Detailed implementation manners

[0041] Existing steam ovens use a steam generation device and a heating device to steam or bake the food in the steam baking inner tank. After the steam oven finishes working, generally, the door panel of the steam oven is directly closed, and the heat remaining in the steam oven is used to evaporate the water vapor during the food cooking process, or the door panel is opened for ventilation to increase the gas flow in the steam oven and thus accelerate the water vapor evaporation process. However, both of these methods cannot monitor the humidity value in the steam oven in real time. Therefore, it is impossible to determine whether the remaining heat in the steam oven is sufficient to evaporate the remaining water vapor completely, and it is impossible to adjust the specific ventilation time of opening the door panel according to the humidity value. Therefore, not only the efficiency of discharging the remaining water vapor is reduced, but also the workload of the user for maintaining the steam oven is increased. If the remaining water vapor is not discharged thoroughly, it will induce mildew and generate peculiar smell in the steam oven, and cause the structural parts made of metal materials to rust, reducing the comfort of the user experience and the service life of the steam oven.

[0042] In view of this, in the embodiment of the present invention, a dehumidifying component and a humidity detection device are arranged in the steaming and baking inner container, and the humidity detection device is used to monitor the humidity value in the steaming and baking inner container in real time, so as to facilitate the user to timely obtain the humidity situation in the steaming and baking inner container during and after the operation of the steaming and baking oven. The dehumidifying component is used to effectively reduce the humidity value in the steaming and baking inner container. By arranging the humidity detection device and the dehumidifying component on the opposite sides of the steaming and baking inner container respectively, the influence of the dehumidifying component on the humidity detection device during operation is avoided, thus ensuring the accuracy of humidity detection. Therefore, after the operation of the steaming and baking oven is completed, it can prevent a large amount of water vapor from accumulating in the steaming and baking inner container and being unable to be discharged, prevent the humidity in the inner container of the steaming and baking oven from being too high, and avoid the occurrence of situations such as mildew and peculiar smell, and rust of metal structural parts, thereby optimizing the comfort of the user experience of the steaming and baking oven and prolonging the service life of the steaming and baking oven.

[0045] Embodiment 1

[0046] Figure 1 is the front view of the steaming and baking oven provided by Embodiment 1 of the present invention. Figure 2 is the side view of the steaming and baking oven provided by Embodiment 1 of the present invention. Figure 3 is the exploded view of the steaming and baking oven provided by Embodiment 1 of the present invention. Figure 4 is the structural schematic diagram of a part of the accommodation cavity of the steaming and baking oven provided by Embodiment 1 of the present invention. Figure 5 is the top view of a part of the accommodation cavity of the steaming and baking oven provided by Embodiment 1 of the present invention. Figure 6 is the external structural schematic diagram of the steaming and baking inner container of the steaming and baking oven provided by Embodiment 1 of the present invention.Figure 7 It is a schematic internal structure diagram of the steaming and baking inner container of the steaming and baking oven provided by Embodiment 1 of the present invention.

[0047] Referring to Figures 1 to 7 As shown, Embodiment 1 of the present invention provides a steaming and baking oven 100, which includes a housing 10 and a steaming and baking inner container 20 for holding food to be steamed and baked. The steaming and baking inner container 20 is located inside the housing 10, and a dehumidification component and at least one humidity detection device 24 are provided in the steaming and baking inner container 20. The humidity detection device 24 and at least part of the dehumidification component are respectively located on opposite sides in the steaming and baking inner container 20.

[0048] The dehumidification component includes a heating device 40 and a dehumidification fan 60. At least part of the heating device 40 is located on one side of the steaming and baking inner container 20 close to the dehumidification fan 60.

[0049] It should be noted that in the steaming and baking oven 100 provided in this embodiment, a containing cavity 30 is located between the steaming and baking inner container 20 and the housing 10. The shape and volume of the containing cavity 30 can be set as needed, and this embodiment does not limit this. Referring to Figure 1 and Figure 2 As shown, a door panel 70 is provided on one side of the housing 10 facing the user. When in use, the door panel 70 can be opened to expose the steaming and baking inner container 20, facilitating the user to place or take out ingredients. This embodiment does not limit the opening or closing method of the door panel 70. The housing 10 protects the steaming and baking inner container 20 and at the same time surrounds the steaming and baking inner container 20 to prevent the high-temperature steaming and baking inner container 20 from being exposed outside, threatening the personal safety of the user.

