One end of the connecting means is fixed in the center of the lower part of the upper casing and the other end has a shaft connected to rotate with the center of the upper part of the lower hull. In addition, the vacuum cleaner includes a cleaning station, an extension tube and a connecting tube for connecting the main building with a cleaning station. In the lower part of the upper body mounted wheels.

The drawback to this vacuum cleaner is that when turning the upper housing on the lower, wheels, moving along a curved trajectory, can become distorted and salinewaterbody with cleaner, to reduce the cleaning effectiveness and lead to rapid wear and breakage of the hose.

The objective of the invention is to provide a vacuum cleaner that does not have this drawback, i.e., reliable and effective and more comfortable to use.

This task is solved in that a vacuum cleaner that contains a main building, including the upper body, which creates a vacuum to collect dust and dirt, the lower housing is installed on the upper body can be rotated, and connecting means for connecting the upper housing to the lower housing with the possibility of rotation of the upper housing on the lower housing, with one end connecting means fixed in the center of the lower part of the upper casing and the other end has a shaft connected to rotate with the center of the upper part of the lower housing, and containing a cleaning attachment, an extension tube and a connecting tube for connecting the main building with a cleaning attachment according to the invention contains a bearing installed between the bottom of the upper housing and the upper part of the lower housing to reduce the friction between them and including grooves formed on the upper surface of the lower housing's contact with the lower part of the upper shell, while specified shaft provided with a lock that prevents the output shaft from the hole for the shaft and including a protrusion extending outward parallel to the longitudinal axis of the lower housing, and a spring for elastic displacement of the ledge.

In the proposed vacuum cleaner when the rotation of the upper housing on the lower balls will move freely in the groove, because they can turn around any spatial axis, so that the specified rotation will not be accompanied by spurts and increased stress on the connecting hose. Due to this, we offer a cleaner, more reliable and more convenient to use, and provides more effective cleaning.

The invention is illustrated by drawings, where Fig.1 shows in perspective the main body of the vacuum cleaner according to the present invention with a spatial separation of the parts; Fig.2 presents a side view of the main body of the vacuum cleaner according to the present invention; Fig.3 shows in perspective the construction of the known vacuum cleaner.

Known vacuum cleaner is used for cleaning floors and floor coverings by the retracting of them dirt along with air. This is done using a vacuum that is created as the difference between the pressure inside the GLA is and. It contains the main body 10, provided with a drive (not shown) and a means of collecting dust (not shown), the cleaning attachment 30, through which the dirt and dust drawn in from the surface being cleaned due to the vacuum created in the main body 10, an extension tube 20 and the connecting hose 22, which connects the cleaning attachment 30 to the main body 10. The ends of the connecting hose 22 connected respectively with the main body 10 and one end of the coupling 21 having a handle 23. The other end of the coupling 21 is connected to the extension tube 20, which is connected to the cleaning station 30, so that the extension tube 20 may be provided with connecting hose 22. Position 24 is designated the control.

The vacuum in the main body 10 is created by using a motor (not shown) and drive and contains the dust bag, which serves as a means of collecting dust (not shown). In addition, the lower part of the main body 10 is installed in the front and rear wheels 11 and 12 to facilitate its movement.

Connection sleeve 21 and the connecting hose 22 made of elastic materials, form a channel through which dirt and dust are sucked into the main body of the vacuum cleaner. Sistema istawa STB 30, on which the dust from the surface being cleaned together with the air sucked into the main body 10. Position 33 marked the movie, which facilitates the movement of the cleaning attachment 30.

When the user element 24 includes a vacuum motor (not shown) located in the main body 10 begins to operate and creates a vacuum. Thus, when the air at high speed is sucked into the main body 10 sequentially through the cleaning attachment 30, an extension tube 20, the connecting sleeve 21 and the connecting hose 22, the dust and dirt from the surface being cleaned through the suction hole 31 and the suction channel 32 are absorbed into the dust bag (not shown) of the main body 10. That is dirt using a vacuum created in the main body 10, is pulled through the cleaning attachment 30, passes through an extension tube 20 and the connecting hose 22 and is collected in the main body 10.

When the user cleans the floors and floor coverings with this known vacuum cleaner, he has to move the cleaning attachment 30 over a large area. Therefore, the main body 10 is also moved across the floor. Although the front and rear wheels 11 and 12 provide movement of wiredog and left turns of the main body 10. When turning the end of the connecting hose 22 connected to the main body 10, the applied torque force that causes the breakage of the connecting hose 22. These factors cause inconvenience to the user and reduce the efficiency of cleaning with a vacuum cleaner.

According to the present invention, a vacuum cleaner, as shown in Fig. 1 and 2, includes a main body 100, which serves to create a vacuum to collect the entrained dust and dirt. The main body 100 includes an upper housing 110 and lower housing 120.

The upper housing contains a drive (not shown), which creates a vacuum, and means for collecting dust (not shown), which collects entrapped dust and dirt. Connecting hose 220, through which the dust is drawn into the main body 100, is connected to the top housing 110. This connection hose through the extension tube (not shown) and the coupling (not shown) is connected with a cleaning device (not shown). In the lower part of the lower housing 120 is installed in the front and rear wheels 121 and 122, to facilitate the movement of the main building.

The upper housing 110, which is the distinguishing feature of the present invention, is connected with the lower housing 120 can be rotated with pousti the upper housing 110 is a shaft 130, fastened with fastening means, and in the center of the lower housing 120, which serves as a support for the upper body 110, there is a hole 131 to the shaft, is made so that the lower end of the shaft 130 is securely in him. At the lower end of the shaft 130 includes a latch 150, preventing the output shaft 130 of the holes 131. The latch 150 has a ledge 151, which is output in parallel to the longitudinal axis of the lower housing 120, and a spring (not shown), which elastically affects the ledge 151.

When the shaft 130 is inserted into the hole 131 to the shaft, the protrusion 151 retracts inside the shaft 130. However, once the shaft 130 is fully inserted into the opening 131, the protrusion 151 is returned to the extended position and thereby prevents the output shaft 130 of the holes 131.

To reduce friction between the upper housing 110 and lower housing 120 between them has a bearing 140, which allows the upper case 110 is smoothly rotated. The bearing 140 is formed with multiple grooves 142 located at a specified distance from the hole 121 to the shaft, and lots of balls 141, placed in the grooves 142. The upper housing 110 is connected to the lower housing 120 can be rotated around the shaft 130 and the upper body 110 rests on the balls 141. Balls 1E friction and load on the shaft 130. The following describes the operation of the main body 100 of the vacuum cleaner according to the invention.

The user, when cleaning floors, pulls on itself and pushes themselves from the main body 100 of the vacuum cleaner, smooth movement which provide front and rear wheels 121 and 122. This, and the fact that the upper body 110 is connected to the lower housing 120 can be rotated 360oaround the shaft 130 (which allows you to drastically change the direction of movement of the upper housing 110), enables the main body to move easily in any direction, which increases the efficiency of the vacuum cleaner.

In addition, the free rotation of the upper housing 110 prevents the flow of the load to the base of the tube 220.

As described above, the vacuum cleaner according to the present invention has a main building, which is divided into upper and lower housing, the upper housing connected to the bottom can be rotated around the shaft inserted into the bottom case. This design allows to change the direction of movement of the upper body for easy cleaning and prevents breakage of the connecting hose.
