Description

Technical Field

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

[0002] The rice cooker is equipped with a steam valve, which mainly serves the purpose of exhausting and breaking bubbles. The high-temperature steam generated by the rice cooker during cooking will be discharged from the inside of the rice cooker to the outside through the steam valve, and the bubbles formed by the steam will be broken during the discharge process, preventing the bubbles from sticking to the outer surface of the rice cooker due to their large volume bursting when passing through the exhaust port of the steam valve during the discharge process.

[0003] In the related art, steam valves are divided into external and internal types. Regardless of whether they are external or internal, the steam valve is a component independent of the cover body. When installing the steam valve, multiple sealing rings are usually required to achieve the seal between the steam valve and the surface cover and inner cover. The number of parts is large, the assembly process is complicated, and an independent mold for the steam valve needs to be prepared, resulting in a large number of molds and high costs. Utility Model Content

[0004] In view of this, the present invention provides a cover assembly and a cooking utensil to solve the problems in the related art that the cover assembly has a large number of parts and a complicated assembly process.

[0005] In a first aspect, the present invention provides a cover assembly, comprising:

[0006] inner cover;

[0007] The surface cover cooperates with the inner cover to form a steam channel. The surface cover is provided with a steam outlet communicated with the steam channel. At least part of the steam outlet is provided with a guide rib for discharging steam obliquely upward.

[0008] Beneficial Effects: Because the top cover and inner lid cooperate to form a steam passage, the steam valve is effectively integrated with the top cover or inner lid. Compared to related technologies, this reduces the number of steam valves, reduces the number of parts, and simplifies the assembly process. By providing guide ribs at the steam outlet, the ribs allow the steam to be discharged upward at an angle, preventing it from being discharged directly toward people. Furthermore, the ribs break up bubbles generated by the water vapor, preventing them from bursting after passing through the steam outlet and adhering to the outer surface of the rice cooker. When the steam passage needs to be cleaned, simply insert a rag into the passage and scrub it, making it easy for users to clean without removing the inner cover or top cover.

[0009] In an optional embodiment, the steam outlet includes a first outlet and a second outlet, and the guide rib is provided at the first outlet.

[0010] Beneficial effect: Since the guide rib is provided at the first outlet and no guide rib is provided at the second outlet, the steam discharged from the first outlet is discharged obliquely upward, and the steam discharged from the second outlet is discharged vertically upward.

[0011] In an optional embodiment, the guide rib is connected to the surface cover via a first connecting structure, and the first connecting structure divides the first outlet into at least two first outlet sections;

[0012] And / or, the middle of the second outlet is connected to the surface cover via a second connecting structure, and the second connecting structure divides the second outlet into at least two second outlet sections.

[0013] Beneficial effects: The provision of the first connection structure can enhance the strength of the surface cover at the first outlet; the provision of the second connection structure can enhance the strength of the surface cover at the second outlet.

[0014] In an optional embodiment, the two ends of the guide rib are respectively a first connecting end and a second connecting end, the first connecting end is connected to the first end of the first outlet, and the second connecting end is connected to the second end of the first outlet.

[0015] Beneficial effect: The first connecting end is connected to the first end of the first outlet, and the second connecting end is connected to the second end of the first outlet, which can increase the structural strength of the steam outlet of the cover while preventing shrinkage.

[0016] In an optional embodiment, the guide rib protrudes from the inner wall of the steam channel, and the protruding height is L, 0.1mm≤L≤2mm.

[0017] Beneficial effect: The protruding height of the guide rib is between 0.1mm and 2mm, which can effectively guide the flow and ensure the passage of steam.

[0018] In an optional embodiment, a boss is provided on the upper surface of the cover, and the steam outlet is provided on the boss.

[0019] Beneficial effect: By arranging a boss on the upper surface of the cover and arranging the steam outlet on the boss, the user can be reminded of the position of the steam outlet, thereby preventing the user from touching the steam outlet when using the cooking utensil.

[0020] In an optional embodiment, the height of the boss is h1, where h1<1 mm.

[0021] Beneficial effect: The height of the boss is less than 1 mm, which is not very high, and thus does not affect the overall aesthetics of the cover assembly.

[0022] In an optional embodiment, the surface cover has a first protrusion extending downward, and the first protrusion cooperates with the inner cover to form a steam channel.

[0023] Beneficial effects: the first protrusion cooperates with the inner cover to form a steam channel, and no additional steam valve is required. In addition, the first protrusion is easy to be injection molded, and the structure of the surface cover is simple and easy to process.

