Description

Technical Field

[0001] This invention relates to the field of underfloor heating devices, and in particular to an energy-saving integrated underfloor heating and circulation device with intelligent temperature control. Background Technology

[0002] In the field of building heating, underfloor heating systems have become the preferred heating method due to their comfortable and healthy heating characteristics, and are widely used in various types of buildings, including residential, commercial, and public facilities. Underfloor heating systems distribute indoor temperature evenly through radiant heat from the floor, while avoiding the problems of dry air and dust caused by traditional convection heating methods, thus creating a comfortable indoor environment for people.

[0003] However, existing underfloor heating systems have the following problems during use:

[0004] 1. Traditional underfloor heating systems are large in size, occupy a lot of installation space, and affect the overall layout of the building.

[0005] 2. Most heating pipes use simple straight or bent pipe structures, resulting in a short water flow path and limited water residence time in the heating pipes. This leads to insufficient heat exchange with the heating components and low heat exchange efficiency.

[0006] 3. Over long-term use, scale and impurities easily accumulate inside the underfloor heating pipes and on the surface of the heating devices. This scale and impurities reduce heating efficiency and increase energy consumption. Currently, cleaning underfloor heating pipes mainly relies on external equipment, which requires connecting the cleaning equipment to the underfloor heating system, making the process cumbersome.

[0007] Therefore, an energy-saving integrated underfloor heating and circulation device with intelligent temperature control is proposed. Summary of the Invention

[0008] In view of this, the present invention provides an energy-saving integrated underfloor heating and circulation device with intelligent temperature control, so as to solve or alleviate one of the technical problems existing in the prior art, and at least provide a beneficial option.

[0009] The technical solution of this invention is implemented as follows: an intelligent temperature-controlled energy-saving floor heating and circulation integrated device includes a shell assembly, and the shell assembly is internally provided with a circulation heating assembly, a flushing assembly and a control assembly;

[0010] The circulating heating assembly includes an inlet pipe, a first filter, a first electric valve, a water distribution tank, a serpentine pipe, a heating rod, a spiral guide plate, a water collection tank, an outlet pipe, a temperature and pressure transmitter, a circulating pump, a return pipe, a second filter, a second electric valve, and a fifth electric valve.

[0011] The inlet pipe is equipped with a first filter and a first electric valve. One end of the inlet pipe is connected to a water distribution tank. A plurality of serpentine tubes are evenly connected to one side of the water distribution tank. A heating rod is installed inside the serpentine tube. A spiral guide plate is fixedly connected between the serpentine tube and the heating rod. One end of the serpentine tube is connected to a water collection tank. One side of the water collection tank is connected to an outlet pipe. A temperature and pressure transmitter, a circulation pump, and a fifth electric valve are installed on the outlet pipe. One side of the water distribution tank is connected to a return water pipe. A second filter and a second electric valve are installed on the return water pipe.

[0012] When the underfloor heating system is working, the second and fifth electric valves open, the controller starts the circulation pump, which drives the circulation water to flow. The water tank distributes the water to each serpentine tube, and the heating rods inside the serpentine tubes start working to heat the water. At the same time, the spiral guide plate forces the water to rotate and turbulent, allowing for full and efficient heat exchange between the water and the surface of the heating rods, thus improving heat transfer efficiency.

[0013] A further preferred embodiment: a drain valve is installed on the first filter and the second filter, and an insulation box is fixedly connected to the outer wall of the serpentine tube, the interior of the insulation box being filled with insulation cotton.

[0014] A further preferred embodiment: the flushing assembly includes a first flushing pipe, a third electric valve, and a flushing pump;

[0015] The outer wall of the water inlet pipe is connected to a first flushing pipe, on which a third electric valve and a flushing pump are installed.

[0016] A further preferred embodiment: the flushing assembly further includes an injection pipe, a first check valve, an injection box, a motor, a guide rail, a screw, a slider, a piston block, an outlet pipe, a second check valve, a storage cylinder, and an inlet.

[0017] The outer wall of the first flushing pipe is connected to a material injection pipe, on which a first check valve is installed. One end of the material injection pipe is connected to a material injection box, which has an internal cavity. A motor is installed on one side of the material injection box, and a guide rail is fixedly connected to the other side. A screw is rotatably connected to the inner wall of the guide rail, and one end of the screw is fixedly connected to the output shaft of the motor. A slider is threaded to the outer wall of the screw, and a piston block is fixedly connected to the top of the slider. The cavity of the material injection box is connected to a discharge pipe, on which a second check valve is installed. The top of the discharge pipe is connected to a storage cylinder, and the top of the storage cylinder has a feed inlet.

