FIG. 4 is a partial cross-sectional view showing the mounting structure 130 in the state where the decorative panel 120 is mounted on the orifice 109 described later in the ventilation fan 10 according to Embodiment 1 of the present invention.

As shown in FIG. 1, ventilation fan 10 according to Embodiment 1 includes ventilation fan main body 101, electric motor 105, fan 107, shutter 108, decorative panel 120, and a member to which decorative panel 120 is attached. And a functioning orifice 109. The ventilation fan 10 is attached to a ventilation hole provided in a wall of a living room, and ventilates indoor air and outdoor air. In the following, when describing the configuration of the ventilation fan, 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, a direction from the outdoor side toward the indoor side is defined as a positive direction, and a reverse direction is defined as a negative direction. The two directions orthogonal to the z-axis direction are also referred to as the x-axis direction and the y-axis direction, respectively. In the state where the ventilation fan is attached to the wall, the up-down direction is the y-axis direction, and the left-right direction is the x-axis direction.

The ventilation fan main body 101 is a substantially rectangular tube-shaped member having openings (

main body openings

102a and 102b) 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 a strength for supporting 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 hole provided in the wall of the living room such that the

main body openings

102a and 102b face the indoor space and the outdoor space, respectively. A flange 103 is formed at the edge of the main body opening 102a on the indoor side of the ventilation fan main body 101 so as to protrude along the wall toward the outside of the main body opening 102a. In a partial area of the flange 103, a flange-side hooked portion 104 having a step-like shape is provided for hooking an orifice-side hooking portion 112 of an orifice 109 described later. In the illustrated example, the ventilation fan main body 101 has a substantially rectangular tube shape, but Embodiment 1 is not limited to such an example. For example, the ventilation fan main body 101 may have a substantially cylindrical shape.

(4) The electric motor 105 is provided inside the ventilation fan main body 101 such that the rotating shaft 106 is substantially parallel to the z-axis direction and protrudes toward the indoor side. Inside the ventilation fan main body 101, a motor fixing leg 115, which is a member for supporting the motor 105, extends in a substantially H shape. The electric motor 105 is fixed to a substantially H-shaped center 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 such that both ends thereof are connected to opposed inner walls of the ventilation fan main body 101, respectively. In addition, the shape of the motor fixed leg 115 is not limited to such an example. The electric motor fixing leg 115 may be any as long as it can fix the electric motor 105 at a desired position and posture in the ventilation fan main body 101, and may have any shape. For example, the motor fixed leg 115 may be substantially I-shaped or radial.

main body openings

102a and 102b of the ventilation fan main body 101, and ventilation is performed. Be done.

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

By providing the shutter 108, it is possible to prevent the invasion of outside air and rainwater by the wind. Note that the opening and closing method of the shutter 108 is not limited to the above-described wind pressure method, and may be, for example, a mechanical method. Further, the number of shutters 108 is not limited, and may be arbitrarily determined.

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

Four sides of the orifice body 110 are bent in a direction substantially perpendicular to the plate surface. As shown in FIG. 2, an orifice-side hook 112 protruding inward is provided at the bent portion of the orifice main body 110. The orifice main body 110 is disposed 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. As a result (specifically, the orifice side hooking portion 112 formed of a convex portion is hooked on the step of the flange side hooked portion 104), and 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 position 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 main body 101, the gap between the ventilation fan main body 101 and the fan 107 is closed by the plate surface of the orifice main body 110, and only the portion of the ventilation fan main body 101 facing the fan 107 has an orifice opening. It will be opened by the part 111. With such a configuration, the orifice opening 111 functions as a wind tunnel that allows air to efficiently flow through the fan 107. In the present specification, the indoor side of the orifice 109 may be referred to as a first side, and the side opposite to the first side may be referred to as a second side.

The configuration of the ventilation fan 10 described above may be the same as 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.

The 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 body 121 which is a plate-like member having a substantially square surface, and a panel-side mounting portion 151 for mounting the decorative panel 120 to the orifice 109. The structure of the panel-side mounting portion 151 will be described later in detail.

The panel main body 121 is provided with a stripe-shaped lattice extending in one direction on one surface (in the illustrated example, a stripe extending in the y-axis direction). Air circulates through the gaps in the grid to provide ventilation. The provision of the decorative panel 120 makes it difficult for the members (for example, the electric motor 105 and the fan 107) inside the ventilation fan main body 101 to be visually recognized from the indoor side through the orifice opening 111 and the main body opening 102a. Design can be improved.

