Description

Integrated drain fan unit of evaporator unit for bus air conditioner

The present invention relates to an integrated drain pan unit (DRAIN PAN UNIT) supporting the left and right evaporator in the air conditioner unit (EVAPORATOR UNIT) mounted on the roof of the bus.

In general, a bus air conditioner (AIR CONDITIONER) mounted on the roof of the bus is usually composed of a condenser unit (CONDENSER UNIT) and an evaporator unit, the condenser unit serves to convert the high-temperature gas refrigerant compressed in the compressor into a liquid refrigerant The evaporator unit acts to cool the air by taking the heat from the air by cooling the refrigerant gas liquefied in the condenser unit to a low pressure state by an expansion valve, and then supply the cooled air as a blower to the room. To do.

In addition, the bus air conditioner is manufactured according to different types of buses produced by automobile manufacturers, so that the outer case and the cover of the condenser unit and the evaporator unit are made of FRP (glass fiber reinforced plastic) which is easy to manufacture a mold.

In the case of the evaporator unit, as well as the outer case and the cover, the drain pan unit mounted therein is also made of FRP. The drain pan unit of the prior art has a left drain pan 100a as shown in FIGS. 4 and 5. ) And the right drain pan 100b are manufactured.

The reason for manufacturing the drain pan unit by separating the left and right as described above is to install the evaporator 200a, 200b on the left and right side of the evaporator unit in order to be able to supply to the air passages installed on both sides of the ceiling of the bus. This is because the drains are formed by the structures of the passages 301a and 301b formed on both sides of the outer case 300 of the evaporator unit so as to smoothly supply air cooled by the left and right evaporators to the air passages installed on both sides of the ceiling. Fans 100a and 100b are installed at the left and right sides, and the left and right drain pans 100a and 100b are condensate pools 101a for collecting condensate generated by both evaporators 200a and 200b. Since the 101b must be provided close to the passages 301a and 301b, the left and right drain pans of the drain pan unit are manufactured in a symmetrical state.

However, since the drain pans 100a and 100b are separated and manufactured to the left and the right as in the related art, the following problems are followed when installing the evaporator unit.

That is, the left and right drain pans 100a and 100b have condensate pools 101a and 101b formed in a symmetrical state so that the case of changing the installation position does not occur while the left and right drain pans are not generated. If the left and right drain pans are not installed correctly and are installed in a different position, they may cause a problem of degrading the performance of the evaporator unit. Since the right drain pan (100a) (100b) is installed separately, there is also a problem that the installation work is slowed to increase the number of work.

The present invention has been devised in view of the conventional problems, and means for manufacturing the left and right drain pans integrally mounted on the outer case of the evaporator unit so that the left and right drain pans can be always arranged in a aligned state. It was designed for the purpose.

The present invention as a means for achieving the above object,

In the installation of the drain pan unit formed by separating the left and right drain pans formed in the symmetrical state with the condensate pools from each other in the outer case of the evaporator unit,

It is characterized in that it is configured to be integrally formed with a connecting portion connecting the left and right drain pans and one side of the left and right drain pans so that an air inlet is formed between the left and right drain pans of the drain pan unit.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of an installation state for explaining the present invention, FIG. 2 is a perspective view of a drain pan unit that is a main part of the present invention, and FIG. 3 is a cross-sectional view of the drain pan unit that is a main part of the present invention.

Reference numeral 1 denotes a drain pan unit, in which the left and right drain pans 2 and 3 are integrally formed by the connecting portion 4.

Since the connecting portion 4 connecting the left and right drain pans 2 and 3 of the drain pan unit 1 is formed according to an accurate design, air formed between the left and right drain pans 2 and 3 is formed. The spacing of the intake port 5 can be maintained accurately.

The left and right drain pans 2 and 3 are formed with condensate pools 21 and 31 for receiving condensate generated by evaporators 6a and 6b installed therein, and the condensate pool 21 At least one drain nipple 7 is attached to each one of the heads 31.

On both sides of the left and right drain pans 2 and 3, support members 22 and 32 for fixing the evaporators 6a and 6b are formed, respectively.

In addition, reference numeral 8 denotes an outer case of the evaporator unit mounted on the bus roof, and the drain pan unit 1 is installed inside the outer case 8.

In addition, both sides of the drain pan unit 1 are provided with a brore 9a, 9b for supplying air cooled by the evaporators 6a, 6b to an air passage formed inside the ceiling of the bus. The supply hoses (9a) and (9b) are provided in the passages 81 and 82 formed on both sides of the outer case 8, and the hoses connected to the drain nipples 7 in the passages 81 and 82 described above. 71 is piped and is comprised so that condensate may be discharged | emitted to the exterior through a chassis.

The operation of the present invention configured as described above will be described.

Since the left and right drain pans 2 and 3 of the drain pan unit 1 are integrally formed by the connecting portion 4, the left and right drain pan units 1 are installed when the drain pan unit 1 is installed in the outer case 8. Even if only one part of the drain pans (2) and (3) is assembled at the correct position, the left and right drain pans (2) and (3) can be installed accurately in an aligned state, which facilitates the installation work of the drain pan. There is this.

In addition, since the air inlet 5 formed in the middle of the drain pan unit 1 is maintained at the correct interval according to the design, the air inlet 5 is installed at the correct position only by installing the drain pan unit 1. It becomes possible.

Therefore, both side evaporators 6a and 6b installed in the left and right drain pans 2 and 3 of the drain pan unit 1 can be installed in accordance with the design. The supply of cool air is smooth and the cooling efficiency can be expected to be improved.

According to the present invention as described above, since the left and right drain pans constituting the drain pan unit installed inside the outer case of the evaporator unit are integrally connected by the connecting portion, only one portion of the left and right drain pans is in position. Even if it is assembled, both drain pans can be installed in the aligned state, so that the drain pan unit can be installed in the correct position, and the effect of making the installation work easy and quick can be expected. Since the drain pan unit is installed in accordance with the design of the evaporator, the evaporator can be efficiently cooled and operated. The drain pan unit is connected to the left and right drain pans to facilitate transport and storage. It is a practical design that provides advantages.
