Description

Technical Field

[0001] The utility model relates to the field of household appliances, and in particular to a pot cover component and a rice cooking utensil. Background Art

[0002] An electric rice cooker is a kitchen appliance that can achieve a variety of cooking methods such as steaming, boiling, stewing, simmering, and braising. In existing electric rice cookers, the lid is mainly opened or closed on the pot body in a rotating manner. A sealing ring is provided on the inner side of the lid. When the lid is closed, the sealing ring is pressed and sealed between the lid and the inner pot of the pot body. Since the lid is mostly made of plastic, long-term high-temperature cooking will cause the lid to deform. Once the lid is deformed, it is difficult for the sealing ring and the inner pot to fit tightly. There is a gap between the two, which causes steam to easily dissipate from the edge of the inner pot during cooking, thereby affecting the quality of the cooked rice.

[0003] In addition, some people have proposed to set the pot cover as an outer cover and an inner cover that is movable relative to the outer cover, the sealing ring is set on the inner cover, and the middle part of the inner cover is connected to the outer cover through an elastic silicone member; this structure hopes that when the cover is closed, the inner cover and the sealing ring can be pressed against the inner pot of the pot based on the elastic force of the elastic silicone member. However, since the thickness of the inner cover is relatively thin and the elastic silicone member is connected to the middle part of the inner cover, and the sealing ring is located at the edge of the inner cover; when the cover is sealed, the reverse restoring force of the elastic silicone member can only act on the middle part of the inner cover to deform the inner cover. This elastic force is difficult to reach the edge of the inner cover to press the sealing ring located on the edge of the inner cover, so the sealing performance is limited and it is difficult to be applied to rice cooking utensils that require high sealing performance in the pot, such as drain rice electric rice cookers. Similarly, once the inner cover or the outer cover is deformed, part of the upper area of ​​the sealing ring will be difficult to press against the upper edge of the inner pot, resulting in steam leakage.

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a rice cooker cover assembly and a rice cooking utensil which have good sealing performance and can compensate for the deformation of the cover body.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a pot cover assembly, which includes a cover body, a condensation plate assembly and at least one elastic clamping assembly. The condensation plate assembly includes a condensation plate and a condensation plate sealing ring arranged at the edge of the condensation plate, and the condensation plate is detachably connected to the cover body and the condensation plate is movable relative to the cover body. At least one elastic clamping assembly is arranged between the cover body and the condensation plate, and each elastic clamping assembly includes a compression spring connected to the cover body and a push rod fixed on the compression spring, and the compression spring is elastically deformed along the closing direction of the cover body, and the front end of the push rod abuts against the edge of the condensation plate and is opposite to the condensation plate sealing ring; when the cover body is closed, it is blocked by the pot body assembly, and the condensation plate assembly moves in the direction of the cover body and causes the compression spring to undergo elastic deformation, and the compression spring generates a reverse restoring force perpendicular to the edge of the condensation plate to press the condensation plate and the condensation plate sealing ring to the pot body assembly.

[0006] According to an embodiment of the utility model, the pot cover assembly includes a plurality of elastic pressing assemblies, and the plurality of elastic pressing assemblies are distributed at intervals along the edge of the condensation plate.

[0007] According to one embodiment of the utility model, based on the deformation of the cover body, when it is covered on the pot body assembly, multiple elastic clamping assemblies have different deformation amounts to compensate for the deformation of the cover body or the condensation plate, and the multiple elastic clamping assemblies synchronously compress the condensation plate sealing ring in the circumferential direction.

[0008] According to one embodiment of the utility model, the middle part of the condensation plate is detachably connected to the cover body through an elastic silicone member with a single-end open end, a condensation plate assembly hole is opened in the middle part of the condensation plate, the upper end of the elastic silicone member passes through the condensation plate assembly hole and is interference fit on the condensation plate fixing portion on the cover body, and a travel cavity matching the movement of the condensation plate is formed in the inner cavity of the elastic silicone member, and the edge of the condensation plate assembly hole is engaged with the groove on the outer wall of the elastic silicone member.

