Description

[Detailed description of the invention] This invention relates to an air conditioner for an automobile that controls the air temperature inside a vehicle, and can independently control the air temperature of the air outlets provided for the left and right seats. The purpose is to provide air conditioning equipment.

In conventional automotive air conditioners, the air temperature at the outlet is controlled by a single outlet air temperature control device, and the temperature of the air at the outlet is controlled by a single outlet air temperature controller.
Air at the same temperature is blown out, or air at different temperatures is blown out if air conditioning is not sufficiently performed.

Therefore, the air temperature at the left and right outlets may differ if the required comfort temperatures of the occupants in the left and right seats are different, if the heat load on the occupants in the left and right seats is different due to sunlight hitting the vehicle from the side, or if there is a malfunction in the air conditioning system, etc. In many cases, passengers in either the left or right seat are forced to compromise on comfort.

The present invention was developed to solve the above-mentioned problems, and in an air mix type air conditioner, the air conditioning passage in the air conditioner body is divided into two passages, and the air in these passages is blown into left and right sides. The air is sent to the left and right seats separately from the exit, and the temperature of the air can be controlled independently for each of the two passages, so that each passenger in the left and right seats can freely obtain a comfortable temperature.

Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing an embodiment of the automotive air conditioner of the present invention.

In the figure, reference numeral 1 denotes the main body of the air conditioner. On the upstream side, that is, on the cooler side, a heater core 2 is arranged horizontally in the lower half of the main body 1, tilting in the airflow direction. Air outlet ports 3aw3b are arranged side by side on the left and right.

The heater core 2 is located downstream of the heater core 2 in the main body 1.
An L-shaped partition wall 4 vertically provided at a position dividing the air into two parts in the width direction allows two air conditioning passages 5a for the left side to communicate with the air outlet 3a and an air conditioning passage for the right side 5b to communicate with the air outlet 3b.
On the upstream side of these two passages 5a and 5b, that is, on the upper side of the front surface of the heater core 2, which serves as the air inlet to both roads, there is a mechanical damper 6a that independently controls the air temperature. , 6b are provided.

The air mix dampers 6a and 6b control opening and closing between two positions: a position where the heater core is fully closed, and a position where the air passage in the upper half of the heater core is fully closed and the entire amount of air flowing in from the air inlet is passed through the heater core. be done.

As shown in FIG. 2, the air mix dampers 6a and 6b have a pipe shaft 7a of the damper 6a and a shaft 7b of the damper 6b inserted concentrically, and are rotated separately by levers 8a and 8b at the end of each shaft. It is designed to be operated dynamically.

Further, in this embodiment, a VENT direction outlet 3a is provided in each of the left and right air conditioning passages 5a, 5b.

3b and the DEF direction outlet 9 only in the left side air conditioning passage 5a.
A is shown, and other air outlets are omitted, but both passages 5a and 5b are provided in the HEAT direction and the DEF direction, similar to other embodiments (FIG. 3) to be described later. Needless to say, this can be achieved by adding an air outlet.

In the device of the present invention configured in this way, the air is sent into the main body 1 from the cooler, and the air mix dampers 6a, 6
The air whose temperature has been adjusted by b is completely separated by the partition wall 4, and the air for the left side passes through the air conditioning passage 5a for the left side, as shown by the chain arrow in the figure, and enters the air outlet for the left side (

The other right-side air passes through the right-side air conditioning passage 5b as shown by the dotted arrow and reaches the right-side air outlet (VE).
NT direction) are sent separately from 3b.

Moreover, this air temperature can be freely controlled by the damper 6at6b.

FIG. 3 shows an embodiment of the present invention in which a heater core is provided vertically within the air conditioner main body.

In this case, the heater core 12 is arranged vertically in one half of the air conditioner main body 11 in the vertical direction, and at an appropriate angle from a plane perpendicular to the airflow so that the side facing the center is located in the downstream direction of the airflow. will be placed.

Downstream of the heater core 12, there are a partition wall 14 provided horizontally at a position where the core 12 is divided into upper and lower halves, and partition walls 14a, 14b, 14 extending vertically near the end of the main body 11.
c, on the heater core 12 side, the air passage is divided into a left air conditioning passage 15a at the bottom and a right air conditioning passage 15b at the top.
At the end of the main body 11, each air conditioning passage is extended vertically by the straight wall so as to correspond to each air outlet provided in the main body 1, and a passage 15a is formed vertically. On the left side, the passages 15b are arranged horizontally to the right side, and each air outlet, that is, the VENT direction outlet 13a
t13b, HEAT direction outlet 20a, 20
b, communicates with the DEF direction air outlet 19a, 19b,
As in the case of FIG. 1, air mix dampers 16a and 16b are provided on one side of the front surface of the heater core 12, which serves as the air inlet to the left and right air conditioning passages 15a and 15b, to independently control the air temperature. ing.

Also with the configuration of this embodiment, the air that is sent into the main body 11 from the cooler and whose temperature is adjusted by the air mix damper 16ai6b is transferred to the partition walls 14t 14a, 14b,
14c, and the air for the left side passes through the air conditioning passage 15a for the left side, as shown by the chain arrow in the figure, and the air for the left side (VE NT force direction 3a, HE
The other right-side air is sent out from the right-side air outlet (VENT direction 13b) through the right-side air conditioning passage 15b as shown by the dotted line arrow.
, HEAT direction 20b t DEF direction 19b), and the temperature of the air is also freely controlled by dampers 16a and 16b, as in the case of FIG.

As mentioned above, the present invention provides an air mix type air conditioner in which the air conditioning passage within the main body of the air conditioner is divided into two parts by a partition wall.
The air in these two passages is separately sent out from the left and right outlets, and both passages are equipped with dampers that independently control the air temperature. , and can be freely controlled, so even if the required temperature for the comfort of the left and right (driver side and passenger side) passengers differs, each person can freely obtain a comfortable temperature by operating the damper. This not only significantly improves the passenger's comfort level with respect to temperature, but also has excellent effects as an air conditioner for automobiles, as the device itself is simple and the heater core can be freely selected vertically and horizontally depending on the type of vehicle.

In addition, the two air mix dampers have a shaft structure in which one pipe shaft is inserted into the other shaft, so even though two different shafts are provided, the bearing part is the main body. It is sufficient to receive the bearing portions on both side walls, and the intermediate bearing portion can be omitted, which has the effect of simplifying the bearing structure.
