Description

Technical Field

[0001] This utility model relates to the field of rice cookers, and more specifically, to a sealing ring for the inner lid of a rice cooker. Background Technology

[0002] The sealing ring of a rice cooker is a sealing component primarily used to maintain the airtightness of the inner pot during cooking and heat preservation. During cooking, the sealing ring tightly seals against the edge of the lid and inner pot, preventing steam leakage and ensuring stable pressure inside the pot. This improves heating efficiency, shortens cooking time, and guarantees the quality of the rice. During heat preservation, the sealing ring effectively reduces heat loss, maintains a constant internal temperature, and extends the time the rice is kept warm. Furthermore, the elastic design of the sealing ring cushions the impact of opening and closing the lid, protecting the inner pot's coating from physical damage.

[0003] During the rice cooker's heat preservation phase, to maintain the rice's texture and quality, besides optimizing the heat preservation effect and avoiding frequent reheating, it's also necessary to eliminate the impact of condensation on the rice. During the heat preservation process, the pressure inside the rice cooker decreases, causing some steam to remain inside. This steam easily forms condensation droplets upon contact with the inner lid. If these droplets fall back onto the rice surface, they can cause localized dampness and discoloration, affecting the rice's quality. Existing solutions typically rely on protruding structures on the inner lid to increase the adhesion of condensation and reduce its fall, but this is not very effective, especially as condensation droplets still fall during opening or moving the rice. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a sealing ring for the inner lid of a rice cooker to solve the problem that condensation droplets in the heat preservation section of the existing rice cooker easily fall onto the rice surface.

[0005] The technical solution adopted in this utility model is a sealing ring for the inner lid of a rice cooker, comprising: A ring-shaped, sequentially connected abutment piece, receiving piece, and pressing piece; The abutment piece is used to mate with the inner cover and has a liquid storage cavity that communicates with the outside. The surface of the receiving plate forms a liquid-retaining surface and holds the liquid between the abutting plate and the receiving plate; The liquid storage surface is connected to the liquid storage cavity; The compression sheet is used to fit the inner liner.

[0006] The abutment plate mates with the inner cover to collect condensate, and the liquid storage chamber on the abutment plate is used to temporarily store condensate; the receiving plate forms a liquid storage surface to collect liquid flowing down from the abutment plate; the bottommost pressing plate mates with the inner liner to provide a seal.

[0007] In order to increase the water storage capacity of the abutment piece, the inner edge of the abutment piece is connected to the inner edge of the receiving piece, and a suspension edge extending inward is formed on the inner edge of the abutment piece. The suspended edge is used to cooperate with the inner cover to form an infiltration seam that connects to the liquid storage cavity; The outer edge of the receiving piece is connected to the outer edge of the pressing piece; The inner edge of the pressing sheet is suspended.

[0008] The connection method of the abutment plate, the receiving edge, and the pressing plate makes the sealing ring form an S-shape, making the sealing ring flatter when pressed; the seepage seam is used to guide liquid seepage.

[0009] To enhance the structural strength of the edges, the surface of the abutment piece is provided with, from the outside to the inside, a limiting protrusion and a receiving protrusion in sequence; The inner edge of the suspension edge is provided with a convex edge; The liquid storage cavity is located between the receiving protrusion and the protrusion.

[0010] The limiting ring is used to limit the size of the inner cover, and the receiving ring is used to receive the edge of the inner cover; a recessed space is formed between the ring and the edge, which is the liquid storage cavity, used to store condensate, and the ring is used to prevent the liquid in the liquid storage cavity from overflowing.

[0011] To accelerate liquid penetration, a guide slope is provided on the side of the convex edge near the liquid storage cavity; The bottom of the liquid storage chamber is located in the same horizontal plane and is connected to the lower edge of the guide slope.

[0012] The inclined guide slope allows the liquid to quickly seep into the storage chamber along the curve of the slope. The bottom of the storage chamber is connected to the lower edge of the guide slope, which can prevent the liquid in the storage chamber from overflowing.

[0013] In order to increase the overall liquid storage capacity of the sealing ring, a reserved gap is provided between the abutment piece and the receiving piece, and the reserved gap and the bottom surface of the abutment piece form an open mounting cavity for installing the support member. The outer edge of the receiving piece is suspended downwards so that a gap for liquid storage is left between the liquid storage surface and the mounting cavity.

[0014] The downward drooping outer edge of the receiving plate increases the liquid storage space between the liquid storage surface and the mounting cavity, allowing the receiving plate to hold more liquid from the abutment plate.

