FIG. 4 is a partial cross-sectional view showing a mounting structure 130 in a state where the decorative panel 120 is mounted on the orifice 109, which will be described later, in the ventilation fan 10 according to the first embodiment of the present invention.

As shown in FIG. 1, the ventilation fan 10 according to the first embodiment includes a ventilation fan main body 101, an electric motor 105, a fan 107, a shutter 108, a decorative panel 120, and a member to be attached to which the decorative panel 120 is attached. It mainly comprises a functioning orifice 109. The ventilation fan 10 is attached to a ventilation port hole provided in the wall of the living room to ventilate the indoor air and the outdoor air. In the following, when the configuration of the ventilation fan is described, the thickness direction of the wall to which the ventilation fan is attached is also described as the z-axis direction. Regarding the z-axis direction, the direction from the outdoor side to the indoor side is the positive direction, and the opposite direction is the negative direction. Further, the two directions orthogonal to the z-axis direction are also described as the x-axis direction and the y-axis direction, respectively. With the ventilation fan mounted on the wall, the vertical direction is the y-axis direction and the horizontal direction is the x-axis direction.

The ventilation fan main body 101 is a member having a substantially square cylinder shape, in which openings (main body openings 102a and 102b) are provided on two opposing surfaces. The ventilation fan main body 101 is formed of a metal material, a resin material, or the like so as to have strength to support the entire ventilation fan 10. When a metal material is used, the ventilation fan main body 101 may be formed by combining metal plates. The ventilation fan main body 101 is fitted into a ventilation port hole provided in the wall of the living room so that the main body openings 102a and 102b face the indoor space and the outdoor space, respectively. A flange 103 is formed on the edge of the main body opening 102a on the indoor side of the ventilation fan main body 101 so as to project along the wall toward the outside of the main body opening 102a. A flange-side hooked portion 104 having a stepped shape is provided in a part of the flange 103 region on which the orifice-side hooked portion 112 of the orifice 109, which will be described later, is hooked. In the illustrated example, the ventilation fan main body 101 has a substantially square tubular shape, but the first embodiment is not limited to such an example. For example, the ventilation fan main body 101 may have a substantially cylindrical shape.

Inside the ventilation fan main body 101, the electric motor 105 is arranged so that the rotation shaft 106 is substantially parallel to the z-axis direction and protrudes toward the indoor side. Inside the ventilation fan main body 101, an electric motor fixing leg 115, which is a member for supporting the electric motor 105, is extended in a substantially H shape. The electric motor 105 is fixed to the center of the substantially H-shape of the electric motor fixing leg 115 by a screw or the like. The portion corresponding to the substantially H-shaped vertical bar is extended inside the ventilation fan main body 101 so that both ends thereof are connected to the facing inner walls of the ventilation fan main body 101. The shape of the motor fixing leg 115 is not limited to this example. The electric motor fixing legs 115 may have any shape as long as the electric motor 105 can be fixed in the ventilation fan main body 101 at a desired position and posture. For example, the motor fixing leg 115 may be substantially I-shaped or radial.

When the ventilation fan 10 is mounted on the wall, the fan 107 is rotated by the electric motor 105, so that the air on the indoor side flows to the outside of the room through the main body openings 102a and 102b of the ventilation fan main body 101, and ventilation is performed. Will be

The outdoor main body opening 102b of the ventilation fan main body 101 is provided with a plurality of plate-shaped shutters 108 for opening and closing the main body opening 102b. Each of the shutters 108 is configured to be rotatable around one side corresponding to the upper side of the plate shape as a rotation axis. When the fan 107 rotates, each of the shutters 108 rotates about the rotation axis due to the wind pressure of the ventilation flow generated by the fan 107, and is oriented sideways (that is, its plate surface is substantially parallel to the z-axis direction). It becomes. This opens the air passage. On the other hand, when the fan 107 is stopped, each of the shutters 108 rotates downward due to its own weight (that is, its plate surface is substantially orthogonal to the z-axis direction), and the air passage is closed.

By providing the shutter 108, it is possible to prevent the intrusion of outside air and rainwater due to the wind. The opening / closing method of the shutter 108 is not limited to the wind pressure type described above, and may be, for example, a mechanical type. Further, the number of shutters 108 is not limited and may be arbitrarily determined.

