Description

Technical Field

[0001] The utility model relates to the field of kitchen and bathroom, in particular to a front oil-blocking plate of an oil fume machine and an oil fume machine. Background Art

[0002] An oil fume machine is a kitchen utensil that separates oil and fume to achieve the effects of oil absorption and fume collection. It usually includes an oil-blocking plate and an air inlet device. Among them, there are three existing forms of the oil-blocking plate: a single-layer filter plate structure, a single-layer filter screen structure, and a combined structure of a filter plate and a filter screen. Due to the direct connection of the ventilation holes in these three structures to the air inlet device, the noise of the air inlet device is directly transmitted, resulting in excessive noise and affecting the use experience. In addition, since the ventilation holes are single-layer or the double-layer ventilation holes are opposite, the path for the fume to enter the interior of the oil fume machine is short, so the fume separation process is also short, and the fume separation is not sufficient. The structure setting of the oil-blocking plate of the oil fume machine urgently needs to be improved. Content of the Utility Model

[0003] The first object of the present invention is to overcome the deficiencies of the unreasonable structure setting of the existing oil-blocking plate, such as large noise and insufficient fume separation. By setting a double-layer filter plate structure with the double-layer ventilation holes arranged in a staggered manner, the transmission and entry paths of noise and fume are increased, so that the noise is smaller and the fume separation is more sufficient during use.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A front oil-blocking plate of an oil fume machine includes a first filtering structure and a second filtering structure. The second filtering structure and the first filtering structure enclose to form an installation cavity, and a filter cotton is arranged in the installation cavity. The first filtering structure includes a first filter plate, the second filtering structure includes a second filter plate, a first ventilation hole is arranged on the first filter plate, a second ventilation hole is arranged on the second filter plate, and the first ventilation hole and the second ventilation hole are arranged in a staggered manner.

[0006] The present invention adopts a double filtering structure to double-block the transmission of noise in the air inlet device, so that the noise cannot be directly transmitted from the ventilation holes, thereby minimizing the use noise as much as possible. At the same time, the first ventilation hole and the second ventilation hole are arranged in a staggered manner. When sucking in air, the fume needs to experience a certain turning path to reach the interior of the oil fume machine, increasing the path of the fume and making the oil collection more sufficient. Compared with the prior art, the ventilation hole setting of the front oil-blocking plate of the oil fume machine of the present invention is more reasonable. When applied to an oil fume machine, it can better improve the noise reduction and oil filtering effects of the oil fume machine and improve the user experience.

[0007] Preferably, the area of the first ventilation hole accounts for 20% of the area of the first filter plate, and the area of the second ventilation hole is 50% - 110% of the area of the second ventilation hole.

[0008] The first ventilation hole area of 15% - 35% can, on the basis of reducing noise, provide sufficient ventilation hole area to absorb smoke, while the remaining 65% - 85% of the first filter plate area is used for condensing grease. Since a part of the oil fume has been separated on the first filter plate, when the oil fume reaches the second filter plate, the second ventilation holes can separate the grease and smoke more meticulously, enabling purer smoke to pass through the second ventilation holes, thereby ensuring sufficient oil fume filtration.

[0009] Preferably, the first ventilation holes are arranged along both sides and the upper side of the first filter plate, presenting an overall U-shaped structure, and the second ventilation holes are arranged in the middle of the second filter plate and correspond to the middle of the first filter plate.

[0010] The first ventilation holes and the second ventilation holes are arranged in a staggered manner. On the one hand, it can prevent the noise of the air inlet device from directly transmitting due to the same-position arrangement of the ventilation holes, resulting in excessive use noise and affecting the user experience. On the other hand, it makes the ventilation holes on the two filter plates not form a direct path, increasing the path of the oil fume, making the oil fume separation process longer, so that the oil fume filtration is more sufficient. At the same time, it can also prevent part of the oil fume from directly entering the interior of the range hood through the two layers of ventilation holes, resulting in a large amount of oil accumulation inside the range hood, thereby increasing the power consumption of the range hood. In addition, the U-shaped distribution of the first ventilation holes can expand the oil fume inhalation range, enabling the oil fume at the edge of the range hood to be inhaled as well, so that the oil fume absorption is more complete.

[0011] Preferably, it further includes an installation structure, which is arranged on the first filtering structure or the second filtering structure. The installation structure includes a plug protrusion and a hook connecting piece. Protrusions are provided on both the upper and lower sides of the plug protrusion, and the hook connecting piece extends downward and is hooked and folded. The installation structure is used to connect with the range hood.

[0012] Preferably, the first filtering structure further includes a panel and a flanging arranged along the edge of the panel. The panel and the flanging jointly enclose a cavity with an open upper end, and the second filtering structure closes the cavity to form the installation cavity. The first ventilation holes are arranged on the panel.

[0013] The staggered arrangement of the first ventilation holes and the second ventilation holes and the installation cavity can make the wind pressures passing through the two filter plates different, thereby forming a vortex in the installation cavity, increasing the entrainment of the incoming air on the smoke, having a better smoke-gathering effect, thus enhancing the oil fume separation effect, and making the oil fume absorption more sufficient.

[0014] Preferably, the panel includes the first filter plate, and the area of the second filter plate accounts for 90% - 95% of the area of the first filter plate, or the area of the first filter plate is 90% - 95% of the area of the second filter plate.

[0015] Preferably, the first ventilation holes are set in a strip shape.

[0016] Preferably, the second ventilation holes are circular.

[0017] Another object of the present invention is to provide a range hood, comprising a range hood body, an inclined oil collecting plate is provided on the range hood body, an inwardly concave air inlet part is provided on the oil collecting plate, an air inlet and an oil collecting structure are provided on the air inlet part, the air inlet is located in the middle of the air inlet part, the oil collecting structure is arranged on both sides of the air inlet, and the front oil blocking plate is adaptively arranged in front of the air inlet part and is balanced with the oil collecting plate. Compared with the prior art, due to the application of the above scheme, the present invention has better noise reduction effect and more sufficient oil fume filtration.

[0018] Preferably, insertion parts and hook connection components are symmetrically arranged on one side of the air inlet part facing the front oil blocking plate, the insertion protrusion is inserted on the insertion parts, and the hook connection part is hooked with the hook connection components.

[0019] Preferably, an extension part is provided on the flanging, and a plurality of clamping interfaces are provided at the lower part of the front side of the second filter plate. The plurality of clamping interfaces are evenly distributed along the length direction of the second filter plate, and the clamping interfaces are used for being clamped on the extension part.

[0020] During use, oil fume is sucked into the range hood from the outside through the suction of the air inlet device. When passing through the front oil blocking plate, oil droplets with greater weight and volume are blocked by the double-layer structure of the front oil blocking plate, condense and slide off on the first filter plate and the second filter plate for collection, while the lighter smoke passes through the ventilation holes arranged in a staggered manner into the interior of the range hood in sequence. During this process, the oil fume continues to be separated and is fully disturbed in the installation cavity of the front oil blocking plate, and finally is sucked by the air inlet device, so as to achieve the effect of oil fume separation treatment. At the same time, the noise generated when the air inlet device works needs to pass through the second ventilation holes and the first ventilation holes arranged at different positions in sequence to diffuse out of the range hood. The diffusion path is relatively long, and the noise is gradually weakened during the diffusion process, so that the noise transmitted out of the range hood can be greatly reduced.
