Abstract
Description
Technical Field
[0001] This utility model relates to the field of range hood technology, and more specifically to a range hood with annular air intake. Background Technology
[0002] Currently, the only known smoke extraction path for range hoods is through the central air inlet mesh to the impeller in the volute, which then ejects the smoke into the exhaust pipe, achieving the desired smoke extraction effect. The structural components along this path include the inlet grease filter, the fan assembly, and the exhaust vent. Most household range hoods currently use large-area air intakes, meaning a large air inlet is located on the front of the hood, equipped with an inlet grease filter. While large inlets allow for a wide air intake range, insufficient power in the fan assembly affects smoke extraction efficiency. Existing technology typically uses the inlet grease filter to condense grease from the fumes, resulting in weak grease filtration. Some grease adheres to the fan assembly, severely impacting the impeller's efficiency, increasing its load, and consequently increasing the load on the motor, ultimately affecting smoke extraction performance. Utility Model Content
[0003] In view of this, the present invention provides a range hood with annular air intake.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a range hood with annular air intake, comprising: a smoke collection hood and a wind power component disposed on the smoke collection hood, the smoke collection hood being provided with an air inlet, an oil screen being provided at the air inlet, and further comprising: a cloud plate;
[0005] The cloud plate is located outside the smoke hood and directly opposite the air inlet. The cloud plate and the smoke hood are connected by a connecting component. An air inlet gap is formed between the cloud plate and the surface of the smoke hood where the air inlet is provided.
[0006] In a preferred embodiment of this utility model, the projection of the cloud plate on the smoke collection hood covers the air inlet.
[0007] As a preferred embodiment of this utility model, the cloud plate is inclined downward from the front to the rear.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0029] For range hoods with a circular air intake, please refer to [link / reference]. Figure 1-6 As shown, it includes: a smoke collection hood 100 and a wind power component disposed on the smoke collection hood 100. The smoke collection hood 100 is provided with an air inlet 101, and an oil mesh 110 is provided at the air inlet 101. Here, the specific structure of the wind power component is not described in detail. The wind power component adopts existing technology and draws in oil fumes from the air inlet 101 during operation.
[0030] The range hood with annular air intake in this technology also includes: cloud plate 120.
[0031] The cloud plate 120 is located outside the smoke hood 100 and directly opposite the air inlet 101. The cloud plate 120 and the smoke hood 100 are connected by a connecting component 140. An air inlet gap 102 is formed between the cloud plate 120 and the surface of the smoke hood 100 where the air inlet 101 is provided.
[0032] like Figure 1 As shown, assume the back of the range hood ( Figure 1 The range hood (on the left) is installed on the kitchen wall, and the area below it corresponds to the stove. After installing the cloud plate 120, the distance between the cloud plate 120 and the stove is less than the distance between the air inlet 101 and the stove. This means that the smoke collection height is lowered, and the oil fumes enter the air inlet 101 through the air inlet gap 102, effectively capturing and dispersing oil fumes and condensing oil fumes, slowing down the oil fumes to prevent diffusion, concentrating the airflow, strengthening the suction, and improving the smoke extraction effect.
[0033] like Figure 1 As shown, the lower surface of the cloud plate 120 can be a smooth surface. The oil fumes rise and hit the lower surface of the cloud plate 120 and move along the lower surface of the cloud plate 120. The oil fumes move to all sides and are sucked into the air inlet gap 102, and finally enter the air inlet 101.
[0034] When the fumes impact the lower surface of the cloud plate 120, the grease adheres to the surface of the cloud plate 120 and is collected. When the fumes enter the air inlet 101 through the air inlet gap 102, they pass through the oil mesh 110 for a second grease collection, effectively improving the fumes separation effect.
[0035] Furthermore, the projection of the cloud plate 120 onto the smoke hood 100 covers the air inlet 101.
[0036] Specifically, continue as Figure 1 As shown, assuming the direction of illumination is from bottom to top, the projection of the cloud plate 120 covers the air inlet 101.
[0037] Furthermore, the area of the cloud plate 120 can be larger than the area of the air inlet 101, thereby increasing the smoke collection area.
[0038] like Figure 3 As shown, the air inlet 101 is rectangular in shape, and the oil mesh 110 is rectangular and installed on the air inlet 101. The oil mesh 110 is provided with multiple elongated oil mesh holes, which are arranged in a distributed manner. Correspondingly, the cloud plate 120 is rectangular.
[0039] There are gaps between the four sides of the cloud plate 120 and the smoke hood 100, so an annular air intake gap 102 is formed between the cloud plate 120 and the surface of the smoke hood 100 where the air inlet 101 is provided, which can allow air to enter from 360°.
