Abstract

<P>PROBLEM TO BE SOLVED: To provide a rotating rotor which is excellent in assembling property, durability and scraping performance for dust and dirt. <P>SOLUTION: The vacuum cleaner includes a rotor 21 having at least one line of a supporting groove 23 in the outer peripheral longitudinal direction, and a cleaning element 22 which scrapes off dust and dirt. The cleaning element 22 is constituted of a flocked fabric 24 which has an approximately belt form, and is composed of a base material 24a and fibers 24b implanted on the base material, and a base section 25 which is fixed on both side ends of the flocked fabric 24. The flocked fabric 24 is folded approximately at the center with the base material 24a on the internal side, and both base sections 25 are fitted in the supporting groove 23. Then, an end part 22a in the radial direction of the cleaning element 22 is formed into a loop form. Since the flocked fabric 24 easily warps by a space section 26 which is formed between the base material 24a of the flocked fabric 24 and the rotor 21, even if a strong compressing force is applied to the flocked fabric 24 in cleaning, the rotating rotor 20 does not stop or the like. Additionally, since the fibers 24b of the flocked fabric 24 which are continuously arranged protrude outward, cleaning is uniformly performed. At the same time, the fibers are hard to be frayed, and in addition, the vacuum cleaner is excellent in scraping performance for dust and dirt. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a rotary rotor that removes dust while rotating, a floor suction tool for a vacuum cleaner using the same, an electric vacuum cleaner, and an air conditioner.

  As a conventional rotary rotor of this type, it is mounted on an air conditioner and consists of a rotor and a brush-like cleaning body planted in the longitudinal direction of the outer periphery of the rotor, and adheres to the surface of an air filter built in the air conditioner. There is one in which dust is removed by the cleaning body in a straightforward manner (see, for example, Patent Document 1).

  FIG. 12 is a longitudinal sectional view of an air conditioner equipped with the conventional rotary rotor described in Patent Document 1, and FIG. 13 is a perspective view of the rotary rotor.

  In FIG. 12, in the air conditioner main body 1, a heat exchanger 2, a suction port 3 for taking in indoor air, and a belt-shaped air filter provided between the heat exchanger 2 and the suction port 3. 4, a drive shaft 6 and a driven shaft 7 on which the air filter 4 is stretched, a servo motor 5 that rotationally drives the drive shaft 6, and a rotary rotor 8 that removes dust collected by the air filter 4. A driving means (not shown) for rotating the rotary rotor 8, an exhaust pipe 10 communicating with the suction port 3 and having the rotary rotor 8 and having a discharge port 9; There is provided a dust discharge fan 11 provided, and a fan 13 that sucks indoor air from the suction port 3 and blows out heat-exchanged air from the blowout port 12 through the heat exchanger 2 into the room.

  As shown in FIG. 13, the rotary rotor 8 is composed of a rotatable rotor 8a made of resin and a brush-like cleaning body 8b that is linearly planted in the longitudinal direction of the outer periphery of the rotor 8a.

  Operations and effects of the conventional rotary rotor and air conditioner having the above-described configuration are as follows.

  When the air conditioner main body 1 is in a cooling operation, for example, indoor air flows from the inlet 3 by the fan 13, passes through the air filter 4, reaches the heat exchanger 2, and is cooled there. Is blown out into the room. Dust contained in the indoor air to be sucked is collected by the air filter 4 and deposited on the surface of the filter 4. If dust accumulates on the surface of the air filter 4, the air pressure loss of air increases and the heat exchange efficiency decreases. Therefore, the dust on the air filter 4 can be removed periodically or as necessary. Driving is required.

  In the dust removal operation, the servo motor 5 is operated to rotate the drive shaft 6 to continuously move the belt-like filter 4, while the rotary rotor 8 is rotated and the dust discharge fan 11 is operated. Thus, the dust on the air filter 4 is scraped by the cleaning body 8b of the rotary rotor 8, and the scraped dust is sucked by the dust discharge fan 11 and discharged from the discharge port 9 to the outside. ing.

  However, since the rotary rotor 8 disclosed in Patent Document 1 is configured by flocking the cleaning body 8b on the rotor 8a made of resin or the like, the manufacturing cost is high and the cleaning body 8b is continuously formed. As a result, there was a problem that cleaning could not be performed uniformly.

  As a solution to solve this problem, the usage is for a vacuum cleaner, but as shown in FIG. 14, the rotary rotor 15 is wound around a cylindrical rotor 15a and an outer peripheral surface of the rotor 15a. There is what is comprised with the blanket 15b (for example, refer patent document 2).

