With such a configuration, when water is not supplied, the temperature of the vacuum breaker 97 drops to about room temperature, and the regulating member 97e is moved by the biasing force of the bias spring 97c as shown in FIG. Pushed down to position. At this time, since no water pressure is applied, the valve body 97a opens the air inlet 97d. Since the communication path 97f is provided in the valve body 97a, the air is introduced from the air inflow path 97d to the hot water outlet 94t, and the water retained in the pipe downstream of the hot water outlet 94t is discharged from nozzle outlets 113d, 11 described later.

Even if a negative pressure is generated on the 4t side, the air inlet 97d is not opened. That is, the temperature-sensitive spring 97b
However, this is an operation restricting means that does not operate the vacuum breaker when the washing water temperature is equal to or higher than a predetermined water temperature.

Therefore, regardless of whether the vacuum breaker 97 that opens and closes due to a change in water pressure is provided near the pulsating unit 94 that changes the pressure of the washing water, the vacuum breaker valve is supplied while hot water is supplied as the washing water. The body 97a does not perform the opening and closing operation, and no generation of abnormal noise or the like occurs.

In the present embodiment, the bulk of the nozzle unit 110 is about 110 mm, and the bulk of the substantially flat surface 31p of the upper case is 120 mm, and the height having a margin of about 10 mm is as follows. This is because a tube for supplying water to the nozzle body 111 needs to move together with the nozzle body 111, so that this movable space is secured. This extra margin is a minimum requirement. If there is no extra margin, the tube is pressed by the upper case 31 and the nozzle unit 110, and the tube is eventually damaged.
The depth of the nozzle unit 110 is about 160 mm, which is also substantially equal to the depth of the upper case.

With reference to FIGS. 2 to 79, a description will be given of a blower blade constituted by the speed increasing cascade used in the present invention. FIG. 72 is a partially enlarged view of a blower blade formed of a conventional arc cascade, and FIG. 73 is a partially enlarged view of a blower blade formed of a speed increasing cascade. The circle in FIG. 72 indicates the size of the flow path cross-sectional area of the inter-blade flow path formed by the adjacent wings, and the size of the circle hardly changes at the time of inflow and at the time of outflow. Has been shown to be approximately constant.

The blade of FIG. 73 uses a speed increasing blade 137d, and the inclination of the chord represented by a straight line connecting the blade leading edge 137p and the blade leading edge 137q is the same as the rotation direction indicated by the arrow. The air that has entered from the wing leading edge 137p is bent in the same direction as the rotation direction, and flows out from the wing trailing edge 137q. The size of the circle in FIG. 73 indicates the cross-sectional area of the flow path, and the size of the circle decreases from the leading edge 137p of the blade to the trailing edge 137q of the blade. This indicates that the flow path cross-sectional area becomes smaller toward the downstream side, and the flow velocity increases. FIG. 74 shows the flow path cross-sectional area along the movement locus 137r of the center of the circle. Figure 72
In the same manner, the conventional arc wing shown in FIG. The length of the trajectory from the blade inlet to any position from the blade inlet is L, the length of the trajectory from the blade inlet to the position corresponding to the blade tip is Lw, and the area of the circle simultaneously touching the blade static pressure surface and the blade suction surface is L S, the cross-sectional area of a circle whose diameter is a line segment connecting two adjacent wing leading edges 137p is S _i . The flow path cross-sectional area ratio also decreases in the range of 0 <L / L _w <0.2 for the arc-shaped blades, but this is a contraction due to the blade thickness. Arc wing is L
In the region where / L _w > 0.2, the flow path cross-sectional area ratio is substantially constant, while in the case of the speed increasing blade, the flow rate continues to decrease almost linearly, and the flow path cross-sectional area ratio is about 0.5. It indicates that the average speed at the time of outflow is approximately twice as large as the average speed at the time of inflow.

