CPU detects the surface temperature Te of evaporimeter 23 according to the temperature signal from evaporator temperature sensor 36 when proceeding to step S44, the testing result of surface temperature Te and the last a reference value (for example 0 ℃) that is stored among the ROM are in advance compared.At this, when being judged as " Te 〉=last a reference value ", carry out to step S45, the rotary speed of compressor motor 25 is measured accordingly from present speed raising and the unit value that is stored in the ROM in advance.Then, carry out, the aperture of electric expansion valve 28 is measured with the unit value that is stored in the ROM in advance accordingly from current aperture minimizing to step S46.That is, when the surface temperature Te of evaporimeter 23 dropped to smaller or equal to following a reference value, the flow that makes refrigerant reduced and the aperture of electric expansion valve 28 is increased from currency from currency, thereby the surface temperature Te of evaporimeter 23 rises.In addition, the surface temperature Te of evaporimeter 23 rise to more than or equal on during a reference value, the flow that makes refrigerant increases and the aperture of electric expansion valve 28 is reduced from currency, thus the surface temperature Te of evaporimeter 23 descends.In a word, CPU controls the flow regime of the refrigerant of heat pump 43, and feasible temperature signal from evaporator temperature sensor 36 is converged in the predetermined certain limit.

CPU according to the temperature signal from hot blast temperature sensor 40, detects the hot blast temperature Tf that is discharged in the cylinder 5 when proceeding to the step S14 of Fig. 5, and the testing result of hot blast temperature Tf and a reference value that is stored among the ROM are in advance compared.At this, when being judged as " Tf 〉=a reference value ", carry out to step S16, by-passing valve 30 is switched to open mode from closed condition.

CPU is judged as " hot blast temperature Tf＜a reference value " in step S14 after, in step S15, judged whether to pass through the valve switching time that is stored in advance among the ROM according to the instrumentation value of counter.The water filling that this valve is set to step S18 switching time again ETAD expected time of arrival and departure 1/2, for example 10 minutes.CPU has begun compressor motor 25 in step S11 constant speed drive is a benchmark, judges to have passed through valve during switching time, carries out to step S16 from step S15, and by-passing valve 30 is switched to open mode from closed condition.

CPU has opened by-passing valve 30 in step S16 after, carry out the evaporator temperature control of step S17 and handle.The control of the evaporator temperature of this step S17 is handled identical with the content of step S13, and the flow by controlling refrigerant respectively and the aperture of electric expansion valve 28 are converged in the surface temperature Te of evaporimeter 23 in the setting range.CPU is when step S17 proceeds to step S18, judged whether to pass through the water filling that is stored in advance among ROM ETAD expected time of arrival and departure (for example 20 minutes) again according to the instrumentation value of counter.

CPU has begun compressor motor 25 in step S11 constant speed drive is a benchmark, judges and to have passed through water filling again during ETAD expected time of arrival and departure, carries out to step S19 from step S18.At this, by feed water valve 7 is switched to hot water water filling state from the water filling halted state, begin running water is injected in the Storage water tank 3 through water injecting tank 9 from water pipe 10, the evaporator temperature control that proceeds to step S20 is then handled.The evaporator temperature control of this step S20 is handled identical with the content of step S13, controls the aperture of the flow and the electric expansion valve 8 of refrigerant respectively, thereby the surface temperature Te of evaporimeter 23 is converged in the setting range.CPU detects the water level in the Storage water tank 3 after proceeding to step S21 from step S20, and the testing result of water level is compared with the setting result of the water level of step S3.

CPU carries out to step S22 after judging that in step S21 the water level in the Storage water tank 3 has arrived the setting result of water level.At this, by feed water valve 7 is switched to the water filling halted state from hot water water filling state, stop in Storage water tank 3, to inject the action of running water, the evaporator temperature control that proceeds to step S23 is then handled.The evaporator temperature control of this step S23 is handled identical with the content of step S13, controls the aperture of the flow and the electric expansion valve 28 of refrigerant respectively, thereby the surface temperature Te of evaporimeter 23 is converged in the setting range.CPU has judged whether to pass through the circulation dwell time (cycle outage time) that is stored in advance among the ROM according to the instrumentation value of counter after proceeding to step S24 from step S23.

