Description

The present invention relates to an electric vacuum cleaner provided with a dust collecting container having a lid for discarding the collected dust.

In recent years, vacuum cleaners equipped with a cyclone-type dust collector that separates relatively large dust by centrifugal force by swirling the sucked air in the dust collection container and deposits it on the bottom of the dust collection container have become widespread. , The prior art relating thereto is disclosed in Patent Documents 1 and 2.

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

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

Inside the dust collecting container, an inner cylinder having an airflow outlet opened coaxially is arranged on the peripheral surface. A partition member is attached to the inner cylinder to form an air flow path between the inner cylinder and the inner surface of the dust collecting container and partition the inside of the dust collecting container up and down. Above the inner cylinder, a circular filter in a plan view is arranged to cover the opening surface on the upper surface of the dust collecting container. The downstream side of the airflow of the filter communicates with the electric blower.

In the vacuum cleaner having the above 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 inflow port through the extension pipe and the connecting hose. The air that has flowed into the dust collection container swirls in the dust collection container, and large dust is separated by centrifugal force and accumulated at the bottom of the dust collection 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 flowing out of the dust collector passes through the electric blower and is exhausted to the outside. As a result, the surface to be cleaned can be cleaned.

A lid is provided at the opening surface on the bottom surface of the dust collection container. The lid is provided so as to be openable and closable with respect to the opening surface on the bottom surface of the dust collecting container. By removing the dust collecting container from the dust collecting device and opening the lid, the dust accumulated in the dust collecting container can be discarded. The lid is opened downward by operating the unlock button, and the dust in the dust collecting container falls with the opening.

Since the lid of the vacuum cleaner having the above configuration opens downward with respect to the dust collecting container, there is a high possibility that a large impact will be applied to the hinge portion connecting the dust collecting container and the lid due to the action of gravity. As a result, it is necessary to firmly configure the hinge portion. Therefore, the conventional vacuum cleaner forms a hinge portion having a relatively large structure that can withstand an impact, and the hinge portion is fixed to the outer peripheral surface of the dust collecting container with a screw that is a fastening member. As a result, there is a problem that the hinge portion itself becomes relatively large and the boss portion for fixing with screws also becomes large, so that the material for forming the hinge portion increases. Then, as the size of the hinge portion increases, there is a risk that the dust collector also increases in size.

Further, in the above-mentioned conventional vacuum cleaner, since the unlock button on the lid is configured independently of the other members constituting the lock device, the number of parts increases and the material related to the formation of the lock device is increased. There was an increasing problem. Then, as the size of the lock device increases due to the increase in the number of parts, there is a risk that the dust collector also increases in size.

The present invention has been made in view of the above points, and provides an electric vacuum cleaner capable of suppressing the amount of material used for forming a dust collector and suppressing the increase in size of the dust collector. The purpose is.

The vacuum cleaner according to one aspect is a cyclone type vacuum cleaner, and includes a main body portion, a dust collecting container, a lid portion, and a protruding portion.

This prevents the packing 52 of the lid portion 50, which is in close contact with the inner surface of the lower end portion of the protruding portion 43 of the partition member 40, from being caught by the protruding portion 43 and making it impossible to open the lid portion 50. Then, even if the adhesion between the packing 52 and the protruding portion 43 is improved, the lid portion 50 can be easily opened.

As described above, in the vacuum cleaner 1, 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 22b of the dust collecting container 22 has the screw portion 64 and the locking portion 65. Since it is attached to the outer peripheral surface of the dust collecting container 22 by using it, 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 also decreases. That is, the amount of material used for forming the hinge portion 60 can be suppressed.

Further, in the vacuum cleaner 1, since 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, the shaft of the holding member 63 is provided with respect to the lid portion 50. It is not necessary to use a fastening member such as a screw 64a at a position closer to the portion 62. As a result, the shape of the portion of the holding member 63 closer to the shaft portion 62 with respect to the lid portion 50 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 62 is relatively short. Therefore, the occupied area that extends outward in the radial direction of the dust collecting container 22 when the lid portion 50 is opened becomes relatively narrow. As a result, even if the mouth of the trash can is relatively small, the collected dust can be disposed of without spilling to the outside.

Further, the electric vacuum cleaner 1 includes a lock release lever 73 that engages with the lock slider 72 to release the engagement of the lock slider 72 with the lid portion 50 for maintaining the closed state of the lid portion 50, and this lock is provided. The release lever 73 is integrally provided with a lock release button 74 for dislocating the lock release lever 73. As a result, the number of parts can be reduced, and the amount of material used for forming the lock portion 70 holding those members can be suppressed.

Then, according to the configuration of the above embodiment of the present invention, the hinge portion 60 for opening and closing the lid portion 50 with respect to the dust collecting container 22 and the lock portion 70 for maintaining the lid portion 50 in the closed state are formed. The amount of such material used is suppressed, and the enlargement of the hinge portion 60 and the lock portion 70 is also suppressed. Therefore, it is possible to provide the vacuum cleaner 1 capable of suppressing the amount of material used for forming the dust collector 20 and suppressing the increase in size of the dust collector 20.

Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to this, and various modifications can be made without departing from the gist of the invention.

For example, the vacuum cleaner 1 is a so-called canister type in which the suction port body 5 is connected to the main body 2 containing the electric blower 6 via the connection hose 3, but the suction port 5 is integrally provided in the main body 2. It may be a vertical vacuum cleaner.
