The following description will be made taking the oven 100 as a specific example.
Referring to fig. 1 and 2, an oven 100 according to an embodiment of the present invention includes a box body 110 and a door 120, where the box body 110 can be understood as a body of the oven 100, a cooking cavity 111 is disposed in the box body 110, a front side of the cooking cavity 111 is an opening, the door 120 is connected to the front side of the box body 110 and corresponds to the opening, and a handle 121 is disposed on a surface of the door 120 to facilitate an operation of opening or closing the door 120. When the cooking device is used, food is placed in the cooking cavity 111 to be heated, and the cooking cavity 111 can be opened or closed through the door 120.
Referring to fig. 1 and 2, the cabinet 110 is provided with an electric control assembly disposed at the top outside the cooking cavity 111, the electric control assembly including a control circuit board 150 for controlling the operation of the oven 100. It can be understood that the control circuit board 150 heats up during operation, and the cooking cavity 111 radiates heat outwards during heating, so as to accelerate the temperature rise of the control circuit board 150, and the service life of the control circuit board 150 is reduced when the control circuit board is continuously at a high temperature, thereby increasing the maintenance cost of the user. Based on this, in the embodiment, the air duct structure 130 and the fan are disposed on the box body 110, the air duct structure 130 is installed in a space between a shell (not shown in the drawing) of the box body 110 and the top of the cooking cavity 111, the air duct 133 is disposed in the air duct structure 130, the control circuit board 150 is installed in the air duct 133, air outside the box body 110 is sent into the air duct 133 by the fan to form cold air, heat of the control circuit board 150 is taken away by the cold air, so that the control circuit board 150 is cooled, and stable operation of the control circuit board 150 is ensured.
Referring to fig. 1 and 2, the blower is disposed at the air inlet 131 of the air duct 133, and sends cold air from the air inlet 131 into the air duct 133, and the cold air passes through the control circuit board 150 and is discharged from the air outlet. Considering that the cold air in the air duct 133 only cools the control circuit board 150, the temperature of the cold air after heat exchange is raised, but still has a certain heat dissipation effect, if the cold air directly overflows the air duct 133 from the air outlet, the redundant cold air is not effectively utilized, waste of the cold air is caused, and the utilization efficiency of the cold air is low. Therefore, in the embodiment, the air subjected to heat exchange in the air duct 133 is discharged from the air outlet channel 112, and the air outlet area of the air outlet channel 112 is cooled, so that the surface of the door 120 can be cooled, the utilization efficiency of cold air is effectively improved, and the risk of scalding caused by touching the door 120 when the handle 121 is operated by hand is reduced.
Specifically, referring to fig. 1 and 2, the air inlet 131 of the air duct 133 is disposed at the rear side of the cabinet 110, the first air outlet 132 is disposed at the front side of the air duct 133, the air outlet channel 112 is disposed on the cabinet 110, the air outlet channel 112 is located above the door 120, and the air outlet channel 112 is communicated with the first air outlet 132, so that the air in the air duct 133 enters the air outlet channel 112 through the first air outlet 132 and is discharged out of the cabinet 110 along the air outlet channel 112. It can be understood that, when the oven 100 works, the temperature of the door 120 will rise, the fan operates to send the air outside the box body 110 into the air duct 133, under the forced convection action of the fan, an air flow is formed in the air duct 133, the air flow takes away the heat of the control circuit board 150 and then flows into the air outlet channel 112 from the first air outlet 132 in a concentrated manner, and then is discharged through the air outlet channel 112, because the air flow continuously flows out from the air outlet channel 112, the air blown out from the air outlet channel 112 still has a cooling effect, so that the air flow can take away the heat of the air outlet area, thereby playing a role of heat dissipation for the position of the.
It should be noted that the air outlet channel 112 is formed between the upper portion of the door 120 and the box body 110, and a position where the airflow can contact when being blown out along the air outlet channel 112 may be understood as an air outlet area, for example, the airflow contacts an upper end surface of the door 120, and at least a portion of the airflow diverges along an outer surface of the door 120, so that positions of the surface of the door 120 close to the air outlet channel 112 are both located in the air outlet area, and the air outlet area may also be understood as an inner side wall of the box body 110 and the door 120 extending along the air outlet channel 112 and an outer surface area close to the air outlet channel 112.
