A seal packing 3 is attached to the stopper portion 6. A flow path 7 that communicates with the ejection hole 5 from the rear end surface is formed inside the nozzle body 1.

  On the other hand, the nozzle holder 2 includes a small-diameter portion on the front end side and a large-diameter portion on the rear end side. Thus, a stopper surface 2b is formed between the small diameter portion and the large diameter portion, with which the stopper portion 6 can abut via the seal packing 3. A cleaning water inlet 8 is provided on the rear end surface of the nozzle holder 2, and an opening 2 a is provided on the front end surface of the nozzle holder 2.

  The nozzle body 1 is movably inserted into the nozzle holder 2 so that the tip portion protrudes from the opening 2a.

  The return spring 4 is disposed between the stopper portion 6 of the nozzle body 1 and the periphery of the opening 2 a of the nozzle holder 2, and biases the nozzle body 1 toward the rear end side of the nozzle holder 2.

Further, a magnet 9 is provided at the tip of the nozzle body 1.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a perspective view showing a state in which a toilet apparatus according to an embodiment of the present invention is mounted on a toilet.

  As shown in FIG. 1, the toilet apparatus 100 is mounted on the toilet bowl 600.

  The toilet device 100 includes a main body 200, a remote operation device 300, a toilet seat 400, and a lid 500.

  A toilet seat 400 and a lid 500 are attached to the main body 200 so as to be freely opened and closed. Further, the main body 200 is provided with a cleaning water supply mechanism including a nozzle unit 700 and a control unit is incorporated. The control unit of the main body 200 controls the cleaning water supply mechanism based on a signal transmitted by the remote operation device 300 as will be described later. Further, the control unit of the main body 200 controls a heater (not shown) built in the toilet seat 400, a deodorizing device (not shown) provided in the main body 200, a hot air device (not shown), and the like. Also do.

  FIG. 2 is a schematic diagram showing an example of the remote control device 300 of FIG. As shown in FIG. 2, the remote operation device 300 includes a plurality of LEDs (light emitting diodes) 301, a plurality of adjustment switches 302, a butt switch 303, a cleaning switch 304, a stop switch 305, a bidet switch 306, a drying switch 307, and a deodorizing switch. 308.

  The user operates the adjustment switch 302, the butt switch 303, the cleaning switch 304, the stop switch 305, the bidet switch 306, the drying switch 307, and the deodorizing switch 308. Thereby, the remote operation device 300 wirelessly transmits a predetermined signal to a control unit provided in the main body 200 of the toilet device 100 described later. The control unit of the main body unit 200 receives a predetermined signal wirelessly transmitted from the remote operation device 300, and controls the washing water supply mechanism and the like.

  For example, when the user operates the butt switch 303 or the bidet switch 306, the nozzle portion 700 of the main body 200 in FIG. 1 moves and the washing water is ejected. By operating the stop switch 305, the ejection of the washing water from the nozzle unit 700 is stopped.

  Further, by operating the drying switch 307, warm air is jetted from a warm air device (not shown) of the toilet device 100 to a local part of the human body. By operating the deodorizing switch 308, the deodorizing device (not shown) of the toilet apparatus 100 performs the deodorization of the surroundings.

  When the user operates the adjustment switch 302, the position of the nozzle part 700 of the main body part 200 of the toilet apparatus 100 of FIG. 1 changes, the temperature of the washing water ejected from the nozzle part 700 changes, The pressure of the cleaning water ejected from the nozzle unit 700 changes. A plurality of LEDs (light emitting diodes) 301 are lit as the adjustment switch 302 is pressed.

  FIG. 3 is a schematic diagram illustrating the configuration of the main body 200 of the toilet apparatus 100 according to the present embodiment.

  As shown in FIG. 3, a branch tap 25 is inserted in the water pipe 201. Further, a strainer 26, a check valve 27, a constant flow valve 28, a water stop electromagnetic valve 29, a flow sensor 30 and a temperature sensor 32a are sequentially provided in a pipe 202 connected between the branch tap 25 and the heat exchanger 31. It is inserted. Further, a temperature sensor 32 b and a pump 33 are inserted in a pipe 203 connected between the heat exchanger 31 and the switching valve 34.

  First, purified water flowing through the water pipe 201 is supplied to the strainer 26 by the branch tap 25 as cleaning water. The strainer 26 removes dust and impurities contained in the cleaning water. Next, the check valve 27 prevents the cleaning water from flowing backward in the pipe 202. Then, the flow rate of the cleaning water flowing in the pipe 202 is kept constant by the constant flow valve 28.

