Description

Parking heater

Technical Field

The utility model relates to the technical field of auto-parts, concretely relates to parking heater's institutional advancement.

Background

The parking heater is a vehicle-mounted heating device independent of an automobile engine, supplies heat to the automobile through self combustion, and can independently preheat and heat a parked automobile engine and a cab in a low-temperature cold environment in winter. When the air conditioner works, the main motor of the heater drives the air inducing wheel and the combustion-supporting fan to rotate. The fuel feed pump sends inhaled fuel to the atomizer through defeated oil pipe way, and the atomizer volatilizes through self heat and mixes fuel atomization back and the inspiratory air of combustion-supporting fan in main combustion chamber, is lighted by incandescent glow plug, turns back after abundant burning in the combustion chamber, through inner wall and above fin, comes out the heat transfer. The waste gas burned by the heater is discharged by a smoke discharge pipe. The working principle of the vehicle is that the storage battery and the independent oil tank of the vehicle are utilized to supply power and a small amount of oil instantly, and the vehicle is warmed by heat generated by burning diesel oil. The existing parking heater is only provided with one set of oil supply and ignition device, and when the parking heater is used, although faults can be found in time through the ECU alarm of the control device, the parking heater cannot be recovered to be used without professional maintenance. Once the oil supply device and the ignition device are in failure, the parking heating function is lost, so that the use feeling is influenced, and the maintenance cost is not low.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: in view of the above problems, a parking heater having a backup ignition device is provided.

The technical solution of the utility model is that: the utility model provides a parking heater, includes oil supply unit, ignition, combustion chamber and controlling means, and oil supply unit's fuel feed pump passes through the pipeline and supplies the oil to the combustion chamber, and ignition's ignition plug sets up in the atomizer at combustion chamber rear portion and supplies the connector of oil pipe way, and the fuel atomizes through the atomizer and ignites by the ignition plug, the ignition plug has two, and the oil pipe way of being connected with the atomizer is two, connects on the atomizer through two connectors respectively, and the ignition plug is established respectively in two connectors, can switch to another ignition plug work when an ignition plug trouble.

The technical effects of the utility model are that: the novel oil-gas separator has the advantages of reasonable structural design, low emission, low oil consumption, economy, durability and reliable operation, can greatly improve the working reliability of equipment, and reduces the maintenance cost. The atomization felt net adopts iron-chromium-aluminum felt, and has the characteristics of long service life, environmental protection, energy conservation, high temperature resistance, deformation resistance, no carbon deposition and good toughness.

Detailed Description

As shown in fig. 1, 2 and 3, a parking heater comprises an oil supply device, an ignition device, a combustion chamber 1 and a control device, wherein an oil supply pump of the oil supply device supplies oil to the combustion chamber 1 through a pipeline 2, an ignition plug 3 of the ignition device is arranged in an atomizer 4 at the rear part of the combustion chamber 1 and a connector 5 of the oil supply pipeline 2, the fuel is atomized by the atomizer 4 and ignited by the ignition plug 3, the control device controls the execution component to work and detects the working state of the execution component, a fault diagnosis is made by a feedback signal and a fault signal is sent out, the number of the ignition plugs 3 is two, the oil supply pipeline 2 connected with the atomizer 4 is two, the two ignition plugs are respectively connected to the atomizer 4 through two connectors 5, the ignition plugs 3 are respectively arranged in the two connectors 5, and when one ignition plug 3 fails, the other ignition plug 3 can be switched to work. The ECU of the control device sends a fault signal, a fault indicator lamp is turned on to indicate that the first ignition system is in fault, and the second set of spare ignition system can be started to work manually or automatically by the ECU.

The number of the oil supply pumps is two, and the two oil supply pumps are respectively connected with the atomizer 4 through an oil supply pipeline 2.

And the number of the ECU of the control device is two, and the ECU controls one set of the oil supply device and the ignition device respectively.

The number of the oil supply pump can be one, and the oil supply pump is respectively connected with the atomizer 4 through two electromagnetic valves and two oil supply pipelines 2. The control device can only adopt one ECU to complete the control of the two oil supply pipelines through a preset program.

And the atomization felt net 6 of the atomizer 4 is an iron-chromium-aluminum felt net.
