DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a configuration of an indoor ventilation circuit of a separate type air conditioner of a heat pump for cooling and heating.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional indoor unit of a separate type air conditioner is mounted on a wall in a living room so as to protrude therefrom. The configuration was composed of, in order from the windward side, a front grille 4, a heat exchanger 3, a once-through blower 2 surrounded by a casing 21 and a stabilizer 20, and a vertical wind direction changing device 6. By rotating the once-through blower 2 with the motor, a blowing action is generated, and the air flows through as described by the arrows in the above-described order, thereby performing cooling / heating / dehumidification.

[0003]

However, since the indoor unit of the separate type air conditioner having the above structure is installed so as to protrude from the wall of the room, it gives a feeling of oppression to the room and fuses with the interior. Has limitations. Furthermore, since it is installed on one wall, even if the wind direction changing device is used, the air conditioning temperature distribution in the living room becomes uneven, and there is a problem in terms of comfort.

[0004]

In order to solve the above-mentioned problems, a fan-shaped trapezoid-shaped indoor-side ventilation circuit having a suction port below and a discharge port at a part of an arc-shaped side wall is provided with a windward side.
Heat exchanger, once-through blower, stabilizer in order from the side
Provided is a separate type air conditioner characterized in that:

Another object of the present invention is to provide a separate type air conditioner in which a substantially triangular electric box is provided at a triangular corner between the rear casing and the outer case.

[0006]

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A room-side ventilation circuit in the shape of a quarter-arc fan shaped trapezoid that is attached in close contact with the ceiling in the living room and the corners of the two walls, has a suction port below, and has a discharge port in the arc. is there. When the once-through blower is rotating and blowing,
Inhale air from the front grill, which is the suction port downward,
Downstream, the air flows sequentially to a heat exchanger, a once-through blower surrounded by a stabilizer and a rear casing, and an arc-shaped outlet. Thus, since it is installed in the corner of the living room, there is no feeling of oppression and the integration with the interior is better. In addition, since the air is blown out from the quarter-arc-shaped outlet at a wide angle, there is no temperature unevenness in the indoor air conditioning, and the comfort is more excellent.

In addition, since a substantially triangular-shaped electrical box is provided at a triangular corner portion between the rear casing and the outer box, it can contribute to downsizing of the indoor unit and is excellent in integration with the interior.

【Example】

(Embodiment 1) A first embodiment of the present invention will be described below with reference to FIGS.
-It will be described with reference to FIGS.

FIG. 1 is a perspective view when an indoor unit of a separate type air conditioner of the present invention is installed in a living room.

FIG. 2 is a plan view of FIG. 1 viewed from the direction A. FIG. 3A is a cross-sectional view of the BB. FIG.
It is CC sectional drawing.

A quarter-circular fan-shaped trapezoidal room which is attached in close contact with the ceiling of the living room and the corners of the two walls, has a suction port below, and has a blow-out port 6a at the arc. In the machine 1, the front grill 4 which is the suction port below
A heat exchanger 3 held in turn by a water receiving tray 5, a once-through blower 2 surrounded by a stabilizer 7 and a rear casing 8, and an outlet 6a in a part of an arc-shaped side wall.
It has a structure having. However, since the outlet 6a has an arc shape, the distance between the once-through blower 2 and the end of the outlet 6a is different as shown in FIGS.

When the once-through blower 2 is rotating and performing a blowing action, air is sucked downward from the front grille 4 which is a suction port, and the heat exchanger 3 and the stabilizer 7 are sequentially located downstream from the front grille 4.
The air flows to the once-through blower 2 surrounded by the rear casing 8 and the arc-shaped outlet 6a. Thus, since it is installed in the corner of the living room, there is no feeling of oppression and the integration with the interior is better. In addition, since the air is blown out from the quarter-arc-shaped outlet at a wide angle, there is no temperature unevenness in the indoor air conditioning, and the comfort is more excellent.

(Embodiment 2) A second embodiment of the present invention will be described with reference to FIGS. 2 and 3A. In addition, a triangular corner portion between the rear casing 8 and the outer box 10 will be described. An electrical box 9 having a substantially triangular prism shape was provided. As a result, it is possible to improve the storability of the components of the indoor unit, contribute to the downsizing of the outer dimensions, and to excel in integration with the interior.

(Embodiment 3) Further, it is attached to the ceiling of the living room and the corner of the two walls in close contact with each other, has a suction port on the lower surface, and has an outlet 6a on a part of the lower surface.
A fan-shaped trapezoid-shaped indoor-side air blower circuit, a front grille 4 serving as a suction port is provided below, and a heat exchanger 3, a stabilizer 7, and a rear mounted on a water receiving tray 5 in this order on a leeward side. A once-through blower 2 surrounded by a casing 8 has a rectangular outlet 6a provided with a wind direction changing device 6 having an arc-shaped cross section in a part of the lower surface.

When the once-through blower 2 is rotating and performing a blowing operation, air is sucked downward from the front grille 4 which is a suction port, and the heat exchanger 3 and the stabilizer 7 are sequentially located downstream therefrom.
The air flows to the once-through blower 2 surrounded by the rear casing 8 and the rectangular outlet 6a on the lower surface.

[0018] Thus, since it is installed in the corner of the living room and a part of the side surface is in an arc shape, there is no feeling of oppression, and it is excellent in integration with the interior. Further, since the wind direction changing device 6 can be slid from the rectangular outlet 6a at the corner and blown out toward the living room at a wide angle, there is no temperature unevenness in the indoor air conditioning, and the comfort is more excellent.

[0019]

As is clear from the above description, it is attached to the ceiling of the living room and the corner of the two walls in close contact.
This is a quarter-circular fan-shaped trapezoidal indoor-side ventilation circuit having a suction port below and a blow-out port at the arc. When the once-through blower rotates and blows air, it draws in air from the front grill, which is the suction port, downwards, and in turn, a once-through blower surrounded by a heat exchanger, stabilizer and rear casing, and an arc-shaped blower. Air flows to the outlet. Thus, since it is installed in the corner of the living room, there is no feeling of oppression and the integration with the interior is better. In addition, since the air is blown out from the quarter-arc-shaped outlet at a wide angle, there is no temperature unevenness in the indoor air conditioning, and the comfort is more excellent.

Further, since a substantially triangular electrical box is provided at a triangular corner portion between the rear casing and the outer box, it can contribute to downsizing of the indoor unit and is excellent in integration with the interior.
