Description

Aspects of the present invention relate generally to sanitary washing devices.

It is known in conventional sanitary flushing devices to spray water into the toilet bowl before or after the user uses the toilet. As a result, it is possible to prevent dirt from sticking to the bowl and to remove dirt adhering to the bowl. For example, in Patent Document 1, a nozzle is provided with two ejection ports, and the nozzle is advanced into a bowl to eject water from the ejection ports, or the nozzle is housed to eject water from the ejection ports. This allows water to reach a wider area of the bowl. On the other hand, if the nozzle is capable of ejecting water over a wide area, it may take a long time to eject water.

Patent No. 6741219

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sanitary washing device capable of jetting water in a short period of time.

A first aspect of the invention is a nozzle for washing a human body part, comprising a casing and a plurality of nozzles that are movable between a housing position that is housed in the casing and an advanced position that is advanced from the casing, and that discharge water. A nozzle having an ejection port and a flow path switching mechanism for switching a flow path of water supplied to the nozzle, comprising: a fixed disk having a plurality of supply holes; and a movable disk having openings overlapping the fixed disk and the flow path switching mechanism having, the plurality of jet ports include a plurality of private part washing jet ports that jet water upward, and a first jet jet that jets water forward and downward. and a second jetting port for jetting water backward from the first jetting port, wherein the plurality of supply holes communicate with the plurality of jetting ports for washing private parts. a supply hole, a first supply hole communicating with the first ejection port, and a second supply hole communicating with the second ejection port, and the flow path switching mechanism fixes the movable disk to the fixed By rotating with respect to the disk, the opening and the first supply hole are communicated to supply water to the first ejection port, and the opening and the second supply hole are communicated to communicate the second supply hole. It is possible to switch between a state in which water is supplied to the spout and a state in which the opening is communicated with at least one of the plurality of private parts washing supply holes and water is supplied to at least one of the plurality of private parts washing spouts. and has an operation of supplying water to the first ejection port and the second ejection port before and/or after use by the user, and among the plurality of supply holes, the first supply hole and the second The two supply holes are a sanitary washing device characterized in that they are adjacent in the circumferential direction of the fixed disk.

According to this sanitary washing device, since water is jetted from the first jetting port and the second jetting port provided on the nozzle before and/or after use by the user, the water can be jetted over a wide range. can. Since the first supply hole and the second supply hole are adjacent to each other in the fixed disk, it is possible to quickly switch between the state of jetting water from the first jet port and the state of jetting water from the second jet port. can be done. Therefore, it becomes possible to jet water over a wide range in a short time. By stopping the jetting of water in a short period of time before and/or after using the toilet, it is possible, for example, to prevent the next user from being splashed with water from the jetting port.

A second invention is the sanitary washing device according to the first invention, wherein the second supply hole has a groove channel extending in the circumferential direction of the fixed disk.

According to this sanitary washing device, by adjusting the length of the groove channel, the length of time during which water is ejected from the first ejection port and the second ejection port can be adjusted without stopping the rotation of the movable disk in the circumferential direction. You can adjust the time the water is ejected from the

In a third aspect based on the first or second aspect, the channel switching mechanism regulates the rotation of the movable disk in the circumferential direction, thereby defining the origin position of the rotation of the movable disk in the circumferential direction. When the movable disk is at the origin position, the opening and the first supply hole communicate with each other, or the opening and the second supply hole communicate with each other and the second supply hole communicates with the opening. The sanitary washing device is characterized in that the first supply hole and the second supply hole are adjacent to each other without the stopper interposed therebetween.

According to this sanitary washing device, the origin position can be reliably defined by the stopper. It becomes easy to spout water to.

In a fourth aspect based on the third aspect, the plurality of supply holes further have a bypass supply hole different from the plurality of private parts washing jet ports, and the movable disk is moved from the origin position to the stopper. The opening communicates with the bypass supply hole next to the first supply hole or the second supply hole among the plurality of supply holes when rotated in a direction opposite to the direction of rotation restricted by the It is a sanitary washing device characterized by:

According to this sanitary washing device, the opening of the movable disk communicates with the bypass supply hole next to the first and second supply holes, so that the first and second jets jet water and the bypass jets When switching between the state of jetting water and the state of jetting water, the opening does not communicate with the private parts washing supply hole, and the private parts washing jet port does not jet water. Therefore, even if the state in which the nozzle is advanced without being housed and the state in which the first and second jets are ejected and the state in which the bypass jet is ejected, the water from the private part washing ejection port can be switched. Water leakage does not occur. As a result, the nozzle does not need to be accommodated every time switching between the state in which the first and second ejection ports eject water and the state in which the bypass ejection port ejects water, so the number of times the nozzle is driven can be reduced. can be suppressed.

An aspect of the present invention provides a sanitary washing device capable of jetting water in a short period of time.

In the following description of the embodiments, the terms "upper", "lower", "forward", "backward", "rightward" and "leftward" are used, and these directions, as represented in FIG. This is the direction viewed from the user sitting on the toilet seat 200 .

Inside the casing 400, there is built-in a private part washing function unit that realizes washing of the private parts such as the "buttocks" of the user sitting on the toilet seat 200, and the like. The local cleansing function includes nozzles 473 . The nozzle 473 is movable between a housed position housed in the casing 400 and an advanced position advanced from the casing 400 . The nozzle 473 advances along a straight track towards the center of the bowl 801 positioned at the lower front of the casing 400 and retreats along a straight track towards the inside of the casing 400 positioned rearward above the bowl 801 . Note that the sanitary washing device 100 shown in FIG. 1 shows a state where the nozzle 473 is at the advanced position.

