[0009] The present invention is implemented in several ways, including different heating materials, different heat storage materials, and different shells, to achieve the same goal: to manufacture a heat storage heating device that is simple, energy-saving, and convenient for the people. The following will explain them separately.

[0010] The shell is provided with a heat storage body, which is composed of a left heat storage body and a right heat storage body, and an electric heating tube is provided between the left heat storage body and the right heat storage body. This design has two functions: first, the surface temperature of the electric heating tube is above 200°C, and such a high temperature will burn people. The left heat storage body and the right heat storage body are used to block the high temperature in the shell, and absorb and store part of the heat to keep the surface temperature of the shell within a safe range. Although the temperature controller has the function of power off at ultra-high temperature, it is only used as a precaution. The design of the heat storage body solves the problem of ultra-high temperature from a structural perspective; second, after the heat storage body absorbs heat, part of the heat is stored in the left heat storage body and the right heat storage body, which can keep the temperature in the shell for a certain heat dissipation time after the power outage. The upper part of the shell is provided with a heat dissipation hole and the lower part is provided with an air inlet hole, so that the temperature in the shell can be smoothly dissipated through air convection. A temperature sensing probe is provided in the shell, and the temperature sensing probe is set at a position where the heat storage body does not contact the electric heating tube. The heat storage body is an outer packaging aluminum foil bag, which can also be made of stainless steel sheets or galvanized sheets. The aluminum foil bag is formed into several small grids by the heat storage body dividing line. The heat storage material A contained in the aluminum foil bag includes one or more heat storage materials selected from expanded vermiculite, zeolite, perlite, rock salt, expanded graphite, and volcanic stone. The above-mentioned sensible heat storage material relies on the temperature change of the heat storage material to store heat. The heat cannot be stored for a long time and is not suitable for long-term large-capacity heat storage. Therefore, it is impossible to store heat for ten hours during valley power at night and dissipate heat for ten hours during peak power during the day. It can only store heat and dissipate heat quickly for a short period of time, such as storing heat for one hour and dissipating heat for one hour, and repeating the cycle. Because of this, the purpose of small size, light weight, low cost, and 50% energy saving is achieved.

[0011] Finally, the temperature sensing probe is connected to the temperature controller, the heating tube power cord is connected to the temperature controller, the power cord is connected to the temperature controller, the power cord is connected to the power plug, the power plug is inserted into the time control switch, and the time control switch is connected to the time control switch power supply.

[0012] The upper connecting pipe and the lower connecting pipe are connected and interpenetrated by a vertical pipe, and the upper connecting pipe, the vertical pipe and the lower connecting pipe are welded into one, which is the existing superconducting radiator structure. This superconducting heater can be bought on the market. After actual testing, the purchased superconducting heater finished product can only maintain the heat dissipation time of about 20 minutes after power failure due to the small volume of the lower connecting pipe, the small amount of heat storage material loaded, and the insufficient heat storage. It needs to be modified. The original lower connecting pipe should be cut open, and a lower connecting pipe twice as large as the original pipe should be re-welded, and enough heat storage material should be loaded to achieve power failure heat dissipation for 1 hour. The experimental results after improvement have reached the design requirements of heating for one hour while heating, and then stopping the power to continue heating for one hour, and repeatedly circulating the heating.

[0013] The heat storage material A is placed in the lower connecting tube, the superconducting liquid is placed, and the electric heating tube is installed. The heat generated by the electric heating tube causes the superconducting liquid to heat up and vaporize. The hot gas reaches the upper connecting tube through the vertical tube, and part of the heat is stored in the heat storage material A. The installation sequence is: the power line terminal of the electric heating tube extends out of the lower tube left-spinning cover through the electric heating tube socket of the lower tube left-spinning cover, the electric heating tube and the lower tube left-spinning cover are glued into one, the electric heating tube integrated with the lower tube left-spinning cover is placed into the lower connecting tube from the left port of the lower connecting tube, the lower tube left-spinning cover is threadedly connected to the lower connecting tube, tightened and sealed, and one or more materials selected from expanded vermiculite, zeolite, perlite, rock salt, expanded graphite, and volcanic stone are placed from the right port of the lower connecting tube; the superconducting liquid is injected from the right port of the lower connecting tube, the lower tube right-spinning cover is threadedly connected to the lower connecting tube, tightened and sealed; the upper tube exhaust valve is installed at the right end of the upper connecting tube, and the threaded connection is tightened and sealed. Its function is to open the exhaust valve of the upper tube after the electric heating tube is powered on for a certain period of time, and use the pressure left by the superconducting liquid to discharge the cold air in the original tube, otherwise the upper connecting tube will not be hot. In this way, the small amount of heat storage and release cycle is carried out every hour, and the heat storage material can be used to solve the complementarity of heat energy in time and space, achieving the energy saving purpose of effective multiplication of energy.