[0050] The steaming and baking inner container 20 is inside the housing 10 and a heating device 40 is provided in the steaming and baking inner container 20. A steam generating device 50, a heat dissipation device 90 and a control device 80 are provided in the containing cavity 30. The control device 80 is electrically connected to the heating device 40 and the steam generating device 50 respectively. When the steaming and baking oven 100 works, the control device 80 controls and supplies power to the heating device 40, the steam generating device 50 and the heat dissipation device 90. After the heating device 40 is powered on, it radiates heat into the steaming and baking inner container 20 to bake the ingredients on the baking tray 23 in the steaming and baking inner container 20. After the steam generating device 50 is powered on, it generates steam, and the steam enters the steaming and baking inner container 20 through the air inlet 21 of the steaming and baking inner container 20, and the steam contacts the ingredients for steaming. After the heat dissipation device 90 is powered on, the first heat dissipation fan 91 located at the top of the steaming and baking inner container 20 conveys air flow to the top of the steaming and baking inner container 20, and the second heat dissipation fan 92 located at the bottom of the steaming and baking inner container 20 conveys air flow to the bottom of the steaming and baking inner container 20. The air flow is used to perform heat exchange with the top and bottom of the steaming and baking inner container 20 respectively, thereby reducing the overall temperature of the steaming and baking inner container 20.

[0051] Among them, at least one humidity detection device 24 is provided in the steaming and baking inner container 20. The humidity detection device 24 can be a humidity sensor, which is used to obtain the humidity value in the steaming and baking inner container 20 in real time. The humidity detection device 24 can be electrically connected to the control device 80, so as to facilitate sending the detected humidity value information to the control device 80. A plurality of humidity detection devices 24 can be provided, and the plurality of humidity detection devices 24 can be arranged at different positions in the steaming and baking inner container 20 according to the needs of users. The specific number of the humidity detection devices 24 in this embodiment is not limited.

[0052] A dehumidification component is also provided in the steaming and baking inner container 20. The dehumidification component can include a heating device 40 and a dehumidification fan 60. Those skilled in the art can understand that accelerating the evaporation of water vapor can be achieved by two methods: increasing the temperature and accelerating the air flow. In view of this, in this embodiment, the heating device 40 is provided to increase the temperature in the steaming and baking inner container 20, and the dehumidification fan 60 can increase the air flow in the steaming and baking inner container 20, so as to accelerate the evaporation of the remaining water vapor.

[0053] Based on this, the working process of the dehumidification component will increase the evaporation of the remaining water vapor. Therefore, in this embodiment, the dehumidification component and the humidity detection device 24 are respectively arranged on the opposite sides of the steaming and baking inner container 20, so as to effectively avoid the influence of the dehumidification component on the accuracy of the humidity detection device 24 during the working process.

[0054] Furthermore, at least part of the heating device 40 can be arranged on the side of the steaming and baking inner container 20 close to the dehumidification fan 60, so that the dehumidification fan 60 can carry the heat of the heating device 40 into the steaming and baking inner container 20, thereby effectively avoiding the heat of the heating device 40 being only concentrated near the heating device 40, ensuring that the heat of the heating device 40 is evenly distributed in the whole steaming and baking inner container 20, thereby increasing the temperature of the whole steaming and baking inner container 20, accelerating the evaporation process of the remaining water vapor, and effectively reducing the humidity value of the steaming and baking inner container 20.

[0055] Specifically, the humidity detection device 24 and at least part of the dehumidification component are respectively located on two opposite side walls of the steaming and baking inner container 20.

