Description

Equipment machine

Technical Field

The present invention relates to an equipment installed on a ceiling in a room of a building.

Background

In buildings such as houses, equipment devices such as air conditioners and ventilation fans are disposed. For example, a bathroom air conditioner for heating, ventilation, or the like is installed on the ceiling of a residential bathroom.

The bathroom air conditioner is provided such that a front panel having an air inlet and an air outlet is exposed to a ceiling panel of a bathroom, and a main body to which a fan or the like is attached is inserted into the ceiling through an opening of the ceiling panel. A terminal block for connecting a wiring or a power supply line of a remote controller is provided in a predetermined orientation on an upper surface of a main body of a general bathroom air conditioner.

The wiring and the inspection of parts are often performed from an inspection opening near the ceiling bathroom air conditioner. Since the installation direction of the bathroom air conditioner is determined by the position of the exhaust port, the installation direction of the terminal block on the device body is also determined. Therefore, depending on the position of the exhaust port, the terminal block may be positioned in a direction away from the access opening, and the above-described operation may be difficult.

Therefore, patent document 1 discloses an equipment including a terminal block that can be detached from and attached to an air conditioner main body. Patent document 2 discloses an apparatus including a plurality of terminal blocks having different wiring directions on an upper surface of a main body, and a shielding member for preventing erroneous wiring on each terminal block.

[ problem to be solved by the invention ]

In the device equipment of patent document 1, when the screw is removed by the screw driver in order to change the mounting position of the terminal block, the screw driver needs to be used while being erected vertically with respect to the ceiling. However, the screwdriver may not be able to vertically enter the ceiling due to reasons such as the height of the ceiling, and in such a case, there is a problem that workability is lost. When the terminal block is removed from the air conditioner main body in order to change the mounting position or mounting orientation of the terminal block, there is also a problem that the wiring connected to the terminal block is pulled. There is a risk of disconnection of the wiring due to the wiring being pulled.

The device and equipment of patent document 2 has a problem of high cost of parts because of the provision of a plurality of terminal blocks or shielding portions.

Disclosure of Invention

The present invention has been made to solve the above problems, and an object of the present invention is to provide an equipment which enables a terminal block to be used in an arrangement suitable for wiring connection, inspection, and other operations after installation, and which can reduce the number of components and thus reduce the cost.

[ MEANS FOR solving PROBLEMS ] A method for solving the problems

The technical means of the present invention adopted to solve the above problems are as follows.

An equipment device installed on a ceiling of a building, comprising: a main body part provided on a ceiling; a terminal block supported to be movable along an upper surface portion of the main body; an operation unit that moves the terminal block in the same direction of the main body side as the terminal block with respect to a rotation axis of a movement path of the terminal block; and a gripping portion for gripping the operation portion.

In the equipment of the present invention, when the terminal block faces the opposite side of the access opening, after the main body portion is provided on the ceiling of the building, the electrical service provider grips the grip portion provided at the tip of the operation portion from the access opening provided on the ceiling and operates the operation portion, whereby the terminal block moves and changes its position and orientation. This enables the position and orientation of the terminal block to be changed in accordance with the orientation of the access opening.

Detailed Description

Hereinafter, embodiments of the facility apparatus according to the present invention will be described with reference to the drawings.

[ first embodiment ]

Referring to fig. 1 to 10, a configuration example of a bathroom air conditioner 100 according to the present embodiment will be described. The air conditioner 100 shown in fig. 1 includes a main body 10 covered with a metal casing and is installed on a ceiling. As shown in fig. 4 and 5, the bathroom air conditioner 100 has a main body 10 that enters the back side of a ceiling 104 of a bathroom. The front plate 18, which forms an air inlet and an air outlet, is exposed to the ceiling 104 of the bathroom.

As shown in fig. 4, the bathroom air conditioner 100 is connected to an exhaust duct 102 at a duct joint 19 attached to the main body 10. The exhaust duct 102 determines a piping path according to the structure of a building in which the bathroom is installed. An access opening 103 for use in installation work, inspection, and the like of the bathroom air conditioner 100 is opened in the ceiling 104 of the bathroom.

