[0001] The utility model relates to the technical field of cooking utensils, in particular to a cover assembly and a cooking utensil. Background Art

[0002] At present, in the related technology, a cover assembly is provided in the cooking appliance, and the cover assembly is connected to the shell of the cooking appliance through a hinge. The cover assembly is provided with a motor for driving the cover assembly to rotate. Since the motor is arranged on a side of the cover assembly close to the hinge, in order to make the motor avoid the hinge structure, it is necessary to reserve a position for setting the motor on the side of the cover assembly close to the hinge, which increases the volume of the cover assembly. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the utility model provides a cover assembly.

[0005] A second aspect of the present invention provides a cooking utensil.

[0006] In view of this, the first aspect of the utility model provides a cover assembly, which is used for a cooking utensil, the cooking utensil includes a pot body, the cover assembly can be covered on the pot body, and the cover assembly includes a cover body, a locking component, a transmission component and a drive component. The locking component is connected to the cover body, can rotate relative to the cover body, and can cooperate with the pot body, the transmission component is connected to the locking component, and the drive component is connected to the transmission component to drive the locking component to move through the transmission component. A first area is provided between the transmission component and two adjacent edges of the cover body, and the drive component is located in the first area.

[0007] The present application provides a cover assembly, which is used for a cooking utensil. The cooking utensil includes a pot body, and the cover assembly can be covered on the pot body. The cover assembly includes a cover body, a locking component, a transmission component and a drive component. The cover body in the cover assembly can be buckled on the pot body, and the cover body and the pot body form a cooking space. The cover assembly is also provided with a locking component, which is connected to the cover body, can rotate relative to the cover body, and can cooperate with the pot body to seal the pot body. When the cooking utensil is working, the internal gas is heated, and the air pressure of the internal environment increases accordingly. The locking component cooperates with the pot body to improve the airtightness of the pot body, so that there is a certain pressure in the pot body, which can improve the cooking effect of the cooking utensil on food. At the same time, the locking of the pot body by the locking component can improve the safety of the cooking utensil when it is working. At the same time, the locking component is connected to the cover body and can rotate relative to the cover body, which is convenient for opening and closing the cooking utensil. The transmission assembly in the cover assembly is connected to the locking component, and the driving assembly is connected to the transmission assembly, so that the locking component is driven to move by the transmission assembly, thereby realizing the control of the opening and closing state of the locking component by the driving assembly. Since a first area is provided between the transmission assembly and two adjacent edges of the cover body, placing the driving assembly in the first area can reduce the width reserved between the sliding track of the transmission assembly and the edge of the cover body for placing the driving assembly, thereby reducing the volume of the cover assembly, and reducing the production cost of the cooking utensil. At the same time, placing the driving assembly in the first area can keep the driving assembly away from the high-temperature area in the center of the cover body, thereby reducing the high-temperature resistance requirements for the material of the driving assembly, and reducing the production cost of the driving assembly. Since the internal pressure of the cooking utensil increases when it is working, the cover body will be slightly deformed under pressure. Setting the drive component at a position close to the edge of the cover body at the edge of the transmission component can reduce the impact of the pot pressure of the cooking utensil on the contact area between the drive component and the transmission component, thereby improving the transmission stability of the drive component and the transmission component. At the same time, the drive component is set in the first area close to the edge of the transmission component, the torque of the transmission component becomes larger, and the driving force of the drive component required for the transmission component to achieve the same transmission effect is reduced, thereby reducing the power of the drive component, reducing the requirements for the power parameters of the drive component, and reducing the production cost of the drive component.

[0008] Furthermore, by arranging the driving assembly in the first area, the size of the driving assembly can be increased under the volume of the original cover assembly, the power of the driving assembly can be improved, and the driving effect of the driving assembly on the transmission assembly and the locking component can be optimized.

[0009] In addition, the cover assembly in the above technical solution provided by the utility model may also have the following additional technical features:

[0010] In some technical solutions of the present invention, optionally, the transmission assembly includes a rack having a first slide groove, the cover body includes a first mounting column, the first mounting column is located in the first slide groove and can slide relative to the first slide groove, the driving assembly includes a driving component and a gear, the output shaft of the driving component is connected to the gear, and the gear is meshed with the rack.

