Abstract
The invention relates to an indoor fan of a window-type air conditioner, which comprises a front fan disk, a bottom fan disc, a fan blade, and a fan connecting part. The front fan disc faces a wind inlet side and forms a wind cavity inlet; the bottom fan disc is arranged a certain distance from the front fan disc to form a wind cavity of the indoor fan and can be used as an air register to change the flow direction of air flow flowing into the wind cavity; the fan blade is arranged between and respectively fixed to the front fan disc and the bottom fan disc and forms a wind cavity outlet to radially discharge air entering the wind cavity; the fan connecting part is arranged on the bottom fan disc and connected with the a fan motor and supplies power for the rotation of the indoor fan; and a circular water discharge groove is arranged at the inner side of the outer edge of the bottom fan disc in the wind cavity and shares one circle center with the bottom fan disc. When the air conditioner works in a refrigeration mode, condensed water flows into the water discharge groove and is blocked by the water discharge groove, thereby preventing the condensed water from being discharged from an indoor wind outlet of the air conditioner and improving the comprehensive quality of the air conditioner.

But, there is following not enough point in the aforesaid prior art:
The indoor fan of window air conditioner of the prior art is a centrifugal fan, the running status of indoor fan is aweather to absorb air in the chamber during air-conditioner refrigerating operaton, because the temperature of air conditioner refrigerating evaporimeter is lower, on evaporimeter, can produce condensed water, when passing evaporimeter, flow air partial condensation water can be taken in the indoor fan, indoor fan when rotation condensed water under action of centrifugal force can be thrown out of, and, cause the user that the cognition degree of the quality of air-conditioner is reduced along with air is arranged to indoor from the air outlet of air-conditioner.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rhone that circumferential is set in the peripheral edge inboard on fan chassis, thereby avoid condensed water to be discharged by the air outlet of air-conditioner, guaranteed the indoor fan of the window air conditioner of air-conditioner operate as normal by indoor fan.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The indoor fan of window air conditioner of the present invention comprises: the fan shroud, towards the inlet side and form wind chamber inlet; The fan chassis forms the wind chamber of fan from a distance with the fan shroud, and changes the air flow direction in inflow wind chamber as air register; Fan blade is arranged between fan shroud and the fan chassis, and is fixing respectively with fan shroud and fan chassis, and the chamber outlet of formation wind is radially discharged the air that enters the wind chamber; Fan connecting part is arranged on the fan chassis, is connected with fan electromotor and for indoor fan rotation provides power, and rhone, rhone and the fan chassis concentric of circumferential is set in the peripheral edge inboard on the fan chassis of inside, wind chamber.
The present invention can also adopt following technical measures:
The described cross section that is arranged on the rhone on the fan chassis is a circular arc.
The degree of depth of described rhone is the 1/3-1/2 of fan chassis thickness.

The specific embodiment
It is following that the present invention will be described in detail with reference to drawings and Examples.
Fig. 3 is the structural representation of the indoor fan of window air conditioner of the present invention.
As shown in Figure 3, in the indoor fan of window air conditioner of the present invention, fan shroud 71 is towards the inlet side and form wind chamber inlet, and the internal diameter of shroud is that the size of wind chamber inlet should be more than or equal to the size on fan chassis, to guarantee having enough intakes to enter in the wind chamber when air-conditioner turns round; Fan chassis 72 and fan shroud form the wind chamber of indoor fan from a distance, fan chassis and fan shroud be arranged in parallel, wind chamber inlet on the fan shroud faces the fan chassis, when the indoor fan rotation, the air that enters the wind chamber from wind chamber inlet can directly impact on the fan chassis, this moment, the fan chassis changed the air flow direction that flows into the wind chamber as air register, made the air Radial Flow; Fan blade 73 is arranged between fan shroud and the fan chassis, and is fixing respectively with fan shroud and fan chassis, and forms wind chamber outlet 74, and the air that enters the wind chamber is radially discharged; Fan connecting part 75 is arranged on the fan chassis, is connected with fan electromotor and provides power for indoor fan rotation; The rhone 76 of circumferential is set in the peripheral edge inboard on the fan chassis of inside, wind chamber, and rhone is provided with and fan chassis concentric continuously.Dropping onto in the air-conditioning chassis in order to make condensed water be more prone to conflux in rhone, can be circular arc with the cross section of rhone, makes condensed water easier flowing in rhone.The degree of depth of rhone is 1/2 of a fan chassis thickness, can make rhone dark as far as possible when guaranteeing fan chassis intensity, avoids condensed water to overflow from rhone.The distance of rhone outer ledge and fan chassis edge is 1.5 times of fan chassis thickness, if rhone the position is set too near the center on fan chassis, then excessive area is just left on the fan chassis of rhone periphery, drop on the outer condensed water of rhone circumference equally can under action of centrifugal force, be discharged to air indoor, thereby lost the design sense of blocking condensed water on the fan chassis.
When air-conditioner begins cooling operation, indoor fan begins rotation at a high speed by fan connecting part under the driving of fan electromotor, gas between the fan blade is in the action of centrifugal force current downflow, make the periphery and the exit, wind chamber in wind chamber form normal pressure, and form negative pressure in the inside and the porch, wind chamber in wind chamber, ambient atmos is inhaled in the wind chamber under atmospheric effect, to replenish the gas of discharging, and then be discharged to outside the wind chamber by the centrifugal force that fan blade produces, so continually air is transferred out.
The indoor fan of window air conditioner of the present invention, the rhone of circumferential is set in the peripheral edge inboard on the fan chassis of inside, wind chamber, during the air-conditioner refrigerating operaton, there is partial condensation water to enter in the wind chamber of indoor fan, and condensed water outwards moves on fan chassis, centrifugal action lower edge, when condensed water arrives rhone, can flow into rhone and lived by the rhone interception, centrifugal force just can't continue water is played a supporting role when putting aside abundant water in the rhone, condensed water can flow down along rhone owing to the gravity effect, fall into then be discharged in the chassis of air-conditioner outdoor, thereby avoid making condensed water to discharge from the indoor air outlet of air-conditioner.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention with preferred embodiment openly as above, yet, be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, certainly can utilize the technology contents of announcement to make a little change or modification, become the equivalent embodiment of equivalent variations, be the content that does not break away from technical solution of the present invention in every case, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all belong in the scope of technical solution of the present invention.
