A unit 3, a detergent supply tank 4 that is a detergent supply unit that supplies detergent to the functional unit 3, and a hot water supply unit 5 that supplies hot water to the functional unit 3 are provided.

  The hot water supply unit 5 is a device that heats water and supplies it as hot water, and a water heater that supplies hot water to the bathtub 1, the faucet 6, the kitchen, or the like is usually used. The hot water supply unit 5 is supplied with tap water from the water pipe 7 and is also supplied with hot water from the bathtub 1 through the reheating pipe 8 and is heated to supply hot water to the bathtub 1 from the bathtub supply pipe 9. Is done. The hot water supply unit 5 is controlled by operations of the cleaning remote controller 10, the bathroom remote controller 11, the kitchen remote controller 12, and the like.

  Hot water is supplied from the hot water supply unit 5 to the functional unit 3 and the faucet 6 through the hot water supply pipe 5 ′. The cleaning nozzle 2 is a nozzle that injects cleaning water toward the inner surface of the bathtub 1, and is connected to the venturi 14 of the functional unit 3 through the cleaning water supply pipe 13.

  The functional unit 3 includes a case 15, and the case 15 is watertightly sealed with a lid 16 (see FIG. 1) via a packing. FIG. 3 is a front view showing an internal configuration of the case 15 of the functional unit 3. The functional unit 3 will be described with reference to FIGS.

  As shown in FIGS. 2 and 3, the functional unit 3 has a water passage portion 17, and a filter 18, a water amount servo valve 19, a flow rate sensor 20, and a pouring electromagnetic valve are sequentially provided in the water passage portion 17. 21, a check valve 22, two edge cut valves 23 and 23, a check valve 24 and a venturi 14 are arranged. Further, the functional unit 3 includes a detergent electromagnetic valve 25 that communicates with the venturi 14.

  Each device provided in the water passage portion 17 is controlled by the control device 26. When a cleaning start signal from the control device 26 is sent to the pouring solenoid valve 21, the pouring solenoid valve 21 is opened, and hot water is sent from the hot water supply section 5 to the functional unit 3 through the hot water supply pipe 5 '. The filter 18 of the functional unit 3 receives and filters the hot water discharged from the hot water supply unit 5, and the flow rate sensor 20 measures the instantaneous flow rate (flow rate / time) of the hot water and transmits a measurement signal to the control device 26. To do.

  The control device 26 transmits the measured value to the water volume servo valve 19, and the water volume servo valve 19 appropriately controls the degree of opening and closing of the valve according to the measured value, and the flow rate is suitable for the cleaning nozzle 2 to inject. Control every moment. The two check valves 22 and 24 prevent the backflow of the wash water, and the edge cut valves 23 and 23 drain the wash water stopped by the check valves 22 and 24 from the water passage portion 17 to the outside of the functional unit 3. It discharges through 23 'and 23'.

  The detergent supply tank 4 is a tank in which the detergent liquid is put. The state of the detergent liquid filling is detected by the float switch 27. When the filling amount decreases, the detection signal is transmitted to the control device 26, and the control device 26 Is configured to generate a detergent out signal.

  The control device 26 is operated by the cleaning remote controller 10. In response to this operation, the hot water electromagnetic valve 21 opens for cleaning the bathtub 1, and supplies a certain amount of hot water as cleaning water to the cleaning nozzle 2. The control device 26 controls the detergent solenoid valve 25 to open while the pouring solenoid valve 21 is open, and supplies the detergent liquid to the venturi 14 through the detergent supply pipe 45. The detergent solution supplied to the venturi 14 is mixed in hot water passing through the venturi 14. Accordingly, cleaning water containing detergent is prepared and supplied to the cleaning nozzle 2.

  Although the whole structure of the bathroom of this invention is as above, the characteristic structure of the bathroom of this invention is further demonstrated below.

  As shown in FIG. 4, the functional unit 3 is installed below the bathtub flange 28 and near the washing place 29, so that the functional unit 3 is influenced by high humidity in the bathroom. Therefore, as shown in FIGS. 1 and 3 to 5, a communication hose 30 is provided for communicating the air layer in the functional unit 3 with the outside of the bathroom. The “air layer” in the functional unit 3 is a space 15 ′ in the case 15 (a simple space in the case 15 in which equipment such as the water amount servo valve 19 excluding the filter 18 in the water passage portion 17 is accommodated). It is not a special meaning such as providing an air tank.

  As shown in FIGS. 3, 5 (a) and 5 (b), one end of the communication hose 30 is fitted into a mounting plug 32 that is attached through the side wall 31 of the case 15 of the functional unit 3, The other end extends outside the bathroom through a through hole 44 (see FIG. 1) for an electrical cable formed in the bathroom wall. The opening on the case 15 side of the mounting plug 32 communicates with the air layer in the case 15. In short, it faces the space 15 ′ in the case 15.

  As shown in FIG. 5, a water leakage prevention valve 33 is mounted in the communication hose 30. This mounting position is in the vicinity of the functional unit 3 at the connection portion where the communication hose 30 is connected to the functional unit 3, and specifically, adjacent to the opening of the mounting plug 32 on the side opposite to the case 15. By being mounted at this position, there is an effect that it is easy to check whether the water leakage prevention valve is attached or not attached in the reverse direction when connecting the communication hose to the functional unit.

