Description Description

[0001] La présente invention se rapporte à une pompe monobloc pour l'évacuation de liquide de condensation, et plus particulièrement à une pompe monobloc comportant une pompe, un dispositif de détection de niveau et un circuit électrique. The present invention relates to a monobloc pump for the discharge of condensation liquid, and more particularly to a monobloc pump comprising a pump, a level detection device and an electrical circuit.

[0002] Les pompes d'évacuation de liquide de condensation sont utilisées dans les groupes de production de froid, les climatiseurs par exemple. Dans la plupart des cas les groupes de production de froid destinés à être posés le sol ou fixés ou montés sur ou dans un mur doivent être de faible encombrement et par conséquent les pompes doivent être aussi petite que possible. Condensate discharge pumps are used in cold production units, air conditioners for example. In most cases the cold production units intended to be laid on the ground or fixed or mounted on or in a wall must be small in size and therefore the pumps must be as small as possible.

Les formes d'exécutions connues présentent des inconvénients Known embodiments have disadvantages

[0003] En effet les formes d'exécutions connues sont toutes réalisées avec des éléments séparés, par exemple une pompe avec son circuit électrique et séparément un détecteur de niveau de liquide de condensation. Ces formes d'exécutions présentent l'inconvénient essentiel d'être encombrantes. De plus, par le fait que les pompes fonctionnent à des fréquences relativement élevées, les pompes d'évacuation à éléments séparés présentent l'inconvénient d'être bruyantes. Indeed the known embodiments are all made with separate elements, for example a pump with its electrical circuit and separately a liquid level sensor condensation. These forms of execution have the essential disadvantage of being bulky. In addition, because the pumps operate at relatively high frequencies, the separate element discharge pumps have the disadvantage of being noisy.

[0004] Le but de la présente invention consiste donc à remédier aux formes d'exécutions connues. The object of the present invention is therefore to remedy known forms of execution.

[0005] Le but est atteint selon les principes de l'invention définis par la revendication 1. The object is achieved according to the principles of the invention defined by claim 1.

[0006] La pompe monobloc pour l'évacuation de liquide de condensation comporte un tube transparent dans lequel est monté une pompe munie d'un piston avec un circuit électrique et un dispositif de détection comportant un réservoir qui récupère le liquide de condensation. Un embout d'entrée de liquide est monté a une des extrémités du tube transparent et un conduit de sortie de liquide est monté à l'autre extrémité. Lorsque du liquide arrive par l'embout d'entrée, le liquide agit sur le détecteur de niveau qui actionne la pompe. L'avantage essentiel de la pompe monobloc est son faible encombrement du également au fait que la pompe monobloc présente une forme de cylindre. Un autre avantage important est du au fait que la pompe monobloc permet d'obtenir, selon la matière utilisée pour la réalisation du tube transparent, un très bon amortissement des bruits et en conséquence permet d'obtenir une pompe monobloc silencieuse. Le fait que le tube soit transparent permet un contrôle efficace du fonctionnement de la pompe monobloc. The monobloc pump for the discharge of condensation liquid comprises a transparent tube in which is mounted a pump provided with a piston with an electric circuit and a detection device comprising a reservoir which recovers the condensation liquid. A liquid inlet tip is mounted at one end of the transparent tube and a liquid outlet conduit is mounted at the other end. When liquid arrives through the inlet nozzle, the liquid acts on the level sensor that actuates the pump. The essential advantage of the monobloc pump is its small size also due to the fact that the monobloc pump has a cylinder shape. Another important advantage is that the one-piece pump makes it possible, according to the material used for the production of the transparent tube, to have a very good damping of the noises and consequently makes it possible to obtain a silent one-piece pump. The fact that the tube is transparent allows effective control of the operation of the monobloc pump.

[0007] La figure annexée démontre schématiquement et à titre d'exemple les principes de l'invention. The attached figure shows schematically and by way of example the principles of the invention.

[0008] La fig. 1 est une vue en coupe longitudinale d'une pompe monobloc. FIG. 1 is a longitudinal sectional view of a monoblock pump.

