Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals.
Fig. 1 is a schematic side sectional view of a commode 60 with a hand dryer (hereinafter, simply referred to as "commode 60") provided with the hand dryer 1 of the present embodiment. Fig. 2 is a top view of the commode 60.
The commode 60 includes a faucet 61 and a sink 62. The water outlet section 61 discharges water. The washbasin 62 receives the water discharged from the water outlet portion 61 by the inner surface 62 s. In the present embodiment, the washbasin 62 is supported by the counter 63. The counter 63 is formed by an upper portion of a cabinet 64 disposed on the floor FL adjacent to the wall WL. The top surface of the counter 63 is horizontal, and an opening is formed in the center of the counter 63. The washbasin 62 is disposed so as to cover the opening of the cabinet base 63.
The outlet unit 61 is provided upright between the wash basin 62 and the wall WL in the counter unit 63, and is disposed so as to discharge water toward the inner surface 62s of the wash basin 62. The water outlet unit 61 is, for example, a faucet connected to a tap water pipe. The water outlet unit 61 penetrates the base unit 63 and is connected to a water supply channel (not shown) for supplying and discharging water. The water outlet unit 61 includes a conventional sensor, a control circuit, and an electromagnetic valve, which are not shown. The hand of the user is detected by the sensor, the solenoid valve is automatically opened, and water is discharged from the water outlet portion 61.
The washbasin 62 has a recessed shape such that the inner surface 62s is a smooth curved surface, and is formed of, for example, pottery. A drain opening 65 is formed in the lowermost bottom of the washbasin 62. The drain port 65 is an opening provided to discharge the water received by the washbasin 62 and discharged from the drain portion 61 into the sewer. A drain pipe 66 is connected to a lower portion of the drain port 65. The drain pipe 66 has a drain trap (not shown), and is connected to a sewer (not shown) via the drain trap.
The drain port 65 is provided with a drain plug 67 that can switch the opening and closing of the drain port 65. The drain plug 67 is configured to be moved up and down by a user operating a lever (not shown) provided on the commode 60, for example, to switch the opening and closing of the drain port 65. When the drain plug 67 is located at the lower end of the movable range, the drain port 65 is closed, and the water drained from the drain unit 61 can be stored in the wash basin 62. When the drain plug 67 is located at the upper end of the movable range, the drain port 65 is opened, and the water discharged from the spout 61 is discharged through the drain pipe 66.
The washbasin 60 is provided with the hand dryer 1. The hand dryer 1 includes a nozzle unit 10, a blower 20, a distance detection mechanism 30, a hand detection mechanism 40, and a control unit 50.
The nozzle portion 10 is provided with an outlet 11 that blows air in a preset blowing direction D1. In the present embodiment, the hand dryer 1 has a tubular body 12. The main body 12 is provided upright between the wash basin 62 and the wall WL in the counter 63 so as to be aligned with the outlet unit 61, and is curved toward the wash basin 62. The nozzle portion 10 is formed at the front end portion of the curved main body portion 12 and is disposed above the washbasin 62. The air outlet 11 is formed in a portion facing the washbasin 62 in the front end portion of the main body 12. The blowing direction D1 of the blowing outlet 11 is a direction toward the inner surface 62s of the washbasin 62. The blowing direction D1 is set so as not to intersect the drain opening 65 formed in the washbasin 62. This prevents the air blown out from the air outlet 11 from directly flowing into the drain pipe 66.
Fig. 3 is a bottom view of the nozzle unit 10. As shown in fig. 3, the air outlet 11 is formed in an elongated slit shape. The air outlet 11 extends long in the direction in which the front end portion of the main body 12 extends. The size of the slit width (width in the short-side direction) of the air outlet 11 is set to, for example, 2mm or less.
As shown in fig. 1, the main body 12 extends through the base 63 and is fixed to the base 63 using, for example, a fixing nut not shown. Below the counter 63, the main body 12 is connected to the air supply duct 13. The air duct 13 is formed in a tubular shape, and connects the main body 12 and the blower 20. The air supply duct 13 is formed of, for example, a flexible resin for ease of construction.
The blower 20 sends out air to be blown out from the air outlet 11 to the nozzle portion 10. In the present embodiment, the blower 20 includes a motor and a turbo fan rotated by the motor, and is configured to generate high-pressure air. The blower 20 is housed in a power unit case 21 provided below the cabinet unit 63. The power unit case 21 is provided on the wall WL inside the case 64. The power unit casing 21 is provided with an air inlet (not shown) for allowing the blower 20 to take in air from the outside of the power unit casing 21. An air filter for preventing dust from entering is detachably provided in the air inlet. Examples of the air filter include a mesh filter, a hepa (high Efficiency Particulate air) filter, and a sterilizing filter. The intake port communicates with the intake side of the blower 20. Further, an exhaust side of the blower 20 is connected to the blower duct 13. The high-pressure air generated by the blower 20 is sent to the nozzle 10 through the air duct 13 and the main body 12, and is blown out from the air outlet 11 as high-speed air. The speed of the air blown out from the air outlet 11 depends on the rotation speed of the blower 20 (the number of rotations of the fan of the blower 20 per unit time). Specifically, the higher the rotation speed of the blower 20, the higher the pressure generated by the blower 20, and the higher the speed of the air blown out from the air outlet 11. With such a configuration, in the present embodiment, air can be blown out as a jet flow from the slit-shaped air outlet 11. The velocity of the air during blowing is, for example, 80m/s or more.
