Drawings
The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
fig. 1 is a flowchart of a control method of a window machine according to an embodiment of the present invention.
Detailed Description
An embodiment of the present invention is described in detail below, the embodiment described with reference to the drawings is exemplary, and a control method of a window machine according to an embodiment of the present invention is described below with reference to fig. 1.
The control method of the window machine according to the embodiment of the invention, as shown in fig. 1, comprises the following steps:
and S1, the window machine enters a mute mode.
And S2, opening a drain valve of a water filling groove of the window machine.
When the user selects the window machine to execute the mute mode, the drain valve is opened. When the window machine works, the condensed water can continuously enter the water beating tank so as to enable the water level of the water beating tank to rise, however, the drainage speed of the water beating tank can be larger than the speed of the condensed water flowing into the water beating tank by opening the drain valve so as to enable the water level of the water beating tank to fall. For example, the drain valve sets up in the low water level department of the basin of fetching water, can realize the drainage and the retaining of the basin of fetching water through opening and closing of control drain valve to this realizes the control to the water level height in the basin of fetching water. Preferably, the bottom region of scupper is located to the drain valve, and the water of being convenient for in the scupper can continue to flow via the drain valve, and then reduces the water yield in the scupper, reduces the water level in the scupper promptly, and wherein, the decline of the water level of scupper makes the sound of beating water of the wheel of beating water also can descend thereupon, and then so set up the sound that can reduce the wheel of beating water.
S3, detecting a first actual water level of the watering trough;
s4, judging whether the first actual water level is less than or equal to the mute limit water level;
and S5, when the judgment result in the step S4 is positive, reducing the frequency of the compressor of the window machine, and reducing the rotating speed of the indoor fan of the window machine.
The water level in the water fetching groove is detected to start to continuously descend after the drain valve is opened, then whether the first actual water level is smaller than or equal to the mute limit water level or not is judged, if the first actual water level is smaller than or equal to the mute limit water level, the first actual water level is shown to meet the water level requirement of the mute mode, at the moment, the frequency of the compressor and the rotating speed of the indoor fan are reduced again, and the situation that the water fetching sound is obvious after the compressor directly reduces the frequency and the rotating speed of the fan directly reduces after the compressor enters the mute mode is prevented from occurring.
The water fetching sound is related to the height of the water level of the water fetching groove, and the water fetching sound is reduced along with the reduction of the water level. The mute limit water level is: when the window machine enters the mute mode, when the mute mode runs at the corresponding compressor frequency and the corresponding fan rotating speed, and when the actual water level is less than or equal to the mute limit water level, the water beating sound is very small and cannot be heard by the compressor running sound and the air supply sound, and the water beating sound is understood to be 'disappeared'. It should be noted that, when the water level is at the mute limit, the water turbine can still pump water to improve the operation energy efficiency of the whole machine, and the water pumping sound of the water turbine is minimum at this time.
After the window machine enters the mute mode, the drain valve is opened firstly to reduce the water level in the water beating tank so as to reduce the water beating sound of the water beating wheel, then the first actual water level is detected in real time, and when the first actual water level is smaller than or equal to the mute limit water level, the frequency of the compressor and the rotating speed of the indoor fan are reduced, and the frequency of the compressor and the rotating speed of the indoor fan meet corresponding preset values in the mute mode. The window machine that so sets up can reduce the noise that the window machine produced when the silence mode when satisfying the refrigeration demand of window machine, does benefit to improvement user's use and experiences.
According to the control method of the window machine, after the window machine enters a mute mode, the water level in the water pumping groove can be reduced by opening the drain valve, the water in the water tank is discharged to be reduced to be below the mute limit water level before the frequency reduction rate of the compressor and the rotating speed of the wind gear are reduced, then the frequency of the compressor of the window machine and the rotating speed of the indoor fan of the window machine are reduced, and the water pumping sound is far smaller than the running sound of the compressor after frequency reduction and the air supply sound of the fan after speed reduction, so that the water pumping sound is not obvious, the user experience is improved, meanwhile, the water level in the water pumping groove is controlled, and the water pumping effect can be kept.
