The flow chart for the in-car warm-air feed method that Fig. 2 provides for another embodiment of the invention.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
Referring to Fig. 1 and Fig. 2, the embodiments of the invention provide a kind of in-car warm-air feed method, wherein, including such as
Lower step：
Step S100, tail gas imported into the first water tank, because the waste gas that gives off has higher temperature, so as to right
Water in first water tank is heated.
Step S200, the first water valve of unlatching.
It should be noted that can include before step S200：
Step S110, judge whether there are heating demands in driver's cabin, if it is, into step S200；If it is not, then entering
Enter step S410.
Wherein, it can specifically judge whether to need to start heating by detecting the temperature in driver's cabin, or can also
Judge whether to need to start heating by the sendible temperature of occupant, in the present embodiment, the mode for starting heating is not limited.
Step S300, direct water into circulation heating is carried out in the heat-conducting plate in car body, wherein, heat-conducting plate is uniformly distributed in
In car body floor, to after heat-conducting plate heating, heat can be delivered on the pin of occupant through floor, simultaneously as heat-conducting plate is each
The temperature equalization at place, so as to which so that the air themperature in driver's cabin is also more balanced, it is any no matter the occupant in driving is sitting in
Uniform sendible temperature can be obtained on position, will not occur the air themperature in the prior art at the different distance of air channel
The problem of differing larger.
Whether step S400, detection occupant's foot temperature are less than the first set temperature value, wherein, first set temperature value
Depending on can be according to the comfort level of occupant underfooting at different temperatures, while also to ensure the heating demand in driver's cabin, at this
In embodiment, first set temperature value is 12 DEG C.
Step S410, if it is not, then close the first water valve, stop providing hot water into heat-conducting plate, to prevent temperature too high
And reduce the comfort level of occupant.
Wherein, step S400 also includes：
If it is, into step S110, so as to further choose whether that needs proceed heating.
Further, also include before step S300：
Step S201, the second water valve is led water to, to limit the flow of the water into heat-conducting plate, be lowered into heat conduction
The flow velocity of water in plate, it is ensured that the adequacy of heat exchange.
Further, also include after step S200：
Whether step S210, the supply water temperature for detecting the first water valve walk more than the second set temperature value if it is, entering
Rapid S220；If it is not, then into step S201.
Step S220, the water for providing the first water valve import the second water tank, to be cooled down, when water temperature is reduced to suitably
During temperature value, heat-conducting plate can be delivered to and carry out circulation heating.
Wherein, the second set temperature value can be set according to the actual conditions of in-car heat exchange, in the present embodiment, should
Second set temperature value is 60 DEG C.
Further, it can include after step S220：
Whether step S230, the temperature of the water detected in the second water tank are more than the second set temperature value, if it is not, then into
Step S201.
It is understood that the anti-icing fluid that adiabatic condensation temperature is less than -30 DEG C can be contained with the first water tank and the second water tank,
To play a part of reducing water temperature, specifically, because tail gas is introduced directly into the first water tank, the temperature liter in the first water tank can be made
Warm very fast, and the temperature of tail gas is higher, the water temperature in the first water tank is well over second temperature setting value, so that from the first water
The water temperature of case output is also easily higher than second temperature setting value, therefore sets anti-icing fluid to prevent the first water tank in the first water tank
In water temperature rise too fast too high, keep it within the scope of suitable temperature, and in order to avoid finally entering in heat-conducting plate
Water temperature over-high, can water enter heat-conducting plate before further be cooled down by the second water tank, it is possible to ensure finally it is defeated
Enter the temperature of water into heat-conducting plate not over the second set temperature value.
Further, also include before step S100：
Whether the water level in step S10, the first water tank of detection is less than setting height value, if it is, into step S100；
If it is not, then into step S11；
Step S11, the first water tank of cleaning.
It should be noted that filter screen is provided with the first water tank, and when tail gas is imported in the first water tank, the carbon granules in tail gas
Son is sticked on filter screen or tank inner wall because immersion swells, and when the carbon particle on filter screen is accumulated to a certain extent, can be caused
Water level rises to over the height value of setting, now, if being participated in containing more polymictic water after circulation, can be attached to impurity and lead
In hot plate, the heat conductivility of heat-conducting plate can be reduced in the course of time, or even can corrode heat-conducting plate, and the recirculated water containing impurity is by temperature
Degree influence is also easy to produce peculiar smell；It therefore, it can set water level detector in the first water tank, when water level exceedes the height value of setting
When, detector can detect the too high signal of water level, in-car is sent alarm, to remind occupant to clean water tank, so as to carry
Senior staff officer and the cleannes of the water of heating, eliminate peculiar smell, extend the service life of heat-conducting plate.
In-car warm-air feed method provided in an embodiment of the present invention, using the heat-supplying mode of floor heating, makes the temperature in driver's cabin
Degree is able to uniformly spread, it is ensured that the occupant of any position can enjoy consistent heating temperature in driver's cabin, improve and multiply
The comfort level of member；In addition, by using the mode of tail gas heating, can be recycled waste gas resource, while can filter
Fall the impurity in waste gas, reduce exhaust emission, in addition it is also ensured that participating in the cleannes of the recirculated water of heating, eliminate peculiar smell.
Construction, feature and the action effect of the present invention, above institute is described in detail according to the embodiment shown in schema above
Only presently preferred embodiments of the present invention is stated, but the present invention is not to limit practical range shown in drawing, it is every according to structure of the invention
Want made change, or be revised as the equivalent embodiment of equivalent variations, still without departing from specification with illustrating during covered spirit,
All should be within the scope of the present invention.
