Disclosure of Invention
Problems to be solved by the invention
According to the dryer of patent document 1, power consumption can be reduced as compared with a conventional dryer using a nichrome wire heater as a heat source. Further, by blocking most of the visible light in the light emitted from the heat-ray light source with a filter, it is possible to eliminate the eyes of the user when the dazzling light enters the dry hair. However, when the dryer is continuously used, the filter may be damaged by heat accumulated in the filter and rapidly expand, and the fingertip may contact the filter near the air outlet and be burned, which causes problems in durability and safety. When the filter is damaged due to overheating, fragments of the filter may scatter from the air outlet and injure a person.
The invention aims to provide a dryer with excellent durability, which can reliably prevent the damage of an optical filter caused by heat even when the dryer is continuously used.
The invention aims to provide a dryer with excellent safety, wherein fingertips do not contact an optical filter and are not burned even though the fingertips enter the inside of an air outlet by mistake.
Means for solving the problems
In the dryer according to the present invention, a blower fan 3 that sends dry air toward an outlet 9, a light emitter 4 that serves as a heat source, and a reflector 10 that reflects and guides light emitted from the light emitter 4 toward the outlet 9 are disposed inside an air guide portion 7 of a main body casing 1. A filter structure 11 that blocks transmission of visible light among light emitted from the light emitter 4 is disposed on a light emission path between the reflecting mirror 10 and the outlet 9. The substrate glass 62 constituting the optical filter 60 of the filter structure 11 is characterized by being formed of a low-expansion glass.
The substrate glass 62 has a thermal expansion coefficient of less than 7X 10-6The low-expansion glass of any one of the above crystallized glass and quartz glass. The crystallized glass includes, for example, black crystallized glass, transparent crystallized glass, and in the case of a substrate glass 62 made of quartz glass or transparent crystallized glass, a multilayer film 71 is formed on one surface thereof to form the optical filter 60.
The optical filter 60 includes a substrate glass 62 and a multilayer film 71 laminated on one surface of the substrate glass 62, and the substrate glass 62 is formed of low-expansion quartz glass or transparent crystallized glass.
The optical filter 60 is disposed with the multilayer film 71 on the emission surface side of the substrate glass 62.
The substrate glass 62 is made of black crystallized glass in which β -quartz solid solution crystals are precipitated in the glass.
A plurality of optical filters 60 are disposed adjacent to each other with a gap E therebetween on the light radiation path between the reflecting mirror 10 and the outlet 9.
The filter structure 11 is composed of an optical filter 60 and a light transmitting body 61 arranged on a light radiation path between the optical filter 60 and the outlet 9. The light-transmitting body 61 is formed of a light-transmitting material through which infrared light passing through the optical filter 60 passes.
Effects of the invention
In the dryer of the present invention, a filter structure 11 for blocking transmission of visible light is disposed on a light emission path between the reflecting mirror 10 and the outlet 9, and a substrate glass 62 constituting an optical filter 60 of the filter structure 11 is formed of a low-expansion glass. According to such a dryer, the substrate glass 62 can be prevented from being thermally expanded by the heat of the light emitted from the light emitter 4 as much as possible. Therefore, even when the dryer is continuously used, damage of the optical filter 60 due to heat can be reliably prevented, and the dryer having excellent durability can be provided.
