Description

The present invention relates to a ventilation structure of a perimeter space including a ventilation compartment that partitions an indoor space and a perimeter space, and an exhaust portion that takes in and exhausts the perimeter space.

Here, the "perimeter space" means an indoor space such as a window or a wall that is easily affected by outdoor conditions such as sunlight and outside temperature in the indoor space of a building.
Therefore, the air in the perimeter space affected by the outdoor conditions such as the outside air temperature flows into the indoor space side while the warm air rises in the summer and the cold air falls in the winter, for example. There are adverse effects such as deterioration of comfort.

Therefore, conventionally, a roll screen that separates the indoor space and the perimeter space and an exhaust fan that takes in and exhausts the inside of the perimeter space are provided, and the indoor space and the perimeter space are fully closed by raising and lowering the roll screen. By winding it up a little, it can be switched to the lower ventilation state where the lower part communicates, and the exhaust fan can be switched between the upper intake state where the intake air is taken from the upper cross air passage and the lower intake state where the intake air is taken from the lower cross air passage. A ventilation structure for the perimeter space has been proposed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2001-303704

According to the prior art described in Patent Document 1, in summer, warm air in the perimeter space affected by outdoor conditions is taken in from above, and cold air in the indoor space flows into the perimeter space from below. Therefore, the entire perimeter space is ventilated with an ideal air flow.
However, in winter, although the cold air in the perimeter space affected by the outdoor conditions is taken in from below, the roll screen is fully closed, so the warm air in the indoor space is on both sides and above the roll screen. It will flow into the perimeter space through the gap (see paragraph [0019] of the specification), and the entire perimeter space is not always ventilated with an ideal air flow. That is, a part of the cold air in the perimeter space may remain above the perimeter space and stay there, and the cold air may flow into the indoor space from both sides of the roll screen.

The present invention focuses on such conventional problems, and an object of the present invention is to ensure that the entire perimeter space is always ventilated with an ideal air flow to maintain the comfort of the indoor space. The purpose is to provide a ventilation structure for possible perimeter spaces.

The first characteristic configuration of the present invention is a ventilation structure of a perimeter space including a ventilation compartment that partitions an indoor space and a perimeter space, and an exhaust portion that takes in and exhausts the perimeter space. The compartment is configured to be freely switchable between an upper ventilation state having a ventilation portion between the indoor space and the perimeter space above the ventilation portion and a lower ventilation state having a ventilation portion below the interior space, and the exhaust portion is an intake portion from the perimeter space. A first mode in which the ventilation compartment is in the upper ventilation state and the exhaust portion is in the lower intake state, and the ventilation is configured so as to be freely switchable between an upper intake state having an upper portion and a lower intake state having a lower portion. The point is that the compartment is freely switchable to the second mode in which the lower ventilation state and the exhaust portion are the upper intake state.

According to this configuration, for example, when the outside air temperature is extremely low compared to the indoor temperature such as in winter, the mode is switched to the first mode, and the outside air temperature is extremely high compared to the indoor temperature such as in summer. In that case, it is possible to switch to the second mode.
Then, in the first mode, the ventilation compartment is in the upward ventilation state and the exhaust unit is in the downward intake state, and the cold air in the perimeter space affected by the outdoor conditions is taken in from below, and the warm air in the indoor space is taken in. Since it flows into the perimeter space from above, the entire perimeter space is ventilated by an ideal air flow in which cold air descends.
Further, in the second mode, the ventilation compartment is in the downward ventilation state and the exhaust part is in the upward intake state, the warm air in the perimeter space affected by the outdoor conditions is taken in from above, and the cold air in the indoor space is taken in. Since it flows into the perimeter space from below, the entire perimeter space is ventilated by an ideal air flow in which warm air rises.
As a result, in both the first mode and the second mode, the perimeter space is always reliably ventilated by the ideal air flow, and the comfort of the indoor space is maintained.

In the second characteristic configuration of the present invention, the ventilation compartment is provided with a non-breathable compartment that can be repositioned in the vertical direction, and the non-breathable compartment is repositioned downward to bring the non-breathable compartment into the upward ventilation state. The point is that the position is changed upward to switch to the downward ventilation state.

According to this configuration, the ventilation compartment is provided with a non-breathable compartment that can be repositioned in the vertical direction, and the non-breathable compartment is switched between an upward ventilation state and a downward ventilation state by repositioning the non-breathable compartment. Therefore, the structure is simple and the switching operation is easy. For example, automation using an electric actuator is also easy.

In the third characteristic configuration of the present invention, the ventilation compartment is provided with a breathable compartment that can be repositioned in the vertical direction, and the breathable compartment is repositioned upward to be in the upward ventilation state and downward. The point is that the position is changed to switch to the downward ventilation state.