The power unit case 21 is provided with a heater (not shown) for heating the high-pressure air generated by the blower 20. By using this heater, the air blown out from the air outlet 11 can be warmed.
The distance detection mechanism 30 detects a distance L1 between the nozzle portion 10 and the object BD disposed apart from the air outlet 11 in the air outlet direction D1. In the present embodiment, the blowing direction D1 is directed toward the inner surface 62s of the washbasin 62. Therefore, the object BD, which is disposed apart from the air outlet 11 in the air outlet direction D1, is, for example, the washbasin 62. In this case, the distance detection mechanism 30 detects the distance between the washbasin 62 and the nozzle unit 10. For example, when the drain port 65 is closed by the drain plug 67 of the wash basin 62 and water is accumulated in the wash basin 62, the object BD is water accumulated in the wash basin 62. In this case, the distance detection means 30 detects the distance between the water surface of the water accumulated in the wash basin 62 and the nozzle unit 10. As shown in fig. 3, the distance detection mechanism 30 is disposed near the air outlet 11 in the nozzle unit 10. As the distance detection means 30, for example, an optical distance sensor can be used. In the optical distance sensor, light emitted from a light source inside the distance sensor is reflected when it strikes the object BD, and is received by a light receiving element of the distance sensor. The distance is measured from the difference between the amount of light emitted from the light source and the amount of light received by the light receiving element.
The distance L1 detected by the distance detection means 30 will be described. As shown in fig. 1, in the present embodiment, the distance detection mechanism 30 detects a distance L1 along the blowing direction D1 between the object BD and the nozzle portion 10. That is, the distance L1 is correlated with the flow of air blown out from the air outlet 11 in the air-out direction D1. In general, when the air blown out from the air outlet 11 collides with the object BD at a high speed, water droplets adhering to the object BD are likely to be scattered. On the other hand, when the air blown out from the air outlet 11 collides with the object BD at a relatively slow speed, water droplets adhering to the object BD are less likely to be scattered. Further, as the air flows from the air outlet 11 in the air outlet direction D1, the speed of the air blown out from the air outlet 11 gradually decreases. Therefore, it is considered that when the air blown out from the air outlet 11 moves a certain distance from the air outlet 11 and the velocity sufficiently attenuates, the water droplets adhering to the object BD are not scattered even if the air collides with the object BD. From such a viewpoint, the distance L1 associated with the flow of the air blown out from the air outlet 11 is detected by the distance detection means 30.
Specifically, in the present embodiment, the distance between the air outlet 11 and the object BD in the nozzle portion 10 is set to the distance L1. That is, the distance L1 corresponds to the distance until the air blown out from the air outlet 11 in the air-out direction D1 moves from the air outlet 11 to collide with the object BD. Here, when the flow of the air blown out from the air outlet 11 is a jet, the blowing direction D1 coincides with the jet axis. When the distance L1 is short, the air blown out from the air outlet 11 collides with the object BD at a speed close to the speed at the time of blowing, and therefore water droplets adhering to the object BD are likely to be scattered. On the other hand, when the distance L1 is long, the air blown out from the air outlet 11 is attenuated before reaching the object BD and collides with the object BD at a speed slower than the speed at the time of blowing, and therefore, water droplets adhering to the object BD are less likely to be scattered.
When the distance between the outlet 11 of the nozzle section 10 and the object BD is set to the distance L1, it is preferable that the distance between the outlet 11 of the nozzle section 10 and the object BD is detected by the distance detection means 30. However, since there is substantially no large error, the distance between the portion of the nozzle section 10 near the discharge port 11 and the object BD may be treated as the distance between the discharge port 11 of the nozzle section 10 and the object BD. In the present embodiment, as described above, the distance detection means 30 is disposed near the air outlet 11 in the nozzle portion 10, and the distance between the object BD and the distance detection means 30 disposed near the air outlet 11 is used as the distance between the air outlet 11 and the object BD.
