Be referred to multiple preferred embodiment of the present invention in detail, the Multi-instance of these preferred embodiments shows in the accompanying drawings, those figures show:
The schematic diagram of Fig. 1 clothes washing treatment facility, and
Fig. 2 shows the flow chart of the embodiment realizing cooling fan Elementary Function.
Fig. 1 shows the clothes washing treatment facility 2 of schematic representation, and this clothes washing treatment facility is heat pump cylindrical drier in this embodiment.Cylindrical drier 2 comprises heat pump 4, this heat pump comprises closed refrigerant loop 6, this loop comprises the flow of refrigerant B: the first heat exchanger 10 of following order, and this first heat exchanger serves as evaporimeter to evaporate this cold-producing medium and cooling disposal air; Compressor 14; Second heat exchanger 12, this second heat exchanger serves as condenser with cooling refrigeration agent with add thermal treatment air; And expansion gear 16, cold-producing medium is back to the first heat exchanger 10 from this expansion gear.Together with the refrigerant tubing these unit Series of this heat pump 4 connected, this heat pump defines refrigerant loop 6, and cold-producing medium is circulated through this refrigerant loop by compressor 14, as shown by arrow B.
Disposal air stream in treatment facility 2 is guided through the compartment 18 of home appliances 2, namely through the compartment for receiving pending article, and such as cylinder 18.Pending article are had to be fabric, clothing 19, clothes, shoes etc.Dispose air stream indicated by arrow A in FIG and driven by disposal air-blaster 8.Dispose air duct 20 dispose air stream A outer guiding of cylinder 18 and comprise multiple different section, these sections comprise the section that formation row organizes passage 20a, have arranged the first and second heat exchangers 10,12 in this section.After disposal air out flows into one from the second heat exchanger 12 in passage 20b, dispose air-blaster 8 and be arranged in this rear passage.The air that air blast 8 transmits is directed upwards the dorsal part to cylinder 18 in a rising passway 20c.The air leaving cylinder 18 through drum outlet (being the loading opening of this cylinder) is by being arranged among passage 20 or part is filtered near the lint filter 22 of drum outlet.This optional lint filter 22 is arranged in the prepass 20d of another section forming passage 20, and this prepass is arranged at the protecgulum rear of drying machine 2 and adjacent with it.The condensate formed at the first heat exchanger 10 place is collected and guides to condensate collector 30.
Condensate collector 30 is connected to via drainage pipeline 46, draining pump 36 and drawer pipeline 50 in the condensate drawer 40 that can extract out.That is, collected condensate can be pumped to drawer 40 from collector 30, and this drawer is arranged at the upper part place of equipment 2, and user can be taken out like a cork by this drawer here and emptying.
Cooling fan unit 53 comprises air blast 54 and the motor 56 for activating air blast 54.Cooling fan unit 53 is arranged to for cool compressor 14 and for the part to its power unit 52 and/or this power unit 52, cool as the electronic inverter of a part for power unit 52 particularly.Usually, automatically occurred by cooling stream 58 cooling of power unit 52 (particularly to its inverter), this cooling stream is generated for cooling compressor 14 according to specific cooling request under some operator schemes.But, in some operating modes, do not need to cool compressor 14 and therefore also not to power unit 52 and particularly its inverter cool.But, even if do not cool compressor 14, may desirably be cooled power unit 52/ inverter.This to the cooling desired by power unit 52/ inverter in order to implement under the control of control unit 51, the mode that cooling fan unit 53 is activated is at least minimum delivery ability ensureing cooling fan unit 53.
Preferably, control unit 51 is the control unit for controlling the integrated operation of equipment 2 and monitor simultaneously.Such as and as shown in fig. 1, control unit 51 receives temperature signal from temperature sensor 41, this temperature sensor is arranged at the exit of the second heat exchanger 12 (condenser) and indicates the refrigerant temperature of that position.
