Technical Field

[0001] This utility model relates to the field of rice cooker technology, specifically to a rice cooker with a removable and washable lid. Background Technology

[0002] An electric rice cooker, also known as an electric pot or rice cooker, is a high-efficiency cooking appliance that converts electrical energy into heat energy to perform various operations such as steaming, boiling, stewing, and simmering food. Its core function is to automatically complete the processes of heating, boiling, and simmering rice through precise temperature control.

[0003] A search revealed a Chinese patent for a rice cooker with a detachable lid, publication number CN219578727U. The patent includes a pot body assembly and a lid assembly, with the lid assembly being detachably mounted on the pot body assembly. The key feature is that the pot body assembly has a support hole, and the lid assembly has a support foot corresponding to the support hole.

[0004] The above-mentioned device has a support hole on the pot body assembly and a support foot on the pot lid assembly. When the user removes the pot lid assembly, it can be vertically inserted into the support hole of the pot body assembly. The operation is simple and convenient, and does not take up table space. The main function of the pot lid clamping column and the pot lid clamping wheel is to press the pot lid assembly and the pot body assembly together, so that the rice cooker does not leak steam when it is working. The structure is simple and the operation is convenient.

[0005] However, its structure is relatively simple. The lid and the pot body are only sealed by mechanical pressing, which has a poor sealing effect. When cooking porridge in a rice cooker, there may be leakage. Although the lid can be removed as a whole, the various components are still connected as one piece, making it difficult to disassemble and clean, resulting in poor performance. Utility Model Content

[0006] The purpose of this invention is to provide a rice cooker with a removable and washable lid, which can effectively solve the problems in the background art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 A rice cooker with a removable and washable lid includes a rice cooker body 1, an inner pot 2 inside the rice cooker body 1, a control panel 3 at the center of the front end of the rice cooker body 1, a lid 4 hinged to one side of the top of the rice cooker body 1, and a disassembly and washing component on the side of the lid 4 near the rice cooker body 1.

[0025] See Figure 2 and Figure 3Furthermore, the disassembly and cleaning assembly includes an anti-detachment ring plate 5, a sealing pressure plate 6, and a sealing gasket 11. A handle is fixedly installed at the center of the side of the lid 4 away from the rice cooker body 1. A fixing rod 7 is fixedly installed at the center of the side of the lid 4 away from the handle. The sealing pressure plate 6 is slidably installed on the outer ring of the fixing rod 7. The anti-detachment ring plate 5 is installed on the outer ring of the lid 4 away from the handle by fixing bolts, and the top of the anti-detachment ring plate 5 is in contact with the bottom surface of the sealing pressure plate 6 near the outer ring. The contact between the anti-detachment ring plate 5 and the sealing pressure plate 6 prevents the sealing pressure plate 6 from detaching from the lid 4. The sealing pressure plate 6 and... Several clamping springs 12 are provided between the opposite surfaces of the pot lid 4. The clamping springs 12 are fixedly connected to the pot lid 4, and the bottom end of the clamping spring 12 abuts against the top surface of the sealing pressure plate 6. The elastic potential energy of the clamping spring 12 is used to push the sealing pressure plate 6 down. The inner ring of the sealing gasket 11 fits with the outer ring of the sealing block plate 8. The outer ring of the sealing block plate 8 is adapted to match the inner diameter of the inner pot 2. Pressure relief holes 13 are provided on both sides of the sealing block plate 8, the sealing pressure plate 6, and the pot lid 4 at the rear position. A pressure relief valve adapted to the pressure relief holes 13 is provided on the side of the pot lid 4 away from the rice cooker body 1.

