2. Description of the Related Art When trying to wash hair using an automatic hair washing machine, it is the first time to use it in the morning, or when a considerable amount of time has passed from the last use to this time in winter In many cases, the initial water sprayed from the nozzle is often cold. Spraying such chilled cold water onto the head of the person to be washed causes an unpleasant feeling on the person to be washed, which is not preferable.

As a conventional technique for preventing the injection of cold water at the start of use in an automatic hair washing machine, Japanese Patent Publication No. 52-11248 and Japanese Patent Publication No. 52-31 are disclosed.
There is one described in Japanese Patent No. 791. In the prior art described in the above publication, a valve is inserted near a jet nozzle of a water channel provided in an automatic hair washing machine, and a bypass pipe is installed from the valve to a hot water storage tank so that cold water accumulated in the water channel is temporarily stored in the hot water storage tank. It is configured to return to.

[0004]

Therefore, the prior art with the above-mentioned structure has a drawback that the valve and the bypass pipe are indispensable and the structure thereof becomes complicated. In addition, since the cold water in the pipe from the inserted valve to the spray nozzle cannot be removed as it is, the cold water remaining in the pipe is splashed on the hair of the person being washed when the automatic hair washing machine is started. In other words, the cold water was not completely removed.

The present invention solves the above-mentioned drawbacks of the prior art, and even when cold water remains in the piping of an automatic hair washing machine, the cold water is applied to the head and hair of the person being washed at the start of use. It is an object of the present invention to provide an automatic hair washing machine improved so as not to be sprayed.

[0006]

In order to achieve the above object, the automatic hair washing machine according to claim 1 is an automatic hair washing machine having washing water jetting means for jetting washing water onto hair. The water jetting means comprises a nozzle for jetting washing water, a pump for applying pressure to the washing water supplied to the nozzle, and an inverter for driving and controlling the pump.
Note that the inverter will wash out the nozzle for a specified period.
To reduce the pump capacity so that the purified water is in a non-injection state
It is characterized by controlling .

According to the above configuration, the inverter is used for a predetermined period , for example, a predetermined time from the start of use .
Pump capacity is limited. If the capacity of the pump is limited, the pressure of the washing water supplied to the jet nozzle will drop. Since the pressure drop weakens the momentum of the washing water jetted from the jet nozzle, the washing water slowly flows out from the jet nozzle, and the washing water is drained without reaching the person to be washed, hair or head.

That is, the power of the pump can be arbitrarily changed by the inverter, and the capacity of the pump can be reduced within a desired period. The automatic hair washing machine according to claim 2 is an automatic hair washing machine for washing hair by spraying washing water on the hair, and a washing water supplying means for supplying the washing water and one end of the washing water supplying means. And a water pipe in which injection nozzles are arranged, and the other end of the water pipe,
Drainage adjusting means that opens the other end of the water pipe when the water pressure of the wash water supplied from the wash water supply means to the water pipe is less than a predetermined water pressure and closes the other end of the water pipe when the water pressure is above the predetermined water pressure. It is characterized by.

According to the above construction, when the water pressure of the wash water supplied from the wash water supply means to the water pipe is less than the predetermined water pressure, the drain adjusting means opens the other end of the water pipe.
For example, the water pressure of the wash water supplied to the water pipe is reduced for a predetermined time from the start of use, and the wash water supplied to the water pipe is drained from the other end. That is, so-called initial drainage is performed from the other end. During the actual washing of hair, the water pressure of the wash water supplied from the wash water supply means to the water pipe is set to a predetermined water pressure, and the other end of the water pipe is closed by the drainage adjusting means. Therefore, the cleaning water supplied to the water pipe is sprayed from the spray nozzle without being drained from the other end.

Therefore, since the water can be drained from the other end of the water pipe at the time of the initial drainage, the initial drainage can be completed in a short time to some extent as compared with the case where the water is slowly drained from the jet nozzle. The automatic hair washing machine according to claim 3, which is an automatic hair washing machine for washing hair by spraying hot water onto the hair, wherein a hot water storage tank for storing hot water at a predetermined temperature and a water jet nozzle are arranged. Supply means for supplying the wash water from the hot water storage tank to one end of the water pipe, and a reducing means connected to the other end of the water pipe for reducing the wash water supplied to the water pipe by the supply means to the hot water storage tank for a predetermined period. And are included.

