Description

Technical Field

[0002] In related technologies, existing conventional air conditioning products, including split units, ducted units, modular units, and dehumidifiers, primarily use the following display methods: VLED, indicator lights, and wired controllers. Indicator light displays use LED indicators and digital tubes to show the machine's on / off status, mode, fan speed, and temperature. VLED displays use VLED light-emitting modules to display simple numbers / letters and icons to show the machine's status (on / off, mode, fan speed, temperature, etc.). Wired controllers use wired controllers with LCD screens, which can be backlit segmented LCD screens or color LCD screens, depending on the requirements.

[0003] However, for existing display methods, apart from dot-matrix LCD displays, other display methods can only indicate the machine status by lighting up indicator lights or icons. The display format is simple and the display content is limited. Dot-matrix LCD displays have relatively rich content, however, the cost of dot-matrix LCD displays is too high. In addition, for existing display methods, the design position of the display module in some models will cause a certain loss in the amount of air return air of the air conditioner, such as the display box of split wall-mounted air conditioners, which will affect the air conditioning effect.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0076] In the description of this application, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0078] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0079] In some cases, existing conventional air conditioning products, including split units, ducted units, modular units, and dehumidifiers, primarily use the following display methods: VLED, indicator lights, and wired controllers. Indicator light displays use LED indicators and digital tubes to show the machine's on / off status, mode, fan speed, and temperature. VLED displays use VLED light-emitting modules to display simple numbers / letters and icons to show the machine's status (on / off, mode, fan speed, temperature, etc.). Wired controllers use wired controllers with LCD screens, which can be backlit segmented LCD screens or color LCD screens, depending on the requirements.

[0080] However, for existing display methods, apart from dot-matrix LCD displays, other display methods can only indicate the machine status by lighting up indicator lights or icons. The display format is simple and the display content is limited. Dot-matrix LCD displays have relatively rich content, however, the cost of dot-matrix LCD displays is too high. In addition, for existing display methods, the design position of the display module in some models will cause a certain loss in the amount of air return air of the air conditioner, such as the display box of split wall-mounted air conditioners, which will affect the air conditioning effect.

[0081] Based on the above, this application proposes a fan, an air conditioner, a control method for the air conditioner, and a computer-readable storage medium, aiming to improve the richness of the displayed content at low cost, and also to solve the problem that the location of the existing display panel affects the return air.

[0082] The various embodiments of the wind turbine of this application will be further described below with reference to the accompanying drawings.

[0083] In one embodiment, such as Figures 1 to 2 As shown, the fan includes, but is not limited to, a wind turbine 100, a motor 200, a display circuit board 300, and a control circuit board 400. The wind turbine 100 is provided with multiple blades 110, and at least one blade 110 integrates a display circuit board 300, which is provided with multiple LED light sources 310. In addition, a motor shaft 210 is provided on the front end face of the motor 200 facing the wind turbine 100, and the motor 200 is connected to the wind turbine 100 through the motor shaft 210. Furthermore, the control circuit board 400 is sleeved on the motor shaft 210 and connected to the display circuit board 300.

[0084] Specifically, when the motor 200 rotates, it drives the impeller 100 to rotate. Simultaneously, the control circuit board 400 controls the on / off state of the LED light source 310 on the display circuit board 300, allowing the LED light source 310 to display target information during rotation. When the impeller 100 rotates the display circuit board 300 together, due to the persistence of vision, the display area changes from a single-line display to an m*n dot matrix display. As the impeller 100 rotates the display circuit board 300 to different positions, the program controls the illumination of one or more different combinations of LED light sources 310, displaying letters, numbers, Chinese characters, patterns, scrolling marquees, animations, etc., within the m*n dot matrix display area.

[0085] Among them, such as Figure 3 As shown, in this embodiment of the application, a fan blade 110 with an integrated display circuit board 300 can be installed at the A notch position, so that the display circuit board 300 and the fan wheel 100 can be integrated into one unit, and the display circuit board 300 becomes part of the fan wheel 100.

