Description

Bathroom cleaning system and faucet unit

[0001] The present disclosure relates to a bathroom cleaning system and a faucet unit.

[0002] Patent document 1 describes a bathroom cleaning device that has a water discharge section that can discharge water toward the floor of the washing area, located below a counter that is positioned below the faucet body to which a shower hose is connected.

[0003] The water discharge section is provided on the underside of the counter or on the bathroom wall below the counter, and is configured so that water can also be discharged toward the underside of the counter.

[0004] The water discharge section is connected to a water pipe, hot water supply means, or sterilizing water supply means via a water discharge control means installed outside the bathroom, and dirt in the washing area can be cleaned by discharging tap water, hot water, or sterilizing water (hereinafter referred to as ``tap water, etc.'').

[0005] In recent years, there has been an increasing demand for bathrooms that do not have low-level counters, in order to reduce the burden of maintenance.

[0006] The bathroom cleaning device described in Patent Document 1 has a water outlet on the underside of the counter and sprays tap water or the like from the water outlet toward the underside of the counter, making it difficult to apply to bathrooms that do not have a counter.

[0007] Furthermore, with this bathroom cleaning device, the faucet body and the water discharge unit are positioned far apart in the vertical direction across the counter, which poses the problem of requiring a large amount of vertical space for the faucet body and the water discharge unit.

[0013] (Embodiment 1) 1. Overview The bathroom cleaning system of embodiment 1 shown in Figure 1 comprises a faucet unit 7 having a faucet body 3 to which at least one of a shower hose 1 and a water outlet 2 is connected, and a cleaning nozzle 6 connected to the faucet body 3 and spraying water toward at least one of a bathtub 4 and a washing area 5. The bathroom cleaning system further comprises a cover 8 that covers the faucet unit 7, and a control unit 10 that controls the spraying of water from the cleaning nozzle 6.

[0014] In addition, the faucet unit 7 of embodiment 1 comprises a faucet body 3 to which at least one of the shower hose 1 and the water outlet 2 is connected, and a cleaning nozzle 6 connected to the faucet body 3 and spraying water toward at least one of the bathtub 4 and the washing area 5.

[0015] In the bathroom cleaning system and faucet unit 7 of embodiment 1 having the above configuration, the cleaning nozzle 6 can be positioned close to the faucet body 3, thereby reducing the amount of space required for the faucet body 3 and the cleaning nozzle 6. Furthermore, because the cleaning nozzle 6 is connected to the faucet body 3, this bathroom cleaning system and faucet unit can be used in bathrooms that do not have a low-positioned counter. Therefore, this bathroom cleaning system and faucet unit can be used in bathrooms that do not have a low-positioned counter, and can also reduce the amount of space required for installation.

[0016] 2. Details Next, the bathroom cleaning system and faucet unit 7 of embodiment 1 will be described in more detail with reference to the drawings. As shown in Figure 1, the bathroom cleaning system and faucet unit 7 are applied to a bathroom 9 that is installed at a low position and does not include a counter.

[0017] Here, the counter installed at a low position refers to a counter installed below the faucet body 3 on which bathroom products such as shampoo or a washbasin are placed. The height of this counter is set so that a user sitting on a chair placed in the washing area 5 can easily reach the bathroom products or washbasin placed on the counter, and is, for example, about 450 mm high. The bathroom 9 has a bathtub 4 and a washing area 5. Below, the direction in which the bathtub 4 and the washing area 5 are lined up is defined as the left-right direction, and the longitudinal direction of the bathtub 4 is defined as the front-rear direction, and each configuration will be explained using the front-rear, left-right, up-down directions shown in Figure 1.

[0018] The bathroom cleaning system comprises a faucet unit 7 having a faucet body 3 to which at least one of a shower hose 1 and a water outlet 2 is connected, and a cleaning nozzle 6 connected to the faucet body 3 and spraying water toward at least one of a bathtub 4 and a washing area 5. The bathroom cleaning system further comprises a cover 8 that covers the faucet unit 7, and a control unit 10 that controls the spraying of water from the cleaning nozzle 6.

[0019] The bathroom cleaning system further includes an operating unit 11 located outside the bathroom 9 and operable by the user, an opening / closing detection unit 12 that detects the opening / closing state of the door 93 that opens and closes the entrance / exit 92 of the bathroom 9, and a notification device 13 that notifies the operating status of the control unit 10.

[0020] The faucet unit 7 further includes a water supply pipe 14 connecting the faucet body 3 and the cleaning nozzle 6, and a control valve 15 provided midway along the water supply pipe 14.

[0021] The bathroom 9 comprises a bathtub 4, a floor pan 50 constituting the washing area 5 adjacent to the bathtub 4, a bathroom side wall 90 rising upward from the outer periphery of the bathtub 4 and the washing area 5 excluding the boundary between the bathtub 4 and the washing area 5, and a ceiling section 91. The ceiling section 91 is composed of two ceiling panels aligned in the left-right direction.