[0011] In this technical solution, the transmission assembly includes a rack, a first slide groove is arranged on the rack, the cover body includes a first mounting column, the first mounting column is located in the first slide groove and can slide relative to the first slide groove, the driving assembly includes a driving component and a gear, the output shaft of the driving component is connected to the gear, the gear is meshed with the rack, the rotation of the gear can drive the rack to move, and then the transmission assembly moves along with the rotation of the gear, since the first mounting column arranged on the cover body is located in the first slide groove, and the first slide groove is arranged on the rack, when the rack moves, the movement trajectory of the rack can be limited by the first mounting column, and the locking state of the locking component can be controlled by the movement of the rack, thereby simplifying the structure of the transmission assembly and the driving assembly, and facilitating the driving assembly to control the opening and closing state of the locking component through the transmission assembly.

[0012] In some technical solutions of the present utility model, optionally, the cover assembly further comprises a cover plate, which is connected to the cover body and is located on a side of the locking component away from the cover body, and the driving component is offset relative to the cover plate.

[0013] In this technical solution, the cover assembly also includes a cover plate, which is connected to the cover body and is located on the side of the locking component away from the cover body. The driving component is offset relative to the cover plate. Since the cooking appliance is in a heating state when working and the cover plate is located on the side of the locking component away from the cover body, the temperature of the cover plate increases. Offsetting the driving component relative to the cover plate can reduce the heat received by the driving component, protect the driving component, extend the service life of the driving component, and reduce the use cost of the cooking appliance.

[0014] Furthermore, the drive component can be subjected to high temperature resistance treatment by changing the material of the drive component.

[0015] Specifically, the driving component may be a motor.

[0016] In some technical schemes of the utility model, optionally, on the cross section of the cover assembly, the intersection of the axis of the driving component and the cross section is the first point, the intersection of the rotation axis of the locking component and the cross section is the second point, and the line connecting the first point and the second point is the first connecting line, wherein the cross section is perpendicular to the axial direction of the driving component; there is a second connecting line on the cross section, the second connecting line passes through the second point, and is perpendicular to the edge of the cover body on the side close to the driving component, and the angle between the first connecting line and the second connecting line is greater than or equal to 20 degrees and less than or equal to 70 degrees.

[0017] In this technical solution, on the cross section of the cover assembly, the intersection of the axis of the driving component and the cross section is the first point, the intersection of the rotation axis of the locking component and the cross section is the second point, and the line connecting the first point and the second point is the first connecting line, wherein the cross section is perpendicular to the axial direction of the driving component; there is a second connecting line on the cross section, the second connecting line passes through the second point, and is perpendicular to the edge of the cover body on the side close to the driving component, and the angle between the first connecting line and the second connecting line is greater than or equal to 20 degrees and less than or equal to 70 degrees. The position of the driving component can be set in the angle space between the first edge and the second edge, the second edge and the third edge, the third edge and the fourth edge, or the first edge and the fourth edge of the cover body, thereby reducing the space reserved for the driving component, reducing the volume of the cover assembly, and reducing the production and installation cost of the cover assembly. At the same time, the driving assembly in the cover assembly is set in the first area away from high temperature, which can reduce the high temperature resistance requirements for the material of the driving assembly during the production process and reduce the production cost of the driving assembly.

[0018] Specifically, the first point is P1, the second point is P2, the first direction is T, the first connecting line is L, the first center line is H, and the angle between the first connecting line L and the first center line H is α, where the range of angle α is: angle α is greater than or equal to 20 degrees and less than or equal to 70 degrees.

[0019] Specifically, the angle α=20 degrees, the angle α=40 degrees, the angle α=60 degrees, and the angle α=70 degrees.

[0020] In some technical solutions of the present utility model, optionally, the distance between the axis of the driving component and the center of the cover plate is a first distance, and the first distance is greater than the radius of the cover plate.

