Disinfection device and dish washing machine

The invention discloses a disinfection device and a dish washing machine, and relates to the technical field of disinfection equipment. The device comprises a water tank, a dielectric barrier discharge assembly, an air pump, a condensation pipe and a flow guide pipe, and the dielectric barrier discharge assembly is arranged in the water tank and extends out of the water tank. The dielectric barrier discharge assembly is communicated with a water tank gas circuit. The air pump is communicated with the dielectric barrier discharge assembly through an air path. The condensation pipe is in air channel communication with the water tank and the air pump and conducts condensation and dehumidification on air flowing out of the water tank. The flow guide pipe located below the condensation pipe is communicated with the condensation pipe water way and the water tank water way so that condensate water in the condensation pipe can be guided into the water tank. Therefore, air flowing out of the water tank is dehumidified