An orifice 109 is detachably provided on the indoor surface of the ventilation fan body 101. The orifice 109 is provided with an orifice main body 110 which is a plate-shaped member having a substantially square surface, an orifice side hook 112 for attaching the orifice 109 to the ventilation fan main body 101, and a decorative panel 120 attached to the orifice 109. It has an orifice side mounting portion 141 for the purpose. The structure of the orifice side mounting portion 141 will be described in detail later.

The four sides of the orifice body 110 are bent in a direction substantially perpendicular to the plate surface. As shown in FIG. 2, the bent portion of the orifice main body 110 is provided with an orifice-side hook 112 that projects inward. The orifice main body 110 is arranged so as to cover the main body opening 102a of the ventilation fan main body 101 together with the flange 103, and the orifice side hook 112 is hooked to the flange side hook 104 of the flange 103. Thereby (specifically, the orifice-side hooking portion 112 formed of the convex portion is hooked on the step of the flange-side hooked portion 104), the orifice 109 is attached to the ventilation fan main body 101.

The orifice main body 110 is provided with an orifice opening 111 at a portion facing the fan 107 when the orifice 109 is attached to the ventilation fan main body 101. When the orifice 109 is attached to the ventilation fan body 101, the gap between the ventilation fan body 101 and the fan 107 is closed by the plate surface of the orifice body 110, and only the portion of the ventilation fan body 101 facing the fan 107 is opened. It will be opened by the portion 111. With such a configuration, the orifice opening 111 functions as a wind tunnel for efficiently circulating air to the fan 107. In the present specification, regarding the orifice 109, the indoor side thereof may be described as the first side, and the opposite side of the first side may be described as the second side.

The configuration of the ventilation fan 10 described above may be the same as that of a general ventilation fan. In other words, as the configuration of the ventilation fan 10 described above, various known configurations used in a general ventilation fan may be applied.

A decorative panel 120 is attached to the first side of the orifice 109 so as to cover the main body opening 102a of the ventilation fan main body 101 and the orifice opening 111 of the orifice 109. The decorative panel 120 has a panel main body portion 121 which is a plate-shaped member having a substantially square surface, and a panel side mounting portion 151 for attaching the decorative panel 120 to the orifice 109. The structure of the panel-side mounting portion 151 will be described in detail later.

The panel main body 121 is provided with a striped grid (striped in the y-axis direction in the illustrated example) extending in one direction on one surface. Air circulates through the gaps in the grid to provide ventilation. Since the decorative panel 120 makes it difficult for the members inside the ventilation fan main body 101 (for example, the electric motor 105 and the fan 107) to be visually recognized from the indoor side through the orifice opening 111 and the main body opening 102a, the ventilation fan 10 It becomes possible to improve the design of the.

The ventilation fan 10 includes a mounting structure 130 for attaching the decorative panel 120 to the orifice 109. Hereinafter, the mounting structure 130 will be described in detail with reference to FIGS. 2 to 4.

The mounting structure 130 includes a panel-side mounting portion 151 provided on the decorative panel 120 (corresponding to the first mounting portion of the present invention) and an orifice-side mounting portion 141 provided on the orifice 109 (second mounting portion of the present invention). Corresponds to) and.

The orifice-side mounting portions 141 are provided at positions corresponding to the four corners of the surface of the orifice main body 110, which is substantially square, facing the decorative panel 120. FIG. 2 shows a partial cross-sectional view of the ventilation fan 10 including one of the four orifice-side mounting portions 141. As shown in FIG. 2, the orifice side mounting portion 141 protrudes from the first side surface of the orifice main body 110 toward the first side (that is, from the surface facing the decorative panel 120). It has a boss portion 142 provided so as to project toward the decorative panel 120, and a through hole 143 provided so as to penetrate the orifice 109 while penetrating the inside of the boss portion 142 in the projecting direction. The boss portion 142 has a substantially cylindrical shape having a substantially constant thickness from the root to the tip and is provided with a substantially circular through hole 143 inside.

The orifice 109 can be formed by injection molding using a resin material. In this case, the orifice side mounting portion 141 may be integrally formed with the orifice main body portion 110 when forming the orifice 109. By forming them integrally, it is possible to reduce the manufacturing cost.

The panel-side mounting portion 151 is provided at positions corresponding to the orifice-side mounting portion 141 and corresponding to the four corners of the surface of the substantially square panel main body portion 121 facing the orifice 109. That is, in the first embodiment, it corresponds to the four corners of the substantially square panel body 121 facing the orifice body 110 and the substantially square orifice body 110 facing the panel body 121. The mounting structure 130 is provided at each of the mounting positions.

