[0014] Hereinafter, embodiments of the hair dryer according to the present disclosure will be described with reference to the accompanying drawings. The present disclosure is not limited to the contents described in the following embodiments, and appropriate design changes can be made within the scope of the present invention. In the drawings, the same or equivalent elements are marked with the same reference numerals, and repeated descriptions are omitted.

[0015] In the present disclosure, a "hair dryer" refers to any device that can dry a dry object such as human or animal hair (e.g., hair). The temperature of the air blown out by the hair dryer is not particularly limited. The hair dryer may be, for example, a device that blows out cold air or a device that blows out heated warm air. The hair dryer includes devices that have a drying function and functions other than the drying function. For example, a hair dryer may also have a function of imparting a beauty effect to the skin, scalp, etc. by blowing low-temperature warm air containing charged particles.

[0016] "Flow direction" and "flow path direction" refer to the flow direction of wind on an imaginary line connecting the centers of the flow path. The center of the flow path refers to the centroid of the internal shape in the cross-section of the flow path. "Flow direction" and "flow path direction" may also be directions extending in a straight line, for example, when the flow path has a curved portion or a flexure, they may be directions along an imaginary line that is partially or wholly curved or flexed. In this case, "flow direction" and "flow path direction" may also be composed of different vectors at different positions on the extension direction of an imaginary line connecting the centers of the flow path (this imaginary line is also referred to as the "flow path center line").

[0017] Two lines or two planes are "parallel" when the angle (absolute value) between them is within the range of 0°±3°. In addition, two lines or two planes are "perpendicular" when the angle (absolute value) between them is within the range of 90°±3°.

[0018] (Implementation Method 1) Figures 1 to 4 Schematic diagram briefly showing the appearance of the hair dryer 1 of this embodiment. Figure 1 is the main view, Figure 2 is the right view, Figure 3 is the rear view, Figure 4 It is a top view. Figure 5 1 is a cross-sectional schematic diagram briefly showing the internal structure of the hair dryer 1 of this embodiment. Figures 1 to 3 and Figure 5 The up-down direction in is set as the first direction D1.

[0019] Figure 6 1 is a block diagram showing an example of the configuration of the hair dryer 1 of the present embodiment. The hair dryer 1 includes, for example, a first module Q1 and a second module Q2. The first module Q1 includes a control unit 3 having a memory 31, a first electric blower 21c, and a first heater 21d, and may further include at least one of an operation unit 5 and a communication unit 6. The second module Q2 also includes a control unit 3 having a memory 31, a second electric blower 22c, and a second heater 22d, and may further include at least one of an operation unit 5 and a communication unit 6. The control unit 3 of the first module Q1 may be shared with the control unit 3 of the second module Q2, the memory 31 of the first module Q1 may be shared with the memory 31 of the second module Q2, and the operation unit 5 or the communication unit 6 of the first module Q1 may be shared with the operation unit 5 or the communication unit 6 of the second module Q2. The hair dryer 1 may control the first module Q1 and the second module Q2 separately. In addition, the control unit 3 may include at least one of a portion for comprehensively controlling the electric blowers 2c and a portion for comprehensively controlling the heaters 2d, and these portions may control the electric blowers 2c and the heaters 2d.

[0020] The hair dryer 1 of this embodiment includes a first cylinder 21 including a first electric blower 21c and a first heater 21d, a second cylinder 22 including a second electric blower 22c and a second heater 22d, and a control unit 3. The control unit 3 includes a memory 31 storing a plurality of air blowing modes having different air volumes and a plurality of heating modes having different temperatures, and independently controls the air volume of the first electric blower 21c and the temperature of the first heater 21d, and the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in one of the air blowing modes selected from the plurality of air blowing modes and the temperature included in one of the heating modes selected from the plurality of heating modes. Such a hair dryer 1 can blow a plurality of air having different air volumes and temperatures, and thus can set various air volumes and temperatures of the air blown from the hair dryer 1, and can effectively supply air to the hair.

[0021] The hair dryer 1 includes a plurality of cylinders 2 and a control unit 3 as main components. The plurality of cylinders 2 may be connected to each other by a grip 4 or a support member described later. In addition, a power supply line (not shown) is connected to the cylinder 2, the grip 4 or the support member.

[0022] (Cylinder 2) The hair dryer 1 includes a plurality of cylinders 2. The number of cylinders 2 may be 2 or more (≥2), or may be 3 or more. The plurality of cylinders 2 includes a first cylinder 21 and a second cylinder 22. The first cylinder 21 and the second cylinder 22 are sometimes collectively referred to as cylinders 2. For ease of explanation, the direction in which the central axis of the first cylinder 21 extends (equivalent to Figure 1~Figure 3 and Figure 5 The up and down direction) is called the first direction D1.

[0023] The cylinder 2 refers to a cylindrical shell with a space inside. The cross-section of the cylinder 2 can be any of a circular, elliptical, oblong, polygonal, etc. An air passage (also called a flow passage) for the air sucked in from the outside to flow is formed inside each cylinder 2. Preferably, at least one air passage is formed in each cylinder 2. The air passage provided by the first cylinder 21 is called the first air passage F1, and the air passage provided by the second cylinder 22 is called the second air passage F2. The first air passage F1 and the second air passage F2 can be collectively referred to as the air passage F.

