[0065] Embodiment 1

[0066] like Figure 1 As shown, the embodiment of the present disclosure provides an oil fume treatment device 100, which can be all types of devices with oil fume treatment function, such as a ceiling-mounted range hood, a side-suction range hood, a top-suction range hood, etc. All types of devices with oil fume treatment function are within the protection scope of the embodiment of the present disclosure. The embodiment of the present disclosure takes the ceiling-mounted range hood as an example to illustrate the structure of the oil fume treatment device 100.

[0067] like Figure 1 and Figure 2 As shown, the oil fume treatment device 100 includes a fan chassis 20, a smoke collection system 10 and a pipeline assembly 30. The fan chassis 20 includes a chassis body 21 and a fan 22 arranged therein. The chassis body 21 and the pipeline assembly 30 are arranged in the front-to-back direction. The chassis body 21 is connected to one end of the pipeline assembly 30 through an air inlet 2111, and the other end of the pipeline assembly 30 is connected to the smoke collection system 10. Figure 1 and Figure 2 As shown, the fan 22 can generate negative pressure, and the negative pressure can make the oil smoke in the cooking area 400 pass through the smoke collection system 10, the pipeline assembly 30 and the chassis body 21 in sequence and then be discharged to the outside.

[0068] like Figure 1 As shown, the chassis body 21 is disposed above the ceiling 300, and the chassis body 21 is detachably connected to the top wall 200. The chassis body 21 is disposed above the ceiling 300, and is far away from the residents. The ceiling 300 can isolate the noise during the operation of the chassis body 21, reduce the impact of the noise on the residents, and improve the user experience. When the height of the wall 200 is different, the working reliability of the oil fume treatment device 100 is ensured by adjusting the length of the pipeline assembly 30. Specifically, Figure 1 and Figure 2 As shown, the pipeline assembly 30 includes a connecting pipe body 31, a flexible pipe body 32 and a rigid pipe body 33 which are connected in sequence, the connecting pipe body 31 is connected to the chassis body 21, and the rigid pipe body 33 is connected to the smoke collection system 10. Among them, the flexible pipe body 32 is a pipe body with a retractable length to adjust the overall length of the pipeline assembly 30. Among them, the connecting pipe body 31 and the rigid pipe body 33 can be rigid connection joints, so that the pipeline assembly 30 can be firmly connected to the chassis body 21 and the smoke collection system 10 respectively.

[0069] like Figure 1 As shown, the smoke collection system 10 includes a smoke collection system body 11 and a flap 12, wherein a smoke inlet 111 is opened on the smoke collection system body 11, and the flap 12 is arranged on the smoke collection system body 11, and the flap 12 can switch between a first state of opening the smoke inlet 111 and a second state of closing the smoke inlet 111.

[0070] It should be noted that if Figure 2As shown, the fan 22 includes a volute 221 and an impeller 222 disposed therein, wherein the volute 221 is provided with an air inlet 2211. The fan 22 of the disclosed embodiment is a double-inlet fan, and the fan 22 has two air inlets 2211, and the two air inlets 2211 are arranged at intervals in the up-down direction. The double-inlet fan has a larger air intake volume, and the oil fume treatment device 100 has a better oil fume absorption effect. Of course, in other embodiments, the fan 22 may also include only one air inlet 2211, or may include three air inlets 2211, four air inlets 2211, or more air inlets 2211. The air intake volume of the fan 22 is increased by providing more air inlets 2211, thereby improving the oil fume absorption effect of the oil fume treatment device 100. Figure 2 As shown, the fan 22 further includes a motor assembly 223 , and the motor assembly 223 can drive the impeller 222 to rotate, thereby realizing the operation of the fan 22 .

[0071] like Figure 2 As shown, the volute 221 includes a first end face 2214, a second end face 2215 and a connecting circumferential surface 2216. The first end face 2214 and the second end face 2215 are arranged at intervals in the up and down directions. The connecting circumferential surface 2216 is arranged between the first end face 2214 and the second end face 2215, and the connecting circumferential surface 2216 is arranged around the outer periphery of the first end face 2214 and the second end face 2215. The first end face 2214, the second end face 2215 and the connecting circumferential surface 2216 can form a complete structure of the volute 221.

