Summary of the Invention

Problems to be Solved by the Invention

[0006] As mentioned above, the environment in which the air shower system is installed does not allow the bringing in of information terminals, making it difficult to easily obtain information such as earthquake early warnings and other information about natural disasters. Furthermore, because the air shower system is installed at the boundary between the cleanroom and the normal environment, the door on the cleanroom side may not be able to be opened or closed due to an interlock. In the event of a natural disaster, it is necessary to activate an emergency button or similar to open the door before evacuating. Moreover, in the event of a sudden major natural disaster, it is expected that users will panic and it will be difficult for them to act calmly.

[0007] The air shower device described in Patent Document 1 does not take into account responses to natural disasters.

[0008] The present invention aims to provide an air shower device that can notify people in enclosed environments such as air shower devices or clean rooms of the occurrence of a natural disaster such as an earthquake or tsunami, and can also secure evacuation routes. [Means for solving the problem]

When the communication terminal receives an earthquake early warning or tsunami warning, the control unit shall notify the surrounding area of ​​the occurrence of a natural disaster using the display unit and / or the audio output unit, and also the normal environment side and It is a closed space. This releases the interlock on the door to the cleanroom, ensuring an escape route. [Effects of the Invention]

[0010] According to the present invention, it is possible to receive emergency earthquake warnings and tsunami warnings from a carrier wireless network and to notify people in enclosed environments such as air showers or clean rooms of the occurrence of a disaster in advance.

[0011] Furthermore, in the event of a disaster, the interlock on the air shower system can be released, the lights can be turned on, and the air shower system can be used as an evacuation route.

[0012] Other issues, configurations, and effects not mentioned above will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

[Figure 6] This is a plan view showing an air shower device according to Embodiment 2 of the present invention. [Modes for carrying out the invention]

[0014] Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not to be construed as being limited to the embodiments described below. It will be readily apparent to those skilled in the art that the specific configuration can be modified without departing from the spirit or essence of the present invention. In addition, in each figure used to illustrate the embodiments, the same names and reference numerals are used for identical components whenever possible, and repeated explanations are omitted. [Examples]

[0015] Figure 1 shows a perspective view of an air shower device according to Embodiment 1 of the present invention, Figure 2 shows a plan view of the AA' cross section of Figure 1 seen from above, and Figure 3 shows a side view of the BB' cross section of Figure 1 seen from the side.

[0016] Inside the housing 10 that constitutes the air shower device 100, a fan motor 11 that sends out air and a HEPA filter 12 that creates clean air are provided. The clean air that has passed through the HEPA filter 12 is supplied as an air jet into the air shower chamber through air jet outlets 21 provided on the side surfaces and ceiling of the air shower chamber 20. Also, at the entrances and exits on the normal environment side and the clean room side, a door 13 and an interlock 14 that restricts the opening and closing of the door are provided. Further, lighting 15 that illuminates the air shower chamber 20 inside the housing 10 is provided. The fan motor 11, the interlock 14, and the lighting 15 are controlled by a control unit 16.

[0017] Inside the housing 10, a communication terminal 17 that can be connected to a carrier wireless network is provided. The communication terminal 17 is constantly connected to the carrier wireless network. Also, on the side surface of the air shower chamber 20, a speaker 18 that is a voice output unit and a display unit 19 that displays characters and the like are provided.

[0018] FIG. 4 shows a block configuration diagram of the electrical system of the air shower device of Example 1. When the communication terminal 17 connected to the carrier wireless network receives an emergency earthquake warning or a tsunami warning, it outputs a signal to the control unit 16. Then, the control unit 16 outputs a control signal to the fan motor 11, the interlock 14, and the lighting 15. Also, the control unit 16 sends an alarm signal to the display unit 17 that displays characters and the like and the speaker 18 that is a voice output unit.

[0019] FIG. 5 shows an operation flowchart of the air shower device of Example 1 of the present invention.

[0020] When an earthquake occurs, the Meteorological Agency detects the P wave of the seismic wave and issues an emergency earthquake warning before the S wave that causes strong shaking arrives. When the communication terminal 17 connected to the carrier wireless network receives this announcement, it transmits an emergency earthquake warning signal to the control unit 16 (S101). The same applies to the case of a tsunami warning.

[0021] When the control unit 16 receives an earthquake early warning signal in S102, it determines whether the air shower system is operating (S103). If the air shower system is operating, it forcibly stops its operation and resets all controls that are currently in operation (S104). In other words, it stops the fan motor 11 and turns off the lights 15. The control unit 16 then sends an alarm signal to the display unit and the audio output unit, and the display unit 19 and the speaker 18, which is the audio output unit, issue an alarm for the occurrence of a natural disaster (S105). If the air shower system is not operating in S103, the alarm for the occurrence of a natural disaster is issued without performing S104 (S105). By issuing an alarm before the arrival of the S wave, people in the air shower system 100 or the cleanroom 200 can prepare in advance for the earthquake. Then, in S106, all interlocks 14 on the entrance door 13 are released, making it possible to open the door 13 from the cleanroom side. Additionally, the lights 15 are turned on to make the area recognizable as an evacuation route. In this case, if the air shower system is equipped with an emergency power supply such as a UPS, it will remain an effective evacuation route even if the building experiences a power outage.

[0022] According to this embodiment, in the event of a natural disaster such as an earthquake or tsunami, the air shower device receives an emergency earthquake warning and tsunami warning using a carrier wireless network, and the air shower device issues a voice or text alert about the occurrence of the natural disaster, thereby informing people in enclosed environments such as the air shower device or a cleanroom of the occurrence of the natural disaster. Furthermore, the interlock of the air shower device can be released, and the lights can be turned on to secure evacuation routes. [Examples]

[0023] Figure 6 shows the air shower device of Example 2. The air shower device of this example is primarily used to alert people inside a clean room to the occurrence of a natural disaster.

[0024] As shown in the diagram, the speaker 18, which is the audio output unit, is attached to the clean room 200 side of the air shower device 100.

[0025] The communication terminal 17 receives the earthquake early warning signal, and the control unit 16 issues an alarm about the occurrence of a natural disaster to people in the cleanroom through the speaker 18, which is the voice output unit. Releasing the interlock 14 and turning on the lights 15 is the same as in Embodiment 1.

[0026] In addition to the speaker 18, which is the audio output unit, a display unit 19 may be provided on the outer surface of the air shower device 100 on the clean room side so that people inside the clean room can visually see the warning of a natural disaster.

[0027] According to this embodiment, by installing the speaker 18, which is the sound output unit, on the cleanroom side of the air shower device, it is possible to notify people inside the cleanroom of the occurrence of a natural disaster and to secure evacuation routes. Furthermore, by attaching the speaker 18, which is the sound output unit, to the air shower device, it is possible to create a cleanroom that can notify people of the occurrence of a disaster and secure evacuation routes simply by placing the unitized air shower device at the entrance of an existing cleanroom 200.

[0028] It should be noted that the present invention is not limited to the embodiments described above, and various modifications are included. For example, the embodiments described above are described in detail to make the present invention easier to understand, and are not necessarily limited to those having all the configurations described. Furthermore, it is possible to replace parts of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add configurations from other embodiments to the configuration of one embodiment. In addition, it is possible to add, delete, or replace parts of the configuration of each embodiment with other configurations.
