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

[0084] At present, the existing air conditioner cannot adjust the fresh air outlet position by detecting the air quality at different positions in the room. The embodiment of the present invention proposes an air outlet control method of a cabinet air conditioner and a cabinet air conditioner, which detects the indoor air quality and the stratification of the indoor air quality, controls the air inlet and outlet of different air vents, realizes different fresh air outlet modes, improves the speed of air conditioning to purify the indoor air quality, and increases the air outlet volume of the air conditioner.

[0085] The following is combined with Figure 1 -Attached Fig.16 The technical solution of this embodiment is elaborated in detail. In the absence of conflict, 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 embodiment of the present invention proposes an air outlet control method for a cabinet air conditioner, wherein the cabinet air conditioner has an upper air outlet on the top and a lower air outlet on the bottom, and the air outlet modes of the air conditioner include a single upper air outlet mode in which the upper air outlet outlet discharges air alone, a single lower air outlet mode in which the lower air outlet outlet discharges air alone, and a simultaneous upper and lower air outlet mode in which the upper and lower air outlet outlets discharge air simultaneously, and the air conditioner further includes a fresh air outlet and an indoor air outlet, the fresh air outlet is connected to the outdoor environment and is used to be controlled to be opened when the air conditioner is in a fresh air mode, and the indoor air outlet is connected to the indoor environment and can be controlled to be opened and closed, wherein the fresh air mode of the air conditioner includes an independent fresh air mode in which the indoor air outlet is closed and a mixed fresh air mode in which the indoor air outlet is opened;

[0088] The air outlet control method includes: when the air conditioner is running in fresh air mode:

[0089] Acquire indoor air quality data, determine whether the indoor air quality data meets the preset air quality index, and determine whether the air conditioner operates in an independent fresh air mode or a mixed fresh air mode based on the determination result;

[0090] The air quality data of the top area of ​​the air conditioner and the air quality data of the bottom area of ​​the air conditioner are obtained, and the air outlet mode of the air conditioner is controlled based on the air quality data of the top area of ​​the air conditioner, the air quality data of the bottom area of ​​the air conditioner and the determined fresh air mode.

[0091] In the embodiment of the present invention, by obtaining the indoor air quality and the stratification of the indoor air quality, and by controlling the air inlet and outlet of different air vents, different fresh air outlet modes are realized, thereby improving the speed of air conditioning to purify the indoor air quality and increasing the air outlet volume of the air conditioner.

[0092] Specifically, in the embodiment of the present invention, by obtaining indoor air quality data and comparing the indoor air quality data with preset air quality indicators, it is determined whether the indoor air quality is seriously polluted. By obtaining the air quality data of the top area of ​​the air conditioner and the air quality data of the bottom area of ​​the air conditioner, it is determined whether the indoor air quality is seriously stratified under the current air quality conditions, so as to selectively select different fresh air modes and different air outlet methods to adjust the indoor air in a targeted manner.

[0093] It should be noted that when the air conditioner in the embodiment of the present invention obtains indoor air quality data, it can obtain air quality data at any location in the room, and the obtained air quality data may include multiple air quality parameters. The embodiment of the present invention does not limit the specific acquisition location and specific air quality parameters.

[0094] In some implementations, determining whether the air conditioner operates in an independent fresh air mode or a mixed fresh air mode based on the judgment result includes:

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

[0096] If the indoor air quality data meets the preset air quality index, the air conditioner is 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 indicators, the indoor air quality is poor. In order to quickly purify the indoor air, the air conditioner enters the independent fresh air mode and the indoor air vents are closed to prevent the poor indoor environment from being sucked into the air conditioner.

