In order to overcome the deficiency of prior art, the utility model provides the warm case of hot air type of a kind of heat production efficient height, long service life.
In order to achieve the above object, the technical scheme that the utility model adopted is following:
A kind of hot air type warms up case, comprises casing, control circuit and hot air apparatus, and said hot air apparatus comprises motor, is arranged at the hot blast chamber in the motor outside, is arranged at indoor fan of hot blast and heat-generating pipe; Said fan and electromechanics are in transmission connection; Said heat-generating pipe, motor electrically connect with control circuit respectively; Said hot blast chamber is provided with air outlet.
Preferably, said hot blast chamber comprises intermediate hsg and air-out dividing plate, and said intermediate hsg is between motor and fan, and said fan, heat-generating pipe are between intermediate hsg and air-out dividing plate; The outer peripheral edges of the outer peripheral edges of said intermediate hsg, air-out dividing plate are connected with the inwall of casing.Intermediate hsg and air-out dividing plate can be made by thermal insulating material.
Preferably, said hot air apparatus is positioned at the inside top of casing.The warm case of said hot air type also comprises two ventilative dividing plates, and two ventilative dividing plates lay respectively at the both sides of box house, forms a space between ventilative dividing plate and the casing; One end of ventilative dividing plate is connected with the bottom outside of hot blast chamber, and the other end is connected with the bottom inside of casing; Ventilative dividing plate is provided with a plurality of ventilative through holes.When hot blast when air outlet blows out, hot blast gets into from the ventilative through hole on top, the ventilative through hole from the bottom blows out again, has strengthened the hot air circulation effect of box house, thereby makes the hot blast in the casing more even, be positioned at casing food be heated more even.
Preferably, said heat-generating pipe is the annular arrangement heating resistor.Said fan is positioned at the middle part of annular arrangement heating resistor.
Preferably, the bottom of said casing is provided with crashproof adhesive tape, bumps to prevent the casing and the external world, damages inner structure.
The utility model is compared with prior art separated motor and fan through the hot blast chamber, and the hot blast of backflow can not have influence on the running of motor, heat production efficient is provided and has prolonged service life of motor; Moreover it is indoor that fan and heat-generating pipe are in same hot blast, not only can directly produce hot blast, and the heat of generation is put together, and gets into box house, further improved heat production efficient, can guarantee that food obtains good insulation environment.
