Description

Technical Field

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

[0002] The range hood has become one of the indispensable kitchen appliances in people's daily life. The range hood can quickly remove the fumes generated by the user during cooking, which can reduce pollution, purify the air, and greatly improve people's quality of life. The range hood is usually equipped with a fan assembly, which usually includes a volute, a motor and an impeller. The impeller can be set in the volute, and the output shaft of the motor can be connected to the impeller. When the motor is working, it can drive the impeller to rotate, so that the range hood can achieve the function of extracting fumes.

[0003] In the existing range hoods, the motor is usually connected to the bottom plate of the volute through a motor bracket. However, since a space needs to be reserved to set the motor bracket, the existing fan assembly usually has a large thickness. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a fan assembly is provided. The fan assembly includes a volute front plate, a volute enclosure plate and a mounting plate, the volute enclosure plate is connected between the volute front plate and the mounting plate, and the volute front plate, the volute enclosure plate and the mounting plate enclose an installation space, the mounting plate is recessed toward the installation space to form an installation portion with an accommodating cavity, the accommodating cavity is located outside the installation space, the installation portion is provided with an installation through hole, and a motor is passed through the installation through hole.

[0005] The fan assembly provided by the utility model has a mounting portion formed on the mounting plate that is recessed toward the inside of the mounting space, and the motor is directly inserted into the mounting through hole on the mounting portion, which is equivalent to directly connecting the motor to the mounting plate without the need to set up a motor bracket in a conventional fan assembly. The thickness of such a fan assembly in the front-to-back direction can naturally be thinner. In addition, since the motor is inserted into the mounting through hole, that is, the motor can pass through the mounting through hole from the outside to the inside, a part of the motor can be located in the mounting space, so that the part of the motor located outside the mounting space can occupy a smaller space, and the setting of the motor occupies less space in the front-to-back direction, so that the thickness of the fan assembly as a whole in the front-to-back direction can be further thinner.

[0006] For example, the motor is divided into a first part and a second part by the mounting through hole, the first part is located in the accommodating cavity, and the second part is located in the mounting space. The motor is arranged without exceeding the part of the outer side of the mounting plate away from the mounting space, so that the arrangement of the motor in the fan assembly occupies less space in the front-to-back direction, so that the thickness of the fan assembly as a whole in the front-to-back direction can be thinner.

[0007] Exemplarily, the mounting portion has a mounting surface facing the inside of the mounting space, and the second part is connected to the mounting surface. On the basis that the motor is inserted into the mounting through hole, the second part is connected to the mounting surface, so that the motor can be more stably connected to the mounting portion, and thus the fan assembly as a whole can be more stable. Moreover, no matter how the second part is connected to the mounting surface, since the mounting surface has a certain area, it will be relatively simple and convenient to connect the second part to the mounting surface, so that the installation process of the fan assembly as a whole can be simpler.

[0008] Exemplarily, the second part is provided with a plurality of connection parts, the plurality of connection parts are arranged around the central axis of the motor, the mounting surface is provided with a plurality of connection matching parts, the plurality of connection matching parts are located around the mounting through hole, and the plurality of connection matching parts are connected to the plurality of connection parts one by one. By connecting the plurality of connection matching parts to the plurality of connection parts one by one, the connection of the second part to the mounting surface can be more stable, and the arrangement of the connection parts and the connection matching parts can make the operation of connecting the second part to the mounting surface simpler.

[0009] Exemplarily, the multiple connecting parts are arranged in a ring shape. The multiple connecting parts are arranged in a ring shape around the central axis CC of the motor, which can ensure that the motor is connected to the mounting part more stably in all directions, so that when the rotating shaft of the motor rotates, it is not easy to drive other parts to vibrate, and the overall structure is more stable.

[0010] Exemplarily, the multiple connecting parts are arranged symmetrically. When the multiple connecting parts are arranged symmetrically, the motor can be more stable when connected to the mounting part, and the overall stability of the fan assembly is also better.

[0011] For example, multiple connecting parts are arranged evenly. In this way, the even arrangement of multiple connecting parts can ensure that the motor is connected to the mounting part with consistent strength in all directions, avoiding the situation where one part is damaged first, so that the overall strength of the fan assembly can be higher and the stability is better. Moreover, multiple connecting parts arranged evenly are easier to produce, and the overall fan assembly is easier to realize.

