Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning centralized control, and in particular to a centralized control system. Background Art

[0002] In the prior art, in order to increase the air supply range of the air conditioner, a rotatable air guide plate is provided at the air outlet. The air guide plate is a wind direction adjusting component in the air conditioner. The direction of the air guide plate is generally controlled by the rotation of a servo. Due to the installation position of the air conditioner and the control method of the servo, the user is unable or not allowed to manually swing the air guide plate. The user uses a remote control, a wire controller, an APP or other non-contact manual method to remotely control the air guide plate to swing in the horizontal direction or in the vertical direction.

[0003] However, when the user adjusts the air guide plate, the user can only operate but cannot feel the adjustment status of the air guide plate, and the user perception effect is not good. Summary of the invention

[0004] The present invention provides a centralized control system, which can adjust the gear position of the air guide plate by touch on the centralized control screen and also display a picture of the air guide plate corresponding to the adjusted gear position of the air guide plate, so as to intuitively show the current adjustment status of the air guide plate to the user, and through touch adjustment and instant feedback, the user participation and perception are good, thereby improving the user experience.

[0016] While adjusting the position of the button, the wind deflector image corresponding to the position of the button is linked and displayed on the centralized control screen;

[0017] Determining the gear position of the air guide plate of the indoor unit based on the position of the button;

[0018] A first air deflector gear position adjustment instruction corresponding to the determined gear position is issued to adjust the gear position of the air deflector.

[0019] The centralized control system provided in the present application can select the air deflector picture set corresponding to the indoor unit through the air deflector picture set corresponding to the indoor unit stored on the centralized control screen, according to the air deflector air outlet type and the number of air deflector gears uploaded by the indoor unit and received by the centralized control screen, configure a slider control on the centralized controller, change the air deflector gear by operating the buttons on the slider control and display the air deflector picture corresponding to the air deflector gear on the centralized control screen at the same time, so that the user can intuitively see the air deflector picture representing the adjustment status of the air deflector while operating the air deflector gear, thereby improving the user's perception of adjusting the air deflector, and through touch adjustment and instant feedback, the user has a high sense of participation, thereby improving the user experience.

[0020] In some embodiments of the present application, when the slider control is adjusted, the position of the button can be known, and at the same time, when the initial value of the front end position of the slider and the end value of the end position are known, the current value of the button at any position can be obtained, which is convenient for characterizing the wind deflector gear.

[0040] Based on the adjusted position of the button, the progress position of the progress bar control is obtained, and the remaining progress is displayed.

[0041] In some embodiments of the present application, when the slider control is adjusted, the position of the button can be known, and at the same time, when the initial value of the starting position of the slider and the end value of the end position are known, the current value of the button at any position can be obtained, which is convenient for characterizing the gear position of the air guide plate and displaying the remaining progress at the same time.

[0042] The centralized control screen is also configured as:

[0043] When adjusting the position of the key, an adjustment value is obtained based on the distance and relative direction between the current position of the key and its initial position, wherein the initial position of the key corresponds to an initial value;

[0069] The centralized control system is used for centralized control of multi-split central air conditioners, and can realize local and remote control. If it is used for remote control and remote data upload, it is necessary to connect to the Internet through the communication unit and log in to the centralized control system for operation.

[0070] A multi-split central air conditioner includes multiple indoor units and outdoor units.

[0071] In terms of communication, multiple indoor units and outdoor units are connected to a communication bus, and in terms of pipeline connection, multiple indoor units are connected to the outdoor unit through refrigerant pipelines.

[0072] The unit formed by the outdoor unit and the indoor unit can be called an air-conditioning unit.

[0073] As follows, the basic working principle of the air conditioning unit will be described.

[0074] [Basic working principle of air conditioning unit]

[0075] The air conditioning unit performs the cooling and heating cycle of the air conditioning unit by using a compressor, condenser, expansion valve and evaporator. The cooling and heating cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0076] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0077] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioning unit can adjust the temperature of the indoor space.

[0078] The outdoor unit of an air conditioning unit refers to the part of the refrigeration cycle including the compressor, outdoor heat exchanger and outdoor fan, the indoor unit of the air conditioning unit includes the indoor heat exchanger and indoor fan, and a throttling device (such as a capillary tube or an electronic expansion valve) may be provided in the indoor unit or the outdoor unit.

[0079] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner performs a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner performs a cooling mode.

[0080] Among them, the indoor heat exchanger and the outdoor heat exchanger are converted to serve as a condenser or an evaporator, generally using a four-way valve. For specific reference, refer to the settings of conventional air-conditioning units and will not be elaborated here.

