Abstract
Description
Technical Field
[0001] This application relates to the field of kitchen appliance technology, and in particular to a cooking appliance. Background Technology
[0002] Pressure cookers, such as pressure frying pans, typically have a sealing ring around the edge of the lid. This ring creates a tight seal between the lid and the pot body, and a pressure valve enables low-pressure cooking. When the heat is high (or the heating power is high), the pressure release rate of the pressure valve is less than the pressure increase rate inside the pot, causing the lid to lift and participate in the pressure release. During use, condensation forms on the inner wall of the lid and flows down to the edge. As the lid lifts to release pressure, this condensation can easily spray out from the edge of the lid. This hot condensation can easily burn the user. Utility Model Content
[0003] Therefore, it is necessary to provide a cooking appliance that can reduce the amount of condensation sprayed out.
[0004] A cooking appliance includes a pot body and a pot lid. The pot lid includes a lid body and a sealing element disposed on the peripheral edge of the lid body. The sealing element includes a sealing body and a sealing skirt. The sealing body wraps around the peripheral edge of the lid body, and the sealing skirt is disposed on one side of the sealing body. A limiting step is provided on the inner wall of the opening of the pot body. When the pot lid is closed on the pot body, the sealing body extends at least partially into the opening of the pot body, and the sealing skirt rests on the limiting step.
[0005] The cooking appliance provided in this application, by setting a limiting step on the inner wall of the pot and providing a sealing element with a sealing body and a sealing skirt, with the sealing body covering the peripheral edge of the lid, forms a good seal between the lid and the sealing element, preventing condensate from spraying out between them. Furthermore, when the lid is closed, the sealing body extends at least partially into the opening of the pot, and the sealing skirt rests against the limiting step. The contact point between the sealing skirt and the limiting step is a certain distance from the edge of the pot opening. When the lid is lifted by steam to release pressure, condensate impacts the sealing skirt and sprays outwards. The sealing body's obstruction of the sealing skirt buffers the impact force of the sprayed condensate. Simultaneously, the inner wall of the pot above the limiting step also provides some obstruction, making it less likely for condensate to spray outwards, thus reducing the risk of scalding the user from sprayed condensate.
[0006] In one embodiment, the sealing skirt is connected to the lower part of the sealing body, and the connecting end is located on the side of the sealing body near the center of the lid. The sealing skirt is inclined downward from the connecting end to the free end in a direction away from the center of the lid.
[0007] With this design, when the lid is closed on the pot body, the weight of the lid causes the sealing skirt to undergo a certain degree of elastic deformation, which helps to form a good sealing fit between the sealing skirt and the limiting step on the pot body. At the same time, the inclined sealing skirt can better prevent steam and condensate from splashing outwards.
[0008] In one embodiment, the seal further includes a guide rib protruding downward from the lower surface of the sealing skirt, the upper end of the guide rib being connected to the bottom surface of the sealing body and located on the side of the sealing skirt near the center of the cover; or the upper end of the guide rib being connected to the connection between the sealing skirt and the sealing body; or the upper end of the guide rib being connected to the lower surface of the sealing skirt.
[0009] In this way, by setting the guide ribs, the condensate on the inner wall of the lid can drip down along the guide ribs, thereby further reducing the probability of condensate spraying out between the seal and the pot body, and further reducing the risk of condensate splashing and scalding people during use.
[0010] In one embodiment, the height of the guide rib protruding from the lower surface of the sealing skirt is H, where 0.5mm ≤ H ≤ 5mm.
[0011] This ensures that condensate will not overflow the guide ribs and spread to the sealing skirt, while also preventing unnecessary material waste.
[0012] In one embodiment, the horizontal distance between the guide rib and the inner wall of the pot below the limiting step is L, where 1mm≤L≤10mm.
[0013] In this way, it is ensured that condensate is not easily splashed onto the limiting step and thus not easily sprayed out of the pot, while also avoiding unnecessary material waste. In addition, less condensate forms on the lower surface of the seal between the guide rib and the limiting step.
[0014] In one embodiment, the bottom surface of the sealing body is provided with a raised rib, the raised rib is located on the side of the sealing skirt away from the center of the cover, and the raised rib and the sealing skirt are spaced apart.
[0015] In this way, by setting ribs, the sealing skirt can be prevented from sticking to the bottom surface of the sealing body, thus ensuring that the sealing skirt has a certain degree of elasticity when the lid is closed on the pot body, so that the sealing skirt and the pot body form a good seal.
[0016] In one embodiment, the sealing body includes a first sidewall, a second sidewall, and a third sidewall connected in sequence. The first sidewall, the second sidewall, and the third sidewall form a slot. The peripheral edge of the cover is inserted into the slot. The first sidewall is located on the upper side of the cover, the third sidewall is located on the lower side of the cover, and the sealing skirt is connected to the third sidewall.
