Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a suction port body for a vacuum cleaner.

BACKGROUND ART Conventionally, there exists a suction port body in which a rotating brush and a turbine are connected and housed in a main body that runs on a floor surface, and the rotating brush is selectively rotated by adjusting the amount of air blown to the turbine. However, such a device can only be used in two ways: one is to rotate the rotary brush to clean line types, and the other is to keep the rotating brush stationary to clean hard floors such as tatami mats. .

The present invention has been made in consideration of these points, and an object of the present invention is to provide a suction port body for a vacuum cleaner that can be used for multiple purposes.

This invention provides a main body that is formed to freely communicate with a central ventilation passage that houses a turbine and a brush chamber with an opening at the bottom that houses a rotating brush through a through hole, and adjusts the amount of air that blows onto the turbine using an air passage switching plate. The turbine is selectively rotated together with the rotary brush, thereby causing the rotary brush to rotate or stop depending on the cages on the floor. A side ventilation passage connected to one side of the central ventilation passage is provided, and the shutter provided at the connection between the side ventilation passage and the central ventilation passage is opened by the sliding operation of the air passage switching plate. Position the hinge of the KL in the front so that the free end opens towards the connection to the vacuum cleaner at the rear.This allows the dust near the wall to be sucked in locally with a strong dust suction force, and this suction flow is The open shutter is used as an air guide plate to allow the air to flow smoothly toward the vacuum cleaner without increasing intake noise, and the outside air that drives the turbine is selectively taken in from areas other than the bottom of the brush chamber. It is constructed so that the line type can be brushed without inhaling the cleaning liquid introduced through the hole and sprinkled on the paper type.

An embodiment of this invention will be described based on the drawings.

(1) is a main body, and this main body (1) is constructed by assembling an upper case (3) and a lower case (4) with a bumper (2) in between. If you remove the upper case (3) to see the inside, you will see that inside the main body (1) is a horizontally long brush chamber (5).
and a central ventilation passage (6) by a partition 111 (7) K, and a molded partition wall (8) is attached to the side of this partition. A rotary book (9) is attached to the brush chamber (5).
is rotatably housed, and a large horizontally elongated suction opening is formed on its bottom surface. A turbine (6) that transmits rotational force to the rotating brush (9) by belt α force is housed in the central ventilation passage (6). In addition, the central ventilation duct (
In 6), the rotary tube (to), which is the connection part that is connected to the dust collection part of the vacuum cleaner via an extension pipe, etc., is moved to the rear of the rotation axis of the turbine (6) and has a nine-turn axis. It is fitted so that it can rotate freely back and forth.

Next, a leak hole α◆ is formed in the central lower surface of the main body (1), and an outside air intake hole (
) is formed on the central upper surface of the main body (1). Also,
The belt α force of the main body (1) and the lower part of the belt on the opposite side are the first
As shown in the figure and FIG. 13(d), a side passage hole (2) is formed that communicates the brush chamber (5) with the outside, and this side passage hole (
2) is communicated with the central ventilation passage (6) via a pipe (b) which is a side ventilation passage. A square tube (to) is connected to one end of this pipe α force, and a shutter (to) is attached to the opening surface of the rectangular tube (to) by a hinge while being biased in the closing direction as shown in FIG. It is rotatably mounted. This shutter (to) has an arm deer, and this arm (c) has a pin (c) that protrudes from an arcuate hole (2) formed on the top surface of the square tube (2) centering on the hinge (e). It is set up.

Furthermore, the partition wall (8) K has a large diameter through hole (F) through which the suction airflow bypasses the turbine (B), and a small diameter through hole (E) facing the lower part of the turbine (6). Four are formed. The through hole - is larger than the through hole (C), and its position in the left and right direction coincides with the leak hole a→.

Therefore, the main body (1) has the partition wall (7) (8
) An air passage switching plate is provided which slides along the side.

This air passage switching plate (B) protrudes from the window (C) formed on the - side of the upper case (3) and moves inward from the end to the line type cleaning position (A), the jumper position (B), and the tatami cleaning position. It has a knob 4 which can be fixed at any position (position E→, edge clean position). This knob 4 is formed with a protruding piece (2) which is engaged with a pressing portion facing the pin (to) of the square tube α.

The knob handle is slidably seen from below the guide lip (30a) shown in FIG. 2 and the guide plate (not shown) K covering the upper surface of the pipe (b). Of course, the pipe α force may be formed into a rectangular shape and guided by its upper surface, and the air passage switching plate @ includes the leak hole α◆, the outside air inlet hole (to), and the through hole ( (c) and (2) are formed with a lip 6 that separates them from each other, and a communication path (6) that opens the leak hole a4 outward from the inner end and communicates with the through hole (to). ), a communication path (to) that communicates with the outside air intake hole (to) through hole HK, and a large diameter communication path (b) that communicates the brush chamber (5) with the through hole (c). A communication path (2) is formed below the communication path (B) to communicate the leak hole α→ with the communication hole (2). has been done.

In such a configuration, the mode of use for cleaning paper types will be explained with reference to FIGS. 3 and 4.

