[0053] The present disclosure provides a table-top range hood. As illustrated in FIG. 1 to FIG. 5, in some embodiments, the table-top range hood includes a main body 1000 and a support 2000. The main body 1000 is rotatably connected to the support 2000 and swingable with respect to the support, and the main body 1000 has at least two swing positions with respect to the support 2000.

[0054] The main body 1000 can swing with respect to the support 2000. By controlling the main body 1000 to swing with respect to the support 2000, an extraction direction can be adjusted, improving convenience of use. In addition, the at least two swing positions are formed at the main body 1000 with respect to the support 2000. When the main body 1000 swings to be in a corresponding swing position, stability of the main body 1000 can be enhanced, and thus the main body 1000 is less likely to rotate randomly with respect to the support 2000.

[0055] In an exemplary embodiment of the present disclosure, the table-top range hood includes the main body 1000 and the support 2000. The main body 1000 is mounted at the support 2000. The support 2000 of the table-top range hood is placed on a table, so that the main body 1000 is maintained at a predetermined distance from the table-top. The main body 1000 is configured to extract fume.

[0056] The main body 1000 includes a duct housing 1100, a support 1200, a fan 1300, and a filter 1400. The duct housing 1100 is provided with an air duct 1110. The duct housing 1100 may be integrally formed or may be formed by connecting at least two parts. The air duct 1110 has an end constructed as an air inlet 1111 and another end constructed as an air outlet 1112. The support 1200 is disposed in the air duct 1110 and fixed through connecting to the duct housing 1100. There are many connection methods between the support 1200 and the duct housing 1100, such as welding, screwing, and engagement. It should be understood that the support 1200 is a component for supporting other parts. The support 1200 may be processed by metallic materials or other materials. The support 1200 may have a regular shape or an irregular shape. In this embodiment, the support 1200 is a sheet metal part, and the so-called sheet metal part is processed by a sheet metal process. The fan 1300 is connected to the support 1200 so as to be fixed in the air duct 1110. In this case, the fan 1300 is located between the air inlet 1111 and the air outlet 1112. The fan 1300 drives the fume to enter the air duct 1110 from the air inlet 1111 and to be discharged from the air duct 1110 through the air outlet 1112. The filter 1400 is mounted to the duct housing 1100 and is located in the air duct 1110. The filter 1400 is located upstream the fan 1300, for example, at the air inlet 1111. The fume flows through the filter 1400 and then flows through the fan 1300. By disposing the filter 1400, the fume can be filtered to obtain oil. The support 2000 realizes support for the main body 1000. The table-top range hood includes an oil cup 2400 mounted to the support 2000. Oil discharged from the main body 1000 finally enters the oil cup 2400 for temporary storage.

[0057] In the related art, the main body 1000 is mounted to the support 2000 and is immovable with respect to the support 2000. Therefore, when the table-top range hood is placed on the table, the main body 1000 can only extract the fume in a specific direction. When the extraction direction needs to be adjusted, it is often necessary to adjust a position of a whole table-top range hood, which brings inconvenience in operation.

[0058] For this reason, in this embodiment, the main body 1000 can be rotatably connected to the support 2000, in such a manner that the main body 1000 can swing with respect to the support 2000. When the table-top range hood is placed on the table, a user can control the main body 1000 to swing with respect to the support 2000 (i.e., the main body 1000 rotates with respect to the support 2000) to adjust an orientation of the main body 1000. For example, the main body 1000 swings with respect to the support 2000 to a position where a maximum amount of fume is collected. Compared with adjusting the whole machine, it is more convenient to swing the main body 1000.

[0059] The main body 1000 swings with respect to the support 2000 in a variety of ways. For example, taking the user facing the air inlet 1111 as a reference, a side of the table-top range hood facing the user is the front, a side facing away from the user is the rear, a side corresponding to the left hand of the user is the left, a side corresponding to the right hand of the user is the right, a side close to the table-top is the lower, and a side facing away from the table-top is the upper. The main body 1000 can be swingable in an up-down direction with respect to the support 2000 (enabling the main body 1000 to extract fume from different heights), or can be swingable in a left-right direction with respect to the support 2000 (enabling the main body 1000 to extract fume within different ranges horizontally).

[0060] It should be understood that since swinging of the main body 1000 is realized through rotation, to prevent the main body 1000 from rotating freely / accidentally with respect to the support 2000 (that is, when the main body 1000 swings to the corresponding position, to prevent the main body 1000 freely / accidentally from leaving the position), the at least two swing positions are formed at the main body 1000 with respect to the support 2000. The main body 1000 can rotate to the corresponding swing position. That is, the main body 1000 can rotate at least two angles with respect to the support 2000, and each swing position corresponds to an angle. When the main body 1000 swings to a predetermined swing position, a predetermined restraint action is formed between the main body 1000 and the support 2000, which can effectively prevent the main body 1000 from deviating from the current swing position with respect to the support 2000 on the premise of a non-artificial force, preventing the main body 1000 from rotating freely / accidentally. Through the above arrangement, stability of the main body 1000 with respect to the support 2000 can be enhanced.

[0061] As illustrated in FIG. 5, FIG. 7, FIG. 9, FIG. 10, FIG. 11, FIG. 12, and FIG. 13, in some embodiments, one of the main body 1000 and the support 2000 is provided with a first connection member 1600, and another of the main body 1000 and the support 2000 is provided with a second connection member 2500. The second connection member 2500 includes a shaft hole 2510. The first connection member 1600 includes a rotation shaft 1610. The rotation shaft 1610 is rotatably connected to the shaft hole 2510 to enable the main body 1000 to be rotatably connected to the support 2000.

[0062] In an exemplary embodiment of the present disclosure, one of the main body 1000 and the support 2000 is provided with the first connection member 1600, and the other of the main body 1000 and the support 2000 is provided with the second connection member 2500. Here, it should be understood as that when one of the main body 1000 and the support 2000 is provided with the first connection member 1600, the other is provided with the second connection member 2500 correspondingly. For example, when the main body 1000 is provided with the first connection member 1600, the support 2000 is provided with the second connection member 2500 correspondingly. When the main body 1000 is provided with the second connection member 2500, the support 2000 is provided with the first connection member 1600 correspondingly. Cooperation between the shaft hole 2510 and the rotation shaft 1610 can realize rotatable connection between the first connection member 1600 and the second connection member 2500, which can realize rotatable connection between the main body 1000 and the support 2000.

[0063] Further, as illustrated in FIG. 9 and FIG. 10, in some embodiments, the second connection member 2510 has two shaft holes 2510 (means that there are at least two shaft holes 2510). The first connection member 1600 include two rotation shafts 1610 (means that there are at least two rotation shafts 1610) corresponding to the two shaft holes 2510 in a one-to-one correspondence. The two shaft holes 2510 are arranged opposite to each other and spaced apart from each other. The first connection member 1600 is formed between the two shaft holes 2510. Through the above arrangement, stability of the rotatable connection between the main body 1000 and the support 2000 can be enhanced.

[0064] In an exemplary embodiment of the present disclosure, with reference to an orientation illustrated in FIG. 9 and FIG. 10, the two shaft holes 2510 are arranged opposite to each other and spaced apart from each other in the left-right direction. The first connection member 1600 is located between a left-side shaft hole 2510 and a right-side shaft hole 2510. One of the two rotation shafts 1610 protrudes from a left side of the first connection member 1600 and is inserted into the left-side shaft hole 2510, and another of the two rotation shafts 1610 protrudes from a right side of the first connection member 1600 and is inserted into the right-side shaft hole 2510. The left-side rotation shaft 1610 is rotatably connected to the left-side shaft hole 2510. The right-side rotation shaft 1610 is rotatably connected to the right-side shaft hole 2510. In this way, the rotatable connection between the first connection member 1600 and the second connection member 2500 can be enhanced, and stability of the rotatable connection between the first connection member 1600 and the second connection member 2500 also can be enhanced, enhancing the stability of the rotatable connection between the main body 1000 and the support 2000.

[0065] When the two shaft holes 2510 and the two rotation shafts 1610 are arranged, in order to facilitate assembly of the first connection member 1600 and the second connection member 2500, as illustrated in FIG. 9, in some embodiments, the first connection member 1600 includes a rotation shaft housing 1620 and a first elastic member 1630 (for example, springs). The rotation shaft 1610 is slidably disposed at the rotation shaft housing 1620, and the first elastic member 1630 is disposed between the rotation shaft 1610 and the rotation shaft housing 1620. The first elastic member 1630 is configured to exert a force on the rotation shaft 1610 towards the shaft hole 2510.