[0021] In this technical solution, the distance between the axis of the driving component and the center of the cover is a first distance, and the first distance is greater than the radius of the cover. Since the temperature inside the pot body under the cover increases during cooking, arranging the driving component away from the center of the cover can reduce the temperature to which the driving component is subjected when the cooking appliance is working, thereby extending the service life of the driving component.

[0022] Specifically, the first distance is D, the radius of the cover plate is R, and D is greater than R.

[0023] In some technical solutions of the present invention, optionally, the locking component includes a second mounting column, the second mounting column passes through the cover body, a first end of the second mounting column is connected to the rack, and a second end is connected to the locking component.

[0024] In this technical solution, the locking component includes a second mounting column, the second mounting column is passed through the cover body, the first end of the second mounting column is connected to the rack, and the second end is connected to the locking component. By setting the second mounting column, the rack drives the second mounting column to realize the driving of the locking component, and then the locking state and unlocking state of the locking component can be controlled, which is convenient for driving the locking component, reducing the volume of the transmission component, and reducing the volume of the cover component. Under the same volume of the cover component, a driving component with higher horsepower can be installed to facilitate the opening and closing of the locking component, or the volume of the exhaust component can be increased accordingly, thereby increasing the exhaust efficiency of the cooking appliance and improving the use effect of the cooking appliance.

[0026] In this technical solution, the rack is provided with a mounting hole, the second mounting post is passed through the mounting hole, and the rack drives the second mounting post through the mounting hole, thereby realizing the driving of the locking component.

[0027] Furthermore, a mounting hole is directly opened on the rack, which facilitates the production and installation of the transmission assembly and reduces the installation cost of the cover assembly.

[0028] In some technical solutions of the present utility model, optionally, in the radial direction of the locking component, there is a gap between the second mounting column and the inner wall of the mounting hole.

[0029] In this technical solution, in the radial direction of the locking component, there is a gap between the second mounting column and the inner wall of the mounting hole. When the transmission component is working, the mounting hole on the rack drives the second mounting column. Since there is a gap between the second mounting column and the mounting hole, the sliding distance of the rack can be reserved, so that the rack slides in parallel without contacting the second mounting column. The gap in the non-rack sliding direction can reduce the friction between the second mounting column and the mounting hole, extend the service life of the second mounting column and the mounting hole, reduce resistance, and facilitate the driving of the locking component by the driving component and the transmission component. The gap in the rack sliding direction can realize that the rack controls the valve body to open the exhaust component before controlling the locking component to open the unlocking state, enriching the control mode of the transmission component, realizing exhaust treatment of the cooking utensil before unlocking the locking component, and facilitating the opening of the cooking utensil.

[0031] In this technical solution, the transmission assembly has a first position and a second position. When the transmission assembly is in the first position, the driving component drives the rack through the gear, the rack moves, and then the transmission assembly slides parallel to the first mounting column, and the transmission component drives the second mounting column on the locking component through the mounting hole, and the locking component is locked with the pot body. When the transmission assembly is in the second position, the driving component drives the rack through the gear, the rack moves, and then the transmission assembly slides parallel to the opposite direction relative to the first mounting column, and the transmission component drives the second mounting column on the locking component through the mounting hole, and the locking component is unlocked with the pot body, thereby simplifying the structure of the driving component and the transmission component, reducing the volume of the cover assembly, and reducing the production and installation cost of the cover assembly.

DETAILED DESCRIPTION

[0048] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0050] Refer to the following Figures 1 to 4 A lid assembly 100 and a cooking appliance 200 according to some embodiments of the present invention are described.

[0051] In an embodiment of the present utility model, a cover assembly 100 is provided, such as Figure 1 and Figure 2 As shown, the cover assembly 100 is used for a cooking utensil 200, which includes a pot body 210. The cover assembly 100 can be covered on the pot body 210. The cover assembly 100 includes a cover body 110, a locking component 120, a transmission component 150, and a driving component 160. The locking component 120 is connected to the cover body 110, can rotate relative to the cover body 110, and can cooperate with the pot body 210. The transmission component 150 is connected to the locking component 120, and the driving component 160 is connected to the transmission component 150 to drive the locking component 120 to move through the transmission component 150. Among them, a first area 116 is provided between the transmission component 150 and two adjacent edges 114 of the cover body 110, and the driving component 160 is located in the first area 116.

