Description

[Technical field]

[0001] To provide a vacuum cleaner having a dry wiping cloth holder near a suction port for fixing a dry wiping cloth so that the dry wiping cloth is not drawn into the vacuum cleaner when dust adhering to the dry wiping cloth after wiping off dust is sucked and removed in a suction tube of the vacuum cleaner. [Background technology]

[0002] Conventional vacuum cleaners are primarily intended for cleaning floors, and it is difficult to clean the surfaces of furniture, shelves, precision equipment, etc. Therefore, some vacuum cleaners are equipped with an auxiliary tool for cleaning, such as an attachment such as a brush attached to the suction port. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2000-175856 A [Patent Document 2] Patent No. 3752475 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the size of the vacuum cleaner makes it difficult to clean the surfaces of furniture, shelves, precision equipment, etc. with an attachment such as a brush attached to the suction port of the vacuum cleaner, and therefore it is difficult to perform a thorough finish.

[0005] In Patent Document 1, a duster for removing dust is provided separately from the vacuum cleaner, but the dust removed by the duster floats up and eventually settles back into the surrounding area.

[0006] In Patent Document 2, a dust cloth is provided in addition to the vacuum cleaner, but dust adhering to the dust cloth must be washed off with water separately.

[0007] The present invention has been proposed in consideration of the above circumstances, and involves removing dust adhering to furniture, shelves, precision equipment, etc. with a dry wiping cloth, and then sucking and removing the dust adhering to the dry wiping cloth using turbulent air currents generated in the suction tube of a vacuum cleaner, thereby enabling the dry wiping cloth to be cleaned of dust on the spot after wiping and reused without having to blow the dust into the surrounding area or wash the adhering dust off with water separately.

[0008] When the dry wiping cloth is exposed to turbulent air currents in the suction tube, it is necessary to secure the dry wiping cloth so that it is not sucked into the vacuum cleaner body. It is possible to hold one end of the dry wiping cloth by hand, but there is a risk that the strong suction force will cause the dry wiping cloth to be sucked into the vacuum cleaner body, and there is also a risk of injuring the fingers holding the dry wiping cloth.

[0009] To provide a vacuum cleaner equipped with a dry wiping cloth hanger capable of supplementing the cleaning of furniture, shelves, precision equipment, etc., where it is difficult to use a vacuum cleaner, by using a dry wiping cloth, safely and surely sucking and removing dust adhering to the dry wiping cloth by a suction tube of the vacuum cleaner, and cleaning while regenerating the dry wiping cloth, an attachment for the vacuum cleaner, and a method for removing dust adhering to the dry wiping cloth. [Means for solving the problem]

[0010] The vacuum cleaner of the present invention has a dry wiping cloth hanging protrusion around the suction port, and by hooking a hook hole provided at one end of the dry wiping cloth onto the dry wiping cloth hanging protrusion, the dry wiping cloth vibrates in the turbulent air current within the suction tube against the pulling force caused by the suction of the vacuum cleaner during suction, thereby removing dust adhering to the dry wiping cloth.

[0011] The vacuum cleaner of the present invention has a dry wiping cloth hanging protrusion around the suction port, and the tip of the protrusion is bent in the opposite direction to the direction in which the dry wiping cloth is pulled by the suction of the vacuum cleaner. By hooking a hook hole provided at one end of the dry wiping cloth onto the dry wiping cloth hanging protrusion, the dry wiping cloth vibrates in the turbulent air current within the suction tube against the pulling force caused by the suction of the vacuum cleaner during suction, and dust adhering to the dry wiping cloth is removed.

[0012] The vacuum cleaner of the present invention has a dry wiping cloth hanging protrusion around the suction port, the tip of which is bent, and a hinge at the base of the protrusion. When the hinge is rotated, the dry wiping cloth hanging protrusion protrudes in the opposite direction to suction at the center of the suction port of the vacuum cleaner, and a hook hole at one end of the dry wiping cloth is hooked onto the dry wiping cloth hanging protrusion, so that the dry wiping cloth vibrates in the turbulent air inside the suction tube against the pulling force caused by the suction of the vacuum cleaner during suction, removing dust adhering to the dry wiping cloth.

