Description
Technical field
The present invention relates to the bindiny mechanism of the steam releasing cap that a kind of electric pressure steam discharge pipe venthole do not hold.
Background technology
Electric pressure is to be the cooking apparatus of heating source with the electric energy, and its utilization keeps the high pressure in the pot and makes the interior vapor (steam) temperature of pot than higher under the atmospheric pressure, thereby finishes culinary art fast.
Fig. 1 is the longitdinal cross-section diagram of electric pressure structure of the prior art, and Fig. 2 is the longitdinal cross-section diagram of the bindiny mechanism of steam releasing cap of the prior art.
As shown in Figure 1, electric pressure by pot (10), in load onto the above-mentioned body casing of body casing (12), folding (12) of stating pot (10) pot cover (14), be used for heating or the steam discharging device that makes the electric installation of pot (10) insulation and be used for adjusting the pressure in the pot (10) constitutes.
Above-mentioned electric installation is incubated the side heater formations such as (18) of heating in the time of can producing faradic actuating coil (16) and insulation by the inside that is installed in body casing (12), when cooking.
Thereby steam discharging device comprise controlled portion control and open make solenoid valve (20) that the pressure in the pot (10) reduces and at pot (10) thus in pressure openly when surpassing certain value prevent that the pressure in pot (10) from rising so high and keeping simultaneously the balanced valve (30) of certain pressure.
Above-mentioned balanced valve (30) has perforation pot cover (14) and the pressure hammer (34) of the end of the steam discharge pipe (32) installed and venthole one side that is installed in above-mentioned steam discharge pipe (32) from pot cover (14) outside constitutes, the inside of above-mentioned pressure hammer (34) is provided with the valve pin (35) that the upper end to the steam passing away (32a) of steam discharge pipe (32) opens and closes, and has also formed to be used for the exhaust hole (not shown) of exhaust steam below it.
As shown in Figure 2, above-mentioned solenoid valve (20) is by being connected with the top panel (141) of pot cover (14), inside have exhaust steam steam passing away (22a) thus with the steam discharge pipe (22) of the external communications of the inside of pot (10) and loam cake (142), open and close the dividing plate (24) of steam hole (23), the piston (26) that links together with aforementioned barriers (24) and the solenoid core (28) that is used to drive above-mentioned piston (26) constitute.
How the following describes aforesaid existing electric pressure cooks.
At first, by actuating coil (16) vortex induction is arrived on the pot (10), pot (10) is slowly heated under the effect of eddy current, and the water that makes the grain of rice absorb moisture is thus sent out process.After the water of a period of time is sent out process, through with the heating process of high temperature heating kettle and enter the boiling process that promotes the thin rice gruel temperature rapidly.
At this moment, since the upper end of pot (10) by lock ring device (not shown) make itself and top panel (141) below be close together, and the solenoid valve (20) and the balanced valve (30) that constitute steam discharging device keep closed state, therefore if begin to enter the fluidized state of thin rice gruel boiling, then pot (10) internal pressure can be because of having produced steam than atmospheric pressure height.
Because along with the increase of pot (10) internal pressure, the temperature of thin rice gruel rises to the high temperature of boiling point than under atmospheric pressure, so rice grain can become ripe quickly.
After the boiling process of a period of time finishes, process by coil heats is interrupted, carry out the process of cooking rice over a slow fire of a period of time in this state, after the process of cooking rice over a slow fire finishes, effect by solenoid valve (20) with pot (10) thus in steam discharge pressure reduced, enter in this state by heater (18) and carry out low-temperature heat so that pot (10) keeps the insulating process of certain temperature.
The following describes aforesaid electric pressure and be how to carry out pressure controlled.
If the pressure in gastronomical process in the pot (10) has surpassed standard value, will the steam in the pot (10) be discharged in right amount by opening above-mentioned balanced valve (30) so, therefore can prevent to rise so high on the pressure.
The driving of above-mentioned solenoid valve (20) is to realize by such mode: the power supply of solenoid core under the control of control part (not shown) (28) is switched on, under the effect of the magnetic force that above-mentioned solenoid core (28) produces, piston (26) makes dividing plate (24) produce strain, make steam hole (23) open thus, steam pot (10) is interior by the steam passing away (22a) of steam hole of opening (23) and the steam discharge pipe (22) that is communicated with it discharges.
In addition, end at the venthole (22b) of above-mentioned steam discharge pipe (22) is equipped with steam releasing cap (25), it not only has the effect that prevents by the opposing steam flow of steam discharge pipe (22) discharge, also has the effect of the direct row of the steam of discharging to the user that prevent.
Here, the structure of above-mentioned steam releasing cap (25) is: formed the threaded portion (not shown) respectively at the terminal outer surface of the venthole (22b) of above-mentioned steam discharge pipe (22) and the central lower of steam releasing cap (25), go up it can be dismantled by steam releasing cap (25) rotation being screwed onto steam discharge pipe (22), accumulate in foreign matter between steam releasing cap (25) and the steam discharge pipe (22) with removing.
But as if bindiny mechanism according to above-mentioned existing steam releasing cap (25), owing to respectively formed the threaded portion on the connecting portion of steam discharge pipe (22) and steam releasing cap (25), the increase of the number of working processes when therefore existing because of making causes the low problem of production efficiency.
When the user wants to remove the cleaning of foreign matter, with its dismounting or installation, therefore there is the cumbersome problem of dismounting of steam releasing cap (25) in addition owing to need to pass through rotation steam releasing cap (25).
Summary of the invention
In order to overcome the above-mentioned shortcoming that existing technology exists, the invention provides a kind of bindiny mechanism of steam releasing cap of electric pressure cooker, the easy and easy accessibility of its processing and manufacturing.
The technical solution adopted for the present invention to solve the technical problems is:
The invention provides a kind of bindiny mechanism of steam releasing cap of electric pressure cooker, electric pressure is provided with steam discharge pipe, solenoid valve and steam releasing cap, steam discharge pipe can discharge steam in the pot, solenoid valve optionally opens and closes steam discharge pipe, steam releasing cap is installed in venthole terminal and detachable of steam discharge pipe, the connecting portion of this steam releasing cap is provided with the rubber-like seal, be respectively equipped with projection and insertion groove on described steam discharge pipe venthole outer surface and the seal, projection and insertion groove can engage mutually, and projection and insertion groove constitute anti-drop structure.
The present invention utilizes the elasticity of above-mentioned seal and the mutual engaging of projection and insertion groove, and the present invention is simple in structure, processing and manufacturing is easy, and dismounting is easy, and can improve the slip-off preventing performance of steam releasing cap.
