Description

Technical Field

[0001] This invention relates to the field of cooking appliances, and more specifically, to an electric pressure cooker with a cooling function. Background Technology

[0002] Electric pressure cookers have become an indispensable cooking appliance in our kitchens due to their many advantages, such as fast cooking, high cooking temperature, and good food taste. However, the problem that plagues the entire industry is that after the electric pressure cooker finishes cooking, users cannot open the lid immediately because of the high pressure inside the pot. Instead, they must open the pressure relief valve to release the pressure or let the food inside the pot cool naturally until the pressure inside the pot decreases before they can open the lid and take out the food. This makes it inconvenient and slow to use.

[0003] Currently, there are also products that use water cooling to accelerate cooling, such as the method proposed in patent CN100469288C, in which cooling water can be injected into the top of the pressure cooker. After the cooling water fills the top concave surface of the locking lid, it spreads evenly down the top surface and flows into the drain trough, and is discharged through the water collection box and drain pipe, so that the pressure inside the pot is quickly cooled down.

[0004] Although it can achieve water cooling, it requires manual operation each time, which is quite troublesome and needs improvement. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an electric pressure cooker with a cooling function.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 5 As shown, a specific embodiment of the present invention discloses an electric pressure cooker with a cooling function, including a pot body 100 and a pot lid 200. The pot lid 200 includes a lid frame 210, a top cover 220, a lid body 230, and a handle 240. The lid body 230 is rotatably mounted on the bottom of the lid frame 210, the top cover 220 is fitted onto the top of the lid frame 210, and the handle 240 is mounted on the top of the lid frame 210 and protrudes from the top outer side of the top cover. The handle 240 is connected to the lid body 230 and is used to rotate and adjust the lid body 230 to achieve opening and closing. An exhaust valve 250 is installed on the lid body 230 for venting air. Figure 9As shown, the device includes a water supply mechanism 300, which comprises a water storage component 310, a gas supply hose 320, and a water supply hose 330. An exhaust pipe 260 is installed on the cover 230, and a first solenoid valve 261 is installed at the end of the exhaust pipe 260. One end of the gas supply hose 320 is connected to the first solenoid valve 261, and the other end is connected to the water storage component 310. A clamping cavity 400 is provided on the cover 230, and a water pipe 270 is connected to the clamping cavity 400. One end of the water supply hose 330 is connected to the water pipe 270, and the other end is connected to the water storage component 310. A piston 340 is provided inside the water storage component 310. After high-pressure operation is completed, the high-pressure gas inside the pot enters the water storage component, pushing the piston and causing the coolant inside the water storage component to enter the clamping cavity to cool the cover. When the pot lid is opened, the coolant in the clamping cavity flows back into the water storage component.

[0039] The aforementioned electric pressure cooker with a cooling function, after the high-pressure operation is completed, the high-pressure gas inside the pot enters the water storage container, pushes the piston, and causes the coolant inside the water storage container to enter the clamping cavity, cooling the lid. It uses the high-pressure steam after cooking in the electric pressure cooker as the power to pump the coolant, which is then delivered to the lid to achieve the required cooling effect, so that the lid can be opened quickly. It utilizes the high-pressure gas inside the pot, which is equivalent to releasing a portion for use in advance, and can also reduce the internal gas pressure, thus accelerating the opening of the lid.

[0040] Furthermore, when the lid is opened, the coolant in the clamping cavity flows back into the water storage container. The opening action allows the coolant to flow back and be recycled. This process is in line with actual usage and is easy to operate.

[0041] Furthermore, such as Figures 3 to 6 As shown, the top surface of the cover 230 is provided with a first settling groove 231, and a pad 232 is fixedly provided at the bottom of the first settling groove 231. The exhaust valve 250, exhaust pipe 260 and water pipe 270 are all provided on the pad 232. The air inlet ends of the exhaust valve 250 and exhaust pipe 260 extend to the bottom surface of the cover 230. A gasket 233 is fixedly provided at the edge of the first settling groove 231, and a sealing gasket 280 is provided above the gasket 233. A cover plate 290 is installed on top of the sealing gasket to form the clamping cavity 400. The side wall of the pad 232 corresponds to the water pipe. The bottom of 270 is provided with a return port 234, through which the water pipe 270 is connected to the clamping cavity 400; the cover plate is fixedly installed on the gasket and the gasket block by multiple bolts, which compresses the sealing gasket, thereby forming an effective sealing effect at the connection point and forming a clamping cavity with good airtightness; the modular assembly structure facilitates the processing and production of each structural component and makes it easy to disassemble and replace parts; it should be noted that the air inlet end of the exhaust valve and exhaust pipe are equipped with air caps for anti-clogging, which is a standard feature and will not be described in detail.

