Technical Field

[0001] The present invention relates to a sensor assembly and an air-conditioning system including the sensor assembly. Background Art

[0002] With the development of the economy, people's living standards have been greatly improved, and various valuable items such as high-end computers and mobile phones have entered thousands of households. Some of these items are easy to carry and thus attract the attention of lawbreakers. Especially when people travel, go on business trips, etc., leaving their homes unattended for a long time, thefts are more likely to occur.

[0003] In view of the above situation, for example, it is possible to consider setting a household protection assembly with a human detection function at the ceiling of a room.

[0004] However, when setting the above household protection assembly at the ceiling of a room, the detection range of the household protection assembly may be reduced due to being blocked by indoor walls, etc., and the household protection assembly may affect the overall aesthetics of the room. Summary of the Invention

And, as Figure 7 shown, when viewed in a direction perpendicular to the stacking direction of the panel 310 and the seat portion 320, the outer peripheral portion of the seat portion 320 is in a stepped shape having a step portion TJ1 (in the illustrated example, the entire outer peripheral portion of the seat portion 320 is in a stepped shape having a step portion TJ1, but it is not limited thereto, and it may be only a part of the outer peripheral portion of the seat portion 320 that is in a stepped shape having a step portion TJ1).

[0140] In addition, the panel 310 and the seat portion 320 are connected to each other by a snap-fit structure. Specifically, as Figure 8 shown, the seat portion 320 has a main body portion 321 and a flange portion 322, the main body portion 321 is in the shape of an open box (substantially rectangular when viewed in the Z direction in the figure, but not limited thereto), the opening of the main body portion 321 faces the panel 310 side (the Z2 direction side in the figure), and the flange portion 322 is provided at the edge of the opening of the main body portion 321 in a manner that forms a step together with the main body portion 321 (extending from the opening edge of the main body portion 321 toward the outer peripheral side), as Figure 10As shown, the panel 310 is in the shape of an open box (roughly rectangular when viewed along the Z direction in the figure, but not limited thereto), and the opening of the panel 310 faces the side of the seat portion 320 (the side in the Z1 direction in the figure). The seat portion 320 and the panel 310 are connected by engaging the outer peripheral edge 322a of the flange portion 322 with the peripheral edge 311a of the opening of the panel 310 with their openings facing each other. Moreover, the seat portion 320 is provided with a third fixing structure MT3 fixedly connected to the ceiling CL. Specifically, the flange portion 322 of the seat portion 320 is provided with a third fixing structure MT3 fixedly connected to the ceiling CL, and this third fixing structure MT3 can be a screw fixing structure and / or a spring buckle fixing structure (in the illustrated example, it includes two gourd holes located at the diagonal positions of the seat portion 320 when viewed from above and capable of cooperating with screws. During installation, for example, in a state where the main body portion 321 of the seat portion 320 is inserted into the opening of the ceiling CL and the flange portion 322 of the seat portion 320 abuts against the peripheral edge of the opening of the ceiling CL, screws are passed through the above gourd holes and screwed into the ceiling CL to fix the seat portion 320 to the ceiling CL, and then the panel 310 is engaged with the seat portion 320). Also, in the seat portion 320, the top of the main body portion 321 has a wire passing hole WH1 into which the following seal 344 can be inserted.

[0141] In addition, as Figure 2A shown, the inclined surface 3121 is arranged offset from the center of the panel 310. Specifically, the inclined surface 3121 is arranged close to one edge of the panel 310 (in the illustrated example, it is the edge 311a1 on the X1 direction side of the main body 311 of the panel 310d), and the part of the inclined surface 3121 close to the above one edge is connected to the main body 311 of the panel 310. Also, as Figure 2A and Figure 2B shown, the inclined surface 3121 is a concave surface, and the angle β at which the inclined surface 3121 is inclined with respect to the reference plane PLR perpendicular to the stacking direction of the panel 310 and the seat portion 320, that is, the X1 direction side and the Z1 direction side endpoints of the arc segment formed by the inclined surface 3121 in the perspectives of Figure 2A and Figure 2B (refer to the point PT1 in Figure 2B and Figure 5 ) and the X2 direction side and the Z2 direction side endpoints of the arc segment formed by the inclined surface 3121 in the perspectives of Figure 2B and Figure 5 (refer to the point PT2 in Figure 2B and Figure 5 ) forms an angle within the range of 15° to 30° with respect to the reference plane PLR. Also, preferably, the angle β1 at which the area where the through hole TH is located in the inclined surface 3121 is inclined with respect to the reference plane PLR, that is, the X1 direction side and the Z1 direction side endpoints of the arc segment formed by the area where the through hole TH is located in the inclined surface 3121 in the perspectives of Figure 2A and Figure 2B (refer to the points in Figure 2B andFigure 5 The point PT3) in it and the endpoints on the X2-direction side and the Z2-direction side (refer to Figure 2B and Figure 5 The angle formed by the line connecting the point PT4) in it with respect to the reference plane PLR is in the range of 15° to 20°, and more preferably 17°.

