[0027] Embodiment 1

[0028] 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.

[0029] like Figure 1 As shown, specifically, the cooking device includes a body, a door 10, a cooking module and a control module 9. The body includes an inner pot 1 and a housing arranged outside the inner pot 1, and the inner pot 1 has a cooking cavity with a front opening; the door 10 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 module 9 is connected to the cooking module in communication to control the operation of the cooking module.

[0030] In this embodiment, the cooking device further includes a deoxygenation module. Specifically, the inner pot 1 has an air inlet and an air outlet, both of which are connected to the cooking cavity; the deoxygenation module includes an air supply device 2 and a deoxygenation device 3, the air outlet of the deoxygenation device 3 is connected to the air inlet, the air supply device 2 is used to force the air outside the cooking device to flow through the inside of the deoxygenation device 3 and then enter the cooking cavity, and the deoxygenation device 3 is used to remove oxygen from the air supplied thereto.

[0031] The cooking device provided by the utility model is provided with a deoxygenating device 3 and an air supplying device 2, so that the external air enters the cooking cavity after being deoxygenated by the deoxygenating device 3, and the oxygen-containing air in the cooking cavity is forced to be discharged from the cooking cavity through the exhaust port under the action of air pressure, thereby replacing the oxygen-containing air in the cooking cavity with the deoxygenated air, reducing the oxygen content in the cooking cavity, and thus realizing 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; furthermore, since the gas in the cooking cavity is exhausted by external air, and the external air is at room temperature and will not react with the food in the cooking cavity, the oxygen exhaust operation can be performed before cooking, and cooking can be performed after the oxygen exhaust is completed, thereby retaining the nutrients in the food to the greatest extent, improving the taste of the cooked food, and improving the user experience of the cooking device.

[0032] The air outlet of the deoxygenating device 3 is connected to the air inlet through the air supply pipe 5. The air supply pipe 5 is provided with a switch valve 4, which is used to control the on and off of the air supply pipe 5, and the switch valve 4 is connected to the control module 9. By setting the switch valve 4, the selective air supply to the inside of the cooking cavity can be controlled, so as to control the selective deoxygenation of the gas inside the cooking cavity by the deoxygenating module; at the same time, the setting of the switch valve 4 can also prevent the gas inside the cooking cavity from flowing back to the deoxygenating device 3 through the air supply pipe 5 during the cooking process, thereby affecting the deoxygenation function of the deoxygenating device 3.

[0033] In this embodiment, the air inlet of the air supply device 2 is connected to the external environment of the cooking device, and the air outlet of the air supply device 2 is connected to the air inlet of the deoxidation device 3. The air supply device 2 promotes the external air flow to flow through the air supply device 2, the deoxidation device 3, the air supply pipe 5 and the cooking cavity in sequence. That is, in this embodiment, the air supply device 2 blows the external air flow into the deoxidation device 3 to perform deoxidation.

[0034] In other embodiments, the air supply device 2 can also be arranged at the air supply pipe 5, that is, the air inlet of the deoxygenation device 3 is connected to the external environment, the air outlet of the deoxygenation device 3 is connected to the air inlet of the air supply device 2, and the air outlet of the air supply device 2 is connected to the air inlet of the air supply pipe 5, that is, the air supply device 2 is an exhaust fan.

[0035] In order to improve the convenience of installing the deoxygenation module in the machine body, in the present embodiment, the deoxygenation device 3 and the air supply device 2 are both arranged on the top outer side of the inner pot 1, thereby avoiding the deoxygenation device 3 from occupying the space on the left and right sides of the inner pot 1, and reducing the size requirements of the cooking equipment in the left and right directions; at the same time, arranging the deoxygenation device 3 and the air supply device 2 on the top of the inner pot 1 is also conducive to the inner pot 1 to support and fix the deoxygenation module, thereby improving the setting stability and reliability of the deoxygenation device 3.

[0036] In this embodiment, an air inlet is provided at the front side of the cooking device, and the air inlet of the air supply device 2 is directly opposite to the air inlet, and the air inlet of the air supply device 2 is connected to the external space at the front side of the cooking device through the air inlet. Since the front space of the cooking device is always open, this arrangement can ensure the smoothness of the air supply device 2 in introducing external air, and prevent the air supply of the air supply device 2 from being affected by the installation position and installation environment of the cooking device.

[0037] In other embodiments, an air inlet may also be provided at other locations of the cooking device, as long as it is ensured that external air can be introduced into the air supply device 2 through the air inlet.

[0038] The control module 9 is installed at the top of the front side of the machine body and is located above the machine door 10. When the machine door 10 is in a closed state, the air inlet is located between the lower end of the control module 9 and the top end of the machine door 10. Specifically, the machine body also includes a door frame arranged at the front side of the inner tank 1, the control module 9 is installed on the door frame, and the door frame is provided with the above-mentioned air inlet.

