[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic shampoo machine in which hair is washed by shampoo and automatic discharge of washing water.

[0002]

2. Description of the Related Art An automatic hair washer has been conventionally used in which a shampoo and a washing water are applied to a hair at a set timing so that the hair can be automatically washed from wet to final rinsing. The basics of this automatic hair washer are to have a ball large enough to accept the head when the person is lying on his back, and to automatically send washing water and shampoo liquid to the ball. .

[0003] For example, Japanese Patent Publication No. 56-18207 discloses an automatic hair-washing device in which a ball swinging head capable of changing its posture with respect to the head is provided in a ball, and the head swinging wheel is provided with a plurality of nozzles. Machine is listed.

[0004] This apparatus is provided with a flow path system for supplying only washing water at an appropriate temperature or a mixture of shampoo liquid with the washing water to discharge washing water, shampoo liquid and the like from a nozzle. The flow path system incorporates a valve for switching or opening and closing the flow path in the order of hot water discharge during initial wet supply, shampoo supply for hair washing, and subsequent rinsing.

In such a hair washer, the hair can be automatically washed without feeling cold or hot as long as the supplied hot water or the temperature of the water is kept appropriate.

[0006]

The hot water to be supplied at the time of wet or rinsing can be, for example, an electric water heater built in an automatic hair washer or a thermostat mixing valve having an automatic temperature adjusting function incorporated in the flow path. Therefore, it is possible to maintain a comfortable temperature.

[0007] However, if it is left for a single use, the hot water remaining in the hot water supply source and the flow path to the nozzle cools. For this reason, when used again, the cold water remaining in this flow path will be pushed out and discharged from the nozzle, giving the user discomfort especially in the cold winter season. I will.

Further, even when a shampoo or a rinsing liquid or the like is used in addition to the shampoo or the rinsing liquid, the rinsing liquid remains in the flow path if it is used once. For this reason, even when only rinsing is required when used later, these shampoos and rinsing solutions are bathed, and there is an obstacle to usability.

As described above, in the conventional automatic hair washer, the washing water, the shampoo solution, and the like remain in the flow path after being used once, so that the comfort is easily lost when the hair is used later.

The problem to be solved in the present invention is to prevent the discharge of a low-temperature washing water or a washing liquid containing a shampoo solution in the initial stage of use so that it can always be used comfortably.

[0011]

According to the present invention, there are provided a plurality of discharge portions for injecting cleaning water such as hot water or water and a liquid material such as shampoo toward the inside of a ball; a flow path system for supplying a plurality of opening and closing valves and, for came draining provided in the flow channel opening and closing valve for opening and closing the flow path to the discharge unit incorporated in the flow path system,捨湯channel and捨湯off valve provided in said opening and closing valve, an automatic hair washing machine and a control means for controlling operation of the on-off valve can drainage and the捨湯off valve, start cleaning by said control means based on the signal, the on-off valve, collecting waste the on-off valve can drainage and the捨湯off valve and opening and closing of the flow path to the discharge portion remaining water, the residual liquid out of the channel system The system is characterized by comprising

Further, a throttle may be provided in the flow path on the upstream side of the on-off valve to reduce the supply pressure from the upstream side.

[0013]

[Function] After using the hair washer, these hot water, water and shampoo liquid remain in the hot water and water supply path and the shampoo supply path, and these residual water and residual liquid remain until the next use. It gets cold. On the other hand, before supplying hot water, water, shampoo, or the like to the discharge unit according to a washing start signal at the time of next use, for example, opening and closing an on-off valve incorporated in a flow path to the discharge unit, and then supplying hot water. This makes it possible to drain residual water and liquid remaining from the discharge section.

As described above, at the time of starting the use, the residual water and the residual liquid when used earlier are taken out from the flow path system to the discharge portion, so that the liquid containing the cold washing water and the shampoo is bathed. Disappears. In addition, even in the case of rinsing, it is possible to quickly wash hair without bathing the liquid containing the remaining shampoo.

