Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a pressure cooking appliance. Background Art

[0002] Pressure cooking appliances are typically equipped with multiple pressure-limiting protection structures. The first pressure-limiting protection is a pressure-limiting valve installed on the pot lid. When the pressure in the pot exceeds the set safety pressure, the pressure-limiting valve opens to release the pressure. If the pressure-limiting valve is blocked by food or fails, the pressure is released through the second pressure-limiting structure. The second pressure-limiting structure is formed by the sealing ring on the pot lid and the inner pot. As the pressure in the pot increases, the inner pot moves downward under the action of the air pressure, causing the distance between the inner pot and the pot lid to increase. The sealing ring will pop out from the gap between the two, connecting the cooking chamber to the outside atmosphere and thus releasing the pressure.

[0003] Some pressure cookers have lids that are pivotally connected to the pot body at the rear end and locked to the pot body at the front end via a buckle or other structure. As a result, the lid's front and rear ends are fixed to the pot body, and the lid's sealing ring experiences minimal deformation at these locations. However, on the left and right sides of the lid, where the lid and pot body are not fixed, the sealing ring experiences significant deformation.

[0004] Therefore, when the pressure-limiting valve on the pot lid fails, the gap between the pot and the lid widens, further increasing the deformation of the sealing rings on the left and right sides of the pot lid. This causes the sealing rings to pop out from the left and right sides of the pot lid first, meaning the pressure relief points are located on the left and right sides of the pot lid, and the hot gas in the pot is ejected from these two sides. Since the left and right sides of the pot lid are closer to the user or other kitchen components, there is a risk of burns from the hot gas during the pressure relief process, as well as damage to other kitchen components. Utility Model Content

[0005] The utility model provides a pressure cooking appliance to solve the problem that when the pressure limiting valve of the pot cover fails and the pressure in the pot exceeds the safety pressure, the left and right parts of the sealing ring are deformed first, so that the pressure relief positions are located on the left and right sides of the cooking appliance, which affects the user.

[0006] The technical solution adopted by this utility model is:

[0007] A pressure cooking device includes a pot body and a pot lid, wherein the pot body has a connecting end and an opening and closing end, wherein the connecting end is rotatably connected to the pot lid, and the opening and closing end can be locked with the pot lid. The pressure cooking device also includes an inner pot arranged inside the pot body, wherein the rim of the inner pot has an outer turning edge. The pressure cooking device also includes a support member, which is floatingly arranged at the connecting end, and the outer turning edge rests on the support member. The support member can move downward under the action of the outer turning edge to increase the distance between the outer turning edge and the pot lid.

[0008] The pressure cooking device of the present invention also has the following additional technical features:

[0009] The support member includes a support portion and an elastic portion. The support portion protrudes from the upper surface of the pot body. The upper end of the elastic portion acts on the support portion, and the lower end acts on the pot body, so that the support portion can float up and down under the elastic force of the elastic portion.

[0010] One of the support part and the pot body is provided with a limiting column, and the other one is provided with a limiting rib. A limiting space is formed between the limiting rib and the limiting column, and the elastic part is placed in the limiting space.

[0011] The pot body includes a middle ring and a decorative piece placed above the middle ring. The decorative piece has a supporting platform for supporting the outer flange. The supporting piece is arranged between the decorative piece and the middle ring, and the top of the supporting piece protrudes from the supporting platform.

[0012] The supporting platform is provided with a vertical through hole, and the support member passes through the through hole.

[0013] The lower surface of the outer flange has an abutting plane, and the top of the support member has a contact plane for abutting the abutting plane; or, the top of the support member is provided with a contact curved surface.

[0014] The pot cover is provided with a sealing member having a first sealing lip extending obliquely away from the center of the pot cover, and the first sealing lip abuts against the outer turning edge.

[0015] The sealing member also has a second sealing lip extending into the interior of the inner container, and the second sealing lip abuts against the inner side wall of the inner container for sealing.

