Description
The present invention relates to an electric vacuum cleaner, and more particularly, to an electric vacuum cleaner having a novel nozzle opening body.
In a nozzle opening body for a general vacuum cleaner, an axle is fixed in a lower case of the nozzle opening body, as disclosed in, for example, japanese patent application laid-open No. 11-253370.
However, in the technique disclosed in japanese patent laid-open No. 11-253370, when the nozzle opening body is used for a long time, there is a problem that the wheels are worn to damage the floor or noise is generated.
An object of the present invention is to solve the above problems by a movable structure and to provide a vacuum cleaner including a nozzle opening body which can reduce the number of parts, and can fix a wheel shaft or a brush base body and can be replaced with a new wheel or brush body when the wheel and brush body are worn.
The present invention may be summarized as a vacuum cleaner including: a vacuum cleaner main body having an electric fan and preferably a dust collecting portion; a nozzle opening body formed by placing an upper housing on a lower housing having an opening portion on a side of a surface to be cleaned; a wheel having an axle, the wheel being disposed at the nozzle opening main body portion on the side to be cleaned, wherein the axle is detachably fixed to the lower housing by a bushing, and particularly, the axle is fixed to the lower container while the lower housing and the upper housing are fixed to each other. In addition, the vacuum cleaner according to the present invention includes a front wheel and a rear wheel in the forward direction, and a rear wheel shaft of the rear wheel is fixed by the above-mentioned bush.
Furthermore, the invention features a vacuum cleaner including: a vacuum cleaner body having an electric fan and preferably a dust collecting portion; a nozzle opening body formed by placing an upper housing on a lower housing having an opening portion on a side of a surface to be cleaned; a rotary cylindrical brush body having a shaft, the rotary cylindrical brush body being disposed at the suction nozzle opening main body on the side of the surface to be cleaned, wherein the brush is attached to the base body of the rotary cylindrical brush body on the side of the surface to be cleaned, and the shaft of the rotary cylindrical brush body is detachably fixed to the lower housing through a boss. In addition, in the case where the rear wheel is replaced with the rotary cylindrical brush body as described above, the sleeve is fixed to the lower housing to simultaneously fix the lower housing and the upper housing to each other. The invention features a vacuum cleaner including a front wheel and a rotating cylindrical brush body.
The invention features a vacuum cleaner including: a flexible hose connected to the vacuum cleaner body; a hose clamp handle portion connected to the flexible suction tube; a first extension tube connected to a handle portion of the hose clamp; a second extension pipe slidably connected to the first extension pipe; a nozzle opening joint connected to the second extension pipe; a housing connected to the nozzle opening joint and the nozzle opening body; wherein the housing is connected to a nozzle opening body such that it can be rotated preferably over forty degrees, in particular forty-five to ninety degrees, in the vertical direction of the surface to be cleaned, and the nozzle opening joint is connected to said housing such that it can be rotated preferably over three hundred sixty degrees, at least one hundred eighty degrees, in the horizontal direction of the housing.
In addition, when one end of the wheel shaft, which is not fixed by the boss, is fixed from above and below by the lower case and the upper case, the corners of the lower case become sharp on the side of the surface to be cleaned. Therefore, it is preferable to insert a metal sheet into the corner portion of the lower case in a direction parallel to the surface to be cleaned to make the corner as round as possible, thereby preventing the generation of flaws on the floor.
Only by removing the sleeve, the worn wheel or the worn rotary cylindrical brush body can be easily replaced with a new wheel or a new rotary cylindrical brush body. Therefore, it is possible to prevent the surface to be cleaned from being flawed and prevent the generation of "checkered" noise. In addition, since the boss is fixed together with the lower case and the upper case, an increase in the number of parts can be suppressed. Furthermore, the metal piece is inserted into the corner portion of the lower housing at the end of the wheel axle not fixed by the bushing in a direction parallel to the surface to be cleaned, creating a large rounded surface within the lower housing. Thus, the axle can be secured by only one bushing without leaving imperfections on the surface to be cleaned.

Fig. 5 is a perspective view showing the bottom surface of the nozzle opening body 905 when the brush cover 122 and the rotating cylindrical cleaning body 117 are removed from the bottom surface of the nozzle opening body 905.
Referring to fig. 1 to 5, a nozzle opening main body 100 as a housing of the nozzle opening body 905 is divided into upper and lower parts at a nearly middle horizontal position of the nozzle opening main body, and the nozzle opening main body 100 is composed of a lower housing 101 forming a housing and having a suction port 103; and an upper case 102 disposed on the lower case 101.
