TECHNICAL FIELD OF THE INVENTION
The present invention relates to an automatic hair washer that stores hot water in a hot water storage tank, draws out the hot water, and uses the hot water for hair washing.
[0002]
[Prior art]
2. Description of the Related Art An automatic hair washer that stores hot water in a hot water storage tank and uses it for hair washing is known. In this type of automatic hair washer, the temperature of hot water stored in a hot water storage tank must be adjusted to a temperature suitable for hair washing. The supply of hot water to the hot water storage tank is generally performed by a mixing valve. Water or hot water is supplied to the mixing valve from an external water supply facility or hot water supply facility provided at the installation location of the automatic hair washer. The mixing valve mixes the water or hot water at a predetermined ratio to produce hot water, and supplies the hot water to the hot water storage tank.
[0003]
However, the ability to supply water or hot water from the water supply equipment or hot water supply equipment to the automatic hair washer varies depending on the operating environment, season, time, and the like.
As an example, there are many faucets in a beauty salon or the like, and water or hot water flows out from the many faucets. When all the faucets are closed, the pressure of the water supplied from the water supply equipment or hot water supply equipment to the automatic hair washer is high, and the pressure of the hot water is also high. However, when some faucets are opened, the pressure of water and hot water supplied to the automatic hair washer, the supply amount per unit time, and the like differ.
[0004]
[Problems to be solved by the invention]
As described above, the amount and temperature of the hot water supplied to the hot water storage tank of the automatic hair washer is affected by the operating environment of a beauty salon or the like in which the automatic hair washer is installed.
Therefore, it may be affected by the operating environment (such as the capacity of water supply facilities, the capacity of hot water supply facilities (boiler capacity), whether or not the water supply faucet, the hot water supply faucet, etc.) of the beauty salon etc. where the automatic hair washer is installed. It is preferable that hot water suitable for automatic hair washing is always supplied to the hot water storage tank without being affected by the season or time of use.
[0005]
In addition, during automatic hair washing, when the single-use operation mode that uses up the hot water stored in the hot water storage tank is selected, even if there is a variation in the hot water supply capacity of the hot water supply means, the hot water in the hot water storage tank can be completely used up at the end of operation. Operation control is desired.
Furthermore, in the initial stage of the automatic hair-washing operation, there is a case where an initial drainage is performed in which the cold water remaining in the water channel from the hot water storage tank to the valve is drained. The initial drainage is preferably performed in a short time as possible. However, when the cold water that is initially drained hits the head of the person to be washed, the person to be washed feels uncomfortable, so that the initial drainage must be prevented from vigorously jumping out of the nozzle.
[0006]

The hot water produced by the mixing valve 41 is guided to the hand shower 4 via the supply hose 49 when the hand shower cock 8 is opened. As a result, hot water can be jetted from the hand shower 4.
[0032]
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. 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 drawn out through the outflow pipe 57 and is sucked into the pump 59.

[0038]
FIG. 6 is a block diagram illustrating a configuration of a control circuit of the automatic hair washer 1. FIG. 6 shows only control elements that are features of this embodiment.
The control of the automatic hair washer 1 is performed by the microcomputer 17. On the control plate 7 described above, a temperature key 19 (for setting the temperature of the hot water mixed by the mixing valve 41), a temperature display 20 (for displaying the temperature of the hot water set with the temperature key 19), an operation key 21 (Instructs start / end of automatic hair washing operation), hot water supply key 22 (operates when hot water is stored in hot water storage tank 45) operation selection key 23 (operates to select operation details and hair washing course), initial drainage key 25, a pressure up / down key 34 and the like. The signals of these keys are given to the microcomputer 17, which controls the display of the temperature display 20.
[0039]
The temperature of the hot water detected by the thermistor 46 provided in the supply pipe 44 and the thermistor 52 provided in the hot water storage tank 45 is supplied to the microcomputer 17. Further, the detection outputs of the upper H water amount sensor 51, the middle M water amount sensor 48, and the lower L water amount sensor 50 are also provided to the microcomputer 17.
The microcomputer 17 controls the hot water supply valve 43, the drain valve 82, the circulation valve 83, the inverter 58, and the pump 59 based on each input signal.
[0040]
7 and 8 are flowcharts showing a method of controlling hot water supply to hot water storage tank 45. The hot water supply control will be described with reference to FIGS.