[0022] The bathroom side wall 90 is composed of multiple wall panels, specifically four wall panels. The four wall panels include a pair of wall panels 90a facing each other in the left-right direction (i.e., the direction in which the bathtub 4 and the washing area 5 are aligned) and a pair of wall panels 90b facing each other in the front-rear direction. Note that the front wall panel 90b is not shown in Figure 1.

[0023] Of the pair of wall panels 90a, the wall panel 90a adjacent to the washing area 5 (i.e., the right side) has a door 93 in the front portion thereof for opening and closing the door 92. The door 93 is, for example, a bifold door. The faucet body 3 is attached to the rear wall panel 90b.

[0024] The bathtub 4 has a concave bathtub body 40 in which hot water can be stored, a flange 41 protruding from the periphery of the upper opening of the bathtub body 40, and an apron 42 extending downward from one end (specifically the right end) of the flange 41. The apron 42 is adjacent to the floor pan 50 that constitutes the washing area 5, and stands on the outer edge of the left side of the floor pan 50.

[0025] In this embodiment, the bathroom 9 includes both a shower hose 1 connected to a faucet body 3 and a water outlet 2 connected to the faucet body 3. A shower head is attached to the end of the shower hose 1. The water outlet 2 opens downward.

[0026] The faucet body 3 is connected to a water pipe 100 and a hot water supply device 101 outside the bathroom 9 via control valves 102, 103. Cold water and hot water are supplied to the faucet body 3 from the water pipe 100 and the hot water supply device 101.

[0027] The faucet body 3 is provided with a plurality of buttons that are operated by the user. The plurality of buttons include a temperature adjustment button 30, a flow rate adjustment button 31, a water discharge button 32, and a shower button 33.

[0028] The temperature adjustment button 30 is a button for adjusting the temperature of hot water supplied to one of the shower hose 1, the spout 2, and the washing nozzle 6. When the user operates the temperature adjustment button 30, the opening degree of the control valves 102, 103 is changed, and hot water at the selected temperature is supplied to the faucet body 3.

[0029] The flow rate adjustment button 31 is a button for adjusting the flow rate of hot and cold water supplied to the shower hose 1 or the spout 2. The water discharge button 32 is a button for discharging water from the spout 2. When the user operates the water discharge button 32, an on-off valve 104 provided in the flow path connecting the faucet body 3 and the spout 2 opens and closes, thereby switching whether or not water is discharged from the spout 2.

[0030] The shower button 33 is a button for discharging water from the shower head of the shower hose 1. When the user operates the shower button 33, an on-off valve 105 provided in the flow path connecting the faucet body 3 and the shower hose 1 opens and closes, thereby switching whether or not water is discharged from the shower head.

[0031] The faucet body 3 is covered with a cover 8 , and more specifically, the entire faucet body 3 except for the plurality of buttons 30 to 33 is covered with the cover 8 .

[0032] In this embodiment, the cover 8 is a rectangular box-like structure extending in one direction (specifically, the left-right direction). The cover 8 has an upper surface 810 on which bathroom products such as soap, shampoo, conditioner, and body wash can be placed. The front-to-rear length of the upper surface 810 is set to a length that allows the placement of the above-mentioned bathroom products, for example, 100 mm to 200 mm. Note that the upper surface 810 is not long enough to allow the placement of a washbasin, and is shorter in the front-to-rear direction than conventional bathroom counters that are installed at a low position.

[0033] The upper surface 810 is a surface parallel to the horizontal plane or a surface that is slightly inclined downward toward the center (i.e., the front) of the washing area 5 for drainage. The upper surface 810 may be flat or may have an uneven surface. The upper surface 810 is configured so that bathroom items placed on it do not slide off.

[0034] The cover 8 comprises a front wall 80 that covers the faucet body 3 from the front, an upper wall 81 that covers the faucet body 3 from above, a pair of left and right side walls 82, 83 that cover the faucet body 3 from the left and right, and a lower wall 84 that covers the faucet body 3 from below. The cover 8 may further comprise a rear wall that fits along the rear wall panel 90b. Note that the cover 8 does not necessarily have to have the left and right side walls 82, 83, or the lower wall 84.

[0035] The front wall portion 80 is provided with a plurality of insertion holes 800 through which the plurality of buttons 30, 31, 32, 33 of the faucet body 3 are inserted. As a result, the remaining portion of the faucet body 3, excluding the plurality of buttons 30, 31, 32, 33, is covered and hidden from the front by the front wall portion 80.

[0036] In this embodiment, the cover 8 is located above the washing area 5, but not above the bathtub 4. The left-right length of the cover 8 is shorter than the left-right length of the washing area 5. The cover 8 is attached to the upper part of the rear wall panel 90b above the washing area 5 (i.e., the right half). Note that the cover 8 may be attached to the faucet body 3, thereby being indirectly attached to the rear wall panel 90b.

