Description

Aspects of the present invention generally relate to sanitary cleaning equipment.

Conventionally, it has been known to spout water into a bowl before use as a means for suppressing the adhesion and accumulation of dirt on the bowl of the toilet bowl. As an example of this, as in Patent Document 1, a nozzle for locally cleaning the human body of a sanitary cleaning device is provided with an outlet for ejecting water toward the bowl, and the nozzle is advanced from the casing to eject water from the ejection outlet into the bowl. There is something.

In this sanitary cleaning device, the ejection angle of the ejection port is set downward so that the user does not get wet when ejecting water while the user is seated on the toilet seat. However, if the ejection angle of the ejection port is set downward, it becomes difficult for water to adhere to the front side of the bowl.

As a means for solving this, for example, it is conceivable to eject water from the spout toward the front side of the bowl so that the user is not exposed to water. However, in this case, although it is easy for water to adhere to the front side of the bowl, it is difficult for water to adhere to the rear side of the bowl, and as a result, the range to which water ejected from the spout is adhered is narrow. turn into.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, similar components are designated by the same reference numerals and detailed description thereof will be omitted as appropriate.
FIG. 1 is a perspective view schematically showing a toilet device provided with the sanitary cleaning device according to the embodiment.
As shown in FIG. 1, the toilet device 900 includes a sitting toilet bowl (toilet bowl) 800 and a sanitary cleaning device 100 installed on the toilet bowl (toilet bowl) 800. The sanitary cleaning device 100 has a casing 400, a toilet seat 200, and a toilet lid 300. The toilet seat 200 and the toilet lid 300 are pivotally supported with respect to the casing 400 so as to be openable and closable. The toilet bowl 800 has a bowl 801. The toilet seat 200 has an opening 201.

In the description of the following embodiments, "upper", "lower", "front", "rear", "right side", and "left side" are used, but these directions are as shown in FIG. This is the direction seen from the user sitting on the toilet seat 200.

Inside the casing 400, there is a built-in local cleaning function unit that realizes local cleaning of the "buttocks" of the user sitting on the toilet seat 200. The local cleaning function unit includes a nozzle 473. The nozzle 473 can move forward and backward between the storage position housed in the casing 400 and the advance position advanced from the casing 400. The nozzle 473 advances in a linear trajectory toward the center of the bowl 801 located below the front of the casing 400, and retracts in a linear trajectory toward the inside of the casing 400 located above and behind the bowl 801. In the sanitary cleaning device 100 shown in FIG. 1, the nozzle 473 is in the advanced position.

The sanitary cleaning device 100 is provided with a seating detection sensor 404 (see FIG. 2) that detects the user's seating on the toilet seat 200. When the seating detection sensor 404 detects a user sitting on the toilet seat 200, when the user operates an operation unit 500 (see FIG. 2) such as a remote controller, the nozzle 473 is advanced to the advanced position or stored. It can be retracted to a position.

The nozzle 473 discharges water (washing water) toward the local part of the human body in a state of advancing from the casing 400 to wash the local part of the human body. The tip of the nozzle 473 is provided with a bottom cleaning spout 474a, a soft cleaning spout 474b, and a bidet cleaning spout 474c. The nozzle 473 can inject water from the buttocks washing spout 474a or the soft washing spout 474b provided at the tip thereof to wash the "buttocks" of the user sitting on the toilet seat 200. Alternatively, the nozzle 473 can inject water from the bidet washing spout 474c provided at the tip thereof to wash the female local part of the woman sitting on the toilet seat 200. The term "water" in the specification of the present application includes not only cold water but also heated hot water.

The mode for washing the "buttocks" includes, for example, "buttock washing" and "soft washing" in which the "buttocks washing" is gently washed with a softer stream of water than the "buttocks washing". The nozzle 473 can perform, for example, "buttock cleaning", "soft cleaning", and "bidet cleaning".

In the nozzle 473 shown in FIG. 1, the bidet cleaning spout 474c is provided on the tip side of the nozzle 473 from the soft cleaning spout 474b, and the soft cleaning spout 474b is more than the nozzle 473 than the tail cleaning spout 474a. However, the installation positions of the tail cleaning spout 474a, the soft cleaning spout 474b, and the bidet cleaning spout 474c are not limited to this. Further, the nozzle 473 shown in FIG. 1 is provided with three spouts. For example, the soft cleaning spout 474b may be omitted, or four or more spouts may be provided. Good.

