Referring to fig. 1, 2, 6 and 8, in the present embodiment, the cooking apparatus includes a cabinet 100, an air duct case 300, a frequency converter 400, a magnetron 500 and a heat radiation fan 600; the box body 100 is internally provided with a cooking cavity 110 for cooking food and an electric control cavity 120 positioned at the top of the cooking cavity 110, and the box body 100 is provided with an air inlet 130 communicated with the electric control cavity 120; the air duct shell 300 is arranged in the electric control cavity 120, an air duct air inlet 310 and an air duct air outlet 320 are arranged on the air duct shell 300, and a heat dissipation air duct 330 communicated between the air duct air inlet 310 and the air duct air outlet 320 is arranged in the air duct shell 300; the frequency converter 400 is disposed in the heat dissipation air duct 330; at least part of the magnetron 500 is disposed in the heat dissipation air duct 330; the heat dissipation fan 600 is disposed in the electric control cavity 120, a fan air inlet 620 of the heat dissipation fan 600 is communicated with the electric control cavity 120, a fan air outlet 630 of the heat dissipation fan 600 is communicated with the air duct air inlet 310, and the heat dissipation fan 600 is used for promoting the air flow outside the box 100 to flow out of the box 100 from the air duct air outlet 320 after sequentially flowing through the air inlet hole 130, the electric control cavity 120 and the heat dissipation air duct 330.

Since the cooking apparatus of the present embodiment has the air duct case 300 and the heat dissipation fan 600 that can commonly dissipate heat from the inverter 400 and the magnetron 500, the heat dissipation fan 600 can also introduce the air flow outside the cooking apparatus into the electric control chamber 120 to dissipate heat from the electric control chamber 120. Therefore, the cooking apparatus of the present embodiment can radiate heat for the frequency converter 400 and the magnetron 500 of the cooking apparatus only by providing one air duct case 300 and one heat radiation fan 600, and simultaneously radiate heat for the electric control chamber 120, so that the air duct case 300 and the heat radiation fan 600 occupy as little space of the electric control chamber 120 as possible, and the production cost of the cooking apparatus is effectively reduced.

In addition, it should be noted that a heat dissipation mechanism allowing airflow to flow through is disposed on the frequency converter 400 or the magnetron 500, or a gap allowing airflow to flow through is disposed between the frequency converter 400 and the air duct case 300 and between the magnetron 500 and the air duct case 300, so that the airflow can take away heat on the frequency converter 400 and the magnetron 500, and heat dissipation of the frequency converter 400 and the magnetron 500 is achieved.

In addition, in the prior art, since the microwave oven is provided with a plurality of heat dissipation systems, namely a plurality of heat dissipation fans 600 are arranged, when the heat dissipation systems work, a great amount of noise can be generated when the heat dissipation fans 600 rotate, and the experience of a user using the microwave oven is affected.

Furthermore, the cooking device of the present embodiment can satisfy the heat dissipation of the cooking device by only providing one heat dissipation fan 600. Accordingly, the cooking apparatus of the present embodiment effectively reduces noise due to the arrangement of the plurality of heat radiation fans 600.

Referring to fig. 8, in the present embodiment, the heat dissipation air duct 330 includes a variable frequency air duct 331 and a magnetic control air duct 332 separated by a partition 340, and a magnetic control port 350 communicating with the magnetic control air duct 332 is provided on the air duct case 300, the frequency converter 400 is accommodated in the variable frequency air duct 331, the magnetron 500 is disposed on the magnetic control port 350 in a penetrating manner, and at least part of the magnetron 500 is accommodated in the magnetic control air duct 332.

It can be appreciated that, since the air flow sent by the heat dissipation fan 600 can be separated by the partition 340 and flow through the frequency converter 400 and the magnetron 500 respectively, the frequency converter 400 and the magnetron 500 can be cooled respectively, and the situation that the heat dissipation effect of the frequency converter 400 and the magnetron 500 is affected due to the channeling between the air flows flowing through the frequency converter 400 and the magnetron 500 is effectively avoided.

In addition, by arranging the magnetic control port 350, at least part of the magnetron 500 can be accommodated in the magnetic control air duct 332, that is, the magnetron 500 can be allowed to only arrange the part needing heat dissipation into the heat dissipation air duct 330 for heat dissipation, and further the size of the air duct shell 300 can be further reduced, and the production cost of the cooking equipment is reduced.

