Description

[Detailed description of the invention] Industrial application field The present invention relates to a wind direction deflection device that is installed inside the discharge port of an air conditioner (hereinafter referred to as an air conditioner) and guides discharged air in any vertical direction. .

Conventional configurations and their problems Traditionally, air conditioners have been required to provide comfortable air conditioning for living spaces. Elemental technology is being researched.

A conventional wind direction deflection device for an air conditioner under this situation will be described below with reference to the drawings.

Conventionally, for example, a ceiling-hung air conditioner is equipped with a wind direction deflection device to blow cold air horizontally during cooling, and blow warm air downward during heating. It is of the configuration shown.

That is, in this figure, 1 indicates the air conditioner main body,
A discharge port 2 is formed on the front surface. In front of the discharge port 2, there is provided a discharge grille 3 mainly composed of a horizontal machine and a vertical machine, and inside the discharge port 2, a fluid guide plate 4 (hereinafter referred to as a fluid plate) having a curved surface is provided below. A vertical wind direction deflection device is formed by providing a rotatable horizontal control plate 5 (hereinafter referred to as a control plate) above the fluid plate 4 and a right-angled bias section 6 above this.

The operation of the vertical wind direction deflection device configured as described above will be explained below.

First, in the case of downward blowout, as shown in FIG. 9, when the control plate 5 is rotated so that the downstream side faces downward, the jet A below the control plate 5 will cause a Coanda effect on the wall surface of the fluid plate 4. is attached and deflected downward. Further, the jet stream B above the control plate 5 is pushed downward by the back pressure B' from the bias section 6, is attracted by the jet stream A, joins as a jet stream C, and is deflected downward and blown out. Next, in the case of horizontal blowout, as shown in Fig. 10, by rotating the control plate 5 so that the downstream side faces slightly upward, the jet flow A below the control plate 5 is separated from the fluid plate 4, and the At the same time, the jet B above the control plate 5 is pushed downward by the back pressure B' from the bias section 6, but is pushed back horizontally by the control plate 5 and merges with the jet A. , which is blown out horizontally as a jet C.

With the above configuration, there is a problem that air blowing resistance occurs in the bias section 6 during horizontal blowing, and as shown in FIG. Because the specific gravity of the warm airflow is light, the wind blown downwards is directed toward the ceiling, which has the disadvantage that the back of the room is not heated, meaning the temperature distribution in the room is not uniform. .

Purpose of the invention Therefore, in view of the above-mentioned drawbacks, the purpose of the present invention is to obtain a wind direction deflection device that can divide discharged air into two directions in order to enable uniform temperature distribution in the space regardless of the form of the space to be air-conditioned. shall be.

Structure of the invention In order to achieve this object, the wind direction deflection device of the invention includes a horizontal control plate that is rotatably supported within the discharge port, a shielding plate that rotates independently of the horizontal control plate, and a shielding plate that rotates independently of the horizontal control plate. and a fluid guide plate with a curved surface that works together with the shielding plate to generate the Coanda effect. You can switch between dividing the flow and
Regardless of the form of the space to be air-conditioned, uniform temperature distribution is always possible.

DESCRIPTION OF EMBODIMENTS An example in which an embodiment of the present invention is applied to a ceiling-suspended air conditioner will be described below with reference to the accompanying drawings. Components having the same configuration as the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 1, 1 is an air conditioner main body, and the inside of this main body 1 has a fan casing 7 containing a Shirotsko fan (not shown), a motor 8 for driving the fan, and a suction port 9 formed on the bottom surface. The air blowing chamber 10 is partitioned by a partition plate 11, and constitutes a heat exchanger 14 attached to side plates 12 and 13, and a discharge port 2 having a wind direction deflection device to be described later.

The discharge port 2 is connected to the side plates 12 and 13 and the top plate 1.
5. It is divided by a bottom plate 16, and a heat insulating material 17 is pasted along the inner surface of the top plate 15, and a shielding plate 18 that can be rotated from a right angle to a horizontal position is attached to the lower tip part by side plates 12 and 13. It is centrally supported. Further, a drain pan 19 made of a heat insulating material is mounted on the bottom plate 16, and a fluid plate 4 is provided on the surface of this drain pan 19.

