DETAILED DESCRIPTION

[0021] In the existing design of steam ovens, the display panel and the door are separately arranged, and an exhaust port is arranged between the display panel and the door. This, on the one hand, will result in a strong sense of segmentation in the appearance of the steam oven, affecting the overall aesthetics of the steam oven. On the other hand, due to the need to maximize the volume of the cavity, the door will be set relatively large, which will occupy the setting space of the display panel, resulting in a smaller display panel area, thereby affecting the interactive experience of the display panel.

[0022] In order to solve the problem that the appearance of the steam oven is highly segmented and the interactive experience of the display panel is poor, the prior art attempts to integrate the door body and the display panel. However, with such an arrangement, the temperature on the door body side is too high, which can easily cause the display panel and the internal control circuit board to overheat and fail.

[0023] In view of this, it is necessary to improve a steam oven to solve the problem in the prior art that the integrated steam oven door panel is overheated, causing the display panel and the control circuit board to fail easily.

[0024] See also Figure 1-Figure 3Specifically, the steam oven includes a main box body 100 and a door structure. The main box body 100 is provided with a steaming and baking cavity 110 , and a movable cover of the door structure is provided at the opening of the steaming and baking cavity 110 .

[0025] It should be noted that the steaming and baking cavity 110 has an exhaust port (not shown). During use, the exhaust port is arranged at the upper part of the steaming and baking oven, and the door structure is arranged at the lower part of the steaming and baking oven, that is, the working height of the exhaust port is greater than the working height of the door structure. In this way, it is also possible to prevent the exhaust port from heating the door structure, causing overheating and damage to the control circuit board 400 in the door structure.

[0026] It should be noted that the steam oven itself can be placed in many different ways, but during use, there is usually only one way of placement. Therefore, the "working height" means that based on the placement of the steam oven when in use, the vertical height of the exhaust port is greater than the vertical height of the door structure.

[0027] like Figure 1 and Figure 3 As shown, the door structure includes a main door 200, a display screen 300, a control circuit board 400 and a fan assembly, and the control circuit board 400 is electrically connected to the fan assembly and the display screen 300. The main door 200 is provided with a heat dissipation cavity 240 and an air inlet 250 and an air outlet 260 respectively connected to the heat dissipation cavity 240, and the control circuit board 400 and the fan assembly are respectively arranged in the heat dissipation cavity 240, wherein the air inlet 250 can be connected to the air outlet 260 through the fan assembly, so that the gas in the heat dissipation cavity 240 forms a circulating airflow. The display screen 300 is arranged on the outer wall surface of the heat dissipation cavity 240 away from the steaming and baking cavity 110.

[0028] In this arrangement, the fan assembly allows external air to enter the heat dissipation cavity 240 and take away the heat in the door structure, greatly reducing the temperature of the door structure and effectively avoiding the probability of overheating failure of the display screen 300 and the control circuit board 400. In addition, the display screen 300 in the present application is arranged on the outer wall surface of the heat dissipation cavity 240 away from the steaming and baking cavity 110, which not only greatly expands the coverage area of ​​the display screen 300, but also the integrated arrangement of the display screen 300 and the door structure makes the facade of the entire steaming and baking oven more beautiful.

[0029] Further, in one embodiment, if Figure 1 and Figure 3 As shown, the control circuit board 400 is installed on one side of the heat dissipation cavity 240 close to the air inlet 250 .

[0030] Obviously, the temperature of the airflow at the air inlet 250 is the lowest. Therefore, such a configuration can enable the control circuit board 400 to obtain a better heat dissipation effect.

[0031] In one embodiment, if Figure 1and Figure 3 As shown, the main door body 200 includes a heat-insulating side plate 210, a display mounting plate 220 and a sealing edge strip 230. The heat-insulating side plate 210 is disposed on a side of the heat dissipation cavity 240 close to the steaming and baking cavity 110 to isolate the heat of the steaming and baking cavity 110. The display mounting plate 220 is disposed on a side of the heat dissipation cavity 240 away from the steaming and baking cavity 110, and the display screen 300 is installed on a side of the display mounting plate 220 away from the heat dissipation cavity 240.

[0032] The heat-insulating side panels 210 and the display mounting panels 220 are spaced apart along the thickness direction of the door structure to form a mounting gap, and the sealing edge strips 230 are sealingly disposed on part or all of the circumference of the mounting gap to enclose the mounting gap to form a heat dissipation cavity 240 .

[0033] It should be noted that the thickness direction of the door structure refers to the direction perpendicular to the display mounting plate 220 (or the insulation side plate 210), the height direction of the door structure refers to the direction from the bottom of the steam oven to the top of the steam oven, and the width direction of the door structure refers to the direction from the left side of the steam oven to the right side of the steam oven.

[0034] Furthermore, it should be noted that the door structure can be provided not only in the steam oven but also in other electrical appliances, such as a toaster, etc., which are not listed here one by one.

[0035] Specifically, the heat insulating side plate 210, the display mounting plate 220 and the sealing edge strip 230 may be bonded, clamped or welded, etc., which are not listed here one by one.

[0036] Obviously, such a configuration, on the one hand, facilitates the assembly and disassembly of the main door body 200, and on the other hand, facilitates the installation and disassembly of the control circuit board 400 and the fan assembly.