[0018] A further preferred embodiment: the slider is slidably connected to the inner wall of the guide rail, and the piston block is slidably connected to the inner wall of the filling box cavity.

[0019] A further preferred embodiment: one end of the first flushing tube is connected to a mixing tube.

[0020] A further preferred embodiment: one end of the mixing tube is connected to a second flushing tube, and a fourth electric valve is installed on the second flushing tube.

[0021] The controller performs periodic cleaning by controlling the third and fourth electric valves and the flushing pump to open, switching the drain valves on the two sets of filters to connect the filters with the drain pipes at their bottom, closing the inlet and circulating water channels, and closing the first, second, and fifth electric valves. The flushing water enters the flushing pipeline from the first flushing pipe.

[0022] Cleaning agent is added to the storage cylinder through the inlet. The cleaning agent in the storage cylinder enters the injection box through the outlet pipe. The controller starts the motor, which drives the screw to rotate. The screw drives the slider to slide on the inner wall of the guide rail. The slider drives the piston block to slide in the cavity of the injection box, injecting the cleaning agent into the first flushing pipe at a uniform speed through the injection pipe.

[0023] The mixing pipe is used to mix the flushing water and cleaning agent. The mixed flushing liquid enters the collection tank through the second flushing pipe. Since one end of the outlet pipe is closed, it flows in reverse through the serpentine pipe to the inlet and return pipes. After the flushing liquid has finished rinsing the filter, the sewage is discharged through the drain pipe below the filter because the drain valve on the filter has been switched.

[0024] A further preferred embodiment includes a protective shell, a mounting plate, and mounting holes.

[0025] The top and bottom of the protective shell are symmetrically fixedly connected with mounting plates, and the front surface of the mounting plates is provided with mounting holes.

[0026] A further preferred embodiment: the top of the protective shell is hinged to a cover plate, and a handle is fixedly connected to the top of the cover plate.

[0027] A further preferred embodiment: the front surface of the protective shell is fixedly connected to a front panel by bolts, heat dissipation holes are evenly opened on one side of the protective shell, and a partition is fixedly connected to the inner side wall of the protective shell.

[0028] A further preferred embodiment: the control component includes a mounting base, a power module, and a controller;

[0029] The inner wall of the protective shell is fixedly connected to a mounting base, and the inner wall of the mounting base is equipped with a power module and a controller.

[0030] A further preferred embodiment: the front surface of the front panel is equipped with an operation panel, and the front surface of the operation panel is equipped with a touch screen.

[0031] A further preferred embodiment: the controller is signal-connected to the temperature and pressure transmitter, and the controller is electrically connected to the filter, electric valve, circulating pump, flushing pump, and motor.

[0032] The temperature and pressure transmitter on the outlet pipe monitors the water flow temperature and pressure in real time and feeds the data back to the controller. If the water temperature does not reach the set value, the power of the heating element is increased until it reaches its maximum value. Once the water temperature reaches the set range, the power of the heating element is gradually reduced to achieve intelligent temperature control.

[0033] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0034] I. This invention integrates the circulating heating component, flushing component, and control component inside the housing component, achieving a high degree of integration of the main components of the underfloor heating system, saving installation space, improving the compactness of the equipment, and meeting the usage requirements of limited installation space.

[0035] Second, this invention uses a design that combines a serpentine tube, an internal heating rod, and a spiral guide plate for circulating heating, which extends the water flow path and forces the water flow to rotate and turbulent, allowing the water flow to exchange heat with the surface of the heating rod fully and efficiently, improving heat conduction efficiency and saving energy.

[0036] Third, by turning on the flushing pump and the corresponding electric valve, the present invention can perform reverse flushing of the pipeline, remove the impurities and scale deposited in the pipeline, restore the heat exchange efficiency of the system, and achieve the function of regular cleaning without the need for external equipment. The operation is simple and convenient.

[0052] like Figures 1-7 As shown, this embodiment of the invention provides an energy-saving integrated underfloor heating and circulation device with intelligent temperature control, including a housing assembly 10, and the housing assembly 10 is provided with a circulation heating assembly 20, a flushing assembly 30 and a control assembly 40.

