2. Description of the Related Art Conventionally, there has been known a sanitary washing apparatus for washing a local portion in a sanitary and comfortable manner by jetting washing water toward a local portion of a user. This sanitary washing device is mounted on a Western-style toilet 30 as shown in FIG. In the toilet 30, the rear end of the toilet seat 32 is generally rotatably attached to a dome-shaped main body 31. A water reservoir 33 is provided at the bottom of the main body 31, and a plurality of projections 35 are provided on the lower surface of the toilet seat 32 to abut on the peripheral edge 34 of the main body 31, whereby the toilet seat 32 is stably mounted on the main body 31. Is placed.

FIG. 8 shows a configuration of a conventional sanitary washing device 10 of a type which is additionally attached to an existing toilet 30 later. The sanitary washing device 10 includes the entire toilet device 3
A horizontal shaft 37 is attached to a rear portion of the frame body 36 to be mounted on the toilet body 0, and a toilet lid 38 and a rear end of a toilet seat 39 having a central portion opened are rotatably mounted on the horizontal shaft 37. A nozzle 43A for cleaning the toilet and a nozzle 43B for the bidet are attached to the lower side of the toilet seat 39.

Further, a control unit 40 for controlling the flow rate and pressure of the washing water is attached to the side of the frame 36, and an operation unit 41 is provided on the surface thereof. The operation unit 41 includes an oscillating cleaning selection switch 41A and a bidet selecting switch 41B for selecting the oscillating cleaning nozzle 43A and the bidet nozzle 43B, a stop button 41C, a pressure setting (water pressure adjustment) knob 41D, and the like. .

The washing water is supplied into the control unit 40 by a water distribution pipe 42 connected to an external pump (not shown) or the like, from which the washing water nozzle 43A or bidet nozzle 43A disposed behind the toilet seat 39 is provided. The water is sent to 43B and jetted out. Each of the nozzles 43A and 43B expands and contracts by the pressure of the cleaning water. That is, when not used, that is, when the cleaning water is not supplied, each nozzle 4
The 3A and 43B are completely housed inside the nozzle cover 45 by the urging force of a spring (not shown). When the cleaning water having a pressure greater than the tension of the spring is supplied, each of the nozzles 43A, 43B
Are extruded and arranged at predetermined positions.

[0009] On the lower surface of the toilet seat 39, as shown in FIG. 9, a projection 4 for stably holding the toilet seat 39 on the main body 31 of the toilet 30 when the sanitary washing device 10 is mounted on the toilet 30.
4 are provided. When attaching the sanitary washing device 10 to the existing toilet 30, the frame 36 is attached to the main body 31 of the toilet 30 after removing the toilet seat 32 of the toilet 30. At this time, the water distribution pipe 42 is connected to, for example, a water distribution pipe (not shown) of the washing water storage tank 2 arranged behind the toilet 30. When the toilet 30 is used, the toilet seat 39 of the sanitary washing device 10 is dropped on the main body 31 and seated thereon.

When the sanitary washing device 10 is used,
The pressure setting knob 41D (FIG. 8) for setting the jetting pressure of the washing water is set to a desired set value, and the washing water 43 is jetted out by selecting the nozzle 43A for washing the siri or the nozzle 43B for the bidet using the operating section 41. The spouted water allows the local area to be sanitarily and comfortably washed.

Further, in this sanitary washing device 10, FIG.
When the cleaning operation is started as shown in (1), the cleaning water is generally jetted for a fixed time regardless of the pressure set by the pressure setting knob 41D of the cleaning water. by this,
For example, even if the washing water is spouted by mischief of a child or the like, the washing water stops after a certain period of time, so that the surroundings can be minimized from being flooded.

[0009]

By the way, in the conventional sanitary washing apparatus 10, since the washing water is jetted for a certain period of time as described above, the jetting amount is different between when the water supply pressure is high and when the water supply pressure is low. That is, when the water supply pressure is high, the ejection amount increases, and when the water supply pressure is low, the amount of ejection decreases. Therefore, for example, when hot water is used in winter or the like, if the water supply pressure is high, after the hot water in the tank is all jetted out, cold water may be jetted out. In such a case, there is a problem that the user suddenly receives the cold water and feels discomfort.

Conversely, when the set pressure is low, the ejection of the washing water is stopped even though hot water remains in the tank. In this case, since the water supply pressure is low, cleaning once may be unsatisfactory, and the operating unit 41 may be operated again to eject cleaning water, which is inconvenient because it is troublesome twice.

Accordingly, the present invention has been made to solve the above-mentioned problem, and effectively utilizes the hot water in the tank.
The present invention proposes a sanitary washing device that does not cause discomfort to the user.

