During the cleaning process of the flue 10, grease and sewage in the flue 10 are discharged into the oil storage tank 15 to be stored, after the flue 10 is cleaned, the second automatic valve is opened, water in the ultrasonic cleaning tank is discharged into the oil storage tank 15 to be stored, the grease and the sewage in the oil storage tank 15 are mixed with hot water discharged from the ultrasonic tank 20, the third automatic valve 16 is closed, the ultrasonic generator 24 vibrates to drive the oil storage tank 15 to vibrate, so that the grease is dissolved, emulsified and suspended in water in a dispersing manner, the drain valve 17 is opened, the decomposed grease is discharged from the drain valve 17 along with the sewage, clean water is injected into the ultrasonic tank 20 through the water pump and the water inlet 21 to cool the ultrasonic tank 20, meanwhile, cold water enters the oil storage tank 15 through the ultrasonic tank 20 to rinse the oil storage tank 15, and the rinsed sewage is discharged from the drain valve 17. After completion, the ultrasonic generator 24, the second automatic valve and the blow-off valve 17 are closed.
Because after culinary art at every turn is finished, the inside water of ultrasonic case 20 is heated to certain temperature with the inside flue gas heat transfer of flue 10 after, and the inside water yield of ultrasonic case 20 is limited in addition, therefore this range hood fire protection system is applicable to family expenses, and the length of time of cooking is limited and have certain time interval between the three meals a day when family cooks, and between adjacent twice culinary art, the inside water of ultrasonic case 20 can cool off naturally to convenient use when cooking next time.
The specific implementation process is as follows:
before the first cooking, the first automatic valve is opened, and the first automatic valve is closed after the water pump is used for filling water into the ultrasonic box 20; in the cooking process, the third automatic valve 16 is opened, the exhaust fan exhausts air, the oil smoke enters the flue 10, when the smoke meets the guide plate 18, the guide plate 18 enables the smoke to move towards the inner side wall of the flue 10, the water inside the ultrasonic box 20 cools the flue 10 and the smoke in the flue 10, and substances such as grease, water vapor and the like in the oil smoke are condensed on the inner side wall of the lower portion of the flue 10 when meeting cold and then flow into the oil storage box 15 to be stored.
When the grease inside the oil reservoir 15 reaches a certain amount, the flue 10 needs to be cleaned. The electric heating plate 23 is turned on to heat water in the ultrasonic box 20, the ultrasonic generator 24 is turned on to perform ultrasonic vibration on the water in the ultrasonic box 20, the mixture of the grease and the water on the inner side wall of the flue 10 is subjected to the ultrasonic vibration to generate emulsification, meanwhile, the water-oil mixture is heated and melted to flow to the bottom of the flue 10 along the flue 10 and then flow into the oil storage tank 15, and the ultrasonic waves can also clean water scales on the outer wall of the flue 10.
After the flue 10 is cleaned, the cleaning agent pump 31 is closed, the second automatic valve is opened, grease and sewage in the flue 10 and hot water in the ultrasonic cleaning tank are discharged into the oil storage tank 15 to be mixed, the third automatic valve 16 is closed, the ultrasonic generator 24 vibrates to drive the oil storage tank 15 to vibrate, so that the grease is dissolved, emulsified and suspended in water in a dispersing way, the blow-down valve 17 is opened, the decomposed grease is discharged from the blow-down valve 17 along with the sewage, then clear water is injected into the ultrasonic tank 20 through the water pump and the water inlet 21 to cool the ultrasonic tank 20, meanwhile, cold water enters the oil storage tank 15 through the ultrasonic tank 20 to rinse the oil storage tank 15, and the rinsed sewage is discharged from the blow-down valve 17. After completion, the ultrasonic generator 24, the second automatic valve and the blow-off valve 17 are closed.
In the embodiment, the smoke is cooled firstly, the grease is condensed at the lower part of the flue 10, then the grease is heated and sprayed with the cleaning agent, and meanwhile, the grease in the flue 10 is thoroughly cleaned by ultrasonic vibration, so that the fire in the flue 10 is avoided, and the smoke exhaust ventilator is suitable for fire prevention of a household smoke exhaust ventilator. The problem of the inside grease clearance of flue 10 inconvenient is solved.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail.