[0037] However, it is not limited thereto. In other embodiments, the sealing edge strip 230 and the heat insulating side panel 210 may also be an integrally formed part, or the sealing edge strip 230 and the display mounting plate 220 may be an integrally formed part.

[0038] And, in another embodiment, the display screen 300 and the display mounting plate 220 are an integrally formed structure.

[0039] Further, in one embodiment, if Figure 1 and Figure 3As shown, the main door body 200 also includes a first partition bar 271 and a second partition bar 272 respectively extending along the height direction of the door body structure, the first partition bar 271 and the second partition bar 272 are respectively connected to the inner wall surface of the insulation side plate 210 (the wall surface close to the heat dissipation cavity 240) and the inner wall surface of the display mounting plate 220 (the wall surface close to the heat dissipation cavity 240), the first partition bar 271 and the second partition bar 272 are spaced apart along the width direction of the door body structure to separate the heat dissipation cavity 240 into a first air inlet channel 241, an air outlet channel 243 and a second air inlet channel 242 arranged in sequence along the width direction of the door body structure.

[0040] The first air inlet channel 241 is connected to the air outlet channel 243 to form a first heat dissipation channel, and the second air inlet channel 242 is connected to the air outlet channel 243 to form a second heat dissipation channel.

[0041] Such an arrangement enables the door structure to form two semi-independent first heat dissipation channels and second heat dissipation channels along its width direction, and the reason why they are semi-independent is that the air outlet channels 243 of the two are shared. Such an arrangement can significantly extend the total length of the airflow channel in the heat dissipation cavity 240, increase the contact time between the external air and the inner wall of the heat dissipation cavity 240, and thus improve the heat dissipation effect of the door structure.

[0042] Of course, the first partition bar 271 and the second partition bar 272 may also extend in a curved shape, such as an S-shape, so that the total length of the air flow channel in the heat dissipation cavity 240 can be further extended.

[0043] Moreover, such an arrangement can make the heat dissipation of the door structure on both sides along the width direction more balanced, thereby avoiding the problem of thermal stress damage caused by uneven heat dissipation at both ends of the door structure.

[0044] Furthermore, the first spacer bar 271 and the second spacer bar 272 are provided to increase the support of the heat insulating side plate 210 to the display mounting plate 220 , thereby improving the installation strength of the display mounting plate 220 and the display screen 300 .

[0045] However, it is not limited thereto. In other embodiments, only one sealing strip (not shown) may be disposed in the middle of the heat dissipation cavity 240 to divide the heat dissipation cavity 240 into two, one side for air intake and the other side for air outlet.

[0046] Further, in one embodiment, if Figure 1 and Figure 3 As shown, the fan assembly includes a first fan 510 and a second fan 520. The upper end of the first partition bar 271 and the top end of the heat dissipation cavity 240 are spaced apart to form a first communication port. The first fan 510 is installed at the first communication port to connect the first air inlet channel 241 and the air outlet channel 243. In addition, the end of the first air inlet channel 241 away from the first fan 510 is the air inlet 250.

[0047] Correspondingly, the upper end of the second partition bar 272 and the top of the heat dissipation cavity 240 are spaced apart to form a second communication port, and the second fan 520 is installed at the second communication port to connect the second air inlet channel 242 and the air outlet channel 243. In addition, the end of the second air inlet channel 242 away from the second fan 520 is the air inlet 250.

[0048] In addition, one end of the air outlet channel 243 away from the first fan 510 and the second fan 520 is an air outlet 260 .

[0049] In this way, the first fan 510 is arranged in the first heat dissipation channel, and the second fan 520 is arranged in the second heat dissipation channel. On the one hand, the circulation rate of the air in the heat dissipation cavity 240 is improved, thereby improving the heat dissipation effect of the door structure. On the other hand, when one of the first fan 510 and the second fan 520 is damaged, the other can operate normally, thereby improving the operating fault tolerance of the fan assembly and reducing the probability of overheating and damage to the door structure.

[0050] But not limited to this, in other embodiments, the first partition bar 271 can also extend to the top of the heat dissipation cavity 240, and the first partition bar 271 is provided with a first through hole (not shown) connecting the first air inlet channel 241 and the air outlet channel 243, and the first fan 510 is installed at the first through hole.

[0051] Furthermore, the second partition bar 272 may also extend to the top of the heat dissipation cavity 240, and the second partition bar 272 is provided with a second through hole (not shown) connecting the second air inlet channel 242 and the air outlet channel 243, and the second fan 520 is installed at the second through hole.

[0052] Furthermore, in one embodiment, if Figure 1 and Figure 3 As shown, the sealing edge strip 230 arranged on the side of the heat dissipation cavity 240 close to the exhaust port is defined as the top edge strip 231, the fan assembly is arranged at one end of the heat dissipation cavity 240 close to the top edge strip 231, and the top edge strip 231 is provided with a third air inlet channel 232 connected to the air outlet channel 243. Obviously, the end of the third air inlet channel 232 away from the heat dissipation cavity 240 is the air inlet 250.

[0053] The control circuit board 400 is disposed at one end of the heat dissipation cavity 240 close to the third air inlet channel 232 , and the control circuit board 400 is disposed between the first fan 510 and the second fan 520 .

[0054] Specifically, the top side strip 231 is provided with a plurality of communication holes (not shown), and the plurality of communication holes form the third air inlet channel 232 .

[0055] Such an arrangement further improves the heat dissipation efficiency of the heat dissipation cavity 240 .
