Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hot water boiler for improving the circulation flow of natural water by a piston pump,

A piston pump is formed between a water tank and a heater to circulate (supply) water in a circulating hose toward a hot water mat. A check valve for promoting one-way flow of water is formed on the line to the circulating hose pipe which is the inlet-side front end portion and the water-outlet-side rear end portion of the piston pump, thereby achieving a smooth circulation cycle, while the piston pump is pumped (2) can be operated through one driving unit motor, so that it is possible to realize an inexpensive manufacturing cost when manufacturing a separate heating mat including the original heating, which can reduce the number of motors applied to the former impeller type circulation pump by 1/2 It is possible to reduce the initial manufacturing cost as well as the AS cost such as replacement after the exchange and the maintenance cost By the piston pump, it characterized in that the property is significantly improved relates to a hot water boiler of the hot water mat improve the natural circulation of water flow.

Generally, a hot water mat refers to heating water stored in a water tank with an electric heater of a hot water boiler circulating device to supply hot water generated by the water heater to a supply hose provided inside the hot water mat and circulating the water.

Accordingly, there is an advantage that the hot water mat can solve the problems of existing electric mats in which the electric heating element is built up, that is, the risk of fire or electric shock due to harmful electromagnetic waves and electric hot wire.

Meanwhile, a forced circulation type hot water boiler using an electric motor pump or the like is generally used according to a system in which hot water heated by an electric heating element is circulated in a conventional hot water boiler circulating apparatus for a hot water mat. In recent years, (Non-motorized) hot water boiler circulation system.

Accordingly, the natural circulation hot water boiler circulation apparatus includes a check valve body, a heater unit, and a power supply unit (PCB).

The water storage tank stores hot water circulated to the inside of the hot water mat and hot water to be recovered. The check valve body supplies water to the heater unit and prevents the water from flowing back in the course of heating the supplied water.

In addition, the heater unit heats the water and vaporizes some water to create the expansion pressure which is the driving force of the hot water circulation, and the power supply unit (PCB) controls the electric parts including the heater power supply, temperature, water level and pressure.

The natural circulation hot water boiler circulation device prevents the hot water heated by the blocking plate located inside the check valve body from flowing back to the water tank by the expansion pressure generated in the process of heating the water by the electric heater, The hot water is discharged to the hot water mat, and the hot water passing through the hot water mat is circulated in a manner that the temperature is lowered to the low temperature water and discharged to the water tank, and then supplied to the electric heater through the check valve body in the water tank.

In other words, this natural circulation (non-motorized) hot water boiler has a main technical point that it does not require an electric motor pump to heat and circulate hot water.

However, the natural circulation type hot water boiler which is actually being marketed is circulating the water by the pressure difference caused by the heating temperature, so that the flow of the water, that is, the flow rate is too slow, The problem is continuing.