[0142] In addition, as Figure 2A and Figure 2B shown, the side surface 3122 on the side of the protruding portion 312 opposite to the inclined surface 3121 (the X2-direction side in the figure) is also an inclined surface and is a concave surface. Thus, the aesthetic appearance can be improved. And when there are modules such as an LED assembly and an illuminance sensor near the side surface 3122 (for example, on the X2-direction side in the figure), it helps to prevent the operation of the modules from being affected by the side surface 3122 (for example, the irradiation area of the LED assembly and the side surface 3122 blocking the illuminance sensor).

[0143] In addition, the human detection component 331 detects the presence of a person by, for example, sensing heat sources or image recognition. In the human detection component 331, the human detection sensor 3311 is constituted by, for example, an infrared sensor and has a conical detection range with the human detection sensor 3311 as the vertex and the apex angle being α (for example, 131.7°) as Figure 2A shown, and the human detection sensor 3311 is arranged such that the center line of its detection range is inclined with respect to the reference plane PLR. And as Figure 4 and Figure 10As shown, the human detection component 331 includes a first circuit board 3312 for installing the human detection sensor 3311. Moreover, on one side of the seat portion 320 of the panel 310, there is provided a first circuit board mounting portion 3111 including a first fixing structure MT1. The first circuit board 3312 is disposed on the first circuit board mounting portion 3111 in a manner inclined with respect to the ceiling CL through the first fixing structure MT1. And the first fixing structure MT1 has a plurality of abutting portions that abut against the first circuit board 3312 to clamp the first circuit board 3312 at least from both sides (in the illustrated example, it includes a pair of short strip-shaped first abutting portions AB1 that abut against the first circuit board 3312 from both sides in the Y direction, a pair of long strip-shaped second abutting portions AB2 that are on the X2 direction side of this pair of short strip-shaped abutting portions and abut against the first circuit board 3312 from both sides in the Y direction, two small protrusion-shaped third abutting portions AB3 that abut against the first circuit board 3312 from the X1 direction side and are adjacent in the Y direction, and a fourth abutting portion AB4 that abuts against the first circuit board 3312 from the X2 direction side. Among them, the portion where the first abutting portion AB1 contacts the first circuit board 3312 is closer to the Z1 direction side than the portion where the third abutting portion AB3 contacts the first circuit board 3312, the portion where the second abutting portion AB2 contacts the first circuit board 3312 is closer to the Z1 direction side than the portion where the first abutting portion AB1 contacts the first circuit board 3312, and the portion where the fourth abutting portion AB4 contacts the first circuit board 3312 is closer to the Z1 direction side than the portion where the second abutting portion AB2 contacts the first circuit board 3312).

[0144] In addition, as Figure 4 and Figure 10 shown, the electrical component includes a second circuit board 332 for control. The second circuit board 332 is electrically connected to the human detection component 331. Specifically, as Figure 4 shown, the second circuit board 332 is electrically connected to the first circuit board 3312 of the human detection component 331 via a wire. The second circuit board 332 is also electrically connected to the power circuit board 341 of the following power supply component 340 via a wire, and further electrically connected to the indoor unit 100. And, as Figure 4 and Figure 10 shown, on one side of the seat portion 320 of the panel 310, there is provided a second circuit board mounting portion 3112 including a second fixing structure MT2. The second circuit board 332 is disposed on the second circuit board mounting portion 3112 in a manner parallel to the reference plane PLR (i.e., in a manner parallel to the ceiling CL) through the second fixing structure MT2 (in the illustrated example, the second fixing structure MT2 has protrusions that support a plurality of corners of the second circuit board 332 and fixing screws SC1 that fix the plurality of corners of the second circuit board 332 to the protrusions). And the second circuit board 332 is arranged side by side with the first circuit board 3312 (in the illustrated example, it is arranged side by side along the X direction).

[0145] In addition, as Figure 10 shown, a wire slot portion is also provided on the side of the panel 310 facing the inside of the ceiling (in the illustrated example, a first wire slot portion SN1, a second wire slot portion SN2, and a third wire slot portion SN3 are provided on the Y2 direction side of the first circuit board 3312 and the second circuit board 332 in a manner arranged substantially along the X direction), as Figure 4 shown, during assembly, the wire electrically connecting the first circuit board 3312 and the second circuit board 332 can be snapped into the wire slot portion for fixation.

