Description

Dispositif de relevage de condensats comprenant une cuve de réception des condensats mobile, ou montée sur un support mobile, en translation et/ou rotation Condensate lifting device comprising a mobile condensate receiving tank, or mounted on a mobile support, in translation and / or rotation
1. Domaine 1. Domain
Le domaine de l'invention est celui des dispositifs de relevage de condensats, destinés à être mis en œuvre dans des systèmes produisant des condensats, notamment des systèmes de climatisation, des systèmes de réfrigération, des systèmes de ventilation ou des systèmes de chauffage.  The field of the invention is that of condensate lifting devices, intended for use in systems producing condensates, in particular air conditioning systems, refrigeration systems, ventilation systems or heating systems.
2. Art antérieur 2. Prior art
Dans ce qui suit, on s'attache plus particulièrement à décrire la problématique existant dans le domaine des systèmes de climatisation, à laquelle ont été confrontés les inventeurs de la présente demande de brevet.  In what follows, we focus more particularly on describing the problem existing in the field of air conditioning systems, which the inventors of this patent application were confronted with.
Toutefois, l'invention ne se limite pas à ce domaine particulier d'application mais s'applique à tous les systèmes produisant des condensats, notamment les systèmes de type « HVAR » (pour « Heating, Ventilation, Air-conditionning, Réfrigération » en anglais, soit « Chauffage, ventilation, air conditionné et/ou réfrigération »).  However, the invention is not limited to this particular field of application but applies to all systems producing condensates, in particular systems of the "HVAR" type (for "Heating, Ventilation, Air-conditioning, Refrigeration" in English, ie "Heating, ventilation, air conditioning and / or refrigeration").
Dans un système de climatisation, les condensats - qui résultent de la condensation de la vapeur d'eau présente dans l'air ambiant que l'on refroidit - sont classiquement récupérés dans un réservoir, ou plus généralement dans une cuve de récupération, qui peut être dans certains cas un simple panneau de collecte.  In an air conditioning system, the condensates - which result from the condensation of water vapor present in the ambient air which is cooled - are conventionally recovered in a tank, or more generally in a recovery tank, which can in some cases be a simple collection sign.
Il est nécessaire d'évacuer les condensats récupérés, d'une part pour éviter le débordement de la cuve de récupération et d'autre part pour limiter les risques de contamination bactérienne liée à la stagnation des condensats dans cette cuve.  It is necessary to evacuate the recovered condensates, on the one hand to avoid overflow of the recovery tank and on the other hand to limit the risks of bacterial contamination linked to the stagnation of the condensates in this tank.
Ceci peut se faire par gravité, par exemple à l'aide d'un tuyau rigide ou semi-rigide relié à un système d'évacuation des eaux usées, ou par pompage des condensats recueillis dans la cuve de récupération.  This can be done by gravity, for example using a rigid or semi-rigid pipe connected to a waste water evacuation system, or by pumping the condensates collected in the recovery tank.
L'invention s'applique plus particulièrement à ce dernier cas.  The invention applies more particularly to the latter case.
Les systèmes de relevage de condensats par pompage mettent généralement en œuvre une pompe hydraulique pilotée - c'est-à-dire mise en route et arrêtée - par des moyens de détection du niveau des condensats présents dans la cuve. Pumping condensate systems generally provide operates a hydraulic pump controlled - that is to say, started and stopped - by means of detecting the level of condensate present in the tank.
Ces moyens de détection du niveau des condensats peuvent reposer sur un capteur de niveau, par exemple un capteur capacitif, configuré pour pouvoir mesurer au moins deux niveaux de condensats à l'intérieur du réservoir, correspondant à un premier niveau maximum, auquel la pompe doit être activée afin d'évacuer les condensats, et un second niveau minimum, auquel la pompe doit être arrêtée.  These means for detecting the level of condensate can be based on a level sensor, for example a capacitive sensor, configured to be able to measure at least two levels of condensate inside the tank, corresponding to a first maximum level, at which the pump must be activated in order to evacuate the condensates, and a second minimum level, at which the pump must be stopped.
Un troisième niveau de condensats, dit de sécurité, peut être mesuré, supérieur au niveau maximum, et correspondant à une situation critique, dans laquelle la hauteur de liquide est anormalement élevée (par exemple du fait d'une pompe bouchée ou hors d'usage).  A third level of condensate, called safety, can be measured, higher than the maximum level, and corresponding to a critical situation, in which the liquid height is abnormally high (for example due to a blocked or out of use pump). ).
Des moyens de traitement délivrent à la pompe les commandes requises (mise en route ou arrêt), en fonction des niveaux de condensats détectés par les moyens de détection du niveau des condensats.  Processing means deliver the required commands to the pump (start or stop), as a function of the condensate levels detected by the condensate level detection means.
Un système d'alarme peut aussi être prévu de façon à avertir l'utilisateur d'un niveau de liquide anormalement haut dans la cuve de réception, notamment lorsque le niveau de sécurité est atteint.  An alarm system can also be provided so as to warn the user of an abnormally high level of liquid in the receiving tank, in particular when the security level is reached.
Les dispositifs de relevage de condensats comprennent ainsi un certain nombre de composants essentiels, que le technicien affecté à l'installation du dispositif doit mettre en place un à un, puis raccorder par une pluralité de câbles et conduits.  The condensate lifting devices thus comprise a certain number of essential components, which the technician assigned to the installation of the device must install one by one, then connect by a plurality of cables and conduits.
En d'autres termes, les composants du dispositif de relevage de condensats sont fournis puis mis en place de manière séparée, ou indépendamment les uns des autres, ce qui implique l'utilisation d'un nombre relativement élevé d'éléments de connectique (hydraulique et électrique), de possibles difficultés d'installation, et des risques de disfonctionnement, de perte de temps et d'argent,...  In other words, the components of the condensate lifting device are supplied and then installed separately, or independently of each other, which implies the use of a relatively large number of connection elements (hydraulic and electrical), possible installation difficulties, and risks of malfunction, loss of time and money, ...
De plus, il peut être difficile pour le technicien d'installer certains de ces composants, qui doivent occuper une position spécifique au sein du système de climatisation, dans des zones parfois difficiles d'accès.  In addition, it may be difficult for the technician to install some of these components, which must occupy a specific position within the air conditioning system, in areas that are sometimes difficult to access.
C'est par exemple le cas des moyens de détection des niveaux de condensais qui doivent généralement être placés dans ou auprès de la cuve, ou de la pompe de relevage qui doit généralement être installée à l'intérieur d'une goulotte ou d'un élément d'architecture intérieure, comme un faux plafond. This is for example the case of means for detecting the levels of condensate which generally have to be placed in or near the tank, or the lifting pump. which must generally be installed inside a trunking or an element of interior architecture, such as a false ceiling.
Dans ces systèmes, la pompe de relevage de condensats doit être raccordée au climatiseur par le biais de plusieurs câbles électriques, notamment un câble correspondant à la phase, un câble correspondant au neutre, et un câble d'alarme, correspondant au niveau de sécurité.  In these systems, the condensate pump must be connected to the air conditioner by means of several electric cables, in particular a cable corresponding to the phase, a cable corresponding to neutral, and an alarm cable, corresponding to the security level.
