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 include pressure cookers, micro-pressure rice cookers, and other devices. The lids of some pressure cooking appliances are pivotally connected to the pot body via a shaft, torsion spring, or other structure, allowing the lid to be flipped up and down relative to the pot body for opening and closing. During the pressure cooking process, because the air pressure inside the pot is higher than the external atmospheric pressure, the gas inside the pot exerts an upward force on the lid. However, the movement of the lid is restricted by the shaft and other structures, so the force is concentrated more at the pivoting connection between the lid and the pot body, increasing the risk of damage to the connection.

[0003] Typically, the pot body is provided with a connecting seat for rotationally connecting to the pot lid. When the pot lid is pushed upward by the air pressure in the pot, the hinged seat is given an outward extrusion force and a vertical force, so the outer side and the lower side of the connecting seat become areas with relatively weak strength.

[0004] Although some existing pressure cooking appliances include reinforcement plates and other structures at the connection base, these reinforcement structures are dispersed, supporting different areas of the connection base. The multiple reinforcement structures are unconnected, resulting in a single reinforcement structure bearing the load when the connection base is subjected to force. This still presents the problem of excessive force on the connection base and the reinforcement structures. Furthermore, although the reinforcement structure below the connection base is located at the rear end of the pot body to provide support, the structural and spatial limitations of the rear end of the pot body force the bottom reinforcement structures to either side of the connection base, effectively avoiding the area where the connection base is located. This arrangement does not effectively support the connection base, resulting in poor support from the bottom of the connection base, making it susceptible to deformation or damage when subjected to vertical forces. Utility Model Content

[0005] The utility model provides a pressure cooking appliance to solve the problems that the reinforcement structure at the connecting seat is relatively dispersed, the connecting seat cannot disperse the force well when subjected to force, the single reinforcement structure is subjected to concentrated force and is easy to be damaged, and the reinforcement structure below the connecting seat cannot effectively support the bottom of the connecting seat.

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

[0007] A pressure cooking appliance comprises a pot body and a lid, one end of the lid being hinged to the pot body, the pot body comprising an outer cover and a middle ring located above the outer cover, the middle ring having a panel, an upwardly protruding connecting wall being provided on one side of the top surface of the panel, the connecting wall forming an installation space for installing a hinged structure, the pressure cooking appliance further comprising a reinforcing bracket and a reinforcing member fixedly connected to the reinforcing bracket, at least a portion of the reinforcing bracket being located within the installation space to support the connecting wall from the side, the reinforcing member being located below the panel to support the panel from the bottom, the reinforcing member covering at least the area where the connecting wall is located in the circumferential direction of the panel.

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

[0009] The reinforcing bracket includes a first reinforcing part and a second reinforcing part. The first reinforcing part is located in the installation space and contacts the outer side surface of the connecting wall. The second reinforcing part is located below the panel and contacts the bottom surface of the panel. The reinforcing member is located below the second reinforcing part and contacts the bottom surface of the second reinforcing part.

[0010] The first reinforcement part contacts the outer side surface of the connecting wall through a first contact plane, the second reinforcement part contacts the bottom surface of the panel through a second contact plane, and the reinforcement member contacts the bottom surface of the second reinforcement part through a third contact plane.

[0011] The lower edge of the first reinforcing portion is lower than the lower edge of the second reinforcing portion, so that the first reinforcing portion and the second reinforcing portion form an accommodating space for accommodating the reinforcement member.

[0012] The connecting wall includes a fixed wall and installation walls located on both sides of the fixed wall. There is an angle between the installation wall and the fixed wall so that the fixed wall and the installation wall cooperate to form an installation space. The installation wall is provided with an installation position for installing the rotating shaft, and the strengthening bracket is in contact with the outer side surface of the fixed wall.

[0013] The top of the fixed wall is provided with a shielding flange bent toward the installation space.

[0014] The reinforcing bracket is provided with an installation opening for the rotating shaft to pass through.

