BACKGROUND OF THE INVENTION
The present invention relates to a ventilation system for circulating indoor and outdoor air in a building.
[0002]
[Prior art]
For example, in a building such as a high-rise apartment, when the entrance door is opened and closed, if there is a pressure difference between the interior and the exterior of the building, the entrance and exit of the entrance door may be hindered. For example, if a strong wind is blowing toward the entrance door or the indoor fan is operated to exhaust the indoor air to the outside of the building, the indoor pressure becomes negative and the outdoor The atmospheric pressure becomes positive, and the entrance door is difficult to open due to a difference in atmospheric pressure inside and outside the room. In order to avoid such a door opening / closing failure, it is necessary to appropriately distribute the air inside and outside the room in order to reduce the pressure difference between the room and the room.
[0003]
By the way, conventionally, in order to ventilate between the room and the outside, an air supply port through which air flows is provided near the entrance door, or air in the room and outside is circulated using the space behind the ceiling. It has been done. And the atmospheric | air pressure difference of an indoor and an outdoor is relieve | moderated by the circulation | circulation of such indoor and outdoor air.
In addition, the knob and key mechanism of the entrance door is provided with an opening and a pressure adjustment door that opens and closes the opening, and by opening and closing the pressure adjustment door in conjunction with the operation of the knob, There has also been proposed a technique for reducing air pressure difference between indoors and outdoors by circulating air.

[0017]
As shown in FIG. 3, the partition wall 170 that partitions the toilet room 164 and the washroom 168 has a ventilation space 171 extending in the vertical direction therein.
The ventilation space 171 and the space behind the ceiling communicate with each other, and at the lower end of the partition wall 170, a wall air supply port 170A communicating with the ventilation space 171 is provided on each side of the toilet room 164 and the bathroom 168. It is arranged to face.
[0018]
The corridor room 118 is provided connected to the entrance opening 115 and constitutes a part of a space communicating between the entrance opening 115 and the balcony opening 123. The opening / closing door 120 is disposed at an intermediate position of the hallway chamber 118 so that a windbreak chamber is formed between the door opening 115 and the entrance opening 115.
[0019]
A first opening 139 is disposed in the entrance door 115 so as to communicate the outdoor and the windbreak chamber. The first pressure adjusting door 138 is provided to open and close the first opening 139, and the amount of air flowing through the first opening 139 by adjusting the opening area of the first opening 139 is within a predetermined range.

Is configured to be within a predetermined range
The entrance door 115 and the open / close door 120 are provided with a door closer (not shown) so that the door is always closed.
[0020]
Next, a normal ventilation operation with the above-described configuration will be described.
When strong wind or the like is not generated, the air supply shutter 133 of the second outdoor air supply port 132 is kept open.
Therefore, when air is blown in the direction from the entrance side to the balcony side, the air flows from the first outdoor air supply port 130 to the first space, the ventilation opening 126, the second space, and the second outdoor air supply. It circulates through a route called a mouth 132. Then, as indicated by arrows in FIG. 3, the air flows from the first space to the living rooms 154 and 156 via the first indoor air supply port 134 and from the second space via the second indoor air supply port 136. It distributes to the living room 158, the kitchen 160, the toilet room 164, the bathroom 162, and the washroom 168.
When air is blown in the direction from the balcony side to the entrance side, the air is supplied from the second outdoor air supply port 132 to the second space, the ventilation opening 126, the first space, and the first outdoor air supply. It circulates through the path | route called the opening | mouth 130, and distribute | circulates to the living rooms 154 and 156 via the 1st indoor air supply opening 134 from the 1st space similarly to the above, and passes the 2nd indoor air supply opening 136 from the 2nd space The living room 158, the kitchen 160, the toilet room 164, the bathroom 162, and the washroom 168 are distributed.
Therefore, according to the ventilation system according to the present embodiment, efficient ventilation is always performed indoors and outdoors using the flow of natural air, without opening the entrance door or balcony door or operating the ventilation fan. It becomes possible. At this time, air can be circulated from either the balcony side or the entrance side toward the lower side from the higher atmospheric pressure side.
[0021]
Further, since air flows from the wall air supply port 170A disposed at the lower end via the ventilation space 171 inside the partition wall 170 to the toilet room 164 and the washroom 168, normal ventilation suddenly occurs. A sufficient amount of air flows through difficult areas. The wall air supply port 170A is preferably provided in a place where ventilation is not sufficiently performed, for example, in a storage box or a closet, in order to improve ventilation.
[0022]
Further, the amount of air flowing through each of the living rooms 154, 156, 158, the toilet room 164, the bathroom 162, and the washroom 168 is arbitrary by adjusting the opening area of the ventilation pressure adjusting door 128 provided in the ventilation opening 126. Can be adjusted. The opening area of the ventilation pressure adjusting door 128 can be adjusted as follows, for example. That is, an opening for operation is provided at a location on the indoor ceiling wall 108 near the location where the ventilation pressure adjustment door 128 is disposed, and the opening area of the ventilation pressure adjustment door 128 is manually adjusted from the opening. Should be done.
[0023]
On the other hand, when a strong wind occurs due to weather such as a typhoon, a control operation as shown in the flowchart of FIG. 4 is performed.
First, when a resident blows strong wind from the open second outdoor air supply port 132, noise is generated from the first and second indoor air supply ports 134 and 136, or cold air enters the living room. It is determined whether or not there is a trouble such as (step S10).
