Air conditioner clothes blower

Technical field

The present invention relates to a blower for air-conditioning clothing for blowing air into an air-conditioning clothing worn by workers who perform heavy labor such as road construction and light labor in a factory, for example.

Background art

The present inventors have devised a cooling garment that consumes less power and can be comfortably used even in a hot season (PCTZJP01Z01360). The powerful cooling garment includes a flow passage for allowing air to flow between the garment and the undergarment or the body, and a blowing means provided integrally with the garment. In this cooling garment, the body is cooled by the temperature difference between the body temperature and the temperature of the outside air by taking outside air into the flow passage by the blowing means and circulating the outside air. By simply wearing this cooling garment, the wearer can eliminate the heat. For this reason, if cooling clothing is widely spread, air conditioners will be almost unnecessary, and the contribution to global environmental protection will be extremely large. The cooling garment referred to here corresponds to the air-conditioning garment described in the present invention.

Disclosure of the invention

Problems to be solved by the invention

[0004] By the way, in general, the cooling effect obtained by wearing an air-conditioning garment differs depending on individual differences between wearers and intended use. For example, when the wearer engages in hard work, a sufficient cooling effect cannot be obtained unless a large flow of air is passed through the flow passage as compared with the case where the wearer engages in light work. Conventional air-conditioning garments do not take this into account; they merely flow a small amount of air between the garment and the underwear or body. Conventional air-conditioning garments made on the premise that a small amount of air is circulated were not comfortable for wearers under adverse conditions, such as those engaged in heavy labor. .

[0005] In addition, in most cases, the blower for air-conditioning clothing used for air-conditioning clothing is an existing fan. It is the current situation that is diverted. Therefore, in particular, a blower for air-conditioning clothes, which blows a large amount of air for the air-conditioning clothes, has hardly been developed so far.

[0006] The present invention has been made in view of such technical background, and an object of the present invention is to provide a blower for air-conditioning garments that is small and lightweight, and that can send a large amount of air into the air-conditioning garments. It is assumed that.

Means for solving the problem

[0007] In order to achieve the above object, an air conditioner / clothes blower according to the present invention includes a rotating body having a bladed impeller or a propeller for air blowing, and a bully for a rotating body attached to the rotating body. A motor that drives the rotating body, a motor pulley attached to the motor, a belt that is stretched over the rotating body pulley and the motor pulley, and a diameter of the rotating body pulley is: The diameter of the motor pulley is larger than the diameter of the motor pulley, and the ratio of the diameter of the rotator bully to the diameter of the motor pulley is at least 2: 1.

The invention's effect

[0008] According to the air conditioner / clothes blower of the present invention, the diameter of the pulley for the rotating body is larger than the diameter of the pulley for the motor, and the ratio of the diameter of the pulley for the rotating body to the diameter of the pulley for the motor is at least 2: 1. With this configuration, a large rotating body can be driven at a low speed rotation by using a small high-speed motor that can be driven by a heavy large motor, thereby reducing the size and weight of the entire configuration, and A large amount of air can be circulated in the air-conditioning clothing. Therefore, according to the present invention, the air conditioning that is optimal for use in air-conditioning clothing that cools the wearer's body using the physiological cooling function inherent in humans, in which the body is cooled by the heat of vaporization of sweat. A blower for clothes can be provided.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the best mode for carrying out the invention according to the present application will be described with reference to the drawings.

First, an air-conditioning garment to which a blower for an air-conditioning garment according to a first embodiment of the present invention is attached will be described. The air-conditioning garment according to the present embodiment uses a fan for the air-conditioning garment of the present embodiment to take in air outside the clothes and create a flow parallel to the surface of the human body, thereby cooling the body by the heat of vaporization of sweat. The human body can be cooled by effectively utilizing the cooling function.

[First Embodiment] FIG. 1 is a schematic front view of an air-conditioning garment equipped with an air-conditioning blower according to a first embodiment of the present invention, FIG. 2 is a schematic rear view of the air-conditioning garment, and FIG. FIG. 3 is a schematic rear view of an outerwear of a clothing portion of clothing. The air-conditioning garment 1 to which the air-conditioning blower according to the first embodiment of the present invention is attached, as shown in FIGS. 1, 2 and 3, has a cloth material portion 10 made of a material that does not transmit air, and a cloth material portion 10. Take in outside air inside and distribute a large amount of air An air conditioner / clothes blower (hereinafter, also simply referred to as a fan) 2, a power source 50 for supplying power to the fan 2, and a power cord 51 for electrically connecting the power source 50 to the fan are provided. The fan 2 is detachably attached by a magic hoop 16 to an opening 15 formed on the back of the clothing portion 10. The air taken in from the air inlet 21a by the fan 2 is discharged to the outside through the collar opening 11a and the sleeve opening lib, which are the opening 11 between the clothing material 10 and the wearer 100. In this embodiment, the lower end of the outer garment is fastened with a rubber belt to prevent air from leaking. However, the lower end may be opened and the lower end force may be discharged to the outside.

