Description

Technical Field

[0001] This utility model relates to the field of kitchenware, and in particular to a 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 separates the oil from the fumes. Therefore, in actual use, the separator easily becomes greasy, and removing the entire separator for cleaning is heavy and inconvenient. CN212362139U discloses a fume separator that requires a complex locking structure to secure the entire separator, making accurate alignment difficult during installation and disassembly complicated during maintenance. Furthermore, in greasy environments, the connecting parts are easily corroded by grease, increasing the difficulty of disassembly and making subsequent maintenance and cleaning troublesome. Utility Model Content

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

[0004] The first aspect of this application provides a 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 flue inlet formed between two adjacent 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 flue outlet formed between two adjacent second smoke-blocking strips. The flue inlet and the flue outlet are connected. A mounting groove is provided on one side of the rear separation plate, and the front separation plate is disposed within the mounting groove. A first contact ball is provided on the front separation plate, and a limiting step is provided on the rear separation plate corresponding to the position of the first contact ball. The first contact ball is inserted into the limiting step to allow the front separation plate and the rear separation plate to be detachably connected.

[0005] The separator provided by this utility model has at least the following beneficial effects: the front plate is inserted into the limiting step of the rear plate by means of a ball bearing on it, and the elastic deformation of the ball bearing is used to achieve locking and fixing. The rigid fit between the ball bearing and the step can ensure connection stability. When disassembling, pressing the ball bearing can unlock the front plate and the rear plate, realizing quick disassembly and assembly, which is convenient for users to clean or replace parts regularly.

[0006] According to some technical solutions of this application, the bottom of the front separation plate is provided with a protrusion, and the bottom of the rear separation plate is provided with a connecting hole that mates with the protrusion, and the protrusion can be inserted into the connecting hole. Thus, during installation, the protrusion at the bottom of the front separation plate is inserted into the connecting hole at the bottom of the rear separation plate to form a preliminary positioning, and then the top is fixed by a ball bearing.

[0007] According to some technical solutions of this application, the cross-sections of the first and second smoke-blocking strips are arc-shaped. Therefore, the arc-shaped structure can extend the oil fume path and improve oil droplet separation efficiency.

[0008] According to some technical solutions of this application, the arc-shaped opening of the first smoke-blocking strip faces the flue outlet, and the arc-shaped opening of the second smoke-blocking strip faces the flue inlet. This increases the contact area between the fumes and the smoke-blocking strip, improving the separation effect.

[0009] The height difference between the top edge of the rear separation plate and the top edge of the front separation plate is 1-3 mm. Therefore, the protruding part acts as a barrier, preventing the collected oil from overflowing and allowing the grease separated from the frame to flow into the range hood's oil collection tray, reducing spillage pollution.

[0010] According to some technical solutions of this application, the flue inlet and the flue outlet are staggered. This allows the oil fumes to form a complex airflow path within the separator, improving the separation effect.

[0011] According to some technical solutions of this application, a lifting part is provided above the front separation plate, and the lifting part is integrally formed with the front separation plate. Therefore, the separation operation of the front and rear plates via the lifting part is convenient, and the structure has high strength and is not easily damaged during use.

[0012] According to some technical solutions of this application, a second contact ball is provided at the top of the rear part of the separator. The second contact ball is used to cooperate and fix with the separator mounting position on the range hood. Thus, the second contact ball can be engaged with the corresponding mounting position on the range hood.

[0013] According to some technical solutions of this application, the bottom of the separated rear plate is provided with a protrusion, which is used to cooperate and fix with the mounting hole at the bottom of the range hood. Thus, the protrusion at the bottom of the separated rear plate is inserted into the mounting hole of the range hood, forming a double fixation with the top bead of the separated rear plate.

[0014] A second aspect of this application provides a range hood including the separator described above.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

Regarding directional descriptions, such as "up," "down," "front," "back," "left," and "right," the directions or positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, 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 this application. In the description of this utility model, unless otherwise expressly limited, terms such as "set," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] The following is combined Figures 1 to 9 The embodiments of this application are described below.

