In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0036] A vertical air conditioner and a control method and a control device thereof provided by the present invention are described below with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, the vertical air conditioner according to the first embodiment of the present invention includes an air conditioner body 1, a centrifugal fan 4 and a cross-flow fan 5.

[0038] The air conditioner body 1 is provided with a first air inlet and outlet portion 2 and a second air inlet and outlet portion 3 in sequence from top to bottom.

[0039] A centrifugal fan 4 is installed in the first air inlet and outlet portion 2, and a first annular air outlet 22 is provided on the outer peripheral wall of the first air inlet and outlet portion 2. A cross-flow fan 5 is installed in the second air inlet and outlet portion 3, and a second air inlet 31 and a second air outlet 32 ​​are provided on the outer peripheral wall of the second air inlet and outlet portion 3. The cross-flow fan 5 is arranged relative to the evaporator.

[0040] It can be understood that in the vertical air conditioner, the centrifugal fan 4 is installed in the first air inlet and outlet part 2 and is located above the cross-flow fan 5, responsible for axially taking in air from the lower side and then radially discharging air from the first air outlet 22. The main function of the centrifugal fan 4 is to generate horizontal airflow in the heating mode to form an air curtain to prevent hot air from rising to the top of the room.

[0041] The cross-flow fan 5 is installed in the second air inlet and outlet portion 3 and is located below the centrifugal fan 4. It is responsible for radially taking in air from the second air inlet 31 and then radially discharging air from the second air outlet 32. The main function of the cross-flow fan 5 is to send heated air into the room in the heating mode to provide a heating effect.

[0042] Specifically, the basic working principle of the vertical air conditioner protected by the present invention is as follows: the vertical air conditioner achieves efficient heating and temperature distribution optimization through the coordinated work of two main components (i.e., the centrifugal fan 4 and the cross-flow fan 5). The cross-flow fan 5 is located at the lower part of the air conditioner body 1, sucks in cold air from the second air inlet 31, and sends out hot air from the second air outlet 32 ​​after being heated by the evaporator. The centrifugal fan 4 is located at the upper part, generating horizontal airflow, forming a "wind curtain", forming an air isolation layer at a specific height of the room, preventing hot air from rising to the top of the room, thereby maintaining a uniform distribution of indoor temperature.

[0043] Furthermore, the working process of the vertical air conditioner of the present invention is described as follows: when the vertical air conditioner receives the instruction of the heating mode, the compressor is first started and put into a stable operating state, and the inlet temperature of the evaporator is detected at the same time. When the temperature reaches the set value, the cross-flow fan 5 is turned on to send the heated air into the room. After a period of time, in order to prevent the hot air from rising, the control device will turn on the centrifugal fan 4 to generate a horizontal airflow to form an air curtain. When shutting down, the centrifugal fan 4 is turned off first, and then the wind speed of the cross-flow fan 5 is reduced to the buffer wind speed. After running continuously for a period of time, it is completely turned off to ensure that the indoor temperature drops steadily.

[0044] In the related art, due to the low density of hot air, it will rise rapidly during the heating process, resulting in too high a temperature at the top and a low temperature at the bottom. Even if the existing art uses adjusting guide plates and swing blades to change the direction of air flow, it is difficult to fundamentally solve this problem, because these methods can only change local airflow and cannot effectively prevent the rise of hot air. As a result, it still takes a long time for the temperature field in the room to reach equilibrium, affecting the user's comfort and causing energy waste.

[0045] Therefore, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention adds an air curtain function module (that is, the centrifugal fan 4) on the top of the vertical air conditioner to form a horizontal air curtain to isolate the cold and hot air and prevent the hot air from rising, thereby effectively improving the temperature distribution in the house and enhancing the heating effect and energy efficiency of the air conditioner.

[0046] Furthermore, compared with the related art, the present invention has the following advantages.

[0047] (1) Uniform temperature distribution: By adding an air curtain function module on the top of the air conditioner, horizontal airflow is generated to form an air curtain, which effectively prevents hot air from rising, maintains a uniform distribution of indoor temperature, and significantly improves user comfort.

