As shown in Figure 1, illustrate the present invention based on the structure of humidifying air conditioner one embodiment.In this embodiment, humidifying air conditioner is on-hook, but humidifying air conditioner of the present invention is not limited to on-hook, is also applicable to cabinet-type air conditioner, mobile air conditioner etc.This humidifying air conditioner comprises housing 10 and is arranged on indoor heat exchanger 20, blower fan 30 and the electric-controlled box 40 in housing 10.Wherein indoor heat exchanger 20 top is provided with guiding gutter 21, and the bottom of this guiding gutter 21 is provided with aperture 211.This guiding gutter 21 is communicated with by the water tank 50 of aqueduct 80 with housing 10 outside, is provided with water pump 51 in water tank 50, and this water pump 51 is connected with aqueduct 80.Also be provided with filter 52 in water tank 50, water tank 50 is divided into first area 501 and second area 502, and water pump be arranged in first area 501.Be provided with division board accepting groove inside water tank 50, removably insert described filter septum accepting groove to make filter septum 52.The bottom of indoor heat exchanger 20 is provided with drip tray 60, and this drip tray 60 is communicated with water tank 50 by aqueduct 90.If be provided with filter septum 52 in water tank 50, then the water in drip tray 60 drains in the second area of water tank 50 by aqueduct 90.
In above-mentioned humidifying air conditioner, by water pump 51 by the water in water tank 50 by aqueduct 80 suction guiding gutter 21, and flow to the surface of indoor heat exchanger 20 by the aperture 211 of guiding gutter 21, current along indoor heat exchanger 20 fin current and under, flow in drip tray 60.Then the water of drip tray 60 is back to water tank 50 by aqueduct 90 and circulates.In the process that current flow in indoor heat exchanger 20 surface circulation, air by the outside suction casing 10 of housing 10, and after indoor heat exchanger 20, is blowed to indoor by blower fan 30.Therefore, blowing in indoor air and with aqueous vapor, the humidification function of air-conditioner will achieved.
In above-mentioned humidifying air conditioner, be also provided with osculum 53 and overfolw hole 54 in the second area 502 of water tank 50, wherein osculum 53 is arranged on the bottom of water tank 50, to be discharged by the water in water tank 50 by drainpipe; Overfolw hole 54 is arranged on the sidewall of water tank 50, is also discharged by the water exceeding the high water level of water tank 50 by drainpipe, overflows described water tank 50 with the water in caisson 50.Wherein, osculum 53 is provided with type of tamper evidence, can be flowed in the first area 501 of water tank 50 to make the water be back in the second area 502 of water tank 50 by filter septum 52.When needing the water in second area 502 to discharge, then type of tamper evidence can be decontroled.Be understandable that, the drainpipe that also can be communicated with at osculum 53 be provided with magnetic valve, discharged by osculum 53 with the water controlled in water tank 50.
The embodiment of the present invention, when needs start humidification, first judges humidification type, then starts different air-conditioner patterns according to humidification type, then open water pump.Therefore, the embodiment of the present invention not only achieves humidification function, but also meets different humidification requirements.
Based on above-mentioned humidifying air conditioner, the present invention proposes a kind of control method of humidifying air conditioner.As shown in Figure 2, the control method of this humidifying air conditioner comprises the following steps:
Step S110, when detecting humidification instruction, determine the humidification type that humidification instruction is corresponding;
When user triggers humidification function by remote controller or humidifying air conditioner control panel, the electric-controlled box of humidifying air conditioner will detect humidification instruction.Now, will judge the humidification type that humidification instruction is corresponding, this humidification type can comprise normal humidification, powerful humidification, automatic humidification etc.Certainly, also by increasing by a humidification decision circuitry in electric-controlled box 50, by obtaining the current humidity of room air, and current humidity and target humidity can be compared, to judge whether to start humidification function.To carry out humidification, then produce humidification instruction, the humidification type of this humidification instruction acquiescence is automatic humidification.
Step S120, according to determined humidification type, control described air-conditioner and operate in the pattern corresponding to described humidification type;
When determined humidification type is normal humidification, controls described air-conditioner and remain on current operational mode.Such as, if when current operating modes of air conditioner is refrigeration mode, keeps the operational mode of current air-conditioner constant, start humidification function simultaneously, namely start water pump 51.