FIG. 2 is a block diagram schematically showing a main configuration of the sanitary cleaning device according to the embodiment.
FIG. 2 also shows the main components of the water channel system and the electrical system.
As shown in FIG. 2, the sanitary cleaning device 100 has a water guiding unit 20. The water conveyance unit 20 has a pipeline 20a from a water supply source 10 such as a water supply or a water storage tank to a nozzle 473. The water guide unit 20 guides the water supplied from the water supply source 10 to the nozzle 473 through the pipeline 20a. The pipeline 20a is formed by, for example, each part such as the solenoid valve 431, the heat exchanger unit 440, and the flow path switching part 472 described below, and a plurality of pipes connecting these parts.

A solenoid valve 431 is provided on the upstream side of the water guiding portion 20. The solenoid valve 431 is a solenoid valve that can be opened and closed, and controls the supply of water based on a command from a control unit 405 provided inside the casing 400. In other words, the solenoid valve 431 opens and closes the pipeline 20a. By opening the solenoid 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 adjusts the pressure in the pipeline 20a to 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 the backflow of water to the upstream side of the check valve 433 when the pressure in the pipeline 20a drops.

A heat exchanger unit 440 (heating unit) 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 raise the temperature to, for example, a specified temperature. That is, the heat exchanger unit 440 produces hot water.

The heat exchanger unit 440 is an instant heating type (instantaneous type) heat exchanger using, for example, a ceramic heater. The instantaneous heating type heat exchanger can raise the temperature of water to a specified temperature in a short time as compared with the hot water storage heating type heat exchanger using the hot water storage tank. The heat exchanger unit 440 is not limited to the instantaneous heating type heat exchanger, and may be a hot water storage heating type heat exchanger. Further, the heating unit is not limited to the heat exchanger, and may be one using another heating method, for example, one using microwave heating.

The heat exchanger unit 440 is connected to the control unit 405. The control unit 405 raises the temperature of water to the temperature set by the operation unit 500 by controlling the heat exchanger unit 440 in response 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. The flow rate sensor 442 detects the flow rate of the water discharged from the heat exchanger unit 440. That is, the flow rate sensor 442 detects the flow rate of water flowing in the pipeline 20a. The flow rate sensor 442 is connected to the control unit 405. The flow rate sensor 442 inputs the flow rate detection result to the control unit 405.

An electrolytic cell unit 450 is provided downstream of the flow rate sensor 442. The electrolytic cell unit 450 produces a liquid (functional water) containing hypochlorous acid from tap water by electrolyzing the tap water flowing inside. The electrolytic cell unit 450 is connected to the control unit 405. The electrolytic cell unit 450 generates functional water based on the control by the control unit 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 vacuum breaker (VB) 452 is provided downstream of the electrolytic cell unit 450. The vacuum breaker 452 has, for example, a flow path for flowing water, an intake port for taking in air into the flow path, and a valve mechanism for opening and closing the intake port. The valve mechanism closes the intake port when water is flowing in the flow path, and opens the intake port when the flow of water is stopped to take in air into the flow path. That is, the vacuum breaker 452 takes in air into the pipeline 20a when there is no water flow in the water conveyance portion 20. For the valve mechanism, for example, a float valve is used.

The vacuum breaker 452 takes in air into the pipe line 20a as described above, thereby promoting drainage of a portion of the pipe line 20a downstream of the vacuum breaker 452, for example. The vacuum breaker 452 promotes drainage of the nozzle 473, for example. In this way, the vacuum breaker 452 drains the water in the nozzle 473 and takes in the air in the nozzle 473, so that, for example, the washing water in the nozzle 473 and the sewage collected in the bowl 801 can be collected from the water supply source 10 ( Suppresses backflow to the clean water) side.

