Description

Technical Field

[0001] The invention relates to the technical field of floor heating cleaning, and in particular to a self-cleaning floor heating system. Background Art

[0002] Floor heating has a good development situation in the central heating areas in northern my country and has been widely used. However, floor heating is a hidden project. The floor heating pipes are buried under the ground. Users often ignore the daily maintenance of floor heating, so the important link of floor heating cleaning and maintenance is often not taken seriously. Because the quality of central heating water is relatively dirty, it is easy to cause scaling or blockage of filter valves and pipes. The central heating system on the market has a single function, with only a simple manual filter cleaning device and no automatic cleaning device. If it is not cleaned and maintained in time, the heating system will malfunction and cannot be used. If the blockage is serious, the pipeline system has to be dismantled and replaced, which will bring inconvenience to the user's life and economic losses.

[0003] Therefore, it is very necessary to develop an efficient, simple and reliable floor heating self-cleaning system, which can not only perform regular professional cleaning and maintenance of floor heating pipes, but also regularly flush the filter valve filter screen to achieve maintenance-free floor heating system. While users can use floor heating easily, they can avoid wasting time and expenses caused by finding professionals to clean floor heating, and can also avoid economic losses caused by dismantling or replacing pipelines due to failure to maintain the floor heating system in a timely manner. Summary of the invention

[0006] The manifold is connected to a plurality of branch floor heating pipelines, each branch floor heating pipeline is provided with a branch driver, and the branch driver is connected to a control mechanism.

[0007] The manifold comprises a water distribution pipe and a water collection pipe, and the water distribution pipe and the water collection pipe are connected through a branch floor heating pipeline.

[0008] The control mechanism comprises a main controller, a central control box and a slave controller, and the central control box is connected to the main controller and the slave controller.

[0027] The outlet end of the water inlet pipe 8, the inlet end of the first water inlet branch pipe 801, and the inlet end of the second water inlet branch pipe 802 are connected through a three-way pipe fitting.

[0028] In addition to conventional room-by-room and household-by-household temperature control, the present invention also has working states such as normal heating, pipeline cleaning, conventional filter cleaning, strong filter cleaning, and floor heating system shutdown.

[0029] Normal heating state: The user operates the main controller 10 manually, by mobile phone or by presetting, so that it sends a normal heating instruction to the central control box 4, and the central control box 4 sends an action instruction to each control element. At this time, the high-pressure pulse pump 1 and the first electric ball valve 2 are closed, and the second water inlet branch pipe 802 is in a closed state; the first automatic filter valve driver 601 on the automatic filter valve 6 is in an open state, and the second automatic filter valve driver 602 is in a closed state; the main controller 10 and the slave controller 3 make the branch drivers 501 on each branch of the manifold 5 in the automatic working state of the room temperature setting; the second electric ball valve driver 701 on the second electric ball valve 7 is in an open state. In this state, hot water enters the first water inlet branch pipe 801 from the water inlet pipe 8, and after being circulated through the manifold 5, it returns to the return pipe 9. At this time, the entire system is in a normal heating state.

[0030] Pipe cleaning state: The user operates the main controller 10 manually, by mobile phone or by presetting, so that it sends a pipeline cleaning instruction to the central control box 4, and the central control box 4 sends an action instruction to each control element. At this time, the high-pressure pulse pump 1 and the first electric ball valve 2 are open, and the second water inlet branch 802 is in a smooth state; the first automatic filter valve driver 601 on the automatic filter valve 6 is in a closed state, the second automatic filter valve driver 602 is in a closed state, and the first water inlet branch 801 is in a closed state; one of the branch drivers 501 on the manifold 5 is in an open state, and the rest are closed; the second electric ball valve driver 701 on the second electric ball valve 7 is in an open state. In this state, hot water enters the second water inlet branch 802 from the water inlet pipe 8. After the heating water pressure and the high-pressure pulse pump 1 are superimposed, the water flow is in a high-pressure vibration state, passes through a branch opened in the manifold 5, flushes the floor heating pipe of the branch, and finally returns to the return pipe 9. After a period of time, the floor heating pipe of the branch can be cleaned. Under the control of the main controller 10, the branch pipes are cleaned one by one, and the cleaning time can be set according to the user. After the cleaning is completed, the whole system returns to the normal heating state.