FIG. 3 shows one of the four panel-side mounting portions 151 as viewed from the side facing the orifice 109. As shown in FIG. 3, the panel-side mounting portion 151 has a boss portion 152 and a pair of claw portions 153 provided at the tip of the boss portion 152. In order to distinguish it from the boss portion 142 of the orifice side mounting portion 141, in this specification, the boss portion 152 of the panel side mounting portion 151 is described as the first boss portion, and the boss of the orifice side mounting portion 141 is described. The portion 142 may be referred to as a second boss portion.

The boss portion 152 has a substantially constant thickness from the root to the tip. A space is provided inside the boss portion 152, and the boss portion 152 has a substantially cylindrical shape with a bottom on the root side (that is, the plate surface side of the panel main body portion 121). The outer diameter of the boss portion 152 is adjusted to be slightly smaller than the inner diameter of the through hole 143 of the orifice side mounting portion 141.

The pair of claw portions 153 are formed so as to project outward in the radial direction of a substantially cylindrical shape at the tip of the boss portion 152. The tip of the boss portion 152 is provided with a notch other than the portion where the pair of claw portions 153 are provided. Due to the notch, the pair of claw portions 153 can be elastically deformed so that the pair of claw portions 153 can move in the radial direction of the substantially cylindrical shape of the boss portion 152 so as to approach each other.

The decorative panel 120 can be formed by injection molding using a resin material. In this case, the panel-side mounting portion 151 can be integrally formed with the panel main body portion 121 when forming the decorative panel 120. By forming them integrally, it is possible to reduce the manufacturing cost.

When the decorative panel 120 is attached to the orifice 109, the boss portion 152 of the panel side attachment portion 151 is inserted into the through hole 143 of the orifice side attachment portion 141 from the first side. The outer diameter of the portion of the boss portion 152 where the pair of claws 153 exists is larger than the inner diameter of the through hole 143 of the orifice side mounting portion 141, but as described above, the pair of claws 153 is the pair of claws 153. Since they can be elastically deformed so that they can move in the direction of approaching each other, the pair of claws 153 slide on the inner wall of the through hole 143 while causing such elastic deformation, and the boss portion 152 is formed through the through hole. It is inserted in 143.

The length of the boss portion 142 of the orifice side mounting portion 141 and the boss portion 152 of the panel side mounting portion 151 is a state in which the boss portion 152 of the panel side mounting portion 151 is inserted all the way into the through hole 143 of the orifice side mounting portion 141. The pair of claws 153 are adjusted so that they can be exposed to the second side of the orifice 109. As shown in FIG. 4, when the pair of claw portions 153 is exposed to the second side of the orifice 109, it returns from the elastically deformed state to the original state, and on the plate surface of the orifice main body 110 on the second side. Hang on. That is, the opening edge portion on the second side of the through hole 143 of the orifice side mounting portion 141 functions as a hooked portion on which the pair of claw portions 153 of the panel side mounting portion 151 are hooked. In this way, the decorative panel 120 is attached to the orifice 109 by hooking the pair of claws 153 of the panel side attachment portion 151 to the hooked portion of the orifice side attachment portion 141.

When removing the decorative panel 120 from the orifice 109, first, the orifice 109 is removed from the ventilation fan main body 101 with the decorative panel 120 attached. Since the orifice 109 is only attached by hooking the orifice side hooking portion 112 to the flange side hooking portion 104 of the flange 103 of the ventilation fan main body 101, it can be easily removed.

A pair of claws 153 of the panel-side mounting portion 151 of the decorative panel 120 are exposed on the second side of the orifice 109, and are hooked on the plate surface of the orifice main body 110 on the second side. The user picks the pair of claws 153 and elastically deforms the pair of claws 153 so as to approach each other in the radial direction of the boss 152, while attaching the boss 152 of the panel side mounting 151 to the orifice side mounting portion. The decorative panel 120 is moved relative to the orifice 109 so as to be pulled out of the through hole 143 of 141. As a result, the decorative panel 120 is removed from the orifice 109.

