Problems solved by technology

Therefore, in the above-mentioned former setting, it becomes difficult to correct the dust and the number of pulses of relatively small particles judged by the pulse width
[0015] In addition, the integration circuit is used to convert the level (voltage) of the detection part signal, and the amount of dust passing through the detection part is detected according to the level. In order to periodically discharge the integration circuit, the light emitting part must be turned on and off in a predetermined cycle. luminescence, failure to do so may hinder dust detection
[0016] As mentioned above, until now, there has been comparative characteristics of dust of a certain size, and for dust of various particle sizes including fine dust, it has not been possible to perform appropriate reporting according to the size and type of dust, or to report the size and type of dust. report subject

Embodiment approach 1

[0047] First, use Figure 1 to Figure 5 A first embodiment of the present invention will be described.

[0048] Hereinafter, the same reference numerals are attached to components having the same configuration as conventional ones, and description thereof will be omitted.

[0049] figure 1 It is a control block diagram of the electric vacuum cleaner reporting device in Embodiment 1 of the present invention.

[0050] exist figure 1 Among them, the light emitting unit 20 is composed of an infrared light emitting diode or the like. The light receiving unit 521 is composed of a phototransistor and the like. According to the dust passing between the two, a signal Vs corresponding to the dust is output.

[0051] The first amplification unit 30 is composed of an operational amplifier and the like, and amplifies the detection unit with a predetermined first amplification factor (refer to Figure 10 ) 22 output signal Vs. The first amplifying unit 30 has an amplifying function...

Embodiment approach 2

[0082] Below, use Figure 6 and Figure 7 A second embodiment of the present invention will be described. In addition, components having the same configuration as conventional components are given the same reference numerals, and their descriptions are omitted.

[0083] Figure 6 It is a control block diagram of the notification device of the electric vacuum cleaner in Embodiment 2. The difference from Embodiment 1 is that, based on the dirt levels judged by the first dust amount judging unit 37 and the second dust amount judging unit 38, the composition of the dust passing through the suction flow path is shown in Table 2, and it is judged Dust determined from five types of dust type 1 to dust type 5 constitutes the determination unit 50 . In addition, in the notification control part 40, the notification by the notification part 11 can be controlled according to the structure judged by the dust composition judgment part 50. in addition, Figure 7 shows the configuratio...

Embodiment approach 3

[0094] Below, use Figure 8 A third embodiment of the present invention will be described.

[0095] In addition, the same code|symbol is attached|subjected to the component of the same structure as conventional, and description is abbreviate|omitted.

[0096] Figure 8 It is a figure which shows the structure of the reporting part 11 in Embodiment 3 of this invention, The structure other than that is the same as Embodiment 1.

[0097] exist Figure 8 Among them, the symbol 71 is displayed by the dirt level judged by the first dust amount judging part 37 or the second dust amount judging part 38, is composed of LEDs, and is a dirt level 1 display showing dirt level 1. Likewise, the soil level 2 display 72 shows the soil level 2, the soil level 3 display 73 shows the soil level 3, and the soil level 4 display 74 shows the soil level 4.

[0098] If the report control section 40 has a dirt level of 0, all of the displays will be extinguished. For the dirt levels judged by the ...

Abstract

This notification device of the vacuum cleaner is provided with a first dust detecting means, a second dust detecting means, a state determination means determining the presence / absence or the state of the dust to be sucked based on a first dust detecting signal detected by a first dust detecting means and a second dust detecting signal detected by a second dust detecting means, a notification means, and a notification control meanscontrolling the notification of the notification means based on information determined by the state determination means. This constitution can detect the dusts with different dimensions according the the dimension of dust and execute the appropriate notification according to the dimension, constitution, and type of the dust.

Description

technical field [0001] The present invention relates to an reporting device for displaying dust conditions in general household or dedicated electric vacuum cleaners, and includes accessories such as floor suction tools used in electric vacuum cleaners. Background technique [0002] Figure 9 A schematic configuration diagram showing a conventional electric vacuum cleaner. [0003] exist Figure 9 Among them, the electric blower 2 is built in the center of the electric vacuum cleaner to generate suction force. The hose 3 has an operation part 4 for operating the operation mode of the electric blower 2 according to different inputs (supplied electric power). The suction tool 8 comes into contact with the surface to be cleaned to suck in dust and the like. The dust collecting chamber 6 accumulates the sucked dust. The hose 3 and the dust collection chamber 6 are connected through the suction port 7 provided on the main body 1, and the suction flow path is formed by the dust...
