Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and more particularly, to a cooking appliance. Background Art

[0002] Known cooking appliances (such as rice cookers) usually have a large heating power in order to improve the cooking rate. However, during actual use, when the ingredients are continuously heated to boiling with high heat, a large amount of foam will be generated, resulting in the problem of overflowing the pot.

[0003] Related technologies avoid overflowing the pot by introducing cold air into the cooking space. However, the introduced cold air will inevitably be mixed with sundries such as lampblack in the kitchen environment. Over time, oil stains or dirt will remain in the gas pipeline, thus affecting the taste of the food, and it is also possible to cause the gas pipeline to be blocked, affecting the introduction of cold air.

[0004] Therefore, it is necessary to propose a cooking appliance to at least partially solve the problems existing in the prior art. Summary of the Invention

[0005] A series of simplified concepts are introduced in the Summary of the Invention section, which will be further described in detail in the Detailed Description section. The Summary of the Invention section of the present invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0006] The present invention provides a cooking appliance. The cooking appliance includes a pot body, a lid body, an air inlet, and a gas delivery device. An inner pot is provided in the pot body. The lid body is movably provided on the pot body. When the lid body covers the pot body, a cooking space is formed between the lid body and the inner pot. The lid body is provided with an air suction port for sucking in external gas and a steam outlet for discharging steam. The air inlet is communicated with the cooking space. The gas delivery device is communicated with the air inlet through an air inlet pipeline and is communicated with the air suction port through an air suction pipeline. Wherein, the steam outlet is arranged around the air suction port.

[0007] In the cooking appliance according to the present invention, during the cooking process, when the food in the food storage space of the cooking space is in the boiling stage, the gas delivery device can inhale gas through the air intake and deliver the gas to the cavity space of the cooking space through the air inlet. Generally, there is a temperature difference between the gas being delivered and the foam in the cavity space. Therefore, after the gas being delivered enters the cavity space and contacts the foam accumulated in the cavity space, it can cause the steam in the foam to liquefy, contract, and break, so as to prevent the pot from overflowing. Even in the case of rapid cooking with high heat, the pot can be prevented from overflowing. In addition, since the steam outlet is arranged around the air intake, the steam discharged through the steam outlet will form a circumferentially continuous or closed steam curtain around and above the air intake to filter the gas inhaled into the air intake, avoiding the inhalation of sundries such as oil fumes and dust into the air intake, thus avoiding the accumulation of oil stains or dirt or even blockage in the gas pipeline and also avoiding affecting the taste of the food.

[0008] Optionally, the steam outlet is annular, or the steam outlet includes a plurality of sub-steam outlets arranged at intervals along the circumferential direction of the steam outlet.

[0009] Optionally, the distance between the steam outlet and the air intake is less than or equal to 60 mm. When the distance between the steam outlet and the air intake is within the above range, the steam at the steam outlet forms a circumferentially continuous steam curtain around the air intake.

[0010] Optionally, the distance between the steam outlet and the air intake is greater than or equal to 10 mm and less than or equal to 25 mm. When the distance between the steam outlet and the air intake is within the above range, not only can the steam at the steam outlet form a circumferentially continuous steam curtain around the air intake, but also the air intake can be prevented from inhaling part of the steam.

[0011] Optionally, the gas delivery device is an air pump.

[0012] Optionally, the air pump flow rate of the air pump is greater than or equal to 0.3 LPM and less than or equal to 12 LPM. When the air pump flow rate is within the above range, it is convenient to install the air pump in medium and small household appliances such as cooking appliances and achieve a good anti-overflow effect.

[0013] Optionally, the air pump flow rate of the air pump is greater than or equal to 0.5 LPM and less than or equal to 6 LPM. When the air pump flow rate is within the above range, it is convenient to install the air pump in medium and small household appliances such as cooking appliances and achieve a good anti-overflow effect.

[0014] Optionally, the area of the steam outlet is greater than or equal to 100 mm 2 and less than or equal to 800 mm 2In this way, it is convenient to form a circumferentially continuous steam curtain around the air inlet.

[0015] Optionally, the area of the steam outlet is greater than or equal to 150 mm 2 and less than or equal to 650 mm 2 In this way, it is convenient to form a circumferentially continuous steam curtain around the air inlet.

[0016] Optionally, the cover body includes a lining cover, a steam valve assembly, and a decorative cover disposed on the upper sides of the lining cover and the steam valve assembly. The steam valve assembly is disposed on the lining cover, and the air inlet and the steam outlet are disposed on the decorative cover.