[0039] In order to further improve the smoothness of external air entering the deoxygenation device 3, in this embodiment, the air supply device 2 includes a blower 21 and an air inlet container 22. The air inlet container 22 is installed on the top of the inner liner 1 and has a container air inlet and a container air outlet. The container air inlet is arranged opposite to the air inlet; the blower 21 is installed on the outside of the air inlet container 22, and the fan air inlet of the blower 21 is connected to the container air outlet, and the fan air outlet of the blower 21 is connected to the air inlet of the deoxygenation device 3. That is, the fan air inlet of the blower 21 is arranged downward, and the fan air outlet of the blower 21 is arranged backward. By setting the air inlet container 22, the air inlet of the blower 21 can achieve blowing without facing the fan inlet, which reduces the requirements for the installation position and type of the blower 21, and is conducive to the docking between the air inlet and the air inlet of the air supply device 2.

[0040] In other embodiments, the air supply device 2 may only include a blower 21 , wherein the air inlet of the blower 21 is arranged forward and directly connected to the air inlet, and the air outlet of the blower 21 is arranged backward and connected to the deoxygenation device 3 .

[0041] In order to improve the docking convenience between the air inlet container 22 and the air inlet, the air inlet container 22 is a flat container, and the height of the air inlet container 22 in the vertical direction is smaller than the dimensions of the air inlet container 22 in the left-right direction and the front-to-back direction, so that the height of the container air inlet port of the air inlet container 22 is relatively smaller than the width in the front-to-back direction, which is conducive to matching the size of the container air inlet port with the size of the air inlet.

[0042] Furthermore, an air inlet filter structure is provided inside the air inlet container 22, and the air inlet filter structure is used to filter the airflow entering the blower 21 to reduce the probability of impurities such as ash layers blocking the blower 21 or the deoxidation device 3, and improve the deoxidation reliability of the deoxidation module. The air inlet filter structure can be, but is not limited to, a filter net.

[0043] The deoxygenation device 3 includes a shell, a deoxygenation chamber is arranged inside the shell, the deoxygenation chamber has an air chamber inlet and an air chamber outlet, the air inlet is used to let in external air, and the air chamber outlet is connected to the air inlet. A porous medium structure is arranged inside the deoxygenation chamber, and a deoxygenator is coated on the surface of the porous medium structure. Specifically, in this embodiment, the air chamber inlet is connected to the air outlet of the fan.

[0044] When external air enters the deoxygenation chamber through the air inlet, the air is adsorbed into the porous medium structure. Since the surface of the porous medium structure is coated with a deoxygenator, the oxygen in the air adsorbed into the porous medium structure reacts chemically with the deoxygenator, thereby achieving air deoxygenation. By setting up a porous medium structure, the adsorption of air through the porous medium structure is facilitated, and 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.

[0045] 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. In other embodiments, the deoxidizer may also be other substances that can adsorb or chemically react with oxygen in the air.

[0046] In order to further improve the deoxygenation effect, a catalyst is provided inside the deoxygenation chamber, and the catalyst is used to catalyze the 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 specifically limit this.

[0047] To further improve the deoxygenation effect, in this embodiment, the deoxygenation device 3 includes at least two deoxygenation units connected in series, and the air supply device 2 causes the external air to flow through all the deoxygenation units in sequence, and each deoxygenation unit can deoxygenate the air passing through it. By providing at least two deoxygenation units, the contact area between the air and the deoxygenation substance inside the deoxygenation unit can be increased, and the deoxygenation path can be extended, thereby improving the deoxygenation effect.

[0048] Specifically, in the present embodiment, the deoxygenation chamber is separated by a partition plate to form at least two sub-cavities, and a vent is provided on the partition plate, and two adjacent sub-cavities are connected through the vent. A deoxygenating substance is provided inside each sub-cavity, and the deoxygenating substance is used to deoxygenate the air entering the sub-cavity. The deoxygenating substance includes the above-mentioned porous medium structure, deoxygenator and catalyst. That is, each sub-cavity and the deoxygenating substance inside it form a deoxygenation unit. Therefore, when the air passes through each sub-cavity in turn, it reacts with the deoxygenating substance inside it and is deoxygenated, which effectively avoids the problem that the deoxygenating substance is centrally arranged, making it difficult for some air to react with the deoxygenating substance, and increases the probability of contact between the air and the deoxygenating substance, thereby improving the deoxygenation effect.

[0049] All the sub-air chambers are preferably arranged in sequence along the front-to-back direction, so that the frontmost sub-air chamber is connected to the fan outlet of the blower 21, and the rearmost sub-air chamber is connected to the air supply pipe 5, so that the arrangement direction of the sub-air chambers is consistent with the air supply direction from the blower 21 to the air supply pipe 5, which is conducive to the flow of air in each sub-air chamber, reduces air flow resistance, and improves the convenience of connecting the deoxygenation device 3 with the air supply pipe 5 and the blower 21. In other embodiments, all the sub-air chambers can also be arranged in sequence along the left-right direction or arranged in sequence along the vertical direction.

