Description

The present invention relates to a washing machine for washing an automobile by injecting washing water from a nozzle while rotating rotors of a plurality of nozzle devices mounted on a portal frame.

Generally, a washing machine used for washing an automobile removes dirt by a high-pressure jet jet ejected from a nozzle, and a rotating nozzle that injects washing water into the washing machine while rotating a rotor to which the nozzle is attached. An apparatus may be used (for example, Patent Document 1). In such a rotary nozzle device, since the spraying destination of the washing water changes with the rotation of the rotor, it is possible to wash a wide range of parts of the automobile by each device.

By the way, by equipping a gate-shaped frame with a plurality of nozzle devices to form a washing machine and injecting washing water from a plurality of nozzle devices into a car passing through the inside thereof, the whole car can be washed easily in a short time. can do.

In such a washing machine, the configuration can be simplified by supplying washing water from a common water supply channel to a plurality of nozzle devices, but by sharing the water supply channel, a certain nozzle device injects water. Since changes in the amount and pressure of the washing water affect other nozzle devices, it tends to be difficult to appropriately adjust the amount and pressure of the washing water ejected by each nozzle device.

On the other hand, by setting the amount and pressure of the washing water sprayed by all the nozzle devices to be the same, it is possible to easily adjust the amount and pressure of the washing water sprayed by each nozzle device.

However, automobiles have a mixture of relatively sturdy but heavily soiled parts such as tire wheels and relatively hard and easily damaged parts such as the upper surface of the car body, which are suitable for cleaning each part. It is required to inject cleaning water with a large amount of water and water pressure. In such automobile cleaning, if the amount and pressure of the cleaning water sprayed by all the nozzle devices are the same, if the amount and pressure of the cleaning water is increased so that it is suitable for cleaning severely soiled tire wheels, etc. Washing water with the same amount of water and water pressure may cause deformation of the vehicle body and peeling of paint.

An object of the present invention is to provide a washing machine capable of sufficiently cleaning a heavily soiled portion and preventing damage to a vehicle body while facilitating adjustment of the amount and water pressure of the washing water to be sprayed.

In order to achieve the above object, the washing machine according to the present invention supplies washing water to a gate-shaped frame through which an automobile passes, a plurality of nozzle devices mounted on the gate-shaped frame, and a plurality of nozzle devices. It is equipped with a common water supply channel, and its nozzle device is configured by providing a nozzle on a rotor that can rotate around the rotor shaft, and while rotating the rotor, it injects cleaning water from the nozzle to wash the automobile. As a rotary nozzle device, the injection direction of the nozzle is set to be inclined with respect to the central axis of the rotor shaft and spread in the radial direction, and the inclination angle of the injection direction of the nozzle for cleaning easily soiled parts is reduced. The injection directions of the nozzles of the plurality of nozzle devices are set to a plurality of inclination angles so as to increase the inclination angle of the nozzle for cleaning the portion that is hard to be soiled .

According to the above configuration, since the injection directions of the plurality of nozzle devices mounted on the portal frame are set to a plurality of tilt angles, that is, different tilt angles, the tilt angles are reduced for each nozzle device to reduce the cleaning power. It can be increased or the tilt angle can be increased to reduce the load on the cleaning site. Here, in the rotary nozzle device in which the injection direction is set to expand in the radial direction, the larger the inclination angle, the wider the cleaning range and the longer the distance to the cleaning portion, and moreover, the cleaning portion Since the injection is performed diagonally, the detergency and load per unit area are weakened.

As a result, the cleaning water having the same amount of water and water pressure is supplied to the plurality of nozzle devices from a common water supply channel, so that the amount of washing water and the water pressure can be easily adjusted, and the degree of dirt on the part to be cleaned The desired detergency and load can be set by setting the inclination angle of the nozzle according to the strength of the portion.

Specifically, for nozzle devices that clean relatively sturdy but heavily soiled parts such as tire wheels where mud tends to adhere and the front and rear parts of the vehicle body where insects tend to adhere, the nozzle injection direction. For the nozzle device that cleans the parts that are relatively hard to get dirty but are easily damaged, such as the upper surface of the car body and the side surface of the car body, by reducing the tilt angle of the nozzle, increase the tilt angle of the nozzle in the injection direction. The load on the part to be cleaned can be suppressed.

Further, the injection direction of the nozzle may be set to a direction in which the nozzle is inclined in the circumferential direction while expanding in the radial direction of the rotor shaft, and the washing water may be injected while rotating the rotor in reaction to the injection.

According to this configuration, since the rotor is rotated by the reaction of the injection, it is possible to eliminate the need for a dedicated configuration for rotating the rotor. In this case, the rotation speed of the rotor is affected by the amount and pressure of the washing water, and if the rotation speed is excessively increased, the washing water spreads due to centrifugal force and the washing range spreads, but the above-mentioned configuration is adopted. Then, by appropriately adjusting the amount and pressure of the washing water, the rotation speed of the rotor can be set to a predetermined speed, and a desired range can be washed.

As described above, according to the present invention, with respect to the injection directions of the plurality of nozzle devices mounted on the portal frame, the inclination angle of each nozzle device is reduced to increase the cleaning force, or the inclination angle is increased to increase the cleaning portion. It is possible to suppress the load of. As a result, for example, cleaning water having the same amount of water and water pressure is supplied to a plurality of nozzle devices from a common water supply channel, so that the amount and pressure of the cleaning water to be jetted can be easily adjusted, and a severely soiled part can be sufficiently removed. It can be cleaned and the car body can be prevented from being damaged.