[0081] The refrigeration working principle of the air-conditioning unit is: the operation of the compressor makes the indoor heat exchanger (in the indoor unit, it is the evaporator at this time) in an ultra-low pressure state, the liquid refrigerant in the indoor heat exchanger evaporates rapidly to absorb heat, and the wind blown out by the indoor fan is cooled by the indoor heat exchanger coil and becomes cold air blown into the room. The evaporated refrigerant is pressurized by the compressor and condensed into liquid under the high-pressure environment of the outdoor heat exchanger (in the outdoor unit, it is the condenser at this time), releasing heat, and dissipating the heat into the atmosphere through the outdoor fan. This cycle achieves the cooling effect.

[0082] The heating working principle of the air conditioning unit is as follows: the gaseous refrigerant is pressurized by the compressor, becomes a high-temperature and high-pressure gas, enters the indoor heat exchanger (the condenser at this time), condenses and liquefies to release heat, becomes a liquid, and heats the indoor air at the same time, thereby achieving the purpose of increasing the indoor temperature. The liquid refrigerant is decompressed by the throttling device and enters the outdoor heat exchanger (the evaporator at this time), evaporates and absorbs heat to become a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder), becomes a gaseous refrigerant, and enters the compressor again to start the next cycle.

[0083] The multi-split central air conditioner is connected to the centralized control panel 10 via a communication bus to achieve centralized control of the centralized control panel 10 .

[0084] The present application relates to the gear position control of the air guide plate in the indoor unit, and therefore, the structure of the indoor unit is first described as follows.

[0085] [Structure of indoor unit]

[0086] The indoor unit includes, in addition to the indoor heat exchanger and the indoor fan described above, a casing and a plurality of air guide plates for air guide control.

[0087] The indoor unit involved in the present application is an indoor unit with multi-directional air outlet, so a plurality of air outlets and a plurality of air inlets are arranged on the shell.

[0088] By driving the indoor fan, indoor air near the air inlet is taken into the interior of the casing through the air inlet.

[0089] The air outlet is connected to the interior of the casing through a vortex flow path that continues from the indoor fan.

[0090] The indoor air sucked in from the air inlet undergoes heat exchange in the indoor heat exchanger and is then blown out from the air outlet into the room through the vortex flow path.

[0091] At least one horizontal air guide plate extending long in the left-right direction is provided at the air outlet.

[0092] The horizontal air guide plates are rotatably mounted on the housing. The horizontal air guide plates are configured to be independently rotatable around respective rotation centers extending to the left and right by means of horizontal air guide plate driving motors provided for each horizontal air guide plate. Furthermore, the horizontal air guide plates adjust the wind direction of the air blown out from the air outlet in the vertical direction individually or in cooperation with each other.

[0093] In this way, the horizontal wind guide plate is used to swing up and down to achieve up and down swinging wind.

[0094] A plurality of vertical air guide plates having a plane intersecting the left-right direction are provided deep in the air outlet.

[0095] The vertical air guide plates can be rotated left and right around a rotation center extending in the up-down direction (a direction intersecting the left-right direction) by a vertical air guide plate driving motor. These multiple vertical air guide plates adjust the wind direction of the air blown out from the air outlet left and right.

[0096] In this way, the vertical wind guide plate is swung left and right to achieve left and right wind swing.

[0097] The user can manually adjust the position of the vertical air guide plate and the horizontal air guide plate by using the wind direction setting switch of the remote controller. The indoor unit can set the wind direction such as "front blowing", "right blowing" and "left blowing" in the left and right directions. For example, selecting the wind direction of "front blowing" means that the vertical air guide plate stops at a position extending in the front-to-back direction and blows conditioned air toward the front.

[0098] When the wind direction of "right blowing" is selected, the vertical wind guide plate stops at a position tilted to the right, and the conditioned air is blown to the right. When the wind direction of "left blowing" is selected, the vertical wind guide plate stops at a position tilted to the left, and the conditioned air is blown to the left.

[0099] In addition, the indoor unit is configured to be able to select, in the up-down direction, wind directions such as “ceiling airflow”, “upward blowing”, “downward blowing”, and “vertical airflow”.