[0066] In an exemplary embodiment of the present disclosure, the rotation shaft housing 1620 includes two cavities 1621 (that is, spaces for sliding the rotation shafts 1610) and two first elastic members 1630. The two cavities 1621 are arranged in the left-right direction and separated from each other. One of the two first elastic members 1630 is disposed at a left-side cavity 1621, and one of the two rotation shafts 1610 is slidably arranged in the left-side cavity 1621. Another of the two first elastic members 1630 is disposed at a right-side cavity 1621, and another of the two rotation shafts 1610 is slidably arranged in the right-side cavity 1621. The left-side first elastic member 1630 has an end inserted into the left-side rotation shaft 1610, and another end abutting with a cavity bottom of the left-side cavity 1621. The right-side first elastic member 1630 has an end inserted into the right-side rotation shaft 1610, and another end abutting with a cavity bottom of the right-side cavity 1621. The left-side first elastic member 1630 exerts a force on the left-side rotation shaft 1610 towards the left-side shaft hole 2510, allowing the left-side rotation shaft 1610 to penetrate the rotation shaft housing 1620 to be exposed. The right-side first elastic member 1630 exerts a force on the right-side rotation shaft 1610 towards the right-side shaft hole 2510, allowing the right-side rotation shaft 1610 to penetrate the rotation shaft housing 1620 to be exposed. When the first connection member 1600 is fitted to the second connection member 2500, the rotation shaft 1610 is controlled to retract (retract towards the cavity 1621). The rotation shaft 1610 slides with respect to the cavity 1621 when the rotation shaft 1610 retracts to drive the first elastic member 1630 to deform. The first elastic member 1630 accumulates elastic potential energy. When the first connection member 1600 and the second connection member 2500 are assembled in place, the first elastic member 1630 releases the elastic potential energy, pushing the rotation shaft 1610 to slide with respect to the cavity 1621 (opposite to the aforementioned sliding direction). The rotation shaft 1610 is exposed through penetrating the rotation shaft housing 1620, and inserted into the shaft hole 2510 to realize rotatable connection between the rotation shaft 1610 and the shaft hole 2510.

[0067] Further, as illustrated in FIG. 11 to FIG. 13, in some embodiments, the rotation shaft 1610 has an inclined guide surface 1611 configured to abut with a periphery of the shaft hole 2510 when the first connection member 1600 is fitted to the second connection member 2500, in such a manner that the rotation shaft 1610 retracts and then extends to be inserted into the shaft hole 2510.

[0068] In an exemplary embodiment of the present disclosure, when the first connection member 1600 is fitted to the second connection member 2500, the first connection member 1600 can be controlled to move towards the second connection member 2500, enable the guide inclined guide surface 1611 abutting with the periphery of the shaft hole 2510. As the first connection member 1600 continues to move towards the second connection member 2500, the periphery of the shaft hole 2510 generates a force on the inclined guide surface 1611 and generates a component force in an axial direction of the rotation shaft 1610, in such a manner that the rotation shaft 1610 retracts (retracts towards the cavity 1621). The first elastic member 1630 accumulates the elastic potential energy until the first connection member 1600 is moved into place. In this case, the first elastic member 1630 releases the elastic potential energy to drive the rotation shaft 1610 to be inserted into the shaft hole 2510. During this process, the user is kept from directly contacting the rotation shaft 1610, more conveniently realizing assembly between the first connection member 1600 and the second connection member 2500.

[0069] As illustrated in FIG. 5, FIG. 8, and FIG. 10 to FIG. 12, in some embodiments, one of the main body 1000 and the support 2000 is provided with a first limit member 1700, and another of the main body 1000 and the support 2000 is provided with a second limit member 2600. The second limit member 2600 has at least two limit grooves 2610. The first limit member 1700 can snap into any one of the at least two limit grooves 2610 when the main body 1000 swings, forming the at least two swing positions of the main body 1000 with respect to the support 2000.

[0070] In an exemplary embodiment of the present disclosure, one of the main body 1000 and the support 2000 is provided with the first limit member 1700, and the other of the main body 1000 and the support 2000 is provided with the second limit member 2600. Here, it should be understood as that when one of the main body 1000 and the support 2000 is provided with the first limit member 1700, the other is provided with the second limit member 2600 correspondingly. For example, when the main body 1000 is provided with the first limit member 1700, the support 2000 is provided with the second limit member 2600 correspondingly. When the main body 1000 is provided with the second limit member 2600, the support 2000 is provided with the first limit member 1700 correspondingly. The first limit member 1700 is inserted into one of the at least two limit grooves 2610 to form a swing position. Since the second limit member 2600 has the at least two limit grooves 2610, the at least two swing positions are provided. For example, the structure shown in FIG. 1 has two limit grooves 2610. Therefore, two swing positions are provided. The main body 1000 can be adjusted up and down.

[0071] As illustrated in FIG. 8, in some embodiments, the first limit member 1700 includes: a housing 1710; a catch pin 1720 slidably disposed in the housing 1710; and a second elastic member 1730 (such as a spring) disposed between the catch pin 1720 and the housing 1710. The second elastic member 1730 is configured to exert a force on the catch pin 1720. The catch pin 1720 can be disengaged from a current limit groove 2610 when the main body 1000 swings and snaps into a corresponding limit groove 2610 under an action of the second elastic member 1730 when the main body 1000 swings into one of the at least two swing positions. Through the above cooperation, switching between different swing positions can be facilitated.

[0072] For example, with reference to the structure illustrated in FIG. 5 and FIG. 8, the catch pin 1720 snaps into a lower limit groove 2610 in this case. When the user controls the main body 1000 to swing downwards, the catch pin 1720 is disengaged from the lower limit groove 2610 (e.g., the current limit groove 2610) under an action of a force. The catch pin 1720 is retracted towards the housing 1710. The second elastic member 1730 is deformed to accumulate the elastic potential energy. As the main body 1000 swings into one of the at least two swing positions, the second elastic member 1730 releases the elastic potential energy, driving the catch pin 1720 to extend to snap into an upper limit groove 2610 (e.g., the corresponding limit groove 2610).

[0073] Further, as illustrated in FIG. 8, in some embodiments, the catch pin 1720 has an arc-shaped end face. The limit groove 2610 has an arc-shaped groove wall. When the catch pin 1720 snap into the limit groove 2610, the arc-shaped end face abuts with the arc-shaped groove wall. When the user controls the main body 1000 to swing, a force between the arc-shaped end face and the arc-shaped groove wall enables the catch pin 1720 more easily to retract.

[0074] As illustrated in FIG. 5, FIG. 8, FIG. 11, and FIG. 12, in some embodiments, the main body 1000 is swingable in an up-down direction with respect to the support 2000. The table-top range hood further includes a panel 1800 disposed at the main body 1000 and is designed to be inserted into the support 2000. Through arrangement of the panel 1800, regardless of which swing position the main body 1000 is in, the panel 1800 can block a space between the main body 1000 and the support 2000, preventing the user from observing an internal structure of the table-top range hood by the space between the main body 1000 and the support 2000.

[0075] On the premise of disposing the panel 1800, one of the first limit member 1700 and the second limit member 2600 may be disposed at the panel 1800, or one of the first connection member 1600 and the second connection member 2500 may also be disposed at the panel 1800. For example, in FIG. 11, the first connection member 1600 and the first limit member 1700 are both disposed at the panel 1800. In addition, the first connection member 1600 is located at a front side of the panel 1800, and the first limit member 1700 is located at a rear side of the panel 1800.

[0076] As illustrated in FIG. 1 to FIG. 4, in some embodiments, the table-top range hood further includes a base 3000. The support 2000 is fixed to the base 3000. That is, when the table-top range hood is placed on the table, the base 3000 is in contact with the table. The base 3000 realizes support for the support 2000 and the main body 1000. In addition, in this embodiment, in an up-down direction, a projection of the base 3000 is designed as larger than a projection of the support 2000, improving placement stability of the table-top range hood. Through the above arrangement, the base 3000 can be made thin enough to realize the support for the support 2000 and the main body 1000. In addition, since the base 3000 is closer to the table, occupancy on the user's usable space can be reduced as much as possible.

[0077] In particular, the projection of the support 2000 is designed to be located within the projection of the base 3000, and the projection of the support 2000 is spaced apart from the projection of the base 3000, in such a manner that supporting stability of the support 2000 and the main body 1000 in the direction (a circumferential direction) surrounding the base 3000 is further improved.

