Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of kitchen utensils, in particular to a combined kitchen utensil and an integrated cooking device. BACKGROUND
[0002] In modern kitchens, kitchen utensils with different functions are usually assembled together to form a combined kitchen utensil with compact structure, so as to reduce the kitchen space occupied by the kitchen utensils. At present, there are combined kitchen utensils on the market which combine a cooking device with a steaming function (for example, a steaming oven or a steaming oven) and a range hood. The cooking device with a steaming function has an inner container and an exhaust pipe, and the exhaust pipe is used to exhaust the gas (including high-temperature steam and oil fume) in the inner container. The range hood has an air duct, and when the range hood is working, the oil fume in the kitchen is exhausted to the outside through the air duct. The exhaust pipe and the air duct are communicated, so that the gas exhausted from the inner container can flow to the outside through the air duct, which can prevent the high-temperature steam exhausted by the cooking device with a steaming function from hurting the user or polluting the indoor environment.
[0003] However, in the traditional combined kitchen utensil which combines a cooking device with a steaming function and a range hood, the flow direction of the gas in the inner container when entering the air duct is almost perpendicular to the flow direction of the oil fume in the kitchen when entering the air duct, in other words, the gas from the inner container entering the air duct through the exhaust pipe hinders the flow of the oil fume from the kitchen into the air duct to some extent, which reduces the effect of the range hood on quickly exhausting oil fume. CONTENT OF THE UTILITY MODEL
[0004] Therefore, it is necessary to provide a combined kitchen utensil and an integrated cooking device in view of the above problems.
[0005] In order to solve the above problems, the technical solutions of the present application are as follows:

[0009] The combined kitchen utensil has at least the following beneficial effects:
[0010] For the combination kitchen utensil, when the range hood and the cooking equipment with the steaming function work simultaneously, the gas in the inner container is sequentially discharged into the air duct through the first pipe section and the second pipe section. Since the outlet of the second pipe section is directed obliquely upward, the flow direction of the gas discharged from the inner container into the air duct is along the obliquely upward direction, and the oil fume sucked by the range hood flows upward in the air duct. Therefore, the flow direction of the gas discharged from the inner container is basically consistent with the flow direction of the oil fume entering the air duct, and the gas flow formed by the gas discharged from the inner container helps the upward flow of the oil fume in the air duct, which is beneficial to improve the effect of the range hood on quickly sucking the oil fume.
[0011] In one of the embodiments, the second pipe section is linear, and the second pipe section extends along the obliquely upward direction.
[0012] In this way, the gas discharged from the inner container always flows along the obliquely upward direction in the second pipe section, which is beneficial to improve the speed of the gas flow formed by the gas discharged from the inner container when leaving the outlet of the second pipe section, to improve the help of the gas flow formed by the gas discharged from the inner container to the upward flow of the oil fume in the air duct, and to improve the effect of the range hood on quickly sucking the oil fume.
[0013] In one of the embodiments, the exhaust pipe further comprises a circular arc pipe section, and the first pipe section and the second pipe section are circularly arc transitioned through the circular arc pipe section.
[0014] In this way, the gas flow formed by the gas discharged from the inner container can be smoothly turned during the process of entering the second pipe section from the first pipe section, which can reduce the kinetic energy loss of the gas flow formed by the gas discharged from the inner container in the exhaust pipe, is beneficial to improve the speed of the gas flow formed by the gas discharged from the inner container when leaving the outlet of the second pipe section, to improve the help of the gas flow formed by the gas discharged from the inner container to the upward flow of the oil fume in the air duct, and to improve the effect of the range hood on quickly sucking the oil fume.
[0015] In one of the embodiments, the central angle of the circular arc pipe section is α, and α satisfies: α < 90°.
[0016] In this way, the speed of the gas flow formed by the gas discharged from the inner container when leaving the outlet of the second pipe section is improved, the help of the gas flow formed by the gas discharged from the inner container to the upward flow of the oil fume in the air duct is improved, and the effect of the range hood on quickly sucking the oil fume is improved.
[0017] In one of the embodiments, the end of the exhaust pipe relatively far away from the air duct is located above the end of the exhaust pipe relatively close to the air duct.
[0018] In this way, it can be prevented that impurities from the outside easily enter the inner container through the exhaust pipe, which is beneficial to prevent the inner container from being contaminated.
[0019] In one of the embodiments, the range hood comprises a rear shell and a partition plate, the rear shell and the partition plate form the air duct; the partition plate is located between the inner container and the rear shell to separate the back side of the inner container from the air duct.
[0020] In this way, the inner container is protected.
[0021] In one of the embodiments, the partition plate comprises a first inclined section, a vertical section and a second inclined section, which are sequentially connected from bottom to top; the first inclined section and the rear shell form a converging channel, the cross-sectional area of the converging channel gradually decreases along the direction from bottom to top; the vertical section and the rear shell form an equal-width channel, the cross-sectional area of the equal-width channel is constant along the direction from bottom to top; the second inclined section and the rear shell form a diverging channel, the cross-sectional area of the diverging channel gradually increases along the direction from bottom to top; the back side of the inner container is contoured with the partition plate.
