  In a cleaning device that discharges cleaning water and rinsing water from a nozzle provided in the bathroom washing area, and cleans the floor surface of the washing area, spray the washing water and rinsing water on each part of the entire floor surface and thoroughly wash it. This is very important.

  The nozzle provided toward the washing place is directed obliquely upward, and the washing water and the rinsing water are discharged to a location away from the drainage section of the washing place, and the discharged washing water and the rinsing water are discharged from the upstream portion of the drainage gradient. While it is possible to wash and wash the washing floor when flowing down the slope, it is more efficient if the wash water and rinsing water are poured directly onto each part of the washing floor. In addition, each part of the floor surface of the washing place can be washed and rinsed.

  In the present invention, when the washing water and the rinsing water discharged from the nozzle provided for the washing place flow from the upstream portion of the drainage gradient to the downstream portion of the drainage gradient, the washing water simply rinses by flowing along the surface of the washing floor. In addition, the cleaning water and the rinsing water should be poured directly on each part of the floor of the washing place, so that each part of the floor of the washing place can be cleaned and rinsed more efficiently. Let it be an issue.

  In order to solve the above-mentioned problems, the present invention is a cleaning apparatus that includes a nozzle capable of discharging cleaning water and rinsing water, and in which the cleaning water and rinsing water are discharged onto the floor surface of the washing place, and the discharge direction of the nozzle is obliquely upward The cleaning apparatus is characterized in that the flow rate of the cleaning water and the rinsing water can be increased or decreased.

  It is preferable that the reach of the cleaning water and the rinsing water discharged from the nozzle to the floor of the washing place can be changed.

  It is good also as a structure which arrange | positions a nozzle in the waste-water gradient downstream part of a washing-room floor surface, and reduces the flow volume of washing water and a rinse water gradually.

  It is good also as a structure which arrange | positions a nozzle to the waste-water gradient upstream part of a washing-room floor, and increases the flow volume of washing water and a rinse water gradually.

  According to the cleaning device of the present invention, when the cleaning water and the rinsing water discharged from the nozzle provided toward the washing place flow from the upstream portion of the drainage gradient to the downstream portion of the drainage gradient, the washing floor is not only washed and rinsed. Since the washing water and the rinsing water are poured on each part of the floor of the washing place positively, each part of the washing place can be washed more effectively. Further, when rinsing water is discharged and rinsed on the floor of the washing place, the flow rate of the rinsing water can be changed to facilitate the flow of bubbles, thereby improving the rinsing efficiency.

  The best mode for carrying out the cleaning apparatus of the present invention will be described below with reference to the drawings based on the embodiments. In addition, in order to wash | clean the floor surface of a washing place, a detergent liquid is mixed with warm water and used as washing water, but only warm water may be used as rinse water (rinsing water) without mixing detergent liquid. Hereinafter, in the embodiments, the cleaning water will be described as cleaning water not only in the case of cleaning water in which a detergent solution is mixed with warm water (in a narrow sense), but also in the case of only rinsing water.

  1, 2 and 5 show the configuration of Embodiment 1 of the cleaning apparatus 1 of the present invention. The position of the drainage part 3 is not preferable because the center of the washing place 2 is disturbed by the bather. For example, the position of the drainage part 3 is provided in the washing place 2 in the vicinity immediately below the central part in the longitudinal direction of the apron 4 ′ of the bathtub 4. In the first embodiment, as shown in FIGS. 1A and 2A, the drainage part 3 of the washing place 2 is a substantially central part in the longitudinal direction of the bathtub 4 and is a lower part of the apron 4 ′ of the bathtub 4. It is provided adjacent to.

  Normally, a gentle drainage gradient α (see FIG. 1B) is formed on the entire floor 5 of the washing place toward the drainage section 3. As a result, as shown by the arrow in FIG. 1B and the white arrow in FIG. 2B, the drainage gradient upstream portion of the washing floor 5 is directed to the drainage gradient downstream portion, in short, toward the drainage portion 3. Water flows.

