A toilet cleaning device provided with two nozzles for jetting cleaning water to a part of a human body, comprising: a driving part which respectively drives the two nozzles to advance and retreat; a supply unit configured to supply washing water to one or both of the two nozzles; and a control part capable of controlling the driving part and the supply part so that both nozzles are extended to spray the washing water from both nozzles toward the human body part.

Description

Toilet cleaning device

Technical Field

The invention relates to a toilet cleaning device.

Background

Conventionally, as such a toilet cleaning device, a configuration has been proposed which includes a nozzle for locally discharging cleaning water toward a human body, a driving unit for moving the nozzle forward and backward, and a supply unit for supplying cleaning water to the nozzle. For example, the toilet cleaning device of patent document 1 includes, as a driving unit, a front-rear moving unit that moves a nozzle in a front-rear direction and a left-right moving unit that moves the nozzle in a left-right direction. When the washing water is discharged, the forward-and-backward moving unit and the leftward-and-rightward moving unit are driven to cause the nozzle to trace a predetermined trajectory, thereby discharging the washing water along the predetermined trajectory.

In the toilet cleaning device of patent document 2, an inflow chamber into which cleaning water flows is formed in the nozzle, and a water discharge body is provided, the water discharge body being swingably assembled in an inclined posture in the inflow chamber and having a water discharge port exposed to the outside. Then, by supplying the cleaning water to the inflow chamber in the tangential direction, a swirling flow is caused along the inner wall surface of the inflow chamber, and the discharged water is swung by a force generated by a difference in flow velocity in the chamber. Thereby, the washing water guided to the water discharge port is discharged in a conical shape with the swing position as a vertex.

Patent document 2: japanese patent No. 3518542

The toilet seat cleaning device described above enlarges the cleaning range and provides a new cleaning feeling, but since one nozzle is used, the larger the cleaning range, the weaker the momentum of the cleaning water becomes, and the cleaning feeling may be reduced. Therefore, in order to avoid such a situation, it is also conceivable to modify the conventional device structure, but a large modification is necessary, which complicates the device structure and deteriorates reliability such as durability.

Disclosure of Invention

The main object of the present invention is to provide a new cleaning feeling appropriately without complicating the structure of the conventional apparatus.

In order to achieve the above-described main object, the present invention adopts the following means.

The toilet cleaning device of the present invention is provided with two nozzles for jetting cleaning water to a human body part, wherein the toilet cleaning device is characterized by comprising:

a driving unit that moves the two nozzles forward and backward;

a supply unit configured to supply washing water to one or both of the two nozzles;

and a control part capable of controlling the driving part and the supply part so that both the nozzles are extended to spray the washing water from the nozzles toward the human body part.

The toilet cleaning device of the present invention is provided with two nozzles for jetting cleaning water toward a part of a human body, wherein the two nozzles can be controlled to be extended to jet the cleaning water toward the part of the human body from the two nozzles. Therefore, the cleaning range can be expanded and the cleaning feeling can be improved without adding a new drive device and a water discharge device to the nozzle. Therefore, a new feeling of cleaning can be appropriately given without complicating the structure of the conventional apparatus.

In the toilet cleaning apparatus according to the present invention, the control unit may control the drive unit and the supply unit such that one of the two nozzles is fixed at a predetermined cleaning position to discharge the cleaning water and the other nozzle is swung in a forward and backward direction to discharge the cleaning water. In this way, since the washing water from the fixed nozzle and the washing water from the swinging nozzle are simultaneously discharged to the human body part, a new washing feeling can be given.

In the toilet cleaning apparatus according to the present invention, the control unit may control the drive unit and the supply unit so that the two nozzles discharge the cleaning water while oscillating in different directions. In this way, since the two nozzles are swung together and simultaneously discharge the washing water to the human body part, a new washing feeling can be given.

In the toilet cleaning apparatus according to the present invention, the control unit may control the drive unit and the supply unit so that the two nozzles are fixed at predetermined cleaning positions, respectively, to alternately discharge the cleaning water. In this way, since the washing water from the two nozzles is alternately discharged to the local part of the human body, a new washing feeling can be given.

