Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, specifically to a lid-type cooking utensil. Background Technology

[0002] Currently, cooking appliances such as rice cookers and pressure cookers are usually designed with a hinge to open and close the lid relative to the pot body. At the same time, torsion springs are designed on the hinge shaft at both ends to abut between the lid and the pot body to make the lid automatically spring open when it is opened.

[0003] Because the torsion spring design needs to avoid the structural components at the hinge connection between the lid and the pot body, the movable arm of the torsion spring needs to be designed to protrude outwards in a bent shape. When the lid is opened relative to the pot body, the endpoint of the outwardly protruding bent torsion spring movable arm's return swing will extend beyond the pot body. Therefore, a clearance groove needs to be designed into the pot body of the rice cooker to correspond to the position of the torsion spring's movable arm, providing sufficient swing space for the torsion spring's movable arm when the lid is opened. However, the existence of the clearance groove not only affects the aesthetics of the rice cooker, but also makes it easy for foreign objects to enter the cooking appliance through the clearance groove, affecting the user experience. Utility Model Content

[0004] In view of this, the present invention provides a lid-opening cooking appliance to solve the problem that the clearance grooves in the current cooking appliance body design not only affect the aesthetics, but also easily allow foreign objects to enter the cooking appliance, affecting the user experience.

[0025] In one alternative embodiment, the first clearance groove is configured as an arc-shaped groove, the arc of which follows the rotation path of the transverse arm.

[0026] Beneficial effect: The first clearance groove is constructed as an arc groove to avoid the rotation of the transverse arm in the movable arm, ensuring the smooth rotation of the movable arm.

[0027] In one optional embodiment, the pot body includes a base and a support ring disposed on the base and provided with the mounting, and the lid includes a top cover and an inner cover disposed on the top cover.

[0062] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0063] A rice cooker provided in related technologies, such as Figure 1As shown, the pot body 1 is provided with a support ring 102, and the opening and closing lid hinge shaft 3 is located between the support ring 102 and the inner cover 202 of the lid body 2. The torsion spring 4 is installed in the mounting cavity 1022 of the support ring 102, so that the fixed arm 401 of the torsion spring 4 abuts against the support ring 102, and the movable arm 402 of the torsion spring 4 abuts against the inner cover 202. With this configuration, the movable arm 402 of the torsion spring 4 needs to extend beyond the top of the mounting cavity 1022 towards the lid body 2. That is to say, the movable arm 402 of the torsion spring 4 needs to be designed as an outwardly protruding bent shape. This means that the movable arm 402 of the torsion spring 4 first extends upward a certain length to pass the top of the mounting cavity 1022, and then extends towards the lid body 2 to abut against the inner cover 202 of the lid body 2. This results in the fulcrum position where the movable arm 402 of the torsion spring 4 abuts against the lid body 2 being too high. Thus, when the lid 2 opens relative to the pot body 1, the endpoint of the swing of the movable arm 402 of the torsion spring 4 will extend beyond the pot body 1. The specific movement path of the movable arm 402 of the torsion spring 4 is as follows: Figure 2 As shown. Therefore, it is necessary to design a clearance groove 7 on the pot body 1 of the rice cooker, corresponding to the position of the movable arm 402 of the torsion spring 4, that is, as shown. Figure 3 As shown, this provides sufficient swing space for the movable arm 402 of the torsion spring 4 when the lid is opened. However, the presence of the clearance groove 7 not only affects the aesthetics of the rice cooker, but also makes it easy for foreign objects to enter the rice cooker through the clearance groove 7, affecting the user experience.

[0064] Therefore, this embodiment provides a lid-type cooking appliance to solve the problem that the clearance grooves in the current cooking appliance body design not only affect the aesthetics, but also easily allow foreign objects to enter the cooking appliance, affecting the user experience.

[0065] The following is combined with Figures 4-13 The following describes embodiments of the present invention.

[0066] According to an embodiment of this utility model, a lid-opening cooking utensil is provided, such as... Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, it includes: pot body 1, lid 2, hinge shaft 3 and torsion spring 4.

[0067] The pot body 1 is provided with a mounting part 1021 having a mounting cavity 1022. The mounting part 1021 is provided with a first clearance part communicating with the mounting cavity 1022. The lid 2 is hinged to the mounting part 1021 via a hinge shaft 3 located in the mounting cavity 1022. The torsion spring 4 is located in the mounting cavity 1022. The main structure 403 of the torsion spring 4 is sleeved on the hinge shaft 3. The fixed arm 401 of the torsion spring 4 abuts against the pot body 1. The movable arm 402 of the torsion spring 4 extends out of the mounting cavity 1022 from the first clearance part and abuts against the lid 2.

