Description

[0002] The hot water ground radiation heating system, usually simply referred to as the floor heating system, is a modern heating mode, which utilizes hot water as a heat medium and evenly spreads heat to indoor space through the pipeline network laid under the floor. The floor heating system mainly consists of a heat source (such as a boiler, a water heater, etc.), a main water pipe, a branch water collector, a floor heating branch pipe, a control system, and an insulation layer. After being heated in the heat source, the hot water is transported to each floor heating branch pipe through the main water pipe to enter the heat dissipation layer under the floor, and then the heat is spread to the indoor space in a radiation manner.

[0058] The structure of the branch ball valve commonly used in the market can only play an opening and closing role, cannot control and adjust the water flow balance, and when applied to the distribution water collector 10 and the floor heating system, indoor heat dissipation temperature imbalance and energy waste are easily caused.

[0059] The anti-scale valve structure 1 of the utility model, through setting the sealing part 1241 and the flow control part 1242, the sealing part 1241 plays a role of sealing the branch through hole 131, and the flow control part 1242 plays a role of controlling and adjusting the branch flow. The first valve rod 122 is driven to rotate by the anti-scale valve driving mechanism 15, the second valve rod 123 drives the sealing assembly 124 to move along the axial direction of the scale stopping valve body 121, the flow control part 1242 is inserted into the branch through hole 131 or away from the branch through hole 131, so that the relative position of the flow through hole 12421 and the branch seat 13 is changed to adjust the flow area of the flow through hole 12421, and when the flow control part 1242 is inserted into the branch through hole 131, the flow area of the flow through hole 12421 is gradually reduced, so that the flow control and adjustment of the branch can be realized.

[0060] Further, when the flow control part 1242 is inserted into the branch port 131, the outer circumferential wall of the flow control part 1242 abuts against the inner circumferential wall of the branch seat 13, and when the flow control part 1242 rotates, the flow control part 1242 can cut the dirt and impurities on the inner circumferential wall of the branch seat 13, preventing the dirt and impurities from adhering to the branch seat 13.

[0061] Specifically, the sealing part 1241 and the second valve rod 123 can be threadedly connected, facilitating disassembly and replacement of the sealing assembly 124. Specifically, the flow through hole 12421 can be rectangular, triangular, trapezoidal or the like.

[0062] In other embodiments, the sealing assembly 124 can only include the sealing part 1241, and the sealing part 1241 is provided with the first sealing gasket 12411 matched with the end surface of the branch seat 13. The dirt-proof valve driving mechanism 15 drives the first valve rod 122 to rotate, so that the second valve rod 123 drives the sealing part 1241 to move along the axial direction of the dirt-proof stop valve body 121. At this time, by controlling the distance between the sealing part 1241 and the branch seat 13, the opening size of the branch port 131 is controlled, thereby realizing the flow control and adjustment of the branch.

[0063] Further, the dirt-proof valve driving mechanism 15 is a first adjusting hand wheel or a motor, which drives the first valve rod 122 to rotate. Further, the dirt-proof valve driving mechanism 15 is provided with the visible flow scale for directly displaying the rotation number of the first valve rod 122, thereby indicating the relative position between the flow control part 1242 and the branch seat 13, and directly indicating the flow condition.

[0064] Please refer to Figures 4 to 5 The utility model also provides a distribution water collector, including water supply combination body 101 and backwater combination body 102, the water supply combination body 101 includes several like above described any kind of dirt-proof valve structure 1 of the dirt-proof valve structure 1, and the main pipeline 11 of multiple dirt-proof valve structure 1 is connected from head to tail to make multiple dirt-proof stop valve core assembly 12 interval arrangement.

[0065] Please refer to Figure 6The backwater assembly 102 comprises a plurality of temperature control valve structures 2 corresponding to the scale prevention valve structure 1; the temperature control valve structure 2 comprises a backwater pipeline 21, a scale prevention temperature control valve core assembly 22, a backwater branch seat 23 and a temperature control valve driving mechanism 24; the scale prevention temperature control valve core assembly 22 and the backwater branch seat 23 are oppositely arranged along the outer peripheral wall of the backwater pipeline 21, and a plurality of backwater pipelines 21 are connected in a head-to-tail mode to arrange a plurality of scale prevention temperature control valve core assemblies 22; the temperature control valve driving mechanism 24 is detachably connected with the scale prevention temperature control valve core assembly 22, and the temperature control valve driving mechanism 24 drives the scale prevention temperature control valve core assembly 22 to be inserted into the backwater pipeline 21 and movably connected with the backwater branch seat 23.

