Abstract
The utility model discloses an electrically-driven heating ventilation air conditioner control device for vehicles, relating to the technical field of manufacturing of automobile associated equipment. The control device comprises a controller, an air blower speed regulating device and a PTC (Positive Temperature Coefficient) heater control device, the PTC heater control device consists of a plurality of small-power PTC heating units, each small-power PTC heating unit is connected with a power supply through the normally-open contact of respective relay, the controller is used for controlling the small-power PTC heating unit to switch on/off in sequence through the relays. By adopting the electrically-driven heating ventilation air conditioner control device, the problem that the contact capacity cannot bear the initial great starting current of the PCT heater when an ordinary relay is used for controlling the on/off of the PTC heater of an air condition for vehicles can be solved.
Description
Technical field
The utility model relates to automobile accessories equipment manufacturing technology field, and particularly a kind of vehicle electric drives warm air air-conditioning control setup.
Background technology
When heating, car air-conditioner in the market mostly provides thermal source by PTC heater, very large semi-conducting material or the components and parts of PTC general reference positive temperature coefficient.The PTC heater that this semi-conducting material is made, when normal temperature, its resistance value is lower, along with its resistance value of rising of temperature is increasing of step evolution.Therefore, this PTC heater has the features such as volume is little, heating is fast, heat efficiency is high, temperature automatic constant, but cause the starting current of the heater that ptc material makes very large just because of the reason of this positive temperature coefficient, particularly the initial start electric current of high-performance car air-conditioner PTC heater is very large, and general relay contact is difficult to bear.
Utility model content
The utility model provides a kind of vehicle electric to drive warm air air-conditioning control setup, and it can solve while using common relay control car air-conditioner PTC heater break-make, and contact capacity is difficult to bear the large problem of PTC heater initial start electric current.
In order to address the above problem, the technical scheme that the utility model adopts is: this vehicle electric drives warm air air-conditioning control setup, include controller, one end of blowing engine speed regulation device is connected with the 1st port of described controller, one end is connected with the 2nd port of described controller, and its other end is connected with the 3rd port of described controller; The 10th port that blowing pattern actr one end is connected with described controller connects, and one end is connected with positive source, and its other end is connected with power cathode; Return air temperature sensor one end is connected with described controller the 9th port, and its other end is connected with power cathode; Also comprise PTC heater control setup, described PTC heater control setup one end is connected with the 6th port of described controller, and described PTC heater control setup one end is connected with the 7th port of described controller.
In technique scheme, can also be more specifically: described PTC heater control setup is by multiple miniwatt PTC heating monomer compositions, each described miniwatt PTC heating monomer is all connected with power supply by the normally open contact of relay separately, and described controller turns on and off by miniwatt PTC heating monomer described in described Control successively one by one.
Further: described controller is micro controller system.
Owing to adopting technique scheme, the utility model compared with prior art has following beneficial effect:
1, the utility model, by connecting one by one successively miniwatt PTC heating monomer, can effectively reduce each relay load, can meet the requirement of break-make PTC heater completely.
2, the utility model is connected miniwatt PTC heating monomer successively by time delay, and can effectively reduce PTC heater and start the impact of large electric current on power supply, thus the service life of prolongation PTC heater and power supply.
Accompanying drawing explanation
Fig. 1 is electrical principle schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Vehicle electric shown in Fig. 1 drives warm air air-conditioning control setup, and one end of blowing engine speed regulation device 3 is connected with the 1st port of controller 1, and one end is connected with the 2nd port of controller 1, and its other end is connected with the 3rd port of controller 1; In the present embodiment, controller 1 is micro controller system, and by blowing engine speed regulation device 3, controller 1 can be controlled the rotating speed of blowing engine 4 in high, medium and low three gear conversions; Blowing pattern actr 5 one end are connected with the 10th port of controller 1, and one end is connected with positive source, and its other end is connected with power cathode; Controller 1 can be controlled blowing pattern actr 5 for defrosting mode or blow face pattern; Return air temperature sensor 6 one end are connected with controller 1 the 9th port, and its other end is connected with power cathode; Return air temperature sensor 6 can be by the temperature feedback in operator's compartment to controller 1; PTC heater control setup 2 one end are connected with the 6th port of controller 1, and PTC heater control setup 2 one end are connected with the 7th port of controller 1.Because the power consumption of PTC heater is large, to switch on and off immediate current very large, make the contact of relay be easy to produce arcing phenomenon, therefore adopt time-sharing control system, PTC heater is divided into PTC1 and PTC2, two groups of controls of PTC3 and PTC4, in the time opening heating mode, one group of PTC1 heater work at once, two groups of PTC2 heaters time delay work in 5 seconds is also that successively time delay is closed for 5 seconds equally in the time closing.
By such grouping, make the power reduction of PTC heater, the starting current in the time starting has also diminished, and this starting current is also in the tolerance range of general relay.
