Description

Hot water bolier of hot water mat with Piston pump and check valva improves natural circulation of water by piston pump

The present invention is to improve the water flow (improved water circulation rate-improved performance) of the natural circulation non-powered hot water boiler, the piston pump is formed between the bucket and the heater to circulate the water in the circulation hose toward the hot water mat (supply) The speed is remarkably improved, but a check valve for unidirectional flow of water is built into the water tank to facilitate a smooth circulation cycle, while the piston pump has a plurality of pumping parts operated by one driving motor. It is formed so that the manufacturing cost can be realized at the time of manufacturing a separate heating mat including raw heating, which can reduce the amount of applied motor by 1/2 compared to the conventional impeller type circulation pump, thus saving initial manufacturing cost and exchanging afterwards. The piston pump is characterized by a significant improvement in AS cost and maintenance workability such as replacement. It relates to a hot water boiler for hot water mat to improve the circulation of water flow.

In general, the hot water mat refers to circulating the hot water generated by heating the water stored in the water tank with the electric heater of the hot water boiler circulation device to the supply hose installed inside the hot water mat.

Therefore, the hot water mat has the advantage that it is possible to solve the problems of the existing electric mat configured to embed the electric heating element, that is, the risk of fire or electric shock by harmful electromagnetic waves and electric heating wire.

On the other hand, the conventional hot water boiler circulator for hot water mat is generally used a forced circulation hot water boiler using an electric motor pump or the like according to the method of circulating the hot water heated by the electric heating element, recently circulating the hot water by the expansion pressure It is divided into natural circulation type (non-powered) hot water boiler circulation system.

Thus, the natural circulation hot water boiler circulation device is composed of a check valve body, a heater unit, and a power supply (PCB).

The reservoir stores hot water circulated into the hot water mat and hot water recovered, and the check valve body supplies water to the heater and prevents backflow in the process of heating the supplied water.

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

The natural circulation hot water boiler circulator prevents the hot water heated by the blocking plate located inside the check valve body from flowing back into the reservoir by the expansion pressure generated in the process of heating the water with the electric heater, and expands the expansion pressure more than a predetermined value. When the hot water is discharged to the hot water mat, the hot water passing through the hot water mat is lowered to low temperature water and discharged to the reservoir, and then circulated by supplying it back to the electric heater through the check valve body in the reservoir.

In other words, such natural circulation (non-powered) hot water boilers have the main technical gist that they do not require an electric motor pump to heat and circulate the hot water.

However, the natural circulation hot water boilers on the market circulate water with the pressure difference due to the heating temperature, so that the flow of water, i.e., the flow rate is too slow, takes considerable time to circulate one cycle around the hot water mat, resulting in poor product performance. The problem continues.
