[0029] As can be seen from the above, the double-chamber baking control device provided by the embodiments of the present invention includes a first control unit. The first control unit includes a first control knob assembly for controlling the first baking chamber and a first display screen for displaying the baking state of the first baking chamber. A second control unit, the second control unit includes a second control knob assembly for controlling the second baking chamber and a second display screen for displaying the baking state of the second baking chamber.

The second baking chamber is controlled by the second control knob assembly, and the baking state of the second baking chamber is displayed by the second display screen.

Moreover, the baking states of the first baking chamber and the second baking chamber are respectively displayed by the first display screen and the second display screen, which is convenient for the user to intuitively understand the baking progress of the two baking chambers, avoiding the defect that it is not conducive to the user's observation to use one display screen to display the states of the two baking chambers, and the simultaneous start button is used to control the simultaneous start of the first baking chamber and the second baking chamber. Only one button is required to start the two baking chambers, realizing convenient control of the two baking chambers, and further ensuring the normal baking of the double-chamber oven.

[0030] The innovation points of the embodiments of the present invention include:

[0031] 1. The first baking chamber is controlled by the first control knob assembly, and the baking status of the first baking chamber is displayed on the first display screen. The second baking chamber is controlled by the second control knob assembly, and the baking status of the second baking chamber is displayed on the second display screen. Since the first control knob assembly and the second control knob assembly are mechanical components rather than electronic touch buttons, it is not easy to make operation mistakes. Therefore, reliable control of the two baking chambers can be achieved. Moreover, the baking statuses of the first baking chamber and the second baking chamber are respectively displayed by the first display screen and the second display screen, which is convenient for users to intuitively understand the baking progress of the two baking chambers, avoiding the defect that it is not conducive to user observation when using one display screen to display the status of the two baking chambers. In addition, by pressing the simultaneous start button, the first baking chamber and the second baking chamber can be started simultaneously. Only one button is required to start the two baking chambers, realizing convenient control of the two baking chambers, and thus ensuring the normal baking of the double-chamber oven.

[0032] 2. The first control knob assembly, the first display screen, the simultaneous start button, the second display screen, and the second control knob assembly are arranged in sequence, either horizontally or vertically. This sequential arrangement can make the layout of the above components more compact, which is conducive to installation on the oven, especially on the oven door body. It is necessary to reserve a window for users to observe the baking chamber inside, and this window occupies a relatively large space. Thus, adopting the above layout setting is conducive to their compatibility on the oven door body. Moreover, the simultaneous start button is set in the middle, which is convenient for users to identify that this button is used to start the two baking chambers simultaneously, not easy to make mistakes, and is also convenient for operation.

[0033] 3. By connecting the first adjustment knob to the first encoder and installing the first encoder on the circuit board, when the first adjustment knob is rotated, it drives the first encoder to rotate. The first encoder rotates and sends an adjustment signal to the circuit board to achieve the corresponding adjustment function.

[0034] 4. By installing both first buttons on the first button guide, and installing the first button guide and the two first push-type triggers on the circuit board, when any one of the first buttons is pressed, the first button presses the corresponding first push-type trigger, and the first push-type trigger realizes the corresponding start function through the circuit board.

[0035] 5. One first control knob assembly can achieve both the adjustment function and the start function, reducing costs. Moreover, by designing two buttons in one control knob and integrating the buttons in space, the overall structure is compact, which is conducive to the installation of the double-chamber baking control device on the oven door body.

[0036] 6. By setting the second push-type trigger to be installed on the circuit board, pressing the button starts the key simultaneously, and the start key controls the simultaneous start of the first baking chamber and the second baking chamber by pressing the second push-type trigger.

[0037] 7. By sleeving the first knob ring on the outer periphery of the first adjustment knob and fixedly connecting it to the first adjustment knob, the user can rotate the first adjustment knob through the first knob ring, greatly improving the convenience of rotation.

[0038] 8. Installing a dual-chamber baking control device on the oven door body can avoid occupying the baking space by installing the dual-chamber baking control device on the cabinet body, and can cooperate with the oven to provide a larger effective baking space. Also, to improve the user's observation effect of the baking state of the oven, a perspective window assembly is designed to perspective the baking states of the first baking chamber and the second baking chamber displayed on the first display screen and the second display screen, enhancing the user experience.

