Description

Base station for vacuum cleaner

The invention relates to a base station for cleaning and/or emptying a dust collecting chamber of a first vacuum cleaner, the base station has a basic dust collecting chamber, a first air inlet fluidly connected to the basic dust collecting chamber, and the base The dust collection chamber is a fluidly connected first air outlet, wherein the air inlet and the air outlet can be fluidly connected to the air duct of the first vacuum cleaner, so that the dust contained in the dust collection chamber of the first vacuum cleaner can be used by the first vacuum cleaner The fan is delivered to the basic dust collection chamber.

The aforementioned types of base stations have been disclosed in detail in the prior art. These base stations are especially used in combination with vacuum cleaners with so-called permanent filters, which are not replaced when they are completely filled with dust, but are cleaned of dust in the direction opposite to the conventional suction direction by the purge air flow . For this purpose, the dust collecting chamber of the vacuum cleaner is connected to the fan of the base station, or to the fan of the vacuum cleaner itself through fluid deflection.

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

Although this type of base station has good performance, it is only suitable for cleaning a single vacuum cleaner. In addition, only the fan of the vacuum cleaner is limited for cleaning.

In view of this, the object of the present invention is to provide a base station that can be connected to several vacuum cleaners simultaneously. Beneficially, these vacuum cleaners should be able to supplement and assist in cleaning another vacuum cleaner.

The solution of the present invention to achieve the above object is that the base station has a second air inlet that can be fluidly connected to the basic dust collection chamber, and a second air outlet that can be fluidly connected to the basic dust collection chamber, wherein the second The air inlet and the second air outlet can be in fluid connection with the air duct of the second vacuum cleaner, so that the dust contained in the dust collection chamber of the second vacuum cleaner can be transported to the basic dust collection chamber by the fan of the first vacuum cleaner.

Therefore, a passive base station, that is, a base station without its own fan, is proposed, which can be used to clean and/or empty several dust collecting chambers of vacuum cleaners simultaneously connected to the base station. For this purpose, the base station provides air inlets and air outlets for several vacuum cleaners, for example, the first air inlet and the first air outlet for the first vacuum cleaner, the second air inlet and the second air outlet for the second vacuum cleaner Exhaust and so on. In principle, the number of such air inlets and air outlets is not limited. Among them, the fluid connection between the basic dust collection chamber and the dust collection chambers of the vacuum cleaners can be operated in such a way that, for example, when the first and second vacuum cleaners are connected, if the fan of the first vacuum cleaner is not used to clean the first The dust collecting chamber of the vacuum cleaner cleans the dust collecting chamber of the second vacuum cleaner with the fan of the first vacuum cleaner. In principle, the dust collecting chamber of the second vacuum cleaner or another vacuum cleaner can of course be cleaned by its own fan.

In order to clean the dust chamber of the first vacuum cleaner by its own fan, establish a fluid connection between the first vacuum cleaner and the base station, so that the fan of the first vacuum cleaner passes through the first exhaust port to the base dust collection chamber of the base station Air is sucked. Among them, the air in the dust collecting chamber of the first vacuum cleaner flows into the basic dust collecting chamber through the first air inlet. for In order to form a closed flow circuit, the dust collecting chamber is again connected to the fan of the first vacuum cleaner. The dust contained in the dust collecting chamber of the first vacuum cleaner enters the basic dust collecting chamber through the fluid connection formed in the above manner, and is filtered out through the filter bag or similar components arranged in the basic dust collecting chamber, so that the flow direction The fan's air contains no dust. The basic dust collection chamber may-for example, when the filter is filled with dust-the base station is removed from this, and emptied or cleaned. Therefore, the vacuum cleaner as a whole does not need to have a detachable filter. To be precise, the air filter of the vacuum cleaner can be constructed as a permanent filter.

The invention proposes that the first air inlet and the second air inlet are correspondingly provided with a valve, which is suitable for selectively connecting the basic dust collection chamber with the dust collection chamber of the first vacuum cleaner or the dust collection chamber of the second vacuum cleaner. Therefore, through the valve, the fluid connection required for cleaning/emptying the first or second dust collecting chamber can be established. For this reason, the valve is arranged in an intermediate position, that is, it is arranged between the first air inlet and the second air inlet of this base station from the perspective of fluid technology. The valve is advantageously constructed as a tongue valve, wherein in principle, the valve can also adopt other structural forms. The valve selectively establishes a connection between the basic dust collection chamber and the first air inlet, or between the basic dust collection chamber and the second air inlet. If, for example, only the first vacuum cleaner is connected to this base station, the valve is maintained at a position where the first air inlet is connected to the basic dust collection chamber and the second air inlet is separated from the basic dust collection chamber, so that the basic dust collection chamber It is only connected to the dust chamber of the first vacuum cleaner.

