BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a steam condensing apparatus that can easily separate a cooling water tank, and more particularly, to a steam condensing apparatus that facilitates separation of a cooling water tank for condensing steam generated in an electric pressure cooker.

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 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 .

In this prior art, the cup lid is coupled to the upper end of the receiving cup, and the steam passing line passing through the guide hole of the cup lid is coupled to the upper portion of the shutoff plate so that the steam passes through the steam passing line, the communication portion, And then discharged into the cooling water inside the receiving cup.

In this case, in order to disassemble each of the components for cleaning the receiving cup and the pressure-sensitive member, there is a problem that the separating operation is troublesome because the separating operation is required since the separating plate is separated from the receiving cup by rotating the cup lid.

In addition, when the pressure of the steam discharged from the solenoid valve is excessive, the pressure of the inside of the receiving cup can be maintained at an appropriate pressure while the blocking plate is lifted by a predetermined distance. However, the steam pipe and the pressure- And the steam pipe is configured to penetrate the guide hole. However, since the steam pipe is not guided around the guide hole, the blocking plate is difficult to smoothly float, and it is difficult to maintain the pressure of the steam at an appropriate pressure .

Further, even if the steam is discharged to the outside due to the floating of the shutoff plate, the path through which the steam is discharged is short, and the pressure reducing hole is formed in the pressure reducing member so that the steam is discharged to the inner space of the receiving cup through the pressure- There is a problem that the amount of unheated steam increases.