[0012] For example, the mounting plate is further recessed toward the mounting space to form an assembly groove. All components of the fan assembly that need to be assembled outside the mounting space can be arranged in the assembly groove. The arrangement of the assembly groove can make it unnecessary for the fan assembly to reserve an assembly space on the mounting plate away from the outside of the mounting space, so that the space occupied by the fan assembly as a whole in the front-to-back direction can be smaller and the overall thickness can be thinner.

[0013] Exemplarily, the assembly groove has a first end and a second end that are arranged opposite to each other, the assembly groove is connected to the accommodating cavity at the first end, and a through hole is arranged on the second end, and the through hole passes through the mounting plate. The arrangement of the assembly groove can facilitate the assembly of the components on the outer side of the mounting plate with the components on the inner side of the mounting plate, and such a fan assembly has a simple structure and is easy to implement.

[0014] Exemplarily, the mounting plate has a volute region and a peripheral region surrounding the volute region, the first end is arranged in the volute region, and the second end is arranged on the peripheral region. With such an assembly groove, the internal assembly of the entire fan assembly can be more regular, for example, the internal wiring of the entire fan assembly can be more regular, thereby avoiding safety hazards caused by messy wiring.

[0015] Exemplarily, the motor includes a first part located in the accommodating cavity, and the first part is connected to a wire, and the wire is led out through the assembly groove. The wire connected to the first part is led out through the assembly groove, so there is no need to reserve space on the outside of the mounting plate away from the mounting space to arrange these wires, and the wire connected to the first part is led out through the assembly groove, and the assembly groove can play a role in wire management, thereby preventing the wires connected to the first part from being too messy.

[0016] For example, the assembly slot forms a notch on a side away from the installation space, and a cover plate covering the notch is connected to the mounting plate. The cover plate can limit the wire in the assembly slot, and the cover plate can protect the wire in the assembly slot to prevent the wire from being damaged by external factors, so that the overall stability of the fan assembly can be better.

[0017] Exemplarily, a sealing ring is sleeved on the motor, and the sealing ring is connected to the mounting through hole. By providing the sealing ring, the oil retained in the mounting space can be prevented from flowing to the outside when the fan assembly sucks oil smoke.

[0018] For example, the periphery of the sealing ring is provided with an annular clamping groove, which is clamped to the edge of the mounting through hole. The sealing ring is connected to the mounting through hole by clamping the clamping groove to the edge of the mounting through hole, so that the overall structure is simpler and easier to implement, and the process of setting the clamping groove on the sealing ring is simpler, and the overall structure is easier to produce and process.

[0019] According to another aspect of the utility model, a range hood is provided. The range hood includes a side panel, a top panel and any one of the fan assemblies described above, the side panel and the top panel are respectively connected to the mounting plate, and the side panel, the top panel and the mounting plate are enclosed to form a storage cavity, and the volute front plate and the volute enclosure are located in the storage cavity. The mounting plate, the side panel and the top panel are connected to form a range hood housing, and the volute front plate, the volute enclosure and the mounting plate are connected to form a volute. Here, it can be considered that the mounting plate plays the role of both a conventional volute bottom plate in the volute and a conventional range hood back plate in the range hood. In this way, it is equivalent to directly attaching the volute to the range hood back plate, that is, directly connecting the volute to the mounting plate. Such a range hood omits the volute bottom plate in a conventional range hood, or omits the range hood back plate in a conventional range hood. Such a range hood can naturally be thinner in the front-to-back direction.

[0020] 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.

[0033] 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.

[0034] According to one aspect of the utility model, a fan assembly is provided. The fan assembly can be applied to any suitable device, including but not limited to a range hood. Therefore, according to another aspect of the utility model, a range hood is provided. The fan assembly and the range hood provided by the utility model will be described in detail below in conjunction with the accompanying drawings.

[0035] See also Figure 1 and Figure 2 The range hood 20 may include a range hood top plate 22 and a range hood side plate 21 . The range hood top plate 22 and the range hood side plate 21 may be part of a range hood housing. A storage cavity 23 is formed in the range hood housing. At least a portion of the fan assembly 10 may be disposed in the storage cavity 23 .

[0036] See also Figure 3 , the fan assembly 10 may include a volute front plate 300, a volute enclosure 400 and a mounting plate 100. The volute enclosure 400 may be connected between the volute front plate 300 and the mounting plate 100, and the volute front plate 300, the volute enclosure 400 and the mounting plate 100 may enclose an installation space 500. It can be considered that the installation space 500 is located inside the storage cavity 23. When the volute enclosure 400 is connected between the volute front plate 300 and the mounting plate 100, a portion of the mounting plate 100, the volute front plate 300 and the volute enclosure 400 are equivalent to forming a volute, and a portion of the mounting plate 100 can serve as a volute bottom plate in a conventional volute. An impeller (not shown in the figure) may be provided in the installation space 500.

