Description

TECHNICAL FIELD The present invention relates to a ventilation structure for a perimeter space, which includes a ventilation partition for partitioning an indoor space and a perimeter space, and an exhaust section for sucking air into the perimeter space and discharging the air from the perimeter space.

Here, the term "perimeter space" means an indoor space in a building, such as a window side or a wall side, which is susceptible to outdoor conditions such as sunlight and outside temperature.
Therefore, the air in the perimeter space, which is affected by outdoor conditions such as the outside temperature, flows into the indoor space while warm air rises in summer and cool air falls in winter. 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 draws air into the perimeter space and exhausts it are provided. By winding it up a little, it is possible to freely switch to a lower ventilation state in which the lower side communicates, and furthermore, the exhaust fan is configured to be freely switchable between an upper air intake state in which air is sucked from the upper cross-air passage and a lower air intake state in which air is drawn from the lower cross-air passage. A perimeter space ventilation structure has been proposed (see, for example, Patent Document 1).

JP-A-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, cold air in the perimeter space affected by the outdoor conditions is taken in from below, but since the roll screen is fully closed, warm air in the indoor space is forced to the sides and top of the roll screen. Air flows 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, part of the cool air in the perimeter space may stay above the perimeter space and flow into the interior space from both sides of the roll screen.

The present invention focuses on such conventional problems, and its purpose is to maintain the comfort of the indoor space by always reliably ventilating the entire perimeter space with an ideal air flow. It is to provide a perimeter space ventilation structure that is possible.

A first characteristic configuration of the present invention is a ventilation structure for a perimeter space comprising a ventilation partition that partitions an indoor space and a perimeter space, and an exhaust part for sucking in and discharging the inside of the perimeter space, wherein the ventilation The partition body is configured to be switchable between an upper ventilation state in which a ventilation section for the indoor space and the perimeter space is provided above it and a lower ventilation state in which the ventilation section is provided below the ventilation section, and the exhaust section is an intake section from the perimeter space. a first mode in which the partition for ventilation is in the upper ventilation state and the exhaust section is in the lower intake state; It is characterized in that it is configured to be switchable between a second mode in which the air compartment is in the downward ventilation state and the exhaust section is in the upward intake state.

According to this configuration, for example, when the outside temperature is extremely lower than the indoor temperature, such as in winter, the mode is switched to the first mode, and the outside temperature is extremely higher than the indoor temperature, such as in summer. can be switched to the second mode.
In the first mode, the ventilation partition is in the upward ventilation state and the exhaust section is in the downward intake state, and the cold air in the perimeter space affected by the outdoor conditions is sucked from below, and the warm air in the indoor space is sucked. Since cold air flows into the perimeter space from above, the entire perimeter space is ventilated with an ideal air flow in which cool air descends.
In the second mode, the ventilation partition is in the downward ventilation state and the exhaust section is in the upward intake state, and 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 warm air flows into the perimeter space from below, the entire perimeter space is ventilated with an ideal air flow in which warm air rises.
As a result, in both the first mode and the second mode, the inside of the perimeter space is always reliably ventilated with an ideal air flow, and the comfort of the indoor space is maintained.

In a second characteristic configuration of the present invention, the ventilation partition includes a non-air-permeable partition part whose position can be changed in the vertical direction, and the position of the non-air-permeable partition part is changed downward to achieve the upward ventilation state, The point is that it is configured to change its position upward and switch to the downward ventilation state.

According to this configuration, the ventilation partition has a non-air-permeable partition part whose position can be changed in the vertical direction, and the position of the non-air-permeable partition part can be changed to switch between an upper ventilation state and a lower ventilation state. Therefore, the structure is simple and the switching operation is easy. For example, automation using an electric actuator is easy.

In a third characteristic configuration of the present invention, the ventilation partition has a breathable partition portion whose position can be changed in the vertical direction, and the position of the breathable partition portion is changed upward to achieve the upward ventilation state and downward. The point is that it is configured to switch to the downward ventilation state by changing the position.