[0078] As illustrated in FIG. 5, FIG. 7, and FIG. 14, the main body 1000 has an oil relief port 1150 and is adapted to discharge oil through the oil relief port 1150. The table-top range hood further includes a first deflector 2100, a second deflector 2200 and an oil cup 2400. The first deflector 2100 is fixed to the main body 1000, and is configured to receive the oil discharged from the oil relief port 1150. The first deflector 2100 has a first outlet 2120, and is configured to discharge the oil through the first outlet 2120. The second deflector 2200 has a second inlet 2210 and a second outlet 2220. The first outlet 2120 is designed to be inserted into the second inlet 2210, and the first deflector 2100 is spaced apart from the second deflector 2200. The second deflector 2200 is configured to receive the oil discharged from the first outlet 2120 and to discharge the oil through the second outlet 2220. The oil cup 2400 is configured to receive the oil discharged from the second outlet 2220, and is designed to be detachable.

[0079] The first deflector 2100 is configured to receive the oil discharged from the oil relief port 1150. That is, the oil discharged from the oil relief port 1150 enters the first deflector 2100. The oil is guided under an action of the first deflector 2100, and then is discharged from a first outlet 2120 of the first deflector 2100. The first deflector 2100 receives the oil discharged from the oil relief port 1150, either directly (the oil discharged from the oil relief port 1150 directly enters the first deflector 2100) or indirectly (the oil discharged from the oil relief port 1150 indirectly enters the first deflector 2100). For example, the first deflector 2100 is disposed below the oil relief port 1150. The oil discharged from the oil relief port 1150 enters the first deflector 2100 under an action of gravity. The first deflector 2100 guides the oil entering the first deflector 2100. The oil continues to flow under the action of gravity, and then is discharged from the first deflector 2100 through the first outlet 2120.

[0080] The second deflector 2200 is configured to receive the oil discharged from the first outlet 2120. That is, the oil discharged from the first outlet 2120 enters the second deflector 2200. The oil is guided under an action of the second deflector, and then is discharged from a second outlet 2220 of the second deflector 2200. For example, the second deflector 2200 is disposed below the first outlet 2120. The oil discharged from the first outlet 2120 enters the second deflector 2200 under the action of gravity. The second deflector 2200 guides the oil entering the second deflector 2200. The oil continues to flow under the action of gravity, and then is discharged from the second deflector 2200 through the second outlet 2220.

[0081] Since the first deflector 2100 is fixed to the main body 1000, a position of the first deflector 2100 may change with swinging of the main body 1000. To ensure communication between the first deflector 2100 and the second deflector 2200, in this embodiment, the first outlet 2120 is designed to be inserted into the second inlet 2210, and the first deflector 2100 is designed to be spaced apart from the second deflector 2200. That is, the second inlet 2210 is much larger than the first outlet 2120. An end where the first outlet 2120 of the first deflector 2100 is located is inserted into an end where the second inlet 2210 of the second deflector 2200 is located, in such a manner that the first outlet 2120 is located within a range of an outline of the second inlet 2210. When the main body 1000 swings with respect to the support 2000, the first deflector 2100 follows to move and can ensure communication with the second deflector 2200.

[0082] The oil cup 2400 is configured to receive the oil discharged from the second outlet 2220. That is, the oil discharged from the second outlet 2220 enters the oil cup 2400 for temporary storage. The oil discharged from the second outlet 2220 may directly enter the oil cup 2400 or indirectly enter the oil cup 2400. The oil cup 2400 is designed to be detachable. That is, the oil cup 2400 can be mounted to a predetermined position or detachable, so that the user can remove the oil cup 2400 to pour the oil and clean the oil cup 2400, and can remount the cleaned oil cup 2400 to the predetermined position.

[0083] As illustrated in FIG. 1, FIG. 2, FIG. 5, and FIG. 6, in some embodiments, the main body 1000 includes: a duct housing 1100, a light-transmitting cover 1510, and a light-emitter 1520. The duct housing 1100 has an air inlet 1111 facing a first orientation. The light-transmitting cover 1510 is connected to the duct housing 1100 and defines an accommodation cavity 1530 together with the duct housing 1100. The light-emitter 1520 disposed in the accommodation cavity 1530, and is adapted to emit light. The light is adapted to pass through the light-transmitting cover 1510 and irradiate towards the first orientation.

[0084] By disposing the light-emitter 1520, the air inlet 1111 faces the first orientation and the light emitted by the light-emitter 1520 irradiates towards the first orientation. In this way, the user can easily observe an extraction effect, providing reference for adjusting a position of the table-top range hood for the user or providing reference for a swing position of the main body 1000. Further, by disposing the light-emitter 1520, the table-top range hood is suitable for use in the outdoor without lights or under low-light conditions. In addition, the light-emitter 1520 is disposed in the accommodation cavity 1530 defined by the light-transmitting cover 1510 and the duct housing 1100 to prevent the light-emitter 1520 from being contaminated by the fume. Compared with cleaning the light-emitter 1520, it is easier to clean the light-transmitting cover 1510.

[0085] In an exemplary embodiment of the present disclosure, the air inlet 1111 faces the first orientation. For example, taking the user facing the air inlet 1111 as a reference, the side of the table-top range hood facing the user is the front, the side facing away from the user is the rear, the side corresponding to the left hand of the user is the left, the side corresponding to the right hand of the user is the right, the side close to the table-top is the lower, and the side facing away from the table-top is the upper. The first orientation points to a front space of the table-top range hood. That is, the table-top range hood extracts the fume from the front space by the air inlet 1111.

[0086] The light can pass through the light-transmitting cover 1510. That is, the light-transmitting cover 1510 has a transparent or translucent structure. The light-transmitting cover 1510 is connected to the duct housing 1100, enabling the accommodation cavity 1530 to be formed between the light-transmitting cover 1510 and the duct housing 1100. The light-emitter 1520 is disposed in the accommodation cavity 1530. The light-emitter 1520 is a component that can emit the light. For example, with a common light-emitter 1520 as a lamp bead, the light-emitter 1520 can emit the light when the lamp bead is energized. The light emitted by the light-emitter 1520 can pass through the light-transmitting cover 1510 and irradiate towards the first orientation (i.e., irradiate towards the front space of the table-top range hood). It should be understood that since the air inlet 1111 faces the first orientation, when the table-top range hood is in operation, the fume is extracted and flows from a space indicated by the first direction (the front space of the table-top range hood) to the air inlet 1111. In this case, the light emitted by the light-emitter 1520 passes through the light-transmitting cover 1510 and irradiates towards the space indicated by the first direction (the front space of the table-top range hood). The light can be reflected and refracted when passing through the light-transmitting cover 1510. Due to presence of a large number of oil mist particles in the fume, the light encounters these particles and undergoes reflection and refraction, in such a manner that the user can observe a flow direction of the fume and the extraction effect of the fume is visually presented to the user. Through the above arrangement, since the user can directly observe the extraction effect of the fume, adjusting the table-top range hood to the suitable position or adjusting the main body 1000 to a suitable swing position can be facilitated for the user. Precisely, by disposing the light-emitter 1520, which is suitable for use in the outdoor without lights or a dim environment, a lighting effect can also be provided.

[0087] It should be noted that the table-top range hood can produce oil adhesion during extracting the fume. In this embodiment, the light-emitter 1520 is disposed in the accommodation cavity 1530 defined by the light-transmitting cover 1510 and the duct housing 1100. It is difficult for the fume to enter the accommodation cavity 1530 to prevent the light-emitter 1520 from being contaminated by the fume. Even if the fume contaminates the light-transmitting cover 1510, it is much more convenient for the user to clean the light-transmitting cover 1510 than to clean the light-emitter 1520.

[0088] As illustrated in FIG. 1, FIG. 2, FIG. 6, and FIG. 7, in some embodiments, the air inlet 1111 is surrounded by the accommodation cavity 1600. In this way, the light can be emitted towards the first orientation in a direction surrounding the air inlet 1111, improving coverage of the light. Therefore, flow of the fume can be easily observed when the fume is extracted. Since the accommodation cavity 1600 is defined by the light-transmitting cover 1510 and the duct housing 1100, the light-transmitting cover 1510 also needs to surround the air inlet 1111. For example, in the structure illustrated in FIG. 2, the light-transmitting cover 1510 is of a circular ring shape and mounted at an air inlet end of the duct housing 1100. When the light-emitter 1520 emits the light, the table-top range hood can form a light-emitting ring to improve an irradiation range of the fume, further facilitating observation of the flow of the fume for the user.

[0089] Further, on the premise that the light-transmitting cover 1510 is also designed to surround the air inlet 1111, as illustrated in FIG. 1, FIG. 2, and FIG. 16, in some embodiments, the light-transmitting cover 1510 is tapered in a flow direction of fume, which can provide flow guidance for the fume entering the air inlet 1111, reducing turbulence at the air inlet 1111, and thus is conducive to improving the extraction effect of the fume and reducing noise.