The present invention proposes that the first exhaust port and the second exhaust port are also correspondingly provided with a valve, which is suitable for selectively connecting the fan of the first vacuum cleaner to the dust collection chamber of the first vacuum cleaner or the dust collection chamber of the second vacuum cleaner. According to this technical solution, the valve can be operated in such a way that the dust collecting chamber of the first vacuum cleaner or the second vacuum cleaner is cleaned by the fan of the first vacuum cleaner. When the dust collecting chamber of the second vacuum cleaner needs to be cleaned, for example, the valve arranged between the first air outlet and the second air outlet is operated so that the dust collecting chamber of the second vacuum cleaner It is in fluid connection with the fan of the first vacuum cleaner. The fan of the first vacuum cleaner sucks the dust in the dust collection chamber of the second vacuum cleaner into the basic dust collection cavity of the base station by such connection. In this case, the valve can also be a tongue valve or similar valve.

The invention further proposes that the valve is suitable for opening the fluid connection between the air duct of the second vacuum cleaner and the basic dust collecting chamber when the air duct of the second vacuum cleaner is connected to the second air inlet and the second air outlet. According to this technical solution, the user of this base station does not need to manually adjust the valves in the area of the air inlets and air outlets. Specifically, the valves are automatically switched when the second vacuum cleaner is connected to the base station, thereby forming a fluid connection between the second vacuum cleaner and the base station and the first vacuum cleaner.

The invention proposes that the valve can be switched, for example, by the mechanical action of the section of the second vacuum cleaner. The section of the second vacuum cleaner can be, for example, the end region of the suction channel, which acts mechanically on the valve. Among them, the valves in the area of the air inlets and the valves in the area of the air outlets can be subjected to this mechanical action. For example, it may simply be mechanically pushing or knocking off the valve tongue or the like.

In addition, the valve can be connected with an electromechanical valve control device, which controls the valve according to the connection state of the second vacuum cleaner on the second air inlet and/or the second air outlet. Wherein, the valve control device includes, for example, a sensor system, which recognizes whether a second vacuum cleaner is provided on the base station. In this case, the corresponding operation signal is transmitted to the valve or valves. In this regard, the base station may have, for example, electrical contact points, which can recognize that the section of the second vacuum cleaner is particularly close to the base station in a corresponding shape, so that, for example, it can be determined not only whether a second vacuum cleaner is connected to the base station, but also It can be determined whether the second vacuum cleaner conforms to a specific vacuum cleaner type that can be sucked by the base station.

The base station can also be adapted between the first vacuum cleaner and the base station, and/or Or a closed flow circuit is established between the first vacuum cleaner and the second vacuum cleaner. This closed flow circuit is constructed in such a way that the fan (suction side) of the first vacuum cleaner sucks air from its basic dust collection chamber and the dust collection chamber of the first or second vacuum cleaner connected to the basic dust collection chamber. The chamber is again connected to the fan (pressure side) of the first vacuum cleaner.

In order to increase the benefit of the base station to users, the present invention supplementally proposes that the base station has a charger, which can be connected to the battery of the first vacuum cleaner and/or the second vacuum cleaner. In this way, not only the vacuum cleaners arranged on the base station can be cleaned/emptied, but also their batteries can be charged at the same time. Therefore, the user does not have to worry about having no vacuum cleaner to carry out several maintenance tasks continuously, and to be precise, different maintenance tasks (ie, emptying and battery charging) are carried out simultaneously.

In addition to the aforementioned base station, the present invention also proposes a vacuum cleaner system having the base station of the present invention, a first vacuum cleaner corresponding to the base station, and a second vacuum cleaner also corresponding to the base station. The so-called vacuum cleaner corresponds to the base station means that the vacuum cleaner and the base station have compatible air connectors. The vacuum cleaner system may have, for example, a hand-held vacuum cleaner as the first vacuum cleaner, and a vacuum cleaner robot as the second vacuum cleaner. According to any of the foregoing embodiments, the base station adopts a technical solution such that the air ducts of the vacuum cleaners can be connected to the base dust collection chamber of the base station in such a way that between the first vacuum cleaner and the base station, and at the first vacuum cleaner Establish a closed flow circuit with the second vacuum cleaner. Therefore, the vacuum cleaner system can clean different vacuum cleaners. For example, only the first vacuum cleaner can be connected to the base station, so that only the dust collector can be cleaned by its fan, or both the first and second vacuum cleaners can be connected to the base station. , Also clean the dust chamber of the second vacuum cleaner by the fan of the first vacuum cleaner. Of course, in addition to the first and second vacuum cleaners, this vacuum cleaner system may also have other vacuum cleaners. Within the scope of the present invention, these other vacuum cleaners are also defined as second vacuum cleaners. In principle, it can also be cleaned by the fan of the second vacuum cleaner The dust collecting room of the second vacuum cleaner. In this regard, it is the first vacuum cleaner.