Referring to fig. 1, 2 and 3, the handle 121 is disposed at a front side of the door 120 and near the air outlet channel 112, and two ends of the handle 121 are respectively connected to the door 120 through the connection seats, so that a certain distance is formed between the middle portion of the handle 121 and the door 120, and a user can hold the handle 121 to operate the door 120 to rotate in an up-and-down direction to open or close the door 120. It can be understood that the surface of the handle 121 facing the door 120 has a projection in the front-rear direction of the cabinet 110, and it is considered that the user can easily touch the projection area 122 of the handle 121 on the door 120 when operating the handle 121. Therefore, the projection area 122 is arranged in the air outlet area, so that the temperature of the door body 120 in the projection area 122 is reduced, and the risk of scalding caused by contacting the surface of the door body 120 when a user operates the handle 121 is reduced.
The closer the projection area 122 of the handle 121 on the surface of the door 120 is to the air outlet duct 112, the better the heat dissipation effect is, and the air outlet of the air outlet duct 112 is blown out toward the outside of the box body 110, which is not limited to having the heat dissipation effect on the surface of the door 120, and for example, the air outlet may be directly blown to the handle 121 to dissipate heat and cool the handle 121. The handle 121 with different sizes or shapes is selected according to the use requirements of actual products, so that the projection area 122 of the handle 121 can be located in the air outlet area, better use experience is guaranteed, and the specific size and shape of the handle 121 are not described in detail. In addition, the air outlet channel 112 and the handle 121 are not limited to the structures shown in the above embodiments, and are designed according to the product requirements of different cooking devices, for example, the air outlet channel 112 may be disposed at the right side of the door body 120, the handle 121 is close to the right side of the door body 120, and the air outlet area of the air outlet channel 112 can cover the projection area 122 of the handle 121.
Referring to fig. 1, 2 and 3, a display module is disposed on the cabinet 110, the display module is disposed on the front side of the cabinet 110 and above the door 120, and the air duct structure 130 is disposed on the back of the display module. The display component is used for displaying and setting information such as cooking temperature, cooking time and the like, for example, the display panel can intuitively acquire the working state of the oven 100 through the display component, and user experience is improved. An air outlet channel 112 is formed between the door 120 and the display module, and the air outlet channel 112 can be understood as a gap between the door 120 and the display module in a closed state, so that the wind energy in the wind channel 133 can enter the gap through the first air outlet 132 and be discharged out of the box body 110 along the gap.
It can be understood that, referring to fig. 1, the display assembly and the door 120 have a certain length in the left-right direction of the cabinet 110, such that the air outlet channel 112 is defined between the lower end surface of the display assembly and the upper end surface of the door 120. The air outlet channel 112 and the first air outlet 132 may be directly communicated, for example, the size of the port of the first air outlet 132 is reduced to match the air outlet channel 112; for example, an air guide plate or an air guide groove is disposed at the first air outlet 132, so as to guide the air discharged from the first air outlet 132 into the air outlet channel 112, so that the wind in the air duct 133 can be blown out along the air outlet channel 112. Therefore, the cold air in the air duct 133 can dissipate heat of the electronic control assembly, and can also dissipate heat of the positions of the door 120, such as the projection area 122 of the handle 121, the outer surface of the display assembly close to the air outlet channel 112, and the like, so that the utilization efficiency of the cold air is effectively improved, and the heat dissipation effect is good.

Since the display module is disposed at the front side of the cabinet 110, the temperature of the cooking chamber 111 is increased during operation, and the temperature of the cooking chamber is also increased accordingly, so that the service life of the display circuit board 141 is also reduced in a continuous high temperature state. Therefore, in this embodiment, the cavity 142 is communicated with the first air outlet 132, and the first through hole 143 is disposed at the bottom of the control box 140, so that the cavity 142 is communicated with the air outlet channel 112 through the first through hole 143, and the air generated by the fan sequentially passes through the air duct 133, the cavity 142 and the air outlet channel 112, and is then discharged from the air outlet channel 112, and the air flow can take away the heat of the control circuit board 150 and the display circuit board 141, thereby playing an effective cooling role on the control circuit board 150 and the display circuit board 141, and further improving the utilization efficiency of cold air.
Referring to fig. 3, it can be understood that the airflow of the air duct 133 reaches the upper end surface of the door 120 through the first through hole 143 after passing through the chamber 142, and the airflow flows outward along the upper end surface of the door 120 and flows along the surface of the door 120, so as to take away the heat of the upper end surface and the front side surface of the door 120 located in the projection area 122 of the handle 121, thereby achieving heat dissipation of the upper end portion of the door 120, effectively reducing the temperature rise of the door 120 located in the projection area 122 of the handle 121, and being more practical and reliable. The direction indicated by the arrow in fig. 3 is the direction of the airflow.
The handle 121 extends in the longitudinal direction of the door 120, and the projection area 122 of the handle 121 on the door 120 also extends in the longitudinal direction of the door 120.