Therefore, the bathroom air conditioner 100 is installed on the ceiling 104 of the bathroom in an orientation selected according to the structure of the building. For example, the arrangement shown in fig. 4 in which the first side surface 10a of the body 10 faces the service opening 103 and the arrangement shown in fig. 5 in which the opposite second side surface 10b of the first side surface 10a of the body 10 faces the service opening 103 are selected.

As shown in fig. 4, when the first side surface 10a is directed to the service opening 103, the terminal block 3 is fixed to the first side surface 10a side of the connection portion 31 provided with the electric wire connection port 30 shown in fig. 6 to 8, and to the third side surface 10d side (the opposite side to the channel joint 19) of the first side surface 10a at a position rotated by 45 ° in the horizontal direction with respect to the upper surface portion 10c, as shown by the solid line in fig. 1. The terminal block 3 is set to a first position. When the second side surface 10b of the main body 10 shown in fig. 5 faces the service opening 103, the terminal block 3 is fixed at a position rotated by 45 ° in the horizontal direction with respect to the upper surface portion 10c, as shown by a dotted line in fig. 1, toward the second side surface 10b and toward the third side surface 10d with respect to the second side surface 10b, in the connection portion 31 where the electric wire connection port 30 shown in fig. 6 to 8 is provided. The position of the terminal block 3 is set to the second position. The terminal block 3 can be moved to the second position by being rotated by about 90 ° along the upper surface portion 10c from the first position.

An upper surface portion 10c of the main body portion 10 shown in fig. 2 is covered with a cover member (hereinafter, referred to as a main body cover 11). Fig. 3 is a view of the main body cover 11 removed. The upper surface portion 10c includes a single terminal block 3 rotatably supported by connecting the external wiring 2, an operation portion 44 for rotating the terminal block 3, and a grip portion 5 for gripping the operation portion 44 by a hand of a person during a rotating operation. The operation portion 44 is provided on the operation member 4 for rotating the terminal block 3. Upper surface portion 10c has a plane surface lower than the top surface of main body portion 10 by one level as an installation space in which terminal block 3, operation portion 44, and the like are installed.

The main body 10 includes a fan, a motor for driving the fan, a heater for heating air blown by the fan, a control board for driving the fan and the heater, and the like. The terminal block 3 is connected to a control board or the like not shown by a wiring 2 a.

The terminal block 3 shown in fig. 6 and 7 includes a plurality of wire connection ports 30. The stripped portion of the wiring 2 shown in fig. 7 is inserted into the electric wire connection port 30 from the connection portion 31 side, whereby the wiring 2 is fixed and electrically connected.

In the terminal block 3 of the present example, 3 wire connection ports 30 are arranged in a row, and 3 wires 2 are connected in parallel. Terminal block 3 is supported by mounting portion 41b on base portion 41a of operation member 4. The operation member 4 is attached to the main body cover 11 (not shown in these figures) rotatably in the horizontal direction along an upper surface portion 10c of the main body 10 shown in fig. 8.

Operation member 4 is disposed such that mounting portion 41b of terminal block 3 is inclined at a predetermined angle with respect to base portion 41a of operation member 4. Therefore, as shown in fig. 8, the 3 wire connection ports 30 of the terminal block 3 are attached obliquely to the upper surface portion 10c of the main body 10.

Thus, when the wires 2 are inserted into the 3 wire connection ports 30 of the terminal block 3, the 3 wires 2 are vertically displaced and visible even when the terminal block 3 is viewed from the side, and therefore, whether or not the wires 2 are inserted into the respective wire connection ports 30 can be easily visually recognized.

As shown in fig. 9, operation member 4 includes a rotation shaft 42 that serves as a rotation center of 1 point of terminal block 3, an operation arm 43 extending from rotation shaft 42, a base portion 41a that houses terminal block 3, an operation portion 44 extending from base portion 41a, and a grip portion 5 that grips operation portion 44 with a hand of a person. The operation member 4 is located on the third side surface 10d side, and the third side surface 10d side is the same main body side surface direction as the terminal block 3 with respect to the rotation axis 42 which becomes the center of rotation of the terminal block 3. The base portion 41a is located on the opposite side of the rotation shaft 42 with respect to the operation arm portion 43. The operation portion 44 extends from the base portion 41a in a circumferential direction of a circle having a radius equal to that of the operation arm portion 43 in a direction in which the base portion 41a rotates about the rotation shaft 42.

