Description

Technical Field

[0001] This invention relates to the field of cooking appliances, and more specifically, to a stew pot with a water replenishment function. Background Technology

[0002] Slow cookers are a common household cooking appliance. During operation, the water in the inner pot is converted into boiling steam, which is released through the vent on the lid. Steaming and stewing generally require a long time, especially slow cooking, which can last for more than ten hours. Current slow cookers, to prevent the water from boiling dry and to allow for adding water midway, have a relatively large inner pot, leaving a wide gap between the inner wall and the inner pot to allow for adding more water at once. However, this increases the surface area for water evaporation, accelerating water loss and causing the water level to drop. This reduces the area of ​​the inner pot covered by hot water, resulting in uneven heating and affecting the cooking of the food inside. Furthermore, current slow cookers do not have an automatic water replenishment function, requiring manual addition of water midway, which is cumbersome and needs improvement. Summary of the Invention

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 5 As shown, a specific embodiment of the present invention discloses a stew pot with a water replenishment function, including a pot body 300 and a pot lid 100; the inner liner 310 of the pot body 300 has multiple through holes on its side wall, and a soft rubber membrane 311 is provided at the through holes; the pot body 300 has a push mechanism 400 inside, which includes multiple push members 510, which are arranged corresponding to the soft rubber membrane 311. The push members are adjusted to push the soft rubber membrane inward, reducing the internal water storage space; the pot lid 100 has a water storage cavity 140 inside, and the bottom of the water storage cavity 140 has a drain hole 116 for draining water into the inner liner. A sealing component 200 is provided above the drain hole 116. The sealing component is used to seal the drain hole and maintain a normally blocked state; the sealing component is adjusted to release the blockage of the drain hole and replenish water to the pot body.

[0038] The aforementioned stew pot with water replenishment function can initially inject a large amount of water into the inner pot. During the later cooking and evaporation process, the push mechanism squeezes the soft rubber film to reduce the internal space of the inner pot, thereby maintaining the internal water level at the required height. This ensures that the hot water maintains sufficient coverage of the heating surface on the outside of the stew pot, improving stewing efficiency and quality, and increasing heat utilization.

[0039] Furthermore, the clever use of the lid as a water storage area does not occupy external space, making the overall structure more compact; it also gives the lid a certain weight, preventing it from being easily lifted by steam and accelerating heat loss; after the pushing mechanism is activated, the inner pot maintains the space after the pushing, and water is added appropriately when replenishing it, reducing the energy consumption of secondary heating, reducing power consumption and waste.

[0040] Furthermore, such as Figure 4 , Figure 5As shown, the pot lid 100 includes a lid body 110, a conical cover 120, and a sealing assembly 200. The lid body 110 has an internal cavity 111, with an opening 112 at the bottom. A protruding ring 113 is fixedly attached to the outer side of the bottom end of the opening 112, the outer diameter of which matches the inner diameter of the top of the inner liner 310. A first tube 114 is fixedly attached to the center of the top surface of the cavity 111, and its inner wall is threaded. The bottom diameter of the conical cover 120 matches the inner diameter of the protruding ring 113, and a second tube 121 is fixedly attached to the top of the conical cover 120. The outer diameter of the second tube matches the inner diameter of the first tube, and its outer wall is threaded. The second tube 121 and the first tube 114 are threadedly connected. The open opening 112 is sealed, forming the water storage chamber 140 inside the lid; the top of the lid is provided with a water inlet, and a cap is installed on the outside of the water inlet; the top surface of the lid is provided with an exhaust hole communicating with the inside of the first tube; the second tube communicates with the inside of the cone shroud; the drain hole 116 is provided corresponding to the convex ring 113 and penetrates the bottom surface of the convex ring; the sealing component is installed inside the clamping cavity and is provided corresponding to the drain hole; the whole is an assembled structure, which facilitates the processing and production of each structural component and is also convenient for production assembly, forming a water storage chamber with a large space, which can store more water to prepare for later water replenishment; in addition, the bottom of the cone shroud is a concave part with a certain vertical space height, which is convenient for matching and using taller stewing pots;

[0041] Furthermore, a boss is fixedly provided at the center of the top surface of the lid, and a pull head for gripping and lifting is fixedly provided at the center of the top surface of the boss, making it convenient to put on and take off the lid; the inside of the boss is provided with a groove that communicates with the first tube, and the side wall of the boss is provided with multiple vent holes to form a channel for external ventilation.

