Description

Technical Field

[0001] The invention relates to the technical field of fans, and in particular to a cooling and heating fan. Background Art

[0002] A cooling and heating fan is a fan with a heating function, which can meet the user's needs for blowing hot air in winter. A cooling and heating fan usually includes a shell, a heating element and a drive assembly. The drive assembly can drive the heating element to move radially along the shell away from the air duct, so that the heating element does not block the air duct, to ensure that the heating element does not affect the blowing effect in the normal blowing mode. In the prior art, the drive assembly includes a gear and a first rack that mesh with each other. The first rack is parallel to the radial direction of the shell. The gear is connected to the heating element through the first rack. The rotation of the gear drives the first rack to move radially along the shell, so that the first rack drives the heating element to move radially along the shell and away from the air duct. In order to ensure that the first rack has enough space to move in the radial direction of the shell, the radial dimension of the shell is usually designed to be relatively large, which will increase the overall size of the cooling and heating fan, and thus lead to high manufacturing costs of the cooling and heating fan. Summary of the invention

To this end, the present invention provides a cooling and heating fan, which has a relatively small overall size and is conducive to reducing the manufacturing cost of the cooling and heating fan.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] refer to Figures 1 to 4 The cooling and heating fan according to the embodiment of the present invention includes a housing 100, a fan blade 600, a heating component 200, a driving component 300 and a transmission member 400.

[0041] The housing 100 has an air duct 110, and the fan blade 600 is rotatably arranged in the air duct 110. The housing 100 has a first station and a second station, the first station is outside the air outlet range of the air duct 110, and the second station is within the air outlet range of the air duct 110. The heating component 200 is arranged in the housing 100, and the heating component 200 is configured to be movable in the housing 100 so that the heating component 200 can move to the first station or the second station. The driving component 300 is arranged in the housing 100, and the transmission member 400 can be bent. The output end of the driving component 300 is connected to the heating component 200 through the transmission member 400, and the driving component 300 can drive the heating component 200 to move toward the first station, so that the transmission member 400 can be bent, and the part of the transmission member 400 away from the heating component 200 moves in a direction not parallel to the radial direction of the housing 100.

[0042] In the embodiment of the present invention, the housing 100 is a cylindrical housing 100, and the cross section of the housing 100 along the direction perpendicular to the axis thereof is circular. The radial direction of the housing 100 is the direction perpendicular to the axis of the housing 100. The air duct 110 in the housing 100 is a cylindrical air duct 110, and the fan blades 600 are rotatably arranged in the air duct 110. After the user starts the cooling and heating fan, the fan blades 600 will rotate in the air duct 110 and generate wind, so that the air can be blown out of the air duct 110. The flow direction of the wind is the wind outlet direction, that is, Figure 1 The heating component 200 can move in the housing 100, and the heating component 200 itself can generate heat. The heating component 200 is arranged along the air outlet direction, so that after the heating component 200 approaches the air duct 110, the air blown out from the air duct 110 can pass through the heating component 200, so that the air blown out at last is hot air.

[0043] In an embodiment of the present invention, when the heating and cooling fans are in the heating mode, the heating component 200 moves to the second station; when the heating and cooling fans are in the normal mode, the heating component 200 moves to the first station. The first station is outside the air outlet range of the air duct 110, that is, the wind blown out from the air duct 110 will not pass through the first station area. When the heating component 200 is in the first station, the wind blown out from the air duct 110 will not flow through the heating component 200, that is, the heating component 200 does not affect the blowing effect. The second station is within the air outlet range of the air duct 110, that is, the wind blown out from the air duct 110 will pass through the second station area. When the heating component 200 is in the second station, the wind blown out from the air duct 110 will flow through the heating component 200, so that the blown wind is hot air.

