[0040] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0041] Example 1

[0042] like Figure 1 As shown, this embodiment provides an automatic water changing method for an air-conditioning humidifier, comprising:

[0043] S1: Detect whether a humidification instruction is received, and if so, turn on the humidifier; wherein the humidifier is located below the air outlet of the air conditioner.

[0044] S2: Start the timer to record the humidification time.

[0045] S3: Detecting the current water level of the water tank in the humidifier, and if the current water level is higher than the minimum water level, comparing the humidification time with a humidification time threshold.

[0046] S4: If the humidification time is greater than or equal to the humidification time threshold, water is automatically added to the water tank in the humidifier through a water inlet pipe.

[0047] The controller is connected to the humidifier by wire or wirelessly. If the wired connection is adopted, the controller and the humidifier are electrically connected by wire; if the wireless connection is adopted, a first wireless module is set in the humidifier, and a second wireless module is set in the controller. The first wireless module and the second wireless module are connected by WIFI or Bluetooth. The humidifier uses the first wireless module to send the current water level of the water tank to the second wireless module, and the humidifier uses the first wireless module to receive the control instructions sent by the second wireless module. The control instructions include starting the humidifier, shutting down the humidifier, and adding water to the humidifier.

[0048] The humidifier is set below the air outlet of the air conditioner so that the air outlet of the humidifier is set opposite to the air outlet of the air conditioner. During operation, the humidifier converts liquid water into water vapor, and the water vapor is emitted upward to the air outlet of the air conditioner. The wind sent out from the air outlet of the air conditioner takes away the water vapor, which can increase the water vapor content of the wind sent out from the air outlet of the air conditioner, thereby increasing the humidity of the indoor environment.

[0049] When the humidifier is turned on, start the timer, record the start time and current time, and the current time minus the start time is the humidification time. Set the humidification time threshold. When the humidification time is equal to the humidification time threshold, the amount of humidification water consumed in the humidifier water tank is fixed because the power of the humidifier is constant. When the humidifier works at the humidification time threshold, the current water level of the remaining humidification water in the water tank is higher than the minimum water level.

[0050] The current water level of the water tank in the humidifier is detected at a preset time interval, such as 1 second. If the current water level is higher than the minimum water level, the humidification time is compared with the humidification time threshold to determine whether the trigger condition of the water addition method using the timer timing is met.

[0051] The two ends of the water inlet pipe are connected to the water inlet of the water tank in the humidifier and the water supply device respectively. If the humidification time is greater than or equal to the humidification time threshold, it means that the triggering condition of the water adding method using the timer is met, and at this time, the water inlet pipe is used to automatically add water to the water tank in the humidifier.

[0052] The automatic water changing method of the air conditioner humidifier of this embodiment includes detecting whether a humidification instruction is received, and if so, turning on the humidifier; wherein the humidifier is located below the air outlet of the air conditioner. After the humidifier is started, the liquid water in the water tank is converted into gaseous water vapor, and the water vapor is blown upward and diffused to the air outlet of the air conditioner, so that the wind blown out from the air outlet of the air conditioner carries water vapor, thereby increasing the humidity of the indoor environment. Start the timer and record the humidification time. During the humidification process of the humidifier, as the liquid water is converted into gaseous water vapor, the liquid level of the water tank in the humidifier continues to decrease. Detect the current water level of the water tank in the humidifier. If the current water level is higher than the minimum water level, compare the humidification time with the humidification time threshold. If the humidification time is greater than or equal to the humidification time threshold, it means that the water consumption of the water tank in the humidifier is large and the remaining water in the water tank in the humidifier is insufficient. At this time, the water inlet pipe is used to automatically add water to the water tank in the humidifier. The present invention combines two methods, timer timing and liquid level detection. The premise of using the timer timing method is that the current water level is higher than the minimum water level, and the premise of using the liquid level detection method is that the current water level is lower than or equal to the current water level. The trigger conditions of the two detection methods are different. Therefore, it is possible to prevent control confusion caused by adding water to the water tank using two detection methods at the same time. The timer timing method can also be used to add water to the water tank in advance when the current water level is higher than the minimum water level, thereby achieving timely water addition, improving the humidification efficiency of the humidifier, and preventing scale or ions in the lower layer of the water tank from diffusing to the upper layer of the water tank. When the timer fails and the current water level is lower than or equal to the minimum water level, the water inlet pipe is used to add water to the water tank in the humidifier to prevent the low liquid level in the water tank from affecting the humidification effect of the humidifier.