[0072] like Figure 2 As shown, an air outlet 2113 is provided on the chassis body 21, and the volute 221 has an air outlet end 2213, which is connected to the air outlet 2113. The gas purified by the fan 22 can be discharged from the chassis body 21 to the outside through the air outlet 2113.

[0073] The existing oil fume treatment device has only one air outlet in the chassis body, and the air outlet is located on one side of the chassis body. However, the location of the external pipeline connected to the air outlet is different for each household, resulting in the air outlet being far away from the external pipeline in some households, making the connection between the air outlet and the external pipeline more complicated and inconvenient for the staff to connect the air outlet with the external pipeline. In addition, the space between some suspended ceilings and walls is narrow, making it impossible to set up additional large-volume connecting pipelines, resulting in the failure of the oil fume treatment device to be installed in some households.

[0074] To solve the above problems, Figure 3 and Figure 4As shown, the chassis body 21 has at least two air outlets 2113, the volute 221 has an air outlet end 2213, and the position of at least part of the fan 22 relative to the chassis body 21 is adjustable so that the air outlet end 2213 can be selectively connected to any air outlet 2113. The air outlet 2113 connected to the air outlet end 2213 can be selected according to the position of the external pipeline in different households, ensuring that the selected air outlet 2113 is relatively close to the external pipeline in the household, and the air outlet 2113 can be connected to the external pipeline through a simple and short connecting pipeline, which is convenient for the operation of the staff and realizes the air outlet 2113 in a narrow space (such as Figure 1 The space between the ceiling 300 and the wall 200 shown in the figure is connected with the external pipeline to ensure the smooth installation of the oil fume treatment device 100 in the resident's home.

[0075] Exemplarily, the air outlet 2213 may be Figure 3 The first installation state connected to the air outlet 2113 on the left side is switched to Figure 4 The second installation state shown is connected to the air outlet 2113 on the right side.

[0076] It should be noted that other air outlets 2113 that are not connected to the air outlet end 2213 can be blocked by a baffle (not shown in the figure) to ensure that the gas purified by the fan 22 is discharged from only one air outlet 2113.

[0077] like Figure 3 and Figure 4 As shown, the motor assembly 223 is fixedly disposed on the chassis body 21, and the impeller 222 has a rotation axis L C The volute 221 has two air inlets 2211, and the two air inlets 2211 are arranged along the rotation axis L C The volute 221 and the motor assembly 223 are coaxially arranged in the extension direction, and the relative position of the volute 221 and the motor assembly 223 is adjustable, so that the motor assembly 223 is set at one of the air inlets 2211, and the air outlet 2213 is connected to the corresponding air outlet 2113. Only by adjusting the relative position of the volute 221 and the chassis body 21, without driving the heavier motor assembly 223 to adjust together, the air outlet 2213 can be quickly connected with the corresponding air outlet 2113, and the fan chassis 20 can be quickly switched to different installation modes, which is convenient for the staff to quickly install the fan chassis 20. In addition, the motor assembly 223 can always be installed on the chassis body 21 more firmly, avoiding damage to the motor assembly 223, and ensuring that the motor assembly 223 is always in good use.

[0078] The fan used in the existing range hood is a centrifugal fan. Since the volute of the centrifugal fan is a spiral structure, the air intake distribution of the fan's air inlet is uneven. Different placement methods of the fan will affect the fan's air intake volume and the range hood's oil fume extraction effect. When the fan is arranged in some ways, the fan's air intake volume will be poor and the range hood's oil fume extraction effect will be poor.