[0042] Furthermore, the water pipe is located at the end of the pad block away from the center of the lid, near the side of the lid's flipping and rotating fulcrum; the return port is located at the connection between the pad block and the gasket ring, passing through the opposite sides of the pad block and connecting to the bottom end of the water pipe; this structural design allows the return drainage part to be close to the bottom position after the lid is flipped open, which facilitates the smooth return of coolant and facilitates subsequent cooling.

[0043] Furthermore, the bottom surface of the cover plate 290 is fixedly provided with an inverted frustum-shaped protrusion 291, and the bottom surface of the protrusion 291 abuts against the bottom of the first recess 231; the top surface of the cover plate 290 is provided with a plurality of first grooves 292 corresponding to the protrusion, so that the protrusion 291 forms a thin-walled structure; this structural design can increase the contact area with the cover body through the protrusion, thereby facilitating the diffusion of heat, especially when the coolant enters the clamping cavity, increasing the contact area with the coolant and accelerating the cooling.

[0044] Furthermore, the top inner wall of the cover 230 is fixedly provided with multiple first lugs 235, which are used to install guide bolts 500; the bottom surface of the cover frame 210 is provided with a second recess 211, the shape of which is adapted to the shape of the cover 230; the top surface of the cover frame 210 is provided with a third recess 212, the bottom of which is provided with multiple first guide holes 213, which extend along the movement trajectory of the guide bolts, allowing the guide bolts to slide through the first guide holes and rotate the cover to be installed in the second recess; a post 236 is fixedly provided at the center of the cover 230, extending upwards and protruding from the top surface of the cover; the center of the third recess 212 is aligned with... A first circular hole 214 should be provided, the diameter of which is adapted to the diameter of the insert post 236. The insert post extends through the first circular hole to the third recess. The handle is installed on the insert post by the first bolt and is used to drive the cover to rotate. The cover frame, cover body and handle are assembled, which can facilitate the processing and production of each structural component and facilitate production assembly. The cover body is rotatably located at the second recess and is connected at its top by multiple guide bolts that are movably inserted through the first guide hole. This allows the cover body to be stably rotatably installed at the second recess and the force is transferred to the cover frame. The opening and closing can be adjusted by rotating the handle without the need for an additional locking structure.

[0045] Furthermore, the faceplate 220 is provided with a second circular hole 221; a limiting ring 215 is provided on the outer side of the first circular hole 214; the handle 240 includes a disc 241 and a grip bar 242, the diameter of the disc 241 is adapted to the inner diameter of the limiting ring 215; a first slot 243 is provided on the bottom surface of the disc 241, and a first locking block 237 is fixedly provided on the top of the insert 236; the first locking block 237 is engaged in the first slot 243 and fixed by a first bolt; a circular plate 244 is fixedly provided on the top surface of the disc 241, the diameter of the circular plate 244 is smaller than the diameter of the disc 241, and the diameter of the circular plate 244 is adapted to the diameter of the second circular hole 221. The cover is installed on the top of the third sink, allowing the disc to rotate and be clamped at the limiting ring. The handle is bolted to the top surface of the disc, located above the cover. This design makes the handle itself a separate structure, which is convenient for processing and assembly. In particular, the structure of the cover allows the handle to be positioned above the cover for easy gripping. The cover can limit the top of the disc, allowing it to rotate and be clamped at the limiting ring. Furthermore, an arc-shaped opening can be provided on the side wall of the limiting ring, and a pin can be installed on the side wall of the disc. The pin slides along the arc-shaped opening, which can further enhance the overall connection strength.

