Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall mounted compact air conditioner, and more particularly to a heat exchanger and a blower inside, and a main cabinet from a back cabinet, a front cover and a suction cover. The present invention relates to a wall mounted compact air conditioner having a plurality of upper suction grids formed so as to straddle a front cover and a suction cover.

[0002]

2. Description of the Related Art In a conventional wall-mounted air conditioner, a main body cabinet has a horizontally long box shape, a heat exchanger and a blower are provided inside, and the main body cabinet is provided on a back cabinet and a front surface of the back cabinet. It is composed of a front cover provided and a suction cover provided on the front surface of the front cover, sucks indoor air through a suction portion provided on the front surface or the upper surface of the main body cabinet, and exchanges heat with a heat exchanger. After that, the structure is such that hot air or cold air is blown out from the air outlet provided on the lower surface of the main body cabinet. The suction part provided on the upper surface of these conventional examples is shown in FIG.
As shown in FIG. 2, the front cover is provided with a suction portion in which a plurality of horizontal rails are reinforced by vertical ribs, and a suction portion formed in the suction cover so as to be continuous with the suction portion.

In recent years, in order to make the main body cabinet look as compact as possible, there has been a form in which the upper and lower surfaces of the main body cabinet are narrowed forward.

The conventional example is, for example, registered design No. 811.
It is disclosed in Japanese Patent No. 938.

[0005]

In the above-mentioned conventional example, in consideration of the compatibility with the installation environment, the front suction portion visible to the user in the installation state is eliminated or minimized, and is provided on the upper surface. The opening ratio is secured by enlarging the suction part.

However, in recent years, wall-mounted air conditioners have a form in which the upper and lower surfaces of the main body cabinet are narrowed forward in order to make the main body look compact. Therefore, the suction portion arranged on the upper surface is relatively easy for the user to see.

On the other hand, the conventional suction portion arranged on the upper surface is
As shown in FIG. 10, the horizontal rail provided at the abutting portion of the front cover and the suction cover is configured such that the horizontal rail of the front cover and the horizontal rail of the suction cover are adjacent to each other. The horizontal rail in this part was thicker than other horizontal rails, and there was no sense of unity in the entire suction section. In this case, it is conceivable to make the horizontal rails thin at this portion to have the same pitch, but there is a problem in terms of strength of the horizontal rails.

On the other hand, if the other horizontal rails are thickened to have the same pitch, the suction portion as a whole must be made large in order to obtain a predetermined aperture ratio. Further, in the above-mentioned conventional example, since the horizontal bar is formed at the abutting portion of the suction cover, the opening of the suction cover is provided at the front by the width of the horizontal bar, which is easy for the user to see. Was there.

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to provide a suction portion of the main body cabinet which is strong in strength, yet has a design-integrated feeling, and is hard to be seen by the user. It is to provide a compact air conditioner provided on the upper surface.

[0010]

In the present invention, in order to achieve the above object, the main body cabinet is provided with a back cabinet, a front cover provided on the front surface of the back cabinet, and a front surface of the front cover. It is composed of a suction cover, and the inside of the main body cabinet is provided with a convex part of a heat exchanger in which two flat parts are intersected in a "V" shape, which is inclined toward the front, and is provided at the rear of the heat exchanger. A blower is provided, and a plurality of front suction grids for sucking air toward the lower flat surface portion of the heat exchanger are formed in the suction cover.
A plurality of upper suction grids for sucking air toward the upper flat portion of the heat exchanger are formed so as to straddle the front cover and the suction cover, and the upper surfaces of the front cover and the suction cover are inclined forward. In addition to forming an inclined surface, the suction cover is cut out at the end to form the opening of the suction grid, and a plurality of reinforcing ribs continuous in the front-rear direction are provided in the openings of the plurality of upper suction grids. ing.

[0011]

According to the present invention, by cutting out the end portion of the suction cover to form the opening portion of the suction grid, it is possible to substantially reduce the number of horizontal crosspieces. Only, the opening formed on the suction cover side can be formed on the front cover side.

[0012] The absence of the cross rails makes it possible to increase the suction area, reduce the suction resistance, reduce the fan noise, increase the suction air amount, and improve the heat exchange performance. Further, the horizontal rails are not overlapped with each other and are evenly spaced so that the air suction distribution is uniform, the heat exchange performance is improved, and the noise can be reduced.

Further, by providing a plurality of reinforcing ribs continuous in the front-rear direction in the openings of the plurality of upper suction grids, the sense of unity of the entire suction portion is enhanced, and further, the reinforcement ribs formed in the openings. It is possible to sufficiently receive the external pressure applied to the suction cover.

Since there is no cross rail at the end of the suction cover, the size of the reinforcing rib in the vertical direction can be made smaller than that of the cross rail, and the gap between the front cover and the suction cover can be made smaller. It reduces the flow of air without heat exchange into the fan.

And the upper suction opening 11b provided in the suction cover-4.
Composed of and. The upper surface suction opening 11a includes horizontal hole-shaped grid openings 21a to 21d left on both sides of the main body cabinet 1 and the grid openings 21a to 21d.
The horizontal rails 22a to 22d forming d and the grid opening 2
1a to 21d are divided into substantially equal parts in the left-right direction and cross rails 22a to 2
It is composed of a plurality of reinforcing ribs 23a to 23g that connect 2d. Here, the horizontal rail 22d is formed as an edge portion of the front cover-3, and the front cover-3 and the suction cover-4 are formed.
And the butt line 24 at the joint portion with.

