Technical Field

The invention relates to a wet and dry vacuum cleaner having a cleaner head/dirt container and an inlet fitting designed for connecting a suction hose. The inlet fitting is in flow connection with an inlet connection of the wet and dry vacuum cleaner in the wet and dry vacuum cleaner, so that the sucked-in dirt particles can pass through the inlet connection into the dirt container.

Background

Wet and dry cleaners of the type mentioned at the outset are known in principle from the prior art. These wet and dry cleaners are used, for example, to suck away dirt particles which typically occur, for example, when working with an abrasive cutting machine. For this purpose, a suction hose is connected to the inlet fitting, which suction hose is in turn connected, by way of example, to a milling machine. In so-called wet applications, dirty water is sucked in. In dry applications, only or primarily dry dirt particles are sucked in.

Disclosure of Invention

It is an object of the present invention to provide a wet and dry vacuum cleaner having improved operating characteristics.

This object is achieved by the diffuser having the intake nipple designed as a horizontal outflow.

The present invention includes the following recognition: in wet and dry cleaners of the prior art, the inlet fitting and/or the inlet nipple are typically positioned in the cleaner head, whereby the existing volume of the dirt container can be optimally utilized. In this case, the intake nipple is typically directed directly into the dirt container, which leads to an undesired lifting and swirling of the already sucked-in dirt particles in the dirt container. It has been observed that: this results in premature shut-down in wet applications and relatively short filter life in dry applications. These disadvantages can be avoided by the way the inlet connection is designed according to the invention as a diffuser with a horizontal outflow. Rather, the layer-by-layer introduction of dirt particles into the dirt container is promoted without turbulence in the dirt container.

It has proven advantageous: the suction flow is directed through the intake connection designed as a diffuser toward the inner wall of the dirt container. The rebound of the suction flow from the inner wall slows down or slows down the sucked-in air with the dirt particles, which leads to a further improvement of the introduction of the dirt particles into the dirt container.

Preferably, the inner wall of the dirt container is a side wall of the dirt container. The inner wall need not necessarily be a side wall of the dirt container. Rather, the inner wall can also be a further wall inside the wet and dry vacuum cleaner, which is oriented vertically and/or whose area is at least as large as the cross section of the diffuser opening into the nozzle.

In a particularly preferred embodiment, the inlet socket designed as a diffuser has a diffuser opening, the wall spacing of which from the inner wall is less than one fifth of the container width of the dirt container.

The cross section of the diffuser opening is preferably at least 50% greater than the cross section of the inlet fitting in the region of the wall channel leading into the dirt container.

The diffuser opening may (preferably only) be arranged in the upper third of the dirt container.

It has proven advantageous: the inlet socket, which is designed as a diffuser, is arranged in the volume defined by the dirt container. In a particularly preferred manner, the inlet socket embodied as a diffuser is arranged exclusively in the volume defined by the dirt container.

It is particularly preferred that the wet and dry vacuum cleaner has an electric turbine provided in the cleaner head. The wet and dry vacuum cleaner can have a dirt filter which is connected downstream of the intake connection in the form of a diffuser with respect to the suction flow.

In a further preferred embodiment, the inlet stub designed as a diffuser is designed in one piece. The inlet socket designed as a diffuser can be integrally formed on the dirt container. The intake nipple designed as a diffuser is preferably made of plastic or polymer.

Drawings

Other advantages result from the following description of the figures. A preferred embodiment of the present invention is shown in fig. 1. The figures, description and claims contain many combinations of features. The person skilled in the art suitably also considers these features individually and combines them into other combinations which are meaningful.

Detailed Description

A preferred embodiment of a wet and dry vacuum 100 according to the present invention is shown in figure 1. The wet and dry vacuum cleaner 100 has a cleaner head 10, a dirt container 20 and an inlet fitting 25 configured for connection of a suction hose 200.

A suction hose 200 to be connected to the inlet fitting 25 is schematically shown in fig. 1.

The wet and dry vacuum cleaner 100 also has an inlet connection 27, which is in flow connection with the inlet fitting 25 in such a way that the sucked-in dirt particles P can pass into the dirt container 20 via the inlet connection 27.

As can be seen from fig. 1, the intake connector 27 is designed according to the invention as a diffuser with a horizontal outflow.

As can be seen from the figures, the inlet connection 27, which is designed as a diffuser, is arranged only in the volume V defined by the dirt container 20. Furthermore, a diffuser configured as an inlet nozzle 27 is provided, so that the suction flow S is directed directly toward the inner wall 21 of the dirt container 20. In other words, the suction flow S flows through the diffuser opening 28 of the intake nozzle 27 in the horizontal direction H toward the inner wall 21, rebounds from the inner wall and enters into the lower region of the dirt container 20 in a slowing manner, as a result of which the dirt particles P can be introduced layer by layer without turbulence or at least with a significantly reduced turbulence.

As can also be seen from fig. 1, the diffuser opening 28 entering the connection piece 27 has a wall distance WA from the inner wall 21, wherein the wall distance WA is less than one fifth of the container width B of the dirt container 20.

In the present exemplary embodiment, the cross section Q1 of the diffuser opening 28 is at least 50% greater than the cross section Q2 of the inlet fitting 25 in the region of the wall channel leading into the dirt container 20.

The wet and dry cleaner 100 of figure 1 also has a motor turbine provided in the cleaner head 10. By means of the electric turbine, a suction flow S is generated, via which dirt particles P are sucked into the dirt container 20 during wet or dry use.

The wet and dry vacuum cleaner 100 also has a dirt filter 17, which is connected downstream of the intake connection 27, which is designed as a diffuser, with respect to the suction flow S. In the presently illustrated embodiment, a dirt filter 17 is provided in the transition between the cleaner head 10 and the dirt container 20.

The cleaner head 10 is placed on the dirt container 20 from above and locked thereto (locking means not shown). In the preferred embodiment of fig. 1, the inlet socket 27, which is designed as a diffuser, is designed in one piece and is integrally molded directly onto the dirt container 20. The intake connector 27 and the dirt container 20 are both made of plastic.

In an alternative embodiment, the dirt container 20 can be made of metal, for example, into which an inlet socket made of plastic or polymer, for example, is fitted together with an inlet fitting 25 made of plastic or polymer.
