The above-mentioned air conditioner is disclosed in, for example, Patent Document 1. Specifically, the air conditioner of Patent Document 1 is equipped with an image sensor for capturing image information of an indoor space, an upper and a lower flap for detecting the motion by the acquired image information, and controlling the air direction in the vertical direction of the indoor unit The left and right flaps for controlling the wind direction in the left and right directions can be distributed as a flap mechanism for freely controlling the airflow regardless of the position of a person, And controls the direction and distance in which the air is blown toward the region where the air exists.

As described above, by mounting the image pickup element and the temperature sensor, it becomes easy to grasp the indoor situation and to detect the person, and it has become possible to perform fine air conditioning management. However, as described in Patent Document 2, an infrared sensor used for temperature detection generally has a slower response speed than an imaging device such as a CCD. For this reason, there may be a deviation between the actual temperature of the predetermined position of the sensed image detected by the image sensing element and the temperature detected by the temperature sensor such as an infrared sensor.

Further, the infrared sensor used for temperature detection does not have a two-dimensional high resolution such as an image pickup device such as a CCD. Therefore, since the one-dimensional sensor is scanned and used, temperature detection is performed a plurality of times, and it takes time to scan the detection area. Therefore, there is a problem that the temperature at a predetermined position can not be accurately obtained.

It is also possible to provide an image pickup device capable of grasping a state in which a time change is short such as detection of a person entering or leaving an activity and a time change such as an arrangement of a room or optimization of an air- A method of controlling the temperature sensor is required.

An object of the present invention is to provide an air conditioner equipped with a detection device in which an image pickup element and a temperature sensor are operated in a linkage manner to reduce the influence of the response speed of the temperature detection sensor.

In order to solve the above problems, an air conditioner according to the present invention comprises: an image pickup unit which rotates in the left-right direction to pick up an image of a room; a temperature detection unit which rotates in the left- And a sensor driver for starting the rotation of the imaging unit when the detection area of the detection unit partially overlaps.

According to another aspect of the present invention, there is provided an air conditioner comprising: an image pickup unit that rotates about one direction of an image pickup element disposed two-dimensionally and captures an indoor air-conditioned room; And a temperature detection unit for detecting the radiation heat in the room, wherein the image pickup unit and the temperature detection unit perform image pickup and temperature detection in substantially the same range, and the image pickup unit and the temperature detection unit A first operation state in which the rotation in one direction is operated in parallel and a second operation state in which the rotation operation in the imaging section and the rotation operation in one direction of the temperature detection section are performed in order.

The air conditioner to which the present invention is applied can reduce the adverse effect due to the response speed of the temperature detecting sensor, thereby improving the comfort of the occupant and increasing the energy saving effect.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings and the embodiments, the same or similar components are denoted by the same reference numerals, and redundant description is omitted.

1 is a front view showing an appearance of an air conditioner according to the present embodiment. The indoor unit 1 and the outdoor unit 2 are connected to each other by a refrigerant pipe (not shown), and the indoor unit 1 and the outdoor unit 2 are connected to each other by a well- The room in which the indoor unit (1) is installed is air-conditioned by the refrigerant cycle. The indoor unit 1 and the outdoor unit 2 are configured to transmit and receive information to each other through a communication cable (not shown).

The remote control 3 is operated by the user and transmits an infrared signal corresponding to the operation instruction of the user to the remote control 3 receiving unit of the indoor unit 1. The content of the signal is a command such as an operation request, a change of a set temperature, a change of a timer, an operation mode, and a stop request. The air conditioner performs the air conditioning operation such as the cooling mode, the heating mode, and the dehumidification mode on the basis of these signals.

Further, on the front face of the indoor unit 1 of the air conditioner, an image pickup means 26 and a temperature detection means 27, which will be described in detail later, are provided.

In the indoor unit, there are a room temperature sensor for measuring the temperature of air taken in the indoor unit 1, a humidity sensor, and a sensor unit 4 comprising an illuminance sensor. Similarly, the outdoor unit 2 is also provided with an outdoor temperature sensor.

Reference numeral 11 denotes an electrical component, which constitutes a control section 7 for controlling the air conditioner 1 in question. Details will be described with reference to Fig.

2 is a side sectional view of the indoor unit 1. Fig. The housing base 8 includes a heat exchanger 9, a blowing fan 10, an electrical component 11 (see Fig. 1), a sensor portion 4 (see Fig. 1), an image pickup means 26, 27) and the like.

The heat exchanger 9 has a plurality of heat transfer tubes and is configured to heat the air taken in the indoor unit 1 by the blowing fan 10 with a refrigerant flowing through the heat transfer tubes to heat or cool the air. On the other hand, the heat transfer pipe communicates with the above-described refrigerant pipe (not shown) and constitutes a part of a known refrigerant cycle (not shown).

