Summary of the Invention

Problems to be Solved by the Invention

[0006] However, when attaching the blower to the garment itself, it is more common to place the palm of the hand over the entire surface of the air intake rather than placing fingers on the outer or back surface of the flange, and even if irregularities are formed on the outer or back surface of the flange, it cannot necessarily be said that attaching the blower becomes easier.

[0007] The present invention was developed in view of the aforementioned technical problems, and aims to provide a novel blower that is easier to attach to clothing, and clothing equipped with the blower. [Means for solving the problem]

[0015] Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to these embodiments.

[0016] [Embodiment 1] <Invention blower 1> FIG. 1 shows the blower 1 of the present invention according to Embodiment 1. The blower 1 of the present invention comprises a "motor (2)", an "impeller (3)" connected to the rotating shaft 21 of the motor 2, and a "housing (4)" surrounding the motor 2 and the impeller 3. Further, a "guard (5)" having a plurality of openings is arranged at the air inlet 41 provided in the housing 4.

[0017] -Motor 2- The motor 2 means a mechanical element that outputs rotational motion by utilizing the force generated by the Lorentz force (interaction between magnetic field and current). In the present embodiment, as the motor 2, a mechanism (a commercially available electric motor for models) that rotates the rotating shaft 21 by the electric power supplied through a cable connected to a connector is used.

[0018] -Impeller 3- The impeller 3 comprises a boss 31 and a plurality of blades 32 provided around the boss 31. The boss 31 is a member that forms the rotation center of the impeller 3, and the blades 32 rotate with the rotation of the boss 31 and play a role in generating an air flow in a certain direction. In the present embodiment, as the impeller 3, a seven-blade rotor comprising seven umbrella-shaped blades 32 radially arranged around the boss 31 is used. The connection between the impeller 3 and the motor 2 is made by exposing the rotating shaft 21 of the motor 2 from the end face of the boss 31 through a through hole 33 provided in the center of the boss 31 of the impeller 3 and screwing a screw (N) onto the rotating shaft 21.

[0019] -Housing 4- The outer shell 4 surrounds the motor 2 and the impeller 3, thereby ensuring safety during use of the blower 1 of the present invention. Furthermore, since the outer shell 4 needs to have a structure that allows the airflow generated by the rotation of the impeller 3 to pass through, it is equipped with an intake port 41 and an exhaust port 42. In this embodiment, the outer shell 4 consists of two components: a dome-shaped outer shell body 4A and a lid 4B that covers the opening of the outer shell body 4A. By screwing together a female screw portion 43 provided on the inner surface of the outer shell body 4A and a male screw portion 44 provided on the lid 4B, a space surrounding the motor 2 and the impeller 3 is formed. Furthermore, flanges (FA, FB) that protrude outward are provided around the opening of the outer shell body 4A and the air intake port 41 of the lid 4B, so that when the outer shell body 4A and the lid 4B are screwed together, the flanges (FA, FB) face each other.

[0020] -Guard 5- In the blower 1 of the present invention, a guard 5 having multiple openings formed by intersecting first fences 51 and second fences 52 is provided at the air intake port 41 on the outer shell 4. In this embodiment, the guard 5 is constructed by arranging multiple first fences 51 in parallel at regular intervals and arranging multiple second fences 52 perpendicular to the first fences 51.

[0021] Furthermore, as shown in Figure 2, the guard 5 has a step at the intersection of the first fence 51 and the second fence 52, and as a result, the second fence 52 protrudes outward from the outer shell 4 relative to the first fence 51. In this embodiment, the second fence 52 is made 1 mm higher than the first fence 51 toward the outer shell 4.

[0022] <Inventive clothing 10> As shown in Figure 3, the blower 1 of the present invention having the above configuration is attached to the garment body (W) to form the garment 10 of the present invention. The garment 10 of the present invention cools the inside of the garment body (W) by generating an airflow from the outside to the inside of the garment body (W) using the blower 1 of the present invention. In this embodiment, holes (H) are made in multiple locations (two locations) of the garment body (W), and the blower 1 of the present invention is attached to each hole (H). The power to drive each blower 1 of the present invention is supplied by power stored in a battery (C) through a cable.

[0023] As shown in Figure 4, in the blower 1 of the present invention according to this embodiment, the male screw portion 44 of the lid 4B is inserted into a hole (H) provided at an appropriate location on the garment body (W), and screwed into the female screw portion 43 of the outer shell body 4A inside the garment body (W), thereby sandwiching the periphery of the hole (H) between the flange (FA) of the outer shell body 4A and the flange (FB) of the lid 4B, and thus attaching it to the garment body (W).

[0024] During the attachment process to the garment body (W), it has been observed that, particularly when screwing the male threaded portion 44 and the female threaded portion 43 together, the palm of the hand is often placed over almost the entire surface of the air intake port 41, as shown in Figure 4.

[0025] Furthermore, in the blower 1 of the present invention, the second fence 52 protrudes outward from the outer shell relative to the first fence 51 at the guard 5 of the air intake port 41, so that the contours of the palm of the hand can easily catch on the second fence 52, making it less likely to slip, thus improving ease of attachment to the garment body (W).

[0026] In this embodiment, steps are provided at all intersection points of the first fence 51 and the second fence 52, causing all of the second fence 52 to protrude outward from the outer shell 4 relative to the first fence 51. However, in the present invention, steps may be provided at some of the intersection points of the first fence 51 and the second fence 52, causing some of the second fence 52 to protrude outward from the outer shell 4 relative to the first fence 51.