The hand detection mechanism 40 detects the presence or absence of a hand inserted between the nozzle portion 10 and the object BD disposed apart from the air outlet 11 in the air outlet direction D1. In the present embodiment, since the object BD is, for example, the wash basin 62 as described above, the hand detection mechanism 40 detects the presence or absence of a hand inserted between the wash basin 62 and the nozzle portion 10 in this case. When water is accumulated in the washbasin 62, the hand detection means 40 detects the presence or absence of a hand inserted between the water accumulated in the washbasin 62 and the nozzle section 10. As shown in fig. 3, the hand detection mechanism 40 is disposed near the air outlet 11 on the opposite side of the nozzle portion 10 from the distance detection mechanism 30. As the hand detection means 40, for example, an optical infrared sensor or a distance sensor can be used. In the infrared sensor, when infrared rays emitted from an infrared light emitting element are irradiated to a hand of a user, the infrared rays reflected by the hand are received by a light receiving element, and the hand is detected.
The control unit 50 sets the rotation speed of the blower 20 based on the distance L1 detected by the distance detection means 30, and drives the blower 20 when the hand detection means 40 detects a hand. In the present embodiment, as shown in fig. 1, the control unit 50 is provided inside the power unit case 21. Fig. 4 is a block diagram of a main part related to control of the hand drying device 1. As shown in fig. 4, the control unit 50 is communicably connected to each of the blower 20, the distance detection mechanism 30, and the hand detection mechanism 40, for example, by signal lines. The distance detection means 30 outputs a signal including information indicating the distance L1 detected by the distance detection means 30, and sends the signal to the control unit 50. The hand detection mechanism 40 outputs a signal including information indicating the presence or absence of a hand, and sends the signal to the control unit 50. The control unit 50 outputs a signal for controlling the operation of the blower 20 based on the signal output from the distance detection mechanism 30 and the signal output from the hand detection mechanism 40, and sends the signal to the blower 20. The blower 20 is operated in accordance with a signal output from the control unit 50, and blows air from the air outlet 11 of the nozzle unit 10.
In the present embodiment, as shown in fig. 4, the control unit 50 includes a distance determination unit 51, an operation control unit 52, and a storage unit 53. The distance determination unit 51 compares the distance L1 detected by the distance detection means 30 with a predetermined distance, and determines the magnitude relationship. The operation control unit 52 sets the rotation speed of the blower 20 based on the determination result of the distance determination unit 51. Further, the operation control unit 52 drives the blower 20 based on the detection result of the hand detection mechanism 40. The storage unit 53 stores a preset distance and a preset rotation speed. The respective units in the control unit 50 can communicate information with each other.
The control of the control unit 50 for setting the rotation speed of the blower 20 based on the distance detected by the distance detection means 30 will be described. In the present embodiment, the rotation speed of the blower 20 set by the control unit 50 has the following relationship: the rotation speed of blower 20 set when the distance detected by distance detection means 30 is less than the first distance is smaller than the rotation speed of blower 20 set when the distance detected by distance detection means 30 is the first distance.
As a specific example of setting the rotation speed of the blower 20, first, a preset distance and a preset rotation speed are stored in the storage unit 53. For example, the storage unit 53 stores a first distance as a preset distance, and stores a first rotation speed and a second rotation speed smaller than the first rotation speed as a preset rotation speed. Here, the first rotation speed is set to the rotation speed of the blower 20 as follows: when the distance L1 between the object BD and the nozzle portion 10 is the first distance, the velocity of the air sent out from the air blower 20 and blown out from the outlet 11 of the nozzle portion 10 is such that the water droplets adhering to the object BD are not scattered when the air collides with the object BD. The second rotation speed is set to the rotation speed of the blower 20 as follows: when the distance L1 between the object BD and the nozzle portion 10 is smaller than the first distance, the velocity of the air blown out from the air outlet 11 of the nozzle portion 10 is set to a velocity such that water droplets adhering to the object BD are not scattered when the air collides with the object BD. As an example of the velocity of a degree that does not scatter water droplets adhering to the object BD, when the velocity at which the air blown out from the air outlet 11 collides with the object BD is 20m/s or less, the air flow at this velocity does not have such a kinetic energy as to scatter water droplets adhering to the object BD, and therefore scattering of water droplets can be suppressed.
Upon receiving the signal output from the distance detection means 30, the distance determination unit 51 of the control unit 50 determines whether or not the distance L1 detected by the distance detection means 30 is equal to or greater than the first distance in the storage unit 53, and outputs the determination result to the operation control unit 52. When the distance determination unit 51 determines that the distance L1 detected by the distance detection means 30 is equal to or greater than the first distance, the operation control unit 52 sets the rotation speed of the blower 20 to the first rotation speed. When the distance determination unit 51 determines that the distance L1 detected by the distance detection means 30 is smaller than the first distance, the operation control unit 52 sets the rotation speed of the blower 20 to the second rotation speed.