A pressure modulation section 454 is provided downstream of the vacuum breaker 452. The pressure modulation unit 454 gives pulsation or acceleration to the flow of water in the pipeline 20a of the water guide unit 20, and causes the nozzle 473 to have a pulsating or accelerating water flow, a soft cleaning spout 474a, a soft cleaning spout 474b, a bidet cleaning spout 474c, and a nozzle cleaning unit. Pulsation is given to the water discharged from the water discharge part of 478. That is, the pressure modulation unit 454 fluctuates the flow state of the water flowing in the pipeline 20a. The pressure modulation unit 454 is connected to the control unit 405. The pressure modulation unit 454 fluctuates the flow state of water based on the control by the control unit 405. The pressure modulation unit 454 fluctuates the pressure of water in the pipeline 20a.

A flow rate adjusting unit 471 is provided downstream of the pressure modulation unit 454. The flow rate adjusting unit 471 adjusts the water force (flow rate). A flow path switching unit 472 is provided downstream of the flow rate adjusting unit 471. The flow path switching unit 472 opens / closes and switches the water supply to the nozzle 473 and the nozzle cleaning unit 478. The flow rate adjusting unit 471 and the flow path switching unit 472 may be provided as one unit. The flow rate adjusting unit 471 and the flow path switching unit 472 are connected to the control unit 405. The operation of the flow rate adjusting unit 471 and the flow path switching unit 472 is controlled by the control unit 405.

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

The nozzle cleaning unit 478 cleans the outer peripheral surface (body) of the nozzle 473 by injecting functional water or water from the water discharge unit, for example.

Further, downstream of the flow path switching unit 472 is a tail cleaning flow path 21 that supplies water supplied from the water supply source 10 via the water guide unit 20 and functional water generated in the electrolytic cell unit 450 to the nozzle 473. A soft cleaning flow path 22 and a bidet cleaning flow path 23 are provided. The buttocks cleaning flow path 21 connects the flow path switching unit 472 and the buttocks cleaning spout 474a. The soft cleaning flow path 22 connects the flow path switching portion 472 and the soft cleaning spout 474b. The bidet cleaning flow path 23 connects the flow path switching unit 472 and the bidet cleaning spout 474c.

Further, a surface cleaning flow path 24, a first bowl ejection flow path 25, and a second bowl ejection flow path 26 are provided downstream of the flow path switching portion 472. The surface cleaning flow path 24 guides the water supplied from the water supply source 10 via the water guiding unit 20 and the functional water generated in the electrolytic cell unit 450 to the water discharge unit of the nozzle cleaning unit 478. The first bowl ejection flow path 25 and the second bowl ejection flow path 26 use the water supplied from the water supply source 10 via the water guide section 20 and the functional water generated in the electrolytic cell unit 450 as the ejection port 479 of the nozzle 473 ( It leads to the first spout 479a and the second spout 479b) described later. The water or fuctional water supplied to the spout 479 is ejected from the spout 479 toward the bowl 801.

By controlling the flow path switching unit 472, the control unit 405 controls the buttocks cleaning flow path 21, the soft cleaning flow path 22, the bidet cleaning flow path 23, the surface cleaning flow path 24, the first bowl ejection flow path 25, and the first bowl. The opening and closing of each flow path of the 2-bowl ejection flow path 26 is switched. As described above, the flow path switching unit 472 is used for each of the plurality of water outlets such as the tail cleaning spout 474a, the soft cleaning spout 474b, the bidet cleaning spout 474c, the nozzle cleaning unit 478, and the spout 479. The state of communicating with the 20a and the state of not communicating with the pipeline 20a are switched.

The control unit 405 is supplied with electric power from the power supply circuit 401, and based on signals from the seating detection sensor 404, the flow rate sensor 442, the operation unit 500, and the like, the solenoid valve 431, the heat exchanger unit 440, and the electrolytic cell It controls the operations of the unit 450, the pressure modulation unit 454, the flow rate adjustment unit 471, the flow path switching unit 472, the nozzle drive unit 476, and the like. As a result, the control unit 405 controls the operation of the nozzle 473.

In addition, the casing 400 has various types such as a "warm air drying function", a "deodorizing unit", and an "indoor heating unit" that blow warm air toward the "buttocks" of the user sitting on the toilet seat 200 to dry them. A mechanism may be provided as appropriate. 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 cleaning function unit and other additional function units may not necessarily be provided.

FIG. 4 is a front view schematically showing a nozzle of the sanitary cleaning device according to the embodiment.
FIG. 5 is a cross-sectional view schematically showing the periphery of the nozzle of the sanitary cleaning device according to the embodiment.
FIG. 6 is a cross-sectional view schematically showing the periphery of the nozzle of the sanitary cleaning device according to the embodiment.
5 and 6 show the periphery of the nozzle 473 in the cross section taken along the line A1-A2 shown in FIG.

