Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to a method for controlling the airflow of a cabinet air conditioner and the cabinet air conditioner itself. Background Technology

[0002] The fresh air function of existing air conditioners mainly draws fresh outdoor air into the room to improve indoor air quality. When poor indoor air quality is detected, the fresh air function is turned on, and the fresh air blown out directly into the room to purify the air. It cannot adjust the fresh air outlet position by detecting the air quality at different locations in the room to achieve different modes of fresh air supply. Summary of the Invention

[0003] To overcome the problem that air conditioners in related technologies cannot adjust the fresh air outlet position by detecting the air quality at different locations in the room, this invention proposes an air outlet control method and a cabinet air conditioner. By detecting the indoor air quality and the stratification of the indoor air quality, and controlling the air intake and exhaust at different air outlets, different fresh air outlet modes are achieved, thereby improving the speed of air conditioning in purifying indoor air quality and increasing the air volume of the air conditioner.

[0004] The first aspect of this invention proposes an air outlet control method for a cabinet air conditioner. The cabinet air conditioner has an upper air outlet at the top and a lower air outlet at the bottom. The air outlet mode of the air conditioner includes a single upper air outlet mode where the upper air outlet outlet alone outlets the air, a single lower air outlet mode where the lower air outlet outlet outlet alone outlets the air, and a simultaneous upper and lower air outlet mode where the upper and lower air outlet outlets outlet simultaneously outlets the air. The air conditioner also has a fresh air inlet and an indoor air outlet. The fresh air inlet is connected to the outdoor environment and is controlled to open when the air conditioner is in fresh air mode. The indoor air outlet is connected to the indoor environment and can be controlled to open and close. The fresh air mode of the air conditioner includes an independent fresh air mode when the indoor air outlet outlet is closed and a mixed fresh air mode when the indoor air outlet outlet is open.

[0005] Air supply control methods include, when the air conditioner is operating in fresh air mode:

[0006] Acquire indoor air quality data, determine whether the indoor air quality data meets the preset air quality indicators, and determine whether the air conditioner should operate in independent fresh air mode or mixed fresh air mode based on the judgment result;

[0007] The system acquires air quality data from the top and bottom areas of the air conditioner, and controls the airflow mode of the air conditioner based on the determined fresh air mode using the air quality data from the top and bottom areas.

[0008] In the above technical solutions, determining whether the air conditioner operates in independent fresh air mode or mixed fresh air mode based on the judgment result includes:

[0009] If the indoor air quality data does not meet the preset air quality index, the air conditioner will be controlled to operate in independent fresh air mode;

[0010] If the indoor air quality data meets the preset air quality index, the air conditioner will be controlled to operate in mixed fresh air mode.

[0011] In the above technical solutions, the air outlet methods of the air conditioner include a dual air outlet method in which air is discharged from both the upper and lower air outlets at the same time, and a single air outlet method in which air is discharged from the upper air outlet and air is discharged from the lower air outlet separately.

[0012] The fresh air mode is determined by combining air quality data from the top and bottom areas of the air conditioner to control the airflow pattern of the air conditioner, including:

[0013] Based on the determined fresh air mode, compare whether the difference between the air quality data C on the top area of ​​the air conditioner and the air quality data C below the bottom area of ​​the air conditioner is greater than or equal to the preset difference C2, and control the air conditioner to output air in a dual-air output mode or a single-air output mode based on the comparison result.

[0014] The higher the indoor air quality data, the worse the indoor air quality.

[0015] In the above technical solution, based on the determined fresh air mode, the difference between the air quality data C above the top area of ​​the air conditioner and the air quality data C below the bottom area of ​​the air conditioner is compared to whether it is greater than or equal to the preset difference C2, and the air conditioner is controlled to output air in a dual-air-out mode or a single-air-out mode based on the comparison result, including:

[0016] If the absolute value of the difference between C_upper and C_lower is less than the preset difference C2, the air conditioner will then discharge air in a simultaneous upper and lower airflow mode.

[0017] If the absolute value of the difference between C_upper and C_lower is greater than or equal to the preset difference C2, then the relationship between C_upper and C_lower is determined, and the air conditioner is controlled to either output air from the upper vent or the lower vent based on the relationship between C_upper and C_lower.

[0018] In the above technical solutions, the single air outlet method includes the first single air outlet method with air intake at the leeward outlet and air outlet at the upwind outlet, and the second single air outlet method with the leeward outlet closed and air outlet at the upwind outlet.

[0020] Based on the size relationship between C (upper) and C (lower), the air conditioner can be controlled to output air either through the upper vent or the lower vent, including:

[0021] Based on the size relationship between C on top and C below and the specific fresh air mode of the air conditioner, the air conditioner is controlled to output air in either the first single-top air outlet mode, the second single-top air outlet mode, the first single-bottom air outlet mode, or the second single-bottom air outlet mode.

[0022] In the above technical solution, controlling the air conditioner to output air in either the first single-upper air outlet mode, the second single-upper air outlet mode, the first single-lower air outlet mode, or the second single-lower air outlet mode, based on the size relationship between C on top and C on bottom and the specific fresh air mode of the air conditioner, includes:

[0023] In the hybrid fresh air mode:

[0024] If Cup > Cdown and the absolute value of the difference between the two is greater than or equal to the preset difference C2, then the air conditioner will discharge air in the first single-up air outlet mode.

[0025] If Cupper < Clower and the absolute value of the difference between the two is greater than or equal to the preset difference C2, then the air conditioner will output air in the first single-downward air outlet mode.

[0026] In the above technical solution, controlling the air conditioner to output air in either the first single-upper air outlet mode, the second single-upper air outlet mode, the first single-lower air outlet mode, or the second single-lower air outlet mode, based on the size relationship between C on top and C on bottom and the specific fresh air mode of the air conditioner, includes:

[0027] In independent fresh air mode:

[0028] If Cup > Cdown and the absolute value of the difference between the two is greater than or equal to the preset difference C2, then the air conditioner will output air in the second single-up air outlet mode.

[0029] If Cupper < Clower and the absolute value of the difference between the two is greater than or equal to the preset difference C2, then the air conditioner will output air in the second single-down air outlet mode.

