Abstract

(57) [Summary] [Purpose] To detect abnormalities inside a vacuum cleaner. [Configuration] The vacuum cleaner body, which also serves as a lid, removably covers the top opening of the dust box, the bottom of the body has a suction hole, the body cover has an exhaust pipe, the body cover has a suction motor, and the body has a suction hole. A float that can open and close the hole is provided below the exhaust pipe, and a detection pipe is provided in the exhaust pipe so as to be movable up and down. ``Operation'' When the suction motor operates, dust, water, etc. are sucked into the dust box through the hose connected to the air supply port. The detection tube is lifted by the exhaust pressure and protrudes from the exhaust tube. When water accumulates above a predetermined height, the float blocks the suction hole in the main body, or when the filter becomes clogged, no suction force is applied to the suction hole, and the detection cylinder descends under its own weight. Abnormalities inside the dust box can be detected by the protrusion and retraction of the detection tube.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a wet and dry system that can detect abnormalities inside the dust box of a vacuum cleaner from the outside. This relates to a suction vacuum cleaner for use.

0002

[Conventional technology]

Conventionally, this type of suction vacuum cleaner has a dust box with an air intake port and a filter. The main body of the vacuum cleaner, which also serves as a lid, is removably placed over the surface opening, and the dust bin is placed on the bottom of the main body. There is a suction hole that leads to the box, and an exhaust port on the main body cover, so that the dust and water that is sucked out are Filtered air is collected in the dust box and released from the exhaust port.

0003

[Problem that the idea aims to solve]

The above-mentioned wet and dry vacuum cleaner has the advantage of being able to powerfully suck water and dust; When the water level in the dust box rises, water enters the main body through the suction hole and the suction mode data becomes unusable. Also, even if the vacuum cleaner falls over, the water accumulated in the dust box will flow through the suction hole to the main body side. There was a problem with the oil leaking out and damaging the motor.

0004 Furthermore, the filtration performance of the filter is affected by the deflection of the pointer installed on the main body or hand duct. However, check the scale through the meter glass to check the degree of clogging of the filter. However, an indicator that can be seen at a glance even from a distance was desired. . This invention solves the above problems and detects filter clogging from the outside. It reveals the suction vacuum cleaner that can be used.

[0005]

[Means to solve the problem]

The suction vacuum cleaner of the present invention has a dust box that is open on the top and equipped with an intake port (22) at the top of the side wall. The vacuum cleaner main body (4) is removably attached to the vacuum cleaner (2) via the filter (3). A vacuum cleaner that exhausts the dust box (2) using a suction motor (5) equipped on the body (4). A suction hole (42) provided at the bottom of the vacuum cleaner body (4) can be moved up and down. A float (7) that rises due to the buoyancy of falling water and blocks the suction hole (42) and a vacuum cleaner body (4). It fits into the exhaust pipe (56) and is retractable, and both ends are open and equipped with a retainer (63). It is equipped with a detection tube (6) that has a large diameter.

[0006]

[Action and effect]

Due to the operation of the suction motor (5), dust is drawn out through the hose (8) connected to the intake port (22). Dust, water, etc. are sucked into the dust box (2). The detection tube (6) is lifted by the exhaust pressure. and protrudes from the exhaust pipe (56). When water accumulates above a predetermined height, the float (7) is activated. If the suction hole (42) of the body (4) is blocked or the filter (3) is clogged, the suction hole (42) No gravitational force is applied, so the detection tube (6) falls under its own weight.

[0007] When the detection tube (6) is lowered, turn off the switch, remove the main body (4) and put it in the dust box ( 2) Discard the water inside or unclog the filter (3), and then put it back into the dust box. Place the main body (4) on the base (2). As mentioned above, abnormalities inside the dust box (2) can be detected by the appearance and retraction of the detection tube (6). If too much water collects and damages the motor (5), or the filter (3) is clogged, Well, you can prevent the waste of using a vacuum cleaner with weak suction power.

