Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and particularly to an upper cover assembly of a cooking appliance and a cooking appliance. Background Art

[0002] In existing micro-pressure cooking appliances, such as micro-pressure electric steamers, silicone or metal balls are generally used as valve cores. When the set pressure is exceeded, the valve core is pushed open for exhaust, so that the cooking appliance can maintain a micro-pressure state. However, such cooking appliances only have one state of micro-pressure and cannot switch between micro-pressure and normal pressure, resulting in a single cooking mode. Summary of the Utility Model

[0003] Based on this, it is necessary to provide an upper cover assembly of a cooking appliance and a cooking appliance that can realize the switching between micro-pressure and normal pressure.

[0004] An upper cover assembly of a cooking appliance for covering a cooking cavity of the cooking appliance includes a cover body and a micro-pressure valve. The cover body is provided with an installation hole. The micro-pressure valve includes a valve body, a valve cover and a valve core. The valve body passes through the installation hole and is sealingly connected to the installation hole. A valve cavity is provided in the valve body. An air inlet communicating with the valve cavity is provided at the lower end of the valve body. The valve cover is rotatably covered on the upper end of the valve body. An exhaust port communicating with the valve cavity is provided on the valve cover. A fixing portion is provided in the valve cover and extends into the valve cavity. The valve core is fixed to the fixing portion and is disposed against the air inlet. The valve core is provided with an air outlet. By rotating the valve cover, the air outlet can be communicated with the air inlet or the air outlet can be offset from the air inlet. When the air outlet is communicated with the air inlet, the cooking cavity is in a normal-pressure cooking state. When the air outlet is offset from the air inlet, the cooking cavity is in a micro-pressure cooking state.

[0005] The upper cover assembly of the cooking appliance provided by the present application is provided with a micro-pressure valve. The micro-pressure valve includes a valve body, a valve cover and a valve core. By rotating the valve cover, the valve core can be driven to rotate, so that the air outlet is communicated with or offset from the air inlet, thereby realizing the switching between the micro-pressure cooking state and the normal-pressure cooking state, expanding the cooking mode, being applicable to the cooking of different ingredients, and thus improving the user experience.

[0006] In one embodiment, a plurality of air inlets are provided and are spaced along the circumferential direction of the valve body. A plurality of air outlets are provided and are spaced along the circumferential direction of the valve core. The plurality of air outlets correspond to the plurality of air inlets one by one.

[0007] In this way, the structure is very simple. By rotating the valve cover to drive the valve core to rotate, the air outlet can be aligned with the air inlet, so that the air outlet is communicated with the air inlet. When the air outlet rotates to the interval area between two air inlets, the air outlet is offset from the air inlet, so that the valve core closes the air inlet.

[0008] In one embodiment, the fixing part includes a rod part and a clamping joint provided at one end of the rod part. A clamping groove is provided at the center of the valve core, and the clamping joint is clamped in the clamping groove. A plurality of air outlets are provided and are arranged at intervals around the clamping groove.

[0009] In this way, the valve core and the fixing part are connected by clamping, the connection structure is simple, and the air outlets are not blocked.

[0010] In one embodiment, a limiting groove is provided on the valve core, and a limiting rib is provided on the rod part. The limiting rib is snapped into the limiting groove to limit the relative rotation of the valve core with respect to the valve cover.

[0011] In this way, by providing the limiting rib and the limiting groove, the valve core and the valve cover are relatively fixed in the circumferential direction, thereby ensuring that the valve core rotates with the rotation of the valve cover.

[0012] In one embodiment, the valve core is made of soft silicone.

[0013] In this way, the valve core can close the air inlet by abutting against one side of the air inlet, with good sealing effect, and can be deformed under a certain pressure to open the air inlet. Thus, when the valve core closes the air inlet, the cooking cavity can be maintained within a preset pressure range to keep the micro-pressure cooking state.

[0014] In one embodiment, a first limiting protrusion is provided on the outer wall of the valve body, and a second limiting protrusion is provided on the inner wall of the valve cover. The second limiting protrusion is stuck on one side of the first limiting protrusion close to the cover body to limit the axial detachment of the valve cover from the valve body.

[0015] In this way, by providing the first limiting protrusion and the second limiting protrusion, it does not affect the relative rotation of the valve cover with respect to the valve body, and at the same time, the valve cover can be prevented from detaching from the valve body when rotating.

[0016] In one embodiment, one of the first limiting protrusion and the second limiting protrusion is set as a convex ring, and the other is set as a plurality of spaced convex points or convex segments.