As described above, in the ventilation fan 10 according to the first embodiment, the mounting structure 130 for mounting the decorative panel 120 to the orifice 109 has a panel-side mounting portion 151 (first mounting portion) provided on the decorative panel 120 and an orifice. It has an orifice-side mounting portion 141 (second mounting portion) provided on the 109. The panel-side mounting portion 151 has a boss portion 152 (first boss portion) projecting toward the orifice 109, and a claw portion 153 provided on the boss portion 152. The orifice-side mounting portion 141 has a through hole 143 that communicates the first side and the second side of the orifice 109. Then, in the state where the decorative panel 120 is attached to the orifice 109, the boss portion 152 of the panel side attachment portion 151 is inserted into the through hole 143 of the orifice side attachment portion 141 from the first side, and the second of the orifice 109. The claw portion 153 of the panel side mounting portion 151 is exposed and hooked on the side of the panel. By having such a mounting structure 130, the user can mount the decorative panel 120 on the orifice 109 by simply inserting the boss portion 152 of the panel side mounting portion 151 into the through hole 143 of the orifice side mounting portion 141. Further, as described above, the user pulls out the boss portion 152 of the panel side mounting portion 151 from the through hole 143 of the orifice side mounting portion 141 while pinching the pair of claw portions 153 from the second side of the orifice 109. , The decorative panel 120 can be removed from the orifice 109.

As described above, according to the first embodiment, as compared with the mounting structure of the decorative panel (for example, the one mounted by a screw and the one which is fitted and killed) in a conventional general ventilation fan without using a tool. The decorative panel 120 can be easily attached and detached. Since the decorative panel 120 can be easily attached and detached, for example, a decorative panel 120 having various designs is prepared, and the user can appropriately replace the decorative panel 120 according to the interior of the living room. The method becomes possible. Since the decorative panel 120 can be replaced according to the user's preference, a ventilation fan 10 having a more excellent design can be realized. Further, since the decorative panel 120 can be easily removed from the orifice 109 and both of them can be cleaned individually, it is possible to maintain a clean state of the portion of the ventilation fan 10 located on the indoor side and visible to the user. it can. Therefore, a more aesthetically pleasing ventilation fan 10 can be realized.

In the present specification, "the claw portion 153 is exposed to the second side of the orifice 109" means that the claw portion 153 is exposed from the second side to the extent that the user can pick it up by hand. Means. In the first embodiment, the claw portion 153 is exposed to the second side of the orifice 109 and is hooked on the second side, so that the user can use the tool without using a tool as described above. The decorative panel 120 can be easily removed.

Here, in the first embodiment, in the ventilation fan 10, the surface of the substantially square panel body 121 facing the orifice body 110 and the surface of the substantially square orifice body 110 facing the panel body 121. Mounting structures 130 are provided at positions corresponding to the four corners. Therefore, even when the decorative panel 120 is rotated 90 degrees around the z-axis, the decorative panel 120 can be attached to the orifice 109 in the same manner as in the original state. As a result, when the design of the decorative panel 120 has directionality in the xy plane (that is, when the design of the decorative panel 120 changes when rotated about the z-axis), the user himself / herself. It is possible to appropriately select the orientation of the decorative panel 120 according to the preference and functionality of the decorative panel 120.

For example, in the case of the decorative panel 120 having a striped lattice extending in one direction as in the above-described configuration example, the extending direction of the lattice is changed by rotating the decorative panel 120 90 degrees around the z-axis. Can be done. For example, when the ventilation fan 10 is installed relatively upward and the user looks up at the decorative panel 120, the decorative panel 120 is attached so that the extending direction of the lattice is substantially parallel to the x-axis direction. Since the user's line of sight is easily blocked by the grid, the effect of making the internal members difficult to see is more exerted. That is, the design can be further improved. On the other hand, when the decorative panel 120 is attached so that the stretching direction of the lattice is substantially parallel to the x-axis direction, the stretching direction of the lattice is substantially orthogonal to the vertical direction, so that the stretching direction of the lattice is the y-axis. Compared with the case where the decorative panel 120 is attached so as to be substantially parallel to the direction, dust such as dust is more likely to adhere to the lattice. That is, the decorative panel 120 is easily soiled. As described above, in the above-described configuration example, the design property and the susceptibility to stain can be changed depending on the orientation of the decorative panel 120 in the xy plane. Therefore, as in the first embodiment, the orientation of the decorative panel 120 in the xy plane can be changed by 90 degrees, so that the user can change the orientation of the decorative panel 120 according to his / her preference, the environment of the living room, and the like. The orientation can be changed as appropriate, and a ventilation fan 10 that is more convenient for the user can be realized.

Hereinafter, other embodiments of the present invention will be described. In the following description of each embodiment, the description of the matters overlapping with the above-described first embodiment will be omitted, and the matters different from the first embodiment will be mainly described.