[0025] Beneficial effect: By setting the first annular groove, the first sealing part of the sealing structure is embedded in the first annular groove, that is, the sealing structure is located between the first protrusion and the inner cover and is embedded in the first annular groove, which can ensure the sealed connection between the surface cover and the inner cover, and prevent steam from entering the electrical components arranged between the surface cover and the inner cover through the gap between the first protrusion and the inner cover.

[0026] In an optional embodiment, the inner side of the first annular groove constitutes a second protrusion, and the inner cover further has a rib surrounding the outer side of the first annular groove, and the height of the rib is higher than the height of the second protrusion.

[0027] Beneficial effect: Since the height of the rib is higher than the height of the second protrusion and the rib surrounds the outside of the first annular groove, when the sealing performance of the sealing structure fails, it can play a role in blocking water and prevent water from entering the electrical components arranged between the surface cover and the inner cover.

[0028] In an optional embodiment, a guide structure is provided on the inner side of the rib.

[0029] Beneficial effect: By arranging the guide structure on the inner side of the rib, the sealing structure can be easily installed.

[0030] In an optional embodiment, the inner side of the second protrusion constitutes a mounting through hole, and the sealing structure further includes a main body sealing portion that is interference-fitted with the mounting through hole.

[0031] Beneficial effect: Since the main sealing part of the sealing structure is embedded in the inner side of the second protrusion, the sealing structure and the inner cover can be closely matched, further improving the sealing effect and preventing steam from entering the electrical components arranged between the surface cover and the inner cover.

[0032] In an optional embodiment, the first protrusion is provided with a second annular groove, and the sealing structure has a second sealing portion embedded in the second annular groove.

[0033] Beneficial effect: Since the second sealing part of the sealing structure is embedded in the second annular groove of the first protrusion, the sealed connection between the first protrusion and the second protrusion can be further ensured, preventing steam from entering the electrical components arranged between the surface cover and the inner cover through the gap between the first protrusion and the second protrusion.

[0034] In an optional embodiment, the sealing structure and the first protrusion are interference fit through a concave-convex structure.

[0035] Beneficial effect: Since the sealing structure and the first protrusion are interference fit through the concave-convex structure, the sealing between the sealing structure and the first protrusion can be ensured, preventing steam from entering the electrical components arranged between the surface cover and the inner cover through the gap between the first protrusion and the sealing structure.

[0036] In a second aspect, the present invention further provides a cooking utensil, comprising:

[0037] The cover assembly.

[0038] Beneficial Effects: Because the top cover and inner lid cooperate to form a steam channel, the steam valve is effectively integrated with the top cover or inner lid. Compared to related technologies, this reduces the number of steam valves, reduces the number of parts, and simplifies the assembly process. By providing guide ribs at the steam outlet, the ribs diagonally discharge steam upward, preventing it from being discharged directly toward people. Furthermore, the ribs break up bubbles generated by the steam, preventing them from bursting after passing through the steam outlet and adhering to the outer surface of the rice cooker.

[0055] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0056] The rice cooker is equipped with a steam valve, which mainly serves the purpose of exhausting and breaking bubbles. The high-temperature steam generated by the rice cooker during cooking will be discharged from the inside of the rice cooker to the outside through the steam valve, and the bubbles formed by the steam will be broken during the discharge process, preventing the bubbles from sticking to the outer surface of the rice cooker due to their large volume bursting when passing through the exhaust port of the steam valve during the discharge process.

[0057] In the related art, steam valves are divided into external and internal types. Regardless of whether they are external or internal, the steam valve is a component independent of the cover body. When installing the steam valve, multiple sealing rings are usually required to achieve the seal between the steam valve and the surface cover and inner cover. The number of parts is large, the assembly process is complicated, and an independent mold for the steam valve needs to be prepared, resulting in a large number of molds and high costs.

[0058] The following combination Figures 1 to 13 , describing the embodiments of the present utility model.

[0059] According to an embodiment of the present invention, on one hand, a cover assembly is provided, comprising a surface cover 2 and an inner cover 1 .

[0060] The surface cover 2 cooperates with the inner cover 1 to form a steam channel. The surface cover 2 is provided with a steam outlet connected to the steam channel. At least part of the steam outlet is provided with a guide rib 203 for discharging the steam obliquely upward.

