DETAILED DESCRIPTION

[0020] The embodiments of the present application are described in detail below, and 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 cannot be understood as limiting the present application.

[0021] Reference below Figure 1-Figure 7 A cooking device 100 according to an embodiment of the present application is described. The cooking device 100 can be used to cook food.

[0022] The cooking device 100 according to the embodiment of the present application includes: a cooking body 1 and an oven door 2 .

[0023] 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 and the cavity can be used to define a cooking cavity, which is used to place food, and the food can be cooked in the cooking cavity.

[0024] Combination 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 communicating with the cooking cavity and the outside of the oven door body 21, the ventilation assembly 22 is arranged on the oven door body 21, and the ventilation assembly 22 can selectively open or close the first ventilation portion 211 and the second ventilation portion 212, and the ventilation assembly 22 can discharge the gas in the cooking cavity to the outside through one of the first ventilation portion 211 and the second ventilation portion 212 to meet the exhaust demand of the cooking cavity.

[0025] 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. In the process of steam discharge, 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.

[0026] It can be understood that when the first ventilation part 211 and the second ventilation part 212 are connected to the cooking cavity and the outside of the cooking device 100 respectively, the gas in the cooking cavity can be discharged outwardly through the first ventilation part 211 to remove moisture and water in the cooking cavity. In the process of the gas being discharged outwardly 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 is improved.

[0027] It should be noted that, currently, cooking devices (such as steam ovens, microwave ovens, etc.) can steam and bake food. In the related art, when cooking food by steaming, the cooking cavity is usually sealed to prevent steam leakage in the cooking cavity, so that the moisture inside the food cannot be quickly discharged during the cooking process, affecting the dehydration effect of the food, resulting in poor cooking effect of the cooking device on the food.

[0028] 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 is kept sealed during the steaming process, which makes it impossible for the moisture in the dough to be quickly discharged, affecting the dehydration effect of the pasta, making the steamed pasta GI (i.e. glycemic index) higher (e.g. GI value can reach 87), which is not convenient for some people (such as hyperglycemia, diabetes patients, etc.) to eat.

[0029] In the present application, the first ventilation part 211 and the second ventilation part 212 are opened through the ventilation assembly 22, so that the steam in the cooking cavity can be discharged through one of the first ventilation part 211 and the second ventilation part 212, and the air outside the cooking cavity can enter the cooking cavity through the other of the first ventilation part 211 and the second ventilation part 212 to increase the oxygen content in the cooking cavity. In this way, the dough can be dehydrated, thereby increasing the content of slowly digestible starch and resistant starch in the pasta, reducing the glycemic index of the food, and thus producing pasta that meets the needs of patients with hypertension, diabetes, etc.

[0030] 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.

[0031] It should be noted that the cooking device 100 in the present application can be configured as a steam oven or a microwave oven, which is not specifically limited 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 functions such as microwave cooking according to design requirements.

[0032] Furthermore, when the cooking device 100 in the present application has a baking function, the oxygen content in the cooking device 100 can be increased through the ventilation component 22, 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.

[0033] 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.

[0034] It is understandable that when the cooking device 100 is in the steaming cooking state, the moisture and water in the cooking cavity can be discharged through the ventilation component 22 to reduce the water content in the steamed dough, which helps to increase the content of slowly digestible and resistant starch in the dough; when the Mengzhuang device is in the baking cooking state, the moisture and water in the cooking cavity can be discharged through the ventilation component 22, thereby reducing the humidity in the cooking cavity and improving the crispness of the baked food, and the ventilation component 22 can be used to add air to the cooking cavity to increase the oxygen content in the cooking cavity to enhance the aroma of the food. In other words, the cooking device 100 in the present application can control the operating state of the ventilation component 22 according to cooking needs to improve the steaming cooking or baking cooking effect of the cooking device 100 on the food.

[0035] In some embodiments of the present application, the ventilation component 22 includes: an exhaust component 221 and an air supply component 222 .

[0036] 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.

[0037] 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 exhaust 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 aroma substances produced by the roasted food, and improving the cooking effect of the cooking device 100 on the food.

