TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cleaning device that performs cleaning by ejecting a cleaning liquid or water.
[0002]
[Prior art]
As a cleaning device, there is one described in Japanese Patent Application Laid-Open No. 2000-51800, which was invented by the present inventors and already published. There are various types of cleaning devices. Among them, a tank in which a cleaning liquid is stored, a pressurizing means for introducing compressed air into the tank to pressurize the cleaning liquid, and a pressurizing means for pressurizing the cleaning liquid. Some have a fluid pipe for guiding the cleaning liquid in the tank to the outside of the tank, and an opening / closing gun attached to the tip of the fluid pipe to open and close the fluid pipe. In such a cleaning device, by opening the opening / closing gun, the pressurized cleaning liquid is guided from the tank to the opening / closing gun via a fluid pipe and is ejected from the opening / closing gun, and the cleaning liquid is ejected from the opening / closing gun. This causes foaming due to a pressure change at the time of the cleaning or an impact at the time of colliding with the object to be cleaned.
[0003]
[Problems to be solved by the invention]
By the way, as described above, in the conventional cleaning device, bubbles are generated due to a pressure change when ejected from the opening / closing gun or an impact when colliding with the object to be cleaned. In this case, the cleaning liquid can be sufficiently foamed. There was a problem that could not be done. If the cleaning liquid cannot be sufficiently foamed as described above, a large amount of cleaning liquid is required to obtain the same cleaning effect, and the cleaning efficiency is deteriorated.
[0004]
In addition, when washing with water instead of the above-mentioned washing liquid, washing cannot be carried out effectively only by squirting water, and washing efficiency is poor, such as not being able to sufficiently wash even if a large amount of water is used. turn into.
[0005]
Therefore, an object of the present invention is to provide a cleaning device capable of improving cleaning efficiency.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 includes a tank in which a cleaning liquid or water is stored, a pressurizing means for introducing gas into the tank to pressurize the cleaning liquid or water, and A cleaning device comprising: a flexible fluid pipe for guiding a cleaning liquid or water in the tank pressurized by a pressure means to the outside of the tank; and an opening / closing gun attached to a tip of the fluid pipe to open and close the fluid pipe. In the apparatus, a gas pipe for introducing a gas into the fluid pipe is provided at an intermediate position of the fluid pipe, and the gas pipe has a flexible internal nozzle extending to the opening / closing gun side at a distal end side. Features.
[0007]
Thus, for example, when the cleaning liquid is introduced into the tank and the opening / closing gun is opened, the pressurized cleaning liquid is guided from the tank to the opening / closing gun via the fluid pipe, and is ejected from the opening / closing gun. The gas is introduced into the cleaning liquid from the internal nozzle of the gas pipe provided in the nozzle, and the cleaning liquid is foamed. In addition, since the internal nozzle has flexibility, the internal nozzle vibrates due to discharge of gas, and as a result, the cleaning liquid is foamed more effectively. In addition, since the fluid pipe has flexibility, the cleaning liquid pulsates, and from this point, the cleaning liquid is more effectively foamed.
[0008]
Also, for example, by putting water into a tank and opening the opening / closing gun, pressurized water is guided from the inside of the tank to the opening / closing gun via the fluid pipe and ejected from the opening / closing gun. The gas is introduced into the water from the internal nozzle of the provided gas pipe to make the water particles fine. In addition, since the internal nozzle has flexibility, the internal nozzle vibrates due to discharge of gas, and as a result, water is more effectively made into fine particles. In addition, since the fluid pipe has flexibility, pulsation can be generated in water and can be ejected with the pulsation.
[0009]
According to a second aspect of the present invention, in the first aspect of the invention, the gas pipe introduces the gas introduced into the tank by the pressurizing means into the fluid pipe.
[0010]
As described above, since the gas introduced into the tank for pressurizing the cleaning liquid or water by the pressurizing means is introduced into the fluid pipe by the gas pipe, the pressurizing means is connected to the pressurizing source of the cleaning liquid or water and the fluid pipe. Also serves as a gas supply source.
