This patent application claims priority from Italian patent application no. 102020000015769 filed on 30 Jun. 2020, the entire disclosure of which is incorporated herein by reference.
This invention relates to a cab for a heavy-duty vehicle, in particular a cab for a land vehicle, such as a truck, comprising a sanitization system.
It is usual for companies transporting goods or heavy equipment to have fleets of vehicles that are used interchangeably by different drivers depending on the job assigned to them.
The current health emergency, due to the SARS-COV-2 pandemic, has made the need to sanitize the cabs of heavy vehicles, such as trucks that may be used by different drivers as in the above example, topical.
However, current sanitizing methods involve manual sanitizing of the cabs of such vehicles, which wastes time and sanitizing products and consequently adds to costs. In addition, users engaged in this sanitization practice, who are often the same drivers who are required to disinfect the seat at the end of their shift, are exposed to the use of potentially hazardous chemicals.
Clearly, when the sanitizing operation is currently carried out manually, there is a risk of not performing optimal sanitization due to the intrinsic quality of the sanitization linked to the action of the operator, who may forget to sanitize some parts or sanitize them in a careless fashion, putting the health of the driver, who will be called to take over, at risk.
There is a need, therefore, to optimally sanitise the cabs of heavy-duty vehicles without wasting time or increasing costs.
The purpose of this invention is to fulfil the above requirements in an optimal and economical manner.
The above-mentioned purpose is achieved with a vehicle comprising a sanitization system and a related method as claimed in the attached independent claims.
Additional, preferred embodiments of the invention are produced according to the dependent claims or the claims related to the above-mentioned independent claims.
In order to better understand this invention, a preferred embodiment thereof will now be described by way of non-limiting example and with reference to the accompanying drawings, in which:
In
As illustrated in
The cab 1 is carried by a vehicle frame, not illustrated, which is movable across the ground, as known, and therefore not further described for brevity.
According to the invention, the vehicle 2 comprises a sanitization system 3 configured to sanitize the housing 5 using fluid.
Advantageously, the sanitization system 3 is integrated within the walls 4 defining the housing 5.
As illustrated in greater detail in
Advantageously, the diffuser means 9 comprise a number of nebulization points 10 each fluidically connected to the fluid source 12 and, in the described embodiment, fluidically in series with each other.
According to the illustrated embodiment, referring to
Advantageously, each nebulization point 10 is guidable so that the position of the fluid that it nebulizes can vary spatially so as to reach each point of the cab 1.
Advantageously, each nebulization point 10 comprises a nozzle 11 configured to define a particular sanitizing fluid nebulization pattern. Each nozzle 11 can, preferably, be selectively mounted at the respective nebulization point 10.
These nozzles 11 may, preferably, be fixed-jet nozzles and may be replaced with nozzles of a size suitable for the size of the housing 5 or variable-jet nozzles configured to vary their flow rate according to an appropriate control signal.
The sanitizing fluid source 12 is preferably a tank 13, more preferably integrated within one of the walls 4, and provided with an opening 13a accessible from the outside to allow it to be filled, either directly, as in the illustrated example, or via a special duct, not illustrated.
The source 12 may advantageously be provided with level sensor means 14 configured to detect the level of sanitizing fluid contained within the tank 13.
The sanitizing fluid may be of any type suitable for sanitizing the housing 5, i.e. for eliminating pathogens such as viruses, bacteria, fungi and mould, such as, for example, hydrogen peroxide or any other known type of sanitizing fluid.
The sanitization system 3 further comprises pumping means 15 fluidically interposed between the source 12 and the diffuser means 9 configured to suck the sanitizing fluid from the tank 13 and to send it to the diffuser means 9. Advantageously, these pumping means 15 comprise an electric pump, powered at 12 V or 24 V depending on the power supply type of the vehicle 2. Optionally, the pumping means 15 may be provided with a special converter/inverter configured to vary the power supply voltage to the correct voltage for the type of pump installed.
The pumping means 15 are preferably configured to vary the pressure of the sanitizing fluid relative to the housing pressure within the tank 13.
The sanitization system 3 may comprise heating means 16 fluidically interposed between the pumping means 15 and the diffuser means 9 to heat the sanitizing fluid to a predetermined temperature, if required by the type of sanitizing fluid. Advantageously, these heating means 16 may comprise a heat exchanger, for example an electric one.
The sanitization system 3 may comprise sensor means 17 configured to detect the presence of people inside the housing 5. These sensor means 17 can, advantageously, comprise a volumetric sensor or a thermal video camera.
Optionally, the sensor means 17 may also be configured to allow the detection of the body temperature of the occupants by managing the tracking and acquisition of the daily data of the fleet manager with respect to risk indicators that may require sanitization at close time intervals.
The sanitization system 3 also comprises ventilation means 18 configured to selectively enable the fluidic communication of the housing 5 with the external environment. In the described embodiment, these ventilation means 18 comprise forced ventilation means 19 such as an electronically controlled fan, preferably when switched on or off, and when speed is controlled (air flow rate).
Advantageously, the sanitization system 3 comprises an electronic unit 20 electronically connected to the diffuser means 9, to the sensor means that the sanitization system 3 may be provided with, and to the ventilation means 18 and comprising processing means configured to receive an activation signal for the sanitization system 3 and to control, as a consequence, the operation of the diffuser means 9 and of the ventilation means 18, taking into account, when present, the sensor means described above.