[0017] Optionally, the cover body includes a lining cover and a steam valve assembly. The steam valve assembly is detachably mounted to the lining cover, and the air inlet and the steam outlet are disposed on the steam valve assembly.

[0018] Optionally, the air intake pipeline includes a first air intake pipeline disposed in the steam valve assembly and a second air intake pipeline disposed in the lining cover. The second air intake pipeline is connected to the gas delivery device. Both ends of the first air intake pipeline are communicated with the air inlet and the second air intake pipeline respectively. A first seal is disposed between the steam valve assembly and the lining cover. In this way, it is convenient to detach the steam valve assembly for cleaning, and it can also prevent gas from entering the second air intake pipeline through the gap between the steam valve assembly and the lining cover without passing through the steam filter at the steam outlet and finally entering the cavity space.

[0019] Optionally, the steam valve assembly includes a steam valve base, a steam valve, a steam valve upper cover, and a second seal. The steam valve base is detachably mounted to the lining cover. The first air intake pipeline is disposed in the steam valve base. The first seal is disposed between the steam valve base and the lining cover. The steam valve is disposed on the steam valve base. The steam valve upper cover is detachably mounted to the steam valve base. The second seal is disposed between the steam valve upper cover and the steam valve base. In this way, it is convenient to detach the steam valve upper cover from the steam valve base for cleaning. At the same time, the second seal can prevent the steam in the steam channel from entering the first air intake pipeline in the steam valve base through the gap between the steam valve upper cover and the steam valve base.

[0020] Optionally, the steam valve assembly includes a steam valve decorative cover located on the outer surface of the steam valve assembly. The air intake pipeline includes a first end communicated with the air inlet and a second end connected to the gas delivery device. The steam valve decorative cover covers the first end of the air intake pipeline. In this way, it is possible to prevent the upper end of the air intake pipeline from being directly exposed outside, and prevent other sundries (such as water, cockroaches, etc.) from entering the air intake pipeline.

[0021] Optionally, the air inlet is disposed on the steam valve decorative cover. The projection of the first end of the air suction pipeline on the steam valve decorative cover is spaced apart from the air inlet. The steam valve assembly further includes a protruding portion protruding downward from the steam valve decorative cover, and the protruding portion is located between the air inlet and the first end of the air suction pipeline. In this way, it is possible to further ensure that other sundries do not enter the air suction pipeline together with the outside air, avoiding blockage of the air suction pipeline.

[0022] Optionally, the horizontal distance between the inner side wall of the protruding portion and the outer side wall of the first end of the air suction pipeline is greater than or equal to 1 mm. In this way, the adhesion of water can be avoided, ensuring the communication between the air inlet and the air suction pipeline.

[0023] Optionally, the lowermost end of the protruding portion is lower than the first end of the air suction pipeline. In this way, it can be ensured that other sundries do not enter the air suction pipeline together with the outside air due to gravity and block the air suction pipeline.

[0024] Optionally, the cover body includes a boss at least partially located between the air inlet and the steam outlet. A steam outlet surface is formed between the boss and the steam outlet, and the boss is higher than the steam outlet surface. In this way, under the action of gravity, the condensed water will gather on the steam outlet surface between the steam outlet and the boss, and will not enter the air inlet across the boss.

[0025] Optionally, the air inlet is disposed on the boss. In this way, under the action of gravity, the condensed water will gather between the steam outlet and the boss, and will not enter the air inlet disposed on the boss. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other instances, some well-known technical features are not described to avoid confusion with the present invention.

[0034] To thoroughly understand the present invention, detailed structures will be presented in the following description to illustrate the present invention. Obviously, the implementation of the present invention is not limited to the specific details familiar to those skilled in the art of this technology. The preferred embodiments of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention can also have other implementation manners and should not be construed as limited to the embodiments presented here.

[0035] The present invention provides a cooking appliance and its lid. The cooking appliance can be a rice cooker, an electric pressure cooker, or other electric heating appliances. In addition, in addition to the function of cooking rice, the cooking appliance can also have other functions such as cooking porridge and making soup.

[0036] Figure 1 shows a schematic diagram of the principle of a cooking appliance 100 according to an embodiment of the present invention. Among them, for simplicity, Figure 1 only a part of the structure of the cooking appliance 100 is schematically shown in.

