Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art

[0002] Range hoods have become one of the indispensable kitchen appliances in people's daily lives. Range hoods can quickly remove the fumes generated during the user's cooking process, reduce pollution, purify the air, and greatly improve people's quality of life.

[0003] Existing range hoods are usually equipped with a fan, which includes a volute. When the range hood is working, a large amount of oil smoke passes through the volute with the airflow, so that a large amount of oil liquid is retained inside and outside the volute. In order to collect this oil liquid, an oil guide groove is usually provided under the volute. In order to avoid vibration and noise caused by the contact between the oil guide groove and the range hood caused by the shaking of the range hood when working, the end of the oil guide groove that is not connected to the volute is usually designed to be suspended.

[0004] However, there is still some distance between the oil guide groove and the oil cup at the bottom of the range hood. The oil collected in the oil guide groove flows out through the suspended end of the oil guide groove. The oil dripping on the bottom of the range hood will cause uncontrollable splashing, which may not only contaminate other internal structures of the range hood, but also make the cleaning of the range hood more difficult, greatly affecting the user experience. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, the utility model provides a range hood. The range hood includes a chassis, a smoke hood and a volute, the smoke hood is connected to the bottom of the chassis, the volute is arranged in the chassis, the smoke hood has a front plate and a rear plate arranged opposite to each other, and the volute has a shell end arranged away from the rear plate. A first oil guide is connected to the shell end, the first oil guide extends downwardly from the shell end toward the rear plate and has a first end away from the shell end; a second oil guide is connected to the rear plate, the second oil guide extends from the rear plate toward the front plate and has a second end away from the rear plate; wherein an oil leakage hole is arranged on the second oil guide, the projection of the first oil guide toward the plane where the second oil guide is located has an overlapping portion with the second oil guide, and the first end is located above the second end.

[0006] In the range hood provided by the utility model, the first oil guide member can collect the oil retained on the volute, and make the oil drip onto the second oil guide member through the first end of the first oil guide member, and the oil drips to the bottom of the range hood after flowing through the second oil guide member. There can be a height difference between the first oil guide member and the second oil guide member. Compared with the oil dripping directly from the first oil guide member to the bottom of the range hood, the provision of the second oil guide member can prevent excessive oil splashing when the oil drips to the bottom of the range hood, thereby preventing other structures inside the range hood from being contaminated by the splashed oil, and since the oil contamination range is limited, such a range hood can be simpler and more convenient to clean.

[0007] Exemplarily, the first oil guide member includes a first oil guide body and a first connector, the first oil guide body is connected to the shell end through the first connector, and a first oil guide groove is formed on the first oil guide body. The first oil guide groove allows the oil collected on the first oil guide member to converge to the bottom of the first oil guide groove and then slide toward the first end, and ensures that the oil collected by the first oil guide member can flow out from the first end, preventing the oil from flowing out from other parts of the first oil guide member and contaminating the interior of the range hood.

[0008] Exemplarily, the first connecting body includes a first connecting portion and a first fixing portion, the first connecting portion is connected between the first fixing portion and the first oil guiding body, and the first fixing portion is connected to the shell end. The arrangement of the first connecting portion and the first fixing portion enables the first oil guiding member to be more stably connected to the shell end, and is easier to connect to a suitable position on the shell end, and the first oil guiding member is also easier to design into a suitable structure, so that the overall structure can be more reasonable.

[0009] For example, the first oil guide groove has a straight groove bottom. When the oil slides on the straight groove bottom, it is not easy to stagnate in the middle part of the first oil guide groove, thereby avoiding the accumulation and congestion of the oil in the first oil guide groove, and the oil guide effect of the first oil guide member can be better.

[0010] Exemplarily, the angle between the bottom of the groove and the horizontal plane is 7° to 10°. When the range hood is installed, the angle B between the bottom of the groove and the horizontal plane is 7° to 10°, which can ensure that the oil collected by the first oil guide member can slide smoothly to the first end and drip from the first end at a speed that is not too high, thereby avoiding splashing when the oil drips to the second oil guide member.

[0011] Exemplarily, the second oil guide extends upward from the rear plate toward the front plate. The oil collected on the second oil guide can be gathered at the connection between the second oil guide and the rear plate, so that the oil can slide down the second oil guide at a specific position, and the position where the oil slides down from the second oil guide is relatively close to the rear plate. In the process of dripping to the bottom of the smoke hood, the oil can adhere to the rear plate and then slide down to the bottom of the smoke hood, so that splashing can be avoided when the oil reaches the bottom of the smoke hood.

