Description

Technical Field

[0001] This utility model relates to the field of underfloor heating equipment technology, specifically an underfloor heating water temperature and flow rate control device. Background Technology

[0002] Existing underfloor heating water temperature and flow control technologies have many shortcomings. Regarding flow regulation, most underfloor heating systems lack precise flow control methods, making it difficult to flexibly adjust the water flow in the heating pipes according to actual needs. This not only limits the refined control of heating effects but also affects energy efficiency. For example, when users need to lower the room temperature, traditional systems cannot quickly reduce the water flow to achieve rapid cooling, leading to energy waste; conversely, when there is a need to raise the temperature, they cannot quickly increase the water flow to achieve a rapid recovery of room temperature.

[0003] Existing underfloor heating systems suffer from poor coordination among their components. Wall-mounted fireplaces, water pumps, flow meters, and other equipment operate independently, lacking unified and coordinated control. This prevents the heating system from achieving optimal performance in actual operation, reducing overall system efficiency. Furthermore, traditional underfloor heating systems have flaws in their liquid distribution design, resulting in uneven liquid distribution and inconsistent water temperatures within the pipes, affecting the uniformity of heating.

[0004] In summary, existing underfloor heating systems suffer from problems such as delayed water temperature regulation, inflexible flow rate regulation, poor equipment coordination, and uneven liquid distribution. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a floor heating water temperature and flow rate control device that can accurately regulate water temperature and flow rate, realize the coordinated work of various components and achieve uniform liquid distribution.

[0006] This utility model is achieved through the following technical solution: A floor heating water temperature and flow rate control device is applied to a wall-mounted fireplace. The outlet and return ends of the wall-mounted fireplace are each connected to a water distribution device. The device is characterized in that a floor heating pipe is connected to one side of the water distribution device at the outlet end, and the floor heating pipe is connected to the water distribution device at the outlet end. A first temperature sensor is installed between the water distribution device at the outlet end and the floor heating pipe, and a second temperature sensor is installed between the water distribution device at the outlet end and the floor heating pipe. The device also includes a controller, which is electrically connected to the wall-mounted fireplace, the water distribution device, the first temperature sensor, and the second temperature sensor. The controller controls the water distribution device to change the water flow rate entering the floor heating pipe, thereby causing a corresponding change in the temperature of the floor heating pipe.

[0007] A further technical solution includes a water distribution and collection device comprising a manual valve, a water pump connected to one side of the manual valve, an electromagnetic flow meter connected to one side of the water pump, a liquid distribution and collection valve connected to one side of the electromagnetic flow meter, and a controller electrically connected to the water pump and the electromagnetic flow meter.

[0008] In a further technical solution, the manifold valve includes a valve body, with multiple side pipes connected around the valve body. An inner cavity is provided inside the valve body, and the electromagnetic flowmeter is connected to the inner cavity. A valve piston is slidably disposed inside the inner cavity, and a power component is provided at the bottom of the valve body to drive the valve piston to move up and down.

[0009] In a further technical solution, the top of the valve piston is provided with a chamfer.

[0010] A further technical solution includes a power assembly comprising a housing fixedly disposed on the lower side of the valve body, a driven gear rotatably disposed within the housing, a threaded shaft internally threadedly connected to the driven gear, the threaded shaft being fixedly connected to the bottom of the valve piston, a plurality of guide rods fixedly disposed at the bottom of the valve piston, the guide rods slidingly passing through the housing, and a transmission structure for driving the driven gear to rotate being disposed within the housing.

[0011] In a further technical solution, the housing is connected and fixed to the valve body.

[0012] In a further technical solution, a heat dissipation box is fixedly installed on the lower side of the housing, and heat dissipation holes are provided inside the heat dissipation box.

[0013] A further technical solution includes a transmission structure comprising a motor fixedly mounted on the lower side of the housing, wherein a drive gear is fixedly mounted on the outer surface of the output shaft of the motor, and the drive gear meshes with the driven gear.

[0014] The beneficial effects of this utility model are as follows: First, when the device regulates water temperature and flow rate, it reads the water temperature at the inlet and outlet of the underfloor heating pipe through the first and second temperature sensors. Then, the electromagnetic flow meter is used to read the flow rate of the manifold. The controller coordinates the control of the water pump, the manifold valve, and the wall-mounted fireplace to adjust the flow rate and temperature of the pipeline, thereby indirectly regulating the water temperature in the underfloor heating pipe while regulating the flow rate.

