Description

  The present invention comprises a front panel including a front suction port, an upper surface suction port, and a lower blowout port and a casing, and includes a heat exchanger and a blower fan inside, and is supported by the front panel so that it can be opened and closed. It is related with the air conditioner which has an open panel which opens and closes.

  In recent years, wall-mounted air conditioners that are attached to a wall surface higher than the line of sight are favored for designs that harmonize with the interior of the room where they are installed. For this reason, colors with high brightness such as white and beige, which are often used for indoor wallpaper, are adopted as the main body color. In addition, in the form, it is compact so that it can be attached to any wall, and furthermore, the presence of irregularities due to the suction port and air outlet is conspicuous so that the interior will not feel strange, Many air intakes are closed with a flat open panel and the air outlet is closed with a wind direction plate.

  This air conditioner is composed of a front panel with a front inlet, an upper inlet and a lower outlet, and a casing. The air conditioner has a heat exchanger and a blower fan inside, and is supported by the front panel so that it can be opened and closed. And an open panel for opening and closing the suction port. The lower outlet is provided with a wind direction plate that opens and closes it. During operation, the open panel moves forward and opens the front suction port, sucking air from the front suction port, sucking air from the top suction port, and opening the wind direction plate to exchange heat from the blower outlet. Blow out the air. When the operation is stopped, the open panel and the wind direction plate are closed, so that the appearance is flat with no irregularities, and a design that matches the interior can be obtained.

  Some air conditioners of this type have a design in which the upper edge of the front inlet and the open panel joint appear on the front side because the load on the movable motor can be reduced by reducing the size of the open panel. For example, in the past, a seam is provided on the same curved surface connecting the open panel and the upper edge of the front suction port, and the open panel and the upper edge of the front suction port are integrated. When the same curved surface of the joint at the upper edge of the mouth does not accurately match, the shift is conspicuous, so a gap is provided at the joint (see, for example, Patent Document 1). However, in that case, dust easily collects at the joint.

  Therefore, as shown in FIG. 7A, when the open panel 20 is stopped, that is, when the open panel 20 is closed, the angle A ′ at the lower end of the inclined surface 12a of the upper edge 12 of the front suction port 11 is When the design is made so that the upper end corner B ′ of the vertical surface 20a of the open panel 20 coincides, the seam E ′ has a mountain shape, and no dust or dirt accumulates on the seam, and the design is clean. Become.

  However, the open panel 20 is made of a resin having a thickness of about 2 mm and a width of 70 cm or more, and no back-surface reinforcing ribs are provided in order to ensure designability. In some cases, a maximum of 3 mm protrudes and swells to cause bending. In this case, as shown in FIG. 7B, the upper corner B ′ of the vertical surface 20 a of the open panel 20 projects forward from the corner A ′ of the lower end of the inclined surface 12 a of the upper edge 12 of the front suction port 11. As a result, the seam E ′ is displaced. Since this projecting portion occurs near the center of the open panel 20 in the lateral direction, the design is significantly impaired.

  An object of the present invention is to provide an air conditioner that does not leave a gap at the joint between the open panel and the upper edge of the front suction port, and that does not make the misalignment due to the deflection near the center of the open panel inconspicuous. That is.

In order to achieve the above object, an air conditioner according to a first aspect of the present invention includes a front panel including a front inlet, an upper inlet, and a lower outlet and a casing, and a heat exchanger inside. In an air conditioner having a blower fan and supported by the front panel so as to be openable and closable and opening and closing the front suction port, the front suction port side protrudes in the front direction at the upper edge of the front suction port. 1 is provided, and the open panel has a vertical surface on the front side, and the upper surface of the open panel is parallel to the first inclined surface of the upper edge of the front suction port and from the first inclined surface. A second inclined surface that is located on the back side by a first distance, and a third inclination that extends continuously downward from the bottom of the first inclined surface at the upper edge of the front suction port. A surface is provided.
According to a second aspect of the present invention, in the air conditioner according to the first aspect, the vertical surface of the open panel is formed between the first inclined surface and the third inclined surface of the upper edge of the front suction port. It is characterized by being positioned in the back direction by a second distance from the corner.
According to a third aspect of the present invention, in the air conditioner according to the first or second aspect of the present invention, a fourth inclined surface that faces obliquely downward is continuously formed on the back side of the second inclined surface of the open panel. And forming a fifth inclined surface that is continuous obliquely downward from the third inclined surface at the upper edge of the front suction port and that connects the fourth and fifth inclined surfaces to each other. It is characterized by parallel surfaces.

  According to the present invention, the open panel is parallel to the first inclined surface at the upper edge of the front suction port and is at the first distance from the first inclined surface so as to be continuous with the upper portion of the vertical surface. Since the second inclined surface located on the side is provided, even if the open panel bends and the front bends in the vicinity of the center, the first inclined surface is viewed from the bottom of the air conditioner. Since the inclined surface and the second inclined surface appear continuously, there is no sense of discomfort in design.

  In addition, a third inclined surface that extends continuously downward from the lower side of the first inclined surface is provided on the upper edge of the front suction port, and the vertical surface of the open panel is connected to the upper edge of the upper edge of the front suction port. When it is normal that the open panel is not bent by being positioned in the back direction by a second distance from the angle of the first inclined surface and the third inclined surface, when looking up from the bottom of the air conditioner, Since it appears that the corners of the first and third inclined surfaces of the upper edge of the front suction port and the vertical surface of the open panel are aligned vertically, this point is also in terms of design. There is no sense of incongruity.

