Description

[Detailed explanation of the invention] This invention was developed to improve ventilation in the cab of an automobile.
It relates to air conditioners used for heating, cooling, etc.

Generally, this type of air conditioner is equipped with a damper that opens and closes the cold air outlet of the casing, and the damper has a damper lever attached to the damper side and a control cable connected to the damper lever. It has been constructed so that it can be operated through.

It is desirable that such a damper be properly installed in its casing so that there is little air leakage from its cold air outlet in the event of blockage, but normally the damper control
When a cable or the like is incorporated into the casing, the damper is pressed against the cold air outlet side, and in this state, one end of the control cable is attached to the damper lever, so that the control cable's It is difficult to properly install the damper due to looseness or uneven installation, and therefore, when the damper is closed, air leaks from the gap between the damper and its cold air outlet. I was afraid.

In addition, in recent years, in order to prevent such air leakage, some dampers are configured with a spring attached near the rotation center of the damper to improve airtightness when the damper is closed. Since the damper is pressed against the cold air outlet side by its spring, a large operating force is required to open and close the damper, making it difficult to open and close smoothly. Ta.

The purpose and problem of this invention is to ensure that the damper that opens and closes the cold air outlet is attached to the casing in an appropriate state, prevents air leakage from the cold air outlet when the damper is closed, and that the damper opens and closes the damper. An object of the present invention is to provide an air conditioner for an automobile that can be operated smoothly.

In order to solve these problems, the air conditioner for an automobile of this invention includes a damper that is swingably supported in a casing at a predetermined position and that opens and closes an air outlet formed in the casing, and a damper that opens and closes the damper. a control cable consisting of an outer cable and an inner cable slidably held by the outer cable and having one end connected to the damper lever and the other end connected to the control lever. and a cable set for forcing the damper into a closed condition against the cold air outlet and preventing swinging of the damper lever in the return direction.
A pin is removably disposed in the outer wall of the casing at a predetermined location.

Hereinafter, preferred specific examples of the air conditioner for an automobile according to this invention will be described with reference to the drawings.

FIGS. 1 and 2 show a specific example 10 of the automobile air conditioner of this invention.

The air conditioner 10 is configured to be used for ventilation and heating in the cab of an automobile. A damper 13 that selectively opens and closes the air outlet 12 and the communication port 31, a damper lever 14 that opens and closes the damper 13, and a control cable that connects a control lever (not shown) to the damper lever 14. 15 and a cable set pin 16 which allows the control cable 15 to be set so as to maintain the damper 13 in a closed condition.

The casing 11 is injection molded in a split mold from hard synthetic resin so that it can be placed below an instrument panel (not shown) in the cab of an automobile. A cold air outlet 12 is formed at a position corresponding to the seat side, and warm air outlets 17, 18, and 19 are further formed at a lower position.

Of course, the casing 11 is provided with a blower chamber 29 and a heater chamber 30, which are connected to each other by a communication port 31, in which the blower, i.e. the Sirotsko fan 20, is also connected. In Chiamba 30,
Heater elements 21 are arranged respectively.

Since the Sirotsko fan 20 and the heater element 21 are constructed similarly to existing ones, a description of their construction will be omitted.

In the casing 11 configured in this way, a damper 13 is provided inside the cold air outlet 12.
is rotatably mounted.

The damper 13 is swingably supported in the casing 11 at a predetermined position, selectively opens and closes the cold air outlet 12 and the communication port 31 formed in the casing 11, and is made of hard plastic material. It is molded from resin, steel, etc. That is, the damper 13 is mounted on a pivot shaft 23 rotatably disposed in the casing 11 at a position below the cold air outlet 12 so as to selectively close the cold air outlet 12 and the communication port 31. It is fixedly mounted and is thus rotatably supported within its casing 11 by its pivot shaft 23.

Of course, the pivot shaft 23 is fixed to the lower part of the damper 13, and a damper lever 14 is attached to one end of the pivot shaft 23 outside the casing 11.

The damper lever 14 opens and closes the damper 13, and is rotatably connected to one end of the pivot shaft 23 extending outside the casing 11.

The control cable 15 connects one end to the damper lever 14 and also connects the control cable 15 to the instrument panel (not shown).
The other end is connected to a control lever (not shown) mounted on a panel (not shown), and the operating force from the control lever is transferred to the damper.
The signal can be transmitted to the lever 14.

Of course, this control cable 15 is a normal push-pull cable, and includes an outer cable 32 and an outer cable 32.
The outer cable 3 consists of an inner cable 33 that is slidably held by the outer cable 32 and has both ends extending outward from both ends of the outer cable 32.
2 has one end fixed to the outer wall of its casing 11 with a clip 28 and the other end (not shown) fixed to its control panel with a clip (not shown), while its inner cable 33 has one end The other end is connected to the damper lever 14, and the other end is connected to the control lever.