The left and right air side airfoil plates 13 are driven by a motor for the left and right air side airfoil plates 13 (not shown) with a pivot shaft (not shown) provided at a lower portion thereof as a fulcrum in accordance with an instruction from the control unit 7 Omitted).

The upper and lower wind deflector plates 14 are provided on the upper and lower wind deflector plates 14 with the pivot shafts (not shown) provided at both ends thereof as a point in accordance with an instruction from the control unit 7 And is rotated by a motor (not shown).

The front panel 15 is provided so as to cover the front face of the indoor unit 1 and is configured to be rotatable by a motor (not shown) for the front panel 15 with the lower end as an axis. Incidentally, the front panel 15 may be configured to be fixed to the upper end, or may not be pivotable.

The air blowing fan 10 shown in Fig. 2 rotates to blow room air from the front surface of the indoor unit 1 through the air inlet port 17 and the filter 16, and the air exchanged by the heat exchanger 9 Is guided to the take-out air passage (18). The air guided to the takeout air passage 18 is adjusted by the left and right air side airfoil plate 13 and the upper and lower airfoil plate 14 so as to be directed to the outside from the air blow-out port 19 to ventilate the room.

That is, the blowing air amount is controlled by the rotational speed of the blowing fan 10, the right and left blowing directions are suppressed by the rotation of the left and right air side plates 13, and the upward and downward blowing directions Respectively.

The image pickup means 26 is, for example, a CCD (Charge Coupled Device) image sensor 26b (see FIG. 3B) and is provided at the lower portion of the center of the front panel 15 in the left and right direction. In addition to this, an infrared sensor may be used.

The temperature detection means 27 is a thermopile 27b (see Fig. 3A) composed of, for example, lateral × paper 1 × 1 pixels, 4 × 4 pixels and 1 × 8 pixels, In the left and right direction. In the present embodiment, the case of using the thermopile 27b composed of 1 x 8 pixels will be described. In addition to this, thermography may be used.

The imaging means 26 and the temperature detecting means 27 are provided so that the optical axis 36 of the lens is directed downward by a predetermined angle with respect to the horizontal line 37 and the room in which the indoor unit 1 is installed is appropriately So that it can be picked up. The angle at which the imaging means 26 faces downward is substantially the same as the angle at which the temperature detecting means 27 faces downward.

When the detection range of the image pickup means 26 and the temperature detection means 27 in the vertical direction is different, the upper end of the detection range is matched. Alternatively, the lower end may be aligned.

The imaging angle of the imaging means 26 and the temperature detection means 27 in the horizontal direction is substantially the same. Alternatively, one of them may be larger than the other, and a substantially equivalent angle of view may be obtained by changing the angle of view by turning. The image pickup means 26 and the temperature detection means 27 are provided so as to be positioned horizontally or vertically to each other.

It is preferable that the image pickup means 26 and the temperature detection means 27 are provided close to a position where detection of a space such as a front center portion or an upper front portion of the indoor unit 1 is possible. This makes it possible to reduce the amount of shift between the captured image of the image capturing means 26 and the captured image of the temperature detecting means 27. [

The imaging means 26 or the temperature detecting means 27 may be located at the top of the front panel 15 so that a wider range of the room can be seen at the same angle of view.

Next, the image pickup by the image pickup means 26 and the temperature detection means 27 will be described with reference to Figs. 3A and 3B. The image pickup means 26 is constituted by a CCD image sensor 26b of 640 x 480 pixels and the temperature detecting means 27 is constituted by a thermopile 27b of 1 x 8 pixels. A lens is provided on the front surface of the CCD image sensor 26b and the thermopile 27b, and a visual image is imaged on the sensor.

The detecting element of the thermopile 27b is a heat-receiving element arranged one-dimensionally. As shown in FIG. 3A, the thermopile 27b is rotated by using the arrangement direction of the detection elements as the rotation axis, and scanning is performed in a direction perpendicular to the arrangement direction of the detection elements. Thus, a two-dimensional radiating image of eight pixels in the longitudinal direction can be obtained. The number of pixels in the scanning direction (horizontal direction) of the acquired image will be described later.

The CCD image sensor 26b is a two-dimensional image pickup device. However, in order to widen the range of images captured by the image pickup means 26, as shown in Fig. 3B, The sensor 26b is rotated, and scanning in the horizontal direction is performed. Thus, a picked-up image larger than the number of pixels in the horizontal direction of the CCD image sensor 26b can be obtained.

4 is a diagram for explaining the relationship between the rotation angle of the thermopile 27b of the temperature detection means 27 and the CCD image sensor 26b of the image pickup means 26. Fig. Here, the CCD image sensor 26b has an angle of view of 60 degrees, the thermopile 27b has an angle of view of 5 degrees, and the imaging means 26 and the temperature detecting means 27 have a horizontal direction of 150 degrees And an image of the same field of view is acquired.