[0037] The height H1 of the top surface 810 of the cover 8 from the floor of the washing area 5 (i.e., the top surface of the floor pan 50) is 450 mm or more and 950 mm or less. In this embodiment, the height H1 is 680 mm. The vertical length of the cover 8 is, for example, approximately 110 mm. The height H2 of the top surface of the flange 41 of the bathtub 4 from the floor of the washing area 5 is 450 mm. For example, if the bathroom 9 is a type that the user uses while standing, it is preferable to set the height H1 in a range close to 950 mm, but the height H1 is not limited to this.

[0038] The operating unit 11 is installed on the outer wall of the bathroom 9, adjacent to the entrance / exit 92. In this embodiment, the operating unit 11 incorporates a control unit 10. The operating unit 11 and the control unit 10 are electrically connected. The control unit 10 is a device whose main component is a computer system such as a microcomputer or a personal computer.

[0039] The operation unit 11 is provided with a plurality of buttons that can be operated by the user, and a display unit (not shown) that displays the operating status of the control unit 10. When the user operates the plurality of buttons on the operation unit 11, a control signal is transmitted from the operation unit 11 to the control unit 10.

[0040] The control unit 10 receives a control signal sent from the operation unit 11 and controls the spraying of water from the cleaning nozzle 6. The control unit 10 is electrically connected to a control valve 15 provided in a water supply pipe 14 connecting the cleaning nozzle 6 and the faucet body 3. In this embodiment, the control valve 15 is a solenoid valve, an electric valve, or the like. The control unit 10 switches between spraying water from the cleaning nozzle 6 and not spraying water by opening and closing the control valve 15. The control valve 15 may be a control valve whose valve opening degree can be adjusted, or may be one that can adjust the amount of water sprayed from the cleaning nozzle 6.

[0041] The open / close detection unit 12 is installed, for example, around the entrance / exit 92 of the bathroom 9. The open / close detection unit 12 is electrically connected to the control unit 10. The open / close detection unit 12 detects the open / close state of a door 93 that opens and closes the entrance / exit 92 of the bathroom 9, and transmits the detection result to the control unit 10. The control unit 10 controls the spraying of water from the cleaning nozzle 6 while the open / close detection unit 12 detects that the door 93 is closed.

[0042] The bathroom cleaning system may further include an obstacle detection unit that detects the presence or absence of obstacles, such as a chair or washbasin, above the washing area 5. In this case, the control unit 10 controls the spraying of water from the cleaning nozzle 6 while the obstacle detection unit detects that there is no obstacle above the washing area 5.

[0043] The notification device 13 is incorporated in, for example, the operation unit 11. The notification device 13 is electrically connected to the control unit 10. The notification device 13 is a speaker and notifies the operating status of the control unit 10 by voice.

[0044] The notification device 13 may, for example, notify the user when the bathroom cleaning has started or finished, or notify the user that the bathroom cleaning cannot be started (specifically, the door 93 is open, there is an obstacle in the washing area 5, etc.), or may do both. The content of the notification by the notification device 13 can be set as appropriate.

[0045] 3. Operation of the Bathroom Cleaning System Next, the operation of the bathroom cleaning system described above will be explained.

[0046] Before starting the bathroom flush, the user operates the temperature adjustment button 30 on the faucet body 3 to set the temperature of the hot water supplied from the faucet body 3 to the flush nozzle 6 to a temperature suitable for bathroom flushing (for example, 42 degrees or higher). The user also moves any obstacles on the floor pan 50 of the washing area 5 onto the bathtub 4 or outside the bathroom 9.

[0047] Next, the user closes the door 93 and operates the operation unit 11 outside the bathroom 9 to press the bathroom cleaning start button. This sends a control signal from the operation unit 11 to the control unit 10, which then controls the control valve 15 to open and spray hot water from the cleaning nozzle 6. At this time, the notification device 13 notifies the user by voice that the bathroom cleaning has started.

[0048] At this time, if the detection results of a detection unit such as the open / close detection unit 12 sent to the control unit 10 indicate that the door 93 is open or that there is an obstacle on the floor pan 50 of the washing area 5, the control unit 10 stops the spray of hot water from the washing nozzle 6. Then, the notification device 13 notifies the user of the above situation by voice, urging the user to close the door 93, move the obstacle, or both.

[0049] The control unit 10 causes the washing nozzle 6 to spray hot water for a predetermined time in accordance with a program stored in the control unit 10. In this embodiment, washing water is sprayed from the washing nozzle 6 onto the upper surface of the floor pan 50 of the washing area 5, and onto the surrounding areas, namely, the lower part of the apron 42 of the bathtub 4 and the lower part of the bathroom side wall 90. Here, the lower parts of the bathroom side wall 90 refer to the lower parts of the right wall panel 90a, the lower part of the door 93, the lower part of the rear wall panel 90a, and the lower part of the front wall panel 90a, which are areas where soap scum and sebum stains tend to accumulate.