An elastic shock-absorbing buffer 104 is installed at a peripheral position of the front surface and the side surface where the lower case 101 and the upper case 102 are coupled to each other to maintain airtightness and prevent damage to furniture.
The nozzle opening body 100 includes a housing 108 at its rear end to form a vertically rotatable first joint having a rotating shaft rotatably disposed on the support portion 105 and an opening portion 107, and is connected to a nozzle opening joint 109 forming a second joint horizontally rotatable with respect to the nozzle opening body. In the present embodiment, a nozzle opening joint 109 forming a second joint is rotatably connected to a housing 108 forming a first joint that is vertically rotatable with respect to the nozzle opening body 100. However, the first joint may be configured to be rotatable in a circumferential direction with respect to the rear surface of the nozzle opening body 100, and the second joint may be rotatably connected to the first joint in a vertical direction with respect to the nozzle opening body 100. By these joints, the orientation of the nozzle opening body 100 can be arbitrarily changed.
The lower case 101 and the upper case 102 are fixed to each other by screws 110. A rotational shaft 106 of a housing is provided between the lower case 101 and the upper case 102 and is rotatable in the vertical direction. The configuration of the present embodiment allows the housing 108 to be rotated vertically to ninety degrees. In addition, a louver member 111 is interposed between the housing 108 and the lower housing 101. The louver members 111 are positioned to effect closing of the gap between the housing 108 and the lower housing 101 when the housing 108 is rotated upwardly to approximately ninety degrees.
Wheels are disposed at the bottom of the lower housing 101 to facilitate moving the entire suction nozzle opening body 905 forward and backward, and to maintain a fixed gap between the bottom surface of the suction nozzle opening body 905 and the surface to be cleaned and to protect the surface to be cleaned. These wheels are composed of a pair of front wheels 112 disposed on both sides of the lower housing 101 and a rear wheel 113 for receiving a pressure to the surface to be cleaned when the vacuum cleaner is used, the pair of front wheels 112 being rotatably supported by a wheel shaft 112a, whereby the nozzle opening main body 100 can be moved forward and backward; the rear wheel 113 is also rotatably supported by the wheel shaft 113a, whereby the nozzle opening main body 100 can be moved forward and backward. A piece of convex fabric is attached to the resin base surface of the rear wheel 113, and the rear wheel 113 is gradually reduced in diameter from the middle portion toward both ends, whereby the nozzle opening main body 100 can be freely oriented in a plurality of directions.
One end of the axle 113a of the rear wheel 113 is covered with a bushing, the bushing 114 is fixed by a bearing portion through the bushing 114 with a screw 115, and the screw 115 is also used to fix the lower case 101 and the upper case 102. On the other hand, the other end of the axle 113a of the rear wheel 113 has a flat portion, so the axle 113a itself does not rotate, and the axle is inserted into a bearing hole of a lower housing 101 having a similar structure thereto, the lower housing 101 being detachably fixed to the nozzle opening main body 100 by fixing the lower housing 101 and the upper housing 102 together. The rear wheel 113 and the wheel shaft 113a are each formed separately. The bushing 114 has a bearing portion for fixing the hub 113a and a screw hole portion, and the screw hole portion may be hemispherical or spherical. Alternatively, each end of the axle 113a may be similarly secured by a bushing 114.
The front wheels 112 are disposed on both sides of the lower case 101, each of which is composed of a metal-made wheel shaft 112a and a resin-made wheel, and the wheel shaft 112a is restrained and fixed to the lower case 101 made of resin.
In addition, a pressure control sheet 116 for maintaining the suction pressure in the suction port 103 is disposed on the front side of the lower casing 101.
A rotary cylindrical cleaning member 117 for removing dust, dry-wiping the surface to be cleaned, etc. is disposed in the nozzle opening body. The rotating cylinder cleaning member 117 is formed by forming grooves on the surface of a rotating cylinder made of metal such as aluminum or resin, and fitting a fur brush 118 and an elastic blade 119 made of vinyl chloride, nylon, rubber or the like on the grooves. A brush 119a is provided at the radial tip end portion of the elastic blade 119, and the brush 119a is fixed to the tip end portion of the elastic blade 119 by sewing the brush 119a and a portion near the tip end portion of the elastic blade 119 with a thread or the like. In the present embodiment, four spiral grooves are formed in the circumferential direction of the rotating cylinder at a phase of ninety degrees from each other, and the brushes 118 and the elastic blades 119 are symmetrically fitted to the grooves, whereby the brushes are opposed to each other and the elastic blades are opposed to each other. Turbine blades 125a, 125b, which are made of an elastic material such as vinyl chloride, nylon, rubber, like the elastic blade 119, are disposed on both sides of the brush 118. There, the number of spiral grooves is not limited to four, but may be arbitrarily selected from two to eight. In addition, the twist angle of the grooves can be arbitrarily selected in the range of ninety to three hundred and sixty degrees. Also, the grooves may be V-shaped from both sides to the middle portion of the rotating cylinder.
