Description
Technical Field
The invention relates to a pump device for a household appliance, in particular a washing machine or a rinsing machine for laundry or dishes. In household appliances such as washing machines or washing machines, for reasons of efficiency and to improve the washing result, it is then provided that the household appliance is equipped with a water circulation system, in which cleaning fluid or process water is supplied to the washing process in a repeated manner. Here, the efficiency of the washing process is significantly improved by transporting the dirt particles several times. However, in any case, the arrangement of an additional pump for this additional process represents an additional expenditure.
Background
Document DE 1460948 a1 includes a pump assembly for a washing machine for selectively delivering a liquid to be pumped by means of a change in the direction of rotation of a pump shaft. Two pump wheels are arranged on the pump shaft, at least one of which is provided with an axial vane, wherein each pump wheel is surrounded by its own pump housing provided with two connection pieces, and wherein the arrangement is such that only one pump wheel delivers liquid in each direction of rotation.
Disclosure of Invention
The object on which the invention is based is to provide a cost-effective pump device for a domestic appliance.
According to the invention, the object is achieved by a pump device, wherein the pump device comprises a drive device having a first impeller for operating the pump device in a first operating state in a first conveying direction in order to pump fluid out of the household appliance and a second impeller for operating the pump device in a second operating state in a second conveying direction in order to cyclically pump fluid inside the household appliance, wherein a first idle drive is arranged between the drive device and the first impeller and a second idle drive is arranged between the drive device and the second impeller in order to always drive only the first impeller or only the second impeller depending on the first operating state or the second operating state. Thereby, technical advantages such as: only one drive can satisfy two independent requirements, which are predefined by the pump-out (Abpumpen) and the circulation pump-out (umpen). Furthermore, it is thus possible to simply control the hydraulic system for pump-out and circulation pumping in such a way that only the direction of rotation of the drive is changed. This makes it possible to achieve a compact design of the pump device within the domestic appliance, since no dedicated pump has to be provided for each operating state.
An Impeller (Impeller) in the sense of this specification comprises in particular a Propeller (Propeller) surrounded by an annular or tubular housing.
In one embodiment, it is provided that the first impeller and the second impeller are of identical design.
In one embodiment, it is provided that the coupling or connection between the first impeller and the drive device has no coupling (kuppleng) which acts in two opposite rotational directions, in particular no coupling which acts in two opposite rotational directions and is electromagnetically driven. This achieves, in particular, the technical advantages of: the mechanical construction is simply constructed and a simple and reliable connection or coupling is formed between the first impeller and the drive means.
In one embodiment, it is provided that the coupling or connection between the second impeller and the drive device has no coupling that acts in two opposite directions of rotation, in particular no coupling that acts in two opposite directions of rotation and is electromagnetically driven. This achieves, in particular, the technical advantages of: the mechanical construction is simply constructed and a simple and reliable connection or coupling is formed between the second impeller and the drive means.
In order to also construct the pump device more compactly, the first impeller and the second impeller are connected to the drive device by means of a common drive shaft (antitriebsachse). It is therefore possible for the connection between the drive device and the drive shaft to be constructed particularly simply and inexpensively, since no second drive shaft connected to the drive device is provided. This additionally reduces the assembly effort of the pump device during production.
In order to achieve the compactness required for a pump device with the requirement of two operating states acting independently in a particularly simple manner, the first impeller and the second impeller are arranged on mutually opposite sides of the drive.
In order to design the delivery capacity of the pump device, or in other words the normal operation (fulnitieren) of the operating state in which the washing lye is pumped out of the household appliance into the waste water network, particularly effectively, the pump device comprises a first pressure chamber, which is assigned to the first impeller. By rotation of the first impeller inside the first pressure chamber, the washing lye thus flows from the first pressure chamber into the waste water network.
In order to design the delivery capacity of the pump device, or in order to design the normal operation of the operating state in which the washing lye is pumped around inside the domestic appliance, the pump device comprises a second pressure chamber, which is assigned to the second impeller. By rotation of the second impeller inside the second pressure chamber, the washing lye flows out of the second pressure chamber. For example, the washing lye can subsequently be re-supplied to the washing process in the domestic appliance.
