[0055] This invention proposes a floor-standing air conditioner indoor unit.

[0056] Reference Figures 1 to 18 In this embodiment of the invention, the floor-standing air conditioner indoor unit includes a housing 10, a first air supply module 20, a converter module 40, and a second air supply module 30. The housing 10 has an indoor air inlet 11 and an outdoor air inlet 12. The first air supply module 20 and the converter module 40 are built into the housing 10. The converter module 40 is connected to the first air supply inlet 23 of the first air supply module 20 and is used to guide at least part of the airflow passing through the indoor air inlet 11 or the airflow passing through the outdoor air inlet 12 into the first air supply module 20. The first air supply module 20 is used to blow the airflow into the room. The second air supply module 30 is built into the housing 10 and is used to blow at least part of the airflow passing through the indoor air inlet 11 into the room. In this way, the overall size of the indoor unit can be reduced while meeting the air supply requirements of different modes.

[0057] The housing 10 includes a front panel assembly 14 and a back panel assembly 15. The front panel assembly 14 has a main air outlet 13 for delivering airflow into the room. The main air outlet 13 may be equipped with an air outlet grille 141 to prevent damage to the internal components of the housing 10 by foreign objects during use. The back panel assembly 15 has an indoor air inlet 11 connecting to the room for treating indoor air, and an outdoor air inlet 12 connecting to the outside to keep the indoor environment fresh and improve user comfort. The indoor air inlet 11 and the outdoor air inlet 12 may be equipped with corresponding air inlet grilles 151 to reduce debris entering the housing 10 through the indoor air inlet 11 and the outdoor air inlet 12. The floor-standing air conditioner indoor unit also includes a chassis 80 for supporting and fixing the housing 10.

[0058] The outer casing 10 houses a first air supply module 20 and a second air supply module 30. The coordinated arrangement of the first and second air supply modules 20 ensures sufficient airflow to the indoor unit, reducing limitations imposed by the size of individual air supply modules and their outlets. Simultaneously, utilizing the converter module 40 connected to the first air inlet 23 of the first air supply module 20, the first air supply module 20 can selectively connect to either the indoor air inlet 11 or the outdoor air inlet 12. This allows at least a portion of the airflow passing through the indoor air inlet 11 or the outdoor air inlet 12 to be delivered indoors via the first air supply module 20. Different air supply modes can be formed. For example, the first air supply module 20 and the second air supply module 30 can simultaneously deliver airflow through the indoor air inlet 11 to the room, or the first air supply module 20 can deliver airflow through the outdoor air inlet 12 to the room, and the second air supply module 30 can deliver airflow through the indoor air inlet 11 to the room. With this configuration, on the one hand, the overall size of the indoor unit can be reduced while meeting the air supply requirements of different modes, and the adaptability of the indoor unit can be improved. On the other hand, during use, users can switch between different modes according to their needs, thereby meeting their different air supply requirements and improving user comfort.

[0059] In addition, the first air outlet 24 of the first air supply module 20 and the second air outlet 34 of the second air supply module 30 may differ in height and / or width, which can improve the size of the delivery area while meeting the air supply volume requirements, thereby allowing for multi-directional fine adjustment of air volume and windless feeling, and improving user comfort.

[0060] The technical solution of this invention provides a converter module 40 at the first air inlet 23 of the first air supply module 20, enabling the first air supply module 20 to selectively connect to either the indoor air inlet 11 or the outdoor air inlet 12. This allows at least a portion of the airflow passing through the indoor air inlet 11 or the airflow passing through the outdoor air inlet 12 to be delivered to the room via the first air supply module 20, thus forming air supply in different modes. This configuration, on the one hand, can meet the air supply requirements of different modes while reducing the overall size of the indoor unit and improving the adaptability of the indoor unit. On the other hand, users can switch between different modes according to their needs during use, thereby meeting their different air supply requirements and improving user comfort.