[0017] In this way, the plurality of spaced convex points or convex segments can make the valve cover or the valve body have a small amount of elasticity, so that when the valve cover is installed on the valve body, the second limiting protrusion can more easily cross the first limiting protrusion and be stuck on one side of the first limiting protrusion close to the cover body. It can be seen that the first limiting protrusion and the second limiting protrusion in this embodiment have a simple structure and are convenient to install.

[0018] In one embodiment, the valve body is provided with a rotation positioning groove, and the valve cover is provided with a rotation positioning protrusion, and the rotation positioning protrusion extends into the rotation positioning groove and can move in the rotation positioning groove to limit the rotation angle of the valve cover relative to the valve body.

[0019] In this way, the rotation positioning groove and the rotation positioning protrusion can be provided to limit the rotation angle of the valve cover relative to the valve body, thereby preventing the user from being unclear about the rotation angle when switching between the normal pressure cooking state and the micro-pressure cooking state.

[0020] In one of the embodiments, an annular mounting groove is provided on the outer wall of the valve body, a sealing ring is provided in the mounting groove, and the valve body is sealed and connected to the mounting hole through the sealing ring.

[0021] In this way, the provision of the sealing ring avoids air leakage between the valve body and the mounting hole, thereby ensuring the sealing effect between the valve body and the mounting hole.

[0022] The present application also provides a cooking utensil, comprising the upper cover assembly of the cooking utensil mentioned above, wherein the cooking utensil is a steamer, a stew pot, a frying pan or an electric rice cooker.

[0023] The cooking utensil is provided with the above-mentioned upper cover assembly, and the valve core can be driven to rotate by rotating the valve cover, so that the air outlet and the air inlet are connected or staggered, thereby realizing the switching between the micro-pressure cooking state and the normal pressure cooking state, expanding the cooking mode, and being suitable for cooking different ingredients, thereby improving the user experience.

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0038] See also Figures 1 to 3 The present application provides a cover assembly 100 of a cooking utensil, which is used to cover a cooking cavity 201 of the cooking utensil. The cover assembly 100 includes a cover body 10 and a micro-pressure valve 20. The cover body 10 is provided with a mounting hole 11, and the micro-pressure valve 20 is installed in the mounting hole 11. The micro-pressure valve 20 includes a valve body 21, a valve cover 22 and a valve core 23. The valve body 21 is penetrated through the mounting hole 11 and is sealed and connected to the mounting hole 11. A valve cavity 211 is provided in the valve body 21, and an air inlet 212 communicating with the valve cavity 211 is provided at the lower end of the valve body 21. The valve cover 22 is rotatably covered on the upper end of the valve body 21. The valve cover 22 is provided with an exhaust port 221 communicating with the valve cavity 211. A fixing portion 222 is provided inside the valve cover 22. The fixing portion 222 extends into the valve cavity 211. The valve core 23 is fixed to the fixing portion 222 and is arranged close to the air inlet 212. In this way, the valve core 23 can rotate with the rotation of the valve cover 22. The valve core 23 is provided with an air outlet 231. By rotating the valve cover 22, the air outlet 231 can be communicated with the air inlet 212, or the air outlet 231 can be staggered with the air inlet 212. When the air outlet 231 is communicated with the air inlet 212, the cooking cavity 201 is in a normal pressure cooking state; when the air outlet 231 is staggered with the air inlet 212, the cooking cavity 201 is in a micro-pressure cooking state. It can be seen that the upper cover assembly 100 of the cooking utensil provided in the present application is provided with a micro-pressure valve 20, and the micro-pressure valve 20 includes a valve body 21, a valve cover 22 and a valve core 23. By rotating the valve cover 22, the valve core 23 can be driven to rotate, so that the air outlet 231 is connected or staggered with the air inlet 212, thereby realizing the switching between the micro-pressure cooking state and the normal pressure cooking state, expanding the cooking mode, and being suitable for cooking different ingredients, thereby improving the user experience.

[0039] In this embodiment, the valve cavity 211 penetrates through the upper end surface of the valve body 21, and the exhaust port 221 is provided on the top wall of the valve cover 22. In this way, when the air outlet 231 is communicated with the air inlet 212, the steam is ejected from the top of the valve cover 22. Of course, in other embodiments, the valve cavity 211 may not penetrate through the upper end surface of the valve body 21, as long as the exhaust port 221 and the valve cavity 211 remain in communication.