[0048] (2) Improved energy efficiency: The air isolation layer formed by the wind curtain functional module reduces the mixing of cold and hot air, improves the energy efficiency of the air conditioner, reduces energy waste, and has significant energy-saving advantages.

[0049] (3) Improved user experience: The wind curtain effectively controls the rise of hot air and maintains the stability of different temperature zones in the room. Especially in heating mode, it significantly improves the problem of low bottom temperature and improves user comfort.

[0050] (4) Easy operation: The opening and closing of the air curtain function module is automatically managed by the control system. Users only need to select the heating mode to enjoy uniform temperature distribution. It is easy to operate and provides a good user experience.

[0051] (5) System stability: Through the precise control of the air curtain function module, the system can achieve a stable temperature distribution more quickly, shorten the time to achieve the expected temperature effect, and improve the overall stability of the system.

[0052] (6) Extending equipment life: By reducing the mixing of cold and hot air, the air conditioning system can reach the desired temperature more efficiently, reducing the operating time and load of the equipment, thereby extending the service life of the equipment.

[0053] (7) Quick response: The quick response characteristics of the air curtain function module enable the air conditioner to quickly adjust the airflow when starting and shutting down, ensuring that the indoor temperature quickly reaches and is maintained within the set range.

[0054] (8) Multifunctional adaptability: In addition to the heating mode, the air curtain function module can also play an auxiliary role in other working modes (such as cooling mode), enhancing the overall performance and adaptability of the air conditioner.

[0055] In summary, the present invention not only significantly improves the heating effect and energy efficiency of the air conditioner by adding an air curtain function module on the top of the vertical air conditioner, but also improves the user's comfort and usage experience. It has the multiple advantages of easy operation, stable system, extended equipment life and environmental friendliness.

[0056] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first air inlet and outlet 2 is separated from the second air inlet and outlet 3 by a partition 6, and a first air inlet 21 is provided on the partition 6, and both ends of the first air inlet 21 are respectively connected to the first air inlet and outlet 2 and the second air inlet and outlet 3.

[0057] In this embodiment, the main function of the partition 6 is to separate the first air inlet and outlet 2 from the second air inlet and outlet 3 to ensure that the airflows of the two parts do not interfere with each other, thereby improving the efficiency and stability of the system.

[0058] The partition plate 6 is provided with a first air inlet 21, and both ends of the first air inlet 21 are respectively connected to the first air inlet and outlet 2 and the second air inlet and outlet 3, allowing air flow to flow between the two parts. Specifically, the first air inlet 21 allows the centrifugal fan 4 to inhale air from the second air inlet and outlet 3, thereby generating a horizontal airflow and forming an air curtain.

[0059] The airflow path of the crossflow fan 5 is as follows: the crossflow fan 5 inhales cold air from the second air inlet 31, and after being heated by the evaporator, sends out hot air from the second air outlet 32. The airflow path of the centrifugal fan 4 is as follows: the centrifugal fan 4 inhales air from the second air inlet and outlet 3 through the first air inlet 21 on the partition 6, and then radially discharges air from the first air outlet 22 to form a horizontal airflow, i.e., an air curtain.

[0060] It should be explained that the air curtain formation process is as follows: the centrifugal fan 4 inhales air from the second air inlet and outlet 3 through the first air inlet 21. This part of the air can be heated air or unheated air, depending on the working state of the cross-flow fan 5. The inhaled air is radially discharged from the first air outlet 22 to form a horizontal airflow, i.e., an air curtain. The air curtain forms an effective air isolation layer at a specific height of the room, preventing hot air from rising to the top of the room, thereby achieving the separation of indoor temperature zones.

[0061] As described above, the partition 6 of this embodiment not only separates the first air inlet and outlet 2 and the second air inlet and outlet 3, but also provides a communication path for the airflow through the first air inlet 21, ensuring that the airflows of the two parts can work in coordination. And through the design of the partition 6 and the first air inlet 21, the system can better control the flow direction and speed of the airflow, optimize the airflow distribution, and improve the heating effect and energy efficiency of the air conditioner.

