Abstract

PURPOSE:To execute a clean trash exhausting work by providing a communicating port to communicate to a motor fan in a water tank upper cover central part, providing a suction cylinder for connecting a suction hose in an upper cover side part and providing a dust discharge cylinder closed with the lower partition wall of a main body upper case in the other side part of the upper cover. CONSTITUTION:When the suction hose is connected to a suction hose connecting port 27 and a motor fan 7 is driven, a sucked air to contain the dusts is sucked through a suction cylinder 25 into a water tank 19. Since an outlet 28 of the suction cylinder 25 is opened in a lateral direction in the circumferential direction of the water tank 19, the sucked air is blown strinkingly at a water 20, and the dusts are collected in the water 20. At such a time, a dust discharge cylinder 29 is closed by a lower partition wall 5, and thereby, the air is not sucked. At the time of exhausting the trash, the water tank 19 is taken out from a main body lower case 3, a rough dust collecting cylinder 34 is fitted to the dust discharge cylinder 29, the water tank 19 is leaningly inclined, then, the dusts and water 20 are made to flow out, and paper pieces, thread dusts, etc., are collected by the rough dust collecting cylinder 34. By the above-mentioned constitution, the dusts are exhausted without generating a hook and a choke and being propagated on the outer surface of the water tank.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a vacuum cleaner that collects dust using water stored in a water tank.

(b) Prior art As a technology prior to the present invention, for example, Utility Model Application No. 61-313
No. 51 discloses a vacuum cleaner in which dust is separated by blowing suction air containing dust onto water in a water tank.

However, in this prior art, the suction tube for connecting the suction hose is bent into an L-shape so as to open downward in the water tank, so that the dust accumulated in the water is disposed of from the suction tube. In this case, there is a risk that dust, especially coarse dust (for example, pieces of paper or thread) may become caught or clogged at the L-shaped bent portion of the suction tube, making it difficult to remove it. Further, since the communication port of the water tank to the electric blower is provided at the center of the upper surface of the water tank, there is a drawback that dust and water cannot be disposed of through the communication port.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and has a simple structure that allows dust accumulated in water to be disposed of reliably without getting caught or clogged, and also allows clean garbage disposal. The purpose is to obtain a vacuum cleaner that can perform various tasks.

(d) Means for Solving the Problems The vacuum cleaner of the present invention includes a cylindrical water tank having an upper lid and storing water, a lower case of the main body that removably stores the water tank, and an electric blower. It consists of a main body upper case built in and disposed on the upper part of the main body lower case, a communication port communicating with the electric blower in the center of the upper cover, and a communication port in the water tank in the side of the upper cover. A suction tube for connecting a suction hose having an outlet opening in the circumferential direction is provided, and a dust discharge tube is provided on the side of the pond of the upper cover and is closed by a lower partition wall of the upper case of the main body. It is a feature.

(E) Effect With the above configuration, when the electric blower is driven, the suction air containing dust flows in a spiral shape from the outlet of the suction pipe for connecting the suction hose to the inner peripheral wall of the cylindrical water tank and turns into water. The sprayed water is rotated in a whirlpool and the dust is separated by contact with the water, and the separated dust is collected in the water. At this time, the dust exhaust tube is closed by the lower partition wall of the upper case, and no air is sucked from the dust exhaust tube.

Furthermore, when disposing of garbage, water and dust are disposed of through the dust discharge tube of the cylindrical water tank. At this time, since the dust ejection pipe is straight pipe-shaped, the dust does not get caught and can be disposed of smoothly and reliably, and since the dust ejection pipe is installed on the side, the discarded dust and water can be disposed of in a cylindrical shape. The water does not flow along the outer surface of the tank, allowing for clean garbage disposal.

It has become so. Further, an annular packing 18 is fitted to the edge of the intake hole 6.

Reference numeral 19 denotes a cylindrical water tank that is detachably housed in the lower case 3 of the main body, and includes a cylindrical lower container 22 with an upper opening 21 for storing water 20 as a dust collection filter, and a lower cylindrical container 22 that covers the upper opening 22. It consists of an upper lid 23 that is attached by clamp means (not shown) or the like.

