[0034] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the advantages of saving space, good fume extraction effect, energy saving, low consumption and environmental protection. Figure 7 The integrated stove includes a frame 310, a gas stove 320, and a smoke exhaust mechanism 330. The gas stove 320 is arranged on the upper end surface of the frame 310, and the smoke exhaust mechanism 330 is located on the side of the gas stove 320. The fan of the smoke exhaust mechanism 330 is arranged inside the frame 310. The smoke exhaust mechanism 330 is provided with a smoke exhaust port 331 facing the gas stove 320. The smoke exhaust mechanism 330 has a flip-open cover plate 332 that can close or open the smoke exhaust port 331. When cooking, the fan starts, and the cover plate 332 rotates to open the smoke exhaust port 331, sucking away cooking fumes. After cooking is completed, the cover plate 332 rotates to close the smoke exhaust port 331. To cover the smoke exhaust port 331 and improve aesthetics, the cover plate 332 has a substantially identical shape to the smoke exhaust port 331, and can cover the smoke exhaust port 331. In the closed state, when the user cleans the oil stains on the outer surface of the cover plate 332, the oil stains and cleaning water will flow down along the cover plate 332 and the smoke exhaust mechanism 330 to the stove where the gas stove 320 is located, resulting in a large cleaning range, a lot of time, and a poor user experience.

[0037] For this purpose, refer to Figures 1 to 3 The embodiment of the first aspect of the present invention provides a smoke exhaust component 100, which can prevent oil and water from flowing along the smoke exhaust component to the stove 200 during cleaning, making it easier for users to clean and improving user experience.

[0038] The smoke exhaust assembly 100 includes a housing 110 and an opening and closing plate 120. An air duct 101 is formed inside the housing 110 for the flow of oil smoke. One side of the housing 110 is a panel 111, which is typically arranged vertically. A smoke outlet 112 is provided at the top of the panel 111. The smoke outlet 112 is connected to the air duct 101. The smoke is drawn into the air duct 101 through the smoke outlet 112 by the suction effect of the fan and then exhausted. Considering that integrated stoves typically have two burners spaced apart, the smoke outlet 112 can be arranged in a strip corresponding to the two burners, or it can be configured as two long windows to achieve the purpose of drawing away the oil smoke.

[0039] When the machine is not in use, the inhalation port 112 needs to be closed. Therefore, an opening and closing plate 120 is connected to the housing 110. The opening and closing plate 120 is similar in shape to the inhalation port 112 and is located within the inhalation port 112, thereby covering most of the inhalation port 112 and thus closing it. At the same time, to allow the inhalation port 112 to be opened, the upper end of the opening and closing plate 120 is hinged to the housing 110, allowing the opening and closing plate 120 to rotate. The rotation of the opening and closing plate 120 allows the opening and closing of the inhalation port 112 to be opened and closed.

[0040] Taking into account that after the integrated stove has been used for a period of time, oil will condense on the outer surface of the opening and closing plate 120 (the side facing away from the air duct 101), the outer surface of the opening and closing plate 120 needs to be cleaned. In order to prevent the cleaning water and oil from flowing onto the channel panel 111, the opening and closing plate 120 is connected to a lining plate 130. The lower end of the lining plate 130 is provided with an inclined guide portion 131. The guide portion 131 extends from the lower end of the opening and closing plate 120 into the air duct. Since the guide portion 131 is inclined, the cleaning water and oil flow along the guide portion 131 to the inside of the air duct 101, and then drip into the oil collection box in the air duct 101, which is convenient for users to clean in a centralized manner.

[0041] The smoke exhaust assembly 100 of the first embodiment of the present invention is connected to the lining plate 130 on the opening and closing plate 120, and an inclined guide portion 131 is provided at the lower end of the lining plate 130. The guide portion 131 extends from the lower end of the opening and closing plate 120 to the air duct 101. When the opening and closing plate 120 is closed, when the user cleans the oil stains on the outer surface of the opening and closing plate 120, the oil stains and water first flow downward along the opening and closing plate 120. When reaching the lower end of the opening and closing plate 120, they will flow along the inclined guide portion 131 to the air duct 101, and finally drip into the oil collecting box in the air duct 101, and will not drip from the lower end of the opening and closing plate 120 to the panel 111, thereby preventing oil stains and water from flowing along the panel 111 to the stove, avoiding expanding the user's cleaning range, reducing the cleaning workload, and improving the user experience.