In some embodiments, as shown in fig. 1, after step S5, the method further includes:
s61, detecting a second actual water level of the watering trough;
s62, judging whether the second actual water level is less than or equal to the effective water fetching water level, wherein the effective water fetching water level is lower than the mute limit water level;
s63, when the judgment result in the step S62 is yes, closing the drain valve;
s64, when the determination result in step S62 is no, the process returns to step S61.
The water pumping effect of the water pumping wheel is very weak and the water pumping effect is very poor when the water level in the water pumping groove is reduced to a certain height, so that the energy efficiency of the whole machine is not promoted, and the water level height corresponding to the critical point is called as an effective water pumping level.
The drain valve of the water beating tank of the window machine is opened so that the first actual water level is less than or equal to the mute limit water level, and after the frequency of the compressor and the rotating speed of the indoor fan are reduced, the second actual water level of the water beating tank is detected, whether the second actual water level is less than or equal to the effective water beating level is judged, if the second actual water level is less than or equal to the effective water beating level, the drain valve is controlled to be closed, the water level in the water beating tank cannot continue to fall at the moment, the condensate water can continuously enter the water beating tank so that the water level rises, therefore, the water beating tank can be guaranteed to beat, and the window machine is guaranteed to still be capable of utilizing the condensate water to improve the operation energy efficiency of the whole machine.
From this, through the actual water level of real-time detection second, can be when window machine operation silence mode, can prevent that the water level in the water fetching groove is low excessively, and lead to the unable problem that promotes the operation efficiency of complete machine of fetching water, and when the water level in the water fetching groove is low excessively, in time close the drain valve, and then make the water level in the water fetching groove no longer reduce, thereby be convenient for control to fetch the actual water level of groove and be located between silence limit water level and the effective water level of fetching water, and then guarantee the refrigeration effect of window machine, do benefit to reinforcing user's use and experience.
More specifically, as shown in fig. 1, after step S63, the method further includes:
s71, detecting a third actual water level of the watering trough;
s72, judging whether the third actual water level is greater than the mute limit water level or not;
s73, when the judgment result in the step S72 is yes, the drainage valve is opened;
s74, when the determination result in step S72 is no, the process returns to step S71.
After closing the drain valve, the third actual water level of real-time detection scuttle, and judge whether the third actual water level is greater than silence limit water level, if the third actual water level is greater than silence limit water level, it is great to explain the noise that present water fetching wheel was watered, at this moment, reopen the drain valve and then can reduce the noise of water fetching wheel in order to reduce the water level, if third actual water level less than or equal to silence limit water level, it is less to explain the noise that present water fetching wheel was watered, at this moment, the size of noise accords with the requirement of silence mode, need not to open the drain valve, and last the third actual water level to scuttle detects.
From this, through real-time detection third actual water level, prevent to beat the water level in the basin too high and produce too big noise, and can in time reduce its water level through opening the drain valve when the water level of beating the basin is too high, and then the noise when guaranteeing window machine operation silence mode is less, does benefit to the use that improves the user and experiences.
As shown in fig. 1, after step S73, the method further includes:
s81, judging whether the window machine is switched to other modes;
s82, when the judgment result in the step S81 is yes, ending the mute mode, closing the drain valve and operating the window machine in other modes;
s83, when the determination result in step S81 is no, the process returns to step S61.
And when the window machine runs in the mute mode, judging whether the window machine is switched to other modes, if so, restraining the mute mode and closing the drain valve so that the window machine can run in other modes. If the window machine continues to operate in the silent mode, the current water level is re-detected, and the subsequent control method is continuously executed, which is not described herein again.