[0009] According to one embodiment of the utility model, the condensation plate assembly also includes a condensation plate bracket, the edge of the condensation plate bracket is formed with an annular groove for buckling the condensation plate and the condensation plate sealing ring, and the front end of the push rod abuts the condensation plate at the annular groove.

[0010] According to one embodiment of the utility model, an assembly cavity with an opening toward the inner side of the cover body is formed on the cover body, and a limiting portion with an inwardly bent and flanged edge is formed at the open end of the assembly cavity; a compression spring is arranged in the assembly cavity, and a push rod is sleeved in the compression spring and a limiting matching portion is formed at the bottom end of the push rod to cooperate with the limiting portion to limit the push rod in the assembly cavity.

[0013] According to an embodiment of the utility model, the pot cover assembly further comprises at least one electrode assembly whose upper end is connected to the cover body and whose lower end passes through the condensation plate and extends into the pot body assembly.

[0014] On the other hand, the utility model also provides a rice cooking utensil, which comprises the above-mentioned pot cover assembly, and the rice cooking utensil is an IH rice cooker or a drain rice cooker.

On this basis, at least one elastic pressing assembly is arranged between the edge of the condensation plate and the cover body, and the elastic pressing assembly is opposite to the condensation plate sealing ring located at the edge of the condensation plate. This arrangement enables the condensation plate to move in the direction of the cover body due to the obstruction of the pot body assembly when the cover body is closed on the pot body assembly, and squeezes the elastic pressing assembly located at the edge of the condensation plate to cause elastic deformation, and the restoring force generated by the deformation of the elastic pressing assembly directly acts on the condensation plate sealing ring arranged opposite to it through the edge of the condensation plate, vertically pressing the condensation plate sealing ring to the pot body assembly to achieve the sealed closing of the pot cover assembly and the pot body assembly. When the condensation plate or the cover body is deformed, multiple elastic pressing groups can have different compression amounts to compensate for the deformation, ensuring that the condensation plate sealing ring can always be pressed into the pot body assembly when the pot cover assembly is closed.

[0023] like Figure 1 As shown, this embodiment provides a rice cooking utensil, which includes a pot cover assembly 100 and a pot body assembly 200. The pot body assembly 200 includes an inner pot 201, an outer shell 202 covering the inner pot 201, and a heating assembly 203 arranged in the bottom wall of the outer shell 202.

[0024] For the pot cover assembly 100, as shown in 1 to Figure 3As shown, it includes a cover body 1, a condensation plate assembly 2 and at least one elastic pressing assembly 3. The condensation plate assembly 2 includes a condensation plate 21 and a condensation plate sealing ring 22 arranged at the edge of the condensation plate 21. The condensation plate 21 is detachably connected to the cover body 1 and the condensation plate 21 is movable relative to the cover body 1. At least one elastic pressing assembly 3 is arranged between the cover body 1 and the condensation plate 21. Each elastic pressing assembly 3 includes a compression spring 31 connected to the cover body 1 and a push rod 32 sleeved and fixed on the compression spring 31. The compression spring 31 is elastically deformed along the closing direction of the cover body 1. The front end of the push rod 32 abuts against the edge of the condensation plate 21 and is opposite to the condensation plate sealing ring 22. When the cover body 21 is closed, it is blocked by the pot body assembly 200, and the condensation plate assembly 2 moves in the direction of the cover body 1 and causes the compression spring 31 to be elastically deformed. The compression spring 31 generates a reverse restoring force perpendicular to the edge of the condensation plate 21 to press the condensation plate 21 and the condensation plate sealing ring 22 against the pot body assembly 200.

