Degree, to further strengthen the protection to heat pump system 3.
Also, compared to only controlling auxiliary heating system by the detection single temperature such as delivery temperature or suction temperature
In the case where 4 mode, it is possible to which will appear detection temperature (such as delivery temperature) is normal, but heat pump system others temperature
The case where (such as suction temperature) has been over limiting value, continues to run auxiliary heating system 4 at this time and will cause heat pump system and 3 surpass
Overload is to cause heat pump system 3 to damage.Therefore by the way of monitoring delivery temperature and suction temperature simultaneously, in order to more
Add the working condition for accurately knowing heat pump system 3 to control auxiliary heating system 4.
It is understood that the judgement of delivery temperature and suction temperature is carried out simultaneously in above-mentioned deterministic process,
It is of course also possible to successively be judged with suction temperature delivery temperature, such as it can first judge whether delivery temperature is less than exhaust
Then ceiling temperature selectively judges whether suction temperature is less than return-air ceiling temperature again according to comparison result.Specifically,
When delivery temperature is more than or equal to exhaust ceiling temperature, you can get it, and heat pump system 3 has reached maximum load, later just without sentencing
Disconnected suction temperature；When delivery temperature is less than exhaust ceiling temperature, it is further continued for judging whether suction temperature is less than on suction temperature

Degree is less than return-air ceiling temperature；2) delivery temperature is less than exhaust ceiling temperature, and suction temperature is more than or equal to return-air ceiling temperature；3)
Delivery temperature is more than or equal to exhaust ceiling temperature, and suction temperature is more than or equal to return-air ceiling temperature.No matter which kind of above-mentioned situation, only
When delivery temperature being wanted to be more than or equal to its corresponding ceiling temperature at least one in suction temperature, this means that heat pump system 3 reaches
To maximum load, then need to close auxiliary heating system 4 to reduce the load of heat pump system 3 at this time.
After closing auxiliary heating system 4, the suction temperature and delivery temperature of heat pump system 3 will be reduced, but work as
When suction temperature and delivery temperature are lower than corresponding lower limit temperature, heat pump system 3 will be can not work normally, it is therefore preferred that
The present invention also controls the reopening in order to by heat pump system 3 of auxiliary heating system 4 by delivery temperature and suction temperature
Operating temperature maintain setting range, to guarantee the normal operation of heat pump system 3.
Specifically, drying control method of the invention further include:
S24: it is the target pattern that heat pump system 3 and auxiliary heating system 4 are opened in selected original state, and executes
S23 closes auxiliary heating system 4, in the case where only running heat pump system 3, judges whether delivery temperature is less than the default temperature of third
Whether degree and suction temperature according to result selectively reopen auxiliary heating system 4 less than the 4th preset temperature.
Third preset temperature is exhaust lower limit temperature, and the 4th preset temperature is return-air lower limit temperature, by by delivery temperature
It is compared respectively with exhaust lower limit temperature with return-air lower limit temperature with suction temperature, to accurately obtain heat pump system 3
Working condition.Of course, it is possible to by the numerical value of third preset temperature and the 4th preset temperature be set above exhaust lower limit temperature and
Return-air lower limit temperature, to further strengthen the protection to heat pump system 3.
It is understood that the judgement of delivery temperature and suction temperature is carried out simultaneously in above-mentioned deterministic process,
It is of course also possible to successively be judged with suction temperature delivery temperature, such as it can first judge whether suction temperature is less than exhaust
Then lowest temperature temperature selectively judges whether delivery temperature is less than return-air lower limit temperature again according to comparison result.Tool
Body, when delivery temperature is less than delivery temperature lower limit temperature, later just without judging suction temperature；Be greater than when delivery temperature or
When equal to delivery temperature ceiling temperature, it is further continued for judging whether suction temperature is less than suction temperature ceiling temperature.Art technology
Personnel can adjust the logical order for executing above-mentioned temperature judgement, reasonably in order to adapt to have according to actual needs

Delivery temperature be less than exhaust ceiling temperature and suction temperature be less than return-air ceiling temperature, this means that heat pump system this
When operating temperature be still not below lower limit value, heat pump system is still within normal operating conditions, keeps auxiliary heating system at this time
Closed state.
S242: when delivery temperature is less than third preset temperature or suction temperature less than four preset temperatures, step is executed
Rapid S20 reopens auxiliary heating system 4, run heat pump system 3 simultaneously with auxiliary heating system 4.
Above-mentioned steps S242 is broadly divided into three kinds of situations, i.e., 1) delivery temperature is less than third preset temperature, and suction temperature is big
In equal to the 4th preset temperature；2) delivery temperature is more than or equal to third preset temperature, and suction temperature is less than or equal to the 4th default temperature
Degree；3) delivery temperature is less than third preset temperature, and suction temperature is less than the 4th preset temperature.No matter which kind of above-mentioned situation, as long as
When delivery temperature is less than its corresponding ceiling temperature at least one in suction temperature, this means that heat pump system 3 is lower than work
Temperature, at this time in order to improve the operating temperature of heat pump system 3 to guarantee the stable operation of heat pump system 3, it is therefore desirable to open again
Open auxiliary heating system 4.Also, reopening for auxiliary heating system 4 also contributes to again heating the gas in air duct 2,
So that being increased again into the gas temperature in roller 1, to accelerate the Drying Rates of clothing, to guarantee the quick baking of clothing
It is dry.
