《Action ・ Effect》
Next, the operation and effect of the present embodiment having the above-described configuration will be described.

According to the present embodiment, as shown in FIG. 1, the cover portion 10 that covers the suction port 21 is provided so as to face the suction port 21, and the gap G is formed between the housing 20 and the cover portion 10. The outside air is taken into the housing 20 from the suction port 21 through the gap G. For this reason, even if the front of the blower faces the user's body, the outside air is taken in from the suction port 21 to the outside of the housing 20 without reducing the efficiency. ) Can be sent out.

In this regard, in a conventional blower such as the blower disclosed in US Pat. No. 7,828,524, when the front of the blower faces the user's body, a suction port provided on the front of the housing The outside air could not be sucked in and the function as a blower could not be performed. Especially when the user has many opportunities to move the body, the front of the blower often faces the body, and there are even complaints from the user.

On the other hand, according to the present embodiment, since the cover portion 10 having the above-described configuration is provided, even if the front of the blower faces the user's body, the efficiency is reduced. The outside air can be taken in from the suction port 21 and can function as a blower. For this reason, the blower according to the present embodiment can provide a very beneficial effect as compared to the blower disclosed in US Pat. No. 7,828,524 in that it always functions as a blower.

In addition, according to the present embodiment, since the cover portion 10 that covers the suction port 21 is provided facing the suction port 21, it is difficult for foreign matter, fingers, and the like to enter the housing 20. In particular, in the present embodiment, since the entire surface of the suction port 21 is covered with the cover portion 10, a finger does not enter the housing 20, and it is reliably prevented that the finger touches the blade 31. be able to.

Furthermore, according to the present embodiment, since the entire surface of the suction port 21 is covered with the cover portion 10, the suction port 21 is completely hidden, and the design can be improved, and in turn, the customer's willingness to purchase is increased. be able to.

As shown in FIGS. 4 to 6, in the present embodiment, the upper end of the cover portion 10 is connected to the housing 20, and a gap G is formed between the both side ends of the cover portion 10 and the housing 20. (Refer FIG.4 and FIG.5) and it consists of the structure formed between the lower part of the cover part 10 and the housing | casing 20 (refer FIG. 6). For this reason, outside air can be taken into the housing 20 not from above the suction port 21 but from below and from the side of the suction port 21. In the aspect which takes in external air from the upper direction of the suction port 21, since the external air taken in in the housing | casing 20 from upper direction will be sent out upward from the ventilation port 22, the flow of external air will be disturbed. For this reason, a wind cannot be sent efficiently to a user, and a comfortable wind cannot be sent. On the other hand, in the present embodiment, the outside air can be taken into the housing 20 from the lower side and the side of the suction port 21 and sent out upward from the blower port 22, and the flow of the outside air is not disturbed. For this reason, a comfortable wind can be efficiently sent to a user. Even if only a part of the upper end of the cover 10 is connected to the housing 20, the flow of outside air can be prevented to some extent, and a relatively comfortable wind can be efficiently sent to the user. .

As shown in FIGS. 4 and 5, in the present embodiment, a pair of lower support portions 41 are provided between both side end portions of the lower portion of the cover portion 10 and the housing 20. For this reason, it can prevent that the lower end of the cover part 10 bends below, and can prevent blocking the flow of the external air taken in in the housing | casing 20 from the downward direction of the suction opening 21 by extension.

Further, as shown in FIG. 6, in the present embodiment, since the lower auxiliary support portion 42 is provided between the pair of lower support portions 41, the lower end of the cover portion 10 is bent toward the housing 20. Therefore, it is possible to more reliably prevent the flow of outside air taken into the housing 20 from below the suction port 21 from being blocked.

As shown in FIGS. 4 and 5, in the present embodiment, a pair of upper support portions 46 are provided between both side end portions of the upper portion of the cover portion 10 and the housing 20. For this reason, it can prevent that the upper part of the cover part 10 bends toward the housing | casing 20, and also prevents that the flow of the external air taken in in the housing | casing 20 from the side of the suction port 21 is interrupted | blocked. can do.

Further, as shown in FIGS. 4 and 5, in the present embodiment, a pair of side auxiliary support portions 47 are provided between the both side ends of the center portion of the cover portion 10 and the housing 20. For this reason, it can prevent more reliably that the both sides of the cover part 10 bend toward the housing | casing 20, and also interrupt | block the flow of the external air taken in in the housing | casing 20 from the side of the suction port 21 by extension. It can prevent more reliably.

