Description

  For example, the present invention can be used for the inside of work clothes (outerwear) of workers (users) who perform various work outdoors under hot weather in summer, or for protective clothing (outerwear) such as firefighters (users). The present invention relates to an air blower in a jacket for effectively cooling the inside.

For example, various cooling devices have been proposed in order to prevent an increase in body temperature of a worker who performs work outdoors such as in the sun and to suppress a decrease in the efficiency of the work.
That is, a fan and a plurality of cooling agents are stored in a case having an air intake hole, and the case is stored in a back (back side) storage portion of a vest-like garment, and two ducts extending from the case Has been proposed in which the ends of these ducts are bent on the front side of the garment (see, for example, Patent Document 1).
However, since the case of the cooling device has a large flat plate shape with a length and width of 30 cm or less and a thickness of 10 cm or less, it is difficult to store the fan and the motor that drives the fan, and the position where the fan should be stored is There is a problem that it is limited to only the back storage part of the clothes and it is difficult to cope with a change in posture accompanying the work performed by the worker.

On the other hand, a fan, a motor, a battery, and a cooling agent are provided inside the blower body, and the air that has flowed into the fan body from the outer surface of the blower body is cooled by passing through the container containing the cooling agent. There has also been proposed a portable fan that can blow air to the outside from the exhaust ports on the upper surface and both side surfaces of the blower body, and that the blower body is hung on the neck with a strap (see, for example, Patent Document 2).
However, in the portable fan, since the fan, the motor, the battery, the coolant, and the storage container are housed in the blower body, the size of the body must be relatively large and heavy. As a result, there is a problem that a great feeling of fatigue is likely to be caused near the user's neck and it is difficult to cope with various operations.
Furthermore, in the cooling device and the portable electric fan described in Patent Documents 1 and 2, for example, in work such as under the hot sun in the summer, air for cooling is applied to local areas such as underarms, upper chest, or around the neck where sweating is remarkable. There was also a problem that it was difficult to blow air effectively.

JP 2012-237531 A (pages 1-8, FIGS. 1-6) Utility Model Registration No. 3165503 (Pages 1-12, FIGS. 1-8)

  The present invention solves the problems described in the background art and incorporates a sirocco fan and a motor in a box-shaped main body, and can effectively blow the air blown from the top wall of the main body locally such as under the armpit. Another object of the present invention is to provide a blower device in a jacket that can be easily mounted on the inner side of a user's jacket and has little trouble in work.

Means for solving the problems and effects of the device

In order to solve the above problems, the present invention is conceived in that only a sirocco fan and a motor are incorporated in a relatively small box-shaped main body, and the main body can be supported at an arbitrary position of a belt or a special belt. It was made.
In other words, an inner-blowing device of the present invention (Claim 1) is an inner-blowing device that blows an air flow between a user's outerwear and underwear or skin, and the air flow is changed to an outerwear. From a pair of inner and outer side walls, a top wall, a bottom wall, and a pair of left and right end walls that incorporate a sirocco fan that blows air between the underwear or the skin and a motor that drives the fan, and has a rectangular shape in side view A box-shaped main body configured; an air intake opening formed in at least one of the outer wall, the bottom wall, and the end wall of the main body; an air discharge opening formed in the top wall of the main body; and A holder or hook for a through-hole provided on an outer surface facing the underwear or skin side of the inner wall of the main body and supported by a belt of trousers, slacks, or a skirt, or a special belt; It is characterized by that.

  According to this, the box-shaped main body containing only the sirocco fan and the motor is supported by the user's trousers, slacks, skirt belt, or special belt by the through-hole holder or hook. The outer wall, the bottom wall, and at least one of the end walls of the air flowing in from the air intake port are used by the fan from the air discharge port opened in the top wall of the main body to be worn by the user. The air is blown between the garment and the underwear or between the garment and the skin. The blown air flow is blown locally such as under the user's armpit, upper chest, back, or around the neck to prevent the body temperature from rising, and by the latent heat of evaporation accompanying the evaporation of sweat sweat, An effective cooling effect can be given to the user. Moreover, the main body contains only a sirocco fan and a motor, and the battery for supplying power to the motor is accommodated in the belt, a special belt, or a pocket of an outer jacket or an undergarment, so that an arbitrary position desired by the user can be obtained. Can be easily and freely mounted. Accordingly, it is possible to prevent a user (operator) who performs various operations in hot weather or in a high-temperature environment from deteriorating the work efficiency due to high temperatures or sweating, and to perform the work safely and comfortably.

The outer garment includes various work garments worn during outdoor work, guard garments or protective garments worn by police officers or guardmen, or fire / heat-resistant protective garments worn by firefighters. Includes outerwear.
The underwear is worn on the inside of the outerwear and includes various underwear.
Further, the pair of inner and outer side walls in the box-shaped main body are rectangular (square or rectangular) in a side view.
The holder provided on the outer surface of the inner wall of the main body has a vertically long insertion hole for allowing the lateral belt of the belt or the special belt to pass therethrough.
Further, the holder provided on the outer side surface of the inner wall of the main body allows the belt or the lateral belt to pass therethrough, and the hook provided on the outer side surface of the inner wall of the box body is provided on the upper side of the belt, the lateral belt, the trousers or the skirt. It is erected downward.
In addition, the sirocco fan and the motor are preferably in the form of a storage case, which will be described later, in which both are unitized.