[0039] 9. By designing an integral perspective window mounting plate and detachably connecting it to the front shell, it is convenient for assembly during production. Also, a first perspective window and a second perspective window for displaying the first display screen and the second display screen are respectively designed on the perspective window mounting plate, and the contents of the two display screens are displayed by using the two perspective windows, which is beneficial for the user to visually distinguish the display contents of the two display screens when observing, enhancing the user experience.

[0040] 10. By setting a simultaneous start key mounting hole between the first perspective window and the second perspective window, the start key mounting hole is used to separate the first perspective window and the second perspective window, strengthening the separation effect of the two perspective windows visually, and being more conducive for the user to distinguish the display contents of the two perspective windows when observing. Also, the first control knob assembly mounting hole and the second control knob assembly mounting hole are also set on the perspective window mounting plate, realizing the installation of the first control knob assembly, the second control knob assembly and the simultaneous start key only by opening holes on the perspective window mounting plate, without other components, which is convenient for processing and reduces costs.

[0041] 11. By installing an air guiding device at the bottom of the perspective window bracket, setting an air inlet at the position on the bottom wall close to the simultaneous start button, setting a first air outlet at the position on the bottom wall close to the first control knob assembly, and setting a second air outlet at the position on the bottom wall close to the second control knob assembly, the air guiding device introduces external cold air into the installation cavity through the middle air inlet. The cold air is blown from the middle to both left and right sides under the drive of the air guiding device. The cold air blown from the middle to the left passes through the simultaneous start button and the first control unit respectively, which helps to keep the start button and the first control unit at a low temperature. Then, the cold air passing through the simultaneous start button and the first control unit becomes hot air and is discharged from the first air outlet. And the cold air blown from the middle to the right passes through the simultaneous start button and the second control unit, which helps to keep the simultaneous start button and the second control unit at a low temperature. Then, the cold air passing through the simultaneous start button and the second control unit becomes hot air and is discharged from the second air outlet. Thus, the external cold air is introduced by the air guiding device to dissipate heat and cool the double-chamber baking control device of the oven door, avoiding baking control failures caused by high temperature and improving the reliability of double-chamber control.

[0042] 12. By installing the circuit board heat insulation plate on the back of the circuit board with a gap between them, the circuit board heat insulation plate can isolate the heat transferred from the rear shell and avoid overheating of the circuit board.

[0043] Of course, it is not necessary for any product or method implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The embodiments of the present utility model disclose a double - cavity baking control device, an oven door body, and a double - cavity oven, which can solve the problem of conveniently and reliably controlling the two baking cavities of the double - cavity oven, and further ensure the normal baking of the double - cavity oven. The following is a detailed description of the embodiments of the present utility model.

[0054] <Embodiment 1>

[0055] This embodiment provides a double - cavity baking control device.

[0056] Figure 1 This is a schematic cross-sectional structure diagram of a dual-chamber baking control device provided by an embodiment of the present utility model. Refer to Figure 1 , the dual-chamber baking control device provided by the embodiment of the present utility model includes a first control unit, a second control unit, and a simultaneous start button 5.

[0057] Among them, the first control unit includes a first control knob assembly 1 for controlling the first baking chamber, and a first display screen 2 for displaying the baking state of the first baking chamber. In this embodiment, the control of the first baking chamber by the first control knob assembly 1 can at least include the control of baking temperature and baking time and the start of the first baking chamber. The first display screen 2 can at least display the baking temperature and baking time of the first baking chamber. Specifically, the first display screen 2 can be an electronic display screen. Of course, the first display screen 2 can also be selected from other types of display screens, such as a liquid crystal display screen, etc.

[0058] The second control unit includes a second control knob assembly 3 for controlling the second baking chamber, and a second display screen 4 for displaying the baking state of the second baking chamber. In this embodiment, the control of the second baking chamber by the second control knob assembly 3 can at least include the control of baking temperature and baking time and the start of the second baking chamber. The second display screen 4 can at least display the baking temperature and baking time of the second baking chamber. Specifically, the second display screen 4 can be an electronic display screen. Of course, the second display screen 4 can also be selected from other types of display screens, such as a liquid crystal display screen, etc. Specifically, the first display screen 2 and the second display screen 4 are of the same type, which is convenient for installation.