  By the way, the nozzle 6 for cleaning the washing floor 5 (referred to as “washing washing nozzle”) is used to spray the washing water in all directions of the washing floor 5 and pour the washing water over the entire surface. 5 is preferably provided at a position that is as far as possible from the entire surface. In the first embodiment, the cleaning apparatus 1 of the present invention has a configuration in which the washing place cleaning nozzle 6 is provided in the vicinity of the drainage section 3.

  Specifically, as shown in FIGS. 1A, 1 </ b> B, and 2 </ b> A, the bathtub 4 is attached to the lower portion of the elevation portion 7 in the center in the longitudinal direction of the apron 4 ′. As will be described below, the washing place washing nozzle 6 is configured to discharge washing water in all directions of the washing place floor surface 5.

  The washing place washing nozzle 6 is connected to a washing place washing water supply pipe 8 for supplying washing water, and one or a plurality of washing place washing nozzles 6 are provided. In the first embodiment, two washing place washing nozzles 6 are provided. As shown in FIG. 2A, the left area 9 and the right area 10 of the washing floor 5 with the bathtub 4 as the back, respectively. It is installed towards.

  The washing place washing water supply pipe 8 for supplying washing water to the washing place washing nozzle 6 is provided as shown in FIG. 2A and FIG. 5 described later, and is branched in front of the washing place washing nozzle 6, and each of the washing place washing nozzles 6 is provided. It is connected to the.

  The washing place washing nozzle 6 is set so as to be able to discharge in all directions of the washing place floor surface 5 from the arrangement position. Specifically, each of the two washing place cleaning nozzles 6 is a wide nozzle that can discharge cleaning water at a predetermined width in the horizontal direction (the width of the discharge port is larger than the vertical width. It is also referred to as “,” and is attached with the discharge direction set obliquely upward.

  As a result, the two washing place washing nozzles 6 discharge toward all directions of the left area 9 and the right area 10 of the washing floor 5 respectively, and FIG. 1 (a), (b), FIG. 2 (a). As shown in (), the wash water spreads in a fan shape with a gentle parabola and is dissipated.

  When the washing water from the washing place washing nozzle 6 is discharged with such a force as to turn around the lower part of the bathroom wall surface 11 (around the corner between the washing room floor surface 5 and the bathroom wall surface 11), it is shown in FIG. As described above, the washing water flows from the upstream portion of the drainage gradient of the washing floor 5 toward the drainage portion 3 downstream of the drainage gradient, and the washing water is poured over substantially the entire surface of the washing floor 5 and can be washed. It becomes.

  In the cleaning apparatus 1 of the present invention, the momentum of discharge of the cleaning water from the cleaning place cleaning nozzle 6 and the reach distance thereby are adjusted in the cleaning unit 12 that supplies the cleaning water to the cleaning place cleaning nozzle 6. That is, the feature of the present invention is that the flow rate of the cleaning water discharged from the cleaning station cleaning nozzle 6 is increased or decreased to change the reach distance of the cleaning water to the cleaning floor 5 so that the cleaning water flows directly. It is the point which changed the site | part of the floor surface 5, and was set as the structure which wash | cleans the whole surface of the washing floor floor 5 as finely and efficiently as possible.

  The increase or decrease of the flow rate of the cleaning water discharged from the washing place cleaning nozzle 6 may be configured to be performed continuously or may be configured to be performed intermittently (intermittently). According to the configuration that is continuously performed, the portion of the wash floor 5 where the washing water directly pours is continuously changed, and according to the configuration that is intermittently performed, the portion of the wash floor 5 where the wash water pours directly is intermittent. Will change.

  By the way, in the present Example 1, as mentioned above, the washing place washing nozzle 6 is arrange | positioned in the position near the drainage part 3, in other words, the drainage gradient downstream part of the washing place floor surface 5. FIG. Then, as shown in FIG. 1 (b), the washing water from the washing place washing nozzle 6 is discharged toward the upstream portion of the drainage gradient of the washing place floor 5, and the farthest is near the lower part of the bathroom wall surface 11 ( It is discharged with such a force as to pour onto the corners of the wash floor 5 and the bathroom wall 11.