[0056] It should be noted that the temperature of the remaining water vapor in the steaming and baking inner container 20 is relatively high, mainly concentrated in the middle or top of the steaming and baking inner container 20. Therefore, if the humidity detection device 24 is arranged at the top of the steaming and baking inner container 20, the humidity detection result will be higher than the actual value, and if the humidity detection device 24 is arranged at the bottom of the steaming and baking inner container 20, the humidity detection result will be lower than the actual value. Therefore, in this embodiment, the humidity detection device 24 is arranged on the side wall of the steaming and baking inner container 20, so as to obtain a more balanced humidity value in the steaming and baking inner container 20 and avoid the influence of the installation position of the humidity detection device 24 on the accuracy of the humidity detection result.

[0057] Moreover, at least a part of the dehumidifying component is also located on the side wall of the steaming and baking inner container 20 and on the side wall opposite to the humidity detection device 24, so that the distance between the dehumidifying component and the top and bottom of the steaming and baking inner container 20 is approximately equal. Thus, the heat generated by the heating device 40 and the air flow generated by the dehumidifying fan 60 in the dehumidifying component can act on the top or bottom of the steaming and baking inner container 20 simultaneously, increasing the acting area of the dehumidifying component and thereby improving the dehumidifying effect of the dehumidifying component.

[0058] As a feasible implementation manner, with reference to Figure 5 as shown, in response to the above description, in this embodiment, the humidity detection device 24 is arranged at the middle or near the middle position in the vertical direction of any one of the two relatively arranged side walls.

[0059] Furthermore, a first cooling fan 91 is arranged at the top of the steaming and baking inner container 20, and a second cooling fan 92 is arranged at the bottom. Therefore, arranging the humidity detection device 24 at the middle or near the middle position of the side wall of the steaming and baking inner container 20 can effectively avoid the first cooling fan 91 and the second cooling fan 92, reducing the installation difficulty of the steam oven 100 and at the same time preventing the operation processes of the first cooling fan 91 and the second cooling fan 92 from affecting the detection result of the humidity detection device 24.

[0060] In the above-mentioned steam oven 100, optionally, the heating device 40 includes a first heating element 41 located at the top of the steaming and baking inner container 20 and a second heating element 42 located at the bottom of the steaming and baking inner container 20.

[0061] It should be noted that the first heating element 41 provided in this embodiment can be heating tubes arranged in a mesh array and / or a ring array on the top of the steaming and baking inner container 20. The heating tubes can be metal heat-conducting tubes with an antioxidant film plated on the surface, and wiring ports can be arranged at both ends of the heating tubes for convenient electrical connection with the control device 80. Among them, a plurality of heating wires are distributed in the heating tubes, and after being powered on, they can generate heat to radiate heat to the steaming and baking inner container 20. In actual use, the arrangement manner of the first heating element 41 can be set according to actual needs, and this embodiment does not limit this.

[0062] The first heating element 41 has a first heating surface facing the middle of the steaming and baking inner container 20, and the first heating surface covers the top of the steaming and baking inner container 20. Based on the setting of the first heating element 41 at the top of the steaming and baking inner container 20, during the operation of the first heating element 41, not only will heat be radiated to the first heating surface, but also part of the heat will be radiated into the accommodating cavity 30, resulting in a relatively high temperature near the top of the steaming and baking inner container 20 in the accommodating cavity 30. In response to this, a wind guiding plate assembly is further provided in the accommodating cavity 30 of this embodiment. At least one heat dissipation area is enclosed in the accommodating cavity 30 by the wind guiding plate assembly. The heat dissipation area can be set according to the position of the main heating elements in the accommodating cavity 30. The heating elements may include, but are not limited to, the steam generating device 50, the control device 80 in the accommodating cavity 30, and the high-temperature area in the accommodating cavity 30. Among them, the high-temperature area in the accommodating cavity 30 may be the area near the heating device 40 in the steaming and baking inner container 20 in the accommodating cavity 30. The heat dissipation area can be used to dissipate heat from the heating elements and the high-temperature area in the accommodating cavity 30 in a targeted manner, thereby improving the heat dissipation efficiency of the heat dissipation air flow generated by the heat dissipation device 90.

