Abstract

PROBLEM TO BE SOLVED: To provide a vacuum cleaner for forming a rib for rectifying exhaust at a discharge port, suppressing exhaust sound by upward exhaust, silencing the sound without giving an unpleasant feeling to a user, jetting the exhaust from a lower part upwards and preventing the dust of a floor surface from being blown away. SOLUTION: A motor-driven blower 5 and a dust collecting chamber 6 are incorporated, the communicated discharge port 10 is provided on the exhaust side of the motor-driven blower 5 and the exhaust port 10 is inclined and provided by a grating 11 provided with the rib 12 for rectifying the exhaust so as to discharge the exhaust of the upper part of the discharge port 10 downwards and to discharge the exhaust under a center part upwards. Then, since the exhaust from the upper part of the discharge port 10 is turned downwards, the upward exhaust is suppressed and the exhaust sound is silenced. Also, since the exhaust from the lower part is jetted upwards, the dust of the floor surface is not blown away.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general household vacuum cleaner.

[0002]

2. Description of the Related Art A conventional vacuum cleaner will be described with reference to FIG. In FIG. 8, reference numeral 1 denotes an electric blower, and a dust collection chamber 2 communicating with the electric blower 1 is formed therein,
An air inlet 3 communicating with the dust collection chamber 2 is provided, and the electric blower 1
Is provided with an exhaust port 4 communicating with the exhaust port.
Is provided with a grid portion 5, and the grid portion 5 is provided with an angle so as to face slightly upward in a normal use state so that dust on the floor surface is not blown off due to ejection of exhaust gas, and exhaust gas is ejected upward. It is set as follows.

[0003]

However, in the above configuration, since the exhaust port is slightly upward, there is a problem that the exhaust sound at the time of use is easily heard by the user, which causes discomfort. Was. In addition, in the mold structure, when the exhaust lattice block is to be pulled out horizontally, projections appear on the core and the mold side, making it difficult to manufacture the mold. There was also a problem that the mold structure became complicated.

The present invention solves the above-mentioned problem. By forming a rib for rectifying exhaust gas in an exhaust grid portion, the direction of exhaust gas can be changed, and exhaust noise due to upward exhaust gas is suppressed, so that sound is quiet. It is possible to achieve a vacuum cleaner that can prevent dust from being blown off from the floor surface due to downward exhaust ejection, and can easily remove the exhaust lattice block and simplify the mold structure. is there.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a built-in electric blower, forms a dust collection chamber communicating with the electric blower, and communicates with the dust collection chamber. In the vacuum cleaner body provided with an intake port and an exhaust port communicating with the exhaust side of the electric blower, a lattice portion is provided at the exhaust port, and a rib is formed inside the lattice portion to rectify exhaust,
Further, the direction of the exhaust can be freely set by the arrangement of the ribs.

BEST MODE FOR CARRYING OUT THE INVENTION
A cleaner body having a built-in electric blower, a dust collecting chamber communicating with the electric blower formed therein, an intake opening communicating with the dust collecting chamber, and an exhaust opening communicating with the exhaust side of the electric blower. In the exhaust port, a grid portion is provided, and a rib is formed inside the grid portion to rectify the exhaust gas. By disposing the rib at the upper end of the grid, for example, the exhaust gas faces downward, and the exhaust gas faces upward. The sound is suppressed and noise is reduced, and the ribs are arranged at the lower end of the lattice, so that the exhaust is directed upward, so that the downward exhaust does not blow off dust on the floor.

Further, since there is no need to provide an angle in the exhaust direction, the rib can be set horizontally at the opening of the lattice and the direction of exhaust can be changed, so that the exhaust lattice block can be removed horizontally and the mold structure can be simplified.

According to a second aspect of the present invention, the direction of exhaust is changed by the arrangement of ribs formed inside the lattice portion, and exhaust at the upper portion of the exhaust port is exhausted downward, and exhaust at the center and lower portions is exhausted upward. The exhaust from the upper part of the exhaust port is directed downward so that the upward exhaust is suppressed, so that the exhaust noise can be reduced.Since the exhaust from the lower part blows upward, dust on the floor surface is not blown off. It was made.

In the invention according to claim 3 of the present invention, the direction of exhaust is changed by the arrangement of ribs formed inside the lattice portion, the exhaust at the upper part of the exhaust port is directed downward, the central part is horizontal, and the lower part is upward. By rectifying the air and concentrating the exhaust gas at the center, it is possible to prevent dust from being blown off on the floor surface, and to suppress exhaust noise due to upward exhaust gas so as to reduce noise.

According to a fourth aspect of the present invention, an exhaust port is provided above the cleaner body, the exhaust port is provided with a lattice portion, and a rib is formed inside the lattice portion to rectify exhaust gas. However, by arranging the ribs so that the exhaust direction can be discharged obliquely rearward, it is possible to prevent dust from being blown off on the floor surface, and it is also possible to suppress exhaust noise due to upward exhaust and reduce noise. It is what we did.

Further, since the rib does not need to have an angle in the exhaust direction and can be set horizontally at the lattice opening to change the exhaust direction, the rib and the exhaust lattice block can be formed without using a separate lattice part. Since it can be easily removed, the exhaust grille can have the same configuration as the main body of the vacuum cleaner, and the mold structure can be simplified.