[0086] It is worth noting that, firstly, in this embodiment, after the display circuit board 300 rotates together with the impeller 100, the display area changes from a fixed character / icon display to a dot matrix display, which is similar to the effect of a segmented LCD and a dot matrix LCD. Moreover, the display content is controlled by the program, and in addition to displaying icons and characters, it can also display Chinese characters, patterns, marquees, animations, etc. Therefore, this embodiment can better improve the richness of the display content at a low cost. In addition, in this embodiment, the display circuit board 300 is integrated with the impeller 100, and the display circuit board 300 becomes part of the impeller 100, which will not cause loss of airflow and solves the problem of the existing display board location affecting the return air.

[0087] Among them, the multiple LED light sources 310 on the display circuit board 300 can be as follows: Figure 6 The linear arrangement shown can also be arranged in a matrix, or arbitrarily as needed; this application embodiment does not impose specific limitations on this. Furthermore, the LED light source 310 described above can be an LED light source or other types of light sources; this application embodiment does not impose specific limitations on this.

[0088] In one embodiment, such as Figures 1 to 3 As shown, the aforementioned impeller 100 can be a cross-flow impeller 100. The structure of a cross-flow impeller 100 typically includes a multi-bladed, elongated cylindrical impeller with forward-curving multi-airfoil blades. When the impeller rotates, airflow enters the blade cascade from the open end of the impeller, passes through the interior of the impeller, and then exits into the volute from the other side of the blade cascade, forming the working airflow. Inside the impeller, the airflow velocity field is unstable, and a vortex exists, centered near the volute tongue. The presence of this vortex affects the airflow at the impeller output end, generating a circulating flow, which in turn affects the performance of the fan.

[0089] It should be noted that the display circuit board 300 can be integrated onto one or more fan blades 110 of the impeller 100. Specifically, the display circuit board 300 can be mounted on the surface of the fan blade 110, thereby achieving the effect of both increasing the air outlet area and displaying operating information.

[0090] Additionally, it should be noted that the position of the fan blade 110 selected for the display circuit board 300 can be the fan blade 110 on the side of the impeller 100 closest to the motor 200, such as... Figure 1 and Figure 2As shown, the length of the wires between the display circuit board 300 and the control circuit board 400 can be shortened to reduce wiring trouble; or the fan blade 110 can be selected according to the height required for the display content. For example, if the indoor unit is a cylindrical vertical indoor unit, if you want to display the content at a higher position, you can choose a taller fan blade 110, and if you want to display the content at a lower position, you can choose a shorter fan blade 110.

[0091] Additionally, it should be noted that when the motor shaft 210 rotates, it drives the impeller 100, the display circuit board 300, and the control circuit board 400 to rotate synchronously. Therefore, the wires between the circuit board and the control circuit board 400 will also rotate synchronously, meaning that there will be no problem of wires getting tangled and affecting the overall rotation.

[0092] In one embodiment, the mounting structure between the control circuit board 400 and the motor shaft 210 is as follows: the motor 200 has a non-standard motor shaft, for example, a D-shaped cross-section. In this embodiment, a non-standard hole corresponding to the cross-sectional shape of the motor shaft 210 can be formed at the center of the control circuit board 400, such as... Figure 4 As shown, for example, a D-shaped irregular hole, the control circuit board 400 is fitted onto the motor shaft 210 through the irregular hole, so that the motor shaft 210 can drive the control circuit board 400 to rotate synchronously without slipping.

[0093] It is understood that the aforementioned irregular shape can be a D-shape, a triangle, a quadrilateral, or other shapes, and this application does not specifically limit it in this way.

