It is comprised so that side air suction part 270 'may open. Thereby, in operation, indoor air is sucked into the indoor unit 2 from the air intake unit 270 'in addition to the air intake unit 270.

The air blower outlet 29 formed in the lower surface of the decorative frame 23 is arrange | positioned under the front panel 25, and communicates with the inside blower air path 290. As shown in FIG. The front upper and lower wind direction plates 291 and the rear upper and lower wind direction plates 292 cover the ejection air path 290 almost in a closed state to form a lower portion of the front face and the bottom of the indoor unit 2. These front upper and lower wind direction plates 291 and rear upper and lower wind direction plates 292 are supported by the rotational shafts provided at both ends, and according to instructions from the remote controller 5, the air conditioner is driven by the drive motor. At the time of operation, the air blowing port 29 is opened to maintain the state by rotating the required angle.

In addition, an auxiliary wind direction plate accommodating portion 290b is provided downstream of the blowing air passage 290, and the auxiliary wind direction plate 291d when the front upper and lower wind direction plates 291 are closed, such as during an operation stop. Is housed.

The indoor unit 2 includes a control unit 10 (not shown), and a microcomputer is installed in the control unit 10. This microcomputer receives signals from various sensors, such as an indoor temperature sensor, an indoor humidity sensor, a sound sensor, a pyroelectric infrared sensor, and a radiation sensor, and transmits an infrared signal with the remote controller 5 via the transceiver 396.

Based on these signals, the microcomputer controls the blower side flow fan 311, the movable panel drive motor, the vertical wind direction drive motor, the left and right wind direction drive motors, and the like, and is in charge of communication with the outdoor unit 6. , And controls the indoor unit (2) collectively.

At the time of stopping the operation of the air conditioner, as shown in FIG. 2, the movable panel 251 closes the front side air intake 230 ′, and further includes the front upper and lower wind direction plates 291 and the rear upper and lower wind directions. The plate 292 is controlled to close the air jet port 29. The left and right wind direction plates 295 are rotated by the drive motor using the rotary shaft provided at the lower end as a support point, and are rotated and maintained in the state according to the instruction from the remote controller 5. Thereby, the blowing air blows off in the desired direction to the left and right. Further, by instructing from the remote controller 5, the front upper and lower wind direction plates 291, the rear upper and lower wind direction plates 292, and the left and right wind direction plates 295 are periodically oscillated during operation of the air conditioner, thereby widening the room. You can also send blowout air periodically.

The drain pan 35 is disposed below the lower ends of the front and rear sides of the indoor heat exchanger 33, and is installed to receive condensed water generated in the indoor heat exchanger 33 during the cooling operation or the dehumidification operation. The collected condensate is discharged to the outside through the drain pipe 37.

Then, in the state where the front upper and lower wind direction plates 291 are closed, the front upper and lower wind direction plates cover the inner decoration surface 24 formed between the air intake part 270 'and the air jet port 29. 291 is disposed in front of the inner decorative surface 24.

Reference numeral 17 denotes a pyroelectric infrared sensor, reference numeral 18 denotes a radiation sensor using a thermopile, reference numeral 19 denotes a sound sensor using a microphone or the like, and any one of the front upper and lower wind direction plates 291 above the air jet port 29 is provided. It is mounted on the back portion of the inner decorative surface 24 on the inner side of the.

The auxiliary wind direction plate accommodating portion 290b that extends upward from the jet air path upper wall 290a downstream of the jet air path 290 is provided so that the front and upper wind direction plates 291 are very weak in cooling or heating operation. ), Slightly upward, and the rear upper and lower wind direction plates 292 are almost closed. The blower crossflow fan 311 is operated at an appropriate rotational speed, and very weak wind flows through this portion. As a result, the blowing air can be passed through the auxiliary wind direction plate accommodating portion 290b as very weak winds, gently diffused into the room, and weak cooling or heating can be performed.

In addition, by using the auxiliary wind direction plate accommodating portion 290b, a short circuit operation for immediately sucking the blown-out wind from the air intake portion 270 'is performed to dry the heat exchanger or to deodorize the inside of the air conditioner. It is also possible to make maintenance operation of air conditioners, such as these.

In addition, when the air conditioner is stopped, the auxiliary wind direction plate 291d and the arm 291e are stored in the auxiliary wind direction plate storage part 290b, and it can be made a neat design without excess unevenness, and disturbs the atmosphere of an interior. It doesn't happen.

Next, arrangement | positioning of a sound sensor, a pyroelectric infrared sensor, and a radiation sensor is demonstrated using FIGS. 3-10.

First, the sound sensor will be described with reference to FIGS. 3 to 8. 4 is a front view when driving the indoor unit. 5 is a bottom view of the indoor unit during operation. 6 is a cross-sectional view of the indoor unit during heating operation. 7 is a sectional view of the indoor unit during cooling operation. 8 is a perspective view of a sound sensor mounting portion of the indoor unit.

The mounting position of a sound sensor is shown by AA of FIG. 4, and the AA cross section is shown in FIG. 4 shows the heating operation.

As shown in FIGS. 4 to 6 and 8, the sound sensor 19 is located in the left and right directions inside the air blower outlet 29, preferably in the center of the air blower outlet 29, and the up and down direction of the air suction. Between the portion 270 'and the air blower outlet 29, preferably from the lower portion 290c of the upper portion of the blowing air passage upper wall 290a to the air intake portion 270' from downstream, and preferably the auxiliary wind direction receiving portion ( 290b from the rear side of the interior decoration surface 24 from the air intake 270 '.

The communication hole 24b is formed in the inner decoration surface 24 facing the sound sensor 19 arranged in this way, and the sound of the room is transmitted to the sound sensor 19 efficiently. For this reason, the sound sensor 19 is covered by the inner decorative surface 24, and it is not visible from the room, and the visible object is only a small communication hole 24b open to the inner decorative surface 24, thereby disturbing the indoor atmosphere. It doesn't happen.

In addition to the sound of the room, the sound sensor 19 receives the driving sound of the air conditioner itself. Since the sound of the air conditioner itself acts as noise when trying to grasp the situation in the room by sound, it is necessary to prevent the sound sensor 19 from being picked up as much as possible. The sound of the air conditioner itself is mostly airflow by the blower crossflow fan 311, and the influence thereof can be reduced by separating the air conditioner from the blower crossflow fan 311, the intake airflow, and the blowdown airflow as much as possible.

In the present invention, in order to make the sound of the air conditioner itself reaching the sound sensor 19 as small as possible, to separate it from the blower crossflow fan 311 as much as possible, and to reduce the influence of the disturbance of the jet airflow, the flow velocity is The communication hole 24b which delivers a room sound to the sound sensor 19 was formed in the position downstream from the lowermost part 290c of the upper part of the blowing air passage upper wall 290a.

From the auxiliary wind direction plate accommodating portion 290b, the communication hole 24b is provided in a range of 30 degrees to 40 degrees of elevation angle from the sound sensor 19 which is spaced apart from the jet airflow and which is easy to pick up the sound of the area where the occupant is. In the inner decoration surface 24 over the air intake 270 ′, a communication hole 24b is formed in which the sound of the room is transmitted to the sound sensor 19.

Further, by making the left and right direction approximately the center of the ejection opening, the communication hole 24b is located at the position farthest from the intake airflow sucked from both ends of the open movable panel 251 when the indoor unit 2 is operated. The influence of can be made small.

In addition, when dust accumulates on the filters 231 and 231 ', and it is easy to occur when the airflow resistance of the airflow increases, the surging phenomenon occurs even at the wing end of the blower crossflow fan 311 even when the surging phenomenon of the fan occurs. There are many, and the influence on the sound sensor 19 placed in the center part of the air blower outlet 29 can be made small.

Moreover, the communication hole 24b is formed in the bottom face of the recessed part 24a formed in the internal decoration surface 24. As shown in FIG. The recessed part 24a is expanded in the shape which spreads forward from the bottom face toward the opening end part of the front face, for this reason, the sound of the room which reached the wide opening end part is amplified while advancing toward a narrow bottom face, and a communication hole 24b is reached, and the sound sensor 19 is received. Thereby, the small sound of the room can also be captured.

Next, the pyroelectric infrared sensor and the radiation sensor will be described with reference to FIGS. 3, 9, and 10. 9 is a perspective view of the pyroelectric infrared sensor mounting unit of the indoor unit. 10 is a perspective view of a thermo pile mounting part of the indoor unit.

Similar to the sound sensor 19, the pyroelectric infrared sensor 17 is also positioned inside and outside the air blower outlet 29, preferably in the center portion of the air blower outlet 29, and the up and down direction of the air intake unit 270 '. Between the air blower 29 and the air inlet 270 ′ from the lower end 290c of the upper part of the blower path upper wall 290a, preferably from the auxiliary wind direction accommodating portion 290b. It is placed in the back portion of the inner decorative surface 24 over the portion 270 '.

Fresnel lens 17a is indispensable for pyroelectric infrared sensor 17, and since the conductor becomes large, even if a small opening is covered with an empty decorative surface in order to make it inconspicuous from the room, it is unreasonable. For this reason, the superpower bar 17b made of infrared ray transmissive material is mounted in front of the pyroelectric infrared sensor 17, and the pyroelectric opening 24c is provided in the corresponding part of the inner decoration surface 24 to match the color and shape. It is configured as if it is one, so that it is inconspicuous from the room.

Similarly to the sound sensor 19, the radiation sensor 18, which is a kind of infrared sensor, is also positioned inside and outside the air blower outlet 29. Preferably, approximately the center of the air blower outlet 29 and the up and down direction are air. Between the intake section 270 'and the air blower outlet 29, preferably from the lower end 290c of the upper part of the blower air passage 290a to the air inlet 270' from the downstream side, and preferably the auxiliary wind direction plate accommodating portion. It is placed in the rear part of the inner decoration surface 24 from 290b to the air intake 270 '.

In the portion of the inner decorative surface 24 that faces the radiation sensor 18, similarly to the sound sensor 19, a concave portion 24a of forward magnification is formed, and a small radiation opening 24d is formed at the bottom of the radiation sensor. A hole is formed in accordance with the shape of (18), and the temperature of the floor surface or the wall surface of the room is detected.

Next, the sensor module which summarized these three sensors is demonstrated using FIGS. 11 is a perspective view of a sensor module of an indoor unit.

The sound sensor 19, the pyroelectric infrared sensor 17, and the radiation sensor 18 described above are compactly arranged in one case as shown in Fig. 11 to improve the function and reduce the cost. Each sensor is mounted on a common substrate subjected to printed wiring, simplifying wiring such as arranging power supplies, making handling easier, and reducing manufacturing costs.

In addition, since the sound sensor 19, the pyroelectric infrared sensor 17, and the radiation sensor 18 are arranged in a narrow range, the detection areas of the respective sensors are almost the same, so that the situation of the detection area is changed to a sensor having different properties. By detecting and analyzing at the same time in a multiple way, the situation of the detection area can be grasped more accurately, and the completion of energy saving operation, comfort operation and automatic operation of the air conditioner can be improved.