[0090] As illustrated in FIG. 1 and FIG. 2, in some embodiments, the light-emitter 1520 is of a strip shape and is arranged in an extension direction of the accommodation cavity 1530.

[0091] In an exemplary embodiment of the present disclosure, the strip-shaped light-emitter 1520 constitutes a lamp strip, which may include a plurality of lamp beads. The light-emitter 1520 is arranged in the extension direction of the accommodation cavity 1530, that is, surrounding the air outlet 1112. Therefore, a corresponding light source exists in the direction surrounding the air outlet 1112, to emit the light passing through the light-transmitting cover 1510, further improving intensity of light emission, which is more conducive to improving an illumination effect.

[0092] As illustrated in FIG. 6 and FIG. 15, in some embodiments, the duct housing 1100 has a recess 1140. The light-transmitting cover 1510 covers the recess 1140 and defines the accommodation cavity 1530 together with the recess 1140. The light-emitter 1520 is connected to a recess wall of the recess 1140.

[0093] In an exemplary embodiment of the present disclosure, with reference to an orientation illustrated in FIG. 15, the recess 1140 of the duct housing 1100 is opened towards the front. During assembly, the light-emitter 1520 can be connected to the recess wall of the recess 1140 to realize fixation of the light-emitter 1520. Then, the light-transmitting cover 1510 can be connected to the duct housing 1100 and cover the recess 1140 to define the accommodation cavity 1530 between the light-transmitting cover 1510 and the duct housing 1100 (the recess 1140 is at least part of the accommodation cavity 1530) to form protection for the light-emitter 1520. It can be understood that the light-transmitting cover 1510 is a separate component to be mounted last. The light-emitter 1520 is first connected to the recess wall of the recess 1140 to be fixed, so as to facilitate wiring and power supply.

[0094] Further, as illustrated in FIG. 15, in some embodiments, the recess wall of the recess 1140 includes a recess bottom wall 1141 and recess side walls 1142 at two opposite sides of the recess bottom wall 1141, respectively. Therefore, an opening is formed between the recess side walls 1142 at the two opposite sides of the recess bottom wall 1141. As illustrated in FIG. 15, the recess 1140 has an opening and faces the front. The light-emitter 1520 is mounted at the recess side wall 1142 at one side of the two opposite sides of the recess bottom wall 1141. For example, the light-emitter 1520 is mounted at the recess side wall 1142 at a lower side of the orientation illustrated in FIG. 15, and emits the light towards the recess side wall 1142 at another side of the two opposite sides of the recess bottom wall 1141 (a recess side wall 1142 at an upper side). The light emitted by the light-emitter 1520 is reflected by the recess side wall 1142 at the other side of the two opposite sides of the recess bottom wall 1141 (the recess side wall 1142 at the upper side) and passes through the light-transmitting cover 1510 to irradiate towards the first orientation. The light emitted by the light-emitter 1520 is further diverged after being reflected, improving light emitting uniformity of the light-transmitting cover 1510.

[0095] As illustrated in FIG. 1 to FIG. 7, in some embodiments, the duct housing 1100 includes a first housing 1120 and a mounting frame 1130. The mounting frame 1130 is connected to an inner wall of the first housing 1120 and surrounds the air inlet 1111. The light-transmitting cover 1510 connects to the mounting frame 1130 and defines the accommodation cavity 1530 together with the mounting frame 1130.

[0096] In an exemplary embodiment of the present disclosure, the first housing 1120 constitutes a majority of the duct housing 1100. The mounting frame 1130 is connected to an inner wall of an air inlet end of the first housing 1120. The light-transmitting cover 1510 is connected to the mounting frame 1130. The mounting frame 1130 and the first housing 1120, as independent components, are connected and fixed to each other by means of a connection method. By designing the mounting frame 1130 as an independent component, mounting of connection structures at the mounting frame 1130 can be facilitated, especially in a case where various types of connection structures are disposed at the mounting frame 1130. Compared to integral forming of the mounting frame 1130 and the first housing 1120, this embodiment can effectively reduce manufacturing complexity. Further, when it is necessary to mounted other parts to an inside of the first housing 1120, the mounting frame 1130 may be connected to the first housing 1120 after mounting of these parts, so as to avoid interference.

[0097] There are various ways to connect the mounting frame 1130 to the first housing 1120. For example, the mounting frame 1130 is snap-connected to the first housing 1120, which is quick and easy without direct manipulation by the user as long as the mounting frame 1130 is controlled to align with a corresponding position of the first housing 1120 to move into place until the snap-connection occurs. In addition, since the mounting frame 1130 is connected to the inner wall of the first housing 1120, the connection structures between the mounting frame 1130 and the first housing 1120 can be concealed once the snap-connection is performed, which can avoid exposure of a connection mechanism. Similarly, the light-transmitting cover 1510 may also be designed to be snap-connected to the mounting frame 1130.

[0098] As illustrated in FIG. 1 to FIG. 7, in some embodiments, the filter 1400 is connected to the mounting frame 1130. That is, both the light-transmitting cover 1510 and the filter 1400 need to be connected and fixed to the mounting frame 1130. Since the mounting frame 1130 is the independent component with respect to the first housing 1120, the mounting frame 1130 is easily designed with a connection structure configured to connect to the light-transmitting cover 1510 and a connection structure configured to connect to the filter 1400.

[0099] As illustrated in FIG. 5, FIG. 7, and FIG. 17, in some embodiments, the filter 1400 has an oil discharge opening 1428. The mounting frame 1130 has an oil relief port 1150. The oil discharge opening 1428 is inserted into the oil relief port 1150 to enable the oil discharge opening 1428 to be in communication with the oil relief port 1150. The filter 1400 discharges the filtered oil by the oil discharge opening 1428. Then, the oil is discharged from the main body 1000 by the oil relief port 1150. Through enabling the oil discharge opening 1428 to be inserted into the oil relief port 1150, positioning of the filter 1400 and discharging of the oil can be realized.

[0100] As illustrated in FIG. 18 to FIG. 20, in some embodiments, the filter 1400 includes a filter screen 1410 and a filter screen frame 1420. The filter screen frame 1420 has an oil collecting groove 1427. The oil discharge opening 1428 is disposed at the filter screen frame 1420. In addition, the oil discharge opening 1428 is in communication with the oil collecting groove 1427. The filter screen 1410 is disposed in the filter screen frame 1420 and located in the oil collecting groove 1427.

[0101] In an exemplary embodiment of the present disclosure, the filter screen frame 1420 is a skeleton structure of the filter 1400 and is configured to support the filter screen 1410. The filter screen 1410 is disposed at the filter screen frame 1420 to be supported. The filter screen 1410 has a porous structure, which can not only allow the fume to flow, but also filter the fume to obtain the oil. In this embodiment, the filter screen frame 1420 has the oil collecting groove 1427. In addition, the filter screen 1410 is located at the oil collecting groove 1427, and the filter screen 1410 is surrounded by the oil collecting groove 1427. When the filter screen 1410 filters the fume to obtain the oil, the oil flows along the filter screen 1410 until the oil enters the oil collecting groove 1427. By disposing of the oil collecting groove 1427, the oil separated from the filter screen 1410 is collected and then is discharged from the oil discharge opening 1428.

[0102] As illustrated in FIG. 18 to FIG. 20, in some embodiments, the filter screen frame 1420 includes a first frame 1421 and a second frame 1422. The first frame 1421 and the second frame 1422 are connected to each other to clamp the filter screen 1410, thereby supporting the filter screen 1410. In addition, after the first frame 1421 and the second frame 1422 are connected and fixed to each other, the oil collecting groove 1427 and the oil discharge opening 1428 are defined between the first frame 1421 and the second frame 1422. In this way, assembly between the filter screen frame 1420 and the filter screen 1410 can be facilitated on the basis of forming the oil collecting groove 1427 and the oil discharge opening 1428. For example, an assembly process between the filter screen frame 1420 and the filter screen 1410 is as follows: the filter screen 1410 is placed at the first frame 1421, and then the second frame 1422 is controlled to be connected to the first frame 1421. After the second frame 1422 and the first frame 1421 are connected and fixed to each other, the filter screen 1410 can be fixed and the oil collecting groove 1427 and the oil discharge opening 1428 can be defined, in this case the filter screen 1410 is located in the oil collecting groove 1427.