Here, the theoretical background concerning the performance of the blower when the speed increasing blade is used will be described. FIG. 75 shows a velocity triangle representing a state at the time of the outflow of the impeller. Radial velocity at U _r is the impeller outlet, circumferential relative speed when V ₂ is the impeller outlet,
W ₂ is the relative velocity at the impeller outlet, R ₁ is an impeller inside diameter, R ₂
The impeller outer diameter, the beta ₂ represents the impeller outlet angle. Here, the flow rate is Q, the impeller height is H, the impeller rotation angular velocity is ω,
Assuming that the rotation speed of the outer periphery of the impeller is V _θ and the total pressure of the blower is P _t , the flow coefficient: φ, the pressure coefficient: ψ is φ = U _r / V _θ ＝ = P _t / ｛(ρ / 2) V _θ ² Ｕ U _r = Q / (2πR ₂ H) V _θ = R ₂ ω From the speed triangle at the exit of the impeller, U _r = W ₂ cos (π-β ₂ ) V ₂ = W ₂ sin (π-β ₂ ) Assuming that the radial velocity at the entrance of the vehicle is U _in , U _in = Q / (2πR ₁ H) = {φV _θ (2πR ₂ H)} / (2πR ₁ H) = φV _θ (R ₂ / R ₁ ) Letting the area ratio be ζ, W ₂ = U _in / ζU _r = ｛φV _θ (R ₂ / R ₁ ) / ζ} sin (π-β ₂ ) V ₂ = ｛φV _θ (R ₂ / R ₁ ) / Ζ｝ cos (π-
β ₂ ) Assuming that the absolute velocity in the circumferential direction of the blade outlet is V and slippage at the time of outflow is ignored, V = (V _θ + V ₂ ) = V _θＶ1 + φ (R ₂ / R ₁ ) cos (π-β ₂ ) ζ} (B) As is apparent from the formula B, the rotational speed of the air flowing out of the impeller changes depending on the area ratio の of the speed increasing portion, and the smaller the ζ, the faster the air flows out in the rotational direction. Have been. Since the work of such a centrifugal blower is based on the centrifugal force due to rotation, if the rotational speed at the time of outflow increases, the same effect as increasing the rotational speed can be obtained, and a large pressure head And high air volume can be obtained. In other words, by using the speed increasing wing, low rotation speed,
Even with a small impeller, a large pressure head and a high air volume can be obtained, and the device can be significantly reduced in size. In general, if the fan is designed to have a high air volume, the size of the scroll casing installed for converting the dynamic pressure of the impeller into static pressure needs to be large.
When the flow coefficient φ ′ taking into account the speed increasing effect of the speed increasing blade is defined as follows, φ ′ = U _r / V = φ / [{1 + φ (R ₂ / R ₁ ) cos (π−β ₂ ) /} ｝] It can be seen that φ ′ varies depending on the area ratio の of the speed increasing portion, and the smaller ζ, the smaller φ ′.

Since the outflow angle α at this time is represented by α = tan ⁻¹ (φ ′), it can be seen that α decreases as ζ decreases. The optimal design condition of the blower is when the outflow angle and the divergence angle of the scroll casing match, so by using the blades with the speed increasing effect, a large pressure head and a high air volume can be obtained, and the high air volume can be obtained. However, since the optimum spread angle of the scroll casing can be reduced, the size of the entire blower can be reduced. Similarly, the flow coefficient φ can be changed as follows.

