TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooking utensils, in particular to a cover body and a cooking utensil. BACKGROUND

[0002] At present, the electric cooker is provided with a torsion spring to realize automatic cover opening, however, due to the large elastic force of the torsion spring, the tip of the torsion spring arm is prone to movement when it is deformed, which is prone to interference with the cable arranged in the cover body, and there is a safety risk of cable damage.

[0003] Therefore, a cover body and a cooking utensil are needed to at least partially solve the above problems. SUMMARY

[0004] A series of simplified concepts are introduced in the summary part, which will be further described in detail in the specific embodiment part. The summary part of the utility model does not mean to try to limit the key features and necessary technical features of the claimed technical solution, and even less means to determine the protection scope of the claimed technical solution.

[0005] To at least partially solve the above problems, the first aspect of the utility model provides a cover body for a cooking utensil, which comprises:

[0006] An inner liner is provided with a cable, and the inner liner is further provided with a shielding part, the shielding part has an accommodation space, and the cable is located outside the shielding part;

[0007] A pivot shaft is arranged on the inner liner, and the pivot shaft is further used to connect with a pot body of the cooking utensil, so that the cover body can rotate around the pivot shaft as an axis;

[0008] A torsion spring is arranged on the pivot shaft, and the torsion spring has a first arm and a second arm, wherein the first arm is connected to the inner liner, the second arm is used to connect with the pot body, and the end of the first arm is located in the accommodation space.

[0009] According to the cover body of the application, the cable is isolated from the torsion spring by the shielding part on the inner liner, which is conducive to reducing the possibility of safety risk caused by the end of the torsion spring arm piercing the cable.

[0010] Optionally, the accommodation space of the shielding part has a first opening towards the pivot shaft, and the end of the first arm extends into the accommodation space through the first opening. According to the above arrangement, the assembly of the torsion spring is facilitated.

[0011] Optionally, the liner includes a main body, and the shielding portion includes a baffle rib protruding from the main body. The baffle rib encloses the receiving space and forms the first opening towards the pivot axis. According to the above configuration, by providing the baffle rib, not only can the cable and the torsion spring be isolated, but the liner's resistance to warping deformation can also be improved, which is beneficial for better bearing the elastic force when the torsion spring deforms.

[0012] Optionally, the retaining rib includes:

[0013] Side ribs, the side ribs extending along a first direction, and two side ribs being spaced apart;

[0014] A front rib extends along a second direction and connects to one end of the two side ribs. The other ends of the two side ribs form the first opening. The first direction is orthogonal to the second direction. According to this arrangement, isolation from the cable can be formed on both sides and the front side of the end of the first arm of the torsion spring, improving safety.

[0045] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0046] refer to Figure 1 This application provides a cooking appliance 10, which includes a lid 100 and a pot body 20. The lid 100 has a shape that substantially corresponds to the pot body 20. The lid 100 is closable on the pot body 20. The lid 100 can be pivotally connected to the pot body 20, for example, via a pivot axis 130, and can pivot freely about the axis of the pivot axis 130 between a closed position and an open position relative to the pot body 20, to facilitate closing and opening the pot body 20.

[0047] The pot body 20 includes an inner pot and has a cylindrical storage compartment. The inner pot can be freely placed into or removed from the storage compartment for easy cleaning. The inner pot is typically made of metal and has a circular opening on its upper surface for holding materials to be heated, such as rice or soup.

[0048] The pot body 20 includes a heating device for heating the inner pot. This heating device is located below the inner pot. The heating device can be a device such as a heating plate.

[0049] When the lid 100 is closed on the pot body 20, it covers the inner pot and forms a cooking space between them. The lid 100 usually also has a pot opening sealing ring, which can be made of, for example, rubber material, and is positioned between the lid 100 and the inner pot to seal the cooking space when the lid 100 is closed.

[0050] It is understood that the cooking appliance 10 according to this application can be a rice cooker, an electric pressure cooker or other cooking appliance 10, and the cooking appliance 10 can have various functions such as cooking porridge in addition to cooking rice.

