Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention relates to a carpet cleaning device using a pin that vibrates up and down.More specifically, the present invention relates to a carpet cleaning device that uses a pin that vibrates up and down. This is a device that applies chemicals or detergents such as

0002

[Prior Art] Carpet cleaning involves spraying a cleaning solution onto the carpet, then pressing a hard brush rotated by a motor or the like against the carpet to scrub the carpet, followed by washing with water and drying.

Another method is to spray a cleaning solution onto the carpet, allow the solution to permeate the carpet for a while, then suck it up, wash it with water, and dry it.

0004

[Problem to be solved by the invention] However, in the former method, since the brush is rotated to scrub the carpet,
The hair on the carpet comes out very easily, and the hair and threads of the carpet may become loose.

[0005] Depending on the type of hair, several percent to more than ten percent of the hair may fall out. Also, since the hair of the carpet stands up against the base material, it is difficult to get dirt deep inside the hair. Furthermore, if the amount of cleaning solution sprayed is large, the dirty solution will re-adhere and create a dirt pattern.

[0006] The latter method also has the disadvantage that severe stains are difficult to remove.

Furthermore, both methods require a great deal of effort and time for washing and drying steps.

[0008] Therefore, the present invention is a carpet cleaning device that can fix loose hairs and threads on a carpet, regenerate and repair them, and also remove dirt from deep inside the carpet hairs, dry quickly, etc. It is an object of the present invention to provide a carpet cleaning device that also has a coating function that enables the coating of agents and medicines to the deepest parts of the hairs of the carpet.

[0009]

[Means for Solving the Problems] The present invention provides a vibration driving body in the main body of the device, a substantially horizontal diaphragm that vibrates up and down is suspended from the vibration driving body, and a large number of pins are protruded from the bottom surface of the diaphragm. do. Further, the large number of pins move in and out of the bottom plate of the device main body as the diaphragm moves up and down, and form a large number of small holes that can freely protrude from the bottom surface of the bottom plate of the device main body. In addition, the main body of the device is provided with appropriate wheels to support the main body of the device, and furthermore, a spout for a solution containing a coating agent such as a detergent, a chemical agent, or a drug is provided near the bottom plate of the device main body having the above-mentioned small holes. It is something.

[0010] Furthermore, a heater may be provided on the bottom plate of the main body of the above-mentioned apparatus itself or at a nearby location.

[0011] In some cases, a suction device for collecting dust is provided on one side of the apparatus main body of the above-mentioned apparatus, and the suction port thereof is provided on one side of the bottom plate of the apparatus main body or at a location adjacent to the apparatus main body.

0012

[Operation] When the vibration drive body of the present invention is operated, the diaphragm supported by the vibration drive body vibrates up and down. As a result, each of the many pins on the lower surface of the diaphragm passes through each small hole in the bottom plate of the apparatus main body, protrudes from the lower surface of the bottom plate of the apparatus main body, retracts, or vibrates up and down while remaining protruded.

When the main body of this device is placed on a carpet by rotating its wheels, each pin moves in and out of the fur of the carpet. Therefore, loose or frayed carpet hair or threads are pushed deep into the carpet or tangled by the vertical movement of these pins, and are fixed in their original state.

[0014] Moreover, the vertical movement of this pin causes the carpet to be struck in many places, thereby causing dust and dirt to float to the top surface of the carpet. At the same time, when the pins are moved up and down while dispensing an appropriate solution from the solution spout of the device main body, the solution adhering to these pins reaches deep into the hair or threads of the carpet.

[0015] Furthermore, the above device equipped with a heater is
The heater warms the top surface of the carpet into which the solution poured out from the solution spout has penetrated deep into the carpet, thereby promoting the drying of these solutions. Also, heating the carpet with a heater has the effect of sterilizing the carpet and killing insects such as dust mites inside the carpet. At this time, as mentioned above, by the vertical movement of the pin, dust mites and the like float to the top of the carpet, approach the heater, and are killed there.

Furthermore, if this device is equipped with a dust collection suction device, the dust and dirt floating on the top surface of the carpet can be sucked out from the suction port as described above.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings.

A motor 2 is fixed inside a box-shaped device main body 1, and a hole 3 is formed in the bottom plate 1a of the device main body 1 directly below the motor 2.
is wearing. A box-shaped pin protection cover 4 is provided on the lower surface of the bottom plate 1a so as to cover this hole 3.
A large number of small holes 5 are bored in the bottom plate. Further, the bottom plate of the pin protection cover 4 is inclined so as to become lower as it goes from right to left in FIG.

The lower end of a rod 6 whose upper end is connected to the drive shaft 2a of the motor 2 is passed through the hole 3, and the upper end of a vertical vibrating rod 7 is rotatably supported at the lower end by a shaft 8 to protect the pin. A substantially horizontal diaphragm 9 is fixed to the lower end of the vertical oscillating rod 7 inside the cover 4. Therefore, this diaphragm 9 is located inside the pin protection cover 4 and is supported by the drive shaft 2a of the motor 2 via the rod 6 and the vertical vibration rod 7. Further, an appropriate number of vibration stabilizing springs 10 are provided between the diaphragm 9 and the bottom plate 1a inside the pin protection cover 4. A large number of pins 11 are protruded from the lower surface of the diaphragm 9, and each pin 11 loosely passes through each small hole 5 of the pin protection cover 4.

