At the same time, the first electrical connection portion 51 ′ and the second electrical connection portion 52 ′ are engaged. By using such a structure, the joint between the convex portion 38 and the concave portion 28 restricts the relative position between the scent generating member 20 ′ and the elevating member 30 ′, and further secures the connection by the electric connector 50 ′. . Further, since the convex portion 38 and the concave portion 28 serve to protect the electrical connection portions 51 ′ and 52 ′ housed therein, the electrical connection portions 51 ′ and 52 ′ are subjected to an impact. It becomes difficult to be damaged.

FIG. 8 shows an electrical connector 50 ″ according to a further embodiment, which is different from the installation positions of the previous

electrical connectors

Portions 51 ″ and 52 ″ are provided on the inner wall of the scent generating member 20 ″ and the casing 10 ″, respectively. Then, when the scent generating member enters the operating position, since the two electrical connection portions 51 ″ and 52 ″ are joined and electrically connected, the scent generating member is connected to the air treatment device by the electrical connector. It comes to be in electrical communication with other members. The specific position and structure of the electrical connector 50 ″ can be adjusted by the internal structure and arrangement of the air treatment device.

In the air treatment device and its control method, a detection means may be further provided. The detection means detects the state of the scent generating member 20, is connected to the control means, and transmits the detection result to the control means, thereby controlling the means and members in the air treatment device 1.

According to one embodiment, the detection means includes a liquid level sensor for detecting the remaining amount in the fragrance bottle, and when it is detected that the remaining amount of the fragrance in the fragrance bottle has reached a predetermined lower limit, This result is transmitted to the control means, and the raising and lowering of the scent generating member 20 is controlled based on the detection result, so that the accuracy of the control is increased.

Further, the decorative panel 12 is provided on the suspended ceiling at a position corresponding to the opening, and the decorative panel 12 includes a cover plate 60 that can be opened and closed. As shown in FIG. The open / close state of the cover plate 60 can be detected. For example, the detection means acquires an open / closed state signal of the cover plate 60 via a cover plate-limit switch, and the detection means transmits the state signal to the control means. When the state signal provided from the detection means indicates that the cover plate 60 is in the closed position (closed position) or not fully opened, the control means prohibits the operation by the elevating member 30. To do. When the state signal provided from the detection means indicates that the cover plate 60 is in the open position, the control means allows operation by the elevating member 30.

Also preferably, the detecting means may further include a scent generating member-limit switch for detecting whether or not the scent generating member 20 is in an operating position in the housing 10. The limit switch 43 may be attached to the scent generating member 20, may be attached to the elevating member 30, and may be further attached to the housing 10. When the scent generating member 20 is in the operating position, the scent generating member-limit switch is turned off, and when the scent generating member 20 leaves the operating position, the scent generating member-limit switch is turned on. Yes. Preferably, the limit switch may be integrated with the electrical connection 50. Then, the detection means can detect the connection state by the electrical connection part 50 correspondingly. Therefore, if the electrical connection unit 50 is disconnected during use, the detection unit can transmit a failure signal to the control unit in real time.

When it is determined by the control means that the scent generating member 20 needs to be taken out (for example, when the remaining amount of the scent is insufficient), the detecting means determines the position of the scent generating member 20 based on the detection result by the limit switch. When the state signal is transmitted to the control means and the scent generating member-limit switch is turned off, the control means controls to open the cover plate 60, and when the scent generating member-limit switch is turned on. The control means prohibits the cover plate 60 from opening. If it does so, when opening the cover board 60, the scent generation | occurrence | production member 20 will fall unexpectedly, and it can prevent giving a damage to a user.

On the other hand, before the control means controls the opening / closing of the cover plate or the raising / lowering of the elevating member, the detection means can detect the connection state between the two electrical connection parts, and the control means can detect the detection by the detection means. Based on the result, it is determined whether the scent generating member 20 can be moved up and down or the lid plate 60 can be opened and closed.

Specifically, the control means in the air treatment apparatus is configured to issue a command indicating that the scent generating member 20 needs to be moved to the replacement position (for example, a command transmitted by the user to the control means using a remote controller, wired, smart terminal, or the like). ) Or a command of a preset program in the apparatus (for example, when the remaining amount of the fragrance in the scent generating member reaches a predetermined lower limit value, the command of the program set in advance is controlled by the control means. The scent generating member 20 is moved to the replacement position, and the detecting means moves the first electrical connection portion and the second electrical connection. When the electrical connection state between the first electrical connection unit and the second electrical connection unit exists, the control means detects the state of the electrical connection with the unit. To open In addition, the elevating member is controlled so as to move the scent generating member 20 to the replacement position, while the detection result indicates that the electrical connection between the first electrical connection portion and the second electrical connection portion is interrupted. When it is done, the control means controls so as to hold the lid plate 60 closed. In a normal state, first, the cover plate 60 may be opened to a predetermined position, and the wrapping cloth 33 may be rotated by the electric motor 32 of the elevating member 30, and the scent generating member 20 may be moved to the replacement position. .

Alternatively, the scent generating member 20 may be moved downward by the elevating member 30 at the same time when the cover plate 60 is opened. Of course, the control means controls the opening speed of the cover plate 60 and the descending speed of the scent generating member 20 so that the cover plate 60 does not interfere with the scent generating member 20 descending and passing through the decorative panel 12. Secured.

Moreover, in order to avoid that the scent generating member 20 unexpectedly falls from the opening and damages a person, the air processing device detects the state of the scent generating member 20 using various sensor devices. You can also The detection means may include a displacement sensor that detects the position of the scent generating member 20. The displacement sensor is arranged to detect whether or not the scent generating member 20 is separated from the operating position. When the displacement sensor detects that the scent generating member 20 is separated from the operating position, It is determined that the electrical connection between the first electrical connection portion and the second electrical connection portion is interrupted, and the control means controls the lid plate 60 to be held closed. Specifically, the displacement sensor may be an infrared sensor or a raster sensor.

The sensor is attached to the frame of the air treatment device. Specifically, the height position where the sensor is attached may be near the bottom of the frame 21 of the scent generating member 20. When the scent generating member 20 moves away from the operating position, the light from the infrared sensor or the raster sensor is blocked, and the sensor is triggered, whereby the first electrical connection portion and the second electrical connection portion It can be determined that the electrical connection to is interrupted.