[0059] The simultaneous start button 5 is used to control the simultaneous start of the first baking chamber and the second baking chamber.

[0060] The working principle of the dual-chamber baking control device provided by this embodiment is: the first baking chamber is controlled by the first control knob assembly 1, and the baking state of the first baking chamber is displayed by the first display screen 2. The second baking chamber is controlled by the second control knob assembly 3, and the baking state of the second baking chamber is displayed by the second display screen 4. The simultaneous start button 5 is used to control the simultaneous start of the first baking chamber and the second baking chamber.

[0061] In summary, the dual-chamber baking control device provided by the embodiment of the present utility model includes a first control unit. The first control unit includes a first control knob assembly 1 for controlling the first baking chamber, and a first display screen 2 for displaying the baking state of the first baking chamber; a second control unit. The second control unit includes a second control knob assembly 3 for controlling the second baking chamber, and a second display screen 4 for displaying the baking state of the second baking chamber; a simultaneous start button 5. The simultaneous start button 5 is used to control the simultaneous start of the first baking chamber and the second baking chamber. Thus, the first baking chamber is controlled by the first control knob assembly 1, and the baking state of the first baking chamber is displayed by the first display screen 2. The second baking chamber is controlled by the second control knob assembly 3, and the baking state of the second baking chamber is displayed by the second display screen 4. Since the first control knob assembly 1 and the second control knob assembly 3 are mechanical components rather than electronic touch buttons, it is not easy to have operation errors. Therefore, reliable control of the two baking chambers can be achieved. Moreover, the baking states of the first baking chamber and the second baking chamber are respectively displayed by the first display screen 2 and the second display screen 4, which is convenient for the user to intuitively understand the baking progress of the two baking chambers, avoiding the defect that it is not conducive for the user to observe when using one display screen to display the states of the two baking chambers. And the first baking chamber and the second baking chamber are controlled to start simultaneously through the simultaneous start button 5. Only one button can complete the start of the two baking chambers, realizing convenient control of the two baking chambers, and further ensuring the normal baking of the dual-chamber oven.

[0062] Continue to refer to Figure 1 , the first display screen 2 and the second display screen 4 are respectively arranged on both sides of the simultaneous start button 5. For example, the first display screen 2 and the second display screen 4 are respectively arranged on the left and right sides of the simultaneous start button 5. The first control knob assembly 1 is arranged on the left side of the first display screen 2, and the second control knob assembly 3 is arranged on the right side of the second display screen 4. That is, the first control knob assembly 1, the first display screen 2, the simultaneous start button 5, the second display screen 4, and the second control knob assembly 3 are arranged in a horizontal layout. In other implementation manners, a vertical layout manner can also be adopted, that is, the first display screen 2 and the second display screen 4 are respectively arranged on the upper and lower sides of the simultaneous start button 5. The first control knob assembly 1 is arranged on the upper side of the first display screen 2, and the second control knob assembly 3 is arranged on the lower side of the second display screen 4. In this embodiment, the direction facing the user is the front, that is, the direction where the oven door body is located in the dual-chamber oven is the front, the direction where the user's left hand is located is the left, and the direction where the user's right hand is located is the right.

[0063] That is to say, the components are arranged in sequence, either horizontally or vertically. This sequential arrangement can make the layout of the above components more compact, which is conducive to installation on the oven. Especially on the oven door body, a window 90 is required to facilitate users to observe the baking cavity, and this window 90 occupies a relatively large space. Thus, arranging the dual-cavity baking control device of this embodiment in the above layout is conducive to the compatibility of the two on the oven door body. Moreover, setting the simultaneous start button 5 in the middle makes it convenient for users to identify that this button is used to simultaneously start the two baking cavities, which is not easy to make mistakes and is convenient for operation.

[0064] Continue to refer to Figure 1 , the dual-cavity baking control device provided by the embodiment of the present invention further includes a circuit board 6, a first encoder 7, and two first push-button triggers 8.

[0065] Figure 2 is an exploded structural schematic diagram of the first control knob assembly provided by the embodiment of the present invention. Refer to Figure 2 , the first control knob assembly 1 sequentially includes a first adjustment knob 11, a first button guide 12, and two first buttons 13 from back to front.