Le câble d'alarme pose parfois des difficultés d'installation aux techniciens : en effet, il peut être peu aisé de relier celui-ci à un climatiseur qui n'a pas été conçu explicitement pour coopérer avec le dispositif de relevage considéré.  The alarm cable sometimes poses installation difficulties for technicians: in fact, it can be difficult to connect it to an air conditioner which has not been explicitly designed to cooperate with the lifting device considered.
Une mauvaise installation du système d'alarme est cependant préjudiciable au bon fonctionnement du dispositif de relevage de condensats, puisqu'il existe alors un risque qu'un niveau anormalement haut de condensats dans la cuve soit détecté, mais n'entraine pas l'arrêt de la climatisation, conduisant à un débordement des condensats hors de la cuve et éventuellement une détérioration du dispositif de relevage et/ou de son environnement.  Improper installation of the alarm system is however detrimental to the proper functioning of the condensate removal device, since there is then a risk that an abnormally high level of condensate in the tank is detected, but does not cause the shutdown air conditioning, leading to an overflow of condensate outside the tank and possibly a deterioration of the lifting device and / or its environment.
La maintenance des dispositifs de relevage de condensats peut également être problématique, du fait de la faible accessibilité des différents composants.  The maintenance of condensate lifting devices can also be problematic, due to the poor accessibility of the various components.
En particulier, l'état de la pompe de relevage des condensats doit être contrôlé régulièrement afin de prévenir les fuites de condensats hors de la cuve, dues à son encrassage ou à une panne, et la cuve de réception des condensats doit être régulièrement vidangée et nettoyée afin de prévenir une stagnation des condensats et la création de biofilms.  In particular, the condition of the condensate lift pump must be checked regularly to prevent condensate from leaking out of the tank, due to fouling or failure, and the condensate receiving tank must be regularly drained and cleaned to prevent stagnation of condensate and the creation of biofilms.
Toutefois, la pompe de relevage des condensats et la cuve de réception des condensats ne peuvent généralement être atteintes par le technicien de maintenance qu'en démontant préalablement une ou plusieurs pièces du climatiseur ou de son environnement, ce qui implique une perte conséquente de temps et d'efficacité.  However, the condensate lifting pump and the condensate receiving tank can generally only be reached by the maintenance technician by dismantling one or more parts of the air conditioner or its environment beforehand, which implies a significant loss of time and efficiency.
Enfin, sur le long terme, la fiabilité des dispositifs de détection des niveaux de condensats actuellement utilisés dans les systèmes de relevage n'est pas toujours garantie, leur positionnement pouvant en effet se dérégler.  Finally, in the long term, the reliability of the devices for detecting condensate levels currently used in lifting systems is not always guaranteed, their positioning being able to change.
Les hauteurs relatives des condensats détectées dans la cuve peuvent ainsi être faussées et par conséquent entraîner un risque de défaillance du dispositif de relevage des condensats, par exemple un déclenchement de la pompe trop tardif causant des fuites de condensats. The relative heights of the condensates detected in the tank can thus be distorted and therefore lead to a risk of failure of the condensate lifting device, for example a too late triggering of the pump causing condensate leaks.
Il existe ainsi un besoin d'un dispositif de relevage de condensats qui soit de construction simple, qui soit rapide à installer, qui nécessite peu de connectique, et/ou dont la fiabilité soit optimisée.  There is thus a need for a condensate removal device which is of simple construction, which is quick to install, which requires little connection, and / or whose reliability is optimized.
Il existe également un besoin d'un dispositif de relevage de condensats dont les composants soient facilement et rapidement accessibles de façon à réaliser leur entretien de façon régulière, de manière préventive et/ou curative.  There is also a need for a condensate lifting device whose components are easily and quickly accessible so as to carry out their maintenance on a regular basis, in a preventive and / or curative manner.

Detailed description
5.0 Principe général  5.0 General principle
L'invention propose une nouvelle approche de l'architecture d'un dispositif de relevage de condensais, permettant de simplifier les opérations de fabrication, d'installation et de maintenance du dispositif.  The invention proposes a new approach to the architecture of a condensate lifting device, making it possible to simplify the manufacturing, installation and maintenance operations of the device.
5.0.1 maintenance préventive : accès à la cuve  5.0.1 preventive maintenance: access to the tank
Le dispositif de relevage de condensats comprend notamment une cuve de réception des condensats qui doit faire l'objet d'un contrôle régulier visant à prévenir toute stagnation des condensats qui pourrait provoquer la formation de biofilm, matrice aqueuse et gélatineuse secrétée par les bactéries dans le liquide, et qui favorise la prolifération bactérienne.  The condensate lifting device notably includes a condensate receiving tank which must be regularly checked to prevent any stagnation of condensate which could cause the formation of biofilm, aqueous and gelatinous matrix secreted by bacteria in the liquid, and which promotes bacterial proliferation.
La cuve de réception des condensats doit donc être facilement accessible de façon à être régulièrement vidangée et nettoyée, afin d'éliminer les condensats qui n'auraient pas été évacués par la pompe de relevage des condensats.  The condensate receiving tank must therefore be easily accessible so that it is regularly drained and cleaned, in order to remove condensate which has not been removed by the condensate lifting pump.
Pour ce faire, la cuve de réception des condensats est mobile en translation et/ou en rotation par rapport à un support de pompe, ou premier support, portant une pompe destinée au relevage des condensats récupérés dans la cuve.  To do this, the condensate receiving tank is movable in translation and / or in rotation relative to a pump support, or first support, carrying a pump intended for lifting the condensates recovered in the tank.
Alternativement, la cuve de réception des condensats peut être portée par un support de cuve, ou deuxième support, mobile en translation et/ou en rotation par rapport au support de pompe. En d'autres termes, la cuve peut être un élément monobloc moulé, par exemple en matière plastique, ou un élément solidarisé à un support.  Alternatively, the condensate receiving tank can be carried by a tank support, or second support, movable in translation and / or in rotation relative to the pump support. In other words, the tank can be a one-piece molded element, for example made of plastic, or an element secured to a support.
La cuve de réception des condensats, ou le support de cuve sur lequel elle est montée, peut ainsi prendre deux positions distinctes :  The condensate receiving tank, or the tank support on which it is mounted, can thus take two distinct positions:
une première position dite « position de travail » dans laquelle la cuve est connectée à la pompe, de façon à ce que la pompe puisse extraire les condensats de la cuve ;  a first position called "working position" in which the tank is connected to the pump, so that the pump can extract the condensate from the tank;
une seconde position dite « position de vidange » dans laquelle la cuve est déconnectée de la pompe et extraite du support de pompe, ou à tout le moins déplacée par rapport à celui-ci, de façon à permettre une opération de nettoyage et/ou de vidange des condensats. a second position called "emptying position" in which the tank is disconnected from the pump and extracted from the pump support, or at any the least displaced relative to it, so as to allow a condensate cleaning and / or emptying operation.
Il est ainsi possible d'effectuer aisément un nettoyage régulier de la cuve de réception des condensats, en déplaçant et/ou extrayant cette dernière ou le premier sous-ensemble sur lequel elle est montée, sans qu'il soit nécessaire de démonter une quelconque pièce du climatiseur.  It is thus possible to easily carry out regular cleaning of the condensate receiving tank, by moving and / or extracting the latter or the first sub-assembly on which it is mounted, without the need to dismantle any part. of the air conditioner.
