Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner, particularly to an improvement of a fluid element provided at an exhaust port of the air conditioner.

Conventionally, as this type of fluidic device, one shown in FIG. 1 has been generally used.

That is, this fluid element allows an airflow of warm or cold air to flow into this fluid element from an inlet 1, first adjusts the airflow at a straight throat part 2, and then applies negative pressure to one side and positive pressure to the other. The control ports 3 and 3' deflect this airflow, thereby switching the outlet of the airflow from the outlet 4 to the outlet 5, or conversely from the outlet 5 to the outlet 4, to enhance the air conditioning effect in the room. Therefore, in order to enhance this air conditioning effect, it was considered preferable to increase the airflow deflection angle α.

However, since this fluid element arranges the airflow of warm or cold air flowing in from the inlet 1 at the linear throat section 2, this airflow is arranged in the same direction vector as the linear throat section 2. As a result, this airflow cannot be largely deflected by the control units 3 and 3', and as a result, the airflow deflection angle α becomes a small value, and even if this fluid element is attached to the exhaust port of the air conditioner, it will not be possible to deflect the airflow to a large extent. The drawback was that the air conditioning effect was not very good.

The present invention has been made to eliminate the above-mentioned conventional drawbacks, and its purpose is to provide an air conditioner with extremely high air conditioning effects.

In order to achieve this objective, the present invention provides a fluid element having an inlet at one end and an outlet at the other end at the exhaust port provided in the main body case that houses the blower inside. is installed facing outward, and the inlet of the fluid element is formed into a single opening by forming a curved surface that has no straight part in the shape of an abrupt pinch that projects inward, and the flow of the fluid element is An airflow diversion device is installed near the inlet.

Hereinafter, the present invention will be explained with reference to FIGS. 2 and 3 showing one embodiment thereof.

In Fig. 2, 6 is the main body case, and this main case 6
A heat exchanger 7 and a cross flow fan 8 as a blower are housed inside.

Here, to explain the reason why the cross-flow fan 8 is used as the blower, the airflow generated by the cross-flow fan 8 has a smaller flow velocity variation than the airflow generated by a sirocco fan or a propeller fan. less,
This is because the flow velocity distribution is relatively uniform.

Reference numeral 9 represents a front gnore provided on the front surface of the main body case 6, and reference numeral 10 represents a filter.

Reference numeral 11 denotes a ventilation guide provided so as to surround the cross flow fan 8. One end of this ventilation guide 11 is attached to the heat exchanger 7, and the other end is arranged at the rear of the exhaust port 6a provided in the main body case 6. There is.

12 is a fluid element provided with an inlet 12a at one end and an outlet 12b at the other end, and this fluid element 12 is connected to the main body case 6.
The inflow port 12a is connected to the other end of the ventilation guide 11 at the exhaust port 6a provided in the fluid element 12, and the structure of this fluid element 12 is as shown in FIG.

That is, in this fluid element 12, the airflow deflection walls 12C, 12C' connecting the inlet 12a and the outlet 12b are curved surfaces, and the airflow deflection walls 12C, 12C near the inlet 12a are formed with curved surfaces. ' is provided with a control port 14.15 for the airflow deflection device 13.

Further, in detail, in this fluid element 12, from the inlet port 12a to the control port 14.15, the distance between the inlet port 12a and the control port 14.15 is formed by a curved surface having no sharp inwardly protruding straight line portions such that the interval gradually narrows. On the other hand, the airflow deflection walls 12C and 12C' from the control port 14.15 to the outlet 12b are formed with curved surfaces such that the interval between them is wide, and the airflow deflection walls 12C and 12C' are formed with curved surfaces such that the gap between them becomes wide. Then, the airflow of warm or cold air that has flowed through the exhaust guide 11 is directed to the inlet 1.
2a, the airflow that enters this fluidic element 12 is no longer arranged into a unidirectional vector, and the flow is deflected away from the position of the inlet 12a.

The flow of hot or cold air is therefore largely deflected by the control ports 14.15.