The nozzle head 4 is provided with a mixed water supply path 6.
The supply and stop of the mixed water are performed by an on-off valve 9 located at the end of c and downstream of the branch flow path to each nozzle head 3. A supply system for the shampoo liquid from the tank 8 is connected to these nozzle heads 4 as a separate system from the supply system for the mixed water. A pump 8a is incorporated in the supply path from the tank 8, and by operating this pump 8a, a fixed amount of shampoo liquid is simultaneously supplied to each nozzle head 4, and diluted with the mixed water so that water can be sprinkled.

Here, the manual type hand shower 1f is arranged at the most upstream side, and the main opening / closing valve 10 is incorporated between the hand shower 1f and three rows of the downstream shower heads. While the main on-off valve 10 is closed, the mixed water from the hot and cold water mixing tap 6 can be supplied only to the hand shower 1f, and the discharge and stop of the mixed water are performed by operating the manual flow rate control valve 1i. Will be Further, a bypass flow path 10a is provided between the primary side and the secondary side of the main opening / closing valve 10, and a throttle 10b that allows only a low flow rate is incorporated in the bypass flow path 10a. When draining water, the main opening / closing valve 10 is closed, and when hot water is supplied from the hot water mixer tap 6 to the downstream shower heads 3 and 5 and the nozzle head 4, the supply pressure is reduced by passing through the throttle 10 b, Prevent the jet of water from being jetted from the nozzles 3 and 5 or the nozzle head 4 vigorously.

Further, at the downstream end of the row of shower heads 3e to 3i, a drainage opening / closing valve 11 for collecting hot water or water that has not been drained to the ball 1 side is provided. The drainage on-off valve 11 stops the supply after being supplied from the hot and cold water mixing tap 6, and at this time, the mixed water still remaining in the shower heads 3, 5 and the nozzle head 4 is removed by the ball 1. It has a function to discharge and collect to the side. On the other hand, a hot water flow path 6d is branched from the hot water side of the hot / water mixer tap 6 and upstream of the check valve 6b, and a hot water opening / closing valve 12 is provided in the hot water flow path 6d.

Here, each of the on-off valves 1g, 3a to 3i, 5a, 9 provided in the flow path system from the hot and cold water mixing tap 6, the main on-off valve 1
0, the drainage on-off valve 11 and the hot water on-off valve 12 are all of an electromagnetic valve type, and each can be opened and closed by a signal from the controller 20. The main on-off valve 10, the drainage on-off valve 11, and the hot water on-off valve 12 are all controlled to open and close according to the temperature of the hot water reaching them. For this control, the hot water mixer tap 6 and the hot water on-off valve 1

The temperature sensor 13 provided in the hot water flow path 6d is
The temperature of the hot water supplied from the hot water supply source is detected, and if the hot water temperature is in a temperature range of, for example, about 47 ± 3 ° C., the open / close valve 12 is opened and closed so that the hot water supply tap 6 can be supplied. Is controlled by the controller 20. That is,
If the temperature is lower or higher than this temperature range, the hot water opening / closing valve 12 is opened so that hot water is discarded to the ball 1 side, so that abnormally high and abnormally low temperature hot water is not supplied to the flow path system. Then, when the temperature is within the above-mentioned temperature range, the hot water on-off valve 12 is closed, and hot water from the hot water supply source is supplied from the hot / water mixer tap 6 to the downstream side.

The temperature sensor 14 disposed upstream of the main on-off valve 10 opens the main on-off valve 10 by a signal to the controller 20 when the temperature of the supplied mixed water reaches 40 ° C. To control. By such opening control of the main opening / closing valve 10, the washing water from each discharge end of the shower head 3 or the like can be maintained in a certain comfortable temperature range.

