Description
- The present invention relates to a dryer used for drying the hair on a person's head.
- Dryers used for drying the hair on a person's head typically have a structure in which a blower and a heater are accommodated in a casing having an outlet, and the blower draws air through an inlet formed in the casing, and blows the air toward the outlet. The air blown toward the outlet is heated by the heater to generate hot air at the outlet, and a user applies the hot air to the hair for a certain time period, to dry the hair.
- PTL 1: JP6-335407A
- However, when hair is dried by using the above-described dryer, a problem arises in that the hair near the outlet may be excessively dried and damaged.
- Therefore, an objective of the present invention is to provide a dryer that can prevent hair from being excessively dried.
- The dryer of the present invention has been developed to solve the aforementioned problem. The dryer of the present invention includes: a casing having an inlet through which air is drawn from the outside, and an outlet through which air is blown to the outside; a blower, provided in the casing, for drawing air through the inlet and blowing the air toward the outlet; a heater, provided in the casing, for heating air blown toward the outlet; a steam generator, provided outside the casing, for generating steam; a steam-heating means, provided in the casing and connected to the steam generator through a connection pipe, for heating steam supplied through the connection pipe; and a steam duct through which steam heated by the steam-heating means is caused to flow toward the outlet.
- The dryer is structured so that steam generated by the steam generator is discharged from the outlet through the steam duct together with hot air generated by the blower and the heater. Therefore, the hair can be dried while being moisturized, thereby preventing the hair from being excessively dried. Thus, damage to the hair can be prevented, and, furthermore, the generation of static electricity in the hair can be reduced. Also, in the dryer, the steam-heating means for heating steam supplied through the connection pipe is provided in the casing. Therefore, even when steam that has passed through the connection pipe contains water droplets, the droplets can be evaporated by the steam-heating means, thereby preventing droplets from being discharged through the outlet.
- Further, the steam dryer may further include a flow rate adjustment portion, provided in the connection pipe, for adjusting the flow rate of steam flowing through the connection pipe. “Provided in the connection pipe” can mean not only provided in the mid-portion of the connection pipe, but also provided at the end portion of the connection pipe, for example, in a portion between the steam generator and the connection pipe.
- Further, in the dryer, a steam path through which steam flows from the connection pipe toward the steam duct, is formed in the steam-heating means, and the steam path has a closed path portion extending along a steam flowing direction and having a dead end. In this structure, when water droplets are contained in steam passing through the connection pipe, the droplets enter the closed path portion, and can be stored in the steam-heating means for an increased time period. Therefore, the water droplets can be reliably evaporated.
- Further, in the dryer, the connection pipe may have an electrically heated wire wound around a connection pipe body. In this structure, steam generated by the steam generator can be supplied to the steam-heating means while being heated in the connection pipe. Therefore, a portion of the steam can be prevented from becoming water droplets due to the steam being cooled in the connection pipe.
- According to the present invention, hair can be prevented from being excessively dried.

switch 27 opens the steamelectromagnetic valve 11, and supplies steam through theconnection pipe 8, the inside of which is heated to 120° C. to 150° C., from thesteam generator 9 to the steam-heating means 6. The steam that has reached the steam-heating means 6 enters thesteam path 62 through theentrance 621, and flows toward theexit 622 while being heated by thesecond heaters steam generator 9 is condensed before reaching the steam-heating means 6, and steam supplied through theconnection pipe 8 may contain water droplets W. The water droplets W contained in the steam reach the divergingportions 623 of thesteam path 62, and thereafter flow into theclosed path portions 624, and are heated and evaporated in the closed path portions 624 (FIG. 3 ). As described above, even when steam supplied through theconnection pipe 8 contains water droplets, the droplets are evaporated into steam while flowing through thesteam path 62. Therefore, only steam is blown through theexit 622 of the steam-heating means 6. The steam flows through thesteam duct 7 and is blown through theoutlet 22 together with hot air. - Thus, hot air and steam blown through the
outlet 22 are applied to the hair, and the hair is dried while being appropriately moisturized. When the hair is sufficiently dried, theblower switch 25 and theheater switch 26 are each turned off, to stop operating theblower 3 and the first heater 4 (FIG. 1 ). Further, the steamingswitch 27 is turned off to close the steamelectromagnetic valve 11 and stop the ejection of steam. - During use with the
heater switch 26 turned on as described above, hot air is blown through theoutlet 22. When theheater switch 26 is turned off and theblower switch 25 is set to “High” or “Low,” air blown toward theoutlet 22 by theblower 3 is not heated, and cool air is blown through theoutlet 22. - As described above, the
dryer 1 of the present embodiment allows steam generated by thesteam generator 9 to be blown through theoutlet 22 together with hot air generated by theblower 3 and the first heater 4. Thus, excessive drying and damage of the hair can be prevented. Further, the generation of static electricity in the hair can be reduced. Further yet, in thedryer 1, even when steam supplied through theconnection pipe 8 contains water droplets, the droplets can be reliably evaporated by the steam-heating means 6, and droplets can be prevented from falling onto the hair. - While the embodiment of the present invention has been described above, the present invention is not limited thereto, and various modifications can be made without departing from the gist of the invention. For example, in the embodiment described above, in the steam-heating means 6, the
steam path 62 having closedpath portions 624 is formed. However, the present invention is not limited thereto as long as water droplets contained in steam can be evaporated by the steam-heating means 6, and thesteam path 62 may not have the closedpath portions 624 formed therein. - Further, in the embodiment described above, the
connection pipe 8 is a heating hose having an electrically heated wire wound around the connection pipe body. However, when steam generated by thesteam generator 9 can be supplied to the steam-heating means 6, a member having no electrically heated wire, such as a TEFLON (registered trademark) hose, a member formed by silicone, or a member that can be freely bent and has excellent heat resistance, steam resistance, and pressure resistance, can be used as theconnection pipe 8. - Further yet, in the
dryer 1 of the embodiment described above, the first heater 4 can be turned on or off by using theheater switch 26 so that cool air can be generated. However, for example, the first heater 4 may be operated in conjunction with theblower 3 to generate only hot air. -
