FIG. 5 is a flowchart showing a water level control process of the hot water storage tank 26 during the hair washing process in the automatic hair washer according to this embodiment. First, how the amount of hot water in the hot water storage tank 26 is controlled during the hair washing process will be described along the flow of FIG.

As an initial operation, after the supply of hot water to the hot water storage tank 26 is completed and the hair can be washed, the start button 19 of the operation panel 10 is pressed. Thereby, the hair washing process starts. When the hair washing process starts,
The microcomputer 71 detects the amount of water in the hot water storage tank 26 based on the outputs of the lower water amount sensor 30, the middle water amount sensor 31, and the upper water amount sensor 32.

If the hot water in the hot water storage tank 26 is between the upper level and the middle level (NO in step S1), it is determined whether the hair washing time has elapsed (step S2). If the shampooing time has not elapsed, the process waits until the water level of the hot water in the hot water storage tank 26 becomes equal to or less than the water level detected by the medium water level sensor 31. When the amount of hot water in the hot water storage tank 26 becomes equal to or less than the water amount detected by the middle water amount sensor 31, the hot water storage valve 24 is opened (step S3), and the supply of hot water from the mixing valve 22 to the hot water storage tank 26 starts. Is performed (step S3). Then, it is determined whether or not the water level in the hot water storage tank 26 is detected by the upper water level sensor 32 (step S4), and if not, it is further determined whether or not the hair washing time has elapsed (step S5). When the water level in the hot water storage tank 26 reaches the water amount detected by the upper water amount sensor 32 within the hair washing time (YE in step S4).
S), the hot water storage valve 24 is closed (step S6).

Thereafter, the same control is repeated. If the hair washing time has elapsed in step S5, the hot water storage valve 24 is immediately turned off (step S5).
7), the control of supplying hot water to the hot water storage tank 26 ends.
At the same time, the hair washing ends. FIG. 6 is a flowchart showing a control operation when draining is performed in the automatic hair washer.

Next, the drainage control will be described mainly with reference to FIG. When this automatic hair washer is installed in, for example, a beauty salon, a drain button 20 provided on the operation panel 10 at the end of a business day.
(See FIG. 1) is pressed. When the drain button 20 of the operation panel 10 is pressed, a tank drain key-on signal is given to the microcomputer 71 from the corresponding key switch (see FIG. 4) (step S10).

When the drain key-on signal is given, the microcomputer 71 detects the state of the hood switch 17 (step S11). If the hood switch 17 is turned on, that is, if the hood 4 is closed, then the water level of the hot water storage tank 26 is determined (step S12). As a result of the water level determination, if there is an output of the lower water quantity sensor 32 and the water level is equal to or higher than the lowest water level,
When the pump 39 is turned on, the drainage electromagnetic valve 4
5 is turned on to perform drainage control (step S1).
3). In the drainage control, the remaining water in the hot water storage tank 26
8, pump 39, branch pipe 41, electromagnetic valve 45 for drainage,
The water is sprayed from the top nozzle 8 into the water tank 3 through the fourth supply pipe 49 and the supply path 55 with a predetermined force. The water is also drained to a drain trap 56 via a water pipe 57. This drainage is performed until the remaining water in the hot water storage tank 26 falls below the water level detected by the lower water quantity sensor 30 (step S1).
4).

When the remaining water in the hot water storage tank 26 becomes equal to or less than that detected by the lower water amount sensor 30, that is, when the remaining water in the hot water storage tank 26 is almost exhausted, the drive of the pump 39 is turned off, and , Drainage solenoid valve 4
5 is closed. In the above step S13, the operation rate of the pump 39 is adjusted by the inverter 40 so that the injection amount of the residual water injected from the top nozzle 8 becomes a desired injection amount, in other words, an injection amount suitable for cleaning the water tank 3. Controlled. Thereby, the water tank 3 can be favorably washed using the residual water.

In the drainage control shown in FIG. 6, the drainage electromagnetic valve 45 is opened at the time of drainage, so that the residual water remaining in the hot water storage tank 26 is injected from the top nozzle 8 and used for washing the water tank 3 and drainage. The water is also drained directly to the trap 56. Providing the water pipe 57 in this way and discharging a part of the residual water directly to the drain trap 56 has an advantage that the residual water in the hot water storage tank 26 can be drained in a short time.

Instead of such a configuration, the water channel 57 may be eliminated, and all the remaining water may be jetted from the top nozzle 8 so that the water tank 3 is washed with all the remaining water simultaneously with the drainage. In the above embodiment, the configuration in which the top nozzle 8 is specially provided in the hood 4 and the supply path 55 for supplying water to the top nozzle 8 is described.

However, a configuration in which such a top nozzle 8 and the supply path 55 are not provided may be adopted. In such a case, when draining residual water in the hot water storage tank 26, the pump 39 is driven, and the top electromagnetic valve 42, the neck electromagnetic valve 43, and the long electromagnetic valve 44 are opened. As a result, the residual water in the hot water storage tank 26 is
And drained from 54. Nozzles 52, 5
As a result, the residual water is injected from the
Can be washed. In this case, it is preferable that the driving device 53 be driven so that the head nozzle link 50 and the collar nozzle link 51 are oriented in a predetermined direction. The predetermined direction is a direction in which the jetted water does not scatter from the cutout 5 formed in the hood 4.
Further, it is preferable that the operation rate of the pump 39 is set so that the injection amount from the nozzles 52, 52 becomes an injection amount suitable for cleaning.

The nozzle 5 provided in the water tank 3 as described above
By injecting residual water from 2, 54, the water tank 3 can be washed at the same time as drainage. In this case, cleaning can be performed without requiring a special additional configuration for cleaning. At the time of washing, a hood cover (see Japanese Patent Application No. 5-14094) proposed by the present applicant is attached to the cutout portion of the hood 4 so that the washing water flows from the cutout portion 5 of the hood 4 to the outside. It is preferable because it can be prevented from scattering.

[0037]

According to the first aspect of the present invention, the water tank can be washed by using the residual water in the hot water storage tank, so that the residual water can be used effectively. In particular, when cleaning the inside of the water tank using the residual water, the water tank can be cleaned at the same time as the drainage without newly adding a cleaning component in addition to the conventional structure.

According to the second aspect of the present invention, the washing can be performed while draining the remaining water in the hot water storage tank only when the hood provided at the top of the water tank so as to be openable and closable is closed. Therefore, it is possible to prevent the washing water from splashing out of the machine due to the opening of the hood. In the invention according to claim 3,
Since the hood is provided with a dedicated nozzle for cleaning when draining residual water, cleaning using residual water can be performed more favorably.