Further, a temperature sensor 15 disposed on the downstream side
Is incorporated in order for the controller 20 to open the drainage on-off valve 11 when the temperature of the mixed water passing through reaches 30 ° C. And the temperature sensor 1 on the upstream side
4 detects 40 ° C., this drainage on-off valve 1
1 is controlled by the controller 20 so as to perform a valve closing operation.

Here, the timing of the supply of hot water or water from the hot and cold mixing tap 6, the supply of shampoo from the tank 8, and the supply of compressed air from the compressor 7 are determined by the operation panel 1.
The controller 2 receives a signal from the switch operation of d.
Each device may be controlled by 0. Then, when the automatic switch of the operation panel 1d is turned on for automatic cleaning, wetting by the initial cleaning water from the shower heads 3,5, water discharge of the shampoo from the nozzle head 4 and water discharge from the shower heads 3,5, The controller 20 controls the cleaning process so that the washing process proceeds in the order of water discharge from all the shower heads 3 and 5 for rinsing.

In the above configuration, at the time of initial cleaning, hot water is released from the shower heads 3 and 5 to wet the hair, and then the shampoo liquid is released from the nozzle head 4 and shampooed. Next, when the shampooing process is completed, rinsing is performed by discharging hot water or water from each shower head 3,5.

Here, after the hot water or water remaining in the flow path system after one use is cooled, the hot water or the water is prevented from being discharged, and the extremely high or low mixed water is prevented from being supplied from the hot / water mixing tap 6. Hot water and water are drained by the operation of the main on-off valve 10, the drainage on-off valve 11 and the hot water on-off valve 12.

FIG. 7 is a time chart showing the operation of each on-off valve, which will be described below.

When the automatic shampoo switch of the operation panel 1d is turned on, if the temperature sensor 13 of the hot water flow path 6d is 47 ±
When a temperature outside 3 ° C. is detected, the hot water on / off valve 12 is opened, and the hot water from the hot water supply source is discharged to the ball 1 as it is. Then, when a value in the previous temperature range is detected by the temperature setting, the hot water on-off valve 12 is closed, and at the same time, the on-off valves 5a of the shower head 5 and the on-off valves 3a, 3b of the four shower heads 3 on the upstream side. , 3c and 3d are opened, and the drainage on-off valve 11 is also opened.

On the other hand, by turning on the automatic hair washing switch,
Hot water of an appropriate temperature is also supplied from the hot-water mixer tap 6, and this hot water proceeds downstream through the throttle 10b. For this reason, since the open / close valves 3a to 3d are open, the cold water remaining in the flow path is discharged from each shower head 3 to the ball 1 so as to be pushed out by hot water supply. At this time, since the hot water is depressurized by the throttle 10b, the water does not blow out vigorously from the shower head 3 and the head does not get wet.

After a certain time, the downstream 5
Opening / closing valves 3e, 3f,
The valves 3g, 3h and 3i are opened, and water is discharged from these shower heads 3 and drained using the pushing by hot water supply. After a certain time, the nozzle head 4
The on-off valve 9 for opening and closing the flow path to the side is opened, and the shampoo liquid and the mixed water remaining in the nozzle head 4 and the flow path are similarly discharged by hot water extrusion. Also,
Since the drainage on-off valve 11 is maintained in the open state from the beginning, the remaining water that cannot be drained from the shower head 3 and the nozzle head 5 is removed from the ball 1 by the drainage on-off valve 11.
Can be collected to the side.

When the temperature sensor 14 detects that the temperature of the mixed water is 40 ° C. after such a draining process, all the open / close valves 3a to 3i, 5
When a and 9 are closed, the drainage on-off valve 11 is also closed, and only the main on-off valve 10 is opened.

By the movement of each valve described above, in the initial process of use, all of the hot water, water, and the mixture with the shampoo remaining in the flow path are removed to the ball 1 side, and thereafter, the mixing set at 40 ° C. Water is supplied from the main on-off valve 10 to each discharge end.

FIG. 8 is a time chart showing another drainage timing.