  And the discharge state which pours into the vicinity of the lower part of the bathroom wall surface 11 farthest away, that is, as shown in FIGS. 1B and 2A, the flow rate for discharging the wash water from the maximum state. It was set as the structure which decreases gradually. With such a configuration, the part of the washing floor 5 where the washing water discharged from the washing place washing nozzle 6 pours directly is from the upstream of the drainage gradient near the lower part of the bathroom wall surface 11 to the downstream of the drainage gradient near the drainage part. Gradually, the different parts of the washing floor 5 can be cleaned finely.

  Moreover, the wash water flowing from the upstream part of the drainage gradient and the wash water that pours down while gradually moving to the lower part are merged, and it becomes as if the amount of water flowing from the upstream to the downstream increases in the river, and the wash floor The surface 5 can be sufficiently cleaned.

  Contrary to the above, when the discharge flow rate from the washing station washing nozzle 6 is gradually increased, the portion of the washing floor 5 where the washing water discharged from the washing place washing nozzle 6 is poured directly from the downstream part of the washing place gradient. Gradually move toward the upper part of the gradient.

  In this case, compared with the above case, the washing water from the upstream part of the washing field gradient is less likely to merge and the amount of water increases, and the water flows down from the downstream part of the washing field gradient toward the upstream part of the washing field gradient. Since the washing water flows in the downstream part of the washing field gradient in a state of relatively only the flow rate, the washing effect is not high.

  In short, in the configuration in which the washing place washing nozzle 6 is attached to the downstream part of the washing place gradient, the flow rate at which the washing water is discharged from the washing place washing nozzle is reduced when the flow rate at which the washing water is discharged from the washing place washing nozzle 6 is gradually reduced. Compared to a gradually increasing configuration, even though the total amount of wash water discharged is the same, the wash water from the upstream part of the washing station gradient and the wash water downstream from it flow together, enabling more effective washing. It becomes.

  Furthermore, when rinsing water is discharged and rinsed on the floor of the washing place, the washing place floor is changed by gradually changing the flow of rinsing water from the state of being discharged toward the upstream part of the washing place gradient. By changing the flow of the rinse water on the surface, it is possible to easily flow the bubbles, thereby improving the efficiency of rinsing.

  In the first embodiment, the washing place washing nozzle 6 is provided at the downstream side of the washing place gradient. As an example, the washing place washing nozzle 6 is directed toward the left area 9 and the right area 10 of the washing floor 5. However, such a configuration is not necessarily required.

  That is, if the area of the washing floor 5 is small, or if a nozzle having a structure that can evenly discharge washing water in all directions of the washing floor 5 is used, the number of washing washing nozzles 6 is two. It may be one. Moreover, when the area of the washing floor 5 is large, 3 or more may be sufficient. Further, although there is one washing place washing nozzle 6, it may be configured to have a plurality of discharge ports.

  As described above, the present invention is configured such that the momentum of discharge can be controlled by adjusting the discharge flow rate of the cleaning water discharged from the washing place cleaning nozzle 6. In this way, the operation of supplying the cleaning water discharged from the washing place washing nozzle 6 while adjusting the discharge flow rate is performed in the washing unit 12 for supplying the washing water to the washing place washing nozzle 6 described below.

  FIG. 5 is a block diagram illustrating the overall configuration of a piping system for supplying cleaning water to the washing place cleaning nozzle 6 in the cleaning apparatus 1 according to the present invention. In this cleaning apparatus 1, as shown in FIG. 5, a washing place washing nozzle 6, a bathtub washing nozzle 22 attached to the bathtub 4, a washing unit 12 that supplies washing water to the washing place washing nozzle 6 and the bathtub washing nozzle 22, A detergent tank 23 that is a detergent supply unit that supplies detergent to the cleaning unit 12 and a water heater 24 (hot water supply unit) that supplies hot water to the cleaning unit 12 are provided.