[0015] The reinforcement member and the reinforcement bracket are integrally formed; or,

[0016] The reinforcing bracket is provided with a bent fixed rib, the reinforcing piece is provided with a reinforcing flange, both the fixed rib and the reinforcing flange are provided with fixing holes, and the pressure cooking appliance also includes a fastener, which passes through the fixing hole to fasten the fixed rib and the reinforcing flange.

[0017] The panel is provided with a through opening for placing the inner liner, and the outer edge of the panel has a first extension section and a second extension section along the circumferential direction, a first area is provided between the first extension section and the edge of the through opening, and a second area is provided between the second extension section and the edge of the through opening, the width of the first area is greater than the width of the second area, and the reinforcement extends along the circumference of the panel to have a first reinforcement area corresponding to the installation space, and a second reinforcement area located within the first area.

[0018] The panel has a center line, which divides the panel into a rear area and a front area. The connecting wall is located in the rear area, and the reinforcement is arranged in the rear area.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0020] 1. In the present invention, the reinforcing bracket is located in the installation space enclosed by the connecting wall, in contact with the outer side of the connecting wall, and is used to resist the outward deformation of the connecting wall and bear the outward extrusion force of the connecting wall. The reinforcing member is located below the connecting wall and in contact with the lower area of ​​the connecting wall, and is used to resist the vertical deformation of the connecting wall and bear the vertical extrusion force of the connecting wall. The reinforcing bracket and the reinforcing member are fixedly connected so that the two are associated. When one of them is subjected to force, the force can be transferred to the other through the connection, so that the reinforcing bracket and the reinforcing member jointly bear the extrusion force from the connecting wall, making the force more dispersed, alleviating the force on a single component, improving the structural reinforcement effect, and reducing the risk of deformation or damage of the reinforcing member or the reinforcing bracket.

[0021] In addition, the reinforcement is located below the connecting wall, covering the area on the panel corresponding to the connecting wall, so that the reinforcement can directly support the panel area where the connecting wall is located, and then jointly support the outer side and bottom of the connecting wall, effectively ensuring the structural stability of the middle ring hinge, that is, the connecting wall, under high-pressure environment.

[0022] 2. As a preferred embodiment of the present invention, the first reinforcement portion and the outer side surface of the connecting wall are in contact through a first contact plane, the second reinforcement portion and the bottom surface of the panel are in contact through a second contact plane, and the reinforcement member and the bottom surface of the second reinforcement portion are in contact through a third contact plane. Plane contact is adopted between the reinforcement bracket and the connecting wall, and between the reinforcement member and the reinforcement bracket. On the one hand, it can improve the contact stability, increase the force-bearing area, make the force more dispersed on the plane, and reduce local force. On the other hand, it is more conducive to the transmission of force and reduces the possibility of local deformation of the reinforcement member and the reinforcement bracket. Specifically, the reinforcement bracket provides support for the connecting wall in the horizontal outward direction through vertical plane contact; the second reinforcement portion and the panel area where the connecting wall is located are in horizontal plane contact, providing support in the vertical direction. The reinforcement member is located below the second reinforcement portion and is in horizontal plane contact.

[0023] 3. As a preferred embodiment of the present invention, the connecting wall includes a fixed wall and mounting walls located on both sides of the fixed wall, an angle is formed between the mounting wall and the fixed wall so that the fixed wall and the mounting wall cooperate to form an installation space, the mounting wall is provided with a mounting position for installing a rotating shaft, and the reinforcing bracket contacts the outer side surface of the fixed wall. The fixed wall and the mounting wall cooperate to form an installation space, wherein the mounting wall is used to install the rotating shaft, and the area of ​​the outer side surface (the side facing away from the center of the pot body) is relatively small, while the outer side surface of the fixed wall can be designed as a large-area planar structure. Therefore, the reinforcing bracket is in contact with the fixed wall. On the one hand, part of the structure of the reinforcing bracket can be accommodated in the installation space, thereby saving space and making the structure more compact. On the other hand, the reinforcing bracket can be in contact with the fixed wall through a large-area plane, thereby improving the contact effect and support effect.

