[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0040] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0041] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0042] In order to solve the problem of inconvenient conversion of hot and cold air in the conventional air cooler, the present invention provides a air cooler.

[0043] like Figure 1 As shown, the air duct includes a shell 10, a fan assembly 20 and a heater 30. The shell 10 has an air duct structure and a hot air side outlet 121 and a cold air side outlet 122 connected to the air duct structure. The fan assembly 20 is arranged in the air duct structure. The heater 30 is arranged at the end of the air duct structure and is located at the hot air side outlet 121. The air duct structure is formed by a fixed air duct wall 40 and a movable air duct wall 50. The movable air duct wall 50 is movably arranged in the shell 10 and has a first position for avoiding the hot air side outlet 121 and blocking the cold air side outlet 122. Correspondingly, the movable air duct wall 50 can also have a second position for avoiding the cold air side outlet 122 and blocking the hot air side outlet 121.

[0044] Through the above arrangement, the switching between cold air and hot air can be achieved only by the movement of the movable air duct wall. The structure is simple and the use is convenient and quick, which improves the user experience.

[0045] like Figure 1 、 Figure 6 、 Figure 8 and Figure 11 As shown, the housing 10 includes a rear housing 11, a panel 12, and a cover plate 13. The panel 12 has a hot air outlet 121 and a cold air outlet 122. The cover plate 13 is located between the panel 12 and the rear housing 11, forming a space for accommodating the air duct structure. The cover plate 13 is provided with a hot air communication port 131 and a cold air communication port 132, which correspond to the hot air outlet 121 and the cold air outlet 122, respectively. The heater 30 is disposed on the cover plate 13 and is located at the hot air communication port 131. The cover plate 13 is also provided with a fan inlet 133, which corresponds to the fan assembly 20.

[0046] In this embodiment, there are two air duct structures, which are arranged in parallel, and the ends of the two air duct structures are connected to the hot air outlet 121 and the cold air outlet 122 respectively. Among them, the movable air duct wall 50 of the two air duct structures is located between the fixed air duct walls 40 of the two air duct structures. In other words, the movable air duct wall 50 is located on the inner side of the air duct structure. Figure 1 As shown, the fan assembly 20 includes two fans 21, and the two fans 21 are respectively arranged in two air duct structures.

[0047] like Figures 1 to 2 、 Figure 5 、 Figure 7 and Figure 9 As shown, the air duct structure also includes two isolation air duct walls 60. The isolation air duct wall 60 is arranged between the two movable air duct walls 50 so that different surfaces of the isolation air duct wall 60 and the fixed air duct wall 40 on the corresponding side respectively constitute an air outlet channel, and the two isolation air duct walls 60 extend to the hot air side air outlet 121 and the cold air side air outlet 122 respectively. Furthermore, the two isolation air duct walls 60 are arranged at intervals so that there is a spare area between the two. Parts of the two movable air duct walls 50 are located in the spare area and pass through the spare area when switching between the first position and the second position. By providing the isolation air duct wall 60, the air outlet channels of the two fans 21 are separated, thereby preventing the airflows generated by the two fans 21 from affecting each other when they are in operation.

[0048] In this embodiment, the hot air outlet 121 and the cold air outlet 122 are located on opposite sides of the housing 10. The arrangement direction of the two fans 21 is perpendicular to the arrangement direction of the hot air outlet 121 and the cold air outlet 122. Specifically, the two fans 21 are arranged in a horizontal direction, and the hot air outlet 121 and the cold air outlet 122 are located on the upper and lower sides of the fan 21, respectively. Figure 1 Correspondingly, there are two fan air inlets 133 , and the two fan air inlets 133 are respectively provided corresponding to the two fans 21 .

[0049] like Figure 1 As shown, the air cooler further includes a driving unit 70. The driving unit 70 is drivingly connected to the two movable air duct walls 50.

[0050] In this embodiment, the driving unit 70 is a stepping motor.

[0051] In this embodiment, the air cooler further includes a transmission structure, and the driving unit 70 drives the two movable air duct walls 50 to move synchronously through the transmission structure. Figure 1 、 Figures 3 to 5 、 Figure 7 and Figure 9 As shown, the transmission structure includes a driving gear 80 and a rack belt 90. The driving gear 80 is disposed at the output end of the driving unit 70. Two rack belts 90 are meshed with each other. The two rack belts 90 are disposed on the two movable air duct walls 50, and the driving gear 80 meshes with one of the two rack belts 90. In other words, the driving unit 70 and the movable air duct wall 50 are meshed.

