Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cooking appliances, and in particular to a cooking device with flap damping. Background Art
[0002] At present, the lids of cooking appliances such as rice cookers on the market are usually equipped with hinge springs and resistance silicone. The elastic force of the hinge springs drives the lid to remain open when it is in the open state, and the lid will not be affected by its own gravity and will automatically close in the event of accidental touch or shaking back and forth, so as to prevent accidents such as pinching fingers.
[0003] However, in the process of innovation and cost reduction and efficiency improvement, some cooking appliances have eliminated hinge springs and resistance silicone. This can cause the lid of an open pot to automatically close due to its own weight if accidentally touched or swung back and forth, significantly increasing the risk of accidents such as fingers being pinched by the cooking appliance. Therefore, how to prevent the lid of a cooking appliance from automatically closing due to its own weight without relying on hinge springs and resistance silicone has become an urgent problem.

[0016] In summary, the cooking device with flap damping provided by this application has the following technical effects:
[0017] By rotating the first damping member following the upper cover, the first damping member is driven to transitionally cooperate with the second damping member when the angle between the upper cover and the pot body is angle α, thereby achieving a damping effect, thereby increasing the resistance of the upper cover to rotation around the hinge axis in the direction of closing the pot body, preventing the upper cover from automatically closing under the action of its own weight, effectively avoiding the phenomenon of the upper cover pinching fingers, and improving the safety performance of the device.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.
[0030] See Figure 1 and Figure 6, the present application discloses a cooking device with flip-lid damping. In this embodiment, the cooking device with flip-lid damping includes a pot body 1, an upper cover 2, a first damping member 3 and a second damping member 4. In some embodiments, the upper cover 2 is hinged to the pot body 1, and the upper cover 2 can rotate around the hinge axis in the direction of opening or closing the pot body 1; the first damping member 3 is provided on the upper cover 2, and can rotate with the upper cover 2; the second damping member 4 is provided on the pot body 1, and when the angle between the upper cover 2 and the pot body 1 is an angle α, the first damping member 3 and the second damping member 4 are transitionally matched to increase the resistance of the upper cover 2 to the rotation around the hinge axis in the direction of closing the pot body 1. Optionally, it is defined that when the upper cover 2 covers the pot body 1, the angle between the upper cover 2 and the pot body 1 is 0, see Figure 4 When the upper cover 2 rotates upward about the hinge axis, the upper cover 2 rotates about the hinge axis in the direction of opening the pot body 1. When the upper cover 2 rotates downward about the hinge axis, the upper cover 2 rotates about the hinge axis in the direction of closing the pot body 1. Preferably, the first damping member 3 rotates along with the upper cover 2, driving the first damping member 3 to transitionally cooperate with the second damping member 4 when the angle between the upper cover 2 and the pot body 1 is angle α, thereby achieving a damping effect, thereby increasing the resistance to the upper cover 2 rotating about the hinge axis in the direction of closing the pot body 1, preventing the upper cover 2 from automatically closing under the action of its own weight, effectively avoiding the phenomenon of the upper cover 2 pinching fingers, and improving the safety performance of the device.
[0031] See Figure 4 、 Figure 5 and Figure 6In some embodiments, when the angle between the upper cover 2 and the pot body 1 is less than angle β, the first damping member 3 and the second damping member 4 are loosely engaged. Preferably, when the angle between the upper cover 2 and the pot body 1 is less than angle β, the first damping member 3 and the second damping member 4 are loosely engaged, so that the resistance to the upper cover 2 rotating about the hinge axis in the direction of closing the pot body 1 is very small or there is no resistance. In this way, the upper cover 2 can rotate about the hinge axis in the direction of closing the pot body 1 under the action of its own weight. Optionally, if the angle β is greater than the angle α, then when the angle between the upper cover 2 and the pot body 1 is greater than the angle α, the first damping member 3 and the second damping member 4 are clearance-fitted, and the resistance to the upper cover 2 rotating around the hinge axis in the direction of closing the pot body 1 is very small or there is no resistance. The upper cover 2 can rotate around the hinge axis in the direction of closing the pot body 1 under the action of its own weight until the angle between the upper cover 2 and the pot body 1 is angle α, then the first damping member 3 and the second damping member 4 are converted from clearance-fitted to transition-fitted to achieve a damping effect, thereby increasing the resistance to the upper cover 2 rotating around the hinge axis in the direction of closing the pot body 1, preventing the upper cover 2 from automatically closing under the action of its own weight, effectively avoiding the phenomenon of the upper cover 2 pinching fingers, and improving the safety performance of the equipment.