[0068] In the above embodiment, a first clearance portion communicating with the mounting cavity 1022 is provided on the mounting part 1021 of the pot body 1, so that the movable arm 402 of the torsion spring 4 located in the mounting cavity 1022 can directly extend out of the mounting cavity 1022 through the first clearance portion and directly abut against the lid 2. The movable arm 402 does not need to first extend upward a certain length to pass over the top of the mounting cavity 1022 and then extend towards the lid 2 to abut against the lid 2. Therefore, it is not necessary to design the movable arm 402 of the torsion spring 4 as an outwardly protruding and bent structure. With this setting, the first clearance portion can reduce the bending height of the movable arm 402 when extending towards the lid 2. When the lid is opened, the endpoint of the movable arm 402's return swing will not exceed the edge of the pot body 1. Therefore, it is not necessary to design an avoidance groove in the pot body 1, thereby ensuring the aesthetics of the open-lid cooking appliance, preventing foreign objects from entering the rice cooker through the avoidance groove, and improving the user experience.

[0069] Specifically, such as Figure 6 , Figure 7 As shown, the pot body 1 is provided with a mounting part 1021 for hinged connection with the lid 2 via a hinge shaft 3. Since a torsion spring 4 also needs to be mounted on the hinge shaft 3, a mounting cavity 1022 is designed in the mounting part 1021 to accommodate the torsion spring 4. Due to the presence of the first clearance part, the movable arm 402 extending outward from the mounting cavity 1022 can directly extend out of the mounting cavity 1022 from the first clearance part. The movable arm 402 does not need to pass over the structural wall of the mounting part 1021 from the top of the mounting cavity 1022, and therefore does not need to be designed as an outwardly protruding and bent structure of the movable arm 402, thus reducing the bending height of the movable arm 402 when extending towards the lid 2. Figure 8 , Figure 9 , Figure 10 As shown, the movable arm 402 on the torsion spring 4 extends out of the mounting cavity 1022 through the first clearance part. Since the bending height of the movable arm 402 when it extends towards the lid 2 is reduced, the end point of the movable arm 402's return swing when the lid is opened will not exceed the edge of the pot body 1.

[0070] Furthermore, this embodiment does not limit the specific structural form of the first clearance portion. In one embodiment, the first clearance portion is configured as a recessed opening with a length or width equivalent to that of the wall where the mounting cavity 1022 is located, so that the movable arm 402 can extend out of the opening; in another embodiment, the first clearance portion is configured as a notch on the wall where the mounting cavity 1022 is located, so that the movable arm 402 can extend out of the notch.

[0071] Furthermore, in this embodiment, the location of the first clearance portion is not limited, and the mounting portion 1021 has a top wall, a rear wall, and a side wall. In one embodiment, notches are designed on the top and rear walls of the mounting portion 1021 to form the first clearance portion; in another embodiment, notches are designed on the side wall of the mounting portion 1021 to form the first clearance portion.

[0072] In some embodiments, as a preferred implementation, the height of the contact point between the movable arm 402 and the cover 2 is not higher than the height of the top of the main structure 403.

[0073] In the above embodiment, by limiting the height of the contact position between the movable arm 402 and the cover 2 to no higher than the height of the top of the main structure 403, the contact position between the movable arm 402 and the cover 2 is lower, so as to ensure that the endpoint of the movable arm 402's return swing when the cover is opened will not exceed the edge of the pot body 1.

[0074] Specifically, such as Figure 10 As shown, the height of the contact point between the movable arm 402 and the lid 2 is not higher than the height of the top of the main structure 403. Even if the movable arm 402 rotates 90° relative to the limit position before the lid is opened, the movable arm 402 as a whole will not exceed the edge of the pot body 1.

[0075] In some embodiments, such as Figure 6 , Figure 7 As shown, the cover 2 is provided with a mounting groove 2021, the mounting part 1021 is embedded in the mounting groove 2021, and the hinge shaft 3 is rotatably connected between the mounting part 1021 and the mounting groove 2021.

[0076] In the above embodiment, a mounting groove 2021 is provided on the lid 2 to fit into the mounting part 1021 of the pot body 1, so that the lid 2 and the pot body 1 can be assembled tightly and stably.

[0077] Specifically, four shaft holes are provided on the structural wall of the mounting part 1021 and the structural arm of the mounting groove 2021. When the lid 2 is assembled with the pot body 1, the hinge shaft 3 passes through the four shaft holes to hinge the lid 2 and the pot body 1 through the mounting part 1021 and the mounting groove 2021, and at the same time passes through the main structure 403 of the torsion spring 4 to fix its position.