[0046] Furthermore, a pry plate for opening the exhaust valve is rotatably mounted on the pad, with the pressing end of the pry plate extending towards the insertion post; a fifth guide hole is provided on the disc, with a first support ring at the bottom end of the fifth guide hole, and a sixth guide hole is correspondingly provided on the handle, with a second support ring at the top end of the sixth guide hole; the device includes a pressing component and a spring, the pressing component including a pressing head, a pressing ring, and a pressing rod connected sequentially from top to bottom, the diameter of the pressing head being adapted to the inner diameter of the second support ring, and the diameter of the pressing ring being adapted to the inner diameters of the fifth and sixth guide holes. The diameter of the pressure rod is adapted to the inner diameter of the first support ring; the spring is sleeved on the outside of the pressure rod and clamped between the pressure ring and the first support ring, providing an upward pushing force for the pressing part, so that the pressure head protrudes from the top surface of the grip; the bottom end of the pressure rod protrudes from the bottom surface of the disc; the bottom of the third groove is provided with a seventh guide hole corresponding to the rotational movement trajectory of the pressure rod. When the handle is rotated, the bottom of the pressure rod slides along the seventh guide hole, maintaining the position of the pressing part corresponding to the end of the pry plate. By applying force to the pressing part, the exhaust valve can be manually opened.

[0047] The exhaust valve is equipped with a valve cap on top. The bottom of the third groove has an eighth guide hole corresponding to the rotational movement trajectory of the valve cap, and the valve cap slides along the eighth guide hole. A limiting frame is fixedly installed on the bottom surface of the cover. The inner wall shape of the limiting frame is adapted to the shape of the eighth guide hole, and the top of the valve cap extends into the limiting frame. An exhaust hole is provided on the top surface of the cover corresponding to the interior of the limiting frame. A rubber gasket is fixedly installed on the bottom surface of the limiting frame. After the panel cover is installed in place, the rubber gasket is squeezed to form a seal, which can reduce the gas entering the area between the third groove and the cover, thus protecting the electrical components in this area.

[0048] Furthermore, the top of the exhaust pipe extends upwards, passing through the second guide hole and into the third recess, the second guide hole extending along the rotational movement trajectory of the exhaust pipe; the top of the outlet pipe of the first solenoid valve extends upwards, passing through the third guide hole and into the third recess, the third guide hole extending along the rotational movement trajectory of the outlet pipe of the first solenoid valve; as... Figure 7 As shown, the third settling groove 212 has a fourth settling groove 216 on both sides near the rotating end of the lid; the bottom of the wall surface of the lid frame 210 near the rotating end of the lid has a second groove 217; the fourth settling groove 216 and the second groove 217 are connected by a third round hole 218; as shown Figure 8 As shown, the wall surface of the pot body 100 near the rotating end of the lid is provided with a third groove 110, the top of the third groove is open, and second lugs 120 are fixed on both sides of the top of the third groove 110; the second lugs 120 are provided with a first threaded hole 121, the diameter of the first threaded hole is larger than the diameter of the third circular hole; as shown Figure 2 As shown, a hollow bolt 600 is installed at the first threaded hole 121. The part of the hollow bolt that inserts into the third circular hole is the smooth outer wall of the rod, allowing the pot lid to rotate and be installed on the pot body. The water storage component 310 is installed at the third groove 110. The gas supply hose 320 and the water supply hose 330 are respectively movably inserted through the hollow bolts 600 on both sides and the fourth recess 216, leaving sufficient length to accommodate the rotation of the lid. This structural design provides space for the gas supply hose and the water supply hose to pass through, which can meet the required gas and water supply effects, and also prevent the pot lid from being flipped up or the lid body from rotating, so that there will be no interference between the movement of the components.

[0049] Furthermore, one side wall of the third groove is provided with a first through hole that communicates with the interior of the outer shell of the pot. A control panel is installed on the cover. The wiring of the first solenoid valve and the control panel is also passed through hollow bolts and then through the first through hole into the interior of the outer shell to make electrical connections with other electrical components. This is a relatively conventional wiring and connection method, which will not be described in detail.