[0042] Furthermore, a first sealing ring is fitted around the bottom edge of the cone cover to enhance the sealing performance of the connection with the convex ring; and a pressure ring is fixedly provided on the bottom edge of the cone cover. When the cone cover is installed in place, the pressure ring presses against the bottom surface of the convex ring to further enhance the connection strength and sealing performance, effectively preventing water seepage and leakage problems.

[0043] Furthermore, such as Figure 5 , Figure 6As shown, the sealing assembly 200 includes a plug 210, a first spring 220, a rocker 230, and a support frame 240 with an open bottom. The plug 210 includes a plug head 211, with a first guide rod 212 fixedly mounted on the top of the plug head 211, and a support ring 213 fixedly mounted on the bottom side wall of the first guide rod 212. A first guide hole 241 is provided at the top of one end of the support frame 240, and the first guide rod 212 is movably inserted through the first guide hole 241, with a retaining spring at its top to prevent dislodgement. The first spring 220 is sleeved on the first guide rod 212 and clamped between the support ring 213 and the top of the support frame 240, serving as the plug... The component provides a downward pushing force; the rocker arm 230 is rotatably mounted on the support frame 240 via a pin 250, and one end of the rocker arm has a latch that engages between the support ring and the plug; a magnet 260 is fixedly mounted on the bottom surface of the end of the rocker arm 230 away from the latch; a clamping frame 115 is fixedly mounted inside the clamping cavity 111 corresponding to the drainage hole, the support frame 240 is engaged with the clamping frame 115 and fixed by bolts, the plug is inserted into the drainage hole, and the other end of the rocker arm tilts upward; the sealing assembly is an assembled structure, which facilitates the processing and production of each structural component and makes it easy to assemble, making it a modular structure that is easy to assemble with the clamping frame inside the clamping cavity; such as Figure 2 , Figure 7 As shown, an electromagnet 360 is fixedly embedded on the top of the pot body 300 corresponding to the magnet block 260. When the electromagnet is energized, it can drive the magnet block to move down, pry up the plug, and release the blockage of the drain hole. The magnetic attraction is used as the power to release the blockage component. On the one hand, it can realize the drainage as needed, and on the other hand, it can maintain the sealing of the water storage chamber to prevent the internal liquid from flowing out easily.

[0044] Furthermore, the number of drain holes is preferably four, and they are respectively set at the four corners. The number of clamping frames set is four, which are set at the drain holes and are close to the open part, so as to facilitate the disassembly and assembly of the sealing components. Four electromagnets are fixedly embedded at the four corners of the top surface of the pot body, which is convenient for matching and use, and does not require deliberate alignment and sealing.

[0045] Furthermore, such as Figure 3 , Figure 7 , Figure 8As shown, the pot body 300 includes an inner liner 310, a shell 320, a bottom cover 330, a heating plate 340, a pushing mechanism 400, a level gauge 350, and an electromagnet 360. The shell 320 has recessed grooves at its four top corners for mounting the electromagnet 360. The inner liner 310 is fixedly mounted on the top of the shell 320 and extends towards the bottom of the shell. The heating plate 340 is installed at the bottom of the inner liner 310, with the heating area located inside the inner liner. The level gauge 350 is installed at the bottom of the inner liner 310, with its probe extending into the interior of the inner liner. It is an assembled structure, facilitating the processing and production of various structural components and simplifying assembly. Four perforations are distributed at the four corners of the shell and extend laterally along the curved surface, providing a large deformable space. The pushing mechanism includes four pushing components, each corresponding to one of the four perforations, ensuring a more balanced force on the inner liner and effectively pushing the soft membrane, thereby changing the internal dimensions of the inner liner.

