This dishwasher cycle is broadly divided into washing (washing is washed, rinsed comprising master) and two stages of drying.It eats when placing
After the plate-basket 12 of tool 13 is placed in dish washer interior main cavity 14, dish-washing machine starts starting operation.The washing stage is carried out first,
It recycles water injecting pump 8 to start to work, water filling on-off valve 6 is opened, and after injecting a certain amount of water, flow controller 7 will after reading data
It fills the water on-off valve 6 to close, hot water reaches required temperature and sprays into main cavity 14 using spray arm 15 after heating by electric heater 9
Inside is washed, and hot water enters after circulation water injecting pump 8 and electric heater 9 heat up again after the collection of water-carrying groove 11 to wash the dishes
Owner's cavity 14.After constantly recycling washing, the main washing stage washed and rinsed just is completed.When master washes and rinse rank
After the completion of section, draining pump 27 is opened, and the water in sink 11 is discharged to the external world, starts drying course later.
Referring to FIG. 2, Fig. 2 is schematic diagram when dish-washing machine shown in Fig. 1 is in the washing stage, arrow illustrates that air duct in figure
In airflow direction.
As shown, in the washing stage, compressor 22, condenser 23, throttling set 24, the evaporator 20 of heat pump system
It works at the same time, the blower 21 of 20 side of evaporator is opened.Air duct 28 is in outer circulation (air-flow trend such as arrow in air duct at this time
It is shown), third air door 18 and the 4th air door 19 are opened, and the first air door 16 and the second air door 17 are in close state, and refrigerant exists
The evaporation of 20 side of evaporator, absorbs the heat of dish-washing machine outside ambient air.Meanwhile refrigerant in condenser and coming from preheating water
Water in case 3 carries out heat exchange, improves the temperature of water in preheating water tank 3.
Referring to FIG. 3, Fig. 3 is schematic diagram when dish-washing machine shown in Fig. 1 is in drying stage, arrow illustrates that air duct in figure
In airflow direction.
As shown, the water in sink 11 is discharged from draining pump 27, and air door carries out after dish-washing machine washing process
Switching, third air door 18 and the 4th air door 19 are closed, and the first air door 16 and the second air door 17 are opened, and start dish washer interior cavity
Air circulation (the air-flow trend in air duct is as shown by arrows), refrigerant evaporates in evaporator 20, absorbs in dish-washing machine
The heat of the air of portion's main cavity 14 heats the water in preheating water tank 3 in condenser 23.
After drying course, one of dish-washing machine complete circulation (main wash-rinsing-dries) just finishes, into
When entering next circulation, what is carried out first is washing process, therefore air door needs once to be switched again, the first air door 16 and
Two air doors 17 are closed, and third air door 18 and the 4th air door 19 are opened, and blow over evaporator 20 and blower 21 at this time is surrounding air,
Air duct recurrent state returns to state shown in Fig. 2 again.
In addition, the water in preheating water tank 3 is supplemented by water compensating valve 4 since the water in main water box 5 has already consumed by a part
Into main water box 5, since the water in preheating water tank 3 is by heat pump system continuous heating, temperature is higher than the water temperature directly supplemented,
The water directly supplemented from inlet valve 2 generally only has 15 degrees Celsius, and constantly heats by heat pump system condenser, and water temperature can reach
To 30 to 50 degrees Celsius, adding to main water box 5, required temperature (60 can be heated to by only needing to consume a small amount of electric energy later
~80 degrees Celsius), to reduce energy consumption.After completing moisturizing heating and air door switching, dish-washing machine can enter next
The washing process of circulation after the completion of washing process, then carries out air door and switches into drying course, repeatedly, by constantly
Air door switching, dish-washing machine and heat pump drying system can continuously work.
Referring to FIG. 4, Fig. 4 is the structural schematic diagram of another specific embodiment of dish-washing machine provided by the present invention.
As shown, another embodiment eliminates preheating water tank 3 on the basis of above scheme, main water is only used
Case 5, the condenser 23 and main water box 5 of heat pump system form circulation waterway, and the main distinction is the condenser using heat pump system
23 directly heat and keep the temperature the water in main water box 5, and operating process is essentially identical with above content, specifically please refer to above, just
It is not repeated to describe.
It is appreciated that can consume certain electric energy could be in main water box 5 due to being equipped with attemperator inside main water box 5
Water heated, therefore, if dish-washing machine simultaneously be equipped with preheating water tank 3 and main water box 5, the condenser 23 of heat pump system can also
To form circulation waterway with main water box 5, the water in Lai Jiare main water box 5, without forming circulation waterway with preheating water tank 3.
Above-described embodiment is only preferred embodiment of the invention, is specifically not limited thereto, on this basis can be according to reality
It needs to make to have and targetedly adjust, to obtain different embodiments.For example, by air duct be set to main cavity two sides or
Rear portion, alternatively, by Duct design at other shapes, or, the third air door in air duct and the 4th air door are arranged in air duct two
Hold the position etc. at top.Since mode in the cards is more, just no longer illustrate one by one here.
The present invention has used a set of heat pump system in bell-type commercial dish-washing machine drying course, improves drying efficiency, and
The preheating that heat recovery is got up to be used for next cycling use of water, improves energy utilization rate；Meanwhile in dish-washing machine air duct side
Air door handover scheme has been used, has enabled heat pump system other than drying stage work, also can utilize the external world in the washing stage
Air works on, so as to further be preheated to recirculated water, heat source (the damp and hot sky of dish washer interior cavity from two
Gas and external environment atmosphere) preheating of the heat absorption for use in dishwasher water, a big chunk electric heating power consumption can be saved, thus
Substantially reduce power consumption.
Dish-washing machine provided by the present invention is described in detail above.Specific case used herein is to the present invention
Principle and embodiment be expounded, the above description of the embodiments is only for helping to understand the core idea of the present invention.
It should be pointed out that for those skilled in the art, it without departing from the principle of the present invention, can also be right
Some improvement and modification can also be carried out by the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