Referring to fig. 8, in the present embodiment, an air inlet end of the variable frequency air duct 331 and an air inlet end of the magnetic control air duct 332 are connected in parallel and then are communicated with the air duct air inlet 310; the air outlet end of the variable frequency air duct 331 and the air outlet end of the magnetic control air duct 332 are connected in parallel and then communicated with the air duct air outlet 320. That is, the two ends of the partition 340 do not extend to the air duct inlet 310 and the air duct outlet 320 of the heat dissipation air duct 330, so that the disturbance of the partition 340 to the air flow entering the heat dissipation air duct 330 and flowing out of the heat dissipation air duct 330 is avoided, and the air inlet efficiency of the air flow flowing into the heat dissipation air duct 330 and the air outlet efficiency of the air flow flowing out of the heat dissipation air duct 330 are ensured.

Referring to fig. 7, in the present embodiment, the height of the magnetron air tunnel 332 is higher than the height of the variable frequency air tunnel 331.

On the one hand, the height of the magnetic control air duct 332 is higher than that of the variable frequency air duct 331, so that the space and heat dissipation requirements of the magnetron 500 and the frequency converter 400 can be met, on the other hand, the structure that the height of the magnetic control air duct 332 is higher than that of the variable frequency air duct 331 can form a bent ladder between the magnetic control air duct 332 and the variable frequency air duct 331, and further wind channeling between the magnetic control air duct 332 and the variable frequency air duct 331 can be avoided, and the heat dissipation effect on the frequency converter 400 and the magnetron 500 is guaranteed.

Referring to fig. 6, in the present embodiment, a frequency converter 400 is disposed in a left region of the electric control chamber 120; the magnetron 500 is connected to the middle bottom of the electric control chamber 120, and the magnetron 500 is extended to the front of the frequency converter 400; the heat radiation fan 600 is disposed at the rear of the inverter 400 and the magnetron 500. The frequency converter 400, the magnetron 500 and the heat radiation fan 600 can be arranged in the left area of the electric control cavity 120 in a concentrated manner, and can be arranged in the air duct shell 300 in a concentrated manner, so that the air duct shell 300 can have a smaller size, occupies a smaller space of the electric control cavity 120, and reduces the production cost of the cooking equipment.

In addition, the frequency converter 400, the magnetron 500 and the heat dissipation fan 600 can be arranged in the left area of the electric control cavity 120 in a concentrated manner, so that the electric control cavity 120 has a larger space capable of allowing airflow to flow in the space and has smaller wind resistance to airflow in the electric control cavity 120, and the heat dissipation effect of the heat dissipation fan 600 on the electric control cavity 120 can be ensured.

Referring to fig. 2, 3 and 5, in the present embodiment, since the frequency converter 400, the magnetron 500 and the heat radiation fan 600 may be intensively disposed at the left region of the electric control chamber 120, in case the cooking apparatus is a steaming and baking integrated machine, the cooking apparatus further includes a water storage box 700; the water storage box 700 is disposed at the right region of the electric control chamber 120. The foregoing layout of the frequency converter 400, the magnetron 500 and the heat dissipation fan 600 in the electric control chamber 120 can reserve a larger space for the water storage box 700 for realizing the steaming function, so as to ensure the normal operation of the cooking device, namely the steaming and baking integrated machine.

Referring to fig. 3, 4 and 5, in the present embodiment, the air duct case 300 extends in the front-rear direction, and the air duct outlet 320 faces the front of the case 100, so as to adapt to the foregoing layout of the frequency converter 400, the magnetron 500 and the heat dissipation fan 600 in the electric control chamber 120, to achieve heat dissipation of the frequency converter 400 and the magnetron 500, and to ensure normal operation of the cooking apparatus.

Referring to fig. 3 and 4, in the present embodiment, the duct air outlet 320 is laterally disposed to extend left and right.

It can be understood that, because the volume of the cooking device is smaller, the setting space reserved for the air duct air outlet 320 on the box 100 is smaller, so that the air duct air outlet 320 can be prolonged as much as possible in the left-right direction, so as to ensure the air outlet efficiency of the air flow; meanwhile, the air duct air outlet 320 can be made as narrow as possible and hidden at the rear side of the door body 200 of the cooking device capable of opening and closing the cooking cavity 110 and the top front panel 140 of the box body 100, so as to ensure the aesthetic property of the cooking device.

Referring to fig. 1, in the present embodiment, the air inlet 130 is located on the right side plate 150 of the case 100; the fan inlet 620 is located at the top of the fan housing 610 of the heat dissipation fan 600.

It can be appreciated that, by disposing the air inlet 130 on the right side plate 150 of the box 100, the fan air inlet 620 is disposed at the top of the fan housing 610, so that the air flow outside the cooking apparatus can flow through the electric control chamber 120 in a larger range, so as to ensure the heat dissipation effect on the electric control chamber 120.