The sanitary washing device 100 is provided with a seating detection sensor 404 (see FIG. 2) that detects the seating of the user on the toilet seat 200 . When the seating detection sensor 404 detects the user sitting on the toilet seat 200, the user operates the operation unit 500 (see FIG. 2) such as a remote controller to advance the nozzle 473 to the advanced position or retract it. You can move it back into position.

The nozzle 473 has a plurality of ejection ports (water ejection ports) for ejecting water. The plurality of jets has a plurality of private cleaning jets 474 that jet water upward. The nozzle 473 , in a state of being protruded from the casing 400 , discharges water (cleansing water) from the private parts washing jet port 474 toward the human private part to wash the human private part. Specifically, as a plurality of private part washing jet ports 474 (water jets), a buttocks washing jet port 474a, a soft washing jet port 474b, and a bidet washing jet port 474c are provided. The nozzle 473 can jet water from a bottom washing spout 474a or a soft washing spout 474b provided at its tip to wash the "bottom" of the user sitting on the toilet seat 200. FIG. Alternatively, the nozzle 473 can jet water from a bidet washing spout 474c provided at its tip to wash the private parts of a woman sitting on the toilet seat 200. FIG. In the specification of the present application, "water" includes not only cold water but also heated hot water.

Modes for washing the "bottom" include, for example, "bottom washing" and "soft washing" for gently washing with a water flow that is softer than the "bottom washing". The nozzle 473 can perform, for example, "bottom washing", "soft washing", and "bidet washing".

In the nozzle 473 shown in FIG. 1, the bidet washing spout 474c is provided closer to the tip of the nozzle 473 than the soft washing spout 474b, and the soft washing spout 474b is located closer to the nozzle 473 than the bottom washing spout 474a. However, the installation positions of the bottom washing spout 474a, the soft washing spout 474b, and the bidet washing spout 474c are not limited to this. In addition, although the nozzle 473 shown in FIG. 1 is provided with three spouts, for example, the soft washing spout 474b may be omitted, or four or more spouts may be provided. good.

FIG. 2 is a block diagram schematically showing the main configuration of the sanitary washing device according to the embodiment.
FIG. 2 also shows the main configuration of the waterway system and the electrical system.
As shown in FIG. 2 , the sanitary washing device 100 has a water guide section 20 . The water guide section 20 has a conduit 20a from a water supply source 10 such as a tap or a water storage tank to the nozzle 473 . The water guide section 20 guides the water supplied from the water supply source 10 to the nozzle 473 through the conduit 20a. The pipe line 20a is formed by, for example, parts such as an electromagnetic valve 431, a heat exchanger unit 440, and a flow path switching part 472, which will be described below, and a plurality of pipes connecting these parts.

A solenoid valve 431 is provided on the upstream side of the water guide section 20 . The electromagnetic valve 431 is an electromagnetic valve that can be opened and closed, and controls water supply based on a command from the control unit 405 provided inside the casing 400 . In other words, the electromagnetic valve 431 opens and closes the pipeline 20a. By opening the electromagnetic valve 431, the water supplied from the water supply source 10 flows into the pipeline 20a.

A pressure regulating valve 432 is provided downstream of the solenoid valve 431 . The pressure regulating valve 432 regulates the pressure in the pipeline 20a to within a predetermined pressure range when the water supply pressure is high. A check valve 433 is provided downstream of the pressure regulating valve 432 . The check valve 433 suppresses backflow of water to the upstream side of the check valve 433 when the pressure in the pipeline 20a is reduced.

A heat exchanger unit 440 (heating section) is provided downstream of the check valve 433 . The heat exchanger unit 440 has a heater and heats the water supplied from the water supply source 10 to e.g. That is, the heat exchanger unit 440 produces hot water.

The heat exchanger unit 440 is an instantaneous heating type (instantaneous type) heat exchanger using, for example, a ceramic heater. An instantaneous heating type heat exchanger can raise the temperature of water to a specified temperature in a short time compared to a hot water storage heating type heat exchanger using a hot water storage tank. Note that the heat exchanger unit 440 is not limited to an instantaneous heating type heat exchanger, and may be a hot water storage heating type heat exchanger. Moreover, the heating unit is not limited to the heat exchanger, and may use other heating methods such as microwave heating.

The heat exchanger unit 440 is connected with the controller 405 . The control unit 405 raises the temperature of the water to the temperature set by the operation unit 500 by controlling the heat exchanger unit 440 according to the operation of the operation unit 500 by the user, for example.

A flow rate sensor 442 is provided downstream of the heat exchanger unit 440 . Flow sensor 442 detects the flow rate of water discharged from heat exchanger unit 440 . That is, the flow rate sensor 442 detects the flow rate of water flowing through the conduit 20a. The flow sensor 442 is connected to the controller 405 . The flow rate sensor 442 inputs the detection result of the flow rate to the control unit 405 .

A vacuum breaker (VB) 452 is provided downstream of the flow rate sensor 442 . The vacuum breaker 452 has, for example, a channel for flowing water, an intake port for taking air into the channel, and a valve mechanism for opening and closing the intake port. For example, the valve mechanism closes the intake port when water is flowing through the channel, and opens the intake port to take air into the channel when the flow of water stops. That is, the vacuum breaker 452 draws air into the conduit 20a when there is no water flow in the water conduit 20. As shown in FIG. A float valve, for example, is used for the valve mechanism.

