in the unlocking position moves to the unlocking end. The locking end and the unlocking end are spaced apart in a circumferential direction centered on the first axis. The dimension of the drive segment in the radial direction is equal to the distance the fastener moves between the locking position and the unlocking position. The distance between the locking end and the first axis is less than the distance between the unlocking end and the first axis.

[0019] According to this application, by rotating the rotating frame and connecting it to the cover, since the radial dimension of the drive section is equal to the distance the fastener moves between the locked and unlocked positions, the fastener can move to the locked position when it moves along the guide hole to the locking end during the rotation of the rotating frame, and can move to the unlocked position when it moves along the guide hole to the unlocked end.

[0020] Optionally, the extension trajectory of the drive segment is inclined to the line connecting any point of the drive segment and the first axis.

[0021] According to this application, the extension trajectory of the drive segment is inclined to the line connecting any point of the drive segment and the first axis, which simplifies the structure of the drive segment and facilitates design and manufacturing.

[0022] Optionally, the rotating frame includes a trigger.

[0023] The cooking appliance also includes a position detection device, which is triggered by the trigger when the fastener moves to the locked position and / or the unlocked position.

[0024] According to this application, by setting a trigger on the rotating frame and setting a position detection device, a position signal can be detected when the fastener moves to the locked position and / or the unlocked position, thereby determining that the fastener has moved into place.

[0025] Optionally, the rotating frame is rotatably connected to the cover about a first axis.

[0026] The trigger element is constructed as a protrusion extending outward from the edge of the rotating frame in a radial direction along the first axis.

[0027] The position detection device includes a locked position detection device and an unlocked position detection device, which are located at both ends of the stroke of the trigger as it rotates with the rotating frame.

[0028] According to this application, by setting the trigger as a protrusion extending outward in the radial direction from the edge of the rotating frame, and arranging a locking position detection device and an unlocking position detection device at both ends of the trigger's rotation stroke, it is possible to achieve the purpose of position detection while reducing the space occupied on the upper and / or lower sides of the rotating frame, and also helps to reduce the thickness of the cover.

[0029] Optionally, the guide hole includes an unlocking positioning section and a locking cover positioning section. The unlocking positioning section is used to hold the fastener in the unlocked position, and the locking cover positioning section is used to hold the fastener in the locked position. The position detection device includes a locked position detection device and an unlocking position detection device. Each of the locked position detection device and the unlocking position detection device is a micro switch. The moving distance of the trigger element from abutting the locked position detection device to triggering the locked position detection device is less than the length of the locking cover positioning section, and the moving distance of the trigger element from abutting the unlocking position detection device to triggering the unlocking position detection device is less than the length of the unlocking positioning section.

[0030] According to this application, when a micro switch is selected as the position detection device, the trigger element can activate the position detection device by abutting against it during the rotation of the rotating frame. The trigger element typically needs to move a certain distance from the moment it abuts against the micro switch. By setting the distance the trigger element needs to move to activate the locking position detection device to be less than the locking cover positioning section, more reliable activation of the locking position detection device can be ensured. Similarly, by setting the distance the trigger element needs to move to activate the unlocking position detection device to be less than the unlocking positioning section, more reliable activation of the unlocking position detection device can be ensured. These settings improve the accuracy of position detection, reduce the probability of false detection, and even eliminate false detection altogether.

[0031] Optionally, the rotating frame is rotatably connected to the cover about a first axis.

[0032] The two ends of the drive section are respectively connected to the lock cover positioning section and the unlocking positioning section.

[0033] The width of both the locking cover positioning section and the unlocking positioning section is greater than the width of the driving section.

[0034] According to this application, by setting the width of the lock cover positioning section and the unlocking positioning section to be greater than the width of the drive section, the guide connector can be moved more easily from the drive section to the lock cover positioning section and the unlocking positioning section, thereby reducing or avoiding the guide connector getting stuck at the connection between the drive section and the lock cover positioning section and the unlocking positioning section, respectively.

[0081] 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.

[0082] 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.

[0083] like Figures 1 to 12 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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).

[0091] 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.

