Description
Technical field
The present invention relates to a kind of pump case, a kind of pump, especially a kind of pump of the household electric appliance that are used for water guide and a kind of household electric appliance of water guide.
Background technique
At the pump that is used for carrying liquid, need be in pump chamber impeller be placed rotatablely move among, carry liquid at this by this pump chamber.This impeller can drive by motor, and the rotor bearing of this motor is on not relatively turnable axle.For described axle can being fixed with respect to pump case, this must set end upper support to this impeller in described impeller front.Preferably in one of described pump case axial suction pipe joint, carry out this fixing supporting in other words.The example of a kind of such means of fixation to the axle of pump motor in DE 103 52 487 A1 is illustrated.
In this pump case, the rotor bearing of drive motor remains in the bearing on this end in front on axle, and this bearing is fixed in the suction pipe joint of described pump case by supporting arm.Described supporting arm then radially extends on star ground round described bearing.
When pump operation, described star arrangement is in the addle stream.At this, foul can be attached on the described supporting arm such as leftovers, material fiber and other particle, can cause the cross section of suction pipe joint blocked and can cause pump to break down at last thus.
Summary of the invention
Task of the present invention thus provides a kind of scheme, utilizes this scheme can prevent that foul from stopping up and correspondingly fixing reliably the axle of the drive motor of described pump in pump case.
This task is used to have wet rotor motor the pump case of pump of (Nassl ufer-Motor) is resolved by a kind of according to a first aspect of the present invention, and this pump case has the bearing of the axle that is used for described wet rotor motor at inlet side.The salient point of this pump case is that described bearing only is fixed on the described pump case by a unique supporting arm.
By the present invention, represent that with inlet side the liquid that passes through the pump conveying of described pump case flows into the part in this pump case.Especially this part of described pump case is made of suction pipe joint.Should be received in axle in the bearing of described pump case and be the axle that the needs of described motor can not support with relatively rotating, described rotor just is bearing on this axle.By the present invention, rib or connecting sheet are called as supporting arm, the bearing that is used for the front end of described axle can be fixed on described pump case by this supporting arm.Below will be used to admit the bearing of the front end of axle to be called bearing all the time.This bearing be designed for can not relatively rotate bearing that described axle is supported.
By a unique supporting arm described bearing is fixed on the pump case, with this foul can be adhered to superincumbent acting surface and be reduced to inferior limit.In addition, in that additionally star arrangement is tightly in the zone of described bearing the time with many supporting arms, the danger that foul stops up is very big.Round described bearing, the spacing between adjacent supporting arm is very little, thereby foul is deposited in these gaps easily.
The supporting arm that is used for fixing described bearing is extending on the whole diameter of the suction pipe joint of described pump case and is being connected with described suction pipe joint on two ends, although this point is in the framework of the present invention, but only on an end, be fixed on the described pump case by the preferred described bearing of the present invention, especially be fixed in the suction pipe joint of described pump case.Described supporting arm can the radial direction from the side that is fixed along described suction pipe joint extend to the described outer radius that is arranged in the bearing on the medial axis at least always.
A kind of preferred embodiment in, described pump case has a suction pipe joint, and the length of described supporting arm is greater than the radius of described suction pipe joint.Be meant the size perpendicular to the center line of described suction pipe joint of described supporting arm as length.The numerical value that the length of preferred described supporting arm exceeds the radius of described suction pipe joint is equivalent to the outer radius of the bearing of described axle at least.Can be received in described bearing in the described supporting arm fully thus and can also improve connection between these two parts thus.In addition, the geometrical shape of the lower edge of described supporting arm can be complementary with foul this requirement that should come off on this edge in this design proposal.If it is opposite, the length of described supporting arm only is equivalent to the radius of described suction pipe joint, the slidingsurface that is used for described foul is so just determined by the external diameter of described bearing, and the external diameter of described bearing then depends on the diameter of described axle and therefore only can change with limitation.
Preferred described supporting arm so is arranged in the described suction pipe joint, makes this supporting arm vertical extent when described pump case horizontal orientation.Maximum power appears in the weight because of described motor on this direction.If described supporting arm is on this direction equally, that just can avoid shearing.Preferred described supporting arm extends to described bearing from above in this design proposal.Tension is only arranged thus in described supporting arm, and avoid fractureing of the supporting arm that on the supporting arm that vertically extends to described bearing, may occur from below.
