An embodiment of a second aspect of the present invention proposes a laundry treating apparatus including a cabinet and a steam generator 100, the steam generator 100 being the steam generator 100 proposed according to any of the above embodiments, the steam generator 100 being mounted in the cabinet. For example, the laundry treating apparatus in the present embodiment may be a drum type washing machine or a laundry dryer.

In the present embodiment, the steam generator 100 is installed in a clothes treating apparatus, and particularly, may be installed in the clothes treating apparatus in the form of a steam generator assembly 1000, the steam generator assembly 1000 includes the steam generator 100, a protective shell 200, a heat shield 300 and a fixing bracket 400, as shown in fig. 2, the heat shield 300 and the protective shell 200 are wrapped outside the shell 110 of the steam generator 100, and the protective shell 200 and the heat shield 300 are used for isolating the steam generator 100 from other components in the clothes treating apparatus, it can be understood that, since the heating device 120 in the steam generator 100 heats the shell 110 of the steam generator 100 during operation, the shell 110 of the steam generator 100 has a high temperature, and in order to avoid the high temperature from affecting other components in the clothes treating apparatus, the protective shell 200 and the heat shield 300 are covered outside the steam generator 100 in the present embodiment, and in addition, the protective shell 200 and the heat shield 300 are provided in the present embodiment, so as to prevent the heat generated by the steam generator 100 from being dissipated Accordingly, the efficiency of heating the water in the housing 110 is further improved, thereby improving the efficiency of generating steam.

Specifically, the heat shield 300 may be provided as a fiber heat shield 300, the heat shield 300 is wrapped outside the shell 110 of the steam generator 100, the protective shell 200 is covered outside the heat shield 300, and the heat shield 300 in this embodiment includes two portions: the steam generator comprises a first cover shell 310 and a second cover shell 320, wherein the first cover shell 310 and the second cover shell 320 can be connected through bolts or screws, the first cover shell 310 and the second cover shell 320 are buckled to form a containing cavity, and the steam generator 100 is contained in the containing cavity; the protective shell 200 is covered outside the heat shield 300 from the top of the heat shield 300, and the heat shield 300 and the protective shell 200 are respectively provided with windows for the steam outlet 101, the water inlet 102 and the like of the steam generator 100 to extend out. The present embodiment reduces the dissipation of heat of the steam generator 100 by providing the heat shield 300 and the shield case 200, using the heat shield 300 and the shield case 200, while preventing high temperature from affecting other components in the laundry treating apparatus.
