[0003] During the cooking process, anthocyanins and other nutrients in the food react with oxygen in the environment under the promotion of high temperature, resulting in loss of nutrients in the food and poor taste. In order to retain more nutrients in the food, the prior art provides a steam cooking device, which has an exhaust hole at the bottom of the cooking cavity and a steam inlet hole at the top of the cooking cavity.

[0032] Embodiment 1

[0033] The embodiment of the utility model provides a cooking device, which can eliminate or reduce the oxygen in the cooking cavity before cooking, thereby achieving low-oxygen or oxygen-free cooking of food in the cooking cavity, improving the taste of the cooked food, and enhancing the cooking experience.

[0034] like Figure 1 As shown, specifically, the cooking device includes a body, a door, a cooking module and a control device. The body includes a cooking cavity 1 and a housing arranged outside the cooking cavity 1, and the cooking cavity 1 has a cooking cavity with a front opening; the door is movably installed on the front side of the body to selectively close or open the front opening of the cooking cavity; the cooking module is arranged on the body to cook the food in the cooking cavity; the control device is connected to the cooking module in communication to control the operation of the cooking module.

[0035] In this embodiment, the cooking cavity 1 has a circulating exhaust port and a circulating air inlet, and the circulating exhaust port and the circulating air inlet are both connected to the cooking cavity. The cooking device also includes a deoxidation module, which includes a deoxidation device 3 and a fan device 2. The deoxidation device 3 includes a deoxidation chamber and a deoxidation structure. The deoxidation chamber includes at least two deoxidation sub-cavities that are connected in series and connected in sequence. A deoxidation structure is provided in each deoxidation sub-cavity. One of the two deoxidation sub-cavities at both ends is connected to the circulating exhaust port, and the other is connected to the circulating air inlet, so that the deoxidation chamber is connected to the cooking cavity to form a circulating air path; the fan device 2 causes the airflow in the cooking cavity to flow in the circulating air path.

[0036] The cooking device provided by the utility model is provided with a deoxygenating device 3 and a fan device 2, so that the fan device 2 can force the air in the cooking cavity to enter the deoxygenating device 3 for deoxygenation, and the deoxygenated air flows back to the cooking cavity, thereby reducing the oxygen content in the air in the cooking cavity to achieve anaerobic cooking or low-oxygen cooking; at the same time, this arrangement does not need to use hot steam for oxygen exhaust, so that the cooking device can be not only a cooking device with a steam cooking function, but also a cooking device without a steam cooking function, thereby improving the design flexibility of the cooking device; due to the air circulation method inside the cooking cavity, when the air circulates through the deoxygenating device 3. The oxygen is removed at 3, so that the deoxygenation operation can be carried out before cooking, and cooking can be carried out after the deoxygenation is completed. As a result, the air in the cooking chamber is at room temperature during deoxygenation and will not react with the food in the cooking chamber, thereby retaining the nutrients in the food to the greatest extent, improving the taste of cooked food, and improving the user experience of the cooking equipment; furthermore, by setting at least two deoxygenation sub-chambers in series and setting a deoxygenation structure inside each deoxygenation sub-chamber, the probability of air contacting the deoxygenation structure can be increased, and the deoxygenation effect of the deoxygenator 3 on the air can be improved, thereby improving the efficiency of deoxygenating the air in the cooking chamber, shortening the total cooking time, and improving the cooking experience.

[0037] The deoxygenation device 3 includes a shell and a partition plate, a deoxygenation chamber is formed inside the shell, the partition plate is arranged in the deoxygenation chamber and divides the deoxygenation chamber into a plurality of deoxygenation sub-chambers, a plurality of vents are arranged on the partition plate, and two adjacent deoxygenation sub-chambers are connected through the vents so that the airflow flows between the two adjacent deoxygenation sub-chambers. By arranging a plurality of vents on the partition plate, the airflow flowing to the adjacent deoxygenation sub-chambers can be dispersed, thereby further increasing the contact area between the airflow and the deoxygenation structure and improving the deoxygenation effect.

[0038] The partition plate is detachably connected to the shell, which facilitates flexible regulation of the number and size of the deoxygenation sub-cavities and improves the flexibility of setting the deoxygenation device 3. In other embodiments, the partition plate is integrally formed or welded to the shell.

[0039] The shell includes a main box part and a cover part which are connected by snapping. The main box part is provided with a deaerator tank with one side open. The partition plate is installed in the deaerator tank. The cover part is arranged at the open end of the deaerator tank and closes the deaerator tank to form a deaerator chamber. Thus, the deaerator structure inside the deaerator sub-chamber can be replaced by disassembling the cover part relative to the main box part.

