Hot water circulation apparatus

The present invention relates to a hot water circulation system that can continuously supply hot water to the place of use such as a mat, hot pad, etc. without using a motor pump circulating the hot water, and to increase the temperature of the hot water lowered at the place of use to circulate it to the place of use. In more detail, the water supplied to the heating tank is pumped and circulated stably by using hot water supplied from the heating tank to the pumping tank using steam pressure generated during high temperature heating so that efficient heating is achieved.

Republic of Korea Patent No.526791 (registered October 31, 2005) is introduced "hot water automatic circulation device".
The hot water automatic circulation device is provided with a supply port and an outlet at the top and bottom, respectively, the boiler for supplying cold water to the supply port and discharge hot water to the discharge port; An electric heater installed horizontally while being in contact with a bottom surface of the inner bottom of the boiler and supplying heat to the inside of the boiler; A water tank connected to a supply port of the boiler and a supply pipe to supply cold water to the boiler; An inlet connected to the outlet and the discharge pipe of the boiler, and a heat exchanger connected to the outlet of the water tank and the circulation pipe to transfer heat to the outside; Each of the supply pipe and the discharge pipe is provided with a supply valve and a discharge valve that is automatically opened and closed by the steam pressure inside the boiler.
However, since the supply valve and the discharge valve are opened and closed by steam pressure, the hot water automatic circulation device has a large operating error of the supply valve and the discharge valve, and it is difficult to control the use temperature of a mat or a hot pad.
To this end, the applicant has been registered in the Republic of Korea patent application No. 10-872414 (name: hot water circulation device).
The hot water circulation device is equipped with a heating device 20 in the heating tank 10 to heat the water 12 filled in the heating tank 10, the heating tank 10 and the pumping tank 30 A first valve V1 is mounted to the first water pipe 40 to be connected, and the pumping tank 30 is divided into a first chamber 32 and a second chamber 33 by a diaphragm 31. The injection hole of the balloon 35 is mounted in the piping part 34 formed at the center of the diaphragm 31, so that the balloon 35 is disposed in the second chamber 33, and above the heating tank 10. A recovery tank 50 is disposed, and the recovery tank 50 and the heating tank 10 are connected by a second water pipe 60, and a second valve V2 is connected to the second water pipe 60. Is mounted, the hot water line 80 connected to the discharge port 37 of the pumping tank 30 is connected to the recovery tank 50 through the mat 85, the hot water 12 of the heating tank 10 is the pumping tank (30), the mat (85), and the recovery tank 50 in order to heat again Circulated to the tank 10, the heating device 20 is configured to control the operation by the controller (90).
In the above configuration, hot water of the heating tank 10 is supplied to the pumping tank 30 through the first water pipe 40 at a predetermined pressure by the internal pressure of the heating tank 10, and the pumping tank ( Some of the hot water supplied to the 30 is supplied to the mat 85 through the discharge port 37 of the pumping tank 30, the rest is supplied to the balloon 35, the balloon 35 is inflated.
The hot water passing through the hot water line 80 supplies heat to the mat 85 so that the temperature of the mat is increased, and the water passing through the mat 85 is circulated to the heating tank 10 through the recovery tank 50. .
In this way, the water is circulated from the heating tank to the heating tank again through the pumping tank, the mat, and the recovery tank, so that the level of the heating tank is kept substantially constant and stored in the heating tank 10 by the heating device 10. The temperature of the water to be maintained is maintained at the set temperature (for example, 80 ℃).
At this time, the balloon 35 of the pumping tank 30 reaches the maximum inflated state, and the expansion of the balloon is limited according to the size of the second chamber 33 of the pumping tank 30. When the balloon 35 reaches the maximum inflated state, the amount of water supplied from the heating tank 10 to the pumping tank 30 is equal to the amount of water discharged from the pumping tank 30 through the discharge port 37. .
Then, in the steady state, when the temperature of the mat 85 reaches the set temperature (eg, 40 ° C.), the operation of the heating device 20 is stopped by the controller 90. Then, when the temperature of the water of the heating tank 10 reaches the lower limit set value (for example, 70 ℃), the first valve (V1) is closed, the heating device 20 is operated to the water of the heating tank 10 Heat it. At this time, as the balloon 35 that has been inflated is contracted, hot water is continuously supplied to the mat 85. Thereafter, when the hot water temperature of the heating tank 10 reaches the set temperature, the first valve V1 is opened to supply the hot water to the mat.
However, the balloon 35 in the pumping tank 30 receives and expands hot water heated from a heating tank, and the repetitive action of contracting acts according to the elasticity of the balloon material. Will be less. These disadvantages also vary in the amount of hot water received, the pumping force of the hot water supplied to the mat side is a problem that causes adverse effects on the hot water circulation, even if the balloon is torn.

The present invention has been made to solve the conventional problems as described above, by using the steam pressure generated when the water supplied to the heating tank at high temperature heating pumped stably using the hot water supplied from the heating tank to the pumping tank. Its purpose is to circulate the energy to circulate efficiently.

According to the present invention for achieving the above object, a heating tank having a heating device for heating water and a temperature sensor for controlling the driving of the heating device, and a heating tank provided therein, the first water pipe and the first 1, a recovery tank for supplying water as a control valve and recovering and storing water from a heating mat through a hot water line, and a heating mat provided with a second water supply pipe and a heated water installed as a second control pipe and a second control valve. In the hot water circulation system comprising a pumping tank for pumping to the side, and a controller connected to the heating device of the heating tank,
The pumping tank is provided with a partition wall having a hot water supply hole formed therein, and provided with a first chamber and a second chamber to receive hot water heated from a heating tank, and the second chamber is made of a material having heat resistance and no self-stretching property. The pressurized sac is guided and the cover is fixed to one side of the second chamber in which the pressurized sac is installed. On the cover, steam pressure generated by heating water from the heating tank is applied to the pressurized sac. The steam supply line for supplying is further connected, and the hot water supplied in the second chamber and the first chamber as the contraction and expansion conditions of the pressurized bag with respect to the steam pressure is configured to be supplied to the heating mat side.