[0066] The first encoder 7 and the two first push-button triggers 8 are both installed on the circuit board 6. Specifically, the installation method on the circuit board 6 can be screw installation. Of course, other common connection methods such as welding and pin connection can also be used. The first push-button trigger 8 is used to receive the pressing operation of the first button 13 and send a signal to the circuit board 6.

[0067] The first adjustment knob 11 is connected to the first encoder 7. Specifically, the connection method between the two can be snap-fit connection. Of course, other common connection methods such as welding and pin connection can also be used. And the first adjustment knob 11 can be rotated to multiple first adjustment positions. When the first adjustment knob 11 is rotated to a certain first adjustment position, the first encoder 7 realizes the corresponding adjustment function through the circuit board 6. In this embodiment, the first adjustment knob 11 can be rotated to drive the first encoder 7 to rotate. When the first adjustment knob 11 rotates by different angles, it corresponds to different first adjustment positions. The specific corresponding relationship between the rotation angle and the first adjustment position can be set according to needs, and this embodiment does not make any restrictions. The first encoder 7 rotates to send an adjustment signal to the circuit board 6 to realize the corresponding adjustment function. Specifically, this adjustment function can be to adjust the baking mode of the first baking cavity, or to adjust the baking time, temperature, etc. of the first baking cavity.

[0068] Continue to refer to Figure 2 , the first button guide 12 is installed on the circuit board 6. Specifically, the connection method between the two can be snap-fit connection. Of course, other common connection methods such as welding and pin connection can also be used.

[0069] The two first buttons 13 are both installed on the first button guide 12. Specifically, each first button 13 is connected to the first button guide 12 through a first elastic return structure. The first elastic return structure may include a button buckle 131 provided at the lower end of the first button 13, a first return spring installed between the first button 13 and the first button guide 12, and a chute provided on the first button guide 12. A positioning hole is provided at each of the upper and lower ends of the chute. When the first button 13 is in the unpressed state, the return spring is in a relaxed state, and the button buckle 131 is located in the positioning hole at the upper end of the chute. When the first button 13 is pressed, the first return spring is compressed, and the button buckle 131 moves along the chute and falls into the positioning hole at the lower end. Of course, the first elastic return structure can also be other common types of elastic return structures, and this embodiment does not make any limitation on this.

[0070] The two first buttons 13 correspond to two first push-button triggers 8 installed on the circuit board 6. That is, when a certain first button 13 is in the pressed state, it presses its corresponding first push-button trigger 8, and the first push-button trigger 8 realizes the corresponding start function through the circuit board 6. Among them, the start function can be to start the first baking chamber, start the temperature mode, and / or start the time mode.

[0071] Specifically, each first button 13 is provided with a first pressing column 132. When the first button 13 is in the pressed state, the corresponding first push-button trigger 8 is pressed through the first pressing column 132. In this embodiment, the first button guide 12 plays a role in guiding the two first buttons 13 to ensure that the two first buttons 13 can be pressed downward. The two first buttons 13 can be arranged left and right or up and down.

[0072] In this embodiment, the working principle of the first operation knob assembly 1 is as follows: Press any one of the first buttons 13, and this first button 13 presses its corresponding first push-button trigger 8. The first push-button trigger 8 realizes the corresponding start function through the circuit board 6; rotate the first adjustment knob 11, drive the first encoder 7 to rotate, and the first encoder 7 rotates to send an adjustment signal to the circuit board 6 to thereby realize the corresponding adjustment function.

[0073] Thus, by connecting the first adjustment knob 11 with the first encoder 7 and installing the first encoder 7 on the circuit board 6, rotating the first adjustment knob 11 drives the first encoder 7 to rotate, and the first encoder 7 rotates to send an adjustment signal to the circuit board 6 to thereby realize the corresponding adjustment function.

[0074] Moreover, by installing both of the two first buttons 13 on the first button guide 12, and installing the first button guide 12 and the two first push-type triggers 8 on the circuit board 6, when any one of the first buttons 13 is pressed, the first button 13 presses the corresponding first push-type trigger 8, and the first push-type trigger 8 realizes the corresponding start function through the circuit board 6.

