Description

DESCRIPTION DESCRIPTION
TITRE : Tête de nettoyage équipée d’un dispositif de nettoyage humideTITLE: Cleaning head equipped with a wet cleaning device
Domaine technique Technical area
[0001] La présente invention concerne le domaine des appareils de nettoyage domestiques comprenant une tête de nettoyage équipée d’un dispositif de nettoyage humide permettant de réaliser un nettoyage humide d’une surface à nettoyer. The present invention relates to the field of household cleaning appliances comprising a cleaning head equipped with a wet cleaning device for carrying out wet cleaning of a surface to be cleaned.
[0002] La présente invention se rapporte plus particulièrement aux aspirateurs domestiques, par exemple du type balai ou traineau, permettant d’aspirer des poussières et des déchets de faible granulométrie présents sur une surface à nettoyer, qui peut par exemple être du carrelage, du parquet, du stratifié, de la moquette ou un tapis, et de réaliser simultanément un nettoyage humide de la surface à nettoyer lorsque cette dernière est un sol lisse. The present invention relates more particularly to domestic vacuum cleaners, for example of the broom or sled type, making it possible to suck up dust and small-grained waste present on a surface to be cleaned, which can for example be tiles, parquet, laminate, carpet or rug, and simultaneously wet clean the surface to be cleaned when the latter is a smooth floor.
Etat de la technique State of the art
[0003] Le document US7640626 divulgue une tête de nettoyage pour appareil de nettoyage domestique, comprenant : [0003] The document US7640626 discloses a cleaning head for a household cleaning device, comprising:
- un corps principal comportant une semelle munie d’une face inférieure qui est configurée pour être orientée vers une surface à nettoyer, - a main body comprising a sole provided with a lower face which is configured to be oriented towards a surface to be cleaned,
- un dispositif de nettoyage humide comportant un support de serpillère qui est fixé de manière amovible au corps principal et une serpillère qui est configurée pour être en contact avec la surface à nettoyer, la serpillère comportant une partie centrale qui est fixée de manière amovible au support de serpillère et une partie périphérique qui est annulaire et qui dépasse d’un bord périphérique du support de serpillère. - a wet cleaning device comprising a mop holder which is removably attached to the main body and a mop which is configured to contact the surface to be cleaned, the mop comprising a central part which is removably attached to the holder of mop and a peripheral part which is annular and which protrudes from a peripheral edge of the mop holder.
[0004] Le support de serpillère dépasse d’un bord arrière du corps principal de manière à former une zone d’appui configurée pour permettre à un utilisateur d’exercer une force d’appui sur ladite zone d’appui avec son pied de manière à permettre un démontage du support de serpillère lorsque simultanément l’utilisateur exerce une force d’appui sur la zone d’appui et soulève la tête de nettoyage. [0004] The mop support protrudes from a rear edge of the main body so as to form a support zone configured to allow a user to exert a bearing force on said bearing zone with his foot so as to allow disassembly of the mop support when the user simultaneously exerts a bearing force on the bearing zone and raises the cleaning head .
[0005] Un tel démontage du support de serpillère permet de pouvoir ensuite retirer la serpillère du support de serpillère en vue du nettoyage ou du remplacement de la serpillère, et ce sans nécessiter d’une part un retournement de la tête de nettoyage pour avoir accès à la serpillère (qui serait susceptible d’une part d’entraîner une chute ultérieure de la tête de nettoyage et donc une dégradation de cette dernière, et d’autre part d’entraîner une fuite d’eau sale résiduelle contenue dans la tête de nettoyage et ainsi une salissure du sol venant d’être nettoyé) et d’autre part une manipulation difficile de la tête de nettoyage (à savoir une retenue du corps principal avec une main et un retrait de la serpillère avec l’autre main). [0005] Such dismantling of the mop holder makes it possible to then remove the mop from the mop holder for cleaning or replacement of the mop, and this without requiring on the one hand a reversal of the cleaning head to gain access to the mop (which would be likely on the one hand to lead to a subsequent fall of the cleaning head and therefore a deterioration of the latter, and on the other hand to cause a leak of residual dirty water contained in the cleaning head cleaning and thus soiling of the floor that has just been cleaned) and on the other hand difficult handling of the cleaning head (namely holding the main body with one hand and removing the mop with the other hand).
[0006] Cependant, une telle configuration du support de serpillère requiert, lorsque ce dernier est rotatif, d’équiper le support de serpillère de moyens d’accouplement spécifiques afin de permettre un accouplement amovible entre le support de serpillère et le mécanisme d’entraînement en rotation équipant le corps principal, ce qui augmente les coûts de fabrication de la tête de nettoyage. [0006] However, such a configuration of the mop support requires, when the latter is rotatable, to equip the mop support with specific coupling means in order to allow a removable coupling between the mop support and the drive mechanism in rotation equipping the main body, which increases the manufacturing costs of the cleaning head.
