There is installed a stopper which loads an opening end 200a of the front cover when the cover 300 is opened, and what is more, which is fitted into and engaged with the opening end 200a so as to prevent the cover from being closed. The substantially C-shaped groove 330 of the fitting unit 310 is opened in the direction in which a groove width extends when the stopper 310a is loaded on the opening end 200a.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an opening / closing lid provided on a front cover of an indoor unit.

[0002]

2. Description of the Related Art Generally, a pin is provided on a front cover of an indoor unit, and a lid portion provided on the front cover is provided with a fitting portion that fits the pin. The open / close lid of the front cover of the harmony machine is known.

[0003]

In this type, the opening / closing lid of the front cover is opened, and the inter-unit cable from the outdoor unit is connected to the connector of the indoor unit facing it. However, conventionally, there is no stopper in this lid, and there is a problem that the lid is closed when the inter-unit cable is connected. In order to solve this, it is conceivable to provide a stopper, but there is a problem that the lid cannot be opened and closed smoothly by providing the stopper.

Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a stopper on the lid,
Another object of the present invention is to provide an opening / closing lid for a front cover of an air conditioner that can smoothly open and close the lid.

[0005]

In order to achieve the above object, the present invention provides a pin on a front cover of an indoor unit, and a cover body provided on the front cover has a substantially C-shape fitted to the pin. A fitting part having a groove is provided, and when the lid is opened, a stopper is provided that rides on the opening edge of the front cover and fits inside the opening edge to prevent the lid from closing. The substantially C-shaped groove of the fitting portion is characterized in that when the stopper rides on the opening edge portion, it opens in a direction in which the groove width widens.

[0006]

According to the present invention, after the lid is opened, the stopper fitted inside the opening edge functions, so that the lid is closed unless it is forcibly closed. There is no such thing. Moreover, when the stopper rides on the opening edge portion of the front cover, the groove width of the fitting portion widens, so that the pin is not excessively applied and the lid is smoothly opened and closed.

[0007]

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a so-called domestic air conditioner, and shows a sectional structure of an indoor unit 1. As is well known, the indoor unit 1 includes a heat exchanger 5, a drain pan 7, a blower 9, and the like.

The indoor unit 1 is provided with a front panel 11 which will be described in detail later, and the suction port 1 of the front panel 11 is provided.
3, and the air sucked from the suction port 17 of the upper panel 15 passes through the heat exchanger 5, the blower 9, etc., as shown by the arrow in FIG.
Blown out from. In addition, a horizontal blade 21 for guiding the air blowing direction in the vertical direction is provided in the air outlet 19.
Longitudinal blades 23 for guiding in the left-right direction are provided.

As shown in FIG. 2, the front panel 11 is opened and closed so as to flip upward with respect to the upper end.

That is, the front panel 11 is provided with three brackets 100 in the depth direction of FIG. It is hooked on the pin 103 (FIG. 2) provided on the upper part of the cover.

To hook these holes 101 on the pins 103, the front panel 11 is pushed toward the front cover. Then, the pin 103 hits the bracket 100, and the pin 103 bends the bracket 100 laterally.

When this is pushed further in, the pin 103 fits into the hole 101 of the bracket 100, and the bracket 10
0 restores the original state. As a result, the hole 101 is caught in the pin 103.

3 and 4 show the essential parts of this embodiment.

In FIG. 3, reference numeral 200 denotes a front cover of the indoor unit 1, and an opening / closing lid 300 is provided at the right end of the front cover 200 in the figure.

The opening / closing lid 300 is opened when the inter-unit cable is connected after the indoor unit 1 is installed. When the opening / closing lid 300 is opened, a connector (for connecting the inter-unit cable) is provided there. (Not shown)
Is facing.

When connecting the cables between the units, the opening / closing lid 300 is opened, but in the conventional case, the opening / closing lid 300 may be closed at the time of connection.

Therefore, in this embodiment, the following measures are taken so that the opening / closing lid 300 is not easily closed during the work of connecting the cables between the units.

That is, referring to FIG. 4, the front cover 200 of the indoor unit 1 is provided with a pin 210 having an elliptical cross section, and the lid 300 provided on the front cover 200 is provided with:
A fitting portion 310 that fits into the pin 210 is provided.

The fitting portions 310 are integrally provided at both ends of the upper portion of the lid 300, and have substantially C-shaped grooves 330 that fit into the pins 210.

Then, as shown in FIG. 4a, the front cover 2
When the lid 300 is gradually opened from the state of being attached to 00, the stopper 310a first rides on the opening edge portion 200a of the front cover 200 as shown in FIG. 4b, and as shown in FIG. 4c. And the opening edge 200
Fit inside a.

According to this, after the lid 300 is opened, the stopper 3 fitted inside the opening edge portion 200a.
Since 10a works, this lid 300 will not close unless it is forced to close it. According to this, using the part 310a of the fitting part 310,
Since the stopper function is provided there, it is possible to prevent the lid 300 from falling down easily and at low cost.

Further, according to this embodiment, when the stopper 310a rides on the opening edge portion 200a of the front cover 200, as shown by the arrow in FIG.
A force is applied to the 0 stopper 310a. Then, in the fitting portion 310, as shown by the dotted line, the groove 3 having a substantially C-shape is formed.
The groove width of 30 automatically expands.

According to this, since no excessive force acts on the pin 210, the front cover 200 can be opened and closed smoothly.

This lid 300 is shown in FIG.
It can be hooked inside the front panel 11, as shown in FIG. If this is hooked, the front panel 11 will not be closed, and the work of connecting the inter-unit cables can be performed with confidence.

In short, according to this embodiment, when the stopper 310a rides on the opening edge 200a of the front cover 200, the groove width of the C-shaped groove 330 is automatically widened, so that excessive force is applied to the pin 210. Does not work, and the front cover 200 can be opened and closed smoothly.

Although the present invention has been described based on the embodiment, the present invention is not limited to this. For example, although there are two fitting portions 300 in the above embodiment, the number of fitting portions 300 is not limited to this, and there may be a plurality of fitting portions.

[0028]

As is apparent from the above description, according to the present invention, since the stopper fitted inside the opening edge portion functions after the lid is opened, the lid is forced. It does not close unless you explicitly close it.
Therefore, the work of connecting the cables between the units can be performed with confidence. Moreover, when the stopper rides on the opening edge of the front cover, the groove width of the fitting portion widens,
The lid is opened and closed smoothly without applying excessive force to the pin.
