[0038] In the prior art, the machine head of the integrated cooker plays a role in gathering smoke during oil fume suction. In order to facilitate cleaning of the cavity inside the machine head, the smoke baffle installed on the machine head is designed to be easily detachable. Due to the easy-to-detach design and manufacturing reasons, there is a gap between the smoke baffle and the placement surface below it. At the same time, in order to enable the oil fume and water vapor sucked by the machine head to flow smoothly into the air bellow and prevent oil stains from dripping onto the placement surface, a back side of the smoke baffle is designed with a lining plate structure to guide the oil and water to flow into the air bellow and then into the oil box. There is also a gap between the lining plate and the opposite side surface. When suctioning smoke, air flow will flow through the above two gaps in turn, and the wind speed of the air flow will gradually increase, resulting in a whistling sound under the interaction of the air flow.

[0039] Please refer to Figure 1 To solve the technical problem of whistling sound during suctioning of smoke, the present application provides an integrated cooker 1000, which comprises a machine base 200, a cooker 300 and a smoke exhaust device 100. The cooker 300 is arranged on the machine base 200, and the smoke exhaust device 100 is also arranged on the machine base 200. The smoke suction port 202 of the smoke exhaust device 100 can be arranged towards the cooker 300, so that the smoke exhaust device 100 can suck the smoke generated by the cooker 300 during cooking.

[0040] It can be understood that the top of the machine base 200 can have a mounting table, which can be a horizontal surface, so that the cooker 300 can be arranged on the mounting table, and the smoke exhaust device 100 is also arranged on the mounting table. The cooker 300 is located in the central area of the mounting table, and the smoke exhaust device 100 is arranged adjacent to the cooker 300. The side of the integrated cooker 1000 facing the user is the front side, and the side facing away from the user is the rear side. The smoke exhaust device 100 is located on the side of the cooker 300 close to the rear side, and the smoke suction port 202 of the smoke exhaust device 100 is located above the cooker 300. The smoke suction port 202 can exhaust the smoke generated by the cooker 300. The smoke exhaust device 100 comprises a smoke baffle assembly 10, which can eliminate the whistling sound generated during suction of oil fume.

[0041] Optionally, the integrated cooker 1000 can further comprise a cooking device, which can be arranged inside the machine base 200 and below the cooker 300. Taking a steam oven as an example, the cooking device can also be a steam oven, a steam oven, a micro steam oven, etc.

[0042] In the second aspect, please refer to Figure 1 and Figure 2A smoke exhaust device 100 provided by the embodiment of the application includes a head 20, a smoke baffle assembly 10, a wind box 30 and a fan assembly 40. The head 20 has a smoke suction port 202, and the smoke baffle assembly 10 is detachably installed on the head 20. The smoke baffle assembly 10 and the head 20 can form a smoke exhaust air duct 201 in communication with the smoke suction port 202. The wind box 30 can be connected with the head 20, and the wind box 30 has a smoke exhaust port 301, and a smoke exhaust cavity 302 is formed in the wind box 30. The smoke exhaust cavity 302 can communicate the smoke exhaust air duct 201 and the smoke exhaust port 301. The fan assembly 40 can be arranged in the smoke exhaust cavity 302. When the fan assembly 40 works, it can suck the smoke from the smoke suction port 202 into the smoke exhaust cavity 302 and exhaust it from the smoke exhaust port 301.

[0043] It can be understood that the smoke baffle assembly 10 is installed on the front side of the head 20, and the smoke baffle assembly 10 can jointly define the smoke exhaust air duct 201 with the head 20. The smoke exhaust air duct 201 extends vertically. The head 20 can be connected to the top of the base 200, so that the head 20 can protrude upward relative to the top of the base 200, so that the smoke suction port 202 on the head 20 can be located above the cooking appliance 300, facilitating the smoke suction port 202 to suck the smoke generated by the cooking appliance 300. The wind box 30 can be arranged on the base 200, and the wind box 30 is located behind the base 200. The wind box 30 is also in communication with the smoke exhaust air duct 201 in the head 20. The smoke exhaust port 301 is located on the side of the wind box 30, so that the smoke exhaust port 301 can be in communication with an external smoke pipe. The smoke exhausted from the smoke exhaust port 301 can be exhausted along the smoke pipe to the outside. The fan assembly 40 can be arranged in the smoke exhaust cavity 302.

[0044] Structure Figure 3 The lower edge 11 of the smoke baffle assembly 10 and the placement surface below it will have a first gap 12. When the fan assembly 40 works, the fan assembly 40 can suck the smoke from the smoke suction port 202 into the smoke exhaust air duct 201, Figure 2 The solid arrows in the smoke exhaust air duct 201 indicate the direction of the smoke flow. The smoke flows into the smoke exhaust cavity 302 under the guidance of the smoke baffle assembly 10 and is exhausted to the outside. There will be airflow flowing into the smoke exhaust air duct 201 from the first gap 12, but the airflow will not flow through other gaps, but directly into the smoke exhaust cavity 302 along the smoke exhaust air duct 201 and be exhausted to the outside. The smoke baffle assembly 10 in the application can eliminate the howling sound generated when sucking the oil fume.

