Description

Hair dryer {A hair dryer}

The present invention relates to a hair dryer, and more particularly, to a hair dryer in which a plate heater is used as a heating means of the hair dryer.

A hair dryer is a device that dries the hair of wet scalp. When power is applied from the outside, the outside air is drawn into the inside to form wind in the inside, and then the wind is discharged to the outside. Depending on whether it is discharged by cold or hot air.

In general, such a hair dryer includes a case in which a blow passage is formed therein, a blower fan for drawing the outside air inside the case to blow out the wind forming the wind, and a motor unit for rotating the blower fan. , If hot air is required, it is installed in the air flow path and is composed of a heater that is a heating means for heating the wind to warm by transferring heat to the wind.

In the past, a coil heater was mainly used as a heating means for a hair dryer, but the conventional coil heater is known to have a problem of generating a large amount of electromagnetic waves when using a hair dryer, and recently, a ceramic heater is used to replace the coil heater. The development of hair dryers is being done.

The ceramic heater is composed of a ceramic heating element that generates heat by directly applying electricity, and a heat radiating member that discharges heat from the ceramic heating element to the surroundings and transmits heat to the wind formed in the hair dryer. Is compressed and formed in a surface contact state for efficient heat transfer.

At this time, when excessively compressed to ensure close surface contact between the ceramic heating member and the heat radiating member, cracks may occur in the ceramic heating member to cause damage, which is a serious defect of the hair dryer.

Therefore, in order to prevent damage to the ceramic heating element due to compression during the manufacture of the ceramic heater, Korean Utility Model No. 20-2011-0006463 forms a seating groove for receiving the ceramic heating element inside the heat radiating member. However, it is not easy to manufacture by precisely matching the width, height and height of the seating groove and the width, height and height of the ceramic heating element, which is disadvantageous in terms of the manufacturing process to reinforce the airtightness and durability of the ceramic heater. many. In addition, such a problem eventually causes a failure of the hair dryer or causes a reduction in energy efficiency.

On the other hand, although the hair dryer is usually manufactured to include a temperature control sensor, the ceramic heating member, which is a part that directly heats, generates heat up to 600 to 700 ° C when electricity is applied, so burns and hair dryers caused by the hair dryer due to the partial high heat It causes deformation of appearance.

Therefore, although a thermal barrier member was installed inside the conventional hair dryer, as shown in Korean Utility Model No. 20-1996-0009786, the thermal barrier member of the hair dryer is fitted inside the hair dryer without additional fixing means. Since it is combined or simply fixed by a hook groove, a problem occurs in that the thermal barrier member is detached during the operation of the hair dryer, and further, an image due to high heat transmitted directly from the heating means, deformation of the hair dryer, and the like occurs. There are limits to blocking the problem.

Korea Utility Model No. 20-2011-0006463 (2011.06.29) Korea Public Utility Model No. 20-1996-0009786 (April 12, 1996)

In general, the ceramic heater is to heat by winding a heating wire on a ceramic-coated heating portion, and has a far-infrared emission effect, and has a strong heat resistance, so that it can be used for a long time. In addition, there is an advantage that enables fast and direct heat transfer. On the other hand, ceramic heaters have a disadvantage in that the thermal efficiency is not high compared to the power consumption. Therefore, in devices utilizing the ceramic heater as a heating means, various attempts have been made to enhance the thermal efficiency while enhancing the advantages of the ceramic heater.

Accordingly, the present invention is to improve the stability and efficiency of the heat dissipation means for transferring the heat of the ceramic heater to the outside to improve durability and provide a safe hair dryer.

1 is a perspective view for showing the overall configuration of a hair dryer according to the present invention.

According to FIG. 1, the hair dryer 10 of the present invention includes a housing including an inlet 110 through which external air is introduced and an outlet 130 through which the air introduced through the inlet 110 is discharged to the outside. 100), a blower means 300 disposed in the housing 100 and flowing air from the inlet 110 to the outlet 130, and an electric heating element installed inside the housing 100 to heat air ( 500). At this time, the inlet 110, the outlet 130, the housing 100 and the blowing means 300 of the hair dryer 10 of the present invention is not greatly limited as long as it is the same configuration of a general hair dryer.