It is a perspective view at the time of operation stop of an air harmony machine of an example of the present invention. It is a perspective view at the time of the driving | operation of the air conditioner of the Example. It is a schematic sectional drawing of the air conditioner of the Example. It is a right view of the air conditioner of the same Example. FIG. 5 is an enlarged view of a portion X in FIG. 4. It is a side view of the upper edge of the open panel and front suction port of the air conditioner of the embodiment. It is a side view of the upper edge of the open panel and front suction port of the conventional air conditioner.

  1 and 2 show the appearance of the air conditioner of the first embodiment of the present invention, and FIG. 3 shows the internal configuration. The air conditioner according to the present embodiment includes a front panel 10 and a casing 18 that include a front air inlet 11, an upper edge 12 of the front air inlet 11, an upper air inlet 13, and a lower air outlet 15 that is opened and closed by a wind direction plate 14. The main body is configured, and the heat exchanger 16 and the blower fan 17 are included therein, and the open panel 20 is supported by the front panel 10 so as to be opened and closed and opens and closes the front suction port 11.

  During operation, air is sucked from the upper surface suction port 13, and the open panel 20 rotates forward to open the front surface suction port 11, thereby sucking air from the front surface suction port 11. Further, the air direction plate 14 is opened, and the air sucked from the front air outlet 11 and the upper surface air inlet 13 and heat-exchanged with the refrigerant by the heat exchanger 16 is blown out from the air outlet 15 by the blower fan 17 (FIG. 2). The open panel 20 may have a structure that moves in parallel forward and opens the front suction port 11. When the operation is stopped, the open panel 20 and the wind direction plate 14 are closed (FIG. 1).

  4 is a right side view of the air conditioner of the present embodiment, and FIG. 5 is an enlarged view of a portion X in FIG. In the upper edge 12 of the front suction port, 12a is an inclined surface (first inclined surface) whose lower side protrudes forward, and 12b is an inclined surface (fifth inclined surface) that is a mating surface of the upper edge 12 and the open panel 20. ), 12c is an inclined surface (third inclined surface) that connects the inclined surfaces 12a and 12b so that the inclined surface 12b is retracted in the depth direction. Further, in the open panel 20, 20a is a vertical surface, 20b is an inclined surface (fourth inclined surface) which is a mating surface facing the inclined surface 12b of the upper edge 12 of the front suction port 11 in parallel, and 20c is a vertical surface 20a. And an inclined surface (second inclined surface) that connects the inclined surface 20b so that the inclined surface 20b side recedes in the back direction.

The shapes and positional relationships of the surfaces 12a to 12c and 20a to 20c are determined as follows.
(1). The inclined surfaces 12b and 20b in which the upper edge 12 of the open panel 20 and the front suction port are close to each other take into account that the upper end of the open panel 20 rotates forward with the lower end as a fulcrum, or is translated and opened forward. The inclined surfaces are parallel to each other and are inclined downward in the back side.
(2). The inclined surface 12a of the upper edge 12 of the front suction port 11 is determined so that the lower side protrudes forward.
(3). Assuming that the forward deflection at the central portion of the open panel 20 is 2 to 3 mm, the distance t1 (2 to 3 mm) from the extended line of the inclined surface 12a of the upper edge 12 of the front suction port 11 on the far side, An inclined surface 20c of the open panel 20 is determined in parallel with the inclined surface 12a.
(4). The point immediately above the angle C between the inclined surface 20c and the inclined surface 20b is defined as an angle D, and the downward inclined surface 12c of the upper edge 12 of the front suction port 11 is determined between the angle D and the inclined surface 12a. The length connecting the corner A and the corner D of the inclined surface 12 c is longer than the length connecting the corner B and the corner C of the inclined surface 20 c of the open panel 20.
(5). The vertical surface 20a of the open panel 20 is determined to be at the back side by a distance t2 (0 to 2 mm) from the vertical line of the angle A between the inclined surface 12a and the inclined surface 12c of the upper edge 12 of the front suction port 11.

  As described above, when the operation of the air conditioner is stopped, if the open panel 20 does not bend and is normal, as shown in FIG. 6A, the air conditioner attached to the wall surface higher than the line of sight. When looking up from the bottom, it appears that the perspective is attached, so that the corner A of the upper edge 12 of the front suction port 11 and the vertical surface 20a of the open panel 20 appear to be aligned vertically. In this case, when the corner C and the corner D appear to overlap each other, the seam E is formed, and it seems that the inclined surfaces 12c and 20c are provided on the upper and lower surfaces of the seam E, giving a clean impression and impairing the design. Absent.

  On the other hand, when the center of the open panel 20 is bent forward by t1, the inclined surface 12a of the upper edge 12 of the front suction port 11 and the inclined surface 20c of the open panel 20 are the same as shown in FIG. It will appear to be lined up on the line. For this reason, when looking up from the bottom, the inclined surface 12a of the upper edge 12 of the front suction port 11 and the inclined surface 20c of the open panel 20 are continuously viewed in a straight line, giving a sense of incongruity that the portions are shifted. Without damaging the design.
