It is characterized by a configuration that does not flow into the solenoid basic components by.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is an illustration of an electric thermal pressure cooker to which the present invention is applied.

2 is a cross-sectional view of the steam discharge device applied in the present invention.

As shown in the figure, the configuration of the electric thermal pressure cooker includes a main body 10 in which an inner container 11 for charging a cooking object is embedded, a lid 2 coupled to an upper portion of the main body 10, and an inner portion thereof. The cooking chamber steam pressure of the vessel 11 is composed of a steam discharge means (A) made so that the solenoid 30 to control the steam discharge.

The configuration of the solenoid 30 corresponding to the steam discharging means (A), the coil 31 and the coil 31 to be induced by the coil cover 39 and the blocking member 40 to generate induced power, the interior of the coil 31 It is arranged to penetrate through the steam passage 32a and having a steam passage 32a and the upper and lower flows inside the fixed iron core 32 by the electromotive force and elastic member 33 induced by the coil 31 It consists of the planar 34 which opens and closes an entrance.

That is, in the steam discharge device of the rice cooker to the steam pressure of the cooking chamber so that the solenoid (30) to control the steam discharge, the solenoid (30) in the bottom of the fixed iron core 32, the electromotive force of the coil 31 is applied to the flanza (34) Forming a rocking region and elastically combined with the elastic member 33 with respect to the flanza 34, but the vapor passage 32a and 34a to the fixed iron core 32 and the planar 34 It was formed and assembled in communication, the lower end of the fixed iron core 32 is assembled in the inner lid 21 and is located in the connector (35) formed with the through hole (35a), the connector 35 is exposed to the cooking chamber Assembled by the fastening member 36 formed with a through hole (36a) so that the tip sealing member 38 of the planar 34 to match the through hole (35a) of the connector 35, the upper end of the fixed iron core 32 The steam passage 32a coincides with the through hole 37a by fastening and assembling with the outer lid 22 by the binding member 37 having the through hole 37a formed therein. It is assembled to be configured.

In the conventional steam discharge device of the electric thermal pressure cooker, the configuration according to the present invention, the edge is fixed between the blocking member 40 and the connector 35 of the coil cover 39 as shown in FIG. The packing member 51 is disposed so that the center thereof is fixed by the planar 34 so that the steam induced into the steam inflow space S does not come into contact with the blocking member 40 by the packing member 51, and the coil It is a structure which can suppress that it enters into the space between 31 and the fixed iron core 32 and the planar 34, etc.

Here, the lower end of the steam passage 34a formed in the flanza 34 has an X-shape. Reference numeral 52 is a packing member.

The present invention configured as described above, the elastic member in the state that the power is disconnected to the solenoid (30) according to the command by the program set according to the menu to be cooked for a predetermined cooking object in the state in which the present invention is applied to the electric thermal pressure cooker ( The sealing member 38 fixed to the lower end of the planar 34 by the restoring force of 33 is to maintain the closed state in the through hole 35a of the connector 35 as shown in FIG.

As described above, in the state in which the sealing member 38 of the flanza 34 closes the through hole 35a by the restoring force of the elastic member 33, the cooking chamber pressure of the inner container 11 rises above the safety pressure. When the high vapor pressure is applied to the sealing member 38 closing the through hole 35a of the connector 35 through the through hole 36a of the fastening member 36 exposed to the cooking chamber, the planar 34 Pressurizes the elastic member 33 disposed on the steam passages 32a and 34a to open the through hole 35a so that the steam pressure of the cooking chamber is increased through the through hole 36a and the connector 35 of the fastening member 36. It is discharged to the outside through the through hole 37a of the binding member 37 via the vapor passage 34a of the planar 34 and the vapor passage 32a of the fixed iron core 32.
