DETAILED DESCRIPTION of EXEMPLARY embodiments

Below is a detailed description of the node switch suction paths in accordance with an exemplary alternative implementation of the present invention with reference to the accompanying drawings.

In accordance with figures 1 and 2, the vacuum cleaner of the upright type according to approximate the option run this invention includes the main body 10, the housing 20 of the suction hole, the hose 30, the handle 40 of the control, an extension tube 50 and the node 100 switch suction paths.

The main body 10 includes a frame 11, a motor 13 to generate a suction force, the dust collector 15 and the separator 17 dust. The housing 20 of the suction holes of the hinge attached to the lower side frame 11 of the housing and the motor 13 is installed in the compartment 12 of the motor. Dust the node 14, which contains a dust collector 15 and the separator 17 dust, installed above the engine 13. The frame 11 of the housing contains the socket 11a, longitudinally located on its rear part, and the extension pipe 50 is inserted into this slot 11a. The hose 30 flow communicates with one side of the slot 11a, and in parallel with the socket 11a is made suction passage 11b.

The engine 13 is located in the compartment 12, which is made under the frame 11 of the housing. The engine 13 is a flow communicates with the separator 17, so that the air from which the separator 17 is separated dust is released to the outside through the exhaust hole 12A of the cover 12 of the engine.

The separator 17 separates dust from air drawn in through the suction force generated by the engine 13, and then separated dust accumulates in FilePlanet 15, located under the separator 17. The separator 17 may, preferably, be of a design of a cyclone, which separates dust from the air by centrifugal force is. However, such a decision should not be seen as restrictive, so as to collect dust instead of the cyclone can be used a dust bag (not shown).

The housing 20 has a suction inlet (not shown)located on its bottom surface and designed to pull in dust and air from the surface being cleaned through the first suction pipe 110 (see figure 2), and comprises a pair of moving wheels 21A and 21b located at the opposite rear sides of the housing 20 to facilitate movement on the surface. In this case, the pair of wheels 21A and 21b are attached rotatably to the housing 20.

The hose 30 is flexible along its length, one end of the flow communicates with one side of the arm 40, and the opposite end of the flow communicates with the suction passage 11b. The handle 40 includes a grip 41, whereby the user may grasp the handle. The grip 41 is held by the user, is located between the hose 30 and the tube 50 to provide between them a flow of messages.

Extension tube 50 has a predetermined length and is extracted from the slot 11a, while to the free end 51 (see figure 4) tube 50 attached auxiliary nozzle (not shown) so that the cleaner can work as a cleaner, container type to use is Itanium tube 50. When the tube 50 is not used, it is inserted into the slot 11a and attached to the frame 11 of the housing, while the intake system is changed so that the cleaner can operate as a vacuum cleaner of the upright type, which draws the dust and air through the housing 20. That is, when the tube 50 is inserted or removed from the slot 11a, the protrusion 141 is pressed or released, and depending on the work protrusion 141 tract suction of dust and air can be switched to the first suction path P1 (Fig 3) or the second suction path P2 (figure 4).

Tube 50 may have a telescopic structure so that its length can be adjusted, when the vacuum cleaner works like a vacuum cleaner, container type. Additionally, the tube 50 may be made up of a frame 11 of the housing, so that the user can easily move forward and back the body 20 of the suction holes in the cleaning mode, the vacuum cleaner of the upright type.

Next, with reference to figure 2-4 describes the node 100 switch suction paths in accordance with an exemplary alternative implementation of the invention. The node 100 includes the first suction pipe 110, the second suction pipe 120, the guide tube 130 and a pass-through tube 140.

One side of the first suction pipe 110 flow communicates with the housing 20, and the opposite side is bent for insertion into the chamber 101 switching paths. With this arrangement, each is of the opposite sides of the first suction pipe 110 and the second suction pipe 120 is held vertically and parallel to each other. Thus, when moving a bill of pipe 140 upwards, as shown in figure 4, it is flowing is communicated with the second suction pipe 120, forming a second suction path P2. In contrast, when moving a bill down the pipe 140, as shown in figure 3, it is flowing communicates with the first suction pipe 110, forming a first suction path P1. Accordingly, the ends of the opposite sides of the first and second pipes 110, 120 can be located on the same normal line. In this case, the camera 101 from the outside can be protected by a cover 103 from the blow.

One end of the guide tube 130 flow communicates with the separator 17 dust and is vertically parallel to one side of the slot 11a. In addition, the pipe 130 directs dust and air are entrapped from the conversion of the pipe 140, the separator 17.