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

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 (the second mounting portion of the present invention). ), And

The orifice-side mounting portions 141 are provided at positions corresponding to four corners of a surface of the orifice main body 110 which is substantially square and faces 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 is protruded from the surface on the first side of the orifice main body 110 toward the first side (that is, from the surface facing the decorative panel 120). A boss portion 142 provided so as to protrude toward the decorative panel 120) and a through hole 143 provided to penetrate the orifice 109 while penetrating the inside of the boss portion 142 in the protruding direction. The boss portion 142 has a substantially cylindrical shape having a substantially constant thickness from the root to the tip and having a substantially circular through hole 143 provided therein.

The orifice 109 can be formed by injection molding using a resin material. In this case, the orifice-side mounting portion 141 can be formed integrally with the orifice body 110 when forming the orifice 109. By integrally forming, the manufacturing cost can be reduced.

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

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

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

The pair of claws 153 are formed so as to protrude outward in the radial direction of the substantially cylindrical shape at the tip of the boss 152. A notch is provided at the tip of the boss 152, except for a portion where the pair of claws 153 are provided. The notches allow the pair of claw portions 153 to be elastically deformable so that the pair of claw portions 153 can move in a direction approaching each other in a radial direction of the substantially cylindrical shape of the boss portion 152.

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 formed integrally with the panel main body 121 when forming the decorative panel 120. By integrally forming, the manufacturing cost can be reduced.

When mounting the decorative panel 120 to the orifice 109, the boss 152 of the panel-side mounting portion 151 is inserted into the through hole 143 of the orifice-side mounting portion 141 from the first side. The outer diameter of the portion of the boss 152 where the pair of claws 153 is present 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 formed by the pair of claws 153. Can be elastically deformed so as to be able to move in a direction approaching each other, so that the pair of claws 153 slide on the inner wall of the through hole 143 while the elastic deformation is generated, and the boss 152 143.

The length of the boss portion 142 of the orifice-side mounting portion 141 and the length of the boss portion 152 of the panel-side mounting portion 151 are such that the boss portion 152 of the panel-side mounting portion 151 is fully inserted into the through hole 143 of the orifice-side mounting portion 141. Thus, the pair of claw portions 153 are adjusted so as to be exposed on the second side of the orifice 109. As shown in FIG. 4, when the pair of claw portions 153 are exposed to the second side of the orifice 109, the claw portions 153 return from the elastically deformed state to the original state, and are brought into contact with the plate surface of the orifice body 110 on the second side. Hang on. That is, the opening edge 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 claws 153 of the panel-side mounting portion 151 are hooked. The decorative panel 120 is attached to the orifice 109 by engaging the pair of claws 153 of the panel-side attaching portion 151 with the hooked portion of the orifice-side attaching portion 141 as described above.

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. The orifice 109 can be easily removed because the orifice 109 is simply attached to the flange-side hooked portion 104 of the flange 103 of the ventilation fan main body 101 by being hooked.

The 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 body 110 on the second side. The user grips the pair of claw portions 153 and elastically deforms the pair of claw portions 153 so as to approach each other in the radial direction of the boss portion 152, while attaching the boss portion 152 of the panel-side mounting portion 151 to the orifice-side mounting portion. The decorative panel 120 is moved with respect to the orifice 109 so as to be pulled out from 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 Embodiment 1, the mounting structure 130 for mounting the decorative panel 120 to the orifice 109 includes the panel-side mounting portion 151 (first mounting portion) provided on the decorative panel 120 and the orifice. And an orifice-side mounting portion 141 (second mounting portion) provided at the upper portion 109. The panel-side mounting portion 151 has a boss 152 (first boss) protruding toward the orifice 109 and a claw 153 provided on the boss 152. The orifice-side mounting portion 141 has a through hole 143 that allows the first side and the second side of the orifice 109 to communicate with each other. Then, when the decorative panel 120 is attached to the orifice 109, the boss 152 of the panel-side attaching portion 151 is inserted into the through hole 143 of the orifice-side attaching portion 141 from the first side, and the second , The claw portion 153 of the panel-side mounting portion 151 is exposed and locked. With the mounting structure 130, the user can mount the decorative panel 120 to the orifice 109 simply by inserting the boss 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 152 of the panel-side mounting portion 151 from the through hole 143 of the orifice-side mounting portion 141 while holding the pair of claws 153 from the second side of the orifice 109. Thus, the decorative panel 120 can be removed from the orifice 109.

