Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a car wash machine that is formed into a portal shape and has a rotary brush, etc. inside a main body that moves back and forth across a car body, and relates to a car wash method using this type of car wash machine.

Conventionally, this type of car wash machine has, for example, a pre-washing process in which water or detergent water is sprayed during the first return trip, a washing process using foamed detergent during the first return trip, and a wax liquid used during the second return trip. There are some that wash and polish the car body by performing a waxing process and a drying process by blowing air during the second go-around. However, with this method, the wax liquid is sprayed immediately after using the foamed detergent that is highly adhesive to the car body during the first go-around, and the detergent and wax may mix and coagulate (C), or the wax may become coagulated. There is an inconvenience in that a large amount of water is sprinkled so that the liquid does not mix with the detergent, and the wax liquid is washed away without adhering to the car body sufficiently, making it impossible to obtain a sufficient polishing effect with the wax. In addition, as shown in Japanese Patent Publication No. 58-47380,
A two-way flushing method is known that includes a washing process, a rinsing process, a waxing process, and a drying process. However, in general, if you do not wash the sand, mud, etc. from the car body with a certain amount of water before washing, there is a risk that this sand, mud, etc. will be rubbed against the car body with a brush and scratch the painted surface. When water is used, most of the detergent is washed away before it acts on the car body, and there is a problem that stubborn dirt such as oil stains and water scale cannot be removed. The drawback is that cleaning only once at a time may not be enough to remove dirt, and there is a risk of damaging the painted surface of the car body if you try to remove it.

The present invention has been made to address the above-mentioned problems and provides a car washing method that provides sufficient cleaning and polishing effects.

The present embodiment has the above-mentioned configuration, and the operation when washing the automobile 50 will be explained below based on FIG. 4. Incidentally, the top brush 4 shown in the figure indicates that the process involves brushing work, and in this case, brushing is not limited to the top brush 4, but also the side brushes 3, 3' and rocker brushes 6, 6'' are performed at the same time.

During the first outgoing movement 1a of the main body 1, the watering nozzles 9 and 1 are first
At the same time as spraying water with 0, detergent water is sprayed from the detergent nozzle 11, and dirt such as mud and dust adhering to the car body is washed off while brushing.After this, detergent and dirt remaining on the car body are washed away by water sprinkling from the water spray nozzle 14. Drop it.

During the first return trip 1b, foamed detergent is sprayed from the detergent nozzle 13 and adhered to the vehicle body, and the dirt that was not removed during the return trip is thoroughly removed by brushing.

During the second outbound trip Ha, the car body is sprayed with water from the water nozzles 9 and 10 and then brushed to wash off the foaming detergent adhering to the car body, and the car body is further rinsed with water sprayed from the nozzle 14.

During the second go-around nb, air is blown onto the car body from the blower nozzle 7 to scatter and remove some water attached to the car body 50.

During the third outbound trip 1 [1a, the wax is rubbed thoroughly into the vehicle body by brushing while spraying wax solution from the wax nozzle 12, and then water is sprayed from the water nozzle 14 to wash away any excess wax.

During the third go-around mb, air is again blown onto the car body from the blower nozzle 7, and the water droplets that have been turned into water droplets by the wax treatment and remain on the car body are scattered and dried.

In this example, the car wash operation consists of three round trips as described above, and during the first round trip, a certain amount of water is used to wash away mud and dirt from the car body, and subsequent polishing with a brush removes scratches caused by mud, sand, etc. After setting it to a state where it does not give etc.,
During the return trip, foamed detergent is applied to the vehicle body and polishing is performed using a brush.The detergent and brushing are used to thoroughly remove individual dirt, and the detergent remaining on the vehicle body is washed away during the second outbound trip. Next, during the second go-around, the blower nozzle 7 was activated to remove a certain amount of water from the car body, making it in a sticky state, and then a waxing process was performed, and finally the blower nozzle 7 was activated again to dry the car body. Is going. Of the two drying processes using the blower nozzle 7, in the first process, the car body has almost no water repellency due to wax etc. immediately after washing with detergent, so even if air is blown, the water does not drain easily and the car body remains dry. A suitable film of water will remain on the surface of the vehicle, and during the next waxing process, this water film will effectively disperse the wax evenly over the surface of the car body.

This invention consists of the above-mentioned configuration and operation, and includes a pre-washing step in which the main body is brushed with only water or water sprayed with detergent during the first return trip, and a brushing step using at least foamed detergent during the first return trip. A cleaning process in which water is sprayed only or brushing with water is performed during the second return trip, a first drying process in which air is blown onto the unit during the second return trip to scatter adhering water droplets, and a third drying process is performed during the third return trip. Waxing process of brushing with wax liquid, 3rd
During the go-around, a second drying process is performed in which air is blown onto the car body to scatter water droplets, so sand and mud stains are washed away in the pre-washing process, oil stains and other dirt stuck to the car body are removed in the washing process, and dirt stuck to the car body, such as oil stains, is removed in the rinsing process. Rinse off any detergent left on the car body, and
In the drying process, part of the water adhering to the car body can be removed, waxing can be performed in the waxing process, and the car body can be dried in the second drying process, which cannot be achieved with the conventional two-way washing machine described above. High cleaning and wax polishing effects can be obtained at the same time. In particular, since waxing is applied after a certain amount of water on the car body is removed in the first drying process, there is no problem such as the wax liquid flowing down with the water on the car body before it acts on the painted surface, and a relatively small amount of water is removed. A sufficient wax finishing effect can be obtained with wax liquid.
