Description

Technical Field

[0001] This utility model relates to the field of integrated stove accessories, and in particular to an integrated stove volute filter. Background Technology

[0002] The existing filter structure in integrated stoves is generally installed inside the flue, such as 201921447484 .9. However, this filter can only block impurities from entering the flue and cannot guide the oil fumes entering the integrated stove fan. When the integrated stove fan volute takes in air, the airflow direction is turbulent, impacting the flue and volute, resulting in loud noise and weakened airflow, which is not conducive to the settling of oil stains in the oil fumes. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated stove volute filter screen that reduces noise, increases airflow, and facilitates the settling of oil stains in cooking fumes.

[0004] To achieve this objective, the present invention adopts the following technical solution: an integrated stove volute filter screen, fixed at the air inlet of the integrated stove fan volute, including an oil guide cover protruding from the periphery to the center, the oil guide cover protruding outward from the integrated stove fan volute, the oil guide cover having a plurality of elongated air guide holes distributed circumferentially, all the air guide holes being uniformly curved into an arc shape along the rotation direction of the integrated stove fan; the air inlet side of the air guide cover is located at one edge of the air guide hole and has a guide edge inclined in the air inlet direction. When the integrated stove fan rotates, the designed air guide holes and guide edges can adapt to the spiral air intake of the integrated stove fan volute. The guide edges and air guide holes can guide the oil fumes into the air guide holes along the rotation direction of the integrated stove fan, thereby avoiding the problem of turbulent airflow when oil fumes enter the integrated stove fan volute, impacting the flue and volute, reducing noise, and enhancing airflow. The oil guide cover protrudes from the outside to the middle, which can further increase the contact area between oil fumes and guide edges and oil guide covers, improving the adsorption effect of oil stains in oil fumes. Moreover, the guide edges and air guide holes guide oil fumes into a spiral shape, improving the fusion and collision effect of oil stain particles, which is more conducive to oil stains settling and purification.

[0005] Furthermore, an oil-collecting vent is formed in the middle of the oil guide cover. The spiral-shaped oil fumes are drawn in through the oil-collecting vent, which facilitates the collision and fusion of oil particles in the fumes, and further promotes oil settling and purification.

[0006] Furthermore, the width of the air guide hole gradually narrows from the outer periphery of the oil guide cover towards the center. The larger outer periphery provides a larger suction area, while the narrower center results in stronger suction, further facilitating the drawing of oil fumes into a spiral shape, which promotes the collision, binding, and settling of oil stains within the fumes.

[0007] Furthermore, the oil guide cover is circular, and an annular mounting edge is formed around its periphery, with mounting holes provided on the mounting edge. This facilitates assembly and disassembly.

[0008] The beneficial effects of this utility model are: This product can guide oil fumes into the integrated stove fan volute in a spiral shape, reducing noise and increasing airflow, while also facilitating the collision, fusion, and settling of oil particles. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the invention and not all structures. In the description of the present invention, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0021] like Figure 1-8 As shown, an integrated stove volute filter screen is fixed at the air inlet of the integrated stove fan volute 100. The integrated stove fan has an integrated stove fan volute 100 and a fan wheel. The fan wheel is located inside the integrated stove fan volute 100. Moreover, the integrated stove fan is installed in the existing integrated stove flue. The integrated stove fan outlet is connected to the exhaust flue. This part of the structure is an existing product and is not within the scope of protection of this patent. It is a conventional component in this field. This product protects an integrated stove volute filter screen, including an oil guide cover 1. The oil guide cover 1 is installed at the right side inlet of the integrated stove fan, with the bottom of the integrated stove fan serving as the outlet. The oil guide cover 1 protrudes from the outer periphery towards the center, and the oil guide cover 1 protrudes outward from the integrated stove fan volute 100, that is, the center of the oil guide cover 1 protrudes to the right. The oil guide cover 1 has 30 elongated air guide holes 2 evenly distributed circumferentially. Of course, the number of air guide holes 2 can be designed as needed. All air guide holes 2 are uniformly curved in an arc shape along the rotation direction of the integrated stove fan. That is, when the integrated stove fan rotates counterclockwise, all air guide holes 2 are uniformly concave in an arc shape in the counterclockwise direction, forming a spiral shape similar to a fan. One outer edge of the air guide hole 2 is connected to a guide edge 21 that is inclined towards the air intake direction. That is, the air intake side of the air guide cover has a guide edge 21 on one side edge of the air guide hole. The guide edge 21 is inclined towards the air intake direction, which can obliquely introduce the air into the integrated stove fan and avoid conflict with the opposite airflow direction. Figure 1 , Figure 6 , Figure 7 As shown.

[0022] The oil guide cover 1 has an oil-gathering air hole 3 in the middle, and the oil-gathering air hole 3 is circular.

[0023] Furthermore, in order to further improve the performance, the width of the air guide hole 2 gradually narrows from the outer periphery of the oil guide cover 1 towards the center.

[0024] For ease of installation, the oil guide cover 1 is circular, and an installation edge 4 is formed around the outer perimeter of the oil guide cover 1. The installation edge 4 is also annular, and six installation holes 41 are evenly distributed on the installation edge 4. The installation holes 41 can be fixed to the air inlet of the integrated stove fan by screws.

[0025] The integrated stove fan rotates counterclockwise, causing the oil fumes to spiral counterclockwise into the air inlet of the integrated stove fan casing. The air guide hole 2 and the guide edge 21 further guide the oil fumes into a counterclockwise spiral shape into the air inlet of the integrated stove fan casing, avoiding turbulent airflow, reducing noise, and enhancing airflow.

[0026] Meanwhile, the width of the air guide hole 2 gradually narrows from the outer periphery of the oil guide cover 1 towards the center, resulting in a large air volume but low wind force at the outer periphery and a small air volume but high wind force in the center. While gathering oil fumes, it further guides the oil fumes into a spiral shape, and then enters the air inlet of the integrated stove fan volute from the center of the oil guide cover. It also increases the contact area between the oil fumes and the oil guide cover 1, which on the one hand facilitates the oil fumes to be adsorbed in the center of the oil guide cover 1, and on the other hand, guides the oil fumes into a spiral shape, which is conducive to the spiral aggregation of oil particles in the oil fumes, increases the probability of collision and fusion of oil particles, and then settles and adsorbs them in the exhaust duct, thereby improving the removal effect of oil stains in the oil fumes.

[0027] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