[0037] As Figure 1 shown, the cooking appliance 100 includes a pot body 110. The pot body 110 can be in a generally rounded rectangular parallelepiped shape, a generally cylindrical shape, or any other suitable shape. An inner pot 130 in a generally cylindrical shape or any other suitable shape is provided in the pot body 110. The inner pot 130 can be freely placed into or taken out from the inner pot storage portion of the pot body 110 to facilitate cleaning of the inner pot 130. The inner pot 130 is used to store food to be cooked, such as rice, soup, etc. The top of the inner pot 130 has a top opening. The user can store the food to be cooked in the inner pot 130 through the top opening, or take out the cooked food from the inner pot 130 through the top opening.

[0038] The pot body 110 is also provided with an inner pot heating device (not shown) for heating the inner pot 130. The inner pot heating device can heat the inner pot 130 at the bottom and / or side of the inner pot 130. The inner pot heating device can be an electric heating tube or an induction heating device such as an electromagnetic coil.

[0039] As Figure 1 shown, a lid body 120 is provided on the pot body 110. The shape of the lid body 120 basically corresponds to the shape of the pot body 110. For example, the lid body 120 can be in the shape of a rounded cuboid. The lid body 120 is provided on the pot body 110 in an openable and closable manner for covering the entire top of the pot body 110 or at least the inner pot 130 of the pot body 110. Specifically, in this embodiment, the lid body 120 can be pivotally provided above the pot body 110 between a maximum open position and a closed position, for example, by means of a hinge. The hinge position between the lid body 120 and the pot body 110 is usually located at the rear end of the cooking appliance 100 to facilitate the user's operation at the front end of the cooking appliance 100. It should be noted that the "front" and "rear" referred to in this article are based on the position where the user uses the cooking appliance. Specifically, the direction in which the cooking appliance faces the user is defined as "front", and the opposite direction is defined as "rear".

[0040] As Figure 1 shown, when the lid body 120 covers the pot body 110, a cooking space 140 is formed between the lid body 120 and the pot body 110 (specifically, with the inner pot 130 of the pot body 110). The cooking space 140 includes a food storage space 141 and a cavity space 142. Specifically, the food storage space 141 refers to the space where food is actually stored. The cavity space 142 is located above the food storage space 141. That is, when the lid body 120 covers the pot body 110, the cavity space 142 is the space between the upper surface of the food and the lid body 120. There is no strict dividing line between the food storage space 141 and the cavity space 142, and the volume sizes of the two will change according to the specific changes in the volume of the ingredients.

[0041] As Figure 1 shown, the lid body 120 is provided with one or more air intake ports 151. One end of the air intake port 151 is communicated with the outside, and the other end is communicated with a gas delivery device 153 (more specifically, the intake end of the gas delivery device 153) provided in the pot body 110 or the lid body 120 to be described in detail below, so as to deliver outside gas (such as cold air) to the cooking space 140 (more specifically, the cavity space 142) through the gas delivery device 153.

[0042] Specifically, in one embodiment of the present invention, as Figure 2 and Figure 5As shown, the cover body 120 includes a lining cover 121. A lining cover decorative cover 122A is provided on the upper side or the outer side of the lining cover 121. An inner cover 123 is provided on the lower side or the inner side of the lining cover 121. The inner cover 123 can be a detachable inner cover to facilitate the removal of the inner cover 123 for cleaning. The cover body 120 further includes a steam valve assembly. The steam valve assembly is provided on the lining cover 121 or detachably mounted to the lining cover 121. A steam valve decorative cover 122B is provided on the upper side or the upper surface of the steam valve assembly. When the steam valve assembly is detachably mounted to the lining cover 121, the lining cover decorative cover 122A and the steam valve decorative cover 122B are separate components. When the steam valve assembly is provided on the lining cover 121, the lining cover decorative cover 122A and the steam valve decorative cover 122B are integral components. The lining cover decorative cover 122A and the steam valve decorative cover 122B together constitute the decorative cover of the cover body 120. An air inlet 151 is provided on the steam valve assembly. More specifically, in an embodiment of the present invention, the air inlet 151 is provided on the steam valve decorative cover 122B. It should be noted that when the steam valve assembly is provided on the lining cover 121, since the steam valve decorative cover 122B and the lining cover decorative cover 122A are an integral decorative cover, the air inlet 151 can be considered to be provided on the decorative cover of the cover body 120. Of course, the air inlet 151 can also be provided at any other suitable position of the cover body 120. For example, the air inlet 151 can be provided on the side of the cover body 120.

[0043] It should be noted that the directional terms and positional relationship terms used in this article to describe the various components and their positional relationships in the cover body 120, such as "above", "below", "upper side", "lower side", "upward", "downward", "above", "below", "high", "low", "horizontal distance", etc. are relative to the cover body 120 when it is in the closed position.

