[0033] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0034] Reference below Figure 1-Figure 7 The cooking device 100 according to an embodiment of the present application is described. The cooking device 100 can be used to cook food.

[0035] The cooking device 100 according to an embodiment of the present application includes: a cooking body 1 and an oven door 2 .

[0036] Among them, the cooking body 1 forms a cavity open to one side, the oven door 2 is arranged on the cooking body 1, and the oven door 2 is located at the open end of the cavity. The oven door 2 cooperates with the cavity to define a cooking cavity, which is used to place ingredients, and the ingredients can be cooked in the cooking cavity.

[0037] Combine Figure 2 and Figure 6 As shown, the oven door 2 includes an oven door body 21 and a ventilation assembly 22. The oven door body 21 is provided with a first ventilation portion 211 and a second ventilation portion 212 that connect the cooking cavity and the outside of the oven door body 21. The ventilation assembly 22 is disposed on the oven door body 21 and can selectively open or close the first ventilation portion 211 and the second ventilation portion 212. The ventilation assembly 22 can also exhaust gas from the cooking cavity through one of the first ventilation portion 211 and the second ventilation portion 212 to meet the exhaust requirements of the cooking cavity.

[0038] Among them, the cooking cavity can be connected to the outside through the first ventilation part 211 and the second ventilation part 212 on the oven door body 21, so that the steam in the cooking cavity can be discharged from the cooking cavity to the outside. During the steam discharge process, the water vapor in the cooking cavity can be brought out, thereby realizing the dehumidification function of the cooking device 100, and then improving the cooking effect of the cooking device 100 on the food.

[0039] It can be understood that when the first ventilation part 211 and the second ventilation part 212 are respectively connected to the cooking cavity and the outside of the cooking device 100, the gas in the cooking cavity can be discharged outward through the first ventilation part 211 to remove moisture and water in the cooking cavity. In the process of the gas being discharged outward through the first ventilation part 211, the air outside the cooking device 100 can enter the cooking cavity through the second ventilation part 212 to ensure that the pressure in the cooking cavity is in a balanced state, and the oxygen content in the cooking cavity can be increased, so that gas circulation in the cooking cavity can be realized, and the cooking effect of the cooking device 100 on the food can be improved.

[0040] It should be noted that currently, cooking devices (such as steam ovens and microwave ovens) can steam and bake food. In related technologies, during the steaming process, cooking devices typically seal the cooking cavity to prevent steam leakage. This prevents moisture from quickly draining from the food during cooking, affecting the dehydration of the food and resulting in poor cooking performance.

[0041] Among them, taking the existing cooking equipment for steaming pasta (such as steamed buns, etc.) as an example, during the cooking process, the dough needs to be arranged in the cooking cavity, and the cooking cavity remains sealed during the steaming process, which results in the moisture in the dough cannot be quickly discharged, affecting the dehydration effect of the pasta, making the steamed pasta GI (i.e., glycemic index) higher (for example, the GI value can reach 87), which is not convenient for some people (such as patients with high blood sugar, diabetes, etc.) to eat.

[0042] In the present application, the first and second ventilation portions 211, 212 are opened via the ventilation assembly 22, allowing steam in the cooking cavity to be exhausted through one of the first and second ventilation portions 211, 212, and allowing air outside the cooking cavity to enter the cooking cavity through the other of the first and second ventilation portions 211, 212, thereby increasing the oxygen content in the cooking cavity. This allows the noodle dough to be dehydrated, thereby increasing the content of slowly digestible starch and resistant starch in the noodle, lowering the glycemic index of the food, and ultimately producing noodle food that meets the needs of patients with hypertension, diabetes, and the like.

[0043] Among them, the above-mentioned exhaust and dehumidification actions during the cooking process by the cooking device 100 can be set according to the cooking requirements of the ingredients, and the cooking control strategy of the cooking device 100 is not limited here.

