Referring to fig. 1, fig. 1 is a schematic view of a magnetron air cooling structure of a heating furnace according to an embodiment of the present invention, the present invention provides a magnetron air cooling structure of a heating furnace, a furnace body 10 is disposed in the heating furnace, a magnetron 50 is disposed outside the furnace body 10, and the magnetron 50 air cooling structure includes a fan 60, an air guide cover 20 and a main air inlet cover 30 disposed outside the furnace body 10; a main air duct 21 is formed inside the air guiding cover 20, the magnetron 50 is arranged in the main air duct 21, a main air inlet duct 31 is formed inside the main air inlet cover 30, and the main air duct 21 is communicated with the main air inlet duct 31; the fan 60 drives the airflow to sequentially pass through the main air inlet duct 31 and the main air duct 21 and then output to the outside of the furnace body 10. When cold airflow flows along the main air duct 21, the cold airflow acts on the magnetron 50 to cool the magnetron 50.
When the air conditioner is installed, a cooling mechanism, such as an electronic ice liner and the like, can be arranged in the main air inlet cover 30 or the main air duct 21, so that the temperature of air flow entering the main air duct 21 is relatively low, and a better cooling effect can be achieved.
Because the magnetron 50 is arranged on the main air duct 21 and the main air inlet cover 30 is connected with the air guide cover 20, the main air inlet duct 31 and the main air duct 21 are arranged independently, the main air inlet cover 30 and the air guide cover 20 can be conveniently arranged according to the external structure of the furnace body 10, the design of the external space of the furnace body 10 can be adapted, and the external space of the furnace body 10 can be fully utilized.
The fan 60 may be disposed at one side of the main air inlet cover 30, so that the fan 60 draws the air flow into the main air inlet duct 31, the air flow is conveyed into the main air duct 21 along the main air duct 21, cools the magnetron 50, and is output from one end of the wind scooper 20 away from the main air inlet cover 30; the fan 60 can also be disposed at an end of the wind scooper 20 close to the main wind inlet cover 30, and in an embodiment of the present invention, the fan 60 is disposed at an end of the wind scooper 20 away from the main wind inlet cover 30.
When the main air inlet cover 30 and the air guide cover 20 are arranged, the cross sectional area of one end, away from the air guide cover 20, of the main air inlet cover 30 is larger than that of the inside of the air guide cover 20 at the position of the magnetron 50, when air flow enters the main air duct 21 from the main air inlet duct 31, when the air flow flows to the magnetron 50, the cross sectional area is reduced, the air flow velocity is increased, and the cooling efficiency can be improved. Or the cross-sectional area of the main air inlet hood 30 can be gradually reduced along the airflow flowing direction, so as to increase the flow speed of the airflow in the air guiding hood 20.
Referring to fig. 1, in an embodiment of the present invention, the main air inlet hood 30 is a rectangular parallelepiped structure, one end of the wind scooper 20 close to the main air inlet hood 30 is a fan-shaped structure, and the cross-sectional area of the main air duct 21 gradually decreases along the airflow flowing direction, so as to increase the airflow speed. When the main air inlet cover 30 is designed, a plurality of groups of through holes are uniformly distributed at one end of the main air inlet cover 30 close to the air guide cover 20, so that air flow can enter the air guide cover 20 through the main air inlet cover 30.
When the main air inlet cover 30 and the air guide cover 20 are installed, one end, far away from the air guide cover 20, of the main air inlet cover 30 can be arranged on the front panel 11 or the side panel of the heating furnace, and meanwhile, one end, far away from the main air inlet cover 30, of the air guide cover 20 can be arranged on the rear panel 12 of the heating furnace, so that the air flow input end of the main air inlet cover 30 and the air flow output end of the air guide cover 20 are arranged in a staggered mode, and further, air flow output by the air guide cover 20 is prevented from entering the main air inlet cover 30 again.
Referring to fig. 1, in order to improve the heating efficiency of the heating furnace, in an embodiment of the present invention, two magnetrons 50 are disposed outside the furnace body 10, and the two magnetrons 50 are disposed at an end of the main air duct 21 away from the main air intake hood 30. At this time, the air flow in the air guiding cover 20 acts on the two magnetrons 50 at the same time, so as to realize the synchronous cooling of the two magnetrons 50.
By arranging two magnetrons 50, the heating efficiency of the heating furnace can be improved, and the time for processing food can be shortened. In this embodiment, the wind scooper 20 is simultaneously used for two magnetrons 50, so that the cooling effect can be simultaneously achieved, the design of the cooling structure of the magnetrons 50 is simplified, and the space utilization rate of the heating furnace is improved.
