The present invention relates to a portable hair dryer using LP gas, which is composed of a thin body, which is easy to carry and store, and is soft and one-touch, so that it can be used for ignition and blowing. It is characterized by low production cost and no trouble.

Conventional hair dryers using LP gas have been devised in various types but have not been put to practical use due to structural defects, unreasonable production costs, problems in use, etc.

First, Utility Model Application No. 91-20244 filed by the present applicant uses a replaceable gas container, and a handle is configured in the body like a conventional hair dryer, and a rechargeable battery and a plug are housed inside the handle, and a simple burner It is designed inside the body and has a switch for gas control and ignition, a motor with a fan, a thermal sensor and a bimetal for overheating prevention.

It is inconvenient as a portable because of its large body and a protruding handle, and it is inconvenient to exchange gas, and a simple burner is used to detect incomplete combustion and ignition difficulty. This was eventually rejected by the Korean Utility Model Publication No. 91-127.

The design of the above publication No. 91-127 has a catalyst combustion body inside a round body with a handle and a motor with a fan inside, and a rechargeable battery, a transformer and a gas container are formed inside the handle. It is not practical because of the problems such as the effect is unclear, the amount of heat emitted is small, the structural defect of the ignition and gas control switch, the overall structure is coarse, and the body is large and not suitable for portable use.

Next, the hair dryer of Japanese Laid-Open Patent Publication No. 89-198507 has a structure similar to that of the above-mentioned Korean Utility Model No. 91-127. The inside of the round body with a handle is a fan-attached motor and battery, and a simple structure The burner is installed in front of the upper motor and the inside of the handle is formed by a gas bucket.

Also, there is a defect in the operation switch part, which makes it difficult to operate, the structure is coarse, the body is dull, and it is inconvenient to use, and it is not suitable for portable use, and there is a problem such as incomplete combustion phenomenon and splashing of fire by adopting simple burner It didn't work.

Next, Japanese Utility Model Publication No. 88-150604 has a rectangular parallelepiped body having the same horizontal and vertical dimensions and a height of about half of the horizontal dimension, storing batteries, forming a gas cylinder and a gas spray nozzle, and forming a blower type. It is a hair dryer equipped with a fan with a fan and a heat sink, and when gas is injected into the gas spray nozzle, it ignites it and causes the fan to rotate to release heat, which also has the disadvantage of incomplete combustion and sparks. The method of controlling the amount of ejection of the gas by using a rack gear is inconvenient, and it is not easy to operate. The body is dull and uncomfortable to carry.

Next, Japanese Laid-Open Patent Publication No. 86-31104 has a form in which a handle is attached to the lower side of a round body, and the front half of the body is rotated to the left and right to serve as an on / off switch, and the inside of the handle is a gas passage battery. The body is also equipped with a motor with a simple burner and fan, and there is no control switch attached to the handle.

It is recognized that the switch operation technology that rotates the body to be operated is different from that of a general hair dryer, but due to the simple structure of the burner, there are disadvantages such as incomplete combustion, sparking, and lack of calories. It is uncomfortable and has a poor structure, which has not been put to practical use.

In addition, the conventional hair dryers described above are installed on the same center of gravity of the body as the center of the body (that is, the burner is completely laid), and the other structure is described while the burner is configured to be perpendicular to the center of the body. Gas-type hair dryers, similar to the hair dryers in bars, have also been devised, which have a closed end that easily extinguishes flames, exposes problems such as sooting, incomplete combustion and sparking, and is not suitable for portable use due to the large and dull body. It has not been put to practical use.

Common features of the conventional gas-type hair dryer described above are as follows.

1) The burner structure is too simple, that is, by using a burner of one cylindrical shape (simple can type), there is a problem of incomplete combustion, the heat is insignificant, and the ignition is not easy, and soot is generated. There is a splashing phenomenon.

2) It is not suitable as portable because the body is dull and large in diameter, especially the handle is largely exposed and attached to the body.

3) The structure of operation switch is coarse and the performance is degraded, resulting in lack of safety and high failure rate.

4) The production cost is high because the overall structure is complicated.

Due to the above reasons, the conventional gas-type hair dryer has not been put to practical use. The present invention solves the problems and disadvantages of the above-described conventional products, and is newly devised to provide a gas-type hair dryer suitable for portable use. The configuration will be described with reference to the accompanying drawings.