[0103] Although some embodiments of the present disclosure are described above, the scope of the present disclosure is not limited to the embodiments. Under the concept of the present disclosure, any equivalent structure transformation made using the contents of the specification and the accompanying drawings of the present disclosure, or any direct or indirect application of the contents of the specification and the accompanying drawings of the present disclosure in other related fields, shall equally fall within the scope of the present disclosure.

[0053] The present disclosure provides a table-top range hood. As illustrated in FIG. 1 to FIG. 5, in some embodiments, the table-top range hood includes a main body 1000 and a support 2000. The main body 1000 is rotatably connected to the support 2000 and swingable with respect to the support, and the main body 1000 has at least two swing positions with respect to the support 2000.

[0054] The main body 1000 can swing with respect to the support 2000. By controlling the main body 1000 to swing with respect to the support 2000, an extraction direction can be adjusted, improving convenience of use. In addition, the at least two swing positions are formed at the main body 1000 with respect to the support 2000. When the main body 1000 swings to be in a corresponding swing position, stability of the main body 1000 can be enhanced, and thus the main body 1000 is less likely to rotate randomly with respect to the support 2000.

[0055] In an exemplary embodiment of the present disclosure, the table-top range hood includes the main body 1000 and the support 2000. The main body 1000 is mounted at the support 2000. The support 2000 of the table-top range hood is placed on a table, so that the main body 1000 is maintained at a predetermined distance from the table-top. The main body 1000 is configured to extract fume.

[0056] The main body 1000 includes a duct housing 1100, a support 1200, a fan 1300, and a filter 1400. The duct housing 1100 is provided with an air duct 1110. The duct housing 1100 may be integrally formed or may be formed by connecting at least two parts. The air duct 1110 has an end constructed as an air inlet 1111 and another end constructed as an air outlet 1112. The support 1200 is disposed in the air duct 1110 and fixed through connecting to the duct housing 1100. There are many connection methods between the support 1200 and the duct housing 1100, such as welding, screwing, and engagement. It should be understood that the support 1200 is a component for supporting other parts. The support 1200 may be processed by metallic materials or other materials. The support 1200 may have a regular shape or an irregular shape. In this embodiment, the support 1200 is a sheet metal part, and the so-called sheet metal part is processed by a sheet metal process. The fan 1300 is connected to the support 1200 so as to be fixed in the air duct 1110. In this case, the fan 1300 is located between the air inlet 1111 and the air outlet 1112. The fan 1300 drives the fume to enter the air duct 1110 from the air inlet 1111 and to be discharged from the air duct 1110 through the air outlet 1112. The filter 1400 is mounted to the duct housing 1100 and is located in the air duct 1110. The filter 1400 is located upstream the fan 1300, for example, at the air inlet 1111. The fume flows through the filter 1400 and then flows through the fan 1300. By disposing the filter 1400, the fume can be filtered to obtain oil. The support 2000 realizes support for the main body 1000. The table-top range hood includes an oil cup 2400 mounted to the support 2000. Oil discharged from the main body 1000 finally enters the oil cup 2400 for temporary storage.

[0057] In the related art, the main body 1000 is mounted to the support 2000 and is immovable with respect to the support 2000. Therefore, when the table-top range hood is placed on the table, the main body 1000 can only extract the fume in a specific direction. When the extraction direction needs to be adjusted, it is often necessary to adjust a position of a whole table-top range hood, which brings inconvenience in operation.

[0058] For this reason, in this embodiment, the main body 1000 can be rotatably connected to the support 2000, in such a manner that the main body 1000 can swing with respect to the support 2000. When the table-top range hood is placed on the table, a user can control the main body 1000 to swing with respect to the support 2000 (i.e., the main body 1000 rotates with respect to the support 2000) to adjust an orientation of the main body 1000. For example, the main body 1000 swings with respect to the support 2000 to a position where a maximum amount of fume is collected. Compared with adjusting the whole machine, it is more convenient to swing the main body 1000.

[0059] The main body 1000 swings with respect to the support 2000 in a variety of ways. For example, taking the user facing the air inlet 1111 as a reference, a side of the table-top range hood facing the user is the front, a side facing away from the user is the rear, a side corresponding to the left hand of the user is the left, a side corresponding to the right hand of the user is the right, a side close to the table-top is the lower, and a side facing away from the table-top is the upper. The main body 1000 can be swingable in an up-down direction with respect to the support 2000 (enabling the main body 1000 to extract fume from different heights), or can be swingable in a left-right direction with respect to the support 2000 (enabling the main body 1000 to extract fume within different ranges horizontally).

[0060] It should be understood that since swinging of the main body 1000 is realized through rotation, to prevent the main body 1000 from rotating freely / accidentally with respect to the support 2000 (that is, when the main body 1000 swings to the corresponding position, to prevent the main body 1000 freely / accidentally from leaving the position), the at least two swing positions are formed at the main body 1000 with respect to the support 2000. The main body 1000 can rotate to the corresponding swing position. That is, the main body 1000 can rotate at least two angles with respect to the support 2000, and each swing position corresponds to an angle. When the main body 1000 swings to a predetermined swing position, a predetermined restraint action is formed between the main body 1000 and the support 2000, which can effectively prevent the main body 1000 from deviating from the current swing position with respect to the support 2000 on the premise of a non-artificial force, preventing the main body 1000 from rotating freely / accidentally. Through the above arrangement, stability of the main body 1000 with respect to the support 2000 can be enhanced.

[0061] As illustrated in FIG. 5, FIG. 7, FIG. 9, FIG. 10, FIG. 11, FIG. 12, and FIG. 13, in some embodiments, one of the main body 1000 and the support 2000 is provided with a first connection member 1600, and another of the main body 1000 and the support 2000 is provided with a second connection member 2500. The second connection member 2500 includes a shaft hole 2510. The first connection member 1600 includes a rotation shaft 1610. The rotation shaft 1610 is rotatably connected to the shaft hole 2510 to enable the main body 1000 to be rotatably connected to the support 2000.

[0062] In an exemplary embodiment of the present disclosure, one of the main body 1000 and the support 2000 is provided with the first connection member 1600, and the other of the main body 1000 and the support 2000 is provided with the second connection member 2500. Here, it should be understood as that when one of the main body 1000 and the support 2000 is provided with the first connection member 1600, the other is provided with the second connection member 2500 correspondingly. For example, when the main body 1000 is provided with the first connection member 1600, the support 2000 is provided with the second connection member 2500 correspondingly. When the main body 1000 is provided with the second connection member 2500, the support 2000 is provided with the first connection member 1600 correspondingly. Cooperation between the shaft hole 2510 and the rotation shaft 1610 can realize rotatable connection between the first connection member 1600 and the second connection member 2500, which can realize rotatable connection between the main body 1000 and the support 2000.

[0063] Further, as illustrated in FIG. 9 and FIG. 10, in some embodiments, the second connection member 2510 has two shaft holes 2510 (means that there are at least two shaft holes 2510). The first connection member 1600 include two rotation shafts 1610 (means that there are at least two rotation shafts 1610) corresponding to the two shaft holes 2510 in a one-to-one correspondence. The two shaft holes 2510 are arranged opposite to each other and spaced apart from each other. The first connection member 1600 is formed between the two shaft holes 2510. Through the above arrangement, stability of the rotatable connection between the main body 1000 and the support 2000 can be enhanced.

[0064] In an exemplary embodiment of the present disclosure, with reference to an orientation illustrated in FIG. 9 and FIG. 10, the two shaft holes 2510 are arranged opposite to each other and spaced apart from each other in the left-right direction. The first connection member 1600 is located between a left-side shaft hole 2510 and a right-side shaft hole 2510. One of the two rotation shafts 1610 protrudes from a left side of the first connection member 1600 and is inserted into the left-side shaft hole 2510, and another of the two rotation shafts 1610 protrudes from a right side of the first connection member 1600 and is inserted into the right-side shaft hole 2510. The left-side rotation shaft 1610 is rotatably connected to the left-side shaft hole 2510. The right-side rotation shaft 1610 is rotatably connected to the right-side shaft hole 2510. In this way, the rotatable connection between the first connection member 1600 and the second connection member 2500 can be enhanced, and stability of the rotatable connection between the first connection member 1600 and the second connection member 2500 also can be enhanced, enhancing the stability of the rotatable connection between the main body 1000 and the support 2000.

[0065] When the two shaft holes 2510 and the two rotation shafts 1610 are arranged, in order to facilitate assembly of the first connection member 1600 and the second connection member 2500, as illustrated in FIG. 9, in some embodiments, the first connection member 1600 includes a rotation shaft housing 1620 and a first elastic member 1630 (for example, springs). The rotation shaft 1610 is slidably disposed at the rotation shaft housing 1620, and the first elastic member 1630 is disposed between the rotation shaft 1610 and the rotation shaft housing 1620. The first elastic member 1630 is configured to exert a force on the rotation shaft 1610 towards the shaft hole 2510.