[0027] Furthermore, in this embodiment, the second fence 52 is set to be 1 mm higher than the first fence 51 toward the outside of the outer shell 4, but the protrusion height of the second fence 52 relative to the first fence 51 is not particularly limited. The protrusion height of the second fence 52 relative to the first fence 51 is preferably 0.1 to 5 mm (more preferably 0.2 to 2 mm).

[0028] [Embodiment 2] Figure 5 shows the blower 1 of the present invention according to Embodiment 2. The blower 1 of the present invention according to this embodiment also comprises a "motor (2)", an "impeller (3)" connected to the rotating shaft 21 of the motor 2, and an "outer shell (4)" surrounding the motor 2 and the impeller 3. The motor 2 and the impeller 3 are the same as those described in Embodiment 1. Furthermore, the outer shell body 4A of the outer shell 4 according to this embodiment is the same as the outer shell body 4A in Embodiment 1.

[0029] On the other hand, the lid 4B of the outer shell 4 according to this embodiment differs from the lid 4B in Embodiment 1 in that the pattern of the openings of the guard 5 covering the air intake port 41 is different.

[0030] -Guard 5- In this embodiment, when constructing the guard 5, the first fence 51 is arranged in an arc shape centered on the rotation axis 21 of the motor 2, while the second fence 52 is arranged to intersect the first fence 51, thereby creating the mesh pattern of the guard 5.

[0031] To describe the second fence 52 in more detail, it is arranged radially from the rotation shaft 21 of the motor 2 toward the periphery of the air intake port 41. Furthermore, the second fence 52 branches out along the way from the rotation shaft 21 of the motor 2 toward the periphery of the air intake port 41.

[0032] As shown in Figure 6, the guard 5 has a step at the intersection of the first fence 51 and the second fence 52, and as a result, the second fence 52 protrudes outward from the outer shell 4 relative to the first fence 51. In this embodiment, the second fence 52 is 1 mm higher than the first fence 51 toward the outer shell 4.

[0033] The blower 1 of the present invention, having the above configuration, is attached to the garment body (W) to form the garment 10 of the present invention (see Figure 3).

[0034] Furthermore, in the blower 1 of the present invention, the second fence 52 protrudes outward from the outer shell relative to the first fence 51 at the guard 5 of the air intake port 41, so that the contours of the palm of the hand can easily catch on the second fence 52, making it less likely to slip, thus improving ease of attachment to the garment body (W).

[0035] Furthermore, in configuring the guard 5 as in this embodiment, if the first fence 51 is arranged in an arc shape centered on the rotation axis 21 of the motor 2, the second fence 52, which is arranged to intersect with the first fence 51, extends in a direction intersecting the rotational direction in which the male screw portion 44 and the female screw portion 43 are screwed together. As a result, the contours of the palm of the hand are more likely to catch on the second fence 52, making it less likely to slip.

[0036] The rest is the same as in Embodiment 1, and to avoid repetition, the explanation is omitted here.

[0037] [Embodiment 3] Figure 7 shows the blower 1 of the present invention according to Embodiment 3. The blower 1 of the present invention according to this embodiment also comprises a "motor (2)", an "impeller (3)" connected to the rotating shaft 21 of the motor 2, and an "outer shell (4)" surrounding the motor 2 and the impeller 3. The motor 2 and the impeller 3 are the same as those described in Embodiment 1. Furthermore, the outer shell body 4A of the outer shell 4 according to this embodiment is the same as the outer shell body 4A in Embodiment 1.

[0038] On the other hand, the lid 4B of the outer shell 4 according to this embodiment differs from the lid 4B in Embodiment 1 in that the pattern of the openings of the guard 5 covering the air intake port 41 is different.

[0039] -Guard 5- In this embodiment, when constructing the guard 5, the first fence 51 is arranged in an arc shape centered on the rotation axis 21 of the motor 2, while the second fence 52 is arranged to intersect the first fence 51, thereby creating the mesh pattern of the guard 5.

[0040] To describe the second fence 52 in more detail, it is arranged radially from the rotation shaft 21 of the motor 2 toward the periphery of the air intake port 41. Furthermore, the second fence 52 branches out along the way from the rotation shaft 21 of the motor 2 toward the periphery of the air intake port 41.

[0041] Furthermore, the second fence 52 extends to the end face of the flange (FB).

[0042] In addition, the guard 5 has a step at the intersection of the first fence 51 and the second fence 52, so that the second fence 52 protrudes outward from the outer shell 4 relative to the first fence 51. In this embodiment, the second fence 52 is 1 mm higher than the first fence 51 toward the outer shell 4.

[0043] The blower 1 of the present invention, having the above configuration, is attached to the garment body (W) to form the garment 10 of the present invention (see Figure 3).

[0044] Furthermore, in the blower 1 of the present invention, the second fence 52 protrudes outward from the outer shell relative to the first fence 51 at the guard 5 of the air intake port 41, so that the contours of the palm of the hand can easily catch on the second fence 52, making it less likely to slip, thus improving ease of attachment to the garment body (W).

[0045] In particular, when constructing the guard 5 as in this embodiment, if the end of the second fence 52 is extended to the end face of the flange (FB), the point of force can be created at a position away from the rotational center where the male screw portion 44 and the female screw portion 43 are screwed together, further improving the ease of attachment to the garment body (W).

[0046] The rest is the same as in Embodiments 1 and 2 described above, and will be omitted here to avoid repetition.

[0047] Furthermore, the present invention can be implemented in various other forms without departing from its spirit or main features. Therefore, the embodiments described above are merely illustrative in all respects and should not be interpreted restrictively. The scope of the present invention is defined by the claims and is not restricted in any way by the text of the specification. Moreover, any modifications or changes falling within the equivalent scope of the claims are all within the scope of the present invention. [Industrial applicability]