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

[0100] In some embodiments, the air outlet mode of the air conditioner includes a dual air outlet mode in which upper and lower air outlets simultaneously discharge air, and a single air outlet mode in which the upper air outlet discharges air alone and the lower air outlet discharges air alone;

[0101] The air quality data of the top area of ​​the air conditioner and the air quality data of the bottom area of ​​the air conditioner are combined to determine the fresh air mode to control the air outlet mode of the air conditioner, including:

[0102] Based on the determined fresh air mode, compare the air quality data C of the top area of ​​the air conditioner 上 and air quality data of the bottom area of ​​the air conditioner C 下 whether the difference between is greater than or equal to a preset difference C2, and based on the comparison result, controlling the air conditioner to discharge air in a double-outlet mode or a single-outlet mode;

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

[0104] That is, when the air conditioner in the embodiment of the present invention is running in the fresh air mode, if the indoor air quality stratification is not serious, the air conditioner can be controlled to discharge air from the upper and lower air outlets at the same time, so as to realize the indoor air embracing fresh air discharge and evenly purify all the indoor air. If the indoor air quality stratification is serious, the fixed-point fresh air delivery can be realized for the area with poor air quality to quickly purify the area with poor air quality.

[0105] In some embodiments, based on the determined fresh air mode, the air quality data C of the top area of ​​the air conditioner is compared. 上 and air quality data of the bottom area of ​​the air conditioner C 下 whether the difference between is greater than or equal to a preset difference C2, and based on the comparison result, controlling the air conditioner to discharge air in a double-outlet mode or a single-outlet mode, including;

[0106] If C 上 -C 下 If the absolute value of the difference is less than the preset difference C2, the air conditioner will blow air in a simultaneous upward and downward blowing mode;

[0107] If C 上 -C 下 The absolute value of the difference between 上 and C 下 The size relationship is based on C 上 and C 下 The size relationship controls the air conditioner to discharge air in a way that the upper air outlet is the only air outlet or the way that the lower air outlet is the only air outlet.

[0108] Specifically, in some embodiments, the upper air outlet single air outlet mode includes a first single upper air outlet mode in which air is taken in through the lower air outlet and air is discharged through the upper air outlet, and a second single upper air outlet mode in which air is closed through the lower air outlet and air is discharged through the upper air outlet;

[0109] The single downwind outlet air outlet mode includes a first single downwind outlet mode in which air enters from the upper air outlet and air is discharged from the lower air outlet, and a second single downwind outlet mode in which air is closed from the upper air outlet and air is discharged from the lower air outlet;

[0110] Based on C 上 and C 下 The size relationship controls the air conditioner to discharge air in a way that the upper air outlet is the only outlet or the lower air outlet is the only outlet, including:

[0111] C-based 上 and C 下 The size relationship and the specific fresh air mode of the air conditioner control the air conditioner to discharge air in 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.

[0112] That is, when there is a problem of uneven stratification in the indoor air quality, it is necessary to consider the specific fresh air mode of the air conditioner, that is, it is necessary to consider whether the air conditioner is running in an independent fresh air mode or a mixed fresh air mode. Since the independent fresh air mode cannot introduce indoor air and the mixed fresh air mode can introduce indoor air, different air outlet methods can be selected according to the specific fresh air mode.

[0113] Specifically, in some embodiments, based on C 上 and C 下 The size relationship and the specific fresh air mode of the air conditioner control the air conditioner to discharge air in the first single upper air outlet mode or the second single upper air outlet mode or the first single lower air outlet mode or the second single lower air outlet mode, including:

[0114] In mixed fresh air mode:

[0115] If C 上 >C 下 When the absolute value of the difference between the two is greater than or equal to the preset difference C2, the air conditioner discharges air in the first single upper air outlet mode;

[0116] If C 上 <C 下 When the absolute value of the difference between the two is greater than or equal to the preset difference C2, the air conditioner discharges air in the first single downward air outlet mode.

[0117] That is, in the mixed fresh air mode, since the indoor air can enter the air conditioner, when one of the upper or lower air outlets is discharging air, the flow control mechanism can be used to make the other one an air inlet, thereby increasing the air intake and air supply of the air conditioner.

[0118] Specifically, in some embodiments, based on C 上 and C 下 The size relationship and the specific fresh air mode of the air conditioner control the air conditioner to discharge air in the first single upper air outlet mode or the second single upper air outlet mode or the first single lower air outlet mode or the second single lower air outlet mode, including:

[0119] In independent fresh air mode:

[0120] If C 上 >C 下 When the absolute value of the difference between the two is greater than or equal to the preset difference C2, the air conditioner discharges air in the second single upper air outlet mode;

[0121] If C 上 <C 下 When the absolute value of the difference between the two is greater than or equal to the preset difference C2, the air conditioner discharges air in the second single downward air outlet mode.