[0050] Furthermore, such as Figures 9 to 12As shown, the water storage component 310 includes a box 311 with an open bottom and a sealing cap 312 that is fitted onto the bottom of the box 311; the box body adapter is fitted into the third groove and fixedly installed by bolts; a partition 313 is fixedly provided inside the box 311, dividing the interior of the box 311 into a water storage chamber 314 and an air passage 315, the bottom end of the water storage chamber is connected to the bottom end of the air passage, and a piston 340 is located inside the water storage chamber 314; an air nozzle 316 is connected to the top of the air passage 315, and the end of the air supply hose 320 is connected to the air nozzle 316; a bottle is connected to the top of the water storage component 310. The bottle mouth 317 is covered with a bottle cap 350. The top of the bottle cap 350 is connected to a pipe head 351, which is connected to the end of the water supply hose 330. The above structural design makes the entire water supply mechanism an assembled structure, which facilitates the processing and production of each structural component, as well as production assembly and disassembly and replacement. The bottle cap is a union or plug-in joint structure, which can be adjusted to fit the bottle mouth to achieve quick connection and facilitate the replacement of coolant inside the box. It will not cause twisting or bending of the water supply hose and maintains a smooth passage.

[0051] Furthermore, the bottom side wall of the air passage 315 is provided with an external exhaust hole 318, and a second solenoid valve 360 ​​is installed at the external exhaust hole 318, such as... Figure 2 As shown, the output end of the second solenoid valve extends through the bottom outer wall of the pot body; since high-pressure steam is used, some water droplets will condense. The design of the second solenoid valve can be used to discharge liquid inside the gas passage; it can also be used as an exhaust point to facilitate the rapid reduction of gas pressure inside the gas passage, causing the piston block to descend, which naturally facilitates subsequent backflow.

[0052] Furthermore, a guide post 319 is fixedly provided on the top surface of the cover 312, with the center of the guide post corresponding to the center of the water storage chamber; a fourth guide hole is provided at the center of the piston, and a first sealing slip ring is provided on the inner wall of the fourth guide hole; the piston is slidably sleeved on the guide post, and a sealed sliding fit is formed through the first sealing slip ring; a second sealing slip ring is provided on the outer wall of the piston, and the outer wall of the piston is sealed and slidably fitted with the inner wall of the water storage chamber through the second sealing slip ring; this can effectively limit the movement of the piston block, reduce the influence of lateral forces, and make the piston block move smoothly up and down, effectively pushing the coolant above, and also preventing leakage and water seepage problems. Furthermore, a support ring is fixedly provided on the bottom side wall of the guide post, with the top surface of the support ring not lower than the bottom surface of the partition plate, for supporting the piston, so that the bottom end of the air passage is connected to the bottom of the water storage chamber, ensuring that gas can enter the water storage chamber and push the piston;

[0053] Furthermore, the top surface of the guide column is provided with a locking hole, and the top inner wall of the water storage chamber is provided with a corresponding locking post. When the cover is installed in place, the end of the guide column abuts against the top inner wall of the water storage chamber, and the locking post extends into the locking hole to provide limited support for the guide column, so that it maintains an upright position, so that the piston can move up and down smoothly.

[0054] Furthermore, the bottom surface of the cover is provided with a second locking block, and the bottom end of the third groove is provided with a second locking groove, with the second locking block locking into the second locking groove; the top surface of the box is fixedly provided with a vertical plate, which abuts against the bottom of the third groove and is fixedly connected by bolts; thus, the water storage component is stably installed in the third groove.

[0055] Furthermore, the water storage chamber 314 has an open opening at the top of the wall near the pot body, and a heat exchange hood 370 is sealed and installed at the open opening, which is in contact with the coolant in the water storage chamber. A semiconductor cooling chip 380 is installed inside the heat exchange hood 370, with the cooling surface of the semiconductor cooling chip in close contact with the heat exchange hood and the heating surface of the semiconductor cooling chip extending outward from the outside of the heat exchange hood. The heat exchange hood is a copper structure with good thermal conductivity. Heat-conducting plates can also be installed on the inner wall of the heat exchange hood in the water storage chamber to increase the contact area with the coolant, thereby improving the heat exchange efficiency and allowing the coolant to cool down to the required temperature more quickly. Since the amount of coolant does not change much, the approximate water temperature can be determined by controlling the working time of the semiconductor cooling chip. Of course, a temperature sensor can also be installed in the water storage chamber to detect the water temperature and achieve more accurate control. Temperature sensors are common electrical components, and their installation and use are relatively conventional, so details will not be elaborated.