[0066] The water distribution device 10 can avoid the rust, mud and other impurities in water from entering the threaded cavity 1231, and avoid the first valve rod 122 and the second valve rod 123 from being stuck during adjustment. Meanwhile, the impurities can be prevented from being deposited for a long time to cause the scale prevention temperature control valve core assembly 22 and the second valve rod 123 to be blocked. The branch seat 13 is protruded towards the inside of the main pipeline 11, and the dirt is not easy to accumulate at the branch valve port 131, so that the dirt can be effectively prevented from being deposited and accumulated at the branch valve port to cause the branch valve port to be blocked, and the sealing assembly 124 cannot seal the branch valve port. The problems of the valve rod being blocked due to scale and causing adjustment difficulty, and the branch valve port being blocked due to scale and causing the hot water flow to be uneven or the branch valve port to be not tightly sealed are solved.

[0067] The opening and closing of the temperature control valve structure 2 is used for controlling whether the hot water in the floor heating branch pipe is allowed to flow into the backwater pipeline 21. In an embodiment, the structure of the backwater pipeline 21 is the same as that of the main pipeline 11, that is, the mounting port and the branch valve port are also arranged on the outer peripheral wall of the backwater pipeline 21. The structure of the scale prevention temperature control valve core assembly 22 is the same as that of the scale prevention stop valve core assembly 12, and the structure of the backwater branch seat 23 is the same as that of the branch seat 13, so that the temperature control valve structure 2 has the same functions and effects as the scale prevention valve structure 1.

[0068] In other embodiments, the structure of the scale prevention temperature control valve core assembly 22 can be different from that of the scale prevention stop valve core assembly 12, but it should be noted that the connection modes among the backwater pipeline 21, the scale prevention temperature control valve core assembly 22 and the backwater branch seat 23 are the same as those among the main pipeline 11, the scale prevention stop valve core assembly 12 and the branch seat 13.

[0069] Please refer toFigure 6 Further, the scale-inhibiting temperature control valve core assembly 22 includes a scale-inhibiting temperature control valve body 221, a third valve rod 222, a corrugated sleeve 223, and a sealing seat 224.

[0070] The scale-inhibiting temperature control valve body 221 is inserted into the return water pipeline 21, and the scale-inhibiting temperature control valve body 221 is formed with a second moving cavity 2211 for the third valve rod 222 to move up and down. One end of the third valve rod 222 is connected with the temperature control valve driving mechanism 24, and the other end of the third valve rod 222 extends into the return water pipeline 21 from the second moving cavity 2211 and is fixedly connected with the sealing seat 224.

[0071] The second moving cavity 2211 is provided with a first reset spring 2212, the first reset spring 2212 is sleeved on the outer circumferential side of the third valve rod 222, and the upper end of the first reset spring 2212 is fixedly connected with the third valve rod 222, and the lower end of the first reset spring 2212 is fixedly connected with the scale-inhibiting temperature control valve body 221.

[0072] The section of the third valve rod 222 between the scale-inhibiting temperature control valve body 221 and the sealing seat 224 is sleeved with the corrugated sleeve 223, one end of the corrugated sleeve 223 is fixedly connected with the scale-inhibiting temperature control valve body 221, and the other end of the corrugated sleeve 223 is fixedly connected with the end of the third valve rod 222 close to the sealing seat 224, and the corrugated sleeve 223 expands and contracts with the up and down movement of the third valve rod 222.

[0073] The return water branch seat 23 is provided with a return water through port 231 matched with the sealing seat 224, and the end of the return water branch seat 23 close to the scale-inhibiting temperature control valve body 221 is protrudingly arranged towards the inside of the return water pipeline 21.

[0074] The temperature control valve driving mechanism 24 is connected with the end of the third valve rod 222 away from the sealing seat 224, so as to drive the third valve rod 222 to move along the axial direction of the scale-inhibiting temperature control valve body 221, so that the sealing seat 224 seals or opens the return water through port 231.