[0011]
According to a third aspect of the present invention, in the first or second aspect, an adjustment valve capable of adjusting an opening / closing amount of the fluid pipe is provided closer to the tank than the gas pipe connection position of the fluid pipe. It is characterized by:
[0012]
Accordingly, when the opening and closing amount of the fluid pipe is adjusted by the adjustment valve, the flow rate of the cleaning liquid or water with respect to the flow rate of the gas introduced into the fluid pipe by the gas pipe is adjusted, and in the case of the cleaning liquid, the state of foaming can be adjusted. In the case of water, the size of the grains can be adjusted.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
A cleaning apparatus according to an embodiment of the present invention will be described below with reference to FIG.
[0014]
FIG. 1 is a cross-sectional view illustrating the cleaning device of the present embodiment.
The cleaning device 11 according to the present embodiment is used for cleaning, for example, a home air conditioner, and includes a tank 12 in which a cleaning liquid or water is stored, and compressed air (gas) introduced into the tank 12. An air compressor (pressurizing means) 13 for pressurizing the cleaning liquid or water; a flexible fluid pipe 14 for guiding the cleaning liquid or water in the tank 12 pressurized by the air compressor 13 to the outside of the tank 12; An opening / closing gun 15 attached to the tip of the fluid passage 14 to open and close the flow path in the fluid pipe 14.
[0015]
The tank 12 includes a tank body 21 provided with a liquid inlet 20 for liquid introduction at an upper portion, and a lid 22 that closes the liquid inlet 20 by being screwed into the liquid inlet 20 of the tank body 21. And A liquid outlet 23, a gas inlet 24, and a gas outlet 25 are provided in the upper part of the tank body 21 side by side with the liquid inlet 20.
[0016]
The discharge side of the air compressor 13 is connected to a gas inlet 24 of the tank body 21 via a pipe 27, and introduces compressed air into the tank 12 from the gas inlet 24.
[0017]
The fluid pipe 14 is connected to the liquid outlet 23 and extends to near the bottom of the tank body 21, and an external pipe connected to the inner pipe 29 and extending outside the tank 12. And the outer tube portion 30 is flexible enough to pulsate the fluid passing therethrough.
[0018]
The opening / closing gun 15 is attached to the distal end of the outer pipe portion 30 of the fluid pipe 14, and opens and closes a flow path in the fluid pipe 14 by swinging a lever 32. An external nozzle 33 for discharging a fluid is provided at the tip of the opening / closing gun 15.
[0019]
The external nozzle 33 is detachable with respect to the opening / closing gun 15, and an optimal nozzle is attached according to a cleaning operation.
[0020]
For example, a pinpoint nozzle that has a cylindrical shape and can eject a pinpoint fluid without deformation when the internal fluid passes, and a pinpoint nozzle that can eject the pinpoint fluid without deformation when the internal fluid passes and is deformed by bending by hand And a flexible nozzle that can maintain a deformed state, and the whole is formed of a flexible material such as nylon, Teflon (registered trademark), polyurethane, or polypropylene, and has a width in one direction orthogonal to the length direction. It has a so-called flat shape that is smaller than the width in the direction perpendicular to the length direction and the direction perpendicular to the one direction, and a flat nozzle or the like that reciprocates in the one direction due to the passage of an internal fluid is used as the external nozzle 33. Is done.
[0021]
A gas pipe 37 for introducing compressed air into the fluid pipe 14 is introduced at an intermediate position (between the tank 12 and the opening / closing gun 15) of the external pipe section 30 of the fluid pipe 14. The gas pipe 37 is connected to the gas outlet 25 of the tank 12, and introduces compressed air introduced into the tank 12 by the air compressor 13 into the fluid pipe 14.
[0022]
A flexible cylindrical internal nozzle 38 extending toward the opening / closing gun 15 is provided at a distal end portion of the gas pipe 37 disposed inside the fluid pipe 14. The base end is supported by the fluid pipe 14 via a support member 39. The inner nozzle 38 is a cylindrical member entirely formed of a flexible material such as nylon, Teflon (registered trademark), polyurethane, or polypropylene to have a substantially constant thickness, and is formed in one direction orthogonal to the length direction. Has a so-called flat shape, in which the width in the direction orthogonal to the length direction and smaller than the width in the direction orthogonal to the one direction is at least partly reciprocated only in the one direction by the passage of the internal fluid. That is, it vibrates.
