Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separation type air conditioner composed of an indoor unit and an outdoor unit, and a connector for electrically connecting wiring extending from the outdoor unit and wiring of the indoor unit, Regarding improvement of support structure.

[0002]

2. Description of the Related Art An indoor unit is mounted on a wall surface of an air-conditioned room, and an outdoor unit is arranged outside a house.
Separation type air conditioners that are connected through wiring and piping are often used.

Usually, the wiring has an F cable extended from the outdoor unit. That is, the F cable penetrates the wall of the air-conditioned room from the outdoor part of the house, exits in the vicinity of the indoor unit, and is connected inside the indoor unit.

The indoor unit is provided with an electric parts box inside and leads are extended from the box. A connector is provided at the end of the lead wire, and the end of the F cable extended from the outdoor unit is connected to the connector at a position near the electric component box. Particularly, since the electric component box is disposed at the side end portion inside the indoor unit body, the connector itself is also locked to the side portion inside the body.

[0005]

The electrical connection between the indoor unit and the outdoor unit is made by locking the connector on the side portion in the main body of the indoor unit as described above. There's a problem. That is, since the position of the connector is on the inner side of the main body, every time the F cable and the connector are connected,
Either the front panel constituting the main body is removed or the front panel is left as it is while the hands are inserted into the main body through the small cutouts on the side surface of the main body, which is extremely troublesome and the workability is poor.

The indoor unit may be relocated if necessary, or the wiring between the indoor unit and the outdoor unit is disconnected during maintenance. Even if such a connector separation request is made, it cannot be easily performed because the connector is located inside the indoor unit main body.

If the upper end of the front panel is connected to the indoor unit main body through a hinge mechanism and the front panel is rotated to expose the inside, the connector can be connected.
It is effective in work.

However, since the constituent parts of the hinge mechanism are required and there is an operation for mounting them, the cost effect becomes large. The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to handle a connector very easily without adversely affecting the cost and to improve the wiring workability. To provide an air conditioner.

[0009]

In order to achieve the above object, the separation type air conditioner of the present invention comprises, as a first means, an indoor unit and an outdoor unit, and a wiring extending from the outdoor unit. In an indoor unit that is electrically connected through a connector, the connector is supported by a support tool that can be inserted into and taken out of the indoor unit body.

The supporting means in the first means can be drawn out downward from the lower surface of the indoor unit body, and in this state, the connector is supported so as to be substantially vertical, which is the second means. .

The support in the second means has an opening through which the connection state of the connector can be confirmed when pulled out from the indoor unit body. The support in the second means has a stopper portion that prevents the support itself from moving into the main body of the air conditioner when the connector is connected in a state of being pulled out from the main body of the indoor unit.

The support in the second means has a mounting portion for the thermal fuse. The wiring of the indoor unit in the first means is connected to the electric component in the electric component box through the lead wire from the connector, and the electric component box is the lead wire when the support tool supporting the connector moves. Has a guard part for preventing the deformation and contact with electric parts.

The indoor unit in the first means has a display portion for displaying the operating condition, and the display portion is rotatably supported on the front side of the support and the front panel is removed. By rotating up, the wiring work of the connector can be performed without pulling out the support tool.

[0014]

The above-mentioned connector is supported by a support tool that can be freely taken in and out of the indoor unit main body without removing the front panel constituting the indoor unit, so that the connector is securely supported in the indoor unit main body, and the connector connection is ensured. The separation work can be performed outside the indoor unit body.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Although the separation type air conditioner is composed of an indoor unit and an outdoor unit, the illustration and description thereof are omitted because the outdoor unit has no improvement here.

The indoor unit comprises an indoor unit main body 1 as shown by a chain double-dashed line in the figure. The front panel 2 of the indoor unit body 1 is attached and fixed by a fixture such as a fixing screw, and a hinge mechanism or the like is unnecessary.

However, as will be described later, a part of the panel extending from the lower surface portion to the side surface portion is detachable so that the inside of the main body can be opened and closed. A suction grill 3 is provided on the front panel 2 to guide suction of air in the air-conditioned room into the main body 1.

An outlet 4 is provided on the lower surface of the indoor unit main body 1 to guide the air that has undergone heat exchange in the main body 1 to the air-conditioned room. Inside the indoor unit main body, a heat exchanger, a blower, a drain pan, a blower guide passage, and the like, which are not shown here, are provided.

The indoor unit having such a structure is provided with the display unit 5 on the side of the outlet. The display unit 5 includes a plurality of LEDs (light emitting diodes) on the base plate 6.
7 are arranged side by side in a line, and the corresponding LED emits light in response to an operation on a remote control panel (not shown), and the confirmation of the operation can be obtained.

