Description

Technical Field

[0001] This utility model relates to the field of rice cookers, specifically a limiting structure for a rice cooker. Background Technology

[0002] Existing rice cooker structures, as shown in Chinese patent document (application number: 201621131123.X) for a plug-in type rice cooker, mainly disclose a cooker body, a lid, an intelligent circuit, and a heating element. The cooker body has a cavity containing an inner pot and a steamer that can be placed inside the inner pot. The lid is connected to the top of the cooker body via a hinge structure. However, when the hinge structure lacks an opening limit structure, the lid can only be allowed to flip backward during the opening process. It is only when the lid hits the rear wall that the opening is limited, which easily causes damage or scratches to the lid. Moreover, when the rice cooker is a commercial rice cooker, the volume of the commercial rice cooker is large, and the corresponding weight of the lid is also large. Therefore, allowing the lid to open freely without a limit increases the pressure on the hinge structure, which is prone to damage. Therefore, the applicant has improved and perfected the existing structure to solve the above problems and provide consumers with a choice for use. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned existing problems and provide a simple and reasonable limiting structure for a rice cooker.

[0004] A limiting structure for a rice cooker includes a rice cooker body and a lid. The lid is hinged to the rice cooker body. An upper limiting corner block is connected to the rear side of the lid, and the upper limiting corner block has a downward-facing upper limiting slope. A lower limiting corner block is connected to the rear side of the rice cooker body near the upper limiting corner block, and the lower limiting corner block has an upward-facing lower limiting slope. When the lid is opened, the upper limiting slope abuts against the lower limiting slope, thereby limiting the opening of the lid.

[0005] The objective of this utility model can also be achieved by the following technical measures: As a more specific embodiment, the maximum included angle between the upper limit inclined plane and the lower limit inclined plane is greater than or equal to 90°.

[0006] As a further embodiment, the upper limit slope and the lower limit slope have the same tilt angle relative to the horizontal plane.

[0007] As a further option, the upper limit corner block and the lower limit corner block have the same structure.

[0008] As a further option, the upper limit corner block and the lower limit corner block are made by bending sheet metal parts.

[0009] As a further embodiment, both the rice cooker body and the lid include an outer shell, and a support plate is provided on the inner side of the outer shell. Both the upper limit corner block and the lower limit corner block extend with connecting plates. The connecting plates are fastened to the support plate and clamp the outer shell between the connecting plate and the support plate.

[0010] As a further embodiment, the hinge structure includes a pivot shaft and a lower hinge and an upper hinge that are rotatably hinged to the pivot shaft. The lower hinge is fastened to a support plate in the rice cooker body, and the upper hinge is fastened to a support plate in the lid.

[0011] As a further solution, the upper limit corner block is provided with an upper limit inclined surface that is spaced from the bottom end face of the lid, and the lower limit corner block is provided with a lower limit inclined surface that is spaced from the top end face of the rice cooker body. When the lid is opened, the bottom end face, the top end face, the lid, and the rice cooker body together enclose and define a hinge clearance cavity.

[0012] As a further solution, the connecting plate is provided with a number of external connection holes, and the outer shell and the support plate are respectively provided with through holes and internal connection holes corresponding to the external connection holes. The fastening unit passes through the external connection holes, through holes and internal connection holes in sequence to realize that the upper limit corner block is fastened to the pot lid and the lower limit corner block is fastened to the rice cooker body.

[0013] As a further embodiment, the rice cooker body also includes an outer shell and an inner pot placed inside the outer shell. A heating element is connected to the bottom surface of the inner pot, and a steamer can be placed inside the inner pot. The steamer has a through hole that connects to the inner cavity of the inner pot, and a gap is left between the bottom of the steamer and the bottom of the inner pot.

[0014] The beneficial effects of this utility model are as follows: This utility model discloses a limiting structure for a rice cooker. This limiting structure can control the maximum opening angle of the lid and prevent the lid from swinging back and hitting the wall. Moreover, the upper and lower limiting slopes basically cover the entire width of the rice cooker, so that the force generated by the lid when opening can be evenly distributed along the width direction, reducing the pressure on the hinge structure. Even if a heavy lid is used, the upper and lower limiting corner blocks can resist the impact between each other, maintain the integrity of the structure, and will not deform or break due to force.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1 to 4 As shown, a limiting structure for a rice cooker includes a rice cooker body 1 and a lid 2. The lid 2 is connected to the rice cooker body 1 via a hinge structure 3. An upper limit corner block 4 is connected to the rear side of the lid 2. The upper limit corner block 4 has a downward-facing upper limit slope 401. A lower limit corner block 5 is connected to the rear side of the rice cooker body 1 near the upper limit corner block 4. The lower limit corner block 5 has an upward-facing lower limit slope 501. When the lid 2 is opened, the upper limit slope 401 abuts against the lower limit slope 501, thereby limiting the opening of the lid.