[0016] The pot body has an opening for placing the inner pot, and a mounting portion protruding radially outward along the pot body is provided at the corresponding connecting end of the opening edge. There are two support members and they are arranged at both ends of the mounting portion along the circumference of the opening.

[0017] The pot body is provided with a support platform at the opening and closing end. When there is no pressure in the pot, the support surface of the support platform is flush with the upper edge of the support member.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the present invention, the support member is floatingly arranged at the connection end of the pot body. After the inner pot is placed in the pot body, the outer flange on the rear side of the inner pot rests on the support member. The support member supports the outer flange so that the seal on the pot lid can stably abut and seal against the outer flange. As the air pressure in the pot becomes higher and higher, the inner pot tends to move downward under the action of the air pressure, thereby forming a downward force on the support member, pressing the support member to move downward, thereby increasing the distance between the outer flange on the rear side of the inner pot and the pot lid. In the circumferential direction of the pot lid and the inner pot, the position with the largest gap is located at the rear side. At this time, the seal here will pop out under the action of the air pressure difference between the inside and outside of the pot, so that the inside of the pot is connected to the outside atmosphere for exhaust and pressure relief. In this way, the pressure relief position is located at the connection end, that is, the rear side of the pressure cooking appliance, to achieve directional pressure relief. At the same time, the rear side is also the side away from the user when the user uses the cooking appliance, which can avoid the impact of the ejected high-temperature gas on the user as much as possible, improve the user experience, and avoid the high-temperature gas from directly spraying onto the components on both sides of the pressure cooking appliance, reducing the impact of the high-temperature gas on other components in the kitchen.

[0020] 2. As a preferred embodiment of the present invention, the support member includes a support portion and an elastic portion. The support portion protrudes from the upper surface of the pot body. The upper end of the elastic portion acts on the support portion, and the lower end acts on the pot body, so that the support portion can float up and down under the elastic force of the elastic portion. The elastic force of the elastic portion provides upward support for the support portion, thereby supporting the outer flange of the inner pot. This not only improves the support force of the support portion on the inner pot, but also overcomes the elastic force of the elastic portion when the outer flange presses the support portion downward, causing the elastic portion to be compressed, making the elastic portion more responsive and facilitating the use of the elastic force of the elastic portion to limit the safety pressure within the pot. Furthermore, when the pressure within the pot returns to within the safety pressure, the elastic portion, under its own elastic force, pushes against the support portion, causing the outer flange to move upward and reset, thereby restoring contact between the seal and the outer flange, restoring the sealing of the cooking chamber, and allowing cooking to continue without manual reset, thereby improving cooking continuity.

[0021] 3. As a preferred embodiment of the present invention, the pot body includes a middle ring and a decorative piece placed above the middle ring, the decorative piece has a supporting platform for supporting the outer flange, the support piece is arranged between the decorative piece and the middle ring, and the top of the support piece protrudes from the supporting platform. The decorative piece is located above the middle ring and is used to support the outer flange of the inner pot. It can be made of a material with higher strength such as metal, thereby improving the structural stability and the support stability of the inner pot, and avoiding the inner pot pressing the middle ring to cause deformation of the middle ring. The supporting platform not only leaves space for the installation of the support piece, facilitating the installation of the support piece, but also when the outer flange on the rear side presses the support piece downward, the supporting platform can also support the outer flange after it moves downward, thereby controlling the tilt angle of the inner pot, always maintaining the stability of the inner pot, and avoiding excessive tilt angles that cause food inside the inner pot to leak.

[0022] 4. As a preferred embodiment of the present invention, the pot lid is provided with a sealing member having a first sealing lip extending obliquely away from the center of the pot lid, the first sealing lip abutting the outer rim. The first sealing lip extends obliquely outward. When the distance between the outer rim and the pot lid is small, the first sealing lip can firmly abut the outer rim, resulting in a high frictional resistance between the two, preventing the first sealing lip from springing open, thereby maintaining a seal within the pot. As the pressure within the pot gradually increases, the outer rim moves downward, increasing the distance between it and the pot lid. The frictional resistance between the first sealing lip and the outer rim also decreases, allowing the first sealing lip to spring outward under the action of the pot pressure, disengaging from the outer rim. This makes the first sealing lip more easily open, allowing it to quickly respond and release pressure when the pot pressure exceeds a set safety pressure value, ensuring safe cooking. When the pressure within the pot is released to below the set safety value, the first sealing lip rebounds under its own elastic force, re-engaging with the outer rim.