[0014] The air-conditioning garment 1 shown in Fig. 1 is a garment having long-sleeved outerwear and long pants. The long-sleeved outerwear is of a type whose front is closed with a fastener. Inside the outerwear, a pocket 12 for accommodating a power supply 50 necessary for driving the fan 2 is formed. As the power source 50, a secondary battery is used from the viewpoint of economy. A power switch (not shown) for turning on and off the power supplied to the fan 2 is provided between the power supply 50 and the fan 2.

[0015] As shown in FIGS. 2 and 3, a fan 2 is mounted in a slightly lower portion at the center of the back. In order to mount the fan 2, a large cut-out portion 15 is formed in the clothing material portion 10. Inside the periphery of the opening 15, a magic tape 16a for attaching the fan 2 is attached. The magic tape 16b is also attached to the fan 2 as described later, and the magic tape 16a, 16b allows the fan 2 to be detachably attached to the clothing portion 10.

[0016] In the present embodiment, since the long pants are already formed, detailed description will be omitted. The shape of the clothing portion of the present embodiment can take various forms depending on the purpose of use. For example, the air-conditioning garment to which the fan of the present embodiment is attached may be one in which the upper and lower portions are integrated like a jumpsuit that is not divided into upper and lower portions. In this case, the air also flows through the pants of the suit and the lower body is cooled.

Next, the flow of air when the air-conditioning garment 1 is worn will be described. As shown in Fig. 1 and Fig. 2, the air sucked from the air inlet 21a of the fan 2 attached to the opening 15 on the back, after flowing in parallel to the human body surface, Released from 11 outside. Next, the configuration of the fan 2 will be described in detail. 4 is a schematic perspective view of the fan 2 according to the first embodiment of the present invention, FIG. 5 is a schematic rear view of the fan 2, FIG. 6 (a) is a schematic front view of a fan guard of the fan, and FIG. b) is a schematic cross-sectional view of the fan guard in the direction of arrows A-A, FIG. 7 (a) is a schematic front view of the main body 20 of the fan 2 according to the first embodiment of the present invention, and FIG. FIG. 8A is a schematic front view of a rotary body with a pulley of a fan according to the first embodiment of the present invention, and FIG. 8B is a schematic right side view of the rotary body. It is a figure. The fan 2 includes a main body 20 and a fan guard 40. The main body 20 includes a base plate 21, a motor 22 mounted on the base plate 21, and a rotary body 30 with a pulley rotatably mounted on the base plate 21. A pulley 24 for the motor is attached to a rotating shaft of the motor 22. As shown in FIG. 7 (b), the motor 22 is attached to the base plate 21 via a vibration isolator 27 to prevent the vibration of the motor 22 from being transmitted to the base plate 21. The rotating body 30 with a pulley is rotatably mounted on the base plate 21 via a bearing 25. A belt 26 is stretched between the pulley 30a of the rotating body 30 with a pulley and the pulley 24 for the motor. The base plate 21 is provided with an air inlet 21a for taking in air and a finger guard 21b.

The finger guard 21b is provided to prevent a finger or the like from accidentally entering the air inlet 21a and coming into contact with the rotating body 30 to cause injury. A bearing 25 is attached to the center part 21c of the finger guard 21b. Therefore, the central portion 21c and the finger guard 2 lb require a predetermined strength for mounting the bearing 25. For this reason, in the present embodiment, the vertical finger guard 21b in FIG. 5 is formed wider than the horizontal finger guard in FIG.

[0020] As shown in FIG. 6, the fan guard 40 is provided on the side surface portions of the fan guard 40 so that the air taken in from the rotation axis direction by the pulley-equipped rotating body 30 can be efficiently and radially introduced into the clothing portion 10. A large opening 41 is formed in the gap. Also, circular openings 42 are formed on the upper surface of the fan guard 40 at a total of eight places. Since the upper surface of the fan guard 40 is a portion where the back of the wearer touches, an opening 42 is provided to prevent stuffiness. The fan guard 40 is fixed by the base plate 21 and the screw 43.

