Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to an environmentally friendly and energy-saving heat circulation heating equipment. Background Technology

[0002] Heating equipment refers to various devices used to provide heat to meet people's temperature needs in daily life, production, and other processes. For example, wall-mounted boilers heat water in the furnace by burning fuel, and then transport the hot water to radiators or underfloor heating pipes through a circulation system to provide heat to the room.

[0003] However, existing technologies still have the following problems:

[0004] First, most of the existing environmentally friendly and energy-saving heat circulation heating equipment has insufficient heat exchange efficiency and the heat exchange process is not sufficient. Most simple tubular heat exchangers have short flow paths and limited contact areas between cold and hot water, resulting in insufficient heat transfer and inability to effectively utilize the heat of hot water to preheat cold water, thus making energy inefficient.

[0005] Secondly, existing environmentally friendly and energy-saving heating equipment is usually not convenient for hot water circulation. Every time hot water is used, a large amount of cold water needs to be reheated. Some small instant water heaters directly heat cold water when users use hot water. After use, the remaining hot water cannot participate in circulation, and the cold water needs to be reheated again for the next use, consuming a lot of energy.

[0006] To address the aforementioned problems, the inventors propose an environmentally friendly and energy-saving heat circulation heating device. Utility Model Content

[0007] In order to solve the problems of insufficient heat exchange efficiency and inconvenience in hot water circulation in environmentally friendly and energy-saving heating equipment, the purpose of this utility model is to provide an environmentally friendly and energy-saving heat circulation heating equipment.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an environmentally friendly and energy-saving heat circulation heating device, including a base plate, a hot water tank and a hot water container fixedly mounted on the upper surface of the base plate, a heater fixedly mounted on the upper surface of the base plate, and the upper surface of the heater movably fitting against the hot water tank, an inlet pipe and an outlet pipe fixedly mounted on one side of the outer surface of the hot water tank, a spiral pipe connected to the inner end of the outlet pipe, an input pipe connected to one end of the spiral pipe, a water pump mounted on the outer surface of the input pipe, and the lower surface of the water pump fixedly connected to the base plate, one end of the input pipe penetrating the hot water container and fixedly mounted with a heat transfer curved pipe, one end of the heat transfer curved pipe penetrating the hot water container and fixedly mounted with an outlet pipe, one end of the outlet pipe penetrating the hot water container and fixedly mounted with a connecting pipe, and one end of the connecting pipe connected to the outlet pipe.

[0009] Preferably, a water supply pipe and a return pipe are symmetrically connected between the hot water tank and the hot water container, and an electromagnetic valve is provided on the outer surface of the return pipe, with the lower surface of the electromagnetic valve fixedly connected to the base plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model utilizes the residual heat of the hot water tank to initially heat cold water in the spiral tube, and then further heats it in the hot water tank. This tiered heat utilization method improves energy efficiency, reduces energy waste, lowers overall heating energy consumption, and meets the requirements of environmental protection and energy conservation.

[0012] 2. This utility model uses a circulation design between the hot water tank and the hot water container to allow water to circulate and heat continuously within the system, avoiding the high energy consumption required for frequently heating large amounts of cold water, making full use of the existing heat in the system, and effectively saving energy costs.

[0018] 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.

[0019] Example: Figure 1-3 As shown, this utility model provides an environmentally friendly and energy-saving heat circulation heating device, including a base plate 1. A hot water tank 2 and a hot water reservoir 3 are fixedly mounted on the upper surface of the base plate 1. A heater 21 is fixedly mounted on the upper surface of the base plate 1, and the upper surface of the heater 21 is movably fitted to the hot water tank 2. The heater 21 is an electric heating rod type heater, evenly distributed at the bottom of the hot water tank 2, and is tightly fitted to the hot water tank 2 by thermally conductive silicone to improve heat transfer efficiency. The heater 21 is wrapped with a layer of heat insulation material to reduce heat loss to the surrounding environment. A water inlet pipe 22 and a water outlet pipe 28 are fixedly mounted on one side of the outer surface of the hot water tank 2. The inner end of the water outlet pipe 28 is connected to a spiral pipe 2. 3. The spiral tube 23 is made of copper. This design increases the flow path and time of water in the hot water tank 2, allowing for full absorption of heat from the hot water tank 2. The hot water tank 2 and the hot water container 3 are pre-filled with hot water, providing a basic heat reserve for subsequent heat circulation and heating processes. The heater 21 can heat the water in the hot water tank 2, providing a heat source. Cold water flows into the spiral tube 23 from the inlet pipe 22. Since the spiral tube 23 is located inside the hot water tank 2, the hot water in the hot water tank 2 will preliminarily heat the cold water in the spiral tube 23. This utilizes the principle of heat conduction, where heat is transferred from the hot water in the hot water tank 2 to the cold water in the spiral tube 23, causing the cold water temperature to rise.