On the other hand, the upper surface suction opening 11b has a grid opening 25a formed by cutting out an edge of the suction cover 4 on the side of the front cover-3, and the grid opening 25a.
Grid opening 25b formed further forward (downward in FIG. 6)
Composed of and. A plurality of reinforcing ribs 27a to 27g are formed on the horizontal rail 26 that separates the grid opening 25a and the grid opening 25b so as to maintain a predetermined interval. Here, the grid opening 25a is formed by the horizontal rail 26 and the horizontal rail 22d.

Further, the grid openings 25a and 25b have the same width as the grid openings 21a to 21d and have substantially the same pitch. In addition, the reinforcing ribs 23a-23
g and 27a to 27g are horizontal rails 22a to 22d and 2
6, which is one step lower than the horizontal crosspieces 6a and 6b.
2d and 26 are arranged so that one is left and right.

Further, a predetermined gap W1 is formed between the reinforcing ribs 27a to 27g formed in the grid opening 25a and the front cover-3. The gap W1 is set to a size such that the reinforcing ribs 27a to 27g do not make unreasonable contact with the front cover 3 when the suction cover 4 is opened. Reinforcing ribs 23d and 27d formed substantially in the center of the upper surface suction openings 11a and 11b are preferably configured to have a larger width than other reinforcing ribs to increase strength.

As described above, according to the present embodiment, the large curved surface 1 in which the upper and lower surfaces of the main body cabinet 1 are narrowed forward.
Since it is composed of 2 and 13, the main body cabinet 1 can be made compact when installed on the wall surface. Further, the upper surface suction opening 11 arranged on the curved surface 12 is a suction grid opening 25a formed by notching an end portion of the suction cover-4, and a horizontal crosspiece 26 having the grid opening 25a formed in the suction cover-4. Front cover-3
By forming it with the horizontal crosspiece 22d formed in the above, it is possible to reduce one horizontal crosspiece formed in the suction cover-4, so that the upper surface suction opening 11b is located rearward by the width of this horizontal crosspiece, and the installation state is set. Thus, it is possible to make the upper surface suction opening 11a hard to see, and to easily make the upper surface suction opening 11 at the same pitch.

The absence of the cross rail allows the suction area to be increased, the suction resistance to be reduced, the fan noise to be reduced, the amount of suction air to be increased, and the heat exchange performance to be improved. Further, the horizontal rails are not overlapped with each other and are evenly spaced so that the air suction distribution is uniform, the heat exchange performance is improved, and the noise can be reduced.

Further, since the reinforcing ribs 27a to 27g are formed in the grid opening portion 25a located at the butt line 24, even if the suction cover 4 receives a pressure from the front during packing or installation, the reinforcing ribs 27a to 27g. With 27 g, the rigidity can be increased by receiving the pressure. In addition, since the reinforcing ribs 27a to 27g are formed continuously with the reinforcing ribs 23a to 23g, even if the upper surface suction opening 11 can be recognized in the installed state, the sense of unity between the upper surface suction openings 11a and 11b is enhanced. Therefore, the design can be improved.

FIG. 1 is a perspective view of a part of the main portion of the joint between the front cover 3 and the suction cover-4. Since there is no horizontal crosspiece at the end of the suction cover-4, the reinforcing ribs are better than the horizontal crosspieces. Since the size in the vertical direction is made small and the gap W1 at the joint portion between the front cover 3 and the suction cover 4 required when opening the suction cover 4 upward as shown in FIG. Can be reduced to the fan.

According to the present invention, as shown in FIG. 8, the upper surface suction opening 11b formed in the suction cover-4.
Opening 2 formed by notching the end of the cover 4
8 may be provided with the reinforcing ribs 30, or, as shown in FIG. 9, both ends of the suction cover 4 and the front cover 3 are cut out to form the openings 29, and the reinforcing ribs 31 are provided. Even if formed, the same effect can be obtained.

[0030]

According to the present invention, by making the upper surface of the main body cabinet an inclined surface which is inclined forward, the main body cabinet can be made compact and the side surface of the upper surface suction opening disposed on the inclined surface. By reducing the crosspieces, the upper surface suction opening can be made less visible by the size of the crosspieces. It can also be located rearward.

The absence of the cross rails makes it possible to increase the suction area, reduce suction resistance, reduce fan noise, increase the amount of suction air, and improve heat exchange performance. Further, the horizontal rails are not overlapped with each other and are evenly spaced so that the air suction distribution is uniform, the heat exchange performance is improved, and the noise can be reduced.

Further, by dividing the entire suction portion including the opening portion into the right and left portions and continuing them in the front-rear direction, the reinforcing ribs enhance the sense of unity of the entire suction portion. As a result, the rigidity can be increased by receiving the external pressure applied to the suction cover.

Further, since there is no cross rail at the end of the suction cover, the reinforcing rib can be smaller in the vertical dimension than the cross rail, so that the gap between the front cover and the suction cover can be made smaller. It reduces the flow of air without heat exchange into the fan.
