This flow control valve 21 controls the water flow rate by the flow rate of water, for example.

 The solenoid valve 22 is a normally closed on-off valve, and is opened based on a drive signal from the electronic control unit 14, and communicates the flow control valve 21 and the flow rate adjustment valve 23.

   The flow rate adjusting valve 23 is a valve that adjusts the water flow rate by tightening or loosening a valve rod fitted in a valve seat, for example, according to the operation of the operation unit 12, and communicates with the hot water tank 24. The hot water tank 24 stores hot water maintained at a predetermined temperature by a heater (not shown).

   The vacuum breaker 24 a is for preventing a reverse flow except for a vacuum generated in the water supply path, and communicates with the three-way switching valve 25 on the downstream side of the hot water tank 14. The three-way switching valve 25 selectively switches the communication state with one of the shower nozzle 26 and the bidet nozzle 27 based on a drive signal from the electronic control device 14 in accordance with a mode designated on an operation panel (not shown). It is.

The shower nozzle 26 and the bidet nozzle 27 are provided in the casing 30 (FIG. 5) of the warm water cleaning toilet seat device.
See) and are housed side by side. Since the shower nozzle 26 and the bidet nozzle 27 have the same structure, the structure of the shower nozzle 26 will be described below, and the description of the bidet nozzle 27 will be omitted.

 As shown in FIG. 2, the shower nozzle 26 is mainly composed of a cylinder 26a and a nozzle 26b. The cylinder 26 a includes a cylinder cylinder 31 and a cylinder lid body 36, and is attached to the casing 30. The nozzle 26 b includes a nozzle body 32, a first sleeve 33, a valve body 34, and a second sleeve 35.

 The cylinder cylinder 31 is formed in a substantially cylindrical shape, and the tip end side thereof is gradually reduced in diameter at the inclined portion 31a. Further, the tip end portion of the cylinder cylinder 31 is formed to be contracted at the step portion 31b. Note that the opening on the front end side of the cylinder cylinder 31 is formed in a flat circular shape whose upper and lower sides are substantially linear. On the other hand, a water channel 31 c connected to the three-way switching valve 25 is formed on the base end side of the cylinder cylinder 31.

 The nozzle body 32 is formed in a covered cylinder whose outer peripheral surface on the front end side has a substantially flat circular cross section corresponding to the opening of the cylinder cylinder 31, and is axially oriented with respect to the cylinder cylinder 31. It is slidably accommodated. A plurality of jet nozzles 32 a penetrating the upper wall surface in the substantially radial direction are formed at the tip of the nozzle body 32.

 The first sleeve 33 is attached to the proximal end side of the nozzle body 32. That is, the first sleeve 33 is formed in a substantially stepped cylindrical shape whose diameter is sequentially reduced through the inclined portion 33a and the stepped portion 33b toward the tip end, and the outer peripheral surface of the tip portion is the nozzle. The nozzle body 32 is provided integrally with the nozzle body 32 so as to be inserted and welded to the inner peripheral surface of the body 32.

 The nozzle body 32 and the first sleeve 33 (nozzle 26 b) are connected to the cylinder body 31 by a nozzle body spring 41 that is locked between the step portion 31 b of the cylinder body 31 and the inclined portion 33 a of the first sleeve 33. (Cylinder 26a) is housed in such a manner that it is biased toward the base end side (left side in FIG. 2). The nozzle main body 32 and the first sleeve 33 (nozzle 26b) protrude from the tip of the cylinder cylindrical body 31 (cylinder 26a) along the axial direction against the urging force of the nozzle main body spring 41 during driving described later. To do. At this time, when the inclined portion 33a of the first sleeve 33 and the stepped portion 31b of the cylinder cylinder 31 come into contact with each other, the protrusion of the nozzle body 32 and the first sleeve 33 (nozzle 26b) is regulated. Yes.

 On the inner peripheral surface of the first sleeve 33, there are provided a plurality of support walls 33c formed in a substantially plate shape on the center side at predetermined intervals in the circumferential direction, and on the center side of these support walls 33c. A guide wall 33d formed in a substantially cylindrical shape is integrally formed.

 The valve body 34 includes a valve portion 34a and a shaft portion 34b having a reduced diameter with an outer diameter equivalent to the inner diameter of the guide wall 33d on the distal end side of the valve portion 34a. The valve body 34 has a shaft portion 34 b inserted into the guide wall 33 d of the first sleeve 33, and is accommodated so as to be slidable in the axial direction with respect to the first sleeve 33. The valve body 34 is proximal to the first sleeve 33 by a valve spring 42 locked between the support wall 33c and the valve portion 34a of the valve body 34 on the outer peripheral side of the guide wall 33d. It is housed in such a manner as to be biased (left side in FIG. 2).

   The valve portion 34a of the valve body 34 is formed with a contact piece 34c projecting from the proximal end side along the axial direction. The second sleeve 35 is formed in a substantially cylindrical shape, and is fastened to the proximal end side of the first sleeve 33 in which the valve body 34 is accommodated. The second sleeve 35 is formed with a valve seat 35 a corresponding to the valve portion 34 a of the valve body 34.

