Description

  The present invention relates to an air conditioning system.

  There exists an air-conditioner for vehicles, such as patent documents 1. Some of such air conditioners for vehicles are provided with a switch for adjusting temperature and air volume integrally with the air outlet.

JP 2005-280669 A

  If a switch is provided in the center of the air outlet or in the vicinity of the air outlet, the air that is drawn from the air outlet is applied to the hand that is trying to operate the switch. Depending on the temperature and the air volume of the conditioned air, the switch operator may feel uncomfortable due to the conditioned air hitting the hand.

  An object of the present invention is to provide an air conditioning system that is less likely to cause discomfort.

  In order to solve the above-described problem, an air conditioning system having a blower-integrated switch includes a detection unit that detects the proximity of an object to the switch, and the detection unit that detects the proximity of the object to the switch. And a control unit that adjusts the conditioned air blown from the outlet to be weakened or not hit against the object as compared to before the proximity of the object is detected.

According to this system, since the conditioned air hitting the hand operating the switch is weak or the conditioned air itself does not hit the hand, the operator of the switch is less likely to get discomfort due to the conditioned air.
In the above system, when the proximity of an object is detected to the switch through the detection unit, the control unit reduces or reduces the air volume of the conditioned air compared to before the proximity of the object is detected. It is preferable.

  According to this system, since the air volume of the blown air decreases or becomes zero, the air conditioning wind hitting the hand operating the switch is weak or the air conditioning air itself does not hit the hand. Difficult to get uncomfortable due to wind.

  In the above system, when the proximity of the object to the switch is detected through the detection unit, the control unit is configured to move the conditioned air in a direction away from the object compared to before the proximity of the object is detected. It is preferable to adjust the wind direction.

  According to this system, the direction of the conditioned air is adjusted so as to be away from the hand operating the switch. For this reason, since the conditioned air hitting the hand operating the switch is weakened or the conditioned air itself does not hit the hand, the switch operator is less likely to get uncomfortable feeling due to the conditioned air.

  In the system, it is preferable that the control unit determines a direction in which the object approaches through the detection unit, and adjusts the direction of the conditioned air so as to avoid the direction in which the object approaches.

  According to this system, it becomes difficult for the air conditioned air to hit the hand operating the switch or the air conditioned air itself does not hit the hand, so that the operator of the switch is less likely to get discomfort due to the air conditioned air.

  The air conditioning system of the present invention has an effect that it is difficult to obtain an uncomfortable feeling due to the conditioned air.

(A) is a front view of the outlet, (b) is a front view of the outlet without the switch, and (c) is a front view of the outlet with the switch and the left-right control plate omitted. (A) is a front view of the outlet when the hand approaches, (b) is a front view of the outlet immediately after the hand approaches.

Hereinafter, an embodiment of an air conditioning system mounted on a vehicle will be described with reference to the drawings.
As shown in FIG. 1, the air conditioning system 1 includes an air conditioning control unit 2, a blowout port 3, an electrostatic sensor 4, a switch 5, a wind direction control plate 6, a heat exchanger 7, and a fan 8. The electrostatic sensor 4, the switch 5, and the heat exchanger 7 are electrically connected to the air conditioning control unit 2. The wind direction control plate 6 is connected to the air conditioning control unit 2 via the wind direction control motor 11, and the fan 8 is connected to the air conditioning control unit 2 via the fan control motor 12.

The blowout port 3 is a part that blows out the conditioned air into the passenger compartment. As shown in FIG. 2 (a), the air outlet 3 has a cylindrical shape.
The electrostatic sensor 4 detects the proximity of a conductor such as a hand. As shown in FIG. 2A, the electrostatic sensor 4 is arranged in an annular shape at the tip of the outlet 3.

  The switch 5 is operated when changing air-conditioning settings, for example, modes such as temperature and outlet selection. As shown in FIG. 2A, the switch 5 is located at the center of the tip of the outlet 3. Note that the switch 5 may also serve as a display unit for a function that is changed by an operation.

  The air direction control plate 6 is a plate that adjusts the direction of the conditioned air blown from the air outlet 3. As shown in FIGS. 2B and 2C, the air direction control plate 6 is located inside the outlet 3, that is, behind the switch 5. The wind direction control plate 6 includes a vertical direction adjustment control plate 6a for adjusting the vertical direction of the conditioned air and a horizontal direction adjustment control plate 6b for adjusting the horizontal direction of the conditioned air. It is a generic name. The wind direction control plate 6 is tilted by the driving of the wind direction control motor 11 and adjusts the direction of the conditioned air. The wind direction control motor 11 includes a vertical adjustment motor (not shown) for adjusting the inclination of the vertical adjustment control plate 6a and a horizontal direction for adjusting the inclination of the horizontal adjustment control plate 6b. It is a general term for an adjustment motor (not shown).

The wind direction control plate 6 is physically connected to an adjustment knob (not shown). For this reason, the inclination of the wind direction control plate 6 can be adjusted manually by operating the adjustment knob.
The heat exchanger 7 takes in outside air and inside air and exchanges heat.

  The fan 8 rotates when the fan control motor 12 is driven, and sends the air heat-exchanged in the heat exchanger 7 to the outlet 3. Depending on the rotational speed of the fan 8, that is, the driving state of the fan control motor 12, the strength of the conditioned air blown from the air outlet 3 is switched.