[0079] To solve the above problems, Figure 5 to Figure 7 As shown, the air intake volume of the air intake area of ​​the air inlet 2211 near the first side E1 of the air outlet 2113 is the largest. In order to solve the problem that the air intake volume of the fan is poor and the range hood has a poor oil fume absorbing effect, as shown in FIG. Figure 5 to Figure 7 As shown, for the rotation axis L C The installation method of the fan 22 which is set at an angle with the front-to-back direction is such that the first side E1 of the air inlet 2211 close to the air outlet 2113 is arranged closer to the air inlet 2111 along the front-to-back direction than the second side E2 of the air inlet 2211 far from the air outlet 2113. The air inlet area with the largest air volume can be arranged close to the air inlet 2111, which is beneficial to the air flow of the air inlet 2111 and ensures the aerodynamic performance of the whole machine. The air intake volume of the fan 22 can be increased, thereby effectively improving the oil fume absorption effect of the oil fume treatment device 100.

[0080] like Figure 3 and Figure 4 As shown, the volute 221 can be turned relative to the motor assembly 223, that is, Figure 3 After the volute 221 in the embodiment is removed, it is turned over 180°, and then the turned volute 221 is installed to the Figure 4 The state shown in the figure can ensure that the volute 221 is designed and installed in this way. Figure 3 and Figure 4 The volute 221 shown can always achieve: the air inlet 2211 is closer to the first side E1 of the air outlet 2113 than the air inlet 2211 is far away from the second side E2 of the air outlet 2113 and is arranged closer to the air inlet 2111 in the front-to-back direction. That is to say, through the volute 221 design and installation switching mode of the aforementioned method, the volute 221 of the fan chassis 20 does not need to be provided with two sets of symmetrical shapes for alternating use, which effectively reduces the number of parts of the fan chassis 20 and reduces the manufacturing cost of the fan chassis 20.

[0081] Of course, the volute 221 can also be rotated relative to the motor assembly 223 around the rotation axis L C By rotating, the volute 221 can be quickly switched between different installation modes without completely removing the volute 221, which can effectively improve the installation and switching efficiency of the fan chassis 20.

[0082] like Figure 3As shown, the first diameter D1 of the air inlet 2211 is greater than or equal to the second diameter D2 of the outer contour circle C of the impeller 222, which can facilitate the staff to remove the volute 221 from the fan 22 and then switch the installation state, and can realize the rapid switching of the installation mode of the volute 221.

[0083] When the motor assembly 223 is disposed at one of the air inlets 2211, the motor assembly 223 and the volute 221 are matched with each other in a concave-convex manner, thereby achieving a good sealing effect at the connection position between the motor assembly 223 and the volute 221, and ensuring a good air intake effect of the oil smoke from the air inlet 2211. In addition, the noise generated by the fan 22 during use due to the gap at the connection position between the motor assembly 223 and the volute 221 can be avoided, thereby achieving a silent use effect of the oil smoke treatment device 100.

[0084] like Figures 3 to 10 As shown, the chassis body 21 includes a chassis body 211 and a plug-in slot structure 212 disposed therein, the plug-in slot structure 212 is provided with a plug-in slot 2121, the plug-in slot 2121 has a plug-in interface 2122, the fan 22 has a plug-in flange 2212, the plug-in flange 2212 is plugged into the plug-in slot 2121 through the plug-in interface 2122, and the fan 22 and the chassis body 21 can be quickly and accurately positioned and disassembled through the cooperation of the plug-in flange 2212 and the plug-in slot structure 212. Figure 3 and Figure 4 As shown, the plug interface 2122 can be selectively set upward. On the one hand, it is convenient for the staff to quickly disassemble, assemble and replace the volute 221. On the other hand, when the plug-in flange 2212 is plugged into the plug-in slot structure 212, it can ensure a stable connection between the volute 221 and the chassis body 21.

[0085] Of course, in other optional embodiments, the plug interface can also be set to the left, right, downward, forward, backward, etc. It should be noted that when the plug interface has a downward component direction, an additional fixing structure is required to achieve a fixed connection between the volute and the chassis body, thereby further ensuring a stable connection between the volute and the chassis body.

