[0029] Hereinafter, a window blind and a motor control device according to an embodiment of the present invention will be described in detail with reference to the drawings.
[0030] Implementation method 1.
[0031] Figure 1 1 is a perspective view of the motor control device according to Embodiment 1. The motor control device 50 includes a housing 60, a motor control unit 70, a blower 80, and a louver 51. The motor control device 50 sends a drive signal from the motor control unit 70 housed inside the housing 60 to a motor (not shown) connected to the motor control device 50 to control the operation of the motor.
[0032] A plurality of vents 61 are formed in the frame 60. Air can flow into the frame 60 through the vents 61 and can flow out of the frame 60. The blower 80 is accommodated in the frame 60. The blower 80 is driven, so that air flows in the frame 60, and the air flows in and out of the frame through the vents 61. The air flows in the frame 60, thereby cooling the heat generating components such as the motor control unit 70.
[0033] The shutter 51 is attached to the vent 61 . The shutter 51 is provided to prevent water from entering the interior of the frame 60 through the vent 61 .
[0034] Figure 2 This is a front view of the blind according to Embodiment 1. Figure 3 This is a perspective view of the blind according to the first embodiment. Figure 4 Yes Figure 3The A part shown is an enlarged partial oblique view. Figure 5 Observed from below Figure 4 An enlarged portion of the diagram is shown. Figure 6 is through Figure 2 The sectional view of the shutter is shown along the line BB. Figure 7 Yes Figure 6 The C portion shown is an enlarged partial cross-sectional view.
[0035] The louver 51 has a plate wall 1, a louver wall 2, and a side wall 4. The plate wall 1 is a plate-shaped member that covers the entire vent 61. An opening 1A is formed in the plate wall 1. The opening 1A is formed in the plate wall 1 in a manner that passes through from the surface 1b of the plate wall 1 to the back surface 1c. The louver wall 2 is a partition wall that divides the opening 1A formed in the plate wall 1 up and down. The opening 1A is divided up and down by the louver wall 2, thereby being divided into a plurality of small openings 1a. In addition, in the following description, the direction from the back surface 1c of the plate wall 1 toward the surface 1b is set as the front, and the direction from the surface 1b toward the back surface 1c is set as the rear (refer to Figure 6 ). In addition, the direction from the back side 1c of the plate wall 1 toward the surface 1b is set as the front-back direction, the direction perpendicular to the front-back direction is set as the up-down direction, and the direction parallel to the surface 1c of the plate wall 1 is set as the plane direction. In addition, in each figure, the front-back direction is represented by the X-axis, the up-down direction is represented by the Y-axis, and the plane direction is represented by the Z-axis. In the following, the positive direction of the X-axis is the front, and the negative direction is the back. The positive direction of the Y-axis is the top, and the negative direction is the bottom.
[0036] The louver wall 2 protrudes forward from the surface 1b of the plate wall 1. The louver wall 2 has an inclination that is more downward as it is away from the surface 1b. That is, the louver wall 2 has an inclination that is lower than the end (upper end 2e) on the back side 1c of the plate wall 1 from the back side 1c to the surface 1b in the up-down direction perpendicular to the front-back direction from the back side 1c of the plate wall 1 to the surface 1b, and one end (lower end 2d) on the surface 1b side is lower than one end (upper end 2e) on the back side 1c side. Moreover, the louver wall 2 is set to cover a part of the small opening 1a when viewed from the front side as viewed from the surface 1b side. That is, the louver wall 2 is set to overlap with at least a part of the opening 1A when viewed from the surface 1b side. Moreover, the louver wall 2 is set to intersect with the up-down direction and extend along a plane direction parallel to the surface of the plate wall 1. In the present embodiment 1, the louver wall 2 is set to extend along a plane direction that intersects perpendicularly with the up-down direction. Thus, water splashing toward the small opening 1a collides with the louver wall 2, and is prevented from entering the interior of the frame 60. Alternatively, the louver wall 2 may be provided so as to cover the entirety of the small opening 1a when viewed from the front.
