  Hereinafter, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described using the drawings.

First Embodiment
FIG. 1 is a front view showing an entire configuration of a first embodiment of the device containment device of the present invention. FIG. 2 is a left side view showing the device containment device 1 shown in FIG. FIG. 3 is a right side view showing the device containment device 1 shown in FIG. FIG. 4 is a plan view showing the device containment device 1 shown in FIG.

  The device containment apparatus 1 shown in FIGS. 1 to 4 preferably accommodates the target device M in the work space G, and passes air with a low air flow draft when performing work and experiments using this device M. Low air flow draft chamber. The equipment containment device 1 is used by an operator in the work space G in the storage to perform the required work or experiment using the equipment M of interest.

  The target device M to be contained in the work space G of the device containment device 1 includes various experimental devices, an analyzer for analyzing an object to be analyzed, or a manufacturing device. The apparatus containment apparatus 1 is, for example, a spray dryer for pulverizing a sample using an apparatus M, a manufacturing operation of a drug, and an aseptic operation of a sample such as a microorganism by a worker such as a researcher or an experimenter. It is used to perform chemical experiments and the like.

  In recent years, from the viewpoint of energy saving, a device capable of operating with an exhaust air flow rate smaller than the conventional air flow rate is required for the apparatus containment device 1. Such an apparatus containment device 1 is generally referred to as a "low air flow draft chamber" or a "low air flow fume hood". The air volume in the apparatus containment device 1 is, for example, 50% to 60% of the air volume in a normal draft chamber, and it is possible to contain harmful gas, powder and the like in the storage.

  As the apparatus containment device 1, preferably, for example, a constant air flow type can be adopted in which the exhaust air flow is always constant (CAV: constant air flow control). However, the device containment apparatus 1 is not limited to this, and may be a variable air volume type that combines the VAV (variable air volume control) method with this constant air volume type from the viewpoint of further energy saving. .

  The apparatus containment apparatus 1 externally operates the atmosphere of the internal work space G so that the worker is not affected by the work or the harmful substance when processing the work in the work or experiment in the internal work space.
