Abstract

PURPOSE:To facilitate the use of side air outlets for defrosters in an air blowing structure for a ventilator of an automobile, by arranging independently, to a duct, air passages that are led to a center and side air outlets, and allowing their on-off doors to be operated at the driver's seat. CONSTITUTION:A driver rotates manually a control lever 28 to close the door 23 and open the door 24 through cables respectively. As a result, the air heated by a heater unit 1 is flowed from a junction 22 via the door 24 into the air passage 21, and is blown from the side ventilator air outlets 4, 5. In this case, they can serve as side defrosters by suitably directed and controlled a louver 33. Similarly by opening the door 26, the front defroster air outlet can be used. When the door 26 is closed, and the doors 23, 24 are opened, they can serve as ventilators. Thus the side air outlets can be readily used as side defrosters.

Description

[Detailed Description of the Invention] This ridge is an air blowing structure of an air conditioner for an automobile.
This article relates to an air blowing structure for an I# venterator.

Examples of air blowing structures of conventional air conditioners include those shown in FIG. 111 and jlI2Ia. That is, a ventilator data 2 is connected to the heater unit 1, and air is guided through the ventilator data 2 to the center inilator outlet 6 and the left and right side ventilator outlets 4 and 5. There is. The center ventilator outlet 3 is approximately in the center IIK of the instrument none, and the left and right ventilator outlets 4, 5
are located on the left and right sides of the instrument panel 6, respectively, and each air outlet! , 4.5Kjl attached shutter 7.8,911
By doing 111, the above-mentioned air outlet can be used as an instrumental air outlet! +, 4. Air is blown out from S toward the room as shown by arrows M, B, and C. In addition, in the figure, there is a defroster outlet from 10 companies, which is also placed on the upper surface of the instrument panel 6 and blows air toward the heater unit 1 and the windshield 11. is a fan connected to the heater unit 1 and installed in the intake box 1! 6!, which is schematically shown in the middle.

However, in the air blowing structure of such a conventional air conditioner, the center ventilator outlet 6 and the left and right side ventilator outlets 4 and 5 must be attached to each outlet in order to close them separately. A certain shutter7.
8.9t - Because it has a structure that can be opened and closed manually, it can be used to prevent fogging on the side windows of automobiles and other Q uses.The side inverter outlet has a 4.5t opening, so to speak, as a nide defrost! If you want to use it as an air outlet, close the shutters of the side ventilator air outlets 4 and 5 so that hot air is blown out from the side ventilator air outlets 4 and 5, and warm air is not blown out from the center air outlet 3. 8 and 9 to "open" and the shutter 7tr of the center inilator outlet 3 to be closed. Exit! , 4.5 or any shutter 7.8.9trlllJ, which makes the operation complicated, and especially when the front seat occupant is the driver, the assist side shutter 8 is not the driver's seat. Due to the distance it is driving Kr1l
It is dangerous to operate the "i.close" operation, and there is a problem in that it is difficult to use the side ventilator outlets 4 and 5 as side defroster outlets.

This invention was made by focusing on the air blowing structure of such conventional air conditioners, and it is possible to blow air from the center intilator outlet and the nide ventilator outlet independently by hand operation. By doing so, it is intended to solve the problems of the conventional system.

Hereinafter, this invention will be explained in detail based on stgiii,
(For convenience of explanation, parts similar to those in the conventional model will be designated by the same reference numerals and repeated explanations will be omitted.) jlms-5llI is a diagram showing an embodiment of the present invention. . First, the configuration will be explained. The ventilator duct 2 is a ventilation passage 2 leading to the center ventilator outlet 3.
0 and left and right side ventilator outlets 4 and 5 iIJ&
A ventilation passage 21 is provided independently. 22 is open air passage 2
This is the branch point between 0.21 and heater enit 1. Opening/closing doors 25, 24 are provided on the population side of the ventilation passages 20, 2, 140 facing this branch 1122, respectively. And also the above branch 1122. A percent opening/closing door 26 is provided on the entrance side of the defroster passage 25 facing the air.

It should be noted that it is free to decide how to form the open air passages 20, 21 inside the ventilator duct 2. In the example shown in FIG. The ducts 2m and 2b are connected to the ducts 2a and 1k, and the inside of the ducts 2a and 2b is used as a ventilation passage 20.21. [See Figure 5] The opening/closing doors 2M, 24, and 26 can be operated by the driver at hand.In the illustrated example, the driver of the instrument/channel 6 can easily operate the control 27 located at the 11th position. The control lever 28.
29 are respectively connected to opening/closing doors 23 and 24 by cables.

- Middle door 26t - Round control lever and cable that can be opened and closed by hand operation are omitted.

Reference numerals Mo and 31 denote grills, which are respectively equipped with loupes 32 and 5M and are attached to the center ventilator outlet 3 and the left and right side ventilator outlets 4.5.

Next, the action will be explained.

When using the nide ventilator outlets 4 and 5 as a nide defroster, the driver manually rotates the control lever 28 and closes the door 23 through the cape k.
The door 24 is left in the "open" position until t. The air blown by the fan 12 passes through the heater unit 1 to the salmon smelter s22, passes through the 241 doors in the "-" state, flows into the ventilation passage 21, and flows into the left and right side insulator air outlets 4.
, 5. At this time, the louver 63 is manually operated in advance to align the wind axes in an appropriate direction of the side window glass (II not shown). If the front defroster outlet 10 is also used, the %
All you have to do is allow it to flow in.

When using it as the original intilator, the driver manually operates the door 2 ink via the control levers 28, 29 and each cable.

By setting the door 24 in the ``open'' state and the door 26 in the ``closed'' state, the air f-
B:/The air is to be blown out from the tin infiltrator outlet 3 and the left and right side ventilator outlets 4 and 5.

When used as a front differential zero star (doors 2M and 24tr are closed by hand operation via the control levers 28 and 29 and each cable), while the door 26 is opened.
In this state, all the air from the heater unit 1 passes through the defoster passage 25 and is blown out from the 70-point defroster outlet 10.

As explained above, according to the present invention, the configuration is such that the ventilator duct is independently provided with ventilation passages leading to the Y-chillator outlet on both the center and side sides, and a driver is provided on the inlet side of these ventilation passages. The air from the heater unit is guided through the air passages mentioned above to both the center and side inverter outlets, and each opening/closing door can be opened by hand. Or, by setting it to "closed", the side inverter outlet can be easily used for the side defmister, and the driver can operate the opening/closing door manually, making it safer to operate while driving. The door that can be opened and closed to distribute the air from the head unit is independent. 31 is installed on the entrance side of each ventilation passage, so there is an effect that pressure rise in the ventilation passages of each building is small and air can be blown out efficiently and freshly.