[0020] Also, in the device main body 1, the motor 2
A power supply box 12 is installed next to the power supply box 1.
2, a power cord 13 provided outside the device main body 1 is introduced. Also, the power switch 1 of this power supply box 12
4 and a pilot lamp 15 are provided on the outer surface of the apparatus main body 1, respectively.

A tank 16 is provided in the upper part of the apparatus main body 1, and a liquid feeding pipe 17 is led out from the lower part of one side of the tank 16, the tip of which is inserted into the pin protection cover 4 to open the solution spout 17a. is forming. This liquid feed pipe 1
A switching valve 18 and an electromagnetic valve 19 are provided in the middle of the valve 7, respectively. The switching valve 19 is connected to the liquid feed pipe 17.
The drain pipe 20 can be opened/closed and switched to a drain pipe 20, and the tip of the drain pipe 20 is exposed on the outer surface of the main body 1 of the apparatus.

The tank 16 is also provided with a 100W heater 21 for warming the liquid in the tank 16 and a thermostat 22 for adjusting the temperature of the liquid.

A liquid inlet 23 with a lid is provided on the upper surface of the tank 16, and an opening 25 with a lid 24 is provided on the upper surface of the apparatus main body 1 facing the liquid inlet 23. Further, a liquid level indicator 26 indicating the liquid level in the tank 16 is provided on the outer surface of the apparatus main body 1. Furthermore, casters 27 that can be moved up and down are provided at the four corners of the bottom plate 1a of the main body 1, and a handle 28 protrudes from one side of the main body 1.

FIG. 5 shows details of the connecting portion between the drive shaft 2a of the motor 2 and the rod 6. An eccentric cam 30 is fixed to the outer circumference of the drive shaft 2a, and the eccentric cam 30 is inserted into a hole 31 bored at the upper end of the rod 6, and the inner circumference of this hole 31 and the eccentric cam 30 are
A ball bearing 32 is interposed between the outer circumference and the outer periphery of the ball bearing 32.

As a result, when the drive shaft 2a of the motor 2 is rotated, the eccentric cam 30 also rotates, and the upper end of the rod 6 rotates around the drive shaft 2a. However, since the lower end of the rod 6 is connected to the vertically vibrating rod 7 by the shaft 8, the vertically vibrating rod 7 can only move vertically. Therefore, the diaphragm 9 moves up and down, and each pin 11 moves up and down with respect to the pin protection cover 4.

In this manner, the pins 11 projecting downward from the numerous small holes 5 in the bottom plate of the pin protection cover 4 vibrate up and down. When the main body 1 of the device is placed on the carpet in this state, each pin 11 penetrates deep into the carpet's hair, hits the carpet, pushes the loose hairs and threads of the carpet deep into the carpet, and removes other hairs and threads. Tie it around the thread and secure it.

In this way, each pin 11 hits the carpet and penetrates deep into the wool and yarn, creating a protrusion between the pins 11 as shown in FIG. The impact location becomes a recess. By repeating this process, the protrusions become more protrusive and the recesses become more recessed, as shown by the dashed line in FIG. Then, along the rows of pins 11, uneven streaks are formed on the surface of the carpet in the form of ridges.

[0028] If, for example, a cleaning liquid is placed in the tank 16 and the liquid feed pipe 17 is opened using the switching valve 18, the electromagnetic valve 19 opens in conjunction with the rotation of the motor 2, and the liquid feed pipe 17 is opened from the tank 16. The cleaning liquid flows into the pipe 17 and flows out from the solution spout 17a at the tip of the liquid feed pipe 17. This cleaning liquid then flows onto the bottom plate of the pin protection cover 4.
It flows out along the outer periphery of each pin 11 from each small hole 5 that freely passes through each pin 11 that is moving up and down. At this time, since the bottom plate of the pin protection cover 4 is somewhat inclined, the cleaning liquid easily flows on the bottom plate from the right side to the left side in FIG.

In this way, the cleaning liquid adheres to each pin 11, and the pins 11 are vibrated up and down to move in and out of the hair and threads of the carpet, and this process is repeated, so that the cleaning liquid adheres to the depths of the carpet. do.

Furthermore, dirt and dust float to the top surface of the carpet due to the vertical vibration of the many pins 11. Therefore, dirt and dust can be easily sucked out using a separately prepared vacuum cleaner.

[0031] Also, since the cleaning liquid is heated to about 60° to 70°C by the heater 21 in the tank 16, it dries quickly after it adheres to the carpet.

[0032] Instead of the above-mentioned cleaning solution, a solution of a chemical agent such as an antistatic agent or a treatment agent may be placed in the tank 16 and applied to the carpet. Even if it is placed in the tank 16 and applied to a carpet, these chemical agents, treatment agents, agents, etc. will adhere to the deepest parts of the hair and threads of the carpet, as described above.

