The hot water once drained to the drain pipe 56 flows back into the drain pan 55, so that the drain pan 5
5 is provided with a water level sensor 54 for detecting an abnormal state in which hot water is full. An outlet pipe 57 is connected below the hot water storage tank 45. The other end of the outflow pipe 57 is connected to a suction port of a pump 59. An inverter 58 is connected to the pump 59, and the pump 59 is driven by supplying an alternating current from the inverter 58. When the pump 59 is driven, the hot water stored in the hot water storage tank 45 is sucked into the pump 59 through the outflow pipe 57.

The upper nozzle link 23 and the lower nozzle link 25 are oscillated and rotated by a drive mechanism 28 during hair washing. As a result, the jetting direction of the hot water jetted from the upper nozzle 24 and the lower nozzle 26 is changed, whereby the hair of the person to be hair-washed can be washed uniformly and well. FIG. 3 is a schematic configuration diagram of a drive mechanism of the automatic hair washer of FIG.

In the drive mechanism 28, the upper nozzle link 23 and the lower nozzle link 25 are connected to one link motor RM.
Drive-coupled. That is, a relatively short arm 32 is attached to the rotation shaft 31 of the link motor RM. One end of a link bar 33 is rotatably connected to the tip of the arm 32, and the other end of the link bar 33 is rotatably supported by a protruding shaft 35 provided on a pulley 34 of the lower nozzle link 25. . The pulley 34 of the lower nozzle link 25 and the pulley 36 of the upper nozzle link 23 are connected via an endless belt 37. The belt 37 crosses between the pulley 34 and the pulley 36, and the pulley 3
The pulley 4 and the pulley 36 are rotated in opposite directions.

When the link motor RM rotates, the arm 3
2 rotates, and the rotational force is converted into a vertical movement of the link rod 33. The vertical movement of the link rod 33 causes the pulley 34 to reciprocate within the range of the fixed angle D2, and accordingly, the lower nozzle link 25 also reciprocates within the angle range D2. In addition, the above-described reciprocating rotational movement of the pulley 34 of the lower nozzle link 25 is transmitted to the pulley 36 via the belt 37, so that the upper nozzle link 23 is also swung within the range of the fixed angle D1.

With this structure, the upper nozzle link 23 and the lower nozzle link 25 reciprocate between the following nozzle positions, and the upper nozzle link 23 and the lower nozzle link 25 are interlocked with each other, and are the same. It is arranged at the nozzle position. The nozzle position is set at three positions: an upper position, a horizontal position, and a lower position. In the upper position, the upper nozzle link 23 is located diagonally above the head, and washing water is jetted diagonally downward from the upper nozzle 24 (illustrated as A3 in FIG. 1). At this time, the lower nozzle 26
Is sprayed toward the neck.
In the lower position, the upper nozzle link 23 is obliquely below the head, and the washing water is jetted obliquely upward from the upper nozzle 24 (illustrated by A1 in FIG. 1). Further, the cleaning water sprayed from the lower nozzle 26 is sprayed toward the tip of the head.
The horizontal position is located substantially in the middle between the upper position and the lower position, and the upper nozzle link 23 has an arc-shaped central portion located at substantially the same height as the height position of the rotating shaft (shown by A2 in FIG. 1). ).

A first reed switch 91 for detecting the lower position and a second reed switch 92 for detecting the horizontal position
Are provided. The first reed switch 91 and the second reed switch 92 are switches that output signals in response to the magnetism of the magnet 38 fixed to the end face of the pulley 34, for example. The second reed switch 92 is disposed so as to face the magnet 38 on the pulley 34 in the horizontal position. Further, the first reed switch 91 is disposed so as to face the magnet on the pulley 34 in the state where the first reed switch is in the lower position (this state is shown in FIG. 3).

The drive mechanism 28 is controlled by the control unit 17 based on the signal outputs of these two reed switches. FIG. 4 is a block diagram of a main part of an electrical configuration of the automatic hair washer of FIG. The control unit 17 includes a microcomputer (CPU) as a control center and an RA as storage means.
M, ROM, etc. The CPU controls each unit based on a program stored in the ROM or the like in advance, the contents of a flag set in the RAM, and the like. Further, the CPU includes a timer 17a as time measuring means.
By measuring the elapsed time, the drive time of the link motor RM can be controlled.

A second reed switch 92 and a first reed switch 91 are connected to the microcomputer. A link motor RM is connected to the microcomputer, and the microcomputer can be driven in a predetermined rotation direction, for example, clockwise in a predetermined operation mode. A pump 59 is connected to the microcomputer via an inverter 58, and the frequency of the pump 59 can be changed via the inverter 58 to change the water pressure discharged from the pump 59.

