Description

Technical Field

[0001] This utility model belongs to the technical field of exhaust fan cabinets, specifically relating to an intelligent cleaning system for exhaust fan cabinets. Background Technology

[0002] In exhaust fan cabinets, a large amount of smoke generated during the exhaust process is absorbed into the fan, making cleaning and maintenance inconvenient. Over time, grease accumulates in the pipes and inside the fan, affecting exhaust efficiency. Furthermore, cleaning relies on manual operation, which is time-consuming and labor-intensive. Patent CN201110586Y discloses an automatic cleaning range hood. It uses a heating element to heat and melt grease and oil, which then automatically flows into the oil cup, thus cleaning the range hood. This eliminates the need for disassembly and reassembly, greatly simplifying cleaning. Since disassembly is unnecessary, it prevents air leakage, preventing grease from escaping and polluting the kitchen and other environments. However, its cleaning range is limited, and its intelligence level is not high. Utility Model Content

[0021] The intelligent cleaning system employs the principle of compressed air pulse jet dust removal, combined with chemical foaming softening and high-temperature steam dissolution, to achieve efficient removal of internal oil stains from the components to be cleaned. Chemical foaming increases the contact area with the oil stains, high-temperature steam enhances the dissolution efficiency, and compressed air pulses effectively remove deposits from the inner walls of the pipes, ensuring that the cutting force of the fan impeller is not affected and extending the equipment's service life.

[0023] A sludge collection port 37 is provided at the lower end of the component 24 to be cleaned. The sludge collection port 37 is connected to a sludge collection hose 38. The sludge collection hose 38 is connected to a drain pipe 38 and a compressed air pipe 40 via a T-connector. A compressed air vacuum conveyor 41 is provided at the T-connector. One end of the compressed air pipe 40 is connected to a chemical storage foaming tank 26 and a dry air compressor and air storage tank 28 via a T-connector. The other end is also connected to the compressed air vacuum conveyor 41 and a compressed air pulse valve 42 via a T-connector. A compressed air vacuum conveying solenoid valve 43 is provided on the pipe connected to the compressed air vacuum conveyor 41. A compressed air pulse jet descaling solenoid valve 25 is provided on the pipe connected to the compressed air pulse valve 42.

[0024] In the entire cleaning system, the opening and closing of the steam solenoid valve 33, the chemical solenoid valve 35, the compressed air vacuum delivery solenoid valve 43, and the compressed air pulse jet descaling solenoid valve 25 are controlled by the intelligent cleaning controller 44 via control lines. The intelligent cleaning controller 44 is equipped with a positive power supply 44-1, a negative power supply 44-2, a one-button start control line 44-3, a pause control line 44-4, and a reset control line 44-5 to realize various functions.

A chemical outlet valve 26-5 is provided inside the chemical foaming device 26-4.

[0026] Intelligent Cleaning System: Artemisia contains volatile oils (such as eucalyptus oil and camphor). During combustion, some of these oils are not completely decomposed, forming a viscous oil film that easily adheres to object surfaces. The tar produced by incomplete combustion (containing polycyclic aromatic hydrocarbons and phenolic compounds) hardens upon cooling and combines with dust to form a "composite dirt." Aldehydes (such as formaldehyde) and phenolic substances in the smoke oxidize in the air, forming cross-linked polymers, transforming the stain from "physical adhesion" to "chemical bonding." Some pyrolysis products (such as organic acids) react chemically with the material surface, transforming the stain from simple chemical residue to biological pollution. This "adhesion-penetration-oxidation" pollution chain requires the synergistic action of physical dissolution, chemical decomposition, and mechanical removal. Therefore, this invention achieves this through the following methods.

