When the cover body is opened relative to the pot body, food can be placed in the cooking space or taken out of the cooking space.

The cover body and the cooking utensil provided by the embodiment of the utility model are described in detail below with reference to specific embodiments. As shown in fig. 1, the cover 10 may include a removable steam valve 100. The steam valve 100 may exclude steam generated in the cooking space. The steam valve 100 is of various types and is not limited herein. The steam valve 100 may have a substantially square shape, a circular shape, an elliptical shape, or the like. For example, a steam valve may provide about 1.2 times the standard atmospheric pressure for the cooking space of the cooking appliance. The cooking appliance having the cover 10 of the steam valve 100 can cook food faster than a general cooking appliance, can secure nutrition of food, and does not affect taste of food. The steam valve 100 may have a steam inlet 101 and a steam outlet 102. In general, the steam inlet 101 may communicate with the cooking space. The steam outlet 102 may be in communication with the outside. Specifically, as shown in fig. 3, the steam valve 100 may have a steam passage 103. The steam inlet 101 may communicate with the steam outlet 102 through a steam passage 103, and thus communicate with the outside. The direction of flow of the steam valve 100 is shown by the solid arrows in fig. 3.

Illustratively, in some alternative embodiments, as shown in fig. 1, the cover 10 may further include a mounting bracket 200. The steam valve 100 may be detachably mounted on the upper side of the fixing base 200 by means of a snap-in, magnetic attraction, etc., or various connection means that may occur in the future, which is not limited herein.

By providing the fixing base 200, the fixing base 200 can support the steam valve 100.

As shown in fig. 1, the cover 10 may further include a liner 600. As shown in fig. 3, the steam valve 100 may be located above the liner 600. It is understood that the steam valve 100 may be directly connected to the upper side of the liner 600, i.e., the cover 10 may not include a fixing base. The liner 600 may be provided with a first vent 601 thereon. In the installed state of the steam valve 100, the steam inlet 101 may be inserted into the first air port 601. In some embodiments, the steam inlet may be sleeved over the first vent. In other embodiments, the steam inlet may be inserted within the first vent. In this way, the high-temperature steam of the cooking space below the cover 10 may enter the steam inlet 101 through the first air vent 601, and then be discharged to the outside through the steam channel 103 and the steam outlet 102.

The steam valve 100 may have opposite first and second sides in the horizontal direction. The directional terms "first" and "second" described herein and below are used merely to distinguish between different sides and are not used to describe a particular order or sequencing. As shown in fig. 3 to 4, a detachable grip 141 may be provided on the first side 171. The detachable holding portion 141 may be any structure that can be held, such as a tab, a handle, a lug, etc., and is not limited herein.

The second side 172 may generally act as a fulcrum when the hand-held removal grip 141 removes the steam valve 100. In the case that the distance from the steam inlet 101 to the second side 172 is smaller than the distance from the steam inlet 101 to the first side 171, when the steam valve 100 is detached, the moment arm of resistance generated by the first air vent 601 to the steam inlet 101 is smaller, and on the premise that the resistance is constant, the resistance moment to be overcome is smaller. Moreover, the distance from the steam inlet 101 to the second side 172 is smaller than the distance from the steam inlet 101 to the first side 171, that is, the distance from the steam inlet 101 to the second side 172 is smaller than the distance from the steam inlet 101 to the disassembly holding part 141, that is, the force arm of the external force applied by the disassembly holding part 141 is longer, as known from the lever principle, the relatively small force applied to the disassembly holding part 141 can overcome the resistance moment, and the steam valve 100 can be disassembled. So set up, the lid 10 of this application very big has made things convenient for the user to dismantle steam valve 100 easily, labour saving and time saving. Moreover, in the process of disassembling the steam valve 100, damage to the steam valve 100 is avoided, failure of the steam valve 100 due to the disassembling process is avoided, the service life of the steam valve 100 is prolonged, the service life of the cover body 10 is prolonged, and the cover body 10 is prevented from being scalded to a certain extent due to damage of the steam valve 100.

