Definitions

  • the present invention relates to a motor assembly for an electric motor driven household appliance, in particular for a vacuum cleaner.
  • the present invention further relates to a cleaning device.
  • Vacuum cleaners typically have an electric fan motor, which is usually located inside the vacuum cleaner housing and provides the suction power of the vacuum cleaner. Especially for reasons of comfort and to avoid unnecessary noise pollution for the environment there is always the need for vacuum cleaners to reduce the noise generated during operation of the vacuum cleaner in particular by the fan motor to a minimum.
  • a vacuum cleaner In order to reduce the noise emissions of a vacuum cleaner, various approaches exist. For example, it may be provided to surround the engine with a plurality of noise attenuating materials which are to absorb the sound waves generated by the engine and thus reduce the noise emissions. Additionally or alternatively, the lowest possible possible engines are installed in vacuum cleaners, which should already minimize the noise.
  • the blower motor is enclosed by a motor housing.
  • the fan motor is coupled to the motor housing via a toroidal damping element.
  • B-side is the fan motor in mounted integrally with the motor housing engine mount.
  • German patent application DE 41 00 858 A1 describes a vacuum cleaner with a blower unit, which is surrounded by an inner housing capsule, which is in turn leaving a flow space in an outer housing capsule between which and the housing of the vacuum cleaner, there is a free space in which vacuum cleaner generated by the blower unit air flow through the Flow space is guided to a provided on the vacuum cleaner housing outlet.
  • An improvement of the noise attenuation is achieved in that the flow space is connected directly to the outlet and the outer housing capsule is held supported by means disposed on its outer periphery, noise-damping support means in the vacuum cleaner housing.
  • the present invention is based on the object to provide a better engine arrangement.
  • the idea underlying the invention is to spatially separate the motor capsule of a cleaning device from the lower part of the housing.
  • the engine capsule is connected only to the receiving devices rigidly with the support domes of the lower part.
  • the motor capsule is vibration-isolated from the lower part of the housing or at least vibrationally decoupled so that only a very small proportion of the vibrations of the motor capsule is transmitted to the lower part of the housing. In this way, noise emissions of the cleaning device are significantly reduced.
  • the receiving devices are rigidly connected to the support domes of the lower part.
  • the motor capsule remains in all operating states on all sides spaced from the lower part of the housing.
  • those portions of the base which can vibrate more are located at previously defined points on the housing.
  • the predetermined housing points can be structurally designed such that they can absorb the vibrations of the engine capsule well and distribute it to the entire lower part. In this way, the noise of the vacuum cleaner during operation can be significantly reduced, which makes the use of the vacuum cleaner comfortable.
  • the support domes and the receiving devices are arranged on low-vibration zones of the housing.
  • the support domes and the receiving devices are arranged on particularly stiff and solid areas of the upper part and of the lower part.
  • the rigidity or strength of the lower part and the upper part for example, by constructive measures, such as be increased by the dimensioning of the wall thickness of the lower part and the upper part, by the provision of stiffening element and the like.
  • the support domes and / or the receiving devices are provided with reinforcing ribs.
  • the reinforcing ribs extend in longitudinal directions of the Auflagerdome or the receiving devices and can thus increase the strength and rigidity of Auflagerdome or recording devices in addition. As a result, vibrations of the engine capsule can be better forwarded from the receiving devices to the support domes.
  • exactly three support domes and exactly three receiving devices are provided.
  • three receiving devices are provided, which are each offset by approximately 120 ° with respect to the center of the engine capsule.
  • the vibrations of the motor capsule can be distributed evenly on the lower part of the housing.
  • the support domes are arranged asymmetrically in the lower part. This would then z. B. ensure proper mounting of the upper part of the housing.
  • At least some of the support domes are arranged on the edge and / or in the immediate vicinity of the edge of the lower part.
  • the case edge is particularly well suited for the placement of the support domes.
  • the edge of the lower part is provided with reinforcing ribs.
  • a plurality of reinforcing ribs extend around the entire edge of the base. In this way, the edge of the lower part is further reinforced and can absorb the vibrations better.
  • the support domes have a reinforcement.
  • the support domes can be reinforced in their mechanical strength by metallic inserts, which are inserted into the support domes or encapsulated in the manufacture of the lower part of plastic. This makes the connection between the receiving devices and the support domes even more stable, which is noticeable in a further reduction of the noise of the household appliance.
  • the fastening devices are designed as screws.
  • the screws may be formed, for example, steel, brass, titanium or plastic.
  • the shaped element for the screws can be designed, for example, as an external hexagon, head slot, head cross slot, internal hexagon (Allen), internal multiple tooth (Torx) or internal triangular.
  • Allen internal hexagon
  • Torx internal multiple tooth
  • the use of screws ensures easy assembly of the motor assembly.
  • screws provide a particularly strong and stable connection of the receiving devices and the support domes.