5.0.2 Maintenance curative : accès à la pompe et au circuit électrique  5.0.2 Curative maintenance: access to the pump and the electrical circuit
Selon un autre aspect de l'invention, qui peut selon les modes de réalisation être mis en œuvre indépendamment ou en combinaison avec ce qui précède, le support portant notamment la pompe et ses moyens de pilotage peut être séparé d'un support de base, pour permettre une intervention sur ses composants. Le support de base porte des éléments de connexion électrique (alimentation et connexion avec le climatiseur) et de connexion hydraulique avec la pompe, débrochables par déplacement du support de pompe.  According to another aspect of the invention, which according to the embodiments can be implemented independently or in combination with the above, the support carrying in particular the pump and its control means can be separated from a basic support, to allow intervention on its components. The base support carries elements for electrical connection (power supply and connection with the air conditioner) and hydraulic connection with the pump, withdrawable by moving the pump support.
Le support de base peut-être adapté pour participer au placement, au montage et/ou au maintien du climatiseur.  The basic support can be adapted to participate in the placement, mounting and / or maintenance of the air conditioner.
5.0.3 Sécurité : arrêt de la climatisation en cas de défaillance  5.0.3 Safety: air conditioning shutdown in the event of a fault
Selon un autre aspect de l'invention, qui peut selon les modes de réalisation être mis en œuvre indépendamment ou en combinaison avec ce qui précède, les moyens électriques du support de pompe contrôle directement l'alimentation du climatiseur. Ainsi, le secteur est reçu dans les moyens électriques, puis redirigé vers le climatiseur. En cas de défaillance identifiée, typiquement lorsque le niveau de sécurité est atteint, les moyens électriques agissent directement sur un relais, coupant l'alimentation du climatiseur, sans qu'il soit nécessaire que celui-ci reçoive un signal d'alarme ni ne le traite de façon particulière.  According to another aspect of the invention, which according to the embodiments can be implemented independently or in combination with the above, the electrical means of the pump support directly controls the supply of the air conditioner. Thus, the sector is received in electrical means, then redirected to the air conditioner. In the event of an identified failure, typically when the security level is reached, the electrical means act directly on a relay, cutting the power to the air conditioner, without it being necessary for the latter to receive an alarm signal or to deals with in a particular way.
5.1 exemple de mise en oeuvre  5.1 example of implementation
5.1.1 montage par rapport à un climatiseur  5.1.1 mounting in relation to an air conditioner
La figure 1 représente schématiquement un dispositif de relevage de condensats 1 selon un mode de réalisation de l'invention.  Figure 1 schematically shows a condensate lifting device 1 according to an embodiment of the invention.
Comme visible sur la figure 2, le dispositif de relevage de condensats 1 peut être intégré au boîtier d'un climatiseur mural 100. Dans ce cas, il peut correspondre à un angle du climatiseur, et participer au montage et/ou au maintien de celui-ci. Des moyens particuliers, guides, détrompeurs et/ou moyens de fixation peuvent ainsi être prévus, pour coopérer avec le climatiseur (et plus généralement le système coopérant avec le dispositif de relevage de condensats). As can be seen in FIG. 2, the condensate lifting device 1 can be integrated into the housing of a wall-mounted air conditioner 100. In this case, it can correspond to an angle of the air conditioner, and participate in the mounting and / or maintenance of the latter. Special means, guides, polarizing and / or fixing means can thus be provided, for cooperating with the air conditioner (and more generally the system cooperating with the condensate lifting device).
5.1.2 principe du fonctionnement  5.1.2 operating principle
Toutefois, le dispositif de relevage de condensats 1 pourrait également être placé dans une goulotte ou dans un élément d'architecture intérieure, décoratif ou non, placé à l'extérieur du climatiseur 100 et raccordé à celui-ci par des moyens connus.  However, the condensate lifting device 1 could also be placed in a chute or in an interior architectural element, decorative or otherwise, placed outside the air conditioner 100 and connected to the latter by known means.
Le dispositif de relevage de condensats 1 est destiné à récupérer des gouttelettes de liquide - appelées condensats - issues de la condensation de l'air chaud entrant dans le climatiseur, puis les évacuer.  The condensate lifting device 1 is intended to recover droplets of liquid - called condensates - from the condensation of hot air entering the air conditioner, then evacuate them.
Pour cela, le dispositif de relevage de condensats 1 comprend un certain nombre de composants essentiels, dont le fonctionnement est présenté à suivre.  For this, the condensate lifting device 1 comprises a certain number of essential components, the operation of which is presented to follow.
Un tuyau 2 guide les gouttelettes de condensation vers une cuve 12 de réception des condensats. Il est ici raccordé à un couvercle 121 s'étendant au-dessus de la cuve 12.  A pipe 2 guides the condensation droplets to a tank 12 for receiving the condensates. It is here connected to a cover 121 extending above the tank 12.
Le tuyau 2 est de préférence monté à la verticale, de façon à limiter la stagnation des condensats au sein du tuyau, et ainsi limiter la formation de biofilm.  The pipe 2 is preferably mounted vertically, so as to limit the stagnation of the condensates within the pipe, and thus limit the formation of biofilm.

Pour la même raison, il est aussi prévu que la surface interne de la cuve 12 de récupération des condensats comporte un fond incliné d'un angle a, visible à la figure 5, permettant de diriger les condensats vers une zone de récupération 122 de la cuve 12, plus basse que la zone de chute des gouttelettes.  For the same reason, provision is also made for the internal surface of the condensate recovery tank 12 to have a bottom inclined at an angle a, visible in FIG. 5, making it possible to direct the condensates towards a recovery zone 122 of the tank 12, lower than the droplet drop zone.
Cet angle a peut par exemple être compris entre 2 et 15.  This angle a can for example be between 2 and 15.
5.1.4 pompe  5.1.4 pump
Les condensats récupérés au niveau de la zone de récupération 122 de la cuve 12 sont aspirés sous l'action d'une pompe 13 hydraulique (par exemple de type pompe à piston, centrifuge, péristaltique, à membrane, etc.), puis évacués vers un circuit dédié (non représenté). Un élément d'anti-siphonage et/ou d'anti-retour 14 est prévu à la sortie de la pompe 13 et permet d'éviter tout reflux des condensats par effet de siphon vers la cuve 12 de réception des condensats. The condensates recovered from the recovery zone 122 of the tank 12 are sucked under the action of a hydraulic pump 13 (for example of the piston pump, centrifugal, peristaltic, membrane type, etc.), then evacuated to a dedicated circuit (not shown). An anti-siphoning and / or non-return element 14 is provided at the outlet of the pump 13 and makes it possible to avoid any reflux of the condensates by siphon effect towards the tank 12 for receiving the condensates.
5.1.5 pilotage de la pompe  5.1.5 pump control
La mise en route et l'arrêt de la pompe 13 sont contrôlés par un système de détection du niveau des condensats à l'intérieur de la cuve 12, comprenant un capteur capacitif comportant trois électrodes El, E2, E3, illustrées à la figure 4.  The starting and stopping of the pump 13 is controlled by a system for detecting the level of condensate inside the tank 12, comprising a capacitive sensor comprising three electrodes El, E2, E3, illustrated in FIG. 4 .