[0040] Please refer to Figures 4 to 7 , further, a plurality of air inlets 212 are provided and are arranged at intervals along the circumferential direction of the valve body 21, a plurality of air outlets 231 are provided and are arranged at intervals along the circumferential direction of the valve core 23, and the plurality of air outlets 231 correspond to the plurality of air inlets 212 one by one. In this way, the structure is very simple. By rotating the valve cover 22 to drive the valve core 23 to rotate, the air outlet 231 can be aligned with the air inlet 212, so that the air outlet 231 is communicated with the air inlet 212. When the air outlet 231 rotates to the interval area between two air inlets 212, the air outlet 231 is staggered from the air inlet 212, so that the valve core 23 closes the air inlet 212.

[0041] In this embodiment, the air inlets 212 and the air outlets 231 are the same in shape and size, and both the air inlets 212 and the air outlets 231 are fan-shaped, and the structure is very simple. When the air outlet 231 and the air inlet 212 are aligned, the flow rate is the largest, which is beneficial to the rapid exhaust of the cooking cavity 201.

[0042] As Figure 4 shown, the number of the exhaust ports 221 is also multiple, and the multiple exhaust ports 221 are arranged at intervals along the circumferential direction of the valve cover 22. In this embodiment, the number of the exhaust ports 221 is the same as the number of the air outlets 231, and the exhaust ports 221 correspond to the air outlets 231 one by one. In the orthographic projection on the horizontal plane, the exhaust ports 221 and the air outlets 231, that is, the shapes and sizes of the exhaust ports 221 are the same as those of the air outlets 231. In this embodiment, the exhaust ports 221 are fan-shaped. In this way, when the air outlet 231 is communicated with the air inlet 212, the gas can directly flow upward into the valve cavity 211 and be discharged from the exhaust ports 221, and the gas discharge is very smooth. However, it is not limited to this. In other embodiments, the exhaust ports 221 may also be set to other shapes and sizes, as long as the exhaust ports 221 are communicated with the valve cavity 211.

[0043] Further, please refer to Figure 4 and Figure 5 , the fixing part 222 includes a rod part 2221 and a clamping head 2222 provided at one end of the rod part 2221. A clamping groove 232 is provided at the center of the valve core 23, and the clamping head 2222 is clamped in the clamping groove 232. A plurality of air outlets 231 are provided and are arranged at intervals around the clamping groove 232. In this way, the valve core 23 and the fixing part 222 are connected by clamping, the connection structure is simple, and the air outlets 231 are not blocked.

[0044] Further, please refer to Figure 4 and Figure 7 . A limiting groove 233 is provided on the valve core 23, and a limiting rib 2223 is provided on the rod portion 2221. The limiting rib 2223 is snapped into the limiting groove 233 to limit the relative rotation of the valve core 23 with respect to the valve cover 22. In this way, by providing the limiting rib 2223 and the limiting groove 233, the valve core 23 and the valve cover 22 are relatively fixed in the circumferential direction, thereby ensuring that the valve core 23 rotates with the rotation of the valve cover 22. In this embodiment, the opening of the limiting groove 233 faces upward. During installation, first align the limiting rib 2223 and the limiting groove 233, and then snap the clamping joint 2222 into the clamping groove 232, and the valve core 23 can be installed on the fixing portion 222. The installation process is very simple.

[0045] In this embodiment, the valve core 23 is made of soft silicone. The valve core 23 can close the air inlet 212 by abutting against one side of the air inlet 212, with good sealing effect, and can deform under a certain pressure to open the air inlet 212. Thus, when the valve core 23 closes the air inlet 212, the cooking cavity 201 can be maintained within a preset pressure range to keep the micro-pressure cooking state.

[0046] Further, please refer to Figure 4 and Figure 5 . A first limiting protrusion 213 is provided on the outer wall of the valve body 21, and a second limiting protrusion 223 is provided on the inner wall of the valve cover 22. The second limiting protrusion 223 is stuck on the side of the first limiting protrusion 213 close to the cover body 10 to limit the valve cover 22 from axially disengaging from the valve body 21. In this way, by providing the first limiting protrusion 213 and the second limiting protrusion 223, it does not affect the relative rotation of the valve cover 22 with respect to the valve body 21, and at the same time, the valve cover 22 can be prevented from disengaging from the valve body 21 during rotation.

[0047] Further, one of the first limiting protrusion 213 and the second limiting protrusion 223 is set as a convex ring, and the other is set as a plurality of spaced convex points or convex segments. In this way, the plurality of spaced convex points or convex segments can make the valve cover 22 or the valve body 21 have a small amount of elasticity. Thus, when the valve cover 22 is installed on the valve body 21, the second limiting protrusion 223 can more easily cross the first limiting protrusion 213 and be stuck on the side of the first limiting protrusion 213 close to the cover body 10. It can be seen that the structures of the first limiting protrusion 213 and the second limiting protrusion 223 in this embodiment are simple and convenient for installation. If both the first limiting protrusion and the second limiting protrusion are set as convex rings, it is very difficult for the second limiting protrusion to cross the first limiting protrusion and be stuck on the side of the first limiting protrusion close to the cover body, and the installation is relatively difficult. In this embodiment, the first limiting protrusion 213 is set as a convex ring, and the second limiting protrusion 223 is set as a plurality of spaced convex points or convex segments.