When determined humidification type is powerful humidification, controls described air-conditioner and switch to heating mode by current operational mode.Such as, if when current operating modes of air conditioner is refrigeration mode, controls air-conditioner and switch to heating mode by refrigeration mode, to promote the temperature on indoor heat exchanger surface.Start humidification function, namely start water pump 51, water extracts to heat exchanger top by water pump 51 from water tank, and flow to bottom it from heat exchanger top through heat exchanger simultaneously.The temperature on indoor heat exchanger surface raises, and will accelerate the evaporation of water on indoor heat exchanger surface, thus improves the humidity of the air through indoor heat exchanger surface, and then improve the humidity of room air.Due under powerful humidifying mode, air-conditioner be controlled and switch to heating mode, if the pattern before air-conditioner switching is just heating mode, then not need to switch.If the pattern before air-conditioner switches is refrigeration mode, and when now switching to heating mode for a long time, will affect the comfort level of user, therefore a period of time after switching to heating mode by refrigeration mode, heating mode is switched back refrigeration mode.Or after switching to heating mode by refrigeration mode, by real-time sensing chamber humidity, if indoor humidity reaches desired value, then switch back refrigeration mode.
When determined humidification type is automatic humidification, detects current humidity and environment temperature, and judge whether current humidity and environment temperature reach humidification entry condition, if reach normal humidification entry condition, then control air-conditioner and start normal humidification; If reach powerful humidified condition, then control air-conditioner and start powerful humidification.If do not reach humidification entry condition, then do not start humidification.This normal humidified condition and powerful humidified condition can be arranged according to specific circumstances.For powerful humidified condition: current humidity value is lower than target humidity value, and the difference of described target humidity value and described current humidity value is greater than preset humidity threshold, and indoor temperature is less than preset temperature threshold value.Such as: current humidity value is less than target humidity value and target humidity value and current humidity value differ by more than 20%RH, environment temperature, lower than 20 DEG C, can open powerful humidification function automatically.
Be understandable that, in order to save humidification power consumption, after startup humidifying mode, incite somebody to action sensing chamber's humidity in real time, if indoor humidity reaches target humidity, then stopping humidification.Or, when air-conditioner receives the humidification halt instruction that user sends, stop humidification.If carried out the switching of operational mode under humidifying mode, then the operational mode before switching back.
Step S130, the water pump controlled in water tank are opened, humidifying air conditioner is entered by pipeline to make the water in water tank, and flow to bottom it by the top of the heat exchanger in humidifying air conditioner through heat exchanger, be then pooled in the drip tray of exchanger base, finally flow back into water tank again.
When starting humidifying mode, the water pump that air-conditioner controls in water tank 50 is opened, thus make the water in water tank 50 enter humidifying air conditioner by pipeline, and by the top downstream of the heat exchanger 20 in humidifying air conditioner down to the bottom of heat exchanger 20, then be pooled in the drip tray 60 bottom heat exchanger 20, finally flow back into water tank 50 again.
Further, as shown in Figure 3, the control method of above-mentioned humidifying air conditioner also can comprise:
The scope Inner eycle increasing or decreasing that step S140, the rotating speed controlling the indoor fan of humidifying air conditioner are being preset.
The water on indoor heat exchanger 20 surface is blown into indoor to prevent the wind speed of blower fan 30 too high, in the present embodiment, when will control humidifying air conditioner startup humidification function, the rotating speed of blower fan 30 will be limited in default scope.And the scope Inner eycle increasing or decreasing that the rotating speed controlling blower fan is being preset, thus make to be blown into indoor wind formation rhythm wind.In addition, this scope preset be in relative maximum speed, low-grade rotating speed and and the following range of speeds.And, be also greater than rotating speed corresponding to indoor fan under normal humidifying mode by arranging rotating speed corresponding to indoor fan under powerful humidifying mode.Such as, if the rotation speed of fan of present mode is high-grade corresponding rotating speed, then when starting powerful humidification, will the rotating speed of wind speed in middle-grade correspondence of air conditioner chamber's inner blower be controlled, and fluctuate up and down centered by the rotating speed of middle-grade correspondence.When starting normal humidification, controlling the wind speed of air conditioner chamber's inner blower at low-grade corresponding rotating speed, and fluctuating up and down centered by low-grade corresponding rotating speed.
