Description

Technical Field

[0001] This utility model belongs to the field of electric heating water technology, specifically an electric heating water device with a preheating module. Background Technology

[0002] In modern industrial production processes, electrically heated hot water devices are widely used in many fields such as chemical engineering, food processing, textile printing and dyeing, and pharmaceuticals. Whether it is temperature control in chemical reactions, raw material cleaning and sterilization in food processing, dyeing and finishing processes in textile printing and dyeing, or equipment cleaning and material handling in pharmaceutical processes, a stable supply of hot water that meets specific temperature requirements is essential.

[0003] Currently, traditional electric water heating devices typically use a direct heating method for cold water. This means that after cold water enters the device, the electric heating element directly heats it to the required temperature. This heating method has many drawbacks. On the one hand, because the initial temperature of the cold water is low, the electric heating element needs to consume a large amount of electricity to raise the water temperature to the operating temperature in a short time, resulting in high energy consumption and increased operating costs. This represents a significant expense for industrial enterprises with large-scale continuous production.

[0004] On the other hand, directly heating cold water results in a long heating time, which cannot quickly meet the immediate demand for hot water during production, thus reducing production efficiency. Furthermore, frequent high-power heating shortens the lifespan of electric heating elements, increases equipment maintenance costs and downtime for repairs, and seriously disrupts the normal production order of enterprises.

[0005] Therefore, an electric heating water device with a preheating module is proposed to address the above problems. Utility Model Content

[0028] 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.

[0029] like Figures 1 to 6 As shown, this utility model provides an electric heating water device with a preheating module, including a protective box 1;

[0030] The protective box 1 is equipped with a preheating heating assembly 2. The preheating heating assembly 2 includes an outer preheating pipe assembly 21 installed inside the protective box 1, three support boxes 22 installed on the side of the protective box 1, a main heating pipe assembly 23, a connecting pipe 24, an interface pipe 25, a water outlet pipe 26, an electromagnetic heating module 27, and a preheating module 28 for heating.

[0031] The main heating tube assembly 23 is installed inside the support box 22, and a water outlet pipe 26 is installed at the outlet of the main heating tube assembly 23. The water outlet pipe 26 passes through one of the support boxes 22 and extends to the outside of the support box 22. The water inlet end of the outer preheating tube assembly 21 passes through the protective box 1 and extends to the outside of the protective box 1. The connecting pipe 24 is installed at one end of the outer preheating tube assembly 21. The interface pipe 25 is installed at the water inlet end of the main heating tube assembly 23, and one end of the interface pipe 25 passes through the support box 22 and extends into the inside of the protective box 1, and is connected to the connecting pipe 24.

[0032] The electromagnetic heating module 27 is installed on the upper surface of the three support boxes 22, and the preheating module 28 is installed on the upper surface of the protective box 1.

[0033] The support box 22 and the protective box 1 are detachable. The outer preheating tube group 21 and the main heating tube group 23 form a "preheating + main heating" dual-stage heating, thereby reducing the energy consumption of the main heating module, improving the overall thermal efficiency, and preheating the cold water.

[0034] Both the electromagnetic heating module 27 and the preheating module 28 adopt electromagnetic heating. They contain an anti-dry burning and start-stop system. They heat through the principle of electromagnetic induction, which further improves thermal efficiency, heating speed and temperature uniformity.

[0035] The main heating tube group 23 consists of three interconnected coils. The coil structure can extend the water flow path, increase the heating contact time, and improve the heat exchange efficiency. The three coils correspond one-to-one with the three support boxes 22.

[0036] The surface of the connecting pipe 24 is equipped with a detachable assembly 3, which includes a detachable assembly pipe 31 installed at the connecting end of the connecting pipe 24, a stabilizing pipe 32 installed at the connecting end of the interface pipe 25, and a sleeve rod 33 and a detachable assembly rod 34 for detachment.

[0037] The stabilizing tube 32 is inserted into the inside of the disassembly tube 31. The sleeve rod 33 is installed on the surface of the disassembly tube 31. The disassembly rod 34 is slidably connected inside the sleeve rod 33. One end of the disassembly rod 34 passes through the sleeve rod 33 and the disassembly tube 31 and is inserted into the insertion hole opened on the surface of the stabilizing tube 32. The other end of the disassembly rod 34 passes through the sleeve rod 33 and extends to the top of the sleeve rod 33. The pipeline is connected by insertion. Connection or disassembly can be completed by one hand, which greatly saves installation time and makes it convenient for operators to disassemble and repair.

[0038] A limiting plate 35 is installed on the surface of the disassembly rod 34. The limiting plate 35 is slidably connected inside the sleeve rod 33, which can limit the movement position of the disassembly rod 34 and prevent the disassembly rod 34 from shifting position during movement.

[0039] A reset spring 36 is fitted on the surface of the disassembly rod 34. One end of the reset spring 36 is connected to the limiting plate 35, and the other end of the reset spring 36 is installed inside the sleeve rod 33. After the disassembly rod 34 is released, the reset spring 36 pushes the disassembly rod 34 to automatically insert into the insertion hole of the stabilizing tube 32 without manual fixing, thus improving the convenience of operation.

[0040] The structures of the electromagnetic heating module 27 and the preheating module 28 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagrams of the electromagnetic heating module 27 and the preheating module 28 in this utility model are common knowledge in the field, and their working principles are already known technologies. The appropriate model should be selected based on actual use.

[0041] Working principle and process: Cold water flows from the inlet end of the outer preheating tube group 21. Then, the preheating module 28 is activated. The preheating module 28 heats the outer preheating tube group 21 inside the protective box 1, and the cold water is initially heated in the tube.

[0042] Since the disassembly pipe 31 is connected to the stabilizing pipe 32, the preheated water flows into the interface pipe 25 through the connecting pipe 24 and enters the water inlet of the main heating pipe group 23. At this time, the preheated water enters the main heating pipe group 23, and then the electromagnetic heating module 27 is activated to heat the main heating pipe group 23, so that the water temperature is further increased to the target temperature. Since the main heating pipe group 23 is composed of three interconnected coils, the water flow residence time is increased, the heating time is increased, and the heating effect of the water is further improved.

[0043] The anti-dry-burning system inside the electromagnetic heating module 27 and the preheating module 28 monitors the water level in real time. If the water level is insufficient, it will automatically cut off the power. The start-stop system will automatically adjust the heating power or stop heating according to the set temperature to avoid energy waste.

[0044] The heated water flows out from the outlet of the main heating tube assembly 23 through the outlet pipe 26 for user use;

[0045] When pipeline maintenance is required, first open the protective box 1 and the support box 22. Then, pull the disassembly rod 34 upward, which will cause the limit plate 35 to stretch the return spring 36, so that the disassembly rod 34 is disengaged from the insertion hole of the stabilizing tube 32. This will separate the disassembly tube 31 and the stabilizing tube 32, and disconnect the connecting tube 24 and the interface tube 25. After maintenance is completed, insert the stabilizing tube 32 into the disassembly tube 31, release the disassembly rod 34, and the return spring 36 will push the limit plate 35 and the disassembly rod 34 to reset, so that the disassembly rod 34 is inserted into the insertion hole of the stabilizing tube 32, thus completing the quick fixation.

[0046] The support box 22 and the protective box 1 are detachable structures connected by bolts and threads, which allows the outer preheating tube group 21 and the main heating tube group 23 to be separated and inspected after the disassembly tube 31 and the stabilizing tube 32 are separated. Both the support box 22 and the protective box 1 are openable boxes, which are mature existing technologies. For details, please refer to the existing technologies.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
