[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an environmental testing machine (hereinafter simply referred to as a testing machine) used for research and development tests in various industrial fields.

[0002]

[Prior art]

 As shown in FIG. 3, the conventional tester partitions the test tank 2 surrounded by the heat insulating layer 1 and a part of the test tank 2 into a fan for stirring inside the tank, a heater, a cooler, a humidifier, and the like. An air conditioning equipment room 3 in which the equipment is set, a machine room 4 in which a refrigerator or the like is installed, a control room 5 for controlling the equipment is provided next to the test tank 2, and a heat insulating door 6 is provided in front of the test tank 2. There is.

An observation window 7 for observing the inside of the tank is provided on the heat insulating door 6, and an operation panel 8 is attached to the front surface of the control room 5.

[0004]

[Problems to be solved by the device]

 In the conventional testing machine, the observation window 7 is provided in the heat insulation door 6, and the operation panel 8 is provided in front of the control room 5, so that the control room 5 and the test tank 2 are provided side by side. Since it is necessary, the plane area of the testing machine becomes large, and the installation site of the testing machine needs to be wide, and since the observation window 7 and the operation panel 8 are located apart from each other, It is inconvenient to operate while observing the inside of the test tank 2. Furthermore, the design is not organized.

An object of the present invention is to provide a testing machine which has a small plane area, is easy to operate while observing, and has a cohesive design.

[0006]

[Means for Solving the Problems]

 An observation window and an operation panel will be installed close to or in contact with the heat insulation door provided in front of the test tank surrounded by the heat insulation layer of the tester. Alternatively, the observation window and the operation panel are attached to the same frame, and the frame is attached to the heat insulation door attached to the front of the test tank surrounded by the heat insulation layer.

【Example】

 An embodiment of this invention will be described with reference to the drawings. A machine room 4, a control room 5, and a water supply tank 9 are provided below a test tank 2 having a heat insulating door 6 surrounded by a heat insulating layer 1 on the front surface. An intake hole (not shown) is provided on the front surface of the machine room 4, and an exhaust hole (not shown) is provided on the rear surface.

The observation window 7 and the operation panel 8 are housed in one frame 10, and the frame 10 is attached to the heat insulating door 6.

As shown in FIGS. 2A and 2B, the observation window 7 and the operation panel 8 may not be housed in a single frame 10, but may be provided vertically, horizontally, or in close proximity to each other. .

The operation panel 8, the control room 5, the machine room 4, and the air conditioning equipment room 3 are connected by wiring (not shown).

Behind the test tank 2, a piping and a machine room 11 for the refrigerant gas and water are provided.

When using this tester, the object to be tested is housed in the test tank 2, and the operation panel 8 controls the temperature, humidity, light amount, etc. in the test tank 2, and the object to be tested is observed from the observation window 7. Visually check the condition of the test object. A sensor may be installed in the test tank 2 to notify the change of the object under test to the outside.

[0013]

[Action and effect]

 The heat insulation door is equipped with an observation window and an operation panel so that the space of the heat insulation door can be effectively used, and the effective width dimension of the test tank is added to the width direction of the testing machine by the thickness of the heat insulation tank. Allows design with the minimum required dimensions and saves installation space. The following table compares the sizes of the conventional tester and the tester according to the present invention.

Since the observation window and the operation panel are in contact with or close to each other, it is possible to operate while observing the object under test in the test tank, and at that time, the letters and numerical values on the operation panel can be closely located. You can check it and do not misunderstand.

In the conventional testing machine, since the operation panel and the control room are integrated and mounted above the machine room, the semiconductor section of the operation panel is exposed to dust and hot air blown from the machine room. , It was necessary to attach a shield plate for protection, but in the tester according to this invention, the operation panel and the control room are separated, connected by wiring, and the operation panel is attached to the heat insulation door. The semiconductor part is not affected by the machine room, and there is no need to attach a shield plate.

The observation window and the operation panel can be provided at positions where operation and observation are excellent.

A cohesive and clean design is obtained.