[0046] Furthermore, the vertical opening length of the perforation is between 1 / 2 and 3 / 4 of the inner liner depth, and the angle between the two ends of the perforation and the center of the inner liner is between 70° and 80°. This can maintain the structural strength required for the inner liner, prevent easy deformation and damage, and also provide a large enough deformation space to facilitate the pusher to move inward a sufficient distance, making the internal space of the inner liner change more obvious.

[0047] The bottom of the settling tank is provided with a wire hole that communicates with the inside of the housing for wiring the electromagnet; and the connection between the electromagnet and the settling tank is filled with sealant to prevent water seepage and leakage.

[0048] It should be noted that the soft film is a closed-loop silicone film structure, and the inner liner is made of one of the following plastics, including but not limited to PEEK, PESU, and PPS. The soft film and the inner liner are integrally molded and can be placed in the molding mold before the inner liner is produced and processed, so that the inner liner wraps and connects the soft film, ensuring the connection strength and stability of the overall structure and preventing the soft film from falling off or being damaged.

[0049] Furthermore, the bottom inner wall of the inner pot is fixedly provided with a first protrusion or a first groove, and the bottom of the matching stew pot is correspondingly provided with a second groove or a second protrusion, which limits the placement position of the stew pot so that it is placed in the center, and the side wall is left with space to push the soft rubber film, which facilitates actual operation.

[0050] Furthermore, such as Figure 3 , Figures 7 to 11As shown, the pushing mechanism 400 includes a motor 410, a transmission component 420, and four pushing structures 500. Each pushing structure 500 includes a pushing member 510, a support base 520, guide bolts 530, a second spring 540, and a limiting assembly 550. The support base 520 is installed at the inner corner of the housing 320. The pushing member 510 is movably mounted on the support base 520 via multiple guide bolts 530. The guide bolts are parallel to the line connecting the corner of the housing and the center of the housing, and the pushing member moves along the guide bolts. The second spring 540 is sleeved on the guide bolts 530 and clamped between the pushing member 510 and the support base 520, providing the pushing member 510 with a pushing force towards the inner liner. The limiting assembly 550 is used for... The pusher 510 moves outward; the motor 410 is connected to four limiting components 550 via the transmission component 420, synchronously driving the multiple limiting components to change the degree of blocking and pressing on the pusher, thereby changing the pushing depth of the pusher on the soft film; the second spring is used as the elastic force for the pusher to move outward, which can provide continuous force; and the adjustment by changing the degree of blocking and pressing of the limiting components can better adapt to the small space inside the housing, facilitate the layout of the overall structure, and meet the required adjustment of the pusher effect; in addition, multiple pusher structures are driven by the same motor, which can further reduce the space occupation, facilitate the layout of other structures, and reduce power consumption and cost.

[0051] Furthermore, such as Figures 10 to 12As shown, the pusher 510 includes a push plate 511, and two opposing support blocks 512 are fixedly mounted on the wall of the push plate 511 near the support base. The support blocks 512 have a first countersunk hole 513 on their wall near the support base, and a corresponding second countersunk hole is provided on the wall of the push plate. The first and second countersunk holes are connected by a second guide hole. The support base 520 has a third countersunk hole 521 corresponding to the first countersunk hole, and a first threaded hole is provided at the center of the third countersunk hole. A guide bolt movably passes through the second guide hole, and its end is threadedly connected to the first threaded hole. A second spring 540 is sleeved on the second guide bolt 530, with both ends extending into the first countersunk hole 513 and the third countersunk hole 521, respectively. A limiting block 514 is fixedly mounted on one side of the inner wall of the support block 512, and the bottom of the limiting block 514 has a first inclined surface 5. 15. The first inclined surface is inclined downwards towards the side away from the push plate; the limiting assembly 550 includes a lead screw 551, a sliding sleeve 552 is sleeved on the lead screw 551, a stop block 553 is fixed on the sliding sleeve 552, and a second inclined surface 554 is provided on both sides of the stop block 553; the lead screw 551 passes between the two limiting blocks 514, and the second inclined surface 554 slides with the first inclined surface 515. The degree of blocking and pressing on the push member is changed by adjusting the position of the sliding sleeve; the cooperation between the lead screw and the sliding sleeve serves as a structure to block the movement of the push member. On the one hand, the rotational motion can be converted into linear motion so that the first inclined surface and the second inclined surface can cooperate, thereby allowing the push member to move smoothly; on the other hand, the tighter cooperation between the lead screw and the sliding sleeve allows for more accurate adjustment, thereby achieving more precise control.

