Box-shaped fans are generally box-shaped and have a circular wind direction changing grille on the front side of the ventilation path of the case. The wind direction changing grill rotates forward or backward in the direction of force applied by a drive device, thereby changing the direction of the air flow formed by the blades, that is, the direction of the air blowing. It functions almost the same as the oscillating device in a type of electric fan. However, in the conventional type, the wind direction changing grille was attached using a mounting device with a structure as shown in Figure 1, so it could easily come loose depending on the direction of rotation, and there was a problem with the stability of the attached state. .
That is, conventionally, the boss portion 102 formed at the center of the wind direction changing grille 101 is integrated with the case and is fitted into a cylindrical sliding portion 103 that protrudes forward from the center of the ventilation path. The boss portion 102 is held down from the outside by hooking and attaching a grill knob 105 equipped with a leaf spring 104 to the sliding portion 103. The grill knob 105 is latched by fitting the leaf spring 104 into the sliding portion 103 and rotating it in one direction so that the spring force acts on the wind direction changing grille 101. There is no structure on the sliding portion 103 side that restricts rotation toward the loosening side or the detachment side, which is the opposite. Therefore, at the time when the direction of rotation of the wind direction changing grill 101 is changed, the rotational force toward the loosening side or the detaching side is applied to the grill knob 105 in a state where it is dragged by the wind direction changing grill 101.
This rotational force may cause the grill knob 105 to loosen or come off.

The box-shaped electric fan as an example of application of the present invention shown in FIG. 2 has a ventilation passage extending from the front to the back formed in the center of a slightly flat rectangular box-shaped case 3, which is a joined body of a front case 1 and a back case 2. A fan motor 5 that rotates the blades 4 is disposed in S, a wind direction changing grill 6 that is rotated by a drive device provided in the case 3 is provided on the front side of the ventilation passage S, and a blade guard 7 is provided on the back side. are installed respectively. The upper part of the case 3 is provided with operation parts such as a push button switch 8, and a pair of stands 9 are attached to the left and right sides of the lower part.
This allows it to be placed on the floor in a standing position. The fan motor 5 is supported by four mounting legs 10 that are integral with the front case 1 and protrude into the ventilation path S along the diagonal of the front case 1. The four mounting legs 10 are formed to have a streamlined cross-sectional shape, and the motor lead wire 11 of the fan motor 5 is housed in a concave portion on the leeward side of one of the four mounting legs 10. The protruding ends of the four mounting legs 10 in the ventilation path S are connected at the center of the ventilation path S, and the fan motor 5 is attached to the mounting plate 1 on the back side.
A motor mounting plate 13 for mounting via 2,
A grille attachment part 14 is formed on the front side to which the wind direction changing grille 6 can be rotatably fitted. The fan motor 5 is fixed to the motor mounting portion 13 via the mounting plate 12 with the rotating shaft protruding backward, and the blades 4 are fixed to the motor mounting portion 13 through the mounting plate 12.
is installed. The wind direction changing grille 6 has a metal part 15 at the center that functions as a bearing and serves as a rotation center.
The metal part 15 is fitted into the cylindrical sliding part 18 of the grill attachment part 14 and is attached to the grill attachment part 14. By doing so, the ventilation path S
It is rotatably attached to the front part of the A drive roller of a drive device is pressed against the inner peripheral surface of the outer ring portion 16 of the wind direction changing grille 6, and can rotate in either forward or reverse direction under the rotational force of the drive roller. The rotation direction of the wind direction changing grille 6 is specified by the direction of the force applied to the wind direction changing grille 6, and the drive device or the switch that operates it does not have a function of specifying the rotation direction. The installation of the wind direction changing grille 6 to the sliding part 18 is performed using the sliding part 1.
8 and a grill knob 19 that constitutes a grill mounting device.
This is done by attaching it to the sliding part 18. That is, the inner peripheral surface of the sliding part 18 is formed with a holding part 20 that is divided into three parts in the circumferential direction and protrudes inward, and three holding parts 21 are fixed to the back surface of the grill knob 19 so as not to rotate. A star-shaped leaf spring 22 that protrudes radially is inserted into the sliding part 18 through the space 23 between the holding parts 20, and the grille knob 19 is turned in one direction to separate each clamping piece of the leaf spring 22. 21 is brought into contact with the sliding surface 24 on the rear side of the holding part 20 and is latched. The spring force of the leaf spring 22 acts on the grill knob 19, and presses the metal part 15 of the wind direction changing grille 6, which has the metal part 15 externally fitted onto the sliding part 18, from the outside. The sliding surface 24 of each holding part 20 of the sliding part 18 has a tapered part 25 for guiding on the tip side in a certain rotation direction, a stopper protrusion 26 for regulating rotation on the rear end, and a stopper projection 26 on the rear end. A holding recess 27 is formed in front of each projection 26 . Each clamping portion 21 of the star-shaped leaf spring 22 is formed with a convex portion 28 that locally protrudes to the front surface at the center and can be engaged with the holding recess 27. It is adapted to contact surface 24. The leaf spring 22 fitted into the sliding portion 18 is attached to the grill knob 1.
By rotating the stopper projection 9 in a certain direction, the tapered portion 25 contacts the sliding surface 24, and the stopper protrusion 2
6. At this time, the protrusions 28 of each clamping piece 21 of the leaf spring 22 engage with each holding recess 27 of the sliding surface 24. Thus, the rotation of the grill knob 19 in the direction of loosening or detachment is restricted by the engagement of the clamping piece 21 with the holding recess 27, and the spring force that presses down the metal part 15 of the wind direction changing grille 6 from the outside is applied. This prevents the wind direction changing grille 6 from rattling and coming off. The convex portion 28 of the clamping piece 21 engaged with the holding concave portion 27 is
If the grill knob 19 is rotated in the opposite direction from when it is installed, it will come out of the holding recess 27, but when the direction of rotation of the wind direction changing grill 6 changes, the rotational force that is transmitted to the grill knob 19 via the metal part 15 will be reduced. Depending on the action, it will not come out of the holding recess 27. Therefore, even if the rotational direction of the wind direction changing grill 6 is changed relatively frequently, the grill knob 19 will not loosen or come off, and the installed state of the wind direction changing grill 6 will be stable. be.

As is clear from the above description of the embodiments, the wind direction changing grill mounting device for a box-shaped electric fan of the present invention includes a cylindrical sliding part that externally fits the boss part, which is the center of rotation of the wind direction changing grill, and It is attached by a leaf spring attached to the back side of the board, and consists of a grill knob that presses the boss part from the outside. A tapered part has a guiding function for hanging the leaf spring, a stopper protrusion prevents excessive sliding of the leaf spring, and a holding recessed part stabilizes the hanging position of the leaf spring. Since the convex part of the holding piece of the leaf spring comes into sliding contact with the plate spring, it is possible to smoothly attach the grill knob to the sliding part. Stability is high under the action of rotational force in any direction, and no matter which direction the wind direction change grill rotates, the grille knob is prevented from loosening or coming off, increasing the stability of the installed state of the wind direction change grill. can do.
