Description

Technical Field

[0001] This application relates to the field of kitchenware, and in particular to a three-fold separator and a range hood. Background Technology

[0002] Range hoods are primarily used to absorb and remove cooking fumes. The separator installed on the range hood is used to separate the oil from the fumes. Currently, common range hood fume separation devices use single-layer or multi-layer filters, or simple single-layer or multi-layer perforated plates. The existing CN210356555U discloses an S-shaped vortex condensing fume separator, where fumes enter through an S-shaped inlet and exit through an outlet. However, this type of fume separator has a flat front and rear plate structure and a vertical baffle strip, resulting in a limited air intake area and easy escape of fumes, leading to poor fume separation. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art.

[0004] A first aspect of this application provides a three-fold separator, comprising a front separation plate and a rear separation plate. The front separation plate includes a front frame and a plurality of first smoke-blocking strips spaced apart on the front frame, with a smoke inlet between adjacent two first smoke-blocking strips. The rear separation plate includes a rear frame and a plurality of second smoke-blocking strips spaced apart on the rear frame, with a smoke outlet between adjacent two second smoke-blocking strips. The smoke inlet and the smoke outlet are connected. The rear separation plate is connected to the front separation plate. A mounting groove is provided on one side of the rear separation plate, and the front separation plate is disposed in the mounting groove. The two ends of the front separation plate and the rear separation plate are folded in the same direction, and the two ends of the front frame, the rear frame, the first smoke-blocking strips, and the second smoke-blocking strips are folded correspondingly.

[0005] The three-fold separator provided in this application has at least the following beneficial effects: on the basis of a flat surface, the total air intake area remains unchanged, but the projected area is reduced, the wind speed is increased, and the oil fume extraction effect is improved. Compared with the previous method of using flat panels for both the front and rear panels, the folding design in this application has a better oil fume separation effect.

[0006] According to some technical solutions of this application, the front separating plate and the rear separating plate are respectively provided with a first folding part, a connecting part, and a second folding part. The first folding part is connected to the second folding part through the connecting part, and the first folding part and the second folding part fold towards the center of the connecting part. Thus, the folding towards the center ensures that the airflow is accelerated, improves the oil fume extraction efficiency, and allows the generated oil fumes to be quickly sucked in and discharged.

[0007] According to some technical solutions of this application, the front separating plate is provided with first contact balls on both sides, and the rear separating plate is provided with a limiting step corresponding to the position of the first contact balls. The first contact balls cooperate with the limiting step to make the front separating plate and the rear separating plate detachably connected. Thus, the first contact balls on both sides of the front separating plate are embedded in the grooves of the limiting step of the rear separating plate, and are fixed by elastic pressure. When disassembling, pulling the first contact balls can unlock the plate, achieving quick disassembly and assembly.

[0008] According to some technical solutions of this application, the bottom of the separating front plate is provided with a positioning post, and the bottom of the separating rear plate is provided with a positioning groove that cooperates with and connects to the positioning post. Thus, the positioning post can be inserted into the positioning groove. By providing the positioning post and the positioning groove, it is ensured that the front and rear plates are aligned and inserted before being fixed by the first contact ball, thereby achieving precise positioning, preventing misalignment during installation, and improving the stability after installation.

[0009] According to some technical solutions of this application, the cross-sections of the first and second smoke-blocking strips are semi-circular. Therefore, by setting the cross-section of the smoke-blocking strips to a semi-circular surface, resistance is reduced and oil droplet accumulation is avoided.

[0010] According to some technical solutions of this application, the semi-circular opening of the first smoke baffle faces the smoke outlet, and the semi-circular opening of the second smoke baffle faces the smoke inlet. Therefore, when the fumes pass through, the airflow generates eddies due to the wavy path, and oil droplets collide with the surface of the smoke baffle, condense, and slide off. The wavy structure improves the collision and condensation effect of the fumes, further enhancing the separation efficiency.

[0011] According to some technical solutions of this application, the first smoke-blocking strip and the second smoke-blocking strip are spaced apart and staggered, and a gap is provided between the first smoke-blocking strip and the second smoke-blocking strip to form an airflow channel. Thus, the airflow channel formed by the staggered arrangement and the gap guides the airflow to rotate, promoting oil droplet separation while maintaining smooth airflow.

[0012] According to some technical solutions of this application, the top of the separation plate is provided with a second contact ball, which is used to connect with the top mounting position of the range hood. The bottom of the separation plate is provided with a protrusion, which is used to connect with the bottom mounting hole of the range hood. Thus, the top of the separator is engaged with the top of the range hood through the second contact ball, and the bottom protrusion is embedded in the bottom mounting hole of the range hood, forming a double fixation from top to bottom, ensuring stable installation and preventing displacement.

