Definitions
- the invention relates to a vacuum cleaner according to the preamble of claim 1.
- a vacuum cleaner with a blower unit which is surrounded by an inner housing capsule, which in turn is installed in an outer housing capsule while leaving a flow space, between which and the housing there is a free space.
- the air flow generated by the blower unit is guided through the flow space to an outlet provided on the housing.
- the blower unit is completely encapsulated by means of an inner cup-shaped housing capsule and an outer housing capsule surrounding it, which consists of two cup-shaped housing shells.
- the inner housing capsule is held in the outer housing capsule by means of profiled rails molded onto an outer wall of the inner housing capsule.
- the disadvantage of this holder is that the inner housing capsule must be attached to the outer housing capsule in a separate assembly step. This construction not only requires an additional assembly step, but the flow channel cannot be largely smooth-walled either, since the existing assembly gaps form interfering edges for the air flow.
- this object is achieved in that at least one capsule part of an insulating capsule is connected in one piece to a housing part, in particular the blower housing. Due to the one-piece connection of the capsule part or insulating capsule and the housing part or blower cover, the flow channel is designed to be more flow-compatible, in particular since there are fewer assembly gaps and therefore fewer interfering edges are located in the flow channel. Installation errors are reliably excluded because the exhaust air duct is precisely fixed and therefore no installation errors can occur.
- the assembly itself is simplified since a separate assembly step for attaching a separate capsule part is no longer required.
- the geometry of the flow channel can be determined in a particularly streamlined manner regardless of the otherwise required assembly and connection means.
- a first capsule part is molded onto the housing, in particular onto a lower shell of the vacuum cleaner. If a lower capsule part is already molded onto the lower shell of the vacuum cleaner housing, the motor / blower unit can be inserted into the lower shell in a simple manner, without a capsule part having to be mounted on the motor / blower unit beforehand and without this preassembled unit separately Need to attach the vacuum cleaner housing.
- the variety of parts is also reduced if the insulating capsule or capsule parts thereof and / or the blower housing or housing parts, e.g. the blower cover is formed directly on a part of the vacuum cleaner housing, preferably on the lower shell of the vacuum cleaner. This molding of the parts can be carried out favorably in the plastic injection molding process.
- the first capsule part can advantageously have capsule wall sections extending inwards from the lower shell. Due to the inward-facing capsule wall sections, the motor / blower unit can be easily and quickly inserted vertically from above into the lower shell, which means that assembly can be carried out very quickly. At the same time, the motor / blower unit is already soundproofed from below and from the side walls of the capsule part. This enclosing of the motor / blower unit, which already takes place on five side walls, is achieved without assembly gaps and thus without the use of additional sealants. Possibly. separate gaps through which sound could penetrate to the outside are largely avoided, so that particularly good sound insulation is achieved.
- At least one capsule wall section can preferably have an opening which connects an interior space delimited by the insulating capsule to the flow channel.
- the overflow connection from the interior of the insulating capsule and the flow channel is already integrally formed during the production, in particular by injection molding, so that no additional flow channel connections or similar connecting pieces have to be used separately and connected to the flow channel in terms of flow technology.
- the sealing problem is also eliminated.
- the housing part of the blower housing can be formed by a housing half, in particular by the lower shell of the vacuum cleaner. It is particularly advantageous if not only capsule parts of the insulating capsule, but also housing parts, such as, for example, the blower housing, are formed or molded directly on the lower shell or, alternatively, another housing part of the vacuum cleaner. The number of parts is also reduced and the necessary separation gaps between individual housing parts are reduced. The sealing effort is less. If additional seals can be omitted, the vacuum cleaner can be manufactured more cheaply.
- the housing part of the blower housing has a holder for receiving a bearing element for the motor / blower unit.
- holders for the motor / blower unit can already be formed or molded onto a component of the vacuum cleaner. It will preferably be the blower housing, but the holder (s) for the motor / blower unit can also be e.g. be attached or molded directly on the lower shell or on a capsule part of the insulating capsule. The holder or a part of the holder can also be arranged on a dividing wall running between a dust seam melting chamber and a blower chamber.
- the holder is preferably designed as a half-shell-shaped, open upwardly projecting shoulder protruding into the blower chamber. This enables the motor / blower unit to be inserted quickly and easily into the vacuum cleaner during manufacture, since it is sufficient to insert the motor / blower unit only into the housing part from above until the motor / blower unit rests on the half-shell-shaped holder. This considerably simplifies assembly.