[0075] By sleeving the section of the third valve rod 222 between the scale-inhibiting temperature control valve body 221 and the sealing seat 224 with the corrugated sleeve 223, that is, by placing the section of the third valve rod 222 in the return water pipeline 21 in the corrugated sleeve 223, the direct contact between the third valve rod 222 and the water in the return water pipeline 21 can be avoided, the corrugated sleeve 223 can protect the third valve rod 222, and the phenomenon of jamming or the like can be avoided when the third valve rod 222 moves relatively with the scale-inhibiting temperature control valve body 221 due to scale formation of the third valve rod 222.

[0076] It should be noted that the material of the corrugated sleeve 223 is an elastic material, when the third valve rod 222 moves along the axial direction of the scale control temperature valve body 221, the corrugated sleeve 223 stretches and contracts with the up and down movement of the third valve rod 222, because the two ends of the corrugated sleeve 223 are fixedly connected with the scale control temperature valve body 221 and the sealing seat 224 respectively, so that the section of the return water pipeline 21 of the third valve rod 222 is always located inside the corrugated sleeve 223. When the third valve rod 222 moves downward, the corrugated sleeve 223 stretches downward, and when the third valve rod 222 moves upward, the corrugated sleeve 223 rebounds upward, which can avoid the corrugated sleeve 223 being in a stretched state for a long time, and reduce the wear of the corrugated sleeve 223.

[0077] Further, the temperature valve driving mechanism 24 is detachably connected with the scale control temperature valve body 221 (such as through threaded connection), and the driving end of the temperature valve driving mechanism 24 is movably connected with the third valve rod 222. When the temperature valve driving mechanism 24 moves downward, it can drive the third valve rod 222 to move downward, at this time, the first reset spring 2212 is compressed; when the temperature valve driving mechanism 24 moves upward, the first reset spring 2212 rebounds under the action of the restoring force, and drives the third valve rod 222 to also move upward to reset.

[0078] Further, the sealing seat 224 is provided with a second sealing gasket 225 on the end face facing the return water branch seat 23, which can seal the return water through port 231.

[0079] Further, a plurality of second sealing rings 226 are arranged between the outer peripheral wall of the third valve rod 222 and the scale control temperature valve body 221 to seal the second moving cavity 2211. The second sealing ring 226 can improve the connection sealing between the third valve rod 222 and the scale control temperature valve body 221, and prevent impurities such as silt and rust from entering the second moving cavity 2211.

[0080] Please refer to Figures 6 to 7Further, the temperature control valve driving mechanism 24 is an electric heat actuator, which comprises a fixed nut 241, an actuator fixed seat 242, an execution assembly 243 and a protective cover 244; one end of the fixed nut 241 is threadedly connected with the scale inhibition temperature control valve body 221, and the other end of the fixed nut 241 is detachably connected with the actuator fixed seat 242; the protective cover 244 is sleeved on the outer circumferential side of the actuator fixed seat 242, and an actuator cavity 245 is formed between the protective cover 244 and the actuator fixed seat 242, and the execution assembly 243 is arranged in the actuator cavity 245;

[0081] Please refer to Figures 7 to 8 The execution assembly 243 comprises a temperature bag 2431, a heating sheet 2432, a push rod assembly 2433, a temperature bag fixed block 2434 and a second reset spring 2435, one end of the second reset spring 2435 is fixedly connected with the upper end of the protective cover 244, the other end of the second reset spring 2435 is fixedly connected with the temperature bag fixed block 2434, the end of the temperature bag fixed block 2434 away from the second reset spring 2435 is movably connected with the actuator fixed seat 242, and a containing cavity 24341 for containing the temperature bag 2431 and the push rod assembly 2433 is formed between the temperature bag fixed block 2434 and the actuator fixed seat 242, and the heating sheet 2432 is arranged between the temperature bag fixed block 2434 and the temperature bag 2431.

[0082] The actuator fixed seat 242 is provided with a connecting through hole 2421 for the push rod assembly 2433 to pass through at the end face facing the third valve rod 222, and the containing cavity 24341 is in communication with the connecting through hole 2421; one end of the push rod assembly 2433 is movably connected with the lower end of the temperature bag 2431, and the other end of the push rod assembly 2433 extends into the connecting through hole 2421 and abuts against the third valve rod 222.

