Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a steam cover and a cooking appliance having the same. Background Technology

[0002] Electric pressure cookers, rice cookers, and multi-functional pots with stewing functions are collectively referred to as cooking appliances. They can perform various cooking operations such as steaming, boiling, and stewing, greatly shortening cooking time and making people's lives more convenient.

[0003] In related technologies, in order to ensure the consistency of the appearance of cooking utensils, a steam cover is generally provided on its top cover to block the pressure relief valve of the cooking utensils and to allow steam to escape through the holes on the steam cover.

[0004] However, existing steam covers have a high temperature due to the direct contact of steam with their inner wall, which can easily burn users. Utility Model Content

[0005] This invention provides a steam cover and a cooking appliance having the same, to solve the problem of high temperature in steam covers in related technologies.

[0006] According to one aspect of the present invention, a steam cover is provided, comprising: a lower cover having an exhaust port disposed at the top of the lower cover, the lower cover having a receiving cavity for accommodating a valve body, the receiving cavity communicating with the exhaust port, and a cover body connecting portion further provided on the lower cover; and an upper cover covering the lower cover, the upper cover having a through-hole communicating with the exhaust port, the lower part of the upper cover fitting together with the lower part of the lower cover, and the top part of the upper cover fitting together with the top part of the lower cover, so that a hollow heat insulation cavity is formed between the upper cover and the lower cover, and the heat insulation cavity is isolated from the exhaust port.

[0007] The steam cover of this invention includes a lower cover and an upper cover. Steam in the cooking chamber is discharged through a valve body into the receiving cavity of the lower cover, and then discharged outside the cover body through an exhaust port communicating with the receiving cavity and an avoidance hole communicating with the exhaust port. Since the lower parts of the upper cover and the lower cover are fitted together, and the top parts of the upper cover and the lower cover are fitted together, a hollow heat-insulating cavity is formed between the upper and lower covers. The heat-insulating cavity is isolated from the exhaust port. By setting the heat-insulating cavity, the heat transferred from the steam and the lower cover to the upper cover is greatly reduced, thereby lowering the temperature of the upper cover.

[0008] Furthermore, the upper cover includes a top shielding plate and a first side plate connected to the outer edge of the top shielding plate. A clearance hole is provided through the top shielding plate. Both the top shielding plate and the first side plate are fitted against the outer wall of the lower cover. The inner wall of the top shielding plate, the inner wall of the first side plate, and the outer wall of the lower cover together form a heat insulation cavity. With this configuration, by ensuring that neither the top shielding plate nor the first side plate contacts the outer wall of the lower cover, the top and sides of the upper cover will not contact the lower cover, significantly reducing the heat transferred to the top and sides of the upper cover, resulting in lower temperatures at the top and sides of the upper cover.

[0009] Furthermore, the lower cover includes a second side plate, a middle connecting plate, and an exhaust top plate. The two ends of the middle connecting plate are connected to the upper end of the second side plate and the outer edge of the exhaust top plate, respectively. An exhaust port is located on the exhaust top plate. A first side plate surrounds the outer periphery of the second side plate, and a shielding top plate is positioned above the middle connecting plate. The inner wall of the shielding top plate, the inner wall of the first side plate, and the outer wall of the middle connecting plate together form a heat insulation cavity. The lower cover with this structure, utilizing the bonding of the first and second side plates, the bonding of the shielding top plate and the exhaust top plate, and the formation of a heat insulation cavity using the shielding top plate, the first side plate, and the middle connecting plate, offers advantages such as simple structure and ease of installation.

[0010] Furthermore, the exhaust top plate is positioned within the clearance hole, and its upper surface is lower than that of the shielding top plate. This structure allows condensed water vapor to remain on the exhaust top plate, preventing steam or water vapor from accumulating on the upper surface of the shielding top plate, thus avoiding water leakage from the top cover.

[0011] Furthermore, the inner wall of the intermediate connecting plate is a conical guide surface, with the cross-sectional area gradually increasing from top to bottom. This conical guide surface guides the steam, allowing it to flow smoothly to the exhaust top plate for discharge.

[0012] Furthermore, the steam cover also includes a first sealing ring, which is disposed between the top shielding plate and the intermediate connecting plate. The first sealing ring is located on the outer periphery of the clearance hole, and the top shielding plate and the intermediate connecting plate are sealed together by the first sealing ring. The first sealing ring can seal the top shielding plate and the intermediate connecting plate, preventing gas discharged through the clearance hole from entering the heat insulation cavity and preventing moisture from affecting the clear display of decorative patterns or textures on the lower cover.

