Description

vacuum cleaner

The present invention relates to a vacuum cleaner, particularly a hand-held rechargeable vacuum cleaner, having a suction nozzle, a dust collecting chamber and a fan, wherein the suction nozzle is connected to the fan through a suction passage during operation of the vacuum cleaner in a suction mode. When the object to be sucked is delivered to the dust collecting chamber, and the vacuum cleaner is operated in the regeneration mode, it can be connected to the base station, so that the dust contained in the dust collecting chamber is transported to the base dust collection of the base station by the fan of the vacuum cleaner. Cavity.

Vacuum cleaners of the above type are disclosed in detail in the prior art. These vacuum cleaners have so-called permanent vacuum cleaners which, when fully filled with the object to be smoked - or when not fully filled as needed - are not replaced, but by purging the air flow in a direction opposite to the direction of the conventional suction direction The suction is removed. For this purpose, the dust collecting chamber of the vacuum cleaner is connected to the own fan of the vacuum cleaner by fluid deflection.

The publication EP 1 243 218 B1, for example, discloses a vacuum cleaner which can connect its dust collecting chamber to a base station for cleaning and/or emptying. The base station includes a basic dust collecting chamber, and the suction object can be transferred from the dust collecting chamber to the basic dust collecting chamber, wherein the suction airflow generated by the self-owned fan of the vacuum cleaner to be cleaned can be deflected to the dust collecting chamber through the basic dust collecting chamber. The object to be sucked can be sucked into the base dust collecting chamber from the dust collecting chamber by the negative pressure generated thereby in the basic dust collecting chamber.

In order to connect the vacuum cleaner fluid to the air path of the base station, two connections are required. The head is a connector for connecting the base station to the fan and a second connector for connecting the base station to the dust collecting chamber. The fan and the dust collecting chamber are usually located on opposite sections of the vacuum cleaner, so that the user of the vacuum cleaner must simultaneously align and connect the two joints to each other when the vacuum cleaner is connected to the base station. This is inconvenient and error-prone for the user.

In view of this, it is an object of the present invention to design the vacuum cleaner in such a manner that the user can conveniently connect the vacuum cleaner to the base station in a time-saving and accurate manner.

The solution to achieve the above object of the present invention is that the cleaner has a regeneration duct constructed independently of the suction passage and for fluidly connecting the fan to the dust collecting chamber, and corresponding to the regeneration duct and the suction a multi-channel interface of the channel, the interface having a first joint for connecting the base dirt collection chamber to the suction passage and a second joint for connecting the base dust collection chamber to the regeneration air passage.

Accordingly, the vacuum cleaner of the present invention has a multi-channel interface that provides a joint for connecting the regeneration air passage and the suction passage of the vacuum cleaner to the base station. Beneficially, the joints of the multi-channel interface are arranged next (i.e., in close proximity). Other air duct joints are available on this interface as needed. Therefore, by means of the interface, the end region of the regeneration duct, that is, the end region of the regeneration duct away from the fan, is guided to the position of the suction passage which is also away from the end region of the fan, so that the two end regions are substantially Side by side, so that only the base station needs to be directed to the interface with two end regions. Thus, the multi-channel interface is similar to a socket or plug and corresponds to a plug or socket of a base station.

Therefore, for the user of the vacuum cleaner, the connection of the vacuum cleaner to the base station is particularly simple and time-saving.

The present invention proposes that the multi-channel interface can be connected to the base station in such a manner that the dust collecting chamber is connected to the basic dust collecting chamber by the first joint and the fan is The second joint is coupled to the base dirt collection chamber. The first joint and the second joint of the interface are connected to the basic dust collecting chamber, so that the fluid connection between the dust collecting chamber and the vacuum cleaner fan can also be established through the basic dust collecting chamber. The air sucked by the fan from the dust collecting chamber is filtered inside the base dust collecting chamber of the base station, so that only the air that has been purged of the object to be sucked reaches the fan of the first vacuum cleaner. The objects to be sorbed (i.e., dirt, dust, and the like) remain in the air filter disposed in the base dust collection chamber and can be removed as needed.