[0024] The first cylinder 21 includes: a first blowing outlet 21a, an opening for blowing air to the outside, a first air intake port 21b, an opening for sucking air from the outside, a first electric blower 21c, which sends air from the air intake port side to the blowing outlet side, and a first heater 21d. The second cylinder 22 includes a second blowing outlet 22a, a second air intake port 22b, a second electric blower 22c, and a second heater 22d. The first blowing outlet 21a and the first air intake port 21b are connected to the first air path F1, and the second blowing outlet 22a and the second air intake port 22b are connected to the second air path F2. The first blowing outlet 21a and the second blowing outlet 22a can be collectively referred to as blowing outlets 2a. The first air intake port 21b and the second air intake port 22b can be collectively referred to as air intake ports 2b. The first electric blower 21c and the second electric blower 22c can be collectively referred to as electric blowers 2c. The first heater 21d and the second heater 22d can be collectively referred to as heater 2d. In addition, in Figures 1 to 5 , an example of the hair dryer 1 including a plurality of air inlets (ie, the first air inlet 21 b and the second air inlet 22 b ) is shown, but the hair dryer 1 of the present embodiment may include a single common air inlet.

[0025] The air flowing through the air passage F in each cylinder 2 can be heated by each heater 2d. When the heater 2d is in an energized state (referred to as an on state), warm air is blown out from the blowout port 2a of the cylinder 2 equipped with the heater 2d. When the heater 2d is in an off state (referred to as an off state), cold air that is not heated by the heater 2d is blown out from the blowout port 2a of the cylinder 2 equipped with the heater 2d. "Heating" means that the temperature of the gas discharged from the area where the heater is installed is higher than the temperature of the gas (e.g., air) before being guided to the area where the heater is installed.

[0026] The first cylinder 21 and the second cylinder 22 are preferably arranged in parallel with each other. They are arranged in parallel with each other means that the direction in which the central axis of the first cylinder 21 extends is parallel to the direction in which the central axis of the second cylinder 22 extends. The direction in which the central axis of the cylinder 2 extends (also called the long side direction) is equivalent to the straight line passing through the centroid of the cross section of the cylinder 2.

[0027] The first cylinder 21 and the second cylinder 22 are preferably arranged in a manner that the first outlet 21a and the second outlet 22a are separated from each other. For example, preferably, the first cylinder 21 and the second cylinder 22 are arranged in parallel with each other, and the first outlet 21a and the second outlet 22a are separated from each other along a direction inclined to the first direction D1 (typically, a direction perpendicular to the first direction D1) (see Figure 1 ). When the first outlet 21a and the second outlet 22a are separated from each other, the air sent out from the first outlet 21a and the second outlet 22a is prevented from immediately merging, thereby effectively generating a drape phenomenon described later. Therefore, air can be effectively supplied from the hair dryer 1 to the hair.

[0028] As described above, the first cylinder 21 includes the first blowout port 21a, and the second cylinder 22 includes the second blowout port 22a. The blowout port 2a may be formed on one end surface of each cylinder 2, or may be formed on the side surface of each cylinder 2. Figure 1 In the figures, the hair dryer 1 is shown in which each blow-out port 2a is formed on the side surface of each cylinder 2, but the position of each blow-out port 2a is not limited to this position.

[0029] (Control Unit 3) The control unit 3 includes a memory 31 that stores multiple air supply modes with different air volumes and multiple heating modes with different temperatures, and independently controls the first electric blower 21c and the first heater 21d, and the second electric blower 22c and the second heater 22d according to an air supply mode selected from the above-mentioned multiple air supply modes and a heating mode selected from the above-mentioned multiple heating modes.

[0030] The plurality of air supply modes include a strong air mode and a weak air mode with a smaller air volume than the strong air mode. Such a hair dryer 1 can deliver a plurality of air with different air volumes, and therefore, the air volume of the air delivered from the hair dryer 1 can be variously set. For example, when the set speed of the electric air blower 2c for implementing the strong air mode is set to X, it is preferred that the set speed of the electric air blower 2c for implementing the weak air mode is 90% or less of X.

[0031] The air volume of the strong wind mode S1 for the first electric blower 21c and the air volume of the strong wind mode S2 for the second electric blower 22c may be the same or different from each other. The air volume of the weak wind mode W1 for the first electric blower 21c and the air volume of the weak wind mode W2 for the second electric blower 22c may be the same or different from each other. The plurality of air supply modes may further include an action mode of air volume other than the air volume of the strong wind mode and the air volume of the weak wind mode on the basis of the strong wind mode and the weak wind mode. In such a hair dryer 1, the types of air volumes of the air sent from each cylinder 2 increase.

[0032] The plurality of heating modes include a high temperature mode and a low temperature mode having a lower temperature than the high temperature mode. Such a hair dryer 1 can deliver a plurality of winds having different temperatures, and thus the temperature of the wind delivered from the hair dryer 1 can be variously set. For example, when the set temperature of the heater 2d for implementing the high temperature mode is set to Y, the set temperature of the heater 2d for implementing the low temperature mode is preferably 5°C or more lower than Y.

[0033] The power applied to the heater 2d in the high temperature mode is greater than the power applied to the heater 2d in the low temperature mode. The power applied to the heater 2d in the low temperature mode may also be zero. The power applied to the heater being zero means that the heater is in the off state.

[0034] The temperature of the high temperature mode H1 for the first heater 21d and the temperature of the high temperature mode H2 for the second heater 22d may be the same or different. The temperature of the low temperature mode L1 for the first heater 21d and the temperature of the low temperature mode L2 for the second heater 22d may be the same or different. The plurality of heating modes may further include an operation mode of a temperature other than the temperature of the high temperature mode and the temperature of the low temperature mode in addition to the high temperature mode and the low temperature mode. In such a hair dryer 1, the types of temperatures of the air delivered from each cylinder 2 increase.

[0035] The memory 31 stores: a first operation mode including a strong wind mode and a high temperature mode, a second operation mode including a strong wind mode and a low temperature mode, a third operation mode including a weak wind mode and a high temperature mode, and a fourth operation mode including a weak wind mode and a low temperature mode. The control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d, and the air volume of the second electric blower 22c and the temperature of the second heater 22d independently of each other based on the air volume included in the air supply mode and the temperature included in the heating mode of the first operation mode, the second operation mode, the third operation mode, or the fourth operation mode.

