Description

[0001] The present invention relates to a steam condensing apparatus of an electric pressure cooker,

The present invention relates to a steam condenser for an electric pressure cooker, and more particularly, to a steam condenser for an electric pressure cooker, more particularly, to a steam condenser for condensing steam generated in an electric pressure cooker in a cooling water tank, thereby minimizing noise generated during steam discharge, To a steam condenser of an electric pressure cooker capable of preventing a safety accident of a consumer.

The electric pressure cooker is a device that cooks food by making the inside of the inner pot heated to a high temperature and high pressure by containing the food to be cooked in the inner pot.

A general electric pressure cooker is composed of an inner pot that houses foods to be cooked, a main body that houses the inner pot, a main lid that covers the main body, and an inner lid that is coupled to the bottom of the main lid to cover the inner pot.

Also, as the cooking progresses, the inside of the inner pot becomes a high temperature and high pressure state due to the steam. Therefore, a steam discharging device for discharging the steam to the outside is provided for controlling the pressure inside the inner pot.

The steam discharging device includes a solenoid valve operated according to an electrical signal to discharge steam in the inner pot, and a weight attached to the end of the steam discharging valve to open and close the steam discharging valve.

The weight of the inner pot is maintained at a constant pressure while the weight of the inner pot is being cooked while the solenoid valve discharges residual pressure inside the inner pot during or after cooking.

In the conventional electric pressure cooker, when the steam of high temperature and high pressure is discharged from the solenoid valve and the weight, the user may be injured due to carelessness, and the steam is directly discharged into the atmosphere to generate noise, May come in contact with wallpaper and kitchen utensils, resulting in discoloration and mold.

In order to solve such a problem, Korean Utility Model No. 443109 discloses a technique for conveying steam discharged through a solenoid valve (solenoid valve) of an electric pressure cooker to a receiving cup containing a cooling water through a steam feeding pipe to condense it .

However, in this conventional technique, the steam discharged from the steam outlet (electromagnetic valve) is directly introduced into the steam pipe having a narrow cross-sectional area, so that a large noise is generated when the steam is discharged, and only the steam discharged from the electromagnetic valve is transferred to the receiving cup, And the steam discharged through the weight is directly discharged into the atmosphere.

In addition, since the steam discharged from the solenoid valve is transferred through one steam pipe, pressure fluctuation occurs in the inside of the receiving cup or pressure fluctuation occurs when the steam is discharged from the steam outlet, so that the steam discharged from the steam outlet flows back to the solenoid valve The solenoid valve malfunctions.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to minimize the noise generated when steam is discharged, prevent the steam from flowing back to the solenoid valve, It is an object of the present invention to provide a steam condenser of an electric pressure cooker which is easy to operate.

According to an aspect of the present invention, there is provided an apparatus for vapor condensation of an electric pressure cooker, including: a vapor discharge valve provided in a main body lid of an electric pressure cooker; and a steam flowing from a solenoid valve A steam cap including an upper cap and a lower cap so that a flow path is formed inside; And a cooling water tank for condensing the steam transferred through the steam passage using cooling water, wherein the upper cap and the lower cap are detachably coupled to each other

The lower cap may be installed in a steam cap mounting groove formed to be recessed on an upper surface of the main body cap so that the steam discharge valve and the solenoid valve penetrate the bottom surface.

The upper cap and the lower cap may be such that side threads are engaged with each other by rotation.

A plurality of upper cap protrusions may be formed on an outer surface of the upper cap.

Wherein the steam passage in the steam cap comprises a first steam passage through which the steam discharged from the steam discharge valve flows and a second steam passage through which the steam discharged from the solenoid valve flows, The steam passages may be isolated from each other.

The upper coupling part formed on the side body of the upper cap and the lower coupling part formed on the side body of the lower cap may be coupled by the engagement.

According to the steam condensing apparatus of the electric pressure cooker of the present invention, since the steam discharged from the inner pot flows through the steam passage inside the steam cap sealed to the outside and then condensed in the cooling water tank, noise generation can be minimized, It is possible to prevent a safety accident.

Also, the steam cap is composed of a top cap and a bottom cap formed with threads, so that separation and coupling work of the top cap and the bottom cap can be facilitated by rotation.

Further, the steam cap is seated in the steam cap mounting groove formed in the main body cover, and the guide protrusion is inserted into the steam cap mounting guide, thereby preventing the steam cap from flowing.

In addition, the steam cap is formed inside the steam cap so that the steam discharged from the steam discharge valve and the solenoid valve can flow independently of each other, so that the steam and the cooling water can be prevented from flowing back to the solenoid valve side.