According to the above structure, the wash water supplied to the water pipe by the reducing means is returned to the hot water storage tank for a predetermined period, for example, a predetermined period from the start of use.
For this reason, the reduced cleaning hot water is reused in the subsequent operation, so that the hot water can be effectively used without wastefully draining the cleaning hot water.

As described above, when only one end of the water pipe 551 of the crown nozzle link 55 is held on the water tank side wall 511 and the other end of the water pipe 551 is a free end, that is, a so-called cantilever support structure is used. Assembling workability is improved. This is because, when both ends of the water pipe 551 are rotatably attached to both sides of the side wall of the water tank, the central axis lines of the both side holding portions must be aligned, and when the attachment hole is formed in the side wall, it must be performed accurately. Further, since the holding members on both sides are required, the number of parts is large and the assembling work also takes time. On the other hand, if the above-mentioned cantilever support is used, only one side holding member is required, and
Since it is not necessary to align the central axes, workability during assembly is improved.

However, depending on the model, the nozzle link 55 for the crown does not necessarily have to have a cantilever support structure, and a nozzle link for the crown with a so-called double-support structure is used as in the embodiment described later. Good. FIG. 5 is a perspective view showing a specific configuration of the neckline nozzle link 58. The neckline nozzle link 58 has a water pipe 581 whose tip is closed and extends substantially linearly, and the root of the water pipe 581 penetrates the water tank side wall 511 and projects outward.

The initial drainage refers to the water that first collects in the outflow pipe 93, the pump 94, the nozzle link 55 for the crown, the nozzle link 58 for the neckline, etc. (This water is different from the hot water in the tank 87 and is usually cooled. Cold water). A more specific control content of the initial drainage is shown in FIG.
Shown in Referring to FIG. 11, when the initial drainage starts, first, both the short valve 95 and the long valve 96 are turned on, and the pump 94 is further turned on (step S30). Then, for example, the inverter 106 is controlled so that the rotation speed of the pump 94 is minimized for 5 seconds (step S31).

For the next 5 seconds, for example, the inverter 106 is controlled so as to gradually increase the rotation speed of the pump 94 (step S32). Then, after that, control is performed so as to increase the rotation speed of the pump 94 to a predetermined rotation speed (step S33). The above processing is performed during the time t1 (step S34).

By this initial drainage control, the cold water initially stored in the nozzle links 55, 58 and the like slowly leaks from the jet nozzles 57, 59, 60a, 60b, 60c. Therefore, cold water is not splashed on the head of the person to be washed. Moreover, since the nozzle link 55 for the crown is stopped at the lower position, the water dripping from the nozzle 57 does not splash on the scalp.

Returning to FIG. 10, next, preliminary washing 1 is performed. In the prewash 1, the motor 71 is turned on. When the motor 71 is turned on, the top nozzle link 55 and the neckline nozzle link 58 start to swing and rotate. Further, the short valve 95 is turned on, the long valve 96 is turned off, and the time t is passed from the nozzles 57 and 59 of the crown nozzle link 55 and the neckline nozzle link 58.
Cleaning water is sprayed during 2 (steps S5 and S6).

Next, preliminary washing 2 is performed. In the preliminary washing 2, the short valve 95 is turned off, the long valve 96 is turned on, and the wash water is sprayed from the long hair washing nozzle 60 for the time t3 (steps S7, S).
8). Further, preliminary washing 3 is performed. In the pre-wash 3, both the short valve 95 and the long valve 96 are turned on, and wash water is sprayed from the three types of nozzles 57, 59, 60 during the time t4 (step S).
9, S10).

