Definitions
- the present invention relates to a device for use in a blower arrangement, in particular for use in a blower arrangement for a household appliance, and a blower arrangement.
- the term household appliance includes Floor care appliances and extractor hoods.
- blower arrangements are used which can be set over a wide range of a respective delivery rate.
- fan arrangements with an electric motor and a centrifugal impeller connected in a rotationally fixed manner to a motor output shaft are known.
- the centrifugal fan wheel is, among other things. to form a directed air flow from one
- blower housing Surround the blower housing, which widens like a truncated cone from an inflow opening to the motor drive.
- a seal for largely filling an air gap between the centrifugal impeller and the inside of the fan housing is arranged in the inflow opening in order to reduce backflow losses and the associated loss in performance of the fan arrangement.
- This object is achieved according to the invention by a device having the features of claim 1 and a correspondingly equipped fan arrangement according to claim 14.
- a device accordingly provides that the seal is designed as a sealing ring and the sealing ring is connected out of the blower housing with a buffer part which surrounds the inflow opening in a sealing manner.
- a sealing ring is also arranged in the area of an inflow opening of the blower arrangement, which serves to seal an air gap between a centrifugal blower wheel and an inside of a blower housing.
- this sealing ring is now out of the
- Fan housing extending out and connected to a buffer part which surrounds the inflow opening as a bearing element. According to the invention there is therefore only a part which is restricted to the region of the inflow opening of the blower arrangement.
- an outer contour of the buffer part is adapted to an inner contour of an opening to be sealed.
- the buffer part thus also fulfills the tasks of fixing and sealing the blower arrangement in a predetermined opening.
- the material of the sealing ring is designed to be suitable for grinding in by a centrifugal fan wheel in an installed position on the fan housing.
- a centrifugal fan wheel in an installed position on the fan housing.
- the material of the buffer part is elastic. So it is well suited for the above-mentioned tasks of storage, fixing and sealing.
- the buffer part does not have to be applied in this form as a sealant, which hardens only on site on the blower housing.
- the buffer part is advantageously designed to be conically tapered outside the inflow opening. This makes it easier to insert the blower arrangement into a receptacle.
- the sealing ring and the buffer part are designed as a one-piece body and also in one substance. This significantly reduces manufacturing and assembly costs. Installation is also simplified, as will be described below using an exemplary embodiment with reference to the drawing. Accordingly, the one-piece combination of sealing ring and buffer part is referred to below only as a body.
- the material of the body preferably has a hardness of approximately 40 to approximately 50 Shore. Furthermore, it has a strength of approximately 10 to approximately 20 N / mm 2 and / or an elasticity of approximately 40 to approximately 60% and preferably permits an elongation of approximately 150 to approximately 300%.
- the material of the body is to be selected in particular in such a way that the above-mentioned values are maintained even after aging under the operating conditions in a floor care device with continuous vibration exposure and elevated temperatures.
- the buffer part is provided with a recess for setting an elasticity that differs from the sealing ring.
- These recesses are preferably provided in the form of approximately equidistant blind holes in the buffer part.
- a device enables. Easier inclusion of a blower arrangement even in the cramped environment and the difficult installation conditions in the interior of a floor care device. At the same time, while lowering the individual elements involved in the installation, a new seal is created between the blower housing or a blower hood and the centrifugal blower wheel while optimizing the blower performance data, in particular while reducing the losses that occur.
- the invention explained below with reference to an embodiment is particularly characterized in that no separate components are required for the inner and outer sealing. At the same time, an individually adjustable compensation is created in the production of tolerances that always occur between fixed and rotating fan parts.
- the storage and simultaneous fixation of a device according to the invention by the buffer part also achieves a substantial noise reduction. A selection of materials in a wide range of parameters is possible, in particular the proposed design measures allow a largely independent adjustment of the spring stiffness of the sealing rings and the buffer part.
- Figure 1 a sketched sectional view of a vacuum cleaner housing along a longitudinal axis
- Figure 2 shows an enlarged section of Figure 1
- Figure 3 is a sectional view of the body from the sealing ring and buffer
- Figure 4 an enlarged section of Figure 3;
- Figure 5 is a three-dimensional view of the body of Figure 3.
- FIG. 1 shows a sectional illustration along a longitudinal axis of a vacuum cleaner housing SG using a device 1 according to the invention.
- the vacuum cleaner housing SG is subdivided into a dust chamber SK following an sucked-in air flow L, which is separated from an engine room MR by a partition wall TW with one or more filters F.
- An air guide funnel LT is provided in the partition TW as a space-saving and flow-optimized adaptation of the air flow L for transfer to a fan G.
- FIG. 2 An enlarged area of FIG. 2 shows an area around an engine M in the engine compartment MR.
- Arrows P1 and P2 identify two bearing points of the engine M in the engine compartment MR or in the air guide funnel LT of the partition TW and an opposite rear wall of the engine compartment MR.
- the shape of a device according to the invention or a body 1, which serves as one of the two bearing points, can now also be seen in section.
- the body 1 is clamped in the area of an inflow opening E on an edge area of a blower housing GG.
- the body 1 forms a sealing ring 2 in the inflow opening E.
- the body then extends out of the inflow opening E and radially surrounds the inflow opening E with the formation of a buffer part 3.
- the body 1 is thus closed towards the dust chamber and on an outer circumference U one
- the fan with the motor M fixedly mounted thereon is arranged sealingly with the air guide funnel LT and thus on the partition wall TW towards the dust chamber SR.
- the body 1 shown in the figures of the drawing also serves as a sealing ring 2 or as a seal between the blower housing GG and the centrifugal fan wheel LR and also as a sealing bearing of the blower housing GG on the partition wall TW.
- the buffer part 3 serves to compensate for tolerances and also reduces the noise that occurs during operation. In addition, vibrations and a tendency to oscillate in the arrangement of the fan G and the motor M are reduced by coordinating a spring stiffness of the material in the region of the buffer part 3.
- a radially extending recess 4 is provided in the inflow opening E.
