2. Description of the Related Art Conventionally, there has been known an automatic hair washer for washing hair by spraying warm water for washing onto the head and hair without manual intervention. However, the present applicant has filed Japanese Patent Application No. 4-41550. And the like have proposed prior art relating to this type of automatic hair washer. In the automatic hair washer according to the prior art, the hot water storage valve is opened to store hot water in the hot water storage tank. The hot water in the hot water storage tank is pumped out by a pump. During the hair washing operation, when the pump is driven and the upper nozzle valve, the lower nozzle valve, and the fixed nozzle are opened, hot water is supplied to the upper nozzle, the lower nozzle, and the fixed nozzle, respectively, and the hot water is jetted vigorously from each nozzle. Further, when the drain valve is opened, the hot water in the hot water storage tank is drained to the outside.

[0003]

The above-mentioned automatic hair washer is shipped to the market after a predetermined test operation. Before shipping, in consideration of water leakage caused by vibration during transportation, etc., the water in the pump was completely drained, and the hot water storage valve, upper nozzle valve, lower nozzle valve, fixed nozzle valve and drain valve were closed. Packed in state. Therefore, in a beauty salon or the like, after the installation of the automatic hair washer is completed and before starting, if the pump is not filled with water, that is, if so-called priming is not performed, the pump remains filled with air, and after the hair washing operation is started, the pump is started. It is temporarily run idle. The idle operation of the pump is not very preferable because it places a burden on the pump and may cause damage to the pump.

At present, priming is artificially performed from outside by opening a priming cock or the like of a pump. By the way, the pump is arranged at the bottom of the hair washer body. For this reason, the priming work has to be performed in a limited narrow work space, and is very troublesome for the installer. Therefore, an automatic hair washer capable of automatically priming the pump without performing priming work such as opening a priming cock or the like is desired.

The present invention has been made in view of the above technical problems, and an object of the present invention is to provide an automatic hair washer that automatically completes priming of a pump after the installation of the automatic hair washer is completed and before starting.

[0006]

Means for solving the problems according to the present invention are a hot water storage tank for storing hot water, a hot water supply path for guiding hot water to the hot water storage tank, a hot water storage valve for opening and closing the hot water supply path, and a hot water storage tank disposed below the hot water storage tank. A pump that pumps hot water inside, an outlet connected to one end below the hot water storage tank and the other end connected to the suction side of the pump, and cleans hair by injecting hot water pumped by the pump A nozzle, a supply path having one end connected to the discharge side of the pump and the other end connected to the nozzle, a nozzle valve for opening and closing the supply path, a drainage path branched from the supply path, a drainage valve for opening and closing the drainage path, When the hot water storage valve is opened and hot water is stored in the hot water storage tank before the automatic hair washer is installed and started, the nozzle valve and drain valve are opened in conjunction with this to open the pump and fill the pump. It is intended to include the means.

[0007]

In the above means for solving the above problems, when the hot water storage valve is opened and hot water is stored in the hot water storage tank by the valve control means after the installation of the automatic hair washer and before the start, the nozzle valve and the drain valve are operated in conjunction therewith. be opened. Then, the hot water supplied to the hot water storage tank flows into the suction side of the pump from the tank through the outflow passage. Thereby, the air filled in the pump escapes to the outside via the supply channel and the drain channel. As a result, hot water accumulates in the pump, and the pump is filled with priming water.

In other words, after the installation of the automatic hair washer and before the start, when the hot water supply is completed, the priming of the pump is automatically completed.

The valves V1 to V5 and the valves V61 and V71 each use an electromagnetic valve which can be opened and closed electrically. FIG. 4 is a block diagram showing an electrical configuration of the automatic hair washer. Referring to the figure, the automatic hair washer is provided with a microcomputer 200 as a control center. The microcomputer 200 includes a CPU, a data RAM, a program ROM, a timer, and the like, and performs control according to a program stored in the ROM in advance.

