Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a grill mounting portion of an air conditioner.

[0002]

[Prior art]

 An air conditioner that takes in indoor air from the front, exchanges heat, and blows out downward has a filter installed on the front of the main unit and the front is covered with a grill. Since the filter needs to be cleaned at any time, the grill that can be taken out from the front is configured so that the grill can be opened and closed. FIG. 3 is a plan view of a main part of a conventional example, and FIG. 4 is a view taken along the line BB of FIG. As shown in the figure, the main body 1 has a filter (not shown) on the front surface, and the front side thereof is covered with a grill 2. On the upper end of the grill 2, a pair of arms 3 is provided rearward, and a cylindrical rotation shaft 4 is erected on the arm 3. On the other hand, a support plate 5 for supporting the rotating shaft 4 is provided on the upper front surface of the main body 1, and a notch 6 that is opened upward is provided on the supporting plate 5 so that the front wall is substantially vertical and the bottom portion is the rotating shaft 4. It has a curved surface, and the rear part is slightly tilted backward. In order to prevent the support plate 5 from falling off when opening and closing, a fan-shaped guide portion 7 is continuously provided in front of a lower portion of the notch 6 about the shaft center and an angle with respect to this is about 90 degrees. Is provided on the outside of the guide portion 7 and is provided with a fan-shaped engaging portion 8 centered on the shaft center and having an angle with respect to this of about 90 degrees. Therefore, when the grill 2 is removed from the main body 1 for cleaning or internal inspection and is then again fixed to the main body 1, the rotary shaft 4 is cut out from above so that the rotary shaft 4 is substantially horizontal as shown by the chain double-dashed line. The center of the fan-shaped part that forms the guide part 7 and the locking part 8 is aligned with the axis, so that when the grill 2 is rotated as it is, the closed position shown by the dotted line is obtained. It does not fall off in the range where the filter is normally opened and closed. However, if the grill 2 is accidentally locked at an angle smaller than the position indicated by the chain double-dashed line, the inner tip of the locking portion 8 abuts on the outer periphery of the guide portion 7, and the rotary shaft 4 becomes the bottom surface of the notch 6. There was a risk that the grill 2 would rotate and the rotary shaft 4 would be broken even if it did not come into contact with the rotary shaft, even though it did not.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the problems of the above-described conventional example, and an object of the present invention is to provide a grill mounting structure that can be easily and reliably locked without breaking.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention comprises a main body and a grill that covers the front of the main body. The upper part of the grill has a pair of arms protruding rearwardly and a rotary shaft in the longitudinal direction of the grill. A pair of support plates are provided with a shaft hole through which the rotary shaft is inserted, and a notch is continuously provided above the shaft hole, and the rotary shaft is inserted from above the support plate and engaged with the shaft hole. In the harmony machine, the support plate is surrounded by a shaft hole, and a fan-shaped guide body having an inclined surface is provided at a position lower than the shaft center, and the arm is provided with the rotation shaft as a center. Enclose the fan-shaped locking bodies that have inclined surfaces that are substantially parallel to the inclined surfaces of the above-mentioned guide body and face each other with a slight gap between the inclined surfaces. The feature is that the angle formed is larger than the regular opening and closing angle.

[0005]

[Action]

 If an attempt is made to insert the grill at a predetermined angle or less by mistake, the outer periphery of the locking portion 8 will come into contact with the outer periphery of the guide portion 7, and the rotary shaft 4 will stop at a position where it does not reach the bottom of the notch 6, and the weight of the grill will be lost. Alternatively, the closing force pushes the rotary shaft 4 against the front wall of the notch 6 with the contact point as the fulcrum. Here, the inclined surface 8a of the locking portion 8 which is the fulcrum and the inclined surface 7a of the guide portion 7 are in line contact with each other, and the direction of the force pressing the fulcrum and the contact line direction are inclined. Due to the component force, these two members slide and deform the support plate 5 and the arm 3 in the direction of separating them. Due to this deformation, the force for pressing the rotary shaft 4 against the notch 6 is reduced to prevent breakage and the arm side falls by its own weight, and the rotary shaft reaches a predetermined position.