[0052] The present application provides a cover assembly 100, which is used for a cooking utensil 200, and the cooking utensil 200 includes a pot body 210. The cover assembly 100 can be covered on the pot body 210, and the cover assembly 100 includes a cover body 110, a locking component 120, a transmission assembly 150, and a driving assembly 160. The cover body 110 in the cover assembly 100 can be buckled on the pot body 210, and the cover body 110 and the pot body 210 form a cooking space. A locking component 120 is also provided in the cover assembly 100. The locking component 120 is connected to the cover body 110 and can rotate relative to the cover body 110, and can cooperate with the pot body 210 to seal the pot body 210. When the cooking utensil 200 is working, the internal gas is heated and the air pressure of the internal environment increases accordingly. The locking component 120 and the pot body 210 cooperate to improve the airtightness of the pot body 210, so that there is a certain pressure in the pot body 210, which can improve the cooking effect of the cooking utensil 200 on food. At the same time, the locking of the pot body 210 by the locking component 120 can improve the safety of the cooking utensil 200 when it is working. At the same time, the locking component 120 is connected to the cover body 110 and can rotate relative to the cover body 110, which is convenient for opening and closing the cooking utensil 200. The transmission assembly 150 in the cover assembly 100 is connected to the locking member 120, and the driving assembly 160 is connected to the transmission assembly 150, so that the locking member 120 is driven to move by the transmission assembly 150, thereby realizing the control of the opening and closing state of the locking member 120 by the driving assembly 160. Since the first area 116 is provided between the transmission assembly 150 and two adjacent edges 114 of the cover body 110, placing the driving assembly 160 in the first area 116 can reduce the width reserved between the sliding track of the transmission assembly 150 and the edge 114 of the cover body 110 for placing the driving assembly 160, thereby reducing the volume of the cover assembly 100, and reducing the production cost of the cooking utensil 200. At the same time, placing the driving assembly 160 in the first area 116 can keep the driving assembly 160 away from the high temperature area in the center of the cover body 110, thereby reducing the high temperature resistance requirements of the material of the driving assembly 160, and reducing the production cost of the driving assembly 160. Since the internal pressure of the cooking utensil 200 increases when it is working, the cover body 110 will be slightly deformed under pressure. By setting the driving component 160 at the position of the transmission component 150 close to the edge 114 of the cover body 110, the contact area between the driving component 160 and the transmission component 150 can be reduced from being affected by the pressure of the pot body 210 of the cooking utensil 200, thereby improving the transmission stability of the driving component 160 and the transmission component 150. At the same time, the driving component 160 is set in the first area 116 close to the transmission component 150, the torque of the transmission component 150 becomes larger, and the driving force of the driving component 160 required for the transmission component 150 to achieve the same transmission effect is reduced, thereby reducing the power of the driving component 160, reducing the requirements for the power parameters of the driving component 160, and reducing the production cost of the driving component 160.

[0053] Furthermore, by disposing the driving assembly 160 in the first area 116 , the size of the driving assembly 160 can be increased within the volume of the original cover assembly 100 , thereby improving the power of the driving assembly 160 and optimizing the driving effect of the driving assembly 160 on the transmission assembly 150 and the locking component 120 .

[0054] Specifically, Figure 2 As shown, the cover body 110 is rectangular, and the cover body 110 may also be polygonal, such as a pentagon or a hexagon. The rectangular cover body 110 is sequentially provided with a first edge 1142, a second edge 1144, a third edge 1146 and a fourth edge 1148, wherein the first edge 1142 and the second edge 1144 are two adjacent edges 114, the second edge 1144 and the third edge 1146 may be two adjacent edges 114, the third edge 1146 and the fourth edge 1148 may be two adjacent edges 114, and at the same time, the first edge 1142 and the fourth edge 1148 may be two adjacent edges 114.

[0055] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0056] Specifically, the outer edge of the transmission assembly 150 can be as close to the edge of the cover body 110 as possible, so that the transmission ratio of the transmission assembly 150 is larger, so that when the transmission assembly 150 drives the locking component 120, the output torque of the driving component 162 is reduced.

