Description

Description: FIELD OF THE INVENTION The present invention relates to a sanitary washing apparatus having a local washing function, and more particularly to a means for prioritizing a washing operation during re-disposal of hot water.

[Conventional technology]

2. Description of the Related Art Conventionally, a sanitary washing device for ejecting heated washing water to a local area for washing has been used as an integral or separate type with a toilet. As an example of integrating the toilet,
There are those described in, for example, JP-A-62-15689 and JP-B-63-26207, and various other structures have already been developed.

In these sanitary washing devices, the basic structure for local washing is to provide a nozzle that moves forward and backward from the inside of the casing integrated with the toilet to the washing position, and includes a heating tank that supplies hot water to the nozzle. is there. Such a structure is employed in most of the conventional sanitary washing apparatuses, and appropriate control of the temperature of hot water, optimization of the washing position by changing the stroke of noise, and the like are being further advanced.

A conventional sanitary washing device has a large power consumption because it includes a hot water tank with a built-in heater for heating hot water, a motor for driving a nozzle, and the like, and needs to be handled as an electric device using a general commercial power supply. On the other hand, when a toilet is integrated with a wash basin or bath tub such as a unit bath, the degree of bathing is large. No.

In order to solve such a problem, since a hot water supply facility is connected to the unit bath, an external water supply source and a hot water supply source can be connected to the nozzle device. For this reason, if the water supply and the hot water supply are appropriately mixed and discharged, there is no need to provide a hot water tank, and it is not necessary to energize the heater. Therefore, current consumption and electric power are also reduced, which is effective to some extent as a measure for preventing leakage, electric shock and the like.

By the way, in a sanitary washing device of a system of mixing hot and cold water using an external water supply source and a hot water supply source, when performing local cleaning, water in a hot water supply pipe connected to the hot water supply source is initially cooled, It is not suitable for spraying local water as washing water. When a certain amount of water is supplied from the hot water supply pipe, hot water is supplied from the main pipe of the hot water supply pipe. Therefore, until hot water is supplied from the hot water supply pipe, it is necessary to perform a hot water removal operation of discharging low-temperature water remaining in the hot water supply pipe from the hot water supply pipe to the outside.

During this hot water removal operation, that is, while the water that does not reach the predetermined temperature is being supplied from the hot water supply pipe, it is not preferable to perform the spouting from the washing nozzle because the water that feels cold is jetted to the local area. Therefore, control for stopping the cleaning operation during that time is performed. Then, when the temperature of the hot water supplied from the hot water supply pipe reaches a predetermined temperature, the hot water is stopped and the washing operation is enabled.

In this way, care is taken to prevent the cold water in the hot water supply pipe from being sprayed locally.

[Problems to be solved by the invention]

The present invention, after seating, when the hot water supply pipe is cooled without performing a washing operation for a while after the washing operation is enabled, perform re-discarding hot water until a suitable hot water temperature for comfortable use,
Furthermore, if a washing operation is performed in this re-disposal water,
An object of the present invention is to provide a comfortable use feeling without re-operation or waiting time of a user.

[Means for solving the problem]

The sanitary washing device of the present invention has a washing instruction from a user in a sanitary washing device provided with a re-discharging means for performing a prescribed re-discharging operation when the temperature of hot water is not suitable for cleaning. In some cases, the cleaning instruction is accepted even during the prescribed re-disposal operation.

In addition, the hot water from the hot water pipe (2d) and the valve (7a) for guiding the hot water to the hot water discharge pipe (2e) or the nozzle device, and whether or not the temperature of the hot water is suitable for cleaning, are estimated. And a control means for controlling the valve (7a) based on the control information. The control means sends the hot water to the nozzle device regardless of the estimation result when a cleaning command is issued from a user. The valve (7a) is controlled so as to be guided.

[Action]

When the washing operation is performed during the hot water dispensing operation, the washing operation is accepted or the washing water can be sprayed. Thus, it is possible to prevent the user from having to re-operate once in the washing preparation state or to have to wait until the washing becomes impossible and the washing can be performed.

〔Example〕

Hereinafter, the features of the present invention will be specifically described with reference to the embodiments shown in the drawings.

FIG. 1 is a circuit diagram showing a configuration example of a control system of a sanitary washing device according to the present invention, and FIG. 2 is a flowchart showing an operation of the present invention.