As shown in FIGS. 3 (a), 3 (b), 4, 5, and 6, 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. In other words, the nozzle cover 473b covers the nozzle head 473a.

The nozzle head 473a has a spout 474 (buttock wash spout 474a, soft wash spout 474b, and bidet wash spout 474c) that discharges water toward the human body, and a jet that ejects water toward the bowl 801. Outlets 479 (first spout 479a and second spout 479b) are provided. The nozzle head 473a is connected to the buttocks cleaning flow path 21, the soft cleaning flow path 22, the bidet cleaning flow path 23, the first bowl ejection flow path 25, and the second bowl ejection flow path 26.

The nozzle cover 473b has a hole 475a that communicates with a spout 474 (a tail wash spout 474a, a soft wash spout 474b, and a bidet wash spout 474c), and a spout 479 (first spout 479a and second spout 479a). A notch 475b that exposes the outlet 479b) is provided. As shown in FIG. 4, the notch portion 475b is provided below, for example, the central CL1 in the vertical direction of the front end portion 477 of the nozzle 473.

As described above, when the notch portion 475b that exposes the first ejection port 479a and the second ejection port 479b is provided below the central CL1 in the vertical direction of the front end portion 477 of the nozzle 473, when viewed from the user. The cutout portion 475b can be made inconspicuous. Thereby, the design property can be improved.

As shown in FIGS. 5 and 6, the sanitary cleaning device 100 includes a shielding plate 600. The shielding plate 600 is rotatably provided with respect to the casing 400. The shielding plate 600 is located in front of the nozzle 473 when the nozzle 473 is in the storage position. The shielding plate 600 is located above the nozzle 473 when the nozzle 473 is in the advanced position. The shielding plate 600 can be rotated by, for example, advancing and retreating the nozzle 473.

Hereinafter, the first spout 479a and the second spout 479b will be described in detail.
FIG. 5 shows a state in which water is ejected from the first ejection port 479a (that is, a forward cleaning operation described later). FIG. 6 shows a state in which water is ejected from the second ejection port 479b (that is, a rear cleaning operation described later).

The first spout 479a and the second spout 479b eject, for example, mist-like water. The particle size of the water ejected from the first spout 479a and the second spout 479b is based on, for example, the particle size of the water ejected from the buttocks wash spout 474a, the soft wash spout 474b, and the bidet wash spout 474c. Is also small. The particle size of the water ejected from the first ejection port 479a and the second ejection port 479b is, for example, about 400 μm.

As shown in FIG. 5, the first spout 479a opens toward the lower front side. The first spout 479a ejects water toward the lower front side. More specifically, the first ejection port 479a ejects water at the first ejection angle θ1 with respect to the horizontal plane HP. The first ejection angle θ1 is an angle formed by the first ejection direction D1 of the water ejected from the first ejection port 479a and the horizontal plane HP. The first ejection direction D1 can be represented by, for example, the center line of the ejection range R1 of the water ejected from the first ejection port 479a. The first ejection direction D1 may be represented by, for example, the normal line of the first ejection port 479a.

The first ejection angle θ1 is larger than, for example, the advance angle θ3 of the nozzle 473 with respect to the horizontal plane HP. The advance angle θ3 is an angle formed by the advance direction ED of the nozzle 473 and the horizontal plane HP. In other words, the first ejection port 479a ejects water toward the rear of the advance 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. 6, the second spout 479b is open toward the rear of the first spout 479a. The second spout 479b ejects water toward the rear of the first spout 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 an angle formed by the second ejection direction D2 of the water ejected from the second ejection port 479b and the horizontal plane HP. The second ejection direction D2 can be represented by, for example, the center line of the ejection range R2 of the water ejected from the second ejection port 479b. The second ejection direction D2 may be represented by, for example, the normal line of the second ejection port 479b.

The second ejection angle θ2 is larger than, for example, the advance angle θ3 of the nozzle 473 with respect to the horizontal plane HP. In other words, the second ejection port 479b ejects water toward the rear of the advance direction ED of the nozzle 473, for example. The second ejection angle θ2 is larger than the first ejection angle θ1. In other words, the second spout 479b ejects water toward the rear of the first spout 479a. The second ejection angle θ2 is, for example, 72 degrees or more and 90 degrees or less.

