Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a blowout structure for an air conditioner, and more specifically, to a blowout structure for an air conditioner that takes in room air and blows out conditioned air from an outlet. .

(Prior Art) Conventionally, as a blowout structure for an air conditioner, the one described in, for example, Japanese Utility Model Application Publication No. 116918/1983 is known, and the structure described in this publication is as shown in FIG. A suction port 2 and a blowout port 3 are formed in the front part of the main body casing 1 in which the fan 4 and the heat exchanger 5 are installed, respectively, and a wind direction adjustment plate H that determines the direction of the blowout conditioned air is attached to the blowout port 3. Supports freedom of movement.

When performing indoor air conditioning in this way, the main body casing 1 is fixedly supported on the indoor wall surface,
By rotating the fan 4, indoor air is taken into the main body casing 1 from the suction port 2, heat exchanged with the heat exchanger 5, and the air is transferred from the air outlet 3 to the wind direction adjustment plate. Conditioned air is blown out in the wind direction determined by H.

(Problems to be Solved by the Invention) However, with the above-described blowout structure of the air conditioner, the following problems arose, especially when performing heating operation.

That is, generally when performing a heating operation with the air conditioner, the wind direction adjustment plate H is swung downwardly and hot air is blown out from the air outlet 3 directly downward toward the floor surface of the room. This is desirable, and by doing so, it is possible to warm the occupant's feet intensively, creating a comfortable heating environment where the head is cold and the feet are warm.

However, when heating a relatively large room,
The airflow direction adjustment plate H is swung and adjusted diagonally forward so that the warm air blown out from the air outlet 3 is distributed throughout the room. There was a problem that the floor surface near the installation location was not sufficiently warmed, and the warm air hit the residents' faces directly, causing discomfort to the residents, which was the opposite of the so-called cold head and warm feet described above. be.

The above will be explained based on the temperature distribution graph shown in FIG.

The temperature distribution graph in Figure 10 shows that the main body casing 1 is installed at a height of 1.8 m from the floor of the indoor wall, and the wind direction adjustment plate H is set at a 45 degree angle diagonally forward with respect to the indoor wall. It also shows experimental data showing the temperature distribution regions for a 6-tatami room (Zone A in the diagram) and a 10-tatami room (Zone B in the diagram) when the room heating reference temperature is set at 24.6°C. .

In addition, in the above figure, the average indoor temperature distribution area is shown by a curve with a 0 sign, and a curve with a +1 sign for each 1°C increase from the average temperature, and a curve with a +1 sign for each 1°C increase from the average temperature.
The curve shows the temperature distribution area of the entire room with a -1 sign for each 1°C decrease.

As is clear from Figure 10 above, in the area of Zone B beyond Zone A, a temperature distribution curve of +1 is formed in the lower region of the room, resulting in a cold head and foot temperature, creating a relatively good heating environment. On the other hand, in the area of the A zone, the temperature distribution curve with the 0 sign is formed over a wide area from the lower part of the attachment position of the main body casing 1 toward the front floor side of the room, Temperature distribution curves with -1, -2 and -3 signs are formed below the temperature distribution curve with 0 sign. In other words, these low temperature temperature distribution areas are located below the installation position of the main body casing 1. It is formed over a wide area throughout the room, and in the area of the A zone, the feet of the occupant are not sufficiently heated, resulting in a poor heating environment, and the low-temperature air is blown directly onto the occupant's face. , there was a problem that it gave residents a feeling of draft.

The present invention was devised in view of the above-mentioned problems, and its purpose is to disperse the air from the air outlet into the interior of the room so that it can be comfortably blown out even in a large room. The purpose of the present invention is to provide a blowout structure for an air conditioner that can provide a comfortable heating environment.

(Means for Solving the Problems) The present invention is a blowout structure for an air conditioner that takes in indoor air and blows out conditioned air from the blowout port 3, as shown in the embodiment of the drawings. , the air outlet 3 supports a main flap 6 that determines the direction of the air blown from the air outlet 3, and receives a part of the air blown toward the main flap 6 to change the direction of the air. An auxiliary flap 7 is formed which includes a wind direction changing part 7a that allows air to flow to the main flap 6, and a passage part 7b that allows air to flow to the main flap 6, and the auxiliary flap 7 is supported so as to be able to change its angle with respect to the main flap 6. It is characterized by this.

