Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an indoor unit of an air conditioner according to an embodiment of the present invention with a panel opened, and FIG. 2 is a cross-sectional view in side view.

  As shown in FIGS. 1 and 2, the air conditioner of the present embodiment includes a housing 2 having a suction port 1 formed on the top surface and a panel 3 that is rotatably attached to the housing 2. . The panel 3 has a flat front surface. Moreover, the housing | casing 2 has the blower outlet 4, The wind direction change board 5 is provided in the blower outlet 4. FIG. Note that the panel 3 and the housing 2 form an exterior body.

  A pair of left and right pivoting arms 7 having a shaft 6 as shown in FIG. 3 are provided on the back side of the panel 3, and the shaft 6 of the arm 7 is arranged on the housing 2 side as shown in FIGS. The bearing structure 8 is fitted into and supported by the bearing portion 9.

  The bearing structure 8 includes a base 11 fixed to the housing 2 and a protruding piece extending from the base 11 to the front in the horizontal direction. Here, the tip extends from the base 11 to the front in the horizontal direction, and the tip is folded in a vertical plane. A U-shaped piece 12 and a bearing portion that extends from the base 11 so as to face the upper surface 12 a of the U-shaped piece 12 and can be mounted with the shaft 6 of the arm 7 together with the upper surface 12 a of the U-shaped piece 12. The upper surface 12a and the lower surface 12b of the U-shaped piece 12 are formed in an arc surface having the center of the bearing portion 9 as the arc center.

  On the other hand, when the shaft 6 is mounted on the bearing portion 9, the arm 7 engages with the lower surface (arc surface) 12 b of the U-shaped piece 12 (slids on the arc surface) and moves together with the shaft 6. An arc-shaped holding rib 14 is provided to hold 12 from above and below.

  Then, the U-shaped piece so that the engagement between the circular arc surface on the lower surface 12b side of the U-shaped piece and the holding rib 14 is released at a specific angle position (position where the panel 3 is horizontal) as shown in FIG. 12, the length of the circular arc surface on the lower surface 12b side is set, and the shaft 6 can be attached to and detached from the bearing portion 9 only at the specific angle position.

  Further, the base 11 has a side surface of the arm 7 at a predetermined angular position (FIG. 7) on the way to an angular position where the engagement between the arc surface on the lower surface 12b side of the U-shaped piece 12 and the holding rib 14 is released. A pair of elastic pieces 16 that are engaged with the projections 15 and receive the load of the panel 3 and hold the arm 7 are provided upright.

  Further, the housing 2 is provided with a recess for accommodating the bearing structure 8 as shown in FIG. 1, and a hooking portion 17 for locking the bearing structure 8 is provided on the upper side. A receiving portion 18 for receiving and fixing and holding the bearing structure 8 as shown in FIG. 6 is provided on the lower side.

  The bearing 9 of the bearing structure 8 is provided with a guide 9a whose tip is opened larger than the diameter of the shaft 6 as shown in FIGS. 4 and 5 so that the shaft 6 of the arm 7 can be easily fitted. Further, the opening 9b on the proximal end side of the guide 9a is narrower than the diameter of the shaft 6 so that the shaft 6 does not come off. The U-shaped piece 12 constituting the bearing portion 9 has a plate-like elastic shape so that the shaft 6 can be easily inserted by being deformed when the shaft 6 is fitted, and there is no particularly strong reinforcement.

  During operation such as air conditioning, the U-shaped piece 12 is sandwiched between the shaft 6 of the arm 7 and the sandwiching rib 14 with the panel 3 closed as shown in FIG. That is, the shaft 6 is supported by the upper surface 12 a of the U-shaped piece 12, and abuts against the sandwiching rib 14 by the lower surface 12 b of the U-shaped piece 12.

  When the panel 3 is in a horizontal state, as shown in FIG. 8, the position of the sandwiching rib 14 is shifted from the engagement position with the lower surface 12 b of the U-shaped piece 12, and the shaft 6 of the arm 7 of the panel 3 is moved. By pulling out from the bearing portion 9 in the horizontal direction, the U-shaped piece 12 is mainly deformed and the panel 3 can be removed.

