When the air outlet 8 on the rear partition 3 faces the left-side partition 5, the conditioned air stream blown from the air outlet 8 on the rear partition 3 strikes on the flat part 6B of the left side partition 5 and changes the flow direction as it spreads into a broader area, however, much of the stream flows along the left-side partition.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an air conditioner for personal use.

[Conventional technology]

BACKGROUND ART Nowadays, many air conditioners are becoming widespread, and when many people work in a room such as an office room, the room is divided into many spatial areas using partitions or the like. In such cases, in order to create a working environment in which the air temperature and other factors match individual preferences, there are an increasing number of personal air conditioners that separately supply conditioned air to workers located in different spatial areas within the room.

FIG. 13 shows an example of a conventional personal air conditioner.

In the figure, 101 is a front partition installed in an office room (not shown), and a rear partition 102 is installed opposite to this front partition 101. Further, the front partition 101 and the rear partition lO2 are connected by a right partition 103, and a left partition 104 is continuous with the front partition 101.

A personal space area 106 is surrounded by a wall surface 105 consisting of a front partition 101, a rear partition 102, a right partition 103, and a left partition 104.

The front partition Lot has an outlet 107 that blows out conditioned air.
is fixed.

Therefore, the air outlet 107 of the front partition 101 is closed to the operator B.
The conditioned air from this outlet 107 is blown directly to the worker B.

(Problem to be Solved by the Invention) However, in the conventional personal air conditioner, the opening area of the air outlet 107 is small, and therefore, the airflow from the air outlet i07 covers part of the body of the worker B. Furthermore, since the distance from the air outlet 107 to worker B is short and the blowing airflow is fast, the blowing airflow has a strong influence on worker B, and worker B receives wind close to natural airflow. I can't.

Further, since the worker B is always locally exposed to the blown air current on a part of his body, the thermal influence of the blown air flow is also large, which is undesirable for his health.

The present invention has been made to solve the above-mentioned problems, and its purpose is to diffuse the airflow blown out from the air outlet and blow it at an appropriate speed to the worker, so that the air flow is close to the natural wind for the worker. The purpose of the present invention is to provide an air conditioner that can blow wind.

[For production]

The following effects occur in the present invention.

In the invention according to claim 1, the airflow of conditioned air blown out from the outlet on the wall changes direction when it hits a flat plate-shaped part of the wall that is located at a predetermined angle away from the wall where the outlet is provided. While spreading over a wide area, most of it travels along the wall surface, and some of it travels toward the worker.

In the invention according to claim 2, the airflow of the conditioned air blown out from the air outlet on the wall surface hits an airflow direction changing concave surface provided on the wall surface located at a predetermined angle away from the wall surface where the air outlet is provided. Then, the airflow changes direction and advances while being guided in the tangential direction by the airflow direction changing concave surface and spread over a wide area.

Most of this redirected airflow travels in the direction of the worker.

In the invention according to claim 3, the air flow of conditioned air blown out from the outlet of the blow-off device installed on the ceiling is as follows:
When the air hits a concave surface for changing the airflow direction provided on the wall surface, it is guided in the tangential direction by the concave surface for changing the airflow direction, and changes direction and moves while being diffused over a wide area. Most of this redirected blow-off airflow goes in the direction of the worker.

In the invention according to claim 4, when the airflow of the conditioned air blown out from the air outlet in the ceiling hits the airflow direction changing concave surface provided on the wall surface, it is guided in the tangential direction by the airflow direction changing concave surface and widens. Change direction and move forward while spreading out over the area. Most of this redirected blow-off airflow goes in the direction of the worker.

〔Example) Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an air conditioner according to a first embodiment of the present invention.

In Fig. 1, reference numeral 1 denotes a front partition installed in an office room (not shown), and this front partition 1 has an exhaust port 2.
is provided. The exhaust port 2 efficiently removes heat generated from the OA equipment E.

A rear partition 3 is installed opposite the front partition 1. Further, the front partition l and the rear partition 3 are connected by a right partition 4, and this right partition 4 has a flat plate-shaped part 6.
A is formed. A left side partition 5 continues at right angles to the front partition 1, and a flat plate-shaped portion 6B is formed in this left side partition 5.

A personal space area 7 is defined by the front partition 1, the rear partition 3, the right partition 4, and the left partition 5.

The rear partition 3 is provided with an outlet 8 for blowing out conditioned air, and as shown in FIG. It has a cylindrical body 8A inside and has a structure that allows it to be manually oriented in all 360 degrees.

Therefore, the outlet 8 of the rear partition 3 faces toward the left-hand partition 5, and the airflow of conditioned air blown out from the outlet 8 of the rear partition 3 is directed to the flat plate-shaped portion 6B of the left-hand partition 5.
When it hits, most of it travels along the left partition 5 while changing direction and spreading over a wide area, and a part of it travels in the direction of worker B and hits worker B's body.