In this way, by providing two spouts 479 (first spout 479a and second spout 479b) that eject water in different directions in the front-rear direction, water can be adhered to a wider range of the bowl 801. it can. More specifically, the first spout 479a, which ejects water toward the front and lower directions, attaches water to the front side of the bowl 801 and ejects water toward the rear of the first spout 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 be adhered to the rear side of the bowl 801 where the water ejected from the first ejection port 479a is hard to adhere, and the water is adhered to a wider range of the bowl 801. Can be made to.

Further, as shown in FIG. 4, the second spout 479b is provided on the side of the first spout 479a. More specifically, the second spout 479b does not overlap the first spout 479a in the vertical direction. At least a part of the second spout 479b overlaps with the first spout 479a in the left-right direction, for example. Further, for example, the first ejection port 479a is located on one side (left side in this example) of the front end portion 477 of the nozzle 473 in the left-right direction, and the second ejection port 479b is located on the left-right side of the center CL2 in the left-right direction. Is also located on the other side (on the right side in this example).

The first ejection port 479a may be located on the right side of the center CL2 in the left-right direction of the front end portion 477 of the nozzle 473, and the second ejection port 479b may be located on the left side of the center CL2 in the left-right direction. In other words, the left-right position of the first spout 479a and the left-right position of the second spout 479b may be opposite.

In this way, when the second spout 479b is provided on the side of the first spout 479a, the direction in which the water of the first spout 479a is ejected and the direction in which the water of the second spout 479b is ejected are different. In addition, it is possible to prevent the water ejected from one spout 479 (for example, the second spout 479b) from hitting the other spout 479 (for example, the first spout 479a). As a result, it is possible to improve the degree of freedom in designing the direction in which the water of each spout 479 is ejected. Therefore, water can be ejected from the first spout 479a toward the front, and the water can be more easily adhered to the front side of the bowl 801.

Further, as shown in FIG. 4, the first spout 479a is located above, for example, the second spout 479b. More specifically, the center C1 of the first spout 479a is located above the center C2 of the second spout 479b.

By arranging the center C1 of the first spout 479a above the center C2 of the second spout 479b in this way, the water ejected from one spout 479 (for example, the second spout 479b) can be discharged. It is possible to more reliably suppress hitting the other ejection port 479 (for example, the first ejection port 479a).

Further, as shown in FIG. 4, the first spout 479a and the second spout 479b are provided, for example, at the front end portion 477 of the nozzle 473. More specifically, the first spout 479a and the second spout 479b are provided, for example, at the front end portion 477 of the nozzle 473, below the central CL1 in the vertical direction.

By providing the first spout 479a and the second spout 479b at the front end portion 477 of the nozzle 473 in this way, water can be ejected from the first spout 479a toward the front. This makes it easier for water to adhere to the front side of the bowl 801.

7 to 10 are cross-sectional views schematically showing a toilet device provided with the sanitary cleaning device according to the embodiment.
7 to 10 show a cross section taken along the line A1-A2 shown in FIG.
FIG. 7 shows the ejection range R2 when water is ejected from the second ejection port 479b in a state where the nozzle 473 is in the storage position. FIG. 8 shows the ejection range R2 when water is ejected from the second ejection port 479b in a state where the nozzle 473 is between the storage position and the predetermined position. FIG. 9 shows the ejection range R1 when water is ejected from the first ejection port 479a in a state where the nozzle 473 is in a predetermined position. FIG. 10 shows the ejection range R1 when water is ejected from the first ejection port 479a with the nozzle 473 in the advanced position.

The nozzle 473 is provided so as to be able to advance and retreat between the storage position shown in FIG. 7 and the advance position shown in FIG. More specifically, the nozzle 473 advances forward and downward from the storage position shown in FIG. 7, passes through the position shown in FIG. 8 and the position (predetermined position) shown in FIG. 9, and is shown in FIG. It is possible to advance to the advanced position. Further, the nozzle 473 retracts from the advanced position shown in FIG. 10 toward the rear and upper direction, passes through the position (predetermined position) shown in FIG. 9 and the position shown in FIG. 8, and reaches the storage position shown in FIG. It is possible to retreat.