[0013] Furthermore, one of the inner walls of the top cover and the outer wall of the bottom cover is provided with a sealing protrusion, and the other of the inner walls of the top cover and the outer wall of the bottom cover is provided with a sealing groove. The first sealing ring is located in the sealing groove and fits against the sealing protrusion. With the above structure, the sealing area between the first sealing ring and the intermediate connecting plate can be increased by utilizing the sealing groove, and the sealing area between the first sealing ring and the top cover can be increased by utilizing the sealing protrusion, thereby enhancing the sealing effect.

[0014] Furthermore, one of the inner walls of the first side plate and the outer wall of the lower cover is provided with a positioning protrusion, and the other of the inner walls of the first side plate and the outer wall of the lower cover is provided with a positioning groove. The positioning protrusion is located in the positioning groove. By cooperating with the positioning protrusion and the positioning groove, the upper cover can be positioned on the lower cover to avoid relative movement between the upper and lower covers; and / or, the outer wall of the lower cover is provided with an annular boss, and the lower end of the first side plate abuts against the annular boss. The annular boss can support the upper cover.

[0015] Furthermore, the steam lid also includes a second sealing ring, which is located on the lower lid. This second sealing ring seals the lower lid and the lid body, preventing steam or condensation from entering the lid body and extending the lifespan of the cooking appliance. And / or, the upper lid is made of a transparent material, and the upper surface of the middle connecting plate of the lower lid has a decorative pattern or texture. By setting the decorative pattern or texture and making the upper lid transparent, the user can observe the decorative pattern or texture, improving the overall integrity of the steam lid and making it more aesthetically pleasing.

[0016] According to another aspect of this utility model, a cooking appliance is provided, comprising: a pot body; a lid body that is closable and can be placed on the pot body; and a steam lid disposed on the lid body, wherein the steam lid is the steam lid provided above. Steam in the cooking chamber of the cooking appliance is discharged through a valve body into the receiving cavity of the lower lid, and then discharged outside the lid body through an exhaust port communicating with the receiving cavity and a clearance hole communicating with the exhaust port. Since the lower parts of the upper lid and the lower lid are fitted together, and the top parts of the upper lid and the lower lid are fitted together, a hollow heat-insulating cavity is formed between the upper lid and the lower lid, and the heat-insulating cavity is isolated from the exhaust port. By providing the heat-insulating cavity, the heat transferred from the steam and the lower lid to the upper lid is greatly reduced, thereby lowering the temperature of the upper lid.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 7As shown, this embodiment of the present invention provides a steam cover, which includes a lower cover 10 and an upper cover 20. The lower cover 10 has an exhaust port 11, which is located on the top of the lower cover 10. The lower cover 10 has a receiving cavity for accommodating a valve body, which is connected to the exhaust port 11. The lower cover 10 is also provided with a cover body connecting part 12. The upper cover 20 covers the lower cover 10. The upper cover 20 has a through hole 21 that is connected to the exhaust port 11. The lower part of the upper cover 20 fits into the lower part of the lower cover 10, and the top of the upper cover 20 fits into the top of the lower cover 10, so that a hollow heat insulation cavity 22 is formed between the upper cover 20 and the lower cover 10. The heat insulation cavity 22 is isolated from the exhaust port 11.

[0033] Applying the technical solution of this utility model, the steam cover includes a lower cover 10 and an upper cover 20. Steam in the cooking chamber is discharged into the receiving cavity of the lower cover 10 through a valve body, and then discharged out of the cover body through an exhaust port 11 communicating with the receiving cavity and an avoidance hole 21 communicating with the exhaust port 11. Since the lower part of the upper cover 20 is in contact with the lower part of the lower cover 10, and the top of the upper cover 20 is in contact with the top of the lower cover 10, a hollow heat-insulating cavity 22 is formed between the upper cover 20 and the lower cover 10. The heat-insulating cavity 22 is isolated from the exhaust port 11. By setting the heat-insulating cavity 22, the heat transferred from the steam and the lower cover 10 to the upper cover 20 is greatly reduced, thereby lowering the temperature of the upper cover 20.

