The female screw portion 15 that is screwed in is pushed and pulled in the horizontal direction, and one end of the jet pipe 14 is also pushed and pulled. Along with this, the sliding bearing 18 at the other end of the ejection pipe 14 slides along the horizontal smooth guide 19, so that the ejection pipe 14 moves in the horizontal direction. That is, when the horizontal driving unit 17 rotates the horizontal screw guide 16, the ejection pipe 14 moves in the horizontal direction.

When the ejection pipe 14 is moved to the housing 4 side, the ejection pipe 14 enters through the spaces 13a and 13b of the housing 4 as shown in FIG.
It is housed in the housing case 4.

The horizontal drive section 17 is provided with a first horizontal limit switch 21a. When the ejection pipe 14 is accommodated in the accommodating housing portion 4, the first horizontal limit switch 21a comes into contact with the female screw portion 15 and is turned on.

At the tip of the protective casing 10a, the horizontal screw guide 16 is provided with a bearing 22 as shown in FIG.
The bearing 22 is provided with a second horizontal limit switch 21b. The second horizontal limit switch 21b comes into contact with the female screw portion 15 and is turned on when the ejection pipe 14 reaches the tips of the protective housing portions 10a and 10b.

The first hose casing 23 is fixed to the lower side of the protective casing 10a. These protective housing parts 10a
Between the first hose housing 23 and the first hose housing 23 to connect the two.
4 are formed. One end of the jet pipe 14 is bent downward at a right angle inside the female screw portion 15, reaches the first hose housing 23 via the slot 24, and is connected to the first hose 25. The first hose 25 is a second hose housing 26.
Is also connected to the shaft 28 of the hose drum 27 on the inner side of, and connects the jet pipe 14 and the shaft 28 of the hose drum 27.

The first hose 25 is long enough to connect the jet pipe 14 and the shaft 28 of the hose drum 27 even if the jet pipe 14 is moved to the tip side of each of the protective casings 10a and 10b. Is set to

The hose drum 27 is the second hose housing 26.
It is rotatably supported inside the. A second hose 29 is wound around the hose drum 27 as shown in FIG. A hollow chamber 31 is formed inside the shaft 28 of the hose drum 27, and the second hose 29 is provided in the hollow chamber 31.

When the second hose 29 drawn out from the second hose housing 26 is pulled downward, the hose drum 27 rotates, the second hose 29 is sent out from the hose drum 27, and the spiral spring 37 is wound. . Thereafter, when the second hose 29 is released, the hose drum 27 reversely rotates due to the urging force of the spiral spring 37, the second hose 29 is wound around the hose drum 27, and returns to the original state.

For this reason, when the U-shaped frame 3 is moved up and down between the floor and the ceiling of the toilet, the second hose 29 is sent out from the hose drum 27 of the second hose housing 26, or this hose is moved. It is wound up on the drum 27. As a result, the second hose 29 does not sag between the second hose housing 26 and the floor of the toilet, and the hose drum 27 and the pressure feeding portion 35 are not slackened.
Connect.

On the other hand, the control system of this indoor cleaning device is shown in FIG.
It is configured as shown in.

In FIG. 7, the first vertical optical sensor 12
As described above, the a and the second vertical optical sensor 12b detect that the U-shaped frame 3 has reached the vicinity of the ceiling and the vicinity of the floor, as described above.

The first horizontal limit switch 21a and the second
The horizontal limit switch 21b detects that the ejection pipe 14 has been accommodated in the accommodation housing portion 4 and that the ejection pipe 14 has reached the tips of the protective housing portions 10a and 10b as described above.

The door switch 41 is attached to the knob 43 of the door 42 of the toilet shown in FIG. 1, detects opening / closing of the door 42, and informs the controller 44 of this fact each time the door 42 is opened / closed twice. Notice. This double opening / closing of the door 42 suggests the first opening / closing of the door 42 when the user enters the toilet and the second opening / closing of the door 42 when the user exits the toilet. The control unit 44 is notified of the second opening / closing.

The timer 45 measures time, and notifies the control unit 44 of this at a predetermined time.

The pressure feeding section 35 selectively feeds either water or air, as described above, and has a wash water pump 46, an air compressor 47, and a switching valve 48.

The horizontal drive unit 17 moves the jet pipe 14 in the horizontal direction as described above.

The vertical drive units 6a and 6b raise and lower the U-shaped frame 3 as described above.

The display section 49 displays that the toilet is being washed.

The control unit 44 controls each horizontal limit switch 2
1a, 21b, the vertical light sensors 12a, 12b, and the detection output from the door switch 41, or the output from the timer 45, in response to the pressure feed unit 35, the horizontal drive unit 17, each vertical drive unit 6a, 6b, and The display unit 49 is controlled.

Now, in such a structure, the toilet is cleaned by the following procedure.