[0040] In one embodiment, the cloud plate 120 is inclined downwards from the front to the rear, and so on. Figure 1 As shown, Figure 1 The left side of the orientation corresponds to the rear side of the cloud board 120, and the right side corresponds to the front side of the cloud board 120.
[0041] Furthermore, continue as Figure 1 As shown, the cloud plate 120 forms an angle α with the horizontal plane, where 0° < α < 90°. Preferably, the angle α between the cloud plate 120 and the horizontal plane can be selected as 10°, 15°, 20°, 25°, 30°, or 35°.
[0042] In one implementation, such as Figure 2 As shown, the smoke hood 100 is equipped with an oil collection cup 130, which is located below the rear side of the cloud plate 120. The oil collection cup 130 is mainly used to collect the grease flowing down from the cloud plate 120 and the oil net 110.
[0043] Optionally, the oil collection cup 130 is set to be slightly longer than the cloud plate 120, which can effectively collect the grease dripping from the cloud plate 120.
[0044] The cloud plate 120 is tilted downwards from the front to the rear, which also makes it easier for the grease on the cloud plate 120 to drip into the oil collection cup 130.
[0045] In one embodiment, the cloud plate 120 can be fixedly installed with the smoke hood 100 or it can be lifted and lowered. In the fixed installation method, the position of the cloud plate 120 remains unchanged, the size of the air inlet gap 102 remains unchanged, and the structure is simple.
[0046] The lifting installation allows the cloud plate 120 to be lowered when the range hood is in use and raised when the range hood is not in use to block the air inlet 101, thus providing protection such as dust prevention and preventing cockroaches from crawling into the smoke collection hood 100 from the air inlet 101.
[0047] In this embodiment, the cloud plate 120 and the smoke hood 100 are fixedly installed.
[0048] Specifically, such as Figure 3 As shown, the connection component 140 includes: two female connectors 142 disposed on the cloud plate 120 and a male connector 141 disposed on the smoke hood 100 corresponding to the female connectors 142. Between the male connector 141 and the female connector 142, one of them is provided with a socket and the other is provided with a pin.
[0049] like Figure 3 and Figure 4 As shown, the female connector 142 is provided with a pin 1421 and the male connector 141 is provided with a socket 1411; the cloud plate 120 is inserted into the bottom of the smoke hood 100 through the cooperation of the female connector 142 and the male connector 141.
[0050] Continue as Figure 3 and Figure 4As shown, there are two female connectors 142 and two male connectors 141. The female connectors 142 are located on the left and right sides of the cloud plate 120 near the front, and the position of the male connectors 141 on the smoke hood 100 corresponds to that of the female connectors 142.
[0051] Optionally, the female connector 142 and the male connector 141 are plugged in and then tightened with screws to enhance the stability of the cloud plate 120 assembled on the smoke hood 100.
[0052] Optionally, the male connector 141 can be a push-button connector, which may be equipped with a trigger button assembly, including a locking tongue, a button, and a spring. The female connector 142 has a locking groove on its pin 1421. When the pin 1421 is inserted into the socket 1411, the male connector 141 and the female connector 142 are locked by the cooperation of the locking tongue and the locking groove. When the cloud plate 120 needs to be removed for cleaning, pressing the button will unlock the male connector 141 and the female connector 142, making it easy to disassemble the cloud plate 120.
[0053] Furthermore, the connecting assembly 140 includes: a connector 150 disposed on the smoke hood 100, the connector 150 being located on the rear side of the smoke hood 100, and the connector 150 being provided with a first slot 151 and a second slot 152;
[0054] The opening of the first slot 151 faces the rear side of the cloud plate 120, and the rear side of the cloud plate 120 is provided with a insert 121, the insert 121 of the cloud plate 120 as follows: Figure 3 Insert the plate into the first slot 151 in the direction indicated by the arrow; by cooperating with the male connector 141 and female connector 142, and by inserting the insert 121 into the first slot 151, the cloud plate 120 is stably installed on the smoke hood 100.
[0055] There are two second slots 152. One second slot 152 opens towards the left side of the smoke hood 100, and the other second slot 152 opens towards the right side of the smoke hood 100. The openings of both second slots 152 are L-shaped.
[0056] like Figure 5 As shown, the smoke hood 100 is equipped with an oil collection cup 130, and the oil collection cup 130 is equipped with a support plate 131, the support plate 131 as follows: Figure 3 Insert the oil collection cup 130 into the second slot 152 in the direction indicated by the arrow to complete the installation. When the oil collection cup 130 needs to be removed for cleaning, move the oil collection cup 130 along... Figure 3 Simply pull it out in the opposite direction indicated by the arrow; assembly is simple and quick.
