Description

Indoor unit of air conditioner equipped with sensor unit and sensor unit

The present invention relates to a sensor unit provided in an air conditioner or the like, and relates to a structure that suppresses disconnection or entanglement of communication lines.

A sensor unit including a conventional non-contact type detection sensor is provided, for example, in an indoor unit of an air conditioner. In the air conditioner, the non-contact type sensor is driven to rotate in the horizontal direction during the cooling / heating operation, and scans and detects the temperature of the human body, wall, floor, etc. existing in the room over a wide range. Thus, the sensor unit measures the temperature of each part in the room, so that the air conditioner can perform energy-saving operation without operating wastefully. As a non-contact type sensor used for the sensor unit, a pyroelectric type or thermoelectromotive force type thermal infrared detection sensor, a visible light camera, or the like is used.

In the indoor unit of the air conditioner, the sensor unit is stored in the storage unit of the indoor unit while the air conditioner is stopped in order to suppress the influence on the appearance of the indoor unit. And while the air conditioner is in operation, the sensor unit protrudes while scanning from the indoor unit to a predetermined position, and scans the sensor unit to acquire information over a wide range as described above. (For example, refer to Patent Document 1).

JP 2012-42183 A

In the sensor unit disclosed in Patent Document 1, the non-contact type sensor moves up and down along a spiral guide while driving the air conditioner while projecting from the indoor unit. The non-contact type sensor stops once when it is rotated to the end point. Next, it is rotationally driven in the reverse direction to a certain angle, and when it is rotated to the specified angle, it is rotationally driven in the reverse direction again. The object is detected by repeating the operation.

In this case, the communication line attached to the non-contact type sensor is bent by the rotation angle from the position where the non-contact type sensor is accommodated to the end point of the guide. Therefore, the angular range in which scanning can be performed by rotating the non-contact sensor may be limited depending on the arrangement of the communication lines. Further, when the communication line is bent and caught on a part near the non-contact type sensor, excessive stress is generated, the communication line is disconnected, and the non-contact type sensor cannot detect the object.

The present invention has been made to solve the above-described problems, and suppresses the catching and disconnection of an internal communication line when a non-contact type sensor capable of scanning over a wide range of angles protrudes and is stored from the sensor unit. An object of the present invention is to provide a sensor unit that can be used and an indoor unit of an air conditioner including the sensor unit.

A control device, wherein the rotation driving means is disposed on a side of a vertical movement path of the non-contact type sensor, and the non-contact type sensor is disposed on the upper surface of the non-contact type sensor. A sensor-side fixing part to which the wire is fixed, the sensor storage case being stored in the storage part in which the non-contact type sensor is stored, and a bundle in which the communication line is fixed. And the communication line extends from the sensor-side fixing portion in a direction in which the non-contact type sensor is accommodated, is fixed to the binding member, and the control device drives the vertical driving means. The position of the non-contact type sensor when the non-contact type sensor is changed from the housed state to the use state is set as an initial position, the non-contact type sensor is rotated by the rotation driving means, and the non-contact type sensor is Before storing in the sensor storage case, the rotation driving means is driven to return to the initial position, and the non-contact type sensor is brought into the storage state by the vertical driving means.

According to the sensor unit of the present invention, the non-contact type sensor can be scanned in a wide range by rotating the non-contact type sensor in the horizontal direction while the non-contact type sensor protrudes from the indoor unit. Even when the sensor rotates and the communication line is kinked, the communication line inside the unit can be gathered on the communication line storage side by rotating the non-contact sensor and returning it to the initial position. It can be stored without being caught by parts near the non-contact sensor.

FIG. The non-contact type sensor 800 protrudes from the sensor storage port 6 provided in the sensor unit 200. When the non-contact type sensor 800 protrudes from the sensor storage port 6, the air conditioner is in an operating state, and the non-contact type sensor 800 is driven to rotate horizontally to scan the room to be air-conditioned over a wide range. The temperature of a human body, a wall, a floor, etc., which are objects existing in the room, is detected.

