Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner of a house wall-embedded type (built-in type) in which an indoor unit and an outdoor unit are integrated.

[0002]

2. Description of the Related Art Conventionally, in a built-in type air conditioner, there is only one indoor side air outlet, and cold air and warm air are also blown out from this air outlet.

For this reason, when the mounting position of the air conditioner is set to the upper part, the outlet is located in the upper part of the room, and the warm air during heating becomes
When the air conditioner was attached to the lower part from the upper part, and conversely, the cool air for cooling was supposed to be blown out from the lower part.

For this reason, the air outlet is one in the equipment for both heating and cooling.
In the case of a place, an air direction switching plate is provided as a means for switching the direction of cold air and warm air, and during cooling, with respect to the air outlet,
The wind direction switching plate is made horizontal so that the cold air blows sideways, and at the time of heating, the wind direction switching plate is turned downward so that the hot air blows downward.

[0005]

As described above, even if the direction of the cold air and the hot air is switched by the air flow direction switching plate, the height of the air outlet is constant, so that a comfortable cooling and heating effect cannot be obtained.

[0006]

In order to solve the above-mentioned problems, the present invention integrates an indoor unit and an indoor unit, and forms an indoor air passage by an indoor air guide and an outdoor air passage by an outdoor air guide. In an air conditioner for both air conditioning and heating, the evaporator of the indoor unit is installed in the center of the indoor side, the upper outlet for blowing cold air is provided in the upper part, and the lower outlet for blowing warm air is provided in the lower part. A fan for cold air is provided near the outlet, and a fan for warm air is provided near the lower outlet, and during cooling operation, cold air is switched to the evaporator, the fan for cold air, and the upper air passage that passes through the upper outlet, and during heating operation. Is provided with a rotatable partition plate for switching the hot air to the evaporator, the hot air fan, and the lower air passage that passes through the lower air outlet.

A motor for automatically reciprocating the partition plate is provided.

Further, when the partition plate is reciprocally rotated,
If the indoor blower guide is provided with an abutting portion where the partition plate and the indoor blower guide come into contact with each other, air leakage during blowing is hindered.

[0009]

[Function] A dedicated air path for cold air and hot air is formed, and the cool air is blown from the upper outlet during the cooling operation and the hot air is blown from the lower outlet during the heating operation.

Further, switching can be automatically controlled by controlling the reciprocating rotation of the partition plate with a motor.

Further, air leakage can be prevented by bringing the partition plate into contact with the indoor air guide when switching the partition plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.
FIG. 1 is a vertical sectional view of an air conditioner of the present invention, and FIG. 2 is an external view of the partition plate.

On the indoor side of the air conditioner 1, an evaporator 6 is provided at the center.
, The upper outlet air conditioner 4 on the upper part, and the lower outlet 7 on the lower part.
have. A cool air fan 5 is provided near the inside of the upper outlet 4, and a warm air fan 8 is provided near the inside of the lower outlet 7. These are rotated by a motor (not shown).

Reference numeral 9 is a partition plate for switching the direction of air flow, and a rotary shaft 15 is integrally provided with the partition plate 9 at the center of the partition plate 9. Both ends of the rotary shaft 15 are rotatably supported by the blower guide 2, and a motor 16 for rotating the partition plate 9 has a rotary shaft 1
It is attached to one end of 5. The blower guide 2 is bent in the shape of a central foil, and when the partition plate 9 rotates,
The upper half 2a of the air blow guide 2 and the upper half 9a of the partition plate 9 are in contact with each other (state (a) in FIG. 1), and the lower half 2b of the dogleg shape of the partition plate 9 and the lower half of the partition plate 9 are in contact with each other. 9b and 9b (the state of FIG. 1B) is attached.

Further, when the partition plate 9 is rotated, the upper and lower tips are integrally formed with the blower guide 2 and come into contact with the shield plates 2c and 2d located above and below the evaporator 6, respectively. When the plate 9 rotates in the clockwise direction, the air passage 10 is formed, and when it rotates counterclockwise, the air passage 11 is formed.

3 is an outdoor air blowing guide, 14 is an outdoor air outlet, and 12 is a condenser. An outdoor air blowing fan 13 forms an air passage 17 through which the outside air is blown out from the outdoor air outlet 14 through the condenser 12. .

The partition plate 9 is controlled by a switch provided on the main body 1 (not shown) or a remote control device when the air conditioner main body 1 is in operation, and the motor 16 is controlled to rotate clockwise in FIG. The plate 9 is switched to a, and the motor 16 is controlled to rotate counterclockwise during heating,
The partition plate 9 is switched to B.

Further, the cooling fan 5 is controlled to rotate during cooling, and the heating fan 8 is controlled to rotate during heating.

Next, the operation of the partition plate 9 and the air flow path in the operation of the air conditioner body 1 of the present invention will be described. Since the operations of the evaporator 6 and the condenser 12 are well known, detailed description thereof will be omitted.

When the cooling operation is turned on, the temperature, the air volume, etc. are input by a switch or a remote control device (not shown) during the cooling operation, the motor 16 rotates to switch the partition plate 9 to the state shown in FIG. Fan 5 for rotation,
When the air in the room is sucked in and passes through the evaporator 6, the heat of the air is transferred and cooled, and the cool air is blown out from the upper outlet 4 to cool the room.

On the other hand, during the heating operation, when the heating operation is turned on, the temperature, the air volume, etc. are input by a switch or a remote control device (not shown), the motor 16 rotates in the opposite direction to that in the cooling operation, and the partition plate 9 is shown in FIG. When the heating fan 8 is rotated and the room air is sucked in and passes through the evaporator 6, the air is heated by the heat of the evaporator 6 to be warmed,
Warm air is blown out from the lower outlet 7.

The upper outlet 4 and the lower outlet 7
It goes without saying that a more comfortable cooling and heating effect can be obtained by making the angle of the louver provided in the adjustable.

[0023]

The present invention configured as described above has the following effects. Air outlets are provided in the upper and lower parts of the air conditioner main body, and cool air is blown from the upper outlet during cooling and warm air from the lower outlet during heating. It provides more comfortable air conditioning than air conditioning using blown air. In addition, it is not necessary to adjust the angle of the louver provided at the air outlet during cooling and heating.

Further, by controlling the reciprocating rotation of the partition plate by the motor, it is possible to automatically control during the cooling and heating operation. Furthermore, when the partition plate is switched, the partition plate and the indoor blower guide are brought into contact with each other, so that air leakage from the respective ventilation paths can be prevented.
