The invention discloses a haze-proof traffic lamp, belonging to the field of traffic lamps, and particularly relating to a haze-proof traffic lamp. The haze-proof traffic lamp comprises a lamp frame and a signal control box, wherein the lamp frame comprises a transverse frame and an upright post; the transverse frame is provided with a traffic lamp; the traffic lamp is connected with the signal control box through an electric wire. The haze-proof traffic lamp is characterized in that a mist-absorbing pipe is arranged at the bottom of the upright post, and is connected with a mist-absorbing pump; the mist-absorbing pump is connected with a mist filter. The haze-proof traffic lamp further comprises an electronic projector which is arranged on the transverse frame and connected with the signal control box, and can be used for displaying real-time traffic signals synchronously to the traffic lamp and projecting the traffic signals onto the ground or opposite vehicles in real time. By adopting a haze clearing device, haze around the traffic lamp can be cleared in time to keep traffic signals clear. Even on a hazy weather, pedestrians and vehicle drivers can distinguish current real-time traffic signal display clearly and pass through road junctions safely according to signal instructions, thereby avoiding traffic accidents.

The invention provides a washing machine and a control method therefor. The washing machine comprises an inner barrel and an outer barrel. The inner barrel is only provided with water discharge holes in the upper portion of the barrel body and the other parts are sealed; the inner barrel is a water holding barrel; the outer barrel is inside provided with a heating device; a chamber between the inner barrel and the outer barrel forms a water heating space; the water heating space communicates with the inner barrel via a circulating water system; heated water is guided into the inner barrel or water in the inner barrel is heated through heat transfer of the inner barrel. The washing machine is provided with a first water quantity detection unit used for detecting the water inflow quantity of the inner barrel and a second water quantity detection unit used for detecting the water inflow quantity of the chamber between the inner barrel and the outer barrel. Water is first delivered to the chamber between the inner barrel and the outer barrel to be heated and is then guided into the inner barrel via the circulating water system, or water in the inner barrel is heated via heat transfer of the inner barrel, so that high temperature heated washing is realized, the washing efficiency and the cleaning ratio are increased and the objective of disinfection and sterilization is achieved. The structure is simple and the heating efficiency is high.