The vacuum breaker 452 draws air into the pipeline 20a as described above, thereby facilitating draining of the downstream portion of the pipeline 20a from the vacuum breaker 452, for example. Vacuum breaker 452 facilitates draining nozzle 473, for example. In this way, the vacuum breaker 452 extracts water from the nozzle 473 and takes air into the nozzle 473, so that, for example, cleaning water in the nozzle 473 and dirty water accumulated in the bowl 801 can be removed from the water supply source 10 ( It suppresses backflow to the water supply side.

An electrolytic cell unit 450 is provided downstream of the vacuum breaker 452 . The electrolytic cell unit 450 electrolyzes the tap water flowing inside to generate a liquid containing hypochlorous acid (functional water) from the tap water. The electrolytic cell unit 450 is connected to the controller 405 . The electrolytic cell unit 450 generates functional water under the control of the controller 405 .

The functional water generated in the electrolytic cell unit 450 may be, for example, a solution containing metal ions such as silver ions and copper ions. Alternatively, the functional water generated in the electrolytic cell unit 450 may be a solution containing electrolytic chlorine, ozone, or the like. Alternatively, the functional water generated in the electrolytic cell unit 450 may be acidic water or alkaline water.

A flow rate adjusting section 471 is provided downstream of the electrolytic cell unit 450 . The flow rate adjustment unit 471 adjusts the water force (flow rate). A channel switching unit 472 is provided downstream of the flow rate adjusting unit 471 . The channel switching unit 472 switches the channel of water supplied to the nozzle 473 and the nozzle cleaning unit 478 and opens and closes the water supply. The flow rate adjusting section 471 and the channel switching section 472 may be provided as one unit. The flow rate adjusting section 471 and the channel switching section 472 are connected to the control section 405 . Operations of the flow rate adjusting unit 471 and the flow switching unit 472 are controlled by the control unit 405 .

A nozzle 473 and a nozzle cleaning unit 478 are provided downstream of the channel switching unit 472 . The nozzle 473 receives a driving force from the nozzle driving portion 476 and advances into the bowl 801 of the toilet bowl 800 or retreats from the bowl 801 .

The nozzle cleaning unit 478 cleans the outer peripheral surface (body) of the nozzle 473 by, for example, jetting functional water or water from a later-described bypass jet port 478a (see FIG. 3).

In addition, downstream of the channel switching portion 472, there is a buttocks washing channel 21 that supplies the nozzle 473 with water supplied from the water supply source 10 via the water guide portion 20 or functional water generated in the electrolytic cell unit 450. , a soft cleansing channel 22 and a bidet cleansing channel 23 are provided. The bottom washing flow path 21 connects the flow path switching portion 472 and the bottom washing spout 474a. The soft wash flow path 22 connects the flow path switching portion 472 and the soft wash spout 474b. The bidet washing channel 23 connects the channel switching portion 472 and the bidet washing spout 474c.

Further, downstream of the flow path switching section 472, the surface cleaning flow path 24, the first bowl ejection flow path 25, and the second bowl ejection flow path 26 are provided. The surface cleaning flow path 24 guides the water supplied from the water supply source 10 through the water guide section 20 and the functional water generated in the electrolytic cell unit 450 to the water discharge section of the nozzle cleaning section 478 . The surface cleaning channel 24 connects the channel switching portion 472 and the bypass ejection port 478a. The first bowl ejection channel 25 is connected to a first ejection port 479a (see FIG. 3) provided in the nozzle, which will be described later. The second bowl ejection channel 26 is connected to a second ejection port 479b (see FIG. 3) provided in the nozzle, which will be described later. The first bowl ejection channel 25 and the second bowl ejection channel 26 pass water supplied from the water supply source 10 through the water guide part 20 and functional water generated in the electrolytic cell unit 450 through the first ejection port 479a and the second bowl ejection channel 26. It guides to the second ejection port 479b. The water or functional water supplied to the first ejection port 479a and the second ejection port 479b is ejected toward the bowl 801 from the first ejection port 479a and the second ejection port 479b.

The control unit 405 controls the flow path switching unit 472 so that the bottom washing flow path 21, the soft washing flow path 22, the bidet washing flow path 23, the surface washing flow path 24, the first bowl jetting flow path 25, and the second Switches opening and closing of each channel of the two-bowl ejection channel 26 . Thus, the flow path switching unit 472 has a plurality of outlets such as the buttocks washing outlet 474a, the soft washing outlet 474b, the bidet washing outlet 474c, the bypass outlet 478a, the first outlet 479a and the second outlet 479b. For each water port, switching is made between a state in which it is communicated with the pipeline 20a and a state in which it is not communicated with the pipeline 20a.

The control unit 405 is supplied with power from the power supply circuit 401, and based on signals from the seating detection sensor 404, the flow sensor 442, the operation unit 500, and the like, operates the solenoid valve 431, the heat exchanger unit 440, and the electrolytic cell. It controls the operations of the unit 450, the flow rate adjusting section 471, the channel switching section 472, the nozzle driving section 476, and the like. Thereby, the controller 405 controls the operation of the nozzle 473 . The control unit 405 is an electric circuit including an integrated circuit such as a microcomputer.

