[0042] With the improvement of living standards, people's functional requirements for air conditioners are becoming more and more diverse. Among them, the zoned air supply function is welcomed by the market because it can provide customized comfort adjustment according to the needs of different regions.

[0043] Existing air conditioners usually adopt a single air outlet. By swinging the louvers at the air outlet, the air temperature control in a specific area can be achieved to a certain extent, or two independent air outlets are equipped to control the air temperature in the left and right areas. However, there is still a problem of insufficient zoning fineness, which is difficult to meet the requirements of complex or changing indoor environments, resulting in certain limitations in the air conditioner's realization of zoned air temperature control.

[0044] To solve this technical problem, the present utility model proposes an air conditioner.

[0045] Please refer to Figures 1 to 9 In an embodiment of the present utility model, the air conditioner includes a housing 10 and a air supply assembly 20. The housing 10 includes an upper air outlet 101 and a lower air outlet 102; the air supply assembly 20 is disposed inside the housing 10. The air supply assembly 20 includes an upper air supply module 21 and a lower air supply module 22 arranged up and down. The lower air supply module 22 communicates with the lower air outlet 102; wherein, there are at least two upper air outlets 101. The upper air supply module 21 includes at least two upper fans 212 corresponding to the upper air outlets 101. The upper fans 212 communicate with the upper air outlets 101 through upper air ducts 211; so as to realize independent adjustment of air supply and temperature control in multiple indoor areas, and further meet the air temperature requirements of different people.

[0046] In the technical solution of the present utility model, through the independent arrangement of the upper air supply module 21 and the lower air supply module 22, combined with the up-and-down arrangement of the upper air outlet 101 and the lower air outlet 102, when the upper air supply module 21 and the lower air supply module 22 are turned on simultaneously or separately, the air conditioner can realize air supply and temperature control in different indoor areas. Among them, there are at least two upper air outlets 101, and each upper air outlet 101 is equipped with an upper fan 212. In this way, the air conditioner can further realize air supply and temperature control in different indoor areas by turning on each upper fan 212 simultaneously or separately, and form a more refined partition temperature control adjustment, improve the adjustment flexibility of the air conditioner, and at the same time, meet the specific needs of different users at different times and in different occasions, and improve the comfort of users.

[0047] It should be noted that both the upper air supply module 21 and the lower air supply module 22 can inhale indoor air and perform heat exchange through a heat exchanger, and then send the processed air back into the room through the upper air outlet 101 and the lower air outlet 102 to achieve cooling and heating adjustment of the indoor environmental temperature. Among them, when the upper air supply module 21 and the lower air supply module 22 work simultaneously, it helps to enhance the cooling and heating effect. The air conditioner can be a floor-standing air conditioner. At this time, the up-and-down direction is the standing direction of the air conditioner.

[0048] In addition, when the air conditioner has a fresh air function and / or a purification function, the lower air outlet 102 can be compatible with the air outlet when the function is turned on, which is convenient for providing fresh air and clean air to the room, improving the comfort of the indoor environment. At the same time, it reduces the need to separately set air outlets for each function, simplifies the structure of the housing 10, saves layout space, and improves the practicability and flexibility of the air conditioner.

[0049] Optionally, in an embodiment of the present utility model, the air conditioner further includes a damper 31 rotatably disposed in the upper air duct 211 for adjusting the opening degree of the upper air outlet 101. That is, the opening degree of the upper air outlet 101 can be arbitrary, and the upper air outlet 101 is closed when the damper 31 completely covers the upper air outlet 101, and the opening degree is 0°. The upper air outlet 101 is opened when an air passing gap is formed between one side of the damper 31 and the side edge of the upper air outlet 101, where the side edge can be the left side edge or the right side edge of the upper air outlet 101.