[0092] 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 body 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 member 131. The fastening member 131 is movably connected to the lid body 110 in the locked and unlocked positions along the radial direction of the inner cover 113. The radial direction is a straight line intersecting and perpendicular to the first axis AX1. Correspondingly, the axial direction is a direction parallel to the first axis AX1. 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 clamp for accommodating the edge of the inner pot 101 and the edge of the inner lid 113. When the fastening member 131 is in the locked position, the edge of the inner pot 101 and the edge of the inner lid 113 are clamped in the clamp to limit the inner pot 101 and the inner lid 113 in the height direction D3 of the pressure cooking appliance, thereby preventing the inner pot 101 and the inner lid 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 clamp disengages from at least one of the edges of the inner pot 101 and the inner lid 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 fastener 131. The drive motor 134 is connected to a control unit to drive the fastener 131 to move between a locked position and an unlocked position under the control of the control unit.

[0093] 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 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 cover 110. 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 cover 110, thereby enabling the drive fastener 131 to move radially in the cover 110. The fastener 131 is movably connected to the guide hole 132a. The rotating frame 132 is driveably connected to a drive motor 134. As the drive motor 134 drives the rotating frame 132 to rotate, the fastener 131 slides relative to the rotating frame 132 along the extension trajectory of the guide hole 132a, thereby enabling the drive fastener 131 to move between a locked position and an unlocked position.

[0094] 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.

[0095] See Figure 11 and Figure 12Exemplarily, 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 137a and a screw. The stud 137a is connected to the top of the fastener 131. The stud 137a passes through the guide hole 112b and the guide hole 132a and is connected to the screw. The guide cavity 112a and the guide hole 112b may extend radially about a first axis AX1. The fastener 131 may include a first fastening portion 131b, a second fastening portion 131c, and a connecting portion 131d. A 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 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 clamp with an opening facing the first axis AX1. The clamp 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 up in the cooking space. The second fastening portion 131c is used to restrict the downward movement of the pot liner 101 when pressed up in the cooking space. In the radial direction of the inner lid 113, the first fastening portion 131b is longer than the second fastening portion 131c. Furthermore, the end of the first fastening portion 131b that is at least away 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 the movement towards the locked position. When the cover 110 is closed on 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 the movement towards the locked position.

[0096] See Figures 2 to 6 ,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 a rotation center portion 133a and a free end 133b. The rotation center portion 133a is rotatably connected to the cover 110 about a second axis AX2. The rotation center portion 133a is connected to the motor shaft 134a of the drive motor 134 to rotate synchronously with the motor shaft 134a. The free 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 motor shaft 134a has 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.

[0097] See Figure 3 , Figures 5 to 8 Optionally, the rotating frame 132 is provided with a trigger 132c. The position detection device 140 includes a locking position detection device 141 corresponding to the locked position and an unlocking position detection device 142 corresponding to the unlocked 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 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 132c in the circumferential direction around the first axis AX1. The trigger 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 5The 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 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 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.

[0098] See Figures 2 to 10 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 132c are arranged circumferentially around the first axis AX1.

[0099] 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.

[0100] See Figure 3 , Figures 5 to 8In addition, 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 is separated 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 the fourth limit position, the fastener 131 moves to the locked position, and the drive boss 132d engages with the lid latch 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 third extreme position, the fastening member 131 moves to the unlocked position, and the transmission boss 132d separates from the lid latch 160. It should be noted that the angle at which the rotating frame 132 rotates from the third extreme position to the fourth extreme position is less than or equal to the central angle corresponding to the circle centered on the first axis AX1 with the guide hole 132a. The central angle corresponding to the circle centered on the first axis AX1 with the transmission boss 132d can be less than or equal to the central angle corresponding to the guide hole 132a.

[0101] See 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.

[0102] Please refer to the following: Figures 1 to 12 The cooking appliance of the embodiments of this application is further described to illustrate that the embodiments of this application can keep the fastener 131 in the locked position and the unlocked position.

[0103] like Figures 2 to 8According to the cooking appliance of this application, a fastening member 131 is movably connected to the lid 110 between a locked position and an unlocked position. In the locked position, the fastening member 131 locks the lid 110 and the pot body 100. In the unlocked position, the fastening member 131 unlocks the lid 110 and the pot body 100. A rotating bracket 132 is movably connected to the lid 110. The rotating bracket 132 includes a guide hole 132a movably connected to the fastening member 131. The guide hole 132a includes a positioning section and a driving section 132a2. The positioning section is used to hold the fastening member 131 in the locked or unlocked position. The driving section 132a2 is used to drive the fastening member 131 to move between the locked and unlocked positions when the rotating bracket 132 moves. The width of the connection between the positioning section and the driving section 132a2 is greater than the width of the positioning section and / or the driving section 132a2.