Further, as shown in FIG. 3, in the present embodiment, the downstream end portion 35 e of the guide wall 35 extends linearly to the blower port 22 in the vertical direction. An opening 39 is provided above the left side of the rotating body 30, and a guide wall 35 is provided above the right side of the rotating body 30. Further, the width Wa of the outside air passage 36 formed between the guide wall 35 located on the left side when viewed from the front side and the rotating body 30 is set to be the outside air formed between the guide wall 35 located on the right side and the rotating body 30. It is larger than the width Wb of the passage 36. From these things, according to this Embodiment, the external air taken in in the housing | casing 20 from the suction port 21 can be sent out from the ventilation port 22 to the upper direction of the housing | casing 20 straight.

In this regard, in a conventional blower such as the blower disclosed in US Pat. No. 7,828,524, the outside air taken into the housing from the suction port is sent out obliquely above the housing from the blower port. Thus, there are some users who feel uncomfortable with the outside air being sent out obliquely, and there has been a demand for sending outside air straight above the housing. In this regard, according to the present embodiment, (1) the downstream end 35e of the inner wall extends in a straight line up to the blower port 22 and (2) the opening 39 is provided above the left side of the rotating body 30. In addition, a guide wall 35 is provided above the right side of the rotating body 30. (3) Furthermore, an outside air passage 36 formed between the guiding wall 35 located on the left side when viewed from the front side and the rotating body 30. The width Wa is taken into the housing 20 from the suction port 21 by a configuration in which the width Wa is larger than the width Wb of the outside air passage 36 formed between the guide wall 35 located on the right side and the rotating body 30. Outside air can be sent straight out from the blower opening 22 to the housing 20. For this reason, the blower according to the present embodiment can provide a very beneficial effect compared to the blower disclosed in US Pat. No. 7,828,524 in that the blower can be used without a sense of incongruity.

Note that (1) the downstream end 35e of the inner wall extends linearly up and down to the air blowing port 22, and (2) the opening 39 is provided above the left side of the rotating body 30 and rotates. A guide wall 35 is provided above the right side of the body 30, and (3) the width Wa of the outside air passage 36 formed between the guide wall 35 located on the left side when viewed from the front side and the rotating body 30. The outside air (wind) is directly above the housing 20 from the blower opening 22 due to each being larger than the width Wb of the outside air passage 36 formed between the guide wall 35 located on the right side and the rotating body 30. As a result, it is possible to obtain a corresponding effect. For this reason, it should be pointed out that it is not always necessary to combine all of (1) to (3). In other words, with respect to the point that the outside air (wind) is sent out directly from the blower opening 22 to the housing 20, a certain degree of effect can be obtained with each of the above (1), (2), and (3). A relatively high effect can be obtained by combining any two of (1), (2) and (3) described above.

By the way, in the present embodiment, since the cover portion 10 covering the suction port 21 is provided, the amount of outside air taken into the housing 20 is inevitably reduced, and the amount of wind sent out from the blower port 22 is small. turn into. In this regard, according to the present embodiment, as described above, the air can be sent straight up from the air outlet 22 to the housing 20, and the distance from the air outlet 22 to the user's face, for example, can be shortened. . For this reason, even if the quantity of the external air sent out from the ventilation port 22 decreases, it can be supplemented. Thus, sending out the outside air (wind) from the blower port 22 directly above the housing 20 can solve a new problem caused by the provision of the cover 10 that covers the suction port 21. It is very useful.

By the way, when the gap G between the housing 20 and the cover portion 10 becomes small, noise is generated in the gap G. If the gap G becomes too small, for example, 1.0 mm, the outside air cannot be taken in from the suction port 21 and the air sent from the blower port 22 is reduced (see “Table 1” below). ).

Considering the results shown in Table 1, if the gap G is 2.0 mm, a large amount of noise is generated, but an appropriate amount of wind flows from the blower opening 22, so that the gap G can be set to 2.0 mm. . Further, if the gap G is 2.5 mm, the noise level is preferably moderate, and if the gap G is 3.0 mm, the noise is reduced, which is very preferable. That is, the gap G is preferably 2.0 or more, more preferably 2.5 mm or more, and further preferably 3.0 mm or more.

By the way, as described above, when the gap G is 1.0 mm, an appropriate amount of wind cannot be sent from the air outlet 22, whereas when the gap G is 2.0 mm, an appropriate amount of air is sent from the air outlet 22. Can send. For this reason, it can be said that there is a significant difference between inside and outside the numerical limitation that the gap G is 2.0 mm or more, and that the gap G is 2.0 mm or more has a critical significance.