The casing 400 also has various functions such as a "warm air drying function" for blowing warm air toward the "buttocks" of the user sitting on the toilet seat 200 to dry them, a "deodorizing unit", and an "indoor heating unit". Mechanisms may be provided accordingly. At this time, an exhaust port 407 from the deodorizing unit and an exhaust port 408 from the indoor heating unit are appropriately provided on the side surface of the casing 400 . However, in the present invention, the sanitary washing function part and other additional function parts may not necessarily be provided.

3(a) and 3(b) are perspective views illustrating nozzles of the sanitary washing device according to the embodiment.
FIG. 3(b) shows an enlarged view of the region R shown in FIG. 3(a). A nozzle head 473a at the tip of the nozzle 473 has a plurality of private parts washing spouts 474 (bottom washing spout 474a, soft washing spout 474b, and bidet washing spout 474c), a first spout 479a, and a second spout 474c. A jet port 479b is provided.

As shown in FIG. 3A , a nozzle cleaning section 478 (nozzle cleaning chamber) is provided on the outer peripheral portion of the nozzle 473 . The nozzle cleaning part 478 has a bypass jetting port 478 a that supplies water to the outer peripheral surface of the nozzle 473 . For example, the position of nozzle washer 478 is fixed with respect to casing 400 . When the nozzle 473 advances and retreats with respect to the casing 400 , the nozzle 473 moves back and forth with respect to the nozzle cleaning section 478 . For example, water is ejected from the bypass ejection port 478a while moving the nozzle 473 forward and backward. This water can wash the outer peripheral surface of the nozzle 473 . The bypass jet port 478a jets water into the nozzle cleaning part 478 (nozzle cleaning chamber), for example, and does not jet water toward the user or the bowl 801 in front.

The first ejection port 479a and the second ejection port 479b are arranged side by side. The first jetting port 479 a and the second jetting port 479 b jet water toward the bowl 801 .

4(a) and 4(b) are cross-sectional views illustrating the periphery of the nozzle of the sanitary washing device according to the embodiment.
These figures show the periphery of the nozzle 473 in the cross section taken along line A1-A2 shown in FIG. 4A shows a state in which water is jetted from the first jet port 479a, and FIG. 4B shows a state in which water is jetted from the second jet port 479b.

The nozzle 473 has, for example, a nozzle head 473a and a nozzle cover 473b. The nozzle head 473a is housed inside the nozzle cover 473b. A shielding plate 600 is provided in the front portion of the casing 400 . The shielding plate 600 is rotatable around an axis 600a. The nozzle 473 is located behind the shielding plate 600 and does not come into contact with the shielding plate 600 when it is in the retracted most retracted position. When the nozzle 473 advances forward from the storage position along the advance direction ED, the tip of the nozzle 473 comes into contact with the shielding plate 600 and rotates the shielding plate 600 so as to push it up. The nozzle 473 is positioned below the shielding plate 600 when it is in the advanced position where it is advanced from the casing 400 . A drive unit for automatically rotating the shielding plate 600 may be provided separately.

The first jetting port 479a and the second jetting port 479b jet misty water, for example. For example, the first ejection port 479a sprays in a substantially conical shape with the position of the first ejection port 479a as the apex. For example, the second ejection port 479b sprays in a substantially conical shape with the position of the second ejection port 479b as the apex. The particle size of the water ejected from the first ejection port 479a and the second ejection port 479b is, for example, larger than the particle size of the water ejected from the buttocks washing spout 474a, the soft washing spout 474b, and the bidet washing spout 474c. is also small. The particle size of water ejected from the first ejection port 479a and the second ejection port 479b is, for example, approximately 400 μm.

As shown in FIG. 4A, the first ejection port 479a opens forward and downward. The first ejection port 479a ejects water forward and downward. More specifically, the first ejection port 479a ejects water at a first ejection angle θ1 with respect to the horizontal plane HP. The first ejection angle θ1 is the angle between the first ejection direction D1 of water ejected from the first ejection port 479a and the horizontal plane HP. The first ejection direction D1 can be represented, for example, by the center line of the ejection range R1 of water ejected from the first ejection port 479a. The first ejection direction D1 may be represented, for example, by a normal line of the first ejection port 479a.

The first ejection angle θ1 is, for example, greater than the extension angle θ3 of the nozzle 473 with respect to the horizontal plane HP. The advance angle θ3 is the angle formed by the advance direction ED of the nozzle 473 and the horizontal plane HP. In other words, the first jetting port 479a jets water backward from the advancing direction ED of the nozzle 473, for example. The first ejection angle θ1 is an acute angle. The first ejection angle θ1 is, for example, 38 degrees or more and 72 degrees or less.

As shown in FIG. 4B, the second ejection port 479b opens further rearward than the first ejection port 479a. The second jetting port 479b jets water backward from the first jetting port 479a. More specifically, the second ejection port 479b ejects water at a second ejection angle θ2 with respect to the horizontal plane HP. The second ejection angle θ2 is the angle between the second ejection direction D2 of water ejected from the second ejection port 479b and the horizontal plane HP. The second ejection direction D2 can be represented, for example, by the center line of the ejection range R2 of water ejected from the second ejection port 479b. The second ejection direction D2 may be represented, for example, by a normal line of the second ejection port 479b.

The second ejection angle θ2 is, for example, greater than the extension angle θ3 of the nozzle 473 with respect to the horizontal plane HP. In other words, the second jetting port 479b jets water backward from the advancing direction ED of the nozzle 473, for example. The second ejection angle θ2 is greater than the first ejection angle θ1. In other words, the second ejection port 479b ejects water more rearward than the first ejection port 479a. The second ejection angle θ2 is, for example, 72 degrees or more and 90 degrees or less.

