Description

A kind of dish-washing machine and its washing methods preventing residual water
Technical field
The present invention relates to cleaning implement for kitchen technical field, more particularly to one kind can prevent residual water dish-washing machine and its Washing methods.
Background technique
The draining of existing dish-washing machine be by the drainage system of pedestal by sewage after draining pump is drawn into drainage pipeline, work as row When water pump stopping acts, the water in drainage pipeline is not discharged into floor drain all, is led to remain in the water in drainage pipeline and is back to In liner water collection chamber (cup).For a long time in this way, residual sewage Yu Shuihou easily generates mildew, breeds bacterium, is unpleasant in dish-washing machine Peculiar smell.Such case not only increases wash the dishes after workload, and serious waste time, influence user experience.
In view of this, this invention is just improved in drainage system mode, a kind of remain convenient for solution liner is provided and is washed Effluent problem is washed, dish washer interior more clean hygiene is made, user improves user experience without carrying out cumbersome cleaning.
Summary of the invention
To solve the problem of that above-mentioned dishwasher drain pipe road sewage backflow causes to remain wash water in Water cup of dish-washing machine, The present invention provides dish-washing machines and its washing methods that one kind can prevent residual water.
To achieve the above object, The technical solution adopted by the invention is as follows: one kind can prevent the dish-washing machine of residual water, including Cabinet and cup positioned at cabinet, and the gushing arm positioned at cup top, water feed apparatus and drainage arrangement;The drainage arrangement includes The draining pump and the first coupled drainage pipeline, first drainage pipeline other side and respirator of cup side are set Anti- siphon component is connected, and the respirator anti-siphon component other side is connected with the second drainage pipeline.
Further, the drainage arrangement further includes valve, valve setting draining pump and the first drainage pipeline it Between.
It further, further include water softener, the water feed apparatus includes the first water inlet line and the second water inlet line, described First water inlet line is connected with respirator, and the respirator is connected by the second water inlet line with water softener, the water softener Rear end is provided with washing pump, and the washing pump is connected with cup by the second water inlet line.
Further, the water feed apparatus further includes flowmeter, and the flowmeter is arranged in respirator interior.
Further, the cup side is additionally provided with water level pressure switch.
A kind of dish-washing machine washing methods preventing residual water, the dish-washing machine washing methods successively include washing preceding cup Cup after cleaning procedure, dish-washing machine washing procedure, drainage procedure and washing cleans four steps again:
(1) cup cleaning procedure before washing: before dish-washing machine is started to work, a sewage treatment is carried out first, passes through water inlet Device starts to intake, flowmeter start recording flow of inlet water, and sets flooding time according to the size of flow of inlet water, works as inflow When meeting the requirements, opens draining pump and solenoid valve works together, cup is once cleaned;
(2) dish-washing machine washing procedure: after the completion of cup cleaning, washing procedure is opened, tap water enters soft water by water inlet pipe Device enters in cup after softening, inflow is determined by flowmeter, and set flooding time, while according to water level switch pair Water level is measured in real time, and when water level, which reaches satisfaction washing, to be required, starts to wash;
(3) drainage procedure: opening draining pump, open simultaneously solenoid valve, drained, and carries out low water level detection to cup, In the case where low water level, draining pump works on, and is then turned off valve, and subsequent draining pump stops working;
(4) cup cleaning procedure after washing: after the completion of washing of washing the dishes, then cup is once cleaned according to step (1).
Further, steps are as follows for cup cleaning procedure before the washing: after entering respirator by the first water inlet line, Flowmeter counting turns off inlet water solenoid valve after reaching water consumption;Determine that flooding time M, washing water are entered by the second water inlet line Enter cup after water softener softening, air pressure constantly increases in cup, when pressure reaches the height of water level of cleaning setting, is connected in water Water level pressure switch on cup disconnects first, and then draining pump and valve opening are connected to the first drainage pipeline with cup to be arranged Water excludes residual sewage in dish-washing machine after acting T seconds.
Further, the dish-washing machine washing methods is as follows: after dish-washing machine washing work starts, again through the first water inlet After pipeline water filling enters respirator, flowmeter counting turns off inlet water solenoid valve after reaching water consumption, determines flooding time N, washs After water enters water softener softening by the second water inlet line, water flow enters air pressure in cup and constantly increases, when pressure reaches washing When the height of water level of setting, the water level pressure switch on cup is closed, and washing pump, which is started to work, opens water inlet, washed pump pressurization Water afterwards from gushing arm ejection water column suitable for reading, directly wash away tableware or be sprayed onto rebound indirect erosion tableware behind inner cavity by water flow, washes It washs sewage and flows into cup 4.
Further, steps are as follows for the draining prologue: when drainage works open when, wash water by cup row It after water pump, valve are opened, is connected to the first drainage pipeline, draining pump carries out drainage works;Wash water passes through the anti-rainbow of respirator It inhales function to be discharged by the second drainage pipeline, until after water level pressure switch detects low water level signal, draining pump continues after S seconds Work T seconds, valve shutdown, then draining pump stops working.
Further, flooding time N is greater than for cup cleaning flooding time before washing in the dish-washing machine washing procedure N。
Further, draining pump operation time described in cup cleaning procedure is greater than valve opening time after the washing.
Further, in drainage procedure, after water level pressure switch detects low water level signal, draining pump works on T model It encloses are as follows: 30s≤T≤120s.
Further, in drainage procedure, after water level pressure switch detects low water level signal, the draining pump T that works on is 60s。
By the above-mentioned description of this invention it is found that compared with prior art, the present invention by change drainage system structure and Water discharge method, to prevent remaining water residual in dish-washing machine, water conservancy project is made more than reduction cleaning heavy after washing the dishes, in effectively preventing liner Cause to breed bacterium, unpleasant peculiar smell etc. there are remaining water, to improve user experience.