If the substrate glass 62 has a thermal expansion coefficient of less than 7X 10-6The low-expansion crystallized glass or quartz glass of (2) can further reliably prevent heat from accumulating in the substrate glass 62 and rapidly expanding and breaking. The upper limit of the thermal expansion coefficient of the crystallized glass or the quartz glass forming the substrate glass 62 is set to 7 × 10-6Is based on the following verification results. In the verification, the thermal expansion coefficient is 7.6 multiplied by 10-6The white plate glass of (1), a glass substrate comprising the white plate glass and a multilayer TiO film laminated on one surface of the glass substrate2/SiO2、Nb2O5/SiO2The optical filter for comparison of formation of a multilayer film formed by the above method was verified under the same conditionsThe optical filter for comparison and the optical filter 60 in which the substrate glass 62 is formed of the above-mentioned crystallized glass or quartz glass have thermal characteristics. The result of the verification is: the substrate glass 62 has a thermal expansion coefficient of less than 7X 10-6In the case of the optical filter 60 made of the low-expansion crystallized glass or the quartz glass of (2), no change in appearance was observed, but in the case of the optical filter for comparison, breakage due to heating was observed. Based on the above verification results, the upper limit of the coefficient of thermal expansion of the crystallized glass or the quartz glass forming the substrate glass 62 was set to 7 × 10-6。
When the optical filter 60 is composed of the substrate glass 62 and the multilayer film 71 laminated on one surface of the substrate glass 62, and the substrate glass 62 is formed of low-expansion quartz glass or transparent crystallized glass, the transmittance of infrared light can be improved as compared with the case where the substrate glass 62 of the optical filter 60 is formed of black crystallized glass. Therefore, the amount of heat transferred from the dryer can be increased to a high degree corresponding to the high transmittance of infrared light, and heating and drying of hair, drying of a human body, or the like can be effectively performed. In addition, since the optical filter 60 configured by the substrate glass 62 made of low-expansion quartz glass or transparent crystallized glass and the multilayer film 71 blocks visible light by the reflection action of the multilayer film 71, the substrate glass 62 hardly absorbs light such as visible light, and therefore, has the following advantages: since there is no accumulation of heat associated with light absorption, it is possible to more reliably prevent the optical filter 60 from being damaged by heat. The visible light reflected by the multilayer film 71 also plays a role of promoting the temperature increase of the filament of the bulb 38 of the light-emitting body 4, and is advantageous in that the power consumption of the filament can be reduced to save power. Further, by changing the laminated structure of the multilayer film 71 and the physical properties of the laminated film in various ways, the cutoff wavelength of visible light can be changed to transmit a part of visible light, and thus the color of light sent from the dryer can be red, white, or the like.
When the substrate glass 62 is formed of low-expansion quartz glass or transparent crystallized glass, and the optical filter 60 is configured by the substrate glass 62 and the multilayer film 71 laminated on one surface of the substrate glass 62, the optical filter 60 is disposed in a state where the multilayer film 71 is positioned on the emission surface side of the substrate glass 62. This is because the incident surface side of the substrate glass 62 becomes higher in temperature than the emission surface side, and the substrate glass 62 and the multilayer film 71 can be prevented from being overheated by disposing the optical filter 60 in a state where the multilayer film 71 is positioned on the emission surface side of the substrate glass 62. When the optical filter 60 is disposed with the multilayer film 71 on the incident surface side, the multilayer film 71 may be heated to change its properties, thereby impairing the visible light reflection function.
In the case where the substrate glass 62 is formed of black crystallized glass in which β -quartz solid solution crystals are precipitated in glass, the optical filter 60 can prevent visible light from transmitting by absorbing visible light by the solid solution crystals, and the temperature of the optical filter 60 is easily increased by the heat absorption action and the heat radiation action of the solid solution crystals, and therefore, by sending the drying air sent from the air sending fan 3 to the periphery of the optical filter 60, the temperature of the drying air can be increased, and heating and drying of hair, drying of human body, and the like can be efficiently performed.
When a plurality of optical filters 60 are disposed adjacent to each other with a gap E in the light radiation path between the reflecting mirror 10 and the blowing port 9, a part of the dry air sent along the periphery of the reflecting mirror 10 can be introduced into the gap E, and the optical filters 60 can be forcibly cooled by the dry air. According to such a dryer, even when the dryer is continuously used, it is possible to reliably prevent the optical filter 60 from being damaged due to an overheated state. Further, by introducing a part of the drying air into the gap E before the drying air is introduced, the chance of contact between the drying air and each optical filter 60 can be increased, and the temperature of the drying air can be raised.