In addition, the air inlet 130 may be directly formed on the right side plate 150, or the right side plate 150 may be formed by connecting a plurality of plates, and the air inlet 130 may be understood as a gap between the plurality of plates.

Referring to fig. 7 and 8, in the present embodiment, the heat radiation fan 600 is a centrifugal fan whose fan housing 610 is integrally provided with the duct housing 300. A fan 640 of the heat radiation fan 600 is disposed in the fan housing 610.

It is understood that the fan housing 610 and the air duct housing 300 of the heat dissipation fan 600 may be an integrally formed structure, so that the complexity of the manufacturing process of the fan housing 610 and the air duct housing 300 and the assembly complexity of the fan housing 610 and the air duct housing 300 may be reduced; in addition, the assembly parts or the connecting parts required for connecting the fan housing 610 and the air duct housing 300 are reduced, so that the overall production cost of the cooking device is further effectively reduced; and the centrifugal fan can further meet the airflow direction of the airflow flowing through the air inlet hole 130, the electric control cavity 120, the fan air inlet 620 and the heat dissipation air duct 330 in sequence, so that the wind loss of the airflow in the flowing process is reduced, the flow rate of the airflow is ensured, and the requirements and the normal operation of the heat dissipation process of the cooking equipment are ensured.

In addition, in the case that the blower housing 610 and the duct housing 300 are of a unitary structure, the blower outlet 630 may be the duct inlet 310.

In the prior art, no matter what kind of power or cooking mode is used in the oven, every cooling system's cooling fan 600 is all opened and the rotational speed of fan can't be adjusted, has caused excessive heat dissipation, extravagant electric energy, and the noise of the high rotational speed of motor is also bigger simultaneously, causes noise pollution, has reduced user experience.

In this embodiment, the cooking device may be a microwave oven, a steaming and baking all-in-one machine, or other cooking device having the features described in the above embodiments.

In this embodiment, the cooking apparatus further includes a variable frequency temperature sensor 830 and a magnetic control temperature sensor 840; the variable frequency temperature sensor 830 is disposed on the frequency converter 400, the variable frequency temperature sensor 830 is connected to the cooling fan 600, and the variable frequency temperature sensor 830 is used for detecting the temperature of the frequency converter 400; the magnetron temperature sensor 840 is arranged on the magnetron 500, the magnetron temperature sensor 840 is connected with the cooling fan 600, and the magnetron temperature sensor 840 is used for detecting the temperature of the magnetron 500; in case that the temperature detected by the variable frequency temperature sensor 830 or the temperature detected by the magnetic control temperature sensor 840 is equal to or higher than a preset temperature, the rotation speed of the heat radiation fan 600 increases; in case that both the temperature detected by the variable frequency temperature sensor 830 and the temperature detected by the magnetic control temperature sensor 840 are less than the preset temperature, the rotation speed of the heat radiation fan 600 is reduced.

In the present embodiment, the inverter 400 and the magnetron 500 are both connected to the heat radiation fan 600; in the case where the inverter 400 and the magnetron 500 are not operated, the rotation speed of the heat radiation fan 600 is one half of the maximum rotation speed thereof.

Since the cooking apparatus of the present embodiment can adjust the rotation speed of the heat dissipation fan 600 according to the working temperatures and working states of the frequency converter 400 and the magnetron 500 to meet the current heat dissipation requirement of the cooking apparatus, specifically, when the temperature detected by the frequency conversion temperature sensor 830 or the temperature detected by the magnetic control temperature sensor 840 is greater than or equal to the preset temperature, the rotation speed of the heat dissipation fan 600 is increased; in case that both the temperature detected by the variable frequency temperature sensor 830 and the temperature detected by the magnetic control temperature sensor 840 are less than the preset temperature, the rotation speed of the heat radiation fan 600 is reduced; in the case where the inverter 400 and the magnetron 500 do not operate, and thus the inverter 400 and the magnetron 500 do not need to radiate heat, only the electric control chamber 120 and/or the components having the steaming function are radiated, and thus the rotation speed of the radiation fan 600 can be set to be half of the maximum rotation speed thereof. Therefore, the cooking device of the embodiment avoids the occurrence of the transitional heat dissipation, avoids the waste of electric energy, saves energy, and can further reduce the noise generated by the operation of the heat dissipation fan 600 when the rotation speed of the heat dissipation fan 600 is reduced and the rotation speed of the heat dissipation fan 600 is half of the maximum rotation speed of the heat dissipation fan 600, thereby ensuring the use experience of users of the cooking device.