[0100] When the wind direction of "ceiling airflow" is selected, the indoor unit makes the end of the horizontal air guide plate face the uppermost part, blows out conditioned air from the air outlet, and makes the conditioned air flow along the ceiling. When the wind direction of "upward blowing" is selected, the indoor unit makes the end of the horizontal air guide plate slightly lower than the position of the wind direction of "ceiling airflow", and blows out conditioned air in a direction upward than the horizontal direction. When the wind direction of "downward blowing" is selected, the indoor unit blows out conditioned air downward than the horizontal direction. When the wind direction of "vertical airflow" is selected, the indoor unit makes the end of the horizontal air guide plate face the lowermost part, and blows out conditioned air, and makes the conditioned air flow in a vertical downward direction.

[0101] The wind direction setting switch of the remote controller can be used to select the state in which the vertical wind guide plate swings. In addition, the wind direction setting switch of the remote controller can be used to select the state in which the horizontal wind guide plate swings. In addition, the state in which both the vertical wind guide plate and the horizontal wind guide plate swing can be selected.

[0102] As described above, the position of the vertical air guide plate and / or the horizontal air guide plate can also be adjusted using the remote controller.

[0103] [Air guide plate outlet type]

[0104] The present application relates to the gear position control of the air guide plate in the indoor unit based on the centralized control panel 10, and the air guide plate may refer to a horizontal air guide plate or a vertical air guide plate.

[0105] For each air outlet, there are multiple air guide plates, and the multiple air guide plates include at least one horizontal air guide plate and multiple vertical air guide plates.

[0106] The models of indoor units involved in the present application include four-direction models and two-direction models. Of course, they may also include three-direction models and single-direction models of ordinary wall-mounted indoor units.

[0107] The four-direction model includes four air outlets, and at each air outlet there is at least one horizontal air guide plate and multiple vertical air guide plates.

[0108] The three-direction model includes three air outlets, and at least one horizontal air guide plate and multiple vertical air guide plates are arranged at each air outlet.

[0109] The two-direction model includes two air outlets, and at least one horizontal air guide plate and multiple vertical air guide plates are arranged at each air outlet.

[0110] The unidirectional model includes an air outlet, at which at least one horizontal air guide plate and a plurality of vertical air guide plates are arranged.

[0111] When controlling the air guide plates of the indoor unit, multiple air guide plates at an air outlet can be designed to swing up and down (i.e., multiple horizontal air guide plates swing up and down), swing left and right (i.e., multiple vertical air guide plates swing left and right), or both swing up and down and swing left and right.

[0112] In some embodiments of the present application, a four-direction model and a two-direction model are involved.

[0113] The following uses examples to illustrate the air outlet types of air guide plates of different models.

[0114] Among them, the four-direction model involves: (1) four-outlet, that is, air is discharged from all four outlets (denoted as: unified control), and (2) two-outlet, that is, air is discharged from both outlets.

[0115] For example, (21) the two air outlets are front and rear side air outlets (recorded as: front and rear air guide plate control), including: (211) up and down swinging of multiple air guide plates at the front and rear side air outlets (recorded as: front and rear air guide plate control-up and down swinging); (212) left and right swinging of multiple air guide plates at the front and rear side air outlets (recorded as: front and rear air guide plate control-left and right swinging).

[0116] For example, (22) the two air outlets are left and right air outlets (recorded as: left and right air guide plate control), including: (221) up and down swinging of multiple air guide plates at the left and right air outlets (recorded as: left and right air guide plate control-up and down swinging); (222) left and right swinging of multiple air guide plates at the left and right air outlets (recorded as: left and right air guide plate control-left and right swinging).

[0117] It should be noted that the "unified control" mentioned above means that the air guide plates at the four air outlets are controlled according to a preset program. For example, the horizontal air guide plates at the four air outlets all swing up and down, or the vertical air guide plates at the four air outlets all swing left and right.

[0118] Two-way models involve: (1) two-way air outlets, that is, air is discharged from both air outlets; (2) single-way air outlet, that is, air is discharged from a single air outlet.

[0119] For example, (11) the two air outlets are front and rear side air outlets (denoted as: front and rear air guide plate control), including: (111) up and down swinging of multiple air guide plates at the air outlets of the front and rear side air outlets (denoted as: front and rear air guide plate control-up and down swinging); (112) left and right swinging of multiple air guide plates at the front and rear side air outlets (denoted as: front and rear air guide plate control-left and right swinging).

[0120] For example, (12) the two air outlets are left and right air outlets (recorded as: left and right air guide plate control), including: (121) up and down swinging of multiple air guide plates at the left and right air outlets (recorded as: left and right air guide plate control-up and down swinging); (122) left and right swinging of multiple air guide plates at the left and right air outlets (recorded as: left and right air guide plate control-left and right swinging).

