Description

  The present invention relates to a car wash machine that is installed, for example, in a gas station and used for car washing.

  Conventionally, cleaning by brushing in a car wash machine is performed by pressing a plurality of rotating brushes against the vehicle and removing the paint surface. However, equipment parts such as fender mirrors and rear mirrors may lead to equipment damage when the rotating brush hits the equipment even at low speeds. For this, brushing is performed avoiding the equipment, but in this case, the equipment and surroundings are not sufficiently cleaned. There is also a system that removes dirt with high-pressure water or ultrasonic water, but with the power of water alone, dirt on the painted surface can hardly be removed even if dust is removed.

In order to deal with such a problem, the following configuration is conventionally provided. That is, a cylindrical body to which high-speed air is supplied from a blower via a flexible supply pipe is provided, and an air ejection slit is provided at the lower part of the cylindrical body. A shaft body is provided in the longitudinal direction at the front and rear intermediate positions in the slit, and the base end of the soft sheet piece is attached to the shaft body. And it is comprised so that a soft sheet piece may be vibrated and car-washed, mixing water and detergent water with high-speed air in a cylinder, and ejecting a gas-liquid mixture from a slit (for example, refer patent document 1). .