[0122] That is, in the independent fresh air mode, since indoor air cannot enter the air conditioner, one of the upper and lower air outlets is controlled to be closed when the air is discharged, thereby preventing indoor air from entering the air conditioner and affecting the fresh air purification effect of the air conditioner.

[0123] In order to more clearly understand the air outlet control principle of the air conditioner in the embodiment of the present invention, Figure 2 To explain in detail:

[0124] In independent fresh air mode:

[0125] When the upper air quality sensor detects the upper air quality C 上 The lower air quality sensor detects the lower indoor air quality C 下 The difference is positive and the absolute value of the difference is ≥ the set value C2. At this time, the indoor air quality is severely stratified, and the air quality of the upper layer is worse than that of the lower layer. In order to quickly purify the upper layer of indoor air, the downwind outlet at the bottom of the air conditioner is closed, and the upwind outlet at the top of the air conditioner is connected to the fan. Under the joint 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 body shell channel, and blows it out from the upwind outlet under the action of the fan system, so as to realize the fresh air outlet at the upper fixed point and quickly purify the upper air.

[0126] When the upper air quality sensor detects the upper air quality C 上 The lower air quality sensor detects the lower indoor air quality C 下 The difference is negative and the absolute value of the difference is ≥ the set value C2. At this time, the indoor air quality is severely stratified, and the air quality of the lower layer is worse than that of the upper layer. In order to quickly purify the upper layer of indoor air, the upper air vent is closed and the lower air vent is connected to the fan. Under the joint 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 body shell channel. Under the action of the fan system, it is blown out from the lower air vent, realizing the fixed-point outlet of fresh air at the bottom and quickly purifying the lower air.

[0127] When the upper air quality sensor detects the upper air quality C 上 The lower air quality sensor detects the lower indoor air quality C 下 The absolute value of the difference is less than the set value C2. At this time, the indoor air quality is evenly distributed, the upper and lower air vents are opened, the upper air vent is connected to the upper fan system, and the lower air vent is connected to the lower fan system. Under the joint 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 body shell channel. Under the action of the fan system, it is blown out from the upper and lower air vents respectively, realizing the indoor air embracing fresh air output and evenly purifying all the indoor air.

[0128] In mixed fresh air mode:

[0129] If C 上 and C 下 If the absolute value of the difference is less than the preset difference C2, it means that the indoor air quality is evenly distributed up and down without stratification. At this time, the upper air outlet of the air conditioner can be connected to the upper fan system, and the lower air outlet can be connected to the lower fan system. The 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 fuselage shell channel. At the same time, the indoor air enters the air conditioner from the indoor air outlet, enters the fuselage shell channel and mixes with the fresh air in the channel. Under the action of the fan system, it is blown out from the upper air outlet on the top of the air conditioner and the lower air outlet at the bottom of the air conditioner at the same time, realizing the surrounding purification of indoor air quality, allowing users to feel the surrounding cooling and fresh air.

[0130] If C 上 and C 下 If the absolute value of the difference is greater than or equal to the preset difference C2, it means that stratification occurs in the indoor air. Since the indoor air quality is not very bad at this time, indoor wind can be introduced. Therefore, one of the upper or lower air outlets on the top of the air conditioner can be used as an air inlet through the control of the flow control mechanism, thereby increasing the air intake of the air conditioner.

