Description
Technical field
The utility model relates to a kind of motor radiating technology of food processor, specifically a kind of anti-air-return cooling mechanism of food processor.
Background technology
On market, the electric motor cooling duct structure of existing food processor mainly adopts the mode of centrifugal cooling wind blade air channel structure and axial cooling wind blade air channel structure to cool motor.Adopting above two kinds of air channel structures to carry out cooling to motor can cause cooling air at enclosure interior chaotic flow, thus cause a large amount of wind toward the top crossfire of motor, cool insufficient, cooling-down effect is undesirable, also very large noise be can produce, useful life and the performance of motor affected further.Patent Office of the People's Republic of China was on 05 30th, 2012 Granted publications, the patent No. is " a kind of cooling body of motor for domestic food processor " of " 200910208666.5 ", it comprises: housing, be arranged on the motor in housing, to be arranged on below motor and by the cooling wind blade of motor-driven rotation, also to include cover body, cover on the periphery of described motor and cooling wind blade, be seated on described base plate, form tubbiness inner chamber with base plate; The bottom of described inner chamber has the air channel arranged along inner chamber perisporium tangential direction, and the tail end in air channel is provided with the exhaust outlet that the hot blast produced by cooling motor discharges described inner chamber; Described cooling wind blade is centrifugal cooling wind blade, and it is fixed on the baffle plate that is positioned at below it, and described baffle plate is by motor-driven rotation; The top of described housing is provided with ventilation hole.Although it is provided with flange at the inwall of cover body, prevent cooling wind blade side return air, the upper surface that air-flow is running into flange stops, still can produce return air and crossfire.
Summary of the invention
The purpose of this utility model is defect for above-mentioned prior art and deficiency, and for people provide a kind of motor full and uniform cooling, structure is simple, noise is low, the cooling mechanism of good heat dissipation effect, for food processor.
For achieving the above object, technical solution adopted in the utility model is: the anti-air-return cooling mechanism of this food processor, it comprises base, housing, in housing, motor is installed, this motor is fixed in housing by support, and the bottom of motor is provided with by motor-driven cooling wind blade, and described base offers air outlet, this air outlet is positioned at air draft place of cooling wind blade, and housing offers air inlet; The outside of described motor, support and cooling wind blade is provided with ventilating duct, wind gap is left between ventilating duct and motor, air is along air inlet, wind gap, air outlet one-way flow, described ventilating duct internal diameter outside cooling wind blade increases, and forms a circle choked flow step above cooling wind blade.
It is curved that described choked flow step place is provided with the return air being tilted to arc lower extension, the interior walls be smooth transition of the upper surface that return air is curved and ventilating duct.
Described ventilating duct is that integral type or many bodies are combined to form.
Described ventilating duct is fixed by screws on base.
The utility model air, along air inlet, wind gap, air outlet one-way flow, prevents enclosure interior chaotic flow, can ensure that fresh air can arrive motor fast, carry out heat exchange with motor, and hot-air can be discharged fast simultaneously.Ventilating duct internal diameter increases can reduce the air-flow of cooling wind blade surrounding and ventilating duct inwall clashes into and produces sinuous flow.Choked flow step and the curved backflow outside cooling wind blade and the crossfire of preventing of return air enter housing, and these backflows and crossfire are rebooted cooling wind blade, then discharge via air outlet, thus realize the full and uniform cooling of motor.The interior walls be smooth transition of the upper surface that return air is curved and ventilating duct, therefore air-flow can not clash into curved generation of return air, thus prevents backflow and the generation of crossfire, has that structure is simple, noise is low, the advantage of good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model first embodiment.
Fig. 2 is the structural representation of the utility model second embodiment.
Embodiment
As shown in Figure 1, the utility model is a kind of anti-air-return cooling mechanism of food processor, and its first embodiment comprises base 4 and housing 3, is provided with motor 2 in housing 3, and this motor 2 is fixed in housing 3 by support 1.The bottom of motor 2 is provided with the cooling wind blade 7 driven by motor 2, and described base 4 offers air outlet 9, and this air outlet 9 is positioned at air draft place of cooling wind blade 7, and housing 3 offers air inlet.When motor 2 works, cooling wind blade 7 synchronous axial system, takes away the heat that motor 2 produces.The outside of described motor 2, support 1 and cooling wind blade 7 is provided with ventilating duct 6, and described ventilating duct 6 is fixed on base 4 by screw 10.Wind gap 5 is left between ventilating duct 6 and motor 2, air, along air inlet, wind gap 5, air outlet 9 one-way flow, which prevent the inner chaotic flow of housing 3, can ensure that fresh air can arrive motor 2 fast, carry out heat exchange with motor 2, and hot-air can be discharged fast simultaneously.Described ventilating duct 6 internal diameter outside cooling wind blade 7 increases, and forms a circle choked flow step 8 above cooling wind blade 7.The increase of ventilating duct 6 internal diameter can reduce cooling wind blade 7 surrounding air-flow and ventilating duct 6 inwall clashes into and produces sinuous flow.Choked flow step 8 can prevent the backflow outside cooling wind blade 7 and crossfire from entering housing 3, and these backflows and crossfire are rebooted cooling wind blade 7, then discharges via air outlet 9, thus realizes the full and uniform cooling of motor 2.Described ventilating duct 6 is combined to form for integral type or many bodies, is therefore made up of and the utility model analog structure two or more parts, also belongs to protection range of the present utility model.
Second embodiment of the present utility model adds return air curved 11 on the basis of the first embodiment, described return air curved 11 extends to form for being tilted to arc lower at choked flow step 8 place, there is the setting of return air curved 11, backflow outside cooling wind blade 7 and crossfire are more easily directed to cooling wind blade 7, then discharge via air outlet 9.The upper surface of return air curved 11 and the interior walls be smooth transition of ventilating duct 6, therefore air-flow can not produce with return air curved 11 and clash into, thus prevents backflow and the generation of crossfire, has that structure is simple, noise is low, the advantage of good heat dissipation effect.
