DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner installed in a corner of a room for cooling or heating.

[0002]

2. Description of the Related Art A conventional air conditioner of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 9-166353.
The configuration is as shown in FIGS.

That is, in FIG. 1, reference numeral 1 denotes an indoor unit main body of an air conditioner, and the indoor unit main body 1 is in close contact with a corner portion between a ceiling (not shown) in a living room and walls 2a and 2b in two directions. It has a suction grille 3 that is a suction port for indoor air at the lower part of the indoor unit main body 1, and has a substantially arc-shaped trapezoidal trapezoid shape having a blow-out port 4 at a part of a front arc surface. I have. In the indoor unit body 1, a cross flow fan 5 and a reverse L
A heat exchanger 6 having a U-shaped heat exchanger 6 and an air filter 7.
Is provided with a stabilizer 9 having a water receiving tray 8 formed below. When the cross flow fan 5 rotates,
A blowing action in the direction of the arrow shown in FIG. 3 occurs, whereby the room air is sucked in from the lower suction grille 3, passes through the air filter, and is heat-exchanged by the heat exchanger 6.
It is blown out from the outlet 4. In addition, 10 is an indoor unit connection pipe, 11 is an outdoor unit connection pipe, 12 is an inside and outside connection pipe connection part, and 13 is a wind direction changing device.

[0004]

However, in the above configuration, the indoor unit connection pipe 10 and the outdoor unit connection pipe 11 are connected inside the indoor unit 1 when the indoor unit 1 is installed. When the suction grill 3 was opened for cleaning of the pipe 7, both the pipes and the internal / external connection pipe connection section 12 were exposed, and were unsightly. In addition, these two pipes and the inside and outside connection pipe connection portion 1
2 is located on the air path, the pipe is not attached so as to follow the upper shape of the indoor unit main body 1 after the pipe connection work at the time of installation, and if it is left largely protruding on the air path, the ventilation There was also a risk that the resistance was increased, the performance was deteriorated, the air flow was disturbed, and noise was generated.

The present invention has been made to solve the above-mentioned conventional problems, and provides an air conditioner that improves the appearance of a pipe connection portion at the time of connection of a pipe in a main body and ensures a stable air flow. .

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to cover a pipe connecting portion with a cover having a low ventilation resistance and a shape for generating a stable wind flow.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to solve the above-mentioned problems, the present invention covers a pipe connection portion with a cover having a low ventilation resistance and a shape that generates a stable wind flow. The internal / external connection pipe connection is not exposed and has a good appearance.The internal / external connection pipe connection fits inside the cover, does not protrude significantly on the air path, and the cover rectifies the intake air, thus reducing noise. Is reduced.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, reference numeral 1 denotes an indoor unit main body of an air conditioner, and the indoor unit main body 1 includes a ceiling (not shown) in a living room, a two-way wall 2 a,
2b, which is attached in close contact with the corner of the unit 2b, has a suction grill 3 at the lower part of the indoor unit main body 1, which is a suction port for indoor air, and has a blow-out port 4 at the arcuate surface portion of the front surface. It has the shape of a circular sector trapezoid. A stabilizer 9 having a cross flow fan 5 and an inverted L-shaped heat exchanger 6 and an air filter 7 on the windward side in the indoor unit main body 1, and a water receiving tray 8 formed below the heat exchanger 6. Is provided.

When the cross flow fan 5 rotates, an air blowing action in the direction of the arrow shown in FIG. 1 is generated, whereby the room air is sucked in from the lower suction grill 3, passes through the air filter, and is heated by the heat exchanger 6. After the replacement, the air is blown out from the air outlet 4. Reference numeral 10 denotes an indoor unit connection pipe, 11 denotes an outdoor unit connection pipe, 12 denotes an inside / outside connection pipe connection part connecting the indoor unit connection pipe 10 and the outdoor unit connection pipe 11, and 13 denotes a pipe cover. The pipe cover 13 is attached so as to cover almost the entirety of the two connection pipes 10 and 11 and the inside / outside connection pipe connection part 12 after the pipes are arranged along the upper shape of the indoor unit main body 1 after the pipe connection work. The pipe cover 13 prevents the two connection pipes 10 and 11 and the inside and outside connection pipe connection portion 12 from protruding largely on the air path, and prevents the performance from being deteriorated by increasing the ventilation resistance.

Further, the shape of the pipe cover 13 is made smooth so that the air flows smoothly from the suction grill 3 to the heat exchanger 6 without being disturbed, so that the air flow is adjusted and a stable air flow is obtained. Can be. Further, even if the suction grill 3 is opened to clean the air filter 7 after the indoor unit 1 is installed as shown in FIG.
The appearance is improved without being exposed.

[0011]

According to the present invention, as is apparent from the above description,
By providing a pipe cover that covers the inside / outside connection pipe and the inside / outside connection pipe connection, the appearance of the pipe connection at the time of service and maintenance is improved, a constant air path is secured, and the flow of wind is regulated. This makes it possible to obtain a stable air blowing performance with a wind circuit, thereby reducing noise.
