Description

[Detailed description of the invention] (Industrial application field) This invention relates to an air blowing direction adjustment device for an air conditioning air outlet that is attached to a ceiling in order to send cooling and heating air to a room, etc. in an air conditioner. This invention relates to an improvement of the air outlet for air conditioning and heating disclosed in Japanese Utility Model Publication No. 17424/1983, which was already proposed by the present applicant.

(Prior art) In other words, the cooling and heating air outlet proposed in Japanese Utility Model Publication No. 42-17424 has a cylindrical body with a smaller diameter inside the cylindrical outlet body, and the outer circumferential surface of this cylindrical body and the air outlet. It is supported via a support rod so that an outer air outlet is provided between the inner circumferential surface of the outlet body, and inside the cylinder body, a disk body having a disk section at the bottom is connected to the lower end of the cylinder body. The support rod is vertically movably supported on the support tube of the support rod via a threaded rod so that an inner air outlet is provided between the outer peripheral end of the panel part, and the air blower is provided at the upper end of the screw rod above the cylinder. An annular plate having an air circulation hole of approximately the same diameter as the cylindrical body in the center of the circular plate having approximately the same diameter as the inner diameter of the outlet body was fixed so as to move up and down at the same time as the disk body. During cooling, the disk and the annular plate are rotated and lowered to close the upper end of the outer air outlet between the outer circumferential surface of the cylinder and the inner circumferential surface of the outlet body, and at the same time The inner air outlet between the lower end and the outer circumference of the panel is opened, and during heating, the disk and annular plate are rotated and raised in the opposite direction to the case of cooling, and the outer circumferential surface of the cylinder and the annular plate are raised. The upper end of the outer air outlet between the inner circumferential surface of the outlet body is opened, and at the same time, the inner air outlet between the lower end of the cylinder and the outer circumferential edge of the board is closed.

In addition, in part, an air diffusion plate is disposed inside the casing consisting of a cylindrical part and a diverging part with a desired gap in the divergent part, and an air diffusion plate is arranged in the cylindrical part so as to be vertically movable. A hollow cylindrical damper is provided, and a control rod is arranged upward from below the air diffusion plate and coupled to the damper, and the control rod is actuated to move the damper up and down, and the wide-spread part of the casing and the control rod are connected to the damper. An air supply/exhaust port device (Japanese Unexamined Patent Publication No. 164247/1983) has been proposed which controls the flow rate of air passing through a gap with an air diffusion plate.

(Problem to be solved by the invention) However, in the former case, during cooling and heating, the panel body and the annular plate are lowered and raised while rotating, so it is extremely difficult to adjust the air blowing direction. During cooling, cold air passes through the inside of the cylindrical body from the air circulation hole in the center of the annular plate and hits the panel at the bottom of the panel, and the inner air between the lower end of the cylindrical body and the outer peripheral edge of the panel Because the cold air is blown out horizontally to the sides only from the air outlet, the cold air is spread horizontally to the sides too much, and the cold air becomes warm before it reaches the floor below, resulting in poor cooling efficiency and the ability to cool the room uniformly. I couldn't do it. In addition, during heating, warm air is once bent at right angles from the air circulation hole in the center of the annular plate to the upper end of the outer air outlet between the outer circumferential surface of the cylinder and the inner circumferential surface of the outlet body, and then the outer air is Because the air is blown vertically downward from the outlet, the speed at which the warm air reaches the floor below is slowed down, or the distance that the warm air reaches the floor is shortened, resulting in poor heating efficiency. It was not possible to heat the room evenly. Furthermore, since the panel body and annular plate are lowered and raised during cooling and heating, the structure is complicated, and the pressure loss increases when warm air bends, making it more likely to cause malfunctions such as increased noise. .

On the other hand, the latter supply/exhaust port device moves the damper up and down to control the air flow rate passing through the gap between the wide part of the casing and the air diffusion plate, so the air flow rate during cooling and heating is However, it was not possible to adjust the direction in which the air was blown out.

Therefore, this idea was devised to solve the above-mentioned problems, and when cooling and heating,
Not only does it make it extremely easy to adjust the air blowing direction, but it also provides excellent cooling and heating efficiency, allows uniform cooling and heating of the room, and lowers the pressure loss of warm air. Therefore, it is an object of the present invention to provide an air blowing direction adjusting device for an air blowing outlet for heating and cooling, which can reduce noise.

(Means for solving the problem) In order to achieve the above-mentioned purpose, this invention has a cylindrical body with a smaller diameter inside the cylindrical outlet body, and the outer peripheral surface of this cylindrical body and the outlet It is supported so that an outer air outlet is provided between the inner circumferential surface of the outlet body, and a disk body having a disk section at the bottom is provided inside the tube body, and the lower end of the tube body and the outer circumferential edge of the disk section are connected to each other. The support tube of the support rod is supported via a screw rod so that an inner air outlet is provided between the two, and a cylindrical air blowing adjustment body with a slightly smaller diameter is installed inside the tube, above the panel. The inner air outlet is vertically movable so that the inner air outlet is opened and closed via a link mechanism in which a swinging rod, a connecting rod, etc. sequentially move when the operating tube of the driving body moves up and down.

