Boiler for electric hot water mat with hot water circulation prevention function

摘要

The present invention relates to a boiler device for an electric hot water mat having a function of preventing reverse circulation of hot water, and more particularly, to prevent the discharged hot water from flowing back to the electric heater while discharging hot water heated by the electric heater of the boiler device. It is invented to improve product satisfaction by preventing product failure. The configuration of the present invention is a water tank 10 having an accommodation space for storing hot water and having an outlet 11 and a recovery port 12 for discharging and recovering the hot water on one side, and an outlet of the water tank 10 Hot water by connecting the electric heater 20 connected to (11) to heat hot water to supply it to the supply pipe 41 of the heating pipe, and the recovery port 12 of the water tank 10 and the drain pipe 42 of the heating pipe. One side is assembled to the inlet pipe 30 for recovering the water to the water tank 10, the electric heater 20 and the inlet pipe 30, and the other side is attached to the supply pipe 41 and the drain pipe 42 of the heating pipe. In the boiler apparatus for an electric hot water mat configured including a connecting member 50 that is assembled and interconnected, respectively; In the connecting member 50, a plate fixing groove 52 and a pin insertion groove 53 are continuously formed in the hot water inlet 51 on one side to be assembled with the electric heater 20 to close the hot water inlet 51 or As the open backflow prevention plate 60 is inserted into the hot water inlet 51, a rotation pin 61 integrally formed on the top is assembled in the pin insertion groove 53 and is rotatably installed, and the plate fixing groove 52 The finishing cover (70) is inserted in the backflow prevention plate (60) to prevent reverse rotation in the direction of the electric heater (20), and the hot water supplied to the supply pipe (41) of the heating pipe is heated by the electric heater (20). It is configured to prevent reverse flow in the (20) direction to achieve.