Before describing features of the present invention, a basic configuration will be described.

FIG. 4 is an internal plan view of the sanitary washing device showing one embodiment of the present invention.

The sanitary washing device has various devices incorporated in its casing 1, and these devices are fixed to a mounting board 1a. FIG. 5 shows the state of installation. In a unit bath provided with a bathtub A and a basin B integrally, a basin B is provided.
The casing 1 is fixed to a toilet body C arranged in front of the toilet bowl.

Returning to FIG. 4, the mounting board 1a includes a valve unit 2 connected to an external water supply source and a hot water supply source, a nozzle device 3 for ejecting cleaning water, and an operation unit for operating these devices.
4. A power supply unit (dry battery in this embodiment) 5 provided for driving the control system and a control circuit board 6 are fixed.

The valve unit 2 includes a water inlet pipe 2c and a hot water pipe 2d connected to external water supply pipes 2a and 2b, and has a built-in thermostat mixing valve having an automatic temperature control function. A hot water discharge solenoid valve 7a is provided in a flow path from the hot water supply pipe 2d to the thermostat mixing valve, and a water discharge solenoid valve 7b is incorporated downstream. FIG. 6 shows a water flow system, and a constant flow valve 7 is provided downstream of the water discharge electromagnetic valve 7b.
c, a vacuum breaker 7d and a distribution valve 7e are provided, respectively, and the water is distributed by the distribution valve 7e to the nozzle device 3 side and the waste water side. The hot water discharge pipe is connected to the hot water solenoid valve 7a.
2e is connected, and this is connected to the external hot water pipe 2f.

The hot water discharge solenoid valve 7a is provided for discarding the cold water in the hot water supply pipe 2b and the hot water supply pipe 2d, and detects the temperature of the hot water by a temperature sensor (a hot water thermistor TH ₁ described later) disposed upstream thereof. If the temperature is equal to or lower than a certain temperature, control is performed so that the hot water discharge electromagnetic valve 7a is opened to discharge hot water. Further, a nozzle-side hot water pipe 7f is connected to the distribution valve 7e, and the hot water is supplied to the nozzle device 3 and discharged to the bowl of the toilet body C at the same time. In this way, the purpose of discarding the hot water from the distribution valve 7e is to secure the flow rate because the thermostat mixing valve does not properly operate the temperature sensing unit unless the flow rate per unit time is a certain amount or more. It is. In other words, the operation of the temperature sensing part of the thermostatic mixing valve is insufficient only with the flow rate necessary for local cleaning, and therefore the flow rate is increased to compensate for this. In addition, the vacuum breaker
The overflow pipe 7g is connected to 7d, and discharges overflow water to the bowl of the toilet body C in the same manner as the nozzle side drainage pipe 7f.

The distributing valve 7e has a needle valve structure, and the nozzle-side drainage pipe 7f and the supply pipe 3a to the nozzle device 3 are moved by moving the valve shaft.
Are simultaneously changed. This operation is performed by a water force adjusting knob 4a provided in the operation unit 4, and a flexible shaft 4b using a wire or the like for transmitting a rotational operation force is provided between the water control knob 4a and the valve shaft of the distribution valve 7e. When the valve stem is moved by the water pressure adjusting knob 4a, if the flow rate on the nozzle device 3 side is reduced, the flow rate on the nozzle side drainage pipe 7f side increases,
Conversely, it is a matter of course that the distribution valve 7e is provided with a valve structure in which the flow rate to the nozzle device 3 decreases as the flow rate to the nozzle device 3 increases. As a result, a certain amount of hot water is discharged from the valve unit 2, the thermostat mixing valve is operated without any trouble, and flush water at a comfortable temperature can be sent to the nozzle device 3.

7 and 8 are sectional views showing the nozzle device 3. FIG.

The nozzle device 3 is a cylinder 3b having a supply pipe 3a connected to the upper end.
And the telescopic nozzle 3c, and has a configuration in which the telescopic nozzle 3c is advanced to the cleaning position by the water pressure of the cleaning water flowing from the supply pipe 3a. A piston portion 3d is formed at the upper end of the telescopic nozzle 3c, an internal flow path 3e is provided toward the tip, and an ejection hole 3f is opened at the tip. Further, a coil spring 3g is provided on the tip side of the piston portion 3d and the cylinder 3b, and when the water pressure decreases, the telescopic nozzle 3c can be moved in the storage direction by the urging force.