  A relief pipe 204 is connected between the pump 33 and the switching valve 34, and a relief water pipe 205 is connected between the water stop electromagnetic valve 29 and the flow sensor 30. A relief valve 206 is inserted in the relief pipe 204. The relief valve 206 opens when the pressure in the pipe 203, particularly on the downstream side of the pump 33, exceeds a predetermined value, and prevents problems such as damage to the equipment and disconnection of the hose at the time of abnormality. On the other hand, of the wash water supplied with the flow rate adjusted by the constant flow valve 28, the wash water not sucked by the pump 33 is released and discharged from the water pipe 205. Thereby, a predetermined back pressure acts on the pump 33 without being influenced by the water supply pressure.

  Next, the flow rate sensor 30 measures the flow rate of the cleaning water flowing in the pipe 202 and gives the measured flow rate value to the control unit 40. In addition, the temperature sensor 32 a measures the temperature of the cleaning water flowing in the pipe 202 and gives a temperature measurement value to the control unit 40.

  Subsequently, the heat exchanger 31 heats the cleaning water supplied through the pipe 202 to a predetermined temperature based on the control signal given by the control unit 40. The temperature sensor 32 b measures the temperature of the cleaning water heated to a predetermined temperature by the heat exchanger 31 and gives a temperature measurement value to the control unit 40.

  The pump 33 pumps the cleaning water heated by the heat exchanger 31 to the switching valve 34 based on a control signal given by the control unit 40. The switching valve 34 supplies cleaning water to any one of the bottom nozzle 35, the bidet nozzle 36, and the nozzle cleaning nozzle 37 of the nozzle unit 700 based on a control signal given by the control unit 40. As a result, cleaning water is ejected from any one of the buttocks nozzle 35, the bidet nozzle 36 and the nozzle cleaning nozzle 37.

  The control unit 40 performs the heat stop electromagnetic valve 29, heat exchange based on the signal transmitted wirelessly from the remote control device 300 of FIG. 1, the measured flow rate value given from the flow sensor 30 and the temperature measured value given from the temperature sensors 32a and 32b. A control signal is given to the device 31, the pump 33 and the switching valve 34.

  Next, the bottom nozzle 35 of the nozzle unit 700 in FIG. 3 will be described. FIG. 4 is a cross-sectional view of the bottom nozzle 35 of the nozzle portion 700 of FIG. The only difference from the conventional example shown in FIG. 5 is that no magnet is provided at the tip of the nozzle body 1. 4 are the same as those in the conventional example, and the description thereof is omitted.

  Next, the operation of the butt nozzle 35 in FIG. 4 will be described.

  First, as shown in FIG. 4B, when the supply of cleaning water is started from the cleaning water inlet 8 of the nozzle holder 2, the nozzle body 1 resists the elastic force of the return spring 4 by the pressure of the cleaning water. Progress gradually in the direction of arrow X.

  The washing water flows out from the ejection holes 5 through the gap between the outer peripheral surface of the nozzle body 1 and the inner peripheral surface of the opening 2 a of the nozzle holder 2 and the flow path 7 of the nozzle body 1.

  When the nozzle body 1 further advances, the stopper portion 6 comes into watertight contact with the stopper surface 2b of the nozzle holder 2 via the seal packing 3, as shown in FIG. Thereby, a gap between the outer peripheral surface of the nozzle body 1 and the inner peripheral surface of the opening 2 a of the nozzle holder 2 from the gap between the outer peripheral surface of the stopper portion 6 of the nozzle body 1 and the inner peripheral surface of the nozzle holder 2. The flow path leading to is blocked. Therefore, the washing water in the nozzle holder 2 is ejected vigorously only from the ejection hole 5 through the flow path 7 in the nozzle body 1 to perform local washing of the human body.

  Next, as shown in FIG. 4A, when the cleaning water is not supplied from the cleaning water inlet 8 of the nozzle holder 2, the nozzle body 1 moves backward in the direction opposite to the direction of the arrow X by the elastic force of the return spring 4. . As a result, the nozzle body 1 is stored deeply in the nozzle holder 2 so as to be flush with the opening 2 a of the nozzle holder 2.

  It is difficult to grasp and pull out the nozzle body 1 housed in this way. Therefore, when the user operates the clean switch 304 of the remote control means 300, the control unit 40 operates the water shut-off electromagnetic valve 29, the pump 33, the switching valve 34, and the heat exchanger 31 in the same manner as when the weight switch 303 is operated. Then, supply of cleaning water is started from the cleaning water inlet 8, and the nozzle body 1 is advanced in the X direction by the water pressure of the cleaning water.