According to the invention, the first joint has a discharge valve for discharging air from the dust collecting chamber, and the second joint has an inlet valve for allowing air to enter the regeneration duct. The discharge valve and the inlet valve are used to close the joint when the joint of the cleaner is not connected to the base station, such as during a pumping operation. In this regard, the objects to be absorbed collected by the dust collecting chamber of the vacuum cleaner do not escape into the surrounding environment.

The invention proposes that the discharge valve and/or the inlet valve can be opened by mechanical action of a corresponding connection zone of the base station and/or can be manually opened by a user, and/or can be used in the regeneration wind by the fan The negative pressure generated inside the track is opened. According to a first embodiment, the corresponding connection zone of the base station can act on the discharge valve and/or the inlet valve such that the valves open in the flow direction during operation of the vacuum cleaner in the regeneration mode. The corresponding connection zone of the base station can be, for example, a tappet that acts on the discharge valve and/or the spring-actuated check valve of the inlet valve. According to an alternative second embodiment, the user can manually open the discharge valve and/or the inlet valve. To this end, the user can, for example, actuate a switch that is connected to the valve, wherein the tappet or the like can again act on the check flap or the like of the valves. In this case, the user decides at the time when the valve is opened, because the opening operation is not automatically performed while the vacuum cleaner is connected to the base station. According to another embodiment, the discharge valve and/or the inlet valve can also be opened by a negative pressure generated by the fan inside the regeneration duct. Wherein, the valves are designed such that a base station is connected to the multi-channel interface In the case where the negative pressure inside the regeneration duct reaches a corresponding threshold, the valves are opened in conjunction with the suction of the fan of the cleaner. For example, the spring force acting on the check flaps of the valves can be designed such that the check flap opens only when a certain negative pressure is reached, thereby establishing a fluid connection between the fan of the cleaner and the dust collecting chamber.

According to the claimed invention, the suction passage between the fan and the dust collecting chamber has a secondary air valve. Therefore, when the dust collecting chamber is sucked by the fan, the secondary air can be guided to the dust collecting chamber to provide clean secondary air to clean the dust collecting chamber, in particular, to clean the permanent filter disposed in the dust collecting chamber. Device. The permanent filter can, for example, be cylindrical and have a cleaning element concentrically arranged inside thereof and substantially likewise cylindrical, the cleaning element having a cleaning nozzle, wherein clean secondary air flows into the cleaning element substantially axially, causing the cleaning element Rotation occurs, and the secondary air flows through the filter material of the permanent filter from the inside to the outside, thereby causing the object to be adsorbed attached to the outside of the filter material to fall off. The air containing the discharged material to be sucked flows into the basic dust collecting chamber through the discharge valve of the interface, where it is filtered by a basic air filter (for example, a common filter bag) and passes through the inlet valve of the two-channel interface to the vacuum cleaner via the regeneration air passage. A fan, where it is finally discharged to the surrounding environment.

The present invention provides that, in the case where a base station is connected to the interface, the secondary air valve can be opened by mechanical action of a corresponding partition of the base station, and/or the fan can be used in the regeneration air duct and the pumping The negative pressure generated inside the suction channel is opened and/or can be manually opened by the user.

Advantageously, the secondary air valve has a check valve or a similar valve element that disconnects the suction passage between the fan and the dust collecting chamber while the secondary air passage is opened, so that the fan and the dust collection are provided There is no direct flow path between the chambers, and the air can only reach the fan of the vacuum cleaner through the dual channel interface and the basic dust collection chamber disposed thereon.

According to the claimed invention, the suction passage between the dust collecting chamber and the suction nozzle has a chamber valve. When the chamber valve is closed, it prevents secondary air from entering the suction passage and adversely affects the regeneration mode. The chamber valve is further used to close the nozzle such that, for example, during operation of the vacuum cleaner or during operation in the regeneration mode, the object to be wicked in the dust collection chamber cannot be released from the nozzle to the surrounding environment.