In order to keep the household appliance or the pump device as free as possible from disturbances or malfunctions, or to keep maintenance costs of the household appliance as low as possible, the first pressure chamber and the second pressure chamber are each connected to a fluid container (in particular a lye container) of the household appliance by means of a separate, autonomous fluid connection. This can be achieved, for example, by: in the event of contamination or clogging of the pump device, the two fluid connections do not necessarily clog, or the two pressure chambers do not necessarily interfere. Therefore, the above two operation states do not stop operating at the same time, and the home appliance can be operated in a limited manner. Furthermore, each fluid connection and each impeller can be cleaned or repaired independently of the respective operating state.
Preferably, however, the pump device has a common suction chamber for the first pressure chamber and for the second pressure chamber. In this way, only one connecting line is required between the pump device and the fluid container of the domestic appliance. Through this connecting line, when the pump device is operated, fluid is sucked from the fluid container into the suction chamber of the pump device. It is not essential here which of the two blades is operated.
Preferably, inside the pump device there is configured: a first fluid connection from the suction chamber to the first pressure chamber, and a second fluid connection from the suction chamber to the second pressure chamber. In this way, there is no need to install a separate and independent connecting line between the suction chamber and the first or second pressure chamber. This makes the assembly process much easier.
The first fluid connection is in particular designed as a suction connection (Saugstutzen). Advantageously, the suction chamber is arranged directly in front of the first pressure chamber in the axial direction. The flow through the suction chamber into the first pressure chamber is determined by the cross section of the suction connection. Advantageously, the suction chamber is separated from the first pressure chamber by only one wall, wherein the wall has an opening. The opening is advantageously designed as a suction connection. The suction connection piece projects in particular into the suction chamber.
The second fluid connection is formed in particular as a channel in the housing of the pump device. Advantageously, the second fluid connection extends in the axial direction over the dimension of the pump device from the suction chamber up to the second pressure chamber. Advantageously, the second fluid connection opens centrally with reference to the impeller into the second pressure chamber.
Advantageously, a common filter device for the first fluid connection to the first pressure chamber and for the second fluid connection to the second pressure chamber is arranged in the suction chamber. Thus, only one filter device is required for the two fluid connection arrangements described above. The filter device may have different through openings, for example for the first or second fluid connection.
In order to additionally increase the maintenance and cleaning advantages of the pump device, the filter device is exchangeable. The replaceable filter device can be designed as a calcium filter, as a fluff sieve, as a foreign-matter trap or as various other filter devices.
In order to increase the maintenance advantages, in particular for the user of the household appliance, the filter device is arranged to be accessible to the user. In other words, the filtering device has the characteristics of: this feature makes it possible for a user to easily remove the filter device from the household appliance, for example by means of a plug-in connection or a screw connection, and to replace a clogged or defective filter device by a new filter device. Advantageously, the filter device can be replaced manually, for which no special tools need to be used. For example, the filter device can be configured to be accessible to a user by means of an externally accessible control flap.
According to a particularly preferred embodiment, the pump device is designed for operation in a third operating state, wherein the first pressure chamber is designed to be fluidically connected to the second pressure chamber. This can be achieved, for example, by means of an additional valve arrangement, which is designed as a simple three-way valve. The first pressure chamber and the second pressure chamber can thus be cleaned by operation of the pump device and by operation of the first impeller or the second impeller and can be subjected to additional functional tests. This may be particularly advantageous, in particular, if the compact design of the pump device does not allow a user or a person skilled in the art, who is faced with repair, repair or cleaning of the pump device or the household appliance, to have simple access to the first and second pressure chambers. In some embodiments, access to only one pressure chamber is much simpler than access to two pressure chambers separately, and in particular in these embodiments, operation in the third operating state has proven to be particularly advantageous.
