<p>Disclosed is a boiler for a steam cleaner, which includes a heat exchanger (1) and a heating component set on the heat exchanger (1). One of the surfaces of the heat exchanger (1) is a plane surface, on which a groove (12) is provided, and the groove (12) is communicated with a water inlet joint (18) and a steam nozzle (19) of the boiler. The upper part of the groove (12) is fixedly connected with a cover board (2) in a sealed way, and the internal wall of the cover board (2) seals up the groove (12) to form a steam generation chamber. The steam generation chamber contacts with the heat exchanger (1) sufficiently, which improves the heat exchanging efficiency of the boiler. The boiler is also provided with a second steam generation chamber (14) for using the residual heat of the heat exchanger (1). After passing through the second steam generation chamber (14), the steam is gasified completely, which ensures that the steam cleaner will not leak water any more.</p> |