Next, main washing 1 is performed. In the main wash 1, the short valve 95 is turned on, the long valve 96 is turned off, and the shampoo valve 101 is turned on (step S11). Therefore, when the warm water in the tank 87 is sent to the nozzles 57 and 59 through the outflow pipe 93 by the pump 94, the shampoo liquid stored in the shampoo storage box 11 is mixed into the warm water. Therefore, the hair is washed with washing water mixed with shampoo solution. This main wash 1
Is performed for time t5 (step S12).

Next, main washing 2 is performed. In main wash 2,
The short valve 95 is turned off, and the long valve 96
Is turned on, and the shampoo valve 101 is turned on (step S13). Therefore, hot water containing shampoo liquid is jetted from the long hair washing nozzle 60, and the long hair portion is washed. This main washing 2 is performed for time t6 (step S14).

In each of the above washings, in the preliminary washing 1, the preliminary washing 2, the main washing 1 and the main washing 2, the short valve 95 and the long valve 96 are selectively turned on, and the head of the person to be washed is washed. And the root of the hair and the long hair are washed separately. By doing so, the number of nozzles at which the cleaning water is sprayed at the same time can be reduced to a predetermined number or less, so that the water pressure of the cleaning water can be kept higher than the predetermined pressure, and the force of the cleaning water sprayed from the nozzles can be increased. Has the advantage that it can be kept strong enough for cleaning.

In this way, if the short valve 95 and the long valve 96 are controlled so as to be selectively turned on,
This automatic hair washing machine can be constructed using the pump 94 having a relatively low power, and the entire apparatus can be constructed at low cost and the construction can be downsized.
Of course, if the power of the pump 94 is sufficiently large, the short-circuit valve 95 and the long-valve 96 are turned on at the same time as in the pre-wash 3 so that the washing water is sprayed from all three types of nozzles at the same time. You can also do it.

Next, rinsing 1 is performed. In rinse 1, only the short valve 95 is turned on and the long valve 9 is turned on.
6 and shampoo valve 101 are turned off at time t7.
Hot water for rinsing is sprayed from the nozzle 57 of the nozzle link 55 for the crown of the head and the nozzle 59 of the nozzle link 58 for the neckline (steps S15 and S16). Next, rinsing 2 is performed. In rinse 2, the short valve 95 is turned off, the long valve 96 is turned on, and the shampoo valve 101 is turned off (step S17). Then, during a time t8, hot water for rinsing is sprayed from the long hair cleaning nozzle 60 (step S18).

After that, a treatment is performed. In the treatment, the pressure of the hot water ejected from the three types of nozzles 57, 59, 60 does not need to be so strong, so both the short valve 95 and the long valve 96 are turned on. Further, the treatment valve 104 is turned on (step S19). As a result, the treatment liquid stored in the treatment storage box 12 is mixed with the hot water that is sucked from the tank 87 through the outflow pipe 93 into the pump 94 and jetted from the three types of nozzles 57, 59, and 60. Therefore, hot water containing the treatment liquid is sprayed on the hair. This injection is performed for time t9 (step S20).

After that, rinsing 3 is performed. In rinse 3
The short valve 95 and the long valve 96 are simultaneously turned on on the assumption that they can be rinsed lightly. Further, the treatment valve 104 is turned off (step S2
1). Then, rinsing 3 is performed for time t10 (step S22). Then, the hair-washing operation ends.

In the above embodiment, the automatic hair washer capable of washing so-called long hair has been described as an example. However, in the initial drainage, the work rate of the pump 94 is controlled by the inverter 106 to keep it low. The technical idea of is the water tank 51 in which only the nozzle link 55 for the crown and the nozzle link 58 for the neckline are provided in the water tank, and the nozzle 60 for cleaning the long hair portion is not provided.
Of course, it can be applied to a shallow type automatic hair washing machine.

Next, another embodiment of the present invention will be described. FIG. 12 is a sectional view of a crown nozzle link applied to another embodiment of the present invention. The top nozzle link 200 sprays washing water on a water pipe 201 having a substantially semi-arcuate shape formed along the head inserted when washing hair and a person to be washed arranged at a predetermined interval on the water pipe 201. It is composed of a plurality of nozzles 202, and the structure of the supporting means for supporting the nozzle link 200 for the crown is the same as that of the above-described embodiment (see FIG. 4).