[0037] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the mounting plate 100 may be recessed toward the mounting space 500 to form a mounting portion 110 having a housing cavity 111. The mounting portion 110 may surround the housing cavity 111, and the opening of the housing cavity 111 may be flush with the outer side of the mounting plate 100 away from the mounting space 500. The housing cavity 111 may be located outside the mounting space 500. Since the mounting space 500 is formed by the mounting plate 100, the volute front plate 300 and the volute enclosure 400, and the mounting portion 110 is a part of the mounting plate 100, for the mounting portion 110 formed by the recess on the mounting plate 100 toward the mounting space 500, it can be considered that the mounting portion 110 causes a portion of the mounting space 500 to be recessed, so that the housing cavity 111 may be considered to be located outside the mounting space 500. The mounting portion 110 may be provided with a mounting through hole 112, and the motor 200 may be passed through the mounting through hole 112. The motor 200 may be inserted into the mounting through hole 112. The mounting through hole 112 may have an opening size matching the motor 200, and the motor 200 may be inserted into the mounting through hole 112 by various means such as snap connection, welding or threaded connection.

[0038] The fan assembly 10 provided by the utility model has a mounting portion 110 formed on the mounting plate 100, which is recessed toward the inside of the mounting space 500, and the motor 200 is directly inserted into the mounting through hole 112 on the mounting portion 110, which is equivalent to directly connecting the motor 200 to the mounting plate 100 without the need to set up a motor bracket in a conventional fan assembly. The thickness of such a fan assembly 10 in the front-to-back direction can naturally be thinner. In addition, since the motor 200 is inserted into the mounting through hole 112, that is, the motor 200 can pass through the mounting through hole from the outside to the inside, a part of the motor 200 can be located in the mounting space 500, so that the part of the motor 200 located outside the mounting space 500 can occupy a smaller space, and the setting of the motor 200 occupies less space in the front-to-back direction, so that the thickness of the fan assembly 10 as a whole in the front-to-back direction can be further thinner.

[0039] In one embodiment of the utility model, the motor 200 can be divided into a first part 210 and a second part 220 through the mounting through hole 112, the first part 210 can be located in the accommodating cavity 111, and the second part 220 can be located in the mounting space 500. It can be considered that the motor 200 passes through the mounting through hole 112 from the outside to the inside, and the first part 210 is located on the outside of the mounting through hole 112, and the second part 220 is located on the inside of the mounting through hole 112. The first part 210 is located in the accommodating cavity 111, and the second part 220 is located in the mounting space 500. The second part 220 can be connected to an impeller. The mounting portion 110 is formed on the mounting plate 100 by being recessed toward the inside of the mounting space 500, and the first portion 210 on the motor 200 is located in the accommodating cavity 111 enclosed by the mounting portion 110. That is to say, the motor 200 is not arranged beyond the portion of the outer side surface of the mounting plate 100 away from the mounting space 500. In this way, the arrangement of the motor 200 in the fan assembly 10 occupies less space in the front-to-back direction, so that the overall thickness of the fan assembly 10 in the front-to-back direction can be thinner.

[0040] In one embodiment of the present invention, see Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the mounting portion 110 may have a mounting surface 114 facing the inside of the mounting space 500, the mounting through hole 112 may be provided on the mounting surface 114, and the second portion 220 may be connected to the mounting surface 114. The mounting surface 114 may have a certain area. For example, the mounting surface 114 may be annular with the mounting through hole 112 provided in the middle area. The second portion 220 may be connected to the mounting surface 114 in various forms such as snap-on, welding or threaded connection. On the basis that the motor 200 is provided in the mounting through hole 112, the second portion 220 is connected to the mounting surface 114, so that the motor 200 can be more stably connected to the mounting portion 110, and thus the fan assembly 10 as a whole can be more stable. Moreover, no matter in what form the second portion 220 is connected to the mounting surface 114, since the mounting surface 114 has a certain area, it will be relatively simple and convenient to connect the second portion 220 to the mounting surface 114, so that the installation process of the fan assembly 10 as a whole can be simpler.