A solid line in Fig. 4 shows one imaging angle range of the CCD image sensor 26b, and a dotted line shows one detection angle range of the thermopile 27b. As shown in the drawing, the thermopile 27b acquires a radiant heat image for every rotation angle of 5 degrees in the range of 75 degrees from the center in the left and right directions, and the CCD image sensor 26b, Image capturing may be performed at three rotational angles of 45 deg.

5A and 5B are diagrams showing the imaging results of the imaging means 26 and the temperature detection means 27, which have taken images under the above conditions. The image pickup means 26 can take an image of 1600 x 480 pixels in the horizontal direction at an angle of view of 150 °. The temperature detection means 27 can obtain a thermal image of 30 x 8 pixels in the horizontal direction at an angle of view of 150 °.

At this time, since there is an overlapped area in the captured image by the image pickup means 26, the image of the number of pixels is obtained by appropriately eliminating or averaging.

The number of pixels of the acquired image is an example, and it goes without saying that various choices can be made depending on the angle of view to be acquired and the type of the CCD image sensor 26b or the thermopile 27b to be used.

On the other hand, the resolution of the thermopile 27b seems to be low at first. However, if the temperature distribution of the room is used for controlling the blowing of the air conditioner as in the embodiment, the above resolution can be sufficiently controlled. Needless to say, of course, a high resolution is preferable.

Next, a mechanism for rotating the thermopile 27b or the CCD image sensor 26b will be described. 6A and 6B are diagrams showing an outline of the mechanism. Here, the stepping motor 42 is used as a driving source for rotating the thermopile 27b or the CCD image sensor 26b. 6A and 6B,

6A, a rotary shaft for rotating the thermopile 27b or the CCD image sensor 26b and a drive shaft for the stepping motor 42 are connected via gears. Even if the stepping motor 42 has a small number of steps, a desired rotation angle can be obtained by selecting a gear ratio.

In the mechanism shown in Fig. 6B, the rotation shaft for rotating the thermopile 27b or the CCD image sensor 26b and the drive shaft of the stepping motor 42 are connected by a quadrupole link, have.

When the drive shaft is connected by the gear or the link described above, there may be an error in the rotation position accuracy due to the backlash of the gear or the " clearance " of the link. Therefore, it is preferable that the rotation direction of the thermopile (27b) or the CCD image sensor (26b) at the time of image capturing is one direction, so that there is no error in the rotation angle due to the "clearance". Further, an adjustment amount for absorbing the " clearance " may be obtained in advance and the adjustment may be performed when the rotation direction is reversed.

7 is a view showing an imaging state of a vertical section of the temperature detecting means 27. Fig. As described above, the thermopile 27b of the temperature detecting means 27 is composed of eight elements in the longitudinal direction. Radiant heat in the regions 1 to 8 in Fig. 7 is detected by the heat receiving element. As can be seen from Fig. 7, the upper and lower sides of the imaging result correspond to the wall and floor of the room, respectively.

8 is a configuration diagram of the control circuit of the air conditioner of the embodiment.

The CCD image sensor 26b of the image pickup means 26 and the thermopile 27b of the temperature detection means 27 are driven to rotate independently by the sensor rotation control section 50. [ The temperature distribution generation and determination processing unit 5 generates output images of the CCD image sensor 26b and the thermopile 27b in a two-dimensional radiographic image and a picked-up image shown in Figs. 5A and 5B.

The temperature distribution generation / judgment processing section 5 analyzes the above-mentioned two-dimensional sensed image and radiant heat image to calculate the layout state, the presence or absence of a person, the number of persons, the activity rate thereof, and the temperature distribution.

The air conditioning temperature / wind direction processor 6 outputs the calculation result and the input values of the outside air temperature sensor control unit 51, the room temperature sensor control unit 52, the humidity sensor control unit 53, the illuminance sensor control unit 54, The amount of control such as the temperature and air flow rate and direction of the blowing air is determined with reference to the set value by the remote controller 3 communicating with the control unit 55. [

The device control section 7 controls the compressor drive section 22b of the outdoor unit 2, the outdoor fan motor drive section 24, the four-way valve drive section 34, And controls the driving unit 35 to control the refrigerant cycle for performing cooling and heating and controls the operation of the upper and lower wind direction plate driving units 14b and the left and right wind direction plate driving units 13b and the blower fan driving unit 10b to control the blowing direction and the blowing direction of the cooling wind or the heating wind.

The air conditioning temperature / wind direction processing section 6 sets the operation state of the sensor rotation control section 50.

The temperature distribution generation / determination processing unit 5, the air conditioning temperature / airflow processing unit 6, and the device control unit 7 are realized by a program process by a microprocessor.

