Description

[Detailed explanation of the idea] The present invention relates to a novel structure of a vertically elongated air conditioner.

Air conditioners that are installed indoors and outdoors at windows and sweep areas must have a structure that allows for a high degree of freedom in entering and exiting both indoors and outdoors, and does not interfere with the freedom to open and close doors. is desirable, and therefore a vertically long so-called slim shape is suitable.

When using a slim structure like this, in order to ensure a sufficient air outlet area, especially for the indoor air outlet, the outlet inevitably becomes vertically long, but conventional air conditioners of this type have a casing. An elongated air outlet was provided along the tilted edge of the right or left edge of the front part.

Therefore, as shown in the installation example in Figure 9, when installed in a corner of a room, if a device with the right side air outlet is placed in the right corner, the air will blow out along the right wall. Become,
The problem is that the temperature distribution in the room is not averaged, and furthermore, since furniture and furniture such as chests of drawers are usually placed along the walls, the smooth circulation of the blown air is obstructed, and the airflow in the room is affected. The distribution deteriorated, which led to further unevenness of the temperature distribution, which was undesirable.

In addition, as demand-side house designs vary widely, in order to prepare air conditioners that can accommodate any layout, it is necessary to have two types of air conditioners: right-hand and left-hand. Therefore, there was also an economic disadvantage of increasing the manufacturing cost of the device.

The present invention has focused on this fact and has developed an air conditioner with a new structure that can be adapted to both left-handed and right-handed tilting with just one type of air conditioner, thereby solving the above-mentioned conventional defects. This is what we have fundamentally solved and obtained 7.
The specific contents of the present invention having such characteristics will be described in detail below with reference to the accompanying drawings.

As shown in Figs. 1 to 4, 1 is an air conditioner, such as a small household cooler, and the casing 1 has a vertically long slim shape whose length is considerably large compared to the interior and depth of the machine. I am doing it.

The interior of the casing 1 is divided into two chambers, a front chamber 2 and a rear chamber 3, and the rear chamber 3 is divided into two chambers, a front chamber 2 and a rear chamber 3.
A centrifugal fan 4-1 and an indoor coil 5-1 are housed in the front chamber 2, which is smaller than the previous chamber.

Furthermore, a blowout lower 17-1 and a suction port 8-1 are opened in the front of the front chamber 2, and a centrifugal fan is connected to the indoor coil 5-1 disposed facing the inside of the suction port 8-1. The indoor unit 4-1 is located on the leeward side, has front suction and rear outlet, and is an attraction type indoor unit.

On the other hand, the rear chamber 3 includes a centrifugal fan 4-2 and an outdoor coil 5-2.
2, compressor 6, and other incidental equipment,
On the rear surface of the rear chamber 3 are a blowout lower 2゜7-2 and a suction port 8-.
2 is opened, and the centrifugal fan 4-2 is located on the leeward side of the outdoor coil 5-2, which is disposed facing the inside of the suction port 8-2. Formed into a unit.

However, in the indoor unit, the centrifugal fan 4-1
, the blow-off lower 1.7-1, and the suction port 8-1 have a unique configuration, and this is the main component that characterizes the present invention.

First, the centrifugal fan 4-1 has a structure as shown in FIG.
・It is formed into a housing and is a twin-flow fan that can blow air from two sides in the same direction (forward direction).

The twin-vortex type housing 9 has two guide wall portions 12 and 12 forming an involute curved surface extending upward and downward symmetrically with respect to the axis of the rotor 10, and in front of the rotor 10. A vertically elongated blow-off portion 13.13 is connected to the open blow-off chambers 11, 11 at the center of the upper and lower parts of the suction portion 14 in the left-right direction.

Therefore, with such a structure, the rotor 10, which is energized by the double-shaft motor 15 shared with the centrifugal fan 4-2, divides the flow in the vertical direction of the rotor 10 and pumps the intake air, Twin-vortex type: After passing through the using 9 and changing direction by 90° at both the upper and lower blowing chambers 11, 11,
Air is sent forward from the elongated blow-off portion 13.13.

The blow-out chamber 11.11 may be a twin-vortex type . . . a simple rectangular box with a small size and a short depth that corresponds to the opening at the tip of the housing 9.

Next, regarding the blowout lower 7-1, it is located at the center of the front of the front chamber 2 in the direction of the machine, and has a vertically elongated shape above and below it, except for the part facing the suction part 14 of the centrifugal fan 4-1. Open each eye.

Both blowing lowers 1.7-1 are connected to the blowing chamber 11.
It is located just in front of the air outlet part 13.

On the other hand, the suction port 8-1 is provided in a portion facing the indoor coil 5-1 on the front surface of the front chamber 2, and is provided in a portion facing the indoor coil 5-1. It spreads around 7-1 and opens.

This suction port 8-1 communicates with the interior space of the front chamber 2 existing in front of the twin-vortex housing 9 via the indoor coil 5-1 [7], and communicates with the suction portion 14 of the centrifugal fan 4-1. .

In an indoor unit with such a structure, the indoor coil 5-1
It is necessary to have a shape that matches the opening surface shape of the suction port 8-1 surrounding both blow-out lowers 1.7-1, so two cross fin coils are installed side by side on the left and right, and wind fin coils are installed side by side on the left and right. A heat exchanger or the like having an air circulation surface corresponding to the shape of the opening surface by the coil can be used.

However, in the case shown in FIGS. 1 to 4, the unique form that characterizes the present invention is applied only to the indoor unit, but the present invention applies not only to the indoor unit but also to the indoor unit. As illustrated in FIGS. 5 to 7, it is possible to use similar structures in combination, and such forms are naturally included within the scope of the present invention.

The air conditioner that has a twin configuration is a blowout lower l.

7-1 is opened vertically in the center of the front of the slim casing 1, so that the blowing air flows along the side wall in both right-hand and left-hand usage, as shown in Fig. 8. Therefore, the air flow is not obstructed by furniture that is in close contact with the wall, and air conditioning operation can be performed with an averaged indoor air flow and temperature distribution.

The present invention is like a twin, at least for the air outlet lower 1 in the indoor unit. 71 has a vertical opening in the center of the vertically elongated casing 1, so when installed in a corner of a room, the blown air flows away from the wall surface, thus maintaining uniform airflow and temperature distribution. In addition to obtaining the left
It has versatility and can be applied to either right-handed or right-handed users at any time.

Furthermore, the centrifugal fan 4-1 can be made thin with a small depth, which has a great effect on making the machine body compact. If you want to use a central blowout method with this type of air conditioner, you will need to install a separate duct inside the casing.
As a result, the air resistance increases and the reduced air volume is compensated for by an increase in the fan rotation speed, resulting in a disadvantage of increased operating noise.In contrast, the present invention has a small air resistance and a weak blowing part. It has the advantage of being able to operate under high airflow conditions and in quiet conditions.

As described above, the present invention is a vertically elongated air conditioner that exhibits various excellent practical features.
