Description

Cleaning device and base for the cleaning device

This creation relates to a cleaning device with a dust collecting chamber, in particular a combined suction-wiping device.

In addition, this creation is about a pedestal that can be connected to a cleaning device to perform a service.

Furthermore, the present invention also relates to a system comprising a base and a cleaning device, wherein the cleaning device has a dust collecting chamber.

In the prior art, cleaning devices and pedestals of the above type are known.

In the simplest case, the cleaning device described above may be a pure suction cleaning device having a dust collecting chamber, or a cleaning device capable of performing both a dry cleaning task and a wet cleaning task. The latter, for example, has both a liquid system for wetting the surface to be cleaned and a suction system for collecting the objects to be sucked from the surface to be cleaned. For example, the liquid in the new tank of the cleaning device can be released onto the cleaning elements of the cleaning device, such as the cleaning drum, or it can be released directly onto the surface to be cleaned. The contaminated liquid can then be sent to the dirty tank.

During the suction operation of the cleaning device, the object to be absorbed collected from the surface to be cleaned is transferred to the dust collecting chamber by the fan, and then can be manually removed by the user, for example, together with the filter bag, or can be sucked off by the base. .

Based on the prior art described above, the purpose of this creation is to improve the cleaning apparatus and the base so that the dust collection chamber can be emptied in an alternative manner.

In order to achieve the above object, the present invention first proposes that the cleaning device has a jet pump having a first pump inlet, a second pump inlet having a flow connection with the dirt collection chamber, and a pump outlet. In particular, it is proposed that the first pump inlet is connected to the new tank and that the pump outlet is connected to the tank. Among them, the new liquid tank and the dirty liquid tank are especially preferably installed in the cleaning equipment. As an alternative, the new tank and the sump can also correspond to the pedestal.

By using a jet pump, the regeneration of the dust collecting chamber can be combined particularly advantageously with other regeneration tasks, such as a new tank and/or a sewage tank of a rinsing cleaning device. Since the jet pump has two pump inlets and one pump outlet, the new liquid from the new tank and the to-be-primed material can be simultaneously transferred to the sewage tank and disposed or discharged therefrom. Wherein the object to be sucked contained in the dust collecting chamber is sent to the dirty liquid tank based on the suction effect of the fresh liquid passing through the jet pump. In this way, the user of the cleaning device does not have to manually empty the dust collecting chamber, so that the cleaning device can work longer without the necessity of curing. Similarly, the sump can be rinsed with fresh liquid. If necessary, the dirty liquid tank of the cleaning device can be taken out from the cleaning device and manually emptied, or automatically emptied on the base, that is, the dirty liquid is transferred from the dirty liquid tank of the cleaning device to the dirty liquid tank of the base. In addition, the sewage tank of the cleaning device can be directly connected to a drainage pipe (for example, a washing machine) and directly connected to the domestic drainage system.

This creation uses a jet pump, which is advantageous in that the jet pump operates only on the water pressure of the fresh liquid without the need for a power supply. Furthermore, unlike other types of pumps, the jet pump does not have a moving component that would, for example, be obstructed by coarse grained objects. Therefore, spray The jet pump is also particularly suitable for transporting heavily contaminated liquids.

In particular, the creation proposes that the cleaning device has a new liquid pump, the pressure side of which corresponds to the first pump inlet of the jet pump. Accordingly, the new fluid pump is responsible for generating the necessary inlet pressure at the first pump inlet of the jet pump, which ultimately contributes to the suction effect required to empty the dust collecting chamber inside the jet pump. The new liquid pump can be, for example, a diaphragm pump, a gear pump or the like. The new liquid pump only needs to be suitable for conveying clean fresh liquid. As an alternative, it is also possible to use a domestic water supply to provide the pressure required to operate the jet pump, for example by connecting the new tank of the cleaning device or the first pump inlet of the jet pump directly to the domestic faucet.

The present invention further proposes that a new tank is provided in the through-flow connection between the new liquid pump and the jet pump. As an alternative, if the new tank is connected to a domestic fresh water supply system, the present proposal proposes that the new tank is located between the domestic water supply joint and the jet pump. Thereby, fresh liquid is forced out of the new tank and reaches the first pump inlet of the jet pump at the required pressure. Alternatively, the suction side of the new liquid pump, rather than the pressure side of the new liquid pump, can be connected to the new tank. In this case, the new liquid pump will draw fresh liquid from the new tank and deliver this fresh liquid on its pressure side to the first pump inlet of the jet pump.