The upper lid 23 is provided with a communication port 24 in its center, which closely communicates with the intake hole 6 via the annular packing 18, and a suction tube 25 for connecting a suction hose is formed in the side thereof. The suction cylinder 25 has a suction hose connection port 27 that opens to the outside of the main body upper case 2 through the suction cylinder exposure opening 26 with cover 26a of the main body upper case 2, and also penetrates through the upper cover 23 to connect the upper cover 23. It is formed so as to communicate with the back surface side, and further has a lateral outlet 28 that opens laterally toward the circumferential direction of the water tank 19.

Further, the suction cylinder 25 is formed on the upper lid 23, so that
It is located above the water surface A of the water 20 in a stationary state.

Further, a straight dust discharge tube 29 is formed to protrude upward from the other side of the suction tube 25 that is symmetrical to the communication port 24 of the upper lid 23 . The dust discharge pipe 29 has a straight pipe shape with no bends, and has an opening 3 at its upper end when one of the water tanks is housed in the lower case 3 of the main body.

Further, numeral 34 denotes a coarse dust collecting tube which is detachably fitted and attached to the dust discharge tube 29, and has a coarse dust trap 11435 stretched over its open end.

When cleaning, when a suction hose (not shown) is connected to the suction hose connection port 27 of the suction tube 25 for connecting the suction hose and the electric blower 7 is driven, the suction air containing dust flows through the suction tube 25. The water is sucked into the water tank 19 through the water tank 19. At this time, since the lateral outlet 28 of the suction cylinder 25 opens laterally in the circumferential direction of the water tank 19, the suction air flows in a spiral shape along the inner circumferential wall 19a in the water tank 19 and flows into the water 20. The sprayed water 20 rotates in a whirlpool, and the centrifugal force of the rotating water 20 forms a concave water surface B whose outer periphery is raised as shown by the two-dot chain line in FIG. The suction air is mainly blown onto the water surface B at the outer periphery, and dust is separated by contact with the water 20, and the dust is collected and stored in the water 20. At this time, since the dust discharge pipe 29 is closed by the lower partition wall 5, no air is sucked into the dust discharge pipe 29.

Furthermore, when disposing of garbage, one of the water tanks is removed from the lower case 3 of the main body, the coarse dust collection pipe 34 is attached to the dust discharge pipe 29, and the water tank 19 is tilted, so that the dust and water 20 are removed from the dust. It flows out from the discharge @29 and is disposed of. At this time, coarse dust such as paper scraps and thread waste is collected by the coarse dust collecting cylinder 34, so the coarse dust collecting cylinder 34 can be removed and the coarse dust can be disposed of in a trash can or the like. Here, since the dust discharge pipe 29 has a straight pipe shape, even if the dust contains the above-mentioned coarse dust, it can be smoothly and reliably removed without getting caught or clogging inside the dust discharge pipe 29. Can be disposed of. Further, since the dust discharge pipe 29 is formed to protrude from the side of the upper lid 23, water and dust do not flow along the outer surface of the upper lid 23, allowing a clean garbage disposal operation.

FIG. 4 shows another embodiment of the present invention, and as shown in the same figure, a dust discharge tube 38 having a coarse dust trapping net 37 housed in the upper end opening 36a is connected to the upper lid 23. Formed separately,
By removably storing the dust discharge tube 38 in the dust discharge port 39 of the upper W23, the dust discharge tube 38 is attached to the upper lid 23.
8 may be formed upwardly. In this case, the function of the coarse dust collecting cylinder is also shared by the dust discharging cylinder 38, making it easier to use.

(G) Effects of the Invention The vacuum cleaner of the present invention is constructed as described above, and in particular, the dust discharge pipe is provided on the top cover of the cylindrical water tank separately from the suction pipe for connecting the suction hose. The dust accumulated in the water can be disposed of smoothly and reliably without getting caught or clogged in the dust discharge pipe, and since the dust discharge pipe is provided on the side of the upper lid, the discarded dust and water can be disposed of smoothly and reliably. No water flows along the outer surface of the cylindrical water tank.
Therefore, it is possible to easily dispose of garbage in a clean manner.