Mounting legs 8 are integrally provided on the base plate 6 for supporting the LEDs 7 and are connected to an electric parts box 9 arranged in the main body 1. Furthermore,
The mounting leg 8 is provided at one end of the base plate 6, and is pivotally supported by the electrical component box 9 via a pivot pin 10.

At the substantially central portion and the other end portion of the base plate 6,
The support legs 11 and 12 are integrally projected. These support legs 1
The end portions 1 and 12 are brought into contact with a support tool 13 which will be described later, and the display portion 5
The position of is set.

In each figure except FIG. 7, an electric parts box 9 is shown.
The electric component box base 9a which comprises is shown. The mounting leg 8 of the display unit 5 is pivotally supported on the electric component box base 9a, and the support 13 is provided.

The support 13 is composed of a moving guide 14 and a connector base 15. The movement guide 14
Is a plate body having a U-shaped cross-section with an open upper surface, and its upper end is attached to the electric component box base 9a. The lower end is directed diagonally to the back side and is obliquely fixed to the back side as a whole.

Guide holes 16 are formed on both sides of the connector base 15. The guide holes 16 are long holes extending in the longitudinal direction. The pins 17 provided on the upper end of the connector base 15 are engaged with the guide holes 16.

With the pin 17 of the connector base 15 positioned at the upper end of the guide hole 16 of the moving guide 14, both sides of the connector base engage with the moving guide, and the entire connector base overlaps the moving guide.

The connector base 15 is the movement guide 1
It is possible to move along 4. Since the moving guide 14 is fixed, if the connector base 15 is moved, the lower end of the connector base 15 comes out of the moving guide.

However, the connector base 15 is the pin 1 described above.
Since 7 and both side portions are engaged with the moving guide 14, when moving with respect to the moving guide, the posture along the moving guide is maintained, and when it completely projects from this position, gravity acts to make it almost entirely. It will droop vertically.

Each of the connector bases 15 is housed in the indoor unit body 1 in a state where the connector bases 15 are completely overlapped with the movement guides 14, and the connector bases are completely protruded from the movement guides.
In addition, the dimensions are set so that most of the connector base 15 projects from the main body 1 when it hangs vertically.

At this time, as shown in FIG. 5, the panel part 1a of the main body 1 is removed, and a hand is inserted into the main body through the opening formed here, and the connector base 15 is taken in and out. It is ready to work.

In any case, the connector 18 is supported by the connector base 15 and shielded by the connector cover 15a. The connector 18 is an F cable 19 (only shown in FIGS. 1, 2 and 4 and omitted in the other figures), which is a wire extending from the outdoor unit, and the electric component box 9 not shown in the figure. The lead wire 20 connected to the electric component is electrically connected.

To explain further, the lead wire 20 extending from the electric component box 9 is wired from the upper end side of the connector base 15, and the connector 18 is attached and supported at this end portion.
On the other hand, the F cable 19 extending from the outdoor unit is accommodated in the indoor unit body 1 with a sufficient length of allowance.

That is, even if the connector base 15 is projected downward from the lower surface of the indoor unit main body 1, the connector base 15 has a length that allows the connector base 15 to wrap around from the lower end to be connected. An opening 21 is provided at the upper end of the connector base 15, and a window 21a through which the connection state of the connector 18 with the F cable 19 can be visually confirmed can be easily seen from the opening 21.

On the other hand, at the lower end of the moving guide 14,
A stopper portion 22 is provided. This stopper portion 22 is
As shown in FIG. 4, when the connector base 15 is pulled out from the movement guide 14, the upper end portion of the connector base 15 is brought into contact with the connector base 15, and the F cable 19 extended from the outdoor unit is connected to the connector base 15. When the connector base 15 itself is pushed up and connected from the lower end, the connector base 15 itself is prevented from moving.

In particular, as shown in FIG. 6, a mounting portion 24 for mounting and fixing the thermal fuse 23 is provided on the bottom surface of the moving guide 14. The thermal fuse 23 is a small cylinder, and the mounting portion 24 is composed of a space 25 into which the thermal fuse 23 is inserted and a holding claw portion 26 that elastically presses and fixes the thermal fuse in this spatial space. .

In other words, the dimensions are set so that the pressing claw portion 26 elastically presses and fixes the thermal fuse when the thermal fuse 23 is inserted into the space 25.

In a normal state in which the connector base 15 is superposed on the moving guide 14, the thermal fuse 23 at the bottom of the moving guide is superposed on the connector base immediately below the connector 18 via the mounting portion 24. It is only exposed when the is pulled down from the movement guide.

In particular, as shown in FIG. 7, the electric component box 9 is
An opening 27 for inserting a cable is provided on one side surface, from which the lead wire 20 extends to the connector base 15. A printed circuit board 28 is provided at the end of the component box 9 along the opening 27.

