Problems solved by technology

[0012] The shortcoming of above-mentioned existing electric cooker is: when opening pot cover 14, hinge spring 30 exerts very large rotational driving force to pot cover 14
Therefore, when the opening angle of the pot cover 14 exceeds a certain position (about 90°), the overturning phenomenon easily occurs due to the inertia of the pot cover 14
At this time, the pot cover 14 will drive the whole electric cooker to shake violently, and even lift the front part of the electric cooker, so that the whole electric cooker will be impacted, which will not only easily cause damage to the parts of the electric cooker, but also cause serious damage to the user. It is inconvenient to come, which reduces the credibility of the rice cooker

Embodiment approach 1

[0040] image 3 , Figure 4 and Figure 5 As shown, the electric rice cooker of this embodiment includes: a body 12, a rice cooker 10 installed in the body 12 and a pot cover 14; the rear end of the pot cover 14 is combined with the body 12 through a hinge mechanism 20 and a damping mechanism. Above, the pot cover 14 can open / close the main body 12 by rotating with the hinge shaft 23 as the rotation axis.

[0041] Described pot cover 14 comprises two parts of pot cover shell 16 and pot cover inner shell 15.

[0042] The hinge mechanism 20 includes: a hinge shaft 23, a hinge bracket 21, a hinge spring 30 and a fixing hole 24; the hinge bracket 21 is protrudingly formed on the lid inner shell 15, and the hinge bracket 21 A hinge shaft hole 26 is formed; the two ends of the hinge shaft 23 are respectively inserted into the hinge shaft hole 26; the spring body 31 of the hinge spring 30 is sleeved on the hinge shaft 23, and the front end 33 of the hinge spring 30 is inserted and...

Embodiment approach 2

[0051] like Image 6 As shown, the damping mechanism of the rice cooker of this embodiment includes: a cylinder 412 fixed at the rear end of the rice cooker body 12, a piston 413 arranged in the cylinder 412 and capable of reciprocating movement, and a piston 413 formed at the bottom of the cylinder 412 for discharging air. Gas exhaust mechanism 414 and rack and pinion mechanism 430 for converting the rotary motion of pot cover 14 relative to hinge shaft 23 into reciprocating motion of piston 413 .

[0052] The rack-and-pinion mechanism 430 includes: a rod-shaped rack 432 with one end fixed on the piston 413 and a gear 431 arranged at the rear end of the pot cover 14 , the gear teeth of the gear 431 mesh with the rack 432 .

[0053] Other parts of the electric rice cooker of this embodiment are the same as Embodiment 1.

[0054] The working process of the damping mechanism of the electric rice cooker of the present embodiment will be described below:

[0055] When the pot co...

Embodiment approach 3

[0059] like Figure 7 As shown, the exhaust mechanism 414 in the damping mechanism of the electric rice cooker in this embodiment is the exhaust hole 416 provided on the piston 413 .

[0060] Other parts of the electric rice cooker of this embodiment are the same as Embodiment 1 or Embodiment 2.

Abstract

Disclosed is an electric cooker, comprising a main body, a pot mounted on the main body, a hinge mechanism, a pot cover and a damping mechanism. The rear end of the said pot cover can be combined with the main body by means of the hinge mechanism and the damping mechanism and the pot cover can open / close the main body by pivoting on the hinge axis, In the process for opening the pot cover, damping force is exerted by the said damping mechanism. The beneficial effect of the invention lies in that the damping force adjustable damping mechanism for the cooker opening can effectively avoids the excess pot cover opening, the anterior part of the cooker being lift up and the whole cooker vibration occurrence.

Description

technical field [0001] The invention relates to an electric rice cooker. Background technique [0002] An electric rice cooker is a household appliance that uses electric energy as a heating source to cook rice. It can maintain a high-pressure state in the rice cooker, so that the temperature in the rice cooker is higher than the boiling point of water, thereby quickly completing the cooking operation. [0003] like figure 1 As shown, the existing electric rice cooker comprises: a body 12, a rice cooker 10 installed in the body 12 and a pot cover 14; The shaft rotates to open / close the body 12 . [0004] Described main body 12 is provided with the electric heating device that is used for heating rice cooker 10; Described pot cover 14 is provided with the exhaust valve (not shown) that is used for regulating rice cooker internal pressure; Described electric heating device includes : working coil 16 and heat preservation electric heating plate (not shown in the figure), whe...