  The water heater 24 is a device that heats water and supplies it as hot water. Usually, a water heater that supplies hot water to the bathtub 4, the faucet 25, and the kitchen is used. The hot water supply 24 is supplied with tap water from a water pipe 26, and is also supplied with hot water from the bathtub 4 through a reheating pipe 27, and is heated to supply hot water to the bathtub 4 from the hot water supply pipe 28 for bathtub. Is done. The water heater 24 is controlled by operations of the bathroom remote controller 30, the kitchen remote controller 31, and the like.

  Hot water is supplied from the water heater 24 to the cleaning unit 12 and the faucet 25 through the hot water supply pipe 32. The bathtub washing nozzle 22 and the washing place washing nozzle 6 are sequentially connected to the three-way valve 34, the washing water supply pipe 35, and the venturi 36 of the washing unit 12 through the bathtub washing water supply pipe 33 and the washing place washing water supply pipe 8. . The cleaning unit 12 is provided with the following devices as a unit in a case.

  The washing unit 12 has a water passage portion 37, and a filter 38, a water amount servo valve 39, a flow rate sensor 40, a pouring electromagnetic valve 41, a check valve 42, two edge cuts are sequentially provided in the water passage portion 37. A valve 43, a check valve 44 and a venturi 36 are arranged. Further, the cleaning unit 12 includes a detergent electromagnetic valve 45 communicating with the venturi 36.

  Each device provided in the water passage portion 37 is connected to the control device 46 and is controlled by the control device 46. The water amount servo valve 39 adjusts the flow rate of the hot water in response to a flow rate adjustment signal from the control device 46 as a flow rate adjusting means. The control device 46 is operated by the cleaning remote controller 29 and controls the opening and closing of the three-way valve 34 to switch and supply the cleaning water to the bathtub cleaning nozzle 22 or the washing place cleaning nozzle 6.

  When a cleaning start signal from the control device 46 is sent to the pouring electromagnetic valve 41, the pouring electromagnetic valve 41 is opened, and hot water is sent from the water heater 24 through the hot water supply pipe 32 into the washing unit 12. The filter 38 of the cleaning unit 12 receives and filters the hot water discharged from the water heater 24, and the flow rate sensor 40 measures the instantaneous flow rate (flow rate / time) of the hot water and transmits a measurement signal to the control device 46. .

  The control device 46 transmits the measured value to the water amount servo valve 39, and the water amount servo valve 39 appropriately controls the degree of opening and closing of the valve according to the measured value, and the flow rate suitable for the washing place washing nozzle 6 to inject. Control to be The two check valves 42 and 44 prevent the backflow of the washing water, and the edge cut-off valve 43 discharges the washing water stopped by the check valve 44 to the outside of the washing unit 12 from the water passage portion 37 when negative pressure is generated. .

  The detergent tank 23 is a tank in which the detergent liquid is filled. The state of filling of the detergent liquid is detected by the float switch 47. When the filling amount is reduced, the detection signal is transmitted to the control device 46, and the control device 46 It is configured to generate a detergent out signal.

  Specifically, a microcomputer (microcomputer) is used for the control device 46, and this microcomputer is configured to be operated by the cleaning remote controller 29. A cleaning operation program is stored in the storage unit of the control device 46, and the water amount servo valve 39 is controlled by the cleaning operation program so that the cleaning water discharge flow rate from the washing place cleaning nozzle 6 is gradually decreased. And an operation of controlling the water amount servo valve 39 so as to gradually increase the cleaning water discharge flow rate.

  Any one of these operations can be selected and set in advance by the operation of the cleaning remote controller 29. In the first embodiment, the water amount servo is controlled so as to gradually decrease the flow rate of the cleaning water discharged from the cleaning station cleaning nozzle 6 in advance. The operation to control the valve is set. Accordingly, when the cleaning operation is started by operating the cleaning remote controller 29, the control device 46 controls the water amount servo valve 39 based on the cleaning operation program, and gradually decreases the discharge flow rate of the cleaning water from the cleaning place cleaning nozzle 6. To do.