[0020] One end of the spiral tube 23 is connected to an input pipe 24. A water pump 29, a centrifugal pump, is mounted on the outer surface of the input pipe 24, and its lower surface is fixedly connected to the base plate 1. One end of the input pipe 24 passes through the hot water tank 3 and is fixedly mounted with a heat transfer curved tube 25. The heat transfer curved tube 25 is also made of copper and is arranged in a serpentine pattern inside the hot water tank 3 to increase the contact area with the water and improve heat exchange efficiency. The surface of the heat transfer curved tube 25 is silver-plated to further improve heat conduction performance. One end of the heat transfer curved tube 25 passes through the hot water tank 3 and is fixedly mounted with an output pipe 26. One end of the output pipe 26 passes through the hot water tank 2 and is fixedly mounted with a connecting pipe 27. One end of the connecting pipe 27 is connected to the outlet pipe 28. When connected, the water pump 29 starts, providing power to draw the pre-heated water from the spiral tube 23 and deliver it to the hot water tank 3 through the input pipe 24. The presence of the water pump 29 ensures that the water can flow continuously and stably in the system, overcoming factors such as pipe resistance and achieving effective circulation. The water entering the hot water tank 3 flows into the heat transfer tube 25, which is immersed in the hot water in the hot water tank 3. During this process, the water in the heat transfer tube 25 and the hot water in the hot water tank 3 undergo further heat exchange, causing the water temperature to rise further. After heat exchange, the water flows from the other end of the heat transfer tube 25 into the hot water tank 2 through the output pipe 26, and finally through the connecting pipe 27 and the outlet pipe 28 to be discharged, resulting in heated warm water.

[0021] The spiral tube 23 and connecting tube 27 are rationally arranged inside the hot water tank 2. This structural design increases the water flow path and contact area with hot water within a limited space, improving heat exchange efficiency. At the same time, the entire equipment structure is more compact, reducing the floor space occupied.

[0022] A water exchange pipe 34 is connected to the upper surface of the hot water tank 3, and a pipe cover 35 is fitted onto the upper surface of the water exchange pipe 34. A drain pipe 36 is connected to one side of the hot water tank 3, and a valve handle is fixed on the upper side of the outer surface of the drain pipe 36. The drain pipe 36 on the hot water tank 3 is used to discharge the heated hot water for the user. The user controls the drain switch and flow rate by operating the valve handle. When it is necessary to change the water level in the hot water tank 3, the pipe cover 35 on the water exchange pipe 34 can be opened to replenish cold water into the hot water tank 3 through the water exchange pipe 34.

[0023] A water supply pipe 31 and a return pipe 32 are symmetrically connected between the hot water tank 2 and the hot water reservoir 3. The outer surface of the return pipe 32 is equipped with a solenoid valve 33, and the lower surface of the solenoid valve 33 is fixedly connected to the base plate 1. The hot water tank 2 and the hot water reservoir 3 are connected by the water supply pipe 31 and the return pipe 32 to form a large circulation. A temperature measuring structure can be installed on the hot water reservoir 3. When the water temperature in the hot water reservoir 3 reaches a certain condition, the solenoid valve 33 opens, and the heated water in the hot water reservoir 3 flows back to the hot water tank 2 through the return pipe 32 for reheating. Meanwhile, the hot water in the hot water tank 2 is replenished to the hot water reservoir 3 through the water supply pipe 31. This continuous circulation provides hot water to the user.

[0024] Working principle: Hot water tank 2 and hot water tank 3 are pre-filled with hot water to provide basic heat reserves for subsequent heat circulation and heating process. Heater 21 can heat the water in hot water tank 2 to provide heat source. Cold water flows into spiral tube 23 from water inlet pipe 22. Since spiral tube 23 is located inside hot water tank 2, the hot water in hot water tank 2 will preliminarily heat the cold water in spiral tube 23. This utilizes the principle of heat conduction. Heat is transferred from the hot water in hot water tank 2 to the cold water in spiral tube 23, causing the cold water temperature to rise.

[0025] The water pump 29 starts, providing power to draw the pre-heated water out of the spiral tube 23 and deliver it to the hot water tank 3 through the input pipe 24. The presence of the water pump 29 ensures that the water can flow continuously and stably in the system, overcomes factors such as pipe resistance, and achieves effective circulation. The water entering the hot water tank 3 flows into the heat transfer tube 25, which is immersed in the hot water in the hot water tank 3. During this process, the water in the heat transfer tube 25 and the hot water in the hot water tank 3 undergo further heat exchange, which further increases the water temperature. After heat exchange, the water flows from the other end of the heat transfer tube 25 into the hot water tank 2 through the output pipe 26, and finally through the connecting pipe 27 and the outlet pipe 28 to be discharged, resulting in heated warm water.

[0026] Hot water tank 2 and hot water reservoir 3 are connected by water supply pipe 31 and return pipe 32 to form a large circulation. A temperature measuring structure can be installed on hot water reservoir 3. When the water temperature in hot water reservoir 3 reaches a certain condition, the solenoid valve 33 opens. The heated water in hot water reservoir 3 flows back to hot water tank 2 through return pipe 32 for reheating. Meanwhile, the hot water in hot water tank 2 is replenished to hot water reservoir 3 through water supply pipe 31. This continuous circulation provides hot water to users.

[0027] The drain pipe 36 on the hot water tank 3 is used to discharge the heated hot water for the user. The user controls the drain switch and flow rate by operating the valve handle. When it is necessary to change the water level in the hot water tank 3, the pipe cover 35 on the water replacement pipe 34 can be opened to replenish cold water into the hot water tank 3 through the water replacement pipe 34.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