According to this configuration, in addition to the above-described non-breathable partition, the ventilation partition includes a breathable partition that can be changed in position in the vertical direction. The perimeter space is covered with the non-ventilated compartment and the ventilated compartment when viewed from the interior space side in both the upward ventilated state and the downward ventilated state.
Therefore, when viewed from the interior space side, the perimeter space can be covered with the ventilation partition, and the ventilation partition can have a neat appearance. For example, if the non-breathable partition is made of Japanese paper and the breathable partition is made of non-woven fabric, the ventilation partition is just like a normal shoji regardless of whether it is in an upward or downward ventilation state. It is possible to obtain a clean appearance such as

In a fourth characteristic configuration of the present invention, an intake space of the exhaust section is arranged laterally of the perimeter space when viewed from the interior space side, and an intake partition body that separates the intake space and the perimeter space is provided. a non-air-permeable compartment whose position is changeable in the vertical direction, wherein the position of the non-air-permeable compartment is changed downward to switch to the upper air intake state and upward to switch to the lower air intake state. It is in the point that it is done.

According to this configuration, the intake space of the exhaust section is arranged laterally of the perimeter space when viewed from the indoor space side. You can appreciate the scenery outside from the space side.
The air intake partitioning body for partitioning the air intake space and the perimeter space has a non-breathable partition portion whose position can be changed in the vertical direction. Since it is possible to switch between the two states, the structure is simple and the switching operation is easy. For example, automation using an electric actuator is facilitated.

According to a fifth characteristic configuration of the present invention, the air intake partition has an air-permeable partition part whose position can be changed in the vertical direction, and the position of the air-permeable partition part is changed upward to achieve the upper air intake state and downward. The point is that it is configured to change the position and switch to the lower intake state.

According to this configuration, the air intake partition has a breathable partition whose position can be changed in the vertical direction in addition to the above-described non-breathable partition. state and the lower air intake state, the air intake space of the exhaust part is divided into non-breathable compartments and air-permeable compartments when viewed from the interior space or perimeter space side in both the upper air intake state and the lower air intake state. obscured by the department.
Therefore, when viewed from the interior space or the perimeter space side, the air intake space of the exhaust section can be covered with the air intake partition, and the air intake partition can have a neat appearance. For example, if the non-breathable partition is made of Japanese paper and the breathable partition is made of non-woven fabric, the air intake partition is just like a normal shoji regardless of whether it is in the upper air intake state or the lower air intake state. It is possible to obtain a clean appearance such as

A part 3 is provided. The area of each of the impermeable partition 2 and the breathable partition 3 in a front view can be appropriately set. can be set wider.
In this embodiment, the perimeter space 6 is defined as an upper space of a study shelf, but the setting of the perimeter space 6 can be freely changed in consideration of the layout of the building. .

The non-breathable partition 2 of the ventilation partition 1 is made of a shoji covered with non-breathable Japanese paper, and the breathable partition 3 is made of a shoji covered with breathable non-woven fabric. The body 1 presents an appearance like a shoji as a whole. The non-air-permeable partition 2 and the air-permeable partition 3, though not shown, are slidably fitted into grooves provided on both the left and right sides, and their positions can be changed in the vertical direction as if they were snow-viewing shoji screens. The air-permeable compartment 3 made of non-woven fabric, which is flexible and capable of holding its position in the vertical direction, functions as a ventilation part 4 that allows ventilation from the indoor space 7 to the perimeter space 6 .
Therefore, as shown in FIG. 2( a ), by placing the breathable partition 3 above and the non-breathable partition 2 below, the ventilation partition 1 can be separated from the indoor space 7 . It is in an upper ventilation state having the ventilation part 4 with the perimeter space 6 above it. Conversely, as shown in FIG. 3( a ), the non-breathable partition 2 is positioned above and the breathable partition 3 is positioned below, so that the lower ventilation part having the ventilation part 4 below it is provided. It is configured to be switchable between an upper ventilation state and a lower ventilation state.

