Description

[Detailed Description of the Invention] The present invention relates to a separate air conditioner, and particularly to improvements to its indoor unit.

This type of indoor unit is equipped with a service valve for the refrigerant circuit used for air purge, refrigerant charging, etc. However, if the service valve is exposed outside the unit, it may cause incorrect operation of the service valve during operation. There is a risk that it will become impossible. In order to eliminate this risk, it is possible to install it within the unit, but it requires rational placement of the service valve, and
There was a problem in that it was not easy to check the position of the service valve depending on the location where it was installed, and it was not easy to check the position after the installation work was completed.

The present invention has been developed in view of this problem, and one embodiment of the invention will be described below with reference to the drawings. In Figs. 1 and 2, 1 is an indoor unit of a separate type air conditioner, which has an inlet 2 formed on the front and side surfaces of the upper part of the main unit, and an outlet 3 formed on the front, respectively. Indoor air is cooled by an indoor heat exchanger 5 that functions as an evaporator, and then blown out from an outlet 3 to cool the room. 6
is an electrical equipment box, 7 is a dew pan that receives dew generated by the indoor heat exchanger 5, 8 is a drain tank provided below the electrical equipment box 6 to receive dew water drained from the dew pan 7, and 9 is a refrigerant Compressor, 10, 10 is a refrigerant circuit service valve that is opened and closed during air purge work, refrigerant filling, etc., 11 is a removable auxiliary unit provided below the drain tank 8 and above the service valves 10, 10. It is a dew pan made of transparent synthetic resin material, and has service valves 10, 10.
It has a protrusion 11a into which it fits. Therefore, the auxiliary dew pan 11 is positioned by the engagement between the protrusion 11a and the valves 10, 10, and when the removable main body front plate 1a is removed and the drain tank 8 is removed, the auxiliary dew pan 11 can be removed without removing it. The open and close states of the service valves 10, 10 and the attachment and detachment states of the valve caps can be confirmed.

The present invention is constructed as described above, and the service valves 10, 10 are rationally arranged within the unit body so that they can be used for positioning the auxiliary dew pan 11, and there is no possibility that the valves 10, 10 may malfunction during operation. In addition, since the auxiliary dew pan 11 is transparent, it is possible to check whether the lubricating oil mixed with the refrigerant gas is leaking from the service valves 10, 10 by removing the drain tank 8. It can be easily confirmed through the dew pan 11, and even if dew water drips from the cooler 5 while removing the drain tank 8 and discarding the dew water in this tank, it will be caught by the dew pan 11, and The accumulated dew water can be easily disposed of by removing the dew pan 11.