When the operation key 21 is pressed or the hot water supply key 22 is pressed, the microcomputer 17 executes hot water supply control. In the hot water supply control, the hot water supply valve 43 is opened (turned on), and the supply of hot water from the mixing valve 41 to the hot water storage tank 45 via the supply pipe 44 is started (step S1). At this time, the microcomputer 17 determines whether or not the hot water storage tank 45 is hot water supply from an empty state based on the output of the lower L water amount sensor 50 provided in the hot water storage tank 45 (step S2). In the case of hot water supply from the sky, if it is determined that the water level in hot water storage tank 45 has reached water level M (the water level detected by middle M water quantity sensor 48) (YES in step S3), the stored hot water It is determined whether the temperature is 30 ° C. or lower (step S4). This determination is made based on the output of the thermistor 52 provided in the hot water storage tank 45.
[0041]
If the temperature of the hot water stored in the hot water storage tank 45 up to the water level M is 30 ° C. or lower, the pump 59 is operated and the drain valve 82 is opened while continuing to supply hot water to the hot water storage tank 45, and the hot water storage tank 45 is opened. The warm water inside is drained, for example, for 20 seconds (step S5).
Thus, when the temperature of the hot water stored in the hot water storage tank 45 (approximately half) is lower than the temperature suitable for the hair washing, the hot water having the temperature suitable for the hair washing is continuously supplied while draining the water. become.
[0042]
The cause of the decrease in the temperature of the hot water initially stored in the hot water storage tank 45 is, for example, when starting hot water supply in the morning, the temperature of the water until it reaches the mixing valve 41 is low, and the temperature of the hot water is low. It is conceivable that the temperature of the hot water output from the mixing valve 41 is low because of insufficient heating. Since the temperature of the hot water supplied to the mixing valve 41 rises over time, the hot water output from the mixing valve 41 eventually becomes stable at the set temperature.
[0043]
However, since it may take time for the temperature of the hot water output from the mixing valve 41 to reach the set temperature, the control of steps S6 to S9 is performed in consideration of such a situation.
That is, a temperature difference (AB) between the set temperature A of the mixing valve 41 and the temperature B of the hot water output from the mixing valve 41 is detected, and it is determined whether or not (AB)> 10 ° C. Is performed (step S6). The hot water temperature output from the mixing valve 41 is detected by a thermistor 46. The set temperature B of the mixing valve 41 is set by the temperature key 19.
[0044]
In the microcomputer 17, when (A−B)> 10 ° C., the set temperature of the mixing valve 41 is increased by + 1 ° C. (step S7), and the temperature difference (A−B) between the set temperature B and the output temperature B is: When (AB) <2 ° C., the set temperature of the mixing valve 41 is returned to the original temperature (steps S8 and S9).
With this control, the time required for the temperature of the hot water output from the mixing valve 41 to rise to the set temperature can be shortened, and hot water of an appropriate temperature suitable for washing hair can be quickly stored in the hot water storage tank 45.
[0045]
When the water level of the hot water stored in hot water storage tank 45 reaches water level H detected by upper H water amount sensor 51 (YES in step S10), the set temperature of mixing valve 41 is returned to the original temperature (step S11). .
Next, in step S12, it is determined whether or not the water level of the hot water storage tank 45 has become H (the water level detected by the upper H water amount sensor 51). Hot water supply valve 43 is closed. Then, the device enters a standby state (step S13).
[0046]
In the standby state, the control for keeping warm water in the hot water storage tank 45 and circulating the hot water described below is performed until the hair washing operation, the draining operation, or the initial draining operation is started.
That is, the hot water stored in the hot water storage tank 45 is pumped out by the pump 59 and returned to the hot water storage tank 45 via the circulation water channel 63, for example, every 15 minutes after the standby state. By this circulation processing, the hot water in the hot water storage tank 45 is favorably stirred, and a temperature difference in the hot water storage tank 45 (for example, a situation in which the lower temperature is low and the upper temperature is high) can be prevented.
[0047]
Specifically, the circulation valve 83 is opened every 15 minutes from the standby state, and the pump 59 is driven at a frequency of 30 Hz. In this case, the other valves, that is, the upper and lower nozzle valves 76 and 77, the fixed nozzle valves 78 to 81, and the drain valve 82 are closed. (Step S15). When the pump 59 is operated for two minutes, the circulation valve 83 is closed and the pump 59 is stopped (steps S16 and S17).
[0048]
In this way, the pump 59 is intermittently operated to circulate the hot water in the hot water storage tank 45, thereby preventing the hot water in the hot water storage tank 45 from being mixed and preventing a temperature difference from occurring.
A heater 64 may be provided in the circulation water channel 63. The configuration may be such that the warm water circulating in the circulation channel 63 is heated by the heater 64. By doing so, the hot water is heated during circulation and the heated hot water is returned to the hot water storage tank 45, so that the temperature of the hot water stored in the hot water storage tank 45 can be prevented from lowering.
