Description

Arrangement of the cleaning solution container for the electric vacuum cleaner for wet vacuuming

Technical field

The present invention relates to an arrangement of a cleaning solution container of an electric vacuum cleaner for wet vacuuming which can vacuum wet dirt and water, in particular for cleaning carpets, upholstered furniture, windows and the like. The container consists of an outer container, an inner container and a suction chamber lid.

BACKGROUND OF THE INVENTION

The prior art technical solutions of the cleaning solution containers and the suction dirt containers are generally designed so that each of these containers is stored separately in an electric vacuum cleaner. This technical solution occupies a substantial part of the area of the electric vacuum cleaner for wet vacuuming and such a vacuum cleaner is too bulky. U.S. Pat. No. 5,735,017 discloses a vacuum cleaner comprising a contaminated liquid storage tank and a cleaning liquid storage tank, the storage tank being a resilient bag and may be arranged in a liquid storage tank.

SUMMARY OF THE INVENTION

The above mentioned drawbacks are largely eliminated by the arrangement of the cleaning solution reservoir of the electric vacuum cleaner consisting of an outer container, an inner container and a suction chamber lid, in which the inner container is arranged in the outer container so that between the inner wall an outer container and a space for cleaning solution is formed between the outer wall of the inner container. The inner container is provided at its upper end with a rim having a sealing groove provided with a gasket on its upper side and with a bottom groove formed on its underside, against which the outer container is terminated at its upper edge by a bearing surface. At the same time, the outer wall portion of the outer container forms part of the surface of the vacuum cleaner that extends beyond the side wall of the vacuum cleaner lid and the side wall of the vacuum cleaner housing.

An advantage of the present invention is the minimum volume of vacuum cleaner space required to form the dirt suction container and the cleaning solution container.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a partial axial section through the container for the cleaning solution; FIG. 2 shows a section through the sealing of the suction chamber lid on the inner container by means of a seal; axonometric side view of the outer wall of the outer container serving as a bumper.

DETAILED DESCRIPTION OF THE INVENTION

The cleaning solution container arrangement of the electric vacuum cleaner for wet vacuuming of FIGS. 1 and 2 consists of an outer container 2 and an inner container 3. The inner container 3 is received in the container 2 so that between the inner wall 11 of the outer container 2 and the outer the wall 12 of the inner container 3 is provided with a rim 16 at its upper edge having a sealing groove 22 formed on its upper side 23 provided with a seal 5 and a lower groove 18 formed on its underside 17 provided with a bottom 21 against which the outer container 2 terminates at the upper edge part 14 of the outer wall 12

At the same time, the outer container 2 forms part of the surface of the vacuum cleaner which extends both on the side wall 15 of the vacuum cleaner cover 8 and on the other side 13 of the vacuum cleaner housing 1.

The outer container 2 is inserted into the housing 1 of the vacuum cleaner. Into the outer container 2 is inserted the inner container 3 so that the bottom 21 of the groove 18 formed on the underside 17 of the rim 16 abuts the abutment surface 19 formed on the upper edge of the outer container 2. The inner container is closed over the seal 5 provided in the sealing groove 22 the upper side 23 of the flange 16 of the suction chamber cover 4. Dirt air is sucked into the inner vessel 3 through the inlet throat 9, separated from them in the suction chamber 6 and sucked through the outlet throat 10 into the vacuum cleaner unit. Between the outer wall 12 of the inner container 3 and the inner wall 11 of the outer container 2, a cleaning solution space 7 is provided, which is conveyed by means of a pump to the spray nozzle. Both containers are then closed by a lid 8 in the vacuum cleaner. The outer container 2 is made of a resilient material, the portion 14 of the outer wall 12 which extends beyond the side wall 15 of the vacuum cleaner cover 8 and the side wall 13 of the vacuum cleaner housing 1 serves as a buffer.