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, the transmission assembly 150 includes a rack 152, and a first slide groove 1522 is arranged on the rack 152. The cover body 110 includes a first mounting column 112, and the first mounting column 112 is located in the first slide groove 1522 and can slide relative to the first slide groove 1522. The driving assembly 160 includes a driving component 162 and a gear 164. The output shaft 1622 of the driving component 162 is connected to the gear 164, and the gear 164 is meshed with the rack 152.

[0058] In this embodiment, the transmission assembly 150 includes a rack 152, and the rack 152 is provided with a first slide groove 1522. The cover body 110 includes a first mounting column 112, and the first mounting column 112 is located in the first slide groove 1522 and can slide relative to the first slide groove 1522. The driving assembly 160 includes a driving component 162 and a gear 164. The output shaft 1622 of the driving component 162 is connected to the gear 164, and the gear 164 is meshed with the rack 152. The rotation of the gear 164 can drive the rack 152 to move, and then the transmission assembly 150 is accompanied by the gear 1 64 is moved by rotating. Since the first mounting column 112 arranged on the cover body 110 is located in the first slide groove 1522, and the first slide groove 1522 is arranged on the rack 152, when the rack 152 moves, the movement trajectory of the rack 152 can be limited by the first mounting column 112, and the locking state of the locking component 120 can be controlled by the movement of the rack 152, which simplifies the structure of the transmission component 150 and the driving component 160, and facilitates the driving component 160 to control the opening and closing state of the locking component 120 through the transmission component 150.

[0059] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0060] like Figure 1 , Figure 2 and Figure 3 As shown, the cover assembly 100 further includes a cover plate 130 , which is connected to the cover body 110 and is located on a side of the locking component 120 away from the cover body 110 . The driving component 162 is offset relative to the cover plate 130 .

[0061] In this embodiment, the cover assembly 100 also includes a cover plate 130, which is connected to the cover body 110 and is located on the side of the locking component 120 away from the cover body 110. The driving component 162 is offset relative to the cover plate 130. Since the cooking appliance 200 is in a heating state when working, and the cover plate 130 is located on the side of the locking component 120 away from the cover body 110, the temperature of the cover plate 130 increases. Offsetting the driving component 162 relative to the cover plate 130 can reduce the heat received by the driving component 162, protect the driving component 162, extend the service life of the driving component 162, and reduce the use cost of the cooking appliance 200.

[0062] Furthermore, the driving component 160 may be subjected to high temperature resistance treatment by changing the material of the driving component 160 .

[0064] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0065] like Figure 1 , Figure 2 and Figure 3 As shown, on the cross section 190 of the cover assembly 100, the intersection of the axis of the driving component 162 and the cross section 190 is the first point, the intersection of the rotation axis of the locking component 120 and the cross section 190 is the second point, and the line connecting the first point and the second point is the first connecting line, wherein the cross section 190 is perpendicular to the axial direction of the driving component 162; there is a second connecting line on the cross section 190, the second connecting line passes through the second point, and is perpendicular to the edge of the cover body 110 on the side close to the driving component 162, and the angle between the first connecting line and the second connecting line is greater than or equal to 20 degrees and less than or equal to 70 degrees.

[0066] In this embodiment, on the cross section 190 of the cover assembly 100, the intersection of the axis of the driving component 162 and the cross section 190 is the first point, the intersection of the rotation axis of the locking component 120 and the cross section 190 is the second point, and the line connecting the first point and the second point is the first connecting line, wherein the cross section 190 is perpendicular to the axial direction of the driving component 162; there is a second connecting line on the cross section 190, the second connecting line passes through the second point, and is perpendicular to the edge of the cover body 110 on the side close to the driving component 162, and the angle between the first connecting line and the second connecting line is greater than or equal to 20 degrees and less than or equal to 70 degrees, so that the position of the driving component 162 can be adjusted. The drive component 162 is arranged at the angle space between the first edge 1142 and the second edge 1144, the second edge 1144 and the third edge 1146, the third edge 1146 and the fourth edge 1148, or the first edge 1142 and the fourth edge 1148 of the cover body 110, thereby reducing the space reserved for the drive component 162, reducing the volume of the cover assembly 100, and reducing the production and installation cost of the cover assembly 100. At the same time, the drive assembly 160 in the cover assembly 100 is arranged in the first area 116 away from high temperature, which can reduce the high temperature resistance requirements of the material of the drive assembly 160 during the production process and reduce the production cost of the drive assembly 160.