[0104] During the rotation of the rotating frame 132, the fastening member 131 moves from the self-driving section 132a2 to the positioning section. When the fastening member 131 is in the positioning section, the fastening member 131 is held in the locked or unlocked position.

[0105] According to the cooking appliance of this application, during the movement of the rotating frame 132 relative to the lid 110, the fastening member 131 will move along the guide hole 132a relative to the rotating frame 132. When the fastening member 131 is located in the drive section 132a2, the fastening member 131 can move between the locked position and the unlocked position with the movement of the rotating frame 132. When the fastening member 131 is stationary in the positioning section, it can be held in the locked or unlocked position. By setting the positioning section, it is possible to prevent or avoid the fastening member 131 from moving from the locked or unlocked position to the drive section 132a2 due to the overall offset and sliding of the cooking appliance or the increase in internal pressure of the cooking space, which could cause the fastening member 131 to disengage or become stuck with the inner pot 101 and be unable to close the lid. This helps to keep the fastening member 131 in the locked or unlocked position, so as to reliably lock the pot body 100 and the lid 110 or smoothly close the lid, and improve the safety of cooking. During the process of the fastening member 131 moving from the driving section 132a2 to the positioning section or from the positioning section to the driving section 132a2, the width of the connection between the two is set to be greater than the width of the driving section 132a2 or the positioning section. This makes the fastening member 131 move more smoothly and avoids the fastening member 131 getting stuck at the junction of the two sections, which would prevent the fastening member 131 from moving accurately into place.

[0106] In this application, the guide connector 137 is fixedly connected to the fastener 131. The guide connector 137 slides in the guide hole 132a, thereby driving the movement of the fastener 131. During the process of the fastener moving along the drive section 132a2 to the positioning section or from the positioning section to the drive section 132a2, the width of the connection between the two is set to be greater than the width of the drive section 132a2 or the positioning section. This makes the movement of the fastener 131 smoother and avoids the fastener 131 getting stuck at the junction of the two sections, which would prevent the fastener 131 from moving accurately into place. Preferably, the connection between the positioning section and the drive section 132a2 is provided with a rounded corner to reduce the impact of the guide connector 137 on the rotating frame 132 during the transition between the drive section 132a2 and the positioning section.

[0107] like Figures 3 to 8 Optionally, the rotating frame 132 is rotatably connected to the cover 110 about a first axis AX1. The fastening member 131 moves in a radial direction perpendicular to the first axis AX1. The positioning section includes a cover positioning section 132a1. The driving section 132a2 has a locking end. The fastening member 131, when moved to the locking end, is in the locked position. The locking end is connected to the cover positioning section 132a1. The cover positioning section 132a1 extends in a circumferential direction centered on the first axis AX1. When the fastening member 131 is in the cover positioning section 132a1, the fastening member 131 is held in the locked position.

[0108] According to this application, by rotatably connecting the rotating frame 132 to the cover 110 and aligning the locking end of the drive section 132a2 with the locking position, the fastening member 131 can reach the locking position when it moves to the locking end of the drive section 132 as the rotating frame 132 rotates. Furthermore, by connecting the locking end to the cover positioning section 132a1, after the rotating frame 132 rotates further, the fastening member 131 moves to the cover positioning section 132a1. The cover positioning section 132a1 can restrict the fastening member 131 from moving radially towards the unlocking position under the influence of factors such as shaking, thereby maintaining the fastening member 131, which has moved to the locking position, in the locked position.

[0109] like Figures 3 to 8 In addition, the guide hole 132a may also include an unlocking positioning section 132a3. The unlocking positioning section 132a3 is used to hold the fastener 131 in the unlocked position.

[0110] According to this application, an unlocking positioning segment is provided to keep the fastener in the unlocked position.

[0111] like Figures 3 to 8Exemplarily, the rotating frame 132 is rotatably connected to the cover 110 about a first axis AX1. The fastening member 131 moves in a radial direction perpendicular to the first axis AX1. The drive section 132a2 has an unlocking end. When the fastening member 131 moves to the unlocking end, it is in the unlocked position, and the unlocking end is connected to the unlocking positioning section 132a3. The unlocking positioning section 132a3 extends in a circumferential direction centered on the first axis AX1. When the fastening member 131 is in the unlocking positioning section 132a3, the fastening member 131 is held in the unlocked position.

