Description
Technical field
The utility model belongs to the floor air conditioner field, is specifically related to a kind of up and down air conditioner room unit of air outlet that has.
Background technology
The Split floor-type indoor machine of air conditioner of prior art, be mainly a motor wind wheel system is arranged in the bottom, upwards air-supply, then blow out from the top of air conditioner room unit by indoor set heat exchanger and deliver to the room, air outlet is all on the top of air-conditioner, then by wind deflector with the oblique lower guiding of circulated air room lower space, this version has certain effect when air-conditioner freezes, because itself sinks cold air, and people do not need cold air is delivered to the very near position, underfooting of liftoff plate; 1), be because the higher hot-air of temperature moves upward after being sent air outlet but when air conditioner heat-production, the effect of this version performance is just less:, be difficult to wind deflector the oblique lower guiding of hot-air very low position overhead; 2), be because the people to the responsive department of heat perception in foot, as long as foot has warmed up, it is warm that whole body will be felt, so need air conditioner room unit that hot blast is delivered to the very near position of liftoff plate; 3), be if air conditioner room unit by wind deflector with the oblique lower guiding of hot blast room lower space, hot-air can blow to people's face, and the people is felt under the weather, and greatly reduces the comfort of air-conditioner.
Conventional floor type air-conditioner is when heating simultaneously, hot-air floats over the upper strata in room on mainly, is more than 2 meters substantially, and people movable space in the room is mainly below 2 meters, therefore the heat that floats over the upper strata, room on is wasted substantially, has greatly caused the waste of the energy.
Summary of the invention
The purpose of this utility model is in order to overcome above problem, a kind of up and down air conditioner room unit of air-supply is provided, realize highly effective refrigeration, low wind heats, not only can easily hot blast rate be delivered to the bottom space in room, improve the comfortableness of air-conditioner, and improve the utilization rate of heating capacity of air conditioner, thus energy-conserving and environment-protective.
A kind of up and down air conditioner room unit of air-supply, comprise air-conditioner housing, upper volute blower fan and lower spiral case blower fan have been arranged side by side up and down in the housing, the upper volute blower fan is provided with enterprising air port and upper air outlet, lower spiral case blower fan is provided with lower air inlet and lower air outlet, and upper and lower air inlet oppositely is arranged on respectively the sidepiece of upper and lower spiral case blower fan; Upper and lower air inlet connects the housing air-inlet grille, is provided with heat exchanger between air-inlet grille and the upper and lower air inlet; Upper and lower air outlet respectively to the upper and lower air outlet grate of housing extend and connected and composed the air inducing air channel (the air inducing air channel can be that independently the air channel is connected with volute of blower, perhaps, the air inducing air channel and make with volute of blower integral body).When air-conditioner moves, space air enters from the middle air inlet of air conditioner room unit, through indoor set heat exchanger, enter respectively upper volute blower fan and lower spiral case blower fan, then send by upper air inducing air channel and lower air inducing air channel respectively, make the bottom space in room and the effect that middle space reaches fast cooling or heats up.
Described air-inlet grille is arranged on front plate, left side plate or the tergal position of housing.Described air-inlet grille places the medium position (front intaking air at middle part, positive left and right sides air intake or back side intaking air at middle part) of housing.
Described air outlet grate is arranged on upper and lower, left or right position and the combination (front-outlet, upper two side air-outs, lower front-outlet and lower two side air-outs in six air-supplies) thereof of the front plate of housing.
The spiral case of described upper and lower spiral case blower fan be by two independently housing consist of, by being spirally connected or snapping is connected and fixed, two housings and housing are by being spirally connected or snapping is connected and fixed between the two housings.
The spiral case of described upper and lower spiral case blower fan is that integral body is made, and whole spiral case and housing are by being spirally connected or snapping is connected and fixed.
Described heat exchanger be shaped as arc, in line shape or V-arrangement.
User selection starts refrigeration mode: air outlet grate and lower air outlet grate are opened in most selections simultaneously; When the user need to deliver to upper sheaf space with most of cold air, the small part heat is delivered to lower layer space, just increase the rotation speed of fan of upper volute blower fan, reduce the rotation speed of fan of lower spiral case blower fan, make the rotation speed of fan of upper volute blower fan greater than the rotation speed of fan of lower spiral case blower fan, and the rotation speed of fan of lower spiral case blower fan is greater than zero; When the user needs all cold air are all sent from upper air outlet grate, just the rotation speed of fan of upper volute blower fan is transferred to maximum, the rotation speed of fan of lower spiral case blower fan is zero (calm), thus the fan parking of the lower spiral case blower fan of control, and close lower air outlet grate.
User selection starts heating mode: air outlet grate and lower air outlet grate are opened in most selections simultaneously; When the user need to deliver to lower layer space with most of heat, the small part heat is delivered to sheaf space, then increase the rotation speed of fan of lower spiral case blower fan, reduce the rotation speed of fan of upper volute blower fan, make the rotation speed of fan of lower spiral case blower fan greater than the rotation speed of fan of upper volute blower fan, and the rotation speed of fan of upper volute blower fan is greater than zero; When the user needs all heats are all sent from lower air outlet grate, just the rotation speed of fan of lower spiral case blower fan is transferred to maximum, the rotation speed of fan of upper volute blower fan is zero (calm), thus the fan parking of control upper volute blower fan, and air outlet grate is closed in the pass.
The beneficial effects of the utility model are: when air conditioner heat-production, the lower air outlet grate of air conditioner room unit can be delivered to overhead very near space with most of hot-air, what make air-conditioner heats heat mainly at the lower layer space in room, improve rapidly the temperature of room lower layer space, make foot and the shank of human body feel very soon warm, greatly improved the utilization rate of air-conditioner heat, unlike the conventional air-conditioning device, the upper sheaf space that floats over the room on the hot-air has been wasted, and the lower layer space heat of people's activity seldom; When air-conditioner freezes, the upper air outlet grate of air conditioner room unit can be delivered to overhead higher space with most of cold air, and cold air sinks automatically, is the cooling of room lower layer space, the health that cold wind directly can not blowed to the people feels under the weather the people, has improved the comfort of air-conditioner.Solve the shortcoming that conventional air-conditioning exists, improved comfortableness and the capacity usage ratio of air-conditioner, reached the effect of energy-conserving and environment-protective.