[0027] When the intelligent cleaning controller 44 receives the cleaning command, it automatically opens the chemical solenoid valve 35. The chemical solution is pre-added to the chemical storage foaming tank 26. The chemical solution is sprayed into the component 24 to be cleaned through the pipe 32, the chemical solenoid valve 35, the check valve 36, the tee 30, and the steam nozzle 29-1. The amount of chemical solution sprayed can be modified through the system settings. Under normal circumstances, it takes 3-5 seconds. After the chemical solution is sprayed, it is necessary to wait 10-15 minutes for the cleaning solution to react and decompose with the moxibustion oil stains. Then, the steam solenoid valve 33 is automatically opened. High-temperature steam is sprayed into the cleaning component 24 through the steam pipe 31, the steam solenoid valve 33, the steam check valve 34, the tee 30, the high-pressure hose 29, and the nozzle 29-1. The high-temperature steam from the steam generator 27 is used to fully dissolve the moxibustion oil stains again. The time is 5-10 minutes, which can be set by the system. After dissolution, the compressed air pulse jet descaling solenoid valve 25 automatically opens. High-pressure pulses of compressed air, via compressed air pipe 40, compressed air pulse jet descaling solenoid valve 25, and compressed air pulse valve 42, remove dirt from the inside of the component to be cleaned. Simultaneously, the compressed air vacuum conveying and draining solenoid valve 43 opens, and the removed dirt and wastewater are discharged into the drain pipe 39 via compressed air pipe 40, compressed air vacuum conveying and draining solenoid valve 43, compressed air vacuum conveyor 41, sludge collection port 37, and sludge collection hose 38, completing the cleaning process. Regular cleaning in this manner, approximately every 60 hours of use, is recommended. Experiments have shown that if cleaning is delayed beyond 60 hours, the cleaning difficulty increases significantly, ensuring the cleaning effect on the component remains unaffected and achieving good smoke extraction.

[0028] Example: The cleaning assembly includes a chemical storage foaming tank 26, a steam generator 27, a dry air compressor and air tank 28, and a solenoid valve assembly. A high-pressure hose 29 is connected to a steam pipe 31 and a chemical pipe 32 via a T-connector 30. A spray head 29-1 is provided at the connection point between the high-pressure hose 29 and the component to be cleaned 24. A sludge collection port 37 discharges sludge via a compressed air vacuum conveyor 41.

[0029] Working principle: After the intelligent cleaning switch is triggered, the intelligent cleaning controller 44 controls the operation of each component according to the preset sequence: the chemical solenoid valve 35 is automatically opened, the chemical solution is added in advance to the chemical solution storage foaming tank 26, and the chemical solution is sprayed onto the impeller of the blower 24 through the pipe 32, the chemical solenoid valve 35, the check valve 36, the tee 30, the chemical solution spray head and the steam nozzle 29-1 for 5 seconds. After the chemical solution is sprayed, wait for 10 minutes to allow the cleaning solution to react and decompose the moxibustion oil stains, and then automatically open the steam solenoid valve 33. High temperature steam is sprayed into the blower 24 and onto the impeller through the steam pipe 31, the steam solenoid valve 33, the steam check valve 34, the tee 30, the high pressure hose 29 and the nozzle 29-1. The high temperature steam is used to fully dissolve the moxibustion oil stains again for 5 minutes. After dissolution is complete, the compressed air pulse jet descaling solenoid valve 25 is automatically opened. The high-pressure pulse of compressed air is used to remove dirt from the impeller of the blower through the compressed air pipe 40, the compressed air pulse jet descaling solenoid valve 25, and the compressed air pulse valve 42. At the same time, the compressed air vacuum conveying and sewage discharge solenoid valve 43 is opened. The removed dirt and sewage are discharged into the sewage discharge pipe 39 through the compressed air pipe 40, the compressed air vacuum conveying and sewage discharge solenoid valve 43, the compressed air vacuum conveyor 41, the sewage collection port 37, and the sewage collection hose 38, and the cleaning is completed.

[0030] Results: Highly effective decontamination. The foaming technology of the cleaning solution increases the contact area between the solution and the grease, improving the softening effect. The high temperature of the steam further enhances its ability to dissolve stubborn stains. The combination of these two technologies achieves highly efficient removal of grease from the internal components being cleaned, ensuring the exhaust efficiency and lifespan of the blower. Anti-clogging design: The compressed air pulse jet principle effectively removes dirt adhering to the inner walls of pipes and the blower impeller, preventing pipe blockage and maintaining the normal operation of the system. Automated process: After one-button start, the system automatically completes the entire process of cleaning solution spraying, delayed softening, steam cleaning, and pulse discharge, requiring no manual intervention. This greatly reduces the labor intensity of equipment maintenance and improves cleaning efficiency and reliability.
