Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a sanitary cleaning device that can clean private parts hygienically and comfortably.

[Prior art and its problems]

Conventionally, a sanitary washing device having a private part washing function is provided with a washing nozzle that can move forward and backward in the direction of a toilet bowl, and hot water is jetted from this nozzle.

The nozzle body advances and retreats within a sliding guide cylinder provided in a sanitary cleaning device body equipped with a hot water supply source. The nozzle main body and the sliding guide tube must have substantially equal outer and inner diameters so that cleaning water does not leak to the outside from their sliding surfaces, and must be equipped with a packing or the like.

In this type of nozzle structure, if the cleaning water contains dirt or water scale adheres to the outer periphery of the nozzle and the inner surface of the sliding guide cylinder after a period of time, the sliding conditions will deteriorate and the nozzle will not be able to move when moving forward or backward. There are cases. In addition, since the gap between the nozzle outer circumferential surface and the sliding guide cylinder inner circumferential surface is minute, if the nozzle cannot move accurately in the axial direction for some reason, the two may knead together and similarly stop halfway. There is.

Furthermore, when the nozzle stops due to the reasons mentioned above, it can be easily moved by pushing the nozzle with your hand, but it also has the disadvantage that it is unhygienic to touch the nozzle directly. be.

[Purpose of the invention]

The present invention aims to solve the above-mentioned problems, and aims to provide a sanitary cleaning device configured to reliably move the cleaning nozzle forward and backward.

[Structure of the invention]

The configuration of the present invention is that in a sanitary cleaning device having a cleaning nozzle that moves between a storage position and a cleaning position and spouts hot water, when the nozzle movement time between the two positions is longer than a set time, nozzle movement is hindered. The nozzle is determined to have occurred, and the nozzle is moved back to the movement starting point, and then shifted again to the target position.

〔Example〕

The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 is a perspective view of a sanitary washing device according to the present invention, in which 1 is a toilet bowl with a toilet bowl 1a formed inside, 2
3 is a flush water tank, 3 is a heated toilet seat, and 4 is a toilet lid. Furthermore, 5 is a sanitary cleaning device main body, which has a hot water cleaning device 6 and a hot air drying device 7 inside.
Temperature control of both these devices 6, 7 and the heated toilet seat 3,
It has a built-in control section A that controls various operations, and an operation section B is provided on the panel section. Further, 8 is a cleaning nozzle which is a part of the hot water cleaning device 6 and is movable in the direction of the toilet bowl 1a, and 9 is a hot air outlet provided near the nozzle 8. Note that the hot air drying device 7 and heated toilet seat 3 can be installed freely.

FIG. 2 is a control block diagram of the drive system for the cleaning nozzle 8, in which the cleaning nozzle 8 is provided slidably in the axial direction in a sliding guide cylinder 10 communicating with a hot water storage tank for storing hot water, and the electric motor serving as the driving means 11, it can be moved from the storage position to the cleaning position.
The cleaning nozzle 8 can advance to two positions, and the position detection during storage and the three position detection when advancing are performed by position sensors C-1, C-2, and C-3, respectively.

Specifically, the position sensors C-1, C-2, and C-3 are connected to the cleaning nozzle 8 as shown in FIG.
This is done by the magnet M fixed to the magnet M and the reed switches S ₁ , S ₂ , S ₃ arranged on the nozzle holder 5a integrally attached to the sliding guide cylinder ₁₀ . A signal indicating that the cleaning nozzle 8 is located at the storage position, the first cleaning position, and the second cleaning position is input to the control unit A based on the correspondence between S ₂ and S ₃ .

The control unit A is provided with a nozzle drive timer, which controls the cleaning nozzle 8 from the storage position to each cleaning position and vice versa according to the output signals of the position sensors C-1, C-2, and C-3. It measures travel time. When a signal indicating that the cleaning nozzle 8 has reached the target position (for example, the first cleaning position) from the movement start position (for example, the storage position) within a preset time is not input to the control unit A, the cleaning nozzle 8 is The electric motor 11 is controlled to once move backward to the movement start position and then move to the target position again.

That is, the cleaning nozzle 8 does not reach the predetermined position within the set time from the time when the cleaning start switch B ₁ or (stop switch B ₂ ) of the operation part B is operated, and the magnet M and reed switches S ₁ , S ₂ , S If the response in _{step 3} is not possible and no signal is input to the control unit A, it is determined that a problem has occurred in the forward and backward movement of the cleaning nozzle 8, and the cleaning nozzle 8 is moved backwards to the starting point and then moved again toward the target position. It is meant to be moved.

The flowchart of the cleaning nozzle 8 drive control shown in FIG. 4 will be explained below.

In the initial state, the cleaning nozzle 8 is in the storage position as shown in FIG. 3, and at this time the magnet M corresponds to the reed switch _S1 . Cleaning nozzle drive timers are set in the control unit A to be slightly longer than the maximum time required for the cleaning nozzle 8 to reach the first cleaning position and the second cleaning position from this state.

Press the cleaning start switch _B1 to drive the cleaning nozzle 8, and the magnet M will be activated within this timer set time.
When the control section A receives an input signal corresponding to the reed switch _S2 , the driving of the cleaning nozzle 8 is stopped and the hot water jetting process starts at the first cleaning position.

Conversely, when no signal is obtained from the position sensor C-2 within the set time, that is, when the cleaning nozzle 8 has not advanced to a position where the magnet M and reed switch _S2 can correspond, the cleaning nozzle 8 does not advance. It is determined that a failure has occurred. Then, an input is input to the electric motor 11 to once move the cleaning nozzle 8 backward to the storage position, and after a signal is input by the correspondence between the magnet M and the reed switch _S1 , the drive is started again and the cleaning nozzle 8 is moved forward. By this reciprocating motion, it is possible to correct the sliding failure between the cleaning nozzle 8 and the sliding guide tube 10 and reach the first cleaning position.

Further, the same driving form as described above is adopted in the movement of the magnet M and the reed switch _S3 to the corresponding second cleaning position.

Furthermore, even when moving from the cleaning position to the storage position, if an input signal cannot be obtained from the correspondence between magnet M and reed switch _S1 within the set time, the robot will move once to the cleaning position and then move to the storage direction again. It can be stored away.

〔effect〕

As described above, according to the present invention, when the cleaning nozzle moves forward and backward, if the nozzle does not complete its forward and backward movement within a set time, it can be moved in the opposite direction to the intended movement direction to remove the movement obstruction condition. This has the effect that the cleaning nozzle can be moved forward and backward reliably.