  • the motor capsule in the assembled state is spaced on all sides at least 5 mm, and more preferably at least 2 mm from the lower part. Such a design ensures that no vibrations are transmitted from the engine capsule at locations other than the receiving devices and the support domes on the lower part of the housing.
  • the housing is made of plastic.
  • plastic for example, ABS, HIPS and PP can be used as plastic for the housing.
  • all parts of the housing can be manufactured in an injection molding process. This contributes to a reduction in the manufacturing cost of the household appliance.
  • a blower motor is provided, which is arranged in the assembled state in the interior of the engine capsule and is completely enclosed by this.
  • the motor capsule is preferably, like the other parts of the housing, also made of plastic.
  • the engine capsule additionally reduces the noise of the vacuum cleaner, as it can absorb the sound waves generated by the fan motor.
  • sound insulating materials are arranged on the engine capsule.
  • Fig. 1 shows a perspective view of an upper part 3 and a lower part 4 of a housing 2 of a motor assembly 1 according to the invention.
  • the upper part 3 has a motor capsule 5.
  • the engine capsule 5 essentially comprises a motor capsule lower part 11 and a motor capsule upper part 12. Inside the motor capsule 5 is a blower motor 6 arranged, which is preferably completely enclosed by the motor capsule 5 in the assembled state of the motor assembly 1.
  • other components such as a fan motor control or damping mats for damping the sound waves generated by the fan motor can be arranged in the motor capsule 5.
  • the engine capsule 5 has a plurality of receiving devices 8, which are arranged at exposed locations of the upper part 3. In this embodiment, the engine capsule 5 has three receiving devices 8. However, it is also possible that more than three receiving devices 8 may be provided on the motor capsule 5.
  • the engine capsule 5 may also have four, six or eight receiving devices 8.
  • the receiving devices 8 of the motor capsule 5 are preferably provided with stiffening ribs 10, which are intended to increase the stability of the receiving devices 8.
  • a reinforcement is provided in the receiving devices 8, which further increase the rigidity and strength of the receiving devices 8.
  • the reinforcement can be formed for example by metal inserts, which are located in the receiving devices 8.
  • an increase in the rigidity of the receiving means 8 z. B. be realized by an incorporated glass fibers.
  • a design of the receiving means 8 of a fiber composite material is conceivable.
  • housing 2 is preferably formed of a plastic, which is particularly resistant to wear against mechanical stress.
  • the housing 2 is formed of a polyurethane-based plastic (PUR).
  • the lower part 4 has a trough-shaped form in the present embodiment.
  • the support domes 7 preferably have stiffening ribs 9, which are intended to increase the stability of the support domes 7.
  • As well as the receiving means 8 of the upper part 3 and the Auflagerdome 7 of the lower part can be provided with a reinforcement, which increase the stability of Auflagerdome 7.
  • an embodiment of Auflagerdome 7 made of a fiber composite material is possible and advantageous.
  • the support domes 7 are preferably arranged in a low-vibration region of the lower part 4.
  • the low-vibration area is z. B. characterized by a special rigidity and strength of the housing.
  • This particular rigidity and strength is provided, for example, by stiffening ribs 16 which extend in a vertical direction and which are arranged around the entire circumference of the edge of the lower part 4.
  • the Auflagerdome 7 are arranged only in an edge region of the lower part 4.
  • the edge region of the lower part 4 can also be provided with stiffening ribs 16.
  • the upper part 3 together with its motor capsule 5 is fastened on the upper part 4, in that the receiving devices 8 receive the support domes 7 of the lower part 4.
  • the upper part 3 is fastened with respect to the lower part 4 by means of fastening devices which extend through the receiving means 8 of the upper part 3 and which engage in the support domes 7 of the lower part 4.
  • the fastening devices 15 may be formed, for example, as screws. In this way, a very strong and at the same time very secure detachable connection between the upper part 3 and the lower part 4 results.
  • Fig. 2 shows a sectional view of the upper part 3 and the lower part 4 in the assembled state.
  • the engine capsule upper part 12 is connected to the engine capsule base 11 via a plug connection 13. It can be seen that the upper part 3 in the assembled state is spaced from the lower part 4 on all sides. Thus, no vibrations at other locations than on the support domes 7 are transmitted from the engine capsule 5 to the lower part 4.
  • the distance between the upper part 3 and the lower part 4 is at least 2 mm on all sides. This distance is usually sufficient to ensure that the upper part 3 does not touch the lower part 4 (except at the support domes) 7.
  • the motor capsule 5 is to a certain extent in a floating state in the housing 2. In this way, the noise of the vacuum cleaner is significantly suppressed.
  • the engine assembly according to the invention is not necessarily limited to the use of vacuum cleaners.
  • the motor assembly can also be used in washing machines, fully automatic coffee machines, dishwashers, grinders and the like.
  • the size and the materials used can also be adapted to different boundary conditions of the motor arrangement.
  • the housing could also be formed from a metal. It is also possible to form the complete housing from a glass fiber reinforced plastic.
  • the number and position of Trolagerdome and recording devices in the housing is to be understood only as an example and can also be varied.