[0050] When a predetermined time has elapsed since the start of water spraying from the cleaning nozzle 6, the control unit 10 controls the control valve 15 to close, thereby stopping the water spraying from the cleaning nozzle 6. The notification device 13 then notifies the user that the bathroom cleaning has been completed.

[0051] 4. Effects In the bathroom cleaning system of the present embodiment described above, the cleaning nozzle 6 is connected to the faucet body 3, so the cleaning nozzle 6 can be positioned close to the faucet body 3, thereby reducing the space required for the faucet body 3 and the cleaning nozzle 6.

[0052] In addition, in the bathroom cleaning system of this embodiment, since the cleaning nozzle 6 is connected to the faucet body 3, it can also be applied to bathrooms 9 that are installed at a low position and do not have a counter.

[0053] Therefore, the bathroom cleaning system of this embodiment can be applied to a bathroom 9 that does not require a counter installed at a low position, and the installation space can be reduced.

[0054] In addition, with the bathroom cleaning system of this embodiment, it is possible to omit the counter that is installed at a low position, eliminating the need to clean the underside of this counter and the bathroom side walls and washing area floor below the counter, thereby reducing the burden of maintenance.

[0055] In addition, in the bathroom cleaning system of this embodiment, the faucet body 3, cover 8, cleaning nozzle 6, and water outlet 2 are connected adjacent to each other to form a single unit, so that it can have a simple design while still providing cleaning function for the washing area 5.

[0056] Furthermore, with the bathroom cleaning system of this embodiment, water can be sprayed from cleaning nozzle 6, which is located at a relatively high position, at a height H1 of 450 mm or more from the top surface of floor pan 50 of washing area 5. Therefore, with the bathroom cleaning system of this embodiment, it is easy to clean not only the top surface of floor pan 50 of washing area 5, but also the surrounding area (i.e., apron 42 and the lower part of bathroom side wall 90).

[0057] In addition, in the bathroom cleaning system of this embodiment, the height H1 of the cover 8 from the top surface of the floor pan 50 of the washing area 5 is approximately 680 mm, so that the water sprayed from the cleaning nozzle 6 can easily reach the floor surface of the washing area 5 while maintaining the water temperature, making it easy to remove dirt from the floor surface.

[0058] In addition, in the bathroom cleaning system of this embodiment, the height H1 of the cover 8 from the top surface of the floor pan 50 of the washing area 5 is relatively high at approximately 680 mm, so the cover 8, faucet body 3, spout 2, and cleaning nozzle 6 are less likely to get dirty and are easy to clean.

[0059] In addition, in the bathroom cleaning system of this embodiment, there is no need for a separate dedicated supply means for supplying hot water or the like to the cleaning nozzle 6, so the work of creating a hole in the bathroom side wall to pass the dedicated supply means through and the work of stopping the water flow can be omitted, making it easy to install the cleaning nozzle 6 in the bathroom 9.

[0060] (Embodiment 2) Next, we will explain the bathroom cleaning system and faucet unit 7 of embodiment 2 shown in Figures 3 and 4. In the following, for the bathroom cleaning system and faucet unit 7 of embodiment 2, components similar to those of the bathroom cleaning system and faucet unit 7 of embodiment 1 will be assigned the same reference numerals and detailed explanations will be omitted, and components that differ will be explained in detail.

[0061] In the bathroom cleaning system of embodiment 2, the cleaning nozzle 6 includes a bathtub cleaning nozzle 6a that sprays water toward the bathtub 4 and a washing area cleaning nozzle 6b that sprays water toward the washing area 5. The bathtub cleaning nozzle 6a and the washing area cleaning nozzle 6b are separate nozzles.

[0062] The cover 8 extends from above the bathtub 4 to above the washing area 5. The bathtub cleaning nozzle 6a is located above the bathtub 4, and the washing area cleaning nozzle 6b is located above the washing area 5. The washing area cleaning nozzle 6b is configured to spray water over the same range as the cleaning nozzle 6 of embodiment 1. The bathtub cleaning nozzle 6a is configured to spray water over the concave bathtub body 40 and flange 41 of the bathtub 4.

[0063] The cover 8 has a length that spans the entire length of the rear wall panel 90b in the left-right direction. The top surface 810 of the cover 8 can accommodate bathroom items along its entire length in the left-right direction. The height H1 of the cover 8 from the floor of the washing area 5 (i.e., the top surface of the floor pan 50) is higher than the height H2 of the flange 41 of the bathtub 4 from the floor of the washing area 5, and is, for example, between 650 mm and 950 mm. In this embodiment, the height H1 is 680 mm.