In such a configuration, when the washing water is fed into the cylinder 3b from the supply pipe 3a, the piston 3d receives the washing water and the telescopic nozzle 3c advances as shown in FIG. Then, at the same time as this advance operation, the washing water from the internal flow path 3e is discharged to the ejection hole 3f.
And can be cleaned locally. Further, after the supply of the washing water is stopped, the water pressure drops, so that the telescopic nozzle 3c is housed in the cylinder 3b by the urging force of the coil spring 3g as shown in FIG.

Further, the cylinder 3b is supported by the frame 8 in order to change the position of the ejection hole 3f of the nozzle device 3 and to move the cylinder 3b forward so that it can be used for anal cleaning and bidet use. As shown in FIG. 9, the frame 8 has an arc-shaped posture changing guide 8a on the back side, and a holding guide 8b on the front end side.
Is provided. The attitude change guide 8a receives the forked support arm 3h provided on the lower surface of the cylinder 3b,
8b slidably holds pins 3i provided on the left and right sides of the cylinder 3b. When the cylinder 3b is pulled out to the front side by these guides, as shown by the dashed line in FIG. 7, the cylinder 3b advances with a smaller inclination than that in the storage position.

The above-described advance operation of the cylinder 3b is performed by a rotation shaft 9 rotatably bridged over the frame 8 and a link rod 9a fixed to the rotation shaft 9 and having a distal end connected to the cylinder 3c. FIG. 10 (a) is a plan view schematically showing the rotating shaft 9 and its attached mechanism, and FIG. 10 (b) is a II line in FIG. 10 (a).
FIG. As shown, one end of the rotating shaft 9 is inserted into a sleeve 8c of the frame 8, and an arm 9b having an engaging pin 9c is fixed to the end. Also, sleeve 8c
A coil spring 8d is provided around the frame, and both ends of the coil spring 8d in the winding direction are engaged with engaging pins 9c and restraining pins 8e provided on the frame 8 as shown in FIG. 10 (b). For this reason,
When the rotating shaft 9 is rotated clockwise in FIG. 10 (b), the coil spring 8d is tightened by the movement of the engaging pin 9c, and an elastic reaction force is generated in the counterclockwise direction. Therefore, when the rotating shaft 9 is released, the rotating shaft 9 returns to the original position by the restoring force of the coil spring 8d.

The rotating operation of the rotating shaft 9 is performed by a switching knob 10 provided on the operation unit 4 and a wire 11 connecting between the switching knob 10 and the rotating shaft 9. FIG. 11 is a vertical cross-sectional view of the operation unit unit 4. A pulley 10b is provided at a lower end of a shaft 10a of the switching knob 10, and a wire 11 is attached to the pulley 10b so as to be wound up and released. On the other hand, a pulley 9d capable of winding the wire 11 is also fixed to the rotating shaft 9, and guide pulleys 12 and 13 for guiding the wire 11 from the switching knob 10 to the rotating shaft 9 are attached as shown in FIG. It is rotatably provided on the substrate 1a. In FIG. 7, if the winding direction of the wire 11 is such that the wire 11 is pulled when the switching knob 10 is rotated clockwise from the neutral position, the pulley 9 d rotates clockwise in FIG. I do. Therefore, the cylinder 3c is moved forward by the rotation shaft 9 and the link rod 9a, and can be set at the position shown by the one-dot chain line in FIG.

The guide pulley 12 has a fixed shaft as shown in FIG.
The fixed shaft 12a can be freely rotated to 12a.
It is fixed to the mounting board 1a by 12b. If the fixing bracket 12b is made movable by opening the elongated hole 12c in the fixing bracket 12b and fixing the screw 12, the position of the guide pulley 12 can be changed, and the tension of the wire 11 can be appropriately set. Further, if the holding plate 12e is provided along the peripheral surface of the guide pulley 12, even if the wire 11 is loosened, the wire 11 does not come off from the guide groove of the guide pulley 12.
It is a matter of course that such a configuration is provided to the other guide pulley 13 as well.

FIGS. 13 (a) and 13 (b) are cross-sectional views taken along lines II-II and III-III of FIG. 11, respectively.

