[0028] The cooking appliance 100 further includes a mounting bracket 105 for fixing the fan 40 on the casing 10 of the cooking appliance 100 . It can be understood that the air outlet of the fan 40 can also be connected to the air inlet 104 through the air duct, that is to say, the installation position of the fan 40 may not be the same as the installation position of the air inlet 104, and the installation position of the fan 40 may be the first. The first side wall 101, the second side wall 102, or other cavity walls of the cooking appliance 100 are not specifically limited herein.
[0029]Preferably, the mounting bracket 105 is fixed on the second side wall 102 , and the fan 40 includes a motor 41 and an impeller 42 mounted on the motor 41 . That is, both the fan 40 and the air inlet 104 are installed on the second side wall 102 , so that the air outlet of the fan 40 can be directly communicated with the air inlet 104 . The fan 40 uses the motor 41 to drive the impeller 42 installed on the motor 41 to rotate to form fresh air, and communicates with the air inlet 104 through the air outlet of the fan 40, so that the fresh air enters the cooking cavity 30, and the high temperature water in the cooking cavity 30 is discharged. The steam and hot air are discharged out of the cooking appliance 100 through the air outlet 103 .
[0030] In the above embodiment, the air inlet 104 and the air outlet 103 are a plurality of mesh holes evenly arranged. Preferably, when the cooking utensil 100 is an oven or the like and the airtightness requirements are not very high, and the air inlet 104 and the air outlet 103 do not have other special treatments, the uniformly arranged air inlets 104 and air outlets 103 The mesh aperture is preferably 6 mm, so that when the cooking appliance 100 is cooking, the opened air inlet 104 and the air outlet 103 do not affect the cooking effect of the cooking appliance 100 .
[0031] In some embodiments, the included angle between the center line of each air inlet 104 and the inner wall of the second side wall 102 is 40°˜75°. Preferably, the included angle between the center line of each air inlet 104 and the inner wall of the second side wall 102 is 60°. Preferably, when the air outlet 103 and the air inlet 104 are a plurality of mesh holes evenly arranged, the angle between the center line of the aperture of each mesh hole and the inner wall of the second side wall 102 is 60°. Therefore, the air exhaust path can be increased by setting the relative angle position between the center line of each air inlet 104 and the second side wall 102 .
[0032] It can be understood that, so far, two ways to adjust the exhaust path have been described, including by setting the relative height positions of the air inlet 104 and the air outlet 103, and by adjusting the centerline of the air inlet 104 and the second side wall relative position between 102. The above two ways can be implemented individually or combined. In an embodiment of a combined design, along the direction perpendicular to the first side wall 101 and the second side wall 102, the air inlet 104 and the air outlet 103 are located on the same plane, and the centerline of the air inlet 104 is the same as the The included angle of the inner wall of the second side wall 102 is 40°˜75°. In an embodiment of a combined design, the air inlet 104 is located below the air outlet 103 along the vertical direction, and the angle between the center line of the air inlet 104 and the inner wall of the second side wall 102 is 40°˜75°.
[0033] In some embodiments, further special treatment can be performed on the air inlet 104 and the air outlet 103 provided on the side wall of the cooking appliance 100 . In order to increase the sealing performance of the cooking appliance 100 as a whole.
[0034] Specifically, the cooking utensil 100 further includes a cover member pivotally installed or detachably installed on the box body 10 , and the cover member can be operated to close or open the air inlet 104 and the air outlet 103 . The function of the shutter is mainly to cover and seal the air inlet 104 and the air outlet 103 when the cooking utensil 100 is cooking, and when the fan 40 is turned on after cooking, the shutter can cancel the air inlet 104 and the air outlet 103. The shielding effect of the air outlet 103 . Specifically, the shutter may be a one-way valve.
[0035] In some embodiments, the cooking appliance 100 also includes a controller. The controller can control the cooking utensil 100 to cook, and automatically start the fan 40 after the cooking is completed, so as to perform the discharge operation of high-temperature steam and hot air.
[0036] The cooking utensil 100 further includes a timing device or a temperature sensing device; the fan 40, the timing device or the temperature sensing device are all connected to the controller; the controller can control the obtained temperature data according to the preset data of the timing device or the temperature sensing device. The fan 40 is turned off or on.
[0037] Hereinafter, the shutdown of the fan 40 will be further described.
[0038] In one embodiment, after the cooking utensil 100 is finished cooking and the fan 40 is turned on, the fan 40 may be turned off through time data of the timing device or temperature data of the temperature sensing device. Specifically, the fan 40 can be turned off by the controller when the predetermined time set by the timing device is reached through the timing device of the cooking utensil 100 . The temperature in the cooking cavity 30 can also be acquired through the temperature sensing device in the cooking appliance 100, and the fan 40 can be turned off by the controller when the detected temperature is lower than the predetermined temperature.
[0039] In some embodiments, the time to turn off the fan 40 may be when the high-temperature steam or hot air in the cooking cavity 30 drops to such an extent that even if the door 20 of the cooking cavity 30 is opened, the escaped steam and hot air will not cause a risk of burns to the user fan 40 is turned off. The time for turning off the fan 40 may be preset in the timing device according to the power of the fan 40, or may be determined by the data collected by the temperature sensor. It can be understood that when only the fan 40 and the air inlet 104 and the air outlet 103 are used to process the hot air and high-temperature steam in the cooking cavity 30, when the temperature in the cooking cavity 30 has not dropped to a safe temperature, the user cannot. The door body 20 of the cooking appliance 100 is opened, so as to effectively prevent the user from being scalded by the escaping steam or hot air.
[0040] Further, in some embodiments, the time to turn off the fan 40 may be until there is no steam in the cooking cavity 30 . That is, when the high-temperature steam or hot air in the cooking cavity 30 drops to the door 20 that can open the cooking cavity 30, the door 20 can be opened. At this time, after the door 20 is opened, the hot air and steam in the cooking cavity 30 are completed. The blower 40 still works; the blower 40 and the open door body 20 can be used to remove the high-temperature steam and hot air. In this way, the steam and hot air in the cooking cavity 30 can be removed more quickly and effectively, so as to effectively solve the problem that the cooking cavity 30 is easy to condense and generate water, and the taste of the original dishes in the cooking cavity 30 can be effectively solved. Discharge to prevent odor.
[0041] To sum up, in the present application, by adding a fan 40 on the cooking appliance 100, and opening the air inlet 104 and the air outlet 103 on the cooking appliance 100, the fan 40 can be started directly after the cooking is completed, and the high temperature in the cooking cavity 30 can be locked. Water vapor and hot air are directly discharged from the air outlet 103 to prevent high temperature steam and hot air from overflowing when the user opens the door body 20, never effectively avoid contact with the user, and avoid the potential safety hazard of scalding the user. At the same time, the additional fan 40 blows fresh air into the cooking cavity 30 to quickly remove the water vapor in the cooking cavity 30 , thereby reducing the condensation of the water vapor in the cooking cavity 30 . In addition, the air blown into the cavity by the fan 40 can also be used to remove water vapor and food odor, so that the odor and water vapor are discharged with the wind flow, eliminating the residual food odor in the cooking cavity 30 and avoiding odor.