[0067] Specifically, Figure 3 As shown, the axis of the driving component 162 is X. Figure 3 and Figure 4 As shown, the rotation axis of the locking component 120 is Z.

[0068] Specifically, the intersection point of the axis X of the driving component 162 and the cross section 190 is the first point, namely, point P1. The intersection point of the rotation axis Z of the locking component 120 and the cross section 190 is the second point, namely, point P2.

[0069] Specifically, the radial direction of the driving component 162 is direction J.

[0070] Specifically, Figure 1 and Figure 2 As shown, the axial direction of the driving component 162 is direction N.

[0071] Further, when the cover 110 is a regular shape, that is, the cross section 190 of the cover 110 is rectangular, square, hexagonal, circular, elliptical, etc., the second connection line can be the center line of the cover 110. The cover 110 can be provided with two center lines, namely a first center line H and a second center line M, wherein the first center line H and the second center line M are perpendicular to each other, and then the first edge 1142, the second edge 1144, the first center line H, the second center line M and the transmission assembly 150 can enclose the first area 116, and the driving assembly 160 can be provided in the first area 116.

[0072] Further, when the cover 110 is an irregular shape, the second connecting line is the center line of the axial section of the pot body 210. Specifically, the first direction is T, the first connecting line is L, the second connecting line includes the first center line, that is, the first center line H, and the angle between the first connecting line L and the first center line H is α, wherein the range of the angle α is: the angle α is greater than or equal to 20 degrees and less than or equal to 70 degrees.

[0073] Specifically, the angle α=20 degrees, the angle α=40 degrees, the angle α=60 degrees, and the angle α=70 degrees.

[0074] At the same time, the third edge 1146 , the second edge 1144 , the first center line H, the second center line M and the transmission component 150 can enclose a first area 116 , and the driving component 160 can be disposed in the first area 116 .

[0075] At the same time, the third edge 1146 , the fourth edge 1148 , the first center line H, the second center line M and the transmission component 150 can enclose a first area 116 , and the driving component 160 can be disposed in the first area 116 .

[0076] At the same time, the first edge 1142 , the fourth edge 1148 , the first center line H, the second center line M and the transmission component 150 can enclose a first area 116 , and the driving component 160 can be disposed in the first area 116 .

[0077] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0078] like Figure 1 , Figure 2 and Figure 3 As shown, the distance between the axis of the driving component 162 and the center of the cover plate 130 is a first distance, and the first distance is greater than the radius of the cover plate 130 .

[0079] In this embodiment, the distance between the axis of the driving component 162 and the center of the cover 130 is a first distance, and the first distance is greater than the radius of the cover 130. Since the temperature inside the pot body 210 below the cover 130 increases during cooking, arranging the driving component 162 away from the center of the cover 130 can reduce the temperature to which the driving component 162 is subjected when the cooking utensil 200 is working, thereby extending the service life of the driving component 162.

[0080] Specifically, the first distance is D, the radius of the cover plate 130 is R, and D is greater than R.

[0081] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0082] like Figure 1 , Figure 2 and Figure 3 As shown, the locking component 120 includes a second mounting column 122 , which passes through the cover body 110 , wherein a first end of the second mounting column 122 is connected to the rack 152 , and a second end of the second mounting column 122 is connected to the locking component 120 .

