Description

Technical Field

[0001] This utility model relates to the field of heater technology, and more specifically, to a uniform heating structure for the heat exchange chamber of a floor heating machine. Background Technology

[0002] A water heater is a device that uses various physical principles to raise the temperature of cold water to hot water within a certain time. Based on different principles, they can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic water heaters, air source water heaters, and central heating water heaters, etc.

[0003] A search revealed an existing patent (publication number: CN211204410U) that discloses a heater with an explosion-proof tube function, comprising a first housing, a second housing, a heating resistance wire, and a heating tube. The second housing is located on one side of the first housing. Both the first and second housings are made of aluminum. The heating tube is housed within the first housing. The heating resistance wire, by employing a coiled arrangement, increases the contact area with the water inside the second housing, thereby improving the preheating efficiency of the water. A energizing wire is fixedly connected to a first wire connector, energizing the heating tube and further heating the water entering the first housing. Preheating the water through the heating resistance wire prevents the heating tube wall from cracking or bursting due to thermal expansion and contraction under alternating hot and cold conditions. The coiled arrangement of the heating tube increases the contact area with the water inside the first housing, thus improving the heating efficiency. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing heaters are problematic because when the underfloor heating system is operating normally, hot water circulates in the pipes, and heat is evenly distributed into the room through the floor. If a large amount of cold water is suddenly added, the cold water will absorb the heat from the surrounding hot water, causing the water temperature to drop rapidly. The heat dissipation rate of the underfloor heating system will slow down significantly when the water temperature drops, because the driving force of heat transfer is temperature difference. The drop in water temperature reduces the temperature difference between the water and the room, thus affecting heating efficiency. When the water circulates in the underfloor heating system, impurities and sediments will gradually accumulate. Mud, rust, and other substances in the water will make the water turbid and may even affect the equipment, thus hindering the transfer of heat to the water and reducing the heat transfer efficiency of the entire heating system.

[0005] Therefore, a uniform heating structure for the heat exchange chamber of a floor heating system is proposed to address the above problems. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] As attached Figures 1 to 4The diagram shows a uniform heating structure for a floor heating unit's heat exchange chamber, comprising a heating chamber 1 and a preheating and water replenishment mechanism 11. A control panel 2 is installed at the upper end of the heating chamber 1. A first heating coil 3 is installed inside the heating chamber 1. An infrared liquid level sensor 31 is installed on the right side of the first heating coil 3. A first power interface 4 is provided at the upper end of the right side of the heating chamber 1. A water outlet 5 is provided below the first power interface 4. A water return outlet 6 is provided below the water outlet 5. A turbidity sensor 7 is installed on the left side of the inner wall of the heating chamber 1. A water replenishment outlet 8 is provided at the upper end of the left side of the heating chamber 1. A drain pipe 9 is provided at the lower end of the left side of the heating chamber 1. A first valve 10 is embedded in the drain pipe 9.

[0024] The preheating and water replenishment mechanism 11 is located on one side of the heating chamber 1. A second heating coil 12 is installed on the left side of the inner cavity of the preheating and water replenishment mechanism 11. A second power interface 121 is provided on the top of the second heating coil 12. A temperature sensor 122 is installed on the right side of the inner cavity of the preheating and water replenishment mechanism 11. A water inlet 13 is provided on the right side of the upper end of the second heating coil 12. A second valve 15 is provided above the water inlet 13. A water receiving pipe 14 is installed above the second valve 15. A drain outlet 16 is provided at the lower right end of the preheating and water replenishment mechanism 11. A water pump 17 is provided on the right side of the drain outlet 16. A water delivery pipe 18 is installed at the output end of the water pump 17.

[0025] When in use, the first heating coil 3 starts working after the first power interface 4 is powered on. The temperature sensor 122 monitors the water temperature in real time and feeds it back to the control system of the control panel 2. The control system adjusts the power of the first heating coil 3 according to the preset temperature parameters to preheat the water to a suitable temperature. The water in the heating tank 1 is discharged through the outlet 5 and the heating water is recycled through the return outlet 6. Thus, the heating tank 1 is connected to the external heating pipe to achieve circulating heating, effectively transferring heat to the places where it is needed. The infrared liquid level sensor 31 at the bottom of the heating tank 1 can monitor the liquid level in the heating tank 1 in real time and accurately. Once the liquid level is lower than the preset safety value, it will transmit a signal to the control panel 2. The control panel 2 will then start the preheating water replenishment mechanism 11 to replenish water. At the same time, it can also prevent the first heating coil 3 from being damaged by dry burning due to lack of water. The turbidity sensor 7 detects the turbidity of the heating water in the heating tank 1. When the water quality deteriorates and the turbidity exceeds the set value, the control panel 2 controls the first valve 10 to open in time to discharge the sewage. The automatic drainage function effectively removes impurities, sediments, and microorganisms from the water, keeping the water in the heating tank 1 clean. Simultaneously, the infrared liquid level sensor 31 monitors the water level, ensuring that the first valve 10 is closed after drainage, facilitating water replenishment by the preheating and replenishment mechanism 11. The second heating coil 12 preheats the replenished water in the preheating and replenishment mechanism 11. The preheated water entering the heating tank 1 prevents significant temperature fluctuations within the tank, helping to maintain a stable temperature throughout the heating system and effectively preventing room temperature fluctuations. The fluctuating internal temperature improves heating comfort. Temperature sensor 122 measures the water temperature in the preheating water supply mechanism 11 in real time and feeds the data back to control panel 2. Control panel 2 precisely controls the heating power of the second heating coil 12 according to the set temperature parameters to ensure that the water added to the heating tank 1 reaches the appropriate preheating temperature. Water pump 17 provides power for the water flow. During the water supply process, water pump 17 draws preheated water from the preheating water supply mechanism 11 through drain port 16 and stably delivers it to the heating tank 1 through water pipe 18. Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the first heating coil 3 is spiral in shape, and the first heating coil 3 is electrically connected to the first power interface 4. Furthermore, the spiral shape of the first heating coil 3 increases the contact area with water, so that when water flows through the coil, more water molecules can come into contact with the surface of the coil, and heat is transferred to the water more efficiently. The first power interface 4 is connected to an external power source to transmit current to the first heating coil 3 for heating.

