Description

Dry and/or wet vacuum cleaners

The present invention relates to a dry and/or wet vacuum cleaner, in particular to a vacuum cleaner with a water filter.

As is known, dry and/or wet vacuum cleaners basically fall into two categories: towed devices and so-called "electric brooms".

In the first type of equipment, all functional elements such as suction means, steam generating means, filtering and collecting means for sucking solids or liquids are enclosed to be towed in a body arranged on wheels, which can be A hose is connected to which several accessories are connected, which can be replaced when required.

In an electric broom, the functional element is applied to the handle and/or to the guide base at the end of the broom.

In any case, the versatility of use of these devices is limited to the possibility of mounting a certain number of interchangeable accessories while the structure of the base remains unchanged.

There are also smaller vacuum cleaners that can be moved and operated with one hand but have lower power. In practice they are often used in very limited applications, such as for vacuuming debris.

On the one hand, it is an object of the present invention to provide a dry and/or wet vacuum cleaner that will be very versatile.

In particular, the device is configured with a range of attachments to convert from a towed device to a power broom, from a backpack vacuum cleaner and vice versa as required.

Said objects and related advantages are achieved by a dry and/or wet vacuum cleaner according to at least claim 1 .

Further characteristics and advantages of the present invention will become clearer from the following description with reference to the reference numerals and the non-limiting drawings, in which:

Figure 1 shows a perspective view of a vertical section of a dry and/or wet vacuum cleaner according to the present invention;

Figure 2 shows an exploded perspective view of the device;

Figure 3 shows in detail the connection system between the motor assembly and the device;

Figure 4 represents a front view of the device;

Figure 5 shows an exploded perspective view of the motor assembly; and

Figure 6 shows the motor assembly in the construction of a dry vacuum cleaner with some accessories.

According to a conventional embodiment, said dry and/or wet vacuum cleaner comprises a body enclosing first means for collecting and filtering liquids and/or solids and suction means, wherein said body can be connected with at least one suction and/or or cleaning attachment combination, said apparatus characterized in that said suction means comprises a motor assembly detachable from said body and adapted to accommodate a second means for collecting solids and/or liquids for its own Operates as a vacuum cleaner.

In said figures, reference numeral 10 generally designates the body of a dry and/or wet vacuum cleaner. The body 10 is provided on wheels 11 to be towed. The body houses two side tanks 12 containing water and/or detergent, a central tank 13 for collecting water and/or solids, and steam generating means such as an evaporator 14 . The central tank 13 also functions as a water filter and is easily removed from the body 10 for its emptying and cleaning. On its front side, the body 10 has a connection piece 15 for connecting a hose 16, at the free end of which hose 16 can be connected various accessories for suction and/or cleaning, such as an inlet 17, Brush 18, electric carpet sweeper. More specifically, the connection 15 comprises a first inlet 19 for connecting a pipe for suctioning solids and/or liquids, a second inlet 20 of smaller diameter for connecting a pipe for distributing steam or water and/or cleaning agent , and a multi-pole socket 21 for electrically connecting said device with a remote control device provided on the handle 16 ′ of the hose 16 .

Furthermore, the body 10 has at least one pump 22 for continuously replenishing the evaporator 14 and for injecting water and/or cleaning agent into the washing attachment.

The suction function of the device is realized by a motor assembly 23 connected to the body 10 . It is found that the motor assembly 23 is detachably connected to the opening 24 formed in the rear recess of the body 10 so that the motor assembly 23 can be accessed from the outside to facilitate removal from the body 10 .

The motor assembly is directly powered by a power source via a cable 25 which can for example be plugged into a grip handle 26 provided on the same motor assembly.

According to a preferred embodiment of the present invention, when the motor is applied to the body 10, it transfers electrical energy through an electrical connection between a multi-pole socket 27 disposed on the motor assembly and an electrical plug 28 disposed on the body 10 such as adjacent to the opening 24. to the body 10 , in particular to the evaporator 14 .

Once removed, the container 29 with the filter 29' for dust recovery and one of the accessories provided with the above equipment can be applied to the motor assembly. Additionally, the belt can be connected to the motor assembly with attachments.

The motor assembly can thus become a small but powerful vacuum cleaner, an electric broom, and a backpack vacuum cleaner.

In other words, the user is able to switch from the use of conventional towing equipment to the use of electric brooms, or backpack vacuum cleaners, for example to more easily clean curtains and glass, or simply Converts to a small and powerful vacuum cleaner.

It should be noted that the technology used to realize the device allows the use of a motor assembly with low consumption, but which has a high suction efficiency and is particularly light so that it can be easily moved.
