[0060] In the description of this embodiment, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0061] Figure 1 This is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention, and in conjunction with... Figure 2-13 The present invention provides a control method for an air conditioner, the air conditioner including two horizontally arranged air outlet columns 10.

[0062] The control method includes the following steps: Step S11, obtaining the ambient temperature of multiple preset areas indoors; Step S12, controlling one or two air outlet columns to output air according to the ambient temperature of each preset area.

[0063] Specifically, "obtaining the ambient temperature of multiple preset indoor areas" refers to dividing the entire indoor area into preset zones and obtaining the ambient temperature of each preset zone. "Controlling one or two air outlet columns to output air based on the ambient temperature of each preset zone" includes the following two situations: ① controlling one air outlet column to output air based on the ambient temperature of each preset zone; ② controlling two air outlet columns to output air based on the ambient temperature of each preset zone.

[0064] In this embodiment, on the one hand, compared with the single air outlet used in the prior art, the present invention uses two horizontally arranged dual air outlet columns. Therefore, the present invention facilitates the adjustment of the air outlet angle of the air conditioner and has a large adjustment range, and can increase the air volume. On the other hand, the control method of the present invention controls the operation of one or two air outlet columns according to the ambient temperature of multiple preset areas. It can not only control one air outlet column to output heat exchange air while the other air outlet column outputs non-heat exchange air or does not output air, but also control both air outlet columns to output heat exchange air simultaneously. This solves the problem of the single air supply mode in existing air conditioners, can meet the diverse air supply needs of users, and can improve the uniformity of indoor ambient temperature, thereby meeting the needs of different users and improving the user experience.

[0065] Furthermore, the control method of the present invention has the advantages of simple control procedures and easy execution.

[0066] In some optional embodiments of the present invention, the indoor space where the indoor unit of the air conditioner is located is divided into multiple preset areas.

[0067] Specifically, the indoor space is divided into N×M (N refers to the number of horizontal preset areas and M refers to the number of vertical preset areas) preset areas, that is, the indoor space is divided into a grid.

[0068] For example, multiple preset areas indoors can be preset areas arranged in a 3×3 pattern, or preset areas arranged in a 2×4 pattern, a 4×2 pattern, a 4×4 pattern, a 5×4 pattern, a 4×5 pattern, a 5×5 pattern, or other horizontal and vertical preset areas.

[0069] In some optional embodiments of the present invention, an infrared temperature sensor is used to detect the ambient temperature of each preset area. In some alternative embodiments, a temperature sensor can be set in each preset area to obtain the ambient temperature of multiple preset areas indoors.

[0070] In some optional embodiments of the present invention, the step of controlling one or two air outlet columns to supply air according to the ambient temperature of each preset area includes: controlling the air conditioner to operate in a compensation air supply mode according to the ambient temperature of each preset area.

[0071] The method of controlling the air conditioner to operate in a compensated air supply mode based on the ambient temperature of each preset area includes the following steps: obtaining the average indoor ambient temperature based on the ambient temperature of each preset area; calculating the absolute value of the difference between the ambient temperature of each preset area and the average indoor ambient temperature; and controlling one or two air outlet columns to supply air towards the preset area with the largest absolute value of the difference.

[0072] Specifically, among all preset areas, the preset area with the largest absolute value of the temperature difference from the average indoor temperature is designated as the area to be compensated. If the temperature deviation between the area to be compensated and the other preset areas is large, it indicates that the area to be compensated is a region with heat loss, affecting the uniformity of the indoor environment. Therefore, in this embodiment, by identifying the preset area with the largest absolute value of the temperature difference from the average indoor temperature and controlling one or two air outlets to direct airflow towards it, temperature compensation can be performed on the aforementioned preset area (the area to be compensated), thereby further improving the uniformity of the indoor temperature. In other words, this embodiment can identify, detect, and compensate for the temperature of preset areas in the indoor environment that suffer from heat damage, thereby improving user comfort.

[0073] Preferably, in some optional embodiments of the present invention, the step of "obtaining the average indoor ambient temperature based on the ambient temperature of each preset area; calculating the absolute value of the difference between the ambient temperature of each preset area and the average indoor ambient temperature" includes: firstly, calculating the average ambient temperature of each preset area within a set time period to obtain a first average temperature; and based on the first average temperature of each preset area, obtaining the average indoor ambient temperature within the set time period and recording it as a second average temperature; then calculating the absolute value of the difference between the first average temperature and the second average temperature of each preset area. In some alternative embodiments, the average indoor temperature at a certain moment and the ambient temperature of each preset area can also be used as control factors.