[0036] Specifically, the memory 31 stores: a first action mode M11, which includes a strong wind mode S1 for the first electric blower 21c and a high temperature mode H1 for the first heater 21d; a second action mode M12, which includes a strong wind mode S1 for the first electric blower 21c and a low temperature mode L1 for the first heater 21d; a third action mode M13, which includes a weak wind mode W1 for the first electric blower 21c and a high temperature mode H1 for the first heater 21d; and a fourth action mode M14, which includes a weak wind mode W1 for the first electric blower 21c and a low temperature mode L1 for the first heater 21d.

[0037] In addition, the memory 31 stores: a first action mode M21, which includes a strong wind mode S2 for the second electric blower 22c and a high temperature mode H2 for the second heater 22d; a second action mode M22, which includes a strong wind mode S2 for the second electric blower 22c and a low temperature mode L2 for the second heater 22d; a third action mode M23, which includes a weak wind mode W2 for the second electric blower 22c and a high temperature mode H2 for the second heater 22d; and a fourth action mode M24, which includes a weak wind mode W2 for the second electric blower 22c and a low temperature mode L2 for the second heater 22d.

[0038] The control unit 3 alternately switches between a first state and a second state, wherein the first state controls the air volume of the electric blower 2c and the temperature of the heater 2d of at least one of the first cylinder 21 and the second cylinder 22 based on the air volume included in the air supply mode and the temperature included in the heating mode of the first action mode, the second action mode, the third action mode or the fourth action mode, and the second state controls the air volume of the electric blower 2c and the temperature of the heater 2d based on the air volume included in the air supply mode and the temperature included in the heating mode of an action mode different from the first state.

[0039] In the hair dryer 1 of the present embodiment, since each cylinder 2 can alternately send out a plurality of winds of which at least one of air volume and temperature is different from each other, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, low warm wind and high warm wind can be alternately blown to each of a plurality of adjacent areas, and wind with a large air volume and wind with a small air volume can be alternately blown to each of a plurality of adjacent areas. In addition, high-temperature wind with a large air volume and low-temperature wind with a low air volume can be alternately blown to each of a plurality of adjacent areas, and high-temperature wind with a low air volume and low-temperature wind with a large air volume can also be alternately blown. Therefore, for example, quick drying can be improved while preventing hair damage.

[0040] After the hair dryer 1 is activated, the control unit 3 starts the first state or the second state based on an instruction from the user, etc., and then alternately switches between the first state and the second state. That is, the hair dryer 1 dries the hair while alternately repeating the first state and the second state.

[0041] The first state refers to a state in which the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d according to the air volume included in the air supply mode and the temperature included in the heating mode of the prescribed operation mode M1, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d according to the air volume included in the air supply mode and the temperature included in the heating mode of the prescribed operation mode M2. The second state refers to a state in which the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d according to the air volume included in the air supply mode and the temperature included in the heating mode of the operation mode M1' different from the operation mode M1 in the first state, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d according to the air volume included in the air supply mode and the temperature included in the heating mode of the operation mode M2' different from the operation mode M2 ​​in the first state. Here, the motion modes M1 and M1' are the first motion mode M11, the second motion mode M12, the third motion mode M13 or the fourth motion mode M14. The motion modes M2 and M2' are the first motion mode M21, the second motion mode M22, the third motion mode M23 or the fourth motion mode M24 except the motion modes M1 and M1'.

[0042] The switching between the first state and the second state can be determined based on, for example, an instruction from a user, elapsed time, or input from a sensor. As an example of the control unit 3 switching between the first state and the second state based on elapsed time, for example, an example of switching to the second state when a predetermined time has elapsed since the control unit 3 started the first state can be cited. The predetermined drying time refers to, for example, a drying time input in advance by a user (for example, a drying time input by a user to an operation unit or an external terminal); a drying time predicted by the control unit 3 based on hair data such as hair length and hair volume; a drying time calculated by the control unit 3 and the like by machine learning on the switching timing, etc. The above-mentioned hair data can be data input in advance by a user to an operation unit or an external terminal, or, for example, data calculated based on an image captured by a camera.

[0043] In the first state, the action mode M1 for the first electric blower 21c and the first heater 21d and the action mode M2 ​​for the second electric blower 22c and the second heater 22d may be the same, but preferably different. That is, for example, preferably one or more of the rotation speeds of the first electric blower 21c and the second electric blower 22c and the set temperatures of the first heater 21d and the second heater 22d are different. Such a hair dryer 1 can simultaneously send out a plurality of winds that are different in at least one of the air volume and temperature. Similarly, in the second state, the action mode M1' for the first electric blower 21c and the first heater 21d and the action mode M2' for the second electric blower 22c and the second heater 22d may be the same, but preferably different.

[0044] Preferably, the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d in the first state based on the air volume included in the strong wind mode S1 and the temperature included in the high temperature mode H1 possessed by the first action mode M11, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the strong wind mode S2 and the temperature included in the low temperature mode L2 possessed by the second action mode M22. In the second state, the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong wind mode S1 and the temperature included in the low temperature mode L1 possessed by the second action mode M12, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the strong wind mode S2 and the temperature included in the high temperature mode H2 possessed by the first action mode M21. In such a hair dryer 1, each cylinder 2 can alternately send out warm air and cold air. Therefore, even when the hair dryer 1 is maintained at a fixed position and in a fixed posture, warm air and cold air can be alternately blown to each of a plurality of adjacent areas, thereby effectively supplying air to the hair while preventing hair damage.