[0086] like Figure 3 and Figure 4As shown, the motor assembly 223 includes a mounting frame 2231 and a motor 2232. The mounting frame 2231 is connected to the chassis body 21. The motor 2232 is arranged on the mounting frame 2231. The mounting frame 2231 is provided with a vent 22311. The vent 22311 can be connected to the air inlet 2211. That is to say, the volute 221 can also achieve air intake on the side where the motor assembly 223 is arranged, which can effectively increase the air intake of the fan 22 and ensure a good oil fume absorption effect of the oil fume treatment device 100. In addition, the vent 22311 can be connected to the air inlet 2211, so that a good heat dissipation effect of the motor 2232 can be achieved, and the good performance of the motor 2232 during use can be ensured.

[0088] like Figure 3 and Figure 4 As shown, the bracket feet 22314 can be set to two, three, four or more. By setting a large number of bracket feet 22314, the mounting frame 2231 can achieve a more stable supporting effect on the motor assembly 223. Of course, only one larger bracket foot 22314 can be set to ensure a simpler structure of the mounting frame 2231, and the motor assembly 223 has a simple structure, low cost and can be quickly installed with the chassis body 21.

[0089] like Figure 3 and Figure 4 As shown, the chassis body 21 includes an upper box body 2114 and a lower box body 2115, and the upper box body 2114 and the lower box body 2115 are arranged in the up and down direction. The upper box body 2114 and the lower box body 2115 are detachably connected. By removing the lower box body 2115, the fan 22 inside the chassis body 21 can be exposed, which is convenient for the staff to repair the fan 22, and the staff can quickly repair the fan 22.

[0090] Combination Fig. 9 , Fig.11 , Fig.12 and Fig.13 As shown, the upper box body 2114 and the lower box body 2115 can be fixedly connected by at least one of snap-fitting and fixing members 2116, so that a stable connection between the upper box body 2114 and the lower box body 2115 can be achieved.

[0091] like Figure 3 , Figure 4 , Fig.12 and Fig.13 As shown, since the rear sides of the upper box 2114 and the lower box 2115 are arranged against the wall, it is not convenient for the staff to set the fixing member 2116 at the corresponding position. The rear sides of the upper box 2114 and the lower box 2115 can be matched by snapping. Specifically, Fig.13 As shown, the upper box body 2114 includes an upper box body 21141 and a clamping member 21142 disposed thereon, and a clamping groove 21152 is provided on the lower box body 2115. Fig.11 As shown, the clamping member 21142 can be clamped in the clamping groove 21152, thereby achieving a more stable clamping effect between the upper box body 2114 and the lower box body 2115. Fig.11 As shown, the clip 21142 can be provided in plurality. The provision of a plurality of clips 21142 can achieve a stable connection between the upper box body 2114 and the lower box body 2115 .

[0092] like Fig.13 As shown, a protrusion 211422 is provided on the clamp body 211421, and a recessed portion 21153 is provided on the lower box body 2115. When the clamp 21142 is clamped in the clamping groove 21152, the protrusion 211422 and the recessed portion 21153 cooperate with each other, thereby realizing a stable connection between the clamp 21142 and the lower box body 2115.

[0093] It should be noted that if Fig. 9 The fixing parts 2116 shown may be screws, pins, snap-fit ​​assemblies, magnetic assemblies, etc. All fixing parts 2116 that can realize a detachable connection between the upper box body 2114 and the lower box body 2115 are within the protection scope of the embodiments of the present disclosure.

[0094] like Fig.13 As shown, the upper box body 2114 and the lower box body 2115 are plugged in the up-down direction. Through the plug-in cooperation, the upper box body 2114 and the lower box body 2115 can be quickly positioned and quickly assembled.

[0095] like Figure 3 and Figure 4As shown, the motor assembly 223 of the embodiment of the present disclosure is arranged in the lower box body 2115. When the motor assembly 223 needs to be repaired, the motor assembly 223 can be removed together with the lower box body 2115, so that the staff can quickly repair the motor assembly 223.