[0030] The second aspect of this invention provides a cabinet-type air conditioner. The cabinet-type air conditioner has an upper air vent at the top and a lower air vent at the bottom. The air outlet of the air conditioner includes a single upper air outlet, a single lower air outlet, and a simultaneous upper and lower air outlet. The air conditioner also has a fresh air vent and an indoor air vent. The fresh air vent is connected to the outdoor environment and is controlled to open when the air conditioner is in fresh air mode. The indoor air vent is connected to the indoor environment and can be controlled to open and close. The fresh air mode of the air conditioner includes an independent fresh air mode when the indoor air vent is closed and a mixed fresh air mode when the indoor air vent is open.

[0031] When the air conditioner is running in fresh air mode, the air outlet control method provided in the first aspect of the present invention is used.

[0032] In the above technical solution, the air conditioner includes:

[0033] The casing has an upper air vent at the top and a lower air vent at the bottom.

[0034] The air duct component is located inside the housing and defines a channel between the air duct component and the housing. The top of the air duct component is provided with an upper air duct opening that connects to the upper air vent, and the bottom is provided with a lower air duct opening that connects to the lower air vent.

[0035] The flow path control mechanism is used to control the air duct components to form different air supply paths. The air supply paths of the air duct components include a single downward air supply path with air entering from the fuselage housing channel and exiting from the lower air outlet, a single upward air supply path with air entering from the fuselage housing channel and exiting from the upper air outlet, and a dual air supply path with air entering from the fuselage housing channel and exiting from both the upper and lower air outlets simultaneously.

[0036] The fresh air module has a fresh air inlet. The air inlet's intake end is used to connect to the outdoor environment, and the exhaust end is connected to the casing channel. The fresh air module can introduce outdoor fresh air into the casing channel when the air duct component delivers air through different air delivery paths, so that the air conditioner can form different air outlet patterns when operating in fresh air mode.

[0037] The unit is also equipped with an indoor air vent that connects to the main body casing. The indoor air vent is controlled to open when the air conditioner is running in mixed fresh air mode and to close when the air conditioner is running in independent fresh air mode.

[0038] In the above technical solution, the indoor air vent includes an upper air inlet located at the top of the casing and / or a lower air inlet located at the bottom of the casing.

[0039] In the above technical solution, the air duct component has an upper air supply duct, an upper fan duct, an intermediate air duct, a lower fan duct, and a lower air supply duct arranged sequentially and connected to each other. The upper part of the upper air supply duct is connected to the upper air outlet, and the lower part of the lower air supply duct is connected to the lower air outlet.

[0040] The flow path control mechanism includes an upper flow path control mechanism and a lower flow path control mechanism installed on the air duct component;

[0041] The upstream flow control mechanism can connect the upstream fan duct and the upstream air supply duct while simultaneously blocking the connection between the upstream fan duct and the intermediate air duct. The upstream flow control mechanism can also block the upstream fan duct and the upstream air supply duct while simultaneously connecting the upstream fan duct and the intermediate air duct.

[0042] The downstream flow control mechanism can connect the downstream fan duct and the downstream air supply duct while simultaneously blocking the connection between the downstream fan duct and the intermediate air duct. The downstream flow control mechanism can also block the downstream fan duct and the downstream air supply duct while simultaneously connecting the downstream fan duct and the intermediate air duct.

[0043] In the above technical solution, the upper flow path control mechanism can also connect the upper fan duct and the upper air supply duct at the same time, and the upper flow path control mechanism can also block the connection between the upper air supply duct and the middle air duct at the same time.

[0044] The downstream flow control mechanism can also connect the downstream fan duct and the downstream air supply duct while simultaneously connecting the downstream air supply duct and the intermediate air supply duct. Furthermore, the downstream flow control mechanism can also block the connection between the downstream air supply duct and the intermediate air supply duct while simultaneously blocking the connection between the downstream fan duct and the downstream air supply duct.

[0045] In the above technical solution, the upwind and downwind vents can be controlled to open or close.

[0046] The upper air supply duct has an upper return air inlet on its duct wall that connects the fuselage casing and the upper air duct, and the lower air supply duct has a lower return air inlet on its duct wall that connects the fuselage casing and the lower air duct.

[0047] The upper flow path control mechanism can close the upper return air outlet while connecting the upper air supply duct and the upper fan duct, and open the upper return air outlet when blocking the connection between the upper air supply duct and the upper fan duct;

[0048] The downflow control mechanism can close the downflow return air outlet while connecting the downflow air duct and the downflow fan duct, and open the downflow return air outlet when blocking the connection between the downflow air duct and the downflow fan duct.

[0049] In the above technical solution, the cabinet air conditioner also includes an upper fan installed in the upper fan duct and a lower fan installed in the lower fan duct.

[0050] The upper air supply duct has an upper air supply duct A side close to the upper fan side and an upper air supply duct B side close to the upper air outlet side. The upper air supply duct includes a first upper air supply duct and a second upper air supply duct that are separated on the upper air supply duct A side and connected on the upper air supply duct B side.

[0051] The downflow duct has a downflow duct A side near the downflow fan and a downflow duct B side near the downflow outlet. The downflow duct includes a first downflow duct and a second downflow duct that are separated on the downflow duct A side and connected on the downflow duct B side.

[0052] The upper flow path control mechanism includes an upper baffle mechanism rotatably disposed at the connection position between the upper fan duct and the first upper supply air duct, and an upper volute mechanism capable of circumferentially sliding around a preset rotation axis of the upper fan. The upper baffle mechanism has a first upper rotation position and a second upper rotation position when rotating, and the upper volute mechanism has a first upper sliding position and a second upper sliding position when sliding. When the upper baffle mechanism is in the first upper rotation position, the upper return air inlet is opened while blocking the connection between the upper fan duct and the first upper supply air duct. When the upper baffle mechanism is in the second upper rotation position, the upper return air inlet is closed while connecting the upper fan duct and the first upper supply air duct. When the upper volute mechanism is in the first upper sliding position, the upper fan duct maintains connection with the intermediate air duct while blocking the connection between the upper fan duct and the second upper supply air duct. When the upper volute mechanism is in the second upper sliding position, the upper fan duct connects with the second upper supply air duct while blocking the connection between the upper fan duct and the intermediate air duct.