[0052] In this embodiment, the movable air duct wall 50 is arc-shaped, and the driving unit 70 drives the two movable air duct walls 50 to rotate. When the movable air duct wall 50 is in the first position and the second position, the ends of the arc are respectively connected with different positions of the fixed air duct wall 40 to close the hot air side outlet 121 or the cold air side outlet 122. Figures 3 to 5 、 Figure 7 and Figure 9 As shown, the two movable air duct walls 50 include a first movable air duct wall 51 and a second movable air duct wall 52. The rack belt 90 on the first movable air duct wall 51 is meshed with the driving gear 80, and the rack belt 90 on the second movable air duct wall 52 is meshed with the rack belt 90 on the first movable air duct wall 51. The driving unit 70 drives the driving gear 80 to rotate, thereby driving the first movable air duct wall 51 to rotate, and at the same time driving the second movable air duct wall 52 to rotate in the opposite direction. It can be understood that the rack belt 90 is located on the outer surface of the movable air duct wall 50. Among them, the meshing point of the first movable air duct wall 51 and the second movable air duct wall 52 and the driving gear 80 are all located in the empty area between the two isolation air duct walls 60. Of course, the rack belt 90 on the second movable air duct wall 52 can also be meshed with the driving gear 80, which can be selected according to actual needs.

[0053] In this embodiment, the middle portion of the isolation duct wall 60 is arc-shaped. When the movable duct wall 50 is in the first position, the first movable duct wall 51 and the second movable duct wall 52 respectively form a semi-closed circle with the middle portions of the fixed duct walls 40 on both sides, and the ends of the first movable duct wall 51 and the second movable duct wall 52 close to the hot air side outlet 121 respectively abut against the two fixed duct walls 40, and the end of the first movable duct wall 51 close to the cold air side outlet 122 is just located at the end of the isolation duct wall 60 close to the cold air side outlet 122, and the first movable duct wall 51 and the second movable duct wall 52 are engaged in the empty area between the two isolation duct walls 60 to block the empty area, thereby completely blocking the hot air side outlet 121 and just avoiding the cold air side outlet 122, so that the air duct can blow cold air outwards. Figure 5 shown.

[0054] When the movable air duct wall 50 switches from the first position to the second position, the driving part 70 drives the driving gear 80 to rotate in the counterclockwise direction, thereby driving the first movable air duct wall 51 to rotate in the clockwise direction, and at the same time drives the second movable air duct wall 52 to rotate in the counterclockwise direction, so that the first movable air duct wall 51 and the second movable air duct wall 52 are both close to the cold air side air outlet 122. When the movable air duct wall 50 is in the second position, the ends of the first movable air duct wall 51 and the second movable air duct wall 52 close to the cold air side outlet 122 are respectively abutted against the two fixed air duct walls 40, and the end of the first movable air duct wall 51 close to the hot air side outlet 121 is located at the end of the isolation air duct wall 60 close to the hot air side outlet 121, and the first movable air duct wall 51 and the second movable air duct wall 52 are engaged in the empty area between the two isolation air duct walls 60 to block the empty area, thereby completely blocking the cold air side outlet 122 and just avoiding the hot air side outlet 121, so that the air duct can blow hot air outwards. Figure 7 shown.

[0055] It should be noted that Figures 5 to 8 The arrow in the middle indicates the air outlet direction of the fan.

[0056] like Figure 2 、 Figure 5 、 Figure 7 、 Figures 9 to 11 As shown, the fan cooler also includes a guide rail 100. The guide rail 100 is arranged on the inner surface of the shell 10 and extends along the circumference of the fan assembly 20, and the movable air duct wall 50 moves along the guide rail 100. Specifically, the guide rail 100 includes two groups, each group consists of two, and the two guide rails 100 in each group are respectively arranged corresponding to the two movable air duct walls 50. One group of guide rails 100 is arranged on the inner bottom surface of the rear shell 11, and the other group of guide rails 100 is arranged on the cover plate 13, and the two groups of guide rails 100 are arranged correspondingly, and the upper and lower ends of the movable air duct wall 50 extend into the guide rails 100 on the rear shell 11 and the cover plate 13 respectively. It can be understood that in order to adapt to the arc shape of the movable air duct wall 50, the guide rail 100 is circular or arc-shaped.

[0057] Further, such as Figures 3 and 4 、 Figure 11 As shown, the movable air duct wall 50 is also provided with a sliding member 53. There are multiple sliding members 53, and the multiple sliding members 53 are arranged at intervals along the extension direction of the movable air duct wall 50. The sliding members 53 extend into the guide rail 100 so that the movable air duct wall 50 is slidably connected to the guide rail 100. Specifically, sliding members 53 are provided on the upper and lower end surfaces of the movable air duct wall 50. In this embodiment, the sliding members 53 are sliding balls. Through the above arrangement, the movable air duct wall 50 can rotate smoothly along the guide rail 100, thereby improving the cold and hot air switching efficiency of the air conditioner.

