The invention relates to the technical field of household electrical appliances, and especially relates to a dish-washing machine water saving method, comprising a water softening apparatus. The water softening apparatus comprises a salt chamber used to store saturated salt water, and a resin chamber used to store resin. A pipe communicates the salt water and the resin chamber. The pipe is provided with a one-way valve. The method is characterized in that through comparing accumulated water inflow Q1 entering the resin chamber with a regeneration rated value Q set by the water softening apparatus, whether to control the water softening apparatus to perform regeneration operation or not is determined according to a comparison result. Also disclosed is a dish-washing machine which uses the dish-washing machine water saving method. Regeneration after a washing process each time of a conventional dish-washing machine is changed into an independent regeneration program module, and when water inflow of the dish-washing machine reaches the rated value of the water softening apparatus, the regeneration is performed, so as to achieve an objective of reducing water consumption of the dish-washing machine.

Example Embodiment

[0020] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0021] like image 3 As shown, a water-saving method for a dishwasher includes a water softener, the water softener includes a salt chamber for storing saturated brine and a resin chamber for storing resin, and the salt chamber and the resin chamber There is a pipeline connected to it, and a one-way valve is set on the pipeline. The method is to compare the accumulated water intake Q1 entering the resin chamber with the regeneration rating Q set by the water softener, and judge whether to control the water softening according to the comparison result. The device performs regeneration operation.
[0022] The concentrated saline solution stored in the salt chamber is used to replace the calcium and magnesium ions in the resin chamber, and the salt chamber and the resin chamber are connected and isolated through a one-way solenoid valve.
[0023] Specifically, the initial value of the cumulative water intake Q1 is Q0, and the cumulative water intake Q1 will be every time after the cumulative water intake Q1 is equal to Q0 and before the next cumulative water intake Q1 is restored to the initial value Q0 The cumulative value of the water inflow of the resin chamber is accumulated.
[0024] If the accumulative water inflow Q1≥regeneration rated value Q, the water softener performs regeneration operation; if Q1
[0025] The value of the regeneration rating Q can be a fixed value, or it can be adjustable, because different regions and different water sources have different hardness of the water bodies, and the corresponding regeneration ratings are also different. When installing or using for the first time, regeneration The setting of the rated value Q needs to be set by the user according to the local water hardness and according to the recommended setting range in the manual when the machine is turned on for the first time.
[0026] Preferably, a basic regeneration rating Q is set in the factory settings, and the user can set the value of the regeneration rating Q by himself through the control buttons on the control panel according to the hardness value of the local water after starting the machine.
[0027] Alternatively, for the convenience of the user, Q value selection keys for different water hardnesses can also be set on the operation panel of the dishwasher, and the user can select the regeneration rating Q corresponding to the water hardness used by pressing the Q value selection key.
[0028] The accumulated water intake Q1 can be obtained through the flowmeter installed in the water intake pipeline.
[0029] Alternatively, the accumulative water intake Q1 can be obtained through the control unit of the dishwasher, the water level switch and the water intake valve connected to the control unit.
[0030] The present invention also provides a dishwasher, which adopts the above water-saving method for the dishwasher.
[0031] During specific implementation, reassigning the accumulated water intake Q1 to Q0 is the end of a water-saving regeneration program cycle, and then the next cycle begins. The value of the accumulated water intake Q1 is not affected by the completion of washing and the shutdown or Reboot clears.
[0032] The following is a relevant comparison for specific test data:
[0033] The single water consumption of the traditional dishwasher washing program is 12L, of which 1.5L of water is consumed for each flushing of salt, calculated according to 280 cycles per year, and the annual water consumption is 12*280=3360L.
[0034] During specific implementation, the regeneration rating of the water softener is set to Q=60L. For the dishwasher using the dishwasher water-saving method program, when the dishwasher executes the washing program, the water consumption (excluding flushing salt) is 10.5L, after five wash programs to reach the regeneration rating of the water softener Q.
[0035] At this time, if the difference N between Q1 and Q is 0, the water softening and regeneration program will be started, and the single flushing of salt will consume 1.5L of water, that is, the water consumption of the first four programs will be 10.5L, and the fifth time will consume 12L. The levels are all (10.5*4+12)/5=10.8L.
[0036] Calculated according to 280 cycles per year, the annual water consumption is 10.8*280=3024L, which can save 336L of water per year compared with the traditional dishwasher water soft regeneration program.
[0037] To sum up, the regeneration of the traditional water softener needs to be carried out at the end of each dishwasher program. At this time, the water softener is not saturated, and the dishwasher consumes 1-2L of water for each regeneration action, resulting in The water consumption of the whole machine is relatively high.
[0038] The invention sets the regeneration rated value Q of the softened water quantity of the used water softener and a separate regeneration program module in the computer board during design, and executes the regeneration of the water softener when the softened water quantity Q1 of the water softener reaches the upper limit of the Q value. The regeneration rating Q value of the water softener used in the dishwasher is set to 60L, and the regeneration is usually performed only after 5 dishwasher programs, which greatly reduces the water consumption of the dishwasher.
[0039] The above describes the technical principles of the present invention in conjunction with specific embodiments. These descriptions are only for explaining the principles of the present invention, and cannot be construed as limiting the protection scope of the present invention in any way. Based on the explanations herein, those skilled in the art can think of other specific implementation modes of the present invention without creative efforts, and these modes will all fall within the protection scope of the present invention.
