Abstract
The invention relates to a fan air-out grille of a dehumidifying machine, which is a spiral structure, arranged on the air outlet of the shell of the dehumidifying machine and is opposite to the fan. The vortex center of the spiral grille is arranged on the central axis of the fan and the motor of the fan. The vortex direction of the spiral air-out grille is consistent with the direction of an air flow blown out by the fan, thus being capable of eliminating the noise generated when the air flow impacts the grille.
Description
Technical field
The present invention relates to dehumidifier, particularly relate to the air outlet grate of dehumidifier.
Background technology
In general, dehumidifier be drawn into indoor malaria in the dehumidifier body after, by changing into than dry air by the dehumidifying of the heat exchanger of internal flow cold-producing medium and being expelled back into indoor device again.
In the dehumidifier, cold-producing medium circulates in the evaporimeter of compressor, heat exchanger and condenser and throttle expansion valve and carries out liquid state and gaseous state conversion, thus the removal moisture drying that realizes entering humid air in the dehumidifier.
The cold-producing medium of low-temp low-pressure evaporates in evaporimeter, and evaporator temperature descends and absorbs heat in the surrounding air, makes around the evaporimeter condensate moisture contained in the humid air and form water droplet at evaporator surface to fall, and reduces airborne humidity; Then, gaseous refrigerant enters the gaseous refrigerant that compressor compresses becomes HTHP from evaporimeter, enters in the condenser decrease temperature and pressure and release heat in the air towards periphery again; Come out liquid refrigerant through throttling expansion once more after the decrease temperature and pressure from condenser, enter in the evaporimeter evaporation and circulate.
Be provided with fan and fan electromotor in the dehumidifier housing, air inlet and air outlet are arranged on the casing, air-inlet grille and air outlet grate are set respectively at air inlet and air outlet.Under the effect of fan, indoor malaria enters in the dehumidifier by air inlet, after removal moisture drying, is flow back to indoor by air outlet.
Fig. 1 shows the internal structure schematic diagram of a kind of dehumidifier of prior art.As shown in Figure 1,
Be provided with evaporimeter 3, condenser 4, compressor 8 and fan electromotor 5 and fan 6 in the dehumidifier casing 1, air inlet on the casing 1 and air outlet are provided with air-inlet grille 2 and air outlet grate 7 respectively.Under the effect of fan 6, indoor malaria enters dehumidifier by air-inlet grille 2 and passes from the evaporimeter 3 coolant conduits outside, the evaporative cooling of evaporimeter 3 inner refrigerants makes the outside humid air contained humidity condensation of passing and forms water droplets on evaporimeter 3 surfaces, and the water droplet that falls enters the dust-collecting bucket 9 of evaporimeter 3 bottoms.Reduce the air of moisture and cooling through evaporimeter 3, pass from the condenser 4 coolant conduits outside again, discharge through passing on the casing 1 air outlet grate 7 after the heat exchanges with condenser 4.Under the style of fan 6, indoor humid air constantly enters in the dehumidifier by the air-inlet grille 2 of air inlet, after removal moisture drying, flows back to indoor through passing through fan by the air outlet grate 7 of air outlet successively.
The fan of the dehumidifier of above-mentioned prior art adopts centrifugal fan or aerofoil fan, and the flow direction of air-flow becomes spirality behind passing through fan, and the air-flow that rotation advances can impact the cross grid of air outlet and send noise.The air outlet grate of air outlet produces the quality of influence of noise dehumidifier.
Summary of the invention
Exist the gas shock grid to produce the problem of noise at the cross air outlet grate of the dehumidifier of above-mentioned prior art, the screw type air outlet grate that release of the present invention is consistent with airflow direction is to eliminate the noise that the gas shock grid produces.
Air outlet grate of dehumidifier involved in the present invention is a spiral-shaped structure, is arranged on the air outlet of dehumidifier casing and relative with fan, and the vortex center of screw type grid is positioned on the central axis of fan and fan electromotor.The swirl direction of screw type air outlet grate is consistent with the airflow direction that fan blows out, and can eliminate the noise that the gas shock grid produces.

The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present invention is further specified.
Fig. 2 is the structural representation of dehumidifier involved in the present invention, and part identical with Fig. 1 among Fig. 2 adopts same tag.As shown in Figure 2, be provided with evaporimeter 3, condenser 4, compressor 8 and fan electromotor 5 and fan 6 in the dehumidifier casing 1 involved in the present invention, air inlet on the casing 1 and air outlet are provided with air-inlet grille 2 and air outlet grate 10 respectively.Under the effect of fan 6, indoor malaria enters dehumidifier by air-inlet grille 2 and passes from the evaporimeter 3 coolant conduits outside, the evaporative cooling of evaporimeter 3 inner refrigerants makes the outside humid air contained humidity condensation of passing and forms water droplets on evaporimeter 3 surfaces, and the water droplet that falls enters the dust-collecting bucket 9 of evaporimeter 3 bottoms.Reduce the air of moisture and cooling through evaporimeter 3, pass from the condenser 4 coolant conduits outside again, discharge through passing on the casing 1 air outlet grate 10 after the heat exchanges with condenser 4.Under the style of fan 6, indoor humid air constantly enters in the dehumidifier by the air-inlet grille 2 of air inlet, after removal moisture drying, flows back to indoor through passing through fan 6 by the air outlet grate 10 of air outlet successively.
Claims (2)