[0053] The circulating heating assembly 20 includes an inlet pipe 21, a first filter 22, a first electric valve 23, a water distribution tank 24, a serpentine pipe 25, a heating rod 26, a spiral guide plate 27, a water collection tank 28, an outlet pipe 29, a temperature and pressure transmitter 210, a circulating pump 211, a return pipe 212, a second filter 214, a second electric valve 215, and a fifth electric valve 217.

[0054] A first filter 22 and a first electric valve 23 are installed on the inlet pipe 21. One end of the inlet pipe 21 is connected to a water distribution tank 24. Several serpentine tubes 25 are evenly connected to one side of the water distribution tank 24. A heating rod 26 is installed inside the serpentine tube 25. A spiral guide plate 27 is fixedly connected between the serpentine tube 25 and the heating rod 26. One end of the serpentine tube 25 is connected to a water collection tank 28. One side of the water collection tank 28 is connected to an outlet pipe 29. A temperature and pressure transmitter 210, a circulation pump 211, and a fifth electric valve 217 are installed on the outlet pipe 29. One side of the water distribution tank 24 is connected to a return pipe 212. A second filter 214 and a second electric valve 215 are installed on the return pipe 212.

[0055] When the underfloor heating system is working, the second electric valve 215 and the fifth electric valve 217 are opened, and the controller 43 controls the circulation pump 211 to start, driving the circulation water to flow. The water distribution tank 24 distributes the water to each serpentine tube 25, and the heating rod 26 inside the serpentine tube 25 starts to work to heat the water flow. At the same time, the spiral guide plate 27 forces the water flow to rotate and turbulent, so that the water flow and the surface of the heating rod 26 can fully and efficiently exchange heat, improving the heat conduction efficiency.

[0056] The inlet pipe 21 connects to the external water supply system, while the outlet pipe 29 and return pipe 212 connect to the two ends of the underfloor heating network system, respectively. The water pressure supplied by the external water supply system is the same as the preset water pressure of the underfloor heating circulation system, thus ensuring the balance of internal and external water pressure after water replenishment. The heating rod 26 is equipped with a heating wire, which increases the temperature of the heating rod 26 to heat the underfloor heating circulating water. The drain valve on the filter can switch the connection ends of the pipes to complete automatic cleaning.

[0057] In this embodiment, specifically: drain valves are installed on the first filter 22 and the second filter 214; an insulation box 216 is fixedly connected to the outer wall of the serpentine tube 25; the interior of the insulation box 216 is filled with insulation cotton; the insulation box 216 and the insulation cotton inside it can reduce the heat loss of the heating pipe and further save energy; a filter screen is installed inside the filter to trap impurities; and the drain valve is an electric switching valve.

[0058] In this embodiment, specifically: the flushing assembly 30 includes a first flushing pipe 31, a third electric valve 32, and a flushing pump 33;

[0059] The outer wall of the inlet pipe 21 is connected to the first flushing pipe 31. The first flushing pipe 31 is equipped with a third electric valve 32 and a flushing pump 33. The controller 43 performs periodic cleaning work by controlling the opening of the first electric valve 23, the second electric valve 215, the third electric valve 32, the fourth electric valve 318, and the flushing pump 33. The drain valves on the two sets of filters are switched to connect the filters with the drain pipes at their bottoms. The inlet and circulating water channels are closed, the fifth electric valve 217 is closed, and the flushing water enters the flushing pipeline from the first flushing pipe 31.

[0060] In this embodiment, specifically: the flushing assembly 30 also includes a material injection pipe 34, a first check valve 35, a material injection box 36, a motor 37, a guide rail 38, a screw 39, a slider 310, a piston block 311, a discharge pipe 312, a second check valve 313, a storage cylinder 314, and a feed inlet 315;

