DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic hair washer, and more particularly, to a business-use automatic hair washer used in a beauty salon or the like.

[0002]

2. Description of the Related Art Conventionally, there has been proposed an automatic hair washer for automatically washing hair of a person to be washed according to a hair washing course without manual intervention. This automatic hair washer has a hot water storage tank for storing hot water used for hair washing, a pump for drawing out the hot water stored in the hot water storage tank, an outflow pipe connecting the hot water storage tank and a suction side of the pump, A nozzle link that is connected to the discharge side of the pump and has a plurality of nozzles that can inject hot water. The hot water stored in the hot water storage tank is pumped out through an outflow pipe by a pump and is given to each nozzle of the nozzle link. Then, the hair of the person to be washed is automatically washed by vigorously jetting warm water from the nozzle.

[0003] The hair washing course set in the automatic hair washing machine includes a so-called initial drainage step of draining cold water accumulated in an outflow pipe, a pump, a nozzle link, and the like before actual hair washing is started. I have. In the initial drainage process,
For example, the pump is driven with a relatively low driving force for about 26 seconds. As a result, the cold water accumulated in the outlet pipe or the like is jetted from the nozzle with a relatively weak jetting force. Thereby, the cold water can be drained without applying the cold water to the hair of the person to be washed.

[0004]

However, in the above automatic hair washer, there are cases where the cold water accumulated in the outflow pipe or the like cannot be sufficiently drained even if the initial drainage process is performed. In this case, in the hair washing process performed immediately after the initial drainage process, cold water is swiftly jetted to the person to be washed, causing a problem that the person to be washed is uncomfortable.

[0005] In particular, when the automatic hair washer is installed in a place where it is easily exposed to the outside air or when it is used in winter, the temperature of the cold water accumulated in the outflow pipe and the like is relatively low, so the above-mentioned disadvantages are remarkable. become.

To cope with this, it is conceivable to extend the execution time of the initial drainage stroke, for example. However, in this case, the whole hair washing time becomes longer, which is not preferable. Moreover, the initial drainage process is even more unrelated to the actual hair washing process.

An object of the present invention is to solve the above-mentioned technical problems and to provide an automatic hair washer capable of reliably draining cold water accumulated in an outflow pipe or the like without prolonging the hair washing time. .

[0008]

Means for Solving the Problems and Embodiments of the Invention In order to achieve the above object, an automatic hair washer according to claim 1 is provided.
A hot water storage tank for storing hot water used for hair washing, a hot water injection nozzle, a pump for drawing out hot water stored in the hot water storage tank and supplying the hot water to the hot water injection nozzle, and A start key for instructing to automatically wash hair, and a drain key for manually instructing execution of a process of discharging water accumulated in a path leading to the hot water injection nozzle through the hot water injection nozzle. When the start key is operated, the pump is driven according to a hair washing course to perform hair washing, and when the drain key is operated when the start key is not operated, the A pump that is driven and includes a microcomputer that executes a process of draining water accumulated in a path leading to the hot water injection nozzle. .

According to a second aspect of the present invention, in the automatic hair washer according to the first aspect, when the drain key is operated, the microcomputer controls the pump according to a predetermined condition. It is characterized by being driven.

According to a third aspect of the present invention, there is provided the automatic hair washer according to the first aspect, wherein the microcomputer is configured to execute the operation when the start key is not operated, and During the hot water supply or after the completion of the hot water supply, the operation of the draining key is received.

[0011] In the automatic hair washer according to these inventions, when the hair draining key is operated while the hair is not being washed, the pump is driven according to predetermined conditions.
Thereby, the cooled water accumulated in the path from the hot water storage tank to the hot water injection nozzle can be discharged through the nozzle. Therefore, for example, if the drain key is operated before the hair washing is started, the cold water accumulated in the above-mentioned path can be drained in advance. Therefore, the hair washing time does not become longer due to the cold water drainage.

In addition, if an instruction for initial drainage is given, for example, before the hair-washing person is ready to wash the hair, a hairdresser or the like checks the temperature of the drained water by hand or the like before starting the hair-washing. Therefore, drainage can be reliably performed without leaving cold water.

FIG. 4 is a block diagram showing a configuration of an electric control circuit of the automatic hair washer. The control circuit includes a microcomputer 200 as a control center. The microcomputer 200 receives signals from various switches and sensors. Microcomputer 2
At 00, control signals are output to various elements and devices based on the given signals.

Specifically, in response to pressing of various keys provided on the operation panel 7 (see FIG. 2), various set values and the like are given to the microcomputer 200 from the corresponding key switches 201. A thermistor 77 for detecting the temperature supplied to the hot water storage tank 76;

Further, by giving a control signal to the link motor RM, the swing and rotation of the upper nozzle link 61 and the lower nozzle link 63 are controlled respectively. The microcomputer 200 further controls the pump 91 to operate at a predetermined power by controlling the inverter 90.

