Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an air conditioner that is mounted at a high location on an indoor wall.

(B) Prior Art An example of the structure of an outer casing of an air conditioner that is mounted at a high place on an indoor wall is disclosed in Japanese Utility Model Publication No. 57-54499.

According to this content, a discharge port is provided in the lower part of the front surface of the outer casing, and a suction port is provided in the upper part. This suction port is provided with a large number of horizontal bars to form a suction portion, and the horizontal bars extend to a blind portion on the side of the suction port. In this blank section, the front surface between the horizontal bars extended in the vertical direction.

(c) Problems to be solved by the invention When such an air conditioner is mounted on an indoor wall, the front surface between the horizontal bars of the blind section becomes approximately parallel to the indoor wall.

Therefore, the light from the lighting equipment and the light reflected from the ceiling that enters between the horizontal bars of the air intake part of the outer box of this air conditioner,
Although it does not enter the inside of the machine through the ventilation holes between the horizontal bars, there is a risk that light that enters between the horizontal bars of the blind section may hit the front of the blind section and cause it to shine. In this way, if the space between the horizontal bars of the suction part does not shine and the space between the horizontal bars of the blind part shines, there is a risk that it may be unsightly to the user. In order to eliminate this unsightly appearance, it is possible to add a grain to the surface between the horizontal bars of the blank area, but if the grain is rough, the light that hits this surface will be reflected diffusely, making it look white. There is a risk that this may occur.

The purpose of the present invention is to make the spaces between the horizontal bars of the suction part and the spaces between the horizontal bars of the blind part look approximately the same.

(d) Means for solving the problem In order to achieve this object, the present invention is such that the front surface between the horizontal bars of the blind part is inclined diagonally downward.

(E) Function When light hits the slope between many horizontal bars, this light hits the top surface of the lower horizontal bar, preventing the light reflected from this slope from being reflected in the direction of the user. I have to.

(F) Embodiment In FIG. 1, reference numeral 1 denotes an indoor heat exchange unit of a separate air conditioner, which is installed at a relatively high position on an indoor wall surface 3 near a ceiling 2. 4 is the outer casing of this heat exchange unit, which is molded from plastic. A heat exchanger, a blower, etc. are housed inside this outer box. Reference numeral 5 denotes an air outlet formed at the lower front of the outer box, and a wind direction changing plate 6 is disposed in the air outlet 5. Reference numeral 7 denotes a horizontal bar formed above the air outlet 5 of the outer case, and is formed over almost the entire width of the outer case 4 from the left end to the right end. As shown in FIG. 2, a ventilation opening 8 is provided between the horizontal bars on the left side of the outer casing 4, and this portion serves as a suction opening 9. In FIG. 2, the vertical dimension a of this horizontal bar 7 is
2.0mm, and the gap dimension b between horizontal bars 7 is 5.0mm.
Reference numeral 9 denotes an air filter disposed on the back side of the ventilation opening 8, which is inserted into and taken out from an insertion opening (not shown) between the lowermost horizontal beam and the air outlet 5.

10 is the guide rail of this air filter 9,
It extends vertically on the back side of the outer casing 4.

Further, the left and right sides of the horizontal crosspiece 7 of this outer casing 4 are blind portions 11 and 12. This blind part 1
As shown in Figures 3 and 4, the shapes of numbers 1 and 12 are such that the vertical dimension c of the horizontal bar 7 is 2.0 mm, the depth dimension d is 3.0 mm, the gap dimension e between the horizontal bars 7 is 5.0 mm, and this blind part is formed. The diagonally downward angle f of the front surface 13 is 20°, and the thickness dimension g of the outer box is 6.0 mm.

When the heat exchange unit 1 equipped with the outer box having such a shape is installed on the indoor wall surface 3, the blank parts 11, 1
2, the illumination light from the ceiling 2 hits the front surface 13 diagonally downward as shown by the solid line arrow in FIG. Therefore, when the user looks up at the heat exchange unit 1 from below, the blind parts 11, 12
The obliquely downward facing front surface 13 rarely appears shiny. Furthermore, there is little possibility that the light that has entered between the horizontal bars 7 of the suction section 9 will enter the interior of the machine through the ventilation opening 8 and appear to be shining.

(g) Effects of the invention As stated above, the present invention forms a large number of horizontal bars on the front surface of the outer casing, provides ventilation holes between these horizontal bars, uses this part as a suction part, and uses this part as a suction part. The front surface between the horizontal bars connecting from the top is tilted diagonally downward,
This part was made into a blind part. In this way, the space between the horizontal bars of the blank section is made less shiny, giving the appearance that the horizontal bars extend horizontally from the suction section to the blank section, giving the exterior of the air conditioner a sleek appearance. Obtainable.