The air conditioning control unit 2 controls the heat exchanger 7 and the fan control motor 12 based on the air conditioning setting input through the operation of the switch 5.
In addition, the air conditioning control unit 2 controls the wind direction control motor 11 and the fan control motor 12 through detection of the proximity of the conductor in the electrostatic sensor 4. More specifically, when the electrostatic sensor 4 detects the proximity of the conductor in the electrostatic sensor 4, the air conditioning control unit 2 drives the wind direction control motor 11 so that the conditioned air is blown out in a direction avoiding the conductor. Adjust the tilt. Further, the air conditioning control unit 2 reduces the rotational speed of the fan 8 by weakening the drive of the fan control motor 12.

Next, the operation and effect of the air conditioning system 1 will be described. It is assumed that the conditioned air is blown out from the entire outlet 3 as indicated by dots in FIG.
As shown in FIG. 3A, when the hand (conductor) that is to operate the switch 5 approaches from below the outlet 3, this is detected by the electrostatic sensor 4. When the air-conditioning control unit 2 detects the proximity of the hand from the lower side of the air outlet 3 through the electrostatic sensor 4, the air-conditioning control unit 2 drives the wind direction control motor 11 (vertical direction adjustment motor) to control the vertical direction adjustment control plate 6a. Tilt upwards. Therefore, as indicated by dots in FIG. 3B, the conditioned air is blown upward from the upper half of the blowout port 3. Thereby, the conditioned air hitting the hand approaching the switch 5 from the lower side of the outlet 3 is weak, or the conditioned air itself does not hit the hand. For this reason, even if the temperature of the conditioned air is high or low, it is difficult for the operator of the switch 5 to get uncomfortable feeling.

  In addition, when the air conditioning control unit 2 detects the proximity of the hand to the air outlet 3 through the electrostatic sensor 4, the driving of the fan control motor 12 is weakened to reduce the rotational speed of the fan 8. Therefore, the amount of conditioned air blown out from the air outlet 3 is reduced as compared to before the hand approaches the air outlet 3. Thereby, the air-conditioning wind which hits the hand which approaches the blower outlet 3 becomes weak. For this reason, even if the temperature of the conditioned air is high or low, it is difficult for the operator of the switch 5 to get uncomfortable feeling.

In addition, you may change the said embodiment as follows.
In the above embodiment, when the air conditioning control unit 2 detects the proximity of the hand (conductor) to the outlet 3 through the electrostatic sensor 4, it drives the wind direction control motor 11 to tilt the wind direction control plate 6. The drive speed of the fan control motor 12 is weakened and the rotational speed of the fan 8 is reduced, but either one of them may be executed. Even in such a configuration, the air-conditioning wind hitting the hand is weak or the air-conditioning air itself does not hit the hand, so that the operator of the switch 5 hardly gets uncomfortable feeling.

  In the above embodiment, the proximity of the hand (conductor) to the outlet 3 is detected by the electrostatic sensor 4, but the proximity to the outlet 3 is detected by another method, for example, an infrared sensor or a camera image. It may be. Further, the detection target is not limited to a conductor, but may be an object.

  In addition, the air conditioning control unit 2 determines the direction in which an object approaches from the detection results of a plurality of proximity sensors, for example, and the direction of the conditioned air through drive control of the wind direction control motor 11 so as to avoid the direction in which the object approaches May be adjusted.

  For example, as shown in FIGS. 3A and 3B, when a hand (object) approaching the air outlet 3 approaches from the lower right side of the air outlet 3, the conditioned air is lower right. The air conditioning control unit 2 performs drive control of the wind direction control motor 11 so as to avoid the above, that is, so as to go upward. Even if comprised in this way, since the air-conditioning wind which hits the hand which operates a switch is weak, or the air-conditioning wind itself does not hit a hand, the operator of a switch does not get the discomfort by an air-conditioning wind easily.

  Note that the detection of the direction in which an object approaches is not limited to the detection result of a plurality of proximity sensors. If the detection unit alone can detect the direction in which the object approaches, the air conditioning control unit 2 does not have to calculate the direction in which the object approaches.

  In the above embodiment, the vertical and horizontal directions of the conditioned air blown from the outlet 3 can be adjusted by the vertical adjustment control plate 6a and the horizontal adjustment control plate 6b. The configuration may be such that only one can be adjusted.

In the above embodiment, the airflow direction of the conditioned air blown from the blowout port 3 is changed by the wind direction control plate 6, but the blowout port 3 itself may be tilted.
In the above embodiment, the amount of the conditioned air blown from the blowout port 3 is adjusted by controlling the rotational speed of the fan 8 by the drive control of the fan control motor 12, but may be adjusted as follows. That is, when the proximity of a hand (conductor) to a specific air outlet 3 among a plurality of air outlets 3 is detected, supply of conditioned air to the specific air outlet 3 is performed by a blocking wall (not shown) or the like. Cut off. That is, the air volume of the conditioned air is set to zero. With this configuration, since the conditioned air is not blown out from the blow-out port 3 that is close to the hand, the conditioned air is not applied to the hand, so that the switch 5 can be operated even if the temperature of the conditioned air is high or low. The person is less likely to get discomfort. The air conditioning control unit 2 may stop driving the fan control motor 12, that is, stop the rotation of the fan 8, so that the airflow of the conditioned air becomes zero. In addition, here, the supply of the conditioned air to the specific air outlet 3 is cut off, but the interruption is an example, and the amount of the air conditioned air blown from the air outlet 3 may be reduced.