CPU stops the water filling action in step S22 be benchmark, judges when having passed through the circulation dwell time, proceeds to step S25 from step S24.At this, compressor motor 25 runnings are stopped, fan motor 21 runnings are stopped, in step S27, electric expansion valve 28 is adjusted to the aperture (aperture that for example is equivalent to 400 pulses) that is stored in advance among the ROM, then carry out to step S28.

CPU has judged whether to pass through the hot water scavenging period that is stored in advance among the ROM according to the instrumentation value of counter when proceeding to step S28.The process of this hot water scavenging period be with in step S5 the beginning drum motor 4 intermittent running be that benchmark is judged.CPU be judged as passed through the hot water scavenging period after, carry out to step S29 from step S28.At this, drum motor 4 runnings are stopped, finishing the hot water clean.

Fig. 7 is the figure of the flow process of the hot water clean of step S1～step S29 in the presentation graphs 5.In this hot water clean, synchronously begin the intermittent running of cylinder 5 with the beginning of cold water water flood treatment, the washings in cylinder 5 injects the running water of normal temperature.In the implementation of this cold water water flood treatment, stop fan motor 21 and compressor motor 25 respectively, split condenser 22, evaporimeter 23 and split condenser 26 become normal temperature respectively.

After having stopped the cold water water flood treatment, under the closed condition of by-passing valve 30, make fan motor 21 and compressor motor 25 entrys into service respectively, in Storage water tank 3, inject hot blast, the water temperature in the Storage water tank 3 rises thus.From this hot blast inject handle begin to passed through till the stand-by time during in, fan motor 21, compressor motor 25 and electric expansion valve 28 turn round under predefined rigid condition respectively.Split condenser 22 and split condenser 26 temperature separately sharply rise in this open loop control period, and the temperature of evaporimeter 23 sharply descends.

After having passed through stand-by time,, respectively the operating condition of compressor motor 25 and the operating condition of electric expansion valve 28 are controlled according to the surface temperature Te of evaporimeter 23 from beginning hot blast injection processing.This FEEDBACK CONTROL (feedback control) is performed until fan motor 21 and compressor motor 25 shuts down respectively, be till cycle operation (cycle operation) finishes.The surface temperature Te of evaporimeter 23 is controlled in the target zone in during FEEDBACK CONTROL, in during till from the beginning FEEDBACK CONTROL to beginning hot water water flood treatment, split condenser 22 and split condenser 26 temperature separately rise lentamente than the open loop control period.

The beginning hot blast inject handle that this finishes dealing with during in, the hot and humid air in the cylinder 5 is by evaporimeter 23 condensations or condense, the temperature of air is kept under the effect of this latent heat heat exchange necessarily.Therefore, the device 23 temperature reduction singularly that can avoid evaporating is so suppressed split condenser 22 and split condenser 26 temperature reduction separately.Inject the implementation of handling at this hot blast, after hot blast temperature Tf arrives a reference value, open by-passing valve 30.Switching timing to this by-passing valve 30 is set the limit time.This limit time is set to such an extent that regularly want Zao than the beginning of hot water injection processing, does not arrive a reference value and has passed through limit during the time at hot blast temperature Tf, opens by-passing valve 30 before hot water injection processing begins.

Inject processing at hot water, through water pipes 10 running water is injected in the Storage water tank 3 from feed water valve 7.The surface temperature of split condenser 26 rises significantly before being about to begin this hot water water flood treatment, the running water after hot water treatment and then begins in the water pipe 10 since absorbed split condenser 26 self thermal capacity and sharp significantly the temperature of intensification and split condenser 26 sharply descend.Therefore, make the refrigerant of discharging from compressor 24 get around split condenser 22 concentrated areas and flow to the split condenser 26, so that the temperature maintenance of split condenser 26 in the decline level.Under this state, the running water in the water pipe 10 absorbs thermal capacity from the refrigerant in the refrigerant pipe 27 of split condenser 26, the hot water of the corresponding temperature of temperature of the refrigerant of injection and split condenser 26 in Storage water tank 3.The internal diameter size of this water pipe 10 is set to the water pipe of using less than the cold water water filling 8, lacks than the cold water water flood treatment thereby the hot water water flood treatment is set to the water injection rate of its unit interval.