Next, the vacuum cleaner of a filter is demonstrated using FIG. 12, FIG. 12 is a top view of the indoor unit. Fig. 13 is a perspective view of the filter cleaning mechanism part of the indoor unit, and (b) is a perspective view showing only the brush.

The cleaning mechanism 230 includes a sweep mechanism 233 sweeping the filters 231 and 231 'with the brushes 267 and 267', and dust collecting parts 280 and 280 'for storing dust collected on one side. In the embodiment, planar filters 231 and 231 'are provided on orthogonal surfaces facing the air intake portion 270 and the air intake portion 270' upstream of the indoor heat exchanger 33. The filters 231, 231 ′ are hooked to the guide frame 234, and the guide frames 234 intersect the rails 235, 235 ′ at the upper rear portion and the lower front side, and the intersection of the filters 231, 231 ′. The propelling shaft 243 is provided in the part.

Here, when the part having the same function exists for the upper filter 231 and the front filter 231 ', the part for the front filter 231' is attached | subjected to the code | symbol of the part for the upper filter 231. Distinguish by attaching "'".

The propulsion shaft 243 has a polygonal cross section and is axially supported by a bearing 245 provided in the guide frame 234, and is provided through a gear mounted at one end passing through the bearing 245 on one side. It is connected to the moving motor 242 fixed to). The screw 244 and the carriage 261 are loosely mounted to the propulsion shaft 243, and the screw 244 is engaged with the rack 237 parallel to the propulsion shaft 243, which is installed in the guide frame 234.

Between the carriage 261 and the rails 235, 235 ′, the brush support frames 262, 262 ′ span across the filters 231, 231 ′, respectively, and the brush support frames 262, 262 ′ have a filter ( 231 and 231 'are attached with brushes 267 and 267' for sweeping and cleaning.

Thus, by rotating the motor 242 for movement, the propulsion shaft 243 and the screw 244 rotate, and along the rack 237, the screw 244 in the left and right directions along the rotational direction of the motor 242 for movement. By moving, the carriage 261 is moved. As a result, the brushes 267 and 267 'are moved to sweep while slidingly contacting the filters 231 and 231', and the dust on the filters 231 and 231 'is removed by the brushes 267 and 267' and the guide frame is removed. It moves to the dust collection parts 280 and 280 'of the left part of 234.

The dust collectors 280 and 280 'remove and store dust attached to the brushes 267 and 267'. It is also a cleaning part of the brushes 267 and 267 'for cleaning the brushes 267 and 267' and preparing for the next cleaning.

Next, the structure and operation | movement of a cleaning mechanism are demonstrated using FIG. It is explanatory drawing of the removal operation | movement of the collection dust of a cleaning mechanism.

On the right side of the filters 231 and 231 'are waiting sections for the brushes 267 and 267' to wait when no cleaning operation is performed.

When the cleaning operation is performed, the sweep mechanism 233 is driven to sweep the filters 231 and 231 'with the brushes 267 and 267' waiting for the waiting portion as shown in part A of FIG. It moves to the C part of FIG. At this time, the hair tips of the brushes 267 and 267 'are raised while gradually bending the hair tips to the surface of the filters 231 and 231' which protrude slightly from the open state of the recess A through the inclination, and the filters 231 and 231. Make sure sliding contact with ').

The brushes 267 and 267 ′ sweep the filters 231 and 231 ′ while moving in the direction of the dust collector 280, and remove the dust 236. Brushes 267 and 267 'having finished sweeping the filters 231 and 231' pass through the portion D of FIG. 14 together with the dust 236 removed to reach the dust collectors 280 and 280 ', and the dust 236. Is removed, and the removed dust 236 is stored in the dust collectors 280 and 280 ', and the brushes 267 and 267' are cleaned.

By mounting the cleaning mechanism 230 of such filters 231 and 231 ', for example, the cleaning mechanism 230 is automatically operated according to the cumulative operating time of the air conditioner, and the filters 231 and 231' are cleaned. Thus, it is possible to prevent the dust from accumulating excessively on the filters 231 and 231 ', and to prevent the surging phenomenon of the blower side flow fan 311 which occurs when the dust accumulates excessively on the filters 231 and 231'.

Thus, the air conditioner of an Example has a sound sensor, forms the communication hole which communicates with the said sound sensor, and the position of the said communication hole is inward of the both ends of a blower outlet in the axial direction of a cross flow fan, and the top of a blower air path It is arrange | positioned between the lowest end of an inlet, and a suction port, A filter is provided in the said suction port, and the automatic cleaning apparatus of the said filter is installed.

In general, the sound generated by the air conditioner may be caused by air flow or refrigerant flow, the driving sound of various actuators, etc., but in recent years, the silence is progressed, and the sound caused by the refrigerant flow and the driving sound of various actuators are greatly reduced. have. Although the sound caused by the airflow is also reduced, most of the sound caused by the airflow is caused by vibration of the member exposed to the airflow and turbulent vortex of the airflow itself, and it is difficult to enclose them.

In recent years, in order to improve the operability of the air conditioner, a product has been discovered that is equipped with various sensors, grasps the situation in the room, and automatically changes the operating state of the air conditioner to suit their situation.

In the air conditioner of the embodiment, since the sound sensor for detecting the sound of the room is provided at the position of the periphery of the jet port toward the room, it is possible to accurately grasp the sound of the room. In addition, since the ejection port is avoided and disposed at the periphery thereof, it is difficult to be affected by the sound caused by the airflow and the sound carried by the airflow, so that the sound of the room can be detected more accurately.

In addition, the automatic cleaning device for the filter is installed so that dust does not accumulate excessively in the filter, so that surging phenomenon that is liable to occur due to excessive accumulation of dust in the filter is less likely to occur. Can be.

Because of this, it is difficult to be influenced by the blowing sound, and the sound of the room can be detected accurately, and the surging of the cross flow fan is hardly generated. Therefore, the detection of the room sound is excellent, and the activity of the occupant is estimated by the sound of the room To provide an air conditioner having a configuration suitable for the purpose of performing operation control.

Further, the air conditioner of the embodiment is mounted, mounted, or housed in the same substrate, sensor base, or case in which the sound sensor and the pyroelectric infrared sensor or the thermopile are identical.

This simplifies the wiring connecting the respective sensors and the control unit, thereby reducing the cost. In addition, since each sensor is disposed at almost the same position of the air conditioner, the area to be detected by each sensor is almost the same, and since each sensor detects the information of this almost same detection area almost simultaneously according to its characteristics, the detection area The state of can be understood more accurately.

For this reason, it is suitable for resource saving, cost can be reduced, the state of a detection area can be grasped | ascertained more accurately, and the air conditioner which air-conditions a room can be provided suitably.

Moreover, the air conditioner of an Example is arrange | positioned so that the said sound sensor and the said pyroelectric infrared sensor or a thermopile may be centered between the said blower outlet center of the said crossflow fan axial direction.

Generally, the air conditioner is installed at a position where the occupants can efficiently air condition the usual range. Such a position is a position in which the occupants adequately circulate the usual range without disturbing the air emitted from the air conditioner, and is often, for example, the center of the barrier. Such a position is also a position where the occupants often look at the usual range, and is often suitable for the occupants to collect the information of the usual range completely.

In the air conditioner of the embodiment, since each sensor mounted on the same substrate (hereinafter referred to as a sensor group) is disposed at a position close to the center of the jet port, the occupant can detect information in the usual range according to the characteristics of each sensor. As a result, indoor information can be collected efficiently.

In addition, when the air conditioner is provided at the corners where the walls intersect, it is considered that the detection accuracy of each sensor is degraded due to the sound reflected from the adjacent wall or the infrared rays, but the distance from the adjacent wall to the sensor group is at least at least. Since the distance of about half or more of the long side dimension of the blower opening of an air conditioner can be ensured, the deterioration of the detection accuracy of a sensor group can be suppressed, and the bad influence by reflection and reflection when it is installed in the corner part of a room can be reduced. have.

In the case where the sensor group is arranged near the short side of the jet port, it is necessary to add another sensor or to adjust the sensor according to the installation position of the air conditioner to compensate for the effects of reflection and reflection as described above. Although generated, by arranging the sensor group near the center of the jet port, the adjustment of these additional sensors and sensors is unnecessary, and the cost can be reduced.

In addition, even if the above-mentioned surging phenomenon occurs unexpectedly, the surging phenomenon starts from the wing end portion of the cross flow fan, so that the influence on the sound sensor disposed at a position close to the center of the ejection port is separated from the surging portion. small.

For this reason, it is possible to provide an air conditioner that efficiently collects necessary information in the room by a small number of sensors and controls it appropriately.

In addition, the air conditioner of an Example may represent the maximum value of the mutual distance between the said sound sensor and the pyroelectric infrared sensor or the center part of a thermopile by the three-dimensional rectangular coordinate which makes the axial direction of the said crossflow fan the X coordinate axis. At that time, the value of the X coordinate is larger than that of the other coordinate axes.

Thereby, the sound sensor, the pyroelectric infrared sensor, and the thermopile are arranged long in the axial direction of the cross flow fan, and are accommodated in the elongated space between the jet port and the suction port without excessive force.

For this reason, it is possible to provide an air conditioner in which the empty space can be effectively utilized and the enlargement of the housing can be suppressed.

Next, the structure of the front upper and lower wind direction plates 291 will be described with reference to FIGS. 15 to 18. Fig. 15 is a cross-sectional view of the sound sensor mounting unit when the front windshield of the indoor unit is closed. 16 is a detail view of the front upper and lower wind direction plates. 17 is a front view of the sensor mounting part when the front upper and lower wind direction plates are opened. 18 is a front view of the sensor mounting part when the front upper and lower wind direction plates are closed.

In FIG. 16, the front upper and lower wind direction plates 291 according to this embodiment include a transparent member 291a formed of a transparent material and an opaque member having a size that fits within the projected area of the transparent member 291a. 291b).

In this embodiment, the transparent member 291a is protruded and formed on the front end side of the front upper and lower wind direction plates 291.

That is, the opaque member 291b of this embodiment extends the arm 291e which is inclined on both sides and the center of the thin plate-shaped base portion 291c having the depth dimension d3 to one end side in the depth direction. The bearing 291f is formed at the end of the arm 291e. In addition, an auxiliary wind direction plate 291d is arranged between the arms 291e to be arranged in alignment with the base portion 291c.

On the other hand, the transparent member 291a is a transparent thin member having a depth dimension d1. This transparent member 291a is formed so that the edge part of the arm 291e side substantially matches, and protrudes more than the edge part of the opaque member 291b by the depth dimension d5 on the other end side. And the transparent member 291a performs back surface printing in the range of the back surface which contacts the opaque member 291b.