[0097] _{φ = U r / V θ =} Q / (2πR 2 2 Hω) ... (1) flow rate as shown in equation (1) Factor: phi is a dimensionless number,
This is one index indicating the operating conditions of the blower. By applying the similarity rule for the blower, the characteristics of the blower operated under different conditions and sizes can be universally expressed. The flow rate Q as a device design variable is constant, and the impeller rotation speed N has an upper limit from the viewpoint of preventing vibration and noise, so that it can be made substantially constant. It is modified as follows equation (1), the left side of ^{_{πR 2 2 H = {Q /}} (2ω)} · (1 / φ) ... (A) formula (A) represents the volume of the impeller. From the right side, it can be seen that the volume of the impeller is proportional to the reciprocal of the flow coefficient. That is, if the operation can be performed with a large flow coefficient, the impeller can be downsized, so that the blower can be downsized. The conventional blower is φ = 0.06-0.
Considering that the fan is used at 09 (average: 0.075), if it can be operated at φ = 0.15 or more, the size of the blower can be reduced to about half or less. Also φ
Needless to say, if it is set to 0.18 or more, the size can be reduced to half of that of the smallest blower in the prior art. If it is possible to reduce the size of the blower by half, even if multiple blowout ports are provided to improve drying efficiency, the blowers can be individually set for multiple blowout ports without special branch ducts etc. Even if it is provided, it can be made sufficiently small. In this way, there is no need to consider the problem of pressure loss occurring in the duct, and it can be arranged at a required position according to the application, so that downsizing and improvement in drying efficiency can be achieved at the same time. Further, the design of the blower unit can be made very simple. Furthermore, when switching the flow path, of course, it is not possible to use multiple applications at the same time, but if the blower is provided independently, the necessary air can be blown at any time, so that it is excellent in comfort and usability. be able to.

FIG. 76 is a schematic view of an impeller. Here, impeller outer diameter: D ₂ = 56 mm, impeller inner diameter: D ₁ = 47 m
m, impeller height: H = 8 mm, and the number of blades is 36
It is a sheet. The ratio of the impeller inner diameter to the outer diameter: λ is set to about 0.85. When λ is reduced, noise such as wind noise can be reduced. Worsens. When λ is increased, the characteristics at high air flow are slightly improved. However, as the blade length is shortened, separation easily occurs inside the impeller, efficiency is reduced, and noise is increased. Taking these factors into consideration, λ is determined as a condition that allows the characteristics at the time of high air flow and the characteristics such as noise to be compatible.
The drive shaft of the motor is fixed to the motor receiving portion 8, and the motor torque is transmitted to the speed increasing impeller 6.

FIG. 77 and FIG. 78 show the main specifications of the speed increasing blade shape. The ratio の of the cross-sectional area of the flow passage of the speed increasing portion can be arbitrarily set depending on the blade shape. If ζ is small, a large speed can be obtained, so that a higher pressure and a higher air volume can be designed. However, the speed distribution at the time of the outflow of the impeller becomes large, so that the efficiency is easily lowered and the noise level is also increased. If ζ is large, the speed increasing effect is weakened, and it is difficult to improve the characteristics. Therefore, ζ ≒ is set to ζ ≒ 0.45 here.

FIG. 79 shows a drying fan 1 used in the present invention.
37 shows the measurement results of the hydrodynamic characteristics of No. 37 (the deodorizing fan 145). As compared with the results of the conventional blower using the arc blades shown at the same time, the characteristics have been extended to very high values of the flow coefficient. The result of actually designing and measuring the blower using these results shows that the impeller volume is about 22% (車 2.1) under the same design conditions as shown in FIG.
× 10 ⁴ /9.6×10 ⁴ ).

At the top of the front view in FIG.
A toilet flush switch "flow large" and "flow small" are provided. In this switch, “Large” on the left is a toilet flush switch for stool, and “Small” is a toilet flush switch for small use. At the front of the switch, a horizontally long projection is provided, and it is designed so that the operation switch can be recognized by design. Further, when a small accessory (a light object such as a hairpin) is temporarily placed on the upper surface of the remote controller, the projection also serves to prevent the accessory from dropping. Note that the toilet flush switch may not be provided, and only a switch for remotely controlling only the operation of the local cleaning device may be provided.

