Description
Technical Field
[0001] The utility model relates to the technical field of cooking appliances, in particular to an anti-blocking cover assembly and a cooking appliance. Background Art
[0002] Currently, the design of the anti-blocking cover assembly in the electric pressure cooker market generally relies on the cooperation of an elastic chuck and a fixed cover to complete the installation and fixation of the anti-blocking cover. The above overall structure has many installation parts, which brings inconvenience to the installation. At the same time, with continuous disassembly and cleaning by users, the traditional elastic chuck is prone to deformation, which may affect its fit with the fixed cover, resulting in the spontaneous detachment of the fixed cover or the inability to disassemble the fixed cover. This installation structure not only affects the performance of the electric pressure cooker but also brings serious use troubles to users.
[0003] For example, a "pressure limiting valve assembly and cooking appliance" disclosed in a Chinese patent document, with the publication number CN219962527U, includes a pressure limiting valve and an exhaust pipe. The lower end of the exhaust pipe extends into the cavity through the central hole; the open end of the fixed cover forms an outward-turned annular flange; the locking member is located in the cavity of the fixed cover, and the locking member is used to lock the exhaust pipe; the anti-blocking cover is arranged around the outside of the fixed cover, and the anti-blocking cover is provided with air inlet holes; at least one elastic buckle is also formed on the anti-blocking cover, and the elastic buckle is buckled and connected with the annular flange of the fixed cover. This solution fixes the anti-blocking cover by setting an elastic buckle in cooperation with the fixed cover. However, when users continuously clean and disassemble, it affects its fit with the fixed cover, causing it to loosen or unable to separate from the elastic buckle, thus leading to potential safety hazards and inconvenience to users, and this solution has a high cost. Summary of the Utility Model
[0004] The utility model mainly solves the problem that the anti-blocking cover installation structure adopted by existing cooking appliances has low integration, resulting in inconvenient installation and disassembly of the anti-blocking cover. In response to this, the utility model provides an improved anti-blocking cover assembly and cooking appliance, integrating the exhaust pipe connecting piece into the fixed cover assembly to form an integrated structure. When using a cooking appliance integrated with the anti-blocking cover assembly, the user only needs to complete the connection between the anti-blocking cover assembly and the tail end of the exhaust pipe when installing the anti-blocking cover assembly. The improved solution significantly reduces the installation difficulty and improves the safety during use.

[0028] The technical solutions of the present invention will be further specifically described below through embodiments and in conjunction with the drawings.
[0029] Embodiment 1:
[0030] Please refer to Figures 1 to 5In order to solve the problem that the anti-blocking cover installation structure used in the existing cooking utensils has a low integration degree, which leads to the inconvenience of installing and removing the anti-blocking cover, the present embodiment provides an anti-blocking cover assembly 1, including an anti-blocking cover body 11 and a connector 12 embedded in the anti-blocking cover body 11. The connector 12 is provided with an exhaust pipe accommodating cavity 124 that can accommodate the tail end of the exhaust pipe 2, so that when the connector 12 and the anti-blocking cover body 11 are embedded into an integrated structure, they can be directly connected to the tail end of the exhaust pipe 2 through the exhaust pipe accommodating cavity 124, which greatly reduces the number of components that need to be manually connected when installing the anti-blocking cover assembly 11, significantly simplifies the installation steps, and reduces the difficulty of installation.
[0031] When the anti-blocking cover assembly is applied to a cooking utensil, the basic structure of the cooking utensil is first set, including a pot cover and a pot body, which are adapted and can be tightly connected. A through hole 3 is reserved on the pot cover, and the exhaust pipe 2 passes through the through hole 3 to connect the inside and outside spaces of the cooking utensil, so that when the internal air pressure increases, the gas can be discharged through the exhaust pipe 2. The anti-blocking cover assembly 1 is directly connected to the lower end of the exhaust pipe 2, which is located inside the cooking utensil and can prevent objects in the pot from blocking the bottom end of the exhaust pipe 2 when the air pressure increases. In addition, the upper end of the exhaust pipe 2 is covered by a pressure limiting valve 4, which is used to control the amount of gas transported from the inside of the cooking utensil to the exhaust pipe.
[0032] The anti-blocking cover component 1 has the following detailed design:
[0033] The anti-blocking cover assembly 1 is composed of a connector 12 and an anti-blocking cover body 11 adapted thereto, and the two are tightly combined to form an efficient and stable whole. As a key part of the connection, the connector has a special table 121 at one end, and the table 121 is fully adapted to the connector receiving window 111 set on the bottom surface of the anti-blocking cover body 11. The table 121 protrudes from the bottom surface of the connector 12, and the space formed by the table 121 and the bottom surface of the connector 12 is just snapped with the edge of the connector receiving window 111. By using interference fit or riveting at the connection, the connector 12 and the anti-blocking cover assembly 11 are tightly combined to form an integrated structure.
[0034] The other end of the connector 12 is open and hollow inside, and is specially provided with an exhaust pipe accommodating cavity 124, and a threaded area is provided on its inner wall, which is completely matched with the thread provided on the outer surface of the bottom end of the exhaust pipe 2. When installing, the anti-blocking cover assembly 1 can be stably installed on the tail end of the exhaust pipe 2 by directly rotating the anti-blocking cover assembly 1 through the thread. Such a design not only improves the stability of the connection between the anti-blocking cover assembly 1 and the exhaust pipe 2, but also facilitates the installation and removal process.
