Description

Technical Field

[0001] The present invention relates to the technical field of household kitchen appliances, and in particular to a soot collecting device and a range hood. Background Art

[0002] Smoking is harmful to one's own health, and secondhand smoke harms those around you. Many smokers choose to smoke in the kitchen with the range hood on to protect their families from the harm of secondhand smoke.

[0003] However, because existing range hoods lack ash collection devices, smoking in the kitchen generates a large amount of ash. If the ash is not effectively collected, it will contaminate food and affect health. If an ashtray is placed in the kitchen, smokers will have to carry an ashtray with them when they go to the kitchen to smoke, which is inconvenient. In addition, although running a range hood in the kitchen can remove smoke generated by smoking, the main motor of the range hood is relatively powerful and is only used to extract smoke generated by smoking, which results in a waste of resources. Summary of the Invention

[0004] In order to at least partially solve the problems existing in the prior art, the present invention first provides a soot collecting device.

[0005] The ash collection device provided by the present invention includes a shell, a drawer box and a smoke absorption and purification component; the shell has a first installation cavity and a second installation cavity, the first installation cavity and the second installation cavity are arranged up and down, the first installation cavity has a first port, and the second installation cavity has a first opening and a second opening; the drawer box is slidably connected to the first installation cavity, the drawer box has a pulled-out state and a closed state relative to the shell, and the drawer box has an ash cavity with an open upper part; the smoke absorption and purification component includes a DC fan, an air inlet filter and an air outlet filter, the DC fan is arranged in the second installation cavity, the DC fan has an air inlet side and an air outlet side, the air inlet filter is arranged at the first opening, and the external air is filtered and flows to the air inlet side; the air outlet filter is arranged at the second opening, and the air flowing from the air outlet side is filtered and flows out.

[0006] With the above-mentioned ash collection device, when a smoker smokes, the DC fan of the smoke absorption and purification component can be turned on to purify the smoke; and the drawer box can be pulled out to collect cigarette ash and cigarette butts, and after smoking, the drawer box can be pushed into the first installation cavity to prevent the ash from flying everywhere.

[0007] For example, the inlet filter faces the inlet side, while the outlet filter faces the outlet side. This allows the DC fan to be positioned horizontally (i.e., with the fan axis perpendicular to the inlet or outlet filter). External air is filtered by the inlet filter and flows directly to the inlet side, while air from the outlet side is filtered by the outlet filter and flows out directly, resulting in a simple structure.

[0008] Exemplarily, the housing includes a top wall, side walls, a bottom wall, and a middle wall. The middle wall is located between the top and bottom walls, dividing the side walls into a first side wall and a second side wall. The bottom wall, the first side wall, and the middle wall together form a first mounting cavity. The top wall, the second side wall, and the middle wall together form a second mounting cavity. The middle wall includes an outer wall located outside the second mounting cavity, and the outer wall is provided with a through hole connecting the inside and outside of the first mounting cavity. This provides a simple housing structure and allows for rapid odor removal from the drawer box within the first mounting cavity.

[0009] Exemplarily, the outer shell includes a top wall, a side wall, a bottom wall and a middle wall, the middle wall being located between the top wall and the bottom wall to divide the side wall into a first side wall and a second side wall; the bottom wall, the first side wall and the middle wall enclose a first installation cavity; the top wall, the second side wall and the middle wall enclose a second installation cavity; the DC fan has a side shell connected between the air inlet side and the air outlet side, the side shell includes a first side shell and a second side shell relative to each other, the first side shell is opposite to the air inlet filter, and there is a first gap between the first side shell and the air inlet filter, there is a second gap between the middle wall and the air inlet side, the first gap and the second gap form an air inlet channel connected between the air inlet side and the air inlet filter; the second side shell is opposite to the air outlet filter, and there is a third gap between the second side shell and the air outlet filter, there is a fourth gap between the top wall and the air outlet side, the third gap and the fourth gap form an air outlet channel connected between the air outlet side and the air outlet filter. In this way, the DC fan can be arranged longitudinally (ie, the axis of the DC fan is parallel to the air inlet filter or the air outlet filter), and the entire housing structure is simple.