[0063] In this embodiment, a first wind guiding plate 31 is provided in the area near the top of the steaming and baking inner container 20 in the accommodating cavity 30. The first wind guiding plate 31, the top wall of the steaming and baking inner container 20, and the inner wall of the housing 10 jointly enclose a first heat dissipation area 33. The first heat dissipation area 33 is mainly distributed near the top position of the steaming and baking inner container 20, and the first heat dissipation area 33 is communicated with the air outlet of the first heat dissipation fan 91. When the first heat dissipation fan 91 operates, the heat dissipation air flow generated can flow to the top of the steaming and baking inner container 20 in the accommodating cavity 30 under the guidance of the first wind guiding plate 31, so as to exchange heat with the top of the steaming and baking inner container 20, thereby reducing the temperature of the top area of the steaming and baking inner container 20 and avoiding the influence of excessive temperature in this area on the working stability of the entire steam oven 100.

[0064] Furthermore, in combination with that shown in Embodiment 3 Figure 9 When the steam oven 100 is integrated into the integrated stove 200, the gas stove 202 of the integrated stove 200 is provided at the top of the steam oven 100, and cookware 203 will be placed on the gas stove 202, and this area is the main operation area for users to cook. Therefore, reducing the temperature at the top of the steam oven 100 helps to maintain the use stability of the gas stove 202 and ensure the personal safety of users.

[0065] Specifically, at least two wind guiding sections include a first wind guiding section 311 extending along the length direction of the steaming and baking inner container 20 and a second wind guiding section 312 extending along the width direction of the steaming and baking inner container 20. The first end of the first wind guiding section 311 is connected to the air outlet of the first heat dissipation fan 91, the second end of the first wind guiding section 311 is connected to the first end of the second wind guiding section 312, and the second end of the second wind guiding section 312 extends in a direction away from the first heat dissipation fan 91.

[0066] It should be noted that the second heating element 42 can be the same heating tube as the first heating element 41 or a heating plate. The second heating element 42 has a second heating surface 421 facing the middle of the steaming and baking inner container 20, and the second heating surface 421 covers the bottom of the steaming and baking inner container 20. The second heating surface 421 can be the surface covered by the whole heating tube or the plate surface of the heating plate. Setting the second heating surface 421 to face the middle of the steaming and baking inner container 20 can facilitate the radiation of the heat on the second heating surface 421 towards the middle of the steaming and baking inner container 20, so as to bake the food. In actual use, the user can selectively turn on any one or both of the first heating element 41 and the second heating element 42 as needed to achieve the cooking of the food, and this embodiment does not limit this.

[0067] Further, referring to Figure 7 As shown, the heating device 40 includes a third heating element 43 located on the side wall of the steaming and baking inner container 20. The third heating element 43 and the humidity detection device 24 are respectively arranged on two opposite side walls of the steaming and baking inner container 20. The third heating element 43 and the dehumidifying fan 60 are located on the same side wall of the steaming and baking inner container 20.

[0068] Specifically, the third heating element 43 is arranged in a multi-layer coil shape and is wound around the outer periphery of the dehumidifying fan 60.

[0069] It should be noted that the third heating element 43 can be a heating tube arranged in a multi-layer coil shape. The arrangement method of being arranged in a multi-layer coil shape and located around the dehumidifying fan 60 can effectively save the installation space required by the third heating element 43 and improve the space utilization rate in the steaming and baking inner container 20. In actual use, the number of layers of the arrangement of the third heating element 43 can be set as needed, and this embodiment does not limit this.

[0070] A dehumidifying fan 60 is arranged on one side of the third heating element 43 in the steaming and baking inner container 20, and the air outlet of the dehumidifying fan 60 faces the middle of the steaming and baking inner container 20. It should be noted that the dehumidifying fan 60 in this embodiment can be an axial flow fan or a centrifugal fan, and this embodiment does not limit the specific type of the dehumidifying fan 60. The dehumidifying fan 60 and the third heating element 43 are located on the same side, and the air outlet of the dehumidifying fan 60 faces the middle of the steaming and baking inner container 20. Such a setting can use the dehumidifying fan 60 to deliver the heat generated by the third heating element 43 to the middle of the steaming and baking inner container 20, avoiding the concentration of heat near the third heating element 43 in the steam oven 100, so as to evenly distribute the heat in the steaming and baking inner container 20, so that the residual water vapor in the steaming and baking inner container 20 can contact the heat of the third heating element 43 to complete the evaporation process.

