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 for drying wet scalp hair, and when power is applied from the outside, air is introduced into the outside to form a wind therein, and then the wind is discharged to the outside. Depending on the discharge of cold or hot air.

Such a hair dryer generally includes a case in which a blowing flow path is formed therein, a blowing fan for discharging the wind that forms wind by introducing external air from the inside of the case, and a motor unit for rotating the blowing fan; When the hot air is required, the heater is installed in the air flow passage, and is configured as a heater that is heated to transfer the heat to the wind to heat the wind.

Conventionally, a coil heater is mainly used as a heating means of a hair dryer. A conventional coil heater is known to have a problem of generating a large amount of electromagnetic waves when a hair dryer is used. Recently, a ceramic heater is used to replace the coil heater. Development of the hair dryer is being made.

The ceramic heater is composed of a ceramic heat generating member that generates heat by directly applying electricity and heat dissipating member that discharges heat from the ceramic heat generating member to the surroundings and transfers heat to the wind formed in the hair dryer. Is pressed into the surface contact state for efficient heat transfer.

At this time, when excessively compressed in order to ensure close contact between the ceramic heat generating member and the heat radiating member, the ceramic heat generating member may cause cracks and breakage, which is a serious failure of the hair dryer.

Therefore, in order to prevent damage to the ceramic heating member due to the pressing during the manufacture of the ceramic heater, Korean Utility Model Model No. 20-2011-0006463 has a mounting groove for receiving the ceramic heating member inside the heat dissipation member. However, it is not easy to manufacture the width, height and height of the seating groove precisely by matching the width, length and height of the ceramic heating member, 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 decrease in energy efficiency.

On the other hand, the hair dryer is usually manufactured to include a temperature control sensor, but the ceramic heating element, which is a part of direct heating, heats up to 600 to 700 ° C when electricity is applied, so that burns and hair dryers are caused by such a high temperature. It causes deformation of appearance.

Therefore, although the heat shield member is installed inside the conventional hair dryer, the heat shield member of the hair dryer is fitted to the inside of the hair dryer without a separate fixing means as disclosed in Korean Utility Model No. 20-1996-0009786. Combination or simple fixing is made by the hook groove, which causes a problem that the thermal barrier member is separated during operation of the hair dryer, and furthermore, burns due to high heat transmitted directly from the heat generating means, deformation of the appearance of the hair dryer, etc. are generated. There is a limit to blocking the problem.

In general, the ceramic heater is to generate heat by winding the heating wire wound on the ceramic coated heating portion, there is a far infrared ray emitting effect, there is a strong heat resistance has the advantage that can be used for a long time. In addition, there is an advantage that allows fast and direct heat transfer. On the other hand, the ceramic heater has a disadvantage in that the thermal efficiency is slightly higher than the power consumption. Therefore, in the apparatuses using the ceramic heater as a heating means, various attempts have been made to increase 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 radiating means for transferring the heat of the ceramic heater to the outside to provide a durable and safe hair dryer.

1 is a perspective view for showing the overall configuration of the hair dryer according to the 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 blowing 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 the 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 significantly limited if the same configuration of a general hair dryer.

As shown in FIGS. 2 and 3, the electric heating element 500 includes a plate heat generating member 510, a first heat radiating member 530, a second heat radiating member 550, and a spacer 570.

Specifically, the plate heating member 510 is composed of at least one plate heater, each plate heater is configured to be controlled individually. More specifically, the plate heater includes a plate ceramic heater. The plate heating member 510 may use one plate heating member 510 or two or more plate heating members 510 in a plate shape in succession.

In this case, in order to efficiently control the amount of heat generated according to the degree of electricity applied, it is preferable to use two or more plate-shaped heat generating members 510, and each plate-shaped heat generating member 510 is controlled to be separately supplied with electricity. It is configured to be. More preferably, it is preferable to control the temperature of the wind of the hair dryer 10 using the three plate heating elements 510 in terms of the temperature of the normal hair dryer wind in the range of strong, medium, low and cold winds. good.