[0044] An air inlet 152 communicating with the cavity space 142 is further provided in the cooking appliance 100. The air inlet 152 can be provided at any suitable position of the cooking appliance 100. Specifically, in an embodiment of the present invention, the air inlet 152 is provided on the cover body 120. More specifically, as Figure 5 shown, the air inlet 152 is provided on the inner cover 123 of the cover body 120. Of course, the air inlet 152 can also be provided in the pot body 110 of the cooking appliance 100. For example, the air inlet 152 can be provided on the inner pot 130 of the pot body 110. As Figure 5 shown, a dispersion cover 170 can also be provided at the air inlet 152, and the dispersion cover 170 covers the air inlet 152. The dispersion cover 170 is provided with one or more dispersion cover through holes 171 to change the direction of the gas entering the cavity space 142 or to prevent the gas from spraying concentratedly into the cavity space 142 and blowing pits on the surface of the cooked food.

[0045] The cooking appliance 100 is further provided with a gas delivery device 153. The gas delivery device 153 is in communication with the suction port 151 and the air inlet 152. Specifically, the gas delivery device 153 is in communication with the suction port 151 through a suction pipeline 154. The first end of the suction pipeline 154 is in communication with the suction port 151, and the second end of the suction pipeline 154 is connected to the gas delivery device 153 (specifically, the air inlet end of the gas delivery device 153). For example, the suction pipeline 154 can be made of an elastic material such as silica gel. The first end of the suction pipeline 154 is inserted into the suction port 151, and the second end of the suction pipeline 154 is inserted into the air inlet end of the gas delivery device 153. It can be understood that when the gas delivery device 153 is located in the pot body 110, a part of the suction pipeline 154 extends into the pot body 110 to be connected to the gas delivery device 153 provided in the pot body 110. The gas delivery device 153 is in communication with the air inlet 152 through an air inlet pipeline 155. One end of the air inlet pipeline 155 is in communication with the air inlet 152, and the other end is connected to the gas delivery device 153. For example, the air inlet pipeline 155 can be made of an elastic material such as silica gel. One end of the air inlet pipeline 155 is inserted into the air inlet 152, and the other end is inserted into the air outlet end of the gas delivery device 153. Therefore, the suction port 151, the suction pipeline 154, the gas delivery device 153, the air inlet pipeline 155, and the air inlet 152 together form a gas delivery system for sucking the gas outside the cooking appliance 100 (such as the outside cold air) into the cavity space 142.

[0046] During the cooking process, when the food in the food storage space 141 is in the boiling stage, viscous substances such as starch in the cooked food will precipitate into the water, and the steam is wrapped to form a large amount of foam. These foams will accumulate in a large amount in the cavity space 142 above the food storage space 141. The gas delivery device 153 can suck gas from the suction port 151 and deliver the sucked gas into the cavity space 142 through the air inlet 152. Usually, there is a temperature difference between the gas delivered and the foam in the cavity space 142. Therefore, after the delivered gas enters the cavity space 142 and contacts the foam accumulated in the cavity space 142, it can liquefy and shrink the steam in the foam and break it to prevent the pot from overflowing. Even in the case of rapid cooking with high heat, the pot can be prevented from overflowing.

[0047] As Figures 1 to 2As described above, the lid 120 is further provided with a steam outlet 182 for discharging steam. Specifically, the steam outlet 182 is provided on the steam valve assembly. More specifically, the steam outlet 182 is provided on the steam valve decorative cover 122B. It should be noted that when the steam valve assembly is provided on the liner cover 121, since the steam valve decorative cover 122B and the liner cover decorative cover 122A are an integral decorative cover, the steam outlet 182 can be considered to be provided on the decorative cover of the lid 120. The steam outlet 182 communicates with the steam inlet 181 through the steam channel 180. The steam inlet 181 communicates with the cavity space 142. The steam inlet 181 can be provided on the inner lid 123. Of course, the steam outlet 182 and the steam inlet 181 can also be provided at any other suitable positions on the lid 120. For example, the steam outlet 182 can be provided on the side of the lid 120. In the lid 120 without the inner lid 123, the steam inlet 181 can also be directly provided on the liner cover 121.

[0048] As described above, after the gas transported by the gas transport device 153 enters the cavity space 142, it can liquefy, shrink and break the steam in the foam accumulated in the cavity space 142. After the transported gas impacts the foam, it can be discharged to the outside together with the steam or in the form of steam through the steam inlet 181, the steam channel 180 and the steam outlet 182, taking away part of the heat, thus being able to inhibit the generation of foam and being able to reduce the pressure to further prevent the pot from overflowing.