[0071] As an implementable embodiment, a plurality of heat conducting members are provided on the outer wall of the third heating member. The heat conducting member can be fins spaced on the outer wall of the third heating member 43. By using the heat conducting member, the heat radiation area of the third heating member 43 can be increased, thereby increasing the heat radiated by the third heating member 43 to the outside and enhancing the heating efficiency of the third heating member 43. The number of fins provided in this embodiment is not limited.

[0072] Further, referring to Figure 6 As shown, there is a receiving cavity 30 between the steaming and baking inner container 20 and the housing 10. The steaming and baking inner container 20 has at least one exhaust port 22 communicating with the receiving cavity 30. At least one exhaust port 22 is disposed close to the dehumidifying fan 60.

[0073] It should be noted that the residual water vapor can be evaporated and removed by the heating device 40 that raises the temperature. When the water vapor content in the steaming and baking inner container 20 is relatively large, the water vapor can be discharged into the receiving cavity 30 through the exhaust port 22 at the same time. A plurality of exhaust ports 22 can be provided, and the plurality of exhaust ports 22 are disposed in the receiving cavity 30 according to user needs. The number of exhaust ports 22 in this embodiment is not limited.

[0074] Among them, at least one exhaust port 22 is disposed on one side close to the dehumidifying fan 60. Such a setting enables the dehumidifying fan 60 to drive the water vapor to be discharged into the receiving cavity 30 through the exhaust port 22 that is relatively close to the dehumidifying fan 60 when working, thereby reducing the flow path of the water vapor in the receiving cavity 30, reducing the residence time of the water vapor in the steaming and baking inner container 20, and accelerating the discharge process of the water vapor.

[0075] Specifically, the setting height of the exhaust port 22 close to the dehumidifying fan 60 is higher than the setting height of the dehumidifying fan 60. It should be noted that the temperature of the water vapor after the steaming oven 100 finishes working is relatively high, and it mainly floats in the middle or near the top of the steaming and baking inner container 20. Therefore, setting the height of the exhaust port 22 higher than the setting height of the dehumidifying fan 60 is conducive to the floating steam being discharged through the exhaust port 22 under the driving of the air flow of the dehumidifying fan 60. In actual use, the specific setting heights of the dehumidifying fan 60 and the exhaust port 22 can be set according to needs, and this embodiment does not limit this.

[0076] Further, based on the above description, in this embodiment, the water vapor in the steaming and baking inner container 20 is discharged into the receiving cavity 30 through the exhaust port 22. However, a large number of electronic components are also provided in the receiving cavity 30. If water vapor accumulates in the receiving cavity 30, it will cause faults in the electronic components and rust the structural members made of metal materials, which is also not conducive to the working stability of the steaming oven 100. A plurality of ventilation ports 11 communicating the receiving cavity 30 with the outside are provided on the housing 10, and the ventilation ports 11 are communicated with at least one exhaust port 22. At least one ventilation port 11 is disposed close to the top of the housing 10.

[0077] It should be noted that, in this embodiment, a plurality of ventilation openings 11 are provided on the housing 10 to facilitate the timely discharge of water vapor in the accommodation cavity 30 to the outside of the accommodation cavity 30. A plurality of ventilation openings 11 communicating the accommodation cavity 30 with the outside are provided on the housing 10 of the steam oven 100 of this embodiment. Among them, the plurality of ventilation openings 11 include at least one first ventilation opening 111 provided near the top of the steam cooking inner container 20. The air inlet of the first cooling fan 91 faces the steam generating device 50. The first cooling area 33 communicated with the air outlet of the first cooling fan 91 is communicated with the first ventilation opening 111.

[0078] It should be noted that the first ventilation opening 111 can be located at the top position of the housing 10 near the steam cooking inner container 20, so as to facilitate communication with the first cooling area 33 in the accommodation cavity 30, reduce the length of the discharge path of the high-temperature cooling air flow in the first cooling area 33, and thus reduce the secondary influence of the high-temperature air flow on the electronic components in the accommodation cavity 30. At the same time, the air inlet of the first cooling fan 91 faces the steam generating device 50, so that when the first cooling fan 91 works, the gas flow around the steam generating device 50 can be strengthened, the heat accumulation around the steam generating device 50 can be avoided, and the working stability of the steam generating device 50 can be ensured.

