Embodiment 1

[0033] Refer to attached figure 1 And attached figure 2 or attached image 3 or attached Figure 4. For electronic water heaters, the mains power is controlled by a water pressure switch, and the 300V DC is rectified by the bridge stack to form a circuit through the heating coil and IGBT. Under the control of the PWM switching pulse, the IGBT works with the heating coil and the vibration capacitor connected in parallel, and generates high-frequency alternating current in the heating coil. The bottom of the plate heat exchange box, which is relatively close to the insulating assembly of the disc heating coil, generates a strong eddy current and heats up rapidly, and the electromagnetic energy in the heating coil is converted into heat energy. The water flowing through the bottom plate groove of the heat exchange box fully exchanges heat with the bottom plate due to the length of the groove, and flows out after the water temperature rises, realizing the purpose of electroni...

Embodiment 2

[0035] Change the box cover into a plastic thin plate and install the inlet and outlet water pipe interfaces and assemble it with the ferromagnetic box body to form a plate heat exchange box. Then the box is insulated from the heating coil of the electronic frequency converter and tightly assembled together. Place the circuit board on the front and bottom of the heat exchange box, pay attention to the ventilation and heat dissipation of the circuit board, IGBT and heating coil, and the buttons and display screen are in front of the circuit board. The heating coil and heat exchange box are on the upper part of the electric water heater.

Abstract

The invention relates to an electronic water heater, which comprises an power electronic frequency conversion magnetic inductive loop heating and plate type thermal interchange box. The invention realizes high thermal efficiency, easy production and low cost.

Description

Technical field: [0001] The invention relates to an electric water heater. Specifically, it is an electronic frequency conversion magnetic induction tankless water heater. Background technique: [0002] Traditional electric water heaters heat water by resistance heating. Due to the large heat loss caused by the thermal resistance of the insulating material of its heating element, the power consumption is high and the thermal efficiency is low. In order to solve the contradiction between power and time during heating, the heat storage method of water tank is adopted. However, there are problems such as fixed water storage but large changes in water consumption, heat dissipation loss, and bulky equipment, and problems such as scale and leakage have also plagued us for a long time. [0003] The improved electric water heater is electromagnetic induction type. Although the loss caused by the thermal resistance of the insulator of the resistance heating body is solved, most o...