According to a kind of mode of execution, the leading edge streamwise of described bearing and described supporting arm keeps spacing.This means that the front end of described bearing or most advanced and sophisticated leading edge of not running into described supporting arm are offset towards the direction of described pump chamber along flow direction with respect to described leading edge in other words downwards.This skew relate to described bearing the center line of described suction pipe joint in other words on the medial axis with respect to the relative position of described leading edge.As the leading edge of described supporting arm, be meant the edge towards the inlet of described suction pipe joint of described supporting arm in this respect.As the main flow direction of liquid, be meant direction from the inlet of described suction pipe joint to the pump chamber of described pump case at this.
By of the skew of described bearing, described bearing is integrated in this supporting arm with respect to the leading edge of described supporting arm.The foul that drives with flow of liquid at first contacts with described supporting arm on described leading edge, and this leading edge is a continuous edge at this, and this leading edge is especially without any projection convex shoulder in other words.This disconnection of this leading edge is present in described bearing and is in reverse to main flow direction when skew, that is to say to be present in described bearing when outstanding.Reduce foul thus attached to the danger on the described leading edge.
The leading edge of preferred described supporting arm is in one less than under 90 ° the angle with respect to the medial axis of described pump case.Medial axis as described pump case is meant center line, and the axle of pump motor is on this center line.The center line that this center line preferably is equivalent to described suction pipe joint is medial axis in other words.By the angle between described leading edge and medial axis, described supporting arm tilts towards the main flow direction of liquid.Strengthen the self-cleaning effect of described supporting arm thus.Because only be provided with a supporting arm and this supporting arm preferably end at the bearing that is used for described axle the zone, so, can make foul on the leading edge of described supporting arm, derive and thus foul is transported to the free cross-section that is not covered in the described suction pipe joint by described supporting arm by the layout of described inclination.
Angle between the medial axis of the leading edge of described supporting arm and described bearing is preferably less than 70 °.This angle allows to carry out best self-cleaning, and correspondingly is the enough supports of bearing assurance of described axle.Hereinafter will explain in detail this.
The edge of the back of preferred described supporting arm is under the angle identical with leading edge.It is identical that the width of described supporting arm keeps on its length thus basically.Described supporting arm preferably carries out rounding in below the zone on described leading edge.This means, be provided with a radius on the corner angle below the front of described supporting arm.This can also further improve the derivation of flox condition and foul.If described bearing is made as independent parts, for admitting this bearing, a recess can be set at the back side of described supporting arm so.
By the present invention, described bearing and supporting arm can be configured to one.Simplify the support of making and further improving described bearing thus.
Described supporting arm is fixed in the cross section, and this cross section is the suction pipe joint of described pump case preferably.This layout is preferred, because the diameter of described suction pipe joint is less than being attached thereto the pump chamber that connects.For described bearing being fixed on described pump case and the corresponding center line of center line suction pipe joint, it is just enough that described supporting arm has small length.In the time of in being fixed on this zone, and comparing on the inwall that is fixed on described pump chamber and the length of described supporting arm can be reduced to bottom line.
If described supporting arm tilts towards flow direction, and, produce another advantage in the described suction pipe joint in this mode from this supporting arm being fixed on so with very little length described supporting arm, that remain suction pipe joint, to be realized for the self-cleaning purpose has one such as 70 ° angle.That even described supporting arm has is less, such as only than the length of described bearing big the width of a very little numerical value, but in this position, can also guarantee, described bearing is in the immovable point below in the described suction pipe joint in the axial direction and does not have any lever arm thus, and this lever arm can cause described supporting arm to fracture or split away off from pump case.
According to another aspect, the present invention relates to a kind of pump, especially a kind of wet rotor pump that comprises by pump case of the present invention.
According to another aspect, the present invention relates to a kind of household electric appliance of water guide, these household electric appliance have at least one by pump of the present invention.Especially in household electric appliance, can't avoid foul to appear in the liquid that remains to be carried.Can preferably use in the household electric appliance of water guide by pump of the present invention, such household electric appliance are such as being washing machine, relief developing machine or similar electrical equipment.
All correspondingly be applicable to described pump and household electric appliance as long as can be applied about the described advantage of pump case and feature, vice versa.