Further, a flag F for setting the frequency of the commercial AC power supplied as power is set in the RAM. When the flag F is "1", the frequency is 50
Hz. This is because the frequency of the commercial AC power supply may be different depending on the region, and if the frequency is different, the rotation speed differs depending on the motor. Next, the operation of the automatic hair washer 1 will be described.

First, in the automatic hair washing machine 1, the following processing is performed prior to the hair washing operation. That is, hot water is supplied into hot water storage tank 45 as described above. Further, when the link motor RM is driven to displace the upper nozzle link 23 and the lower nozzle link 25 to the horizontal position and the second reed switch 92 is turned on, the driving of the link motor RM is stopped. When the hot water supply is completed, the key switch 16
Is waiting for an input operation. Normally, the head of the person to be washed is inserted into the water tank 13 in this state. Then, when a hair washing start signal is input from the key switch 16, the following hair washing operation is started.

An outline of the hair washing operation will be described in advance. First, an initial drainage process is performed. Here, the cold water accumulated in the outflow pipe 57, the branch pipe 75, and the pipes 80, 81, 82, 83 is drained. Next, a weak cleaning step is performed. Here, while warming the hair of the person being washed with warm water,
Removes dust etc. from hair. Next, a main washing step in which the warm water mixed with the shampoo solution is sprayed to the person to be washed, a first rinsing step for dropping the shampoo liquid from the hair of the person to be washed after the main washing step, and a warm water mixed with the treatment liquid. Is sprayed to the person to be washed, and a second rinsing step for dropping the treatment liquid from the hair of the person to be washed after the treatment step is performed in order, whereby the hair washing is completed.

Since the features of the present invention are shown in the operation of the upper nozzle link 23 from the initial drainage stroke to the weak washing stroke, these strokes will be mainly described. In the initial drain stroke, the upper nozzle link 23 is moved from the horizontal position to the lower position. Then, the pump is stopped at the lower position, and the pump 59 is driven at a low frequency for a predetermined time, and the washing water slowly flows out from each nozzle. Thereby, the cold water in the pipe is discharged so as not to hit the head.

Next, the next weak cleaning step will be described with reference to the flowchart of FIG. In this weak cleaning process,
The driving of the link motor RM is restarted in a predetermined direction, for example, clockwise (step S1). Next, step S
In 2, it is determined whether or not the nozzle position is at the lower position based on the output signal of the first reed switch 91. At the start of the weak cleaning process, the nozzle position is at the lower position (YES in step S2), so that the timer 17a starts measuring time immediately (step S3). Thereafter, with the drive of the link motor RM, each nozzle link starts displacing from the lower position toward the horizontal position.

In step S4, it is determined whether or not the nozzle position is a horizontal position based on the output signal of the second reed switch 92. When the nozzle position becomes the horizontal position (YES in step S4), the next AC power supply frequency determination processing is performed. In step S5, the time measurement result by the timer 17a is read, and the time measurement result is determined. That is, the timing result is within a predetermined time range, for example,
If 1.55 seconds to 1.85 seconds (YE in step S5)
S), it can be determined that the AC power supply frequency is 50 Hz, and the flag F is set to "1" (step S6). If the time measurement result is shorter than this (NO in step S5), the flag F remains at “0” and the AC power
Hz is set.

Here, the above-mentioned predetermined time range is set as a time taken from the lower position to the horizontal position when the link motor RM, which is an AC motor, is driven by an AC power supply of 50 Hz. The range is set in consideration of the difference between the ranges. That is, for example, if the rotation speed of the AC motor is different according to the AC power supply frequency,
This is because the position after the displacement is different even if the driving time is the same.

During this time, the driving of the link motor RM is continued. In step S7, the AC power supply frequency is determined based on the content of the flag F, and the drive mechanism 28 is controlled as follows. That is, if the AC power supply frequency is 5
In the case of 0 Hz (YES in step S7), the link motor RM is driven for a predetermined first drive time T1, for example, 3.6 seconds, and when this drive time T1 elapses,
The drive of the link motor RM is stopped (step S
8). If the AC power supply frequency is 60 Hz (NO in step S7), the predetermined second drive time T2,
For example, the link motor RM is driven for 3.0 seconds, and when the drive time T2 has elapsed, the drive of the link motor RM is stopped (step S9). The driving time here is
The nozzle position is the elapsed time from the lower position (step S3). The first drive time T1 is equal to the length of the link motor RM.
Is set as the time from the lower position to the upper position when driven by an AC power supply of 50 Hz. The second drive time T2 is set as the time from the lower position to the upper position when the link motor RM is driven by an AC power supply of 60 Hz. Thereby, it is possible to prevent a positioning error of the upper position caused by the AC power supply frequency.

