Description

Technical Field

[0001] This invention relates to the field of rice cookers, and more specifically, to a support mechanism and a rice cooker. Background Technology

[0002] Many rice cookers currently use a heating plate as the heating element, which is in direct contact with the inner pot.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 4 As shown, a specific embodiment of the present invention discloses a support mechanism, including a support structure 200 and a pushing structure 300. The support structure 200 is installed at the bottom of the inner pot 120 of the pot body 110 and is arranged around the outside of the heating plate 130. When the support structure is not subjected to external force, the top of the support structure is higher than the top surface of the heating plate, providing elastic support in the vertical direction. The pushing structure 300 is installed inside the pot body 110 and is driven by the rotating and opening pot lid 140. It is used to push the support structure 200 upward so that the top surface of the support structure 200 is higher than the top surface of the heating plate 130, thus lifting the inner pot 150 upward.

[0031] The aforementioned support mechanism forms a buffer support on the upper outer side of the heating plate to prevent the inner pot from falling and colliding with the heating plate, thus preventing damage to the bottom of the inner pot and the heating plate.

[0032] The push mechanism is driven by the rotating lid, which moves the push support structure upward until the top surface is higher than the top surface of the heating plate, thus lifting the inner pot upward and making the top of the inner pot stand up for easy gripping and placement; the lifting action follows the action of the lid opening, making it easy to operate.

[0033] Furthermore, such as Figure 4 , Figure 5 As shown, the supporting structure 200 includes a support ring 230. The bottom surface of the support ring 230 is fixedly provided with a plurality of first insertion tubes 210 arranged in a circular array around the center, and two second insertion tubes 220. The two second insertion tubes are symmetrically arranged about the central plane of the rotation axis of the pot lid. The bottom of the inner liner 120 is provided with a plurality of third guide holes 121 corresponding to the first insertion tubes 210 and the second insertion tubes 220. The first insertion tubes and the second insertion tubes move vertically along the third guide holes, effectively limiting the movement of the support ring and making it rise and fall smoothly.

[0034] A first spring 240 is installed inside the first insertion tube 210. The bottom end of the first spring 240 is inserted into the third insertion tube 111 on the inner wall of the bottom of the pot body 110. Multiple first springs provide elastic support for the support ring, forming an effective buffer support effect.

[0035] like Figure 2 , Figure 5As shown, a bullseye bearing 250 is installed at the bottom of the second insertion tube 220; the push structure 300 includes two push blocks 311, the top surface of which is inclined, and the position of the push block 311 corresponds to the position of the bullseye bearing 250; when the support ring moves down to be flush with the top surface of the heating plate, the balls of the bullseye bearing abut against the inclined surface of the push block; rotating and opening the pot lid to the preset position can drive the push structure to move, causing the push block to move laterally, lifting the bullseye bearing, thereby lifting the support ring; by setting the push block, the downward movement height of the support ring can be limited, keeping it at the bottom position against the inner pot, which is convenient for subsequently lifting the inner pot; the top of the push block is provided with an inclined surface, which serves as the pushing part, making it easy to convert the lateral movement of the push block into the effect of lifting the support ring upward.

[0036] Furthermore, such as Figure 10 As shown, the rear wall of the pot body 110 is provided with a clamping cavity 112, the top of the clamping cavity is open, and support plates 113 are fixed on both sides of the top of the clamping cavity 112. The rear end of the pot lid 140 is rotatably installed between the two support plates 113 through the first rotating shaft, providing a basic flip-top opening action.

[0037] like Figure 2 , Figure 5 As shown, the push structure 300 includes a pusher 310, a connecting rod 320, and a pusher 330; the pusher 330 is rotatably mounted on the top of the clamping cavity 112 via a second rotating shaft and is connected to the rear end of the pot lid 140 via a transmission connection; the pusher 310 slides close to the bottom inner wall of the pot body 110; the upper part of the connecting rod 320 is rotatably mounted between the two side walls of the clamping cavity 112 via a third rotating shaft; the bottom end of the connecting rod 320 is movably connected to one end of the pusher 310 via a fourth rotating shaft 340; the top end of the connecting rod 320 rests on the moving trajectory of the pusher 331 of the pusher 330; when After the pot lid flips to the preset position, it drives the push rod of the pusher to push the top of the connecting rod, thereby pushing the pusher outward, and then lifting the support ring through the push block. Through the design and cooperation of the pusher, connecting rod and pusher, the reverse rotation of the pot lid is converted into the action of pushing the pusher to move laterally, thereby lifting the support ring upward. In addition, the rotation fulcrum of the connecting rod is limited to the upper position. A short distance of offset at the upper end can achieve a longer distance of offset at the lower end, so as to adapt to the small-amplitude flipping action of the pot lid, and also to meet the requirement of sufficient lateral movement of the pusher at the lower end to achieve the required lifting height of the support ring.

