[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0038] It should be noted that the terms "first," "second," etc., used in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0039] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
[0040] The optional embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0041] The environmental humidity detection scheme described in this invention is applicable to air conditioners with a full water level detection function. Some air conditioners do not have a drain pipe and cannot drain water automatically. When these air conditioners are in cooling mode, the evaporator absorbs heat and evaporates, and the resulting condensate is generally stored in a water storage device (such as a water tank or drip tray) below the evaporator. In order to prevent condensate from overflowing the water tank and affecting the normal operation of the air conditioner, a full water level detection is required.
[0042] The water level detection function is achieved through a switching signal fed back from a level switch. The level switch is installed inside the water storage device of the air conditioner and is used to detect the water accumulation in the air conditioner. Specifically, when the water accumulation in the air conditioner reaches the height threshold at which the level switch opens, the level switch outputs a high-level signal; when the water accumulation in the air conditioner drops to the height threshold at which the level switch closes, the level switch outputs a low-level signal.
[0043] The signal output by the liquid level switch is related to the water level inside the air conditioner, and the water level inside the air conditioner is related to the moisture content in the air. The moisture content in the air can determine the humidity level of the environment. Therefore, by utilizing the relationship between the liquid level switch and the humidity level of the environment, a humidity level detection scheme that does not require the use of a humidity sensor is proposed.
[0044] Figure 1 This is a flowchart of the environmental humidity detection method provided in the embodiments of the present invention, such as... Figure 1 As shown, the method includes the following steps:
[0045] S101, acquire the signal output by the liquid level switch inside the air conditioner, wherein the liquid level switch is used to detect the water level inside the air conditioner.
[0046] S102 determines the ambient humidity level based on the current operating mode of the air conditioner and the signal output by the liquid level switch.
[0047] This embodiment determines the ambient humidity level based on the current operating mode of the air conditioner and the signal output by the liquid level switch inside the air conditioner. It eliminates the need for a humidity sensor and, based on the existing water level detection function of the air conditioner, achieves automatic detection of the ambient humidity level without increasing the cost of components, thereby realizing intelligent dehumidification of the air conditioner and optimizing air conditioning regulation.
[0048] After the air conditioner is turned on, the liquid level switch begins detection and outputs corresponding signals. Specifically, the signals output by the liquid level switch inside the air conditioner are acquired as follows: when the liquid level switch detects that the water level inside the air conditioner has reached a first height threshold, the liquid level switch opens, and a high-level signal is acquired; when the liquid level switch detects that the water level inside the air conditioner has dropped to a second height threshold, the liquid level switch closes, and a low-level signal is acquired; wherein, the first height threshold is greater than the second height threshold.
[0049] In one implementation, determining the ambient humidity level based on the current operating mode of the air conditioner and the signal output by the level switch includes:
[0050] In ventilation or heating mode, when the level switch continuously outputs a low-level signal, it indicates that the environment is dry and dehumidification is not required; when the level switch outputs a high-level signal, it indicates that the environment is humid.
[0051] In cooling or dehumidifying mode, the ambient humidity level is determined based on the frequency of the signal output by the level switch.
[0052] In cooling or dehumidifying mode, the indoor heat exchanger acts as an evaporator, absorbing heat and evaporating to produce condensate. The humidity level in this mode is determined by the frequency of the liquid level switch's operation. In ventilation or heating mode, the indoor heat exchanger does not produce condensate, and theoretically, the liquid level switch should remain off (i.e., continuously outputting a low-level signal). The environment is dry and dehumidification is not required. If the liquid level switch turns on (i.e., outputting a high-level signal), it indicates that the environment is humid. In this case, a dehumidification reminder can be output to remind the user that the environment is humid and dehumidification is necessary, preventing the user from directly entering dehumidification mode and causing a drop in indoor temperature, which would negatively impact the user experience.
[0053] This implementation combines the air conditioning operating mode and the signal output from the liquid level switch, enabling relatively accurate detection of the ambient humidity level without using a humidity sensor.
[0054] Furthermore, the ambient humidity level is determined based on the frequency of the signal output by the level switch, including:
[0055] (1) In cooling mode, when the liquid level switch continuously outputs a low-level signal (i.e., the liquid level switch is in the normally closed state), the environment is determined to be dry; if the liquid level switch outputs a high-level signal (i.e., the liquid level switch is in the open state), the frequency of the signal output by the liquid level switch is recorded. When the frequency of the signal output by the liquid level switch exceeds the first frequency threshold, the environment is determined to be humid.