[0023]
Further, on the tank 12 side of the connection position of the gas pipe 37 of the fluid pipe 14, an adjustment valve 40 capable of manually adjusting the opening / closing amount of the flow path in the fluid pipe 14 is provided. That is, the adjustment valve 40 can adjust the flow path in the fluid pipe 14 to an arbitrary opening degree from fully closed to fully opened by the rotation of the handle portion 41.
[0024]
The operation of the cleaning device 11 having the above configuration will be described.
[0025]
First, the cleaning liquid is introduced into the tank main body 21 through the liquid inlet 20 with the lid 22 removed at a level lower than the gas inlet 24 and the gas outlet 25, and the liquid inlet 20 is covered. The body 22 is closed. Then, in this state, compressed air is introduced into the tank 12 by the air compressor 13. Then, the cleaning liquid in the tank 12 is pressurized. Then, when the operator operates the lever 32 to open the open / close gun 15, the cleaning liquid in the pressurized tank 12 is guided to the open / close gun 15 via the fluid pipe 14, and is externally connected to the open / close gun 15. It is ejected from the nozzle 33.
[0026]
At this time, the compressed air introduced into the tank 12 by the air compressor 13 is also ejected from the gas outlet 25 through the internal nozzle 38 of the gas pipe 37 provided at a position halfway through the fluid pipe 14. Compressed air is introduced into the cleaning liquid flowing through the fluid pipe 14 by the ejection of the compressed air from the internal nozzle 38, and the cleaning liquid foams. In addition, since the inner nozzle 38 has a flat shape and is flexible, the inner nozzle 38 is vibrated by the discharge of the compressed air, and as a result, the cleaning liquid foams more effectively. Further, since the outer tube portion 30 of the fluid tube 14 is flexible enough to generate a pulsation in the fluid passing through the inside, the rinsing by the outer tube portion 30 further foams the cleaning liquid. Will be. As a result, a sufficiently foamed cream-like cleaning liquid is discharged from the external nozzle 33 of the opening / closing gun 15 to a cleaning target such as an air conditioner.
[0027]
Here, if necessary, by adjusting the opening / closing amount of the flow path in the fluid pipe 14 by the adjusting valve 40, the flow rate of the cleaning liquid with respect to the flow rate of the compressed air introduced into the fluid pipe 14 by the gas pipe 37 is adjusted. Thus, the state of foaming can be adjusted to a desired state.
[0028]
As described above, the cleaning liquid foamed in the form of cream stays on the object to be cleaned for a long time without flowing down, and effectively performs cleaning.
[0029]
On the other hand, when flushing the cleaning liquid, the cleaning liquid in the tank 12 is replaced with water. Then, as described above, when the operator operates the lever 32 to open the open / close gun 15, the water in the pressurized tank 12 is guided to the open / close gun 15 via the fluid pipe 14. It is ejected from the external nozzle 33 of the opening / closing gun 15.
[0030]
At this time, similarly to the above, the compressed air introduced into the tank 12 by the air compressor 13 is also blown out from the internal nozzle 38 of the gas pipe 37 provided at an intermediate position of the fluid pipe 14. Compressed air is introduced into the water flowing through the fluid pipe 14 by the ejection of the compressed air from the internal nozzle 38, and the water is formed into fine particles by the ejection of the compressed air. Moreover, since the inner nozzle 38 has a flat shape and is flexible, the inner nozzle 38 vibrates due to the discharge of the compressed air, and as a result, water is more effectively made into fine particles. Further, since the outer tube portion 30 of the fluid tube 14 is flexible enough to cause pulsation of the fluid passing through the inside, the pulsation by the outer tube portion 30 makes the water finer. It becomes a grain. Then, the water that has been made into such fine particles is jetted from the external nozzle 33 of the opening / closing gun 15 with pulsation by the external pipe portion 30. As a result, water particles intermittently hit an object to be cleaned such as an air conditioner. By such a water hammering effect, it is possible to wash away the cleaning liquid with a small amount of water and to remove dirt floated by the cleaning liquid.