[0050] Taking the case where there are two upper air outlets 101 as an example, since the upper air outlet 101 is connected to the upper fan 212 through the upper air duct 211, the upper fan 212 and the damper 31 in the corresponding upper air duct 211 can be controlled to be linked. That is, when the upper fan 212 is turned on, the damper 31 opens the upper air outlet 101. In this way, on the basis of meeting the air temperature requirements of different regions, the energy use is optimized and the energy consumption is reduced.

[0051] Since there are at least two upper air outlets 101, optionally, in an embodiment of the present utility model, the opening degrees of the upper air outlets 101 are the same or different. It can be understood that, as Figure 5 shown, the opening degrees of the two upper air outlets 101 are different. At this time, one upper air outlet 101 is closed and the other upper air outlet 101 is opened, so as to control the air supply temperature of a specific region; as Figure 6 shown, limited by the symmetrical distribution of the two upper air outlets 101 in the width of the air conditioner, when the opening degrees of the two upper air outlets 101 are the same, after the two dampers 31 rotate in the same direction, an air passing gap formed between one side of the damper 31 and the side edge of the upper air outlet 101 will make the extension lines of the air flow directions blown out by the two upper air outlets 101 intersect to control the air supply temperature of a specific region; when the two dampers 31 rotate in opposite directions, an air passing gap formed between one side of the damper 31 and the side edge of the upper air outlet 101 will make the air flow directions blown out by the two upper air outlets 101 parallel, and concentrate on controlling the air supply temperature of a certain region, so as to form a more refined zoning temperature control adjustment, which is convenient to improve the adjustment flexibility of the air conditioner. Furthermore, it can meet the specific needs of different users at different times and in different situations, and improve the comfort of users. However, in other embodiments, the two upper air outlets 101 are opened simultaneously, and the opening degrees of the two upper air outlets 101 are set differently.

[0052] Optionally, in an embodiment of the present utility model, the air conditioner further includes a switch driving member 32 rotatably connected to the air door 31. The switch driving member 32 is installed in the housing 10. Further, by controlling the opening and closing of the switch driving member 32, the rotation of the air door 31 is controlled. Thus, in cooperation with the opening and closing of the corresponding upper blower 212, the air supply temperature control of the indoor environment is realized, and the comfort of the user in the room is improved. Among them, in the up and down direction of the air conditioner, the two ends of the air door 31 are provided with rotating shafts that can cooperate with the fixed structure in the housing 10, so that when the switch driving member 32 drives the air door 31 to rotate, the air door 31 rotates around the rotating shaft to realize the opening and closing of the upper air outlet 101.

[0053] Please refer to Figures 5 to 7 , in an embodiment of the present utility model, the channel wall of the upper air duct 211 is provided with a guiding track 214 that cooperates with the air door 31. With such a setting, it helps to increase the effective contact area between the air door 31 and the channel wall, improve the movement stability of the air door 31, and facilitate the installation and positioning of the air door 31 in the upper air duct 211, thereby improving the assembly efficiency of the air door 31. Among them, the guiding track 214 can be configured as a guiding track 214 protruding from the channel wall, which is convenient for the air door 31 to abut against the guiding track. At this time, the air door 31 can be formed with a protrusion or groove that cooperates with the guiding track 214.

[0054] Please refer to Figures 2 to 4 , in an embodiment of the present utility model, the air conditioner further includes a wind guiding structure 40. The wind guiding structure 40 is disposed at at least one of the air door 31 and the lower air outlet 102 for adjusting the air outlet direction of the air conditioner. In this way, the air flow directions at the upper air outlet 101 and the lower air outlet 102 can be adjusted. Further, more refined zoning air supply temperature control can be performed in a specific area, further improving the adjustment flexibility of the air conditioner, and at the same time, meeting the specific needs of different users at different times and in different situations, and improving the comfort of the users.

