Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for cleaning upholstery covering surfaces such as chairs, sofas, car seats, ceilings, and walls and floors of houses.

(Prior art) Conventionally, methods for cleaning the upholstery as described above include soaking a cloth or the like in a cleaning solution and rubbing the surface of the upholstery with the cloth, or cleaning the surface of the upholstery in particularly heavily soiled areas. For stains, a cleaning solution was sprayed onto the covering material using a method such as spraying, and then this was wiped off with a cloth or the like. However, according to the conventional method, in order to remove stains from the surface material, the surface material is impregnated with a cleaning liquid or wiped. It takes a considerable amount of time to dry the cleaning liquid that has penetrated between the fibers that make up the surface. Furthermore, since the cloth used to wipe the covering material only rubbed the surface of the covering material, it was possible to remove stains from only the surface of the fibers of the covering material, but it was impossible to remove dirt from inside the fibers. Furthermore, with this wiping method, it is difficult to remove dirt from corners or recesses of walls and the like. Furthermore, if a large amount of cleaning solution is used to remove dirt from the surface material, if the surface material is made of cloth, the cleaning solution will penetrate inside the surface material and penetrate into the inside of the surface material. On the other hand, there was a problem in that the dirt on the surface of the covering material was raised on the surface of the covering material, and this dirt became noticeable after the cleaning solution had dried.

In other words, with conventional methods, it is not only difficult to clean vertical surfaces such as walls or uneven surfaces, but also it takes time to dry the surface material wet with the cleaning solution. It has the disadvantage that it cannot sufficiently remove dirt from the surface.

(Purpose) The first and second inventions described herein have been made in order to solve the above problems, and their purpose is to clean the surface of the covering material even if it is vertical or uneven. To propose a cleaning method that can efficiently perform cleaning, speed up the drying of a covering material after cleaning, shorten the cleaning time, and prevent excess cleaning solution from scattering around. Another object of the present invention is to propose a cleaning method that can increase the cleaning effect.

(Structure) First, the cleaning method according to the first invention sprays the cleaning liquid in the form of a mist at a spray pressure of about 2 atmospheres onto the surface of the surface material to be cleaned, and at the same time sucks the cleaning liquid. This is to clean the surface of the covering material to be cleaned. In other words, the dirt adhering to the surface material is instantly removed by washing it off in the flow of spraying and suction of the cleaning liquid.

To explain this with a schematic diagram, as shown in FIG. 1, first, if the covering material 3 is made of cloth,
The fibers 4 on the surface have various deposits 7 attached thereto, which are dirt. A cleaning solution is sprayed toward this from the X direction. The deposits 7 adhering to the fibers 4 of the covering material 3 are eluted from the fibers 4 by the sprayed cleaning liquid and incorporated into the cleaning liquid. At the same time, cleaning liquid is being sucked from the Y direction. Therefore, as shown by the arrow in FIG.
An air current flows from the direction to the Y direction, and the cleaning liquid that has dissolved the deposits 7 is carried along this flow, removing the deposits 7 that have become stains on the covering material 3.
It instantly removes the Then, by performing this process continuously and moving sequentially in the direction of arrow A, the facing material 3 that becomes the surface to be cleaned is
It cleanses the whole thing.

According to this method, compared to the conventional methods of applying a cleaning solution and wiping with a cloth, or wiping with a cloth impregnated with a cleaning solution, the cleaning surface of the facing material 3 is almost completely covered with the cleaning solution. It has the remarkable effect of not leaving the product in a wet state. Therefore, the cleaning solution dries quickly, and the drying time can be significantly shortened. Furthermore, it is possible to cleanly remove dirt inside the covering material 3 that cannot be removed by simply wiping with a cloth.

Next, the cleaning method according to the second invention will be explained. This cleaning method is a method in which, in addition to the cleaning method of the first invention, the cleaning effect on the surface to be cleaned is further increased. In other words, the feature is that a process of rubbing the surface to be cleaned is added between the process of spraying and suctioning the cleaning liquid onto the surface to be cleaned, and the surface of the covering material is cleaned while being rubbed while being cleaned at the same time. The purpose is to continuously remove the liquid instantaneously. Rubbing the surface to be cleaned includes, for example, rubbing the surface of the upholstery with a brush, rubbing the fibers of the upholstery against each other by vibration, and the like.