[0045] Optionally, the side of the head 20 facing the user is provided with a clamping plate, and the smoke baffle assembly 10 is clamped on the clamping plate. Without tools, the smoke baffle assembly 10 can be detached, facilitating the user to take down the smoke baffle assembly 10 for cleaning.

[0046] Third aspect, please refer to Figure 3 and Figure 4A smoke baffle assembly 10 provided by the embodiment of the present application includes a smoke baffle 1 having a lower edge 11 and a backing plate 2 connected to the back side of the smoke baffle 1, the back side of the smoke baffle 1 refers to the side of the smoke baffle 1 and the machine head 20 jointly defining the smoke exhaust air duct 201, or in other words, the back side of the smoke baffle 1 refers to the side facing away from the user, the backing plate 2 includes a flow guide plate 21, the flow guide plate 21 is arranged at an angle with the smoke baffle 1, the lower end of the flow guide plate 21 is spaced apart from the smoke baffle 1, and the lower end of the flow guide plate 21 is higher than the lower edge 11.

[0047] In the embodiment, the smoke baffle 1 is detachably arranged on the machine head 20 of the integrated cooker 1000 to make the smoke baffle 1 and the machine head 20 define the smoke exhaust air duct 201, the smoke baffle 1 and the machine head 20 have a first gap 12 therebetween, the backing plate 2 is connected to the back side of the smoke baffle 1, that is, the backing plate 2 is located in the smoke exhaust air duct 201, the backing plate 2 includes the flow guide plate 21, the flow guide plate 21 is arranged at an angle with the smoke baffle 1, and the lower end of the flow guide plate 21 is spaced apart from the smoke baffle 1, so that the flow guide plate 21 gradually moves away from the smoke baffle 1 along the direction of the smoke flowing in the smoke exhaust air duct 201, and the lower end of the flow guide plate 21 is higher than the lower edge 11, so that the flow guide plate 21 as a whole is located above the first gap 12, or in other words, the projection of the flow guide plate 21 on the smoke baffle 1 is located in the smoke baffle 1, so that the flow guide plate 21 only has a second gap 13 with the smoke baffle 1, and one end of the second gap 13 is sealed.

[0048] Structure Figure 2 When the machine head 20 is sucking the oil fume, the smoke suction port 202 can suck the smoke into the smoke exhaust air duct 201, the smoke flows downward along the smoke exhaust air duct 201, in this process, the oil fume and water will adhere to the smoke baffle 1, and the oil fume and water will flow downward along the smoke baffle 1, the oil fume and water will flow in the direction away from the first gap 12 under the guidance of the flow guide plate 21, so that the oil fume and water can smoothly flow into the oil box, and under the suction force of the fan assembly 40, combined with the fact that the lower end of the flow guide plate 21 is higher than the lower edge 11, the oil fume and water will flow into the oil box through the second gap 13. Figure 3 There will be airflow flowing from the first gap 12 into the smoke exhaust air duct 201, Figure 3 The dashed arrow in the figure indicates the direction of airflow, Figure 3 The solid arrow in the figure indicates the direction of smoke flow, since one end of the second gap 13 is sealed, that is, the second gap 13 cannot form a channel for the airflow to pass through, so that the airflow passing through the first gap 12 will not flow to the second gap 13, but directly enter the smoke exhaust chamber 302 along the smoke exhaust air duct 201 and be discharged to the outside, so that the airflow will only pass through one gap.

[0049] It should be noted that, through experiments, it is verified that, in the case that the airflow only passes through one gap, no matter the size of the gap, the airflow will not produce whistling, and thus the main reason for the whistling is that the airflow passes through one gap and then passes through another gap, and thus when the airflow passing through the first gap 12 does not flow to the second gap 13, the whistling sound produced when the oil fume is sucked can be eliminated.

[0050] Referring to Figure 4 and Figure 5 In some embodiments, the backing plate 2 further comprises a fixing plate 22, the flow guide plate 21 is connected to the smoke baffle 1 through the fixing plate 22, and the flow guide plate 21 is arranged at an angle with the fixing plate 22.

[0051] Optionally, the fixing plate 22 is a long straight plate, the fixing plate 22 is arranged at an angle with the backing plate 2, and the fixing plate 22 is connected to the backing plate 2, a plurality of mounting holes can be arranged on the fixing plate 22, the plurality of mounting holes are sequentially and spacedly arranged along the length direction of the lower edge 11, a plurality of bolts are respectively inserted into the plurality of mounting holes, and the plurality of bolts are connected to the smoke baffle 1, so that the fixing plate 22 is fixed to the smoke baffle 1, and the flow guide plate 21 is arranged at an angle with the smoke baffle 1, and in other embodiments, the fixing plate 22 can be directly welded to the smoke baffle 1.

[0052] In some embodiments, the fixing plate 22 can be integrally formed with the flow guide plate 21.

