The specific embodiment
As shown in Figure 2, the laundry dryer of the condensed water discharge portion 30 of the embodiment of the invention is the dryer of general condensing mode.It is provided with condensed water discharge portion 30 to the outside blast pipe 18 ' inside of discharging air of laundry dryer.
In order to flow into the cooling fan 20 of extraneous air to above-mentioned condenser 13, the air that driving by said structure causes flows, make the condensed water discharge portion 30 that is arranged at blast pipe 18 ' that air take place and flow, in above-mentioned air flows, can obtain to discharge naturally the energy of condensed water.
Referring to Fig. 3 a, Fig. 3 b, Fig. 3 c, the detailed structure of above-mentioned condensed water discharge portion 30 and condensed water are discharged principle describe.
Shown in Fig. 3 a, blast pipe 18 ' central interior is provided with the spray nozzle part 25 that is supported by brace table 26.Said nozzle portion 25 1 sides are connected with tube connector 27.
Shown in Fig. 3 b, it is wide that said nozzle portion 25 shapes form two inlet, the form that the middle part is narrow.Shown in Fig. 3 c, the passage of central portion B is narrower than two A, C.
If have the spray nozzle part 25 of shape as mentioned above, flow into air, two A, the flow velocity of the flow velocity of C and central portion B is with different.
According to the hydrodynamics fundamentum Bernoulli definition of expression rate of flow of fluid and pressure dependence,
ρgh+P+ρV
2/2＝constant
In the above-mentioned formula, V is a flow velocity, and ρ is a density, and g is an acceleration of gravity, and h is the height h on any horizontal plane, and P is the malleation of fluid.
In above-mentioned rule, ρ gh+P is equivalent to the position energy, ρ V
2/ 2 are equivalent to kinergety.The position energy of above-mentioned defined declaration fluid and kinergety sum are stable all the time.According to above-mentioned definition, suppose not have the viscosity abnormal fluid, when the position energy was identical, in the fluid that flows, flow velocity was fast more, and malleation can be low more; Flow velocity is slow more, and malleation can be high more.
That is, the summation of energy does not change, so the minimizing of some energy, the increase that brings other energy speeds up, and will reduce pressure.
At the spray nozzle part 25 of above-mentioned condensed water discharge portion 30, look every field A, B, when the position energy of C was identical, because central portion B is narrow, what the air velocity of flow nozzle portion became wanted fast relatively.Therefore, the air pressure of central portion B will descend to some extent.
If at the central portion B of spray nozzle part, connect an end of tube connector 27, because the pressure of above-mentioned central portion B is lower than the pressure atmospheric pressure of tube connector, will take place to move because of the fluid of pressure differential.
According to the present invention, in an other side of above-mentioned tube connector 27, connect the condensed water of the heat exchange department generation of laundry dryer, it is discharged because of pressure differential.Take care of in drain pan such as the condensed water that heat exchange department obtains, connect tube connector 27 1 ends with above-mentioned drain pan, because air flows, when the reduction of spray nozzle part 25 central portion B pressure took place, condensed water promptly moved to spray nozzle part along tube connector.
By the condensed water that narrow tube connector moves, mobile with the air of spray nozzle part inside together to the outside discharge of spray nozzle part, thus form nebulization.Therefore, condensed water nature is with the small particles form spraying and discharge, in addition with by blast pipe 18 ', to the outside air of discharging of dryer, together carry out the nature oven dry and discharge.
In embodiment as shown in Figure 4, to being supplied to the high temperature air of laundry dryer drying container, what heat is not heater, but heats according to the heat pump of the steam pressure circulatory system.
As shown in Figure 4, cupboard 32 inside are provided with the 1st air flow circuit 40 and the 2nd air flow circuit 42 is provided with, and above-mentioned the 1st air flow circuit is provided with the heat exchange department 51 of giving air by the heat exchange transfer of heat.Above-mentioned heat exchange department 51 is equivalent to condenser in the steam pressure circulatory system.Above-mentioned heat exchange department 51 connects and composes thermodynamic cycle with other heat exchange departments.Above-mentioned heat exchange department comprises evaporimeter 50, compressor 54 and expansion valve 56, comb 58 and condenser 53.
Above-mentioned evaporimeter 50 also can and produce condensed water with air heat exchange, and for above-mentioned condensed water is discharged naturally, above-mentioned the 2nd air flow circuit 42 inside are provided with condensed water discharge portion 30.The detailed structure of condensed water discharge portion 30 and principle are identical with foregoing.
Drive by the motor 38 that is arranged at cupboard inside, fan 60 is rotated, and will take place to flow into by the air of the 1st air flow circuit 40.Leaked-in air heats up through heat exchange department 51, enters drying container (not shown), dries by after the oven dry thing, passes through the 2nd air flow circuit 42 again to the outside discharge of dryer.Air through the 2nd air flow circuit 42 flows, when passing through condensed water discharge portion 30 again, as telling about among Fig. 3 a to 3c, take place in the spray nozzle part because the pressure of change in flow descends, by tube connector, attract the condensed water that produces by evaporimeter 50 again, to the outside discharge of spray nozzle part.
The condensed water of discharging is sprayed and is very little water droplet, forms the nature oven dry, and to the outside discharge of dryer.
As mentioned above, the present invention can discharge the condensed water that takes place at heat exchange department to the dryer outside naturally by simple device.The condensed water of discharging is discharged in spray nozzle part with atomize, and the flash baking clothing; Condensed water mixes the back to the outside discharge of dryer, so can also play the effect of the indoor humidity that improves the dryer outside with the air that blast pipe is discharged.
Condensate removal system of the present invention is not only applicable to laundry dryer, and is all applicable to all devices that produced condensed water by heat exchange.
The effect of invention
According to a kind of laundry dryer, need not store condensed water in addition, and can discharge naturally.Therefore, can remove the inconvenience that consumer wants is regularly discharged condensed water from.In addition, need not be for the pump of discharging condensed water, storage bin etc., the inner space utilization rate of laundry dryer is big, and can form compact structure more.