[0044] The driving assembly 300 is installed in the housing 100, and the output end of the driving assembly 300 is connected to the heating assembly 200 through the transmission member 400, so that the driving assembly 300 can drive the heating assembly 200 to move in the housing 100, and then the heating assembly 200 can move to the first station or the second station. When the user starts the heating mode of the cooling and heating fan, the driving assembly 300 drives the heating assembly 200 to move to the second station, so that the wind blown out is hot wind. When the user turns off the heating mode, the driving assembly 300 drives the heating assembly to move to the first station, so that the wind blown out from the air duct 110 will not act on the heating assembly, so as to ensure that the heating assembly 200 does not affect the blowing effect. In an embodiment of the present invention, the transmission member 400 can be bent. Since the transmission member 400 is connected to the heating assembly 200, after the transmission member 400 is bent, the transmission member 400 can be divided into two parts, one of which is a part away from the heating assembly 200, and the other part is a part close to the heating assembly 200.

[0045] It is understandable that the transmission member 400 can be bent. When the user turns off the heating mode, the driving component 300 drives the heating component to move to the first station through the transmission member 400. In the process of the heating component moving toward the first station, the transmission member 400 begins to bend, and the part of the transmission member 400 away from the heating component 200 begins to move in a direction that is not parallel to the radial direction of the shell 100. Under the transmission action of the transmission member 400, the heating component can be moved to the first station to ensure that the heating component does not affect the blowing effect. In the process of the transmission member 400 driving the heating element to move, the moving direction of the part of the transmission member 400 away from the heating component 200 is not parallel to the radial direction of the shell 100, so that the shell 100 does not need to leave more radial space for the transmission member 400 to move, thereby making the radial size of the shell 100 can be designed to be smaller, so the overall size of the cooling and heating fan is reduced, which is conducive to reducing the manufacturing cost of the cooling and heating fan.

[0046] As an embodiment of the present invention, the transmission member 400 is a cable, and the driving assembly 300 includes a cable drum. The cable drum can be rotatably connected in the housing 100, one end of the cable is connected to the cable drum, and the other end of the cable is connected to the heating component 200, and the cable can be wound around the cable drum. When the user turns on the heating mode, the cable drum rotates and unwinds the cable, and the heating component 200 moves to the second station, so that the blown wind is hot air. When the user turns off the heating mode, the cable drum rotates and reels the cable, and the cable begins to bend, and the part of the cable away from the heating component 200 rotates around the axis of the cable drum, so that the part of the cable away from the heating component 200 is wound around the cable drum, and the other part of the cable is in a straight state, so that the cable pulls the heating component to move to the first station. The driving assembly 300 also includes a rotating motor, which is used to drive the cable drum to rotate.

[0047] As another embodiment of the present invention, the transmission member 400 is a steel ruler, and the driving assembly 300 includes a cable drum and a casing. The casing is arranged in the housing 100, and the cable drum can be rotatably connected in the casing. One end of the steel ruler is connected to the cable drum, and the other end of the steel ruler is connected to the heating component 200. The steel ruler can be wound on the cable drum, and the casing is provided with a hole for the steel ruler to move. When the user turns on the heating mode, the cable drum rotates and unwinds the steel ruler, and the heating component 200 moves to the second station, so that the blown wind is hot air. When the user turns off the heating mode, the cable drum rotates and rewinds the steel ruler, and the steel ruler bends, and the part of the steel ruler away from the heating component 200 rotates around the axis of the cable drum, so that the part of the steel ruler away from the heating component 200 is wound on the cable drum, and the other part of the steel ruler is in a straight state, so that the steel ruler pulls the heating component to move to the first station. The steel ruler and the drive assembly 300 together form a structure similar to a tape measure, which will not be further described here. The drive assembly 300 also includes a rotary motor, which is used to drive the cable drum to rotate.

[0048] refer to Figures 2 to 6 The driving component 300 includes a first rotating driving member 310 and a gear 320, the gear 320 is rotatably disposed in the housing 100, the transmission member 400 includes a plurality of first racks 410 hinged in sequence, the first racks 410 located at both ends of the transmission member 400 are respectively the first rack 410 at the head end and the first rack 410 at the end, the first rack 410 at the head end is connected to the heating component 200, the gear 320 can mesh with at least one first rack 410, the first rotating driving member 310 is used to drive the gear 320 to rotate, so that the first rack 410 away from the heating component 200 can move in a direction not parallel to the radial direction of the housing 100, and the first rack 410 close to the heating component 200 pulls the heating component 200 to move toward the first station. It can be understood that the transmission member 400 is formed by a plurality of first racks 410 hinged to each other, that is, the transmission member 400 is equivalent to a rack chain. Since any two adjacent first racks 410 are hinged to each other, the rack chain can be bent. The first rotation driving member 310 may be a first motor.

