Abstract

The present invention concerns a normal vacuum cleaner wherein one end of the rotational shaft of a motor in a suction chamber has mounted thereon a blower for causing solid matter on the outside of a body to flow via an inlet port into a dust chamber and for discharging air that has flowed in together with the solid matter at an emission port of the suction chamber, and either the body is provided with a means whereby the motor can change direction in the suction chamber or else the motor is capable of forwards and backwards rotation so that the blades of the blower can selectively rotate forwards and backwards such that the vacuum cleaner autonomously performs filter cleaning and at the same time the user is prevented from touching unpleasant matter with their hands such that filter cleaning and replacement are easier for the user than hitherto.

Description

Vacuum cleaner

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of discharging solids attached to a filter and solids accumulated in a dust collecting chamber by a blower.

In a conventional vacuum cleaner, a blower chamber in which a blower is incorporated is disposed in a downstream portion of the main body, a dust collecting chamber for collecting and collecting solid matter such as dust is disposed in the upstream portion, and a connecting pipe provided at one end of the hose is detachably connected Is provided at the upstream end of the main body. And the other end of the hose is provided with a distal end pipe having a grip portion at the time of cleaning. One end of the extension pipe is detachably connected to the distal end pipe, and the other end of the extension pipe And a suction dirt port is detachably provided.

In the conventional vacuum cleaner having such a structure, when the filter is used for a predetermined period of time, the filter disposed between the blower chamber and the dust collecting chamber is adhered with the solid material, so that the vacuum is not properly formed in the dust collecting chamber. In this case, the user manually flushes the solids attached to the filter to reload or replace the filter.

Such a filter cleaning operation or a filter replacement operation causes the user to touch the object with the hand, thereby causing a problem that it is treated as a very inconvenient and troublesome operation.

In order to solve such a problem, a solid material attached to the filter is shaken into the dust collecting case by vibrating or hitting the filter by the driving source of the blower, or the filtered air flow selectively flowing back into the blower chamber is selectively backwashed, There is a suggestion to shake it off.

However, such a measure is required to manually perform a manual operation of discharging the solid matter in the dust collecting case when a certain amount of solid matter is accumulated in the dust collecting case, thereby causing the user to touch the dislike water such as dust, It is still being treated as a very uncomfortable and cumbersome task.

The present invention has a problem in solving the above-mentioned problems.

According to the present invention, a dust collecting chamber is divided into a suction chamber and a suction chamber by a partition wall provided with a flow port, and an inlet through which the object to be cleaned flows into the dust collecting chamber is provided, And a filter for filtering the solid material flowing through the inlet is provided in the dust collecting chamber and a discharge port for discharging the air introduced through the flow port in the dust collecting chamber is provided in the suction chamber, And a blower for introducing the solids outside the main body into the dust collecting chamber through the inlet and discharging the air introduced together with the solids into the discharge port of the suction chamber, And the motor is provided with means for enabling the motor to be rotated in the forward / reverse direction The wings of the blower can selectively address the above problem by making it to be rotated forward and reverse direction.

According to the present invention, the vacuum cleaner can perform the filter cleaning by itself, and the user does not touch the object with the hand by the user, It can be facilitated.

A solid material outside the main body 4 is introduced into the dust collecting chamber 5 through the inlet 7 at one end of the rotary shaft 11 of the motor 10 and the air introduced together with the solids is discharged to the discharge port And a blower 110 for discharging the air to the air conditioner 8 is mounted.

The blower 110 is provided with vanes capable of inducing fluid movement from the inlet 7 toward the discharge port 8.

The motor 10 is mounted on a turntable 12 rotatably mounted on the bottom of the suction chamber 6. One end of a posture change shaft 13 having a rotation center on the rotation center axis S of the turntable 12 is fixed to the motor 10 and the other end of the posture change shaft 13 is fixed to the main body 4 And is fixed to the handle 14. As shown in Fig.

The handle 14 is provided at one end thereof with a protruding and retracting pin 16 elastically protruding and retracting. When the blower 110 is facing the flow passage 2 and facing the outlet 8 A groove 15 into which the protruding and retracting pin 16 is inserted is formed in a portion of the main body 4 which faces at the position of the handle 14 when the protruding and retracting pin 16 is inserted.

The electric vacuum cleaner 1 configured as described above can be operated as follows.

1. Cleaning the outside of the cleaner (see Figure 1)

When the motor 10 is operated after turning the handle 14 so that the blower 110 faces the flow port 2, the blower 110 is operated to move the blower 110 to the suction chamber 6 A negative pressure is formed so that the solids at the bottom outside the main body 4 are introduced into the dust collecting chamber 5 through the inlet 7 through a suction tube not shown, The air that has passed through the filter 50 passes through the flow port 2 and flows through the suction chamber 6 and the discharge port 8 to the main body 4 ).

2. When the filter 50 is cleaned (see Fig. 2)

When the motor 10 is operated after turning the handle 14 so that the blower 110 faces the discharge port 8, the blower 110 is operated so that negative pressure is applied to the suction chamber 6 The outside air outside the main body 4 flows into the suction chamber 6, the flow port 2 and the dust collecting chamber 5 through the discharge port 8 and the outside air introduced into the dust collecting chamber 5 flows into the suction chamber 6, The solids adhering to the filter 50 are easily separated from the filter 50 while passing through the filter 50 and at the same time the solids accumulated in the dust collecting chamber 5 are discharged out through the inlet 7 .