[0078] In some embodiments, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the cover 2 is provided with a second clearance portion that communicates with the mounting portion, and the second clearance portion is positioned corresponding to the first clearance portion; the movable arm 402 of the torsion spring 4 extends out of the mounting cavity 1022 from the first clearance portion and extends out of the mounting groove 2021 from the second clearance portion, thereby abutting against the cover 2.

[0079] In the above embodiment, a second clearance portion is provided on the cover 2, which communicates with the mounting groove 2021, so that the movable arm 402 of the torsion spring 4, which extends out of the mounting cavity 1022 from the first clearance portion, can further extend out of the mounting groove 2021 from the second clearance portion to smoothly abut against the cover 2.

[0080] Specifically, the structural wall of the mounting groove 2021 is designed with a clearance mechanism for the extension of the fixing arm 401 of the torsion spring 4 to form a second clearance part. The setting position of the second clearance part corresponds to the first clearance part. In a preferred embodiment, the size of the slot or opening of the first clearance part and the second clearance part is equivalent.

[0081] Furthermore, this embodiment does not limit the specific structural form of the second clearance portion. In one embodiment, the second clearance portion is configured as a recessed opening with a width equivalent to that of the side wall where the mounting groove 2021 is located, so that the movable arm 402 can extend out of the opening; in another embodiment, the second clearance portion is configured as a notch on the side wall where the mounting groove 2021 is located, so that the movable arm 402 can extend out of the notch.

[0082] In some embodiments, such as Figure 6 , Figure 7 As shown, the first clearance part is set as the first clearance groove 1023, and the second clearance part is set as the second clearance groove 2022.

[0083] In the above embodiment, the first clearance portion is provided as a first clearance groove 1023 so that the movable arm 402 can move therein; the second clearance portion is provided as a second clearance groove 2022 so as to facilitate the assembly of the movable arm 402.

[0084] Specifically, the first clearance groove 1023 and the second clearance groove 2022 can be configured as a strip groove or an open groove.

[0085] In some embodiments, such as Figure 6 , Figure 7 As shown, the first clearance groove 1023 is located on the side of the mounting part 1021, and the second clearance groove 2022 is located on the side of the mounting groove 2021.

[0086] In the above embodiment, the first clearance groove 1023 and the second clearance groove 2022 are respectively provided on the side of the mounting cavity 1022 and the mounting groove 2021, so that the movable arm 402 of the torsion spring 4 extends from the side of the hinge position of the mounting part 1021 and the mounting groove 2021 and abuts against the cover 2 at a position off-center, leaving enough space near the center of the cover 2 for wiring and accessory installation.

[0087] Specifically, in this embodiment, a first clearance groove 1023 is provided on the side wall of the mounting part 1021 and a second clearance groove 2022 is provided at the corresponding position on the side of the mounting groove 2021. Compared with providing the first clearance groove 1023 on the top wall and the rear wall of the mounting part 1021 and providing the second clearance groove 2022 at the corresponding position on the side of the mounting groove 2021, the extension position of the movable arm 402 of the torsion spring 4 is further away from the middle position of the cover 2, thereby leaving enough space near the middle of the cover 2.

[0088] Furthermore, this embodiment does not limit the number of torsion springs 4. In one embodiment, one torsion spring 4 is provided, and it is located on one side of the hinge position between the mounting part 1021 and the mounting groove 2021; in another embodiment, two torsion springs 4 are provided, and they are located on both sides of the hinge position between the mounting part 1021 and the mounting groove 2021. This embodiment adopts the second arrangement method.

[0089] In some embodiments, such as Figure 7 , Figure 9 , Figure 11 , Figure 12 As shown, the movable arm 402 of the torsion spring 4 includes: a transverse arm 4021 and an abutment arm 4022.

[0090] The transverse arm 4021 is connected to the main body structure 403 of the torsion spring 4 and extends away from the end of the main body structure 403. The transverse arm 4021 is located in the first clearance groove 1023 and the second clearance groove 2022. The abutting arm 4022 is connected to the extended end of the transverse arm 4021 and extends towards the cover 2 and abuts against the cover 2.

[0091] In the above embodiment, a transverse arm 4021 is provided in the movable arm 402 to pass over the side wall of the mounting part 1021 and the side of the mounting groove 2021 through the first clearance groove 1023 and the second clearance groove 2022; an abutment arm 4022 is provided to extend in the direction of the cover 2 to smoothly abut against the cover 2.

