Description

  The present invention relates to a vacuum cleaner provided with a dust collection container having a lid for discarding collected dust.

  In recent years, vacuum cleaners equipped with a cyclone type dust collecting device that separates relatively large dust by centrifugal force by swirling the sucked air in the dust collecting container and deposits it on the bottom of the dust collecting container have become widespread. Patent Documents 1 and 2 disclose related arts related thereto.

  The vacuum cleaners described in Patent Documents 1 and 2 include a main body portion that incorporates an electric blower. An extension pipe is connected to the suction port facing the surface to be cleaned, and a connection port provided in the main body and the extension pipe are connected by a flexible connection hose. A cyclone type dust collector is disposed in the main body in front of the electric blower.

  The dust collector includes a detachable dust collecting container formed in a cylindrical shape having a circular cross section having an opening surface on the upper surface and the bottom surface. An inflow port that communicates with the connection port and allows the air from the connection port to flow in the circumferential tangential direction is provided on the upper peripheral surface of the dust collecting container. In the dust collecting container, a swirling airflow is formed by the air flowing from the inlet.

  In the dust collection container, an inner cylinder having an air flow outlet on its peripheral surface is coaxially arranged. A partition member is attached to the inner cylinder to form an air flow path between the inner surface of the dust collecting container and partition the dust collecting container up and down. A circular filter in plan view covering the opening surface of the upper surface of the dust collecting container is disposed above the inner cylinder. The downstream side of the airflow of the filter communicates with the electric blower.

  In the vacuum cleaner having the above-described configuration, dust on the surface to be cleaned is sucked together with air from the suction port body by driving the electric blower. The air sucked from the suction port body flows into the dust collecting container of the dust collector from the inlet through the extension pipe and the connecting hose. The air that has flowed into the dust collecting container swirls within the dust collecting container, and large dust is separated by centrifugal force and accumulated on the bottom of the dust collecting container.

  The airflow from which large dust has been removed flows through the inner cylinder through the outlet, and fine dust is collected by the filter. The airflow from which fine dust has been removed flows out of the dust collector. The air that flows out from the dust collector passes through the electric blower and is exhausted to the outside. Thereby, the surface to be cleaned can be cleaned.

  A lid is provided at the position of the opening on the bottom surface of the dust collecting container. The lid is provided so as to be openable and closable with respect to the opening on the bottom surface of the dust collecting container. The dust collected in the dust collecting container can be discarded by removing the dust collecting container from the dust collecting device and opening the lid. The lid is opened downward by the operation of the lock release button, and the dust in the dust collecting container falls along with the opening.

  Since the lid of the electric vacuum cleaner having the above configuration opens downward with respect to the dust collecting container, there is a high possibility that a large impact is applied to the hinge portion connecting the dust collecting container and the lid by the action of gravity. Thereby, it is necessary to form a hinge part firmly. Therefore, the conventional vacuum cleaner forms a relatively large hinge portion that can withstand an impact, and the hinge portion is fixed to the outer peripheral surface of the dust collecting container with a screw as a fastening member. As a result, the hinge part itself becomes relatively large, and the boss part for fixing with a screw also becomes large, which causes a problem that the material for forming the hinge part increases. And there existed a possibility that a dust collector might also be enlarged with the enlargement of a hinge part.

  Furthermore, since the conventional vacuum cleaner is configured independently with respect to the other members constituting the lock device, the lock release button of the lid portion increases the number of parts, and the material related to the formation of the lock device is increased. There was an increasing problem. And there existed a possibility that a dust collector might also be enlarged with the enlargement of the locking device by the increase in a number of parts.

  This invention is made in view of said point, and provides the vacuum cleaner which can aim at suppression of the usage-amount of the material which concerns on formation of a dust collector, and suppression of the enlargement of a dust collector. For the purpose.