  By the way, when the nozzle main body 1 moves forward to a position where it completely protrudes, the seal packing 3 comes into close contact with the stopper surface 2b, and the washing water is ejected vigorously from the ejection hole 5 and jumps out of the toilet and wets the floor surface. There is a risk. Therefore, it is necessary to stop the supply of cleaning water before the nozzle body 1 protrudes completely. Therefore, the supply of the cleaning water is stopped when the predetermined time stored in the control unit 40 in advance as the time when the nozzle body 1 does not completely protrude after the supply of the cleaning water is started inside the control unit 40. To do.

  Here, the flow rate of the cleaning water supplied to the cleaning water inlet 8 is the supply flow rate R [cc / min], and the inside of the outer peripheral surface of the nozzle body 1 and the opening 2a of the nozzle holder 2 until the nozzle body completely protrudes. The flow rate of the cleaning water leaking from the gap between the peripheral surface and the ejection hole 5 is the leakage flow rate S [cc / min], and is formed on the rear end side of the nozzle holder 2 when the nozzle body 1 is completely projected. Assuming that the volume of the space 9 is the holder volume H [cc], if the time until the nozzle body 1 protrudes completely is the protrusion time T0, it can be expressed as shown in Expression (1).

T0 [s] = H ÷ {(R−S) ÷ 60} (1)
Specifically, if the supply flow rate R of the toilet apparatus of the present embodiment is 400 [cc / min], the leakage flow rate S is 100 [cc / min], and the holder volume H is 30 [cc / min], the protrusion time T0 is 6 [s].

  That is, the control unit 40 is provided with a time measuring means 41 for measuring the supply time t from the start of the supply of the washing water, and the supply time t is set to the protrusion time T0 stored in advance as a predetermined time. If the supply of cleaning water is controlled to stop at the moment when it reaches, the nozzle body can be protruded while preventing the cleaning water from being ejected.

  In addition, since the protrusion time T0 varies depending on the following factors, it is better to determine in consideration of this point. First, the holder volume H and the leakage flow rate S are determined by only the nozzle dimensions. Therefore, if the molding error of the nozzle body 1 and the nozzle holder 2 can be made sufficiently small, the degree of influence thereof can be made sufficiently small. Next, regarding the supply flow rate R, even if the control amount P given to the pump 33 by the control means 4 is a fixed value, the variation occurs due to the variation in the performance of the pump 33. When the pump 33 is driven by a DC motor, the variation in the winding diameter of the motor is relatively large, which affects the variation in the supply flow rate R. If the variation in the winding diameter of the motor is ± 7%, the minimum projecting time Tmin can be expressed approximately by the equation (2).

Tmin [s] = 0.93 × T0 (2)
If the specific example is applied, the shortest time Tmin is 5.6 [s]. Further, considering the margin of 0.6 [s] as a consideration for the variation of the holder volume H and the leakage flow rate S that are ignored because they are sufficiently small, the cleaning water is 5.0 [s] after starting the supply of the cleaning water. If the supply is controlled to stop, even if the performance of the nozzle unit 700 and the pump 33 varies, it is possible to prevent the cleaning water from being ejected and to protrude the nozzle body.

  If the control unit 40 controls the pump 33 so that the detected flow rate Q of the washing water detected by the flow rate sensor 30 and the supply flow rate R assumed in advance coincide with each other, the nozzle body 1 regardless of the aforementioned variation. Protrusion can be performed. In this case, even if the back pressure on the temporary side of the pump fluctuates, the supply flow rate R is reliably secured, so the toilet device is installed in a very low-pressure water pipe where the constant flow valve 28 does not function. Even in such a case, the nozzle body 1 can be protruded while preventing the washing water from being ejected.

  In addition, when the relational expression between the supply flow rate R and the control amount P of the pump 33 is expressed as in Expression (3), the above-described variation means that the function f () varies.

P = f (R) (3)
If the equation (3) is appropriately updated from the relationship between the detected flow rate Q of the flow rate sensor 30 and the control amount P, and the control amount P is determined by the updated function f () and the pump 33 is controlled, the aforementioned variation The nozzle body 1 can be reliably projected in consideration of the above. Here, the update of the expression (3) can be accurately performed when it is performed at the time of local cleaning of the human body in which the cleaning water is supplied at a stable flow rate for a relatively long time.

  Further, the supply flow rate R and the leakage flow rate S change in time series. In general, the pump flow rate deteriorates in time series, so the supply flow rate R decreases. Conversely, the leakage flow rate S increases due to the deterioration of the sealing performance of the seal packing 3. In consideration of the expression (1), the protrusion time T0 becomes longer as the use period elapses. That is, if the protrusion time T0 is determined without taking this time-series change into consideration, the protrusion time T0 may not be sufficient and the nozzle body 1 may not protrude when the usage period is extended. On the other hand, if the protrusion time T0 is set in consideration of changes in time series, that is, if the protrusion time T0 is set longer, the nozzle body 1 is completely set when the use of the toilet device is started. There is a risk that the washing water will erupt vigorously from the ejection holes 5. Therefore, the control unit 40 may be provided with a period measuring unit 42 that measures the usage period of the toilet device, and changes the protrusion time T0 according to the usage period U [days]. If the protrusion time after the change is T, it can be expressed as equation (4).