[0023] 5. As a preferred embodiment of the present invention, the seal further comprises a second sealing lip extending into the interior of the inner pot, the second sealing lip abutting and sealing against the inner sidewall of the inner pot. The second sealing lip extending into the interior of the inner pot and abutting against the inner sidewall of the inner pot can improve the sealing effect between the seal and the inner pot, thereby improving the sealing of the cooking cavity and ensuring reliable pressure cooking. Furthermore, as the air pressure in the pot increases, the second sealing lip will swing outward under the action of the air pressure, thereby tightly fitting against the inner sidewall of the inner pot, further improving the sealing performance. The higher the air pressure in the pot, the tighter the fit between the second sealing lip and the inner pot. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

In the description of this specification, the description with reference to the terms "implementation method", "embodiment", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0038] like Figure 1 As shown, a pressure cooking device includes a pot body 1 and a pot lid 2, the pot body 1 has a connecting end 12 and an opening and closing end 11, the connecting end 12 is rotatably connected to the pot lid 2, and the opening and closing end 11 can be locked with the pot lid 2, the pressure cooking device also includes an inner pot 3 placed inside the pot body 1, the edge of the inner pot 3 has an outer flange 31, the pressure cooking device also includes a support member 4, the support member 4 is floatingly arranged on the connecting end 12, the outer flange 31 rests on the support member 4, and the support member 4 can move downward under the action of the outer flange 31 to increase the distance between the outer flange 31 and the pot lid 2.

[0039] It is understood that the connecting end 12 corresponds to the rear end of the pressure cooking device, and the opening and closing end 11 corresponds to the front end of the pressure cooking device. When opening the lid, the front end of the pot lid 2 unlocks from the opening and closing end 11 and then flips upward and backward to open. The pot lid 2 is provided with a seal 21. When the pot lid 2 is closed, the seal 21 abuts against the upper surface of the outer flange 31, thereby sealing the cooking cavity. At this time, due to the small distance between the outer flange 31 and the pot lid 2, the two squeeze the seal 21, causing it to seal the gap between them and prevent it from popping open. As the air pressure in the pot increases, the inner pot 3 is pressed downward, the gap between the outer flange 31 and the pot lid 2 increases, and the squeezing force on the seal 21 decreases. At this time, the seal 21 can be pushed by the gas to pop open the abutment with the outer flange 31.

[0040] The support member 4 can be a structure independent of the pot body 1 and assembled and fixed to the connecting end 12, or the support member 4 can be set as a structure integrated with the pot body 1, which is not limited here.

[0041] In the present invention, the support member 4 is floatingly arranged at the connection end 12 of the pot body 1. After the inner pot 3 is placed in the pot body 1, the outer flange 31 on the rear side of the inner pot 3 rests on the support member 4. The support member 4 supports the outer flange 31 so that the seal 21 on the pot cover 2 is stably abutted and sealed with the outer flange 31. As the air pressure in the pot becomes higher and higher, the inner pot 3 tends to move downward under the action of the air pressure, thereby forming a downward force on the support member 4, pressing the support member 4 downward, thereby increasing the distance between the outer flange 31 on the rear side of the inner pot 3 and the pot cover 2. In the circumferential direction of the pot cover 2 and the inner pot 3, the largest gap is located at the rear side. At this time, the seal 21 here will pop out under the action of the air pressure difference between the inside and outside of the pot, so that the inside of the pot is connected to the outside atmosphere for exhaust and pressure relief. In this way, the pressure relief position is located at the connection end 12, that is, the rear side of the pressure cooking appliance, to achieve directional pressure relief. At the same time, the rear side is also the side away from the user when the user uses the cooking appliance, thereby avoiding the impact of the ejected high-temperature gas on the user as much as possible, improving the user experience, and avoiding the high-temperature gas from directly spraying onto the components on both sides of the pressure cooking appliance, reducing the impact of the high-temperature gas on other components in the kitchen.