[0008] Also, even if the vacuum cleaner falls over while in use, it will instantly float (7) due to the suction power. is drawn toward the suction hole (42) and closes the suction hole (42). Remove the suction hole (42) from the dust box (2) before the float (7) closes the suction hole (42). The amount of water that flows out to the motor side is very small, and in order to flood the motor (5), Not enough.

【Example】

A dust box (2) with an opening on the top is fixed on the base plate (1) with casters (11). The vacuum cleaner body (4) is placed over the dust box (2). The dust box (2) has a cylindrical hose connection part (21) protruding from the upper part of the side wall. The inside is the intake port (22).

0010 The filter (3) and steel net (32) are housed in the dust box (2). . The filter (3) is attached to the dust box (2) at the opening edge of the cloth bag (30) with an opening on the top. It is formed by connecting a rubber ring (31) that covers the edge of the opening.

[0011] Steel net (32) is made by bending metal wire to form a substantially cylindrical shape. Main body (4), which is housed in the router (3) and is attached to the entire filter (3) by suction force. prevent it from coming into close contact with the bottom of the

0012 The vacuum cleaner main body (4) has a hollow main body cover (55) in the shape of a hemisphere, which is raised by a partition plate (47). Divided into two lower levels, the upper motor chamber (50) has an eccentric motor (5), and the lower suction chamber. (59) accommodates an impeller (52) attached to the rotating shaft (51) of the motor (50). The impeller (52) is a case with an opening (54) at the center of the lower surface and holes (54) at approximately equal intervals on the peripheral wall. It is housed in Sing (53).

[0013] There are many holes on the bottom plate (41) of the main body cover (55) at positions corresponding to the openings (54) of the casing. Suction holes (42) are opened, and an annular receiving seat (43) formed of an elastic material surrounds the holes. It is formed.

[0014] A float guide tube (44) is arranged below the hole group, and the guide tube (44) is connected to the bottom plate (44). It is supported by a plurality of stays (45) protruding from 1). The float guide tube (44) is open at both the top and bottom ends, and has an inward retaining flange (44) at the bottom end. 6).

[0015] A cylindrical float (7) whose upper end is closed and whose lower end is open is attached to the guide tube (44). It is fitted so that it can be moved downward. The float (7) is located concentrically with the annular receiving seat (43), The diameter of the upper surface of the float (7) approximately matches the outer diameter of the receiving seat (43). An exhaust pipe is inserted through the spherical wall of the main body cover (55) at an eccentric position of the partition plate (47). (56) is provided in a protruding manner, and a detection tube (6) is disposed on the tube so as to be movable up and down.

[0016] The exhaust pipe (56) has an annular receiving piece (57) protruding inward from approximately the center thereof, and a circular receiving piece (57) is provided on the receiving piece (57). An auxiliary tube (61) is provided concentrically with the exhaust tube (56), resulting in a double structure. A detection tube (6) is slidably fitted into 1). The detection tube (6) is open at both the top and bottom ends. , the lower end is a large diameter portion (62) that slides into contact with the exhaust pipe (56).

[0017] The boundary step between the small diameter part (61) and the large diameter part (62) of the detection tube (6) prevents the detection tube (6) from coming off (63) The exhaust pressure acts on the stepped part that also serves as a stopper, and the detection tube (6) is lifted up. The detection tube (6) protrudes from the exhaust tube (56).

[0018] However, due to the operation of the suction motor (5), air flows through the hose (8) connected to the air supply port (22). As a result, dust, water, etc. are sucked into the dust box (2). The detection tube (6) is held by the exhaust pressure. It is raised and protrudes from the exhaust pipe (56). When water accumulates above a certain height, the float ( 7) blocks the suction hole (42) of the main body (4) or the filter (3) becomes clogged. No suction force acts on the hole (42), so the detection tube (6) descends under its own weight.