[0045] The control unit 3 may be mounted on a control substrate provided in the cylinder 2, or may be provided on the gripping portion 4. In the former case, each cylinder 2 may have a control substrate, but the control substrate may be provided in an integrated manner. When the control substrate is arranged between the air inlet 2b and the heater 2d, the control substrate is cooled by the air flowing inside the cylinder 2. The control unit 3 is composed of a CPU and the like, and executes a program stored in a memory 31 (also referred to as a storage device). The control unit 3 may also be a microcomputer including a CPU and a memory 31 and the like. The memory 31 may be implemented by various ROMs, RAMs, and the like. The memory 31 may be a memory provided in the hair dryer 1, a memory that can be attached and detached to the hair dryer 1, or an external recording medium that can be accessed from the hair dryer 1.

[0046] The hair dryer 1 may also include an operation unit 5. The operation unit 5 is provided on, for example, the grip 4, a support member, or the like. When the hair dryer 1 includes the operation unit 5, the operation unit 5 outputs the user's operation content to the control unit 3, and the control unit 3 receives the operation content. The hair dryer 1 may include a communication unit 6 instead of the operation unit 5, or in addition to the operation unit 5. The control unit 3 may also receive the operation content input to the external terminal or the like owned by the user through the communication unit 6. The communication unit 6 may be connected to a communication line through a router, a gateway, or the like, and may perform unidirectional or bidirectional communication with the external terminal through the communication line, or may directly perform unidirectional or bidirectional communication with the external terminal through short-range wireless communication such as Bluetooth (registered trademark) without using a communication line.

[0047] The set temperature of the air blown out from the air outlet 2a is a temperature set by the user or a temperature preset in the automatic operation mode. The set temperature may be acquired by the control unit 3 from the user or the like via the operation unit 5 or the communication unit 6, or may be determined by the control unit 3.

[0048] (Handle 4) The hair dryer 1 of this embodiment may further include a grip portion 4 (see Figure 1 The grip 4 is a portion that serves as a grip for the user when using the hair dryer 1. The hair dryer 1 may be a fixed type hair dryer that does not include the grip 4, for example.

[0049] From the viewpoint of eliminating the burden on the user, the grip 4 is preferably installed at a position close to the center of gravity of the hair dryer 1. In addition, the grip 4 is preferably connected to each cylinder 2. The grip 4 may be connected to each cylinder 2 via, for example, a support member.

[0050] When the first cylinder 21 and the second cylinder 22 are arranged in parallel with each other, the grip 4 may be arranged in parallel with these cylinders 2, or may be arranged in a direction inclined relative to these cylinders 2. For example, when the first cylinder 21 and the second cylinder 22 are arranged in parallel with each other, and the grip 4 is arranged in parallel with these cylinders 2, the hair dryer 1 as a whole may have an I-shaped appearance. In addition, when the first cylinder 21 and the second cylinder 22 are arranged in parallel with each other, and the grip 4 is arranged in a direction inclined relative to these cylinders 2 (for example, a vertical direction), the hair dryer 1 as a whole may have a T-shaped or L-shaped appearance.

[0051] The grip portion 4 may be provided with an operating portion 5. When the hair dryer 1 is used, the user operates the operating portion 5 (e.g., a power switch) to start or stop the operation of the hair dryer 1. In addition, the user can adjust the temperature (warm air / cold air), operation mode, air volume, wind direction, etc. of the air from the blow-out port 2a by operating the operating portion 5 (e.g., an operation button). The operating portion 5 may also include a lever, a cyclic stick, etc. For example, in a case where a portion of the cylinder 2 is rotatable and the operating portion 5 includes a lever, a cyclic stick, etc., if the sliding direction of the lever or the cyclic stick corresponds to the rotation direction of the cylinder 2, the user can easily identify the rotation direction by sight or feeling. Hereinafter, the structure and the like of the hair dryer 1 according to the present embodiment will be further described.

[0052] As described above, preferably, the first cylinder 21 and the second cylinder 22 are arranged in a manner that the first outlet 21a and the second outlet 22a are separated from each other. In this case, the drooping phenomenon is effectively generated. The drooping phenomenon refers to a phenomenon in which, when air is blown from the hair dryer 1 to the hair, the hair is undulated in the area opposite to the hair dryer 1. For example, in the case of drying hair, when the hair dryer 1 is started and air is blown out from each outlet 2a, high wind speed areas are formed radially from each outlet 2a. On the other hand, the area between the outlets 2a becomes a closed area where no air is blown out, but the air passing through the closed area is drawn into the high wind speed area, so that the area between the outlets 2a becomes a low wind speed area where air flows toward the hair. In this way, if the low wind speed area is formed in a manner sandwiched by a plurality of high wind speed areas, the blown wind is disturbed, and a turbulent flow of wind such as a vortex is generated in the low wind speed area. If turbulence is generated, the hair is rolled up by the turbulent flow, and the hair can be dried at a high drying speed. In addition, the wind blown out from each air outlet 2a hits the scalp and rebounds, thereby generating wind that causes the hair to leave the scalp in the low wind speed area, and further generating turbulence.

[0053] The hair blown by the air in the high wind speed area is pressed against the scalp (head) by the wind pressure. In contrast, the hair in the low wind speed area where turbulence is generated is rolled up by the turbulence and separated from the scalp (head) and floats up. As a result, the hair fluctuates in the area opposite to the hair dryer 1. In the present disclosure, this phenomenon is called the draping phenomenon. In addition, the wind that generates the high wind speed area and the low wind speed area that generates the draping phenomenon is also called the draping wind.

[0054] The first cylinder 21 and the second cylinder 22 preferably have similar shapes. In addition, it is also preferred that the first cylinder 21 and the second cylinder 22 are symmetrical with respect to a plane passing through the middle of them along the first direction D1. For example, it is preferred that at least one of the outer shape, the internal flow path area, the shape and position of the blow-out port 2a, and the shape and position of the air inlet, etc., is symmetrical with respect to the above-mentioned plane passing through the middle of the first cylinder 21 and the second cylinder 22. As a result, the posture of the hair dryer 1 is stabilized, and the operability of the hair dryer 1 is improved.