[0013] The vacuum cleaner of the present invention has a dry wiping cloth hanging clip around the suction port, and by gripping one end of the dry wiping cloth, the dry wiping cloth vibrates in the turbulent air current against the pulling force caused by the suction of the vacuum cleaner during suction, thereby removing dust adhering to the dry wiping cloth.

[0014] The vacuum cleaner attachment of the present invention is connected to the suction port of the vacuum cleaner and has a dry wiping cloth hanging protrusion around the attachment suction port. By hooking a hook hole provided at one end of the dry wiping cloth onto the dry wiping cloth hanging protrusion, the dry wiping cloth vibrates in the turbulent air current within the suction tube against the pulling force caused by the suction of the vacuum cleaner during suction, thereby removing dust adhering to the dry wiping cloth.

[0015] The vacuum cleaner attachment of the present invention is connected to the suction port of the vacuum cleaner and has a dry wiping cloth hanging protrusion around the attachment suction port, with the tip of the protrusion bent in the opposite direction to the direction in which the dry wiping cloth is pulled by the suction of the vacuum cleaner. By hooking a hook hole provided at one end of the dry wiping cloth onto the dry wiping cloth hanging protrusion, the dry wiping cloth vibrates in the turbulent air current within the suction tube against the pulling force caused by the suction of the vacuum cleaner during suction, removing dust adhering to the dry wiping cloth.

[0016] The vacuum cleaner attachment of the present invention is connected to the suction port of the vacuum cleaner, has a dry wiping cloth hanging protrusion around the attachment suction port with the tip of the protrusion bent, and further has a hinge at the base of the protrusion, which can be rotated so that the dry wiping cloth hanging protrusion protrudes in the opposite direction to suction at the centre of the suction port of the vacuum cleaner, and a hook hole provided at one end of the dry wiping cloth is hooked onto the dry wiping cloth hanging protrusion, so that the dry wiping cloth vibrates in the turbulent air currents inside the suction tube against the pulling force caused by the suction of the vacuum cleaner during suction, removing dust adhering to the dry wiping cloth.

[0017] The vacuum cleaner attachment of the present invention is connected to the suction port of the vacuum cleaner, has a dry wiping cloth hanging clip around the attachment suction port, and by gripping one end of the dry wiping cloth, the dry wiping cloth vibrates in the turbulent air current within the suction tube against the pulling force caused by the suction of the vacuum cleaner during suction, thereby removing dust adhering to the dry wiping cloth.

[0018] The method of the present invention for removing dust adhering to a dry wiping cloth involves first securing one end of the dry wiping cloth to a dry wiping cloth hanging protrusion or dry wiping cloth hanging clip provided around the suction port of a vacuum cleaner, or around the suction port of an attachment connected to the suction port of the vacuum cleaner, then driving the vacuum cleaner body to suck the dry wiping cloth gradually into the suction tube from the opposite end where it is not secured, exposing it to the airflow in the suction tube and removing the dust, and then stopping the suction drive of the vacuum cleaner body and removing the dry wiping cloth from which the dust has been removed. Effect of the Invention

[0019] According to the present invention, when cleaning with a vacuum cleaner, dust adhering to the surfaces of furniture, shelves, precision equipment, etc. is wiped off with a dry wiping cloth, and the dry wiping cloth with the dust adhering thereto can be easily and quickly regenerated for dust removal, so that the dry wiping cloth can be reused many times during cleaning, and cleaning can proceed efficiently and neatly.

[0021] An example of a conventional vacuum cleaner 1 is shown in Fig. 1. It is composed of a vacuum cleaner main body 2, a hose 3, a hand suction tube 4, an extension suction tube 5, and a floor nozzle 6. The hose 3 is connected to the vacuum cleaner main body 2, the hand suction tube 4 is normally connected to the hose 3 so as to be freely rotatable, the extension suction tube 5 is connected to the hand suction tube 4, and the floor nozzle 6 is connected to the extension suction tube 5. When a power switch (not shown) located on the hand suction tube 4 is turned on, the suction machine (not shown) of the vacuum cleaner main body 2 is driven to suck up dust from the floor nozzle 6 via the hose 3, the hand suction tube 4, and the extension suction tube 5 for cleaning.