As shown in FIGS. 7 and 8, the rotating body 30 with a pulley is attached to the substrate 31 and the substrate 31. And a pulley 30a integrally formed on the outer peripheral portion of the substrate portion 31 with the substrate portion. In the present embodiment, the outer diameter of the pulley 30a and the outer diameter of the impeller 33 are substantially the same. The shaft 30a of the rotating body 30 with a pulley is fitted into a bearing 25, and is attached to the base plate 21 by the bearing 25. In the present embodiment, the outer diameter of the pulley 30a and the outer diameter of the impeller 33 are substantially the same, and the substrate 30 and the pulley 30a are integrally formed. Light weight can be achieved, and the configuration of the rotating body 30 can be simplified. Further, in the fan of the present embodiment, the rotating body and the pulley are integrally formed as compared with a conventional fan in which the rotating body and the pulley are separate parts, so that the assembling work is facilitated. .

A pulley 24 for the motor is attached to a shaft of the motor 22. A belt 26 is stretched between the pulley 24 and the pulley 30a of the rotating body 30. The rotational power of the motor 22 is transmitted to the rotating body 30 via the belt 26. Since the strength of the belt 26 can be small as described later, a rubber belt can be used as the belt 26. In this embodiment, since the belt 26 itself rotates at high speed, urethane rubber is used in consideration of durability.

As the motor 22, a motor that is small, lightweight, and rotates at high speed is used. For example, in order to obtain 5 W of power, a small motor requires about 10,000 revolutions, and a small motor with such a capacity generally weighs about 50 g. Conversely, a low-speed, high-power motor weighs about 1 kg, making it difficult to attach it to the air-conditioning garment 1.

The motor 22 is fixed to the base plate 21 with screws via a vibration isolator 27. The vibration isolator 27 is provided to prevent the vibration of the motor rotating at high speed from being transmitted to the base plate 21. For example, when the motor 22 rotates 10,000 times per minute, even if the axis of the motor is eccentric even a little, large vibration energy of high frequency is generated. If this vibration is directly transmitted to the base plate 21, it will be like a diaphragm of a base plate speaker. In order to reduce the vibration of the motor, the vibration isolator 27 is made of a material having a high anti-vibration effect, such as rubber.

By the way, as shown in FIG. 7 (a), the diameter R of the pulley 24 attached to the shaft of the motor 22 and the diameter R of the pulley 30a integrally formed with the impeller 33 are R <R, And R is a feather

2 1 2 2 It is preferable that the outer diameter of the vehicle 33 be 1Z2 or more. This is a light, small motor and large This is because, in order to obtain a high output, it is necessary to rotate the motor at a high speed and reduce the rotation speed of the large-diameter impeller 33.

[0026] For example, it is assumed that the power required to rotate the impeller having a large diameter of 150 mm and rotating at 1500 rpm used in the present embodiment is about 5 W (depending on the shape of the blade and the like). . In order to obtain this power of 5W, the number of rotations of the motor is required to be about 100 rpm. Therefore, in order to reduce the motor speed lOOOOrpm to the impeller speed 1500rpm, the pulley 24 and the pulley 30a use the belt 26. Therefore, the ratio of the diameters of the two pulleys of the present embodiment is R: R = 3: 20.

1 2

[0027] The required power can be represented by F X V (force X speed). Here, F (force) is a force applied to the belt (= force for rotating the pulley 30a), and V (speed) is a moving speed of the belt. As for F (force) and V (speed) necessary to obtain a predetermined power, it is preferable to increase V (speed) and decrease F (force). If F (force) is large, various problems occur. For example, the base plate 21 for mounting the motor 22 and the bearing 25 requires a large strength, and the belt 26 also requires a high strength. Further, the friction at the bearing 25 increases, and the energy loss increases. This causes problems such as shortening of the life of the device. To reduce F (force), the diameter of pulley 30a may be increased. By reducing the F (force) in this way, the force applied to the shaft of the motor or the like and the strength of the belt 26 can be reduced. If F (force) is reduced, V (speed) must be increased in order to obtain the required power. However, small motors that rotate at high speed are easily available, and urethane rubber belts must be used. The use does not cause a problem such as deterioration of the belt.

[0028] The fan 2 of the present embodiment has a capacity of about 40 liters Z seconds in the flow rate of air that can be sent out between the clothing portion 10 and the body or underwear. When the fan 20 sends out air with a flow rate of about 40 liters Z seconds into the clothing section 10, the pressure of the air automatically creates a space between the clothing section 10 and the body to allow air to flow in parallel with the body. Formed. Therefore, in such a case, the cloth portion 10 does not need a spacer or the like for securing an air flow passage.