[0112] According to this application, by rotating the frame 132 and connecting it to the cover 110, and by aligning the unlocking end of the drive section 132a2 with the unlocking position, the fastener 131 can reach the unlocking position when it moves to the unlocking end of the drive section 132a2 as the frame 132 rotates. The fastener 131 is then connected to the lock cover positioning section 132a1 via the unlocking end, thus maintaining the fastener 131, which has moved to the unlocking position, in the unlocking position.

[0113] like Figures 3 to 8 Exemplarily, the rotating frame 132 is rotatably connected to the cover 110 about a first axis AX1. The fastening member 131 moves relative to the cover 110 in a radial direction perpendicular to the first axis AX1. The drive segment 132a2 has a locking end and an unlocking end. The fastening member 131, in the locked position, moves to the locking end. The fastening member 131, in the unlocked position, moves to the unlocking end. The locking end and the unlocking end are spaced apart in a circumferential direction centered on the first axis AX1. The radial dimension of the drive segment 132a2 is equal to the distance the fastening member 131 moves between the locked and unlocked positions. The distance between the locking end and the first axis AX1 is less than the distance between the unlocking end and the first axis AX1.

[0114] According to this application, since the radial dimension of the drive section 132a2 is equal to the distance the fastener 131 moves between the locked position and the unlocked position, during the rotation of the rotating frame 132, the fastener 131 can move to the locked position when it moves along the guide hole 132a to the locking end, and the fastener 131 can move to the unlocked position when it moves along the guide hole 132a to the unlocked end.

[0115] Optionally, the extension trajectory of the drive segment 132a2 is inclined to the line connecting any point of the drive segment 132a2 and the first axis AX1. Here, the extension trajectory of the drive segment 132a2 can be a straight line, a curve, or a combination of both.

[0116] In examples not shown, the extension trajectory of at least one of the locking cover positioning section 132a1 and the unlocking positioning section 132a3, or the extension trajectory of the locking cover positioning section 132a1 and the driving section 132a2, or the extension trajectory of the unlocking positioning section 132a3 and the driving section 132a2, can also be U-shaped, J-shaped, or other irregular shapes, as long as they can provide a limiting effect on the position of the fastening member 131 in the radial direction perpendicular to the first axis AX1.

[0117] According to this application, the extension trajectory of the drive segment 132a2 is inclined to the line connecting any point of the drive segment 132a2 and the first axis AX1, which simplifies the structure of the drive segment and facilitates design and manufacturing.

[0118] like Figures 3 to 8 For example, the drive segment 132a2 extends in an extension direction inclined to the radial direction of the cover 110. The end of the drive segment 132a2 near the locking cover positioning segment 132a1 has a first distance from the first axis AX1. The end of the drive segment 132a2 near the unlocking positioning segment 132a3 has a second distance from the first axis AX1. The second distance is greater than the first distance. The extension trajectory of the locking cover positioning segment 132a1 intersects the extension trajectory of the drive segment 132a2. For example, the extension direction of the locking cover positioning segment 132a1 intersects the extension direction of the drive segment 132a2. In some examples, the extension direction of the locking cover positioning segment 132a1 is perpendicular to the radial direction of the circle with respect to the first axis AX1. The position of the locking cover positioning segment 132a1 relative to the first axis AX1 remains unchanged. The extension trajectory of the unlocking positioning segment 132a3 intersects the extension trajectory of the drive segment 132a2. For example, the extension direction of the unlocking positioning segment 132a3 intersects the extension direction of the drive segment 132a2. The extension direction of the unlocking positioning section 132a3 is inclined to or perpendicular to the radial direction of the circle with the first axis AX1. Similar to the locking cover positioning section 132a1, if the extension direction of the unlocking positioning section 132a3 is perpendicular to the radial direction of the circle with the first axis AX1, then the unlocking positioning section 132a3 is adapted to keep the position of the fastener 131 unchanged during the rotation of the rotating frame 132.

