Description

The present invention relates to an upright type vacuum cleaner.

[Prior Art] Although the history of vacuum cleaners has already been counted for decades, it has spread to most domestic households and is now one of the essential electric appliances for each household. As such, there are many types of vacuum cleaners, and their functions are becoming more sophisticated. However, there is no limit to the development of functions, and new functions are developed and provided daily by each manufacturer, and new products that are more convenient and usable are introduced and marketed.

Generally, the most popular general-purpose vacuum cleaners are a motor-driven fan for suctioning air, a main body that contains a paper pack that filters and stores garbage from the sucked air, and a floor that moves along with the air It is composed of a floor nozzle for sucking dust, and a hose connecting the floor nozzle and the main body.

FIG. 4 is a side view showing the general type vacuum cleaner, in which (1) is a vacuum cleaner main body, (2) is a floor brush, (3) is a hose, (4) is an operation unit, and (5) is It is a touch switch.
In using the vacuum cleaner, the user holds the operation unit (4) and operates the touch switch (5) to set the main unit (1).
The nozzle (2) at the tip of the hose (3) is moved to the floor surface while dragging on the floor surface, and dust on the floor surface is sucked together with air.

By the way, in contrast to the general type vacuum cleaner in which the main body (1) and the floor nozzle (2) are recently connected by a hose (3), an upright type electric cleaner in which the floor nozzle (2) is directly mounted on the main body (1). Machine is appearing. FIG. 5 is a side view showing the upright type vacuum cleaner, FIG. 6 is a perspective view showing use on a normal floor, and FIG. 7 is a side view showing use in a low place. (1) is a main body, (1a) is a grip portion, (2) is a floor nozzle, (6) is an annular handle, (7) is a wheel, (8) is a floor surface, and (9) is a main body (1). Arrow indicating the tilt direction, (1
0) is a vacuum cleaner user.

As shown in the figure, the main body (1) is engaged with the floor nozzle (2) by an articulated structure (not shown) so as to be tiltable in the direction of the arrow (9), and the dust and air sucked by the floor nozzle (2) are combined with the air. Is configured to be sucked into the suction port of the main body (1) via the short hose (3). The handle (6) is extendable in the axial direction.

In using the upright type vacuum cleaner, the user grips the handle (6) of the vacuum cleaner with one hand and adjusts the length thereof, and then starts the motor of the fan incorporated in the main body (1), By pressing the handle (6), dust on the floor (8) to be cleaned is sucked together with air and cleaned. Compared to the conventional general-purpose vacuum cleaner that holds the long hose (3) and drags the body (1) over the floor (8), the upright-type vacuum cleaner requires only one push to clean. Because it can be done, cleaning is much easier than a general vacuum cleaner.
In addition, the general-type vacuum cleaner removes the hose (3) from the main body (1) and stores it with the main body (1) when storing, while the upright type vacuum cleaner holds the hose (3) with the handle (6) hanging. Alternatively, since it can be stored by pushing, the handling is very convenient.

As described above, since the upright type vacuum cleaner has several advantages as compared with the general type vacuum cleaner, the upright type vacuum cleaner is generally popular, and demand for the vacuum cleaner is expected to increase.

[Problems to be Solved by the Invention] When performing cleaning using the upright type vacuum cleaner, for example, when cleaning the floor of a living room of a house, etc., as shown in FIG. With the main body (1) raised, the vacuum cleaner user (10) may hold the vacuum cleaner handle (6) and push it while standing, but as shown in FIG.
1) When cleaning low places, such as underneath, clean the main unit (1) almost in contact with the floor. One of the characteristics of the upright type vacuum cleaner is that the floor brush (2) can be cleaned by sticking it into a low place of the ceiling in this way. However, when the main body (1) is brought close to the floor surface (8) for cleaning in this manner, the weight of the main body (1) must be entirely suspended by the hand of the vacuum cleaner user (10) holding the handle (6). Therefore, if the low-height portion is cleaned for a long time, physical fatigue of the vacuum cleaner user (10) will increase. In order to avoid this fatigue, when the cleaner is moved by bringing the grip portion (1a) of the main body (1) into contact with the floor surface (8), the floor surface (8) may be damaged by the weight of the main body (1). is there.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems of the conventional upright type vacuum cleaner, and does not give a user of the vacuum cleaner a physical fatigue feeling and has no fear of damaging the floor surface. It is intended to provide a light-type vacuum cleaner.