On the shaft 10a of the switching knob 10, a holding mechanism for holding the switching knob 10 at the neutral, anal cleaning and bidet positions is provided. This holding mechanism, as shown in FIG.
A spring 14b incorporated in a sleeve 1c provided on a fixed seat 1b in the casing 1 and a ball 14c urged by the spring 14b are provided with respect to the restraining cam 14a formed as described above. Also,
The biasing force of the spring 14b can be appropriately set by an adjusting screw 14d screwed into the sleeve 1b. When the shaft 10a is rotated counterclockwise by such a holding mechanism as shown in FIG. 13 (c), the shaft 10a is held by the abutment engagement between the restraining cam 14a and the ball 14c, and is held as shown in FIG. 13 (e). Similarly, when rotated in the clockwise direction, the same holds. In FIG. 13, (a) is the neutral position,
When the shaft 10a rotates 90 degrees counterclockwise, it is set to the anal washing position, and when it rotates 90 degrees clockwise, it is set to the bidet position.

Further, a cam portion 15a is formed on the shaft 10a as shown in FIG. 13 (b), and a micro switch 16 is provided on the fixed seat 1c. The rotator 16b of the oscillating arm 16a provided in the micro switch 16 is arranged to face the peripheral surface of the cam portion 15a, and the rotator 16b abuts with the rotation thereof to operate the oscillating arm 16a,
The signal at this time is input to the control system. FIG. 13 (b) shows the case of the neutral position, in which the rolling element 16b is separated from the cam portion 15a and there is no input to the control system. FIG. 13 (d) shows the case of the anal cleaning position, in which the rolling element 16b hits the cam portion 15a and the swing arm 16a operates to input a signal to the control system, thereby performing anal cleaning. FIG. 13 (f) shows the bidet position, and a signal is input to the control system by the microswitch 16 as in the case of anal irrigation. Here, the wire 11 is wired so as to have an appropriate tension when in the neutral position, so that the wire 11 is loosened at the anal position and conversely pulled at the bidet position.

In the above configuration, when the switching knob 10 is rotated toward the anal irrigation side, the shaft 10a rotates as shown in FIGS. 13 (c) and 13 (d), and is held at a fixed position by the holding mechanism including the ball 14c. At the same time, the microswitch 16 is turned on, and the signal is input to the control unit of the control circuit board 6. Thereby, the water discharge electromagnetic valve 7b is opened, and the hot water appropriately mixed by the thermostat mixing valve is sent to the nozzle device 3. On the other hand, when the shaft 10a rotates in the counterclockwise direction in FIG. 13, since the wire 11 is in a loosening direction, no acting force for rotating the rotating shaft 9 is generated. Therefore, the cylinder 3b of the nozzle device 3 stops at the state shown in FIG. 8, and only the telescopic nozzle 3c advances to the position shown by the solid line in FIG. 7 by the water pressure of the supplied washing water. Subsequent to this advance, the washing water is injected from the ejection hole 3f, and the anal cleaning is performed.

When cleaning is completed, the switching knob 10 is returned to the neutral position, the microswitch 16 is turned off, and the water discharge electromagnetic valve 7b is closed by a signal input to the control system. As a result, the supply water pressure to the nozzle device 3 decreases, and the retractable nozzle 3c is housed in the cylinder 3b as shown in FIG. 8 by the restoring force of the built-in coil spring 3g.

On the other hand, when the switching knob 10 is rotated to the bidet side, the wire 11 is wound around the pulley 10b, whereby the pulley 9d starts rotating clockwise in FIG. 9 (b). Therefore, the rotating shaft 9 also rotates integrally and pushes the cylinder 3b forward by the link rod 9a. The cylinder 3b is guided by an arc-shaped posture changing guide 8a and a holding guide 8b, and takes a posture indicated by a dashed line in FIG. That is, the inclination is smaller than that of the cylinder 3b at the storage position, and the cylinder 3b advances forward. Simultaneously with such a change in the position of the cylinder 3b, the drain valve solenoid valve 7a
Cleaning water is supplied into the cylinder 3b by opening the water discharge electromagnetic valve 7b, and the telescopic nozzle 3c advances from the cylinder 3b.
Then, the supplied washing water is jetted at a position farther from the casing 1 than in the case of the anal washing, and can function as a bidet.