D'autres types de capteurs peuvent bien sûr être mis en œuvre, à l'intérieur de la cuve ou à l'extérieur de celle-ci. C'est un avantage du capteur capacitif que de pouvoir placer les électrodes à l'extérieur de la cuve, le long d'une de ses parois. Un autre avantage est que ces électrodes peuvent être formés directement sur le circuit imprimé portant notamment les éléments de pilotage de la pompe, sous la forme d'un dépôt de piste de cuivre ou d'un matériau conducteur similaire, prenant la forme et la dimension souhaitée pour chaque électrode.  Other types of sensors can of course be implemented, inside the tank or outside of it. It is an advantage of the capacitive sensor to be able to place the electrodes outside the tank, along one of its walls. Another advantage is that these electrodes can be formed directly on the printed circuit carrying in particular the control elements of the pump, in the form of a deposit of copper or a similar conductive material, taking the shape and the size. desired for each electrode.
Les électrodes El, E2 et E3 permettent de mesurer une capacité, par rapport à une électrode de référence ER. La capacité Ci mesurée varie selon le niveau de liquide à l'intérieur de la cuve 12 de réception des condensats.  The electrodes El, E2 and E3 make it possible to measure a capacitance, with respect to a reference electrode ER. The capacity Ci measured varies according to the level of liquid inside the tank 12 for receiving the condensates.
La première électrode El est dite « de premier niveau » et permet de créer une capacité Cl ; la deuxième électrode E2 est dite « de second niveau » et permet de créer une capacité C2 ; et la troisième électrode E3 est dite « de niveau d'alarme » et permet de créer une capacité C3.  The first electrode El is said to be “first level” and makes it possible to create a capacitor Cl; the second electrode E2 is said to be “second level” and makes it possible to create a capacitor C2; and the third electrode E3 is called “alarm level” and makes it possible to create a capacitor C3.
Les électrodes El, E2, E3 présentent chacune une longueur, ou hauteur, différente qui correspond sensiblement à un niveau spécifique de condensats à l'intérieur de la cuve 12.  The electrodes E1, E2, E3 each have a different length, or height, which corresponds substantially to a specific level of condensate inside the tank 12.
Ainsi, l'électrode « de premier niveau » El est la plus longue des électrodes, de telle manière que son extrémité inférieure correspond à un niveau minimal de condensats, c'est-à-dire le niveau auquel la pompe 13 doit être arrêtée.  Thus, the “first level” electrode E1 is the longest of the electrodes, so that its lower end corresponds to a minimum level of condensate, that is to say the level at which the pump 13 must be stopped.
L'électrode « de second niveau » E2 a une longueur telle que son extrémité inférieure correspond à un niveau maximal autorisé de condensais, c'est-à-dire le niveau auquel il convient de mettre en route la pompe 13. Ainsi, la pompe 13 est en marche lorsque le niveau des condensats est situé entre les électrodes El et E2. The “second level” electrode E2 has a length such that its lower end corresponds to a maximum authorized level of condensate, that is to say the level at which the pump 13 should be started. Thus, the pump 13 is on when the level of the condensate is located between the electrodes E1 and E2.
Enfin, l'électrode « de niveau d'alarme » E3 est la plus courte des électrodes, de telle manière que son extrémité inférieure correspond à un niveau critique de condensats dans la cuve 12 de réception, auquel il convient de générer une alarme afin d'informer l'utilisateur d'une situation anormale et/ou d'arrêter le fonctionnement du climatiseur. L'alarme, correspondant à un niveau de liquide critique, est générée par un système d'alarme 16.  Finally, the “alarm level” electrode E3 is the shortest of the electrodes, so that its lower end corresponds to a critical level of condensate in the receiving tank 12, at which an alarm must be generated in order to '' inform the user of an abnormal situation and / or stop the operation of the air conditioner. The alarm, corresponding to a critical liquid level, is generated by an alarm system 16.
Le nombre d'électrodes peut être plus ou moins élevé, de façon à doubler les mesures et/ou détecter des niveaux de liquide intermédiaires.  The number of electrodes can be higher or lower, so as to double the measurements and / or detect intermediate liquid levels.
Les électrodes El, E2, E3 et ER sont destinées à être placées de préférence à l'extérieur de la cuve 12 de réception des condensats, à proximité d'une de ses parois latérales, mais pourraient également être positionnées à l'intérieur de la cuve selon certains modes de réalisation de l'invention.  The electrodes E1, E2, E3 and ER are intended to be preferably placed outside the tank 12 for receiving the condensates, near one of its side walls, but could also be positioned inside the tank according to certain embodiments of the invention.
5.2 structure en supports « emboîtés »  5.2 structure in “nested” supports
Les composants du dispositif de relevage de condensats 1 sont regroupés sur trois supports SI, S2, S3, ou sous-ensembles, du dispositif, décrits en relation avec la figure 3.  The components of the condensate lifting device 1 are grouped on three supports SI, S2, S3, or sub-assemblies, of the device, described in relation to FIG. 3.
5.2.1 SI : support de pompe  5.2.1 IF: pump support
Le premier support SI, ou support de pompe, porte la pompe 13 de relevage de condensats. Plus précisément, le premier support SI porte un circuit imprimé 15 qui regroupe l'essentiel des composants, dont la pompe 13. Le premier support SI peut aussi être formé par le circuit imprimé 15 lui-même.  The first support SI, or pump support, carries the condensate lift pump 13. More specifically, the first support SI carries a printed circuit 15 which groups together most of the components, including the pump 13. The first support SI can also be formed by the printed circuit 15 itself.
Le circuit imprimé 15, illustré sur la figure 4, regroupe au moins :  The printed circuit 15, illustrated in FIG. 4, groups together at least:
les électrodes El, E2, E3, formées directement sur le circuit imprimé 15 par découpe de celui-ci et par dépose des pistes de cuivre à la surface des découpes,  the electrodes E1, E2, E3, formed directly on the printed circuit 15 by cutting it and by depositing copper tracks on the surface of the cuts,
le système de pilotage et d'alarme 16,  the control and alarm system 16,
la pompe 13 de relevage de condensats,  the condensate pump 13,
Additionnellement, il peut aussi porter un panneau de contrôle 17 comportant par exemple des diodes électroluminescentes (LEDS) permettant d'indiquer l'état du dispositif de relevage de condensats 1 (en fonctionnement, défectueux, nécessitant une vidange, etc.), une prise USB ou similaire, pour accéder à une mémoire du système 16, pouvant stocker un programme de pilotage que l'on peut mettre à jour et/ou des données de suivi destinées à la maintenance (nombre d'activations de la pompe, quantité de condensats traités, temps de fonctionnement, délai depuis la dernière vidange et/ou maintenance, situations d'alarme,...) et/ou des moyens de commande 18 (mise en marche du dispositif, passage dans un mode particulier, par exemple de maintenance, test,...). Additionally, it can also carry a control panel 17 comprising for example light-emitting diodes (LEDS) making it possible to indicate the state of the condensate removal device 1 (in operation, defective, requiring emptying, etc.), a USB socket or the like, for accessing a memory of the system 16, which can store a control program which can be updated and / or monitoring data intended for maintenance (number of pump activations, quantity of condensate treated, operating time, delay since the last drain and / or maintenance, alarm situations, etc.) and / or control means 18 (switching on the device, switching to a particular mode, for example of maintenance, test, etc.).