[0010] For example, a through hole is provided on the middle wall to connect the first installation cavity and the second installation cavity, so that the drawer box in the first installation cavity can quickly dissipate odors through the DC fan.

[0011] For example, the air inlet filter is connected to the housing via screws or a snap-fit structure, so that the air inlet filter can be easily disassembled and assembled for cleaning.

[0012] For example, the air outlet filter is fixedly connected to the housing, or the air outlet filter is integrated with the housing, thereby simplifying the installation process.

[0013] For example, the wall of the first mounting cavity extends a first frame into the first mounting cavity at the first port, and the first frame has a first connecting plane; the wall of the ashtray has a drawer-end sidewall, and the drawer-end sidewall extends toward the periphery of the ashtray to form a second frame, and the second frame has a second connecting plane; when the drawer box is in the closed state, the second connecting plane aligns with the first connecting plane. In this way, after smoking, the smoker can put the cigarette butt into the ashtray, and then push the drawer box into the first mounting cavity so that the second connecting plane aligns with the first connecting plane, isolating the cigarette from outside air, and then automatically extinguishing the cigarette butt, achieving the effect of automatic smoke extinguishing.

[0014] For example, a handle is provided on the side wall of the drawer end, and the handle includes a catch provided on the outer side surface of the drawer end side wall facing away from the ashtray; or a protrusion protruding outwardly on the outer side surface of the drawer end side wall facing away from the ashtray. In this way, the catch or protrusion on the outer side surface facilitates the insertion and removal of the drawer box.

[0015] According to another aspect of the present invention, a range hood is also provided, comprising a body, an air duct and an ash collection device, the air duct being located in the body, the ash collection device being the above-mentioned ash collection device, the outer shell being arranged on the body, the first opening being communicated with the outside of the body, and the second opening being communicated with the air duct.

[0016] Because the aforementioned ash collection device has the aforementioned beneficial effects, a range hood including such a device will inevitably also have the aforementioned beneficial effects. Furthermore, because the range hood includes such a ash collection device, smokers can operate the DC blower of the smoke absorption and purification component while smoking in the kitchen, and exhaust the smoke generated by smoking through the range hood's existing air duct. This eliminates the need to operate the high-power range hood main motor, avoids resource waste, and effectively meets the needs of smokers who smoke in the kitchen to protect their families from the harmful effects of secondhand smoke.

[0017] For example, the range hood includes a range hood control panel, and the DC fan is electrically connected to a switch button disposed on the range hood control panel. Thus, when a smoker smokes in the kitchen, they can operate the switch button on the range hood control panel, which is electrically connected to the DC fan, to expel smoke generated by smoking, thereby facilitating use.

[0018] For example, the housing has a through hole, the housing extends with a flange, the housing passes through the through hole and is located on the inner side of the housing, the flange is located on the outer side of the housing, and the flange is fixedly connected to the housing. In this way, the ash collection device can be mounted on the housing by screws or clips.

[0019] For example, the housing is a part of the body, so that the housing and the body can be integrally formed, thereby simplifying the process.

[0020] The advantages and features of the present invention are described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] In the following description, a large amount of detail is provided to facilitate a thorough understanding of the present invention. However, it will be appreciated by those skilled in the art that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0078] like Figures 1 to 4 As shown, a range hood 100 according to an embodiment of the present invention includes a housing 10, an air duct (not shown), and an ash collection device 20. The ash collection device 20 includes a housing 210, a drawer box 220, and a smoke absorption and purification assembly 230. It should be understood that the air duct is located within the housing 10, and the purified smoke entering the air duct can be discharged outdoors. The air duct is a common structural component of the range hood 100 and will not be described in detail here.

[0079] Housing 210 is mounted on housing 10 and includes a first mounting cavity 2101 and a second mounting cavity 2102. First and second mounting cavities 2101 and 2102 are arranged in an upper and lower arrangement. First mounting cavity 2101 includes a first port 21011, while second mounting cavity 2102 includes a first opening 21021 and a second opening (the second opening is not labeled in the figure; it should be understood that the second opening and the first opening 21021 are located at opposite ends of second mounting cavity 2102). First opening 21021 communicates with the exterior of housing 10, while the second opening communicates with the air duct. First mounting cavity 2101 is used to mount drawer box 220. During installation, drawer box 220 can be inserted into first mounting cavity 2101 through first port 21011. Second mounting cavity 2102 is used to mount flue gas absorption and purification assembly 230.