[0075] Moreover, by using one first control knob assembly 1, both the adjustment function and the start function can be realized, reducing the cost. And, by designing two buttons in one control knob and integrating the buttons in terms of space, the overall structure is compact, which is beneficial to the installation of the dual-chamber baking control device of this embodiment on the oven door body.

[0076] Continue to refer to Figure 2 The first control knob assembly 1 further includes a first knob ring 14. The first knob ring is sleeved on the outer periphery of the first adjustment knob 11 and fixedly connected to the first adjustment knob 11. Specifically, the way of their fixed connection can be screw connection, or other common connection ways such as welding and pin connection.

[0077] Thus, by sleeving the first knob ring 14 on the outer periphery of the first adjustment knob 11 and fixedly connecting it to the first adjustment knob 11, the user can rotate the first adjustment knob 11 through the first knob ring 14, greatly improving the convenience of rotation.

[0078] Continue to refer to Figure 1 The dual-chamber baking control device provided by the embodiment of the present invention further includes a second push-type trigger 9.

[0079] The second push-type trigger 9 is installed on the circuit board 6. Specifically, the way of installing it on the circuit board 6 can be screw installation. Of course, other common connection ways such as welding and pin connection are also possible.

[0080] When the simultaneous start button 5 is in the pressed state, it presses the second push-type trigger 9 to control the simultaneous start of the first baking chamber and the second baking chamber. Among them, the simultaneous start button 5 is provided with a second pressing column, and the second return spring is arranged between the simultaneous start button 5 and the circuit board 6. When the simultaneous start button 5 is pressed, the second return spring is compressed, and the second pressing column presses the second push-type trigger 9 to control the simultaneous start of the first baking chamber and the second baking chamber, and then the second return spring returns to its original state.

[0081] Thus, by setting the second push-type trigger 9 to be installed on the circuit board 6, when the simultaneous start button 5 is pressed, the simultaneous start button 5 presses the second push-type trigger 9 to control the simultaneous start of the first baking chamber and the second baking chamber.

[0082] Continue to refer to Figure 3, at the same time, a decorative piece 51 is pasted on the front surface of the start button 5, which is beautiful and good-looking.

[0083] Continue to refer to Figures 1-3 , the dual-chamber baking control device provided by the embodiment of the present utility model further includes a second encoder 10 and two third push-type triggers 80. The second control knob assembly 3 sequentially includes a second adjustment knob 31, a second button guide 32, and two second buttons 33 from back to front. The second encoder 10 and the two third push-type triggers 80 are both installed on the circuit board 6. The installation method and working principle of the second control knob assembly 3 are the same as those of the first control knob assembly 1. For specific reference, see the relevant introduction of the first control knob assembly 1, which will not be elaborated here.

[0084] Continue to refer to Figure 2 , the second control knob assembly 3 further includes a second knob ring 34.

See Figure 3 , the oven door body provided by the embodiment of the present utility model includes a front shell 20, a rear shell 30, and a perspective window assembly. In this embodiment, the direction facing the user is the front, that is, the direction where the front shell 20 is located is the front. Correspondingly, the direction away from the user is the rear, that is, the direction where the rear shell 30 is located is the rear.

[0088] An installation cavity is formed between the front shell 20 and the rear shell 30. The dual-chamber baking control device provided in the above-mentioned Embodiment I is provided in the installation cavity. The perspective window assembly is installed on the front shell 20 and is used to see through the first display screen 2 and the second display screen 4. In this embodiment, the dual-chamber baking control device is arranged below the installation cavity, that is, below the door and window 90 of the oven door body. Correspondingly, the perspective window assembly is also located below the door and window 90. Of course, in other embodiments, the dual-chamber baking control device can also be installed above the door and window 90, or on the left or right side of the door and window 90.

[0089] It can be seen that for the oven door body provided in this embodiment, by installing the double-chamber baking control device thereon, it is possible to avoid occupying the baking space due to the installation of the double-chamber baking control device on the cabinet body, and it can cooperate with the oven to provide a larger effective baking space. Moreover, in order to improve the user's observation effect of the baking state of the oven, a perspective window assembly is designed to perspective the baking states of the first baking chamber and the second baking chamber displayed on the first display screen 2 and the second display screen 4, thereby enhancing the user experience. In addition, the functional effects of the oven door body in this embodiment due to having the double-chamber baking control device of Embodiment 1 will not be elaborated here.

