Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of an air conditioner, and more particularly to an improvement of a blower casing.

[Conventional technology]

FIG. 5 is a perspective view showing a conventional air conditioner of this kind,
1 is an exterior panel, 2 is an underframe, 3 is a hermetic refrigerant compressor, 4
Is a condenser for condensing and liquefying a high-temperature and high-pressure gas refrigerant, 5 is a fan for blowing air to the condenser 4 to cool it, 6 is a cooler for evaporating the liquid refrigerant, and 7 is a sirocco fan for cooling the cooler 6. , 8 is a motor for rotating and driving the sirocco fan 7 and the fan 5, 9 is a partition plate for supporting the motor 8 and partitioning the exterior panel 1 into two chambers, a cooler 6 side and a condenser 4 side. , 10 accommodates the sirocco fan 7 and encloses the sirocco fan 7 in an eccentric state, and 11 indicates a suction plate in which an opening of the spiral plate 10 on the cooler 6 side is closed to form a suction port 11a. , 12 are refrigerant pipes, and 13 are outlets for cooling air.

FIG. 6 is an exploded perspective view of the blower casing A including the partition plate 9, the spiral plate 10, and the suction plate 11, the sirocco fan 7 and the motor 8, and 21 is the spiral plate. A plurality of bent protruding ears formed by bending both edges of 10 at the right angle to the outside, and the suction plate 11 is inserted into the screw hole 21a of each protruding ear 21.
The suction plate 11 is fixed to the edge of the spiral plate 10 by screwing a plurality of mounting screws 22 inserted into the through holes 11b. In FIG. 6, the other partition plate 9 is the same as the suction plate 11 in the same manner as the spiral plate 10.
Needless to say, it is fixed to the edge of the condenser 4 so as to close the opening on the side of the condenser 4.

[Problems to be solved by the device]

Since the blower casing in the conventional air conditioner is configured as described above, on both edges of the spiral plate 10,
Not only is the process of forming a large number of bent tabs 21 having screw holes 21a for fixing the suction plate 11 and the partition plate 9 extremely troublesome, but also the suction plates are attached to both edges of the spiral plate 10. 11
The work of positioning the suction plate 11 and the partition plate 9 when fixing the partition plate 9 and the partition plate 9 with the mounting screw 22 was difficult, resulting in poor work efficiency.

The present invention has been made to solve the above problems, and includes a suction plate 11 and a partition plate 9 of a blower casing A.
On the spiral plate 10 for fixing the
It is not necessary to form a large number of bent lugs 21 having a,
Moreover, it is an object of the present invention to provide an air conditioner which facilitates the positioning work of the suction plate 11 and the partition plate 9 on the spiral plate 10 and improves the efficiency of the assembly work of the blower casing.

[Means for Solving the Problems]

The blower casing A of the air conditioner according to the present invention is provided with a plurality of tongue pieces protruding in the same direction on both edges of the spirally wound plate, and a suction plate and a partition plate for closing both side openings of the spirally wound plate. Each of the tongue pieces is twisted after being inserted, and a slot is formed to fix the suction plate and the partition plate at a predetermined position of the spiral plate.

[Action]

According to this invention, the tongue formed on the edge of the spiral plate,
By inserting a plurality of slots formed in the suction plate and the partition plate and then twisting the tongue, the suction plate and the partition plate are fixed at predetermined positions on the spiral plate.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing a blower casing of an air conditioner according to an embodiment of the present invention. In FIG. 1, the same reference numerals as those of the conventional one shown in FIG. Omit it.

In the figure, 31 is a plurality of tongue pieces provided so as to project on both sides of the spiral plate 10, 32 is a suction plate 11 and a partition plate 9 for closing the openings on both sides of the spiral plate 10, respectively. Each of the above tongues
After inserting the tongue piece 31 into each of the slots 32 with a plurality of slots formed corresponding to 31, the each tongue piece 31 is indicated by the arrow shown in FIG. 3 by the pinching tool 33 as shown in FIG. Suction plate 11 by twisting a predetermined angle (about 45 °) in the direction
The partition plate 9 is fixed at a predetermined position on the spiral plate 10 as shown in FIG.

[Effect of device]

As described above, according to the present invention, a plurality of tongues are provided on both edges of the spiral plate, and the tongues are provided on the suction plate and the partition plate that respectively close the openings on both sides of the spiral plate. After being inserted, it is twisted to form a plurality of slots that fix the suction plate and the partition plate in place on the spiral plate, so that the suction plate and the partition plate of the blower casing are fixed by the mounting screws. It is not necessary to provide a large number of bending tabs with screw holes on the spiral wound plate
Moreover, the work of positioning the suction plate and the partition plate on the spiral plate becomes extremely easy, the efficiency of the work for assembling the casing for the blower is significantly improved, and it has an excellent practical effect that contributes to cost reduction.