Next, the drive control of the blower 20 by the control unit 50 based on the detection result of the hand detection mechanism 40 will be described. The hand detection mechanism 40 outputs a hand detection signal, which is a detection result of whether or not insertion of the user's hand between the object BD and the nozzle portion 10 is detected, to the control portion 50. For example, the hand detection means 40 outputs a high-level signal to the control unit 50 when a hand is detected, and outputs a low-level signal to the control unit 50 when a hand is not detected. When the hand detection signal received by the control unit 50 is a high-level signal, the operation control unit 52 determines that a hand is inserted between the object BD and the nozzle unit 10, and drives the blower 20 to rotate or maintains the rotation state of the blower 20. When the hand detection signal received by the control unit 50 is a low-level signal, the operation control unit 52 determines that a hand is not inserted between the object BD and the nozzle unit 10, and stops the blower 20 or maintains the state where the blower 20 is stopped.
In the present embodiment, as described above, the distance detection means 30 is disposed near the air outlet 11 in the nozzle portion 10, and the hand detection means 40 is disposed near the air outlet 11 on the opposite side from the distance detection means 30. That is, the distance detection mechanism 30 and the hand detection mechanism 40 are disposed close to each other. Therefore, if the control unit 50 performs the control related to the distance detection means 30 and the control related to the hand detection device 40 at the same time, there is a possibility that the distance detection means 30 recognizes the hand of the user detected by the hand detection device 40 as the object BD, detects the distance between the hand of the user and the nozzle portion 10, and the control unit 50 sets the rotation speed of the blower 20 based on the distance. Therefore, when the hand detection means 40 detects the hand of the user, the control unit 50 does not perform the operation of setting the rotation speed of the air blower 20 based on the distance L1 detected by the distance detection means 30, but sets the rotation speed of the air blower 20 based on the distance L1 detected by the distance detection means 30 when the hand detection means 40 does not detect the hand of the user.
The control unit 50 is realized as a processing circuit having a hardware configuration shown in fig. 5, for example. Fig. 5 is a diagram showing an example of a hardware configuration of the processing circuit. Each component constituting the control unit 50 is realized by, for example, the processor 71 shown in fig. 5 executing a program stored in the memory 72. In addition, the functions described above may be realized by cooperation of a plurality of processors and a plurality of memories. In addition, some of the functions of the control unit 50 may be implemented as electronic circuits, and the other may be implemented using the processor 71 and the memory 72.
Next, the operation of the hand dryer 1 of the present embodiment will be described with reference to fig. 6. Fig. 6 is a flowchart of the operation control of the hand dryer 1.
When the power of the hand drying device 1 is turned on, the hand drying device 1 is in a standby state. That is, blower 20 is stopped, and hand detection mechanism 40 is in a state where no hand is detected. First, in step S1, the distance detection mechanism 30 detects the distance L1 between the object BD and the nozzle portion 10, and outputs a signal including information indicating the detected distance L1 to the control portion 50.
Next, in step S2, the control unit 50 sets the rotation speed of the blower 20 based on the distance L1 detected by the distance detection means 30. More specifically, the distance determination unit 51 of the control unit 50 compares the distance L1 detected by the distance detection means 30 with a preset distance, and determines the magnitude relationship thereof. The operation control unit 52 sets the rotation speed of the blower 20 based on the determination result of the distance determination unit 51.
Next, in step S3, the hand detection mechanism 40 detects the presence or absence of a hand inserted between the object BD and the nozzle portion 10, and outputs a hand detection signal indicating the detection result to the control portion 50. In step S3, it is determined whether or not the hand of the user is inserted between the object BD and the nozzle portion 10. When the hand detection signal received by the control unit 50 from the hand detection mechanism 40 indicates that a hand is detected, this means that the hand of the user is inserted between the object BD and the nozzle unit 10. In this case, the control unit 50 proceeds to the process of step S4. When the hand detection signal received by the control unit 50 from the hand detection mechanism 40 indicates that no hand is detected, it means that the hand of the user is not inserted between the object BD and the nozzle unit 10. In this case, the control unit 50 proceeds to the process of step S7.
In step S4, the control unit 50 drives the blower 20 based on the detection result of the hand detection mechanism 40. More specifically, when the hand detection signal received from the hand detection mechanism 40 indicates that a hand is detected, the operation control unit 52 of the control unit 50 determines that a hand is inserted between the object BD and the nozzle unit 10, and rotates the air blower 20 at the rotation speed set in step S2. Accordingly, the air flows in from the intake port through the air filter provided in the power unit casing 21, is sent to the blower 20, and is pressurized by the blower 20. The air pressurized by the blower 20 reaches the nozzle portion 10 through the air duct 13, is accelerated at the outlet 11 of the nozzle portion 10, and is blown out from the outlet 11 as high-speed air. The air blown out from the air outlet 11 hits the hand of the user inserted between the object BD and the nozzle portion 10, and starts to blow off water adhering to the surface of the hand as water droplets.