Illustratively, as shown in FIG. 3, the first side 171 may be a rear side of the steam valve 100. The azimuthal term "rear side" as described herein and below refers to the side of the cover 10 that is remote from the user. For ease of understanding, some scenarios are described as examples. In some alternative embodiments, the operation interface of the cover 10 may be disposed on a side close to the user, and the first side 171 of the present application is a rear side of the steam valve 100, i.e., a side far from the operation interface. In this way, the user hardly moves to the area of the first side 171 during the daily cooking operation, and frequently avoids the structure near the first side 171 or is bumped by the structure near the first side 171 during the daily operation. The second side 172 may be a front side of the steam valve 100. That is, the second side 172 may be a side relatively close to the user. The detachable holding part 141 can be positioned at one side far away from the user, the user can hardly move to the area for detaching the holding part 141 in daily cooking, and the user does not need to worry about avoiding or colliding with the detachable holding part 141, so that the operation comfort level when the cover body 10 is used is improved; and the experience of the user is improved.

Illustratively, as shown in FIG. 1, the cover 10 may further include a face cover 400. The face cover 400 may be located between the holder 200 and the liner 600.

In some embodiments, the mount 200 may be attached to the face cover 400. In some embodiments, the fixing base may be connected to the liner, and the cover is provided with an avoidance space for avoiding a relevant portion of the fixing base. The fixing base 200, the cover 400 and the inner liner 600 may be mounted and connected from the same side, or may be mounted and connected at different sides, which is not limited herein.

In an alternative embodiment, as shown in fig. 5, the fixing base 200 may be provided with a first coupling hole 270. The first connection hole 270 may be a screw hole, a through hole, etc., and is not limited herein. The number of the first connection holes 270 may be one, two, or more. When the first connection holes 270 are plural, the structures of the plural first connection holes 270 may be the same or different. For convenience of processing and manufacturing, the plurality of first coupling holes 270 may be generally designed in a uniform structure. The first connection member may pass through the first connection hole 270 from above and be connected to the face cover 400. The first connector (not shown) may be a fastener or other structural connector, and is not limited herein. The number of first connection members may be identical to the number of first connection holes 270. When the number of the first connecting pieces is plural, the structures of the plural first connecting pieces may be the same or different, as long as the plural first connecting pieces can be connected with the corresponding first connecting holes in a matching manner. In this way, when the cover 10 is installed, the fixing base 200 can be connected to the cover 400 from above, and then other subsequent parts can be assembled, for example, subsequent connection with the cooker or other structures. In this way, the fixing seat 200 and the face cover 400 can form a part, and the assembly process is simple and convenient; the operation is performed from the upper side, the view angle of an operator is clear, the assembly working hour of the cover body 10 is shortened, and the production efficiency is improved.

So set up, fixing base 200 can firmly press face lid decoration 500 on face lid 400, does benefit to the whole fastness of lid 10.

Illustratively, the steam valve 100 may be provided with a light transmissive window 110 thereon. The light-transmitting window 110 may be a closed solid portion formed of a light-transmitting material, or an integral opening, and is not limited herein. As shown in fig. 1, the cover 10 may further include a display assembly 300. The display assembly 300 may display any suitable content as desired, for example, may display the operational status of some of the functional components, thereby enabling a user to more intuitively see the operational status of these components; or may display a cooking program of the cooking appliance, for example, a currently executed cooking program may be displayed; or may display the progress of the currently executed cooking program; or display different contents depending on whether the selected cooking program is to use the functional part, for example, the display assembly may display a first pattern or light up when the functional part is to be used in the currently executed cooking program, and the display assembly may display a second pattern or light out different from the first pattern when the functional part is not to be used in the currently executed cooking program; or may display a boot pattern; or a combination of the above. The display assembly 300 may be configured in a light or screen display manner known in the art, or in various other display manners that may occur in the future, without limitation. The display assembly 300 may be provided on the fixing base by means of adhesion, welding, screwing, riveting, clamping, interference fit, etc. known in the art, or various connection means which may occur in the future, which is not limited herein. The light transmissive window 110 may expose the display assembly 300.

In some alternative embodiments, as shown in fig. 1-3, the display assembly 300 may include a light emitting element 310 and a light shield 320. The light emitting element 310 may be an LED lamp, a lamp paste, or various light emitting elements that may be present in the future, which are known in the art, and are not limited herein. The light emitting element 310 may be connected to the light shield 320 by various structures. In some embodiments, the light shield 320 may be attached to the inner wall of the holder by an interference fit. The light shield 320 may laterally surround the light emitting element 310. By arranging the light shield 320, light emitted by the light emitting element 310 is prevented from being transmitted through the side surface, but is emitted along the end part of the light emitting element 310, and the influence on visual effect caused by the fact that the light of the light emitting element 310 is emitted to the periphery when the cover body 10 is arranged inside is avoided.

