Abstract

PURPOSE:To provide an air-conditioner which is easy to use and easy to install by providing a drain changeover part in a drain channel which lead condensed water produced at an evaporator to a drain tank, wherein the changeover part has a movable drain passage which selectively discharge the condensed water to the drain tank or to the outside of a main case. CONSTITUTION:A drain tank 21 for storing condensed water, which is produced when the air is cooled at an evaporator 8, is provided in a lower section of a main case 6. A changeover part 48 provided in a drain channel 40, which leads condensed water falling to a receiving dish 35 to the tank 21, comprises a water receiving tank 43 and a movable drain passage 49 which receives the condensed water from a receiving dish drain cylinder 42 and selectively changes over the drain passage to the tank 43 or to the outside of the case 6. When a door 51 is opened, a water outlet 55 of the passage 49 protrudes outwardly from the case 6 to enable continuous drainage of the condensed water, whereas when the door is closed, the passage 49 comes into the case 6 to allow the condensed water to flow into the tank 43, from where the water flows through a pipe 46 and is stored in the tank 21.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application The present invention relates to an air conditioner in which a refrigeration cycle consisting of a compressor, an evaporator, a condenser, etc., a drainage tank, a blower, etc. are provided in the main body case.

(b) Conventional technology An air conditioner that has a refrigeration cycle consisting of a compressor, an evaporator, a condenser, etc., a blower, etc. as a single unit in a main body case is disclosed in, for example, Japanese Unexamined Patent Publication No. 12305/1982. has been done. In this prior art, dew water generated in the evaporator is collected in a dew tank and led to a water tank inside the main body case, or to a cooling water tank for cooling the condenser.

However, in models that use a water tank, it is necessary to stop operation when the water tank becomes full with dew water, while in models that lead cooling water to a tank, there is a hose for water supply and a hose for drainage. This has the disadvantage of limiting the installation location.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and has a simple structure that allows switching between draining water to a water tank and continuous draining, and the following. To provide an air conditioner that is easy to use and install.

(d) Means for Solving the Problems In order to solve the above problems, the air conditioner of the present invention includes a refrigeration cycle consisting of a compressor, an evaporator, a condenser, etc., a drainage tank, and a blower inside the main body case. In the air conditioner, a drainage switching section that can drain the dew water to the outside of the main body case is provided in the middle of a drainage passage that leads dew water generated in the evaporator to the drainage tank, and the switching section is configured to switch the dew water away from the dew water. The present invention is characterized by having a movable drainage channel for selectively draining water into the drainage tank and outside the main body case.

Further, the main body case is provided with an opening that faces the movable drainage channel, and a door body for opening and closing the opening, and the movable drainage channel is integrally formed on the back surface of the door body. It's okay.

(E) Function With the above configuration, when the movable drainage channel is housed in the main body case, dew water drained from the movable drainage channel passes through the drainage channel and is drained into the drainage tank. On the other hand, if the movable distribution channel is protruded from the opening of the main body case, the dew water distributed from the rotary distribution channel is continuously drained to the outside of the main body case. In this way, it is possible to switch between drainage of dew water to the drainage tank and continuous drainage by simply moving the movable drainage channel.

Here, when the door body (51) is open, dew water is continuously drained from the rotating drainage channel (49) via the hose (56) or directly into a bucket or the like.

On the other hand, when the door body (51) is blocked, dew water falls from the rotary drainage channel (49) into the water receiving tank (43), and flows from the drain pipe (44) along the gutter-like drainage channel (45). It falls into the drain tank (21) through the drain pipe (46) and accumulates in the drain tank (21).

In addition, since the dew water flowing down the side end plate (8a) of the evaporator (8) is smoothly guided into the dew water receiving tray (35) due to the presence of the protrusion (38), the dew water generated in the evaporator (8) All of the water falls into the dew water tray (35) and does not spill out from the tray (35), so the cooling fan (1) bottom plate (5
) and the installation floor surface will not leak due to dew water, and the cooling fan (1)
can be used comfortably.

Furthermore, FIGS. 9 to 11 relate to other embodiments.