[0028] In a preferred embodiment, the second heating coil 12 is arranged in a series of U-shaped rings, and the second heating coil 12 is electrically connected to the second power interface 121. Furthermore, the second power interface 121 is connected to an external power source to transmit current to the second heating coil 12 for heating. The arrangement of the second heating coil 12 in a series of U-shaped rings greatly increases the contact area between the heating coil and the water, allowing more water to fully contact the second heating coil 12, thus making heat transfer more efficient.

[0029] In a preferred embodiment, the end of the drain outlet 16 away from the preheating and water replenishment mechanism 11 is connected to the input end of the water pump 17, and the end of the water supply pipe 18 away from the water pump 17 is connected to the water replenishment port 8. Furthermore, the output end and input end of the water pump 17 are respectively connected to the water replenishment port 8 and the drain outlet 16, providing a strong and stable power for water circulation, and can actively transport the water in the preheating and water replenishment mechanism 11 to the heating box 1.

[0030] In a preferred embodiment, an exhaust valve 19 is provided on the left side of the control panel 2, and the two ends of the second valve 15 are respectively connected to the water inlet 13 and the water pipe 14; furthermore, the exhaust valve 19 can timely discharge the gas during heating to avoid excessive internal pressure.

[0031] In a preferred embodiment, the outlet 5 and the return outlet 6 have the same diameter, and the drain pipe 9 has a larger diameter than the outlet 5. Furthermore, the same diameter of the outlet 5 and the return outlet 6 can ensure a balance in the flow of water in and out. When hot water flows out from the outlet 5, passes through the external heating pipe, and then flows back from the return outlet 6, the same diameter can make the water circulation more stable. The larger diameter of the drain pipe 9 is conducive to the rapid discharge of sewage containing impurities. When the heating tank 1 needs to be drained, the larger diameter can make the sewage flow out more quickly under the action of gravity, reducing the drainage time.

[0032] The working process of this utility model is as follows: First, when the entire system starts running, the first power interface 4 is powered on, causing the spiral-shaped first heating coil 3 to start working and heat the water in the heating tank 1. The infrared liquid level sensor 31 monitors the water level in the heating tank 1 in real time. When the water level is lower than the set lower limit or when it is necessary to replace the water to avoid excessive turbidity, the infrared liquid level sensor 31 or the turbidity sensor 7 detects that the water level or the turbidity in the water is too high, and the signal is transmitted to the control panel 2. The control panel 2 starts the preheating and water replenishment mechanism 11, the second valve 15 is opened, and the external water source flows into the preheating and water replenishment mechanism 11 from the inlet 13 through the water inlet pipe 14. At the same time, the second power interface 121 is powered on, and several U-shaped second heating coils 12 are arranged in a circular pattern to preheat the incoming water. The temperature sensor 122 monitors the water temperature at all times and feeds the data back to the control panel 2. The control panel 2 adjusts the power of the second heating coil 12 according to the preset temperature parameters so that the water is preheated to a suitable temperature. After preheating is completed, the water pump... 17. Water is drawn from the preheating water replenishment mechanism 11 through the drain outlet 16 and transported to the heating chamber 1 through the water supply pipe 18 from the water replenishment port 8, completing the water replenishment operation and ensuring sufficient water volume in the heating chamber 1 for circulating heating. Simultaneously, during the heating process, the control panel 2 controls the opening of the first valve 10, allowing wastewater to be quickly discharged through the drain pipe 9. Due to the large diameter of the drain pipe 9, it effectively and quickly cleans impurities from the chamber. After discharge, the infrared liquid level sensor 31 detects that the water level is too low, and then... The indirect control valve 10 is closed, blocking the preheating water supply mechanism 11 to prevent water leakage and dry burning. After the water in the heating chamber 1 is heated to a certain temperature, it flows out from the outlet 5 and enters the external heating pipe. After releasing heat, it flows back into the heating chamber 1 through the return water port 6, forming a circulating heating system. Because the outlet 5 and the return water port 6 have the same diameter, the stability and balance of the circulating water flow are ensured, making the entire heating process uniform and efficient. The above is the working principle of the uniform heating structure of the heat exchange chamber of this type of floor heating machine.
