Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to an air conditioner, and particularly to a structural improvement of a separate indoor unit.

(Technical background of the invention and its problems) An indoor unit in a seven-inch rate air conditioner has conventionally been configured as shown in FIG.

That is, a suction port 2 equipped with a filter (not shown) is provided at the upper front surface of the main body 1, and an outlet port 3 is provided at the bottom thereof.

A heat exchanger 4 is disposed within the main body 1 facing the suction port 2, and a blower 5 equipped with a cross-flow fan is disposed diagonally below the heat exchanger 4.

Note that a heat insulating material 6 is provided on the inside of the back surface of the main body 1, which also serves as a ventilation guide path.

By driving the blower 5, the air in the conditioned room is guided in the order of the suction port 2, the heat exchanger 4, the blower 5, and the outlet 3 as shown by the arrow in the figure, and is again led out to the conditioned room. It is now possible to do so.

The air introduced into the suction port 2 immediately passes through the heat exchanger 4 as shown in FIG.
heat exchanger 4.
It is necessary to insulate all subsequent parts along the air guide path to take adequate measures against condensation, and to ensure that the seal is completely and securely sealed to prevent cold air leakage.

Therefore, the labor and costs are unavoidable.

Furthermore, the blower 5 has poor suction characteristics because the heat exchanger 4 is disposed on the suction side, and the blower 5 and the heat exchanger 4 must be opposed in the depth direction of the main body 1 in order to improve the blowing efficiency.

Also, the winding start part 7 and the nose part 8, which affect the blower characteristics.
7! are formed by a part of the heat insulating material 6 and the drain plug 4a, respectively. Jζ These end up facing each other in the depth direction of the main body 1.

Therefore, the depth dimension of the main body 1 has been reduced, and problems have arisen to the extent that it is no longer possible to achieve a thinner structure.

(Object of the Invention) The present invention has been made with attention to the above-mentioned origin, and its purpose is to set the blower, heat exchanger, and air flow path arranged in the main body in an optimal state. The present invention aims to provide an air conditioner that improves air blowing efficiency, reduces costs, and allows the main body to be made thinner.

(Summary of the Invention) The present invention includes a main body, an inlet and an outlet provided on the front surface of the main body, a blower disposed in the main body opposite to the inlet, and a blower disposed in the main body opposite to the outlet. a heat exchanger disposed as a blower, a back plate of a main body constituting a casing of the blower, and a partition made of a heat insulating material inserted to partition the air outlet and the suction port and serving also as the nose of the blower. It is characterized by comprising a board.

(Embodiment of the Invention) An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, 11 is the main body of the indoor unit of the air conditioner.

The main body 11 is formed into a thin rectangular shape, and a suction port 12 having a large area is provided at the upper part of the front surface.

A filter 12a is removably attached to the suction port 12.

A blowout port 13 equipped with a looper 13a is provided below the suction port 12.

A control panel 14 equipped with electrical components (not shown) is provided on the side of the suction port 12, and is electrically connected to a remote control panel 15 provided separately from the main body 11.

Further, inside the main body 11, a blower 16 including a cross-flow fan 16a and a heat exchanger 17 are arranged.

The cross-flow fan 16a of the blower 16 faces the suction port 12 in the depth direction and along the top thereof.

Further, the heat exchanger 17 is arranged below the blower 16 and is inclined diagonally to the front side, and its upper part faces in the depth direction of the suction port 12 and along the lower part thereof.

The lower portion of the heat exchanger 17 faces the blow-off port 13 in the depth direction and extends further downward.

Between the blower 16 and the heat exchanger 17 is a horizontal piece 18a of a partition plate 18 made of a heat insulating material and having a cross-sectional shape.
intervenes.

The vertical piece 18b of the partition plate 18 connects the suction port 12 and the heat exchanger 17.
intervening between.

The lower end of the heat exchanger 17 is a drain pan 1 that also serves as a partition plate.
Listed on 9.

From the gap 20 between the drain pan 19 and the bottom surface of the main body 11, electrical wiring, a drain hose, and a heat exchanger 17 (not shown) are connected.
A refrigerant pipe or the like that communicates with the outdoor unit is inserted through it.

By driving the blower 16, the air in the air-conditioned room flows from the suction port 12 to the main body 11 as shown by the arrow in the figure.
introduced into the world.

Then, an air flow path S can be formed in which the air blower 16, the heat exchanger 17, and the air outlet 13 are guided in this order, and the air is blown from the air outlet 13 back into the air-conditioned room.

Note that the winding start portion 21, which affects the air blowing characteristics, is not curved at the upper end of the back plate 11a of the main body 11, and the horizontal piece portion 18a of the partition plate 18 serves as the nose portion 22.

Therefore, the winding start portion 21 and the nose portion 22 face each other in the vertical direction.

The air conditioner constructed in this manner operates as described below.

That is, by starting the refrigeration cycle operation and driving the blower 16, the air in the air-conditioned room is guided along the blowing passage S.

On the way, the air passes through a heat exchanger 17 and exchanges heat therewith, and is converted into cold air, for example.

Therefore, this cooling effect is achieved by introducing cold air into the air-conditioned room.

Note that within the main body 11, cold air is conducted only in a section from the heat exchanger 17 to the outlet 13, and only air before heat exchange is conducted to other parts, but no cold air is conducted.

Since the distance between the heat exchanger 17 and the air outlet 13 is very short, the insulation structure and sealing structure are very simple.

Furthermore, since there is only the suction port 12 on the suction side of the blower 16, there is little resistance, and since the winding start portion 21 and the nose portion 22 are vertically opposed to each other, the air flows smoothly and has good multi-air blowing efficiency.

Further, as described above, since the casing including the winding start portion 21 and the like is bent by the back plate 11a, there is no need to provide a separate casing, and variations in air blowing performance can be reduced.

That is, conventionally, the casing was formed separately from a foam material and simply fitted inside the main body.

For this reason, the air blowing passage was deformed due to variations during assembly, resulting in variations in air blowing performance.

In this embodiment, there is no need to provide a separate casing, and this problem can also be solved.

In addition, since the partition plate 18 also serves as the nose, the number of parts is reduced, and since the partition plate is made of a heat insulating material, there is no possibility of condensation forming on the surface of the partition plate that the air comes into contact with before cooling. .

(Effect of the invention) As described above, the present invention provides the following effects.

(1) Since the heat exchanger is placed downstream of the blower, the amount of insulation material can be significantly reduced.

(2) Since the casing of the blower is constructed from the back plate of the main body, there is no need to provide a separate casing, and variations in blowing performance are also reduced.

(3) The number of parts is reduced because the partition plate also serves as the nose.

(4) Since the partition plate is made of a heat insulating material, it is possible to prevent dew condensation on the surface that comes into contact with the air before cooling.