In addition to the base station and the vacuum cleaner system, the present invention also proposes a method of using the vacuum cleaner system of the present invention to clean and/or empty the dust collecting chamber of the second vacuum cleaner, wherein the first air inlet and the first air outlet of the base station are connected to The air duct of the first vacuum cleaner, and the second air inlet and the second air outlet of the base station are connected to the air duct of the second vacuum cleaner, wherein the dust collector of the second vacuum cleaner is then contained by the fan of the first vacuum cleaner The dust is transported to its basic dust collection chamber. Therefore, the method of the present invention can clean the dust collecting chamber of the second vacuum cleaner through the fan of the first vacuum cleaner. Advantageously, the first vacuum cleaner may be a hand-held vacuum cleaner, and the second vacuum cleaner may be a robot vacuum cleaner (robovac). The dust collecting chamber of the vacuum cleaner robot usually has a small volume, and therefore needs to be cleaned frequently.

The first vacuum cleaner 3 is, for example, a hand-held rechargeable vacuum cleaner, and the second vacuum cleaner is, for example, a self-moving cleaning robot. The base station 1 has a housing that can accommodate at least the sections of the first and second vacuum cleaners 3 and 4 in the housing in a form-fitting manner, so that the vacuum cleaner system 19 is generally as small as possible after assembly Structural form.

FIG. 2 shows a first vacuum cleaner 3 connected to the base station 1, wherein the vacuum cleaner is housed in a section of the housing of the base station 1 in a form-fitting manner.

3 shows the base station 1 to which the first and second vacuum cleaners 3 and 4 are connected, wherein the second vacuum cleaner 4 automatically moves below the corresponding section of the base station 1.

As shown in FIGS. 1 to 3, the first vacuum cleaner 3 and the second vacuum cleaner 4 each have a suction port 17 and a discharge port 18, wherein the suction port 17 is used to suck dust into the dust collection chambers 5, 6 of the vacuum cleaners 3, 4. The discharge port 18 is used to discharge the air cleaned by the air filter 16 to the cleaners 3 and 4.

FIG. 4 shows a first embodiment of the present invention. According to this embodiment, only the first vacuum cleaner 3 is connected to the base station 1. As shown in the schematic sectional view, the base station 1 has a basic dust collection chamber 2, a first air inlet 7 and a first air outlet 8, and the first air inlet 7 and the first air outlet 8 are in fluid connection with the basic dust collection chamber 2, and A connector for the first vacuum cleaner 3 is provided. A filter bag is beneficially arranged in the basic dust collection chamber 2, and dust entering the dust collection chamber 5 can be collected in the filter bag. In addition to the first air inlet 7 and the first air outlet 8, the base station 1 further has a second air inlet 12 and a second air outlet 13. These air inlets and air outlets are used to connect to the second vacuum cleaner 4. In the flow path between the first air inlet 7 and the second air inlet 12, and in the flow path between the first air outlet 8 and the second air outlet 13, valves 14, 15 are arranged, respectively, in the second vacuum cleaner 4 When connected to base station 1 and needs to be cleaned, its The valve can be deflected from the first position to the second position.

The first vacuum cleaner 3 is connected to the flow path of the base station 1 through its suction port 17, discharge port 18, and additional cleaning port 21. In addition, the first vacuum cleaner 13 has a dust collecting chamber 5 in which an air filter 16 is inserted, and this air filter 16 is here a permanent filter. The dust collecting chamber 5 is connected to the fan 11 of the first vacuum cleaner 3 through the air duct 9. During the normal suction work of the first vacuum cleaner 3, the air duct 9 sends air from the suction port 17 to the fan through the air filter 16 11. Among them, the dust contained in the sucked air enters the air filter 16 and is collected in the dust collection chamber 5. Therefore, only the dust-removed air flows to the fan 11 and escapes from the discharge port 18.

The basic dust collecting chamber 2 is also connected to the air duct 9 through the connecting pipe 22. In this regard, a negative pressure can be generated in the basic dust collection chamber 2 through the fan 11. The connecting pipe 22 also intersects the connecting pipe 23 connecting the discharge port 18 and the first discharge port 8 (when the valve 15 is in the position shown in FIG. 4). In this case, there is no fluid connection between the connecting pipe 22 and the connecting pipe 23.

