Description

Technical Field

[0001] This utility model relates to an air conditioning device, and more particularly to a tower fan that can be used for both cooling and heating. Background Technology

[0002] Existing tower fans consist of a base and a cylindrical housing supported on the base. The heating element and impeller assembly are located inside the housing, and the display screen is usually located on the top of the housing. This means that the operating information of the tower fan, such as wind speed and temperature, can only be seen from the top of the housing. Since tower fans are generally quite tall, users often cannot see the operating information of the tower fan at a glance, which affects the user experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the above-mentioned deficiencies of the prior art by proposing a cooling and heating tower fan with a rotatable display screen on the top of the housing.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A tower fan for heating and cooling is provided, including a housing, a heating element assembly and a fan wheel assembly disposed within the housing. The fan wheel assembly includes a fan wheel, an air duct and a motor. The motor drives the fan wheel assembly to rotate and draw in airflow, which then passes through the heating element assembly along the air duct and is blown out. The fan also includes a rotatable display screen assembly disposed on the upper cover of the housing and a drive structure for driving the display screen assembly to rotate. Under the action of the drive structure, the display screen assembly rotates to protrude from the upper cover of the housing or rotates to be hidden inside the upper cover of the housing.

[0006] Furthermore:

[0007] The display assembly includes a display panel, a PCB display board, and a rotating box. The PCB display board is fixed inside the rotating box, the display panel is fastened to the rotating box, and the rotating box is rotatably disposed in a groove in the upper cover of the housing.

[0008] The drive structure includes a drive motor, a drive gear, and a driven gear. The drive gear is fixed to the output end of the drive motor, and the driven gear is fixed to the display screen. The drive motor drives the display screen assembly to rotate sequentially through the drive gear and the driven gear.

[0009] The groove at one end of the rotating shaft of the rotating box engages with the boss of the driven gear and is fixed by screws. The other end of the rotating shaft is connected to the rotating box by a locating pin.

[0010] The driving structure includes a torsion spring and a push-button door latch switch. The display screen is linked to the push-button door latch switch by means of the torsion spring. When the display panel is pressed, the push-button door latch switch is triggered, and the rebound force of the torsion spring is used to realize the flipping of the display screen assembly.

[0011] The rotating box is equipped with a torsion spring bracket, and torsion springs and rotating shafts are installed on both the left and right sides of the torsion spring bracket. The two ends of the torsion spring have bent parts, with the inner end inserted into the limiting post of the torsion spring bracket and the outer end inserted into the positioning post of the rotating shaft. The positioning plate of the rotating shaft is inserted into the positioning hole of the housing cover.

[0012] The upper cover is provided with a limiting structure to fix the display screen assembly in its usage state.

[0013] Compared with the prior art, the present invention has the following advantages: the upper cover of the housing is designed with a flip-out display screen that can be rotated and protruded from the upper cover of the housing as needed. When the display screen is rotated and protruded from the upper cover of the housing, it is convenient for users to read the working information of the tower fan. When the display screen is rotated and hidden inside the upper cover of the housing, it can keep the appearance of the fan simple and avoid dust accumulation or damage from bumps.

[0027] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Embodiment 1 of the cooling and heating tower fan of this utility model, as follows: Figure 1-7 As shown, it includes a base 17 and a housing supported on the base 17, as well as a heating element assembly and a fan assembly disposed within the housing. Figure 3 As shown, the housing consists of a front panel 11, a rear panel 12, a left panel 13, a right panel 14, a top cover 15, and a bottom cover 16.

[0029] The upper cover 15 of the housing is provided with a display screen assembly 4 and a display screen driving structure 5, such as Figure 4 , Figure 5 and Figure 7 As shown. The display screen assembly 4 includes a display panel 42, a PCB display board 43, and a rotating box 44. The PCB display board 43 is fixed inside the rotating box 44, and the display panel 42 is fastened to the rotating box 44. The rotating box 44 is rotatably disposed in a groove in the upper cover of the housing. The drive structure 5 includes a motor bracket 51, a drive motor 53, a drive gear 52, and a driven gear 45. The groove at one end of the rotating shaft 41 of the rotating box 44 engages with the boss of the driven gear 45 and is fixed by screws. The other end of the rotating shaft 41 is connected to the rotating box 44 by a locating pin.

[0030] When the drive motor 53 is working, the drive gear 52 drives the driven gear 45 through the meshing of the teeth; when the driven gear 45 rotates, the rotating shaft 41 will rotate along with it (the rotating shaft is integrally formed with the rotating box or fixed as one piece), so the rotating box will also rotate, that is, the entire display screen assembly 4 rotates.

[0031] The display screen rotates and protrudes from the top cover of the housing, allowing users to easily read information such as wind speed, timer, and temperature, providing convenience. After use, the display screen rotates and retracts into the top cover of the housing under the action of the drive structure.

[0032] like Figure 4 As shown, the interior of the housing, from front to back, consists of a heating element assembly 2 and a fan assembly 3. The fan assembly 3 includes a pressure plate 31, a cross-flow fan 32, an air duct 33, a fan bracket 34, a motor 35, and a motor bracket 36. The heating element assembly 2 includes a fuse 21, a heating element bracket 22, and a heating element 23. After power-on, the motor 35 drives the cross-flow fan 32 to rotate. The cross-flow fan 32 draws in air from the air inlet, then along the air duct 33, through the heating element assembly 5, and out through the air outlet 111. When heating, the heating element 23 operates, and the air blown out by the cross-flow fan 32 passes through the heating element 23, carrying away its heat, and finally, warm air is blown out through the air outlet 111. When cold air is needed, the heating element 23 does not operate, and the cross-flow fan blows out cold air. This achieves both heating and cooling in different modes.

