Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Preferred embodiment:
This preferred embodiment discloses a kind of cooking apparatus, especially a kind of electric cooker, and cooking apparatus includes but is not limited to electricity
Rice cooker can also be electric pressure cooking saucepan or the product of uncapping of other purposes.
Such as Fig. 1, a kind of electric cooker, including passing through articulated shaft 3 hinged upper cover 1 and apparatus body 2 (that is, hinged pot cover
And cooker body) and torsion spring member.Upper cover 1 includes the inner cover and outer cover that are interlocked, one end of torsion spring member be fixed in cover, separately
One end is fixed in cooker body.
Specifically, as shown in Fig. 2, torsion spring member includes the first torsional spring 4 and the second torsional spring 5, the first torsional spring 4 and the second torsional spring
5 installation direction on the contrary, and the upper end of the first torsional spring 4 and the second torsional spring 5 connect respectively with inner cover, the first torsional spring 4 and second is turned round
The lower end of spring 5 is connect with cooker body respectively, and in upper cover opening procedure, the first torsional spring 4 applies thrust to upper cover 1, can be fast by upper cover 1
Speed flicks, and the second torsional spring 5 applies pulling force to upper cover 1, and can delay upper cover 1 flicks speed, which solves existing electric meal
There is take-off when opening in the upper cover of pot, uncap steady, and will not be generated because of unbalance stress double swerve even and its
He rubs at component, greatly improves the service life of complete machine.
In the present embodiment, the first torsional spring 4 is positive installation, and the second torsional spring 5 is reversed installation, and the first torsional spring 4 and second is turned round
The quantity of spring 5 is both preferably two, and two the first torsional springs 4 and two the second torsional springs 5 are symmetrically set with the central axes of pot body 2 respectively
It sets, two the second torsional springs 5 are located between two the first torsional springs 4.Since the elastic force needed for opening process of upper cover 1 is larger, choosing
It selects two the first torsional springs 4 and elastic force is shared to the line footpath that can make the first torsional spring 4 and the opposite reduction of central diameter, in case the first torsional spring 4 accounts for
According to tangential space it is too many, reasonable in design, attractive appearance.
The quantity of above-mentioned first torsional spring 4 and the second torsional spring 5 is only preferred amount, can also be carried out according to actual use demand
Setting, for example, respectively setting one, three or more, different numbers can also be set by the first torsional spring 4 and the second torsional spring 5,
It can satisfy and use function.
Under normal conditions, the first torsional spring 4 is identical with the line footpath of the second torsional spring 5, the central diameter of the first torsional spring 4 and the second torsional spring 5
Also identical, but it is also possible to be configured according to the size of elastic force and requirement.
Installation requirement: when upper cover 1 is closed, the first torsional spring 4 and the second torsional spring 5 is made to be in the state of being twisted (that is, having bullet
Property deformation), alternatively, being in the first torsional spring 4 is twisted state, the second torsional spring 5 is in Spontaneous release state (that is, nonelastic shape
Become).When upper cover 1 is opened to 90 °, the first torsional spring 4 and the second torsional spring 5 are in the state of being twisted, and the torque of the first torsional spring 4 is equal to
The torque of second torsional spring 5.
Upper cover 1 is opened fully to 90 ° of detailed process and is analyzed as follows by being closed to:
When upper cover 1 is closed, the torque of the first torsional spring 4 is greater than the torque of the second torsional spring 5, and (the second torsional spring 5 is in Spontaneous release
Torque is the sum of the torque zero) generated with the gravity of upper cover 1 when state, and the opening speed of upper cover 1 is zero at this time；
When upper cover 1 continues to open, the torque of the first torsional spring 4 is gradually reduced, the torque of the second torsional spring 5 and the weight of upper cover 1
The sum of the torque that power generates is gradually increased, until the torque of the first torsional spring 4 is equal to the torque of the second torsional spring 5 and the gravity of upper cover 1
The sum of torque of generation, at this point, the opening speed of upper cover 1 reaches maximum value；
When upper cover 1 continues to open, the sum of the torque that the torque of the second torsional spring 5 and the gravity of upper cover 1 generate is greater than first
The opening speed of the torque of torsional spring 4, upper cover 1 is gradually reduced by maximum, when upper cover 1 is opened to 90 °, the opening speed of upper cover 1
It is decreased to zero, at this point, the torque that gravity generates is zero, the torque of the first torsional spring 4 is equal to the torque of the second torsional spring 5, in upper cover 1
In opening procedure, bow-backed phenomenon will not occur for upper cover, solve existing electric cooker or other hunchbacks existing for product of uncapping are asked