Thereafter, this airflow is directed to the airflow deflection wall 12C or 120' formed with a curved surface to increase the airflow deflection angle β.
, and thus the airflow deflection wall 12C or 1
The airflow flowing along 2C' flows through the outlet 12 of the fluid element 12.
It is largely deflected and flows out from b into the room.

The airflow deflection device 13 includes control ports 14.15 and diaphragm portions 16. provided on the sides of these control ports 14.15.
17, a four-way valve 18 connected to the diaphragm parts 16a, 17a of these diaphragm parts 16.17, and a positive pressure source 19. connected to the four-way valve 18. It is composed of a negative pressure source 20.

When the airflow deflection device 13 connects the positive pressure source 19 to the diaphragm chamber 17a and the negative pressure source 20 to the diaphragm chamber 16a by switching the four-way valve 18, the air inlet 14a of the control port 14 is opened. , conversely, control port 15
The atmospheric air inlet 15 a is closed by a membrane 17 b provided on the diaphragm portion 17 , so that the control port 15 has a relatively negative pressure than the control port 14 .

As a result, the airflow flowing in from the inlet 12a of the fluid element 12 flows along the airflow deflection wall 12C'.

Further, in this case, the airflow flowing along the airflow deflection wall 120' becomes attached to the airflow deflection wall 12C'.

This is because the cross-flow fan 18 is used as the blower, and the airflow generated by the cross-flow fan 18 has a relatively uniform flow velocity distribution with little variation in flow velocity.

In this way, the airflow with a relatively uniform flow velocity distribution with a small amount of variation in flow velocity is easily deflected by the control port 14.15 of the airflow deflection device 13, and as a result, this airflow is
It becomes attached to C'.

In addition, the four-way valve 18 is switched to provide a positive pressure source 19 to the diaphragm chamber 16a and a negative pressure source 2 to the diaphragm chamber 17a.
0 is connected and the air inlet 14a of the control port 14 is closed with the membrane 16b provided on the diaphragm portion 16, the airflow flowing in from the inlet 12a of the fluid element 12 is as follows.
The air is deflected by the control ports 14, 15 of the airflow deflection device 13 and flows while adhering to the airflow deflection wall 12C.

Next, the operation of this embodiment will be explained.

The air that enters the main body case 6 from the front grille 9 through the filter 10 by the cross flow fan 8 passes through the heat exchanger 7 to become a hot or cold airflow, and then this airflow passes through the ventilation guide 11 and becomes a fluid. It enters the inlet 12a of the element 12.

When the airflow that has entered the inlet 12a passes through the control port 14.15 of the airflow deflection device 13, the diaphragm section 17 and the positive pressure source 29, the diaphragm section 16 and the negative pressure source 20 are connected, and the control port If the pressure at 15 is relatively lower than the pressure at control port 14, arrow A in FIG.

If the pressure in the control port 14 is lower than the pressure in the control port 15 by switching the four-way valve 18, the pressure is largely deflected in the direction of arrow B in FIG.

Specifically, when cooling a room, that is, when cold air is entering the fluid element 12, the diaphragm section 17 and the positive pressure source 19, the diaphragm section 16 and the negative pressure source 20 are connected, This cold air flows out to the lower part of the room as shown in the arrow hole in FIG.
8, the diaphragm part 17 and the negative pressure source 20,
If the diaphragm portion 16 and the positive pressure source 19 are respectively connected and the warm air is allowed to flow downward into the room as shown by arrow B in FIG. 2, the heating and cooling effect of the room will be significantly improved.

Another way to use it is to deflect the airflow depending on the amount of airflow that enters the fluid element 12. To explain this specifically, for example, if the amount of warm air is too large, If this warm air is applied directly to a person's body, the person may feel colder, and in such cases, the airflow is deflected to prevent it from hitting the body.

As described above, the air conditioner of the present invention has, at its exhaust port, an inlet having a curved surface that does not have a straight part with a sharp pinch shape projecting inward, and an airflow deflection wall having a curved surface with a widening shape. Moreover, since the airflow deflection wall near the inlet is equipped with a fluid element equipped with an airflow deflection device, it is possible to greatly deflect the airflow of cold or warm air, significantly increasing the indoor air conditioning effect. The fluid element can also be made more compact.