[0053] The downstream flow control mechanism includes a lower baffle mechanism rotatably positioned at the connection point between the downstream fan duct and the first downstream air supply duct, and a lower volute mechanism capable of circumferentially sliding around a preset rotation axis of the downstream fan. The lower baffle mechanism has a first lower rotation position and a second lower rotation position when rotating, and the lower volute mechanism has a first lower sliding position and a second lower sliding position when sliding. When the lower baffle mechanism is in the first lower rotation position, the downstream return air inlet is opened while simultaneously blocking the connection between the downstream fan duct and the first downstream air supply duct. When the lower baffle mechanism is in the second lower rotation position, the downstream return air inlet is closed while simultaneously connecting the downstream fan duct and the first downstream air supply duct. When the lower volute mechanism is in the first lower sliding position, the downstream fan duct remains connected to the intermediate air supply duct while simultaneously blocking the connection between the downstream fan duct and the second downstream air supply duct. When the lower volute mechanism is in the second sliding position, the downstream fan duct connects to the second downstream air supply duct while simultaneously blocking the connection between the downstream fan duct and the intermediate air supply duct.

[0054] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0055] This invention proposes a method for controlling the airflow of a cabinet air conditioner. By detecting indoor air quality and its stratification, and controlling the air intake and exhaust at different vents, it achieves different fresh air output modes, thereby increasing the speed at which the air conditioner purifies indoor air and simultaneously increasing the airflow volume.

[0083] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0084] Current air conditioners cannot adjust the fresh air outlet position by detecting the air quality at different locations in the room. This invention proposes a method for controlling the air outlet of a cabinet-type air conditioner and the cabinet-type air conditioner itself. By detecting indoor air quality and the stratification of indoor air quality, it controls the intake and exhaust of different air vents to achieve different fresh air outlet modes, thereby improving the speed of indoor air purification and increasing the air volume output of the air conditioner.

[0085] The following is in conjunction with the appendix Figure 1 -Attached Figure 16 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0086] Example

[0087] like Figure 1 and Figure 2 As shown, the first aspect of the present invention proposes an air outlet control method for a cabinet air conditioner. The cabinet air conditioner has an upper air outlet at the top and a lower air outlet at the bottom. The air outlet mode of the air conditioner includes a single upper air outlet mode where the upper air outlet outlet alone outlets the air, a single lower air outlet mode where the lower air outlet outlet outlet alone outlets the air, and a simultaneous upper and lower air outlet mode where the upper and lower air outlet outlets outlet simultaneously outlets the air. The air conditioner also has a fresh air inlet and an indoor air outlet. The fresh air inlet is connected to the outdoor environment and is controlled to open when the air conditioner is in fresh air mode. The indoor air outlet is connected to the indoor environment and can be controlled to open and close. The fresh air mode of the air conditioner includes an independent fresh air mode when the indoor air outlet outlet is closed and a mixed fresh air mode when the indoor air outlet outlet is open.

[0088] Air supply control methods include, when the air conditioner is operating in fresh air mode:

[0089] Acquire indoor air quality data, determine whether the indoor air quality data meets the preset air quality indicators, and determine whether the air conditioner should operate in independent fresh air mode or mixed fresh air mode based on the judgment result;

[0090] The system acquires air quality data for the top and bottom areas of the air conditioner, and controls the airflow pattern of the air conditioner based on the air quality data for the top and bottom areas and the determined fresh air mode.

[0091] In this embodiment of the invention, by acquiring indoor air quality and the stratification of indoor air quality, and by controlling the air intake and exhaust of different air vents, different fresh air exhaust modes are achieved, thereby improving the speed of air conditioning in purifying indoor air quality and increasing the air volume of the air conditioner.

[0092] Specifically, in this embodiment of the invention, indoor air quality data is acquired and compared with preset air quality indicators to determine whether the indoor air quality is severely polluted. Air quality data of the top area and the bottom area of ​​the air conditioner are acquired to determine whether the indoor air quality is severely stratified under the current air quality conditions. In this way, different fresh air modes and different air outlet methods are selected to adjust the indoor air in a targeted manner.

[0093] It should be noted that when the air conditioner in this embodiment of the invention acquires indoor air quality data, it can acquire air quality data from any location indoors, and the acquired air quality data may include multiple air quality parameters. This embodiment of the invention does not limit the specific acquisition location or the specific air quality parameters.

[0094] In some implementations, the air conditioner is determined to operate in independent fresh air mode or mixed fresh air mode based on the judgment result, including:

[0095] If the indoor air quality data does not meet the preset air quality index, the air conditioner will be controlled to operate in independent fresh air mode;

[0096] If the indoor air quality data meets the preset air quality index, the air conditioner will be controlled to operate in mixed fresh air mode.

[0097] Specific;

[0098] When the sensor detects that the indoor air quality data does not meet the preset air quality index, the indoor air quality is poor. In order to quickly purify the indoor air, the air conditioner enters the independent fresh air mode and closes the indoor air vents to prevent the poor indoor environment from being drawn into the air conditioner.

[0099] When the sensor detects that the indoor air quality data meets the preset air quality index, the indoor air quality is not very bad. At this time, the air conditioner can enter the mixed fresh air mode, and the indoor air vents open to introduce indoor air into the air conditioner, thereby purifying the indoor air quality while increasing the air volume of the air conditioner.

[0100] In some implementations, the air outlet of the air conditioner includes a dual air outlet mode in which air is discharged from both the upper and lower air outlets simultaneously, and a single air outlet mode in which air is discharged from both the upper and lower air outlets separately.

[0101] The fresh air mode is determined by combining air quality data from the top and bottom areas of the air conditioner to control the airflow pattern of the air conditioner, including:

[0102] Based on the determined fresh air mode, compare whether the difference between the air quality data C on the top area of ​​the air conditioner and the air quality data C below the bottom area of ​​the air conditioner is greater than or equal to the preset difference C2, and control the air conditioner to output air in a dual-air output mode or a single-air output mode based on the comparison result.

[0103] The higher the indoor air quality data, the worse the indoor air quality.

[0104] In other words, when the air conditioner in this embodiment of the invention is running in fresh air mode, if the indoor air quality stratification is not severe, the air conditioner can be controlled to simultaneously supply air from the upper and lower vents, thereby achieving a wraparound fresh air supply and uniformly purifying all the indoor air. If the indoor air quality stratification is severe, fresh air can be supplied to specific areas with poor air quality, quickly purifying those areas.

[0105] In some implementations, based on the determined fresh air mode, the difference between the air quality data C above the top area of ​​the air conditioner and the air quality data C below the bottom area of ​​the air conditioner is compared to see if it is greater than or equal to a preset difference C2, and the air conditioner is controlled to output air in a dual-air-outlet mode or a single-air-outlet mode based on the comparison result, including:

[0106] If the absolute value of the difference between C_upper and C_lower is less than the preset difference C2, the air conditioner will then discharge air in a simultaneous upper and lower airflow mode.