FIG. 3 is an enlarged view of the periphery of the sensor unit 200 of the indoor unit main body 1 in FIG. 1, and shows a state in which the non-contact type sensor 800 is housed in the indoor unit main body 1. In the state where the non-contact type sensor 800 is housed in the indoor unit body 1, the air conditioner is in an operation stopped state or when the function of the non-contact type sensor 800 is stopped. When the air conditioner is stopped, the vertical wind direction plate 4 disposed at the opening of the air outlet 3 is positioned so as to cover the air outlet 3 and the left and right air direction plates 5 disposed inside the air outlet 3. Thus, the internal structure is not visible from the outside, and the influence on the external appearance of the internal structure is suppressed. Further, the front panel 10 is driven downward so as to hide the interior of the indoor unit body 1. The front panel 10 also prevents the internal structure from being seen from the outside, and suppresses the influence on the external appearance of the internal structure. Further, the non-contact type sensor 800 is also housed in the indoor unit main body 1, thereby eliminating a portion protruding from the indoor unit main body 1 so as not to affect the appearance. Further, since the non-contact sensor 800 is accommodated in the interior, the non-contact sensor 800 can be prevented from hindering the work when the indoor unit 100 is installed, and the non-contact sensor 800 can be damaged. It is preventing.

FIG. 4 is a diagram showing an AA cross section of the indoor unit main body 1 of FIG. 2, and is a diagram showing a state in which the non-contact type sensor 800 protrudes from the indoor unit 100. Hereinafter, the configuration of the sensor unit 200 will be described with reference to FIG.

The non-contact sensor 800 provided in the sensor unit 200 is housed in a cylindrical sensor case 35 and is fixed in the sensor case 35. The non-contact sensor 800 is connected to the control device 50 provided in the indoor unit 100 of the air conditioner by the communication line 43. The communication line 43 is connected to the upper surface of the non-contact type sensor 800, and is electrically connected by, for example, a connector and fixed so as not to be detached from the upper surface of the non-contact type sensor 800. Note that the communication line 43 and the non-contact sensor 800 may be fixed by soldering or the like. Although the communication line 43 is represented by one line in FIG. 4, it may be configured by bundling a plurality of lines, for example, or may be configured by combining a plurality of lines. The communication line 43 is composed of, for example, a conductive wire covered with an elastic material so that it can easily return to its original state even if it is bent.

The sensor storage case 41 is attached to the indoor unit body 1. In the sensor storage case 41, the sensor storage port 6 is opened on the outer surface of the indoor unit body 1, that is, the lower surface of the sensor storage case 41 in FIG. The sensor case 35 is configured to protrude from the sensor storage case 41 or to be stored from the sensor storage port 6. The sensor storage cover 42 is disposed above the sensor storage case 41 and covers the sensor storage case 41. The sensor storage cover 42 includes a communication line storage unit 40 that can store the communication line 43 and a rail storage unit 34 that can store the vertical drive rail 33.

The driving device 31 is arranged on the back side in FIG. 4 and is fixed to the sensor storage case 41 with the rotating shaft facing the front side. A gear 32 is coaxially fixed to the drive device 31. The gear 32 meshes with a rack portion 33 a provided on the vertical drive rail 33. The vertical drive rail 33 supports the radial direction and the thrust direction of the gear 39. The gear 39 is assembled to the sensor case 35 in which the non-contact type sensor 800 is housed, and moves in the same manner as the non-contact type sensor 800. The gear 32 and the rack portion 33a have a rack-and-pinion structure, which converts the rotation of the driving device 31 into the vertical movement of the vertical driving rail 33 and is supported by the vertical driving rail 33. Sensor 800 can be moved up and down. The drive device 31 is controlled by the control device 50. That is, the vertical movement of the non-contact sensor 800 is controlled by the control device 50. A mechanism including the drive device 31, the gear 32, the vertical drive rail 33, the gear 39, and the sensor case 35 corresponds to the vertical drive means of the present invention.

The driving device 30 has a rotating shaft directed parallel to the vertical movement direction of the non-contact type sensor 800 and is fixed downward to the sensor storage cover 42. The rotating shaft of the driving device 30 is fitted with the shaft 36. The shaft 36 is fitted coaxially with the gear 38. The gear 38 is supported by the vertical drive rail 33 so as to be rotatable in the horizontal plane of FIG. 4, the radial direction of the gear 38 is supported by the bearing portion 37b, and the axial direction of the gear 38 is supported by the support portion 33b. . The gear 39 has an axis parallel to the gear 38 and meshes with the gear 38. The gear 39 is assembled to the sensor case 35 that houses the non-contact sensor 800. The gear 38 and the gear 39 are placed on the upper and lower drive rails 33 in a rotatable state, and a rail cover 37 is covered from above so as to move together with the upper and lower drive rails 33 in the vertical direction. . With the configuration as described above, the driving device 30 rotates the shaft 36 and the gear 38 fitted to the shaft 36 also rotates the same. The rotation of the driving device 30 is transmitted from the shaft 36 to the gear 39 via the gear 38, whereby the non-contact type sensor 800 is rotated in the horizontal direction. The rotation direction of the shaft 36, the gear 38, and the gear 39 is set to rotate in the horizontal direction, that is, around an axis parallel to the vertical movement direction of the non-contact sensor 800. The drive device 30 is controlled by the control device 50. That is, the rotation of the non-contact sensor 800 is controlled by the control device 50. A mechanism for rotating the non-contact type sensor 800 including the drive device 30, the shaft 36, the gear 38, the gear 39, the vertical drive rail 33, and the rail cover 37 corresponds to the rotational drive means of the present invention.

