Abstract
A peristaltic pump (1) with a rotating squeeze roller carrier (12), a squeeze hose (14) partly looping around the squeeze rollers (13) and a curved contact wall (19) for the squeeze hose (14), the contact wall (19) being opposite to the effective surface of the squeeze rollers, whereby the contact wall (19) is movable by way of a setting lever (5) from a setting (FIG. 5), which enables fitting with the squeeze hose (14), to a work setting (FIG. 6), pressing the squeeze hose (14) against the squeeze rollers (13) and whereby the contact wall (19) forms a part of a pump housing cover (6) at which the setting lever (5) is positioned to be outwardly pivotable for displacement of the cover (6).
Description
- The invention relates to a peristaltic pump, in particular for use in dishwashers for the metering of a liquid or pasty cleaning agent, with a rotating squeeze roller carrier, a squeeze hose partly looping round the squeeze rollers and a curved contact wall, which is disposed opposite the effective surface of the squeeze rollers, for the squeeze hose.
- In one metering pump used by the applicant the squeeze hose is laid in a block-shaped pump body, which has a substantially semicircular edge wall, around spring-mounted squeeze rollers on a squeeze roller carrier, wherein after assembly a cover is screw-connected over this configuration, one of the counter-bearings of the squeeze roller carrier being provided in the cover. In that case it is also known to provide the squeeze hose bend, which is positioned in the pump, with coupling and detent heads which are fixed in the region of the housing outer wall in order to then connect the hoses with, for example, the dishwasher.
- In the case of another solution employed by the applicant (e.g. DE 39 4 3 430 A1) the squeeze hose bend is accommodated in a plastics material yoke which forms the curved contact wall for the squeeze hose in the use position, wherein the curved wall is detented with a squeeze hose, which is detented in place, after being laid around the squeeze hose rollers at the pump body. The fastening of the squeeze wall in a plane, perpendicular to the squeeze -roller axis, is also shown in DE-26 57 908-B2 or DD-157 620, whereas U.S. Pat. No. 4,256,442 shows the fasting of the wall through a parallel leverage with a pivot handle.
- It has proved that the known designs of peristaltic pumps are still comparatively costly, wherein in the case of the first solution the exchange, which is necessary from time to time, of the squeeze hose bend is possible only by screwing on the cover, whereas in the case of the solution provided with the pivot cover a disadvantage arises, in particular, in the susceptibility of the cover to breakage and thus loss of the functional capability of the pump.
- Peristaltic pumps of-other construction are known from DE 33 26 766-A1 or DE-696 16 336 T2 or from DE-GM 71 47 400, to give only a few examples.
- The object of the invention is to create a solution by which a simple exchange of the squeeze hose bend is made possible, without loosening any screws, and with a robust construction of all elements.
- According to the invention this object is met with a peristaltic pump according to
claim 1. - Because of the design of the contact wall movable by way of a pivot lever an extremely simple squeeze hose positioning is possible. The pivot lever is opened, wherein the contact wall is removed from the hose, the hose can be removed or exchanged, the pivot lever is closed and the contact wall and all other pump elements are disposed in the working position. At the same time it is achieved by this design that on closing the pump housing cover the contact wall, which is integrally formed therewith, is simultaneously displaced into the working position.
- Embodiments of the invention are evident from the subclaims.
- According to the invention the squeeze roller carrier together with the squeeze rollers is positioned at a housing base, wherein support detents for receiving pivot cams of the setting lever are provided at the housing base. In that case it can be advantageous in a further embodiment if guides for receiving slide rails at the housing cover are provided at the housing base.
- It can be advantageous if an end wall with a detent tongue as well as with two substantially U-shaped recesses for passage of the squeeze hose is provided at the housing base, wherein in a further embodiment it can be provided that the setting lever is constructed as a yoke with counter-detent for detenting at the detent tongue in the housing closed setting. In that case it is possible to provide with the same detent element a carrier not only for the squeeze hose bend, but also for the setting lever or setting yoke.
- The squeeze hose can be provided at a hose carrier or, however, can be positioned as an individual element in corresponding detent recesses in the housing end wall, which is equally proposed by the invention.
- Further advantages, details and features of the invention are evident from the following description as well as on the basis of the drawing, in which:
- FIGS. 1 to 4 show, in perspective illustration, different positions of the pump head of the peristaltic pump from the unlocked setting up to the squeeze hose withdrawal setting and
-
FIGS. 5 and 6 show a cross-section through the housing of the pump head in unlocked and locking setting. - Of the peristaltic pump according to the invention, there is illustrated in the figures the pump head; the corresponding drives are not further depicted here.
- The pump head denoted generally by 1 comprises a
base element 2 whith an integrally formedend wall 3 and twoside walls 4 which are in turn integrally formed therewith, as well as ahousing cover 6 which is displaceable by way of apivot lever 5, and which in turn has integrally formedside wall surfaces 7 parallel to theside wall surfaces 4 of the base part. Theside wall surfaces 7 of the housing cover have, at the lower outer edge thereof, integrally formedslide rails 8 which are displaceable guided in corresponding counter rails or grooves in the region of transition from the base of theside wall surfaces 4. - As evident particularly from
FIG. 2 , thepivot yoke 5 is pivotably mounted at thecover 6 by way of inwardly pointinghinge pins 9, wherein outwardly pointingpins 10 can bear againstpivot projections 11 which are integrally formed at theside walls 4 of the base part to pint inwardly. - A rotor 12 (
FIG. 4 ) with threesqueeze rollers 13, which 6 can be brought into rotation by a drive which is not illustrated in more detail, is detented in thebase element 2. As illustrated inFIGS. 3 and 4 , asqueeze hose bend 14 is fixed by thecoupling projections 15 in asqueeze hose carrier 16, which can be detented—with or released from thefront side 3 by way of sliding guides, wherein theconnections 15 project outwardly beyond the entire housing. - At this point it is to be noted that the
squeeze hose bend 14 is fixable also as an individual element by way of alternatively providedslots 17 in thecarrier plate 16 or directly in theslots 18 in theend wall 3, depending on the respective construction. Thecover 6 has, in the interior, thecontact wall 19 for thesqueeze hose 14, wherein thiscontact wall 19 presses thesqueeze hose 14 against thesqueeze roller 13 by way of pivotation in accordance witharrow 20 inFIG. 5 , as is evident fromFIG. 6 , which shows the pump head in closed setting, i.e. thecover 6 is displaced in accordance witharrow 21 from the position illustrated inFIG. 5 to the closed position illustrated inFIG. 6 . - The
end wall 3 is beyond that furnished with adetent element 22 which co-operates with adetent counter-element 23 at thepivot yoke 5 and detents all elements together in the closed setting. - It can be seen that an exchange of the
squeeze hose bend 14 subjected to wear is extremely simple: - From the closed setting illustrated in
FIG. 6 , thepivot lever 5 is pivoted upwardly, whereby solely through the resilience of thesqueeze hose 14, which bears against thecontact wall 19, thecover 6 is displaced to the right in the figures, at least into the slightly open position illustrated inFIG. 1 . If the pivot lever is now pivoted somewhat further and releases thecontact cam 11, the cover can be withdrawn from thehousing base 3 by way of theslide rails 8, this position being illustrated inFIG. 3 , wherein at the same time thesqueeze hose bend 14 is freed so that thesqueeze hose carrier 16 together with thesqueeze hose 14 can be withdrawn upwardly, as is depicted inFIG. 4 . After placing a newsqueeze hose bend 14 around thesqueeze rollers 13, there takes place a pushing together of the elements and finally locking in the working position illustrated inFIG. 6 .
