Specific embodiment

Further to illustrate that the application is the technical means and efficacy reaching predetermined purpose of utility model and being taken, below Specific embodiment, structure, feature and its effect according to the application are described in detail such as in conjunction with attached drawing and preferred embodiment Afterwards.In the following description, what different " embodiment " or " embodiment " referred to is not necessarily the same embodiment.In addition, one or more Special characteristic, structure or feature in a embodiment can be combined by any suitable form.

In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, the utility model proposes a kind of ovens of easy heat radiation, comprising: by bottom plate 12 and encloses It is located at the pedestal 1 that four blocks of side plates 13 of 12 4 periphery of bottom plate are constituted；Baking cavity 2 on pedestal 1, the bottom of the pedestal 1 are set Power supply accommodating space 11 is formed between plate 12, side plate 13 and the bottom face for toasting cavity 2, is equipped with electricity in the power supply accommodating space 11 Source module 5, the power module 5 are mounted on bottom plate 12, and bottom plate 12 has the air inlet 121 of connection power supply accommodating space 11； It is placed in the hot wind component 3 being set on the cavity backboard of baking cavity 2, which is used to the inside of baking cavity 2 provide Hot wind；Cladding is arranged in 3 outside of hot wind component and is fixed on the rear cowl 4 of cavity backboard lateral surface, the rear cowl 4 and hot wind group There is heat-dissipating space 40, and the rear cowl 4 is equipped with hot-blast outlet 41 and cold wind import 42 between part 3；Wherein the one of pedestal 1 Block side plate 13 is equipped with axial flow blower 6, and the air intake vent of the axial flow blower 6 is connected to power supply accommodating space 11, which goes out Air port is connected to heat-dissipating space 40.

Hot wind component 3 in oven is the prior art.In general, hot wind component 3 includes: for generating baking heat Heater, the motor 31 that heat is blown into the blade of baking cavity 2 and is used to rotate with movable vane piece for generating air-flow flowing, And blade is fixed on 31 turns of thes tip of the axis of motor.Heater, which is powered on, to give off heat, and air is thermally formed hot-air, and electric The shaft of machine 31 rotates with movable vane piece hot-air being blown into baking cavity 2 to toast to the food in baking cavity 2.

Motor 31 is fixed on the cavity backboard of baking cavity 2 as a part of hot wind component 3, and motor 31 is positioned at scattered In heat space 40.And motor 31 can generate heat during the work time, therefore, carry out heat dissipation to motor 31 and be to ensure that hot wind component One of the technological means of 3 energy reliably workings.The utility model radiates to motor 31 using 2 approach: first is that on rear cowl 4 Equipped with hot-blast outlet 41 and cold wind import 42, cold air can enter heat-dissipating space 40, the cold air band leakage of electricity from cold wind import 42 The partial heat of the generation of machine 31 is simultaneously discharged from the hot-blast outlet of rear cowl 4 41, plays by natural heat dissipation mode to motor 31 Certain heat dissipation effect；Second is that reinforce heat dissipation effect according to the work of axial flow blower 6, and when axial flow blower 6 is opened, sucking electricity It is drained into heat-dissipating space 40 by the air in source accommodating space 11, on the one hand can allow power supply accommodating space 11 air pressure reduce to External cold air can be sucked into power supply accommodating space 11 by air inlet 121, cold air can take away power supply accommodating space The heat of power module 5 is in 11 to ensure the functional reliability of power module 5, on the other hand since the effect of axial flow blower 6 makes 40 air pressure of heat-dissipating space, which increases so that air be accelerated to flow through motor 31, allows hot-air to accelerate to be discharged from hot-blast outlet 41, therefore, this Utility model is played by adding axial flow blower 6 while the heat spreading function to power module 5 and motor 31.

Furthermore, it is understood that hot-blast outlet 41 is situated so as to hot-air discharge close to motor 31.Also, motor 31 is located at axis Between the air outlet and hot-blast outlet 41 of flow fan 6, thus allow cold air have to pass through motor 31 could from hot-blast outlet 41 with Ensure to provide heat dissipation to motor 31.

Furthermore, it is understood that in order to ensure the heat-sinking capability to power module 5, power module 5 is fixed on bottom plate 12 and Power module 5 is between axial flow blower 6 and air inlet 121.Such setting allows power module 5 to be located at the entrance of air inlet 121 On cold air to the inlet air flow path of axial flow blower 6, to enter cold air from air inlet 121 when axial flow blower 6 being allowed to work Inherently flow through the surface of power module 5.Certainly, the quantity of air inlet 121 is also possible to multiple.For example, in one embodiment In, one or more air inlets 121 are equipped with close to four peripheries of power module 5 on bottom plate 12.

In one embodiment, 1 bottom of pedestal is additionally provided with support leg 14.The support leg 14 makes the bottom plate Air inlet 121 on 12 is easier to suck cold air from the external world.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
