<p>Disclosed is a boiler for a steam cleaner, which includes a casing (2) and a heat exchanger (1) jacketed by the casing (2). The casing (2) is provided with a water inlet joint (21) and a steam nozzle (22). A heating component is set on the heat exchanger (1), and the external surface of the heat exchanger (1) is provided with a groove (12), which is communicated with the water inlet joint (21) and the steam nozzle (22) on the casing (2), and is sealed up by the internal wall of the casing (2) to form a steam generation chamber. The steam generation chamber contacts with the heat exchanger (1) sufficiently, thereby improving the heat exchanging efficiency of the boiler.</p> |
