Description

[0001] VACUUM CLEANER.

[0002] FIELD OF TECHNOLOGY.

[0003] The invention relates to dust cleaning equipment, namely to vacuum cleaners with a liquid filter.

[0004] To date, domestic and foreign vacuum cleaners with fabric or paper filters have been widely used, but these have a number of significant drawbacks. When these filters become dirty, the vacuum cleaner's suction capacity decreases. After each use, the vacuum cleaner requires shaking the dust bag, which creates inconvenience.

[0005] STATE OF THE ART.

[0006] In recent years, vacuum cleaners with a cyclonic dust collector have become increasingly widespread [1].

[0007] The disadvantage of this type of vacuum cleaner is that the best and most effective cyclone designs capture no more than 95% of dust. 5% of dust, including the finest and therefore most harmful particles, as well as mold spores, viruses, and other contaminants, are not captured by cyclones and remain suspended in the room air. One of the latest advances in this area is the use of water filters, which capture fine dust, mold spores, and even viruses [2].

[0008] However, the shape and placement of the filter on the vacuum cleaner body, the location and design of the air duct connection, the fasteners, and the inspection and cleaning openings make attaching and detaching the filter, as well as cleaning it, quite inconvenient. Furthermore, for the same reasons, as well as due to the relative position of the filtering devices, the filter is complex to manufacture, has a large volume, and is large in relation to the cross-section of the filtering devices.

[0009] A vacuum cleaner is known that contains a housing, a pipe for supplying air to be cleaned of dust, a cleaning chamber in which the cleaned air interacts with water, and a pipe for discharging air cleaned of dust [3].

[0010] In a conventional vacuum cleaner, air goes through at least two stages of purification: the first mechanical purification is carried out in a glass covered with a metal mesh, and the second - in a purification chamber partially filled with water, through which bubbles of purified air are passed.

[0011] In the known device, the disadvantage is the labor-intensive nature of handling the vacuum cleaner during its periodic cleaning.

[0012] In most known solutions, the liquid reservoir is located in the main body as a tray at the bottom. When cleaning the vacuum cleaner, this location requires additional manipulation of the main body, specifically opening the vacuum cleaner body and rinsing it.

[0013] A vacuum cleaner is known that includes an air intake pipe, a liquid reservoir, and an air outlet pipe. The air intake has an air outlet end located in the liquid reservoir and has a cross-sectional area that gradually increases along the direction of liquid flow within the air intake. [4]

[0014] However, even this vacuum cleaner does not guarantee 100% dust removal. This is because air bubbles passing through a layer of water have a relatively small surface area for mass transfer with the water. Consequently, the smallest dust particles contained in the air bubbles are not completely captured by the water, but are carried away with the air passing through the water into the atmosphere of the room being cleaned. Furthermore, large debris with long stripes, such as hair and long fibers, will block the suction port, while small debris will settle on the bottom of the vacuum cleaner body. This makes it difficult to operate the vacuum cleaner and subsequently clean the body and suction port, making the wet vacuum cleaner less user-friendly at all stages.

[0015] ESSENCE OF THE INVENTION.

[0016] The purpose of the claimed device is to increase the efficiency of cleaning the sucked-in air, reduce the dimensions and weight of the device, simplify the design of the vacuum cleaner and increase the ease of use of a vacuum cleaner with a liquid filter.

[0017] The stated problem is solved due to the fact that in a vacuum cleaner, comprising a housing, a branch pipe for supplying air cleaned of dust, a reservoir with liquid, in which the cleaned air interacts with water, and a branch pipe for discharging air cleaned of dust, according to the invention, in the reservoir with liquid a branch pipe for supplying a contaminated air flow is installed, the lower edges of which have slots, a mesh filter is additionally introduced inside the branch pipe for supplying the contaminated air flow, and, so that the incoming contaminated flow enters through the mesh filter, the slots of the branch pipe for supplying the contaminated air flow are located higher above the lower part of the mesh filter.

[0018] The distinguishing features of the proposed device from existing ones include a contaminated air inlet installed in the liquid reservoir, the lower edges of which are slitted. A mesh filter is additionally inserted into the contaminated air inlet. The slots in the contaminated air inlet are positioned higher than the bottom of the mesh filter, so that the incoming contaminated air passes through the mesh filter. For ease of handling during cleaning, the filter must be easily and quickly separated from the main body. The filter must be transported assembled to the cleaning site, preventing contamination of the room and requiring no safety precautions. The design must be simple, allowing for easy assembly, disassembly, and cleaning.