[0083] Further, the fixed nut 241 is provided with an installation cavity 2411 penetrating up and down, the installation cavity 2411 is provided with an internal thread, the section of the scale inhibition temperature control valve body 221 located outside the return water pipeline 21 is provided with an external thread matched with the internal thread, so that the fixed nut 241 is threadedly connected with the scale inhibition temperature control valve body 221; the actuator fixed seat 242 is inserted into the installation cavity 2411 and connected with the fixed nut 241, and the end of the third valve rod 222 away from the sealing assembly 124 passes through the installation cavity 2411 and abuts against the push rod assembly 2433. Specifically, the actuator fixed seat 242 and the fixed nut 241 are connected by clamping or threadedly connected.

[0084] Further, the axis of the push rod assembly 2433 coincides with the axis of the third valve rod 222. When the temperature control valve driving mechanism 24 is opened, the heating sheet 2432 generates heat and transfers the heat to the temperature bulb 2431, so that the temperature bulb 2431 expands. The expansion of the temperature bulb 2431 forces the push rod assembly 2433 to move downward, and drives the third valve rod 222 to move downward along the axis of the scale-inhibiting temperature control valve body 221 (at this time, the first return spring 2212 is compressed), so that the sealing seat 224 can move downward to seal the return water passage 231 (i.e. the corresponding return water branch can be closed, and the hot water in the corresponding radiant heating branch pipe stops flowing, so that the radiant heat gradually decreases). When the temperature control valve driving mechanism 24 is closed, the heating sheet 2432 stops generating heat, and the temperature decreases, so that the volume of the temperature bulb 2431 gradually decreases, and under the action of the restoring force of the first return spring 2212, the third valve rod 222 and the push rod assembly 2433 move upward along the axis of the scale-inhibiting temperature control valve body 221, so that the sealing seat 224 is away from the return water passage 231, i.e. the hot water flow between the return water pipeline 21 and the corresponding radiant heating branch pipe is restored.

[0085] Further, the second return spring 2435 is used to press the temperature bulb fixing block 2434 to fix the temperature bulb 2431. When the temperature bulb 2431 expands, a certain force value is generated, and when the third valve rod 222 drives the sealing seat 224 to move downward to seal the return water passage 231, a certain water pressure is generated on the sealing seat 224 at the return water passage 231. The second return spring 2435 can offset part of the pressure to achieve the sealing effect.

[0086] Please refer to Figures 7 to 8 Further, the push rod assembly 2433 includes a top rod 24331, a top block 24332, and a lifting indication block 24333.

[0087] The temperature bulb 2431 is provided with a containing groove 24311 on the end face facing the third valve rod 222, one end of the top rod 24331 is arranged in the containing groove 24311, and the other end of the top rod 24331 penetrates out of the containing groove 24311 and is fixedly connected with the top block 24332.

[0088] One end of the lifting indication block 24333 is fixedly connected with the top block 24332, and the other end of the lifting indication block 24333 extends horizontally away from the top block 24332.

[0089] The side wall of the actuator fixing seat 242 is provided with a through slot 2422 through which the lifting indicating block 24333 passes, one end of the lifting indicating block 24333 away from the top block 24332 extends into the actuator cavity 245 through the through slot 2422, and the lifting indicating block 24333 moves up and down along the through slot 2422;

[0090] An observation window is formed in the side wall of the protective cover 244, and the position of the observation window corresponds to the position of the through slot 2422.

[0091] By arranging the accommodating groove 24311 and arranging the top rod 24331 in the accommodating groove 24311, the overall temperature control valve driving mechanism 24 is more compact, the axial distance between the temperature bulb 2431 and the third valve rod 222 is shortened, the push rod assembly 2433 can be ensured to move a large distance downward, and the third valve rod 222 can be pushed downward to seal the water return opening 231.

[0092] By arranging the lifting indicating block 24333, when the volume change of the temperature bulb 2431 drives the top rod 24331 and the top block 24332 to move, the lifting indicating block 24333 can be driven to move along the through slot 2422 at the same time, at this time, through the observation window formed in the protective cover 244, whether the electric heating actuator performs an execution action can be directly observed, which is helpful for troubleshooting problems in time.