[0064] The bathroom cleaning system further includes a detergent tank 16 for supplying detergent to the hot and cold water supplied from the faucet body 3 to the cleaning nozzle 6. The detergent tank 16 is incorporated into the cover 8. In this embodiment, the detergent tank 16 is connected to the bathtub cleaning nozzle 6a via a supply pipe 17. A pump 18 and a control valve 19 are provided along the supply pipe 17. The control valve 19 is, for example, a solenoid valve or an electric valve. The pump 18 and the control valve 19 are electrically connected to and controlled by the control unit 10. The detergent tank 16, supply pipe 17, pump 18, and control valve 19 are each housed within the cover 8.

[0065] The detergent tank 16 is disposed, for example, inside the portion of the cover 8 above the tub 4. The portion of the cover 8 that covers the detergent tank 16 is provided with an opening for exposing the detergent tank 16 and a lid that is removably attached to the opening. By opening the lid to expose the detergent tank 16, new detergent can be filled into the detergent tank 16. The detergent tank 16 may be provided so that it can be replaced with a new detergent tank 16 filled with detergent.

[0066] The water supply pipe 14 connecting the faucet body 3 and the cleaning nozzle 6 branches into two flow paths along the way, including a first water supply pipe 14a connected to the bathtub cleaning nozzle 6a and a second water supply pipe 14b connected to the washing area cleaning nozzle 6b.

[0067] The first water supply pipe 14a and the second water supply pipe 14b are provided with control valves 15a and 15b, respectively. Each of the control valves 15a and 15b is, for example, a solenoid valve or an electric valve. Each of the control valves 15a and 15b is electrically connected to the control unit 10 and is controlled by the control unit 10.

[0068] The control unit 10 has a bathtub cleaning mode suitable for cleaning the bathtub 4 and a washing area cleaning mode suitable for cleaning the washing area 5. In the bathtub cleaning mode, the control unit 10 controls the bathtub cleaning nozzle 6a to alternately spray hot water containing detergent and hot water not containing detergent, and then finally sprays hot water not containing detergent. In the washing area cleaning mode, the control unit 10 controls the washing area cleaning nozzle 6b to spray hot water not containing detergent.

[0069] Next, the operation of the bathroom cleaning system of the second embodiment will be described.

[0070] Before starting bathroom cleaning, the user operates the temperature adjustment button 30 on the faucet body 3 to set the temperature of the hot water supplied from the faucet body 3 to the cleaning nozzles 6 (specifically, the bathtub cleaning nozzle 6a and the washing area cleaning nozzle 6b) to a temperature appropriate for bathroom cleaning. The user also moves any obstacles on the floor pan 50 of the washing area 5 out of the bathroom 9. The user also stores the lid of the bathtub 4 in a storage position along the left wall panel 90a or the front wall panel 90b, or moves it out of the bathroom 9. The user also opens the drain valve that opens and closes the drain outlet at the bottom of the bathtub body 40 of the bathtub 4 to drain the hot water from the bathtub 4.

[0071] Next, the user closes door 93 and operates operation unit 11 outside bathroom 9 to press the bathroom cleaning start button. Operation unit 11 then sends a control signal to control unit 10, which then controls control valves 15a, 15b, and 19 to open and pump 18 to drive or stop the pump. This causes control unit 10 to spray hot water containing detergent or hot water without detergent from bathtub cleaning nozzle 6a, and hot water without detergent from washing area cleaning nozzle 6b. At this time, notification device 13 issues a voice notification that bathroom cleaning has begun.

[0072] At this time, if the detection results of a detection unit such as open / close detection unit 12 sent to control unit 10 indicate that door 93 is open or that there is an obstacle above bathtub 4 or above floor pan 50 of washing area 5, or both, control unit 10 stops the spraying of hot water or the like from washing nozzles 6a, 6b. Then, notification device 13 notifies the user of the above situation by voice, urging the user to close door 93, move the obstacle, or both.

[0073] The control unit 10 causes the cleaning nozzles 6a, 6b to spray hot and cold water containing detergent or hot and cold water without detergent for a predetermined time in accordance with a program stored in the control unit 10. Specifically, the bathtub cleaning nozzle 6a alternately sprays hot and cold water containing detergent and hot and cold water without detergent onto the bathtub body 40 and flange 41 of the bathtub 4, and then finally sprays hot and cold water without detergent. Then, the washing area cleaning nozzle 6b sprays hot and cold water without detergent onto the top surface of the floor pan 50 of the washing area 5 and its surrounding area.

[0074] When a predetermined time has elapsed since the start of water spraying from the cleaning nozzles 6 a and 6 b, the control unit 10 closes the control valves 15 a, 15 b, and 19 to stop water spraying from the cleaning nozzles 6 a and 6 b. The notification device 13 then notifies the user that the bathroom cleaning has been completed.