Align knob 4 of the air passage switching board (to) with the outermost line type cleaning position (a) K of the window (to). As a result, as shown in Fig. 3, the small diameter through hole (2) is removed from the air path switching plate (2) and opened, and the leak hole a◆ is located below the communication path (2) and is opened. . Therefore, the large through hole (-) as shown in Fig. 4 (6) is closed, but the suction air flow sucked in from the suction opening (A) as shown by the arrow in Fig. 4 (J) is passed through the small through hole. (2), the airflow is sped up and sped up by the turbine (
2) Drive. As a result, the rotating brush (9) is rotated to brush the line type. During cleaning, the main body (1) is frequently raised from the floor, and each time the main body (1) is raised from the floor, outside air is also sucked in from the leak hole α→ as shown by the arrow in Fig. 4 (a). ) rotation speed and rotation noise will be reduced.

Next, FIGS. 5 to 7 show usage patterns for jumping on the floor surface such as line types. Move knob 4 to jumper position (b)
When placed in the position, the air passage switching plate (b)
The communication path (to) is located directly below the outside air intake hole (2) in the upper part of the main body (1) and faces the through hole of the partition 11 (8).

Therefore, the outside air flows from the outside air intake hole (2) through the communication path (to) the through hole (as shown by the arrow in FIG. 1 (-)).
2) Flow 1. Drive the turbine (2). Brush room (
The ventilation hole (5) communicating with the central ventilation passage (6) is closed by the wind speed switching plate (b). Therefore, the jump (Jump) sprays cleaning liquid on the wire type and brushes it with a rotating brush (9), but since the outside air that drives the turbine (2) is taken in from the top of the main body (1), moisture is prevented from being sucked in, and the electric Protect your vacuum cleaner's electric blower.

Furthermore, when cleaning hard floors such as between tatami mats and wooden boards, the usage of the spatula is shown in Figures 8 to 10. When knob 4 is placed in the tatami cleaning position (/→), the air path is cleared as shown in Figures w and 9. The switching plate (b) closes the leak hole α◆, the outside air intake hole (to), and the through hole), but the communication path (b) faces the through hole - of the partition 11 (8). Therefore, as shown by the arrow in Figure 10 <=>, the suction opening (to) i of the brush chamber (5)
- central ventilation passage (6) through the communication passage (b) and the through hole -
Outside air is sucked into the The cross-sectional area of this suction path is large, and the flow bypasses the turbine (2), so the turbine (6) is not driven. In other words, when cleaning hard floors, the turtle does not need to drive the rotating brush (9). .

Furthermore, the knob (2) is positioned at the edge clean position, as shown in Figures 11 and 1, in which the main body (1) is run along the corner of the section to suck in dust from walls, etc. Then, the force of the protrusion provided on the knob (2) presses the bottle 4 of the shutter (2) located between the central passageway (6) and the shutter (2) is activated by a spring (not shown). It opens against the restoring force. On the other hand, the communication path (2) is the leak hole α◆
located directly above. Therefore, as shown by arrow K in Fig. 13(j), dust is absorbed through the bypass hole (which opens near the wall).
2), the flow rate is reduced and the dust is sucked into the central ventilation passage (6) with a strong dust suction force. Although this suction air volume is small, outside air is sucked into the central ventilation path (6) from the leak hole a Therefore, sufficient air volume is secured to cool the electric blower.

In addition, since the shutter (2) has a hinge (E) that is placed closer to the rotating brush (9), it smoothly guides the intake air toward the rotating pipe (towards) and can be used as a wind guide plate. It is.

In this usage pattern of EdgeClean, the side passage hole α→ is arranged on one side opposite to the belt α force, so that it is possible to prevent dust from concentrating on the constant rotation transmission member, and to It is possible to increase the dust suction power by bringing the side passage hole (2) closer to the wall. In addition, the rotation transmission member of the shaft of the turbine (2) is arranged on the negative side of the main body (1), and the pipe a and the air passage switching plate are arranged on the other side. , the weight balance between the left and right sides is good and it is possible to improve operability. Furthermore, by setting the edge clean to the innermost position of the four-stage switching, the inward movement of the protrusion OI opens the shutter (to), and the outward movement closes the shutter (2). The opening and closing mechanism is simple.

In this way, by simply sliding a single air path switching board (K), it can be used for four different purposes, including wire cleaning, wire cleaning, hard floor cleaning, and edge clean.

Since this invention is configured as described above, the amount of air blown to the turbine can be varied to selectively rotate the turbine together with the rotating brush depending on the type of floor surface, and the outside air intake hole can be opened to allow the turbine to rotate. The outside air that drives the brush can be taken in without passing through the brush room, which allows brushing the wire types without inhaling cleaning fluid.Furthermore, the shutters on the side ventilation channels can be opened to remove dust near the walls. At this time, since the hinges of the shutter are arranged in the front, the shutter guides the suction air from the side ventilation passage toward the vacuum cleaner while smoothly curving the suction air. It can be used as a board, and therefore, by sliding a single airflow switching board, it can be used for multiple purposes such as K to FL, brush cleaning, line cleaning, cleaning hard floors such as tatami mats, edge cleaning, etc. It has the following effects.