[0022] An embodiment of a vacuum cleaner having a dry wiping cloth holder near the suction port of the present invention will be described with reference to the drawings. In the embodiment of the present invention, components having the same configurations and functions as those of the conventional vacuum cleaner 1 shown and described in Figure 1 are referred to by the same reference numerals, and detailed description thereof will be omitted.

[0023] An example of a dry wiping cloth is shown in Figure 2. The dry wiping cloth 11 is made of cotton, wool, synthetic fiber, or the like, depending on the object to be wiped, and is preferably thin so that it can be easily attached to the hand suction tube 4. The dry wiping cloth 11 has a hook hole 12 at one end so that it can be easily hung on the projection.

[0024] A first embodiment of the present invention is shown in FIGS. A protrusion 13 for hanging a dry wiping cloth is provided around the suction port 7 of the hand suction tube 4. In this embodiment, the dry wiping cloth hanging projection 13 is attached to the outside of the periphery of the suction port 7, but it is also possible to attach it to the inside of the hand suction tube 4.

[0025] The hook hole 12 opened at one end of the dry wiping cloth 11 is hooked onto the dry wiping cloth hooking projection 13 shown in Fig. 4a. After the surface of furniture, a shelf, precision equipment, etc. is dry-wiped and cleaned with the dry wiping cloth 11, as shown in Fig. 4b, the hook hole 12 of the dry wiping cloth 11 with dust attached thereto is hooked onto the dry wiping cloth hooking projection 13, and the dust is sucked and removed by the hand suction tube 4. The dry wiping cloth 11 is subjected to a strong turbulent air current, for example, in the direction of the arrow, in the hand suction tube 4. In the suction tube, particularly in the area where the dry wiping cloth 11 is located, the dry wiping cloth 11 is exposed to the turbulent air current and vibrates, and the dust attached to the dry wiping cloth 11 is removed, making it possible to use it again for dry wiping and cleaning.

[0026] A second embodiment of the present invention is shown in FIG. A dry wiping cloth hanging projection 14 is provided around the suction port 7 of the hand suction tube 4. The tip of the dry wiping cloth hanging projection 14 is bent in the opposite direction to the direction in which the dry wiping cloth 11 is pulled by the suction of the vacuum cleaner body 2, and by hanging a hanging hole 12 opened at one end of the dry wiping cloth 11 on the dry wiping cloth hanging projection 14, the dry wiping cloth 11 vibrates in the turbulent air current within the suction tube 4 against the pulling force due to the suction of the vacuum cleaner body 2 that it receives during suction, and dust attached to the dry wiping cloth 11 is removed. In this embodiment, the dry wiping cloth hanging projection 14 is attached to the outside of the suction port 7, but it can also be attached to the inside of the hand suction tube 4. In that case, the tip of the dry wiping cloth hanging projection 14 is bent in the opposite direction to the direction in which the dry wiping cloth 11 is pulled by the suction of the vacuum cleaner body 2, so the tip orientation is opposite to that in FIG. In this embodiment, the dry wiping cloth 11 can be secured more reliably than in the first embodiment. The behavior of the dry wiping cloth during suction by the vacuum cleaner main body 2 is the same as in the first embodiment, and therefore will not be described.