[0094] In one embodiment, such as Figure 5 As shown, the control circuit board is equipped with a power supply module 410, a control chip 420, a communication module 430, a position detection module 440, and an LED control interface 450. The power supply module 410 is used to supply power to the control chip 420. The control chip 420 is also connected to the communication module 430, the position detection module 440, and the LED control interface 450. The communication module 430 is used to receive control signals, the position detection module 440 is used to detect the rotation position of the wind turbine 100, and the LED control interface 450 is connected to the display circuit board 300.

[0095] In one embodiment, the control circuit board can also detect the wind turbine speed, and its detection circuit can be a micro switch, Hall sensor, infrared sensor, magnetic code disk, etc.

[0096] Based on the fans in the above embodiments, the following presents various embodiments of the indoor unit and air conditioner of this application.

[0097] In one embodiment, the indoor unit of this application includes, but is not limited to, the fan of any of the above embodiments.

[0098] It is worth noting that since the indoor unit of this application embodiment includes the fan of any of the above embodiments, the specific implementation method and technical effect of the indoor unit of this application embodiment can refer to the specific implementation method and technical effect of the fan of any of the above embodiments.

[0099] In one embodiment, the air conditioner of this application includes, but is not limited to, an indoor unit and an outdoor unit connected to each other, wherein the indoor unit is provided with a fan of any of the above embodiments.

[0100] It is worth noting that, since the air conditioner of this application embodiment includes the indoor unit of any of the above embodiments, and the indoor unit of any of the above embodiments includes the fan of any of the above embodiments, the specific implementation method and technical effect of the air conditioner of this application embodiment can refer to the specific implementation method and technical effect of the fan of any of the above embodiments.

[0101] Based on the fan, indoor unit, and air conditioner of the above embodiments, the following are various embodiments of the control method of the air conditioner of this application.

[0102] like Figure 7 As shown, Figure 7 This is a flowchart of a control method for an air conditioner provided in one embodiment of this application; the flowchart includes, but is not limited to, steps S710, S720 and S730.

[0103] Step S710: Obtain control signals;

[0104] Step S720: Determine the target display information based on the control signal;

[0105] Step S730: Control the fan wheel to rotate and drive the LED light source through the display circuit board so that the LED light source displays the target information during rotation.

[0106] In one embodiment, the air conditioner receives various control signals, such as power-on signals, power-off signals, or adjustment signals. Then, the air conditioner determines the corresponding target display information to be displayed based on the type of control signal. Next, the air conditioner controls the fan wheel to rotate, and during the rotation of the fan wheel, it controls the LED light source of the display circuit board to emit light through the control circuit board. When the fan wheel drives the display circuit board to different positions, the program controls one or more different combinations of LED light sources to light up, so as to display target display information such as letters, numbers, Chinese characters, patterns, marquee lights, and animations within an m*n dot matrix display range.

[0107] In addition, such as Figure 8 As shown, Figure 8 This is a flowchart of a control method for an air conditioner provided in another embodiment of this application; regarding the above step S730, driving the LED light source through the display circuit board, it may include, but is not limited to, steps S810 and S820.

[0108] Step S810: When the rotational speed of the wind turbine is not zero, determine the display refresh rate based on the rotational speed;

[0109] Step S820: Control the display circuit board to drive the LED light source at the display refresh rate.

[0110] In one embodiment, if the air conditioner needs to drive the LED light source at a certain display refresh rate so that the human eye can clearly see the target display information displayed by the LED light source during rotation when the fan is rotating, the air conditioner can determine the display refresh rate based on the rotation speed and drive the LED light source according to the display refresh rate.

[0111] In one embodiment, the specific calculation process for the display refresh rate can be as follows: First, determine the rotation time of one revolution of the wind turbine based on the rotation speed; then, determine the display refresh rate based on the target pixel, the target multiplier, and the rotation time. The display refresh rate can be calculated using the following formula: f = x * n * (1 / t), where f is the display refresh rate, x is the target multiplier, n is the target pixel, and t is the rotation time. That is, the display refresh rate is the ratio of the product of the target pixel and the target multiplier to the rotation time.

