Description

Technical Field

[0001] This invention relates to the field of pressure cooker technology, and specifically to a pressure cooker with a pressure display and warning function. Background Technology

[0002] A pressure cooker is a kitchen appliance that utilizes the physical phenomenon that the boiling point of a liquid increases under higher pressure, allowing water to reach a higher temperature without boiling, thus speeding up the cooking process. It can heat food to over 100°C. In high-altitude areas, pressure cookers can avoid the problem of water boiling point dropping and food not cooking properly.

[0003] Currently, there are various types of household pressure cookers, including those with timers and those that display the timer. However, there are no pressure cookers that can measure and display the internal pressure to warn the operator. During the use of a pressure cooker, improper operation, such as rice grains when cooking porridge or Chinese medicinal herbs like goji berries when making soup, can clog the pressure cooker's exhaust valve, causing the internal pressure to rise and potentially leading to an explosion. This results in low safety. Additionally, after the pressure cooker is opened, the exhaust valve produces a large amount of steam, which is currently released directly into the atmosphere, resulting in heat loss and waste. There are also issues with pressure cookers not being able to measure and display the internal pressure and not being able to reuse the released steam. Summary of the Invention

[0004] To address the shortcomings of existing pressure cookers, such as their inability to measure and display internal pressure and their inability to reuse the released steam, this invention designs a pressure cooker with a pressure display and warning function.

[0011] Preferably, a pressing groove is provided on the outer side of the pot body at the position corresponding to the pressing block, and both ends of the first moving block are slidably connected to the fixed box through a sliding rod, and both ends of the transmission rod are rotatably connected to the first moving block and the second moving block respectively.

[0012] Preferably, the pot lid has an internal venting groove, and an venting valve is fixedly connected to the top of the pot lid and outside the venting groove. A lever is fixedly connected to the bottom of the venting valve. A pot handle is fixedly connected to the front end of the pot lid. A fulcrum groove adapted to the lever is provided at the top of the pot handle. A buckle is rotatably connected to the front end of the lever, and a locking groove adapted to the buckle is provided at the front end of the pot handle.

[0013] Preferably, the top of the outer side of the inner pot is symmetrically connected with a handle, and the outer side of the pot body is provided with a positioning groove that is adapted to the handle.

[0016] The beneficial effects of this invention are:

[0017] 1. Through the design of the pot body and pressure sensing mechanism, if the pressure cooker is operated improperly and the exhaust valve becomes blocked, the air pressure inside the pot body will continue to increase. The pressure will act on the inside of the pressure channel, pushing the top ball down and causing the first spring to start compressing. The moving column will slide down in the pressure channel until it touches the pressure sensor. The pressure sensor is electrically connected to the operation panel through a wire, so that the pressure value of the pressure sensor is displayed on the screen. As the pressure gradually increases until the pressure sensor reaches the warning value, an alarm will be displayed on the screen, so that the user can know that there is a problem with the pressure cooker, thereby improving the safety of using the pressure cooker.

[0018] 2. Through the design of the lid and steamer, during the use of the pressure cooker, as the internal pressure increases, excess gas is continuously released through the exhaust valve, ensuring the stability of the internal pressure. The gas is released through the exhaust channel and then steadily discharged through the exhaust valve. To avoid wasting hot steam, the steamer is placed on the lid to fully utilize the hot steam released from the pot to heat the food. When it is necessary to open the lid to release pressure, press the front end of the lever to put the buckle on the front end of the handle, so that the buckle is locked in the slot. At this time, the rear end of the lever will lift the exhaust valve to improve the exhaust efficiency, so that the internal pressure of the pot will drop as quickly as possible, making it easy to open and pour out the steamed food. At the same time, the released hot steam can also quickly enter the steamer to heat the food, thus making full use of the heat of the steam and improving the practicality and applicability of the pressure cooker.