[0015] To balance and stabilize the abutment piece and the receiving piece, and to improve the stability of the structure, an annular connecting ring is also included; The upper edge of the connecting ring is connected to the inner edge of the abutment piece, and the lower edge of the connecting ring is connected to the inner edge of the receiving piece. The abutting piece and the receiving piece are parallel to each other; The width of the receiving piece is greater than that of the abutting piece.

[0016] The annular connecting ring is used to maintain the gap between the abutment plate and the receiving plate. The width of the receiving plate is greater than that of the abutment plate, which increases the liquid storage capacity of the receiving plate.

[0017] To improve the support force for liquid, the receiving piece includes: a connected horizontal section and an inclined section; The horizontal section is parallel to the abutting piece and is located inside the inclined section; The width of the horizontal segment is the same as the width of the abutment piece; The inclined segment is higher on the side closer to the horizontal segment and lower on the side farther from the horizontal segment, and forms a crease between the inclined segment and the horizontal segment.

[0018] The horizontal section of the receiving plate is parallel to the abutment plate and is used to store and support the liquid; the inclined section can eliminate some of the downward pull of the pressing plate, making the horizontal section of the receiving plate more stable.

[0019] To aid in positioning and stabilizing the liquid, it also includes: several protrusions extending towards the center; The protrusions are evenly distributed and extend toward the center of the sealing ring through the abutment piece and the receiving piece; The protrusion is provided with a connecting channel that connects the liquid storage cavity and the liquid storage surface.

[0020] The boss is used to assist in positioning during installation, and it can also store liquid. The liquid in the storage chamber flows to the storage surface through the connecting channel on the boss, realizing liquid transfer and preventing excessive liquid from dripping into the inner liner.

[0021] To accelerate flow and increase local liquid volume, the protrusion forms a local expansion of the liquid storage cavity; The connecting channel forms an oblong inlet at the bottom of the liquid storage chamber.

[0022] The boss expands the range of the liquid storage chamber and increases the liquid storage capacity, while the waist-shaped inlet hole allows the liquid in the liquid storage chamber to flow out quickly.

[0023] In order to control the liquid from entering the receiving plate, the receiving plate is provided with a sealing structure for sealing the connection channel; The position and number of the enclosed structures are matched one-to-one with the connecting channels; The cross-section of the closed structure is larger than that of the connecting channel and forms a pressure-bearing surface on the bottom surface of the receiving piece, so that under the action of gas pressure from below, the pressure-bearing surface bulges to form a closure on one side of the connecting channel.

[0024] The closed structure is used to seal the connection channel, preventing liquid from entering the receiving plate and controlling the flow of liquid on the sealing ring.

[0025] Compared with the prior art, the beneficial effects of this utility model are mainly reflected in the following aspects: 1. Use a sealing ring to store condensate and remove it promptly to prevent condensate from flowing back into the inner tank. The liquid storage chamber on the abutment plate collects the condensate flowing down from the inner cover. The condensate in the liquid storage chamber flows to the receiving plate of the next layer, preventing excessive condensate on the abutment plate, increasing the liquid storage capacity of the entire sealing ring, and also preventing the condensate on the abutment plate from falling back into the inner pot, causing the rice to become damp and discolored in some areas.

[0026] 2. The strength and functionality of the sealing ring have been enhanced.

[0027] A limiting protrusion, a receiving protrusion, and a boss are sequentially set on the abutment piece to enhance the strength of the edge structure of the abutment piece; by setting a connecting ring between the inner edge of the abutment piece and the inner edge of the receiving piece, the abutment piece and the receiving piece are made parallel to each other, balancing and stabilizing the abutment piece and the receiving piece, thus improving the stability of the sealing ring structure; the receiving piece is set as a horizontal section and an inclined section, with the inclined section eliminating part of the downward pull of the pressing piece, making the horizontal section more stable.

[0028] 3. Increase the liquid storage capacity of the sealing ring. The inner edge of the abutment plate extends inward to form a suspended edge, allowing the abutment plate to hold more liquid. A reserved gap is provided between the abutment plate and the receiving plate, and the outer edge of the receiving plate hangs down, leaving a liquid storage space between the liquid storage surface and the mounting cavity, allowing the receiving plate to hold more liquid from the abutment plate. The boss on the sealing ring forms a local expansion of the liquid storage cavity, which increases the range of the liquid storage cavity and the amount of liquid stored in the cavity.

