Description

Automotive air conditioning unit with auxiliary fan

The present invention relates to a vehicle air conditioner having an auxiliary fan, and in particular, by providing an auxiliary fan in an appropriate portion of the dashboard so that occupants in a vehicle can create a comfortable indoor environment, a conventional air conditioning system is provided to a user. The present invention relates to a vehicle air conditioner having an auxiliary fan for eliminating various inconveniences.

In general, the car air conditioner provides a comfortable environment for the passengers in the weather and driving conditions, and also prevents frost on the windshield, thus protecting the driver's watch and driving safely.

The air conditioner is largely classified into a device for heating or cooling. When heating, a heat source that generates heat from the power generating unit of the vehicle body is used, and when cooling, a separate cooling cycle is used to blow the indoor unit by the blowing means. Forced convection cycles to ensure coordination. At this time, the air conditioning control device is selected, and the airflow amount of the air conditioning air is appropriately selected, and as shown in the accompanying drawings, as illustrated in FIG. 1, various directions in the vehicle, a defroster duct (a), and a ventilation duct ( distribution and supply to the ventilation duct (b) and the floor duct (c).

The air conditioner generally has a blower fan, an evaporator, and a heater core, and has a blower guide for guiding air conditioning air in various directions in the room, and at a suitable place for the blower guide. One or more dampers for controlling the direction change or direction are selected, and the dampers are opened and closed by an air conditioning control device installed in the vehicle inner shaft, and the flow path direction switching or the blowing direction of the air conditioning air is selected.

Such an air conditioning control device has one or more control levers that apply an opening and closing force to each of the dampers, and has an adjustment knob exposed to the front end of each control lever, that is, the front plate of the control device. It has a control lever which is installed to be freely rotatable with one point as the center of rotation, and it is equipped with a control knob at the front end of the control lever and adopts a configuration to open and close the damper by holding the control knob and moving it left and right. .

FIG. 2 is a sectional view of a conventional vehicle cooling and heating apparatus, which automatically adjusts the air blowing means 3 installed after the internal and external air introduction dampers 2, and then the evaporation means 4 and the temperature inside the vehicle. First switching damper (6) for mixing air, second and third switching dampers (7) (8) and heating core (5) for distributing heated or cooled airflow to various locations within the vehicle. It consists of one module body 1.

The cold and hot air supply module according to the related art is configured to flow cold air from the air conditioner into the floor duct, i.e., the lower part of the driver's or passenger's body. There was no choice but to feel uncomfortable in the driving environment of the car.

Accordingly, even when the air conditioner was operated, it was necessary to wait for a certain time from the outside of the vehicle until complete air circulation was achieved, and in order to adapt to the changed temperature while the driver or the passenger was sitting on the seat, the discharged cold wind was uniform in the interior of the vehicle. Since it had to be cycled, it is difficult to expect a satisfactory effect in a short time.

The present invention has been made to solve the above problems, the purpose is to provide an auxiliary fan in the appropriate portion of the dashboard so that occupants in the vehicle interior can create a comfortable indoor environment, It is to provide a more improved air conditioning efficiency system by solving the problem that the proper air flow to the position of the rear seat occupant because it is located under the body of the occupant.

The purpose of the present invention is to provide an internal and external air introduction damper for rotating and opening and separating the internal and external air at the inlet, a blowing means for supplying the introduced air at a constant pressure, and an evaporation means for heat exchange while being circulated from a separate refrigerant circulation device; An air conditioning duct is separately provided on one side of the defroster duct inlet formed on the upper end of the third switching damper, and an automobile cold and hot water supply module including a heater core heated by a separate heat transfer device, a plurality of switching dampers, and a third switching damper. Is achieved by extending the inside of the auxiliary fan.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

3 is a cross-sectional view of a vehicle cooling and heating device according to the present invention. According to the present invention, the present invention is largely composed of an internal and external air introduction damper (2), an evaporation means (4) in which heat exchange is performed while being circulated from a separate refrigerant circulation device, and a plurality of switching dampers (6) (7) (8). The air-conditioning duct 9 is separately provided at one side of the inlet and outlet of the cold and hot air supply module and the defroster duct a formed at the upper end of the third switching damper 8 to extend into the auxiliary fan 10. Is done.

Specifically, as shown in FIGS. 3 and 4, the internal and external air introduction dampers 2 which rotate and open and separate the internal and external air at the inlet, and the blowing means 3 for supplying the introduced air at a constant pressure, are separately provided. Car cooling consisting of evaporation means (4) for circulating heat from a refrigerant circulation system of a refrigerant, a heater core (5) heated by a separate heat transfer device, and a plurality of switching dampers (6) (7) (8). The air-conditioning duct 9 is separately provided at one side of the inlet of the warmer supply module and the defroster duct a formed at the upper end of the third switching damper 8.

The present invention configured as described above has an auxiliary fan at an appropriate portion of the dashboard so that a passenger in a vehicle can provide a comfortable indoor environment, and the rear seat is located in the existing air conditioner because the air conditioner is located under the passenger's body. It is possible to solve the problem that the proper air flow to the passenger's position is not ensured, thereby providing a more improved air conditioning efficiency system.

In addition, in order to maintain the same air-conditioning efficiency of the present invention, it is possible to reduce the cost of installing a plurality of air-conditioning ducts in a double or triple in the past, adding the same pleasant indoor environment in consideration of the economics in terms of consumers and automobile production sites. I can do it.