[0044] It should be noted that the cooking device 100 in the present application can be configured as a steam oven or a microwave oven, and no specific limitation is made here. In other words, the cooking device 100 in the present application at least has the cooking functions of steaming and baking food, and can also add microwave cooking functions according to design requirements.

[0045] Furthermore, when the cooking device 100 in the present application has a baking function, the ventilation component 22 can be used to increase the oxygen content in the cooking device 100, which helps to enhance the aromatic substances (such as 2-decenal, etc.) produced by the food during the cooking process, thereby improving the cooking effect of the cooking device 100 on the food.

[0046] According to the cooking device 100 of the embodiment of the present application, compared with the cooking equipment in the prior art, the cooking cavity can be connected with the outside of the cooking device 100 during the cooking process, and the oxygen content in the cooking cavity can be increased while discharging moisture and water in the cooking cavity, thereby increasing the content of slowly digestible starch and resistant starch in steamed pasta, and also improving the crispness and coloring effect of baked ingredients.

[0047] It is understood that when the cooking device 100 is in the steaming cooking mode, the ventilation assembly 22 can be used to discharge moisture and water from the cooking cavity, thereby reducing the water content of the steamed noodle dough and helping to increase the content of slowly digestible and resistant starch in the noodle dough. When the device is in the baking cooking mode, the ventilation assembly 22 can be used to discharge moisture and water from the cooking cavity, thereby reducing the humidity in the cooking cavity and improving the crispness of the baked food. In addition, the ventilation assembly 22 can be used to replenish air into the cooking cavity to increase the oxygen content in the cooking cavity and enhance the aroma of the food. In other words, the cooking device 100 of the present application can control the operating state of the ventilation assembly 22 according to cooking needs to improve the steaming or baking cooking effect of the cooking device 100 on the food.

[0048] In some embodiments of the present application, the ventilation component 22 includes: an exhaust component 221 and an air supply component 222 .

[0049] Among them, the exhaust component 221 is arranged at the first ventilation part 211, and the exhaust component 221 can discharge the gas in the cooking cavity to the outside of the oven door body 21; the air supply component 222 is arranged at the second ventilation part 212, and the air supply component 222 can transport the air outside the oven door body 21 into the cooking cavity.

[0050] Thus, the gas in the cooking cavity can be actively discharged to the outside of the oven door body 21 (which is also the outside of the cooking device 100) through the exhaust component 221, which can improve the gas discharge efficiency in the cooking cavity and help improve the efficiency of the cooking device 100 in removing moisture and water from the cooking cavity; the air outside the cooking device 100 can be actively transported into the cooking cavity through the air supply component 222, thereby quickly increasing the oxygen content in the cooking cavity, helping to increase the aromatic substances produced by the roasted food, and improving the cooking effect of the cooking device 100 on the food.

[0051] It should be noted that the operating states of the exhaust assembly 221 and the air supply assembly 222 can be designed based on the cooking requirements of the cooking device 100. In other words, the exhaust assembly 221 and the air supply assembly 222 can be controlled to operate independently, allowing the exhaust assembly 221 and the air supply assembly 222 to operate independently or simultaneously. For example, when the ventilation assembly 22 opens the first ventilation section 211 and the second ventilation section 212, only the exhaust assembly 221 is in operation, and the exhaust assembly 221 can exhaust the gas in the cooking chamber outward from the first ventilation section 211. Even if the air supply assembly 222 in the second ventilation section 212 is not in operation, the pressure in the cooking chamber is reduced, and air outside the cooking chamber can be supplied into the cooking chamber by generating a negative pressure.

[0052] It can be understood that in the preferred cooking mode of the cooking device 100 of the embodiment of the present application, the exhaust component 221 and the air supply component 222 operate together, and the exhaust rate of the exhaust component 221 and the air delivery rate of the air supply component 222 can be controlled according to the cooking requirements of the food.

[0053] Combine Figure 3 、 Figure 4 and Figure 5 As shown, in a further embodiment of the present application, the ventilation assembly 22 further includes a sealing valve 223 , which is adjustably arranged on the furnace door body 21 , and the sealing valve 223 is provided with a first avoidance opening 2231 and a second avoidance opening 2232 .

