Summary of the Invention
Problems to be Solved by the Invention
[0004] This type of piece of clothing with a blower is configured to attach a blower to a hole appropriately formed in the clothing body and send outside air into the clothing body through the blower. And as the blower, a blower having a plurality of blades (fan) rotated by driving a motor is generally used, and for safety, the periphery of the blower (and the motor) is surrounded by a guard having openings in a mesh shape, a net shape, or a lattice shape.
[0005] And since the piece of clothing with a blower supplies the air flow generated by the rotation of the blower into the clothing body through the guard, it is easy to store dust contained in the outside air in the guard. Therefore, after using the piece of clothing with a blower for a certain period of time, a maintenance operation for removing the dust in the guard of the blower is required.
[0006] In this regard, the blowers (blower for cooling inside clothing) disclosed in Patent Document 1 and Patent Document 2 disclose a coupling means that allows the impeller to be detachably attached to the motor.
[0007] In other words, by employing these coupling means, the impeller can be easily removed from the motor, and dust adhering to the back of the impeller blades can be easily removed.
[0008] However, depending on the working environment, oil and other substances may adhere to the motor part, and even with the means disclosed in Patent Document 1 and Patent Document 2, it may not be possible to thoroughly clean the motor part.
[0009] The present invention was developed in view of the above-mentioned technical problems, and aims to provide a novel blower that facilitates cleaning of the motor part, and a garment equipped with the blower. [Means for solving the problem]

[0016] Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to these embodiments.
[0017] <The present invention's blower (1)> Fig. 1 shows an embodiment of the blower 1 of the present invention. The blower 1 of the present invention includes a "motor unit (2)", an "impeller (3)", and a "guard (4)".
[0018] - Motor unit 2 - As shown in Fig. 2, the motor unit 2 drives the motor 21 by power supply through a cable (C) connected to the connector 22. The motor 21 is a mechanical element that outputs a rotational motion by utilizing the force generated by Lorentz force (interaction between magnetic field and current). In this embodiment, a commercially available brushless motor is used as the motor 21. As shown in Fig. 3, the motor 21 is held in a resin housing 23, and a cylindrical筒体24 is attached to the rotating shaft of the motor 21. On the peripheral wall of the housing 23, L-shaped connecting receiving portions 231 are provided at three locations with a 120-degree phase difference, and an operating portion 232 that can be pinched by fingers is provided at the end of the housing 23. On the other hand, the peripheral wall of the筒体24 also serves as the side wall portion of the motor 21, and when the motor 21 is driven, the peripheral wall of the筒体24 is configured to rotate around the motor 21.
[0019] - Impeller 3 - The impeller 3 rotates by the drive of the motor 21. As shown in Fig. 3, the impeller 3 includes 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 this embodiment, as the impeller 3, a seven-blade rotor having seven waraji-shaped blades 32 radially arranged around a hollow cylindrical boss 31 is used. Also, the impeller 3 is configured such that after fitting the boss 31 into the筒体of the motor unit 2, the connection state with the motor unit 2 is maintained by tightening the screw 6.
[0020] - Guard 4 - The guard 4 ensures safety during use of the blower 1 of the present invention by surrounding the motor unit 2 and the impeller 3. The guard 4 is divisible into a first guard 41 that surrounds the motor unit 2 and a second guard 42 that surrounds the impeller 3. As shown in Figure 1, in this embodiment, the guard 4 consists of two members: a dome-shaped first guard 41 and a second guard 42 that covers the opening of the first guard 41. By screwing the first guard 41 and the second guard 42 together, a space surrounding the motor unit 2 and the impeller 3 is formed. Furthermore, a cylindrical mounting hole 411 is provided in the center of the first guard 41, and three convex connecting claws 412 are provided on the inner circumferential wall of the mounting hole 411 with a phase difference of 120 degrees.
[0021] In constructing the blower 1 of the present invention having the above configuration, first, as shown in Figure 4, the motor unit 2 is inserted from the end side into the mounting hole 411 of the first guard 41 and rotated counterclockwise to engage the connecting claw 412 of the first guard 41 with the connecting receiving portion 231 of the motor unit 2. At this time, the end of the motor unit 2 is exposed from the first guard 41 through the mounting hole 411 and forms part of the first guard. An operating portion 232 is provided on the exposed portion (end) of the motor unit 2, and the rotation of the motor unit 2 can be performed by pinching the operating portion 232 with the fingers.
[0022] Next, as shown in Figure 5, the second guard 42 is screwed into the opening of the first guard 41, thereby constructing the blower 1 of the present invention, in which the motor unit 2 and the impeller 3 are surrounded by the guard 4.
[0023] Furthermore, in the blower 1 of the present invention, the motor unit 2 is detachably attached to the first guard 41, so if the motor parts such as the motor unit 2 or motor 21 become dirty, they can be easily removed and cleaned.
[0024] By the way, in this embodiment, a brushless motor is used for the motor 21, but the driving principle of the motor 21 is not limited in the present invention. Other examples of the motor 21 include brushed DC motors.
[0025] Furthermore, in this embodiment, when the motor unit 2 is attached to the first guard 41, a part of the motor unit 2 is exposed and forms part of the first guard 41. However, the motor unit 2 does not necessarily have to be structured to form part of the first guard 41. However, if a part of the motor unit 2 is exposed and forms part of the first guard 41, it is possible to provide an operating part 232 for attaching and detaching the motor unit 2, or a switch for controlling the rotation speed of the motor 21, as in this embodiment.
[0026] <Inventive clothing (10)> Figure 6 shows the garment 10 of the present invention equipped with the blower 1 of the present invention. The garment 10 of the present invention has the blower 1 of the present invention attached to the garment body (W). 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, the garment 10 of the present invention is constructed by making holes in multiple locations (two locations) of the garment body (W) and attaching the blower 1 of the present invention to each hole. The power to drive each blower 1 of the present invention is supplied by power stored in a battery (B) through a cable (C).