2 and 3, the electric heating element 500 includes a plate-shaped heating member 510, a first heat-radiating member 530, a second heat-radiating member 550, and a spacer 570.

Specifically, the plate heating element 510 is composed of at least one plate heater, and each plate heater is configured to be individually controlled. More specifically, the plate heater includes a plate-shaped ceramic heater. In addition, the plate heating member 510 may use one plate heating member 510 according to the intention of an operator, or two or more plate heating members 510 may be continuously used in a plate shape.

At this time, in order to efficiently control the amount of heat generated according to the degree to which electricity is applied, it is preferable to use two or more plate-like heating members 510, and each plate-like heating member 510 is controlled to be applied with electricity individually. It is configured as possible. More preferably, it is preferable to control the temperature of the wind of the hair dryer 10 by using three plate heating elements 510 in that the temperature of the normal hair dryer wind is made in a range of strong, medium, low and cold wind. good.

In the hair dryer 10 of the present invention, control means for controlling the temperature of the hair dryer wind are separately configured, but are not particularly limited.

In addition, the first heat dissipation member 530 and the second heat dissipation member 550 are respectively arranged to be connected to one surface of the plate-shaped heating member 510 opposite to each other. That is, the first heat dissipation member 530 and the second heat dissipation member 550 are connected to both sides with the plate-like heat generating member 510 therebetween. At this time, in order to efficiently transfer the heat generated by the plate-shaped heating member 510, the plate-shaped heating member 510 and the first and second heat-radiating members 530 and 550 are compressed and formed in close contact with each other. .

The first and second heat dissipation members 530 and 550 are preferably made of a metal material having high thermal conductivity while ensuring durability, corrosion resistance, and heat resistance in terms of effectively dissipating heat of the plate-like heat generating member 510. It may be made of at least one of aluminum, aluminum alloy, and stainless steel. More preferably, it is best to be made of an aluminum alloy in consideration of aspects such as the manufacturing cost of the hair dryer 10 and the weight of the hair dryer 10.

In addition, at least one of the first heat dissipation member 530 and the second heat dissipation member 550 to improve heat dissipation of the first and second heat dissipation members 530 and 550, aluminum, gold, silver, copper, and carbon nanoparticles , May contain at least one of carbon nanotubes.

Specifically, the first heat dissipation member 530, the first heat dissipation body 531 in surface contact with one surface of the plate-like heat dissipation member 510, and a plurality of heat dissipation plates extending to one side from the first heat dissipation body 531 (533), the second heat-radiating member 550, the second heat-radiating body 551 in surface contact with the other surface of the plate-like heat-generating member 510, and extending from the second heat-radiating body 551 to the other side It includes a plurality of heat sinks 553.

Here, the first heat dissipation body 531 and the second heat dissipation body 551 directly receives heat generated by the plate heat generating member 510 while making direct surface contact with the plate heat generating member 510. In addition, a plurality of heat sinks 533 and 553 extending to the first heat dissipation body 531 and the second heat dissipation body 551 are heat transferred to the first heat dissipation body 531 and the second heat dissipation body 551, respectively. It is further received to increase the temperature of the air introduced into the housing 100.

At this time, the plurality of heat sinks 533 and 553 are arranged to space the space within the housing 100 at regular intervals so as not to impede the flow of air while efficiently transferring heat to the air. Specifically, it is preferable that the first heat dissipation body 531 and the second heat dissipation body 551 are formed in a vertical direction, and the heat sinks 533 and 553 are parallel to each other to facilitate air flow. It is good to be placed.