[0054] Combine Figure 4 and Figure 5 As shown, when the first avoidance opening 2231 is arranged opposite to the first ventilation part 211, the first ventilation part 211 connects the cooking cavity and the outside of the oven door body 21; when the second avoidance opening 2232 is arranged opposite to the second ventilation part 212, the second ventilation part 212 connects the cooking cavity and the outside of the oven door body 21.

[0055] Thus, the first ventilation portion 211 and the second ventilation portion 212 can be selectively opened by adjusting the position of the sealing valve 223 relative to the oven door body 21. That is, when the first avoidance opening 2231 is offset from the first ventilation portion 211, the sealing valve 223 can block the first ventilation portion 211 through the portion without the avoidance structure, thereby sealing the first ventilation portion 211. In this case, gas in the cooking chamber cannot be discharged outward through the first ventilation portion 211. When the second avoidance opening 2232 is offset from the second ventilation portion 212, the sealing valve 223 can block the second ventilation portion 212 through the portion without the avoidance structure, thereby sealing the second ventilation portion 212. In this case, air cannot be supplied into the cooking chamber through the second ventilation portion 212.

[0056] It will be appreciated that because the relief opening structure (i.e., the aforementioned first relief opening 2231 and second relief opening 2232) is an opening structure on the sealing valve 223, when at least a portion of the relief opening structure and the ventilation structure (i.e., the aforementioned first ventilation portion 211 and second ventilation portion 212) are positioned relative to each other in the arrangement direction, the cooking cavity can be connected to the exterior of the oven door body 21. In other words, the overlapping area of the relief opening structure and the ventilation structure determines the area of connection between the cooking cavity and the exterior of the oven door body 21. Specifically, by adjusting the position of the relief opening structure relative to the ventilation structure, the opening of the ventilation structure can be adjusted.

[0057] Combine Figure 3 and Figure 5 As shown, Figure 3 The sealing valve 223 is in a closed state, that is, the sealing valve 223 blocks the first ventilation portion 211 and the second ventilation portion 212; Figure 4 and Figure 5 As shown, Figure 4 The sealing valve 223 is in an open state, that is, the sealing valve 223 makes the first avoidance opening 2231 face the first ventilation portion 211 , and the second avoidance opening 2232 face the second ventilation portion 212 .

[0058] Combine Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments of the present application, the sealing valve 223 is disposed between the exhaust assembly 221 and the cooking cavity. Thus, when the sealing valve 223 closes the first ventilation portion 211, the area of the sealing valve 223 that blocks the first ventilation portion 211 is located between the exhaust assembly 221 and the cooking cavity, thereby preventing oil and dirt in the cooking cavity from splashing onto the exhaust assembly 221 and protecting the exhaust assembly 221.

[0059] Combine Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments of the present application, the sealing valve 223 is disposed between the air supply assembly 222 and the cooking cavity. Thus, when the sealing valve 223 closes the second ventilation portion 212, the area of the second ventilation portion 212 shielded by the sealing valve 223 is located between the air supply assembly 222 and the cooking cavity, thereby preventing oil and dirt in the cooking cavity from splashing onto the air supply assembly 222 and protecting the exhaust assembly 221.

[0060] Combine Figure 3 、 Figure 4 and Figure 5As shown, the sealing valve 223, the air supply assembly 222 and the exhaust assembly 221 are all arranged on the oven door body 21, and in some preferred embodiments, the sealing valve 223 is arranged on the side of the exhaust assembly 221 adjacent to the cooking cavity, and the sealing valve 223 is also located on the side of the air supply assembly 222 adjacent to the cooking cavity, so that when the first ventilation part 211 and the second ventilation part 212 are closed by the sealing valve 223, the exhaust assembly 221 and the cooking cavity, and the air supply assembly 222 and the cooking cavity can be separated by the sealing valve 223, preventing pollutants such as oil on one side of the cooking cavity from adhering to the air supply assembly 222 and the exhaust assembly 221, thereby improving the protection effect of the air supply assembly 222 and the exhaust assembly 221, and reducing the cleaning frequency of the air supply assembly 222 and the exhaust assembly 221.