A brush cover 122 is disposed at the other end of the lower case 101, and a bearing portion 123 for supporting the bearing 120b at the other end of the rotary cylinder cleaning member 117 is formed in the brush cover 122. The width of the bearing support portion 123 is also greater than the width of the bearing support portion 121. As shown in fig. 3, a hook 124 is provided in the brush cover 122, and the brush cover 122 is constructed such that the brush cover 122 can be removed from the lower housing 101 by rotating the hook 124.
In the present embodiment, the brush cover 122 is detachably attached to the lower case 101, and in addition, a bearing support portion 123 having a width larger than that of the bearing support portion 121 formed in the lower case 101 is formed in the brush cover 122. The rotating cylindrical cleaning member 117 can be easily accessed and removed from the lower housing 101. A recess 124a is formed on the surface of the hook 124, and a flat blade screw driver or a coin can be inserted into the recess 124a to rotate the hook 124. Referring to fig. 3, when the groove 124a of the hook 124 is in a position shown by a dotted line, the brush cover 122 is fixed to the nozzle opening body 905 to support the bearing 120b of the rotary cylinder cleaning member 117, and the rotary cylinder cleaning member 117 is supported in the nozzle opening body 905.
When the groove 124a of the hook 124 rotates from the position shown by the dotted line to the position shown by the solid line, the fixed state of the brush cover 122 is released and the brush cover 122 can be removed from the nozzle opening body 905. Thereby, as shown in fig. 4 and 5, the bearing 120b of the rotary cylinder clearing member 117 is released from the supported state, and the corresponding rotary cylinder clearing member 117 can be easily removed from the nozzle opening body 905. Thereby easily removing objects such as hair, waste thread, etc. wound around the rotary cylindrical removing member.
Referring to fig. 1 and 2, front suction ports 126a and 126b of a first suction port, which is separated from the suction port 103, are formed at the front of the lower housing. Rear suction ports 127a and 127b of the second suction port are also formed in the rear portion of the lower case, and the second suction port is also separated from the suction port 103. The resilient blades 119 and turbine blades 125a, 125b disposed on the rotating cylindrical cleaning member 117 are driven by the airflow through the front and rear suction ports 126a, 126b, 127a, 127 b. The width of the brushes 118 in the direction of the rotation axis of the respective turbine blades 125a, 125b provided at both ends of the brush 118 is larger than the width of the respective front suction ports 126a, 126b and the respective rear suction ports 127a, 127 b. By doing so, each of the turbine blades 125a, 125b can efficiently receive the air flow passing through the front suction ports 126a, 126b and the rear suction ports 127a, 127b to improve the turning moment of the rotating cylindrical scavenging member 117.
The operation of the present embodiment will be described below with reference to fig. 6 to 8.
Fig. 6 is an enlarged view showing a main body portion of the bottom surface of the nozzle opening main body 905; fig. 7 is a view showing a fitting state of the lower housing 101 and the upper housing 102 of the nozzle opening body 905 and a relationship between the nozzle opening body and a surface to be cleaned; fig. 8 is a view showing a relationship between a twisting operation of the hose clamp handle portion 903 and an orientation of the nozzle opening body 905.
As described in the above embodiment, the nozzle opening body 905 according to the present invention is connected to the housing 108 to form a first joint that is vertically rotatable to approximately ninety degrees around the nozzle opening main body 100, and is also connected to the nozzle opening joint 109 to form a second joint that is horizontally rotatable around the nozzle opening main body 100, the nozzle opening joint 109 being connected to the housing 108. Although the nozzle opening body 109 can rotate three hundred sixty degrees relative to the housing 108, only one hundred eighty degrees of rotation is sufficient. As shown in fig. 8(a), when the hose clip handle portion 905 is twisted counterclockwise 801 as viewed from the user direction, the mouthpiece opening body 905 rotates counterclockwise by approximately ninety degrees. Similarly, as shown in fig. 8(b), when the hose clip handle portion 905 is twisted clockwise 802, as viewed from the user's direction, the nozzle opening body 905 rotates clockwise approximately ninety degrees. In this condition, the nozzle opening body 905 can operate in the longitudinal direction 912, and accordingly, cleaning work can be performed by inserting the nozzle opening body 905 into a narrow gap.