[0034] The exhaust port 11 includes two arc-shaped exhaust holes spaced apart along a first direction. The valve body consists of two pressure-limiting valves, with the two arc-shaped exhaust holes corresponding to the two pressure-limiting valves on the cover 50. The handle on the cover 50 and the steam cover are spaced apart along a second direction on the cover 50.

[0035] In this embodiment, the steam cap protrudes from the upper surface of the cap 50, and the distance between the outer wall of the upper cap 20 and the side wall of the handle on the cap 50 is about 15mm. When the user operates the handle, the upper cap 20 will not be touched, thus avoiding burns.

[0036] like Figure 1 As shown, the upper cover 20 includes a top shielding plate 23 and a first side plate 24 connected to the outer edge of the top shielding plate 23. A clearance hole 21 is provided through the top shielding plate 23. Both the top shielding plate 23 and the first side plate 24 are in contact with the outer wall of the lower cover 10. The inner wall of the top shielding plate 23, the inner wall of the first side plate 24, and the outer wall of the lower cover 10 together form a heat insulation cavity 22. With this arrangement, by ensuring that neither the top shielding plate 23 nor the first side plate 24 contacts the outer wall of the lower cover 10, the top and sides of the upper cover 20 will not contact the lower cover 10, greatly reducing the heat transferred to the top and sides of the upper cover 20, resulting in lower temperatures at the top and sides of the upper cover 20.

[0037] In other embodiments, the top cover 20 may also be configured as an arc-shaped cover.

[0038] In this embodiment, the inner wall of the top shield 23 is attached to the top of the lower cover 10, and the inner wall of the first side plate 24 is attached to the lower part of the lower cover 10.

[0039] like Figure 1 As shown, the lower cover 10 includes a second side plate 13, a middle connecting plate 14, and an exhaust top plate 15. The two ends of the middle connecting plate 14 are connected to the upper end of the second side plate 13 and the outer edge of the exhaust top plate 15, respectively. An exhaust port 11 is disposed on the exhaust top plate 15. A first side plate 24 surrounds the outer periphery of the second side plate 13. A shielding top plate 23 is disposed above the middle connecting plate 14. The inner wall of the shielding top plate 23, the inner wall of the first side plate 24, and the outer wall of the middle connecting plate 14 together form a heat insulation cavity 22. The lower cover 10 with the above structure utilizes the first side plate 24 and the second side plate 13 in contact, and the shielding top plate 23 and the exhaust top plate 15 in contact, forming a heat insulation cavity 22 using the shielding top plate 23, the first side plate 24, and the middle connecting plate 14. This structure is simple and easy to install.

[0040] like Figure 1 As shown, the exhaust top plate 15 is disposed within the clearance hole 21, and the upper surface of the exhaust top plate 15 is lower than the upper surface of the shielding top plate 23. With the above structure, the condensed water vapor can be retained on the exhaust top plate 15, preventing steam or water vapor from accumulating on the upper surface of the shielding top plate 23, thereby preventing water from flowing out from the top cover 20.

[0041] Furthermore, since the exhaust top plate 15 is located inside the clearance hole 21, the area of ​​the exhaust port 11 is much smaller than the area of ​​the clearance hole 21. When steam is discharged, it will not flow through the variable cross section, thereby reducing the noise generated by steam discharge and achieving the purpose of noise reduction.

[0042] like Figure 1 As shown, the inner wall of the intermediate connecting plate 14 is a conical guide surface 141, and the cross-sectional area of ​​the conical guide surface 141 gradually increases from top to bottom. The conical guide surface 141 can guide the steam, allowing the steam to flow smoothly to the exhaust top plate 15 for discharge.

[0043] In this embodiment, the conical guide surface 141 is an arc-shaped guide surface, and in order to increase the volume of the heat insulation cavity 22, the intermediate connecting plate 14 is recessed towards the inside of the lower cover 10.

[0044] The steam cover also includes a first sealing ring 30, which is disposed between the top shielding plate 23 and the intermediate connecting plate 14. The first sealing ring 30 is located on the outer periphery of the clearance hole 21, and the top shielding plate 23 and the intermediate connecting plate 14 are sealed together by the first sealing ring 30. The first sealing ring 30 can seal the top shielding plate 23 and the intermediate connecting plate 14, preventing gas discharged through the clearance hole 21 from entering the heat insulation cavity 22.

