Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a household cleaner which detects the amount of dust in a dust bag by the amount of permeation.

[0002]

2. Description of the Related Art Conventionally, the amount of dust in a dust bag of a vacuum cleaner is detected by
The suction pressure of the vacuum cleaner was changed mechanically by using a spring to change due to the increase of dust.

[0003]

However, with this method, when the dust is like cotton dust, there are many gaps due to cotton dust even though the dust bag is full of dust, The suction pressure does not decrease so much. Therefore, the amount of dust cannot be detected and the notification cannot be made. Therefore, there is a problem that the user must use the vacuum cleaner as it is, the dust overflows the dust bag, enters the inside of the hose of the vacuum cleaner, and the user himself / herself needs to dispose of the cotton dust clogged in the hose.

In view of the above problems, it is a first object of the present invention to provide a vacuum cleaner which notifies the user of the exchange of the dust bag at an appropriate time regardless of the type of dust and improves the usability. To do.

It is a second object of the present invention to provide a vacuum cleaner capable of predicting when to replace the dust bag by displaying the amount of dust inside the dust bag regardless of the type of dust. is there.

[0006]

In order to achieve the first object, the vacuum cleaner of the present invention has a detection means for detecting the amount of dust in the dust bag by the amount of transmission, and a detection signal of this detection means for dust. There is provided a garbage bag replacement notifying means for notifying when the bag should be replaced.

Further, in order to achieve the second object, the vacuum cleaner of the present invention corresponds to a plurality of detection means for detecting the amount of dust in the dust bag by the amount of transmission and each detection signal of the plurality of detection means. And a plurality of dust amount display means for displaying the dust amount.

[0008]

In the vacuum cleaner of the present invention, the dust sucked from the floor nozzle and the hose (not shown) is stored in the dust bag,
The amount of dust passing through the detection means changes due to the dust accumulated in the dust bag, and therefore the dust bag replacement notification means notifies the time of exchanging the dust bag by the detection signal. This allows the user to know that it is time to replace the garbage bag.

Further, in the vacuum cleaner of the present invention, the dust sucked from the floor nozzle and the hose (not shown) is stored in the dust bag, and the amount of dust accumulated in the dust bag is determined by a plurality of detecting means. The amount of dust is displayed by a plurality of dust amount display means corresponding to the detection signals of the plurality of detection means. This allows the user to predict when to replace the dust bag.

It is discharged from the rear part of the main body 6 by 4.

Then, the amount of transmission between the light emitting element 1 and the light receiving element 2 changes due to the dust accumulated in the dust bag 3, so that the dust bag exchange lamp 9 is turned on by the signal and the time for exchanging the dust bag 3 comes. It is to inform that.

Next, the notification of the replacement time of the dust bag 3 will be described with reference to FIG. In the figure, 30 is a light emitting element driving means for driving the light emitting element 2, 31 is a light receiving sensitivity detecting means for detecting the light receiving sensitivity of the light receiving element 2, 32 is a change in the sensitivity detected by the light receiving sensitivity detecting means 31, It is a sensitivity change detection means for driving the dust bag exchange control means 33 when the sensitivity change occurs.

In the above structure, when dust is accumulated in the dust bag 3 and the dust bag 3 becomes full and the light of the light emitting element 1 is blocked, the output of the light receiving element sensitivity detecting means 31 changes, The sensitivity change detection means 32 determines that the sensitivity of the light receiving element 2 has changed, and drives the dust bag exchange control means 33 to turn on the dust bag exchange lamp 9.

Next, a second embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 3, 1 is a light emitting element A,
