[0037] In combination Figure 1 The range hood with fan function includes a fan module 10 and a range hood body 30, the fan module 10 is installed on the range hood body 30, in order to reduce the volume of the entire range hood with fan function, generally need to integrate the fan module 10 and the range hood body 30. Specifically, the range hood body 30 is provided with a check valve 31, the check valve 31 is installed on the shell 100 of the range hood body 30, the check valve 31 is provided with a baffle, which is used to prevent the backflow of oil fume, and avoid the oil fume of the public flue blowing on the range hood body 30. But the check valve 31 blocks part of the air inlet 110, and the filter 20 is easy to interfere with the check valve 31 when installed, which causes the difficulty of installation and disassembly of the filter 20.

[0038] Referring to Figures 1-7 The fan module 10 provided by an embodiment of the present application includes a shell 100, a fan blade and a filter 20. The shell 100 has an air inlet 110 and an air outlet 120, the air inlet 110 includes an installation section 111 and a blocking section 112 arranged along a first direction OX; the fan blade is rotationally arranged in the shell 100, which is used to blow the air entering the air inlet 110 out of the air outlet 120; the filter 20 is installed in the air inlet 110, the filter 20 includes at least two filter screens, the filter screens can be moved from the installation section 111 to the blocking section 112 along the first direction OX.

[0039] In this way, the air inlet 110 includes the installation section 111 and the blocking section 112 arranged along the first direction OX, the blocking position of the check valve 31 is located in the blocking section 112, that is, the installation section 111 is not blocked by the check valve 31. The filter 20 includes at least two filter screens, that is, the filter screens are arranged in sections, so that the filter screens located in the blocking section 112 can be installed in the air inlet 110 through the installation section 111, and then moved from the installation section 111 to the blocking section 112 along the first direction OX, thereby avoiding the interference between the filter screens and the check valve 31 when the filter screens are installed, which causes the difficulty of installation and disassembly of the filter screens.

[0040] The number of installation sections 111 and shielding sections 112 is not limited. When the filter 20 is installed, the range hood body has multiple positions that are prone to interference with the check valve 31, so that the air inlet 110 includes multiple shielding sections 112. The multiple interference positions are all within the range of the shielding sections 112, and the other unshielded positions are the installation sections 111. Specifically, the air inlet 110 includes multiple staggered shielding sections 112 and installation sections 111. Each filter screen enters the air inlet 110 from the installation section 111 and then moves from the installation section 111 to the adjacent shielding section 112.

[0041] For example, if the range hood body has three positions that are prone to interference with the check valve 31, and the three positions are spaced apart from each other, then the air inlet 110 includes three shielding sections 112. The three interference positions are located within the range of the corresponding shielding sections 112, and the other unshielded positions are the installation sections 111.

[0042] In one embodiment of this application, at least two filters include a first filter 21 and a second filter 22, with the first filter 21 located within the shielding section 112 and the second filter 22 located within the mounting section 111.

[0043] The check valve 31 is located within the blocking section 112. When the first filter 21 is installed directly from the blocking section 112, the first filter 21 is prone to interference with the check valve 31. Combined with... Figures 2-4 The first filter 21 is inserted from the installation section 111 into the air inlet 110, and then moved from the installation section 111 to the shielding section 112, without interfering with the check valve 31. After the first filter 21 is installed, combined with... Figure 5 and Figure 6 Then, the second filter 22 is installed from the installation section 111. The second filter 22 is located directly inside the installation section 111. That is, by simply dividing the filter 20 into two filters, the problem of installation difficulty can be avoided. Secondly, since there are only two filters, the required installation time is relatively short.

[0044] Of course, in other embodiments, three, four or five filters can be set according to actual needs, and multiple filters are arranged sequentially in the air inlet 110 along the first direction OX.

[0045] In one embodiment of this application, combined with Figure 7 At least one inner wall of the air inlet 110 extending along the first direction OX is provided with a groove 113, at least one side wall of the filter screen is located in the groove 113, and the filter screen can slide along the groove 113.

[0046] The inner wall of the air inlet 110 is provided with a sliding groove 113 extending along the first direction OX, and the first filter screen 21 can slide into the shielding section 112 along the sliding groove 113 when being installed in the mounting section 111; the second filter screen 22 is directly installed in the sliding groove 113 of the mounting section 111, and the sliding groove 113 is also used for limiting the side walls of the first filter screen 21 and the second filter screen 22, so as to prevent the filter screens from being taken out of the air inlet 110.

