Then, with reference to Fig. 7～Figure 10, the control action (in detail for the process starting to matting) carried out in this washing machine 1 is described。Additionally, the display content of the display part 4 illustrated in Figure 10 in control action。The display part 4 of (before switching on power) does not have before washing machine 1 operating any display (the display part 4A with reference to Figure 10)。

First, with reference to Fig. 7, as the operation start of washing machine 1, by the operation of user power key 25 opened after thereby turning on power supply (step S1), show initial picture (the display part 4B with reference to Figure 10) on the display section 4。Then, when pressing washing key 27 or dry key 28 thus option program (herein as an example, only carry out the program of washing procedure) of washing as user, microcomputer 51 by this program display at display part 4 (the display part 4C with reference to Figure 10)。And, when user carries out when setting in detail of contents of program by each setting key 32～35 and setting rotating disk 36 (with reference to Fig. 5), the content of setting is shown in display part 4 (the display part 4D with reference to Figure 10) by microcomputer 51。

Now, when user press reheating key 37 select to reheat temperature time, microcomputer 51 by the reheatings temperature selected, selection reheatings temperature conditions under need in matting add the described reference time (being stored in ROM52) expended and be shown in display part 4 the display part 4E of Figure 10 (reference)。When display part 4E, reheating temperature and be about+15 DEG C, the reference time is about+45 minutes。

Additionally, in this condition when user presses and informs key 31, microcomputer 51 with reference to the storage content of memorizer 60 by the water temperature before the reheating temperature in the matting in previous washing, the heating in previous purge operation, in this water temperature, add the water temperature (the previous water temperature after the heating in matting) reheated after temperature be shown to display part 4 (the display part 4F with reference to Figure 10)。When display part 4F, the reheating temperature in previous washing is about+15 DEG C, and the water temperature before heating in previous purge operation is about 15 DEG C, and the water temperature after heating in previous purge operation is about 30 DEG C。Information about these temperature is called " previous operating content "。

Afterwards, when user operation start key 26 turns on (step S2), microcomputer 51 starts to measure the load capacity (step S3) of the washings in sink 50。Specifically, microcomputer 51 applies certain electric power to rotating cylinder 7, rotation cylinder 7 is made first to rotate with rotating speed (such as 65rpm) to a certain degree, thereafter electric power keeps under certain state, rotating speed is promoted to such as 140rpm, makes medicated clothing attach to the inner peripheral surface rotating cylinder 7。Then, according to by not shown timer measuring, rotating speed rise to the time needed for 140rpm from above-mentioned 65rpm, measure the amount (washing amount) putting on the load capacity rotating cylinder 7, being namely housed in the washings rotated in cylinder 7。It is relevant that load capacity washs required detergent amount to washings, therefore the period in load capacity is measured, the content in detergent amount (or aforesaid washing amount) measurement is shown to display part 4 (the display part 4G with reference to Figure 10) by microcomputer 51。

Afterwards, microcomputer 51 judges the load capacity of washings according to the measurement result in step S3, and judges required detergent amount (step S4) according to this load capacity。Additionally, detergent amount herein pre-determines according to load capacity, it is stored in ROM52。The detergent amount of judgement is shown to (step S5) after display part 4 (the display part 4H with reference to Figure 10) by microcomputer 51, waits that user is to putting detergent (step S6) in sink 50。

After detergent amount is shown to display part 4 (the display part 4H with reference to Figure 10) when 1 minute (in the step s 7 "Yes"), microcomputer 51 confirms whether user operates reheating key 37 to open (step S8)。

If even across 1 minute, user is also without carrying out reheating the operation (unlatching) (in step s 8 "No") of key 37, microcomputer 51 opens feed water valve 56 when closing drain valve 57, and by this secondary program (when this embodiment, relate to the operating of the washing machine 1 of washing procedure) all terminate till required remaining time (remaining time when not using hot water is called " initial residual time ") be shown to display part 4 (the display part 4I with reference to Figure 10) (step S9)。Remaining time calculates in advance by load capacity within each program and is stored in ROM52, and microcomputer 51 obtains the remaining time corresponding with the load capacity judged in step s 4 in step s 9 from ROM52, is shown to display part 4。

After showing remaining time, microcomputer 51 starts matting。When this program all terminates, this content is shown to display part 4 (the display part 4J with reference to Figure 10) by microcomputer 51。

On the other hand, user will reheat (in step s 8 "Yes") when key 37 operates as opening, and microcomputer 51 received the selection of the reheating temperature of user before starting washing (matting)。Reference time corresponding to the reheating temperature (user presses the reheating temperature corresponding to the number of times reheating key 37) selected and this reheating temperature is shown to display part 4 (the display part 4K with reference to Figure 10) (step S10) by microcomputer 51。