[0074] In this embodiment, the above settings reduce misjudgments and improve control accuracy, thereby making the indoor ambient temperature more uniform. In other words, compared to using the average indoor temperature at a certain moment and the ambient temperature of each preset area as control factors, this embodiment uses the average indoor ambient temperature over a set time period and the average temperature of each preset area as control factors. This allows for the identification of the area with the greatest heat damage, thus avoiding misjudgments of areas requiring compensation.

[0075] In some optional embodiments of the present invention, the two air outlet columns 10 are spaced apart to form an air intake gap 20 between them. When the two air outlet columns 10 blow air forward, the negative pressure drives the air in the air intake gap 20 to flow forward, thereby mixing this air with the air blown out by the two air outlet columns 10. During cooling, this increases the air outlet temperature and prevents the air from being too "hard," producing a "soft" air effect.

[0076] In some optional embodiments of the present invention, each air outlet column 10 is provided with an air outlet duct and a bypass duct, each air outlet duct is provided with a heat exchanger 15, and each air outlet column 10 has a first air outlet 11 communicating with the air outlet duct and a second air outlet 17 communicating with the bypass duct on its front side, and the second air outlet 17 is located on the side of the first air outlet 11 away from the other air outlet column 10; the first air outlet 11 and the second air outlet 17 are both vertical strips; the inlet of the bypass duct is connected to the air outlet duct.

[0077] The method of controlling one or two air outlet columns to output air according to the ambient temperature of each preset area includes: controlling the first air outlet and / or the second air outlet of one or two air outlet columns to output air according to the ambient temperature of each preset area.

[0078] In this embodiment, "controlling the first air outlet and / or the second air outlet in one or two air outlet columns to discharge air according to the ambient temperature of each preset area" includes the following situations: ① controlling the first air outlet or the second air outlet in one air outlet column to discharge air according to the ambient temperature of each preset area; ③ controlling the first air outlet and the second air outlet in one air outlet column to discharge air according to the ambient temperature of each preset area; ④ controlling the first air outlet and the second air outlet in two air outlet columns to discharge air according to the ambient temperature of each preset area; ⑤ controlling the first air outlet or the second air outlet in two air outlet columns to discharge air according to the ambient temperature of each preset area.

[0079] In this embodiment, the two air outlet columns 10 are symmetrically arranged about a vertically extending reference plane. The symmetrical arrangement of the air outlet columns 10 gives the vertical air conditioner indoor unit a stable and aesthetically pleasing appearance, appealing to Chinese tastes. The vertical air outlets prevent indoor temperature stratification, ensuring a more uniform indoor temperature throughout the unit. Each air outlet column has two outlets, which not only expands the adjustable range of the air outlet angle but also increases the diversity of air delivery methods, thus better meeting the diverse needs of users.

[0080] In some optional embodiments of the present invention, controlling the airflow from the first air outlet and / or the second air outlet in one or two air outlet columns according to the ambient temperature of each preset area includes: in response to the air conditioner being turned on, obtaining the average indoor ambient temperature according to the ambient temperature of each preset area; calculating the absolute value of the temperature difference between the current average indoor ambient temperature and the set temperature of the air conditioner; and controlling the airflow from the first air outlet and / or the second air outlet in one or two air outlet columns according to the absolute value of the temperature difference.

[0081] Specifically, when the air conditioner starts, the average indoor temperature is obtained based on the ambient temperature of each preset zone. The absolute value of the temperature difference between the current average indoor temperature and the set temperature of the air conditioner is used as a control factor to control the air outlet mode of the air conditioner: controlling the first and second air outlets in one air outlet column to simultaneously emit air; or controlling the first or second air outlet in one air outlet column to emit air; or controlling the first or second air outlet in one air outlet column to emit air, and controlling the first or second air outlet in another air outlet column to emit air; or controlling the first and second air outlets in one air outlet column to emit air, and controlling the first or second air outlet in another air outlet column to emit air; or controlling the first and second air outlets in two air outlet columns to emit air.

[0082] In this embodiment, when the air conditioner is first turned on, the air outlet mode of the air conditioner is controlled by the absolute value of the temperature difference between the average indoor temperature and the set temperature of the air conditioner, so that the air conditioner can quickly reach the set temperature.

[0083] In some optional embodiments of the present invention, a wind guide device is provided at the first air outlet, and a micro-wind structure is provided at the second air outlet.