[0027] A third embodiment of the present invention is shown in FIG. A protrusion 15 for hanging a dry wiping cloth is provided around the suction port 7 of the hand suction tube 4. The dry wiping cloth hanging projection 15 has a hinge 16. When the dry wiping cloth 11 is sucked in, the hinge 16 rotates 180 degrees from Fig. 6a to Fig. 6b as shown by the arrow, causing the tip of the dry wiping cloth hanging projection 15 to stand in the center of the suction port 7 in the opposite direction to the direction in which the dry wiping cloth 11 is pulled by suction. As shown in Fig. 6c, the hook hole 12 opened at one end of the dry wiping cloth 11 is hooked onto the dry wiping cloth hanging projection 15, thereby removing dust attached to the dry wiping cloth 11 in the suction tube 4 against the pulling force caused by the suction of the vacuum cleaner body 2 that the dry wiping cloth 11 receives during suction. According to this embodiment, the dry wiping cloth 11 is reliably exposed to the airflow in the suction tube 4 and vibrates with the turbulent airflow flowing, for example, as shown by the arrow, making it easier to remove dust adhering to the dry wiping cloth 11. Also, unlike the first and second embodiments, the hook hole 12 of the dry wiping cloth 11 is fixed to the center of the diameter of the suction tube 4, so that the airflow flowing in from the suction port 7 is not biased and tends to generate turbulent airflow, and dust adhering to the dry wiping cloth 11 can be removed quickly. If the tip of the dry wiping cloth hooking projection 15 standing in the center of the suction port 7 is made into a cross shape and the position where the hook hole 12 is fixed is moved away from the suction port 7, the bias of the airflow flowing in from the suction port 7 is further improved, turbulent airflow is easily generated, and the dust removal efficiency of the dry wiping cloth 11 is increased.

[0028] A fourth embodiment of the present invention is shown in FIG. As shown in FIG. 7a, a clip 17 for hanging a dry wiping cloth is provided around the suction port 7 of the handheld suction tube 4. The tip of the dry wiping cloth clip 17 presses against the outer circumference of the hand suction tube 4 by a spring (not shown), and it is possible to grasp and fix one end of the dry wiping cloth 11. The hook hole 12 opened at one end of the dry wiping cloth 11 is not particularly necessary, but if the hook hole 12 is hooked onto the dry wiping cloth clip 17 (not shown), the fixation of one end of the dry wiping cloth 11 becomes more reliable. As shown in Fig. 7b, the dry wiping cloth 11 whose one end is grasped by the dry wiping cloth clip 17 vibrates in the turbulent air currents in the same manner as in the first embodiment, resisting the pulling force due to the suction of the vacuum cleaner body 2 received within the suction tube 4 during suction, and removes dust attached to the dry wiping cloth 11. According to this embodiment, the dry wiping cloth 11 does not need to be provided with a hanging hole 12 at one end, and can be easily fixed.

[0029] A fifth embodiment of the present invention is shown in FIG. An attachment dry wiping cloth hanging protrusion 113 is provided around the attachment suction port 107 of the attachment suction tube 104. The attachment connection tube 108 is connected to the suction port 7 of the hand suction tube 4. It is preferable that the attachment suction port 107 be connectable to the extension suction tube 5.

[0030] The hook hole 12 opened at one end of the dry wiping cloth 11 can be hooked onto the attachment dry wiping cloth hooking projection 113. After the surface of furniture, shelves, precision equipment, etc. is dry wiped and cleaned with the dry wiping cloth 11, the hook hole 12 of the dry wiping cloth 11 with dust attached thereto is hooked onto the attachment dry wiping cloth hooking projection 113, and the dust is sucked through the attachment suction tube 104 by the hand suction tube 4 to remove the attached dust. The dry wiping cloth 11 is subjected to strong turbulent airflow in the attachment suction tube 104 and the hand suction tube 4, as in FIG. 4b. In the attachment suction tube 104 and the hand suction tube 4, particularly in the area where the dry wiping cloth 11 is located, the dry wiping cloth 11 is exposed to the turbulent airflow and vibrates, and the dust attached to the dry wiping cloth 11 is removed, making it possible to use it again for dry wiping and cleaning.

