Description

[Detailed description of the invention] The present invention relates to a vacuum cleaner.

Conventionally, when discarding dust from inside the dust case, the dust adhering to the filter was dropped and then the dust was thrown away, and the dust adhering to the inside of the dust case was removed by applying vibration to the dust case from the outside. There is something. For example, as described in Japanese Utility Model Publication No. 51-26933, a collision element biased by a compression spring is provided in the dust collection case, and an operator connected to the collision element is projected outside. By gripping this operator, pulling it outward, and then releasing your hand, the compression spring returns and causes the collision element to collide with the dust collection case, generating vibration. At the same time, it also removes dust from the internal filter. With this type of structure, the controls protrude outside, making it difficult to handle as a vacuum cleaner.Furthermore, there are problems such as damage to furniture due to collisions during cleaning, and furthermore, the operation condition is constant. Because it is not the same, the impression force is not constant,
If the stamping force is too strong, the filter may fall off or become misaligned inside, which is troublesome. In addition, in the case of a dust case in which a dust disposal bag is attached to the opening for dust disposal, it is possible to

When the case is hit or shaken, the force is too strong and it may fall off, scattering dust, which is extremely unsanitary and troublesome to clean up afterwards. This invention is a hygienic electric vacuum cleaner that can easily stamp a dust case with a substantially constant force and dispose of it without leaving any dust attached to the inner surface of the dust case.
The purpose is to remove the machine.

In this invention, a dust case that houses a filter and has an opening for disposing of dust that can be opened and closed on one side is detachably connected to a main body case that houses an electric blower.
A side surface of the dust case connected to the main case,
The dust case is characterized in that it has a rotatable disc-shaped hitting body that has an operation part that is operated from the outside and that elastically hits a hitting part provided on the dust case to apply vibrations. It is. Therefore, by operating the operation part and moving the striking body, vibration is imparted to the dust case, and the dust can be dropped from the opening surface without leaving dust attached to the inner surface of the dust case. The dust case is struck elastically, but the force can be set at a nearly constant level. Therefore, even if the filter falls off against one's will or a dust bag is installed, the dust bag will not be removed. In addition, by connecting the dust removing body to the striking body, the structure can be simplified and downsized by sharing components including the operation part, and the dust case can be removed with one operation. The structure is such that dust removal and filter dust removal can be performed at the same time. An embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes a main body case that houses an electric blower 2. A dust case 3 connected to this main body case 1 has an inlet 4 and a dust collection chamber 5 formed therein. A bottom lid 7 is sealed by a backing 8 and is attached so as to be openable and closable.

The dust case 3 is removably connected to the main case 1 by engaging the rear end of the bottom cover 7 with the locking recess 9 of the main case 1 and engaging the upper clamp 10 with the main case 1. It is something. A compression plate 11 for compressing dust is provided in the dust collection chamber 5 so as to be movable up and down, and a filter frame 12 is sealed and detachably housed in a backing 13.

A net filter 14 is attached to the front of the filter frame 12! A filter 15 made of sponge and a filter 16 made of filter paper bent into a bellows shape are housed. Next, a clamp 18 for locking the bottom cover 7 in a closed state is provided on the partition wall 17 on the back side of the dust case 3, and a clamp 18 is provided in the center to hold and hold the backing 19, and a ring-shaped clamp is provided between the backing 19 and the main case 1. A rib 21 forming a style 20, and a plurality of protrusions 22 as striking parts located on the inner surface of the rib 21 are formed.

Therefore, the partition wall 17 has an opening (not shown) for ventilation.
However, a striking body 23 is provided in the center where no opening is formed.

The striking body 23 is rotatably held by the partition wall 17 and is rotatably attached to the outer circumference of the disc 26 in correspondence with the protruding piece 22. It consists of a lever 27 that has been closed. This lever 27
is urged by a spring (not shown) so that it always returns to the straight line in the radial direction of the disc 26, and its length is determined to be such that it interferes with the protruding piece 22. Then, the shaft portion 28 of the disc 26
A dust removing body 30 having a dust removing element 29 formed by a spring that interferes with the filter 16 at the tip thereof is fixed. Then,
A frame 32 made of polyethylene or the like and holding the opening edge of a dust disposal bag 31 is elastically fitted to the lower inner periphery of the dust collection chamber 5. A part of the dust disposal bag 31 is pressed against the filter frame 12 so as not to loosen. In such a configuration, by driving the electric blower 2, outside air containing dust is sucked in through the suction port 4, purified by the filters 15 and 16, and discharged from the exhaust hole 33 of the main body case 1.

When discarding dust, operate the clamp 10 to remove the dust case 3 from the main case 1. In this state, or in a state where the bottom cover 7 is opened by operating the clamp 18 and the dust disposal bag 31 is opened, the operation part 24 is grasped and the disc 26 is rotated.
As a result, on the one hand, the dust remover 29 of the dust removal body 30 vibrates the filter 16 and knocks off the dust attached to the filter 16 to prevent clogging, and on the other hand, as shown in FIG. hits the protrusion 22a of the dust case 3 and rotates backward, and as the rotation of the disk 26 progresses, it detaches from the struck protrusion 22a and returns to the neutral position with inertia, and then elastically hits the next protrusion 22b. Repeat the action of colliding with the Due to this action, dust adhering to the inner surface of the dust case 3 falls into the dust disposal bag 31. In this way, by one operation of holding and rotating the operating part 24, dust can be removed from the filter 16 and dust from the inner surface of the dust case at the same time. Furthermore, since the lever 27 hits the projection piece 22 with a force that urges it to return to neutral, the collision force applied to the dust case 3 can be made constant by determining the urging force. As a result, the filter 14.
16 and the filter frame 12, and the dust disposal bag 31 will not slide down. Lever 27
The same effect can be obtained by fixing one end of a flexible member to the disk 26, which returns to the neutral position by its own elasticity, without being biased by a spring. Then, the dust disposal bag 31 is removed from the frame body 32, its opening is tied up, and thrown away in a predetermined place, and a new dust disposal bag 31 is attached to the frame body 32, but during this time, the dust inside the dust case 3 remains. It is hygienic because the remaining dust does not fall off. Further, the dust removing body 30 and the striking body 23 are connected to the operating section 2.
4 and the disk 26 which is the main operating body, thereby simplifying the structure and making it possible to reduce the size.

Since the present invention is constructed as described above, when the operating section is operated and the striking body is rotated, the striking part of the dust case is struck, thereby imparting vibration to the dust case, and causing the inner surface of the dust case to vibrate. The attached dust can be dropped from the opening surface, and at this time, the hitting body hits the dust case elastically through the hit part, but the force can be set approximately constant, so that the hitting The force is not applied unevenly or excessively, the filter does not fall unexpectedly, and even if a dust bag is attached, the dust bag does not fall off. By connecting, the structure can be simplified and downsized by sharing components including the operation part, and the operation part does not protrude outside and does not get in the way of handling. It is possible to remove dust from the dust case and the filter at the same time by operating the device, and since the striking body is rotatable, it has good operability and the striking force is constant. .