In this example, the upstream shower head 3,
The opening / closing operation of the opening / closing valves 3a to 3d and 5a of FIG. 5 is the same as that of FIG. Then, the valve opening duration of the drainage on-off valve 11 is lengthened, water is drained in order from the shower head 3 close to the drainage on-off valve 11, and finally the on-off valve 9 is opened to drain water from the nozzle head 4. Do. That is, the on-off valves 3i, 3h, 3g, 3f and 3e are opened in order from the side close to the drainage on-off valve 11, and after the downstream side of the adjacent shower head 3 is drained, the upstream shower head continues. Draining from 3 is sequentially performed. Finally, when the drainage from the nozzle head 4 is completed, the hot and cold water mixing tap 6
The mixed liquid containing hot water, water, and shampoo liquid remaining in the flow path from to the respective discharge ends is drained.

FIG. 9 is a schematic diagram showing another example of the flow path system from the hot and cold water mixing tap 6.

In this example, a drainage passage 16a is provided in the mixed water supply path 6c between the hot water mixer tap 6 and the temperature sensor 14 in place of the drainage opening / closing valve 11 provided at the end of the flow path in FIG. This is different from the first embodiment in that the drainage path 16a is provided with a drainage on-off valve 16. In the illustrated example, the main on-off valve 10, the bypass flow path 10a, and the throttle 10b are not provided, but the provision of these elements is optional as in the above-described example. Other channel configurations are the same as those in FIG. 6, and a time chart is shown in FIG.

As in the system shown in FIG. 6, when the automatic switch of the operation panel 1d is turned on, the temperature sensor 13
Hot water on-off valve 1 so that it corresponds to the temperature range of 47 ± 3 ° C
2 is opened and closed, and when the value in the above temperature range is detected,
The hot water on-off valve 12 is closed. At the same time, the drainage on-off valve 1 of the drainage path 16a branched from the mixed water supply path 6c.
6 is opened and closed after a certain period of time.

Thereafter, the open / close valves 3a to 3i, 5a, 9 are opened, so that the cold water remaining up to each discharge end is pushed out by hot water supplied from the hot and cold water mixing tap 6, and the shower heads 3, 5 and the nozzle The water is discharged from the head 4 and drained. In the case where the main on-off valve 10, the throttle 10b, and the like are provided as in the above-described example, the main on-off valve 1
0 is kept closed to prevent the remaining water and remaining liquid from being discharged to the ball 1 vigorously by reducing the supply pressure of the hot water supply by the throttle 10b of the bypass flow passage 10a.

Next, at the time when the drainage process proceeds and the time is near the completion time, the amount of the mixed water from the hot and cold water mixing tap 6 increases, and when the temperature sensor 14 detects 40 ° C.,
The supply of mixed water at an appropriate temperature is ready. Therefore, when the process proceeds to the automatic cleaning process after the initial drainage process, the mixed water having an appropriate temperature is supplied, and the shower head 3 and the nozzle head 4 do not discharge cold water.

In the embodiment, the shampoo liquid can be discharged in addition to the hot water or the mixed water. However, in addition, the rinsing liquid can be discharged in the same manner, so that the shampoo and the rinsing can be performed. A road configuration can also be used.

[0052]

[Effect of the Invention] In the present invention, after draining hot water and water remaining after prior use and remaining liquid such as shampoo and rinse, a new mixed water or shampoo liquid at an appropriate temperature is directed to the head. Can be bathed. Therefore, each time the hair is used, the hair can be washed with hot water or water at an appropriate temperature, and the hair can be used comfortably without feeling cold. In addition, since the remaining liquid such as shampoo and rinse can be removed first, there is no needless consumption of water during rinsing.

In the case where water is drained from the discharge portion to the ball side, if the supply pressure of hot water supply or the like from the upstream is reduced by a throttle, the drainage portion is not discharged vigorously from the discharge portion. It can be used comfortably without cold water hitting the head.
