2. Description of the Related Art Conventionally, in an air conditioner, as a countermeasure against dew condensation at an air outlet of an indoor unit, for example, a protruding portion that protrudes obliquely forward is provided at the lower edge of the air outlet, and the presence of the overhanging portion causes the An invention in which air is drawn in is disclosed (for example, see Patent Document 1).
Japanese Utility Model Publication No. 5-3836 (page 5-7, FIG. 1)

However, the air conditioner disclosed in Patent Document 1 has no countermeasure against dripping of condensed water in a portion located below the front end of the fan casing in the lower part of the blowout port of the indoor unit. There was a problem that water dropped into the room from the mounting portion of the front grille (corresponding to the design panel).
That is, when the condensed water generated at the end of the fan casing drops on the design panel at the screw fixing part (lower part of the air outlet) that fixes the design panel to the main body, the condensed water is generated between the screw cover and the screw fixing part of the design panel. It penetrated and dropped from the screw fixing portion to the outside of the indoor unit.

  The present invention has been made to solve the above-described problems, and is an air conditioner that can prevent dew condensation from dripping from a screw fixing portion that fixes a design panel to a main body at a lower portion of an outlet of an indoor unit. You will get a chance.

An air conditioner according to the present invention includes a main body,
A design panel installed on the front surface of the main body and having an open outlet;
A heat exchanger for cooling indoor air, an air blower for sucking indoor air and sending out indoor air cooled in the heat exchanger, and the cooled air sent by the air blower. A fan casing for guiding indoor air to the air outlet;
An air conditioner having an indoor unit comprising:
A vertically extending casing vertical portion formed at a position close to the back surface by a predetermined distance from a protruding casing end portion on the front side of the fan casing is formed at the edge of the lower portion of the blowout port on the front side of the design panel. Along with the panel vertical part protruding upward, it is fixed to the main body by a fixing bolt,
A flange formed on an upper edge of the panel vertical portion covers the fixing bolt, and the casing terminal portion protrudes more to the front side than the front end portion of the flange .

  Therefore, in the air conditioner according to the present invention, the condensed water generated on the lower surface of the casing end portion is guided by the capillary phenomenon through the gap between the lower surface of the casing end portion and the upper surface of the flange. It is possible to prevent the condensed water from dripping. Therefore, the cleanliness and comfort of the indoor unit of the air conditioner are improved.

[Embodiment 1]
1 to 4 illustrate an air conditioner according to Embodiment 1 of the present invention. FIG. 1 is an exploded perspective view, FIG. 2 is a sectional view, and FIG. 3 is a detailed perspective view of a screw fixing portion A. 4 shows a sectional view of the screw fixing portion A. FIG.
1 to 4, a design panel 2 is installed on the front surface of a main body 1 of an indoor unit of an air conditioner 100 that air-conditions indoor air, and an air outlet 9 is formed below the design panel 2. A heat exchanger 5 that exchanges heat (cools or heats) with room air and a blower 6 that blows room air are arranged inside the main body 1, and the heat-exchanged air is guided to the fan casing 7. The air is blown into the room through the air outlet 9.

The design panel 2 is fixed to the main body 1 with fixing screws 3 at the air outlet 9, and the fixing screws 3 are covered with a screw cover 4.
The end portion 7 a of the fan casing 7 protrudes from the front surface in a “<-shape (the same as a horizontal V shape)” in a side view, and a dew condensation generation portion 8 is formed on the lower surface side thereof. A casing vertical portion 7b is formed below. A casing fixing hole or fixing notch 7c through which the fixing screw 3 passes is formed in the casing vertical portion 7b.
The design panel 2 includes a panel bottom plate 2a, a panel vertical portion 2b rising substantially vertically on the front surface of the panel bottom plate 2a, a panel fixing hole 2c through which a fixing screw 3 formed in the panel vertical portion 2b passes, and a panel vertical portion 2b and a flange 10 projecting in a hook shape forward from the upper edge of 2b.
Note that a range including the panel vertical portion 2b (provided at the air outlet 9) is referred to as a “screw fixing portion A”. That is, the screw fixing portion A is formed by fixing the fixing screw 3 passing through the panel fixing hole 2c of the design panel 2 and the casing fixing hole or fixing notch 7c of the fan casing 7 to the main body 1, thereby fixing the screw. 3, the design panel 2, and the fan casing 7 are fixed to the main body 1, and a screw cover 4 is installed on the front side of the fixing screw 3.

Next, the operation will be described.
In the main body 1 of the air conditioner configured as described above, when the power is turned on, the blower 6 is driven, the indoor air is sucked into the main body, passes through the heat exchanger 5, and the fan casing 7 is moved. As a result, the air is blown into the room through the air outlet 9 of the design panel 2.
At this time, the design panel 2 is fixed to the main body 1 with a screw 3 at the lower part of the air outlet 9 and covered with a screw cover 4 having a shape similar to that of the air outlet 9 of the design panel 2 so that the screw 3 cannot be seen to improve the appearance. It has been broken. Further, the flange 10 of the design panel 2 has a shape along the head shape of the screw 3.

In the dew condensation generating part 8 formed at the end of the fan casing 7, dew condensation occurs because the cold and dry air heat-exchanged by the heat exchanger 5 is mixed with the warm and humid air in the room. Condensed water that has condensed on the dew generation part 8 guides the gap between the dew generation part 8 and the flange 10 of the design panel 2 adjacent to the dew generation part 8, and further the gap between the panel vertical part 10b and the casing vertical part 7b by capillary action. Then, it flows into the condensed water recovery part 2d of the panel bottom plate 7a of the design panel 2 (indicated by an arrow in FIG. 4).
For this reason, dripping of dew condensation water from the screw fixing part A to the outside of the main body 1 can be prevented.
Further, since the design panel 2 is provided with the flange 10, the strength of the screw fixing portion A can be increased (more precisely, the rigidity of the panel vertical portion 2 b can be improved), and handling during assembly is facilitated. Yes.
Furthermore, since the flange 10 of the design panel 2 has a shape along the head shape of the screw 3, the fixing screw 3 is guided, and the screw tightening workability is facilitated.