[0055] Specifically, in the embodiment of the present utility model, the air guiding structure 40 includes air guiding plates 41 and a swing driving member 44. A plurality of the air guiding plates 41 are arranged along the up-and-down direction of the air conditioner. Each of the air guiding plates 41 is connected by a connecting rod 42, and the connecting rod 42 is connected to the swing driving member 44 to drive each of the air guiding plates 41 to swing up and down. It can be understood that an installation plate is arranged on one side of the air damper 31 facing the upper air duct 211. One end of each air guiding plate 41 is movably connected to the installation plate, and the other end extends into the upper air duct 211. Among them, each of the air guiding plates 41 is connected by the connecting rod 42, and the connecting rod 42 is connected to the swing driving member 44. Thus, when the swing driving member 44 drives the connecting rod 42 to move up and down, each of the air guiding plates 41 swings up and down under the drive of the connecting rod 42. Furthermore, the air passing through the air guiding structure 40 can be guided upward or downward to meet the specific needs of different users at different times and in different scenarios. However, in other embodiments, adjacent two air guiding plates 41 are connected by the connecting rod 42, and one of the air guiding plates 41 is configured as a main air guiding plate 41. The main air guiding plate 41 is connected to the swing driving member 44, and can also drive each of the air guiding plates 41 to swing up and down. The swing driving member 44 can be configured as a telescopic rotary motor.

[0056] Please refer to Figure 2 , in the embodiment of the present utility model, the air guiding structure 40 is installed on one side of the air damper 31 facing the upper air supply module 21. Thus, when the upper air outlet 101 is opened, the air guiding structure 40 rotates with the rotation of the air damper 31. Furthermore, when the air blown from the upper blower 212 to the upper air outlet 101 flows through the air damper 31, as the swinging posture of the air guiding plate 41 changes, the air flow direction will change accordingly, so as to improve the diversification of the air outlet angles in the same air supply temperature control area, which helps to further subdivide this area, so that more refined zoning air supply temperature control can be carried out in the specific area, further improving the adjustment flexibility of the air conditioner, and at the same time, meeting the specific needs of different users at different times and in different scenarios, and improving the comfort of users.

[0057] Please refer to Figure 5 , in the embodiment of the present utility model, a limiting stopper 213 is arranged in the upper air duct 211. The limiting stopper 213 is used to restrict the closing tendency of the air guiding structure 40 and / or the air damper 31. With such a setting, the energy consumption caused by the excessive rotation of the air damper 31 is effectively reduced, and it also helps to improve the opening and closing efficiency of the upper air outlet 101.

[0058] Among them, the limit stop 213 is located on the path where the air damper 31 closes the upper air outlet 101, that is, it is arranged at the limit position where the air damper 31 closes, which can ensure the reliable closing of the upper air outlet 101 by the air damper 31, improve the accuracy of the air damper 31 closing the upper air outlet 101. At the same time, the upper air outlet 101 can be closed with a shorter stroke, improving the opening and closing efficiency of the upper air outlet 101. The limit stop 213 can be configured as a baffle protruding from the channel wall of the upper air duct 211, used to abut and stop the air deflector 41 to restrict the continuous rotation of the air damper 31, and can also be used to directly abut and stop the air damper 31 to restrict the continuous rotation of the air damper 31; the limit stop 213 is also arranged close to the rotating shaft on the air damper 31; furthermore, in cooperation with the corresponding sensor, the response efficiency of the switch driving member 32 to stop the rotation of the air damper 31 can be improved.

[0059] Please refer to Figure 3 , in the embodiment of the present utility model, the air guiding structure 40 is arranged in the lower air duct 221 of the lower air supply module 22. At this time, the air guiding structure 40 is directly fixed to the channel wall of the lower air duct 221 and is located between the lower air outlet 102 and the lower blower 222, that is, the air deflector 41 is movably connected to the channel wall of the lower air duct 221. In this way, when the air blown out by the lower blower 222 flows through the air guiding structure 40, as the swinging posture of the air deflector 41 changes, the flow direction of the air blown to the lower air outlet 102 will change accordingly, so as to improve the diversification of the air outlet angles in the same air supply temperature control area, which helps to further subdivide this area, so that more refined zoning air supply temperature control can be carried out in a specific area, further improving the adjustment flexibility of the air conditioner. At the same time, it can meet the specific needs of different users at different times and in different occasions, improving the comfort of users.

