The air inlet device 100 of the cooking appliance 200 and the cooking appliance 200 according to the embodiment of the present invention are described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a cooking appliance 200 according to an embodiment of the present invention may include an air inlet device 100 of the cooking appliance 200 according to an embodiment of the present invention. As shown in fig. 2 to 4, the air inlet device 100 of the cooking appliance 200 according to the embodiment of the present invention may include an air inlet valve 10 and a blocking member 20.

Specifically, as shown in fig. 2 and 4, the cooking appliance 200 may have a cooking cavity 201, and the cooking cavity 201 is used for containing food materials to cook the food materials. For example, rice grains and water may be put into the cooking cavity 201 to steam rice, and of course, the cooking appliance 200 may be used not only to steam rice, but also to cook porridge, soup, stew pork ribs, and the like. Air inlet unit 100 is used for letting in steam to cooking chamber 201 in to the edible material to cooking chamber 201 in carries out steam cooking, and hot steam is more abundant with the edible material contact, is favorable to improving the homogeneity that the edible material is heated.

As shown in fig. 2 to 4, the intake valve 10 has an intake passage 11, and at least a portion of the intake valve 10 protrudes into the cooking chamber 201 so that the steam outlet 111 of the intake passage 11 can be located in the cooking chamber 201 to communicate with the cooking chamber 201. Steam can be directly introduced into the cooking cavity 201 through the air inlet channel 11, and compared with the technical scheme that steam enters the cooking cavity from the top opening in the related art, the air inlet valve 10 disclosed by the utility model can enable the steam to be more fully contacted with food materials in the cooking cavity 201, so that the food materials in all areas are heated more uniformly, and the uniformity and the taste of food material cooking are improved.

In some embodiments, the air inlet device 100 may be disposed at a lower portion of the cooking cavity 201, for example, may be disposed at a lower portion of a bottom wall or a sidewall of the cooking cavity 201. From this, steam outlet 111 can communicate with the lower part of culinary art chamber 201, and the steam of output can be at once with eating the material direct contact, especially can with the edible material direct contact of culinary art chamber 201 lower part, and heat transfer efficiency is higher, and the culinary art speed is faster, and is favorable to further improving the homogeneity of eating the material culinary art, can effectively improve the problem that the lower part is eaten the material taste and is poor among the correlation technique.

Because the volume of the air inlet valve 10 is small, at least one part of the air inlet valve 10 occupies a small space when extending into the cooking cavity 201, the space of the cooking cavity 201 is not influenced, the interference to food materials is very small and can be ignored, the placing and cooking of any food materials are not influenced, the cooking appliance 200 can be used for cooking small-volume food materials such as porridge and rice, can be used for cooking large-block food materials such as spareribs and meat blocks, and the normal use of the cooking appliance 200 is ensured.

Further, as shown in fig. 3 and 4, the intake apparatus 100 further includes a blocking piece 20, and the blocking piece 20 is provided to the intake valve 10. The block piece 20 always blocks the intake passage 11, and the block piece 20 can conduct the intake passage 11 by the steam pressure. Therefore, when steam needs to be introduced into the cooking cavity 201, the steam pressure drives the plugging piece 20 to move so as to conduct the air inlet channel 11, so that the steam smoothly enters the cooking cavity 201 to be in contact with food materials, a component for driving the plugging piece 20 to move does not need to be additionally arranged, and the air inlet device 100 is simpler. Moreover, as the steam flows out from the steam outlet 111, under the action of the steam pressure, even if the air inlet valve 10 contacts with the food material, the food material can be prevented from entering the air inlet channel 11 to cause the blockage or the pollution of the air inlet channel 11, the cooking utensil 200 is more convenient to clean, and sanitary dead corners do not exist. When the steam is not required to be introduced into the cooking cavity 201, the blocking member 20 always blocks the air inlet channel 11, that is, the blocking member 20 is always in a position or state of blocking the air inlet channel 11, so as to prevent the food material from entering the air inlet channel 11.