Next, in step S5, the hand detection mechanism 40 detects the presence or absence of a hand inserted between the object BD and the nozzle portion 10, and outputs a hand detection signal indicating the detection result to the control portion 50. In step S5, it is determined whether or not the hand of the user inserted between the object BD and the nozzle portion 10 has been pulled out. When the hand detection signal received from the hand detection mechanism 40 indicates that a hand is detected, the control unit 50 repeats the process of step S5. In this case, since the hand of the user remains inserted between the object BD and the nozzle portion 10, the operation control portion 52 of the control portion 50 maintains the state in which the blower 20 is rotated. When the hand detection signal received from the hand detection mechanism 40 indicates that no hand is detected, the control unit 50 proceeds to the process of step S6.
When the hand detection signal received by the control unit 50 from the hand detection mechanism 40 indicates that no hand is detected, this means that the hand of the user inserted between the object BD and the nozzle unit 10 is pulled out. In step S6, the operation control unit 52 of the control unit 50 stops the rotating blower 20. Thereby, the air blown out from the air outlet 11 is stopped. Thereafter, the process returns to step S3.
In step S3, when the hand detection signal received by the control unit 50 from the hand detection mechanism 40 indicates that no hand is detected, the operation control unit 52 of the control unit 50 determines that a hand is not inserted between the object BD and the nozzle unit 10, and maintains the state in which the air blower 20 is stopped.
Next, in step S7, the control unit 50 determines whether or not a predetermined time has elapsed after the rotation speed of the blower 20 is set in step S2. If the set time has not elapsed, the process returns to step S3. When the set time has elapsed, the process returns to step S1 to update the rotation speed of blower 20 set in step S2. Accordingly, the rotation speed of the blower 20 can be reset in accordance with a change in the distance between the object BD and the nozzle portion 10, such as a case where water is accumulated in the wash basin 62.
As described above, the hand drying device 1 of the present embodiment includes: a nozzle section 10 provided with an outlet 11 that blows air in a preset blowing direction D1; a blower 20 that sends out air blown out from the air outlet 11 to the nozzle portion 10; a distance detection means 30 that detects a distance L1 between the nozzle portion 10 and an object BD disposed apart from the air outlet 11 in the air outlet direction D1; a hand detection device 40 that detects the presence or absence of a hand inserted between the object BD and the nozzle unit 10; and a control unit 50 that sets the rotation speed of the blower 20 based on the distance L1 detected by the distance detection means 30, and drives the blower 20 when the hand detection device 40 detects a hand. The rotation speed of blower 20 set when distance L1 detected by distance detection means 30 is smaller than the first distance is smaller than the rotation speed of blower 20 set when distance L1 detected by distance detection means 30 is the first distance.
With such a configuration, the rotation speed of the blower 20 when the blower 20 is driven when the hand detection mechanism 40 detects a hand is set based on the distance L1 detected by the distance detection mechanism 30. Therefore, the rotation speed of the air blower 20 can be changed according to the distance L1 between the object BD and the nozzle portion 10, and the speed of the air blown out from the air outlet 11 can be changed in accordance with the change. The rotation speed of the blower 20 set when the distance L1 is smaller than the first distance is smaller than the rotation speed of the blower 20 set when the distance L1 is the predetermined first distance. Accordingly, when the distance L1 is small, the speed of the air blown out from the air outlet 11 can be made low, and the speed when the air collides with the object BD can be made low, so that when the air blown out from the air outlet 11 directly collides with the object BD immediately after the hand inserted between the object BD and the nozzle portion 10 is pulled out, or the like, it is possible to prevent the water attached to the object BD from being scattered around by the air. Therefore, the user can be prevented from feeling uncomfortable and can use the sanitary towel.
Further, since the control unit 50 automatically sets the rotation speed of the air blower 20 based on the distance L1 detected by the distance detection means 30, it is possible to eliminate the task of setting the rotation speed of the air blower 20 in consideration of the depth of the sink 62 when an installer or a constructor who sets the hand drying device 1 on a sink or the like sets it. Even when the distance L1 changes, as in the case where water is accumulated in the wash basin 62, the control unit 50 automatically sets the rotation speed of the blower 20 based on the changed distance L1, and therefore, scattering of water accumulated in the wash basin 62 can be prevented.
The controller 50 sets the rotation speed of the blower 20 to a preset first rotation speed when the distance L1 detected by the distance detection means 30 is equal to or greater than a preset first distance, and sets the rotation speed of the blower 20 to a rotation speed less than the first rotation speed when the distance L1 detected by the distance detection means 30 is less than the first distance. With such a configuration, when the distance L1 detected by the distance detection means 30 is smaller than the first distance as a reference, the second rotation speed smaller than the first rotation speed is set, and therefore, when the distance L1 between the object BD and the nozzle portion 10 is shorter than a certain reference, such as when the depth of the wash basin 62 is shallow, for example, the rotation speed of the blower 20 can be automatically reduced, and water droplets adhering to the object BD can be made less likely to scatter.
The distance detection mechanism 30 is disposed near the air outlet 11 in the nozzle portion 10. With this configuration, the distance to the object BD can be easily detected with the nozzle section 10 as a reference. In particular, the distance between the air outlet 11 and the object BD in the nozzle portion 10 can be easily detected as the distance L1.