In another embodiment of the present invention, two sets of the fans 60 are disposed on the wind scooper 20; the two sets of fans 60 respectively correspond to the two magnetrons 50, so that the two sets of fans 60 respectively drive the air flow to pass through the two magnetrons 50 and then output the air flow to the outside of the furnace body 10. The two sets of fans 60 respectively drive air to flow towards the corresponding magnetrons 50, so as to realize the cooling of the corresponding magnetrons 50.
When only a single magnetron 50 is operated, only the fan 60 corresponding to the magnetron 50 can be started, and at this time, the air flow can be intensively acted on the magnetron 50 in the starting state, so that the air flow utilization rate is high.
Referring to fig. 2, fig. 2 is a cross-sectional view of an internal structure of a magnetron air cooling structure of a heating furnace according to an embodiment of the present invention, in an embodiment of the present invention, the heating furnace is provided with a controller 15, and the main air inlet cover 30 is disposed between the controller 15 and the furnace body 10. The furnace body 10 and the controller 15 are isolated from each other by adopting the main air inlet cover 30, so that the influence of heat generated when the furnace body 10 is opened on the normal operation of the controller 15 can be avoided.
When the main air inlet cover 30 is arranged, a heat insulation cavity 32 can be arranged between the main air inlet cover 30 and the furnace body 10, and the main air inlet cover 30 is separated from the furnace body 10 through the heat insulation cavity 32, so that the air flow sucked by the main air inlet cover 30 is prevented from being heated due to the heat generated by the furnace body 10 when the furnace body 10 is opened; in another embodiment of the present invention, a heat insulation cushion layer is disposed in the heat insulation cavity 32, and the heat insulation cavity 32 may be filled with a heat insulation material to form a heat insulation cushion layer, so as to further achieve a heat insulation effect.
Because the controller 15 generates a certain amount of heat during operation, when cold air enters the main air duct 21 through the main air inlet duct 31, a certain cooling effect can be exerted on the controller 15, and thus the controller 15 can be prevented from overheating.
Through the design mode, when the magnetron 50 is cooled, the controller 15 can be synchronously cooled, and further a cooling system of the controller 15 is not required to be independently designed, so that the overall design of the heating furnace is simplified, and the internal space of the heating furnace is fully utilized.
The shape of the main air inlet cover 30 can be matched with the shape of the controller 15, and the surface of one end, facing the controller 15, of the main air inlet cover 30 can be set to be a plane, so that the surface of one end, facing the furnace body 10, of the main air inlet cover 30 is mutually attached to the surface of one end, facing the controller 15, of the furnace body 10, and the contact area between the main air inlet cover 30 and the controller 15 is increased. In another embodiment of the present invention, the controller 15 is attached to the outer wall of the main air inlet hood 30 at the end close to the air guiding hood 20, the cross-sectional area of the middle of the main air inlet duct 31 is larger than the cross-sectional area of the main air inlet duct 31 at the end close to the air guiding hood 20, when the air flow flows along the main air inlet duct 31, the flow velocity of the air flow is gradually increased, so that when acting on the side wall of the main air inlet hood 30 at the end close to the air guiding hood 20, the cooling effect on the side wall of the main air inlet hood 30 can be better, the air flow can be better acted on the controller 15, and when the flow velocity of the air flow is increased, the better cooling effect can be achieved on the controller 15.
Referring to fig. 1, fig. 2 and fig. 3, fig. 3 is a schematic structural view of a wind scooper and an auxiliary wind inlet cover according to an embodiment of the present invention, in an embodiment of the present invention, an auxiliary wind inlet cover 40 is disposed at an end of the wind scooper 20 close to the main wind inlet cover 30, and an auxiliary wind inlet duct 41 is formed in the auxiliary wind inlet cover 40; the secondary air inlet duct 41 is communicated with the main air duct 21, and air flows respectively enter the main air duct 21 through the main air inlet duct 31 and the secondary air inlet duct 41. By arranging the main air inlet duct 31 and the sub air inlet duct 41 at the same time, cold air flow can be input from a plurality of inlets, and a better cooling effect can be achieved.
When the positions of the main air inlet cover 30 and the auxiliary air inlet cover 40 are set, the main air inlet cover 30 and the auxiliary air inlet cover 40 can be dispersedly arranged at the end far away from the air guiding cover 20, and when the fan 60 runs, the airflow is input into the air guiding cover 20 from the dispersing direction.
When the air flow is input into the air guiding cover 20 through the main air inlet cover 30 and the auxiliary air inlet cover 40, the cross-sectional area of the main air duct 21 is smaller than the sum of the cross-sectional areas of the main air inlet duct 31 and the auxiliary air inlet duct 41, so that the flow speed of the air flow entering the main air duct 21 is increased, and the cooling efficiency of the magnetron 50 is improved.
When the fan 60 is installed, the fan 60 may be disposed on the wind scooper 20, or the fans 60 may be disposed on the main wind scooper 30 and the auxiliary wind scooper 40, respectively. The secondary air inlet hoods 40 can be a plurality of groups arranged on the air guide hood 20 to realize dispersed air flow input.
