Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, and specifically to a heating device for a steam generator. Background Technology

[0002] A steam generator is a device that heats water to evaporate it into steam. It can be used in various applications requiring steam, such as steam ovens, steam mops, and steam cleaners. Existing electrically heated steam generators typically consist of a heat-conducting shell with a water inlet and a steam outlet. An electric heating element is located on one side of the shell. When electricity is applied to the heating element, the entire shell heats up. Water entering through the inlet absorbs heat and turns into steam, which is then discharged through the steam outlet. Because this type of steam generator only has one heating element, the heating speed is slow, and the steam production rate is also slow. Utility Model Content

[0006] Preferably, a one-way valve is installed at the upper end of the heater.

[0007] Preferably, a pressure relief valve is installed at the upper end of the heater.

[0008] Preferably, a pressure switch is installed at the upper end of the heater.

Detailed Implementation

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-6 As shown, a heating device for a steam generator includes a heater 1 and a heater 2 connected thereto. The heater 1 has an electric heating tube 3 installed inside it, and a water outlet 4 is opened at the upper or lower end of the heater 1. The heater 2 has an electric heating tube 5 and a gas-liquid channel 19 installed inside it. The water inlet of the gas-liquid channel 19 is connected to the water outlet 4. The bottom of the heater 1 has a mounting hole 6 for installing a temperature controller. The temperature controller detects the temperature of the liquid inside the heater in real time and controls it accordingly.

[0032] This invention, through the design of two heaters, enables the water inside the heater to be heated simultaneously through two electric heating tubes, thereby increasing the heating speed, generating steam quickly, reducing energy consumption, and greatly increasing efficiency.

[0033] The heater 1 is equipped with a one-way valve 7 at its upper end. When the internal pressure is negative to a certain value, the valve exhausts air inward.

[0034] The heater 1 is equipped with a pressure relief valve 8 at its upper end. When the internal pressure is too high, the valve releases pressure and exhausts air outward to keep the internal air pressure balanced.

[0035] A pressure switch 9 is installed at the upper end of the heater 1 to realize the detection, display, alarm and control signal output of the medium pressure signal.

[0036] The lower end face or side face of the heater-1 is formed with a mounting position-11 for mounting a temperature controller-10. The temperature controller-10 is used to control the switching of the electric heating tube-3 inside the heater-1.

[0037] The lower end face of the heater-1 is formed with a mounting base-13 for mounting fuse-12. When the temperature of the heater-1 is too high and exceeds the critical value of the fuse, the circuit of the heater-1 can be disconnected in time by the fuse-12, thereby improving safety.

[0038] The heater 2 has a mounting position 2 15 formed on its side for mounting a temperature controller 2 14. The temperature controller 2 14 is used to control the switching of the electric heating tube 2 5 inside the heater 2.

[0039] The gas-liquid channel 19 can be designed as a spiral stainless steel flat water pipe to achieve step-by-step heating water flow and improve the heating speed. The gas-liquid channel 19 can also be enclosed by a cover plate after a groove is dug inside the heater 2.

[0040] The heater 2 has a mounting base 2 17 formed on its side for mounting fuse 2 16. When the temperature of heater 2 is too high and exceeds the fuse's critical value, fuse 2 16 can disconnect the circuit of heater 2 in time, thus improving safety.

[0041] The second heater 2 is installed on the side of the first heater 1 or the second heater 2 is partially disposed in the inner cavity of the first heater 1 and integrally formed therewith.

[0042] The heater 1 is provided with a water inlet 18 at the top so that water can be injected into the heater 1 through the water inlet 18.

[0043] The cover plate 20 is provided with screw holes 21 and a sealing ring 22 is provided below the cover plate, which can improve the sealing effect.

[0044] The power supply for heating element 3 is AC power, with a supply voltage of 100V-120V or 220V-240V. The power supply for heating element 5 is a battery, with a supply voltage of less than 78V.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