[0032] See Figure 4 、 Figure 5 and Figure 6 In some embodiments, the angle α is greater than the angle β. Preferably, when the angle between the upper cover 2 and the pot body 1 is angle α, the first damping member 3 and the second damping member 4 are in transition fit, and the resistance to the upper cover 2 rotating about the hinge axis in the direction of closing the pot body 1 is relatively large. At this time, the upper cover 2 cannot automatically close under the action of its own weight, and the user needs to apply force to the upper cover 2 to continue to drive the upper cover 2 to rotate about the hinge axis in the direction of closing the pot body 1. Until the angle between the upper cover 2 and the pot body 1 is less than angle β, the first damping member 3 and the second damping member 4 are converted from a transition fit to a clearance fit, so that the resistance to the upper cover 2 rotating about the hinge axis in the direction of closing the pot body 1 is very small or there is no resistance, and the upper cover 2 can rotate about the hinge axis in the direction of closing the pot body 1 under the action of its own weight.
[0033] See Figure 5In some embodiments, the angle β is greater than or equal to 67°, and the angle β is less than or equal to 77°. Optionally, the angle β is any one of 67° to 77°. Preferably, the angle β is 72°. In this embodiment, when the user manually applies a force to the upper cover 2 to drive the upper cover 2 to rotate around the hinge axis in the direction of closing the pot body 1 until the angle between the upper cover 2 and the pot body 1 is less than 72°, the first damping member 3 and the second damping member 4 are converted from a transition fit to a clearance fit, and the resistance to the upper cover 2 rotating around the hinge axis in the direction of closing the pot body 1 is very small or there is no resistance. In this way, the upper cover 2 can rotate around the hinge axis in the direction of closing the pot body 1 under the action of its own weight.
[0034] See Figure 2 and Figure 5 In some embodiments, a first guide surface 31 is provided at the upper end of the first damping member 3. The first guide surface 31 is used to guide the first damping member 3 to transitionally fit with the second damping member 4. Preferably, the first damping member 3 rotates along with the upper cover 2. In this way, when the upper cover 2 rotates about the hinge axis in the direction of opening the pot body 1, when the angle between the upper cover 2 and the pot body 1 approaches the angle β, the first guide surface 31 can cooperate with the second damping member 4 to guide the first damping member 3 and the second damping member 4 from a clearance fit to a transitional fit, thereby avoiding interference between the upper end of the first damping member 3 and the inner side of the second damping member 4, and ensuring that the upper cover 2 can rotate under the force applied by the user.
[0035] See Figure 2 、 Figure 3 、 Figure 6 and Figure 7 In some embodiments, a first avoidance surface 32 is provided at the lower end of the first damping member 3, and a second avoidance surface 41 is provided at the outer side of the second damping member 4. The first avoidance surface 32 and the second avoidance surface 41 cooperate to form a avoidance gap. Optionally, the outer side of the second damping member 4 is the side away from the inner pot of the pot body 1, and the inner side of the second damping member 4 is the side close to the inner pot of the pot body 1. Preferably, the first damping member 3 rotates along with the upper cover 2. In this way, when the upper cover 2 rotates around the hinge axis in the direction of closing the pot body 1, when the angle between the upper cover 2 and the pot body 1 is close to the angle α, the first avoidance surface 32 and the second avoidance surface 41 cooperate to form a avoidance gap, thereby avoiding interference between the lower end of the first damping member 3 and the outer side of the second damping member 4, thereby ensuring that the upper cover 2 can rotate.
[0036] See Figure 2In some embodiments, the first damping member 3 includes a rib 33 disposed on a side of the upper cover 2 near the hinge axis, the first guide surface 31 disposed at the upper end of the rib 33, and the first avoidance surface 32 disposed at the lower end of the rib 33. Preferably, the rib 33 serves as the first damping member 3, thereby enhancing the strength and rigidity of the upper cover 2, allowing the upper cover 2 to withstand greater external forces and optimizing the structure of the upper cover 2. Furthermore, the rib 33 is integrally formed with the upper cover 2, effectively reducing the number of parts.
[0037] See Figure 2 、 Figure 4 and Figure 7 In some embodiments, the invention further comprises a baffle 5, which is disposed on a side of the upper cover 2 near the hinge axis. A stepped surface 42 is disposed on the inner side of the second damping member 4. When the angle between the upper cover 2 and the pot body 1 is angle γ, the baffle 5 abuts against the stepped surface 42. Optionally, the baffle 5 is connected to the lower end of the upper cover 2. Optionally, the ribs 33 and the baffle 5 are arranged vertically. Preferably, the ribs 33 and the baffle 5 can rotate with the upper cover 2. In this way, when the upper cover 2 rotates about the hinge axis in the direction of opening the pot body 1, when the angle between the upper cover 2 and the pot body 1 is angle γ, the baffle 5 abuts against the stepped surface 42, driving the baffle 5 and the stepped surface 42 to interfere with each other, thereby preventing the upper cover 2 from continuing to rotate about the hinge axis in the direction of opening the pot body 1. In other words, the maximum angle between the upper cover 2 and the pot body 1 is angle γ.