[0061] Combine Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments of the present application, the ventilation assembly 22 also includes a slide rail 224, which is arranged on the furnace door body 21, and the sealing valve 223 is slidably arranged on the slide rail 224, and the sealing valve 223 switches between a first position and a second position relative to the furnace door body 21.

[0062] It is understandable that the sealing valve 223 is slidably matched with the slide rail 224, so that the movement of the sealing valve 223 can be guided by the slide rail 224 to limit the movement path of the sealing valve 223 relative to the furnace door body 21. Figure 5 The sealing valve 223 can be constructed as a plate-like structure, and the slide rail 224 is formed with a slide groove. Part of the sealing valve 223 can be embedded in the slide groove, and the sealing valve 223 can slide relative to the slide rail 224 along the extension direction of the slide groove. The slide rail 224 can be fixed on the furnace door body 21.

[0063] Combine Figure 4 and Figure 7 As shown, when the sealing valve 223 is located at the first position, the first avoidance opening 2231 is arranged opposite to the first ventilation portion 211, and the second avoidance opening 2232 is arranged opposite to the second ventilation portion 212; Figure 3 and Figure 6 As shown, when the sealing valve 223 is located at the second position, the sealing valve 223 blocks the first ventilation portion 211 and the second ventilation portion 212 respectively.

[0064] It is understandable that, since the first avoidance opening 2231 is used to open the first ventilation portion 211 and the second avoidance opening 2232 is used to open the second ventilation portion 212, when the first avoidance opening 2231 and the second avoidance opening 2232 are both provided on the same sealing valve 223, the positions of the first avoidance opening 2231 and the second avoidance opening 2232 relative to the furnace door body 21 can be adjusted synchronously. Figure 4 and Figure 7As shown, the first avoidance opening 2231 opens the first ventilation part 211 and the second avoidance opening 2232 opens the second ventilation part 212 at the same time, that is, the distance between the first avoidance opening 2231 and the second avoidance opening 2232 is equal to the distance between the first ventilation part 211 and the second ventilation part 212, so that the opening and closing states of the first ventilation part 211 and the second ventilation part 212 can be adjusted synchronously.

[0065] In some embodiments of the present application, the ventilation assembly 22 further includes a driving device (not shown), which is disposed on the furnace door body 21 and is connected to the sealing valve 223. The driving device is used to drive the sealing valve 223 to slide relative to the slide rail 224 to achieve position adjustment of the sealing valve 223 between the first position and the second position.

[0066] Thus, the driving force can be delivered by the driving device to adjust the position of the sealing valve 223 relative to the furnace door body 21.

[0067] It should be noted that the drive device can be specifically configured as a drive structure such as a drive motor or a hydraulic cylinder, and the drive device can apply a driving force to the sealing valve 223 to adjust the position of the sealing valve 223. For example, if the drive device is configured as a drive motor, the drive motor and the sealing valve 223 can be dynamically connected via a transmission mechanism (e.g., a screw mechanism, a connecting rod mechanism, a rack and pinion mechanism, etc.), thereby transmitting the force generated by the drive motor to the sealing valve 223 via the transmission mechanism.

[0068] In the cooking device 100, the driving device can be electrically connected to the controller in the cooking device 100, so that the working state of the driving device can be controlled in real time according to cooking needs to selectively open or close the first ventilation part 211 and the second ventilation part 212.

[0069] In other embodiments of the present application, the slide rail 224 and the sealing valve 223 are arranged on the side wall of the oven door body 21 away from the cooking cavity, and the slide rail 224 and the sealing valve 223 can be arranged in a position convenient for manual adjustment by the operator.