[0017] In this way, the sealing body can well wrap around the edge of the cover, so that a good seal is formed between the sealing body and the cover, and the seal is not easy to fall off the cover.
[0018] In one embodiment, the third sidewall includes a first part and a second part, with the two ends of the first part connected to the second sidewall and the second part respectively. The first part extends horizontally, and the end of the second part away from the first part extends upward and abuts against the cover, so that the third sidewall and the cover form a cavity with a wedge-shaped cross-section.
[0019] In this way, the edge of the third sidewall, i.e. the second part, can fit tightly against the cover, while saving on the material used for the seal.
[0020] In one embodiment, the upper surface of the third sidewall is attached to the lower surface of the cover, and the lower surface of the third sidewall extends horizontally.
[0021] In this way, the sealing body can also wrap the edge of the cover well, so that a good seal is formed between the sealing body and the cover, and the seal is not easy to fall off the cover.
[0022] In one embodiment, the seal is a silicone sealant.
[0023] In this way, it has a good sealing effect, high temperature resistance, and long service life. Attached Figure Description

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0035] Please see Figures 1 to 3 This application provides a cooking appliance, including a pot body 10 and a pot lid 20. The pot lid 20 includes a lid body 21 and a sealing element 30 disposed on the peripheral edge of the lid body 21. The sealing element 30 includes a sealing body 31 and a sealing skirt 32. The sealing body 31 covers the peripheral edge of the lid body 21, and the sealing skirt 32 is disposed on one side of the sealing body 31. A limiting step 11 is provided on the inner wall of the opening of the pot body 10. When the pot lid 20 is closed on the pot body 10, the sealing body 31 extends at least partially into the opening of the pot body 10, and the sealing skirt 32 rests on the limiting step 11. The cooking appliance provided by this application, by providing a limiting step 11 on the inner wall of the pot body 10, and by providing a sealing body 31 and a sealing skirt 32 on the sealing element 30, with the sealing body 31 covering the peripheral edge of the lid body 21, forms a good seal between the lid body 21 and the sealing element 30, preventing condensate from spraying out from between the lid body 21 and the sealing element 30. Furthermore, when the lid 20 is closed on the pot body 10, the sealing body 31 extends at least partially into the opening of the pot body 10, and the sealing skirt 32 rests against the limiting step 11. The contact position between the sealing skirt 32 and the limiting step 11 is a certain distance from the edge of the opening of the pot body 10. When the lid 20 is lifted by steam to participate in the pressure relief, the condensate impacts the sealing skirt 32 and sprays outward. Due to the obstruction of the sealing skirt 32 by the sealing body 31, the sealing skirt 32 can buffer the impact force of the condensate spraying outward. At the same time, the inner wall of the pot body 10 on the upper side of the limiting step 11 plays a certain role in obstructing the condensate, making it difficult for the condensate to spray outward, thereby reducing the risk of condensate spraying outward and scalding the user.
[0036] Furthermore, the sealing skirt 32 is connected to the lower part of the sealing body 31, with the connecting end located on the side of the sealing body 31 closer to the center of the lid 21. The sealing skirt 32 is inclined downwards from the connecting end to the free end, moving away from the center of the lid 20. It can be understood that the connecting end of the sealing skirt 32 refers to the end where the sealing skirt 32 connects to the sealing body 31, and the free end of the sealing skirt 32 refers to the end where the sealing skirt 32 rests on the limiting step 11. Thus, when the lid 20 is closed on the pot body 10, the gravity of the lid 21 causes the sealing skirt 32 to undergo a certain elastic deformation, which is beneficial for the sealing skirt 32 and the limiting step 11 on the pot body 10 to form a good sealing fit. At the same time, the inclined sealing skirt 32 can better prevent steam and condensate from splashing outwards.
[0037] Furthermore, the sealing element 30 also includes a guide rib 33 protruding downwards from the lower surface of the sealing skirt 32. By providing the guide rib 33, condensate on the inner wall of the lid 21 can drip downwards along the guide rib 33, thereby further reducing the probability of condensate spraying out between the sealing element 30 and the pot body 10, and further reducing the risk of scalding from condensate splashing during use. Figure 3 As shown, circle S represents condensate, and arrow SL represents the condensate flow path. It can be seen that the condensate on the lid 21 drips down along the guide ribs 33 into the pot body 10. In one embodiment, please refer to... Figure 3 The upper end of the guide rib 33 is connected to the bottom surface of the sealing body 31 and is located on the side of the sealing skirt 32 near the center of the cover 21. However, it is not limited to this. In another embodiment, the upper end of the guide rib 33 is connected to the connection between the sealing skirt 32 and the sealing body 31. In yet another embodiment, please refer to... Figure 4 The upper end of the guide rib 33 is connected to the lower surface of the sealing skirt 32. In this way, the guide rib 33 in the above three embodiments can guide the condensate downward into the pot body 10, thereby reducing or even avoiding the probability of condensate spraying out from between the seal 30 and the pot body 10, and thus reducing the risk of condensate splashing and scalding people during use.