[0027] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example

[0029] like Figures 1 to 7 As shown, a pressure cooker with pressure display and warning function includes: a pot body 1 and a pot lid 2. The pot lid 2 is rotatably connected to the top of the pot body 1. An inner pot 3 is installed inside the pot body 1. A pressure sensing mechanism 4 is fixedly installed at the front end inside the pot body 1. An operation panel 5 is fixedly installed on the front of the pot body 1. A display screen 6 is fixedly connected to the top of the operation panel 5. A steamer 7 is mounted on the top of the pot lid 2.

[0030] The pressure sensing mechanism 4 includes a water guide box 401 fixedly installed inside the front end of the pot body 1. A pressure channel 402 is provided inside the water guide box 401. A moving column 403 is slidably connected to the inner side of the pressure channel 402. A first spring 404 is fixedly connected inside the pressure channel 402 and outside the moving column 403. A top ball 405 is fixedly connected to the top of the first spring 404, and the top of the moving column 403 is fixedly connected to the top ball 405. A pressure sensor 406 is fixedly connected to the bottom end of the water guide box 401 and below the moving column 403. The bottom end of the pressure sensor 406 is electrically connected to the operation panel 5 via a wire 407. In case of improper operation of the pressure cooker causing a continuous increase in pressure inside the pot body 1... After the pressure increases, the pressure acts on the inside of the pressure channel 402, pushing the top ball 405 down, causing the first spring 404 to begin to compress. The moving column 403 slides downward in the pressure channel 402 until it touches the pressure sensor 406. The pressure sensor 406 is electrically connected to the operation panel 5 through the wire 407, so that the pressure value of the pressure sensor 406 is displayed on the display screen 6. As the pressure gradually increases until the pressure sensor 406 reaches the warning value, the display screen 6 will display an alarm, so that the user can know that there is a problem with the pressure cooker. At this time, the power should be turned off first, and the lid 2 should be opened to release the pressure. Then the first spring 404 will reset and push the top ball 405 up, causing the moving column 403 to move upward and the pressure value to return to zero.

[0031] Multiple sets of rubber anti-slip pads 101 are fixedly connected to the inner side of the bottom of the pot body 1. A power plug 102 is fixedly connected to the bottom of the front of the pot body 1. An electromagnetic heating plate 103 is fixedly connected to the bottom of the inner pot 3 inside the pot body 1. When the pot body 1 is used flat, the friction of the bottom of the pot body 1 is increased by the multiple sets of rubber anti-slip pads 101, thereby preventing the pot body 1 from tipping over when it is hit. The pot body 1 is connected to electricity through the power plug 102 at the bottom. The pressure cooker in this solution is an electric pressure cooker. After being connected to electricity, the inner pot 3 is electromagnetically heated by the electromagnetic heating plate 103.

[0032] A water collection groove 104 is provided at the top of the inner pot body 1 and on the outside of the inner liner 3. A water guide box 401 is provided at the top and at the bottom of the water collection groove 104. A first water collection box 106 is snapped onto the front of the pot body 1. A drainage channel 107 is provided inside the pot body 1 and on the inside of the first water collection box 106. A drainage groove 108 is provided on the side of the water guide box 401 near the drainage channel 107. When the pot body 1 is in use, the food inside the inner liner 3 begins to heat up. The water vapor condenses into water and flows into the inside of the water collection groove 104. The water collection groove 104 can improve the temperature of the pot body. The sealing between the pot body 1 and the lid 2 is maintained. As the pressure inside the pot body 1 increases, the pressure acts on the inside of the pressure channel 402, causing the top ball 405 to push down, so that water is discharged into the water guide box 401 through the water guide port 105, and then enters the first water collection box 106 through the drain groove 108 and the drain channel 107, thereby draining excess water. When the pressure value is normal, the top ball 405 pushes up to close the water guide port 105, thereby ensuring the pressure inside the pot body 1. The first water collection box 106 can be removed from the inside of the pot body 1 after the pot body 1 is used, and the water accumulated inside the first water collection box 106 can be poured out.