[0061] In this embodiment, since the cover 2 cooperates with the inner cover 1 to form a steam passage, it is equivalent to forming a steam valve integrally with the cover 2 or the inner cover 1. Compared with the related art, the steam valve is reduced in number, the number of parts is reduced, and the assembly process is simplified. By providing a guide rib 203 at the steam outlet, the guide rib 203 can cause the steam to be discharged upward at an angle, preventing the steam from being discharged directly toward the user. At the same time, the guide rib 203 can break up the bubbles generated by the water vapor, preventing the bubbles from being too large and bursting after passing through the steam outlet and adhering to the outer surface of the rice cooker. When the steam passage needs to be cleaned, a rag can be inserted into the steam passage to clean it, which is convenient for the user to clean without having to disassemble the inner cover 1 and the cover 2.

[0062] In one embodiment, Figure 2 As shown, the steam outlet includes a first outlet 201 and a second outlet 202 , and the guide rib 203 is provided at the first outlet 201 .

[0063] In this embodiment, since the guide rib 203 is provided at the first outlet 201 and no guide rib 203 is provided at the second outlet 202, the steam discharged from the first outlet 201 is discharged obliquely upward, and the steam discharged from the second outlet 202 is discharged vertically upward.

[0064] In one embodiment, the guide rib 203 is connected to the cover 2 via a first connecting structure 210, which divides the first outlet 201 into at least two first outlet sections; and / or, the middle of the second outlet 202 is connected to the cover via a second connecting structure 211, which divides the second outlet 202 into at least two second outlet sections.

[0065] In this embodiment, the provision of the first connection structure 210 can enhance the strength of the surface cover 2 at the first outlet 201 ; the provision of the second connection structure 211 can enhance the strength of the surface cover 2 at the second outlet 202 .

[0066] Specifically in one embodiment, Figure 4 As shown, one first connection structure 210 is provided to separate the first outlet 201 into two first outlet sections; one second connection structure 211 is provided to separate the second outlet 202 into two second outlet sections.

[0067] In this embodiment, there is no limitation on the number of the first connection structure 210 and the second connection structure 211 , which can be one, two, or three.

[0068] In one embodiment, Figure 4 As shown, the two ends of the guide rib 203 are respectively a first connecting end 204 and a second connecting end 205 . The first connecting end 204 is connected to the first end of the first outlet 201 , and the second connecting end 205 is connected to the second end of the first outlet 201 .

[0069] In this embodiment, the first connecting end 204 is connected to the first end of the first outlet 201, and the second connecting end 205 is connected to the second end of the first outlet 201, which can increase the structural strength of the steam outlet of the cover 2 while preventing shrinkage.

[0070] In one embodiment, the guide rib 203 protrudes from the inner wall of the steam channel, and the protruding height is L, 0.1 mm≤L≤2 mm.

[0071] In this embodiment, the protruding height of the guide rib 203 is between 0.1 mm and 2 mm, which can effectively guide the flow and ensure the passage of steam.

[0072] Specifically in one embodiment, the protruding height of the guide rib 203 is 0.1 mm.

[0073] Specifically in one embodiment, the protruding height of the guide rib 203 is 1 mm.

[0074] Specifically in one embodiment, the protruding height of the guide rib 203 is 2 mm.

[0075] In one embodiment, Figure 1 As shown, a boss 206 is provided on the upper surface of the cover 2 , and a steam outlet is provided on the boss 206 .

[0076] In this embodiment, a boss 206 is provided on the upper surface of the cover 2 and a steam outlet is provided on the boss 206 , which can remind the user of the location of the steam outlet and prevent the user from touching the steam outlet when using the cooking appliance.

[0077] In one embodiment, the height of the boss 206 is h1, where h1 is less than 1 mm.

[0078] In this embodiment, the height of the boss 206 is less than 1 mm, which is not very high, and thus will not affect the overall aesthetics of the cover assembly.

[0079] Specifically in one embodiment, the height of the boss 206 is 0.5 mm.

[0080] Specifically in one embodiment, the height of the boss 206 is 0.8 mm.

[0081] Specifically in one embodiment, the height of the boss 206 is 0.3 mm.

[0082] In one embodiment, the surface cover 2 has a first protrusion 207 extending downward, and the first protrusion 207 cooperates with the inner cover 1 to form a steam channel.

