Description
Technical field
The present invention relates to air-conditioning technical fields, more particularly to a kind of warm-air drier and its control method.
Background technique
In the prior art, if air-conditioning hot blast owner is under heating mode, the developing direction wanted based on high leaving air temp,
Its heat when leaving air temp compare conventional air-conditioning device heating when leaving air temp it is higher.In addition, when air-conditioning is in heating, heat
Air in humidity it is smaller, can it is very dry, when the face of the air blow-through of high temperature drying to people, can cause to have dry skin, make
At discomfort, user experience effect is run counter to desire.
For air conditioner heat blower indoor unit because of special use condition, mounting height generally will not be too high, so functionally, system
Under cold or dehumidification mode, top air port is opened only to meet indoor environment cooling or dehumidifying needs.But because air-heater is special
Configuration, refrigeration or the dehumidifying usual common air-conditioning leaving air temp of leaving air temp are lower, cause the chance of indoor machine evaporation frosting more
Greatly, after evaporating temperature is low to certain temperature, leads to frequent frequency reducing or shut down using as protection.Frequent frequency reducing stops
Machine, one side fluctuations in indoor temperature are big；On the other hand, frequent starting causes compressor reduced service life.On improving
Situation is stated, therefore proposes the invention patent, it is intended to propose a solution, when evaporating temperature reduces indoors, pass through this aspect
Scheme promotes evaporating temperature, reduces indoor environment temperature fluctuation, meanwhile, extend compressor service life as much as possible.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of warm-air drier and its control method, the controls
Method to solve the problems, such as hot wind blow-through under heating mode and cooling or the frequency reducing of dehumidification mode down coversion high frequent or
Person's halting problem.
In order to achieve the above object, the technical solution adopted by the present invention is that: a kind of warm-air drier, including indoor unit and outdoor
Machine, the indoor unit include indoor machine controller, top air outlet and lower air outlet, and several the are installed in the air outlet of top
Bottom wind wind guide strip on one or so pendulum wind wind guide strip and first, install in lower air outlet several second or so pendulum wind wind guide strips and
Bottom wind wind guide strip on second, first or so puts bottom wind wind guide strip on wind wind guide strip and first is walked by the first or so pendulum wind respectively
On into motor and first bottom wind stepper motor drive, second or so pendulum wind wind guide strip and second on bottom wind wind guide strip respectively by
Bottom wind stepper motor driving on second or so pendulum wind stepper motor and second, the first or so pendulum wind stepper motor, about first
Bottom wind stepper motor is controlled by indoor machine controller on pendulum wind stepper motor, second or so pendulum wind stepper motors and second,
Indoor machine controller is by remote control control.
A kind of control method of warm-air drier, the remote controler are equipped with anti-blow-through function button, anti-blow-through function button
Effect is to complete once-through operation within the set time.
When anti-blow-through function button on the remote controler starts, indoor machine controller, which receives to instruct, simultaneously controls indoor unit
Bottom wind stepper motor starts on the first of top air outlet, and bottom wind wind guide strip on the first of top air outlet is opened up
Default opening angle, while bottom wind stepper motor is opened preset downwards on the second of indoor machine controller control lower air outlet
Opening angle, at this time, if it is decided that there is no the air-conditioner winds of blow-through, this is without carrying out next-step operation, then it is assumed that anti-blow-through
Function realizes that, if lower air outlet is still to people's blow-through, then by the anti-blow-through function key on a remote controler, indoor unit controls
The second or so pendulum wind stepper motor that device receives instruction control lower air outlet closes second or so pendulum wind wind guide strips, while indoor
Machine controller controls bottom wind stepper motor on the second of lower air outlet and closes bottom wind wind guide strip on second；
When carrying out function switch using remote controler, then anti-blow-through function is automatically exited from, all pendulum wind wind guide strips are according to normal
Function control；
When completing third time anti-blow-through function button setting within the preset time using remote controler, then anti-blow-through is automatically exited from
Function, all pendulum wind wind guide strips are controlled according to normal function.
A kind of warm-air drier, blower and evaporating temperature sensor are provided in the indoor unit, and evaporating temperature sensor is real
When detection temperature and feed back to indoor machine controller, outdoor controller and frequency-changeable compressor are installed in the outdoor unit,
Outdoor controller receives evaporating temperature sensor signal and controls frequency-changeable compressor, and the relationship of indoor unit preset temperature is Tf0
> Tf1 > Tf2 > Tf3, Tf11 > Tf21 > Tf31.
A kind of control method of warm-air drier, the remote controler are equipped with refrigerating button or dehumidifying key, evaporating temperature
Sensor real-time detection temperature is T2, and when T2 temperature reaches preset temperature value Tf0, controller controls all steppings of indoor unit

First or so pendulum wind wind guide strip is opened default opening angle θ 2, in addition, controller control by the first or so pendulum wind stepper motor of mouth
Bottom wind wind guide strip on second is transferred to predetermined angle θ 3 by bottom wind stepper motor on the second of indoor unit lower air outlet processed；
Temperature signal is fed back to outdoor controller by indoor machine controller, and outdoor controller controls the frequency of frequency-changeable compressor no longer
Rise, can only keep or decline, until the frequency of frequency-changeable compressor is down to the minimum preset value H of requirement；When T2 temperature reaches
When to preset temperature value Tf11, frequency limit is exited.
After the frequency of frequency-changeable compressor is down to preset value H, when T2 temperature reaches preset temperature value Tf2, indoor unit control
Bottom wind stepper motor in device control second controls bottom wind wind guide strip on second and opens predetermined angle θ 4；When T2 temperature reaches
When preset temperature value Tf21, bottom wind stepper motor closes bottom wind wind guide strip on second in indoor machine controller control second；
When T2 temperature reaches preset temperature value Tf11, frequency limit is exited.
When T2 temperature reaches preset temperature value Tf3, the blower of machine promotes 1 grade until most in indoor machine controller control room
Big revolving speed S, maximum (top) speed S are higher than indoor unit highest setting revolving speed；When T2 temperature reaches preset temperature value Tf31, indoor unit
Blower is restored to revolving speed gear before protection；When T2 temperature reaches preset temperature value Tf21, indoor machine controller control second
Upper bottom wind stepper motor closes bottom wind wind guide strip on second；When T2 temperature reaches preset temperature value Tf11, frequency is exited
Limitation.
