[0010]
In the present invention, the guide rib for attaching / detaching the air filter provided on the saddle is arranged at a position facing the reinforcing bar of the air filter, and the guide rib and the reinforcing bar of the air filter overlap each other. Increase can be prevented.
[0011]
In addition, the present invention is provided with a holding portion for holding an accessory such as an air purifier by notching a part of the guide rib, and it is not necessary to provide a separate part for holding the cost. I can hold it down.
[0012]
Further, the present invention is such that the distance between the guide ribs is smaller as it is closer to the center, and the airflow resistance due to the guide ribs is greater at the center of the heat exchanger and less at both ends. Exchange capacity can be increased.
[0013]
【Example】
An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view when the air conditioner body 1 is installed in a living room. FIG. 2 is a plan view of FIG. 1 viewed from the A direction. 3 is a cross-sectional view taken along line BB in FIG. The air conditioner main body 1 has a substantially fan-shaped horizontal section, is closely attached to the ceiling of the living room and the corners of the walls in two directions, has a suction port below, and has a blow-out port 2 in the arc portion. doing. When the cross-flow fan 3 rotates and blows air, the air is sucked from the front grille 4 which is a lower suction port, and heat is exchanged via a plurality of heat exchangers 6 to form an arc-shaped blower port. Air flows to 2 and blows.
[0014]
5 is a water tray for treating the condensed water of the heat exchanger 6, 7 is a trough for treating the condensed water dripping from the heat exchanger 6 in the inclined portion and guiding it to the water tray 5, 8 is an internal connection pipe, and 9 is the wind direction The change device 10 is an air filter provided between a front grill 4 provided below and serving as a suction port and a water tray 5 for treating condensed water in the heat exchanger 6. A guide rib 7 a that becomes a guide when the air filter 10 is attached and detached is integrally provided so as to be orthogonal to the flange 7. For this reason, although the air filter 10 is substantially L-shaped and has a large area that covers the heat exchanger 6, the eaves 7, and the water tray 5, the air filter 10 is inserted along the guide rib 7 a. As a result, the air filter is not caught on the way or does not enter the fixing groove 12 for fixing the both side surfaces of the air filter 10 provided in the main body 1, and the air filter attaching / detaching work becomes easy. Further, instead of newly providing the guide rib 7a, by integrally forming the guide rib 7a on the flange 7, the ventilation resistance can be minimized, and the cost increase can be suppressed.
[0015]
A second embodiment of the present invention will be described with reference to FIG. 4 is a BB cross-sectional perspective view of the air conditioner of FIG. The same components as those shown in FIG. Reference numeral 10a denotes a reinforcing bar of the air filter 10, and the air filter 10 having a large area maintains its shape by arranging the reinforcing bars 10a in a vertical and horizontal grid pattern. By providing the guide ribs 7a provided on the flange 7 relative to the longitudinal reinforcing bars 10a of the air filter 10, the guide ribs 7a are not attached to the mesh portion of the air filter 10 when the air filter 10 is attached or detached. The air filter 16 comes into contact with the vertical reinforcing bar 10a and slides and is guided, so that the air filter 16 can be attached and detached more easily and more reliably without being caught. Thereby, not only cleaning of the air filter 10 and maintenance of the air conditioner 1 can be easily performed, but also the ventilation resistance can be reduced by arranging the vertical reinforcing bars 10a and the guide ribs 7a in a straight line.
[0016]
A third embodiment of the present invention will be described with reference to FIG. 5 is a cross-sectional view taken along line BB in FIG. The same components as those shown in FIG. 11 is an air purifying filter having an air purifying function, and 7b is an air purifying filter mounting frame portion provided on the flange 7. The air purifying filter mounting frame portion 7b has a shape in which a part of the guide rib 7a is notched. It can be mounted simply by inserting the air purifying filter 11 into. The air purifying filter mounting frame portion 7b is not newly provided but is formed by cutting out the guide rib 7b integrally formed with the flange 7, so that an air purifying function can be added without increasing the ventilation resistance. Yes, cost increase can be suppressed.
[0017]
A fourth embodiment of the present invention will be described with reference to FIG. 6 is a BB cross-sectional perspective view of the air conditioner of FIG. The same components as those shown in FIG. The arrangement interval L of the guide ribs 7a provided on the flange 7 is narrower toward the center of the flange 7 and is wider toward the ends. That is, since the flange 7 is configured in parallel with the heat exchanger 6 and the cross flow fan 3, the longitudinal center of the flange 7 is the center of the heat exchanger 6 and the center of the cross flow fan 3. Since the wind mainly flows in the central part of the conventional heat exchanger 6 and the wind speed falls as it approaches both ends, the guide rib 7a is provided in the central part where the air volume is large. By adjusting the ventilation resistance in the longitudinal direction of the heat exchanger 6 so that only a minimum is provided at both ends, the wind speed distribution can be improved and the heat exchanger capacity can be enhanced.
[0018]
【The invention's effect】
As is apparent from the above embodiment, the present invention improves the workability when inserting the air filter by providing the rib with a guide rib for attaching and detaching the air filter.
[0019]
Further, by disposing the guide rib opposite to the vertical reinforcing bar of the air filter, the workability is further improved and the ventilation resistance is not increased.
[0020]
Further, by providing the air purifying filter mounting frame portion integrally with the bag, it is possible to add a function of air cleaning with a minimum ventilation resistance and to suppress an increase in cost.
[0021]
Moreover, the air velocity distribution can be improved and the heat exchanger ability can be enhanced by arranging the guide ribs at the time of attaching / detaching the air filter to be narrower toward the center of the ridge and wider toward the both ends.