As shown in FIG. 1, the exhaust unit 8 for sucking and discharging the inside of the perimeter space 6 includes a columnar exhaust chamber 9 and an exhaust fan 10 arranged laterally of the perimeter space 6 when viewed from the room space 7 side. , and an exhaust duct 11 connecting them. The exhaust chamber 9 can for example be arranged along the pillar 13 enclosing the pillar 13 of the building.
The exhaust fan 10 is for ventilating the inside of the bathroom (not shown). 10 is set in the intake space 12 to be taken in. That is, the intake space 12 of the exhaust section 8 is arranged laterally of the perimeter space 6 when viewed from the interior space 7 side, and the intake space 12 and the perimeter space 6 are partitioned by the intake partition 14 .
In this embodiment, the exhaust fan 10 for the bathroom is also used as the exhaust unit 8, but it is also possible to provide a dedicated exhaust fan or to use the exhaust fan for purposes other than the bathroom. .

The intake partition 14 has the same structure as the ventilation partition 1 described above, and as shown in FIGS. It is configured with a non-breathable partition 15 and an air-permeable partition 16 that can be held in position. The area of each of the impermeable partition 15 and the breathable partition 16 in a front view can be appropriately set. can be set wider.
The non-breathable compartment 15 of the air intake partition 14 is made of a shoji covered with non-breathable Japanese paper, and the air-permeable compartment 16 is made of a shoji covered with air-permeable nonwoven fabric. The body 14 has an appearance like a shoji screen, and the non-air-permeable partition 15 and the air-permeable partition 16 are slidably fitted in grooves (not shown) as in the case of the previous ventilation partition 1. , as if it were a snow-viewing shoji screen, each of which is vertically changeable and vertically retainable.
Since the air intake partition 14 is made of a shoji screen, although not shown, a lighting fixture is arranged inside the air intake space 12, and the light from the lighting fixture is transmitted through the air intake partition 14, so that the perimeter It can be used as indirect lighting for the space 6 and further for the indoor space 7 . In this case, the lighting equipment is arranged inside the air intake space 12, but the non-air-permeable partition 15 and the air-permeable partition 16 of the air intake partition 14 can be vertically changed and held. Therefore, the maintenance of the lighting equipment becomes easy.

The air-permeable compartment 16 made of non-woven fabric functions as an intake section 17 for sucking air from the perimeter space 6 in the exhaust section 8 for sucking air into and discharging the inside of the perimeter space 6 .
Therefore, as shown in FIG. 3B, by locating the air-permeable partition 16 above and the non-air-permeable partition 15 below, the exhaust part 8 can absorb air from the perimeter space 6. It will be in an upward intake state with the portion 17 above it. Conversely, as shown in FIG. 2(b), the air-impermeable compartment 15 is located above and the air-permeable compartment 16 is located below, so that the air intake part 17 is located below it. state, and is configured to be switchable between an upper intake state and a lower intake state.

In the perimeter space ventilation structure having such a configuration, for example, when the outside temperature is extremely low compared to the inside temperature, such as in winter, as shown in FIGS. 2(a) and 2(b), It is used by switching to the first mode in which the ventilation partition 1 is in the upward ventilation state and the exhaust part 8 is in the downward intake state. On the other hand, when the outside air temperature is extremely higher than the room temperature, such as in summer, as shown in FIGS. 8 is used by switching to the second mode, which is the upward intake state.
In the first mode, cold air in the perimeter space 6 affected by the outdoor conditions is taken in from below, and warm air in the indoor space 7 flows into the perimeter space 6 from above in 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. be ventilated.
Further, from the viewpoint of the air conditioning heat load, when there is a relatively large temperature difference between the outside air temperature and the room temperature, the perimeter space 6 can be ventilated with the ideal air flow described above. , the temperature in the perimeter space 6 affected by the outside air temperature approaches the temperature in the indoor space 7 . As a result, the flow heat load of the indoor space 7 via the perimeter space 6 is reduced, which contributes to energy saving.