[0121] For example, (21) the single air outlet is the front air outlet (denoted as: front air guide plate control), including: (211) the up and down swinging of multiple air guide plates at the front air outlet (denoted as: front air guide plate control-up and down swinging); (212) the left and right swinging of multiple air guide plates at the front air outlet (denoted as: front air guide plate control-left and right swinging).

[0122] Furthermore, when the air guide plate swings, it has an air guide plate gear position, which corresponds to each wind speed gear position of the air guide plate driving motor and is used to adjust the wind speed at the air outlet corresponding to the air guide plate.

[0123] When the gear is high, the wind speed is high, and when the gear is low, the wind speed is low.

[0124] Therefore, when the present application involves the gear position control of the air guide plate (horizontal air guide plate or vertical air guide plate) corresponding to each air outlet, it also involves the number of air guide plate gear positions corresponding to the air guide plate.

[0125] In some embodiments of the present application, in order to realize the adjustment of the gear position control of the air guide plate based on the centralized control screen, and also display a picture of the air guide plate showing the adjustment status of the adjusted air guide plate on the centralized control screen, it is also necessary to establish a set of air guide plate pictures corresponding to the number of air guide plate gear positions for each air guide plate control under the above-mentioned air outlet type.

[0126] Based on actual control requirements, design the air outlet type of the air guide plate of each indoor unit, the corresponding number of air guide plate positions, and the corresponding air guide plate picture set.

[0127] The following is an example.

[0128] (A) For example, in the "unified control" of the four air outlets, the horizontal air guide plates at the four air outlets all swing up and down, and the number of air guide plate gears of the horizontal air guide plates is 7 gears, namely 1 to 7, from low gear to high gear, and the corresponding wind speed increases successively.

[0129] Thus, in this case, a corresponding set of air guide plate images is 7 air guide plate images corresponding to gears 1 to 7 respectively.

[0130] (B) For example, for the "front and rear air guide plate control - up and down swing" in the two air outlets of the four-directional model, the horizontal air guide plates at the front and rear air outlets swing up and down, and the number of air guide plate gears of the horizontal air guide plates is 8 gears, namely 1 to 8, from low gear to high gear, and the corresponding wind speed increases successively.

[0131] Thus, in this case, a corresponding set of air guide plate images is 8 air guide plate images corresponding to gears 1 to 8 respectively.

[0132] (C) For example, for the "front and rear air guide plate control - left and right swing" in the two-way air outlet of the two-way model, the vertical air guide plates at the front and rear air outlets swing left and right, and the number of air guide plate gears of the vertical air guide plates is 8 gears, i.e. 1 to 8, from low gear to high gear, and the corresponding wind speed increases successively.

[0133] Thus, in this case, a corresponding set of air guide plate images is 8 air guide plate images corresponding to gears 1 to 8 respectively.

[0134] (D) For example, for the "front and rear air guide plate control - up and down swing" in the two air outlets of the two-way model, the horizontal air guide plates at the front and rear air outlets swing up and down, and the number of air guide plate gears of the horizontal air guide plates is 8 gears, namely 1 to 8, from low gear to high gear, and the corresponding wind speed increases successively.

[0135] Thus, in this case, a corresponding set of air guide plate images is 8 air guide plate images corresponding to gears 1 to 8 respectively.

[0136] In addition, examples are given here of the number of air deflector positions and the air deflector picture set that can correspond to different air deflector outlet types, but are not limited to the examples described above.

[0137] As described above, in order to implement air deflector control based on the centralized control panel 10, an air deflector picture set corresponding to the air deflector outlet type of the indoor unit is pre-stored in the centralized control panel 10, for example, stored in a storage unit.

[0138] See also Figure 2When the multi-split central air conditioner communicates with the centralized control panel 10, the air outlet type of the air guide plate and the corresponding number of air guide plate gears will be reported to the centralized control panel 10. In this way, after receiving the reported information, the centralized control panel 10 will call the corresponding air guide plate picture set from the storage unit.

[0139] In order to effectively utilize the storage resources in the centralized control screen 10, when the air outlet types of the air guide plates and the number of air guide plate gears involved in (B) and (D) as described above are the same, the same set of air guide plate picture sets can be used.

[0140] As described above, for an indoor unit, at least one air guide plate air outlet type can be set. Thus, the number of air guide plate gears corresponding to the air guide plate air outlet type and the corresponding air guide plate picture set can also be set.

[0141] [Air deflector position control based on centralized control panel]

[0142] As described above, according to actual control requirements, the air guide plate outlet type of the indoor unit, the corresponding number of air guide plate gears, and the corresponding air guide plate picture set have been set, wherein the number of air guide plate gears is the same as the number of corresponding air guide plate picture sets.

