CZ11489U1 - Vacuum cleaner for dry and wet dirt extraction - Google Patents

Description

Technical field

The technical solution concerns a vacuum cleaner for dry and wet cleaning of dirt, especially from floor coverings or upholstery.

Background Art

The currently known vacuum cleaner for dry and wet dirt extraction consists of an elongated box body which is provided with both a pair of wheel elements and a rotatable wheel, and an aggregate driving the fan for generating suction, with a vacuum cleaner in the space in front of the aggregate a filtering space designed to accommodate a removable container for receiving and storing liquid impurities. This filter space is covered with a hinged cover with a suction opening to which a hose is attached from the outside, and a paper bag filter from the inside when the vacuum cleaner is used for dry vacuuming.

The disadvantage of this design is that when changing from one vacuum cleaner operation to another or when removing trapped dirt from the vacuum cleaner, either the open liquid dirt container or the open paper bag filter is handled.

The essence of the technical solution

The above-mentioned disadvantages are eliminated by a vacuum cleaner for dry and wet dirt picking consisting of a body which is provided with both wheels of the pair of wheels and a turntable wheel, and an aggregate provided together with the exhaust grille and control flaps in the rear thereof, as well as a filter chamber adapted to receive. removable dry and wet scavenging catchers arranged in its front under a hinged cover in which an opening for a hose end is formed, according to the present invention, in that a transversely oriented wall is provided in the body separating the aggregate space from the filter space and comprising a suction opening of the aggregate, wherein a liquid detergent container fitted with an open, separate dirt collection compartment is removably located in the filter space and can be folded either by a lid for dry cleaning. cleaning in which a paper bag filter or wet cleaning lid is provided with working ribs, each of which is provided with an outlet channel connectable after the container has been folded onto the suction opening formed in the wall of the front portion of the back cover, its hole.

Furthermore, it is essential for this technical solution that in the hose end there is integrated a guide for the liquid cleaning agent into the wet cleaning nozzle, which can be connected to the passage and the container is made of a transparent material. wherein at least a portion of at least one of its side walls is provided with an outwardly projecting shoulder, the shape and size of which correspond to the shape and size of the open recess formed in the adjacent side wall of the body delimiting the filter space and whose outer surface is flush with the outer surface of the body side wall.

Finally, it is essential that the container is provided with a foldable and flexible handle.

The advantage of this design is that when changing from one vacuum cleaner operation to another, or when removing trapped debris from a vacuum cleaner, it does not manipulate with an open liquid dirt box or an open paper bag filter.

The advantage is also that the filter space cover can be opened with the end cap attached to it.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be described in more detail below with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a vacuum cleaner; Figure 2 is an axonometric view of a vacuum cleaner with a hose attached; FIG. 4 is an axonometric view of a vacuum cleaner showing the possibility of using one of its two interchangeable lids; FIG. 5 is a perspective view of the aggregate portion of a vacuum cleaner according to the present invention; 7 shows an axonometric view of the inside of the dry lid.

An example of a technical solution

1 and 2 is a type of horizontal vacuum cleaner, otherwise also called "canister". The vacuum cleaner consists of a body J which is provided with a transversely oriented separating wall 2 dividing the vacuum cleaner body J into a space for the aggregate 28 and a filter space. On the one hand, the travel of the vacuum cleaner in the rear part of the body 1 in the region of the aggregate 28 accommodates a pair of wheels 40, each of which is provided with a tire 41 which is made of flexible material and sprayed on the wheel 40.

In the front part of the body, two turntables 42 are provided with the wheels 43 provided with elastic material thereon. In the front part of the vacuum cleaner, an end piece 3 is integrated away from the aggregate 28 in the foldable cover 7 covering the filter space, which includes both a wet cleaning agent pressure passage 4 and a suction air opening 5. The terminal 3 is attached to the handle 6, which is part of the housing 7, by means of a flexible rib 8 which fits into the groove 9 formed in the handle 6 of the vacuum cleaner.

The cover 7 (Fig. 3) opens around the hinge 10 located at the front of the front part of the vacuum cleaner body J.

A rotary actuator 37 is disposed in the rear portion of the handle 6, with which the cam 38 is fixedly coupled to the groove 39 formed in the rear cover 20 of the vacuum cleaner. A cleaning solution container 11, which is made of a transparent material by a blow molding method, is removably arranged in the filter space and is provided on its side walls with an outwardly projecting shoulder whose shape and size correspond to the shape and size of the open recess formed in the adjacent side the wall of the body and the bounding filter space, the outer surface of which is flush with the outer surface of the side wall of the body J.

The container 11 is provided with a hinged and flexible handle 36 and a separate area 12 for collecting dirt is provided therein. The upper part of the container 11 is each formed by one of two interchangeable and interchangeable caps 13, 17, which differ in their function (FIG. 4).

The dry-cleaning lid 13 (FIGS. 4 and 7) is intended for vacuuming dry dust particles and is provided with retaining elements for this function, on the one hand, for holding a paper bag sequin 14 provided in the area 12 for collecting dirt and for catching, In the back of the treated, dust filter 15. In order to prevent the already drained dust particles from escaping when the lid 13 is removed for dry cleaning with the partially filled paper bag filter Γ4, the dry cleaning cover Γ3 is fitted with a stopper 16 which covers it for as long as it is removed. or at the time of its transport to the garbage, hole in paper bag filter] 4.

The wet cleaning lid 17 (FIG. 4) is adapted to vacuum liquids such that working ribs 18 are arranged thereon to produce the desired effect. In the rear part of the wet cleaning lid 17, a mechanism is then assembled from several moldings to interrupt the vacuuming of liquids when the dirt collection space 12 is filled with the liquid to be sucked.

From both of these lids 13, 7, the air is discharged by means of an outlet duct 19, which is formed at the same location on both lids 13, 17 and which can be connected (upon tilting the container ϋ) to the suction opening of the unit 28. This suction opening is arranged in a horizontal direction Each of the lids 13, 17 is also provided with an inlet duct which can be connected after opening the cover 7 to its opening 5.

In the aggregate space defined by the wall 2, a rear cover 20 (FIG. 6) is arranged, on which both a flap 21 for lowering the aggregate 28 and a flap 22 for controlling the power cable winch and a flap 23 for controlling the liquid pump are mounted. detergent. The position of the flaps 21, 22, 23 is provided by fitting the panel 24, which forms a rigid and closed unit with the rear cover 20 after assembly. After the adjusting disc 25 has been inserted and after the fullness of the paper bag signal filter 26 has been adjusted, a cover 27 of the fullness of the paper bag filtering signal 26 is inserted into the panel 24.

The vacuum cleaner assembly 28 (FIG. 5) is arranged between the lower cover 29 and the upper cover 30 in a vertical position and is held therein by an upper damper 31 and a lower damper 32. The dampers 31, 32 dampen the vibration of the aggregate 28 and at the same time form sealing surfaces they direct, separate and form the desired working air channels in the vacuum cleaner, together with the covers 29, 30.

The air outlet of these working air ducts is terminated at the rear of the vacuum cleaner with an exhaust grille 34 in which the filter 35 is mounted and which is arranged in the lower housing 29. The aggregate seal 33, which is produced in the lower part of the aggregate 28, is then mounted in its lower part. made of rubber and which, together with the housing 1 and the lower housing 29, form air channels for supplying cold cooling air to the aggregate 28 and for discharging warm air therefrom.