Further, above-mentioned air-conditioner not only utilizes water in the flowing of air-condition heat exchanger surface circulation, can realize the humidification function of air-conditioner, but also can realize the cleaning function of indoor heat exchanger.As shown in Figure 4, the control method of above-mentioned humidifying air conditioner also comprises:
Step S210, in water tank, arrange filter septum, water tank is divided into first area and second area, and described water pump is positioned at first area;
In the present embodiment, owing to realizing the cleaning function of indoor heat exchanger, the water of the indoor heat exchanger surface flowing at air-conditioning is contained cleaning agent, the water be then back in water tank 50 is sewage, therefore need to load onto filter septum 52 in water tank 50, so that water tank 50 is divided into first area 501 and second area 502, makes the water being back to water tank 50 after the filtration of filter septum, enter in first area 501 and circulate.
Step S220, detect cleaning heat exchanger instruction, the off-premises station and the indoor fan that control humidifying air conditioner are out of service;
When user triggers heat exchanger cleaning function by remote controller or humidifying air conditioner control panel, the electric-controlled box of humidifying air conditioner will detect the instruction of cleaning heat exchanger.Certainly, also cleaning heat exchanger decision circuitry can be added by increasing in electric-controlled box one, by obtaining the running time of air-conditioner, if when air-conditioner reaches preset time (such as 200 hours) running time, then judge to need to start heat exchanger cleaning function, produce the instruction of cleaning heat exchanger.When electric-controlled box 50 detects cleaning heat exchanger, the off-premises station and the indoor set that control humidifying air conditioner are out of service.
Step S230, the water pump controlled in water tank are opened, humidifying air conditioner is entered by pipeline to make the water of first area in water tank, and flow to bottom it by the top of the heat exchanger in humidifying air conditioner through heat exchanger, then be pooled in the drip tray of exchanger base, finally the second area of reflow tank again.
The water pump 51 controlled in water tank 50 is opened, to make water pump 51, the water of first area 501 in water tank 50 is entered in the guiding gutter 21 of indoor heat exchanger 20 by aqueduct 80, then indoor heat exchanger 20 is flowed into by the aperture of guiding gutter 21, fin along indoor heat exchanger 20 goes downstream, be pooled in the drip tray 60 bottom indoor heat exchanger 20, the aqueduct 90 finally connected by drip tray 60 is again back in the second area 502 of water tank 50.Owing to being provided with filter septum 52 between first area 501 and second area 502, therefore the water of second area 502 is after the filtration of filter septum 52, flows into first area 501 and circulates.
Further, as shown in Figure 5, the control method of above-mentioned humidifying air conditioner also can comprise:
Step S240, control water pump when detecting cleaning heat exchanger instruction and open after one first preset time, control water pump and close;
In the present embodiment, will the time of cleaning heat exchanger be limited, such as 10 minutes, when namely detecting cleaning heat exchanger instruction, control water pump 51 and open, and after 10 minutes, control water pump 51 and close.
After step S250, control room inner blower open one second preset time, stop the cleaning of heat exchanger, and the water of second area is discharged.
After control water pump 51 cuts out, control blower fan 30 and open, carry out drying process to realize the heat exchanger after to cleaning.In the present embodiment, also limit the preset opening time of blower fan 30, such as 5-10 minute.And when blower fan 30 opening time reaches preset time, control air-conditioner and shut down, or the operational mode of air-conditioner before the operational mode of air-conditioner being switched to cleaning heat exchanger.Meanwhile, after the cleaning exiting heat exchanger, also the water containing cleaning agent in second area 502 is discharged.Be understandable that, also a prompting function can be set, namely in second area 502, be provided with a level sensor.When detecting humidification instruction, if water sensor detects in second area 502 to also have water, then, after first being discharged by the water in second area 502, restart humidification.
Further, as shown in Figure 6, also comprised before the water pump of described control air-conditioner is opened in the control method of above-mentioned humidifying air conditioner:
The water level of step S150, acquisition water tank, with when the water level of described water tank reaches default threshold value, the water pump controlling air-conditioner is opened.
Level sensor is set in the first area 501 of water tank 50, to obtain the water level of water tank.When starting humidification function, when the water level detected by this level sensor reaches default threshold value, the water pump 51 controlling air-conditioner is opened, to start humidification function.
Corresponding said method embodiment, propose the control device of a kind of humidifying air conditioner of the present invention, as shown in Figure 7, the control device of this humidifying air conditioner comprises:
Detecting module 110, during for detecting humidification instruction, judges the humidification type that humidification instruction is corresponding;
Humidifying mode control module 120, for according to determined humidification type, controls described air-conditioner and is in corresponding pattern;
Water pump control modules 130, open for the water pump controlled in water tank, to make the water in water tank enter humidifying air conditioner by pipeline, and flow to bottom it by the top of the heat exchanger in humidifying air conditioner through heat exchanger, then be pooled in the drip tray of exchanger base, finally flow back into water tank again.