[0131] Specific:

[0132] Taking the air conditioner in cooling mode as an example, when the upper air quality sensor detects the upper air quality C 上 The lower air quality sensor detects the lower indoor air quality C 下 When the absolute value of the difference is ≥ the set value C2, it means that the indoor air quality is seriously stratified. 上 >C 下, indicating that the upper air quality is worse than the lower air quality. 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. The 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 fuselage shell channel. At the same time, the indoor air also enters the fuselage shell channel inside the air conditioner from the indoor air vent and the lower air vent {the indoor air vent will be described in detail below, which includes the upper air inlet and the lower air inlet}. After entering the fuselage shell channel and mixing with the fresh air in the channel, it is blown out from the upper air vent under the action of the fan system, realizing the simultaneous purification of the poor quality air in the upper part during cooling. On the one hand, it increases the cooling air volume, and on the other hand, the air outlet is fresher during cooling. When C 上 <C 下 , indicating 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 outlet is converted into an air inlet, and the lower air outlet is connected to the fan cavity. The 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 fuselage shell channel. The indoor air enters the fuselage shell channel from the indoor air outlet and the upper air outlet, enters the fuselage shell channel and mixes with the fresh air in the channel, and is blown out from the lower air outlet under the action of the fan system, thereby achieving fixed-point purification of indoor air quality during cooling.

[0133] Taking the air conditioner in heating mode as an example, when the upper air quality sensor detects the upper air quality C 上 The lower air quality sensor detects the lower indoor air quality C 下 The absolute value of the difference between the two values ​​is ≥ the set value C2, indicating that the indoor air quality is seriously stratified. 上 <C 下 , indicating that the lower air quality is worse than the upper air quality. 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. The 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 fuselage shell channel. The indoor air enters from the indoor air vent and the upper air vent, enters the fuselage shell channel, and is mixed with the fresh air in the channel. It is blown out from the lower air vent under the action of the fan system, realizing the simultaneous purification of the poor quality air in the lower part during heating. On the one hand, it increases the heating air volume, and on the other hand, the air outlet is fresher during heating, which improves the air conditioning comfort. When C 上 >C 下 At this time, the air quality in the upper part is worse than that in the lower part. The downwind vent at the bottom of the air conditioner is converted into an air inlet, and the upwind vent is connected to the fan cavity. The 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 fuselage shell channel. The indoor air enters from the indoor air vent and the downwind vent, enters the fuselage shell channel, and is mixed with the fresh air in the channel. Then, it is blown out from the upwind vent at the top of the air conditioner under the action of the fan system, thereby achieving fixed-point purification of indoor air quality during heating.

[0134] Further, such as Figure 3-Figure 16 As shown, the second aspect of the embodiment of the present invention further provides a cabinet air conditioner, the cabinet air conditioner has an upper air outlet 11 on the top and a lower air outlet 12 on the bottom, the air outlet mode of the air conditioner includes a single upper air outlet mode in which the upper air outlet 11 outlets air alone, a single lower air outlet mode in which the lower air outlet 12 outlets air alone, and a simultaneous upper and lower air outlet mode in which the upper and lower air outlets outlet air at the same time, 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 used to be controlled to be opened when the air conditioner is in a fresh air mode, the indoor air outlet is connected to the indoor environment and can be controlled to be opened and closed, and the fresh air mode of the air conditioner includes an independent fresh air mode in which the indoor air outlet is closed and a mixed fresh air mode in which the indoor air outlet is opened;

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

[0136] In some embodiments, the cabinet air conditioner comprises:

[0137] A casing 1, wherein an upper air outlet 11 is provided at the top of the casing 1 and a lower air outlet 12 is provided at the bottom;

[0138] The air duct component 2 is arranged inside the casing 1 and defines a body shell channel 3 between the casing 1 and the casing 1. The top of the air duct component 2 is provided with an upper air duct opening 21 connected to the upper air port 11, and the bottom is provided with a lower air duct opening 22 connected to the lower air port 12;

[0139] A flow path control mechanism, 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 lower air supply path that takes in air from the fuselage shell channel 3 and discharges air from the lower air duct opening 22, a single upper air supply path that takes in air from the fuselage shell channel 3 and discharges air from the upper air duct opening 21, and a dual air supply path that takes in air from the fuselage shell channel 3 and discharges air from both the upper air duct opening 21 and the lower air duct opening 22;

[0140] A fresh air module 4, the fresh air module 4 has a fresh air outlet, wherein the air inlet end of the fresh air outlet is used to connect to the outdoor environment, and the air outlet end is connected to the fuselage shell channel 3, wherein the fresh air module 4 can introduce outdoor fresh air into the fuselage shell channel 3 when the air duct component 2 supplies air in different air supply paths;

[0141] The casing 1 is also provided with an indoor air vent connected to the fuselage shell channel 3, wherein the indoor air vent is controlled to be opened when the air conditioner operates in a mixed fresh air mode, and is controlled to be closed when the air conditioner operates in an independent fresh air mode.