A protrusion 39 a is provided on the upper surface of the gear 39. The rail cover 37 is provided with a stopper 37a on the same circumference on which the protrusion 39a of the gear 39 rotates. The stopper 37a limits the rotation of the gear 39 by coming into contact with the protrusion 39a so that the non-contact sensor 800 does not rotate more than a certain amount. The gear 39 and the rail cover 37 are provided with holes so that the communication line 43 fixed to the upper surface of the non-contact sensor 800 can be drawn upward.

(Function of the indoor unit 100 of the air conditioner)
Here, a basic function of the indoor unit 100 of the air conditioner including the non-contact type sensor 800 will be described.

As shown in FIG. 1, an indoor unit 100 of an air conditioner is configured to suck indoor air from a suction port 2 arranged on the upper surface of a box-shaped indoor unit body 1 and blow out air from a blower port 3. A blower (not shown) is provided inside the indoor unit body 1. Also, a heat exchanger (not shown) for exchanging heat between the air and the refrigerant is provided inside, and this heat exchanger is connected to a compressor or the like mounted on an outdoor unit (not shown) to be connected to a refrigeration cycle. Is forming.

Also, the lower surface of the indoor unit main body 1 is provided with an up / down air direction plate 4a and an up / down air direction plate 4b for controlling the up / down direction of the blown airflow. Further, the outlet 3 is provided with a left and right wind direction plate 5 to control the left and right direction of the blown airflow. As described above, air that has undergone heat exchange over a wide range in the room is blown out to perform air conditioning.

(Operation of sensor unit 200)
FIG. 5 is a diagram when the non-contact sensor 800 of FIG. 4 stops in a horizontal direction. FIG. 6 is a view showing a CC section of the indoor unit main body of FIG. 3, and is a view showing a state where the non-contact type sensor is housed in the indoor unit main body. FIG. 7 is a diagram showing a BB cross section of FIG. 2, and is a diagram showing a state in which the non-contact type sensor 800 protrudes from the indoor unit 100. Next, operations of the sensor unit 200 and the non-contact sensor 800 according to the first embodiment will be described with reference to FIGS. 4, 5, 6, and 7.

As shown in FIG. 6, the non-contact type sensor 800 is housed in the rail housing case with the vertical drive rail 33 raised upward. When the air conditioner starts operation, the non-contact sensor 800 starts to project from the sensor storage case 41. First, a signal for generating power in the clockwise direction in FIG. 6 is transmitted from the control device 50 to the drive device 31. When the drive device 31 rotates clockwise in FIG. 6, the rotational power is transmitted to the gear 32 fixed to the rotation shaft of the drive device 31, and the gear 32 rotates in the same direction as the rotation shaft of the drive device 31. Then, the power to move downward is transmitted to the vertical drive rail 33 engaged with the gear 32, and the vertical drive rail 33 moves downward.

As the vertical drive rail 33 moves downward, the gear 38 and the gear 39 held by the vertical drive rail 33 and the rail cover 37, and the sensor case 35 fixed to the gear 39 move downward and contactless. The mold sensor 800 protrudes from the sensor storage case 41. With the above operation, the sensor unit 200 is in a state in which the non-contact sensor 800 is projected as shown in FIG. The position of the non-contact type sensor 800 when the non-contact type sensor 800 is changed from the housed state to the use state is set as the initial position of the non-contact type sensor 800. In the initial position, the communication line 43 connected to the non-contact type sensor 800 is not kinked, and the communication line 43 exits from the upper surface of the non-contact type sensor 800 and is folded upward as shown in FIG. Thus, it is drawn out toward the binding member 60.

