Definitions

  • the present invention relates to vacuum cleaners, and more particularly, to a main body of a vacuum cleaner in which convenience in use is improved.
  • a vacuum cleaner is an electric product capable of collecting dusts or foreign particles using a dust bag installed in an inside of a main body of the vacuum cleaner, by sucking dusts or foreign particles on a polluted floor or a corner using strong suction force from a rotating motor.
  • Vacuum cleaners are generally classified into canister vacuum cleaners and upright vacuum cleaners.
  • the canister vacuum cleaner includes a vacuum cleaner main body separately formed, and a nozzle unit and a knob unit which are integrally formed. If a user grips a knob unit to push and pull it, the vacuum cleaner main body remains fixed and just the nozzle unit and the knob unit are moved.
  • the vacuum cleaner main body includes a suction fan for sucking an outer air, a motor for providing rotational force with which the suction fan is rotated, and a dust collecting assembly for filtering foreign particles included in the sucked air.
  • the general canister vacuum cleaner includes, as separate parts, a lower cover on which the motor, the suction fan, and the dust collecting assembly are seated, and an upper cover for covering the lower cover.
  • the upper cover has a dust bag as the dust collecting assembly in its inside so that foreign particles included in a sucked air may be filtered while the air is passing through the dust bag, whereby a cleaning work is performed.
  • the dust bag is received within a dust collecting room, space or cavity formed by subsiding in a predetermined position of the lower cover.
  • the lower cover is deformed by an excessive negative pressure applied to the dust collecting space, thus an appearance of the vacuum cleaner is not very good. Furthermore, in case the lower cover is deformed, fitting and contact states between parts are deteriorated and an outer air is sucked, so that malfunction may be generated. Therefore, a predetermined reinforcing structure capable of reinforcing the dust collecting room or space is highly required.
  • the present invention is directed to a main body structure of a vacuum cleaner, that addresses one or more problems due to limitations and disadvantages of the related art.
  • a main body structure of a vacuum cleaner includes: a motor chamber for receiving at least a motor to generate a suction force; a lower case in which the motor chamber is received and part of an upper portion of which is open so that an air discharged from the motor chamber may be discharged upward; an intermediate unit positioned on an upper side of the lower case and in which at least a dust collecting unit is formed; a dust collecting structure placed in an inside of the dust collecting unit, for filtering foreign particles included in the air flowed into the dust collecting unit; and a dust collecting unit cover formed on an upper portion of the intermediate unit so that an inner space of the dust collecting unit may be selectively open.
  • deformation of a vacuum cleaner cover which may be generated during operation of the vacuum cleaner can be prevented and the appearance of the vacuum cleaner can be improved.
  • handling of the vacuum cleaner can be performed in a more easy and convenient manner.
  • Fig. 1 is a perspective view illustrating a construction of a vacuum cleaner according to the present invention.
  • the vacuum cleaner includes a main body 100 for generating a suction force, a connection hose 200 connected so as to communicate with an inside of the main body 100 and made of flexible material, an extension tube 300 connected with the connection hose 200 in a length-adjustable manner, and a suction nozzle 400 joined to an end of the extension tube 300, for sucking foreign particles on a floor.
  • a pair of wheels 110 are installed on a rear side of the main body 100 so as to possibly rotate while contacting the floor, which enables a user to move the main body 100 to a desired direction.
  • a user grips a hose knob 210 formed in the connection hose 200 to move to a desired direction.
  • a user grips a main body knob 120 protruded in a predetermined height from an upper portion of the main body 100 to lift up and move the vacuum cleaner.
  • Fig. 2 is an exploded, perspective view of a vacuum cleaner main body according to the present invention
  • Fig. 3 is a cross-sectional view taken along line I-I' of Fig. 1, in which a longitudinal, cross-sectional view of the vacuum cleaner main body is illustrated.
  • the main body 100 has, in its lower portion: a motor chamber in an inside of which a motor for generating a suction force is received; a lower case 140 for receiving the motor chamber in its inside and forming a lower appearance of the main body 100; an intermediate unit 150 formed on an upper side of the lower case 140 and in which a dust collecting unit 152 is formed; and a dust collecting unit cover 170 for making the dust collecting unit 152 opened/closed on an upper side of the intermediate unit 150.