[0142] The cabinet air conditioner provided in the embodiment of the present invention can enable the air duct component to form different air supply paths by setting a flow control mechanism in the air duct component, and at the same time set a fresh air module, and connect the fresh air module with the body shell channel of the air conditioner. In this way, when the air conditioner operates in the fresh air mode, the fresh air can enter the air duct component 2 through the body shell channel 3 and follow the air supply path switching of the air duct component to achieve the fresh air supply effect at different positions. At the same time, the indoor air vents on the air conditioner casing 1 can be controlled to open or close. In this way, when the indoor air vents are closed, the fresh air module can serve as the air inlet of the air conditioner to provide air volume for the air conditioner, thereby realizing an independent fresh air supply mode, and when the air inlet is opened, the fresh air module can also provide air intake for the entire air conditioner, thereby realizing a large air volume mixed fresh air supply mode.

[0143] In some embodiments, Fig. 9 and Fig.10 As shown, the indoor air inlet includes an upper air inlet 13 arranged at the top of the casing 1 and / or a lower air inlet 14 arranged at the bottom of the casing 1.

[0144] Preferably, air inlets are provided at the top and the bottom of the casing 1, so that the air intake volume of the entire air conditioner can be increased.

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

[0146] Of course, in some alternative embodiments, the opening and closing of the upper air inlet 13 and the lower air inlet 14 may also be achieved by other mechanisms. For example, on-off valves and other on-off components are provided at 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 embodiments, Fig. 9 and Fig.10 As shown, the cabinet air conditioner has a front side facing the user side when installed, and a rear side opposite to the front side;

[0148] The lower air outlet 21 opens at the bottom front side of the air conditioner, and the fresh air module 4 is arranged at the bottom rear side of the air conditioner.

[0149] By setting the downwind outlet 21 at the front bottom side of the air conditioner, when the air conditioner is discharging air in heating mode, the hot air can fully contact the bottom surface and then rise, thereby improving the heating effect of the air conditioner. By setting the fresh air module 4 at the rear bottom side of the air conditioner, the air inlet pipe of the fresh air module can be easily connected to the outdoors, which facilitates the installation of the pipeline of the fresh air module 4.

[0150] In some embodiments, Figure 5-Figure 8 As shown, the air duct component 2 is formed with an upper air supply duct 2a, an upper fan duct 2b, an intermediate air duct 2c, a lower fan duct 2d and a lower air supply duct 2e which are arranged in sequence from top to bottom and are fluidly connected. The upper part of the upper air supply duct 2a is connected to the upper air outlet 21, and the lower part of the lower air supply duct 2e is connected to the lower air outlet 22;

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

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

[0153] The downflow path control mechanism can connect the downfan duct 2d and the downsupply air duct 2e while blocking the connection between the downfan duct 2d and the middle duct 2c. The downflow path control mechanism can also connect the downfan duct 2d and the middle duct 2c while blocking the downfan duct 2d and the downsupply air duct 2e.

[0154] By setting the upper flow path control mechanism and the lower flow path control mechanism, the air duct component can achieve the air supply effect of having different air supply paths. Specifically:

