Description

La présente invention concerne un dispositif pour le nettoyage du condensateur d'un appareil ou d'une installation frigorifique ou de conditionnement.The present invention relates to a device for cleaning the condenser of a refrigeration or conditioning appliance or installation.

Il est connu que les radiateurs des échangeurs de chaleur, les appareils ou installations frigorifiques ou congélateurs, aussi bien domestiques qu'industriels, comprenent un condensateur du fluide réfrigérant qui s'étend dans un plan vertical, auquel est associé un aspirateur de l'air ambiant, placé en aval de celui-ci, de manière à ce que l'air aspiré frappe frontalement le serpentin et les ailettes du condensateur, ce qui est nécessaire pour l'élimination de la chaleur produite par le compresseur.It is known that radiators for heat exchangers, refrigeration or freezer apparatus or installations, both domestic and industrial, include a condenser of the refrigerant which extends in a vertical plane, with which is associated an air vacuum cleaner. ambient, placed downstream of it, so that the sucked air strikes the coil and the fins of the condenser frontally, which is necessary for the elimination of the heat produced by the compressor.

Au fur et à mesure, la poussière entra née par l'air aspiré se dépose en s'accumulant dans les interstices entre lesdites ailettes jusqu'à les boucher complètement, ce qui provoque l'augmentation de pression du fluide réfrigérant en entra nant le surchauffage du compresseur qui, à court terme, est mis hors d'usage. Cette condition provoque l'arrêt du réfrigérateur ou de l'installation de conditionnement avec un dommage évident, également économique, surtout en raison de la détérioration des produits conservés, comme c'est le cas des produits alimentaires et pharmaceutiques.As and when, the dust entered by the sucked air is deposited by accumulating in the interstices between the said fins until completely blocking them, which causes the pressure of the coolant to increase, causing the overheating. of the compressor which, in the short term, is put out of use. This condition will cause the refrigerator or the packaging plant with obvious damage, also economical, especially due to the deterioration of the preserved products, as is the case with food and pharmaceutical products.

La présente invention a pour but d'éliminer les inconvénients précités.The present invention aims to eliminate the aforementioned drawbacks.

Ce résultat a été atteint conformément à l'invention en adoptant l'idée d'enlever périodiquement la poussière qui se dépose entre les ailettes et sur le serpentin du condensateur d'un réfrigérateur ou d'une installation de conditionnement, en utilisant au moins une brosse montée sur un support coulissant le long de deux guides verticaux, s'étendant horizontalement sur toute la longueur du condensateur et dont les poils sont capables d'atteindre le serpentin; et des moyens pour le déplacement du support de ladite brosse avec un mouvement alternatif vertical.This result has been achieved in accordance with the invention by adopting the idea of periodically removing the dust which is deposited between the fins and on the condenser coil of a refrigerator or of a conditioning installation, using at least one brush mounted on a support sliding along two vertical guides, extending horizontally over the entire length of the capacitor and the bristles of which are capable of reaching the coil; and means for moving the support of said brush with a vertical reciprocating movement.

Etant donné que l'opération de brossage n'est nécessaire que de temps à autre, selon une forme de réalisation simplifiée, les moyens de déplacement du support de la brosse sont constitués par un levier à main, articulé sur un des guides verticaux ou, en alternative, par une poignée fixée directement à l'extrémité du support de la brosse.Since the brushing operation is only necessary from time to time, according to a simplified embodiment, the means for moving the support of the brush are constituted by a hand lever, articulated on one of the vertical guides or, alternatively, by a handle fixed directly to the end of the brush holder.

Avantageusement, pour réaliser un dispositif automatique et dans tous les cas où le condensateur ou le radiateur se trouve dans une position non facilement accessible, les moyens de déplacement de la/les brosse/s sont constitués par un mécanisme à manivelle et bielle oscillante, avec une manivelle montée sur l'arbre d'un moteur électrique et une bielle articulée respectivement sur la manivelle et sur le support de la ou des brosses.Advantageously, to produce an automatic device and in all cases where the capacitor or the radiator is in a position that is not easily accessible, the means for moving the brush (es) consist of a crank mechanism and an oscillating rod, with a crank mounted on the shaft of an electric motor and a connecting rod articulated respectively on the crank and on the support of the brush or brushes.

Avantageusement, ledit moteur électrique est commandé par une minuterie ou par un thermostat, pour effectuer, de manière automatique, une ou plusieurs course de nettoyage du condensateur ou similaire avec une fréquence prédéterminée; plus simplement le moteur électrique peut être commandé au moyen d'un bouton-poussoir.Advantageously, said electric motor is controlled by a timer or by a thermostat, to carry out, automatically, one or more cleaning strokes of the capacitor or the like with a predetermined frequency; more simply the electric motor can be controlled by means of a push button.

La solution proposée par la présente invention permet d'effectuer facilement et de manière sûre le nettoyage du condensateur ou du radiateur de n'importe quel appareil ou installation frigorifique, de conditionnement ou similaire, même automatiquement, avec un coût réduit et largement compensé par un fonctionnement plus sûr et fiable pour de longues périodes sans interruption.