[0031] Conventional filter cleaning state: the user operates the main controller 10 manually, by mobile phone or by presetting, so that it sends a filter cleaning instruction to the central control box 4, and the central control box 4 sends an action instruction to each control element. At this time, the high-pressure pulse pump 1 and the first electric ball valve 2 are closed, and the second water inlet branch 802 is in a closed state; the first automatic filter valve driver 601 on the automatic filter valve 6 is in an open state, the second automatic filter valve driver 602 is in an open state, and the first water inlet branch 801 is in a smooth state; the branch driver 501 on each branch of the manifold 5 is in an automatic working state set at room temperature; the second electric ball valve driver 701 on the second electric ball valve 7 is in an open state. In this state, hot water enters the first water inlet branch 801 from the water inlet pipe 8, flows through the filter of the automatic filter valve 6, and flushes the filter and impurities. The flushed sewage enters the return pipe 9 through the sewage pipe 11. The regular filter cleaning time and frequency can be set by the user.

[0032] Filter strong cleaning state: the user operates the main controller 10 manually, by mobile phone or by presetting, so that it sends a filter cleaning instruction to the central control box 4, and the central control box 4 sends an action instruction to each control element. At this time, the high-pressure pulse pump 1 and the first electric ball valve 2 are open, and the second water inlet branch 802 is in a smooth state; the first automatic filter valve driver 601 on the automatic filter valve 6 is in a closed state, the second automatic filter valve driver 602 is in an open state, and the first water inlet branch 801 is in a closed state; the branch driver 501 on each branch of the manifold 5 is in a closed state; the second electric ball valve driver 701 on the second electric ball valve 7 is in an open state. In this state, hot water enters the second water inlet branch 802 from the water inlet pipe 8, and after the heating water pressure and the high-pressure pulse pump 1 are superimposed, the water flow is in a high-pressure vibration state, flows through the filter of the automatic filter valve 6, and strongly flushes the filter and impurities. The flushed sewage enters the return pipe 9 through the sewage pipe 11. The filter cleaning time and frequency can be set by the user. This mode is mainly used when the water quality is dirty and the filter is seriously clogged.

[0033] The floor heating system is turned off: the user operates the main controller 10 manually, by mobile phone or by presetting, so that it sends a filter cleaning instruction to the central control box 4, and the central control box 4 sends an action instruction to each control element. At this time, the high-pressure pulse pump 1 and the first electric ball valve 2 are closed, and the second water inlet branch pipe 802 is in a closed state; the first automatic filter valve driver 601 on the automatic filter valve 6 is in a closed state, the second automatic filter valve driver 602 is in a closed state, and the first water inlet branch pipe 801 is in a closed state; the branch drivers 501 on each branch of the manifold 5 are in a closed state; the second electric ball valve driver 701 on the second electric ball valve 7 is in a closed state. In this state, the water inlet pipe 8 and the return pipe 9 are both in a closed state, and the entire floor heating system stops running.

[0034] This system does not require external natural water or the addition of cleaning agents. The system itself can achieve high-pressure pulse cleaning of the floor heating pipes and the floor heating system, avoiding the phenomenon of floor heating not being hot due to scaling of the floor heating pipes. The cleaning is efficient and has a comparable effect to professional cleaning. The filter can be cleaned conventionally or forcefully to avoid the phenomenon of floor heating not being hot due to insufficient flow caused by filter blockage. The system does not discharge sewage to the outside during the cleaning process, and the hot water supply is not lost, which is very beneficial to the heating conditions of centralized heating. The system can be set to achieve manual or automatic cleaning, and the entire floor heating system can be automatically cleaned and maintained without the need for professional maintenance, which improves the floor heating experience, saves time, and reduces economic expenditure. The system can achieve room and household temperature control, and the system can be set or shut down manually or on a mobile phone.