[0058] Figure 3 The figure shows the angle Q1 of the first movable air duct wall 51 and the angle Q2 of the second movable air duct wall 52. It is understood that Q1 and Q2 are the angles corresponding to the curvature of the first movable air duct wall 51 and the second movable air duct wall 52, respectively. In this embodiment, the angle Q1 of the first movable air duct wall 51 and the angle Q2 of the second movable air duct wall 52 satisfy the following: 10°≤Q1-Q2≤15°. The above range is the preferred angle range for the first movable air duct wall 51 and the second movable air duct wall 52. If the above range is exceeded, the contact position between the movable air duct wall 50 and the fixed air duct wall 40 in the first and second positions will be affected, thereby affecting the air outlet effect of the air outlet channel.

[0059] like Figure 5 The rotation angle Q3 of the first movable air duct wall 51 is shown. It can be understood that Q3 is the rotation angle when the first movable air duct wall 51 rotates from the first position to the second position. In this embodiment, the rotation angle Q3 of the first movable air duct wall 51 and the angle Q2 of the second movable air duct wall 52 satisfy: Q3 = Q2 / 2. In other words, the meshing angle between the first movable air duct wall 51 and the second movable air duct wall 52 is half of the angle Q2 of the second movable air duct wall 52. Through the above arrangement, the first movable air duct wall 51 and the second movable air duct wall 52 can be stably meshed without disengagement. In addition, the abutment position of the two end portions of the first movable air duct wall 51 and the fixed air duct wall 40 is determined by the rotation angle Q3 of the first movable air duct wall 51. The above arrangement also enables the two end portions of the first movable air duct wall 51 to have a suitable abutment position, making the overall structure of the air duct structure more reasonable.

[0060] In this embodiment, the gap between the other rack belt 90 of the two rack belts 90 and the driving gear 80 is greater than or equal to 2 mm. In other words, the gap between the rack belt 90 on the second movable air duct wall 52 and the driving gear 80 is greater than or equal to 2 mm. It should be noted that the above-mentioned gap refers to the distance between the rack belt 90 and the driving gear 80 on the line connecting the center of the driving gear 80 and the rotation center of the second movable air duct wall 52. In fact, the above-mentioned gap affects the center distance between the driving gear 80 and the second movable air duct wall 52, that is, the distance between the center of the driving gear 80 and the rotation center of the second movable air duct wall 52. Through the above-mentioned arrangement, interference between the driving gear 80 and the second movable air duct wall 52 is avoided due to tolerance in injection molding, thereby affecting the meshing transmission between the driving gear 80 and the first movable air duct wall 51.

[0061] Furthermore, to ensure the airflow guiding effect of the air outlet channel and avoid blocking the airflow and causing noise, the driving gear 80 has a range of installation positions, wherein the installation range has two end positions, namely, a first end position and a second end position. It will be understood that when the driving gear 80 is in the first end position, the gap between the rack belt 90 on the second movable air duct wall 52 and the driving gear 80 is 2 mm. When the driving gear 80 is in the second end position, the gap between the rack belt 90 on the second movable air duct wall 52 and the driving gear 80 is maximum. Figure 9 The figure shows the angle Q4 of the driving gear 80 between the first end point mounting position and the second end point mounting position relative to the rotation center of the first movable air duct wall 51. Specifically, Q4 is the angle between the center of the driving gear 80 and the line connecting the rotation center of the first movable air duct wall 51 when the driving gear 80 is respectively located at the first end point mounting position and the second end point mounting position. In this embodiment, Q4 satisfies: Q4≤Q1-Q2. Through the above-mentioned setting, the driving gear 80 has a reasonable installation position range and is compatible with the preferred angle range of the first movable air duct wall 51 and the second movable air duct wall 52, which can realize the driving of the first movable air duct wall 51 and form a closed air duct structure, thereby ensuring the air outlet effect of the air outlet channel.

[0062] In this embodiment, the heating element 30 is a PTC heating module. Furthermore, the PTC heating module is a plurality of PTC heating resistors, which are spaced apart within the hot air communication opening 131 of the cover plate 13. When the cool air blown by the fan 21 passes through the hot air communication opening 131, it is heated by the PTC heating resistors and converted into hot air, allowing the air cooler to blow out the hot air.

[0063] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: by setting up a ceiling fan including a shell 10, a fan assembly 20 and a heating element 30, the shell 10 has a duct structure and a hot air side air outlet 121 and a cold air side air outlet 122 connected to the duct structure, the fan assembly 20 is arranged in the duct structure, and the heating element 30 is arranged at the end of the duct structure and located at the hot air side air outlet 121, wherein the duct structure is formed by a fixed duct wall 40 and a movable duct wall 50, the movable duct wall 50 is movably arranged in the shell 10 and has a first position for avoiding the hot air side air outlet 121 and blocking the cold air side air outlet 122 and a second position for avoiding the cold air side air outlet 122 and blocking the hot air side outlet 121, so that the switching between cold air and hot air can be achieved only by the movement of the movable duct wall, the structure is simple, and the use is convenient and quick, which improves the user experience.
