DETAILED DESCRIPTION OF THE EMBODIMENTS

(8) It is to be noted that the embodiments in the application and the characteristics in the embodiments may be combined under the condition of no conflicts. The disclosure is elaborated below with reference to the accompanying drawings and embodiments.

(9) Some embodiments of the present disclosure provide a steam generator, which includes: a boiler 10 having a combustion chamber 11. With reference to FIG. 1 and FIG. 2, the steam generator further includes: a windproof cover 20, at least a part of an ignition device of the steam generator being located in the windproof cover 20; an igniting cover 30, at least a part of the igniting cover 30 being located in the combustion chamber 11 and an outlet of the windproof cover 20 being located in the igniting cover 30; and an air inlet grating 40, the air inlet grating 40 being provided around the windproof cover 20 and connected with the windproof cover 20, and the air inlet grating 40 being located on an inner side of an air inlet of the igniting cover 30, to prevent airflow in the igniting cover 30 from flowing out from the inlet of the igniting cover 30.

(10) The steam generator in some embodiments of the disclosure includes the boiler 10, the windproof cover 20, the igniting cover 30 and the air inlet grating 40. Because at least a part of the ignition device of the steam generator is located in the windproof cover 20, and at least a part of the igniting cover 30 is located in the combustion chamber 11, the outlet of the windproof cover 20 is located in the igniting cover 30, the air inlet grating 40 is provided around the windproof cover 20 and is connected with the windproof cover 20, and the air inlet grating 40 is located at the inner side of the air inlet of the igniting cover 30. In this way, air in the igniting cover 30 is blocked by using the air inlet grating 40, so as to prevent the air in the igniting cover 30 from flowing out from the air inlet of the igniting cover 30, and then prevent the air from flowing back, thus the problem of airflow backflow which easily occurs in a car washer known to inventors is solved.

(11) To make it convenient for the air to flow in the igniting cover 30, as shown in FIG. 2, an airflow through hole 41 is provided on the air inlet grating 40, so that the airflow entering from an inlet of the windproof cover 20 flows towards a middle part of the igniting cover 30 after passing through the airflow through hole 41.

(12) In an exemplary embodiment, a spinning disk is provided at a bottom of the airflow through hole 41. By using the spinning disk, air flowing out from the airflow through hole 41 spirally enters the igniting cover 30 under an effect of the swirl vane.

(13) To facilitate the import of airflow, an extension direction of the airflow through hole 41 is inclined to an axial direction of the boiler 10.

(14) In an exemplary embodiment, as shown in FIG. 2, there are a plurality of airflow through holes 41, and the plurality of airflow through holes 41 are provided around the windproof cover 20. By arranging the plurality of airflow through holes 41, it is convenient for airflow to smoothly enter into the middle part of the igniting cover 30.

(15) In an exemplary embodiment, the airflow through hole 41 is spiral. A spiral angle of the airflow through hole 4 is less than 180 degrees. In this way, the airflow spirally enters into the middle part of the igniting cover 30.

(16) In some embodiments, the airflow through hole 41 is a quadrangular hole. At this point, a cross section, vertical to its extension direction, of the airflow through hole 41 is quadrangular.

(17) To facilitate mounting of the air inlet grating 40, as shown in FIG. 1 and FIG. 2, the air inlet grating 40 is an annular plate. The air inlet grating 40 is connected to the outlet end of the windproof cover 20 and is provided around the outlet of the windproof cover 20.

(18) In some embodiments, the steam generator includes an air inlet baffle 50 provided at the air inlet of the igniting cover 30. The air inlet baffle 50 is connected to a side wall of the igniting cover 30 and extends in a radial direction of the air inlet of the igniting cover 30. The air inlet grating 40 is located at a lower side of the air inlet baffle 50.

(19) It is apparent that an effect of preventing airflow from flowing back is further enhanced by using the air inlet baffle 50.

(20) In some embodiments, an annular gap is formed between an outside edge of the air inlet grating 40 and an inner wall of the igniting cover 30. In this way, airflow flows in the gap between the air inlet grating 40 and the inner wall of the igniting cover 30.

(21) In some embodiments, the steam generator further includes an air duct retainer ring 60. An air inlet end of the air duct retainer ring 60 is provided around an air outlet of the igniting cover 30 and is connected with the igniting cover 30. An air outlet end of the air duct retainer ring 60 is connected with an inner wall of the combustion chamber 11, so that the airflow in the igniting cover 30 enters the combustion chamber 11 after passing through the air duct retainer ring 60.

(22) To support the igniting cover 30, as shown in FIG. 2, the steam generator further includes: a mounting cover 70. The mounting cover 70 is located outside of the igniting cover 30 and the air duct retainer ring 60. A top of the mounting cover 70 is connected with the igniting cover 30, and a bottom of the mounting cover 70 is connected with the air duct retainer ring 60, so as to support the igniting cover 30 in the combustion chamber 11.

(23) In an exemplary embodiment, the igniting cover 30 includes a first conical barrel and a second conical barrel. A large end of the first conical barrel is in abutting joint with a large end of the second conical barrel. A small end of the first conical barrel is the inlet of the igniting cover 30, and a small end of the second conical barrel is the outlet of the igniting cover 30.

(24) Some embodiments of the disclosure also provide a car washer, which includes the abovementioned steam generator.

(25) It can be seen from above description that the above embodiments of the disclosure achieve the following technical effects.

(26) The steam generator in the disclosure includes the boiler 10, the windproof cover 20, the igniting cover 30 and the air inlet grating 40. Because at least a part of the ignition device of the steam generator is located in the windproof cover 20, and at least a part of the igniting cover 30 is located in the combustion chamber 11, the outlet of the windproof cover 20 is located in the igniting cover 30, the air inlet grating 40 is provided around the windproof cover 20 and is connected with the windproof cover 20, and the air inlet grating 40 is located at the inner side of the air inlet of the igniting cover 30. In this way, the air in the igniting cover 30 is blocked by using the air inlet grating 40, so as to prevent the air in the igniting cover 30 from flowing out from the air inlet of the igniting cover 30, and then prevent the air from flowing back, thus the problem of airflow backflow which easily occurs in a car washer known to inventors is solved.

(27) The above are only some embodiments of the disclosure and not intended to limit the disclosure; for those skilled in the art, the disclosure has various modifications and changes. Any modifications, equivalent replacements, improvements and the like within the spirit and principle of the disclosure should fall within the protection scope of the claims of the disclosure.