In the exemplary cleaning mode of the first vacuum cleaner 3, the discharge port 18 of the first vacuum cleaner 3 is connected to the first exhaust port 8 of the base station 1, and the suction port 17 of the first vacuum cleaner 3 is connected to the base station 1. The first air inlet 7 is in fluid connection. The second air inlet 12 and the second air outlet 13 of the base station 1 are closed by the valves 14, 15 so that the surrounding air does not pass through the second air inlet 12 or the second air outlet 13 to enter the base station 1 or the first vacuum cleaner 3.

The cleaning of the first vacuum cleaner 3 may be manually initiated by the user, or, alternatively, when a sensor (not shown) arranged on the base station 1 recognizes that the first vacuum cleaner 3 is connected to the base station 1, for example, Way to start. After that, the fan 11 is started and the vacuum cleaner valve 20 arranged in the air duct 9 of the first vacuum cleaner 3 is closed, so that the wind The duct 9 is disconnected in a fluid technology and the fan 11 is no longer in direct fluid connection with the dust collection chamber 5. The air delivered by the fan 11 passes through the discharge port 18 of the first vacuum cleaner 3 and passes through the flow channel formed in the base station 1 to enter the dust collection chamber 5, where the air is delivered to the air filter 16 from the inside so that the air It flows through the air filter 16 in the opposite direction to the normal flow direction of the suction operation of the first vacuum cleaner 3. The dust and dirt deposited outside the air filter 16 are carried away by the air flowing from the inside to the outside, and pass through the suction port 17 of the first vacuum cleaner 3 and enter the first air inlet 7 of the base station 1. Thereafter, the air laden with dust enters the basic dust collection chamber 2, is filtered by a filter (for example, a filter bag) arranged in the basic dust collection chamber 2, and flows back from the basic dust collection chamber 2 as clean air To the fan 11 of the first vacuum cleaner 3. Thus, a closed flow circuit is formed.

FIG. 5 shows a second embodiment of the present invention. According to this embodiment, both the first vacuum cleaner 3 and the second vacuum cleaner 4 are connected to the base station 1. The first vacuum cleaner 3 is connected to the base station 1 as shown in FIG. 4.

The second vacuum cleaner 4 also has a dust collecting chamber 6 and a fan 11, and the dust collecting chamber 6 has an air filter 16. The dust collection chamber 6 and the fan 11 are connected to each other through the air duct 10.

The base station 1 may have a sensing mechanism (not shown), for example, a touch sensor, which recognizes whether the second vacuum cleaner 4 is present on the second air inlet 12 and the second air outlet 13. A valve control device (not shown) can control the valves 14 and 15 to fluidly connect the suction channel 10 of the second vacuum cleaner 4 to the basic dust collection chamber 2 and the fan 11 of the first vacuum cleaner 3. The valve 14 is operated in such a way that there is a fluid connection between the second air inlet 12 and the basic dust collection chamber 2. Accordingly, the valve 15 is operated so that the second exhaust air There is a fluid connection between the port 13 and the fan 11 of the first vacuum cleaner 3. Beneficially, the vacuum cleaner valve 20 inside the air duct 9 of the first vacuum cleaner 3 is also automatically closed.

The fan 11 of the first vacuum cleaner 3 is activated to clean or empty the dust collection chamber 6 of the second vacuum cleaner 4. Through the correspondingly operated valves 14, 15 and the vacuum cleaner valve 20, a discharge opening 18 of the first vacuum cleaner 3, a second exhaust outlet 13 of the base station 1, and a second vacuum cleaner 4 that flow through the exhaust opening 18 of the first vacuum cleaner 3 are formed The air duct 10, the second air inlet 12 of the base station 1, the basic dust collection chamber 2, and finally return to the closed flow circuit of the fan 11 of the first vacuum cleaner 3 again. In this regard, the fan 11 of the first vacuum cleaner 3 cooperates with the dust collection chamber 6 of the second vacuum cleaner 4 so that the dust contained in the dust collection chamber 6 of the second vacuum cleaner 4 is conveyed through the fan 11 of the first vacuum cleaner 3 To the basic dust collection chamber 2 of the base station 1, and in the basic dust collection chamber 2, the collected dust can be finally removed. Since only the fan 11 of the first vacuum cleaner 3 is used for cleaning the dust collection chamber 5 of the first vacuum cleaner 3 and the dust collection chamber 6 of the second vacuum cleaner 4, the base station 1 itself does not need its own fan.

Except for the above illustrated embodiment, of course, for example, the valves 14, 15, 20 may be operated in other ways, other types of valves 14, 15, 20 may be provided, or the air inlets 7, 12 and the air outlets 8, 13 may be provided at the base station 1. Variations of other spatial locations within. In addition, the base station 1 may be supplemented with manual or electromechanical valve control devices or the like.