[0055] The blowout port 2 a provided in each cylinder 2 may be formed on an end surface (also referred to as an end wall) of each cylinder 2 , or may be formed on a side surface of each cylinder 2 .

[0056] The shape of the blowout port 2a of each cylinder 2 is not particularly limited, and may be, for example, circular, polygonal, or elongated. In addition, the shapes of the blowout ports 2a of the first cylinder 21 and the second cylinder 22 may be the same or different from each other. A circular shape also includes an elliptical shape.

[0057] The blow outlet 2a has an elongated shape means that, when the blow outlet 2a is observed from the front, the longest length passing through the centroid of the blow outlet 2a is greater than the shortest length of the blow outlet 2a. Therefore, if the longest length passing through the centroid of the blow outlet 2a is set to La, and the shortest length of the blow outlet 2a is set to Sa, the blow outlet 2a has an elongated shape means that the blow outlet 2a satisfies La>Sa. In addition, it is preferred that the aspect ratio (La / Sa) obtained by dividing the longest length La passing through the centroid of the blow outlet 2a by the shortest length Sa of the blow outlet is greater than 3 and less than 20. Thus, it is preferred that the above-mentioned aspect ratio of the blow outlet 2a possessed by at least one of the cylinders 2 is greater than 3 and less than 20. The aspect ratio is more preferably greater than 5, and even more preferably greater than 6.

[0058] The opening direction of the first outlet 21a and the opening direction of the second outlet 22a may be parallel to each other, or may be inclined close to each other, or may be inclined away from each other. As described above, the control unit 3 may control the opening direction of the outlet 2a. The opening direction of the outlet 2a refers to the direction toward which the centroid of the outlet 2a is directed, which substantially corresponds to the flow direction (wind direction) of the wind near the outlet 2a.

[0059] For at least one of the first cylinder 21 and the second cylinder 22, the end portion (also referred to as the blowing portion) on the blowing port 2a side of the cylinder 2 may be movable or rotatable. The blowing portion may, for example, rotate around the direction in which the central axis of the cylinder 2 having the blowing portion extends, or may rotate in a direction inclined to the direction in which the central axis extends.

[0060] The rotatable blow-out portion may be a blow-out portion that is manually rotated by a user, or a blow-out portion that can be controlled to rotate by the control unit 3. In addition, the rotatable blow-out portion may also be composed of a flexible member. The rotatable blow-out portion is preferably a blow-out portion that can be locked in rotation at any angle. For example, it is preferred that the portion can be locked at an angle that allows the first blow-out port 21a and the second blow-out port 22a to clamp the hair. The rotation angle is not particularly limited, for example, in one cylinder 2, the rotatable angle is 0 to 360°.

[0061] When the blowing part of the first cylinder 21 and the blowing part of the second cylinder 22 are both rotatable, they can rotate in the same direction or in different directions. In addition, for example, when the first cylinder 21 and the second cylinder 22 are arranged in parallel with each other, the rotation stop position can be a symmetrical position relative to the plane extending along the first direction D1 passing through them, or an asymmetrical position. For example, the control unit 3 can control the rotation direction of the above-mentioned blowing part to be the same rotation direction as each other, or to be the opposite rotation direction. In addition, the control unit 3 can also control the rotation direction of the above-mentioned blowing part in a manner that the period during which the rotation direction becomes the same direction and the period during which it becomes the opposite direction over time is located at an alternating position. The "rotation direction" mentioned here refers to: for example, the rotation direction when each cylinder 2 is observed from the first direction D1. The rotation direction includes clockwise (right-handed) and counterclockwise (left-handed).

[0062] like Figure 1 As shown in the figures, at least one of the first cylinder 21 and the second cylinder 22 may have a shape whose diameter decreases toward the front end (also referred to as a tapered shape). The front end refers to the end on the opposite side of the air intake port among the ends of each cylinder 2. The tapered shape is, for example, a shape with a relatively rounded front end, a conical shape, or a cone shape.

[0063] The blow-out outlet 2a provided in at least one of the first cylinder 21 and the second cylinder 22 may also have a blow-out fin (also referred to as a wind direction changing plate) near the blow-out outlet 2a. The blow-out fin is an air guide component for controlling the flow direction of air or rectifying the flow of air. In the blow-out outlet 2a provided with the blow-out fin, a plurality of blow-out fins may be arranged. The blow-out fin may be fixed to the blow-out outlet 2a, or may be a component that allows the user to manually change the angle of the air suction fin, or may be a component that allows the angle to be changed by the control unit 3. The hair dryer 1 may make the flow direction (referred to as wind direction) of the wind blown out from the blow-out outlet 2a provided with the blow-out fin, for example, in mutually opposite directions (inward) or in mutually separated directions (outward). The blow-out fin may make the wind blow out toward the front end side of the cylinder 2, or may blow out toward the side opposite to the front end side.

[0064] In each air passage F, an electric blower 2c may be arranged on the upstream side, and a heater 2d may be arranged on the downstream side. The upstream side and the downstream side refer to the upstream side and the downstream side in the air flow direction, respectively. The air inlet 2b side is the upstream side, and the air outlet 2a side is the downstream side.

[0065] The position of the first electric blower 21c in the first air passage F1 and the position of the second electric blower 22c in the second air passage F2 may be the same as or different from each other.

[0066] The electric blower 2c is a general term for a mechanism that uses electricity to supply air. For example, the electric blower may be a mechanism that supplies air by rotating a component that forms an airflow, such as a fan, using electricity, or may be a mechanism that generates airflow by generating vibrations, etc., using electricity to form a high-pressure portion and a low-pressure portion. For example, the electric blower preferably includes a fan and a motor that drives the fan. The arrangement relationship between the fan and the motor in the flow direction is not particularly limited. For example, the fan may be arranged in a manner such that the fan is located on the upstream side and the motor is located on the downstream side.