[0107] If the absolute value of the difference between C_upper and C_lower is greater than or equal to the preset difference C2, then the relationship between C_upper and C_lower is determined, and the air conditioner is controlled to either output air from the upper vent alone or from the lower vent alone based on the relationship between C_upper and C_lower.

[0108] Specifically, in some implementations, the upwind outlet single air outlet method includes a first single upwind outlet method where air enters from the downwind outlet and exits from the upwind outlet, and a second single upwind outlet method where the downwind outlet is closed and air exits from the upwind outlet;

[0109] The downwind outlet separate air outlet method includes the first type of single downwind outlet air outlet method, which is air inlet at the upwind outlet and air outlet at the downwind outlet, and the second type of single downwind outlet air outlet method, which is air outlet closed at the upwind outlet and air outlet at the downwind outlet.

[0110] The control of air conditioning based on the size relationship between C (upper) and C (lower) involves either allowing air to flow solely from the upper vent or solely from the lower vent, including:

[0111] Based on the size relationship between C on top and C below and the specific fresh air mode of the air conditioner, the air conditioner is controlled to output air in either the first single-top air outlet mode, the second single-top air outlet mode, the first single-bottom air outlet mode, or the second single-bottom air outlet mode.

[0112] When there is uneven air quality in the room, it is necessary to consider the specific fresh air mode of the air conditioner. Specifically, it is necessary to consider whether the air conditioner is running in independent fresh air mode or mixed fresh air mode. Since independent fresh air mode cannot introduce indoor air, while mixed fresh air mode can, different air outlet methods can be selected according to the specific fresh air mode.

[0113] Specifically, in some implementations, based on the size relationship between C on top and C below and the specific fresh air mode of the air conditioner, the air conditioner is controlled to output air in either a first single-top air outlet mode, a second single-top air outlet mode, a first single-bottom air outlet mode, or a second single-bottom air outlet mode, including:

[0114] In the hybrid fresh air mode:

[0115] If Cup > Cdown and the absolute value of the difference between the two is greater than or equal to the preset difference C2, then the air conditioner will discharge air in the first single-up air outlet mode.

[0116] If Cupper < Clower and the absolute value of the difference between the two is greater than or equal to the preset difference C2, then the air conditioner will output air in the first single-downward air outlet mode.

[0117] In the mixed fresh air mode, since indoor air can enter the air conditioner, when one of the air outlets is discharging air, the other can be used as an air inlet by the flow path control mechanism, thereby increasing the air intake and delivery volume of the air conditioner.

[0118] Specifically, in some implementations, based on the size relationship between C on top and C below and the specific fresh air mode of the air conditioner, the air conditioner is controlled to output air in either a first single-top air outlet mode, a second single-top air outlet mode, a first single-bottom air outlet mode, or a second single-bottom air outlet mode, including:

[0119] In independent fresh air mode:

[0120] If Cup > Cdown and the absolute value of the difference between the two is greater than or equal to the preset difference C2, then the air conditioner will output air in the second single-up air outlet mode.

[0121] If Cupper < Clower and the absolute value of the difference between the two is greater than or equal to the preset difference C2, then the air conditioner will output air in the second single-down air outlet mode.

[0122] In independent fresh air mode, since indoor air cannot enter the air conditioner, one of the upper and lower air vents is closed while air is being discharged, thus preventing indoor air from entering the air conditioner and affecting its fresh air purification effect.

[0123] To better understand the air outlet control principle of the air conditioner in this embodiment of the invention, the following is a detailed explanation. Figure 2Please provide a detailed explanation:

[0124] In independent fresh air mode:

[0125] When the difference between the upper air quality sensor and the lower air quality sensor (which detects a positive value) is greater than or equal to the set value C2, the indoor air quality is severely stratified, with the upper air quality being worse than the lower air quality. To quickly purify the upper air, the lower vent at the bottom of the air conditioner is closed, while the upper vent at the top is connected to the fan. Under the combined action of the fan system and the fresh air system, the fresh air system filters the outdoor air and introduces it into the air conditioner's casing. The fresh air is then blown out from the upper vent by the fan system, achieving targeted fresh air supply at the top and quickly purifying the upper air.

[0126] When the difference between the upper air quality sensor and the lower air quality sensor (which detects a negative value) is greater than or equal to the set value C2, the indoor air quality is severely stratified, with the lower air quality being worse than the upper air quality. To quickly purify the upper air, the upper vent is closed, and the lower vent is connected to the fan. Under the combined action of the fan system and the fresh air system, the fresh air system filters the outdoor air and introduces it into the air conditioner's casing. The fresh air is then blown out from the lower vent by the fan system, achieving targeted fresh air supply to the lower level and quickly purifying the lower air.

[0127] When the absolute value of the difference between the upper air quality sensor detecting the indoor upper air quality C_upper and the lower air quality sensor detecting the indoor lower air quality C_lower is less than the set value C2, the indoor air quality distribution is uniform. The upper and lower air vents are open, with the upper vent connected to the upper fan system and the lower vent connected to the lower fan system. Under the combined action of the fan system and the fresh air system, the fresh air system filters the outdoor air and introduces it into the air conditioner housing duct. Under the action of the fan system, the air is blown out from the upper and lower air vents respectively, realizing the indoor air surround fresh air supply and uniformly purifying all indoor air.

[0128] In the hybrid fresh air mode:

[0129] If the absolute value of the difference between C_upper and C_lower is less than the preset difference C2, it indicates that the indoor air quality is evenly distributed vertically and there is no stratification. At this time, the upper air vent of the air conditioner can be connected to the upper fan system, and the lower air vent can be connected to the lower fan system. Outdoor air enters from the fresh air inlet, is filtered by the fresh air system, and is blown out from the fresh air outlet into the casing channel. At the same time, indoor air enters the air conditioner from the indoor air vent, mixes with the fresh air in the casing channel, and is blown out simultaneously from the upper air vent at the top and the lower air vent at the bottom of the air conditioner under the action of the fan system, achieving a surround-style purification of indoor air quality and allowing users to experience surround-style cooling and fresh air.

[0130] If the absolute value of the difference between C_upper and C_lower is greater than or equal to the preset difference C2, it indicates that the indoor air is stratified. Since the indoor air quality is not too bad at this time, indoor air can be introduced. Therefore, the airflow control mechanism can control one of the upper or lower air inlets on the top of the air conditioner as the air inlet, thereby increasing the air intake of the air conditioner.