That is, the transparent member 291a divides the back surface side into two with respect to the depth direction, performs back surface printing on the arm 291e side used as the rotating shaft side, and transparently makes the other end side used as the front end side with respect to the bearing 291f. Forming. This makes it possible to make the opaque member 291b unnecessary in design and to make the front end of the front upper and lower wind direction plates 291 transparent, thereby improving the design and improving the design of the front upper and lower wind direction plates 291. A feeling of pressure with movement can be reduced. For example, the opaque processing part of a transparent member can cover so that the shaft part etc. which support a wind direction plate cannot be seen, and also the additional function parts, such as a human body detection sensor and a microphone, can be made invisible.

That is, as shown in FIG. 15, in the stopped state of the air conditioner, the front upper and lower wind direction plates 291 are stored adjacent to the lower end of the movable panel 251 covering the front of the air intake 270 ′. can do. Therefore, in the storage state of the front upper and lower wind direction plates 291, since the tip portion of the front upper and lower wind direction plates 291 is formed to be transparent, the inner decorative surface 24 is visually recognized by the user through this transparent part.視 認) In this embodiment, the internal display part 22 which displays a driving state can be provided in the internal decoration surface 24 which can be visually recognized by a user, even if it is a driving state or a driving stop state.

As shown in Fig. 16, in the stationary state of the air conditioner, a band-shaped inner display portion is formed on the inner decorative surface 24 visible through the transparent member 291a at the front end of the front upper and lower wind direction plates 291. 22). Therefore, the display and various sensors can be provided in the internal display part 22 which can be visually recognized, regardless of the operation | movement of the front upper and lower wind direction plates 291. FIG. As shown in FIG. 18, in the embodiment, the operating state is displayed on the internal display unit 22 in a line in the lateral direction. In addition, the pyroelectric infrared sensor 17, the sound sensor 19, and the radiation sensor 18 which operate at the time of operation are arrange | positioned at the back surface side of the inner decoration surface 24 concealed by the front upper and lower wind direction plates 291. Doing.

Thus, the sound sensor 19, the radiation sensor 18, and the pyroelectric infrared sensor 17 are arrange | positioned at the back surface side of the inner decoration surface 24, and the front upper and lower wind direction plates 291 are closed in front of it. When the opaque member 291b is disposed so that the front upper and lower wind direction plates 291 are closed, the sound sensor 19, the radiation sensor 18, and the pyroelectric infrared sensor 17 are closed as shown in FIG. The opening of the is not visible from the room, resulting in a neat appearance.

In addition, when the operation of the blower side flow fan 311 is suspended because the temperature of the indoor heat exchanger 33 is low during the heating operation, the display of the heat is required. As shown in FIG. 17, the indicator light of the sensor module 16 is displayed through the upper part of the transparent member 291a on the upper part of the front upper and lower wind direction plates 291, the display window 22b, and the display opening 22a. 397a) can be visually recognized, so that the display function can be maintained to convey appropriate information to the user.

In operation of the air conditioner, as illustrated in FIG. 18, the sound sensor 19, the radiation sensor 18, the pyroelectric infrared sensor 17, and the front upper and lower wind direction plates 291 that block the living space in the room are opened. By exerting the function of each sensor, the wind direction is controlled.

At this time, the internal display unit 22 is exposed to visually recognize the indicator 397a of the sensor module 16.

Thus, the air conditioner of an Example is provided with the shielding member which makes it difficult to show the said sound sensor, a pyroelectric infrared sensor, or a thermopile.

As a result, when the air conditioner is stopped, the sound sensor or the infrared sensor is covered by the shielding member, and a neat design without excess irregularities can be achieved, and the atmosphere of the interior is not disturbed.

For this reason, the air conditioner which does not disturb the atmosphere of an interior at the time of nonuse can be provided.

Moreover, the air conditioner of an Example is arrange | positioned at the horizontal direction of the axis | shaft of the said crossflow fan, and the said blowing port, and the said shield member moves in conjunction with an up-down wind direction plate.

Thereby, this invention can be employ | adopted for the wall-mounted indoor unit which occupies many in the domestic air conditioner, and the effect can be applied to a wide range of air conditioner.

Thus, by interlocking with the up-and-down wind direction plate, at the time of stopping operation | movement which does not use a sound sensor and an infrared sensor, as shown in FIG. 2, the front part up-down wind direction plate, the rear part up-down wind direction plate, and the movable panel are controlled by the air blower outlet. Since the front side air intake is controlled to close, the front upper and lower wind direction plates are rotated and stored at a position in front of the auxiliary wind direction plate accommodating portion, and shield the sound sensor, the infrared sensor, and the air path auxiliary wind direction plate accommodating portion, In cooperation with the wind vane, the outlet is closed.

At this time, the outer wind direction surface of the front upper and lower wind direction plates is made into a curved surface with a large smooth curvature, and conforms to the external shape of an air conditioner. By doing in this way, the front upper and lower wind direction plates and the rear upper and lower wind direction plates can smoothly form the external shape of the front surface and the bottom surface of an air conditioner on the wind direction surface used as an outer surface. In this way, when the sound sensor is not used, there is no unnecessary irregularities and a smooth and stable appearance does not disturb the atmosphere of the room.

For this reason, the air conditioner which does not disturb the atmosphere of an interior at the time of nonuse can be provided.

Moreover, the air conditioner of an Example is the said shield member comprised by a part of upper and lower wind direction plates.

As a result, by using the front upper and lower wind direction plates as a shielding member, a dedicated shielding mechanism and a shielding member driving section are unnecessary, resource saving can be achieved, and mass and cost can be reduced. In addition, the exclusive shield member driving software is not required, and the development cost can be reduced.

For this reason, it is suitable for resource saving, can reduce cost, and can provide the air conditioner which sends the airflow which air-conditioned according to the position of the occupant at the time of use.

Further, the air conditioner of the embodiment makes it difficult to see the sound sensor, the pyroelectric infrared sensor or the thermopile from the room when the sound sensor, the pyroelectric infrared sensor or the thermopile is not used.

In this way, when the sound sensor is not used at the time of stopping, the blower is covered with a top and bottom wind direction plate, and the sound sensor is covered to make the design assimilar to the wall by making the irregularities as inconspicuous as possible, and furthermore, in the indoor unit. Prevent dust from invading

For this reason, when the sound sensor at the time of stopping or the like is not used, it becomes the storage assimilated to the atmosphere of the room, and it is possible to provide an air conditioner having an excellent appearance when not in use, without disturbing the atmosphere of the interior.

Moreover, the air conditioner of an Example consists of a front part up-down wind direction plate which the said up-and-down wind direction plate becomes a rear part up-down wind direction plate, and the said shielding member, and forms a transparent part and an opaque part in the said front part up-down wind direction plate.

Generally, a separate type of wall-mounted type is often adopted for home air conditioners in consideration of energy saving performance, design, installation space, etc. In this case, the housing is formed horizontally long, and a crossflow fan is used. Therefore, the form which blows air-conditioning air in a room from a horizontally long blower outlet is used widely. At this time, the jet port is provided from the lower surface of the housing to the lower part of the front surface, and when the air conditioner is not in use, this jet port is blocked and covered with the up-and-down wind direction plate so that it may fuse with the external shape of a housing as mentioned above.

In this case, if the wind direction plate which covered the lower part of the front surface so that it may be familiar with a housing is opened by the predetermined angle corresponding to the operation mode, the front-end part may protrude forward and can give a user a feeling of pressure.

In the air conditioner of an Example, when the front upper and lower wind direction plates which covered the lower part of the front surface so that the housing is familiar, the wind direction is deflected satisfactorily. However, even if the tip portion protrudes forward, the tip portion is formed to be transparent, so that the feeling of pressure is relieved by looking in.

For this reason, the air conditioner which favorably controls a wind direction can be provided, reducing the pressure feeling at the time of the operation | movement of a front upper and lower wind direction plate.

Further, the air conditioner of the embodiment makes it difficult to show the sound sensor, the pyroelectric infrared sensor or the thermopile in the opaque portion when the operation stops, thereby covering the internal display portion with the transparent portion.

As a result, when the air conditioner is stopped, the sound sensor or the infrared sensor is covered by the opaque portion of the front upper and lower wind direction plates serving as the shielding member, thereby making it possible to have a neat design without extra unevenness, and disturb the atmosphere of the interior. It doesn't happen.

In addition, the inner display part is covered with a transparent part, but when the operation stops, the front upper and lower wind direction plates rise to a vertically close angle so as to fuse to the housing. Therefore, when viewed from the bottom like a wall-mounted air conditioner, the indicator of the sensor module As long as it is not lit, the reflection on the surface of the transparent portion is strongly influenced so that the internal display portion of the rear portion becomes invisible, and as in the above, a neat design can be achieved, which does not disturb the atmosphere of the interior.

In addition, even when the front windshield is closed, when the indicator light of the sensor module is turned on, the operation indication can be checked. Therefore, in order to prevent cold wind, such as at the start of heating operation, until the temperature of the heat exchanger rises, With closed, the operating status can be checked accurately even when the fan is not operating or during preheating operation.

For this reason, it is possible to provide an air conditioner capable of accurately confirming the driving state even when the wind direction plate is closed without disturbing the atmosphere of the interior during non-use.

Next, a method of subdividing and detecting the activity amount of the occupant by combining the pyroelectric infrared sensor and the sound sensor will be described with reference to FIGS. 19 to 28. 19 is a relationship between activity content and activity amount.

The purpose of the air conditioner is to make the interior a comfortable environment, but consideration to the global environment is also strongly demanded. To this end, a combination of a pyroelectric infrared sensor and a sound sensor is used to subdivide and grasp the activities of the occupants, to control the air conditioner in detail while considering the comfort of the occupants, and to propose an energy saving operation method. .

Conventionally, it has been practical to use a pyroelectric infrared sensor to detect an activity amount of a patient in the room, to adjust the room temperature low when the activity amount is large, and to adjust the room temperature high when the activity amount is small. However, dividing the activity amount of the occupants into multiple stages using only pyroelectric infrared sensors is difficult unless the number of sensors is increased due to a decrease in the sensitivity of the sensor to a detection error or movement in the direction toward the sensor. Is raised.

MET is used as a unit representing the amount of activity of a person, and the content of the activity and its approximate numerical value are as shown in FIG. On the left side of the drawing, the division of the activity amount when only the pyroelectric infrared sensor is used is described as an example. As described above, in the case where only one pyroelectric infrared sensor is used, the amount of activity is divided into three categories: large, medium, and small, and even when attempting to subdivide more than this, the precision is insufficient for the reasons described above.

On the right side of the figure, an example in the case of dividing the amount of activity by the method of the present invention is described. According to the present invention, the amount of activity can be subdivided in this manner, so that it is possible to operate energy-saving in consideration of comfort with the air conditioning appropriate for the amount of activity of the occupants.

Next, the outline | summary of control of the air conditioner of this invention is demonstrated using FIG. 20 is a control block diagram of the indoor unit.