(Function) With the above-mentioned technical means, during heating, air is blown out by the rising action of the operating pipe of the drive body, the swinging action of the swinging rod of the link mechanism, and the descending action of the connecting rod. The regulating body is lowered, and the inner air outlet between the lower end of the cylinder and the outer circumferential edge of the panel part of the panel body is closed, and on the other hand, during cooling, the lowering action of the actuating pipe of the driving body is opposite to that during heating. Then, due to the swinging action of the swinging rod of the link mechanism and the rising action of the connecting rod, the air blowing adjustment body rises, and the inner air between the lower end of the cylinder and the outer peripheral edge of the panel of the panel body is Make sure the air outlet is open.

Moreover, during cooling, cold air is blown out vertically downward from the outer air outlet between the inner circumferential surface of the outlet body and the outer circumferential surface of the cylindrical body, and at the same time, the cold air is blown out between the lower end of the cylindrical body and the outer circumferential surface of the cylindrical body. By blowing horizontally to the side from the inner air outlet between the outer peripheral edge of the air outlet, the vertical cool air from the outer air outlet collides with the horizontal cool air from the inner air outlet, Make sure that the cold air is dispersed in an approximately 45 degree direction.

In addition, during heating, warm air is blown out vertically downward from only the outer air outlet between the inner circumferential surface of the outlet body and the outer circumferential surface of the cylindrical body. To increase the speed at which warm air reaches the floor below (approximately twice as fast as during cooling) and increase the distance that warm air reaches the floor.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

As shown in FIGS. 1 to 3, a cylindrical body 2 with a smaller diameter is placed inside a cylindrical outlet body 1 between the outer circumferential surface of this cylindrical body 2 and the inner circumferential surface of the outlet body 1. The cylinder body 2 is supported so that the outer air outlet 3 is provided therein, and inside the cylinder body 2, a disk body 5 having a plate part 4 at the bottom is disposed between the lower end of the cylinder body 2 and the outer peripheral end of the plate part 4. It supports so that the inner air outlet 6 is provided. That is, the cylinder body 2 and the support cylinder 7 of the disk body 5 are arranged inside the outlet main body 1, and the support cylinder 7 has three
The book support rod 8 is connected to the inner peripheral surface of the outlet body 1 and the cylinder body 2.
The nuts 1 are inserted from the air outlet main body 1 side at 120 degree intervals through spacers 9 which have a larger diameter than the support rod 8 and have the same length as the mouth width of the outer air outlet 3.
0, etc., and the support cylinder 7 is made up of a horizontal plate part 4 having approximately the same diameter as the cylinder body 2, and a screw rod 12 fixed to a protrusion 11 at the center of the upper surface of this plate part 4. The body 5 is supported from below by screwing means of a screw rod 12 so as to be vertically movable.

Further, inside the cylinder 2, a cylindrical air blowing adjustment body 13 having a slightly smaller diameter and lower height than the cylinder 2 is installed between the lower end of the cylinder 2 and the outer circumference of the plate part 4 of the plate 5. It is provided above the panel 5 so as to be vertically movable via a link mechanism 15 and a drive body 14 such as a bellows or wax element so that the inner air outlet 6 between the two can be opened and closed.

As shown in an enlarged view in FIG. 3, the driving body 14 supports an upper horizontal plate 28 having a guide hole 27 and a lower horizontal plate 30 having a filling hole 29 on the upper inner peripheral surface of the outlet body 1. The rod 31 and the support rod 32
A bellows-shaped telescopic outer cylinder 34 and a bottomed cylinder are supported at 120-degree intervals and are filled with Freon gas from the filling fitting 33 on the lower side of the lower horizontal plate 30 onto the filling hole 29 of the lower horizontal plate 30. A bellows 36 consisting of a shaped inner cylinder 35 is fixed, and a coil spring 37 is inserted into the bottom surface of the inner cylinder 35 of the bellows 36 and returned from the guide hole 27 of the upper horizontal plate 28 to the lower side of the upper horizontal plate 28.
The lower end of the operating tube 16, which is inserted vertically and movably, is fixed thereto. On the other hand, the link mechanism 15 has support plates 17 erected at intervals of 120 degrees at positions shifted by 60 degrees from each of the support rods 31 and support rods 32 on the upper surface of the upper horizontal plate 28 of the drive body 14,
At the upper end of each support plate 17 is a swinging rod 18 whose one end is supported by the upper end of the operating tube 16 of the drive body 14.
The other end of each swinging rod 18 is configured to pivotally support the upper end of each connecting rod 19 whose lower end is fixed to the upper inner circumferential surface of the air blowing adjustment body 13. It is formed.