[0060] Furthermore, in the embodiment of the present utility model, the air guiding structure 40 further includes an extension plate 43 connected to the air deflector 41, and the free end of the extension plate 43 is spaced from the air duct wall of the lower air duct 221. Such a setting ensures that the air blown out by the lower blower 222 can be redirected under the action of the air guiding structure 40. Furthermore, it ensures that the air at the lower air outlet 102 is integrated to control the air supply temperature of a certain area, improving the utilization rate of air, accelerating the rapid control of the air temperature in this area, improving the adjustment reliability of the air conditioner. At the same time, it can meet the specific needs of different users at different times and in different occasions, improving the comfort of users.

[0061] The connection method between the extension plate 43 and the air deflector 41 includes but is not limited to integral molding, welding, and splicing to ensure the reliable use of the air guiding structure 40; and the free section of the extension plate 43 is spaced from the air duct wall of the lower air duct 221, which helps to reduce the possibility of interference between the air guiding structure 40 and the air duct wall of the lower air duct 221, further improving the service life and use reliability of the air guiding structure 40.

[0062] Please refer to Figure 3 , in the embodiment of the present utility model, the lower air supply module 22 includes two lower air ducts 221, the lower air ducts 221 are communicated with the lower air outlet 102, and a lower air blower 222 is arranged at the intersection of the two lower air ducts 221. In this way, the two lower air ducts 221 are powered by one lower air blower 222 at the same time. On the one hand, the structure of the lower air supply module 22 is simplified, and the occupied space of the lower air supply module 22 in the housing 10 is small, which is convenient for assembling the lower air supply module 22 in a limited space. On the other hand, the number of lower air blowers 222 is small, which helps to reduce the overall noise level of the lower air supply module 22; at the same time, it also helps to reduce the overall cost of the air conditioner. And the lower air blower 222 is arranged at the intersection of the two lower air ducts 221, which is convenient for simultaneously controlling the air volume at the two lower air outlets 102 and improving the efficiency. However, in other embodiments, there are two lower air blowers 222, which are respectively and correspondingly communicated with the two lower air outlets 102.

[0063] Optionally, in the embodiment of the present utility model, both the upper air blower 212 and the lower air blower 222 are configured as cross-flow blowers; it can be understood that the upper air supply module 21 uses two independent cross-flow blowers to communicate with the two upper air outlets 101 through two independent upper air ducts 211. On the one hand, a larger air supply volume can be provided to the upper area of the room, which is convenient for improving the refrigeration and heating capacity of the air conditioner. On the other hand, since one cross-flow blower corresponds to one upper air duct 211, it helps to reduce the reflection and resonance of air in the upper air duct 211 and reduce the noise.

[0064] The lower air supply module 22 uses one cross-flow blower to communicate with the two lower air outlets 102 through two connected lower air ducts 221. On the one hand, the number of lower air blowers 222 is small, which helps to reduce the overall noise level of the lower air supply module 22. On the other hand, it is convenient to uniformly control the two lower air ducts 221 through one lower air blower 222, which is convenient for later maintenance and also helps to reduce the overall cost.

[0065] Optionally, in the embodiment of the present utility model, the housing 10 further includes a grille 50 arranged at the lower air outlet 102. On the one hand, it effectively prevents foreign objects from entering the interior of the air conditioner, improves the use reliability and safety of the air conditioner, and reduces potential safety hazards; on the other hand, it can guide the air flow to a specific area to a certain extent, which helps to more evenly distribute the cold and hot air. The grille 50 and the housing 10 can be integrally formed to improve the overall structural strength; the grille 50 and the housing 10 can also be detachably connected for disassembly, installation and cleaning.

[0066] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