[0053] Example 2

[0054] like Figure 1 As shown, this embodiment provides an automatic water changing method for an air-conditioning humidifier, comprising:

[0055] S1: Detect whether a humidification instruction is received, and if so, turn on the humidifier; wherein the humidifier is located below the air outlet of the air conditioner.

[0056] S2: Start the timer and record the humidification time.

[0057] S3: Detecting the current water level of the water tank in the humidifier, and if the current water level is higher than the minimum water level, comparing the humidification time with a humidification time threshold.

[0058] S4: If the humidification time is greater than or equal to the humidification time threshold, water is automatically added to the water tank in the humidifier through a water inlet pipe.

[0059] After comparing the humidification time with the humidification time threshold, the method further includes:

[0060] S41': If the humidification time is less than the humidification time threshold, the timer continues to count.

[0061] S42': Detect whether a water adding event is triggered, and if so, automatically add water to the water tank in the humidifier through a water inlet pipe.

[0062] If the humidification time is less than the humidification time threshold, it means that the humidification time of the humidifier is short, the amount of humidification water consumed in the water tank of the humidifier is small, and the remaining humidification water in the water tank of the humidifier is large. At this time, the current water level in the water tank is higher than the minimum water level, and the timer continues to count.

[0063] The water adding event includes that the humidification time is greater than or equal to the humidification time threshold, and the current water level is lower than or equal to the minimum water level. If the water adding event is triggered, that is, when the timer is working normally, the humidification time is greater than or equal to the humidification time threshold, since the power of the humidifier is constant, it means that the working time of the humidifier has reached the critical value, and the amount of humidification water in the water tank is insufficient. At this time, open the valve of the water inlet pipe, and the humidification water flows into the water tank of the humidifier through the water inlet pipe to replenish the humidification water in the water tank of the humidifier. In the case of a timer failure, the humidification time cannot be recorded, and the current water level in the water tank is detected. If the current water level is lower than or equal to the minimum water level, it means that the amount of humidification water in the water tank is insufficient. At this time, the same water adding method as the timer water replenishment is adopted, which will not be repeated here.

[0064] After detecting the current water level of the water tank in the humidifier, the method further includes:

[0065] S43': If the current water level is lower than or equal to the minimum water level, water is automatically added to the water tank in the humidifier through a water inlet pipe.

[0066] After the timer starts, if the current water level is detected to be lower than or equal to the minimum water level during the first detection, it means that the remaining humidification water in the water tank of the humidifier is insufficient after the humidifier was used last time. At this time, the water inlet pipe is used to automatically add water to the water tank in the humidifier.

[0067] After comparing the humidification time with the humidification time threshold, the embodiment of the present invention also includes that if the humidification time is less than the humidification time threshold, the timer continues to time. Detect whether a water adding event is triggered. If so, the water inlet pipe is used to automatically add water to the water tank in the humidifier. The water adding event includes that the humidification time is greater than or equal to the humidification time threshold, and the current water level is lower than or equal to the minimum water level. When the timer is working normally, the humidification time is greater than or equal to the humidification time threshold. Since the power of the humidifier is constant, it means that the working time of the humidifier has reached the critical value, and the amount of humidification water in the water tank is insufficient. At this time, the valve of the water inlet pipe is opened, and the humidification water flows into the water tank of the humidifier through the water inlet pipe to replenish the amount of humidification water in the water tank of the humidifier. In the case of a timer failure, the humidification time cannot be recorded. The current water level in the water tank is detected. If the current water level is lower than or equal to the minimum water level, it means that the amount of humidification water in the water tank is insufficient. At this time, the same water adding method as the timer timing water replenishment is used.

[0068] Example 3

[0069] like Figure 1 As shown, this embodiment provides an automatic water changing method for an air-conditioning humidifier, comprising:

[0070] S1: Detect whether a humidification instruction is received, and if so, turn on the humidifier; wherein the humidifier is located below the air outlet of the air conditioner.

[0071] S2: Start the timer to record the humidification time.

[0072] S3: Detecting the current water level of the water tank in the humidifier, and if the current water level is higher than the minimum water level, comparing the humidification time with a humidification time threshold.

[0073] S4: If the humidification time is greater than or equal to the humidification time threshold, water is automatically added to the water tank in the humidifier through a water inlet pipe.

[0074] like Figure 3 As shown, before the detection of whether a humidification instruction is received, the method further includes:

[0075] S11': Detect whether the air conditioner is in a heating mode, and if so, detect environmental parameters; wherein the environmental parameters include ambient temperature and ambient humidity.

