Description
Technical field
The present invention relates to a kind of air-conditioner, particularly a kind of indoor machine of air-conditioner.
Background technology
Existing Split Type Domestic Air indoor set as hanging air conditioner or console mode cabinet-type air conditioner air-conditioner, mainly comprises wind wheel and motor and an air outlet, no matter is refrigeration or heats, all from this air outlet air-supply.During the air-conditioner refrigeration, cold air sinks to lower space from upper space; During air conditioner heat-production, hot gas is to rise to upper space from lower space.
When air-conditioner has only an air outlet, and the position of this air outlet is when the top in room, and superposed hot gas is difficult to move to the bottom.Yet human body is to the more sensitive position of temperature, as pin and leg, but in the activity of the bottom in room, therefore, when the air-conditioner of this structure during at heating mode, is difficult to allow the people feel the warm of room, and the utilization rate of heat is lower, causes energy waste; Simultaneously, hot gas can blow to people's face, can make the people feel to feel bad, and has reduced the comfortableness of air-conditioner.
Small-sized mobile air-conditioner is also arranged on the market, can the room than low spatial in realize sending the hot blast function, but, this mobile air-conditioner air output is little and distance is near, heating capacity and refrigerating capacity are all less, can only the local temperature that improves or reduce the room, can not make that the room is whole to heat up or cooling, comfortableness when therefore mobile air conditioner uses is relatively poor, is not suitable for using than large space.
At present, the air-conditioner of air-out is up and down also arranged, as shown in Figure 1, a cover blower fan and a motor respectively installed in these air conditioner room unit top and bottom, in the middle of heat exchanger is placed on, and a shared air channel, because the cavity in this air channel is bigger, needing blower fan to produce bigger negative pressure could suck the air channel with gas; Utilize result that CFD software carries out emulation to the air channel of this structure as shown in Figure 2, as can be seen from the figure, the air quantity that is positioned at the horizontal centre position in air channel of negative pressuren zone and vertical centre position is all less, and wind field distributes very inhomogeneous; Simultaneously, the operate power of motor will increase, need the more energy during complete machine operation, and during the air channel of shared this structure, the negative pressure that is positioned at the blower fan generation of upper and lower end will influence each other, and causes the intake of the upper and lower end of heat exchanger to differ bigger, and the utilization rate of heat exchanger is lower, cause the complete machine energy consumption big, the operating cost height.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple and reasonable, flexible operation, resistance is little, heat exchange efficiency is high, energy consumption is low indoor machine of air-conditioner, to overcome weak point of the prior art.
A kind of indoor machine of air-conditioner by this purpose design, comprise the last air outlet that is arranged on the body, following air outlet and air inlet, first wind wheel, first motor, first spiral case and last wind deflector are arranged on the top of body, second wind wheel, second motor, second spiral case and following wind deflector are arranged on the bottom of body, heat exchanger is arranged between first spiral case and second spiral case, last wind deflector is arranged in the air outlet, following wind deflector is arranged on down in the air outlet, the rear side that is positioned at heat exchanger in the body is provided with and is communicated with total air channel of going up air outlet and following air outlet simultaneously, its architectural feature is to be provided with the inside wind deflector that this total air channel is divided into upper air duct and lower air duct in total air channel, this inside wind deflector comprises the dividing plate that the middle part is outstanding, and first guide surface and second guide surface that are positioned at the dividing plate both sides, wherein, upper air duct communicates with last air outlet, and lower air duct communicates with following air outlet.
Described first guide surface is parabola face or streamline surface.
Described second guide surface is parabola face or streamline surface.
The end and the heat exchanger of described dividing plate join.
Described air inlet is positioned at the front or the side of heat exchanger.
The present invention is by being provided with the inside wind deflector that this total air channel is divided into upper air duct and lower air duct in total air channel, utilize first guide surface of inner wind deflector and the flow resistance that second guide surface reduces the indoor air flow that enters indoor set, improve the heat exchange efficiency of heat exchanger, and reduce running noises; And, should total air channel be divided into upper air duct and lower air duct after, first wind wheel and second wind wheel can work alone and be independent of each other; Make also that simultaneously the air intake of the both sides up and down of heat exchanger or the left and right sides is more even, improve the operating efficiency of indoor machine of air-conditioner, cut down the consumption of energy.
That the present invention has is simple and reasonable, flexible operation, resistance is little, heat exchange efficiency is high, characteristic of low energy consumption.
