Description

[Technical field]

[0001] The present invention relates to an internal clothing cooling fan that is attached to a clothing body and sends outside air into the clothing body, and to clothing with a fan that includes the internal clothing cooling fan. [Background technology]

[0002] Recently, clothing with a blower (cooling clothing) that cools the inside of clothing such as work clothes (hereinafter referred to as the "garment body") by supplying outside air into the clothing body has been put into practical use (see, for example, Patent Document 1 below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-214948 A Summary of the Invention [Problem to be solved by the invention]

[0004] This type of clothing with a fan is designed so that a fan is attached to a hole opened at an appropriate position in the body of the clothing, and outside air is sent into the body of the clothing through the fan. As shown in Fig. 6, the fan 100 generally rotates an impeller 3 (fan) having multiple blades by a motor 2, and power for driving the motor 2 is supplied from a portable battery via a cable (C).

[0005] In addition, in order to ensure safety in handling, the blower 100 is structured such that the periphery of the impeller 3 is surrounded by a guard 4. As shown in Fig. 7, when the blower 100 is attached to a garment body (W), most of the volume of the blower 100 protrudes toward the inside of the garment body (W), resulting in a rough feel when used.

[0006] Here, it would seem that the bulkiness of the fan 100 could be easily eliminated by simply downsizing the motor 2 and designing the guard 4 so that its thickness (thickness (T) in the direction along the rotation shaft of the motor) is thin. However, since it is necessary to provide the connector box 5 equipped with the connector 51 for connecting the terminal (C1) of the cable (C) in the guard 4, it was practically impossible to design the thickness of the guard 4 to 45 mm or less.

[0007] The present invention has been developed in consideration of the above-mentioned technical problems, and aims to provide a new internal clothing cooling fan that eliminates bulkiness, and a garment equipped with such an internal clothing cooling fan. [Means for solving the problem]

[0008] The in-garment cooling fan of the present invention, which solves the above-mentioned technical problems, is an in-garment cooling fan that is attached to a garment body and sends outside air into the garment body, and is characterized in that it comprises a motor that rotates with power supplied from a battery, an impeller that rotates with the driving force of the motor, and a guard that surrounds the impeller, and the thickness of the guard is 40 mm or less (hereinafter referred to as the "fan of the present invention").

[0009] In the blower of the present invention, in a preferred embodiment, a connector box having a connector for connecting the terminals of the battery is provided on the peripheral wall of the guard.

[0010] In the fan of the present invention, it is preferable that the connector provided in the connector box is arranged parallel to the rotation shaft of the motor.

[0011] The garment with a blower of the present invention, which solves the above technical problems, is characterized in that the blower of the present invention is attached to the garment body (hereinafter referred to as "garment of the present invention"). Effect of the Invention

[0012] The blower of the present invention eliminates bulkiness, improving the comfort of the garment of the present invention to which the blower of the present invention is attached. [Brief description of the drawings]

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.

[0015] <Blower 1 of the present invention> Fig. 1 shows one embodiment of a blower 1 of the present invention. The blower 1 of the present invention includes a "motor (2)", an "impeller (3)" that rotates by the driving force of the motor 2, and a "guard (4)" that surrounds the periphery of the impeller 3.

[0016] -Motor 2- The motor 2 refers to a mechanical element that outputs rotational motion by utilizing a force generated by the Lorentz force (the interaction between a magnetic field and an electric current). In this embodiment, a commercially available electric motor for models that is driven by supplied electric power is used as the motor 2.

[0017] - Impeller 3 - The impeller 3 is a mechanical element for generating a flow of air in a fixed direction by rotating under the driving force of the motor 2 (the rotational motion output from the motor 2). As shown in Fig. 3, in this embodiment, a seven-blade rotor including a boss 31 that forms the rotation center of the impeller 3 and five eboshi-shaped blades 32 that are radially arranged around the boss 31 is used as the impeller 3.

[0018] -Guard 4- The guard 4 ensures the safety of the blower 1 of the present invention during use by surrounding the impeller 3. The guard 4 must be structured to allow the air flow generated by the rotation of the impeller 3 to pass through, and therefore has mesh-like, net-like, or lattice-like openings at least in the portion facing the front and back surfaces of the blades 32 of the impeller 3. In this embodiment, the guard 4 is made of two members: a guard body 41 having a cylindrical peripheral wall 411 and a dome-shaped ceiling 412, and a guard lid 42 covering the opening of the guard body 41. A female screw provided on the inner surface of the peripheral wall 411 of the guard body 41 and a male screw provided on the outer peripheral wall of the guard lid 42 are screwed together to form a space surrounding the motor 2 and the impeller 3. The motor 2 is fixed to the center of the guard body 41.

[0019] 2, the fan 1 of the present invention is adapted to receive power from a battery (B) via a cable (C). Therefore, the fan 1 of the present invention further includes a "connector box (5)" having a connector 51 for connecting a terminal (C1) of the cable (C).

[0020] - Connector box 5 - In the present invention, the connector box 5 is provided on the peripheral wall 411 of the guard 4. In this embodiment, the connector 51 provided on the connector box 5 is arranged to be parallel to the rotating shaft 21 of the motor 2. As shown in Fig. 3, the connector 51 and the motor 2 are connected via a wiring (L), and in this embodiment, the wiring (L) is arranged in a state of being housed in a hollow wiring box 43 arranged along the ceiling part 412 of the guard main body 41.

[0021] In the fan 1 of the present invention having the above-mentioned configuration, the connector box 5 is provided on the peripheral wall 411 of the guard 4, so that the ceiling height of the guard body 41 in the guard 4 can be designed to be significantly lower than that of the conventional fan 100 as shown in Figure 6.

[0022] Therefore, in the blower 1 of the present invention, it is possible to design the thickness of the guard 4 (thickness (T) in the direction along the rotating shaft 21 of the motor 2) to be 40 mm or less (33.55 mm in this embodiment), which was impossible to achieve with the conventional blower 100.

[0023] <Inventive clothing 10> FIG. 4 shows garment 10 of the present invention equipped with blower 1 of the present invention. Garment 10 of the present invention has blower 1 of the present invention attached to garment body (W). Garment 10 of the present invention sends outside air into garment body (W) by generating an air flow from the outside to the inside of garment body (W) using blower 1 of the present invention, thereby cooling the inside of garment body (W). In this embodiment, garment 10 of the present invention is constructed by drilling holes in multiple places (two places) in garment body (W) and attaching blower 1 of the present invention to each hole.

[0024] As shown in Figure 5, the garment 10 of the present invention having the above-mentioned configuration is equipped with the blower 1 of the present invention in which the thickness (T) of the guard 4 is 40 mm or less, so that the garment body (W) protrudes less inward, and as a result, the rough feel that occurs in garment bodies (W) equipped with conventional blowers 100 is alleviated.

[0025] In the present embodiment, the thickness (T) of the blower 1 of the present invention is designed to be 33.55 mm, but it has been confirmed that the comfort of the garment 10 of the present invention is improved if the thickness (T) of the blower 1 of the present invention is 40 mm or less (preferably 30 to 35 mm).

[0026] The present invention can be implemented in various other forms without departing from its spirit or main features. Therefore, the above-described embodiments are merely illustrative in all respects and should not be interpreted as being limiting. The scope of the present invention is defined by the claims and is not limited to the text of the specification. Furthermore, all modifications and changes within the scope of the claims are within the scope of the present invention. [Industrial Applicability]