[0112] It should be noted that in actual installation, the air conditioner casing usually surrounds the cross-flow fan, and an air outlet area needs to be created on the air conditioner casing for air output. Therefore, the air conditioner only outputs air from the air outlet area, not from all sides. So, it is only necessary to display the target information in the air outlet area. In fact, the display refresh rate can be calculated by the following formula: f=k*x*n*(1 / t), where k is the angular ratio coefficient of the air conditioner's air outlet area to the circumferential area, f is the display refresh rate, x is the target multiple, n is the target pixel, and t is the rotation time. That is, the display refresh rate is the ratio of the product of the angular ratio coefficient, the target pixel, and the target multiple to the rotation time.

[0113] In addition, such as Figure 9 As shown, Figure 9 This is a flowchart of a control method for an air conditioner provided in another embodiment of this application; the control method for the air conditioner may also include, but is not limited to, steps S910 and S920.

[0114] Step S910: Determine that the wind turbine rotation speed cannot be obtained or that the wind turbine rotation speed is zero;

[0115] Step S920: Control the display circuit board to drive the LED light source to flash as an alarm.

[0116] In one embodiment, if the air conditioner cannot know the current speed of the fan wheel, or if the air conditioner detects that the fan wheel is not rotating, it indicates that the air conditioner cannot ensure that the target display information can be displayed through the fan wheel and the display circuit board. In this case, the air conditioner will drive the LED light source through the display circuit board to flash as an alarm, thereby informing and reminding the user to check and repair in time.

[0117] In one embodiment, when no control signal is acquired, if historical display information is stored, the LED light source is driven by the display circuit board so that the LED light source displays the historical display information during rotation; when no control signal is acquired, if no historical display information is stored, the LED light source is driven by the display circuit board so that the LED light source displays error information during rotation.

[0118] Specifically, if the air conditioner receives a control signal, it will display new information corresponding to the control signal through the display circuit board. If the air conditioner does not receive a control signal, that is, when the air conditioner does not need to display new information, it will determine whether there is old information. If there is old information, the air conditioner will continue to display the old information through the display circuit board. If there is no old information, the air conditioner will display an error message through the display circuit board.

[0119] In one embodiment, the determination of target display information based on the control signal in step S720 can include, but is not limited to, the following three implementations, which are as follows:

[0120] In the first implementation scenario, when the control signal is a power-on signal, power-on display information is generated based on the power-on signal. Specifically, when the air conditioner receives the power-on signal, it will respond by generating power-on display information such as "Powering on" or a preset temperature. Then, the air conditioner will display the power-on display information through a rotating LED light source. For example, the rotating LED light source will display characters such as "Powering on" or "26℃".

[0121] In the second implementation scenario, when the control signal is an adjustment signal, operating parameter display information is generated based on the adjustment signal. Specifically, when the air conditioner receives the adjustment signal, it will respond by generating operating parameter display information such as temperature adjustment information, fan speed adjustment information, or air direction adjustment information. Then, the air conditioner will display the operating parameter display information through a rotating LED light source. For example, the rotating LED light source will display characters such as "temperature 25℃", "fan speed 80%" or "left and right swing".

[0122] In the third implementation scenario, when the control signal is a shutdown signal, shutdown display information is generated based on the shutdown signal. Specifically, when the air conditioner receives the shutdown signal, it will respond by generating shutdown display information such as "Shutting down". Then, the air conditioner will display the shutdown display information through a rotating LED light source. For example, the rotating LED light source will display the characters "Shutting down".

[0123] In addition, such as Figure 10 As shown, Figure 10 This is a flowchart of a control method for an air conditioner provided in another embodiment of this application; the control method for the air conditioner may also include, but is not limited to, steps S1010, S1020 and S1030.

[0124] Step S1010: When the control signal is a power-on signal or an adjustment signal, obtain the light intensity of the current environment;

[0125] Step S1020: When the light intensity is less than the preset light intensity, the LED light source is turned off by controlling the display circuit board;

[0126] Step S1030: When the light intensity is greater than or equal to the preset light intensity, continue to drive the LED light source through the display circuit board.

