Technical Field

[0001] The present invention relates to a hair drying machine. Background Art

[0002] Hair dryers are widely used that include a fan and a heater and send warm air to the hair to dry the hair.

[0003] For example, Japanese Patent Publication No. 2022-515494 discloses a hair dryer in which a fan and a heater are arranged on a handle held by a user. Summary of the invention

[0004] However, in the above-mentioned prior art, since the fan and the heater are arranged in series in the handle, the handle becomes long, and a head for guiding air in the direction of drying the hair is arranged in front of the handle. Therefore, the hair dryer becomes large-scale.

[0005] An object of one aspect of the present invention is to achieve miniaturization of a hair dryer.

[0006] In order to solve the above-mentioned problems, the hair dryer of the present invention is constituted to include: a first shell, which forms an air path extending in a first direction; a second shell, which has an internal space connected to the downstream side of the air path; a heater, which is located in the air path to the internal space; and a partition wall portion, which is arranged around the heater in a manner extending the air path, and a plurality of first blowing outlets connected to the internal space are provided in a plurality of first areas in the internal space sandwiching the partition wall portion.

[0007] According to one aspect of the present invention, it is possible to reduce the size of the hair dryer. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] [Implementation Method] (Hair dryer) In the present disclosure, a hair dryer that can easily dry hair is realized. First, the hair dryer of the present disclosure is described. In the present disclosure, "hair dryer" refers to the entire machine that can dry hair using gas. Therefore, the hair dryer also includes a dryer that can dry other items (such as pet hair) together with hair, an air supply dryer that can be used for purposes other than drying hair, or a handheld dryer.

[0010] Hair dryers include devices that can dry hair and deliver air to the skin for skin care. The temperature of the air supplied by the hair dryer is not particularly limited. The hair dryer can supply at least one of warm air and cold air, for example.

[0011] Here, "cold air" is not defined by absolute temperature, but is air supplied without substantially heating the supplied gas by heating means such as a heater. In contrast, "warm air" refers to air supplied by heating the supplied gas by heating means such as a heater.

[0012] In addition, the type of gas is not particularly limited. Examples of preferred gases include air, nitrogen, oxygen, argon, and carbon dioxide. These gases are preferably gases in the temperature range in which the hair dryer is used.

[0013] (Overview of the hair dryer 1) Hereinafter, one embodiment of the present invention will be described in detail. Figure 1 It is a front view which shows the appearance of the hair dryer 1 which concerns on this embodiment. Figure 2 yes Figure 1 AA cross-sectional view of the hair dryer 1 in FIG.

[0014] like Figure 1 As shown, the hair dryer 1 includes: a substantially cylindrical first body (first housing) 10 held by a user; and a substantially cylindrical second body (second housing) 20 connected to one end of the first body 10. The shape of the first body 10 is not limited to a substantially cylindrical shape, and may be a columnar shape, a polygonal columnar shape, or a polygonal columnar shape with rounded corners. Similarly, the shape of the second body 20 is not limited to a substantially cylindrical shape, and may be a columnar shape, a polygonal columnar shape, or a polygonal columnar shape with rounded corners.

[0015] In addition, in the drawings, the direction in which the first body 10 extends is marked as a Z direction, the direction perpendicular to the Z direction is marked as an X direction, and the direction perpendicular to the X direction and the Z direction is marked as a Y direction.

[0016] The first body 10 is shaped to extend in one direction (Z direction in the figure) and has a grip portion 14 for a user to grip. An operation portion 60 composed of a plurality of switches is provided on the first body 10. In addition, one end of the first body 10 is connected to the second body, and the other end of the first body 10 is connected to a power cable 80.

[0017] An air inlet 13 is disposed between the power cable 80 and the grip 14 of the first body 10. The cross-sectional shape of the air inlet 13 may be, for example, an elongated shape or a dot shape.

[0018] The second body 20 is shaped to extend in a direction (in the Y direction in the figure) substantially orthogonal to one direction in which the first body 10 extends, and one end of the second body 20 is closed. In contrast, a blowout portion 25 is disposed at the other end of the second body 20. The blowout portion 25 is provided with a plurality of blowout ports 21. In addition, the gas passes through the blowout portion 25 from the air intake port 13 via the first body 10 and the second body 20. In addition, the blowout portion 25 is provided with a distance sensor 23 for measuring the distance to the object to be dried.