In particular, the electronic unit 20 can be made separately or integrated into the vehicle 2 ECU.
The processing means are configured to store, or to receive as input, data relating to the size of the housing 5 and of the type of sanitizing fluid in order to calculate the quantity of the latter to be nebulized inside the housing 5.
Advantageously, the electronic unit 20 comprises telecommunication means configured to enable the remote control of the sanitization system 3, for example using a remote control, for example using vehicle fleet control software or, again, using a software application that can be installed on a smartphone.
Again, the electronic unit 20 may be electrically connected to a special button or screen function that can be selected by the user and activated once they have left the housing 5, a state that can be detected using the sensor means 17.
The operation of the embodiment of the sanitization system 3 described above is the following.
When the driver has finished their route and has exited the passenger compartment, they can activate the sanitization, as described above, using one of the remote/in-cab control systems for the sanitization system 3. This operation can also be carried out by a management plant for the vehicles 1, for example those parked in the fleet carpark.
Once the sanitization cycle has been activated, the electronic unit 20 activates a verification step to verify the operation of its elements, such as the pumping means 15, the ventilation device 18, or, if present, the heating means 16, or using the level sensor means 14, the verification of the presence of enough sanitizing fluid in the tank 13.
If an anomaly is detected, it is indicated using a light and/or sound indicator in the vehicle 2 and/or a remote management software/app notification.
If no anomalies are detected, the electronic unit 20, having stored data relating to the type of sanitizing fluid and the size of the housing 5, launches a fluid distribution step. This, therefore, controls the pumping means 15 so that they draw a predetermined quantity of sanitizing fluid from the source 12 and send it to the diffuser means 9 for dispersing it in the housing 5 using the nozzles 11.
If the latter are variable jet nozzles, the electronic unit 20 can adjust the opening so as to vary the nebulization thereof, according to a precise sanitizing fluid distribution cycle, depending on the size of the housing 5 and on the type of sanitizing fluid.
If it is necessary, based on the type of sanitizing fluid, to raise the temperature thereof before sending it to the diffuser means 9, the electronic unit 20 controls the heating means 16 so that they bring the sanitizing fluid to a predetermined temperature before nebulizing them using the diffuser means 9.
Once the fluid distribution cycle is complete, the electronic unit 20 checks that a predetermined time for allowing the sanitizing fluid to act has passed and checks the ventilation devices 18 so as to enable the gas residues of the nebulized fluid to escape into the environment and the housing 5 to be aired.
In the example described, the electronic unit 20 activates the forced ventilation means 19 so as to force the escape of the gas residues of the sanitizing fluid into the external environment and, thus, to air the housing 5.
In parallel to what is described above, the electronic unit 20 performs a continuous check that no living being enters inside the housing 5 using, for example, the sensor means 17 or by detecting the opening of the cab 1 doors. If this condition occurs, the sanitization is interrupted and the ventilation means 18 are immediately activated.
The electronic unit 20 can advantageously store the sanitization cycles successfully performed and communicate them to the remote management system by storing the date and time of the sanitization that took place.
In light of the above, it's clear that this invention also relates to a method of sanitizing a housing 5 for a vehicle 1 as described above and comprising the steps of:
The method also comprises an additional step, in parallel to those listed above, of verifying whether there is a living being inside the housing 5, if this is verified the sanitization is stopped and the ventilation means 18 are operated.
The anomaly check step comprises at least one of the following steps:
The fluid distribution step has a predetermined duration depending on the type of sanitizing fluid and on the dimensions of the housing 5 according to what is processed by the electronic unit 20. In particular, the electronic unit 20 can also control the orientation of the nebulization points 10, i.e. the nozzles 11, depending on the size and arrangement of the housing 5.
Similarly, the wait before activating the ventilation means 18 has a predetermined duration depending on the type of sanitizing fluid to eliminate the pathogens concerned.
The method can also comprise the step of storing the date and time of the housing 5 sanitization that has occurred.
The advantages of a vehicle 2 provided with a sanitization system 3 according to this invention are clear from the above.
Thanks to the sanitization system 3, it is possible to automate and reduce the sanitization time of the vehicular housing 5, making it possible to sanitize effectively and safely.
The automatic system consumes little energy and can be totally controlled remotely, checking the operation thereof and the history of activations.
In addition, the proposed system is independent of the vehicle type and sanitizing liquid, and can be easily applied by varying the supply time for the sanitizing liquid inside the housing.
In addition, it is possible to easily integrate the electronic unit with the other control systems for the vehicle or vehicle fleet, by making the latter more versatile.
Thanks to the use of nozzles 11 that can be separated, it is possible to easily replace the flow rate of the diffuser means 9 by modifying the capacity of the sanitization system 3 depending on different operational needs.
Finally, it is clear that the vehicle 2 provided with a sanitization system 3 according to this invention can be modified, and variations can be made thereof, without, however, departing from the scope of protection as set forth in the claims.
For example, it is clear that although a cab 1 is illustrated, it is possible to use the sanitization system 3 in any vehicle housing 5 that can be used by vehicle operators.
Again, the number of devices, shapes, and arrangements described here may vary as a function of the type of vehicle with which they are associated.
As disclosed in the description, some of the functional elements of the sanitization system 3 may be optional, like the corresponding steps of the corresponding control method.