Next, the operation of the air conditioner configured as described above will be described.
When the operation is started, the room air is sucked from the suction port 1 of the housing 2, and the temperature is adjusted by the heat exchanger 30 shown in FIG. Blown out. At this time, since dust in the room air is removed and attached by the filter 20, it is desirable to clean the filter 20 for example once every two weeks. In this case, when the panel 3 is rotated by moving the lower end of the panel 3 diagonally forward and rotated to a predetermined diagonal direction, the convex portion 15 of the arm 7 becomes a bearing structure as shown in FIG. Riding on the tip of the elastic piece 16 on the base 11 of 8, the panel 3 is held in an open state. At this time, the shaft 6 of the arm 7 is supported on the upper surface 12 a of the U-shaped piece 12 of the bearing portion 9, and the lower surface 12 b of the U-shaped piece 12 is in contact with the holding rib 14. Even if the panel 3 is pulled, the opening 9b between the bearing forming piece 13 and the upper surface 12a of the U-shaped piece 12 is not widened, and the panel 3 is not detached.

  When the panel 3 is supported in an obliquely downward direction as shown in FIGS. 1 and 7, the filter 20 is exposed, so that the filter 20 can be removed to remove dust.

  When the air conditioner is operated, the air on the primary side passes through the suction port 1 and the back side of the panel 3 and then passes through the filter 20, so that the back side of the panel 3 is easily contaminated by static electricity or the like. For this reason, it is desirable to remove the dirt by removing the panel 3 from the housing 2 and washing it with water.

  In order to remove the panel 3, first, the panel 3 is rotated until the panel 3 is oriented in a substantially horizontal direction. Then, as shown in FIG. 8, the holding rib 14 that is in contact with the lower surface 12 b of the U-shaped piece 12 of the bearing structure 8 is shifted upward, and the restriction of the U-shaped piece 12 by the holding rib 14 is released. It is burned. Next, when the panel 3 is pulled toward the front, the U-shaped piece 12 is lowered, and the shaft 6 of the arm 7 is detached from the bearing portion 9, so that the panel 3 can be removed. Thereby, the panel 3 can be washed with a circle.

  After removing the dirt on the panel 3, the panel 3 is attached. In this case, the panel 3 is attached in the reverse order of removal. First, the panel 3 is oriented so as to face the horizontal direction, and the arm 7 is aligned so as to face the bearing structure 8 of the housing 2. When the panel 3 is pushed from the front side to the back side in this state, the U-shaped piece 12 is deformed from the base by the shaft 6 of the arm 7 (the distance between the upper and lower surfaces 12a and 12b on the tip side does not change), and the arm 7 shaft 6 is attached to bearing 9. Since the opening 9b of the bearing portion 9 is narrower than the diameter of the shaft 6 of the arm 7, the shaft 6 does not come off. In this state, if the lower end of the panel 3 is rotated so as to draw an arc with the shaft 6 as a fulcrum, the upper surface 12a of the U-shaped piece 12 of the bearing portion 9 remains supported by the shaft 6 while the U-shaped piece 12 The lower surface 12b is in contact with and fixed to the sandwiching rib 14. For this reason, even if the operator pulls the panel 3 at an angle other than the angle at which the panel 3 faces in the horizontal direction, the panel 3 will not come off. Then, when the panel 3 is rotated until it is directed downward, the attachment of the panel 3 is completed.

  As described above, in the air conditioner of the present embodiment, the shaft 6 of the arm 7 is supported on the upper surface 12a of the U-shaped piece 12 of the bearing structure 8 except for the angle at which the panel 3 faces the horizontal direction. The lower surface 12b of the U-shaped piece 12 is in contact with the holding rib 14, and the distance between the upper and lower surfaces 12a, 12b on the distal end side of the U-shaped piece 12 does not change and is firmly fixed. There is a risk that the operator may be easily injured due to deformation of the parts of the panel mounting part, etc., even if the operator is gripped by the panel 3 and the load is applied to the operator other than when the user is leveled and removed. Disappear.

  In the above-described embodiment, the U-shaped piece 12 extending from the base 11 in the horizontal direction and having the tip folded back in the vertical plane is described as an example of the protruding piece. However, the present invention is not limited to this. For example, as a protruding piece extending straight forward from the base in the horizontal direction, the bearing portion may be formed on the upper surface, and the upper and lower surfaces thereof may be formed into an arc surface having the center of the bearing portion as the arc center. Even in this case, an effect equivalent to that of the above-described embodiment can be obtained.

  In the above-described embodiment, the case where the arm is installed on the panel side and the bearing structure is arranged on the housing side has been described as an example. However, these positional relationships may be reversed. In that case, the installation position is on the upper surface side of the housing, the protruding piece (U-shaped piece) provided on the panel side protrudes upward from the upper end of the panel, and the arc surface with the center of the bearing portion as the arc center is the protruding piece ( What is necessary is just to form in the front surface and back surface of a character-shaped piece). Even in this case, an effect equivalent to that of the above-described embodiment can be obtained.