[0042] It is understandable that the opening and closing plate 120 can be rotated inwardly to the inside of the air duct 101 to open the smoke outlet 112. Since the fan is located below the air duct 101, the inclined opening and closing plate 120 helps to guide the oil smoke. However, the inner surface of the opening and closing plate 120 and the inner wall of the air duct 101 folded by the opening and closing plate 120 are difficult to clean. The user can only clean them by disassembling the opening and closing plate 120, which is difficult to operate and has a poor user experience. The opening and closing plate 120 can also be rotated outwardly to open the smoke outlet 112. In order to gather the oil smoke, the opening and closing plate 120 is usually tilted downward. This means that when cleaning the inner surface of the opening and closing plate 120, the user can only bend down and wipe it, which is easy to get tired and has a poor user experience.

[0043] In the smoke exhaust assembly 100 according to the first embodiment of the present invention, the opening and closing plate 120 has a cleaning state, in which the opening and closing plate 120 rotates away from the air duct 101 to the top of the inhalation port 112. Figure 3 As shown, when the user plans to clean the inner surface of the opening and closing plate 120, the opening and closing plate 120 is switched to the cleaning state. At this time, the opening and closing plate 120 is rotated above the smoking port 112. The inner surface of the opening and closing plate 120 is at a high position and away from the housing 110. The user can conveniently wipe the inner surface of the opening and closing plate 120 with a wet cloth. The user does not need to bend down and can clean the inner surface of the opening and closing plate 120 in a comfortable state, which greatly improves the user experience. In addition, because the opening and closing plate 120 is away from the air duct 101 and the opening and closing plate 120 is rotated above the smoking port 112, it is convenient for the user to wipe the inner wall of the air duct 101, especially the part of the inner wall facing the opening and closing plate 120, which brings convenience to the user.

[0044] It is understood that during operation of the smoke exhaust assembly 100, the opening and closing plate 120 will not rotate to the cleaning state. Therefore, the opening and closing plate 120 can be manually operated to switch to the cleaning state. For example, an electrically controlled drive component can be provided on the housing 100, and the drive component can drive the opening and closing plate 120 to rotate to open the smoke outlet 112. When cleaning is required, the opening and closing plate 120 is separated from the drive component and manually adjusted. A clutch can be used to connect and disconnect the drive component and the opening and closing plate 120. Of course, the opening and closing plate 120 can also be driven by the drive component to rotate to the cleaning state, which can be set in the integrated stove's control program.

[0045] Reference Figure 3It is understood that, in the cleaning state, the angle between the opening and closing plate 120 and the panel 111 is greater than 90 degrees, wherein the angle between the opening and closing plate 120 and the panel 111 is preferably 120 degrees to 160 degrees. The opening and closing plate 120 is in an upwardly inclined state, and the user can directly observe the inner surface of the opening and closing plate 120, and can simply raise the hand to wipe the inner surface of the opening and closing plate 120, which is convenient for operation. In addition, a positioning block can be provided at the upper end of the housing 110. When the opening and closing plate 120 is in the cleaning state, the opening and closing plate 120 abuts against the positioning block, and the positioning block provides a supporting force. When the user wipes the inner surface of the opening and closing plate 120, the opening and closing plate 120 is prevented from rotating, thereby avoiding damage to the opening and closing plate 120 and improving the reliability of use.

[0046] Reference Figures 4 to 6 In some embodiments, a smoke collecting portion 140 is provided at the upper end of the housing 110. The smoke collecting portion 140 extends in a direction away from the air duct 101. The function of the smoke collecting portion 140 is to block and collect the rising oil smoke so as to absorb the oil smoke from the smoke outlet 112. The smoke collecting portion 140 usually has an inclined surface facing the stove 200. The inclined surface is a smooth plane to facilitate the guidance of the oil smoke and facilitate the flow of the oil smoke to the smoke outlet 112. Figure 6 As shown, in the cleaning state, the opening and closing plate 120 abuts against the smoke collecting portion 140, and the smoke collecting portion 140 is used as a limiting support structure of the opening and closing plate 120. The smoke collecting portion 140 provides a supporting force to prevent the opening and closing plate 120 from rotating when the user wipes the inner surface of the opening and closing plate 120, thereby avoiding damage to the opening and closing plate 120 and improving reliability of use.

[0047] It should be understood that a locking mechanism can be provided on the smoke collecting portion 140 to secure the opening and closing plate 120 so that the opening and closing plate 120 remains in a clean state. This is particularly useful for manually operated opening and closing plates 120, as it facilitates the user in cleaning the interior of the air duct 101. The locking mechanism can be in the form of a snap or magnetic structure, as long as it can secure the opening and closing plate 120 in a clean state and prevent it from falling.