Further, as shown in FIG. 15, the rotary rotor 16 is constituted by a rotor 17 having a plurality of spiral support grooves 17 a in the outer peripheral longitudinal direction and a cleaning body 18, and the cleaning body 18 is formed by a long fiber bundle. Is formed of a band plate 18a having a predetermined width formed by bending in a meandering manner, and a string-like attachment member 18b fixed to both edges in the longitudinal direction of the band plate 18a. Is folded around the center in the width direction, and the respective attachment members 18b at both ends are inserted and fixed in the support grooves 17a provided in the rotor 17, and the free end 19 of the cleaning body 18 is formed in a loop shape. (For example, refer to Patent Document 3).
JP-A-6-74521 JP-A-8-56875 JP 2002-00517 A

  In the rotary rotor 15 described in Patent Document 2, since the entire outer peripheral surface of the rotor 15a on the cylinder is covered with the raised cloth 15b, the tip portion of the raised cloth 15b continuously contacts the surface to be cleaned. Although uniform cleaning is possible, since the raised cloth 15b simultaneously contacts the surface to be cleaned over the entire width, the sliding resistance between the raised cloth 15b and the surface to be cleaned increases. When the motor is rotated by a motor or the like to remove dust efficiently, there are problems such as the rotation of the rotary rotor 15 being stopped during cleaning, or the motor being overloaded and burning the motor. Note that the sliding resistance between the raised cloth 15b and the surface to be cleaned can be reduced by making the fibers constituting the raised cloth 15b longer or thinner to weaken the fibers. Then, the dust scraping performance on the surface to be cleaned is lowered, which is not practical.

  Moreover, since the rotation rotor described in the said patent document 3 can be bent freely in the center part of the cleaning body 18 and the free end 19 can be bent freely, when cleaning the surface to be cleaned Even if an excessive force is applied to the cleaning body 18, the rotating rotor does not stop or overload is applied to the motor that drives the rotation of the cleaning body 18, and the fibers are continuously arranged. The surface can be cleaned uniformly. However, since the belt-like body 18a of the cleaning body 18 is formed by bending a long fiber bundle in a meandering manner, it is effective to polish the surface of the surface to be cleaned. In other words, the wiping performance is inferior, that is, the wiping performance is inferior, and the fiber bundle of the loop portion of the free end 19 is frayed by the friction with the surface to be cleaned, so that the fibers are broken and the loop-shaped portion is opened. When inserting the mounting member 18b into the support groove 17a provided on the rotor 17, the fiber bundle is caught in the support groove 17a, shifted, cut, and frayed from there. There was a problem.

  The present invention solves the above-described conventional problems, and provides a rotary rotor, a floor suction tool for a vacuum cleaner, a vacuum cleaner, and an air conditioner that are excellent in assembling and durability and excellent in dust scraping performance. It is for the purpose.

Since the end portion formed by bending the center portion of the blanket is in a loop shape, a space is formed between the base material of the brushed fabric and the rotor, and the brushed fabric is easily bent by the space portion. As a result, a strong compressive force is applied to the raised cloth when cleaning the surface to be cleaned. The rotating rotor does not stop or overload is applied to the motor that drives the rotation of the rotor, and the fibers of the raised cloth are continuously arranged, and further, the fibers of the raised cloth protrude outward. It cleans the surface to be cleaned uniformly, is not easily frayed, and has excellent dust scraping performance.

Embodiments of the present invention will be described below with reference to the drawings. In addition, this invention is not limited by this Example.

  FIG. 1A is a perspective view of a rotary rotor in the first embodiment of the present invention, FIG. 1B is a perspective view of the rotor of the rotary rotor, and FIG. 1C is a perspective view of a cleaning body of the rotary rotor. It is.

  In FIG. 1, the rotary rotor 20 in this embodiment is formed in a rod shape with a metal material such as aluminum or an alloy thereof, and rotates to equipment (not shown) such as a vacuum cleaner floor suction tool or an air conditioner. The rotor 21 is freely attached, and the cleaning body 22 is detachably attached to the rotor 21 and scrapes off dust on a surface to be cleaned (not shown). A pair of support grooves 23 are formed in a straight line in the longitudinal direction of the outer periphery of the rotor 21, and the cross-sectional shape of the support grooves 23 is a substantially ridge shape over the entire length of the rotor 21 as shown in FIG. The opening 21a formed in the outer periphery of 21 is formed so as to be narrower than the inside.

  The cleaning body 22 is a belt-like base material 24a and a brushed cloth 24 made of ultrafine fibers 24b such as polyester and nylon implanted in the base material 24a, and is fixed to both ends in the longitudinal direction of the brushed cloth 24. And a base portion 25 that is detachably mounted in the support groove 23.