[0084] Specifically, by installing an air guide device at the first air outlet, the air outlet angle can be easily adjusted, thereby further increasing the adjustment range of the air outlet angle. A micro-wind structure is installed at the second air outlet, so that the air exiting through the second air outlet 17 blows out towards the front side of the second air outlet 17. The air entering the bypass ventilation duct is dispersed by the micro-wind structure 18, becoming a micro-wind, thus making the exit air more "soft".

[0085] In this embodiment, controlling the airflow from the first air outlet and / or the second air outlet in one or both air outlet columns based on the absolute value of the temperature difference includes: if the absolute value of the temperature difference is greater than a first preset value, controlling the air conditioner to output air in the maximum airflow mode; if the absolute value of the temperature difference is greater than or equal to a second preset value and less than or equal to a first preset value, controlling the air conditioner to output air in the comfort airflow mode.

[0086] The maximum airflow mode includes: such as Figure 6 and Figure 11 As shown, each air guide device is controlled to extend in the front-to-back direction so that air is discharged from the first air outlet and the second air outlet of the two air outlet columns, and the first air volume and the first wind speed are executed.

[0087] The comfort air delivery modes include: such as Figure 4 and Figure 13 The two first air outlets are closed to allow air to flow from the second air outlets of the two air outlet columns, and a second air volume and a second wind speed are executed.

[0088] Among them, the first air volume is greater than the second air volume, and the first wind speed is greater than the second wind speed.

[0089] For example: the first preset value is 2℃, the second preset value is 1℃; the first air volume is 1800m³ / h. 3 / h, the first wind speed is 6.4m / s, and the second air volume is 1400m³ / h. 3 / h, the second wind speed is 3.5m / s.

[0090] In this embodiment, the maximum airflow mode can also be called the rapid cooling and heating mode. When the air conditioner is running in the maximum airflow mode, the indoor temperature can be quickly reached the set temperature. The comfortable air supply mode can also be called the gentle breeze mode. When the air conditioner is running in the comfortable air supply mode, the two first air outlets are closed and the two second air outlets are discharging air. The air blown out by the air conditioner is a "soft" breeze, which can improve comfort.

[0091] In some alternative embodiments of the present invention, the air guiding device includes at least one air guiding plate.

[0092] In some alternative embodiments of the invention, the micro-wind structure includes a grille. In some alternative embodiments, the micro-wind structure includes a plurality of arc-shaped plates, the plurality of arc-shaped plates being parallel and protruding forward toward the first air outlet.

[0093] In some alternative embodiments of the present invention, an air intake structure is provided at the inlet of the bypass ventilation duct. The air intake structure can disperse the air passing through the inlet of the bypass ventilation duct, thereby making the air blown out of the second air outlet 17 "softer".

[0094] Preferably, the air inlet structure is a micro-perforated plate. This micro-perforated plate has a good effect on dispersing the air passing through the bypass ventilation duct inlet, thereby making the air blown out of the second air outlet 17 "softer".

[0095] In some optional embodiments of the present invention, the control method further includes: in response to the air conditioner discharging air in the maximum air volume mode, determining whether there is a user within a preset distance from the air conditioner; if so, determining the direction of the user relative to the air conditioner, and controlling the air discharging mode of the air conditioner according to the direction of the user; if not, controlling the air conditioner to continue discharging air in the maximum air volume mode.

[0096] Specifically, when the air conditioner is operating at maximum airflow, it can determine whether there is a user within a preset distance after a short period of time, and adjust the existing airflow mode accordingly. If there is a user within the preset distance, the existing airflow mode is changed; if there is no user within the preset distance, the existing airflow mode is maintained.

[0097] For example, the preset distance is 1 to 2m (it can be 1m, 1.1m, 1.2m, 1.5m, 1.7m or 2.0m), preferably, the preset distance is 1m.

[0098] In this embodiment, the above settings can further improve the user experience.

[0099] Preferably, in some optional embodiments of the present invention, each of the air outlet columns has a first air guide surface connected to the corresponding first air outlet edge away from the other air outlet column.

[0100] The method of controlling the air conditioner's airflow mode based on the user's direction includes: if the user is located in front of the air conditioner, controlling the air conditioner to output air in a wide-angle surround airflow mode. The wide-angle surround airflow mode includes: Figure 8 and Figure 12 As shown, both the first and second air outlets of the two air outlet columns are controlled to emit air, and the air guiding devices are controlled to tilt in the direction of the corresponding first air guiding surface, so that the air outlets of the two air outlet columns are directed away from each other.