[0022] In this way, the size of the part of the inner container corresponding to the vertical section can be increased, so that the part of the inner container corresponding to the vertical section can accommodate a larger container to place more food, thereby improving the cooking efficiency of the cooking device with the steaming function.
[0023] In one of the embodiments, the outlet of the second pipe section is located directly below the first inclined section.
[0024] In this way, the liquid (such as oil and condensate) formed at the upper part of the air duct can be prevented from dripping into the exhaust pipe.
[0025] In one of the embodiments, the cooking device is connected to the range hood in a liftable manner, and the partition plate is fixedly connected to the inner container.
[0026] In this way, when it is necessary to put food into the cooking device or take out the food in the cooking device, the cooking device can be lowered to facilitate the user to put or take out the food. When it is necessary to cook food by means of the cooktop, the cooking device can be raised to increase the space between the cooktop and the combination kitchen appliance, thereby facilitating the user to cook food on the cooktop.
[0027] The application also provides an integrated cooking device, which comprises:
[0028] a cooktop; and
[0029] The combination kitchen appliance described above is located directly above the cooktop.
[0030] The integrated cooking device has at least the following beneficial effects:
[0031] For the integrated cooking device, when the range hood and the cooking device with the steaming function work simultaneously, the gas in the inner container is discharged into the air duct through the first pipe section and the second pipe section in turn. Since the outlet of the second pipe section is directed obliquely upward, the flow direction of the gas discharged from the inner container into the air duct is along the obliquely upward direction, and the oil fume sucked by the range hood flows upward in the air duct. Therefore, the flow direction of the gas discharged from the inner container into the air duct is basically consistent with the flow direction of the oil fume into the air duct, the airflow formed by the gas discharged from the inner container helps the upward flow of the oil fume in the air duct, and the effect of the range hood on quickly sucking the oil fume is improved.

[0045] Referring to Figures 1 to 5 The present application provides a combination kitchen appliance, which comprises an extractor hood 1 and a cooking device 2 with a steaming function. The extractor hood 1 has an air duct 11 extending upwardly from bottom to top and a fan 12 for guiding the gas in the air duct 11 to flow upwardly from bottom to top. In this way, during the operation of the extractor hood 1, the oil fume sucked by the extractor hood 1 flows upwardly in the air duct 11. The cooking device 2 with a steaming function is arranged on the extractor hood 1, and the cooking device 2 has an inner container 21 and an exhaust pipe 22. The exhaust pipe 22 comprises a first pipe section 221 and a second pipe section 222. The first pipe section 221 is arranged in the inner container 21 and is arranged obliquely downwardly. The second pipe section 222 is fixedly connected to the first pipe section 221, and the outlet of the second pipe section 222 is located in the air duct 11 and faces obliquely upwardly.
[0046] For the combination kitchen appliance, when the extractor hood 1 and the cooking device 2 with a steaming function operate simultaneously, the gas in the inner container 21 flows into the air duct 11 through the first pipe section 221 and the second pipe section 222 in sequence. Since the outlet of the second pipe section 222 faces obliquely upwardly, the gas flowing out of the inner container 21 flows along the obliquely upwardly direction when it enters the air duct 11. Since the oil fume sucked by the extractor hood 1 flows upwardly in the air duct 11, the flow direction of the gas flowing out of the inner container 21 is basically consistent with the flow direction of the oil fume entering the air duct 11. The gas flow formed by the gas flowing out of the inner container 21 helps the oil fume to flow upwardly in the air duct 11, which is beneficial to improve the effect of the extractor hood 1 to quickly extract the oil fume.
[0047] Exemplarily, the cooking device 2 with a steaming function is a steaming oven or a steaming oven.
[0048] Referring to Figure 5 Exemplarily, the second pipe section 222 is linear, and the second pipe section 222 extends along the obliquely upwardly direction. In this way, the gas flowing out of the inner container 21 always flows along the obliquely upwardly direction in the second pipe section 222, which is beneficial to improve the speed of the gas flow formed by the gas flowing out of the inner container 21 when it leaves the outlet of the second pipe section 222. This is beneficial to improve the effect of the gas flow formed by the gas flowing out of the inner container 21 to help the oil fume to flow upwardly in the air duct 11, which is beneficial to improve the effect of the extractor hood 1 to quickly extract the oil fume.
[0049] Referring to Figure 5 The exhaust pipe 22 further comprises a circular-arc pipe section 223, and the first pipe section 221 and the second pipe section 222 are connected through the circular-arc pipe section 223. In this way, the gas flow formed by the gas exhausted from the inner container 21 can be smoothly turned when entering the second pipe section 222 from the first pipe section 221, and the kinetic energy loss of the gas flow formed by the gas exhausted from the inner container 21 in the exhaust pipe 22 can be reduced, which is beneficial to increase the speed of the gas flow formed by the gas exhausted from the inner container 21 when leaving the outlet of the second pipe section 222, and is beneficial to increase the effect of the gas flow formed by the gas exhausted from the inner container 21 on the upward flow of the oil fume in the air duct 11, and is beneficial to improve the effect of the extractor 1 on quickly extracting the oil fume.