[0007] En outre, un démontage répété du support de serpillère est susceptible d’entraîner une usure des moyens d’accouplement précités et/ou une casse du support de serpillère qui sont susceptibles de nuire au fonctionnement de la tête de nettoyage. [0007] In addition, repeated dismantling of the mop holder is liable to cause wear of the aforementioned coupling means and/or breakage of the mop holder which are liable to adversely affect the operation of the cleaning head.
Résumé de l’invention Summary of the Invention
[0008] La présente invention vise à remédier à tout ou partie de ces inconvénients. The present invention aims to remedy all or part of these drawbacks.
[0009] Le problème technique à la base de l’invention consiste notamment à fournir une tête de nettoyage qui permette un retrait aisé, sécurisé et rapide d’une serpillère en vue de son nettoyage ou son remplacement, tout en limitant les coûts de fabrication de la tête de nettoyage. [0009] The technical problem underlying the invention consists in particular in providing a cleaning head which allows easy, secure and rapid removal of a mop for cleaning or replacement, while limiting the manufacturing costs of the cleaning head.
[0010] A cet effet, la présente invention concerne une tête de nettoyage pour appareil de nettoyage domestique, comprenant : To this end, the present invention relates to a cleaning head for a household cleaning device, comprising:
- un corps principal comportant une semelle munie d’une face inférieure qui est configurée pour être orientée vers une surface à nettoyer, - a main body comprising a sole provided with a lower face which is configured to be oriented towards a surface to be cleaned,
- un dispositif de nettoyage humide comportant un support de serpillère qui s’étend au moins en partie sous la semelle et une serpillère qui est configurée pour être en contact avec la surface à nettoyer, la serpillère comportant une partie centrale qui est fixée de manière amovible au support de serpillère et une partie périphérique qui dépasse d’un bord périphérique du support de serpillère et qui s’étend sur au moins une partie du pourtour de la partie centrale. - a wet cleaning device comprising a mop support which extends at least partly under the sole and a mop which is configured to be in contact with the surface to be cleaned, the mop comprising a central part which is removably attached to the mop holder and a peripheral part which protrudes from a peripheral edge of the mop holder and which extends over at least part of the periphery of the central part.
[0011] La serpillère dépasse d’un bord externe du corps principal d’une distance de dépassement supérieure à 10 mm, de préférence comprise entre 10 et 30 mm, et le support de serpillère est situé en retrait dudit bord externe du corps principal ou dépasse dudit bord externe du corps principal d’une distance de saillie inférieure ou égale à 5 mm. En outre, la face inférieure de la semelle comporte une surface d’appui configurée pour exercer une force d’appui sur au moins une portion de la partie périphérique de la serpillère qui est située en regard de la face inférieure de la semelle lorsque la serpillère repose sur une surface à nettoyer. [0011] The mop protrudes from an outer edge of the main body by an overrun distance greater than 10 mm, preferably between 10 and 30 mm, and the mop support is set back from said outer edge of the main body or protrudes from said outer edge of the main body by a protrusion distance less than or equal to 5 mm. In addition, the underside of the sole comprises a bearing surface configured to exert a bearing force on at least a portion of the peripheral part of the mop which is located opposite the underside of the sole when the mop rests on a surface to be cleaned.
[0012] En d’autres termes, la serpillère s’étend au-delà d’un bord externe du corps principal d’une distance de dépassement comprise entre 15 et 30 mm, et le support de serpillère est situé en retrait dudit bord externe du corps principal ou s’étend au-delà dudit bord externe du corps principal d’une distance de saillie inférieure ou égale à 5 mm. [0012] In other words, the mop extends beyond an outer edge of the main body by an overrun distance of between 15 and 30 mm, and the mop support is set back from said outer edge. of the main body or extends beyond said outer edge of the main body by a protrusion distance less than or equal to 5 mm.
[0013] La portion de la serpillère qui dépasse du bord externe du corps principal forme plus particulièrement une zone d’appui configurée pour permettre à un utilisateur d’exercer une force d’appui sur ladite zone d’appui avec son pied. [0013] The portion of the mop which protrudes from the outer edge of the main body more particularly forms a support zone configured to allow a user to exert a bearing force on said bearing zone with his foot.
