Description

  The present invention relates to a blower having a feature in an angle adjustment structure of a wind direction changing blade provided in an air blowing outlet for blowing air.

  The structure of the blowing part used for the floor-standing type air conditioner having a conventional vertically long box-shaped housing will be described with reference to FIGS.

  In the figure, reference numeral 1 denotes an air conditioner main body, which is composed of a suction port 2 provided in the lower front portion, a blowout panel 3 provided in the upper front portion, a rear panel 4 forming the rear surface, a front panel 5 on the front surface, and the like. Yes. A casing 6 is attached to the lower part of the rear panel 4. A motor 7 having one end supported by the rear panel 4 is accommodated in the casing 6, and a fan 8 is mounted on the other end of the motor 7 and the tip of the shaft. Has been. 6a is a casing suction port facing the suction port 2, 6b is a casing outlet opening toward the upper part inside the main body, and 9 is a heat exchanger disposed above the casing 6 and inclined toward the rear panel 4 side.

  In the blowout panel 3, reference numeral 11 denotes a vertical wind direction change blade for changing the wind direction in the vertical direction of the blown wind provided in substantially the entire width direction of the blowout panel 3, and reference numeral 12 denotes a horizontal direction provided in substantially the entire length in the vertical direction of the blowout panel 3. It is a right and left wind direction changing blade that changes the wind direction.

  4 and 5 are main parts of the blowout panel 3. FIG. Reference numeral 13 denotes a connecting bar for connecting the ends of the plurality of up-and-down air direction changing blades 11. When one up-and-down air direction changing blade 11 is operated up and down, the plurality of up-and-down air direction changing blades 11 move simultaneously. In FIG. 5, the connecting bar 13 is provided with a concave shape 13a in a part of an arc shape. On the side surface of the blowout panel 3, a protruding portion 3 a is disposed at a location facing the arc of the connecting bar 13. The protrusion 3a of the blow-out panel 3 meshes with the concave shape 13a of the connecting bar 13 to support the up / down air direction changing blade 11 at a specified angle.

In another device, an engagement piece is integrally provided on the blow-out panel 3, and a recessed portion that engages with a stopper piece (not shown) provided on the shaft 11 a formed on the left and right ends of the up-and-down wind direction changing blade 11 is provided here. A device that is formed and intended to fix the inclination angle of the up-and-down airflow direction changing blade 11 to a user-desired angle is disclosed (Patent Document 1).
Japanese Utility Model Publication No. 64-28740 (Fig. 2 etc.)

  However, in the above-described conventional configuration, if the projections on the side surfaces of the blow-out panel 3 are formed integrally with the frame that forms the blow-out port, the molding die becomes complicated and the processing man-hours are likely to increase.

  Further, when the angle of the up / down airflow direction changing blade 11 is frequently changed or when it is used for a long period of time, the protruding portion on the side surface of the blowout panel 3 is worn, or the protruding portion may be damaged in some cases. If it becomes difficult to maintain the angle of the up-and-down wind direction changing blades 11, it is necessary to replace the blowout panel 3 main body, and there is a problem that a considerable cost may be required for repair.

The present invention solves such a conventional problem, and wear / breakage of a portion that is used to adjust the angle of a wind direction deflecting blade by engaging with a connecting bar that connects end portions of a plurality of up and down wind direction changing blades. It is an object of the present invention to provide a blower configured without incurring high repair costs.

  In order to solve the above-described problems, the present invention is configured such that the protrusions of the blowout panel are separate parts (support members) and have a large number of contact portions with the connecting bar.

  With the support member, an inexpensive blow-out panel can be produced and can be supplied at a low cost even when consumable parts are replaced.

  As is apparent from the above, the present invention has a single component as a part related to the operating force of the up / down changing blade and a plurality of contact parts. According to this configuration, the blade operating force change due to the thermal deformation of the cooling / heating is reduced. In addition to preventing, there are the effects of supplying inexpensive molds and low-priced parts.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a main part configuration diagram of a floor-mounted air conditioner according to Embodiment 1 of the present invention.
In the figure, reference numeral 3 denotes a blow-out panel, and the wind that has passed through the heat exchanger is determined by the left-right wind direction change blade 12 that changes the wind direction in the left-right direction provided in substantially the entire length in the vertical direction. The vertical wind direction is determined by a plurality of vertical wind direction changing blades 11 provided substantially over the entire horizontal direction 3, and the wind is blown into the room. The upper and lower wind direction changing blades 11 are connected to both ends by a plurality of connecting bars 13. The support member 14 is inserted into the holes 3 a disposed on both side surfaces of the blow-out panel 3 using the elasticity of the resin, and has an integral shape with the blow-out panel 3. The connecting bar 13 is provided with a concave shape 13a in a part of an arc shape. The support member 14 is provided with convex protrusions 14 a at locations corresponding to the arc shape of the connecting bar 13. The convex protrusion 14a of the support member 14 is engaged with the concave shape 13a of the connecting bar 13 to support the up / down air direction changing blade 11 at a specified angle.

  By connecting the connecting bar 13 and the support member 14 that are consumables as single parts as in the above-described configuration, even if a state in which service parts need to be replaced occurs, it is not necessary to replace the blowout panel 3 that is a large part. In addition, it is possible to provide an inexpensive service that can be dealt with by replacing the support member 14 that is a small part.

(Embodiment 2)
FIG. 2 is a structural diagram of a blowout panel according to Embodiment 2 of the present invention. Convex shapes 13b are provided on both surfaces of a part of the connecting bar 13 that are concave and have a flat shape. Further, the support member 14 is provided with projections 14b that mesh with the concave shape 13a of the connecting bar 13, and convex shapes 14c and 14d that contact the convex shape 13b on both surfaces of the connecting bar 13. By having a mechanism for holding the movement of the connecting bar 13 on the three surfaces of the support member 14 in this way, when the length change of the up / down airflow direction changing blade 11 occurs due to the heat effect of air conditioning, the part related to the contact portion Since there are a plurality of parts where the connecting bar 13 and the support member 14 come into contact with each other even if the frame is thermally deformed, it is possible to maintain the angle of the up-and-down wind direction changing blade 11 on any of a plurality of surfaces even if there is a variation in component dimensions or assembly. The operating force of the upper and lower blades with no variation is obtained.
