[0028] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a guide structure, including a box body 10 and a door body, the box body 10 is provided with a baking cavity 11, the door body is hinged to the box body 10 and can close the baking cavity 11; the inner bottom wall of the baking cavity 11 corresponding to the door body is provided with a hot air blower 12, the inner side wall of the baking cavity 11 is provided with a guide assembly 20, the guide assembly 20 includes a guide plate 21 and a driving member 22, the driving member 22 is fixed to the box body 10 and can drive the guide plate 21 to move, so as to change the projection area of the guide plate 21 on the inner bottom wall of the baking cavity 11.
[0029] By arranging a movable guide plate 21 in the baking chamber 11 and changing the projection area of the guide plate 21 on the bottom wall of the baking chamber 11 through the driving member 22, the guide plate 21 can guide and change the hot air path. On the one hand, it can reduce the amount of hot air directly blown by the hot air blower 12 to the door glass, avoid excessive and too fast contact between the hot air and the door glass, and prevent the door temperature from rising too high. On the other hand, the hot air can flow in the baking chamber 11 under the guidance of the guide plate 21 to improve the baking thermal efficiency inside the baking chamber 11.
[0030] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the guide plate 21 is hinged to the inner wall of the baking chamber 11, and the driving member 22 can drive the guide plate 21 to rotate.
[0031] Of course, in some other embodiments, the projection area of the guide plate 21 on the bottom wall of the baking chamber 11 can also be changed by driving the guide plate 21 to translate, extend or deform by the driving member 22. As long as the amount of hot air directly blown by the hot air blower 12 to the door glass can be changed to avoid excessive and too fast contact between the hot air and the door glass, thereby preventing the door temperature from rising too high, the present application will not make any further limitations here.
[0032] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the guide plate 21 is in a long strip shape, the long side of the guide plate 21 is hinged to the inner wall of the baking cavity 11, and the long side is parallel to the inner bottom wall of the baking cavity 11.
[0033] Such a configuration can minimize the intrusion of the guide plate 21 into the internal space of the baking chamber 11 while ensuring that the guide plate 21 has a relatively large hot air blocking area, so as to prevent the guide plate 21 from interfering with the baking tray or other structures inside the baking chamber 11.
[0034] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the guide plate 21 includes a curved surface segment 21a, which bends toward the direction close to the hot air blower 12; the curved surface segment 21a is used to guide the hot air and change the hot air path, so that the hot air no longer blows directly onto the door glass, but circulates in the baking cavity 11, thereby reducing the heat exchange between the hot air and the door glass and increasing the heat exchange between the hot air and the food in the baking cavity 11, thereby preventing the door glass from overheating and improving the baking thermal efficiency inside the baking cavity 11.
[0035] For details, please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the guide plate 21 includes a plane segment 21b and a curved segment 21a, the plane segment 21b is hinged to the inner wall of the baking chamber 11, and the curved segment 21a is fixed to one end of the plane segment 21b away from the inner wall of the baking chamber 11.
[0036] Please refer to Figure 3 As shown, in some embodiments, a receiving groove 11 a is formed on the inner wall of the baking cavity 11 , and the guide plate 21 can be rotated to be completely received in the receiving groove 11 a .
[0037] When the door is opened, the guide plate 21 is driven by the driving member 22 to rotate until it is completely accommodated in the accommodating groove 11 a, so as to prevent the guide plate 21 from affecting the user's normal taking of food in the baking cavity 11 .
[0038] Specifically, the opening and closing of the guide plate 21 can be controlled according to whether the door is open and whether the hot air blower 12 is working. When the door is open or the hot air blower 12 is not working, the guide plate 21 is retracted and closed without affecting the user's normal taking operation; when the hot air blower 12 is working, the guide plate 21 is opened to reduce the heat exchange between the hot air and the door glass, thereby avoiding excessive temperature rise of the door glass.
[0039] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the driving member 22 is a telescopic motor fixed to the box body 10, the motor body 22a of the telescopic motor is arranged outside the box body 10, the telescopic rod 22b of the telescopic motor passes through the box body 10 to the baking chamber 11, and the telescopic rod 22b is against the side surface of the guide plate 21 facing away from the hot air blower 12.
[0040] The telescopic motor drives the telescopic rod 22b to extend so as to push out and open the guide plate 21. Conversely, when the telescopic rod 22b is retracted, the guide plate 21 can be retracted and closed under the action of the hot wind.
[0041] Of course, in some other embodiments, the telescopic rod 22b may also be connected to the guide plate 21, so that the guide plate 21 can be opened or closed accordingly as the telescopic rod 22b is extended or retracted.
[0042] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, a group of flow guide components 20 are respectively disposed on two corresponding inner side walls of the baking chamber 11.
[0043] It is not difficult to understand that different numbers of guide components 20 can also be set at other positions in the baking cavity 11, as long as the projection area of the guide plate 21 on the bottom wall of the baking cavity 11 can be changed to prevent hot air from blowing directly onto the door glass.
[0044] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the guide assembly 20 is arranged on the inner wall of the baking chamber 11 close to the door body, so that the hot air contacts the guide plate 21 after passing through the food to be baked, thereby preventing the guide plate 21 from affecting normal baking.
[0045] A second aspect of the present application provides an oven, comprising the above-mentioned flow guide structure.
[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