[0038] Furthermore, such as Figure 7As shown, the pusher 330 includes a first support shaft 332, on which two opposing gears 333 are fixedly mounted; the push rod 331 includes an arc strip 3311 and an arc plate 3312 connected together, with both sides of the arc plate 3312 fixed to the inner walls of the two gears 333 respectively, and the arc plate 3312 narrows towards the center from both sides at one counterclockwise end, with the arc strip 3311 connected to the end of the narrowing section; the top of the connecting rod 320 has a strip-shaped opening 321 extending along the length direction, through which the arc strip passes, and the width of the arc strip 3311 matches the width of the strip-shaped opening 321; as Figure 9 , Figure 10 As shown, a support block 141 is fixedly provided at the middle of the rear end of the pot lid 140. The support block 141 rotates between two support plates 113 via a first rotating shaft. A toothed part 142 is provided in the middle of the support block 141, and the toothed part 142 meshes with a gear 333 for transmission. When the pot lid is opened, the support block drives the pusher to rotate. Only when the pot lid is tilted to a preset position, the pusher moves to the top of the pusher link, thereby driving the link to move. More specifically, the pot lid has two stopping positions when it is flipped. The first is the normal opening position, which does not push the support ring to move upward, and is used for normal food storage. The second is the position where the support ring moves upward, which is convenient for taking out and putting in the inner pot. When the pot lid is rotated from the first position to the second position, the toothed part drives the gear to rotate. At this time, the connection between the arc strip and the arc plate will push the upper end of the link, and the link will rotate around the second rotating shaft, thereby pushing the pusher frame below to move laterally, and then pushing the support ring upward through the push block.

[0039] To achieve the above effect, the end face of the support block 141 is further slidably abutted against the inner wall of the support plate 113; the two end faces of the support block 141 are embedded with ball bearings 143, and the inner wall of the support plate 113 is provided with a first locking hole 114 and a second locking hole 115 corresponding to the movement trajectory of the ball bearings 143; when the ball bearings move to the first locking hole, the pot lid swings to an upright, forward tilted state, and the connection between the arc strip and the arc plate moves to the strip-shaped opening position; when the ball bearings move to the second locking hole, the pot lid swings to an upright, rear tilted state, and the pusher presses the connecting rod to the preset position; the rotation locking effect is achieved through the ball bearings, which has a simple structure and is convenient to use and operate;

[0040] Furthermore, the support block has a first circular hole penetrating both ends, and the support plate has a corresponding second circular hole for inserting the first rotating shaft; the two ends of the first circular hole have a first recessed groove, and the end of the second circular hole near the support block has a second recessed groove. The first and second recessed grooves are adapted to the shape of the torsion spring and are used to limit the locking strips at both ends of the torsion spring, so that the torsion spring can assist the lid in popping up, making it easy to open the lid; this elastic force can also be used to provide support for the lid, keeping it in an upward position; it should be noted that the front end of the lid has a fastening groove or fastener, and a fastener or fastening groove is correspondingly set at the front end of the top of the pot body to realize the fastening action, making it easy to close and open the lid. This is the conventional connection and matching method of rice cooker lids, and the specific structure will not be described in detail.

[0041] Furthermore, such as Figure 6 As shown, two symmetrically arranged support rings 322 are fixed at the bottom end of the connecting rod 320, with a gap between the two support rings. The fourth rotating shaft 340 is inserted and installed between the two support rings 322; Figure 8 As shown, the pusher 310 includes two parallel push blocks 311. The inclined surface at the top of the push blocks slopes downward toward the side away from the connecting rod. The two push blocks 311 are connected by a first support bar 312. A second support bar 313 extending toward the connecting rod is fixedly provided in the middle of the first support bar 312. A collar 314 is fixedly provided at the end of the second support bar 313. The collar 314 is sandwiched between two support rings 322. The inner diameter of the collar 314 is larger than the diameter of the fourth rotating shaft 340. The space left for the fourth rotating shaft to swing upward slightly also satisfies the effect of pushing the pusher forward.

[0042] The second frame 313 is provided with a first guide hole 317 that penetrates the bottom surface. The first guide hole extends along the length direction, such as... Figure 2 As shown, at least two guide bolts 360 are inserted through the first guide hole 313, and the bottom end of the guide bolt is installed on the bottom inner wall of the pot body; the bottom surfaces of the push block, the first support bar, and the second support bar are all slidably abutted against the bottom inner wall of the pot body, which can further limit the movement of the entire push frame, prevent it from running off course, and realize the accurate and effective pushing of the push block against the support ring.

[0043] Furthermore, such as Figure 8 , Figure 5As shown, a push plate 315 is fixedly provided on the top surface of the second support bar 313. The push plate is located on the outer side of the first guide hole near the collar. A guide rod 316 is fixedly provided on the top of the side wall of the push plate 315 near the first guide hole. A bracket 116 is provided across the top of the second support bar 313. The two ends of the bracket are installed on the vertical plate of the bottom inner wall of the pot body by bolts. A second guide hole 117 is provided on the bracket 116. The guide rod 316 moves through the second guide hole 117. A second spring 350 is sleeved on the guide rod 316. The second spring is clamped between the bracket and the push plate. This design enables the push structure to have an automatic reset effect. When the pot lid rotates to the position where the ball swings back to the first locking hole, the pusher disengages from the position of pushing the connecting rod. The second spring pushes the pusher back to the initial position.

[0044] The present invention also discloses a rice cooker, including a support mechanism, a pot body, an inner pot, a pot lid, a heating plate, an inner pot, a temperature limiter, a power-off mechanism, a control panel, and other components. It should be noted that, except for the structural components improved to match the support mechanism, the other components are all commonly used structural components of rice cookers, and will not be described in detail.

[0045] 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.