[0093] Please refer to Figure 5 and Figure 9In other embodiments, the temperature control valve driving mechanism 24 can also be provided as a second adjusting hand wheel, including a hand wheel fixing cover 246 and an adjusting hand wheel body 247; the hand wheel fixing cover 246 is threadedly connected with the scale control temperature control valve body 221, and the adjusting hand wheel body 247 is threadedly connected with the hand wheel fixing cover 246; the adjusting hand wheel body 247 is provided with an inner cavity, the top of the inner cavity is provided with a protrusion 2471, the axis of the protrusion 2471 coincides with the axis of the third valve rod 222, and the lower end surface of the protrusion 2471 abuts against the upper end surface of the third valve rod 222. In use, first, the hand wheel fixing cover 246 is threadedly fixed on the scale control temperature control valve body 221, then the adjusting hand wheel body 247 is threadedly connected on the hand wheel fixing cover 246, and the protrusion 2471 abuts against the third valve rod 222, the adjusting hand wheel body 247 is rotated to move the adjusting hand wheel body 247 along the axial direction of the hand wheel fixing cover 246 downward, thereby driving the third valve rod 222 to move along the axial direction of the scale control temperature control valve body 221 downward (at this time, the first return spring 2212 is compressed), thereby driving the sealing seat 224 to move downward to seal the water return opening 231; the adjusting hand wheel body 247 is rotated in the opposite direction to move the adjusting hand wheel body 247 along the axial direction of the hand wheel fixing cover 246 upward, and under the action of the restoring force of the first return spring 2212, the third valve rod 222 moves along the axial direction of the scale control temperature control valve body 221 upward, thereby moving the sealing seat 224 away from the water return opening 231.

[0094] Further, in one of the water distribution devices 10, the temperature control valve driving mechanism 24 can be provided as the electric heating actuator or the second adjusting hand wheel, and the electric heating actuator and the second adjusting hand wheel can be used interchangeably, which can be used flexibly according to user needs, and is conducive to improving the adaptability and application range of the water distribution device 10, and meeting the use needs in different scenarios.

[0095] Please refer to Figures 4 to 5 Further, the water distribution device 10 further includes a plug exhaust valve 103 and a mounting bracket 104, the water supply assembly 101 and the water return assembly 102 are fixedly connected with the mounting bracket 104, and the water supply assembly 101 and the water return assembly 102 are arranged in a staggered manner; the water supply assembly 101 and the water return assembly 102 are respectively connected with the plug exhaust valve 103.

[0096] The mounting bracket 104 plays a role in fixing and supporting the water supply assembly 101 and the water return assembly 102, and can make the layout of the floor heating branch pipes more orderly.

[0097] Further, the plug exhaust valve 103 is connected with the main pipeline 11 and the return water pipeline 21. By arranging the plug exhaust valve 103, the air in the main pipeline 11 or the return water pipeline 21 can be discharged to adjust the pressure in the main pipeline 11 or the return water pipeline 21, so that the safety risk caused by the high water pressure can be avoided.

[0098] Please refer to Figure 4 、 Figure 5 、 Figure 10 and Figure 11 , the utility model also proposes a kind of compartment temperature control system, including heat source, temperature control panel 20, floor heating branch pipe and as above described any one described distribution water heater 10, the water outlet of the heat source is connected with the water supply combination 101, the water inlet of the heat source is connected with the return water combination 102, the water supply combination 101 is connected with the return water combination 102 by floor heating branch pipe;

[0099] The number of the scale prevention valve structure 1, the temperature control valve structure 2 and the temperature control panel 20 is one-to-one corresponding.

[0100] The distribution water heater 10, the heat source (not shown in the figure) provides hot water to the water supply combination 101, and the water outlet of the heat source is connected with the main pipeline 11 in the water supply combination 101, so that the water supply combination 101 can deliver hot water to different indoor areas to achieve heating.

[0101] Specifically, the water supply combination 101 in the distribution water heater 10 includes a plurality of scale prevention valve structures 1, wherein the plurality of main pipelines 11 are connected end to end, the plurality of branch seat 13 are connected with the floor heating branch pipe at one end away from the main pipeline 11, and the plurality of floor heating branch pipes are connected with the corresponding return water branch seat 23 in the return water combination 102 at one end away from the branch seat 13. In use, after the water supply combination 101 is opened (i.e., the branch passage 131 is opened), the hot water in the heat source flows from the first end of the main pipeline 11 to each floor heating branch pipe, and then flows to the return water pipeline 21 from each floor heating branch pipe, and then the hot water flows back to the heat source through the return water pipeline 21, realizing the circulation of hot water. When the floor heating branch pipe flows hot water, it realizes heating in the form of radiant heat. At this time, if one of the temperature control valve structures 2 in the return water combination 102 is closed, the hot water in the corresponding floor heating branch pipe of the temperature control valve structure 2 stops flowing, and the radiant heat of the floor heating branch pipe decreases.