  5C and 5D show the structure of the water leakage prevention valve 33. FIG. The water leakage prevention valve 33 includes a water leakage prevention valve main body 34 formed of a cylindrical body, a flange cylinder 36 press-fitted, screwed or fitted into one end opening 35 of the water leakage prevention valve main body 34, and a check valve ball 37. ing.

  The water leakage prevention valve body 34 is formed with a tapered surface 40 whose diameter decreases from the cylindrical hole 38 toward the other end opening 39. A check valve ball 37 is inserted into the cylindrical hole 38. The check valve ball 37 has a weight enough to be moved by being pushed by the water flow. The flange cylinder 36 has a cylinder portion 41 that fits into the water leakage prevention valve main body 34, and a notch hole 43 that communicates with the through hole 42 of the flange cylinder 36 is formed at the inner end of the cylinder portion 41.

  One end side (flange cylinder 36 side) of the water leakage prevention valve 33 is directed to the mounting plug 32 side of the functional unit 3, and the other end opening 39 side is directed to the direction outside the bathroom in the communication hose 30. As shown in FIG. 5 (e), the air from outside the bathroom that flows into the cylindrical hole 38 from the other end opening 39 through the communication hose 30 passes through the gap between the check valve ball 37 and the cylindrical hole 38, and the cutout hole 43 Then, it passes through the through hole 42 of the flange cylinder 36 and the mounting plug 32 and flows into the space 15 ′ in the case 15 of the functional unit 3. In this case, even if the check valve ball 37 is pushed and moved in the left direction in the drawing as shown in FIG. 5E by the flow of air, the air flows from the notch hole 43 and is sealed. There is nothing.

  On the contrary, the moisture in the functional unit 3 passes through the other end opening 39 from the through hole 42 of the water leakage prevention valve 33 and is naturally discharged outside the bathroom. In other words, the water leakage prevention valve 33 is not sealed to such an extent that moisture that does not move the check valve ball 37 is naturally exhausted. However, the water flowing into the cylindrical hole 38 from the flange cylinder 36 side of the water leakage prevention valve 33 is moved by pushing the check valve ball 37 in the right direction in FIG. Since the other end opening 39 is sealed so as to fit into 40, it does not flow out to the bathroom side through the communication hose 30.

  Further, the mounting plug 32 protrudes from the functional unit 3 in the horizontal direction, and since the communication hose is maintained in the horizontal direction at a position near the connection portion to which the communication hose is connected, the water leakage prevention valve 33 is maintained in the horizontal direction. Has been attached. Therefore, the check valve ball 37 of the water leakage prevention valve 33 can operate without being affected by gravity.

(Function)
The operation of the bathroom of the present invention having the above configuration will be described below with a focus on the bathtub cleaning device. At the time of cleaning the bathtub 1, when the pouring electromagnetic valve 21 is opened by the control device 26 operated by the cleaning remote controller 10, the cleaning nozzle 2 supplies hot water as cleaning water from the hot water supply section 5 through the water passage section 17 of the functional unit 3. To supply.

  In the water passage portion 17 of the functional unit 3, an instantaneous supply flow rate (supply flow rate / time) of hot water is measured by the flow rate sensor 20, and the control device 26 controls the opening / closing of the water amount servo valve 19 based on the measured value. The supply flow rate is adjusted every moment, and the detergent solution is mixed with the venturi 14 and sent to the washing nozzle 2 through the washing water supply pipe 13 as washing water containing the detergent.

  Normally, the water leakage prevention valve 33 is not closed, and air is circulated through the communication hose 30 between the space 15 ′ in the functional unit 3 and the outside of the bathroom. Therefore, the inside of the bathroom has high humidity, but the humidity in the functional unit 3 is naturally excluded outside the bathroom, or air with relatively low humidity outside the bathroom flows into the functional unit 3, and the inside of the functional unit 3. Is kept at almost the same humidity as outside the bathroom and does not become as high as in the bathroom.

  By the way, when water leaks from the water passage portion 17 of the functional unit 3 for some reason and water accumulates in the space 15 ′ in the functional unit 3, it tries to leak out of the bathroom through the communication hose 30. However, even in such a case, the check valve ball 37 closes the other end opening 39 in the water leakage prevention valve 33 to stop the water, thereby preventing the water in the functional unit 3 from leaking out of the bathroom. it can. As a result, it is possible to prevent a secondary disaster such as flooding outside the bathroom.

  The water leakage is prevented by the water leakage prevention valve 33 and the functional unit 3 is filled with water leakage. However, when the water pressure in the functional unit 3 increases, the water pressure causes the gap between the case 15 and the lid 16 to be opened. Since it flows out of the functional unit 3, problems such as breakage of the functional unit 3 do not occur.

  As mentioned above, although the best form for implementing the bathroom concerning this invention was demonstrated based on the Example, this invention is not limited to such an Example, The technique described in the claim It goes without saying that there are various embodiments within the scope of the subject matter.