FIG. 2 is a schematic diagram showing the case where the rotating brush 5 rubs the surface to be cleaned. In the figure, the cleaning liquid is sprayed toward the facing material 3 from the X direction. The rotating brush 5 rotates in the direction of arrow B with the brush tip 6 in contact with the fibers 4 on the surface of the upholstery 3 to rub against the fibers 4 on the upholstery 3. and,
Suction is performed from the rear of the rotating brush 5 in the Y direction. Therefore, due to the friction with the rotating brush 5, the deposits 7 attached to the fibers 4 of the covering material 3 are separated, and further, the deposits 7 pushed backward by the rotation of the rotating brush 5 are moved in the Y direction. It's sucked towards you. As a result, the deposits 7 contaminating the covering material 3 are instantly removed from the covering material 3.

In this second method, the cleaning effect is further increased due to the synergistic effect of the action of dissolving the deposits 7 etc. by the cleaning liquid and the action of separating the deposits 7 etc. from the surface to be cleaned by friction. This can further improve cleaning efficiency.

In the above case, the cleaning liquid may be sprayed from between the brushes 6, so that the spraying of the cleaning liquid and the friction of the surface to be cleaned are performed at the same time.

In the first and second methods described above, the cleaning liquid is sprayed in the form of a mist. This is because the cleaning liquid adhering to the surface of the covering material is suctioned together with air to remove the cleaning liquid instantaneously, and this is to ensure efficient and reliable suction. Further, by forming the cleaning liquid into a mist, it is possible to easily create a flow of the cleaning liquid as shown by the arrows in FIGS. 1 and 2. Furthermore, by forming the cleaning liquid into a mist, it is possible to wash a covering material having a large number of raised fibers on its surface by spreading the cleaning liquid inside the spaces between the fibers.

However, the sprayed cleaning solution must not penetrate too far into the facing material. This is because it takes time to suction and dry the cleaning solution. Therefore, it is preferable to spray the cleaning liquid at a spraying pressure of about 2 atmospheres.

Incidentally, it is preferable to spray the cleaning liquid in a sequential manner within as narrow a range as possible.

(Example) An example of the cleaning method according to the present invention will be described below. FIG. 3 shows a state in which the seat portion of an automobile is being washed. Now, the worker is
A spray gun 1 for spraying a cleaning liquid and a suction duct 2 for suctioning air are held in hand, and these spray gun 1 and suction duct 2 are brought close to each other. Immediately after spraying the cleaning liquid onto the upholstery 3 of the seat with the spray gun 1, the operator uses the spray gun 1 and suction while causing the suction duct 2 to suck the cleaning liquid on the upholstery 3 together with air. The cleaning work is performed by sequentially moving the duct 2 over the covering material 3.

In this cleaning work, the conditions are listed in order as follows.

●Washing liquid Usually commercially available cleaning liquids are sufficient, but since the cleaning liquid is sucked in immediately after being sprayed, as will be explained later, you may use one with a slightly stronger cleaning power. Also, depending on the stain, water alone may be sufficient.

●Spraying of cleaning liquid The cleaning liquid is sprayed in a mist form with air.
It is also convenient for work. For this reason, a conventional spray gun 1 was used which can spray the cleaning liquid by jetting compressed air. Further, it is preferable to spray the cleaning liquid within as narrow a range as possible. This is to facilitate suction, which will be described later. Therefore, it is preferable that the pressure of the compressed air supplied to the spray gun 1 is not too high, and in this embodiment, the pressure is about 2 atmospheres. moreover,
The sprayed cleaning liquid must be prevented from penetrating inside the facing material 3. For this purpose, it is best to use compressed air of relatively low pressure as described above, and to spray the cleaning liquid in the form of a mist. In order to prevent the cleaning liquid from penetrating into the inside of the facing material 3, the inventor set the goal that the cleaning liquid is approximately 2/3 of the maximum thickness of the facing material 3.
It is assumed that the penetration has reached a level of .

