Description
Technical Field
The invention relates more particularly to a ski-type household vacuum cleaner which allows the suction of small particle size dust and waste present on a surface to be cleaned, which may be, for example, a tile floor, a laminate, a felt or a carpet.
In this specification, a ski-type vacuum cleaner or suction assembly refers to a vacuum cleaner or suction assembly that can be displaced rolling on the floor surface, for example by means of wheels or casters, when the vacuum cleaner is in use. In a ski-type vacuum cleaner, the suction nozzle is connected to the suction assembly by a suction tube comprising a rigid portion and a flexible portion. During a cleaning operation, a user of the ski-type vacuum cleaner grips the suction nozzle via a handle provided on or integral with the rigid portion of the suction tube. Ski cleaners are typically pulled by the user through the handle and flexible portion of the suction tube, a pattern of displacement which is the source of the name "ski cleaner". Ski cleaners or ski suction assemblies also include those with motorized wheels or casters and which are capable of tracking the displacement of the suction nozzle, handle or user.
Background
Document EP3409171 discloses an inhalation assembly comprising: a vacuum cleaner housing; a suction end part through which external air can be sucked by the suction assembly; at least one vent through which air cleaned by the inhalation assembly may exit the inhalation assembly; a pneumatic circuit extending between the suction end piece and the at least one exhaust vent; a suction unit disposed on the pneumatic circuit, the suction unit including an electric motor and a ventilator coupled to the electric motor to generate an air flow in the pneumatic circuit from a suction end piece to at least one exhaust vent; and a waste separating and collecting device disposed on the pneumatic circuit upstream of the suction unit and through which the air flow generated by the ventilator passes when the suction assembly is in operation, the waste separating and collecting device being removably mounted with respect to the cleaner housing.
The waste separating and collecting device comprises, inter alia: a waste collection bowl comprising a waste collection container; a grip handle hingedly mounted on the waste collection bowl between a locked position and an unlocked position; and two locking members carried by the gripping handles. The waste separating and collecting device is more particularly configured such that when the gripping handle occupies the locked position, the two locking members cooperate with complementary locking elements provided on the cleaner housing to lock the waste separating and collecting device to the cleaner housing, and such that when the gripping handle occupies the unlocked position, the two locking members release the locking elements to permit removal of the waste separating and collecting device from the cleaner housing.
The gripping handle described in document EP3409171 is hingedly mounted on the waste collection bowl by means of two pivoting links and thus forms a gripping handle.
This configuration of the grip handle does not allow for emptying of waste contained in the waste collection container with one hand. In fact, waste evacuation requires tilting the waste collection container so that its waste evacuation opening is oriented downward. In a handle configuration with an articulated handle, the hand holding the handle cannot be used to tilt the waste collection container because the gripping area of the handle does not provide an ergonomic position to allow the hand to tilt the waste collection container so that its waste drain opening is oriented downward. In fact, when an attempt is made to apply a rotational torque to the handle, the hand tends to rotate around the cylindrical gripping area due to the weight of the waste collection container and the force of the lever arm that needs to be applied. Furthermore, in the handle construction with hinged handles as described in document EP3409171, the handles face the waste drain opening, and therefore the handles need to be folded back to disengage the handles from the waste drain opening. Thus, in a handle configuration with an articulated handle, a second hand is required to lift the rear of the waste collection container in order to empty its contents into, for example, a dustbin. A central handle with a gripping surface extending in the middle plane of the waste collection container provides the advantage that the waste collection container can be gripped and emptied with one hand. However, no central handle is known which allows the waste separating and collecting device to be effectively locked to the cleaner housing.
Disclosure of Invention
The present invention aims to overcome all or part of these disadvantages.
The technical problem underlying the present invention is, inter alia, to provide a suction assembly which allows to ensure an effective locking of a waste collection bowl on a cleaner housing of the suction assembly and to ensure an easy, firm and stable manual grip of the waste collection bowl, while maintaining a satisfactory accessibility of the waste collection bowl.
To this end, the present invention relates to an inhalation assembly, such as a ski type inhalation assembly, comprising:
-a cleaner housing;
-a suction end piece through which external air can be sucked by the suction assembly;
-at least one vent through which air cleaned by the inhalation assembly may leave the inhalation assembly;
-a pneumatic circuit extending between the suction end piece and the at least one exhaust hole;
-a suction unit arranged on the pneumatic circuit, the suction unit comprising an electric motor and a ventilator coupled to the electric motor for generating an air flow in the pneumatic circuit from a suction end piece to at least one exhaust hole; and

-a waste collection bowl comprising a waste collection container;
-a waste separation device at least partially disposed in the waste collection container;
-a gripping handle for removing the waste separating and collecting device from the cleaner housing, the gripping handle being movably mounted relative to the waste collection bowl between a first handle position and a second handle position; and
-two locking members movably mounted between a locking position, in which the locking members are configured to cooperate with the cleaner housing for locking the waste separating and collecting device to the cleaner housing, and an unlocking position; in the unlocked position, the locking member is configured to release the cleaner housing so as to permit removal of the waste separation and collection device from the cleaner housing, the grip handle being configured to cause displacement of the locking member between the locked position and the unlocked position when the grip handle is displaced between the first handle position and the second handle position.
The gripping handle is elongate in shape and comprises a gripping portion configured to be manipulated by a user and extending substantially in a central longitudinal plane of the waste collection bowl, locking members are provided on both sides of the gripping portion, and the gripping handle is hingedly mounted on the waste collection bowl by means of a pivot link defining a pivot axis in the vicinity of a single one of the ends of the gripping handle.
Advantageously, the grip portion is configured to extend in a mid-longitudinal plane of the waste collection bowl regardless of the position occupied by the grip handle between the first and second handle positions.
This central arrangement of the grip handle, in combination with the articulation of the grip handle in a single one of the ends of the grip handle, ensures easy, firm and stable manual gripping of the waste collection bowl as it is removed from the cleaner housing, and thus greatly facilitates emptying of the waste contained in the waste collection container. This arrangement also allows the gripping handle to be grasped with one hand, the locking member to be unlocked, the waste collection bowl to be removed and tilted for emptying thereof.
Furthermore, the provision of locking members on both sides of the gripping portion also ensures effective locking of the waste collection bowl on the cleaner housing when the locking members occupy the locked position.
The inhalation assembly may also have one or more of the following features, alone or in combination.
According to one embodiment of the invention, the pivot axis is adjacent to and, for example, at a single one of the ends of the grip handle.