[0050] Furthermore, the deoxygenation device 3 also includes an air outlet filter structure, which is used to filter the air flow out of the deoxygenation chamber, thereby preventing the solid particulate matter produced in the deoxygenation chamber from entering the air supply pipe 5, the switch valve 4 or the cooking chamber with the flow of air, avoiding the switch valve 4 from being blocked, and ensuring the cleanliness of the air flow entering the cooking chamber.

[0051] In one embodiment, the air outlet filter structure can be arranged inside the deoxygenation chamber and close to the air chamber outlet. In another embodiment, the air outlet filter structure can be arranged between the switch valve 4 and the deoxygenation device 3.

[0052] In this embodiment, the cooking device further includes an oxygen sensor 7, 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 7, the switch valve 4 and the air supply device 2 are all communicatively connected to the control module 9, and the control module 9 controls the operation of the switch valve 4 and the air supply device 2 according to the detection signal of the oxygen sensor 7.

[0053] In this embodiment, the air inlet is arranged at the lower part of the cooking cavity, and the oxygen sensor 7 is arranged at the top of the inner pot 1, thereby avoiding the problem of reduced oxygen concentration detection accuracy caused by the oxygen sensor 7 being close to the air inlet, and increasing the distance between the oxygen sensor 7 and the air inlet, which is conducive to making the oxygen concentration value detected by the oxygen sensor 7 closer to the average oxygen concentration value in the cooking cavity, thereby improving the detection accuracy.

[0054] It is worth noting that the air inlet being located at the lower part of the cooking cavity means that the height between the air inlet and the bottom of the inner pot 1 is less than half of the height of the inner pot 1 .

[0055] In this embodiment, the exhaust port and the air inlet are respectively located on different side walls of the inner pot 1 to increase the distance between the exhaust port and the air inlet, thereby preventing the deoxygenated air entering from the air inlet from being directly discharged through the exhaust port without mixing with the air in the cooking cavity.

[0056] In this embodiment, the cooking module includes a steam generating device 8, which is used to generate hot steam and send the hot steam into the cooking cavity, so as to cook the food in the cooking cavity by the heat of the hot steam. The specific structure of the steam generating device 8 and its arrangement inside the machine body can be set with reference to the prior art, which is not the focus of the present invention and will not be described in detail here.

[0057] The cooking device further includes an exhaust device disposed on the top of the inner pot 1, the air outlet is connected to the exhaust device through the exhaust pipe 6, and the exhaust device is connected to the external environment. In the deoxygenation stage, the air inside the cooking cavity can be discharged to the outside of the cooking device through the exhaust port, the exhaust pipe 6 and the exhaust device in sequence; during the steam cooking process or after the steam cooking is completed, the steam in the cooking cavity can be discharged to the external device through the exhaust port, the exhaust pipe 6 and the exhaust device in sequence. The exhaust device can adopt the setting of the exhaust device in the existing steam cooking device, and this embodiment does not limit the specific type and structure of the exhaust device.

[0058] 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.

[0059] Embodiment 2

[0060] This embodiment provides a cooking device, and the cooking device provided in this embodiment is a further improvement based on the cooking device in the first embodiment. This embodiment will not repeat the same contents as the first embodiment.

[0061] In this embodiment, a three-way joint is provided between the air inlet of the deaerator 3 and the air outlet of the air supply device 2, the first port of the three-way joint is connected to the air outlet of the air supply device 2, the second port of the three-way joint is connected to the air inlet of the deaerator 3, and the third port of the three-way joint is connected to the air supply pipe 5 through a bypass pipe. A bypass control valve is provided on the bypass pipe.

[0062] The cooking device has a steam cooking function. According to the above arrangement, after steam cooking is completed, air can be supplied into the cooking cavity through the air supply device 2 and the air supply pipe 5, so that the high-temperature steam in the cooking cavity can be discharged through the exhaust port, thereby preventing the high-temperature steam from spreading on the surface and scalding the user when the machine door 10 is opened, thereby improving the safety and user experience of the cooking device; by setting a bypass pipe, when steam is discharged, it is possible to choose whether to deoxygenate the air entering the cooking cavity according to the type of food, thereby preventing the food that is easily oxidized at high temperature from reacting with the oxygen in the air entering the cooking cavity during the steam discharge process and affecting the taste; at the same time, for the food that is not easy to oxidize after cooking, it is not necessary to deoxygenate the air entering the cooking cavity, thereby increasing the service life of the deoxygenator 3, reducing the maintenance and replacement costs of the deoxygenator 3, and reducing the use cost of the cooking device.
