Description

The vehicle-mounted water drinker of heating by the exhaust gases

Affiliated technical field

The utility model relates to a kind of device that utilizes the waste gas residual heat heating drinking pure water of I. C. engine.The driver and conductor who is mainly driving vehicle provides drinking water, also can be fixing use I. C. engine the staff drinking water is provided.

Background technology

Current automobile has entered huge numbers of families, and Chinese have the custom of drinking water, and other all being provided with in most car seats placed the device of drinking water tumbler, and automobile-used water drinker does not enter automobile all the time, does not satisfy the custom of compatriots' drinking water.

Disclosed before this automobile water drinker invention technology majority all is to use electro heat.And the effect of storage battery on the automobile and electrical generator is the needs that guarantee automobile normal running, and electric weight more than needed is limited; And hot-water heating system is high-power highly energy-consuming device, uses it and automobile to strive the cruising that electromotive force must influence automobile for a long time.It is to utilize the heat heating potable water of engine cooling circulating water that an invention disclosed technology is arranged, and the normal working temperature of engine cooling circulating water is generally at 70 ℃, and therefrom heat-obtaining certainly will influence the temperature traverse of driving engine, is unfavorable for the normal operation of driving engine; It two is that 70 ℃ circulating water temperature is difficult to potable water is boiled.So above technological invention does not obtain practical application and popularization.

Summary of the invention

The waste gas of automotive engine is outside car is discharged in freeing pipe noise reduction cooling back, and engine exhaust temperature when entering freeing pipe and enter the mouth promptly can not influence the normal operation of driving engine up to 300 ℃ at this place's heat-obtaining, can obtain higher temperature again.The heat efficiency of automotive engine has only about 0.3, and wherein 40% heat energy is taken away by waste gas.The utility model technology is exactly that to utilize a part of heat energy in the engine exhaust be that vehicle-mounted water drinker heating is used.The medium duty engine of one 1.6 liter capacity for example, power wherein had the heat of 30Kw to be taken away by waste gas about 70Kw approximately, as continuous firing 1 hour, therefrom extracting 10% heat can boiled 20 liters of hot water, is enough to drink for 2 families or one 10 people's office.The utility model technology can be applied on all mobile, fixing I. C. engines, and applying of this technology will be played good environmental-protection function for the energy-saving and emission-reduction of society.

Principle of work of the present utility model such as Fig. 1 are shown in Figure 2, the basic structure of heating part is made up of water butt (9), flow regulating valve (11), electromagnetic valve (12), each unit Series of evaporator (13), and electric part is composed in series automatic control circuit by 95 degree normally closed sensors (8), 120 Du Changkai sensors (14), electromagnetic valve (12).Turn on the power switch K1, power light D1 is bright, opens the lid of filling pipe end 1, the normal temperature pure water joins in the water butt 9 by filling pipe end 1, since the electric conductivity of water, high water level sensor 5 conductings when water is added to high water level, D4 is bright for the high water level indicator lamp, and expression water is filled it up with, stops to add water.After engine operation, vehicle exhaust emissions tube inlet 15 place's temperature begin to rise, when temperature rises to 120 ℃, 120 Du Changkai sensors, 14 closures, 95 spend normally closed sensor 8 closures at normal temperatures, electromagnetic valve 12 conductings this moment, valve open, burner on light D3 lights simultaneously.Pure water in the water butt 9 has in the inflow evaporator 13 of control by flow regulating valve 11 electromagnetic valves 12, and pure water runs into scorching hot evaporator 13 and becomes aqueous vapor, and aqueous vapor enters in the water butt 9 by U-shaped pipe 4, and the pure water in the bucket is heated.One end of U-shaped pipe (4) connects evaporator (13), and the other end inserts in the water butt (9).The effect of U-shaped pipe 4 is in the pure water inflow evaporator 13 that prevents in the bucket.When the pure water in the bucket was heated to 95 ℃, the normally closed sensor 8 of 95 degree was opened, electromagnetic valve 12 outages, and valve closing, the pure water of inflow evaporator 13 stops, and evaporator is because anhydrous steam stops heating.When the temperature fall to 85 of water in the bucket ℃, the normally closed sensor 8 of 95 degree is closed once more, and burner on light is lighted once more, and water produces aqueous vapor in the inflow evaporator 13 once more, repeats above heating action.

When burner on light D3 extinguishes, illustrate that the water in the bucket is heated, can drink.Press hot water pump K switch 2, hot water pump 6 is started working, and D2 is bright for the water outlet indicator lamp, and boiling water flows out from hot water tap 2.Unclamp hot water pump K switch 2, hot water pump quits work, and water outlet indicator lamp D2 extinguishes, and hot water stops to flow out.This water dispenser can once have been put the hot water in the water butt 9, and this water dispenser is not afraid of dry combustion method.

The effect of flow regulating valve 11 is sizes of control current, and it is minimum to guarantee to remain in after electromagnetic valve 12 is closed in the evaporator 13 water, stops heating as early as possible.High water level sensor 5 and low water level sensor 7 can be by the height of indicator lamp D4, D5 indication water butt 9 median water level, so that replenish pure water at any time.The heat-insulation layer 10 of water butt 9 outsides can play insulation effect to the water after the heating.The effect of excessive gas port 3 is expanding gas of in time getting rid of in the bucket, when the water mistake can play spillway when filling with.This vehicle-mounted water drinker must use pure water, otherwise the easy fouling of pipeline is stopped up.