More specifically, the microcomputer 200
, Signals such as set values are input from key switches 71 corresponding to various keys provided on the operation panel 7. Further, the detection temperature of the water temperature detection thermistor Th and the detection outputs of the water level sensors LS and HS are input.

Further, the microcomputer 200 comprises:
By controlling the inverter 101, the pump 10 is driven at a predetermined work amount. In the above automatic hair washer, after a predetermined test operation is performed, the water in the pump 10 is completely drained,
In addition, the hot water storage valve V1, the upper nozzle valve V2, the lower nozzle valve V3, the fixed nozzle valve V4, and the drain valve V5 are closed and shipped to the market. Therefore,
After the installation of the automatic hair washer at the beauty salon, etc., before starting,
It is necessary to prime the pump 10 in order to prevent the pump 10 from being temporarily run idle after the hair washing operation is started. Therefore, the automatic hair washer is configured so that the pump 10 is automatically primed when hot water is supplied to the hot water storage tank 9 after the installation of the automatic hair washer is completed and before starting.

FIG. 5 is a flowchart showing the flow of the priming operation of the automatic hair washer. Referring to the figure, first, in step S1, when the hot water supply key is turned on after installation is completed and before starting, in step S2, hot water storage valve V1 is opened and hot water is supplied to hot water storage tank 9 via hot water supply path R1. Is done. In conjunction with this, the upper nozzle valve V2, the lower nozzle valve V3,
The fixed nozzle valve V4 and the drain valve V5 are opened.
Then, the hot water supplied to the hot water storage tank 9 flows from the outlet 91 of the tank 9 to the suction side of the pump 10 through the outflow path R2. As a result, the air filled in the pump 10 is reduced by the first to third supply paths R31 to R3.
3, and escape to the outside via the drain R4. As a result, warm water is accumulated in the pump 10 and priming into the pump 10 is completed.

When the water level in the hot water storage tank 9 reaches the upper limit in step S3, in step S4, the hot water storage valve V1, the upper nozzle valve V2, and the lower nozzle valve V
3. The fixed nozzle valve V4 and the drain valve V5 are closed to complete the hot water supply. As described above, when the hot water storage valve V1 is opened and hot water is stored in the hot water storage tank 9 before the automatic hair washer is installed and before starting, the upper nozzle valve V is linked with this operation.
2. Since the lower nozzle valve V3, the fixed nozzle valve V4, and the drain valve V5 are opened, when the hot water supply is completed, the priming of the pump 10 is automatically completed. Therefore, it is not necessary to open the priming cock or the like of the pump 10 to artificially start priming from the outside as in the related art, and the burden on the installer can be reduced.

Thus, for example, when the long hair course is selected and the hair washing operation is started, the upper nozzle link 20 swings along the top of the person to be washed, and the washing water flows from the nozzle 21 of the upper nozzle link 20. It is sprayed toward the head of the person being washed. In parallel with this, the lower nozzle link 50 also rotates, and the washing water is sprayed from the nozzle 51 of the nozzle link 50 toward the neck of the person to be washed. Further, washing water is sprayed from the fixed nozzles 71 to 73 toward the long hair portion of the person to be washed.

FIG. 6 is a diagram schematically showing a driving mechanism for driving the upper nozzle link and the lower nozzle link in conjunction with each other. Referring to the figure, this drive mechanism is configured such that two nozzle links, an upper nozzle link 20 and a lower nozzle link 50, are driven by one forward / reverse rotatable link motor LM. That is, the drive mechanism includes an arm 300 connected to the motor shaft MS of the link motor LM, a pulley 302 provided at the base of the support member 30 on the upper nozzle link 20 side, and a lower nozzle link 5.
Pulley 602 provided at the root of support member 60 on the 0 side
An endless pulley belt PB wound around, and a convex shaft 602a having one end connected to the tip of the arm 300 and the other end provided at a position eccentric from the rotation center of the pulley 602 on the lower nozzle link 50 side. And a link 310 connected to the