The commode 60 with hand dryer of the present embodiment includes: a water outlet unit 61 for discharging water; a wash basin 62 for receiving water discharged from the water outlet unit 61 from an inner surface 62 s; a nozzle unit 10 provided above the sink 62 and provided with an outlet 11 that blows air in a blowing direction D1 toward the inner surface 62s of the sink 62; a blower 20 that sends out air blown out from the air outlet 11 to the nozzle portion 10; a distance detection means 30 that detects a distance L1 between the nozzle portion 10 and an object BD disposed apart from the air outlet 11 in the air outlet direction D1; a hand detection mechanism 40 that detects the presence or absence of a hand inserted between the object BD and the nozzle unit 10; and a control unit 50 that sets the rotation speed of the blower 20 based on the distance L1 detected by the distance detection means 30, and drives the blower 20 when the hand detection means 40 detects a hand. The rotation speed of blower 20 set when distance L1 detected by distance detection means 30 is smaller than the first distance is smaller than the rotation speed of blower 20 set when distance L1 detected by distance detection means 30 is the first distance.
With such a configuration, the rotation speed of air blower 20 when air blower 20 is driven when hand detection device 40 detects a hand is set based on distance L1 between object BD and nozzle 10 detected by distance detection mechanism 30. Therefore, the rotation speed of the blower 20 can be changed according to the distance L1, and the speed of the air blown out from the air outlet 11 can be changed accordingly. The rotation speed of the blower 20 set when the distance L1 is smaller than the first distance is smaller than the rotation speed of the blower 20 set when the distance L1 is the predetermined first distance. Therefore, when the distance L1 is small, the speed of the air blown out from the air outlet 11 can be made low, and the speed when the air collides with the object BD can be made low, so that when the air blown out from the air outlet 11 directly collides with the object BD, it is possible to prevent the water adhering to the object BD from being scattered around by the air, and it is possible to avoid giving a sense of discomfort to the user. Further, since the control unit 50 automatically sets the rotation speed of the blower 20 based on the distance L1 detected by the distance detection means 30, it is possible to eliminate the need for an installer or the like to set the rotation speed of the blower 20 in consideration of the depth of the wash basin 62, and thus to achieve efficiency of the operation.
A control method of the hand dryer 1 according to the present embodiment is a control method of a hand dryer 1 including a nozzle portion 10 provided with an air outlet 11 that blows air in a preset blowing direction D1, a blower 20 that sends out the air blown out from the air outlet 11 to the nozzle portion 10, a distance detection mechanism 30, a hand detection device 40, and a control unit 50, the control method including: a step in which the distance detection means 30 detects a distance L1 between the nozzle portion 10 and the object BD disposed apart from the air outlet 11 in the air outlet direction D1; a step in which the control unit 50 sets the rotation speed of the blower 20 based on the distance L1 detected by the distance detection means 30; a step in which the hand detection device 40 detects the presence or absence of a hand inserted between the object BD and the nozzle unit 10; and a step in which the control unit 50 drives the blower 20 at a set rotation speed when the hand detection device 40 detects a hand. The rotation speed of blower 20 set when distance L1 detected by distance detection means 30 is smaller than the first distance is smaller than the rotation speed of blower 20 set when distance L1 detected by distance detection means 30 is the first distance.
Thus, when the hand detection mechanism 40 detects a hand, the blower 20 of the hand drying device 1 is driven at a rotation speed set based on the distance L1 between the object BD detected by the distance detection mechanism 30 and the nozzle portion 10. That is, the rotation speed of the blower 20 changes according to the distance L1 between the object BD and the nozzle portion 10, and the speed of the air blown out from the air outlet 11 changes accordingly. The rotation speed of the blower 20 set when the distance L1 is smaller than the first distance is smaller than the rotation speed of the blower 20 set when the distance L1 is the predetermined first distance. Therefore, when the distance L1 is small, for example, the speed at which the air blown out from the air outlet 11 collides with the object BD such as the washbasin 62 or the water accumulated in the washbasin 62 can be made slow, and therefore, when the air blown out from the air outlet 11 collides with the object BD, water droplets can be prevented from being scattered from the object BD by the air, and the user can be prevented from feeling uncomfortable.