  In order to solve the above-mentioned problems, the present invention is formed in a cylindrical shape having a circular cross section having an opening surface on the bottom surface, and is detachable with respect to a main body having a built-in electric blower, and the dust collecting container A hinge provided on an outer peripheral surface of the dust collecting container for connecting the dust collecting container and the lid, in a vacuum cleaner provided with a lid part that is openable and closable with respect to the opening surface A shaft portion serving as a rotation center of the lid portion that is provided on the hinge portion and opens and closes, and a holding member attached to the outer peripheral surface of the dust collecting container to hold the shaft portion, The holding member is attached to the outer peripheral surface of the dust collecting container using a fastening member, a claw portion provided on the holding member and the dust collecting container, and a locking portion including a locking hole thereof. It is characterized by.

  According to this configuration, since the vacuum cleaner is attached to the dust collecting container using the locking portion, the holding member for providing the lid portion that can be opened and closed with respect to the dust collecting container is used. Is reduced. Therefore, the hinge portion itself becomes relatively small, and the boss portion for fixing with screws is also reduced. That is, the amount of material used for forming the hinge portion is suppressed.

  Further, in the vacuum cleaner having the above-described configuration, the fastening member is provided on a side farther than the shaft portion of the holding member with respect to the lid portion, and the locking portion is provided on the holding member with respect to the lid portion. It is characterized by being provided on the side closer to the shaft portion.

  According to this configuration, it is not necessary to use a fastening member such as a screw at a location closer to the lid portion than the shaft portion of the holding member. As a result, the shape of the portion closer to the lid portion than the shaft portion of the holding member becomes relatively small, and the boss portion does not exist.

  Further, in the vacuum cleaner having the above-described configuration, a lock slider that engages with the lid portion to maintain the lid portion in a closed state with respect to the opening surface of the dust collecting container, and the lid portion of the lock slider A lock release lever that engages with the lock slider to release engagement with the lock slider, and a lock release lever that displaces the lock release lever in a direction to release engagement with the lid portion of the lock slider. And a lock release button provided integrally therewith.

  According to this configuration, since the lock release button is provided integrally with the lock release lever, the number of parts is reduced and the amount of material used for forming the lock portion of the lid portion holding those members is suppressed. .

  According to the configuration of the present invention, the amount of material used for forming the hinge part that allows the lid part to be opened and closed with respect to the dust collecting container and the lock part for maintaining the lid part in a closed state is suppressed, and the hinge part And an increase in the size of the lock portion is also suppressed. Therefore, the vacuum cleaner which can aim at suppression of the usage-amount of the material which concerns on formation of a dust collector, and suppression of the enlargement of a dust collector can be provided.

Note that two of the three screw portions 75 are disposed in the vicinity of the bottom opening surface 22 b and the lid portion 50.

  The lock slider 72 is disposed in the vicinity of the bottom opening surface 22 b and the lid 50 inside the cover member 71. The lock slider 72 is guided by the cover member 71 so as to be slidable along the circumferential direction of the dust collecting container 22 (the direction indicated by the arrow X in FIG. 11). Further, as shown in FIG. 10, the lock slider 72 includes two elongated holes 72 a through which two screw portions 75 disposed in the vicinity of the bottom opening surface 22 b and the lid portion 50 pass. The longitudinal direction of the long hole 72a is parallel to a plane including the lower edge of the bottom opening surface 22b. Thus, the lock slider 72 can be slid along the circumferential direction of the dust collecting container 22 within the longitudinal range of the long hole 72a.

  The lock slider 72 includes an engagement portion (not shown) that engages with the engagement piece 53 of the lid portion 50 in the closed state. The engaging portion is a surface of the lock slider 72 facing the dust collecting container 22 and is provided at a location corresponding to the engaging piece 53 of the lid portion 50. By sliding the lock slider 72 along the circumferential direction of the dust collecting container 22, the engaging portion is engaged with the engaging piece 53 or is disengaged. The lock slider 72 is biased in the direction in which the engaging portion maintains the engagement with the engagement piece 53 by the action of a spring (not shown).

  The lock slider 72 includes a cam follower 72b that engages with the lock release lever 73 when the lid 50 in the closed state is opened and closed. The cam follower 72 b is provided at an upper portion of the lock slider 72 and corresponding to the lock release lever 73.