[0041] For example, see Figure 8 , the mounting surface 114 can be parallel to the mounting plate 100. The positioning wall 113 is parallel to the mounting plate 100. In this way, the central axis (axis CC in the figure) of the motor 200 passing through the mounting through hole 112 can be perpendicular to the mounting plate 100, so that the shaking caused by the rotating shaft of the motor 200 when rotating is smaller, and the internal structure of the fan assembly 10 can be more regular, and the overall structure can be more stable.

[0042] In one embodiment of the present invention, see Figure 8 , the second part 220 may be provided with a plurality of connection parts 221, and the plurality of connection parts 221 may be provided around the central axis CC of the motor 200. The mounting surface 114 may be provided with a plurality of connection matching parts 1141, and the plurality of connection matching parts 1141 may be located around the mounting through hole 112, and the plurality of connection matching parts 1141 may be connected to the plurality of connection parts 221 in a one-to-one correspondence. By using fasteners to penetrate the connection parts 221 and the connection matching parts 1141, the second part 220 may be threadedly connected to the mounting surface 114. By connecting the plurality of connection matching parts 1141 in a one-to-one correspondence with the plurality of connection parts 221, the connection of the second part 220 to the mounting surface 114 may be more stable, and the setting of the connection parts 221 and the connection matching parts 1141 may make the operation of connecting the second part 220 to the mounting surface 114 simpler.

[0043] Exemplarily, the plurality of connecting parts 221 may be arranged in a ring shape. The plurality of connecting parts 221 may be arranged in a ring shape around the central axis CC of the motor 200, which can ensure that the motor 200 is more stably connected to the mounting part 110 in all directions, so that the rotation shaft of the motor 200 is not likely to cause other components to vibrate when rotating, and the overall structure is more stable.

[0044] For example, the multiple connecting parts 221 can be arranged symmetrically. The symmetrical arrangement of the multiple connecting parts 221 can be that the multiple connecting parts 221 are arranged centrally and symmetrically around the central axis CC of the motor 200, or the multiple connecting parts 221 are arranged axially and symmetrically, or the multiple connecting parts 221 can be arranged symmetrically in any other form. When the multiple connecting parts 221 are arranged symmetrically, the motor 200 can be more stable when connected to the mounting part 110, and the overall stability of the fan assembly 10 is also better.

[0045] For example, the plurality of connection parts 221 may be arranged evenly. The spacing between two adjacent connection parts 221 in the plurality of connection parts 221 may be equal. In this way, the even arrangement of the plurality of connection parts 221 can ensure that the motor 200 is connected to the mounting part 110 with consistent strength in all directions, avoiding the situation where one part is damaged first, so that the overall strength of the fan assembly 10 can be higher and the stability is better. Moreover, the evenly arranged plurality of connection parts 221 are easier to produce, and the fan assembly 10 as a whole is also easier to implement.

[0046] In one embodiment of the present invention, see Figure 7, the mounting plate 100 may also be recessed toward the mounting space 500 to form an assembly groove 120. The recessed direction of the assembly groove 120 may be the same as that of the mounting portion 110. The first portion 210 on the motor 200 may be connected to a wire, which may be arranged in the assembly groove 120. Other components on the fan assembly 10 that need to be arranged outside the mounting space 500 may also be arranged in the assembly groove 120. All components on the fan assembly 10 that need to be assembled outside the mounting space 500 may be arranged in the assembly groove 120. The provision of the assembly groove 120 may eliminate the need for the fan assembly 10 to reserve an assembly space on the mounting plate 100 away from the outside of the mounting space 500, so that the space occupied by the fan assembly 10 as a whole in the front-to-back direction may be smaller, and the overall thickness may be thinner.

[0047] For example, see Figure 7 and Figure 8 , the assembly groove 120 may have a first end 121 and a second end 122 that are arranged opposite to each other, the assembly groove 120 may be connected to the accommodating cavity 111 at the first end 121, and a through hole 1221 may be provided on the second end 122, and the through hole 1221 may penetrate the mounting plate 100. Some components arranged on the outside of the mounting plate 100 may be assembled with components located in the storage cavity 23 through the assembly groove 120. For example, the wire connected to the first part 210 needs to be connected to the power supply in the storage cavity 23, so the wire may enter the storage cavity 23 through the through hole 1221 on the assembly groove 120. The provision of the assembly groove 120 may facilitate the assembly of components on the outside of the mounting plate 100 with components on the inside of the mounting plate 100, and such a fan assembly 10 has a simple structure and is easy to implement.