In addition, immediately below the toilet flush switch in FIG.
In order from the left side of the drawing, "stop switch", "butt cleaning switch (butt 1 washing switch)", "soft washing switch (butt 2 washing switch)", "bidet washing switch",
A "drying switch" is provided side by side. Since this portion is the most frequently used switch of the local cleaning device, the size of the switch button is increased to provide an easy-to-understand pictogram display. In addition, since each switch itself is square and substantially flush with the front surface of the remote control, small protrusions (stop switches) or embossed ( Other switches). In addition, these switches are different from the switches of the conventional remote controller, and have a form in which operation switches are continuous from end to end of the remote controller with quadrangular sides adjacent to each other. As a result, the size of each switch can be increased, so that the target at the time of operation is increased and the operation is facilitated. In addition, since the main operation switches are arranged in a line in a row for a low vision person, there is a design cohesion, and individual switches of a switch group can be identified by touching with a fingertip. It is very easy to operate.

Since the drying switch is arranged at the position of the light emitting LED in the embodiment of FIG. 52, in the embodiment of FIG. 53, the light emitting LED is built in behind the toilet flush switch.
LED light is emitted from the side wall light emitting part of the toilet flush switch.

Further, immediately below the main operation switch, a setting change switch unit for changing various set values for washing and drying is provided on the operation surface concealed by the lid.
Among the many setting change switches, when the lid is closed, the switch of move cleaning ON / OFF, massage cleaning ON / OFF, strength adjustment of water pressure, front / rear adjustment of nozzle cleaning position and liquid crystal displaying water pressure and cleaning position The display unit is exposed to the front side from the group of openings formed in the lid, and each switch can be operated. In addition, when the lid is opened, a power saving function setting switch, a nozzle cleaning switch (nozzle cleaning switch), a hot water temperature setting switch, a toilet seat temperature setting switch, a drying temperature setting switch, and a deodorizing on / off switch are provided. . Furthermore, in addition to the above-mentioned display of the water force and the washing position, the center liquid crystal display section also displays the setting conditions of the power saving mechanism, the numerical display of the hot water temperature, the numerical display of the toilet seat heating temperature,
The display shows the drying temperature (high, medium, low) and the presence or absence of deodorization.

The display contents of the liquid crystal display will be described in detail. The display of "Timer power saving" on the upper left of the display unit displays characters only when the power saving timer is switched on. Below that, "power saving time"
Then, a time selected from a plurality of set times of 3 hours, 6 hours, and 9 hours is selectively displayed. Below that, "Random power saving"
Displays characters only when power saving is selected. Omakase power saving means that the usage history of the local cleaning device is stored and the usage status is estimated by the device itself, and based on the estimated value, the device is automatically energized for human usage status, and de-energized or small when not in use. It is assumed that the amount of electricity is large. The water pressure display below the bar shows a bar line up to the water pressure selected by the user by operating the strength switch. Further, the washing position display thereunder indicates the washing position selected by the front / rear adjustment switch by the selection display of the nozzle ejection picture. The mark with a quadruple arc formed on the black circle between the water pressure display and the washing position display blinks for several seconds only when each operation switch is operated. If this display flashes when the switch is operated, it can be inferred that the remote control circuit is normal and the local cleaning device itself is abnormal. It is possible to presume that there is an abnormality, and there is an advantage that it is easy to identify the abnormal part. Subsequently, the hot water temperature display at the upper right of the liquid crystal display section digitally displays the set hot water temperature. The toilet seat heating temperature display thereunder digitally displays the set toilet seat heating temperature. The lower display of the drying temperature selectively displays the drying temperature selected from high, medium and low. Under the deodorizing display, a deodorizing character is displayed when the deodorizing switch is turned on.

As described above, of the various set values for washing and drying, only the set values that are often changed according to the user's preference can be changed without opening the cover, and only the changed portions are displayed from outside. It is visible. Thus, while many of the setting switches are covered by the lower portion of the lid, only the setting switches that are regularly used by the user are exposed to the outside to improve the usability.