[0035] To achieve the effect of exhausting air from the inside of the cooking appliance to the outside, two crisscrossing and perpendicular ventilation grooves 122 are provided on the bottom surface of the connecting piece 12. The height of the ventilation grooves 122 in the vertical direction is greater than the bottom thickness of the anti-blocking cover main body 11. This enables the ventilation grooves 122 to be not only connected to the bottom end of the exhaust pipe 2 but also connected to the inside of the anti-blocking cover main body 11, achieving an excellent exhaust effect and optimizing the exhaust efficiency. In practical applications, multiple ventilation grooves 122 can be set as needed. A number of evenly distributed long strip-shaped air inlets 112 are also provided on the side surface of the anti-blocking cover main body 11 for connection with the exhaust pipe 2. These air inlets not only help to further disperse the air flow but also effectively prevent the occurrence of blockage phenomena.
[0036] In addition, the tabletop 121 not only undertakes the connection function but also enhances the overall aesthetics and practicality through a unique design. The design of the ventilation grooves 122 can not only prevent objects inside the cooking appliance from blocking the air outlet structure but also balance the pressure transmitted from the inside of the pot to the anti-blocking cover main body 11 and prevent its damage. In addition, a number of air holes are evenly provided around the connecting piece accommodation window 111 in the middle of the bottom surface of the anti-blocking cover main body, which can also play a role in quickly ventilating and balance the pressure received by the anti-blocking cover assembly 1.
[0037] During the operation of the cooking appliance, the internal temperature gradually rises, causing water vapor to accumulate inside the appliance, forming a high-temperature and high-pressure environment. The water vapor enters the exhaust pipe 2 along three routes respectively.
[0038] In the first route, the water vapor directly enters the exhaust pipe 2 through the inlet at the lower end of the exhaust pipe 2 along the ventilation groove 122 provided at the bottom of the connecting piece 12.
[0039] In the second route, the water vapor enters the ventilation groove 122 provided at the bottom of the connecting piece 12 along the air inlet 112 provided on the side wall of the anti-blocking cover main body 11, and after converging with the water vapor in the first route, they enter the exhaust pipe together.
[0040] In the third route, the water vapor converges into the ventilation groove 122 along the air holes provided at the bottom of the anti-blocking cover main body 11, and enters the exhaust pipe 2 together with the gas in the first and second routes.
[0041] The water vapor that enters the exhaust pipe 2 exerts pressure on the pressure limiting valve 4 covered at the top of the exhaust pipe 2 according to the pressure it carries. After reaching the pressure threshold that the pressure limiting valve 4 can withstand, the pressure limiting valve 4 is lifted by the water vapor and thus moves upward, enabling the gas to be discharged through the top of the exhaust pipe 2. When the pressure becomes small, the pressure limiting valve 4 falls back downward, forming a reciprocating motion until the pressure inside the cooking appliance is balanced and the pressure limiting valve 4 returns to its original position, and the exhaust stops.
[0042] Throughout the process, the exhaust pipe 2 is tightly connected to the anti-blocking cover assembly 1, without being deformed due to excessive pressure, and ensuring a stable connection between the exhaust pipe and the pot lid. Under high-pressure conditions, the connection method between the integrated anti-blocking cover assembly 1 and the bottom end of the exhaust pipe 2 can also effectively prevent the anti-blocking cover assembly 1 from loosening, ensuring the stable operation of the cooking device.
[0043] Embodiment 2:
[0044] Based on Embodiment 1, for the anti-blocking cover assembly and cooking appliance in this embodiment, the structure of the connecting member 12 in Embodiment 1 is further optimized to simplify the installation operation.
[0045] Referring to Figure 2 It can be known that in this embodiment, the connecting member 12 is uniformly provided with smooth inclined surfaces in the upper region of the threaded area along the opening of the exhaust pipe receiving cavity 124. And the inner diameter of the opening of the exhaust pipe receiving cavity 124 is larger than the inner diameter of the threaded area; thus, a downward inclined surface is formed, which enables the bottom end of the exhaust pipe 2 to be directly guided into the exhaust pipe receiving groove 124 by the acting force when the bottom end of the exhaust pipe 2 touches the edge of the inclined surface without the need to completely align the bottom end of the exhaust pipe 2 with the exhaust pipe receiving cavity 124 provided on the anti-blocking cover assembly 1, and complete the installation according to the set installation method.
[0046] This design significantly improves the accuracy of blind operation installation and provides convenience to users.
[0047] Embodiment 3:
[0048] The difference between the anti-blocking cover assembly and cooking appliance in this embodiment and Embodiment 1 is that the inner edge of the exhaust pipe receiving cavity 124 provided by the connecting member 12 in this embodiment is provided with bayonets, and a plurality of groups of buckles adapted to the bayonets are provided at the bottom end of the exhaust pipe 2, so that they are tightly connected by a snap-fit method. Since the number of bayonets and buckles is large enough, the pressure change inside the cooking appliance will only have a slight impact on it, and it is not enough to cause deformation between all the buckles and bayonets, ensuring that the anti-blocking cover assembly 1 will not fall off during the working state. A plurality of grooves are provided on the outer surface of the side wall of the connecting member 12, which can weaken the acting force of the airflow on its surface and extend the service life of the connecting member 2.
[0049] In addition, during the installation process, only the anti-blocking cover assembly 1 needs to be aligned with the lower end of the exhaust pipe 2, and after fitting and clamping, the installation can be completed. This design significantly reduces the installation difficulty.
[0050] It should be understood that the embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
