Description

Drainage trap for steam boiler in laundry {WATER DISCHARGING TRAP FOR A STEAM BOILER USING A LAUNDRY}

The present invention relates to a drain trap for a steam boiler used in a laundry, and more particularly, for a steam boiler of a laundry that allows the inflow of steam to be quickly recirculated while preventing the malfunction of water level detection by splashing water. It is about the drainage trap.

In general, in a laundry, it is finished by ironing to unfold the creases of the cloths that generate creases during the washing and washing process. A steam-injection iron is used to spread the creases of the fabric more easily.The iron allows steam to be sprayed onto the fabric from time to time in the process of legging the fabric.In order to perform steam ironing, steam including an iron is used. The generation system must be provided in the laundry.

As shown in Figure 4, the laundry has a water tank (T) connected to the water supply (W), a steam boiler (B) connected to the water tank (T), and a steam boiler (B) connected to the steam boiler (B). There is provided a steam supply system comprising an iron (D) that is supplied with and a discharge pipe (P) through which steam and water remaining after being used in the iron (D) are discharged from the iron (D) to the outside.

The water supplied to the water tank (T) through the water (W) is heated after flowing into the boiler (B) from the water tank (T), and accordingly, steam is generated from the steam boiler (B). The generated steam is continuously supplied from the steam boiler (B) to the iron (D).

The steam supplied to the iron (D) remains after being used, and the remaining steam is discharged together with water generated by condensation to a water collecting container (C) into which a discharge pipe (P) is inserted, and the water collecting container The water discharged to (C) is discarded after being collected in the water collecting container (C), and the vapor is dispersed to the outside air with discharge.

However, during the operation of the steam boiler of the laundry, the remaining steam or unused steam that has been used after being supplied to the iron is continuously discharged to the outside through the discharge pipe, so that the steam continues without blocking during the operation of the steam boiler, whether the iron is used or not. As it is discharged to the outside through the discharge pipe, there is a problem that causes enormous energy loss.

To solve this problem, a drain trap with a water level detector is installed at the end of the discharge pipe to properly block the steam continuously discharged to the outside during operation of the steam boiler in the laundry, while intermittently draining the water and discharging the steam. A technique for remarkably reducing energy loss has been proposed.

However, the prior art as described above has the following problems.

In conventional drain traps for steam boilers, water is rapidly introduced into the drain trap by high-pressure steam along with steam, and water splashes from the inside of the drain trap and touches the water level detector, causing a malfunction of the water level detection, resulting in significantly low operational stability. There was a problem.

In addition, the conventional drain trap has a structure that does not rapidly recirculate the steam introduced therein, so that steam is discharged together with water, causing frequent energy loss.

In addition, there is a problem in that the life of the conventional drain trap is shortened, such as failure of a valve or the like due to foreign matter such as rust stacked inside the pipe and the drain trap as it is used for a long time.