(Function)
The operation of the cleaning apparatus 1 having the above configuration is as follows. When the cleaning remote controller 29 is operated to clean the washing floor 5, in FIG. 5, the control device 46 switches the three-way valve 34 to the washing water supply pipe 8 side. Then, the control device 46 opens the pouring electromagnetic valve 41 and controls the water volume servo valve 39 so that the discharge flow rate of the cleaning water discharged from the washing station cleaning nozzle 6 is initially near the lower part of the bathroom wall surface 11. After that, the cleaning water is supplied to the washing station cleaning nozzle 6 while automatically adjusting so as to gradually decrease.

  If the detergent solenoid valve 45 is controlled to open while the pouring solenoid valve 41 is open, the detergent liquid is supplied to the venturi through the detergent supply pipe 48. The detergent solution supplied to the venturi 36 is mixed in hot water that passes through the venturi 36. As a result, cleaning water containing a detergent is prepared and supplied to the washing place washing nozzle 6 and discharged from the washing place washing nozzle 6.

  As shown in FIGS. 1A, 1B, and 2A, the washing water discharged from the two washing place washing nozzles 6 has a fan toward the lower part of the bathroom wall surface 11 in the left and right areas of the bathroom. After pouring into the shape, the discharge rate of the wash water gradually decreases, and the portion of the washing floor 5 where the wash water pours moves from the drain gradient upstream to the drain gradient downstream.

  For this reason, since the wash water flows directly from the upstream part of the drainage gradient to each part of the floor of the washroom downstream of the drainage gradient, compared with the case of washing by simply flowing along the surface of the floor, It is possible to effectively clean substantially the entire floor surface.

  In addition, the wash water that has flowed down the upstream of the drainage gradient and the washwater that has flowed down to the downstream of the drainage gradient merge to increase the amount of water. 5. Clean the entire surface of 5 effectively. Then, the washing water is discharged from the drainage unit 3.

  FIG. 3 is a diagram showing Example 2 of the cleaning device 14 of the present invention. The second embodiment has substantially the same configuration as that of the first embodiment, but the arrangement of the washing place washing nozzles and the control of the discharge flow rate of the washing water are different. The second embodiment will be described below focusing on a configuration different from the first embodiment.

  In the second embodiment, the two washing place washing nozzles 13 are respectively provided in the upstream part of the washing place gradient. Specifically, the washroom washing water supply pipe 8 is branched and connected to the two washroom washing nozzles 13 respectively, and the two washing place washing nozzles 13 are respectively connected to both ends of the bathroom wall 11 facing the bathtub 4 (the bathtub 4 At the opposite corner of washing station 2). Then, the two washing place washing nozzles 13 are respectively washed from the upstream part of the washing place gradient toward the downstream part of the washing place gradient, with the line connecting the washing place washing nozzle 13 and the drainage part 3 approximately as shown in FIG. It was set as the structure which discharges water in fan shape.

  And in the washing | cleaning apparatus 14 of Example 2, although the whole structure of the piping system for supplying washing water to the two washing place washing | cleaning nozzles 13 is substantially the same as the block diagram of Example 1 shown in FIG. Is omitted, but the washing-cleaning water supply pipe is branched and connected to two washing-cleaning nozzles. The characteristic configuration of the second embodiment is that the operation of gradually increasing the discharge flow rate of the washing water from the washing place washing nozzle included in the washing program of the control device 1 described in the first embodiment is operated in advance by operating the washing remote controller. The configuration is selected and set.

  In short, in the cleaning device 14 of the second embodiment, the two washing place washing nozzles 13 are respectively provided in the upstream part of the washing place gradient, and as shown in FIGS. The discharge flow rate of cleaning water from is gradually increased. As described above, when the discharge rate of the wash water is gradually increased, the portion of the wash floor 5 where the wash water discharged from the wash-cleaning nozzle 13 pours down continuously is continuous from the upstream portion of the wash place gradient toward the downstream portion of the wash place gradient. Gradually move.