[0131] Specifically:

[0132] Taking the air conditioner in cooling mode as an example, when the absolute value of the difference between the indoor air quality Cupper detected by the upper air quality sensor and the indoor air quality Clower detected by the lower air quality sensor is greater than or equal to the set value C2, it indicates that the indoor air quality is severely stratified. When Cupper > Clower, it indicates that the air quality in the upper part is worse than that in the lower part. At this time, the lower air vent at the bottom of the air conditioner is converted into an air inlet, and the upper air vent is connected to the fan cavity. Outdoor air enters from the fresh air inlet, is filtered by the fresh air system, and is blown out from the fresh air outlet into the casing channel. At the same time, indoor air also enters the casing channel inside the air conditioner from the indoor air vent and the lower air vent (the indoor air vent, including the upper air inlet and the lower air inlet, will be described in detail below). After mixing with the fresh air in the unit casing channel, the air is blown out from the upper vent under the action of the fan system, achieving simultaneous purification of the poor-quality air in the upper part during cooling. This increases the air volume for cooling and makes the air fresher during cooling. When Cupper < Clower, it means that the air quality in the lower part of the room is worse than that in the upper part. At this time, the upper vent becomes an air inlet, and the lower vent connects to the fan cavity. Outdoor air enters from the fresh air inlet, is filtered by the fresh air system, and is blown out from the fresh air outlet into the unit casing channel. Indoor air enters from the indoor air outlet and the upper vent into the unit casing channel. After mixing with the fresh air in the channel, it is blown out from the lower vent under the action of the fan system, thus achieving targeted purification of indoor air quality during cooling.

[0133] Taking the air conditioner in heating mode as an example, when the absolute value of the difference between the indoor air quality Cupper detected by the upper air quality sensor and the indoor air quality Clower detected by the lower air quality sensor is greater than or equal to the set value C2, it indicates that the indoor air quality is severely stratified. When Cupper < Clower, it indicates that the air quality in the lower part of the room is worse than that in the upper part. At this time, the upper air vent on the top of the air conditioner is converted into an air inlet, and the lower air vent is connected to the fan cavity. Outdoor air enters from the fresh air inlet, is filtered by the fresh air system, and is blown out from the fresh air outlet into the casing channel. Indoor air enters from the indoor air vent and the upper air vent, enters the casing channel, mixes with the fresh air in the channel, and then flows into the fan system. The air is blown out from the lower vent, simultaneously purifying the lower, lower-quality air during heating. This increases the airflow volume during heating and makes the air fresher, improving air conditioning comfort. When Cupper > Clower, the air quality in the upper part is worse than that in the lower part. The lower vent at the bottom of the air conditioner becomes an air inlet, and the upper vent connects to the fan cavity. Outdoor air enters through the fresh air inlet, is filtered by the fresh air system, and is blown out through the fresh air outlet into the casing channel. Indoor air enters through the indoor air outlet and the lower vent, mixes with the fresh air in the casing channel, and is then blown out through the upper vent at the top of the air conditioner by the fan system, achieving targeted purification of indoor air quality during heating.

[0134] Further, such as Figures 3-16 As shown, the second aspect of the present invention also provides a cabinet air conditioner. The cabinet air conditioner has an upper air outlet 11 at the top and a lower air outlet 12 at the bottom. The air outlet of the air conditioner includes a single upper air outlet mode where the upper air outlet 11 alone outlets the air, a single lower air outlet mode where the lower air outlet 12 alone outlets the air, and a simultaneous upper and lower air outlet mode where the upper and lower air outlets outlet the air simultaneously. The air conditioner also has a fresh air outlet and an indoor air outlet. The fresh air outlet is connected to the outdoor environment and is controlled to open when the air conditioner is in fresh air mode. The indoor air outlet is connected to the indoor environment and can be controlled to open and close. The fresh air mode of the air conditioner includes an independent fresh air mode when the indoor air outlet is closed and a mixed fresh air mode when the indoor air outlet is open.

[0135] When the air conditioner is running in fresh air mode, the air outlet control method provided in the first aspect of the embodiment is used.

[0136] In some embodiments, the above-mentioned cabinet air conditioner includes:

[0137] The housing 1 has an upper air vent 11 at the top and a lower air vent 12 at the bottom.

[0138] Air duct component 2 is located inside the housing 1 and defines the housing channel 3 between the housing 1 and the housing 1. The top of the air duct component 2 is provided with an upper air duct opening 21 that connects to the upper air vent 11, and the bottom is provided with a lower air duct opening 22 that connects to the lower air vent 12.

[0139] The flow path control mechanism is used to control the air duct component 2 to form different air supply paths. The air supply paths of the air duct component 2 include a single downward air supply path with air entering from the fuselage housing channel 3 and exiting from the lower air outlet 22, a single upward air supply path with air entering from the fuselage housing channel 3 and exiting from the upper air outlet 21, and a dual air supply path with air entering from the fuselage housing channel 3 and exiting from both the upper air outlet 21 and the lower air outlet 22.

[0140] Fresh air module 4 has a fresh air inlet, wherein the air inlet is used to connect to the outdoor environment and the exhaust end is connected to the body housing channel 3. The fresh air module 4 can introduce outdoor fresh air into the body housing channel 3 when the air duct component 2 delivers air through different air delivery paths.

[0141] The casing 1 is also provided with an indoor air vent that connects to the casing channel 3. The indoor air vent is controlled to open when the air conditioner is running in mixed fresh air mode and controlled to close when the air conditioner is running in independent fresh air mode.

[0142] The cabinet air conditioner provided in this embodiment of the invention enables the air duct component to form different air supply paths by setting a flow control mechanism in the air duct component. At the same time, a fresh air module is set and connected to the air conditioner's body casing channel. In this way, when the air conditioner is running in fresh air mode, fresh air can enter the air duct component 2 through the body casing channel 3 and switch with the air supply path of the air duct component to achieve fresh air supply effect at different locations. Meanwhile, the indoor air vents on the air conditioner casing 1 can be controlled to open or close. When the indoor air vents are closed, the fresh air module can act as the air inlet of the air conditioner to provide air volume to the air conditioner, thereby realizing an independent fresh air supply mode. When the air inlet is opened, the fresh air module can also provide air volume to the entire air conditioner, thereby realizing a large air volume mixed fresh air supply mode.

[0143] In some implementations, such as Figure 9 and Figure 10 As shown, the indoor air vents include an upper air inlet 13 located at the top of the housing 1 and / or a lower air inlet 14 located at the bottom of the housing 1.

