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] The inner cover is provided with a first annular groove;

[0007] The cover has a first protrusion extending downward, wherein the first protrusion is provided with a second annular groove;

[0008] a sealing structure, disposed between the inner cover and the first protruding portion, and comprising a first sealing portion embedded in the first annular groove and a second sealing portion embedded in the second annular groove;

[0009] The sealing structure, the first protrusion and the inner cover form a steam channel, and the surface cover is provided with a steam outlet communicated with the steam channel.

[0010] Beneficial Effects: Because the front cover has a first protrusion extending downward, the sealing structure, the first protrusion, and the inner cover form a steam passage, which is equivalent to integrally forming the steam valve with the front cover or inner cover. Compared with related technologies, the number of steam valves is reduced, the number of parts is reduced, and the assembly process is simplified. Because the sealing structure is disposed between the inner cover and the first protrusion, and the first sealing portion of the sealing structure is embedded in the first annular groove of the inner cover, and the second sealing portion of the sealing structure is embedded in the second annular groove of the first protrusion, the front cover and the inner cover are sealed, preventing steam from entering the electrical components disposed between the front cover and the inner cover through the gap between the first protrusion and the inner cover.

[0011] 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.

[0012] 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.

[0013] In an optional embodiment, a guide structure is provided on the inner side of the rib.

[0014] Beneficial effect: By arranging the guide structure on the inner side of the rib, the sealing structure can be easily installed.

[0015] 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.

[0016] 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.

[0017] In an optional embodiment, the cover assembly further includes a heat-insulating cover plate, which is detachably connected to the inner cover, and the heat-insulating cover plate is provided with a steam inlet connected to the steam channel.

[0018] Beneficial effect: Since the thermal insulation cover and the inner cover are detachably connected, when the steam channel needs to be cleaned, the thermal insulation cover is removed from the inner cover, and then a rag is inserted into the steam channel to clean it, which is convenient for users to clean without removing the inner cover and the surface cover.

[0019] In an optional embodiment, the sealing structure further includes an abutting sealing portion extending out of the mounting through hole, and the abutting sealing portion abuts against the thermal insulation cover plate.

[0020] Beneficial effect: Since the abutting sealing portion abuts against the heat-insulating cover plate, the sealing effect can be ensured, preventing steam or rice soup during cooking from contacting the inner cover, and reducing the parts that the user needs to clean.

[0021] In an optional embodiment, from top to bottom, the abutting sealing portion extends toward an axial direction close to the steam channel.

[0022] Beneficial effect: Since the abutting sealing part extends from top to bottom toward the axial direction close to the steam channel, the abutting sealing part is easy to deform when abutting against the thermal insulation cover, ensuring the sealing effect, preventing steam or rice soup during cooking from contacting the inner cover, and reducing the parts that users need to clean.

[0023] In an optional embodiment, the abutting sealing portion includes an outward expansion section and a contraction section. From top to bottom, the outward expansion section extends in an axial direction away from the steam channel, and the contraction section extends in an axial direction close to the steam channel, and the contraction section abuts against the thermal insulation cover plate.

[0024] Beneficial effect: The provision of the outward expansion section and the contraction section can make the abutting sealing portion more easily deformed, thereby further ensuring the sealing contact between the sealing structure and the thermal insulation cover plate.

[0025] In an optional embodiment, a boss is provided on the upper surface of the cover, and the steam outlet is provided on the boss.

[0026] 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.

[0027] In a second aspect, the present invention further provides a cooking utensil, comprising:

[0028] The cover assembly.

[0029] Beneficial Effects: Because the front cover has a first protrusion extending downward, the sealing structure, the first protrusion, and the inner cover form a steam passage, which is equivalent to integrally forming the steam valve with the front cover or inner cover. Compared with related technologies, the number of steam valves is reduced, the number of parts is reduced, and the assembly process is simplified. Because the sealing structure is disposed between the inner cover and the first protrusion, and the first sealing portion of the sealing structure is embedded in the first annular groove of the inner cover, and the second sealing portion of the sealing structure is embedded in the second annular groove of the first protrusion, the front cover and the inner cover are sealed, preventing steam from entering the electrical components disposed between the front cover and the inner cover through the gap between the first protrusion and the inner cover.

DETAILED DESCRIPTION

[0046] 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.

[0047] 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.

[0048] 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.

[0049] The following combination Figures 1 to 13 , describing the embodiments of the present utility model.

[0050] According to an embodiment of the present invention, on one hand, a cover assembly is provided, including an inner cover 1 , a surface cover 2 and a sealing structure 3 .

[0051] Among them, the inner cover 1 is provided with a first annular groove 101; the surface cover 2 has a first protrusion 207 extending downward, and the first protrusion 207 is provided with a second annular groove 208; the sealing structure 3 is arranged between the inner cover 1 and the first protrusion 207, and has a first sealing portion 301 embedded in the first annular groove 101 and a second sealing portion 302 embedded in the second annular groove 208; the sealing structure 3, the first protrusion 207 and the inner cover 1 form a steam channel, and the surface cover 2 is provided with a steam outlet connected to the steam channel.

[0052] In this embodiment, since the front cover 2 has a first protrusion 207 extending downward, the sealing structure 3, the first protrusion 207, and the inner cover 1 form a steam passage, which is equivalent to integrally forming the steam valve with the front cover 2 or the inner cover 1. Compared with the related art, the steam valve is reduced, the number of parts is reduced, and the assembly process is simplified. Since the sealing structure 3 is arranged between the inner cover 1 and the first protrusion 207, 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, the front cover 2 and the inner cover 1 are sealed, preventing steam from entering the electrical components arranged between the front cover 2 and the inner cover 1 through the gap between the first protrusion 207 and the inner cover 1.

