[0002] A steam baking device is a device that adds a steaming function on the basis of an oven. It has both baking and steaming functions and is more functional, so it is more and more widely used in people's daily life. Using steam can transfer heat to food faster. When using a steam baking device to bake food, it is necessary to control the humidity inside the steam baking device. There are existing steam baking devices that use an oxygen sensor to detect the change in oxygen concentration in the steam baking cavity, so as to indirectly reflect the change in water vapor concentration in the steam baking cavity.
[0003] Due to the self-usage characteristics of the oxygen sensor, it is prone to passivation when not in use for a long time. Therefore, it is necessary to regularly inspect the oxygen sensor to ensure its detection accuracy. And, in order to detect the steam content after the work is completed to remind the user to clean or dry, it is necessary to regularly operate the oxygen sensor. However, since the surface temperature of the oxygen sensor is relatively high during operation, the user cannot timely perceive the high temperature when the oxygen sensor is turned on in a non-steam baking mode. If the user cleans the steam baking cavity of the cooking device at this time, it is easy to get scalded when accidentally touching the oxygen sensor.
[0004] Therefore, how to provide a cooking device with high safety is a technical problem that needs to be solved urgently now. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a cooking device, in which the oxygen sensor of the cooking device is not easily touched by the user, the use safety is high, and the user is not easily scalded.

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.
[0029] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0030] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above the top", and "on the top" of the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below the bottom", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal height than the second feature.
[0031] In the description of this embodiment, the terms "upper", "lower", "right", and other orientation or positional relationships are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying operations, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0032] The present utility model provides a cooking device, which has the function of steaming and roasting food. As Figures 1 to 4 shown, the cooking device includes a steaming and roasting main body 100, an oxygen sensor 200, and a heat insulation structure 300. The steaming and roasting main body 100 is the main body structure of the cooking device. The steaming and roasting main body 100 includes an inner container 110, and a cooking cavity 111 is formed in the inner container 110. The cooking cavity 111 is used to place the food to be steamed and roasted and provides the steaming and roasting conditions required for cooking the food. The oxygen sensor 200 is installed in the inner container 110, and at least part of the oxygen sensor 200 is located in the cooking cavity 111. The oxygen sensor 200 is used to detect the humidity in the cooking cavity 111 so that the cooking device can effectively control the humidity in the cooking cavity 111. The heat insulation structure 300 is installed in the inner container 110 and covers at least part of the oxygen sensor 200 exposed in the cooking cavity 111.
[0033] Compared with the prior art where the oxygen sensor is directly exposed in the cooking cavity of the inner container, not only is there no protection for the oxygen sensor, making the oxygen sensor vulnerable to damage, but also the oxygen sensor is easily accidentally touched by the user, resulting in scalding accidents. The cooking device provided by the present utility model sets a heat insulation structure 300 in the inner container 110 and covers the heat insulation structure 300 outside the structure of the oxygen sensor 200 exposed in the inner container 110. The heat insulation structure 300 is used to protect and isolate the oxygen sensor 200. Thus, it can not only avoid water entering the probe chip of the oxygen sensor 200 when wiping the inner container 110, causing damage to the oxygen sensor 200 and extending the service life of the oxygen sensor 200, but also avoid mechanical damage to the oxygen sensor 200 and isolate the user's touch on the oxygen sensor 200. For example, during the inspection process of the oxygen sensor 200, even if the user cleans the cooking cavity 111, they will not touch the oxygen sensor 200, so scalding accidents will not occur, improving the use safety of the cooking device.
[0034] In addition to the inner container 110, the steaming and baking main body 100 further includes an outer shell. The outer shell covers the inner container 110. Optionally, the outer shell is a plastic part. By setting the outer shell as a plastic part, it helps to reduce the overall weight of the cooking device, making the cooking device easy to move. The outer shell can not only protect the inner container 110, but also prevent users from directly contacting the inner container 110, avoiding scalding users by the inner container 110 at a relatively high temperature. In some embodiments, both the outer shell and the inner container 110 are cube-shaped, and a pick-up and placement opening for food to enter and exit is formed at the front of the inner container 110. An opening is formed at the front of the outer shell. The steaming and baking main body 100 further includes a door body. The door body is rotatably connected to one side of the housing and is disposed at the opening of the outer shell and the pick-up and placement opening of the inner container 110 in an openable and closable manner. Of course, in other embodiments, the steaming and baking main body 100 can also be set in other shapes according to requirements, which is not limited herein.