A guard portion 29 made of a plate is provided along the side edge of the opening portion 27 facing the printed circuit board 28 at a distance.
Is provided. A cover 30 is provided along the side edge of the electric component box 9 excluding the printed circuit board 28.

With such a side structure of the electric component box 9, the lead wire 20 extending from the inside of the electric component box is in the side surface space of the box 9 surrounded by each cover 30 and the guard portion 29. It has a sufficient length to facilitate the wiring work, so that the lead wire 20 is curved in a loop shape in the space.

This lead wire 20 is connected to the connector base 1 described above.
Even if the lead wire 20 changes its bending state, such as when the lead wire 20 is wired to the connector 5, the lead wire is removed from the connector base 15 for some reason, or the connector base is moved along the moving guide 14, each cover 30 is surely changed. Is within the range of the guard part 29 and the protrusion from here is restricted.

In particular, even if the lead wire 20 moves toward the printed circuit board 28 side and comes into contact with it, the guard portion 29 provided so as to face the board away from the board always prevents the lead wire from contacting the board.

In other words, the electronic component such as a semiconductor element attached to the printed circuit board 28 does not come into contact with the lead wire 20 as long as the guard portion 29 is present, and therefore the electronic component is not destroyed.

The wiring structure of the indoor unit constructed in this way has the following features. (1) The support 13 for supporting the connector 18 is composed of the movement guide 14 and the connector base 15 so that the connector can be freely taken in and out of the indoor unit main body without removing the front panel 2 constituting the indoor unit main body 1. .

Therefore, the work of connecting the connector 18 can be performed outside the indoor unit main body 1, which is very easy and labor-free. (2) The connector base 15 is guided by the movement guide 14 and pulled out downward from the lower surface of the indoor unit body 1. Then, in this state, a substantially vertical drooping state is achieved.

Therefore, even though the indoor unit is usually attached to a high place on the wall surface of the room to be conditioned, it is possible to work on the connector 18 at a lower position, so that the working posture is not overpowered. Moreover, the connector base 15 is in a vertical state and is easy to see. (3) The connector base 15 is provided with an opening 21 through which the connector 18 can be seen.

That is, if the connector base 15 is pulled down from the indoor unit body 1, the connection state of the connector 18 to the parts can be confirmed, and the occurrence of connection failure such as loosening can be reliably prevented. (4) The stopper 22 is provided at the lower end of the moving guide 14.
Since the connector is provided, the end portion of the F cable 19 extended from the outdoor unit is pushed up from below the connector base to lead 20
When connecting to the connector-to-component part at the end portion, the connector base 15 contacts the stopper portion 22 and the connector base does not move upward.

That is, since the stopper portion 22 is provided, the connector base 15 does not move when the connector 18 is connected, and the work is easy. When the connector 18 is connected, the connector cover 15a is attached and the connector base 1
5, the connector base is guided by turning the lower end to the same inclination as the moving guide 14 and pushing up while holding the posture. Finally, the connector base 15 overlaps the moving guide 14 and is housed in the indoor unit body 1. (5) The thermal fuse 23 is provided on the bottom of the moving guide 14.
Since the mounting portion 24 is provided, it is not necessary to separately secure a space for mounting the thermal fuse, and the positional relationship with the connector 18 can be reliably maintained.

Moreover, the thermal fuse 23 is attached to the mounting portion 24.
Since it is elastically pressed and fixed by the pressing claw portion 26 constituting the above, even when the connector base 15 is pulled down, the attached state is maintained. Also, since the thermal fuse 23 can be attached and detached in this state, there is no problem in assembling. (6) Since the guard portion 29 is provided on the lead wire take-out surface of the electric component box 9, even if the lead wire 20 is deformed, the guard portion restricts further movement.

Therefore, the lead wire 20 does not come into contact with the electronic component of the printed circuit board 28, and damage and destruction of the electronic component is prevented in advance. (7) The above-mentioned display portion 5 for displaying the driving status is attached to the support 13
Since it is rotatably supported on the front side, the connector base 15 is exposed by rotating after removing the front panel 2.

Therefore, even when the front panel 2 is taken out of the work without moving the connector base 15, the work of connecting the connector 18 can be performed without removing the electric parts, and the work reliability is improved. Further, since the display unit 5 is positioned on the front side of the support 13, the space is extremely effective. In addition, the present invention can be variously modified without departing from the scope of the invention.

[0051]

As described above, according to the present invention, since the connector is supported by the supporting tool which can be freely taken in and out of the indoor unit body without removing the front panel constituting the indoor unit, the connector can be handled very easily. Therefore, the workability can be improved.