[0053] Exemplarily, a large metal plate can be bent by means of a bending machine, a bending die and the like to process the fixing plate 22 and the flow guide plate 21, and the fixing plate 22 and the flow guide plate 21 processed by the bending process have high structural strength and are very convenient to process.

[0054] Referring to Figure 3 In some embodiments, the distance between the lower end of the flow guide plate 21 and the smoke baffle 1 is d, and d is greater than or equal to 3 mm.

[0055] It can be understood that when part of the oil fume and water vapor adheres to the smoke baffle 1 and flows downward along the smoke baffle 1, the flow guide plate 21 is used to guide the part of the oil fume and water vapor to flow away from the first gap 12, so as to prevent the oil fume and water vapor from dropping onto the placement surface below the lower edge 11, and in order to ensure that the flow guide plate 21 can play the above-mentioned role, the distance between the lower end of the flow guide plate 21 and the first gap 12 needs to be kept a certain distance d, when d is less than 3 mm, the lower end of the flow guide plate 21 is close to the smoke baffle 1, and when the oil fume and water vapor flow out from the lower end of the flow guide plate 21, it is still possible to flow into the first gap 12 and drop onto the placement surface below the lower edge 11, and thus when d is greater than or equal to 3 mm, the flow guide plate 21 can guide the oil fume and water vapor adhering to the smoke baffle 1 to flow into the smoke exhaust duct 201, so as to prevent the smoke from flowing to the first gap 12.

[0056] Please refer to Figure 2 and Figure 4 In some embodiments, the smoke baffle assembly 10 further comprises a hanging bracket 3 connected to the back side of the smoke baffle 1.

[0057] Exemplarily, the smoke baffle 1 can be hung on the hood 20 through the hanging bracket 3, so that the smoke baffle 1 and the hood 20 define the smoke exhaust air duct 201. When it is necessary to clean the oil stains in the smoke exhaust air duct 201, the smoke baffle 1 can be easily disassembled by detaching the hanging bracket 3 from the hood 20, and the oil stains can be easily cleaned. Therefore, the hanging bracket 3 serves as a connecting component, which can stably install the smoke baffle 1 on the hood 20 and facilitate disassembly when cleaning is needed.

[0058] In this embodiment, two hanging brackets 3 are connected to the back side of the smoke baffle 1, and the two hanging brackets 3 are respectively arranged near the left and right side edges of the smoke baffle 1. The two hanging brackets 3 can be respectively hung on the frames on the two sides of the hood 20, so that the smoke baffle 1 and the hood 20 are more stably connected.

[0059] Please continue to refer to Figure 2 and Figure 4 In some embodiments, the bottom of the hanging bracket 3 is provided with a hanging interface 31, which is arranged towards the lower edge 11 of the smoke baffle 1. When the smoke baffle 1 is installed on the hood 20, the smoke baffle 1 can be simply placed on the side of the hood 20 from top to bottom, and the hanging bracket 3 can be clamped with the frame on the hood 20 through the hanging interface 31, so that the installation is very convenient. When it is necessary to clean the oil stains in the smoke exhaust air duct 201, the smoke baffle 1 can be disassembled by lifting it from bottom to top, which is very convenient.

[0060] Please refer to Figure 4 In some embodiments, the deflector 21 is arranged along the length direction of the lower edge 11, and the ratio a of the length of the deflector 21 to the length of the smoke baffle 1 satisfies 1>a≥0.8.

[0061] It should be noted that, when the smoke is sucked, the smoke in the smoke exhaust air duct 201 will flow from top to bottom, and part of the oil fume and water vapor will adhere to the smoke baffle 1, and the part of the oil fume and water vapor will flow along the smoke baffle 1 to the deflector 21. In order to guide the part of the oil fume and water vapor to smoothly flow out and prevent the part of the oil fume and water vapor from flowing to the first gap 12, the length of the deflector 21 needs to be long enough so that the deflector 21 can be located in the flow path of the part of the oil fume and water vapor. Therefore, the ratio a of the length of the deflector 21 to the length of the smoke baffle 1 needs to satisfy 1>a≥0.8, so that the oil fume and water vapor flowing along the smoke baffle 1 will all pass through the deflector 21, and the deflector 21 can prevent smoke from leaking out of the first gap 12.

[0062] In some embodiments, the thickness of the backing plate 2 is less than or equal to 1.5 mm, the backing plate 2 only needs to guide the oil fume and water vapor to be discharged smoothly, the backing plate 2 does not need to support other parts, and the mass of the oil fume and water vapor is lighter, so that the structural strength requirement of the backing plate 2 is not high, the thickness of the backing plate 2 can be designed to be less than or equal to 1.5 mm, the material of the backing plate 2 can be reduced, and the manufacturing cost can be reduced.

[0063] The same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components; in the description of the present application, it should be understood that if the orientations or positional relationships indicated by the terms “upper”, “lower”, “left”, “right” and the like are based on the orientations or positional relationships shown in the drawings, they are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationship in the drawings are only used for exemplary illustration, and cannot be understood as a limitation of the present patent, for those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.