[0012] For example, the oil leakage hole is arranged at the connection between the second oil guide and the rear plate. The oil that slides down from the oil leakage hole can adhere to the rear plate and then slide down to the bottom of the smoke hood when dripping to the bottom of the smoke hood, so as to avoid splashing when the oil reaches the bottom of the smoke hood. In addition, the position and path of the oil that slides down from the oil leakage hole to the bottom of the smoke hood are more controllable, so that the range hood is more convenient to clean.

[0013] Exemplarily, the second oil guide member includes a second oil guide body and a second connector, the second oil guide body is connected to the rear plate via the second connector, and a second oil guide groove is formed on the second oil guide body. The second oil guide groove allows the oil collected on the second oil guide member to be gathered at the bottom of the second oil guide groove and then slide toward the connection portion of the second oil guide member with the rear plate, and ensures that the oil collected by the second oil guide member can flow out from the connection portion of the second oil guide member with the rear plate, thereby preventing the oil from flowing out from other parts of the second oil guide member and contaminating the interior of the range hood.

[0014] For example, the oil leakage hole is arranged on one end of the second oil guide groove near the rear plate. The oil that slides down from the oil leakage hole can adhere to the rear plate and then slide down to the bottom of the smoke hood when dripping to the bottom of the smoke hood, so as to avoid splashing of the oil when it reaches the bottom of the smoke hood. In addition, the position and path of the oil that slides down from the oil leakage hole to the bottom of the smoke hood are more controllable, so that the range hood is more convenient to clean.

[0015] Exemplarily, the height difference between the first end and the second end is 2 cm to 3 cm. The height difference A between the first end and the second end of 2 cm to 3 cm can prevent the oil flowing out of the first oil guide member from splashing when it falls onto the second oil guide member.

[0016] For example, an oil outlet hole is provided at the bottom of the volute, and the projection of the oil outlet hole on the plane where the first oil guide member is located is covered by the first oil guide member. In this way, the first oil guide member collects oil more comprehensively, further preventing the oil not collected by the first oil guide member from directly dripping on the bottom of the smoke hood and causing splashing.

[0017] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

DETAILED DESCRIPTION

[0027] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0028] The utility model provides a range hood 10, see Figure 1The range hood 10 may include a chassis 110, a smoke hood 120 and a volute 130. The smoke hood 120 may be connected to the bottom of the chassis 110. The volute 130 may be arranged in the chassis 110. The smoke hood 120 may have a front plate 121 and a rear plate 122 arranged opposite to each other, and the front plate 121 may be closer to the operator than the rear plate 122. The volute 130 may have a front shell and a rear shell in the form of a ring, and the front shell may be closer to the front plate 121 than the rear shell. The volute 130 may have a connecting shell connected between the front shell and the rear shell, and the connecting shell may be cylindrical, and the accommodating cavity formed by the connecting shell, the front shell and the rear shell may be used to accommodate the fan. The volute 130 may have a shell end 131 arranged away from the rear plate 122. The shell end 131 may be located at the bottom of the front shell, or at a portion of the bottom of the connecting shell close to the front plate 121.

[0029] See also Figure 2 and Figure 3 , a first oil guide member 140 may be connected to the shell end 131, and the first oil guide member 140 may be connected to the shell end 131 in various forms such as welding, clamping or threaded connection. The shell end 131 is located at the bottom of the front shell body of the volute 130, or at the bottom of the connection shell body of the volute 130 near the front plate 121, so the first oil guide member 140 connected to the shell end 131 can collect the oil sliding down from the volute 130. The first oil guide member 140 may extend downwardly from the shell end 131 toward the rear plate 122 and may have a first end 141 away from the shell end 131. Since the first oil guide member 140 extends downwardly from the shell end 131 toward the rear plate 122, the oil collected on the first oil guide member 140 will eventually converge to the first end 141 and flow out from the first end 141.

[0030] The rear plate 122 may be connected to a second oil guide member 150, which may be connected to the rear plate 122 by welding, clamping or threading. The second oil guide member 150 may extend from the rear plate 122 toward the front plate 121 and have a second end 151 away from the rear plate 122. The second oil guide member 150 may be provided with an oil leakage hole 152, which may be a hole-shaped structure of any form, and the oil leakage hole 152 may be provided at any position on the second oil guide member 150. The projection of the first oil guide member 140 toward the plane where the second oil guide member 150 is located has an overlapped portion with the second oil guide member 150, and the first end 141 may be located above the second end 151. In this way, the oil that slides down from the first end 141 of the first oil guide member 140 may fall onto the second oil guide member 150.

