Description

Technical Field

[0001] This utility model relates to the field of household appliances, and more specifically, to an inner lid for a rice cooker with liquid collection. Background Technology

[0002] An electric rice cooker is a modern cooking appliance capable of steaming, boiling, stewing, simmering, and braising, making it an essential kitchen appliance in modern households. Its convenient and efficient rice-cooking function has earned it widespread popularity. Its core components consist of an inner pot, a heating plate, and a temperature control system. The heating plate converts electrical energy into heat energy, while the temperature controller precisely monitors the temperature, ensuring that the rice enters a keep-warm state after boiling, preventing undercooked rice or burnt rice. Whether for daily meals or family gatherings, the electric rice cooker, with its time-saving and labor-saving features, has become a powerful assistant in simplifying the cooking process.

[0003] When a rice cooker is working, the high-temperature steam inside rises and comes into contact with the cooler lid, especially the inside and edges. The steam condenses into liquid water upon contact with the cool lid, forming condensate. If left untreated, this condensate may drip back into the rice through the lid's seams, causing some areas of the rice to become mushy; or it may drip from the edges of the cooker, soiling the countertop. Current rice cookers typically have a collection box on one side of the cooker. After opening the lid, the condensate drips into the pot along the edge and is then guided to the collection box. However, this method only guides the condensate from the lid's edge to the collection box after the lid is opened. During the cooking process, the water storage area is limited to the edge of the lid, resulting in a significant amount of condensate still dripping into the food. Furthermore, the guidance effect from the edge to the collection box after opening the lid is limited, making the condensate collection ineffective. Utility Model Content

[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide an inner lid for a rice cooker with liquid collection, which improves the collection effect of condensate in the rice cooker.

[0005] The technical solution adopted by this utility model is to provide an inner lid for a rice cooker with liquid collection, comprising: a lid body, a sealing ring, and an annular clamping outer frame. The inner side of the clamping outer frame is provided with a clamping cavity for clamping the outer edge of the lid body. The sealing ring is installed between the clamping outer frame and the lid body. The characteristic feature is that a water storage structure is provided on one side of the clamping outer frame, and the sealing ring and the lid body form a water receiving cavity, and the water storage structure is connected to the water receiving cavity.

[0006] In this technical solution, the clamping cavity holds and fixes the lid, and the sealing ring improves the sealing performance to maintain a specific pressure environment inside the rice cooker and prevents steam and moisture from escaping from the edges. When the steam generated inside the rice cooker rises to the lid and generates condensate, the condensate flows through the water receiving cavity to the water storage structure for storage. This greatly increases the water storage space of the inner lid in a horizontal state. The rice cooker can collect condensate while cooking without having to open the lid to drain and collect it, greatly improving the condensate collection effect and preventing excessive condensate from dripping back into the food in the pot and affecting the taste. It also prevents condensate from dripping into the boiling area inside the pot and causing foaming and splashing, thus improving the safety of cooking with the rice cooker.

[0007] Furthermore, the water storage structure includes: an open cavity communicating with the outside, and side cavities disposed on both sides of the open cavity; the clamping frame is provided with a liquid channel communicating with the water receiving cavity and the side surface of the clamping frame; the clamping frame is provided with a water inlet channel communicating with the side surface of the clamping frame and the side cavity.

[0008] Furthermore, the open cavity forms a horizontally oriented open opening on the side surface of the clamping frame; both ends of the open cavity are respectively connected to the two side cavities, and a connecting hole is formed on the side wall of the side cavity connected to the open cavity near the back side of the clamping frame.

[0010] Furthermore, the bottom of the open cavity is provided with a liquid-receiving surface, which is an inclined surface; the side of the liquid-receiving surface closer to the clamping frame is higher, and the side farther from the clamping frame is lower.

[0011] Furthermore, one side of the open cavity and the side cavity are connected to the back side of the clamping frame, and the other side extends in the opposite direction to protrude from the front side of the clamping frame.

[0012] Furthermore, the water inlet channel includes a vertical section, a horizontal section, and an inclined section connected in sequence; the vertical section forms a first opening on the side of the clamping frame near the side cavity, and the side of the first opening extends to the back side of the clamping frame; the top of the inclined section is open, forming a second opening inside the clamping frame that is separated from the water receiving cavity; the bottom of the horizontal section is open, forming a third opening on the front side of the clamping frame.