[0101] The method of controlling the air outlet mode of the air conditioner according to the user's direction further includes: if the user is located on one side of the air conditioner, controlling the first air outlet closer to the user to close, so that air is discharged from the two second air outlets and the first air outlet farther away from the user (e.g., Figure 5 (As shown). Further, the two air outlet columns are controlled to operate at a fourth wind speed and a fourth air volume, where the fourth wind speed is less than the first wind speed and the fourth air volume is less than the first air volume.

[0102] For example, if the user is located on the left side of the air conditioner, the first air outlet on the left side of the air conditioner will be closed, while the two second air outlets and the first air outlet on the right side of the air conditioner will be controlled to release air. This setting avoids blowing high-intensity cold air directly onto the user, instead providing a gentle breeze from the side, thereby improving the user experience.

[0103] Further preferably, in some optional embodiments of the present invention, the control method further includes: when the air conditioner continues to blow air in the maximum air volume mode, if the average indoor temperature is equal to the set temperature, determining whether the ambient temperature of each preset area and the average indoor temperature meet preset conditions; if the preset conditions are met, controlling the air conditioner to blow air in the cooling mode.

[0104] The cooling mode includes controlling the two air outlet columns to operate at a third wind speed and a third air volume, where the third wind speed is lower than the first wind speed and the third air volume is lower than the first air volume. For example, the third air volume is 800m³ / h. 3 / h.

[0105] The preset conditions include: within a preset time period, the absolute value of the temperature difference between the average indoor temperature and the set temperature of the air conditioner is less than a third preset value, and the temperature fluctuation value of the ambient temperature in each preset area is less than a preset fluctuation value. For example, the third preset value is 2℃, and the preset fluctuation value is 1.5.

[0106] Specifically, within a preset time period, the temperature fluctuation value of the ambient temperature in each preset area is less than a preset fluctuation value. The temperature fluctuation value of the ambient temperature in each preset area is represented by the standard deviation of the ambient temperature in that preset area over the preset time period. That is, the temperature fluctuation value of the ambient temperature in the preset area is denoted as S. tj It is expressed as the standard deviation of the temperature at a single measuring point over a specified time period, and is calculated using the following formula:

[0107]

[0108] In the formula, s tj --Temperature fluctuation at measuring point j; t tj --Instantaneous temperature at measuring point j, °C; t j --Measured temperature of measuring point j (average temperature over the test period), ℃; m—number of temperature samples collected at a specific measuring point within a specified time period.

[0109] Temperature fluctuation is an indicator of how indoor ambient temperature changes over time. The greater the temperature fluctuation value, the more pronounced the fluctuations in room temperature.

[0110] In this embodiment, when the absolute value of the temperature difference between the average indoor temperature and the set temperature of the air conditioner, as well as the temperature fluctuation value of the ambient temperature in each preset area, meet the preset conditions, it indicates that the overall temperature fluctuation of the average indoor temperature is small. In other words, the average indoor temperature tends to be within a certain range. At this time, controlling the air conditioner to blow air in the cooling mode can save energy while ensuring user comfort.

[0111] More preferably, in some optional embodiments of the present invention, the control method further includes: in response to the air conditioner discharging air in a cooling mode, controlling the air conditioner to operate in a compensating air supply mode according to the ambient temperature of each preset area.

[0112] The air conditioner operation compensation mode based on the ambient temperature of each preset area includes the following steps: calculating the absolute value of the difference between the ambient temperature of each preset area and the average indoor ambient temperature; controlling one or two air outlet columns to direct airflow towards the preset area with the largest absolute value of the difference.

[0113] Specifically, after the air conditioner has been running in cooling mode for a second time, the air conditioner is controlled to operate in compensation mode according to the ambient temperature of each preset area, thereby improving the uniformity of indoor ambient temperature.

[0114] In some optional embodiments of the present invention, the air conditioner further includes a flow path control device configured to control the two heat exchangers to operate simultaneously or only one of the heat exchangers to operate, wherein when either air outlet column is not discharging air, the corresponding heat exchanger also does not operate. The heat exchanger in the first air outlet column is the first heat exchanger, and the heat exchanger in the second air outlet column is the second heat exchanger.

[0115] In this embodiment, since each air outlet column includes a heat exchanger, the two air outlet columns can discharge heat-exchange air individually or simultaneously. In some alternative embodiments of the invention, the two air outlet columns share a single heat exchanger.