The resident is not required to operate the air supply shutter operation switch 206 if it is determined that there is no particular problem. As a result, the control means 200 holds the air supply shutter 133 of the second outdoor air supply port 132 in an open state (step S18), and proceeds to step S10.
If there is a problem caused by a strong wind, the resident operates the air supply shutter operation switch 206 to close the air supply shutter. The control means 200 gives a control signal to the air supply shutter 133 based on the operation signal given from the air supply shutter operation switch 206 and closes it (step S12). Then, the timer means 208 is activated by giving an activation signal.
Next, the control unit 200 determines whether or not the ventilation fan is activated based on the detection signal from the ventilation fan operation detection unit 202 of the ventilation fans 142 and 144 (step S14). When it is determined that at least one of the ventilation fans 142 and 144 is operating, a control signal is given to the air supply shutter 133 of the second outdoor air supply port 132 to open it (step S18), and the process proceeds to step S10.
Therefore, by guiding the outdoor air from the second outdoor air supply port 132 to the living room via the second indoor air supply port 136, the ventilation amount by the ventilation fans 142 and 144 is secured, and an excessive load is applied to the ventilation fans. The problem can be prevented.
[0024]
On the other hand, when it is determined in step S14 that both the ventilation fans 142 and 144 are inactive, the closed state of the supply shutter 133 of the second outdoor supply port 132 is maintained. Then, when the timer means 208 activated in step S12 gives a timing signal indicating that a predetermined time (for example, 8 hours) has been counted to the control means 200 (step S16), the control means 200 causes the second outdoor air supply port 132 to be measured. The air supply shutter 133 is opened by giving a control signal (step S18), and the process proceeds to step S10. As a result, even when the air supply shutter 133 of the second outdoor air supply port 132 is closed, the indoor / outdoor ventilation operation is automatically started by opening the second outdoor air supply port 132 after a predetermined time has elapsed. can do.
[0025]
Next, the ventilation operation at the time of opening and closing the entrance door with the above-described configuration will be described.
As described above, by providing the opening / closing door 120 at an intermediate position of the hallway chamber 118, a windbreak chamber is formed between the opening / closing door 120 and the entrance opening 115. A first pressure adjustment door 138 is disposed in the first opening 139 of the entrance door 116, and a second pressure adjustment door 140 is disposed in the second opening 141 of the opening / closing door 120.
Therefore, even when air blows against the entrance door 116 and the outdoor side of the entrance opening 115 side has a positive pressure and the room has a negative pressure, the opening / closing door 120 is closed and the corridor chamber 118 has a wind vent room. By being formed, the pressure difference between the inside and outside of the room is relieved by the action of the windbreak chamber, so that the pressure applied to the entrance door 116 is reduced, and the entrance door 116 can be easily opened.
Further, by adjusting the opening areas of the first and second pressure adjusting doors 138 and 140, the amount of air passing through the first and second opening portions 139 and 141 is adjusted, and The atmospheric pressure difference can be adjusted.
Note that the second opening 141 and the second pressure adjustment door 140 can be omitted if sufficient air can flow between the hallway chamber 118 and the living room 158 at the gap between the opening and closing door 120.
[0026]
By the way, since the ventilation opening 126 is provided in the partition wall 112, when the entrance door 116 is opened, the outdoor air pressure on the balcony side is changed to the second outdoor air inlet 132, the first and second spaces on the ceiling. The air pressure in the corridor chamber 118 is affected via the first indoor air supply port 134 and the doors 154A and 156A of the living rooms 154 and 156, and there is a possibility that the air pressure relaxation action by the wind vent room may be hindered.
For this reason, when the control means 200 receives the detection signal that detects the opening operation of the entrance door 116 from the entrance door opening detection means 202, the control means 200 is for ventilation for a predetermined time (time required for opening the entrance door 116). A control signal is given to the pressure adjustment door 128 to close it.
As a result, the outdoor air pressure on the balcony side is prevented from affecting the air pressure in the corridor chamber 118, the air pressure is reliably reduced by the windbreak chamber, and the entrance door 116 can be easily opened. ing.
[0027]
Further, when the ventilation fans 142 and 144 are activated, as described above, the air supply shutter 133 of the second outdoor air supply port 132 is opened, so that outdoor air passes through the second space behind the ceiling. And since it distribute | circulates from the 2nd indoor air supply opening 136, it is prevented that the indoor becomes a negative pressure by the exhaust operation by the ventilation fans 142 and 144, and the entrance door 116 becomes difficult to open.
[0028]
In addition, when the atmospheric pressure difference between the high and low floors is different between the high floor and the low floor as in a high-rise apartment, the ventilation volume can be adjusted to an appropriate value by adjusting the opening area of the ventilation pressure adjustment door 128. Can be adjusted. Similarly, by adjusting the opening area of the first and second pressure adjusting doors 138 and 140, the pressure difference between the windbreak chamber formed in the hallway chamber 118 and the outside on the entrance opening 115 side is appropriately adjusted. Can be adjusted to any value.
[0029]
In the above-described embodiment, the timer unit 208 is provided separately from the control unit 200. However, the timer unit 208 may be configured by hardware such as a timer IC included in the control unit 200, or the control unit. You may comprise by the software implement | achieved by 200 control programs.
Further, there is known an air supply shutter that is configured in combination with timer means and configured to perform an opening / closing operation based on a time measuring operation of the timer means. It may be used. In other words, the air supply shutter 133 is activated by the control of the control means 200 to activate the timer means, and the air supply shutter 133 opens itself when the timer means times a predetermined time.
