Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] With reference to the appended drawings, below follows a more detailed description of embodiments of the invention cited as examples.

[0015] In the drawings:

[0016] FIG. 1 is a schematic view of a thermal unit of a vehicle that could be use with vacuum cleaner of the invention, and

[0017] FIG. 2 is a schematic view of a vacuum cleaner according to the invention.

DETAILED DESCRIPTION

[0018] In reference to FIG. 1, a thermal unit 10 of vehicle can typically include a fan 11, a heater 12 and a cooler 13. By means of the fan 11, outside air can be sucked in a channel 14, can enter the thermal unit 10 and pass through the heater 12 and the cooler 13. Therefore, the thermal unit 10 can provide a heated or cooled air flow F which will be directed towards the user compartment of the vehicle. In practice, the heater 12 can be a radiator, and the cooler 13 can be an evaporator forming part of a refrigerant circuit of an air conditioning system. Such a refrigerant circuit typically carries a refrigerant in a loop through a compressor, a condenser, an expander and an evaporator capable of cooling an air flow directed towards the user compartment.

[0019] The thermal control system 10 also comprises air circuits connected to the thermal unit 10 and designed to carry some of the air flow towards various locations in the cabin and to blow it inside the user compartment.

[0020] FIG. 1 shows one air circuit 15 which has an inlet 16 connected to the thermal unit 10 and two outlets 17, 18 through which an air sub flow is blown towards the user compartment. The outlets may be located near each one of the cabin side walls. More specifically, the air circuit 15 can include: [0021] a first duct 15a having a first outlet 17 which opens towards driver seat, for blowing air towards the driver's torso; [0022] and a second duct 15b having a second outlet 18 which opens towards the passenger seat, for blowing air towards the passenger's torso;

[0023] the first and second ducts 15a, 15b being connected to the same inlet 16.

[0024] Part of the air blown through outlets 17, 18 could also be directed towards the corresponding adjacent side wall. Although this is not illustrated, the air circuit 15 could be provided with more ducts and/or more outlets.

[0025] In FIG. 2, The thermal control system 1 may comprise other air circuits (not shown), such as: an air conduit for blowing air towards the windscreen and/or the head of the cabin occupant(s); an air conduit for blowing air towards the feet of the cabin occupant(s) and/or the area located along the lower part of the side walls.

[0026] With reference to FIG. 2, portable vacuum cleaner 2 according to the invention comprises a connecting device 20 to the external air duct 14 of the vehicle thermal control system 1. The portable vacuum cleaner 2 also comprises a flexible hose 21 connected to the connection device and the other end of which is equipped with a suction head 24.

[0027] The portable vacuum cleaner 2 according to the invention also comprises a dust collection tray 22 mounted on the flexible hose 21. The dust collection tray 22 may comprise a dust filter 23. The dust filter 23 is, for example, removably mounted in dust tray 22 The dust tray 22 is, for example, removably mounted on the flexible hose 21. For this purpose, the hose 21 and the dust container comprise connecting elements for maintaining an airtight seal between the hose 21 and the dust container 22. For example, the connecting elements comprise a sleeve mounted on the hose 21 and a hole in the dust container 22. The sleeve is then pressed into the dust container opening 22. A seal may be present in the dust container opening 22 to ensure a seal between the hose sleeve 21 and the dust container 22.

[0028] The connection device 20 of portable vacuum cleaner 2 according to the invention may comprise locking elements for holding on portable vacuum cleaner 2 upstream of the fan 11 of the thermal control device 1. The locking elements also allow the Vacuum cleaner 2 to be disengaged from the thermal control device 1 when vacuum cleaner 2 is no longer in use.

[0029] It is to be understood that the present invention is not limited to the embodiments described above and illustrated in the drawings; rather, the skilled person will recognize that many changes and modifications may be made within the scope of the appended claims.