These idle running drive means are arranged on the pump device between the drive means and the first impeller and between the drive means and the second impeller, in particular in cooperation with these idle running drive means, the first impeller being designed for operation in a second direction of rotation and the second impeller being designed for operation in a second direction of rotation opposite to the first direction of rotation. This makes it possible to achieve a particularly independent and simple control of the hydraulic system of the pump device. By a simple selection of the direction of rotation of the drive, either pumping out of the fluid or circulating pumping of the fluid in the domestic appliance can be achieved.
In order to achieve the drive described above particularly simply and cost-effectively by applying the existing technology, the drive comprises a brushless direct current Motor (BL DC-Motor).
According to a particular embodiment, the pump device comprises a closure (Verschluss) for cleaning purposes or for maintenance purposes. The closure element can be designed here as an alternative or in addition to the already mentioned maintenance flap or control flap of the domestic appliance. In this case, it is conceivable, for example, to configure the closure such that the first impeller and/or the second impeller can be replaced.
According to a further particular embodiment, the pump device is configured to drive the second impeller by mechanical movement of the first impeller. Thus, it is possible, for example, to set the functionality of the pump device, which is provided for a complete and thorough cleaning of the pump device, the first pressure chamber, the second pressure chamber, the first impeller and the second impeller, in addition to the already mentioned closures. This can be done, for example, by a mechanical connection of the first impeller and the second impeller, in order to achieve a force transmission from the first impeller to the second impeller or vice versa. The operating mode of the first and second idle drives can thus be briefly interrupted in order to carry out cleaning of the pump device. Following the cleaning that has been carried out, the mechanical connection can be released again and the initial state of the pump device can be established again.

The object is achieved by the subject matter having the features according to the independent claims. Advantageous embodiments of the invention are the subject of the figures, the description and the dependent claims. The figures show:

FIG. 2: schematic illustration of a pump apparatus.
Detailed Description
Fig. 1 shows a schematic representation of a household appliance 100, for example in the form of a washing machine, having a pump device 103. In the upper region of the household appliance 100, a fluid container 101, for example in the form of a lye container, is arranged, which fluid container 101 is designed to receive a fluid (for example a cleaning or caustic wash) and to wash items. A pump device 103 arranged directly below the fluid container 101 is designed to pump fluid or alkaline cleaning liquid out of the fluid container 101 into a waste water network 104. Furthermore, the pump device 103 is designed to pump the fluid or caustic wash from the fluid container 101 in a circulating manner inside the domestic appliance 100. In other words, the household appliance 100 is designed to recirculate the caustic washing liquid conveyed out of the fluid container 101 into the fluid container 101 as required, in order to reuse the liquid for the washing process.
Fig. 2 shows a schematic illustration of the pump device 103. The pump device 103 comprises a drive 105, which drive 105 is configured, for example, as a brushless direct current Motor (BLDC Motor). The drive means 105 is supplied with energy via a current supply means 108. Additionally, the drive device 105 is connected to a first impeller 107 and a second impeller 109. Here, the first impeller 107 and the second impeller 109 have a common drive shaft 106, wherein a first idle drive 119 and a second idle drive 121 are arranged on the common drive shaft 106 between the drive device 105 and each impeller (i.e. between the drive device 105 and the first impeller 107 and between the drive device 105 and the second impeller 109), respectively. The first and second idle drives 119, 121, which are assigned to the first and second impellers 107, 109, respectively, are designed in such a way that only the first impeller 107 is driven by the rotation of the common drive shaft 106 of the drive device 105 in the first direction of rotation, wherein the idle drive 121 assigned to the second impeller is such that the second impeller is not driven. However, if the drive device 105 is moved in a second rotational direction opposite to the first rotational direction and the common drive shaft 106, which is designed in connection with the drive device 105, is moved in the corresponding second rotational direction, only the second impeller 109 is operated by the drive device 105. The first impeller 107 is arranged on the common drive shaft 106 by means of a first idle drive 119, whereby the first impeller 107 does not rotate with it when rotating in the second direction of rotation. The drive device 105 thus drives the common drive shaft 106 in a direction of rotation, depending on which only one of the two impellers is always able to be operated, i.e. either the first impeller 107 in the case of driving the common drive shaft 106 in a first direction of rotation or the second impeller 109 in the case of driving the common drive shaft 106 in the opposite or second direction of rotation.