[0029] In the case of the fan of the present embodiment, the amount of air to be sent can be increased or decreased by changing the diameter or the number of revolutions of the impeller. Figure 11 shows the fan wind with impellers of each diameter. It is a table | surface which shows an example of the value of the quantity, the maximum air-conditioning capacity, the actual capacity, and the amount of evaporation of sweat. The figure

In the table of 11, the number of rotations is set to an appropriate value according to the diameter of each impeller by increasing the number of rotations if the diameter is small and increasing the number of rotations if the diameter is large. In Fig. 11, the maximum air-conditioning capacity refers to the calorific value, which is a theoretical theoretical value, that can be absorbed per standard aerodynamic time passed through the space between the clothing area and the body. Here, standard air refers to air at a temperature of 33 ° C and a humidity of 50%. In addition, the actual ability refers to the amount of heat that can be actually absorbed by the air taken into the space between the clothing and the body, that is, the amount of heat that can actually contribute to the evaporation of sweat. Not all of the air taken into the space between the fabric and the body contributes to the cooling. Of the air taken in, the air that passes through a position at a distance away from the body is less likely to contribute to the cooling as the body goes away. Therefore, in the table in Fig. 11, 60% of the maximum air conditioning capacity is estimated as the actual capacity, and the values are shown. The amount of sweat evaporation refers to, for example, the maximum amount of sweat that a fan using an impeller with a diameter of 180 mm can evaporate in one hour. As shown in Fig. 11, a fan with a 180 mm diameter impeller can evaporate 2.8 liters of sweat per hour. Also, in the case of the fan of the present embodiment using a 150 mm impeller, as can be seen from FIG. 11, the air volume is 40 liters Z seconds, the maximum air conditioning capacity is 1568 kcal ZH, and the actual capacity is 941 kcal ZH The evaporation of sweat is 1.6 liters ZH. Therefore, if a worker who performs heavy labor wears the air-conditioning clothing of this embodiment, 1.6 liters of sweat can be evaporated in one hour, and the heat of vaporization at this time can be used to fully wear the wearer. Can cool the body.

Next, the operation of the fan according to the present embodiment will be described. The arrow A shown in FIG. 7 (a) indicates the rotation direction of the rotating body 30 with the pulley. When power is supplied from the power supply 50 to the motor 22, the motor 22 rotates, and this rotation is transmitted to the rotating body 30 via the belt 26. As a result, the rotating body 30 rotates in the direction of arrow A in FIG. 7 (a). Thus, air can be sucked in from the axial direction of the impeller 33 of the rotating body and can be radially sent out toward the outer periphery of the impeller 22b. Such a fan that radially sends out the air taken in from the axial direction of the impeller 33 toward the outer periphery of the impeller is also called a “turbo fan”. Further, the impeller having the structure of the present embodiment absorbs air from the axial direction of the impeller, regardless of whether it rotates in the left or right direction. And air can be radially sent out toward the outer periphery of the impeller.

Next, the operation of the air-conditioning garment of the present embodiment will be described. FIG. 9 is a schematic rear view of the fan for explaining the air flow of the fan according to the first embodiment.

[0032] When the wearer turns on the power switch (not shown), the fan 2 is connected to the fan 2 through the cord 51 from the power supply 50 stored in the inner pocket provided near the front chest of the clothing section 10 of the air-conditioning garment 1. Electric power is supplied to the motor 22, and the motor 22 rotates. When the motor 22 rotates, the pulley 24 attached to the shaft of the motor 22 also rotates, whereby the pulley 30a also rotates via the belt 26. When the pulley 30a rotates, the impeller 33 formed integrally with the pulley 30a also rotates. When the impeller 22b rotates, external air flows in from the air inlet 21a as shown in FIG. 9 and is sent out through all the openings 41 on the four side surfaces of the fan guard 30 into the cloth material portion 10. . The air sent out to the cloth part 10 by the fan 2 is approximately 40 liters Z seconds, so the space between the cloth part 10 and the body automatically passes by the pressure of the sent air. Is formed. The air delivered into the clothing portion 10 flows in parallel along the body surface of the wearer and is discharged to the outside through the opening portions 11 of the collar and the sleeve. In this way, the outside air is introduced into the clothing portion and flows along the body surface of the wearer, so that the wearer can be cooled by a large amount of cold outside air, and the sweat of the wearer is converted into water vapor. The air is discharged to the outside together with the air, thereby promoting the vaporization of the sweat of the wearer and cooling the body of the wearer by the heat of vaporization of the sweat.