The switches for turning on / off the move cleaning, turning on / off the massage cleaning, adjusting the water force, and adjusting the front / rear adjustment of the nozzle cleaning position are arranged in a line in a vertical line on the front surface side of the lid. In a switch in which two switches are paired to switch one function (a switch for adjusting the strength of water and a position for washing), the paired switches are connected by a protruding rib shorter than the switches. For this reason, there is a design cohesion, and individual switches in the switch group can be identified by touching with a fingertip, so that it is easy to operate even for people with low vision.

In the water pressure adjustment and the washing position adjustment, the switches are displayed as "strong" and "weak" on the surface of a small circular switch which can be pressed with a fingertip. , Are identified by character display on the liquid crystal display. Therefore, since no characters are written on the lid on which the switch is provided or the operation surface itself, the characters are not rubbed and erased during long-term use, and a refreshing appearance is obtained.

[0125] Among the setting change switches, the switch concealed by the lid when the lid is closed is not a mechanism for prohibiting the operation of the switch when the lid is closed, so that the closed lid is strongly pushed. The cover may bend and the switch may be pressed without your knowledge, and the setting may be changed regardless of the user's intention. In order to prevent this malfunction, a switch malfunction prevention section is provided on the back surface of the lid as shown in the cross-sectional view. The switch absorbing portion is configured such that when the cover is pushed into the switch side, the inside of the contact wall and the inside of the contact wall are brought into contact with the operation surface provided with the switch so that there is no further pushing. A switch housing for accommodating the switch head so that the switch is not pushed when the contact wall contacts the operation surface. By providing this switch malfunction prevention unit in correspondence with the switch concealed by the cover when the cover is closed, malfunction of the switch, for example, when the washing temperature or toilet seat temperature does not become high or low without the user's knowledge, is prevented. Can be prevented.

(Explanation of the main body attachment / detachment detection mechanism and the drainage mechanism) The present embodiment also includes the attachment / detachment mechanism for the main body of the local cleaning device proposed in Japanese Patent Application Laid-Open No. 8-326130. A detachable mechanism by engagement between a hook-shaped protrusion and a hook-shaped recess is disclosed in
Since the contents are exactly the same as those described in U.S. Pat. No. -326130, they are not described in the present application. In the drawing, reference numeral 1 denotes an engagement member fixed to a toilet (not shown), 2 denotes a drainage lever, 3 denotes a detachment detection bar, and 4 denotes a detachment detection switch. 1 has a protrusion 1a. The drainage lever 2 is formed in an L-shape by a water drainage urging portion 2a for urging the water drainage 74 and a guide portion 2b for operating along the inner wall surface of the lower case 35, and in the middle of the guide portion 2b. A draining handle 2c protruding outside from a draining lever opening 38 provided in the lower case 35, and a slide groove 2d are provided on the rear surface of the terminal end of the guide portion 2b. A spring (not shown) is disposed on the rotation shaft 3a of the attachment / detachment detection bar 3, and the attachment / detachment detection bar 3 is normally urged toward the attachment / detachment switch 4 by the torsion force of the spring. In addition, a protrusion 3 b is provided on the upper end surface of the attachment / detachment detection bar 3, and the protrusion 3 b is arranged so as to interfere with the lower end of the slide groove of the drainage lever 2. The attachment / detachment detection switch 4 is configured by a micro switch or the like, and the switch is turned on and off by turning a switch rod 4a.

Next, the operation will be described. When the apparatus main body 30 including the lower case 35 is attached to the engaging member 1 as shown in FIG. 66 (a), the attachment / detachment detection bar 3 is opened outward by the protrusion 1a against the torsion force of the spring. Keep in state. At this time, since the projection 3b is in contact with the slide groove 2d, the drainage lever 2 cannot be moved.
As shown in FIG. 66 (b), when the apparatus main body 30 is detached from the engaging member 1, the attachment / detachment detection bar 3 pushes the switch rod 4a of the attachment / detachment detection switch 4 by the torsion force of the spring, thereby turning on the switch. At this time, the projection 3b is