[0127] In one embodiment, when the air conditioner receives a power-on signal or an adjustment signal, it will also determine whether to continue displaying information using LED light sources based on the current ambient light level. Specifically, the air conditioner can detect the current ambient light intensity using a light sensor. If the current ambient light intensity is less than a preset light intensity, it may indicate that it is currently nighttime sleep time, in which case the LED light source can be turned off. If the current ambient light intensity is greater than or equal to the preset light intensity, it may indicate that it is currently daytime, in which case the LED light source can be turned on.

[0128] A light sensor, in particular, is a device that senses the intensity of ambient light. It can control the air conditioner's operating mode based on changes in indoor light to achieve energy savings and improve comfort. The light sensor in the air conditioner can automatically adjust brightness to adapt to different ambient light conditions. For example, when the ambient brightness is high, the LED light source will automatically adjust to high brightness; while in a darker environment, the LED light source will adjust to low brightness or turn off, achieving automatic brightness adjustment. This automatic adjustment not only improves the user's viewing experience but also helps extend the lifespan of the LED light source and save energy.

[0129] It is understood that the aforementioned preset light intensity can be pre-set, and this application embodiment does not specifically limit it.

[0130] In another embodiment, the air conditioner can also turn off the photosensitive function, that is, stop controlling the LED light source according to the current ambient light intensity. Specifically, when the air conditioner receives a photosensitive turn-off command sent by the user, if the light intensity is less than the preset light intensity, the air conditioner will still continue to drive the LED light source through the display circuit board.

[0131] For example, when a user sends a photosensitive shutdown command to the air conditioner via a mobile app or remote control, the air conditioner will turn off the photosensitive function. Even after the lights are turned off at night, the air conditioner will keep the LED light source lit.

[0132] In addition, such as Figure 11 As shown, Figure 11 This is a flowchart of a control method for an air conditioner provided in another embodiment of this application; the control method for the air conditioner may also include, but is not limited to, steps S1110, S1120 and S1130.

[0133] Step S1110: When the control signal is a shutdown signal, obtain the operating status of the indoor unit;

[0134] Step S1120: When the indoor unit is performing anti-mold treatment, obtain the anti-mold treatment time. When the anti-mold treatment time is less than the preset time, keep the fan wheel rotating and keep driving the LED light source through the display circuit board. When the anti-mold treatment time is greater than or equal to the preset time, stop the fan wheel rotating and control the LED light source to turn off through the display circuit board.

[0135] Step S1130: If the indoor unit has not undergone anti-mold treatment, control the fan wheel to stop rotating and control the LED light source to turn off via the display circuit board.

[0136] In one embodiment, if the air conditioner receives a shutdown signal, it will respond by obtaining its own operating status. If the air conditioner is currently performing indoor unit anti-mold treatment, i.e., the anti-mold treatment time is less than the preset duration, it indicates that the indoor unit's fan wheel is still rotating. At this time, a shutdown display message can be sent to the display circuit board, and the shutdown display message can be displayed through the display circuit board. If the air conditioner is not currently performing indoor unit anti-mold treatment, or has already completed indoor unit anti-mold treatment, i.e., the anti-mold treatment time is greater than or equal to the preset duration, it indicates that the indoor unit's fan wheel has stopped rotating. At this time, the shutdown display message cannot be displayed through the display circuit board, and the air conditioner can choose not to light up the LED light source.

[0137] It should be noted that the above-mentioned anti-mold treatment can be achieved by running the indoor unit's fan for a period of time to dry the moisture in the indoor unit's heat exchanger. Below are some specific anti-mold treatment methods:

[0138] The first method of preventing mold growth is air deflector control: by controlling the air deflector to swing intermittently or continuously at different opening angles, the condensation at different locations in the air duct can be evaporated in a concentrated manner, and the temperature of the air duct can be gradually brought closer to the temperature of the indoor return air vent, thus achieving the drying and mold prevention of the air duct.