[0080] The drawer box 220 is connected to the first installation cavity 2101 by sliding. For example, a slide groove is provided in the first installation cavity 2101, and a slide rail connected to the slide groove is provided on the drawer box 220. Through the cooperation between the slide rail and the slide groove, the drawer box 220 can slide relative to the first installation cavity 2101. Of course, the sliding connection method is not limited to this, and examples are not given here. The drawer box 220 has an extracted state and a closed state relative to the housing 210 (such as Figure 1 As shown, the drawer box 220 is in a closed state), and the drawer box 220 has an ash chamber 2201 with an upper opening, the ash chamber 2201 is used to collect cigarette ashes and cigarette butts, and when the smoker smokes, the drawer box 220 can be pulled out from the first installation cavity 2101.

[0081] The smoke absorption and purification component 230 includes a DC fan 231, an air inlet filter 232, and an air outlet filter 233. The DC fan 231 is set in the second installation cavity 2102. The DC fan 231 can be, for example, a 5V axial flow fan, a 12V axial flow fan, or a 24V axial flow fan, preferably a 12V axial flow fan. The DC fan 231 can be fixed to the housing 210 using a snap-fit structure or screws, such as Figure 4 As shown, the DC fan 231 is fixed to the housing 210 by screws 234. The DC fan 231 has an air inlet side 2311 and an air outlet side 2312. When the DC fan 231 is in operation, air is taken in from the air inlet side 2311 and air is discharged from the air outlet side 2312. The air inlet filter 232 is set at the first opening 21021, filtering the external air before it flows to the air inlet side 2311. The air inlet filter 232 can perform preliminary filtration on the smoke entering the DC fan 231, thereby protecting the DC fan 231. The air outlet filter 233 is set at the second opening, filtering the air flowing from the air outlet side 2312 before it flows out. The air outlet filter 233 can filter the smoke coming out of the DC fan 231 again, further purifying the smoke. The smoke purified by the air outlet filter 233 is finally discharged along the air duct.

[0082] The range hood 100 may be a side-suction range hood, a top-suction range hood, or the like.

[0083] Since the above-mentioned range hood 100 is provided with the ash collection device 20, when a smoker smokes in the kitchen, he can turn on the DC fan 231 of the smoke absorption and purification component 230 and use the original air duct of the range hood to discharge the smoke generated by smoking, thereby eliminating the need to turn on the high-power main motor of the range hood 100, thereby avoiding waste of resources; and the drawer box 220 can be pulled out to collect cigarette ash and cigarette butts, and after smoking, the drawer box 220 can be pushed into the first installation cavity 2101, thereby preventing cigarette ash from flying everywhere.

[0084] Figure 4In the illustrated embodiment, the inlet filter 232 faces the inlet side 2311, while the outlet filter 233 faces the outlet side 2312. This allows the DC fan 231 to be positioned horizontally. This horizontal positioning means that the axis AA of the DC fan 231 is perpendicular to the inlet filter 232 or the outlet filter 233. External air, after being filtered by the inlet filter 232, flows directly to the inlet side 2311. Air flowing from the outlet side 2312 is directly filtered by the outlet filter 233 before being discharged, resulting in a simple structure.

