Description

technical field

[0001] The present invention relates to the field of handheld vacuum cleaners, and in particular to the assembly of handheld vacuum cleaners. Such vacuum cleaners generally have a modular assembly structure composed of various sub-assemblies designed to be assembled together during the assembly phase of the handheld vacuum cleaner. To this end, the vacuum cleaner generally comprises a first sub-assembly including a technical unit equipped with a motor assembly, and a second sub-assembly including a handle unit designed to be assembled to the technical unit. State of the art

[0002] EP3632284 B1 is a known technical unit for a portable vacuum cleaner, comprising a main body housing a motor assembly and designed to be assembled to a handle unit during the vacuum cleaner assembly phase. The handle unit includes a handle and a main housing for receiving the main body.

[0003] Such a technical block simplifies the manufacture of the vacuum cleaner since it is possible to manufacture two separate sub-assemblies of the vacuum cleaner independently, which can then be assembled together during the assembly of the vacuum cleaner.

[0004] However, the structure of the technical block and handle assembly of the EP3632284 B1 is complex, which negatively impacts the reliability and manufacturing cost of such components. A technical block for a handheld vacuum cleaner is known, for example, as KR-A-20190120569. Summary of the invention

[0005] The present invention aims to remedy these drawbacks.

[0006] The technical problem underlying the invention is to propose a technical block for a portable vacuum cleaner that is easy to assemble and offers reliability and a reduced cost for the portable vacuum cleaner.

[0007] To this end, the invention relates to a technical block for a portable vacuum cleaner comprising a main body housing a motor assembly. The technical block is configured so that, during the vacuum cleaner assembly phase, it is attached to a handle block comprising a handle and a housing for receiving the main body. According to the invention, the technical block also includes a human-machine interface positioned on an outer face of the main body, and this interface forms a guide rib designed to cooperate with a groove in the housing during the assembly phase.

[0008] Thanks to this invention, the technical unit integrates all electrical / electronic functions, including the display and suction functions, while the handle unit simply serves as a mechanical interface for connecting the various components of the handheld vacuum cleaner. This simplifies the handle unit's structure and improves the vacuum cleaner's reliability because, unlike the aforementioned prior art, it eliminates the need to power both components within the handle unit, such as the human-machine interface, and components within the technical unit, such as the suction motor. Furthermore, the human-machine interface serves both as an information transmission system for the user and as a guide / error-proofing system during the assembly of the technical unit and the handle unit. This simplifies vacuum cleaner assembly while reducing the cost and complexity of the technical unit.

[0017] This design allows all electrical and electronic functions to be grouped within the technical block, while the handle assembly simply serves as a mechanical interface for connecting the various components of the handheld vacuum cleaner. This simplifies the handle assembly's structure and improves the vacuum cleaner's reliability, as a separate electrical connection between the handle and the technical block is not required to power the motor. Furthermore, this grouping of electrical and electronic functions optimizes the vacuum cleaner's manufacturing cost.Furthermore, the technical unit allows for easy mounting on the handle assembly, as the main body is designed to fit into the designated slot. The support piece facilitates the integration of electrical cables into the handle and ensures the correct positioning of the power connector for connection to the vacuum cleaner's energy storage system, such as a battery. Additionally, the support piece ensures the initial electrical cables are securely held during transport of the technical unit and properly positioned during assembly.

[0034] This arrangement ensures the correct positioning of the cable support piece, and therefore the electrical cables within the handle, thus optimizing the assembly of the technical unit onto the handle assembly. It also prevents incorrect assembly that could lead to quality issues or even safety problems when using the vacuum cleaner.

[0035] According to an advantageous feature of the invention, the main body comprises an air diffusion nozzle and advantageously a filter positioned around the air diffusion nozzle.

[0036] Such an arrangement allows for optimized suction and in particular optimized air circulation while ensuring filtration of the air expelled from the vacuum cleaner.

[0037] According to an advantageous feature of the invention, the cable support piece is attached to the power connector solely by means of electrical cables extending between the cable support piece and the power connector.