[0090] Continue to refer to Figure 3 , the perspective window assembly may include a perspective window mounting plate 40. The perspective window mounting plate 40 is provided with a first perspective window 401 and a second perspective window 402. Specifically, the first perspective window 401 and the second perspective window 402 are integrally injection-molded with the perspective window mounting plate 40. Of course, other common methods that can integrally form the three can also be used.

[0091] Continue to refer to Figure 3 , the front surface of the first display screen 2 is close to the back surface of the first perspective window 401, and the front surface of the second display screen 4 is close to the back surface of the second perspective window 402, so that the display contents of the first display screen 2 and the second display screen 4 can be respectively displayed through the first perspective window 401 and the second perspective window 402. The distance between the two is not specifically limited here. In the extreme case, the front surface of the first display screen 2 is closely attached to the back surface of the first perspective window 401, and the front surface of the second display screen 4 is closely attached to the back surface of the second perspective window 402. Among them, the back surface of the first perspective window 401 refers to the side away from the front shell 20.

[0092] Continue to refer to Figure 3 , the front shell 20 is provided with a first through hole 201 for accommodating the perspective window mounting plate 40, and the front shell 20 is detachably connected to the perspective window mounting plate 40. Specifically, buckle mounting holes 403 are provided along the outer periphery of the first perspective window 401 and the second perspective window 402, and the front shell 20 is provided with front shell buckles 404 corresponding to the buckle mounting holes 403. The perspective window mounting plate 40 is connected to the front shell 20 by the cooperation of the front shell buckles 404 and the buckle mounting holes 403, so that the first perspective window 401 and the second perspective window 402 are located in the first through hole 201. Specifically, both the first perspective window 401 and the second perspective window 402 are clamped with the first through hole 201.

[0093] Among them, the arrangement and quantity of the front shell buckles 404 and the buckle mounting holes 403 can be adjusted according to needs and are not specifically limited here.

[0094] Thus, by designing an integral perspective window mounting plate 40 and detachably connecting it to the front shell 20, it is convenient for assembly during production. Moreover, a first perspective window 401 and a second perspective window 402 are respectively designed on the perspective window mounting plate 40 for displaying the first display screen 2 and the second display screen 4. The contents of the two display screens are displayed by using the two perspective windows, which is conducive to visually distinguishing the display contents of the two display screens for the user during observation and improving the user experience.

[0095] Continue to refer to Figure 3 , a simultaneous start button mounting hole 405 is provided between the first perspective window 401 and the second perspective window 402. A first control knob assembly mounting hole 4011 and a second control knob assembly mounting hole 4021 are respectively provided on one side of the first perspective window 401 and the second perspective window 402 away from the simultaneous start button mounting hole 405. Figure 3 In the given example, the first control knob assembly mounting hole 4011 is provided on the left side of the first display screen 2 of the first perspective window 401, and the second control knob assembly mounting hole 4021 is provided on the right side of the second display screen 4 of the second perspective window 402. Of course, in other embodiments, the positions of the first control knob assembly mounting hole 4011 and the second control knob assembly mounting hole 4021 can be adaptively adjusted according to the positions of the first control knob assembly 1 and the second control knob assembly 3.

[0096] Specifically, the first control knob assembly 1 is installed in the first control knob assembly mounting hole 4011, and part of the first control knob assembly 1 is located outside the first through hole. Specifically, the first control knob assembly 1 is in clearance fit with the first control knob assembly mounting hole 4011 to facilitate the user to rotate the first control knob assembly 1.

[0097] Similarly, the second control knob assembly 3 is installed in the second control knob assembly mounting hole 4021, and part of the second control knob assembly 3 is located outside the first through hole. The second control knob assembly 3 is in clearance fit with the second control knob assembly mounting hole 4021.

[0098] Continue to refer to Figure 3 , the simultaneous start button 5 is installed in the simultaneous start button mounting hole 405. Specifically, the simultaneous start button 5 is in clamping or interference fit with the simultaneous start button mounting hole 405.