During operation of the vacuum cleaner in the aspiration mode, the chamber valve may advantageously be opened by a negative pressure generated by the fan inside the suction passage and/or may be manually opened by a user. If the vacuum cleaner is not connected to the base station, the valve of the multi-channel interface is closed, so that air can only flow from the nozzle to the fan, so that the chamber valve is automatically opened when the fan generates a negative pressure inside the dust collecting chamber. For example, the opening time point can be adjusted by the elastically acting check valve of the chamber valve. Similarly, the user of the vacuum cleaner can also open the chamber valve manually (for example, by a switch), so the user can decide the opening time point at his own discretion.

Finally, as previously mentioned, the inlet valve and/or the outlet valve and/or the secondary air valve and/or the chamber valve may have a resiliently acting check valve.

In addition to the vacuum cleaner of the present invention, the present invention also provides a system comprising a base station and a vacuum cleaner, wherein the vacuum cleaner can be connected to the base station when operating in a regenerative mode, so that the dust collector of the vacuum cleaner is included by the fan of the vacuum cleaner The object to be sucked is delivered to the base dust collection chamber of the base station, wherein the vacuum cleaner is the vacuum cleaner of the present invention and the base station has a connection zone corresponding to the multi-channel interface of the vacuum cleaner. Thus, in general, the user can connect the vacuum cleaner to the base station through a single interface that provides a number of connectors. This enables the function of the plug and socket configuration.

1 is a perspective view of a vacuum cleaner; FIG. 2 is a cross section of the vacuum cleaner according to the first embodiment when operating in a suction mode; and FIG. 3 is a cross section of the vacuum cleaner of FIG. 2 connected to a base station and operating in a regeneration mode; 4 is a cross section of the cleaner according to the second embodiment when operating in a suction mode; and FIG. 5 is a cross section of the vacuum cleaner of FIG. 4 when connected to a base station and operating in a regeneration mode.

The vacuum cleaner 1 of Fig. 1 is constructed as a hand-held rechargeable vacuum cleaner. The vacuum cleaner has a suction nozzle 2 which moves on the floor to be cleaned when the vacuum cleaner 1 is operated in the suction mode, so that the object to be sucked can be sucked from the floor and passed through the suction nozzle 2 into the cleaner 1. The suction nozzle 2 is fluidly connected to the fan 4 of the vacuum cleaner 1, so that the fan 4 can suck in air through the suction nozzle 2 during the suction operation. The fan 4 corresponds to a fan exhaust port 22 through which filtered air can exit the vacuum cleaner 1. Furthermore, the vacuum cleaner 1 has a shank 23 for guiding the vacuum cleaner 1 during a suction operation.

Figure 2 is a cross-sectional view of the vacuum cleaner 1 of the present invention during a pumping operation. Next to it is a base station 6 which is also shown in cross section, which is not connected to the vacuum cleaner 1 when the vacuum cleaner 1 is operating in the suction mode.

The vacuum cleaner 1 has a suction passage 5 between the suction nozzle 2 and the fan 4, and a dust collecting chamber 3 having a cleaner air filter 17 is disposed in the suction passage. The vacuum cleaner air filter 17 has a cylindrically disposed filter material 18 and a cleaning element 19 which is likewise substantially cylindrical and coaxially disposed inside the filter material 18. Vacuum cleaner air filter 17 Corresponding to the sealing ring 20, the sealing ring can be switched to a different flow path through the vacuum cleaner air filter 17 for the suction mode or the regeneration mode.

Furthermore, the vacuum cleaner 1 has a multi-channel, here a two-channel interface 9, through which the vacuum cleaner 1 can be connected to the base station 6. The interface 9 comprises a first joint 10 having an inlet valve 13 and a second joint 11 having a discharge valve 12. The inlet valve 13 closes or opens the regeneration duct 8, which is constructed independently of the suction channel 5. The regeneration duct 8 leads from the second joint 11 to the fan 4 of the cleaner 1.