In order to facilitate the rotation of the operation unit 44 by holding it with a hand, the grip 5 located at the tip of the operation unit 44 has a shape in which an elongated plate is bent with respect to the long side.

The rotary shaft 42 in this example has a convex portion 42a at the center thereof. The protrusion 42a is attached to the rotation hole 12a of the body cover 11 shown in fig. 2. The terminal block 3 rotates about a projection 42a of a rotating shaft 42 attached to the rotating hole 12 a.

As shown in fig. 9 and 14, the operating member 4 is provided with a screw fastening abutment portion 44a on the distal end side of the operating portion 44 and in the vicinity of the grip portion 5. The contact portion 44a has a locking portion 44b formed of a groove or a hole. As shown in fig. 11, when the terminal block 3 is in the first position, the abutting portion 44a is disposed parallel to the second side surface 10 b. The contact portion 44a is provided to fix the terminal block 3 at the first position.

As shown in fig. 9 and 14, the operating portion 44 is provided with an abutting portion 44c for screw fastening on the grip portion 5 side of the base portion 41 a. The contact portion 44c has a locking portion 44d formed of a groove or a hole. As shown in fig. 12, when the terminal block 3 is in the second position, the abutting portion 44c is parallel to the second side surface 10 b. The contact portion 44c is provided to fix the terminal block 3 at the second position.

As shown in fig. 9, the operating member 4 has a protruding portion 45 at the base portion of the base portion 41a and the operating portion 44. The protrusion 45 is provided to fix the position of the terminal block 3 before and after rotation.

As shown in fig. 10, the operation arm portion 43 is provided with

claw portions

43a and 43b on the back side thereof for fastening the wiring 2 a. The wiring 2a extends from the terminal block 3, is collected near the back side of the rotating shaft 42 by the back side of the operation arm 43, and is connected to a control board or the like in the main body 10. This can suppress the stretching, biting, and twisting of the wiring 2a when the terminal block 3 is rotated. In addition, since the rotation angle of the terminal block 3 of this example is about 90 °, the twist of the wiring 2a can be reduced as compared with the case where the rotation angle is larger than 90 °, for example.

As shown in fig. 2, the body cover 11 has a top surface 12 and a side surface 13, and is attached to the upper surface portion 10c of the body 10 with screws or the like, not shown. The side surface 13 is set shorter than the third side surface 10d of the main body 10, and constitutes a wall on the opposite side of the main body 10 from the duct joint 19. The main body cover 11 has a shape covering the side surfaces and the upper surface of the terminal block 3, the operation member 4, and the like shown in fig. 3, and is made of a metal plate material. Therefore, the rotation of the terminal block 3 in the vertical (vertical) direction when the terminal block 3 is rotated can be restricted.

The top surface 12 of the main body cover 11 shown in fig. 2 has a rotation hole 12a which becomes the center of rotation of the terminal block 3. The protruding portion 42a of the rotation shaft 42 of the operation member 4, which serves as the rotation center of the terminal block 3, is attached to the rotation hole 12a of the main body cover 11. Thereby, terminal block 3 rotates in the horizontal direction with respect to upper surface 10c about rotation hole 12a of rotation shaft 42.

The main body cover 11 has a first opening 13a and a second opening 14a adjacent to each other on the left and right sides of the side surface 13. The first opening 13a faces the electric wire connection port 30 of the terminal block 3 at the first position. The second opening 14a faces the electric wire connection port 30 of the terminal block 3 at the second position. The top surface 12 is cut obliquely with respect to the side surface 13 of the top surface 12 corresponding to the position of the terminal block 3 before and after rotation. The terminal block 3 is rotatably moved between the first opening 13a and the second opening 14a relative to the side surface 13. This enables connection and inspection of the wiring 2 to be performed before and after the rotation of the terminal block 3 with the main body cover 11 attached. On the other hand, these operations can be prevented during the rotation.

The main body cover 11 has

holes

11a and 11b for fixing the position of the terminal block 3 to the top surface 12 thereof. As shown in fig. 11, the hole 11a is provided at a position vertically above the protrusion 45 when the terminal block 3 is at the first position. When the terminal block 3 is in the first position, the protrusion 45 protrudes from the hole 11a and is engaged and fixed.

