Description

  The present invention relates to an air conditioner having a plurality of indicator lamps for displaying various states such as an operation state, and in particular, has the indicator lamp on the apparatus main body side and a display window portion on a cover member separate from the main body. It relates to an air conditioner having

In order to display various states such as the operating state of the air conditioner, a technique using a plurality of indicator lights such as LEDs is known. For example, a green LED is turned on during the cooling operation, an orange LED is turned on during the heating operation, or an LED that is turned on according to the wind speed (strong, medium, or weak) is changed. In addition, there is a display that displays a set temperature, a current room temperature, etc. by a 7-segment LED.
Such an air conditioner having a plurality of indicator lamps has a display window portion that transmits each light emitted from each indicator lamp, and displays when the plurality of indicator lamps are turned on simultaneously. If the light that reaches the window interferes with each other, or if light emitted from the lit display lamp leaks into the display window that corresponds to the indicator that is not lit, the visibility of the indicator lamp is reduced and the display state There is a problem that it is misleading.

As a technique for solving such a problem, a technique for dividing the indicator lamps by ribs is known (see, for example, Patent Document 1).
FIG. 10 is a configuration diagram of an air conditioner in which the indicator lamp described in Patent Document 1 is divided by ribs (citing FIGS. 1 to 4 of Patent Document 1). As shown in FIG. 10A, partitioning ribs 17 are integrally formed on the back surface of the decorative plate 12 that allows only the front surface of the display means 2 to pass therethrough. The ribs 17 have a light shielding property, and by pressing the ribs 17 against the circuit board 1, light emitted from the light emitting means 2 can be prevented from leaking, and the above-described misidentification can be prevented.
Here, as shown in FIG. 10B, since the elastic engagement piece 18 is provided on the back surface of the circuit board 1, even if the rib 17 contacts the surface of the circuit board 1, The pressing force is absorbed by the thickness of the elastic engagement piece 18 on the back surface.
Further, as shown in FIGS. 10C and 10D, a technique for attaching an elastic member 16 made of foaming synthetic resin or the like instead of providing the elastic engagement piece 18 on the back surface of the circuit board 1 is also disclosed. Yes.
Japanese Utility Model Publication No. 1-172619

In the above prior art, it is assumed that the ribs 17 are integrally formed on the back surface of the decorative plate 12 (a part of the cover member).
However, in an air conditioner in which display windows 211 to 213 are integrally formed on a display panel 210 that is a part of the cover member 200, for example, an indoor / outdoor integrated air conditioner AC shown in FIG. It is difficult to partition the light emitting means by providing ribs on the back surface of the panel 210.
As illustrated in FIG. 9, when the air conditioner main body 100 is accommodated in a housing 300 and the opening of the housing 300 is covered with a cover member 200 that can be freely opened and closed, the air conditioning Compared with the dimensions of the machine main body 100, the cover member 200, and the housing 300, in order to divide the indicator lamp, which is an extremely small component, by the rib provided on the back surface of the display panel 210, the accuracy is extremely high. This is because design technology is required.
Further, the air conditioner main body 100 is heavy, and the housing 300 that accommodates the air conditioner main body 100 may be deformed, or the display panel 210 may be deformed due to a temperature change or the like. Even if these deformations are very small, as described above, the indicator lamps are extremely small, and it is often impossible to divide them by ribs.
Therefore, a technique is generally known in which the indicator lamps are not divided by ribs provided on the back surface of the display panel 210, but each of the plurality of indicator lamps is individually divided by a light shielding member in advance. . However, in this technique, when there is a gap between the light shielding member and the cover member, there is a problem that light leaks from the gap.
Such a problem comes from the basic structure of the conventional air conditioner in which the air conditioner main body 100 is accommodated in the casing 300 and the front opening of the casing 300 is blocked by the cover member 200. In order to accommodate the large-sized air conditioner main body 100 in the casing 300, accurate positioning dimensions cannot be obtained, and a considerable gap is inevitably generated between the cover member 200 and the air conditioner main body 100. It comes from.
The present invention has been made in view of such circumstances, and an object of the present invention is to cause light leakage in a technique in which each of a plurality of indicator lamps is individually divided by a light shielding member in advance. In order to prevent this, an air conditioner that can prevent the occurrence of a gap between the cover member and the air conditioner main body as described above is provided with a configuration that is as simple and inexpensive as possible.

In order to achieve the above object, the present invention includes an air conditioner main body housed in a casing and a cover member that covers an opening of the casing. A plurality of indicator lamps for displaying various states of the machine, a substrate on which the plurality of indicator lamps are mounted, a light-shielding indicator lamp housing portion to which the substrate is fixed, and each of the plurality of indicator lamps is individually accommodated. The cover member is made of a light-shielding material, and faces each of the plurality of indicator lamps so as to transmit each light emitted from the plurality of indicator lamps when the opening is closed by the cover member. an air conditioner comprising a plurality of display windows which are provided, the indicator housing portion is attached to the slide freely the air conditioner body in the direction perpendicular to the surface of the cover member ,
The indicator lamp housing portion and the cover member are brought into close contact with each other by applying a force in the direction of the cover member directly to the indicator lamp housing portion to urge the indicator lamp housing portion against the cover member. It is comprised as an air conditioner characterized by comprising a means.
As a result, even if there is a gap between the cover member and the indicator lamp housing portion due to design or deformation, the light emitted from the indicator lamp is It is possible to prevent leakage to a display window portion other than the display window portion facing the indicator lamp. Therefore, misrecognition of the display state can be prevented.

The plurality of indicator lamps are respectively housed in the bottoms of a plurality of recesses formed in parallel to the indicator lamp housing part, and the close-contact means includes an opening edge peripheral part of the recess of the display lamp housing part, and the cover The member may be in close contact with the back side surface of the member.
If the indicator lamps are accommodated in the bottoms of the plurality of recesses, and the peripheral edge of the opening end of the recesses and the back side surface of the cover member are in close contact with each other, the above light leakage can be prevented.

Further, the display by the upper Kimitsu contact means causes a magnetic attraction force between the cover member side surface and the indicator lamp housing part side of the surface of the cover member of the indicator housing portion It is desirable if the lamp housing portion is urged against the cover member . This is because it can be configured simply and at low cost.

As described above, according to the present invention, in the technique in which each of the plurality of indicator lamps is individually individually divided by the light shielding member (accommodated in the indicator lamp accommodating part), the indicator lamp accommodating part and the cover member are in close contact with each other. Therefore, each of the plurality of indicator lamps is surrounded by a light-shielding indicator lamp housing portion and a cover member made of the same light-shielding material. As a result, light paths other than the light path toward the display window portion of the light emitted from the plurality of indicator lamps are shielded, so that when the plurality of indicator lamps are turned on at the same time, the lights reaching the display window portion are mutually connected. The display window corresponding to the indicator lamp that is not lit does not leak light emitted from the indicator lamp that is lit, thus preventing misrecognition of the display status and enabling a suitable status display. It becomes.
Since the plurality of indicator lamps are accommodated in the indicator lamp accommodating portion in advance, unlike the prior art in which the ribs are provided on the back surface of the cover member to divide the indicator lamps, high-precision design is not required, and the cover Even when the member or the like is deformed, light leakage can be prevented.