[0042] It should be noted that the pressure cooking appliance of the present invention has a pressure limiting valve on the pot lid 2. When the air pressure in the pot exceeds the set safety pressure, the pressure is released first through the pressure limiting valve on the pot lid 2. When the pressure limiting valve fails and cannot exhaust, the pressure is released through the sealing member 21 on the rear side.

[0043] It should be noted that the present invention does not limit the structure of the support member 4. In one embodiment, the support member 4 is made of a material with elastic deformation ability such as silicone. When the outer flange 31 rests on the support member 4, the support member 4 can support the outer flange 31. As the downward pressure of the outer flange 31 becomes greater and greater, the support member 4 is pressed to undergo elastic deformation, thereby causing the outer flange 31 to move downward.

[0044] As a preferred embodiment of the present invention, Figure 1 、 Figure 3 As shown, the support member 4 includes a support portion 41 and an elastic portion 42. The support portion 41 protrudes from the upper surface of the pot body 1. The upper end of the elastic portion 42 acts on the support portion 41, and the lower end acts on the pot body 1, so that the support portion 41 can float up and down under the elastic force of the elastic portion 42.

[0045] The elastic force of the elastic portion 42 is utilized to form an upward support for the support portion 41, thereby enabling the support portion 41 to support the outer flange 31 of the inner pot 3. This not only improves the support force of the support portion 41 on the inner pot 3, but also overcomes the elastic force of the elastic portion 42 when the outer flange 31 presses the support portion 41 downward, causing the elastic portion 42 to be compressed, making the elastic portion 42 more responsive and facilitating the use of the elastic force of the elastic portion 42 to define a safe pressure within the pot. Furthermore, when the pressure within the pot returns to within the safe pressure, the elastic portion 42, under its own elastic force, pushes against the support portion 41, driving the outer flange 31 upward to reset, thereby restoring contact between the seal 21 and the outer flange 31, restoring the sealing of the cooking cavity, and allowing cooking to continue without manual reset, thereby improving cooking continuity.

[0046] Preferably, if Figure 1 As shown, the elastic portion 42 is a spring. In application, springs with different elastic coefficients can be selected to adjust the safety air pressure value.

[0047] Further, if Figure 2 、 Figure 3 As shown, one of the support portion 41 and the pot body 1 is provided with a limiting column 17, and the other is provided with a limiting rib 43. A limiting space 431 is formed between the limiting rib 43 and the limiting column 17, and the elastic portion 42 is placed in the limiting space 431.

[0048] One end of the elastic part 42 is sleeved on the outside of the limiting column 17, and the other end is surrounded by the limiting rib 43, thereby limiting the movement and deformation of the elastic part 42 to the limiting space 431 between the limiting rib 43 and the limiting column 17. On the one hand, the elastic part 42 can only be deformed in the vertical direction, and on the other hand, the posture of the elastic part 42 after deformation can be limited to improve the service life and reliability of the elastic part 42 and avoid damage.

[0049] Specifically, such as Figure 3 As shown, the pot body 1 is provided with an upwardly protruding limiting post 17, the lower end of the elastic portion 42 is sleeved on the outside of the limiting post 17, the support portion 41 is located above the elastic portion 42, and a limiting rib 43 is provided, and the top end of the elastic portion 42 is located in the space surrounded by the limiting rib 43. Of course, the limiting post 17 can also be provided on the support portion 41, and the limiting rib 43 can be provided on the pot body 1, which is not limited here.

[0050] In a preferred embodiment, Figure 1 、 Figure 3 As shown, the pot body 1 includes a middle ring 13 and a decorative piece 14 placed above the middle ring 13. The decorative piece 14 has a supporting platform 141 for supporting the outer flange 31. The support piece 4 is arranged between the decorative piece 14 and the middle ring 13, and the top of the support piece 4 protrudes from the supporting platform 141.

