DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable cleaning device for cleaning, for example, the exterior of an automobile, and more particularly, to discharging a power supply of a pump motor of a water supply driving means without directly operating a switch of the device main body. The present invention relates to a water supply driving mechanism that is turned on or off in a state of cleaning water in a hose, and a cleaning device using the same.

[0002]

2. Description of the Related Art People who like to clean a car without dust or the like often go to, for example, a coin-type car wash and wash the car. However, it is troublesome to go to a coin-operated car wash, etc., and it is not economical because a car wash fee is required. Therefore, a long hose and water supply facility at home (specifically, water faucet, etc.) ) Is used to wash the car. That is, in this case, the car washes by connecting the hose port at one end of the hose to a tap for water supply and jetting water from the hose port at the other end of the hose.

[0003] However, in the case where the hose outlet is connected to a tap for spouting water, a water supply facility is required. However, there are many cases where a parking lot such as an apartment complex does not have a water supply facility.

[0004]

By the way, there is a case where it is not necessary to blow out the washing water from the hose port, for example, while the detergent is being applied to the exterior of the vehicle during the car washing. If the washing water is spouted from the hose port even when the spouting of the washing water is not necessary, the washing water is wasted and the power supply of the pump motor for supplying the washing water is also wasted. A method of mechanically stopping water at the hose port is also conceivable. However, excessive water pressure is applied to the hose port, and there is a risk that the pump and the pump motor may break down.

Accordingly, the present invention provides a water supply drive mechanism having a simple structure for automatically driving or stopping the drive of the water supply drive means in accordance with the state of the liquid between the water supply drive means and the water stopping means, and It is an object of the present invention to provide a cleaning device using the same.

[0006]

According to a first aspect of the present invention, there is provided a water supply driving mechanism for supplying a liquid such as water, and a water supply driving means connected to the water source for sucking and discharging the liquid. And an application unit that applies a voltage for driving the water supply driving unit, a discharge port from which the liquid is discharged from the water supply driving unit, and a water stopping unit that stops discharging from the discharge port. A water stop detecting means for detecting that water is stopped by the water stopping means by moving the moving means, and a water supply driving means by the water stopping detecting means; Switching means for controlling the application of a voltage to the water supply means, wherein when the water stoppage is detected by the water stoppage detection means, the application of the voltage to the water supply drive means is stopped.

In the water supply drive mechanism according to the first aspect of the present invention, when the water supply drive means is driven by the switching means, the liquid is supplied and discharged from the discharge port. In a state where the liquid is being discharged from the discharge port, when the water stopping means is operated to stop the discharge from the discharge port, the pressure of the liquid increases. Therefore, since the moving means moves, the water stopping detecting means detects that water is stopped, and the driving of the water supply driving means automatically stops.

To discharge the liquid again from the discharge port, the water stopping means is turned off and opened. Then, the liquid is discharged from the discharge port, so that the pressure of the liquid decreases and the moving means moves. For this reason, the water stop detection means detects that the water stop state has been released, and the water supply drive means is automatically driven again. When the car washing is completed, for example, after pressing the water stopping means, the switching means is operated to turn off the power.

In the water supply driving mechanism according to the first aspect of the present invention, the driving of the water supply driving means is stopped when the water is not required to be discharged during the car washing, so that the water in the water storage tank is wasted. Not only is it not used, and the power supply for supplying water is not wasted, but also there is no risk of causing failure of each part.

According to the water supply drive mechanism of the first aspect of the present invention, the water stoppage detecting means detects the state of the water pressure between the water supply drive means and the water stoppage means to apply the voltage to the water supply drive means. Alternatively, since the application is automatically stopped, the water supply driving means is driven only at the time of cleaning, and the water and the power supply are effectively used, thereby contributing to energy saving.

Further, according to the water supply driving mechanism according to the first aspect of the present invention, the water stoppage detecting means can be stopped by the water supply driving means without operating the switching means disposed on the main body of the cleaning device. The state of the water pressure between the water supply means is detected, and the application of the voltage to the water supply drive means or the stop of the application is automatically performed based on the detection result. Inconveniences such as breakage of the pump or the pump motor are avoided.

As shown in FIG. 3, the sliding portion 32 includes a cylindrical cylinder 34 and a sliding body 36 (FIG. 2) as a moving means which slides opposite the outer peripheral surface 34A of the cylinder 34.
And a coil spring 38 as urging means for constantly urging the sliding body 36 toward the joint 22C. The sliding body 36 is formed of, for example, a hard synthetic resin, metal, or the like, and has rigidity that does not easily deform.

At the tip of the cylinder 34, a circumferential groove 34C is formed along the circumferential direction, and the O-ring 39 is fitted into the circumferential groove 34C. Then, the distal end surface of the O-ring 39 is pressed against the inner peripheral surface of the sliding body 36, and watertightness is maintained.
That is, even when the sliding body 36 slides on the O-ring 39, the cleaning water does not leak from the gap between the sliding body 36 and the cylinder 34.