[0037] A side wall 4 is provided on the side of the louver wall 2. The side wall 4 is a wall connecting the end 2a of the louver wall 2 and the edge of the opening 1A. That is, the side wall 4 is provided to abut against the end of the louver wall 2 in the plane direction. The side wall 4 can prevent water from entering the interior of the frame 60 from the side of the small opening 1a.
[0038] like Figure 5 As shown, the downward-facing surface of the louver wall 2, i.e., one surface 2b, and the inner surface 4a of the side wall 4 are in a positional relationship in which the angle formed by the one surface 2b and the inner surface 4a is a right angle. That is, the angle formed by the one surface 2b and the inner surface 4a here can be said to be an angle obtained at the intersection of an imaginary surface obtained by extending the downward-facing surface of the louver wall 2, i.e., one surface 2b, and an imaginary surface obtained by extending the inner surface 4a of the side wall 4. An inclined portion 5 is provided at the connection portion between the one surface 2b of the louver wall 2 and the inner surface 4a of the side wall 4, and the inclined portion 5 has a surface 5a that forms an obtuse angle with the one surface 2b of the louver wall 2.
[0039] Reference Figure 7 , the case where the water blown onto the louver wall 2 adheres to the back of one surface 2b, that is, the second surface 2c, is described. The water attached to the second surface 2c flows down along the inclined surface of the second surface 2c toward the front and gathers at the lower end 2d of the louver wall 2, and falls from the lower end 2d. Here, when the louver wall 2 is horizontal when viewed from the front, the water falls from the lower end 2d of the louver wall 2, but when any end 2a of the louver wall 2 is lower than the other end 2a, such as when the motor control device 50 is inclined, the water gathered at the lower end 2d continuously flows toward the end 2a lowered along the lower end 2d.
[0040] Moreover, when the inclined portion 5 is not provided at the connection portion between one side 2b of the louver wall 2 and the inner side surface 4a of the side wall 4, water that flows to the end 2a sometimes collides with the inner side surface 4a of the side wall 4 and scatters to the surroundings, or changes direction and flows toward the inside of the frame 60. A part of the water that scatters to the surroundings will scatter toward the inside of the frame 60. Therefore, there is a possibility that water will invade into the inside of the frame 60 from near the lower end 2a. In the present embodiment 1, the inclined portion 5 is provided at the connection portion between one side 2b of the louver wall 2 and the inner side surface 4a of the side wall 4, and the inclined portion 5 has a surface 5a that forms an obtuse angle with the one side 2b of the louver wall 2. Therefore, in Figure 5 The flow of water is represented by arrows, such as Figure 5 As shown, the water potential of the water flowing toward the end 2a and the inner side 4a can be weakened. Thus, the scattering of water when colliding with the inner side 4a and the change of the direction of the water flowing down toward the inner direction of the frame 60 can be suppressed, and the water is discharged from the front to prevent the intrusion of water into the frame 60.
[0041] Figure 8is a diagram showing a modified example of the blind according to the first embodiment, which is equivalent to Figure 4 Figure. Figure 8 As shown, the surface 5a of the inclined portion 5 may include a plurality of surfaces 5a1 and 5a2 having different angles. In addition, the number of surfaces having different angles included in the inclined portion 5 is not limited to two, and may be three or more.
[0042] In addition, if Figure 7 As shown, the inclined portion 5 may be provided starting from the lower end 2d and not reaching the upper end 2e. In addition, the inclined portion 5 may be provided on the entirety of the louver wall 2 from the lower end 2d to the upper end 2e.
[0043] Implementation method 2.
