Technical field
The present invention relates to the Split floor-type indoor machine of air conditioner technical field, more specifically, relate to the improvement of Split floor-type indoor machine of air conditioner.
Background technology
Split-type air conditioner: formed by indoor set and off-premises station, be installed in respectively indoor and outdoors, the middle air regulator that couples together by pipeline and electric wire.It is the corresponding outer machine of interior machine, and it is relative with package AC plant, and package AC plant is all-in-one, without dividing of inside and outside machine; That split-type air conditioner indoor set has is wall-hanging, cabinet-type, ceiling mounting type, embedded.Detachable air conditioner is divided into indoor units and outdoor unit two parts to air-conditioner exactly, the larger compressor of noise ratio, aerofoil fan etc., is placed in the off-premises station; The indoor indispensable parts such as electric control circuit parts and indoor heat exchanger are installed in the indoor units; We claim this air-conditioner that is made of indoor set and off-premises station to be called detachable air conditioner.
Existing indoor unit of floor type air conditioner air outlet structure, its air outlet structure all is the mentality of designing with reference to traditional cross flow fan, the size of air outlet is fixed, indoor set such as the disclosed a kind of cabinet air conditioner of Chinese patent (Granted publication CN201416958Y), comprise housing, be installed in the evaporimeter in the housing, front induced draft plate, rear induced draft plate and air-supply wind wheel, the upper back of its middle shell is provided with return air inlet, the front upper part both sides of housing are respectively equipped with air outlet, it is characterized in that described air-supply wind wheel be about 2 tubular wine wheels, vertically be installed in the air channel of air outlet inboard respectively.The disclosed floor air conditioner indoor machine of Chinese patent (Granted publication CN202040903U) and for example, comprise the upper frame that is arranged on the body, the air channel that heat exchanger, tubular wine wheel assembly is set in the upper frame and holds heat exchanger, tubular wine wheel assembly, the left side of upper frame, right side and rear side are respectively arranged with air inlet, this air inlet comprises left air inlet, right air inlet and rear air inlet, and left air inlet, right air inlet and rear air inlet connecting place are respectively arranged with left back air inlet and right back air inlet; The front side of upper frame is provided with the air outlet that is connected with air inlet, and air outlet is left air outlet and right air outlet.
But its air outlet structure of above-mentioned patent is the mentality of designing with reference to traditional cross flow fan, and the size of air outlet increases gradually.And this air outlet structure that increases gradually very easily produces suddenly big or suddenly small abnormal sound, and air-conditioning condenser dirty after, this abnormal sound can further strengthen, and to the harassing and wrecking that the user produces, has affected user's effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Split floor-type indoor machine of air conditioner air outlet structure, and it can eliminate the abnormal sound of air channel structure, reduces level of noise.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of Split floor-type indoor machine of air conditioner, comprise housing, be located at the heat exchanger in the housing, dividing plate, left axial-flow fan and right axial-flow fan, left axial-flow fan and right axial-flow fan are located at respectively the dividing plate both sides, wherein, also be respectively equipped with left air-out air channel and right air-out air channel on described left axial-flow fan and the right axial-flow fan, left air-out air channel comprises left air channel cavity, comprise left the first air outlet in the cavity of left air channel, left the second air outlet and left the 3rd air outlet, left the first air outlet size is greater than left the second air outlet, and left the first air outlet size is less than left the 3rd air outlet;
Right air-out air channel comprises right air channel cavity, comprises right the first air outlet, right the second air outlet and right the 3rd air outlet in the cavity of right air channel, and right the first air outlet size is greater than right the second air outlet, and right the first air outlet size is less than right the 3rd air outlet.
During use, the rotation of left axial-flow fan and right axial-flow fan and cause Air Flow after air is entered by air inlet, is carried out exchange heat through heat exchanger, behind then flow through left axial-flow fan and the right axial-flow fan, discharges through left air-out air channel and right air-out air channel.Because left the first air outlet size is greater than left the second air outlet, left the first air outlet size is less than left the 3rd air outlet, right the first air outlet size is greater than right the second air outlet, right the first air outlet size is less than right the 3rd air outlet, namely left air channel cavity, right air channel cavity all are that size diminishes gradually, then the structure that increases gradually of size, this structure can be eliminated the abnormal sound in the air channel, reduces level of noise; In addition, at (screen pack, heat exchanger dirty situation under) in the situation that duct resistance increases, air-conditioning can not produce abnormal sound.
Further, described left the first air outlet cross-sectional distance is D1, left the second air outlet cross-sectional distance is D2, left the 3rd air outlet cross-sectional distance is D3, right the first air outlet cross-sectional distance is D4, and right the second air outlet cross-sectional distance is D5, and right the 3rd air outlet cross-sectional distance is D6, D2＜D1＜D3, D5＜D4＜D6.Left air channel cavity and right air channel cavity are similar columnar structure, but similar columnar middle part cross-sectional distance is less than the cross-sectional distance at two ends, and the cross-sectional distance of the right side first air outlet of a left side first air outlet of close left axial-flow fan, close right axial-flow fan is less than a left side the 3rd air outlet of far-end, the cross-sectional distance of right the 3rd air outlet.
Further, described D1 is 1.3～2.0 times of D2, and D4 is 1.3～2.0 times of D5.When D1 is 1.3～2.0 times of D2, D4 is 1.3～2.0 times of D5, and through test, its level of noise is lower than the air outlet structure that increases gradually, therefore, can eliminate the abnormal sound in left air-out air channel and right air-out air channel, has improved the comfort that the user uses.
Compared with prior art, beneficial effect is: left the first air outlet size is greater than left the second air outlet, left the first air outlet size is less than left the 3rd air outlet, and right the first air outlet size is greater than right the second air outlet, and right the first air outlet size is less than right the 3rd air outlet; Can eliminate the abnormal sound of air channel structure, reduce level of noise, in addition, at (screen pack, heat exchanger dirty situation under) in the situation that duct resistance increases, air-conditioning can not produce abnormal sound.
