For having further understanding to structural feature and effect thereof of the present invention, enumerate specific embodiment and describe in detail as follows:

A fully automatic washing machine with the above water-saving function selected, the fully automatic washing machine includes: a box body, a control panel seat arranged on the box body, a computer control panel in the control panel seat, a water inlet valve, etc., the control panel There are washing, rinsing, draining, and dehydration programs on the seat, which are the same as the existing fully automatic washing machine, so the structural diagram of the fully automatic washing machine is omitted in this manual. The only difference is: the control panel seat is further equipped with useful It is used to control the water reservation selection button for washing water or rinsing water. As shown in Figure 1, it is a schematic diagram of the panel structure of the water-saving washing machine of the present invention. The panel 1 in the figure includes two parts: a display part and a control button. The display part adopts a combination of a transparent window 11 and a light-emitting indicator light 12 It can also be displayed by means of light-emitting indicator lights. The transparent window 11 mainly displays water level and water volume, washing time, and remaining time of appointment. The light-emitting indicator light 12 mainly displays washing procedures: such as: commonly used procedures, Standard program, memory program, fast program, soaking program, cotton program, wool program, barrel drying program, in the present invention, the luminescent indicator light 12 is also used to indicate whether to choose the water retention program, and the corresponding first rinse Display, 2 times of rinsing display, 3 times of rinsing display; the control button part adopts a light touch switch or a touch switch in the present invention, and a touch switch 13 is used in the present invention, wherein the control program selection includes: program selection button, washing selection button , Rinsing selection button, dehydration selection button, appointment selection button, water level selection button, water retention selection button, start/pause button and power on/off button. Generally speaking, the panel of the washing machine of the present invention is substantially the same as the control panel of the existing fully automatic washing machine, and has normal washing, rinsing, draining, and dehydration program keys, the only difference being that the control panel of the water-saving washing machine of the present invention A water retention selection button is added on the top, the water retention button is mainly to make an appointment to set the temporary storage/recovery of rinse water before starting the selected washing and/or program, and the program is mainly not carried out temporarily after the washing and/or rinsing is completed. Drainage, buzzing and the corresponding recovery rinse water indicator flashing to remind the user, each alarm 20 times (20S), beeping once every 5 minutes (20 times), stop timing during the waiting process (waiting time can not be counted in the whole program time, calculated separately), if the waiting time exceeds 15 minutes without action, the buzzer will be automatically released, and the washing machine will directly switch to the next step after the alarm beeps, and the water will be drained and the water will be discharged directly from the washing bucket; if the waiting time The user can open and close the cover once or press the start button to start the washing machine drainage function, and the water will be discharged into the container designated by the user to recycle the washing water or rinsing water. the

In addition, the user can also choose to recover multiple rinse waters according to needs, and at the same time, for the situation of selecting multiple rinses, the indicator light on the display panel displays the selected corresponding rinse water. the

Below in conjunction with Fig. 2, Fig. 3, Fig. 4, the water-saving washing machine of the present invention retains the rinsing water procedure to illustrate:

As shown in Figure 2, when the program is set, first start to open the power setting program 20, then judge whether there is a rinse program 21 to be selected, if so, execute the judgment step 23 of the number of rinse times, if the rinse program is not selected, then the execution cannot be performed. Set step 22 of recovering rinse water, and return; Next, in step 22, it is judged that the number of rinses is single or multiple, if you choose to recover 1 rinse water, then execute subroutine A, if you choose to recover 2 times or 2 If there is more than one rinse water, execute subroutine B. It is explained here that the single rinse water refers to the first rinse water or the second rinse water or the third rinse water, and the multiple rinse water refers to the recovery of at least two rinse water, which can be the first and second rinse water. The rinse water for the second rinse may also be the rinse water for the second rinse and the rinse water for the third rinse, or all the rinse water for the third rinse may be recovered. the

As shown in Figure 3, it is a flow chart of the subroutine A of recovering single rinse water in the water-saving washing machine of the present invention, step 30, rinsing finishes, and starts to enter the recovery program, step 31, judges whether the Nth rinsing is finished, if finished, Execute step 32, if it is not over, continue rinsing; step 32, judge whether it is necessary to recover the rinsing water, if necessary, perform step 33, if not, directly execute step 35 of draining; step 33, enter the drainage pause and alarm prompt Recover the water, wait for the drainage start signal, wait for the timing to start, and then execute step 34 to judge whether the waiting timing has reached 15 minutes. If the drainage signal is still not given after 15 minutes, then execute step 35 to start automatic drainage. In the time period of 15 minutes, execute judgment step 36 again to judge whether to receive the drainage start signal, if received, execute step 35, start drainage, if not received, then return to step 34, continue to wait for timing, so, single The second draining program ends. Among them, the Nth time in step 31, generally N represents a natural number 1 or 2 or 3, the drainage start signal in step 36 means that the user opens and closes the cover once or presses the start button once, when the user actively recovers the rinse water , the subroutine ends, and the electric control board continues to execute the follow-up program. Wherein, the core chip model in the computer control panel can adopt the 14021 series chips produced by Panasonic Corporation of Japan, such as: IC14021WFW, or adopt the MCS-48 series chips produced by Intel Corporation, such as 8049, 8035, 8020, etc. the

As shown in Figure 4, it is a flow chart of the subroutine B for recycling multiple rinsing water in the water-saving washing machine of the present invention. Step 40 is the rinsing process. After the rinsing is completed, the recovery program starts. Step 41 determines whether the first rinsing is over. If it is not over, continue rinsing, if it is over, then execute step 42, call the subroutine A of single draining, after executing the program A; execute step 43, finish the draining, start the second rinsing, step 44, judge the first Whether the 2 times of rinsing is over, if not, continue rinsing, if it is over, then execute step 45, and then call the subroutine A of single draining, after executing program A; continue to execute step 46, draining is over, start the third step Second rinsing, step 47, judge whether the 3rd rinsing is over, if not over, continue rinsing, if end, then perform step 48, call the subroutine A of single drainage for the 3rd time. It can be seen from FIG. 4 that recycling multiple rinsing water is mainly to repeatedly call the program of recovering single rinsing water, and execute different program steps according to the requirements selected by the user to recycle different times of rinsing water. the

Generally speaking, when the user uses, after selecting the laundry program, before starting the washing program, press the "reserve water" reservation button to select "reserve washing water" or "reserve the first rinse water" or "reserve the second rinse water". "or "reserve the third rinse water". The washing machine executes the selected laundry program until the washing or the first rinse or the second rinse or the third rinse is completed. The next step of the draining program is not performed, but a buzzer prompts. Press the start button or open the washing machine cover once. The washing machine will either drain or continue with the selected programme. the

Example 1