[0049]
When the hot water storage tank 45 is provided with a heater for keeping heat (not shown), the heater 64 as described above need not be provided in the circulation water passage 63. In this case, the heater for keeping heat provided in the hot water storage tank 45 may be controlled in the procedure of steps S18 to S26 described below.
That is, the heating heater of the hot water storage tank 45 is turned on (step S18), and it is waited that 10 seconds have elapsed since the hot water temperature detected by the thermistor 52 reaches a predetermined set temperature due to the turning on of the heating heater. (Step S19) When 10 seconds have elapsed after the arrival, the heater for keeping heat is turned off (Step S20). Then, such ON / OFF control of the heater is performed, for example, at an interval of 15 minutes (steps S21, S22, S23, S24). The on / off control of the warming heater can prevent the hot water in the hot water storage tank 45 from cooling.
[0050]
Note that the hot water circulation control in steps S15 to S17 may be performed in parallel with the on / off control of the heater.
When the start of washing, the start of drainage, or the start of initial drainage are instructed (YES in step S25), the on / off control (heater control control) of the heater is interrupted (step S26).
The hot water is stored in the hot water storage tank 45 as described above. In the case where the stored hot water is pumped out and the hair is washed, control of the operation of using up the hot water will be described below.
[0051]
Normally, the hot water storage tank 45 is provided with a heater for keeping heat as described above, and in a state where the hot water is stored in the hot water storage tank 45, the hot water is not cooled. The amount of warm water filled in the hot water storage tank 45 is, for example, about 35 liters, and this amount may be sufficient to complete the automatic hair washing, or may be insufficient. This is because in automatic hair washing, for example, a short hair course for washing short hair, a long hair course for washing long hair, and the like can be selected, and the necessity of treatment can be switched depending on the course. Therefore, it is necessary to supply hot water to the hot water storage tank 45 as necessary.
[0052]
By the way, some beauty salons desire to use up the hot water in the hot water storage tank 45 when the automatic hair washing is completed. The following control is a control developed to meet such a demand.
Referring to FIG. 9, when the hair-washing operation is started, the microcomputer 17 determines whether or not the operation is a one-time use operation (step P1). Whether or not the single-use operation is performed is set by an operation selection key 23 provided on the control plate 7. When the operation is not the single use operation, the microcomputer 17 performs the normal operation control (Step P21).
[0053]
In the single use operation control, the supply hot water time is calculated by the microcomputer 17 (step P2). The amount of hot water to be supplied to the hot water storage tank 45 varies depending on the selected operation content (for example, a short hair course, a long hair course, a full course, a treatment course, and the like). Is calculated based on
By the calculation of the hot water supply time, the hot water storage tank 45 is supplied with an amount of hot water necessary for the hair washing operation. Therefore, when the hair washing operation is completed, the hot water in the hot water storage tank 45 is used up.
[0054]
However, since the hot water supply capacity, water pressure, and the like of the beauty salon change depending on the operating environment and the time zone as described above, even if hot water is replenished for the same time, the replenishment amount changes. Therefore, even if the supply amount changes, the change is absorbed by the following processing.
The microcomputer 17 turns off the control of the hot water supply valve 43 after the supply hot water time has elapsed (steps P3 and P4). Then, it is determined whether or not one minute before the end of the hair washing operation (step P5).
[0055]
One minute before the end, the counting of the shampooing process time is stopped (step P6), and it is determined whether or not the hot water storage tank 45 is below the water level M (step P7). This determination is made based on the output of the middle water quantity sensor 48.
In other words, in the single-use operation control, the standard is that the amount of warm water remaining in the hot water storage tank 45 is the water level M one minute before the end of the hair washing operation.
If the remaining water amount is less than the water level M, the microcomputer 17 switches the spraying pressure to a low level in the subsequent hair washing process in a short hair course using a small amount of water, and causes the operation to be performed for 20 seconds (step P8). , P9). Next, the stroke time counting is restarted, and the hot water blown out from the nozzle sets the pressure of the short hair course to low. Further, when the full course or the treatment course is selected, the treatment pump 66 is turned on to perform the treatment, and the operation is performed for 25 seconds in that state (steps P10 and P11). Then, the treatment pump 66 is turned off (step P12), and the rinsing operation is further performed for 15 seconds.
[0056]
Thereafter, the drain valve 82 is turned on, the pump 59 is driven at a frequency of 10 Hz, and when the hot water storage tank 45 reaches the water level L, the remaining time display is set to "0" (steps P18, P19), and the operation is terminated.