[0066] In an exemplary embodiment of the present disclosure, the rotation shaft housing 1620 includes two cavities 1621 (that is, spaces for sliding the rotation shafts 1610) and two first elastic members 1630. The two cavities 1621 are arranged in the left-right direction and separated from each other. One of the two first elastic members 1630 is disposed at a left-side cavity 1621, and one of the two rotation shafts 1610 is slidably arranged in the left-side cavity 1621. Another of the two first elastic members 1630 is disposed at a right-side cavity 1621, and another of the two rotation shafts 1610 is slidably arranged in the right-side cavity 1621. The left-side first elastic member 1630 has an end inserted into the left-side rotation shaft 1610, and another end abutting with a cavity bottom of the left-side cavity 1621. The right-side first elastic member 1630 has an end inserted into the right-side rotation shaft 1610, and another end abutting with a cavity bottom of the right-side cavity 1621. The left-side first elastic member 1630 exerts a force on the left-side rotation shaft 1610 towards the left-side shaft hole 2510, allowing the left-side rotation shaft 1610 to penetrate the rotation shaft housing 1620 to be exposed. The right-side first elastic member 1630 exerts a force on the right-side rotation shaft 1610 towards the right-side shaft hole 2510, allowing the right-side rotation shaft 1610 to penetrate the rotation shaft housing 1620 to be exposed. When the first connection member 1600 is fitted to the second connection member 2500, the rotation shaft 1610 is controlled to retract (retract towards the cavity 1621). The rotation shaft 1610 slides with respect to the cavity 1621 when the rotation shaft 1610 retracts to drive the first elastic member 1630 to deform. The first elastic member 1630 accumulates elastic potential energy. When the first connection member 1600 and the second connection member 2500 are assembled in place, the first elastic member 1630 releases the elastic potential energy, pushing the rotation shaft 1610 to slide with respect to the cavity 1621 (opposite to the aforementioned sliding direction). The rotation shaft 1610 is exposed through penetrating the rotation shaft housing 1620, and inserted into the shaft hole 2510 to realize rotatable connection between the rotation shaft 1610 and the shaft hole 2510.

[0067] Further, as illustrated in FIG. 11 to FIG. 13, in some embodiments, the rotation shaft 1610 has an inclined guide surface 1611 configured to abut with a periphery of the shaft hole 2510 when the first connection member 1600 is fitted to the second connection member 2500, in such a manner that the rotation shaft 1610 retracts and then extends to be inserted into the shaft hole 2510.

[0068] In an exemplary embodiment of the present disclosure, when the first connection member 1600 is fitted to the second connection member 2500, the first connection member 1600 can be controlled to move towards the second connection member 2500, enable the guide inclined guide surface 1611 abutting with the periphery of the shaft hole 2510. As the first connection member 1600 continues to move towards the second connection member 2500, the periphery of the shaft hole 2510 generates a force on the inclined guide surface 1611 and generates a component force in an axial direction of the rotation shaft 1610, in such a manner that the rotation shaft 1610 retracts (retracts towards the cavity 1621). The first elastic member 1630 accumulates the elastic potential energy until the first connection member 1600 is moved into place. In this case, the first elastic member 1630 releases the elastic potential energy to drive the rotation shaft 1610 to be inserted into the shaft hole 2510. During this process, the user is kept from directly contacting the rotation shaft 1610, more conveniently realizing assembly between the first connection member 1600 and the second connection member 2500.

[0069] As illustrated in FIG. 5, FIG. 8, and FIG. 10 to FIG. 12, in some embodiments, one of the main body 1000 and the support 2000 is provided with a first limit member 1700, and another of the main body 1000 and the support 2000 is provided with a second limit member 2600. The second limit member 2600 has at least two limit grooves 2610. The first limit member 1700 can snap into any one of the at least two limit grooves 2610 when the main body 1000 swings, forming the at least two swing positions of the main body 1000 with respect to the support 2000.

[0070] In an exemplary embodiment of the present disclosure, one of the main body 1000 and the support 2000 is provided with the first limit member 1700, and the other of the main body 1000 and the support 2000 is provided with the second limit member 2600. Here, it should be understood as that when one of the main body 1000 and the support 2000 is provided with the first limit member 1700, the other is provided with the second limit member 2600 correspondingly. For example, when the main body 1000 is provided with the first limit member 1700, the support 2000 is provided with the second limit member 2600 correspondingly. When the main body 1000 is provided with the second limit member 2600, the support 2000 is provided with the first limit member 1700 correspondingly. The first limit member 1700 is inserted into one of the at least two limit grooves 2610 to form a swing position. Since the second limit member 2600 has the at least two limit grooves 2610, the at least two swing positions are provided. For example, the structure shown in FIG. 1 has two limit grooves 2610. Therefore, two swing positions are provided. The main body 1000 can be adjusted up and down.

[0071] As illustrated in FIG. 8, in some embodiments, the first limit member 1700 includes: a housing 1710; a catch pin 1720 slidably disposed in the housing 1710; and a second elastic member 1730 (such as a spring) disposed between the catch pin 1720 and the housing 1710. The second elastic member 1730 is configured to exert a force on the catch pin 1720. The catch pin 1720 can be disengaged from a current limit groove 2610 when the main body 1000 swings and snaps into a corresponding limit groove 2610 under an action of the second elastic member 1730 when the main body 1000 swings into one of the at least two swing positions. Through the above cooperation, switching between different swing positions can be facilitated.

[0072] For example, with reference to the structure illustrated in FIG. 5 and FIG. 8, the catch pin 1720 snaps into a lower limit groove 2610 in this case. When the user controls the main body 1000 to swing downwards, the catch pin 1720 is disengaged from the lower limit groove 2610 (e.g., the current limit groove 2610) under an action of a force. The catch pin 1720 is retracted towards the housing 1710. The second elastic member 1730 is deformed to accumulate the elastic potential energy. As the main body 1000 swings into one of the at least two swing positions, the second elastic member 1730 releases the elastic potential energy, driving the catch pin 1720 to extend to snap into an upper limit groove 2610 (e.g., the corresponding limit groove 2610).

[0073] Further, as illustrated in FIG. 8, in some embodiments, the catch pin 1720 has an arc-shaped end face. The limit groove 2610 has an arc-shaped groove wall. When the catch pin 1720 snap into the limit groove 2610, the arc-shaped end face abuts with the arc-shaped groove wall. When the user controls the main body 1000 to swing, a force between the arc-shaped end face and the arc-shaped groove wall enables the catch pin 1720 more easily to retract.

[0074] As illustrated in FIG. 5, FIG. 8, FIG. 11, and FIG. 12, in some embodiments, the main body 1000 is swingable in an up-down direction with respect to the support 2000. The table-top range hood further includes a panel 1800 disposed at the main body 1000 and is designed to be inserted into the support 2000. Through arrangement of the panel 1800, regardless of which swing position the main body 1000 is in, the panel 1800 can block a space between the main body 1000 and the support 2000, preventing the user from observing an internal structure of the table-top range hood by the space between the main body 1000 and the support 2000.

[0075] On the premise of disposing the panel 1800, one of the first limit member 1700 and the second limit member 2600 may be disposed at the panel 1800, or one of the first connection member 1600 and the second connection member 2500 may also be disposed at the panel 1800. For example, in FIG. 11, the first connection member 1600 and the first limit member 1700 are both disposed at the panel 1800. In addition, the first connection member 1600 is located at a front side of the panel 1800, and the first limit member 1700 is located at a rear side of the panel 1800.

[0076] As illustrated in FIG. 1 to FIG. 4, in some embodiments, the table-top range hood further includes a base 3000. The support 2000 is fixed to the base 3000. That is, when the table-top range hood is placed on the table, the base 3000 is in contact with the table. The base 3000 realizes support for the support 2000 and the main body 1000. In addition, in this embodiment, in an up-down direction, a projection of the base 3000 is designed as larger than a projection of the support 2000, improving placement stability of the table-top range hood. Through the above arrangement, the base 3000 can be made thin enough to realize the support for the support 2000 and the main body 1000. In addition, since the base 3000 is closer to the table, occupancy on the user's usable space can be reduced as much as possible.

[0077] In particular, the projection of the support 2000 is designed to be located within the projection of the base 3000, and the projection of the support 2000 is spaced apart from the projection of the base 3000, in such a manner that supporting stability of the support 2000 and the main body 1000 in the direction (a circumferential direction) surrounding the base 3000 is further improved.

