In fig. 1 and 2 to 5, and also fig. 6 to 9 described later, some of the constituent members may be omitted.
Here, in fig. 2 to 9, the direction Z is an opening direction of the opening O of the frame 2, and the direction X and the direction Y are directions orthogonal to each other and to the direction Z.
(overview of the air door device 1)
As shown in fig. 2 to 6, the damper device 1 of the present embodiment includes a frame 2 having a rectangular opening O formed therein, a shutter 3 for opening and closing the opening O of the frame 2, and a drive portion 10 of the shutter 3 adjacent to the opening O and the shutter 3 in the X direction with a partition plate 2a interposed therebetween. The partition plate 2a and the driving portion 10 are coupled by a coupling portion 11. The frame 2, the partition plate 2a, and the case 12 as an outer wall portion of the drive section 10 are made of resin. A motor, a gear train, and the like for driving (rotating) the baffle 3 are formed inside the housing 12.
The frame 2 includes a rectangular end plate portion 2b having an opening O formed therein, and a square tubular body portion 2c protruding from an outer edge of the end plate portion 2b in the Z direction. The end plate 2b is formed with a square tubular sealing plate 2e, and the sealing plate 2e protrudes from the edge of the opening O toward the side (along the Z direction) where the baffle 3 is located.
The baffle 3 has an annular elastic body 4, and the opening O is closed (the state shown in fig. 3 to 5) by abutting the elastic body 4 against the seal plate portion 2 e. As shown in fig. 4 and 5, the baffle 3 is provided with a groove portion 3a for holding the elastic body 4. The groove portion 3a is formed at a position facing the front end portion 2d of the seal plate portion 2e in a state where the shutter 3 is positioned at the closed position. Therefore, as shown in fig. 4 and 5, the elastic body 4 attached to the groove portion 3a and the distal end portion 2d of the seal plate portion 2e face each other in a state where the shutter 3 is positioned at the closed position. The elastic body 4 is pressed against the distal end portion 2d and elastically deformed, whereby the opening O is sealed. In fig. 4 and 5, in order to clearly show the original shape of the elastic body 4, the elastic body 4 is shown in a state in which a part thereof overlaps the distal end portion 2d and is not elastically deformed, but actually, in a state in which the shutter 3 is positioned at the closed position, the elastic body 4 is pressed against the distal end portion 2d and is elastically deformed as described above.
The shutter 3 is supported by the frame 2 and is rotatable about a rotation center axis L extending in the X direction (see fig. 2 and 3), and the driving unit 10 rotates the shutter 3 about the rotation center axis L to open and close the opening O.
As described above, the damper device 1 of the present embodiment is applicable to the refrigerator 101 and the like, and is disposed inside the duct constituting the cold air passage. Here, the cold air may flow through the opening O from the side where the damper 3 is disposed with respect to the opening O (for example, the disposition of the damper device 109 in the refrigerator 101 of fig. 1). Alternatively, the air may flow through the opening O from the side opposite to the side where the shutter 3 is disposed with respect to the opening O (for example, the disposition of the damper device 108 in the refrigerator 101 of fig. 1).
As described above, the damper device 1 of the present embodiment includes: a frame 2 having an opening O; a shutter 3 for opening and closing the opening O; a driving section 10 for the shutter 3; and an annular elastic body 4 provided on at least one of the frame 2 and the shutter 3, and having an abutting portion 40, the abutting portion 40 abutting against the seal plate portion 2e as the peripheral edge portion of the opening O when the shutter 3 is driven to the closed position by the driving portion 10.
That is, in the damper device 1 of the present embodiment, the annular elastic body 4 facilitates uniform arrangement of the sealing member on the peripheral edge of the opening O. Further, by adopting such a structure, the sealing property when the shutter 3 is positioned at the closed position can be improved.
The elastic body 4 may be disposed on the peripheral edge of the opening O as long as the elastic body 4 is disposed on the peripheral edge, and includes any of the case where the elastic body 4 is formed on the baffle 3, the case where the elastic body 4 is formed on the frame 2, and the case where the elastic body 4 is formed on both the baffle 3 and the frame 2 as in the present embodiment.
Here, as shown in fig. 5, in the damper device 1 of the present embodiment, the elastic body 4 has a curved portion 41 in cross section, and the contact portion 40 is the curved portion 41. Therefore, in the damper device 1 of the present embodiment, the elastic body 4 can be simply formed. However, the elastic body 4 is not limited to this structure. For example, the elastomer 4 may be formed by disposing a fluid composition containing silicone rubber or the like at the peripheral edge of the opening O, and volatilizing the volatile component of the fluid composition to form an elastomer or the like.
