[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for blowing heat exchanged air into a room to cool and heat the room.

[0002]

2. Description of the Related Art As such an air conditioner, an air conditioner in which a refrigerant is circulated through a heat exchanger disposed in a room, room air is passed through the heat exchanger, and the temperature of the room air is adjusted by heat exchange. Is common.

In such an air conditioner, indoor air is taken in from an air inlet, passed through a heat exchanger, and then blows out the air after heat exchange from an air outlet formed in an air blowing frame. The air blowing frame is provided with a wind direction changing plate (hereinafter, referred to as a louver) for guiding the blowing air in order to change the direction of the blowing air to be blown indoors to a desired direction.

There are two types of louvers in the air conditioner: a manual louver type in which the position of the louver is manually changed, and an automatic louver type in which the position of the louver is changed by a motor. Different types were used depending on whether they were louver specifications or auto louver specifications.

Holes 43f and 43g through which 5b are inserted are formed, so that the bosses 45a and 45b for shaft stoppers are released so as not to be buffered.

As described above, the bosses 45a and 45b for the shaft stopper plates and the boss 46 for fixing the motor base are provided on one end 41a of the blowout frame.
a and 46b are provided so that the blowing frame 41
By simply attaching any one of the shaft stopper plate 44 and the motor mounting base 43 without changing the configuration of the louver 12, the manual specification or the automatic louver specification can be easily achieved. Note that, in FIG.
Is a heat insulating material.

Next, a guide plate 51 which guides the drain pan upon receiving the drop of dew on the pipe surface and the surface of the heat insulating material during cooling will be described with reference to FIGS.
In FIG. 7, the guide plate 51 is indicated by hatching for convenience.

At the lower end of the above-mentioned heat exchanger 2, a drain pan 50 for receiving the dew water of the heat exchanger is arranged. In this embodiment, the drain pan 50 is a tube sheet 2a of the heat exchanger 2.
Is extended to below the flow rate variable valve 6 on the side of. On the other hand, the refrigerant pipes (refrigerant inlet pipe and refrigerant outlet pipe) 4a connected to the heat exchanger 2 are arranged above the heat exchange unit and outside the drain pan. A heat insulating material 4b is wound around the refrigerant pipe, and the condensed water condensed on the refrigerant pipe 4a is transmitted through or leaks through the heat insulating material 4b.
Condensation may also form on the surface.

In this embodiment, a variable flow rate valve 6 located below the refrigerant pipe 4a and a guide plate 51 for receiving dew condensation water that has fallen into the motor section 52 are arranged.

The guide plate 51 is made of a resin material, for example,
It is preferable that the sheet is formed by bending a sheet of vinyl chloride, polyester, or the like. By forming the sheet from such a material, the degree of freedom in bending and molding is high, and processing is facilitated.

Although the shape of the guide plate 51 is not particularly limited, it is preferable that the guide plate 51 receives the falling dew and engages with a pipe or the like in the heat exchange unit to be stopped. In the present embodiment, as shown in FIGS.
And a tube 6a connected thereto. Specifically, the motor cushion rubber 5 attached to the motor 52
3, a screw hole 51a, which is screwed together with 3, a variable flow valve 6
Similarly, it is formed in a circular groove shape so as to be locked by the first locking portion 51b in the shape of a circular groove engaged and locked between the motor and the motor 52 and the pipe 6a connected to the variable flow valve 6. A second locking portion 51c is provided. Since the guide member 51 has a configuration having the screw hole 51a, the first locking portion 51b, and the second locking portion 51c, the guide member 51 can be inserted and fixed from the front of the heat exchange unit, so that the guide member 51 is always visually observed from the front. It can be installed and removed easily. As shown in FIG. 8, the guide plate 51 is disposed so as to cover the fan motor 55.

The guide plate 51 has wall surfaces 51e and 51e.
The sheet is bent into a substantially V-shape by f, receives dew water in a gutter shape by the bottom surface 51h, and drops the dew water onto the drain pan 50 along the hanging surface 51k.
In addition, the bottom surface 51h is inclined so that the hanging surface 51k faces downward, and guides water received by gravity.

Next, the operation of this embodiment will be described.

In this embodiment, when performing indoor air conditioning, first, a desired room temperature is set, the heat exchange unit 1 is turned on, and the fan 1 of the heat exchange unit 1 is turned on.
By operating 0, the refrigerant is guided to the heat exchanger 2 through the refrigerant pipe 4 or the hot water is guided through the hot water pipe 5. The heat exchange between the heat exchanger 2 and the indoor air sucked from the suction port 3 is performed, and the air is blown into the room from the blowout port 11 by the fan 10 to perform the air conditioning of the room.

At the time of manufacturing or assembling the air conditioner according to the present embodiment, in the case of manual specification of the louver, as shown in FIG. 5, one end 41a of the blowing frame 41 is attached to the bosses 45a, 45b for the shaft stopper plates. The fixing plate 44 is attached by fixing the screw 48. At this time, the shaft hole 44c is slidably fitted with the louver shaft 12a.

On the other hand, in the case of the auto louver specification, the same one as the blowout frame 41 is shared. As shown in FIG. 5, after attaching the motor 13 to the motor mount 43 with the screws 42, the motor mount 43 is fixed to the motor fixing bosses 46a, 46b with the screw 49.

As described above, the blowout frame 41 can be used for both the manual specification and the automatic louver specification, and the automatic louver specification or the manual specification can be achieved by attaching the shaft stopper plate 44 or the motor base mounting base 43. it can. Therefore, when manufacturing according to each specification, the manufacturing is easy, and the manufacturing cost can be reduced.
On the other hand, during the cooling operation of the air conditioner, the refrigerant pipe 4a
And the dew passing through the heat insulating material 4b may increase and fall. Since the dew water is located away from the drain pan 50, the dew water may fall off the drain pan 50 as it is, leaking out of the air conditioner, and dripping into the room. However, the condensed water of the refrigerant pipe 4a and the condensed water leaking to the surface of the heat insulating material 4b are received by the guide plate 51 and transmitted through the hanging portion 51k to form the drain pan 5d.
Fall towards zero. Accordingly, it is possible to prevent the dew condensation water such as the refrigerant pipe from falling into the room, or to reduce the size of the drain pan 50 to a necessary minimum. Moreover, as shown in FIG. 8, the guide 51 plate is provided so as to cover the fan motor 55, so that it is possible to prevent water from entering the fan motor 55 and the like that dislike water.

The present invention is not limited to the above-described embodiments, but can be variously modified without departing from the gist of the present invention.