According to the above configuration, when the airflow from the air outlet 8 provided in the rear partition 3 hits the flat plate-shaped portion 6B of the left partition 5, it changes direction and spreads over a wide area, and a part of the air flows towards the worker. Although it goes in the direction of B, most of it is on the left side partition 5.
Proceed along. Moreover, the distance from the air outlet 8 to the worker B becomes longer, and the air flow slows down. Therefore, the influence of the blown airflow on the worker B can be weakened, and wind close to natural wind can be sent to the worker B.

Further, since most of the airflow whose direction has been changed by the flat plate-shaped portion 6B advances along the left partition 5, the heat of the airflow can provide a radiant effect to the worker B.

Furthermore, since the blowing airflow becomes weaker, the thermal influence of the blowing airflow on the worker B is also small, and the influence on the health of the worker B can be reduced.

Since a wall of air is formed around the worker B by the blown air current, this wall can also block heat from the surroundings.

In short, while the airflow that does not blow out from the air outlet 8 is diffused by the flat plate-shaped portion 6B of the left partition 5, only a part of it is directed toward the worker, and the airflow of conditioned air is sent in the direction of the worker B at a slow speed. Wind similar to natural wind can be sent to worker B.

In the first embodiment, the front partition 1, the rear partition 3, the right partition 4, and the left partition 5 form a substantially C-shaped continuous wall surface. The shape is not limited to a circular cross-sectional shape, a triangular closed cross-sectional shape, or an L-shape.

Further, in the first embodiment, a partition is used as a wall surface, but the present invention is not limited to a partition, and can also be applied to a wall surface of a fixed structure.

Further, in the first embodiment, the air outlet 8 is provided in the rear partition 3, and correspondingly, the airflow direction changing concave plate 1)

can also be provided on the right side partition 4 or the left side partition 5.

In the first embodiment, the air outlet 8 formed in the spherical body 10 has a cylindrical body 8A, but instead of this cylindrical body 8A, it is made of a cylindrical body and has two air outlets at the tip. It is also possible to provide a V-shaped inverted blow-off section.

As shown in FIG. 3, the right partition 4 and the left partition 5 each have a curved airflow direction changing concave plate 1). 1) is provided. As shown in FIG. 4, the tangent 12 at the end 1)A of the airflow direction changing concave plate 1) points in the direction of the operator B.

Therefore, the air outlet 8 of the rear partition 3 faces the airflow direction changing concave plate 1), and when the airflow of conditioned air blown from the airflow outlet 8 hits the airflow direction changing concave plate 1), it is shown in FIG. As shown, the airflow is guided in the direction of the tangent line 12 by the airflow direction changing concave plate 1), and changes direction and advances while being diffused over a wide area. Most of this direction-changed blow-off airflow advances in the direction of worker B. Here, according to the position or preference of the worker B, for example, as shown in FIG. 5, the bending of the airflow direction changing concave plate 1) can be made stronger.

According to the above configuration, when the airflow from the outlet 8 of the rear partition 3 hits the airflow direction changing concave plate 1), it is guided in the direction of the tangent line 12 by the airflow direction changing concave plate 1), and the direction is changed. The airflow can be changed over a wide area, and most of the airflow can be directed toward worker B. At the same time, the distance from the air outlet 8 to worker B becomes longer, and the blowing airflow becomes slower, so the influence of the blowing airflow on worker B can be weakened, and worker can be sent.

Further, since a part of the airflow whose direction has been changed by the airflow direction changing concave plate 1) advances along the left partition 5, the heat of the airflow can provide a radiant effect to the worker B.

Furthermore, since the blowing airflow becomes weaker, the thermal influence of the blowing airflow on the worker B is also small, and the influence on the health of the worker B can be reduced.

In short, while the airflow blowing out from the airflow outlet 8 is diffused by the airflow direction changing concave plate 1), most of it is directed towards the worker B, and the airflow of conditioned air is sent in the direction of the worker B at a slow speed. It is possible to send wind close to natural wind to the area.

In the second embodiment, a continuous wall surface is constructed by the front partition l, the rear partition 3, the right partition 4, and the left partition 5, but the overall shape of the wall surface is not limited to the above example. , a circular closed cross-sectional shape, a triangular closed cross-sectional shape, or an L-shape.

Further, in the second embodiment, a partition is used as a wall surface, but the present invention is not limited to a partition, and can also be applied to a wall surface of a fixed structure.

