Description

[Detailed description of the invention] This invention relates to a vacuum cleaner in which a main body case is detachably connected to the upper part of a dust collection case. This is particularly effective for handheld devices.

The present invention will be explained below with reference to the illustrated embodiment. In the figure, 1 is a dust collection case, which has a side wall 2A at the lower part of the front side and has a recessed part 2 extending to the bottom surface IA of the case 1. A suction port 3 is provided on the bottom surface of the portion 2.

Reference numeral 4 designates a check valve made of an elastic body provided at the suction port, and reference numeral 5 designates a pre-filter 16 which is a filter having a large number of folds, and a frame body 7 made of synthetic resin is integrally formed around the periphery.

Reference numeral 8 denotes a dust removal body, which is slidably held by a guide pin 9 and a guide rib 10 supported between the frame bodies 7, and has a pair of vibration imparting bodies on the lower surface that abuts against the top of the filter 6 to impart vibration. 11 is installed.

Reference numeral 12 denotes a gasket attached to the frame body 7.

13 is the main body case, and there is a gold plate 14 on the top of the dust collection case 1.
are removably connected.

This main body case consists of a pair of synthetic resin cases 13a and 13b divided into left and right sides, and has locking portions 15 on the lower front and rear surfaces.
A hook 16 provided on the front side of the dust collection case 1 engages with the metal fitting 14 and a locking part 17 on the rear side, respectively.

The hook 18 is a U-shaped grip formed by recessing the lower back side of the metal 14 so as to communicate with the concave portion 2, and the hook facilitates the operation of the metal 14.

Reference numeral 19 is a compression spring with a hook of metal 14.

20 is an electric blower, 21 and 22 are anti-vibration rubbers, 23 are ribs for forming air passages protruding from the inner surfaces of the cases 13a and 13b, and 24 is a sound deadening material, a part of which is sandwiched between the ribs 23. It is installed.

25 is a plug for connecting a power cord, 26 is a main body switch, 27 and 28 are bosses for mounting screws 33 when assembling the cases 13a and 13b, and 29 is a handle.

Openings 30 are formed in the side surfaces of the cases 13 a and 13 b facing the bosses 28 located on both sides of the handle, and the bosses 28 are used as attachment parts for both ends of the band 31 .

32 is an exhaust port. In the above configuration, the plug 25
When the power cord is connected to the main body switch 26, the electric blower 20 is driven, and dust is sucked into the dust collection case 1 through the suction hose (not shown) connected to the suction port 3, The purified air passes through the pre-filter 5 and the filter 6, and is discharged from the exhaust port 32 through the air path as shown by the arrow in FIG.

The dust is filtered by the pre-filter 5 and the filter 6 and collected in the dust collection case 1, and the exhaust noise is absorbed by the sound deadening material 24 and reduced.

When uncoupling the dust collection case 1 and main body case 13,
Insert your fingertips into the back side of the U-shaped grip 18, grip this grip, and press the hook 14 with your thumb.
and the locking portion 15 are disengaged, and the main body case 13 can be separated from the dust collection case 1.

Conventionally, in a vacuum cleaner in which a dust collection case and a main body case are vertically combined, the suction port is provided on the side of the dust collection case flush with another surface or protruding from the other surface. Therefore, the hook that connects the dust collection case and the main case is very difficult to operate because there is no place for your fingers to get caught when operating the handle, and the suction port gets in the way. It was common to have a separate handle for carrying the item.

However, according to the present invention, which differs from the above configuration, a concave part having a side wall and extending to the bottom of the dust collecting case is provided on the side surface of the dust collecting case, and a suction port is provided at the bottom of the concave part, and The hook has a metal part positioned above the recess, and the upper part of the suction port is recessed so as to communicate with the recess, and the hanger has a grip part formed at the lower part of the metal, so that it can be used for dust collection. When connecting or separating the case and the main case, the latch can be operated by grasping the grip part, and the suction port formed on the side of the case does not get in the way at all, making the operation extremely easy. It's easy to do.

In addition, since a concave portion is formed at the bottom of the grip, when gripping the grip, you can comfortably hold the grip without worrying about your fingertips getting caught. Since it can also be used as a handle for disposing of dust, there is no need to provide a separate handle for carrying the dust collection case.

Further, according to the present invention, since the recessed portion in which the suction port is provided has a side wall, the connecting portion between the hose body and the suction/port connection portion connected to this hose body is located within the recessed portion. If the hose is connected to the suction port, even if the hose is extremely bent, the hose body will come into contact with the side wall of the recess, and external force will not be applied to the easily damaged connection between the hose body and the suction port connection. It becomes less.

In addition, since the concave portion extends to the bottom of the dust collection case, even though the dust collection case has a concave portion and a concave portion for forming a grip, the metal There is no need to make the type complicated.

Furthermore, according to this invention, the concave portion extends to the bottom of the dust collection case, but since it has a side wall, the lower part of the side wall can also be used as the base of the vacuum cleaner. Therefore, even though the vacuum cleaner is provided with a recess that extends to the bottom of the dust collection case in order to achieve the above-mentioned effects, the vacuum cleaner becomes unstable when placed on the base. Nor.