Means for Solving the Problems In order to achieve the above object, an upright type vacuum cleaner according to the present invention is provided on a rear side of an annular handle extending above a main body including a fan and its motor. It is provided with wheels.

Further, the wheel may be formed of a soft material.

[Operation] The upright type vacuum cleaner according to the present invention is provided with wheels on the back side of the ring-shaped handle extending above the main body containing the fan and its motor and the like. By cleaning the lower part such as under a desk by lowering it to the vicinity and supporting the main body with the wheels, the weight of the main body is also applied to the wheels, so that the hand of the vacuum cleaner user holding the handle Since the weight of the main body does not take much, the movement of the main body can be performed smoothly without rattling, and furthermore, the handle can be prevented from being deformed or damaged without increasing the strength of the handle, and at this time, the wheels are attached to the floor surface The hand does not touch the floor, so that hand injury can be prevented.

Further, by forming the wheel with a soft material, it is possible to soften the collision with the floor surface when the handle extending above the main body falls to the rear side, thereby preventing the floor surface from being damaged.

[Embodiment of the invention] Fig. 1 is a side view of a vacuum cleaner showing an embodiment of the present invention, Fig. 2 is an enlarged view of a main part thereof, and (1) to (10) are conventional vacuum cleaners. The same or equivalent parts as (12) are wheels.

As shown in the figure, the gripping part (1a) on the back part of the main body (1)
Then, small wheels (12) are mounted on the shaft. The material of the wheels may be selected from materials that do not damage the floor (8), such as hard rubber and synthetic resin, according to the specifications of the floor to be cleaned.

When cleaning a low place such as under a desk (11), the main body (1) is brought close to the floor (8), and the main body (1) is supported by wheels (12). As a result, the vacuum cleaner is supported by the wheels (7) and the wheels (12). Next, the vacuum cleaner user starts the motor of the fan, grasps the ring-shaped handle (6), pushes the vacuum cleaner, rotates the wheels (7) and (12), and moves the wheel to the lower surface of the desk (11).

The lower part of 1) is cleaned.

During the cleaning of the lower part of the desk, since the weight of the vacuum cleaner is all supported by the wheels (7) and (12), a force is applied to the hand of the vacuum cleaner user (10) holding the annular handle (6). It doesn't feel physically tired even after long cleaning.

If the material of the wheel is appropriately selected according to the specification of the floor (8), for example, made of a soft material, the collision of the wheel (12) with the floor (8) is softened, and the wheel (12) is softened. It does not damage the floor (8).

In the present embodiment, the number of wheels is one, but the number is not limited to one, and a plurality of wheels may be coaxially arranged in parallel.

The diameter of the wheel may be small in the case of a plate floor, but in the case of a carpet floor, it is necessary to increase the diameter to some extent according to the length of the bristle feet of the carpet.

Further, the mounting position of the wheel (12) is not limited to the grip portion (1a) of the main body (1) of the present embodiment. The rear part of the main body (1), which is the position closest to the floor (8) when the main body (1) is brought close to the floor surface, and is a position suitable for supporting the weight of the main body. Is preferred. FIG. 3 shows another embodiment of the mounting position of the wheel, in which the wheel (12) is mounted on the current handle (6).

[Effects of the Invention] As described above, according to the upright type vacuum cleaner of the present invention, the wheels are provided on the back side of the ring-shaped handle extending above the main body including the fan and its motor. Therefore, by lowering the annular handle together with the main body to near the floor and supporting the main body by the wheels, the weight of the main body is also applied to the wheels when cleaning a low-height portion such as under a desk. Since the weight of the main body does not take much to the user's hand of the vacuum cleaner, the movement of the main body is performed smoothly without rattling, and furthermore, without increasing the strength of the handle, deformation and damage of the handle can be prevented, Also, at this time, the wheel comes into contact with the floor surface, and the hand does not come into contact with the floor surface, so that there is an effect that hand injury can be prevented.

Further, by forming the wheel with a soft material, there is an effect that the collision with the floor surface can be relieved when the handle extending above the main body falls to the rear side, and the floor surface can be prevented from being damaged.