[0049] When the heating component 200 is located at the second station and when the user turns on the normal mode, the first rotating driving member 310 drives the gear 320 to rotate forward. Since the gear 320 can mesh with at least one first rack 410, the gear 320 can drive the multiple first racks 410 to move. Under the rotation of the gear 320, the transmission member 400 composed of the multiple first racks 410 begins to bend. At this time, the multiple first racks 410 can be divided into two parts, one part is the first rack 410 away from the heating component 200, and the other part is the first rack 410 close to the heating component 200. The rotation of the gear 320 can change the moving direction of the first rack 410, so that the part of the first rack 410 away from the heating component 200 begins to move in a direction that is not parallel to the radial direction of the housing 100, similar to the gear 320 winding up the multiple first racks 410. At this time, another part of the first rack 410 close to the heating component 200 starts to pull the heating component 200, so that the heating component 200 moves toward the first station and moves to the first station. When the heating component 200 is located at the first station and when the user turns on the heating mode, the first rotating drive member 310 drives the gear 320 to reverse, similar to the gear 320 unwinding multiple first racks 410, so that the heating component 200 can move toward the second station and move to the second station under its own gravity.

[0050] refer to Figures 4 to 8 and Fig.11 , a limiting protrusion 411 is provided on the side of the multiple first racks 410 away from the gear 320, and the limiting protrusion 411 can limit the relative rotation of two adjacent first racks 410, so that the other part of the first racks 410 close to the heating component 200 can be kept straight, and the first rotating driving member 310 is used to drive the gear 320 to rotate, so that the other part of the first racks 410 close to the heating component 200 can push the heating component 200 to move toward the second station. It can be understood that since the multiple first racks 410 are hinged to each other, the multiple first racks 410 can rotate relative to each other.

[0051] When the heating component 200 is located at the first station and the user turns on the heating mode, the first rotating driving member 310 drives the gear 320 to reverse. During the reversal of the gear 320, the other part of the first rack 410 close to the heating component 200, that is, the first rack 410 between the heating component 200 and the gear 320, has a tendency to swing toward the gear 320. The first racks 410 are provided with a limiting protrusion 411 on the side away from the gear 320. When the first racks 410 have a tendency to swing toward the direction of the gear 320, the limiting protrusion 411 can be against the adjacent first racks 410. The limiting protrusion 411 plays a limiting role at this time, avoiding relative rotation between the adjacent two first racks 410, thereby making the other part of the first rack 410 close to the heating component 200 in a straight state. The other part of the first rack 410 in a straight state plays a role in pushing the heating component 200, so that the heating component 200 can be pushed from the first station to the second station.

[0052] refer to Figure 7 and Figure 8 The transmission member 400 further includes a second rack 420, which is parallel to the radial direction of the housing 100, and is connected to the heating component 200. One end of the second rack 420 is hinged to the first rack 410 at the head end, and the second rack 420 can mesh with the gear 320. The limiting protrusion 411 on the first rack 410 at the head end can abut against the second rack 420 to limit the relative rotation between the second rack 420 and the first rack 410 at the head end. It can be understood that when the heating component 200 is located at the first station, the gear 320 and the second rack 420 remain in meshing state, and at this time, the multiple first racks 410 are away from the heating component 200. When the user turns on the heating mode, the first rotating drive member 310 drives the gear 320 to reverse, and the second rack 420 first starts to push the heating component 200 to move toward the second station. After the second rack 420 is disengaged from the gear 320, the gear 320 begins to mesh with the plurality of first racks 410 in sequence, so that the plurality of first racks 410 move in the direction of the second station in sequence, and under the action of the plurality of limiting protrusions 411, the second rack 420 and the plurality of first racks 410 can remain in a straight state and are parallel to the radial direction of the housing 100, so that the second rack 420 and the plurality of first racks 410 can push the heating component 200 to move to the second station. When the heating component 200 moves to the second station, the gear 320 stops rotating, and the gear 320 remains meshed with the first rack 410 at the end.