A movement margin is secured between the slide groove 2d and the drain groove 2d, and the drainage lever 2 can be operated. In this state, FIG.
When the handle 2c for draining operation is operated on the right side in the figure, the drain valve 74c of the drain plug 74 is pushed in by the drain plug urging portion 2a, and is separated from the rubber valve seat 74d. Then, water is discharged from a drain hole 39 (see FIG. 17) provided on the lower surface of the lower case 35. When the device main body 30 is reattached to the engaging member 1 as shown in FIG. 66 (d) with the drainage operation handle 2c forgotten to be returned, the protrusion 1a causes the detachment detection bar 3 to resist the torsion force of the spring. Then, the drainage lever 2 is pushed back to the original position by the projection 3b and the slide groove 2d while the attachment / detachment detection switch 4 is turned off. Therefore, even if the drainage lever 2 is forgotten to be returned to the original position after the drainage operation, the drainage operation is released by attaching the apparatus main body 30, and it is possible to return to the normal use state.

(Explanation of Operation) FIG. 55 is a block diagram of a water channel system, FIG. 56 is a time chart when the buttock 1 cleaning switch is operated, FIG. 57 is a flowchart of the pre-cleaning mode, and FIG. 4 shows a flowchart of mode 1. FIG. 67 shows a modification of the time chart.

When the user sits on the toilet seat 20, the human body detection sensor 165 detects the seating. In response to this detection signal, the mode shifts from the standby mode to the waste water mode. In the waste water mode, the energization of the solenoid valve 66 and the ceramic heater 71 is started, and the flow control subunit 92 is moved to a position where both the bypass port 92h and the outflow port 92i are in the open state. Butt 2 spout 113
e, the nozzle head 113 is washed by discharging water from all of the bidet ejection holes 113f and the washing port 122. When a predetermined time (15 seconds in this embodiment) elapses or a predetermined temperature (30 ° C. in this embodiment) has been detected by the limit thermistor 68, the power supply to the solenoid valve 66 and the ceramic heater 71 is stopped, and the water drain mode is set. It ends and shifts to the heat retention mode. In the heat retention mode, the ceramic heater 7
Only about 20 to 100 W of the 1200 Watt capacity is used. This is because the hot water storage type has a structure that allows natural convection, but the heat exchange unit 70 of the present invention is an instantaneous type and has a structure in which natural convection hardly occurs. If a full energization of 1200 W is performed, nucleate boiling (only a specific portion is heated) will occur, a heat pool will be generated, and hunting (hot water and cold water will be discharged at irregular intervals at the time of washing the buttocks) This is because there is a possibility of causing Since the amount of hot water is very small (about 10 to 20 cc in this embodiment),
Even if the wattage is low, the hot water in the heat exchange unit 70 does not cool down.

When the buttocks 1 washing switch 181 is pressed, the mode shifts from the warming mode to the pre-washing mode. In the pre-cleaning mode, the flow path of the flow path switching unit 100 is changed to the bottom one flow path 107.
a, and when this switching operation is completed, the flow control subunit 92 is shifted to the bypass hole 92n side, and at the same time, the energization to the electromagnetic valve 66 and the ceramic heater 71 is started,
The nozzle head 113 is cleaned from the cleaning port 122. The tapping temperature detected by the limit thermistor 68 is within a predetermined temperature range (30 ° C. to the set temperature + 2.5 ° C. in this embodiment) for a predetermined time (1.5 seconds in this embodiment) or for a predetermined time (this execution). After elapse of 5 seconds in the example), the mode shifts from the pre-cleaning mode to the nozzle body cleaning mode 1. In the nozzle body cleaning mode 1, energization of the nozzle motor 124 is started, and the nozzle body 111 is moved to a predetermined position. At this time, since the hot water remains discharged from the bypass port 92h, the body of the nozzle body 111 can be cleaned. When the movement of the nozzle body 111 to the predetermined position is completed, the mode shifts from the nozzle body cleaning mode 1 to the soft start mode. In the soft start mode, the flow control subunit 92 switches from the bypass hole 92n to the flow control groove 92p. The pulsating sub-unit 94 is driven in synchronization with the timing at which the rotor 92d of the flow regulating sub-unit 92 moves to a position three steps lower than the set flow rate, and the ass washing is started. When the movement of the rotor 92d to the position of the set flow rate is completed, the mode shifts from the soft start mode to the main cleaning mode. It should be noted that the pulsation subunit 9 is set at a stage several steps before the set flow rate.
When the pulsation sub-unit 94 is operated, a loud noise is generated at the start of the cleaning because air is in the cleaning water flow path at the time of starting the cleaning. This is for generating a pulsation at the stage of the flow rate. When the set flow rate is small and the pulsation subunit 94 cannot be operated three steps before, the pulsation subunit 94 is operated after reaching the set flow rate.