[0030] Based on the above, the first aspect of this application provides a separator, which includes a front separation plate 100 and a rear separation plate 200. The front separation plate 100 includes a front frame and a plurality of first smoke-blocking strips 110 spaced apart on the front frame, with a flue inlet formed between adjacent first smoke-blocking strips 110.

[0031] The rear separation plate 200 includes a rear frame and a plurality of second smoke baffles 210 spaced apart on the rear frame. A flue outlet 220 is formed between two adjacent second smoke baffles 210. The flue inlet and the flue outlet 220 are connected. A mounting groove is provided on one side of the rear separation plate 200. The front separation plate 100 is installed in the mounting groove so that the rear separation plate 200 is arranged around the rear of the front separation plate 100. The fumes enter from the flue inlet 120 formed by the adjacent first smoke baffles 110 on the front separation plate 100, and then are discharged through the flue outlet 220 connected to the flue inlet 120. In this way, the fumes can be guided to flow in an orderly manner and the fumes can be separated.

[0032] See Figure 3 and Figure 5 As shown, a first contact ball 130 is provided on the front separation plate 100, and a limiting step 230 is provided on the rear separation plate 200 at the position corresponding to the first contact ball 130. The first contact ball 130 is inserted into the limiting step 230 so that the front separation plate 100 and the rear separation plate 200 can be detachably connected.

[0033] Specifically, the ball bearings are installed on both sides of the front separating plate 100 and can cooperate with the limiting step 230 on the rear separating plate 200. During installation, the front separating plate 100 and the rear separating plate 200 are aligned and brought close together. The ball bearing is squeezed back by the inner wall of the limiting step 230. When it moves to the limiting step 230, the spring pushes the ball bearing out and locks it into the limiting step 230, thus achieving a fixed connection between the front separating plate 100 and the rear separating plate 200. During disassembly, the front separating plate 100 is pulled to apply a certain external force to compress the ball bearing back, thus separating the front separating plate 100 from the rear separating plate 200. Installation can also be quickly positioned and the operation is convenient. Furthermore, limiting holes can be provided on the limiting step 230 so that the ball bearing can be locked into the limiting holes during installation, further ensuring a tight connection between the front separating plate 100 and the rear separating plate 200.

[0034] Therefore, the elastic deformation of the ball is used to achieve locking and fixing. The rigid fit between the ball and the step can ensure the connection stability of the front plate 100 and the rear plate 200. When disassembling, pressing the ball can unlock the front plate 100 and the rear plate, realizing quick disassembly and assembly, which is convenient for users to clean or replace parts.

[0035] Among them, the ball bearing is a ball bearing structure well known to those skilled in the art. For example, a ball bearing structure consists of a ball, a spring, and a housing. The housing is used to accommodate the spring and the ball. When the ball is squeezed by an external force, the ball is pressed into the housing and the spring is compressed. When the external force disappears, the spring pushes the ball out of the housing and returns to its initial position. The specific principle will not be elaborated here. In actual processing, the number and position of the ball bearings can be selected and adjusted according to the needs of connection stability.

[0036] To further 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 has a protrusion 140 at its bottom, and the rear separation plate 200 has a connecting hole 250 at its bottom that mates with the protrusion 140. The protrusion 140 can be inserted into the connecting hole 250. When installing the front separation plate 100 and the rear separation plate 200, the front separation plate 100 is inserted at a certain angle between the two. The protrusion 140 at the bottom of the front separation plate 100 is first inserted into the connecting hole 250 at the bottom of the rear separation plate 200, and then the first abutment balls 130 on both sides are engaged in the limiting step 230 to further fix the relative position of the two, enhance the stability of the connection between the front separation plate 100 and the rear separation plate 200, and prevent relative displacement between the two during use through the bottom protrusion structure, improve assembly accuracy, disperse mechanical stress, and enhance the overall structural vibration resistance.