  Thus, as in the first embodiment, the wash water flows directly from the upstream portion of the drainage gradient to each part of the washing floor 5 of the downstream portion of the drainage gradient. The substantially whole surface of the washing floor 5 can be effectively cleaned. In addition, as it goes toward the downstream part of the drainage gradient, the wash water from the upstream part of the drainage gradient and the upstream part of the drainage gradient merge to increase the amount of water, thereby improving the cleaning effect of the washing floor 5.

  Contrary to the above, when the discharge flow rate from the washing place washing nozzle 13 is gradually reduced, the part of the washing place floor 5 where the washing water pours gradually moves from the washing place gradient downstream part toward the washing place gradient upstream part. In this case, compared with the above case, as the water flows from the washing section gradient upstream part to the downstream part of the washing field gradient, it is less likely that the amount of water increases and the amount of water increases. Since each of them flows to the downstream part of the washing field gradient in the state of the flow rate of only the washing water that has flowed down to each part, the cleaning effect is not high.

  In short, if the discharge flow rate of the washing water from the washing place washing nozzle 13 is gradually increased, the discharge amount of the washing water is smaller than that in the case where the discharge flow rate of the washing water from the washing place washing nozzle 13 is gradually reduced. Even if the total amount of flow to be performed is the same, it flows together with the washing water from the upstream part of the washing field gradient, so that washing can be performed more effectively.

  Further, when rinsing water is discharged and rinsed on the floor of the washing place, the washing place floor is changed by gradually changing the flow rate of the rinsing water from the state of being discharged to the downstream part of the washing place gradient. By giving fluctuations to the flow of flowing rinse water, it is possible to facilitate the flow of bubbles, thereby improving the efficiency of rinsing.

(Modification)
FIG. 4 is a diagram showing a modification of the second embodiment of the present invention. The cleaning device 15 of this modified example has substantially the same configuration as that of the second embodiment, but as shown in FIG. 4A, the washing place washing water supply pipe 8 is branched and each of the two washing place washing nozzles 16 is provided. The two washing place washing nozzles 16 are connected to each other at both ends in the longitudinal direction of the apron 4 ′ of the bathtub 4.

  In short, the two washing place washing nozzles 16 are respectively arranged at the substantially corner portions of the washing place 2, which are also upstream of the drainage gradient. And as shown to Fig.4 (a), the two washing place washing | cleaning nozzles 16 were set as the structure which discharges washing water in fan shape centering | focusing on the line which connects the washing | cleaning place washing nozzle 16 and the center part 2C of the washing place 2, respectively. . Also in this modified example, the discharge flow rate of the washing water from the washing place washing nozzle 16 is gradually increased as in the second embodiment.

  In this modification, on the washing floor 5 on the line connecting the washing area washing nozzle 16 and the drainage section 3, as shown in FIG. 4 (b), the slope gently descends from the washing area washing nozzle 16 toward the drainage section 3. A surface is formed, and the washing water discharged from the washing place washing nozzle 16 is configured to go from the washing place gradient upstream part to the washing place gradient downstream part. However, as compared with the second embodiment, the cleaning water discharged from the washing place washing nozzle 16 is not all configured to go from the washing place gradient upstream portion toward the washing place gradient downstream portion.

  Rather, the washing water from the washing place washing nozzle 16 is generally discharged from the side of the washing place gradient upstream side. However, as shown in FIG. 4 (b), the washing floor 5 on the line connecting the washing area washing nozzle 15 and the drainage section 3 includes a configuration from the washing area gradient upstream to the washing area gradient downstream. In addition, an example of a configuration in which the upstream of the washing field gradient is directed to the downstream of the washing field gradient.

  The best mode for carrying out the cleaning apparatus according to the present invention has been described based on the embodiments. However, the present invention is not limited to such embodiments, and is described in the claims. It goes without saying that there are various embodiments within the scope of technical matters.