[0146] In addition, as Figure 3 and Figure 9 shown, the sensor assembly 300 further includes a power supply assembly 340, and the power supply assembly 340 is provided on the side of the seat portion 320 opposite to the panel 310. Moreover, the power supply assembly 340 is generally in a substantially rectangular parallelepiped shape and includes a power supply circuit board 341, a power supply circuit board fixing sheet metal 342, and a power supply circuit board fixing cover 343. Among them, the power supply circuit board 341 is fixed to the power supply circuit board fixing sheet metal 342 by fixing screws SC2, for example, and is electrically connected to the second circuit board 332 to supply the power supplied from the indoor unit 100 via the wire 200 to the second circuit board 332. Components such as a transformer are provided on the power supply circuit board 341. The power supply circuit board fixing sheet metal 342 (substantially rectangular when viewed along the Z direction in the figure, but not limited thereto) is fixed to the seat portion 320 by a grounding screw SC3, for example. The power supply circuit board fixing cover 343 (substantially rectangular when viewed along the Z direction in the figure, but not limited thereto) is provided on the power supply circuit board fixing sheet metal 342 so as to cover the power supply circuit board 341 and is fixed to the power supply circuit board fixing sheet metal 342 by fixing screws SC4, for example. And, a wire passing hole WH2 is formed in the power supply circuit board fixing sheet metal 342, and a seal 344 made of rubber or the like is embedded in the wire passing hole WH2. A through hole for the wire to pass through is provided in the center of the seal 344. And, a wire passing hole (provided in the wall portion on the Y2 direction side of the rectangular parallelepiped-shaped power supply circuit board fixing cover 343 in the illustrated example, but not limited thereto) is formed in the power supply circuit board fixing cover 343, and a seal 345 made of rubber or the like is embedded in the wire passing hole. The wire 200 is led out from the inside of the power supply circuit board fixing cover 343 through the through hole in the center of the seal 345 and is connected to the indoor unit 100. And, as Figure 7As shown, the main body 321 of the seat portion 320 extends toward the outer peripheral side with respect to the power supply assembly 340, thereby forming a stepped portion TJ2 between the main body 321 of the seat portion 320 and the power supply assembly 340. That is to say, the size of the power supply assembly 340 in the direction perpendicular to the stacking direction of the panel 310 and the seat portion 320 is smaller than that of the main body 321 of the seat portion 320. Thus, when the sensor assembly 300 is installed on the ceiling CL, the power supply assembly 340 can be conveniently installed in the opening of the ceiling CL.

[0147] In addition, the electrical components further include one or more modules among an LED assembly, an illuminance sensor, and a buzzer, so as to warn an intruder by lighting up and beeping when the sensor assembly 300 is used as an alarm, and the panel 310 has an opening portion corresponding to the module. Specifically, the above-mentioned module is disposed in the module setting area 3113 adjacent to the protruding portion 312 of the panel 310 and having the above-mentioned opening portion. The side surface 3122 of the protruding portion 312 adjacent to the module setting area 3113 is a concave surface as described above, and, as Figure 4 、 Figure 5 and Figure 7 shown, a light-transmitting plate 350 is provided on the panel 310 to cover the above one or more modules (in the illustrated example, the light-transmitting plate 350 has a flat portion 351 and a folding portion 352, where the flat portion 351 overlaps the module setting area 3113 of the panel 310, and the folding portion 352 covers the side surface 3122 of the protruding portion 312, but it is not limited thereto, and there may be no folding portion 352). And, the above-mentioned module is electrically connected to the second circuit board 332, for example.

[0148] (Operation of the air-conditioning system)

[0149] In the present embodiment, the air-conditioning system 1 has an anti-theft mode and a night light mode. In the anti-theft mode, when the sensor assembly 300 detects a person, the control unit causes at least one of the LED assembly and the buzzer to operate. In the night light mode, when the sensor assembly 300 detects a person, the control unit causes the LED assembly to operate. And, in the anti-theft mode, when the sensor assembly 300 detects a person, the control unit also sends the information indicating that the sensor assembly 300 has detected a person to the mobile terminal.

[0150] In addition, the air conditioning system 1 also has an automatic startup mode and a human detection air flow control mode. In the automatic startup mode, when the temperature in the room reaches the set temperature (e.g., 28 degrees or lower than 10 degrees) and the sensor assembly 300 detects a person, the control unit turns on the air conditioner. The human detection air flow control mode includes an air avoidance mode and an air blowing mode. In the air avoidance mode, when the sensor assembly 300 detects a person, the control unit causes the air blown out by the indoor unit 100 to avoid the position where the person is located. On the other hand, in the air blowing mode, when the sensor assembly 300 detects a person, the control unit causes the air blown out by the indoor unit to face the position where the person is located.

