Definitions

  • the invention relates to a vacuum cleaner with a control unit and a dirt collecting container, which has a suction inlet and is connected via a suction with a suction unit in flow communication, which is connected via at least one air duct with at least one air outlet.
  • dirt and preferably liquid can be sucked by applying the dirt collector using the suction unit with negative pressure, so that forms a suction flow from the suction inlet through the dirt collecting through the suction to the suction unit. From the suction unit, the sucked air can be passed through an air duct to an air outlet of the vacuum cleaner.
  • an electronic control system is used, which in many cases has heat-dissipating power semiconductors and / or electromechanical relays.
  • the operation of the suction unit is associated with a certain noise, which should be kept as low as possible, and the use of the control electronics is associated with a certain heat generation, which should also be kept low, and in the case of excessive heat to ensure that heat-sensitive components of the vacuum cleaner will not be damaged.
  • a vacuum cleaner according to the preamble of claim 1 is made EP 0 289 987 A known.
  • GB 2 337 922 A discloses a vacuum cleaner in which the suction motor is enclosed by a sound-absorbing, flame-retardant mat.
  • JP 08038401 A discloses a vacuum cleaner in which the printed circuit board is covered by an insulating, refractory fabric.
  • Object of the present invention is to develop a vacuum cleaner of the generic type such that in a structurally simple manner the noise can be kept low and heat-sensitive components can be protected from damage.
  • a vacuum cleaner of the type mentioned according to the invention that at least one air duct is sealed by means of a sound-insulating sealing mat, which is made of a flame-retardant material and covers the electrical control unit.
  • the sealing mat not only makes it possible to design the air channel flow-tight and compensate for example, manufacturing tolerances in the manufacture of the air duct, but in addition, the sealing mat forms a fire protection in the event of heavy heating of the control electronics.
  • the sealing mat covers the control electronics and is made of a flame-retardant material.
  • the sealing mat thus assumes several functions. It forms a sound insulation, so that the noise of the vacuum cleaner is reduced. In addition, it allows a flow-tight completion of the air duct, whereby manufacturing tolerances of the air duct can be compensated. In addition, the sealing mat forms a fire protection, which ensures that with a strong warming of the control electronics of the vacuum cleaner does not easily start on fire.
  • the sealing mat can be simple Be mounted so that the vacuum cleaner according to the invention can be configured in a structurally simple manner such that it shows a relatively low noise and has a reliable fire protection.
  • the sealing mat is elastically deformable. This gives the possibility of compressing the sealing mat during assembly, where it is then eager to take their original shape again and thereby creates a fluid-tight against adjacent walls and edges of the vacuum cleaner.
  • the sealing mat is made of a foamed Duroplast material.
  • Thermosets are cross-linked plastics that do not melt even at relatively high temperatures.
  • the sealing mat covers the control electronics, so that reliable fire protection is ensured in the case of a strong heating of the control electronics due to the flame-retardant property of the sealing mat.
  • the sealing mat is made of a foamed thermoset material from the group of aminoplasts.
  • foamed thermosets based on PUR material could also be used.
  • the sealing mat has a thermal conductivity of less than 0.04 W / mK, in particular less than 0.035 W / mk.
  • the thermal conductivity is measured at a temperature of 10 ° C and is determined according to the DIN standard 52612. It has been found that a sealing mat with such a thermal conductivity value is particularly suitable for protecting the remaining components of the vacuum cleaner against damage in the event of a strong heating of the control electronics.
  • the vacuum cleaner on a housing part with a hood which covers a partition wall part, wherein the partition wall part has a bottom, projecting from the spaced apart two partitions defining therebetween an air duct, and wherein the sealing mat between the hood and is arranged the partitions.
  • the partition wall part may have a U-shaped profile, which is formed by the bottom and the two partitions and which is covered by the cover with the interposition of the sealing mat.
  • the control electronics are preferably arranged laterally next to one of the partitions outside the air duct. It can comprise at least one printed circuit board on which electrical components are arranged. The circuit board can be fixed to the partition.
  • control electronics are connected to at least one cooling element, for example a cooling plate, which protrudes into the air duct.
  • the partition on the outside of the control electronics is arranged, have an opening which is penetrated by the cooling element.
  • the suction unit is covered by the sealing mat.
  • the sealing mat not only extends over the air duct and the control electronics, but also covers the suction unit. This makes it possible to keep the noise of the vacuum cleaner particularly low. It is advantageous if the suction unit is arranged in an upper part of the vacuum cleaner, which can be placed on the dirt collecting container.
  • the suction unit comprises a forced-air-cooled electric motor, which is connected via a first air duct with a cooling air outlet, and a suction turbine driven by the electric motor, which is connected via a second air passage with a Saugluftauslass, wherein the sealing mat seals the first and the second air passage.
  • a suction flow to the suction unit can be achieved starting from the suction inlet through the dirt collecting container and the suction line.
  • the sucked air can be discharged via the second air duct to the Saugluftauslass the vacuum cleaner.
  • this is supplied independently of the suction air cooling air, which can be discharged via the first air duct and the cooling air outlet to the environment.
  • the suction unit can thereby have a considerable suction capacity. Because the soundproofing Sealing mat seals both the first and the second air duct and the air ducts preferably covered over the entire surface, the flow of cooling air and the suction air can be optimized in terms of the lowest possible noise of the vacuum cleaner.
  • the electronic control system is electrically connected to at least one electromagnetic closing valve, which closes a forced air inlet, wherein the external air intake, the side facing away from the dirt collector side of a filter arranged in the flow path between the dirt collector and the suction unit for impingement with external air is abruptly acted upon.
  • at least one electromagnetic closing valve which closes a forced air inlet, wherein the external air intake, the side facing away from the dirt collector side of a filter arranged in the flow path between the dirt collector and the suction unit for impingement with external air is abruptly acted upon.
  • the outside of the dirt collecting container side of the filter can be acted upon by external air by the electromagnetic closing valve is opened, so that via the outside air inlet foreign air can flow into the suction.
  • the filter cleaning is controlled by the control electronics, which therefore has a not inconsiderable heat development.
  • the risk of damage to components of the vacuum cleaner in case of improper overheating of the control electronics is kept low by the present invention used for use sealing mat.
  • an electromagnet for closing the closing valve can be acted upon with electricity, wherein the power supply is timed interruptible.
  • the solenoid of the closing valve is acted upon by the control unit with an excitation current, so that a magnetic field is formed, which holds the closing valve in its closed position. If a filter cleaning be made, the excitation current is interrupted by the control unit for a short time. This has the consequence that the magnetic field of the electromagnet breaks down and thereby opens the closing valve. Foreign air can then act suddenly on the side facing away from the dirt collector side of the filter and thereby mechanically shake the filter.
  • control unit can be flowed through in the counter-current direction, that is, in contrast to the prevailing during the normal suction suction flow of external air, thereby effectively to be cleaned.
  • an exciter current is permanently provided by the control unit. This can result in a considerable heating of the control unit. Since, however, the control unit according to the invention is covered by the flame-retardant sealing mat having a low thermal conductivity, there is practically no danger that the heat development of the control unit will impair other components of the vacuum cleaner.