According to this configuration, in addition to the non-breathable compartment described above, the ventilation compartment is provided with a breathable compartment that can be repositioned in the vertical direction, and the ventilation compartment is repositioned to provide upward ventilation. Since the state can be switched between the upper ventilation state and the lower ventilation state, the perimeter space is covered by the non-breathable compartment and the breathable compartment when viewed from the indoor space side in both the upper ventilation state and the lower ventilation state.
Therefore, when viewed from the indoor space side, the perimeter space can be covered with the ventilation compartment, and the ventilation compartment can be made to have a neat appearance. For example, if the non-breathable compartment is made of Japanese paper and the breathable compartment is made of non-woven fabric, is the ventilation compartment a normal shoji regardless of the upper ventilation state or the lower ventilation state? You can get a refreshing appearance like this.

In the fourth characteristic configuration of the present invention, the intake space of the exhaust unit is arranged on the lateral side of the perimeter space when viewed from the indoor space side, and the intake compartment that partitions the intake space and the perimeter space is formed. A non-breathable compartment that can be repositioned in the vertical direction is provided, and the non-breathable compartment is configured to be repositioned downward to switch to the upper intake state and to be repositioned upward to switch to the lower intake state. It is in the point of being done.

According to this configuration, the intake space of the exhaust unit is arranged on the side of the perimeter space when viewed from the indoor space side. Therefore, for example, a glass window or the like is arranged in front of the interior when viewed from the indoor space side. You can appreciate the outdoor scenery from the space side.
Then, the intake compartment that partitions the intake space and the perimeter space is provided with a non-breathable compartment that can be repositioned in the vertical direction, and by changing the position of the non-breathable compartment, the upper intake state and the lower intake are taken. Since it can be switched to the state, it is structurally simple and the switching operation is easy. For example, automation using an electric actuator is also easy.

In the fifth characteristic configuration of the present invention, the intake compartment is provided with a breathable compartment that can be repositioned in the vertical direction, and the breathable compartment is repositioned upward to bring the intake compartment downward. The point is that the position is changed to switch to the lower intake state.

According to this configuration, the intake compartment is provided with a breathable compartment that can be repositioned in the vertical direction in addition to the non-breathable compartment described above, and the upper intake is obtained by repositioning the breathable compartment. Since it is possible to switch between the state and the lower intake state, the intake space of the exhaust part is the non-breathable section and the breathable section when viewed from the indoor space or the perimeter space side in both the upper intake state and the lower intake state. It is covered by the part.
Therefore, when viewed from the indoor space or the perimeter space side, the intake space of the exhaust portion can be covered with the intake compartment, and the intake compartment can be made to have a neat appearance. For example, if the non-breathable compartment is made of Japanese paper and the breathable compartment is made of non-woven fabric, is the intake compartment a normal shoji regardless of the upper or lower intake state? You can get a refreshing appearance like this.

An embodiment of the ventilation structure of the perimeter space according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the ventilation structure of the perimeter space of the present invention is divided into a perimeter space 6 adjacent to the glass window 5 and an indoor space 7 other than the inside of the building by a ventilation compartment 1. As shown in FIGS. 2A and 3A, the ventilation compartment 1 is a non-breathable compartment 2 and a breathable compartment that can be manually repositioned in the vertical direction and can be held in the vertical direction. It is configured to include a part 3. The areas of the non-breathable compartment 2 and the breathable compartment 3 in the front view can be appropriately set. For example, the area of the non-breathable compartment 2 is equal to or smaller than the area of the breathable compartment 3. Can also be set widely.
In this embodiment, an area like the upper space of the Shoin shelf is set in the perimeter space 6, but the setting of the perimeter space 6 can be freely changed in consideration of the floor plan of the building and the like. ..

The non-breathable compartment 2 of the ventilation compartment 1 is composed of a shoji covered with non-breathable Japanese paper, and the breathable compartment 3 is composed of a shoji covered with a breathable non-woven fabric. The body 1 has a shoji-like appearance as a whole. Then, although not shown, the non-breathable compartment 2 and the breathable compartment 3 are slidably fitted into the grooves provided on both the left and right sides, and their positions are changed in the vertical direction as if they were a snow shoji. The breathable compartment 3 made of non-woven fabric, which is freely and can hold the position in the vertical direction, functions as a ventilation portion 4 that enables ventilation from the indoor space 7 to the perimeter space 6.
Therefore, as shown in FIG. 2A, the breathable compartment 3 is located above and the non-breathable compartment 2 is located below, so that the ventilation compartment 1 becomes the indoor space 7. The upper ventilation state has the ventilation portion 4 with the perimeter space 6 above the perimeter space 6. On the contrary, as shown in FIG. 3A, the non-breathable compartment 2 is located above and the breathable compartment 3 is located below, so that the downward ventilation having the ventilation portion 4 below it is performed. It becomes a state and is configured to be freely switchable between an upward ventilation state and a downward ventilation state.

