The wiring (45a) of the camera (45) is held inside the first binding member (75a). A power supply line (45b) is held inside the second binding member (75b).

With the cover (55) attached to the box body (51), the wiring (45a) of the camera (45) is inserted into the first wiring hole (57a). Therefore, the wiring (45a) is located near the upper surface of the lower bottom portion (52a) inside the first wiring hole (57a). In other words, inside the first wiring hole (57a), the height position of the wiring (45a) is lower than the height position of the upper bottom portion (52c).

With the cover (55) attached to the box body (51), the power line (45b) is inserted into the second wiring hole (57b). Therefore, the power line (45b) is located near the upper surface of the lower bottom portion (52a) inside the second wiring hole (57b). In other words, inside the second wiring hole (57b), the height position of the power line (45b) is lower than the height position of the upper bottom portion (52c).

If water adheres to the wiring (45a) of the camera (45) due to the influence of rain leaks, this water may flow through the wiring (45a) and inside the box (50). On the other hand, in the present embodiment, the position of the wiring (45a) gradually increases from the first wiring hole (57a) to the upper bottom portion (52c). Therefore, it is possible to prevent the water adhering to the wiring (45a) from reaching the upper bottom portion (52c). This makes it possible to prevent this water from adhering to electrical components such as the terminal block (71) and the power supply board (72).

Similarly, if water adheres to the power supply line (45b) due to the influence of a rain leak or the like, this water may flow through the power supply line (45b) and flow inside the box body (50). On the other hand, in the present embodiment, the position of the power supply line (45b) gradually increases from the second wiring hole (57b) to the upper bottom portion (52c). Therefore, it is possible to prevent the water adhering to the power supply line (45b) from reaching the upper bottom portion (52c). This makes it possible to prevent this water from adhering to electrical components such as the terminal block (71) and the power supply board (72).

It is assumed that a tensile force acts on the wiring (45a) from the outside of the box body (50). The image pickup control board (74) to which the wiring (45a) is connected is located higher than the upper bottom (52c). On the other hand, the first wiring hole (57a) through which the wiring (45a) is inserted is located lower than the upper bottom portion (52c). Therefore, the stress acting on the wiring (45a) can be dispersed in the horizontal direction and the height direction. As a result, the stress concentration of the wiring (45a) can be suppressed, and the wiring (45a) can be suppressed from coming off or breaking from the image pickup control board (74).

Similarly, it is assumed that a pulling force acts on the power supply line (45b) from the outside of the box body (50). The terminal block (71) to which the power line (45b) is connected is located higher than the upper bottom (52c). On the other hand, the second wiring hole (57b) through which the power line (45b) is inserted is located lower than the upper bottom portion (52c). Therefore, the stress acting on the power supply line (45b) can be dispersed in the horizontal direction and the height direction. As a result, the stress concentration of the power supply line (45b) can be suppressed, and the power supply line (45b) can be suppressed from coming off or being cut off from the terminal block (71).

The power line (45b) and the wiring (45a) of the camera (45) are inserted into different wiring holes (57a, 57b). As a result, the distance between the power supply line (45b) and the wiring (45a) can be secured. As a result, it is possible to suppress the wiring including the signal line (45a) from being affected by the noise of the power supply line (45b) which is a high voltage wiring.

A spring washer may be provided between the upper nut (N1) and the upper washer (W1). A spring washer may be provided between the lower nut (N2) and the lower washer (W2).

<Second convex part>
The second short side (86) on the second end (82) side of the mounting plate (80) is divided into two pieces with a notch (90) in between. A second convex portion (92) protruding in the plate thickness direction is formed on each piece of the second end portion (82). As shown in FIG. 9, each second convex portion (92) of the present embodiment projects downward from the second end portion (82). The protrusion height h1 of each second convex portion (92) is larger than the plate thickness d of the mounting plate (80). The protrusion height h1 of each second convex portion (92) is larger than the protrusion height h2 of the first convex portion (87).

