DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition for partitioning an office space, and an apparatus for cleaning a cloth for covering an indoor wall or the like.

[0002]

2. Description of the Related Art Conventionally, cleaning of a floor or a carpet laid on the floor is performed by mechanical agitation using a rotating brush device while spraying washing water onto the floor or the carpet.

[0003]

[0005] By the way, in a partition for partitioning an office space, and in an indoor wall, a vertical surface of an indoor wall surface such as a metal panel, a wooden panel, a resin panel, and a mortar / wall is decorated. Some are covered with a cloth for the purpose of noise reduction and the like. In FIG. 6, an “elevated base 50 made of a rigid material,
The cloth 51 covering the upright surface of the upright substrate 50 "is illustrated.

The above-described rotary brush device is not suitable for cleaning such a "cloth for covering an upright substrate made of a rigid material" for the following reasons.

First, the rotating brush device only disperses dirt on a carpet or the like to make it less noticeable, but does not remove dirt from the object to be cleaned. Therefore, the cleaning effect is unsatisfactory, unsanitary, and causes deterioration of the cloth.

Further, mechanical agitation by a rotating brush device fuzzes a cloth (fabric) and causes severe deterioration of the cloth. (A large rotating brush device has been used in the past because a carpet or the like that originally has hairs has little effect.) Use a cloth or a cloth soaked with detergent to clean it. Rubbing the surface is also conceivable.
However, this has the problem of deteriorating the cloth to be cleaned due to friction and the problem that a considerable amount of dirt remains in the cloth to be cleaned.

[0007] Further, with respect to this kind of article, there has been proposed an apparatus for sucking and removing residual detergent and dirt components while spraying detergent and then washing water (Japanese Utility Model Application Laid-Open No. 56-1).
No. 16950). This kind of article has water resistance, and because the jetted water can pass to the back,
A large amount of washing water is sucked while being sprayed on the cloth, so that a so-called rinsing action can be performed. By this rinsing action, residual detergent and dirt components are removed. However, in the case of “cloth covering a three-dimensional base made of a rigid material” as shown in FIG.
Since the cloth is directly bonded with an adhesive, there is a problem that the cloth is peeled off when washed with a large amount of water. Furthermore, since these cloths 51 are attached to the rigid three-dimensional substrate 50, when washing with water, water cannot penetrate the cloths, and a sufficient rinsing action cannot be performed.

In many cases, human hands come into contact with cloth such as a partition or a wall. Therefore, hand stains and oils and fats adhere to the cloth, and an oil film is formed on the surface of the cloth. This oil film cannot be easily removed by washing with a normal detergent, for example, a neutral detergent. When the oil film is dried in a state where the oil film cannot be completely removed, the oil film is diffused to form a so-called ring-shaped spot having an irregular uneven contour. The ring jig impairs the aesthetics of the partition or the like, and causes complaints from users.

Further, the above-mentioned known cleaning apparatus is designed for cleaning a bed such as bedding and a carpet or an article laid on the floor. Therefore, a suction port is attached to a tip of a long and hard suction pipe. In the case of cleaning the surface of a three-dimensional substrate such as a partition, there is a disadvantage that the usability is extremely poor. For the reasons listed above, at present, there is no method or apparatus suitable for cleaning “cloth covering a three-dimensional substrate made of a rigid material” such as a partition or a wall.

According to the present invention, there is provided a cleaning apparatus capable of cleaning a cloth covering a three-dimensional base surface made of a rigid material such as a partition or a wall without deteriorating the cloth surface and having a high cleaning effect. The first purpose is to do so.
In the present invention, the cloth covering the three-dimensional base surface made of a rigid material such as a partition or a wall can be efficiently washed,
In addition, a second object is to provide an easy-to-use cleaning device at low cost.

[0011]

In order to achieve the above object, the present invention is configured as follows. The cleaning apparatus according to the present invention is configured to spray a detergent aqueous solution onto a cloth covering an upright substrate made of a rigid material, and suck and remove the detergent sprayed on the cloth by the detergent spraying means together with a dirt component. In a cleaning apparatus including a suction unit, an operator grips a flexible hose connected to a detergent pumping unit of the detergent spraying unit and a flexible hose connected to a suction negative pressure unit of the suction unit. And a lever for controlling the injection of the detergent is provided on the grip portion, while being connected to the detergent injection nozzle and the suction nozzle provided on the grip portion for performing the operation. Further, the cleaning device of the present invention is characterized in that the injection port of the detergent injection nozzle is formed in a slit shape. In the cleaning device of the present invention, the cleaning effect can be further enhanced by combining with the pretreatment agent spraying device. That is, in many cases, an oil film such as hand scales and oils and fats is formed on the surface of the cloth that covers the upright base made of a rigid material such as a partition or a wall. By spraying a pretreatment agent containing an organic solvent or the like that destroys the oil film on these oil films, the oil film is broken, and the cleaning effect of the aqueous detergent in the next step can be enhanced.