[0067] As the motor, for example, a brushless motor, an induction motor, a synchronous reluctance motor, etc. are preferably used. Among them, the motor is more preferably a brushless motor, and even more preferably a brushless DC motor.

[0068] Since the brushless motor does not have brushes that contact the rotor, the sound generated by the contact between the brushes and the rotor can be suppressed. Therefore, further silencing can be achieved. In the brushless motor, for example, it includes: a motor with a permanent magnet for excitation on the rotor side and an armature winding on the stator side; a motor that uses a sensor (for example, a Hall sensor, etc.) for detecting rotor signals and feeding back to the inverter to control the power supply instead of using brushes for power switching based on the position change of the commutator, etc. In addition, the induction motor can also be a motor that generates a sine wave that is phase-shifted from the power supply to rotate the magnetic field. The synchronous reluctance motor is a type of synchronous motor, for example, it can be a motor that rotates as an induction motor at startup and rotates synchronously with the power supply frequency during operation.

[0069] Since each cylinder 2 has an electric blower 2c, the hair dryer 1 as a whole includes a plurality of electric blowers 2c. By making the number of electric blowers 2c multiple, the size of the sound generated when a certain air volume is blown out can be made smaller than when a single electric blower is used to blow out air. Thus, the hair dryer 1 as a whole can be made quieter. In this way, the hair dryer 1 of this embodiment can achieve a large air volume while being quiet.

[0070] The air intake port 2b provided in at least one of the first cylinder 21 and the second cylinder 22 may also be provided with an air intake fin (not shown) near the air intake port 2b. The blow-out fin is an air guide component for controlling the flow direction of air or rectifying the flow of air. In the air intake port 2b provided with the air intake fin, a plurality of air intake fins may also be arranged. The air intake fin may be fixed on the air intake port 2b, or may be a component that the user can manually change the angle of the air intake fin, or may be a component that the angle can be changed by the control unit 3.

[0071] (Implementation Method 2) In the present embodiment, the features unique to the present embodiment will be mainly described, and the description of the contents overlapped with those in the above-mentioned embodiment will be omitted. The hair dryer 1 of the present embodiment is substantially the same as the hair dryer 1 of the first embodiment except that the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong air mode S1 and the temperature included in the high temperature mode H1 of the first operation mode M11 in the first state, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the weak air mode W2 and the temperature included in the high temperature mode H2 of the third operation mode M23 in the second state, controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the weak air mode W1 and the temperature included in the high temperature mode H1 of the third operation mode M13 in the second state, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the strong air mode S2 and the temperature included in the high temperature mode H2 of the first operation mode M21.

[0072] The hair dryer 1 of this embodiment can send strong wind and weak wind at the same time, so it can produce a drooping phenomenon, thereby achieving rapid drying. In addition, since each cylinder 2 can send strong wind and weak wind alternately, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, it is possible to alternately blow strong wind and weak wind to each of a plurality of adjacent areas. That is, in the hair dryer 1 of this embodiment, since the configuration of the strong wind and weak wind that produce the drooping phenomenon is exchanged, it is possible to add an action such as hair shaking to the drooping phenomenon. As a result, the hair dryer 1 of this embodiment can achieve rapid drying more effectively.

[0073] (Implementation Method 3) In the present embodiment, the features unique to the present embodiment will be mainly described, and the description of the contents overlapped with those in the above-mentioned embodiment will be omitted. The hair dryer 1 of the present embodiment is substantially the same as the hair dryer 1 of the first embodiment except that the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong air mode S1 and the temperature included in the high temperature mode H1 of the first operation mode M11 in the first state, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the weak air mode W2 and the temperature included in the low temperature mode L2 of the fourth operation mode M24, and controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the weak air mode W1 and the temperature included in the low temperature mode L1 of the fourth operation mode M14 in the second state, and controls the air volume of the first electric blower 21c and the temperature of the first heater 22d based on the air volume included in the strong air mode S2 and the temperature included in the high temperature mode H2 of the first operation mode M21.

[0074] In the hair dryer 1 of the present embodiment, each cylinder 2 can alternately send out warm air and cold air, so even when the hair dryer 1 is maintained at a fixed position and a fixed posture, warm air and cold air can be alternately blown to each of the adjacent multiple areas, so that wind can be effectively supplied to the hair while preventing hair damage. In addition, such a hair dryer can also send out strong wind and weak wind at the same time, so that a draping phenomenon can be generated, thereby achieving rapid drying. In addition, since each cylinder 2 can alternately send out strong wind and weak wind, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, strong wind and weak wind can be alternately blown to each of the adjacent multiple areas. That is, in the hair dryer 1 of the present embodiment, since the arrangement of the strong wind and weak wind that generate the draping phenomenon is exchanged, an action such as hair shaking can be added to the draping phenomenon. As a result, the hair dryer 1 of the present embodiment can achieve rapid drying more effectively.

[0075] (Implementation Method 4) In the present embodiment, the features unique to the present embodiment will be mainly described, and the description of the contents overlapped with those in the above-mentioned embodiment will be omitted. The hair dryer 1 of the present embodiment is substantially the same as the hair dryer 1 of the first embodiment except that the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong air mode S1 and the temperature included in the low temperature mode L1 of the second operation mode M12 in the first state, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the weak air mode W2 and the temperature included in the high temperature mode H2 of the third operation mode M23, and controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the weak air mode W1 and the temperature included in the high temperature mode H1 of the third operation mode M13 in the second state, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the strong air mode S2 and the temperature included in the low temperature mode L2 of the second operation mode M22.