[0053] When the user turns on the normal mode, the first rotating drive member 310 drives the gear 320 to rotate forward, and the gear 320 begins to mesh with the multiple first racks 410 in sequence, so that the second rack 420 and the multiple first racks 410 pull the heating component 200 to move toward the first station. After the multiple first racks 410 are all disengaged from the meshing with the first rack 410, at this time, the multiple first racks 410 are not parallel to the radial direction of the housing 100, and the gear 320 begins to mesh with the second rack 420. Under the rotation of the gear 320, the second rack 420 continues to pull the heating component 200 to move to the first station. When the heating component 200 moves to the first station, the gear 320 stops rotating, and the gear 320 remains meshed with the second rack 420.

[0054] In the embodiment of the present invention, the transmission member 400 is composed of a second rack 420 and a plurality of first racks 410, and the length of the second rack 420 is greater than that of the first rack 410. On the one hand, the second rack 420 can reduce the number of the first racks 410, and the second rack 420 can serve as an additional support, so that the strength and rigidity of the entire transmission member 400 can be higher, and the stability of the transmission member 400 is improved. On the other hand, the second rack 420 is parallel to the radial direction of the housing 100 and is fixedly connected to the heating component 200. When the gear 320 is engaged with the second rack 420, the second rack 420 can provide a more stable pulling force or thrust for the movement of the heating component 200, so that the heating component 200 can move more smoothly.

[0055] In the embodiment of the present invention, reference Figure 2 and Figure 4 The cooling and heating fan includes two heating components 200 and two driving components 300. Two first stations and two second stations are arranged in the shell 100. The two heating components 200 can be moved to the two first stations respectively, so that the two heating components 200 are outside the air outlet range of the air duct 110 to ensure the air outlet effect of the cooling and heating fan. The two heating components 200 can be moved to the two second stations respectively, so that the two heating components 200 are within the air outlet range of the air duct 110, so that the blown wind is hot air. The two driving components 300 are respectively used to drive the two heating components 200 to move in the shell 100, so that the two heating components 200 can be moved to the two second stations or the two first stations respectively. The two heating components 200 are symmetrical up and down, and the two driving components 300 are rotationally symmetrical about the axis of the shell 100.

[0056] Here, one of the heating components 200 and the driving component 300 located at the bottom is used as an example. When the heating component 200 is located at the first station and the user turns on the heating mode, the first rotating driving member 310 drives the gear 320 to reverse, and the gear 320 is meshed with the second rack 420, and the second rack 420 pushes the heating component 200 to move toward the second station. After the second rack 420 is disengaged from the gear 320, the gear 320 begins to mesh with the first rack 410. The rotation of the gear 320 will cause the multiple first racks 410 to have a tendency to swing toward the gear 320, but under the action of the multiple limiting protrusions 411, the second rack 420 and the multiple first racks 410 cannot rotate relative to each other, so that the second rack 420 and the multiple first racks 410 between the heating component 200 and the gear 320 can remain in a straight state, that is, the second rack 420 and the multiple first racks 410 can play a role in pushing the heating component 200, and then the heating component 200 can be pushed from the first station to the second station. When the heating component 200 is located at the second station and the user turns on the normal mode, the second rack 420 and the multiple first racks 410 can pull the heating component 200 to the first station, which will not be further described here. It can be understood that, under the action of multiple limiting protrusions 411, no matter whether the heating component 200 is located above or below the shell 100, the transmission member 400 composed of the second rack 420 and multiple first racks 410 can pull or push the heating component 200 to move in the shell 100, so that the heating component 200 can move to the first station or the second station.