In the toilet cleaning apparatus according to the present invention, the two nozzles and the supply unit may be configured such that at least one of a water amount, a water temperature, a cleaning intensity, and a cleaning range of the cleaning water ejected from the two nozzles is different. In this way, since the change of the washing by the washing water discharged from the two nozzles can be increased, the washing feeling can be further improved.

Detailed Description

Next, a mode for carrying out the present invention will be described.

Fig. 1 is an external perspective view of a toilet seat cleaning device 10, and fig. 2 is a configuration diagram showing an overview of the configuration of the toilet seat cleaning device 10. As shown in fig. 1, a toilet cleaning device 10 is attached to the upper surface of a toilet 1, and includes: a toilet seat device main body 12, a toilet seat 14 supported to be openable and closable with respect to the toilet seat device main body 12, a toilet lid 16 supported to be openable and closable with respect to the toilet seat device main body 12, and an operation panel 18 on which various operations can be performed by a user.

As shown in fig. 2, the toilet seat apparatus main body 12 includes: a water supply path 20 for supplying washing water, a nozzle unit 30 for locally spraying the supplied washing water to a human body, and a control device 50 for controlling the whole device.

The water supply path 20 is provided with: a pressure reducing valve 24 for reducing the pressure of the washing water supplied from the water supply source through the water stop solenoid valve 22 to a predetermined pressure, a heat exchange unit 26 for heating the washing water, a water temperature sensor 28 for detecting the temperature of the washing water, and a flow rate sensor 29 for detecting the flow rate of the washing water. In the present embodiment, the heat exchange unit 26 incorporates a ceramic heater or the like having a rated output of, for example, about 1200W, and is configured as an instantaneous heat exchange unit capable of instantaneously heating the washing water.

The nozzle unit 30 includes: a pulsating pump 32 that adjusts the intensity of the cleaning, a vacuum breaker 34, a switching valve 36, a first nozzle 40, and a second nozzle 42. The nozzle unit 30 further includes: a first nozzle driving unit 44 for moving the first nozzle 40 forward and backward by a motor 44a and a gear mechanism not shown, and a second nozzle driving unit 46 for moving the second nozzle 42 forward and backward by a motor 46a and a gear mechanism not shown. The first nozzle 40 and the second nozzle 42 are movable forward and backward between a storage position stored in a nozzle case, not shown, and a cleaning position projected from the nozzle case and from which cleaning water is discharged, by a first nozzle driving unit 44 and a second nozzle driving unit 46, respectively.

Fig. 3 is a structural view showing

tip members

41 and 43 of the respective nozzles. As shown in the drawing, the tip member 41 of the first nozzle 40 is formed with a straight ejection port 41a that ejects washing water having high straightness from a relatively large one opening, and a diffusion ejection port 41b that ejects washing water from a plurality of relatively small openings to a wide washing range. In the present embodiment, the tip member 43 of the second nozzle is also formed with a straight discharge port 43a and a diffusion discharge port 43b, similarly to the tip member 41.

The switching valve 36 is configured as, for example, a rotary disk valve, and switches from which of the plurality of outlet ports the washing water supplied from the pulsation pump 32 through the inlet port flows out. The respective outflow ports of the switching valve 36 are connected to the straight discharge port 41a and the diffusion discharge port 41b of the first nozzle 40 and the straight discharge port 43a and the diffusion discharge port 43b of the second nozzle 42 via the

supply hoses

36a, 36b, 36c, and 36d, respectively. Although not shown, the switching valve 36 includes a disk-shaped valve body having an inflow path for the cleaning water from the pulsation pump 32 and a plurality of outflow paths connected to the respective outflow ports, and is configured to switch a communication state between the inflow path and the outflow paths by rotating the valve body by driving a motor, not shown. Therefore, the switching valve 36 can supply the cleaning water to any of the straight ejection port 41a, the diffusion ejection port 41b, the straight ejection port 43a, and the diffusion ejection port 43 b. The switching valve 36 is configured to be in a communication state in which the inflow path and the plurality of outflow paths are simultaneously communicated with each other, so that the washing water can be simultaneously supplied to the plurality of discharge ports while simultaneously flowing out the washing water from the two discharge ports. For example, the switching valve 36 is configured to be switchable between a communication state in which the cleaning water is simultaneously supplied to the straight ejection port 41a and the straight ejection port 43a, a communication state in which the cleaning water is simultaneously supplied to the straight ejection port 41a and the diffusion ejection port 43b, and a communication state in which the cleaning water is simultaneously supplied to the diffusion ejection port 41b and the diffusion ejection port 43 b. Further, a configuration in which the switching valve 36 can simultaneously supply the cleaning water to the two paths is well known as described in japanese patent application laid-open No. 2008-240403, and therefore, a detailed description thereof is omitted.