[0049] According to the concept of the present invention, as Figures 1 to 4 shown, the steam outlet 182 is arranged around the suction port 151. That is, the steam outlet 182 is arranged around the suction port 151. During the operation of the cooking appliance 100, when the food in the food storage space 141 is in the boiling stage, a large amount of steam will be generated in the cavity space 142, and these steams will be discharged through the steam inlet 181, the steam channel 180 and the steam outlet 182. At the same time, as described above, the gas transport device 153 also starts to work to suck gas from the suction port 151 and transport the sucked gas to the cavity space 142 through the air inlet 152. Since the steam outlet 182 is arranged around the suction port 151, the steam discharged through the steam outlet 182 will form a circumferentially continuous or closed steam curtain around and above the suction port 151 to filter the gas sucked into the suction port 151, avoiding the suction of sundries such as oil fume and dust into the suction port 151, thus avoiding the presence of oil stains or dirt or even blockage in the gas pipeline and also avoiding affecting the taste of the food.

[0050] Specifically, in an embodiment of the present invention, as Figure 3As shown, the steam outlet 182 is arranged around the air inlet 151. The steam outlet 182 includes a plurality of (such as 2, 3 or more) sub-steam outlets spaced at intervals in its circumferential direction. The plurality of sub-steam outlets can be spaced at equal distances or at unequal distances. The sub-steam outlets can be in any suitable shape such as an arc, a circle, a rectangle, etc. The shapes of the plurality of sub-steam outlets can be the same or different.

[0051] In another embodiment of the present invention, as Figure 4 shown, the steam outlet 282 is configured as an annular shape closed in the circumferential direction, which surrounds the air inlet 151. It should be noted that the "annular shape" referred to herein means any suitable shape that is closed or connected end to end in the circumferential direction and is hollow, and its outer contour can be any suitable shape such as a circle, a rectangle, a pentagon, a hexagon, etc.

[0052] The applicant has found that the distance L between the steam outlet 182 and the air inlet 151 will affect the filtering effect on the gas inhaled by the air inlet 151. When the distance L between the steam outlet 182 and the air inlet 151 is too small, since the steam outlet 182 and the air inlet 151 are too close, a part of the steam discharged from the steam outlet 182 will also be inhaled by the air inlet 151, affecting the cooling and anti-overflow effects. When the distance L between the steam outlet 182 and the air inlet 151 is too large, it may cause the steam curtain generated by the steam discharged from the steam outlet 182 around the air inlet 151 to be discontinuous in the circumferential direction or have a low concentration, weakening the filtering effect of the steam on the gas inhaled by the air inlet 151.

[0053] Preferably, in one embodiment of the present invention, the distance L between the steam outlet 182 and the air inlet 151 is less than or equal to 60 mm. Further preferably, the distance L between the steam outlet 182 and the air inlet 151 is greater than or equal to 10 mm and less than or equal to 25 mm. The applicant has found that when the distance L between the steam outlet 182 and the air inlet 151 is within the above range, not only can the steam at the steam outlet 182 form a circumferentially continuous steam curtain around the air inlet 151, but also the air inlet 151 can be prevented from inhaling part of the steam.

[0054] In addition, the applicant has also found that the area of the steam outlet 182 and the flow rate of the gas delivery device 153 will affect the formation of the steam curtain around the air inlet 151. When the area of the steam outlet 182 is large, the gas delivery device 153 needs a sufficiently large flow rate to ensure that the steam at the steam outlet 182 can form a circumferentially continuous steam curtain around the air inlet 151.

[0055] Optionally, in an embodiment of the present invention, the gas delivery device 153 is an air pump. The air pump flow rate (no-load) of the air pump is preferably greater than or equal to 0.3 LPM and less than or equal to 12 LPM. Further preferably, the air pump flow rate (no-load) of the air pump is greater than or equal to 0.5 LPM and less than or equal to 6 LPM, so as to be easily installed in medium and small household appliances such as the cooking appliance 100 and achieve a better anti-overflow effect. Correspondingly, the area of the steam outlet 182 is greater than or equal to 100 mm 2 and less than or equal to 800 mm 2 . Preferably, the area of the steam outlet 182 is greater than or equal to 150 mm 2 and less than or equal to 650 mm 2 . It should be noted that the "area" mentioned here refers to the actual total exhaust area. The applicant has found that when the air pump flow rate and the area of the steam outlet 182 are within the above ranges, it is convenient to form a circumferentially continuous steam curtain around the suction port 151.

