[0035] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0036] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0037] like Figures 1 to 4 The integrated range hood according to the embodiment of the invention includes: a range hood body 1, a fan assembly 2 and a cooking device body 3.

[0038] A smoke collecting chamber is provided inside the range hood body 1 , and the smoke collecting chamber is provided with a smoke inlet 14 and a smoke exhaust port 13 . The smoke inlet 14 is provided at the bottom of the range hood body 1 , and the smoke exhaust port 13 is provided at the middle of the top of the range hood body 1 .

[0039] Specifically, the smoke inlet 14 is arranged near the lower part of the smoke collecting chamber, and the smoke exhaust port 13 is arranged at the top of the smoke collecting chamber.

[0040] The range hood body 1 can be any range hood body 1 in the prior art. The specific components and installation methods of the components are all in the prior art and will not be described in detail here.

[0041] The fan assembly 2 is disposed within the smoke collecting chamber and adjacent to the smoke exhaust port 13 to provide suction, drawing the fumes from the smoke outlet 14 into the smoke collecting chamber and then exhausting the fumes through the smoke exhaust port 13. The fan assembly 2 can be any conventional fan assembly 2. The specific components and mounting methods of the components are conventional and will not be further described here.

[0042] The cooking device body 3 is fixedly mounted within the smoke collection chamber, near the center of the bottom of the range hood body 1. At least two sides of the smoke collection chamber are left unoccupied, forming a flue 4 between two opposing sides of the cooking device body 3 and the range hood body 1. The flue 4 communicates with a smoke inlet 14 and a smoke exhaust port 13, respectively. When the range hood is in operation, cooking fumes enter the smoke collection chamber through the smoke inlet 14 and are then exhausted through the smoke exhaust port 13.

[0043] Since the flues 4 are arranged on two opposite sides of the cooking device body 3, the range hood can be called a dual-duct integrated range hood.

[0044] In this embodiment, the cooking device can be an oven, a microwave oven, a steamer, or a steam-oven combination. The cooking device body 3 is an oven body, a microwave oven body, a steamer body, or a steam-oven combination body. In the following embodiment, the cooking device is a steam-oven combination as an example for specific description.

[0045] In a preferred embodiment, the flue 4 includes a bottom flue 42 and a side flue 41; the bottom flue 42 is formed between the bottom of the cooking device body 3 and the bottom plate 111 of the range hood body 1; the side of the cooking device body 3 and the side plate 112 of the range hood body 1 form the side flue 41.

[0046] Specifically, the range hood body 1 includes an outer cover assembly 11 and an electronic control assembly 12. The outer cover assembly 11 comprises a bottom plate 111, side panels 112, an outer rear panel 113, and an outer front panel 114. The upper portion of the side panels 112 is tilted, converging the flue 4 from bottom to top, converging the smoke close to the fan assembly 2 to improve exhaust efficiency.

[0047] In a preferred embodiment, the base plate 111 is tilted downward from front to back, that is, the front end of the base plate 111 (the end close to the operator) is higher than the rear end of the base plate 111 (the end close to the wall after installation).

[0048] When installing the cooking device body 3, the front end of the bottom of the cooking device body 3 is tightly fitted with the front end of the bottom plate 111 of the range hood body 1. Since the bottom of the cooking device body 3 is a flat structure, the rear end of the bottom of the cooking device body 3 is spaced apart from the rear end of the bottom plate 111 of the range hood body 1 to form a bottom flue 42. Figure 3 It can be seen that the bottom flue 42 is triangular in side view.

[0049] Specifically, the inclination angle of the bottom plate 111 is 12° to 15°.

[0050] The above technical solution has demonstrated significant benefits in many aspects in the design of integrating the functions of steam oven and range hood:

[0051] First of all, from the perspective of space optimization, by cleverly embedding the steam oven body into the range hood body 1, an integrated design of kitchen equipment is achieved, which greatly saves kitchen space. Especially for small kitchens with limited space, this compact design can improve space utilization and make the overall layout more simple and orderly.

[0052] Secondly, the tight fit design between the steam oven body and the front end of the bottom plate 111 of the range hood body 1 ensures good sealing at the connection between the two, preventing oil smoke from leaking from the smoke collecting chamber, thereby improving overall work efficiency and safety, and is also beneficial to the cleaning and maintenance of the equipment.

[0053] Furthermore, this design makes the main body of the steam oven positioned lower, so that users do not need to raise their arms significantly when operating the steam oven, which greatly improves the convenience and comfort of use. It is especially friendly to shorter users and fully reflects the humanized design concept.

[0054] Furthermore, the main steam oven is designed at the bottom of the smoke collection chamber, leaving ample space at the top to maintain effective smoke extraction. This allows for the rapid and efficient removal of cooking fumes, effectively reducing air pollution and improving the kitchen environment. This also extends the lifespan of the steam oven and range hood.

[0055] To sum up, this technical solution has multiple advantages such as space optimization, seamless connection, humanized operation and efficient smoke exhaust. It not only meets the modern family's demand for multi-functional and high-efficiency kitchen appliances, but also takes into account the user experience and health and environmental protection concepts. It has high practical value and market promotion prospects.