[0031] A fifth embodiment of the present invention having a different shape is shown in FIG. 8-2. The attachment suction tube 104 is shorter than that of the embodiment in Fig. 8. Since it is difficult to connect to the extension suction tube 5, it is preferable to use it only when removing dust from the dry wiping cloth 11 and to remove it when connecting the extension suction tube 5 to the handheld suction tube 4. The dust removal process for the dry wiping cloth 11 is the same as that of the embodiment in Fig. 8, and will not be described here. The slightly narrow tip diameter of the attachment connection tube 108 makes it easy to connect it to the handheld suction tube 4, and also enables it to be connected to other suction tubes with different diameters. This is desirably also applied to the embodiment of FIG.

[0032] A sixth embodiment of the present invention is shown in FIG. An attachment dry wiping cloth hanging protrusion 114 is provided around the attachment suction port 107 of the attachment suction tube 104. The attachment connection tube 108 is connected to the suction port 7 of the hand suction tube 4. It is preferable that the attachment suction port 107 be connectable to the extension suction tube 5.

[0033] The tip of the attachment dry wiping cloth hanging projection 114 is bent in the opposite direction to the direction in which the dry wiping cloth 11 is pulled by the suction of the vacuum cleaner body 2, and by hanging the hanging hole 12 opened at one end of the dry wiping cloth 11 on the attachment dry wiping cloth hanging projection 114, the dry wiping cloth 11 vibrates in the turbulent air current within the suction tube 4 against the pulling force caused by the suction of the vacuum cleaner body 2 that it receives during suction, thereby removing dust adhering to the dry wiping cloth 11. In this embodiment, the dry wiping cloth hanging projection 114 is attached to the outside around the attachment suction port 107, but it is also possible to attach it to the inside of the attachment suction tube 104. In that case, the tip of the attachment dry wiping cloth hanging projection 114 is bent in the opposite direction to the direction in which the dry wiping cloth 11 is pulled by the suction of the vacuum cleaner body 2, so the tip faces in the opposite direction to that in FIG. This embodiment can secure the dry wiping cloth 11 more reliably than the fifth embodiment.

[0034] A sixth embodiment of the present invention having a different shape is shown in FIG. 9-2. The attachment suction tube 104 is shorter than that of the embodiment in Fig. 9. Since it is difficult to connect to the extension suction tube 5, it is preferable to use it only when removing dust from the dry wiping cloth 11 and to remove it when connecting the extension suction tube 5 to the handheld suction tube 4. The dust removal process for the dry wiping cloth 11 is the same as that of the embodiment in Fig. 9, and will not be described here. The slightly narrow tip diameter of the attachment connection tube 108 makes it easy to connect it to the handheld suction tube 4, and also enables it to be connected to other suction tubes with different diameters. This is desirably also applied to the embodiment of FIG.

[0035] A seventh embodiment of the present invention is shown in FIG. An attachment dry wiping cloth hanging protrusion 115 is provided around the attachment suction port 107 of the attachment suction tube 104. The attachment connection tube 108 is connected to the suction port 7 of the hand suction tube 4. It is preferable that the attachment suction port 107 be connectable to the extension suction tube 5.

[0036] The attachment dry wiping cloth hanging projection 115 has an attachment hinge 116. When the dry wiping cloth 11 is sucked in, the attachment hinge 116 rotates 180 degrees from Fig. 10a to Fig. 10b as shown by the arrow, causing the tip of the attachment dry wiping cloth hanging projection 115 to stand in the opposite direction to the direction in which the dry wiping cloth 11 is pulled by suction at the center of the attachment suction port 107. As in Fig. 6c, the attachment dry wiping cloth hanging projection 115 is hooked into the hook hole 12 opened at one end of the dry wiping cloth 11, thereby removing dust attached to the dry wiping cloth 11 in the attachment suction tube 104 and the hand suction tube 4 against the pulling force due to the suction of the vacuum cleaner body 2 that the dry wiping cloth 11 receives during suction. According to this embodiment, the dry wiping cloth 11 is reliably exposed to the airflow in the attachment suction tube 104 and the hand suction tube 4, and vibrates with the turbulent airflow as in FIG. 6c, making it easier to remove dust attached to the dry wiping cloth 11. Also, unlike the fifth and sixth embodiments, the hook hole 12 of the dry wiping cloth 11 is fixed to the center of the tube diameter of the attachment suction tube 104, so that the airflow flowing in from the attachment suction port 107 is not biased and tends to generate turbulent airflow, and dust attached to the dry wiping cloth 11 can be removed quickly. If the tip of the dry wiping cloth hanging protrusion 115 standing in the center of the attachment suction port 107 is made into a cross shape and the position where the hook hole 12 is fixed is moved away from the attachment suction port 107, the bias of the airflow flowing in from the attachment suction port 107 is further improved, making it easier to generate turbulent airflow, and the dust removal efficiency of the dry wiping cloth 11 is increased.