The filter structure 11 is constituted by the optical filter 60 and the light transmitting body 61 disposed on the light radiation path between the optical filter 60 and the outlet 9. Further, the light-transmitting body 61 is formed of a light-transmitting material that allows infrared light to pass therethrough. According to such a dryer, since the light-transmitting body 61 can prevent fingers and foreign matter entering from the air outlet 9 into the air guide portion 7 from coming into contact with the optical filter 60, even if fingertips enter the inside of the air outlet 9 by mistake, a dryer excellent in safety can be obtained in which fingertips are not burned by coming into contact with the optical filter 60.

(embodiment 1) fig. 1 to 4 show an embodiment 1 in which a dryer according to the present invention is applied to a blower. The front-back, left-right, up-down in the present embodiment are indicated by the intersecting arrows shown in fig. 2, and the front-back, left-right, up-down marks marked in the vicinity of the respective arrows. In fig. 2 and 3, a blower is configured by accommodating an axial-flow blower fan 3 rotationally driven by a fan motor 2, a halogen lamp (light emitting body) 4 serving as a heat source, and the like in a front-rear long main body casing 1 also serving as a handle. The main body casing 1 includes a cylindrical air guide portion 7 formed by joining a pair of upper and lower half-divided bodies 5 and 6 formed in a groove shape, an air inlet 8 is formed at the rear end of the air guide portion 7, and an air outlet 9 is formed at the front end.
The blower fan 3 is disposed in the rear half of the main body casing 1, and pressurizes air taken in from the inlet 8 and sends the air toward the outlet 9. The halogen lamp 4 is disposed in the front half of the main body casing 1, and a reflector 10 that reflects and guides light emitted from the halogen lamp 4 toward the outlet 9 is fixed around the halogen lamp 4. A filter structure 11 is disposed on a light radiation path between the reflecting mirror 10 and the outlet 9. The outlet 9 also serves as an outlet for dry air and an irradiation port for irradiating infrared rays (heat rays) emitted from the halogen lamp 4 to the hair of the user.
The touch sensor 12, which is touched by a human body to be detected, covers most of the peripheral surface of the main body casing 1, and the operation knob 15 of the power switch 14 is disposed near the operation portion formed on the upper portion of the touch sensor 12. When the operation knob 15 is slid back and forth along the surface of the main body case 1, the power switch 14 can be switched between the on state and the off state. As shown in fig. 3, the power switch 14 is accommodated in an accommodating recess 17 formed in an upper portion of the main body case 1, and a control board 19 is accommodated in an accommodating recess 18 formed in a lower portion of the main body case 1, and the control board 19 controls a driving state of the fan motor 2 and the halogen lamp 4.
A suction grill 22 is attached to the suction port 8 of the main body casing 1, and a socket 25 for detachably connecting a power supply plug 24 is provided at the center of the suction grill 22. A blowout grill 23 made of a metal material such as aluminum is attached to the blowout port 9 of the main body casing 1. The blowing grille 23 integrally includes a cylindrical outer cylinder 26, an inner cylinder 27, and a plurality of flow control fins 28 radially connecting the two cylinders 26, 27.
As shown in fig. 3, the fan motor 2 and the blower fan 3 are supported by a fan housing 29. The fan case 29 integrally includes a cylindrical outer cylinder 30 surrounding the periphery of the blower fan 3, a bracket portion 31 for attaching the rear end portion of the fan motor 2, a cylindrical inner cylinder 32 surrounding the bracket portion 31, and a plurality of flow control fins 33 radially connecting the outer cylinder 30 and the inner cylinder 32. A flange 34 is formed at the front end of the outer cylinder 30 so as to protrude outward, and the fan case 29 is fixed to the main body case 1 by engaging and holding the flange 34 by an engaging groove 35 formed on the inner surface of the half bodies 5 and 6.