In some related art, the steam outlet is not provided with a blocking piece, and the air inlet valve is required to be spaced apart from the food material when extending into the cooking cavity so as to avoid the air inlet valve being blocked by the food material. For example, the steam outlet is positioned at the lower part of the cooking cavity, and the food is placed on the steaming rack at the upper part of the cooking cavity; or the steam outlet is positioned at the upper part of the cooking cavity, and the food materials are placed at the lower part of the cooking cavity; or the steam guide pipe extends into the cooking cavity from top to bottom, and the steam outlet is arranged at the lower part of the steam guide pipe. These technical scheme exist the space utilization in culinary art chamber and hang down the thermal efficiency, and steam pipe interferes with the food material and leads to closing the inconvenient problem that can't close the lid even of lid.

By arranging the blocking piece 20, the air inlet device 100 is in a one-way conduction structure, the air inlet channel 11 is effectively prevented from being blocked by food materials in the food material boiling or storage process, the problem that sanitary dead corners exist due to the fact that the interior of the air inlet channel 11 is polluted is solved, meanwhile, the food materials in the cooking cavity 201 can be directly contacted with the air inlet device 100, the adding amount of the food materials is not limited by the installation position of the air inlet device 100, the space in the cooking cavity 201 can be fully utilized, cooking efficiency is improved, a steam guide pipe with a large volume is not needed to be arranged, interference with the food materials is avoided, the cooking appliance 200 can be smoothly covered, large food materials can be cooked, and the use is more convenient.

According to some embodiments of the present invention, as shown in fig. 3 and 4, at least a portion of the block piece 20 may be elastically deformed by the steam pressure to conduct the intake passage 11. For example, at least a part of the sealing member 20 may be a flexible member that is easily deformed, such as a rubber member or a silicone member, and the flexible member is deformed to elastically deform the sealing member 20 when the sealing member is subjected to steam pressure, so as to open the air inlet channel 11, and when the steam pressure is removed or is not low enough to deform the sealing member 20, the sealing member can be deformed to return to a state of blocking the air inlet channel 11. The state of the air inlet device 100 is sensitively switched along with the on-off of the steam, and the effect of preventing the air inlet channel 11 from being blocked or polluted is good.

In a specific embodiment, the whole plugging member 20 is a silica gel member, which is not only beneficial to improving the fixing reliability of the plugging member 20, but also beneficial to improving the sealing effect and the service life of the plugging member 20.

In addition, in some embodiments, as shown in fig. 4, the blocking piece 20 is disposed in the air inlet channel 11, so that the air inlet valve 10 can block and protect the blocking piece 20, so as to prevent the blocking piece 20 from being damaged by the food material, prevent the food material from directly contacting with the blocking piece 20 to affect the normal deformation of the blocking piece 20 and conducting the air inlet channel 11, and prevent the blocking piece 20 from being extruded and deviated by the food material to cause the failure of normally blocking the air inlet channel 11, thereby improving the service life of the blocking piece 20 and the reliability of operation.

The inlet valve 10 protects the closing member 20, and a protective structure such as a protective cover may be omitted. Of course, in order to further enhance the protection effect, in some embodiments of the present invention, the air intake device 100 may also include a protective cover, which is covered on the air intake valve 10, and has a cover chamber and a communication hole, which can communicate the cover chamber and the cooking chamber 201, and which can shield the steam outlet 111 of the air intake passage 11, so as to further enhance the effect of preventing the air intake passage 11 from being blocked and the effect of protecting the blocking piece 20. And the protective cover enables the appearance of the air inlet device 100 to be uniform and beautiful.

And, the aperture of the last intercommunicating pore of protection casing is less, can the great edible material of prefiltration volume, plays the preliminary guard effect that prevents air inlet unit 100 and be blockked up, improves air inlet unit 100's anti sediment effect. For example, in some embodiments, the aperture of the communication hole on the protective cover is less than or equal to 2mm, so that steam can rapidly burst out to cook food, solid substances such as food residues, rice grains and the like can be effectively prevented from contacting the blocking piece 20, and the risk that the blocking piece 20 is scratched and the air inlet channel 11 is opened by the solid substances is reduced.

In an embodiment of the present invention, the shield may be connected to the wall of the cooking chamber 201 or to the air intake valve 10. For example, the outer peripheral surface of admission valve 10 can be equipped with outer convex part, and the inner peripheral surface of protection casing is equipped with interior convex part, and outer convex part can move to the cover intracavity and be located one side that is close to the diapire of cover chamber of convex part to realize the joint of outer convex part and interior convex part, protection casing easy dismounting is convenient for manual dismouting washing the soup that condenses, and cleanability is high.