Thus, by providing two ejection ports (the first ejection port 479a and the second ejection port 479b) that eject water in different directions in the front-rear direction, water can adhere to a wider range of the bowl 801. . More specifically, water adheres to the front side of the bowl 801 from the first jet port 479a that jets water forward and downward, and the second jet port 479a jets water backward from the first jet port 479a. Water can be attached to the rear side of the bowl 801 by the spout 479b. As a result, the water ejected from the second ejection port 479b can adhere to the rear side of the bowl 801 to which the water ejected from the first ejection port 479a is less likely to adhere, and the water can adhere to a wider range of the bowl 801. can be made

FIG. 5 is a schematic diagram illustrating a channel switching unit of the sanitary washing device according to the embodiment;
As shown in FIG. 5 , the flow path switching section 472 (flow path switching mechanism) has a fixed disk (stator) 80 , a movable disk (rotor) 82 , a housing 84 and a drive mechanism 86 .

The stationary disk 80 is, for example, disk-shaped, and has a front surface 80a (surface facing upstream) and a back surface 80b (surface facing downstream) on the opposite side of the front surface 80a. The fixed disk 80 is provided with a plurality of supply holes (such as a first supply hole 91, a second supply hole 92, a bypass supply hole 93, and a plurality of private cleaning supply holes, which will be described later with reference to FIG. 6). Each of the plurality of supply holes is connected to a plurality of flow paths provided downstream (bottom washing flow path 21, soft washing flow path 22, bidet washing flow path 23, surface washing flow path 24, first bowl jetting flow path 25 and It is connected with each of the second bowl ejection channels 26).

The movable disk 82 is, for example, a circular disk having a diameter similar to that of the fixed disk 80 . The movable disk 82 is provided upstream of the fixed disk 80 . The movable disk 82 has a front surface 82a (upstream facing surface) and a back surface 82b (downstream facing surface) opposite to the front surface 82a. A movable disk 82 overlaps the fixed disk 80 . In other words, the back surface 82 b of the movable disk 82 faces the front surface 80 a of the fixed disk 80 . The movable disk 82 contacts the front surface 80 a of the fixed disk 80 . The movable disk 82 has openings 98 (a first opening 98a and a second opening 98b described below with respect to FIG. 7) corresponding to the plurality of feed holes of the fixed disk 80. As shown in FIG.

The movable disk 82 slides and rotates on the front surface 80a in the circumferential direction, with the direction orthogonal to the front surface 80a as an axis (hereinafter referred to as a rotation axis RA). When the opening 98 of the movable disk 82 overlaps one of the supply holes provided in the fixed disk 80 , another supply hole of the fixed disk 80 is blocked by the movable disk 82 . This allows water to flow only through the supply holes overlapping the openings 98 of the movable disk 82 .

The flow path switching unit 472 selectively switches the supply holes of the fixed disk 80 through which water can flow by rotating the movable disk 82 to overlap the opening 98 with at least one of the plurality of supply holes. As a result, the bottom cleaning channel 21, the soft cleaning channel 22, the bidet cleaning channel 23, the surface cleaning channel 24, the first bowl jetting channel 25, and the second bowl jetting channel 26 are arranged according to the selected supply hole. can be selectively supplied with water.

The housing 84 has, for example, a cylindrical shape, and accommodates the fixed disk 80 and the movable disk 82 in an internal space. A housing 84 rotatably supports the movable disk 82 . Water is supplied from the upstream side of the flow path switching portion 472 to the internal space of the housing 84 upstream of the movable disk 82 . The water is supplied from the inner space of the housing 84 to each channel through the movable disk 82 and the fixed disk 80 .

The drive mechanism 86 has an electric motor such as a motor or a solenoid, and rotates the movable disk 82 by supplying driving force to the movable disk 82 . The drive mechanism 86 is connected to the controller 405 and rotates the movable disk 82 under the control of the controller 405 . The controller 405 drives the drive mechanism 86 to rotate the movable disk 82 and selects at least one of the supply holes of the fixed disk 80 to switch the destination of the water. It should be noted that the drive mechanism 86 may be any mechanism capable of rotating the movable disk 82 without causing water leakage.

The flow path switching section 472 further has a stopper mechanism 87 . The stopper mechanism 87 has a stopper 88 which will be described later with respect to FIG. The stopper 88 regulates the rotation of the movable disk 82 in the circumferential direction, thereby defining the origin of rotation of the movable disk 82 in the circumferential direction.

6(a) to 6(c) are a plan view and a perspective view illustrating the fixed disk of the channel switching unit of the sanitary washing device according to the embodiment.
6A is a plan view showing the front surface 80a side, FIG. 6B is a plan view showing the rear surface 80b side, and FIG.
The fixed disk 80 has a first supply hole 91 , a second supply hole 92 , a plurality of supply holes for washing private parts (bidet supply hole 94 , bottom supply hole 95 , soft supply hole 96 ), and bypass supply hole 93 .

The first supply hole 91 and the second supply hole 92 are provided adjacent to each other in the circumferential direction of the fixed disk 80 among the plurality of supply holes provided in the fixed disk 80 . In other words, no other supply holes (the bypass supply hole 93 and the private parts washing supply hole) are arranged between the first supply hole 91 and the second supply hole 92 in the circumferential direction of the fixed disk 80 .