[0033] According to the fan of the above-described embodiment, the rotation speed of the rotating body with a pulley can be reduced by using a small-sized and high-speed rotating motor. Since the force applied to the base plate, bearings, and the like can be reduced, the overall configuration can be simplified.

[0034] Further, according to the fan of the present embodiment, by integrally forming the rotating body and the pulley, the fan can be downsized, and the operation of fitting the rotating body and the pulley is performed. This makes assembly easier than conventional fans.

Further, according to the present embodiment, the diameter R of the pulley 24 for the motor and the diameter R of the pulley 30a integrally formed with the impeller 33 are R: R = 3: 20, and

2 1 2

Since R is almost the same as the outer diameter of the impeller 33, a large amount of air can be Can be sent into the clothing area.

Further, as shown in FIG. 5, the fan 2 of the present embodiment includes a magic tape 16 b attached to the back surface of the base plate 21 and a periphery of the edge of the opening 15 which is greatly opened on the back of the clothing material portion 10. It is attached to the cloth part 10 with the magic tape 16a attached inside. As described above, in the present embodiment, the fan 2 is attached to the clothing portion 10 using the velcro tape 16, so that the fan 2 is fixed firmly to the clothing portion 10 and the air of the attachment portion has a strong force. There is almost no leakage. Further, since the fan 2 of the present embodiment can be easily attached and detached, the air-conditioning garment 1 can be easily washed.

[0037] Further, in the present embodiment, a large amount of air can be sent out into the cloth portion by one motor, so that the cost performance is higher than when a plurality of motors are used. This is suitable for use in air-conditioning garments that need to blow air into the clothing base.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 10 (a) is a schematic front view of a rotating body with a pulley used for a fan according to a second embodiment of the present invention, and FIG. 10 (b) is a schematic right side view of the rotating body with a pulley, and FIG. c) is a schematic cross-sectional view of the pulley-attached rotating body as viewed in the direction of arrows B-B. Note that the fan of the first embodiment is different from the fan of the second embodiment only in a rotating body with a pulley. Therefore, in order to simplify the description, in the present embodiment, only portions different from the first embodiment will be described. In the second embodiment, components having the same functions as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In the rotary member 60 with a pulley of the second embodiment, a propeller 61 is used instead of the impeller 33 of the rotary member 30 with a pulley of the first embodiment. A pulley 62 is formed integrally with the propeller 61 on the outer periphery of the propeller 61.

[0040] The operation and effect of the present embodiment are the same as those of the first embodiment, and a detailed description thereof will be omitted.

[0041] The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the gist. For example, in the above embodiment, the case where the pulley of the rotating body is the same as the outer shape of the rotating body has been described. The pulley of the rotating body may be 1 Z2 or more of the rotating body. It is desirable that the pulley of the rotating body be within 1.5 times the diameter of the rotating body. If the rotating pulley is larger, the fan will be larger and This is because it becomes difficult to attach to clothes.

[0042] Further, the fan of the present invention is not limited to the case where a large amount of air is sent into the air-conditioning garment, but may send a small amount of air into the air-conditioning garment.

Further, the pulley of the rotating body is not limited to being formed integrally with the rotating body, and may be separate from the rotating body.

Further, in the above embodiment, the case where a fan having a blowing capacity of 40 liters Z seconds is used has been described, but the blowing capacity of the fan of the present invention depends on the pressure of the air to be sent out. Any capacity may be used as long as a space is automatically formed between the clothing portion and the body to allow air to flow in parallel with the body. Depending on the shape and material of the air-conditioning garment used, the required blowing capacity of the fan varies.To automatically form a space for flowing air, according to the inventor's test, at least 6 liters It is considered that the air blowing capacity is necessary. Also, it is not necessary to have a capacity of more than 100 liters Z seconds. As can be seen from Figure 11 above, 70 liters ZH can evaporate 2.8 liters of sweat per hour, so a blowing capacity of 100 liters Z seconds evaporates the sweat of workers who work hard. This is because the flow rate is sufficient for this, and the blowing capacity beyond this is over-specified and meaningless.

Industrial applicability

As described above, according to the air conditioner blower of the present invention, a small, lightweight, and large amount of air can be introduced into the air conditioner clothes. Therefore, the present invention is particularly applicable to air-conditioning garments used by standing workers, etc., who are working hard.