In FIG. 20, the air conditioner is provided with the control part 10 inside, and controls the indoor unit 2 and the outdoor unit 6 according to the information from various sensors, and the instruction | indication from the remote controller 5. As shown in FIG. The information from the room 900 can include room temperature sensor 11, humidity sensor 12, radiation sensor 18, remote controller ambient temperature sensor 13, remote controller position sensor 14, pyroelectric infrared sensor 17. The sound sensor 19 is introduced into the microcomputer (not shown) inside the control unit 10, and the air conditioner is controlled in accordance with various calculation results.

From the information of the pyroelectric infrared sensor 17 and the sound sensor 19, the activity amount determining unit 45 divides the activity amount of the occupants in multiple stages and transmits the activity amount of the occupant to the temperature shift value setting unit 46 as illustrated in the right side of FIG. do. The temperature shift value setting unit 46 is a temperature shift value based on the information from the calendar information 15 provided in the various sensors and the control unit 10 described above, in addition to the activity amount information from the activity amount determining unit 45. Is calculated and transferred to the target room temperature setting unit 47.

The target room temperature setting unit 47 calculates the target room temperature on the basis of the temperature shift value information from the temperature shift value setting unit 46 and the set room temperature information from the room temperature setting unit 48, and the air conditioning capacity control unit 55 To pass.

The air conditioning capacity control unit 55 sets the compressor rotation speed setting unit 56 and the indoor blower rotation speed setting unit 57 based on the target room temperature from the target room temperature setting unit 47, the intake air temperature information from the room temperature sensor 11, and the like. The compressor speed, the indoor blower speed, and the outdoor blower speed are set by the outdoor blower speed setting unit 58, and the compressor 65, the blower cross-flow fan 311, and the outdoor blower 66 are controlled.

In general, temperature control in the air conditioner causes the ejected air of the air conditioner to circulate and return to the room, and detects the temperature of the intake air sucked into the air conditioner by the room temperature sensor 11, and the intake air temperature is the target. The rotation speed of the compressor 65, the blower 66, and the blower transverse fan 311 are changed to change the temperature, the cooling and heating capabilities are changed, and the temperature of the blown air of the air conditioner is changed. .

At this time, the control of the heating and cooling capacity of the air conditioner is performed according to the intake air temperature and the set temperature of the air conditioner, but the intake air temperature of the air conditioner installed in a high place of the room is located from the floor of the room where the user is located. It is known that it becomes higher than the temperature of the living space to the height position of the, and in order to correct this temperature difference, the intake air temperature is made into the target temperature as the weighted set temperature which added the predetermined value (temperature shift value) to the set temperature. The air conditioner is controlled to approach the weighted set temperature. As a predetermined value, although it differs according to the structure of an air conditioner, operation modes, such as heating and cooling, the value of about -1-5 degree is used.

Next, a description will be given of a method of determining the amount of activity of the occupants by the sound sensor and the pyroelectric infrared sensor. First, an example of a room sound will be briefly described with reference to FIGS. 21 and 22. 21 is a frequency analysis example 1 of the indoor sound, (a) is a frequency analysis example of the air conditioner sound, (b) is a frequency analysis example of the cleaner sound. Fig. 22 shows frequency analysis examples 2 of the room sound, (a) shows frequency analysis examples of fostering, and (b) shows lecture frequency analysis examples of television sound.

It is known that a person's sense of warmth is affected by temperature, humidity, airflow, radiation, clothing and activity. Most modern air conditioners control the indoor temperature only (temperature and humidity on some high-end models) to maintain comfort.

However, if a person's behavior changes indoors, even if the other conditions are the same, the person's sense of heat changes, and in order to maintain comfort, it is necessary to change the temperature (and humidity) according to the person's behavior.

In order to meet such a request, the air conditioner is equipped with a human body detection function, the room temperature is raised or lowered according to the amount of activity of the occupant, and the comfort of the occupant is also shown.

However, in the household telephone products with strict cost constraints, the cost that can be applied to the human body detection function is not large, and a method of higher detection accuracy, which inevitably suppresses costs, is sought.

In the home air conditioner, a method of detecting the movement of the occupant is adopted using a pyroelectric infrared sensor as a human body detecting function.

A pyroelectric infrared sensor is a sensor using a pyroelectric effect in which crystals or resins having a large dielectric constant generate electric charges due to temperature changes, and enable infrared rays emitted from humans to be detected without contact.

By installing a Fresnel lens in front of the pyroelectric infrared sensor, intermittent infrared rays and input to the sensor, it is possible to detect human movement.

Therefore, in the case of detecting the human body using only the pyroelectric infrared sensor, when the movement occurs to the occupant, the output of the sensor is changed, and the movement of the occupant can be detected. If the occupant has no movement, the output of the sensor does not change. Therefore, it is possible to detect that the occupants have no movement.

However, only the presence or absence of the movement of the occupants cannot determine how much activity the occupants are.

Therefore, in order to determine the amount of activity of the occupants, a plurality of pyroelectric infrared sensors are provided, and when the occupants move greatly, the plurality of pyroelectric infrared sensors react, and when the movement of the occupants is small, only one sensor reacts. There was method to discriminate large and small amount of activity of occupant.

In this method, a plurality of pyroelectric infrared sensors are required, which causes a cost increase.

In addition, even if there are a plurality of sensors, there is a problem that the amount of activity is impossible in the case where the movement of the occupant is smaller than the detectable movement of the sensor or in the same operation.

Therefore, when the human body is detected only by the pyroelectric infrared sensor, it can be seen that the determination of the amount of activity is limited.

In the air conditioner of the embodiment, the movement of the occupant is detected using a pyroelectric infrared sensor, which has recently been adopted, and the sound generated at that time is detected by the sound sensor.

When the occupant makes any movement, the sound usually accompanies it. By predicting the various scenes in the room where the air conditioner is installed, it is possible to more accurately grasp the amount of activity of the occupants from the detection result of the infrared sensor and the detection result of the sound sensor.

There are various kinds of sounds that occur in the room where the air conditioner is being driven, but first, the sound of the air conditioner itself, the sound of the inmates talking with each other, the sound accompanied by the inmates moving by deskwork, sewing, and light tidying, and the occupant Even if there are no people, such as the sound generated by operating equipment such as vacuum cleaners, cookers, and already-made items, the sound when the occupants are enjoying television, radio, and audio equipment, and the sound of the clock, the pump of the aquarium fish tank, etc. I have a sound.

These sounds can be divided into those accompanying the activities of the inmates and those not related to the activities of the inmates. Sounds irrelevant to the activities of the occupants include the sound of the air conditioner itself, the sound of televisions, radios, and audio equipment, the sounds of music, the effects of sound, the clock, and the sound of pumps of aquarium fish. Sounds associated with the occupants' activities include conversations, deskwork, sewing, light tidying, vacuum cleaners, cookers, and imagery.

First of all, the sound that is not related to the activities of the occupants, even if there are no people, such as the clock or the sound of the pump of the aquarium, is also called the environmental sound of the room where the air conditioner is installed. You need to distinguish your driving sounds from what you add. Similarly, the voices, music, and effects of television, radio, and audio equipment, which are not related to the activities of the occupants, also need to be distinguished from other sounds as the sounds of the occupants are not related to the activities of the occupants. There is.

In addition, when using a heavy equipment group, such as when using a vacuum cleaner in the sound accompanied by the activities of the occupants, the occupants are also actively moving, so it is necessary to distinguish it from other sounds from the need for proper air conditioning. There is. Similarly, the conversations in the sound accompanied by the activities of the occupants need to use the sound sensor to finely classify the activities of the occupants. If the conversation voice is small, the conversation can be judged to be in a quiet state of rest. If you are loud and continue on the way, you can take advantage of the general tendency to increase the person's activity. Similarly, if you use a group of light-use equipment such as cooking equipment, beauty equipment, or desk-work equipment among the sounds accompanied by the activities of the occupants, the occupants will also be used while moving lightly. It is necessary to distinguish it from the case of the recreation or the conversation with a quiet voice.

In view of the above, the type of sound source to be discriminated is a conversation between the air conditioner itself, a group of broadcast receiving devices such as a television, a group of heavy-use devices such as a vacuum cleaner, a group of light-use devices such as a cooking appliance, and the occupants. Sound sources that cannot be discriminated among them have intermediate movements and sounds, and therefore, they are classified into a group of light use devices.

Looking at the relationship between the types of these sound sources and the value of the active amount MET in Fig. 19, television, music appreciation. 1.0MET, indoor cleaning… 3.0 METs, Cooking… The contents of 2.0METs and conversation / telephone are not shown in Fig. 19, but from 1.0 to 1.8METs from other data, and the air conditioner itself does not change the amount of activity of the occupants. High-value device group ≥ light-use device group ≥ conversation ≥ broadcast receiving device group ≥ air conditioner itself.

It is difficult to predict them one by one because the behavior of the occupants from the interior of the general home varies widely, but divides the behavior of the occupants and the sound of the room at that time into the following two patterns.

1: When a room occupant is active and a sound with activity occurs, the change of fever in a body becomes large. Hereinafter, the kind of the sound source which emits a sound with this activity is called a warm sense fluctuation large sound source.

2: When there is activity of occupant, but there is almost no sound accompanying activity, fever in body changes little. Hereinafter, the kind of the sound source which emits the sound which does not accompany this activity is called a warm sense fluctuation small sound source.

When the indoor sound is caused by a warming fluctuation noise source, the detection result of the pyroelectric infrared sensor is divided into a plurality of stages, and the amount of activity of the occupants is determined according to the stages to control the air conditioner. In addition, in the case where the indoor sound is caused by the warmth fluctuation versus the sound source, if the volume of the sound is large, it is determined that the activity is active, and in the case of the warmth fluctuation noise source, it is determined from the detection result of the pyroelectric infrared sensor. The air conditioner is controlled by determining that the activity amount is larger than that of one occupant.

In this way, based on the detection result of the sound sensor, by dividing the sound source in the room into the group of the temperature fluctuation noise source and the group of the temperature fluctuation versus sound source, the amount of activity of the occupants can be subdivided into more divisions, and the finer control Therefore, the effect of power saving is mentioned while considering comfort.

As the above-mentioned fluctuation noise source, as described above, the air conditioner itself or a group of broadcast receiving device groups such as TV and radio are considered, and as the fluctuation fluctuation versus sound source involving movement of the occupants, the occupants themselves communicate with each other. In addition, groups such as vacuum cleaners for supporting housekeeping, cooking appliances such as juicers, mixers, mixers, and the like, and equipments for use such as dryers and razors can be considered. In this case, although the air conditioner itself and the dialogue are independent sound sources, the air conditioner itself and the dialogue are also expressed in groups for convenience of explanation.

These warmth fluctuations vs. sound sources typically use electric motors internally and support the user's power, speed, etc. Among these, heavy-use apparatus groups, such as a vacuum cleaner and a health promotion apparatus, which require a user's power, are forcibly large user, and the duration is comparatively long. A device group that does not force a user with a large activity other than the medium-use device group and a group other than the above-mentioned sound source group shall be referred to as a light-use device group for convenience.