In this example, the plurality of supply holes are arranged in the order of the first supply hole 91, the second supply hole 92, the bidet supply hole 94, the bottom supply hole 95, the bypass supply hole 93, and the soft supply hole 96 in the circumferential direction of the fixed disk. are lined up.

The second supply hole 92 is connected to the second bowl ejection channel 26 and communicates with the second ejection port 479b via the second bowl ejection channel 26 . The bypass supply hole 93 is connected to the surface cleaning channel 24 and communicates with the bypass ejection port 478a via the surface cleaning channel 24 .

Each of the plurality of private parts washing supply holes is connected to each of the plurality of private parts washing spouts. More specifically, the bidet supply hole 94 is connected to the bidet cleaning channel 23 and communicates with the bidet cleaning spout 474c via the bidet cleaning channel 23 . The buttocks supply hole 95 is connected to the bottom washing flow path 21 and communicates with the bottom washing spout 474a via the bottom washing flow path 21 . The soft cleaning supply hole 96 is connected to the soft cleaning channel 22 and communicates with the soft cleaning spout 474b via the soft cleaning channel 22 .

The range of supply holes may include not only through holes but also groove channels connected to through holes.
For example, the second supply hole 92 has a through hole 92a and a groove channel 92b. The groove channel 92b is a groove provided in the front surface 80a, extends in the circumferential direction of the fixed disk 80, and is connected to the through hole 92a.
The bidet supply hole 94 has a through hole 94a and a groove channel 94b. The groove channel 94b is a groove provided in the front surface 80a, extends in the circumferential direction of the fixed disk 80, and is connected to the through hole 94a.
The buttocks supply hole 95 has a through hole 95a and a groove channel 95b. The groove channel 95b is a groove provided in the front surface 80a, extends in the circumferential direction of the fixed disk 80, and is connected to the through hole 95a.
The soft supply hole 96 has a through hole 96a and a groove channel 96b. The groove channel 96b is a groove provided in the front surface 80a, extends in the circumferential direction of the fixed disk 80, and is connected to the through hole 96a.
The first supply hole 91 has a through hole 91a, and the bypass supply hole 93 has a through hole 93a. In this example, the first supply hole 91 and the bypass supply hole 93 are not provided with groove channels, but the first supply hole 91 and the bypass supply hole 93 may be provided with groove channels as appropriate. .

7(a) to 7(c) are a plan view and a perspective view illustrating the movable disk of the channel switching unit of the sanitary washing device according to the embodiment.
7A is a plan view showing the front surface 82a side, FIG. 7B is a plan view showing the rear surface 82b side, and FIG.

As shown in FIGS. 7(a) to 7(c), the movable disk 82 has an opening 98. FIG. The opening 98 may have multiple openings. In this example, the openings 98 include a first opening 98a and a second opening 98b. Each of the first opening 98a and the second opening 98b extend through the movable disk 82 from the front surface 82a to the rear surface 82b. In addition, the range of opening includes the notch part which notched a circular part here. For example, the first opening 98a is a notch formed by cutting the outer circumference of the circular movable disk 82 .

The second opening 98b is provided on the opposite side of the first opening 98a when viewed from the rotation center 82c of the movable disk 82. As shown in FIG. The first opening 98a is located closer to the outer circumference of the movable disk 82 than the second opening 98b. The opening area of the first opening 98a is larger than the opening area of the second opening 98b.

FIG. 8 is a plan view illustrating the stopper mechanism of the channel switching portion of the sanitary washing device according to the embodiment.
As shown in FIG. 8, the stopper mechanism 87 has a first member 87a and a second member 87b. In this example, the planar shapes of the first member 87a and the second member 87b are generally circular, and the second member 87b is arranged on the inner peripheral side of the first member 87a.

The stopper 88 restricts the circumferential rotation of the movable disk 82 . In this example, the stopper 88 is composed of a first stopper portion 88a and a second stopper portion 88b. The first stopper portion 88a is a protrusion provided on the first member 87a and protruding toward the center of the second member 87b. The second stopper portion 88b is provided on the second member 87b, and is a projection projecting outward (toward the first member 87a) from the center side of the second member 87b.

The first member 87a is fixed to, for example, the housing 84 of the channel switching portion 472 or the like. That is, the position of the first stopper portion 88a is fixed. On the other hand, the second member 87b is attached to the rotary shaft of the movable disk 82. As shown in FIG. That is, the second member 87b can rotate with respect to the first member 87a around the rotation axis RA as the movable disk 82 rotates. The movable disk 82 and the second stopper portion 88b integrally rotate in the plus direction D+ or the minus direction D− around the rotation axis RA.

As shown in FIG. 8, the second stopper portion 88b comes into contact with the first stopper portion 88a when rotated in the negative direction D−. As a result, the rotation of the second stopper portion 88b in the minus direction D−, that is, the rotation of the movable disk 82 in the minus direction D− is restricted. That is, the second stopper portion 88b and the movable disk 82 cannot rotate further in the negative direction D−. As shown in FIG. 8, the rotational position (rotational angle) of the movable disk 82 when the second stopper portion 88b abuts against the first stopper portion 88a and the rotation is restricted depends on the rotation of the movable disk 82 in the circumferential direction. It becomes the origin position.

In this example, the clockwise rotation direction is the minus direction D- and the counterclockwise rotation direction is the plus direction D+. good. Further, the stopper 88 is not limited to the above example, and may have any configuration that can regulate the rotation of the movable disk 82 and define the origin position of the rotation of the movable disk 82 .