[0056] The gas delivery device 153 can be arranged at any suitable position of the cooking appliance 100. In an embodiment of the present invention, as Figure 5 shown, the gas delivery device 153 is arranged in the lid 120, so as to be communicated with the suction port 151 arranged in the lid 120 through the suction pipeline 154 and communicated with the air inlet 152 arranged in the lid 120 through the air inlet pipeline 155. Specifically, in an embodiment of the present invention, a receiving space for accommodating the gas delivery device 153 and / or other components is formed between the lining lid 121 and the decorative lid (specifically, the lining lid decorative lid 122A). Specifically, the lining lid 121 is formed with a downwardly recessed portion, and this recessed portion forms the receiving space. The gas delivery device 153 is arranged in the receiving space. In this way, the structure of the lid 120 can be made more compact.

[0057] The gas delivery device 153 is disposed in the accommodation space through a bracket and is spaced apart from the lining cover 121 and the decorative cover, thereby preventing the gas delivery device 153 from directly contacting the lining cover 121 and the decorative cover during operation and generating noise. More specifically, the bracket may include a support portion and a fixing portion. The fixing portion is connected to the lining cover 121. The fixing portion can be fixed to the lining cover 121 by any suitable means such as threaded fasteners, adhesives, etc. The support portion is connected to the fixing portion. The support portion and the fixing portion may be an integral member or a separate member. The support portion is spaced apart from the lining cover 121 and the decorative cover, so that when the gas delivery device 153 is supported by the support portion, the gas delivery device 153 is spaced apart from the lining cover 121 and the decorative cover. That is, the gas delivery device 153 does not directly contact the lining cover 121 and the decorative cover, so as to prevent the gas delivery device 153 from directly contacting the lining cover 121 and the decorative cover during operation and generating noise. In the illustrated embodiment, the bracket is configured in a "Ω" shape. It should be noted that the shape of the bracket is not limited to the illustrated embodiment. For example, in other embodiments of the present invention, the support portion of the bracket may be annular, so that the gas delivery device 153 can be directly supported on the support portion by passing through the support portion, which facilitates the installation of the gas delivery device 153.

[0058] In an embodiment not shown in the present invention, the gas delivery device 153 may also be disposed in the pot body to prevent the ambient temperature around the gas delivery device from being too high due to steam focusing on the lower side of the cover body when the gas delivery device is disposed in the cover body, which affects the service life of the gas delivery device and increases the use cost. It should be noted that when the gas delivery device 153 is disposed in the pot body 110, the suction pipeline 154 may extend from the pivot connection between the cover body 120 and the pot body 110 into the pot body 110. Conversely, the intake pipeline 155 may extend from the pivot connection between the pot body 110 and the cover body 120 into the cover body 120.

[0059] As described above, a steam valve assembly is provided in the cover body 120. Specifically, in an embodiment of the present invention, the steam valve assembly is detachably mounted to the lining cover 121. As Figure 5 and Figure 6 shown, the first end of the suction pipeline 154, that is, the end communicating with the suction port 151, is located in the steam valve assembly to facilitate the connection between the suction pipeline 154 and the suction port 151 provided on the steam valve assembly.

[0060] Specifically, the intake pipeline 154 includes a first intake pipeline 154A and a second intake pipeline 154B. The first intake pipeline 154A and the second intake pipeline 154B are separate components. The first intake pipeline 154A is disposed in the steam valve assembly. The second intake pipeline 154B is disposed in the liner 121. Both ends of the first intake pipeline 154A are respectively communicated with the intake port 151 and the second intake pipeline 151B. Specifically, the first end of the first intake pipeline 154A is communicated with the intake port 151, and the second end of the first intake pipeline 154A is communicated with the second intake pipeline 154B. For example, the second end of the first intake pipeline 154A can be inserted into the second intake pipeline 154B. The gas inhaled through the intake port 151 reaches the gas delivery device 153 via the first intake pipeline 154A and the second intake pipeline 154B, and enters the cavity space through the intake pipeline 155. Since the first intake pipeline 154A disposed in the steam valve assembly and the second intake pipeline 154B disposed in the liner 121 are separate components, it is convenient to disassemble the steam valve assembly from the liner 121.

[0061] A first seal 192 is provided between the steam valve assembly and the liner 121 to prevent gas from entering the second intake pipeline 154B and ultimately entering the cavity space through the gap between the steam valve assembly and the liner 121 without passing through the steam filter at the steam outlet 182.

[0062] Specifically, the steam valve assembly includes a steam valve base 191. A steam valve 193 is provided on the steam valve base 191. The steam valve base 191 is detachably mounted to the liner 121. The first intake pipeline 154A is disposed in the steam valve base 191. The first seal 192 is provided between the steam valve base 191 and the liner 121. The first seal 192 can be a radial seal, which is convenient for assembly and has a good sealing effect.