From this, through judging whether the user has the demand of the motion mode of switching the window machine, and closing of in time control drain valve to avoid the drain valve to open and produce the influence to other modes of window machine, guarantee that the window machine can be with other modes normal operating, thereby the user can switch the operation mode of window machine according to actual demand, and then the window machine has multiple operation mode, does benefit to the user demand that satisfies the user.
In some embodiments, as shown in fig. 1, after step S4, the method further includes:
s5, when the determination result in step S4 is no, the process returns to step S3. That is, when the first actual water level is higher than the mute limit water level, it indicates that the water level in the watering trough is too high, at this time, because the water in the watering trough continuously flows out through the drain valve, the water level in the watering trough continuously decreases, the first actual water level is continuously detected, whether the first actual water level is lower than the mute limit water level is determined, until the first actual water level is lower than or equal to the mute limit water level, and step S5 is executed. Therefore, the first actual water level is continuously detected, the first actual water level can be prevented from being too high, noise is effectively reduced, and the control precision of the control method of the window air conditioner is improved.
In some embodiments, the step S3 of detecting the first actual water level of the watering trough is realized by a water level detecting device.
The water level detection device is used for detecting the height of the water level in real time and is in communication connection with the drain valve, so that the water level detection device can directly control the switch of the drain valve. Therefore, the accuracy of detection of the water level detection device can be guaranteed, the opening and closing difficulty of the drain valve is reduced, and the precision is high.
In other embodiments, the opening and closing of the drain valve is achieved by whether the mute limit water level switch and the effective flush water level switch are actuated, the effective flush water level switch being located below the mute limit water level switch, wherein the drain valve is closed when the effective flush water level switch is actuated, and the drain valve is opened when the mute limit water level switch is actuated.
Silence limit water level switch and the water level switch of effectively fetching water all locate on the water fetching groove, and silence limit water level switch and the water level switch of effectively fetching water all are used for opening or closing of control drain valve, wherein, after the window machine gets into the silence mode and when first actual water level is greater than silence limit water level, silence limit water level switch is opened in order to open the drain valve, and then reduce the actual water level in the water fetching groove, when the second actual water level that other modes of window machine operation or water fetching groove are less than when effectively fetching water the water level, effectively fetch water level switch and open in order to close the drain valve, and then make the water level in the water fetching groove can rise.
From this, through setting up silence limit water level switch and the water level switch of effectively fetching water, can control opening and closing the drain valve respectively according to the operation mode of window machine and the actual water level of fetching the basin to the actual water level of control fetching the basin is located silence limit water level and effectively fetches water between the water level, when guaranteeing to fetch water the efficiency, can reduce the noise that the window machine produced when the silence mode, does benefit to the use that improves the user and experiences.
In still other embodiments, the opening and closing of the drain valve is realized by a mute limit water level switch and a timer, when the mute limit water level switch acts, the drain valve is opened, the timer starts to time after the drain valve is opened, and when the timing time of the timer reaches the preset time, the drain valve is closed.
Specifically, after the window air conditioner enters the mute mode and when the first actual water level is greater than the mute limit water level, the mute limit water level switch controls the drain valve to be opened, so that the actual water level in the water feeding groove is reduced, and when the window air conditioner runs in other modes or the timing time of the timer reaches the preset time, the mute limit water level switch controls the drain valve to be closed, so that the water level in the water feeding groove can be increased.
Wherein, the predetermined time refers to: when the water level of the water fetching groove is at the mute limit water level, the drain valve is opened to drain water, and the water level of the water fetching groove is reduced to the time required by the effective water fetching water level.
From this, through setting up silence limit water level switch and time-recorder, can be after predetermined time through the closing of silence limit water level switch control drain valve to the actual water level of the control of being convenient for scuttle is located the silence limit water level and effectively scuttle between the water level, and then can reduce the noise that the window machine produced when the silent mode when satisfying the refrigeration demand of window machine, does benefit to the use that improves the user and experiences.
