Description

Multi-layer water pipe induction water heater

technical field

The utility model relates to the technical field of electric water heaters, in particular to a multi-layer water pipe inductance water heater.

Background technique

As a household necessity, water heaters are widely used in daily life. Most of the original water heaters use coal and gas as fuel, and the exhaust gas causes environmental pollution, and the thermal efficiency is not high. With the reduction of finite energy and the sharp increase in price, electric water heaters are gradually becoming more and more important products after ordinary household gas water heaters due to their simple operation, energy saving and environmental protection.

As the competition of water heater products in the market continues to intensify, more and more attention is paid to its technical performance and economic performance in the promotion process of products. Electric water heaters on the market are mostly electric resistance water heaters. The principle is to immerse high-impedance electric heating elements in water, and the electric heating elements will generate heat to work. However, this kind of water heater does not realize the real separation of water and electricity, and there is a danger of electric leakage, and the luminescence after resistance heating reduces thermal efficiency and wastes energy. In addition, there is also an inductive water heater on the market, but there is only one central tank, which has the disadvantages of small heating area and insufficient use of magnetic lines of force.

Contents of the invention

In order to overcome the disadvantages of the above-mentioned prior art, the utility model discloses a multi-layer water pipe induction water heater.

A multi-layer water pipe inductive water heater mainly includes an electromagnetic induction generator, an electromagnetic coil, an insulating layer, a central water tank, a water pipe, a tube plate, a pipe box, an electromagnetic shield, an insulation layer and a controller, and is characterized in that: the central water The outer wall of the tank is seamlessly wrapped with an insulating layer. The electromagnetic coil is evenly wound around the insulating layer, and the electromagnetic coil is wrapped with an insulating layer. Several water pipes are arranged along the circumference close to the outer wall of the insulating layer. The water pipe penetrates into the tube plates at both ends and is fixed by welding. The electromagnetic coil passes through the electromagnetic shielding cover and the insulation layer to connect the electromagnetic induction generator. The electromagnetic coil is a high-temperature mica wire, and the winding method is multi-strand winding.

The combination of the water pipe and the insulating layer is generally a 2-layer combination or a 3-layer combination.

Both the water pipe and the central water tank are made of stainless steel, the outer diameter of the water pipe is 30-35mm, and the outer diameter of the central water tank is 60-70mm.

The AC frequency of the electromagnetic induction generator and the internal temperature of the water heater are regulated by a controller.

The beneficial effects of the utility model are as follows: firstly, the circularly arranged water pipes cleverly utilize the proximity effect and the skin effect of alternating current to improve thermal efficiency and avoid uneven heating; The external magnetic field generated by the electromagnetic coil is fully utilized to improve the heating efficiency; the third is the use of induction heating, which realizes the separation of water and electricity in the true sense, improves the safety of the equipment, and has no worries about leakage.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The assembly process of the multi-layer water tube inductance water heater: firstly, the central water bladder penetrates the tube plates at both ends and is welded and fixed. The central water tank is located at the center of the tube plates at both ends; Winding on the outside of the insulation layer, the electromagnetic coil is wrapped with the insulation layer, and the outside of the insulation layer is uniformly arranged with water pipes along the circumference, and the two ends of the water pipes pass through the tube plate and are welded and fixed. The water pipe is wrapped with electromagnetic shielding cover and insulation layer in turn, and the electromagnetic coil wound inside passes through the electromagnetic shielding cover and insulation layer to connect with the external electromagnetic induction generator, and the tube boxes at both ends are connected to the tube plates at both ends by welding.

When the equipment is running, water enters the tube box through the water inlet pipe, and the tube box distributes the water to several water pipes and the central tank. When the external control power supply is connected, the electromagnetic induction generator generates high-speed alternating current, and the alternating current passes through the electromagnetic coil to generate a high-speed magnetic field, which heats the water in the central water tank and the water pipe. According to the temperature displayed by the controller, the frequency of the alternating current can be adjusted and the heating temperature can be controlled to obtain the required hot water.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