[0014] Une telle configuration de la tête de nettoyage selon la présente invention permet à un utilisateur de pouvoir exercer aisément une force d’appui sur la portion de la partie périphérique de la serpillère qui s’étend au-delà du bord externe du corps principal, et donc de pouvoir aisément retirer la serpillère du support de serpillère en soulevant la tête de nettoyage tout en maintenant la force d’appui exercée sur la serpillère. En particulier, la distance de dépassement et la disposition du support de serpillère par rapport au corps principal sont définis pour empêcher ou du moins pour réduire sensiblement les risques qu’un utilisateur puisse exercer une force d’appui sur le support de serpillère lors d’une opération de retrait de cette dernière avec l’un de ses pieds. [0014] Such a configuration of the cleaning head according to the present invention allows a user to be able to easily exert a pressing force on the portion of the peripheral part of the mop which extends beyond the outer edge of the body. main, and therefore to be able to easily remove the mop from the mop holder by lifting the cleaning head while maintaining the pressing force exerted on the mop. In particular, the overhang distance and the arrangement of the mop holder relative to the main body are defined to prevent or at least to significantly reduce the risks that a user can exert a pressing force on the mop holder when a removal operation of the latter with one of his feet.
[0015] La portion de la partie périphérique de la serpillère faisant saillie du corps principal n’est pas plaquée contre la surface à nettoyer par le support de serpillère et présente donc des performances de nettoyage limitées. La distance de dépassement est plus particulièrement définie pour assurer un retrait aisé de la serpillère du support de serpillère et pour conférer à la serpillère des performances de nettoyage satisfaisantes. [0015] The portion of the peripheral part of the mop projecting from the main body is not pressed against the surface to be cleaned by the mop support and therefore has limited cleaning performance. The overrun distance is more particularly defined to ensure easy removal of the mop from the mop holder and to give the mop satisfactory cleaning performance.
[0016] Ainsi, la tête de nettoyage selon la présente invention permet un retrait aisé, rapide et sécurisé de la serpillère du support de serpillère sans nécessiter en particulier un retournement de la tête de nettoyage et une manipulation complexe de cette dernière et tout en limitant les coûts de fabrication de la tête de nettoyage. [0016] Thus, the cleaning head according to the present invention allows easy, quick and secure removal of the mop from the mop holder without in particular requiring the cleaning head to be turned over and complex manipulation of the latter and while limiting cleaning head manufacturing costs.
[0017] De plus, la présence de la surface d’appui, prévue sur la face inférieure de la semelle, permet d’assurer, lors d’une opération de nettoyage d’une surface à nettoyer, un plaquage d’au moins une portion de la partie périphérique de la serpillère qui est située en regard de la face inférieure de la semelle contre la surface à nettoyer. Un tel plaquage confère des performances de nettoyage accrues à la tête de nettoyage selon la présente invention bien qu’une partie importante de la serpillère ne soit pas recouverte par le support de serpillère. [0018] La tête de nettoyage peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison. [0017] In addition, the presence of the support surface, provided on the underside of the sole, makes it possible to ensure, during a cleaning operation of a surface to be cleaned, a plating of at least one portion of the peripheral part of the mop which is located opposite the underside of the sole against the surface to be cleaned. Such plating confers increased cleaning performance on the cleaning head according to the present invention although a significant part of the mop is not covered by the mop support. [0018] The cleaning head may also have one or more of the following characteristics, taken alone or in combination.
[0019] De façon avantageuse, la zone d’appui s’étend sensiblement horizontalement lorsque la serpillère repose sur une surface horizontale. Une telle configuration de la zone d’appui facilite encore le retrait de la serpillère du support de serpillère. [0019] Advantageously, the support zone extends substantially horizontally when the mop rests on a horizontal surface. Such a configuration of the support area makes it even easier to remove the mop from the mop holder.
[0020] Selon un mode de réalisation de l’invention, la distance de dépassement est mesurée selon une direction radiale par rapport à un axe central du support de serpillère et lorsque la serpillère et le support de serpillère sont centrés l’un par rapport à l’autre. De façon avantageuse, la distance de dépassement est mesurée lorsque la serpillère est neuve et sèche.

[0062] Le corps principal 4 comporte des éléments de roulement 9, tels que des roulettes et/ou des galets de roulement, faisant saillie de la face inférieure 7 de la semelle 6 et configurés pour rouler sur la surface à nettoyer. De façon avantageuse, les éléments de roulement 9 sont montés libres en rotation par rapport au corps principal 4. [0062] The main body 4 comprises rolling elements 9, such as rollers and/or running rollers, projecting from the underside 7 of the sole 6 and configured to roll on the surface to be cleaned. Advantageously, the rolling elements 9 are mounted free to rotate relative to the main body 4.
