Description

Technical Field

[0001] This utility model relates to the field of pressure cooker technology, and in particular to a dual-purpose pressure cooker. Background Technology

[0002] To address the issue of pressure cookers being unusable during power outages, existing technology has developed dual-purpose pressure cookers. These cookers support both electric heating and open flame heating. In the event of a power outage, users can remove the inner pot and heat it over an open flame, thus switching between cooking methods.

[0003] However, in existing dual-purpose pressure cookers, the lid cannot be properly fixed to the inner pot, making it difficult for the inner pot to perform high-pressure cooking under open flame.

[0004] For example, the patent disclosed in CN213664808U discloses a dual-purpose pressure cooker. The lid is fixedly connected to the pressure cooker body by a buckle, but the lid itself lacks a fixed connection structure with the inner pot, which makes it impossible to complete the high-pressure cooking work well when the inner pot is switched to open flame cooking. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a dual-purpose pressure cooker, in which the lid can be stably connected to the inner pot, so that high-pressure cooking can be completed well whether in open flame heating or electric heating mode.

[0006] The technical solution adopted by this utility model to solve the problem is: a dual-purpose pressure cooker, including a main body, the main body including an inner pot and a lid, the upper end of the inner pot being provided with a first flange; a locking member is movably installed on the outer periphery of the lid, the locking member being able to move radially toward the central axis of the lid, the upper end of the locking member being engaged with the upper side of the lid, and the lower end of the locking member being provided with a second flange; the main body has a locked state and an unlocked state; when the main body is in the locked state, the locking member is close to the central axis, and the second flange is engaged below the first flange.

[0007] As a further improvement to the above technical solution, the upper edge of the pot lid is provided with an annular portion, and the upper end of the locking member is provided with a third flange, which is above the annular portion.

[0008] As a further improvement to the above technical solution, a sealing ring is installed on the lower surface of the annular portion. When the main body is in a locked state, the sealing ring is pressed between the annular portion and the first flange.

[0009] As a further improvement to the above technical solution, the outer edge of the annular portion extends downward with an extension portion, which overlaps the outer periphery of the first flange when the main body is in a locked state.

[0010] As a further improvement to the above technical solution, the lower end of the extension is inclined outward to form a guide portion.

[0011] As a further improvement to the above technical solution, a knob is installed on the pot lid, and a transmission component is installed inside the pot lid. The first end of the transmission component is connected to the knob, and the second end of the transmission component is fixedly connected to the locking component.

[0012] As a further improvement to the above technical solution, the number of locking components is two and they are arranged opposite to each other on both sides of the pot lid. The number of transmission components is two and they are located on the same diameter of the pot lid. The two transmission components are either far apart or close to each other on this diameter. The knob is installed at the center of the pot lid. The lower end of the knob is provided with two oppositely arranged pins. The first end is provided with a pin hole. The pin is rotatably connected in the pin hole. The front-to-back dimension of the pin hole is larger than the diameter of the pin. When the knob is rotated, the two transmission components can drive the two locking components to move radially toward the central axis.

[0013] As a further improvement to the above technical solution, the pot lid is provided with a straight guide groove, and the transmission component is installed in the straight guide groove.

[0014] As a further improvement to the above technical solution, a decorative panel is fixedly installed on the pot lid, and the decorative panel covers the straight guide groove.

[0015] As a further improvement to the above technical solution, handles are fixedly connected to both sides of the inner liner.

[0016] The beneficial effects of this utility model are as follows: By installing a locking component on the outer periphery of the pot lid, the locking component can move radially toward the central axis of the pot lid. Moving the locking component causes the second flange at the lower end of the locking component to engage with the lower part of the first flange of the inner pot, thereby fixing the pot lid to the inner pot and improving the connection stability between the pot lid and the inner pot. This allows for better high-pressure cooking regardless of whether it is under open flame heating or electric heating. Attached Figure Description

[0029] Reference Figures 1 to 6 A dual-purpose pressure cooker includes a main body, which comprises an inner pot 1 and a lid 2. The upper edge of the inner pot 1 is folded outward to form a first flange 11. A locking member 26 is movably mounted on the outer periphery of the lid 2. The locking member 26 is relatively fixed to the lid 2 and can move radially toward the central axis 20 of the lid 2 (i.e., it can move closer to or away from the central axis 20 along the radius of the lid 2). The upper end of the locking member 26 is engaged with the upper surface of the lid 2, and the lower end of the locking member 26 is provided with a second flange 261. Figure 5 and Figure 6 As shown, the main body (inner pot 1 and lid 2) has a locked state and an unlocked state. When the main body is in the locked state, the locking member 26 is close to the central axis 20, and the second flange 261 is engaged below the first flange 11. When the main body is in the unlocked state, the locking member 26 is away from the central axis 20, the second flange 261 is away from and releases the first flange 11, and the inner pot 1 can detach from the lid 2 from below. The locking member 26 fixes the inner pot 1 and the lid 2 together, improving the connection stability between the lid 2 and the inner pot 1. The lid 2 is directly fixed to the inner pot 1, so that the pressure cooker's high-pressure cooking work is not affected whether it is heated by open flame or electric heating, allowing the pressure cooker to complete the high-pressure cooking work well.