[0038] It should be noted that the working states of the exhaust assembly 221 and the air supply assembly 222 can be designed according to the cooking requirements of the cooking device 100, that is, the exhaust assembly 221 and the air supply assembly 222 can be controlled to work separately, so that the exhaust assembly 221 and the air supply assembly 222 can work separately, and the exhaust assembly 221 and the air supply assembly 222 can also work at the same time. For example: when the ventilation assembly 22 opens the first ventilation part 211 and the second ventilation part 212, only the exhaust assembly 221 works, and the exhaust assembly 221 can discharge the gas in the cooking cavity from the first ventilation part 211 to the outside. Even if the air supply assembly 222 at the second ventilation part 212 is not working, due to the reduction of the pressure in the cooking cavity, the air outside the cooking cavity can also produce negative pressure in the cooking cavity and transport air inward.

[0039] 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.

[0040] Combination 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 disposed 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 .

[0041] Combination 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 with 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 with the outside of the oven door body 21.

[0042] Thus, the first ventilation part 211 and the second ventilation part 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 staggered with the first ventilation part 211, the sealing valve 223 can block the first ventilation part 211 through the part without the avoidance structure to close the first ventilation part 211, and at this time, the gas in the cooking cavity cannot be discharged to the outside through the first ventilation part 211; when the second avoidance opening 2232 is staggered with the second ventilation part 212, the sealing valve 223 can block the second ventilation part 212 through the part without the avoidance structure to close the second ventilation part 212, and at this time, the air cannot be transported into the cooking cavity through the second ventilation part 212.

[0043] It can be understood that, since the avoidance opening structure (i.e., the first avoidance opening 2231 and the second avoidance opening 2232) is an opening structure on the sealing valve 223, when at least part of the avoidance opening structure and the ventilation structure (i.e., the first ventilation part 211 and the second ventilation part 212) are arranged relative to each other in the arrangement direction, the cooking cavity can be connected with the outside of the oven door body 21. In other words, the overlapping area of ​​the avoidance opening structure and the ventilation structure determines the connection area between the cooking cavity and the outside of the oven door body 21, that is, by adjusting the position of the avoidance opening structure relative to the ventilation structure, the opening degree of the ventilation structure can be adjusted.

[0044] Combination 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 opposite to the first ventilation portion 211 , and the second avoidance opening 2232 opposite to the second ventilation portion 212 .

[0045] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of the present application, the sealing valve 223 is arranged between the exhaust assembly 221 and the cooking cavity. Therefore, when the sealing valve 223 closes the first ventilation part 211, the area where the sealing valve 223 blocks the first ventilation part 211 is located between the exhaust assembly 221 and the cooking cavity, which can prevent the oil in the cooking cavity from splashing onto the exhaust assembly 221, thereby protecting the exhaust assembly 221.

[0046] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of the present application, the sealing valve 223 is arranged between the air supply component 222 and the cooking cavity. Therefore, when the sealing valve 223 closes the second ventilation part 212, the area of ​​the second ventilation part 212 shielded by the sealing valve 223 is located between the air supply component 222 and the cooking cavity, which can prevent the oil in the cooking cavity from splashing onto the air supply component 222, thereby protecting the exhaust component 221.

[0047] Combination 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.

[0048] Combination 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 disposed on the furnace door body 21, and the sealing valve 223 is slidably disposed 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.

[0049] It can be understood 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, 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.

[0050] Combination 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.

[0051] It is understandable that, since the first avoidance opening 2231 is used to open the first ventilation part 211 and the second avoidance opening 2232 is used to open the second ventilation part 212, when the first avoidance opening 2231 and the second avoidance opening 2232 are both arranged 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 while the second avoidance opening 2232 opens the second ventilation part 212, 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.

[0052] In some embodiments of the present application, the ventilation assembly 22 also 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.

[0053] 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.

[0054] It should be noted that the driving device can be specifically configured as a driving structure such as a driving motor and a hydraulic cylinder, and the driving device can exert a driving force on the sealing valve 223 to achieve position adjustment of the sealing valve 223. Taking the driving device as a driving motor as an example, the driving motor and the sealing valve 223 can be connected by power through a transmission mechanism (such as a screw mechanism, a connecting rod mechanism, a gear rack mechanism, etc.), so that the force generated by the driving motor is transmitted to the sealing valve 223 through the transmission mechanism.

[0055] 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 requirements to selectively open or close the first ventilation part 211 and the second ventilation part 212.

[0056] 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 at a position convenient for manual adjustment by the operator.