  Further, the lock slider 72 includes an inclined portion 72c that comes into contact with the protrusion 54 provided in the vicinity of the engaging piece 53 of the lid 50 when the lid 50 in the closed state is opened and closed. The inclined portion 72 c is provided below the lock slider 72 and at a location corresponding to the protruding portion 54. The inclined portion 72 c is formed with an inclined surface that is inclined with respect to the circumferential direction of the dust collecting container 22.

  The lock release lever 73 has a shape extending upward from a portion corresponding to the upper portion of the lock slider 72. The lock release lever 73 is guided by the cover member 71 so as to be slidable in the vertical direction (the arrow Y direction in FIG. 11) along the axial direction of the dust collecting container 22. The lock release lever 73 includes a cam portion 73a that engages with the cam follower 72b of the lock slider 72 at the lower end thereof.

  The lock release button 74 is provided integrally with the lock release lever 73 on the upper part of the lock release lever 73. The lock release button 74 is provided to displace the lock release lever 73 in the direction of releasing the engagement of the lock slider 72 with the lid portion 50, that is, upward. A part of the lock release lever 73 including the portion of the lock release button 74 is exposed to the outside of the cover member 71 from the window portion 71a. Thereby, the lock release button 74 can be operated in the window part 71 a of the cover member 71.

  When the lock release button 74 is pushed upward in a state where the lid 50 is closed, the lock release lever 73 is displaced upward. Subsequently, the cam portion 73a of the lock release lever 73 pushes the cam follower 72b of the lock slider 72 engaged therewith. Accordingly, the lock slider 72 slides in the circumferential direction of the dust collecting container 22 against the biasing force of the spring, and the engagement between the engagement portion and the engagement piece 53 of the lid portion 50 is released. As a result, the lid 50 is opened as shown in FIGS.

  Note that when the lock slider 72 slides in the circumferential direction of the dust collecting container 22, the engagement between the engagement portion and the engagement piece 53 of the lid portion 50 is released to the protrusion 54 of the lid portion 50. The inclined portion 72c comes into contact. The lock slider 72 pushes down the protruding portion 54 in contact with the inclined surface by the action of the inclined surface of the inclined portion 72c, and opens the lid portion 50. Thereby, it is prevented that the packing 52 of the cover part 50 closely_contact | adhered to the inner surface of the lower end part of the protrusion part 43 of the partition member 40 is caught in the protrusion part 43, and the cover part 50 cannot be opened. And even if the adhesiveness of the packing 52 and the protrusion part 43 improves, it is possible to open | release the cover part 50 easily.

  As described above, the vacuum cleaner 1 is configured such that the holding member 63 of the hinge portion 60 for providing the lid portion 50 so as to be openable and closable with respect to the bottom opening surface 22 b of the dust collecting container 22 includes the screw portion 64 and the locking portion 65. Since it is attached to the outer peripheral surface of the dust collecting container 22, the number of fastening members such as screws 64a is reduced. Therefore, the hinge portion 60 itself becomes relatively small, and the boss portion for fixing with screws is also reduced. That is, the amount of material used for forming the hinge portion 60 can be suppressed.

  Further, in the vacuum cleaner 1, the locking portion 65 of the hinge portion 60 is provided on the side closer to the shaft portion 62 of the holding member 63 with respect to the lid portion 50. It is not necessary to use a fastening member such as a screw 64a at a location closer to the portion 62. Thereby, in particular, the shape of the portion closer to the cover portion 50 than the shaft portion 62 of the holding member 63 becomes relatively small, and the boss portion does not exist. Further, according to this configuration, the length of the lid support piece 61 from the outer bottom surface of the lid 50 to the shaft portion 62 is relatively short. Therefore, the occupied area spreading outward in the radial direction of the dust collecting container 22 when the lid 50 is opened is relatively narrow. As a result, even if the mouth of the trash box is relatively small, the collected dust can be discarded without spilling outside.

  The vacuum cleaner 1 also includes a lock release lever 73 that engages with the lock slider 72 in order to release the engagement of the lock slider 72 with the cover 50 for maintaining the closed state of the cover 50.