The operation panel 18 is provided with: a buttocks washing switch 18a for instructing buttocks washing, a pudendum washing switch 18b for instructing pudendum washing, a lock/move switch 18c for instructing lock/move washing, a cross switch 18d for instructing cross washing, a side alternate switch 18e for instructing side alternate washing, a washing stop switch 18f for instructing stop of washing, a temperature adjusting switch 18g for adjusting the temperature of washing water, a water potential adjusting switch 18h for adjusting the potential of washing water, and the like. The lock/move washing, the cross washing, and the side alternate washing are washing methods in which both the first nozzle 40 and the second nozzle 42 are moved to the washing position and the washing water is discharged, and will be described in detail later.

The control device 50 is a microcomputer including a CPU52, and includes a ROM54, a RAM56, a timer 58, and input/output ports in addition to the CPU 52. An operation signal from the operation panel 18, a seating signal from a seating sensor 19 that detects that a user is seated on the toilet seat 14, a water temperature detected by the water temperature sensor 28, a flow rate detected by the flow rate sensor 29, and the like are input to the controller 50 via the input port. A drive signal to the water stop solenoid valve 22, a control signal to the heat exchange unit 26, a drive signal to the pulsation pump 32, a drive signal to the switching valve 36, a drive signal to the motor 44a of the first nozzle drive unit 44, a drive signal to the motor 46a of the second nozzle drive unit 46, and the like are output from the control device 50 via the output port.

Next, the operation of the toilet cleaning device 10 according to the embodiment configured as above, particularly the operation in the case of cleaning a human body private part, will be described. Fig. 4 is a flowchart showing an example of a cleaning control routine executed by the CPU52 of the control device 50. This routine is executed when the seating of the user on the toilet seat 14 is detected based on the seating signal from the seating sensor 19.

First, the CPU52 of the control device 50 waits for an instruction to start washing of the human body part (S100). In S100, the CPU52 determines that the washing start is instructed when the user operates either the hip wash switch 18a or the pudendum wash switch 18 b. When the CPU52 determines that the washing start is instructed, it further determines whether normal washing is instructed (S110), whether lock/shift washing is instructed (S120), whether cross washing is instructed (S130), and whether side alternate washing is instructed (S140). Here, after determining in S100 that the washing start is instructed, the CPU52 determines in S110 that the normal washing is instructed if none of the lock/move switch 18c, the cross switch 18d, and the side alternation switch 18e is operated. When it is determined at S110 that the normal washing is instructed, the CPU52 fixes one of the two nozzles, i.e., the first nozzle 40 and the second nozzle 42, at a predetermined washing position for washing the buttocks or a predetermined washing position for washing the private parts (hereinafter simply referred to as "washing position") and discharges washing water, thereby performing the normal washing (S150). Further, if one of the nozzles does not enter the cleaning position, the CPU52 controls the corresponding nozzle driving unit to move the one of the nozzles to the cleaning position. The CPU52 controls the pulsation pump 32 and the switching valve 36 so that one nozzle ejects the washing water. The CPU52 performs local cleaning using the straight discharge port 41a of the first nozzle 40 in the case of hip cleaning, and performs normal cleaning using the spread discharge port 43b of the second nozzle 42 in the case of pudendum cleaning, for example. However, in the present embodiment, since the

tip members

41 and 43 of the first nozzle 40 and the second nozzle 42 are configured similarly, any nozzle may be used in S150.

When the CPU52 determines in S120 that lock/move washing has been instructed in accordance with the operation of the lock/move switch 18c, it controls the

nozzle driving units

44 and 46, the pulsation pump 32, and the switching valve 36 to simultaneously discharge washing water from both the first nozzle 40 and the second nozzle 42 while fixing one of the nozzles at the washing position and swinging the other nozzle in the forward and backward directions about the washing position (S160). Further, if the two nozzles do not enter the cleaning position, the CPU52 controls the respective

nozzle driving parts

44, 46 to move the two nozzles to the cleaning position, and then controls the pulsation pump 32, the switching valve 36 to cause the two nozzles to eject the cleaning water. The same applies to S170 and S180.