  • a discharging unit 134 configured in an about net-shape to have a predetermined air permeability so that an air flowed into the motor chamber 130 may be discharged to the outside of the main body 100, is formed on an upper portion of the motor chamber 130.
  • the discharging unit 134 is open in an upward direction from the main body 100 so that an air flowed into an inside of the motor chamber 130 may be discharged to an upward direction of the main body 100.
  • an inlet 132 for allowing an air to flow into an inside of the motor chamber 130 is protruded on a front portion of the motor chamber 130. The inlet 132 gets close to a separation wall 142 which will be described below, so that the air flowing into the inside of the motor chamber 130 may not leak out.
  • the separation wall 142 protruded vertically upward in a predetermined thickness is provided to an approximately central portion of the lower case 140.
  • the separation wall 142 partitions an inner space of the lower case 140 into left and right areas, so that the motor chamber 130 may be possibly mounted on the right side of the separation wall 142.
  • the intermediate unit 150 which shields a front portion of the motor chamber 130 and in which the discharging unit 134 is inserted is provided to an upper side of the lower case 140.
  • the dust collecting unit 152 formed by subsiding downward in a predetermined depth so that the dust bag 151 for filtering dusts can be stored is provided to a front portion of the intermediate unit 150.
  • a bottom side of the dust collecting unit 152 has a shape that corresponds to a front bottom side of the lower case 140 so that a vibration noise generated due to collisions between the intermediate unit 150 and the lower case 140 during operation of the vacuum cleaner may be reduced.
  • a predetermined buffering member may be further provided to a gap where the intermediate unit 150 and the lower case 140 contact each other so as to absorb the vibration in a reliable manner.
  • other type dust collecting structure such as a cyclone dust collecting unit may be mounted instead of the dust bag 151.
  • a discharging unit through hole 154 punched in a size that corresponds to the size of the discharging unit 134 is provided to a rear portion of the dust collecting unit 152.
  • the discharging unit through hole 154 is a portion into which the discharging unit 134 is inserted. After inserted, the discharging unit 134 is exposed to the outside of the main body 100. As described above, an air can be discharged through the discharging unit 134.
  • a partition plate 156 constituting one side of the dust collecting unit 152 is formed on an approximately central portion of the intermediate unit 150.
  • the partition plate 156 is formed in a plate shape including a plurality of air permeable holes so that an air purified by the dust bag 151 of the dust collecting unit 152 may flow into the motor chamber 130 through the air permeable holes.
  • the dust bag 151 operates in such a way that an outer air flows into an inside of the dust bag 151 and foreign particles included in the flowed outer air is filtered by an external film of the dust bag 151 and then the air is discharged to the outside.
  • the dust collecting unit 152 covers and shields a front portion of the lower case 140, so that the dust collecting unit 152 is completed, and the discharging unit through hole 154 receives the discharging unit 134, whereby the discharging unit 134 is exposed to the outside of the main body 100.
  • a dust bag fixing unit 160 is provided to an upper portion of the intermediate unit 150.
  • the dust bag fixing unit 160 which has a shape that corresponds to an opening of the dust collecting unit 150, shields an upper side of the dust collecting unit 152 with its one side fastened to the dust bag 151 for filtering dusts, thereby preventing dusts from leaking out to the outside of the dust collecting unit 152.
  • the dust collecting unit cover 170 is provided to an upper portion of the dust bag fixing unit 160.
  • the dust collecting unit cover 170 allows the upper side of the dust collecting unit 152 to be selectively opened so that the dust collecting unit 152 may be easily opened when the dust bag 151 is replaced.
  • hinges 172 acting as a rotational shaft of the dust collecting cover 170 are protruded on both ends on an upper portion of the dust collecting cover 170. The hinges 172 are inserted and fixed to both ends of the knob 120 of the main body, thereby allowing the dust collecting unit cover 170 to rotate around the hinges 172.
  • connection hole 174 punched in a shape that corresponds to a shape of an end of the extension tube 300 is provided to an upper surface of the dust collecting unit cover 170.