[0019] The distance sensor 23 is, for example, a TOF (Time Of Flight) sensor, and may have a light emitting unit and a light receiving unit composed of semiconductor lasers. However, the distance sensor 23 is not limited to the TOF sensor, and may be other types. The distance sensor 23 measures the distance from the position where the distance sensor 23 is set to the object (at least a part of the human body (for example, scalp or hair, etc.) or a part) in front of the distance sensor 23. When the hair is dried by the hair dryer 1, the distance sensor 23 measures the distance to the hair. In addition, the distance sensor 23 may not be provided.

[0020] like Figure 2 As shown in FIG. 1 , the hair dryer 1 is provided with at least one ion generating unit 24 for supplying ions to the air to be blown and a cylindrical member 40 therein. The ion generating unit 24 is provided on the back side of the blower 25 and has an electrode 24A protruding into the hollow portion (internal space 22 described later) inside the second body 20. In addition, the second body 20 has a hole 27 (see FIG. 27 ) for cleaning the electrode 24A of the ion generating unit 24 in a region facing the electrode 24A of the ion generating unit 24. Figure 5 ).

[0021] in addition, Figure 2 The figure numeral 22 shows the general shape of the internal space with a single-dot chain line. Figure 2 In the cross-sectional view, the overall shape of the internal space is roughly shown, including the space portion that is not originally shown.

[0022] The ion generating unit 24 is a unit that generates ions. The ion generating unit 24 can generate at least one of negative ions and positive ions, or both. For example, the ion generating unit 24 may include a needle-shaped discharge electrode and a ring-shaped induction electrode surrounding the discharge electrode as the electrode 24A. In this case, a voltage may be applied between the discharge electrode and the induction electrode to generate corona discharge, and H2O2 may be generated around the discharge electrode. + (H2O)m and other positive ions and O 2- The generated positive ions and negative ions are discharged together with the air blown out from the blower outlet 21. The ion generating unit 24 is not essential and may not be provided.

[0023] The ion generating unit 24 of one embodiment of the present invention is an example of a charged particle supply (generation) mechanism. The charged particle supply (generation) mechanism is a mechanism that supplies (generates) charged particles.

[0024] Charged particles refer to electrically non-neutral particles and active species activated in an electrically non-neutral state. Charged particles are not limited to particles with electric charge, and include particles such as atoms and molecules that have unpaired electrons, although they have no electric charge. Specifically, charged particles include, for example, ions with positive or negative charges, complexes of ions with positive or negative charges, free radicals, electrons, protons, and the like.

[0025] The charged particle supply (generation) mechanism may be, for example, a mechanism that supplies (generates) only one type of charged particles, or a mechanism that supplies (generates) multiple types of charged particles. The charged particle supply (generation) mechanism may, for example, supply (generate) both positive ions or complexes of positive ions (for example, complexes of polar molecules such as water molecules coordinated to positive ions) and negative ions or complexes of negative ions (for example, complexes of polar molecules such as water molecules coordinated to negative ions). The charged particle supply (generation) mechanism may, for example, supply (generate) only one of the complexes of positive ions and negative ions.

[0026] The tubular component 40 is a tubular component that is connected from the air passage 12 of the first body 10 to the internal space 22 of the second body 20. The tubular component 40 is formed of a flame retardant material. A heater 41 is inserted into the tubular component 40. In addition, a tubular sheet not shown in the figure is provided between the tubular component 40 and the heater 41, and the tubular sheet is formed with flame retardant mica as the main raw material. In the present embodiment, the lengths of the tubular component 40, the heater 41 and the tubular sheet in the longitudinal direction (Z direction) are substantially the same. In addition, the tubular component 40 and the tubular sheet are preferably longer than the heater 41. In addition, more than half of the total length (total length) of the tubular component 40 and the heater 41 in the longitudinal direction are located in the internal space 22. The front end of the internal space 22 side of the tubular component 40 and the heater 41 is located at a position above the midpoint of the internal space 22 in the Z direction.

[0027] The area inside the first body 10 is referred to as an air passage 12. The air passage 12 may be formed by the position of the fan 11 (electric blower) accommodated in the first body 10, or may be formed by the air intake port 13. The air passage 12 is formed by extending along the first direction (Z direction) 15. In addition, the space formed inside the second body 20 is referred to as an internal space 22. The internal space 22 is connected to the downstream side of the air passage 12.