[0037] A seventh embodiment of the present invention having a different shape is shown in FIG. 10-2. The attachment suction tube 104 is shorter than that of the embodiment in Fig. 10. Since it is difficult to connect to the extension suction tube 5, it is preferable to use it only when removing dust from the dry wiping cloth 11 and to remove it when connecting the extension suction tube 5 to the handheld suction tube 4. The dust removal process for the dry wiping cloth 11 is the same as that of the embodiment in Fig. 10, and will not be described here. The tip diameter of the attachment connection tube 108 is slightly narrow, which makes it easy to connect it to the hand suction tube 4 and also enables it to be connected to other suction tubes with different diameters. This is desirably applied to the embodiment of FIG.

[0038] An eighth embodiment of the present invention is shown in FIG. An attachment dry wiping cloth hanging clip 117 is provided around the attachment suction port 107 of the attachment suction tube 104. The attachment connection tube 108 is connected to the suction port 7 of the hand suction tube 4. It is preferable that the attachment suction port 107 be connectable to the extension suction tube 5.

[0039] The tip of the attachment dry wiping cloth hanging clip 117 presses against the outer circumference of the attachment suction tube 104 by a spring (not shown), and it is possible to grip and fix one end of the dry wiping cloth 11. The hook hole 12 opened at one end of the dry wiping cloth 11 is not particularly necessary, but if the hook hole 12 is hooked onto the attachment dry wiping cloth hanging clip 117 (not shown), the fixation of one end of the dry wiping cloth 11 will be more secure. The dry wiping cloth 11, whose one end is gripped by the attachment dry wiping cloth hanging clip 117, vibrates in the turbulent air currents as in the first embodiment, against the pulling force due to the suction of the vacuum cleaner body 2 received within the attachment suction tube 104 and the suction tube 4 during suction, and removes dust attached to the dry wiping cloth 11. According to this embodiment, the dry wiping cloth 11 does not need to be provided with a hanging hole 12 at one end, and can be easily fixed.

[0040] An eighth embodiment of the present invention having a different shape is shown in FIG. 11-2. The attachment suction tube 104 is shorter than that of the embodiment in Fig. 11. Since it is difficult to connect to the extension suction tube 5, it is preferable to use it only when removing dust from the dry wiping cloth 11 and to remove it when connecting the extension suction tube 5 to the handheld suction tube 4. The dust removal process for the dry wiping cloth 11 is the same as that of the embodiment in Fig. 11, and will not be described here. The tip diameter of the attachment connection tube 108 is slightly narrow, which makes it easy to connect it to the hand suction tube 4 and also enables it to be connected to other suction tubes with different diameters. This is desirably applied to the embodiment of FIG.