[0070] It is understandable that when the user needs to adjust the position of the sealing valve 223 relative to the oven door body, the user can adjust the position of the sealing valve 223 relative to the oven door body 21 by manual adjustment on the outside of the cooking device 100, which is also the side of the oven door 2 facing away from the cooking cavity, and the adjustment method is simple.

[0071] In some embodiments of the present application, the slide rail 224 and the sealing valve 223 are arranged on the side wall of the oven door body 21 facing the cooking cavity, and the slide rail 224 and the sealing valve 223 can be arranged in a position convenient for manual adjustment by the operator.

[0072] It is understandable that when the user needs to adjust the position of the sealing valve 223 relative to the oven door body, the oven door 2 can be opened to expose the side surface of the oven door body 21 opposite to the cooking cavity, and the position of the sealing valve 223 relative to the oven door body 21 can be adjusted manually.

[0073] It should be noted that, compared with the solution of arranging the slide rail 224 and the sealing valve 223 on the outside of the oven door body 21, arranging the slide rail 224 and the sealing valve 223 on the side surface of the oven door body 21 facing the cooking cavity can arrange the sealing valve 223 between the exhaust component 221 and the cooking cavity, and between the air supply component 222 and the cooking cavity, so that when the sealing valve 223 closes the first ventilation part 211 and the second ventilation part 212, the exhaust component 221 and the air supply component 222 are blocked by the sealing valve 223 to prevent pollutants such as oil from splashing and adhering to the exhaust component 221 and the air supply component 222.

[0074] In other embodiments of the present application, the interior of the furnace door body 21 is hollow and forms an installation cavity, and the slide rail 224 and the sealing valve 223 are arranged in the installation cavity, thereby saving the arrangement space of the furnace door 2 and improving the space utilization at the furnace door 2.

[0075] When the slide rail 224 and the sealing valve 223 are arranged on the surface of the oven door body 21 facing the cooking cavity, the slide rail 224 and the sealing valve 223 will occupy part of the space in the cooking cavity. When the slide rail 224 and the sealing valve 223 are arranged on the surface of the oven door body 21 facing away from the cooking cavity, the sealing valve 223 will not be able to block the exhaust assembly 221 and the air supply assembly 222 when the first ventilation portion 211 and the second ventilation portion 212 are closed. In this embodiment, the slide rail 224 and the sealing valve 223 can be arranged in the mounting cavity formed by the oven door body 21, thereby reducing the space required for the slide rail 224 and the sealing valve 223. The sealing valve 223 can also be arranged between the exhaust assembly 221 and the cooking cavity, and between the air supply assembly 222 and the cooking cavity.

[0076] It can be understood that the oven door body 21 can be composed of multiple plate structures, and the above-mentioned installation cavity can be defined between two plate structures arranged along the front-to-back direction, thereby improving the space utilization of the oven door 2 while improving the heat insulation effect at the oven door 2 to prevent the heat on one side of the cooking cavity from being conducted outward from the oven door 2.

[0077] like Figure 5 As shown, in some embodiments of the present application, the furnace door 2 further includes: a first air guide cover 231 and a second air guide cover 232 .

[0078] Combine Figure 4 and Figure 5As shown, the first air guide hood 231 is arranged on the first ventilation part 211 and forms a first air duct, the exhaust component 221 is arranged on the side of the first air duct away from the cooking cavity, the second air guide hood 232 is arranged on the second ventilation part 212 and forms a second air duct, and the air supply component 222 is arranged on the side of the second air duct away from the cooking cavity.

[0079] It can be understood that the first air guide hood 231 has a guiding effect on the airflow, and can guide the gas discharged outward from the cooking cavity through the first ventilation part 211 to improve the exhaust effect at the first ventilation part 211; the second air guide hood 232 has a guiding effect on the airflow, and can guide the gas transported into the cooking cavity through the second ventilation part 212 to improve the air supply effect at the second ventilation part 212.