[0155] When the air conditioner is required to achieve the effect of delivering air simultaneously from top to bottom, the upper flow path control mechanism can be controlled to make the upper fan duct 2b connected to the upper air supply duct 2a while blocking the connection between the upper fan duct 2b and the middle air duct 2c, and the lower flow path control mechanism can be controlled to make the lower fan duct 2d connected to the lower air supply duct 2e while blocking the connection between the lower fan duct and the middle air duct, and then the upper fan in the upper fan duct and the lower fan in the lower fan duct can be started at the same time, as shown in 11- Fig.14 As shown, the air conditioner can achieve the effect of delivering air from top to bottom at the same time. When fresh air needs to be introduced, the fresh air module 4 can be opened to introduce fresh air from the outside into the room. It is worth noting that when the air conditioner delivers fresh air from top to bottom at the same time, different modes of fresh air delivery effects can be achieved by controlling the opening and closing of the air inlet of the air conditioner housing. Specifically, Fig.11 As shown, when the independent fresh air mode is required, the upper air inlet 13 and the lower air inlet 14 on the air conditioner housing can be closed, and only the fresh air module 4 takes in air. Fig.14 As shown, when the mixed fresh air mode needs to be implemented, the upper air inlet 13 and the lower air inlet 14 on the air conditioner housing can be opened. At this time, air is not only taken in by the fresh air module 4, but also by the air inlet on the air conditioner housing.

[0156] When the air conditioner is required to achieve a single upper air supply effect, the upper fan duct 2b can be controlled by controlling the upper flow control mechanism to block the connection between the upper fan duct 2b and the middle air duct 2c while connecting the upper air supply duct 2a, and then the upper fan in the upper fan duct is started separately. At this time, the air duct component can achieve a single upper air supply effect. At the same time, when fresh air needs to be introduced, the fresh air module 4 can be opened to introduce the outside fresh air into the room. It is worth noting that when the air duct component introduces the outside fresh air in the single upper air supply, the fresh air supply effect of different modes can be achieved by controlling the opening and closing of the air inlet of the air conditioner housing. Specifically, when it is necessary to realize the independent fresh air mode, the air inlet on the air conditioner housing can be closed, and only the fresh air module 4 is inlet at this time. More specifically, when it is necessary to realize the mixed fresh air mode, the air inlet on the air conditioner housing can be opened, and at this time, not only the fresh air module 4 is inlet, but also the air inlet on the air conditioner housing is inlet.

[0157] When the air conditioner is required to achieve a single down-air supply effect, the down-flow control mechanism can be controlled to make the down-fan duct 2d block the connection between the down-fan duct 2d and the middle duct 2c while connecting the down-air supply duct 2e, and then start the down-fan in the down-fan duct separately. At this time, the duct component can achieve a single down-air supply effect. At the same time, when fresh air needs to be introduced, the fresh air module 4 can be opened to introduce fresh air from the outside into the room. It is worth noting that when the duct component introduces fresh air from the outside in the single down-air supply, different modes of fresh air supply effects can be achieved by controlling the opening and closing of the air inlet of the air conditioner housing. Specifically, when it is necessary to achieve an independent fresh air mode, the air inlet on the air conditioner housing can be closed, and only the fresh air module 4 is allowed to enter. More specifically, when it is necessary to achieve a mixed fresh air mode, the air inlet on the air conditioner housing can be opened, and at this time, not only the fresh air module 4 enters the air, but also the air inlet on the air conditioner housing enters the air.

[0158] It can be seen that when the air conditioner in this embodiment delivers fresh air, the fresh air introduced from the outside can follow the flow path switching of the air duct component to flow to different positions in the room, thereby achieving a position-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 also be selected. At the same time, since the exhaust side of the fresh air module in this embodiment is directly connected to the fuselage shell channel on the air inlet side of the air duct component, when the air conditioner runs the 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 fuselage shell channel and then uniformly discharged into the room, so that in this mode, the air supply volume of the air conditioner can be increased and the air outlet effect can be improved.

[0159] In some embodiments, Figure 5-Figure 8As shown, the upper flow path control mechanism can also connect the upper air supply duct 2a and the middle air duct 2c while connecting the upper fan duct 2b and the upper air supply duct 2a, and the upper flow path control mechanism can also block the connection between the upper air supply duct 2a and the middle air duct 2c while blocking the upper fan duct 2b and the upper air supply duct 2a;

[0160] The downflow path control mechanism can also connect the lower fan duct 2d and the lower air supply duct 2e while connecting the lower air supply duct 2e and the middle air duct 2c. The downflow path control mechanism can also block the connection between the lower air supply duct 2e and the middle air duct 2c while blocking the lower fan duct 2d and the lower air supply duct 2e.