[0038] See Figure 2 、 Figure 4 and Figure 7 In some embodiments, the angle γ is greater than 94° and the angle γ is less than or equal to 101°. Optionally, the angle γ is any one of 94° to 101°. Preferably, the angle γ is 96°. In this embodiment, when the upper cover 2 rotates around the hinge axis in the direction of opening the pot body 1 to an angle of 96° with the pot body 1, the blocking piece 5 abuts and interferes with the step surface 42, preventing the upper cover 2 from continuing to rotate around the hinge axis in the direction of opening the pot body 1, thereby limiting the maximum rotation range of the upper cover 2 and preventing the upper cover 2 from rotating too much when opening the cover, thereby preventing the hinge axis or gas components from being damaged.
[0039] See Figure 4 、 Figure 5 、 Figure 6 and Figure 7In some embodiments, the angle α is greater than or equal to 84°, and the angle α is less than or equal to 94°. Optionally, the angle α can be any one of 84° to 94°. Preferably, the angle α is 89°, 90°, etc. Preferably, in the process of the upper cover 2 rotating around the hinge axis in the direction of opening the pot body 1, when the angle between the upper cover 2 and the pot body 1 is angle α, the first damping member 3 and the second damping member 4 are converted from a transition fit to a clearance fit, and the resistance to the rotation of the upper cover 2 around the hinge axis in the direction of opening the pot body 1 is very small or there is no resistance; in the process of the upper cover 2 rotating around the hinge axis in the direction of closing the pot body 1, when the angle between the upper cover 2 and the pot body 1 is angle α, the first damping member 3 and the second damping member 4 are converted from a clearance fit to a transition fit, achieving a damping effect, thereby increasing the resistance to the rotation of the upper cover 2 around the hinge axis in the direction of closing the pot body 1, preventing the upper cover 2 from automatically closing under the action of its own weight, effectively avoiding the phenomenon of the upper cover 2 pinching fingers, and improving the safety performance of the equipment.
[0040] See Figure 4 、 Figure 5 、 Figure 6 and Figure 7In some embodiments, when the upper cover 2 rotates around the hinge axis in the direction of opening the pot body 1, when the angle between the upper cover 2 and the pot body 1 is less than the angle β, the first damping member 3 and the second damping member 4 are clearance-fitted, so that the resistance to the rotation of the upper cover 2 around the hinge axis in the direction of closing the pot body 1 is very small or there is no resistance. When the angle between the upper cover 2 and the pot body 1 is equal to the angle β, the first damping member 3 and the second damping member 4 are converted from clearance fit to transition fit, and the resistance to the rotation of the upper cover 2 around the hinge axis in the direction of opening the pot body 1 is reduced. The force is large, preferably, the angle β is preferably 72°, when the angle between the upper cover 2 and the pot body 1 is greater than the angle α, the first damping member 3 and the second damping member 4 are converted from a transition fit to a clearance fit, and the resistance of the upper cover 2 to rotate around the hinge axis in the direction of opening the pot body 1 is very small or there is no resistance, preferably, the angle α is 89°, when the angle between the upper cover 2 and the pot body 1 is an angle γ, the baffle 5 abuts against the step surface 42 to drive the baffle 5 and the step surface 42 to interfere with each other, preventing the upper cover 2 from continuing to rotate around the hinge axis in the direction of opening When the upper cover 2 is rotated in the direction of closing the pot body 1 around the hinge axis, the maximum angle between the upper cover 2 and the pot body 1 is angle γ, preferably, angle γ is preferably 96°; when the upper cover 2 is rotated around the hinge axis in the direction of closing the pot body 1, when the angle between the upper cover 2 and the pot body 1 is angle α, optionally, the angle α can be 90°, the first damping member 3 and the second damping member 4 are converted from clearance fit to transition fit, and the resistance of the upper cover 2 to rotate around the hinge axis in the direction of closing the pot body 1 is large, thereby achieving a damping effect, thereby increasing the resistance of the upper cover 2 to rotate around the hinge axis in the direction of closing the pot body 1. The resistance to rotation in the direction of closing the pot body 1 is eliminated to prevent the upper cover 2 from automatically closing under the action of its own weight. When the angle between the upper cover 2 and the pot body 1 is less than or equal to the angle β, the first damping member 3 and the second damping member 4 are converted from a transition fit to a clearance fit. The resistance to rotation of the upper cover 2 around the hinge axis in the direction of opening the pot body 1 is very small or there is no resistance. The upper cover 2 can rotate around the hinge axis in the direction of closing the pot body 1 under the action of its own weight. In this way, the phenomenon of the upper cover 2 pinching fingers is effectively avoided, thereby improving the safety performance of the equipment.
