Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

The vapor-liquid separation mechanism 2 is a vapor-water separator, and the power supply mechanism is composed of a solar cell panel and a power supply controller.
The floor heating system has two working modes of heating and cleaning.
In the heating mode, the controller controls the opening and closing of each end of the loop switching mechanism 5 to enable the steam generating mechanism 1, the steam-liquid separating mechanism 2, the heat supplying mechanism 3, the condensate return mechanism 4 and the steam generating mechanism 1 to sequentially form a heating loop, and a worker operates according to the following steps:
firstly, a worker sends a signal to the steam generating mechanism 1 through the controller, and the steam generating mechanism 1 generates steam and transmits the steam to the steam-liquid separating mechanism 2 after receiving the signal.
And step two, the controller sends a signal to the vapor-liquid separation mechanism 2, and the vapor-liquid separation mechanism 2 filters the vapor transmitted by the vapor generation mechanism 1, so that the water in the vapor is further condensed and recovered through the input end of the condensation liquid return mechanism 4.
And step three, the steam passing through the steam-liquid separation mechanism 2 enters the heat supply mechanism 3 to heat the room, and finally enters the input end of the condensed liquid return mechanism 4 through the heat supply mechanism 3.
And step four, the controller sends a signal to the condensed liquid returning mechanism 4, and the condensed liquid returning mechanism 4 condenses the steam entering the condensed liquid returning mechanism 4 after receiving the signal. When the pressure in the steam generating mechanism 1 is too high, part of steam can directly enter the condensation liquid returning mechanism 4 for condensation so as to reduce the volume and further reduce the pressure. The condensation liquid returning mechanism 4 further condenses the water separated by the vapor-liquid separating mechanism 2, and finally the condensed water is transmitted back to the inside of the vapor generating mechanism 1 from the output end together.
In the cleaning mode, the controller controls the opening and closing of each end of the loop switching mechanism 5 to disconnect the steam generating mechanism 1, the steam-liquid separating mechanism 2, the condensed liquid returning mechanism 4 and the loop switching mechanism 5 from the heat supply mechanism 3, so that the cleaning mechanism 6 and the heat supply mechanism 3 form an independent loop. Steam in the heat supply mechanism 3 is emptied in advance and then cleaned, and washing liquid is filtered, recycled and utilized after cleaning, so that the energy-saving and environment-friendly heating system effectively solves the problem of pollution and blockage of a heating loop, prolongs the service life of equipment and is low in maintenance cost.
As shown in fig. 2, the steam generating mechanism 1 includes a water storage tank 1a, a pressure control assembly 1b, a water replenishing assembly 1c, an electromagnetic heater 1d, a steam feeding assembly 1e and a water level switch; the water storage tank 1a is placed on the work end of sending vapour subassembly 1e, water storage tank 1a is the metal material, pressure control subassembly 1b one end is installed on water storage tank 1a, the pressure control subassembly 1b other end is connected with 4 inputs of condensation liquid return mechanism, moisturizing subassembly 1c is seted up on water storage tank 1a, send vapour subassembly 1e to install on the output of water storage tank 1a and be connected with vapour-liquid separation mechanism 2, water level switch work end sets up in water storage tank 1a, pressure control subassembly 1b, moisturizing subassembly 1c, electromagnetic heater 1d, send vapour subassembly 1e, water level switch all is connected with the controller electricity.
The water storage tank 1a is used to store water for steam generation. The water in the water storage tank 1a is vaporized into steam through the electromagnetic heater 1d, the pressure in the water storage tank 1a is increased, and the steam enters the input end of the steam-liquid separation mechanism 2 through the output end of the water storage tank 1a under the action of the pressure and the steam sending component 1 e. When the water level switch detects that the water level in the water storage tank 1a is too low, a signal is sent to the controller, the controller sends a signal to the water supplementing assembly 1c after receiving the signal, the water supplementing assembly 1c introduces an external water source to supplement water to the water storage tank 1a, and the dry burning phenomenon is prevented. When the pressure control assembly 1b detects that the internal pressure of the water storage tank 1a is too high, a signal is sent to the controller, after the controller receives the signal, on one hand, the controller can stop generating steam to prevent explosion by closing the electromagnetic heater 1d, on the other hand, the controller transmits redundant part of steam to the input end of the condensed liquid returning mechanism 4 through the pressure control assembly 1b to be condensed, so that the steam returns to the water storage tank 1a again after the volume is reduced, explosion is prevented by combining two methods, and the safety is greatly improved. The energy consumption can be greatly reduced by generating steam through the electromagnetic heater 1d, and the steam heating device is economical and environment-friendly.