In this way, the air conditioner itself and the broadcast receiving device group are set to the group of the fluctuation and fluctuation noise sources, and the conversation, the medium-use device group, and the light-use device group are the group of the fluctuation and the sound source, thereby basing the detection result of the sound sensor. By determining the group of the sound source in the room, according to the group of the determined sound source, the sound source can be divided into a group of the temperature fluctuation noise source and a group of the temperature fluctuation versus sound source. With more precise control, the effect of power saving can be mentioned while considering comfort.

From this, sound is divided into plural frequencies by frequency, and the sound size, continuity, irregularity, regularity, intermittent intervals, etc. are evaluated by appropriate indices in each frequency band, so that the type of sound source is relatively inexpensive and simple. It can be seen that can be estimated.

As an example of the sound accompanying the occupant's activity, the results of frequency analysis of the sound of the cleaner and the human voice are shown in FIGS. 21B and 22A. As judged from the figure, the sound of the vacuum cleaner completely includes the sound of the low frequency to the high frequency, the human voice is high and the sound of the frequency is low, and the sound of the low frequency near 1 Hz is superior to other parts. You can see a lot. In addition, the sound of the vacuum cleaner was continuously heard, and it was found that the human conversation had irregular crackdown.

21A and 22B show the results of frequency analysis of the sound of the air conditioner itself and the voice of the television, taking an example of sound unrelated to the activities of the occupants. As can be seen from the figure, the sound of the air conditioner itself is generally small in low frequency and high frequency sounds, and the voice of the television includes high frequency sounds in addition to low sounds. We can see much more than human voices.

Here, the characteristics of each sound source group are compared and discrimination is attempted. In the state where there is no sound accompanied by activity of the occupants, for example, the sound of a wall clock, the sound of the circulation pump of the aquarium fish tank, the sound of the air conditioner itself, etc., which occur even in a room without a person, are detected. The size of is minimized. In this case, the low frequency sound and the high frequency sound are continuously detected at low levels, and the regular result is obtained. This determines that the group of sound sources is the air conditioner itself, when the result of having detected the indoor sound by a sound sensor is below predetermined level, and it is continuous continuously.

Subsequently, when the occupant is cleaning using a vacuum cleaner or the like, the sound of the room can be heard only by the vacuum cleaner without the sound of the conversation or the sound of the television. In this case, a low frequency sound and a high frequency sound are continuously detected at a high level, and the result is that there is almost no level change regularly. Thereby, when the result of detecting the indoor sound by a sound sensor is more than predetermined level and regularly continues at substantially the same level, it determines with the group of sound sources as a heavy use apparatus group.

Next, in the case where the occupants are watching television, radio, or the like, or when the occupants are talking to each other, it is common that the conversations of people have irregularities, a lot of low frequency sounds, and long interruptions. From this, it becomes possible to distinguish it from the sound of the above-mentioned air conditioner itself and the heavy use apparatus group.

Here, it is difficult to determine whether the sound source is from a group of broadcast receiving devices such as a television or a radio, or whether the sound is actually a conversation between the occupants. However, unlike the real conversation, the broadcast does not have silence for a long time, and the high frequency sound which does not appear in the real conversation is inserted by the advertisement or the effect music inserted in the middle. The conversation with the receiving device group can be discriminated.

In the above discrimination procedure, the sound that has not been discriminated from the air conditioner itself, the medium-use device group, the broadcast receiving device group, or the conversation is determined by the light-use device group.

The specific discrimination procedure is given as follows based on the above matters.

Procedure 1. The sound sensor provided in the air conditioner separates and extracts the indoor sound into a low frequency sound and a high frequency sound during operation of the air conditioner.

Procedure 2. The separated sound is sampled for each frequency band at a predetermined sampling period for a predetermined time, and the ratio of the number of times of detection of sound at low frequency (BP) and the ratio of the number of times of detection of sound at high frequency band (HP) are calculated. Shall be.

Procedure 3. The sampling is performed a plurality of times (m times, in the example 10 times), and the sampling results BP ₁ to BP _m and HP ₁ to HP _m are obtained each time.

Step 4. The sound level is determined by the magnitudes of BP ₁ to BP _m and HP ₁ to HP _m .

Procedure 5. The continuity of sound is judged by whether all sampling results are on one side of a predetermined threshold determined for each group of sound sources. You may use this determination method instead of the above determination method of four.

Procedure 6. The regularity of sound is judged by whether the difference between the upper limit, the lower limit of the sampling result and the average value of the sampling result is within the judgment range determined for each group of sound sources.

Step 7. The irregularity of the sound is that the number of times that the sampling result is equal to or greater than the predetermined determination threshold determined for each group of sound sources is equal to or greater than the predetermined lower limit threshold that is determined for each group of sound sources, and is equal to or less than the upper limit count threshold. It is judged whether the above-mentioned conference continuation is interrupted midway.

Step 8. Whether or not there is a long interruption of sound is less than or equal to the predetermined upper limit threshold value BJ, HJ prescribed by the group of sound sources for the number of times that the sampling result is equal to or greater than the predetermined threshold BT, HT set for each sound source group, and Judgment is made as to whether or not the continuation of the conferences having a threshold value of BT and HT or more is interrupted midway and whether the difference between the upper limit, the lower limit of the sampling result and the average value of the sampling result exceeds the predetermined judgment width thresholds BX and HX determined for each group of sound sources. do.

The above procedure is organically combined to determine the type of sound source.

Next, a method of discriminating each sound source described above will be described in detail with reference to FIGS. 23 to 25. Fig. 23 is a sound source determination block diagram. 24 is a decision shear explanatory diagram. It is explanatory drawing of a judgment principal part.

For example, first, by the procedure 1 in Fig. 23, the indoor sound signal is captured by the microphone of the sound sensor 19, converted into an electric signal, amplified, and separated into a plurality of frequency bands (two frequency bands in the embodiment). do. The amplified signal is converted into an electric signal and separated into a band pass filter through which a low frequency sound of 5 kHz or less passes and a high pass filter through a high frequency sound of 4 kHz or more. Is delivered to the computer.

Next, based on the sampling result obtained by step 2 in FIG. 24B, the sizes of BP ₁ to BP _m and HP ₁ to HP _m obtained by step 3 in FIG. 24A are shown in FIG. 25. In step (c) of step (c), if the air conditioner determination threshold BP _a in the low frequency band is less than the air conditioner determination threshold HP _a in the high frequency band, the sound source is aired as shown in FIG. conditioner and determined to be his, BP ₁ to BP _m, HP ₁ to mid-priced service equipment determination threshold BP _h, the high frequency band at a low frequency band by the procedure 4 in a magnitude of the value of HP _m, (e) in Fig. 25 If the value of the heavy-use device determination threshold at HP _h or more, the type of the sound source is a candidate of the heavy-use device group.

Next, in step (e) of FIG. 25, the kind of the sound source becomes a candidate of the heavy-use device group in step 4, and similarly in step 6 of FIG. 25 (e), the upper limit, the lower limit of the sampling result, and the sampling result. If the difference in the average value is within the medium-use device determination width BW _c in the low frequency band and the medium-use device determination width HW _c in the high frequency band, the type of sound source is determined to be the medium-use device group as shown in FIG. . In addition, in the figure, the vacuum cleaner is taken as an example of the heavy-use apparatus group.

If it is determined in (c) and (e) of FIG. 25 that the air conditioner itself is not a heavy-use device group, broadcast reception is performed in a frequency band where the sampling result is low by step 7 in FIG. 25 (g). device decision threshold BP _t, a high-frequency broadcast receiving device determination threshold lower-limit number of times the threshold value of the broadcast receiving apparatus in the number of times or more HP _t broadcasting receiving apparatus group of low frequency band BL _t, broadcast receiving apparatus in the high frequency band of the a lower-limit number of times threshold value HL _t and not more than the upper limit number of times the threshold value of the upper-limit number of times the threshold value of the broadcast receiving device in the low frequency band BH _t, the broadcast receiving device in the high-frequency HH _t or less, and the broadcast receiving device is determined in the lower frequency band If the threshold _t BP, the broadcast receiving apparatus is determined threshold or more successive HP _t in the high frequency band is interrupted, the sound source as shown in (h) of Fig. 25 It is determined that the kind of broadcast receiving apparatus group. In the figure, the television is taken as an example of the broadcast receiving device group.

If it is determined in (g) of FIG. 25 that it is not a broadcast receiving device, the number of times that the sampling result is conversation determination threshold value BP _s or HP _s or more in step 7 is the same in FIG. Lower limit threshold of conversations at low frequencies BL _s , Lower limit threshold of conversations at higher frequencies HL _{s and} higher Upper limit threshold of conversations at lower frequencies BH _s , Upper limit threshold of conversations at higher frequencies When the continuation of the meeting which is equal to or smaller than the value HH _s and which is equal to or larger than the conversation determination threshold values BP _s and HP _s is interrupted in the middle, the type of the sound source is determined to be conversation as shown in FIG. 25 (j).

When it is determined that there is no conversation above, it is determined that the type of sound source is a light use device group as shown in Fig. 25K. This means that if the voice of the conversation becomes louder and the voice to talk continues without interruption, it is not judged to be a conversation, but in such a case, the amount of activity of the person having the conversation is also increasing, and thus, for cooking appliances, beauty equipment, and desk work This is because the control phase of the air conditioner can be regarded as the use of a light use device group because the amount of activity is the same as that of using a light use device group such as a device. In addition, in the figure, the group of light-use devices is described outside thereof.

Next, the decision threshold which plays an important role at the same time as determining a sound source from a sampling result is demonstrated using FIG. It is explanatory drawing of correction by ambient sound.

In the room, there are various sounds, such as the clock, the sound of the pump of the aquarium fish tank, even when the occupant is quiet, and when trying to control the air conditioner by the sound sensor, the sound when the occupant is quiet and the sound of the air conditioner itself. It is necessary to consider the effect of the combined sound. For this reason, in the air conditioner of an Example, at the start of operation, it determines with the above-mentioned method the sound when the occupant is quiet.

If the air conditioner is installed at the first operation and the current operation is the first operation, the reference environmental sound measurement period (in the embodiment, the silent operation) is operated or stopped in a quiet state and the reference environmental sound is measured by the sound sensor. It is measured for 1 minute after being operated or stopped in a state, and the original value stored for each time period is substituted into the reference value in the storage device of the air conditioner.

The average of the sampling results at this time is called an initial value and compared with a reference value defined in the air conditioner itself (approximately equal to the average value of the sampling results when operating in the same environment). In the case where the result of the comparison is a reference value <initial value, in the case of the air conditioner's own decision, even if the room is quiet, the environmental sound of the room other than the sound of the air conditioner itself affects the result. In consideration, the determination threshold of each sound source is corrected.