[0062] In addition, the design of the partition 6 and the first air inlet 21 makes the airflow path more reasonable, reduces the mixing of cold and hot air, improves the energy efficiency of the air conditioner, and reduces energy waste. The separation function of the partition 6 and the connection function of the first air inlet 21 ensure that the airflows of the two parts do not interfere with each other, improves the overall stability of the system, and shortens the time to achieve the expected temperature effect.

[0063] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the central axis of the first air inlet 21, the central axis of the centrifugal fan 4, and the central axis of the cross-flow fan 5 all coincide with each other.

[0064] Thus, on the one hand, through the design of axis overlap, the centrifugal fan 4 can more effectively inhale air from the second air inlet and outlet 3, form a horizontal airflow, effectively prevent the hot air from rising, maintain the uniform distribution of indoor temperature, and improve the user's comfort. On the other hand, the design of axis overlap makes the airflow path more direct and smooth, reduces the resistance and energy loss of the airflow, improves the energy efficiency of the air conditioner, and reduces energy waste.

[0065] In addition, the design of axis overlap ensures the stability and uniformity of airflow, improves the overall stability of the system, and shortens the time to achieve the expected temperature effect.

[0066] According to some embodiments of the present invention, the vertical air conditioner further includes a first motor, a second motor and a control device.

[0067] The first motor and the second motor are respectively connected to the centrifugal fan 4 and the cross-flow fan 5. The control device is respectively connected to the first motor and the second motor, and the control device is used to control and adjust the working state of the first motor and / or the second motor according to the target working mode and working parameters of the vertical air conditioner.

[0068] In this embodiment, the first motor is connected to the centrifugal fan 4. The first motor is responsible for driving the operation of the centrifugal fan 4. By controlling the rotation speed of the first motor, the horizontal airflow intensity generated by the centrifugal fan 4 can be adjusted, thereby controlling the formation and intensity of the air curtain.

[0069] The second motor is connected to the cross-flow fan 5. The second motor is responsible for driving the operation of the cross-flow fan 5. By controlling the rotation speed of the second motor, the air supply volume of the cross-flow fan 5 can be adjusted, thereby controlling the adjustment speed and uniformity of the indoor temperature.

[0070] The control device intelligently adjusts the working state of the first motor and the second motor according to the target working mode (such as heating mode, cooling mode, defrosting mode, etc.) of the vertical air conditioner and its working parameters. The working parameters include but are not limited to the reading of the temperature sensor, the indoor temperature setting value, the operating state of the compressor, etc.

[0071] Specifically, the control device can dynamically adjust the speed of the first motor and the second motor according to the target working mode and working parameters. For example, in the heating mode, when it is necessary to form an air curtain, the control device will start the first motor to make the centrifugal fan 4 generate horizontal airflow; when it is necessary to supply air for heating, the control device will start the second motor to make the crossflow fan 5 send the heated air into the room.

[0072] In this way, through the above method, the control device can dynamically adjust the rotation speed of the centrifugal fan 4 and the cross-flow fan 5 to ensure that the system operates efficiently in different modes, thereby achieving uniform distribution of indoor temperature and improved energy efficiency.

[0073] In summary, the vertical air conditioner of the present invention effectively solves the problem of excessively high top temperature and low bottom temperature caused by the rising hot air during the heating process by adding an air curtain functional module to the top of the air conditioner. Compared with the traditional technical solution, the air curtain of the present invention can form an effective air isolation layer to prevent the hot air from rising and maintain a uniform temperature distribution in the room, thereby significantly improving the user's comfort. In addition, since the mixing of cold and hot air is reduced, the present invention also improves the energy efficiency of the air conditioner, reduces energy waste, and has significant energy-saving advantages. These advantages make the present invention have important application value in improving air conditioning performance and user experience.

[0074] The control method and control device of the vertical air conditioner proposed by the present invention are described below with reference to the accompanying drawings. Before describing the embodiments of the present invention in detail, the entire application scenario is described first. The control method, control device, electronic device and computer-readable storage medium of the vertical air conditioner of the embodiment of the present invention can be applied to the vertical air conditioner locally, to the cloud platform in the Internet field, or to other types of cloud platforms in the Internet field, or to third-party devices. The third-party device may include many different types such as mobile phones, tablet computers, notebooks, car computers and other smart terminals.