[0075] In the bathroom cleaning system of the second embodiment described above, in addition to cleaning the washing area 5 with the washing area cleaning nozzle 6b, the bathtub 4 can also be cleaned with the bathtub cleaning nozzle 6a.

[0076] In the bathroom cleaning system of this embodiment, cleaning nozzles 6a and 6b are positioned above the bathtub 4 and the washing area 5, respectively, so that the bathtub 4 and the washing area 5 can be cleaned in a manner suitable for each.

[0077] That is, in the bathtub 4, washing with hot water containing detergent and washing with hot water without detergent are alternately performed to clean dirt such as sebum stains from the surface of the bathtub 4, and finally, the detergent remaining on the surface of the bathtub 4 can be rinsed away with hot water without detergent. Then, in the washing area 5, soap scum, sebum stains, etc. remaining in the washing area 5 can be rinsed away with hot water without detergent. In addition, each of the washing nozzles 6a and 6b makes it easy to clean the bathtub 4 and the washing area 5 as a whole. Furthermore, because water is sprayed toward the bathtub 4 from the bathtub washing nozzle 6a, which is positioned above the bathtub 4, it is easy to clean bathtubs 4 of various sizes and shapes.

[0078] In the bathroom cleaning system of this embodiment, the bathtub cleaning nozzle 6a and the washing area cleaning nozzle 6b are incorporated into the cover 8, and both cleaning nozzles 6a, 6b are positioned close to the top and bottom of the faucet body 3. Therefore, in the bathroom cleaning system of this embodiment, the faucet body 3, the bathtub cleaning nozzle 6a, and the washing area cleaning nozzle 6b can be positioned compactly in the top and bottom directions.

[0079] Furthermore, in the bathroom cleaning system of this embodiment, the components for spraying hot and cold water containing detergent from the bathtub cleaning nozzle 6a (i.e., the detergent tank 16, supply pipe 17, pump 18, and control valve 19) are housed within the cover 8. This prevents the above components from being exposed and deteriorating the appearance.

[0080] (Embodiment 3) Next, we will explain the bathroom cleaning system and faucet unit 7 of embodiment 3 shown in Figures 5 and 6. In the following, for the bathroom cleaning system and faucet unit 7 of embodiment 3, components similar to those of the bathroom cleaning system and faucet unit 7 of embodiment 1 will be assigned the same reference numerals and detailed explanations will be omitted, and components that differ will be explained in detail.

[0081] In the bathroom cleaning system of embodiment 3, the cleaning nozzle 6 is a single cleaning nozzle 6c that sprays water toward both the bathtub 4 and the washing area 5.

[0082] The cover 8 extends from above the bathtub 4 to above the washing area 5. The height H1 of the cover 8 from the floor of the washing area 5 (i.e., the upper surface of the floor pan 50) is higher than the height H2 of the flange 41 of the bathtub 4 from the floor of the washing area 5, and is, for example, 650 mm to 950 mm. In this embodiment, the height H1 is 680 mm.

[0083] The cleaning nozzle 6c is located above the end of the washing area 5 adjacent to the bathtub 4. The cleaning nozzle 6c is configured to spray water onto the upper surface of the floor pan 50 of the washing area 5 and its surroundings (i.e., the apron 42 and the lower part of the bathroom side wall 90), the concave bathtub body 40 of the bathtub 4, and the flange 41.

[0084] In this embodiment, the faucet body 3 is an electronic temperature control type in which the hot water temperature and flow rate are electrically controlled. Each of the control valves 102, 103 is an electromagnetic valve or an electric valve, and is electrically connected to the control unit 10.

[0085] A water temperature detection unit 106 is provided in the flow path connecting the control valves 102, 103 and the faucet body 3. The water temperature detection unit 106 is located downstream of the junction of the flow path connected to the water pipe 100 and the flow path connected to the hot water heater 101. The water temperature detection unit 106 is a thermistor or the like, and is electrically connected to the control unit 10, transmitting the detected temperature to the control unit 10. The control unit 10 performs feedback control to adjust the valve opening of the control valves 102, 103 based on the temperature detected by the water temperature detection unit 106, thereby supplying hot water at the desired temperature to the faucet body 3.

[0086] The bathroom cleaning system further includes a detergent tank 16 for supplying detergent to the hot and cold water supplied from the faucet body 3 to the cleaning nozzle 6c. The detergent tank 16 is incorporated into the cover 8. In this embodiment, the detergent tank 16 is connected to the cleaning nozzle 6c via a supply pipe 17. A pump 18 and a control valve 19 are provided along the supply pipe 17. The control valve 19 is, for example, a solenoid valve or an electric valve. The pump 18 and the control valve 19 are electrically connected to the control unit 10 and are controlled by the control unit 10. The detergent tank 16, supply pipe 17, pump 18, and control valve 19 are each housed within the cover 8.