Meanwhile, as disclosed in FIGS. 4 and 5, according to another embodiment of the present invention, the first and second heat dissipation members 530 and 550 of the electric heating element 500 are variable according to the shape of the hair dryer 10. It can be formed as. Specifically, the first heat-radiating member 530, the first heat-radiating body 531 in surface contact with one surface of the plate-like heat-generating member 510, and the first heat-radiating body 531 extends to one side and the housing ( 100) includes a plurality of heat sinks (533) spaced apart at different heights according to the interior space, and the second heat dissipation member (550), the second heat dissipation body that is in surface contact with the other surface of the plate heat generating member (510) 551, and a plurality of heat sinks 553 extending from the second heat dissipating body 551 to the other side and spaced at different heights according to the inner space of the housing 100.

In detail, the shape of the inner space of the housing 100 varies according to the shape of the hair dryer nozzle. For example, in the case of a flat nozzle as disclosed in FIG. 1, the inner space of the housing becomes a flat shape, and as another example In the case of a nozzle with a round cross-section, the space inside the housing becomes round. Here, a plurality of heat sinks 533 and 553 extending from the first heat dissipation body 531 and the second heat dissipation body 551 fill the interior space of the housing 100. At this time, the interior space of the housing is effectively utilized to dissipate heat. In order to improve the effect, the heights of the heat sinks 533 and 553 spaced apart according to the shape of the interior space of the housing 100 may be formed differently.

Meanwhile, a spacer 570 is disposed around the plate heating element 510. The spacer 570 has a hollow portion corresponding to the size and shape of the plate-shaped heating element 510, and while the plate-shaped heating element 510 is enclosed in the hollow portion, the position of the plate-shaped heating element 510 is fixed and supported.

Here, the combination of the spacer 570 and the first and second heat dissipation members 530 and 550 can be utilized without limitation as long as it is a connecting means that can be fixed in a compressed state, but is preferably combined by a rivet. . The coupling by the rivet can precisely control the degree of compression of the plate-like heating member 510 and the spacer 570 and the first and second heat-radiating members 530 and 550 by the tightening force, as well as the electric heating element 500 It can be made to be easily made.

In this way, pressure is generated in the plate-shaped heating member 510 and the spacer 570 disposed inside while manufacturing the electric heating body 500 to be compressed, wherein the spacer 570 is provided around the plate-shaped heating member 510. As it is arranged, the spacer 570 disperses the pressure applied to the plate-shaped heating member 510 in the pressing for surface contact between the plate-shaped heating member 510 and the first and second heat-radiating members 530 and 550. Accordingly, the situation in which pressure is continuously applied to the inner plate-like heating member 510 in order to maintain the surface contact between the plate-like heating member 510 and the first and second heat-radiating members 530 and 550 is resolved, and the plate-like heating member ( 510) can be prevented from damage. In addition, the spacer 570 is in contact with the first and second heat dissipation members 530 and 550, respectively, and thus serves to transfer heat from the plate-like heat dissipation member 510 to the first and second heat dissipation members 530 and 550, respectively. , It is also possible to maintain the temperatures of the first and second heat dissipation members 530 and 550 uniformly with each other.

Even though the spacer 570 is disposed around the plate-like heating member 510, the plate-like heating member 510 and the first and second heat-radiating members are still provided in terms of efficiently dissipating heat generated from the plate-like heating member 510. It is good to ensure surface contact with (530, 550). In addition, at the same time, the spacer 570 is preferably the same as the thickness of the plate-like heating member 510 in terms of dispersing the pressure of the plate-like heating member 510 efficiently, but when tolerance occurs It is desirable to design smaller. Specifically, when the thickness is smaller than the thickness of the plate-shaped heating member 510, the thickness of the spacer 570 is preferably not more than 10% of the difference based on the thickness of the plate-shaped heating member 510. That is, when the thickness of the spacer 570 is thicker than that of the plate-like heating member 510, surface contact with the first and second heat-radiating members 530 and 550 is not possible, and the thickness of the spacer 570 is greater than that of the plate-like heating member 510. If it is too thin, it is not preferable because it cannot act as a pressure distribution or heat transfer medium applied to the plate heating element. That is, when the thickness of the plate-shaped heating member 510 is 1.5 mm, it is most preferable to form the thickness of the spacer 570 to about 1.4 mm (with a thickness difference of about 5%), and the thickness of the spacer 570 is a plate-shaped heating member ( Even though it is slightly thinner than 510), contact is made with the first and second heat dissipation members 530 and 550 by the coupling force of the rivet at the outer edge portion of the spacer 570.