When user triggers humidification function by remote controller or humidifying air conditioner control panel, the electric-controlled box of humidifying air conditioner will detect humidification instruction.Now, will judge the humidification type that humidification instruction is corresponding, this humidification type can comprise normal humidification, powerful humidification etc.Certainly, also by increasing by a humidification decision circuitry in electric-controlled box 50, by obtaining the current humidity of room air, and current humidity and target humidity can be compared, to judge whether to start humidification function.To carry out humidification, then produce humidification instruction.Detecting module 110, when detecting humidification instruction, determines the humidification type that humidification instruction is corresponding.
Humidifying mode control module 120 specifically for:
When determined humidification type is normal humidification, controls described air-conditioner and remain on current operational mode.Such as, if when current operating modes of air conditioner is refrigeration mode, keeps the operational mode of current air-conditioner constant, start humidification function simultaneously, namely start water pump 51.
When determined humidification type is powerful humidification, controls described air-conditioner and switch to heating mode by current operational mode.Such as, if when current operating modes of air conditioner is refrigeration mode, controls air-conditioner and switch to heating mode by refrigeration mode, to promote the temperature on indoor heat exchanger surface.Start humidification function, namely start water pump 51, water extracts to heat exchanger top by water pump 51 from water tank, and flow to bottom it from heat exchanger top through heat exchanger simultaneously.The temperature on indoor heat exchanger surface raises, and will accelerate the evaporation of water on indoor heat exchanger surface, thus improves the humidity of the air through indoor heat exchanger surface, and then improve the humidity of room air.Due under powerful humidifying mode, air-conditioner be controlled and switch to heating mode, if the pattern before air-conditioner switching is just heating mode, then not need to switch.If the pattern before air-conditioner switches is refrigeration mode, and when now switching to heating mode for a long time, will affect the comfort level of user, therefore a period of time after switching to heating mode by refrigeration mode, heating mode is switched back refrigeration mode.Or after switching to heating mode by refrigeration mode, by real-time sensing chamber humidity, if indoor humidity reaches desired value, then switch back refrigeration mode.
When determined humidification type is automatic humidification, detects current humidity and environment temperature, and judge whether current humidity and environment temperature reach humidification entry condition, if reach normal humidification entry condition, then control air-conditioner and start normal humidification; If reach powerful humidified condition, then control air-conditioner and start powerful humidification.If do not reach humidification entry condition, then do not start humidification.This normal humidified condition and powerful humidified condition can be arranged according to specific circumstances.For powerful humidified condition: current humidity value is less than target humidity value, and the difference of described target humidity value and described current humidity value is greater than preset humidity threshold, and indoor temperature is less than preset temperature threshold value.Such as: current humidity value is less than target humidity value and differs by more than 20%RH with target humidity value, environment temperature, lower than 20 DEG C, can open powerful humidification function automatically.
Be understandable that, in order to save humidification power consumption, after startup humidifying mode, incite somebody to action sensing chamber's humidity in real time, if indoor humidity reaches target humidity, then stopping humidification.Or, when air-conditioner receives the humidification halt instruction that user sends, stop humidification.If carried out the switching of operational mode under humidifying mode, then the operational mode before switching back.
When starting humidifying mode, the water pump that water pump control modules 130 controls in water tank 50 is opened, thus make the water in water tank 50 enter humidifying air conditioner by pipeline, and by the top downstream of the heat exchanger 20 in humidifying air conditioner down to the bottom of heat exchanger 20, then be pooled in the drip tray 60 bottom heat exchanger 20, finally flow back into water tank 50 again.
If when air-conditioner is in current operation mode, blower fan 30 by air by the outside suction casing 10 of housing 10, and while indoor heat exchanger 20 after-blow enters indoor, air also by absorbing the steam on indoor heat exchanger 20 surface, therefore achieves the humidification function of air-conditioner.
If when air-conditioner is in heating mode, be blown into the steam that indoor air not only absorbs indoor heat exchanger 20 surface, and improve due to the temperature on indoor heat exchanger 20 surface, the current on indoor heat exchanger 20 surface can be made to accelerate evaporation in steam, thus make the humidity being blown into indoor air higher.
The embodiment of the present invention, when needs start humidification, first judges humidification type, then starts different air-conditioner humidifying mode according to humidification type, and open water pump.Therefore, the embodiment of the present invention according to humidification type, can control air-conditioner and not only achieves humidification function, but also meet different humidification requirements.
