Should be noted that: can on second pipeline parts 212, the heater element (not shown) can be set.
Referring to Fig. 9 A, 9B and Figure 10, Fig. 9 is the reduced graph of Fig. 2 A-212 1 kinds of alternate embodiment of second pipeline parts shown in Figure 5, Fig. 9 B is the cutaway view of being done along the IXB-IXB line among Fig. 9 A, cutaway view among Figure 10 has been represented another embodiment of subassembly shown in Figure 4, and this cutaway view has comprised Fig. 9 A, the situation of 9B illustrated embodiment when being in two kinds of work trends.Fig. 9 A and Fig. 9 B have expressed more flexible and second pipeline parts 282 flexibility, and it preferably is made as one with the barrier film 284 with elasticity and flexibility.Enter into the path flows of the liquid of second pipeline parts 282 along a labyrinth shape at liquid inlet handhole 286 places, this route is to be formed by the bigger flow-stopping plate 288 of rigidity, between big and rubber-like bottom 290 and the barrier film 284, bottom 290 wherein preferably is combined as a whole with flow-stopping plate 288 these flow-stopping plates 288 in flexibility.One or more holes 292 that liquid is made on barrier film 284 flow out from second pipeline parts 282.
As the special expression of Figure 10; second pipeline parts 282 is set provides freeze protection for liquid heating subassembly 208; reason is: when the liquid in first pipeline parts 210 freezes; the expansion of liquid makes barrier film 284 outwards bloat from first pipeline parts 210, and expand in the volume of second pipeline parts 282.Thereby the expansion of liquid has been received in first pipeline parts 210, can not make first pipeline parts 210 cracking or cause other damage.In second pipeline parts 282 liquid freeze and the displacement of barrier film 284 in second pipeline parts, 282 volumes dashed forward by the outward bulge of elastic bottom 290 and received.
The structure of aforesaid liquid heating subassembly 208 comprises one first pipeline parts 210 and one second pipeline parts 282, first pipeline parts 210 directly links with heater element, second heater element does not directly link with heater element, but keeping heat exchange relationship comparatively slowly with first pipeline parts 210, this structure of liquid heating subassembly also has advantage: provide the limited function that preheats for the liquid that transports, at first enters into second pipeline parts 282 from container 112 (see figure 1)s and then flow to first pipeline parts 210.
Referring to Figure 11, this view is a sequential chart of simplifying, and it has represented the working process of Fig. 1 to system shown in Figure 10.As can be seen from Figure 11, optimum system choosing ground is to be triggered by a user, and this user for example is the chaufeur of self-propelled vehicle 100 (see figure 1)s, and it realizes triggering by pushing operator's starting switch 130, as shown in Figure 1, this switch generally is positioned on the instrument carrier panel of vehicle.But should be noted that: preferably, in the institute that vehicle ' free on-even before trigger action person starting switch 130, FET232 (seeing Fig. 2 B and Fig. 3) just makes heater element 222 work according to continuous mode, thereby the liquid that liquid can be heated in the subassembly 208 remains at least 65 degrees centigrade (only for example on) the temperature.If the ambient temperature of liquid heating subassembly 208 exceeds this liquid and keeps temperature, then preferably, FET232 ends or the work of reduction liquid heating element 222, thus can prevent overheated.
Preferably, after user's starting switch 130, relay 228 and 230 moves and makes cooresponding heater element 218 and 220 work, and this will provide fast speed anxious heat effect to the liquid in first pipeline parts 210.The temperature that detects liquid in first pipeline parts 210 when sensor 226 has reached one first predetermined rising temperature-when being generally 85 degrees centigrade, one of in two pumps 114,142 or all start working, go out from 210 pumpings of first pipeline parts and will heat back liquid, and make the injected device 124 of heating back liquid eject.Two pumps 114,142 or the work of one of them make to come from the not heating liquid of container 112 or be subjected to very little heated liquid and at first are transported in second pipeline parts 212, then is transported in first pipeline parts 210, to heat again.
In brief, the work in above-mentioned two pumps 114 and 142 one or both of makes and is descended by sensor 226 detected fluid temperature.When being dropped under the predetermined threshold (being generally 55 degrees centigrade) by sensor 226 detected fluid temperature, the work of pump 114,142 stops.When further heat effect makes when rising to one second predetermined rising temperature once more by sensor 226 detected fluid temperature, restart the work of pump, wherein, the second predetermined rising temperature preferably less than the first predetermined rising temperature, is generally 65 degrees centigrade.After user's trigger switch 130, this intermittent duty of two pumps or a pump 114,142 is scheduled to a circulation continuously or is continued predetermined duration, carries out four circulations usually.
Should be noted that: after switch 130 was touched by the user, the power requirement of system had significant increase, and keeps constant basically, when last working cycle after this shake-ups is operated is finished till.
