Description

[Detailed Description of the Invention] The present invention relates to a carpet cleaning suction tool for a vacuum cleaner.

A conventional carpet cleaning suction tool for a vacuum cleaner will be explained based on FIG. 7. 101 is a main case, 102 is a cleaning liquid tank provided at the top of the main case 101, and 103 is a brush chamber provided at the front inside the main case 101, in which a rotating brush 104 is rotatably installed. It is arranged. 10
Reference numeral 5 denotes a turbine chamber provided in the rear part of the main case 101, in which a turbine chamber 106 is rotatably disposed. 107 is the turbine 10
6, a belt for transmitting the rotational force to the rotating brush 104; 108, a vacuum cleaner suction pipe; 109, a cleaning liquid supply device; 110, a spray nozzle; 111, a suction passage; 112, an on-off valve for the passage 111;
3 is an intake port.

In the above conventional configuration, when cleaning, the on-off valve 1
12 upward from the state shown in the figure to open the suction passage 111 and close the intake port 113 with a lid (not shown), and during cleaning, close the suction passage 111 with the on-off valve 112 as shown in the figure. At the same time, the intake port 113 is opened.

According to such a conventional device, since the suction passage 111 is simply closed by the on-off valve 112 during cleaning, the bubbles in the brush chamber 103 can leak into the gap between the on-off valve 112 and the main case 101. There is a disadvantage that it is easy to enter the turbine chamber 105 in a negative pressure state through the air.

Therefore, the present invention provides a carpet cleaning suction tool for a vacuum cleaner that eliminates such drawbacks.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 6. Reference numeral 1 denotes the main case, and 2 its upper cover, whose lower end opening edge is fitted into the upper end opening edge of the main case 1, and then screwed to the main case 1. At the lower front side of the main case 1, there is an elongated brush chamber 5.
A turbine chamber 6 is formed in the rear upper part.
10 is a rotary brush rotatably disposed in the brush chamber 5; 12 is a turbine rotatably disposed in the turbine chamber 6; 16 is a belt that transmits the rotational force of the turbine 12 to the rotary brush 10. , 7 is a spray nozzle extending from the turbine chamber 6 toward the brush chamber 6, and 11 is an air inlet extending from inside the brush chamber 5 toward the turbine chamber 6, and is opposed to the spray nozzle 7. 17 is a lid body disposed in an opening 18 formed at the upper front side of the upper lid 2,
It can freely move up and down using the hinge portion 17a as a fulcrum. Reference numeral 22 denotes a passage section which is disposed on the lower surface of the lid 17 so as to be movable in the directions of arrows A and B, and which is located between the spray nozzle 7 and the air inlet 11 when the lid 17 is closed. , a cleaning passage 1 is provided which communicates the spray nozzle 7 and the air inlet 11 with each other and guides air from the brush chamber 5 to the turbine chamber 6.
9 and the air inlet 2 of the spray nozzle 7 and the lid 17
A cleaning passage 21 is formed in which air is directly introduced into the turbine chamber 6 from the outside air.
35 is a sliding plate fixed to the passage section 22,
It has a long hole 36 along the directions of arrows A and B, and the lid body 17
The support 37 is brought into contact with a support 37 that protrudes from the support 37. 3
8 is a bolt whose threaded portion is screwed into a screw hole on the upper surface of the support column 37 through the elongated hole 36; 39 is a washer disposed between the head of the bolt 38 and the sliding plate 35;
Guide plates 40 and 41 are fixed to the lid 17 in the directions of arrows A and B, and guide the passage portion 22 in the directions of arrows A and B. 9 is a dust suction port formed on the lower surface of the brush chamber 5; 8 is a turbine chamber 6;
A suction pipe 42 of a vacuum cleaner is connected thereto.

The operation of the above configuration will be explained. First, the suction pipe 42 of the vacuum cleaner is connected to the pipe section 8. When cleaning the carpet next time, the lid 17 is opened, the passage section 22 is moved in the direction of arrow A, and the lid 17 is closed. Then, as shown in FIG. 2, the spray nozzle 7 and the air inlet 11 are brought into communication via the cleaning passage 19. When the vacuum cleaner is operated in such a state, the air in the brush chamber 5 is sucked into the turbine chamber 6 through the air inlet 11, the cleaning passage 19, and the spray nozzle 7, and collides with the wind contact part of the turbine 12. do. As a result, the turbine chamber 12 is rotated in the direction of arrow C, and the belt 1
The rotary brush 10 is also rotated in the direction of arrow D via the brush 6, and the brush 10 scrapes up dust attached to the carpet.

When cleaning the carpet next time, the lid 17 is opened, the passage section 22 is moved in the direction of arrow B, and the lid 17 is closed. Then, as shown in FIG. 3, the spray nozzle 7 communicates with the air inlet 20 via the cleaning passage 21. Next, after spraying the cleaning solution on the carpet, run the vacuum cleaner. Then, the outside air enters the air inlet 20 and the cleaning passage 2.
1 and the spray nozzle 7 into the turbine chamber 6, the turbine 12 is rotated in the direction of arrow C, and the rotary brush 10 is further rotated in the direction of arrow D via the belt 16. Sputum is washed. In this case, the air inlet 11 and the spray nozzle 7 are connected to the passage section 2.
2, the bubbles in the brush chamber 5 will not be sucked into the turbine chamber 6 via the spray nozzle 7.

As described above, according to the carpet cleaning suction tool for a vacuum cleaner of the present invention, simply by moving the passage, the spray nozzle can be moved into the brush chamber through the cleaning passage or the washing passage provided in the passage. Alternatively, it can be communicated with the outside air and is easy to operate. Further, the passage section is disposed between the spray nozzle and the air inlet, and can completely separate the spray nozzle and the air inlet during cleaning. Therefore, during this cleaning, the bubbles in the brush chamber are not sucked into the spray nozzle. It also prevents air leakage.