As described above, according to the first embodiment, without using a tool, a decorative panel mounting structure in a conventional general ventilation fan (for example, a mounting structure using screws and a mounting structure in which a decorative panel is fitted). It is possible to easily attach and detach the decorative panel 120. Since the decorative panel 120 can be easily attached and detached, for example, the decorative panel 120 of various designs is prepared, and the user can change the panel appropriately according to the interior of the living room. The method becomes possible. Since the makeup panel 120 can be replaced according to the user's preference, the ventilation fan 10 with more excellent design can be realized. In addition, since it is possible to easily remove the decorative panel 120 from the orifice 109 and clean both of them easily, it is possible to maintain the portion of the ventilation fan 10 located on the indoor side and visible by the user in a clean state. it can. Therefore, the ventilation fan 10 with more excellent appearance can be realized.

In this specification, "the claw portion 153 is exposed on the second side of the orifice 109" means that the claw portion 153 is exposed from the second side to such an extent that the user can pick it by hand. Means In the first embodiment, the pawl portion 153 is hooked on the second side of the orifice 109 in a state of being exposed 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 are described. The mounting structures 130 are provided at positions corresponding to the four corners. Therefore, even when the decorative panel 120 is rotated by 90 degrees about the z-axis, the decorative panel 120 can be attached to the orifice 109 as in the original state. Accordingly, 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 or herself It is possible to appropriately select the orientation of the decorative panel 120 according to the user's preference and functionality.

For example, if the decorative panel 120 has a striped grid extending in one direction as in the above-described configuration example, the stretching direction of the grid changes by rotating the decorative panel 120 by 90 degrees around the z-axis. I can do it. For example, when the ventilation fan 10 is installed relatively high 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. In addition, since the user's line of sight is more likely to be blocked by the grid, the effect of making the internal members difficult to see is exhibited. That is, the design property can be further improved. On the other hand, when the decorative panel 120 is mounted such that the lattice extending direction is substantially parallel to the x-axis direction, the lattice extending direction is substantially orthogonal to the vertical direction, and thus the lattice extending direction is the y-axis. As compared with the case where the decorative panel 120 is attached so as to be substantially parallel to the direction, dust such as dust easily adheres to the grid. That is, the decorative panel 120 is easily stained. As described above, in the above-described configuration example, the design property and the easiness of soiling 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 direction can be changed appropriately, and the ventilation fan 10 more convenient for the user can be realized.

Hereinafter, another embodiment of the present invention will be described. In the following description of each embodiment, description of items that are the same as in the first embodiment will be omitted, and items that are different from the first embodiment will be mainly described.

It is possible to realize the same function as. Note that the shape of the boss 142b of the orifice-side mounting portion 141b is not limited to the above-described configuration example of the substantially rectangular tube shape, and may be another cylindrical shape such as a hexagon or an octagon.

Embodiment 4 FIG.
The configuration of the ventilation fan according to the fourth embodiment of the present invention will be described with reference to FIGS. FIG. 9 is a side view of an orifice 109c and a decorative panel 120c of a ventilation fan according to Embodiment 4 of the present invention. FIG. 10 is a longitudinal sectional view of the orifice 109c and the decorative panel 120c of the ventilation fan according to the fourth embodiment. As described above, in the first embodiment, the boss portion 142 of the orifice-side mounting portion 141 has a substantially constant thickness from the root to the tip. On the other hand, as shown in FIGS. 9 and 10, in the fourth embodiment, the boss portion 142c of the orifice-side mounting portion 141c has a step in the middle thereof, and has a shape in which the root side is thick and the tip side is thin. The through hole 143c provided therein also has a step portion 144c whose diameter changes in the middle so that the root side is large and the tip side is small, following the shape of the boss 142c.

In the fourth embodiment, the length of the boss 152c of the panel-side mounting portion 151c is shorter than the length of the boss 152 of the first embodiment. Then, as shown in FIG. 10, when the decorative panel 120c is attached to the orifice 109c, the claw portion 153c of the panel-side attaching portion 151c is not on the plate surface on the second side of the orifice body 110, but on the orifice side. The step portion 144c of the through hole 143c of the attachment portion 141c is hooked (that is, the step portion 144c functions as a hooked portion to which the claw 153c is hooked). In other words, when the decorative panel 120c is mounted on the orifice 109c, the panel 153c of the panel-side mounting portion 151c is hooked on the step 144c of the through hole 143c of the orifice-side mounting portion 141c. The length of the boss 152c of the side mounting portion 151c is adjusted. In order to ensure the ease of removing the decorative panel 120c, a portion of the through-hole 143c having a larger inner diameter at the base side has a larger inner diameter that allows at least a user's finger to be easily inserted, and a pair of claws 153c. It is configured so that it can be picked up. In other words, a portion where the inner diameter at the base side of the through hole 143c is larger is configured such that the pair of claw portions 153c can be exposed to the second side of the orifice 109c at the step portion 144c.