[0056] The liquid level switch outputs high and low level signals in real time. By continuously receiving this signal, the frequency (or period) of the signal can be calculated, which is the opening and closing frequency of the liquid level switch. The first frequency threshold is the upper limit threshold of the frequency at which dehumidification needs to be activated. The first frequency threshold can be preset experimentally.
[0057] The above steps enable a relatively accurate detection of ambient humidity levels in cooling mode.
[0058] In cooling mode, when the frequency of the signal output by the liquid level switch exceeds the upper threshold of the frequency required to activate dehumidification, the air conditioner can automatically enter dehumidification mode after determining that the environment is humid, thus achieving intelligent control of the air conditioner. After entering dehumidification mode, when the frequency of the signal output by the liquid level switch falls below the lower threshold of the frequency at which dehumidification can be deactivated, the air conditioner can automatically exit dehumidification mode and switch back to cooling mode after determining that the environmental humidity level is suitable.
[0059] (2) In dehumidification mode, when the frequency of the signal output by the level switch exceeds the first frequency threshold and remains stable or increases, it is determined that the ambient humidity is severe, and the air conditioner is controlled to maintain dehumidification mode; when the frequency of the signal output by the level switch decreases to below the second frequency threshold, it is determined that the ambient humidity is suitable, and the air conditioner is controlled to exit dehumidification mode; wherein, the first frequency threshold is greater than the second frequency threshold, and the second frequency threshold is the lower limit threshold for exiting dehumidification, which can be preset experimentally. Through the above steps, the ambient humidity can be detected relatively accurately in dehumidification mode, and intelligent control of the air conditioner can be performed.
[0060] When the air conditioner is first turned on, if the user manually selects dehumidification mode or it defaults to dehumidification mode upon startup, the liquid level switch only begins its detection. In dehumidification mode, to achieve better dehumidification, the air conditioner typically operates at a low airflow. At this time, the temperature of the indoor heat exchanger is lower, making it easier for water vapor in the air to condense into water. If the frequency of the signal output by the liquid level switch is very low, it indicates that the environment is definitely dry. Specifically, determining the ambient humidity level based on the frequency of the liquid level switch's output signal also includes: if the frequency of the signal output by the liquid level switch is lower than a second frequency threshold when the air conditioner immediately enters dehumidification mode after startup, it is determined that the environment is dry, and a reminder to turn off dehumidification mode is output to remind the user to disable it, preventing a direct shutdown of the dehumidification mode and affecting the user experience.
[0061] For example, the level of environmental humidity can be simply categorized as: dry, suitable, humid, and very humid. Of course, humidity levels can also be further subdivided. The humidity level can be preset in the data processing module based on the humidity conditions corresponding to different liquid level switch opening and closing frequencies obtained from experiments.
[0062] In one embodiment, after determining the ambient humidity level based on the current operating mode of the air conditioner and the signal output by the liquid level switch, the method further includes: outputting an ambient humidity level reminder message to inform the user of the current ambient humidity level.
[0063] The method for detecting environmental humidity is described below with reference to a specific embodiment. However, it is worth noting that this specific embodiment is only for better illustration of this application and does not constitute an undue limitation of this application. The same or corresponding terminology as in the above embodiment will not be repeated in this embodiment.
[0064] like Figure 2 As shown, the ambient humidity level can be detected using a level switch 10, a data processing module 20, a display device 30, and a control device 40. The level switch 10 detects the water level inside the air conditioner. The data processing module 20 interacts with the display device 30 to update the air conditioner status, records the detection data from the level switch 10, and outputs signals to the control device 40. The display module 30 displays information and records the air conditioner status. The control device 40 is the control center for the air conditioner's operation.
[0065] The air conditioner's water level detection function is implemented through a switching signal fed back by the level switch 10. When the water level inside the air conditioner reaches the threshold height at which the level switch 10 is activated, the level switch 10 sends a high-level signal to the data processing module 20; when the water level inside the air conditioner drops to the threshold height at which the level switch 10 is deactivated, the level switch 10 sends a low-level signal to the data processing module 20.
[0066] The data processing module 20 performs relevant logic processing based on the high and low level signals fed back by the liquid level switch 10 and the air conditioner's operating mode, and outputs control signals to the control device 40. The control device 40 issues instructions based on the received control signals to cause the air conditioner to perform corresponding actions. The display device 30 displays the current ambient humidity level and dehumidification information.