In addition, it is to be noted: for each startup of switch 130, that working cycle (being referred to by label 300) will be longer than other spraying cycle (being referred to by label 302) subsequently usually at first.It should be appreciated that: if the user to the triggering of switch 130 in FET232 and heater element 222 are started working the back short time, take place-for example in 1 to 2 minute after self-propelled vehicle 100 is started working, spraying cycle 300 when then initial will be shorter than the initial cycle 304 under another situation, in another situation, late a lot of when starting working than self-propelled vehicle 100 when the user triggers switch 130.
In addition, time delay between when it is pointed out that operator's starting switch 130 and spraying cycle 300 beginning first is much larger than operator's starting switch 130 and the time delay between the spraying cycle 304 first, wherein, under one situation of back, two operations almost are simultaneous.These characteristics are because the special construction of aforesaid liquid heating subassembly 208 on part, be that subassembly comprises one first pipeline parts 210, it directly links to each other with heater element, subassembly also comprises one second pipeline parts, and (it is referred to by label 212 in Fig. 2 A-Fig. 8, in Fig. 9 A-Figure 10, refer to) with label 282, it does not directly link to each other with heater element, but is keeping heat exchange relationship slowly with first pipeline parts 210.Liquid heating subassembly 208 also has advantage: to transporting, at first enter in second pipeline parts (referred to by label 212 at Fig. 2 A-Fig. 8, referred to by label 282 in Fig. 9 A-Figure 10) from container 112 and then the liquid that flows in first pipeline parts 210 provides the limited function that preheats.Second pipeline parts is set (to be referred to by label 212 in figure Fig. 2 A-Fig. 8, in Fig. 9 A-Figure 10, refer to by label 282) carry out first the speed of spraying cycle after can't starting working to vehicle immediately and bring significant adverse effect, but following speed there is tangible advantageous effects: after the long period that vehicle is started working, carry out the speed of spraying cycle 304 first with heating back liquid.
Barrier film can be used as the fact of good insulator in a short time can bring above-mentioned favourable function, and can prevent that a large amount of heats exhales in the process of the liquid in first pipeline parts 210 being carried out Fast Heating from first pipeline parts, but in long-term, barrier film allows heat to see through, so that the liquid in first, second pipeline parts is heated to second predetermined temperature-even before switch 130 persons of being operated trigger.
Thereby, after in case vehicle has travelled for a long time, behind operator's starting switch 130, the spraying cycle first 304 of heating back liquid almost just can appear using immediately, in addition, the spray volume of heating back liquid also is very big, carry out liquid spray volume after the heating of spraying after normally vehicle is started working immediately 3 times.

Referring to Figure 15, this accompanying drawing is a sequential chart of simplifying, and it has represented the working process of Figure 12 to system shown in Figure 14.As can be seen from Figure 15, the liquid operation automatically controlled preferably that is ejected into trailer-mounted radar antenna 1126 from trailer-mounted radar antenna eductor 1124.When vehicle in motion, if trailer-mounted radar starting switch 1130 in running order (seeing Figure 12), the accumulations of deposit on trailer-mounted radar antenna 1126 such as mud, mud, rainwater and snow will make AGC start heating back liquid and discharge system's (seeing Figure 12-14), and will be described below.
Preferably, in the institute that vehicle ' free on-even when trailer-mounted radar is not activated, FET 1232 (seeing Figure 13 B and Figure 14) just makes heater element 1222 work according to continuous mode, thereby the liquid that liquid can be heated in the subassembly 1208 remains on the preferred temperature of 65 degrees centigrade (for example) at least.If the ambient temperature of liquid heating subassembly 1208 exceeds this liquid and keeps temperature, then preferably, FET 1232 ends or reduce the work of liquid heating element 1222, and is overheated to prevent.
When AGC exists on owing to trailer-mounted radar antenna 1126 deposit to produce a signal that is at least predetermined threshold (referring to by label 1300) herein, one of in two pumps 1114,1142 or all start working, go out from 1210 pumpings of first pipeline parts will heat back liquid, and make heating back liquid be ejected by trailer-mounted radar antenna eductor 1124.Two pumps 1114,1142 or the work of one of them make to come from the not heating liquid of container 1112 or be subjected to very little heated liquid and at first are transported in second pipeline parts 1212, then is transported in first pipeline parts 1210, to heat again.
In a short time, the work in above-mentioned two pumps 1114 and 1142 one or both of makes and is descended by sensor 1226 detected fluid temperature.When being dropped under the predetermined threshold (being generally 55 degrees centigrade) by sensor 1226 detected fluid temperature, the work of pump 1114,1142 stops.When further heat effect makes when rising to a predetermined rising temperature once more by sensor 1226 detected fluid temperature, the work of restarting pump, wherein, predetermined rising temperature is generally 65 degrees centigrade.This intermittent duty of two pumps or a pump 1114,1142 carries out continuously, drops to predetermined threshold value below 1302 up to the signal of AGC.