[0116] Furthermore, each air outlet column also includes a fan.

[0117] In a preferred embodiment of the present invention, the control method for an air conditioner includes the following steps:

[0118] Step S21: Turn on the air conditioner.

[0119] Step S22, store the air conditioner's operating mode: cooling mode / heating mode, so that it can be automatically defaulted to the previous operating mode the next time it is turned on.

[0120] Step S23: Use infrared light to divide the indoor space where the indoor unit of the air conditioner is located into multiple preset areas; and use an infrared temperature sensor to detect the ambient temperature of each preset area.

[0121] Step S24: Obtain the average indoor ambient temperature based on the ambient temperature of each preset area.

[0122] Step S25: Calculate the absolute value of the temperature difference between the current average indoor temperature and the set temperature.

[0123] Step S26: Control the airflow from the first air outlet and / or the second air outlet in one or two air outlet columns based on the absolute value of the temperature difference.

[0124] Step S261: If the absolute value of the temperature difference is greater than 2℃, control the air conditioner to output air in the maximum air volume mode.

[0125] In step S262, if 1℃≤absolute temperature difference≤2℃, control the air conditioner to supply air in the comfort air supply mode; and after a certain period of time, repeat step S24.

[0126] Following step S261, the control method further includes the following steps:

[0127] Step S27: Determine if there are any users within 1m of the air conditioner.

[0128] Step S281: If yes, determine the direction of the user relative to the air conditioner, and control the air outlet mode of the air conditioner according to the direction of the user. After a certain period of time, re-execute step S24.

[0129] Step S282: If not, control the air conditioner to continue to output air in the maximum air volume mode.

[0130] Following step S282, the control method further includes the following steps:

[0131] Step S291: If the average indoor temperature is equal to the set temperature, determine whether the ambient temperature of each preset area and the average indoor temperature meet the preset conditions. If the preset conditions are met, control the air conditioner to blow air in the cooling mode. If the preset conditions are not met, repeat step S24.

[0132] Step S292: After the second time of air supply in cooling mode, control the air conditioner to operate in compensated air supply mode according to the ambient temperature of each preset area.

[0133] Step S293: Detect the current environment information. Based on the detected environment information, re-execute step S24 or re-execute step S291.

[0134] In this embodiment, the following temperature control objectives can be achieved: at a distance of one meter from the air outlet of the air conditioner, the ambient temperature of the corresponding preset area is ≥23℃, and the air velocity V is ≤1.5m / s, so as to achieve a gentle airflow and a user experience that is cool but not cold.

[0135] Figure 2 This is a schematic front view of an air conditioner according to an embodiment of the present invention, with reference to... Figures 3 to 13 The present invention also provides an air conditioner, which includes a control device. The control device includes a memory and a processor. The memory stores a control program, which, when executed by the processor, is used to implement the control method of the air conditioner as described in any of the above embodiments.

[0136] like Figure 3-13 As shown, in some optional embodiments of the present invention, the air conditioner includes two air outlet columns 10, which are respectively a first air outlet column and a second air outlet column. Each air outlet column 10 has multiple air outlets on its front side. When the two air outlet columns are vertically arranged, they are symmetrically arranged about a vertically extending reference plane, and are respectively the first air outlet column and the second air outlet column. When the two air outlet columns are horizontally arranged, they are symmetrically arranged about a horizontally extending reference plane. The symmetrical arrangement of the air outlet columns 10 makes the air conditioner's design stable and conforms to the aesthetic preferences of Chinese people.

[0137] Furthermore, in some embodiments of the present invention, such as Figure 10 As shown, the two air outlet columns 10 are spaced apart to form an air intake gap 20 between them. When the two air outlet columns 10 blow air forward, the negative pressure drives the air in the air intake gap 20 to flow forward, so that this air mixes with the air blown out by the two air outlet columns 10. During cooling, this reduces the air outlet temperature and prevents the air from being too "hard", producing a "soft" air effect.

[0138] In some embodiments of the present invention, each air outlet column 10 includes a first air outlet 11, an air outlet duct, and a heat exchanger. The air outlet duct communicates with the first air outlet 11, and the heat exchanger 15 is disposed within the air outlet duct. The air conditioner also includes a flow path control device configured to control both heat exchangers to operate simultaneously or only one heat exchanger to operate. When either air outlet column is not discharging heat-exchange air, the corresponding heat exchanger also does not operate.