  In this embodiment, as shown in the figure, the base portions 25 of the two cleaning bodies 22 are mounted in the two support grooves 23. Specifically, the rotary rotor 20 is assembled by bending each of the two raised cloths 24 at a substantially center with the base material 24a inside, and combining one base portion 25 of each of the two cleaning bodies 22 together. In the same manner, the other base 25 of each of the two cleaning bodies 22 is also put together and mounted in the other support groove 23. Thereby, the cross-sectional shape of the end portion 22a in the radial direction of the cleaning body 22 becomes a loop shape, and a space portion 26 is formed between the base material 24a of the raised cloth 24 and the surface of the rotor 21.

  As described above, according to the present embodiment, the end portion 22a formed by bending the central portion of the raised cloth 24 has a loop shape, and a space is formed between the base material 24a of the raised cloth 24 and the rotor 21. Since the portion 26 is formed and the raised cloth 24 can be easily bent by the space portion 26, even when a strong compressive force is applied to the raised cloth 24 of the cleaning body 22 during cleaning of the surface to be cleaned, the rotary rotor 20. Is not stopped, or an overload is not applied to a motor (not shown) for driving the rotation, the fibers 24b of the raised cloth 24 are continuously arranged, and the fibers 24b of the raised cloth 24 are outward. Therefore, the surface to be cleaned is uniformly cleaned, and it is difficult to fray and the dust scraping performance is improved. In addition, since the raised cloth 24 of the cleaning body 22 has a band shape, the cleaning body 22 does not get caught in the support groove 23 when the rotor is attached to the support groove 23. Easy.

  In addition, since the base 25 of the two adjacent cleaning bodies 22 is attached to one of the support grooves 23, no gap is generated between the two adjacent cleaning bodies 22, and the cleaning effect by the cleaning body 22 is improved. Since the base 25 of the two adjacent cleaning bodies 22 is mounted with one large support groove 23, the number of the support grooves 23 can be reduced, and the strength of the rotor 21 due to the provision of the extra support grooves 23 can be reduced. While preventing the decrease, the assembly man-hours can be reduced.

  In the above-described embodiment, the two cleaning bodies 22 are held by the two support grooves 23. However, as shown in FIG. Only 22 may be supported. Furthermore, as shown in FIG. 2B, the rotor 21 is provided with only one support groove 23, and two base portions 25 fixed to both side ends of one raised cloth 24 are provided in the support groove 23. Together, it may be mounted in the one support groove 23. In any case, the width dimension of the raised cloth 24 is determined so that a predetermined space 26 can be secured between the surface of the rotor 21 and the base material 24a of the raised cloth 24. As described above, according to the configuration shown in FIG. 2, only one brushed cloth 24 is required, so that the rotary rotor 20 can be formed at low cost.

  Furthermore, as shown in FIG. 3, the three cleaning bodies 22 may be supported by the three support grooves 23 provided evenly on the outer periphery of the rotor 21. When the number of the support grooves 23 and the cleaning bodies 22 is increased, the number of assembling steps is increased. By increasing the number of the support grooves 23 and the cleaning bodies 22, the distance between the end portions 22a of the two adjacent cleaning bodies 22 is reduced. Sometimes the impact applied to the surface to be cleaned is reduced, and noise can be reduced.

  With the above configuration, when a strong compressive force is applied to the raised cloth 24 during cleaning of the surface to be cleaned by the rotary rotor 20, the receiving rib 28 is greatly bent as shown in FIG. Since the tip of the receiving rib 28 is held by the holding groove 29, the receiving rib 28 is prevented from returning to the original position, and the bending performance of the raised cloth 24 is improved over a long period of time. Can be maintained.

  FIG. 6A is a perspective view of a rotating rotor in a fourth embodiment of the present invention, FIG. 6B is a perspective view of a rotor of the rotating rotor, and FIG. 6C is a perspective view of a receiving rib of the rotating rotor. . The same parts as those in the third embodiment are designated by the same reference numerals and the description thereof is omitted.

  In the said 3rd Example, although the receiving rib 28 which absorbs the compression force added to the raising cloth 24 was integrally or integrally formed in the base material 24a of the raising cloth 24, in this embodiment, FIG. As shown in (c), a receiving rib 49 that absorbs the compressive force applied to the raised fabric 24 is formed as a separate part from a material having a high elasticity such as silicon rubber, and the longitudinal direction of the rotor 21 is formed at one end.

Therefore, the receiving rib 49 is prevented from returning to its original position. The bending performance of the raised fabric 24 can be maintained over a period of time. Further, since the receiving rib 49 is a separate part from the raised cloth 24, the raising of the raised cloth 24 is simplified, and when the elasticity of the receiving rib 49 deteriorates, only the receiving rib 49 needs to be replaced. Is easy.