Furthermore, the flow connection between the dust collecting chamber and the jet pump can advantageously have a filter, in particular the dust collecting chamber itself can advantageously have a filter. The filter is adapted to prevent clogging of the flow conduits inside the cleaning device. In particular, the filter is advantageously arranged in the dust collecting chamber such that coarse particles which may be present in the dust collecting chamber do not enter the pipe but are trapped in the dust collecting chamber. The coarse material can be manually disposed of by the user of the cleaning equipment. As an alternative, the coarse material can also be automatically sucked up on the base, wherein the coarse material is transferred to the base through a corresponding flow connection between the dust collecting chamber of the cleaning device and the dust collecting chamber of the base.

The cleaning device proposed by the present invention may in principle be a self-moving cleaning device or a cleaning device manually operated by a user. The cleaning device can be configured, for example, for cleaning the floor surface, but can also be used to clean areas above the floor, such as for cleaning window panes, gantry partitions, skirting boards, and the like. Furthermore, the cleaning device can be configured primarily for performing wet cleaning tasks or for performing dry cleaning tasks. This creation proposes to use a suction-wiping robot as the cleaning device.

In addition to the aforementioned cleaning apparatus, the present invention further proposes a base that can be connected to a cleaning device to perform a service behavior, wherein the base has a jet pump having a first pump inlet, in particular a new liquid with the base The tank has a first pump inlet connected by a flow connection; a second pump inlet for connecting the cleaning device; and a pump outlet, in particular a pump outlet having a flow connection with the sewage tank. Accordingly, the jet pump of the base of the present invention has the advantages and functions described in connection with the cleaning device. In this way, the wet cleaning device itself does not have to have its own pump corresponding to the dust collecting chamber, especially the jet pump, so that the object to be sucked can be removed from the dust collecting chamber of the wet cleaning device. Specifically, the jet pump is disposed in the base and is used, for example, to flush the new tank and the sewage tank of the base, and on the other hand, to transfer the object to be sucked from the dust collecting chamber of the wet cleaning device to the base. Sewage tank. The pump inlet of the jet pump is connected to the new tank on the one hand and to the dust collecting chamber of the cleaning device on the other hand. The pump outlet of the jet pump opens into the dirty tank of the base. Through the suction effect of the fresh liquid flowing into the sewage tank from the new tank, the object to be sucked is sucked out from the dust collecting chamber of the cleaning device and sent to the dirty liquid tank together with the fresh liquid. The sump tank of the pedestal can advantageously be connected to the domestic drain connection so that the effluent can be drained directly out of the sump. The new tank of the pedestal can also be connected directly to the domestic water supply connection, making it particularly easy to obtain fresh liquid. In addition, the water pressure required to operate the jet pump is also provided by the domestic water supply joint. As an alternative, the sump tank and/or the new tank may also be detachably disposed in the base and may be removed by the user of the base and added Manually empty, clean and fill.

The present invention further proposes that the base has a new liquid pump, the pressure side of which corresponds to the first pump inlet of the jet pump. The new liquid pump can, for example, be connected to the new tank on its pressure side and deliver fresh liquid from the new tank to the first pump inlet of the jet pump. It is especially recommended to use a new liquid pump in case the base is not connected to a domestic water supply joint but to form a separate system.

In particular, the creation proposes that a new tank of the base is provided in the flow connection between the new liquid pump and the jet pump. The new liquid pump thereby presses fresh liquid from the new tank into the jet pump. Alternatively, a new liquid pump can be placed between the new tank and the jet pump so that the new pump draws fresh liquid from the new tank and delivers it to the first pump inlet of the jet pump.

In addition to the aforementioned cleaning apparatus and the aforementioned pedestal, the present application also proposes a system consisting of the pedestal and the cleaning apparatus, wherein the cleaning apparatus has at least one dust collecting chamber. According to the present invention, the base has a jet pump having a first pump inlet, in particular a first pump inlet in flow connection with a new tank of the base; a second pump inlet; and a pump outlet, In particular, there is a pump outlet connected to the dirty liquid tank of the base, wherein the second pump inlet can be connected to the dust collecting chamber of the cleaning device when the cleaning device is in a state of docking the base. Accordingly, the susceptor is configured to draw the object to be sorbed from the dust collecting chamber of the cleaning device by the jet pump and transfer it to the sump tank of the susceptor. Thus, in the case of liquid pipes and dust passages, the base and the cleaning device are configured to correspond to each other and to be interconnected to effect the regeneration operation of the system. In addition to the dust collecting chamber, the cleaning device can of course also have a new tank and a dirty tank. Thus, the cleaning device can be a pure vacuum cleaner or can be a combined suction-wiping device. The new tank of the cleaning device can be connected to the new tank of the base to fill the fresh water, while the tank of the cleaning device can be connected to the corresponding tank of the base to transfer the dirt to the base.