When it is determined in S130 that cross washing has been instructed by the operation of the cross switch 18d, the CPU52 controls the

nozzle drivers

44 and 46, the pulsation pump 32, and the switching valve 36 to simultaneously discharge washing water from the first nozzle 40 and the second nozzle 42 while swinging the nozzles in the forward and backward directions about the washing position (S170). When it is determined in S140 that the side alternate washing has been instructed by the operation of the side alternate switch 18e, the CPU52 fixes the first nozzle 40 and the second nozzle 42 at the washing position, controls the pulsation pump 32 and the switching valve 36 to alternately discharge the washing water from both the nozzles, and performs the side alternate washing (S180).

When the CPU52 determines that any one of the cleaning operations in S150 to S180 has been performed or that any one of S110 to S140 has not been performed, it determines whether or not various adjustment instructions have been performed (S190). The determination at S190 is made based on whether or not the temperature adjustment switch 18g, the water potential adjustment switch 18h, and the like are operated, for example. If it is determined that the adjustment instruction has been issued, the CPU52 controls the heat exchange unit 26 and the pulsation pump 32 to adjust the temperature, the potential head, and the like of the washing water based on the adjustment instruction (S200), and if it is determined that the adjustment instruction has not been issued, S200 is skipped. The processing in S190 and S200 is not limited to this timing, and may be performed at any timing in the cleaning control program. Next, the CPU52 determines whether or not the stop of washing has been instructed by the operation of the washing stop switch 18f (S210), and if it is determined that the stop of washing has not been instructed, the process returns to S110 to repeat the process. On the other hand, if the CPU52 determines that the stop of washing has been instructed, the CPU stops the ejection of the washing water from the first and

second nozzles

40 and 42 and moves the first and

second nozzles

40 and 42 located at the washing position to the storage position, thereby ending the partial washing (S220), and ends the washing control routine.

Here, fig. 5 is an explanatory diagram showing an example of a washing operation image in the hip washing mode, and fig. 6 is an explanatory diagram showing an example of a washing operation image in the private part washing mode. Fig. 5 and 6 show cleaning operation images of lock/shift cleaning, cross cleaning, and side alternate cleaning other than normal cleaning. The washing range of the washing water discharged from the first nozzle 40 is indicated by a dotted line, and the washing range of the washing water discharged from the second nozzle 42 is indicated by a dashed-dotted line. The black dots indicate the center position of the cleaning range of the cleaning water discharged from the first nozzle 40 or the second nozzle 42 fixed at a predetermined cleaning position.

As shown in fig. 5, the locking/moving washing of the hip washing is performed by either one of the locking/moving 1 and 2. The lock/move 1 simultaneously discharges the cleaning water from the straight discharge port 41a and the diffusion discharge port 43b while fixing the first nozzle 40 and swinging the second nozzle 42. In lock/move 1, relatively strong washing water is ejected from straight ejection port 41a to a relatively narrow fixed washing range at any time from time t10 to t18, and relatively weak washing water is ejected from diffusion ejection port 43b to a relatively wide washing range moving at time t10 to t 18. Further, the lock/move 2 simultaneously discharges the cleaning water from the straight discharge port 41a and the diffusion discharge port 43b while fixing the second nozzle 42 and swinging the first nozzle 40. In lock/move 2, relatively strong washing water is ejected from straight ejection port 41a to a relatively narrow washing range that moves from time t20 to t28, and relatively weak washing water is ejected from diffusion ejection port 43b to a relatively wide fixed washing range from any of times t20 to t 28.