[0056] In a preferred embodiment, two side flues 41 are respectively formed between the two sides of the cooking device body 3 and the two sides of the range hood body 1 .

[0057] In another embodiment, the cooking device is a steam-oven combination, comprising a cavity assembly 31, a door assembly 32, a heating assembly 33, and a thermal insulation assembly 34. Cavity assembly 31 comprises a cavity front panel 311, a cavity interior 312, and a cavity rear panel 313; door assembly 32 comprises a door hinge, door frame, door glass, and door seal; and thermal insulation assembly 34 comprises thermal insulation and thermal insulation panels. Cavity interior 312 is a cooking area with a volume of 30 to 70 liters.

[0058] The steam oven is a modern kitchen appliance that integrates the dual functions of steaming and baking. Its sophisticated and complex mechanism is designed to achieve efficient and energy-saving cooking and good heat preservation effect.

[0059] Cavity assembly 31: It is the core part of the steam oven, mainly including the cavity front panel 311, the cavity inner tank 312 and the cavity rear panel 313. The cavity front panel 311 is usually made of high-temperature resistant and corrosion-resistant materials. It serves as the front appearance display of the equipment and also plays a protective role. The cavity inner tank 312 is the space where cooking is actually carried out. The material is generally made of stainless steel or other food-grade materials with good thermal conductivity and easy to clean. The surface is specially treated to withstand high-temperature baking and steam cooking. The cavity rear panel 313 is mainly responsible for sealing the entire cavity, and usually also has a certain heat insulation effect to prevent excessive heat loss.

[0060] Door assembly 32: Door assembly 32 is secured to the oven cavity via hinges, allowing for easy opening and closing. The door frame plays a key role in stabilizing the door and ensuring a tight seal. The door glass is typically double-layered tempered glass, offering high transparency, allowing users to visually observe the food during cooking. It also provides excellent insulation to prevent heat from escaping and potentially burning the user. The door seal is a key component in ensuring the oven's tightness. Made of high-temperature-resistant, resilient material, it effectively prevents steam and heat from escaping.

[0061] Heating component 33: usually includes two sets of upper and lower heating tubes or infrared heating elements, which are used to bake food; at the same time, it may also be equipped with an independent steam generator, which heats water through electric heating elements to generate steam to achieve the steaming function.

[0062] Insulation assembly 34: This assembly consists of insulation foam and insulation panels. These wrap around the exterior of the cavity and the interior areas that don't come into direct contact with the food, minimizing heat loss and maintaining a constant temperature within the cavity. The insulation foam provides excellent heat insulation and sound absorption, while the insulation panels are more durable and sturdy. Together, they ensure efficient and energy-efficient operation.

[0063] Furthermore, in this embodiment, the thermal insulation assembly 34 and the cavity assembly 31 employ a contoured design. Specifically, the shape of the thermal insulation assembly 34 matches the outer wall of the cavity assembly 31. This conformity maximizes the contact area between the thermal insulation assembly 34 and the cavity assembly 31, resulting in a tighter fit between the thermal insulation assembly 34 and the cavity assembly 31, reducing gaps for heat transfer and thereby improving the thermal insulation effect. This design effectively reduces heat transfer from the cavity assembly 31 to the thermal insulation assembly 34, thereby reducing heat loss and improving overall thermal efficiency.

[0064] The integrated steam oven not only realizes diversified cooking methods through the coordinated work of various components, but also achieves high efficiency, energy saving, safety and comfortable use requirements while ensuring cooking results.

[0065] The left and right sides of the inner chamber 312 and the side panels 112 of the range hood body 1 form side flues 41 on either side of the cooking device. The wide side flues 41 on both sides lower the temperature rise of the cover assembly 11 of the integrated range hood, improving installation performance in wall cabinets.

[0066] In a preferred embodiment, the widths of the two side flues 41 are the same.

[0067] In another preferred embodiment, the back of the range hood body 1 is tightly attached to and fixedly connected to the back of the integrated steam oven body, leaving no gap between the two, preventing oil smoke from passing through, and they can even share a back panel.

[0068] This design brings the following significant benefits:

[0069] Enhanced exhaust effect: The side flue 41 design can maximize the use of space and increase the exhaust channel area. No matter which stove eye is used for cooking, the oil smoke generated during the cooking process can be quickly and smoothly inhaled and discharged, effectively avoiding the accumulation of oil smoke inside the equipment, keeping the kitchen air fresh, and improving the quality of the cooking environment.

[0070] Improve energy efficiency: Due to the scientific and reasonable layout of the flue 4, the path for the oil smoke to rise and be discharged is increased, and the time for the oil smoke to circulate inside the cavity is reduced. Therefore, the oil smoke can be discharged more quickly, thereby improving the energy utilization efficiency of the equipment and reducing energy consumption.

[0071] Reduce the size of the equipment: The flue 4 is formed by the cavity inner tank 312 and the side panel 112 of the range hood body 1. This integrated design simplifies the overall structure. Compared with the traditional independent exhaust duct, it can reduce the space occupied by the equipment without sacrificing the exhaust effect, which is beneficial to the overall layout and space optimization of the kitchen.