[0026] Specifically, because the sealing pressure plate 6 and the sealing plug plate 8 are installed on the bottom surface of the pot lid 4 through multiple components, and the size of the sealing plug plate 8 is adapted to match the inner diameter of the inner pot 2, when the pot lid 4 is placed on the rice cooker body 1 during the cooking process, the sealing plug plate 8 will be inserted into the inner pot 2, and the sealing pressure plate 6 will be placed on the top surface of the inner pot 2. At this time, multiple concave and convex sealing structures can be formed to improve the sealing effect. Meanwhile, the sealing pressure plate 6 is movably installed on the pot lid 4, and the bottom surface of the sealing pressure plate 6 is provided with a sealing gasket 11, and the sealing ring 10 is fitted on the outer ring of the sealing plug plate 8, which can effectively reduce the gap at the joint. At the same time, the top of the sealing pressure plate 6 abuts against the clamping spring 12. The elastic potential energy of the clamping spring 12 can continuously push the sealing pressure plate 6 down to further improve the sealing effect and reduce the probability of leakage.

[0027] Example 2

[0028] See Figure 3 Furthermore, based on Embodiment 1, a sealing plate 8 is movably installed on the outer ring of the fixing rod 7 on the side away from the pot lid 4. The end of the fixing rod 7 is threaded with a bolt head 9, which is used to remove the sealing plate 8 by unscrewing the bolt head 9. The outer ring of the sealing plate 8 is provided with an annular groove, and a sealing ring 10 is sleeved in the annular groove. Several spherical slots are provided on the outer ring of the sealing pressure plate 6 on the side away from the pot lid 4. The top surface of the sealing gasket 11 is provided with a silicone ball that is compatible with the spherical slots. The sealing gasket 11 is installed on the side of the sealing pressure plate 6 away from the pot lid 4 by interference fit between the silicone ball and the spherical slots.

[0029] Specifically, because the sealing ring 10 is stuck in the annular groove of the sealing plug plate 8, and the sealing gasket 11 is stuck on the bottom surface of the sealing pressure plate 6 by the interference fit of the silicone ball, when it is necessary to disassemble and clean, the sealing ring 10 and the sealing gasket 11 can be directly removed for cleaning. When it is necessary to clean the whole thing, the personnel can unscrew the bolt head 9 and the fixing nut set at the anti-detachment ring plate 5, and then the sealing plug plate 8 and the sealing pressure plate 6 can be removed for cleaning. Each part is not connected to the pot lid 4 as a whole, so that the personnel can disassemble and rinse them separately, prevent water from entering the pot lid 4 and short-circuit, and eliminate cleaning dead corners.

[0030] In actual operation, since the sealing pressure plate 6 and the sealing plug plate 8 are installed on the bottom surface of the pot lid 4 through multiple components, and the size of the sealing plug plate 8 is adapted to match the inner diameter of the inner pot 2, when the pot lid 4 is placed on the rice cooker body 1 during the cooking process, the sealing plug plate 8 will be inserted into the inner pot 2, and the sealing pressure plate 6 will be placed on the top surface of the inner pot 2. At this time, multiple concave and convex sealing structures can be formed to improve the sealing effect. Meanwhile, the sealing pressure plate 6 is movably installed on the pot lid 4, and the bottom surface of the sealing pressure plate 6 is provided with a sealing gasket 11, and the sealing ring 10 is fitted on the outer ring of the sealing plug plate 8, which can effectively reduce the gap at the joint. At the same time, the top of the sealing pressure plate 6 abuts against the clamping spring 12. The elastic potential energy of the clamping spring 12 can continuously push the sealing pressure plate 6 down to further improve the sealing effect and reduce the probability of leakage.

[0031] Because the sealing ring 10 is stuck in the annular groove of the sealing plug plate 8, and the sealing gasket 11 is stuck on the bottom surface of the sealing pressure plate 6 by the silicone ball interference fit, when it is necessary to disassemble and clean, the sealing ring 10 and the sealing gasket 11 can be directly removed for cleaning. When it is necessary to clean the whole, the personnel can unscrew the bolt head 9 and the fixing nut set at the anti-detachment ring plate 5, and then the sealing plug plate 8 and the sealing pressure plate 6 can be removed for cleaning. Each part is not connected to the pot lid 4 as a whole, so that the personnel can disassemble and rinse separately, prevent water from entering the pot lid 4 and short circuit, and eliminate cleaning dead corners.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