As shown in fig. 1-3, the display assembly 300 may further include a label plate 330. The label plate 330 may have a light transmissive target display pattern thereon. The label plate 330 may cover the top of the light shield 320. The light shield 320 may support the label plate 330. As can be seen from the foregoing, the light-emitting element may be surrounded by the light-shielding cover 320 from the side, i.e. the light-emitting element is located inside the light-shielding cover or at the bottom of the light-shielding cover, and the label plate 330 is located above the light-emitting element. Thus, the light emitted from the light emitting element can be projected out of the cover 10 through the target display pattern. Thus, by providing the label plate, the cover 10 can present the target display pattern on the light-transmitting window 110 through the light-emitting element, enriching the display state of the cover 10; the aesthetic degree of the cover body 10 is improved; and the experience of the user is improved.

Regardless of the structure of the display assembly, the contents displayed by the display assembly may be displayed on the outer surface of the cover 10 through the light-transmitting window 110. By arranging the light-transmitting window 110 and the display component, the experience of the user is improved; moreover, the light-transmitting window 110 is also convenient for timely finding whether the display assembly displays normal or fails, so that the display assembly can be maintained and replaced timely. In addition, through setting up the display module around steam valve 100, can remind the position of user steam valve 100 to a certain extent, prevent that high temperature steam from scalding the user.

For example, the air inlet 101 may be located between the display assembly 300 and the second side 172. So configured, the air inlet 101 may be relatively closer to the second side 172, which may correspond to a reduction in the distance between the air inlet 101 and the second side 172, facilitating a smaller distance of the steam inlet 101 to the second side 172 than the steam inlet 101 to the first side 171.

Illustratively, as shown in fig. 3 and 5, the mount 200 may include an upwardly raised ridge 240. The ridge may be generally cubic, cylindrical, or other structure, without limitation. The display assembly may be disposed within the boss 240. In this way, the ridge 240 may conceal the display assembly located therein, providing some protection. At least the portion of the top wall of the ridge 240 exposed by the light-transmitting window 110 is light-permeable. It is understood that the ridge 240 may be entirely transparent. The contents displayed by the display assembly may be presented on the outer surface of the cover 10 sequentially through the portion of the top wall of the ridge 240, the light-transmitting window 110 (i.e., the hollow space) of the steam valve 100. By the arrangement, the bulge part 240 can play a certain role in protecting the display assembly, so that the display assembly is prevented from being knocked or broken by foreign objects, and the service life of the display assembly is prolonged; moreover, the part of the top wall of the bulge part 240, which is at least exposed by the light-transmitting window 110, is light-permeable, so that a user can directly observe the display content of the display assembly through the light-transmitting window 110, the comfort and convenience in using the cover body 10 are improved, and the experience of the user is improved.

Illustratively, as shown in FIG. 8, the steam valve 100 may include a lower valve cover 120 and an upper valve cover 130. The valve lower cover 120 and the valve upper cover 130 may surround to form the steam channel 103. In some alternative embodiments, a first seal 151 may be provided between the lower valve cover 120 and the upper valve cover 130. In this way, the steam channel 103 can have good sealing performance, and steam entering the steam channel 103 is prevented from leaking out through the connection part. The steam channel 103 communicates between the steam inlet 101 and the steam outlet 102. The valve lower cover 120 may be provided with a first through hole 121. The valve upper cover 130 may be provided with a second through hole 131. The second through hole 131 is aligned with the first through hole 121. The bump 240 may extend to the second through hole 131 via the first through hole 121. As such, the top wall of the ridge 240 may be substantially flush with the edge of the second through hole 131. That is, the second through hole 131 of the steam valve 100 may be substantially flush with the top wall of the raised portion 240 of the fixing base 200, so that the steam valve 100 has a better visual feel at the second through hole 131, which corresponds to beautifying the structure of the steam valve 100 and improving the experience of the user. So set up, the bump 240 can stretch into the steam valve 100 through the first through hole 121, is equivalent to shortening the distance between the top wall of the bump 240 and the valve upper cover 130, and further makes the top wall of the bump 240 be closer to the light transmission window 110 of the steam valve 100, shortens the distance from the display assembly 300 to the light transmission window 110, and improves the display effect of the display assembly 300 observed through the light transmission window 110. The protrusion 240 protruding into the steam valve 100 may reduce the overall height of the holder 200 and the steam valve 100. In addition, the structure of the steam valve 100 is beautified, and the experience of the user is improved.