When the switching knob 10 is returned to the neutral position after cleaning is completed, the supply of the cleaning water is stopped, and the telescopic nozzle is operated in the same manner as in the case of anal cleaning.
3c is stored in cylinder 3b. On the other hand, since the wire 11 has no tension, the restraining force on the pulley 9d is also zero. Therefore, the rotating shaft 9 rotates counterclockwise in FIG. 9B by the restoring force of the coil spring 8d, and the cylinder 3b is stored in the original position.

As described above, by using the wire 11, the washing point of the nozzle device can be set at two places, and the nozzle device can be conveniently used for anal cleaning and a bidet as in the case of driving by a conventional electric motor or the like. In addition, since electric devices such as electric motors are reduced,
It can be used safely even if placed on the unit bus.

Next, an embodiment of the present invention shown in FIG. 1 will be described. In the figure, reference numeral IC1 denotes a central processing unit, which latches a solenoid valve 7a based on input signals from a thermistor TH1 for detecting a hot water temperature, a thermistor TH2 for detecting a water discharge temperature, a seating switch SW, and a microswitch 16. It has a function of controlling the operation of the solenoid LS1, the latching solenoid LS2 of the water discharge electromagnetic valve 7b, and the display LED.

That is, when a person sits on the toilet seat, the contact of the seating switch SW closes due to its weight or the like. Then, IC1 outputs a low level output to the discard terminal. After that, the output of the discard terminal is
After a certain period of time, that is, a sufficient time for turning on the hot water solenoid valve 7a, the level becomes high, and thereafter the hot water solenoid valve 7a is kept open by a self-holding function. In addition, a low level output is continuously output to the TH Tr terminal at regular intervals while a person is sitting. When the discard terminal goes low, the transistors Tr2, Tr8, Tr9 turn on. Other transistor T
r1, Tr7 and Tr10 remain off. As a result, a current flows from the upper side to the lower side in the drawing to the latching solenoid LS1 of the hot water solenoid valve 7a, and the latching solenoid LS1
Energize 1 in the opening direction. Then, the hot water discharge solenoid valve 7a is opened, and the hot water discharge to the hot water discharge pipe 2e is started. When the TH Tr terminal goes low, the transistor Tr6 is turned on, and the temperatures of the hot water and the discharged water detected by the hot water thermistor TH1 and the discharged water thermistor TH2 are input to the TH1 terminal and the TH2 terminal, respectively.

When the temperature of the hot water detected by the hot water thermistor TH1 reaches a predetermined temperature, the output of the hot water terminal goes low. The output of the discarding terminal goes to a high level after a certain period of time, that is, a sufficient time for turning off the discarding electromagnetic valve 7a, and thereafter, the discarding solenoid valve 7a is held in a closed state by a self-holding function. Then, when the output of the discard terminal becomes low level, the transistors Tr1, Tr7 and Tr10 are turned on, and a current flows from the lower side to the upper side in the drawing to the latching solenoid LS1 of the hot water solenoid valve 7a, and the latching solenoid LS1 is turned on. Energize in the closing direction. Then, the hot water discharge electromagnetic valve 7a is closed, and the hot water discharge to the hot water discharge pipe 2e is stopped. In the meantime, the display LED blinks, and as shown in FIG. 12, the display of “preparing” on the operation unit of the cleaning device blinks to indicate to the user that the water temperature has not reached the water discharge temperature. The display stops when the hot water is stopped by the temperature of the thermistor TH1 rising to the predetermined temperature.

After the initial hot water removal operation is completed, a predetermined time, for example, 5 minutes
The central processing unit IC1 has a timer function so that the hot water is re-discharged every minute.

The initial and redispersion operations are performed by the central processing unit IC1.
Is controlled based on the flowchart shown in FIG. That is, after the contact of the seating switch SW is turned on by the user sitting on the toilet seat, the switching knob 10 is turned from "stop" to "buttock" or "bidet" as shown in FIG.
The contacts of the microswitch 16 described above close. Thus, the flowchart of FIG. 2 starts. The central processing unit IC1 determines whether or not the hot water is being removed, and if not, determines whether or not the cleaning preparation is completed.
This is because the temperature of the hot water supplied from the hot water supply pipe, which is a condition for stopping the initial hot water dispensing operation even after the elapse of the predetermined time, does not rise, and the cleaning preparation is not completed when the cleaning preparation cannot be performed to save water. Means to exclude. When the cleaning preparation is completed, the water discharge electromagnetic valve 7b is opened, and the cleaning operation is performed according to the above-described procedure. If the hot water removal operation is being performed in the above step, it is determined whether or not the hot water removal operation is being performed. When the hot water is being re-discharged, the water discharge electromagnetic valve 7b is opened to immediately start the cleaning operation. When the re-watering operation is not being performed, that is, during the initial re-watering operation, the water discharging operation is disabled.

