Abstract
The utility model relates to an automatic controlling ventilation device of an air conditioning car. The front section of a total air inlet port 4 of an engine 5 is connected with an air filter 3, and a branch air inlet pipe 6 is communicated with and arranged on a main air inlet pipe which is arranged on the front section of the air filter 3. An air inlet port of the branch air inlet pipe 6 is arranged in a car body and is at a venturi pipe 2 of the main air inlet pipe. A rubber pipe 7 is communicated with a vacuum valve 8 which drives an adjusting pull rod 9 which drives a throttle valve 10 which is arranged in the main air inlet pipe 1 to control the air inflow of the main air inlet pipe 1. Suction openings of two air inlet pipes of an empty filter of an engine are respectively positioned in the car body and out of the car body. On one hand, air B is directly sucked and on the other hand air A is sucked from the outside of the car body. Negative pressure which is generated by the venturi pipe causes the action of the vacuum valve, and the adjusting pull rod is pulled to control the throttle valve. Then, air suction quantity from the outside of the car body is adjusted and the rotation speed of the engine changes. Airflow pressure in the venturi pipe can be changed to change the degree of opening and closing the throttle valve. Then, the adjustment of the air inlet proportion from the inside and the outside of the car body is realized, air circulation in the car body is promoted and the ventilation effect is achieved.
Description
Technical field
The utility model relates to the Air conditioner air exchange mode of air-conditioned coach, is by changing traditional engine charge mode, making driving engine participate in the air in a car compartment circulation, by the rotating speed control ventilation volume of control driving engine.
Background technology
At present, the air inlet of driving engine all is to derive from outside the compartment, and the ventilation system of air-conditioned coach all adopts the electronics air-exhaust fan to realize.Because the vehicle rotation speed change of driving engine in the process of moving is bigger, cause voltage fluctuation to occur, the life-span of electronics air-exhaust fan is affected, and fault rate can be in any more all the time, and stability is difficult to guarantee, produces noise and power consumption simultaneously.Air circulation in the air-conditioned coach is affected, and easily produces peculiar smell in the compartment.
Summary of the invention
Shortcomings such as existing car ventilation system stability is poor in order to overcome, power consumption, noise are big, the utility model provides the automatic guidance air interchanger of a kind of dependable performance, energy-saving and environmental protection.
The technical solution of the utility model is: change conventional engines by car external admission mode, in the compartment, set up the inlet scoop, its structure composition includes: main air inlet pipe, an air inlet pipe, vacuum valve, adjusting yoke, throttle gate, on the leading portion master air inlet pipe of airfilter, connect an air inlet pipe is set, the admission port that props up air inlet pipe is located in the compartment, Venturi tube place at main air inlet pipe, there is a sebific duct to be connected with vacuum valve, vacuum valve affects adjusting yoke, adjusting yoke drives the throttle gate in the main air inlet pipe, controls the suction quantity of main air inlet pipe.
That throttle gate also can adopt is automatically controlled, temperature control, difference of pressure automatic control or artificial (driver) control etc.
Driving engine absorbs the air that purifies through airfilter and burns, air-cleaner snorkel is a three-way pipe, its two inlet scoops lay respectively in the compartment and the compartment outside atmosphere, when driving engine moves, directly air-breathing by driving engine on the one hand from the compartment, the negative pressure that produces by Venturi tube causes the vacuum valve action on the other hand, then spur adjusting yoke control throttle gate, thereby realize the function of air draught outside the compartment, the rotation speed change of driving engine can change stream pressure in the Venturi tube, thereby change throttle gate folding degree, realize adjusting in the compartment, the ratio of external air inlet promotes the compartment airiness, reaches ventilation effect.
The present invention changes conventional engines by car external admission mode, in the compartment, set up the inlet scoop, by Venturi tube, vacuum valve control throttle gate size, the same compartment of engine air filter admission port, the outer atmosphere of car are linked to each other, therefore air inlet source air environment from simple compartment outside of driving engine is transformed into the outer atmosphere of air conditioner surroundings and compartment in the compartment, and passes through the air inlet ratio inside and outside the motor speed control compartment.Realize automatic guidance ventilation in the compartment.
Effect of the present utility model is: fresh air outside the compartment and the vitiated air in the compartment can be automatically changed in ratio of setting and speed, by driving engine rotating speed control; Dirty or the air that carries disease germs that is replaced in the compartment is just discharged after the high pressure-temperature sterilization, pollutant atmosphere not, and whole air inerchange process is consumes energy and generation noise in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, leading portion at total admission port 4 of driving engine 5 is connected with airfilter 3, on the leading portion master air inlet pipe 1 of airfilter 3, connect an air inlet pipe 6 is set, the admission port that props up air inlet pipe 6 is located in the compartment, at Venturi tube 2 places of main air inlet pipe, there is a sebific duct 7 to be connected with vacuum valve 8, vacuum valve 8 affects adjusting yoke 9, adjusting yoke 9 drives the throttle gate 10 in the main air inlet pipe 1, controls the suction quantity of main air inlet pipe 1.In the accompanying drawing inlet scoop of two air inlet pipes of the empty filter 3 of driving engine 5 lay respectively in the compartment and the compartment outside, one side is the air-breathing B from the compartment directly, air-breathing A outside the compartment on the other hand, the negative pressure that produces by Venturi tube 2 causes vacuum valve 8 actions, then spur adjusting yoke 9 control throttle gates 10, thereby realize the function of air draught outside the compartment, the rotation speed change of driving engine, can change stream pressure in the Venturi tube 2, thereby change throttle gate folding degree, realize adjusting the ratio of the inside and outside air intake in compartment, promote the compartment airiness, reach ventilation effect.
Claims (2)
1, a kind of air-conditioned coach automatic guidance air interchanger, include: main air inlet pipe (1), an air inlet pipe (6), vacuum valve (8), adjusting yoke (9), throttle gate (10), it is characterized in that going up perforation at the main air inlet pipe (1) of airfilter (3) leading portion is provided with an air inlet pipe (6), the admission port that props up air inlet pipe (6) is located in the compartment, Venturi tube (2) in main air inlet pipe (1) is located, there is a sebific duct (7) to be connected with vacuum valve (8), vacuum valve (8) affects adjusting yoke (9), and adjusting yoke (9) drives in the main air inlet pipe and controls the throttle gate (10) of its suction quantity.