[0061] The outer wall of the first flushing pipe 31 is connected to a material injection pipe 34, on which a first check valve 35 is installed. One end of the material injection pipe 34 is connected to a material injection box 36, which has an internal cavity. A motor 37 is installed on one side of the material injection box 36, and a guide rail 38 is fixedly connected to the other side. A screw 39 is rotatably connected to the inner wall of the guide rail 38. One end of the screw 39 is fixedly connected to the output shaft of the motor 37. A slider 310 is threadedly connected to the outer wall of the screw 39, and a piston block 311 is fixedly connected to the top of the slider 310. The cavity of the material injection box 36 is connected to a discharge pipe 312, on which a second check valve 313 is installed. The top of the discharge pipe 312 is connected to a storage cylinder 314, and the top of the storage cylinder 314 is provided with a feed inlet 315. Cleaning agent is added into the storage cylinder 314 through the feed inlet 315. The cleaning agent in the storage cylinder 314 enters the injection box 36 through the discharge pipe 312. The controller 43 controls the motor 37 to start. The motor 37 drives the screw 39 to rotate. The screw 39 drives the slider 310 to slide on the inner side wall of the guide rail 38. The slider 310 drives the piston block 311 to slide in the cavity of the injection box 36, injecting the cleaning agent into the first flushing pipe 31 at a uniform speed through the injection pipe 34. The method of injecting cleaning agent meets the need for slow and uniform injection of small flow rate cleaning agent during the cleaning process.

[0062] The top of the feed inlet 315 is detachably connected to an end cap. When it is necessary to add cleaning agent into the storage cylinder 314, the cover plate 14 and the end cap can be opened to add cleaning agent into the storage cylinder 314.

[0063] In this embodiment, specifically: the slider 310 is slidably connected to the inner wall of the guide rail 38, the piston block 311 is slidably connected to the inner wall of the cavity of the injection box 36, the cleaning agent stored in the storage cylinder 314 enters the cavity of the injection box 36 in a metered manner under the action of gravity, and during the injection of cleaning agent, two sets of check valves can prevent the cleaning agent and water from flowing in reverse, thus completing the uniform metered injection.

[0064] In this embodiment, specifically: one end of the first rinsing pipe 31 is connected to a mixing pipe 316, which is used to mix the rinsing water and the cleaning agent to improve the cleaning effect.

[0065] In this embodiment, specifically: one end of the mixing pipe 316 is connected to the second flushing pipe 317, and the second flushing pipe 317 is equipped with a fourth electric valve 318. One end of the second flushing pipe 317 is connected to the water collection tank 28. The mixed flushing liquid enters the water collection tank 28 through the second flushing pipe 317. Since one end of the outlet pipe 29 is closed, the flushing liquid flows in the opposite direction to the inlet pipe 21 and the return pipe 212 through the serpentine pipe 25. After the flushing liquid completes the flushing of the filter, since the drain valve on the filter has switched the pipeline, the sewage will be discharged through the drain pipe below the filter.

[0066] In this embodiment, specifically: the housing assembly 10 includes a protective shell 11, a mounting plate 12, and mounting holes 13;

[0067] The top and bottom of the protective shell 11 are symmetrically fixed with mounting plates 12. The front surface of the mounting plate 12 is provided with mounting holes 13, which can be used to fix the integrated underfloor heating and circulation device to the wall. The mounting holes 13 facilitate fixing with fixing bolts.

[0068] The protective housing 11 protects the internal components from damage caused by external forces.

[0069] In this embodiment, specifically: a cover plate 14 is hinged to the top of the protective shell 11, and a handle 15 is fixedly connected to the top of the cover plate 14. The cover plate 14 is used to close the top inspection port. By opening the cover plate 14, the inspection and maintenance of each component is more convenient, which improves the maintenance efficiency of the equipment. The cover plate 14 can be fixed by bolts, magnetic attraction or buckle to prevent accidental opening. The handle 15 makes it convenient for users to open and close the cover plate 14.

[0070] In this embodiment, specifically: a front panel 16 is fixedly connected to the front surface of the protective shell 11 by bolts; heat dissipation holes 17 are evenly distributed on one side of the protective shell 11; a partition 18 is fixedly connected to the inner wall of the protective shell 11. The partition 18 is used to divide the internal space of the protective shell 11 into different temperature zones to prevent the heat from the lower heating area from affecting the operating temperature of the electrical equipment above. The heat dissipation holes 17 are used to dissipate heat from the electrical equipment. If the power of the electrical equipment is large, a cooling fan can be added to improve the heat dissipation efficiency. The front panel 16 adopts a detachable structure to facilitate the disassembly and maintenance of internal components.