In the above description, the control unit 50 compares the distance L1 detected by the distance detection means 30 with the first distance to set the rotation speed of the blower 20, but the rotation speed of the blower 20 may be set based on a table shown in fig. 7, for example. Fig. 7 is a table showing an example of the relationship between the distance L1 between the object BD and the nozzle portion 10 and the rotation speed of the blower 20. The table shown in fig. 7 is stored in advance in the storage unit 53 of the control unit 50. The control unit 50 sets the rotation speed of the blower 20 based on the distance L1 detected by the distance detection means 30, with reference to the table shown in fig. 7. For example, when the distance L1 is 200mm or more, the rotation speed of the blower 20 is set to a high rotation speed N1. When the distance L1 is 100mm or more and less than 200mm, the rotation speed of the blower 20 is set to the middle rotation speed N2. When the distance L1 is less than 100mm, the rotation speed of the blower 20 is set to a low rotation speed N3. The rotational speed N1 > the rotational speed N2 > the rotational speed N3. The rotation speed N1, the rotation speed N2, and the rotation speed N3 are set to the rotation speeds of the blower 20 as follows: according to the respective distances L1, when the air blown out from the air outlet 11 collides with the object BD, the velocity of the air is set to a velocity at which water droplets adhering to the object BD are not scattered.
Instead of the table shown in fig. 7, the rotation speed of blower 20 may be set based on the table shown in fig. 8. Fig. 8 is a table showing an example of the relationship between the dimensionless distance L0 and the rotation speed of the blower 20. Here, the dimensionless distance L0 is calculated by the equation (distance L1 — distance L2)/distance L2. As shown in fig. 1, the distance L2 is the distance in the blowing direction D1 between the edge 62r of the washbasin 62 and the nozzle section 10. More specifically, the distance L2 is the distance in the blowing direction D1 between the nozzle section 10 and the intersection of the virtual plane P1 including the upper end surface of the edge 62r of the washbasin 62 and the blowing direction D1. For example, the distance L2 is measured in advance and stored in the storage section 53 of the control section 50, and the control section 50 calculates the dimensionless distance L0 using the distance L1 detected by the distance detection mechanism 30 and the distance L2 stored in the storage section 53.
In this case, the control unit 50 calculates the dimensionless distance L0 based on the distance L1 detected by the distance detection means 30, and sets the rotation speed of the blower 20 with reference to the table shown in fig. 8. For example, when the dimensionless distance L0 calculated from the distance L1 is 1.0 or more, the rotation speed of the blower 20 is set to a high rotation speed N1. When the dimensionless distance L0 calculated from the distance L1 is 0.5 or more and less than 1.0, the rotation speed of the blower 20 is set to the middle rotation speed N2. When the dimensionless distance L0 calculated from the distance L1 is less than 0.5, the rotation speed of the blower 20 is set to the low rotation speed N3.
In the above description, the rotation speed of the blower 20 is set to a stepwise setting value with respect to the distance L1 detected by the distance detection means 30, but the present invention is not limited to this. The rotation speed of the blower 20 may be continuously set according to the distance L1. For example, the rotation speed of the blower 20 may be set to be smaller as the distance L1 detected by the distance detection means 30 becomes smaller. This also provides the same effects as those of the above-described configuration.
In the case of the above-mentioned distance L2, for example, in the case of a sink having the edge 62r of the sink 62 disposed below the upper surface of the counter part 63 and the edge 62r of the sink 62 covered with the peripheral edge of the opening of the counter part 63, the distance in the blowing direction D1 between the peripheral edge of the opening of the counter part 63 and the nozzle part 10 may be used as the distance L2 instead of the edge 62r of the sink 62. In this case, more specifically, the distance L2 is the distance in the blowing direction D1 between the nozzle portion 10 and the intersection of the virtual plane including the upper surface of the peripheral edge of the opening of the cabinet base portion 63 and the blowing direction D1.
Here, another example of the method for acquiring the distance L1 and the distance L2 will be described. Fig. 9 is a schematic side sectional view of another commode 60A according to the present embodiment. The main body 12A of the hand dryer 1A shown in fig. 9 is erected on the cabinet base 63, and is bent toward the washbasin 62 so as to extend obliquely upward. The blowing direction D1 shown in fig. 1 is substantially vertically downward, whereas the blowing direction D1A of the blowing port 11A of the nozzle portion 10A provided in the main body portion 12A is directed obliquely downward toward the inner surface 62s of the washbasin 62 as shown in fig. 9. In this case, a distance L1 between the object BD and the nozzle portion 10A along the blowing direction D1A is as shown in fig. 9. Fig. 9 shows a distance L2 in the blowing direction D1A between the edge 62r of the washbasin 62 and the nozzle portion 10A, which is used when the dimensionless distance L0 is calculated.
In the present embodiment, the air outlet 11 of the nozzle section 10 is formed in an elongated slit shape as described above. Therefore, the velocity core (potential core) of the air flow blown out from the outlet port 11 becomes small, and the velocity of the air flow tends to be attenuated as it becomes farther from the outlet port 11. This makes it possible to suppress the wind speed at which the air flow collides with the object BD after the user finishes drying the hand and extracts the hand while ensuring the wind speed sufficient to blow off the water droplets adhering to the hand at the position where the hand of the user is inserted. This makes it possible to make water droplets adhering to the object BD less likely to scatter, and to use the object more hygienically.