[0061] Reference Figures 13 to 18In one embodiment, the air exchange module 40 includes a fresh air housing 41, an air exchange door 46, and a first motor 47. The fresh air housing 41 is connected to the first air supply module 20 to restrict the fresh air passage 42 and the guide passage 43. The fresh air passage 42 is provided with a fresh air inlet 4111 that can communicate with the outdoor air inlet 12. The guide passage 43 communicates with the fresh air passage 42 and with the first air supply inlet 23. The air exchange door 46 is rotatably connected to the fresh air housing 41. The first motor 47 drives the air exchange door 46 and causes the air exchange door 46 to block either the guide passage 43 or the fresh air passage 42 from communicating with the indoor air inlet 11, or either of them can communicate with the indoor air inlet 11. Under the drive of the first motor 47, the air exchange door 46 rotates inside the fresh air housing 41, blocking either the guide passage 43 or the fresh air passage 42 from communicating with the indoor air inlet 11. When the indoor air inlet 11 is connected, the first air supply module 20 and the second air supply module 30 are set independently. The first air supply module 20 can only deliver airflow passing through the outdoor air inlet 12 to the room. That is, the fresh air inlet 4111 is opened and connected to the outdoor air inlet 12 to introduce fresh air into the room and improve indoor air quality. When the fresh air channel 42 is connected, part of the airflow passing through the indoor air inlet 11 can flow through the fresh air channel 42 to the first air supply module 20 and be blown into the room under the action of the first air supply module 20. The fresh air inlet 4111 is closed to reduce the impact of outdoor air on indoor ambient temperature, etc. When the guide channel 43 is connected, part of the airflow passing through the indoor air inlet 11 can flow through the guide channel 43 to the first air supply module 20 and be blown into the room under the action of the first air supply module 20. The fresh air inlet 4111 is closed to reduce the impact of outdoor air on indoor ambient temperature, etc.

[0062] Specifically, in one embodiment, the fresh air duct 42 has a first air inlet 44 communicating with the indoor air inlet 11, the guide channel 43 has a second air inlet 45 communicating with the indoor air inlet 11, and the exchange door 46 is rotatably connected to the fresh air housing 41 and has a first position, a second position, and a third position; in the first position, the exchange door 46 closes the first air inlet 44, in the second position, the exchange door 46 closes the second air inlet 45, and in the third position, the exchange door 46 closes both the first air inlet 44 and the second air inlet 45. In other words, by utilizing the cooperation of the exchange door 46 with the first air inlet 44 and the second air inlet 45, the selective communication between the fresh air duct 42, the guide channel 43, and the indoor air inlet 11 is satisfied, thereby meeting the user's air supply requirements in different modes and improving user comfort.

[0063] Combined with reference Figures 4 to 7 , Figures 14 to 18In one embodiment, the converter door 46 includes a first door body 461 and a second door body 462 arranged at an angle. When the converter door 46 is rotated in a controlled manner, in the first position, the first door body 461 closes the first air inlet 44; in the second position, the second door body 462 closes the second air inlet 45; and in the third position, the first door body 461 closes the second air inlet 45, and the second door body 462 closes the first air inlet 44. The ends of the first door body 461 and the second door body 462 are connected to a rotating shaft 463, which facilitates the converter door 46 to be connected to a first motor 47 through the rotating shaft 463. Under the drive of the first motor 47, the converter door 46 can switch between the first position, the second position, and the third position, thereby reliably controlling the opening and closing of the first air inlet 44 and the second air inlet 45.

[0064] The angle between the first door 461 and the second door 462 can be any angle, such as a right angle, an obtuse angle, or an acute angle, and can be selected and set according to the arrangement of the first air inlet 44 and the second air inlet 45.

[0065] Specifically, in one embodiment, the first door body 461 and the second door body 462 are an integral structure, which facilitates the simultaneous driving of the first door body 461 and the second door body 462 by a single first motor 47. This satisfies the opening and closing of the first air inlet 44 and the second air inlet 45, reliably ensuring the consistency of the opening and closing of the first air inlet 44 and the second air inlet 45, reducing the possibility of opening the first air inlet 44 and the second air inlet 45 simultaneously, and also reducing the number of parts and lowering costs. The first door body 461 and the second door body 462 are integrally molded parts, or fixed into a whole by means of bonding, welding, coaxial connection, etc. In another embodiment, the first door body 461 and the second door body 462 are separate structures.