[0048] Reference Figure 4 and Figure 5, considering that after the integrated stove has been used for a period of time, oil will condense on the outer surface of the opening and closing plate 120 (the side away from the air duct 101), the outer surface of the opening and closing plate 120 needs to be cleaned. In order to prevent the cleaning water and oil from flowing onto the channel panel 111, the opening and closing plate 120 is connected to the lining plate 130. The lower end of the lining plate 130 is provided with an inclined guide part 131. The guide part 131 extends from the lower end of the opening and closing plate 120 into the air duct. Since the guide part 131 is arranged at an angle, the cleaning water and oil flow along the guide part 131 to the inside of the air duct 101, and then drip into the oil collection box in the air duct 101, which is convenient for users to clean in a centralized manner. When the user cleans the oil stains on the outer surface of the opening and closing plate 120, the oil stains and water first flow downward along the opening and closing plate 120. When reaching the lower end of the opening and closing plate 120, they will flow along the inclined guide part 131 into the air duct 101, and finally drip into the oil collecting box in the air duct 101, but will not drip from the lower end of the opening and closing plate 120 to the panel 111, preventing the oil stains and water from flowing along the panel 111 to the stove, avoiding expanding the user's cleaning range, reducing the cleaning workload, and improving the user experience.

[0049] It is understandable that, referring to Figures 1 to 3 The upper end of the opening and closing plate 120 is connected to the housing 110 via a hinge 150. The hinge 150 serves as a rotation support, which can not only realize the rotation of the opening and closing plate 120, but also limit the position of the opening and closing plate 120. In order to improve the aesthetics of the integrated stove, the hinge 150 is usually installed on the inner surface of the opening and closing plate 120, that is, the hinge 150 is located in the air duct 101, and the opening and closing plate 120 is used to cover the hinge 150. In order to allow the opening and closing plate 120 to rotate to a cleaning state, an avoidance groove is provided on the housing 110 above the smoking port 112. The avoidance groove is used to accommodate the opening and closing plate 120 to prevent interference and minimize the gap between the opening and closing plate 120 and the housing 110.

[0050] It is understandable that the guide portion 131 can be a straight plate or a curved plate. Figure 2The guide portion 131 includes a first guide plate 1311 and a second guide plate 1312 that are connected to each other. The two sides of the second guide plate 1312 are respectively connected to the first guide plate 1311 and the lining plate 130. Moreover, the angle between the first guide plate 1311 and the panel 111 is smaller than the angle between the second guide plate 1312 and the panel 111, that is, the first guide plate 1311 is biased towards the vertical direction, and the second guide plate 1312 is biased towards the horizontal direction. With the above structure, when cleaning the outer surface of the opening and closing plate 120, the oil and water first flow downward along the opening and closing plate 120. When reaching the lower end of the opening and closing plate 120, they turn to flow along the second guide plate 1312 and the first guide plate 1311 to the inside of the air duct 101. At this time, the second guide plate 1312, which is biased towards the horizontal direction, guides the oil and water to quickly enter the air duct 101 and quickly move away from the panel 111, while the first guide plate 1311, which is biased towards the vertical direction, is conducive to the oil and water dripping downward and gathering in the oil collecting box.

[0051] Reference Figure 1 It is understandable that the lining plate 130 covers the side of the opening and closing plate 120 facing the air duct 101. The opening and closing plate 120 is usually a glass plate with a smooth surface and good decorative effect. However, the glass plate is difficult to operate when connected to the hinge 150, and the glass plate is easily broken. The lining plate 130 is made of a metal plate. The lining plate 130 covers the opening and closing plate 120, which can increase the structural strength and make the connection between the lining plate 130 and the hinge 150 easier and more stable. The lining plate 130 and the opening and closing plate 120 have a large contact area and can be bonded with glue. The connection between the lining plate 130 and the second guide plate 1312 is set to a smooth transition curved surface, which is conducive to the flow of oil and water. The connection between the first guide plate 1311 and the second guide plate 1312 is also set to a smooth transition curved surface, which reduces flow resistance, is conducive to the flow of oil and water, and can reduce the adhesion of oil to the connection between the first guide plate 1311 and the second guide plate 1312.

