For field technique personnel, the omitting of some known structures and their instructions in the attached drawings are understandable.
Embodiment 1
A kind of drivers' cab warm-air drier, as shown in Figure 1, including cabinet 1, it is electromechanical to be equipped with warm wind as shown in Figure 4 in cabinet 1
Road comprising control loop 2 and fever circuit 3, control loop 2 include contactor coil 21, and fever circuit 3 includes hair in parallel
Hot branch and blower branch, fever branch include probe of contactor 31 and with the concatenated heater element 32 of probe of contactor 31, wind
Machine branch includes that the heat for generating heater element 32 is distributed to the blower 33 outside cabinet 1.
Contactor coil 21 and probe of contactor 31 are a set of whole contactor.The connect supply voltage of control loop 2 is
110V, fever the connect supply voltage in circuit 3 are 220V, and electric wire passes through the switching of the concentration of connector 6 into cabinet 1 in each circuit
Interior, the present embodiment is that the heater element 32 controlled in fever circuit by contactor generates heat, and realizes low voltage control high pressure, guarantees electricity
Stablize on road, it is ensured that heater element keeps working normally.
As depicted in figs. 1 and 2, the space around heater element 32 forms air duct 4, and blower 33 is set to 32 top of heater element
Or lower section (referring to the physics upper and lower position after cabinet installs above or below mentioned here), as shown in figure 3, cabinet 1 exists
Heater element 32, blower 33 setting position at cabinet wall be in grid aeration structure 11, grid corresponding with heater element 32
Aeration structure 11, which can effectively ensure that in warm-air drier, has enough air to flow, and grid aeration structure 11 corresponding with blower 33 can make
The air being heated sheds in due course provides a home from home outside to cabinet for drivers' cab.
The components that not set correlation takes up space around the heater element of the present embodiment, 4 resistance of air duct is small, is conducive to blower 33
Heat is distributed to outside cabinet 1 in time.
To realize being rapidly heated for drivers' cab, fever branch road is equipped with multiple heater elements 3 (the present embodiment three in parallel
It is a), multiple heater elements generate heat simultaneously, can significantly improve heating efficiency.
Heater element 3 specifically uses finned electrothermal tube, and heating area is big, and heat loss reduces, and under equal-wattage,
It has many advantages, such as that quick heating, fever is uniform, electric conversion efficiency is high for common electrothermal tube.
The blower 33 of the present embodiment uses cross flow fan, and axial length is unrestricted, can select according to actual needs suitable
The draught fan impeller of suitable length, and by the effect of blade power twice when air-flow is flowed through draught fan impeller, air-flow can reach far
Distance, furthermore it also has outlet air uniform, the feature of no turbulent flow.
To avoid drivers' cab warm-air drier over-heat inside from generating damage, can connect fusible link 5 in control loop 2, fusible link
For temperature fusible link, fusing-off temperature is 121 DEG C, so that it is stopped working in the case where can effectively ensure that warm-air drier over-heat inside.
Fever circuit 3 in can also accordingly connect fusible link 5(the present embodiment fever circuit in it is not set), warm-air drier it is whole
Body running process, which provides, further to be ensured.
It is adjustable for the temperature that further realizes drivers' cab, so that drivers' cab is reached one compared with stationary temperature environment, controls back
Also be in series in road 2 at least one temperature detect switch (TDS) 23(the present embodiment there are two settings), temperature detect switch (TDS) controlled at 80
℃。
Two temperature detect switch (TDS) setting positions relatively disperse, and can be separately positioned on the position that heater element length direction leans on close end
Set, one in left end, one in right end, so temperature detect switch (TDS) 23 can at-once monitor go out the temperature feelings of different corners in cabinet
Condition, when there is overheat condition, corresponding temperature detect switch (TDS) be will be switched off, and disconnect control loop, so that heater element be made to stop
Fever so adjusts the indoor integrated environment temperature of driver in due course, provides reference for the uniform situation of bulk temperature in air duct.
Certainly, when temperature in chassis value is reduced to temperature detect switch (TDS) recovery value, (such as recovery value is 65 DEG C or 70 DEG C), temperature detect switch (TDS) can be again
Secondary automatic closure recloses fever come the circuit that makes to generate heat, to readjust the indoor environment temperature of driver rapidly.
It is additionally provided with the time-delay relay coil 22 in parallel with contactor coil in control loop 2, is in series in blower branch
Time-delay relay contact 34, time-delay relay coil 22 and time-delay relay contact 34 are a set of whole time-delay relay.
Time-delay relay can ensure that time-delay relay contact 34 is still in attracting state, at this when control loop 2 disconnects
Under state, blower 33 remains to work normally, and the waste heat of heater element 32 is dispelled to drivers' cab as much as possible, to guarantee entire
The service life of drivers' cab warm-air drier.
The delay time of time-delay relay is 30 seconds in the present embodiment, and the suction of cross flow fan is big, and radiating efficiency is high, 30
The waste heat in heater element and cabinet can be made all to distribute to outside cabinet completely in second.
The circuit control of the drivers' cab warm-air drier of the present embodiment are as follows: manual ON control loop 2, temperature detect switch (TDS) are normally closed shape
State, contactor coil 21 is started to work and control contactor contact 31 is attracted, and makes each heater element 32 start to generate heat, same to time delay
When relay coil 22 also start to work and control time-delay relay contact 34 actuation, so that blower 33 is devoted oneself to work will be in air duct 4
Hot-air absorb and dispel to the drivers' cab outside cabinet 1, two equal real-time monitorings of temperature detect switch (TDS) 23 in this process
The temperature of corresponding position, once the temperature that any one temperature detect switch (TDS) is monitored has reached the temperature controlling value of the temperature detect switch (TDS)
When, which disconnects, and disconnects control loop, and the circuit that generates heat therewith disconnects, and heater element 32 stops fever, makes
Temperature in cabinet enters slow cooling process, adjusts the whole heating temperature in cabinet 1 with this.
With the reduction of temperature in chassis, when temperature detect switch (TDS) 23 monitors that corresponding temperature reaches the temperature control of lower temperature
When value processed, then automatic closure generates heat circuit then and turn on automatically, hair when two temperature detect switch (TDS)s 23 are in closed state again
Thermal element 32 connects fever, starts temperature in chassis again in rising trend.
When the drivers' cab warm-air drier need to be closed, control loop 2 is disconnected manually, and probe of contactor 31 disconnects at this time, owns
Heater element 32 stops working, and time-delay relay contact 34 will be delayed 30 seconds just disconnection, in this 30 seconds, blower 33 still in
Air draught and outlet air working condition can rapidly distribute waste heat in cabinet 1 to the cabinet external world.
Fusible link 5 then provides circuit safety guarantee for control loop 2.
This drivers' cab warm-air drier has electric conversion efficiency height, quick heating, thermal sensation strong, the flames of anger, unglazed consumption, securely and reliably
The features such as, it is mountable in a plurality of vehicles, particularly suitable for being mounted on power concentration formula train, it is installed in wall after drivers' cab
In the cabinet of side, drivers' cab space will not be largely occupied, and simple and beautiful, while suitable heating environment can be provided for drivers' cab.
Obviously, above-described embodiment is only intended to clearly illustrate the technical solution of the utility model example, and simultaneously
Non- is limitations of the embodiments of the present invention.For those of ordinary skill in the art, above explained
On the basis of can also make other variations or changes in different ways.There is no need and unable to give thoroughly all embodiments