[0024] 4. As a preferred embodiment of the present invention, the reinforcing bracket is provided with an installation opening for the shaft to pass through. The shaft cooperates with the reinforcing bracket to position the reinforcing bracket according to the location of the shaft. After the shaft is installed, the reinforcing bracket can limit the shaft and connect the shaft and the reinforcing bracket, improving structural stability while allowing the shaft to directly transmit force to the reinforcing bracket, allowing the reinforcing bracket to support the shaft and enhance the structural reinforcement effect at the shaft.

[0025] 5. As a preferred embodiment of the present invention, the panel is provided with a through opening for placing the inner pot, and the outer edge of the panel has a first extension section and a second extension section along the circumference. A first region is defined between the first extension section and the edge of the through opening, and a second region is defined between the second extension section and the edge of the through opening. The width of the first region is greater than the width of the second region. The reinforcement extends along the circumference of the panel to provide a first reinforcement region corresponding to the installation space, and a second reinforcement region located within the first region. The connecting wall is located within the second region, and the reinforcement extends to both sides from the location of the connecting wall so that the first reinforcement region is located below the installation space within the second region. The second reinforcement region corresponds to the first region. Since the width of the first region is relatively large and the panel is a plate-like structure, the strength of the first region is relatively low. Therefore, the reinforcement can not only specifically improve the strength of the connecting wall, but also greatly improve the structural strength of the first region, i.e., the rear end of the pot body, making the rear end of the pot body as a whole less susceptible to deformation or damage, thereby improving the overall strength of the panel.

[0045] like Figure 1 、 Figure 8As shown, a pressure cooking appliance includes a pot body and a pot cover 2, one end of the pot cover 2 is hinged to the pot body, the pot body includes an outer cover and a middle ring 1 located above the outer cover, the middle ring 1 has a panel 11, and an upwardly protruding connecting wall 12 is provided on one side of the top surface of the panel 11, and the connecting wall 12 forms an installation space 124 for installing a hinge structure. The pressure cooking appliance also includes a reinforcing bracket 3 and a reinforcing member 4 fixedly connected to the reinforcing bracket 3, at least a portion of the reinforcing bracket 3 is located in the installation space 124 to support the connecting wall 12 from the side, the reinforcing member 4 is located below the panel 11 to support the panel 11 from the bottom, and the reinforcing member 4 covers at least the area where the connecting wall 12 is located in the circumferential direction of the panel 11.

[0046] In the present invention, the reinforcing bracket 3 is located in the installation space 124 surrounded by the connecting wall 12, and is in contact with the outer side of the connecting wall 12, and is used to resist the outward deformation of the connecting wall 12 and bear the outward extrusion force of the connecting wall 12. The reinforcing member 4 is located below the connecting wall 12, and is in contact with the lower area of ​​the connecting wall 12, and is used to resist the vertical deformation of the connecting wall 12 and bear the vertical extrusion force of the connecting wall 12. The reinforcing bracket 3 and the reinforcing member 4 are fixedly connected so that the two are associated. When one of them is subjected to force, the force can be transferred to the other through the connection, so that the reinforcing bracket 3 and the reinforcing member 4 jointly bear the extrusion force from the connecting wall 12, making the force more dispersed, alleviating the force on a single component, improving the structural reinforcement effect, and reducing the risk of deformation or damage of the reinforcing member 4 or the reinforcing bracket 3.

[0047] In addition, the reinforcement 4 is located below the connecting wall 12, covering the area on the panel 11 corresponding to the connecting wall 12, so that the reinforcement 4 can directly support the area of ​​the panel 11 where the connecting wall 12 is located, and then jointly support the outer side and bottom of the connecting wall 12, effectively ensuring the structural stability of the hinge of the middle ring 1, that is, the connecting wall 12, under high-pressure environment.