The present invention further provides that the base and/or the cleaning device has a new liquid pump, the pressure side of which corresponds to the first pump inlet of the jet pump. According to this technical solution, the liquid can be applied to the first pump inlet of the jet pump by means of a new liquid pump of the base or a new liquid pump of the cleaning device. In this way, the pressure required to operate the jet pump can also be generated by cleaning the new liquid pump of the device itself. In addition, both pump inlets may also be supplied by components of the cleaning device (ie, the new tank of the cleaning device itself and the dust collection chamber of the cleaning device). Alternatively, the base alone may have a new tank and a new liquid pump, which provides the new fluid pressure required to operate the jet pump.

In both cases, the new tank can be placed in the flow connection between the new pump and the jet pump. Wherein, the pipe section including the new liquid pump in the throughflow connection may be disposed in the base or the cleaning device. In both cases, the pressure side of the new fluid pump is connected to the new tank of the base.

The authors finally propose that the cleaning device has a new tank that can be connected to the new tank of the base and/or a tank that can be connected to the tank of the base. As described above, it is thereby advantageously possible to fill the new tank of the cleaning device through the susceptor and empty the sump of the cleaning device on the pedestal.

The second pump inlet 7 is connected to the dust collecting chamber 4, and the pump outlet 8 is connected to the dirty liquid tank 3. A valve 29 is provided between the new tank 2 and the jet pump 5. A valve 30 is also provided between the jet pump 5 and the dirty tank 3. On the side of the new tank 2 opposite the jet pump 5, a new liquid conduit 22 projecting from the cleaning device 1 is provided. Furthermore, on the side of the dirty tank 3 facing away from the jet pump 5, a dirty liquid conduit 23 which likewise projects out of the cleaning device 1 is provided. The dust collecting chamber 4 is connected to the jet pump 5 through the dust passage 34. A new liquid pump 9 is provided in the new liquid pipe 22. Further, a dirty liquid pump 28 is provided in the dirty liquid pipe 23. The dust collecting chamber 4 has a filter 10 adapted to filter the coarse particles to be sucked at the junction with the dust passage 34, so that only fine particulate matter such as dust can be sucked into the dust passage 34 from the dust collecting chamber 4. The cleaning roller 26 can also be seen in FIG. The cleaning roller corresponds to a drum housing 41 that at least partially surrounds the cleaning roller 26.

The susceptor 11 has a new tank 12 and a sump tank 13. The new liquid conduit 24 extends outwardly from the new tank 12 to the base housing 19. Further, the dirty liquid pipe 25 projects outward from the dirty liquid tank 13 to the base housing 19 (see also FIG. 1). The new tank 12 and the dirty tank 13 are detachably provided in the base housing 19 of the base 11. When the cleaning device 1 is in the state of the docking base 11 shown here, the dirty liquid pipe 23 of the cleaning device 1 and the dirty liquid pipe 25 of the base 11 are connected to each other, and the new liquid pipe 22 of the cleaning device 1 is connected to the base. 11 new liquid pipe 24.

According to this embodiment, the working principle of the present creation is, for example, as follows: To carry out a conventional wiping operation, the cleaning device 1 first receives fresh liquid from the new tank 12 of the susceptor 11. To this end, the new liquid pump 9 of the cleaning device 1 draws fresh liquid from the new tank 12 of the base 11. Fresh liquid can then be applied to the cleaning drum 26 in a conventional manner to wet the surface to be cleaned. The cleaning drum 26 collects the dirty liquid during the wiping operation. This dirty liquid is transferred to the dirty tank 3 via the drum housing 41 directly during the wiping operation and/or subsequently during the regeneration operation. Further, during the suction operation of the cleaning device 1, the object to be sucked is sucked into the dust collecting chamber 4 from the surface to be cleaned.

In order to carry out regeneration of the dust collecting chamber 4 and the dirty liquid tank 3 of the cleaning device 1, the cleaning device 1 is connected to the base 11, which is realized by connecting the new liquid pipes 22, 24 and the dirty liquid pipes 23, 25 to each other. During the regeneration operation, it is necessary to transfer the object to be sucked contained in the dust collecting chamber 4 to the dirty liquid tank 13 of the susceptor 11. Further, it is also necessary to transfer the dirty liquid contained in the dirty liquid tank 3 of the cleaning device 1 to the dirty liquid tank 13 of the susceptor 11 and flush the dirty liquid tank 3 with fresh liquid. To this end, the valves 29, 30 corresponding to the new tank 2 and the dirty tank 3 are opened, thereby opening the flow path from the new tank 2 to the dirty tank 3 via the jet pump 5. The new liquid pump 9 passes fresh liquid from the new tank 12 of the base 11 via the new liquid tube The track 24 is fed into the new tank 2 of the cleaning device 1 and from there to the first pump inlet 6 of the jet pump 5. The fresh liquid is delivered to the dirty tank 3 by the jet pump 5 there. In the meantime, a suction force is generated inside the jet pump 5, and this suction force sends the object to be sucked from the dust collecting chamber 4 to the jet pump 5 via the dust passage 34 and to the pump outlet 8 of the jet pump 5. Both the fresh liquid and the object to be sorbed enter the septic tank 3 via the open valve 30 where it is mixed and further fed into the sump tank 13 of the susceptor 11 via the effluent conduit 23. The dirty liquid pump 28 provided in the dirty liquid pipe 23 can supportably suck the dirty liquid from the dirty liquid tank 3 and feed it into the dirty liquid tank 13 of the susceptor 11. Once the regeneration operation is complete, the valves 29, 30 can be closed again. The dirty tank 13 of the base 11 can be manually emptied by the user. Similarly, the new tank 12 of the base 11 can also be manually refilled by the user.