●Amount of cleaning solution sprayed The amount of cleaning solution sprayed varies somewhat depending on the material of the covering material 3, but when cleaning the interior of a car that is mainly made of acrylic fabric, it is approximately 15~
20 cleaning solutions are used.

●Suction of sprayed cleaning liquid It is best to suction the cleaning liquid together with air, and it is also easy to do. Therefore, the above-mentioned suction duct 2 is for sucking air, and when sucking this air, it sucks the cleaning liquid together with the air. The suction of the cleaning liquid by the suction duct 3 is such that the cleaning liquid is absorbed into the surface material 3.
It needs to be completed before it penetrates inside, so it needs to be done with some force. Specifically, in this embodiment, the suction duct 2 is connected to the covering material 3.
The air flow velocity was set to be approximately 40 m/sec when brought into contact at an angle of 14.5° with respect to the air. Further, if the suction of air by the suction duct 2 is too strong, the covering material 3 will be damaged, so it is not preferable for the flow velocity to greatly exceed 40 m/sec.

●Friction of the facing material after spraying the cleaning liquid To rub the facing material 3 after spraying the cleaning liquid and before suctioning the cleaning liquid, use the brush 6 mentioned above (second
For example, a protrusion is provided at the tip of the spray gun 1, and this protrusion rubs the surface material 3 while the spray gun 1 sprays the cleaning liquid. It is better to do this.

The inventor also proposed a device in which the spray gun 1 and the suction duct 2 are put together in one box, and this box is moved onto the covering material 3, thereby spraying and suctioning the cleaning liquid at the same time. I am considering it. This is effective in that the cleaning work can be carried out with one hand and that the cleaning solution is not scattered to unnecessary areas.

(Effects) According to the above-described cleaning method, since the sprayed cleaning liquid is immediately removed by suction, there is almost no need to dry the facing material 3 after cleaning.
The work can be done in a shorter time than conventional cleaning work. In addition, since the cleaning liquid after being sprayed is immediately removed by suction, it does not scatter to the surrounding area and does not penetrate inside the facing material 3. There is no possibility that dirt such as dust that has been adsorbed or adhered to the surface of the covering material 3 rises to the surface. For this reason,
There is no need to wash dirt that has surfaced again after washing, which was a problem in the past. Further, according to such a cleaning method, since the cleaning liquid does not accumulate on the covering material 3, even when cleaning the covering material 3 located on the ceiling of the automobile shown in FIG. There is no dripping, and the cleaning work can be carried out in a comfortable condition.

Furthermore, if the surface material 3 is rubbed immediately after spraying the cleaning solution, it is possible to reliably remove dirt that could not be removed by spraying the cleaning solution alone.

(Summary) As detailed above, in the present invention, a cleaning liquid in the form of mist is sprayed onto the surface of the upholstery covering the surfaces of chairs, walls, etc. at a spraying pressure of about 2 atm, and adheres to the surface of the upholstery. At the same time, the attached cleaning liquid is suctioned together with air, thereby cleaning the surface of the covering material and simultaneously removing the cleaning liquid in a continuous manner. This makes it possible to efficiently wash the surface of the surface material even if it is vertical or uneven.The surface material dries quickly after washing, shortening the cleaning time, and excess cleaning solution is removed from the surrounding area. It is possible to propose a cleaning method that can prevent scattering. In addition, spraying atomized cleaning solution onto the surface of the upholstery that covers the surfaces of chairs, walls, etc. at a spray pressure of about 2 atmospheres and adhering it to the surface of the upholstery, and at the same time, spraying the cleaning solution onto the surface of the upholstery after the cleaning If the surface is rubbed and then the cleaning liquid is immediately sucked in together with the air, the surface of the covering material can be washed while being rubbed and at the same time the cleaning liquid is instantly removed, which is done continuously. The surface material can be easily and efficiently washed, and not only does it require almost no drying of the washing liquid, but also stains that are difficult to remove can be washed immediately.