[0030] In some embodiments, the upper edge of the pot lid 2 is provided with an annular portion 21, and the upper end of the locking member 26 is provided with a third flange 262. The third flange 262 abuts against the upper surface of the annular portion 21. The annular portion 21 restricts the degree of freedom of the third flange 262 in the vertical direction. When the locking member 26 moves radially, the third flange 262 can slide horizontally on the upper surface of the annular portion 21.

[0031] Specifically, the longitudinal section of the locking member 26 is U-shaped.

[0032] In a preferred embodiment, a sealing ring 27 is installed on the lower surface of the annular portion 21. When the main body is in a locked state, the sealing ring 27 is pressed between the annular portion 21 and the first flange 11, thereby improving the connection and sealing between the inner liner 1 and the lid 2.

[0033] In a preferred embodiment, the outer edge of the annular portion 21 extends downward to form an extension portion 28. When the main body is in a locked state, the extension portion 28 abuts against the outer periphery of the first flange 11, further improving the connection stability between the inner liner 1 and the lid 2.

[0034] In a preferred embodiment, the lower end of the extension 28 is inclined outward to form a guide 29. By providing the guide 29, the inner pot 1 can slide into the pot lid 2 along the guide 29.

[0035] In a preferred embodiment, a knob 24 is installed on the pot lid 2, and a transmission component 25 is installed inside the pot lid 2. The first end (inner end) of the transmission component 25 is connected to the knob 24, and the second end of the transmission component 25 is fixedly connected to the locking component 26. By rotating the knob 24, the knob 24 drives the transmission component 25, and the transmission component 25 and the locking component 26 move synchronously, thereby realizing the radial movement of the locking component 26.

[0036] In a preferred embodiment, such as Figure 3 As shown, the locking member 26 has an arc-shaped structure, and there are two locking members 26 arranged opposite each other on both sides of the pot lid 2 (the left and right sides in the figure). There are two transmission members 25 located on the same diameter of the pot lid 2, and the two transmission members 25 are either far apart or close to each other on this diameter. The knob 24 is installed at the center of the pot lid 2, and the lower end of the knob 24 is provided with two oppositely arranged pins 241. The first end is provided with a pin hole 251, and the pin 241 is rotatably connected in the pin hole 251. Figure 4 As shown, the front-to-back dimension of the pin hole 251 is larger than the diameter of the pin 241. When the pin 241 is inserted into the pin hole 251, there is a clearance between the front and back sides of the pin 241 and the pin hole 251. The clearance is used to avoid the arc-shaped trajectory of the pin 241 in the front-to-back direction, so that the pin 241 can drive the transmission component 25 to move linearly in diameter. When the knob 24 is rotated, the two transmission components 25 can drive the two locking components 26 to move radially toward the central axis 20.

[0037] In a preferred embodiment, the pot lid 2 is provided with a straight guide groove 22, which is located on the aforementioned diameter. The transmission member 25 is installed in the straight guide groove 22, thereby restricting the rotation of the transmission member 25 and enabling the transmission member 25 to better convert the rotational movement of the knob 24 into the linear movement of the transmission member 25.

[0038] Specifically, in a preferred embodiment, the lower end of the knob 24 is rotatably connected to a straight plate 242, which is arranged in the left-right direction (located on the aforementioned diameter). The first ends of the two transmission components 25 are provided with straight holes 252, and the two straight holes 252 form a shape that fits the straight plate 242. The two transmission components 25 are installed on both sides of the straight plate 242, and the straight plate 242 further restricts the linear movement of the transmission components 25.

[0039] In a preferred embodiment, a decorative panel 23 is fixedly installed on the pot lid 2, and the decorative panel 23 covers the straight guide groove 22 and conceals the transmission component 25.

[0040] In some embodiments, handles 12 are fixedly connected to both sides of the inner liner 1.

[0041] In a preferred embodiment, the pot body 3 is also included, and handle grooves 31 are provided at both ends of the pot body 3. When the main body is in an electric heating state, the inner pot 1 is inserted into the pot body 3, and the handle 12 is inserted into the handle groove 31.

[0042] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the inventive concept of this utility model, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