[0075] The following description only takes the control method applicable to a vertical air conditioner as an example. It should be understood that the control method of the embodiment of the present invention can also be applied to a cloud platform and a third-party device.

[0076] like Figure 3 As shown, a control method for a vertical air conditioner according to a second aspect of the present invention includes: Step S1, obtaining a target operating mode of the vertical air conditioner; Step S2, controlling and adjusting the working state of the centrifugal fan 4 and / or the cross-flow fan 5 according to the target working mode of the vertical air conditioner.

[0077] Specifically, in the control method, the system receives a user instruction and identifies a target working mode of the vertical air conditioner. According to the target working mode, the control device intelligently adjusts the working state of the first motor and the second motor, controls the operation of the centrifugal fan 4 and the cross-flow fan 5, ensures that the system operates efficiently in different modes, and realizes uniform distribution of indoor temperature and improvement of energy efficiency.

[0078] Through this control method, the vertical air conditioner can automatically adjust the working status of the fan in different working modes to ensure that users get the best user experience and energy efficiency performance.

[0079] According to some embodiments of the present invention, the step of controlling and adjusting the working state of the centrifugal fan 4 and / or the cross-flow fan 5 according to the target working mode of the vertical air conditioner specifically includes: When the target working mode is the heating mode, controlling the vertical air conditioner to enter the heating mode; In the heating mode, the cross-flow fan 5 is controlled to operate according to the set heating wind speed, and the current working parameters of the vertical air conditioner are obtained; If it is determined that the current working parameters meet the air curtain opening condition, the centrifugal fan 4 is controlled to operate according to the set air curtain wind speed.

[0080] Further, when it is determined that the current working parameters meet the air curtain opening condition, in the step of controlling the centrifugal fan 4 to operate according to the set air curtain wind speed, the air curtain opening condition specifically includes: The inlet temperature of the evaporator is greater than or equal to the set temperature, and the cross-flow fan 5 operates at the set heating wind speed for at least a first set time period.

[0081] Based on the above embodiment, the specific control process during the heating process is as follows: the user selects the heating mode through the remote control, and the system receives the instruction. The control device identifies that the target working mode is the heating mode, and controls the vertical air conditioner to enter the heating mode. The control device starts the compressor and ensures that it enters a stable operating state, at which time the centrifugal fan 4 and the cross-flow fan 5 are both in the off state.

[0082] When the compressor is running stably, the control device detects the inlet temperature of the evaporator through the temperature sensor. If the inlet temperature of the evaporator reaches 35°C, it proves that the evaporator reaches a stable heating condition. The control device starts the second motor to drive the crossflow fan 5 to operate at the set heating wind speed (e.g., 1000 RPM), so that the crossflow fan 5 starts to supply air for heating.

[0083] The control device obtains the current working parameters of the vertical air conditioner in real time, including the inlet temperature of the evaporator and the running time of the cross-flow fan 5. Then, the control device determines whether the current working parameters meet the air curtain opening conditions, wherein the air curtain opening conditions include: whether the inlet temperature of the evaporator is greater than or equal to 35°C, and whether the cross-flow fan 5 runs continuously for at least 10 minutes at the set heating wind speed (1000RPM).

[0084] If the current working parameters meet the air curtain opening condition, the control device starts the first motor to drive the centrifugal fan 4 to operate at the set air curtain wind speed (e.g., 800 RPM). The centrifugal fan 4 generates horizontal airflow to form an air curtain to prevent hot air from rising to the top of the room.

[0085] According to some embodiments of the present invention, after the step of controlling the centrifugal fan 4 to operate according to the set wind curtain wind speed, the method further includes: When a shutdown command is received, the centrifugal fan 4 is controlled to be turned off, and the cross-flow fan 5 is controlled to be turned off after continuously running at the set buffer wind speed for a second set time period.

[0086] Specifically, in this embodiment, when the system receives a shutdown command input by the user through a remote controller, a panel or other control device, the shutdown process starts.

