The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1-Fig. 7, the steam valve structure of this electric cooker comprises the valve body that is arranged on the pot cover 4, and valve body is assembled by valve seat 1 that has steam vent 14 and valve gap 3.The peristome periphery of valve seat 1 is provided with outside flange 11, flange is provided with three valve seat fixing holes 12, offer the through hole 41 that is complementary with valve seat 1 size, shape on the pot cover 4, through hole and valve seat fixing hole 12 corresponding positions are provided with pot cover fixing hole 42, securing member 7 passes pot cover fixing hole 42 and valve seat fixing hole 12 from the below of pot cover 4, valve seat 1 is fixed on the pot cover 4.Securing member 7 is rivet or screw.The material of pot cover 4 is an aluminum alloy materials, the surperficial punch forming 2-10 of pot cover 4 boss 43, and difform floral designs of its one-tenth capable of being combined or pictorial trademark, the unique outlook novelty, the while can be improved the structural rigidity of pot cover 4 again.
A projection 34 is extended at the middle part of valve gap 3, and described projection is interior sky, and projection is provided with steam channel 31 and six s' drainage hole 32 in 34; Pressure ball 2 is crimped on (referring to Fig. 2) on the steam channel 31.Be provided with diagonal bar 35 between the inwall of projection 34 and the steam channel 31, diagonal bar 35 is around setting, and diagonal bar is inclined upwardly towards inwall by the upper end of steam channel 31.Distance between the diagonal bar 35 can not fall down with pressure ball 2 and be advisable; Diagonal bar 35 plays the support and the guide effect thereof of pressure ball 2, and the quantity of drainage hole is generally 2-10.
The outer wall 33 of projection 34 passes pot cover 4, socket-connects with valve seat 1; Be provided with sealing ring 5 between valve gap 3 and the valve seat 1.The top of sealing ring 5 is provided with convex tendon 51, and valve seat 1 is provided with the holddown groove 13 that is complementary with convex tendon 51.The outer wall 33 of sealing ring 5 is provided with clearance position 53, and valve seat 1 is provided with projection 15 with clearance position 53 corresponding positions, and the clearance position 53 of sealing ring connects and fixes with the projection 15 of valve seat 1, prevents that sealing ring 5 is subjected to displacement.The inwall of sealing ring 5 extends the screens 52 of ring-type, and it is similar inverted U-shaped that the cross section of screens is.Projection 34 on screens 52 and the valve gap 3 connects and fixes mutually, utilizes the plastic deformation of screens 52 that valve gap 3 is fixed in the valve seat 1, and sealing ring 5 plays sealing and fastening effect.
The bottom of valve gap 3 is provided with sealing gasket 6, sealing gasket 6 is provided with the exhaust hole 52 that connects with steam channel 31, and being provided with the fixed leg 61 that is complementary with drainage hole 32, fixed leg can be arranged in to be located on the drainage hole on the drainage hole 32, is used for sealing drainage hole 32; Drainage hole 32 is arranged between two diagonal bars 35.The material of sealing gasket 6 is a silica gel material, so it has the characteristics of good sealing effect.
Operation principle of the present invention is: in the process of cooking, the steam of pot in the body enters from steam channel 31, when steam is pushed pressure ball 2 open, owing to the deadweight of pressure ball 2 forms certain resistance, stew this moment in the body because steam is obstructed when discharging, and form the certain air pressure that exists in pot body.When the pressure rises in pot body arrived certain force value, steam can promote on the pressure ball 2 to moving, then by steam vent 14 discharges of steam channel 31 to valve seat 1; When the air pressure in pot body dropped to certain force value, pressure ball 2 resetted along diagonal bar 35, and pressure ball 2 is blocked steam channel 31 once more.
When producing steam in pot body, sealing gasket 6 is subjected to the thrust of steam expansion, and valve seat 1 drainage hole 32 is clogged, and the interior steam of body that prevents to stew leaks.When steam along steam channel 31 in the external discharge process of pot, produce ponding in the projection 34 that can be on valve gap 3, this moment, vapor action disappeared in the thrust of sealing gasket 6, ponding can be from drainage hole 32 discharges of valve gap 3.