[0066] Combined with reference Figure 12 In one embodiment, the converter module 40 further includes a fresh air damper 48 and a second motor 49 connected by a transmission connection. The second motor 49 is externally mounted on the fresh air housing 41, and the fresh air damper 48 is rotatably connected to the fresh air inlet 4111 to open or close the fresh air inlet 4111 under the drive of the second motor 49. The second motor 49 is fixed externally to the fresh air housing 41 via a motor mount. The fresh air housing 41 has a first rotating shaft hole 4112 for assembling the fresh air damper 48. The drive shaft of the second motor 49 passes through the first rotating shaft hole 4112 and connects to the fresh air damper 48. Thus, under the drive of the second motor 49, the fresh air damper 48 rotates within the fresh air inlet 4111 to open or close the fresh air inlet 4111. However, in other embodiments, the second motor 49 can be placed inside the fresh air housing 41, and the fresh air damper 48 can be rotatably connected to the edge of the fresh air inlet 4111, thus performing a flipping motion under the drive of the second motor 49 to open or close the fresh air inlet 4111.

[0067] Furthermore, in one embodiment, when the exchange door 46 is in the first position, the fresh air door 48 closes the fresh air inlet 4111, and both the first air supply module 20 and the second air supply module 30 are in working condition; when the exchange door 46 is in the second position, the fresh air door 48 closes the fresh air inlet 4111, the first air supply module 20 is in working condition, and the second air supply module 30 is in non-working condition; when the exchange door 46 is in the third position, the fresh air door 48 opens the fresh air inlet 4111, the first air supply module 20 is in working condition, and the second air supply module 30 is in non-working condition, or both the first air supply module 20 and the second air supply module 30 are in working condition, to ensure that the airflow delivered to the room can meet the user's needs.

[0068] Reference Figures 10 to 17 In one embodiment, the fresh air housing 41 includes a fresh air front housing 412 and a fresh air rear housing 411. The fresh air rear housing 411 is connected to the fresh air front housing 412 to define the fresh air channel 42 and has the fresh air inlet 4111. The fresh air front housing 412 is connected to the first air supply module 20 to define the guide channel 43 and is rotatably connected to the converter door 46. The fresh air rear housing 411 is provided with a slot 4113, and the fresh air front housing 412 is provided with a buckle 4122 that cooperates with the slot 4113. The fresh air rear housing 411 and the fresh air front housing 412 are fixedly connected by the engagement of the slot 4113 and the buckle 4122. In order to ensure the connection stability of the fresh air rear housing 411 and the fresh air front housing 412, bolts can be added to further fix the two.

[0069] The fresh air front cover 412 can be fixed to the first air supply module 20 by means of connection such as snap-fit, embedding, or bolting, so as to ensure that the first air supply inlet 23 of the first air supply module 20 is connected to the guide channel 43, so that the airflow flowing through the guide channel 43 can be introduced into the first air supply module 20 through the first air supply inlet 23.

[0070] The fresh air front cover 412 has two second rotating shaft holes 4121 through which the two rotating shafts 463 of the exchange door 46 pass. The first motor 47 is fixed outside the fresh air front cover 412. The drive shaft of the first motor 47 extends into one of the second rotating shaft holes 4121 and is fixedly connected to the rotating shaft 463 placed in the second rotating shaft hole 4121.

[0071] Specifically, in one embodiment, the air exchange module 40 further includes a purification component 50, which is placed between the fresh air duct 42 and the guide channel 43 to purify the airflow flowing from the fresh air duct 42 to the guide channel 43. It is understood that the connection between the fresh air front shell 412 and the fresh air rear shell 411 also forms an installation hole for the purification component 50 to pass through, which facilitates the assembly of the purification component 50 with the fresh air shell 41. The purification component 50 includes a filter screen 51 and a filter screen support 52. The filter screen 51 filters the airflow passing through the purification component 50 to ensure the cleanliness of the airflow blown into the room.

[0072] In addition, the back panel assembly 15 has a through hole 16 for the purification component 50 to pass through. The through hole 16 is aligned with the mounting hole, which makes it convenient for the purification component 50 to pass through the through hole 16 and the mounting hole in sequence and be inserted into the converter module 40. This causes the filter support 52 to be locked in the through hole 16, and the filter 51 is located between the fresh air duct 42 and the guide duct 43. This helps to improve the efficiency of the purification component 50 in disassembly and assembly, and ensures the purification effect of the purification component 50 on the airflow.

