Claims

[Scope of Claim for Utility Model Registration] 1. An airtight chamber whose outer peripheral wall is covered with a heat insulating material made of a transparent material such as glass or plastic, and at least one part of this airtight chamber is provided with an opening/closing door that can communicate with the outside. A lighting lamp was installed around the outside of the area other than the area where the door is located, and along with the lighting equipment, equipment such as a heater, cooler, humidifier, circulation fan, etc. was installed to create the desired weather conditions in the airtight room. In an artificial weather device, the door consists of an outer door and an inner door, and the outer door has a small hole for supplying air, and the inner door is large enough to allow a hand to be inserted into the airtight chamber during work. A biohazard device characterized in that a through hole is provided in the airtight chamber, an exhaust fan is provided to maintain the pressure inside the airtight chamber at negative pressure at all times, and a filter is provided to filter the air exhausted by the exhaust fan. Artificial weather equipment for growing plants. 2. The artificial weather device according to claim 1, further comprising a filter for filtering air flowing in through the air supply small hole. 3 When the outer door and inner door are closed, the exhaust fan is operated at low speed and the circulation fan is activated. When the outer door is open and the inner door is closed, the exhaust fan is operated at medium speed and the circulation fan is activated. 3. The artificial weather device according to claim 1, further comprising a control member for controlling the exhaust fan to be operated at high speed when both the outer door and the inner door are open, and to stop the operation of the circulation fan.