That is, the opening 98 (first opening 98a) and the bidet supply hole 94 communicate with each other, and water is supplied to the bidet cleaning water spout 474c. The opening 98 (first opening 98a) communicates with the bottom supply hole 95, and water is supplied to the bottom washing spout 474a. The opening 98 (second opening 98b) communicates with the soft supply hole 96, and water is supplied to the soft wash spout 474b. As a result, the bidet washing spout 474c, the buttocks washing spout 474a, and the soft washing spout 474b spout water.

FIGS. 11(a) and 11(c) show a state in which the movable disk 82 and the second stopper portion 88b are further rotated in the positive direction D+ from the states of FIGS. 10(c) and 10(f). .

That is, the opening 98 (first opening 98a) communicates with the bottom supply hole 95, and water is supplied to the bottom washing spout 474a. As a result, the bottom washing spout 474a spouts water upward.

11(b) and 11(d) show a state in which the movable disk 82 and the second stopper portion 88b are further rotated in the positive direction D+ from the states of FIGS. 11(a) and 11(c). .
The state of FIG. 11(b) is a state in which the opening 98 (first opening 98a) and the soft supply hole 96 are overlapped. That is, the opening 98 (first opening 98a) communicates with the soft supply hole 96, and water is supplied to the soft wash spout 474b. As a result, the soft washing spout 474b spouts water upward.

As described above, the flow path switching section 472 can switch between the following first to fourth states by sliding and rotating the movable disk 82 relative to the fixed disk 80 in the circumferential direction. In the first state, for example, as shown in FIG. 9A, the opening 98 and the first supply hole 91 are overlapped and communicated to supply water to the first ejection port 479a. In the second state, for example, as shown in FIGS. 9B and 9C, the opening 98 and the second supply hole 92 are overlapped and communicated to supply water to the second ejection port 479b. In the third state, for example, as shown in FIGS. At least one of the bottom supply hole 95 and the soft supply hole 96) is overlapped and communicated with at least one of the plurality of private washing spouts (bottom washing spout 474a, soft washing spout 474b, bidet washing spout 474c). It is ready to supply water. In the fourth state, for example, as shown in FIG. 10A, the opening 98 and the bypass supply hole 93 are overlapped and communicated with each other to supply water to the bypass spout 478a.

The flow path switching unit 472 has an operation of supplying water to the first ejection port 479a and the second ejection port 479b before and/or after the user uses the toilet device (toilet bowl). Since water is ejected from the first ejection port 479a and the second ejection port 479b provided in the nozzle before and/or after use by the user, water can be ejected over a wide area.

More specifically, for example, when the seating detection sensor 404 detects that the user is seated on the toilet seat 200, the control unit 405 controls the flow path switching unit 472 to sequentially switch between the first state and the second state. switch. That is, before use by the user, an operation of ejecting water from the first ejection port 479a and an operation of ejecting water from the second ejection port 479b are performed. This allows water to adhere to a wider range of the bowl 801, making it difficult for the bowl 801 to become dirty.

Also, for example, when the seating detection sensor 404 detects that the user has left the toilet seat 200, the control unit 405 controls the flow path switching unit 472 to sequentially switch between the first state and the second state. That is, after use by the user, an operation of ejecting water from the first ejection port 479a and an operation of ejecting water from the second ejection port 479b are performed. As a result, a wider range of dirt on the bowl 801 can be removed.

Before and/or after use by the user, the first state may be switched to the second state, or conversely, the second state may be switched to the first state. Moreover, the trigger for starting water ejection before and/or after use by the user is not limited to the user's sitting down or leaving the seat. For example, before use by the user, the control unit 405 may start spouting water with the entry of the user into the toilet room, the operation of the operation unit 500, or the like as a trigger. After the user has used the toilet, the control unit 405 may start spraying water using the user's exit from the toilet room, the operation of the toilet flush button, or the like as a trigger.

On the other hand, when the nozzle ejects water over a wide area of the bowl, it may take a long time to eject the water. For example, when the nozzle is advanced before or after use by the user to spray water from the nozzle into the bowl, the water must be sprayed in a short period of time. When the next user sits down, there is a risk that the user will be splashed with water from the spout.

In contrast, in the embodiment, among the plurality of supply holes provided in fixed disk 80 , first supply hole 91 and second supply hole 92 are adjacent in the circumferential direction of fixed disk 80 . Thereby, a state (first state) in which water is ejected from the first ejection port 479a through the first supply hole 91 and a state (second state) in which water is ejected from the second ejection port 479b through the second supply hole 92 2 state), the angle at which the movable disk 82 is rotated can be reduced. Therefore, switching between the first state and the second state can be performed quickly. Therefore, it becomes possible to jet water over a wide range in a short time.

As described with reference to FIGS. 9A and 9D, the opening 98 (first opening 98a) communicates with the first supply hole 91 when the movable disk 82 is at the origin position. Also, the first supply hole 91 and the second supply hole are adjacent to each other without the stopper 88 interposed therebetween. That is, the first supply hole 91 and the second supply hole 92 are adjacent to each other in the direction of rotation (positive direction D+) opposite to the direction of rotation (minus direction D−) regulated by the stopper 88 . As a result, when switching between a state in which the opening 98 (first opening 98a) overlaps the first supply hole 91 and a state in which the opening 98 (first opening 98a) overlaps the second supply hole 92, the movable The rotation of disk 82 is not restricted by stopper 88 . Thus, according to the embodiment, the origin position can be reliably defined by the stopper 88, and the first supply hole 91 and the second supply hole 92 are adjacent to each other in the circumferential direction without the stopper 88 intervening. , makes it easier to spray water over a wider area in a shorter time.