When the determination result of the sound source is a sound source group other than the air conditioner itself, it is judged that there is a significant sound which cannot be said as the air conditioner itself or the environmental sound, and the determination threshold of each sound source is not corrected. When the result of comparing the initial value with the reference value is a reference value ≥ initial value, since each sound source can be sufficiently identified and determined by the current determination threshold value, the determination threshold value of each sound source is not corrected.

Thus, the air conditioner of an Example sets the determination threshold of the kind of the sound source which determines the kind of sound source based on the detection result of the said sound sensor, and operates it in the quiet state in the room which provided the said air conditioner. Or a threshold value correction section for correcting the determination threshold value according to a detection result (initial value) of the sound sensor in a reference environmental sound measurement period in which the sound sensor measures a reference environmental sound by stopping, and determining the activity amount. The unit determines the type of the sound source according to the determination threshold corrected by the threshold correction unit, and determines the activity amount of the occupant in accordance with the type of the determined sound source and the detection result of the infrared sensor.

Thereby, in the room in which the air conditioner is installed, the detection result of the sound sensor in the state with the smallest sound which can be realized when the air conditioner is operated or stopped can be known. In this case, when the air conditioner is operated, a sound such as a clock, a circulation pump sound of a tubular fish tank, etc., which emits a sound even when the sound sensor itself does not have the sound of the air conditioner itself is detected. In addition, when the air conditioner is stopped, sounds such as a clock of a clock, a circulating pump of a tubular fish tank, etc., which emit a sound even when there is no user in the sound sensor, are detected.

Specifically, the detected value of the sound sensor (this is called an initial value) for a predetermined time (1 minute in the embodiment) during the start of the air conditioner operation or during the stop is compared with the reference value. When the air conditioner is provided and is the first operation or stop, the reference value is the detected value of the sound sensor at the time of operation in the environment or at the same time as recorded in the storage element of the controller in the manufacturing step.

In the case of the reference value? Initial value, the threshold value is not corrected. In most cases, the reference value is the initial value. In this case, when the determination threshold is corrected from the result when the air conditioner is operated, and when the sampling result of the sound sensor indicates that the type of the sound source is the air conditioner itself, the type of sound source is determined. Correct the threshold value. In the meantime, when the sampling result of the sound sensor indicates that the type of the sound source is other than the air conditioner itself, it indicates that a conversation other than the air conditioner itself, the sound of the television, etc. are detected. Since it is not a driving operation, correction is not performed.

Further, when the determination threshold is corrected from the result of stopping the air conditioner, and in the case of the initial value ≤ reference value + standard environmental tuning fork, the threshold for determining the type of sound source is corrected. Here, the standard environmental tuning fork is a value indicating the width of the deviation of the environmental sound, and is a value previously recorded in the storage element of the controller in the manufacturing step. In the case of the reference value + standard environmental tuning fork <initial value, the sampling result of the sound sensor in the meantime indicates that a conversation other than the air conditioner itself, the sound of the television, etc. are detected and is not operated in a quiet state. Do not.

By correcting the threshold value for determining the type of the sound source in this manner, the type of the sound source can be appropriately determined according to the type of the temperature-sensitive variable sound source or the type of the temperature-invariant sound source in accordance with the sound environment of the room in which the air conditioner is installed. In combination with the detection results of the sensor, the amount of activity of the occupants is judged to be high accuracy, and the air conditioner is controlled to raise or lower the room temperature more appropriately while considering comfort in fine control, thereby preventing unnecessary use of energy. , Can contribute to energy saving.

Therefore, it is possible to provide an air conditioner that properly grasps the situation in the room by appropriate correction according to the environmental noise in the room, and aims to save power.

Next, the operation of the pyroelectric infrared sensor will be described with reference to FIG. 27. It is explanatory drawing of reaction detection division determination.

The pyroelectric infrared sensor 17, together with the Fresnel lens 17a, captures a change in the amount of infrared light from the room. When there is active movement in the room, the reaction amount is large, and when it is quiet movement, the reaction amount is small. Using this, the signal from the pyroelectric infrared sensor 17 is amplified through a band pass filter for extracting human motion, digitized and transmitted to a microcomputer embedded in the controller.

The microcomputer samples the digital signal for a predetermined sampling period (10 ms in the embodiment) during the sampling period (60 seconds in the embodiment), calculates the ratio of the reaction detection data in the sampled data, and calculates the reaction detection rate. Get Px

When this reaction detection ratio Px is less than the positive determination threshold Pb which discriminates whether the amount of movement of a room is small, the detection division of reaction is divided into reaction tablets. Next, when the reaction detection ratio Px is equal to or greater than the dynamic determination threshold value Pv for determining whether the indoor motion amount is large, the detection classification of the reaction is classified into the reaction steel. When reaction detection ratio Px is more than fixed decision threshold value Pb, and it is less than copper decision threshold value Pv, the detection division of reaction is divided into the middle of reaction.

Next, a method of subdividing the amount of activity by the combination of the pyroelectric infrared sensor and the sound sensor will be described with reference to FIG. 28. 28 is an activity amount determination diagram in combination.

The activity amount determining unit combines the detection classification of the above reaction with the result of the sound source determination described above, and subdivides the activity amount of the occupants as shown in FIG. Thus, even if the detection classification of the response is the same, in the case of the warmth fluctuation versus the sound source group in which the sound source is accompanied by the activity of the occupant, the amount of activity is judged to be greater than in the case of the warm fluctuation fluctuation noise source group in which the sound source is not related to the activity of the occupant. do. As a result, since the activity amount is divided into five and six steps from the conventional three steps, it is possible to make a very fine control from the conventional.

In the example of FIG. 28, the maximum amount of activity is detected by the pyroelectric infrared sensor, and the amount of activity in the case of warming fluctuation vs. sound source group, in which the type of sound source is the medium-use device group, the dialogue and the light-use device group, is used as the reaction steel. The minimum amount of activity is detected by the pyroelectric infrared sensor, and the detection division is a reaction well to minimize the amount of activity in the case of the warm-sensing fluctuation noise source group in which the sound source is composed of the air conditioner itself and the broadcast receiving device group.

In other parts of the matrix, the magnitude of the activity in the same response detection category in the matrix is the warmth fluctuation noise source group ≤ the warmth fluctuation versus the sound source group, although the magnitude of the activity in the same sound source group is natural, Set the amount of activity to be a relationship.

When the amount of activity of the occupants is small at the time of cooling, since the occupants are quiet and the metabolism is not active, fever decreases in the body, and the thermal sense of the occupants changes to the cold side, so even if the room temperature is raised slightly, comfort is acceptable. It is energy-saving operation only to the extent and raises room temperature slightly. When the amount of activity of the occupants is large at the time of heating, since the occupants are actively moving and metabolism is in active state, fever in the body increases, and the warmth sense of the occupants changes to the hot side, so even if the room temperature is slightly lowered, comfort is within the acceptable range. In addition, it lowers room temperature slightly and becomes energy saving operation.

Next, adjustment of intake air temperature is demonstrated.

In general, in order to save energy by spot-conditioning around the user of the air conditioner, the temperature is sensed at the position of the remote controller placed near the user, and the space around the user is made comfortable. Is done.

At this time, as described above, the control of the heating and cooling capabilities of the air conditioner is performed according to the intake air temperature and the set temperature of the air conditioner, but the intake air temperature of the air conditioner installed in a high place of the room It is known that it becomes higher than the temperature of the living space from the floor of a room to the height position of a face, and in order to correct | amend this temperature difference, the weighted set temperature which added the predetermined value (temperature shift value) to the set temperature is made into the target temperature. The air conditioner is controlled so that the intake air temperature approaches the weighted set temperature. As a predetermined value, although it differs according to the structure of an air conditioner, operation modes, such as heating and cooling, the value of about -1-5 degree is used. However, even when the temperature of the living space is different from the center of the room and the window side, it is common to set the temperature shift value as described above, and the user's place is not necessarily comfortable even when the intake air temperature is close to the weighted set temperature. Also happens frequently. In such a case, it is necessary for the user to find and select a comfortable state by raising and lowering the set temperature.

Today, when the recommended temperature at the time of cooling becomes public, the user needs to be troubled with energy-saving operation of the air conditioner, too, and if the room is made more comfortable than necessary, operation time, power consumption of the compressor of the air conditioner This increases, and does not lead to energy saving operation. For this reason, it becomes an air conditioner caught by the vague anxiety that the indoor state is not too comfortable, or even if it changes to a little more energy-saving driving, and enters the tolerance range of comfort, and it is difficult to raise the result of energy saving driving.

When the room goes from a comfortable state to an unpleasant state, it is possible to reset the air conditioner to a slightly comfortable direction when recognizing that the user is out of acceptable comfort range, but each time the air conditioner is reset. You have to change the setting of, which is cumbersome.

On the other hand, on the way from the unpleasant state to the comfortable state, it is very difficult to have the perception that it is in a comfortable state and has entered the comfortable range at the time of entering the comfortable range, and each time the setting of the air conditioner is changed. In itself, it is not practical.

For this reason, after a long time in a comfortable state, the state that the energy saving operation could be performed a little more often repeats, and the method of solving this is desired.

In order to meet this challenge, in the present invention, the activity amount of the occupant is subdivided from the detection result of the pyroelectric infrared sensor and the sound sensor as above, and the comfort of the occupant is considered in accordance with the segmented activity amount. The temperature shift value is finely corrected, and the trouble that the occupants change the setting every time is reduced, and energy-saving operation of the air conditioner which was practically impossible to realize becomes possible.

Next, the movement of the radiation sensor will be described with reference to FIG. 29. Fig. 29 is an explanatory diagram of the copy amount determination, and (a) is a block amount determination block diagram.

The radiation sensor uses a thermopile, measures the amount of infrared light from the floor, walls, and the like in the room to obtain a radiation temperature. When the walls and the floor of the room are warmed by sunlight, or the temperature is different from the room temperature by another air conditioner or the like, the thermal sense of the occupant is changed, so that room temperature may be changed to save energy.

The signal from the radiation sensor is properly amplified and passed through a band pass filter, digitized and transmitted to the microcomputer.

The microcomputer samples this digital signal during a sampling period at a predetermined sampling period and combines the signal from the room temperature sensor to calculate a temperature difference between the radiation temperature and the room temperature. This sampling and calculation are performed a plurality of times, and the average value of the plurality of times is calculated to be referred to as the radiation temperature difference.

At the time of cooling, when the radiation temperature difference becomes negative, the temperature of the wall and the floor is lower than room temperature, and since the thermal sense of the occupant changes to the cold side, it is possible to maintain comfort even if the temperature is slightly increased, so that the room temperature is slightly raised. As much as it becomes energy saving driving. When the temperature difference of the radiation becomes positive at the time of heating, the temperature of the wall and the floor is higher than room temperature, and the warmth sense of the occupant changes to the hot side, so comfort can be maintained even if I lower the room temperature slightly by that and lowered room temperature slightly As much as it becomes energy saving driving.