[0035] In addition to the inner container 110 and the outer shell, the steaming and baking main body 100 further includes a heating mechanism and a steam generator (not shown in the figure). The steam generator and the heating mechanism can jointly create a cooking environment with a target temperature and a target humidity in the cooking cavity 111. It should be noted that the structure and working principle of the steam generator are both prior arts and will not be described in detail herein.
[0036] In some embodiments, the heating mechanism includes an electric heating tube 120 installed on the inner container 110. In one embodiment, the electric heating tube 120 is disposed on the inner top wall of the inner container 110. In one embodiment, a plurality of electric heating tubes 120 are provided, and the plurality of electric heating tubes 120 are evenly distributed on the inner top wall of the inner container 110. In one embodiment, the electric heating tube 120 is a tubular structure formed by splicing a straight tube and a curved tube; in another embodiment, the electric heating tube 120 is a coiled tube.
[0037] Continue to refer to Figure 1 and Figure 2 As shown, in some embodiments, the oxygen sensor 200 and the heat insulation structure 300 are both disposed on the top of the inner container 110. Such a setting reduces the probability of the oxygen sensor 200 and the heat insulation structure 300 coming into contact with food. Of course, in other embodiments, the oxygen sensor 200 and the heat insulation structure 300 can also be disposed on the rear side, left side or right side of the inner container 110.
[0038] In some embodiments, the inner container 110 includes a top plate 112 located at the top. Fixing holes are provided on the top plate 112, and the oxygen sensor 200 is fixed in the fixing holes. The probe of the oxygen sensor 200 passes through the fixing hole from top to bottom and is placed in the cooking cavity 111. The heat insulation structure 300 is covered outside the probe from bottom to top. Such an arrangement enables the oxygen sensor 200 and the heat insulation structure 300 to be relatively easily assembled onto the inner container 110. It should be noted that the specific structure of the oxygen sensor 200 is prior art. The oxygen sensor 200 includes a probe and a chip, etc., which will not be elaborated here.
[0039] Continuing to refer to Figure 4 As shown, the heat insulation structure 300 includes a covering part 310. The covering part 310 covers the probe of the oxygen sensor 200, and a hole-like structure is formed on the covering part 310. The hole structure communicates the inside of the covering part 310 with the cooking cavity 111. The setting of the covering part 310 does not affect the collection of gas in the cooking cavity 111 by the oxygen sensor 200, so that the setting of the covering part 310 does not affect the detection of the humidity in the cooking cavity 111 by the oxygen sensor 200. In one embodiment, the heat insulation structure 300 includes a plurality of filamentous members, and the covering part 310 in a net-like structure is formed by braiding or welding the plurality of filamentous members, and a hole structure is formed between adjacent filamentous members.
[0040] In some embodiments, the covering part 310 is hemispherical; in some parallel embodiments, the covering part 310 is a columnar structure with one end open; in some parallel embodiments, the covering part 310 is a structure with both ends open. It should be noted that one opening of the covering part 310 is for the oxygen sensor 200 to enter the covering part 310, and the size of the other opening needs to ensure that the user's finger cannot enter the covering part 310 and touch the oxygen sensor 200.
[0041] In some embodiments, continuing to refer to Figure 3 As shown, the maximum size a of the hole structure on the covering part 310 is less than or equal to 5 mm. Optionally, a can be 5 mm, 4 mm, 3 mm, 2 mm or 1 mm. Of course, a is not limited to these values and can be other values within the range, as long as it is ensured that even if the user's finger touches the heat insulation structure 300, it will not touch the oxygen sensor 200 through the heat insulation structure 300.