[0096] like Figure 8 As shown, the volute 221 can be fixedly arranged on the lower box body 2115. When the lower box body 2115 is removed, the volute 221 can also be removed together with the lower box body 2115, so that the staff can quickly switch the installation mode of the volute 221.

[0097] Of course, in other embodiments, the volute can also be fixed to the upper case. When the lower case is removed, the volute remains on the upper case, and the operator does not need to remove the volute, which makes it convenient for the staff to quickly repair the motor assembly.

[0098] like Figure 3 and Figure 8 As shown, the fan chassis 20 also includes a bracket assembly 215, and the bracket assembly 215 may include a first bracket 2151. The first bracket 2151 includes a first mounting plate 21511, a first connecting plate 21512 and a second mounting plate 21513 connected in sequence. The first mounting plate 21511 is fixedly connected to the first end surface 2214 of the volute 221, and the second mounting plate 21513 is fixedly connected to the second end surface 2215 of the volute 221. The first mounting plate 21511 and the second mounting plate 21513 are fixedly connected to the inner wall of the chassis body 21. By setting the first bracket 2151, a stable connection between the volute 221 and the chassis body 21 can be achieved.

[0099] Among them, Figure 8 As shown, the first mounting plate 21511 includes a first horizontal plate 215111, a first vertical plate 215112 and a first reinforcing plate 215113, wherein the first vertical plate 215112 is fixedly connected to the chassis body 21, the first horizontal plate 215111 is fixedly connected to the first vertical plate 215112 and the first end face 2214, respectively, and the first reinforcing plate 215113 is fixedly connected to the first horizontal plate 215111 and the first vertical plate 215112, respectively. By setting the first reinforcing plate 215113, the strength and hardness of the first mounting plate 21511 can be effectively improved, thereby achieving a stable supporting effect of the bracket assembly 215 on the volute 221.

[0100] Similarly, among them, Figure 8As shown, the second mounting plate 21513 includes a second horizontal plate 215131, a second vertical plate 215132 and a second reinforcing plate 215133, wherein the second vertical plate 215132 is fixedly connected to the chassis body 21, the second horizontal plate 215131 is respectively fixedly connected to the second vertical plate 215132 and the second end face 2215, and the second reinforcing plate 215133 is respectively fixedly connected to the second horizontal plate 215131 and the second vertical plate 215132. By setting the second reinforcing plate 215133, the strength and hardness of the second mounting plate 21513 can be effectively improved, thereby achieving a stable supporting effect of the bracket assembly 215 on the volute 221.

[0101] like Figure 3 and Figure 8 As shown, the bracket assembly 215 may include a second bracket 2152 , which is respectively connected to the second end surface 2215 of the volute 221 and the bottom plate 21151 of the chassis body 21 , and the bracket assembly 215 can achieve a stable supporting effect for the volute 221 .

[0102] like Figure 8 As shown, the interior of the second bracket 2152 is hollow, which can achieve a lightweight setting of the second bracket 2152 and effectively reduce the weight of the chassis body 21.

[0103] In addition, if Figure 8 As shown, a through passage is opened inside the second bracket 2152 to prevent the second bracket 2152 from blocking the oil smoke entering the air inlet 2111 on the same side as the second bracket 2152, thereby increasing the air intake of the air inlet 2111 on the same side as the support frame 2152.

[0104] like Figure 8 As shown, the cross-sectional shape of the second bracket 2152 can be a trapezoid with a small top and a large bottom, so as to achieve a stable supporting effect of the second bracket 2152 on the fan 22. Of course, in other optional embodiments, the cross-sectional shape of the second bracket can be other shapes such as a rectangle and a polygon.