In the embodiment, the control unit 405 performs pre-use cleaning before using the sanitary cleaning device 100. In the pre-use cleaning, the control unit 405 performs a front cleaning operation of ejecting water from the first ejection port 479a and a rear cleaning operation of ejecting water from the second ejection port 479b.

The forward cleaning operation is performed with at least the nozzle 473 in a predetermined position or in front of the predetermined position. As shown in FIG. 9, the predetermined position is a position between the storage position shown in FIG. 7 and the advance position shown in FIG.

By performing a forward cleaning operation in which water is ejected from the first ejection port 479a toward the front and lower sides while the nozzle 473 is in a predetermined position or in front of the predetermined position, it is possible to prevent water from splashing on the seated user. While doing so, water can be attached to the front side of the bowl 801.

The rear cleaning operation is performed with the nozzle 473 being at least behind the predetermined position. The rear cleaning operation may be performed with the nozzle 473 in the storage position as shown in FIG. 7, or the nozzle 473 is located between the storage position and the predetermined position as shown in FIG. It may be done in the state.

By performing the rear cleaning operation of ejecting water from the second ejection port 479b toward the rear of the first ejection port 479a while the nozzle 473 is behind the predetermined position, it is difficult for water to adhere in the front cleaning operation. Water can also be attached to the rear side of the bowl 801.

In this way, depending on the position of the nozzle 473, water is ejected from each of the two ejection ports (first ejection port 479a and second ejection port 479b) that eject water in different directions in the front-rear direction, thereby seating. Water can be adhered to a wider range of the bowl 801 from the spout 479 provided in the nozzle 473 while suppressing the water from splashing on the user inside.

As shown in FIGS. 9 and 10, the front end of the ejection range R1 when the nozzle 473 is in the advanced position is behind the front end of the ejection range R1 when the nozzle 473 is in the predetermined position. In this way, the position of the front end of the ejection range R1 becomes rearward as the nozzle 473 advances. In other words, the more the nozzle 473 advances, the more difficult it is for water to adhere to the front side of the bowl 801 when water is ejected from the first ejection port 479a. For this reason, it is preferable that the front cleaning operation is performed in a state where the nozzle 473 is in a predetermined position or in front of the predetermined position and behind the advance position.

On the other hand, if water is ejected from the first ejection port 479a in a state where the nozzle 473 is not sufficiently advanced, the position of the first ejection port 479a is high, so that the seated user is notified from the first ejection port 479a. There is a risk of splashing water. Therefore, as shown in FIG. 9, the front end portion 477 of the nozzle 473 is preferably located in front of the rear end 201a of the opening 201 of the toilet seat 200 when the nozzle 473 is in a predetermined position. In other words, the front cleaning operation is preferably performed in a state where the front end portion 477 of the nozzle 473 is located in front of the rear end 201a of the opening 201 of the toilet seat 200.

In this way, by performing the front cleaning operation in a state where the front end portion 477 of the nozzle 473 is located in front of the rear end 201a of the opening 201 of the toilet seat 200, the nozzle 473 is ejected from the first ejection port 479a to the seated user. It is possible to more reliably suppress the splashing of water.

Further, the front end portion 477 of the nozzle 473 is preferably located in front of the lower end of the shielding plate 600 when the nozzle 473 is in a predetermined position. In other words, the front cleaning operation is preferably performed in a state where the front end portion 477 of the nozzle 473 is located in front of the lower end of the shielding plate 600.

Further, when the advance amount of the nozzle 473 at the storage position is 0 and the advance amount of the nozzle 473 at the advance position is 100, the advance amount of the nozzle 473 at the predetermined position is preferably 35 or more and 95 or less, for example. More preferably, it is 50 or more and 70 or less.

FIG. 11 is a flowchart showing an example of the operation of the sanitary cleaning device according to the embodiment.
As shown in FIG. 11, in this example, when the seating detection sensor 404 changes from the state where the seating detection sensor 404 does not detect the seating to the state where the seating is detected (step S101: Yes), the control unit 405 advances the nozzle 473 to a predetermined position. (Step S102).