[0099] Thus, by providing a simultaneous start button mounting hole 405 between the first perspective window 401 and the second perspective window 402, the start button mounting hole 405 is used to separate the first perspective window 401 and the second perspective window 402, enhancing the visual separation effect between the two perspective windows and making it easier for users to distinguish the display contents of the two perspective windows during observation. In addition, the first control knob assembly mounting hole 4011 and the second control knob assembly mounting hole 4021 are also provided on the perspective window mounting plate 40, enabling the installation of the first control knob assembly 1, the second control knob assembly 3, and the simultaneous start button 5 by only opening holes on the perspective window mounting plate 40 without the need for other components, which is convenient for processing and reduces costs.

[0100] Figure 4 A schematic structural diagram of an oven door body provided by an embodiment of the present invention at an angle is shown in Figure 3 and Figure 4 , the perspective window assembly further includes a perspective window bracket 50, and the perspective window bracket 50 is clamped between the front shell 20 and the perspective window mounting plate 40. Specifically, the perspective window mounting plate 40 is connected to the front shell 20 through the cooperation of the front shell buckle 404 and the buckle mounting hole 403, thereby clamping the perspective window bracket 50 between the front shell 20 and the perspective window mounting plate 40.

[0101] Continuing to refer to Figure 4 , an air guiding device 60 is installed at the bottom of the perspective window bracket 50. Specifically, the installation method can be screw connection, and of course, other common connection methods such as welding and pin connection can also be used. The air guiding device 60 can be a DC fan. Of course, the air guiding device 60 can also be other types of fans or motors, etc.

[0102] An air inlet 2021 is provided at the bottom wall 202 of the front shell 20 near the position of the simultaneous start button 5, a first air outlet 2022 is provided at the bottom wall 202 of the front shell 20 near the position of the first control knob assembly 1, and a second air outlet 2023 is provided at the bottom wall 202 of the front shell 20 near the position of the second control knob assembly 3. Among them, the air inlet 2021 can include a plurality of elongated through holes arranged in an array. It should also be known that the arrangement and shape of the air inlet 2021, as well as the shapes of the first air outlet 2022 and the second air outlet 2023, can be adjusted according to needs and are not specifically limited herein.

[0103] The cold air introduced by the air guiding device 60 enters the installation cavity from the air inlet 2021, and under the drive of the air guiding device 60, the cold air blows from the middle to the left and is discharged from the first air outlet 2022 through the simultaneous start button 5 and the first control unit, and blows from the middle to the right and is discharged from the second air outlet 2023 through the simultaneous start button 5 and the second control unit.

[0104] The working principle of heat dissipation through the air guiding device 60 in this embodiment is as follows: The air guiding device 60 introduces external cold air into the installation cavity through the middle air inlet 2021. Driven by the air guiding device 6, the cold air blows from the middle to both left and right sides. The cold air blowing from the middle to the left passes through the simultaneous start button 5 and the first control unit, which helps to keep the start button 5 and the first control unit at a low temperature. Then, the cold air passing through the simultaneous start button 5 and the first control unit becomes hot air and is discharged from the first air outlet 2022. And the cold air blowing from the middle to the right passes through the simultaneous start button 5 and the second control unit, which helps to keep the simultaneous start button 5 and the second control unit at a low temperature. Then, the cold air passing through the simultaneous start button 5 and the second control unit becomes hot air and is discharged from the second air outlet 2023. Thus, by introducing external cold air using the air guiding device 60, the dual-chamber baking control device of the oven door body is cooled by heat dissipation, avoiding baking control failures caused by high temperatures and improving the reliability of dual-chamber control.

[0105] Continue to refer to Figure 3 and 4 The dual-chamber baking control device further includes a circuit board heat insulation plate 70. The circuit board heat insulation plate 70 is installed on the back of the circuit board 6, and there is a gap between the two. Specifically, the installation method can be stud connection. Of course, it can also be other common connection methods that can make there be a gap between the two.

[0106] Thus, by installing the circuit board heat insulation plate 70 on the back of the circuit board 6 and having a gap between the two, the circuit board heat insulation plate 70 can isolate the heat transferred from the rear case 30 and prevent the circuit board 6 from overheating.