[0067] First, the air conditioner is turned on, and the liquid level switch detects the water level inside the air conditioner. The data processing module 20 performs different logic processing according to different situations, records the opening and closing frequency of the liquid level switch, and presets an upper limit threshold for the frequency at which dehumidification needs to be turned on (i.e., the first frequency threshold) and a lower limit threshold for the frequency at which dehumidification can be turned off (i.e., the second frequency threshold).
[0068] The data processing module 20 reads the current working mode of the air conditioner from the display device 30, including four modes: air supply, heating, cooling, and dehumidification.
[0069] When the air conditioner is operating in fan mode or heating mode, the liquid level switch 10 remains off and sends a low-level signal. The data processing module 20 determines that the environment is dry and dehumidification is not required. If the liquid level switch 10 is on, the data processing module 20 determines that the environment is humid and outputs a signal to the display device 30 to remind the user that the environment is humid and dehumidification is required.
[0070] When the air conditioner is operating in cooling mode, the liquid level switch 10 is normally closed. The data processing module 20 determines that the environment is very dry, and the display device 30 reminds the user that the environment is dry. If the liquid level switch 10 is open, the data processing module 20 records the opening and closing frequency of the liquid level switch (i.e., the frequency of the signal output by the liquid level switch). When the opening and closing frequency of the liquid level switch exceeds the upper limit threshold of the frequency required to activate dehumidification, it is determined that the environment is humid, and the air conditioner automatically enters dehumidification mode. The display device 30 displays that the air conditioner has entered dehumidification mode. When the opening and closing frequency of the liquid level switch is lower than the lower limit threshold of the frequency at which dehumidification can be exited, it is determined that the humidity level of the environment is suitable, and the air conditioner automatically exits dehumidification mode and switches back to cooling mode. The display device 30 displays that the air conditioner has entered cooling mode.
[0071] When the air conditioner is operating in dehumidification mode, if it enters dehumidification mode immediately upon startup (e.g., when the user manually switches to dehumidification mode or it defaults to dehumidification mode upon startup), the liquid level switch only begins its detection process. In dehumidification mode, to achieve better dehumidification, the air conditioner typically operates at a low airflow. This results in a lower temperature in the indoor heat exchanger, making it easier for water vapor in the air to condense. If the frequency of the signal output by the liquid level switch is very low at this time, it indicates that the environment is definitely dry. In other words, if the air conditioner enters dehumidification mode immediately upon startup, and the frequency of the liquid level switch's opening and closing is lower than the lower threshold for exiting dehumidification, it indicates that the environment is very dry, and the display device 30 reminds the user to turn off the dehumidification mode.
[0072] After the air conditioner has been running in dehumidification mode for a period of time, if the frequency of the liquid level switch opening and closing exceeds the upper limit threshold of the frequency required to turn on dehumidification and the frequency remains stable or increases, it is determined that the environment is particularly humid and the air conditioner should continue to dehumidify. When the frequency of the liquid level switch opening and closing decreases to below the lower limit threshold of the frequency at which dehumidification can be turned off, it is determined that the humidity level of the environment is suitable and the air conditioner should turn off dehumidification mode.
[0073] In summary, for the four common operating modes of an air conditioner, there are three dehumidification judgment scenarios:
[0074] Scenario 1: When the air conditioner is heating or blowing air, the liquid level switch can be turned on to determine that the environment is humid;
[0075] Scenario 2: When the air conditioner is cooling, the liquid level switch is normally closed, which indicates that the environment is dry; if the liquid level switch is open, the data processing module synchronously records the opening and closing frequency of the liquid level switch, and the humidity of the environment can be determined by the speed of the liquid level switch's operation.
[0076] Scenario 3: When the air conditioner is dehumidifying, the data processing module can determine the ambient humidity based on the opening and closing frequency of the liquid level switch, and simultaneously determine whether the ambient humidity level is suitable when the air conditioner is dehumidifying.
[0077] This embodiment does not require a humidity sensor. Based on the existing water level detection function of the air conditioner, the humidity level of the environment is determined by the opening and closing frequency of the liquid level switch and the working mode of the air conditioner. The humidity level detection function can be realized without increasing the cost of the components. Furthermore, the air conditioner's display device can interact with the humidity level information and dehumidification information.