[0083] In this embodiment, the locking component 120 includes a second mounting column 122, and the second mounting column 122 is penetrated through the cover body 110. The first end of the second mounting column 122 is connected to the rack 152, and the second end is connected to the locking component 120. By setting the second mounting column 122, the rack 152 drives the second mounting column 122, so as to realize the driving of the locking component 120, and then the locking state and unlocking state of the locking component 120 can be controlled, which is convenient for driving the locking component 120, reducing the volume of the transmission assembly 150, and reducing the volume of the cover assembly 100. Under the same volume of the cover assembly 100, a driving component 162 with greater horsepower can be installed to facilitate the opening and closing of the locking component 120, or the volume of the exhaust component can be correspondingly increased to increase the exhaust efficiency of the cooking appliance 200 and improve the use effect of the cooking appliance 200.

[0084] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0085] like Figure 1 , Figure 2 and Figure 3 As shown, a mounting hole 1524 is provided on the rack 152 , and the second mounting post 122 passes through the mounting hole 1524 .

[0086] In this embodiment, the rack 152 is provided with a mounting hole 1524 , and the second mounting post 122 is passed through the mounting hole 1524 . The rack 152 drives the second mounting post 122 through the mounting hole 1524 , thereby driving the locking component 120 .

[0087] Furthermore, a mounting hole 1524 is directly opened on the rack 152 to facilitate the production and installation of the transmission assembly 150 and reduce the installation cost of the cover assembly 100 .

[0088] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0089] like Figure 1 , Figure 2 and Figure 3 As shown, in the radial direction of the locking component 120 , there is a gap between the second mounting column 122 and the inner wall of the mounting hole 1524 .

[0090] In this embodiment, in the radial direction of the locking component 120, there is a gap between the second mounting column 122 and the inner wall of the mounting hole 1524. When the transmission assembly 150 is working, the mounting hole 1524 on the rack 152 drives the second mounting column 122. Since there is a gap between the second mounting column 122 and the mounting hole 1524, a sliding distance for the rack 152 can be reserved, so that the rack 152 can slide in parallel without contacting the second mounting column 122. The gap in the non-sliding direction of the rack 152 can reduce the friction between the second mounting column 122 and the mounting hole 1524, thereby extending the service life of the second mounting column 122 and the mounting hole 1524, reducing resistance, and facilitating the driving of the locking component 120 by the driving component 162 and the transmission assembly 150.

[0091] Furthermore, the gap in the sliding direction of the rack 152 can enable the rack 152 to control the valve body to open the exhaust component before controlling the locking component 120 to open the unlocking state, thereby enriching the control mode of the transmission component 150 and realizing exhaust treatment of the cooking utensil 200 before the locking component 120 is unlocked, thereby facilitating the opening of the cooking utensil 200.

[0092] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0093] like Figure 1 , Figure 2 and Figure 3 As shown, the transmission assembly 150 has a first position and a second position. When the transmission assembly 150 is in the first position, the locking component 120 is locked with the pot body 210 . When the transmission assembly 150 is in the second position, the locking component 120 is unlocked with the pot body 210 .

[0094] In this embodiment, the transmission assembly 150 has a first position and a second position. When the transmission assembly 150 is in the first position, the driving component 162 drives the rack 152 through the gear 164, and the rack 152 moves, so that the transmission assembly 150 slides parallel to the first mounting column 112. The transmission assembly 150 drives the second mounting column 122 on the locking component 120 through the mounting hole 1524, and the locking component 120 is locked with the pot body 210. When the transmission assembly 150 is in the second position, the driving component 162 drives the rack 152 through the gear 164, and the rack 152 moves, so that the transmission assembly 150 slides parallel to the first mounting column 112 in the opposite direction. The transmission assembly 150 drives the second mounting column 122 on the locking component 120 through the mounting hole 1524, and the locking component 120 is unlocked with the pot body 210, thereby simplifying the structures of the driving component 160 and the transmission assembly 150, reducing the volume of the cover assembly 100, and reducing the production and installation cost of the cover assembly 100.

[0095] Specifically, the first position is S1 and the second position is S2.

[0096] Specifically, the transmission assembly 150 reaches the S1 position after rotating in the direction indicated by the arrow A, and controls the locking component 120 to enter the locked state. The transmission assembly 150 reaches the S2 position after rotating in the direction indicated by the arrow B, and controls the locking component 120 to enter the unlocked state.