Next, a rotation signal is transmitted from the control device 50 to the drive device 30. At this time, the rotation signal may be either clockwise or counterclockwise. When the drive device 30 performs a rotation operation, the rotational power is transmitted to the shaft 36 attached to the drive device 30, and the drive device 30 and the shaft 36 rotate in the same direction. When the shaft 36 rotates, the gear 38 attached to the shaft 36 rotates in the same direction. As the gear 38 rotates, rotational power is transmitted to the meshing gear 39, and the sensor case 35 fixed to the gear 39 also rotates at the same time, whereby the non-contact sensor 800 rotates. As described above, the non-contact sensor 800 can scan the detection target in the room over a wide range.

The communication line 43 fixed to the sensor-side fixing portion 43b on the upper surface of the non-contact type sensor 800 is drawn upward and folded to provide a binding member provided on the side of the space where the non-contact type sensor 800 moves up and down. 60 is fixed. The binding member 60 is provided in the middle of the plurality of communication lines 43 that connect the control device 50 and the non-contact type sensor 800, and is fixed to the sensor storage case 41. The binding member 60 fixes all directions including the rotation direction of the communication line 43. The length from the sensor side fixing portion 43b to the binding member 60 is at least longer than the sum of the vertical movement distance of the non-contact sensor 800 and the horizontal distance from the sensor side fixing portion 43b to the binding member 60. There is a need.

Rotating the non-contact type sensor 800 can detect the detection target in the room where the indoor unit 100 is installed up to 360 degrees. However, if the non-contact sensor 800 continues to rotate in the same direction, the communication line 43 is kinked by the rotation, and stress is generated in the communication line 43. Therefore, due to the contact between the protrusion 39a and the stopper 37a shown in FIG. 4, the rotation of the gear 39 is stopped at a certain position, and the rotation of the non-contact sensor 800 is also stopped. When the rotation stop of the non-contact sensor 800 is detected, a signal for rotating in the reverse direction is transmitted from the control device 50 to the drive device 30. When the protrusion 39a rotated in the reverse direction comes into contact with the stopper 37a from the reverse direction again, the rotation of the gear 39 is stopped and the rotation of the non-contact sensor 800 is also stopped. When the rotation stop of the non-contact type sensor 800 is detected, a signal for rotating again in the reverse direction is transmitted from the control device 50 to the driving device 30. By repeating this operation, the non-contact sensor 800 can detect the air-conditioning object while scanning the air-conditioning target area in the room in the horizontal direction.

(Positioning operation of non-contact type sensor 800)
Further, the projection 39 a of the gear 39 and the stopper 37 a function as positioning of the non-contact sensor 800. In order to prevent the angle range detected by the non-contact sensor 800 from deviating from the target angle range, the position where the protrusion 39a and the stopper 37a are in contact is set as the reference position in the rotation direction of the non-contact sensor 800, and the rotation is performed. The position can be initialized. That is, in the state where the non-contact type sensor 800 described above is first projected, the control device 50 rotates either clockwise or counterclockwise. At that time, the protrusion 39a and the stopper 37a are moved. When the contact is made and the non-contact sensor 800 stops, the rotational position is initialized. The positioning operation is performed before the non-contact sensor 800 protrudes from the sensor storage case 41 and detects an air-conditioning object in the room or after the air conditioner stops operating.

(Operation for suppressing the pinching of the communication line 43)
When the air conditioner stops operation, the non-contact sensor 800 stops detecting the object. The non-contact type sensor 800 can be stored in the sensor storage case 41 by the drive device 31 rotating in the counterclockwise direction and the vertical drive rail 33 moving upward. However, as shown in FIG. 5, when the non-contact sensor 800 stops at a certain horizontal rotation angle, the communication line 43 fixed on the upper surface of the non-contact sensor 800 is kinked, and the non-contact sensor In some cases, the sensor 800 may be shifted to a position shifted from the communication line storage unit 40 formed in the upper part of the part in which the sensor 800 is stored. If the vertical drive rail 33 moves in the upward direction with the communication line 43 being displaced from the communication line storage unit 40, the communication line 43 may not fit in the communication line storage unit 40 and may be caught by other components. For example, in FIG. 6, the sensor housing cover 42 may be caught in a space 70 between the partition portion 42 a and the rail cover 37.