[0048] It can be understood that the reinforcement wall is provided on the upper side of the panel 11, and the reinforcement member 4 is located on the lower side of the panel 11. The reinforcement member 4 covers the area where the connecting wall 12 is located in the circumferential direction of the panel 11, such as Figure 8 As shown, the arc segment occupied by the connecting wall 12 along the circumference of the panel 11 and the arc segment occupied by the reinforcing member 4 extending along the circumference of the panel 11 overlap in the radial direction of the pot body, so that the reinforcing member 4 directly supports the area on the panel 11 corresponding to the connecting wall 12. However, the reinforcing member 4 can be arranged above and below the connecting wall 12, or as shown in FIG. Figure 4 As shown, the upper and lower positions are offset.

[0049] As a preferred embodiment of the present invention, Figure 2As shown, the reinforcing bracket 3 includes a first reinforcing portion 31 and a second reinforcing portion 32. The first reinforcing portion 31 is located in the installation space 124 and contacts the outer side surface of the connecting wall 12. The second reinforcing portion 32 is located below the panel 11 and contacts the bottom surface of the panel 11. The reinforcing member 4 is located below the second reinforcing portion 32 and contacts the bottom surface of the second reinforcing portion 32.

[0050] Specifically, such as Figure 2 、 Figure 3 、 Figure 6 As shown, the reinforcing bracket 3 is an L-shaped structure, wherein the first reinforcing portion 31 is located on the outside of the connecting wall 12, and the second reinforcing portion 32 is located on the lower side of the panel 11. The first reinforcing portion 31 and the second reinforcing portion 32 can be formed as one piece or separately, and connected as one piece by welding, screws, etc.

[0051] The reinforcement member 4 is located below the second reinforcement portion 32 , so that the second reinforcement portion 32 and the reinforcement member 4 jointly support the bottom of the connecting wall 12 , thereby improving the supporting effect and structural reinforcement effect of the connecting wall 12 .

[0052] Preferably, if Figure 2 As shown, the first reinforcement portion 31 and the outer side surface of the connecting wall 12 contact through a first contact plane 314, the second reinforcement portion 32 and the bottom surface of the panel 11 contact through a second contact plane 321, and the reinforcement member 4 contacts the bottom surface of the second reinforcement portion 32 through a third contact plane 322.

[0053] Planar contact is adopted between the reinforcing bracket 3 and the connecting wall 12, and between the reinforcing member 4 and the reinforcing bracket 3. On the one hand, this can improve contact stability, increase the force-bearing area, and make the force more dispersed on the plane, reducing local force. On the other hand, it is more conducive to the transmission of force and reduces the possibility of local deformation of the reinforcing member 4 and the reinforcing bracket 3. Specifically, the reinforcing bracket 3 provides support for the connecting wall 12 in the horizontal outward direction through vertical plane contact; the second reinforcing portion 32 and the panel 11 area where the connecting wall 12 is located are in horizontal plane contact, providing support in the vertical direction. The reinforcing member 4 is located below the second reinforcing portion 32 and is in horizontal plane contact.

[0054] Preferably, if Figure 6 、 Figure 7 As shown, the first reinforcement portion 31 and the second reinforcement portion 32 are both plate-shaped structures, and the reinforcement member 4 is also a plate-shaped structure, so as to have a larger contact surface area when in contact, thereby improving the supporting effect.

[0055] Specifically, such as Figure 2 、 Figure 6As shown, the first reinforcement portion 31 includes a rear wall 311 and mating walls 312 located on both sides of the rear wall 311 and protruding toward the center of the pot body. The mating walls 312 are provided with installation openings 313 for installing the rotating shaft 5. The mating walls 312 abut and support the outer side surface of the connecting wall 12. The rotating shaft 5 cooperates with the reinforcing bracket 3, thereby positioning the reinforcing bracket 3 according to the position of the rotating shaft 5. After the rotating shaft 5 is installed, the reinforcing bracket 3 can limit the rotating shaft 5 and associate the rotating shaft 5 with the reinforcing bracket 3. While improving structural stability, it also allows the rotating shaft 5 to directly transmit the force to the reinforcing bracket 3, so that the reinforcing bracket 3 supports the rotating shaft 5 and improves the structural reinforcement effect at the rotating shaft 5.