[0040] The deoxygenation structure includes a porous medium structure, and a deoxygenator is arranged inside the porous medium structure. When air enters the deoxygenation chamber through the air inlet of the deoxygenation chamber, the air is adsorbed into the porous medium structure, so that the oxygen in the air adsorbed into the porous medium structure reacts chemically with the deoxygenator, thereby achieving deoxygenation of the air. By setting up a porous medium structure and utilizing the adsorption effect of the porous medium structure on air, the contact area between the air and the deoxygenator is increased, thereby reducing the size of the deoxygenation device 3 while improving the deoxygenation effect.

[0041] The deoxidizer is preferably an iron-based deoxidizer, so that the deoxidizer undergoes a redox reaction with oxygen in the air to achieve deoxidation of the oxygen-containing air. The deoxidizer may specifically include a mixture of activated iron powder, diatomaceous earth, hydrated crystalline sodium carbonate and sodium chloride. In other embodiments, the deoxidizer may also be other substances that can adsorb or chemically react with oxygen in the air.

[0042] In order to further improve the deoxygenation effect, a catalyst is provided inside the deoxygenation chamber, and the catalyst is used to catalyze the chemical reaction between the deoxygenator and oxygen to improve the reaction effect and reaction speed, thereby improving the deoxygenation effect. In this embodiment, the deoxygenator is a noble metal catalyst such as platinum or palladium. However, it is understood that the type of catalyst can be specifically selected according to the type of deoxygenator, and the utility model does not make specific limitations on this.

[0043] It is understandable that the specific components of the deoxidizer and the types and components of the catalyst are prior art, and the present utility model does not limit or elaborate on them.

[0044] In this embodiment, the fan inlet of the fan device 2 is connected to the circulating exhaust port, the fan outlet of the fan device 2 is connected to the air inlet of the deaerator chamber, and the outlet of the deaerator device 3 is connected to the circulating air inlet. All deaerator sub-cavities are arranged in sequence along the air outlet direction of the fan outlet, so that the air outlet direction of the fan device 2 is consistent with the arrangement direction of the deaerator sub-cavities, which is conducive to guiding the circulating airflow to flow through multiple deaerator sub-cavities in sequence, reducing the resistance of the airflow circulation, and thus reducing the power required by the fan device 2.

[0045] In other embodiments, the air inlet of the deoxygenation chamber is connected to the circulating exhaust port, the fan air inlet of the fan device 2 is connected to the air outlet of the deoxygenation chamber, the fan air outlet of the fan device 2 is connected to the circulating air inlet, and the arrangement direction of all deoxygenation sub-chambers is consistent with the air inlet direction of the fan air inlet.

[0046] In this embodiment, the number of deoxygenation sub-chambers is preferably set to 2 to 5, that is, 2, 3, 4 or 5, so as to avoid the deoxygenation device 3 being larger in size while ensuring the deoxygenation effect.

[0047] It is worth noting that the air inlet of the deoxygenation chamber is the air inlet of the deoxygenation sub-chamber located at the most upstream of the circulating air path, and the air outlet of the deoxygenation chamber is the air outlet of the deoxygenation sub-chamber located at the most downstream of the circulating air path.

[0048] In this embodiment, the fan outlet of the fan device 2 is perpendicular to the axis of the fan inlet, and the cooking device further comprises an exhaust cavity 6, the exhaust cavity 6 has an exhaust cavity, an air cavity inlet and an air cavity outlet, the air cavity inlet and the air cavity outlet are both connected to the exhaust cavity, and the air cavity inlet is connected to the circulating exhaust port; the fan device 2 is installed outside the exhaust cavity 6, the air cavity outlet is connected to the fan inlet, the fan outlet is connected to the air inlet of the deaerator chamber, and the air outlet of the deaerator chamber is connected to the circulating air inlet. By setting the exhaust cavity 6, the position of the fan inlet can be flexibly set by setting the position of the air cavity outlet of the exhaust cavity 6, thereby improving the convenience of setting the fan device 2.

[0049] Preferably, the fan device 2 can be detachably mounted on the exhaust cavity 6 to ensure the reliability of the connection between the cavity outlet and the fan air inlet.