[0050] The central angle of the circular-arc pipe section 223 is α, and preferably, α satisfies: α < 90°. This is beneficial to increase the speed of the gas flow formed by the gas exhausted from the inner container 21 when leaving the outlet of the second pipe section 222, and is beneficial to increase the effect of the gas flow formed by the gas exhausted from the inner container 21 on the upward flow of the oil fume in the air duct 11, and is beneficial to improve the effect of the extractor 1 on quickly extracting the oil fume.
[0051] Referring to Figure 5 The end of the exhaust pipe 22 far away from the air duct 11 is located above the end of the exhaust pipe 22 close to the air duct 11. This can prevent impurities from the outside easily entering the inner container 21 through the exhaust pipe 22, and is beneficial to prevent the inner container 21 from being contaminated.
[0052] Referring to Figures 2 to 4 The extractor 1 comprises the rear shell 13 and the partition plate 14, and the rear shell 13 and the partition plate 14 surround to form the air duct 11. The partition plate 14 is located between the inner container 21 and the rear shell 13 to separate the back side of the inner container 21 from the air duct 11. This is beneficial to protect the inner container 21.
[0053] Referring to Figure 4The partition plate 14 comprises a first inclined section 141, a vertical section 142 and a second inclined section 143, which are sequentially connected from bottom to top; the first inclined section 141 and the rear shell 13 surround to form a converging passage 111, and the cross-sectional area of the converging passage 111 gradually decreases along the direction from bottom to top; the vertical section 142 and the rear shell 13 surround to form an equal-width passage 112, and the cross-sectional area of the equal-width passage 112 is constant along the direction from bottom to top; the second inclined section 143 and the rear shell 13 surround to form a diverging passage 113, and the cross-sectional area of the diverging passage 113 gradually increases along the direction from bottom to top; the back side of the inner container 21 is conformally arranged with the partition plate 14. In this way, the size of the part of the inner container 21 corresponding to the vertical section 142 can be increased, so that the part of the inner container 21 corresponding to the vertical section 142 can accommodate a larger container to place more food, thereby improving the cooking efficiency of the cooking device 2 with the steaming function.
[0054] Preferably, the outlet of the second pipe section 222 is located directly below the first inclined section 141. In this way, liquid (such as oil liquid and condensed water) formed on the upper part of the air duct 11 can be prevented from dripping into the exhaust pipe 22.
[0055] The range hood 1 is usually located at a high position in the kitchen, which causes the cooking device 2 with the steaming function installed on the range hood 1 to also be located at a high position. Preferably, the cooking device 2 is connected to the range hood 1 in a liftable manner, and the partition plate 14 is fixedly connected to the inner container 21. In this way, when food needs to be put into the cooking device 2 or taken out of the cooking device 2, the cooking device 2 can be lowered down to facilitate the user to put or take out the food. When food needs to be cooked by means of the cooktop (which can be understood as being located below the range hood 1), the cooking device 2 can be raised up to increase the space between the cooktop and the combination kitchen appliance, thereby facilitating the user to cook food on the cooktop.
[0056] In some embodiments, a sliding rail is arranged on one of the cooking device 2 and the range hood 1, and a sliding block is arranged on the other one, and the cooking device 2 and the range hood 1 are connected in a liftable manner through the sliding block and the sliding rail. In other embodiments, a sliding groove is arranged on one of the cooking device 2 and the range hood 1, and a sliding seat is arranged on the other one, and the cooking device 2 and the range hood 1 are connected in a liftable manner through the sliding groove and the sliding seat.
[0057] Exemplarily, the lifting movement of the cooking device 2 relative to the range hood 1 is powered by a motor.
[0058] In some embodiments, the cooking device 2 and the range hood 1 are connected in a liftable manner through a linear module.
[0059] The application further provides a combination kitchen appliance, which comprises a cooktop and the above-mentioned cooking device 2, and the cooking device 2 is located directly above the cooktop.
[0060] For the integrated cooking device, when the range hood 1 and the cooking device 2 with the steaming function work simultaneously, the gas in the inner container 21 is sequentially discharged into the air duct 11 through the first pipe section 221 and the second pipe section 222. Since the outlet of the second pipe section 222 is directed obliquely upward, the flow direction of the gas discharged from the inner container 21 into the air duct 11 is along the oblique upward direction. Since the oil fume sucked by the range hood 1 flows upward in the air duct 11, the flow direction of the gas discharged from the inner container 21 into the air duct 11 is basically consistent with the flow direction of the oil fume into the air duct 11. The gas flow formed by the gas discharged from the inner container 21 helps the upward flow of the oil fume in the air duct 11, which is beneficial to improve the effect of the range hood 1 on quickly sucking the oil fume.
[0061] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not contradict each other, they should be considered as the scope of the present disclosure.
[0062] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the protection scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