[0013] According to some technical solutions of this application, the front panel to be separated is provided with a lifting part, which is integrally formed with the front panel to be separated. Therefore, the front panel can be removed by applying force while holding the lifting part, without the need for additional parts, making the operation convenient.

[0014] A second aspect of this application provides a range hood, including the three-fold separator as described in the above technical solution.

[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0027] The following is combined with Figures 1 to 7 The embodiments of this application are described below.

[0028] Based on the above, this application provides a three-fold separator, which includes a front separation plate and a rear separation plate. The front separation plate 100 includes a front frame and a plurality of first smoke-blocking strips 120 spaced apart on the front frame, with a smoke inlet 130 between two adjacent first smoke-blocking strips 120. The rear separation plate 200 includes a rear frame and a plurality of second smoke-blocking strips 220 spaced apart on the rear frame, with a smoke outlet 230 between two adjacent second smoke-blocking strips 220. The smoke inlet 130 and the smoke outlet 230 are connected. The rear separation plate 200 is connected to the front separation plate 100. A mounting groove is provided on one side of the rear separation plate 200, and the front separation plate 100 is disposed in the mounting groove so that the rear separation plate 200 surrounds the rear of the front frame plate. The two ends of the front separation plate 100 and the rear separation plate 200 are folded in the same direction, and the two ends of the front frame, the rear frame, the first smoke-blocking strips 120, and the second smoke-blocking strips 220 are folded correspondingly.

[0029] By using a folding design at both ends, the projected area of ​​the three-fold separator is reduced while maintaining the same total air intake area on a flat surface. This increases the airflow speed, improves the air intake efficiency of the separator, and enhances the fume extraction effect. Compared to the previous design where both the front and rear panels were flat, the folding design in this application results in better fume separation.

[0030] In some embodiments, the front panel 100 and the rear panel 200 are respectively provided with a first folding portion 101, a connecting portion 102, and a second folding portion 103. The first folding portion 101 is connected by the connecting portion 102 and the second folding portion 103. The first folding portion 101 and the second folding portion 103 are folded toward the center of the connecting portion 102, such that the first folding portion 101 and the second folding portion 103 are inclined relative to the connecting portion 102. Optionally, as... Figure 2As shown, the first folding part 101 and the connecting part 102 form a first included angle α, and the second folding part 103 and the connecting part 102 form a second included angle β. The angles of the first included angle and the second included angle may be the same or different. Alternatively, the angles of the first included angle and the second included angle may be greater than 90° and less than 180°. More preferably, the first included angle and the second included angle are greater than or equal to 105° and less than or equal to 135°, respectively, to prevent the angles of the first included angle and the second included angle from being too small or too large, which would lead to a deterioration in the separation effect of the separator on grease.

[0031] In some embodiments, the front separating plate 100 is provided with first abutment beads 140 on both sides, and the rear separating plate 200 is provided with a limiting step 240 corresponding to the position of the first abutment beads 140. The first abutment beads 140 cooperate with the limiting step 240 to make the front separating plate 100 and the rear separating plate 200 detachably connected. Specifically, the first abutment beads 140 includes an abutment bead structure composed of a bead body, a spring, and a housing. The housing is used to accommodate the spring and the bead body. When the front separating plate 100 and the rear separating plate 200 are installed, the front separating plate 100 is brought close to the rear separating plate 200, so that the first abutment beads 140 on both sides of the front separating plate 100 are aligned with the limiting step 240 on the rear separating plate 200. When the two are close enough, an appropriate pressure is applied to the front separating plate 100. The first abutment beads 140 are squeezed by the inner wall on the side where the limiting step 240 is located, and the spring inside is compressed, and the bead body retracts a certain distance. As pressure is continuously applied, when the bead moves to the position of the limiting step 240, the spring returns to its elasticity, pushing the bead out and locking it into the limiting step 240, thus achieving a tight connection between the front separation plate 100 and the rear separation plate 200. Optionally, a corresponding limiting hole can be provided at the limiting step 240 to make the connection even tighter after locking. In addition, when disassembly is required, an outward pulling force is applied to the front separation plate 100, causing the first contact bead 140 to be compressed again. The spring is compressed, and the contact bead disengages from the limiting step 240, thus making it easy to separate the front separation plate 100 from the rear separation plate 200. This eliminates the need to remove the entire separator from the range hood each time for cleaning or maintenance.