As described above, the damper device 1 of the present embodiment includes the groove portion 3a for holding the elastic body 4. Therefore, in the damper device 1 of the present embodiment, the elastic body 4 is held with a simple structure. However, the structure of the holding elastic body 4 is not limited to the groove portion of the structure like this embodiment.
In the present embodiment, the width of the groove portion 3a is formed smaller than the diameter of the elastic body 4, and the elastic body 4 is pressed into the groove portion 3a, whereby the groove portion 3a is configured to hold the elastic body 4. However, for example, in order to make the elastic body 4 less likely to fall off the groove portion 3a, an barb (projection) may be formed in the groove portion 3a, or a structure for holding the elastic body 4 by a structure other than the groove portion (for example, bonding using an adhesive or the like) may be adopted.
As shown in fig. 2, the opening O of the damper device 1 of the present embodiment is rectangular. Therefore, the opening O can be formed simply, providing a more efficient (wide) opening O for the end plate portion 2b of the rectangular frame 2. However, the shape of the opening O is not particularly limited, and may be set to various shapes according to the shape of the frame 2 and the like.
(damper device 1 of embodiment 2)
The elastic body 4 of the damper device 1 of example 1 is formed on the baffle 3.
Next, the damper device 1 of example 2 in which the elastic body 4 is formed on the frame 2 will be described.
Fig. 6 is a schematic side view showing the damper device 1 according to example 2, and is a sectional view corresponding to fig. 5.
The constituent members common to those of embodiment 1 are denoted by the same reference numerals, and detailed description thereof is omitted.
Here, the damper device 1 of the present embodiment has the same configuration as the damper device 1 of embodiment 1, except for the configurations of the frame 2 and the damper 3.
As shown in fig. 6, in the frame 2 of the damper device 1 of the present embodiment, a groove portion 2g is formed in the seal plate portion 2f which is the peripheral edge portion of the opening portion 0. The annular elastic body 4 is held by the groove portion 2 g.
As described above, in the damper device 1 of embodiment 1, the elastic body 4 is formed on the baffle 3. In the damper device 1 of the present embodiment, the elastic body 4 is formed on the frame 2. However, for example, the damper 3 of the damper device 1 according to embodiment 1 and the frame 2 of the damper device 1 according to embodiment may be combined to form the elastic body 4 on both the damper 3 and the frame 2 (for example, a structure in which the elastic bodies are brought into contact with each other when the damper 3 is positioned at the closed position).
(damper device 1 of embodiment 3)
In the damper device 1 of examples 1 and 2, the elastic body 4 has a circular cross section and a shape in which the constituent material is filled therein.
Next, the damper device 1 in which the shape of the elastic body 4 is different from that of the embodiments 1 and 2 will be described.
Fig. 7 is a schematic side view showing the damper device 1 according to example 3, and is a sectional view corresponding to fig. 5.
The constituent members common to those in embodiments 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted.
Here, the damper device 1 of the present embodiment has the same configuration as the damper device 1 of embodiment 1, except for the shape of the elastic body 4.
As shown in fig. 7, the elastic body 4 of the damper device 1 of the present embodiment has a circular cross section, and the elastic body 4 has a hollow portion 4a inside. That is, the cross section is hollow. Since the hollow portion 4a is formed, the elastic body 4 of the present embodiment is easily deformed (easily crushed). Therefore, the damper device 1 of the present embodiment has the structure: when the shutter 3 is positioned at the closed position, the elastic body 4 is effectively deformed and the opening O can be sealed as the elastic body 4 comes into contact with the tip end portion 2d of the seal plate portion 2e, which is a contact portion with the elastic body 4.
(damper device 1 of embodiment 4)
In the damper device 1 of examples 1 and 2, the elastic body 4 has a circular cross section and a shape in which the constituent material is filled therein. In example 3, the elastic body 4 has a circular cross section and a hollow cross section having a hollow portion 4a inside.
Next, the damper device 1 in which the shape of the elastic body 4 is different from that of the embodiments 1 to 3 will be described.
Fig. 8 is a schematic side view showing the damper device 1 according to example 4, and is a sectional view corresponding to fig. 5.
The constituent members common to those in embodiments 1 to 3 are denoted by the same reference numerals, and detailed description thereof is omitted.
