Description

[Detailed description of the invention] The present invention relates to a condensed water treatment device for a local air conditioner, in which condensed water condensed on an evaporator is sprinkled on a condenser,
To provide a dew condensation water treatment device for a local air conditioner, which reduces accumulation in a drain tank by evaporating the condensed water that cannot be completely evaporated in a condenser and leading it to a drain tank without performing this drainage work as much as possible. The purpose is to

As shown in Fig. 1, in the conventional local air conditioner, when the refrigerant is used, the condensed water in the evaporator 1 is sprinkled into the condenser 5 through the hole 4 of the upper drain pan part 3 which also serves as the partition plate 2, and converted into heat of condensation. Only the condensed water that cannot be completely evaporated is led to the drain tank 6 and drained periodically, which has the disadvantage of requiring a lot of draining when the humidity is high, which is time-consuming.
In addition, in an air conditioner equipped with a refrigeration cycle, a plurality of evaporation trays are provided around the compressor, and the condensed water generated in the evaporator is evaporated by the heat of the compressor. It is also being considered to install another evaporation dish that evaporates the water using the heat of a pipe that passes high-temperature, high-pressure refrigerant, or a silencer, etc.; Therefore, it took time for the entire condensed water collected in the evaporating dish to rise to the evaporation temperature.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 2 to 4.

As shown in the figure, an air outlet 10 is provided above the frame 8 of the local air conditioner, an evaporator 11 is provided inside, and an upper drain pan section 12 is provided below the evaporator 11, which also serves as a partition plate 13. ing. The upper drain pan section 12 is formed with a hole 15 for sprinkling condensed water on the evaporator 11, and the front surface of the frame 8 is provided with an inlet 16 for the evaporator 11 and a condenser 14. A suction port 17 is provided for use. A blower 19 and a compressor 31 are housed in a flow path 18 for discharging heat from the condenser 14, and a hot air outlet 20 is provided at an end of the flow path 18. A lower drain pan section 21 is provided below the condenser 14. A vertically long heating pipe 22 provided on the side of the lower drain pan section 21 includes a pipe 23 that becomes a part of the high-pressure discharge pipe from the compressor 31 and a part of a pipe 24 that becomes an outgoing pipe to the condenser 14. It is provided as a heating part 25, and forms a reservoir of condensed water between it and the heating pipe 22. The heating pipe 22 is provided with a connection port 28 for the rubber hose 26, and the connection port 28 is located below the middle end of the lower drain pan 21, so that there is a lot of condensed water that cannot be completely evaporated in the heating pipe 22. Only then will water be drained into the drain tank from this connection port 28. A blower 29 for blowing cold air is installed behind the evaporator 1, and the frame 8 is mounted on a cart 30 that can be moved freely.
It is installed in.

In the above configuration, when the local air conditioner is operated, the cold air cooled by the evaporator 11 is discharged from the air outlet 10 by the blower 29 and cooled, while the heat of the condenser 14 is transferred to the outside of the machine from the hot air outlet 20 by the air blower 19. released. On the other hand, the condensed water that has condensed on the evaporator 11 is dripped onto the condenser 14 from the hole 15 provided in the drain pan part 12, and the condensed water that has not completely evaporated in the condenser 14 is dripped on the lower drain pan 21. The dropped condensed water flows into the heating pipe 22. At this time, the high temperature refrigerant discharged from the compressor 31 passes through the heating section 25,
The condensed water that has flowed into the heating pipe 22 is heated and evaporated while it accumulates in the vertically elongated heating pipe 22.
Since the volume formed between the heating pipe 22 and the inner periphery of the heating pipe 22, that is, the volume in which condensed water accumulates, is small, the condensed water flowing into the heating pipe 22 is quickly evaporated by the heat of the high-temperature heating section 25. Note that when the condensed water has not completely evaporated, it is led to the drain tank 27 from the connection port 28 via the hose 26.

In this invention, the heating pipe in which condensed water collects is formed vertically so as to surround the heating section heated by high-temperature refrigerant, so that the condensed water flowing into the heating pipe is sequentially evaporated and drained into the drain tank. The amount of condensed water flowing into the drain tank is significantly reduced, and the effort required to periodically drain the water in the drain tank is reduced.