As shown in fig. 6, since the locking/moving washing for the private part washing is performed in accordance with either one of the locking/moving 1 and the moving 2, as in the locking/moving washing for the hip part washing, the detailed description thereof will be omitted. By such lock-and-move washing, the user can be given a new washing feeling of performing the partial washing simultaneously with the washing water discharged to the fixed washing range and the washing water discharged to the swing washing range. Further, since one cleaning range is fixed and the other cleaning range is swung (moved), a new cleaning feeling that cannot be obtained in cleaning in which two kinds of cleaning water are ejected from one nozzle can be given. Further, since the user can select the lock/move 1 for fixing the strong washing water discharged to the relatively narrow washing range and swinging the weak washing water discharged to the relatively wide washing range and the lock/move 2 for fixing the weak washing water discharged to the relatively wide washing range and swinging the strong washing water discharged to the relatively narrow washing range, the user can appropriately respond to the washing feeling preferred by the user. After the washing is started by the operation of the hip-washing switch 18a or after the washing is started by the operation of the pudendum-washing switch 18b, the washing mode is switched in the order of lock/shift 1, lock/shift 2, and lock/shift release (normal hip-washing, pudendum-washing) every time the lock/shift switch 18c is operated. In the following cross washing and side alternate washing, the washing mode is switched every time the switch is operated in the same manner.

As shown in fig. 5, the cross washing of the hip washing is performed in accordance with either one of the crosses 1 and 2. In intersections 1 and 2, the first nozzle 40 and the second nozzle 42 are oscillated about the cleaning position (oscillated in opposite directions) to eject the cleaning water from the straight ejection port 41a and the straight ejection port 43a simultaneously. Therefore, in the intersection 1, the movement is repeated so that the cleaning range of the cleaning water ejected from the straight ejection port 41a and the cleaning range of the cleaning water ejected from the straight ejection port 43a are brought from the initial state (time t30) in which they overlap each other, to the state (time t31 to t34) in which they approach each other again after being separated from each other, and to the state (time t35 to t38) in which they approach each other again after being separated from each other and overlap each other. In the cross washing, the washing ranges of the first nozzles 40 are shown in a state where the washing ranges overlap with each other. In intersection 2, the time when the cleaning ranges of the two nozzles overlap differs from intersection 1. The cleaning ranges overlap at time t34 in intersection 1, while the cleaning ranges overlap for a relatively long time at time t44 to t46 in intersection 2. Thus, in the intersection 1, a wide range is uniformly washed with relatively strong washing water, whereas in the intersection 2, the center position is intensively washed while the wide range is washed with relatively strong washing water. In addition, the moving pattern of the cleaning range can be changed to give different cleaning feeling.

As shown in fig. 6, the cross washing for private part washing is performed in accordance with either one of the intersections 3 and 4. In intersections 3 and 4, the first nozzle 40 and the second nozzle 42 are oscillated about the cleaning position to be different from each other, and simultaneously, the cleaning water is discharged from the diffusion discharge port 41b and the diffusion discharge port 43 b. The movement pattern of the cleaning range at each time of intersections 3 and 4 is the same as the movement pattern of the cleaning range at each time of intersections 1 and 2. Thus, in the intersection 3, a wide range is uniformly washed with the relatively weak washing water, whereas in the intersection 4, the center position is intensively washed while the wide range is washed with the relatively weak washing water. In addition, the moving pattern of the cleaning range can be changed to give different cleaning feeling.

As shown in fig. 5, the alternate side washing of the hip washing is performed by alternate side 1. In the side alternation 1, the first nozzle 40 and the second nozzle 42 are fixed at the cleaning position, and the cleaning water is alternately discharged from the straight discharge port 41a and the straight discharge port 43 a. Fig. 5 shows a case where the washing water is ejected from the straight ejection port 41a at times t50, t52, t54, t56, and t58, and the washing water is ejected from the straight ejection port 43a at times t51, t53, t55, and t 57.

As shown in fig. 6, the private parts are washed by the side alternation 2. In the side alternation 2, the first nozzle 40 and the second nozzle 42 are fixed at the cleaning position, and the cleaning water is alternately discharged from the diffusion discharge port 41b and the diffusion discharge port 43 b. Fig. 6 shows a case where the cleaning water is ejected from the diffusion ejection port 41b at times t50, t52, t54, t56, and t58, and the cleaning water is ejected from the diffusion ejection port 43b at times t51, t53, t55, and t 57. By such side surface alternate washing, a new washing feeling can be given to the user that the user performs partial washing with the washing water alternately ejected from the left and right nozzles.