[0051] The decorative member 14 is located above the middle ring 13 and is used to support the outer flange 31 of the inner liner 3. It can be made of a high-strength material such as metal, thereby improving the structural stability and the support stability of the inner liner 3, and preventing the inner liner 3 from pressing on the middle ring 13 and causing deformation of the middle ring 13. The supporting platform 141 not only leaves space for the installation of the support member 4, facilitating the installation of the support member 4, but also when the outer flange 31 on the rear side presses the support member 4 downward, the supporting platform 141 can also support the outer flange 31 after it moves downward, thereby controlling the tilt angle of the inner liner 3, always maintaining the stability of the inner liner 3, and preventing the food inside the inner liner 3 from spilling due to excessive tilt angle.

[0052] In addition, the support member 4 is arranged between the decorative member 14 and the middle ring 13, with only a small top portion protruding from the decorative member 14, and a hidden design of the support member 4 is realized, with structures such as the elastic part 42 being accommodated between the decorative member 14 and the middle ring 13, which improves the appearance while ensuring cleanliness and reliability and smoothness of deformation or movement.

[0053] Specifically, the decorative member 14 is an annular structure, which is arranged at the edge of the opening of the middle ring 13 and is used to support the outer flange 31 of the inner liner 3. Figure 3 As shown, the decorative member 14 bulges upward to increase the distance between it and the middle ring 13 , leaving enough installation space for the support member 4 .

[0054] Furthermore, if Figure 1 、 Figure 3 As shown, the supporting platform 141 is provided with a vertical through hole 142 , and the support member 4 passes through the through hole 142 .

[0055] The support member 4 vertically passes through the through hole 142 , so that the through hole 142 can guide the up and down floating of the support member 4 and limit the support member 4 to move only in the vertical direction, further improving the movement reliability of the support member 4 .

[0056] Preferably, if Figure 3 As shown, the support member 4 has a first support portion and a second support portion. The first support portion passes through the through hole 142, and the second support portion is located between the decorative member 14 and the middle ring 13. The width of the second support portion is greater than that of the first support portion, so that it can form a stop with the decorative member 14 to limit the upward movement of the support member 4 and prevent the support member 4 from falling out of the through hole 142.

[0057] In one embodiment, if Figure 3 As shown, the lower surface of the outer flange 31 has an abutment plane, and the top of the support member 4 has a contact plane 44 for abutting the abutment plane. The support member 4 and the outer flange 31 are in plane contact, so that after the inner liner 3 is placed, there is surface contact between them, thereby increasing the contact area and improving support stability.

[0058] In another embodiment, a contact curved surface is provided on the top of the support member 4. As the air pressure in the pot becomes higher and higher, the downward pressure of the outer flange 31 on the support member 4 on the rear side becomes greater and greater, and then the outer flange 31 presses the support member 4 downward. However, at the opening and closing end 11 of the pot body 1, the outer flange 31 does not move downward. Therefore, the overall movement of the inner pot 3 is that the rear end swings downward around the front end, so that the inner pot 3 rotates from a horizontal posture to a slightly inclined posture. At this time, the outer flange 31 on the rear side rotates from a horizontal posture to an inclined posture, and the contact position with the support member 4 also changes. By setting the top of the support member 4 as a contact curved surface, after the inner pot 3 is tilted, the outer flange 31 on the rear side is always in stable contact with the support member 4.

[0059] Specifically, the contact curved surface can be an inclined surface, an arc surface or an irregular curved surface, etc., which is not limited here. Preferably, the inclined surface is high inside and low outside (higher on the side close to the center of the pot body 1 and lower on the side away from the center of the pot body 1).

[0060] As a preferred embodiment of the present invention, Figure 3 As shown, the pot cover 2 is provided with a sealing member 21 , which has a first sealing lip 211 extending obliquely away from the center of the pot cover 2 , and the first sealing lip 211 abuts against the outer flange 31 .