[0047] Further, the mounting section 111 and the shielding section 112 are arranged at intervals; the sliding groove 113 comprises a first sliding groove section 1131, a second sliding groove section 1132 and a third sliding groove section 1133, the first sliding groove section 1131 is located on the inner wall of the shielding section 112, the second sliding groove section 1132 is located on the inner wall of the mounting section 111, and the third sliding groove section 1133 communicates the first sliding groove section 1131 and the second sliding groove section 1132.

[0048] The housing 100 is also provided with two impellers, and a motor is arranged between the two impellers, which is used to drive the two impellers to rotate at the same time. The two impellers correspond to the mounting section 111 and the shielding section 112 respectively, so that each impeller has a separate air inlet 110. Since the motor is located between the two impellers, that is, also located between the mounting section 111 and the shielding section 112, a protective shell 130 is arranged outside the motor, and the protective shell 130 is located between the mounting section 111 and the shielding section 112.

[0049] The first sliding groove section 1131 is located on the inner wall of the shielding section 112, the second sliding groove section 1132 is located on the inner wall of the mounting section 111, and the third sliding groove section 1133 is arranged corresponding to the motor installation position. Although the protective shell 130 does not need to be provided with an air inlet 110 at the position, the third sliding groove section 1133 is also arranged in the protective shell 130, and the first sliding groove section 1131 and the second sliding groove section 1132 are communicated through the third sliding groove section 1133, so that the first filter screen 21 installed from the second sliding groove section 1132 can slide into the first sliding groove section 1131 through the third sliding groove section 1133.

[0050] In an embodiment of the present application, the air inlet 110 has a first inner wall 114 and a second inner wall 115 arranged opposite along the second direction OY, the first inner wall 114 and the second inner wall 115 respectively extend along the first direction OX, the first inner wall 114 is located on the side close to the range hood body 30, and the first inner wall 114 is provided with the sliding groove 113.

[0051] Thus, the first inner wall 114 is located on the side close to the range hood body 30, i.e., the second inner wall 115 is away from the range hood relative to the first inner wall 114. Specifically, the first inner wall 114 and the second inner wall 115 are arranged along the second direction OY, the second direction OY is perpendicular to the first direction OX, the second inner wall 115 is away from the range hood body 30 relative to the first inner wall 114. When installing the first filter screen 21, the filter screen can be first pushed along the second direction OY from the second inner wall 115 to the first inner wall 114 until one end of the filter screen extends into the sliding groove 113 of the installation section 111, and then the filter screen is pushed along the first direction OX, so that the first filter screen 21 slides into the shielding section 112 along the sliding groove 113.

[0052] The second inner wall 115 is away from the range hood relative to the first inner wall 114, i.e., the second inner wall 115 is located on the side close to the external space. When installing the filter screen from the side of the second inner wall 115, the filter screen will not interfere with the range hood, facilitating the installation of the filter screen. The first inner wall 114 is provided with a sliding groove 113, and the second inner wall 115 is not provided with a sliding groove 113. When disassembling the filter screen, the operator moves the filter screen along the second direction OY from the first inner wall 114 to the side of the second inner wall 115, so that the filter screen exits the sliding groove 113, facilitating disassembly.

[0053] Further, the installation section 111 is provided with a limiting edge 116 at both ends along the first direction OX; and / or, the shielding section 112 is provided with a limiting edge 116 at both ends along the first direction OX.

[0054] It can be understood that the installation section 111 is provided with a limiting edge 116 at both ends along the first direction OX; or the shielding section 112 is provided with a limiting edge 116 at both ends along the first direction OX; or the installation section 111 is provided with a limiting edge 116 at both ends along the first direction OX, and the shielding section 112 is provided with a limiting edge 116 at both ends along the first direction OX.

