いうことがしばしばあつた。 Conventionally, in a vacuum cleaner dust collection amount display device, as shown in FIG. The display operation is performed by moving the pointer 103, but in this case, not only when dust accumulates in the dust collection chamber 105 in front of the primary filter 104 that collects coarse dust, but also when the Main filter 10
Even when the 6 was clogged, the display device operated, and when I tried to throw out the garbage, I often found that there was no garbage at all.
本発明は上記従来の欠点を解消するもので、以

Reference numeral 5 denotes a support frame that holds a main filter 7 for collecting fine dust that is detachably inserted into the rear opening 6 of the dust collecting box 4, and is provided with packing 8 for air tightness on the outer periphery. 9
1 is a primary filter for collecting coarse dust disposed between the main filter 7 and the dust collection chamber 10; 11 is an intake hole provided in front of the dust collection box 4; 12 is a dust collection box handle 13; An indicator pipe inserted into the interior, one end of which is connected to an elbow A15 that takes out the pressure P1 at the front of the electric blower 2 through a through hole 14 provided in the support frame 5, and the other end has a through hole. A lid 16 is fitted and communicates with the atmosphere. A stopper 17 having a hole 17a is provided in the middle of the indicator pipe 12, and a pressure intake port 18 is provided near the stopper 17 on the atmospheric communication side.
is provided, and dust collection box 4 is installed by elbow B19.
It communicates with the pressure P 2 between the primary filter 9 and the main filter 7 inside. 20a and 20b are pointer A and pointer B which are biased to the left by spring A21a and spring B21b, pointer A20a is in close contact with the stopper 17 at its outer periphery, and pointer B20b is in close contact with the lid 16 at its outer periphery. ing. 22 is the dust collection box handle 13
This is the air intake port located at the front. 23 is a main body handle, 24 is a front wheel, and 25 is a rear wheel.
以上の構成において、第４図のように集塵室１

ことができる。 In the above configuration, the dust collection chamber 1 is
When dust accumulates in the 0 and the ventilation resistance increases, the difference between the pressure P 2 behind the primary filter 9 and the atmospheric pressure P 3 increases, and the pointer B20 b changes to the pressure difference P 3 -.
A force F b corresponding to the product of P 2 and the area S b of the through hole of the lid 16 fitted to one end of the indicator pipe 12 is applied. Therefore, by appropriately setting the load b when installing the spring B21 b , the pressure difference becomes F b > b .
When P 3 -P 2 occurs, the pointer B20b moves against the force of the spring B21b , so it is possible to know how much dust has accumulated in the dust collection chamber 10, and to inform the user when it is time to throw away the garbage. On the other hand, if the main filter 7 becomes clogged even when there is not much dust accumulated in the dust collection chamber 10, such as when a large amount of fine dust is sucked in, the pressure difference between the front and rear of the main filter 7, P 2 and P 1 becomes larger, and the pointer A20 a becomes the pressure difference P 2 as shown in Figure 5.
- A force F a corresponding to the product of P 1 and the area S a of the hole 17a provided in the stopper 17 is applied. Therefore,
By appropriately setting the load a when installing the spring A21 a , when a pressure difference P 2 - P 1 such that F a > a occurs, the pointer A20 a moves against the force of the spring A21 a , so the main filter It is possible to know the clogging state of the main filter 7, and by removing dust from the main filter 7, cleaning can be continued, and there is no need to check the accumulation of dust in the dust collection chamber 10 each time. If the dust removal device of the main filter 7 is set to work in conjunction with the operation of the pointer A20a , the vacuum cleaner can be used continuously without requiring any human intervention.
以上の説明から明らかなように、本発明による

その効果は大きい。 As is clear from the above description, in the vacuum cleaner display device according to the present invention, one pipe and two
A pair of pointers and a spring that biases the pointers separately display the amount of dirt accumulated in the dust collection chamber and the clogging of the main filter, allowing you to accurately see how much dirt has accumulated and correctly indicate when it is time to throw away the garbage. At the same time, since you can see the clogging status of the main filter, you can be notified when it is time to remove dust from the main filter, saving you the trouble of disposing of the garbage only when there is no accumulation of dust.
The effect is great.
