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
The present invention relates to a kind of electric cooker.
Background technology
Electric cooker be a kind of be the household electrical appliance that heating source is cooked with the electric energy, it can keep high pressure conditions in pot for cooking rice, make the temperature in the pot for cooking rice be higher than the boiling point of water, thereby finish the operation of cooking rapidly.
As shown in Figure 1, existing electric cooker comprises: body 12, be installed in pot for cooking rice 10 and pot cover 14 in the body 12; Described pot cover 14 is installed on the body 12 by linkage, and pot cover 14 is that body 12 can be opened/be closed to the axle rotation with the linkage.
Be provided with the electric calorifie installation that is used for heating pot for cooking rice 10 in the described body 12; Described pot cover 14 is provided with the exhaust steam valve (not shown) that is used for regulating the pot for cooking rice internal pressure; Described electric calorifie installation comprises: actuating coil 16 and insulation electric hot plate (not shown), when cooking operation, described actuating coil 16 energisings provide thermal source for pot for cooking rice 10, and when insulation, described insulation produces less heat with electric hot plate, keeps the temperature of pot for cooking rice 10.
The course of work of above-mentioned existing electric cooker is: after electric cooker energising started, described actuating coil 16 produced vortex flow pot for cooking rice 10 in, and pot for cooking rice 10 is heated by vortex flow, the interior food of heated pot for cooking rice 10 heating kettles, thus finish the operation of cooking.Carry out in the process in the operation of cooking, the inside line of pot cover 14 closely seals the opening of pot for cooking rice 10, exhaust steam valve is in closed condition simultaneously, therefore when the water in the pot for cooking rice 10 seethes with excitement, the steam that produces makes pot for cooking rice 10 pressure inside raise gradually, makes pot for cooking rice 10 pressure inside be higher than normal barometric pressure.
In addition, along with the rising of pot inner pressure, the boiling point of water also can be higher than the fluidizing point (100 degree) under the normal barometric pressure, and therefore rice can be boiled rapidly in the pot.When cooking the end of job, actuating coil 16 quits work, and the pressure in the pot for cooking rice 10 is maintained under original pressure, carries out vexed meal operation.After the vexed meal end of job, exhaust steam valve is opened, and the steam in the pot for cooking rice 10 is discharged, and pot inner pressure is reduced.Then, utilize insulation pot for cooking rice 10 to be kept at a certain temperature with heating plate.
Described linkage comprises: be used for that pot cover 14 rotatably is connected the hinge bracket 21 on the body 12 and apply the hinge spring 30 of rotary driving force to pot cover 14; Described hinge bracket 21 is formed on the inboard of pot cover 14, and the hinge axis 23 on the hinge bracket 21 is installed in the rear end of body 12.
As shown in Figure 2, described hinge spring 30 comprises following three parts: the rear end 32 of the spring main body 31 of coiled type, spring main body 31 1 ends and the front end 33 of spring main body 31 other ends; Hinge axis 23 on the described hinge bracket 20 inserts in the spring main body 31, and described rear end 32 is inserted and secured on the fixture on the body 12, and described front end 33 is inserted and secured on the pot cover 14.
Operation principle to the linkage of above-mentioned existing electric cooker is illustrated below:
When pot cover 14 is in when closing, front end 33 elastic bending deflections of hinge spring 30, and spring main body 31 is twisted.Meanwhile, be arranged on the hook (not shown) of pot cover 14 front ends and be meshed, thereby make pot cover 14 be locked in closed condition with restraint device (not shown) on being arranged on body 12.When need opening pot cover 14, only need to remove restraint device on the body 12 to the constraint of the hook of pot cover 14 front ends, under the effect of the restoring force of spring main body 31, front end 33 just can apply active force to pot cover 14, makes pot cover 14 open (dotting among the figure).
After pot cover 14 rotates to an angle (more than about 90 degree) unlatching, hinge bracket 21 is stuck in the upper end of body 12, the front end 33 of hinge spring 30 provides reverse elasticity power because of the variation of the windup-degree of spring main body 31 to pot cover 14, thereby pot cover 14 is stopped the rotation.
The shortcoming of above-mentioned existing electric cooker is: when opening pot cover 14,30 pairs of pot covers 14 of hinge spring apply very big rotary driving force.Therefore, when the opening angle of pot cover 14 surpasses certain position (about 90 °), because the upset over-education phenomenon takes place inertia pot cover 14 easily.At this moment, pot cover 14 can drive whole electric cooker generation and acutely rock, even the front portion of electric cooker is lifted, and whole electric cooker is impacted, and not only causes the damage of electric cooker parts easily, and makes troubles to the user, has reduced the credit worthiness of electric cooker.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the above-mentioned shortcoming of existing electric cooker, provides a kind of turn-on overshoot can prevent effectively that pot cover from opening the time, the electric cooker front portion is lifted and the electric cooker of phenomenons such as vibrations takes place whole electric cooker.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: electric cooker of the present invention comprises: body, be installed in intrinsic pot for cooking rice, linkage, pot cover and damping mechanism; The rearward end of described pot cover is combined on the body by linkage and damping mechanism, and pot cover is that body can be opened/be closed to the rotating shaft rotation with the hinge axis; In the pot cover opening process, described damping mechanism is to applying damping force.
Described damping mechanism comprises: be fixed on electric cooker body rear end cylinder, be arranged in the cylinder and piston that can be reciprocating, be formed on cylinder bottom be used for exhaust exhaust gear and be used for pot cover is converted to respect to rotatablely moving of hinge axis the reciprocating cam mechanism of piston; Described cam mechanism comprises: be formed at cam, connecting rod and connecting pin on the pot cover; Cam is connected with piston with connecting pin by connecting rod.
Described damping mechanism can also be, comprise: be fixed on electric cooker body rear end cylinder, be arranged in the cylinder and piston that can be reciprocating, be formed on cylinder bottom be used for exhaust exhaust gear and be used for pot cover is converted to respect to rotatablely moving of hinge axis the reciprocating pinion and rack of piston; Described pinion and rack comprises: an end is fixed on the bar-shaped tooth bar on the piston and is arranged on the gear of pot cover rear end, and the gear teeth of gear are meshed with tooth bar.
Described exhaust gear is the steam vent that is formed on cylinder bottom.
Described exhaust gear can also be for being arranged on the steam vent on the piston.
Described exhaust gear can also be the gap of leaving between piston and the cylinder inner wall.
The invention has the beneficial effects as follows: have the adjustable pot cover of damping force and open damping mechanism, turn-on overshoot in the time of can preventing effectively that pot cover from opening, the electric cooker front portion is lifted and phenomenons such as vibrations take place whole electric cooker.
