[Problem that the idea aims to solve]

However, this conventional booth has a high illuminance that can be obtained from the lighting fixtures on the top of the side wall. The lighting fixtures at the bottom of the front and side walls are unevenly distributed around the steps of the repaired vehicle, and The optical axis of these lights is set horizontally, so the light is uniform across the sides of the vehicle being repaired. Illuminance could not be obtained and it was not possible to accurately check the paint condition.

0004 In addition, conventional booths have vertical side walls on both sides of the room, so they have a large floor space. It takes up a lot of space, requires a large installation space, and requires an exhaust groove on the floor. This increases the width of the exhaust fan, which increases the capacity of the exhaust side blower and increases equipment costs. The airflow inside tends to stagnate around the bottom of the side wall, making it difficult to efficiently exhaust paint mist to the outside. There were problems such as not being able to get out.

[0005] This invention solves these problems and improves the quality inside the paint booth with a simple configuration. In addition to providing lighting, the installation space of the painting booth can be made more compact and equipment costs can be reduced. Automotive product that reduces paint mist and efficiently discharges paint mist to the outside. The purpose is to provide painting booths.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. is a painting booth installed on the floor 2 of an automobile repair shop, and the interior cross section is shown in the figure. It is formed into a substantially rectangular shape as shown in FIG. The shaped walls 4 and 5 are formed.

[0008] The upper portions of the upper slanted walls 4, 4 are bent inward after protruding upward, and are connected to the coating booth 1. A ceiling wall 6 is formed, and a filter 7 is provided between the upper edges of the upper slanted walls 4, 4. The ceiling wall 6 and the filter 7 partition a ceiling chamber 8, and a filter is provided in the chamber 8. A ventilation duct 9 communicating with an air supply device (not shown) is connected.

[0009] The lower ends of the lower slanted walls 4, 4 are located inside the side walls 3, 3, and are partitioned by them. The floor width of the painting booth 1 is made narrower than the floor width divided by the side walls 3, 3. Upper and lower lights 10 and 11 for indoor lighting are installed on the outer surfaces of these upper and lower slanted walls 4 and 5. ing.

0010 The upper and lower lights 10 and 11 are composed of one or more rod-shaped fluorescent lamps, which are painted. They are arranged parallel to the floor surface 2 along the depth direction of the installation booth 1, and their optical axes are It is installed toward the approximate center of the mounting booth 1.

[0011] An exhaust groove 12 that communicates with an exhaust system (not shown) is provided on the floor 2 of the painting booth 1. A grating 13 is installed on the edge of the opening of the groove 12, and this grating 1 A repair vehicle 14 is allowed to enter on top of the vehicle. In the figure, reference numeral 15 indicates stored water stored at the bottom of the exhaust groove 12.

[Effect]

The automotive paint booth configured in this way is similar to the conventional paint booth shown in Figure 2(b). The lower ends of the side walls 3, 3 of the base are bent inward to form lower oblique walls 5, 5, The lower ends of the inclined walls 5, 5 are arranged on the floor surface 2, and the lower ends of the inclined walls 5, 5 are placed on the floor surface 2. The configuration is extremely simple as all you have to do is attach the lights 11 and 11, and it is easy to manufacture. obtain.

[0013] Moreover, due to the lower slanted walls 5, 5, the width of the floor surface of the painting booth 1 is reduced by the side walls 3, 3. The width is narrower than the conventional partitioned floor width, and the floor space can be reduced accordingly. The installation space of the painting booth 1 can be made more compact.

[0014] As the floor space of the painting booth 1 became narrower, an exhaust groove was formed on the floor surface 2. The opening width of 12 is also narrower, and the opening area is smaller than the conventional one. , reduce the capacity of the exhaust device that sucks the air in the exhaust groove 12 and exhausts it to the outside; Equipment costs can be reduced accordingly.

[0015] Next, using such a painting booth 1, paint the repaired vehicle 14 that has entered the room. When drying, the upper and lower lights 10 and 11 are turned on, and the air supply and exhaust system is activated. For example, as shown in Figure 1, air is supplied from above the painting booth 1, and paint mist is generated. The contained air moves to the exhaust groove 12 and is exhausted outside the room via the exhaust device.

[0016] In such painting work, the inside of the painting booth 1 is equipped with upper and lower lighting 10 as described above. , 11, and their optical axes are set toward the approximate center position inside the painting booth 1. It is.

[0017] Therefore, unlike in the past, the lower lighting is unevenly placed at a specific lower position on the side wall. The illuminance inside the painting booth 1 is lower than that in the case where the optical axes are is uniform, and the distance from the upper and lower lights 10, 11 to the repair vehicle 14 is approximately equal. By setting the distance, it is possible to prevent variations in illuminance on the surface of the repaired vehicle 14, and Since the formation of shadows in step 14 can be prevented, the coating state can be accurately and easily confirmed.

[0018] Moreover, inside the painting booth 1, reflected light can also be obtained from the lower slanted walls 5, 5. Therefore, the illuminance on the surface of the repaired vehicle 14 is improved compared to the conventional one, and the above-mentioned accuracy is achieved. Facilitate verification work.

[0019] In addition, the airflow inside the painting booth 1 in this case is as shown in Fig. 2(a). The airflow moves downward along the inner surfaces of the upper diagonal wall 4, side wall 3, and lower diagonal wall 5, and The paint moves smoothly without stagnation in these areas and is sucked into the exhaust groove 12. To reliably and efficiently exhaust air containing mist etc. to the outside.
