Background technology
At present, domestic bowl-washing generally all needs the heated scrub water, in order to guarantee cleaning and drying capacity of dish-washing machine.Wash the stage main, washing water temperature is heated to and surpasses 48 ℃, can washings be discharged dish-washing machine when this stage wash finishes, and the water temperature of this moment is still more than 43 ℃; And then water inlet, the inflow temperature of this moment is generally lower, need be heated to once more more than 60 ℃, and the heat energy that high-temperature water contained that the main stage of washing is discharged dish-washing machine is wasted fully.
Summary of the invention
In order to address the above problem, the utility model provides a kind of heat-exchanger rig of dish-washing machine, through this heat-exchanger rig, the water inlet of the lower temperature of entering is drawn be about to the heat energy in the high-temperature water of discharging dish-washing machine.
The technical scheme of the utility model is: a kind of heat-exchanger rig of dish-washing machine comprises cold water inlet and is located at the water intaking valve on the cold water inlet; It is characterized in that also comprising the water tank, circulating water inlet, radiator drain, shunt valve, tube connector and the magnetic valve that are located in the dish-washing machine housing; Wherein in said water tank, be provided with the heat release passage and can absorb the heat recipient passage of heat release passage heat, the heat release passage is not communicated with heat recipient passage mutually; The delivery port of said circulating water inlet communicates with the water inlet of heat release passage, and a delivery port of the water inlet shunt valve of circulating water inlet communicates; The delivery port of said cold water inlet communicates with the water inlet of heat recipient passage; Said radiator drain has two water inlets, and a water inlet communicates with the delivery port of heat recipient passage, and said magnetic valve is located in this water inlet, and another water inlet communicates with the delivery port of heat release passage, and the delivery port of radiator drain communicates with the water tumbler of dish-washing machine; Said tube connector one end communicates with water tumbler, and the other end communicates with the delivery port of shunt valve through the washing pump of dish-washing machine.
Said heat release passage comprises being located at goes into tank, delivery box and the heat exchanger tube more than two in the water tank, and an end of wherein said heat exchanger tube communicates with going into tank, and the other end communicates with delivery box; The delivery port of said circulating water inlet communicates with going into tank, and a water inlet of said radiator drain communicates with delivery box; Said heat recipient passage comprises the heat exchange tank that is located in the water tank, and said heat exchanger tube is located in the heat exchange tank, and said cold water inlet communicates with the water inlet of heat exchange tank, and another water inlet of said radiator drain communicates with the delivery port of heat exchange tank.
The utility model effect compared with prior art is: dish-washing machine is in when operation, the water inlet of lower temperature absorbed be about to the heat energy in the high-temperature water of discharging dish-washing machine, effectively reduces the energy consumption of dish-washing machine.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1,2, shown in 3, a kind of heat-exchanger rig of dish-washing machine comprises cold water inlet 10 and is located at the water intaking valve 8 on the cold water inlet 10; The utility model characteristics are also to comprise water tank 1, circulating water inlet 5, radiator drain 3, shunt valve 4, tube connector 61 and the magnetic valve 2 that is located in the dish-washing machine housing; Wherein in said water tank 1, be provided with the heat release passage and can absorb the heat recipient passage of heat release passage heat, the heat release passage is not communicated with heat recipient passage mutually; The delivery port of said circulating water inlet 5 communicates with the water inlet of heat release passage, and a delivery port 41 of the water inlet shunt valve 4 of circulating water inlet 5 communicates; The delivery port of said cold water inlet 10 communicates with the water inlet of heat recipient passage; Said radiator drain 3 has two water inlets, and a water inlet communicates with the delivery port of heat recipient passage, and said magnetic valve 2 is located in this water inlet, and another water inlet communicates with the delivery port of heat release passage, and the delivery port of radiator drain 3 communicates with the water tumbler of dish-washing machine 6; Said tube connector 61 1 ends communicate with water tumbler 6, and the other end communicates with the delivery port 41 of shunt valve 4 through the washing pump 7 of dish-washing machine.
In the present embodiment, said heat release passage comprises being located at goes into tank 11, delivery box 14 and the heat exchanger tube more than two 13 in the water tank 1, and an end of wherein said heat exchanger tube 13 communicates with going into tank 11, and the other end communicates with delivery box 14; The delivery port of said circulating water inlet 5 communicates with going into tank 11, and a water inlet of said radiator drain 3 communicates with delivery box 14; Said heat recipient passage comprises the heat exchange tank 12 that is located in the water tank 1; Said heat exchanger tube 13 is located in the heat exchange tank 12; Be provided with eight heat exchanger tubes 13 in the present embodiment; The bar number of heat exchanger tube 13 can confirm that said cold water inlet 10 communicates with the water inlet of heat exchange tank 12 according to the size of heat exchange tank 12 and the caliber of heat exchanger tube 13, and another water inlet of said radiator drain 3 communicates with the delivery port of heat exchange tank 12.
The operation principle of this utility model is: when the master of dish-washing machine closes to an end in the stage of washing, and water intaking valve 8 actions, the next stage, clean slurry got in the heat exchange tank 12, and magnetic valve 2 state that keeps shut is temporarily stored in the heat exchange tank 12 clean washings.This moment in the main stage of washing finishes, and the water outlet of shunt valve 4 action control washing pumps 7 is only gone into tank 11 along delivery port 41 through circulating water inlet 5, again by heat exchange road 13 in delivery box 14; After carrying out heat exchange in the clean slurry heat exchange tank 12 of next stage; Washing pump 7 quits work, and draining pump 9 is started working, and recirculated water is discharged in dish-washing machine; After finishing the work, draining pump 9 closes; Magnetic valve 2 actions, the water after being heated gets in the water tumbler 6 through radiator drain 3, carries out the washing work of next stage.
If the washing sequential of dish-washing machine has repeatedly washing heating, above-mentioned course of action can repeat into.