Specific structures of the intake valve 10 and the blocking member 20 according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

In some embodiments of the present invention, as shown in fig. 3 and 4, the intake valve 10 may include a valve body 12 and a valve cover 13. Wherein the valve body 12 defines a first passage 112, the valve cover 13 defines a second passage 113, the first passage 112 and the second passage 113 together constitute the intake passage 11, in other words, an outlet of the first passage 112 communicates with an inlet of the second passage 113, and an outlet of the second passage 113 is formed as the steam outlet 111.

In addition, the valve cover 13 is detachably coupled (e.g., threadedly coupled) to the valve body 12 to facilitate thorough cleaning of the interior of the air intake apparatus 100. And in embodiments where the closure 20 is provided inside the air inlet passage 11, the removable structure also facilitates installation, cleaning and replacement of the closure 20. For example, in some embodiments, as shown in fig. 4, the blocking member 20 may be provided in one of the first passage 112 and the second passage 113, and the blocking member 20 may block the passage opening of the other of the first passage 112 and the second passage 113 to block the intake passage 11, and the edge of the passage opening is formed as a sealing surface that is in sealing contact with the blocking member 20, without providing a sealing surface structure, and the structure of the intake valve 10 is simpler.

The specific connection structure of the blocking piece 20 and the intake valve 10 can be flexibly set according to actual conditions. In some embodiments of the present invention, as shown in fig. 3 and 4, the inner wall of the air intake channel 11 may be provided with a mounting post 133, and the blocking member 20 may be sleeved on the mounting post 133 to realize a post hole connection. In some embodiments, the mounting post 133 and the block piece 20 may be an interference fit to prevent the block piece 20 from falling off the mounting post 133; in some embodiments, the end (e.g., the lower end shown in fig. 4) of the mounting post 133 may be provided with a retaining protrusion 134, and the outer diameter of the retaining protrusion 134 is larger than the inner diameter of the blocking member 20, so as to prevent the blocking member 20 from being removed from the mounting post 133, and the connection between the intake valve 10 and the blocking member 20 is more reliable.

In some embodiments, as shown in fig. 4, the valve cover 13 defines a cover cavity 132, the cover cavity 132 is formed as part of the second passage 113, and an end wall of the cover cavity 132 may be provided with a mounting post 133 for mounting the block piece 20 to mount the block piece 20 in the intake passage 11.

In some embodiments, as shown in fig. 4, the sidewall of the cover cavity 132 may be provided with a plurality of air outlet passages 135, the cover cavity 132 and the air outlet passages 135 together constitute the second passage 113, the cover cavity 132 may communicate with the first passage 112, and an outlet of the air outlet passages 135 is formed as the steam outlet 111. Wherein, the flow area of outlet channel 135 is less than the flow area of lid chamber 132 to make the opening size of steam outlet 111 less, form preliminary protection, block that the edible material gets into inlet channel 11 inside, make air inlet unit 100 easily wash, also block edible material contact shutoff piece 20, reduce the damage and the pollution of shutoff piece 20.

According to some embodiments of the present invention, as shown in fig. 3 and 4, the block piece 20 may include: a connecting portion 21 and an annular deformation portion 22. Wherein the connecting portion 21 is connected to the intake valve 10, for example, the connecting portion 21 is connected to the mounting post 133 to connect the connecting portion 21 to the valve cover 13, thereby connecting the blocking piece 20 to the intake valve 10.

Further, as shown with continued reference to fig. 4, the inner circumferential edge of the annular deformation portion 22 may be connected to the connection portion 21, and the outer circumferential edge of the annular deformation portion 22 may be in sealing contact with the outlet edge of the first passage 112 to block the intake passage 11. Under the action of the steam pressure, the annular deformation portion 22 may be elastically deformed, so that the outer periphery of the annular deformation portion 22 may move in a direction away from the first passage 112 (e.g., upward as shown in fig. 4) to conduct the intake passage 11. When the steam pressure is removed or is not low enough to deform the plugging member 20, the annular deformation part 22 can restore the deformation, and the outer peripheral edge of the annular deformation part 22 is in sealing contact with the outlet edge of the first channel 112 again to block the air inlet channel 11. The annular deformation portion 22 is used for conducting and blocking the inside of the air inlet passage 11, and when the air inlet passage 11 is conducted, the flow area formed by the annular deformation portion 22 is larger, so that the improvement of air inlet efficiency and cooking efficiency are facilitated.