CPU has finished the hot water clean in the step S29 of Fig. 5 after, the rinsing of the draining processing of execution in step S30 and step S32 is handled in turn.It is that the hot water that will remain in the Storage water tank 3 in the hot water clean is discharged to machine exterior that the draining of step S30 is handled.CPU carries out the draining processing by opening draining valve 13.The rinsing of step S32 is handled, and retains the corresponding running water of measuring with the setting result of water level once more in Storage water tank 3, and the washings in the cylinder 5 are fallen in the water that does not contain detergent ingredients, removes detergent ingredients from washings thus.CPU is in the rinsing of step S32 is handled, draining valve 13 is switched to closed condition from open mode, feed water valve 7 is switched to cold water water filling state from the water filling halted state, thereby pass through water injecting tanks 9 inject normal temperature in Storage water tank 3 running water from water pipe 8, and washings is dropped in the water by rotary manipulation drum motor 4.

CPU after the clean of having finished step S32, the processed of the draining processing of execution in step S33 and step S34 in turn.It is that the running water that will remain in rinsing is handled in the Storage water tank 3 is discharged to machine exterior that the draining of step S33 is handled.CPU carries out the draining processing by opening draining valve 13.The processed of step S34 is to discharge moisture by centrifugal force from the washings in the cylinder 5.CPU carries out processed by making drum motor 4 runnings.

CPU after the processed of having finished step S34, the cooling processing of the dried of execution in step S35 and step S36 in turn.The dried of step S35 is to make drum motor 4, fan motor 21 and compressor motor 25 runnings respectively, while make the washings of cylinder 5 rotations in cylinder 5 blow the dry wind of high temperature low humidity.In this dried, by-passing valve 30 is switched to closed condition, the refrigerant of discharging from compressor 24 circulation in split condenser 22 and split condenser 26 respectively.The cooling processing of step S36 is to make drum motor 4 and fan motor 21 runnings respectively, while make the washings of cylinder 5 rotations in cylinder 5 blow the temperature cooling air lower than dry wind.This cooling air is the normal temperature wind that does not carry out heat exchange by thermal cycle 43, and the washings that has heated up in the dried of step S35 is cooled off.

According to the foregoing description 1, can play following effect.

By feed water valve 7 being made as cold water water filling state, carry out the cold water water flood treatment, promptly, the running water of normal temperature is injected in the Storage water tank 3 without water pipe 10 ground, stop the back by difference fans in operation device 41 and compressor 24 in the cold water water flood treatment, carry out the hot blast injection and handle, promptly in Storage water tank 3, inject hot blast.Inject at this hot blast and to handle, the air that has absorbed the high humility of the moisture in the Storage water tank 3 turns back to evaporimeter 23 from Storage water tank 3, carries out the latent heat heat exchange with evaporimeter 23, thus condensate moisture or condense.Therefore, even outer temperature degree is the low temperature about 5 ℃, compressor 23 also is difficult to frosting, thereby can suppress to hinder wind flowing with respect to evaporimeter 23 and split condenser 22 respectively because of frost.So the running efficiency that has suppressed heat pump 43 reduces, thereby make split condenser 22 and split condenser 26 all heat up easily.

Begin to having passed through water filling moment of ETAD expected time of arrival and departure again inject handling from hot blast, the temperature of split condenser 26 is injected to handle than hot blast and is become enough high when beginning, when the temperature of split condenser 26 becomes enough high, feed water valve 7 is switched to hot water water filling state, begin hot water thus and inject processing, that is, running water is injected in the Storage water tank 3 by water pipe 10.After and then this hot water injects the processing beginning, thereby running water in the water pipe 10 heats up significantly by the thermal capacity that has absorbed split condenser 26 self, is injected in the Storage water tank 3 so absorbed the hot water that becomes high temperature after the thermal capacity of split condenser 26 self.Therefore, water temperature can be warmed up to the temperature that is suitable for washing, thereby the ability of cleaning improves.