The flat streamlined body 10 is composed of an upper body 11 and a lower body 12 and they are symmetrical with each other so that the protrusions 280 and the vent holes 13 and 14 are formed, respectively, inwardly. The partition 17 is formed so that the upper portion of the accessory chamber 250, the lower portion of the combustion chamber 30, the rear battery chamber 15 is formed in the lower battery compartment to form a battery 270, Allow the battery compartment cap 16 to be assembled and install the motor 180 with the fans 190 and 191 attached thereon before and after, and then, in the rear of the accessory chamber 250, the rechargeable gas cylinder 170 is installed. The gas connecting pipe 160 is attached to the end thereof, the hole 51 is formed in the center thereof, and the hole 54 penetrates through the concentric shape thereof. It is inserted and welded into the hole 54 of the valve 50 having the groove 52 in the form and the hole 53 formed therein so as to penetrate therein, and then into the hole 51 of the valve 50, the elbow type hole The shaft 60 is formed to allow the jaw 61 portion of the shaft 60 to be inserted to have the jaw 61 attached to the outside and having the rubber 63 attached thereto. After assembling the knob 40 as a key, the shaft 60 is assembled to the projection wall 19 to rotate through the bushing 200 so as not to be detached to the snap ring 210, the left and right sides of the upper knob 40 The contact plates 70 and 80 of the long end are inserted into the contact plate insertion grooves 41 and 42 to be bonded to each other, and the knob 40 is positioned between the protruding walls 18 and slightly exposed to the outside. 18, the motor operation welding point 90 and the lighter operation welding point 100 are formed so as to be in electrical contact with the battery power by the contact of the contact plates 70 and 80 of the upper and lower stages. The gas introduction pipe 150 is inserted and welded into the hole 53, and the vent hole 151 is formed in the straight portion thereof, and the air suction pipe 130 formed with a plurality of holes 131 is welded to the outer circumference thereof. The end of the inlet pipe 150 is welded to penetrate the center of the burner 140 having the lighter 260, and the capsule-type gas dispersion 141 is attached on the inner center line of the burner 140 to disperse the gas. At the same time, the end of the lighter 260 and sparks are easily generated, and the outer periphery of the burner 140 attaches the mesh 144 and 145 of different lengths in duplicate, and the outer periphery includes a plurality of through holes ( Attached to the rectangular burner cover 142 having a 143, and describes the operation and effect of the present invention by forming a mesh 20 in front of the combustion chamber 30.

The present invention has a structural feature of eliminating the handle and the body 10 has a flat shape to form a streamlined shape, so it is easy to carry and very light in weight, so it is convenient to use.

Knob 40 performs three functions of motor operation, ignition of the lighter, and gas discharge amount control at the same time. The long contact plate 70 is attached to the left side of the knob 40 and the short contact plate 80 is attached to the right side. The motor operation welding point 90 formed on the protruding wall 18 and the lighter operation welding point 100 are connected to each other to serve to connect the battery power source.

Of course, the stopper for limiting the rotation distance of the knob 40 is installed in the body 10, which is omitted in the illustration.

In order to use the present invention, when the knob 40 is rotated slightly downward in the state of FIG. 2, the jaw 61 at the end of the shaft 60 also rotates as the shaft 60 rotates. The hole 62 of the stays in the lower portion of the groove 52 of the valve 50 while moving slightly upward, and passes a small amount of gas through the gas introduction pipe 150.

At this time, the contact plates 70 and 80 are not yet in contact with the motor operation welding point 90 and the lighter operation welding point 100, which are divided into two points, respectively. The hole 62 of the jaw 61 is moved above the groove 52 of the valve 50, so that the amount of ejection of the gas is further increased.

At the same time, the contact plates 70 and 80 contact the motor operating welding point 90 and the lighter operating welding point 100 to conduct electric current so that the motor 180 rotates and the lighter 260 as shown in FIG. ) Generates a spark by using the upper point of the gas dispersion 141 as an earth and at the same time the gas is ignited.

The gas dispersion body 141 is a rectangular circular body made of a capsule type, so that when the gas escapes the end of the gas introduction pipe 150 and hits it, it is caused to vortex and disperse in the burner 140 by dispersing the gas. Since it is not ejected in a straight line but is dissipated as the pressure is weakened due to the gas dispersion 141, it stays inside the mesh 144 and 145 for a short time without passing through the mesh 144 and 145. Release.

Only in this state is the gas ideally ignited.

The reason for this is that the LP gas is condensed at a low temperature and is ejected through the gas introduction pipe 150, so the temperature is very low, so even if the writer 260 is operated at the end of the pipe being ejected, the gas is ignited. Because it does not become.