[0048] For example, see Figure 7 and Figure 8, the mounting plate 100 may have a volute region 130 and a peripheral region 140 surrounding the volute region 130, the first end 121 may be disposed in the volute region 130, and the second end 122 may be disposed on the peripheral region 140. The edge of the volute region 130 may have a trend substantially the same as the contour line of the volute enclosure 400. The volute enclosure 400 may be connected to the edge of the volute region 130. When the components on the outside of the mounting plate 100 need to be assembled with the components on the inside of the mounting plate 100, they usually need to be assembled with the components located in the storage cavity 23 but outside the installation space 500. Take the example that the wire connected to the motor 200 needs to be connected to the power supply inside the storage cavity 23 for explanation. The power supply inside the storage cavity 23 is usually located outside the installation space 500, so after the wire connected to the first part 210 enters the assembly groove 120 from the accommodating cavity 111 through the first end 121, it can enter the storage cavity through the through hole 1221 on the second end 122, so as to be connected to the power supply. With such an assembly groove 120, the internal assembly of the fan assembly 10 as a whole can be more regular, for example, the internal wiring of the fan assembly 10 as a whole can be more regular, thereby avoiding safety hazards caused by messy wiring.

[0049] Exemplarily, the motor 200 may include a first portion 210 located in the accommodating cavity 111, and a wire may be connected to the first portion 210, and the wire may be led out through the assembly groove 120. The wire connected to the first portion 210 is led out through the assembly groove 120, so that there is no need to reserve space on the mounting plate 100 away from the outside of the mounting space 500 to arrange these wires, and the wire connected to the first portion 210 is led out through the assembly groove 120, and the assembly groove 120 can play a role in wire management, thereby preventing the wires connected to the first portion 210 from being too messy.

[0050] For example, the assembly slot 120 may form a notch on a side away from the installation space 500, and a cover plate covering the notch may be connected to the mounting plate 100. The cover plate may limit the wire in the assembly slot 120, and the cover plate may protect the wire in the assembly slot 120, preventing the wire from being damaged by external factors, so that the overall stability of the fan assembly 10 may be better.

[0051] For example, see Figure 4 and Figure 8, a sealing ring 230 may be sleeved on the motor 200, and the sealing ring 230 may be connected to the mounting through hole 112. The sealing ring 230 may be annular, and the motor 200 may pass through the sealing ring 230 so as to realize that the sealing ring 230 is sleeved on the motor 200. The sealing ring 230 may be connected to the mounting through hole 112 in various forms such as snap connection, welding or threaded connection. By providing the sealing ring 230, the oil retained in the installation space 500 may be prevented from flowing to the outside when the fan assembly 10 is sucking oil smoke.

[0052] For example, see Figure 8 The periphery of the sealing ring 230 may be provided with an annular clamping groove 231, and the clamping groove 231 may be clamped to the edge of the mounting through hole 112. The sealing ring 230 is connected to the mounting through hole 112 by clamping the clamping groove 231 to the edge of the mounting through hole 112, so that the overall structure is simpler and easier to implement, and the process of setting the clamping groove 231 on the sealing ring 230 is simpler, and the overall structure is easier to produce and process.

[0053] For the range hood 20 provided by the present invention, see Figure 1 and Figure 2 The range hood 20 may include a range hood side panel 21, a range hood top panel 22, and any of the fan assemblies 10 described above. The range hood side panel 21 and the range hood top panel 22 may be connected to the mounting plate 100, respectively. The mounting plate 100, the range hood side panel 21, and the range hood top panel 22 may form a part of the range hood housing. In this case, the mounting plate 100 may function as a range hood back panel in a conventional range hood. The range hood side panel 21, the range hood top panel 22, and the mounting plate 100 may enclose a storage cavity 23, and the volute front panel 300 and the volute enclosure 400 may be located in the storage cavity 23. The mounting plate 100, the range hood side plate 21 and the range hood top plate 22 are connected to form a range hood casing, and the volute front plate 300, the volute enclosure 400 and the mounting plate 100 are connected to form a volute. It can be considered here that the mounting plate 100 plays the role of both a conventional volute bottom plate in the volute and a conventional range hood back plate in the range hood 20. In this way, it is equivalent to directly connecting the volute to the range hood back plate, that is, directly connecting to the mounting plate 100. Such a range hood 20 omits the volute bottom plate in a conventional range hood, or omits the range hood back plate in a conventional range hood. Naturally, the thickness of such a range hood 20 in the front-to-back direction can be thinner.

[0054] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front", "back", "up", "down", "left", "right", "lateral", "vertical", "vertical", "horizontal", "top", "bottom", etc. are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description.