[0139] In these embodiments, each first air outlet 11 can discharge air independently. The air conditioner can discharge air from a single first air outlet 11 or from both first air outlets 11 simultaneously. When both discharge air simultaneously, the air conditioner can have a larger air volume and a wider air discharge range. The flow path control device controls the operating state of the heat exchanger 15 by controlling the on / off state of the working fluid flow path in the heat exchanger 15. The flow path control device can control both heat exchangers 15 to operate simultaneously, in which case both first air outlets 11 will simultaneously blow out heat exchange air. The flow path control device can also control only one of the two heat exchangers 15 to operate. In this case, when both first air outlets 11 discharge air simultaneously, the heat exchange air and non-heat exchange air can be mixed or blown separately to their respective designated areas. Mixed air discharge can make the outlet air temperature close to room temperature, avoiding discomfort caused by heat exchange air blowing directly on the user. Heat exchange air and non-heat exchange air can be blown separately to their respective designated areas, which can meet the different air discharge needs of users in different locations. The above settings enable the air conditioner to have multiple air discharge modes, which can meet more user needs.

[0140] like Figure 3 As shown, in some embodiments of the present invention, two heat exchangers 15 are arranged in parallel. The flow path control device includes a three-way valve 34. The three-way valve 34 has three openings, namely a first opening, a second opening, and a third opening. The first opening is connected to a four-way valve, and the second and third openings are respectively connected to the two heat exchangers. By controlling the opening and closing of the first and second openings of the three-way valve 34, the flow path of the working fluid in each heat exchanger is controlled, and the operation is stable and reliable.

[0141] like Figure 3 As shown, in some embodiments of the present invention, the air conditioner further includes a throttling device 33. The throttling device 33 is located upstream of the heat exchanger 15. The throttling device 33 is used to control the amount of working fluid entering the heat exchanger 15. The throttling device 33 generally includes a capillary tube, a mechanical expansion valve, an electronic expansion valve, or a solenoid valve, etc., preferably, the throttling device 33 is a solenoid valve.

[0142] like Figure 3 As shown, in some embodiments of the present invention, the air conditioner further includes a compressor 311, a condenser 36 connected in series, and a four-way valve 35 located between an electronic on / off valve 34 and the compressor 311. A throttling device is connected to the condenser 36. The compressor includes a receiver 312.

[0143] like Figure 4-12 As shown, in some embodiments of the present invention, each air outlet column 10 further includes a second air outlet 17 and a bypass ventilation duct. The second air outlet 17 is located on the front side of the air outlet column 10, and is on the side of the first air outlet 11 away from the other air outlet column 10. The bypass ventilation duct connects the second air outlet 17 and the air outlet duct. Both the first air outlet 11 and the second air outlet 17 extend along the length direction of the air outlet column 10.

[0144] like Figure 10 As shown, in some embodiments of the present invention, each air outlet column 10 has a first air guide surface 32 connected to the corresponding first air outlet 11 on one side away from the other air outlet column 10. The indoor unit of the air conditioner also includes two air guide devices 12, each air guide device 12 being respectively disposed at the corresponding first air outlet 11, for guiding air out in the width direction of the first air outlet 11 and movable to a wide-angle air guide position that defines a wide-angle air duct with the first air guide surface.

[0145] During operation, the air guide device 12 on the air outlet column 10 rotates to guide the direction of the air blown out from the first air outlet 11, specifically, such as Figure 9 As shown, when the air guide device 12 is rotated to the wide-angle air guide position, at least a portion of the air blown out from the first air outlet 11 enters the wide-angle air duct defined by the first air guide surface 32 and the air guide device 12, and blows out in a direction away from the other air outlet column 10, thereby expanding the air outlet angle of the first air outlet 11, and thus making the air outlet angle of the two air outlet columns 10 larger, thereby meeting the user's demand for wide-angle air supply from the air conditioner.

[0146] like Figure 4-13 As shown, in some embodiments of the present invention, each air outlet column includes an air outlet body and an air guide body 30. The front side of the air outlet body has a connecting opening extending along its length. Two edges extending along the length of the connecting opening are a first edge and a second edge, respectively. The surface of the air outlet body includes an air guide region connected to the first edge. The edge of the air guide region opposite to the first edge is a third edge. The air guide body 30 is disposed in front of the air guide region. The air guide body 30 includes a first air guide surface 32 disposed in front of the air guide body 30. The first air guide surface 32 has a fourth edge and a fifth edge, the fourth edge being close to the second edge, the fifth edge being close to the third edge, and the fifth edge being obliquely in front of the fourth edge. A bypass ventilation duct is formed between the air guide body 30 and the air guide region. The interval between the second edge and the end of the air guide body 30 having the fourth edge is a first air outlet 11, and the interval between the third edge and the end of the air guide body 30 having the fifth edge is a second air outlet 17. The bypass ventilation duct connects the connecting opening and the second air outlet 17.

