JP5342476B2 - Air conditioner with display device - Google Patents

Description

  The present invention relates to a display device used for an operation mode display lamp or the like of an air conditioner, and relates to a display device having a structure covered with a translucent plate.

  Conventionally, in this type of air conditioner indoor unit that can be switched to each operation mode of cooling, heating, or dehumidification, an air outlet is formed at the front lower side of the front panel of the indoor unit. A display unit is provided adjacent to the upper right side. This display unit has lamps for airflow, dehumidification, timer, and the like, and an operation lamp. (For example, see Patent Document 1)

  Further, as shown in FIG. 5, a display lamp b is provided on the back surface of the front panel a in the vertical direction, and the distance from the translucent plate d provided on the decorative panel c facing the display lamp b is substantially constant. Therefore, when the lamp is lit, the lamp light projected on the translucent plate d can be seen with substantially the same size.

Japanese Patent No. 3559129

By the way, in this conventional one, there are a large number of parts corresponding to a large number of models, and it is necessary to reduce the cost by sharing the parts and sharing the parts.
In addition, in order to reduce mold costs and design costs, a method for creating a new product is performed by redesigning only the appearance of the decorative panel, etc. When the shape of the decorative panel is changed due to the design change The mounting parts of the display lamps close to the decorative panel were also changed.

  This invention pays attention to this point, and in order to solve the above-mentioned drawbacks, in particular, the configuration is provided with a front panel covering the front side of the casing of the indoor unit, a decorative panel on the front side of the front panel, and a back panel on the back side. A plurality of light emitting elements are positioned, a front panel facing the light emitting elements has a display opening, and a decorative panel facing the opening has a light transmitting plate that transmits and diffuses light from the light emitting elements. In an air conditioner having an operation display device that can be switched to each operation mode of cooling, heating, or dehumidification, and that displays each operation mode on the front surface of the decorative panel, the rear of the translucent plate The decorative panel is formed with a recess, and the recess is provided with a plurality of holes communicating with the light emitting element, and the plurality of light emitting elements are arranged at equal intervals on a straight line in the vertical direction. Corresponds to the lower light emitting element That long distance corresponding to the upper side of the light emitting element than the distance, the width of the recess is obtained by shortening the distance corresponding to the upper side of the light emitting element than the distance corresponding to the light emitting device in the lower side.

  According to the present invention, even if the shape of the decorative panel is changed due to the design change and the distance between the light-transmitting plate and the light emitting element is shifted, the width of the concave portion provided in the decorative panel is adjusted. Mounting parts for light emitting elements close to the panel can be used in common, and the cost can be reduced by this commonization.

The perspective view of one Embodiment of this invention. FIG. The principal part expansion front view. The principal part expanded sectional view. The principal part expanded sectional view of a prior art example.

Next, an air conditioner according to the present invention will be described with reference to an embodiment shown in the drawings. 1 is an indoor unit of a separate type air conditioner, and a main body base 2 and a front panel 3 on the front form a housing, and a heat exchanger (not shown), a blower fan and the like (not shown) are formed in the housing. It has.
The front surface of the front panel 3 is covered with a removable decorative panel 4.

  The front panel 3 is provided with a suction port 5 on the top surface and a blower outlet 6 on the bottom surface, and a pair of left and right air filters (not shown) on the inside of the suction port 5 are provided for the suction air. It removes the contained dust.

  The heat exchanger uses a fin tube type heat exchanger, and acts as an evaporator during cooling operation and becomes a low temperature, and acts as a condenser during heating operation and becomes a high temperature.

  The blower fan is a cross-flow fan and is disposed inside the heat exchanger, and communicates the suction port 5, the air filter, the heat exchanger, and the blower fan to form a blower path (not shown).

  The oval shape on the right side of the air outlet 6 is a receiver 7 of a remote controller (not shown). The user transmits settings necessary for operation / stop of the air conditioner and operation from the remote controller. And the air conditioner is operated.

The decorative panel 4 is made of white ABS resin, and a substantially square black translucent plate 8 is fitted on the lower right side of the decorative panel 4.
The decorative panel 4 on the right rear side of the translucent plate 8 is formed with a vertically long concave portion 9, and further behind the concave portion 9, light emitting elements 10 composed of three light emitting diodes are arranged at regular intervals on a substantially straight line in the vertical direction. The hole 11 is provided in the concave portion 9 provided and facing the light emitting element 10.

  Reference numeral 12 denotes a display substrate, which includes a printed circuit board on which the light emitting element 10 and other electronic components are fixed. A cover 13 is provided around the light emitting element 10 to prevent leakage of light emitted in a cylindrical shape. . The display substrate 12 is fixed to components connected to the main body base 2 side.

  The distance from the tip of the light emitting element 10 to the surface of the light transmitting plate 8 is such that the distance A corresponding to the upper light emitting element 10a is 1.2 times larger than the distance B corresponding to the intermediate light emitting element 10b. Since B is at a position 1.2 times larger than the distance C corresponding to the lower light emitting element 10c, the light transmitting area to the light transmitting plate 8 increases as it goes upward, and the light appearance is also increased. In order to prevent the concave portion 9 from becoming larger as it goes, the width D, E, and F of the concave portion 9 is made smaller as it goes upward, so that the spread of light is suppressed and the visible size of the upper and lower three light emitting elements 10 is uniform. The width dimension D corresponding to the upper light emitting element 10a is 0.9 times smaller than the width dimension E corresponding to the intermediate light emitting element 10b, and this dimension E corresponds to the lower light emitting element 10c. The width dimension F is 0.9 times smaller than the width dimension F.

  Even if the shape of the decorative panel 4 is changed due to the design change and the distance between the translucent plate 8 and the light emitting element 10 is shifted, the decorative panel can be adjusted by adjusting the width dimension of the recess 9 provided in the decorative panel 4. The attachment parts of the light emitting element 10 adjacent to the common can be used in common, and the cost can be reduced by the common use.