[0087] In the washing nozzle 6c, hot water supplied through the water supply pipe 14 and detergent supplied through the supply pipe 17 are mixed to form hot water containing detergent. This allows hot water containing detergent to be sprayed from the washing nozzle 6c.

[0088] The control unit 10 controls the washing nozzle 6c to alternately spray hot water containing detergent and hot water not containing detergent, and then finally spray hot water not containing detergent.

[0089] Next, the operation of the bathroom cleaning system of the third embodiment will be described.

[0090] Before starting the bathroom flush, the user moves any obstacles on the floor pan 50 of the washing area 5 out of the bathroom 9. The user also stores the lid of the bathtub 4 in a storage position along the left wall panel 90a or the front wall panel 90b, or moves it out of the bathroom 9. The user also opens the drain valve that opens and closes the drain outlet at the bottom of the bathtub body 40 of the bathtub 4 to drain the hot water from the bathtub 4.

[0091] In this embodiment, the temperature of the hot water supplied from the faucet body 3 to the cleaning nozzle 6c can be automatically adjusted by the control unit 10, so there is no need for the user to operate the temperature adjustment button 30 on the faucet body 3 to change the temperature to that required for cleaning.

[0092] Next, the user closes door 93 and operates operation unit 11 outside bathroom 9 to press the bathroom wash start button. In this embodiment, when the bathroom wash start button is pressed, control unit 10 automatically controls the valve opening of control valves 102 and 103, thereby changing the temperature of hot water supplied from faucet body 3 to wash nozzle 6c to an appropriate temperature. When the bathroom wash start button is pressed, operation unit 11 sends a control signal to control unit 10, which then controls opening control valves 15 and 19 and driving or stopping pump 18, causing hot water containing detergent or hot water not containing detergent to be sprayed from wash nozzle 6c. At this time, notification device 13 issues an audio notification that the bathroom wash has started.

[0093] At this time, if the detection results of a detection unit such as the open / close detection unit 12 sent to the control unit 10 indicate that the door 93 is open or that there is an obstacle above the bathtub 4 or above the floor pan 50 of the washing area 5, or both, the control unit 10 stops the spraying of hot water or the like from the washing nozzle 6c. Then, the notification device 13 notifies the user of the above situation by voice, urging the user to close the door 93, move the obstacle, or both.

[0094] The control unit 10 causes the cleaning nozzle 6c to spray hot and cold water containing detergent or hot and cold water without detergent for a predetermined time in accordance with a program stored in the control unit 10. In this embodiment, the cleaning nozzle 6c alternately sprays hot and cold water containing detergent and hot and cold water without detergent onto the bathtub body 40, flange 41, and upper surface of the floor pan 50 of the washing area 5 of the bathtub 4, and their surroundings (i.e., the apron 42 and the lower part of the bathroom side wall 90). Then, finally, the cleaning nozzle 6c sprays hot and cold water without detergent.

[0095] When a predetermined time has elapsed since the start of water spraying from the cleaning nozzle 6c, the control unit 10 closes the control valve 15 to stop water spraying from the cleaning nozzle 6c. The notification device 13 then notifies the user that the bathroom cleaning has been completed.

[0096] In the bathroom cleaning system of embodiment 3 described above, a single cleaning nozzle 6c can clean both the bathtub 4 and the washing area 5, thereby reducing the number of parts compared to when separate cleaning nozzles are provided for the bathtub 4 and the washing area 5.

[0097] In addition, in the bathroom cleaning system of embodiment 3, hot water containing detergent and hot water not containing detergent can be sprayed alternately from the cleaning nozzle 6c onto both the bathtub 4 and the washing area 5, thereby providing a high cleaning effect on both the bathtub 4 and the washing area 5.

[0098] In addition, in the bathroom cleaning system of embodiment 3, by pressing the bathroom cleaning start button on the operating unit 11, the temperature of the hot water supplied from the faucet body 3 to the cleaning nozzle 6c can be automatically adjusted to an appropriate temperature, thereby eliminating the need to operate the temperature adjustment button 30 inside the bathroom 9.

[0099] (Modifications) Next, we will explain modifications of the bathroom 9, bathroom cleaning system, and faucet unit 7 of the above-mentioned Embodiments 1 to 3. The modifications shown below can be combined as appropriate.

[0100] The bathroom cleaning systems of embodiments 1 and 2 may be configured so that the temperature of the hot and cold water supplied to the faucet body 3 is automatically controlled by the control unit 10, as in the bathroom cleaning system of embodiment 3.

[0101] In the bathroom cleaning systems of the second and third embodiments, the drain plug that opens and closes the drain outlet of the bathtub 4 may be controlled by the control unit 10. In this case, hot water containing detergent or hot water without detergent that has been sprayed into the bathtub 4 can be reliably drained.