First, when the user enters the toilet, the door 42 of the toilet is opened and closed for the first time. When this user leaves the toilet after adding the toilet, the door 42 is opened and closed a second time. At this time, the door switch 41 detects the second opening / closing of the door 42 and notifies the control unit 44 of this fact.

In response to this, the control unit 44 switches the switching valve 48 to the washing water pump 46 side, and connects the washing water pump 46 to the second hose 29. In addition, the control unit 44
Activates the horizontal drive unit 17 to rotate the horizontal screw guide 16 to start the horizontal movement of the ejection pipe 14. Further, the control unit 44 causes the display unit 49 to display that the toilet is being cleaned.

Normally, the ejection pipe 14 is housed inside the housing case 4, and the U-shaped frame 3 is the second vertical optical sensor 12.
It is located at approximately the same height as b. When the horizontal drive unit 17 is activated, the ejection pipe 14 moves horizontally from the housing case 4 to the tips of the protective housings 10a and 10b.

Subsequently, the control unit 44 activates the wash water pump 46. The wash water pump 46 pumps water to the second hose 29 via the switching valve 48. This water is
As described above, the second hose 29 to the hose drum 27
It is guided to the first hose 25 through the hollow chamber 31, further reaches the ejection pipe 14 from the first hose 25, and is ejected from each ejection hole 14 a of the ejection pipe 14.

Therefore, the jet pipe 14 sprinkles water on the floor of the toilet while moving horizontally. This cleans the floor of the toilet.

The jet pipe 14 is provided in each of the protective casings 10a, 1
When it moves to the vicinity of the tip of 0b, the second horizontal limit switch 21b comes into contact with the female screw portion 15 and is turned on. In response to this, the control unit 44 controls the horizontal drive unit 17 to rotate the horizontal screw guide 16 in the reverse direction. This allows
The jet pipe 14 returns to the housing case 4 from the vicinity of the tips of the protective housings 10a and 10b.

At about the same time, the control unit 44 stops the wash water pump 46, switches the switching valve 48 to the side of the air compressor 47, and the air compressor 47.
Is connected to the second hose 29, and the air compressor 4
Start 7.

The air compressor 47 sends air to the second hose 29 through the switching valve 48 under pressure. This air reaches the ejection pipe 14 through a path similar to that of water,
The gas is ejected from each ejection hole 14a of the ejection pipe 14.

Therefore, the ejection pipe 14 ejects air to the floor while returning from the tips of the protective casings 10a and 10b to the accommodating casing 4. Draining is performed by this jet of air.

When the jet pipe 14 enters the housing case 4 and is housed therein, the first horizontal limit switch 2
1a comes into contact with the female screw portion 15 and is turned on. In response to this, the control unit 44 stops the horizontal drive unit 17 and the air compressor 47, and stops the display on the display unit 49.

Thus, when the user uses the toilet,
The jet pipe 14 reciprocates once in the horizontal direction, and water and air are jetted sequentially from the jet pipe 14 to clean the floor of the toilet.

In addition, in this indoor cleaning device, not only is the floor cleaned every time the toilet is used, but the entire toilet is cleaned at a predetermined time.

This time is set, for example, in the middle of the night when the frequency of use of the toilet is low, and this time is indicated in the timer 45. At this time, the timer 45 notifies the control unit 44 of this.

In response to this, the control unit 44 switches the switching valve 48 to the washing water pump 46 side, and the horizontal drive unit 1
7 is activated to display on the display unit 49 that the toilet is being washed. As a result, similarly to the above, water is jetted from the jet pipe 14 while the jet pipe 14 moves toward the tips of the protective casings 10a and 10b.

The control unit 44 activates not only the horizontal drive unit 17 but also the vertical drive units 6a and 6b. As a result, the U-shaped frame 3 rises from the position of substantially the same height as the second vertical optical sensor 12b.

The jet pipe 14 is used for each of the protective casings 10a, 1
Move to the tip of 0b and move to the 2nd horizontal limit switch 2
When 1b is turned on, the control unit 44 controls the horizontal drive unit 17 to rotate the horizontal screw guide 16 in the reverse direction, stop the wash water pump 46, switch the switching valve 48, and activate the air compressor 47. As a result, air is ejected from the ejection pipe 14 while the ejection pipe 14 moves toward the housing 4 as in the previous case.

When the jet pipe 14 enters the housing 4 and the first horizontal limit switch 21a is turned on,
The control unit 44 controls the horizontal drive unit 17 to reversely rotate the horizontal screw guide 16 again, restore the direction of rotation of the horizontal screw guide 16 to the original direction, stop the air compressor 47, switch the switching valve 48, The wash water pump 46 is started.

Similarly thereafter, the ejection pipe 14 repeatedly reciprocates in the horizontal direction, ejects water on the outward path and ejects air on the return path.

