[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner, and more particularly, to a direction changing mechanism that can freely change the direction of a suction port of a cleaner body.

[0002]

[Prior Art]

 Generally, in this type of vacuum cleaner, as shown in FIG. 4, for example, a front wheel B and a rear wheel C are provided on the bottom of a cleaner main body A having a motor, a dust storage part, etc. inside, and The suction portion F is connected to the suction port on the front side via a bellows-like first hose D and a hard second hose E.

This electric vacuum cleaner is called a horizontal type, and is used as follows, for example. Immediately, first, when the switch (not shown) is closed, the motor built in the cleaner body A is driven, and the internal spaces of the first and second hoses D and E and the suction portion F are made negative pressure. To do. As a result, dust, dust, etc. at the portion where the suction portion F is located is sucked together with the air. Therefore, the floor surface is cleaned by operating the second hose E and sequentially changing the position of the suction portion F. Particularly, as the position of the suction part F is changed, the cleaner body A moves smoothly by the rotation of the front wheels B and the rear wheels C.

[Problems to be solved by the device]

 However, although this electric vacuum cleaner does not hinder the forward cleaning operation, if it is desired to reverse the cleaning area by 180 °, the cleaner main body A must be lifted by hand to reverse the direction by 180 °. .. Not only that, in the situation where the cleaning area needs to be changed frequently, it is necessary to manually change the direction of the cleaner main body A, which makes it difficult to perform the cleaning work efficiently.

Therefore, an object of the present invention is to provide an electric vacuum cleaner which can easily change the direction of the suction port of the cleaner body with a simple structure.

[0006]

[Means for Solving the Problems]

 Therefore, in order to achieve the above-mentioned object, the present invention has a cleaner body having a suction port on its peripheral surface, wheels disposed on both sides of the cleaner body, and detachably mounted on the suction port. The hose is equipped with a hose and has a diameter larger than that of a specific part of the cleaner body, and a suction part is attached to one end of the hose. It is composed.

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS.

In the figure, reference numeral 1 denotes a drum-like cleaner main body, in which, for example, a motor, a trash storage portion, etc. are arranged. A suction port 2 is formed on the peripheral surface 1a so as to communicate with the internal dust storage section. Wheels 3 and 3 having a diameter larger than that of the cleaner body 1 are rotatably disposed on both side surfaces 1b and 1b of the cleaner body 1 via shafts 4 and 4, respectively. The peripheral edges 3a of the wheels 3 are designed so as to protrude from the peripheral surface 1a of the cleaner body 1 over the entire circumference.

On the other hand, a first bellows-like hose 5 is connected to the suction port 2, and a hard second hose 6 and a suction part 7 are attached to the end of the first hose 5 so as to be sequentially removable. ing.

Next, the operation will be described. First, when a switch (not shown) is closed, the motor built in the cleaner body 1 is driven to make the internal spaces of the first and second hoses 5 and 6 and the suction portion 7 a negative pressure. As a result, dust, dust, etc. at the portion where the suction portion 7 is located is sucked together with the air. Therefore, the floor surface is cleaned by operating the second hose 6 and sequentially changing the position of the suction portion 7.

By pulling the second hose 6, the cleaner body 1 can easily move forward based on the rotation of the wheels 3 and 3 arranged on both side surfaces thereof to clean a desired floor surface area. It

Next, when it is desired to reverse the cleaning area by 180 °, the cleaner main body 1 is also centered around the shafts 4, 4 of the wheels 3, 3 by reversing the second hose 6 by 180 ° in the direction of the arrow in the figure. It can be rotated easily and the direction of the suction port 2 can be changed very easily. Therefore, it is not necessary to lift the cleaner body 1 by hand to change its direction.

FIG. 3 shows another embodiment of the present invention, in which the cleaner body 11 has a non-drum structure in which the portion having the suction port 2 protrudes from the wheel 3. The portion (specific portion) other than the vicinity where the suction port 2 is formed is set to be smaller than the outer diameter of the wheel 3. In this embodiment, when it is desired to invert the cleaning area by 180 °, the cleaner main body 11 also easily rotates around the shaft 4 of the wheel 3 by reversing the hose 5 in the direction of the arrow in the figure. The direction of the suction port 2 can be changed very easily.

[0014]

[Effect of the device]

 As described above, according to the present invention, the direction of the suction port to which the hose is connected can be easily changed according to the direction change of the hose because the diameter of the wheel is larger than the specific part of the cleaner body. It can be converted, eliminating the hassle of changing the direction of the vacuum cleaner body by hand.