[0052] Furthermore, the top inner wall of the housing is provided with multiple first grooves corresponding to multiple lead screws, and a first bearing is engaged at the first groove;

[0053] The bottom of the inner liner is equipped with outwardly extending brackets corresponding to multiple lead screws. The brackets are provided with second recesses, and second bearings are engaged in the second recesses. The lead screws are rotatably mounted between the first bearing and the second bearing. The transmission component 420 includes a ring plate 421. A toothed ring 422 is fixedly provided on the bottom surface of the ring plate 421. The toothed ring 422 has the same inner diameter as the ring plate 421 and is adapted to the outer wall diameter of the inner liner 310. The transmission component 420 is rotatably sleeved on the inner liner 310. The ring plate 421 slides against the top inner wall of the shell 320 and is supported by multiple blocks 370 installed on the top inner wall of the shell. The outer wall of the inner liner is used as a rotation limiting component, and the blocks provide sliding support, thereby allowing the toothed ring to rotate at the set position.

[0054] The top of the lead screw 551 is fixedly equipped with a first gear 555, and the output shaft of the motor 410 is fixedly equipped with a second gear 411. The second gear 411 and multiple first gears 555 mesh with the gear ring 422 to achieve one motor driving multiple pushing structures to move. The top of the opposite side walls of the outer shell is equipped with a handle. The handle has a cavity inside, one of which has a through-hole to the outside. A plug is inserted at the mounting hole and fixed with bolts. The motor is mounted on the plug with bolts. Using the handle as its mounting point can better adapt to the gear ring for transmission and facilitate the layout of other structures, thereby improving space utilization.

[0055] Furthermore, such as Figure 13 As shown, clamping grooves 321 are fixedly provided on both sides of the corner of the housing 320; as Figure 10 , Figure 11 As shown, the wall surface of the support base 520 away from the pusher is adapted to the shape of the inner wall at the corner of the housing, and the support base is set tightly against the inner wall at the corner of the housing; the two sides of the support base 520 are provided with corresponding clamping plates 522, the clamping plates 522 are adapted to the shape of the clamping groove 321, and the clamping plates are clamped in the clamping groove; the support base is clamped by the bottom cover that is closed on the bottom of the housing, so that the support base is in the required height position; this structural design can facilitate the installation of the support base, which means that it can facilitate the installation of the entire pusher structure, and can make the pusher and the soft rubber membrane accurately aligned; of course, holes can also be opened in the clamping groove and clamping plate for reinforcement connection by bolts, and the above-mentioned clamping fit is not the only assembly method;

[0056] Furthermore, the top inner wall of the housing is provided with multiple pads, each with a second threaded hole. The support block has a round hole in the middle and is fixed to the pads with bolts. The top surface of the support block slides against the bottom surface of the ring plate to provide sliding support for the transmission component. In addition, the side of the support block near the clamping groove has a cutting surface that abuts against the outer wall of the clamping groove, preventing the support block from rotating and effectively preventing it from rotating and loosening during later use. It should be noted that the transmission connection parts and sliding contact parts inside the housing are coated with lubricating oil to maintain the coordinated operation and movement of the various structural components.

[0057] Furthermore, the wall surface of the pusher plate away from the support block has an outwardly convex arc structure, with the arc diameter matching the diameter of the soft rubber film, and the arc length of the pusher plate being less than the arc length of the soft rubber film. The overall size of the pusher plate is smaller than the size of the soft rubber film, which facilitates better inward pushing of the pusher plate. Moreover, during the inward pushing process, the contact surface gradually increases, which better adapts to the law of water evaporation and gradual decrease in water level, and better maintains the water level height. Furthermore, the edges of the pusher plate are rounded to prevent scratches or tears to the soft rubber film, extending its service life.

[0058] This invention has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. This invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims are also within the protection scope of this invention.