When the nozzle opening body 905 operates in the longitudinal direction as described above, the movement direction of the nozzle opening body 905 is different from the rotation direction of the wheels at the bottom thereof. When the nozzle opening body 905 operates in the longitudinal direction as described above, wheels wear or the operating force of the nozzle opening body increases. Therefore, in order to reduce wear of the wheels and operating force of the nozzle opening body, the wheels of the nozzle opening body are covered with a brush or the like in an attempt to reduce frictional resistance.
However, even if the frictional resistance of the wheels is reduced, when the nozzle opening body is used for a long period of time, as shown in fig. 6(a), a worn portion 601 is generated on the wheels (e.g., the rear wheels 113) due to a difference between the rotation direction of the wheels and the moving direction of the nozzle opening body. If the nozzle opening body is used in such a situation, the surface to be cleaned may be flawed and may produce a "grizzly" noise.
In the present embodiment, since the rear wheel 113 is fixed by the bushing, the worn rear wheel can be easily replaced with a new one.
Referring to fig. 6(a), one end of the axle 113a of the rear wheel 113 is covered with a bushing 114. The boss 114 is fixed to the lower case 101 by a screw 115. In that case, when a worn portion 601 is generated on the rear wheel 113, as shown in fig. 6(b), the screw 115 is removed to detach the boss 114 from the lower housing 101 of the nozzle opening body 905. Then, the axle 113a of the rear wheel 113 is detached from the wheel bearing 602 formed in the lower housing 101 to detach the rear wheel 113.
When a new rear wheel 113 is mounted, the wheel shaft 113b side of the rear wheel 113 is inserted into the lower case, and the wheel shaft 113a side is inserted into the wheel bearing 602. After the wheel shaft 113a is inserted into the wheel bearing 602, the shaft sleeve 114 is covered to the wheel shaft 113a, and then the shaft sleeve 114 is fixed to the lower case 101 with the screw 115.
In the present embodiment described above, the detachable structure of the rear wheel 113 has been described. The detachable wheels are not limited to the rear wheels 113, but may be wheels facing below the nozzle opening body, for example, the front wheels 112 may be constructed similarly to the above-described structure.
According to the present embodiment, since the rear wheel 113 is made in an easily detachable structure, the rear wheel can be easily replaced even if the worn portion 601 is generated at the rear wheel 113. This prevents flaws from being left on the surface to be cleaned and prevents "gridlike" noises that may occur.
In the present embodiment as described above, the detachable structure of the rear wheel 113 has been described. The front wheel 112 may also be removable. In addition, the detachable parts are not limited to the wheels, and a rear brush body 128 composed of a base body 128a, a brush 128b and a base body shaft 128c is directed downward of the nozzle opening body, and the rear brush body 128 may be constructed similarly to the above-described structure.
Fig. 7 is a view showing the relationship between the main portion of the hub fixing portion and the surface to be cleaned. As shown in fig. 7(a), since the end of the hub 113a not fixed by the bushing 114 is fixed by being placed between the lower housing 101 and the upper housing 102, and the contact surface 701 between the lower housing 101 and the upper housing 102 is made close to the surface to be cleaned. Accordingly, it is difficult to round the corner of the lower housing 101 opposite to the surface to be cleaned. Thus, as shown in fig. 7(b), the hub 113a is inserted into the lower housing 101 in a direction parallel to the surface to be cleaned, and the bearing hole 701 is formed only on the lower housing 101. Reference numeral 703 denotes a narrow pressed portion. By adopting such a structure, the hub 113a is fixed only by the boss 114, and a round surface can be formed in the lower case 101.
As described above, since the worn wheel or the worn brush can be easily replaced with a new one just by detaching the sleeve, it is possible to prevent flaws from being left on the surface to be cleaned and to prevent the generation of "rattling" noise. In addition, since the sleeve is fixed together with the upper and lower cases, an increase in the number of parts can be suppressed. In addition, the metal member is inserted into the corner of the lower housing in a direction parallel to the surface to be cleaned on the side where the wheel axle is not fixed by the boss, and a large rounded surface may be formed in the lower housing. Therefore, the wheel axle can be fixed by only one shaft sleeve without leaving flaws on the surface to be cleaned.
