detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

As shown in Figures 1 to 3, the integrated heating and steam generator is characterized in that it includes a working cavity 1 with a water inlet 11, a heating tube 2 is arranged on the inner wall of the working cavity 1, and the working cavity Fins 3 are provided on the outer wall of the body 1, and a steam port 12 communicating with the interior of the working chamber 1 is provided; when there is no water in the working chamber 1, the air outside the working chamber 1 is heated by the heating tube 2 ; When there is water in the working cavity 1, the heating tube 2 heats the water in the working cavity 1 to generate steam and discharge it through the steam port 12.

The steam port 12 is connected with a steam spray head through a pipeline, and the steam spray head is equipped with a mechanical pressure switch. When there is water in the working chamber 1, if the pressure inside the working chamber reaches the eruption pressure of the steam nozzle, the mechanical pressure switch attached to the steam nozzle is turned on, and the steam generated inside the working chamber will be sprayed out through the steam nozzle.

The working cavity 1 is provided with an explosion-proof port 13 communicating with its interior, and the explosion-proof port 13 is provided with a rubber seal. When the pressure inside the working cavity is greater than or equal to the destruction pressure of the explosion-proof port, the rubber seal is destroyed to release The pressure inside the working cavity prevents the internal pressure of the working cavity from being too large, which will cause the working cavity to explode, and the destruction pressure of the explosion-proof port is 1.5-2.5 times of the eruption pressure of the steam nozzle.

In order to realize the automatic control of the integrated heating and steam generator, a control unit is also provided, the heating tube 2 is an electric heating tube, and the heating tube is electrically connected to the control unit.

The distribution patterns of the fins 3 are various; The fins are distributed along the circumferential direction of the outer wall of the working cavity.

The distribution patterns of the heating tubes 2 are various, as shown in Figure 3, Figure 6 and Figure 7, the heating tubes can be bent and arranged on the inner wall of the working cavity, and the two ends of the heating tubes are separated from the same side wall of the working cavity. The two ends of the heating tube can also protrude from the two side walls of the working cavity; there are many ways to bend the heating tube on the inner wall of the working cavity.