[0151] (Main effects of this embodiment)

[0152] In the air conditioning system 1 according to this embodiment, the panel 310 of the sensor assembly 300 has a protruding portion 312 that protrudes from the main body 311 of the panel 310 toward the side opposite to the seat portion 320. The protruding portion 312 has an inclined surface 3121, and the inclined surface 3121 is inclined with respect to a reference plane PLR perpendicular to the stacking direction of the panel 310 and the seat portion 320, and has a through hole TH for exposing the human detection sensor 3311. Therefore, even if the sensor assembly 300 is arranged at a position on the ceiling CL near the room wall WL in such a way that the stacking direction of the panel 310 and the seat portion 320 is perpendicular to the ceiling CL (refer to Figure 2A ), as long as the human detection sensor 3311 exposed from the through hole TH of the inclined surface 3121 faces away from the wall WL, a large detection range can be ensured. Moreover, the seat portion 320 houses a part of the electrical components in the stacking direction of the panel 310 and the seat portion 320, and at least a part is buried inside the ceiling CL. Therefore, the part of the sensor assembly 300 protruding from the ceiling CL can be reduced, ensuring aesthetics.

[0153] In addition, in the air conditioning system 1 according to this embodiment, the sensor assembly 300 further includes a power supply assembly 340. The power supply assembly 340 is arranged on the side of the seat portion 320 opposite to the panel 310, and includes a power supply circuit board 341 provided with relatively large-sized components such as a transformer. Therefore, the overall size of the sensor assembly 300 in the stacking direction of the panel 310 and the seat portion 320 is likely to increase. However, in the installed state, the power supply assembly 340 can be completely buried in the ceiling CL to hide the power supply assembly 340. Therefore, the thinning of the part exposed on the ceiling CL can be ensured, ensuring aesthetics in the installed state.

[0154] The present invention has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above embodiments.

[0155] For example, in the above-described embodiment, the case where the sensor assembly 300 is used in cooperation with the indoor unit 100 is taken as an example for illustration, but it is not limited thereto.

[0159] In addition, in the above-described embodiment, the inclined surface 3121 is a concave surface, but it is not limited thereto. The inclined surface 3121 can also be a flat surface, can also be a convex surface, and can also be a surface such as a stepped surface formed by a plurality of line segments as long as the surface is inclined as a whole with respect to the reference plane PLR when observed along the reference plane PLR, that is, as long as the line connecting one end (point PT1 in the above-described embodiment) and the other end (point PT2 in the above-described embodiment) of the surface is inclined with respect to the reference plane PLR when observed along the reference plane PLR.

[0160] In addition, in the above-described embodiment, the side surface 3122 on the side of the protrusion 312 opposite to the inclined surface 3121 is also an inclined surface or is a concave surface, but it is not limited thereto. The side surface 3122 can also not be a concave surface and can also not be an inclined surface.

[0161] In addition, in the above embodiment, in the first fixing structure MT1, the plurality of abutting portions include a pair of short strip-shaped first abutting portions AB1 that abut against the first circuit board 3312 from both sides in the Y direction, a pair of long strip-shaped second abutting portions AB2 that are closer to the X2 direction side than the pair of short strip-shaped abutting portions and abut against the first circuit board 3312 from both sides in the Y direction, two small protrusion-shaped third abutting portions AB3 that abut against the first circuit board 3312 from the X1 direction side and are adjacent in the Y direction, and a fourth abutting portion AB4 that abuts against the first circuit board 3312 from the X2 direction side. However, it is not limited thereto. The plurality of abutting portions may also include two peripheral edges that face each other and abut against the first circuit board 3312 from both sides (for example, two peripheral edges that are inclined relative to the reference plane PLR at the same angle as the first circuit board 3312 and face each other in the Y direction).

[0162] In addition, in the above embodiment, the sensor assembly 300 further includes a power supply assembly 340. However, it is not limited thereto. Depending on the situation, the power supply assembly 340 may also be omitted.

[0163] In addition, in the above embodiment, the inclined surface 3121 is provided near an edge 311a1 of the panel 310. However, it is not limited thereto. The inclined surface 3121 may also be provided at the center of the panel 310.

[0164] In addition, in the above embodiment, the electrical components further include one or more modules among an LED assembly, an illuminance sensor, and a buzzer. However, it is not limited thereto. The electrical components may also include a reset button.

[0165] In addition, in the above embodiment, the anti-theft mode and the night light mode can be turned on according to the detection result of the illuminance sensor of the sensor assembly 300, or can also be manually set and turned on through a mobile terminal.

[0166] In addition, in the above embodiment, the wind-avoiding-human mode and the wind-blowing-human mode can be selected, for example, by manually setting through a mobile terminal.

[0167] In addition, in the above embodiment, the control unit can adopt various forms such as a remote controller and a centralized controller.

[0168] In addition, the sensor assembly 300 of the present invention can be used not only as a household protection component but also in other places such as an office.