[0031] After the range hood 10 is installed and fixed, the second end 151 of the second oil guide member 150 can be higher than the connection between the second oil guide member 150 and the rear plate 122, so that the oil collected on the second oil guide member 150 will converge to the connection between the second oil guide member 150 and the rear plate 122. At this time, preferably, the oil leakage hole 152 can be located at the connection between the second oil guide member 150 and the rear plate 122; the second end 151 of the second oil guide member 150 can also be located at the connection between the second oil guide member 150 and the rear plate 1 22, so the second oil guide member 150 only plays a buffering role for the oil sliding down from the first oil guide member 140, so that the oil sliding down from the first oil guide member 140 first falls into the second oil guide member 150, and then slides to the bottom of the smoke hood 120; the second end 151 of the second oil guide member 150 can also be lower than the connection between the second oil guide member 150 and the rear plate 122, so that the oil collected on the second oil guide member 150 will slide down from the second end 151.

[0032] In the range hood 10 provided by the utility model, the first oil guide member 140 can collect the oil retained on the volute 130, and make the oil drip onto the second oil guide member 150 through the first end 141 of the first oil guide member 140. After flowing through the second oil guide member 150, the oil drips to the bottom of the range hood 10. There can be a height difference between the first oil guide member 140 and the second oil guide member 150. Compared with the oil dripping directly from the first oil guide member 140 to the bottom of the range hood 10, the setting of the second oil guide member 150 can prevent excessive oil splashing when the oil drips to the bottom of the range hood 10, thereby preventing other internal structures of the range hood 10 from being contaminated by the splashed oil. Moreover, since the oil contamination range is limited, such a range hood 10 can be simpler and more convenient to clean.

[0033] In one embodiment of the present invention, see Figure 2 , Figure 3 and Figure 4 , the first oil guide member 140 may include a first oil guide body 142 and a first connector 143. The first oil guide body 142 may be connected to the shell end 131 through the first connector 143, and the first connector 143 may be connected to the shell end 131 through various forms such as welding, clamping or threaded connection. A first oil guide groove 1421 may be formed on the first oil guide body 142, and the first oil guide groove 1421 may be a groove-shaped structure in various forms. For example, the first oil guide body 142 may have a "V"-shaped cross-section as a whole, and the first oil guide groove 1421 may be a "V"-shaped groove. The first oil guide groove 1421 allows the oil collected on the first oil guide member 140 to converge to the bottom of the first oil guide groove 1421 and then slide toward the first end 141, and it can ensure that the oil collected by the first oil guide member 140 can flow out from the first end 141, so as to prevent the oil from flowing out from other parts of the first oil guide member 140 and polluting the interior of the range hood.

[0034] The first connecting body 143 may include a first connecting portion 1431 and a first fixing portion 1432. The first connecting portion 1431 may be connected between the first fixing portion 1432 and the first oil guiding body 142. The first fixing portion 1432 may be connected to the shell end 131. The first fixing portion 1432 may be connected to the shell end 131 in various forms such as welding, clamping or threaded connection. The first fixing portion 1432 may have any form that is easy to connect with the shell end 131. For example, the first fixing portion 1432 may have a threaded hole, and the shell end 131 may have a threaded matching hole at a corresponding position. The first fixing portion 1432 may be connected to the shell end 131 by fasteners passing through the threaded hole and the threaded matching hole. The first connecting portion 1431 may be in any form. By designing the first connecting portion 1431 to a suitable shape and size, the first oil guiding body 142 may be located at a suitable position. For example, when it is desired that the first oil guiding body 142 is closer to the volute 130, the first connecting portion 1431 may be designed to have a smaller height. The arrangement of the first connecting portion 1431 and the first fixing portion 1432 allows the first oil guide member 140 to be more stably connected to the shell end 131 and to be more easily connected to a suitable position on the shell end 131. The first oil guide member 140 is also easy to be designed into a suitable structure, so that the overall structure can be more reasonable.

[0035] The first oil guide groove 1421 may have a linear groove bottom. When the oil slides on the linear groove bottom, it is not easy to stagnate in the middle part of the first oil guide groove 1421, thereby avoiding the accumulation and congestion of the oil in the first oil guide groove 1421, and the oil guiding effect of the first oil guide member 140 can be better.

[0036] See Figure 3 After the range hood 10 is installed and fixed, the angle B between the bottom of the groove and the horizontal plane can be 7° to 10°, for example, 7°, 8°, 9.2° or 10°. When the angle B between the bottom of the groove and the horizontal plane is too large, the oil slides too fast in the first oil guide groove 1421, which may cause uncontrollable splashing when the oil falls on the second oil guide member 150, thereby polluting the interior of the range hood 10; and when the angle B between the bottom of the groove and the horizontal plane is too small, the oil slides too slowly in the first oil guide groove 1421, and there is a possibility that the oil will be retained in the first oil guide groove 1421. When the range hood 10 is installed, the angle B between the bottom of the groove and the horizontal plane is 7° to 10°, which can ensure that the oil collected by the first oil guide member 140 can slide smoothly to the first end 141 and the speed of dripping from the first end 141 will not be too large, thereby avoiding splashing when the oil drips to the second oil guide member 150.

