Description

Multi-pipeline instant steam generator and its application

Technical field

The invention belongs to the field of steam cleaning equipment, and particularly relates to an instant steam generator suitable for a steam type cleaner.

Background technique

Existing steam cleaner products mostly use instant steam generators and boiler steam generators. However, most of the hot steam generators on the market generally have short life, insufficient water vaporization, and excessive internal pressure of the steam generator. If the internal pressure of the steam generator is too high, the safety venting valve will be frequently opened, and there will still be a steaming process after the shutdown. There is a hidden danger that causes the user to be burned and other safety accidents. If the water vaporization is insufficient, the energy is not wasted. As well as the effect of steaming, the short life span directly leads to a short life of steam cleaning products using such steam generators. At present, European countries have introduced updated safety standards for these products, taking into account the safety of users - "Cl.22.106": modified for all steam cleaners (original standard only for pressure steam cleaners) Within three seconds after the switch is released, if the temperature of water vapor or water droplets exceeds 50 °C, the appliance should stop spraying/water; when it is in non-spraying state, all steam cleaners should be configured except for the instantaneous steam cleaner. One device makes its switch lockable; for a pressure steam cleaner, when the boiler pressure is greater than 35KPa, the water-filled lid should not be opened; to avoid damage caused by hot steam and hot water spray, for pressure steam The washing machine, the water-filled lid must be allowed to open until the pressure in the boiler drops to atmospheric pressure (hereinafter referred to as "3 second gas-stopping standard", see "Steam cleaner EN60335-2-54_A11 2012 standard update"). The rigor of this regulation will probably result in the existing instant steam generators will not meet the requirements.

In addition, the boiler-type steam generator is steam-stable, and it can meet the above-mentioned 3-second gas-stopping standard, but its steam waiting time is long, the internal pressure of the boiler-type steam generator is large, the helmet is improperly used or the debugging is poor. It will cause steam squirting accidents and burn people. The use of such boiler-type products also has great limitations (only standing upright and slightly lateral) and complicated processing, manufacturing and assembly processes, high defect rate and high cost.