[0051] refer to Figure 2 The lid 100 may specifically include a top cover 110 and an inner liner 120, with the top cover 110 disposed on the upper side of the inner liner 120. In some alternative embodiments, the lid 100 may also include a removable cover disposed on the lower side of the inner liner 120. To enable the lid 100 to open automatically, the lid 100 preferably also includes a torsion spring 140. The torsion spring 140 is disposed on a pivot 130. Specifically, the torsion spring 140 includes a spring body 141 and a first arm 142 and a second arm 143 extending from the spring body 141, wherein the first arm 142 extends along a first direction D1 and connects to the inner liner 120 of the lid 100, and the second arm 143 connects to the pot body 20. For example, in the illustrated embodiment, two torsion springs 140 are provided. The first direction D1 can be understood as the front-rear direction of the lid 100.

[0052] In some embodiments, electronic devices are housed in the cover 100, and therefore cables 150 are also present in the cover 100. For example, an upper temperature sensing element 101 may be provided on the cover 100, and the cable 150 may be connected to the upper temperature sensing element 101. Specifically, the cable 150 is disposed in the liner 120, or in other words, is routed on the liner 120. The liner 120 is also provided with a shielding portion 121, which has a receiving space 125, and the cable 150 is located outside the shielding portion 121. The end of the first arm 142 of the torsion spring 140 is located in the receiving space 125.

[0053] According to the cover 100 of this application, the cable 150 is separated from the torsion spring 140 by the shielding part 121 on the liner 120, which helps to reduce the possibility of the end of the torsion spring arm puncturing the cable 150 and causing a safety risk.

[0054] refer to Figure 2 and Figure 3The liner 120 includes a main body 127, with a shielding portion 121 connected to the main body 127. The receiving space 125 of the shielding portion 121 has a first opening facing a pivot axis 130, and the end of a first arm 142 extends into the receiving space 125 via the first opening. As one implementation, the shielding portion 121 includes a baffle 122 protruding from the main body 127, the baffle 122 surrounding the receiving space 125 and forming the first opening facing the pivot axis 130. Preferably, the baffle 122 and the main body 127 are constructed as an integral part. Exemplarily, the baffle 122 can be formed in one step while molding the liner 120. By providing the baffle 122, not only can the cable 150 and the torsion spring 140 be isolated, but the anti-warping deformation capability of the liner 120 can also be improved, which is beneficial for better bearing the elastic force of the torsion spring 140 during deformation.

[0055] To facilitate mold design and reduce defects during injection molding, the baffle 122 can be configured as an open type. Specifically, the accommodating space 125 also has a second opening, which is positioned away from the main body 127.

[0056] More specifically, the retaining rib 122 includes side ribs 123 and front ribs 124. The side ribs 123 extend along a first direction D1, and the two side ribs 123 are spaced apart. The front rib 124 extends along a second direction D2 and connects to one end of the two side ribs 123, with the other end of the two side ribs 123 forming a first opening. The first direction D1 is orthogonal to the second direction D2. The second direction D2 can be understood as the left-right direction of the cover 100. This structural form can create isolation from the cable 150 on both sides and the front of the end of the first arm 142 of the torsion spring 140, improving safety.

[0057] In another embodiment, the second opening may be omitted; that is, the baffle 122 may be configured to be closed in all positions except for the first opening. This not only isolates the ends and front of the first arm 142 of the torsion spring 140 from the cable 150, but also isolates the torsion spring 140 from the cable 150 in the direction facing the inner liner 120, further improving safety. Specifically, refer to... Figure 4 The shielding portion 121 may also include a cover 226, which is connected to the end of the baffle 122 facing away from the main body 127. More specifically, the cover 226 may be connected to the ends of both the side baffle 123 and the front baffle 124.

[0058] Since an integrated design of the cover 226 and the retaining rib 122 would lead to complex mold manufacturing difficulties, the cover 226 and the retaining rib 122 are preferably designed as separate components. In other words, they can be detachably connected. Thus, the integral molding of the retaining rib 122 and the main body 127 facilitates mold processing, while the additional detachable cover 226 can, on the basis of mold processing, also isolate the torsion spring 140 from the cable 150 in the direction facing the inner liner 120.

[0059] In an embodiment not shown, the shielding portion 121 can also be designed to form a closed structure except for the first opening, without the baffle 122. For example, the shielding portion 121 can have an arcuate surface protruding away from the inner liner 120. In other words, the shielding portion 121 can be constructed as a spherical cover, which is connected to the body 127 by fastening it onto the body 127. In this way, while having a high level of safety, the spherical structure can further improve the anti-warping ability of the inner liner 120.

The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention. Features described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.