FIG. 3 shows a second embodiment in which the base 11 has a new tank 12, a dirty tank 13 and a jet pump 14. The jet pump 14 establishes a through-flow connection between the new tank 12 and the dirty tank 13, wherein the first pump inlet 15 of the jet pump 14 is connected to the new tank 12, and wherein the pump outlet 17 of the jet pump 14 is connected to the dirty liquid Box 13. The jet pump 14 further has a second pump inlet 16 that connects the dirt passages 35. The dust passage 35 projects from the base housing 19 of the base 11. A valve 32 is provided between the new tank 12 and the jet pump 14. A valve 33 is also provided between the jet pump 14 and the dirty tank 13. The new liquid line 24 extends from the new tank 12 beyond the base housing 19. A new liquid pump 18 is provided in this new liquid line 24. The dirty liquid pipe 25 projects from the dirty liquid tank 13 outside the base housing 19. A dirty liquid pump 31 is provided in this dirty liquid pipe 25. In addition, the new tank 12 is further connected to a connecting duct 38 which projects out of the base housing 19 and which can be connected to a domestic water supply joint. The dirty tank 13 is connected in the same manner to the connecting duct 37 which also protrudes from the base housing 19. This connecting duct 37 can be connected to a domestic drain joint. Valves 36 are provided in the connecting conduits 37, 38, respectively.

The cleaning roller 26 of the cleaning device 1 corresponds to the drum housing 41, the roller The cartridge housing has a discharge port 40 that opens into the dirty liquid tank 3 and an inlet port 39 that connects the new liquid tank 2.

According to this second embodiment, the working principle of the present creation is, for example, as follows: To implement different service behaviors, the cleaning device 1 can be connected to the susceptor 11. This includes, for example, charging the battery of the cleaning device 1 by a charging station (not shown) of the susceptor 11. Further, fresh liquid can be transferred from the new tank 12 of the susceptor 11 to the new tank 2 of the cleaning apparatus 1 via the new liquid conduits 22, 24. A new liquid pump 18 of the base 11 is activated for this purpose. Further, the dirty liquid can be transferred from the dirty liquid tank 3 of the cleaning device 1 to the dirty liquid tank 13 of the susceptor 11 via the dirty liquid pipes 23, 25 while the dirty liquid pump 31 is in operation. The new liquid conduit 22 and the dirty liquid conduit 23 of the cleaning device 1 each have a valve 42 in the end region of the outwardly extending conduit.

During the wiping operation of the cleaning device 1, the effluent is continuously transferred from the cleaning roller 26 to the sump 3 through the discharge port 40 of the drum housing 41. In order to wet the cleaning drum 26, fresh liquid is released from the new tank 2 through the inlet port 39 of the drum housing 41 onto the cleaning drum 26. During the suction operation of the cleaning device 1, the object to be sucked is transferred to the dust collecting chamber 4 of the cleaning device 1 in a conventional manner (suction channel not shown).

In order to carry out regeneration of the dust collecting chamber 4, the cleaning device 1 is connected to the base 11, so that the cleaning devices 1 and the dust passages 34, 35 of the base 11 are connected to each other. Next, the jet pump 14 of the base 11 is manipulated to regenerate the dust collecting chamber 4 of the cleaning device 1, that is, to transfer the object to be sucked from the dust collecting chamber 4 to the dirty liquid tank 13 of the base 11. For this purpose, the valves 32, 33 are opened and fresh liquid is supplied to the new tank 12 through the connecting duct 38. Fresh liquid enters the sump 13 through the jet pump 14 and valves 32,33. In the meantime, a suction force is generated on the second pump inlet 16 of the jet pump 14, which sucks the object to be sucked from the dust collecting chamber 4 of the cleaning device 1. Next, the object to be sorbed can be transferred to the domestic drain pipe through the connection pipe 37 along with the liquid contained in the dirty liquid tank 13.

After the regeneration operation is finished, the base 11 is again closed corresponding to the jet pump The valves 32, 33 of the 14 cause the new tank 12 and the dirty tank 13 of the susceptor 11 to pass through the jet pump 14 without a flow connection.