[0071] In this embodiment, specifically: the control component 40 includes a mounting base 41, a power module 42, and a controller 43;

[0072] The inner wall of the protective shell 11 is fixedly connected to the mounting base 41. The inner wall of the mounting base 41 is equipped with a power module 42 and a controller 43. The power module 42 provides stable power support for the entire device, while the controller 43 is responsible for coordinating the operation of each component. The power module 42 selects an appropriate rated voltage according to different application scenarios. The power module 42 is a common technical means in existing underfloor heating devices, which will not be described in detail here. The controller 43 includes a central processing unit, a memory, an analog-to-digital conversion module, and multiple input / output interfaces. The memory stores various programs for the operation of the integrated underfloor heating cycle device.

[0073] In this embodiment, specifically: an operation panel 44 is installed on the front surface of the front panel 16, and a touch screen 45 is installed on the front surface of the operation panel 44. The operation panel 44 and the touch screen 45 facilitate the user's operation of the integrated underfloor heating and circulation device.

[0074] In this embodiment, specifically: the controller 43 is signal-connected to the temperature and pressure transmitter 210, and the controller 43 is electrically connected to the filter, electric valve, circulation pump 211, flushing pump 33 and motor 37. The temperature and pressure transmitter 210 detects the water temperature and pressure in the underfloor heating system pipeline, and the controller 43 controls the device to perform intelligent temperature control and automatic water replenishment.

[0075] When the present invention is in operation: the inlet pipe 21 is connected to the external water supply system, the outlet pipe 29 and the return pipe 212 are respectively connected to the two ends of the underfloor heating network system, and the bottom of the two sets of filters are connected to the sewage pipe.

[0076] After the system starts, the first electric valve 23 opens, and water enters through the inlet pipe 21. It is then filtered by the first filter 22 to reduce impurities. The filtered water enters the circulation pipe, ensuring a complete water circulation and sufficient circulating water pressure within the underfloor heating system. After the water intake is complete, the first electric valve 23 closes. If the water pressure is insufficient during the operation of the underfloor heating system, water is replenished again through the inlet pipe 21 until the circulating water pressure reaches the preset range.

[0077] Users can set the desired temperature range on the control panel 44 via the touch screen 45 and activate the intelligent temperature control and automatic water replenishment function.

[0078] When the underfloor heating system is working, the second electric valve 215 and the fifth electric valve 217 are opened, and the controller 43 controls the circulation pump 211 to start, driving the circulation water to flow. The water distribution tank 24 distributes the water to each serpentine tube 25, and the heating rod 26 inside the serpentine tube 25 starts to work to heat the water flow. At the same time, the spiral guide plate 27 forces the water flow to rotate and turbulent, so that the water flow and the surface of the heating rod 26 can fully and efficiently exchange heat, improving the heat conduction efficiency.

[0079] The heated water flows into the collection tank 28 and then out through the outlet pipe 29. The temperature and pressure transmitter 210 on the outlet pipe 29 monitors the water temperature and pressure in real time and feeds the data back to the controller 43. If the water temperature does not reach the set value, the power of the heating rod 26 is increased until the power of the heating rod 26 reaches its maximum value. After the water temperature reaches the set range, the power of the heating rod 26 is gradually reduced to achieve intelligent temperature control.

[0080] After the system has been running for a period of time, impurities and scale accumulate in the pipes. Controller 43 performs periodic cleaning by opening the third electric valve 32, the fourth electric valve 318, and the flushing pump 33. The drain valves on the two sets of filters switch, connecting the filters to their bottom drain pipes. The inlet and circulating water channels are closed, and the first electric valve 23, the second electric valve 215, and the fifth electric valve 217 are closed. Flushing water enters the flushing pipeline from the first flushing pipe 31, and cleaning agent is added to the storage tank 314 through the inlet 315. The cleaning agent inside enters the injection tank 36 through the discharge pipe 312. The controller 43 controls the motor 37 to start, and the motor 37 drives the screw 39 to rotate. The screw 39 drives the slider 310 to slide on the inner side wall of the guide rail 38. The slider 310 drives the piston block 311 to slide in the cavity of the injection tank 36, injecting the cleaning agent into the first flushing pipe 31 at a uniform speed through the injection pipe 34. After the cleaning agent is mixed with the flushing water in the mixing pipe 316, it performs a reverse flushing of the pipeline, removing impurities and scale deposited on the surface of the heating rod 26 and inside the pipe, and restoring the heat exchange efficiency of the system.

[0081] After rinsing, the system resumes normal heating and circulation. The entire process can achieve regular cleaning without the need for external equipment. It is simple and convenient to operate, and its highly integrated design saves installation space, improves the compactness of the equipment, and meets the needs of users with limited installation space.