The flow regime of the refrigerant of control heat pump 43 makes the testing result of evaporator temperature sensor 36 be converged in the predetermined certain limit.Therefore, make split condenser 22 and split condenser 26 temperature separately rise rapidly, thereby shortened the required time of running water heating that makes in the Storage water tank 3.And the temperature of refrigerant that turns back to the inside of compressor 24 from evaporimeter 23 uprises, so the temperature of the lubricating oil in the compressor 24 also uprises.Therefore, the dissolve in amount of refrigerant can be suppressed, thereby the greasy property reduction of the lubricating oil that causes can be suppressed to change because of the oil dilution degree with respect to lubricating oil.Therefore, can prevent to move swimmingly, thereby improve reliability at the internal part of compressor 24.

At the outlet of compressor 24, as shown in Figure 8, be connected with triple valve 45.This triple valve 45 is driven by the valve solenoid that comprises o (valve solenoid).This triple valve 45 can make the refrigerant of discharging from compressor 24 flow into the water filling state split condenser 26 and the split condenser 22 respectively and make the refrigerant of discharging from compressor 24 not flow into split condenser 26 and flow between the drying regime of split condenser 22 and switch.

Fig. 9 is illustrated in the control content of control circuit 34 when being set at the hot water wash course.The CPU of control circuit 34 has retained water filling when interrupting the running water of normal temperature of water level in Storage water tank 3, in step S7 feed water valve 7 is switched to the water filling halted state from cold water water filling state.Then, in step S8 triple valve 45 is switched to the water filling state, the aperture to electric expansion valve 28 in step S9 is carried out initial setting, the constant speed drive of beginning fan motor 21 in step S10, the constant speed drive of beginning compressor motor 25 in step S11.Then, execution in step S12～step S34 switches to drying regime with triple valve 45 from the water filling state in the dried of step S35 under the water filling state of triple valve 45.Therefore, refrigerant flows through split condenser 22 and split condenser 26 respectively in the hot water clean of step S12～step S27, refrigerant does not flow through split condenser 26 and flows through split condenser 22 in the dried of step S35, thereby has improved the formation efficiency of the hot blast that is used for dry washing material in the dried of step S35.

In the foregoing description 2, also can constitute, in the dried of step S35 when the temperature anomaly of split condenser 22 rises, triple valve 45 is switched to the water filling state from drying regime, feed water valve 7 is switched to hot water water filling state from the water filling halted state, it is cooled off by making refrigerant in split condenser 26, carry out heat exchange.

In the foregoing description 1～embodiment 2, the condenser that all can use shell-and-tube is as split condenser 26.

In the inside of trunk line 16, as shown in figure 10, take in the condenser 50 of corrugated fin formula.This condenser 50 constitutes, and gets involved being provided with a plurality of fin each other at the line part of a refrigerant pipe that is the shape that crawls, and a plurality of fin are engaged with the line part of refrigerant pipe respectively.Figure 11 (a) shows the pipe arrangement state of condenser 50.The refrigerant pipe 51 of condenser 50 is aligned to four row on left and right directions.On a plurality of fin of this condenser 50, engage a water pipe 52 that is the shape that crawls is arranged.This water pipe 52 is aligned to two row on left and right directions.The inner face of water pipe 52 shown in Figure 11 (b), is made of even surface.Each row of this water pipe 52 shown in Figure 11 (a), between the row of refrigerant pipe 51, contact with refrigerant pipe 51 across the fin of condenser 50 indirectly.This water pipe 52, as shown in figure 10, the heating that is connected feed water valve 7 via water pipe 10 is with on the delivery outlet, and under the hot water water filling state of feed water valve 7, running water is injected in the tank 3 from the water pipe 52 and the water injecting tank 9 of water pipe 10 through condenser 50.