Illustratively, as shown in fig. 8, the valve lower cover 120 may be provided with an annular flange 122 extending upward from an edge of the first through hole 121. The annular flange 122 may surround the sides of the ridge 240. So configured, the annular flange 122 can radially limit the sides of the ridge 240 to a degree that avoids extensive displacement of the ridge 240 within the steam valve 100. Moreover, the bulge 240 may have a relatively independent space in the steam valve 100, and the annular flange 122 protects the bulge 240, and is also convenient for directly removing the space when designing the steam channel 103 and setting the steam channel 103 outside the space, so that the structure of the steam valve 100 can be simplified to a certain extent, and the design scheme of the cover 10 is simplified.

Illustratively, as shown in fig. 8, the top of the annular flange 122 may be inserted into the second through hole 131. A space is provided between the annular flange 122 and the inner side wall of the second through hole 131. The space may form the air outlet 102 of the steam channel 103. So configured, the air outlet 102 of the steam channel 103 may have a ring-shaped structure. Compared with the form that a whole air is directly discharged in an annular column shape from an annular air outlet, the air entering the steam valve 100 can be guided to the annular air outlet 102 to be discharged, so that the air flow of the air outlet 102 can be greatly dispersed, and the air outlet 102 of the steam channel 103 is prevented from scalding a user; moreover, the air outlet 102 of the steam channel 103 is annular, which can also improve the steam aesthetic degree of the steam valve 100.

For example, as shown in fig. 8, the steam inlet 101 may be provided on the valve lower cover 120. By the arrangement, steam can flow from the valve lower cover 120 to the steam channel 103 formed by surrounding the valve upper cover 130, and the movement rule of the steam flowing upwards in a natural state is consistent, so that the flow of the steam in the steam valve 100 can be quickened, and the exhaust effect of the steam valve 100 is improved to a certain extent; thereby improving the performance of the cover 10.

Illustratively, as shown in FIG. 8, the steam valve 100 may include a valve housing 140. The valve housing 140 may be snapped onto the upper surface of the valve upper cover 130. In some alternative embodiments, a second seal 160 may be provided between the valve housing 140 and the valve cover 130. In this way, the steam channel 103 can have good sealing performance, and steam entering the steam channel 103 is prevented from leaking out through the connection part. The light-transmitting window 110 may be provided at the valve housing 140. It is understood that the light transmissive window 110 may be provided on a side wall, top wall of the valve housing 140. In some embodiments, not shown, the light-transmitting window may be provided on a sidewall of the valve housing, and may be provided in a certain area. Alternatively, the light-transmitting window may be disposed on the side wall so as to extend along the circumferential direction, i.e., form an annular light-transmitting window. Alternatively, the light-transmitting window may be provided in an edge region of the top wall of the valve housing. The light-transmitting window 110 may have various shapes, and may be in the shape of a discrete star, a petal, or a coherent integral light-transmitting window, none of which are limited herein. In general, the valve upper cover 130 and the valve lower cover 120 need to have better sealing performance after being matched, which makes the machining precision of the valve upper cover 130 and the valve lower cover 120 higher in the machining process, and the machining precision is higher than that of the valve housing 140 in most cases. Thus, the light-transmitting window 110 can be directly processed on the valve outer cover 140, so that the light-transmitting window 110 is prevented from being processed and manufactured on the valve body formed by the valve upper cover 130 and the valve lower cover 120, and the manufacturing complexity of the steam valve 100 is reduced. The valve housing 140 protects the valve body formed by the valve upper cover 130 and the valve lower cover 120, and also improves the aesthetic appearance of the steam valve 100 to some extent. The valve housing 140 may be transparent.