[0078] As illustrated in FIG. 5, FIG. 7, and FIG. 14, the main body 1000 has an oil relief port 1150 and is adapted to discharge oil through the oil relief port 1150. The table-top range hood further includes a first deflector 2100, a second deflector 2200 and an oil cup 2400. The first deflector 2100 is fixed to the main body 1000, and is configured to receive the oil discharged from the oil relief port 1150. The first deflector 2100 has a first outlet 2120, and is configured to discharge the oil through the first outlet 2120. The second deflector 2200 has a second inlet 2210 and a second outlet 2220. The first outlet 2120 is designed to be inserted into the second inlet 2210, and the first deflector 2100 is spaced apart from the second deflector 2200. The second deflector 2200 is configured to receive the oil discharged from the first outlet 2120 and to discharge the oil through the second outlet 2220. The oil cup 2400 is configured to receive the oil discharged from the second outlet 2220, and is designed to be detachable.

[0079] The first deflector 2100 is configured to receive the oil discharged from the oil relief port 1150. That is, the oil discharged from the oil relief port 1150 enters the first deflector 2100. The oil is guided under an action of the first deflector 2100, and then is discharged from a first outlet 2120 of the first deflector 2100. The first deflector 2100 receives the oil discharged from the oil relief port 1150, either directly (the oil discharged from the oil relief port 1150 directly enters the first deflector 2100) or indirectly (the oil discharged from the oil relief port 1150 indirectly enters the first deflector 2100). For example, the first deflector 2100 is disposed below the oil relief port 1150. The oil discharged from the oil relief port 1150 enters the first deflector 2100 under an action of gravity. The first deflector 2100 guides the oil entering the first deflector 2100. The oil continues to flow under the action of gravity, and then is discharged from the first deflector 2100 through the first outlet 2120.

[0080] The second deflector 2200 is configured to receive the oil discharged from the first outlet 2120. That is, the oil discharged from the first outlet 2120 enters the second deflector 2200. The oil is guided under an action of the second deflector, and then is discharged from a second outlet 2220 of the second deflector 2200. For example, the second deflector 2200 is disposed below the first outlet 2120. The oil discharged from the first outlet 2120 enters the second deflector 2200 under the action of gravity. The second deflector 2200 guides the oil entering the second deflector 2200. The oil continues to flow under the action of gravity, and then is discharged from the second deflector 2200 through the second outlet 2220.

[0081] Since the first deflector 2100 is fixed to the main body 1000, a position of the first deflector 2100 may change with swinging of the main body 1000. To ensure communication between the first deflector 2100 and the second deflector 2200, in this embodiment, the first outlet 2120 is designed to be inserted into the second inlet 2210, and the first deflector 2100 is designed to be spaced apart from the second deflector 2200. That is, the second inlet 2210 is much larger than the first outlet 2120. An end where the first outlet 2120 of the first deflector 2100 is located is inserted into an end where the second inlet 2210 of the second deflector 2200 is located, in such a manner that the first outlet 2120 is located within a range of an outline of the second inlet 2210. When the main body 1000 swings with respect to the support 2000, the first deflector 2100 follows to move and can ensure communication with the second deflector 2200.

[0082] The oil cup 2400 is configured to receive the oil discharged from the second outlet 2220. That is, the oil discharged from the second outlet 2220 enters the oil cup 2400 for temporary storage. The oil discharged from the second outlet 2220 may directly enter the oil cup 2400 or indirectly enter the oil cup 2400. The oil cup 2400 is designed to be detachable. That is, the oil cup 2400 can be mounted to a predetermined position or detachable, so that the user can remove the oil cup 2400 to pour the oil and clean the oil cup 2400, and can remount the cleaned oil cup 2400 to the predetermined position.

[0083] As illustrated in FIG. 1, FIG. 2, FIG. 5, and FIG. 6, in some embodiments, the main body 1000 includes: a duct housing 1100, a light-transmitting cover 1510, and a light-emitter 1520. The duct housing 1100 has an air inlet 1111 facing a first orientation. The light-transmitting cover 1510 is connected to the duct housing 1100 and defines an accommodation cavity 1530 together with the duct housing 1100. The light-emitter 1520 disposed in the accommodation cavity 1530, and is adapted to emit light. The light is adapted to pass through the light-transmitting cover 1510 and irradiate towards the first orientation.

[0084] By disposing the light-emitter 1520, the air inlet 1111 faces the first orientation and the light emitted by the light-emitter 1520 irradiates towards the first orientation. In this way, the user can easily observe an extraction effect, providing reference for adjusting a position of the table-top range hood for the user or providing reference for a swing position of the main body 1000. Further, by disposing the light-emitter 1520, the table-top range hood is suitable for use in the outdoor without lights or under low-light conditions. In addition, the light-emitter 1520 is disposed in the accommodation cavity 1530 defined by the light-transmitting cover 1510 and the duct housing 1100 to prevent the light-emitter 1520 from being contaminated by the fume. Compared with cleaning the light-emitter 1520, it is easier to clean the light-transmitting cover 1510.

[0085] In an exemplary embodiment of the present disclosure, the air inlet 1111 faces the first orientation. For example, taking the user facing the air inlet 1111 as a reference, the side of the table-top range hood facing the user is the front, the side facing away from the user is the rear, the side corresponding to the left hand of the user is the left, the side corresponding to the right hand of the user is the right, the side close to the table-top is the lower, and the side facing away from the table-top is the upper. The first orientation points to a front space of the table-top range hood. That is, the table-top range hood extracts the fume from the front space by the air inlet 1111.

[0086] The light can pass through the light-transmitting cover 1510. That is, the light-transmitting cover 1510 has a transparent or translucent structure. The light-transmitting cover 1510 is connected to the duct housing 1100, enabling the accommodation cavity 1530 to be formed between the light-transmitting cover 1510 and the duct housing 1100. The light-emitter 1520 is disposed in the accommodation cavity 1530. The light-emitter 1520 is a component that can emit the light. For example, with a common light-emitter 1520 as a lamp bead, the light-emitter 1520 can emit the light when the lamp bead is energized. The light emitted by the light-emitter 1520 can pass through the light-transmitting cover 1510 and irradiate towards the first orientation (i.e., irradiate towards the front space of the table-top range hood). It should be understood that since the air inlet 1111 faces the first orientation, when the table-top range hood is in operation, the fume is extracted and flows from a space indicated by the first direction (the front space of the table-top range hood) to the air inlet 1111. In this case, the light emitted by the light-emitter 1520 passes through the light-transmitting cover 1510 and irradiates towards the space indicated by the first direction (the front space of the table-top range hood). The light can be reflected and refracted when passing through the light-transmitting cover 1510. Due to presence of a large number of oil mist particles in the fume, the light encounters these particles and undergoes reflection and refraction, in such a manner that the user can observe a flow direction of the fume and the extraction effect of the fume is visually presented to the user. Through the above arrangement, since the user can directly observe the extraction effect of the fume, adjusting the table-top range hood to the suitable position or adjusting the main body 1000 to a suitable swing position can be facilitated for the user. Precisely, by disposing the light-emitter 1520, which is suitable for use in the outdoor without lights or a dim environment, a lighting effect can also be provided.

[0087] It should be noted that the table-top range hood can produce oil adhesion during extracting the fume. In this embodiment, the light-emitter 1520 is disposed in the accommodation cavity 1530 defined by the light-transmitting cover 1510 and the duct housing 1100. It is difficult for the fume to enter the accommodation cavity 1530 to prevent the light-emitter 1520 from being contaminated by the fume. Even if the fume contaminates the light-transmitting cover 1510, it is much more convenient for the user to clean the light-transmitting cover 1510 than to clean the light-emitter 1520.

[0088] As illustrated in FIG. 1, FIG. 2, FIG. 6, and FIG. 7, in some embodiments, the air inlet 1111 is surrounded by the accommodation cavity 1600. In this way, the light can be emitted towards the first orientation in a direction surrounding the air inlet 1111, improving coverage of the light. Therefore, flow of the fume can be easily observed when the fume is extracted. Since the accommodation cavity 1600 is defined by the light-transmitting cover 1510 and the duct housing 1100, the light-transmitting cover 1510 also needs to surround the air inlet 1111. For example, in the structure illustrated in FIG. 2, the light-transmitting cover 1510 is of a circular ring shape and mounted at an air inlet end of the duct housing 1100. When the light-emitter 1520 emits the light, the table-top range hood can form a light-emitting ring to improve an irradiation range of the fume, further facilitating observation of the flow of the fume for the user.