[0025] In this embodiment, if Figure 4 As shown, the pot cover assembly 100 includes a plurality of elastic clamping assemblies 3, and the plurality of elastic clamping assemblies 3 are evenly spaced along the edge of the condensation plate 21. When the pot cover assembly 100 is closed, the plurality of elastic clamping assemblies 3 synchronously compress the condensation plate sealing ring 22 in the circumferential direction through the edge of the condensation plate. However, the utility model does not impose any limitation on the number of elastic clamping assemblies. In other embodiments, when the middle part of the condensation plate is connected to the cover body through an elastic silicone member, only one elastic clamping assembly may be provided and the elastic clamping assembly may be provided at the farthest distance from the hinge axis of the cover body; alternatively, the elastic clamping assembly may be provided at a portion of the cover body or the condensation plate that is easily deformed.

[0026] In the pot cover assembly provided in this embodiment, the front end of the push rod 32 in the elastic clamping assembly 3 abuts against the edge of the condensing plate 21 where the condensing plate sealing ring 21 is located. When the cover body 1 covers and squeezes the compression spring 31, the reverse force generated by the compression spring 31 will directly act on the condensing plate sealing ring 22 through the push rod 32, pressing the condensing plate sealing ring 22 against the pot body assembly 200 to achieve a sealed connection. Further, when the cover body 1 or the condensing plate 21 is deformed, the elastic clamping assembly 3 located near the deformation will have a deformation amount different from that of other elastic clamping assemblies 3, thereby compensating for the deformation of the cover body 1 or the condensing plate 21 so that the condensing plate sealing ring 22 can always be pressed against the pot body assembly 200 in the entire circumferential direction. In this embodiment, the condensing plate 21 is made of a food-safe metal material, such as 304 or 316 stainless steel, which is not easy to deform while achieving cooking steam condensation.

[0027] In this embodiment, if Figure 5As shown, the cover body 1 is provided with an assembly cavity 10 with an opening toward the inner side of the cover body, and a limit portion 101 with an inwardly bent flange is formed at the open end of the assembly cavity 10; a compression spring 31 is arranged in the assembly cavity 10, and a push rod 32 is sleeved in the compression spring 31, and a limit matching portion 321 is formed at the bottom end of the push rod 32 to cooperate with the limit portion 101 to limit the push rod 32 in the assembly cavity 10. Specifically, the cover body 1 includes a surface cover 11 and a lining cover 12 arranged on the inner side of the surface cover 11, an assembly hole is provided on the lining cover 12, and a blocking plate 13 is arranged on one end of the assembly hole close to the surface cover 11, the blocking plate 13 and the assembly hole are surrounded to form the assembly cavity 10, and the compression spring 31 is fixedly connected to the blocking plate 13. Further, the pot cover assembly 100 also includes a sealing ring 14 arranged between the blocking plate 13 and the assembly hole. An assembly hole is provided in the lining cover 12 and the assembly hole is sealed by a sealing plate 13 to form an assembly cavity. This arrangement not only greatly simplifies the forming of the assembly cavity 10, but also greatly facilitates the assembly and replacement of the compression spring 31. The arrangement of the sealing ring 14 effectively prevents steam from leaking from the assembly hole, ensuring that the rice cooking utensil has good sealing after the pot cover assembly 100 is closed. However, the utility model does not make any limitation to this. In other embodiments, a blind hole may also be provided in the cover body, and an assembly cavity for assembling the compression spring is formed based on the inner cavity of the blind hole. In addition, the cover body may also be provided as an integral structure.

[0028] In this embodiment, the middle part of the condensation plate 21 is detachably connected to the cover body 1 through an elastic silicone member 23 with a single open end. Figure 6 As shown, a condensation plate assembly hole 211 is opened in the middle of the condensation plate 21, the upper end of the elastic silicone member 23 passes through the condensation plate assembly hole 211 and is interference fit on the condensation plate fixing portion 15 on the cover body 1, and the inner cavity of the elastic silicone member 23 forms a travel cavity 231 matching the movement of the condensation plate 21, and the edge of the condensation plate assembly hole 211 is engaged with the slot 232 on the outer wall of the elastic silicone member 23.