FIG. 5 is a flowchart for explaining a manual initial drainage process in the automatic hair washer. This manual initial drainage treatment is performed by the outlet pipe 89, the branch pipe 100, the first
In order to drain cold water accumulated in the supply pipe 105, the second supply pipe 106, the third supply pipe 107 and the fourth supply pipe 108, the upper nozzle link 61, the lower nozzle link 63, and the like,
It is executed by an operation of a hairdresser or the like.

Here, prior to a more detailed description of the manual initial drainage treatment, first, the change of the operation mode of the automatic hair washer will be briefly described. The operation mode of the automatic hair washer
When the power switch 13 is turned on, the mode shifts to the standby mode. In this standby mode, when the hot water supply key 21 is pressed by a beautician or the like, the mode shifts to a hot water supply mode in which hot water is supplied to the hot water storage tank 76. At the same time, drain key 4
The operation shifts to the initial drain standby mode in which the operation 9 is accepted. Thereafter, when the hot water supply to the hot water storage tank 76 is completed,
The operation shifts to a start standby mode in which the operation of the short hair selection / start key 31 or the medium / long hair selection / start key 33 is accepted. At this time, the initial drain standby mode is continued as it is.
Thereafter, when the short hair selection / start key 31 or the medium / long hair selection / start key 33 is pressed, each standby mode shifts to a hair washing processing mode.

A beautician or the like can operate the drain key 49 when the operation mode of the automatic hair washer is the above-mentioned initial drain standby mode. That is, the drainage key 49 can be operated during or after hot water supply is completed. On the other hand, the microcomputer 200 monitors whether or not the drain key 49 has been pressed (step S1). As a result, when it is determined that the drain key 49 has not been pressed, a drain key flag described later is set to “0” (step S2). On the other hand, if it is determined that the drain key 49 has been pressed, first, the drain key flag is set to "1" (step S3), and then the drain key 49 is continuously operated for a predetermined time t (for example, t = 2 seconds). Then, it is determined whether or not the button is pressed (step S4).
As a result, when it is determined that the continuous pressing time is less than the fixed time t, the manual initial drainage process is performed over a predetermined initial drainage time (steps S5 and S6).

More specifically, in the manual initial drainage stroke,
Pump 91, upper nozzle valve 101, lower nozzle valve 1
02, fixed nozzle valve 103 and drain valve 104
Is turned on (step S5). When the pump 91 is turned on, the suction operation of the hot water stored in the hot water storage tank 76 is performed. At this time, prior to the hot water stored in the hot water storage tank 76, the cold water stored in the outflow pipe 89 or the like is supplied to the upper nozzle link 61, the lower nozzle link 63, and the fixed nozzle 66. As a result, the cold water is supplied to the upper nozzle 6
2. It is jetted from the lower nozzle 64 and the fixed nozzle 66. The cold water is supplied to the drain trap 109 and the drain pipe 110.
The water is also drained outside the machine via the drain pipe 87. The injection of the hot water stored in the hot water storage tank 76 is performed after the cold water stored in the outflow pipe 89 or the like is completely drained.

In the manual initial drainage stroke, the pump 91 is driven by the inverter 90 to rotate at a low speed. Therefore,
The warm water suction operation is performed slowly. Therefore, when the cold water is injected from the upper nozzle link 61 or the like, the cold water is injected with a chorochoro. Therefore, even if the hood 3 is not closed, the injected cold water does not leak out of the machine.
Therefore, a beautician or the like can check the temperature of the jetted water by hand or the like.

An opening / closing member including a hood switch that is turned on when the hood 3 is closed and an entrance switch that is turned on when the entrance 2 is closed is provided, and the entrance 2 is closed by the opening / closing member and the entrance switch is turned on. The pump 91 is provided on condition that the hood switch is turned on.
May be driven at high speed.

In this configuration, cold water is squirted only when the inlet 2 and the hood 3 are closed. Therefore, the manual initial drainage stroke can be completed in a shorter time than when the pump 91 is driven to rotate at a low speed.

In the microcomputer 200, during the execution of the manual initial drainage process, an initial drainage time t ₁ (for example, t ₁ = from the start of the manual initial drainage process)
It is monitored whether 20 seconds have elapsed (step S).
6). As a result, when it is determined that the initial drainage time t ₁ elapsed from the start of the manual initial drainage process, the pump 91, the upper nozzle valve 101, the lower nozzle valve 102, stationary nozzle valve 103 and drain valve 104 is turned off, the manual initial The drain stroke ends (step S9).

On the other hand, as a result of the determination in the above step S1,
If it is determined that the drain key 49 has been pressed for a certain period of time t or more, the pump 9 is pressed in the same manner as in step S2.
1. The upper nozzle valve 101, the lower nozzle valve 102, the fixed nozzle valve 103, and the drain valve 104 are turned on, and a manual initial drain stroke is executed (step S7).