A jet guide curved surface 20 that is inclined toward the front side of the discharge port 2 is integrally formed at a position facing the shielding plate 18 in front of the fluid plate 4. A control plate 5 with a shaft 21 rotatably supported between the side plates 12 and 13 is provided between the jet guide curved surface 20 and the shield plate 18, and a horizontal machine is provided at the tip of the discharge port 2. 22,
A discharge grille 3 consisting of a reinforcing vertical machine 23 is installed. A guide wall 24 having a curved surface continuous to the guide curved surface 20 is provided at the lowermost end of the discharge grille 3. These control board 5, shielding board 18,
The arrangement of the jet guide curved surface 20 of the fluid plate 4 and the guide wall 24 of the discharge grille 3 constitutes a vertical wind direction deflection device.

In this configuration, air sucked into the blowing chamber 10 from the suction port 9 is heat-exchanged by adding a heat exchanger 14, and then sent to the discharge port 2. The airflow sent into the discharge port 2 flows into the vertical wind direction deflection device.

Here, in the case of horizontal air blowing during cooling (FIG. 3), by rotating the shielding plate 18 so that it faces horizontally and rotating the downstream end of the control plate 5 so that it faces horizontally, the control board Jet stream B above 5
On the other hand, the shielding plate 18 does not become an obstacle, and the air is blown out smoothly in the horizontal direction. Further, the jet A below the control plate 5 is separated from the jet guide curved surface 20 of the fluid plate 4 and is blown out in the horizontal direction, and merges with the jet B to be blown out in the horizontal direction as the jet C.

Next, in the case of downward blowing during heating, if the space to be air-conditioned is not particularly long in the blowing direction, as shown in FIGS. 4 and 5, the shielding plate 1
8 to face vertically, and the bias portion 6 is formed by the shielding plate 18, top plate 15, and heat insulating material 17, and by rotating the downstream end of the control plate 5 to face downward. The jet A below the control plate 5 adheres to the jet guide curved surface 20 of the fluid plate 4 due to the Coanda effect and is deflected downward. Further, the jet B above the control plate 5 is pushed downward by the back pressure B' by the bias section 6 formed by the shielding plate 18, and is attracted by the jet A deflected downward and joins as the jet C. Then, it is deflected downward and blown out. At this time, as shown in Figure 5,
Since the space to be air-conditioned is not particularly long in the blowing direction, the jet stream C reaches the end of the space to be air-conditioned, making it possible to heat the entire space.

Next, during heating, if the space to be air-conditioned is particularly long in the direction of the air outlet, as shown in FIGS. 6 and 7, the shield plate 18 is rotated to face horizontally, and the control plate 5 is rotated. By rotating so that the downstream end faces downward, the jet A below the control plate 5 adheres to the jet guide curved surface 20 of the fluid plate 4 due to the Coanda effect and is deflected downward. Further, the jet stream B above the control plate 5 is blown out horizontally because no back pressure is generated by the bias section 6 as in the case of FIG. 4. In other words, the jets blown out are in two directions: a downward jet C and a horizontal jet D. At this time, as shown in FIG. 7, since the space to be air-conditioned is particularly long in the direction of the air outlet, the jet flow D flows along the ceiling surface of the room and descends downward at the back of the room, warming the inner part. It is also blown downward by the jet stream C, warming the center of the room.

As described above, according to this embodiment, the combination of the shielding plate 18 that rotates independently and the control plate 5 that rotates allows for more efficient horizontal blowout, and also allows for the configuration of the space to be air-conditioned during heating. Regardless of the temperature, it is possible to always maintain a uniform temperature distribution.

Effects of the Invention As described above, the present invention includes: a horizontal control plate that is rotatably supported within the discharge port; a shielding plate that is provided above the horizontal plate and rotates independently of the horizontal control plate; It consists of a fluid guide plate having a jet flow guide curved surface that works together with the horizontal control plate and the shielding plate to generate a Coanda effect.In the case of horizontal blowout during cooling, by rotating the shielding plate horizontally, In addition to being able to efficiently blow air, it is possible to switch between a bottom blowout jet and a case where part of the bottom blowout jet is divided horizontally depending on the shape of the space to be air-conditioned during heating, regardless of the space shape. It is possible to always maintain a uniform temperature distribution,
Its practical effects are significant.