In order to be able to operate the first impeller 107 and the second impeller 109 independently of one another and in order to enable the operation of the pump device 103 for the first and second conveying directions depending on the direction of rotation, the pump device 103 comprises a first pressure chamber 113 assigned to the first impeller 107 and a second pressure chamber 115 assigned to the second impeller 109. In this case, the first pressure chamber 113 is supplied with fluid via the first fluid connection 125 by means of the suction chamber 124 of the pump device 103 in order to use the pump device 103 for operation in a first conveying direction (for example for conveying fluid or caustic wash liquid from the fluid container 101 from the household appliance 100 into the waste water network 104). The first pressure chamber 113 is assigned to the first impeller 107, or the first impeller 107 is arranged in the first pressure chamber 113. By the rotation of the first impeller 107, the alkaline washing liquid is thus caused to flow from the first pressure chamber 113 into the waste water network 104. Similarly, in order to operate the pump device 103 in the second conveying direction in order to circulate the fluid or caustic wash liquid from the fluid container 101 inside the household appliance 100 and to reuse the caustic wash liquid used in this way for a washing process inside the household appliance 100, a second fluid connection 126 between the suction chamber 124 of the pump device 103 and the second pressure chamber 115 of the pump device 103 is then realized. Since the second impeller 109 is located inside the second pressure chamber 115, a flow of caustic wash liquid out of the second pressure chamber 115 in the second transport direction is thus generated by the rotation of the second impeller 109. For example, the caustic wash liquid can then be fed back to the washing process in the household appliance 100. I.e. it is thus possible to control the function of the pump device 103 or to control the conveying direction of the pump device 103 by controlling the direction of rotation of the drive means 105.
A common filter device for the first fluid connection 125 to the first pressure chamber 113 and for the second fluid connection 126 to the second pressure chamber 115 can be arranged in the suction chamber 124. Thus, only one filter device is required for the two fluid connections described above. The filter device may for example have different through openings for the first or second fluid connection structures.
In order to additionally increase the maintenance advantages of the pump device 103 and to increase the cleaning advantages of the pump device 103, the filter device can be exchanged. The replaceable filter device can be designed as a calcium filter, as a fluff screen, as a foreign-matter trap, or as various other filter devices.
Additionally, the pump device 103 has a closure 123 for cleaning or servicing of the pump device 103. The closure 123 may be fixed to the housing of the pump device 103, for example by means of a screw thread or other simple fixing means. Such a closure 123 enables better access to the first impeller 109 for cleaning purposes or for maintenance purposes. Likewise, it is conceivable, for example, to arrange a further closure on the pump device 103 to enable access to the second impeller 109 inside the second pressure chamber 115.
Alternatively, fluid connections which are independent and independent of one another can also be provided between the fluid container 101 and the first pressure chamber 113 and the second pressure chamber 115. In this case, the household appliance 100 is particularly not susceptible to disturbances that may be caused by blockages. Therefore, in the event of contamination or clogging of the pump device 103, the two fluid connection structures described above are not necessarily clogged, and therefore the two pressure chambers described above are not necessarily disturbed. Thus, neither of the above-mentioned two operating states may stop operating, and, however, the household appliance 100 may have a limited operation. Here, both the fluid connection for the first pressure chamber 113 and the fluid connection for the second pressure chamber 115 each have a replaceable filter device. These filter devices are arranged to be accessible to a user of the household appliance. In other words, the filter device has properties that enable a user to easily remove it from the household appliance 100, for example by means of a plug connection or a screw connection, and to replace a clogged or defective filter device by a new filter device. These filter devices can be replaced manually without the use of special tools for this purpose. For example, these filter devices can be designed to be accessible to the user via an externally accessible control flap (kontrolklappe).
All features explained and illustrated in connection with the individual embodiments of the invention can be provided in different combinations in the subject matter according to the invention in order to achieve their advantageous effects at the same time.