Therefore, the control device 50 rotates the non-contact type sensor 800 before storing the non-contact type sensor 800 in the sensor storage case 41. Then, the non-contact sensor 800 is rotated so as to return to the initial position, that is, the state immediately after the non-contact sensor 800 is protruded from the sensor storage case 41. The bundling member 60 fixed to the sensor storage case 41 serves as a fulcrum of the communication line 43, and the communication side 43 is rotated by the rotation of the sensor side fixing part 43b which is a fixing part of the non-contact type sensor 800 side of the communication line 43. The vertex 43a where the communication line 43 is folded is twisted as the center of rotation. However, since the sensor-side fixing portion of the communication line 43 is also returned to the initial position when the non-contact sensor 800 is returned to the initial position, the communication line 43 is not kinked. The communication line 43 having elasticity returns to the shape of the line at the initial position when the kinks are eliminated, and returns to the position immediately below the communication line storage unit 40 as shown in FIG.

As described above, the non-contact type sensor 800 is rotated and returned to the initial position, and the communication line 43 is placed in the direction of the communication line storage unit 40, and then the vertical drive rail 33 moves the non-contact type sensor 800 upward. Move. As a result, as shown in FIG. 6, the communication line 43 is accommodated in the communication line accommodation unit 40 without being caught by other components. As a result, the communication line 43 can be sufficiently secured without being caught by peripheral components.

In the above description, before the non-contact type sensor 800 is stored in the sensor storage case 41 provided in the indoor unit 100, the non-contact type sensor 800 is rotated so as to return to the state immediately after being projected from the sensor storage case 41. Thus, the communication line 43 is accommodated in the communication line storage unit 40. However, the initial position of the non-contact sensor may be, for example, the contact position (positioning position) between the stopper 37a and the protrusion 39a. Alternatively, a position at a predetermined angle from the contact position (positioning position) between the stopper 37a and the protrusion 39a may be set as the initial position.

The timing for positioning the non-contact type sensor 800 is performed when the operation is started, when the operation is stopped, or both. For example, when the operation is stopped, the rotation position is initialized by rotating the non-contact type sensor 800 in a predetermined direction to the positioning position, and the state of the communication line 43 can be returned to the initial position. Therefore, the storing operation of the non-contact type sensor 800 can be performed at the same time. By moving the vertical drive rail 33 upward while the non-contact type sensor 800 is in the positioning position, the non-contact type sensor 800 is stored without rotating in the horizontal direction. The communication line 43 can be stored in the communication line storage unit 40 without causing a shift in the angle range and without being sandwiched between other components.

In the positioning operation of the non-contact type sensor 800, the communication line 43 is accommodated in the communication line storage unit 40, the vertical drive rail 33 moves upward, and the non-contact type sensor 800 is stored in the sensor storage case 41. You may carry out after. In a state where the non-contact type sensor 800 is stored, the communication line 43 is stored in the communication line storage unit 40, so that the positioning operation of the non-contact type sensor 800 can be performed without being caught by peripheral components. In addition, since the communication line 43 is sufficiently long between the bundling member 60 and the non-contact type sensor 800, even if the non-contact type sensor 800 rotates in the horizontal direction, the amount of bending can be reduced. The generated stress is small. However, when the non-contact type sensor 800 is taken in and out of the sensor storage case 41, the non-contact type sensor 800 is inserted at the initial position, that is, the position where the communication line 43 is not kinked. It is necessary to move up and down.

Also, a mode in which the non-contact type sensor 800 is not used can be set in order to suppress the influence on the appearance of the non-contact type sensor 800 while the user of the air conditioning apparatus is in operation. The setting can be performed by an operation using a remote controller.

For example, when the air conditioning apparatus is operated with the non-contact type sensor 800 in operation and the user transmits a setting not to use the non-contact type sensor 800 by the remote controller, even if the air conditioning apparatus is in operation. The non-contact type sensor 800 is rotated to the initial position so that the communication line 43 can be accommodated in the communication line storage unit 40, and then the vertical movable rail is moved upward so that the non-contact type sensor 800 is stored. . Further, if the non-contact sensor 800 is set not to be used before the operation is started, the non-contact sensor can be operated while being stored without protruding from the sensor storage case 41 even after the operation is started. it can.

As described above, although the first embodiment has been described as the sensor unit disposed in the indoor unit of the air conditioner, the present invention is not limited to this. For example, even in a floor-mounted dehumidifier or humidifier, it is possible to install the sensor unit so that the non-contact type sensor protrudes upward, with the sensor unit mounted in the opposite direction to the mounting direction of the indoor unit of the air conditioner. is there. By mounting the sensor unit 200 of the first embodiment, the communication line 43 can be prevented from being caught and caught, and the reliability as a product can be ensured. In addition, since the non-contact type sensor 800 can be housed inside the dehumidifier or humidifier, there is no protrusion on the product surface, so there is little influence on the appearance. In addition, by mounting the sensor unit 200 on a dehumidifier or humidifier, infrared rays on the surface of an indoor object are detected (for example, a human body), and when no object is present, humidification and dehumidification operations are suppressed, and power consumption is reduced. Can be suppressed.