Detailed Implementation

[0040] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0041] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a sealing ring for the inner lid of a rice cooker, comprising: The ring-shaped and sequentially connected abutment piece 100, receiving piece 200, and pressing piece 300; The abutment piece 100 is used to cooperate with the inner cover and has a liquid storage cavity 110 that communicates with the outside. The surface of the receiving piece 200 forms a liquid storage surface 210 and supports the liquid between the abutting piece 100 and the receiving piece 200; The liquid storage surface 210 is connected to the liquid storage cavity 110; The compression sheet 300 is used to fit with the inner liner.

[0042] A sealing ring is formed by the sequentially connected abutment piece 100, receiving piece 200, and pressing piece 300, which serves to seal the pot body and collect and guide condensate. The condensate flowing down from the inner cover wall collects in the liquid storage cavity 110 on the abutment piece 100. When there is a certain amount of condensate in the liquid storage cavity 110, the condensate flows down to the liquid storage surface 210 on the receiving piece 200, increasing the liquid storage capacity of the sealing ring. The uppermost abutment piece 100 cooperates with the inner cover, and the lowermost pressing piece 300 cooperates with the inner liner, together serving to seal the pot body.

[0043] like Figure 1 As shown in Figure 5, the inner edge 150 of the abutment piece is connected to the inner edge 240 of the receiving piece, and an inwardly extending suspension edge 120 is formed on the inner edge 150 of the abutment piece. The suspended edge 120 is used to cooperate with the inner cover to form an infiltration slit that connects to the liquid storage cavity 110; The outer edge 250 of the receiving piece is connected to the outer edge 310 of the pressing piece; The inner edge 320 of the press sheet is suspended.

[0044] The abutment piece 100, the receiving piece 200, and the pressing piece 300 are connected in the above manner to form an S-shaped sealing ring, so that the thickness of both ends of the sealing ring is equal, making it more flat and stable when it fits with the inner cover and the inner liner during use. The suspension edge 120 on the abutment piece 100 forms a seepage seam with the inner cover, which can guide the condensate on the inner cover into the liquid storage chamber 110.

[0045] like Figure 1-4 As shown, the surface of the abutment piece 100 is provided with, from the outside to the inside, a limiting protrusion 130 and a receiving protrusion 140 in sequence; The inner edge of the suspension edge 120 is provided with a protruding edge 122; The liquid storage cavity 110 is disposed between the receiving protrusion 140 and the protrusion 122.

[0046] When the abutment piece 100 mates with the inner cover, the limiting protrusion 130 restricts the inner cover to prevent displacement; the receiving protrusion 140 receives the inner cover. When the abutment piece 100 receives condensate, the condensate flows into the liquid storage chamber 110. When a certain amount of condensate is stored in the liquid storage chamber 110, the suspension edge 120 becomes heavier and deforms, drooping slightly, making the liquid storage chamber 110 larger and able to receive more condensate. The protrusion 122 can prevent the condensate in the liquid storage chamber 110 from falling back into the inner liner under the action of gravity.

[0047] like Figure 2-4 As shown, the convex edge 120 has a guide slope 121 on the side near the liquid storage cavity 110; The bottom of the liquid storage cavity 110 is located in the same horizontal plane and is connected to the lower edge of the guide slope 121.

[0048] The suspension edge 122 forms a seepage seam with the inner cover. When the condensate seeps in, the guide slope 121 on the protrusion accelerates the flow of condensate into the liquid storage chamber 110. Since the lower edge of the guide slope 121 is connected to the bottom of the liquid storage chamber 110, that is, the upper edge of the guide slope 121 is far away from the liquid storage chamber 110, it can effectively prevent the condensate in the liquid storage chamber 110 from overflowing.

[0049] like Figure 1-8 As shown, a reserved gap is provided between the abutment piece 100 and the receiving piece 200, and the reserved gap and the bottom surface of the abutment piece 100 form an open mounting cavity 410 for installing the support member. The outer edge 250 of the receiving piece is suspended downwards so that a liquid storage gap is left between the liquid storage surface 210 and the mounting cavity 410.

[0050] The mounting cavity 410 allows the support to be installed between the abutment piece 100 and the receiving piece 200. The space between the receiving piece 200 and the mounting cavity 410 is the size of the liquid storage surface 210. When the liquid storage surface 210 receives condensate from the abutment piece 100, the gap between the receiving piece 200 and the mounting cavity 410 increases, which means that the capacity of the liquid storage surface 210 increases, thus increasing the liquid storage capacity of the receiving piece 200.