[0085] See also Figure 3 and Figure 4 , the shell 210 may have a top wall 212, a side wall 213, a bottom wall 214 and an intermediate wall 215. The intermediate wall 215 is located between the top wall 212 and the bottom wall 214, dividing the side wall 213 into a first side wall 2131 and a second side wall 2132. The bottom wall 214, the first side wall 2131 and the intermediate wall 215 enclose a first installation cavity 2101; the top wall 212, the second side wall 2132 and the intermediate wall 215 enclose a second installation cavity 2102. In this way, the entire shell 210 has a simple structure, and it is convenient to set up the drawer box 220 and the smoke absorption and purification component 230. It should be noted that although Figure 4 In the illustrated embodiment, the second mounting cavity 2102 and the first mounting cavity 2101 are arranged in an upper and lower arrangement. This arrangement of the second mounting cavity 2102 and the first mounting cavity 2101 in an upper and lower arrangement can better meet the requirements of installation on the housing 10. In actual application, the second mounting cavity 2102 and the first mounting cavity 2101 are not limited to an upper and lower arrangement. In embodiments not shown, the first mounting cavity 2101 and the second mounting cavity 2102 can also be arranged in a left and right arrangement. It should be understood that the structure of the housing 210 is not limited to this, as long as the first mounting cavity 2101 for mounting the drawer box 220 and the second mounting cavity 2102 for mounting the smoke absorption and purification assembly 230 are formed.

[0086] Furthermore, because the first mounting cavity 2101 accommodates the drawer box 220 and the second mounting cavity 2102 accommodates the DC fan 231, the DC fan 231 requires less installation space when it is positioned horizontally. Comparatively, the length of the first mounting cavity 2101 is greater than that of the second mounting cavity 2102, meaning that the bottom wall 214 is longer than the top wall 212. In the longitudinal direction, the middle wall 215 includes an outer wall 2151 located outside the second mounting cavity 2102. The outer wall 2151 is provided with a through-hole 21511 connecting the inside and outside of the first mounting cavity 2101. This allows for rapid odor removal from the drawer box 220 within the first mounting cavity 2101. The through-holes 21511 can be multiple, for example, three, six, nine, or so on. Preferably, the diameters of the multiple through-holes 21511 are uniform, and each through-hole 21511 can have a diameter between 3 mm and 6 mm, for example, 3 mm, 4 mm, 5 mm, 6 mm, or so on. The plurality of through holes 21511 ensures that even if one or more of the through holes 21511 are blocked, the other through holes 21511 can still achieve the desired odor removal effect. Furthermore, if the diameter is too large, ash will easily fly out; if the diameter is too small, the odor removal effect will be ineffective.

[0087] Figure 4 In the illustrated embodiment, the DC fan 231 is horizontally arranged, but the arrangement of the DC fan 231 is not limited thereto. The DC fan 231 can also be arranged longitudinally, that is, the axis AA of the DC fan 231 is parallel to the air inlet filter 232 or the air outlet filter 233. The longitudinal arrangement structure of the DC fan 231 is described in detail below.

[0088] like Figure 5As shown, the housing 210 includes a top wall 212, side walls 213, a bottom wall 214, and a middle wall 215. The middle wall 215 is located between the top wall 212 and the bottom wall 214, dividing the side wall 213 into a first side wall 2131 and a second side wall 2132. The bottom wall 214, the first side wall 2131, and the middle wall 215 together form a first installation cavity 2101. The top wall 212, the second side wall 2132, and the middle wall 215 together form a second installation cavity 2102. The DC fan 231 has a side shell connected between the air inlet side 2311 and the air outlet side 2312. The side shell includes a first side shell 2313 and a second side shell 2314. The first side shell 2313 is opposite to the air inlet filter 232, and a first gap 241 is defined between the first side shell 2313 and the air inlet filter 232. A second gap 242 is defined between the middle wall 215 and the air inlet side 2311. The first gap 241 and the second gap 242 form an air inlet channel 24 connected between the air inlet side 2311 and the air inlet filter 232. The second side shell 2314 is opposite to the air outlet filter 233, and a third gap 251 is defined between the second side shell 2314 and the air outlet filter 233. A fourth gap 252 is defined between the top wall 212 and the air outlet side 2312. The third gap 251 and the fourth gap 252 form an air outlet channel 25 connected between the air outlet side 2312 and the air outlet filter 233. In this manner, the DC fan 231 can be arranged longitudinally, and the entire housing 210 has a simple structure. External air is filtered by the air inlet filter 232 and flows through the air inlet channel 24 to the air inlet side 2311. Air flowing in from the air outlet side 2312 passes through the air outlet channel 25 and is then filtered by the air outlet filter 233 before flowing out. Furthermore, the second installation cavity 2102 and the first installation cavity 2101 formed in this manner are arranged in an upper and lower arrangement. This arrangement of the second installation cavity 2102 and the first installation cavity 2101, on the one hand, better meets the requirements for installation on the housing 10; on the other hand, with a through hole provided in the middle wall 215 connecting the first installation cavity 2101 and the second installation cavity 2102, the DC fan 231 can not only draw in external smoke, filter it through the air outlet filter 233, and then discharge it, but can also draw in smoke from within the closed drawer box 220, filter it through the air outlet filter 233, and then discharge it.