[0092] Specifically, the main structure 403 of the torsion spring 4 is sleeved on the hinge shaft 3; the length of the transverse arm 4021 is slightly longer than the sum of the thicknesses of the first clearance groove 1023 and the second clearance groove 2022; without affecting the internal wiring and component layout of the cover 2, the abutting arm 4022 extends as far as possible towards the cover 2 to improve the stability of the abutting fit between the movable arm 402 of the torsion spring 4 and the cover 2.

[0093] In some embodiments, such as Figure 7 , Figure 9 As shown, the first clearance groove 1023 is constructed as an arc-shaped groove, and the arc of the arc-shaped groove is consistent with the rotation path of the transverse arm 4021.

[0094] In the above embodiment, the first clearance groove 1023 is constructed as an arc-shaped groove to avoid the rotation of the transverse arm 4021 in the movable arm 402, thereby ensuring the smooth rotation of the movable arm 402.

[0095] Specifically, the arc of the first clearance groove 1023 forming the arc groove is constructed with the shaft hole for mounting the hinge shaft 3 as the center.

[0096] Furthermore, in this embodiment, the second relief groove 2022 is constructed as an arc-shaped groove that conforms to the first relief groove 1023, so that the transverse arm 4021 can be smoothly installed along the arc-shaped structure of the first relief groove 1023 and the second relief groove 2022 when the torsion spring 4 is installed.

[0097] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the pot body 1 includes a base 101 and a support ring 102 disposed on the base 101 and mounted thereon. The lid 2 includes a top cover 201 and an inner cover 202 disposed on the top cover 201. The inner cover 202 is hinged to the mounting part 1021 via a hinge shaft 3. The fixed arm 401 of the torsion spring 4 abuts against the support ring 102, and the movable arm 402 of the torsion spring 4 abuts against the inner cover 202.

[0098] In the above embodiment, the pot body 1 and the lid 2 are rotatably connected by the hinge of the support ring 102 and the inner lid 202; the fixed arm 401 and the movable arm 402 of the torsion spring 4 are respectively abutted against the support ring 102 and the inner lid 202 for installation.

[0099] Specifically, the base 101 of the pot body 1 is used to set the inner pot cavity, etc., and the support ring 102 of the pot body 1 is used to set the electrical structure, wiring, etc.; the top cover 201 of the lid 2 is used to set the external decorative panel, etc., and the inner cover 202 of the lid 2 is used to set the electrical structure, insulation board, etc.

[0100] In some embodiments, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the support ring 102 is provided with a first limiting groove 1024, and the fixed arm 401 of the torsion spring 4 is provided in the first limiting groove 1024 to abut against the support ring 102; the inner cover 202 is provided with a second limiting groove 2023, and the movable arm 402 of the torsion spring 4 is provided in the second limiting groove 2023 to abut against the inner cover 202.

[0101] In the above embodiment, the first limiting groove 1024 and the first limiting groove 1024 are respectively used to fix the fixed arm 401 and the movable arm 402 of the torsion spring 4 to ensure that the torsion spring 4 is stably installed.

[0102] Specifically, since the fixed arm 401 and movable arm 402 of the torsion spring 4 have a restoring force, the structural components can be made to abut against each other through the restoring force. Therefore, the first limiting groove 1024 is set as an open groove, and the opening direction of the open groove is opposite to the restoring force direction of the fixed arm 401 and movable arm 402.

[0103] In some embodiments, such as Figure 6 , Figure 7 , Figure 13 As shown, there are two torsion springs 4, which are respectively sleeved on both ends of the hinge shaft 3, so that the two torsion springs 4 are located on both sides of the mounting cavity 1022, so that the middle part of the mounting cavity 1022 forms a wiring space 5.

[0104] In the above embodiment, two torsion springs 4 are arranged near the two ends of the mounting cavity 1022, and sufficient wiring space 5 is reserved in the middle of the mounting cavity 1022 to facilitate the arrangement of the wire harness 6.

[0105] Specifically, the electrical structure of the support ring 102 is electrically connected to the electrical structure of the inner cover 202 through the wiring harness 6. Therefore, the two torsion springs 4 are placed close to both ends of the mounting cavity 1022, thereby reserving sufficient wiring space 5 in the middle of the mounting cavity 1022.

[0106] In some embodiments, such as Figure 4 As shown, the open-lid cooking appliance is a rice cooker.

[0107] Open-lid cooking appliances can also be set up as electric pressure cookers, etc.

[0108] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