[0033] The front end of the lid 2 is rotatably connected to the pot body 1 via a pivot 201. A latching groove 202 is provided at the front end of the top of the lid 2. A fixing box 203 is fixedly connected to the rear end of the lid 2. The front end of the lid 2 is rotatably connected to the pot body 1 via a pivot 201. After the food is steamed or cooked, the lid 2 can be opened by first releasing the fixing of the lid 2 and then using the latching groove 202.

[0034] A pressing block 204 is slidably connected to the top of the fixing box 203. A first moving block 205 is fixedly connected to one end of the pressing block 204 inside the fixing box 203. A second spring 206 is fixedly connected to the bottom of the first moving block 205 inside the fixing box 203. A second moving block 207 is slidably connected to the front end inside the fixing box 203. A plug 208 is fixedly connected to the front of the second moving block 207. A socket 209 is provided on the top of the pot body 1 to fit the plug 208. The second moving block 207 and the first... A transmission rod 210 is rotatably connected between the movable blocks 205. When the pot lid 2 is closed, the insert pin 208 is inserted into the socket 209 to fix the pot lid 2 and the pot body 1. After the food inside the pot body 1 is cooked, simply press down on the pressing block 204 to move the first movable block 205 down. Then, under the transmission of the transmission rod 210, the second movable block 207 is pulled backward, thereby moving the insert pin 208 backward and moving it out from the inside of the socket 209, thus releasing the fixation of the pot lid 2. At this time, the pot lid 2 can be opened by flipping it upward.

[0035] A pressing groove is provided on the outer side of the pot body 1 at the position corresponding to the pressing block 204. The front and rear ends of the first moving block 205 are slidably connected to the fixed box 203 through the slide rod 211. The front and rear ends of the transmission rod 210 are rotatably connected to the first moving block 205 and the second moving block 207 respectively. Pressing down on the pressing block 204 causes it to move downward in the pressing groove, while the first moving block 205 moves downward stably under the connection of the slide rod 211. Then, under the connection of the transmission rod 210, the second moving block 207 is pulled to move.

[0036] The pot lid 2 has an internal venting groove 212. A venting valve 213 is fixedly connected to the top of the pot lid 2, outside the venting groove 212. A lever 214 is fixedly connected to the bottom of the venting valve 213. A pot handle 215 is fixedly connected to the front end of the pot lid 2. The top of the pot handle 215 has a fulcrum groove 216 adapted to the lever 214. A retaining ring 217 is rotatably connected to the front end of the lever 214. A locking groove 218 adapted to the retaining ring 217 is located at the front end of the pot handle 215. During normal use of the pot body 1, the retaining ring 217 is first rotated out from the inside of the locking groove 218, causing the front end of the lever 214 to tilt upwards under the action of the fulcrum groove 216. As the internal pressure of the pot body 1 begins to rise, gas is discharged through the venting groove 212. The steam is then steadily released through the exhaust valve 213. To avoid wasting hot steam, the steamer 7 is placed on the lid 2, and the hot steam is used to heat the food inside the steamer 7, such as frozen buns or steamed bread. When it is necessary to open the lid 2 to release pressure, the front end of the lever 214 is pressed down to put the buckle 217 on the front end of the handle 215, so that the buckle 217 is locked into the slot 218 for fixation. At this time, the rear end of the lever 214 will lift the exhaust valve 213 to improve the exhaust efficiency, so that the pressure inside the pot 1 is reduced as quickly as possible, making it easy to open and pour out the steamed food. At the same time, the released hot steam can also quickly enter the interior of the steamer 7 to heat the food, thereby making full use of the heat of the steam and improving the practicality of the pressure cooker.

[0037] The top of the outer side of the inner pot 3 is symmetrically connected with a handle 301. The outer side of the pot body 1 is provided with a positioning groove 302 that is adapted to the handle 301. After the food in the pot body 1 is cooked, the pressure inside the pot body 1 is released. After the pressure is released, the inner pot 3 is taken out from the inside of the pot body 1 through the handle 301. When the inner pot 3 containing food is put into the inside of the pot body 1, it can be quickly installed and positioned through the positioning groove 302.