[0012]

In order to solve the above-mentioned problems, the present invention provides a tank for storing cleaning water, a heater for heating the cleaning water in the tank, and a cleaning tank for jetting the cleaning water in the tank. A nozzle, pressure control means for controlling the water supply pressure of the cleaning water, and pressure setting means for setting the water supply pressure are provided, and the cleaning water is ejected from the cleaning nozzle for a time corresponding to the set value of the water supply pressure. It is characterized by the following.

[0013]

As shown in FIGS. 1 and 2, the sanitary washing device 1 is provided with a hot water storage tank 13A. At the time of use, as shown in FIG. 4, each nozzle 11 has an ejection time T corresponding to the water supply pressure F set by the water supply pressure setting knob 15B.
Hot water in hot water storage tank 13A is jetted from A and 11B. With this, since the warm water is always blown out, the user does not feel uncomfortable. In addition, even if the child is mischievous, the surroundings can be minimized from being flooded.

[0014]

Next, an embodiment of a sanitary washing apparatus according to the present invention will be described in detail with reference to the drawings. In addition,
The same parts as those described above are denoted by the same reference numerals, and detailed description is omitted.

FIG. 1 shows a state in which the sanitary washing device 1 according to the present invention is mounted on an existing Western-style toilet 30 and the toilet seat 32 is raised. In this sanitary washing device 1, an oscillating washing nozzle 11 </ b> A and a bidet nozzle 11 </ b> B, which are arranged so as to eject cleaning water at different positions, are attached to a nozzle attachment portion 12 placed on the back side of the main body 31. ing.
FIG. 1 shows a state in which the nozzles 11A and 11B are housed,
That is, it indicates a non-use state.

The nozzle mounting portion 12 is provided on the periphery 3 of the toilet 30.
4 is securely attached to the rear end portion by a suction plate (not shown). The upper plate portion 12A of the nozzle attachment portion 12 is provided with coupling portions 12C on both ends. In addition, each nozzle 11
A connecting portion 13B is attached to the side surface of the control portion 13 arranged beside the main body 31 so as to adjust the height, so as to supply cleaning water to the A and 11B. The nozzle mounting portion 12 is mounted on the control portion 13 by connecting the connecting portion 12C to the control portion 13.

Hot water is supplied to the nozzle 11A and the nozzle 11B from the hot water storage tank 13A in the control unit 13 via pipes 14A and 14B. The pipes 14A and 14B are connected to the connecting portion 13B and the nozzle mounting portion 12.
Are located along the underside of the These pipes 14
Since the diameters of A and 14B are smaller than the gap between the toilet seat 32 and the main body 31, there is no possibility of being crushed.

The cleaning nozzle 11A and the bidet nozzle 11B extend and contract by the pressure of the cleaning water. That is, when not used, that is, when the cleaning water is not supplied, the nozzles 11A and 11B are completely housed inside the nozzle cover 12B by the urging force of the springs (not shown) attached to the nozzles 11A and 11B. Then, when the cleaning water having a pressure greater than the tension of the spring is supplied, the nozzle 11A for cleaning the iris and the nozzle 1 for the bidet are supplied.
1B is extruded and arranged at a predetermined position. The bidet nozzle 11B protrudes longer than the oscillating cleaning nozzle 11A.

FIG. 2 is a block diagram showing the configuration of the sanitary washing device 1. The suction pipe 53 connected to the external water storage tank 2 supplies cleaning water to the hot water storage tank 13A via the pump 52A. A motor 52B for driving the pump 52A is connected to the pump 52A. Also,
A heater 54 for heating the washing water is attached to the hot water storage tank 13A. The motor 52B and the heater 54 are controlled by the microcomputer 56, and a pressure setting knob 15B for adjusting the pressure of the washing water and a water temperature adjusting knob 15C for adjusting the temperature of the washing water are connected to the microcomputer 56. The microcomputer 56 has a pressure setting knob 15B.
Controls the number of revolutions of the motor 52B in accordance with the jetting pressure of the washing water set in the above, and controls the heater 54 in accordance with the temperature of the washing water set by the water temperature adjusting knob 15C.

Pipe 42 connected to hot water storage tank 13A
Is connected to a switching cock 55, which switches the washing water discharged from the hot water storage tank 13A and supplies it to the pipe 14A or the pipe 14B. Pipe 14
A and 14B are connected to an osiri cleaning nozzle 11A and a bidet nozzle 11B, respectively, whereby cleaning water is jetted from the osiri cleaning nozzle 11A or the bidet nozzle 11B.

As shown in FIG. 3, an operation section 15 is provided on the upper side of the control section 13 and includes a plurality of modes,
In this example, a relatively large rotary knob (rotary knob) 15A, a pressure setting knob 15B, and a water temperature adjusting knob 15C are arranged to select the "stop" mode, the "cleaning" mode and the "bide" mode. . Pressure setting knob 15B
The water supply pressure is increased or the water temperature rises as the water temperature adjustment knob 15C is rotated clockwise.