[0055] Specifically, the first filter screen 21 and the second filter screen 22 are rectangular structures, and each of the first filter screen 21 and the second filter screen 22 has two opposite long sides and two opposite short sides connected in sequence, the long sides extend along the first direction OX, and the short sides extend along the second direction OY. When the first filter screen 21 is installed in the shielding section 112, the limiting edges 116 at both ends of the shielding section 112 along the first direction OX can shield the two short sides of the shielding section 112, and one long side of the first filter screen 21 extends into the sliding groove 113 on the first inner wall 114 of the shielding section 112, that is, the first filter screen 21 is limited by three sides respectively, preventing the first filter screen 21 from coming out of the shielding section 112. Similarly, when the second filter screen 22 is installed in the mounting section 111, the limiting edges 116 at both ends of the mounting section 111 along the first direction OX can shield the two short sides of the mounting section 111, and one long side of the second filter screen 22 extends into the sliding groove 113 on the first inner wall 114 of the mounting section 111, that is, the second filter screen 22 is limited by three sides respectively, preventing the second filter screen 22 from coming out of the mounting section 111.

[0056] It should be noted that the protective shell 130 is a limiting edge of the mounting section 111 close to the shielding section 112, and also a limiting edge of the shielding section 112 close to the mounting section 111, that is, when the first filter screen 21 is installed, one end of the first filter screen 21 extends into the protective shell 130; when the second filter screen 22 is installed, one end of the second filter screen 22 extends into the protective shell 130, so as to limit the first filter screen 21 and the second filter screen 22 by the protective shell 130 respectively.

[0057] Further, the filter screen is provided with a handle 23 close to the second inner wall 115.

[0058] Specifically, the present application can be understood as that the first filter screen 21 is provided with a handle 23 close to the second inner wall 115; or the second filter screen 22 is provided with a handle 23 close to the second inner wall 115; or the first filter screen 21 and the second filter screen 22 are respectively provided with handles 23 close to the second inner wall 115.

[0059] For example, the first filter screen 21 is provided with a handle 23 on one side of the second inner wall 115. When installing the first filter screen 21, the first filter screen 21 is extended into the installation section 111 along the second direction OY and the first filter screen 21 is extended into the sliding groove 113, and then the first filter screen 21 is pushed along the first direction OX by the handle 23 to be installed into the shielding section 112. When disassembling the first filter screen 21, the handle 23 on the first filter screen 21 is pulled to move the first filter screen 21 along the first direction OX to the installation section 111, and then the handle 23 is pulled to make the first filter screen 21 exit the installation section 111. For another example, the second filter screen 22 is provided with a handle 23 on one side of the second inner wall 115. When disassembling the second filter screen 22, the handle 23 on the second filter screen 22 is directly pulled to make the second filter screen 22 exit to the installation section 111.

[0060] Specifically, the second inner wall 115 of the installation section 111 is provided with an inclined surface, which facilitates the sliding of the filter screen into the installation section 111 from the inclined surface of the second inner wall 115, and improves the installation efficiency.

[0061] In some embodiments of the present application, a protective shell 130 is arranged between the installation section 111 and the shielding section 112, and part of the first filter screen 21 extends into the protective shell 130.

[0062] In this way, the housing 100 is also provided with two impellers, and a motor is arranged between the two impellers. When the motor rotates, the two impellers are driven to rotate simultaneously. The installation section 111 is the air inlet 110 of one of the impellers, the shielding section 112 is the air inlet 110 of the other impeller, and the protective shell 130 is used to protect the motor.

[0063] When installing the first filter screen 21, the first filter screen 21 needs to enter from the installation section 111, then pass through the protective shell 130 to extend into the shielding section 112. Part of the first filter screen 21 extends into the protective shell 130. On the one hand, the protective shell 130 can be used as a limiting edge 116 of one end of the shielding section 112 along the first direction OX to limit the first filter screen 21 and prevent the first filter screen 21 from exiting the shielding section 112. On the other hand, when the first filter screen 21 moves towards one end of the shielding section 112 along the first direction OX, it is convenient for the operator to insert his fingers into the protective shell 130 to push the first filter screen 21 into place.

[0064] Specifically, the third sliding groove 113 is located in the protective shell 130, and is used for sliding the first filter screen 21 from the second sliding groove section 1132 to the first sliding groove section 1131 through the third sliding groove section 1133.

[0065] Further, the sum of the lengths of the shielding section 112 and the protective shell 130 along the first direction OX is equal to the length of the first filter screen 21 along the first direction OX, and the length of the second filter screen 22 along the first direction OX is equal to the length of the mounting section 111 along the first direction OX.