[0147] In these implementations, by setting up the air outlet and the air guide, each air outlet column has two air outlets and a first air guide surface, thus achieving both wide-angle air outlet of the air conditioner and a novel design, achieving two goals at once.

[0148] In some embodiments of the present invention, such as Figure 4-12As shown, a micro-wind structure 18 is provided at the second air outlet 17. The micro-wind structure 18 causes the airflow passing through the second air outlet 17 to blow out towards the front side of the second air outlet 17 near the third edge. In other words, the air entering the bypass duct can also change its airflow direction and expand its airflow angle after passing through the micro-wind structure 18.

[0149] In some embodiments of the present invention, such as Figure 10-12 As shown, the breeze structure 18 includes a grille.

[0150] In some embodiments of the present invention, such as Figure 5-9 As shown, the micro-wind structure 18 includes multiple arc-shaped plates arranged in parallel. The multiple arc-shaped plates protrude in front of the first air outlet 11 so that the air passing through the arc-shaped plates blows out towards the front side of the second air outlet 17 near the third edge.

[0151] Of course, in other embodiments of the invention, the breeze structure 18 causes the airflow through the second air outlet 17 to blow out toward the front of the second air outlet 17.

[0152] In some embodiments of the present invention, such as Figure 10 As shown, an air intake structure 19 is provided at the inlet of the bypass ventilation duct to disperse the airflow passing through the inlet of the bypass ventilation duct.

[0153] Furthermore, in some embodiments of the present invention, such as Figure 10 As shown, the air inlet structure 19 is a microperforated plate, with its two edges along the length direction connected to the fourth edge and the first edge, respectively. A portion of the air outlet air is dispersed by the microperforations through the microperforated plate, becoming a gentle breeze, thus making the outlet air more "soft".

[0154] In some embodiments of the present invention, the micropores are arranged horizontally.

[0155] In some embodiments of the present invention, such as Figure 10 As shown, the air guide 30 also includes a second air guide surface 31 located behind the first air guide surface 32. The first air guide surface is an arc surface that arches away from the bypass ventilation duct. The second air guide surface 31 has a planar region connected to a fourth edge, with one end of the planar region away from the first edge located obliquely in front of the fourth edge. The fourth edge is located in front of the inlet of the bypass ventilation duct, meaning that the second air guide surface slopes obliquely forward from the front edge of the inlet of the bypass ventilation duct. Providing the second air guide surface 31 can reduce wind resistance and make it easier for the air entering the bypass ventilation duct through the air inlet structure 19 to pass through the micro-wind structure 18 and be blown out.

[0156] In some embodiments of the present invention, the micro-wind structure 18, the air inlet structure 19, and the air guide 30 are integrally formed.

[0157] In some embodiments of the present invention, such as Figure 9 As shown, the air guiding device 12 includes at least one air guiding plate. When the air guiding device moves to the wide-angle air guiding position, the edge of the air guiding plate closest to the air guiding body 30 is located in front of the first air guiding surface 32. This arrangement allows a wide-angle airflow channel to be formed between the air guiding plate closest to the air guiding body 30 and the first air guiding surface 32. Preferably, the air guiding device 12 includes two air guiding plates. The two air guiding plates are arranged along the width direction of the first air outlet 11.

[0158] In some embodiments of the present invention, such as Figure 4 As shown, the cross-section of the air duct wall connected to the first edge at the first edge is used as a reference cross-section. The air guide is located on the side of the reference cross-section away from the first air outlet. This arrangement is beneficial for wide-angle air guidance without obstructing the air outlet.

[0159] In some embodiments of the present invention, the air intake interval 20 comprises only an inlet section and an outlet section that are connected to each other. The width of the outlet section gradually increases along the direction of airflow. The width of the inlet section gradually decreases along the direction of airflow. The above-described arrangement of the air intake interval 20 facilitates the entry of air behind the air intake interval 20 and also facilitates the forward flow of air within the air intake interval 20.

[0160] In some embodiments of the present invention, such as Figure 4 As shown, the second edge is located on the front side of the air outlet section.