The second convex portion (92) prohibits the mounting plate (80) from coming off the suspension bolt (B) through the notch (90). Specifically, when the fastening force of the upper nut (N1) and the lower nut (N2) is relatively loose, the relative positions of the notch (90) and the suspension bolt (B) change, and the mounting plate (80) becomes. There is a possibility of moving to the first end (81) side. As the mounting plate (80) moves further, the lower washer (W2) touches the inner edge of the pair of second convex portions (92). This makes it possible to prevent the mounting plate (80) from coming off the suspension bolt (B). In order to ensure that the pair of second convex portions (92) and the lower washer (W2) are in contact with each other, the outer diameter of the lower washer (W2) is made larger than the distance between the pair of second convex portions (92). Is good.

When the lower washer (W2) is omitted, the second convex portion (92) may be configured to come into contact with the lower nut (N2). In this case, the minimum outer diameter of the lower nut (N2) may be larger than the distance between the pair of second convex portions (92).

Both of the two second convex portions (92) may be projected upward. One of the two second convex portions (92) may be projected upward and the other may be projected downward. Even in these configurations, the removing bolt (W2) can be prevented from coming off from the mounting plate (80) by bringing the second convex portion (92) into contact with the nut or the second convex portion (92) with the bolt.

<Dimensions on the second end side of the mounting plate>
The mounting plate (80) is configured to be rotatable around the suspension bolt (B).

As shown in FIGS. 8 to 10, the center (P) of the insertion portion (91) of the suspension bolt (B) in the notch (90) and the outer edge of the mounting plate (80) are larger than the center (P). Let L1 be the maximum length with the part near the second end (82). As shown in FIG. 6, the distance between the center (P) of the insertion portion (91) and the air conditioner (10) is L2. Strictly speaking, the minimum distance between the center (P) of the insertion portion (91) and the air conditioner (10) is L2. The center (P) coincides with the axis of the suspension bolt (B). The mounting plate (80) is configured such that L1 is shorter than L2. Specifically, by forming the first chamfered portion (C1) and the second chamfered portion (C2) at the second end portion (82) as described above, L1 of the mounting plate (80) can be shortened. As a result, the mounting plate (80) can be rotated around the suspension bolt (B) without the second end portion (82) of the mounting plate (80) interfering with the air conditioner (10). ..

-Installation work of additional unit-
The installation work of the additional unit (U) will be described in detail.

It is assumed that the mounting plate (80) is fixed to the hanging bolt (B) with the box body (50) attached to the mounting plate (80). In this case, since the weight of the box body (50) acts on the mounting plate (80), the work of fixing the mounting plate (80) to the suspension bolt (B) becomes complicated. Alternatively, a tool such as a spanner tends to interfere with the box body (50). On the other hand, by fixing only the mounting plate (80) to the suspension bolt (B) first, the work of fixing the mounting plate (80) becomes easy.

The suspension bolt (B) is positioned at the insertion portion (91) through the notch (90) in the mounting plate (80). In this state, the operator fixes the third fastening member (95) to the suspension bolt (B). As shown in FIG. 6, in the present embodiment, the mounting plate (80) is fixed to the suspension bolt (B) above the support portion (48) of the air conditioner (10).

The operator brings the side edge (61a) of the first plate (61) of the box body (50) into contact with the inner edge of the first convex portion (87) of the mounting plate (80). In this state, the operator slides the box body (50) in the longitudinal direction of the first plate (61), so that the alignment of the box body (50) becomes easy. In the example of FIG. 10, the intermediate portion in the longitudinal direction of the box body (50) is installed on the upper surface of the mounting plate (80). In this state, the operator overlaps the first mounting hole (63) and the third mounting hole (88) in the plate thickness direction of the mounting plate (80). At the same time, the operator superimposes the second mounting hole (64) and the fourth mounting hole (89) in the plate thickness direction of the mounting plate (80). At this time, the first convex portion (87) comes into contact with the mounting plate (80), which facilitates the alignment of these.