(Function) However, when heating a large room,
By swinging and adjusting the main flap 6 and the auxiliary flap 7 to a predetermined angle, the flaps 6 and 7 disperse and blow out the air from the air outlet 3 into the room, thereby blowing out the entire room. This improves the temperature distribution and provides a comfortable heating environment.

(Example) The blowout structure of the air conditioner according to the present invention will be described below with reference to the embodiments shown in the drawings.

FIG. 1 shows a wall-mounted air conditioner installed on the indoor side of a separate type air conditioner, in which a suction port 2 is provided on the front side of a main body casing 1 that is fixedly supported on the indoor wall surface, and the main body casing 1 A fan 4 and a heat exchanger 5 are provided inside the main casing 1, and as the fan 4 rotates, the suction port 3 is formed on the lower surface side of the body casing 1.
The indoor air taken into the main body casing 1 is heat-exchanged by the heat exchanger 5 and is blown out from the air outlet 3 to the indoor side.

In the above air conditioner, as clearly shown in FIG. The auxiliary flap 7 is formed with a wind direction changing part 7a that receives a part of the blown air and changes the wind direction, and a passage part 7b that allows the air to flow to the main flap 6. 7 is supported on the main flap 6 so that its angle can be changed.

More specifically, as shown in detail in FIG. 3, the main flap 6 is formed of a blind elongated plate extending along the length of the air outlet 3, and the auxiliary flap 7 is The main flap 6 is made of a plate material with a length similar to that of the main flap 6, and a plurality of rectangular opening windows are provided at predetermined intervals in the middle part of the plate material in the longitudinal direction. The wind direction changing section 7a is formed by a blind section provided between each of the opening windows.

In addition, on both sides of the main flap 6 in the length direction, support pieces 6 are provided at the proximal end portions of the main flaps 6 on the support side toward the air outlet 3, respectively.
a are integrally provided in a protruding manner, and mounting holes 6b are opened in each of the support pieces 6a, and each of the support pieces 6a is provided at the proximal end of the support side toward the air outlet 3 on both sides of the auxiliary flap 7 in the length direction. The protruding rods 7c to be inserted into the mounting holes 6b of the support piece 6a are provided integrally in a protruding manner, while each of the protruding rods 7c is rotatably provided on the opening walls 1a formed on both sides in the length direction of the air outlet 3. Support holes 1b for supporting are formed respectively.

Then, each of the projecting rods 7c provided on the auxiliary flap 7 is relatively rotatably inserted into the mounting hole 6b of each support piece 6a provided on the main flap 6, and the By inserting the ends of the respective projecting rods 7c into the support holes 1b of the respective opening walls 1a, the main flap 6 and the auxiliary flap 7 are supported so as to be able to change their respective angles around the respective projecting rods 7c. It is.

As described above, the main flap 6 is connected to the air outlet 3.
When the auxiliary flap 7 and the auxiliary flap 7 are supported so as to be able to swing on the same axis via a protrusion 7c provided on the auxiliary flap 7, it is easy to control the angle of each of the flaps 6 and 7 using a single stepping motor or the like. It will become.

Further, as shown in FIG. 4, the auxiliary flap 7 has an end portion opposite to the support side proximal end to the air outlet 3 cut out in a roughly uneven shape, and the air passage portion 7b on the side of the cutout recess. Alternatively, the convex portion side may serve as the modified portion 7a.

Next, the operation of the blowout structure constructed as above will be explained.

First, when heating a large room with the air conditioner, the main casing 1 is fixedly supported on an indoor wall surface, and the air outlet 3 of the casing 1 is
The main flap 6 supported on the main flap 6 is shown in FIGS.
As shown in the figure, the auxiliary flap 7 is inclined approximately 45 degrees toward the front of the room relative to the wall surface, and the auxiliary flap 7 is oriented downward substantially parallel to the wall surface.

By doing so, the hot air blown out from the blow-off port 3 as the fan 4 rotates is alternately dispersed by the flaps 6 and 7 and blown into the room. flap 7
A part of the warm air that has passed through the passage section 7b is blown out along the main flap 6 at an angle of about 45 degrees, as shown by arrow A, and collides with the wind direction changing section 7a of the auxiliary flap 7. A part of the heated air is blown out almost directly downward toward the floor of the room, as shown by arrow B.