In step P7, if the hot water storage tank 45 is not below the water level M, that is, if hot water exceeding the water level M remains in the hot water storage tank 45 one minute before the end of the hair-washing operation, immediately before the water level M is reached, Is extended (steps P14, P15). When the water level reaches M, the stroke time counting is restarted (step P16), and the remaining strokes are executed (step P17). When the remaining stroke is completed, the water level in the hot water storage tank 45 is determined. If the water level is not L, the drain valve 82 is turned on, and the pump 59 is driven at a frequency of 10 Hz.

When the water level of the hot water storage tank 45 reaches the water level L, the remaining time display is set to "0" (step P19), and the operation is terminated.
With the above-described control, in the single-use operation, even if the amount of the remaining hot water in the hot water storage tank 45 is less than the water level M one minute before the end of the hair washing operation, the hair washing operation is satisfactorily terminated without further supplying hot water. be able to.
If the water level is less than the water level M in step P7 described above, hot water may be supplied to the hot water storage tank 45 instead of performing the processing in steps P8 to P13. The replenishing hot water may be performed until the water level reaches M, and thereafter, the processing after step P16 may be performed.
[0058]
Next, the adjustment control of the initial drainage will be described.
FIG. 10 is a flowchart showing the adjustment control operation of the initial drainage.
When the initial drain key 25 provided on the control plate 7 is depressed once, the counter is depressed one and continuously (continuity means, for example, not to wait for one second or more) twice. When the counter is pressed two or three times, 3 is stored in the counter (steps Q1 to Q6).
[0059]
Then, the drain valve 82 is opened (in this case, all other valves are closed), and the pump 59 is driven at a frequency of 48 Hz for 6 seconds (steps Q7 and Q8).
Next, the fixed nozzle valves 78, 79, 80, 81 are opened (the other valves are closed, and the drain valve 82 opened in step Q7 is also closed), and the pump 59 is driven at a frequency of 5 Hz. This is continued for 8 seconds (steps Q9 and Q11). During this eight seconds, the frequency can be adjusted by the pressure up / down key 34 provided on the control plate 7. During the frequency adjustment, the time count of 8 seconds is stopped.
[0060]
By this pressure adjustment, the drive frequency of the pump 59 is increased or decreased. The operator confirms the momentum of the water coming out of the fixed nozzles 14, 28, 29, 30 so that the water coming out of each of the fixed nozzles 14, 28, 29, 30 blows out at such a degree that the water does not fall on the hair of the person to be washed. The drive frequency of the pump 59 is adjusted by the pressure up / down key 34. This drive frequency is stored in the microcomputer 17.
Next, the lower nozzle valve 77 is opened (the other valves are closed), and the pump 59 is driven at a frequency of 5 Hz, which is continued for 11 seconds (steps Q12 and Q14). During that time, the drive frequency of the pump 59 can be adjusted by the pressure up / down key 34 (step Q13). During this adjustment, the time count of 11 seconds is stopped.
[0061]
Therefore, during the steps Q12 to Q14, the operator confirms the momentum of the water spouted from the lower nozzle link 13 while preventing the water spouting from the lower nozzle link 13 during the initial drainage from impinging on the neck of the hair-washing person. Momentum can be set.
Thereafter, the upper nozzle valve 76 is opened (at this time, the other valves are closed).
[0062]
Then, the pump 59 is driven at a frequency of 5 Hz, which lasts for 11 seconds (steps Q15 and Q17). Also at this time, the operator can adjust the drive frequency of the pump 59 by using the pressure up / down key 34 (step Q16). By this adjustment, the momentum of the water spouted from the upper nozzle link 12 is adjusted so as not to be applied to the hair of the person to be washed and not to be too weak.
Thereafter, the count value of the counter is decremented by 1 (step Q18), the processing from step Q9 is continued until the count value becomes 0, and the initial drainage adjustment processing ends.
[0063]
The drive frequency of the pump 59 set as described above, that is, the frequency of the pump 59 set in steps Q9, Q12, and Q16 is stored in the microcomputer 17, and the corresponding valve is opened at the time of initial drainage thereafter. When set, the pump 59 is driven at the set frequency.
By such a process, for each type of nozzle provided in the water tank 11, initial drainage is performed to discharge cold water, and the momentum of the drainage can be individually set according to the type of nozzle. In other words, even if the pump 59 is driven at the same drive frequency depending on the type of nozzle, the power of the water spouting from the nozzle is different, so the optimum pump drive frequency is set for each type of nozzle. Thereby, it is possible to discharge cold water from each nozzle in a short time, and it is possible to obtain an effect that the cold water does not splash on the head of the person to be washed.