[0063] Les éléments de roulement 9 peuvent par exemple comporter deux roulettes disposées sur une partie avant de la semelle 6 et par exemple entre le bord avant 4.1 du corps principal 4 et un bord avant du canal d’aspiration 8, et un galet de roulement situé à proximité du bord arrière 4.2 du corps principal 4. [0063] The rolling elements 9 can for example comprise two rollers arranged on a front part of the sole 6 and for example between the front edge 4.1 of the main body 4 and a front edge of the suction channel 8, and a roller of bearing located close to the rear edge 4.2 of the main body 4.
[0064] La tête de nettoyage 2 comprend de plus un dispositif de nettoyage humide 10 fixé au corps principal 4, et plus particulièrement à la semelle 6. The cleaning head 2 further comprises a wet cleaning device 10 fixed to the main body 4, and more particularly to the sole 6.
[0065] Le dispositif de nettoyage humide 10 comporte un support de serpillère 11 qui s’étend majoritairement ou intégralement sous la semelle 6, et une serpillère 12 qui est configurée pour être en contact avec la surface à nettoyer et qui est fixée de manière amovible à une surface inférieure 11.1 du support de serpillère 11. [0065] The wet cleaning device 10 comprises a mop support 11 which extends mainly or entirely under the sole 6, and a mop 12 which is configured to be in contact with the surface to be cleaned and which is removably fixed to a lower surface 11.1 of the mop holder 11.
[0066] Selon le mode de réalisation représenté sur les figures, le dispositif de nettoyage humide 10 comporte en outre un support de serpillère additionnel 11’ qui s’étend majoritairement ou intégralement sous la semelle 6, et une serpillère additionnelle 12’ qui est configurée pour être en contact avec la surface à nettoyer et qui est fixée de manière amovible à une surface inférieure 11.1’ du support de serpillère additionnel 11’. De façon avantageuse, le support de serpillère 11 et le support de serpillère additionnel 11 ’ sont disposés l’un à côté de l’autre. [0066] According to the embodiment shown in the figures, the wet cleaning device 10 further comprises an additional mop support 11' which extends mainly or entirely under the sole 6, and an additional mop 12' which is configured to be in contact with the surface to be cleaned and which is removably fixed to a lower surface 11.1' of the additional mop support 11'. Advantageously, the mop holder 11 and the additional mop holder 11' are arranged next to each other.
[0067] Cependant, selon une variante de réalisation de l’invention non représentée sur les figures, le dispositif de nettoyage humide 10 pourrait être dépourvu du support de serpillère additionnel 11’ et de la serpillère additionnelle 12’ . [0067] However, according to an alternative embodiment of the invention not shown in the figures, the wet cleaning device 10 could be devoid of the additional mop support 11 'and the additional mop 12'.
[0068] Le support de serpillère additionnel 11 ’ et la serpillère additionnelle 12’ ne seront pas décrits en détails ci-après puisque le support de serpillère additionnel 11 ’ et la serpillère additionnelle 12’ sont respectivement identiques au support de serpillère 11 et à la serpillère 12. Dans les dessins annexés, les éléments relatifs au support de serpillère additionnel 11 ’ auront les mêmes références numériques que les éléments correspondants relatifs au support de serpillère 11 mais seront suivis par une apostrophe. Il en est de même pour les éléments relatifs à la serpillère additionnelle 12’. The additional mop support 11' and the additional mop 12' will not be described in detail below since the additional mop support 11' and the additional mop 12' are respectively identical to the mop support 11 and to the mop 12. In the accompanying drawings, the elements relating to the additional mop support 11' will have the same reference numerals as the corresponding elements relating to the mop support 11 but will be followed by an apostrophe. The same is true for the elements relating to the additional 12' mop.
[0069] Comme montré sur les figures 3 et 5, le support de serpillère 11 est situé entre le canal d’aspiration 8 et le bord arrière 4.2 du corps principal 4, et présente une forme générale de plaque. De façon avantageuse, la serpillère 12 et le support de serpillère 11 s’étendent sensiblement parallèlement l’un par rapport à l’autre, et sensiblement horizontalement lorsque la serpillère 12 repose sur une surface horizontale. As shown in Figures 3 and 5, the mop holder 11 is located between the suction channel 8 and the rear edge 4.2 of the main body 4, and has the general shape of a plate. Advantageously, the mop 12 and the mop support 11 extend substantially parallel to each other, and substantially horizontally when the mop 12 rests on a horizontal surface.