[0144] Preferably, air inlets are provided at both the top and bottom of the casing 1, which can increase the air intake of the entire air conditioner.

[0145] In some embodiments, the opening and closing of the upper air inlet 13 and the lower air inlet 14 are controlled by baffles, i.e. Figures 13-16 As shown, an upper baffle plate 1i is rotatably installed at the upper air inlet 13 to control the opening and closing of the upper air inlet 13, and a lower baffle plate 1h is rotatably installed at the lower air inlet 14 to control the opening and closing of the lower air inlet 14.

[0146] Of course, in some alternative implementations, the opening and closing of the upper air inlet 13 and the lower air inlet 14 can also be achieved by other mechanisms, such as setting on / off valves or other on / off components at the positions of the upper air inlet 13 and the lower air inlet 14. In this embodiment, the specific on / off structure of the upper air inlet 13 and the lower air inlet 14 is not limited.

[0147] In some implementations, such as Figure 9 and Figure 10 As shown, the cabinet air conditioner has a front side facing the user when installed, and a rear side opposite the front side;

[0148] The downvent 21 is located at the bottom front of the air conditioner, and the fresh air module 4 is located at the bottom rear of the air conditioner.

[0149] By placing the downvent 21 at the bottom front of the air conditioner, the hot air can fully contact the bottom surface and rise when the air conditioner is in heating mode, thereby improving the heating effect of the air conditioner. By placing the fresh air module 4 at the bottom rear of the air conditioner, it is convenient to connect the air inlet pipe of the fresh air module to the outside, and it is convenient to install the pipeline of the fresh air module 4.

[0150] In some implementations, such as Figures 5-8 As shown, the air duct component 2 has an upper air supply duct 2a, an upper fan air duct 2b, an intermediate air duct 2c, a lower fan air duct 2d, and a lower air supply duct 2e arranged vertically and communicating with each other. The upper part of the upper air supply duct 2a is connected to the upper air duct opening 21, and the lower part of the lower air supply duct 2e is connected to the lower air duct opening 22.

[0151] The flow path control mechanism includes an upper flow path control mechanism and a lower flow path control mechanism installed on the air duct component;

[0152] The upper flow path control mechanism can connect the upper fan duct 2b and the upper air supply duct 2a while blocking the connection between the upper fan duct 2b and the middle air duct 2c. The upper flow path control mechanism can also connect the upper fan duct 2b and the middle air duct 2c while blocking the upper fan duct 2b and the upper air supply duct 2a.

[0153] The downstream flow control mechanism can connect the downstream fan duct 2d and the downstream air supply duct 2e while simultaneously blocking the connection between the downstream fan duct 2d and the intermediate air supply duct 2c. The downstream flow control mechanism can also connect the downstream fan duct 2d and the intermediate air supply duct 2c while simultaneously blocking the downstream fan duct 2d and the downstream air supply duct 2e.

[0154] By setting up upper and lower flow path control mechanisms, the air duct components can achieve air delivery effects with different air delivery paths. Specifically:

[0155] When the air conditioner needs to achieve simultaneous airflow from both the top and bottom, the upper airflow control mechanism can be controlled to connect the upper fan duct 2b to the upper supply air duct 2a while simultaneously blocking the connection between the upper fan duct 2b and the middle air duct 2c. Simultaneously, the lower airflow control mechanism can be controlled to connect the lower fan duct 2d to the lower supply air duct 2e while simultaneously blocking the connection between the lower fan duct and the middle air duct. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are activated simultaneously, as shown in 11- Figure 14 As shown, the air conditioner can simultaneously supply air from both the top and bottom. When fresh air needs to be introduced, the fresh air module 4 can be opened to bring in outside fresh air. It's worth noting that when the air conditioner is simultaneously supplying air from both the top and bottom to introduce outside fresh air, different modes of fresh air supply can be achieved by controlling the opening and closing of the air inlet on the air conditioner casing. Specifically, as... Figure 11 As shown, when an independent fresh air mode is needed, the upper air inlet 13 and lower air inlet 14 on the air conditioner casing can be closed, at which point only the fresh air module 4 receives air. More specifically, as... Figure 14 As shown, when a mixed fresh air mode is required, the upper air inlet 13 and the lower air inlet 14 on the air conditioner casing can be opened. At this time, not only the fresh air module 4 is inlet, but also the air inlet on the air conditioner casing is inlet.

[0156] When the air conditioner needs to achieve a single-upper-ventilation effect, the upper fan duct 2b can be connected to the upper air supply duct 2a while simultaneously blocking the connection between the upper fan duct 2b and the intermediate duct 2c by controlling the upper flow path control mechanism. Then, the upper fan in the upper fan duct can be started alone, achieving a single-upper-ventilation effect. Simultaneously, when fresh air needs to be introduced, the fresh air module 4 can be opened to bring outside fresh air into the room. It is worth noting that when the duct component is introducing outside fresh air in a single-upper-ventilation mode, different modes of fresh air supply can be achieved by controlling the opening and closing of the air inlet on the air conditioner casing. Specifically, when an independent fresh air mode is needed, the air inlet on the air conditioner casing can be closed, at which point only the fresh air module 4 receives air. More specifically, when a mixed fresh air mode is needed, the air inlet on the air conditioner casing can be opened, at which point not only the fresh air module 4 receives air, but also the air inlet on the air conditioner casing receives air.

[0157] When the air conditioner needs to achieve a single-downward air supply effect, the lower fan duct 2d can be connected to the lower air supply duct 2e while simultaneously blocking the connection between the lower fan duct 2d and the intermediate duct 2c by controlling the lower airflow control mechanism. Then, the lower fan in the lower fan duct can be started alone, achieving a single-downward air supply effect. Simultaneously, when fresh air needs to be introduced, the fresh air module 4 can be opened to bring outside fresh air into the room. It is worth noting that when the duct component introduces outside fresh air in a single-downward air supply mode, different modes of fresh air supply can be achieved by controlling the opening and closing of the air inlet on the air conditioner casing. Specifically, when an independent fresh air mode is needed, the air inlet on the air conditioner casing can be closed, at which point only the fresh air module 4 receives air. More specifically, when a mixed fresh air mode is needed, the air inlet on the air conditioner casing can be opened, at which point not only the fresh air module 4 receives air, but also the air inlet on the air conditioner casing receives air.