≪ Example 1 >

As described above, the imaging means 26 and the temperature detection means 27 can independently perform the imaging operation. For this reason, it is assumed that the operation of the image pickup means 26 and the temperature detecting means 27 is changed in accordance with the function of the air conditioner. Herein, the imaging function of the air conditioner is divided into a functional mode (hereinafter referred to as a human monitoring mode) for controlling the temperature, the wind direction and the air flow rate by detecting the entrance / exit of a person, the number of persons or the position / (Hereinafter referred to as a room monitoring mode) for controlling the temperature, the wind direction and the air flow rate by detecting an area where sunlight enters,

In the human surveillance mode, the imaging means 26 and the temperature detection means 27 are operated in parallel to detect the temperature corresponding to the position of the person identified by the imaging means 26 (first operating state). In the room monitoring mode, the imaging means 26 and the temperature detecting means 27 may be operated individually in order (second operating state). Hereinafter, the details of each operation will be described.

The operation of the imaging means 26 and the temperature detection means 27 in the room monitoring mode is shown in Fig. 9A. The horizontal axis of FIG. 9A represents the time variation, and the vertical axis represents the rotation angle of the CCD image sensor 26b and the thermopile 27b. Here, the rotation angle of the vertical axis corresponds to the rotation angle of 30 points of the thermopile of Fig.

In the room monitoring mode of the air conditioner, it is not assumed that a sudden change in temperature occurs due to a change in the indoor situation. Therefore, the imaging means 26 and the temperature detecting means 27 may be operated alternately. First, the image of the room such as the position of the wall and the opening / closing of the door is recognized from the sensed image of the imaging means 26, and the temperature, the direction and the air volume are controlled based on this. Next, the temperature and the wind direction / air amount are feedback-controlled by the change of the temperature distribution detected by the temperature detection means 27. [

Here, the imaging of the CCD image sensor 26b and the thermopile 27b may be performed at an appropriate timing.

Further, in the room monitoring mode, since the image pickup means 26 and the temperature detecting means 27 can be operated at a low speed or a low frequency, it is advantageous in terms of parts life.

In the human surveillance mode, a person is recognized from an image captured by the imaging means 26, and the temperature, wind direction, and wind amount are controlled in accordance with the amount and position of the person. Therefore, in order to reduce the timing deviation of the person recognition and the temperature detection, the rotation of the image pickup means 26 and the temperature detection means 27 is operated in parallel. Fig. 9B shows the operation of the image pickup means 26 and the temperature detection means 27. Fig.

As shown in Fig. 9B, the thermopile 27b of the temperature detecting means 27 is driven at a constant rotational angular velocity at a detection point of 30 points, and is imaged (signal detected) at regular intervals. On the other hand, the CCD image sensor 26b of the image pickup unit 26 performs a rotating operation for every 10 detection points of the thermopile 27b. The timing of imaging (signal detection) of the CCD image sensor 26b is set to the center of the range of detection points of 10 points of the thermopile 27b. Thus, the timing deviation between the recognition of the person and the temperature detection is reduced.

More specifically, when the thermopile 27b is at the rotation angle of 1 to 9 shown in Fig. 4, the CCD image sensor 26b is in the position of the rotation angle of 1 and the rotation angle of the thermopile 27b is 5, the image of the CCD image sensor 26b is taken.

Next, when the rotation angle of the thermopile 27b becomes 10, the CCD image sensor 26b is driven to the position of the rotation angle 10. [ When the rotation angle of the thermopile 27b reaches 15, the CCD image sensor 26b is imaged.

Further, when the rotation angle of the thermopile 27b reaches 19, the CCD image sensor 26b is driven to the position of the rotation angle 19. When the rotation angle of the thermopile 27b reaches 26, the image of the CCD image sensor 26b is picked up.

≪ Example 2 >

Fig. 10 shows a control flow for reducing the recognition time and the temperature detection timing. In the embodiment described above, the image pickup means 26 and the temperature detection means 27 are operated in parallel to pick up the image pickup means 26 at a predetermined timing. In the present embodiment, the thermopile 27b is rotated at the position of the person who recognized it, and the image is picked up to detect the temperature of the person.

Specifically, the image of the room is picked up by the image pickup means 26 (S101), the image is recognized to specify the position of the person (S102), the rotation angle of the thermopile 27b corresponding to the person position is calculated (S103), the thermopile 27b is driven at the above rotation angle to pick up the image and detect the temperature (S104).

When a plurality of persons are recognized, the temperature is detected by repeating the above-described process for each identified person.

Thus, more accurate temperature measurement becomes possible.

On the other hand, the present invention is not limited to the configuration of the above-described embodiment, but any configuration can be applied as long as the function shown in the claims or the configuration of the present embodiment can be achieved.
