Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for inserting and connecting a hose connected to an upper lid that covers a dust collection chamber from above so that it can freely rotate about the normal line to the connection surface as the axis of rotation. The invention relates to vacuum cleaners.

BACKGROUND OF THE INVENTION In a conventional vacuum cleaner 1 of this type, a hose connection portion is provided on the top surface of the upper lid 2, which is formed approximately parallel to the floor surface, as shown in FIG. 4, and a hose 3 is connected to the hose connection portion. . The hose connection part is formed so that the connected hose 3 can freely rotate about a normal line 4 at the connection part to the upper lid 2.

Problems to be Solved by the Invention However, as shown in Fig. 6, when the main unit is used in an upright position to clean ceilings and shelves, the hose is accidentally pulled too much, causing the main unit to fall in the direction in which the top cover 2 touches the ground. If it falls over, the hose connection pipe 5 will collide with the floor and be damaged.

Also, if you try to store the hose connection pipe 5 with it connected to the top lid 2, the storage location will be determined by the total height when the hose connection pipe 5 is connected, and you can't stand the main body in a narrower space. Another problem was that it could not be installed.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is that the hose connection part that rotatably holds the hose is inclined at an angle of about 30 to 60 degrees with respect to the floor surface. It is disposed on the top surface of the upper lid and is formed so that the maximum height from the floor to the hose connection tube when the hose connection tube is connected is not greater than the maximum height of the main body alone.

action This effect is as follows.

A hose connection device that rotatably holds the hose is installed inside the top surface of the top cover that is inclined at approximately 30 to 60 degrees with respect to the floor surface, and by connecting the hose here, the hose connection pipe can be connected from the floor surface. Lower the maximum height of the main body. As a result, even if you accidentally pull the hose too much when using the main unit upright, the hose connection pipe will not collide with the floor, so it is safe to avoid damaging the hose or hose connection pipe. It can be used for a long time with care.

Example An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, 11 is a main body case of a vacuum cleaner that houses an electric blower 12, and is divided into two parts, front and back, and the rear side includes the electric blower 12, a cord winding device (not shown), etc. The front side is a dust collection chamber that houses a filter unit 14 for collecting and accumulating dust sucked in through a hose 13, an extension pipe, and a floor suction port (not shown). There is. A pair of rear wheels 16 are attached to both sides of the rear end of the main body case 11, and a front wheel 16 is attached to the back of the bottom of the dust collection chamber to facilitate movement of the cleaning section during use.

Reference numeral 17 denotes a hose connection pipe, which is inserted into and connected to the top lid 18 that covers the dust collection chamber from above so as to be openable and closable, and rotates freely on the surface of the top lid 18. As a result, the hose 13 can freely rotate relative to the cleaner body.

In addition, the hose connection surface 19 of the upper lid 18 is
It is formed at an angle of 30 to 60 degrees, and when the hose connection pipe 17 is connected, the maximum height H from the floor to the hose connection pipe is
, are configured so that H1≦H2 as compared to the maximum height H2 of the vacuum cleaner body.

Next, the operation of this configuration will be explained.

The connection of the hose connection pipe 17 to the top lid 18 is made to a hose connection surface 19 of the top lid 18 . Since the hose 13 is rotatable on the hose connection surface 19 with the normal line 19 as the center axis, it can be used in an upright position to clean ceilings, shelves, etc., as shown in Figure 3. Even if the main body of the vacuum cleaner falls down by pulling the hose too much by mistake, only the parts of the vacuum cleaner main body such as the top cover 18 will collide with the floor, but the hose 13 and the hose connection pipe 1 will not be hit, so there will be no damage.

Furthermore, since the relationship H1≦H2 is shown in Figure 3, the hose 13 can be stored upright with the hose 13 connected to the vacuum cleaner body even in narrow spaces, so the next time the vacuum cleaner is used, it can be used immediately. Since the vacuum cleaner can be placed in a smaller space than conventional vacuum cleaners, it is possible to select a storage location for the vacuum cleaner body more advantageously.

Effects of the Invention The present invention provides a hose connection pipe that is rotatably connected to an upper lid that covers a dust collection chamber, and the maximum height of the hose connection pipe from the floor in a connector state to the maximum height of the vacuum cleaner body. By lowering the height, it prevents damage to the hose and hose connection pipe when the unit falls over, and it also improves usability and durability by allowing storage with the port connected in a narrower space than before. It can provide vacuum cleaners.