In this way, by performing the pre-use cleaning (front cleaning operation and rear cleaning operation) triggered by the user's seating, water can be attached to the bowl 801 immediately before the use of the sanitary cleaning device 100. As a result, it is possible to prevent the adhered water from drying out or falling off after a lapse of time after the water is adhered to the bowl 801. In particular, among the front cleaning operation and the rear cleaning operation, it is possible to prevent the adhered water from drying out or falling at a portion where water has adhered in the operation performed earlier.

The trigger for cleaning before use is not limited to the seating of the user. The control unit 405 may perform pre-use cleaning, for example, triggered by the user entering the toilet room or operating a button to open the toilet lid 300.

When the nozzle 473 is advanced to a predetermined position, the control unit 405 starts ejecting water (forward cleaning operation) from the first ejection port 479a (step S103). After the water is ejected from the first ejection port 479a for a predetermined time (for example, 6 seconds) (step S104: Yes), the control unit 405 stops the ejection of water from the first ejection port 479a (forward cleaning operation). (Step S105).

When the ejection of water from the first ejection port 479a is stopped, the control unit 405 retracts the nozzle 473 to the storage position (step S106).

When the nozzle 473 is retracted to the storage position, the control unit 405 starts ejecting water (rear cleaning operation) from the second ejection port 479b (step S107). After the water is ejected from the second ejection port 479b for a predetermined time (for example, 5 seconds) (step S108: Yes), the control unit 405 stops the ejection of water from the second ejection port 479b (rear cleaning operation). (Step S109).

After the start of step S103, the control unit 405 may advance the nozzle 473 forward from the predetermined position, or retract the nozzle 473 from a position ahead of the predetermined position to the predetermined position. That is, the control unit 405 ejects water from the first ejection port 479a while advancing the nozzle 473 forward of the predetermined position or retracting the nozzle 473 from the position ahead of the predetermined position to the predetermined position. May be done.

Step S105 may be performed after step S106. That is, the control unit 405 may stop the ejection of water from the first ejection port 479a after the nozzle 473 is retracted. Further, step S105 may be performed after the start of step S106 and before the completion of step S106. That is, the control unit 405 may stop the ejection of water from the first ejection port 479a while retracting the nozzle 473.

FIG. 12 is a flowchart showing another example of the operation of the sanitary cleaning device according to the embodiment.
As shown in FIG. 12, in this example, when the seating detection sensor 404 changes from the state where the seating detection sensor 404 does not detect the seating to the state where the seating is detected (step S201: Yes), the water from the second ejection port 479b (Backward cleaning operation) is started (step S202).

After the water is ejected from the second ejection port 479b for a predetermined time (for example, 6 seconds) (step S203: Yes), the control unit 405 stops the ejection of water from the second ejection port 479b (rear cleaning operation). (Step S204). When the ejection of water from the second ejection port 479b is stopped, the control unit 405 advances the nozzle 473 to a predetermined position (step S205).

When the nozzle 473 is advanced to a predetermined position, the control unit 405 starts ejecting water (forward cleaning operation) from the first ejection port 479a (step S206). After the water is ejected from the first ejection port 479a for a predetermined time (for example, 5 seconds) (step S207: Yes), the control unit 405 stops the ejection of water from the first ejection port 479a (forward cleaning operation). (Step S208).

When the ejection of water from the first ejection port 479a is stopped, the control unit 405 retracts the nozzle 473 to the storage position (step S209).

After the start of step S206, the control unit 405 may advance the nozzle 473 forward from the predetermined position, or retract the nozzle 473 from a position ahead of the predetermined position to the predetermined position. That is, the control unit 405 ejects water from the first ejection port 479a while advancing the nozzle 473 forward of the predetermined position or retracting the nozzle 473 from the position ahead of the predetermined position to the predetermined position. May be done.

Step S208 may be performed after step S209. That is, the control unit 405 may stop the ejection of water from the first ejection port 479a after the nozzle 473 is retracted. Further, step S208 may be performed after the start of step S209 and before the completion of step S209. That is, the control unit 405 may stop the ejection of water from the first ejection port 479a while retracting the nozzle 473.

FIG. 13 is a flowchart showing another example of the operation of the sanitary cleaning device according to the embodiment.
As shown in FIG. 13, in this example, when the seating detection sensor 404 changes from the state where the seating detection sensor 404 does not detect the seating to the state where the seating is detected (step S301: Yes), the water from the second ejection port 479b (Backward cleaning operation) is started (step S302).