[0029] like Figure 1 and Figure 2As shown, when the pot cover assembly 100 is covered on the pot body assembly 200, the condensing plate sealing ring 22 abuts against the upper edge of the inner pot 201 in the pot body assembly 200. Since the position of the inner pot 201 is fixed, when the pot cover assembly 100 is covered downward, the condensing plate assembly 2 is lifted up by the inner pot 201 and moves in the direction where the cover body 1 is located. At this time, the elastic silicone member 23 also moves in the direction where the cover body 1 is located following the condensing plate 21, and the travel cavity 231 provides a travel space for the movement of the elastic silicone member 23 and the condensing plate 21. While the condensation plate 21 is moving, the open end side walls of the multiple elastic clamping components 3 and the elastic silicone member 23 are squeezed, and the multiple elastic clamping components 3 generate a reverse restoring force directed to the condensation plate sealing ring 22 to press the condensation plate sealing ring 22 against the upper edge of the inner tank 201; at the same time, the open end side walls of the elastic silicone member 23 also generate a reverse force directed to the middle of the condensation plate 21, and this force is superimposed on the reverse restoring force of the multiple elastic clamping components 3 to further press the condensation plate 21 and the condensation plate sealing ring 22. However, the utility model does not make any limitation to this. In other embodiments, the middle part of the condensation plate may not need to be connected through the elastic silicone member, and it only needs to be detachably and movably connected to the cover body.

[0030] like Figure 2 and Figure 3 As shown, the condenser panel assembly 2 further includes a condenser panel bracket 24, the edge of which is formed with an annular groove 241 for buckling the condenser panel 21 and the condenser panel sealing ring 22, and the front end of the push rod 32 abuts against the condenser panel 21 at the annular groove 241. The condenser panel bracket 24 supports the condenser panel 21 to improve the connection strength after it is assembled on the cover body 1.

[0031] In this embodiment, the pot cover assembly 100 further includes at least one electrode assembly 4 whose upper end is connected to the cover body 1 and whose lower end passes through the condensation plate 21 and extends into the inner pot 201 for detecting the water level of the inner pot.

[0032] Although this embodiment Figure 1 The IH rice cooker shown is used as an example of a rice cooking utensil for explanation. However, the present invention does not make any limitation to this. The pot cover assembly provided by the present invention is also applicable to a drain rice cooker; for a drain rice cooker, since the pot body assembly includes a shell, an upper pot, a lower pot and a heating assembly, the condensing plate sealing ring will also be pressed against the upper edge of the upper pot when the pot cover assembly is closed.

[0033] In summary, in the pot cover assembly provided by the utility model, the condensation plate is detachably connected to the cover body and is movable relative to the cover body. On this basis, at least one elastic pressing assembly is arranged between the edge of the condensation plate and the cover body, and the elastic pressing assembly is opposite to the condensation plate sealing ring located at the edge of the condensation plate. This arrangement enables the condensation plate to move in the direction of the cover body due to the obstruction of the pot body assembly when the cover body is closed on the pot body assembly, and squeezes the elastic pressing assembly located at the edge of the condensation plate to cause elastic deformation, and the restoring force generated by the deformation of the elastic pressing assembly directly acts on the condensation plate sealing ring arranged opposite to it through the edge of the condensation plate, vertically pressing the condensation plate sealing ring to the pot body assembly to achieve the sealed closing of the pot cover assembly and the pot body assembly. When the condensation plate or the cover body is deformed, multiple elastic pressing groups can have different compression amounts to compensate for the deformation, ensuring that the condensation plate sealing ring can always be pressed into the pot body assembly when the pot cover assembly is closed.

[0034] Although the present invention has been disclosed as above by the preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope required by the claims.