[0051] like Figure 1-5 As shown in Figure 8, it also includes: an annular connecting ring 400; The upper edge of the connecting ring 400 is connected to the inner edge 150 of the abutment piece, and the lower edge of the connecting ring 400 is connected to the inner edge 240 of the receiving piece. The abutting piece 100 and the receiving piece 200 are parallel to each other; The width of the receiving piece 200 is greater than that of the abutting piece 100.

[0052] The annular connecting ring 400 is positioned between the inner edge 150 of the abutment piece and the inner edge 240 of the receiving piece, maintaining a certain distance between the abutment piece 100 and the receiving piece 200, making the abutment piece 100 and the receiving piece 200 more stable; under the action of water tension, the wider receiving piece 200 makes the liquid storage surface 210 larger, increasing the liquid storage capacity of the liquid storage surface 210.

[0053] like Figure 1 and 9 As shown, the receiving piece 200 includes: a connected horizontal section 220 and an inclined section 230; The horizontal segment 220 is parallel to the abutting piece 100 and is located inside the inclined segment 230; The width of the horizontal segment 220 is the same as the width of the abutment piece 100; The inclined segment 230 is higher on the side closer to the horizontal segment 220 and lower on the side farther from the horizontal segment 220, and forms a crease between it and the horizontal segment 220.

[0054] When the condensate on the contact plate 100 flows to the receiving plate 200, it flows onto the horizontal section 220 of the receiving plate 200 and spreads along the horizontal section 220 of the receiving plate 200. The inclined section 230 of the receiving plate 200 eliminates part of the downward pull of the pressing plate 300, reduces the inclination of the entire receiving plate 200, and allows the horizontal section 220 to better support and store the condensate.

[0055] like Figure 1-2 As shown in Figure 6, it also includes: a plurality of protrusions 170 extending toward the center; The bosses 170 are evenly distributed and extend toward the center of the sealing ring through the abutment piece 100 and the receiving piece 200; The boss 170 is provided with a connecting channel 171 that connects the liquid storage cavity 110 and the liquid storage surface 210.

[0056] Since the boss 170 is formed by the abutment piece 100 and the receiving piece 200 extending towards the center of the sealing ring, the boss 170 is significantly different from other parts of the abutment piece 100. During installation, the boss 170 can be positioned and installed according to its location. Furthermore, since the boss 170 has a certain thickness, it improves the structural stability of the abutment piece 100 and the receiving piece 200. The condensate in the liquid storage chamber 110 flows into the liquid storage surface 210 on the receiving piece 200 through the connecting channel 171 on the boss 170, thereby transferring the condensate and preventing excessive condensate in the liquid storage chamber 110 from falling back into the inner liner.

[0057] like Figure 2 As shown in Figure 7, the boss 170 forms a partial expansion of the liquid storage cavity 110; The connecting channel 171 forms an oblong inlet hole at the bottom of the liquid storage chamber 110.

[0058] Since the boss 170 is formed by the inward extension of the abutment piece 100 and the receiving piece 200, a liquid storage cavity 110 is also provided on the boss 170. The shape of the boss 170 increases the area of ​​the liquid storage cavity 110, making the capacity of the liquid storage cavity 110 larger. The condensate in the liquid storage cavity 110 flows into the connecting channel 171 through the waist-shaped liquid inlet hole, realizing the transfer of condensate in the liquid storage cavity 110.

[0059] like Figure 1-2 As shown in Figures 7 and 10, the receiving piece 200 is provided with a closing structure 260 for closing the connecting channel 171; The position and number of the closed structures 260 are matched one-to-one with the connecting channels 171; The cross-section of the closed structure 260 is larger than that of the connecting channel 171 and a pressure-bearing surface is formed on the bottom surface of the receiving piece 200, so that under the action of gas pressure from bottom to top, a closure is formed on one side of the connecting channel 171 on the pressure-bearing surface.

[0060] When there is a lot of steam in the pot, the receiving plate 200 rises under the action of the steam, and the sealing structure 260 rises to seal the connecting channel 171. The condensate on the receiving plate 100 cannot flow into the liquid storage surface 210 through the connecting channel 171, thus forming an adaptive control of the liquid collection stage.

[0061] Example 2 like Figure 1 and 5 As shown, this embodiment is a sealing ring for the inner lid of a rice cooker. The sealing ring is formed by connecting the abutment piece 100, the receiving piece 200 and the pressing piece 300 in sequence. The inner edge 150 of the abutment piece is connected to the inner edge 240 of the receiving piece, the outer edge 250 of the receiving piece is connected to the outer edge 310 of the pressing piece, and the inner edge 320 of the pressing piece is suspended, so that the sealing ring forms an S-shaped structure with equal thickness on the inner and outer sides, making it flatter and more stable when pressed.

