Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and particularly relates to an integrated range hood. Background Art

[0002] With the rapid development of technology, modern families have increasingly higher requirements for kitchen appliances, especially for the performance and quality of range hoods. As an important device in the kitchen, the range hood not only undertakes the responsibility of sucking out the cooking fumes, but also gradually incorporates the design concepts of intelligence, health and environmental protection to improve the user experience and the quality of the kitchen environment.

[0003] Most of the range hoods on the current market have the basic function of sucking and exhausting cooking fumes. Through mechanical structures and air suction principles, the cooking fumes are sucked in and discharged outdoors. With the progress of technology, many products also incorporate intelligent control technologies, such as touch screens, intelligent sensors, etc., enabling users to operate and control the range hood more conveniently.

[0004] As an essential electrical appliance in the kitchen, the main function of the range hood is to quickly discharge the cooking fumes and odors generated during cooking outdoors through strong suction to keep the kitchen air fresh. However, while traditional range hoods efficiently exhaust air, they are often accompanied by relatively loud noises, which to a certain extent affect the user experience and the quality of life. Content of the Utility Model

[0005] The utility model aims at the technical problems existing in the prior art, and provides an integrated range hood to solve the problem of large noise during the operation of the range hood.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: an integrated range hood, including an air box and an oil fume collection hood arranged below the air box; a partition is horizontally arranged in the inner cavity of the air box, and the partition divides the inner cavity of the air box into an upper chamber and a lower chamber;

[0007] A number of diversion blowers for sucking the oil fumes in the oil fume collection hood into the lower chamber are installed in the lower chamber of the air box; one end of the partition is provided with a communication port for communicating the upper chamber and the lower chamber;

[0008] A high-pressure blower is further provided at one end of the upper chamber of the air box far away from the communication port; an exhaust hood communicated with the air outlet of the high-pressure blower is also installed on the air box

[0009] On the basis of the above technical solution, the utility model can be further improved as follows.

[0010] Further, a diversion plate for fixing the diversion blower and arranged obliquely from outside to inside is also provided in the air box.

[0011] Further, an oil leakage port is provided at the bottommost side of the flow guide plate, and a detachable oil collecting hood is arranged directly below the oil leakage port along the oil fume collecting hood.

[0012] Further, a flow guide protrusion is also arranged on the flow guide plate between adjacent flow guide fans.

[0013] Further, a silencing net plate, a transverse flow dividing grille, and a vertical flow dividing column group are sequentially arranged in the upper chamber of the air box along the communication port towards the high-pressure fan.

[0014] Further, two groups of the transverse flow dividing grilles are continuously arranged, and multiple groups of vertically and horizontally spaced horizontal flow dividing air channels are formed in each group of the transverse flow dividing grilles.

[0015] Further, multiple groups of horizontally arranged and vertically spaced vertical flow dividing air channels are formed in the vertical flow dividing column group.

[0016] Further, uniformly distributed sound absorption holes are provided on the silencing net plate.

[0017] The effective effects of the present utility model are as follows:

[0018] 1. Through the synergistic effect of the oil fume collecting hood and multiple flow guide fans, the oil fume generated during cooking can be quickly and effectively sucked into the air box, ensuring that the oil fume is processed in a timely manner, avoiding the diffusion of oil fume in the kitchen, and keeping the kitchen air fresh.

[0019] 2. The interior of the air box is divided into an upper chamber and a lower chamber by a partition plate.

[0025] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0026] It should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" in the terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0027] As Figure 1 and Figure 2 shown, the integrated range hood designed by the present utility model includes a bellows 1 and an oil fume collection hood 2 provided below the bellows 1; a partition board 1.1 is horizontally arranged in the inner cavity of the bellows 1, and the partition board 1.1 divides the inner cavity of the bellows 1 into an upper cavity and a lower cavity;

[0028] A number of diversion fans 3 for sucking the oil fume in the oil fume collection hood 2 into the lower cavity are installed in the lower cavity of the bellows 1; one end of the partition board 1.1 is provided with a communication port 1.2 for communicating the upper cavity and the lower cavity;

[0029] A high-pressure fan 4 is further provided at one end of the upper cavity of the bellows 1 away from the communication port 1.2; an exhaust hood 5 communicated with the air outlet of the high-pressure fan 4 is also installed on the bellows 1

[0030] This range hood is mainly composed of a bellows 1 and an oil fume collection hood 2 provided below it. The inside of the bellows 1 is divided into two independent spaces, an upper cavity and a lower cavity, by a horizontally arranged partition board 1.1. This design helps to optimize the air flow path and improve the efficiency of oil fume treatment.

