The existing disinfection cabinet is not provided with an exhaust fan or is provided with an internal circulation exhaust fan, moisture on tableware is heated into water vapor and then cannot be discharged out of the cabinet, and the water vapor is condensed in the cabinet after the temperature is reduced after the heating is finished, so that bacteria are easily grown in the cabinet. Some exhaust fans are arranged to exhaust water vapor, so that the cabinet is damp and moldy after a long time.

The existing front exhaust disinfection cabinet is generally provided with an exhaust port at the front part, the exhaust stage is generally gas with higher humidity and certain heat, and exhausted water vapor directly blows a human body to cause overhigh exhaust temperature to be scalded or clothes to be wet.

The air quality in the kitchen is generally poor, and the kitchen often has oil smoke smell or peculiar smell. The disinfection cabinet is generally installed below a kitchen range, and oil stains are scattered to the ground in front of the disinfection cabinet in the cooking process, so that the disinfection cabinet is greasy, wet and slippery, and peculiar smell can be generated. The negative ions can purify air and remove peculiar smell, but the diffusion range of the negative ions is limited, and the negative ions can be diffused rapidly in a large range under the action of wind force.