[0028] The cylindrical member 40 is accommodated in the partition wall portion 28 (see Figure 5 , 6 ) and the first body 10. The partition wall 28 is formed on the second body 20 to match the outer shape of the tubular component 40. That is, the partition wall 28 is formed into a substantially cylindrical shape with openings at both ends, and the wind passes through the openings. In other words, the heater 41 is located in the air path 12 and the internal space 22 via the tubular component 40. In addition, as a result, the partition wall 28 is arranged around the heater 41 on the second body 20 in a manner extending the air path 12. Due to the presence of the tubular component 40, the wind entering from the opening passes through the inside of the tubular component 40, so the wind will not be leaked from the joint between the first body 10 and the second body 20 to deliver air.

[0029] In the hair dryer 1, the fan 11 blows the air sucked from the air inlet 13, heats the air passing through the air path 12 and the heater 41, and blows the warm air or cold air toward the object to be dried from the blow-out port 21. A substrate is disposed inside the first body 10 between the fan 11 and the air inlet 13, and the substrate is cooled by the airflow generated by the rotation of the fan 11.

[0030] Figure 36 is a block diagram showing the configuration of the main parts of the hair dryer 1. The operation unit 60 includes an on / off switch 61, a disposable cold air switch 62, a mode change switch 63, and an air volume change switch 64. When the on / off switch 61 is turned on, power from the power cable 80 is supplied to each part of the hair dryer 1. When the on / off switch 61 is turned off, the power supply to each part of the hair dryer 1 is stopped. In addition, the disposable cold air switch 62 sends a signal notifying that it is operated to the control unit 50 every time it is operated. The control unit 50 alternately controls the heater 41 to be turned on / off every time it receives a signal from the disposable cold air switch 62. In addition, it is also possible to alternately connect and disconnect the power from the power cable 80 to the heater 41 every time the disposable cold air switch 62 is pressed without going through the control unit 50. The mode change switch 63 and the air volume change switch 64 send a signal notifying that they are operated to the control unit 50 every time they are operated. The control unit 50 controls the rotation speed of the fan 11, the heating value of the heater 41, the on / off state of the ion generating unit 24, etc. according to the signals from the mode change switch 63 and the air volume change switch 64. In addition, each switch may be constituted by a button, for example. That is, the control unit 50 controls each part of the hair dryer 1 in a unified manner.

[0031] (Blowout part 25) Figure 4 : This is a front view showing the details of the blow-out section 25. The blow-out section 25 is provided at the downstream front end portion facing the internal space 22, where the wind flowing through the air path 12 is blown out. Three or more blow-out outlets 21 are provided on the blow-out section 25, and the blow-out outlets 21 are connected to the internal space 22. Specifically, in the present embodiment, four blow-out outlets 21 are provided. The centroids of each blow-out outlet 21 on the plane where the blow-out section 25 is arranged are represented by centroids P1 to P4. In addition, the four sides formed by connecting the centroids P1 to P4 with straight lines form a square, and the centroid of the square is set as the centroid C. The plane where the blow-out section 25 is arranged (in the figure, the XY plane) is perpendicular to the flow direction of the gas in the blow-out section 25. In addition, the area in the blow-out section 25 where the blow-out outlet 21 is not present is a closed area where no gas is blown out.

[0032] The outlet 21 opens toward a second direction 21e (Y direction) different from the first direction 15 (Z direction). The angle between the first direction 15 and the second direction 21e may be 90 degrees, but is not limited thereto.

[0033] In order to distinguish the four outlets 21, the outlets 21 corresponding to the centroids P1 to P4 are referred to as outlets 21a to 21d. That is, centroid P1 is located at outlet 21a, centroid P2 is located at outlet 21b, centroid P3 is located at outlet 21c, and centroid P4 is located at outlet 21d.

[0034] (Structure of the internal space 22) Figure 5 yes Figure 2 B--B cross-sectional view of the second body 20 in FIG. Figure 6 yes Figure 2 FIG. 2 is a C--C cross-sectional view of the second body 20 in FIG. An internal space 22 as a hollow portion is formed on the second body 20. The internal space 22 includes a curved surface that produces a smooth curvature change. This is to make the flow of wind change smoothly. In addition, as a result, air can be supplied with less pressure loss.

[0035] The second body 20 includes a wall portion 26 on the extension line of the air passage 12. The wall portion 26 is blown by the wind flowing into the internal space 22 from the air passage 12, and guides the wind in the direction along the wall portion 26. In addition, the wall portion 26 is formed with a peak portion 26a toward the upstream side of the air passage 12, and the wind hitting the wall portion 26 is divided into two directions in the internal space 22 and guided due to the peak portion 26a.

[0036] Furthermore, the wind guided by the wall portion 26 passes through the internal space 22 and is blown out from the blowout port 21. The internal space 22 is formed as a curved surface that curves convexly toward the outside.