As shown in fig. 12, the hole 11b is provided at a position vertically above the protruding portion 45 when the terminal block 3 is at the second position. When the terminal block 3 is in the second position, the protrusion 45 protrudes from the hole 11b and is engaged and fixed. Even when the terminal block 3 is not screwed before and after rotation, the position of the terminal block 3 can be fixed by the engagement of the protrusion 45 with the

holes

11a and 11 b.

As shown in fig. 2 and 13, the main body 10 includes a rotation restricting portion 14b extending from the side surface 13 toward the inside of the main body cover 11 at the outer edge portion of the second opening portion 14a on the side surface 13 side. The rotation restricting portion 14b has a screw hole 14c into which the screw 46 is inserted from the second side surface 10b side.

The rotation restricting portion 14b is parallel to the second side surface 10 b. As shown in fig. 11, when the terminal block 3 is in the first position, the contact portion 44a of the operating member 4 is parallel to the second side surface 10 b. Therefore, at this time, the rotation restricting portion 14b abuts against the abutting portion 44 a. Since the screw hole 14c of the rotation restricting portion 14b is aligned with the position of the locking portion 44b of the contact portion 44a, the rotation of the terminal block 3 and the operating member 4 is restricted by fastening them with the screw 46.

As shown in fig. 2, the body portion 10 includes a rotation restricting portion 14d extending vertically downward from the top surface 12 at an outer edge portion of the second opening portion 14a on the second side surface 10b side. The rotation restricting portion 14d has a screw hole 14e into which the screw 46 is inserted from the second side surface 10b side.

The rotation restricting portion 14d is parallel to the second side surface 10 b. As shown in fig. 12, when the terminal block 3 is at the second position, the contact portion 44c of the base portion 41a of the terminal block 3 is parallel to the second side surface 10 b. Therefore, at this time, the rotation restricting portion 14d abuts against the abutting portion 44 c. Since the screw hole 14e of the rotation restricting portion 14d is aligned with the position of the locking portion 44d of the contact portion 44c, the rotation of the terminal block 3 and the operation member 4 is restricted by fastening them with the screw 46. The

rotation restricting portions

14b and 14d may be configured to restrict the rotation of the terminal block 3 and the operation member 4 by the terminal block 3 coming into contact with the

rotation restricting portions

14b and 14 d.

< example of installation operation of bathroom air conditioner >

Next, the setting operation of the bathroom air conditioner 100 will be described.

As shown in fig. 11, in the bathroom air conditioner 100 in the initial state (factory shipment), the terminal block 3 is fixed at the first position. The protruding portion 45 protrudes from the hole 11a of the body cover 11. The contact portion 44a of the operating member 4 contacts the rotation restricting portion 14b of the main body cover 11. The position of the terminal block 3 is fixed by fastening the locking portion 44b of the contact portion 44a and the screw hole 14c of the rotation restricting portion 14b with a screw 46 of a fixing member. This restricts the rotational movement operation about the rotation shaft 42 as a fulcrum.

When the main body 10 of the bathroom air conditioner 100 in the initial state is installed in the ceiling 104 in the orientation shown in fig. 4, the first side surface 10a and the opposing surface of the terminal block 3 are installed so as to be shifted in the horizontal direction at an inclination of 45 ° as shown in fig. 8. Thereby, the wire connection port 30 is visible from the first side surface 10a side. Since the terminal block 3 is attached to the base portion 41a with an inclination in the vertical direction, the 3 wire connection ports 30 of the terminal block 3 can be seen from the first side surface 10a side. Therefore, the work of connecting the wiring 2 to the wire connection port 30 can be performed from the access hole 103 (see fig. 4). Since the electrical service provider can visually recognize whether or not the wiring 2 is inserted into the electric wire connection port 30 through the access opening 103, the electrical service provider can reliably insert the wiring 2 into the electric wire connection port 30 from the access opening 103 side. Therefore, the operating member 4 does not need to be rotated. Further, since the grip portion 5 faces the opposite side of the access opening 103, the movement of the terminal block 3 cannot be performed. This can prevent malfunction.