[0013] Furthermore, the clamping frame is detachably connected to the water storage structure; the side of the clamping frame near the water storage structure includes: an open liquid guiding cavity on one side, and liquid guiding pipes disposed on both sides of the liquid guiding cavity; the two sides of the liquid guiding cavity are connected to the two liquid guiding pipes; the liquid guiding pipes are sleeved and connected to the side cavity; an inner wall of the open cavity closes the open surface of the liquid guiding cavity.

[0014] Furthermore, the liquid guide tube has a snap-fit ​​protrusion on its side, and the side wall of the water storage structure has a snap-fit ​​position that cooperates with the snap-fit ​​protrusion; the liquid guide tube is provided with an elastic seal, and the elastic seal makes the liquid guide tube and the side cavity form an interference fit.

[0015] Furthermore, the water inlet channel connects the liquid guiding cavity and the side of the clamping frame; the water inlet channel and the water receiving cavity are provided with a partition protrusion ring; the water inlet channel includes a first channel symmetrically arranged and close to the liquid guiding tube, and a second channel arranged between the two first channels and at the lowest position when the clamping frame is vertical.

[0017] (1) This utility model greatly increases the water storage space of the inner lid in the horizontal state. The rice cooker can collect condensate while cooking, without having to open the lid to drain and collect the condensate. This improves the condensate collection effect, avoids excessive condensate from falling back into the food in the pot and affecting the taste, and also prevents condensate from dripping into the boiling area of ​​the pot and causing foam splashing, thus improving the safety of cooking with the rice cooker.

[0018] (2) By setting up the water inlet channel and the liquid channel, this utility model guides the condensate to flow to the water storage structure, thereby improving the condensate collection speed. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] Example 1

[0034] refer to Figure 1 and Figure 2This embodiment provides an inner lid for a rice cooker with liquid collection, comprising: a lid body 100, a sealing ring 200, and an annular clamping outer frame 300. The clamping outer frame 300 has a clamping cavity on its inner side, which is used to clamp the outer edge of the lid body 100. The sealing ring 200 is installed between the clamping outer frame 300 and the lid body 100. A water storage structure 400 is provided on one side of the clamping outer frame 300. The sealing ring 200 and the lid body 100 form a water receiving cavity 500, and the water storage structure 400 communicates with the water receiving cavity 500. Specifically, the clamping outer frame 300 includes an outer frame body 310 and a clamping ring 320, which are detachably connected to the body to form the clamping outer frame 300.

[0035] In this technical solution, the clamping cavity holds and fixes the lid 100, and the sealing ring 200 improves the sealing performance to maintain a specific pressure environment inside the rice cooker and prevents steam and moisture from escaping from the edges. When the steam generated inside the rice cooker rises to the lid 100 and generates condensate, the condensate flows through the water receiving cavity 500 to the water storage structure 400 for storage. This greatly increases the water storage space of the inner lid in a horizontal state. The rice cooker can collect condensate while cooking without having to open the lid to drain and collect it, which greatly improves the condensate collection effect and prevents excessive condensate from dripping back into the food in the pot and affecting the taste. It also prevents condensate from dripping into the boiling area inside the pot and causing foaming and splashing, thus improving the safety of cooking with the rice cooker.

[0036] refer to Figure 3 and Figures 4 to 8 Furthermore, the water storage structure 400 includes: an open cavity 410 communicating with the outside, and side cavities 420 disposed on both sides of the open cavity 410; the clamping frame 300 is provided with a liquid channel 700 communicating with the water receiving cavity 500 and the side surface of the clamping frame 300; the clamping frame 300 is provided with a water inlet channel 600 communicating with the side surface of the clamping frame 300 and the side cavity 420.

[0037] In this technical solution, the "external" refers to the side cavity 420. The open cavity 410 is connected to the external, which can be understood as the open cavity 410 being connected to the space inside the pot. When the inner lid is opened, the entire inner lid is vertical, and the condensate on the lid can quickly flow back to the open cavity 410 for collection, preventing it from dripping onto the outside of the rice cooker and contaminating the tabletop, and also preventing it from dripping into the food.

[0038] The condensate in the water receiving chamber 500 enters the side cavity 420 sequentially through the liquid channel 700 and the water inlet channel 600. The side facing the outer frame 300 refers to the side facing the inner liner of the pot. The water inlet channel 600 on the side of the outer frame 300 not only facilitates the flow of liquid in the water receiving chamber 500, but also allows some of the liquid splashed out during boiling inside the pot to enter the side cavity 420 through this water inlet channel 600, preventing overflow.