Nozzle link 200 for the crown of this embodiment
Is characterized by the tip portion 207 of the water pipe 201. An enlarged tip of the water pipe 201 is shown in FIGS. 13 (a) and 13 (b). In FIG. 13A, the tip portion 207 of the water pipe 201 is not closed and the small hole 203 is opened. The size of the small hole 203 is, for example, the nozzle 2
02 (see FIG. 12) has a diameter of 0. It is about 10 mm, which is about 100 times as large as several mm. Further, in this embodiment, the tip portion 207 is bent inward to form the inner protrusion 204, and the tip portion of the inner protrusion 204 has a structure in which a ball 205 described later can abut without a gap.

A ball 205 for closing the small hole 203 is placed inside the tip portion 207 of the water pipe 201. The size of the ball 205 is designed to be smaller than the inner diameter of the water pipe 201 and larger than the diameter of the small hole 203. Further, a spring 206 is interposed between the ball 205 and the small hole 203. The spring 206 has a predetermined extension force.

According to the above structure, the ball 205 has the small hole 203 when the water is not supplied to the water pipe 201 or when the water pressure is less than the predetermined water pressure even if the water is supplied to the water pipe 201. Since it is urged away from
The small hole 203 is not blocked. On the other hand, when the wash water is supplied to the water pipe 201 at a water pressure higher than a predetermined water pressure,
As shown in (b), the water pressure exceeds the extension force of the spring 206, the ball 205 is pushed toward the small hole 203 side, and the small hole 203
Is blocked by the ball 203.

Water pipe 20 as such drainage adjusting means
The structure of the tip portion 207 of No. 1 is adopted not only in the nozzle link 200 for the crown but also in the nozzle link for the neckline. The structure of the tip portion 207 of the water pipe 201 as the drainage adjusting means described above is the structure having the ball 205 and the spring 206, but instead of this, a structure as shown in FIG. 14 may be used.

That is, in FIG. 14, the water pipe 301
A small hole 300 is formed at the tip portion 307 of the, and a valve 302 having a diameter larger than the diameter of the small hole 300 is provided inside thereof. This valve 302 has a spring property,
When the wash water is not supplied into the water pipe 301 or when the water pressure is lower than a predetermined water pressure, the state is as shown by a solid line 303, and when the water pressure is higher than the predetermined water pressure, a state is shown as a dotted line 304.

Next, the nozzle link 200 for the crown described above
The initial drainage operation of the automatic hair washer having the above will be described with reference to the flowchart shown in FIG. The operation before and after the initial draining operation is the same as the operation shown in FIG. 10.
In the initial drainage control shown in FIG. 15, the short valve 95 is used.
Is turned on. At this time, the long valve 96 and the drain valve 97 are still closed. Further, the timer T is turned on to start counting the operating time. Further, the pump 94 is turned on (step S200).

At this time, the pump 94 is the inverter 106.
Controls the output. That is, the output of the pump 94 is controlled to a predetermined low output such that the water pressure of the wash water supplied to the nozzle links 55 and 57 does not move toward the small hole 203 side against the force of the ball 206 (step S201). ). Therefore, the cold water remaining in the water pipe 200 or the like is drained from the small holes at the tips of the crown nozzle link 55 and the neckline nozzle link 58.

Then, this draining operation takes a predetermined time t1 '.
Is determined to have been performed during the period (step S202).
Then, the process proceeds to the next step. As described above, when the small holes 201 larger than the nozzles 57 and 59 are opened at the tip ends of the nozzle links 55 and 58 and the initial drainage is performed from the small holes 201, it is shorter than the initial drainage from the nozzles 57 and 59. Initial drainage can be performed.

Next, another embodiment will be described. FIG. 16 is a water channel diagram of an automatic hair washer according to still another embodiment. In FIG. 16, only the configuration X surrounded by a dotted line is different from the above-described embodiment, and the other configurations are the same. One end of the nozzle link 210 for the crown is connected to the pump 212 via the valve 211 for shorting, and the other end is connected to the cold water reflux pipe 213 via the valve A. Further, one end of the neckline nozzle link 214 is connected to the pump 212 via the short-circuiting valve 211, and the other end is connected to the cold water return pipe 213 via the valve B. Furthermore, long nozzle link 215

It is connected to 13.