[0089] Furthermore, since the first mounting cavity 2101 accommodates the drawer box 220 and the second mounting cavity 2102 accommodates the DC fan 231, a longitudinal arrangement of the DC fan 231 requires a larger installation space. The length of the second mounting cavity 2102 is almost equal to that of the first mounting cavity 2101. This means that the lengths of the bottom wall 214, the top wall 212, and the middle wall 215 can be equal. In this case, to facilitate odor removal from the drawer box 220 when closed, the middle wall 215 can be provided with a through hole connecting the first and second mounting cavities 2101, 2102. The diameter of this through hole can be referred to as through hole 21511. This allows the DC fan 231 to quickly remove odors from the drawer box 220 within the first mounting cavity 2101.

[0090] As an exemplary embodiment, the air inlet filter 232 can be connected to the housing 210 by screws. The screws here can be the screws 234 for fixing the DC fan 231 mentioned above, or they can be other screws. Since screw connection is a common fixing method, it will not be described in detail here. In an embodiment not shown, the air inlet filter 232 can also be fixed to the housing 210 by a snap-fit structure. Since snap-fit structure fixation is a common fixing method, it will not be described in detail here. In this way, with the help of screw fixation or snap-fit structure fixation, the air inlet filter 232 can be easily disassembled and assembled, so that the air inlet filter 232 can be cleaned.

[0091] As an exemplary embodiment, the outlet filter 233 is fixedly connected to the housing 210. For example, the outlet filter 233 is welded to the housing 210. Screws 234 pass through the outlet filter 233, then through the DC fan 231, and then connect to the inlet filter 232. In this way, the screws 234 can simultaneously secure the DC fan 231 and the inlet filter 232, thereby simplifying the installation process. In an embodiment not shown, the outlet filter 233 can also be integrated with the housing 210. This also simplifies the installation process.

[0092] As an exemplary embodiment, the cavity wall of the first installation cavity 2101 extends into the first installation cavity 2101 at the first port 21011 to form a first frame 211, and the first frame 211 has a first connecting plane 2111. Figure 6The cavity wall of the ash chamber 2201 includes a pull-out end side wall 221, an insertion end side wall 222, a cavity bottom wall 223, a cavity left side wall 224 and a cavity right side wall 225. The pull-out end side wall 221, the insertion end side wall 222, the cavity bottom wall 223, the cavity left side wall 224 and the cavity right side wall 225 enclose the ash chamber 2201, and the pull-out end side wall 221 extends to the periphery of the ash chamber 2201 to form a second frame 2211, and the second frame 2211 has a second connecting plane 22111; when the drawer box 220 is in a closed state, the second connecting plane 22111 is in contact with the first connecting plane 2111. In this way, after smoking, the smoker can put the cigarette butt into the ash chamber 2201, and then push the drawer box 220 into the first installation cavity 2101 so that the second connecting plane 22111 fits with the first connecting plane 2111, isolating it from the outside air, and then the cigarette butt is automatically extinguished, achieving the effect of automatic smoke extinguishing.

[0093] See also Figure 4 and Figure 6 To facilitate the user's push-pull operation of the drawer box 220, a handle is provided on the pull-out side wall 221. The handle includes a latch 2260 provided on the outer side surface 22101 of the pull-out side wall 221, which faces away from the ash chamber 2201. Thus, the latch 2260 on the outer side surface 22101 facilitates the insertion and removal of the drawer box 220. Since the latch 2260 is a common structure, it will not be described in detail here.