As shown in FIG. 1, the exhaust unit 8 that takes in and exhausts the inside of the perimeter space 6 is a columnar exhaust chamber 9 and an exhaust fan 10 arranged on the lateral side of the perimeter space 6 when viewed from the indoor space 7 side. , And an exhaust duct 11 connecting them. The exhaust chamber 9 can be arranged along the pillar 13 in a state of including the pillar 13 of the building, for example.
The exhaust fan 10 is for ventilating the inside of the bathroom (not shown), the suction side of the exhaust fan 10 is connected to the exhaust chamber 9 via the exhaust duct 11, and the internal space of the exhaust chamber 9 is the exhaust fan. It is set to the intake space 12 which is taken in by 10. That is, the intake space 12 of the exhaust unit 8 is arranged on the lateral side of the perimeter space 6 when viewed from the indoor space 7 side, and the intake space 12 and the perimeter space 6 are partitioned by the intake compartment 14.
In this embodiment, the exhaust fan 10 for the bathroom is also used for the exhaust unit 8, but it is also possible to provide a dedicated exhaust fan or also use an exhaust fan other than the one for the bathroom. ..

The intake compartment 14 has the same configuration as the ventilation compartment 1 described above, and as shown in FIGS. 2 (b) and 3 (b), the position can be manually changed in the vertical direction and the vertical direction. The non-breathable compartment 15 and the breathable compartment 16 that can hold the position in the above are provided. The areas of the non-breathable compartment 15 and the breathable compartment 16 in the front view can be appropriately set. For example, the area of the non-breathable compartment 15 is equal to or smaller than the area of the breathable compartment 16. Can also be set widely.
The non-breathable compartment 15 of the intake compartment 14 is composed of a shoji covered with non-breathable Japanese paper, and the breathable compartment 16 is composed of a shoji covered with a breathable non-woven fabric. The body 14 has a shoji-like appearance, and the non-breathable compartment 15 and the breathable compartment 16 are slidably fitted into a groove (not shown) as in the case of the ventilation compartment 1 above. , Like a snow shoji, the position can be changed in the vertical direction and the position can be held in the vertical direction.
Since the intake compartment 14 is composed of obstacles, a lighting fixture is arranged inside the intake space 12, and the light of the lighting fixture is transmitted through the intake compartment 14, so that the perimeter is not shown. It can be used as indirect lighting for the space 6 and further, the indoor space 7. In that case, the lighting fixture is arranged inside the intake space 12, but the non-breathable compartment 15 and the breathable compartment 16 of the intake compartment 14 can be repositioned and held in the vertical direction, respectively. Therefore, the maintenance of the lighting equipment becomes easy.

Then, the breathable compartment 16 made of non-woven fabric functions as an intake unit 17 that takes in air from the perimeter space 6 in the exhaust unit 8 that takes in and exhausts the inside of the perimeter space 6.
Therefore, as shown in FIG. 3B, by making the breathable compartment 16 located above and the non-breathable compartment 15 located below, the exhaust section 8 takes in air from the perimeter space 6. It is in an upward intake state with the portion 17 above it. On the contrary, as shown in FIG. 2B, the non-breathable compartment 15 is located above and the breathable compartment 16 is located below, so that the intake portion 17 is located below the lower intake. It becomes a state and is configured to be freely switchable between an upper intake state and a lower intake state.

In the ventilation structure of the perimeter space having such a configuration, when the outside air temperature is extremely lower than the room temperature, for example, in winter, as shown in FIGS. 2A and 2B, It is used by switching to the first mode in which the ventilation compartment 1 is in the upward ventilation state and the exhaust unit 8 is in the downward intake state. On the other hand, when the outside air temperature is extremely higher than the indoor temperature, such as in summer, the ventilation compartment 1 is in a downward ventilation state and the exhaust unit is as shown in FIGS. 3A and 3B. It is used by switching to the second mode in which 8 is the upper intake state.
Then, in the first mode, the cold air in the perimeter space 6 affected by the outdoor conditions is taken in from below, and the warm air in the indoor space 7 flows into the perimeter space 6 from above with an ideal air flow. Be ventilated. On the other hand, even in the second mode, the warm air in the perimeter space 6 affected by the outdoor conditions is taken in from above, and the cold air in the indoor space 7 flows into the perimeter space 6 from below with an ideal air flow. Be ventilated.
Further, from the viewpoint of air conditioning heat load, when there is a relatively large temperature difference between the outside air temperature and the room temperature, the above-mentioned ideal air flow is used to ventilate the perimeter space 6. , The temperature in the perimeter space 6 affected by the outside air temperature approaches the temperature in the indoor space 7. Then, the once-through heat load of the indoor space 7 via the perimeter space 6 is reduced, which can be useful for energy saving.