[0076] S12': Send the environmental parameters to the user terminal.

[0077] S13': Prompt the user whether to turn on the humidifier.

[0078] The air conditioner is equipped with a temperature sensor and a humidity sensor. When the temperature is low in winter, after the user turns on the heating mode of the air conditioner, the temperature sensor is used to collect the ambient temperature of the indoor environment, and the humidity sensor is used to collect the ambient humidity of the indoor environment.

[0079] The air conditioner is also provided with a third wireless module, which is wirelessly connected to a user terminal, which can be a mobile phone or a computer, and is not limited here. The third wireless module sends the collected ambient temperature and ambient humidity to the user terminal, and pops up a prompt interface on the display screen of the user terminal, or issues a voice prompt on the user terminal to prompt the user whether to turn on the humidifier. The user clicks on the control option according to the prompt content, and the user terminal sends the user instruction corresponding to the control option to the first wireless module of the humidifier.

[0080] After prompting the user whether to turn on the humidifier, the method further includes:

[0081] S14': receiving a user instruction returned by the user terminal; wherein the user instruction includes the humidification instruction and the standby instruction.

[0082] S15': If the received user instruction is the standby instruction, control the humidifier to enter the standby state.

[0083] S16': Detect whether the humidification instruction is received, and if received, control the humidifier to switch from the standby state to the working state.

[0084] S17': If the received user instruction is the humidification instruction, control the humidifier to perform humidification.

[0085] Step S17' is parallel to step S15'. After the humidifier executes step S14', it executes steps S15'-S16', or executes step S17'.

[0086] Before the detection of whether the humidification instruction is received in this embodiment, it also includes detecting whether the air conditioner is in heating mode. If so, detecting environmental parameters; wherein the environmental parameters include ambient temperature and ambient humidity. The environmental parameters are sent to the user terminal to prompt the user whether to turn on the humidifier. After the prompting of the user whether to turn on the humidifier, it also includes receiving a user instruction returned by the user terminal; wherein the user instruction includes the humidification instruction and the standby instruction. After receiving the user instruction returned by the user terminal, it also includes controlling the humidifier to enter the standby state if the received user instruction is the standby instruction. Detecting whether the humidification instruction is received, if received, controlling the humidifier to switch from the standby state to the working state. A third wireless module is also provided in the air conditioner, and the third wireless module is wirelessly connected to the user terminal. The third wireless module sends the collected ambient temperature and ambient humidity to the user terminal, and pops up a prompt interface on the display screen of the user terminal, or issues a voice prompt on the user terminal to prompt the user whether to turn on the humidifier. The user clicks the control option according to the prompt content, and the user terminal sends the user instruction corresponding to the control option to the first wireless module of the humidifier.

[0087] Example 4

[0088] like Figure 1 As shown, this embodiment provides an automatic water changing method for an air-conditioning humidifier, comprising:

[0089] S1: Detect whether a humidification instruction is received, and if so, turn on the humidifier; wherein the humidifier is located below the air outlet of the air conditioner.

[0090] S2: Start the timer to record the humidification time.

[0091] S3: Detecting the current water level of the water tank in the humidifier, and if the current water level is higher than the minimum water level, comparing the humidification time with a humidification time threshold.

[0092] S4: If the humidification time is greater than or equal to the humidification time threshold, water is automatically added to the water tank in the humidifier through a water inlet pipe.

[0093] like Figure 2 As shown, after comparing the humidification time with the humidification time threshold, the method further includes:

[0094] S41': If the humidification time is less than the humidification time threshold, the timer continues to count.

[0095] S42': Detect whether a water adding event is triggered, and if so, automatically add water to the water tank in the humidifier through a water inlet pipe.

[0096] The water adding event includes that the humidification time is greater than or equal to the humidification time threshold, and the current water level is lower than or equal to the lowest water level.

[0097] After detecting the current water level of the water tank in the humidifier, the method further includes:

[0098] If the current water level is higher than the maximum water level, the water inlet pipe valve is closed, and the water inlet pipe is stopped from automatically adding water to the water tank in the humidifier.

