JP7672102B2 - Air blower for cooling inside clothes, clothes with air blower - Google Patents

Description

The present invention relates to an internal clothing cooling fan that is attached to a clothing body and blows outside air into the clothing body, and to clothing equipped with a fan that is equipped with the internal clothing cooling fan.

Recently, clothing such as work clothes (hereinafter referred to as the "clothing body") is being commercialized as clothing with a fan (cooling clothing) that cools the inside of the clothing body by supplying outside air into the clothing body (see, for example, Patent Document 1 below).

JP 2019-214948 A

This type of clothing with a blower is designed so that the blower is attached to a hole drilled in an appropriate place on the body of the clothing, and outside air is sent into the body of the clothing through the blower. As shown in Figure 6, the blower 100 generally uses a motor 2 to rotate an impeller 3 (fan) with multiple blades, and the power to drive the motor 2 is supplied from a portable battery via a cable (C).

The blower 100 is structured so that the impeller 3 is surrounded by a guard 4 to ensure safety in handling. As shown in FIG. 7, when the blower 100 is attached to the 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.

Here, it would seem that the bulkiness of the blower 100 could be easily eliminated by simply making the motor 2 smaller and designing the guard 4 so that its thickness (thickness (T) in the direction along the motor's rotation shaft) is thin. However, because the guard 4 needs to be provided with a connector box 5 equipped with a connector 51 for connecting the terminal (C1) of the cable (C), it was practically impossible to design the thickness of the guard 4 to 45 mm or less.

The present invention was developed in consideration of the above technical problems, and aims to provide a new in-garment cooling fan that eliminates bulkiness, and a garment equipped with such an in-garment cooling fan.

The in-garment cooling fan of the present invention, which solves the above technical problems, is a fan that is attached to the garment body and blows 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").

In the preferred embodiment of the blower of the present invention, a connector box equipped with a connector for connecting the terminals of the battery is provided on the peripheral wall of the guard.

In the preferred embodiment of the blower of the present invention, the connector provided in the connector box is arranged parallel to the rotation shaft of the motor.

The clothing with a blower of the present invention, which solves the above technical problem, is characterized in that the blower of the present invention is attached to the clothing body (hereinafter referred to as "garment of the present invention").

The inventive blower eliminates bulkiness, improving the comfort of the inventive garment to which the inventive blower is attached.

The following describes embodiments of the present invention with reference to the drawings, but the present invention is not limited to these embodiments.

<Blower 1 of the present invention>
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.

-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.

- 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.

-Guard 4-
The guard 4 ensures safety during use of the blower 1 of the present invention by surrounding the periphery of the impeller 3. Since the guard 4 must be structured to allow the flow of air generated by the rotation of the impeller 3 to pass through, at least the portion of the guard 4 facing the front and back surfaces of the blades 32 of the impeller 3 is provided with mesh-like, net-like, or lattice-like openings. 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 portion 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.

As shown in FIG. 2, the fan 1 of the present invention is designed to receive power from a battery (B) via a cable (C). Therefore, the fan 1 of the present invention is further provided with a "connector box (5)" having a connector 51 for connecting the terminal (C1) of the cable (C).

- 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 portion 412 of the guard main body 41.

In the blower 1 of the present invention having the above configuration, the connector box 5 is provided on the peripheral wall 411 of the guard 4, so the ceiling height of the guard body 41 in the guard 4 can be designed to be significantly lower than in the conventional blower 100 shown in FIG. 6.

As a result, 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 40 mm or less (33.55 mm in this embodiment), which was impossible to achieve in the conventional blower 100.

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

As shown in FIG. 5, the garment 10 of the present invention having the above 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.

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

The present invention can be implemented in various other forms without departing from its spirit or main features. Therefore, the above-described embodiment is merely illustrative in all respects and should not be interpreted in a restrictive manner. The scope of the present invention is indicated by the claims and is not limited in any way by the text of the specification. Furthermore, all modifications and changes that fall within the equivalent scope of the claims are within the scope of the present invention.

The present invention is suitable for use as a means for cooling the inside of a garment body by supplying outside air into the garment body.