The cable set pin 16 sets the damper 1 when the inner cable 33 is pulled.
3 is used for setting the control cable 15 for maintaining the cold air outlet 12 in a closed state.
It is arranged on the outer wall of the casing 11, and when setting the control cable 15, presses the damper 13 into the closed state on the cold air outlet 12, and presses the damper lever 1 in the return direction.
4. Prevent the swing of the 4, and control it.
After the cable 15 is set, it is removed.

Further, in detail, the cable set pin 16 is located outside the casing 11,
Furthermore, the damper lever 14 is integrally molded on the outer wall of the casing 11 in the vicinity of the damper lever 14, and when the control cable 15 is set, the damper lever 14 in the return direction is
4, the damper 13 is
The control cable 15 is pressed into a closed state against the cold air outlet and is bent after the control cable 15 is set.

Therefore, the cable set pin 16 is
It is sufficient to have a diameter that can temporarily maintain the damper 13 in a closed state, and furthermore, the cable set pin 16 should have a diameter that can be easily broken at the base side of the cable set pin 16. It is also possible to reduce the diameter of the groove or to form a crease (not shown).

Next, a method for assembling the damper 13 and control cable 15 to the casing 11 in the air conditioner 10 configured as described above will be described.

First, the damper 13 is assembled to the casing 11 as described above, and the damper 13 is placed in such a manner as to close the cold air outlet 12, as shown in FIGS. 1 and 2. .

Of course, in such a condition, the damper lever 14 is hung on the cable set pin 16.

Furthermore, the damper lever 14 has a
Since the control cable 15 connects the other end of the inner cable 33 to the control lever, one end of the inner cable 33 is connected.

So that control cable 15
is the damper lever 14 and its control
If connected to the lever, the inner cable 3 that opens and closes the damper 13
Since the length of damper 3 is constant, the control cable 15 is set to put the damper 13 in the proper state.

That is, the control cable 15
is adjusted by the deflection of the outer cable 32. First, as shown in FIGS. 1 and 2, lift the damper lever 14 by hand and move the damper 13 to the cold air outlet 12. The outer cable 32 is pressed into a closed state, the amount of deflection of the outer cable 32 is adjusted, in other words, the amount of protrusion of the outer cable 32 from the clip 28 is adjusted, and the screw is tightened, and the clip 28 is pressed to a closed state. The outer cable 32 is connected to the casing 11.
be fixed to the outside wall of the

Thus, once the control cable 15 is set, the cable set pin 16 is broken off.

Therefore, if the cable set pin 16 is broken, the damper 13 will be moved to its control position by operating the control lever described above.
The control cable 15 is opened and closed via the cable 15, but since the control cable 15 is connected to the damper lever 14 based on the closed state of the damper 13, the control lever is positioned on the heating side. If so, the cold air outlet 12 is
The damper 13 ensures a tight seal and prevents air leakage.

Of course, in the connection work of the control cable 15 as described above, the damper lever 1
4 is placed in a state where its rotation is prevented by its cable set pin 16, so that the connection work is facilitated.

FIG. 3 shows another specific example 24 of the air conditioner for an automobile according to this invention.

That is, the cable set pin 16 in the above-described specific example 10 was described as being formed integrally with the casing 11 and folded after the control cable 15 is connected to the damper lever 14. The cable set pin 25 in Example 24 is molded separately from the casing 11 and is configured to be inserted into the outer wall of the casing 11.

In other words, in the above-described specific example 10, a built-up portion 26 having a pin hole 27 is formed on the outer wall of the casing 11 corresponding to the position where the cable set pin 16 is provided, and the pin hole A cable set pin 25 molded from synthetic resin, metal, etc. is inserted into 27.

In the specific example 24, except for the cable set pin 25 and its support structure, the structure is the same as that of the above-mentioned specific example 10, so the same reference numerals will be given to those structures and the explanation will be omitted. .
Of course, in the specific example 24, the method of assembling the control cable 15 to the casing 11 is almost the same as in the case of the above-mentioned specific example 10, but the cable set pin 25 is attached to the control cable 15. Damper lever 14
It is removed after being connected to.

According to this invention, the damper is placed in advance on the outer wall of the casing at a predetermined position, and when the control cable is set, the damper is pressed into the closed state against the cold air outlet, and the damper lever is oscillated in the return direction. A cable set pin is provided which prevents the control cable from moving and is removed after setting the control cable so that the damper that opens and closes the cold air outlet is properly attached to the casing and the damper is removed. When the damper is closed, air leakage from the cold air outlet is prevented, the damper can be opened and closed smoothly, and the control cable can be set very easily.