[0079] Furthermore, the plurality of ventilation openings 11 may further include at least one second ventilation opening 112 provided near the bottom of the steam cooking inner container 20. The air outlet of the second cooling fan 92 faces the second ventilation opening 112, which is convenient for discharging the water vapor concentrated at the bottom in the accommodation cavity to the outside of the accommodation cavity 30 through the second ventilation opening 112.

[0080] Furthermore, the air guiding plate assembly may further include a second air guiding plate 32 provided at the bottom of the steam cooking inner container 20, and the second air guiding plate 32 separates the second cooling fan 92 and the steam generating device 50. Among them, the second air guiding plate 32 is separated between the second cooling fan 92 and the steam generating device 50. Based on the fact that the air inlet of the first cooling fan 91 faces the steam generating device 50, the first air guiding plate 31 can effectively prevent the cooling air flow at the air inlet of the first cooling fan 91 from interfering with the cooling air flow at the air inlet of the second cooling fan 92, thereby avoiding the problem that the cooling air flow circulates repeatedly in the accommodation cavity 30 and affecting the cooling effect. Further, through the second air guiding plate 32, it can effectively prevent the water vapor discharged from the steam cooking inner container 20 into the accommodation cavity 30 from flowing back and forth with the cooling air flow in the accommodation cavity 30, thereby reducing the flow path and accumulation time of the water vapor in the accommodation cavity 30.

[0081] Embodiment 2

[0082] Figure 8 is a schematic flow chart of the control method of the steam oven provided in the second embodiment of the present invention. Refer toFigure 8 As shown in the figure, on the basis of the above-mentioned first embodiment, the second embodiment of the present invention provides a control method for a steam oven.

[0083] Specifically, the control method for the steam oven is used to control the steam oven in the first embodiment. The control method for the steam oven includes:

[0084] S1: When the steam oven is turned off, turn off the steam generating device of the steam oven according to the steam oven off information.

[0085] S2: Obtain the real-time humidity in the steaming and baking inner cavity of the steam oven and the working duration of the dehumidification component.

[0086] S3: When the real-time humidity in the steaming and baking inner cavity is lower than or equal to the preset humidity, and / or when the working duration of the dehumidification component is greater than or equal to the preset duration, turn off the dehumidification component.

[0087] The control method for the steam oven provided in this embodiment immediately turns off the steam generating device of the steam oven when the steam oven is turned off, that is, turns off the steam generating source of the steam oven. At this time, the dehumidification component is still working. This can avoid the influence of steam generation on the dehumidification process, reduce steam waste, and reduce the operating cost of the steam oven.

[0088] At the same time, as an implementable embodiment, the real-time humidity in the steaming and baking inner cavity is obtained by using the humidity detection device in the steam oven. When the real-time humidity is lower than the preset humidity, the dehumidification component is turned off. The preset humidity can be set according to user needs. For example, it can be set to the humidity point of 70%. Under this humidity and room temperature conditions, it is generally the suitable growth humidity and temperature for most molds. Therefore, setting the preset humidity to this value in this embodiment can effectively inhibit the growth of most molds. Further, the preset humidity can also be a humidity range value, such as 70% ± 5%. The specific numerical value and form of the preset humidity in this embodiment are not limited, nor are they limited to the above examples. Such a setting method can ensure that the dehumidification component is turned off with a delay, and ensure that the dehumidification component still guarantees the dehumidification effect during the cooling process when the steam oven stops working.

[0089] As another implementable embodiment, the working duration of the dehumidification component can be obtained by using the timing device of the steam oven. When the working duration is greater than the preset duration, the dehumidification component is turned off. The working duration can be set according to user needs. For example, it is the time point of 3 minutes, or the time period of 3 - 5 minutes. The specific numerical value and form of the preset duration in this embodiment are not limited, nor are they limited to the above examples. Such a setting method can also ensure that the dehumidification component is turned off with a delay, and during the delayed turn-off period, the dehumidification component can still be used to ensure the dehumidification effect of the steam oven.

