Meanwhile, the controller 5 can control the first switch valve 471 to be closed and the second switch valve 491 to be opened so as to enable the second pipeline 47 to be closed and the fifth pipeline 49 to be opened, and further clean water in the clean water box 48 can be pumped by the clean pump 44 under the control of the controller 5, and then is conveyed into the first steam generator 41 to be heated, sprayed into the inner cavity 10 through the first pipeline 46 and the nozzle 461, and the inner wall of the inner cavity 10 is flushed.

In some embodiments, the controller 5 is in signal connection with the circulation pump 42. Therefore, after the cleaning process and the rinsing process are finished, the controller 5 can control the circulation pump 42 to pump the liquid in the inner cavity 10, and pump the pumped liquid into the cleaning box 43 through the third pipeline 421 for collection, so as to realize the intelligent and efficient cleaning function and cleaning effect of the inner cavity 10.

In some embodiments, a turbidity sensor (not shown) is disposed in the sump 113 of the inner chamber 10, the turbidity sensor being configured to detect a turbidity value of the liquid in the sump 113 of the inner chamber 10, the turbidity sensor being in signal communication with the controller 5. The turbidity value of the liquid in the water collecting tank 113 of the inner cavity 10 is detected by the turbidity sensor, so that the dirt degree in the inner cavity 10 can be known, and the controller 5 can intelligently control the cleaning parameters such as the time of circulating cleaning, the time of flushing, the cleaning water temperature and the like.

Referring to fig. 2-13, in some embodiments, the first steam generator 41 is provided with two outlet ends. Meanwhile, two first pipelines 46 are provided, the two first pipelines 46 are connected with two outlet ends of the first steam generator 41 in a one-to-one correspondence, and at least two nozzles 461 are formed in the inner cavity 10. The two nozzles 461 are spaced apart and directed toward different areas of the internal chamber 10. Accordingly, the steam generated from the first steam generator 41 can be sprayed into different areas of the inner chamber 10 through the two nozzles 461, thereby improving the cleaning effect of the inner wall of the inner chamber 10.

In some embodiments, the first steam generator 41 is provided with a plurality of outlet ends. Meanwhile, the first pipelines 46 are provided with a plurality of first pipelines 46, the first pipelines 46 are connected with a plurality of outlet ends of the first steam generator 41 in a one-to-one correspondence manner, a plurality of nozzles 461 are formed in the inner cavity 10, and the nozzles 461 face different areas of the inner cavity 10.