As described above, the air conditioner of the embodiment includes, in addition to the above-described configuration, an infrared sensor for detecting the amount of movement of the occupant or the amount of radiation from the floor or the wall of the room, a setting unit at room temperature, a control unit for controlling the operation, and the infrared ray. An activity amount determining unit that determines the amount of activity of the occupants in accordance with the detection result of the sensor and the detection result of the sound sensor, and changes a target value determined based on the set temperature based on the activity determination amount of the occupant determined by the activity amount determining unit; do.

Thereby, based on the detection result of the sound sensor and the pyroelectric infrared sensor which detects the movement amount of the occupant, or the thermopile which detects the radiation amount from the floor or the wall of the room, the activity amount of the occupant and the radiation temperature of the room are estimated, According to the estimation result, the air conditioner is air-conditioned by changing the target value of the predetermined air conditioning based on the set temperature.

That is, the type of the sound source is determined based on the detection result of the sound sensor, and the amount of activity of the occupant is determined by combining the determined type of the sound source and the movement amount of the occupant. The smallest value is used as the temperature shift value, and the smaller the amount of activity is, the larger value is used as the temperature shift value.

By adjusting in this way, the higher the amount of activity during heating, the intake air temperature is adjusted to be slightly lower than the set temperature, while the lower amount of activity during cooling, the intake air temperature is adjusted slightly higher than the set temperature, so that comfort is considered. By precisely controlling the air conditioner, it is possible to determine that the amount of activity of the occupants is high accuracy, even if the sound source is not known, and to control the air conditioner to raise or lower the room temperature more appropriately, thereby preventing unnecessary use of energy. This can contribute to energy saving.

The activity amount of the occupant may be estimated based on the detection result of the sound sensor, and the temperature shift value is determined by dividing the activity amount into large, medium, and small, for example, according to the product of the loudness and the number of appearances. Radiation temperature-room temperature is calculated based on the detection result of a thermopile, For example, it divides into temperature difference positive, temperature difference small, and temperature difference part by the value of radiation temperature-room temperature, The larger the radiation temperature-room temperature, the smaller the value as the radiation shift value and the temperature shift value are used as the temperature shift value.

In this way, by adjusting, the higher the radiant temperature at the time of heating, the intake air temperature is adjusted to be slightly lower than the set temperature, while the lowered radiant temperature at the time of cooling, the intake air temperature is adjusted to be slightly higher than the set temperature, so that comfort is achieved. By carefully controlling the air conditioner, energy-saving operation can be performed.

In this way, by introducing the radiant temperature affecting the thermal sensation into the control of the air conditioner, the air conditioner is controlled while considering the comfort by changing the radiation shift value in accordance with the difference in the radiant temperature-room temperature, thereby providing finer control. By performing the above, energy saving operation can be achieved.

For this reason, the air conditioner which aims at power saving can be provided, taking into account comfort comfort, by estimating the activity amount of the occupant in detail from the detected sound information and the information of an infrared sensor.

In addition, the air conditioner of an Example has a sound sensor, is located in the axial direction of a cross flow fan, inside the both ends of a blower outlet, it is arrange | positioned between the lowest end of the upper part of a blower air passage, and a suction hole, and the communication hole which communicates the said sound sensor and the room, A pyroelectric infrared sensor that detects the amount of movement of the occupant or a thermopile that detects the amount of radiation from the floor or wall of the room, a setting unit of room temperature, a controller for controlling operation, a detection result of the pyroelectric infrared sensor or the An activity amount determination unit for determining the activity amount of the occupants in accordance with the detection result of the thermopile and the detection result of the sound sensor, and based on the activity determination amount of the occupant determined by the activity amount determination unit, Change it.

Thereby, since the sound sensor which detects the sound of the room is installed in the periphery of the jet port toward the room, the sound of the room can be grasped accurately. In addition, since the ejection port is avoided and disposed at the periphery thereof, it is difficult to be affected by the sound caused by the airflow and the sound carried by the airflow, so that the sound of the room can be detected more accurately.

In addition, by using a combination of the detection result of the sound sensor and the detection result of the pyroelectric infrared sensor or the thermopile, as described above, the air conditioner is controlled to raise or lower the room temperature more appropriately in consideration of comfort. Thus, unnecessary use of energy can be prevented, contributing to energy saving.

For this reason, it is hard to be influenced by a blowing sound, and the sound of a room can be detected correctly, and the power consumption of the occupant is estimated in detail from the detected sound information and the information of an infrared sensor, and the power saving is considered, considering comfort. Can provide an air conditioner.

As described above, according to the air conditioner of Claim 1, it has a sound sensor, forms the communication hole which communicates with the said sound sensor, and the position of the said communication hole is located inside both ends of a blower outlet in the axial direction of a cross flow fan. The filter is disposed between the lowermost end of the upper wall of the blowing air passage and the suction port, the filter is provided at the suction port, and an automatic cleaning device for the filter is provided.

Thereby, since the sound sensor which detects the sound of the room is installed in the periphery of the jet port toward the room, the sound of the room can be grasped accurately. In addition, since the ejection port is avoided and disposed at the periphery thereof, it is difficult to be affected by the sound caused by the airflow and the sound carried by the airflow, so that the sound of the room can be detected more accurately.

In addition, an automatic cleaning device for the filter is installed so that dust does not accumulate excessively in the filter, so that surging phenomenon that is likely to occur due to excessive accumulation of dust in the filter is less likely to occur, and silent operation is continued to detect the noise in the room without disturbing. Can be.

Because of this, it is difficult to be influenced by the blowing sound, and the sound of the room can be detected accurately, and the surging of the cross flow fan is hard to occur. Therefore, the detection of the room sound is excellent, and the activity of the occupant is estimated by the sound of the room. To obtain an air conditioner having a configuration suitable for the purpose of performing operation control.

Moreover, according to the air conditioner of Claim 2, In addition to the above, the infrared sensor which detects the movement amount of a occupant or the radiation amount from the floor or the wall of a room, the setting part of room temperature, the control part which controls operation, and the said infrared ray An activity amount determining unit that determines the amount of activity of the occupants in accordance with the detection result of the sensor and the detection result of the sound sensor, and changes a target value determined based on the set temperature based on the activity determination amount of the occupant determined by the activity amount determining unit; do.

Thereby, based on the detection result of the sound sensor and the pyroelectric infrared sensor which detects the movement amount of the occupant, or the thermopile which detects the radiation amount from the floor or the wall of the room, the activity amount of the occupant and the radiation temperature of the room are estimated, According to the estimation result, the air conditioner is air-conditioned by changing the target value of the predetermined air conditioning based on the set temperature.

That is, the type of the sound source is determined based on the detection result of the sound sensor, and the amount of activity of the occupant is determined by combining the determined type of the sound source and the movement amount of the occupant. The smallest value is used as the temperature shift value, and the smaller the amount of activity is, the larger value is used as the temperature shift value.

By adjusting in this way, the higher the amount of activity during heating, the intake air temperature is adjusted to be slightly lower than the set temperature, while the lower amount of activity during cooling, the intake air temperature is adjusted slightly higher than the set temperature, so that comfort is considered. By precisely controlling the air conditioner, it is possible to determine that the amount of activity of the occupants is high accuracy, even if the sound source is not known, and to control the air conditioner to raise or lower the room temperature more appropriately, thereby preventing unnecessary use of energy. This can contribute to energy saving.

The activity amount of the occupant may be estimated based on the detection result of the sound sensor, and the temperature shift value is determined by dividing the activity amount into large, medium, and small, for example, according to the product of the loudness and the number of appearances. The radiant temperature-room temperature is calculated based on the detection result of the thermopile, for example, divided by the temperature difference, temperature difference, and temperature difference part by the value of the radiant temperature-room temperature, and the smaller value is obtained as the radiant temperature-room temperature is larger. A value added to a temperature shift value as a radiation shift value is made into a temperature shift value.

In this way, by adjusting, the higher the radiant temperature at the time of heating, the intake air temperature is adjusted to be slightly lower than the set temperature, while the lowered radiant temperature at the time of cooling, the intake air temperature is adjusted to be slightly higher than the set temperature, so that comfort is achieved. By carefully controlling the air conditioner, energy-saving operation can be performed.

In this way, by introducing the radiant temperature affecting the thermal sensation into the control of the air conditioner, the air conditioner is controlled while considering the comfort by changing the radiation shift value in accordance with the difference in the radiant temperature-room temperature, thereby providing finer control. By performing the above, energy saving operation can be achieved.

For this reason, the air conditioner which aims at power saving can be obtained, taking into consideration the comfort level, by estimating the activity amount of the occupant in detail from the detected sound information and the information of an infrared sensor.

Moreover, according to the air conditioner of Claim 3, it has a sound sensor, is located in the axial direction of a cross flow fan from the both ends of a blower outlet, and is arrange | positioned between the lowest end of the upper part of a blower air passage, and a suction port, and communicates with the said sound sensor and the room. Pyroelectric infrared sensor that detects the amount of movement of the occupant, the occupant or thermopile that detects the amount of radiation from the floor or wall of the room, a setting unit of room temperature, a control unit for controlling the operation, and detection of the pyroelectric infrared sensor An activity amount determination unit for determining the activity amount of the occupants in accordance with a result or the detection result of the thermopile and the detection result of the sound sensor, and is determined based on the set temperature based on the activity determination amount of the occupant determined by the activity amount determination unit. Change the target value.

Thereby, since the sound sensor which detects the sound of the room is installed in the periphery of the jet port toward the room, the sound of the room can be grasped accurately. In addition, since the ejection port is avoided and disposed at the periphery thereof, it is difficult to be affected by the sound caused by the airflow and the sound carried by the airflow, so that the sound of the room can be detected more accurately.

In addition, by using a combination of the detection result of the sound sensor and the detection result of the pyroelectric infrared sensor or the thermopile, as described above, the air conditioner is controlled to raise or lower the room temperature more appropriately in consideration of comfort. Thus, unnecessary use of energy can be prevented, contributing to energy saving.

For this reason, it is hard to be influenced by a blowing sound, and the sound of a room can be detected correctly, and the power consumption of the occupant is estimated in detail from the detected sound information and the information of an infrared sensor, and the power saving is considered, considering comfort. To get an air conditioner.

Moreover, according to the air conditioner of Claim 4, On the basis of the detection result of the said sound sensor, the determination threshold of the kind of the sound source which determines the kind of sound source is set, The quiet state in the room where the said air conditioner was installed, And a threshold correction unit for correcting the determination threshold value according to a detection result (initial value) of the sound sensor in a reference environmental sound measurement period in which the sound sensor measures a reference environmental sound by driving or stopping at The determination unit determines the type of the sound source according to the determination threshold value corrected by the threshold correction unit, and determines the activity amount of the occupant in accordance with the type of the determined sound source and the detection result of the infrared sensor.