[0070] Selon le mode de réalisation représenté sur les figures, le support de serpillère 11 et la serpillère 12 sont chacun circulaires et sont configurés pour être disposés de manière coaxiale. De façon avantageuse, la serpillère 12 présente un diamètre externe qui est supérieur au diamètre externe du support de serpillère 11. Toutefois, selon une variante de réalisation de l’invention non représentée sur les figures, le support de serpillère 11 et la serpillère 12 pourraient avoir une toute autre forme, par exemple carré, ovale ou rectangulaire) According to the embodiment shown in the figures, the mop support 11 and the mop 12 are each circular and are configured to be arranged coaxially. Advantageously, the mop 12 has an outer diameter which is greater than the outer diameter of the mop support 11. However, according to an alternative embodiment of the invention not shown in the figures, the mop support 11 and the mop 12 could have any other shape, for example square, oval or rectangular)
[0071] La serpillère 12 comporte plus particulièrement une partie centrale 12.1 qui est fixée de manière amovible au support de serpillère 11 par exemple par l’intermédiaire d’un système de fixation à boucles et crochets, et une partie périphérique 12.2 qui est annulaire et qui s’étend sur tout le pourtour de la partie centrale 12.1. De façon avantageuse, la partie périphérique 12.2 dépasse d’un bord périphérique du support de serpillère 11. En d’autres termes, la partie périphérique 12.2 s’étend au-delà du bord périphérique du support de serpillère 11 . The mop 12 more particularly comprises a central part 12.1 which is removably fixed to the mop support 11, for example by means of a hook and loop fastening system, and a peripheral part 12.2 which is annular and which extends over the entire circumference of the central part 12.1. Advantageously, the peripheral part 12.2 protrudes from a peripheral edge of the mop support 11. In other words, the part peripheral 12.2 extends beyond the peripheral edge of the mop support 11 .
[0072] Comme montré plus particulièrement sur les figures 2 et 4, la serpillère 12 fait saillie latéralement par rapport à un bord latéral 4.3 du corps principal 4 d’une distance de dépassement Dd comprise entre 10 et 30 mm, et par exemple comprise entre 10 et 20 mm. En outre, le support de serpillère 11 est situé en retrait du bord latéral 4.3 du corps principal 4 ou dépasse du bord latéral 4.3 d’une distance de saillie inférieure ou égale à 5 mm. Il convient d’être noté que la distance de dépassement Dd est mesurée selon une direction radiale par rapport à un axe central A du support de serpillère 11 , et la distance de saillie est mesurée selon une direction radiale par rapport à l’axe central A du support de serpillère 11 . As shown more particularly in Figures 2 and 4, the mop 12 projects laterally relative to a side edge 4.3 of the main body 4 by an overrun distance Dd between 10 and 30 mm, and for example between 10 and 20mm. In addition, the mop holder 11 is set back from the side edge 4.3 of the main body 4 or protrudes from the side edge 4.3 by a projection distance less than or equal to 5 mm. It should be noted that the overrun distance Dd is measured in a radial direction with respect to a central axis A of the mop holder 11, and the projection distance is measured in a radial direction with respect to the central axis A of the mop holder 11 .
[0073] En particulier, la portion de la serpillère 12 qui dépasse du bord latéral 4.3 du corps principal 4 forme une zone d’appui 13 qui s’étend sensiblement horizontalement lorsque la serpillère 12 repose sur une surface horizontale et qui est configurée pour permettre à un utilisateur d’exercer une force d’appui sur ladite zone d’appui 13 avec son pied. [0073] In particular, the portion of the mop 12 which protrudes from the side edge 4.3 of the main body 4 forms a support zone 13 which extends substantially horizontally when the mop 12 rests on a horizontal surface and which is configured to allow a user to exert a bearing force on said bearing zone 13 with his foot.
[0074] De façon similaire, la serpillère additionnelle 12’ fait saillie latéralement par rapport à un bord latéral 4.4 du corps principal 4 d’une distance de dépassement Dd’ comprise entre 10 et 30 mm, et par exemple comprise entre 10 et 20 mm. En outre, le support de serpillère additionnel 11 ’ est situé en retrait du bord latéral 4.4 du corps principal 4 ou dépasse du bord latéral 4.4 d’une distance de saillie inférieure ou égale à 5 mm. [0074] Similarly, the additional mop 12' projects laterally with respect to a side edge 4.4 of the main body 4 by an overrun distance Dd' of between 10 and 30 mm, and for example of between 10 and 20 mm. . In addition, the additional mop support 11′ is set back from the side edge 4.4 of the main body 4 or protrudes from the side edge 4.4 by a projection distance less than or equal to 5 mm.