[0072] Easy to clean and maintain: The side flue 41 is relatively centralized in design, without complicated corners and hard-to-reach areas, making cleaning more convenient and helping to extend the service life of the equipment. It also meets the needs of modern families for easy cleaning and maintenance of kitchen equipment.

[0073] Reduce noise impact: Reasonable flue 4 design can also achieve a certain sound insulation effect. By controlling the flow path and speed of oil smoke, it reduces the noise caused by airflow impact, making the cooking process quieter and more comfortable.

[0074] In a preferred embodiment, at least two smoke inlets 14 are provided on the bottom plate 111 of the range hood body 1. At least one smoke inlet 14 is provided below each side smoke duct 41.

[0075] The range hood's smoke outlet 14, also known as the air intake or inlet, is the key component of the entire range hood system closest to the cooking source. Its structural design directly affects the efficiency and effectiveness of fume absorption. The following is a detailed structure and features of the smoke outlet 14:

[0076] Structural Form: The opening of the smoke outlet 14 is typically a long strip or ring of a certain width, sometimes even with an inclined or corrugated structure, to increase the contact area and guide the flow of oil smoke. The surrounding area of ​​the smoke outlet 14 is often made of smooth, easy-to-clean materials such as stainless steel or glass to prevent oil stains from adhering.

[0077] Oil guide trough and oil screen design: The interior or front of the smoke outlet 14 is typically equipped with an oil guide trough and oil screen. Made of a fine metal mesh or special material, the oil screen performs a preliminary separation of oil smoke entering the range hood, intercepting large grease particles that drip back into the cooking area while allowing smaller smoke particles to pass through the oil screen and enter the suction system. The oil guide trough, located below the oil screen, collects and concentrates grease for easy cleaning.

[0078] Attraction-Guided Design: The shape and positioning of the smoke vent 14 create a negative pressure zone, leveraging the powerful suction force of the fan to quickly and effectively draw cooking fumes into the range hood. Some advanced models also feature a curved or angled smoke trap. This structure effectively traps fumes above the cookware, minimizing their spread and improving their extraction efficiency.

[0079] Adjustable design: The smoke outlet 14 of some new models of range hoods has a retractable or adjustable function, which can flexibly adjust the position and size of the smoke outlet 14 according to the size of the cooking utensils and the user's habits to adapt to different cooking scenes and further improve the smoking efficiency.

[0080] Safety and hygiene considerations: Fire-retardant materials are often used around the smoke outlet 14 to ensure safety during cooking. At the same time, to avoid accidental contact with hands during cooking, the edges of the smoke outlet 14 may be rounded to reduce the risk of burns.

[0081] The design of the above-mentioned smoking port 14 and side flue 41 has the following beneficial effects:

[0082] All-round three-dimensional smoke capture: The design of multiple smoke outlets 14 can fully capture the oil smoke generated during the cooking process from different angles and heights. No matter which direction the oil smoke rises from in the steam oven cavity, it can be quickly and effectively extracted, greatly improving the oil smoke extraction rate and keeping the kitchen environment clean.

[0083] Enhanced smoke removal effect: Multiple smoke inlet points at the bottom and sides create a stronger negative pressure zone for oil smoke in the cavity, preventing the oil smoke from stagnating and allowing it to be sucked away in a short time, thereby achieving better smoke removal effect, protecting indoor air quality, and reducing the potential harm of oil smoke to human health.

[0084] Adapt to various cooking modes: In view of the different amounts of oil smoke and oil smoke rising paths generated by different cooking modes of the steam oven, such as grilling and steaming, the multi-smoke outlet 14 design can respond flexibly to ensure that both a large amount of oil evaporation and a small amount of water vapor can be discharged in time.

[0085] Improve equipment efficiency: By dispersing the oil smoke inlet, the wind pressure in various parts can be balanced to a certain extent, avoiding excessive load on a single smoke outlet 14, improving equipment operation stability and extending equipment service life.

[0086] Easy to clean and maintain: The 14-port design with multiple smoke extraction ports can disperse the accumulation of oil smoke, reduce the cleaning pressure of a single part, and facilitate daily maintenance and cleaning.

[0087] The integrated range hood of the present invention has external dimensions of 800-900mm in width, 300-400mm in depth, and 900-1300mm in height, which are universal installation dimensions of range hoods. In order to improve space utilization, the width is preferably 895mm, the depth is 380mm, and the height is 1000mm.

[0088] The inner chamber 312 is a cooking area with a volume of 30 to 70 liters. This invention breaks with existing definitions of oven volume by defining the oven cavity depth based on the depth of current household wall cabinets. This solution proposes two criteria: one is that the depth of the integrated range hood matches the depth of the wall cabinet, enabling flush installation; the other is that the cavity depth matches the depth of the wall cabinet, ensuring that the oven is flush with the wall cabinet when the door is opened. The preferred cavity volume is 50 liters, and the cavity depth is 350 mm, which is flush with the wall cabinet. The preferred width is 535 mm.