[0073] Generally speaking, a heat exchanger assembly 60 is usually installed in the indoor unit of a floor-standing air conditioner. The heat exchanger assembly 60 is located near the indoor air inlet 11 and is used to exchange heat with the airflow flowing through it to form a heat exchange airflow, so that the indoor unit has cooling and heating functions.

[0074] Furthermore, under the design of the above features, the indoor unit has a cooling / heating air delivery mode, an indoor purified air delivery mode, an outdoor fresh air delivery mode, and a mixed air delivery mode.

[0075] like Figure 4 As shown, in the mode of delivering cooling and heating air, the converter door 46 is in the first position, that is, the first air inlet 44 is closed and the second air inlet 45 is opened. At this time, the fresh air door 48 closes the fresh air inlet 4111, the converter module 40 is connected to the indoor air inlet 11 through the guide channel 43, and the first air supply module 20 and the second air supply module 30 are both in working state.

[0076] When the indoor unit is turned on for cooling or heating, indoor air enters the outer casing 10 through the indoor air inlet 11. After being cooled or heated by the heat exchanger assembly 60, some of the airflow can be delivered to the room through the second air supply module 30. At the same time, some of the airflow enters the guide channel 43 through the second air inlet 45, enters the first air supply module 20 through the first air supply inlet 23, and is delivered to the room under the action of the first air supply module 20, thus completing the temperature regulation of the indoor air.

[0077] like Figure 5As shown, in the mode of delivering indoor purified air, the exchange door 46 is in the second position, that is, the second air inlet 45 is closed and the first air inlet 44 is opened. At this time, the fresh air door 48 closes the fresh air inlet 4111, the exchange module 40 is connected to the indoor air inlet 11 through the fresh air channel 42, and the first air supply module 20 is in working state and the second air supply module 30 is in non-working state.

[0078] When the indoor unit's cooling and heating functions are turned off, indoor air enters the outer casing 10 through the indoor air inlet 11. After passing through the heat exchanger assembly 60, the airflow enters the fresh air duct 42 through the first air inlet 44, is purified by the purification assembly 50, and enters the guide duct 43. Then, it enters the first air supply module 20 through the first air supply inlet 23 and is delivered to the room under the action of the first air supply module 20, thus completing the delivery of indoor purified air.

[0079] like Figure 6 As shown, in the mode of supplying outdoor fresh air, the converter door 46 is in the third position, that is, the first air inlet 44 and the second air inlet 45 are closed. At this time, the fresh air door 48 opens the fresh air inlet 4111, the converter module 40 is connected to the outdoor air inlet 12 through the fresh air channel 42, and the first air supply module 20 is in working state, while the second air supply module 30 is in non-working state.

[0080] When the indoor unit's cooling and heating functions are turned off, outdoor air enters the fresh air duct 42 through the outdoor air inlet 12, is purified by the purification component 50, and enters the guide duct 43. Then, it enters the first air supply module 20 through the first air supply inlet 23 and is delivered to the room under the action of the first air supply module 20, thus completing the delivery of outdoor purified air.

[0081] like Figure 7 As shown, in the mixed air delivery mode, the converter door 46 is in the third position, that is, the first air inlet 44 and the second air inlet 45 are closed. At this time, the fresh air door 48 opens the fresh air inlet 4111, the converter module 40 is connected to the outdoor air inlet 12 through the fresh air channel 42, and the first air supply module 20 and the second air supply module 30 are both in working state.

[0082] When the indoor unit is turned on for cooling or heating, indoor air enters the outer casing 10 through the indoor air inlet 11. After being cooled or heated by the heat exchanger assembly 60, the airflow can be delivered to the room through the second air supply module 30. Outdoor air enters the fresh air duct 42 through the outdoor air inlet 12, is purified by the purification assembly 50, and enters the guide duct 43. Then, it enters the first air supply module 20 through the first air supply inlet 23 and is delivered to the room under the action of the first air supply module 20, thus completing the delivery of mixed air.

