Description
Technical field
The utility model relates to a kind of electrical heating pressure means, particularly electric pressure cooking saucepan, pressure soy milk grinder and pressure coffee machine etc. by pressure controlled electrical heating pressure means.
Background technology
At present, the mode of electrical heating pressure means controlled pressures such as electric pressure cooking saucepan, pressure soy milk grinder and pressure coffee machine is mainly 3 kinds:
1. great majority are that what to adopt is " rectifying " formula structure (can consult Chinese patent CN1060020A) on the market, and its pressure switch is installed on the outer pot wall, and outer pot bottom employing " plate " formula spring, " U " shape spring, " bridge " shape spring, " V " shape spring.Elastic deformation amount with upper spring is little, and complex manufacturing technology, the cost height; When normally using, there is abnormal sound (to be head it off, adopt the shell fragment both sides to increase the friction that produces when plain cushion reduces the spring pressurized mostly, just increased manufacturing cost virtually), the complete machine manufacturing process is loaded down with trivial details, start to control many weak points such as pressure transient, spring is depleted easily, spring is short serviceable life; The pressure control deviation of utensil is big, is difficult to accurate control in cooking process, makes food can not reach desirable culinary art effect.
2. rigid structure is to utilize the elastic deformation of enclosure body intensity to reach the control purpose.The processing and manufacturing accuracy requirement of key components and partss such as interior pot and outer pot is very high, technology difficulty and complexity in the parts process of manufacture have been increased, the rejection rate height, increased the manufacturing cost of product virtually, and in user's use, producing gas leakage because of parts distortion, precision reduce easily, there is very big labile factor in its pressure control.
3. temperature control mode, it is to utilize thermistor to pass through temperature in the detection receptacle, is converted to pressure by chip again, its pressure control error is big.This appliances can only be done conjuncted structure, can not do the branch body structure, and the market of product line is in the too little demand that can not satisfy market of design time space.
The utility model content
Above-mentioned deficiency at three kinds of electrical heating pressure means controlled pressure modes, above-mentioned for thoroughly solving because of factors such as complete machine cost of manufacture height, parts complex manufacturing technology and quality instabilities, technical problem to be solved in the utility model is a kind of carries out pressure controlled electrical heating pressure means by flexible member distortion generation displacement, its flexible member have the elastic compression amount big, support steadily, have no abnormal sound during operate as normal, aspect pressure control very sensitive accurately.
In order to solve the problems of the technologies described above, what the utility model proposes a kind ofly produces displacement by flexible member distortion and carries out pressure controlled electrical heating pressure means, comprise container cover, O-ring seal, container, outer pot, heating plate, flexible member and power switch, its innovative point is, flexible member is enclosed within on the heating plate leg, by screw heating plate, flexible member and outer pot are fixed, heating plate is connected with outer pot elasticity; An interior pot bottom surface is attached on the cambered surface of heat-generating disc, and the tooth of buckleing of the lid tooth of pot cover and outer pot fastens, and O-ring seal is enclosed within on the container cover, and O-ring seal is attached to respectively on container cover and the container; Power switch is fixed on the side of outer pot by support, and heat-generating disc and power switch are connected in the AC power.
Preferably, the utility model is above-mentioned to be produced displacement by flexible member distortion and carries out in the pressure controlled electrical heating pressure means, and flexible member is enclosed within supporting surface on the heating plate leg to be the plane or to support with plain cushion.
Preferably, the utility model is above-mentioned to be undertaken in the pressure controlled electrical heating pressure means by flexible member distortion generation displacement, flexible member has two or more pressure support faces and three or three above spiral fashion elastic arms, three or three above spiral fashion elastic arms are torn by the steel disc punching press and are formed, during compression elastic arm in the shape of a spiral direction method to motion.
Preferably, the utility model is above-mentioned to be undertaken in the pressure controlled electrical heating pressure means by flexible member distortion generation displacement, and the material of spiral fashion elastic arm is the spring slab.
Flexible member in the utility model electrical heating pressure means comprises two or more pressure support faces and three or three above spiral fashion elastic arms, three or three above spiral fashion elastic arms are torn and are formed by=steel disc punching press, elastic arm moves along the hand of spiral normal direction during compression, can directly contact with support housing with heating plate.The tear face of spring is done the normal direction helical motion when being under pressure, because the tear face end face is three or three above facets, its friction factor is minimum, therefore can not produce abnormal sound, and the structure that is better than in the above-mentioned industry other serviceable life greatly, aspect pressure control very sensitive accurately.Advantage such as the utility model also has economical with materials, processing cost is low, manufacturing process is simple, elasticity stable, decrement are big, remedied that decrements such as traditional disk spring, leaf spring are little, manufacturing process is complicated, and need to increase pad and strengthen supporting surface, shortcomings such as processing cost height.
With respect to prior art, the utility model is by " snowflake " shape strong elastic flexible member, increased the displacement stroke of switch motion, switch is directly installed on the outer pot wall, and the displacement induction point of the installation site of switch and switch sensing mechanism is positioned on the same circumference, the distortion of outer pot can not influence the displacement of switch, thereby has thoroughly solved the problem that causes the working pressure decay of electric pressure cooker because of the permanent strain of outer pot.The utility model also forms the Pneumatic differential pressure type sealing by O-ring seal when producing air pressure between interior pot and the pot cover in pot, reduce special flexible member and increased the stroke of inductive displacement under the certain pressure, and the mounting means that switch is special, reduced the precision of parts processing and final assembly, improved the control accuracy of pressure and the sensitivity of induction, got rid of product and in use produced the working pressure decay that plastic yield causes because of outer pot.