Le fait de regrouper tous ces composants sur le circuit imprimé 15 permet d'obtenir un ensemble compact, simple à fabriquer, et évitant au technicien le recours à une pluralité de connectiques entre ces composants.  The fact of grouping all these components on the printed circuit 15 makes it possible to obtain a compact assembly, simple to manufacture, and avoiding the technician having to resort to a plurality of connectors between these components.
5.2.2 52 : support de cuve  5.2.2 52: tank support
Le second support S2, ou support de cuve, porte la cuve 12 de réception des condensats. Dans le mode de réalisation illustré sur la figure 3, le second support S2 est formé par la cuve 12 de réception des condensats elle-même, décrite plus en détail par la suite.  The second support S2, or tank support, carries the tank 12 for receiving the condensates. In the embodiment illustrated in FIG. 3, the second support S2 is formed by the tank 12 for receiving the condensates itself, described in more detail below.
5.2.3 S3 : support de base  5.2.3 S3: basic support
Le troisième support S3, ou support de base, est fixe par rapport au climatiseur, une de ses faces pouvant être solidarisée à une surface de réception (par exemple un mur d'habitation).  The third support S3, or base support, is fixed relative to the air conditioner, one of its faces being able to be secured to a receiving surface (for example a residential wall).
Dans un mode de réalisation particulier, il peut être configuré pour permettre un montage aussi bien à gauche (figure 2) qu'à droite du climatiseur, pour s'adapter plus aisément à différentes conditions de montages. Dans d'autres modes de réalisation, on peut prévoir deux versions du dispositif de relevage, adaptées respectivement à un montage à gauche et à un montage à droite.  In a particular embodiment, it can be configured to allow mounting both on the left (Figure 2) and on the right of the air conditioner, to adapt more easily to different mounting conditions. In other embodiments, two versions of the lifting device can be provided, suitable respectively for mounting on the left and mounting on the right.
L'autre face porte un élément d'anti-siphonage et/ou d'anti-retour 14, prévu pour coopérer avec la sortie 131 de la pompe 13, et le câble électrique 3 destiné à être raccordé au circuit imprimé 15.  The other face carries an anti-siphoning and / or non-return element 14, designed to cooperate with the outlet 131 of the pump 13, and the electric cable 3 intended to be connected to the printed circuit 15.
Le troisième support S3 forme un élément de structure apte à maintenir ou participer au maintien du climatiseur 100 mural, comme illustré sur la figure 2. 5.2.4 mobilité The third support S3 forms a structural element capable of maintaining or participating in the maintenance of the wall-mounted air conditioner 100, as illustrated in FIG. 2. 5.2.4 mobility
Le support de pompe SI, et le support de cuve S2, sont configurés pour être mobiles par rapport au troisième support S3 de façon à pouvoir être extraits du climatiseur par un technicien, pour à réaliser en toute simplicité à la fois les opérations de maintenance préventive et les opérations de maintenance curative.  The pump support SI, and the tank support S2, are configured to be movable relative to the third support S3 so that they can be removed from the air conditioner by a technician, so as to easily carry out both preventive maintenance operations and curative maintenance operations.
Plus précisément, selon un premier aspect de l'invention, le support de cuve S2 portant la cuve 12 de réception des condensats (ou formé de la cuve 12 de réception des condensats), est amovible en translation et/ou en rotation par rapport au support de pompe SI (flèche A).  More specifically, according to a first aspect of the invention, the tank support S2 carrying the tank 12 for receiving the condensates (or formed from the tank 12 for receiving the condensates), is removable in translation and / or in rotation relative to the pump support SI (arrow A).
Cet aspect fait l'objet du paragraphe 5.3 et fait référence en particulier aux figures 5A à 5C.  This aspect is the subject of paragraph 5.3 and refers in particular to FIGS. 5A to 5C.
Selon un deuxième aspect aspect de l'invention, le support de pompe SI, portant le circuit imprimé 15 muni de la pompe 13 (ou formé du circuit imprimé 15 muni de la pompe 13), est amovible en translation et/ou en rotation par rapport au support de base S3 (flèche B).  According to a second aspect aspect of the invention, the pump support SI, carrying the printed circuit 15 provided with the pump 13 (or formed from the printed circuit 15 provided with the pump 13), is removable in translation and / or in rotation by compared to the basic support S3 (arrow B).
Cet aspect fait l'objet du paragraphe 5.4 et fait référence en particulier à la figure This aspect is the subject of paragraph 5.4 and refers in particular to the figure
6. 6.
Ainsi, selon le mode de réalisation illustré figure 3, le dispositif de relevage de condensats 1 met en œuvre un système de « double tiroir » : le premier « tiroir » correspond au support de cuve S2, amovible par rapport au support de pompe SI et le second « tiroir » correspond au support de pompe SI amovible par rapport au support de base S3.  Thus, according to the embodiment illustrated in FIG. 3, the condensate lifting device 1 implements a “double drawer” system: the first “drawer” corresponds to the tank support S2, removable relative to the pump support SI and the second “drawer” corresponds to the removable pump support SI with respect to the base support S3.
Un mécanisme peut être prévu pour déclencher l'extraction du support de cuve S2 (ou la cuve 12) et/ou du support de pompe SI par rapport au climatiseur 100, et/ou leur réinsertion dans le climatiseur 100, au moins partielle.  A mechanism may be provided to trigger the extraction of the tank support S2 (or the tank 12) and / or of the pump support SI relative to the air conditioner 100, and / or their reinsertion into the air conditioner 100, at least partially.
Par exemple, un tel mécanisme peut mettre en œuvre un ressort qui permet, en réponse à un appui sur un actuateur ou la plaque, ou cache, 19, d'entraîner un déverrouillage et un déplacement du support de cuve S2 par rapport au climatiseur, grâce à la réalisation d'une pression sur la surface externe du support. Une approche similaire peut être appliqué pour le support de pompe SI. Dans le mode de réalisation illustré, le cache 19 est prévu notamment pour occulter une ouverture du climatiseur 100 au travers de laquelle les supports SI et S2 se déplacent. Il peut également porter les éléments d'interface. For example, such a mechanism can implement a spring which makes it possible, in response to a press on an actuator or the plate, or cover, 19, to cause an unlocking and a displacement of the tank support S2 relative to the air conditioner, by applying pressure on the external surface of the support. A similar approach can be applied for the SI pump support. In the illustrated embodiment, the cover 19 is provided in particular to conceal an opening of the air conditioner 100 through which the supports SI and S2 move. It can also carry the interface elements.
Cet aspect fait l'objet du paragraphe 5.4 et fait référence en particulier à la figure 7.  This aspect is the subject of paragraph 5.4 and refers in particular to Figure 7.
Les caractéristiques qui font l'objet de chacun des paragraphes 5.3, à 5.6 ci-après peuvent être mises en œuvre conjointement ou séparément, selon les modes de réalisation.  The characteristics which are the subject of each of paragraphs 5.3, to 5.6 below can be implemented jointly or separately, depending on the embodiments.