Next, to explain the usage condition of the air blowing direction adjusting device of the air conditioning air outlet of this invention, as shown in FIG. By attaching to the connected connecting tube 23 via the attachment piece 24, attachment screw 25, rubber packing 26, etc., the Freon gas in the bellows 36 of the drive body 14 expands during heating, as shown by the dashed line in FIG. By the extension action of the return coil spring 3737 of the bellows 36 against the elastic force, the raising action of the operating tube 16, the swinging action of the swinging rod 18 of the link mechanism 15, the lowering action of the connecting rod 19, etc. , the air blow-off adjustment body 13 is lowered, and the inner air blow-off port 6 between the lower end of the cylinder body 2 and the outer peripheral end of the plate part 4 of the plate body 5 is closed. On the other hand, during cooling, as shown by the solid line in FIG. 1, the freon gas in the bellows 36 of the driving body 14 contracts, contrary to the heating, and the contraction effect due to the elastic force of the return coil spring 37 of the bellows 36 causes the operating tube to descending action of 16,
Due to the swinging action of the swinging rod 18 of the link mechanism 15 and the lifting action of the connecting rod 19,
3 rises, and the inner air outlet 6 between the lower end of the cylindrical body 2 and the outer peripheral end of the plate part 4 of the plate body 5 is opened.

(Effect of the invention) That is, this invention has a cylindrical body 2 with a smaller diameter inside the cylindrical outlet body 1, and between the outer circumferential surface of the cylindrical body 2 and the inner circumferential surface of the outlet body 1. The cylinder body 2 is supported so that the outer air outlet 3 is provided therein, and a disk body 5 having a disk part 4 at the bottom thereof is provided inside the cylinder body 2. The support tube 7 of the support rod 8 is supported via a screw rod 12 so that the air outlet 6 is provided therein, and a cylindrical air blowing adjustment body 13 having a slightly smaller diameter is provided inside the tube body 2.
The inner air outlet 6 is connected to the upper part of the panel body 5 through a link mechanism 15 in which the swinging rod 18, the connecting rod 19, etc. move sequentially when the operating tube 16 of the drive body 14 moves up and down.
Since it is provided so that it can freely move up and down so that it can be opened and closed, during heating, the rising action of the operating pipe 16 of the drive body 14, the swinging action of the swinging rod 18 of the link mechanism 15, and the descending action of the connecting rod 19 are used. Then, the air blowing adjustment body 13 is lowered, and the lower end of the cylinder body 2 and the plate part 4 of the plate body 5 are
The inner air outlet 6 between the outer peripheral end of the inner air outlet 6 and the outer peripheral end of the inner air outlet 6 is closed. On the other hand, during cooling, the driver 1
4, the swinging action of the swinging rod 18 of the link mechanism 15, and the rising action of the connecting rod 19, the air blowing adjustment body 13 rises, and the lower end of the cylinder 2 and the panel The inner air outlet 6 between the body 5 and the outer peripheral end of the board 4 is opened. Therefore, it is extremely easy to adjust the air blowing direction without rotating the disk body and the annular plate to lower and raise them as in the conventional case.

Moreover, during cooling, cold air is placed between the inner circumferential surface of the outlet main body 1 and the outer circumferential surface of the cylindrical body 2 at the outer air outlet 3.
At the same time, the cold air blows vertically downward from the cylinder body 2.
By blowing horizontally to the side from the inner air outlet 6 between the lower end and the outer peripheral edge of the panel part 4 of the panel body 5, the vertical cool air from the outer air outlet 3 and the inner air outlet are The horizontal cold air from outlet 6 collides with the cold air and is diffused in a direction of approximately 45 degrees, so unlike conventional cold air, the cold air is diffused too horizontally to the sides and becomes warm before it reaches the floor below. The cooling efficiency is extremely high, and the room can be cooled uniformly without any problems.

In addition, during heating, warm air is blown out vertically downward only from the outer air outlet 3 between the inner circumferential surface of the outlet body 1 and the outer circumferential surface of the cylindrical body 2, so that there are no obstacles in the way. Therefore, unlike conventional methods, warm air is once bent at right angles from the air circulation hole in the center of the annular plate to the upper end of the outer air outlet between the outer circumferential surface of the cylinder and the inner circumferential surface of the outlet body, and then is transferred to the outside. Without blowing out vertically downward from the air outlet, the speed at which warm air reaches the floor below is faster than before (almost twice as fast as when cooling), and the warm air reaches the floor. Since the distance increases, the heating efficiency is extremely high and the room can be heated evenly.

Furthermore, during cooling and heating, the air blowing regulator 13
It is easy to configure because it lowers and raises only the
The warm air is not once bent at right angles from the air circulation hole in the center of the annular plate toward the upper end of the outer air outlet as in the conventional case, and the pressure loss of the warm air is low and noise can be reduced.

As explained above, according to this invention, it is not only extremely easy to adjust the air blowing direction during cooling and heating, but also the cooling efficiency and heating efficiency are excellent, and the room can be uniformly cooled and heated. It can provide heating, and also has various effects such as reducing noise during cooling and heating.