[0056] Specifically, such as Figure 6 As shown, the installation opening 313 extends to the edge of the matching wall 312 to form a mounting groove, so that the rotating shaft 5 can enter the installation opening 313 through the groove, reducing the difficulty of installing the rotating shaft 5 and improving assembly efficiency.

[0057] like Figure 2 As shown, the lower edge of the first reinforcement portion 31 is lower than the lower edge of the second reinforcement portion 32 , so that the first reinforcement portion 31 and the second reinforcement portion 32 enclose an accommodating space 34 for accommodating the reinforcement member 4 .

[0058] The reinforcement member 4 is fixed within the accommodation space 34 between the first reinforcement portion 31 and the second reinforcement portion 32. This not only facilitates the installation and positioning of the reinforcement member 4, but also reduces the overall volume of the reinforcement member 4 and the reinforcement bracket 3, making the entire reinforcement structure more compact and saving space in the pot body. Furthermore, the first reinforcement portion 31 can also shield part of the reinforcement member 4 from the outside, making the entire reinforcement structure more concise and easier for assembly personnel.

[0059] It should be noted that the present invention does not limit the structure of the connecting wall 12. In one embodiment, the connecting wall 12 protrudes from the panel 11 to form a boss structure. All surfaces of the boss structure are closed, and openings for installing the rotating shaft 5 are opened on the two opposite side walls.

[0060] In another preferred embodiment, Figure 3 As shown, the connecting wall 12 includes a fixed wall 121 and mounting walls 122 located on both sides of the fixed wall 121. There is an angle between the mounting wall 122 and the fixed wall 121 so that the fixed wall 121 and the mounting wall 122 cooperate to form an installation space 124. The mounting wall 122 is provided with a mounting position 1221 for installing the rotating shaft 5, and the reinforcing bracket 3 is in contact with the outer side surface of the fixed wall 121.

[0061] In this embodiment, the connecting wall 12 only has a fixed wall 121 close to the center of the pot body, and installation walls 122 on both sides of the fixed wall 121, and does not have an outer wall on the side of the center of the pot body. Therefore, the installation space 124 is an open area, so that part of the area of ​​the reinforcing bracket 3 can be accommodated in the installation area to reduce the space occupied by the installation bracket.

[0062] The fixed wall 121 and the mounting wall 122 cooperate to form an installation space 124, wherein the mounting wall 122 is used to install the rotating shaft 5, and the area of ​​the outer side surface (the side away from the center of the pot body) is smaller, and the outer side surface of the fixed wall 121 can be designed as a large-area planar structure. Therefore, the reinforcing bracket 3 is in contact with the fixed wall 121. On the one hand, part of the structure of the reinforcing bracket 3 can be accommodated in the installation space 124, thereby saving space and making the structure more compact. On the other hand, the reinforcing bracket 3 can be in contact with the fixed wall 121 through a large-area plane, thereby improving the contact effect and support effect.

[0063] Specifically, the matching wall 312 of the first reinforcement portion 31 is located between the two mounting walls 122 . A torsion spring is further provided at the rotating shaft 5 , and the torsion spring is located between the two matching walls 312 .

[0064] Further, if Figure 2 、 Figure 3 As shown, a shielding flange 123 bent toward the installation space 124 is provided on the top of the fixing wall 121 .

[0065] The shielding flange 123 can cooperate with the top of the reinforcing bracket 3 to serve as the installation position of the reinforcing bracket 3, thereby reducing the difficulty of installing the reinforcing bracket 3. At the same time, when the pot lid 2 is flipped open, the shielding flange 123 can also block liquid dripping from the inner surface of the pot lid 2, preventing the liquid from flowing into the installation space 124, thereby ensuring the cleanliness of the installation space 124.

[0066] It should be noted that the present invention does not limit the assembly method of the reinforcing bracket 3 and the reinforcing member 4. In a preferred embodiment, the reinforcing member 4 is integrally formed with the reinforcing bracket 3. This eliminates the need for assembly and improves the strength of the connection between the two, allowing the two to function as a whole to bear the force of the connecting wall 12, thereby enhancing the structural reinforcement effect.