[0143] As described above, the air guide plate picture sets corresponding to the air guide plate outlet types of all indoor units connected to the centralized control panel 10 are pre-stored on the centralized control panel, so that multiple groups of air guide plate picture sets are stored on the centralized control panel.

[0144] As follows, you can refer to Figures 1 to 4 Describe the control of the air guide plate position of the indoor unit through the centralized control panel.

[0145] S1: Based on the air outlet type of the air guide plate of the indoor unit and the number of air guide plate gears received by the centralized control panel 10, a corresponding set of air guide plate picture sets is selected.

[0146] As described above, since the multi-split central air conditioner and the centralized control panel 10 are connected to the same communication bus, when the multi-split central air conditioner communicates with the centralized control panel 10 wirelessly or wired, the centralized control panel 10 can receive the air outlet type of the air guide plate and the number of air guide plate gears reported by the indoor unit. In this way, a corresponding set of air guide plate picture sets can be selected from multiple sets of air guide plate picture sets.

[0147] For example, if the air guide plate outlet type of the indoor unit is "front and rear air guide plate control - up and down swing)" under four air outlets and the number of air guide plate gears is 7, then a set of air guide plate picture sets corresponding to "front and rear air guide plate control - up and down swing" can be selected on the centralized control screen 10, and there are 7 air guide plate pictures in the air guide plate picture set.

[0148] It should be noted that when the air guide plates at multiple air outlets are controlled simultaneously, the control of the air guide plates at each air outlet is the same.

[0149] For example, in "front and rear air guide plate control - up and down swinging", multiple horizontal air guide plates at the front air outlet swing up and down, and at the same time, multiple horizontal air guide plates at the rear air outlet swing up and down.

[0150] As follows, see Figure 3 and Figure 4 , the adjustment of the air guide plate gear position using the slider control displayed on the centralized control screen 10 will be described.

[0151] S2: Control the touch area of ​​the centralized control screen 10 (see Figures 3 to 9 ) on the display area in the .

[0152] The button 20 in the above slider control may have various forms, such as a circle, a square, a triangle or various icons.

[0153] In some embodiments of the present application, the button 20 in the slider control has a head position and an end position to respectively correspond to the lowest gear position and the highest gear position of the air guide plate.

[0154] In order to simultaneously operate the button 20 in the slider space, the position of the button 20 reflects the corresponding wind deflector gear position. Therefore, the position between the head end position and the end end position is equally divided into multiple positions to form multiple continuous positions in the direction from the head end position to the end end position.

[0155] The multiple continuous positions correspond to multiple continuous gears of the air guide plate from a low gear to a high gear, and also correspond to multiple air guide plate pictures in a set of air guide plate pictures selected in S1.

[0156] The button 20 in the slider control can be used to drag in the horizontal direction or in the vertical direction.

[0157] See also Figure 3 and Figure 4 Taking the button 20 in the slider control for dragging in the vertical direction as an example, when the button 20 in the slider control is dragged, the position of the button 20 is identified.

[0158] For example, the air guide plate needs to be controlled in seven gears, namely, the first gear, the second gear, the third gear, the fourth gear, the fifth gear, the sixth gear and the seventh gear in ascending order.

[0159] The number of multiple consecutive positions of the recognized keys should also be 7, namely (x1, y1), (x1, y2), (x1, y3), (x1, y4), (x1, y5), (x1, y6) and (x1, y7).

[0160] There are also 7 wind guide plate images in the set of wind guide plate images selected in S1, which correspond to the first wind guide plate image, the second wind guide plate image, the third wind guide plate image, the fourth wind guide plate image, the fifth wind guide plate image, the sixth wind guide plate image and the seventh wind guide plate image of (x1, y1), (x1, y2), (x1, y3), (x1, y4), (x1, y5), (x1, y6) and (x1, y7) respectively.

[0161] The first gear corresponds to (x1, y1) and the first air guide plate image; the second gear corresponds to (x1, y2) and the second air guide plate image; the third gear corresponds to (x1, y3) and the third air guide plate image; the fourth gear corresponds to (x1, y4) and the fourth air guide plate image; the fifth gear corresponds to (x1, y5) and the fifth air guide plate image; the sixth gear corresponds to (x1, y6) and the sixth air guide plate image; and the seventh gear corresponds to (x1, y7) and the seventh air guide plate image.

[0162] In some embodiments of the present application, a head value corresponding to the head position of the key 20 and a tail value corresponding to the tail position of the key 20 are also set.