[0045] In other embodiments, the first sealing ring 30 may be disposed between the shielding top plate 23 and the exhaust top plate 15 to seal the shielding top plate 23 and the exhaust top plate 15.

[0046] like Figure 1 As shown, one of the inner walls of the top shield 23 and the outer wall of the lower cover 10 is provided with a sealing protrusion 25, and the other of the inner walls of the top shield 23 and the outer wall of the lower cover 10 is provided with a sealing groove 16. The first sealing ring 30 is located in the sealing groove 16 and fits against the sealing protrusion 25. With the above structure, the sealing area between the first sealing ring 30 and the intermediate connecting plate 14 can be increased by utilizing the sealing groove 16, and the sealing area between the first sealing ring 30 and the top shield 23 can be increased by utilizing the sealing protrusion 25, thereby enhancing the sealing effect.

[0047] like Figure 1 As shown, one of the inner walls of the first side plate 24 and the outer wall of the lower cover 10 is provided with a positioning protrusion 17, and the other of the inner walls of the first side plate 24 and the outer wall of the lower cover 10 is provided with a positioning groove 26. The positioning protrusion 17 is located in the positioning groove 26. By using the positioning protrusion 17 and the positioning groove 26 to cooperate, the upper cover 20 can be positioned on the lower cover 10 to avoid relative movement between the upper cover 20 and the lower cover 10.

[0048] like Figure 1 As shown, the outer wall of the lower cover 10 is provided with an annular boss 27, and the lower end of the first side plate 24 abuts against the annular boss 27. The annular boss 27 can support the upper cover 20.

[0049] In this embodiment, the lower end of the first side plate 24 is sandwiched between the positioning protrusion 17 and the annular protrusion 27, thereby firmly fixing the upper cover 20 to the lower cover 10.

[0050] like Figure 6 As shown, the steam lid also includes a second sealing ring 40, which is disposed on the lower cover 10. The second sealing ring 40 seals the lower cover 10 and the lid body 50, preventing steam or condensation from entering the lid body 50 and extending the lifespan of the cooking appliance.

[0051] The second sealing ring 40 is sealed and fitted to the outer wall of the lower cover 10 and the cover body 50 respectively.

[0052] In this embodiment, a receiving groove is provided at the lower end of the lower cover 10, and the second sealing ring 40 is located in the receiving groove.

[0053] Specifically, the top cover 20 is made of transparent material, and the upper surface of the middle connecting plate 14 is decorated with decorative patterns or textures. By setting decorative patterns or textures and making the top cover 20 transparent, users can observe the decorative patterns or textures, which can improve the overall integrity of the steam cover and make it more aesthetically pleasing.

[0054] The cover connecting part 12 includes a mounting protrusion inserted into the mounting groove of the cover 50. This mounting method, which uses a mounting protrusion that mates with the mounting groove, offers advantages such as simple structure and ease of operation.

[0055] In other embodiments, the cover connecting part 12 may also be a snap-fit ​​protrusion, and a snap-fit ​​groove is provided on the cover 50. By rotating the steam cover relative to the cover 50, the snap-fit ​​protrusion and the snap-fit ​​groove can be engaged.

[0056] like Figure 7 As shown, another embodiment of this utility model provides a cooking appliance, which includes a pot body, a lid 50, and a steam cover. The lid 50 is closable and covers the pot body. The steam cover is disposed on the lid 50 and is the steam cover provided above. Steam in the cooking chamber of the cooking appliance is discharged through a valve body into the receiving cavity of the lower cover 10, and is discharged out of the lid body through an exhaust port 11 communicating with the receiving cavity and an avoidance hole 21 communicating with the exhaust port 11. Since the lower part of the upper cover 20 and the lower part of the lower cover 10 are in contact with each other, and the top of the upper cover 20 and the top of the lower cover 10 are in contact with each other, a hollow heat insulation cavity 22 is formed between the upper cover 20 and the lower cover 10. The heat insulation cavity 22 is isolated from the exhaust port 11. By setting the heat insulation cavity 22, the heat transferred from the steam and the lower cover 10 to the upper cover 20 is greatly reduced, thereby lowering the temperature of the upper cover 20.

[0057] In this embodiment, the steam cover is detachably mounted on the cover body 50 to facilitate cleaning or observation by the user.

[0058] The cooking appliances include electric pressure cookers, rice cookers, and multi-functional cookers with pressure cooking functions.