[0102] In the bathroom cleaning system of embodiment 1, the cover 8 may be arranged to extend from above the bathtub 4 to above the washing area 5.

[0103] The bathroom cleaning system of embodiment 1 may include a detergent tank 16, a supply pipe 17, a pump 18, and a control valve 19, similar to the bathroom cleaning system of embodiment 3. In other words, the washing area 5 may be cleaned by alternately spraying hot and cold water containing detergent and hot and cold water not containing detergent.

[0104] The bathroom 9 in the first to third embodiments may have only one of the shower hose 1 and the water outlet 2. Furthermore, the bathroom 9 in the first embodiment may be a shower room without a bathtub 4.

[0105] The bathroom cleaning system of the second and third embodiments may not have the detergent tank 16, and the bathtub 4 may be cleaned using only hot water without detergent.

[0106] Furthermore, the bathroom cleaning system of embodiment 2 does not need to be equipped with the pump 18 and the control valve 19, and other structures such as a Venturi tube may be used to mix the detergent in the detergent tank 16 with the hot water.

[0107] In the bathroom cleaning systems of Embodiments 1 to 3, cleaning nozzle 6 (i.e., cleaning nozzles 6a, 6b, and 6c) may be movable, and the direction of the spray nozzle at the tip of cleaning nozzle 6 may be changed to clean a predetermined area. For example, cleaning nozzle 6 (specifically, washing area cleaning nozzle 6b) may be movable so as to spray water onto the lower part of the right bathroom side wall 90 (i.e., the right wall panel 90a), the upper surface of the floor pan 50 of washing area 5, and the lower part of the apron 42 of bathtub 4, in that order. Furthermore, cleaning nozzle 6 (i.e., cleaning nozzles 6a, 6b, and 6c) may be movable in the longitudinal direction of cover 8 (i.e., the left-right direction), thereby allowing cleaning of a predetermined area.

[0108] In the bathroom cleaning system of embodiments 2 and 3, the cover 8 may be positioned only above the washing area 5.

[0109] In the bathroom cleaning system of embodiments 1 and 2, the cleaning nozzle 6 (specifically, the washing area cleaning nozzle 6b) may be configured to spray water only toward the floor surface of the washing area 5, and not toward the surrounding area of ​​this floor surface.

[0110] In the bathroom cleaning systems of embodiments 1 to 3, the top surface 810 of the cover 8 may be configured so that bathroom products such as soap, shampoo, etc. cannot be placed on it. For example, the top surface 810 of the cover 8 may be configured to have a large incline, or may be configured so short in the front-to-rear direction that bathroom products cannot be placed on it.

[0111] In the bathroom cleaning systems of embodiments 1 to 3, the height H1 of the top surface 810 of the cover 8 from the floor surface of the washing area 5 is not limited to 450 mm or more and 950 mm or less, and may be in other ranges.

[0112] The bathroom cleaning systems of embodiments 1 to 3 do not have to be provided with an operation unit 11 that is located outside bathroom 9 and can be operated by a user. For example, the bathroom cleaning systems of embodiments 1 to 3 may be configured so that control unit 10 automatically sprays water from cleaning nozzles 6 (i.e., cleaning nozzles 6a, 6b, 6c) when the user leaves bathroom 9.

[0113] The bathroom cleaning systems of embodiments 1 to 3 may not have open / close detection unit 12. Furthermore, the bathroom cleaning systems of embodiments 1 to 3 may not have notification device 13. The bathroom cleaning systems of embodiments 1 to 3 may not have a detection unit that detects obstacles in bathroom 9. Obstacles in the bathroom may be seen and removed by a person.

[0114] In the bathroom cleaning systems of embodiments 2 and 3, the control unit 10 is not limited to a system that controls the cleaning nozzles 6 (i.e., the cleaning nozzles 6b and 6c) to alternately spray hot and cold water containing detergent and hot and cold water not containing detergent, and then spray hot and cold water not containing detergent to end the cleaning. For example, the control unit 10 may be configured to control the cleaning nozzles 6 (specifically, the cleaning nozzles 6b and 6c) to spray hot and cold water containing detergent once, and then spray hot and cold water not containing detergent multiple times to end the cleaning.

[0115] In the bathroom cleaning systems of the second and third embodiments, the control unit 10 may have a first cleaning mode in which hot and cold water containing detergent and hot and cold water not containing detergent are alternately sprayed from the cleaning nozzle 6, and a second cleaning mode in which only hot and cold water not containing detergent is sprayed from the cleaning nozzle 6. One of the first cleaning mode and the second cleaning mode may be selectable by operating the operation unit 11. In this case, at least one of the bathtub 4 and the washing area 5 can be cleaned depending on the cleaning mode selected by the user.
