Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a floor suction tool used in a vacuum cleaner.

Main) Prior art As a technology prior to the present invention, for example, Utility Model Application No. 57-14
Publication No. 5554 discloses a floor suction device in which a plurality of concave ventilation passages connected to a horizontally elongated suction port are formed on the front surface, and a sliding plate that changes the cross-sectional area of the ventilation passages is operated by a manual operation lever. It is shown.

According to this conventional technology, even large dust particles on the cleaning floor can be sucked in by switching the manual operation lever, but there is a drawback that the suction performance deteriorates. It has the disadvantage of poor operability since it requires manual operation.

f→ Problems to be Solved by the Invention The technical problem of the present invention is to obtain a suction system for nine beds with a simple configuration that can suck even large amounts of dust without deteriorating suction performance and operability. .

B) Means for Solving the Problems In order to solve the above problems, the floor space of the present invention is freely pivoted, and a rotary plate body that rotates in conjunction with the wheels is pivoted within the front opening. It is characterized by nine things.

(E) Effect According to the above structure, as the floor suction tool moves, the wheels rotate on the floor surface to be cleaned, and in conjunction with the wheels, the rotary plate rotates within the front opening and closes the front opening. Open and close, and set the opening height to the floor surface to be cleaned by IJR. The rotary plate body is connected to the front opening rotor t-
When opened, the opening height with respect to the cleaning floor surface becomes higher,
The horizontally elongated suction port and the alligator manure front opening make it easier for suction air to flow into the floor suction tool, and large dust particles are sucked in from the front opening. On the other hand, when the rotary plate body closes the front opening, the height of the opening with respect to the cleaning floor is low;
Although the suction air flow rate from the horizontally elongated suction port is reduced, the X air space is not high, and the deep suction force is increased to reliably suck in dust even if the floor surface to be cleaned is a carpeted floor surface or a carpeted floor surface. In this way, the suction airflow is in a state where it can suck in large amounts of dust and a state where the degree of vacuum is high.
1 and 1 are alternately repeated by the rotation of the wheels, and the floor suction tool moves smoothly on the cleaning floor without deteriorating the suction performance and while sucking even large dust particles.

The front opening (151) is formed by removing the front wall portion of the air passage groove Uα located at the air passage groove Uα, and the front opening (151) communicates with the horizontally elongated suction port (9).

α Separate e is a pair of left and right front wheels, and these front single transport four housings e are respectively fixed to both sides of one shaft support shaft (17) with shafts M fixed to the pair of front wheel fitting recesses (141t141). It is rotatably supported by a shaft inside.

(181 is a rotary plate body which is fixed to the central part of the pivot shaft 1D and rotatably mounted in the front opening a9, and the rotary plate body t181 is connected to the pivot shaft 111C171
The straightening direction is the length head in the major axis direction and the thickness in the minor axis direction (
It is composed of an elongated plate body having an elliptical cross-section, which has a circular cross-section (a), and whose lateral width (to) in the axial direction of the support shaft (171) is slightly smaller than the width (2) of the front opening αS. The length and direction of the rotary plate body 11 seconds are the same as the cleaning floor surface (
When the front opening S is in an inverted state parallel to 19 (see Fig. 5 0), the front opening S is opened, while its length and direction are parallel to the floor surface to be cleaned (11). When it becomes vertical and stands up (see Figure 5 fp),
The front opening α9 is closed by the rotary plate body (L81), and the rotation of the front wheel al19ue is transmitted to the rotary plate side via the pivot shaft αD, thereby causing the rotary plate body to rotate. The rotary plate body (181) rotates and is configured to open and close the front opening αS to adjust the opening height with respect to the cleaning floor surface fi9. , which are formed on the left and right sides of the movable cylinder (6) mounting portion at the rear of the lower surface of the lower case (4), and are rotatably mounted on a pair of rear wheel fitting recesses.

The prisoner is a synthetic rubber suction keeper, and the lower case (

With the above configuration, when the suction hose of the vacuum cleaner is bent and the connecting pipe (71 connected to the floor suction tool) is moved forward on the floor surface L9 to be cleaned during cleaning, the front wheel 1flil
([9 rotates, and in conjunction with this rotation, the rotating plate body rotates within the front opening Oj. Then, the rotating plate body tt81 is inverted parallel to the cleaning floor surface α9, and the rotating plate body (15) When opened, the opening height from the cleaning floor WJ[ll is high, and the opening area is larger by the front opening 051 in addition to the horizontally long suction port (9), and the opening area is increased from the horizontally long suction port (9) and the front opening αS. A large amount of suction airflow flows into the floor suction A (11), and a large dust surface is sucked into the floor suction tool (11) from the front opening a5. The rotary plate body α is vertically erected.
) when the front opening Oj is closed, the height of the opening from the cleaning floor surface J becomes lower, and although the suction airflow t from the horizontally elongated suction port I91 decreases, the degree of vacuum increases and the deep suction force increases. To surely suck in dust even if the cleaning floor surface 9 is a carpet floor surface or a carpet floor surface. At this time, the large dust surface cannot be sucked in because it is obstructed by the rotary plate a, and the state in which the suction airflow can easily flow in and the large dust surface can be sucked in, and the state with a high degree of vacuum, are the conditions in which the front desk is moved. The rotation of f3 (161) is repeated alternately, and since the front wheel σ61 [161 is circular, it rotates smoothly, and therefore, the suction A for dirty floors smoothly without deteriorating the suction performance and sucking in large dust.