In some embodiments of the present invention, as shown in fig. 4, the annular deformation portion 22 may extend obliquely outward and toward the valve body 12, for example, in a direction away from the connection portion 21 and downward as shown in fig. 4, so that the annular deformation portion 22 is formed in a substantially umbrella shape. Thus, when the annular deformation portion 22 is in sealing contact with the outlet edge of the first channel 112, i.e. when the annular deformation portion 22 blocks the channel opening of the first channel 112, the annular deformation portion 22 may be deformed to some extent to increase the pressing force between the annular deformation portion 22 and the outlet edge of the first channel 112, thereby increasing the sealing effect.

In some embodiments, as shown in fig. 4, the thickness (e.g., the dimension in the vertical direction in fig. 4) of at least a portion of the annular deformation portion 22 may increase outward, so that the thinner portion of the annular deformation portion 22 is more easily elastically deformed by the steam pressure, and the communication of the air intake channel 11 is more sensitive.

In some embodiments of the present invention, as shown in fig. 4, the wall of the cooking chamber 201 is provided with a mounting hole 207, and the valve body 12 may include a valve seat 122 and a fixing member 124. The valve seat 122 has a first channel 112, the valve seat 122 is disposed through the mounting hole 207, the outer peripheral surface of the valve seat 122 is further provided with a positioning protrusion 123, the positioning protrusion 123 is located outside the cooking cavity 201, and the fixing member 124 is located inside the cooking cavity 201. The fixing member 124 may be coupled to the valve seat 122 to sandwich the edge of the mounting hole 207 between the fixing member 124 and the positioning protrusion 123. Thus, the valve body 12 is fixed, and when the bonnet 13 is separated from the valve body 12, the valve body 12 can be stably fixed to the wall of the cooking cavity 201 without displacement, and water leakage from the mounting hole 207 can be prevented.

In some embodiments, as shown in fig. 2 and 4, the cooking appliance 200 comprises a first cooking container 220, the first cooking container 220 comprising an outer pot 203 and an inner pot 202, the inner pot 202 being disposed within a pot cavity of the outer pot 203 and the inner pot 202 defining a cooking cavity 201. A portion of the valve seat 122 is positioned between the inner pot 202 and the outer pot 203, and another portion of the valve seat 122 passes through the mounting hole 207 and extends into the cooking chamber 201. The valve seat 122 can be clamped with the outer pot 203 or connected by a fastener or the like, or pressed and fixed by the inner pot 202 and the outer pot 203.

In some embodiments, as shown in fig. 4, the valve seat 122 may be connected with the fixing member 124 through a screw thread, specifically, a portion of the valve seat 122 extending into the cooking cavity 201 may be provided with an external screw thread, the fixing member 124 may be sleeved on the valve seat 122, and the fixing member 124 has an internal screw thread matching with the external screw thread of the valve seat 122. The connection mode is simple, and the assembly is easy.

In addition, as shown with continued reference to FIG. 4, the valve cover 13 also has internal threads that mate with the external threads of the valve seat 122. In other words, the same structure on the valve seat 122 for cooperating with the valve cover 13 and the fixing member 124 simplifies the structure of the valve seat 122. After the valve seat 122 is fixed on the wall of the cooking cavity 201 by the fixing member 124, the valve cover 13 is covered on the valve seat 122 and connected with the valve seat 122, and the assembly and disassembly of the valve cover 13 have no interference with the fixing member 124.

In some embodiments, as shown in fig. 4, the thickness of the fixing member 124 is smaller than the thickness of the valve cover 13 in the axial direction (e.g., the up-down direction shown in fig. 4) of the outlet of the first passage 112. The thickness of valve gap 13 is great on the one hand, and the operation is more convenient laborsaving during dismouting valve gap 13, does benefit to and carries out manual dismouting, and on the other hand mounting 124's thickness is less, can prevent that user's maloperation from pulling down mounting 124 and influencing valve body 12 fixed, and the structure is more reliable.