[0161] In some embodiments of the present invention, such as Figure 4 As shown, the first edge is in front of the second edge.

[0162] In some embodiments of the present invention, such as Figure 4 As shown, the fourth edge is located diagonally in front of the corresponding second edge.

[0163] In some embodiments of the present invention, the first air guide surface 32 is arc-shaped, which is more conducive to wide-angle air delivery.

[0164] In some embodiments of the present invention, the air outlet column 10 includes a vertical plane extending in the lateral direction connected to the front edge of the first air guide surface 32, the vertical plane being the front end of the air outlet column 10, and the second air outlet 17 being disposed on the vertical plane.

[0165] In some embodiments of the invention, the inner surface of the air guide plate directs the airflow away from the other air outlet column 10. This arrangement also helps to increase the air outlet angle of the first air outlet 11.

[0166] In some embodiments of the present invention, the first air guide plate is close to the second edge. The first air guide plate and the second air guide plate are movable to a preset position. The angle between the front end cross-section of the inner surface of the first air guide plate and the vertical reference plane is a first angle. The angle between the front end cross-section of the inner surface of the second air guide plate and the vertical reference plane is a second angle. At the preset position, the first angle is smaller than the second angle, and the second angle is greater than 60°.

[0167] In some embodiments of the present invention, the air guiding device 12 includes a plurality of air guiding plates, each with a curved front surface. When the first air outlet 11 is closed, the second edge and the front surface of each air guiding plate are on the same curved surface. This arrangement makes the indoor unit of the air conditioner look harmonious and aesthetically pleasing.

[0168] In some embodiments of the present invention, each air outlet has an air inlet 16 communicating with a connecting port on its side wall. Each air outlet is equipped with a fan that guides air into the air outlet and blows it out from the connecting port. The fan is a cross-flow fan 14. At least one air outlet is equipped with a heat exchanger 15. When one of the two air outlets blows heat exchange airflow, the heat exchange airflow, non-heat exchange airflow, and air within the induced draft interval 20 mix in front of the vertical air conditioner indoor unit, resulting in a mixed airflow temperature closer to room temperature and thus a gentler airflow. When both air outlets blow heat exchange airflow, the heat exchange airflow and air within the induced draft interval 20 mix in front of the vertical air conditioner indoor unit, similarly resulting in a gentler airflow.

[0169] In some embodiments of the present invention, the air conditioner has multiple air outlet modes. For example... Figure 4 and Figure 13 As shown, the air guide device 12 closes the first air outlet 11. The air passing through the connecting port enters the bypass ventilation duct through the air inlet structure 19 and is blown out from the second air outlet 17 through the micro-wind structure 18. This air supply mode can be called the comfort air supply mode, also known as the micro-wind mode. Figure 6 and Figure 11 As shown, the air guide device 12 extends in the front-to-back direction. At this time, the opening area of ​​the first air outlet 11 is at its maximum. The air outlets 11 of the two first air outlets drive the air within the air-guiding interval 20 to flow forward, resulting in the maximum air volume. This air outlet mode can be called the maximum air volume mode. Figure 7 As shown, the two first air outlets 11 direct airflow towards each other. The airflow from the two first air outlets 11 drives the air within the air intake interval 20 to flow forward, resulting in a greater wind speed after mixing, which helps to deliver air over long distances. This air delivery mode can be called a long-distance air delivery mode. Figure 8 and Figure 12As shown, both air guide plates of the air guiding device 12 are inclined towards the air guiding body 30, and the air outlets of the two first air outlets 11 are directed away from each other, so that the air outlets of the two first air outlets 11 are mainly directed to the sides. This air outlet mode can be called a wide-angle wraparound air mode. Figure 9 As shown, the air guide plate near the second edge of the two air guide plates of the air guide device 12 extends back and forth, and the air guide plate near the air guide body 30 forms a wide-angle air duct with the first air guide surface 32, so that the air outlet angle through the first air outlet 11 is relatively large. This air outlet mode can be called a wide-area uniform airflow mode (also called: wide-angle air supply mode). Figure 5 As shown, one of the air guide devices is closed, while the other guides the air; this air supply mode can be called a single-unit air supply mode. Alternatively, one air guide device can guide the air, while the heat exchanger in the other air supply column is closed, and the air inlet of the other air supply column is connected to the indoor or outdoor environment. That is, one air supply column supplies heat-exchange air, while the other supplies non-heat-exchange indoor air or fresh air; this air supply mode can be called a healthy air supply mode.

[0170] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