[0163] The value at the first end corresponds to the lowest gear of the air guide plate, and the value at the last end corresponds to the highest gear of the air guide plate.

[0164] Each position of the button 20 corresponds to a numerical value to represent the wind deflector gear corresponding to the current position of the button 20 .

[0165] For example, the first value is 1 and the last value is 7.

[0166] The value 1, the first gear, (x1, y1), and the picture of the first air guide plate correspond one to one; the value 2, the second gear, (x1, y2), and the picture of the second air guide plate correspond one to one; the value 3, the third gear, (x1, y3), and the picture of the third air guide plate correspond one to one; the value 4, the fourth gear, (x1, y4), and the picture of the fourth air guide plate correspond one to one; the value 5, the fifth gear, (x1, y5), and the picture of the fifth air guide plate correspond one to one; the value 6, the sixth gear, (x1, y6), and the picture of the sixth air guide plate correspond one to one; the value 7, the seventh gear, (x1, y7), and the picture of the seventh air guide plate correspond one to one.

[0167] S3: Detecting the operation of the button 20.

[0168] The user can perform, for example, a simple drag operation, a simple press operation, or a press operation while dragging on the button 20 in the slider control.

[0169] First, the finger needs to touch the touch screen, that is, a starting action is generated. After the starting action is detected on the button 20 in the slider control, the position of the finger (that is, the button 20) is obtained.

[0170] S4: Based on the operation on the key 20, the position of the key 20 is adjusted.

[0171] In some embodiments of the present application, the button 20 in the slider control can move following the dragging of the user's finger.

[0172] Taking the button 20 in the above-mentioned slider control for dragging in the vertical direction as an example, when the position of the button 20 is adjusted, and while the position of the button 20 is adjusted, the current position of the button 20 can be obtained, for example, the coordinates of the current position of the button 20 are (x1, y4).

[0173] S5: While adjusting the position of the button 20 , the wind deflector image P corresponding to the position of the button 20 is linked and displayed on the centralized control screen 10 .

[0174] As described above, when the position of the button 20 is adjusted, the position of the button 20 corresponds one-to-one with the air deflector picture in the selected air deflector picture set.

[0175] See also Figure 4 Therefore, when the corresponding position of the button 20 is adjusted, for example (x1, y2), the integrated control screen 10 will also switch to display the second air guide plate picture P corresponding to the corresponding second gear.

[0176] When the button 20 is dragged in the vertical direction, the order of the air guide plate pictures in the corresponding group of air guide plate picture sets is changed on the touch screen of the integrated control screen 10, and the air guide plate pictures P corresponding to the positions of the buttons 20 (i.e., the air guide plate gears) are switched out in turn. The speed of dragging will also affect the switching speed of the air guide plate picture set.

[0177] In this way, based on the integrated control screen 10, the user can intuitively reflect the adjustment status of the air guide plate by touch adjustment, which has strong user perception and participation and improves the user experience.

[0178] As mentioned above, see Figure 4 In order to display the air guide plate position of the corresponding air guide plate (for example, the second position "2" shown in S5) when operating the button 20, so that the user can not only intuitively see the air guide plate adjustment status during touch operation, but also intuitively display the adjusted air guide plate position, it is necessary to calculate the value corresponding to the position of the button 20.

[0179] In some embodiments of the present application, the following calculation method is used.

[0180] (1) When adjusting the position of the key 20, an adjustment value d is obtained based on the distance and relative direction between the current position of the key 20 and its initial position.

[0181] The initial position corresponds to an initial value, the head position of the key 20 corresponds to a head value, and the end position of the key 20 corresponds to an end value.

[0182] For example, the starting value corresponding to the starting position (x1, y1) is a, and the ending value corresponding to the ending position (x1, y7) is b.

[0183] If the initial value is c, and the coordinates of the initial position of the key 20 are (x1, y3), then y3 may be, for example, (y7-y1)*(ca) / (ba).

[0184] However, in some embodiments of the present application, the corresponding relationship between the position of the key 20 and the value can also be specifically set according to needs.

[0185] For example, the coordinates of the current position of button 20 in the slider control are (x1, y4), and the distance between it and the initial position (x1, y3) is |y4-y3|. Therefore, the size of the adjustment value d can be obtained as |y4-y3|(ba) / (y7-y1).

[0186] According to the direction of the button 20 in the slider control relative to its initial position, it can be determined whether the user wants to increase or decrease the initial value; for example, if the user drags the button 20 in the slider control upward, it can be known that the adjustment value is +d.

