欠点がある。(B) Conventional Techniques As a technique for making the present invention light, for example, US Pat.
Japanese Patent No. 3,167 and Japanese Patent Application Laid-Open No. 61-61948 show an electric vacuum cleaner in which suction air containing dust is blown against water in a water tank to separate the dust. In this conventional technique, the water separator attached to the intake side of the electric blower separates the water splashed by the blow of the intake air from the intake air, but this water separator alone ensures the water. Separation is difficult, and the water separator interferes with the amount of suction air, resulting in poor suction efficiency.

り込むことがない。With the above structure, the cylindrical water tank (19) is housed in the lower part of the main body case (1), and the suction hose (26) is connected to the connecting tubular portion (28) of the suction port (27). When the electric blower (7) is operated, suction air containing dust is sucked into the cylindrical water tank (19) from the suction port outlet (30) of the suction port (27), and the suction port outlet (30) is The intake air is opened laterally in the circumferential direction of the water tank (19), so that the suction air forms an inner circumferential wall (19a) between the inner circumferential wall (19a) and the tubular wall (32) of the water tank (19). Flows in a vortex along this, and this suction air is blown against the water (20) and the water (20)
As the water rotates, the centrifugal force of the rotating water (20) lowers the central portion (B) and the outer peripheral portion (C) as shown in FIG.
Rotate in a spiral shape so that the height becomes higher to form a concave water surface (A ′) having a low central portion (B). Then, the suction air is mainly blown to the water (20) in the outer peripheral portion (C),
Dust is separated by contact with water (20), and dust (2)
0) Store in. And this spray of air mainly produces water droplets (35) ... From the water (20) in the outer peripheral portion (C), but these water droplets (35) ... It collides with 32a) and falls into the water (20), and the communication port (25)
Does not get into the electric blower (7). Further, a part of the sucked air is also sprayed onto the water (20) in the central portion (B), but the amount of spraying is equal to the water (2) in the outer peripheral portion (C).
Since it is less than the amount sprayed onto the water (0), the amount of water droplets generated is also very small, and since the distance between the water (20) in the central portion (B) and the electric blower (7) is large, the amount of water droplets generated It does not reach the electric blower (7) and does not enter the electric blower (7).

る。As shown in FIG. 4, coarse dust is collected in advance by inserting a dust collection box (52) between the connection pipe (50) of the suction hose (26) and the floor suction device (51). However, only fine dust may be collected in the water (20). The upper surface opening (53) of the dust collection box (52) can be opened and closed by an opening / closing lid (55) having a clamp hook (54) and a bag-like filter (56) such as a paper bag filter or a cloth bag filter is internally provided. It is detachably stored. Therefore, coarse dust should be removed from the dust collection box (5
2) The bag-shaped filter (56) collects in the inside, and only the fine dust is guided to the water tank (19) and collected by the water (20), so that the fine dust can be collected efficiently. it can.

あるから製造費用も低減する。(G) Effect of the Invention The present invention is configured as described above, and particularly in an electric vacuum cleaner configured to collect dust with water, the suction hose connection suction port of the cylindrical water tank is opened in the circumferential direction. Since the water tank has a cylindrical wall that surrounds the communication port to the electric blower, the suction air containing dust flows in a swirling manner in the water tank, and the accumulating air The generated water flows spirally so that the central part is low and the outer peripheral part is high, and the water droplets generated on the outer peripheral part due to the blowing of the suction air are blocked by the cylindrical wall and do not enter the electric blower. Therefore, water and suction air can be separated without a water separator, and the suction scene can be sufficiently taken and the suction efficiency can be increased. Moreover, since the tubular wall has a simple structure in which it is formed downward from the upper wall of the cylindrical water tank, the manufacturing cost is reduced.