The halogen lamp 4 is configured by connecting a bulb 38 in which a filament, an inert gas, a halogen gas, and the like are sealed, to the front and rear of an outer case 39. When the halogen lamp 4 is turned on, visible light and infrared light are emitted from the bulb 38. A reflector 10 for condensing light is disposed around the bulb 38. The reflecting mirror 10 is formed in a round cylindrical shape that is open toward the outlet 9, using a metal such as aluminum as a raw material, and has a reflecting film formed on the inner surface thereof. An insertion hole 43 for allowing the bulb 38 to be adjacent to the inside of the reflector 10 is formed at the rear center of the reflector 10. An annular flange 44 (see fig. 1) for reinforcing the front edge is formed on the outer peripheral surface of the front edge (opening peripheral edge) of the reflector 10 so as to protrude outward. Engaging recesses 45 are formed in four places, i.e., the upper, lower, left, and right, on the outer peripheral surface of the flange 44, and the mirror 10 can be supported in a stable posture by engaging the support frame 47 with the engaging recesses 45.
The support frame 47 is formed by combining a pair of mica plates 48 and 49 in an orthogonal manner (see fig. 1 and 4), and the reflector 10 and the housing 39 of the halogen lamp 4 are supported by the support frame 47. The support frame 47 also serves as a flow rectifier for the air generated by the blower fan 3, and supports the front half of the fan motor 2 from four sides (up, down, left, and right). The rear end portions of the mica boards 48 and 49 are inserted into and engaged with a slit 50 provided at the front end portion of the fan housing 29 (see fig. 3), thereby restricting the rotation of the support frame 47 with respect to the main body housing 1. A shallow mounting groove 57 is recessed in a circumferential shape in the inner surface of the front end portion of the main body casing 1, and the outer cylinder 26 of the outlet grill 23 is fitted into the mounting groove 57, whereby the offset movement of the outlet grill 23 with respect to the main body casing 1 in the front-rear direction (axial direction) and the radial direction is restricted.
In fig. 1, the filter structure 11 is composed of 2 optical filters 60 disposed on the light radiation path between the reflecting mirror 10 and the outlet 9, and a light transmitting body 61 disposed on the light radiation path between the front optical filter 60 and the outlet 9. The optical filter 60 is composed of a disk-shaped substrate glass 62 and an annular holder 63 for supporting the substrate glass 62, and the substrate glass 62 is made of low-expansion glass. The substrate glass 62 is preferably made of a material having a thermal expansion coefficient of less than 7X 10-6In this example, the crystal is formed of a black crystallized glass (crystallized glass) in which β -quartz solid solution crystals are precipitated in the glassThe substrate glass 62 was formed, and 2 optical filters 60 were adjacent to each other with a gap E therebetween. The black crystallized glass had a thermal expansion coefficient of 7X 10-7The transmittance of light (electromagnetic wave) having a wavelength of 600nm or less in the visible light region is 50% or less. The gap E is preferably 2mm or more, and in this embodiment, the gap E is set to 10 mm.
As described above, if the substrate glass 62 has a thermal expansion coefficient of less than 7X 10-6The black crystallized glass absorbs visible light by β -quartz solid solution crystals precipitated in the glass, and therefore the amount of visible light absorbed by the substrate glass 62 increases as the thickness thereof increases, in this example, the thickness of the substrate glass 62 is set to 3mm so that most of visible light can be absorbed in cooperation by the optical filters 60 before and after the substrate glass 62, the thickness of the substrate glass 62 is preferably selected within the range of 0.8 to 6mm, if the thickness of the substrate glass 62 is less than 0.8mm, the strength of the substrate glass 62 is insufficient, and there is a problem in durability, and therefore, for example, the substrate glass 62 is broken when a drop impact is applied, and if the thickness of the substrate glass 62 exceeds 6mm, the weight of the optical filter 60 increases, and the substrate glass is heavy when a blower is used, and the ease of use is poor.