The base of the cylinder 34 has a plurality of slots 34B cut out at predetermined angular intervals in the circumferential direction. And the donut-shaped stopper 3
The cylinder 34 is fixed to the joint 22C by fitting the projection 35A of No. 5 into the elongated hole 34B.

A substantially ring-shaped hooking piece 36B for hooking the hooking portion 38B of the coil spring 38 is formed on the surface 36A facing the hooking portion 38A of No. 6. Therefore, the coil spring 38 always urges the sliding body 36 toward the joint 22C.

Note that, as shown in FIG.
The position of 0 is set so that the sliding body 36 is in contact with the O-ring 39 and does not come out of the cylinder 34 when the sliding body 36 moves (the state shown in FIG. 5).
As shown in FIG. 3, a cylindrical stopper wall 31 is provided around the sub-switch 30. And
The operator 30A protrudes from the stopper wall 31, and the sliding member 36
First, is pressed against the operator 30A (see the imaginary line in FIG. 3). Next, as shown in FIG. 5, the sliding body 36 abuts on the distal end surface 31A of the stopper wall 31, and further sliding is restricted. Therefore, the sliding body 36 is
There is no escape from 4.

As shown in FIG. 1, the water discharge hose 18 is cylindrical and has a length of about 10 meters.
The brush unit 20 is detachably connected to B. A water stopcock 40 as water stoppage means is movably disposed on the grip portion 20A side of the brush part 20, and the water stopcock 40 has a conventionally well-known configuration. That is, a valve body (not shown) is integrally formed at a position inside the brush portion 20 of the water stopcock 40, and a soft packing is attached around the valve body. Therefore, the valve body is pressed against a valve seat (not shown) formed in the brush portion 20, and the passage of the washing water, that is, the hose path from the pump 22 to the water stopcock 40 (hereinafter, simply referred to as "hose path") is closed. It is supposed to be. In addition, the passage of the washing water is opened by pulling the water stopcock 40. The structure of the water stopping means is not limited to the structure of the present embodiment as long as the washing water from the pump 22 can be stopped.

Brush bristles 42 are implanted on the brush portion 20 on the side opposite to the water stopcock 40. The brush bristles 42 are made of soft synthetic resin or natural bristles. Further, a spout (not shown) which forms a part of the passage of the washing water is formed on the surface of the brush bristles 42 in the brush portion 20.
Wash water is spouted from the spout.

In the present embodiment, the ejection port is the brush portion 2.
Although it is formed to be zero, the ejection port of the present invention may be merely the tip of the discharge hose 18. In the present embodiment, the brush portion 20 is attached to the distal end 18B of the discharge hose 18, but a sponge or the like may be attached instead of the brush portion 20.

Next, the operation of the present embodiment will be described. First, as shown in FIG. 1, when the main switch 28 is turned from an off state (a state shown by a broken line in FIG. 1) to an on state (a state shown by a solid line in FIG. 1), the pump 22 is driven and the inside of the water storage tank 12 is turned on. Is sent to the brush unit 20 via the pump 22. For this reason, the cleaning water is spouted from a spout (not shown) of the brush unit 20.

Next, in a state in which the washing water is being ejected from the ejection port of the brush portion 20, when the water stopcock 40 is pressed to close the hose path, the ejection of the washing water is stopped. As the water is pumped, the water pressure in the hose path increases. Then, when the pressure of the washing water becomes equal to or higher than a certain value (that is, when the pressure becomes larger than the urging force of the coil spring 38), the sliding body 36 slides toward the sub-switch 30 and presses the operating element 30A. Therefore, the sub-switch 30 is turned off, and the power supply circuit is opened. That is, the power supply voltage is not applied to the motor 24, and the driving of the pump 22 is stopped.

In the present embodiment, the driving of the pump 22 is stopped when the jetting of the washing water is not necessary in the middle of the car washing. For example, the washing water is applied while the detergent is applied to the exterior of the vehicle. It does not spout from the spout of the brush part 20. That is, according to the present embodiment, when it is not necessary to jet the washing water as described above, the water stopcock 40
As a result, the ejection of the washing water is stopped, the power supply circuit is opened, and the driving of the motor 24 is stopped.

Therefore, according to the present embodiment, the power of the pump 22 is automatically turned off or on in accordance with a change in the pressure of the washing water in the hose path. The water and the battery 26 as a power source are prevented from being wasted, and the cleaning water and the power source are effectively used, thereby contributing to energy saving.

