Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a configuration of an indoor air blower circuit of a separate air conditioner of a heat pump that performs air conditioning.
[0002]
[Prior art]
As shown in FIG. 7, the conventional indoor unit of a separate type air conditioner has been attached to the wall of the living room in a protruding form. The structure consisted of the front grill 4, the heat exchanger 3, the cross-flow fan 2 surrounded by the casing 21 and the stabilizer 20, and the up-and-down wind direction changing device 6 in order from the windward side. By rotating the once-through blower 2 with a motor, a blowing action is generated, and air flows in the order shown above as indicated by the arrows, and air conditioning and dehumidification are performed.
[0003]
[Problems to be solved by the invention]
However, since the indoor unit of the separate type air conditioner having the above-described structure is installed in a shape that protrudes from the wall of the living room, there is a limit to fusion with the interior by giving a pressure to the living room. Furthermore, since it is installed on one wall, even if the wind direction changing device is fully used, the air conditioning temperature distribution in the room is uneven and there is a problem in terms of comfort.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a blower circuit of a separate type air conditioner according to the present invention has a quarter-arc fan-shaped trapezoidal shape having a suction port below and a blow-off port in the arc part. In the circuit, a wind direction changing device having a circular arc shape and a substantially elliptical cross section is provided at the blowing port to blow the blowing flow vertically and horizontally .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
In the above-described configuration, the present invention provides a wind direction changing device having an arc shape and a substantially elliptical cross section, which blows the blowing flow vertically and horizontally at the arc-shaped blowing port, and by simply moving the wind direction changing device up and down. The blowout flow can be controlled in the downward, vertical and horizontal directions, and the air-conditioning temperature distribution in the room is not uneven, improving comfort .

【Example】
(Example 1)
A first embodiment of the present invention will be described below with reference to FIGS.
[0013]
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.
[0014]
FIG. 2 is a plan view of FIG. 1 viewed from the A direction.
FIG. 3 is a cross-sectional view of the BB.
[0015]
Indoor air conditioning in the form of a quarter-arc fan-shaped trapezoid that 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 blowout port 6a in the arc portion. Machine 1. When the centrifugal blower 2 is rotating and performing a blowing action, air is sucked downward from the front grille 4 as a suction port, and the centrifugal blower and the centrifugal impeller surrounded by the air guider 8 and the scroll casing 5 in that order in the downstream. The air flows in the radial direction 2 to the arc-shaped heat exchanger 3 and the arc-shaped outlet 6a, and performs a blowing action. Thus, since it is installed in the corner of a living room, there is no feeling of pressure and the fusion with an interior is more favorable. Since the air is blown out at a wide angle from the 1/4 arc-shaped air outlet 6a, there is no temperature unevenness in the indoor air conditioning and the comfort is better.
[0016]
(Example 2)
A second embodiment of the present invention will be described with reference to FIG.
[0017]
By forming the scroll casing 5 of the centrifugal impeller 2 into a basic shape with a spiral having the cross section 10, when the centrifugal impeller 2 rotates in the direction of the arrow and performs a blowing action, the blowing efficiency is higher and the noise is lower. An indoor fan circuit can be provided. The centrifugal impeller 2 may be configured with a backward fan or a sirocco fan.
[0018]
(Example 3)
The third embodiment will be described with reference to FIGS. 5- (a), (b), and (c).
[0019]
A wind direction changing device 6 having a circular arc shape and a substantially elliptical cross section is provided at the circular arc outlet 6a. When the wind direction changing device is moved up and down, the blowing flow can be blown downward by setting the wind direction changing device 6 to the upper position as shown in FIG. Further, as shown in FIG. 5- (b), when the wind direction changing device 6 is set at an intermediate position of the blowout port 6a, the upper and lower parts can be blown apart. Moreover, horizontal direction blowing can be performed by setting the wind direction changing device 6 to the lower position. In this way, the blowout flow can be controlled, the air-conditioning temperature distribution in the room is not uneven, and the comfort surface is improved.
[0020]
(Example 4)
A fourth embodiment will be described with reference to FIG.
[0021]
An internal connection pipe 9 from the indoor heat exchanger 3 is provided between the air guider 8 and the front grill 4 and is arranged at one corner of the indoor unit. Thus, the internal connection pipe 9 is efficiently accommodated without affecting the air flowing through the blower circuit, so that the indoor unit can be made compact, and as a result, it is further excellent in fusion with the interior of the living room.
[0022]
【The invention's effect】
As is apparent from the above description, by providing a wind direction changing device having an arc shape and a substantially elliptical cross section at the arc shaped outlet, the blowing direction is blown up and down horizontally. in the balloon flow, downward, vertical winnowing, can be controlled in the horizontal direction, there is no unevenness in the air-conditioning temperature distribution of the room, you better surface comfort.