Display part 4 shows reheating temperature and reference time, when user will inform that key 37 operates as opening (in step s 11 "Yes"), aforesaid previous operating content is shown to display part 4 (the display part 4L with reference to Figure 10) (step S12) by microcomputer 51。That is, microcomputer 51 is according to the operation informing key 37 (operating portion 5), previous operating content (the reheating temperature selected when including previous washing) being shown to display part 4。Thus, user select reheat temperature time can with reference to display part 4 in display previous reheating temperature, therefore can improve convenience in washing machine 1。After the previous operating content of display when stipulated time (such as several seconds), the display of display part 4 is automatically switched, it is possible to again shows and reheats temperature and reference time (the display part 4K with reference to Figure 10)。

When in step s 12 previous operating content being shown to display part 4, or do not operate when informing key 37 (in step s 11 "No") in step s 11, that is when pressing reheating key 37 at least in step s 8, microcomputer 51 performs following hot water and controls (step S13)。It addition, perform when hot water controls as referring to the time obtained on the aforesaid initial residual time the initial remaining time (being called " benchmark remaining time ") of benchmark plus (corresponding to the reheating temperature that the user selects) reference time pressed in step S8 corresponding to the number of times reheating key 37。Strictly, benchmark refers to the time needed for beginning to warm up water all terminates from hot-water heater 9 to this secondary program (here for washing procedure) remaining time。Benchmark when pressing reheating key 37 every time, can be calculated by microcomputer 51 according to aforementioned sequence remaining time。It addition, benchmark remaining time can also be corresponding with each reheating temperature by load capacity (in other words each water level according to load capacity) and be stored in ROM52。That is, in ROM52, storage has when the reheating temperature that load capacity (or at the required water level of the washing of this load capacity) is certain value, selection is the several years benchmark remaining time be how many。

As the ring that hot water controls, with reference to Fig. 8, first microcomputer 51 is opened feed water valve 56 when closing drain valve 57 and is started to supply water (step S21) to sink 50。Then, microcomputer 51 starts to measure room temperature according to temperature sensor 54 and measure water temperature (from the temperature of the tap water that feed water valve 56 supplies to sink 50) (step S22) according to cooling-water temperature sensor 24 in water supply process。Now, the content in temperature measurement is shown to display part 4 (the display part 4M with reference to Figure 10) (step S23) by microcomputer 51。

Afterwards, microcomputer 51 is according to level sensor 53 monitors by for whether the water level in water washing groove 50 reaches measurement water level (step S24)。The water that the washings measured in the water level and sink 50 that water level refers to that hot-water heater 9 is totally submerged herein fully absorbs in sink 50 is then at the water level of the steady statue state of water (washings cannot continue to absorb)。

When the water level in sink 50 arrives and measures water level (in step s 24 "Yes"), microcomputer 51 stops supplying water, according to this time point, (water level arrives the time point measuring water level, hereinafter referred to as " current point in time ") in temperature sensor 54 and the respective measurement result of cooling-water temperature sensor 24, it is determined that the room temperature of current point in time and water temperature (step S25)。

Afterwards, microcomputer 51 performs following Corrective control remaining time (step S26)。

A ring as Corrective control remaining time, with reference to Fig. 9, microcomputer 51 judges that the room temperature that judges in step s 25 is whether as less than 15 DEG C (step S31), if room temperature is less than 15 DEG C (in step S31 "Yes"), then determine whether whether room temperature is less than 5 DEG C (step S32)。If room temperature is less than 5 DEG C (in step s 32 "Yes"), then microcomputer 51 calculates X correction time (unit for minute) according to below formula (1), judge to add correction time (step S33) of X minute to remaining time (aforesaid benchmark remaining time), return original hot water and control。If room temperature is below 15 DEG C but higher than 5 DEG C (in step s 32 "No"), then microcomputer 51 calculates Y correction time (unit for minute) according to below formula (2), judge the correction time (step S34) to additional Y minute of remaining time (benchmark remaining time), return original hot water and control。

X=2 × reheating temperature ... formula (1)

Y=1 × reheating temperature ... formula (2)

Additionally, if room temperature is higher than 15 DEG C, (in step S31, " no "), microcomputer 51 will be set to 0 (zero) termination Corrective control remaining time correction time, return original hot water and control。

Return Fig. 8, remaining time after remaining time (benchmark remaining time) adds the correction obtained by correction time that remaining time, Corrective control was determined, when terminating Corrective control remaining time, is shown to display part 4 (the display part 4I with reference to Figure 10) (step S27) by microcomputer 51。