[0089] Further, on the premise that the light-transmitting cover 1510 is also designed to surround the air inlet 1111, as illustrated in FIG. 1, FIG. 2, and FIG. 16, in some embodiments, the light-transmitting cover 1510 is tapered in a flow direction of fume, which can provide flow guidance for the fume entering the air inlet 1111, reducing turbulence at the air inlet 1111, and thus is conducive to improving the extraction effect of the fume and reducing noise.

[0090] As illustrated in FIG. 1 and FIG. 2, in some embodiments, the light-emitter 1520 is of a strip shape and is arranged in an extension direction of the accommodation cavity 1530.

[0091] In an exemplary embodiment of the present disclosure, the strip-shaped light-emitter 1520 constitutes a lamp strip, which may include a plurality of lamp beads. The light-emitter 1520 is arranged in the extension direction of the accommodation cavity 1530, that is, surrounding the air outlet 1112. Therefore, a corresponding light source exists in the direction surrounding the air outlet 1112, to emit the light passing through the light-transmitting cover 1510, further improving intensity of light emission, which is more conducive to improving an illumination effect.

[0092] As illustrated in FIG. 6 and FIG. 15, in some embodiments, the duct housing 1100 has a recess 1140. The light-transmitting cover 1510 covers the recess 1140 and defines the accommodation cavity 1530 together with the recess 1140. The light-emitter 1520 is connected to a recess wall of the recess 1140.

[0093] In an exemplary embodiment of the present disclosure, with reference to an orientation illustrated in FIG. 15, the recess 1140 of the duct housing 1100 is opened towards the front. During assembly, the light-emitter 1520 can be connected to the recess wall of the recess 1140 to realize fixation of the light-emitter 1520. Then, the light-transmitting cover 1510 can be connected to the duct housing 1100 and cover the recess 1140 to define the accommodation cavity 1530 between the light-transmitting cover 1510 and the duct housing 1100 (the recess 1140 is at least part of the accommodation cavity 1530) to form protection for the light-emitter 1520. It can be understood that the light-transmitting cover 1510 is a separate component to be mounted last. The light-emitter 1520 is first connected to the recess wall of the recess 1140 to be fixed, so as to facilitate wiring and power supply.

[0094] Further, as illustrated in FIG. 15, in some embodiments, the recess wall of the recess 1140 includes a recess bottom wall 1141 and recess side walls 1142 at two opposite sides of the recess bottom wall 1141, respectively. Therefore, an opening is formed between the recess side walls 1142 at the two opposite sides of the recess bottom wall 1141. As illustrated in FIG. 15, the recess 1140 has an opening and faces the front. The light-emitter 1520 is mounted at the recess side wall 1142 at one side of the two opposite sides of the recess bottom wall 1141. For example, the light-emitter 1520 is mounted at the recess side wall 1142 at a lower side of the orientation illustrated in FIG. 15, and emits the light towards the recess side wall 1142 at another side of the two opposite sides of the recess bottom wall 1141 (a recess side wall 1142 at an upper side). The light emitted by the light-emitter 1520 is reflected by the recess side wall 1142 at the other side of the two opposite sides of the recess bottom wall 1141 (the recess side wall 1142 at the upper side) and passes through the light-transmitting cover 1510 to irradiate towards the first orientation. The light emitted by the light-emitter 1520 is further diverged after being reflected, improving light emitting uniformity of the light-transmitting cover 1510.

[0095] As illustrated in FIG. 1 to FIG. 7, in some embodiments, the duct housing 1100 includes a first housing 1120 and a mounting frame 1130. The mounting frame 1130 is connected to an inner wall of the first housing 1120 and surrounds the air inlet 1111. The light-transmitting cover 1510 connects to the mounting frame 1130 and defines the accommodation cavity 1530 together with the mounting frame 1130.

[0096] In an exemplary embodiment of the present disclosure, the first housing 1120 constitutes a majority of the duct housing 1100. The mounting frame 1130 is connected to an inner wall of an air inlet end of the first housing 1120. The light-transmitting cover 1510 is connected to the mounting frame 1130. The mounting frame 1130 and the first housing 1120, as independent components, are connected and fixed to each other by means of a connection method. By designing the mounting frame 1130 as an independent component, mounting of connection structures at the mounting frame 1130 can be facilitated, especially in a case where various types of connection structures are disposed at the mounting frame 1130. Compared to integral forming of the mounting frame 1130 and the first housing 1120, this embodiment can effectively reduce manufacturing complexity. Further, when it is necessary to mounted other parts to an inside of the first housing 1120, the mounting frame 1130 may be connected to the first housing 1120 after mounting of these parts, so as to avoid interference.

[0097] There are various ways to connect the mounting frame 1130 to the first housing 1120. For example, the mounting frame 1130 is snap-connected to the first housing 1120, which is quick and easy without direct manipulation by the user as long as the mounting frame 1130 is controlled to align with a corresponding position of the first housing 1120 to move into place until the snap-connection occurs. In addition, since the mounting frame 1130 is connected to the inner wall of the first housing 1120, the connection structures between the mounting frame 1130 and the first housing 1120 can be concealed once the snap-connection is performed, which can avoid exposure of a connection mechanism. Similarly, the light-transmitting cover 1510 may also be designed to be snap-connected to the mounting frame 1130.

[0098] As illustrated in FIG. 1 to FIG. 7, in some embodiments, the filter 1400 is connected to the mounting frame 1130. That is, both the light-transmitting cover 1510 and the filter 1400 need to be connected and fixed to the mounting frame 1130. Since the mounting frame 1130 is the independent component with respect to the first housing 1120, the mounting frame 1130 is easily designed with a connection structure configured to connect to the light-transmitting cover 1510 and a connection structure configured to connect to the filter 1400.

[0099] As illustrated in FIG. 5, FIG. 7, and FIG. 17, in some embodiments, the filter 1400 has an oil discharge opening 1428. The mounting frame 1130 has an oil relief port 1150. The oil discharge opening 1428 is inserted into the oil relief port 1150 to enable the oil discharge opening 1428 to be in communication with the oil relief port 1150. The filter 1400 discharges the filtered oil by the oil discharge opening 1428. Then, the oil is discharged from the main body 1000 by the oil relief port 1150. Through enabling the oil discharge opening 1428 to be inserted into the oil relief port 1150, positioning of the filter 1400 and discharging of the oil can be realized.

[0100] As illustrated in FIG. 18 to FIG. 20, in some embodiments, the filter 1400 includes a filter screen 1410 and a filter screen frame 1420. The filter screen frame 1420 has an oil collecting groove 1427. The oil discharge opening 1428 is disposed at the filter screen frame 1420. In addition, the oil discharge opening 1428 is in communication with the oil collecting groove 1427. The filter screen 1410 is disposed in the filter screen frame 1420 and located in the oil collecting groove 1427.

[0101] In an exemplary embodiment of the present disclosure, the filter screen frame 1420 is a skeleton structure of the filter 1400 and is configured to support the filter screen 1410. The filter screen 1410 is disposed at the filter screen frame 1420 to be supported. The filter screen 1410 has a porous structure, which can not only allow the fume to flow, but also filter the fume to obtain the oil. In this embodiment, the filter screen frame 1420 has the oil collecting groove 1427. In addition, the filter screen 1410 is located at the oil collecting groove 1427, and the filter screen 1410 is surrounded by the oil collecting groove 1427. When the filter screen 1410 filters the fume to obtain the oil, the oil flows along the filter screen 1410 until the oil enters the oil collecting groove 1427. By disposing of the oil collecting groove 1427, the oil separated from the filter screen 1410 is collected and then is discharged from the oil discharge opening 1428.

[0102] As illustrated in FIG. 18 to FIG. 20, in some embodiments, the filter screen frame 1420 includes a first frame 1421 and a second frame 1422. The first frame 1421 and the second frame 1422 are connected to each other to clamp the filter screen 1410, thereby supporting the filter screen 1410. In addition, after the first frame 1421 and the second frame 1422 are connected and fixed to each other, the oil collecting groove 1427 and the oil discharge opening 1428 are defined between the first frame 1421 and the second frame 1422. In this way, assembly between the filter screen frame 1420 and the filter screen 1410 can be facilitated on the basis of forming the oil collecting groove 1427 and the oil discharge opening 1428. For example, an assembly process between the filter screen frame 1420 and the filter screen 1410 is as follows: the filter screen 1410 is placed at the first frame 1421, and then the second frame 1422 is controlled to be connected to the first frame 1421. After the second frame 1422 and the first frame 1421 are connected and fixed to each other, the filter screen 1410 can be fixed and the oil collecting groove 1427 and the oil discharge opening 1428 can be defined, in this case the filter screen 1410 is located in the oil collecting groove 1427.