The control content of the control circuit 34 when Figure 12 represents to be made as the hot water wash course.When the CPU of control circuit 34 leaves the normal temperature running water of water filling interruption water level at Storage water tank 3 internal memories, in step S7, feed water valve 7 is switched to the water filling halted state from cold water water filling state.Then, the aperture to electric expansion valve 28 in step S9 is carried out initial setting, the constant speed drive of beginning fan motor 21 in step S10, the constant speed drive of beginning compressor motor 25 in step S11.Be judged as when the constant speed drive of this compressor motor 25 begins to have passed through stand-by time, proceed to step S17 and step S18 respectively from step S12, surface temperature Te with evaporimeter 23 is controlled in the setting range of " 5 ℃～0 ℃ " on one side, and wait process on one side water filling is ETAD expected time of arrival and departure again.

CPU is judged as in step S18 and has passed through water filling again during ETAD expected time of arrival and departure, proceeds to step S19.At this, feed water valve 7 is switched to hot water water filling state from the water filling halted state, from the water pipe 10 of feed water valve 7 water pipe 52 and water injecting tank 9 running water is injected in the Storage water tank 3 through compressors 50.Under this state, by carrying out heat exchange between the refrigerant in running water in water pipe 52 and the refrigerant pipe 51 mutually, the running water in the water pipe 52 are heated, thereby implantation temperature is higher than the hot water (hot water injection) of normal temperature in Storage water tank 3.The fin of this condenser 50 is delivered to function running water from refrigerant pipe 51 through water pipes 52 in order to take into account to the function of air heat with the heat of refrigerant, is set in the scope of " 0.1mm～0.15mm ".

According to the foregoing description 3, can play following effect.

After inject handling beginning from hot blast through water filling moment of ETAD expected time of arrival and departure again, the temperature of condenser 50 is injected to handle than hot blast and is become enough high when beginning, when the temperature of condenser 50 becomes enough high, by feed water valve 7 being switched to hot water water filling state, beginning hot water injects to be handled, that is, running water is injected in the Storage water tank 3 through water pipe 52.And then this hot water injects and handles after the beginning, the running water in the water pipe 52 heats up significantly because of the thermal capacity that has absorbed condenser 50 self, is injected in the Storage water tank 3 thereby absorbed the hot water that becomes high temperature after the thermal capacity of condenser 50 self.Therefore, can make water temperature be warmed up to the temperature that is suitable for washing, thereby the ability of cleaning improve.

Be made as and utilize condenser 50 to generate the two structure of hot water and hot blast.Therefore, do not need to add hot tap-water special-purpose split condenser 26, thereby can realize saving spatialization (space-saving) and reducing cost (cost reduction).The water pipe 52 that is made as condenser 50 is arranged in the structure of two row on left and right directions.Therefore, shortened the length dimension of water pipe 52 under deployed condition, thus with feed water valve 7 when hot water water filling state switches to the water filling halted state, in siphonage (siphon effect) water whereabouts in the water pipe 52 down.Therefore, shipwreck to be remaining in the water pipe 52, thereby can prevent to freeze on the inner face of water pipe 52 and get rusty.

The inner face of water pipe 52 is made of even surface.Therefore, can on the part of the inner face of water pipe 52, not produce stress and concentrate, thereby anti-antipriming pipe 52 breaks because of icing causing because of freezing.And, because can residual water at the inner face of water pipe 52, so can prevent also that from this point the inner face of antipriming pipe 52 gets rusty.Because each row that makes water pipe 52 are between the row of refrigerant pipe 51 each other, thus the running water in the water pipe 52 can be efficiently refrigerants in the refrigerant pipe 51 absorb heat.And, as the condenser of condenser 50 use corrugate fin formulas (corrugated fin type).Therefore, the heat conduction efficiency of passing through fin between refrigerant pipe 51 and water pipe 52 improves, thereby makes refrigerant and the running water in the water pipe 52 in refrigerant pipe 51 carry out heat exchange each other efficiently.