[0161] In this embodiment, the above-mentioned configurations are performed on the upper flow path control mechanism and the lower flow path control mechanism, which has the following advantages:

[0162] When the air conditioner is required to achieve a single upward 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, the upper fan duct 2b and the middle air duct 2c are blocked while the upper air supply duct 2a and the middle air duct are connected. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started synchronously. In this way, the lower fan in the lower fan duct 2d can discharge the inhaled air flow through the middle air duct 2c into the upper air supply duct 2a and finally discharge it from the upper side during operation, thereby improving the air supply power of the air conditioner during single upward air supply, and then improving the air supply distance and air supply intensity of the air conditioner during single upward air supply.

[0163] Similarly, when the air conditioner is required to achieve a single downward air supply effect, the lower fan duct 2d and the lower air supply duct 2e can be connected by controlling the lower flow path control mechanism, and at the same time, the lower fan duct 2d and the middle air duct 2c are blocked while the lower air supply duct 2e and the middle air duct 2c are connected, and then the upper fan in the upper fan duct and the lower fan in the lower fan duct are started synchronously, so that the upper fan in the upper fan duct 2b can discharge the inhaled air flow through the middle air duct 2c into the lower air supply duct 2e during operation and finally discharge it from the lower side, thereby improving the air supply power of the air conditioner during single upward air supply, and then improving the air supply distance and air supply intensity of the air conditioner during single upward air supply.

[0164] In some embodiments, Figure 5-Figure 8 As shown, the upper air vent 11 and the lower air vent 12 can be controlled to be opened or closed; an upper return air vent 23 connecting the fuselage shell channel 3 and the upper air duct 2a is provided on the air duct wall of the upper air supply duct 2a, and a lower return air vent 24 connecting the fuselage shell channel 3 and the lower air duct 2e is provided on the air duct wall of the lower air supply duct 2e;

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

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

[0167] In this embodiment, by setting the return air outlets on the duct walls of the upper air duct 2a and the lower air duct 2e, and further setting the upper flow path control mechanism and the lower flow path control mechanism, the air supply volume of the air conditioner can be further increased when the air is discharged from only the upper or lower side. Specifically:

[0168] like Fig.10 and Fig.14 As shown, when the air conditioner needs to achieve a single upper 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, and the upper air supply duct 2a and the middle air duct 2c are connected while the upper fan duct 2b and the middle air duct 2c are blocked, and the upper return air outlet 23 is closed accordingly. Then, the lower fan duct 2d and the lower air supply duct 2e are disconnected by controlling the lower flow path control mechanism, and the lower return air outlet 24 is opened while the lower air supply duct 2e and the middle air duct 2c are blocked. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started synchronously, so that the lower fan in the lower fan duct 2d can suck the air at the bottom of the air conditioner into the lower air supply duct 2e when it is running. The air entering the lower air supply duct 2e is sucked into the fan of the duct component after passing through the lower return air outlet 24 and the fuselage shell channel in turn, and is finally discharged from the top of the air conditioner, thereby increasing the air supply volume of the air conditioner when the single upper air supply is performed.

[0169] Similarly, if Fig.12 and Fig.16 As shown, when the air conditioner needs to achieve a single downward air supply effect, the lower fan duct 2d and the lower air supply duct 2e can be connected by controlling the lower flow path control mechanism, and the lower air supply duct 2e and the middle air duct 2c are connected while the lower fan duct 2d and the middle air duct 2c are blocked, and the lower return air outlet 24 is closed accordingly. Then, the upper fan duct 2b and the upper air supply duct 2a are disconnected by controlling the upper flow path control mechanism, and the upper return air outlet 23 is opened while the upper air supply duct 2a and the middle air duct 2c are blocked. Then, the upper fan in the upper fan duct and the lower fan in the lower fan duct are started synchronously, so that the upper fan in the upper fan duct 2b can suck the air from the top of the air conditioner into the upper air supply duct 2a when it is running. The air entering the upper air supply duct 2a is sucked into the fan of the duct component after passing through the upper return air outlet 23 and the fuselage shell channel in turn, and is finally discharged from the bottom of the air conditioner, thereby increasing the air supply volume of the air conditioner when the air conditioner is supplied from downward only.