The rotary knob 15A is formed in a dome shape.
When D is turned to the “stop” mode position provided on the panel surface of the operation unit 15, the rotation of the rotary knob 15 </ b> A is temporarily stopped and the supply of the washing water is stopped as described later. Indicating line 15D
Is turned to the position of the “osiri cleaning” mode or the “bidet” mode, the rotation stops here, and the nozzle 11
The washing water is jetted from the nozzle A or the bidet nozzle 11B. In this example, the positions of the “washing” mode and the “bidet” mode are provided at positions 180 degrees apart from each other, and the position of the “stop” mode is provided in the middle.

In the sanitary washing device 1, when the "osiri washing" mode or the "bidet" mode is selected by operating the rotary knob 15A, the setting of the washing water pressure setting knob 15B is performed as shown in FIG. According to the pressure F, the microcomputer 56 (FIG. 2) determines the time T during which the cleaning water is jetted from the cleaning nozzle 11A or the bidet nozzle 11B. Then, the cleaning water is supplied at the set water supply pressure F only during the determined ejection time T.

FIG. 5 is a flowchart of a cleaning process 60 in the case of performing a cleaning operation in the sanitary cleaning device 1. When the "cleaning" mode or the "bidet" mode is selected, the water supply pressure F set by the pressure setting knob 15B is confirmed (step 61). Subsequently, the ejection time T is determined based on the confirmed set pressure F (step 62), and the washing water is supplied at the set water supply pressure F (step 63).

When the rotary knob 15A is set to the "stop" mode, the supply of the washing water is immediately stopped (step 6).
4) Until the "stop" mode is set, it is always determined whether or not the ejection time T determined in step 62 has elapsed (step 65). When the ejection time T has elapsed, the supply of the cleaning water is stopped.

The ejection time T is set so that the hot water in the hot water storage tank 13A is almost supplied and the cold water is not supplied. That is, when the set water supply pressure F is high, the amount of jet per unit time jetted from each of the nozzles 11A and 11B increases, so that the hot water storage tank 13A having a constant capacity is used.
The time during which all of the warm water in the tank is sent becomes shorter. On the other hand, when the set water supply pressure F is low, each nozzle 11A, 1
Since the amount of jet per unit time jetted from 1B is reduced, the time for sending all the hot water in the hot water storage tank 13A becomes longer. Therefore, the ejection time T is set to be shorter as the set water supply pressure F becomes higher. Then, when the washing water is jetted for the jetting time T, the hot water storage tank 13A
Only a little warm water is left inside. Thereby, even if a slight error occurs in the ejection time T for some reason, it is possible to prevent the cold water from being ejected from each of the nozzles 11A and 11B. The relationship between the set water supply pressure F and the ejection time T has been input to the microcomputer 56 (FIG. 2) in advance.

When the supply of the washing water is stopped due to the lapse of the ejection time T, the microcomputer 56 is reset by setting the rotary knob 15A to the "stop" mode position. This reset operation allows the washing water to be ejected again. Therefore, even though the rotary knob 15A is set to the ejection mode (the oscillating washing mode or the bidet mode), the washing water is not ejected. Natural feeling of operation can be eliminated.

As described above, the sanitary washing device 1 of the present embodiment can always jet hot water without jetting cold water by changing the jetting time T from each of the nozzles 11A and 11B according to the set water supply pressure F. Since it is possible, the user does not feel uncomfortable. Further, since the flush water stops after the squirting time T elapses, even if children or the like mischief, the toilet 3
It is possible to minimize the possibility that the area around 0 becomes flush.

When using the sanitary washing device 1, the toilet seat 32 is placed on the main body 31 as shown in FIG. As a result, the portion of the sanitary washing device 1 arranged in the main body 31 of the toilet 30 is almost invisible from the outside, and only the control unit 13 is arranged outside.

[0030]

As described above, the present invention provides a tank for storing cleaning water, a heater for heating the cleaning water in the tank, a cleaning nozzle for jetting the cleaning water in the tank, and a water supply pressure for the cleaning water. And a pressure setting means for setting the water supply pressure so that the cleaning water is ejected from the cleaning nozzle for a time corresponding to the set value of the water supply pressure.

Therefore, according to the present invention, by setting the ejection time according to the capacity of the hot water tank and the water supply pressure, the hot water can always be ejected, thereby preventing the user from feeling uncomfortable. . Further, since the ejection of the washing water is stopped after the elapse of the ejection time T, there is an effect that even if a child mischiefs and ejects the washing water, the surroundings can be minimized from being flushed. .