[0067] In another preferred embodiment, the reinforcement member 4 and the reinforcement bracket 3 are separate structures and are assembled into one by welding, screw connection, etc.

[0068] Specifically, in one embodiment, Figure 4 、 Figure 5 、 Figure 6 、 Figure 7As shown, the reinforcing bracket 3 is provided with a bent fixed rib 33, the reinforcing member 4 is provided with a reinforcing flange 42, and both the fixed rib 33 and the reinforcing flange 42 are provided with fixing holes. The pressure cooking appliance also includes a fastener, which passes through the fixing hole to fasten the fixed rib 33 and the reinforcing flange 42.

[0069] Specifically, a fixed rib 33 bent upward is provided at the bottom of the reinforcing bracket 3, and the reinforcing member 4 has a contact wall 41 that abuts against the bottom of the reinforcing bracket 3 or the panel 11. The edge of the contact wall 41 is provided with a reinforcing flange 42 folded downward. The fastener passes through the fixed rib 33 and the reinforcing flange 42 in sequence from the outside to the inside, fastening the two together so that the operation of the fastener is located on the outside, reducing the difficulty of operation.

[0070] At the same time, the reinforcing flange 42 also increases the strength of the contact wall 41 , thereby increasing the overall strength of the reinforcement 4 and the supporting effect on the panel 11 .

[0071] Preferably, if Figure 8 As shown, the panel 11 is provided with a through opening for placing the inner liner, and the outer edge of the panel 11 has a first extension section and a second extension section along the circumferential direction, a first area 112 is provided between the first extension section and the edge of the through opening, and a second area 111 is provided between the second extension section and the edge of the through opening, the width of the first area 112 is greater than the width of the second area 111, and the reinforcement 4 extends along the circumference of the panel 11 to have a first reinforcement area 43 corresponding to the installation space 124, and a second reinforcement area 44 located in the first area 112.

[0072] It can be understood that the curvature of the first extension section is greater than the curvature of the second extension section, so that the cross section of the pot body is a runway circle, the first area 112 is located at the four corners of the pot body cross section, and the second area 111 is located at the front, back, left and right ends of the pot body cross section.

[0073] Connecting wall 12 is located within second region 111. Reinforcement member 4 extends from connecting wall 12 to both sides, so that first reinforcement region 43 is located below mounting space 124 within second region 111. Second reinforcement region 44 corresponds to first region 112. Due to the greater width of first region 112 and the plate-like structure of panel 11, first region 112 has relatively low strength. Therefore, reinforcement member 4 not only effectively improves the strength of connecting wall 12 but also significantly enhances the structural strength of first region 112, i.e., the rear end of the pot body, making the rear end of the pot body less susceptible to deformation or damage, thereby improving the overall strength of panel 11.

[0074] The panel 11 has a center line, which divides the panel 11 into a rear area 14 and a front area 13 . The connecting wall 12 is located in the rear area 14 , and the reinforcement 4 is provided in the rear area 14 .

[0075] Since the connecting wall 12 is located in the rear area 14, the pot cover 2 and the pot body are connected in the rear area 14, and the front area 13 is correspondingly provided with a snap-fit ​​structure of the pot cover 2 and the pot body. When pressure is applied to the pot, the rear area 14, especially the connecting wall 12, is subjected to a relatively large force. The reinforcement 4 is arranged here, which can not only effectively improve the overall strength of the connecting wall 12 and the rear area 14, and prevent the rear part of the panel 11 from being deformed or damaged, but also avoid the snap-fit ​​structure of the front area 13, prevent the snap-fit ​​structure from interfering with the reinforcement 4, and reduce the material used for the reinforcement 4, thereby saving costs and reducing the overall weight of the panel 11, making the whole machine lighter.

[0076] Specifically, such as Figure 8 As shown, the reinforcement 4 extends from the connecting wall 12 at the rear end of the panel 11 to both sides to the first area 112 .

[0077] 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.