[0039] For example, on the side of the clamping frame 300, the 200 and the clamping frame 300 form a water-holding cavity 800. The liquid channel 700 connects to the water-holding cavity 800 of the water-connecting cavity 500, and the water inlet channel 600 connects the water-holding cavity 800 and the side cavity 420. The bottom of the water-holding cavity 800 may have an opening connecting to the inner liner of the pot, or it may be closed.

[0040] refer to Figure 3 and Figure 4 Furthermore, the open cavity 410 forms a horizontally oriented open opening on the side surface of the clamping frame 300; the two ends of the open cavity 410 are respectively connected to the two side cavities 420, and a connecting hole 430 is formed on the side wall of the side cavity 420 connected to the open cavity 410 near the back side of the clamping frame 300.

[0041] In this technical solution, the opening is horizontally positioned, so when the lid is opened, the opening of the open cavity 410 faces vertically upwards, which better catches the condensate flowing down the lid and prevents it from flowing into the food. The connection between the side cavity 420 and the open cavity 410 allows liquid in the open cavity 410 to flow into the side cavity 420, preventing the open cavity 410 from overflowing and flowing back into the food. The connecting hole 430 is located near the back side; when the lid is opened, as the condensate in the open cavity 410 flows through the connecting hole 430 into the side cavity 420, the liquid flows away from the food inside the pot, further preventing condensate from flowing into the food.

[0042] Furthermore, the bottom of the open cavity 410 is provided with a liquid-receiving surface 411, which is an arc surface; the two ends of the liquid-receiving surface 411 are respectively connected to the two side cavities 420; the middle part of the liquid-receiving surface 411 is raised so that the middle part is higher than the two sides.

[0043] In this technical solution, the central part of the liquid-receiving surface 411 is higher than the sides, which guides the liquid to the side cavities 420 on both sides, accelerating the distribution and flow of the liquid and preventing excessive liquid from overflowing into the pot from the open cavities 410. The arc-shaped design of the liquid-receiving surface 411 can avoid cleaning dead corners.

[0044] refer to Figure 3Furthermore, the bottom of the open cavity 410 is provided with a liquid-receiving surface 411, which is an inclined surface; the side of the liquid-receiving surface 411 closest to the clamping frame 300 is high, and the side away from the clamping frame 300 is low.

[0045] In this technical solution, after the lid is opened, a large amount of condensate will flow into the open cavity 410. The inclined design of the liquid receiving surface 411 causes the liquid in the open cavity 410 to converge away from the pot body after the lid is opened, thus preventing the condensate from overflowing and flowing into the pot body.

[0046] refer to Figure 12 Furthermore, one side of the open cavity 410 and the side cavity 420 are connected to the back side of the clamping frame 300, and the other side extends in the opposite direction to protrude from the front side of the clamping frame 300.

[0047] In this technical solution, the protruding design of the open cavity 410 and the side cavity 420 increases the volume of the water storage structure 400, thereby increasing the water storage capacity and effectively preventing excessive condensate from overflowing the water storage structure 400 and dripping into the pot. Furthermore, since there is a gap between the side of the clamping frame 300 and the inner pot even when the lid is closed, setting the protrusion direction of the open cavity 410 and the side cavity 420 towards the side does not affect the overall volume of the rice cooker, improving space utilization. Additionally, because the cavity protrudes towards the side, it extends downwards when the lid is closed, allowing condensate to flow into the cavity under gravity, which is beneficial for water storage.

[0048] refer to Figures 8 to 11 Furthermore, the water inlet channel 600 includes a vertical section 610, a horizontal section 630, and an inclined section 620 connected in sequence; the vertical section 610 forms a first opening 611 on the side of the clamping frame 300 near the side cavity 420, and the side of the first opening 611 extends to the back side of the clamping frame 300; the top of the inclined section 620 is open, forming a second opening 621 in the clamping frame 300 that is separated from the water receiving cavity 500; the bottom of the horizontal section 630 is open, forming a third opening 631 on the front side of the clamping frame 300.

