Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a cleaning device for cleaning dirt from internal walls of bathrooms, shower rooms, etc., and more specifically, to automate cleaning and save labor on tedious cleaning work. Regarding technology that aims to achieve.

[Background Art] Recently, shower devices have been increasingly used by small families and single people as a convenient means of bathing due to their ease of bath preparation, water conservation, and energy conservation. On the other hand, due to the jetting pressure of the water from the shower, the spray water after cleaning covers the entire bathroom, and the water spray after cleaning contains skin fat, etc., so if you do not wash it before it dries, the dirt will come off. It becomes difficult. Conventionally, when cleaning a bathroom or shower room, it is difficult to reach the ceiling or the upper part of the wall, resulting in an unstable cleaning position, which can be dangerous, such as falling over. Water splashes from the cleaner's head, wets or stains the cleaner's clothes, and also reduces work efficiency.

[Purpose of the invention] This invention was created in view of these problems, and its purpose is to automatically clean the internal walls of bathrooms and shower rooms while saving water by rotating the nozzle using water pressure. It is an object of the present invention to provide a cleaning device that can perform cleaning in a simple manner and save labor in laborious cleaning work.

[Disclosure of the invention] The cleaning device of the invention includes a water passageway 2 along the rotational axis X of a disc-shaped rotating body 1 held rotatably.
A jet passage 3 is formed which communicates with the water passage 2 and extends in the radial direction of the rotating body 1 and has a jet opening 4 opened on the outer peripheral surface of the rotary body 1.
The injection nozzle 5 is inserted in the radial direction of the rotating body 1 and is rotatably attached, and the rotational position of the insertion and installation can be changed freely. The invention is characterized by forming an injection nozzle opening 7 having a diameter of 1.5 mm, and by configuring it in this manner, the above object is achieved. That is, by forming an inclined surface 6 that is inclined with respect to the tangential direction of the rotating body 1 at the injection nozzle opening 7 of the injection nozzle 5 attached to the rotating body 1, the jet water flow hits the inclined surface 6. In this way, the rotating body 1 can be driven and rotated using the water flow, and the injection nozzle 5 held on the rotating body 1 can also be rotated. Injection can be performed while changing the injection position of the water jet from the injection nozzle 5 one after another in the circumferential direction.
By making the rotational position of the spray nozzle 5 freely changeable with respect to the rotating body 1, the slope 6 of the injection nozzle 5 can be changed in various ways, and in this way, the angle of the slope 6 with respect to the water flow can be changed in various ways. In particular, the pressure received by the water flow on the inclined surface 6 can be varied in various ways,
The rotational speed and rotational direction of the rotating body 1 can be changed, and the jetting direction of the water stream can also be changed in various ways, so that the optimum cleaning specifications can be set according to the objects to be cleaned, such as walls, ceilings, corners, etc. In this way, it is possible to automate the troublesome cleaning work, save labor, and perform effective cleaning depending on the object to be cleaned.

Embodiments of the present invention will be described in detail below based on the drawings.

Although FIG. 1 shows an embodiment in which the cleaning device A is installed on the ceiling 8, the cleaning device A may be installed at any location such as a wall surface. Cleaning device A
A cylindrical holder 10 with a flange is attached to a recess 9 in a mounting location such as a ceiling 8, and the cylindrical holder 1
A joint 11 is connected to the lower part of 0 via a tapered screw 12, and a cylindrical rotating shaft 1 is connected to the joint 11.
3 is rotatably held, and a disk-shaped rotating body 1 is integrally attached to the rotating shaft 13. A mechanical seal 15 using a sealing material such as ceramic or polypropylene is interposed between the flange 14 protruding from the upper outer surface of the rotating shaft 13 and the upper surface of the joint 11, and the mechanical seal 15 is inserted through a pipe (not shown) in the ceiling. This prevents water from leaking out from between the holder 10 and the joint 11. As described above, the rotating body 1 rotatably held around the rotation axis X has a rotation axis 13.
A spouting passage 3 is formed which extends in the radial direction of the rotary body 1 in communication with the water passage 2 inside the rotary body 1 and has a spout 4 opened on the outer peripheral surface of the rotary body 1 . Any number of such ejection passages 3 may be formed. The injection nozzle 5 is rotatably attached to the injection port 4 by being screwed in in the radial direction of the rotating body 1, and the rotational position of the injection nozzle can be changed by changing the screwing depth. The injection nozzle 5 has an injection nozzle opening 7 having an inclined surface 6 inclined with respect to the tangential direction of the rotating body 1, forming an acute angle θ with respect to the ceiling surface and opening downward in the installed state shown in FIG. It is formed as follows.

