Abstract

PURPOSE:To improve the comfortableness by arranging an adjusting door at the end of main flow path connected with a splitted flow path having individual air mix door through a heater core thereby enabling adjustment of air flow through each branch path. CONSTITUTION:The air passed through an evaporator 21 is distributed by an adjusting door 4 to each branch flow path 3. Said door 4 is operated by a control panel not shown. The air distributed to each branch flow paths 3, 3 is controlled independently by an air-mix door 34 provided individually to produce conditioned air having random temperature. With such structure, the air flow ratio between each branch flow path can be varied to improve the comfortableness.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner in which a main flow path is followed by a divided flow path, and a heater core and each divided flow path is provided with an air mix door.

Such an air conditioner guides conditioned air to various locations through divided channels, and adjusts individual air mix doors to obtain conditioned air according to each divided channel.

There are many conventional air conditioners for automobiles, such as those shown in FIGS. 1 and 2, for example.

That is, a suction section (1) blower 04) having an outside air intake port 0z), an inside air intake port 0z, and an inside/outside switching door 03) is provided, and behind the blower circle there is a main flow path (2) in which an evaporator CD is installed, followed by a A divided flow path (3) that divides this into two,
(3) is forming. The divided flow paths (3) and (3) correspond to the left and right sides of the vehicle compartment, respectively, and the lower air outlet C3+)
and an upper air outlet C32) are opened. A heater core Q is disposed at the entrance of the divided flow path (31, (3)) so as to straddle both the two-way paths.Divided flow path (3).

(3) is individually provided with an air mix door t34) that adjusts the amount of back air to the heater core □□□.
The divided flow path (3) is connected to the main flow path (2) via the heater core α (4) and the air mix door (B).

If we focus on one of the divided channels (3), as shown in Figure 2, the air mix ratio is fixed depending on the angle of the air mix door 0.v, and it is unique to the other divided channel (3). However, in such conventional air conditioners, the divided flow path (3), (
Although it is possible to independently adjust the air mix ratio and set the conditioned air temperature in 3), each divided flow path (3),
Although the air volume ratio to (3) should always be constant, it is also possible to create a difference in the air volume between divided channels (3) and (3) depending on the preference of the seated person or sunlight conditions. figure,
In particular, as shown in Figure 2, when the air mix door (B) is set at the position shown by the two-dot chain line, the conditioned air is not passed through the heater core, and the adjustment is performed using the blower α.
In this case, changing the air volume of one divided flow path (3) will inevitably affect the other, and even if one is comfortable, the other may be uncomfortable. There was a problem.

The present invention has been made in view of these conventional problems, and an object of the present invention is to solve the above problems by making it possible to adjust the air volume ratio of each divided flow path.

In order to achieve such an object, in the present invention, an adjustment door is provided at the end of the main flow path to change the distribution ratio of the air conditioned air flowing from the main flow path to each divided flow path, and the flow rate is controlled at the entrance of the divided flow path. 2; The distribution ratio of the ¥ style air can be adjusted.

Hereinafter, one embodiment of the present invention will be explained based on the drawings. Incidentally, parts similar to those in the conventional example are given rho symbols, and redundant new developments are omitted.

3 and 4 show an embodiment of the present invention,
The terminal part of the main water path (2) and the evaporator (2+1
Behind the air mix door QA+, before the air mix door QA+, change the west distribution ratio of the air conditioned air flowing to the split flow path (3), (3) via the near mix door head) or the heater core (c).
l? This is a book with an adjustable door (4).

The OA adjustment door (4) is an air mix door C'rA;),
Near the front end of the CW+ boundary G51 and the main flow path (2)
The base end is pivotally supported in the center of the air mix door (341, 941 through a rejection shaft (A1) perpendicular to the rotation axis It can be moved and stopped at any angle.

Figure 4 shows the control panel (5), in which the panel plate (5) has a slit (51).
An adjustment knob (52) is used from there, and a sign (53) is displayed along the slit (5]) indicating the left and right air volume by the width of a tapered band mark. Adjustment knob (
In the diagram 521, the left and right movement is linked to the swinging of the adjustment door (4). That is, the adjustment knob (52) is connected to the adjustment door (4) via a lever, cable, or the like.

In the air conditioner having the above configuration, the divided flow path (3),
(3) In addition to being equipped with individual air mix doors (2) to independently set the air mix ratio and obtain conditioned air at any temperature, the conditioned air that has passed through the evaporator (21) is controlled by the adjustment door (2). 4) and divided flow paths (3),
(3). That is, when the adjustment knob (52) of the control panel (5) is moved, the adjustment door (4) is rotated in accordance with the amount of movement. When the adjustment knob (52) is stopped at a desired position, the adjustment door (4) is also stopped. At this time, the main channel (2) is partitioned by the position of the tip (421) of the adjustment door (4), and the divided channel (3),
Conditioned air flows from the opening on the side corresponding to (3) to the divided flow path (3) according to its area. Thus, the split channel (3)
The air volume is determined by the adjustment door (4).

In other words, in each divided flow path (3), the air mix ratio is independently adjusted to determine the temperature of the conditioned air, as in the conventional case.

In the above embodiment, the divided flow channels are shown to correspond to the left and right sides of the vehicle interior, but the main flow channel may be divided into the front and rear of the vehicle interior and other areas to lead into the house as appropriate. Of course, the cross-sectional area or structure may be different.

According to the air conditioner according to the present invention, since each divided flow path can be adjusted to have separate air conditioned air temperature and air volume, desired air conditioned air can be obtained in various parts of the room, and one By making one area comfortable, inconveniences such as discomfort in other areas will not occur, and a finely tuned and comfortable air conditioning condition can be obtained. In addition, if the adjustment door can be used to stop the air conditioned air flowing to one divided flow path, it is possible to intensively flow 9 conditioned air to the other divided flow path for immediate air conditioning control. become.