[0014] Finally, the temperature sensing probe is connected to the temperature controller, the heating tube power cord is connected to the temperature controller, the power cord is connected to the temperature controller, the power cord is connected to the power plug, the power plug is inserted into the time control switch, and the time control switch is connected to the time control switch power supply.

The left plug and the right plug for the floor heating pipe are provided with threading holes and female-sub terminal fixing grooves. One end of the positive pole of the electric heating wire passes through the threading hole of the left plug for the floor heating pipe and is connected with the convex terminal. The electric heating wire is put into the heat storage floor heating pipe, and then the left plug for the floor heating pipe is inserted into the left end of the floor heating pipe and sealed with glue. The electric heating wire is straightened from the right end of the heat storage floor heating pipe, and heat storage material B is injected. The heat storage material B squeezes the electric heating wire firmly, and the negative pole of the electric heating wire passes through the threading hole and is connected with the concave terminal. The right plug for the floor heating pipe is inserted into the right end of the floor heating pipe and is sealed with glue.

[0016] The heat storage floor heating pipe is equipped with heat storage material B, which is a heat storage ball, also known as a spherical heat storage body, with a particle size of 1-2 mm, and the material is composite magnesium oxide. Compared with heat storage material A, it has the advantages of large heat storage and heat release and good thermal conductivity. Heat storage material B is wrapped around the electric heating wire in the floor heating pipe, and part of the heat generated by the electric heating wire is stored in heat storage material B.

[0017] The concave connection terminal of the heat storage floor heating pipe is fixed with the convex connection terminal, and several floor heating pipes are connected as a whole by the concave and convex connection points. The positive power line is connected to the positive poles of several power supplies, and the negative power line is connected to the negative poles of several power supplies. The positive pole of the power line is arranged at one end of the floor heating pipe and connected to the convex connection point, and the negative pole of the power line is arranged at the other end of the floor heating pipe and connected to the concave connection point; the convex connection point and the concave connection point are respectively inserted into the concave and convex fixing positions for fixing, and several heat storage floor heating pipes are connected through the convex and concave power supply. After the connection, the negative poles of the power lines of several heat storage floor heating pipes are connected together by the negative power line, and the positive poles of the power lines of several heat storage floor heating pipes are connected together by the positive power line. This is the structure for laying several heat storage floor heating pipes in the room. The total number of heat storage floor heating pipes is determined according to the area of ​​the room, and then the number of floor heating pipes required for each row is determined, and the distance between the rows of floor heating pipes is determined. The floor heating pipes are connected and laid according to the above data. Each row of several heat storage floor heating pipes is connected through the convex and concave power supply, so that a row of several heat storage floor heating pipes becomes one, with only one positive pole and one negative pole. After laying multiple rows of several heat storage floor heating pipes according to the determined distance between rows, connect the positive poles of the power lines of each row with the positive power lines, and connect the negative poles of the power lines of each row with the negative power lines. Finally, the temperature sensing probe is connected to the temperature controller, the positive power line and the negative power line are connected to the temperature controller, the power line is connected to the temperature controller, the power line is connected to the power plug, the power plug is inserted into the time control switch, and the time control switch is connected to the time control switch power supply. The heat storage floor heating is powered on for one hour to provide heating while storing heat, and then the power is turned off and the heating is continued for one hour, and the energy-saving purpose of repeated heating cycles is achieved.