Gaps E1 and E2 similar to the above-described gap E are provided between the rear optical filter 60 and the reflector 10 and between the front optical filter 60 and the light-transmitting body 61. The gaps E1 and E2 are preferably 0.5mm or more, and in this embodiment, the gap E1 is 1mm and the gap E2 is 10 mm. Electromagnetic waves (visible light and infrared light) having wavelengths of 400 to 3000nm are emitted from the halogen lamp 4, but as described above, visible light having a wavelength of 600nm or less among the emitted light of the halogen lamp 4 is absorbed while passing through the two optical filters 60. As described above, when 2 optical filters 60 absorb visible light, the degree of absorption of visible light by the filter structure 11 can be significantly increased as compared with the case where only 1 optical filter 60 absorbs visible light. Therefore, when the hair dryer is used, it is possible to reliably prevent visible light from being emitted from the outlet 9 of the dryer, and it is possible to eliminate dazzling light from entering the eyes of the user when the hair is dried, and it is possible to smoothly perform the hair styling operation without feeling dazzling.
As described above, by disposing the optical filters 60 adjacent to each other with the gap E therebetween and by providing the gaps E1 and E2 between the optical filter 60 and the reflector 10 and between the optical filter 60 and the light-transmitting body 61, a part of the drying air sent along the periphery of the reflector 10 is introduced into the gaps E, E1 and E2, whereby the substrate glass 62 and the light-transmitting body 61 can be reliably prevented from falling into an overheated state, the chance of contact between the drying air and each optical filter 60 is increased, and the temperature of the drying air can be increased. Incidentally, when two optical filters 60 are disposed adjacent to each other without a gap, heat is likely to accumulate on the adjacent surface of the substrate glass 62 and fall into an overheated state, and it is difficult to exhibit sufficient thermal shock resistance.
The light-transmitting body 61 is composed of a disk-shaped substrate glass 64 and an annular holder 65 that supports the substrate glass 64, and the substrate glass 64 is formed of a transparent glass material (light-transmitting material) that allows infrared light to pass therethrough. The holder 63 of the optical filter 60 and the holder 65 of the light transmitting body 61 are each made of a metal material such as aluminum, and are formed as a ring having a diameter larger than the circumferential surface of the mirror 10, and engaging recesses 66, 67 are formed at four positions on the circumferential surfaces of the holders 63, 65. The mica boards 48 and 49 are formed with holding recesses 68 and 69 that engage with the holders 63 and 65, and the optical filter 60 and the light transmitting body 61 are fixedly held by the support frame 47 so as not to be movable in all directions by the engagement of the engaging recesses 66 and 67 with the recessed walls of the holding recesses 68 and 69. The front surface of the holder 65 of the light transmitting body 61 is received by the inner cylinder 27 of the previous blow-out grill 23. By disposing the light-transmitting body 61 behind the outlet grill 23 in this manner, the infrared light that has passed through the optical filter 60 can be transmitted, and the light-transmitting body 61 can prevent fingers and foreign matter that enter the air guide portion 7 from the outlet 9 from coming into contact with the optical filter 60. Therefore, the finger tip can be reliably prevented from erroneously coming into contact with the optical filter 60, and the safety of the hair dryer can be improved.
The control unit mounted on the control board 19 controls the drive current supplied to the halogen lamp 4 and the fan motor 2 in accordance with the states of the power switch 14 and the touch sensor 12. For example, when the power switch 14 is in an on state and a finger is in a detection state of the touch sensor 12, the control unit supplies a drive current to the halogen lamp 4 and the fan motor 2. When the power switch 14 is switched to the off state or the touch sensor 12 is in the non-detection state in which no human body is detected, the control unit stops supplying the drive current to the halogen lamp 4 and the fan motor 2.
However, even if the power switch 14 is switched from the off state to the on state in the non-detection state of the touch sensor 12, and then the touch sensor 12 becomes the detection state, the control section does not supply the drive current to the halogen lamp 4 and the fan motor 2. This is because, for example, if a user who does not notice that the power switch 14 is turned on holds the main body casing 1 to move the hair dryer, the touch sensor 12 is in the detection state, but in this case, the halogen lamp 4 is turned on against the user's intention to start the fan motor 2, which is a surprise to the user.