[0037] (Relationship between the partition wall 28 and the air outlet 21) As described above, the tubular member 40 is arranged in the partition 28 in the second body 20. In addition, the heater 41 is provided inside the tubular member 40. As a result, in the second body 20, the partition 28 is provided around the heater 41. In addition, the partition 28 may surround the heater 41 on the XY plane in the internal space 22. Here, the XY plane is a plane perpendicular to the first direction 15.

[0038] In the plurality of first regions 28a sandwiching the partition wall 28 in the internal space 22, there are provided the blow-out port 21a (first blow-out port) and the blow-out port 21b (first blow-out port) connected to the internal space 22. In addition, in the second region 28b other than the first region 28a in the internal space 22, there are provided the blow-out port 21c (second blow-out port) and the blow-out port 21d (second blow-out port) connected to the internal space 22.

[0039] The wind from the air passage 12 is divided into two winds by the wall portion 26, one wind reaches the blowout port 21b through the blowout port 21c, and the other wind reaches the blowout port 21a through the blowout port 21d. Then, the wind flowing through the internal space 22 is blown out from the blowout ports 21a to d. In addition, the wind passing through the blowout ports 21a to d only needs to pass through the areas where the blowout ports 21a to d are located. In addition, since there are four blowout ports 21, a sufficient amount of wind for drying hair can be obtained.

[0040] The positional relationship between the partition wall 28 and the blow-out port 21 can shorten the total length (total length) of the hair dryer 1 in the longitudinal direction, i.e., the Z direction. In other words, the distance between the front end of the heater 41 on the inner space 22 side in the longitudinal direction and the peak 26a is shorter than the distance between the front end of the heater 41 on the inner space 22 side in the longitudinal direction and the joint between the first body 10 and the second body 20. In this way, by inserting the heater 41 deep into the inner space 22, the total length (total length) of the hair dryer 1 in the longitudinal direction, i.e., the Z direction, can be shortened. In other words, the hair dryer 1 can be miniaturized.

[0041] Therefore, it is easy to make the position and posture of the second body 20 a state desired by the user, and the hair can be dried effectively. In addition, the space required for the fan 11 and the heater 41, etc., can be accommodated in the inside of the first body 10 held by the user, so that the second body 20 can be easily arranged. Therefore, it is easy to dry the hair.

[0042] Here, it is assumed that in a hair dryer in which a fan and a heater are arranged in series in a handle as in the prior art, the hair dryer is enlarged. Therefore, the head is located at a position separated from the handle held by the user, and it becomes difficult to move the head around the hair. Therefore, in the hair dryer 1 involved in this embodiment, it is easier to dry hair than in the prior art.

[0043] 〔Summarize〕 A hair dryer according to a first aspect of the present invention includes: a first housing having an air passage extending in a first direction; a second housing having an inner space connected to the downstream side of the air path; a heater located in the air path to the inner space; and a partition wall provided around the heater in the second housing so as to extend the air path, A plurality of first air outlets connected to the internal space are provided in the plurality of first regions sandwiching the partition wall portion in the internal space.

[0044] According to the above-mentioned structure, a hair dryer with a low height can be realized, the second housing can be easily moved, and a hair dryer that can easily dry hair can be realized.

[0045] A hair dryer according to a second aspect of the present invention may be configured such that, in the first aspect, a second blow-out port connected to the internal space is provided in a second area of ​​the internal space other than the first area.

[0046] According to the above-mentioned structure, even if the hair dryer is short in height, a sufficient air volume can be obtained through the first air outlet and the second air outlet.

[0047] A hair dryer according to a third aspect of the present invention may be configured such that, in the first or second aspect, the partition wall surrounds the heater in the internal space.

[0048] A hair dryer according to a fourth aspect of the present invention may be configured as follows: in any one of the first to third aspects, further comprising a cylindrical member extending from the air passage to the internal space, the heater being inserted into the cylindrical member, and a portion of the cylindrical member being disposed at the partition wall.

[0049] According to the above configuration, since the air is sent through the cylindrical member, the air can be sent without leaking out from the joint between the first housing and the second housing.

[0050] A hair dryer according to a fifth aspect of the present invention may be configured such that, in any one of the first to fourth aspects, the first air outlet opens toward a second direction different from the first direction.

[0051] According to the above configuration, the fan, the heater and the blow-out port are not arranged in a straight line, but are bent in the middle of the hair dryer. Therefore, a compact hair dryer can be realized, and hair can be easily dried by easy operation.

[0052] [Additional Notes] The present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope of the claims.