[0075] Selon un mode de réalisation de l’invention, la serpillère 12 s’étend au- delà du bord périphérique du support de serpillère 11 d’une distance radiale de dépassement, et la distance radiale entre le support de serpillère 11 et le support de serpillère additionnel 11 ’ est sensiblement égale ou supérieure au double de la distance radiale de dépassement. De façon avantageuse, la distance radiale de dépassement est comprise entre 10 et 70 mm, et préférentiellement entre 20 et 60 mm. Autrement dit, l’entraxe entre les axes de rotations du support de serpillère et du support de serpillère additionnel est égal au premier diamètre externe du support de serpillère majoré de 10 à 70 mm, de préférence de 20 à 60 mm. According to one embodiment of the invention, the mop 12 extends beyond the peripheral edge of the mop support 11 by a radial overrun distance, and the radial distance between the mop support 11 and the additional mop support 11' is substantially equal to or greater than twice the radial overrun distance. Advantageously, the radial overrun distance is between 10 and 70 mm, and preferably between 20 and 60mm. In other words, the center distance between the axes of rotation of the mop support and of the additional mop support is equal to the first outer diameter of the mop support increased by 10 to 70 mm, preferably by 20 to 60 mm.
[0076] Selon le mode de réalisation représenté sur les figures, la semelle 6 comporte une cavité de réception 14 débouchant dans la face inférieure 7 de la semelle 6, et le support de serpillère 11 est reçu au moins partiellement dans la cavité de réception 14. La cavité de réception 14 comprend plus particulièrement une paroi de fond 14.1 qui est sensiblement plane et qui est située en retrait de la face inférieure 7 de la semelle 6, et une paroi circonférentielle 14.2 s’étendant au moins en partie autour du support de serpillère 11 . De façon avantageuse, la cavité de réception 14 présente une forme globalement circulaire et débouche dans le bord latéral 4.3 du corps principal 4. According to the embodiment shown in the figures, the sole 6 comprises a receiving cavity 14 opening into the lower face 7 of the sole 6, and the mop support 11 is received at least partially in the receiving cavity 14 The receiving cavity 14 more particularly comprises a bottom wall 14.1 which is substantially planar and which is set back from the lower face 7 of the sole 6, and a circumferential wall 14.2 extending at least partly around the support of mop 11 . Advantageously, the receiving cavity 14 has a generally circular shape and opens into the side edge 4.3 of the main body 4.
[0077] Comme montré plus particulièrement sur la figure 5, la surface inférieure 11.1 du support de serpillère 11 est décalée par rapport à la face inférieure 7 de la semelle 6 selon une direction de décalage, qui est sensiblement verticale lorsque la serpillère 12 repose sur une surface horizontale, et d’une distance de décalage inférieure ou égale à 2 mm, et par exemple d’environ 1 mm. De façon avantageuse, la distance de décalage est inférieure à l’épaisseur de la serpillère 12. As shown more particularly in Figure 5, the lower surface 11.1 of the mop support 11 is offset with respect to the lower face 7 of the sole 6 in an offset direction, which is substantially vertical when the mop 12 rests on a horizontal surface, and with an offset distance of less than or equal to 2 mm, and for example of around 1 mm. Advantageously, the offset distance is less than the thickness of the mop 12.
[0078] Selon le mode de réalisation représenté sur les figures, la face inférieure 7 de la semelle 6 est située légèrement en retrait de la surface inférieure 11.1 du support de serpillère 11. Toutefois, selon une variante de réalisation de l’invention, la surface inférieure 11.1 du support de serpillère 11 pourrait être située légèrement en retrait de la face inférieure 7 de la semelle 6. According to the embodiment shown in the figures, the lower face 7 of the sole 6 is located slightly set back from the lower surface 11.1 of the mop support 11. However, according to a variant embodiment of the invention, the lower surface 11.1 of the mop support 11 could be located slightly set back from the lower face 7 of the sole 6.
[0079] Comme montré plus particulièrement sur les figures 3 et 5, la face inférieure 7 de la semelle 6 comporte une surface d’appui 15 configurée pour exercer une force d’appui sur sensiblement toute la portion de la partie périphérique 12.2 de la serpillère 12 qui est située en regard de la face inférieure 7 de la semelle 6 lorsque la serpillère 12 repose sur une surface à nettoyer. De façon avantageuse, la surface d’appui 15 s’étend au moins en partie entre le support de serpillère 11 et le support de serpillère additionnel 11 ’. La surface inférieure 11.1 du support de serpillère 11 est plus particulièrement décalée par rapport à la surface d’appui 15 selon la direction de décalage et d’une distance correspondant à la distance de décalage. As shown more particularly in Figures 3 and 5, the underside 7 of the sole 6 comprises a bearing surface 15 configured to exert a bearing force on substantially the entire portion of the peripheral part 12.2 of the mop 12 which is located opposite the underside 7 of the sole 6 when the mop 12 rests on a surface to be cleaned. Advantageously, the bearing surface 15 extends at least in part between the mop support 11 and the additional mop support 11'. The lower surface 11.1 of the mop support 11 is more particularly offset with respect to the support surface 15 in the offset direction and by a distance corresponding to the offset distance.