[0076] In the hair dryer 1 of the present embodiment, each cylinder 2 can alternately send out warm air and cold air, so even when the hair dryer 1 is maintained at a fixed position and a fixed posture, warm air and cold air can be alternately blown to each of the adjacent multiple areas, so that wind can be effectively supplied to the hair while preventing hair damage. In addition, such a hair dryer can also send out strong wind and weak wind at the same time, so that a draping phenomenon can be generated, thereby achieving rapid drying. In addition, since each cylinder 2 can alternately send out strong wind and weak wind, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, strong wind and weak wind can be alternately blown to each of the adjacent multiple areas. That is, in the hair dryer 1 of the present embodiment, since the arrangement of the strong wind and weak wind that generate the draping phenomenon is exchanged, an action such as hair shaking can be added to the draping phenomenon. As a result, the hair dryer 1 of the present embodiment can achieve rapid drying more effectively.

[0077] (Implementation Method Five) In this embodiment, features unique to this embodiment are mainly described, and description of contents overlapping with those in the above-described embodiment will be omitted. The hair dryer 1 of the present embodiment is substantially the same as the hair dryer 1 of the first embodiment except that the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong air mode S1 and the temperature included in the low temperature mode L1 of the second operation mode M12 in the first state, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the weak air mode W2 and the temperature included in the low temperature mode L2 of the fourth operation mode M24. In the second state, the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the weak air mode W1 and the temperature included in the low temperature mode L1 of the fourth operation mode M14, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the strong air mode S2 and the temperature included in the low temperature mode L2 of the second operation mode M22.

[0078] The hair dryer 1 of this embodiment can send strong wind and weak wind at the same time, so that the draping phenomenon can be generated, thereby achieving rapid drying. In addition, since each cylinder 2 can send strong wind and weak wind alternately, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, strong wind and weak wind can be blown alternately to each of a plurality of adjacent areas. That is, in the hair dryer 1 of this embodiment, since the configuration of the strong wind and weak wind that generate the draping phenomenon is exchanged, an action such as hair shaking can be added to the draping phenomenon. As a result, the hair dryer 1 of this embodiment can achieve rapid drying more effectively.

[0079] (Implementation Method 6) In the present embodiment, the features unique to the present embodiment will be mainly described, and the description of the contents overlapped with those in the above-mentioned embodiment will be omitted. The hair dryer 1 of the present embodiment is substantially the same as the hair dryer 1 of the first embodiment except that the control unit 3 controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the weak air mode W1 and the temperature included in the high temperature mode H1 of the third operation mode M13 in the first state, and controls the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the weak air mode W2 and the temperature included in the low temperature mode L2 of the fourth operation mode M24, and controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the weak air mode W1 and the temperature included in the low temperature mode L1 of the fourth operation mode M14 in the second state, and controls the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the weak air mode W2 and the temperature included in the high temperature mode H2 of the third operation mode M23.

[0080] In the hair dryer 1 of this embodiment, each cylinder 2 can alternately send out warm air and cold air. Therefore, even when the hair dryer 1 is maintained at a fixed position and in a fixed posture, warm air and cold air can be alternately blown to each of a plurality of adjacent areas, thereby effectively supplying air to the hair while preventing hair damage.

[0081] (Implementation Method Seven) In the present embodiment, the features unique to the present embodiment will be mainly described, and the description of the contents overlapped with those in the above-mentioned embodiment will be omitted. The hair dryer 1 of the present embodiment is substantially the same as the hair dryer 1 of the first embodiment except that the control unit 3 alternately switches between a first state in which the air volume of the first electric blower 21c and the temperature of the first heater 21d are controlled based on the air volume included in the air supply mode and the temperature included in the heating mode of the first operation mode M11, the second operation mode M12, the third operation mode M13, or the fourth operation mode M14, and the second electric blower 22c is not driven, and a second state in which the air volume of the second electric blower 22c and the temperature of the second heater 22d are controlled based on the air volume included in the air supply mode and the temperature included in the heating mode of the first operation mode M21, the second operation mode M22, the third operation mode M23, or the fourth operation mode M24.

[0082] The hair dryer 1 of this embodiment can alternately blow air from the first cylinder 21 and the second cylinder 22, and the air blown from the first cylinder 21 and the air blown from the second cylinder 22 have at least one of a volume and a temperature different from each other, thereby preventing hair damage and improving quick drying properties.

[0083] “Not driving the electric blower 2c” means that the electric blower 2c is “substantially stopped” in addition to being in a state where the electric blower 2c is stopped (i.e., stopped). The “substantially stopped state” means that the electric blower 2c is driven at a low rotation speed so that the wind from the blower outlet 2a of the cylinder 2 having the electric blower 2c does not hit the hair.

[0084] The control unit 3 alternately switches between the first state and the second state. The first state refers to a state in which the control unit 3 controls the first electric blower 21c and the first heater 21d according to a prescribed action mode M1, and does not drive the second electric blower 22c. The second state refers to a state in which the control unit 3 does not drive the first electric blower 21c, and controls the second electric blower 22c and the second heater 22d according to a prescribed action mode M1. The action mode M1 here is the first action mode M11, the second action mode M12, the third action mode M13, or the fourth action mode M14, and the action mode M2 ​​is the first action mode M21, the second action mode M22, the third action mode M23, or the fourth action mode M24. In addition, the second heater 22d can be turned off in the first state, and the first heater 21d can be turned off in the second state.

[0085] The operation mode M1 for the first electric blower 21c and the first heater 21d in the first state and the operation mode M2 ​​for the second electric blower 22c and the second heater 22d in the second state may be the same, but preferably different. Such a hair dryer 1 can simultaneously blow a plurality of winds having at least one of different air volume and temperature.