[0139] The second method of mold prevention treatment involves reversing the indoor fan: In mold prevention treatment, the indoor fan can be controlled to rotate in the opposite direction to its rotation direction in cooling or dehumidification mode to promote drying inside the air conditioner.

[0140] The third method of mold prevention treatment is temperature difference control: by monitoring the temperature change of the indoor heat exchanger, when the first temperature difference (the difference between the indoor heat exchanger temperature and the temperature at the time of shutdown) is greater than or equal to the preset rise threshold, the operation of the compressor, indoor fan and electric auxiliary heater can be stopped, and the mold prevention treatment can be terminated.

[0141] The fourth method of mold prevention is automatic mold prevention operation: Based on the current operating mode, ambient temperature, and relative humidity, it is determined whether the conditions for automatic mold prevention are met. If the conditions are met, the air conditioner will perform automatic mold prevention operation when it receives a shutdown signal. For example, it will control the compressor and outdoor fan to stop, and the indoor fan to run at a low speed for a period of time before stopping, in order to dry the moisture in the evaporator.

[0142] The fifth method of preventing mold growth is the default anti-mold function: Some air conditioners have a default anti-mold function. After being turned off in cooling, dehumidifying, or automatic (cooling) mode, the air conditioner will continue to run at a low speed for a period of time, such as 10 minutes, to dry the moisture in the evaporator and prevent mold growth.

[0143] It is understood that the aforementioned preset duration can be pre-set, and this application embodiment does not specifically limit it.

[0144] In addition, such as Figure 12 As shown, Figure 12 This is a flowchart of a control method for an air conditioner provided in another embodiment of this application; the control method for the air conditioner may also include, but is not limited to, steps S1210, S1220 and S1230.

[0145] Step S1210: Obtain the operating status of the air conditioner;

[0146] Step S1220: When the air conditioner is operating normally, continue to drive the LED light source through the display circuit board;

[0147] Step S1230: When the air conditioner is in an abnormal operating state, detect the operating state of the fan. When the fan is in a normal operating state, keep driving the LED light source through the display circuit board. When the fan is in an abnormal operating state, sound an alarm through the buzzer.

[0148] In one embodiment, before displaying the target information, the air conditioner also obtains its own operating status. If the air conditioner's operating status is normal, it indicates that the target information can be displayed successfully. In this case, the air conditioner will continue to display the target information by driving the LED light source through the display circuit board. If the air conditioner's operating status is abnormal, the operating status of the fan needs to be further detected. If the fan's operating status is normal, it indicates that the target information can be displayed successfully. In this case, the air conditioner will continue to display the target information by driving the LED light source through the display circuit board. If the air conditioner's operating status is abnormal, it indicates that the target information will not be displayed successfully. In this case, the air conditioner will sound an alarm through a buzzer to remind the user to have it repaired in time.

[0149] Based on the control methods of the air conditioner in the above embodiments, the embodiments of this application have the following technical effects: First, the display methods of existing air conditioning products, regardless of whether indicator lights or VLED display modules are used, can only display fixed information content. With the display method of this application embodiment, when the display panel rotates together with the fan wheel, the display area changes from a fixed character / icon display to a dot matrix display (the effect is similar to a segmented LCD and a dot matrix LCD). The display content is controlled by the program, and in addition to icons and characters, it can also display Chinese characters, patterns, marquee lights, animations, etc. Second, in existing wall-mounted air conditioners, the display panel is usually installed on the front panel. When the panel is closed, the display panel and display box need to occupy a certain amount of air duct space. Although the thickness of the display box is only about 16mm, it still causes a certain loss of the air return volume of the air conditioner, which reduces the overall cooling / heating effect. With the display method of this application embodiment, the display panel and the fan wheel are integrated into one unit, and the display panel becomes part of the fan wheel, which will not cause any loss of air volume.