[0015] II. Through the coordinated operation of the controller, wall-mounted fireplace, water pump, electromagnetic flow meter, manifold valve, first temperature sensor, and second temperature sensor, the following functions are achieved: The valve piston adjusts the opening of the side pipe, thereby reducing the flow rate of liquid entering the underfloor heating pipe and reducing the total heat of the water in the underfloor heating pipe, thus gradually lowering the room temperature. Furthermore, the water pump can slow down its operating speed, further reducing the flow rate of liquid in the pipe, which in turn accelerates the rate at which the room temperature decreases.

[0016] During the heating process, by increasing the opening of the side pipe, the controller controls the water pump to work faster, allowing the water to quickly enter the underfloor heating pipes for heat exchange and then return to the wall-mounted fireplace for reheating. Through this process, the room temperature rises more quickly.

[0017] Third, regarding the valve piston and chamfer, during liquid distribution, the chamfer is located on one side of the side pipe, which facilitates the guidance of the liquid and allows for a more even distribution of the liquid onto the four side pipes. Attached Figure Description

Detailed Implementation

[0024] like Figures 1-4 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1The projection relationships are consistent in all directions (up, down, left, right, front, back). This utility model discloses a floor heating water temperature and flow control device applied to a wall-mounted fireplace. The outlet and return ends of the wall-mounted fireplace are respectively connected to a manifold device that combines liquid distribution and flow regulation functions. A floor heating pipe is connected to one side of the manifold device at the outlet end, and the floor heating pipe is connected to the manifold device at the outlet end. A first temperature sensor is installed between the manifold device at the outlet end and the floor heating pipe, and a second temperature sensor is installed between the manifold device at the outlet end and the floor heating pipe. The device also includes a controller, which is connected to the wall-mounted fireplace, the manifold device, and the first temperature sensor. The first and second temperature sensors are electrically connected. The temperature at both ends of the underfloor heating pipes is read through the first and second temperature sensors. The controller controls the manifold to change the flow rate of water entering the underfloor heating pipes, thereby changing the temperature of the underfloor heating pipes accordingly. That is, a small inflow rate lowers the temperature of the underfloor heating pipes while keeping the water temperature constant, and a large inflow rate increases the temperature of the underfloor heating pipes while keeping the water temperature constant. The controller can also control the wall-mounted fireplace to change the water temperature by controlling the start and stop of its heating unit. Working together with the manifold, the controller realizes the function of regulating the water temperature and flow rate of the underfloor heating system.

[0025] Advantageously, the water distribution device includes a manual valve 11, a water pump 12 connected to one side of the manual valve 11, an electromagnetic flow meter 13 connected to one side of the water pump 12, and a liquid distribution valve 14 connected to one side of the electromagnetic flow meter 13. The controller is electrically connected to the water pump 12 and the electromagnetic flow meter 13. The water pump 12 pumps the water, and the electromagnetic flow meter 13 reads the flow data in the water distribution device and feeds it back to the controller so that the controller can control the flow rate of the liquid distribution valve 14.

[0026] Advantageously, for the water distribution device at the inlet end, the water pump 12 pumps water from the manual valve 11 to the electromagnetic flow meter 13, and for the water distribution device at the outlet end, the water pump 12 pumps water from the electromagnetic flow meter 13 to the manual valve 11.

[0027] Advantageously, the manifold valve 14 includes a valve body 31, with multiple side pipes 15 arranged around the valve body 31. The side pipes 15 are used to connect with the underfloor heating pipes, a first temperature sensor, or a second temperature sensor, and are connected by flanges and fasteners. The valve body 31 has an inner cavity 21. The top of the valve body 31 is fixedly connected to the electromagnetic flowmeter 13 through a flange, and the electromagnetic flowmeter 13 is connected to the inner cavity 21. A valve piston 23 is slidably arranged in the inner cavity 21, and a power assembly for driving the valve piston 23 to move up and down is provided at the bottom of the valve body 31.

[0028] Advantageously, the valve piston 23 is provided with a chamfer 22 at the top. When the chamfer 22 moves to the lower side of the part where the side pipe 15 communicates with the inner cavity 21, the chamfer 22 is used to divert or collect the water flow.