[0080] Selon le mode de réalisation représenté sur les figures, la surface d’appui[0080] According to the embodiment shown in the figures, the bearing surface
15 est sensiblement parallèle à la paroi de fond 14.1 , et la paroi de fond 14.1 est située en retrait de la surface d’appui 15. Comme montré sur la figure 4, la paroi circonférentielle 14.2 est circulaire et s’étend autour d’au moins la moitié de la circonférence du support de serpillère 11 qui est circulaire, c’est-à-dire présente une forme en arc de cercle ayant un angle d’au moins d’au moins 180°, et par exemple autour d’au moins les trois quarts de la circonférence du support de serpillère 11 , c’est-à-dire présente une forme en arc de cercle ayant un angle d’au moins d’au moins 270°. 15 is substantially parallel to the bottom wall 14.1, and the bottom wall 14.1 is set back from the bearing surface 15. As shown in Figure 4, the circumferential wall 14.2 is circular and extends around at least half of the circumference of the mop support 11 which is circular, that is to say has the shape of an arc of a circle having an angle of at least at least 180°, and for example around at least less than three quarters of the circumference of the mop support 11, that is to say has an arcuate shape having an angle of at least at least 270°.
[0081] Selon le mode de réalisation représenté sur les figures, le support de serpillère 11 est monté mobile en rotation par rapport au corps principal 4 autour d’un axe de rotation qui est confondu avec l’axe central A du support de serpillère 11 , et la tête de nettoyage 2 comporte un mécanisme d’entraînement en rotationAccording to the embodiment shown in the figures, the mop support 11 is mounted so as to be able to rotate relative to the main body 4 around an axis of rotation which coincides with the central axis A of the mop support 11 , and the cleaning head 2 comprises a rotary drive mechanism
16 configuré pour entraîner en rotation le support de serpillère 11. Un tel mécanisme d’entraînement en rotation 16 est bien connu de l’homme du métier et n’est donc pas décrit plus en détails ci-après. 16 configured to drive the mop holder 11 in rotation. Such a rotation drive mechanism 16 is well known to those skilled in the art and is therefore not described in more detail below.
[0082] Le dispositif de nettoyage humide 10 comporte en outre un réservoir de liquide de nettoyage 17 qui est situé dans une partie supérieure du corps principal 4, et un circuit de distribution de fluide (non représenté sur les figures) relié fluidiquement au réservoir de liquide de nettoyage 17 et configuré pour alimenter la serpillère 12 et la serpillère additionnelle 12’ en liquide de nettoyage. Le réservoir de liquide de nettoyage 17 peut par exemple être monté de manière amovible sur le corps principal 4. [0083] Le dispositif de nettoyage humide 10 peut comporter également un organe d’actionnement, tel qu’une pédale d’actionnement, qui est configuré pour être actionné par un utilisateur, par exemple avec un pied de l’utilisateur, et qui est monté mobile sur une partie supérieure du corps principal 4 entre au moins une première position d’actionnement dans laquelle l’organe d’actionnement est configuré pour actionner un arrêt de l’alimentation de la serpillère 12 et de la serpillère additionnelle 12’ en liquide de nettoyage et une deuxième position d’actionnement dans laquelle l’organe d’actionnement est configuré pour actionner une alimentation de la serpillère 12 et de la serpillère additionnelle 12’ en liquide de nettoyage. Toutefois, selon une variante de réalisation de l’invention, l’organe d’actionnement pourrait être prévu sur une poignée de préhension de l’appareil de nettoyage domestique. [0082] The wet cleaning device 10 further comprises a reservoir of cleaning liquid 17 which is located in an upper part of the main body 4, and a fluid distribution circuit (not shown in the figures) fluidically connected to the reservoir of cleaning liquid 17 and configured to supply the mop 12 and the additional mop 12' with cleaning liquid. The cleaning liquid tank 17 can for example be removably mounted on the main body 4. [0083] The wet cleaning device 10 may also comprise an actuating member, such as an actuating pedal, which is configured to be actuated by a user, for example with the user's foot, and which is movably mounted on an upper part of the main body 4 between at least a first actuating position in which the actuating member is configured to actuate a stoppage of the supply of the mop 12 and of the additional mop 12' in liquid cleaning liquid and a second actuating position in which the actuating member is configured to actuate a supply of the mop 12 and of the additional mop 12' with cleaning liquid. However, according to a variant embodiment of the invention, the actuating member could be provided on a handle for gripping the household cleaning appliance.
