Abstract
The utility model relates to a defroster for windscreens of a driver's cab of vehicles, belonging to an accessory for an automobile. An insulative skeleton which wound with an electrothermal element, a miniature direct current motor, and a fan-blade which is arranged at the shaft end of the motor are arranged in a casing in order. A wind fence and a hot wind nozzle are arranged on the other end of the casing. The utility model is characterized in that the defroster is rapid in defrosting due to the dynamical defrosting by hot wind. The utility model has the advantages of good effect, heating action, simple manufacture technology and low cost. The utility model can ensure that a driver can have favorable sight and can travel safely, being particularly suitable for defrosting for various passenger and freight vehicles.
Description
The utility model relates to a kind of vehicle cab windshield defogger, belongs to car accessories, is particularly suitable for all kinds of passenger-cargo Defroster device for vehicle dresses and uses.
The northern China winter severe cold, the water freezes as it drips, day and night temperature is very big, ice and snow on road surfaces has concurrently, this original automobilist's safety of just giving drives to bring certain difficulty, yet the windshield of operator's compartment is because the factors such as steam in internal-external temperature difference and the expiration are formed one deck frost soon, influence driver's sight line, this has just more increased safety hazard, make heavier on tenterhooks the driving of driver's mental burden, for avoiding traffic accident, while have to drive go to wipe frost on the windshield with hand, so both disperseed driver's energy, dangerous again; The also useful in the past electric heating that is distributed in the multiple film of thread resistance to heat on the glass surface separates white method defrosting but multiple film influences driver's sight line, can not be used for the front windshield glass defrosting.
Notification number provides the snoot that is rolled into similar first cylindricality with sheet metal in 88216834, scribble the far ultrared paint layer in it, purpose made resistance fiber tube is installed in the snoot, the resistance fiber tube is the glass tube made from high-strength high temperature-resistant glass, the resistor wire that turns to tungsten filament is housed in it, the defogger that assembles after vacuumizing, this defogger is big because of its technology difficulty, the cost height, defrosting effect is undesirable and influence it and apply.
The purpose of this utility model is to provide a kind of dump energy of former car that utilizes to be propulsion source, and its defrosting speed is fast, effective heating effect, the vehicle cab windshield defogger that manufacturing process is simple, cost is low, all kinds of passenger-cargo automobile all is suitable for of having concurrently.
Invention thought of the present utility model is almost all to adopt DC shunt generator according to the electrical generator on the automobile, this electrical generator change of voltage when rotation speed change is less, simple structure, voltage-regulation is easy, unlikely burning during short circuit, so can meet the requirement of automobile electrical equipment and battery charge, therefore electrical generator is that the main power supply storage battery that comprises the automotive electrical system of battery ignition in tying up to then only plays auxiliary and adjustment effect, moreover about this car of power 350W power consumption 130W of 12V automobile current generator; The power 500W of 24V diesel-powered vehicle electrical generator, about this car power consumption 160W, it is a waste that unfortunate this unnecessary electric energy is not fully used, based on this thought, designing a kind ofly neither influences defogger that the normal use of former car can fully utilize dump energy again it is realized by the following technical solutions, be by shell, the insulation framework of electric heating element is housed, DC micromotor and the fan rotor that is loaded on its axle head are loaded in the shell in turn, air grid and hot air spout are loaded on the other end of shell, and travel(l)ing rest is loaded on front windshield bottom by bolt of rear end plate corresponding site DC micromotor links to each other with the power supply of former automobile-used electric equipment respectively with electric heating element.
Described electric heating element is that its rated voltage of resistor wire is that 12V or 24V power are 200W or 300W.
The utility model compared with prior art because hot air dynamic defrosting is so defrosting speed is fast, effectively has the heating effect concurrently, and manufacturing process is simple, and cost is low, guarantees that the driver has good sight line, guarantees safe in operation.
Fig. 1 is a main TV structure scheme drawing of the present utility model.
Fig. 2 is that A is to structural representation.
Fig. 3 is the embodiment of electric heating element.
Fig. 4, the 5th is enclosed in interior embodiment with electric heating element.
Enforcement of the present utility model is described in conjunction with the accompanying drawings: shell 5, hot air spout 1, air grid 2 usefulness injection mouldings or sheet stamping moulding, be wound with the insulation framework 3 of electric heating element 4, DC micromotor 6 is loaded in the shell 5 in turn, fan rotor 7 is contained on the motor shaft, air grid 2 and hot air spout 1 are contained in the other end of shell 5, travel(l)ing rest is contained in the corresponding site of windscreen bottom by bolt of rear end plate 10, the power lead 8 of DC micromotor 6 and electric heating element 4 links to each other with the power lead of former automobile-used electric equipment respectively with 9, shown in Figure 3 11, shown in Figure 4 12 and shown in Figure 5 13 is embodiment of electric heating element, its electric heating element 4 is resistor wires, its rated voltage is 12V or 24V, power is 200W or 300W, is suitable for gasoline car and diesel-powered vehicle respectively.
Claims (2)
1, a kind of vehicle cab windshield defogger is made up of shell 5 and electric heating element 4, it is characterized in that being wound with the insulation framework 3 of electric heating element 4, and DC micromotor 6 and the fan rotor 7 that is loaded on axle head thereof are loaded in the shell 5 in turn; Air grid 2 and hot air spout 1 are loaded on the other end of shell 5, and travel(l)ing rest is contained in the corresponding site of windscreen bottom by bolt of rear end plate 10, and the power lead 8 of DC micromotor 6 and electric heating element 4 links to each other with the power lead of former automobile-used electric equipment respectively with 9.
2, defogger according to claim 1 is characterized in that described electric heating element 4 is resistor wires, and its rated voltage is 12V or 24V, and power is 200W and 300W.