In contrast, as shown in fig. 5, when the second side surface 10b of the main body 10 is provided toward the service opening 103, the terminal block 3 needs to be rotated to the second position so as to face the service opening 103.

When rotating the terminal block 3, first, as shown in fig. 11, the electrical service provider removes the screw 46 for fixing the position of the terminal block 3 from the locking portion 44b by an operation from the second side surface 10b side. Next, the electric utility company holds the grip portion 5 and moves the position of the terminal block 3 to a position where the protrusion 45 abuts against the hole 11b of the body cover 11. At this time, the operation member 4 rotates around the convex portion 42a of the rotation shaft 42 and around the operation arm portion 43. When the terminal block 3 is rotated in the middle, the protrusion 45 is retracted into the main body cover 11. The terminal block 3 is rotated from the first position to the second position shown in fig. 12 through the inside of the main body cover 11. When the terminal block is rotated to the second position, the abutting portion 44c abuts against the rotation restricting portion 14d, and the locking portion 44d is aligned with the screw hole 14 e.

After the rotation, the electrical service provider fixes the terminal block 3 to the screw hole 14e of the body cover 11 with the screw 46 from the second side surface 10b side. The position of the terminal block 3 is fixed by fastening the locking portion 44d and the screw hole 14e of the rotation restricting portion 14d with a screw 46. This restricts the rotational movement of the terminal block 3 about the rotation shaft 42.

In this way, the electrical service provider moves the operation portion 44 and rotates the terminal block 3 to the second position, thereby making it possible to view the 3 electric wire connection ports 30 of the terminal block 3 through the access opening 103.

By providing the

rotation restricting portions

14b and 14d in the body cover 11 and providing the

contact portions

44a and 44c in the operating member 4, the screw 46 for fixing the position of the terminal block 3 can be operated from the side of the second side surface 10b regardless of whether the terminal block 3 is in the first position or the second position. Therefore, after the bathroom air conditioner 100 is set in the orientation shown in fig. 5, the screw 46 can be attached and detached and the operation member 4 can be rotated from the access opening 103.

Thus, even after the bathroom air conditioner 100 is installed in a building, the electrical service provider can move the terminal block 3 to a position suitable for work such as connection or inspection of the wiring 2, and can use the terminal block. In this case, since it is not necessary to vertically insert the screw driver into the ceiling 104 with respect to the ceiling surface 12, the above-described work can be efficiently performed even when the ceiling 104 is low. The operation of changing the position of the terminal block 3 may be performed by one hand. Since the above-described effects can be obtained by providing the single terminal block 3 and the operation member 4 for moving the terminal block 3, the number of parts can be reduced, and low cost can be achieved.

When the bathroom air conditioner 100 is installed in a bathroom, the constructor of the bathroom air conditioner 100 does not need to care about the position of the air discharge duct 102 and performs an operation of changing the position of the terminal block 3 before installing the device in the ceiling 104 of the bath according to the installation direction of the bathroom air conditioner 100 shown in fig. 4 or 5. Therefore, the burden of work on the operator can be reduced, and the work time can be shortened as compared with a structure in which the terminal block 3 is detached from the main body 10 and re-attached with the orientation changed. Further, the division of the responsibility of the work can be made clear between the construction worker who installs the bathroom air conditioner 100 in the bathroom and the electric construction worker who connects the wiring 2 to the bathroom air conditioner 100.

As described above, the operation member 4 is located on the same direction side as the terminal block 3 with respect to the rotation shaft 42 that serves as the center of rotation of the terminal block 3. The operation portion 44 extends in the rotation direction around the rotation axis 42 and around the operation arm portion 43. As shown in fig. 11, when the terminal block 3 is at the first position, the operation portion 44 of the operation member 4 is fixed in a shape along the inner wall of the side surface 13. As shown in fig. 12, when the terminal block 3 is at the second position, the operation portion 44 of the operation member 4 is fixed in a shape along the outer wall of the second side surface 10b of the main body portion 10.

Further, the terminal block 3 is rotated by 90 ° from the first position to the second position, and its trajectory is confined within the main body cover 11. At this time, the terminal block 3 is rotated only in the horizontal direction because the movement in the vertical direction is restricted by the body cover 11.