When the nozzle position is considered to have reached the upper position by being driven during the drive time, the drive of the link motor RM is stopped. Then, at this position, the pump 59 is driven and hot water is sprayed on the hair. The stop at this position is performed for a predetermined time T3 after the start of the weak cleaning process, for example,
It is maintained until 16 seconds have elapsed. As a result, warm water is sufficiently sprayed onto the head and hair of the person to be washed, and the head and hair are sufficiently wetted, so that entanglement of the hair can be prevented in the subsequent process of washing the hair.

After a lapse of 16 seconds, the link motor RM is driven clockwise again (step S10). Thereafter, until a predetermined time T4 for the weak cleaning process elapses (Step S
(NO at 12), while each nozzle link reciprocates between the upper position and the lower position, hot water is sprayed from each nozzle, and at the same time, hot water is replenished into the hot water storage tank 45 to perform a hot water supply process (step). S11). After a lapse of a predetermined time, the above-described main washing process is started.

As described above, according to the present embodiment, the driving when the lower position is set as the starting point based on the displacement time for displacing between the lower position as the first position and the horizontal position as the second position. By determining the time T1 or the drive time T2 and controlling the drive mechanism 28 by the drive time, the upper nozzle link 23 can be displaced from the starting point and stopped at the upper position as the third position. As described above, when the upper nozzle link 23 is stopped at the upper position, the position detection switch corresponding to the upper position can be omitted, so that the configuration for control can be simplified.

Moreover, since only two position switches for a fine hair washing operation can be used, it can be easily mounted, and the structure of the upper nozzle link 23, in particular, the drive mechanism 28 thereof can be simplified. Further, since there is no need to provide a switch for setting the AC power supply frequency for switching the driving time, the configuration for control can be further simplified.

Further, by setting the position where the position detecting switch is not provided as the upper position where the hair is stopped to wet the hair at the start of the hair washing, an increase in control load after the start of the hair washing can be suppressed. Further, the first position and the second position, which are positions for determining the driving time, are defined as a horizontal position, which is a stop position until the start of operation, and the first position is a first stop after displacement from the horizontal position. By setting the lower position, which is the position, the first to third positions can be sequentially arranged vertically, and according to the operation of the upper nozzle link 23 before the hair washing operation,
The operation can be performed with the drive time determined, and unnecessary displacement of the upper nozzle link 23 can be avoided.

By setting the upper position to be stopped without the position detecting switch as the dead center of the reciprocating displacement of the drive mechanism 28, the displacement speed decreases near this dead center, so that the driving time is increased. Even if the stop of the position is controlled, accurate positioning can be achieved. Further, since only two lead sensors are required for positioning the horizontal position, the lower position, and the upper position, the cost can be reduced.

In the above embodiment, the horizontal position and the lower position are detected by the reed switch, and the upper position is not detected. However, the present invention is not limited to this. In short, it is only necessary to be configured to be able to stop at the third position based on the drive time determined between the first position and the second position where the switch is provided. Further, it may be configured such that the switch is driven and controlled for a drive time so as to stop from a certain predetermined position of the switch to a stop position different from the predetermined position.

Various other design changes can be made without departing from the spirit of the present invention.

[0053]

According to the first aspect of the present invention, the following effects can be obtained. That is, by determining the drive time to the third position based on the displacement time between the first position and the second position, the nozzle link can be stopped at the third position, and the nozzle link can be stopped at the third position. The position switch to be used can be omitted, and the configuration for control can be simplified.

According to the second aspect of the present invention, the following effects are obtained in addition to the effects of the first aspect of the present invention. That is, by setting different drive times according to the AC power supply frequency by the setting means, it is possible to prevent a positioning error of the third position due to the AC power supply frequency. As a result, there is no need to provide a switch or the like for switching the drive time depending on the AC power supply frequency, so that the configuration for control can be further simplified.

According to the third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, the position where the hair is stopped to wet the hair at the start of the hair washing is set to the third position, so that the hair While preventing entanglement, it is possible to suppress an increase in control load after the start of hair washing.

That is, the nozzle link that swings along the head can be stopped at the first to third positions, and a fine hair washing operation can be performed.

According to the invention described in claim 6, the reciprocating drive means is driven for a predetermined time after the detection of the predetermined position by the position switch, whereby the reciprocating drive means can be stopped at a predetermined position, without providing a position switch for this purpose. As a result, the configuration for control can be simplified.