[0009] En référence à la fig. 1, un embout d'entrée 1 est monté à l'une des extrémités d'un tube transparent 7 et maintenu par un joint d'étanchéité. L'embout d'entrée 1 comporte un conduit d'évacuation 2. Un support 4 est monté dans le tube transparent 7 et maintenu par un joint de l'extrémité arrière du tube transparent 7. Une pompe comporte un orifice d'aspiration un joint de d'étanchéité souple 19, un ressort 18, une chambre d'aspiration 17 une soupape de piston 16, une soupape de refoulement 15, un conduit de refoulement 14. Une chambre 13 est prévue dans la pompe. Cette chambre est disposée de manière à ce que du liquide ne puisse pas y entrer. Un piston 9 est soumis à l'action d'une bobine 8 qui est reliée à un circuit électronique 10. La bobine 8 est alimentée par le courant alternatif. Le circuit électronique est alimenté par un cordon d'alimentation 12. Un réservoir d'entrée 23 est pratiqué dans la partie avant de la pompe monobloc. Un flotteur 21 est monté coulissant sur un support tubulaire 22. Le support tubulaire 22 comporte trois interrupteurs magnétiques qui commandent I'actionnement de la pompe, une position fermée lorsqu'il n'y a pas de liquide, une position ouverte lorsqu'il y a du liquide à pomper, et une position d'alarme en cas d'une surcharge de liquide dans le réservoir. La position d'alarme fonctionne soit quand il y a une trop grosse quantité d'arrivée de liquide, soit en cas de non fonctionnement de la pompe. [0009] Referring to FIG. 1, an inlet nozzle 1 is mounted at one end of a transparent tube 7 and held by a seal. The inlet nozzle 1 comprises a discharge conduit 2. A support 4 is mounted in the transparent tube 7 and held by a seal of the rear end of the transparent tube 7. A pump comprises a suction port a seal flexible sealing member 19, a spring 18, a suction chamber 17 a piston valve 16, a discharge valve 15, a discharge pipe 14. A chamber 13 is provided in the pump. This chamber is arranged so that liquid can not enter. A piston 9 is subjected to the action of a coil 8 which is connected to an electronic circuit 10. The coil 8 is powered by the alternating current. The electronic circuit is powered by a power cord 12. An inlet reservoir 23 is formed in the front part of the monoblock pump. A float 21 is slidably mounted on a tubular support 22. The tubular support 22 comprises three magnetic switches that control the operation of the pump, a closed position when there is no liquid, an open position when there has liquid to pump, and an alarm position in case of a liquid overload in the tank. The alarm position works either when there is too much liquid supply or when the pump is not running.

[0010] Dans la pratique, le liquide de condensation arrive par l'embout d'entrée 1, s'introduit dans le réservoir d'entrée 23 et dès que le flotteur atteint un certain niveau, la pompe est enclenchée et le liquide est évacué par l'embout de sortie et s'écoule dans le conduit de sortie et ensuite dans les égouts. In practice, the condensation liquid arrives through the inlet nozzle 1, is introduced into the inlet reservoir 23 and as soon as the float reaches a certain level, the pump is engaged and the liquid is discharged. through the outlet nozzle and flows into the outlet duct and then into the sewers.

[0011] Le joint d'étanchéité 19 est réalisé dans une matière très élastique de manière à compenser les vibrations provoquées par l'oscillation du piston et par conséquent aussi à réduire les bruits de fonctionnement. The seal 19 is made of a highly elastic material so as to compensate for the vibrations caused by the oscillation of the piston and therefore also to reduce the operating noise.

[0012] Le descriptif mentionne un tube transparent. Le tube peut également être réalisé dans un matériau non transparent. The description mentions a transparent tube. The tube may also be made of a non-transparent material.

[0013] Le descriptif mentionne un tube. Une section ovale, carrée, rectangulaire, par exemple, peuvent aussi être utilisées selon la place à disposition pour l'installation de la pompe. The description mentions a tube. An oval, square, rectangular section, for example, can also be used depending on the space available for the installation of the pump.

[0014] Le dessin montre une pompe à piston. Le principe monobloc permet également l'utilisation d'autres types de pompes. The drawing shows a piston pump. The monobloc principle also allows the use of other types of pumps.
