Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner that includes a cooler, a dew receiver provided below the cooler, and a blower provided on the leeward side of the cooler.

Conventionally, in this type of air conditioner, dew condenses on the outer wall of the casing of the blower.

It is also known to fix a dew guide gutter to the outer wall of the blower casing in order to guide this dew to the dew receiver, but dew penetrates into the minute gap between the casing and the gutter due to capillary action. There was a problem with the inside of the plane getting dirty.

It is also known to paste insulation material on the outer wall of the blower casing to prevent condensation, but if the thickness of the insulation material is thin, condensation cannot be prevented in times of high humidity. When the thickness is increased, there is a problem in that it becomes difficult to attach the insulation to the casing and the insulation material is easily peeled off.

The present invention has been developed in view of such problems, and one embodiment thereof will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an indoor unit of a separate air conditioner, in which a heat exchange chamber 2, an electrical equipment and drain tank chamber 3, and a compressor chamber 4 are arranged above and below in a vertically rectangular parallelepiped body.

The heat exchange chamber 2 has an air outlet 5 and an inlet 6 on the left and right sides in its front side, an inlet (not shown) in the side, and a cross section facing the binocular inlets for evaporation. A letter-shaped cooler 7 is arranged, a dew receiver 9 is fixed below the cooler 7 on the dish-shaped bottom plate 8 of the heat exchange chamber 2, and the air outlet 5 is opened from the leeward side of the cooler 7.
As a result, the casing 10a of the close flow type blower 10
, 10b are installed vertically, and a fan 10c driven by an electric motor 10b fixed on the bottom plate 8 is built in the casing.

11 is an air filter.

As shown in FIGS. 2 to 4, the tube plate 7a of the cooler 7 is placed at both ends of the metal casing 10a. A is fixed to support the cooler 7 on the bottom plate 8, and a gutter 11 having a generally U-shaped cross section and extending from side to side with one end facing above the dew receiver 9 is attached to the outer wall of the casing 10a with a rising piece on the side of the casing. 11a is welded and fixed.

Then, on the outer wall 10a of the casing above the gutter 11, a thin impermeable heat insulating material 1 with a thickness that can prevent dew condensation at standard times is provided.
2 (for example, closed-cell foamed polyethylene, foamed rubber, etc.), and its lower end 12a is attached to the rising piece 11a of the gutter 11.
It is polymerized at the upper end and its surface side.

Therefore, even if dew condenses on the surface of the heat insulating material 12 during high humidity, the dew falls into the gutter 11 without entering the minute gap between the gutter 11 and the casing 10a, and is guided into the dew receiver 9 through the gutter 11.

In addition, the rising piece 11a is formed so that the opposite casing of the gutter 11 is higher than the side rising piece 11b, so that the insulation material 1
This makes it easier to attach the lower end of 2.

Further, a thick heat insulating material 13 is attached to the outer wall 10a of the casing below the gutter 11.

Further, an electrical equipment box 14 is disposed in the upper part of the electrical equipment and drain tank room 3, and a removable exposure plate is provided below the electrical equipment box 14 on a soundproof wall 15 that also serves as a partition wall from the compressor room 4. A saucer 16 is placed, and a drain tank chamber 17 is placed on the dew saucer 16.

A dew port 17a is formed on the upper surface of the drain tank 17, and the dew generated in the cooler 7 is introduced into the tank 17 through a drain hose 18 extending from the dew container 9. When the inside becomes full of water, a built-in float 19 operates a microswitch 20 inside the electrical box 14 to stop air conditioning operation.

A compressor 21 is built into the compressor chamber 4, and a main body front plate 2 is attached to the main body front plate 2, which is detachably mounted on the lower front surface of the electrical equipment and drain tank chamber 3.
2 is provided.

Reference numeral 23 designates one of a pair of valves used for air purging of the indoor unit and connecting piping when the indoor unit is connected to the outdoor unit (not shown).

As described above, the present invention includes a cooler, a dew receiver provided below the cooler, and a blower provided on the leeward side of the cooler, with one end facing above the dew receiver and a cross section extending from left to right. A U-shaped gutter is fixed to the outer wall of the casing of the blower,
Since the impermeable heat insulating material is attached to the outer wall of the casing so that the lower end overlaps with the upper end of the rising piece on the casing side of the gutter and its surface side, the wall thickness of the heat insulating material can be made thinner. In addition, dew that condenses on the surface of the insulation material when it is humid is guided through the gutter to the dew receptor without penetrating the gap between the gutter and the casing, so there is no risk of contaminating the inside of the machine. big.