T [s] = g (U) (However, when U = 0, T = T0) (4)
Note that the function g (U) represents a time-series change in the protrusion time T, and is actually obtained through an endurance test or the like of the toilet device. If the wash water is stopped using the protrusion time T of the equation (4), the nozzle of the wash water can be prevented even if the parts are deteriorated depending on the usage period of the toilet device. The body can protrude.

  Further, the fact that the nozzle body 1 protrudes completely means that the space 9 formed on the rear end side of the nozzle holder 2 is filled with washing water. That is, the position of the nozzle body 1 can be controlled by managing the accumulated amount of cleaning water supplied and accumulated in the space 9. If the supply time t [s] from the start of the supply of cleaning water, the detection flow rate Q [cc / min] of the flow sensor 30 and the leakage flow rate S [cc / min], the accumulated water amount M [cc of the space 9 ] Is as shown in Equation (5).

M [cc] = (Q−S) × t ÷ 60 (5)
As described above, since the leakage flow rate S is determined only by the dimensions of the nozzle and is a fixed value, the accumulated water amount M can be obtained by measuring the supply time t by the control means 4. If the supply of the washing water is stopped before the accumulated water amount M becomes equal to the holder volume H of the space 9, the washing water can be prevented from being ejected even when the performance of the nozzle unit 700 and the pump 33 varies. The nozzle body can protrude.

  In addition, if a nozzle position sensor (not shown) for detecting the front and rear position of the nozzle body 1 is provided and the supply of cleaning water is stopped according to the detected value, even when all the above-described variations occur, The nozzle body can be protruded by reliably preventing the washing water from being ejected.

  Further, when the nozzle body 1 protrudes, the washing water flows out so as to leak from the gap between the outer peripheral surface of the nozzle body 1 and the inner peripheral surface of the opening 2 a of the nozzle holder 2 and the ejection hole 5. When the nozzle body is cleaned, the user holds the nozzle body 1, so it is dangerous if high-temperature washing water leaks. Therefore, if the control means 4 detects an abnormally high temperature with the temperature sensor 32b and stops supplying the cleaning water, safety can be improved.

  In this embodiment, the start of the protrusion operation of the nozzle body 1 is the operation of the cleaning switch 304. However, since cleaning and inspection with the nozzle body 1 protruding is not performed frequently, it is not a dedicated switch operation, but it can be used as a special operation using operation switches of main functions such as washing and drying. There is no decline. Therefore, for example, special operations such as pressing the buttocks switch 303 for 2 seconds are effective in simplifying the operation unit and reducing the cost of the product.

  Further, the main body 200 is provided with a seating sensor (not shown) for detecting the user's seating on the toilet seat 400, and the user is seated for the purpose of preventing the washing water from being ejected due to the user's erroneous operation. There is a toilet device that activates the local washing function of the human body by the buttocks switch 303 and the bidet switch 306 only when the user is in the back. In such a toilet apparatus, when the user is sitting off, if the protrusion operation of the nozzle body 1 is started by operating the butt switch 303, a better feeling of use is obtained. In addition, the operation unit can be simplified and the cost of the product can be reduced.

  In the embodiment of the present invention, the buttocks nozzle 35 and the bidet nozzle 36 correspond to the nozzle device, the pump 33 corresponds to the supply device, the control unit 40 corresponds to the control means, and the nozzle holder 2 corresponds to the cylinder unit. The nozzle body 1 corresponds to the piston portion, the return spring 4 corresponds to the biasing means, the nozzle position sensor (not shown) corresponds to the position detection means, the flow sensor 30 corresponds to the flow detection means, and the temperature The sensor 32b corresponds to the temperature detection means, the remote operation device 300 corresponds to the operation means, the toilet seat 400 corresponds to the toilet seat, and the seating sensor (not shown) corresponds to the seating detection means. Further, the water amount detecting means is constituted by a flow sensor 30 and a time measuring means 41.

  As described above, the toilet apparatus according to the present invention can prevent the washing water from being ejected and can protrude the nozzle body, so that the nozzle body can be easily cleaned and inspected, thereby improving the maintainability. Can be planned.

  In addition, it is easy to pull out the nozzle body even in a configuration in which the nozzle body is retracted deeply into the nozzle holder, the nozzle body is integrally molded to have a seamless structure, or the nozzle surface is smooth processed. In addition, the appearance of the nozzle can be improved, and the design can be improved.