[0119] See Figure 8 and Figure 9For example, drive segment 132a2 has a first center point Pt1 and a second center point Pt2 spaced along its extended trajectory. The first center point Pt1 is located at the locking end of drive segment 132a2. The second center point Pt2 is located at the unlocking end of drive segment 132a2. The distance between the first center point Pt1 and the first axis AX1 is less than the distance between the second center point Pt2 and the first axis AX1. The extended trajectory of drive segment 132a2 has arbitrarily adjacent first arbitrary position points (not shown) and second arbitrary position points (not shown) arranged sequentially in a circumferential direction centered on the first axis AX1. The first arbitrary position point is closer to the first center point Pt1 than the second arbitrary position point. The distance between the first arbitrary position point and the first axis AX1 is less than or equal to the distance between the second arbitrary position point and the first axis AX1. In other words, in the direction moving from the first center point Pt1 towards the second center point Pt2, the distance between drive segment 132a2 and the first axis AX1 increases. When the fastening member 131 moves relative to the rotating frame 132 towards the first center point Pt1 via the guide connector in the drive section 132a2, the fastening member 131 can move towards the locked position. When the fastening member 131 moves relative to the rotating frame 132 towards the second center point Pt2 via the guide connector in the drive section 132a2, the fastening member 131 can move towards the unlocked position.

[0120] The first center point Pt1 is closer to the locking cover positioning section 132a1 than the second center point Pt2. The locking cover positioning section 132a1 has a third center point Pt3 and a first center point Pt1 spaced apart along its extension trajectory. That is, the extension trajectory of the locking cover positioning section 132a1 coincides with the extension trajectory of the drive section 132a2 at the first center point Pt1. The distance between the third center point Pt3 and the first axis AX1 is equal to the distance between the first center point Pt1 and the first axis AX1. The extension trajectory of the locking cover positioning section 132a1 is an arc centered on the first axis AX1 with a radius equal to the distance between the first center point Pt1 and the first axis AX1, thereby enabling the locking cover positioning section 132a1 to hold the fastener 131 in the locked position.

[0121] The first center point Pt1 is farther away from the unlocking positioning segment 132a3 than the second center point Pt2. The unlocking positioning segment 132a3 has an extension trajectory along which the second center point Pt2 and the fourth center point Pt4 are spaced apart. The extension trajectory of the unlocking positioning segment 132a3 coincides with the extension trajectory of the driving segment 132a2 at the second center point Pt2. The distance between the second center point Pt2 and the first axis AX1 is equal to the distance between the fourth center point Pt4 and the first axis AX1. The extension trajectory of the unlocking positioning segment 132a3 is an arc centered on the first axis AX1 with a radius equal to the distance between the second center point Pt2 and the first axis AX1, thereby enabling the unlocking positioning segment 132a3 to hold the fastener 131 in the unlocked position.

[0122] like Figures 3 to 8 For example, the rotating rack 132 includes a trigger 132c. The cooking appliance also includes a position detection device 140. When the fastener 131 moves to the locked position and / or unlocked position, the trigger 132c triggers the position detection device 140.

[0123] According to this application, by providing a trigger 132c on the rotating frame and a position detection device 140, a position signal can be detected when the fastener 131 moves to the locked position and / or the unlocked position, thereby determining that the fastener 131 has moved into place.

[0124] like Figures 3 to 8 Exemplarily, the rotating frame 132 is rotatably connected to the cover 110 about a first axis AX1. The trigger 132c is configured as a protrusion extending outward from the edge of the rotating frame 132 in a radial direction along the first axis AX1. The position detection device 140 includes a locked position detection device 141 and an unlocked position detection device 142. The locked position detection device 141 and the unlocked position detection device 142 are located at opposite ends of the travel of the trigger 132c as it rotates with the rotating frame 132. One end of the travel of the trigger 132c as it rotates with the rotating frame 132 corresponds to the locked position detection device 141. The other end of the travel of the trigger 132c as it rotates with the rotating frame 132 corresponds to the locked position detection device 141.

[0125] According to this application, by setting the trigger 132c as a protrusion extending outward in the radial direction from the edge of the rotating frame 132, and arranging the locking position detection device 141 and the unlocking position detection device 142 at both ends of the rotation stroke of the trigger 132c, it is possible to reduce the space occupied on the upper and / or lower side of the rotating frame 132 while achieving the purpose of position detection, and it also helps to reduce the thickness of the cover 110.