When the ejection of water from the second ejection port 479b is started, the control unit 405 advances the nozzle 473 to a predetermined position with the water ejected from the second ejection port 479b (step S303). That is, the control unit 405 performs the rear cleaning operation while advancing the nozzle 473 to a predetermined position.

In this way, by performing the rear cleaning operation while advancing the nozzle 473 before the front cleaning operation, water can be adhered to a wider range of the bowl 801 in a shorter time.

When the nozzle 473 is advanced to a predetermined position, the control unit 405 stops the ejection of water (rear cleaning operation) from the second ejection port 479b (step S304) and ejects water from the first ejection port 479a (step S304). The forward cleaning operation) is started (step S305).

After the water is ejected from the first ejection port 479a for a predetermined time (for example, 5 seconds) (step S306: Yes), the control unit 405 stops the ejection of water from the first ejection port 479a (forward cleaning operation). (Step S307), and the water ejection (rear cleaning operation) from the second ejection port 479b is started (step S308).

When the ejection of water from the second ejection port 479b is started, the control unit 405 retracts the nozzle 473 to the storage position in a state where the water is ejected from the second ejection port 479b (step S309). That is, the control unit 405 performs the rear cleaning operation while retracting the nozzle 473 to the storage position.

By performing the rear cleaning operation while retracting the nozzle 473 in this way, it is possible to prevent the lump of residual water in the nozzle 473 from falling into the bowl 801. As a result, it is possible to prevent the water adhering to the bowl 801 from flowing due to the lump of residual water in the nozzle 473 during the rear cleaning operation.

When the nozzle 473 is retracted to the storage position, the control unit 405 stops the water ejection (rear cleaning operation) from the second ejection port 479b (step S310).

Step S302 may be performed after the start of step S303 and before the completion of step S303. That is, the control unit 405 may start ejecting water from the second ejection port 479b while advancing the nozzle 473.

Further, steps S304 and S305 may be performed after the start of step S303 and before the completion of step S303. That is, the control unit 405 may stop the ejection of water from the second ejection port 479b while advancing the nozzle 473, or the control unit 405 may advance the nozzle 473 while ejecting water from the first ejection port 479a. You may start.

Step S310 may be performed after the start of step S309 and before the completion of step S309. That is, the control unit 405 may stop the ejection of water from the second ejection port 479b while retracting the nozzle 473.

Further, steps S307 and S308 may be performed after the start of step S309 and before the completion of step S309. That is, the control unit 405 may stop the ejection of water from the first ejection port 479a while retracting the nozzle 473, or may stop the ejection of water from the first ejection port 479a while advancing the nozzle 473 while ejecting water from the second ejection port 479b. You may start.

Further, step S310 may be performed after a predetermined time (for example, 5 seconds) has passed after the completion of step S309. That is, the control unit 405 may continue to eject water from the second ejection port 479b for a predetermined time (for example, 5 seconds) with the nozzle 473 retracted to the storage position.

In the embodiment, the rear cleaning operation may be performed at least before the front cleaning operation and after the front cleaning operation. That is, when steps S302 and S304 are performed, steps S308 and S310 are performed as needed and can be omitted. Similarly, when steps S308 and S310 are performed, steps S302 and S304 are performed as needed and can be omitted.

Further, in the embodiment, the control unit 405 may perform post-use cleaning after using the sanitary cleaning device 100. More specifically, the control unit 405 may perform cleaning after use, for example, when the seating detection sensor 404 changes from the state where the seating detection sensor 404 detects the seating to the state where the seating is not detected. The water ejected from the ejection port 479 in the cleaning after use may be the functional water generated in the electrolytic cell unit 450.

The trigger for cleaning after use is not limited to the user leaving the seat. The control unit 405 may perform cleaning after use, triggered by, for example, leaving the user's toilet room or operating a button for cleaning the toilet bowl. Post-use cleaning can be performed in the same flow as the flow shown in FIGS. 11 to 13 above.

As described above, according to the embodiment, it is possible to attach water to a wider range of the bowl 801 from the ejection port 479 provided in the nozzle 473 while suppressing the water from splashing on the seated user. The sanitary cleaning device 100 can be provided.