[0158] As can be seen, when the air conditioner in this embodiment delivers fresh air, the fresh air introduced from the outside can flow to different positions in the room by switching the flow path of the air duct component, thereby achieving a variable fresh air delivery effect. At the same time, when delivering fresh air, an independent fresh air mode or a mixed fresh air mode can be selected. Since the exhaust side of the fresh air module in this embodiment is directly connected to the air intake side of the air duct component's housing channel, when the air conditioner is running in mixed fresh air mode, the outside airflow introduced from the fresh air module 4 and the indoor airflow introduced from the air inlet of the air conditioner can be fully mixed in the housing channel before being uniformly discharged into the room. Thus, in this mode, the air volume of the air conditioner can be increased, and the air delivery effect can be improved.

[0159] In some implementations, such as Figures 5-8 As shown, the upper flow path control mechanism can also connect the upper fan duct 2b and the upper air supply duct 2a to the middle air duct 2c at the same time as connecting the upper fan duct 2b and the upper air supply duct 2a. The upper flow path control mechanism can also block the connection between the upper air supply duct 2a and the middle air duct 2c at the same time as blocking the upper fan duct 2b and the upper air supply duct 2a.

[0160] The downstream flow control mechanism can also connect the downstream fan duct 2d and the downstream air supply duct 2e to the intermediate air supply duct 2c at the same time. The downstream flow control mechanism can also block the connection between the downstream air supply duct 2e and the intermediate air supply duct 2c while blocking the downstream fan duct 2d and the downstream air supply duct 2e.

[0161] The advantages of configuring the upper flow path control mechanism and the lower flow path control mechanism as described above in this embodiment are:

[0162] When the air conditioner needs to achieve a single-top air supply effect, the upper fan duct 2b and the upper air supply duct 2a can be connected by controlling the upper flow path control mechanism. At the same time, while blocking the upper fan duct 2b and the middle duct 2c, the upper air supply duct 2a and the middle duct are connected. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. In this way, the lower fan in the lower fan duct 2d can discharge the intake airflow through the middle duct 2c into the upper air supply duct 2a and finally discharge it from the top, thereby improving the air supply power of the air conditioner when it is in single-top air supply, and thus improving the air supply distance and air supply intensity of the air conditioner in single-top air supply.

[0163] Similarly, when the air conditioner needs to achieve a single downward air supply effect, the downward air supply duct 2e can be connected by controlling the downward flow path control mechanism. At the same time, while blocking the downward air supply duct 2d and the intermediate air supply duct 2c, the downward air supply duct 2e and the intermediate air supply duct 2c are connected. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. In this way, the upper fan in the upper fan duct 2b can discharge the intake airflow through the intermediate air supply duct 2c into the downward air supply duct 2e and finally discharge it from the bottom. This improves the air supply power of the air conditioner when it is supplying air only from the top, thereby increasing the air supply distance and air supply intensity of the air conditioner when it is supplying air only from the top.

[0164] In some implementations, such as Figures 5-8 As shown, the upper air vent 11 and the lower air vent 12 can be controlled to open or close; the upper air supply duct 2a has an upper return air vent 23 on its duct wall that connects the fuselage housing channel 3 and the upper air supply duct 2a, and the lower air supply duct 2e has a lower return air vent 24 on its duct wall that connects the fuselage housing channel 3 and the lower air supply duct 2e.

[0165] The upper flow path control mechanism can close the upper return air outlet 23 while connecting the upper air supply duct 2a and the upper fan duct 2b, and open the upper return air outlet 23 when blocking the connection between the upper air supply duct 2a and the upper fan duct 2b.

[0166] The downflow control mechanism can close the downflow return air outlet 24 while connecting the downflow air duct 2e and the downflow fan duct 2d, and open the downflow return air outlet 24 when blocking the connection between the downflow air duct 2e and the downflow fan duct 2d.

[0167] In this embodiment, by providing return air vents on the walls of both the upper air supply duct 2a and the lower air supply duct 2e, and further modifying the upper and lower flow path control mechanisms, the air volume supplied by the air conditioner when only the upper or lower air outlet is located can be further increased. Specifically:

[0168] like Figure 10 and Figure 14As shown, when the air conditioner needs to achieve a single upward air supply effect, the upper fan duct 2b and the upper supply duct 2a can be connected by controlling the upper flow path control mechanism. At the same time, while blocking the upper fan duct 2b and the middle duct 2c, the upper supply duct 2a and the middle duct 2c are connected, and the upper return air vent 23 is closed accordingly. Then, the lower fan duct 2d and the lower supply duct 2e are disconnected by controlling the lower flow path control mechanism. While blocking the lower supply duct 2e and the middle duct 2c, the lower return air vent 24 is opened. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. In this way, the lower fan in the lower fan duct 2d can draw air from the bottom of the air conditioner into the lower supply duct 2e when it is running. The air entering the lower supply duct 2e passes through the lower return air vent 24 and the body casing channel in sequence and is then drawn into the fan of the duct component, and finally discharged from the top of the air conditioner, thereby increasing the air supply volume of the air conditioner when it is in single upward air supply mode.

[0169] Similarly, such as Figure 12 and Figure 16 As shown, when the air conditioner needs to achieve a single downward air supply effect, the lower fan duct 2d and the lower supply duct 2e can be connected by controlling the lower flow path control mechanism. At the same time, while blocking the lower fan duct 2d and the middle duct 2c, the lower supply duct 2e and the middle duct 2c are connected, and the lower return air vent 24 is closed accordingly. Then, the upper fan duct 2b and the upper supply duct 2a are disconnected by controlling the upper flow path control mechanism. While blocking the upper supply duct 2a and the middle duct 2c, the upper return air vent 23 is opened. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started simultaneously. In this way, the upper fan in the upper fan duct 2b can draw air from the top of the air conditioner into the upper supply duct 2a when it is running. The air entering the upper supply duct 2a passes through the upper return air vent 23 and the body casing channel in sequence and is then drawn into the fan of the duct component and finally discharged from the bottom of the air conditioner, thereby increasing the air supply volume of the air conditioner when it is in single downward air supply mode.

[0170] In some implementations, such as Figures 4-7 As shown, the cabinet air conditioner also includes an upper fan 5 located in the upper fan duct 2b and a lower fan 6 located in the lower fan duct 2d.

[0171] The upper air supply duct 2a has an upper air supply duct A side close to the upper fan 5 and an upper air supply duct B side close to the upper air supply duct opening 21. The upper air supply duct 2a includes a first upper air supply duct 2a1 and a second upper air supply duct 2a2 that are separated on the upper air supply duct A side and connected on the upper air supply duct B side.

