Description

Experiment Table Assembly {experiment table assembly}

The present invention relates to a bench assembly that can easily proceed with a chemical experiment using a variety of chemicals.

As a work bench for conducting chemical experiments using various chemicals in a laboratory or a laboratory, a test bench called a "fume hood device" is mainly used.

Briefly, the structure of the test bench includes a main body having an inner space with one surface opened, and an exhaust part formed to discharge various harmful gases generated in the inner space of the main body to the outside of the main body.

Particularly, the exhaust part is provided with an exhaust passage in a side wall surface above the bottom surface (working surface) of the main body of the main body or on the ceiling, and various harmful gases generated when the experiment is performed in the laboratory space. It is formed to be discharged in a so-called upward exhaust system, which is moved upward from the bottom surface side.

That is, according to the structure of the test bench, the chemical experiment can be carried out with various chemicals on the bottom surface of the inner space, and the toxic gas generated at this time, various harmful gases such as odor, chemical vapors, etc. It can be discharged (removed) by upward exhaust from the internal space.

As described above, when various chemical experiments are carried out inside the bench, it is very important to quickly discharge (remove) various harmful gases generated in the internal space to the outside quickly by driving the exhaust unit.

However, there are various problems in the structure of discharging various harmful gases generated during the experiment in an upstream exhaust manner as in the conventional experiment table.

In other words, the upstream exhaust gas discharges various harmful gases generated on the floor (working surface) gradually upward by forming an upward airflow in the interior space of the bench, so as to quickly discharge (remove) harmful gases generated in the internal space. it's difficult.

In addition, if the harmful gas is not quickly discharged, it is difficult to expect satisfactory exhaustion efficiency and operational stability since the harmful gas stays long in the space inside the experiment table and can easily flow out to the outside through the opening of the inner space.

Moreover, when noxious gas flows out through the opening of the inner space, the experimenter may inhale the gas and cause a serious safety accident.

In addition, the upward exhaust method, since it is difficult to smoothly remove various solid fine particles generated in the interior space of the experiment table during the exhaust of harmful gas, there is a problem that the internal space is easily contaminated.
