Description

[0001] The present invention relates to a vapor discharge valve,

TECHNICAL FIELD The present invention relates to a steam discharge valve and, more particularly, to a steam discharge valve which can control the internal steam pressure of an electromagnetic cooker and which improves the reactivity of the steam opening / closing by an integrated case which simplifies parts and maintains the center of the plunger unit to be.

In an electric rice cooker that cooks rice, a steam discharge valve is provided between the cover and the lid to control the steam pressure.

Here, the steam discharge valve is a valve for shutting off the flow path so that the steam inside the rice cooker is not discharged to the outside when cooking or keeping warm by the control of the electromagnetic cooker, and discharging the steam through the control valve to be.

The principle of the steam discharge valve is that the steam is introduced and discharged by the selective coupling of the diaphragm to the orifice formed inside the body into which the steam is introduced. The case is joined to the upper part of the body, and the diaphragm is pressed by the plunger which is raised and lowered inside the case.

However, in the related art, the case is formed only in a lid shape, and its strength is weak, and reinforcement is often required with a separate frame or plate part.

In addition, conventionally, when the plunger is lifted and lowered, vibration is generated, and the pressure is not applied to the center of the diaphragm, so that the opening or closing of the orifice is not precisely performed.

Referring to FIG. 1, the steam discharge valve according to the present invention discharges steam in the rice cooker, and includes a body 10, a steam discharge tube 20, and a plunger unit 50, Is introduced into the body 10 and discharged to the steam discharge tube 20 by the operation of the plunger unit 50. Refer to Fig. 2 for the main structure and operation of the steam discharge valve.

2 is an exploded perspective view of a steam discharge valve according to an embodiment of the present invention.

2, the steam discharge valve according to the present invention includes a body 10, a steam discharge tube 20, a diaphragm 30, a holder 40, a plunger unit 50, a bobbin 60, a case 100, In the present invention, the structure and the coupling relationship of the case 100 and the holder 40 are characterized.

First, the body 10 is installed between the cover and the lid of the rice cooker, so that the steam inside the rice cooker is introduced. An orifice 11 is formed in the upper center of the rice cooker to introduce steam in the rice cooker into the space groove 13 and communicates with the side surface of the space groove 13 to discharge the steam. An outlet 12 is formed.

Here, the diaphragm 30 and the holder 40 are sequentially installed in the space groove 13.

Around the orifice 11, a plurality of protrusions 14 are formed radially along the periphery to support the lower portion of the diaphragm 30.

The steam discharge tube 20 communicates with the discharge port 12 on the outer surface of the body 10 to discharge the steam to the outside.

The diaphragm 30 is provided on a side surface of the space 10 of the body 10 and selectively contacts the orifice 11 to open or close the orifice 11.

Here, the diaphragm 30 is made of a rubber material having elasticity. The diaphragm 30 has a cylindrical seat portion which is in contact with the orifice and is openable and closable, and a disk-shaped portion which is pressed onto the plunger unit 50 at an upper portion of the seat portion And a flow portion.

The holder 40 is seated in the space groove 13 and rests on the diaphragm 30 to fix the diaphragm 30 to the body 10.

The holder 40 is formed in the shape of a disk having the same outer diameter as that of the diaphragm 30. Specifically, a plunger hole 42 through which the lower end of the plunger unit 50 passes is formed at the center, The guide groove 44 is formed.

The plunger hole 42 is formed to press the diaphragm 30 when the plunger unit 50 is lowered and the diaphragm 30 can selectively contact the orifice 11. [

The guide groove 44 is for transmitting a uniform pressing force to the holder 40 when the case 70 is coupled to the body 10, and will be described with reference to FIG.

The plunger unit 50 is provided on the holder 40 and inserted into the bobbin 60. The plunger unit 50 is lifted and lowered to allow the lower end of the plunger unit 50 to pass along the plunger hole 42 to press the diaphragm 30.

The plunger unit 50 includes a stopper 51, a plunger 52 mounted on the upper surface of the stopper 51 to be moved up and down, a spring 53 provided between the stopper and the plunger, And a shaft 54 installed through the stopper. When the electric power is applied, the plunger 52 is lowered and interlocked to lower the shaft 54. When the electricity is shut off, the spring 53 is restored.

The bobbin 60 surrounds the plunger unit 50 inwardly and the coil C (FIG. 3) is wound on the outer side. Such a coil C (FIG. 3) can cause the plunger unit 50 to be lifted or lowered by external application of electricity.

The case 70 receives the bobbin 60 and is coupled to the upper portion of the body 10.

At this time, the case 70 is integrally formed with the bobbin 60 by inmold injection.