- the housing part of the blower housing is a blower chamber cover, on which a second capsule part of the insulating capsule is molded.
- the parts of the insulating capsule or blower housing which are preferably molded onto the lower shell of the vacuum cleaner, it is advantageous to provide only a single further component in order to store the motor / blower unit in an insulating capsule in a blower chamber within the vacuum cleaner housing in a sound-insulated manner. Then the variety of parts is on limited to the bare minimum. There is then only a single parting plane, but this is necessary in order to be able to insert the motor / blower unit into the cavity formed. There remains only a single separating gap to be sealed between these two components.
- a main flow channel for a main air flow is arranged running between the blower chamber cover and the second capsule part.
- the main flow channel can be arranged running behind an end of the motor / blower unit opposite an intake opening.
- At least one secondary flow channel for a secondary air flow can be arranged running between the blower chamber cover and the second capsule part. Due to the location of the main flow channel, the main air flow can be fed centrally to the motor / blower unit in the direction of the blow-out opening. If several secondary flow channels are provided, these can be connected to the main flow channel in the same length. The same length of the bypass flow channels ensures that the swirling effect at each intersection of the bypass air flow and the main air flow is at least approximately the same.
- a particularly effective swirling is achieved by crossing the flow directions of the secondary air flow and the main air flow.
- the crossing is preferably carried out by vertically colliding air streams.
- the secondary air flow and main air flow can, however, also cross at a different angle to one another, for example either at an acute angle to one another or even at an obtuse angle to one another.
- the secondary air flow and main air flow could even be directed towards one another.
- At least one bypass duct is arranged to run laterally of the motor / blower unit.
- Two bypass channels are preferably provided, which are arranged to run on opposite sides of the motor / blower unit.
- a plurality of bypass ducts, each in pairs to be arranged running on opposite sides of the motor / blower unit, which preferably open into a common main flow duct.
- the secondary flow channels preferably have a rectangular cross section and extend essentially vertically. This arrangement results in a good draft in the secondary flow channels and the housing part of the vacuum cleaner which has the secondary flow channels is nevertheless simple and inexpensive to produce.
- at least one secondary flow channel is thus connected to the main flow channel in terms of flow technology via at least one inflow opening.
- the inflow opening can be designed as a circular bore in a thin intermediate wall between the secondary flow channel and the main flow channel. This creates a sharp-edged orifice in the area of the inflow opening, on which there is an additional swirling of the exhaust air flow.
- the free opening cross section of the inflow opening can preferably be smaller than the flow cross section in the rest of the secondary flow channel.
- the opening cross section of the at least one inflow opening is smaller than the flow cross section of the respective secondary flow channel. This results in a constriction of the flow cross-section in the transition area of the secondary flow channel into the main flow channel.
- a throttle point can also be designed in the manner of a Venturi nozzle.
- a plurality of in particular two inflow openings can be provided in each side flow channel. The sum of the opening cross sections of the two or more inflow openings should nevertheless be smaller than the flow cross section in the rest of the secondary flow channel.
- the capsule wall sections of the first capsule part and the capsule wall sections of the second capsule part are preferably arranged to overlap. Due to the overlap, a guide between the first and second capsule part is already created during assembly, so that the two capsule parts can be assembled in the correct position quickly and easily.
- the overlapping areas of the two capsule parts also form a labyrinth-like gap seal, so that a certain sealing effect has already been achieved without having to apply a separate sealant.
- a seal can be arranged between the overlapping capsule wall sections.
- an upper edge of a housing part of the blower housing molded onto the lower shell can form a sealing arrangement with a lower edge of a blower housing cover.
- the seal arrangement can be a labyrinth seal, one molded onto one of the edges Sealing lip or a sealing cord that is inserted into a groove that is formed on one of the edges.
- additional components of the vacuum cleaner can also be integrally formed on a part of the insulating capsule or the blower housing, as required.
- a receptacle for the exhaust air filter, a holder for a cable drum, a cable running area or a receptacle for a spindle of a slider can be formed directly on a housing part, in particular on the blower cover.
- fiber-containing damping inserts can preferably be inserted at every point of the flow channel.