Here, the damper device 1 of the present embodiment has the same configuration as the damper device 1 of embodiment 1, except for the shape of the elastic body 4.
As shown in fig. 8, the elastic body 4 of the damper device 1 of the present embodiment has a circular cross section and has a shape having a slit 4b, and the slit 4b is formed in one turn along the peripheral edge portion. The elastic body 4 of the present embodiment is easily deformed (easily crushed) due to the formation of the slit 4 b. Therefore, the damper device 1 of the present embodiment has the structure: when the shutter 3 is positioned at the closed position, the elastic body 4 is effectively deformed as the elastic body 4 comes into contact with the tip end portion 2d of the seal plate portion 2e, which is a contact portion with the elastic body 4, and the sealing property of the opening O can be improved.
(damper device 1 of embodiment 5)
In the damper devices 1 of examples 1, 3, and 4, the thickness of the seal plate portion 2e does not change (the thickness is constant in the Z direction) as it advances toward the leading end portion 2 d.
Next, a damper device 1 in which the shape of the seal plate portion is different from those of embodiments 1, 3, and 4 will be described.
Fig. 9 is a schematic side view showing the damper device 1 according to example 5, and is a sectional view corresponding to fig. 5.
The constituent members common to those in embodiments 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.
Here, the damper device 1 of the present embodiment has the same structure as the damper device 1 of embodiment 1 except for the shape of the seal plate portion.
As shown in fig. 9, the seal plate portion 2h (peripheral edge portion) of the present embodiment has a tapered shape, and the thickness thereof gradually decreases as it advances toward the distal end portion 2 i. In other words, in the damper device 1 of the present embodiment, when the flapper 3 is driven to the closed position by the drive portion 10, the contact portion (the distal end portion 2i of the seal plate portion 2 h) with the elastic body 4 is gradually thinned as it advances to the side in contact with the elastic body 4. Therefore, as the shutter 3 is moved from the contact start position of the contact portion and the elastic body 4 to the closed position, the damper device 1 of the present embodiment starts to contact the elastic body 4 with a small contact area while deforming the elastic body 4. Therefore, the damper device 1 of the present embodiment has the structure: the elastic body 4 can be effectively deformed and the opening O can be sealed.
(damper device 1 of embodiment 6)
Next, a description will be given of the damper device 1 in which the shape of the seal plate portion is different from that of embodiments 1 to 5.
Fig. 10 is a schematic side view showing the damper device 1 according to example 6, and is a sectional view corresponding to fig. 5.
The constituent members common to those in embodiments 1 to 5 are denoted by the same reference numerals, and detailed description thereof is omitted.
Here, the damper device 1 of the present embodiment has the same structure as the damper device 1 of embodiment 1 except for the shape of the seal plate portion.
As shown in fig. 10, the seal plate portion 2j (peripheral portion, contact portion) of the present embodiment is a slope having a width of the distal end portion 2k larger than the diameter of the elastic body 4. Therefore, even if the position of the shutter 3 is slightly deviated with respect to the frame 2 when the shutter 3 is driven from the open position to the closed position, the elastic body 4 and the leading end portion 2k can be effectively brought into contact. Therefore, the damper device 1 of the present embodiment has the following structure: it is possible to suppress the deterioration of the sealing performance of the opening O due to the positional deviation of the shutter 3 with respect to the frame 2.
The present invention is not limited to the above-described embodiments, and can be realized in various configurations without departing from the scope of the invention. For example, in order to solve part or all of the above-described technical problems or to achieve part or all of the above-described effects, technical features in embodiments corresponding to technical features in the aspects described in the section of the present application may be appropriately replaced or combined.
In addition, if technical features are not described as essential features in the present specification, they may be deleted as appropriate.
As a configuration other than the above embodiment, for example, the heater may be disposed in the peripheral portion of the peripheral edge portion of the opening O in the frame 2. When the damper device 1 is disposed in a low-temperature environment, ice may form between the frame 2 and the damper 3, and the damper 3 may be difficult to open and close with respect to the frame 2. However, by disposing the heater in the peripheral portion of the opening O in the frame 2, for example, even if the damper device 1 is disposed in a low-temperature environment, the shutter 3 can be prevented from being opened and closed with respect to the frame 2 with difficulty by heating with the heater. Further, even when the baffle 3 is in the closed position and ice is formed between the frame 2 and the baffle 3, it is possible to suppress the elastic body from falling off as the baffle 3 enters the open position.