Since the interior of the furnace body 10 of the heating furnace is generally provided with the illuminating lamp, and the lamp control box 19 of the lamp body is easily heated to increase the temperature during the operation of the lamp body, in one embodiment of the invention, the lamp control box 19 is arranged outside the furnace body 10, and the air flow enters the secondary air inlet duct 41 through the lamp control box 19. One end of the secondary air inlet cover 40, which is far away from the air guiding cover 20, can extend to the lamp control box 19, so that the lamp control box 19 is positioned on the airflow channel of the secondary air inlet cover 40.
When the fan 60 operates, the air flow acts on the lamp control box 19, and the effect of cooling the lamp control box 19 can be achieved. When the fan 60 operates, the airflow in the secondary air inlet duct 41 can act on the lamp control box 19 and the magnetron 50 to cool different parts, and the same fan 60 can be used to achieve the above effects at the same time, thereby being helpful to reduce the number of cooling fans 60 arranged outside the heating furnace and simplifying the structural design of the heating furnace.
When the fan 60 operates, the main air inlet cover 30 can simultaneously perform a cooling effect on the control box, the auxiliary air inlet cover 40 can simultaneously perform a cooling effect on the lamp control box 19, and air flows in the main air inlet cover 30 and the auxiliary air inlet cover 40 can simultaneously converge to the air guide cover 20 and simultaneously act on the magnetron 50, so that the magnetron 50 is cooled, synchronous cooling of internal controls of the heating furnace is realized, the internal structural design of the heating furnace is simplified, the utilization rate of the internal space of the heating furnace is improved, and the volume of the part, which is not the furnace body 10, in the heating furnace is reduced.
With continuing reference to fig. 1 and 4, fig. 4 is a schematic view of a lamp control box mounting structure of a heating furnace according to an embodiment of the present invention, in an embodiment of the present invention, the heating furnace is provided with a housing 13, and the furnace body 10 is disposed in the housing 13; a gap is formed between the outer shell 13 and the outer wall of the furnace body 10, and the lamp control box 19 is arranged in the gap between the outer shell 13 and the furnace body 10. By providing a gap between the outer shell 13 and the outer wall of the furnace body 10, the furnace body 10 can be insulated conveniently, the heating furnace outer shell 13 is prevented from overheating, and a heat insulation cushion layer can be filled between the outer shell 13 and the furnace body 10.
Because the lighting lamp bodies inside the furnace body 10 are generally symmetrically arranged, in the present scheme, the auxiliary air inlet covers 40 can be symmetrically arranged on two sides of one end of the air guide cover 20 close to the main air inlet cover 30, so that the symmetrically arranged auxiliary air inlet covers 40 form two groups of auxiliary air inlet ducts 41, and when air flow enters the main air duct 21 through the two groups of auxiliary air inlet ducts 41, the air flow simultaneously acts on the lamp control boxes 19 on two sides, thereby realizing the synchronous cooling of the lamp control boxes 19.
Referring to fig. 4, in order to facilitate the arrangement of the main air inlet cover 30 and the auxiliary air inlet cover 40, in an embodiment of the present invention, the heating furnace is provided with a front panel 11, and the front panel 11 is provided with a main air inlet 16 and an auxiliary air inlet 17; the main air inlet duct 31 is communicated with the main air inlet 16; the secondary air inlet 17 is communicated with the gap, and the air flow entering the secondary air inlet 17 is input into the secondary air inlet duct 41 through the gap. At this time, the inlet portions of the main inlet cowl 30 and the sub inlet cowl 40 are separated from each other to realize the input of the cool air flow from different directions.
Because a large amount of space is arranged on the heating furnace, when the main air inlet 16 and the auxiliary air inlet 17 are arranged, the main air inlet 16, the auxiliary air inlet 17 and other controls can share the main air inlet 16 or the auxiliary air inlet 17, for example, the auxiliary air inlet 17 is used as an air inlet of an air cooling structure of a frequency converter of the heating furnace, so that the effect of simplifying the design is realized.

When the furnace door 18 is opened, due to the high temperature inside the furnace body 10, at the moment of opening the furnace door 18, the hot air flows outwards from the position of the furnace door 18, which easily causes water mist on the control panel 14. The air outlet 70 of the main duct 21 may be disposed on the rear panel 12 opposite to the front panel 11 to prevent the hot air from forming a mist on the control panel 14.
Because the main air inlet 16 is arranged between the oven door 18 and the control panel 14, under the action of the fan 60, the inside of the main air inlet cover 30 is in a negative pressure state, air flow can flow into the main air inlet pipe cover, when the oven door 18 is opened, the air flow can be sucked into the main air inlet cover 30 when flowing through the main air inlet 16, and the problem of water mist formation on the control panel 14 is further reduced.