[0057] refer to Figure 5 , Fig. 9 and Fig.10, a linear guide groove 120 and an arc-shaped guide groove 130 are formed in the housing 100, and the linear guide groove 120 is parallel to the radial direction of the housing 100. The plurality of first racks 410 can move in the linear guide groove 120 and the arc-shaped guide groove 130, and the second rack 420 can move in the linear guide groove 120. It can be understood that the inner side walls of the linear guide groove 120 and the arc-shaped guide groove 130 can support and guide the movement of the plurality of first racks 410, so that the movement of the plurality of first racks 410 can be smoother and more stable. Similarly, the inner side walls of the linear guide groove 120 can support and guide the movement of the second rack 420, so that the movement of the second rack 420 can be smoother and more stable. In the embodiment of the present invention, when the heating component 200 moves from the second station to the first station, the plurality of first racks 410 first move in the linear guide groove 120 and then move into the arcuate guide groove 130, and the second racks 420 gradually move into the linear guide groove 120. When the heating component 200 moves to the first station, the plurality of first racks 410 are located in the arcuate guide groove 130, and the second racks 420 are completely located in the linear guide groove 120.

[0058] When the heating component 200 moves from the first station to the second station, the plurality of first racks 410 first move in the arc guide groove 130 and then move into the linear guide groove 120, and the second racks 420 gradually extend out of the linear guide groove 120. When the heating component 200 moves to the second station, part of the first racks 410 are located in the linear guide groove 120, another part of the first racks 410 are located outside the linear guide groove 120, and the second racks 420 are completely located outside the linear guide groove 120.

[0059] refer to Figure 4 , Figure 5 and Fig.11The cooling and heating fan also includes an auxiliary component 500, which is arranged in the housing 100. The output end of the auxiliary component 500 is connected to the terminal first rack 410. The auxiliary component 500 can provide a pulling force for the multiple first racks 410 so that a tension is maintained between any two adjacent first racks 410. It can be understood that, on the one hand, during the movement of the multiple first racks 410, the auxiliary component 500 can continuously provide a pulling force for the multiple first racks 410, so that a tension can be maintained between the multiple first racks 410 to ensure that the multiple first racks 410 will not shake during the movement, thereby making the movement of the heating component 200 more stable. On the other hand, during the process of the multiple first racks 410 pulling the heating component 200, the pulling force provided by the auxiliary component 500 can also assist the multiple first racks 410 in pulling the heating component 200. On the other hand, the pulling force provided by the auxiliary component 500 can maintain a tension wheel between the multiple first racks 410, thereby increasing the force between the first racks 410 and the gears 320, and effectively avoiding slippage between the first racks 410 and the gears 320.

[0060] refer to Figure 5 and Fig.11 The auxiliary assembly 500 includes an auxiliary belt 510, a reel 530 and a second rotary drive member 520. The reel 530 is rotatably connected to the housing 100. The output end of the second rotary drive member 520 is connected to the reel 530. One end of the auxiliary belt 510 is connected to the first rack 410 at the end, and the other end of the auxiliary belt 510 is connected to the reel 530. The auxiliary belt 510 can be wound around the reel 530. The second rotary drive member 520 is used to drive the reel 530 to rotate so that the auxiliary belt 510 unwound by the reel 530 can be tightened, and the auxiliary belt 510 can provide tension for the plurality of first racks 410. The second rotary drive member 520 can be a second motor.

[0061] It should be explained that the auxiliary belt 510 unwound by the reel 530 is the auxiliary belt 510 that is not wound on the reel 530. It is understandable that when the heating component 200 is in the second station and the user turns on the normal mode, the first rotary drive member 310 drives the gear 320 to rotate forward, and the second rotary drive member 520 drives the reel 530 to rotate forward, so that the reel 530 reels the auxiliary belt 510. In the process of the plurality of first racks 410 pulling the heating component 200, the reel 530 reels the auxiliary belt 510, so that the auxiliary belt 510 unwound by the reel 530 is in a straight state, and the auxiliary belt 510 in the straight state can provide tension for the plurality of first racks 410, so that the plurality of first racks 410 maintain tension, and the auxiliary belt 510 can also assist in pulling the heating component 200.