In this manner, the cleaning operation during re-discharging is immediately accepted, and the cleaning operation is performed. Although the temperature of the hot water used during the re-discharging may be slightly lukewarm, the re-discharging operation is performed every predetermined time, for example, every five minutes, so that the temperature of the hot water drops during that time is very small. It does not drop to the temperature where it feels cold. It is also possible to change the setting of the repetition time of re-discharging depending on the region.

Next, when water is to be discharged locally, the switching knob 10 is turned to the third position.
As shown in the figure, from the "stop" position, turn to the desired position of either "butt" or "bidet". When the switching knob 10 is switched to any position, as described above, the nozzle device 3 is switched to the "local cleaning" or "bidet" position, and the nozzle device 3 is interlocked with the cam portion 15a provided on the shaft 10a of the switching knob 10. As a result, the microswitch 16 operates to set the output of the discharge terminal of the central processing unit IC1 shown in FIG. 1 to a low level. The output of the spouting terminal goes high for a certain period of time, that is, a sufficient time after the water discharge electromagnetic valve 7b is turned on, and holds the water discharge electromagnetic valve 7b in an open state by a self-holding function. Then, when the output of the discharge terminal becomes low level, the transistors Tr4, Tr12 and Tr13 are turned on. The other transistors Tr3, Tr11, Tr14 remain off. As a result, the latching solenoid LS2 of the water discharge electromagnetic valve 7b has:
In the drawing, a current flows from the upper side to the lower side, and urges the latching solenoid LS2 in the opening direction. Then, the water discharge electromagnetic valve 7b is opened, the cleaning water is supplied to the cylinder 3b, the telescopic nozzle 3c is advanced, and the cleaning water is jetted to the local part from the tip.

When the cleaning is completed, the switching knob 10 is returned to the "stop" position.
Then, the microswitch 16 is turned off, and the output of the discharge / close terminal of the central processing unit IC1 becomes low level. The output of the discharge / close terminal goes to a high level after a lapse of a predetermined time, that is, a sufficient time for turning off the water discharge electromagnetic valve 7b, and thereafter, the water discharge electromagnetic valve 7b is held in a closed state by a self-holding function.
Then, when the output of the discharge closing terminal becomes low level, the transistors Tr3, Tr11, Tr14 are turned on, and a current flows from the lower side to the upper side in the drawing to the latching solenoid LS2 of the water discharge solenoid valve 7b, closing the latching solenoid LS2. Bias in the direction. Then, the water discharge electromagnetic valve 7b is closed, and the injection of the wash water from the extendable nozzle 3c is stopped.

The temperature of the washing water is physically controlled by the thermostatic mixing valve as described above.
The spouting thermistor TH2 is used to prevent the washing water from rising to a temperature at which the control is not performed correctly and the human body feels hot. That is, when the water discharge thermistor TH2 senses a temperature equal to or higher than the predetermined temperature, the output of the discharge / close terminal is set to low level, and the locking operation is performed so that the output of the discharge / open terminal does not become low level. The addition of such a safety device prevents an accident that must be avoided such as a burn.

In FIG. 1, IC2 denotes an element for making the power supply voltage of the dry cell constant, and IC3 denotes an element for monitoring the power supply voltage.

[Effect of the Invention] As described above, in the sanitary washing device of the present invention, by adopting the concept of re-disposable hot water,
For a predetermined period of time, the temperature of the washing water remaining in the hot water supply pipe and lowered in temperature can be set to a comfortable temperature. Furthermore, although the washing operation during the initial hot water rejection operation is not accepted, the washing operation during the re-hot water resolving operation is accepted and the washing operation is immediately performed, so that even if there is a possibility that the lubricating operation may be slightly lubricious, it is acceptable. Washing is performed using warm water of the temperature, and discomfort caused by waiting for a while is eliminated, and comfortable use can be performed.