[0172] The downflow duct 2e has a downflow duct A side close to the downflow fan 6 and a downflow duct B side close to the downflow outlet. The downflow duct 2e includes a first downflow duct 2e1 and a second downflow duct 2e2 that are separated on the downflow duct A side and connected on the downflow duct B side.

[0173] The upper flow path control mechanism includes an upper baffle mechanism 71 rotatably positioned at the connection point between the upper fan duct 2b and the first upper supply air duct 2a1, and an upper volute mechanism 72 capable of circumferentially sliding around a preset rotation axis of the upper fan 5. The upper baffle mechanism 71 has a first upper rotation position and a second upper rotation position when rotating, and the upper volute mechanism 72 has a first upper sliding position and a second upper sliding position when sliding. When the upper baffle mechanism 71 is in the first upper rotation position, the upper return air vent 23 is opened, simultaneously blocking the upper fan duct 2b and the first upper supply air duct 2a1. When the upper baffle mechanism 71 is in the second upper rotating position, the upper return air vent 23 is closed and the upper fan duct 2b and the first upper supply air duct 2a1 are connected. When the upper volute mechanism 72 is in the first upper sliding position, the upper fan duct 2b is connected to the middle air duct 2c while blocking the connection between the upper fan duct 2b and the second upper supply air duct 2a2. When the upper volute mechanism 72 is in the second upper sliding position, the upper fan duct 2b is connected to the second upper supply air duct 2a2 while blocking the connection between the upper fan duct 2b and the middle air duct 2c.

[0174] The downstream flow control mechanism includes a lower baffle mechanism 81 rotatably positioned at the connection point between the downstream fan duct 2d and the first downstream air supply duct 2e1, and a lower volute mechanism 82 capable of circumferentially sliding around a preset rotation axis of the downstream fan 6. The lower baffle mechanism 81 has a first downward rotation position and a second downward rotation position when rotating, and the lower volute mechanism 82 has a first downward sliding position and a second downward sliding position when sliding. When the lower baffle mechanism 81 is in the first downward rotation position, the downstream return air inlet 24 is opened, simultaneously blocking the downstream fan duct 2d and the first downstream air supply duct. When the lower baffle mechanism 81 is in the second lower rotation position, the lower return air vent 24 is closed while simultaneously connecting the lower fan duct 2d and the first lower supply air duct 2e1. When the lower volute mechanism 82 is in the first lower sliding position, the lower fan duct 2d is connected to the middle air duct 2c while simultaneously blocking the connection between the lower fan duct 2d and the second lower supply air duct 2e2. When the lower volute mechanism 82 is in the second sliding position, the lower fan duct 2d is connected to the second lower supply air duct 2e2 while simultaneously blocking the connection between the lower fan duct 2d and the middle air duct 2c.

[0175] In this embodiment, both the upper flow path control mechanism and the lower flow path control mechanism adopt a baffle plus volute motion mode, thereby realizing multiple air supply modes of the air conditioner.

[0176] It should be noted that the worm tongue motion mechanism provided in this embodiment adopts a mature mechanism, and the specific composition and operating principle of the worm tongue motion mechanism will not be described in detail in this embodiment.

[0177] In some implementations, such as Figure 9 and Figure 10As shown, the upper fan 5 and the lower fan 6 are centrifugal fans, and the rotation directions of the upper fan 5 and the lower fan 6 are opposite.

[0178] In some implementations, such as Figure 9 and Figure 10 As shown, the cabinet air conditioner also includes:

[0179] The heat exchange component 9 includes an upper heat exchange section 91 and a lower heat exchange section 92 disposed in the housing channel 3. The upper heat exchange section 91 is opposite to the axial air inlet of the upper fan 5, and the lower heat exchange section 92 is opposite to the axial air inlet of the lower fan 6.

[0180] By placing the heat exchange components in the casing channel 3 and placing them opposite the axial air inlet of the fan, the airflow entering the fan can be fully heat-exchanged, thus improving the heat exchange effect.

[0181] In some embodiments, the upper fan 5 and the lower fan 6 are double-suction centrifugal fans that can be axially inlet from both sides, wherein the heat exchange component 9, which is composed of the upper heat exchange section 91 and the lower heat exchange section 92, is configured as a V-shaped heat exchange component with the notch facing the air inlet of the centrifugal fan.

[0182] In this embodiment, by setting the heat exchange component 9 in a V-shape, the airflow flowing from top to bottom or from bottom to top inside the air conditioner can fully contact the heat exchanger, thereby improving the heat exchange effect of the airflow.

[0183] In some implementations, such as Figure 3 As shown, the aforementioned cabinet air conditioner can be composed of the following components, specifically including: front panel 1a, right side panel 1b, air outlet frame component 1c, lower channel 1d, left side panel 1e, top cover 1f, and chassis 1g. The front panel 1a, right side panel 1b, left side panel 1e, and right side panel 1b form the outer perimeter of the cabinet air conditioner. The top cover 1f is located on the top of the air conditioner, and the chassis 1g is located at the bottom of the air conditioner. The air outlet frame component 1c is located on the top of the air duct component 2, with its upper end connected to the upper air outlet 11 on the air conditioner casing and its lower end connected to the upper air duct opening 21 on the top of the air duct component 2. The lower channel 1d is located at the bottom of the air duct component, with its upper end connected to the lower air duct opening 22 at the bottom of the air duct component 2 and its lower end connected to the lower air outlet 12 at the bottom of the air conditioner casing.

[0184] It should be noted that the air outlet frame component 1c and the lower channel 1d can be either separate or integrally molded with the air duct component. That is, the air outlet frame component 1c and the lower channel 1d can be part of the air duct component.

[0185] It is worth noting that the upper return air vent 23 and lower return air vent 24 mentioned above can also be set on the air outlet frame component 1c or the lower channel 1d, respectively, and can achieve the same air outlet effect.

[0186] This invention proposes an air conditioner with fresh air supply and reversible return air. The fresh air module is placed at the lower rear of the air conditioner, and the air outlet of the fresh air module is located in the housing channel 3 inside the air conditioner. Wind deflectors are set at corresponding positions of the upper air inlet 13 and the lower air inlet 14 of the air conditioner housing. Opening and closing the wind deflectors causes the upper air inlet 13 and the lower air inlet 14 to open and close synchronously.