For example, as shown in fig. 5, the fixing base 200 may be provided with a second ventilation opening 252. As shown in fig. 3, the second vent 252 may be aligned with the first vent 601. In some alternative embodiments, as shown in fig. 6, in embodiments in which the cover 10 includes a face cover 400, the face cover 400 may be provided with relief holes 450. The second ventilation opening 252 provided on the fixing base 200 may pass through the avoidance hole 450. In this way, the second ventilation openings 252 may pass through the face cover 400 to corresponding locations of the liner 600. The steam inlet 101 may extend downward from the bottom surface of the steam valve 100. The steam inlet 101 can be connected to the first air opening 601 in a plug-in manner through the second air opening 252. In this way, the high temperature steam generated in the cooking space under the liner 600 may enter the steam inlet 101 through the first air vent 601, thereby being discharged to the outside. So configured, the cooking space below the liner 600 may have a communication external air passage with the outside. Moreover, the gas channel can be realized through the internal structure without any additional connecting pipe, so that the exhaust channel of the cover body 10 has a simple structure, the number of the whole parts of the cover body 10 is reduced, and the probability of failure of the cover body 10 is reduced. In terms of the related aspect of sealing, if the steam inlet 101, the second air port 252 and the first air port 601 are connected in series in order, the connection between the steam inlet 101 and the second air port 252 and the connection between the second air port 252 and the first air port 601 need to be sealed respectively, and two positions need to be sealed. The air inlet 101 of the steam valve 100 is inserted into the first air vent 601, so that the part between the steam air inlet 101 and the first air vent 601 can be sealed, the number of parts needing to be sealed is reduced, the number of parts of the cover body 10 on a high-temperature steam flowing path is reduced, and the process and manufacturing difficulty is reduced; the number and frequency of replacement of related seals is also reduced, reducing the number of wearing parts and thus reducing maintenance costs.

For example, as shown in fig. 3, a sealing ring 280 may be sandwiched between an edge of the second vent 252 and an edge of the first vent 601. In the installed state of the steam valve 100, the sealing ring 280 may seal between the steam inlet 101 and the first air vent 601. So set up, sealing washer 280 can seal steam inlet 101, avoids high temperature steam to leak to the inside of lid 10 through the space between steam inlet 101 and the first air vent 601 to the performance of internal circuit components and parts or other spare part has been influenced.

For example, as shown in fig. 1 and 3, the steam valve 100 is in a mounted state, and the steam inlet 101 may be inserted into the first air port 601. As shown in fig. 3, a sealing ring 280 may be provided between the outer sidewall of the steam inlet 101 and the inner sidewall of the first air vent 601. In this way, the steam valve 100 may be inserted onto the liner 600, and gas of the cooking space under the liner 600 may enter the steam valve 100 through the first vent 601. Moreover, the sealing ring 280 can seal the joint between the liner 600 and the steam valve 100, so as to prevent the gas in the cooking space below the liner 600 from entering the surface cover 400 or other internal space of the cover body 10 through the gap at the joint between the liner 600 and the steam valve, and prevent the electronic components in the internal space from being damaged due to the action of the leaked gas. A protrusion 150 may be provided on the outer sidewall of the steam inlet 101. The protrusion 150 may have various shapes such as trapezoid, circle, square, etc., and is not limited herein. The protrusion 150 and the outer sidewall of the steam inlet 101 may be integrally formed or separately formed and then coupled together, which is not limited herein. The number of protrusions 150 may be one, two, or more. When the number of the protrusions 150 is plural, the protrusions 150 may be disposed around the steam inlet 101, which is not limited herein. The protrusion 150 may press the sealing ring 280 in a radial direction of the steam inlet 101. By means of the arrangement, the protrusion 150 can apply a certain extrusion force to the sealing ring 280 along the radial direction of the steam inlet 101, namely, the friction force between the protrusion and the sealing ring can be increased, the sealing ring 280 can be tightly attached to the side wall of the steam inlet 101 by the friction force generated by extrusion, and the steam valve 100 can be effectively prevented from loosening in the direction perpendicular to the radial direction, for example, the steam valve 100 is prevented from being separated from the fixing seat 200 in the process of overturning the cover body 10; moreover, this structure can improve the sealing effect of the seal ring 280 at the pressing position to some extent. Moreover, the sealing ring 280 can seal the joint between the liner 600 and the steam valve 100, so as to prevent the electronic components inside the cover 10 from being damaged due to gas leakage.

Illustratively, the protrusions may be plural and spaced apart along the circumferential direction of the steam inlet 101. The spacing distribution may be uniform, or non-uniform. So set up, a plurality of archs can extrude sealing washer 280 in a plurality of positions, have increased protruding total extrusion force to sealing washer 280 extruded to still further improve steam valve 100's connection fastness, still further avoid its pine to take off in the use. Moreover, along the circumference direction interval distribution of steam air inlet 101, be equivalent to a plurality of archs and can encircle a whole circle of sealing washer 280, promptly, the arch can all extrude at the whole circumference of sealing washer 280, and steam air inlet 101 is more firm with the connection of sealing washer 280, avoids both firm in connection and the not hard up phenomenon of opposite side in a certain side.