In normal operating, control unit 51 operates or activates cooling fan unit 51 in response to the temperature signal received from temperature sensor 41.When cooling fan unit 51 is activated, this means that cooling-air C is blowed to compressor 52 by air blast 54 and therefore also at the rack Inner eycle of equipment 2, the state of fan unit 53 is configured to STAT_FAN=" forces running (Force ON) ".By control unit 51 implement and the control program as described below interim activation fan unit 53 when multiple (prolongation), interim at these time, due to carry out sensor 41 temperature indication shown in cooling needs, fan unit 53 is not activated or is enough fully activated separately.The additional cooling of as described below this can be named as ' preferentially cooling ' (by sensor 41 signal) that the cooling that has precedence over compressor requires.On the other hand, if the signal designation from temperature sensor 41 goes out to need cooling compressor (this depends on other parameters instead of only temperature signal in addition), by following program, activation according to requiring the cooling of the miscellaneous part (such as, power unit 52) in equipment enclosure is preferably had precedence over to the activation of fan unit 53.Therefore, no matter compressor or miscellaneous part are cooled the need of being activated by air blast, all ensure that minimum cooling.
The running of cooling fan unit 53 is explained by the flow chart according to Fig. 2.Under base control pattern, whether continuous review cooling fan unit 53 is activated, and (such as, controlling to activate by temperature) (step S1) carries cooling stream 58.This result (monitoring) checked is stored by control unit 51, that is, storage cooling fan unit 53 " running " how long Δ t.This corresponds to the step S1.1 in this flow chart, that is, the cooling fan T_on duration of runs adds the monitored units of delta t duration of runs.In following steps S2, compare cooling fan and be worth T_on the duration of runs and whether be greater than predefined guarantee time (or minimum running time can be expressed as) value T_en.If meet this condition, then by making timeline reset t=0 (step S3) restart monitoring during predefined monitoring time section T_p.This means how long it monitors and store cooling fan unit 53 " running " again.This monitoring is at most occur in the predefined time frame from t=0 to t=T_p.For this purpose, the cooling fan T_on duration of runs is also reset T_on=0 in step S3.
If the value of time value T_on equals predefined guarantee time value T_en or be even less than to ensure time value T_en in step s 2, then confirm whether monitoring phase time T_p passes by (step S4).In other words, if time value T_on is not higher than defined guarantee time value T_en at the end of detector time T_p, then the state (STAT_FAN) of cooling fan unit 53 is configured to " operating by force " (step S5), thus therefore enables the priority acccess control of cooling fan unit 53.The time span that state STAT_FAN is configured to " operating by force " defines by being worth T_f_on the duration of runs by force.This value T_f_on equals to ensure that the cooling fan of time value T_en and detection to be worth the difference between T_on (step S4.1) duration of runs.In order to avoid cooling fan unit 53 keeps " operating by force " state with continuing irrelevant time span, there are two and examine step S4.2 and S4.3.
In step S4.2, examine and be worth T_f_on the calculated duration of runs by force and whether wane time value T_tol lower than predefined tolerance.If be worth T_f_on by force the duration of runs to wane the time lower than predefined tolerance, then cooling fan unit 53 can not be activated with " operating by force " state.Therefore, avoid cooling fan unit 53 repeatedly and inefficient in short-term start and shut-down operation.
Predefined tolerance in step S4.2 wanes time value T_tol lower than the predefined minimum guarantee time value T_min_en in step S4.3.In step S4.3, examine calculated value T_f_on be whether higher than or at least equal predefined minimum guarantee time value T_min_en.If meet this condition, then cooling fan unit 53 will be " by force operate " or be activated with " operating by force " state and continue to equal the time span being worth T_f_on the duration of runs by force of original calculation.If the time value T_f_on of original calculation is less than predefined minimum guarantee time value T_min_en, then cooling fan unit 53 will be " by force operate " or be activated with " operating by force " state and continue to equal minimum guarantee time value T_min_en (step S4.4).
If detect that the state of cooling fan unit 53 is that STAT_FAN=" operates " (step S6) by force, then this priority acccess control makes cooling fan unit 53 be activated or " startup " (step S7).After this activates, examine and be worth T_f_on the determined duration of runs by force and whether pass (step S8).If no, then state STAT_FAN remains on " operating by force " (step S9).Be worth T_f_on, then disabled status STAT_FAN the determined duration of runs by force if passed, that is, state STAT_FAN is configured to forbid (" operating by force ") (step 10).This disabled status to make during predefined monitoring phase time T_p and according to restarting monitoring (step S11) under the base control of step S1.This is the program identical with step S3, that is, by making timeline reset t=0 restart the monitoring phase.This means how long it monitors and store cooling fan unit 53 " running " again.This monitoring is at most occur in the predefined time frame from t=0 to t=T_p.For this purpose, the cooling fan T_on duration of runs is also reset T_on=0 in step S11.