The configuration of the ventilation fan according to the fourth embodiment is the same as that of the first embodiment except that the shapes of the orifice-side mounting portion 141c of the orifice 109c and the panel-side mounting portion 151c of the decorative panel 120c in the mounting structure 130c are different. The description is omitted because it is the same as the ventilation fan 10.

Here, as in the first embodiment, the panel-side mounting portion 151c can be formed integrally with the panel main body 121 by injection molding using, for example, a resin material. In this case, if the length of the boss 152c of the panel-side mounting portion 151c is long, the surface of the panel body 121 opposite to the side where the boss 152c protrudes (that is, the surface facing the indoor space of the panel body 121). There is a possibility that a dent may occur on the surface to be rubbed (so-called sink marks may occur). The occurrence of such sink marks may impair the aesthetic appearance and may lead to a decrease in design. On the other hand, according to the fourth embodiment, the boss 142c and the through hole 143c of the orifice-side mounting portion 141c have a step, and the claw portion 153c of the panel-side mounting portion 151c is engaged with the step 144c. With such a structure, the length of the boss 152c of the panel-side mounting portion 151c can be reduced as compared with a case where such a step is not provided. Therefore, it is possible to suppress the occurrence of sink marks as described above and to provide a higher-quality ventilation fan.

In the configuration example described above, the boss portion 142c and the through hole 143c of the orifice-side attachment portion 141c both have a step in the middle, but the fourth embodiment is not limited to this example. If the step portion 144c exists in the through hole 143c, the step portion 144c functions as a hooked portion, and an effect similar to that of the above configuration example can be obtained. Therefore, for example, the boss portion 142c is not provided with a step portion (that is, the boss portion 142c has a substantially constant thickness), and the step portion 144c is provided only in the through hole 143c provided therein. May be.

Embodiment 5 FIG.
The configuration of the ventilation fan according to Embodiment 5 of the present invention will be described with reference to FIGS. FIG. 11 is a diagram showing a state where the orifice 109 and the decorative panel 120d in the ventilation fan according to Embodiment 5 of the present invention are viewed from the second side of the orifice 109. FIG. 12 is a diagram showing a structure of a panel-side mounting portion 151d of a ventilation fan according to Embodiment 5 of the present invention. In FIG. 12, one of the panel-side mounting portions 151d of the decorative panel 120d shown in FIG. 11 is extracted and shown.

As described above, in the first embodiment, the pair of claws 153 are provided for one boss 152 in the panel-side mounting portion 151. On the other hand, as shown in FIGS. 11 and 12, in the fifth embodiment, in the panel-side mounting portion 151d, one claw portion 153d is provided for one boss portion 152d. Note that the configuration of the ventilation fan according to the fifth embodiment is the same as that of the ventilation fan 10 according to the first embodiment except that the shape of the panel-side mounting portion 151d in the mounting structure 130d is different, and thus the description thereof is omitted. .

Even when one boss 152d is provided with one claw 153d as in the mounting structure 130d according to the fifth embodiment, the claw 153d is connected to the orifice body via the orifice-side mounting portion 141. The same function as the mounting structure 130 according to the first embodiment can be realized by being hooked on the second side surface of the portion 110.

Note that the panel-side mounting portions 151d are provided at positions corresponding to the four corners of the substantially square plate surface of the panel main body 121, respectively. The direction in which the claw portions 153d are provided in each panel-side mounting portion 151d is shown in FIG. It is preferable that each of the four panel-side attachment portions 151d is different as shown in FIG. For example, when the claw portions 153d of the four panel-side mounting portions 151d are all provided in the same direction (for example, the negative direction of the y-axis in FIG. 11), the direction in which the claw portions 153d are engaged. By moving the decorative panel 120d so as to be shifted in the opposite direction (for example, the positive direction of the y-axis in FIG. 11), all of the four claw portions 153d move in a direction in which the claw portions 153d are disengaged from the hooked portions. Thus, the decorative panel 120d is removed. That is, when all four claw portions 153d are provided in the same direction, the risk that the decorative panel 120d is unintentionally removed may increase. On the other hand, as in the fifth embodiment, for the four panel-side mounting portions 151d, the directions in which the claw portions 153d are provided are different from each other, so that the makeup is performed in a direction parallel to the xy plane or the like. Even when the panel 120d is about to be moved, any one of the four claw portions 153d is subjected to a force in the direction in which the claw portion 153d is engaged, so that the decorative panel 120d is removed. Never be. As described above, according to the fourth embodiment, it is possible to further reduce the risk of unintentionally removing decorative panel 120d, and to provide a more convenient ventilation fan for the user.