[0090] In actual use, the dehumidification component can be closed in any one or both of the above two ways.

[0091] Other technical features are the same as those in the first embodiment and can achieve the same or corresponding technical effects, which will not be elaborated here one by one.

[0092] The control method of the steam oven provided in the second embodiment of the present invention immediately closes the steam generating device when the steam oven is closed, and at the same time delays the closing of the dehumidification component to avoid continuous generation of steam affecting the dehumidification process; at the same time, the real-time humidity of the steam oven and / or the working duration of the dehumidification component are obtained. By using the delayed closing of the dehumidification component, it is ensured that during the cooling process after the steam oven finishes working, there is still a dehumidification component working to ensure the dehumidification effect, thereby improving the reduction of the humidity value in the steam oven, avoiding mildew inside it, rusting of metal structural parts, and generation of peculiar smells, prolonging the service life of the steam oven, and optimizing the comfort of the user experience of the steam oven.

[0093] Embodiment Three

[0094] Figure 9 is a schematic structural diagram of the integrated stove provided in the third embodiment of the present invention. Refer to Figure 9 As shown, on the basis of the above-mentioned first embodiment or the second embodiment, the third embodiment of the present invention provides an integrated stove.

[0095] It should be noted that the steam oven 100 can be arranged in the integrated stove 200. The integrated stove 200 can further include a gas stove 202 arranged on the operation tabletop on the top of the steam oven 100 (pots and pans 203 can be placed on the operation tabletop or the gas stove 202), and an oil fume extractor 201 arranged on the top of the whole integrated stove 200. The control device 80 of the steam oven 100, the gas stove 202, and the oil fume extractor 201 can all be electrically connected to the control device of the integrated stove 200, so as to realize the integrated linkage control of the integrated stove 200, improving the operability and use convenience of the integrated stove 200.

[0096] Among them, the oil fume extractor 201 is located at the top of the integrated stove 200 and can suck the steam generated by the steam oven 100 and discharge it through the air outlet at the bottom of the integrated stove 200, avoiding the high-temperature air flow and steam in the accommodation cavity 30 staying in the kitchen for a long time, avoiding the high-temperature air flow affecting the heat dissipation effect of the steam oven 100, and at the same time avoiding the reverse leakage of steam into the steam oven 100 to prevent the problem of flavor mixing of the ingredients in the steam oven 100.

[0097] Of course, an exhaust system is provided in the integrated cooking stove 200 body. The exhaust system is connected to the accommodation cavity 30 of the steam oven 100, facilitating the discharge of the high-temperature air flow and steam in the accommodation cavity 30 through the exhaust system, thereby improving the heat dissipation effect of the steam oven 100, preventing the steam from affecting the taste of the food, and maintaining the normal use of the electronic components in the accommodation cavity 30.

[0098] Other technical features are the same as those in the first embodiment or the second embodiment, and can achieve the same or corresponding technical effects, which will not be elaborated here one by one.

[0099] The integrated cooking stove provided in the third embodiment of the present invention is provided with a dehumidification component and a humidity detection device in the steaming and baking inner container of the steam oven. The humidity detection device is used to monitor the humidity value in the steaming and baking inner container in real time, so as to facilitate the user to timely obtain the humidity situation in the steaming and baking inner container during and after the operation of the steam oven. The dehumidification component is used to effectively reduce the humidity value in the steaming and baking inner container. By respectively arranging the humidity detection device and the dehumidification component on the opposite sides in the steaming and baking inner container, the influence of the dehumidification component on the humidity detection device during operation is avoided, thus ensuring the accuracy of humidity detection. Therefore, this steam oven can avoid a large amount of water vapor accumulating in the steaming and baking inner container and being unable to be discharged after the operation, prevent the humidity in the inner container of the steam oven from being too high, and avoid the occurrence of mildew, peculiar smell, rust of the structural parts made of metal materials, etc., thereby optimizing the comfort of the user experience of the steam oven and prolonging the service life of the steam oven and the integrated cooking stove.