[0019] To achieve this, the vacuum cleaner is equipped with a dirty air inlet with slits at the bottom. A mesh filter is also inserted into the dirty air inlet, ensuring that the incoming dirty air passes through the mesh filter. The dusty air inlet is curved toward the bottom of the chamber for coarse air filtration. A powerful stream of dirty air enters the dirty air inlet. The air stream, striking the curved wall of the inlet, partially removes large debris, such as long hair and fibers. The majority of the debris settles in the mesh filter on the bottom.

[0020] The slots in the contaminated air intake pipe face the bottom of the vacuum cleaner and are positioned above the bottom of the mesh filter to prevent clogging. Fine air purification occurs when the contaminated air flow is mixed with a powerful jet in a liquid layer and separated into two layers. Gas bubbles escaping from the slots bubble through the lower liquid layer. They merge into streams that pass through the liquid layer and create a pseudo-boiling liquid, forming a gas-liquid suspension and ensuring the incoming airflow is free of particles.

[0021] The gas-liquid suspension is then directed through a fine-mesh screen mounted inside the liquid tank, ensuring high-quality removal of fine particles from the contaminated air stream. The resulting layer of moving foam has a highly developed surface area for absorbing the smallest particles and purifying the air stream. The air stream is then dried through a separator, and the purified air is discharged through the outlet pipe.

[0022] The listed distinctive features allow the liquid filter to be placed in a compact housing with a mesh filter located at the bottom of the vacuum cleaner housing, and a mesh filter attached to the bottom of the housing.

[0023] This allows the mesh filter to be easily attached to the vacuum cleaner by mounting it underneath the main body. This ensures that sediment does not spill when the mesh filter is moved within the vacuum cleaner body to the cleaning location. It also ensures uniform airflow distribution throughout the device. The filter is quickly and easily assembled from a small number of simple, easy-to-clean components.

[0038] DESCRIPTION OF THE INVENTION.

[0039] The vacuum cleaner contains a tank with liquid 1. In the body of the tank with liquid 1, a branch pipe for supplying contaminated air flow 2 and an outlet pipe 5 are mounted.

[0040] The lower edges of the pipe for supplying contaminated air flow 2 are made with slots 11.

[0041] A mesh filter 3 is additionally introduced inside the branch pipe for supplying contaminated air flow 2, and so that the incoming contaminated flow enters through the mesh filter 3, the slots 11 of the branch pipe for supplying contaminated air flow 2 are located above the lower part of the mesh filter 3 installed in the bottom of the housing 7 of the vacuum cleaner of the mesh filter 3. Above the branch pipe for supplying contaminated air flow 2 with slots 11 inside the housing of the vacuum cleaner, a fine-mesh mesh 6 is mounted, consisting of a frame and a fine-mesh mesh.

[0042] The vacuum cleaner works as follows.

[0043] A powerful stream of contaminated air enters the contaminated air supply pipe 2. The air stream, striking the curved wall of the pipe 2, partially releases large debris—sediment 8—such as long stripes, long hairs, and long fibers. The remaining debris—sediment 8—settles in the mesh filter 3 at its bottom. Slots 11 of the contaminated air supply pipe 2 face the bottom of the vacuum cleaner and are positioned above the lower portion of the mesh filter 3, which is secured to the mesh filter 3.

[0044] Fine purification of contaminated air occurs when a flow of contaminated air is mixed by a powerful jet within a liquid layer and separated into two layers. Gas bubbles, emerging from slits 11, bubble through the lower liquid layer. They merge into streams that pass through the liquid layer and create a pseudo-boiling liquid 9, forming a gas-liquid suspension and ensuring the purification of the incoming flow from particles.

[0045] The gas-liquid suspension flow 9 is then directed through a frame consisting of a fine-mesh net 6, secured within the body of the liquid tank 1, thereby ensuring high-quality purification of the contaminated air flow from fine particles. The resulting layer of mobile foam 10 has a highly developed surface area for absorbing the smallest particles and purifying the air flow. The air flow is then dried through a separator 4, and the purified air is discharged through an outlet pipe 5. To remove the mesh filter 3, simply detach the vacuum cleaner lid. The mesh filter 3 is then transported closed to the cleaning station, where it is disassembled into two simple, easily cleanable parts.

[0046] The use of the proposed invention improves the operational properties of the vacuum cleaner, namely, increases the efficiency of cleaning the sucked air and makes it convenient to separate, disassemble, clean and assemble all the devices of the liquid filter.