Further, the head nozzle link 210, the neckline nozzle link 214 and the long nozzle link 21.
A cold water return pipe 213, to which 5 are connected via valves A, B and C respectively, extends into a tank 217.
Therefore, the cold water or the like flowing into the cold water return pipe 213 is guided to the tank 217. That is, the water channel of this embodiment has a circulation structure in which the cold water sent from the tank 217 and remaining in the pump 212 and the like returns to the tank 217 again.

Since the above structure is adopted, if the valves A, B and C are opened during the initial drainage, the cold water in the nozzle link 210 during the initial drainage is circulated back into the tank 217 and the water is not wasted. . In addition, in this way the tank 2
The amount of cold water returned to 17 is only a few cc, and the temperature of the hot water in the tank 217 hardly decreases due to the returned cold water.

FIG. 17 is a front view showing the detailed structure of the crown nozzle link shown in FIG. The head nozzle link 210 has a so-called double-support structure in which both sides of the water pipe 220 are held by the water tank side walls 221a and 221b, respectively. More specifically,
The nozzle link 210 for the crown is a water pipe 220 having a substantially semi-arcuate shape that is formed so as to follow the head that is inserted when washing hair.

The periphery of b is surrounded by housings 225a and 225b fixed to the water tank side walls 221a and 221b, respectively.
4a and 224b, respectively, housing 225
Bearings 226a and 226a and 225b are respectively held so as to be rotatably held with respect to a and b.
26b is fitted.

Rotary joints 227a and 227b are connected to the outer ends of the shaft pipes 224a and 224b, respectively, and a cleaning water supply pipe (not shown) is connected to the rotary joint 227a. 223a
The cleaning water is supplied to the water pipe 220 via. Then, the water is ejected toward the head from a plurality of nozzles 228 arranged in the water pipe 220 at predetermined intervals.

Further, a cold water return pipe (not shown) is connected to the rotary joint 227b, and a connecting member 223b,
Axial pipe 224b and rotary joint 227b
The cold water that has passed through is discharged to the cold water return pipe. At the outer ends of the shaft pipes 224a and 224b,
Further, pulleys 229a and 229b are fixed, respectively. A driving force, which will be described later, is transmitted to the pulleys 229a and 229b, and the respective pulleys 229a and 229b are rotated in the normal direction and the reverse direction within a predetermined angular range A1, whereby the shaft pipes 224a and 224b are rotated and are coupled thereto. The formed water pipe 220 is swung within the predetermined angle range A1.

Although the structure of the nozzle link for the crown has been described above, this embodiment also has the both-end supporting structure for the neck nozzle link and the long nozzle link as in the case of the nozzle link for the crown. ing. FIG.
8 is a flowchart showing initial drainage control of the automatic hair washer having the waterway diagram shown in FIG. The control before and after the initial drainage control is the same as the operation shown in FIG. 10.

After the crown nozzle link 210 reaches the lowermost portion by the operations from step S1 to step S3 in FIG. 10, the shorting valve 211 is turned on. At this time, the long valve 216 and the drain valve are still closed. Further, the timer T is turned on to start counting the operating time. Further, the pump 212 is turned on (step S210).

Further, the valves A and B are turned on. Therefore, the cold water guided to the nozzle links 210 and 214 by the pump 212 is drained to the cold water return pipe 213 and returned to the tank 217 (step S21).
1). Then, it is judged whether or not this draining operation is continued for a predetermined time t2 '(step S212).
As a result, if it is not continued, the above drainage operation is repeated until it is continued, and if it is continued, the valves A and B are turned off, and the initial drainage control ends (step S213).

As described above, in the automatic hair washer of this embodiment, the valve A and the valve B are turned on and the cold water is returned to the tank during the initial drainage of the cold water remaining in the pump or the like. Initial drainage can be done without waste. Besides, the present invention can be variously modified within the scope of the claims.