When the U-shaped frame 3 moves up to the vicinity of the ceiling and is detected by the first vertical optical sensor 12a, the control unit 4
4 controls each vertical drive part 6a, 6b to rotate each vertical screw guide 1a, 1b in the reverse direction. As a result, the U-shaped frame 3 descends from the vicinity of the ceiling and returns to the original position.

At the time of this descending, the jet pipe 14 is
It repeatedly reciprocates in the horizontal direction and alternately ejects water and air.

The U-shaped frame 3 descends to the vicinity of the floor, and the second frame
When detected by the vertical light sensor 12b, the control unit 44
Stops each vertical drive unit 6a, 6b.

After that, the control unit 44 causes the ejection pipe 14 to enter the housing case 4, and the first horizontal limit switch 2
When the first horizontal limit switch 21a is turned on, the horizontal drive unit 17 and the air compressor 47 are stopped, and the display on the display unit 49 is stopped.

As a result, the U-shaped frame 3 and the ejection pipe 1
4 returns to the original position, and the cleaning of the entire toilet is completed.

By the way, this indoor cleaning device can be applied to various toilets, shower rooms, etc., but it must be appropriately modified according to each room.

For example, when applied to an existing toilet,
Since it is difficult to use under the floor, each vertical drive unit and pumping unit are installed on the ceiling side. This existing toilet floor does not necessarily have a drain hole, but if the water on the floor naturally drains through the gap under the door, it is not necessary to provide a drain hole. .

Further, the shape of the U-shaped frame may be modified as shown in FIG. Here, the cylindrical casing 51 is used as a U-shaped frame, and a horizontally elongated opening is formed in the cylindrical casing 51, and a pair of rubber strips are formed on the upper and lower edges of the opening. 52a and 52b are adhered.

Although such a frame is provided so as to protect the screw guide, the ejection pipe, etc. and not to impair the aesthetics of the room, it can be omitted if not necessary.

Further, respective modified examples of details of the indoor cleaning device are shown in FIGS. 9 to 11. In the modification of FIG. 9,
Female thread 15, jet pipe 14 and horizontal screw guide 1
6 are different from each other in connection structure, and the bands 13a and 13b are omitted. Further, in the modification of FIG. 10, the ejection pipe 14 is connected to the female screw portion 15 via the L-shaped joint pipe 53, and the first and second horizontal limit switches 21a,
21b is arranged on the female screw portion 15. Furthermore, FIG.
In the modified example, one end of the ejection pipe 14 is bent horizontally at a right angle inside the female screw portion 15 and is guided rearward.

FIG. 12 shows another embodiment of the indoor cleaning device of the present invention. In this indoor cleaning device, the vertical movement of the U-shaped frame is omitted, and the ejection pipe is moved only in the horizontal direction to clean only the floor.

In the same figure, a U-shaped frame 61 is composed of respective protective housing portions 62a and 62b and a housing housing portion 63,
The protective casing 62a is made higher than the other casings. A horizontal screw guide 64 is axially supported in the protective casing 62a, and the horizontal screw guide 64 is screwed into the female screw portion 65.

The inside of the U-shaped frame 61 has a horizontally elongated opening, and rubber bands 66a and 66b are provided at the upper and lower edges of this opening. One end of the ejection pipe 67 penetrates through the spaces 66a and 66b of the protective casing 62a and is connected to the female screw portion 65. One end of the jet pipe 67 is bent downward at a portion of the female screw portion 65 and connected to the hose 68. In the protective casing 62a, the length of the hose 68 is secured so as not to hinder the movement of the ejection pipe 67.

The other end of the jet pipe 67 is connected to the protective casing 62.
It penetrates into b and is connected to the roller 69. The roller 69 rotates on the guide rail 71 of the protective casing 62b and guides the other end of the ejection pipe 67 along the guide rail 71.

Here, the horizontal screw guide 64 is rotated to move the jet pipe 67 to the tips of the protective casing portions 62a and 62b. When the jet pipe 67 moves to the vicinity of the tips of the protective housing portions 62a and 62b and the female screw portion 65 contacts the limit switch 72, the limit switch 72 is turned on. In response to this, the horizontal screw guide 64 is reversed and the ejection pipe 67 is moved to the housing 63. This ejection pipe 67 is used for the housing 6
3, the internal thread 65 contacts the limit switch 73, and the limit switch 73 is turned on,
The jet pipe 67 is stopped.

While the jet pipe 67 is reciprocating in this way, water and air are jetted sequentially from the jet pipe 67.

In this indoor cleaning device, since the U-shaped frame 61 is not moved in the vertical direction, the U-shaped frame 61 is fixed. For this reason, as shown in FIG.
Is provided on the outer wall surface 75 of the chamber, and the horizontal screw guide 64 is penetrated through the wall of the chamber to be connected to the horizontal drive unit 74.

Of course, as shown in FIG.