Thereby, in the room in which the air conditioner is installed, the detection result of the sound sensor in the state with the smallest sound which can be realized when the air conditioner is operated or stopped can be known. In this case, when the air conditioner is operated, a sound such as a clock, a circulation pump sound of a tubular fish tank, etc., which emits a sound even when the sound sensor itself does not have the sound of the air conditioner itself is detected. In addition, when the air conditioner is stopped, sounds such as a clock of a clock, a circulating pump of a tubular fish tank, etc., which emit a sound even when there is no user in the sound sensor, are detected.

Specifically, the detected value of the sound sensor (this is set as an initial value) for a predetermined time (1 minute in the embodiment) during the start of the air conditioner or during the stop is compared with the reference value. When the air conditioner is provided and the first operation or stop is used, the detection value of the sound sensor at the time of operation in the environment or at the stop is used as the reference value as recorded in the storage element of the controller in the manufacturing step.

In the case of the reference value? Initial value, the threshold value is not corrected. In most cases, the reference value is the initial value. In this case, when the determination threshold is corrected from the result when the air conditioner is operated, and when the sampling result of the sound sensor indicates that the type of the sound source is the air conditioner itself, the type of sound source is determined. Correct the threshold value. In the meantime, when the sampling result of the sound sensor indicates that the type of the sound source is other than the air conditioner itself, it indicates that a conversation other than the air conditioner itself, the sound of the television, etc. are detected. Since it is not a driving operation, correction is not performed.

Further, when the determination threshold is corrected from the result of stopping the air conditioner, and in the case of the initial value ≤ reference value + standard environmental tuning fork, the threshold for determining the type of sound source is corrected. Here, the standard environmental tuning fork is a value indicating the width of the deviation of the environmental sound, and is a value previously recorded in the storage element of the controller in the manufacturing step. In the case of the reference value + standard environmental tuning fork <initial value, the sampling result of the sound sensor in the meantime indicates that a conversation other than the air conditioner itself, the sound of the television, etc. are detected and is not operated in a quiet state. Do not.

Thus, by correcting the threshold value for determining the type of the sound source, it is possible to appropriately determine the type of the sound source according to the sound environment of the room in which the air conditioner is installed, as the type of the temperature-sensitive variable sound source or the type of the temperature-sensitive constant sound source. In combination with the detection result of the infrared sensor, the amount of activity of the occupants is judged to be high accuracy, and the air conditioner is controlled to raise or lower the room temperature more appropriately while considering comfort in fine control, thereby preventing unnecessary use of energy. This can contribute to energy saving.

For this reason, an air conditioner can be obtained by appropriately grasping the situation of the room by appropriate correction according to the environmental noise of the room, and achieving power saving.

Moreover, according to the air conditioner of Claim 5, the said sound sensor and a pyroelectric infrared sensor or a thermopile are mounted, mounted, or accommodated in the same board | substrate, a sensor base, or a case.

This simplifies the wiring connecting the respective sensors and the control unit, thereby reducing the cost. In addition, since each sensor is arranged at approximately the same position of the air conditioner, the area to be detected by each sensor becomes almost the same, and since each sensor detects the information of this almost same detection area almost simultaneously according to its characteristics, the detection area The state of can be understood more accurately.

For this reason, it is suitable for resource saving, cost can be reduced, the state of a detection area can be grasped | ascertained more accurately, and the air conditioner which air-conditions a room can be obtained suitably.

Moreover, according to the air conditioner of Claim 6, the said sound sensor and the said pyroelectric infrared sensor or a thermopile are arrange | positioned across the center of the said blower outlet in the said crossflow fan axial direction.

As a result, each sensor mounted on the same substrate (hereinafter referred to as a sensor group) is arranged at a position close to the center of the jet port, so that the occupant can detect information in the usual range according to the characteristics of each sensor. Information can be gathered efficiently.

In addition, when the air conditioner is installed at the corner where the walls intersect, it is considered that the detection accuracy of each sensor is deteriorated due to the sound reflected by the adjacent wall or the infrared rays, but the distance from the adjacent wall to the sensor group may be reduced. Since the distance of at least about half of the long side dimension of the ejection opening of the air conditioner can be secured, the deterioration of the detection accuracy of the sensor group can be suppressed, and the adverse influence due to reflection and reflection when installed in the corner of the room can be reduced. Can be.

In the case where the sensor group is arranged near the short side of the jet port, it is necessary to add another sensor or to adjust the sensor according to the installation position of the air conditioner to compensate for the effects of reflection and reflection as described above. Although generated, by arranging the sensor group near the center of the jet port, the adjustment of these additional sensors and sensors is unnecessary, and the cost can be reduced.

In addition, even if the above-mentioned surging phenomenon occurs unexpectedly, the surging phenomenon starts from the wing end portion of the cross flow fan, so that the influence on the sound sensor disposed at a position close to the center of the ejection port is separated from the surging portion. small.

For this reason, the air conditioner which collects necessary information efficiently indoors by a small number of sensors efficiently, and controls it suitably can be obtained.

Moreover, according to the air conditioner of Claim 7, the three-dimensional rectangular coordinate which makes the maximum value of the mutual distance between the said sound sensor and the pyroelectric infrared sensor or the center part of a thermopile the axial direction of the said crossflow fan as an X coordinate axis. When expressed by, the value of the X coordinate is larger than that of other coordinate axes.

As a result, the sound sensor, the pyroelectric infrared sensor, and the thermopile are arranged long in the axial direction of the cross flow fan, and are accommodated in an elongated space between the jet port and the suction port without excessive force.

For this reason, an empty space can be utilized effectively, and the air conditioner by which the housing size can be suppressed can be obtained.

Moreover, according to the air conditioner of Claim 8, the sound sensor, the pyroelectric infrared sensor, or a thermopile is provided with the shielding member which makes it hard to see.

As a result, when the air conditioner is stopped, the sound sensor or the infrared sensor is covered by the shielding member, and a neat design without excess irregularities can be achieved, and the atmosphere of the interior is not disturbed.

For this reason, the air conditioner which does not disturb the atmosphere of an interior at the time of nonuse can be obtained.

Moreover, according to the air conditioner of Claim 9, the axis | shaft of the said crossflow fan and the longitudinal direction of the said blower outlet are arrange | positioned in a horizontal direction, and the said shield member moves in conjunction with an up-down wind direction plate.

Thereby, this invention can be employ | adopted for the wall-mounted indoor unit which occupies many in the domestic air conditioner, and the effect can be applied to a wide range of air conditioner.

Thus, by interlocking with the up-and-down wind direction plate, at the time of stopping operation | movement which does not use a sound sensor and an infrared sensor, as shown in FIG. 2, the front part up-down wind direction plate, the rear part up-down wind direction plate, and the movable panel are controlled by the air blower outlet. Since the front side air intake is controlled to close, the front upper and lower wind direction plates are rotated and stored at a position in front of the auxiliary wind direction plate accommodating portion, and shield the sound sensor, the infrared sensor, and the air path auxiliary wind direction plate accommodating portion, In cooperation with the wind vane, the outlet is closed.

At this time, the outer wind direction surface of the front upper and lower wind direction plates is made into a curved surface with a large smooth curvature, and conforms to the external shape of an air conditioner. By doing in this way, the front upper and lower wind direction plates and the rear upper and lower wind direction plates can smoothly form the external shape of the front surface and the bottom surface of an air conditioner on the wind direction surface used as an outer surface. In this manner, when the sound sensor is not used, a smooth and stable appearance without unnecessary irregularities is obtained, and the atmosphere in the room is not disturbed.

For this reason, the air conditioner which does not disturb the atmosphere of an interior at the time of nonuse can be obtained.

Moreover, according to the air conditioner of Claim 10, the said shielding member is comprised by a part of top and bottom wind direction plates.

As a result, by using the front upper and lower wind direction plates as a shielding member, a dedicated shielding mechanism and a shielding member driving section are unnecessary, resource saving can be achieved, and mass and cost can be reduced. In addition, the exclusive shield member driving software is not required, and the development cost can be reduced.

For this reason, it is suitable for resource saving, cost can be reduced, and the air conditioner which sends the airflow which air-conditioned according to the position of the occupant can be obtained at the time of use.

Moreover, according to the air conditioner of Claim 11, when the said sound sensor, a pyroelectric infrared sensor, or a thermopile is not used, it becomes difficult to show the said sound sensor, a pyroelectric infrared sensor, or a thermopile from a room.

In this way, when the sound sensor at the time of stoppage is not used, the blowing port is covered with the up-down wind direction plate, and the sound sensor is covered to make the design assimilar to the wall so that the unevenness is as noticeable as possible, Prevent dust from invading

For this reason, when the sound sensor at the time of stopping or the like is not used, it becomes a state assimilated to the atmosphere of the room, and it is possible to obtain an air conditioner having an excellent appearance when not in use, without disturbing the atmosphere of the interior.

Moreover, according to the air conditioner of Claim 12, the said up-and-down wind direction plate consists of a front part up-down wind direction plate which becomes a rear part up-down wind direction plate, and the said shielding member, and forms a transparent part and an opaque part in the said front part up-down wind direction plate. do.

Thereby, the wind direction is favorably deflected when the front upper and lower wind deflecting plates that cover the lower portion of the front face to be fused to the housing are opened. However, even if the tip portion protrudes forward, the tip portion is formed to be transparent, so that the feeling of pressure is relieved by looking in.

For this reason, the air conditioner which favorably controls a wind direction can be obtained, reducing the pressure feeling at the time of the operation of a front upper and lower wind direction plate.

Further, according to the air conditioner according to claim 13, when the driving stops, the opaque portion makes it difficult to show the sound sensor, the pyroelectric infrared sensor or the thermopile, and covers the internal display portion with the transparent portion.

As a result, when the air conditioner is stopped, the sound sensor or the infrared sensor is covered by the opaque portion of the front upper and lower wind direction plates serving as the shielding member, thereby making it possible to have a neat design without extra unevenness, and disturb the atmosphere of the interior. It doesn't happen.

In addition, the inner display part is covered with a transparent part, but when the operation stops, the front upper and lower wind direction plates rise to a vertically close angle so as to fuse to the housing. Therefore, when viewed from the bottom like a wall-mounted air conditioner, the indicator of the sensor module As long as it is not lit, the reflection on the surface of the transparent portion is strongly influenced so that the internal display portion of the rear portion becomes invisible, and as in the above, a neat design can be achieved, which does not disturb the atmosphere of the interior.

In addition, even when the front upper and lower wind direction plates are closed, when the indicator light of the sensor module is turned on, the operation indication can be checked. Therefore, in order to prevent cold wind, such as at the start of heating operation, the wind direction plate until the temperature of the heat exchanger rises. With the closed state, the operating state can be checked accurately even when the fan is in a preheating operation or not in operation.

For this reason, the air conditioner which can confirm an operation state correctly, even when the wind direction plate is closed, without disturbing the atmosphere of an interior at the time of non-use can be obtained.