[0006]

【Example】

 An embodiment of a grill mounting device for an air conditioner according to the present invention will be described below with reference to FIGS. 1 and 2. 1 is a plan view of the present apparatus, and FIG. 2 is a view taken along the line AA of FIG. As shown in the figure, the main body 1 has a filter (not shown) on the front surface, and the front thereof is covered with a grill 2. A pair of arms 3 projecting rearwardly is provided on the upper part of the grill 2 with a rotary shaft 4 in the longitudinal direction of the grill, and a shaft hole 9 for inserting the rotary shaft 4 into a pair of support plates 5 is formed at the upper front part of the main body 1. The cutouts 6 are continuously provided above the cutouts. The shape of the notch 6 is such that the front part is inclined vertically and the rear part is inclined rearward so that the rotary shaft 4 can be easily attached and detached. The support plate 5 is surrounded by a shaft hole 9 as a center, a fan-shaped guide body 7 having an inclined surface 7a is provided at a position lower than the shaft center, and the arm 3 is surrounded by the rotary shaft 4 as a center. Then, the fan-shaped locking bodies 8 having the inclined surface 8a substantially parallel to the inclined surface 7a of the guide body 7 are made to face each other with a slight gap between the inclined surfaces, and the overlapping of both inclined surfaces is the axial center. The angle to make is larger than the regular opening and closing angle. According to this embodiment, the angle formed by the overlap between the inclined surfaces with respect to the axis is 90 degrees, and the normal opening / closing angle is about 40 degrees.

Therefore, when locking the grill 2 to the main body 1, first, as shown by the chain double-dashed line, the grill 2 is rotated about 90 degrees from the closed position to make the arm 3 substantially vertical and the rotary shaft 4 to be rotated. When it is lowered along the front part of the notch 6, the rotary shaft 5 coincides with the shaft hole 9 and the lower part of the locking part 8 is located in front of the upper part of the guide part 7 with a gap, so that the grill 2 is rotated. Then, the closed position shown by the dotted line and the solid line is obtained. If the grill 2 is lowered to an angle smaller than the position indicated by the chain double-dashed line, the inclined surface 8a of the locking portion 8 contacts the inclined surface 7a of the guide portion 7, and the rotary shaft 4 comes to the bottom of the notch 6. It stops at a position where it does not reach, and the rotating shaft 4 is pressed against the front wall of the notch 6 by the contact point as the fulcrum due to the weight of the grill. Here, the inclined surface 8a of the locking portion 8 which is the fulcrum and the inclined surface 7a of the guide portion 7 are in line contact, and the direction of the force pressing the fulcrum and the contact line direction are inclined, so that the contact line direction Due to the component force, these two members slide and deform the support plate 5 and the arm 3 in the direction of separating from each other. Due to this deformation, the force pressing the rotary shaft 4 against the notch 6 is reduced to prevent breakage, and the arm 3 side falls due to its own weight, and the rotary shaft 4 reaches a predetermined position so that the grill 2 is rotated and closed. To the position. Once the rotating shaft 4 is locked to the support plate 5, the guide portion 7 is normally engaged even if the grill 2 is moved in any direction other than rotation within the range in which the grill 2 is opened for filter replacement. Since the movement is blocked by the stopper 8, it does not fall off.

[0008]

[Effect of device]

 As described above, according to the present invention, the support plate 5 is surrounded by the shaft hole 9 and the fan-shaped guide body 7 having the inclined surface 7a is provided at a position lower than the shaft center. Is a fan-shaped locking body 8 which surrounds the rotating shaft 4 and has an inclined surface 8a which is substantially parallel to the inclined surface 7a of the guide body 7 and has a slight gap between the inclined surfaces. Since the angle formed by the overlap of both inclined surfaces with respect to the shaft center is larger than the normal opening and closing angle, there is no risk of breaking the rotating shaft even if the grill 2 is inserted at a position other than the specified angle. When it is inserted, it can be locked very easily by two operations of descending and rotating, and it does not fall off at the normal rotation angle, which is an excellent effect.