When the link motor LM rotates, the arm 3
00 rotates, and the rotational force is converted into a vertical movement of the link 310. The vertical movement of the link 310 causes the pulley 602 on the lower nozzle link 50 side to reciprocate within a certain angle range. Therefore, the lower nozzle link 50 reciprocally rotates within a certain angle range. Also, this lower nozzle link 5
The reciprocating rotational movement of the zero side pulley 602 is based on the pulley belt P
B is transmitted to the pulley 302 on the upper nozzle link 20 side via B. Therefore, the pulley 3 on the upper nozzle link 20 side
02 also rotates within a certain angle range, and as a result, the upper nozzle link 20 swings within a certain angle range.

By the way, even when the permanent liquid is dropped, rinsing is performed by an automatic hair washer in order to avoid rough hands due to the permanent liquid. Therefore, for example, the permanent liquid may be washed off while the rod is wound around the hair carelessly. In such a case, the rod is caught on the upper nozzle link 20 and the upper nozzle link 20 is overloaded. As a result, the rod may fly or be in a dangerous state. In consideration of such a situation, the drive mechanism is provided with an overload safety mechanism that stops the upper nozzle link 20 when the upper nozzle link 20 is overloaded.

FIG. 7 shows an example of the overload safety mechanism, and is a partially cutaway enlarged view of an X portion surrounded by a dashed line in FIG. Referring to the figure, a part of the peripheral surface of the motor shaft MS includes:
A recess 400 having a predetermined shape is formed. On the other hand, the arm 300 connected to the motor shaft MS has a ball 401 fitted into the recess 400 of the motor shaft MS, and the ball 40
A spring 402 that urges the motor shaft MS toward the motor shaft 1 with the bearing 1 facing the bearing hole 300a is incorporated. That is, the motor shaft MS and the arm 300 dent the ball 401
And are integrally rotatable.

In the above configuration, in a normal state where the upper nozzle link 20 is not overloaded, the arm 300
Since the ball 401 on the side is fitted and connected to the recess 400 of the motor shaft MS, the motor shaft MS and the arm 300 rotate integrally. On the other hand, when a certain torque is applied to the upper nozzle link 20, the ball 401 is pressed by the sliding contact surface of the recess 400 and sinks into the arm 300 against the urging force of the spring 402. As a result, the connection between the motor shaft MS and the arm 300 is released, and the motor shaft MS idles. Therefore, the upper nozzle link 20 stops without swinging.

FIG. 8 shows another example of the overload safety mechanism, and is an enlarged sectional view of a portion Y surrounded by a dashed line in FIG.
FIG. 2A shows a state viewed from the front side, and FIG. 2B shows a state viewed from the right side.
Referring to FIG. 8, pulley 602 on lower nozzle link 50 side
And a part of the water pipe 603 has magnets MG1 and MG2, respectively.
The pulley 602 and the water pipe 603 are coupled by the attraction of the magnets MG1 and MG2,
It can rotate integrally.

According to this configuration, when a constant torque is applied to the upper nozzle link 20, the magnets MG1, MG2
Is released, and the connection between the pulley 602 and the water pipe 603 is released. As a result, the upper nozzle link 20 stops. Pulley 6
After the connection between the water pipe 02 and the water pipe 603 is released, the link 31
When 0 is turned, the magnets MG1 and MG2 are attracted again at the correct position, and the pulley 602 and the water pipe 603 are connected.

By providing the overload safety mechanism shown in FIG. 7 or FIG. 8, when the rod is hooked on the upper nozzle link 20, the upper nozzle link 20 stops, so that the rod does not fly and the safety is improved. Can be secured. The same effect can be obtained by providing the overload safety mechanism shown in FIG. 8 on the pulley and the water pipe of the upper nozzle link. It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made within the scope of the present invention.

For example, in the above embodiment, the present invention is applied to an automatic hair washer having a deep water tank provided with a fixed nozzle for a long hair portion, but the present invention has no fixed nozzle. Alternatively, the present invention may be applied to an automatic hair washer using a water tank having a relatively shallow depth.