On the other hand, if the gap G between the housing 20 and the cover part 10 becomes too large, the thickness of the blower becomes large, which is inconvenient to carry and also looks bad. In this respect, since the thickness of the casing 20 of the blower according to the present embodiment is approximately 16 mm, it is not preferable that the gap G is larger than 4.0 mm corresponding to ¼ thereof. It is preferably 0 mm or less. In order to improve the appearance, the gap G is more preferably 3.5 mm or less, and even more preferably 3.3 mm or less.

As shown in FIG. 9, in this embodiment, the string portion 60 is partly separable (in the vicinity of the end portion in this embodiment), and as shown in FIGS. A string attaching portion 70 for attaching the string portion 60 is provided on both side surfaces. For this reason, the string part 60 can be attached to the both sides | surfaces of the housing | casing 20, and a blower can be hung straight down from a user's neck, for example. And as above-mentioned, in the air blower of this Embodiment, since the external air taken in in the housing | casing 20 from the suction port 21 can be sent out straightly upward of the housing | casing 20 from the air blowing port 22, for example, a user's face The wind can be sent from below.

In this regard, in a conventional blower such as the blower disclosed in US Pat. No. 7,828,524, the string portion is not separable in part, so the string portion is attached only to one side of the housing. I couldn't. For this reason, when the blower is hung on the user's neck, for example, the blower inevitably tilts obliquely. On the other hand, according to the present embodiment, the string portion 60 is partly separable in the vicinity (in the vicinity of the end portion in the present embodiment), and therefore the strings provided on both side surfaces of the upper portion of the housing 20. The string portion 60 can be attached to the attachment portion 70. As a result, as described above, in the blower according to the present embodiment that can be sent straight out from the blower opening 22 to the housing 20, it is possible to obtain an effect that the wind can be sent from, for example, directly under the face of the user. it can.

As described above, the fact that the blower 22 can be sent straight up above the housing 20 and that the blower can be hung straight down from the user's neck, for example, have a synergistic effect. I will point out a certain point.

Further, in the present embodiment, the string portion 60 is provided with an adjusting portion 65 for adjusting the length thereof, and the length of the string portion 60 is adjustable. For this reason, according to this Embodiment, according to a user's liking and a use, the length of a string can be changed suitably.

Further, in the present embodiment, the clip portion 50 is provided on the back surface of the housing 20. For this reason, attaching a blower to clothes, such as a shirt, can prevent a blower from hanging.

In addition, the clip part 50 of this Embodiment selects whether it opens toward the up-down-left-right direction seeing from the back side of the housing | casing 20 by rotating with respect to the back surface of the housing | casing 20. It can be attached.

For this reason, for example, when a male user uses the blower of the present embodiment, the clip unit 50 is rotated and positioned so as to open toward the left as viewed from the back side of the housing 20, and the shirt A blower can be attached to clothes, such as (refer FIG. 7 (a) and FIG. 10 (a)). On the other hand, for example, when a female user uses the blower of the present embodiment, the clip unit 50 is rotated and positioned so as to open in the right direction when viewed from the back side of the housing 20, and a shirt or the like. A blower can be attached to the clothes (see FIGS. 7B and 10B).

Also, by positioning the clip portion 50 so as to open downward as viewed from the back side of the housing 20, for example, a blower can be attached to the chest pocket of the shirt or the waist of the pants. Further, the clip portion 50 is rotated and positioned so as to open upward when viewed from the back side of the housing 20, and for example, the air outlet 22 may be attached to the neck portion of the T-shirt so as to face downward. it can.

In the present embodiment, as shown in FIG. 10, the extending portion 52 of the fixing portion 53 is positioned in the notch 57 of the stand portion 56, but FIGS. As shown in FIG. 5, a convex portion 90 is provided above the stand portion 56. The convex portion 90 prevents the clip portion 50 from coming out of the notch 57 even when the clip portion 50 moves upward in the notch 57. For this reason, after positioning the clip part 50 so as to open upward as viewed from the back side of the housing 20, for example, even if the blower port 22 is attached to the neck part of the T-shirt so that it faces downward, The clip part 50 does not come out from the notch 57.

Lastly, the description of the embodiment and the disclosure of the drawings described above are merely examples for explaining the invention described in the claims, and the claims are made based on the description of the embodiment or the disclosure of the drawings. It should be pointed out that the invention described in the scope of is not limited.