In this way, the injection nozzle opening 7 of the injection nozzle 5 attached to the rotating body 1 is formed with an inclined surface 6 that is inclined with respect to the tangential direction of the rotating body 1, so that the jet water flow hits the inclined surface 6. The rotating body 1 is driven and rotated by using the water flow, and the spray nozzle 5 held on the rotating body 1 is also rotated, so that the water jet is ejected from the spray nozzle 5. Injection is performed while changing the position one after another in the circumferential direction. By changing the screwing position of the injection nozzle 5 with respect to the rotary body 1 and changing the installation rotation position, the inclined surface 6 of the injection nozzle 5 can be changed in various ways. By variously changing the angle of 6,
The pressure received by the water flow on the inclined surface 6 is variously changed, and the rotational speed and direction of rotation of the rotating body 1 are also changed. Moreover, the direction of the water jet can be changed in various ways, allowing effective cleaning to be performed depending on the objects to be cleaned, such as walls, ceilings, corners, etc.

In Fig. 5, the left and right injection nozzles 5, 5 are shown, the right injection nozzle 5a and the left injection nozzle 5b.
Fig. 6 shows the injection direction of Fig. 5.

The central angle α is defined as the positive direction, and this central angle α is the inclination of the inclined surface 6 of the injection nozzle 5a, indicating the installation angle of the injection nozzle 5a. The dotted line area C in FIG. 6 indicates the injection range θb of the left injection nozzle 5b,
The central angle (mounting angle of the injection nozzle 5b) β with respect to the perpendicular D is negative, and the right injection nozzle 5a
It is designed to cancel out the rotational propulsive force caused by the
If the central angles α and β are aligned in the positive or negative direction, a large rotational force can be obtained and high-speed rotation can be achieved, and by making them in opposite directions, the rotational forces cancel each other out. It will rotate at low speed.
If the rotation speed is increased too much, centrifugal force will act and the impact force of the water jetted from the injection nozzles 5a and 5b on the cleaning area will decrease, reducing the cleaning effect, so it is only necessary to set it appropriately. It is desirable to be able to adjust the range, the injection shape based on the injection nozzle port 7 of the injection nozzle 5, the supply water pressure, etc. In the present invention, by changing the mounting angle of the injection nozzle 5, it is possible to obtain not only a cleaning range but also a suitable rotational speed and cleaning impact force.

FIG. 7 shows another embodiment of the injection nozzle 5, in which a nozzle body 16 is screwed into the rotating body 1 so that the position can be changed freely, and a nozzle mouth member 17 is screwed into the nozzle body 16 so that the position can be changed freely. In this way, the mounting position of the nozzle body 16 with respect to the rotating body 1 is adjusted and the nozzle body 1 is adjusted.
By adjusting the mounting position of the nozzle opening member 17 relative to the nozzle opening member 6, the spray range and rotational speed adjustment range can be further increased, making it possible to thoroughly clean bathrooms with complex shapes. The shape of the injection nozzle port 7 of the nozzle port member 17 can be selected from various shapes depending on the type of cleaning. Further, a plurality of nozzle opening members 17 may be attached to the nozzle body 16.

In the embodiment, the installation angle of the injection nozzle 5 can be changed by changing the rotational position at which the injection nozzle 5 is screwed into the rotating body 1, but the configuration can be modified in various ways.

Further, in the embodiment, the ejection passage 3 is oriented substantially horizontally, but it may be oriented diagonally downward or diagonally upward.

Further, in the embodiment, the injection nozzle 5 is connected to the rotating body 1 by screwing, but it may be connected by means other than screwing.
