And the components such as filter screen are effectively cleaned.
After superheated vapor is cooling, it can be in contact with the interior machine coil pipe after cooling, form condensation inside and outside evaporator, most
End form flows into drip tray at stock water flow.Comprehensive cleaning is carried out using the internal machine heat exchanger of water flow.And it is solidifying with frosting early period
Dew cleaning forms " double washings " self-cleaning function.
Example IV,
It is illustrated in figure 6 control when defrost stage inner blower positive and negative rotation switch mode in another embodiment provided by the invention
Flow chart processed.Shown in specific as follows:
When frost layer reaches certain thickness, into the defrost stage, inner blower stopping movement or slow-speed of revolution operating.Air conditioner with
Heating mode operation, TpEqual to Tf1When, and runing time meets tf1, inner blower enters the soft outlet air mould of positive and negative rotation switching at this time
Formula.
Inner blower reversion, as shown in figure 4, inner blower is with revolving speed n2Run t2After time, Rule of judgment two: interior machine coil pipe temperature
Degree is lower than third preset temperature Tp≤Tn+f2(Tn, Tw) whether meet, if meeting condition two, inner blower exits positive and negative rotation and switches out
Wind mode, and restore to operate normally, until exiting self-cleaning function.
If being unsatisfactory for condition two, judge whether to meet condition three, four；If meeting condition three: interior machine coil temperature meets
5th preset temperature range f2(Tn, Tw)≤Tp≤Tn+f1(Tn, Tw), inner blower rotates forward, with n3Run t3Afterwards, inner blower inverts,
With n4Run t4Afterwards, then rejudge whether meet condition two；If meeting condition four: interior machine coil temperature meets the 4th default temperature
Spend range f3(Tn, Tw)≤Tp≤Tn+f2(Tn, Tw), then inner blower stopping acts, and meets the first dwell time tstop1Afterwards, interior wind
Machine reversion, with n4Run t4Afterwards, then rejudge whether meet condition two.
Switching control is looped back and forth like this, until meeting condition two, inner blower exits positive and negative rotation switch mode, and restores just
Transhipment row, exits self-cleaning function.
Guarantee human body comfort and realize that high-temperature steam cleans heat exchanger effect, when shortening self-cleaning function mode operation
Between.
The superheated vapor for being stranded in indoor unit body not only cleans entire heat exchanger, also to entire indoor unit body
Comprehensive cleaning is carried out, it is especially stronger to components bacteriostasis such as the chassis such as heat exchanger, the blower of close inner blower side；By entering the wind
Superheated vapor heat exchanging device top (close to air inlet) cleaning action of mouth discharge is stronger, can be to the heat exchanger component of air inlet side
And the components such as filter screen are effectively cleaned.
After superheated vapor is cooling, it can be in contact with the interior machine coil pipe after cooling, form condensation inside and outside evaporator, most
End form flows into drip tray at stock water flow.Comprehensive cleaning is carried out using the internal machine heat exchanger of water flow.And it is solidifying with frosting early period
Dew cleans formation " double washings " self-cleaning function (similar with traditional condensation mode early period in frosting stage).
It is using reversed flow field or turbulence flow flied that the generation of defrost stage indoor unit is more by way of inner blower positive and negative rotation
Steam be stranded in indoor unit body certain time, and part superheated vapor is discharged by air inlet, then rotated forward by inner blower,
The steam part discharge that temperature is reduced reduces influence of whole superheated vapors discharges to human body comfort.
Embodiment five,
It is illustrated in figure 7 defrost stage high-temperature steam complete machine cleaning model inner blower in another embodiment provided by the invention
Control flow chart.Shown in specific as follows:
Into the defrost stage, inner blower stopping is acted or is operated with the slow-speed of revolution.Air conditioner is run with heating mode, and high temperature is cold
Matchmaker flows into interior machine coil pipe, and interior machine coil temperature rises, and works as TpRise to Tf2When, and runing time meets tf2, inner blower entrance
Operation mode is inverted, inner blower is with n5Run t5Reversion, while auxiliary heat function is opened, by adjusting auxiliary heat input power P, into one
Step improves the temperature of superheated vapor, forms high-temperature steam, and in tgIt is interior, keep the 6th preset temperature range Tpg1≥Tp≥Tpg2,
Auxiliary heat function is closed later, exits " high-temperature steam " complete machine cleaning model.Inner blower starts to invert, with n6Run t6Afterwards, into just
Reversion switches soft air-out mode, until exiting self-cleaning function.
Heat exchanger and complete machine are cleaned using high-temperature steam, obtains preferable antibiotic and sterilizing effect, guarantees human body comfort, contracting
The short self-cleaning function mode operation time.
By inputting auxiliary heat, high-temperature steam is converted by the superheated vapor for being stranded in indoor unit body, utilizes higher temperature
Steam comprehensive cleaning is carried out to entire indoor unit body, so that interior machine coil pipe is kept high temperature for a period of time, it is preferable to obtain
Antibiotic and sterilizing effect, it is stronger to components bacteriostasis such as the chassis such as heat exchanger, the blower of close inner blower side；It is discharged by air inlet
High-temperature steam heat exchanging device top (close to air inlet) and the member sterilizations bacteriostasis such as filter screen it is stronger.
After superheated vapor is cooling, it can be in contact with the interior machine coil pipe after cooling, form condensation inside and outside evaporator, most
End form flows into drip tray at stock water flow.Comprehensive cleaning is carried out using the internal machine heat exchanger of water flow.And it is solidifying with frosting early period
Dew cleans formation " double washings " self-cleaning function (similar with traditional condensation mode early period in frosting stage).
It is using reversed flow field or turbulence flow flied that the generation of defrost stage indoor unit is more by way of inner blower positive and negative rotation
Steam/steam be stranded in indoor unit body certain time, and part superheated vapor/steam is discharged by air inlet, then passes through
Inner blower rotates forward, and the steam part that temperature is reduced is discharged, and the influence to human body comfort is discharged in the whole superheated vapors of reduction.
