FIG. 4 is a block diagram showing the configuration of the control circuit of the automatic hair washing machine 1. In FIG. 4, only the control elements characteristic of this embodiment are shown. The microcomputer 17 controls the automatic hair washing machine 1. On the control plate 7 described above, a power key 18 (instructing to turn on and off the power of the automatic hair washing machine 1), a temperature key 19 (setting a temperature of hot water mixed by the mixing valve 41), a temperature Display 20 (displays the temperature of hot water set with the temperature key 19), operation key 2
1 (instructing start / end of automatic hair washing operation), hot water supply key 22 (operated when hot water is stored in the hot water storage tank 45)
Etc. are provided. The signals of these respective keys are given to the microcomputer 17, and the display of the temperature indicator 20 is controlled by the microcomputer 17.

The temperature of the hot water detected by the thermistor 46 provided in the supply pipe 44 is the microcomputer 1
Given to 7. Further, when the hand shower cock 8 is twisted and hot water is jetted from the hand shower 4, the signal is given to the microcomputer 17. The microcomputer 17 is provided with a flag 32 and a timer 33 necessary for control described later.
The flag 32 and the timer 33 may be configured as software using RAM or the like, or may be provided as hardware.

The control signal of the microcomputer 17 is given to the motor 39, the mixing valve is operated by the motor 39, the valve (thermo valve) included in the mixing valve 41 is changed, and the mixing ratio of water and hot water is adjusted. To be done. 5 and 6 are flowcharts showing the control operation of the control circuit shown in FIG. 4, that is, the microcomputer 17. Hereinafter, the hot water supply temperature control in the automatic hair washer 1 will be described according to the flow of FIGS.

When the power key 18 is pressed, the microcomputer 17 turns on the power of the automatic hair washing machine 1 (steps S1 and S2). Further, the flag 32 is set (step S3). The flag 32 is necessary for determining whether or not the first hair washing operation or hot water supply after power-on, and is reset when the first hair washing operation is started after power-on or when hot water supply is started. (Step S described later
10). Next, temperature setting processing is performed (step S
4). The temperature setting process is a process of displacing the valve of the mixing valve 41 by the motor 39 so that hot water having the temperature set by the temperature key 19 is output from the mixing valve 41, and setting the mixing ratio of water and hot water. Is.
When the set temperature is changed by the temperature key 19, the motor 39 is driven accordingly and the temperature of the hot water output from the mixing valve 41 is adjusted.

Next, the microcomputer 17 determines whether the operation key 21 or the hot water supply key 22 has been pressed (step S5). When the operation key 21 is pressed to instruct operation, or the hot water supply key 22 is pressed to instruct hot water supply to the hot water storage tank 45, the timer 33 is started (step S6). Then, it is judged whether or not the set temperature by the temperature setting process performed in step S4 is in the range of 30 to 43 ° C (step S7). That is, the temperature of the hot water set by the temperature key 19 is 30 to 4
It is determined whether the temperature is within the range of 3 ° C. If it is not within this range, the microcomputer 17 drives the motor 39,
Set the temperature of the hot water output from the mixing valve 41 to 39
The temperature is forcibly changed to ° C (step S8).

That is, when the operation key 21 is pressed to start the automatic hair washing operation, or when the hot water supply key 22 is pressed to start supplying hot water to the hot water storage tank 45, the temperature of the hot water stored in the hot water storage tank 45 Is controlled to fall within the range of 30 to 43 ° C. If the temperature of the hot water stored in the hot water storage tank 45 is lower than 30 ° C., the person to be washed feels cold when washing the hair with the hot water. On the other hand, if the temperature of the hot water stored in the hot water storage tank 45 exceeds 43 ° C,
It is too hot for hot water used for washing hair. Therefore, as described above, the temperature of the hot water stored in the hot water storage tank 45 is controlled to fall within an appropriate temperature range.

Next, it is judged whether or not the flag 32 is set (step S9), and if it is set, the flag is reset (step S10) and the timer 33 is set.
It waits until 60 seconds have elapsed (step S11). On the other hand, if the flag 32 has already been reset, it waits until the time measured by the timer 33 has passed 20 seconds (step S16). When the time measured by the timer 33 exceeds 60 seconds or 20 seconds, the temperature difference between the hot water temperature B detected by the thermistor 46 and the hot water temperature A set by the temperature key 19 is It is determined whether or not the temperature exceeds 1 ° C. (step S12).