  • the connection hole 174 is connected with the extension tube 300, whereby an air including foreign particles and sucked from the suction nozzle 400 goes through the extension tube 300 and the connection hose 200 and finally flows into the dust bag 151 of the dust collecting unit 152.
  • a suction force is generated by a motor 131 mounted in an inside of the main body 100.
  • the suction force generated by the motor 131 is delivered to the suction nozzle 400 to inhale foreign particles included in an air on a floor.
  • the air including the foreign particles flowed into the suction nozzle 400 goes through the extension tube 300, the connection hose 200, and the connection hole 174 and finally flows into an inside of the dust bag 151.
  • the foreign particles flowed into the inside of the dust bag 151 are purified by the dust bag 151 and the purified air goes through an outside of the dust bag 151, i.e., the dust collecting unit 152 and the partition plate 156 and flows into the motor chamber 130 provided to the rear portion of the cleaner main body 100. After that, the air flowed into the motor chamber 130 goes through an inside of the motor 131 and is discharged to an outside of the main body 100 through the discharging unit 134 formed in a punching manner on an upper portion of the motor chamber 130, whereby a cleaning work is performed.
  • the dust collecting unit cover 170 is rotated upward around the hinges 172 so that the dust collecting unit 152 is open. After that, the dust bag fixing unit 160 is detached from the main body 100, so that the dust bag 151 fixedly mounted on a back side of the dust bag fixing unit 160 can be replaced.
  • the vacuum cleaner when the vacuum cleaner operates, a strong negative pressure is generated in an inside of the dust collecting unit 152 as described above. Injected parts of the intermediate unit 150 constituting the dust collecting unit 152 may be deformed by such a negative pressure. For prevention of such deformation, the intermediate unit 150 is formed in a double structure. Construction of the intermediate unit 150 will be described in detail in the following.
  • Fig. 4 is a cross-sectional view taken along line II-II' of Fig. 2.
  • an intermediate unit's outline constituting the dust collecting unit 152 includes an inner case 155 to which a negative pressure from the inside of the dust collecting unit 152 is directly applied, and a skirt 153 extended downward from an upper end of the inner case 155.
  • the skirt 153 is a part touched to an outer periphery of the lower case 140 and thus observed by a user's natural eye.
  • the inner case 155 is a part to which a negative pressure generated from the motor chamber 130 is directly applied.
  • the inner case 155 further includes a separate structure so that the inner case 155 may not be deformed even by the above-described negative pressure.
  • the inner case 155 further includes a vertical rib 158 formed long in an up/down direction of the dust collecting unit 152 and a horizontal rib 157 formed in a left/right direction of the dust collecting unit 152.
  • the vertical rib 158 is a part formed by being bent in a relatively wide area of the intermediate unit 150 when injection process is performed and forms the same thickness as the whole thickness of the intermediate unit 150.
  • the horizontal rib 157 is a part formed thick on a relatively narrow area of the intermediate unit 150 unlike the thickness of the intermediate unit 150 itself. Thus, even in case the dust bag 151 is touched to the horizontal rib 157 when the dust bag 151 is detached/attached, there is low possibility that the dust bag 151 is torn.
  • the vertical rib 158 is formed large as described above, the case of the intermediate unit 150 can be maintained without deformation against the strong negative pressure.
  • the vertical rib 158 formed large is bent in the same thickness as the intermediate unit 150 itself, thus the injection process can be performed conveniently and shrinkage generated upon cooling after the injection process is performed can be reduced.
  • the part observed by a user's natural eye is the skirt 153 and the inner case 155 is a part not observed by a user's natural eye.
  • a user comes to see just the skirt 153 whose appearance is clean and elegant, so that a user's purchasing desire is promoted.
  • the inner case 155 does not highly require great elaborateness in its injection process, thus convenience in the manufacturing process is enhanced.
  • deformations of the parts which may be generated during operation of the vacuum cleaner, can be prevented and the appearance of the vacuum cleaner becomes elegant. Further, convenience in the manufacturing process of the vacuum cleaner is enhanced.
  • the vacuum cleaner main body in which the appearance of the vacuum cleaner can be elegantly realized is provided.
  • the discharging unit is provided to the upper portion of the vacuum cleaner, flying of goods or scattering of dusts in the neighborhood of the vacuum cleaner is prevented.
