The top air box of the device consists of two parts. A part of the air supply boxes 206 are annularly distributed, and the air supply area is larger; the other part is a central air box 207, surrounded by an annular air box 206, located in the middle of the top of the apparatus, with a relatively small air supply area. The central air supply box 207 is provided with two air supply openings, the first air supply opening 201 is communicated with an air supply pipe of the normal-temperature air conditioner and is provided with a first electric air valve 204, and the second air supply opening 202 is communicated with an air supply pipe of the high-temperature circulating air heating device and is provided with a second electric air valve 205. The bottom of the annular air feeding box 206 is paved with normal temperature filtering top cotton, and the bottom of the central air feeding box 207 is paved with high temperature filtering top cotton. The annular air feed box 206 is relatively independent from the central air feed box 207.

A lifting closed structure is arranged below the top air feeding box and above the inner operation space of the chamber body along the projection edge of the central air feeding box. The structure is provided with four upright posts 102 which are arranged between the ceiling of the bottom surface of the top central air feeding box 207 and the indoor floor 3, are positioned at four corners of a rectangle where the central air feeding box 207 projects to the ground, and are provided with an electric roller shutter heat-insulating partition wall 101 between every two upright posts 102, so that the electric roller shutter heat-insulating partition wall can be lifted and dropped by remote control operation. When the electric roller shutter heat-insulating partition wall 101 is lifted, the electric roller shutter heat-insulating partition wall is hung below the central air supply box 207 in a rolling manner, does not occupy the lower operation space and does not influence illumination and sight; when the electric roller shutter heat-insulating partition 101 falls down, it encloses a relatively closed independent space in the lower portion of the central air-feeding box 207, and the independent space is also an independent air-feeding box corresponding to the upper central air-feeding box. When the paint spraying points are replenished, the electric roller shutter heat-insulating partition wall 101 does not fall, an operation room is a large space which is communicated with the operation room in an open mode, air-conditioning air is integrally supplied to the upper part, and air-conditioning air is supplied to the annular air-supplying box 206 and the central air-supplying box 207. When the whole car is dried, the electric roller shutter heat-insulating partition wall 101 falls down to seal the whole car in a space opposite to the space, and the upper center air feeding box corresponding to the space is internally provided with hot air for drying and heating.

Below the floor of the operating room is an exhaust bellows. The cabin floor 3 is laid from steel panels through which wind coming down from the top blow box will pass and leave the apparatus via the blow box. The exhaust bellows is also divided into two parts, one part is a whole vehicle drying exhaust bellows 303 of an area directly below the projection of the central air supply bellows 207, the other part is a paint spraying point supplementing exhaust bellows 304 of an area outside the projection area of the central air supply bellows 207, and the two parts are separated and not communicated. The whole car drying and air discharging box 303 below the projection of the central air feeding box 207 is communicated with the return air pipe of the high-temperature circulating air heating device, and the paint spraying point air supplementing and discharging box 304 is communicated with the equipment air discharging pipe. When the paint spraying points are replenished, the top part is integrally supplied with air, and the lower exhaust box only has the paint spraying points on two sides to replenish the exhaust bellows 304 to work; when the whole car is dried, the lower exhaust box only works with the middle whole car drying exhaust box 303.

When the spraying repair is carried out on the automobile body, the operation state of equipment under the spot repair function and the spraying and baking integrated function is consistent, at the moment, the first electric air valve 204 is opened, and the second electric air valve 205 is closed. The air conditioner supplies air to two areas (annular air supplying box and central air supplying box) of the top air supplying box simultaneously, the equipment exhaust fan operates, and the air supplied by the air conditioner is exhausted out of the equipment by the exhaust fan through the air box connected with the exhaust air pipe.

When the car body is dried, the operation difference between the spot repair function and the spraying and drying integrated function is large.

When the spot repair is dried, an operator uses an infrared baking lamp to locally bake a spraying area, and the air supply and exhaust process is similar to the spraying operation, but the air conditioner and the air exhaust machine can operate at a very low frequency, the air supply and exhaust route is the same as that of the spraying process, and the air quantity is greatly reduced.

When the whole car is dried, the electric roller shutter heat-insulating partition wall 101 falls down to seal the car body to be dried in an independent space, the first electric air valve 204 is closed, the second electric air valve 205 is opened, the air conditioner and the exhaust fan are closed, and the high-temperature circulating air heating device is started to operate. The hot air enters the central air feeding box 207 from the second electric air valve 205, heats the enclosed space where the vehicle body is located by hot air, and after the hot air contacts the vehicle body, the hot air enters the air returning pipe of the high-temperature circulating air heating device from the air discharging box below the enclosed space, returns to the heating device, is heated by the device and is then returned to the enclosed space where the vehicle body is located, and thus the hot air is repeatedly circulated until the baking of the paint film of the vehicle body is completed. In the baking process, the high-temperature circulating hot air is sealed in a relatively independent heat insulation space, so that the heat influence on the surrounding environment is greatly reduced. After baking, the heating device stops running, the second electric air valve 205 is closed, the first electric air valve 204 is opened, the electric roller shutter heat-insulating partition 101 is lifted, the air conditioner and the exhaust fan run, and the hot air in the original closed space is carried out of the equipment by the air conditioner.