[0087] The control device first turns off the first motor and stops the operation of the centrifugal fan 4 to stop the formation of the air curtain. The control device reduces the speed of the second motor to a set buffer wind speed (e.g., 500 RPM) and continues to operate for a second set time (e.g., 5 minutes). This process ensures that the indoor temperature gradually and steadily decreases, avoiding temperature fluctuations caused by sudden air stoppage.

[0088] After the cross-flow fan 5 continuously operates at the set buffer wind speed for a second set time period, the control device further controls the second motor to shut down, completing the entire shutdown process.

[0089] According to some embodiments of the present invention, the step of controlling and adjusting the working state of the centrifugal fan 4 and / or the cross-flow fan 5 according to the target working mode of the vertical air conditioner specifically includes: When the target working mode is the cooling mode, controlling the vertical air conditioner to enter the cooling mode; In the cooling mode, the cross-flow fan 5 is controlled to operate at a set cooling wind speed, and the centrifugal fan 4 is controlled to remain in an off state.

[0090] For example, the user selects the cooling mode through the remote control, and the system receives the instruction. The control device identifies that the target working mode is the cooling mode, and controls the vertical air conditioner to enter the cooling mode. The control device starts the compressor and ensures that it enters a stable operating state, at which time the centrifugal fan 4 and the cross-flow fan 5 are both in the off state.

[0091] When the compressor is running stably, the control device detects the inlet temperature of the evaporator through the temperature sensor. If the inlet temperature of the evaporator reaches 15°C, it proves that the evaporator reaches a stable cooling condition. The control device starts the second motor to drive the crossflow fan 5 to operate at the set cooling wind speed (e.g., 800 RPM) so that the crossflow fan 5 starts to supply air for cooling. In the cooling mode, the control device ensures that the centrifugal fan 4 remains in the off state, and there is no need to form an air curtain.

[0092] The overall workflow of the control method of the vertical air conditioner of the present invention is summarized below.

[0093] First, the target operating mode of the vertical air conditioner is obtained, wherein the target operating mode can be a heating mode, a heating mode or a defrosting mode, etc. In a specific embodiment, when it is determined that the target operating mode is a cooling mode, that is, when an instruction to control the vertical air conditioner to enter the heating mode is received, the cross-flow fan 5 is controlled to operate at the set cooling wind speed to achieve cooling. At this time, there is no need to turn on the air curtain function. Therefore, in the cooling mode, the centrifugal fan 4 is always kept in a closed state.

[0094] In another specific embodiment, when it is determined that the target working mode is the heating mode, that is, when an instruction to control the vertical air conditioner to enter the heating mode is received, the compressor is first controlled to start and ensure that it enters a stable operating state. During the startup of the compressor, the centrifugal fan 4 and the cross-flow fan 5 are both in the off state (turning on at this time will produce cold air and affect the user experience). When the compressor is running stably, it is detected whether the inlet temperature of the evaporator reaches the set temperature (for example, 35°C). If the inlet temperature of the evaporator reaches the set temperature, it proves that the evaporator reaches a stable heating condition. At this time, the cross-flow fan 5 can be turned on to supply air to heat the room.

[0095] When the cross-flow fan 5 runs continuously for a first set time at the set heating wind speed, the hot air in the room will rise rapidly and concentrate at the top of the room due to the low density of the hot air in the room, resulting in uneven indoor temperature distribution. In this regard, the method of the present invention turns on the centrifugal fan 4 so that the centrifugal fan 4 generates a horizontal airflow, i.e., an air curtain. The air curtain can form an effective air isolation layer at a specific height of the room, preventing the hot air from rising to the top of the room, thereby achieving effective separation of temperature zones in the room.

[0096] Finally, when the shutdown command is received, the control device will first control the centrifugal fan 4 to turn off, and control the wind speed of the crossflow fan 5 to be reduced to the set buffer wind speed. After the crossflow fan 5 continues to run for the second set time, the control device further controls the crossflow fan 5 to turn off, thereby completing the entire heating process.

[0097] For example, a temperature sensor is provided at the inlet of the evaporator, the inlet temperature is Tin, the speed of the motor M1 of the crossflow fan 5 is RPM1, and the speed of the motor M2 of the centrifugal fan 4 is RPM2. The main control methods are as follows: Figure 4 shown.