Accordingly, the space of upper surface portion 10c necessary for rotation of operation portion 44 and terminal block 3 is substantially the same, and the operating space of terminal block 3 and operation member 4 before and after rotation is limited to the range from rotation shaft 42 to terminal block 3. Since the locus of the operation portion 44 does not greatly protrude when the main body portion 10 is viewed from above, the working space can be reduced. Therefore, it is not necessary to provide a large space around the main body 10 for moving the operation unit 44 in the horizontal direction. Further, it is not necessary to obtain a large space lower than the upper surface portion 10c of the main body 10. Therefore, a wide space can be secured for the equipment housed in the main body 10.

[ second embodiment ]

Next, a configuration example of the bathroom air conditioner 200 as the second embodiment will be described. The length of the operating portion 64 of the bathroom air conditioner 200 in the extending direction is set longer than the operating portion 44 of the bathroom air conditioner 100 described in the first embodiment. In the bathroom air conditioner 200, a description will be given by giving new symbols to portions different from the bathroom air conditioner 100 of the first embodiment. In the bathroom air conditioner 200, the same portions as those of the bathroom air conditioner 100 of the first embodiment are omitted from detailed description.

The air conditioner 200 shown in fig. 15 includes a main body 10 covered with a metal casing, and is installed on a ceiling 104 of a building. The body portion 10 has a channel connector 19.

The first position and the second position of the terminal block 3 are the same positions as those described in the first embodiment, and the position of the terminal block 3 facing the first side surface 10a side of the main body 10 is set as the first position. The position of the terminal block 3 facing the second side surface 10b side of the main body 10 is set to the second position. In this example, the terminal block 3 is also rotated by about 90 ° from the first position to the second position.

The upper surface portion 10c includes: a terminal block 3 rotatably supporting the wiring 2 connected thereto from the outside; an operation unit 64 for rotating the terminal block 3; and a gripping unit 5 for gripping the operation member 6 with a human hand during the rotational movement operation. The upper surface portion 10c has a plane surface lower than the top surface of the main body portion 10 by one step as an installation space in which the terminal block 3, the operation member 6, and the like are installed. The operation portion 64 is provided to the operation member 6.

The operation member 6 shown in fig. 15 is different from the operation member 4 in that the operation portion 64 is set longer than the operation portion 44 of the operation member 4 of the first embodiment. By setting the operation portion 64 to be long, the position of the grip portion 5 when the terminal block 3 is at the first position can be made closer to the service opening 103. Therefore, the electrical service provider can perform the rotation operation of the terminal block 3 at a position closer to the service opening 103.

The operation member 6 is located on the third side 10d, which is the same main body side direction as the terminal block 3, with respect to the rotation shaft 62 that is the center of rotation of the terminal block 3. Therefore, the operating space of terminal block 3 and upper surface portion 10c of operation member 6 before and after rotation is limited to the range from rotation shaft 62 to terminal block 3. This allows a device larger than the conventional example to be housed in the main body 10.

The operating member 6 is provided with a screw fastening abutment portion 64a on the distal end side of the operating portion 64 and in the vicinity of the grip portion 5. The contact portion 64a has a locking portion 64b formed of a groove or a hole. When the terminal block 3 is in the first position, the abutting portion 64a is parallel to the second side face 10 b. The contact portion 64a is provided to fix the terminal block 3 at the first position.

The operating portion 64 is provided with an abutment portion 64c for screw fastening on the grip portion 5 side of the base portion 61 a. The contact portion 64c has a locking portion 64d formed of a groove or a hole. When the terminal block 3 is in the second position, the abutting portion 64c is parallel to the second side face 10 b. The contact portion 64c is provided to fix the terminal block 3 at the second position.

The structure of the back side of the operation arm portion 63 is the same as that of the operation member 4 shown in fig. 10.

As shown in fig. 15, the upper surface portion 10c of the main body portion 10 is covered with a main body cover 21. The main body cover 21 has a first opening 23a and a second opening 24a on adjacent left and right sides of the side surface 23. The main body cover 21 of this example is different from the main body cover 11 of the first embodiment only in the direction in which the second opening 24a opens. The second opening 24a opens in parallel with the second side surface 10b of the main body 10.