[0084] Un procédé de retrait de la serpillère 12 du support de serpillère 11 afin de procéder à un nettoyage de la serpillère 12 ou à un remplacement de cette dernière est représenté sur les figures 6 à 8. A method of removing the mop 12 from the mop holder 11 in order to clean the mop 12 or replace the latter is shown in Figures 6 to 8.
[0085] Un tel procédé comprend une première étape (voir la figure 6) consistant à exercer une force d’appui sur la zone d’appui 13 à l’aide d’un pied, une deuxième étape (voir la figure 7) consistant à soulever le corps principal 4, par exemple à l’aide d’un tube d’aspiration relié au manchon de raccordement 3, tout en maintenant le pied sur la zone d’appui 13, et une troisième étape (voir la figure 8) consistant à reposer le corps principal 4 sur le sol. [0085] Such a method comprises a first step (see FIG. 6) consisting in exerting a pressing force on the pressing zone 13 using a foot, a second step (see FIG. 7) consisting to lift the main body 4, for example using a suction tube connected to the connection sleeve 3, while maintaining the foot on the support zone 13, and a third step (see Figure 8) consisting in resting the main body 4 on the ground.
[0086] Ainsi, la zone d’appui 13, qui est formée par la portion de la serpillère 12 qui dépasse du bord latéral 4.3 du corps principal 4, permet un retrait aisé et rapide de la serpillère 12 du support de serpillère 11 sans nécessiter en particulier un retournement de la tête de nettoyage 2 qui serait susceptible d’entraîner d’une part une chute de la tête de nettoyage 2 et donc une dégradation de cette dernière, et d’autre part d’entraîner une fuite d’eau sale résiduelle contenue dans la tête de nettoyage 2 et ainsi une salissure du sol venant d’être nettoyé. [0087] De plus, compte tenu du fait que la serpillère 12 peut être aisément retirée du support de serpillère 11, les risques qu’un utilisateur laisse, après une opération de nettoyage, la serpillère 12 et la serpillère additionnelle 12’, sales et humides, sur la tête de nettoyage 2 sont fortement réduits. [0088] Selon un mode de réalisation de l’invention non représenté sur les figures, la serpillière 12 pourrait dépasser du bord avant ou du bord arrière du corps principal 4 de ladite distance de dépassement Dd. [0086] Thus, the support zone 13, which is formed by the portion of the mop 12 which protrudes from the side edge 4.3 of the main body 4, allows easy and quick removal of the mop 12 from the mop support 11 without requiring in particular a reversal of the cleaning head 2 which would be likely to cause on the one hand a fall of the cleaning head 2 and therefore a deterioration of the latter, and on the other hand to cause a leak of dirty water residual contained in the cleaning head 2 and thus soiling of the floor which has just been cleaned. Furthermore, given the fact that the mop 12 can be easily removed from the mop support 11, the risks of a user leaving, after a cleaning operation, the mop 12 and the additional mop 12', dirty and wet, on cleaning head 2 are greatly reduced. According to an embodiment of the invention not shown in the figures, the mop 12 could protrude from the front edge or from the rear edge of the main body 4 by said overrun distance Dd.
[0089] Selon un autre mode de réalisation de l’invention non représenté sur les figures, la tête de nettoyage 2 pourrait être raccordée à un manche de préhension d’un appareil de nettoyage domestique, et être dépourvue de canal d’aspiration. [0089] According to another embodiment of the invention not shown in the figures, the cleaning head 2 could be connected to a gripping handle of a household cleaning appliance, and be devoid of a suction channel.
[0090] Selon encore un autre mode de réalisation de l’invention non représenté sur les figures, la serpillère 12 pourrait être montée vibrante par rapport au corps principal 4 ou encore être passive. [0091] Bien entendu, la présente invention n’est nullement limitée au mode de réalisation décrit et illustré qui n’a été donné qu’à titre d’exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d’équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. According to yet another embodiment of the invention not shown in the figures, the mop 12 could be mounted vibrating with respect to the main body 4 or even be passive. Of course, the present invention is in no way limited to the embodiment described and illustrated which has been given by way of example only. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