[0086] For example, the control unit 3 may control the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong air mode S1 and the temperature included in the high temperature mode H1 of the first operation mode M11 in the first state, and may not drive the second electric blower 22c. In the second state, the first electric blower 21c is not driven, but the air volume of the second electric blower 22c and the temperature of the second heater 22d are controlled based on the air volume included in the strong air mode S2 and the temperature included in the low temperature mode L2 of the second operation mode M22. In such a hair dryer 1, since the warm air is sent from the first cylinder 21 and the cold air is sent from the second cylinder 22 alternately and repeatedly, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, the hair dryer 1 can alternately and repeatedly blow warm air to one of a plurality of adjacent areas and blow cold air to another area, thereby effectively supplying air to the hair while preventing damage to the hair.

[0087] In addition, the control unit 3 may control the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong air mode S1 and the temperature included in the high temperature mode H1 of the first operation mode M11 in the first state, and may not drive the second electric blower 22c. In the second state, the first electric blower 21c is not driven, but the air volume of the second electric blower 22c and the temperature of the second heater 22d are controlled based on the air volume included in the weak air mode W2 and the temperature included in the high temperature mode H2 of the third operation mode M23. In such a hair dryer 1, since the strong air is sent from the first cylinder 21 and the weak air is sent from the second cylinder 22 alternately and repeatedly, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, the hair dryer 1 can alternately and repeatedly blow strong air to one of a plurality of adjacent areas and blow weak air to another area, and can make the hair move in a shaking manner. As a result, quick drying can be effectively achieved.

[0088] The control unit 3 may control the air volume of the first electric blower 21c and the temperature of the first heater 21d in the first state based on the air volume included in the strong air mode S1 and the temperature included in the high temperature mode H1 of the first operation mode M11, and may not drive the second electric blower 22c. In the second state, the first electric blower 21c is not driven, but the air volume of the second electric blower 22c and the temperature of the second heater 22d are controlled based on the air volume included in the weak air mode W2 and the temperature included in the low temperature mode L2 of the fourth operation mode M24. In such a hair dryer 1, since the warm air is sent from the first cylinder 21 and the cold air is sent from the second cylinder 22 alternately and repeatedly, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, the hair dryer 1 can alternately and repeatedly blow warm air to one of a plurality of adjacent areas and blow cold air to another area, thereby effectively supplying air to the hair while preventing damage to the hair. In addition, in such a hair dryer 1, since the strong wind from the first cylinder 21 and the weak wind from the second cylinder 22 are sent out alternately and repeatedly, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, the hair dryer 1 can alternately and repeatedly blow strong wind to one of a plurality of adjacent areas and blow weak wind to another area, and can make the hair move in a shaking manner. As a result, quick drying can be effectively achieved.

[0089] In addition, the control unit 3 may control the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong air mode S1 and the temperature included in the low temperature mode L1 of the second operation mode M12 in the first state, and may not drive the second electric blower 22c, and may control the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the weak air mode W2 and the temperature included in the high temperature mode H2 of the third operation mode M23 without driving the first electric blower 21c in the second state. In such a hair dryer 1, since the sending of warm air from the first cylinder 21 and the sending of cold air from the second cylinder 22 are alternately repeated, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, the hair dryer 1 can alternately and repeatedly blow warm air to one of a plurality of adjacent areas and blow cold air to another area, and can effectively supply air to the hair while preventing damage to the hair. In addition, in such a hair dryer 1, since the strong wind from the first cylinder 21 and the weak wind from the second cylinder 22 are sent out alternately and repeatedly, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, the hair dryer 1 can alternately and repeatedly blow strong wind to one of a plurality of adjacent areas and blow weak wind to another area, and can make the hair move in a shaking manner. As a result, quick drying can be effectively achieved.

[0090] In addition, the control unit 3 may control the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the strong wind mode S1 and the temperature included in the low temperature mode L1 of the second operation mode M12 in the first state, and may not drive the second electric blower 22c. In the second state, the first electric blower 21c may not be driven, but the air volume of the second electric blower 22c and the temperature of the second heater 22d may be controlled based on the air volume included in the weak wind mode W2 and the temperature included in the low temperature mode L2 of the fourth operation mode M24. In addition, in such a hair dryer 1, since the strong wind from the first cylinder 21 and the weak wind from the second cylinder 22 are alternately and repeatedly sent, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, the hair dryer 1 can alternately and repeatedly blow strong wind to one of a plurality of adjacent areas and blow weak wind to another area, and can make the hair move in a shaking manner. As a result, quick drying can be effectively achieved.

[0091] In addition, the control unit 3 may control the air volume of the first electric blower 21c and the temperature of the first heater 21d based on the air volume included in the weak air mode W1 and the temperature included in the high temperature mode H1 of the third operation mode M13 in the first state, and may not drive the second electric blower 22c, and may control the air volume of the second electric blower 22c and the temperature of the second heater 22d based on the air volume included in the weak air mode W2 and the temperature included in the low temperature mode L2 of the fourth operation mode M24 without driving the first electric blower 21c in the second state. In such a hair dryer 1, since the sending of warm air from the first cylinder 21 and the sending of cold air from the second cylinder 22 are alternately repeated, even when the hair dryer 1 is maintained at a fixed position and a fixed posture, the hair dryer 1 can alternately and repeatedly blow warm air to one of a plurality of adjacent areas and blow cold air to another area, and can effectively supply air to the hair while preventing damage to the hair.

[0092] (Variant 1) The control unit 3 may also perform other controls after performing any of the controls in the above-mentioned embodiments 1 to 7. For example, the control unit 3 may perform the control in the above-mentioned embodiment 2 after performing the control in the above-mentioned embodiment 1. In addition, the control unit 3 may switch the above-mentioned controls based on, for example, instructions from a user, elapsed time, or input from a sensor.

[0093] (Variant 2) Figure 7 1 is a schematic diagram showing an example of the blow-out port of the hair dryer 1 of this modification. In the above-mentioned first to seventh embodiments, the case where each cylinder 2 has one blow-out port 2a is described as an example. Figure 7 As shown, each cylinder 2 may also have two or more blow-out ports 2a.