[0099] If the current water level is higher than the maximum water level, it means that there is too much humidification water in the water tank of the humidifier. The humidifier may generate more water vapor during humidification, and the water vapor will spray outward instead of diffusing outward, resulting in poor humidification effect. Therefore, when the current water level is higher than the maximum water level, close the water pipe valve and stop adding water to the water tank in the humidifier. Preferably, the side wall of the water tank in the humidifier is also connected to a water outlet pipe. Open the valve of the water outlet pipe to discharge the humidification water in the water tank in the humidifier to reduce the current water level to the maximum water level.

[0100] After the detection of whether a water adding event is triggered, the method further includes:

[0101] S44': If the humidification time is equal to the humidification time threshold, determining that the current water level is a critical water level; wherein the critical water level is higher than the lowest water level and lower than the highest water level.

[0102] S45': according to the height difference between the highest water level and the critical water level, adding humidifying water in an amount corresponding to the height difference into the water tank in the humidifier.

[0103] The critical water level is between the minimum water level and the maximum water level. By setting the critical water level corresponding to the humidification time threshold, a certain height margin can be reserved so that the water inlet pipe is opened before the current water level of the water tank in the humidifier drops to the minimum water level, and water is added to the water tank in the humidifier in time.

[0104] Subtract the critical water level from the highest water level to get a fixed height difference. You can use a uniform water adding method or a variable speed water adding method. If the uniform water adding method is used, set the water adding time, divide the height difference by the water adding time to get the water adding speed. If the variable speed water adding method is used, set the maximum water adding speed, start with a water adding speed of 0, increase the water adding speed at a constant first acceleration until the water adding speed reaches the maximum water adding speed, and then start from the maximum water adding speed, reduce the water adding speed at a constant second acceleration until the water adding speed is equal to 0. The first acceleration is greater than 0, and the second acceleration is less than 0. The first acceleration and the second acceleration may be equal or unequal, and are not limited here.

[0105] like Figure 4As shown, after the water inlet pipe is used to automatically add water to the water tank in the humidifier, it also includes:

[0106] S51: If the current water level is higher than the lowest water level and lower than or equal to the highest water level, start the ultrasonic transmitter.

[0107] S52: using the ultrasonic transmitter to atomize the humidification water on the upper part of the water tank, so as to deliver the atomized water vapor to the air outlet of the air conditioner.

[0108] The ultrasonic transmitter is installed on the side of the water tank of the humidifier. The water quality of the humidification water in the upper layer of the water tank is good, while the water quality of the humidification water in the lower layer of the water tank is poor. The humidification water in the lower layer may contain harmful substances and / or scale. The ultrasonic transmitter is used to aim at the humidification water in the water tank and emit ultrasonic waves to drive the liquid humidification water to vibrate, so that the temperature of the liquid humidification water increases and turns into water vapor.

[0109] The water vapor is blown upward from the air outlet of the humidifier until the water vapor diffuses to the vicinity of the air outlet of the air conditioner, so that the air sent out from the air outlet of the air conditioner contains more water vapor, thereby increasing the humidity of the indoor environment. The present invention does not need to use a water pump to pump humidified water to the air outlet of the air conditioner. The humidifier can generate relatively uniform water vapor, so that the air sent out from the air outlet of the air conditioner contains water vapor with a stable content.

[0110] After the detection of whether the water adding event is triggered in this embodiment, it also includes determining that the current water level is a critical water level if the humidification time is equal to the humidification time threshold; wherein the critical water level is higher than the lowest water level and lower than the highest water level. According to the height difference between the highest water level and the critical water level, the amount of humidification water corresponding to the height difference is added to the water tank in the humidifier. After the water inlet pipe is used to automatically add water to the water tank in the humidifier, it also includes starting the ultrasonic transmitter if the current water level is higher than the lowest water level and lower than or equal to the highest water level. The ultrasonic transmitter is used to atomize the humidification water on the upper part of the water tank to send the atomized water vapor to the air outlet of the air conditioner. The critical water level is subtracted from the highest water level to obtain a fixed height difference. The water can be added at a uniform speed or at a variable speed. The ultrasonic transmitter is installed on the side of the water tank of the humidifier. The water quality of the humidified water in the upper layer of the water tank is good, while the water quality of the humidified water in the lower layer of the water tank is poor. The humidified water in the lower layer may contain harmful substances and / or scale. The ultrasonic transmitter is aimed at the humidified water in the water tank to emit ultrasonic waves to drive the liquid humidified water to vibrate, so that the temperature of the liquid humidified water increases and turns into water vapor. The humidifier equipped with an ultrasonic transmitter can produce more uniform water vapor, so that the air sent out from the air outlet of the air conditioner contains a stable amount of water vapor.