Further, according to the present embodiment, the apparatus body 16
A, without operating the main switch 28 disposed at the position A, the slide portion 32 and the sub-switch 30 detect the increase or decrease of the water pressure in the hose path and the pump 22
Since the application of the voltage to or the stop of the application of the voltage is automatically performed, inconveniences such as breakage of the water supply hose 14 and detachment from the water supply driving means due to the stop of the driving of the pump 22 are avoided.

Further, according to the present embodiment, the sliding member 36
Is formed so as not to be easily deformed, and is configured to slide with respect to the cylinder 34, so that the sliding body 36 is reliably moved to operate the sub-switch 30. According to the present embodiment, the cylinder 34 and the sliding body 36
Since the material itself is not deformed, the degree of deterioration is small (durability is good), and it can be used for a long time.

According to the present embodiment, for example, a power supply switch for the pump 22 is provided near the ejection port of the discharge hose 18 and the cost is lower than when the switch wiring is provided, and the diameter of the water supply hose 14 is reduced. It will be shorter. Further, according to the present embodiment, the cost is lower than when an optical remote controller which does not require the wiring of the switch is used.

When the washing water is ejected again from the ejection port of the brush section 20, the water stopcock 40 is pulled to open the hose path. When the hose path is opened, washing water is spouted from the spout of the brush section 20, and the water pressure in the hose path decreases. When the pressure of the washing water becomes equal to or less than a predetermined value, the sliding body 36 slides toward the joint 22C by the urging force of the coil spring 38 and separates from the operator 30A.
As a result, the operator 30A returns to the initial position shown in FIG. 3 by the spring (not shown) in the sub-switch 30, and the sub-switch 30 is turned on. for that reason,
Since the power supply circuit becomes a closed circuit, the power supply voltage is applied to the motor 24, and the pump 22 is restarted. Therefore, since the cleaning water in the water storage tank 12 is supplied, the cleaning water is spouted from the spout of the brush unit 20. Then, when the car washing is completed, the main switch 38 is turned off, for example, after the water stopcock 40 is pressed.

(Second Embodiment) A water supply drive mechanism of a cleaning apparatus according to a second embodiment of the present invention will be described with reference to FIG. Note that the sliding portion 50 of the present embodiment includes a sliding body 66.

The biasing force of the coil spring 38, one end of which is hooked on a hook 66B formed on the surface 66A of the sliding body 66,
However, since the sliding member 66 is restricted by the stopper portion 52, the sliding member 66 does not move to the hook bar 37 more than necessary.

The groove 64C of the cylinder 64 is formed substantially at the center of the inner peripheral surface of the cylinder 64 in the axial direction. This is to prevent the O-ring 39 from separating from the sliding body 66 that slides. Further, a locking groove 54 is formed along the circumferential direction at the tip of the inner peripheral surface of the cylinder 64, and a lid 56 formed with a projection 56 </ b> A that fits into the locking groove 54 is connected to the opening of the cylinder 64. Is closed. That is, the lid 56 is fixed to the cylinder 64 by fitting the protrusion 56 </ b> A into the locking groove 54.

The surface 56B of the lid 56 facing the sliding body 66
, A sub-switch 60 is fixed. The sub-switch 60 of the present embodiment is a push button type, and the sub-switch 60 is switched from off to on when the operator 62 of the sub-switch 60 is pressed by the sliding body 66.

The lid 56 has a stopper 5 for preventing the sliding body 66 from pressing the main body of the sub-switch 60 itself.
6D is formed. A plurality of air holes 56E for circulating air in the upper part of the cylinder 64 are formed around the sub-switch 60 of the lid 56.

In the present embodiment, since the sliding body 66 that slides is always located in the cylinder 64, the sliding body 66 moves smoothly and reliably. The other configuration and operation and effect are the same as those of the first embodiment, and the description is omitted.

The sub-switch 3 of each of the above embodiments is
The reference numerals 0 and 60 are not limited to those in the above-described embodiments. For example, an optical sensor (photo interrupter) or the like may be used as long as the detection signal can be switched by the movement of the sliding members 36 and 66. In addition, the configuration of the slide portion 32 is not limited to the above embodiments,
If the moving means such as a sliding body that moves due to a change in water pressure is formed so as not to be easily deformed, it can be arbitrarily changed.

In each of the above embodiments, the stoppers 31 and 56D are provided to prevent the sliding bodies 36 and 66 from directly pressing the main body of the sub-switches 30 and 60. The stoppers 31 and 56D may be unnecessary by increasing the rigidity or the like. In each of the above embodiments, the O-ring 39 is provided for waterproofing (that is, the O-ring 39 is provided).
This is an example in which a change in water pressure can be accurately detected. However, if the sliding bodies 36, 66 can move in response to a change in water pressure, for example, the sliding bodies 36, 66 or the cylinders 34, 6
The opposing outer peripheral surfaces of 4 may be coated with rubber or the like.