The opening 98 (first opening 98a) may communicate with the second supply hole 92 when the movable disk 82 is at the origin position. For example, the positions of the first supply holes 91 and the second supply holes 92 in the circumferential direction may be exchanged.

9(a) to 9(c), 10(a) to 10(c), 11(a) and 11(b), for example, the first opening 98a The opening area is larger than the opening area of each of the through holes 91a to 96a of the fixed disk 80. As shown in FIG. The flow rate in each downstream can be adjusted by the opening area of each of the through holes 91a to 96a. Further, the flow rate in each downstream can be adjusted by the depth and width (radial length) of each of the groove channels 92b, 94b to 96b. The circumferential length of each of the groove channels 92b, 94b to 96b is longer than the circumferential length of the first opening 98a.

By providing the groove channel (one of 92b, 94b to 96b), it is possible to maintain a state in which a portion of the groove channel overlaps the first opening 98a while the movable disk 82 is rotating. In other words, it is possible to maintain a state in which the first opening 98a communicates with the groove channel during rotation of the movable disk. As a result, while rotating the movable disk 82, water can be ejected from the ejection port communicating with the groove channel. In this case, by adjusting the circumferential length of the groove channel, it is possible to adjust the length of time that the first opening 98a overlaps with the groove channel. That is, it is possible to adjust the length of time that water is ejected from the ejection port communicating with the first opening 98a through the groove channel.

For example, the second supply hole 92 has a groove channel 92b. As a result, while rotating the movable disk 82, the first opening 98a and the second supply hole 92 can be communicated with each other, and water can be ejected from the second ejection port 479b. By adjusting the length of the groove channel 92b, it is possible to adjust the length of time the water is ejected from the first ejection port 479a and the amount of water ejected from the second ejection port 479b without stopping the rotation of the movable disk 82 in the circumferential direction. You can adjust the ratio between

FIG. 12 is a flowchart illustrating the operation of the sanitary washing device according to the embodiment;
For example, a user is seated on the toilet seat 200 while using the toilet apparatus. At this time, the seating detection sensor 404 detects that the user is seated (step S101: No). When the user leaves the toilet seat 200 after using the toilet apparatus, the seating sensor detects no seating of the user (step S101: Yes).

Then, the control unit 405 controls the flow path switching unit 472 to be in the state (fourth state) shown in FIG. 10(a). As a result, water is ejected from the bypass ejection port 478a (step S102). At this time, the control unit 405 controls the nozzle driving unit 476 to move the nozzle 473 forward and backward. Specifically, the nozzle 473 is moved from the retracted position to the most advanced position, and then moved from the most advanced position to a predetermined position between the retracted position and the most advanced position. In this manner, water is ejected from the bypass ejection port 478a while moving the nozzle 473 forward and backward. As a result, the outer peripheral surface of the nozzle 473 is cleaned.

After that, the control unit 405 controls the flow path switching unit 472 to switch between the first state shown in FIG. 9(a) and the second state shown in FIGS. 9(b) and 9(c). switch sequentially. As a result, water is sequentially jetted toward the bowl 801 from the first jetting port 479a and the second jetting port 479b (step S103). In step S103, water may be ejected from the first ejection port 479a or the second ejection port 479b. In step S103, the position of the nozzle 473 is maintained at the predetermined position described above.

Next, the control unit 405 controls the flow path switching unit 472 to return the flow path switching unit 472 to the state shown in FIG. 10A (fourth state). As a result, water is ejected from the bypass ejection port 478a (step S104). At this time, the control unit 405 controls the nozzle drive unit 476 to move the nozzle 473 from the predetermined position described above to the storage position. In this manner, water is ejected from the bypass ejection port 478a while the nozzle 473 is retracted. This further cleans the outer peripheral surface of the nozzle 473 .

In the embodiment, when the movable disk 82 is rotated in the positive direction D+ from the origin position, the opening 98 is located next to the first supply hole 91 or the second supply hole 92 among the plurality of supply holes of the fixed disk. It communicates with the bypass supply hole 93 . In other words, after communicating with the first supply hole 91 or the second supply hole 92 , the opening 98 does not communicate with other supply holes (private washing supply holes) before communicating with the bypass supply hole 93 . More specifically, from the state in which the first opening 98a communicates with the first supply hole 91 or the second supply hole 92 as shown in FIGS. 9A to 9C, the movable disk 82 is moved in the positive direction D+. 10A, the second opening 98b communicates with the bypass supply hole 93 as shown in FIG. 10(a).

In this manner, the opening 98 of the movable disk 82 communicates with the bypass supply hole 93 next to the first and second supply holes 91 and 92, so that the first and second ejection ports 479a and 479b eject water; When switching between the state in which the bypass spout 478a spouts water, the opening 98 does not communicate with the private parts washing supply hole, and the private parts washing spout does not spout water. Therefore, as in the operation illustrated in FIG. 12, the first and second ejection ports 479a and 479b eject water and the bypass ejection port 478a ejects water while the nozzle 473 is advanced without being retracted. Even if the state and the state are switched, there is no leakage of water from the private parts washing spout. As a result, the nozzle 473 does not need to be retracted every time switching between the state in which the first and second jetting ports 479a and 479b jet water and the state in which the bypass jetting port 478a jets water. can suppress an increase in the number of driving times.