[0038] Please see Figure 2 Furthermore, the height H of the guide rib 33 protruding from the lower surface of the sealing skirt 32 is 0.5mm ≤ H ≤ 5mm. If the height H of the guide rib 33 protruding from the lower surface of the sealing skirt 32 is too small, condensate will easily overflow the guide rib 33 and spread onto the sealing skirt 32. If the height H of the guide rib 33 protruding from the lower surface of the sealing skirt 32 is too large, more material will be used for the sealing element 30, resulting in unnecessary waste and also affecting the aesthetic appearance of the lid 20. In this embodiment, 0.5mm ≤ H ≤ 5mm ensures that condensate will not overflow the guide rib 33 and spread onto the sealing skirt 32, while also avoiding unnecessary material waste.
[0039] Furthermore, the horizontal distance between the guide rib 33 and the inner wall of the pot body 10 below the limiting step 11 is L, where 1mm ≤ L ≤ 10mm. If L is too small, the condensate falling along the guide rib 33 will easily splash onto the limiting step 11 or even spray out of the pot body 10 under the action of steam. If L is too large, more material will be used for the sealing element 30, resulting in unnecessary waste. At the same time, condensate will easily form on the lower surface of the sealing element 30 between the guide rib 33 and the limiting step 11, and the guide rib 33 cannot effectively block the flow of condensate at this point. In this embodiment, 1mm ≤ L ≤ 10mm ensures that condensate is not easily splashed onto the limiting step 11 and thus not easily sprayed out of the pot body 10, while also avoiding unnecessary material waste. In addition, less condensate forms on the lower surface of the sealing element 30 between the guide rib 33 and the limiting step 11.
[0040] Furthermore, the bottom surface of the sealing body 31 is provided with a raised rib 34, which is located on the side of the sealing skirt 32 away from the center of the lid 21, and the raised rib 34 and the sealing skirt 32 are spaced apart. In this way, by providing the raised rib 34, the sealing skirt 32 can be prevented from sticking to the bottom surface of the sealing body 31, thereby ensuring that the sealing skirt 32 has a certain elasticity when the lid 20 is closed on the pot body 10, so that the sealing skirt 32 and the pot body 10 form a good seal.
[0041] In one embodiment, the sealing body 31 includes a first sidewall 311, a second sidewall 312, and a third sidewall 313 connected in sequence. The first sidewall 311, second sidewall 312, and third sidewall 313 form a groove 314. The peripheral edge of the cover 21 is inserted into the groove 314. The first sidewall 311 is located on the upper side of the cover 21, and the third sidewall 313 is located on the lower side of the cover 21. A sealing skirt 32 is connected to the third sidewall 313. Thus, the sealing body 31 can effectively wrap around the edge of the cover 21, forming a good seal between the sealing body 31 and the cover 21, and the sealing element 30 is not easily detached from the cover 21. Figure 2 As shown, the protruding rib 34 is provided on the bottom surface of the third side wall 313.
[0042] In one embodiment, the third sidewall 313 includes a first portion 3131 and a second portion 3132. The two ends of the first portion 3131 are respectively connected to the second sidewall 312 and the second portion 3132. The first portion 3131 extends horizontally, and the end of the second portion 3132 away from the first portion 3131 extends upward and abuts against the cover 21, so that the third sidewall 313 and the cover 21 form a wedge-shaped cavity. Thus, the edge of the third sidewall 313, i.e., the second portion 3132, can fit tightly against the cover 21, while saving material on the sealing element 30. However, this is not a limitation. In another embodiment, the wedge-shaped cavity may not be provided; that is, the upper surface of the third sidewall 313 fits against the lower surface of the cover 21, and the lower surface of the third sidewall 313 extends horizontally. In this way, the sealing body 31 can also wrap the edge of the cover 21 well, so that a good seal is formed between the sealing body 31 and the cover 21, and the sealing element 30 is not easy to fall off the cover 21.
[0043] In this embodiment, the sealing element 30 is a silicone element, which has good sealing effect, high temperature resistance, and long service life.
[0044] The cooking appliance can be any cooking appliance with a pot body 10 and a pot lid 20, such as a wok, stew pot, rice cooker, and pressure cooker. This application does not limit this.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