[0063] More specifically, the cover 121 is provided with a cover protrusion 121A protruding upward (i.e., toward the steam valve base 191). The steam valve base 191 is provided with a recess 191A recessed upward (i.e., in a direction away from the cover 121), and the recess 191A can cooperate with the cover protrusion 121A. During assembly, the cover protrusion 121A is received in the recess 191A of the steam valve base 191. The first seal 192 is sleeved on the cover protrusion 121A so that the first seal 192 can be located between the cover protrusion 121A and the side wall of the recess 191A to achieve sealing between the cover 121 and the steam valve base 191, so as to prevent gas from entering the second suction pipe 154B in the cover 121 through the gap between the steam valve base 191 and the cover 121 without passing through the steam filter at the steam outlet 182 and finally entering the cavity space. The first seal 192 can be made of any suitable elastic material such as silica gel. Of course, the first seal 192 can also be an axial seal provided between the cover protrusion 121A and the bottom wall of the recess 191A.

[0064] In addition, the steam valve assembly further includes a steam valve upper cover 194. The steam valve upper cover 194 is detachably mounted above the steam valve base 191. At least a part of the steam passage 180 is formed between the steam valve upper cover 194 and the steam valve base 191. A steam valve decorative cover 122B is provided on the steam valve upper cover 194 to make the appearance of the cooking appliance 100 beautiful. A through hole communicating with the steam outlet 182 on the steam valve decorative cover 122B is provided on the steam valve upper cover 194. A second seal 195 is provided between the steam valve upper cover 194 and the steam valve base 191. The second seal 195 can also be a radial seal, which is convenient for assembly and has a good sealing effect.

[0065] Specifically, the steam valve upper cover 194 is provided with a mounting hole 194A. The steam valve base 191 is provided with a mounting portion 191B. The mounting portion 191B of the steam valve base 191 can pass through the mounting hole 194A of the steam valve upper cover 194. The second seal 195 is sleeved on the mounting portion 191B of the steam valve base 191 so that the second seal 195 is located between the steam valve upper cover 194 and the mounting portion 191B of the steam valve base 191. The second seal 195 can prevent steam from entering the first suction pipe 154A in the steam valve base 191 through the gap between the steam valve upper cover 194 and the steam valve base 191.

[0066] It should be noted that although in this embodiment, the intake pipe 154 is shown as including a first intake pipe 154A provided in the steam valve assembly and a second intake pipe 154B provided in the liner cover 121, the intake pipe 154 may also include only the first intake pipe 154A provided in the steam valve assembly, that is, the first end of the first intake pipe 154A communicates with the intake port 151, and the second end is connected to the gas delivery device.

[0067] In addition, it should be noted that although in this embodiment, the first intake pipe 154A provided in the steam valve base 191 and the second intake pipe 154B provided in the liner cover 121 are shown as separate components to facilitate the detachable installation of the steam valve base 191 to the liner cover 121, in other embodiments not shown in the present invention, the first intake pipe 154A and the second intake pipe 154B may also be an integral component. The intake pipe 154 is inserted into the steam valve assembly, and the steam valve assembly can be detached from the liner cover 121. In this case, since the first intake pipe 154A and the second intake pipe 154B are an integral component, the first seal 192 can be omitted between the steam valve assembly and the liner cover 121.

[0068] As Figure 5 and Figure 6 shown, the cover body 120 further includes a stop member 124. The stop member 124 covers the first end of the intake pipe 154, that is, the end communicating with the intake port 151, and forms an intake gap with the first end of the intake pipe 154. On the one hand, the stop member 124 can cover the first end of the intake pipe 154, preventing the first end of the intake pipe 154 from being exposed outside, so that other sundries (such as water, cockroaches, etc.) will not enter the intake pipe 154, avoiding blockage of the intake pipe 154 and not affecting the delivery of external gas to the cavity space during cooking. On the other hand, the intake gap formed between the stop member 124 and the first end of the intake pipe 154 enables the intake pipe 154 to communicate with the intake port 151, and external gas can enter the intake pipe 154 through the intake port 151.

