Abstract

PURPOSE:To perform the cooling and the hot air exhausion through the inner air circulation and the outer air by means of single device, by providing an inner/outer air exchange damper at the I/O port of the blower while arranging an evaporator in the inner air side duct connected to the delivery portion. CONSTITUTION:The inner/outer air exchange damper 8 at the air-feed section of the blower 4 will close the inner-air feed port 1, and when the inner/outer air exchange damper 9 at the delivery section 12 will close the outer-air supply duct 6 side the outer-air will pass through the blower 4 and the evaporator 5 to be cooled and blown out through the diffuser 2 in the cabin. While when the dampers 8, 9 will close the outer-air supply duct 6 side and the outer-air suction 6 side respectively, the cooling through the inner-air circulation is performed. When the dampers 8, 9 will close the outer-air supply duct 6 side and the inner-air side duct 7 respectively, the air will flow through the air-supply port 1 in the cabin 10 to the blower 4 thus to exhaust the hot-air in the cabin quickly through the duct 6 to be used for the exhaustion of the hot-air to the outside.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner for an automobile that exhausts hot air and cools the interior of an automobile.

Conventionally, automotive air conditioners have either a dedicated cooler or a combination of a cooler and an air purifier for the purpose of cooling the rear seats. [There is. In addition, hot air from the rear seats is exhausted to the outside of the vehicle by a Proa-only device installed at the rear of the rear seats.

Therefore, the rear seats cannot be cooled by introducing outside air. Additionally, the device for discharging hot air inside the vehicle and the device for cooling the rear seats cannot share a common depot, duct, etc., and must be installed separately for each device.

The present invention has the above-mentioned point KIl! The air introduction section of the proar is connected to each duct that communicates with the inside and outside air, and an internal and external air switching damper is provided to open and close each duct, and the discharge section of the proa also communicates with the inside and outside air. A separate internal/external air switching damper is provided that connects each duct and opens and closes each duct.

By disposing an evaporator in the middle of the inside air side duct of the discharge part of the proa, six types of modes can be selected: exhausting hot air from the vehicle interior, cooling by internal air circulation, and cooling by introducing outside air. The purpose of this invention is to provide an air conditioner for commercial use.

゛The present invention will be described below with reference to embodiments shown in the drawings.

In the figure, reference numeral 1 denotes an inside air inlet, which is attached to the upper part of the rear package tray section or the vicinity thereof. Reference numeral 2 denotes an air outlet into the vehicle interior 10, and 3 represents an air outlet and outside air introduction port to the exterior of the vehicle, which may be installed at any position in the vehicle as long as it is outside the vehicle interior. 4 is a proar for blowing air, 5 is an evaporator for cooling the air, and 6 is a duct that serves both for introducing outside air and discharging hot air, and is connected to the air introduction part 11 and the discharge M, 12 of the proar 4. Reference numeral 7 denotes an inside air side duct that guides cold air into the vehicle interior 10, and an evaporator 5 is installed inside. Reference numeral 8 denotes a left circular outside air switching damper provided in the air introduction part 11 of the proa 4, and the damper 8 closes the outside air introduction duct 6 at the position 8' to bring it into the inside air introduction state. When the mirror is closed, outside air can be brought in. Reference numeral 9 denotes another internal/external air switching damper provided in the discharge part 12 of the proar 4, and is located at a position 9' where the external air introduction duct 6 is closed and the air sent from the proa 4 is guided into the vehicle interior after passing through the evaporator 5. The operation will be explained in the above configuration in which the duct is selectively switched to the illustrated state in which the duct is closed or the duct on the single room 10 side is closed and the duct is guided out of the vehicle. When the inside/outside air switching damper 8 (hereinafter referred to as the introduction part damper 8) in the air introduction part 11 of the proar 4 is in the position where either the inside air introduction port 1 or the outside air introduction duct 6 is closed, the discharge part 12 of the proa 4 The inside/outside air switching damper 9 (hereinafter referred to as the discharge part damper 9) can be switched to the closed position from either the outside air introduction duct 6 side or the inside air duct T side, so the explanation will be based on the combination of opening and closing. Kjru.

The introduction part damper 8 closes the inside air introduction port 1, and the discharge part damper 9 closes the inside air introduction port 1.
When the outside air introduction duct 6 side is closed, the outside air introduced from the outside air introduction port 3 passes through the outside air introduction duct 6, and the proa 4
The air then passes through the evaporator 5, is cooled, passes through the inside air duct (7), and is blown out from the air outlet 2 into the passenger compartment 10, thereby cooling the rear seats by introducing outside air.

The introduction damper 8 closes the outside air introduction duct 6 side.

When the discharge part damper 9 closes the outside air introduction duct 6 side, the air from the air introduction port 1 in the vehicle interior 10 flows into the proa 4.
After passing through the evaporator 5 and being cooled, the air is blown out as cool air through the air outlet 2 into the vehicle interior 10 through the air supply duct 7, and the rear seats can be cooled by internal air circulation.

Furthermore, the introduction damper 8 closes the outside air introduction duct 6 side,
When the discharge part damper 9 closes the inside air side duct 7, the air from the air inlet 1 in the single room 10 passes through the proa 4, passes through the outside air inlet duct 6 which also serves as a hot air exhaust, and then flows into the air outlet 3 to the outside of the vehicle interior. discharged from.

The hot air in the vehicle interior 10 can be quickly discharged. Note that each of the internal/external air switching dampers 8.9 in the above embodiment may be a rotary damper that can perform these functions simultaneously. Also.

An air purifying device may be installed in the middle of the air flow path to purify the air during cooling by internal air circulation.

Furthermore, even if the inside/outside air switching damper 8 in the air introduction part 11 of the proa 4 is identified with the outside air introduction duct 6 closed, it can be used in two ways: cooling by internal air circulation or hot air exhaust. good.

As described above, in the present invention, an inside/outside air switching damper is provided at the air introduction part and the discharge part of the proar in the automobile air conditioner, and an evaporator is placed in the inside air 111/vent connected to the discharge part.

It has the excellent effect that one device can be used for the 3S types of cooling by circulating inside air in the vehicle interior, cooling by introducing outside air, and discharging hot air from the vehicle interior.