[0170] In some embodiments, Figure 4-Figure 7 As shown, the cabinet air conditioner further includes an upper fan 5 disposed in the upper fan air duct 2b and a lower fan 6 disposed in the lower fan air 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 outlet 21. The upper air supply duct 2a includes a first upper air supply duct 2a1 and a second upper air supply duct 2a2 which are separated at the upper air supply duct A side and connected at the upper air supply duct B side.

[0172] The lower air supply duct 2e has a lower air supply duct A side close to the lower fan 6 and a lower air supply duct B side close to the lower air outlet. The lower air supply duct 2e includes a first lower air supply duct 2e1 and a second lower air supply duct 2e2 which are separated at the lower air supply duct A side and connected at the lower air supply duct B side.

[0173] The upper flow path control mechanism includes an upper baffle mechanism 71 rotatably arranged at the connecting position between the upper fan duct 2b and the first upper air supply duct 2a1, and an upper volute mechanism 72 capable of circumferentially sliding around the 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 located at the first upper rotation position, the upper return air outlet 23 is opened while blocking the upper fan duct 2b and the first upper air supply duct 2a1. When the upper baffle mechanism 71 is located at the second upper rotation position, the upper return air port 23 is closed and connected to the upper fan duct 2b and the first upper air supply duct 2a1; when the upper volute mechanism 72 is located at 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 air supply duct 2a2; when the upper volute mechanism 72 is located at the second upper sliding position, the upper fan duct 2b is connected to the second upper air supply duct 2a2 while blocking the connection between the upper fan duct 2b and the middle air duct 2c;

[0174] The lower flow path control mechanism includes a lower baffle mechanism 81 which is rotatably arranged at the connecting position between the lower fan duct 2d and the first lower air supply duct 2e1, and a lower volute mechanism 82 which can slide circumferentially around the preset rotation axis of the lower fan 6. The lower baffle mechanism 81 has a first lower rotation position and a second lower rotation position when rotating, and the lower volute mechanism 82 has a first lower sliding position and a second lower sliding position when sliding. When the lower baffle mechanism 81 is located at the first lower rotation position, the lower return air outlet 24 is opened while blocking the lower fan duct 2d and the first lower air supply duct 2e1. When the lower baffle mechanism 81 is located at the second lower rotating position, the lower return air outlet 24 is closed and connected to the lower fan duct 2d and the first lower upper air supply duct 2e1; when the lower volute mechanism 82 is located at the first lower sliding position, the lower fan duct 2d remains connected to the middle air duct 2c while blocking the connection between the lower fan duct 2d and the second lower air supply duct 2e2; when the lower volute mechanism 82 is located at the second sliding position, the lower fan duct 2d is connected to the second lower air supply duct 2e2 while blocking the connection between the lower fan duct 2d and the middle air duct 2c.

[0175] That is, the upper flow path control mechanism and the lower flow path control mechanism in this embodiment both adopt the movement mode of the baffle plate plus the volute tongue, thereby realizing a variety of air supply modes of the air conditioner.

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

[0177] In some embodiments, Fig. 9 and Fig.10 As shown, the upper fan 5 and the lower fan 6 are centrifugal fans, and the upper fan 5 and the lower fan 6 have opposite rotation directions.

[0178] In some embodiments, Fig. 9 and Fig.10 As shown, the cabinet air conditioner also includes:

[0179] The heat exchange component 9 includes an upper heat exchange portion 91 and a lower heat exchange portion 92 which are arranged in the fuselage shell channel 3. The upper heat exchange portion 91 is opposite to the axial air inlet of the upper fan 5, and the lower heat exchange portion 92 is opposite to the axial air inlet of the lower fan 6.

[0180] By arranging the heat exchange component in the fuselage shell channel 3 and opposite to the axial air inlet of the fan, the airflow before entering the fan can be fully heat exchanged, thereby improving the heat exchange effect.
