Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a filter screen and an integrated stove. Background Art

[0002] The filter is a barrier that filters oil fumes at the smoke inlet of the integrated stove. When the oil fume passes through the filter, it contacts, rubs, and condenses with the mesh holes. The oil and water vapor in the oil fume will be separated at the filter. The lighter smoke after filtration will be discharged through the air duct. The regularly arranged mesh holes have a certain rectification and noise reduction effect on the airflow.

[0003] There are two main types of smoke inlets for existing integrated stoves, one without a filter and the other with a filter. The integrated stove without a filter has low air intake resistance and high air intake efficiency, but poor oil fume separation effect, while the integrated stove with a filter has good oil fume separation effect, but high air intake resistance and low air intake efficiency. Therefore, these two types cannot take into account both oil fume separation effect and air intake efficiency at the same time.

[0004] Therefore, it is urgent to design a filter screen and an integrated stove to solve the above-mentioned technical problems. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0039] like Figure 1 As shown, this embodiment provides an integrated stove, which includes a body, a stove assembly and a fume exhaust device. The stove assembly is arranged on the body, and the fume exhaust device includes a fume hood 200 connected to the body at the upper rear of the body and a fan installed in the body. The fume hood 200 is arranged above the stove assembly, and a smoke baffle 300 is arranged on the front of the fume hood 200. The fume hood 200 is provided with a smoke inlet, and the smoke baffle 300 is used to open or close the smoke inlet. The integrated stove also includes a filter 100, which is installed at the smoke inlet. When the filter 100 is installed, it contacts and cooperates with the fume hood 200 and the smoke baffle 300.

[0040] In order to reduce the intake resistance and improve the intake efficiency, such as Figure 2 and Figure 3 As shown, three mounting seats 201 are provided at intervals at the smoke inlet of the smoke hood 200 in this embodiment, and the mounting seats 201 are used to install and support the filter 100. Compared with the installation method of the flat oil mesh flange 201' in the prior art, the air inlet cross-sectional area of ​​the mounting structure is significantly larger than that of the flat oil mesh flange 201', thereby improving the air intake efficiency. Exemplarily, in this embodiment, a mounting seat 201 is provided at the left end, middle end and right end of the smoke inlet, respectively, and the distance between the middle mounting seat 201 and the mounting seats 201 at the left and right ends is equal, and its air inlet cross-sectional area is calculated to be 59895mm 3 If the same smoke inlet is a flat oil screen flange 201' installation structure, the air inlet cross-sectional area is calculated to be 48523mm 3 It can be seen that the air inlet cross-sectional area of ​​the installation structure in this embodiment is increased by about 23%. The air inlet cross-sectional area is increased, the air inlet resistance is reduced, and the air inlet efficiency is improved.

[0041] like Figures 3 to 6As shown, the filter 100 in this embodiment includes a filter body 101, on which regularly arranged smoke meshes 3 are provided, the filter body 101 is recessed toward the inside of the smoke inlet, and the cross-sectional shape of the filter body 101 is an asymmetric V-shaped structure. When the oil smoke passes through the filter 100, it contacts, rubs, and condenses with the smoke mesh 3, and the oil and water vapor in the oil smoke will be separated at the filter 100. After filtering, the lighter smoke will be discharged through the air duct, and the regularly arranged smoke meshes 3 have the effect of rectifying and reducing noise. The filter body 101 is recessed toward the inside of the smoke inlet, which helps to increase the contact area between the oil smoke and the filter body 101, and by increasing the probability of the oil in the oil smoke colliding with the filter body 101, the probability of the filter 100 capturing the oil is increased, thereby improving the oil separation effect of the filter 100.

[0042] The cross-sectional shape of the filter body 101 is an asymmetric V-shaped structure. Since there is a wall attachment effect when air flows through the surface of an object, the V-shaped structure has an air intake contact area that is about 14% higher than that of a plane structure, thereby reducing the air intake resistance and improving the air intake efficiency. In addition, the structural strength of the V-shaped structure is better than that of a plane structure. The asymmetric V-shaped structure makes the filter body 101 present a partial V-shaped structure, that is, the two sides of the V-shaped structure are of different lengths. Through the design of the long and short sides, the filter 100 can be installed flush with the upper surface of the smoke hood 200, such as Figure 4 As shown, visually, it is still a flat filter 100, making the appearance more regular and beautiful. At the same time, the filter 100 with a V-shaped cross-section has a better effect on the extraction of separated grease. The oil particles attached to the filter can quickly gather at the bottom of the filter 100 under the slope of the V-shaped filter 100, and finally drip through the bottom of the filter 100. Therefore, by setting the filter 100 with a V-shaped cross-section, the grease extraction efficiency can be accelerated while increasing the contact area between the oil smoke and the filter 100, avoiding a large amount of grease from accumulating on the filter 100 to form oil scale and affecting the permeability of the filter 100, thereby achieving the purpose of taking into account both the oil smoke separation efficiency and the air intake efficiency.

