Abstract
The utility model discloses an overhead defrosting unit heater for tractor cabs, comprising a motor assembly, a unit heater core, an upper shell, a lower shell, an air door and an air door controller, wherein the motor assembly is arranged in a semicircular volute of the lower shell; the unit heater core is arranged in a slot in the middle of the lower shell; the air door is arranged inside an air outlet; the air door controller is arranged outside the air outlet and butted with a main shaft of the air door; an upper shell contact surface is tightly buckled on a lower shell contact surface and surrounding connection holes are tightly sealed by bolts. Meshed concave and convex shallow slots are arranged on the upper shell contact surface and the lower shell contact surface. The overhead defrosting unit heater for tractor cabs is reasonable in structure and has the advantage of effectively solving the frosting problem of front glass of tractor cabs without influencing the heating; and as the vision of the drives is not influenced, the operation is flexible and convenient.
Description
Technical field
The utility model belongs to tractor spare field, relates to a kind of tractor cab overhead type defrosting heater unit that defrosts, can warm oneself.
Background technology
At present, the trac. industry of China just develops towards maximization, functional diversities direction, and is more and more to the indoor environmental amenity property requirement of tractor driving.Heater unit is as the main auxiliary equipment on the tractor cab, and its structure and quality are manufacturing firm and user's questions of common interest.Tractor cab heater unit performance of the prior art is single, is heating can not defrost mostly; Trac. is under service conditions, in case front glass frosting in the operator's compartment, the driver can only go to wipe with hand, brings very big inconvenience for driver's sight line and operation; Though what have can defrost, its structure is comparatively complicated, and defrosting effect is also undesirable.Therefore, all good tractor cab heater units of a kind of defrosting of development and heating effect will receive user's favor.
The utility model content
The purpose of the utility model is to provide a kind of tractor cab overhead type defrosting heater unit that can heating can defrost again, to satisfy users' demand.
The utility model can achieve the above object through following technical scheme: tractor cab overhead type defrosting heater unit comprises: motor assembly, warm braw core body, upper shell, lower house, air door, air damper controller; Motor assembly is contained in the semicircle spiral case of lower house; The warm braw core body is contained in the groove of lower house middle part; Air door is contained in the air outlet inboard, and air damper controller is contained in the air outlet outside, docks with the main shaft of air door; The upper shell contact surface closely is buckled on the lower house contact surface, and connecting bore is used the screw fit sealing all around.
Upper shell contact surface and lower house contact surface are provided with intermeshing concavo-convex shallow slot.
Can reach following beneficial effect after adopting technique scheme: the upper shell material of the utility model tractor cab overhead type defrosting heater unit is the engineering plastics injection mo(u)lding of high-and low-temperature resistance; The material of warm braw core body is that rubber and plastic, aluminum pipe, aluminium ripple, iron plate withholding form; The material of lower house is the engineering plastics injection mo(u)lding of high-and low-temperature resistance, light practicality.It is rational in infrastructure, has solved the frosting problem of tractor cab front glass effectively, does not influence the heating of chaufeur simultaneously again, and driver vision is unaffected, operates more nimble.
Description of drawings
Fig. 1 is the utility model tractor cab overhead type defrosting heater unit contour structures scheme drawing.
Fig. 2 is the utility model tractor cab overhead type defrosting heater unit heating status architecture scheme drawing.
Fig. 3 is the utility model tractor cab overhead type defrosting heater unit defrosting and heating structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.Shown in Fig. 1～3, tractor cab overhead type defrosting heater unit comprises: motor assembly 1, warm braw core body 2, upper shell 3, lower house 4, air door 5, air damper controller 6; Motor assembly 1 is contained in the semicircle spiral case of lower house 4; Warm braw core body 2 is contained in the groove of lower house 4 middle parts, and air door 5 is contained in the air outlet inboard, and air damper controller 6 is contained in the air outlet outside; Dock with the main shaft of air door 5; Upper shell 3 contact surfaces and lower house 4 contact surfaces are provided with intermeshing concavo-convex shallow slot, and upper shell 3 contact surfaces closely are buckled on lower house 4 contact surfaces, and connecting bore is used the screw fit sealing all around.
As can beappreciated from fig. 2, after motor assembly 1 energising, the motor rotation is given warm braw core body 2 air in the operator's compartment, and air becomes hot blast through warm braw core body 2, gets back to operator's compartment again from the air outlet of heater unit.Air door 5 is in the position that A is ordered at this moment, and the defrosting air port is closed, and supplies cab heating to use.
As can beappreciated from fig. 3, after air damper controller 6 energisings, air door 5 forwards the B point to by the A point; Open in the defrosting air port; Hot blast behind the air process warm braw core body 2, a part is got back to operator's compartment again from the air outlet of heater unit, and a part is come out through defroster; The trac. front glass is defrosted, and this state defrosting, heating are carried out simultaneously.
The utility model is simple in structure, easy to use, and defrosting, heating are neglected neither; Both solved the frosting problem of tractor cab front glass; Solved driver vision and the unhandy problem of influencing again.