[0066] When the first filter screen 21 is installed, the operator inserts the first filter screen 21 into one side of the mounting section 111 along the second direction OY, and then pushes the first filter screen 21 along the first direction OX. When the end of the first filter screen 21 close to the mounting section 111 is flush with the protective shell 130, it indicates that the first filter screen 21 is installed in place. That is, by making the sum of the lengths of the shielding section 112 and the protective shell 130 along the first direction OX equal to the length of the first filter screen 21 along the first direction OX, on the one hand, it is convenient for the operator to judge whether the first filter screen 21 is installed in place, and on the other hand, it prevents the operator from having difficulty in pushing the first filter screen 21 with fingers inserted into the protective shell 130. When the first filter screen 21 is installed, the second filter screen 22 can be directly inserted into the mounting section 111 along the second direction OY. The length of the second filter screen 22 along the first direction OX is directly equal to the length of the mounting section 111 along the first direction OX, that is, the second filter screen 22 does not need to be pushed along the first direction OX, and the installation is convenient.

[0067] In some embodiments, the length of the first filter screen 21 along the first direction OX is less than or equal to the length of the mounting section 111 along the first direction OX. For example, the length of the first filter screen 21 along the first direction OX is equal to the length of the mounting section 111 along the first direction OX. When installing, the first filter screen 21 is directly installed into the mounting section 111 along the second direction OY, and then the first filter screen 21 is pushed along the first direction OX to slide into the shielding section 112, thereby making the installation of the first filter screen 21 convenient.

[0068] In other embodiments, the length of the first filter screen 21 along the first direction OX is greater than the length of the mounting section 111 along the first direction OX. When installing the first filter screen 21, the first filter screen 21 needs to be appropriately bent to be installed into the air inlet 110.

[0069] Further, in order to prevent the first filter screen 21 from being bent when being installed, the first filter screen 21 can be split into a first filter section and a second filter section, and the first filter section and the second filter section are connected through buckling. When the first filter screen 21 is installed, first, the first filter section is inserted into the installation section 111 along the second direction OY, and then the first filter section is pushed along the first direction OX until the first filter section partially passes through the protection shell. Then, the second filter section is inserted into the installation section 111 along the second direction OY, and then the first filter section is pushed along the first direction OX until the first filter section and the second filter section are both installed in place. Finally, the second filter screen 22 is directly inserted into the installation section 111 along the second direction OY.

[0070] Further, the first filter section and the second filter section are connected through buckling. After the first filter section is installed, the second filter section is installed, and then the first filter section and the second filter section are connected through buckling. Then, the first filter section and the second filter section are pushed along the first direction OX until they are both installed in place, and then the second filter screen 22 is installed.

[0071] An embodiment of the present application also discloses an extractor hood with a fan function. The extractor hood includes an extractor hood body 30 and a fan module 10. The extractor hood body 30 is provided with a check valve 31. The fan module 10 is installed on the extractor hood body 30. The projection of the fan module 10 along the air inlet direction is at least partially located within the projection range of the shielding section 112 of the check valve 31.

[0072] In this way, when the filter 20 is directly installed to the air inlet 110, the check valve 31 interferes with the filter 20. In this embodiment, the filter 20 includes at least two filter screens, and the air inlet 110 includes an installation section 111 and a shielding section 112. The check valve 31 affects the installation of the filter 20 in the shielding section 112, but has no effect on the installation section 111. Therefore, each filter screen is installed from the installation section 111 to the air inlet 110, and then part of the filter screen is moved from the installation section 111 to the shielding section 112, thereby achieving the installation of the filter 20.

[0073] The at least two filter screens include a first filter screen 21 and a second filter screen 22. The installation method of the filter 20 of the fan module 10 includes the following steps:

[0074] The first filter screen 21 is installed into the installation section 111.

[0075] The first filter screen 21 is pushed along the first direction OX so that the first filter screen 21 covers the shielding section 112.

[0076] The second filter screen 22 is installed into the installation section 111.

[0077] In this way, each filter screen can be loaded from the mounting section 111, avoiding interference between the range hood body and the filter screen when the filter screen is installed, which can cause difficulty in installing the filter screen. When the filter screen is loaded into the air inlet 110, the filter screen is moved in the first direction OX so that each filter screen is positioned in a corresponding position.

[0078] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not conflict, they should be considered within the scope of the present disclosure.

[0079] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