[0049] In this technical solution, after the condensate enters the side of the clamping frame 300, it passes sequentially through the horizontal section 630, the inclined section 620, and the vertical section 610 before entering the side cavity 420. The side of the first opening 611 extending to the back side of the clamping frame 300 balances the internal and external pressures of the water inlet channel 600, facilitating smooth liquid flow within the water inlet channel 600. The second opening 621 is separated from the water receiving cavity 500 to prevent liquid from the water inlet channel 600 from flowing back into the water receiving cavity 500. Preferably, the third opening 631 is completely open at the bottom, which increases the liquid inflow rate and accelerates the liquid distribution and unblocking speed.

[0050] For example, the inclined section 620 gradually slopes downwards from the back side to the front side of the clamping frame 300. When liquid enters the water inlet channel 600, it flows upwards. This allows the liquid on the front side of the clamping frame 300 to accumulate to a certain level before the side cavity 420 is automatically activated, allowing the liquid to flow into the side cavity 420 for storage. Thus, when the amount of condensate is small, only the water receiving cavity 500 and the front side of the clamping frame 300 need to be used for water collection, reducing the cleaning process of the side cavity 420 and making it easier for the user to clean.

[0051] refer to Figure 5 Furthermore, the clamping frame 300 is detachably connected to the water storage structure 400; the side of the clamping frame 300 near the water storage structure 400 includes: a liquid guiding cavity 440 open on one side, and liquid guiding pipes 450 disposed on both sides of the liquid guiding cavity 440; the two sides of the liquid guiding cavity 440 are connected to the two liquid guiding pipes 450; the liquid guiding pipes 450 are sleeved and connected to the side cavity 420; an inner sidewall of the open cavity 410 closes the open surface of the liquid guiding cavity 440.

[0052] In this technical solution, the water storage structure 400 is detachably connected, allowing users to easily remove it for thorough cleaning and improving cleaning convenience. The liquid guiding cavity 440 further increases the liquid storage volume and its open design facilitates user cleaning. The liquid guiding pipe 450 is sleeved with and seals the opening of the side cavity 420, while maintaining communication. The liquid guiding cavity 440 connects to the liquid guiding pipe 450, thus connecting to the interior of the side cavity 420. Liquid flows out from the water inlet channel 600 and enters the liquid guiding cavity 440, then flows from the liquid guiding cavity 440 into the side cavity 420. The liquid guiding pipe 450 connects the clamping frame 300 and the water storage structure 400, allowing liquid collected from the clamping frame 300 to smoothly enter the water storage structure 400 for storage. The inner wall of the open cavity 410 closes the open surface of the liquid guiding cavity 440, so that during the cooking process of the rice cooker, the liquid flowing through the liquid guiding cavity 440 will not overflow and affect other structural components of the rice cooker, ensuring the centralized collection of liquids such as condensate and making it easy to clean.

[0053] refer to Figure 5 Furthermore, the liquid guide tube 450 is provided with a snap-fit ​​protrusion 451 on its side, and the water storage structure 400 is provided with a snap-fit ​​position on its side wall that cooperates with the snap-fit ​​protrusion 451; the liquid guide tube 450 is provided with an elastic seal and the elastic seal makes the liquid guide tube 450 and the side cavity 420 form an interference connection.

[0054] In this technical solution, the liquid guide tube 450 and the water storage structure 400 can be quickly fixed and disassembled by snap-fit ​​connection, which is convenient for operation. In addition, with the setting of elastic sealing element, the two are not easy to separate after connection, and have high stability.

[0055] For example, the liquid guide tube 450 is provided with an annular recess, and the elastic sealing member is sleeved on the annular recess, thus forming a stable connection with the liquid guide tube 450 and not easily detached.

[0056] refer to Figure 5 and Figure 9 Furthermore, the water inlet channel 600 connects the liquid guiding cavity 440 and the side of the clamping outer frame 300; the water inlet channel 600 and the water receiving cavity 500 are provided with a partition protrusion 510; the water inlet channel 600 includes a first channel 640 symmetrically arranged and close to the liquid guiding tube 450, and a second channel 650 arranged between the two first channels 640 and in the lowest position when the clamping outer frame 300 is vertical.

[0057] In this technical solution, the arrangement of multiple water inlet channels 600 allows liquid at different positions of the clamping frame 300 to be guided and collected, which is beneficial for the rapid drainage of liquid. When the cover is open, the clamping frame 300 is in a vertical position, and liquids such as condensate flow downwards. The second channel 650 is located at the lowest position, which helps to collect more liquid into the water storage structure 400.