[0061] The first sealing lip 211 extends outward at an angle. When the distance between the outer flange 31 and the pot lid 2 is small, the first sealing lip 211 can firmly abut the outer flange 31. The frictional resistance between the two is large, preventing the first sealing lip 211 from springing open, thus maintaining the pot seal. As the pressure in the pot gradually increases, the outer flange 31 moves downward, increasing the distance between it and the pot lid 2. The frictional resistance between the first sealing lip 211 and the outer flange 31 also decreases, allowing the first sealing lip 211 to spring outward under the action of the air pressure in the pot, breaking away from the outer flange 31. This makes it easier for the first sealing lip 211 to spring open, allowing it to quickly respond and release pressure when the pressure in the pot exceeds the set safety pressure value, ensuring safe cooking. When the pressure in the pot is released to below the set safety value, the first sealing lip 211 rebounds under its own elastic force and returns to abutment with the outer flange 31.

[0062] Preferably, if Figure 3 As shown, the sealing member 21 further has a second sealing lip 212 extending into the interior of the inner container 3 , and the second sealing lip 212 abuts against the inner side wall of the inner container 3 for sealing.

[0063] Second sealing lip 212 extends into inner pot 3 and abuts against the inner wall of inner pot 3, enhancing the sealing effect between seal 21 and inner pot 3, thereby improving the sealing of the cooking cavity and ensuring reliable pressure cooking. Furthermore, as the pressure in the pot increases, second sealing lip 212 swings outward under the action of the pressure, tightly fitting against the inner wall of inner pot 3, further improving the sealing performance. Consequently, the higher the pressure in the pot, the tighter the fit between second sealing lip 212 and inner pot 3.

[0064] Preferably, if Figure 1 As shown, the pot body 1 has an opening for placing the inner pot 3, and a mounting portion 16 protruding radially outward along the pot body 1 is provided at the corresponding connection end 12 of the opening. There are two support members 4 and they are arranged at both ends of the mounting portion 16 along the circumference of the opening.

[0065] The mounting portion 16 protrudes radially outward, providing space for the installation of the support member 4 while also increasing the contact area with the outer flange 31, enhancing support stability. Multiple support members 4 are spaced apart along the circumference of the opening. After the inner pot 3 is placed, the multiple support members 4 together support the outer flange 31 at the rear side of the pot body 1, further stabilizing the inner pot 3 and ensuring it remains horizontal. When the pressure inside the pot exceeds the set safety pressure, the multiple support members 4 move downward, creating a larger opening at the rear side of the pressure cooker, allowing the gas inside the pot to quickly escape and release pressure.

[0066] Preferably, if Figure 1 As shown, the pot body 1 is provided with a support platform 15 at the opening and closing end 11 . When there is no pressure in the pot, the support surface of the support platform 15 is flush with the upper edge of the support member 4 .

[0067] In the unpressed state, when the inner pot 3 is placed in the pot body 1, the front outer flange 31 rests on the support platform 15, and the rear outer flange 31 rests on the support member 4, so that the inner pot 3 is in a horizontal posture as a whole, thereby ensuring that the sealing member 21 is stably in contact with the outer flange 31 all around the circumference, forming a good seal.

[0068] As the air pressure in the pot becomes higher and higher, the outer flange 31 on the rear side gradually presses the support member 4 downward, thereby causing the inner pot 3 to tilt. When the set safety pressure is exceeded, the rear seal 21 and the outer flange 31 are loosened to exhaust. When the air pressure returns to below the safety pressure, the support member 4 pushes the outer flange 31 upward and resets, and the rear seal 21 and the outer flange 31 are sealed again, and cooking continues.

[0069] It should be noted that the pressure cooking appliance of the present invention can be a high-pressure cooking appliance, such as a pressure cooker, or a micro-pressure cooking appliance, such as a micro-pressure rice cooker, as long as it can cook in an environment higher than atmospheric pressure.