One side of the conversion tube 140 is inserted slidable in the guide tube 130, and the opposite side is curved and extends a distance sufficient to selectively entering into contact with the opposite side of the first pipe 110 or from the opposite side of the second pipe 120. The push projection 141 inserted into the slot 11a made for one whole on the outer periphery of the pipe 140, and the return spring 144 mounted in the chamber 101, is located under the pipe 140 and supports due to the elastic force about avaprono side of the pipe 140 in the upper direction. The lower end of the spring 144 is fixed protrusion 105, located inside the chamber 101, and the upper end is fixed in a predetermined position on the lower outer periphery of the pipe 140.

With this arrangement, when the tube 50 is inserted into the slot 11a, as shown in figure 3, the transfer pipe 140 flow communicates with the first suction pipe 110 during movement of the slide down along the guide tube 130, as the push projection 141 is pressed by the tube 50. Alternative when removing the tube 50 from the slot 11a, as shown in figure 4, the pipe 140 flow is communicated with the second suction pipe 120, while the protrusion 141, which was pressed by the tube 50, moves sliding up under the action of the return spring 144.

From the lower end of the conversion tube 140 passes the partition 143. As shown in figure 4, when the transfer pipe 140 flow is communicated with the second pipe 120, the partition 143 closes the first pipe 110, so that you can advance to prevent the admission of dust into the chamber 101.

Next, with reference to figure 3 and 4, describes the method for switching between the first and second paths P1 and P2 of the vacuum cleaner of the upright type, in accordance with an exemplary variant of execution.

As shown in figure 3, to pull in dust and air from a cleaning surface through the housing 20 to the suction holes of the extension pipe 50 is inserted into the socket AV this case, as the push projection 141 is pressed down, the free end 51 of the tube 50, the transfer pipe 140, made in one piece with the guide 141 moves down, compressing the spring 144, so that the tube 140 may be flow connected to the first suction pipe 110 with the formation of the first suction path P1.

If in this state to start the engine 13, the dust and the air will be drawn into the housing 20 through its suction hole (not shown)in contact with the surface being cleaned, and then held in a pass-through tube 140 through the first suction pipe 110. Dust and air passing through the tube 140, is then passed to the separator 17 through the pipe 130, and then under the influence of centrifugal force, the dust is separated from air and accumulates in FilePlanet 15 under its own weight. The air separated from the dust that is released to the outside through the exhaust hole (not shown) of the separator 17, a flow communication with the engine 13, and then through the engine 13.

On the other hand, to perform work using tube 50 in the cleaning mode in the form of a vacuum cleaner, container type tube 50 is extracted from the slot 11a, as shown in figure 4. Accordingly, the push projection 141, which was pressed by the tube 50, is released and, thus, the transfer tube 140 moves upwards under the action of the elastic force of the spring 144.

In this condition the transfer pipe 140 flow not reported with the first pipe 110, and with the second pipe 120, so that the suction path can be switched from the first path P1 to the second path P2, and the partition 143 closes the first suction pipe 110.

In this mode, if the free end is extracted from the slot 11a of the tube 50 to install the appropriate auxiliary nozzle (not shown) and to operate the motor 13, the dust and the air flow into the suction passage 11b after passing sequentially through the auxiliary nozzle, the tube 50, the handle 40 of the control and the hose 30.

Dust and air entrapped in the intake passage 11b enter the pass-through pipe 140 through the second pipe 120, and then to the separator 17 through the guide tube 130. Dust, Tenuta in the separator 17, is separated from the air by centrifugal force and collected in FilePlanet 15 under its own weight, the air from which the separated dust is released to the outside through the exhaust hole (not shown) of the separator 17, a flow communication with the engine 13, and then through the engine 13.

As described above, in accordance with an exemplary alternative implementation of the invention, the intake system can be switched using the guide tube 130 and the conversion of the pipe 140, which may be selectively provide flow communication with the first pipe 110 and the second pipe 120, and not by a close or open the additional cavity. Thus, it is possible to prevent excessive pressure losses in the suction path when it is switching.

In accordance with exemplary embodiments of carrying out the invention the intake tract can be transferred simply by the introduction of the extension tube into the socket body frame or removing it from him. In addition, the transfer tube attached to the guide tube can be moved directly with software running messages from the first or second suction pipe, so that it is possible to reduce excessive pressure loss resulting from the switching of the intake tract.