The first pressure valve 1b2 and the second pressure valve 1b3 are electric butterfly valves. The pressure gauge 1b1 monitors the pressure inside the water storage tank 1a in real time and sends a signal to the controller. When the internal pressure of the water storage tank 1a exceeds a set value, the controller sends signals to the first pressure valve 1b2 and the second pressure valve 1b3, the first pressure valve 1b2 and the second pressure valve 1b3 are switched on, and part of steam in the water storage tank 1a enters the liquid condensation and return mechanism 4 through the first steam return pipe 1b4 to be directly condensed. When the pressure control module 1b finishes the pressure reduction operation of the water storage tank 1a, the first pressure valve 1b2 and the second pressure valve 1b3 are closed, so that the steam can be prevented from being retained in the first steam return pipe 1b4, and the rest part of the steam can be gradually condensed and finally returns to the water storage tank 1a or enters the input end of the condensed liquid return mechanism 4.

The working principle of the invention is as follows:
the vapor-liquid separation mechanism 2 is a vapor-water separator, and the power supply mechanism is composed of a solar cell panel and a power supply controller.
The floor heating system has two working modes of heating and cleaning.
In the heating mode, the controller controls the opening and closing of each end of the loop switching mechanism 5 to enable the steam generating mechanism 1, the steam-liquid separating mechanism 2, the heat supplying mechanism 3, the condensate return mechanism 4 and the steam generating mechanism 1 to sequentially form a heating loop, and a worker operates according to the following steps:
firstly, a worker sends a signal to the steam generating mechanism 1 through the controller, and the steam generating mechanism 1 generates steam and transmits the steam to the steam-liquid separating mechanism 2 after receiving the signal.
And step two, the controller sends a signal to the vapor-liquid separation mechanism 2, and the vapor-liquid separation mechanism 2 filters the vapor transmitted by the vapor generation mechanism 1, so that the water in the vapor is further condensed and recovered through the input end of the condensation liquid return mechanism 4.
And step three, the steam passing through the steam-liquid separation mechanism 2 enters the heat supply mechanism 3 to heat the room, and finally enters the input end of the condensed liquid return mechanism 4 through the heat supply mechanism 3.
And step four, the controller sends a signal to the condensed liquid returning mechanism 4, and the condensed liquid returning mechanism 4 condenses the steam entering the condensed liquid returning mechanism 4 after receiving the signal. When the pressure in the steam generating mechanism 1 is too high, part of steam can directly enter the condensation liquid returning mechanism 4 for condensation so as to reduce the volume and further reduce the pressure. The condensation liquid returning mechanism 4 further condenses the water separated by the vapor-liquid separating mechanism 2, and finally the condensed water is transmitted back to the inside of the vapor generating mechanism 1 from the output end together.
In the cleaning mode, the controller controls the opening and closing of each end of the loop switching mechanism 5 to disconnect the steam generating mechanism 1, the steam-liquid separating mechanism 2, the condensed liquid returning mechanism 4 and the loop switching mechanism 5 from the heat supply mechanism 3, so that the cleaning mechanism 6 and the heat supply mechanism 3 form an independent loop. The steam in the heat supply mechanism 3 is emptied in advance and then cleaned. The liquid outlet pump 6b and the second liquid return pump 6c are anti-clogging pressure pumps with the same structure. The controller sends a signal to the second liquid returning pump 6c to feed the washing liquid in the washing liquid tank 6a to the heat supplying mechanism 3 through the circuit switching mechanism 5. The washing liquid in the heat supply mechanism 3 is pumped out by the liquid outlet pump 6b and sent into the filter box 6d for filtering. The filtered washing liquid is returned to the washing liquid tank 6a through the liquid return pipe 6 e. The washing liquid is filtered, recycled and utilized after being cleaned, energy is saved, environment is protected, the problem of pollution and blockage of a heating loop is effectively solved, the service life of equipment is prolonged, and the maintenance cost is low.