In the main cleaning mode, cleaning is performed at a set flow rate.

When the stop switch 184 is pressed, the mode shifts from the main cleaning mode to the nozzle body cleaning mode 2. In the nozzle body cleaning 2, the flow control subunit 92 is switched from the flow control groove 92p to the bypass hole 92n. When the transfer to the bypass hole 92n is completed, the nozzle motor 124 is energized and the nozzle body 1
11 is stored in the apparatus main body 30, and at the same time, the flow path switching unit 100 is shifted to a position where all the flow paths 117a, 117b, and 117c are opened. Also at this time, since the hot water remains flowing from the bypass hole 92n, the body of the nozzle body 111 is washed. When the storage of the nozzle body 111 is completed, the mode shifts from the nozzle body cleaning mode to the post-cleaning mode. In the post-washing mode, the flow control subunit 92 switches the flow path from the bypass hole 92n to the flow control groove 92p, and further drives the pulsation subunit 94 to cause the ejection holes 113d, 1
Hot water is jetted from the nozzle heads 13e and 113f.
Is washed. After a lapse of a predetermined time (3 seconds in this embodiment),
The energization of the solenoid valve 66 and the heater 71 is stopped, and the mode shifts from the post-washing mode to the drain / heat keeping mode. In the drain / heat keeping mode, first, the vacuum breaker 83 operates to discharge water remaining in the flow path from the vacuum breaker 83 to the flow control subunit 92. Then, the temperature of the stagnant water in the vicinity of the vacuum breaker 97 decreases, the urging force of the temperature-sensitive spring 97b weakens, and the vacuum breaker 97 operates,
The accumulated water from the flow control subunit 92 to the nozzle unit 110 is drained. In the local cleaning device of the present invention, since the pulsation unit 94 and the like are made of a resin material that is easy to cool, the water is drained immediately after the cleaning. When the user completes the task and leaves, the flow control subunit 9
2 shifts to the initial position where only the bypass flow path is opened. During this time, the control of the heat exchange unit 70 controls the above-described heat retention mode.

The accumulated water is discharged by opening the vacuum breaker valve 97a, which closed the air inflow passage 97d when there was a hydraulic pressure (during dynamic pressure), when the cleaning was completed and the static pressure was reached. Is an operation utilizing a so-called water pressure difference in the pipe, which is performed by introducing the pressure into the pipe. Instead, the temperature sensing spring is operated according to the temperature of the cleaning water, and when the cleaning water is at or above the predetermined temperature, the valve body 97a is closed so that the cleaning water is not discharged. At this time, it is also possible to open the valve body 97a and introduce the atmosphere from the air inflow passage 97d to discharge the stagnant water. However, the response speed is slower due to a change in temperature than a change in pressure of the washing water, so that it is not advisable to combine the vacuum breaker 97 with the operation limiting means based on the water temperature.

When the butt 2 switch 182 and the bidet switch 183 are operated, the butt 1 flow path 10 described above is operated.
The control is performed in which 7a is replaced with the bottom 2 flow path 107b and the bidet flow path 107c.