  Instead of the receiving rib 49, as shown in FIG. 6D, the brush material 50a made of a large number of fibers and hairs and the lower end of the brush material 50a are fixed, and the holding groove 29 of the rotor 21 is fixed. You may utilize the brush body 50 which consists of the base 50b with which it mounts | wears. When the base 50b is attached to the holding groove 29, the brush body 50 receives the base material 24a of the raised cloth 24 at the tip of the brush material 50a.

  According to this configuration, when the raised fabric 24 receives a compressive force from the outside, the base material 24a of the raised fabric 24 is received at the tip of the brush material 50a made of a plurality of fibers, hairs, etc., and the impact is softer. In addition, it can be reliably absorbed, and is suitable for cleaning surfaces to be cleaned that have a relatively rough surface and are not very strong in strength, such as an air filter (not shown) mounted on an air conditioner. is there.

  FIG. 10 is a longitudinal sectional view of an air conditioner according to a sixth embodiment of the present invention, and FIG. 11 is a perspective view schematically showing an internal configuration of the air conditioner. In addition, about the same part as the said Example, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  10 and 11, an air conditioner body 60 is disposed between a heat exchanger 61, a suction port 62 for taking in indoor air, and between the heat exchanger 61 and the suction port 62. An air filter 63 that captures dust contained in the inflowing air, a rotary rotor 20 that is disposed on the upstream side of the air filter 63 and that removes dust captured by the air filter 63, and the rotary rotor 20. Rotation drive means (not shown) for rotationally driving, vertical movement means (not shown) for moving the rotary rotor 20 in the vertical direction along the upstream surface of the air filter 63, and the suction port 62 There is provided a fan 67 that sucks indoor air, blows out the heat-exchanged air into the room through an air filter 63 and a heat exchanger 61 and from an outlet 66. The rotary rotor 20 is the same as that described in the first to third embodiments.

  In the present embodiment, the air filter 63 is divided into two parts on the left and right sides, and is detachable from the air conditioner body 60 for easy cleaning. The rotary rotor 20 is provided to face each air filter 63.

  In the present embodiment, the effective cleaning width L1 of the rotary rotor 20 (the overall width dimension of the cleaning body 22) is set to at least 300 mm in accordance with the width dimension of the air filter 63 for a general air conditioner.

  The operation and action of the air conditioner configured as described above are as follows.

  For example, when the air conditioner body 60 is in a cooling operation, indoor air flows from the suction port 62 by the operation of the blower fan 67, passes through the air filter 63, reaches the heat exchanger 61, is cooled there, and cool air blows out. The air is blown out from the mouth 66 into the room. Dust contained in indoor air sucked from the suction port 62 is captured by the air filter 63 and gradually accumulates on the surface of the air filter 63. If dust accumulates on the surface of the air filter 63, the air pressure loss of air increases and the heat exchange efficiency in the heat exchanger 61 decreases, so the air filter is periodically or as necessary. An operation for removing the dust accumulated on 63 is required.

  Therefore, in this embodiment, when the dust removal operation is started, as shown in FIG. 10, the rotary rotor 20 located at the lower end of the air filter 63 is moved in the direction indicated by the arrow (clockwise) by the rotation drive means (not shown). While moving in the direction), the upper and lower moving means (not shown) moves upward along the surface of the air filter 63. During this time, the dust adhering and accumulating on the upstream surface of the air filter 63 is scraped off at the loop-shaped end 22 a of the cleaning body 22 of the rotary rotor 20. The dust scraped off is sucked by a dust suction means (not shown) and discharged to the outdoors.

  When the rotary rotor 20 reaches the upper end of the air filter 63 by the vertical movement means, it automatically descends and stops at the lower end of the air filter 63 for the next dust removal operation. Further, the rotation direction of the rotary rotor 20 may be a direction opposite to the arrow direction (counterclockwise direction), and the rotation direction may be appropriately determined in consideration of cleaning performance and the like.

  As described above, according to the present embodiment, since the rotary rotor 20 excellent in cleaning performance, durability, handleability, and assemblability is used for cleaning the air filter 63, the cleaning performance and durability are improved. An excellent air conditioner can be provided at low cost.

  In the above-described embodiment, the rotary rotor 20 is provided for each of the two air filters 63. However, the two air filters 63 may be simultaneously cleaned by one long rotary rotor 20. good.

  As described above, the rotary rotor according to the present invention is excellent in cleaning performance, durability, handleability, and assemblability, and is not limited to a vacuum cleaner or an air conditioner, but an air filter such as an air cleaner or a ventilator. It can also be widely used in various devices having the above.