[0041] The method of removing dust adhering to the dry wiping cloth of the present invention involves turning off the power switch (not shown) arranged on the hand suction tube 4, removing the extension suction tube 5 from the hand suction tube 4, and securing the hook hole 12 of the dry wiping cloth 11 by hooking it to the dry wiping cloth hanging protrusions 13, 14, 15 or the dry wiping cloth hanging clip 17. However, in the case of the dry wiping cloth hanging clip 17, a dry wiping cloth 11 without the hook hole 12 can also be used. The power switch (not shown) arranged on the hand suction tube 4 is turned on, and the dry wiping cloth 11 is gradually sucked into the hand suction tube 4 from the suction port 7 of the hand suction tube 4 from the opposite end not secured, and exposed to the airflow of the hand suction tube 4 to remove dust. When the attachment suction tube 104 is used, the attachment suction tube 104 is connected to the hand suction tube 4, and the hanging hole 12 of the dry wiping cloth 11 is secured by hanging it on the attachment dry wiping cloth hanging protrusions 113, 114, 115 or the attachment dry wiping cloth hanging clip 117 in the same manner as described above. However, in the case of the attachment dry wiping cloth hanging clip 117, a dry wiping cloth 11 without a hanging hole 12 can also be used. The power switch (not shown) arranged on the hand suction tube 4 is turned on, and the dry wiping cloth 11 is gradually sucked into the hand suction tube 4 from the attachment suction port 107 of the attachment suction tube 104 from the opposite end where the dry wiping cloth 11 is not secured, and exposed to the air flow of the hand suction tube 4 to remove dust.

[0042] In order to investigate whether dust adhering to a dry wiping cloth can be removed by utilizing the turbulent air currents generated in the suction tube of a vacuum cleaner, the following vacuum cleaner was used. Panasonic vacuum cleaner (household) Product number MC-PK17A Power consumption: 1150W~approx. 200W (during operation) Suction power: 580~60W Suction port inner diameter Φ42mm When the dry wiping cloth is attached with one end fixed inside the suction tube of a vacuum cleaner and the vacuum cleaner is operated for suction, the airflow around the dry wiping cloth inside the suction tube fluctuates violently, and the dry wiping cloth is exposed to the turbulent airflow and vibrates, shaking off the dust attached to the dry wiping cloth. When the dry wiping cloth with dust attached beforehand is exposed to this turbulent airflow for 30 seconds and then removed, the dust attached to the cloth is visually almost completely removed.

[0043] The wind speed near the suction port of the vacuum cleaner under no load exceeded 20m / sec. This is the same strong wind as the wind outside a car traveling at over 70km / hr when there is no wind, and if a dry wiping cloth is exposed to this environment with one end fixed, the cloth will vibrate violently due to the turbulent air. Canister-type vacuum cleaners available on the market generally have a suction power of around 600W, and it has been confirmed that even among stick-type vacuum cleaners, there are some that have a wind speed near the suction port of over 20m / sec when unloaded.

[0044] The time required for dust removal varies depending on the suction power of the vacuum cleaner 1 and the inner diameter of the suction port of the handheld suction tube 4, but if the suction power is up to 600 W and the inner diameter of the suction port is Φ42 mm, dust removal is sufficient in a processing time of about 30 seconds. Stick-type vacuum cleaners generally have low suction power, but some manufacturers have vacuum cleaners with high suction power, and the airflow near the suction port is 20 m / sec or more. In that case, dust removal is sufficient in a processing time of about 30 seconds, but for vacuum cleaners with an airflow near the suction port of about 10 m / sec, it is desirable to perform dust removal for several minutes.

[0045] After the dust removal process, the power switch (not shown) located on the hand suction tube 4 is turned off, the suction drive of the vacuum cleaner body 2 is stopped, and the dry wiping cloth 11 from which the dust has been removed is removed, and cleaning can be continued again by connecting the extension suction tube 5 to the hand suction tube 4, or connecting the extension suction tube 5 to the attachment suction tube 104 while leaving the attachment suction tube 104 connected to the hand suction tube 4. The dry wiping cloth 11 from which the dust has been removed does not need to be washed with water like a dustcloth, and it can be used again and again after dust removal even during cleaning.

[0046] Although the present invention has been described with reference to an embodiment in which a dry wiping cloth hook protrusion and a dry wiping cloth hook clip are used to hook one end of the dry wiping cloth, it is also possible to use a dry wiping cloth that has a function of being hooked onto the dry wiping cloth hook protrusion instead of a hook hole.

[0047] While the present invention has been described with reference to preferred embodiments thereof, it is to be understood that the present invention is not limited to the exact construction and operation shown and described, and that various modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