[0038] The bottom of the steamer 7 has a rack groove 701 that is compatible with the lid 2. The bottom of the steamer 7 is fixedly connected to a steam inlet 702. The top of the steamer 7 is equipped with a food container 703. The bottom of the food container 703 has multiple vent holes. The top of the food container 703 is covered with a sealing lid 704. After the pressure inside the pot 1 increases, excess gas will be continuously discharged through the exhaust valve 213, thereby ensuring the stability of the internal pressure of the pot 1. At this time, the steamer 7 is placed on top of the lid 2 through the recessed rack groove 701 at the bottom of the steamer 7, ensuring the stability of the steamer 7 during use. At the same time, the steam inlet 702 is connected to the exhaust valve 213. Food that needs to be heated is placed in the food container 703. The hot steam discharged from the pot 1 enters the interior of the steamer 7. Then the hot steam heats the food through the vent holes at the bottom of the food container 703. The hot steam discharged from the pot 1 is fully utilized to heat the food, which improves the applicability of the pressure cooker.

[0039] A cover handle 705 is symmetrically connected to the outer side of the sealing cover 704, and a water collection cover 706 is fixedly connected to the inner side of the sealing cover 704. Multiple sets of vent holes 707 are opened on the outer side of the water collection cover 706. A second water collection box 708 is threadedly connected to the bottom end of the water collection cover 706. The sealing cover 704 is opened by the cover handle 705, and the food to be heated is placed in the cooking pot 703. As the water vapor in the steamer 7 increases, the condensed water droplets will drip onto the food, causing the food to become more moist and affecting the taste. At this time, the hot steam enters the interior of the water collection cover 706 through the vent holes 707 on the outer side of the water collection cover 706. Then the hot steam condenses into water in the water collection cover 706 and is collected through the second water collection box 708 at the bottom end of the water collection cover 706. After opening the sealing cover 704, the second water collection box 708 can be unscrewed from the bottom end of the water collection cover 706 to pour out the water.

[0040] Implementation Plan: First, insert the inner pot 3 containing food into the pot body 1, then cover it with the lid 2. With the lid 2 closed, the insert pin 208 is inserted into the socket 209 to secure the lid 2 to the pot body 1. After the food inside the pot body 1 is cooked, simply press down on the pressing block 204 to move the first moving block 205 downwards. Then, driven by the transmission rod 210, the second moving block 207 is pulled backwards, causing the insert pin 208 to move backwards and out of the socket 209, thus releasing the lid 2. The lid 2 can then be opened by flipping it upwards. During pressure cooker use, as the pressure inside the pot body 1 increases, excess gas is continuously released through the exhaust valve 213, ensuring the stability of the pressure inside the pot body 1. The gas is discharged through the exhaust groove 212 and then through the exhaust valve. 213 is stably discharged. To avoid wasting hot steam, the steamer 7 is placed on the lid 2 to fully utilize the hot steam discharged from the pot 1 to heat the food. This fully utilizes the heat of the steam and improves the practicality of the pressure cooker. When the exhaust valve 213 is blocked, the pressure inside the pot 1 will continue to rise. The pressure acts on the inside of the pressure channel 402, pushing the top ball 405 down, causing the first spring 404 to start compressing. The moving column 403 slides down in the pressure channel 402 until it touches the pressure sensor 406. The pressure sensor 406 is electrically connected to the operation panel 5 through the wire 407, so that the pressure value of the pressure sensor 406 is displayed on the display screen 6. As the pressure gradually increases until the pressure sensor 406 reaches the warning value, an alarm is displayed on the display screen 6.

[0041] This invention improves the safety of pressure cookers by displaying and alarming the pressure after improper operation that causes the internal pressure to rise continuously. At the same time, it can make full use of the heat from the steam released from the pressure cooker to heat other foods, further enhancing the applicability of the pressure cooker.

[0042] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.

[0043] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