In the blower of example 1 configured as described above, the substrate glass 62 of the optical filter 60 of the filter structure 11 is formed of low-expansion glass having excellent heat resistance and strength and excellent thermal shock resistance. Further, a part of the drying air sent along the periphery of the reflecting mirror 10 is introduced into the gap E and the gaps E1 and E2 before and after the filter structure 11, and the optical filter 60 and the light transmitting body 61 can be forcibly cooled by the drying air. According to such a blower, even when the blower is continuously used, it is possible to reliably prevent the optical filter 60 and the light-transmitting body 61 from being damaged due to being overheated. Further, even if the fingertips enter the inside of the outlet 9 by mistake, the fingertips can be prevented from touching the high-temperature optical filter 60 by the light-transmitting body 61, and therefore, a hair dryer that is not burned by the user and that is excellent in durability and safety as a whole can be provided. Further, by introducing a part of the drying air into the gaps E, E1 and E2, the chance of contact between the drying air and each optical filter 60 can be increased, and the temperature of the drying air can be increased, so that the hair can be heated, dried, and the like efficiently in a short time.
(embodiment 2) fig. 5 shows a dryer according to an embodiment 2 of the present invention in which a part of a filter structure 11 is modified. In example 2, a filter structure 11 is configured by 1 optical filter 60 disposed in the light radiation path between the reflecting mirror 10 and the outlet 9, and a light transmitting body 61 disposed in the light radiation path between the optical filter 60 and the outlet 9, which is different from the filter structure 11 of example 1. The optical filter 60 is basically the same in structure as the optical filter 60 of example 1, but is different from the optical filter 60 of example 1 in that the substrate glass 62 is 6mm thick. Gaps E1 and E2 are provided between the optical filter 60 and the reflector 10 and between the optical filter 60 and the light-transmitting body 61. Since the other configurations are the same as those in embodiment 1, the same components are denoted by the same reference numerals and their descriptions are omitted. The same applies to the following examples.
As described above, if the filter structure 11 is configured by 1 optical filter 60 and the light transmitting body 61, it is possible to provide a small-sized hair dryer which can simplify the filter structure 11 by reducing the number of components, and can reduce the interval between the reflecting mirror 10 and the blowing port 9, and accordingly, can reduce the front-rear length of the main body casing 1. Further, since the substrate glass 62 is formed of black crystallized glass having a thickness of 6mm, visible light can be absorbed to the same extent as the filter structure 11 of example 1, even though the structure is one optical filter 60 for absorbing visible light.
(embodiment 3) fig. 6 shows an embodiment 3 in which a part of the filter structure 11 is modified. In example 3, the thermal expansion coefficient was less than 7X 10-6The substrate glass 62 is made of low-expansion quartz glass, and a plurality of layers of TiO are laminated on one surface of the substrate glass 622/SiO2、Nb2O5/SiO2And the like to form the multilayer film 71. The multilayer film 71 transmits infrared light but reflects visible light. The substrate glass 62 was set to have a thickness of 3mm, and was disposed in a state where the multilayer film 71 was positioned on the emission surface side. This is because the incident surface side of the substrate glass 62 is at a higher temperature than the emission surface side, and the multilayer film 7 is usedThe optical filter 60 is disposed in a state where 1 is positioned on the emission surface side of the substrate glass 62, and the substrate glass 62 and the multilayer film 71 can be prevented from being overheated. As described above, in the case of the optical filter 60 in which the multilayer film 71 is formed on one surface, it is preferable that the multilayer film 71 is disposed in a state of being positioned on the emission surface side. When the optical filter 60 is disposed with the multilayer film 71 on the incident surface side, the multilayer film 71 may be heated to change its properties, and the reflection of visible light may be impaired. However, the optical filter 60 may be disposed in a state where the multilayer film 71 is positioned on the incident surface side, depending on the distance from the halogen lamp 4, the arrangement of the optical filter 60, and the like. Further, instead of the low-expansion silica glass, the thermal expansion coefficient may be less than 7X 10-6The substrate glass 62 is formed of the low-expansion transparent crystallized glass of (1), and in this case, the substrate glass 62 may have a transmittance of 50% or more for light (electromagnetic wave) having a wavelength of 600nm or less.