In this case, the hot air flowing from the fan 4 to the outlet 3 is only divided alternately into two directions indicated by A and B in the figure by the two flaps 6 and 7, and the hot air ventilation area is The flap itself is in a state in which the flaps 6 and 7 are overlapped, that is, it is almost the same as a single flap as in the conventional case, and the ventilation path cannot be reduced or expanded during the above-mentioned distributed blowout. Since there is almost no
This prevents the wind speed of hot air blown from the air from changing significantly and maintains a comfortable wind speed.

Next, a temperature distribution graph when heating operation is performed with the angles of the flaps 6 and 7 set as described above will be explained based on FIG. 8.

The temperature distribution graph shown in FIG.
7 is set in the state shown in FIG. 1, that is, the main flap 6 is tilted diagonally forward at an angle of 45 degrees with respect to the indoor wall surface, and the auxiliary flap 7 is set parallel to the wall surface and almost directly below the floor surface. While setting in the direction,
6 when the room heating standard temperature is set to 24.6°C
Experimental data showing each temperature distribution area for a tatami room (Zone A in the diagram) and a 10 tatami room (Zone B in the diagram) is shown.

In addition, in the above figure, as in the case of Fig. 10 mentioned above, the average temperature distribution area of the room is shown by a curve with a 0 sign, and for every 1°C rise from the average temperature, +1
The temperature distribution area of the entire room is shown by a curve with a sign, and a curve with a sign of -1 for each 1°C lower than the average temperature.

As is clear from the above FIG. 8, in the area of the B zone beyond the A zone, the 10th
As in the case shown in the figure, the +1 temperature distribution curve is located in the lower range of the room, resulting in a cold head and warm feet, resulting in a good heating environment.

In addition, in the area of the A zone, the temperature distribution curve with the 0 symbol is formed only in a narrow region below the mounting position in the main casing 1, and in an extremely narrow region below the temperature distribution curve with the 0 symbol, Temperature distribution curves with signs of -1, -2 and -3 are formed, that is, these low temperature temperature distribution regions are formed only in an extremely narrow region compared to the case of FIG. The heating area by the warm air blown out from the air outlet 3 spreads over a wide area throughout the room, and even in the area of the A zone, the feet of the occupant can be sufficiently heated, creating a good heating environment. Moreover, low-temperature air is no longer blown directly onto the occupant's face, and the problem of giving the occupant a drafty feeling is also resolved.

The flaps 6 and 7 are not only used as the dispersion blowout described above, but also as shown in FIGS. By adjusting the swing at the outlet 3, it is also possible to use it in the same way as a conventional one.

In other words, when the system shown in Figure 5 is used in a relatively small room, warm air is blown downward toward the floor when the heating is stable, creating a comfort zone from directly below the air conditioner. .

In addition, in the case shown in Fig. 6, when the air volume of fan 4 is set to ultra-light air at the time of starting heating,
By reducing the ventilation area of the air outlet 3, it is possible to improve the start-up of operation and eliminate the draft feeling at the start-up. Furthermore, it can also be used as a cover for the air outlet 3 when the operation is stopped.

Furthermore, in the case shown in FIG. 7, the air is blown out in a horizontal direction during cooling, and cold air can be supplied over a wide area.

(Effect of the invention) As explained above, in the air conditioner blowout structure according to the present invention, the main flap 6 that determines the direction of the blown air blowing out from the blowout port 3 is supported at the blowout port 3 provided in the main body casing 1. At the same time, the auxiliary flap includes a wind direction changing section 7a that receives a part of the blown air blown toward the main flap 6 and changes the wind direction, and a passage section 7b that allows the air to flow toward the main flap 6. Since the flap 7 is formed and the auxiliary flap 7 is supported so as to be able to change its angle with respect to the main flap 6, when heating a large room, the main flap 6 and the auxiliary flap 7 can be By adjusting the swing to a predetermined angle, the flaps 6 and 7 can disperse and blow out the air from the outlet 3 into the room, improving the temperature distribution throughout the room. This made it possible to obtain a comfortable heating environment.