[0044] Fig. 9 It is a front view of the blind involved in Embodiment 2. Fig.10 It is a perspective view of the blind involved in Embodiment 2. Fig.11 Yes Fig.10 The D portion shown is an enlarged partial oblique view. Fig.12 Observed from below Fig.11 An enlarged portion of the diagram is shown. Fig.13 is through Fig. 9 The sectional view of the shutter is shown along the line EE. Fig.14 Yes Fig.13 The enlarged partial cross-sectional view of the enlarged F part shown. The same reference numerals are given to the same structures as those in the first embodiment, and detailed descriptions are omitted. In addition, in the second embodiment, the direction from the back side 1c of the plate wall 1 toward the surface 1b is set as the front-to-back direction, the direction perpendicular to the front-to-back direction is set as the up-down direction, and the direction parallel to the surface 1c of the plate wall 1 is set as the plane direction. In addition, in each figure, the front-to-back direction is represented by the X-axis, the up-down direction is represented by the Y-axis, and the plane direction is represented by the Z-axis. In the following, the positive direction of the X-axis is the front, and the negative direction is the back. The positive direction of the Y-axis is the top, and the negative direction is the bottom.
[0045] like Fig.13As shown, in Embodiment 2, the louver wall 2 does not protrude from the surface 1b of the plate wall 1, and is accommodated between the surface 1b and the back surface 1c of the plate wall 1. In addition, similarly to Embodiment 1, the louver wall 2 has an inclination that decreases forward, and one end on the surface 1b side of the plate wall 1 becomes the lower end 2d. Furthermore, in Embodiment 2, the louver wall 2 is also configured to overlap with at least a portion of the opening 1A when viewed from the surface 1b side. Furthermore, the louver wall 2 is configured to intersect with the up-down direction and extend in a planar direction parallel to the surface 1b of the plate wall 1. In addition, the louver wall 2 is configured to extend in a planar direction that intersects perpendicularly to the up-down direction. In Embodiment 2, the surface of the louver wall 2 that faces upward becomes a surface 2b. As Fig.12 As shown, the upward-facing surface of the louver wall 2, i.e., one surface 2b, and the edge of the opening 1A, i.e., the inner surface 1A1, are in a positional relationship in which the angle formed by the one surface 2b and the inner surface 1A1 is a right angle. That is, the angle formed by the one surface 2b and the inner surface 1A1 here can be said to be an angle obtained at the intersection of an imaginary surface obtained by extending the upward-facing surface 2b of the louver wall 2 and an imaginary surface obtained by extending the edge of the opening 1A, i.e., the inner surface 1A1. The inclined portion 5 is provided at the connection portion between the upward-facing surface 2b and the edge of the opening 1A, i.e., the inner surface 1A1. That is, in the second embodiment, the edge of the opening 1A becomes the wall portion with which the louver wall 2 abuts.
[0046] When the louver wall 2 is disposed between the front surface 1b and the back surface 1c of the plate wall 1 as in Embodiment 2, when one end 2a of the louver wall 2 is lower than the other end 2a, water attached to the louver wall 2 also flows on the upper surface, i.e., one surface 2b, toward the lower end 2a. In Embodiment 2, the inclined portion 5 is provided on the upper surface, i.e., one surface 2b, so that the water force of the water colliding with the inner surface 1A1 can be reduced, and water can be prevented from intruding into the interior of the frame 60.
[0047] Fig.15 FIG. 1 is a diagram showing a first modified example of the louver wall that can be applied to Embodiment 1 and Embodiment 2. Fig.15 As shown, the louver wall 2 can be configured to have a width that becomes wider from the upper end 2e toward the lower end 2d toward one end 2a of the louver wall along the plane direction in which it extends. By configuring as described above, the width of the flow path of water flowing on the louver wall 2 can be expanded, the flow rate of water flowing on the louver wall 2 can be reduced, and the water potential of the water colliding with the inner side surfaces 1A1 and 4a can be weakened.
[0048] Fig.16 FIG. 2 is a diagram showing a second modified example of the louver wall that can be applied to Embodiment 1 and Embodiment 2. Fig.16As shown, the louver wall 2 can be configured to have a width that becomes narrower from the upper end 2e toward the lower end 2d toward the two ends of the louver wall along the plane direction in which it extends. By configuring as described above, water easily falls from the front end of the widest part of the central portion, and the water flowing toward the end 2a can be reduced, and the water force of the water colliding with the inner side surfaces 1A1 and 4a can be weakened.