[0037] In one embodiment of the present invention, see Figure 2 , Figure 3 and Figure 5 , the second oil guide member 150 may extend upward from the rear plate 122 toward the front plate 121. The oil collected on the second oil guide member 150 may converge at the connection between the second oil guide member 150 and the rear plate 122, so that the oil may slide down the second oil guide member 150 at a specific position, and the position where the oil slides down from the second oil guide member 150 is relatively close to the rear plate 122. In the process of dripping to the bottom of the smoke hood 120, the oil may adhere to the rear plate 122 and then slide down to the bottom of the smoke hood 120, so that splashing of the oil when it reaches the bottom of the smoke hood 120 can be avoided.

[0038] Furthermore, the oil leakage hole 152 can be provided at the connection between the second oil guide 150 and the rear plate 122. The oil can gather at the connection between the second oil guide 150 and the rear plate 122, and slide down from the oil leakage hole 152 at the connection between the second oil guide 150 and the rear plate 122. The oil sliding down from the oil leakage hole 152 can adhere to the rear plate 122 and then slide down to the bottom of the smoke hood 120 during the process of dripping to the bottom of the smoke hood 120, so that splashing of the oil can be avoided when the oil reaches the bottom of the smoke hood 120. In addition, the oil slides down from the oil leakage hole 152, and the position and path of the oil sliding down to the bottom of the smoke hood 120 are more controllable, so that the range hood is more convenient to clean.

[0039] The second oil guide member 150 may include a second oil guide body 153 and a second connector 154. The second oil guide body 153 may be connected to the rear plate 122 via the second connector 154. The second connector 154 may be connected to the rear plate 122 via welding, clamping, or threaded connection. A second oil guide groove 1531 may be formed on the second oil guide body 153. The second oil guide groove 1531 may be a groove-like structure in various forms. For example, the second oil guide body 153 may have a "V"-shaped cross section as a whole, and the second oil guide groove 1531 may be a "V"-shaped groove. The second oil guide groove 1531 allows the oil collected on the second oil guide member 150 to gather at the bottom of the second oil guide groove 1531 and then slide toward the connection between the second oil guide member 150 and the rear plate 122. It can also ensure that the oil collected by the second oil guide member 150 can flow out from the connection between the second oil guide member 150 and the rear plate 122, thereby preventing the oil from flowing out from other parts of the second oil guide member 150 and contaminating the interior of the range hood.

[0040] The oil leakage hole 152 can be set on the second oil guide groove 1531 near one end of the rear plate 122. The oil collected by the second oil guide member 150 can be gathered at the bottom of the second oil guide groove 1531, and slide along the bottom of the second oil guide groove 1531 toward the rear plate 122, and finally flow out at the oil leakage hole 152. The oil that slides down from the oil leakage hole 152 can adhere to the rear plate 122 and then slide down to the bottom of the smoke hood 120 during the process of dripping to the bottom of the smoke hood 120, so as to avoid splashing when the oil reaches the bottom of the smoke hood 120. In addition, the oil slides down from the oil leakage hole 152, and the position and path of the oil sliding to the bottom of the smoke hood 120 are more controllable, so such a range hood is more convenient to clean.

[0041] In one embodiment of the present invention, see Figure 2 and Figure 3 The height difference A between the first end 141 and the second end 151 can be 2 cm to 3 cm, for example, 2 cm, 2.2 cm, 2.7 cm or 3 cm. The height difference A between the first end 141 and the second end 151 is 2 cm to 3 cm, which can prevent the oil flowing out of the first oil guide member 140 from splashing when it falls on the second oil guide member 150.

[0042] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 3 The bottom of the volute 130 may be provided with an oil outlet 132, and the projection of the oil outlet 132 on the plane where the first oil guide 140 is located may be covered by the first oil guide 140. After the range hood 10 is installed and fixed, a large amount of oil may accumulate in the volute 130 during use. The oil in the volute 130 may slide to the bottom of the inner wall of the volute 130 under the action of gravity, and when the bottom of the volute 130 is provided with an oil outlet 132, this part of the oil may flow out from the oil outlet 132. Since the projection of the oil outlet 132 on the plane where the first oil guide member 140 is located is covered by the first oil guide member 140, the oil flowing out of the oil outlet 132 can be collected by the first oil guide member 140, so that the first oil guide member 140 can not only collect the oil sliding down the outer wall of the volute 130, but also collect the oil sliding down the inside of the volute 130. In this way, the first oil guide member 140 collects the oil more comprehensively, further preventing the oil not collected by the first oil guide member 140 from directly dripping on the bottom of the smoke hood 120 and causing splashing.