[0053] 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.

[0054] 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 .

[0055] 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.

[0056] In one embodiment, a guide structure 1031 is provided on the inner side of the rib 103 .

[0057] 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.

[0058] 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.

[0059] Specifically in one embodiment, the guide structure 1031 is a guide slope provided on the inner side of the top of the rib 103 .

[0060] 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.

[0061] 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.

[0062] In one embodiment, the cover assembly further includes a heat-insulating cover plate 4, which is detachably connected to the inner cover 1, and the heat-insulating cover plate 4 is provided with a steam inlet 401 connected to the steam channel.

[0063] In this embodiment, since the thermal insulation cover 4 is detachably connected to the inner cover 1, when the steam channel needs to be cleaned, the thermal insulation cover 4 is removed from the inner cover 1, and then a rag is inserted into the steam channel to wipe it, which is convenient for users to clean without removing the inner cover 1 and the surface cover 2.

[0064] Specifically in one embodiment, Figures 5 to 7 As shown, the steam inlet 401 includes a plurality of arc-shaped holes arranged at intervals.

[0065] In one embodiment, the sealing structure 3 further includes an abutting sealing portion 303 extending out of the mounting through hole, and the abutting sealing portion 303 abuts against the thermal insulation cover plate 4 .

[0066] In this embodiment, since the abutting sealing portion 303 abuts against the heat-insulating cover plate 4, a sealing effect can be ensured to prevent steam or rice soup during cooking from contacting the inner cover 1, thereby reducing the parts that the user needs to clean.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] Specifically in one embodiment, Figure 13 As shown, the contraction section 3032 is provided with an annular rib 3034 , which can increase the strength of the abutment sealing portion 303 .

[0073] 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.

[0074] 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 .

[0075] In one embodiment, the sealing structure 3 and the first protrusion 207 are interference-fitted through a concave-convex structure.

[0076] 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.

[0077] 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.

[0078] 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 .

[0079] 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.

[0080] In one embodiment, the height of the boss 206 is h1, where h1 is less than 1 mm.

[0081] 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.

[0082] Specifically in one embodiment, the height of the boss 206 is 0.5 mm.

[0083] Specifically in one embodiment, the height of the boss 206 is 0.8 mm.

[0084] Specifically in one embodiment, the height of the boss 206 is 0.3 mm.

[0085] In one embodiment, at least part of the steam outlet is provided with guide ribs 203 for discharging the steam obliquely upward.

[0086] In this embodiment, by arranging the guide rib 203 at the steam outlet, the guide rib 203 can make the steam be discharged upward at an angle to prevent the steam from being discharged directly towards people. At the same time, the guide rib 203 can break up the bubbles generated by the water vapor to prevent the bubbles from bursting after passing through the steam outlet due to their large volume and adhering to the outer surface of the rice cooker.

[0087] 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 .

[0088] 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.

[0089] In one embodiment, two first outlets 201 are symmetrically provided at intervals; and / or two second outlets 202 are symmetrically provided at intervals.

[0090] In this embodiment, by providing two first outlets 201 at intervals and symmetrically, the strength of the steam outlet cover 2 can be ensured while ensuring that the first outlet 201 has a sufficient area. By providing two second outlets 202 at intervals and symmetrically, the strength of the steam outlet cover 2 can be ensured while ensuring that the second outlet 202 has a sufficient area.

[0091] 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 end of one of the first outlets 201 close to the second outlet 202, and the second connecting end 205 is connected to the end of the other first outlet 201 close to the second outlet 202.

[0092] In this embodiment, the first connecting end 204 is connected to the end of one of the first outlets 201 close to the second outlet 202, and the second connecting end 205 is connected to the end of the other first outlet 201 close to the second outlet 202, which can increase the structural strength of the steam outlet of the cover 2 while preventing shrinkage.

[0093] In one embodiment, the length of the guide rib 203 in the direction of protruding from the inner wall of the steam channel is L, and 0.1 mm≤L≤2 mm.

[0094] In this embodiment, the length of the guide rib 203 in the direction of protruding from the inner wall of the steam channel is between 0.1 mm and 2 mm, which can effectively play a guiding role and ensure the passage of steam.

[0095] Specifically in one embodiment, the length of the guide rib 203 in the direction of protruding from the inner wall of the steam channel is 0.1 mm.

[0096] Specifically in one embodiment, the length of the guide rib 203 in the direction of protruding from the inner wall of the steam channel is 1 mm.

[0097] Specifically in one embodiment, the length of the guide rib 203 in the direction of protruding from the inner wall of the steam channel is 2 mm.

[0098] 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.

[0099] In this embodiment, since the front cover 2 has a first protrusion 207 extending downward, the sealing structure 3, the first protrusion 207, and the inner cover 1 form a steam passage, which is equivalent to integrally forming the steam valve with the front cover 2 or the inner cover 1. Compared with the related art, the steam valve is reduced, the number of parts is reduced, and the assembly process is simplified. Since the sealing structure 3 is arranged between the inner cover 1 and the first protrusion 207, 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, the front cover 2 and the inner cover 1 are sealed, preventing steam from entering the electrical components arranged between the front cover 2 and the inner cover 1 through the gap between the first protrusion 207 and the inner cover 1.

[0100] Specifically in one embodiment, the cooking appliance is an electric rice cooker or a pressure cooker.