[0187] It should be noted that in some embodiments of the present application, the number of air guide plate gears received by the integrated control panel 10 is different. Therefore, the starting value and the ending value of the button 20 in the slider control will be dynamically assigned so that the starting value corresponds to the lowest wind speed and the ending value corresponds to the highest air duct.

[0188] (2) The initial value is adjusted using the adjustment value d to obtain a value corresponding to the position of the button 20 . The obtained value is consistent with the gear position of the air guide plate corresponding to the position of the button 20 .

[0189] For example, when the adjustment value is +d as described above, the value of the acquired position of the key 20 (ie, (x1, y2)) is c+d.

[0190] At this time, c+d is consistent with the gear position of the air guide plate corresponding to the position (x1, y2), for example, the second gear position (number "2"), see Figure 4 .

[0191] (3) While the air deflector image P corresponding to the position of the button 20 is updated and displayed on the centralized control screen 10 , the acquired numerical value corresponding to the position of the button 20 is displayed.

[0192] For example, see Figure 4 When the button 20 is dragged to display the value "2", the second air guide plate picture P corresponding to the second gear is displayed on the centralized control screen 10, and both are performed simultaneously.

[0193] In some embodiments of the present application, the obtained value corresponding to the position of the key 20 is displayed, specifically, the obtained value corresponding to the position of the key 20 is controlled to be displayed on the key in the form of text, see Figure 3 and Figure 4 .

[0194] For example, as mentioned above, see Figure 4 The text “2” is displayed on the button 20 to inform the user that the current position of the button 20 corresponds to the second wind speed.

[0195] In some embodiments of the present application, the acquired numerical value corresponding to the position of the button 20 is displayed. Specifically, the acquired numerical value corresponding to the position of the button 20 may be controlled to be displayed in a preset direction of the slider control, and the displayed numerical value is controlled to move with the button 20.

[0196] The value "2" can be controlled to be displayed in a preset direction of the slider control, for example, the value "2" is displayed above or on the left side of the slider control, and so on.

[0197] In addition, in some embodiments of the present application, the displayed value "2" can be controlled to move along with the slider control, thereby facilitating user observation.

[0198] However, it should be noted that, in some embodiments of the present application, the value "2" may also be displayed in a fixed area, and this is not specifically limited in the present application.

[0199] S6: Based on the position of the button 20, the gear position of the air guide plate of the indoor unit is determined.

[0200] As described above, the position of the button 20 and the wind deflector position of the wind deflector correspond to each other.

[0201] Therefore, based on the position (x1, y2) in S5, the gear position of the corresponding air guide plate is obtained, that is, the second gear position.

[0202] S7: issuing a first air guide plate gear position adjustment instruction corresponding to the determined gear position to adjust the gear position of the air guide plate.

[0203] See also Figure 2The centralized control panel 10 and the indoor unit are connected to the same communication bus. Therefore, when it is determined that the position of the button 20 is adjusted to the position (x1, y2), that is, the gear is adjusted to the second gear.

[0204] In this way, the centralized control panel 10 sends the first air guide plate gear position adjustment instruction to the corresponding indoor unit, such as the control unit in the indoor unit, via wired / wireless means.

[0205] The control unit sends a driving signal to the air guide plate driving motor to adjust the second gear position of the air guide plate.

[0206] See also Figures 5 to 7 In order to improve the user's touch perception level and touch convenience on the centralized control screen 10, the centralized control screen 10 is also configured to: control the entire touch screen of the centralized control screen 10 to display the button 20' in the sliding control, so that the trigger area of ​​the button 20' in the slider control covers the entire touch screen of the centralized control screen 10.

[0207] In some embodiments of the present application, in order to clearly show the key 20' in the entire touch screen, see Figures 5 to 7 The button 20' is represented by a rectangular frame, and in actual use, the user cannot see the rectangular frame.

[0208] Among them, the sliding control is set to be invisible to avoid blocking the air guide plate image P that is linked updated and displayed on the integrated control screen 10.

[0209] In order to enhance the perception of the gear position of the air deflector, the corresponding gear number will be displayed simultaneously when the button 20 ′ is dragged to prompt the user.

[0210] The slider control as described above is located in the upper layer of the wind deflector image set.

[0211] See also Figures 5 to 7 When adjusting the button 20' respectively, the position of the button 20' dragged, the corresponding wind deflector gear position T and the corresponding wind deflector picture P are displayed.

[0212] See also Figure 8 and Fig. 9 Furthermore, for the air deflector control with the same air deflector outlet type and the same number of air deflector gear positions, a linked first sliding control and a second sliding control may be set.