[0042] In some embodiments, the covering part 310 is a metal mesh cover. By making the covering part 310 of a metal material, the covering part 310 can withstand high temperatures during cooking and does not need to be disassembled due to being unable to withstand high temperatures. Exemplarily, the covering part 310 is a wire mesh made of iron wire. Of course, in other embodiments, the covering part 310 can also be made of other non-metallic materials with high temperature resistance properties.
[0043] Continue to refer to Figure 3 and Figure 4 As shown, the heat insulation structure 300 further includes a mounting ring plate portion 320 disposed circumferentially along the open end of the covering portion 310. The mounting ring plate portion 320 contacts and connects with the inner container 110, thereby fixing the heat insulation structure 300 to the inner container 110.
[0044] In one embodiment, the cooking device further includes a fastener 400. The mounting ring plate portion 320 and the inner container 110 are detachably connected through the fastener 400. Optionally, the fastener 400 passes through the mounting ring plate portion 320 and the inner container 110 to mount the heat insulation structure 300 on the inner container 110.
[0045] In some embodiments, the longitudinal section of the mounting ring plate portion 320 is L-shaped, which includes a first ring plate 321 and a second ring plate 322 connected at an angle. The first ring plate 321 is used for fixedly connecting with the inner container 110, and the second ring plate 322 is used for connecting with the covering portion 310.
[0046] In some embodiments, the fastener 400 includes a screw 410 and a nut 420. The screw 410 is disposed through the top plate 112 of the inner container 110 and the mounting ring plate portion 320 from top to bottom, and the nut 420 is threadedly connected to the penetrating end of the screw 410. Optionally, a plurality of first mounting holes are formed through the top plate 112 of the inner container 110, and a plurality of second mounting holes 3211 are provided on the first ring plate 321. The plurality of second mounting holes 3211 and the plurality of first mounting holes are arranged in one-to-one correspondence. The plurality of screws 410 are respectively disposed through the plurality of groups of second mounting holes 3211 and the first mounting holes, and the plurality of nuts 420 are respectively threadedly connected to the penetrating ends of the plurality of screws 410. In addition to using screws 410 and nuts 420, the fastener 400 can also adopt a snap structure.
[0047] In some parallel embodiments, the mounting ring plate portion 320 and the top plate 112 of the inner container 110 can also be fixed by a magnetic component. In this way, it is convenient to realize the quick assembly and disassembly of the heat insulation structure 300 and the inner container 110. In one embodiment, an annular first magnet sheet is arranged around the oxygen sensor 200 on the top plate 112, and an annular second magnetic sheet is provided on the first ring plate 321, or the first ring plate 321 directly forms the second magnet sheet, and the first magnet sheet and the second magnet sheet can be magnetically attracted.
[0048] Continue to refer to Figure 4As shown, in some embodiments, the minimum distance b between the probe of the oxygen sensor 200 and the heat insulation structure 300 is greater than 10 mm and less than 50 mm. By keeping the distance between the heat insulation structure 300 and the probe of the oxygen sensor 200 above 10 mm, such a setting can reduce the temperature of the heat insulation structure 300 when the oxygen sensor 200 is working, so that the user will not be scalded. By limiting the distance between the heat insulation structure 300 and the probe of the oxygen sensor 200 to less than 50 mm, the setting of the heat insulation structure 300 will not occupy too much of the cooking cavity 111.
[0049] Continue to refer to Figure 4 As shown, in some embodiments, the minimum distance c between the heating tube 120 and the heat insulation structure 300 is greater than 10 mm and less than 100 mm. By keeping the distance between the heating tube 120 and the probe of the oxygen sensor 200 above 10 mm, such a setting can reduce the temperature of the heat insulation structure 300 when the heating tube 120 is working, so that the user will not be scalded. By limiting the distance between the heating tube 120 and the probe of the oxygen sensor 200 to less than 100 mm, it is beneficial to maintain the structural compactness of the entire cooking device.
[0050] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
