Description

Poise valve of electrical pressure rice oven

The present invention relates to a poise valve of an electric pressure cooker, and more particularly, a packing member connected to a spring-wound moving member having its own elastic force retreats forward to a gear part driven by a motor, and the steam discharge pressure is increased in multiple stages. The poise valve of the electric pressure cooker is adjustable.

In general, the electric pressure cooker to cook food, such as grains stored therein using electricity as a heating source, the inside of the pressure cooker is cooking is heated while maintaining a high pressure state.

As described above, in the electric pressure cooker in which cooking is performed, as illustrated in FIG. 1, the oven 10 storing the cooking objects opens and closes the opening portion of the main body 12 and the main body 12 with the lower hot plate therebetween. It consists largely of a lid 14 to which an upper hot plate is attached.

And, the electric pressure cooker is configured to include an electric device for heating / keeping the oven and a pressure regulator for controlling the pressure in the oven during cooking.

At this time, the electric device is composed of a working coil (Working coil: 16) that is mounted to the main body to generate an induction current when cooking and a heater (Heater: 18) for performing a relatively weak heat generating action when warming.

The pressure regulating device is a solenoid valve (20) that lowers the pressure in the oven by automatically opening after a predetermined time elapses from the start of cooking and when the pressure in the oven exceeds a predetermined value, it is opened by opening in the oven. Poise valve (30) to prevent the pressure rise excessively and to be kept constant.

Such a pressure regulating device poise valve of an electric pressure cooker is published in Korean Patent Publication No. 96792 in 2001.

According to the 2001 Korean Patent Publication No. 96792, a steam discharge pipe 32 penetrated through a lid having a steam discharge path 32 a therein and an insertion hole into which a tip of the steam discharge pipe 32 is inserted is inserted. (34a) is provided with a valve pin 35 for opening and closing the upper end, the pressure weight 34 and the steam exhaust pipe 32 and the pressure addition that is detachably bound to the steam exhaust pipe 32 by a simple fitting method Disclosed is to include a binding means for binding.

At this time, the binding means is attached to the upper periphery of the vapor discharge pipe 32 is made of an elastic material engaging ring 40 having a volume slightly larger than the insertion hole (34a) of the pressure weight (34).

However, development of various types of poise valves is required separately from the poise valves of the conventional electric pressure cooker.

The object of the present invention is to move forward and backward by the drive of the motor

The packing member is configured to open and close the steam discharge passage to provide a poise valve of the electric pressure cooker to control the pressure control in multiple stages.

Poise valve of the electric pressure cooker according to the present invention for achieving the above object, in the poise valve of the electric pressure cooker which is opened and closed to prevent excessively increased pressure in the oven, the steam inlet is formed on the bottom surface side A lower body in which steam outlets are formed; A packing member in contact with the steam inlet and fixed to the lower body to open and close the steam inlet; A moving member fixed to the packing member and wound on a spring; A first gear part which is fastened to the outside of the moving member to support the spring while moving forward and backward; A second gear unit rotating to move the first gear unit forward and backward; And a motor for rotating the second gear part.

Here, the first gear portion is usually made, the second gear portion is formed in a columnar shape accommodated in the first gear portion and is fastened to each other on the inner surface of the first gear portion and the outer surface of the second gear portion, Preferably, screw grooves for converting the rotational motion of the second gear part into the linear motion of the first gear part are formed.

In addition, a through hole may be formed at an end of the first gear part to allow the moving member to move therethrough, and the motor may be a stepping motor.

In addition, the spring may be supported at both ends by a stepped portion formed on the outer circumferential surface of the movable member and a spring insertion groove formed in the first gear portion.

In addition, the steam outlet and the steam discharge passage may be connected.

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

The poise valve of the electric pressure cooker according to the present invention, as shown in Figure 2 and 3, the lower body is inserted into the insertion hole (40a) of the upper hot plate 40 is fastened to the opening of the oven of the electric pressure cooker ( 46).

In this case, a steam inlet 42 through which steam generated in the oven is introduced is formed at the bottom of the lower body 46, and steam passing through the steam inlet 42 is provided at a side of the lower body 46. Vapor discharge ports 44a and 44b are formed to guide the discharge ports 70a and 70b.

In addition, the lower body 46 is provided with a packing member 48 which directly opens and closes the steam inlet 42 by being stretched and contracted by an external physical force and being contacted or spaced apart from the steam inlet 42 by being stretched and contracted by an external physical force. It is.

In addition, a fixing member connected to the packing member 48 and provided with a moving member 50 wound with an elastic spring 56 on the outside, and installed on the outside of the moving member 56, the spring 56 is elastic The first gear part 58 which supports is comprised.

At this time, the first gear portion 58 is formed in a cylindrical shape formed with a screw groove 60 for converting the rotational motion applied to the inside into a straight motion, the center portion of the moving member 50 is penetrated. The through hole 61 is formed to be possible.

In addition, a screw groove 62a formed in a columnar shape inside the first gear part 58 and capable of forwarding and reversing the first gear part 58 by being self-rotating with each other by being engaged with the first gear part 58. The formed second gear part 62 is provided.

In addition, a motor 64 such as a stepping motor, which is connected to the second gear part 62 to rotate the second gear part 62, is provided separately.

The spring 56 is fixed to a spring insertion groove 52 formed around the through hole 61 of the first gear part 58 and a moving member 50 on the side connected to the packing member 48. By the jaw portion (54).

Therefore, when the motor 64 is driven under the control of the microcomputer for food cooking, as shown in FIG. 2, the second gear part 62 rotates as the second gear part 62 is driven by the driving of the motor 64. The first gear portion 58 engaged with 62 is advanced.

The first gear portion 58 contracts the spring 56 wound on the outside of the movable member 50, and the second gear portion 62 after the predetermined distance moves moves by pushing the movable member 50 forward. The packing member 48 connected to the member 50 blocks the steam inlet 42. At this time, the degree of compression of the spring 56 is adjusted to various states according to the degree of advancement of the first gear unit 58 so that the packing member 48 is separated in response to various pressure conditions.

Next, when the cooking of the food is made in this state and the steam generated in the cooking process of the food is more than a predetermined pressure at the steam inlet 42, the packing member 48 is pushed and the steam outlets 44a and 44b. It is discharged to the outside through the diesel steam discharge passage (70a, 70b).

At this time, as the packing member 48 moves backward by the vapor pressure, the spring 56 wound on the outside of the moving member 50 is further contracted.

According to the present invention, in order to prevent the pressure in the oven from being excessively raised, the gear part is moved forward and backward by the driving of the motor to open and close the steam inlet by the packing member to block the steam, so that the discharge pressure condition can be multistage. It's effective.

Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention. will be.
