Description

[Detailed description of the invention] [Industrial application field] The present invention is a push-button type automobile equipped with an automatic button that automatically switches the mode of the direction of air-conditioned airflow and the rotation speed of the fan by button operation. The present invention relates to a heater control device.

[Prior Art] The conventional push-button type automobile heater control device described above is constructed as shown in FIG.

That is, as shown in the figure, the operation panel is separated into a mode operation panel 10A and a fan operation panel 10B, which are attached to the front of the driver's seat, and the mode operation panel 10A has a mode switching button 1.
2A and an automatic mode button 14A are provided, and the fan operation panel 10B is provided with a fan switching button 16B and an automatic fan button 18B.

Then, the driver can select and press either of the mode switching buttons 12A and the fan buttons 16B to perform air conditioning with the wind direction and air volume that suit his/her preference, and also change the air flow direction mode and air volume. If you want to automatically control the air conditioning, you just need to press both the automatic mode button 14A and the automatic fan button 18B, which are described above, and the air conditioning can be automatically controlled.

[Problems to be solved by the invention] Conventional problems By the way, in the conventional push-button type automatic heater control device described above, the automatic mode button 14A that automatically controls the mode and the rotation speed of the fan are automatically controlled. Since two automatic fan buttons 18B were installed, and both operation panels were separated and mounted at separate locations in front of the driver's seat, there were difficulties in operating the automatic buttons 14A and 18B in particular. .

In addition, since two automatic buttons are required, the respective automotive buttons 14A and 18B are mounted on both operation panels 10A and 10B.
However, in the limited space of the operation panels 10A and 10B, the automatic buttons 14A and 18B are small in size, making them difficult to operate.

Furthermore, as a result of the two automatic buttons being arranged, the total number of switch buttons including other switch buttons increases, resulting in a problem that it becomes difficult to identify the automatic button.

Purpose of the invention The present invention was devised in view of the conventional problems mentioned above, and its purpose is to use an automatic button to automatically control both the wind direction mode and air volume of an air-conditioned air flow. The objective is to improve the functionality and operability as well as improve the visibility of the buttons.

[Means and effects for solving the problem] In order to achieve this objective, the present invention is provided with a plurality of mode switching buttons that switch the wind direction mode of the air-conditioned air flow when any one of them is turned on. A mode operation panel attached to the front of the driver's seat, multiple fan switching buttons that switch the fan rotation speed when one of them is turned on, and one automatic button that turns off the fan switching button when turned on. In a push-button automobile heater control device that includes a fan operation panel that is arranged and attached to the front of the driver's seat and separated from the mode operation panel, a power supply path to a fan speed control circuit that automatically controls the rotation speed of the fan is provided. A fan-side connection stage that operates the fan speed control circuit by closing in conjunction with the operation of the automatic button, a switch that turns on in conjunction with the operation of the automatic button, and is self-excited and turned on when the switch is turned on. A mode side connecting means having a relay and a magnetic valve that operates when the relay is turned on and turns off all fan switching buttons, and a mode side connecting means that turns off the mode switching button and the fan switching button by operating the automatic button, and The present invention is characterized in that by operating a mode switching button or a fan switching button while an automatic control operation is being performed by operating a button, automatic control of only the rotational speed of the fan or the wind direction mode is performed.

With such a configuration, when the operator switches to automatic control of air conditioning, the mode of the wind direction and the amount of air blown can be automatically controlled at the same time by pressing the automatic button once.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which, as shown in the figure, a push-button heater control operation panel is provided separately in two parts, a mode operation panel 10A and a fan operation panel 10B, in front of the driver's seat. On the upper side of the mode operation panel 10A, there are a plurality of mode switching buttons 12 for switching the wind direction mode.
On the other hand, above the fan operation panel 10B, a plurality of fan switching buttons 16B for switching the rotational speed of the blower fan are arranged.

And an automatic button 36 that switches the wind direction mode and fan rotation speed to automatic control, which is a feature of the present invention.
is arranged on the fan operation panel 10B side. Although the automatic button 36 and the fan switching button 10B are omitted in the figure, they are connected by a first connecting means, such as a mechanical connecting mechanism such as a cam mechanism or a band plate, and the fan switching button 16B When one of the buttons 16B is pressed and the button 16B is fixed in the pressed position and the fan is rotating at the rotation speed displayed on the button, the automatic button 36 is pressed to switch the fan rotation speed to automatic. The fan switching button 16B, which is in the pushed-in state described above, is returned to its original position.

The automatic button 36 and the mode switching button 12A are the second
They are electrically connected by, for example, a magnetic valve 50 as shown in FIG. When the automatic button 36 is pressed, the pressed mode switching button 12A returns to its original state and is switched to automatic control of the wind direction mode. In this way, the automatic button 36
With a single operation, the fan rotation speed can be switched to automatic control at the same time as the wind direction mode.

Furthermore, if an operating indicator for the wind direction mode and the automatic control of the fan is provided in the automatic button, it can be visually confirmed whether both or either of the mode and the fan is being automatically controlled.

For example, FIG. 2 shows a circuit in which a photodiode is provided as an operating indicator in the automatic button of the device shown in FIG.

In the figure, when the automatic button 36 is pressed, all three interlocking switch contacts of the button switch 38 are closed, and the mode photodiode 40, fan photodiode 42, and fan speed control circuit 44 are supplied with power to turn the fan on. The rotation speed is automatically controlled.

Further, as shown in Fig. 3, a non-locking limit switch 46 is provided near the automatic button 36, which is a non-locking knob, and when the automatic button 36 is pressed, the button switch 38 is locked and the contact of the limit switch 46 is closed by the detection plate 36a, which activates the activation relay. 48, the magnetic valve 50 is operated to release the mode switching button 12A.

In this way, when both the mode and the blower fan are automatically controlled, both diodes 40 and 42 emit light, and when only one is automatically controlled, only the diode on the automatic side emits light.

[Effects of the invention] As explained above, according to the invention, both the direction mode and air flow rate of the conditioned airflow can be switched to automatic control at the same time with a single button operation, so the automatic button can be used. This has the effect of improving performance and operability, and since there is only one automatic button, the visibility of the button is improved.