As described above, when the optical filter 60 is composed of the substrate glass 62 and the multilayer film 71 laminated on one surface of the substrate glass 62, and the substrate glass 62 is formed of low-expansion quartz glass or transparent crystallized glass, the transmittance of infrared light can be improved as compared with the case where the substrate glass 62 of the optical filter 60 is formed of black crystallized glass. Therefore, the amount of heat transferred from the dryer can be increased to a high degree corresponding to the transmittance of infrared light, and heating and drying of hair, drying of human body, and the like can be efficiently performed, and the optical filter 60 having excellent heat resistance and strength as a whole and excellent thermal shock resistance can be obtained. Further, since the optical filter 60 configured by the substrate glass 62 made of low-expansion quartz glass or transparent crystallized glass and the multilayer film 71 blocks visible light by the reflection action of the multilayer film 71, light such as visible light is hardly absorbed, and therefore, there is no accumulation of heat associated with light absorption, and therefore, breakage of the optical filter 60 due to heat can be more reliably prevented. The visible light reflected by the multilayer film 71 also plays a role of promoting the temperature increase of the filament of the bulb 38, and is advantageous in that the power consumption of the filament can be reduced to save power. Further, by changing the laminated structure of the multilayer film 71 and the physical properties of the laminated film in various ways, the cutoff wavelength of visible light can be changed to transmit a part of visible light, and thus the color of light sent from the dryer can be red, white, or the like.
(embodiment 4) fig. 7 shows an embodiment 4 in which a part of the filter structure 11 is modified. In example 4, the filter structure 11 was constituted by 1 optical filter 60 and the light-transmitting body 61, similarly to the filter structure 11 of example 2, but it is different from the optical filter 60 of example 2 in that the thickness of the substrate glass 62 was 3 mm.
As described above, if the filter structure 11 is configured by 1 optical filter 60 and the light transmitting body 61, the filter structure 11 can be simplified by the number of components being reduced, and the distance between the reflecting mirror 10 and the air outlet 9 can be further reduced as compared with the filter structure 11 of example 2, and accordingly, the front-rear length of the main body casing 1 can be reduced, and the hair dryer can be further downsized.
(embodiment 5) fig. 8 shows an embodiment 5 in which a part of the filter structure 11 is modified. In example 5, the filter structure 11 is configured by 1 optical filter 60 disposed on the rear surface of the blowout grill 23. The substrate glass 62 of the optical filter 60 has a thermal expansion coefficient of less than 7 × 10, similarly to the substrate glass 62 of example 3-6A plurality of layers of TiO laminated on one surface of the substrate glass 622/SiO2、Nb2O5/SiO2And the like to form the multilayer film 71. Such a filter structure 11 can minimize the number of components, simplify the filter structure 11, and further reduce the manufacturing cost thereof. The substrate glass 62 in this example may have a thermal expansion coefficient of less than 7 × 10, similarly to the substrate glass 62 in example 3-6The low-expansion transparent crystallized glass of (2).
In each of the above embodiments, the light emitter 4 may be configured by an incandescent lamp, a xenon lamp, a metal halide lamp, or the like, in addition to the halogen lamp. In this case, the power switch 14 can be switched between a cool air mode in which only the blower fan 3 is driven, a low-temperature weak air mode in which the blower fan 3 and the light emitting body 4 are simultaneously driven, and a high-temperature strong air mode in which the temperature is higher than that in the weak air mode and the air volume is large. The main body case 1 may be formed in an elliptical cylindrical shape, a polygonal cylindrical shape, or the like, in addition to the cylindrical shape, and a foldable handle may be provided on the lower surface side of the main body case 1 as needed. The present invention is not limited to dryers for humans, and can be applied to dryers for animals such as dogs and cats.