5. 3 Amovibilité du support de cuve portant ou formant la cuve de réception des condensais 5.3 Removability of the tank support carrying or forming the condensate receiving tank
Selon un premier aspect de l'invention, illustré sur la figure 5A, la cuve 12 de réception des condensats est amovible par rapport au premier support SI, ou support de pompe.  According to a first aspect of the invention, illustrated in FIG. 5A, the tank 12 for receiving the condensates is removable relative to the first support SI, or pump support.
La cuve 12 de réception des condensats peut ainsi être déplacée par rapport au support de pompe SI et prendre deux positions distinctes :  The condensate receiving tank 12 can thus be moved relative to the pump support SI and take two distinct positions:
une position dite « position de travail », ou fonctionnelle, dans laquelle la cuve 12 est logée dans le support SI (logé lui-même dans le climatiseur 100) et connectée à la pompe 13 du support SI et de façon à permettre l'évacuation des condensats, et  a position called "working position", or functional, in which the tank 12 is housed in the support SI (itself housed in the air conditioner 100) and connected to the pump 13 of the support SI and so as to allow evacuation condensates, and
une position dite « position de vidange », ou de nettoyage, dans laquelle la cuve 12 est extraite du support SI (et donc du climatiseur 100) et déconnectée de la pompe, de façon à permettre une opération de nettoyage et/ou de vidange de condensats.  a position called “emptying position”, or cleaning, in which the tank 12 is extracted from the support SI (and therefore from the air conditioner 100) and disconnected from the pump, so as to allow a cleaning and / or emptying operation of condensates.
Dans le cadre d'une opération de nettoyage ou vidange des condensats, le support de pompe SI et le support de base S3 forment un unique ensemble, immobile par rapport au climatiseur 100, par rapport auquel la cuve 12 de réception des condensats peut être déplacée. En d'autres termes, la cuve 12 de réception des condensats est amovible par rapport au sous-ensemble formé par le support de pompe SI et le support de base S3.  As part of a condensate cleaning or draining operation, the pump support SI and the base support S3 form a single assembly, stationary relative to the air conditioner 100, relative to which the tank 12 for receiving the condensates can be moved . In other words, the tank 12 for receiving the condensates is removable relative to the sub-assembly formed by the pump support SI and the base support S3.
Selon une variante non illustrée, la cuve 12 de réception des condensais pourrait également être montée sur un support de cuve S2 (non illustré), par exemple un châssis de tiroir, lui-même amovible par rapport au support de pompe SI, de façon à ce que la cuve 12 puisse prendre les positions de travail et de vidange précitées. According to a variant not illustrated, the tank 12 for receiving the condensates could also be mounted on a tank support S2 (not shown), for example a drawer frame, itself removable with respect to the pump support SI, so that the tank 12 can take the working and emptying positions above.
La figure 5A représente, selon un mode de réalisation particulier, la cuve 12 de réception des condensats extraite du climatiseur. La cuve 12 de réception des condensats est extraite par le côté du climatiseur (flèche A) selon un mouvement de translation horizontale, à la manière d'un tiroir.  FIG. 5A represents, according to a particular embodiment, the tank 12 for receiving the condensates extracted from the air conditioner. The condensate receiving tank 12 is extracted from the side of the air conditioner (arrow A) in a horizontal translational movement, in the manner of a drawer.
Dans d'autres mises en œuvre, la cuve ou son support peut effectuer d'autres mouvements par rapport au support SI, et être extraite par exemple selon un mouvement de basculement (rotation angulaire de la cuve), comme illustré sur la figure 5B, ou extraite par le dessous du climatiseur, comme illustré sur la figure 5C (approche permettant la mise en œuvre d'électrodes sont situées à l'intérieur de la cuve 12 par exemple). D'autres déplacements, combinant rotation et translation, ou encore un vissage (quart de tour par exemple).  In other implementations, the tank or its support can make other movements relative to the support SI, and be extracted for example according to a tilting movement (angular rotation of the tank), as illustrated in FIG. 5B, or extracted from below the air conditioner, as illustrated in FIG. 5C (approach allowing the implementation of electrodes are located inside the tank 12 for example). Other movements, combining rotation and translation, or even a screwing (quarter turn for example).
Le couvercle 121 de la cuve comprend sur au moins un de ses côtés longitudinaux un rail de guidage 122 d'au moins une bordure supérieure de la cuve 12 de réception des condensats. Dans des variantes, les moyens de guidage et de maintien de la cuve ou de son support peuvent être indépendants de ce couvercle.  The cover 121 of the tank comprises on at least one of its longitudinal sides a guide rail 122 of at least one upper edge of the tank 12 for receiving the condensates. In variants, the means for guiding and holding the tank or its support can be independent of this cover.
La cuve 12 peut ainsi facilement être déplacée au moins partiellement par rapport au couvercle 121, et hors du climatiseur. Il peut être prévu que le déplacement de la cuve en dehors de la position de travail interrompt automatiquement le climatiseur, pour limiter la production de condensats, et/ou déplace un clapet d'obturation de l'arrivée des condensats.  The tank 12 can thus easily be moved at least partially relative to the cover 121, and out of the air conditioner. It can be provided that the movement of the tank outside the working position automatically interrupts the air conditioner, to limit the production of condensate, and / or moves a shutter valve for the arrival of condensate.
Selon l'invention, un utilisateur ou un technicien de maintenance peut ainsi facilement et rapidement vidanger la cuve 12 de réception des condensats ou effectuer un contrôle de son état, notamment pour s'assurer de l'absence de biofilm, en faisant simplement coulisser la cuve 12 de réception des condensats, par rapport au support de pompe SI, hors du dispositif de relevage des condensats 1.  According to the invention, a user or a maintenance technician can thus easily and quickly drain the tank 12 for receiving the condensates or carry out a check of its state, in particular to ensure the absence of biofilm, by simply sliding the tank 12 for receiving the condensates, with respect to the pump support SI, outside the condensate lifting device 1.
Lorsque la cuve 12 est en position de travail, c'est-à-dire totalement insérée dans le dispositif, la sortie 124 de la cuve 12 s'emboîte avec l'entrée 131 de la pompe 13 de relevage des condensats, de façon que la cuve 12 et la pompe 13 soient en connexion directe l'une avec l'autre et que la pompe 13 puisse évacuer les condensats. When the tank 12 is in the working position, that is to say fully inserted into the device, the outlet 124 of the tank 12 is fitted with the inlet 131 of the pump 13 of condensate removal, so that the tank 12 and the pump 13 are in direct connection with each other and that the pump 13 can remove the condensate.
Aucune action manuelle sur la connectique n'est donc nécessaire.  No manual action on the connectors is therefore necessary.
Par ailleurs, lorsque la cuve 12 est dans la position de travail, une des ses parois latérales s'étend à proximité des électrodes El, E2, E3 et ER, de préférence à moins de 5 mm de façon à garantir le bon fonctionnement du système de détection du niveau de condensats.  Furthermore, when the tank 12 is in the working position, one of its side walls extends near the electrodes El, E2, E3 and ER, preferably within 5 mm so as to guarantee the proper functioning of the system. condensate level detection.