In addition, the spacer 570 maintains the surface contact with the first and second heat radiating members 530 and 550 while the plate-like heat generating member 510 maintains the pressure applied to the plate heat generating member 510, and the first heat radiating member In order to allow heat exchange between 530 and the second heat dissipation member 550, it is preferable that the material has a certain degree of elasticity and thermal conductivity, and specifically, it is preferably a metal material. More specifically, it is preferably made of a metal material having high thermal conductivity while ensuring durability, corrosion resistance, and heat resistance, and for example, may be made of at least one material of aluminum, aluminum alloy, and stainless steel. More preferably, it is best to be made of an aluminum alloy in consideration of aspects such as the manufacturing cost of the hair dryer 10 and the weight of the hair dryer 10.

In addition, in order to improve the thermal conductivity of the spacer 570, it may contain at least one of aluminum, gold, silver, copper, carbon nanoparticles, and carbon nanotubes. Accordingly, the spacer 570 and the first , 2 heat dissipation members 530 and 550 may be made of the same material.

The hair dryer 10 of the present invention further comprises a heat blocking means 590 between the housing 100 and the electric heating element 500 to prevent heat from the electric heating element 500 being directly transferred to the housing 100. It can contain. By the heat blocking means 590, the high heat of the electric heating element 500 is effectively blocked from being directly transmitted to the housing 100, thereby improving the operability of the hair dryer 10 and using a safe hair dryer 10. can do.

Here, the heat blocking means 590 may be disposed at a portion where the housing 100 and the electric heating element 500 directly contact each other, and specifically, as illustrated in FIGS. 2 and 3, the spacer 570 may include the housing 100. It may be a part in contact with the. More specifically, it may be in a form fitted to the side of the spacer 570.

At this time, the heat blocking means 590 may be formed of a heat insulating material, it may be preferable to be made of a silicon material in terms of ensuring heat blocking efficiency while being easy to fit on the side of the spacer 570.

Meanwhile, according to FIG. 6, a seating groove 150 for mounting the electric heating element 500 on the inner surface of the housing 100 may be further formed, and accordingly, the heat of the electric heating element 500 may be set. ) To prevent direct transmission to the housing 100, the heat blocking means 590 may be disposed between the electric heating element 500 and the seating groove 150 of the housing 100. In addition, as the seating groove 150 is formed, the electric heating element 500 is stably mounted inside the housing 100, and when the user operates the hair dryer 10, the electric heating element 500 or the heat blocking means 590 ) Can be prevented from deviating.

' 자형의 형태를 모두 포함할 수 있으며, 전기발열체(500)의 측면을 감싸면서 안착홈(150)에 끼워지기 용이한 형태라면 크게 제한되지 않는다. 여기서, 전기발열체(500)의 측면은 상기 전기발열체(500)에서 돌출된 상기 스페이서(570) 측면을 일컫는 것일 수 있다.The heat blocking means 590 may be characterized by having an approximately 'c'-shaped cross section so as to fit into the seating groove 150 while surrounding the side of the electric heating element 500. At this time, roughly 'U' shaped section means' U 'shaped,' U 'shaped,'

It may include all of the shape of the shape, if the shape that is easy to fit into the seating groove 150 while surrounding the side of the electric heating element 500 is not greatly limited. Here, the side surface of the electric heating element 500 may refer to the side surface of the spacer 570 protruding from the electric heating body 500.

During the operation of the hair dryer, heat from the heat generating member 510 is consumed to the outside through the heat dissipating members 530 and 550, but when the hair dryer is stopped, the high heat remaining in the heat generating member 510 is transferred to the case and the case is deformed. Since this occurs, the role of the heat blocking means 590 is very important.