(effect)
The sensor unit 200 according to Embodiment 1 is arranged in a non-contact type sensor 800 that can detect the temperature of an object existing in the surroundings, a sensor storage case 41 that stores the non-contact type sensor 800, and the sensor storage case 41. Rotation drive means for rotating the non-contact type sensor 800 and a sensor storage case 41 which is disposed inside the sensor storage case 41, moves the non-contact type sensor in the vertical direction, and stores the non-contact type sensor 800 in the sensor storage case 41. The vertical drive means for putting the contact sensor 800 out of the sensor storage case 41, the communication line 43 for transmitting the signal detected by the non-contact sensor 800, and the movement of the rotary drive means and the vertical drive means are controlled. And a control device 50. The rotation driving means is disposed on the side of the vertical movement path of the non-contact type sensor 800. The non-contact sensor 800 has a sensor side fixing portion 43b to which the communication line 43 is fixed on the upper surface. The sensor storage case 41 includes a storage unit that stores the non-contact type sensor 800 and a binding member 60 that is disposed on the side of the storage unit and fixes the communication line. The communication line 43 extends from the sensor side fixing portion 43b in a direction in which the non-contact type sensor 800 is accommodated, and is fixed to the binding member 60. The control device 50 drives the vertical driving means to set the position of the non-contact sensor when the non-contact sensor 800 is changed from the housed state to the use state as an initial position, and the non-contact sensor 800 is rotationally driven by the rotational drive means. Before the non-contact type sensor 800 is stored in the sensor storage case 41, the rotation driving unit is driven to return to the initial position, and the non-contact type sensor 800 is stored in the sensor storage case 41 by the vertical driving unit. By adopting such a configuration, the non-contact sensor 800 can be scanned in a wide range by rotating in the horizontal direction while protruding from the indoor unit 100. Further, even when the non-contact sensor 800 is rotated by scanning and the communication line 43 is kinked, the communication line 43 in the sensor unit 200 is communicated by rotating the non-contact sensor 800 and returning it to the initial position. They can be grouped on the line storage unit 40 side, and can be stored without being caught by components near the sensor during storage.

In the sensor unit 200 of the first embodiment, the rotation driving means includes a rotation stopper that restricts the rotation of the non-contact sensor 800. The rotation stopper corresponds to the protrusion 39a of the gear 39 and the stopper 37a. By adopting such a configuration, it is possible to position the non-contact type sensor 800 in the rotational direction, and it is possible to correct a deviation of the rotation angle when scanning is performed due to the rotation of the non-contact type sensor 800. The detection by the non-contact type sensor 800 can be performed well. In addition, since the displacement of the initial position of the non-contact type sensor 800 can be corrected by the positioning operation, the communication line 43 can be operated without being caught by peripheral components even when the non-contact type sensor 800 is moved up and down. .

Further, in the sensor unit 200 of the first embodiment, the control device 50 positions the non-contact sensor 800 with the position where the rotation of the non-contact sensor 800 is stopped by the rotation stopper as a reference position. With such a configuration, the non-contact sensor 800 can be positioned in the rotational direction, and the detection accuracy of the non-contact sensor 800 can be ensured and the communication line 43 can be prevented from being caught as described above.

In the sensor unit 200 of the first embodiment, the initial position is a state in which the rotation of the non-contact sensor 800 is stopped by the rotation stopper. With such a configuration, the non-contact sensor 800 can be positioned in the rotational direction, and the detection accuracy of the non-contact sensor 800 can be ensured and the communication line 43 can be prevented from being caught as described above. In addition, since the communication line 43 can be returned to the initial position before storage and the positioning of the non-contact type sensor 800 can be performed at the same time, the operation of the non-contact type sensor 800 can be minimized and the positioning and the communication line 43 can be prevented from being caught. Can do.

In addition, by using the indoor unit 100 of the air conditioner equipped with the sensor unit 200 of the first embodiment, the non-contact sensor 800 ensures the accuracy of detection of human bodies, walls, floors, etc. existing in the room, A highly reliable indoor unit 100 of an air conditioner in which the internal communication line 43 is not caught is obtained.