However, when the drain key 49 has been pressed for a certain period of time t or more, the microcomputer 200 does not monitor whether the initial drainage time t _{1 has} elapsed since the start of the manual initial drainage process, but instead drains water. It is monitored whether the key 49 is turned off (step S8). As a result, when it is determined that the drain key 49 has been turned off, the pump 91, the upper nozzle valve 101, the lower nozzle valve 10
2. The fixed nozzle valve 103 and the drain valve 104 are turned off, and the manual initial drain process ends (step S).
9).

As described above, in this automatic hair washer, a manual initial drainage step for draining cold water can be executed by pressing the drain key 49 before the hair washing step is executed. Therefore, it is possible to confirm whether or not the cold water has been completely drained before the hair-washing person can be washed. That is, since the hot water stored in the hot water storage tank 76 is jetted from the upper nozzle 62 or the like after the cold water is completely drained, if the temperature of the jetted water is checked by hand or the like, the cold water is completely drained. You can check if it was done.

Therefore, after confirming whether or not the cold water has been completely drained, the hair washing process described later can be executed. Therefore, the automatic hair washing machine is installed in a place where it is easily exposed to the outside air and used. , Or when used in winter, the initial drainage can be sufficiently performed. Therefore, cold water does not hit the hair-washing person. Therefore, the person to be washed can receive the washing with comfortable warm water from the start of the washing.

Moreover, in this automatic hair washer, the execution time of the manual initial drainage process can be adjusted by the continuous pressing time of the draining key 49, so that if the initial drainage time t
Even if the cold water is not completely drained in _one manual initial drainage process, the cold water can be completely drained by pressing the draining key 49 continuously until the injected water reaches an appropriate temperature.

FIG. 6 is a flowchart for explaining the overall flow of the hair washing process executed when the full course is selected as the hair washing course in this automatic hair washing machine. In the start standby mode, when the short hair selection / start key 31 or the medium / long hair selection / start key 33 is pressed (step P1), first, water is determined to determine whether or not the manual initial drainage processing has been executed. It is determined whether the key-off flag is "0" or "1" (step P2). As a result, if the drain key flag is “0”, it is determined that the manual initial drainage process has not been performed, and the initial drainage process for draining the cold water is performed as usual (step P3).

In the initial drainage process, the pump 91, the upper nozzle valve 101, the lower nozzle valve 102, the fixed nozzle valve 103, and the drain valve 104 are turned on as in the manual initial drainage process. As a result, the cold water accumulated in the outflow pipe 89 and the like is drained. When the initial drainage process is completed, the process proceeds to the pre-washing process (Step P4).

On the other hand, if the drain key flag is "1", it is determined that the manual initial drainage process has been executed, and the process directly shifts to the pre-washing process without executing the initial draining process (step P4). This is because the cold water has already been drained in the manual initial drainage treatment.

As described above, when the manual initial drainage process is being performed, the initial drainage process (about 26 seconds) is not performed, so that the hair washing time can be reduced.

It is not always necessary to stop the execution of the initial drainage process. In the pre-washing process, the upper nozzle valve 101 and the lower nozzle valve 102 are turned on, and the pump 91 is driven by the inverter 90 with a relatively strong driving force. As a result, hot water is jetted from the upper nozzle 62 and the lower nozzle 64 with a relatively strong jetting force. When the pre-washing process is completed, the process shifts to a shampoo process (step P5).

In the shampoo process, the shampoo valve 9
8. The shampoo pump 94, the upper nozzle valve 101, the lower nozzle valve 102, and the pump 91 are turned on. As a result, hot water for shampoo is produced in the outflow pipe 89, and the hot water for shampoo is jetted from the upper nozzle 62 and the lower nozzle 64. Thereby, shampoo is performed. When the shampooing process is completed, the process shifts to a rinsing process (step P6).

In the rinsing stroke, the upper nozzle valve 101,
The lower nozzle valve 102 and the pump 91 are turned on.
As a result, warm water in which a chemical solution such as a shampoo solution is not mixed is jetted from the upper nozzle 62 and the lower nozzle 64 as it is. Thereby, the shampoo and the like adhering to the hair of the person to be washed are washed away.

When the rinsing step is completed, the same shampooing step and rinsing step are repeated (steps P7 and P8).

Thereafter, a treatment step is performed (step P9). In the treatment process, the treatment valve 99, the treatment pump 96, the upper nozzle valve 101, the lower nozzle valve 102, and the pump 9
1 is turned on. As a result, hot water for treatment is produced in the outflow pipe 89, and the hot water for treatment is jetted from the upper nozzle 62 and the lower nozzle 64. Thereby, the treatment is performed.

Then, a final rinsing step for finally rinsing the shampoo solution and the treatment solution adhered to the hair of the person to be washed is performed (step P10). In this final rinsing stroke, the upper nozzle valve 101, the lower nozzle valve 102, and the pump 91 are turned on, as in the above rinsing stroke.