Hair dryer 10 of the present invention is separately configured control means for controlling the temperature of the wind of the hair dryer, but is not significantly limited.

In addition, the first heat dissipation member 530 and the second heat dissipation member 550 are disposed to be in contact with each other on one surface of the plate heat generating member 510 facing 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-shaped heat dissipation member 510 interposed therebetween. At this time, in order to efficiently transfer the heat generated from the plate heat generating member 510, the plate heat generating member 510 and the first and second heat dissipating members (530, 550) are formed in a state in close contact with the surface closely. .

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

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

Specifically, the first heat dissipation member 530 may include a first heat dissipation body 531 in surface contact with one surface of the plate-shaped heat dissipation member 510 and a plurality of heat dissipation plates extending to one side from the first heat dissipation body 531. 533, and the second heat dissipation member 550 extends from the second heat dissipation body 551 to the other side of the plate heat dissipation member 510 and to the other side of the second heat dissipation body 551. And a plurality of heat sinks 553.

Here, the first heat dissipation main body 531 and the second heat dissipation main body 551 are directly in surface contact with the plate heat generating member 510 and directly receive heat generated from the plate heat generating member 510. In addition, the plurality of heat dissipation plates 533 and 553 respectively 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. Received further to increase the temperature of the air introduced into the housing 100.

In this case, the plurality of heat sinks 533 and 553 are arranged to be spaced apart from the space within the housing 100 so as not to impede the flow of air while efficiently transferring heat to the air. Specifically, the first heat dissipation body 531 and the second heat dissipation body 551 are preferably formed in a vertical direction, and the heat sinks 533 and 553 are parallel to each other in order to smooth the flow of air. It is good to be placed.

Meanwhile, according to another embodiment of the present invention as shown in FIGS. 4 and 5, 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 dissipation member 530, the first heat dissipation main body 531 which is in surface contact with one surface of the plate-shaped heat generating member 510, and extends to one side from the first heat dissipation main body 531, the housing ( A second heat dissipating body including a plurality of heat dissipating plates 533 spaced apart from each other at different heights according to an inner space of the second heat dissipating member, and the second heat dissipating member 550 is in surface contact with the other surface of the plate-shaped heat dissipating member 510. 551, and a plurality of heat sinks 553 extending from the second heat dissipation body 551 to the other side and spaced apart from each other at different heights according to the internal space of the housing 100.

In detail, the shape of the interior 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 shown in FIG. 1, the interior space of the housing becomes a flat shape. In the case of a nozzle having a round cross section, the inner space of the housing is round. Here, the plurality of heat dissipation plates 533 and 553 respectively extending from the first heat dissipation body 531 and the second heat dissipation body 551 fills the interior space of the housing 100. In this case, the heat dissipation can be efficiently utilized by utilizing the internal space of the housing. In order to improve the effect, the heights of the heat sinks 533 and 553 spaced apart according to the shape of the inner space of the housing 100 may be different from each other.

Meanwhile, a spacer 570 is disposed around the plate heating member 510. The spacer 570 has a hollow part corresponding to the size and shape of the plate heat generating member 510, and fixes and supports the position of the plate heat generating member 510 while simultaneously enclosing the plate heat generating member 510 in the hollow part.

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

As described above, pressure is generated in the plate heating member 510 and the spacer 570 disposed inside while manufacturing the electric heating element 500 to be compressed. In this case, the spacer 570 is formed around the plate heating member 510. As it is arranged, the spacer 570 disperses the pressure applied to the plate heating element 510 in the pressing for the surface contact between the plate heating member 510 and the first and second heat dissipating members 530 and 550. As a result, the situation in which pressure is continuously applied to the inner plate-like heat generating member 510 to maintain the surface contact between the plate-like heat generating member 510 and the first and second heat dissipating members 530 and 550 is eliminated. Breakage of the 510 can be prevented. In addition, since the spacer 570 is in contact with the first and second heat dissipation members 530 and 550, respectively, the spacer 570 also transmits heat from the plate heat dissipation member 510 to the first and second heat dissipation members 530 and 550, respectively. The temperature of the first and second heat dissipation members 530 and 550 may be maintained uniformly.