Dans l'exemple illustré, les électrodes El, E2, E3 et ER s'étendent à l'extérieur de la cuve 12 de réception des condensats, au voisinage d'une paroi de la cuve, lorsque celle- ci est en position de travail.  In the example illustrated, the electrodes E1, E2, E3 and ER extend outside the tank 12 for receiving the condensates, in the vicinity of a wall of the tank, when the latter is in the working position. .
Toutefois, les électrodes pourraient s'étendre à l'intérieur de la cuve, et par exemple être en contact avec les condensats, la cuve étant alors amovible dans le sens de la longueur des électrodes de façon à ne pas rentrer en contact avec ces dernières au cours de son déplacement. D'autres types de capteurs, connus en eux-mêmes, pourraient également être utilisés.  However, the electrodes could extend inside the tank, and for example be in contact with the condensates, the tank then being removable in the lengthwise direction of the electrodes so as not to come into contact with the latter. during its movement. Other types of sensors, known in themselves, could also be used.
5.4 Amovibilité du support de pompe portant ou formé par la pompe de relevage des condensats 5.4 Removability of the pump support carrying or formed by the condensate lifting pump
Selon un autre aspect de l'invention, illustré sur la figure 6, le support de pompe SI est monté amovible, ou à tout le moins mobile, par rapport au troisième support S3, ou support de base.  According to another aspect of the invention, illustrated in FIG. 6, the pump support SI is removably mounted, or at the very least movable, relative to the third support S3, or base support.
Le support de pompe SI peut ainsi être déplacé par rapport au support de base S3 et prendre deux positions distinctes :  The pump support SI can thus be moved relative to the base support S3 and take two distinct positions:
une position dite « position de fonctionnement », ou fonctionnelle, dans laquelle le support de pompe SI est logé dans le support de base S3 (et donc dans le climatiseur 100) et des connexions électrique et hydraulique sont établies entre le support de pompe SI et le support de base S3, de façon à permettre l'évacuation des condensats, et  a position called “operating position”, or functional, in which the pump support SI is housed in the base support S3 (and therefore in the air conditioner 100) and electrical and hydraulic connections are established between the pump support SI and the basic support S3, so as to allow the evacuation of the condensates, and
une position dite « position de maintenance », dans laquelle le support SI est extrait du support S3 (et donc du climatiseur 100) et les connexions électrique et hydraulique sont interrompues, de façon à permettre une opération de maintenance de la pompe ou plus généralement des composants portés par le circuit imprimé 15. a position called "maintenance position", in which the support SI is extracted from the support S3 (and therefore from the air conditioner 100) and the connections electric and hydraulic are interrupted, so as to allow a maintenance operation of the pump or more generally of the components carried by the printed circuit 15.
Le support de pompe SI prend la forme d'une plaque sensiblement rectangulaire tandis que le support de base S3, solidaire du climatiseur 100, comprend une découpe de réception 11 de forme complémentaire au support de pompe SI.  The pump support SI takes the form of a substantially rectangular plate while the base support S3, integral with the air conditioner 100, comprises a receiving cutout 11 of shape complementary to the pump support SI.
Le support de pompe SI peut coulisser (flèche B) à l'intérieur du support de base S3 par l'intermédiaire d'au moins un rail de guidage (non représenté), de préférence deux rails de guidage.  The pump support SI can slide (arrow B) inside the base support S3 by means of at least one guide rail (not shown), preferably two guide rails.
L'extraction du support de pompe SI hors du climatiseur 100, peut également être réalisée au moyen d'autres mouvements de coulissement, basculement ou rotation.  The extraction of the pump support SI from the air conditioner 100 can also be carried out by means of other sliding, tilting or rotating movements.
Dans le cadre d'une opération de maintenance, le support de pompe SI et le support de cuve S2 (ou la cuve 12 seule) peuvent former un unique ensemble amovible par rapport au climatiseur 100 ou être séparés l'un de l'autre.  As part of a maintenance operation, the pump support SI and the tank support S2 (or the tank 12 alone) can form a single removable assembly with respect to the air conditioner 100 or be separated from each other.
En d'autres termes, le sous-ensemble formé par le support de pompe SI et le support de cuve S2 est amovible par rapport au support de base S3.  In other words, the sub-assembly formed by the pump support SI and the tank support S2 is removable with respect to the base support S3.
Le support de pompe SI porte le circuit imprimé 15 (dans un mode de réalisation, le support peut être formé par le circuit imprimé lui-même) qui porte lui-même les composants du dispositif de relevage de condensats 1 qui sont les plus susceptibles de devoir être réparés et/ou échangés par un technicien dans le cadre d'une maintenance.  The pump support SI carries the printed circuit 15 (in one embodiment, the support can be formed by the printed circuit itself) which itself carries the components of the condensate removal device 1 which are most likely to have to be repaired and / or replaced by a technician as part of maintenance.
Un avantage d'une telle structure est qu'il est facile et rapide pour le technicien d'extraire le support de pompe SI du climatiseur 100, sans outillage particulier, en le faisant coulisser à la manière d'un tiroir, et d'avoir accès aux composants en question. Aucune intervention préalable de déconnexion électrique ou hydraulique n'est nécessaire.  An advantage of such a structure is that it is quick and easy for the technician to extract the pump support SI from the air conditioner 100, without special tools, by sliding it in the manner of a drawer, and having access to the components in question. No prior electrical or hydraulic disconnection is necessary.
Par exemple, le technicien peut réparer ou remplacer la pompe 13 qui est susceptible de s'encrasser ou de tomber en panne, sans qu'il soit nécessaire de démonter le climatiseur.  For example, the technician can repair or replace the pump 13 which is likely to become dirty or break down, without the need to dismantle the air conditioner.
Lorsque le support SI est en position de fonctionnement, c'est-à-dire totalement inséré dans le climatiseur 100, la sortie 131 de la pompe 13 est connectée à un élément d'anti-siphonage ou d'anti-retour 14, établissant une connexion hydraulique entre les supports SI et S3, et un connecteur électrique 151 du circuit imprimé 15 est emboîté avec un connecteur complémentaire 32 recevant l'extrémité du câble électrique 3, établissant une connexion électrique entre les supports SI et S3. When the support SI is in the operating position, that is to say fully inserted in the air conditioner 100, the output 131 of the pump 13 is connected to an element anti-siphoning or non-return 14, establishing a hydraulic connection between the supports SI and S3, and an electrical connector 151 of the printed circuit 15 is fitted with a complementary connector 32 receiving the end of the electrical cable 3, establishing an electrical connection between the supports SI and S3.
Les connexions hydraulique et électrique sont conçues de façon que les différents éléments s'emboîtent sans que le technicien ne doive agir sur la connectique. Le déplacement de connexion ou de déconnexion se fait ainsi parallèlement à l'axe de déplacement du support SI.  The hydraulic and electrical connections are designed so that the various elements fit together without the technician having to act on the connections. The movement of connection or disconnection is thus made parallel to the axis of movement of the support SI.
5.5 Système d'alarme 5.5 Alarm system
Comme précisé dans les paragraphes précédents, la pompe 13 de relevage des condensats, le capteur et les moyens de pilotage sont portés par le circuit imprimé 15, lui- même monté sur, ou formant, le support de pompe SI.  As specified in the preceding paragraphs, the condensate pump 13, the sensor and the control means are carried by the printed circuit 15, itself mounted on, or forming, the pump support SI.