Therefore, while dispersing the ejection pressure of the gas by using the gas disperser 141, the inside of the mesh (144, 145) stays for a while to raise the temperature of the gas and at the same time it is properly mixed with air, so as to easily ignite the concentration. To make adjustments.

In this way, once ignited, combustion continues in the most ideal state thereafter.

Therefore, the burner structure of the present invention becomes a very important part. The burner of the present invention does not simply burn the gas using the can type burner, that is, the gas is simply burned inside the burner, but is burned or burned like an industrial gas burner. There is a feature that can be burned with a strong combustion force without this occurs to release a sufficient amount of heat.

When the gas starts to burn and the heat is released, the knob 40 is further rotated to increase the amount of heat emitted by the gas, which increases the amount of heat. In this state, as shown in FIG. 9, the contact plate 80 moves away from the lighter operation welding point 100. Stop further spark maintenance.

If the spark is maintained continuously, the life of the lighter will be greatly shortened, and the spark noise will continue to be annoying, and it will not be desirable because there is a problem such as draining the battery in a short time.

Therefore, once the ignition is further rotated the knob to increase the amount of heat the contact plate 80 will be out of the lighter operation welding point (100).

When the ignition is completed, it is preferable to rotate the knob to the maximum and maximize the amount of gas discharged so that the maximum heat is released.

The valve 50 has some depth at the side of the hole 51 A groove 52 is formed and a hole 52 is formed to penetrate the gas 52 through the hole 53 and the gas is discharged into the gas introduction pipe 150. In the early stage, the amount of gas discharged is reduced, and then the amount of gas released is enlarged or maximized, so that the gas-type hair dryer is suitable.

In the jaw 61 of the shaft 60, an elbow hole 62 is formed to act as a gas passageway, and the rubber 63 is attached to the outer surface of the jaw 61 to prevent gas leakage. And keeps the rotational friction force of the knob 40 appropriately.

A vent hole 151 is formed in a straight portion of the gas introduction pipe 150, and an air suction pipe 130 having a plurality of through holes 131 is attached to an outer circumference thereof.

The vent 151 of the gas introduction pipe 150 serves to allow the gas to be properly mixed with the air before entering the burner 140, which is similar to the role of the choke valve in the car cabretta of the vehicle. Do.

The diameter and number of the air vent 151 is configured to be calculated in proportion to the required calories, which plays an important role in the function of the hair dryer.

The air suction pipe 130 is to prevent the air inside the combustion chamber 30 directly into the vent hole 151, which has a function of slowing down the inflow rate of air.

In other words, it is to properly control the speed and inflow of the air flowing into the vent 151, which is also the number and diameter of the through-hole 131 is calculated proportionally to the required calories and plays an important role.

Fans 180 and 191 are attached to the motor 180 before and after, which is sufficient for supplying air volume, and using two fans with a smaller diameter than when using only one fan with a large diameter may result in no air supply. Without significantly reducing the thickness of the body 10 can eventually contribute greatly to the pursuit of a thin body, one of the features of the present invention.

And the upper body 11 and the lower body 12 is formed with a protrusion 280, the protrusion 280 is formed by the space portion occupied by the motor 180 and the fan 190, 191 and the body 10 The rest of is to be as thin as possible.

Vent holes 13 and 14 above and below the body 10 are preferably formed to have sufficient inflow of air, which further has the advantage of being able to faithfully perform a cooling function.

Forming a heat sink in the combustion chamber 30 to prevent excessive heat is transmitted to the body 10 is a common technique and the burner cover 142 is fixed to the heat sink by a suitable means is omitted in the drawings of the present invention It was.

This design works with the structure as above, the structure is omitted, the handle is thin, so it is ideal as a portable and light weight, it is also suitable for portable and convenient to use, eliminating the disadvantages of the large and blunt disadvantages and inconvenience of the conventional products. It is easy to ignite and adopts a new burner that has the characteristics of completely burning and releasing strong heat, completely eliminating the problems caused by the burner of the conventional product, and simplifying the valve structure and knob connection technology. It ensures reliable operation, thereby eliminating structural shortcomings, instability and high failure rate of valves and operation switches, and also provides ideal combustion and soot generation by applying air inhalation technology and gas dispersion vortex technology to properly mix air and gas. And prevention such as prevention, enough calorie production There are a number of useful effects with the production cost will with properties that can be put to practical use immediately with a lower benefit.