[0083] In this embodiment, the first protrusion 207 cooperates with the inner cover 1 to form a steam channel, and no additional steam valve is required. In addition, the first protrusion 207 is easy to be injection molded, and the structure of the surface cover 2 is simple and easy to process.

[0084] Specifically in one embodiment, the first protrusion 207 is an annular protrusion, and the inner side of the first protrusion 207 is suitable for steam to pass through.

[0085] In one embodiment, a sealing structure 3 is provided between the first protrusion 207 and the inner cover 1 . The inner cover 1 has a first annular groove 101 . The sealing structure 3 has a first sealing portion 301 embedded in the first annular groove 101 .

[0086] In this embodiment, by providing the first annular groove 101, the first sealing portion 301 of the sealing structure 3 is embedded in the first annular groove 101, that is, the sealing structure 3 is located between the first protrusion 207 and the inner cover 1, and is embedded in the first annular groove 101, which can ensure the sealed connection between the surface cover 2 and the inner cover 1, and prevent steam from entering the electrical components arranged between the surface cover 2 and the inner cover 1 through the gap between the first protrusion 207 and the inner cover 1.

[0087] Specifically in one embodiment, the space between the surface cover 2 and the inner cover 1 is provided with electrical components such as a top temperature sensing device and a display assembly.

[0088] In one embodiment, the inner side of the first annular groove 101 forms a second protrusion 102 , and the inner cover 1 further has a rib 103 surrounding the outer side of the first annular groove 101 , and the height of the rib 103 is higher than the height of the second protrusion 102 .

[0089] In this embodiment, since the height of the rib 103 is higher than the height of the second protrusion 102, and the rib 103 surrounds the outside of the first annular groove 101, when the sealing performance of the sealing structure 3 fails, it can play a role in blocking water and prevent water from entering the electrical components arranged between the surface cover 2 and the inner cover 1.

[0090] In one embodiment, a guide structure 1031 is provided on the inner side of the rib 103 .

[0091] In this embodiment, by providing a guide structure 1031 on the inner side of the rib 103 , the sealing structure 3 can be easily installed.

[0092] Specifically in one embodiment, when assembling the cover body assembly, the sealing structure 3 is installed on the inner cover 1 from top to bottom on the inner side of the rib 103, and the first sealing portion 301 of the sealing structure 3 is embedded in the first annular groove 101 of the inner cover 1. Then, the surface cover 2 is assembled onto the inner cover 1, so that the first protrusion 207 of the surface cover 2 is opposite to the second protrusion 102 of the inner cover 1, so that the first protrusion 207 presses the sealing ring, and then the surface cover 2 and the inner cover 1 are fixed by snaps and screws.

[0093] Specifically in one embodiment, the guide structure 1031 is a guide slope provided on the inner side of the top of the rib 103 .

[0094] In one embodiment, the inner side of the second protruding portion 102 constitutes a mounting through hole, and the sealing structure 3 further includes a main body sealing portion that is interference-fitted with the mounting through hole.

[0095] In this embodiment, since the main sealing portion of the sealing structure 3 is embedded in the inner side of the second protrusion 102, the sealing structure 3 can be tightly matched with the inner cover 1, further improving the sealing effect and preventing steam from entering the electrical components arranged between the surface cover 2 and the inner cover 1.

[0096] In one embodiment, the cover assembly also includes an insulation cover plate 4, which is detachably connected to the inner cover 1. The insulation cover plate 4 is provided with a steam inlet 401. The sealing structure 3 also includes an abutting sealing portion 303 extending out of the mounting through hole, and the abutting sealing portion 303 abuts against the insulation cover plate 4.

[0097] In this embodiment, since the heat-insulating cover plate 4 is detachably connected to the inner cover 1, when the steam passage needs to be cleaned, the heat-insulating cover plate 4 is removed from the inner cover 1 and a rag is then inserted into the steam passage to clean it. This facilitates cleaning and eliminates the need to remove the inner cover 1 and the top cover 2. Furthermore, since the abutting seal 303 abuts the heat-insulating cover plate 4, a sealing effect is ensured, preventing steam or rice water from cooking from coming into contact with the inner cover 1, thus reducing the number of areas that the user needs to clean.

[0098] Specifically in one embodiment, Figures 5 to 7 As shown, the steam inlet 401 includes a plurality of arc-shaped holes arranged at intervals.

[0099] In one embodiment, Figure 9 As shown, from top to bottom, the abutting sealing portion 303 extends toward the axial direction close to the steam channel.