[0083] Optionally, in one embodiment, the first air supply module 20 has a first air supply outlet 24, the second air supply module 30 has a second air supply outlet 34, and the housing 10 has a first main air outlet 13 connected to the first air supply outlet 24 and a second main air outlet 13 connected to the second air supply outlet 34. The arrangement of the first main air outlet 13 and the second main air outlet 13 helps to increase the air supply area, thereby allowing the air volume and the feeling of no wind to be fully and finely adjusted, thus optimizing comfort.

[0084] The second main air outlet 13 and the first main air outlet 13 can be arranged at intervals, and the second main air outlet 13 is located above or below the first main air outlet 13. Alternatively, the second main air outlet 13 and the first main air outlet 13 can be arranged side by side. In other words, the first main air outlet 13 and the second main air outlet 13 can be arranged at any position on the front panel assembly 14 to further expand the air supply area, improve the feeling of no wind, and at the same time facilitate the efficiency of filling the room with the airflow flowing out of the first main air outlet 13 and the second main air outlet 13.

[0085] Reference Figures 4 to 7 In one embodiment, the floor-standing air conditioner indoor unit further includes an air outlet frame 70, which is connected to the first air outlet 24 and the second air outlet 34 respectively. The first main air outlet 13 and the second main air outlet 13 are configured as the same main air outlet 13 and are connected to the air outlet frame 70. In the cooling and heating air delivery mode, the airflow delivered by the first air delivery module 20 and the second air delivery module 30 are combined through the air outlet frame 70 and then delivered to the room. In the indoor purification air delivery mode or the outdoor fresh air delivery mode, the airflow delivered by the first air delivery module 20 is delivered to the room through the air outlet frame 70. In the mixed air delivery mode, the airflow delivered by the first air delivery module 20 and the second air delivery module 30 are mixed in the air outlet frame 70 and then delivered to the room. In this mode, the setting of the air outlet frame 70 helps to avoid extreme temperatures of the airflow delivered to the room, i.e., excessively hot or cold temperatures, which helps to improve the user's comfort.

[0086] Combined with reference Figure 9In one embodiment, the first air supply module 20 includes a first air supply housing 21 and a centrifugal fan 25. The first air supply housing 21 has a centrifugal duct 22 and a first air supply inlet 23 and a first air supply outlet 24 communicating with the centrifugal duct 22. The centrifugal fan 25 is built into the centrifugal duct 22, with its air inlet side facing the first air supply inlet 23. The first air supply housing 21 includes a first air supply front shell 211 and a first air supply rear shell 212. A first air supply rear shell 212 is connected to form a centrifugal air duct 22 and a first air supply outlet 24 connected to the centrifugal air duct 22. The first air supply rear shell 212 has a first air supply inlet 23 and is connected to the fresh air front shell 412 of the converter module 40. The centrifugal fan 25 is connected to the first air supply front shell 211, and its air inlet is directly facing the first air supply inlet 23, ensuring that the airflow flowing in through the first air supply inlet 23 can flow in the centrifugal air duct 22 under the action of the centrifugal fan 25 and be delivered to the room through the first air supply outlet 24.

[0087] Optionally, in one embodiment, the second air supply module 30 includes a second air supply housing 31 and a cross-flow fan 35. The second air supply housing 31 is provided with a cross-flow duct 32 and has a second air supply inlet 33 and a second air supply outlet 34 that connects to the cross-flow duct 32. The cross-flow fan 35 is built into the cross-flow duct 32 and its air inlet side faces the indoor air inlet 11. This arrangement facilitates the airflow flowing in through the indoor air inlet 11 to quickly flow to the second air supply inlet 33 of the second air supply module 30, and under the action of the cross-flow fan 35, flows through the cross-flow duct 32 and flows out of the second air supply module 30 through the second air supply outlet 34.

[0088] Optionally, in one embodiment, the floor-standing air conditioner indoor unit further includes a heat exchanger assembly 60. The heat exchanger assembly 60 and the second air supply module 30 are located above the first air supply module 20 and the air exchange module 40. In this case, the air outlet frame 70 can be located above the first air supply module 20 and on the side of the second air supply module 30. With this arrangement, in the cooling mode, the cold air will flow downward and quickly fill the room, while in the heating mode, the hot air delivered by the first air supply module 20 can flow upward quickly and flow into the room through the air outlet frame 70.