[0057] 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 manually adjust the position of the sealing valve 223 relative to the oven door body 21 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.

[0058] In some embodiments of the present application, the slide rail 224 and the sealing valve 223 are arranged on a 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 at a position convenient for manual adjustment by an operator.

[0059] 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.

[0060] 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 assembly 221 and the cooking cavity, and between the air supply assembly 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 assembly 221 and the air supply assembly 222 are blocked by the sealing valve 223 to prevent pollutants such as oil from splashing and adhering to the exhaust assembly 221 and the air supply assembly 222.

[0061] 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 rate of the furnace door 2.

[0062] 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 of the cooking cavity; when the slide rail 224 and the sealing valve 223 are arranged on the surface of the oven door body 21 away from the cooking cavity, the sealing valve 223 cannot block the exhaust assembly 221 and the air supply assembly 222 when the first ventilation part 211 and the second ventilation part 212 are closed. In this embodiment, the slide rail 224 and the sealing valve 223 can be arranged in the installation cavity formed by the oven door body 21 to save the arrangement space required for the slide rail 224 and the sealing valve 223, and the sealing valve 223 can be arranged between the exhaust assembly 221 and the cooking cavity, and between the air supply assembly 222 and the cooking cavity.

[0063] 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.

[0064] 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 .

[0065] Combination 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 assembly 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 assembly 222 is arranged on the side of the second air duct away from the cooking cavity.

[0066] 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 enhance 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 enhance the air supply effect at the second ventilation part 212.

[0067] At the same time, when the oven door main body 21 forms 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.

[0068] It can be understood that the first air guide hood 231 is arranged correspondingly 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 hood 232 is arranged correspondingly 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] like Figure 5 As shown, in some embodiments of the present application, the first ventilation portion 211 and the second ventilation portion 212 are arranged at intervals on the oven door body 21, thereby improving the air intake and exhaust effects of the cooking cavity.

[0074] It is understandable that the first ventilation portion 211 is used to discharge the gas (such as high-temperature steam, etc.) in the cooking cavity, and the second ventilation portion 212 is used to transport the gas into the cooking cavity. At the same time, since the first ventilation portion 211 and the second ventilation portion 212 are both formed on the oven door body 21, if the distance between the first ventilation portion 211 and the second ventilation portion 212 is relatively close, part of the air entering the cooking cavity at the second ventilation portion 212 will be quickly discharged from the cooking cavity from the first ventilation portion 211, affecting the gas discharge effect in the cooking cavity, and causing the effect of transporting the gas into the cooking cavity to deteriorate, resulting in the inability to effectively reduce the humidity in the cooking cavity and increase the oxygen content in the cooking cavity.

[0075] In some embodiments of the present application, the exhaust assembly 221 is configured as a first fan assembly, such as an axial flow fan, etc. The air inlet side of the first fan assembly is connected to one side of the cooking cavity, and the gas in the cooking cavity can be guided and discharged to the outside of the cooking device 100 under the action of the first fan assembly, thereby realizing the exhaust function of the cooking device 100.

[0076] In some embodiments of the present application, the air supply component 222 is configured as a second fan component, such as an axial flow fan, etc. The air outlet side of the second fan component is connected to one side of the cooking cavity, and the air outside the cooking device 100 can be transported into the cooking cavity under the action of the second fan component, thereby realizing the air supply function of the cooking device 100.

[0078] Table 1: Comparison of the improvement effect of the cooking device 100 in the embodiment of the present application and the comparative example in the prior art In summary, the cooking device 100 according to the embodiment of the present application has at least the following advantages compared with the prior art: (1) The cooking device 100 can discharge the gas in the cooking cavity to the outside to reduce the humidity in the cooking cavity, which helps to reduce the water content of the dough, thereby increasing the content of slowly digestible and resistant starch in the pasta obtained by steaming and cooking the cooking device 100, which can meet the user's cooking needs for low-sugar pasta. At the same time, it can also improve the crispness of the ingredients baked by the cooking device 100, improve the taste of the ingredients, and facilitate the coloring of the ingredients.

[0079] (2) The cooking device 100 can deliver air into the cooking cavity to increase the oxygen content in the cooking cavity, which helps to enhance the aroma substances (such as 2-decenal, 2,4-decadienal, etc.) produced by the food during the cooking process, thereby improving the cooking effect of the cooking device 100 on the food.