[0100] In this embodiment, since the abutting sealing portion 303 extends from top to bottom toward the axial direction close to the steam channel, the abutting sealing portion 303 is easily deformed when abutting against the thermal insulation cover 4, ensuring the sealing effect, preventing steam or rice soup during cooking from contacting the inner cover 1, and reducing the areas that the user needs to clean.

[0101] In one embodiment, Figure 12 and Figure 13 As shown, the abutting sealing portion 303 includes an outward expansion section 3031 and a contraction section 3032. From top to bottom, the outward expansion section 3031 extends toward the axial direction away from the steam channel, and the contraction section 3032 extends toward the axial direction close to the steam channel. The contraction section 3032 abuts against the thermal insulation cover plate 4.

[0102] In this embodiment, the provision of the outward expansion section 3031 and the contraction section 3032 can make the abutting sealing portion 303 more likely to deform, thereby further ensuring the sealing contact between the sealing structure 3 and the thermal insulation cover plate 4.

[0103] Specifically in one embodiment, Figure 13 As shown, a step portion 3033 is provided on the outer side of the outward expansion section 3031, and the horizontal surface of the step portion 3033 abuts against the lower surface of the inner cover 1. The step portion 3033 can limit the outward expansion section 3031 to ensure that the abutting sealing portion 303 can contact the thermal insulation cover plate 4.

[0104] Specifically in one embodiment, Figure 13As shown, the contraction section 3032 is provided with an annular rib 3034 , which can increase the strength of the abutment sealing portion 303 .

[0105] In one embodiment, Figures 8 to 11 As shown, the first protrusion 207 is provided with a second annular groove 208 , and the sealing structure 3 has a second sealing portion 302 embedded in the second annular groove 208 .

[0106] In this embodiment, since the second sealing portion 302 of the sealing structure 3 is embedded in the second annular groove 208 of the first protrusion 207, the sealed connection between the first protrusion 207 and the second protrusion 102 can be further ensured, preventing steam from entering the electrical components arranged between the surface cover 2 and the inner cover 1 through the gap between the first protrusion 207 and the second protrusion 102.

[0107] Specifically in one embodiment, Figure 8 and Figure 9 As shown, the sealing structure 3 is located between the first protrusion 207 and the second protrusion 102, and the first sealing portion 301 of the sealing structure 3 is embedded in the first annular groove 101 of the inner cover 1, and the second sealing portion 302 of the sealing structure 3 is embedded in the second annular groove 208 of the first protrusion 207, which can achieve all-round sealing and ensure the sealing effect.

[0108] Specifically in one embodiment, Figure 12 and Figure 13 As shown, the sealing structure 3 is located between the first protruding portion 207 and the second protruding portion 102 , and the first sealing portion 301 of the sealing structure 3 is embedded in the first annular groove 101 of the inner cover 1 .

[0109] In one embodiment, the sealing structure 3 and the first protrusion 207 are interference-fitted through a concave-convex structure.

[0110] In this embodiment, since the sealing structure 3 and the first protrusion 207 are interference fit through the concave-convex structure, the sealing between the sealing structure 3 and the first protrusion 207 can be ensured, preventing steam from entering the electrical components arranged between the surface cover 2 and the inner cover 1 through the gap between the first protrusion 207 and the sealing structure 3.

[0111] Specifically in one embodiment, Figure 13 As shown, two annular protrusions 209 are provided on one side of the first protrusion 207 facing the sealing structure 3 . The position where the first protrusion 207 abuts against the sealing structure 3 is more easily deformed, thereby ensuring the sealing effect.

[0112] According to an embodiment of the present invention, on the other hand, a cooking utensil is provided, comprising: the cover assembly provided in the above embodiment.

[0113] In this embodiment, since the top cover 2 and the inner cover 1 cooperate to form a steam passage, the steam valve is effectively integrated with the top cover 2 or the inner cover 1. Compared to related art, this reduces the number of steam valves, reduces the number of parts, and simplifies the assembly process. By providing guide ribs 203 at the steam outlet, the guide ribs 203 cause the steam to be discharged upward at an angle, preventing it from being discharged directly toward a person. Furthermore, the guide ribs 203 break up bubbles generated by the water vapor, preventing them from rupturing after passing through the steam outlet and adhering to the outer surface of the rice cooker due to their large volume.

[0114] Specifically in one embodiment, the cooking appliance is an electric rice cooker or a pressure cooker.

[0115] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by this application.