When the device is pushed by the handle 28, the casters 27 rotate and the device moves easily. Therefore, move this device gradually over the carpet,
Carpet restoration and repair, cleaning, and application of chemical agents, treatment agents, and chemicals can be performed.

[0034] The diameter of each pin 11 is 1.5 to 5 mm.
The length is approximately 30 mm to 50 mm. Further, 50 to 100 cc of cleaning liquid per square meter is sufficient, and the consumption amount is 1/5 to 1/10 of that of the conventional method. Further, the vertical movement of each pin 11 is from 10 cycles to 10 kilocycles, and there are cases where ultrasonic vibration is applied to each pin 11 itself to cause it to move vertically.

Further, as in the above-described embodiment, by heating the liquid in the tank 16 using the heater 21, it is possible to speed up the drying of the applied solution and increase the cleaning power. Also, when killing mites etc., the temperature of the solution should be 70° to 80°C.
It also has an insecticidal effect when raised to Additionally, alcohol may be added to the solution, which can increase the disinfection effect and speed up drying. This alcohol concentration is sufficiently effective at 6% or less.

Further, in the above-mentioned carpet refurbishment/repair, in order to entangle or lock the hair or threads of the carpet on the pins 11, it is conceivable to form the pins 11 into various shapes as shown in FIG.

The one shown in (a) is a cylindrical pin 11, the one shown in (b) has a plurality of annular grooves 34 provided on the outer periphery of the pin 11, and the one shown in (c) is a pin 11 with a tapered shape. The pin 11 is a cylindrical pin 11 with a flange-like piece 35 provided at the tip thereof,
In addition, the one shown in (d) has a spiral groove 36 on the outer periphery of the cylindrical pin.
It has been established.

In place of the above embodiment, a 500W heater 37 is provided in the bottom plate of the pin protection cover 4, as shown in FIG. The opening 39 may be provided at the rear of the pin protection cover 4 (on the left side in FIG. 8). In addition, the above heater 3
7 is not limited to the above location, but may be provided at any other appropriate location.

In this embodiment, a solution is applied to the carpet, and the applied solution is dried using a heater 37. Further, as described above, dirt, dust, etc. floating on the top surface of the carpet can be sucked out from the suction port 39 by the dust collecting suction device 38.

In the above embodiment, the motor 2, the rod 6,
Although the vertical vibration rod 7 causes the vibration plate 9 to vibrate vertically, instead of this, the vibration plate 9 may be vibrated vertically by a suitable drive device.

Further, in the above embodiment, the tip of the liquid feed pipe 17, that is, the solution spout 17a is located at the front inside the pin protection cover 4 (
Although it is provided on the right side in Fig. 1, this solution spout 17a
may be provided outside the front of the pin protection cover 4, or may be provided at a location close to the bottom plate of the main body of the device. Further, although the pin protection cover 4 is provided in the embodiment described above, it is also possible to provide the pin protection cover 4 without providing this and to directly drill the small hole 5 in the bottom plate 1a of the device main body 1 and allow the pin 11 to pass through it loosely.

[0042]

[Effects of the Invention] This invention uses a large number of pins to vibrate by vertical movement when cleaning a carpet, so the contact area with the carpet becomes large depending on the number of pins, the diameter and length of the pins, and the frequency of vibration. Processing capacity becomes extremely high. Moreover, the dust, dirt, dirt, etc. inside floats to the top surface of the carpet by hitting the deep part of the hair of the carpet with the pin, making it easy to remove the dirt and dirt. Moreover, since the pin moves up and down in the direction of the carpet hair, the contact length is long, making it easier to remove dirt, etc. In addition, since the solution such as the cleaning solution comes out from the solution spout near the pins, it tends to adhere to many pins, and the solution can be brought into contact with the deep parts of the hair and threads of the carpet, so the cleaning effect is extremely large. Also, unlike conventional rotating brushes, fibers do not get tangled and are pulled out.

Furthermore, by vertically vibrating a large number of pins in this way, loose hairs and threads can be pushed deep inside and entangled with other hairs and threads to be fixed, making it possible to repair the carpet. . If this can be done while supplying the fibers from which the carpet is made, the carpet can be regenerated more completely.

In addition, chemical agents such as antistatic agents, treatment agents, fungicides, antibacterial agents, and other agents can be penetrated deep into the carpet as described above, so they can be applied with the minimum amount of solution needed. It can be fully effective and therefore dry quickly.

[0045] Furthermore, in the case where a heater is provided, the applied solution can be immediately dried, so that the processing time can be shortened. Moreover, if the temperature is raised to about 70°C or higher, it will also have a sterilizing and insecticidal effect on the carpet.

[0046] In addition, those equipped with a dust collection suction device can automatically suck up dust floating on the top of the carpet by simply moving the device gradually over the carpet, making cleaning the carpet even easier. It can be simplified.
