Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner, and particularly to an air conditioner that obtains pie-level mode blown air.

Generally, cold air that has passed through a cooling heat exchanger (evaporator) is mixed with warm air that is heated by passing a portion of this cold air through a heating heat exchanger (heater), or a heat air mix type is used. Air conditioners cannot clearly separate the air from the mixing chamber into cold air and warm air when the so-called pie-level state occurs, making it difficult to obtain pie-level mode air with cold heads and warm feet.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner that eliminates the above-mentioned drawbacks and allows pie-level mode air to be easily obtained from a mixing chamber.

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

FIG. 1 shows a cross-sectional plan view of an embodiment of the air conditioner according to the present invention, and FIG. 2 shows a partially cutaway perspective view thereof.

Air taken in through the suction port 1 is blown by a proa fan 3 connected to a motor 2, cooled by an evaporator 4, and then distributed in two directions by two temperature control valves 5 and 6.

A part of the cold air is introduced directly into the mixing chamber 8 through a grill 9 formed at the entrance thereof, and the other part passes through the heater 7 and is heated appropriately and is formed at the entrance to the mixing chamber 8 as warm air. It is introduced through the grill 10 that has been cleaned.

The mixing ratio of the cold air and warm air introduced into the mixing chamber 8 is appropriately adjusted depending on the opening degrees of the two temperature control valves 5 and 6.

The surfaces of the grills 9 and 10 of the mixing chamber 8 face into the mixing chamber 8 at right angles as shown in the figure, or at any angle where the surfaces intersect with each other, so that the cold air passing through both the grills 9 and 10 The warm air intersects within the mixing chamber 8.

Each grill 9, 10 includes a plurality of loopers 11, 12 arranged parallel to the wind path, and each vertical looper 11.12.
It consists of a plurality of movable horizontal loopers 13 and 14 individually arranged between the loopers 12 and 12.

The horizontal loopers 13, 14 are of the same height and are pivoted on their sides in the side plates 17, 18 of the device by pins 15, 16 which pass through the vertical louvers 11, 12 at one point close to the mixing chamber 8.

In addition, movable rods 19.20 are installed in each of the loopers 13.14 at a position farther from the mixing chamber 8 on the side, and these movable rods 19.20 are installed on the side plates 17, 18 and are long in the vertical direction. They fit through the arc-shaped notch grooves 21 and 22, respectively.

When the movable rod 19.20 is slid up and down along the notched groove 21.22, the horizontal looper 13.14 swings about the pin 15.16 and tilts downward or upward in the direction of the wind path. It has become.

The floor 23 of the mixing chamber 8 is located at a position farther from the surfaces of the grills 9 and 10.
In addition, there is an air outlet 2 that communicates with the passenger's feet inside the vehicle.
5 is provided, and a ceiling 24 facing this air outlet 25 is provided.
An air outlet 26 is provided at a position that communicates with a ventilation hole located relatively upward in the vehicle interior.

Now, when the horizontal loopers 13 and 14 of both grills 9 and 10 are both horizontal, the cold air and warm air enter the mixing chamber 8 straight in parallel with the floor 23 and ceiling 24 and are mixed uniformly. Blow air of the same appropriate temperature is sent to the blow-off ports 25 and 26.

Next, when trying to obtain air in the pie level mode, the movable rod 19 of the grill 9 on the cold air side is pushed down in the direction of the arrow 6, toward the need, and the movable rod 20 of the grill 10 on the warm air side is pushed up in the direction of the arrow.

As a result, the horizontal louver 13 of the grill 9 on the cold air side is inclined upward with respect to the mixing chamber 8, and the horizontal louver 14 of the grill 10 on the warm air side is inclined downward with respect to the mixing chamber 8. do.

Therefore, when the cold air passes through the grill 9, it enters the mixing chamber 8 upward along the slope of the horizontal louver 13 as shown by the white arrow in FIG.

Also, when the warm air passes through the grill 10, the horizontal louvers 1
4, it enters the mixing chamber 8 downward as shown by the black arrow in FIG.

In addition, the cold air from the grill 9 is released from the air outlet 2 at the same temperature.
6, but a portion of the grill 10 is inside the mixing chamber 8.
As the cold air intersects with the warm air, it mixes with the warm air and is slightly warmed, and is sent to the outlet 26 as a comfortable cool breeze.The warm air partially mixes with the cold air, but the majority of the people are sent to the outlet at a warm temperature. 25, and as a result, comfortable pie-level mode air is blown out through the air outlets 25 and 26.

In addition, in this example, the movable louver is a horizontal louver, but
Depending on the arrangement of the evaporator and heater, the movable louver may be a vertical louver, and the first movable louver may be used accordingly. The second outlet may be set appropriately.

Also, the vertical louvers of both grills formed in the mixing room are formed at equal intervals, but if the louvers on the side where both grills intersect are widened and narrowed on the side farther from the intersecting side, hot air and cold air This is convenient when mixing.

This is because it is difficult for the cold air and warm air that flow into the mixing chamber from the side where both grills intersect from each other to mix, so the air resistance on the side where both grills intersect is made smaller, and the main air flows into the mixing chamber from here. can be done.

As described above, according to the air conditioner according to the present invention, movable grilles are formed at the two inlets of the mixed and nitrogen-containing airways provided so that cold air and warm air intersect, and each air conditioner is heated in the pie level mode. Since the grille is inclined toward the air outlets provided at two opposing positions, it has the advantage that two types of blown air having an appropriate temperature difference can be easily obtained from the mixing chamber.