[0080] At the same time, when the oven door main body 21 is formed with the above-mentioned installation cavity, the air guide cover structure (i.e. the above-mentioned first air guide cover 231 and the second air guide cover 232) can block the connecting gaps between the installation cavity and the first ventilation part 211, and between the installation cavity and the second ventilation part 212, thereby preventing pollutants such as oil from entering the installation cavity and guiding the flow direction of the gas, thereby improving the exhaust and air intake effects of the cooking cavity.

[0081] It can be understood that the first air guide cover 231 is arranged corresponding to the exhaust component 221, and the air outlet end of the first air duct is connected to the air inlet side of the exhaust component 221, so that the gas in the cooking cavity can flow to the exhaust component 221 after flowing through the first air duct, and be discharged from the cooking device 100 under the action of the exhaust component 221; the second air guide cover 232 is arranged corresponding to the air supply component 222, and the air inlet end of the second air duct is connected to the air outlet side of the air supply component 222, so that the gas outside the cooking device 100 can be transported to the second air duct through the air supply component 222, and enter the cooking cavity after flowing through the second air duct.

[0082] In some embodiments of the present application, the opening size of the first avoidance opening 2231 is not less than the exhaust port size of the first air duct, so that the first avoidance opening 2231 can fully avoid the first air duct and ensure the exhaust effect at the first air duct.

[0083] In some embodiments of the present application, the opening size of the second avoidance opening 2232 is not less than the air inlet size of the second air duct, so that the second avoidance opening 2232 can fully avoid the second air duct and ensure the air supply effect at the second air duct.

[0084] It can be understood that when the opening size of the first avoidance port 2231 is not less than the exhaust port size of the first air duct and the opening size of the second avoidance port 2232 is not less than the inlet port size of the second air duct, the air intake and outlet effects of the cooking device 100 at the cooking cavity can be guaranteed.

[0085] In some embodiments of the present application, the opening shape and size of the first avoidance port 2231 are the same as the cross-sectional shape and size of the opening of the first ventilation portion 211, so that the first avoidance port 2231 can fully avoid the first ventilation portion 211 to ensure the gas discharge effect at the first ventilation portion 211; the opening shape and size of the second avoidance port 2232 are the same as the cross-sectional shape and size of the opening of the second ventilation portion 212, so that the second avoidance port 2232 can fully avoid the second ventilation portion 212 to ensure the effect of supplying air to the cooking cavity from the second ventilation portion 212.

[0086] like Figure 5 As shown, in some embodiments of the present application, the first ventilation portion 211 and the second ventilation portion 212 are spaced apart on the oven door body 21, thereby improving the air intake and exhaust effects of the cooking cavity.

[0087] It will be appreciated that the first vent 211 is used to exhaust gases (such as high-temperature steam) within the cooking cavity, while the second vent 212 is used to deliver gases into the cooking cavity. Furthermore, since both the first vent 211 and the second vent 212 are formed on the oven door body 21, if the first vent 211 and the second vent 212 are located close together, some of the air entering the cooking cavity at the second vent 212 will be rapidly exhausted from the cooking cavity through the first vent 211, thereby affecting the exhaust of gases from the cooking cavity and reducing the delivery of gases into the cooking cavity. Consequently, the humidity within the cooking cavity and the oxygen content within the cooking cavity cannot be effectively reduced.

[0088] In some embodiments of the present application, the exhaust assembly 221 is configured as a first fan assembly, such as an axial flow fan. The air inlet side of the first fan assembly is connected to one side of the cooking cavity. The first fan assembly can guide the gas in the cooking cavity toward the outside of the cooking device 100, thereby achieving the exhaust function of the cooking device 100.

[0089] In some embodiments of the present application, the air supply assembly 222 is configured as a second fan assembly, such as an axial flow fan. The air outlet side of the second fan assembly is connected to one side of the cooking cavity. The second fan assembly can transport air outside the cooking device 100 into the cooking cavity, thereby achieving the air supply function of the cooking device 100.
