Description

A VEHICLE (AUTOMOBILE) DRYING AND DISINFECTING MACHINE
Field of the Invention
The present invention relates to a drying system which is used in drying process of vehicles and is also capable of disinfecting at the same time.
Background of the Invention
In the current technique, the process of washing vehicles is carried out in the form of car washing machines (car wash machines) or washing with pressurized water after applying a detergent. Car wash companies prefer not to use pure (deionized) water when washing vehicles due to its high cost. The tap or well water which is preferred to be used creates an appearance on the vehicle similar to a lime stain when it dries on the vehicle. To prevent this stain, a process of drying with a cloth or a rinse aid is applied and then air-drying is carried out.
Since 100% cleaning cannot be achieved with pressurized water, especially in the winter months, in the process of drying with a cloth, the dirt remaining on the surface of the vehicle acts as a scouring powder during the drying with the cloth and scratches the vehicle. In this application, most of the time, the actual cleaning is done while drying with a cloth. It is possible to easily see oval scratch marks when one looks at any vehicle from the right angle. If you look at 2-3 years old or older dark colored vehicles in a sunny weather, these marks can be seen much more easily.
The dryers used in the current technique are in the form of a structure with pole having an inverted U letter on a ground surface so that the vehicle can pass therethrough, and the drying process is carried out by means of the blowers present on this structure while the vehicle is passing through this structure. In another system, the structure with the inverted U letter moves linearly and the vehicle is passed under it. On the other hand, these systems cannot be used at places where the height of the ceiling is insufficient, they create a high level of noise, the vehicle needs to be moved back and forth, and if the heights of the vehicle and the device cannot be adjusted, drying cannot be carried out sufficiently. Therefore parts of the vehicle remain wet. When all technical problems are considered, there is a need for a dryer which is financially accessible to small and medium-sized washers that wash 10-30 vehicles a day, whose performance is efficient and which can operate without scratching the vehicles.
In the current technique, depending on the use of the vehicle, there can be virus/bacteria/germ etc. inside the vehicle. Therefore, if the consumer also demands disinfection of the vehicle as well as cleaning the vehicle, an additional spraying system is required.
Turkish Patent application no 2015/07786, an application known in the state of the art, relates to a car wash system comprising a framework surrounding the vehicle which is used for non-contact cleaning of the vehicle and at least two upper washing units on the framework which carry out the washing, rinsing and drying processes of the vehicle by spraying soap, water, air onto the vehicle.
Summary of the Invention
The objective of the present invention is to perform the drying process of vehicles in an easy and electricity-efficient way.
The objective of the present invention is to provide a drying and disinfecting system that can perform the drying and disinfection of vehicles. The objective of the present invention is to provide a drying system which can reach all parts of the vehicle and which can dry areas that even mobile dryers cannot completely dry.