[0033] like Figure 3 As shown, a high-temperature resistant air outlet grille 111 is provided on the front panel 11 to prevent the airflow from deforming the air outlet position during heating mode. A detachable dust filter 121 and filter support 122 are provided at the air inlet of the rear panel 12. The filter can block dust, hair, fibers and other particles in the air from entering the machine and prevent them from adhering to the heating element or fan wheel, thereby reducing problems such as decreased efficiency and increased operating noise caused by dust accumulation.

[0034] Embodiment 2 of the cooling and heating tower fan of this utility model, as follows: Figures 1-2 , Figures 8-13 As shown, it includes a base 17' and a housing supported on the base 17', as well as a heating element assembly and a fan assembly disposed within the housing. Figure 8 As shown, the housing consists of a front panel 11', a rear panel 12', a left panel 13', a right panel 14', a top cover 15', and a bottom cover 16'.

[0035] like Figure 13 , Figures 8 to 10 As shown, the upper cover 15' in the housing is provided with a flip-up display screen assembly 4'.

[0036] The display screen assembly includes a display panel 41', a PCB display board 42', and a rotating box 46'. The PCB display board 42' is fixed inside the rotating box 46', and the display panel 41' is fastened to the rotating box 46'. The rotating box 46' is rotatably disposed in a groove in the upper cover of the housing.

[0037] The driving structure includes a torsion spring 44' and a push-button door latch switch. The display screen is linked to the push-button door latch switch by means of the torsion spring. When the display panel is pressed, the push-button door latch switch is triggered, and the display screen assembly is flipped by the rebound force of the torsion spring.

[0038] Specifically, a torsion spring bracket 43' is provided inside the rotating box 46'. Torsion springs 44' and rotating shafts 45' are mounted on both sides of the torsion spring bracket 43'. The torsion springs 44' have bent ends; their inner ends are inserted into the limiting posts 431' of the torsion spring bracket, and their outer ends are inserted into the positioning posts 451' of the rotating shaft 45'. The positioning piece 452' of the rotating shaft 45' is inserted into the positioning hole of the housing cover. After the torsion springs are pre-tightened, they generate a restoring force. The outer end of the torsion spring is fixed to the rotating shaft on the cover. When the push-button latch is opened, the restoring force of the torsion spring causes the torsion spring bracket to rotate. The torsion spring bracket and the rotating box are fixed together, ultimately causing the display screen to flip.

[0039] The rotating housing 46' is equipped with a downward protrusion device 461', and the upper cover 15' is equipped with a push-button latch switch 151'. When the display screen is placed on the upper cover 15', the protrusion device 461' and the push-button latch switch 151' are self-locking and fixed. When using the machine, the push-button latch switch 151' is opened by pressing the display panel 41'. After the switch is opened, the return force of the torsion spring 44' causes the display screen to rotate upwards. Furthermore, to prevent the rotating housing from continuing to rotate after reaching a designated position, a limit structure 152' is provided on the upper cover 15'. After rotating to the designated position, the elastic force of the torsion spring causes the display screen to protrude from the top surface of the housing, and the limit structure 152' maintains this state and prevents it from falling off naturally. When turning off the machine, pressing the display panel 41' again will cause the push-button latch switch 151' to self-lock, allowing the display screen assembly to lie flat for easy storage and movement of the machine. See [link to product details] Figures 10-13 Because the torsion spring has a restoring force, the rotating box will not fall down on its own.

[0040] The interior of the housing, from front to back, consists of a heating element assembly 2' and a fan assembly 3', as follows: Figure 9 and Figure 10 As shown. The impeller assembly includes a wind pressure plate 31', a flow impeller 32', an air duct 33', an impeller bracket 34', a motor 35', and a motor bracket 36'. After the machine is turned on, the motor drives the flow impeller, which draws in air from the air inlet, passes through the heating element assembly 5' along the air duct, and then blows it out from the air outlet grille 111'.

[0041] The heating element assembly includes a fuse 21', a heating element bracket 22', and a heating element 23'. When heating, the heating element 23' operates; the air blown by the cross-flow fan passes through the heating element and carries away its heat, finally exiting as warm air through the air outlet grille. When cold air is needed, the heating element 23' does not operate, and the cross-flow fan blows out cold air; thus achieving dual-use (heating and cooling) in different modes.

[0042] like Figure 8 As shown, a high-temperature resistant air outlet grille 111' is provided on the front panel 11' to prevent deformation of the air outlet position under high temperatures; a detachable dust filter 121' and filter support 122' are provided at the air inlet of the rear panel 12'. The filter can block dust, hair, fibers and other particles in the air from entering the machine and prevent them from adhering to the heating element or the impeller. This can reduce problems such as decreased efficiency and increased operating noise caused by dust accumulation.

[0043] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and these modifications and substitutions should all fall within the protection scope of the appended claims of this utility model.