[0037] In some embodiments, the first baffle bar 110 and the second baffle bar 210 have arc-shaped cross-sections. After entering from the flue inlet, the fumes flow along the curved surfaces of the first baffle bar 110 and the second baffle bar 210, and after condensation, slide down the arc surface into the oil collection tray of the range hood. Further, as... Figure 7 As shown, the arc-shaped opening of the first baffle 110 faces the flue outlet between the two opposing second baffles, and similarly, the arc-shaped opening of the second baffle 210 faces the flue inlet 120. In this way, the fumes change direction multiple times in the tortuous channel, and oil droplets in the fumes collide and adhere to the surface of the baffles. After condensation, they are guided to the bottom through the wave-like structure, improving the oil-fume separation effect. This reduces the amount of oil entering the range hood and lowers the pollution to other components of the range hood.

[0038] The height difference between the top edge of the rear separating plate 200 and the top edge of the front separating plate 100 is 1-3 mm. This allows the protruding portion to act as a barrier, preventing collected grease from overflowing and directing the grease separated on the frame to flow into the grease collection tray of the range hood. This prevents the grease from overflowing from the separator due to airflow during cooking, thus reducing spillage. Optionally, such as... Figure 9 As shown in the structure, the height difference d between the top edge of the rear separator plate 200 and the top edge of the front separator plate 100 is 3mm. In this way, the protruding end face of the outer separator plate can form a barrier structure, confining the oil contaminant inside the front separator plate 100. When the separator is installed at an angle, it can ensure that the oil contaminant is better guided and collected.

[0039] To further improve the oil fume separation effect, in some embodiments, the flue inlet 120 and the flue outlet 220 are staggered. This staggered inlet and outlet creates a complex airflow path for the oil fumes within the separator, making it easier for oil droplets and gas molecules in the fumes to collide with the internal structure of the separator or other oil droplets. This collision helps the oil droplets coalesce and grow larger, thus making them easier to separate from the airflow.

[0040] In some embodiments, a lifting portion 150 is provided above the separating front plate 100. Exemplarily, the lifting portion 150 can be a lug or a groove. By applying force to the lifting portion 150 above the separating front plate 100, in conjunction with the unlocking action of the ball joint, the separating front plate 100 can be directly lifted upwards for disassembly. Optionally, the lifting portion 150 can be installed at a centrally located position above the separating front plate 100. This ensures that the center of gravity of the separating front plate 100 is evenly distributed on both sides of the lifting handle during lifting, making the lifting process more stable, reducing the possibility of the separator shaking, and facilitating the separation of the separating front plate 100 from the separating rear part. Furthermore, the lifting portion 150 and the separating front plate 100 are integrally die-cast. This not only facilitates operation but also provides high structural strength, making it less prone to damage during actual use.

[0041] In some embodiments, a second contact bead 240 is provided at the top of the separated rear portion, such as... Figure 1 As shown, two second contact beads 240 are provided, located at opposite ends of the top of the rear panel. These second contact beads 240 are used to engage and secure with the separator mounting positions on the range hood. In actual use, the contact beads on the top of the rear panel 200 engage with the slots of the separator mounting positions on the range hood. Pressing the rear panel locks it onto the internal frame of the range hood, achieving a snap-fit ​​connection between the contact beads and the corresponding mounting positions on the range hood. This simplifies the separator installation process and eliminates the need for additional fasteners.

[0042] Furthermore, the bottom of the separation plate 200 is provided with a protrusion 260, which is used to cooperate and fix with the mounting hole at the bottom of the range hood. The protrusion 260 at the bottom of the separation plate 200 is inserted into the mounting hole of the range hood, forming a double fixation with the top bead inside the range hood, preventing the separator from sagging and deforming due to gravity.

[0043] The second aspect of this application provides a range hood, including the separator described in the above technical solution. The separator is installed at the air inlet of the range hood, and the front separator panel 100 can be removed separately from the rear separator without removing the entire separator. Thus, due to the use of the above-mentioned oil fume separator, installation and disassembly are convenient, and the oil fume separation effect of the range hood is significantly improved. This not only reduces the pollution of internal components such as the fan and duct of the range hood by oil, but also extends the service life of the range hood. The modular design reduces maintenance costs, and components can be cleaned or replaced individually during use. The multi-layer separation structure achieves a high grease separation rate, and the snap-fit ​​connection with contact beads also balances lightweight and durability.