[0024] This rice cooker uses a limiting structure that can control the maximum opening angle of the lid and prevent the lid 2 from swinging back and hitting the wall. Moreover, the upper limit slope 401 and the lower limit slope 501 basically cover the entire width of the rice cooker, so that the force generated by the lid 2 when opening can be evenly distributed along the width direction, reducing the pressure on the hinge structure 3. Even if a heavy lid 2 is used, the upper limit corner block 4 and the lower limit corner block 5 can resist the impact between each other, maintain the integrity of the structure, and will not deform or break due to force.

[0025] The maximum included angle α between the upper limit inclined surface 401 and the lower limit inclined surface 501 is greater than or equal to 90°. The included angle between the two determines the opening angle of the lid 2. In this embodiment, the maximum included angle α is preferably greater than 90° but less than 120°. This angle range allows the center of gravity of the lid 2 to lean back after the lid is opened, preventing the lid 2 from automatically closing and causing pinching accidents. At the same time, it can also prevent the lid 2 from leaning too far back and colliding with the wall.

[0026] The upper limit inclined surface 401 and the lower limit inclined surface 501 have the same tilt angle relative to the horizontal plane. Of course, in other embodiments, the tilt angles of the upper limit inclined surface 401 and the lower limit inclined surface 501 relative to the horizontal plane can also be one larger and one smaller. In this case, the maximum included angle α can still be greater than or equal to 90°. The upper limit corner block 4 and the lower limit corner block 5 have the same structure, so that the upper limit corner block 4 and the lower limit corner block 5 do not need to be produced separately. Only parts of the same specification need to be produced, which can reduce production costs. During assembly, workers only need to identify the up and down direction of the inclined plane, which improves the assembly efficiency of the rice cooker.

[0027] In this embodiment, the upper limit corner block 4 and the lower limit corner block 5 are made by bending sheet metal parts; bending sheet metal parts can improve sufficient strength, prevent deformation, and reduce the weight of the upper limit corner block 4 and the lower limit corner block 5.

[0028] See Figure 5 and Figure 6 As shown, both the rice cooker body 1 and the lid 2 include an outer shell 6. The inner side of the outer shell 6 is provided with a support plate 7. The upper limit corner block 4 and the lower limit corner block 5 both extend with a connecting plate 8. The connecting plate 8 is fastened to the support plate 7 and clamps the outer shell 6 between the connecting plate 8 and the support plate 7. When the upper limit corner block 4 and the lower limit corner block 5 are directly connected to the outer shell 6, the force will only be applied to the connection point between the upper limit corner block 4 and the lid 2, and the connection point between the lower limit corner block 5 and the rice cooker body 1 when the lid is opened, causing the outer shell 6 to deform or shrink. However, by connecting the upper limit corner block 4 and the lower limit corner block 5 to the support plate 7, the force can be distributed across the contact area between the support plate 7 and the outer shell 6, maintaining the overall shape of the outer shell.

[0029] Meanwhile, the hinge structure 3 includes a pivot shaft 31 and a lower hinge 32 and an upper hinge 33 rotatably hinged to the pivot shaft 31. The lower hinge 32 is fastened to the support plate 7 in the rice cooker body 1, and the upper hinge 33 is fastened to the support plate 7 in the lid 2. This transfers the force between the upper limit corner block 4 and the lower limit corner block 5 when the lid is opened to the hinge structure 3, so that the outer shell does not provide support.

[0030] The upper limit corner block 4 is provided with an upper limit inclined surface 401 and a bottom end surface 402 of the lid 2, and the lower limit corner block 5 is provided with a lower limit inclined surface 501 and a top end surface 502 of the rice cooker body 1. When the lid 2 is opened, the bottom end surface 402, the top end surface 502, the lid 2 and the rice cooker body 1 together define a hinge clearance cavity X. The pivot shaft 31 in the above-mentioned hinge structure 3 is exposed on the outer shell and is located between the upper limit corner block 4 and the lower limit corner block 5. Therefore, when the lid is opened, a hinge clearance cavity X needs to be formed so that the pivot shaft 31 will not be sandwiched between the limit corner block 4 and the lower limit corner block 5.

[0031] The connecting plate 8 has several external connecting holes 801. The outer shell 6 and the support plate 7 have through holes 601 and internal connecting holes 701 respectively corresponding to the external connecting holes 801. The fastening unit passes through the external connecting holes 801, through holes 601 and internal connecting holes 701 in sequence to fasten the upper limit corner block 4 to the lid 2 and the lower limit corner block 5 to the rice cooker body 1. The upper limit corner block 4 and the lower limit corner block 5 are installed by screw fastening, which is convenient for disassembly and position adjustment.

[0032] See Figure 7 As shown, the rice cooker body 1 also includes an outer shell 6 and an inner pot 10 placed inside the outer shell 6. The outer bottom surface of the inner pot 10 is connected to a heating element 11. A steamer 12 can be placed inside the inner pot 10. The steamer 12 is provided with a through hole 121 that communicates with the inner cavity of the inner pot 10, and a gap H is left between the bottom of the steamer 12 and the bottom of the inner pot 10. This structure can facilitate the cooking of rice in a steamer. Through intelligent control, the cooking of rice in a steamer can be achieved, and rice water can also be produced.

[0033] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