[0032] To ensure the stability of the connection between the front separation plate 100 and the rear separation plate 200, in some embodiments, the front separation plate 100 is provided with a positioning post 150 at its bottom, and the rear separation plate 200 is provided with a positioning groove 250 corresponding to the positioning post 150 at its bottom. The positioning post 150 can be inserted into the positioning groove 250. When installing the front separation plate 100 and the rear separation plate 200, the front separation plate 100 is first inserted into the bottom of the rear separation plate 200 at a certain angle between the two, that is, the positioning post 150 at the bottom of the front separation plate 100 is first inserted into the positioning groove 250 at the bottom of the rear separation plate 200. Then, the first abutment balls 140 on both sides are engaged in the limiting step 240 to further fix the relative position of the two and enhance the stability of the connection between the front separation plate 100 and the rear separation plate 200. In this way, the front separation plate 100 can be easily disassembled separately to clean the front separation plate 100 or the inside of the separator, remove oil and impurities, and restore the performance of the separator. Furthermore, if a component of the separator is damaged, that component can be replaced individually, reducing maintenance costs.

[0033] To improve the quality of oil fume separation, in some embodiments, the cross-sections of the first smoke-blocking bar 120 and the second smoke-blocking bar 220 are semi-circular. Further, as... Figure 4 As shown, the semi-circular opening of the first smoke baffle 120 faces the smoke outlet 230, and the semi-circular opening of the second smoke baffle 220 faces the smoke inlet 130, so that the airflow forms a wave-like structure. When the fumes flow within the separator, they continuously change direction along the wave-like channel. Noise needs to undergo more reflections to be reduced. When the fumes encounter the wave-like protrusions, they are forced to change direction. During this continuous change of direction, oil droplets and particles in the fumes are more likely to collide with and adhere to the surface of the smoke baffle due to inertia.

[0034] To increase the contact area and contact time between the fumes and the smoke-blocking strips, in some embodiments, the first smoke-blocking strip 120 and the second smoke-blocking strip 220 are spaced apart and staggered, with gaps between them to form a tortuous airflow channel. After entering these channels, the fumes continuously collide with and detour around the smoke-blocking strips. When the fumes encounter the first smoke-blocking strip 120, part of the airflow is blocked and changes direction, bypassing the first smoke-blocking strip 120 before encountering the second smoke-blocking strip 220 again, resulting in further collisions and detours. During this process, oil droplets and particles in the fumes are impacted and collided with by the airflow. Because oil droplets and particles have a large mass and inertia, they are more likely to deviate from the direction of the airflow and contact and adhere to the surface of the smoke-blocking strips, allowing more oil droplets to separate from the fumes and improving the fume separation effect.

[0035] To facilitate the connection between the separator and the range hood, in some embodiments, the top of the separator rear plate 200 is provided with a second contact ball 260, and the range hood has a mounting position corresponding to the second contact ball 260, which is used to connect with the mounting position on the range hood. The bottom of the separator rear plate 200 is provided with a protrusion 270, which is used to connect with the bottom mounting hole of the range hood. In practice, when installing the separator onto the range hood, the protrusion 270 at the bottom of the separator rear plate 200 is aligned with the bottom mounting hole of the range hood. Then, the separator is slowly lowered so that the protrusion 270 is inserted into the bottom mounting hole. There is an interference fit or locking structure between the protrusion 270 and the bottom mounting hole of the range hood, which allows the separator to be tightly connected to the bottom of the range hood after insertion. After completing the bottom connection, the second contact ball 260 at the top of the separator rear plate 200 is aligned with the top mounting position of the range hood. As the two come close, an inward force continues to be applied to the separator, and the second contact ball 260 is squeezed by the inner wall of the top mounting position edge, compressing the internal spring and retracting the contact ball. When the separator moves to the mounting position, the spring returns to its elasticity, pushing the contact ball out and locking it into the top mounting position, thereby achieving a fixed connection between the separator and the range hood.

[0036] In some embodiments, the front panel 100 is provided with a lifting part 160. When disassembling the separator or the front panel 100, simply grasp the lifting part 160 on the front panel 100 and pull it upwards or outwards to unlock the corresponding locking structure. Optionally, the lifting part 160 is integrally formed with the front panel 100. Since the lifting part 160 is integrally formed with the front panel 100, it has high structural strength. The separator can also be removed from the range hood as a whole by using the lifting part 160, making the disassembly and installation process of the separator easier and more convenient.

[0037] This application also provides a range hood, including the three-section separator of the above-described technical solution. The number of separators can be determined according to requirements. For example, such as... Figure 7 The illustrated range hood structure includes two three-fold separators. By simply creating corresponding mounting positions and holes on the range hood and aligning the corresponding structures on the separators, quick assembly and disassembly with a secure connection can be achieved. Furthermore, it possesses some or all of the beneficial effects of the aforementioned separator, which can be understood by those skilled in the art based on the above technical solution, and will not be elaborated further here.