[0105] like Figure 2 and Figure 7 As shown, the air inlet 2211 is spaced apart from the inner wall of the chassis body 21 opposite thereto to form an air duct F, and the oil smoke entering from the air inlet 2111 can smoothly enter the interior of the fan 22 through the air duct F. Figure 2 and Figure 7 As shown, the rotation axis L of the fan 22 of the embodiment of the present disclosure C In this case, the fan 22 is arranged horizontally in the chassis body 21. The fan 22 is arranged in this way, so that the size of the chassis body 21 in the vertical direction can be relatively small, thereby ensuring that the fan chassis 20 which is thinner in the vertical direction can be installed in the case Figure 1 The fan 22 is reasonably arranged above the suspended ceiling 300 as shown. This arrangement of the fan 22 is particularly conducive to the installation condition where the space above the suspended ceiling 300 is small.

[0106] like Figure 7 As shown, one of the air inlets 2211 is arranged upward, and the other air inlet 2211 is arranged downward, and each air inlet 2211 is spaced apart from the inner wall of the corresponding volute 221 to form an air duct F. The oil smoke entering from the air inlet 2111 can evenly enter the corresponding air inlet 2211 through the two air ducts F, which is beneficial to the increase of the air intake volume of the fan 22, and can also effectively reduce the noise caused by the uneven air intake volume on both sides of the fan 22, thereby realizing the silent use of the fan 22.

[0107] like Figure 6 to Figure 8 As shown, the first area S1 of the air inlet 2111 is greater than or equal to the sum S2 of the areas of all the air inlets 2211. The oil smoke entering from the air inlet 2111 can provide sufficient air intake for all the air inlets 2211, thereby ensuring that the fan 22 always has sufficient air intake, which is beneficial to the flow of air flow, ensures better aerodynamics of the whole machine, and enables the oil fume treatment device 100 to achieve better absorption and filtering effects on oil smoke.

[0108] like Figure 6 to Figure 8 As shown, the air inlet 2111 is on the horizontal plane H C The projection and the air inlet 2211 are arranged at intervals in the front-to-back direction, and the volute 221 will not block the air inlet 2111, ensuring the circulation of airflow, so that the oil fume treatment device 100 can effectively maintain pressure under the maximum static pressure condition, avoid the oil fume treatment device 100 from releasing pressure under the maximum static pressure condition, and improve the pressure resistance of the oil fume treatment device 100 to the public flue when absorbing oil fume. Even during the peak usage time of the public flue, it can ensure that the oil fume treatment device 100 always has a good absorption effect on oil fume, avoiding oil fume from such Figure 1 The smoke inlet 111 shown overflows to ensure the cleanliness of the kitchen environment.

[0110] like Fig.14 and Fig.15As shown, the embodiment of the present disclosure provides an oil fume treatment device 100, the structure of which is substantially the same as that of the oil fume treatment device 100 of the first embodiment, the main difference between the two being that the chassis body 21 comprises a chassis body 211 and an oil baffle 213, the upper end of the oil baffle 213 is fixedly connected to the inner wall of the chassis body 211, the oil baffle 213 and the chassis body 211 are used to form an oil avoidance space 214, and the fixing member 2116 extends into the inner part of the chassis body 21 It is located in the oil-avoiding space 214. When the oil stains Q flow downward along the inner wall of the chassis body 21 to the oil baffle 213, the oil stains Q can avoid the fixing part 2116 and flow to the bottom plate 21151 of the lower box body 2115 under the obstruction of the oil baffle 213. On the one hand, it can avoid the contamination of the fixing part 2116 by the oil stains Q. On the other hand, it can also avoid the oil stains Q from seeping out of the through hole position of the fixing part 2116, thereby ensuring the overall cleanliness of the oil fume treatment device 100 and the kitchen environment.

Since the upper area of ​​the fan 22 has a larger air intake than the lower area, the upper area of ​​the fan 22 is the main air intake area of ​​the fan 22. The above arrangement can ensure that the upper air inlet 2211 of the fan 22 has sufficient air intake, thereby achieving a better oil fume absorption effect of the oil fume treatment device 100. Among them, the air inlet 2211 can be arranged toward the lower left or the upper right.