Next, the operator inserts the first fastening member (65) into the first mounting hole (63) and the third mounting hole (88), and fixes the first plate (61) and the mounting plate (80). The operator inserts the second fastening member (66) into the second mounting hole (64) and the fourth mounting hole (89), and fixes the second plate (62) and the mounting plate (80).

Similar to the first embodiment, a suspension bolt (B) is fixed to each support portion (48).

-Driving operation-
The operating operation of the air conditioner (10) according to the second embodiment will be described with reference to FIGS. 11 and 12. The air conditioner (10) is configured to be capable of performing cooling and heating operations.

Similar to the first embodiment, in the cooling operation, the indoor heat exchanger (37) becomes an evaporator, and in the heating operation, the indoor heat exchanger (37) becomes a condenser (radiator). In the heating operation, the humidifier (13) is operated to humidify the air. In the cooling operation and the heating operation, the air supply fan (34a) and the exhaust fan (34b) operate. Along with this, the outdoor air (OA) is taken into the air supply flow path (33A) from the outside air port (32b). At the same time, indoor air (RA) is taken into the exhaust flow path (33B) from the inside air port (31a). As a result, the indoor space is ventilated.

In the cooling operation, the outdoor air (OA) taken into the air supply flow path (33A) flows through the first passage (12a) of the total heat exchanger (12). On the other hand, the indoor air (RA) taken into the exhaust flow path (33B) flows through the second passage (12b) of the total heat exchanger (12). For example, in summer, outdoor air (OA) has a higher temperature and humidity than indoor air (RA). Therefore, in the total heat exchanger (12), the latent heat and sensible heat of the outdoor air (OA) are applied to the indoor air (RA). As a result, air is cooled and dehumidified in the first passage (12a). In the second passage (12b), the air to which latent heat and sensible heat are applied passes through the exhaust port (32a) and is discharged to the outdoor space as exhaust air (EA).

The air cooled and dehumidified in the first passage (12a) is cooled by the indoor heat exchanger (37) and then passes through the humidifier (13) in the stopped state. After that, this air passes through the air supply port (31b) and is supplied to the interior space as supply air (SA).

In the heating operation, the outdoor air (OA) taken into the supply air flow path (33A) flows through the first passage (12a) of the total heat exchanger (12). On the other hand, the indoor air (RA) taken into the exhaust flow path (33B) flows through the second passage (12b) of the total heat exchanger (12). For example, in winter, outdoor air (OA) has a lower temperature and humidity than indoor air (RA). Therefore, in the total heat exchanger (12), the latent heat and sensible heat of the indoor air (RA) are applied to the outdoor air (OA). As a result, air is heated and humidified in the first passage (12a). In the second passage (12b), the air deprived of latent heat and sensible heat passes through the exhaust port (32a) and is discharged to the outdoor space as exhaust air (EA).

The air heated and humidified in the first passage (12a) passes through the humidifier (13) after being heated by the indoor heat exchanger (37). In the humidifier (13), the water contained in the water absorbing member (13a) is applied to the air. The air that has passed through the humidifier (13) passes through the air supply port (31b) and is supplied to the interior space as supply air (SA).

<Additional unit>
As schematically shown in FIGS. 13 and 14, the second embodiment has an additional unit (U) similar to that of the first embodiment. The air treatment unit (1) is composed of the air conditioner (10) and the additional unit (U).

FIG. 13 is an example in which the addition unit (U) is fixed to the suspension bolt (B) corresponding to the first support portion (48A). As in the first embodiment, the mounting plate (80) is rotatably fixed to the suspension bolt (B). Therefore, as shown in FIG. 14, the angle of the mounting plate (80) can be changed and the position of the box body (50) can be changed.

If the box body (50) is arranged in the maintenance space (15) in front of the front plate (23) of the casing (20), the box body (50) may be an obstacle during maintenance work. Therefore, as shown in FIG. 14, the maintenance space (15) can be sufficiently secured by rotating the box body (50) toward the first side plate (25).

The other effects are the same as those of the first embodiment.