[0062] like Figure 1-5 As shown, an inwardly extending suspension edge 120 is formed on the inner edge 150 of the abutment piece, and the suspension edge 120 can deform under the action of force; the abutment piece 100 is provided with a limiting protrusion ring 130 and a receiving protrusion ring 140 from the outside to the inside. When it is engaged with the inner cover, the limiting protrusion ring 130 restricts the inner cover, and the receiving protrusion ring 140 is used to receive the inner cover. The receiving protrusion ring 140 is slightly lower than the limiting protrusion ring 130 to prevent the inner cover from shifting and also plays a certain sealing role; the inner edge of the suspension edge 120 is provided with a protrusion edge 122, and the space between the receiving protrusion ring 140 and the protrusion edge 122 is a liquid storage cavity 110 for receiving condensate. A guide slope 121 is provided on the side of the protrusion edge 122 near the liquid storage cavity 110 to guide the condensate into the liquid storage cavity 110. When the sealing ring is fitted with the inner cover, the suspension edge 120 is slightly raised under the upward action of steam, and the distance between the suspension edge 120 and the inner cover is reduced, forming a seepage gap. The condensate flows from the seepage gap along the guide slope 121 into the liquid storage chamber 110, thereby realizing the collection of condensate.

[0063] like Figure 1-7As shown, the abutment piece 100 and the receiving piece 200 extend inward to form several protrusions 170. The width of the receiving protrusion ring 140 and the protrusion edge 122 on the protrusion 170 is the same as that of other parts on the abutment piece 100. Therefore, the amount of solution in the liquid storage cavity 110 on the protrusion 170 is greater than that in the non-protrusion positions on the abutment piece 100. The protrusion 170 is also provided with a connecting channel 171. The connecting channel 171 has a flat liquid guide hole 172 at the bottom of the liquid storage cavity 110. The liquid guide hole 172 is waist-shaped and is used to drain the condensate in the liquid storage cavity 110. When a certain amount of condensate is stored in the liquid storage cavity 110, the condensate flows into the connecting channel 171 through the liquid inlet hole and into the receiving piece 200 below through the connecting channel 171, realizing the transfer of condensate and increasing the sealing ring's ability to receive condensate.

[0064] like Figure 1-9 As shown, a connecting ring 400 is provided between the inner edge 240 of the receiving piece and the inner edge 150 of the abutment piece for support, so that there is a gap between the receiving piece 200 and the abutment piece 100. The receiving piece 200 is divided into a horizontal section 220 and an inclined section 230. One end of the horizontal section 220 is connected to the inner edge 240 of the receiving piece, and the other end is connected to the inclined section 230. The other end of the inclined section 230 is connected to the outer edge 250 of the receiving piece. The horizontal section 220 of the receiving piece 200 is parallel to the bottom surface of the abutment piece 100. Under the action of the connecting ring 400, an open mounting cavity 410 is formed between the horizontal section 220 and the abutment piece 100. The surface of the receiving plate 200 is a liquid storage surface 210, which receives condensate from the liquid storage chamber 110. The condensate flows from the connecting channel 171 to the liquid storage surface 210 of the receiving plate 200. The receiving plate 200 of the horizontal section 220 provides support, and the receiving plate 200 of the inclined section 230 eliminates part of the downward pull of the pressing plate 300, reduces the inclination of the horizontal section 220, and improves the support force of the horizontal section 220. When it is necessary to fix the support sealing ring, the support can be installed in the mounting cavity 410 between the abutment plate 100 and the receiving plate 200.

[0065] A sealing structure 260 is provided at the position corresponding to the receiving plate 200 and the connecting channel 171. When there is a lot of steam, it rises and drives the receiving plate 200 to rise together. The sealing structure 260 closes the connecting channel 171, preventing the condensate in the liquid storage chamber 110 from flowing to the liquid storage surface 210 through the connecting channel 171, thereby controlling the closure of the connecting channel 171. When there is less steam, the receiving plate 200 cannot rise under the action of steam. The sealing structure 260 separates from the connecting channel 171, and the connecting channel 171 opens. The condensate in the liquid storage chamber 110 flows into the connecting channel 171 through the liquid guide hole 172 and then flows into the liquid storage surface 210, realizing the adaptive control of the condensate transfer and collection stage.
