Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a vacuum cleaner whose dust collection part can be seen from outside the machine.

(b) Prior Art For example, Japanese Utility Model Publication No. 41-22873 discloses a vacuum cleaner that cleans by sucking in dust mixed with moisture as it is. This vacuum cleaner uses a separation mechanism attached to the main body of the vacuum cleaner to separate the inhaled dust and moisture from the air, but it is unclear how much and what kind of dust and moisture accumulates within this separation mechanism. There is no way to check whether the wastewater is being cleaned properly, making it difficult to decide when to throw out trash or drain water.

(c) Problems to be solved by the invention This invention can reliably store moisture and dust without making the dust collection case undesirably large, and furthermore, it can prevent dust and dust from entering the dust collection case. This allows the degree and type of water retention to be easily confirmed from the outside.

(d) Means for Solving Problems The vacuum cleaner of the present invention has a main body containing a fan motor and a power source, a suction port at the tip, and a substantially cylindrical vacuum cleaner that is removably attached to the front of the main body. dust collection case, and a moisture/water container installed inside the dust collection case.
In the vacuum cleaner equipped with a dust separator, moisture and dust are stored by a protruding wall provided to protrude inward from the bottom of the dust case from below the tip suction port and an inner wall at the bottom of the dust case. The present invention is characterized in that a dust part is formed, the dust collection case is made of a transparent material, and a water level line for notifying maximum storage is provided on the dust collection case.

(E) Effect Due to the rotation of the fan motor, dust mixed with moisture is sucked into the dust collection case along with the suction air.
The water is separated from the suction air by a moisture/dust separator and stored in the dust collection section of the dust collection case. The degree and type of accumulated dust and moisture can be confirmed from outside the machine through a transparent member in the dust collection section. Furthermore, when the vacuum cleaner is placed horizontally on the floor or the like, if the stored moisture does not reach the water level, the moisture will not flow back out of the machine from the suction port when the vacuum cleaner is in use.

(F) Embodiment The present invention will be described below using a hand-held vacuum cleaner as an embodiment.

(1) is the main body of the vacuum cleaner, with a handle 2 on the upper rear surface,
It has an intake port 3 on the front wall, a switch operation button 4 on the top, and an exhaust port 5 on the side. Inside, there are a rechargeable battery 6 as a power source, a fan motor 7, and a power switch. It houses electrical equipment such as (not shown). The fan motor 7 has a fan casing (not shown) having a waterproof structure to prevent other electrical components from getting wet.

Reference numeral 8 denotes a light-transmitting synthetic resin dust collection case that is detachably attached to the front part of the main body 1 by a clamp mechanism or the like, and has a fitting opening 9 in the rear part that fits into the front wall surface, and has a front part. It has an elongated cylindrical shape that gradually becomes thinner toward the front end, and has a tip suction port 10 at the front end, and the suction tube 11 is connected to the tip suction port 10.
It is formed to extend inward from the inside. Therefore, suction cylinder 1
1 and the bottom inner wall of the dust collection case 8,
It forms a dust storage section that can store dust and moisture. Further, the outlet 11a of the suction cylinder 11 has a rubber check valve 12 that can be opened and closed. Maximum storage notification water level lines 13 are horizontally carved on both left and right sides of the dust collection case 8 to define the upper limit of the storage water when the vacuum cleaner is placed in a horizontal state. The water level line 13 indicates that when the vacuum cleaner is tilted as shown in FIG.
The amount of water that does not become higher than a, that is, the amount of water that does not cause the stored water to flow back from the suction tube during use, is carved at the water level that is stored when the vacuum cleaner is placed in a horizontal position.

Reference numeral 14 denotes a moisture/dust separator that separates moisture and dust from intake air, and is detachably housed in the dust storage case 8 so as to cover the intake port 3 of the main body 11. This separator 14 has a cylindrical body 16 extending from the center of a filter housing 15 that houses a filter, and has a front end surface 16a for separating moisture/dust and suction air at the front end thereof, and an air passage hole 17 on the peripheral surface. They each have their own.

With the above configuration, when the user holds the handle 2 of the main body 1 and presses the switch operation button 4, the fan motor 5 rotates at high speed. When cleaning dust mixed with moisture, the moisture and dust are sucked in from the tip suction port 10 along with the suction air. The moisture and dust sucked into the dust storage case 8 collide with the front end surface 16a of the cylinder 16 of the moisture/dust separator 14, the suction speed is reduced, and the moisture and dust sucked into the dust storage case 8 are separated from the suction air.
It falls inside and is stored. And this storage state,
The type of moisture and dust can be visually confirmed from outside the machine because the dust collection case 8 is made of translucent synthetic resin. The intake air is exhausted from the air passage hole 17 through the filter, the intake port 3, the fan casing inside the main body 1, and the exhaust port 5 to the outside of the machine.

When not in use, the vacuum cleaner is placed horizontally on the floor, etc., and in this state, the accumulation of moisture and dust can be visually confirmed from outside the machine. If you visually check that it is lower than 13, you can confirm that you can skip the draining work and use it next time. Therefore, it is possible to accurately determine when to dispose of garbage and drain water.
Moreover, moisture does not flow back from the tip suction port 10 during use.

In addition, when disposing of garbage or draining water, remove the dust collection case (G) 8 from the main body 1 and remove the moisture from the dust separator 1.
4 from the dust collection case 8.

According to the present invention, moisture and dust are stored by the protruding wall that protrudes inward from below the tip suction port of the almost cylindrical dust case and the bottom inner wall of the dust case. Since a dust collection section is formed, moisture and dust can be reliably stored without undesirably increasing the size of the dust collection case.

Furthermore, since the dust collection case is made of a translucent material, the degree and type of dust and moisture stored inside the dust collection case can be easily seen from outside the machine, making it possible to efficiently remove dust. In addition to being able to perform tasks such as throwing away water and draining water, even when the vacuum cleaner is placed horizontally, you can accurately know when it is time to remove the accumulated water, and when using the vacuum cleaner, water will flow back out of the machine from the suction port at the tip, preventing cleaning floors, etc. There is no risk of contaminating the