 As shown in FIG. 3, when the nozzle body 32 and the first sleeve 33 (nozzle 26b) protrude from the tip of the cylinder cylinder 31 (cylinder 26a) against the urging force of the nozzle body spring 41 during driving, The valve portion 34 a of the valve body 34 is biased to the valve seat 35 a of the second sleeve 35 by the valve body spring 42. The distal end side of the first sleeve 33 and the proximal end side of the second sleeve 35, that is, the hollow portion of the nozzle body 32 and the outside are blocked.

 Further, as shown in FIG. 4, the inclined portion 33a of the first sleeve 33 abuts on the inclined portion 31a of the cylinder cylinder 31 during driving, and the protrusion of the nozzle body 32 and the first sleeve 33 (nozzle 26b) is restricted. Then, instead, the valve portion 34a of the valve body 34 is pushed out from the valve seat 35a, and the distal end side of the first sleeve 33 and the proximal end side of the second sleeve 35, that is, the hollow portion of the nozzle body 32 and the outside communicate with each other. Is done.

 The cylinder lid 36 has an outer diameter equivalent to the inner diameter on the base end side of the cylinder cylindrical body 31, and is mounted in a liquid-tight manner on the base end side of the cylinder cylindrical body 31. A concave portion 36 a that opens the water channel 31 c is formed on the tip end side of the cylinder lid body 36, and a pressure forming chamber R is formed between the concave portion 36 a and the first and second sleeves 33 and 35. .

 Further, a lid contact piece 36b that protrudes along the axial direction corresponding to the contact piece 34c of the valve body 34 is formed at the center of the recess 36a of the cylinder cover 36. As shown in FIG. 2, in a state where the nozzle 26 b is urged toward the proximal end side with respect to the cylinder cylinder 31 by the nozzle body spring 41, the lid contact piece 36 b The valve portion 34a of the valve element 34 is set so as to be pushed out from the valve seat 35a by contacting the contact piece 34c. Therefore, normally, the distal end side of the first sleeve 33 and the proximal end side of the second sleeve 35, that is, the hollow portion of the nozzle body 32 and the outside are in communication with each other.

 The operation unit 12 has a dial 12a, and the water flow rate by the flow rate adjustment valve 23 is adjusted to increase or decrease in accordance with the rotation operation. Further, when the dial 12a of the operation unit 12 is pivotally arranged at the [cleaning] position shown in FIG. 1, the water flow rate by the flow rate adjusting valve 23 is adjusted in a manner described later.

 When the dial 12a of the operation unit 12 is pivoted to the [cleaning] position, this state is output to the electronic control unit 14. The seating sensor 13 detects whether or not the toilet seat is seated according to a load applied to a toilet seat (not shown), and outputs the detection result to the electronic control unit 14. This is to prevent the shower nozzle 26 or the bidet nozzle 27 from being driven by an unintended operation in a state where the user is not seated on the toilet seat.

 The electronic control device 14 inputs each detection result by the operation unit 12 and the seating sensor 13 and suitably controls the electromagnetic valve 22 and the three-way switching valve 25 according to the state.

 In other words, when the electronic control unit 14 detects that the toilet seat is seated by the seating sensor 13, the electronic control unit 14 communicates with the water circuit unit 11 with the electromagnetic valve 22 energized. Then, the communication (shower nozzle 26 or bidet nozzle 27) of the three-way switching valve 25 is selectively switched according to a designated mode on an operation panel (not shown). That is, when the electromagnetic valve 22 is opened, the water pumped from the water supply source is introduced into the hot water tank 24, the hot water in the hot water tank 24 is pushed out, and the user is discharged from the tip of the shower nozzle 26 (bide nozzle 27). It is sprayed toward the buttocks (the female user's genital area). And injection of warm water is stopped by operation of a user's operation part.

 The internal timer of the electronic control unit 14 accumulates the time during which the electromagnetic valve 22 is opened, and this accumulated value T is stored in an internal register. This cumulative value is a cumulative value of the injection amount of hot water stored in the hot water tank 24. Thus, the cumulative value T of the time during which the solenoid valve 22 is opened reaches a predetermined value (specifically, when the amount of excrement removed from the local area by hot water becomes noticeable in the nozzle or the toilet). Then, the electronic control device 14 lights the LED 12L of the operation unit 12 and prompts the user to clean.

 In addition, when the electronic control unit 14 detects that the toilet seat is not seated by the seating sensor 13, the electronic control unit 14 shuts off the water circuit unit 11 by setting the electromagnetic valve 22 in a non-energized state. Further, when it is detected that the dial 12a of the operation unit 12 is pivotally arranged at the [cleaning] position, the electronic control unit 14 energizes the electromagnetic valve 22 regardless of the detection result by the seating sensor 13. As shown in FIG. And according to the above, the communication (shower nozzle 26 or bidet nozzle 27) of the three-way switching valve 25 is selectively switched. Thus, when the electronic control unit 14 detects that the dial 12a of the operation unit 12 is pivoted to the [cleaning] position, the electronic control unit 14 stores the cumulative opening time T of the electromagnetic valve 22 stored in the internal register. clear.