[0126] like Figures 3 to 8 Exemplarily, the guide hole 132a also includes an unlocking positioning section 132a2. The unlocking positioning section 132a2 is used to hold the fastener 131 in the unlocked position. The position detection device 140 includes a locked position detection device 141 and an unlocked position detection device 142. Each of the locked position detection device 141 and the unlocked position detection device 142 is a microswitch. The movement distance of the trigger member 132c from abutting the locked position detection device 141 to triggering the locked position detection device 141 is less than the length of the locking cover positioning section. The movement distance of the trigger member 132c from abutting the unlocked position detection device 142 to triggering the unlocked position detection device 142 is less than the length of the unlocking positioning section.

[0127] According to this application, when a micro switch is selected as the position detection device 140, the trigger 132c can trigger the position detection device 140 by abutting against it during the rotation of the rotating frame 132. However, the trigger 132c typically needs to move a certain distance from the moment it abuts against the micro switch. By setting the distance the trigger 132c needs to move to trigger the locking position detection device 141 to be less than the locking cover positioning section 132a1, more reliable triggering of the locking position detection device 141 can be ensured. Similarly, by setting the distance the trigger 132c needs to move to trigger the unlocking position detection device 142 to be less than the unlocking positioning section 132a3, more reliable triggering of the unlocking position detection device 142 can be ensured. These settings improve the accuracy of position detection, reduce the probability of false detection, and even prevent false detection altogether.

[0128] like Figures 3 to 8 For example, the rotating frame 132 is rotatably connected to the cover 110 about the first axis AX1. The two ends of the drive section 132a2 are respectively connected to the locking cover positioning section 132a1 and the unlocking positioning section 132a3. In the radial direction centered on the first axis AX1, the width of both the locking cover positioning section 132a1 and the unlocking positioning section 132a3 is greater than the width of the drive section 132a2.

[0129] According to this application, by setting the widths of the lock cover positioning section 132a1 and the unlocking positioning section 132a3 to be greater than the width of the drive section 132a2, the guide connector 137 can be more easily moved from the drive section 132a2 into the lock cover positioning section 132a1 and the unlocking positioning section 132a3. This reduces or avoids the guide connector 137 getting stuck at the connection point between the drive section 132a2 and either the lock cover positioning section 132a1 or the unlocking positioning section 132a3. Furthermore, the width of the connection point can be the same as the width of the lock cover positioning section 132a1 and the unlocking positioning section 132a3, making molding easier. The diameter of the guide connector 137 is smaller than the width of the drive section 132a2, and the difference should not be too large, so that the guide connector 137 can be more easily driven radially by the drive section 132a2.

[0130] Furthermore, the diameter of the guide connector 137 is smaller than the length of the positioning section, which makes it more likely that the guide connector 137 will move into the positioning section when the fastener 131 is in the locked or unlocked position, rather than getting stuck at the connection between the positioning section and the drive section 132a2. This makes it easier for the subsequent rotating frame 132 to move the guide connector 137 into the drive section 132a2.

[0131] Optionally, the length of the extension trajectory of either the locking cover positioning section 132a1 or the opening cover positioning section 132a3 is greater than the diameter of the guide connector 137.

[0132] Exemplarily, the rotating frame 132 has four guide holes 132a evenly arranged around its circumference. The portion of the cover 112 corresponding to the guide holes 132a has a guide cavity 112a. The width of the fastening member 131 is smaller than the width of the guide cavity 112a, and the fastening member 131 can slide along the groove direction of the guide cavity 112a. A stud 137a is welded to the back of the fastening member 131. A sliding limit block (not shown) is also included. The sliding limit block has a hole with a diameter larger than the diameter of the stud 137a. The outer diameter of the sliding limit block is smaller than the width of the guide hole 112b on the guide cavity 112a. The width of the guide hole 112b is its dimension in the direction perpendicular to the first axis AX1 and in the radial direction. The bottom of the sliding limit block is circular. A compression spring is mounted on the stud 137a. The sliding limit block is mounted above the compression spring. A cover 112, a rotating bracket 132, and finally a screw are installed sequentially on top of the sliding limit block. At this point, the lower surface of the sliding limit block is at a certain distance from the upper surface of the fastener 131. The spring force of the compression spring holds the sliding limit block in the guide hole 112b of the cover 112, preventing the stud 137a from directly contacting the guide hole 112b. This reduces the friction between the stud 137a and the guide hole 112b.