[0031] During operation, the oil fume is first captured and gathered by the oil fume collection hood 2. Subsequently, a plurality of diversion fans 3 in the lower cavity of the bellows 1 are started, and they generate a strong suction force to suck the oil fume in the oil fume collection hood 2 into the lower cavity. This step ensures that the oil fume can be quickly and effectively drawn into the bellows for subsequent purification treatment.

[0032] After the preliminary collection in the lower chamber, the fume enters the upper chamber through the communication opening 1.2 formed on the partition plate 1.1. Inside the upper chamber, a high-pressure blower 4 is provided at one end far from the communication opening 1.2. The function of the high-pressure blower 4 is to further accelerate and compress the air flow to ensure that the fume can be discharged outdoors smoothly and efficiently through the exhaust system.

[0033] Finally, the air flow accelerated by the high-pressure blower 4 is discharged through the exhaust hood 5. The exhaust hood 5 is connected to the air outlet of the high-pressure blower 4. It plays a role in guiding and protecting the air flow, ensuring that the fume can be discharged smoothly along the predetermined path, and preventing foreign impurities from entering the inside of the air box.

[0034] As an implementation manner, a guide plate 6 for fixing the diversion blower 3 and arranged obliquely from outside to inside is further provided in the air box 1.

[0035] The guide plate 6 is designed to be arranged obliquely from the outside to the inside of the air box 1, mainly for fixing and supporting the diversion blower 3. This inclined arrangement not only helps to stabilize the diversion blower 3, but also guides the flow direction of the fume in the air box, improving the collection efficiency of the fume. Through the carefully designed inclination angle, the guide plate 6 can ensure that a smoother air flow path is formed when the fume flows through, reducing the generation of eddies and turbulence, thereby reducing noise and improving the purification effect of the fume.

[0036] Specifically, an oil leakage port is formed at the bottommost side of the guide plate 6, and a detachable oil collecting hood 7 is arranged directly below the oil leakage port along the fume collecting hood 2.

[0037] The fume collecting hood 2 is provided with a detachable oil collecting hood 7 directly below the oil leakage port. The oil collecting hood 7 can conveniently collect the grease flowing out of the oil leakage port, avoiding the accumulation and dripping of grease inside the air box, thereby keeping the air box clean and hygienic.

[0038] Specifically, a guide protrusion 6.1 mounted on the guide plate 6 is further provided between adjacent diversion blowers 3 to guide the grease to gather at the oil collecting hood 7.

[0039] As an implementation manner, a sound-absorbing net plate 8, a transverse diversion grille 9 and a vertical diversion column group 10 are sequentially arranged in the upper chamber of the air box 1 along the communication opening 1.2 towards the high-pressure blower 4.

[0040] Specifically, two groups of the transverse diversion grilles 9 are continuously arranged, and multiple groups of vertical and horizontally spaced horizontal diversion air channels are formed in each group of the transverse diversion grilles 9.

[0041] Specifically, multiple groups of horizontally arranged and vertically spaced vertical diversion air channels are formed in the vertical diversion column group 10.

[0042] Specifically, sound-absorbing holes are uniformly distributed on the sound-absorbing net plate 8.

[0043] The sound-absorbing net plate 8 is placed after the communication port 1.2 and serves as the first processing device before the oil fume airflow enters the high-pressure fan 4. The sound-absorbing holes evenly distributed on it can effectively slow down the flow velocity of the airflow, causing the airflow to diffuse and collide when passing through, thereby consuming part of the energy and achieving the purpose of reducing noise. This design helps to reduce the eddy current and turbulence generated at the inlet of the high-pressure fan 4 and lower the noise generated due to airflow disorder.

[0044] There are two sets of continuously arranged horizontal diversion grilles 9, and multiple sets of vertical and horizontally spaced horizontal diversion air channels are formed inside each set. These horizontal diversion air channels can further disperse and homogenize the airflow passing through the sound-absorbing net plate 8. When the airflow passes through the horizontal diversion grille 9, it will be guided into different horizontal diversion air channels, thereby realizing the horizontal diversion and speed adjustment of the airflow. This design helps to reduce the flow velocity gradient of the airflow at the inlet of the high-pressure fan 4 and reduce the noise and vibration generated due to uneven flow velocity.

[0045] The vertical diversion column group 10 is located after the horizontal diversion grille 9, and multiple sets of horizontally arranged and vertically spaced vertical diversion air channels are formed inside it. These vertical diversion air channels can further disperse and homogenize the airflow processed by the horizontal diversion grille 9 in the vertical direction. When the airflow enters the vertical diversion column group 10, it will be guided into different vertical diversion air channels to achieve the vertical diversion and speed adjustment of the airflow. This design helps to further improve the uniformity and stability of the airflow, provide a more stable airflow input for the high-pressure fan 4, and thus reduce noise and vibration.
