In this cleaning machine, a nozzle pipe for jetting a cleaning liquid is attached to a movable body that reciprocates along an upper edge of a long side wall of a cleaning tank formed in a rectangular parallelepiped shape, and the nozzle pipe is vertically opposed to each other. A pump is connected to the lower side in a suspended manner, and the movable body is configured to move the pump together with the nozzle pipe in the cleaning liquid.

In the cleaning of the object to be cleaned by the cleaning machine, a cleaning liquid is injected into a cleaning tank, and the pump is immersed in the cleaning liquid. Then, the object to be cleaned is placed on the support member arranged between the upper and lower nozzle pipes, and while the nozzle pipe and the pump are reciprocated in the cleaning tank by the movable body, the cleaning liquid is pumped to the nozzle pipe by the pump. Then, the object to be cleaned is washed from above and below. The object to be cleaned, which has been cleaned as described above, is taken out of the cleaning tank and set in a dryer to dry.

[0004]

[Problems to be solved by the present invention]
There is no particular hindrance to cleaning the object to be cleaned. However, the object to be cleaned after the cleaning is taken out of the cleaning machine, set in a dryer and dried. Therefore, it is necessary to move the object to be cleaned from the washer to the dryer, and the cleaning efficiency is reduced. In addition, when the object to be cleaned is moved to the dryer, the cleaning liquid adhered to the object to be cleaned is floor-mounted. There are problems such as dripping on the surface and wetting the clothes of workers. Further, since it is necessary to separately prepare a dryer, there is a problem that the cost is increased.

[0005] An air nozzle is attached to the movable body vertically in parallel with each of the nozzle pipes. When the cleaning of the cleaning object is completed, the jetting of the cleaning liquid is stopped, and the air is jetted from the air nozzle. It is conceivable to dry the object to be cleaned. However, since the cleaning liquid for cleaning the object to be cleaned enters the lower air nozzle, it is difficult to blow out the air from the air nozzle, or the cleaning liquid is spouted together with the air to dry the object to be cleaned. The problem that becomes difficult occurs.

SUMMARY OF THE INVENTION The present invention solves the above-described problems, and provides a washing machine that can dry a washed object without any trouble with air jetted from an air nozzle at that position. The purpose is to:

[0007]

According to the washing machine of the present invention, a movable body which reciprocates along a pair of rails provided on the upper portions of the opposed side walls of the washing tank is provided in a bridging manner between the pair of rails. The upper nozzle pipe of a pair of nozzle pipes which are provided in the vertical direction and eject the cleaning liquid in the opposite direction is attached to the movable body, and a pump is provided below the nozzle pipe with a connection pipe having high rigidity. It is connected in a suspended manner, and the pump moves together with the movable body in the cleaning tank, and the cleaning liquid in the cleaning tank is supplied to each nozzle pipe, and the pump is positioned between the nozzle pipes opposed vertically. In a washing machine in which a support member for an object to be cleaned is disposed in a horizontal direction, an upper air nozzle of a pair of air nozzles positioned above and below the support member and ejecting air in opposite directions is preferably the movable body. The end of the cover plate which is attached and overlaps the upper side of the air nozzle of the air nozzle which jets air upward at the bottom side in the cleaning tank, and covers the entirety of the air nozzle, is attached to the mounting portion provided on the air nozzle. A biasing means is attached to the covering plate so as to be swingable in a vertical direction, and biases the covering plate in a downward direction to overlap the covering plate on the spout. Contrary to this, it is characterized in that the cover plate can be swung upward by the pressure of the air jetted from the jet port.

A weight or a spring is used as the urging means for the cover plate. If a weight is used, it is attached to the covering plate.If a spring is used, a kick spring is attached to a shaft attachment portion of the covering plate, or a tension spring is provided between the covering plate and a fixing member such as an air nozzle. Stretch.

[0009]

In the washing machine of the present invention, the object to be washed is placed on the support member, and the movable body is reciprocated along the rail, and the washing liquid is ejected up and down by a pair of nozzle pipes.
The object to be cleaned is cleaned from both upper and lower directions. At the time of this cleaning, the coating plate overlying the air nozzle of the air nozzle located at the lower part of the cleaning tank is closed to prevent the cleaning liquid from entering the air nozzle from the air nozzle. When the cleaning of the object to be cleaned is completed, the jetting of the cleaning liquid is stopped, and air is jetted from a pair of upper and lower air nozzles by a blower. Then, although the ejection port of the lower air nozzle is covered with the covering plate as described above, the ejected air collides with the covering plate, and the pressure exerts on the covering plate against the force of the urging means. Then, the object to be washed is dried while maintaining the state of being swung upward and spouting upward to dry the object to be washed after the washing. When the drying of the object to be cleaned is completed and the air ejected from each air nozzle is stopped, the urging means swings the covering plate downward to overlap the ejection port of the lower air nozzle, and from the ejection port. It is repeated to prevent the washing liquid from entering. This washing machine continuously performs washing and drying of a washing object as described above.