 In addition, although not shown in figure, the operation part 12 may be integrated with the main body of the warm water washing toilet seat apparatus, and may be a separate remote control apparatus. Needless to say, the dial 12a of the operation unit 12 may be changed to a push button.

 Next, operation | movement of this warm water washing toilet seat apparatus is demonstrated. In the state shown in FIG. 2, when the electromagnetic valve 22 and the three-way switching valve 25 are driven and water pressure is supplied to the shower nozzle 26 (the same applies to the bidet nozzle 27), the hot water pushed out from the hot water tank 24 is It flows into the pressure forming chamber R from the water channel 31 c of the cylinder cylinder 31. At this time, the pressure forming chamber R is supplied with water pressure based on the water flow rate that is increased or decreased by the flow rate adjusting valve 23 in accordance with the turning operation of the dial 12 a of the operation unit 12.

   When the cleaning water flows into the pressure forming chamber R, as shown in FIG. 3, the nozzle 26 b is against the urging force of the nozzle main body spring 41 along the axial direction based on the water pressure at that time. It protrudes from the tip of the cylinder 26a). At this time, the valve portion 34 a of the valve body 34 is urged to the valve seat 35 a of the second sleeve 35 by the valve body spring 42. The distal end side of the first sleeve 33 and the proximal end side of the second sleeve 35, that is, the hollow portion of the nozzle body 32 (nozzle 26b) and the pressure forming chamber R are blocked. Accordingly, at this time, the washing water does not flow into the hollow portion of the nozzle 26b.

   Further, when the nozzle 26b further protrudes from the tip of the cylinder cylinder 31 (cylinder 26a) along the axial direction against the urging force of the nozzle body spring 41, as shown in FIG. The inclined portion 33a of the first sleeve 33 abuts on the portion 31a, and the protrusion of the nozzle body 32 and the first sleeve 33 (nozzle 26b) is restricted. At this time, instead, the valve portion 34a of the valve body 34 is pushed out from the valve seat 35a, and the distal end side of the first sleeve 33 and the proximal end side of the second sleeve 35, that is, the hollow portion of the nozzle body 32 (nozzle 26b) and the pressure. The forming chamber R communicates with the forming chamber R. And the warm water which flowed into the hollow part of the nozzle main body 32 (nozzle 26b) spouts outside from the spout 32a. Note that the flow rate of the cleaning water ejected from the ejection port 32a is increased or decreased by the flow rate adjusting valve 23 in accordance with the water pressure supplied to the pressure forming chamber R, that is, the turning operation of the dial 12a of the operation unit 12. It is controlled by the water flow rate. In particular, in the present embodiment, when the dial 12a of the operation unit 12 is pivotally arranged at the [cleaning] position, the flow rate of the cleaning water ejected from the ejection port 32a is very small as shown in FIG. Is set to At this time, the electronic control unit 14 communicates with the water circuit unit 11 with the electromagnetic valve 22 energized regardless of the detection result of the seating sensor 13.

 When the cumulative value T of the time during which the solenoid valve 22 is opened reaches a predetermined value (specifically, when the amount of excrement removed from the local area by hot water becomes noticeable in the nozzle or toilet), The electronic control device 14 lights the LED 12L of the operation unit 12 and prompts the user to clean. When the user sees the LED 12L lit and cleans it, the dial 12a of the operation unit 12 is rotated to the [cleaning] position, the nozzle 26b of the shower nozzle 26 is projected, and the nozzle A small amount of washing water is ejected from the ejection port 32a of 26b. Accordingly, in cleaning the nozzle 26b itself, one hand is not occupied to pull the nozzle 26b out of the casing 30 (cylinder 26a), and therefore, for example, the scraping work of the nozzle 26b with the brush B is extremely efficient. Can be done. Moreover, since it is not necessary to directly touch the nozzle 26b by hand, it is hygienic. At the same time, the dirt thus rubbed off is washed away simultaneously by a small amount of washing water ejected from the nozzle 26b, and it is also possible to prevent the dirt from entering the nozzle 26b by the force of the washing water ejected. It can be a typical one.

 It should be noted that the place to be cleaned includes the toilet bowl and the casing 30 in addition to the nozzle.

 In the above-described embodiment, the accumulated value of the injection amount of the hot water stored in the hot water tank 24 does not depend on the accumulated opening time T of the electromagnetic stool 22, but the number of seating on the toilet seat and one seating. You may rely on the product of the amount of hot water used per hour (estimated value) or a value that uses both. In addition, the number of men who are sitting on the toilet seat and pissing is increasing, and in this case, there is no consumption of hot water. In this case, the cumulative value of the injection amount of hot water stored in the hot water tank 24 is calculated. May correct the number of seating in consideration of male use frequency.