[0094] like Figure 7 As shown, as another exemplary embodiment of the handle, the outer side 22101 of the pull-out end side wall 221 facing away from the ash chamber 2201 has a protruding portion 2270 protruding outward. In this way, the protruding portion 2270 on the outer side 22101 is provided to facilitate loading and unloading of the drawer box 220.

[0095] It should be understood that the implementation of the handle is not limited to the above-mentioned buckle handle 2260 and protrusion 2270. For example, it can be a hidden handle, a ring handle, etc. Since the handle is a common structure, it will not be described in detail here.

[0096] As an exemplary embodiment, the range hood 100 includes a range hood control panel (not shown). To facilitate on / off control of the DC fan 231, the DC fan 231 is electrically connected to an on / off button (not shown). The on / off button is preferably located on the range hood control panel. This allows smokers to conveniently use the range hood by operating the on / off button on the control panel, which is electrically connected to the DC fan 231. This allows smokers to expel smoke through the DC fan 231, providing convenient operation.

[0097] As an exemplary embodiment, the body 10 has a through hole (not marked in the through hole diagram), the shell 210 extends with a flange 2103, and the shell 210 passes through the inner side of the body 10 (such as Figure 2 As shown in FIG, the flange 2103 is located on the outside of the body 10 and is fixedly connected to the body 10. Specifically, the flange 2103 may have a connection hole, and the body 10 may have a mounting hole. When installing the ash collection device 20, the connection hole and the mounting hole are aligned, and the fixing screws are passed through the connection hole and the mounting hole and tightened. In this way, the ash collection device 20 can be installed on the body 10 using the fixing screws. It should be noted that the "outside" here refers to the side of the body 10 that is exposed to the outside and visible to the user; the "inside" here refers to the side of the body 10 that is not visible to the user.

[0098] The housing 210 can also be secured to the body 10 via a snap-fit structure 30, for example. The snap-fit structure 30 can be a common combination of a through-hole and a buckle. For example, a buckle can be provided on the flange 2103, and a through-hole can be provided on the body 10. When the ash collection device 20 is mounted on the body 10, it is only necessary to insert the buckle into the through-hole. Of course, the form of the snap-fit structure 30 is not limited to this, and examples will not be given here one by one.

[0099] Although the above embodiment shows that the housing 210 is fixedly connected to the body 10, in an embodiment not shown, the housing 210 may also be a part of the body 10. In this way, the housing 210 and the body 10 may be integrally formed, thereby simplifying the process.

[0100] In the above embodiment, the housing 210 and the air inlet filter 232 can be made of sheet metal or flame-retardant plastic, such as flame-retardant ABS or flame-retardant PP, preferably flame-retardant PP. The drawer box 220 can be made of sheet metal or flame-retardant plastic, preferably transparent flame-retardant PC, so that the amount of ash in the drawer box 220 can be easily observed and promptly removed.

[0101] For other components of the range hood 100, such as the main motor, air duct, impeller, etc., various existing or future structures may be adopted. The present invention is not intended to limit them. Therefore, these components will not be described in detail herein.

[0102] It should be noted that although the above embodiment shows that the ash collection device 20 is installed on the range hood 100, in actual use, the ash collection device 20 can also be used separately as an independent component. For a separate ash collection device 20, when the smoker smokes, the DC fan 231 of the smoke absorption and purification component 230 can be turned on to purify the smoke; and the drawer box 220 can be pulled out to collect cigarette ashes and cigarette butts, and after smoking, the drawer box 220 can be pushed into the first installation cavity 2101, which can also prevent the ashes from flying everywhere.

[0103] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "inside", "outside", "upper" and "lower" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words 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 cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0104] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that spatially relative terms include not only the orientation of the components as described in the figures, but also different orientations during use or operation. For example, if the components in the drawings are inverted as a whole, the components "above other components or features" or "above other components or features" will include the situation where the components are "below other components or structures" or "below other components or structures". Therefore, the exemplary term "above" can include both the orientations of "above" and "below". In addition, these components or features can also be positioned at other different angles (for example, rotated 90 degrees or other angles), and this document is intended to include all of these situations.