The main body 10 includes a rotation restricting portion 24b extending from the side surface 23 toward the inside of the main body cover 21 at the outer edge portion on the side surface 23 side of the second opening portion 24 a. The rotation restricting portion 24b has the same shape as the rotation restricting portion 14b of the first embodiment shown in fig. 2, and exerts the same function. The rotation restricting portion 24b has a screw hole 24c into which the screw 66 is inserted from the second side surface 10b side. When the terminal block 3 is in the first position, the rotation restricting portion 24b abuts against the abutting portion 64a of the operating member 6. The screw hole 24c of the rotation restriction portion 24b and the engagement portion 64b of the contact portion 64a are fastened by the screw 66, and thereby the rotation of the terminal block 3 and the operation member 6 before the rotation is restricted.

As shown in fig. 16, the main body 10 includes a rotation restricting portion 24d at an outer edge portion of the second opening 24a on the second side surface 10b side. The rotation restricting portion 24d has the same shape as the rotation restricting portion 14d shown in fig. 2, and exerts the same function. The rotation restricting portion 24d has a screw hole 24e into which the screw 66 is inserted from the second side surface 10b side. As shown in fig. 16, when the terminal block 3 is at the second position, the rotation restricting portion 24d abuts against the abutting portion 64c of the base portion 61a of the terminal block 3. The screw hole 24e of the rotation restriction portion 24d and the engagement portion 64d of the contact portion 64c are fastened by the screw 66, and thereby the rotation of the terminal block 3 and the operation member 6 after the rotation is restricted.

In this example, since the length of the operation portion 64 in the extending direction is set to be long, when the terminal block 3 is at the first position, the fixing position of the screw 66 is closer to the service opening 103 than the fixing position of the screw 46 of the first embodiment. This makes it easier for the electrical service provider to remove the screw 66.

The rotation direction of the terminal block 3 is not limited to the above direction. Fig. 17 shows a bathroom air conditioner 200' as a modification of the bathroom air conditioner 200. The terminal block 3 of the bathroom air conditioner 200' may be rotated from a position facing the third side surface 10d on the opposite side of the duct joint 19 indicated by a solid line in the figure to a position facing the second side surface 10b indicated by a dotted line in the figure. In this case, the operation portion 64 ' of the operation member 6 ' extends from the base portion 61a ' so as to be perpendicular to the direction of the terminal block 3 and horizontal to the upper surface portion 10 c. The angle of rotation of the terminal block 3 is not limited to a right angle or an acute angle, and may be any angle of rotation.

Further, the movement operation of the operation member 6 is not limited to the rotational movement operation. For example, fig. 18 shows an operation member 6 ″ as a modification of the operation member 6. Next, a case where the terminal block 3 moves on the trajectory 33 indicated by the one-dot chain line in the drawing will be described. At this time, the rotation axis of the movement path of the terminal block 3 moves from the virtual axis O to the virtual axis O'.

The operation member 6 ″ supports the terminal block 3 movably to the upper surface portion 10c of the main body portion 10 (see fig. 15). The operation member 6 "includes a base portion 61a that houses the terminal block 3," a guide shaft 62 that guides movement of the terminal block 3, "an operation arm portion 63 extending from the guide shaft 62," an operation portion 64 that moves the terminal block 3, "and a grip portion 5 that grips the operation portion 64" with a human hand. The operation portion 64 ″ is located in the same main body side direction as the terminal block 3 with respect to the virtual axis O, O' of the movement path of the terminal block 3.

As shown by dotted lines in fig. 18, a guide hole 22a ″ for guiding the movement of the terminal block 3 is provided in the top surface 22 of the body cover 21 shown in fig. 16. The guide hole 22a "is fitted with the convex portion 62 a" of the guide shaft 62 ". The guide shaft 62 "moves along the guide hole 22 a", whereby the terminal block 3 moves along the trajectory 33.

In this example, the guide shaft 62 "is provided on the opposite side of the base portion 61 a" with respect to the operation arm portion 63 ", but is not limited thereto. For example, the guide shaft 62 "may be provided vertically above the base portion 61 a" of the terminal block 3. In this case, since the arm portion 63 ″ does not need to be operated, the space required for storing and moving the terminal block 3 can be further saved.