[0062] When the heating component 200 is in the first working position and the user turns on the heating mode, the first rotating driving member 310 drives the gear 320 to reverse, and the second rotating driving member 520 drives the reel 530 to reverse, so that the reel 530 unwinds the auxiliary belt 510. In the process of the plurality of first racks 410 pushing the heating component 200, the reel 530 unwinds the auxiliary belt 510, and the rotation speed of the reel 530 is lower than the rotation speed of the gear 320, so that the auxiliary belt 510 unwound by the reel 530 can be in a straight state. The auxiliary belt 510 in the straight state can provide tension for the plurality of first racks 410, so that tension is maintained between the plurality of first racks 410.

[0063] refer to Figure 7 and Figure 8 The heating component 200 includes a bracket 210 and a heating wire 220. The bracket 210 is movably connected to the housing 100 along the radial direction of the housing 100. The bracket 210 is connected to the output end of the driving component 300, and the heating wire 220 is arranged on the bracket 210. Under the action of the driving component 300, the bracket 210 can move between the first station and the second station, so that the bracket 210 can drive the heating wire 220 to move between the first station and the second station. In an embodiment of the present invention, the second rack 420 is connected to the bracket 210, and the bracket 210 and the heating wire 220 are both arc-shaped. The arc-shaped heating wire 220 can increase the contact area with the air to improve the heating effect of the cooling and heating fan.

[0064] The cooling and heating fan also includes two support plates 140, both of which are arranged in the housing 100, and the area between the two support plates 140 is used for the bracket 210 to move, and both of the two support plates 140 are against the bracket 210, so that the bracket 210 can move between the first station and the second station along the length direction of the support plate 140. It can be understood that the length direction of the support plate 140 is parallel to the radial direction of the housing 100, and the two support plates 140 play a supporting and guiding role in the radial movement of the bracket 210 along the housing 100, which, on the one hand, enables the bracket 210 to move along the radial direction of the housing 100, and on the other hand, ensures that the bracket 210 does not shake during the movement.

[0065] It should be explained that the bracket 210 and the two support plates 140 are in interference fit, that is, after the bracket 210 and the two support plates 140 are against each other, the bracket 210 can be fixed on the two support plates 140. Specifically, elastic paddles are also provided on both sides of the bracket 210, and the two elastic paddles can respectively against the two support plates 140 and undergo elastic deformation, so that the bracket 210 is fixed on the two support plates 140. As an embodiment of the present invention, the cooling and heating fan also includes two guide plates 150, and the two guide plates 150 are both arranged in the housing 100. Two limiting grooves are formed on both sides of the bracket 210, and the two guide plates 150 are both penetrated in the limiting grooves to prevent the bracket 210 from coming out from between the two support plates 140. Two limiting plates are also provided in the housing 100, and the two limiting plates can be against the bracket 210, so that the bracket 210 is stably in the second working position.

[0066] refer to Figure 4 and Figure 6 , a plurality of columnar protrusions 141 are provided on the support plate 140, and the plurality of columnar protrusions 141 are distributed along the length direction of the support plate 140. The support plate 140 abuts against the bracket 210 through the plurality of columnar protrusions 141 to reduce the contact area between the support plate 140 and the bracket 210. It can be understood that the cross section of the columnar protrusion 141 is semicircular, and the bracket 210 can abut against the arc outer wall of the columnar protrusion 141. The support plate 140 abuts against the bracket 210 through the plurality of columnar protrusions 141, thereby reducing the contact area between the support plate 140 and the bracket 210, thereby reducing the friction between the bracket 210 and the support plate 140, so as to reduce the wear between the bracket 210 and the support plate 140.

[0067] In an embodiment of the present invention, the cooling and heating fan also includes a front grille cover, a rear grille cover and a third motor. The front grille cover and the rear grille cover are respectively connected to the front and rear ends of the shell 100. The third motor is arranged in the shell 100. The output end of the third motor is connected to the fan blade 600. The third motor is used to drive the fan blade 600 to rotate, so that the fan blade 600 in the air duct 110 rotates and enables the air duct 110 to blow out wind.