[0043] It should be noted that the “cross section” mentioned here refers to the cross section perpendicular to the length direction of the filter body 101 .

[0044] Specifically, if Figure 5 and Figure 6As shown, the filter body 101 includes a first inclined surface 1 and a second inclined surface 2 connected at an angle, and smoke meshes 3 are provided on the first inclined surface 1 and the second inclined surface 2, and the smoke meshes 3 on the first inclined surface 1 correspond to the smoke meshes 3 on the second inclined surface 2. The length of the first inclined surface 1 in the cross section is greater than the length of the second inclined surface 2 in the cross section, so that in the above cross section, the first inclined surface 1 and the second inclined surface 2 form an asymmetric V-shaped structure. The filter 100 adopts this long and short side design, so that after the filter 100 is installed on the whole machine, only the smoke meshes 3 on the long side can be seen visually, avoiding too many lines and irregular appearance, and having a higher aesthetics.

[0045] Furthermore, if Figure 5 As shown, in the above cross section, the angle α between the first inclined plane 1 and the horizontal direction is smaller than the angle β between the second inclined plane 2 and the horizontal direction. The first inclined plane 1 and the second inclined plane 2 form an asymmetric V-shaped structure, and the top angle of the V-shaped structure is biased toward the second inclined plane 2 side.

[0046] Optionally, in the cross section, the angle α between the first inclined plane 1 and the horizontal direction is in the range of 10°≤α≤25°; and / or, in the cross section, the angle β between the second inclined plane 2 and the horizontal direction is in the range of 40°≤β≤60°. Within the above angle range, after the filter 100 is installed on the whole machine, only the mesh on the first inclined plane 1 can be visually seen, and the filter 100 has the visual effect of a flat filter 100, and the appearance lines are regular and uniform. In this embodiment, the angle α between the first inclined plane 1 and the horizontal direction can be 10°, 15°, 20° or 25°, and the angle β between the second inclined plane 2 and the horizontal direction can be 40°, 45°, 50°, 55° or 60°, and the specific values ​​can be selected according to actual conditions.

[0047] In this embodiment, if Figure 6 As shown, the filter 100 also includes a flange 102, one end of which is connected to the peripheral edge of the filter body 101, and the other end extends toward the inner side of the smoke inlet. The filter 100 is an overall curved surface transition V-shaped structure stretch, and its peripheral circle has reverse flanges 102. The combined structure of the curved surface transition V-shaped stretch and the reverse flange 102 has high strength, which solves the problem of low overall strength of the narrow and long oil net.

[0048] In order to realize the convenient disassembly of the filter 100, a handle hole 4 is also provided on the filter body 101. Optionally, a handle hole 4 is respectively provided on the leftmost and rightmost sides of the first slope 1. The existing smoke mesh 3 can be directly used as the handle hole 4, or the existing smoke mesh 3 can be enlarged to a size suitable for finger insertion as the handle hole 4, or the smoke mesh 3 on the left and right sides can be reduced to leave space for the handle hole 4. In this embodiment, the handle hole 4 is preferably opened on the leftmost and rightmost sides of the first slope 1 using the third scheme mentioned above, and the handle hole 4 is integrated with the smoke mesh 3. There is no need to add additional parts to realize the handle function, and the integrity is good and the cost is low. It should be noted that the reason why the handle hole 4 is set on the first slope 1 is that only the first slope 1 is exposed after the filter 100 is installed.

[0049] Since the filter body 101 is an asymmetric V-shaped structure, the upper part of the filter 100 cannot be kept in the same plane after the rounding due to different angles when the model is rounded. Therefore, in order to improve the appearance, the filter body 101 is provided with equidistant areas, such as Figure 7 The filter screen 100 is an appearance part, and the surface needs to be smooth and naturally transitioned. The equidistant areas are connected by curved transitions to form a natural vanishing surface, making the product lines regular and the appearance of the filter screen 100 beautiful and coordinated.

[0050] In this embodiment, if Figure 6 As shown, the filter body 101 is also provided with an oil leakage mesh 5, which connects the first inclined surface 1 and the second inclined surface 2. The first inclined surface 1 and the second inclined surface 2 are connected at the bottom of the filter body 101. Therefore, by providing the oil leakage mesh 5, the oil and water vapor intercepted by the filter 100 and collected at the bottom of the filter body 101 can be discharged to the oil path of the integrated stove.

[0051] Optionally, a plurality of oil leakage meshes 5 are arranged at intervals along the length direction of the filter body 101, and the smoke meshes 3 on the first inclined surface 1 and the corresponding smoke meshes 3 on the second inclined surface 2 are connected to form the oil leakage meshes 5. In this way, the oil leakage meshes 5 are formed by the smoke meshes 3, and no additional oil leakage structure is required, which simplifies the processing technology and reduces the processing cost.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, but may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
