Description of the Related Art Various materials used outdoors such as metals and paints are deteriorated by various environmental factors such as light, rain, dew condensation, temperature and humidity. To accurately reproduce this deterioration, it is necessary to perform an "outdoor exposure test" in which the various materials are exposed to the outdoors for the period of use. Environmental factors are often different. Therefore, a test method in which a test corresponding to each environmental factor is sequentially performed by a test apparatus corresponding to each environmental factor, that is, a test method in which a light irradiation test, a salt spray test, a dipping test, a drying test, etc. are performed individually and in order.

Since it cannot be performed under various conditions that exert a large influence), deterioration (corrosion) of the sample could not be reproducibly accelerated. In order to eliminate such drawbacks, a so-called combined cycle test apparatus has recently been developed and used, which tests in one test tank while loading various environmental factors.

The apparatus disclosed in Japanese Patent No. 43579 has a structure in which the test tank 2 is divided into an air tank 47 for performing an irradiation test and a dipping tank 46 for performing a dipping test, and the dipping tank 46 is an entire rotating frame 15. The test tank 2 inevitably becomes large in size because it is necessary to have a depth to sink. For this reason, it is essential that various devices (fan 8, heater unit 6, cooler 5, refrigerator, humidifier 7, etc.) required for adjusting the temperature and humidity in the test tank 2 have a large capacity, and the manufacturing cost of the device is also high. It was high. Further, since the lifting device 48 for the rotating frame 15 is provided on the ceiling of the device, the device itself becomes large and the installation place is limited. Therefore, there has been a problem in the art to develop a device which is relatively small and has a low device cost and a limited installation place.

なっている。In this embodiment, as this cleaning mechanism, water is sprayed inside the immersion vat 24 around the vicinity of the upper edge of the immersion vat 24 so as to wash away the solution for immersion test adhering to the inside of the immersion vat 24. A cleaning pipe 43 to which a cleaning nozzle 32 is attached is provided. A cleaning pipe 44, which is a branch of the spray pipe 41 of (3), is connected to the cleaning pipe 43. An electromagnetic valve g is arranged in the middle of the pipe, and when cleaning the immersion vat 24, the electromagnetic valve e is closed and the electromagnetic valve g is opened. Further, unlike (3), the water after cleaning can be drained without collecting it in the pure water tank 30 by closing the electromagnetic valve f provided in the pipe connected to the drainage port 42 and opening the electromagnetic valve h. It is like this.

Distilled water may be used instead of pure water. Further, when the vertical movement device for the immersion vat 24 is provided, the immersion vat 24 may be moved downward so that the cleaning water is less likely to splash on the sample 14. For connection with the immersion butt 24, the spray pipe 39 and the cleaning pipe 43, a flexible corrosion resistant hose or the like is used in order to correspond to the vertical movement of the immersion bat 24.

つ装置の設置スペースの制約を受けにくくなった。[Effect] According to the apparatus of the present invention, the light irradiation test can be performed as well as the immersion test. As a part of the rotating sample is immersed in the immersion vat provided under the light source while rotating the sample, it is necessary to separate it into the air chamber for light irradiation and the immersion tank below it as in the conventional device. Therefore, the test tank can be made small, and it is not necessary to provide an elevating device for the sample, and the volume of the immersion bat can be made small. Therefore, since the device can be miniaturized, the manufacturing cost can be reduced and the installation space of the device is less likely to be restricted.