When the flag 32 is set, it means that the hair washing operation or the hot water supply is performed for the first time after the power is turned on, until the temperature of the water or the hot water flowing into the mixing valve 41 from the external water supply equipment or the hot water supply equipment becomes stable. It seems that it takes a relatively long time. Therefore, in such a case, the temperature detected by the thermistor 46 is not referred to for 60 seconds after the hot water supply is started, and when the temperature exceeds 60 seconds, the thermistor 46
It was decided to compare the temperature B detected in step A with the set temperature A.

On the other hand, when the automatic hair washing machine 1 is installed in, for example, a beauty salon, it is operated intermittently during business hours, but the mixing valve 41 outputs the power even when the operation starts or the hot water supply starts. A waiting time of about 20 seconds is set until the temperature of the hot water to be stabilized becomes stable (step S
16). Then, after that, it was decided to compare the temperature B detected by the thermistor 46 with the set temperature A. By setting such a waiting time, the temperature correction processing is performed after the detected temperature of the thermistor 46 is stabilized,
The device can be highly reliable.

The temperatures are compared in step S12, and it is further determined whether or not | AB | exceeds 1 ° C. for 10 seconds or more (step S13). Then, when it continues for 10 seconds or more, the motor 39 is driven and the mixing valve 41 is adjusted so that the temperature difference A-B becomes 1 ° C. or less (step S14). As a result, the effects of overshoot and undershoot in which the temperature of the hot water output from the mixing valve 41 temporarily rises or falls can be ignored.

By the above control, the mixing is performed regardless of the difference in water temperature or hot water temperature which changes with the season, the water pressure from the external water supply equipment or the hot water supply equipment connected to the automatic hair washing machine 1 or the difference in boiler capacity. The temperature of the hot water output from the valve 41 is always automatically controlled to a desired temperature, and hot water having a comfortable temperature for washing hair can be obtained. The temperature correction in step S14 is preferably performed within a range of ± 4 ° C with respect to the set temperature. This is because if the temperature difference between the set temperature A and the detected temperature B does not fall below 1 ° C. even if the correction is performed within this range, the thermo valve of the mixing valve 41 may be defective.

After the temperature setting process is performed in step S4,
When the operation key 21 or the hot water supply key 22 is not pressed and the hand shower cock 8 is twisted and hot water is jetted from the hand shower 4 (YES in step S17), the timer 33 is started (step S18), and the time count thereof is started. Is waited for more than 30 seconds (step S19), and correction control is performed so that the temperature of the hot water injected from the hand shower 4 reaches the set temperature (steps S12 to 14).

In this way, the hot water sprayed from the hand shower 4 is also controlled so that the hot water temperature becomes appropriate. Since the hot water sprayed from the hand shower 4 is manually operated by the operator, the set temperature range is not limited to 30 to 43 ° C., and may be higher or lower than that. When the hand shower cock 8 is not opened in step S17, the microcomputer 17 waits for other processing (step S20).

The 60 seconds in step S11, the 20 seconds in step S16, and the 30 seconds in step S19 are examples of time, and may be set to other set seconds. In addition, 30 to 4 defined here
The temperature range of 3 ° C is an example, and is, for example, 35 to 42 ° C.
The range may be any temperature range that is considered appropriate for automatic hair washing. In addition, 39 in step S8
C. is also an example, and it may of course be changed to 40.degree. C. or the like.

When the automatic hair washer 1 is turned on,
The process from step S4 is repeated. When the business hours of the beauty salon are reached and the power key 18 is pressed again (YES in step S15), it is determined whether the hot water temperature set by the temperature key 19 is 30 to 43 ° C. (step S21). ). If it is not within this range, the set temperature is forcibly changed to 39 ° C. (step S22), and then the power is turned off (step S23). In other words, when the hot water temperature is set outside the temperature range suitable for automatic hair washing, the temperature is forcibly returned to 39 ° C, which is the appropriate temperature before turning off the power, and when the power is turned on next time, it becomes unexpectedly hot. It prevents hot water and cold water from coming out.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims.