In the toilet cleaning device 10 according to the present embodiment described above, both the first nozzle 40 and the second nozzle 42 are moved to the cleaning position, and the cleaning water is ejected from both the nozzles toward the private parts of the human body. Therefore, a new feeling of washing can be appropriately given without complicating the structure of the conventional apparatus. Further, since the cleaning water can be ejected from the two nozzles in different cleaning ranges or the cleaning ranges can be moved, the cleaning effect can be improved. In addition, the present invention provides an effect of alleviating pain felt by a user when the user touches the washing water and improving massage, as compared with a case where local washing is performed only by strong washing water from one nozzle.

The toilet cleaning apparatus 10 performs lock-and-move cleaning in which one of the first nozzle 40 and the second nozzle 42 is fixed at a predetermined cleaning position to discharge cleaning water, and the other nozzle is swung in the forward and backward directions about the cleaning position to discharge cleaning water. Therefore, a new washing feeling can be given to the user, in which the user performs the partial washing with the washing water simultaneously ejected from the fixed nozzle and the swinging nozzle.

The toilet cleaning apparatus 10 performs the cross cleaning in which the first nozzle 40 and the second nozzle 42 are swung around the cleaning position in the forward and backward directions so as to eject the cleaning water. Therefore, a new washing feeling can be given to the user that the user can wash the local area with the washing water ejected simultaneously while swinging the two nozzles together.

The toilet seat cleaning apparatus 10 performs side-surface alternate cleaning in which the first nozzle 40 and the second nozzle 42 are fixed at predetermined cleaning positions, respectively, and cleaning water is alternately discharged. Therefore, a new feeling of washing can be given to the user, in which the user performs partial washing with the washing water alternately ejected from the left and right nozzles.

In the toilet cleaning device 10, the

straight discharge ports

41a and 43a and the diffuse

discharge ports

41b and 43b having different cleaning ranges are formed in the first nozzle 40 and the second nozzle 42, and therefore, the cleaning feeling can be further improved by increasing the change in cleaning by the cleaning water discharged from the two nozzles.

In the embodiment, the locking/moving washing for the hip washing and the locking/moving washing for the pudendum washing are the same washing mode (locking/moving 1, 2), but the present invention is not limited thereto, and may be different washing modes. For example, the locking/moving washing for the hip washing may be performed according to the locking/moving 1, and the locking/moving washing for the private part washing may be performed according to the locking/moving 2. Alternatively, the washing water from the straight discharge port 41a of the fixed first nozzle 40 and the washing water from the straight discharge port 43a of the swinging second nozzle 42 may be simultaneously discharged in the lock/move washing of the hip washing, and the washing water from the diffusion discharge port 41b of the fixed first nozzle 40 and the washing water from the diffusion discharge port 43b of the swinging second nozzle 42 may be simultaneously discharged in the lock/move washing of the pudendum washing. The lock/move washing in fig. 5 and 6 is an example, and any washing mode may be used as long as washing water is simultaneously discharged while one nozzle is fixed and the other nozzle is swung.

In the embodiment, the cross washing of the hip washing and the cross washing of the pudendum washing are different washing modes, but the present invention is not limited thereto, and a common washing mode may be provided. The cross washing in fig. 5 and 6 is an example, and any washing pattern may be used as long as the two nozzles are oscillated differently to eject washing water simultaneously.

In the embodiment, the alternate side washing for hip washing and the alternate side washing for pudendum washing are different washing modes, but the present invention is not limited thereto, and a common washing mode may be provided. The side alternate washing in fig. 5 and 6 is an example, and any washing pattern may be used as long as two nozzles are fixed and washing water is alternately discharged.

In the embodiment, three types of cleaning, that is, lock/shift cleaning, cross cleaning, and side alternate cleaning, can be performed as the partial cleaning using two nozzles at the same time, but the invention is not limited thereto, and either one or two types of cleaning may be performed.