As implied above, when microcomputer 51 have received the selection reheating temperature in step s 8, remaining time (benchmark remaining time or added time of correction time on benchmark remaining time) is shown to display part 4 (step S27), wherein, described remaining time is: in the hot water of step S13 controls, the water in sink 50 is heated for making it only to rise reheating temperature until washing terminates the required time from the water temperature of the current point in time of cooling-water temperature sensor 24 detection by hot-water heater 9。

That is, in washing machine 1, about adding hot water to generate hot water, what received before starting washing is not the selection of the target temperature (hot water temperature after heating) of hot water, but receives the selection (step S8) of the temperature (reheating temperature) added from the water temperature of current point in time。

In this case, according to the reception of selection reheating temperature, obtain rapidly water in sink 50 from the water temperature of current point in time heated and till the reheating temperature that only rises and wash and terminate required remaining time, and display it to display part 4。In addition, remaining time herein can be precalculate and be stored according to each selectable reheating temperature (here within the scope of+0 DEG C～+45 DEG C every 5 DEG C) in ROM52, it is also possible to is calculated by microcomputer 51 (according to the water level measured, room temperature and water temperature) whenever selecting to reheat temperature。No matter select which kind of mode, even if the temperature as the cold water (being tap water but it also may be water for bathing) of hot water source herein changed along with season, also more accurate than the remaining time of based target temperature based on the remaining time reheating temperature。

According to above result, in the washing machine 1 of the structure using hot water to carry out washing, it is possible to accurately grasp remaining time。

Additionally, the temperature (room temperature) of the current point in time that temperature sensor 54 detects for uniform temperature (being 15 DEG C or 5 DEG C in the present embodiment) below when, microcomputer 51 the remaining time of step 26 remaining time (benchmark remaining time) is corrected by Corrective control (than room temperature higher than uniform temperature time remaining time) longer。That is, when temperature around washing machine 1 is below uniform temperature, consider that the water temperature of current point in time only rises and more take time (rising of water temperature is slow) than usual till reheating temperature, to correct remaining time longer, and therefore can grasp remaining time more accurately in washing machine 1。Additionally, in remaining time Corrective control, use aforesaid formula (1) or (2) to calculate correction time。Replace, additional time of (more than 0 DEG C less than 5 DEG C every each scope of 5 DEG C) every 1 DEG C be stored in ROM52 in can also presetting each room temperature range, the value obtained the additional time corresponding to the room temperature being multiplied by current point in time by the difference of benchmark room temperature (average room temperature) Yu the room temperature of current point in time is as correction time。

Under the state in step s 27 remaining time after correction being shown to display part 4, it is set to user and presses reheating key 37。In this situation, reheating temperature that user is selected by microcomputer 51, the water temperature (water temperature judged in step s 25) of current point in time, the water temperature of the current point in time detected by cooling-water temperature sensor 24 adds the temperature (water temperature after heating, hereinafter referred to as " target temperature ") reheating temperature and obtain it is shown to display part 4 (the display part 4N with reference to Figure 10)。When display part 4N, reheating temperature and be about+15 DEG C, the water temperature (current water temperature) of current point in time is about 15 DEG C, and target temperature is about 30 DEG C。Thus, user can pass through display part 4 master goal temperature, therefore can improve convenience in washing machine 1 further。" this content that operates " will be called with the information of these temperature correlations of display in display part 4N。It addition, user can also pass through to press reheating key 37 further again changes reheating temperature, recalculate remaining time (benchmark remaining time and the benchmark remaining time after correction)。If it addition, user presses and informs key 31 when showing this operating content in display part 4, previous operating content is then shown to display part 4 (the display part 4P with reference to Figure 10) by microcomputer 51。

And, after microcomputer 51 starts to show remaining time in step s 27 (above-mentioned recalculate when), as heating process, drive hot-water heater 9, the water in sink 50 is heated till water temperature only rises and reheats temperature (till arriving target temperature) (step S28)。Additionally, in heating process, so that the water temperature in sink 50 will not have deviation due to position difference, microcomputer 51 regularly makes rotation cylinder 7 rotate。

When the water temperature in sink 50 only rise reheating temperature reach target temperature time, including heating process whole hot water control terminate, microcomputer 51 starts matting as shown in Figure 7。

The present invention is not limited to embodiments described above, can carry out various change in the scope described in claim。

Such as, if aforesaid target temperature exceedes predetermined ceiling temperature (such as 50 DEG C), remaining time can be corrected shorter so that this target temperature becomes below ceiling temperature by microcomputer 51。Specifically, as an example of correction, can enumerate driving time (in other words the heat time heating time of water) the mandatory shortening stipulated time of hot-water heater 9。By so correcting remaining time, it is possible to the high temperature more than needed for making (add in the water temperature of current point in time and reheat temperature and obtain) target temperature to become, convenience therefore can be improved in washing machine 1 further。