[0031]
Here, if necessary, if the opening / closing amount of the fluid pipe 14 is adjusted by the adjusting valve 40, the flow rate of the water with respect to the flow rate of the compressed air introduced into the fluid pipe 14 by the gas pipe 37 is adjusted. The state of the grains can be adjusted to a desired state.
[0032]
In the above description, it is of course possible to directly wash with only water without using a washing liquid. Also in this case, the small amount of water can be sufficiently washed by the fine particles of the water to be jetted out and the pulsation by the external pipe part 30 as described above.
Further, in the above, if the inside of the tank 12 is emptied, only the compressed air can be ejected from the external nozzle 33 of the opening / closing gun 15 via the fluid pipe 14, and for example, drainage after washing with water can be performed.
[0033]
As described above, according to the present embodiment, a sufficiently bubbling cleaning liquid can be discharged from the opening / closing gun 15, so that cleaning efficiency can be greatly improved and energy saving can be improved. . That is, when the detergent is diluted with water to prepare the cleaning liquid, the cleaning liquid can be sufficiently foamed even if the dilution ratio is significantly increased (for example, 100 times).
[0034]
In addition, sufficiently finely divided water can be discharged from the opening / closing gun 15 together with the pulsation, and the cleaning can be effectively performed using a small amount of water. Can be increased.
[0035]
In addition, the air compressor 13 also serves as a pressurizing source for the cleaning liquid or water and a source for supplying compressed air into the fluid pipe 14. Therefore, cost can be reduced.
[0036]
【The invention's effect】
As described above in detail, according to the first aspect of the invention, for example, by putting the cleaning liquid into the tank and opening the opening / closing gun, the pressurized cleaning liquid is supplied from the tank to the opening / closing gun via the fluid pipe. When the cleaning liquid is ejected from the opening / closing gun, gas is introduced into the cleaning liquid from an internal nozzle of a gas pipe provided at an intermediate position of the fluid pipe, and the cleaning liquid is foamed. In addition, since the internal nozzle has flexibility, the internal nozzle vibrates due to discharge of gas, and as a result, the cleaning liquid is foamed more effectively. In addition, since the fluid pipe has flexibility, the cleaning liquid pulsates, and from this point, the cleaning liquid is more effectively foamed. Therefore, by sufficiently bubbling the cleaning liquid, the cleaning efficiency can be improved, and the energy saving can be improved.
[0037]
Also, for example, by putting water into a tank and opening the opening / closing gun, pressurized water is guided from the inside of the tank to the opening / closing gun via the fluid pipe and ejected from the opening / closing gun. The gas is introduced into the water from the internal nozzle of the provided gas pipe to make the water particles fine. In addition, since the internal nozzle has flexibility, the internal nozzle vibrates due to discharge of gas, and as a result, water is more effectively made into fine particles. In addition, since the fluid pipe has flexibility, pulsation can be generated in water and can be ejected with the pulsation. Therefore, the water can be made into sufficiently small particles and the hammering effect due to the pulsation at the time of jetting can effectively perform cleaning with a small amount of water, thereby improving cleaning efficiency and improving energy saving. .
[0038]
According to the second aspect of the present invention, the gas introduced into the tank for pressurizing the cleaning liquid or the water by the pressurizing means is introduced into the fluid pipe by the gas pipe. The source is also used as a gas supply source into the fluid pipe. Therefore, cost can be reduced.
[0039]
According to the invention according to claim 3, when the opening / closing amount of the fluid pipe is adjusted by the adjustment valve, the flow rate of the cleaning liquid or water with respect to the flow rate of the gas introduced into the fluid pipe by the gas pipe is adjusted. Can adjust the state of bubbling, and in the case of water, can adjust the size of grains.