In the present invention, the special belt is a lateral belt that is wound horizontally around the chest and the back, and the sirocco fan and one or a plurality of the main bodies in which the fan is built in the lateral belt. In addition, an inner-blowing device (Claim 2) attached by the holder or hook is also included.
According to this, since the fan and the main body incorporating the fan are attached to the lateral belt of the special belt, the main body can be easily placed at a desired position in the vicinity of the chest and the upper back, which are higher than the belt such as trousers. Can be set. Therefore, it is possible to effectively and reliably give a cooling feeling to the user by effectively blowing air to the local area such as the armpit, the upper chest, or the neck area where the sweating action is remarkable.

Further, according to the present invention, the special belt includes a shoulder band having a pair of left and right sides on the chest side and a pair of left and right sides or one on the back side, and the lateral belt attached to a lower end of the shoulder band. The belt includes an inner-blowing device (Claim 3) that can be adjusted to a desired height by adjusting the length of the shoulder band.
According to this, since the height of the lateral belt can be easily adjusted, the fan and the main body incorporating the fan can be mounted at a desired position for each user, and it is more effective for the local area such as the armpit more reliably. Can be blown. Moreover, even when a plurality of the main bodies are used in combination, these weights can be sufficiently supported, so that a cooling feeling can be effectively and reliably given to the user for a long time.
In addition, the shoulder band in which the back side is converged to one is a band obtained by bundling (converging) a chest side and a pair of shoulders on the back side in a Y shape.

Further, in the present invention, a battery storage pocket to which a lead wire electrically connected to a motor built in the main body can be attached and detached is attached to the lateral belt of the special belt so as to be movable in the lateral direction. Also included is a blower in a jacket (Claim 4).
According to this, since the battery serving as the power source of the motor that drives the sirocco fan is housed in a pocket that is attached to the lateral belt so as to be laterally movable, the battery is brought into proximity with the main body in the same lateral belt. Easy to install in position. Therefore, safe and comfortable work can be performed without hindering the work of the user.
The power source of the motor is a battery connected to the tip of a lead wire extending from the box. The battery is not particularly limited, but from the viewpoint of output (electric power), usage time, and repeated use. For example, a rechargeable lithium ion battery is recommended.
In addition, the battery is always used by being inserted into the inner pocket of the user's outer jacket, the lead wire is led out from the gap between the buttons, and inserted into the sideways belt of the special belt or the storage pocket attached to the shoulder band. It is possible to move with the person.
Furthermore, the battery may be inserted into an outer pocket of the user's outer jacket, for example, so that the battery can always move together with the user.
The pocket is a bag-like body made of a resin or fiber having an upward opening, and the opening is flexible and has a planar locking tape that can be locked to the upper side of the pocket ( For example, it is closed with a lid sewn with a registered trademark: Velcro.
In addition, if a switch is arranged in the middle of the lead wire, the operation becomes easy.

Furthermore, in the present invention, the plurality of air discharge ports established in the top wall of the main body are formed by being divided into a plurality of discharge cylinders erected along different upward directions from the top wall. A jacket inner blower (Claim 5) is also included.
According to this, since a plurality of airflows can be blown along different upward directions from a single main body containing the sirocco fan and motor, for example, the user's armpit and chest upper part, or armpit and upper back part It becomes possible to give a more effective cooling feeling to a plurality of local areas.
Note that the plurality of discharge cylinders include a form having a V shape, a letter shape, a ↓ shape, or a U shape in a side view.

In addition, in the present invention, the main body is assembled by a pair of outer half body and inner half body obtained by dividing a top wall, a bottom wall, and a pair of left and right end walls into an inner side and an outer side, A plurality of positioning pins for supporting the sirocco fan and the motor housing case are provided on the inner side surface of either the inner half or the inner half so as to project inward and outward directions (Claim 6). ) Is also included.
According to this, the sirocco fan and the motor can be set accurately, quickly and surely at a predetermined position inside the main body. For example, the main body is injection-molded with a synthetic resin, or an Al alloy Mg alloy or the like. By die casting of light metal, it is possible to mass-produce at low cost with accurate shape and dimensions.
The plurality of positioning pins are individually provided in a plurality of through holes provided on the outer peripheral side of the sirocco fan and the motor housing case accommodated in the outer half body or the inner half body projecting inwardly. By inserting the storage case, the storage case is positioned.
Further, the positioning pin has a non-circular shape such as a regular polygon having a circular cross section and a tapered cone on the tip side, a regular polygon having a triangular shape or more, a cross shape, a star shape having five or more ridges, and the like. In addition, the tip side may have a tapered shape.
Furthermore, the air intake port is formed on almost the entire outer wall of the outer half of the main body, and the air flowing into the main body from the air intake port can flow into the center side of the sirocco fan. . However, even if most of the air intakes are blocked by the adjacent outerwear, sufficient air can be secured by the air intakes on the bottom wall and both end walls.