FIG. 59 is a conceptual diagram of the control of the heat exchange unit 70 in each of the modes during seating. In the waste water mode, feed-forward control (hereinafter referred to as F
F1). In order to perform this FF1 in as short a time as possible, excessive energization is performed with the target temperature set to 60 ° C.
The formula for calculating the amount of current at this time is: W (FF1) = α1 × (60−Thc) (W: input wattage, α1: gain, Thc: input water temperature detected by the thermistor 68).

It should be noted that the hot water temperature detecting thermistor 77 provides a 40
When the temperature is detected, the mode shifts from the waste water mode to the heat retention mode. In the warming mode, feedback control (hereinafter referred to as FB1) by the hot water temperature detecting thermistor 77 is performed. This F
In B1, excessive feedback control is performed with the maximum value of the heater power supply amount set to 20 W and the target temperature set to 60 ° C. During the heat retention mode, the butt 1 cleaning switch 181 (or the butt 2 cleaning switch 182, the bidet cleaning switch 1)
When the operation of 83) is performed, the mode shifts from the warming mode to the pre-washing mode to the post-washing mode. In the pre-wash mode to the post-wash mode, feed forward control (hereinafter, referred to as FF2) is initially performed. In the FF2, excessive energization is performed with the target temperature set to (set temperature + 20 ° C.). At this time, the calculation formula of the energization amount is: W (FF2) = α2 × (Tt + 20−Thc) (W: input wattage, α2: gain, Tt: set temperature, Tt
hc: incoming water temperature detected by the thermistor 68).

In the limit thermistor 82 (set temperature−5)
° C), the flow shifts to feedback control (hereinafter referred to as FB2) + feedforward control (hereinafter referred to as FF3). FB2 is feedback control by the hot water temperature detection thermistor 77 where target temperature = set temperature.
FF3 is a feedforward control in which a target temperature is set as a set temperature. At this time, the formula for calculating the amount of energization is: W (FB2 + FF3) = α3 × (Tt−Thc) + GP

I ′: integral gain (GI ′> GI), GD ′: differential gain (GD ′ <GD), WI ′: last integrated input wattage, Thh ′: last detected value of the hot water temperature detection thermistor 77). .

If the limit thermistor 82 detects the temperature between the set temperature and (the set temperature + 1.5 ° C.), the current supply amount up to the previous time is maintained. Further, when the limit thermistor 82 detects (set temperature + 1.5 ° C.) or more, FB2 + F
The control in F3 is performed.

By summarizing the above, up to (set temperature -5 ° C.) FF2 (set temperature -5) ° C) to (Set temperature -2.5 ° C) ············ FF3 + FB2 From (Set temperature -1.5 ° C) to set temperature ········· FF3 + FB3 From set temperature (Set temperature + 1.5 ° C) ··········· Maintains the previous energization amount (Set temperature + 1.5 ° C) and (Set temperature + 2.5 ° C) ··· FF3 + FB3 (Set temperature + 2.5 ° C) or more FF3 + FB2 As described above, the control formula is changed according to the temperature detected by the limit thermistor 82. This is because the local area is very sensitive and responds sensitively to overshoot. This is to reduce the In addition, the portion where the limit thermistor 82 is disposed can detect a stable temperature after stirring.

In the modified example of the time chart shown in FIG. 67, compared with the term chart of FIG. 56, at the time of detection of seating, waste water used last time is discharged from the bottom 1 flow path 107a, and the bottom 1 is used. When the cleaning switch 181 is pressed, the pre-cleaning operation of the nozzle is performed by injection from the bypass port 92h.

FIG. 60 shows experimental data obtained when the water supply was cut off during use using the local cleaning apparatus of the present invention under the above control.

From this data, it can be seen that the temperature becomes higher than the set temperature at about 1/3 of the originally required heat input during the water cutoff.
If the energization is continued as it is, the heat exchange unit 70 may be burned out. Therefore, when a state of about の of the originally required heat input continues for 5 seconds or more, it is determined that the water supply is cut off, and To stop the control.