Cette configuration procure un avantage non négligeable par rapport à l'art antérieur et permet notamment de simplifier sensiblement l'installation de la pompe 13.  This configuration provides a significant advantage over the prior art and in particular makes it possible to significantly simplify the installation of the pump 13.
Il n'est donc plus nécessaire de placer la pompe à l'extérieur du climatiseur 100, après l'installation de ce dernier, parfois dans des zones difficiles d'accès (comme un faux plafond ou une goulotte), et d'établir des liaisons hydraulique et électrique avec celle-ci.  It is therefore no longer necessary to place the pump outside of the air conditioner 100, after the installation of the latter, sometimes in areas which are difficult to access (such as a false ceiling or a duct), and to establish hydraulic and electrical connections with it.
Selon un autre aspect particulier de l'invention, Il n'est pas non plus nécessaire d'utiliser un câble d'alarme devant agir sur le climatiseur, pour l'arrêter, en cas de défaillance du dispositif de relevage.  According to another particular aspect of the invention, it is also not necessary to use an alarm cable having to act on the air conditioner, to stop it, in the event of failure of the lifting device.
En effet, comme illustré sur le schéma de la figure 8, l'alimentation électrique du climatiseur se fait par l'intermédiaire du dispositif de relevage, qui peut interrompre directement cette alimentation, sans l'intermédiaire d'un signal d'alarme, en cas de besoin.  In fact, as illustrated in the diagram in FIG. 8, the power supply to the air conditioner is done by means of the lifting device, which can directly interrupt this supply, without the intermediary of an alarm signal, in when needed.
Ainsi, les risques de mauvais câblage de l'alarme, et a fortiori de dysfonctionnement ou détérioration du dispositif de relevage de condensats sont sensiblement réduits. Le circuit imprimé 15 et tous les éléments qu'il porte (pompe 13, système d'alarme 16, panneau de contrôle 17, commande 18 etc.) sont alimentés en électricité par un unique câble d'alimentation 3, qui assure également l'alimentation du climatiseur. Thus, the risks of incorrect wiring of the alarm, and a fortiori of malfunction or deterioration of the condensate removal device are significantly reduced. The printed circuit 15 and all the elements it carries (pump 13, alarm system 16, control panel 17, control 18 etc.) are supplied with electricity by a single power cable 3, which also ensures the air conditioner supply.
Il peut notamment s'agir d'un câble standard à quatre brins :  It can in particular be a standard cable with four strands:
deux brins 81, 82 sont reliés au secteur, et alimentent en conséquence le dispositif de relevage, via des moyens 85 de transformation du courant et de la tension nécessaires ;  two strands 81, 82 are connected to the sector, and consequently supply the lifting device, via means 85 for transforming the necessary current and voltage;
deux brins 83, 84 assurent l'alimentation du climatiseur, via un relais 86 prévu à cet effet sur le circuit imprimé.  two strands 83, 84 supply the air conditioner via a relay 86 provided for this purpose on the printed circuit.
L'alimentation du climatiseur est donc reçue par l'intermédiaire du courant reçu du secteur sur les brins 81, 82, lorsque le relais 86 est passant. En cas de problème détecté, l'électronique du dispositif de relevage agit directement sur le relais 86, qui devient non passant. L'alimentation du climatiseur est ainsi immédiatement interrompue.  The power supply of the air conditioner is therefore received via the current received from the sector on the strands 81, 82, when the relay 86 is conducting. In the event of a detected problem, the electronics of the lifting device acts directly on relay 86, which becomes non-conducting. The power to the air conditioner is immediately interrupted.
Ainsi, l'installateur n'a à connecter, sur le climatiseur, que les brins 83, 84, sans se préoccuper d'un quelconque brin portant un signal d'alarme, et à relier au secteur les brins 81, 82.  Thus, the installer only has to connect the strands 83, 84 to the air conditioner, without worrying about any strand carrying an alarm signal, and to connect the strands 81, 82 to the sector.
Les moyens de pilotage 86, qui reçoivent les signaux représentatifs des niveaux de condensats correspondants aux électrodes El, E2 et E3, produisent un signal d'alarme 87 qui coupe le relais 86, lorsque le niveau de sécurité (électrode E3) est atteint. Ils pilotent par ailleurs la pompe, en fonction des niveaux minimal et maximal.  The control means 86, which receive the signals representative of the condensate levels corresponding to the electrodes E1, E2 and E3, produce an alarm signal 87 which cuts off the relay 86, when the safety level (electrode E3) is reached. They also control the pump, according to the minimum and maximum levels.
5.6 Cache d'occultation d'une ouverture du climatiseur 5.6 Shade cover for opening the air conditioner
Selon un autre aspect de l'invention, un cache 19, par exemple en élastomère, est prévu pour occulter l'ouverture d'extraction par laquelle passent le premier support SI et le deuxième support S2 au cours de leur déplacement par rapport au troisième support S3.  According to another aspect of the invention, a cover 19, for example made of elastomer, is provided to obscure the extraction opening through which the first support SI and the second support S2 pass during their movement relative to the third support S3.
Le cache 19 peut par exemple être prévu pour s'étendre sur la surface latérale externe du climatiseur 100. Il peut être amovible, son basculement ou son retrait permettant d'accéder au support de cuve S2 (ou de la cuve 12 seule), de façon à extraire celui-ci du climatiseur 100, directement ou à l'aide d'un outil adapté, et pouvoir effectuer les opérations de vidange ou nettoyage de la cuve. The cover 19 can for example be provided to extend over the external lateral surface of the air conditioner 100. It can be removable, its tilting or removal allowing access to the tank support S2 (or of the tank 12 alone), so as to extract it from the air conditioner 100, directly or using a suitable tool, and be able to perform emptying or cleaning the tank.
Le cache 19 peut également être adapté pour permettre d'accéder, via son basculement, à un élément de préhension (non représenté) du support de pompe SI, de façon à extraire celui-ci du climatiseur 100 et pouvoir accéder à l'ensemble des composants afin d'effectuer les opérations de maintenance.  The cover 19 can also be adapted to allow access, via its tilting, to a gripping element (not shown) of the pump support SI, so as to extract the latter from the air conditioner 100 and be able to access all of the components in order to carry out maintenance operations.
Le cache 19 peut aussi être porté directement par le deuxième support S2 (ou cuve 12), ou le premier support SI, de façon à venir obturer l'ouverture d'extraction lorsque les supports sont logés dans le climatiseur 100.  The cover 19 can also be carried directly by the second support S2 (or tank 12), or the first support SI, so as to close off the extraction opening when the supports are housed in the air conditioner 100.
Ce cache 19 permet d'éviter que des poussières rentrent à l'intérieur du dispositif de relevage 1 et de sceller l'ouverture d'extraction du climatiseur 100 de façon à obtenir une surface externe esthétique. Il peut également porter des éléments d'interface (diodes LED, boutons, connecteurs, ...).  This cover 19 makes it possible to prevent dust from entering the interior of the lifting device 1 and to seal the extraction opening of the air conditioner 100 so as to obtain an external aesthetic surface. It can also carry interface elements (LEDs, buttons, connectors, ...).