[0048] It can be understood that characters and / or patterns can be provided on the cover body 10 to indicate the way of switching between the normal pressure cooking state and the low pressure cooking state. For example, an arrow can be provided to indicate the rotation direction of the valve cover 22.

[0049] Further, please refer to Figure 4 and Figure 5 As shown, the valve body 21 is provided with a rotation positioning groove 214, and the valve cover 22 is provided with a rotation positioning protrusion 224. The rotation positioning protrusion 224 extends into the rotation positioning groove 214 and can move within the rotation positioning groove 214 to limit the rotation angle of the valve cover 22 relative to the valve body 21. In this way, by providing the rotation positioning groove 214 and the rotation positioning protrusion 224, the rotation angle of the valve cover 22 relative to the valve body 21 can be limited, preventing the user from being unclear about the rotation angle when switching between the normal pressure cooking state and the low pressure cooking state. In this embodiment, when the rotation positioning protrusion 224 abuts against one side wall of the rotation positioning groove 214, the air outlet 231 is aligned with the air inlet 212, so that the air outlet 231 communicates with the air inlet 212, and the gas in the cooking cavity 201 can sequentially pass through the air inlet 212, the air outlet 231, the valve cavity 211, and the exhaust port 221 and finally be discharged into the atmosphere, so that the cooking cavity 201 is in the normal pressure cooking state. When the rotation positioning protrusion 224 abuts against the other side wall of the rotation positioning groove 214, the air outlet 231 is offset from the air inlet 212, so that the valve core 23 closes the air inlet 212. When the pressure in the cooking cavity 201 exceeds the preset pressure, the gas in the cooking cavity 201 deforms the valve core 23 to open the air inlet 212 for exhaust, so that the cooking cavity 201 is always maintained within the preset pressure range. At this time, the cooking cavity 201 is in the low pressure cooking state.

[0050] In this embodiment, the rotation positioning groove 214 is provided at the upper end of the valve body 21, and the rotation positioning protrusion 224 extends downward from the top wall of the valve cover 22. In this way, the structure is very simple. During installation, first align the rotation positioning protrusion 224 and the rotation positioning groove 214, and then press the valve cover 22 downward, so that the second limit protrusion 223 can be pressed below the first limit protrusion 213, and thus the installation of the valve cover 22 can be completed. The installation process is very simple.

[0051] Further, please refer to Figures 3 to 5 As shown, an annular installation groove 215 is provided on the outer wall of the valve body 21, and a sealing ring 25 is provided in the installation groove 215. The valve body 21 is hermetically connected to the installation hole 11 through the sealing ring 25. In this way, by providing the sealing ring 25, air leakage between the valve body 21 and the installation hole 11 is avoided, ensuring the sealing effect between the valve body 21 and the installation hole 11.

[0052] In this embodiment, a sealing groove 251 is provided on the outside of the sealing ring 25, and the cover body 10 is partially inserted into the sealing groove 251. As shown in the figure, the cross section of the sealing ring 25 is C-shaped, so that the sealing effect is better, and the sealing ring 25 plays a limiting role in the installation of the valve body 21, which can prevent the valve body 21 from falling off from the installation hole 11. In this embodiment, the sealing ring 25 is hard silicone, which not only has a good sealing effect, but also can use its own strength to fix the valve body 21 on the cover body 10.

[0053] like Figure 1 and Figure 2 As shown, the present application also provides a cooking utensil, comprising the upper cover assembly 100, the cooking utensil further comprising a cooking body 200, the cooking body 200 being provided with a cooking cavity 201, the upper cover assembly 100 covering the cooking body 200 and covering the cooking cavity 201. The cooking utensil is provided with the upper cover assembly 100, and the valve core 23 can be driven to rotate by rotating the valve cover 22, so that the air outlet 231 is connected to or staggered with the air inlet 212, thereby realizing the switching between the micro-pressure cooking state and the normal pressure cooking state, expanding the cooking mode, and being applicable to the cooking of different ingredients, thereby improving the user experience.

[0054] In this embodiment, the cooking utensil is a steamer, but is not limited thereto. In other embodiments, the cooking utensil may also be other types of cooking utensil such as a stew pot, a frying pan or an electric rice cooker.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