In particular, even when the spacer 570 is disposed around the plate heat generating member 510, the plate heat generating member 510 and the first and second heat dissipating members are still in view of efficiently dissipating heat generated from the plate heat generating member 510. Surface contact with 530 and 550 may be ensured. In addition, at the same time, the thickness of the spacer 570 is preferably the same as the thickness of the plate-like heating member 510 in terms of the spacer 570 to efficiently distribute the pressure of the plate-like heating member 510, but when a tolerance occurs It is desirable to design smaller. Specifically, when the thickness of the plate heat generating member 510 is smaller than the thickness of the spacer 570, it is preferable that the difference does not exceed 10% based on the thickness of the plate heat generating member 510. That is, when the thickness of the spacer 570 is thicker than the plate-like heat generating member 510, there is no surface contact with the first and second heat dissipating members 530 and 550, and the thickness of the spacer 570 is greater than that of the plate-like heat generating member 510. If too thin, it is not preferable because it can not act as a pressure distribution or heat transfer medium applied to the plate heating element. That is, when the thickness of the plate-shaped heat generating member 510 is 1.5mm, it is most preferable to form the thickness of the spacer 570 about 1.4mm (the thickness difference is about 5%), and the thickness of the spacer 570 is the plate-like heat generating member ( Although slightly thinner than 510, contact is made with the first and second heat dissipation members 530 and 550 by the coupling force of the rivets at the outer edge portion of the spacer 570.

In addition, the spacer 570 maintains surface contact with the first and second heat dissipating members 530 and 550 while the plate heat generating member 510 maintains pressure applied to the plate heat generating member 510. The heat exchange between the 530 and the second heat radiating member 550 is preferably made of a material having a certain elasticity and thermal conductivity, and specifically, 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, considering the manufacturing cost of the hair dryer 10, the weight of the hair dryer 10 and the like is best made of an aluminum alloy.

In addition, in order to improve the thermal conductivity of the spacer 570, at least one of aluminum, gold, silver, copper, carbon nanoparticles, and carbon nanotubes may be contained. 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 includes a heat blocking means 590 between the housing 100 and the electric heating element 500 to prevent the heat of the electric heating element 500 from being directly transmitted to the housing 100. It may include. By the heat blocking means 590 to effectively block the high heat of the electric heating element 500 directly transmitted to the housing 100, to improve the operability of the hair dryer 10 and to use 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. Specifically, as shown in FIGS. 2 and 3, the spacer 570 may include the housing 100. It may be a part in contact with. More specifically, it may be a shape 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 preferably made of a silicon material in terms of being easy to be fitted to the side of the spacer 570 while ensuring the heat blocking efficiency.

On the other hand, according to Figure 6, the mounting groove 150 for mounting the electric heating element 500 on the inner surface of the housing 100 may be further formed, whereby the heat of the electric heating element 500 seating groove 150 The heat shield 590 may be disposed between the electric heating element 500 and the seating groove 150 of the housing 100 in order to prevent the direct transmission to the housing 100 through). In addition, as the seating grooves 150 are formed, the electric heating element 500 is stably mounted inside the housing 100, so that when the user operates the hair dryer 10, the electric heating element 500 or the heat blocking means 590. ) Can be prevented from coming off.

' 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 in that it has a substantially 'c' shaped cross section to be fitted to the seating groove 150 while surrounding the side of the electric heating element (500). At this time, the approximately 'ㄷ' cross section means' ㄷ 'shape,' U 'shape,'

'It may include all of the shape of the, if the form is easy to fit in the mounting groove 150 while surrounding the side of the electric heating element 500 is not greatly limited. Here, the side of the electric heating element 500 may refer to the side of the spacer 570 protruding from the electric heating element 500.

During operation of the hair dryer, the heat of 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 as it is, thus deforming the case. As this occurs, the role of the thermal cutoff means 590 is quite important.