Furthermore, in the second embodiment, the air outlet 8 is provided in the rear partition 3, and correspondingly the airflow direction changing concave plate 1)
are provided in the right partition 4 and the left partition 5, however, as shown in FIG. 6, the air outlet 8 can also be provided in the front partition l. Alternatively, the air outlet 8 may be provided in the front partition 1 and the rear partition 3. Or air outlet 8
can also be provided on the right partition 4 or the left partition 5, in which case the airflow direction changing concave plate 1) may be provided on the front partition 1 or the rear partition 3.

In the second embodiment, as shown in FIG.
The air outlet 8 formed in the spherical body 10 has a cylindrical body 8A, but instead of this cylindrical body 8A, a square-shaped downward type air outlet part made of a cylindrical body and having two air outlets at the tip is used. It is also possible to provide one.

Furthermore, in the second embodiment, "right side partition 4
And the left partition 5 has a concave plate 1) for changing the airflow direction.
．． 1), such an airflow direction changing concave plate 1). Even without 1), right side partition 4 and left side partition 5
It is also possible to form an airflow direction changing concave surface having the same function as the airflow direction changing concave plate 1), respectively.

Further, in the second embodiment, the airflow direction changing concave plate 1) has a curved shape, but as shown in FIG. 7, it can also have a dogleg shape.

Therefore, the air outlet 26 faces the airflow direction changing concave plate 29, and when the airflow of the conditioned air blown out from the airflow outlet 26 hits the airflow direction changing concave plate 29, the airflow direction changing concave plate 29 directs the tangential direction of the airflow. Most of this direction-changed blow-off airflow moves in the direction of the worker B, while being guided by the worker B and changing direction while being diffused over a wide area.

According to the above configuration, the airflow from the airflow outlet 26 in the anemostat 22 is directed to the airflow direction changing concave plate 29.
When the airflow hits the airflow direction, it is guided in the tangential direction by the airflow direction changing concave plate 29, and the airflow changes direction and spreads over a wide area, so that most of the airflow can be directed towards the worker B. At the same time, the distance from the air outlet 26 to worker B becomes longer, and the blowing airflow becomes slower, so the influence of the blowing airflow on worker B can be weakened, and wind close to natural wind is sent to worker B. be able to.

Further, since a part of the airflow whose direction has been changed by the airflow direction changing concave plate 29 advances along the partition 28, the heat of the airflow can provide a radiant effect to the worker B.

Furthermore, since the blowing airflow becomes weaker, the thermal influence of the blowing airflow on the worker B is also small, and the influence on the health of the worker B can be reduced.

In short, the airflow blown out from the air outlet 26 is diffused by the airflow direction changing concave plate 29, and most of it is directed toward the worker B, and the airflow of conditioned air is sent in the direction of the worker B at a slow speed. It can send wind close to natural wind.

In the third embodiment, the partition 28 is provided with the airflow direction changing concave plate 29, but even if the airflow direction changing concave plate 29 is not provided, the partition 28 may have a similar airflow direction changing concave plate 29.

〔Effect of the invention〕

In the invention according to claim 1, when the airflow from the outlet on the wall hits a flat plate-shaped part of the wall located at a predetermined angle from the wall where the outlet is provided, it changes direction and spreads over a wide area. Although some of it travels in the direction of the worker, most of it travels along the wall surface located at a predetermined angle away from the wall surface where the air outlet is provided. Moreover, the distance from the air outlet to the worker becomes longer, and the air flow slows down.

Therefore, the influence of the blown air current on the worker can be weakened, and wind close to natural wind can be sent to the worker.

Further, since the blowing air current becomes weaker, the thermal influence of the blowing air current on the worker is also small, and the influence on the health of the worker can be reduced.

In short, the airflow blowing out from the air outlet is diffused by the flat plate-shaped part of the wall surface, and only a part of it is directed toward the worker, and the airflow of conditioned air is sent in the direction of the worker at a slow speed.
This has the effect of sending wind close to natural wind to workers.

In the invention according to claim 2, when the airflow from the outlet on the wall hits the airflow direction changing concave surface provided on the wall located at a predetermined angle from the wall on which the outlet is provided, the airflow direction changes. The modified concave surface allows it to be guided tangentially and redirected to spread over a large area and direct most of its airflow towards the operator. At the same time, since the distance from the outlet to the worker becomes longer and the blowing airflow becomes slower, the effect of the blowing airflow on the worker can be weakened, and wind close to natural wind can be sent to the worker.

Further, since the blowing air current becomes weaker, the thermal influence of the blowing air current on the worker is also small, and the influence on the health of the worker can be reduced.

In short, the airflow blowing out from the outlet is diffused by the airflow direction changing concave surface, and most of it is directed towards the worker, and the airflow of conditioned air is sent in the direction of the worker at a slow speed, which is similar to the natural wind for the worker.