[0069] The stopper member 124 includes a decorative cover located on the outer surface of the cover body 120 and covering the first end of the air suction pipe 154. Specifically, in an embodiment of the present invention, the stopper member 124 includes a steam valve decorative cover 122B located on the outer surface of the steam valve assembly. The steam valve decorative cover 122B covers the first end of the air suction pipe 154, that is, the end communicating with the air suction port 151. More specifically, the steam valve decorative cover 122B covers the first end of the first air suction pipe 154A, that is, the end communicating with the air suction port 151. That is, when the cover body 120 is in the closed position, when looking down from above the cover body 120 or the cooking appliance 100, the first end of the air suction pipe 154 is blocked by the steam valve decorative cover 122B and cannot be observed. It can be understood that the projection of the first end of the air suction pipe 154 on the decorative cover is spaced apart from the air suction port 151. Specifically, in an embodiment of the present invention, the projection of the first end of the air suction pipe 154 on the steam valve decorative cover 122B is spaced apart from the air suction port 151 on the steam valve decorative cover 122B. Since the steam valve decorative cover 122B covers the first end of the air suction pipe 154, it is possible to prevent the first end of the air suction pipe 154 from being directly exposed outside, and prevent other sundries (such as water, cockroaches, etc.) from entering the air suction pipe 154.

[0070] Furthermore, the stopper member 124 further includes a protrusion 124A protruding downward from the decorative cover (specifically, the steam valve decorative cover 122B). The protrusion 124A is located between the air suction port 151 and the first end of the air suction pipe 154. The protrusion 124A surrounds the first end of the air suction pipe 154. Thus, the portion of the steam valve decorative cover 122B located at the first end of the air suction pipe 154 and the protrusion 124A together form an inverted buckle cover covering the first end of the air suction pipe 154. Due to the presence of the protrusion 124A, the gas from the air suction port 151 cannot directly enter the air suction pipe 154, but is blocked by the protrusion 124A and enters the air suction pipe through a curved path. Due to the gravity, other sundries will not enter the air suction pipe 154 together with the outside gas, avoiding blockage of the air suction pipe 154.

[0071] It can be understood that the inner side wall of the protrusion 124A should be spaced apart from the outer side wall of the first end of the air suction pipe 154 so that the air suction port 151 can communicate with the air suction pipe 154. The applicant found that if the distance between the inner side wall of the protrusion 124A and the outer side wall of the first end of the air suction pipe 154 is too small, it is easy to affect the communication between the air suction port 151 and the air suction pipe 154 due to the adhesion of water. Therefore, optionally, the horizontal distance between the inner side wall of the protrusion 124A and the outer side wall of the first end of the air suction pipe 154 is greater than or equal to 1 mm to avoid the adhesion of water and ensure the communication between the air suction port 151 and the air suction pipe 154.

[0072] Optionally, the lowermost end of the protrusion 124A is lower than the first end of the intake pipe 154. This can ensure that other sundries do not enter the intake pipe 154 together with the external gas due to gravity and block the intake pipe 154.

[0073] Since the steam outlet 182 is arranged around the suction port 151, the steam from the steam outlet 182 can easily form a small amount of condensed water around the suction port 151. Optionally, the cover 120 may further include a waterproof member to prevent liquid from flowing into the suction port 151.

[0074] Specifically, in one embodiment of the present invention, the waterproof member is a boss located between the suction port 151 and the steam outlet 182. The boss is spaced apart from the steam outlet 182. A steam outlet surface is formed between the boss and the steam outlet 182. The steam outlet surface may be higher than the steam outlet 182, flush with the steam outlet surface, or lower than the steam outlet surface. The boss is higher than the steam outlet surface. Further optionally, the boss is higher than the steam outlet 182. In this way, the boss blocks between the steam outlet 182 and the suction port 151, and since the boss is higher than the steam outlet surface, the condensed water will gather between the steam outlet surfaces under the action of gravity and will not cross the boss and enter the suction port 151.

[0075] Optionally, in another embodiment of the present invention, the waterproof member is a boss 125 partially located between the suction port 151 and the steam outlet 182. The boss 125 is spaced apart from the steam outlet 182 and a steam outlet surface is formed between the boss 125 and the steam outlet 182. The boss 125 is higher than the steam outlet surface. The suction port 151 is arranged on the boss 125. Since the boss 125 is higher than the steam outlet surface, the condensed water will gather on the steam outlet surface under the action of gravity and will not enter the suction port 151 arranged on the boss 125.

[0076] In summary, when the cover according to the present invention is used for a cooking appliance, since the steam outlet is arranged around the suction port, the steam discharged through the steam outlet will form a circumferentially continuous or closed steam curtain around and above the suction port to filter the gas inhaled into the suction port, avoiding the inhalation of sundries such as oil fume and dust into the suction port, thereby avoiding the presence of oil stains or dirt in the gas pipeline or even blockage, and also avoiding affecting the taste of the food.