Furthermore, the suction channel 5 has a secondary air valve 15 between the fan 4 and the cleaner air filter 17, which secondary valve can be made twice during operation of the cleaner 1 in the regeneration mode (shown later in Figure 3) The air enters the dust collecting chamber 3, which is closed during operation of the vacuum cleaner 1 in the suction mode shown here, so that the fan 4 is directly connected to the dust collecting chamber 3 or the vacuum cleaner air filter 17 disposed therein . Furthermore, a chamber valve 16 is provided in the suction channel 5, which opens the nozzle 2 so that the object to be sucked can enter the dust collecting chamber 3 from the floor to be cleaned.

The base station 6 has a basic dust collecting chamber 7 having a basic air filter 21 comprising a filter material 18, here a conventional dust filter bag. In order to be connected to the interface 9 of the vacuum cleaner 1, the base station 6 has a connection zone 14 having a partition corresponding to the first connector 10 and the second connector 11 of the interface 9. The base air filter 21 has a filter connection plate 24 that is commonly used in filter bags, and the filter connection plate has a filter cover that can be operated by air pressure.

In the suction mode of Fig. 2, the fan 4 draws in air from the floor to be cleaned through the suction passage 5 and the suction nozzle 2. In this case, the object to be sucked passes through the suction nozzle 2 into the dust collecting chamber 3, where the sucked air must flow through the filter material 18 of the cleaner air filter 17 to reach the fan 4. The object to be absorbed contained in the inhaled air It is attached to the filter material 18 of the cleaner air filter 17, so that only the cleaned air can reach the fan 4. In this state, the seal ring 20 provided on the cleaner air filter 17 is lifted to the open position so that the air flows through the filter material 18 but does not flow through the cleaning member 19. The negative pressure generated by the fan 4 causes the seal ring 20 to separate from the cleaner air filter 17 to open the flow path through the filter material 18. During the pumping operation, the secondary air valve 15 is closed, so that the suction passage 5 from the suction nozzle 2 to the fan 4 is opened. The vacuum cleaner 1 can continue to operate in the suction mode until the filter material 18 of the vacuum cleaner air filter 17 is completely filled with the object to be sucked, so that the vacuum cleaner 1 no longer exerts a suction effect on the floor to be cleaned.

In order to ensure an effective pumping operation, it is necessary to regenerate the cleaner air filter 17, i.e., to remove the material to be adsorbed on the filter material 18. For this purpose, the regeneration mode shown in Fig. 3 is implemented, for which purpose the interface 9 of the vacuum cleaner 1 is connected to the corresponding connection zone 14 of the base station 6. The connection zone 14 of the base station 6 has a section corresponding to the discharge valve 12 of the interface 9 and the inlet valve 13, which here has tappets which cause the valves 12, 13 to open when the base station 6 is connected to the interface 9. In the illustrated embodiment, the lobes of the discharge valve 12 are deflected toward the base station 6, and the lobes of the inlet valve 13 are deflected to the regeneration tract 8 of the cleaner 1. In this regard, the valves 12, 13 are constructed such that the valves open in the direction of the regeneration mode. The regeneration duct 8 is opened through the open valves 12, 13 to draw in air from the base dust collecting chamber 7 of the base station 6 by the fan 4 of the cleaner 1. The secondary air valve 15 is opened due to the negative pressure inside the regeneration duct 8, so that the secondary air can enter the dust collecting chamber 3 and reach the basic dust collecting chamber 7. Wherein, the secondary air valve 15 simultaneously separates the suction passage 5, so that the fan 4 cannot take in air from the dust collecting chamber 3 on the direct flow path. Specifically, the air can only pass through the regeneration air passage 8 and the basic dust collecting chamber. 7 flows to the fan 4. At the same time, the suction acting on the chamber valve 16 in the suction mode is therefore no longer present, the chamber valve The 16 is kept closed so that the object to be absorbed contained in the dust collecting chamber 3 cannot be released to the surrounding environment through the chamber valve 16 and the suction nozzle 2.