[0213] For example, the linkage setting may be performed in a data transmission manner. For example, after the button 20 in the first sliding control recognizes the data of its own position, it transmits the data to the button 20' in the second sliding control.

[0214] The controls of the first sliding control and the second sliding control are the same as described above.

[0215] See also Figure 8 and Fig. 9 The difference between the first sliding control and the second sliding control is that the first sliding control can be set on one side of the integrated control screen 10, for example, the rightmost side, wherein the trigger area of ​​the first sliding control is the right part of the touch screen, and is not set to a transparent color (i.e., visible); the trigger area of ​​the second sliding control is the entire touch screen, and is set to a transparent color (i.e., invisible), wherein the rectangular box is shown only for the convenience of description of this application.

[0216] In this way, the button 20 of the first sliding control and the button 20 ′ of the second sliding control can be operated at the same time.

[0217] See also Figures 3 to 9 In order to show the user the remaining progress of not adjusting the air guide plate gear position, in some embodiments of the present application, the centralized control screen 10 is also configured to perform the following.

[0218] (1) Controlling the display of a progress bar control 30 on the touch area of ​​the centralized control screen 10, wherein the progress bar control 30 is located at the lower layer of the slider control, and the progress bar control 30 has a plurality of progress positions corresponding to a plurality of continuous positions of the button 20 / 20';

[0219] For example, as described above, when the button 20 / 20' has a plurality of consecutive positions (x1, y1), (x1, y2), (x1, y3), (x1, y4), (x1, y5), (x1, y6) and (x1, y7), the correspondingly arranged progress bar control 30 also has positions (x1', y1'), (x1', y2'), (x1', y3'), (x1', y4'), (x1', y5'), (x1', y6') and (x1', y7') corresponding to the positions respectively.

[0220] (2) Based on the adjusted position of the button 20 / 20 ′, the progress position of the progress bar control 30 is obtained, and the remaining progress is displayed.

[0221] As described above, if the position of the adjusted button 20 / 20' is at (x1, y4), the current position (x1', y4') of the progress bar control 30 can be obtained, so that the remaining progress can be displayed.

[0222] Of course, the value corresponding to the progress bar control 30 may also be set based on the value corresponding to the position of the button 20 / 20 ′, which is not limited here.

[0223] In some embodiments of the present application, when there are a slider control, a progress bar control 30 and a set of pictures of air deflectors, the slider control, the progress bar control 30 and the set of pictures of air deflectors are designed in sequence up and down.

[0224] For example, as described above, when the first sliding control is set on one side of the centralized control screen 10, except that the triggering area of ​​the first sliding control is the touch screen on the right side and is not set to a transparent color, the first progress bar control (i.e. Figure 8 and Fig. 9 30) is not transparent either.

[0225] For the second sliding control, in addition to the triggering area of ​​the second sliding control being the entire touch screen and being set to a transparent color, the second progress bar control corresponding to the second slider control is also transparent.

[0226] As described above, the air deflector position can be controlled locally / remotely based on the centralized control panel 10, and the corresponding air deflector picture P can also be displayed at the same time.

[0227] In some embodiments of the present application, see Fig.10 , the centralized control system may include a cloud platform 30' and a terminal device 40'.

[0228] The centralized control screen 10 is connected to the cloud platform 30 ′ via a communication module (such as a WiFi module) to achieve interaction with the cloud platform 30 ′.

[0229] The terminal device 40 ′ includes a type of device installed with an application program APP for controlling, for example, a central air conditioner, such as a smart phone, a tablet computer (PAD), and a personal PC.

[0230] As described above, after the centralized control screen 10 is successfully connected to the multi-split central air conditioner, the centralized control screen 10 reports the status of the multi-split central air conditioner (for example, the air outlet type of the air guide plate and the number of gears of the air guide plate) to the cloud platform 30' through the communication module, and the APP on the terminal device 40' completes the connection and binding of the centralized control screen 10 and the multi-split central air conditioner through the cloud platform 30'.

[0231] Therefore, the user can operate the corresponding air guide plate gear on the APP and send the second air guide plate gear adjustment instruction to the corresponding indoor unit, such as the control unit in the indoor unit.

[0232] The control unit sends a driving signal to the air guide plate driving motor to adjust the gear position of the air guide plate.

[0233] The air deflector control performed after the APP operates the corresponding air deflector gear position is the same as the control effect produced by operating the button 20 / 20' on the centralized control screen 10 to control the air deflector gear position, and will not be described in detail here.

[0234] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0235] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