[0029] Advantageously, the power assembly includes a housing 16 fixedly disposed on the lower side of the valve body 31, a driven gear 29 rotatably disposed within the housing 16, a threaded shaft 25 threadedly connected within the driven gear 29, the threaded shaft 25 being fixedly connected to the bottom of the valve piston 23, a plurality of guide rods 24 fixedly disposed at the bottom of the valve piston 23, the guide rods 24 slidingly passing through the housing 16, and a transmission structure for driving the driven gear 29 to rotate being disposed within the housing 16.

[0030] Advantageously, the housing 16 is connected and fixed to the valve body 31 by fasteners.

[0031] Advantageously, a heat dissipation box 17 is fixedly installed on the lower side of the housing 16 by fasteners, and heat dissipation holes are provided inside the heat dissipation box 17.

[0032] Advantageously, the transmission structure includes a motor 26 fixedly disposed on the lower side of the housing 16, the output shaft of the motor 26 extending out of the housing 16, and a drive gear 27 fixedly disposed on the outer surface of the output shaft of the motor 26, the drive gear 27 meshing with the driven gear 29.

[0033] Advantageously, the guide rod 24 is disposed around the driven gear 29, and when the driving gear 27 meshes with the driven gear 29, the guide rod 24 is disposed on both sides of the driven gear 29 and the driving gear 27 and does not interfere with them.

[0034] When the controller controls the water distribution device, the electromagnetic flowmeter 13 reads the water flow rate in the water distribution device, and then controls the distribution valve 14 to change the water flow rate in the side pipe 15 after the distribution valve 14 is working. The water pump 12 is used to pump the liquid to improve the efficiency of liquid flow.

[0035] When the manifold valve 14 is in operation, the motor 26 drives the drive gear 27 to rotate, which in turn drives the driven gear 29 to rotate. Since the threaded shaft 25 is threadedly connected to the driven gear 29, and the guide rod 24 slides through the housing 16, the valve piston 23 can move up and down within the inner cavity 21. The chamfer 22 and the valve piston 23 can be used to completely close the side pipe 15 or the top of the inner cavity 21, or partially close the side pipe 15, or completely open the side pipe 15, thereby changing the opening degree of the side pipe 15 that guides the water. When the water pump 12 maintains a constant liquid delivery speed, the flow rate will also change due to the change in the opening degree of the side pipe 15.

[0036] When the manifold valve 14 distributes water, the liquid enters the inner cavity 21 from the top of the valve body 31, and then is distributed from the side pipe 15 to the first temperature sensor and the floor heating pipe.

[0037] When the manifold valve 14 collects water, the liquid flowing back from the underfloor heating pipe enters the inner cavity 21 through the side pipe 15 and gathers, and then continues to be guided upward from the valve body 31.

[0038] When regulating water temperature and flow rate, the device reads the water temperature at the inlet and outlet of the underfloor heating pipes through the first and second temperature sensors. Then, the electromagnetic flow meter 13 reads the flow rate of the manifold. The controller adjusts the flow rate and temperature of the pipeline by coordinating the control of the water pump 12, the manifold valve 14, and the wall-mounted fireplace.

[0039] The valve piston 23 adjusts the opening of the side pipe 15, thereby reducing the flow rate of liquid entering the underfloor heating pipe and the total heat of the water in the underfloor heating pipe, which in turn reduces the room temperature. Furthermore, the operating speed of the water pump 12 can be slowed down, further reducing the flow rate of liquid in the pipe, which in turn accelerates the rate at which the room temperature drops.

[0040] During the heating process, by increasing the opening of the side pipe 15, the controller controls the water pump 12 to operate faster, and the water quickly enters the underfloor heating pipes for heat exchange and returns to the wall-mounted fireplace for reheating. Through this process, the room temperature rises faster.

[0041] During this process, the electromagnetic flowmeter 13 continuously reads the flow data and sends it back to the controller to identify whether the flow regulation is successful.

[0042] For wall-mounted fireplaces, the controller can control their start and stop operation. When the heating part of the wall-mounted fireplace stops working, the returned liquid will not be reheated, but will be sent back into circulation to further cool the pipes, enabling faster cooling of the pipe temperature. During this process, the controller can also control the water pump 12 to accelerate its operation to achieve rapid circulation of the low-temperature liquid.

[0043] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