The air entering the dust collecting chamber 3 of the cleaner 1 through the secondary air valve 15 flows through the cleaning member 19 provided inside the cleaner air filter 17. The flow path through the cleaning element 19 is defined by a sealing ring 20 placed on a corresponding section of the filter material 18. Therein, air flows through the cleaning element 19 which can be advantageously constructed as a rotary air nozzle. In this case, the inside of the filter material 18 is subjected to air to remove the object to be sucked on the outer side of the filter material 18, which flows with the air passing through the dust collecting chamber 3 toward the first joint 10 of the interface 9. The air carrying the object to be sucked passes through the open discharge valve 12 of the interface 9 of the cleaner 1 and the filter connection plate 24 of the base air filter 21 of the base station 6 into the base air filter 21 of the base station 6. Therein, the object to be sucked is intercepted by the filter material 18 of the base air filter 21 such that only the cleaned air flows to the inlet valve 13 of the interface 9 of the vacuum cleaner 1. The cleaned air exits the base station 6 via the inlet valve 13 and flows through the regeneration duct 8 to the fan 4 of the cleaner 1. Subsequently, the air can again exit the cleaner 1 via the fan vent 22 . The object to be sucked is in the base air filter 21 of the base station 6 and can be cleared by the user of the base station 6.

Once the vacuum cleaner 1 is again separated from the base station 6, the valves 12, 13 are closed so that the regeneration duct 8 is no longer flowing. When the fan 4 is in operation, air is sucked from the suction nozzle 2 only directly through the suction passage 5, wherein the air is filtered by the vacuum cleaner air filter 17 provided inside the dust collecting chamber 3.

4 and 5 show an alternative embodiment of the vacuum cleaner 1 of the present invention. The interface 9 for connecting the vacuum cleaner 1 to the base station 6 comprises a free end region of the nozzle 2 as a first joint 10 which is in contact with the substrate to be cleaned during operation of the vacuum cleaner 1 in the suction mode. The second joint 11 is disposed away from the vacuum cleaner 1 in the regeneration duct 8 On the end of the fan 4. Therefore, during operation of the vacuum cleaner 1 in the regeneration mode, the objects to be collected collected by the dust collection chamber 3 can be conveyed to the base dust collection chamber 7 of the base station 6 by the first joint 10 of the suction nozzle 2 (see the description of Fig. 5). The regeneration duct 8 corresponds to an inlet valve 13 which closes the regeneration duct 8 when the cleaner 1 is operating in the suction mode and is opened when the cleaner 1 is connected to the base station 6 to effect the regeneration mode. The first joint 10 of the suction nozzle 2 has a chamber valve 16 which is opened by the negative pressure generated by the fan 4 in the regeneration mode, for example, towards the base station 6, or by being disposed at the base station 6. The tappet turns the chamber valve into the nozzle 2.

While the cleaner 1 is operating in the regeneration mode shown in FIG. 5, the fan 4 of the cleaner 1 draws in air from the base dust collecting chamber 7 of the base station 6 through the regeneration duct 8. Thereby, dust-laden air is simultaneously supplied from the dust collecting chamber 3 to the base dust collecting chamber 7 of the base station 6, where the filter material 18 disposed in the base dust collecting chamber 7 by the base air filter 21 is used. The object to be aspirated is filtered off.

In the above-described illustrated embodiment, the valves such as the discharge valve 12, the inlet valve 13, the secondary air valve 15, and the chamber valve 16 are opened only by the negative pressure generated inside the cleaner 1, but may alternatively be used. The manual operation of the valves 12, 13, 15, 16 by means of a switch. Electronic switches can also be used as needed, which identify the docking of the vacuum cleaner 1 at the base station 6, thereby inducing manipulation of the valves 12, 13, 15, 16.