In the embodiment, the common heat exchange unit 26, the pulsation pump 32, and the switching valve 36 are illustrated as a water circuit for supplying washing water to the first nozzle 40 and the second nozzle 42, but the present invention is not limited thereto. Fig. 7 is a schematic configuration diagram showing the configuration of a toilet cleaning apparatus 10B according to a modification. The toilet cleaning device 10B includes two nozzle units, i.e., a nozzle unit 30A having a first nozzle 40 and a nozzle unit 30B having a second nozzle 42. Further, the water supply passage 20B is provided with a heat exchange unit 26B, a water temperature sensor 28B, and a flow rate sensor 29B branched from the downstream side of the pressure reducing valve 24 of the water supply passage 20. In this modification, the washing water having passed through the water supply line 20 is supplied to the first nozzle 40 via the pulsation pump 32 and the switching valve 36 of the nozzle unit 30A. The washing water having passed through the water supply path 20B is supplied to the second nozzle 42 via the pulsation pump 32B and the switching valve 36B of the nozzle unit 30B.

In this way, in the toilet seat cleaning apparatus 10B of the modified example, the water circuit for cleaning water to the first nozzle 40 and the water circuit for cleaning water to the second nozzle 42 are configured as independent circuits. Therefore, the control device 50 controls the

heat exchange units

26 and 26B to heat the washing water to different temperatures, thereby enabling the washing water of different water temperatures to be ejected from the first and

second nozzles

40 and 42. Further, the controller 50 controls the pulsation pumps 32 and 32B to drive at different pulse frequencies, thereby discharging the washing water of different momentum from the first nozzle 40 and the second nozzle 42. The amounts of washing water ejected from the first nozzle 40 and the second nozzle 42 per unit time are different. Further, the water amounts of the washing water ejected from the first nozzle 40 and the second nozzle 42 may be different by adopting a configuration in which the discharge capacities of the pulsation pumps 32 and 32B are different. In the toilet cleaning apparatus 10B, the operation panel 18B is provided with a first temperature adjustment switch 18i for adjusting the temperature of the cleaning water in the first nozzle 40, a first water potential adjustment switch 18j for adjusting the potential of the cleaning water in the first nozzle 40, a second temperature adjustment switch 18k for adjusting the temperature of the cleaning water in the second nozzle 42, and a second water potential adjustment switch 18l for adjusting the potential of the cleaning water in the second nozzle 42. Thus, the toilet seat device 10B can supply the first nozzle 40 and the second nozzle 42 with the cleaning water having different amounts of water, different water potentials (cleaning strengths), and different water temperatures. Therefore, in the lock/move washing, the cross washing, and the side alternate washing, at least one of the water amount, the water temperature, and the washing intensity of the washing water ejected from the two nozzles can be made different, and therefore, the change of the washing by the washing water ejected from the two nozzles can be increased, and the washing feeling can be further improved.

In the above-described embodiment, the first nozzle 40 and the second nozzle 42 may be supplied with washing water having different water volumes and different water temperatures. For example, the lengths of the

supply hoses

36a and 36b for supplying the washing water to the first nozzle 40 and the lengths of the

supply hoses

36c and 36d for supplying the washing water to the second nozzle 42 may be different from each other, or the heat insulation performance may be different from each other, so that the water volumes may be different from each other by changing the diameters of the hoses and the diameters of the flow paths.

In the embodiment, the

tip members

41 and 43 are made to have the same shape, but the shape is not limited to this, and may be different. Fig. 8 is a structural diagram showing

tip members

41 and 43B of a modification. The tip member 41 in fig. 8(a) has the same shape as in the embodiment. On the other hand, although the diffusion discharge port 43B is formed in the tip member 43B of the second nozzle 42 in fig. 8(B), the straight discharge port 43a is not formed and is omitted. Therefore, in the general washing using one nozzle, the first nozzle 40 is used for the hip washing and the second nozzle 42 is used for the pubic washing. In this modification, since the straight discharge port 43a is not formed in the second nozzle 42, the intersections 1 and 2 and the side alternation 1 illustrated in fig. 5 are not performed. The cross washing of the buttocks washing may be performed using the straight discharge port 41a of the first nozzle 40 and the spread discharge port 43b of the second nozzle 42, or may be performed in accordance with the intersections 3 and 4. The side alternate washing of the buttocks may be performed using the straight discharge port 41a of the first nozzle 40 and the spread discharge port 43b of the second nozzle 42, or may be performed in the side alternate 2. Note that the tip member 41 may be omitted without forming the diffusion ejection ports 41 b.