[0050] In this embodiment, the air outlet of the deoxygenation chamber is connected to the circulating air inlet through the return air pipe 4, and a switch valve is provided on the return air pipe 4, which is used to control the on-off of the return air pipe 4. Therefore, the start and stop of the deoxygenation of the cooking chamber can be controlled by the on-off of the return air pipe 4, thereby ensuring the reliability of the deoxygenation, and at the same time, it is also avoided that during the cooking process, the gas inside the cooking chamber flows back into the deoxygenation device 3 through the return air pipe 4, causing the operation of the deoxygenation device 3 to fail.

[0051] The switch valve is preferably a solenoid valve, and the switch valve is communicatively connected to the control device so that the control device can control the operation of the switch valve.

[0052] In other embodiments, the air inlet of the deoxygenation chamber is connected to the circulating exhaust port through an exhaust pipe, and the air outlet of the deoxygenation chamber is connected to the circulating air inlet through a fan device 2. A switch valve is provided on the exhaust pipe, and the switch valve is used to control the on and off of the exhaust pipe.

[0053] The deoxygenation device 3 also includes an air outlet filter structure, which is used to filter the airflow flowing out of the deoxygenation chamber, thereby preventing the solid particulate matter produced in the deoxygenation chamber from entering the cooking chamber with the flow of air, thereby ensuring the cleanliness of the airflow entering the cooking chamber.

[0054] In one embodiment, the air outlet filter structure can be disposed inside the deoxidation chamber and close to the air outlet of the deoxidation chamber. In another embodiment, the air outlet filter structure can be disposed outside the deoxidation chamber.

[0055] In this embodiment, the cooking device further includes an oxygen sensor 5, which is used to detect the oxygen concentration inside the cooking cavity, so as to determine whether the cooking cavity needs to be deoxygenated, thereby improving the reliability and automation of deoxygenation. The oxygen sensor 5, the switch valve and the fan device 2 are all connected to the control device for communication, and the control device controls the operation of the switch valve and the fan device 2 according to the detection signal of the oxygen sensor 5.

[0056] In this embodiment, the deoxygenator 3 and the fan device 2 are both installed on the outside of the top of the cooking cavity 1, thereby avoiding the deoxygenator 3 from occupying the space on the left and right sides of the cooking cavity 1 and reducing the size requirements of the cooking equipment in the left and right directions; at the same time, setting the deoxygenator 3 and the fan device 2 on the top of the cooking cavity 1 is also beneficial for the cooking cavity 1 to support and fix the deoxygenation module, thereby improving the setting stability and reliability of the deoxygenator 3 and the fan device 2.

[0057] In order to save the overall space occupied by the deoxygenation module, in this embodiment, the circulating exhaust port and the circulating air inlet are both arranged at the top of the cooking cavity 1, and the distance between the circulating exhaust port and the circulating air inlet is greater than the first preset distance. Preferably, the width of the cooking cavity 1 in the front-to-back direction is L, and the first preset distance is greater than or equal to 0.3L, preferably greater than 0.5L. This arrangement can shorten the distance between the circulating exhaust port and the fan device 2, thereby shortening the path length of the circulating air path outside the cooking cavity, reducing the required power of the fan device 2, and further reducing the size requirement of the fan device 2, and reducing the space occupied by the fan device 2.

[0058] Furthermore, the circulating exhaust port and the circulating air inlet are preferably respectively arranged at two diagonal positions on the top of the cooking cavity 1 to increase the distance between the circulating exhaust port and the circulating air inlet as much as possible, thereby avoiding the oxygen-free air entering from the circulating air inlet from being directly discharged through the circulating exhaust port, which is beneficial for the oxygen-free air entering the cooking cavity from the circulating air inlet to mix with the original air in the cooking cavity, thereby improving the deoxygenation effect.

[0059] In other embodiments, the circulating exhaust port and the circulating air inlet may also be set at other positions, as long as the distance between the circulating air inlet and the circulating exhaust port is large, for example, 0.4L, 0.5L, 0.6L, 0.7L, 0.8L, 0.9L, L or 1.1L, etc.

[0060] To ensure the detection accuracy of the oxygen sensor 5, the oxygen sensor 5 is arranged away from the circulating air inlet, that is, the distance between the oxygen sensor 5 and the circulating air inlet is greater than the second preset distance, and the second preset distance is greater than or equal to 0.3L, preferably greater than 0.5L.

[0061] It is worth noting that the cooking equipment provided in this embodiment can be a steam cooking equipment, a microwave cooking equipment or a microwave-steaming integrated equipment, etc. The other structures of the cooking equipment can be set with reference to the prior art. This is not the focus of the present utility model and will not be elaborated here.