[0049] Fig.17 FIG. 3 is a diagram showing a third modified example of the louver wall that can be applied to Embodiment 1 and Embodiment 2. Fig.17 As shown, a plurality of concave-convex portions 6 can be provided at the lower end 2d of the louver wall 2. The direction of the concave-convex portions 6 is parallel to the direction from the upper end 2e toward the lower end 2d. In addition, the shape of the concave-convex portions 6 is square. By configuring as described above, water can easily fall on the convex portion, and the water flowing toward the end 2a can be reduced, and the water force of the water colliding with the inner side surfaces 1A1 and 4a can be weakened. The concave-convex portions 6 can be provided on the entire lower end 2d, or can be provided on only a portion.
[0050] Fig.18 2 is a diagram showing a fourth modified example of the louver wall that can be applied to the first and second embodiments. Fig.18 As shown, a plurality of concave and convex portions can be provided at the lower end 2d of the shutter wall 2. The direction of the concave and convex portions is parallel to the direction from the upper end 2e toward the lower end 2d. In addition, the shape of the concave and convex portions is a triangle. By configuring as described above, water can fall more easily from the front end of the convex portion, and the water flowing toward the end 2a can be reduced, thereby weakening the water potential of the water colliding with the inner side surfaces 1A1 and 4a. The concave and convex portions 6 can be provided on the entire lower end 2d, or on only a portion thereof. In addition, the square concave and convex portions 6 and the triangular concave and convex portions 6 can be combined.
[0051] Fig.19 FIG. 5 is a diagram showing a fifth modified example of the louver wall that can be applied to Embodiment 1 and Embodiment 2. Fig.19 As shown, a plurality of concave and convex portions can be provided at the lower end 2d of the louver wall 2. The direction of the concave and convex portions is perpendicular to one side 2b. In addition, the shape of the concave and convex portions is a square. By configuring as described above, water can easily fall in the concave portion, and the water flowing toward the end portion 2a can be reduced, and the water potential of the water colliding with the inner side surfaces 1A1 and 4a can be weakened. In addition, the shape of the concave and convex portions can be a triangular shape.
[0052] Fig. 20 2 is a diagram showing a modified example of the blinds according to Embodiment 2. Fig. 20 As shown, the louver wall 2 is inclined so that in the initial state, one end 2a is lower than the other end 2a. That is, the louver wall 2 is arranged to intersect the up-down direction and extend in a plane direction parallel to the surface 1b of the plate wall 1. Fig. 20In the illustrated variation, the plane direction in which the louver wall 2 extends intersects the up-down direction, but unlike the second embodiment, does not intersect perpendicularly with the up-down direction. In this case, the upward-facing surface of the louver wall 2, i.e., one surface 2b, and the inner surface 1A1 of the opening 1A are in a positional relationship in which the angle formed by the one surface 2b and the inner surface 1A1 is an acute angle. In the above case, by providing an inclined portion 5 having a surface 5a at the connection portion between the one surface 2b and the inner surface 1A1, the water potential of the water colliding with the inner surface 1A1 can be weakened, thereby preventing the water from penetrating into the interior of the frame 60. In addition, if the angle formed by the one surface 2b of the louver wall 2 and the surface 5a of the inclined portion 5 is larger than the angle formed by the one surface 2b and the inner surface 1A1, the effect of weakening the water potential of the colliding water can be obtained.
[0053] In addition, Fig. 20 The louver wall 2 that does not protrude from the surface 1b of the plate wall 1 is illustrated in the example, but the louver wall 2 that protrudes from the surface 1b is illustrated in the first embodiment, and may be inclined in the initial state similarly to the present modification.
[0054] In addition, in Embodiments 1 and 2, the surface roughness of one side 2b, the lower end 2d of the louver wall 2, and the surface 1b of the plate wall 1 can be made rougher. As a result, the surface tension between the water in contact with one side 2b, the lower end 2d of the louver wall 2, and the surface 1b of the plate wall 1 increases, and the flow rate of the flowing water can be slowed down to prevent the water from entering the interior of the frame 60.
[0055] The configuration described in the above embodiment is merely an example, and may be combined with other known technologies, the embodiments may be combined with each other, and part of the configuration may be omitted or changed without departing from the gist.