As described above, the hand detection means 40 is disposed near the air outlet 11 on the opposite side of the nozzle portion 10 from the detection means 30, and is disposed near the air outlet 11 on the side away from the water discharge portion 61 as shown in fig. 2. Since the main body 12 formed with the nozzle section 10 is arranged in parallel with the spout section 61, when the user moves his hand below the spout section 61 to wash his hand, the hand enters a portion below the nozzle section 10, and the hand detection mechanism 40 may detect the hand and blow out high-velocity air from the air outlet 11 of the nozzle section 10. In this case, since the water from the nozzle portion 61 is discharged simultaneously with the high-speed wind from the air outlet 11, the water discharged from the nozzle portion 61 may be scattered by the high-speed wind. As described above, by disposing the hand detecting device 40 at a position away from the spout portion 61 in the nozzle portion 10, it is possible to reduce the possibility that the hand of the user unintentionally enters the detection range of the hand detecting device 40, and it is possible to suppress simultaneous release of water and high-speed wind.
In the present embodiment, the blower 20 and the control unit 50 are provided inside the power unit casing 21, the power unit casing 21 is provided below the counter unit 63, and the main body 12 formed with the nozzle unit 10 is provided above the counter unit 63. By disposing the power unit case 21 that houses the blower 20 and the control unit 50 below the counter unit 63 in this manner, the space occupied by the hand dryer 1 on the counter unit 63 can be reduced, the space available to the user on the counter unit 63 can be enlarged, and the usability can be improved. Further, since the user cannot see the blower 20 and the like, the appearance can be improved.
Further, the configuration is not limited to the above, and for example, the nozzle portion 10 and the blower 20 may be provided in a single housing, and the housing may be provided above the counter portion 63. The control unit 50 is provided inside the power unit case 21, but may be provided outside the power unit case 21.
In the present embodiment, the spout unit 61 is configured to discharge water by a sensor that detects the hand of the user, but is not limited thereto. The water outlet unit 61 may be configured to discharge water by manual operation using a faucet lever or the like. The wash basin 62 is provided separately from the counter 63, but may be formed integrally with the counter 63. The shape of the washbasin 62 is not particularly limited as long as the water discharged from the water outlet unit 61 can be received by the inner surface 62 s.
The main body 12 of the hand dryer 1 is erected from the counter 63, but is not limited thereto. For example, the main body 12 may be supported by a wall WL and extend from the wall WL toward the washbasin 62.
The distance detection means 30 is an optical distance sensor, but is not limited to this, and other distance sensors may be used. The distance detection mechanism 30 is disposed in the nozzle portion 10, but is not limited thereto. The distance detection mechanism 30 may be provided separately from the nozzle unit 10 as long as it can detect the distance between the object BD and the nozzle unit 10. The distance detection mechanism 30 detects the distance L1 between the object BD and the nozzle unit 10, but the detection is not limited to direct detection, and indirect detection is also included. For example, the distance detection unit 30 may detect the distance L1 between the object BD and the nozzle unit 10 by detecting another distance and performing geometric transformation or the like based on the distance.
The hand detection means 40 is an infrared sensor or a distance sensor, but is not limited thereto. For example, an electrostatic capacitance sensor may be used as the hand detection mechanism 40. Further, the distance detection mechanism 30 and the hand detection mechanism 40 are provided separately, but not limited thereto. It is also possible that one sensor has both functions of the distance detection mechanism 30 and the hand detection mechanism 40. As such a sensor, for example, an optical distance sensor can be used. In this case, since the hand of the user is usually located near the nozzle portion 10 where the outlet 11 for blowing out the air is provided, for example, the distance sensor can distinguish between detection of the distance between the object BD and the nozzle portion 10 and detection of the hand by determining that the object detected within a predetermined distance range from the nozzle portion 10 is the hand and that the object detected at a position farther than the predetermined distance from the nozzle portion 10 is the object BD.
Embodiment mode 2
Embodiment 2 of the present invention will be described with reference to fig. 10. Fig. 10 is a bottom view of the nozzle portion 110 of the hand dryer 101 according to the present embodiment. In this embodiment, the same portions as those in embodiment 1 will not be described.
The nozzle portion 110 is provided with an outlet 111. Unlike the air outlet 11 formed in a slit shape in embodiment 1, in the present embodiment, as shown in fig. 10, the air outlet 111 has a structure in which a plurality of circular holes are arranged in a row. The circular holes are aligned in a row in the direction in which the distal end portion of the main body 12 extends. The diameter of each circular hole is set to, for example, 2mm or less. Further, in the nozzle portion 110, a hand detection mechanism 140 is disposed on the front end side of the air outlet 111. That is, the hand detection mechanism 140 is disposed on the side closer to the user in the nozzle unit 110. With this arrangement, the accuracy of hand detection by the hand detection means 140 can be improved, and the user can feel more comfortable.
The preferred embodiments of the present invention have been described above, but the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other changes in the structure can be made without departing from the spirit of the invention.