[0052] It can be understood that the lining 130 is a sheet metal part, and the lining 130 and the guide part 131 are an integral structural part. The lower end of the lining 130 is formed into a first guide plate 1311 and a second guide plate 1312 through a bending process. The processing is simple and the cost is low. It can improve the consistency of the product and simplify the assembly process. It is only necessary to glue the lining 130 and the opening and closing plate 120 together.

[0053] Reference Figure 1 and Figure 2It is understood that when the opening and closing plate 120 closes the smoking port 112, a first gap is reserved between the opening and closing plate 120 and the panel 111. The purpose of reserving the first gap is to increase the distance between the opening and closing plate 120 and the panel 111. When the user cleans the oil stains on the outer surface of the opening and closing plate 120, the oil stains and water first flow downward along the opening and closing plate 120. When reaching the lower end of the opening and closing plate 120, due to the presence of the first gap, the oil stains and water do not contact the panel 111, but are diverted to the guide portion 131 and then directed into the interior of the air duct 101. It should be understood that the height of the first gap is H. A larger value of H is more conducive to preventing oil stains and water from contacting the panel 111. However, a larger value of H will affect the opening and closing plate 120 from closing the smoking port 112. Therefore, a compromise is required to select the value of H. It can be understood that, considering that the diameter of oil and water droplets is less than 5 mm, the height H of the first gap is set to be greater than or equal to 5 mm, among which 5.5 mm is the best solution, which can meet the needs of droplets passing through, while the first gap is controlled within a smaller range.

[0054] It can be understood that the minimum distance between the panel 111 and the guide portion 131 is also greater than or equal to 5 mm, that is, the minimum distance between the first guide plate 1311 and the panel 111 is greater than or equal to 5 mm, so that the droplets dripping from the first guide plate 1311 will not contact the panel 111, and there is sufficient distance.

[0055] The integrated stove provided in the second embodiment of the present invention includes the exhaust assembly 100 of the first embodiment. The exhaust assembly 100 includes a housing 110 and an opening and closing plate 120. An air duct 101 is formed inside the housing 110 for the flow of oil smoke. One side of the housing 110 is a panel 111. Typically, the panel 111 is arranged vertically. A smoke outlet 112 is provided at the upper portion of the panel 111. The smoke outlet 112 is connected to the air duct 101. The smoke outlet 112 is sucked into the air duct 101 through the suction effect of the fan and then exhausted. Considering that the integrated stove usually has two burners, and the two burners are spaced apart, the smoke outlet 112 can be arranged in a long strip corresponding to the two burners, or the smoke outlet 112 can be set as two long windows to achieve the purpose of sucking away the oil smoke.

[0056] When the machine is not in use, the inhalation port 112 needs to be closed. Therefore, an opening and closing plate 120 is connected to the housing 110. The opening and closing plate 120 is similar in shape to the inhalation port 112 and is located within the inhalation port 112, thereby covering most of the inhalation port 112 and thus closing it. At the same time, to allow the inhalation port 112 to be opened, the upper end of the opening and closing plate 120 is hinged to the housing 110, allowing the opening and closing plate 120 to rotate. The rotation of the opening and closing plate 120 allows the opening and closing of the inhalation port 112 to be opened and closed.

[0057] Taking into account that after the integrated stove has been used for a period of time, oil and dirt will condense on the outer surface of the opening and closing plate 120 (the side facing away from the air duct 101), the outer surface of the opening and closing plate 120 needs to be cleaned. In order to prevent the cleaning water and oil from flowing onto the channel panel 111, the opening and closing plate 120 is connected to a lining plate 130, and the lower end of the lining plate 130 is provided with an inclined guide portion 131, which extends from the lower end of the opening and closing plate 120 into the air duct.

[0058] The smoke exhaust assembly 100 of the first embodiment of the present invention is connected to the lining plate 130 on the opening and closing plate 120, and an inclined guide portion 131 is provided at the lower end of the lining plate 130. The guide portion 131 extends from the lower end of the opening and closing plate 120 to the air duct 101. When the opening and closing plate 120 is closed, when the user cleans the oil stains on the outer surface of the opening and closing plate 120, the oil stains and water first flow downward along the opening and closing plate 120. When reaching the lower end of the opening and closing plate 120, they will flow along the inclined guide portion 131 to the air duct 101, and finally drip into the oil collecting box in the air duct 101, and will not drip from the lower end of the opening and closing plate 120 to the panel 111, thereby preventing oil stains and water from flowing along the panel 111 to the stove, avoiding expanding the user's cleaning range, reducing the cleaning workload, and improving the user experience.

[0059] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