[0102] The split room temperature control system controls whether the corresponding ground heating branch pipe flows in hot water and the flow of the hot water flowing in, so that whether heating or the degree of heating is controlled to the corresponding indoor area; by adjusting each temperature control valve structure 2 in the return water combination 102, whether the hot water in the ground heating branch pipe is allowed to flow into the return water pipeline 21 is controlled, so as to realize the adjustment of the temperature of the indoor area.

[0103] By setting the temperature control panel 20, the temperature control panel 20 is electrically connected with the temperature control valve driving mechanism 24, the flow rate of each ground heating branch pipe can be adjusted according to the real-time temperature of each indoor area, the temperature control valve driving mechanism 24 is adjusted to control the flow rate of each ground heating branch pipe, and the automatic control and adjustment of the indoor area heating temperature are realized.

[0104] Please refer to Figures 10 to 11 Further, the temperature control panel 20 comprises a panel base 202 and a panel upper cover 201 arranged on the panel base 202, the panel upper cover 201 is provided with a sensor 2011, and the panel base 202 is provided with a microcomputer control chip 2021 and a terminal interface 203.

[0105] The temperature control panel 20 is installed on the wall surface of each indoor area, and the corresponding wires and wire boxes need to be pre-buried when the temperature control panel 20 is installed, the temperature control valve driving mechanism 24 and the temperature control panel 20 are connected through the pre-buried wires; the panel base 202 is installed on the wire box through screws, and the panel upper cover 201 is arranged on the upper end of the panel base 202.

[0106] It should be noted that the panel upper cover 201 can be provided with a button for users to set parameters, the temperature of the indoor area can be monitored in real time by setting the sensor 2011, when the temperature of the indoor area monitored by the sensor 2011 does not meet the user's set parameters, the microcomputer control chip 2021 can send instructions to control the temperature control valve driving mechanism 24 to act, so as to realize accurate temperature monitoring and regulation, so that the indoor temperature realizes the effect of constant temperature.

[0107] For example, more specifically, when the temperature control valve driving mechanism 24 is the electric heating actuator, the temperature of the indoor area is monitored in real time by the sensor 2011, and when the temperature of one of the indoor areas is higher than the user set parameter, the microcomputer control chip 2021 in the corresponding temperature control panel 20 will command the electric heating actuator to start, so that the heating sheet 2432 generates heat and transmits heat to the temperature bag 2431, so that the temperature bag 2431 is heated and expanded, and the push rod assembly 2433 is forced to move downward after the volume of the temperature bag 2431 expands, driving the third valve rod 222 to move downward along the axis of the scale-inhibiting temperature control valve body 221 (at this time, the first return spring 2212 is compressed), so that the sealing seat 224 can move downward to seal the return water passage 231 (i.e. the corresponding return water branch can be closed, the hot water in the corresponding floor heating branch pipe stops flowing, so that the radiant heat of the corresponding indoor area gradually decreases); in this way, when it is monitored that the temperature of the indoor area is lower than the user set parameter, the microcomputer control chip 2021 in the corresponding temperature control panel 20 will command the electric heating actuator to be powered off, the heating sheet 2432 stops generating heat, and the temperature decreases, so that the volume of the temperature bag 2431 gradually decreases, so that the push rod assembly 2433 moves upward, and under the action of the restoring force of the first return spring 2212, the third valve rod 222 moves upward along the axis of the scale-inhibiting temperature control valve body 221, so that the sealing seat 224 is away from the return water passage 231, i.e. the hot water flow between the return water pipeline 21 and the corresponding floor heating branch pipe is restored, so that the hot water in the floor heating branch pipe is recirculated and delivered, so that the temperature of the indoor area starts to gradually rise, so as to achieve the effect of constant temperature of the indoor area.

[0108] The chamber temperature control system has the advantages that the scale-proof valve structure 1, the temperature control valve structure 2 and the temperature control panel 20 are one-to-one correspondingly arranged, i.e. each indoor area can be controlled individually, the flow distribution of each floor heating branch pipe can be optimized, and the intelligent control of the temperature of the indoor area is realized.

[0109] The technical principles of the utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the utility model, and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanations herein, the person skilled in the art can think of other specific embodiments of the utility model without creative labor, and these embodiments will all fall within the protection scope of the utility model.
