Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
The operation principle of the cabinet air-conditioner of the present invention and prior art are identical, it is referred to prior art, so no longer describing, the present invention is that heat exchanger is different with the structure of drip tray from the difference of prior art, it is detailed below, part same as the prior art continues to use the label of prior art, and sees the figure of prior art.
Such as Fig. 5, shown in 6, the cabinet type air conditioner indoor set of the present invention, including: constitute the body 50 of outward appearance, it is disposed in the interior the indoor heat converter within body 50 of machine, drip tray, indoor blower 150, indoor heat converter is made up of top half heat exchanger 1 and the latter half heat exchanger 2, the fin density of top half heat exchanger 1 is closeer than the fin density of the latter half heat exchanger 2, drip tray is by the first half drip tray 4 being positioned at bottom top half heat exchanger 1 and is positioned at the lower half drip tray 6 bottom the latter half heat exchanger 2 and constitutes, condensing water tube 3 it is provided with between first half drip tray 4 and lower half drip tray 6.
The size of described first half drip tray 4 is bigger than the floor projection tilting the top half heat exchanger 1 installed.First half drip tray 4 is bar structure.The grid shape slightness hole 5 of first half drip tray 4 exceeds the bottom surface of first half drip tray 4.It is positioned at the bottom surface of the first half drip tray 4 bottom top half heat exchanger 1 and there is no grid shape slightness hole 5.The effect of grid shape slightness hole 5 is to allow the blowing air over of indoor blower 150.
Described top half heat exchanger 1 is consistent with the angle of inclination of the latter half heat exchanger 2.Described top half heat exchanger 1 is thicker than the thickness of the latter half heat exchanger 2.Described drip tray is plastic material.
The course of action of the present invention is as follows as constructed as above:
First, during operation of air conditioner, room air by the left and right side of body 50 or above downside enter the inside of body 50, after carrying out cooling/heating or purifying, by before body 50, left and right or the upper front output towards body 50.
Below, the suction process for room air is described as follows:
Air-conditioning carrying out freezing/heating operating time, as shown in Figure 1, left side sucks wind guide vane and drives motor 93a, start as left side suction inlet open mode, left side is made to suck the open left surface air suction inlet 51 of wind guide vane 93, it is suction inlet open mode that right side suck wind guide vane to drive motor 103a to start, and makes right side suck the open right flank air suction inlet 52 of wind guide vane 103.
Front, left side delivery outlet door 77 is inserted in before upper panel 72 between central authorities and front cover 85, open front, left side air-out 54.
Above right side delivery outlet door 78 is inserted in before upper panel 72 between central authorities and front cover 85, open front, left side air-out 54.
Delivery outlet door motor 86a makes air-out above start above is open mode, makes open air-out 56 above of delivery outlet door 86 above.
When air-supply motor 151 starts in such a state, room air by left surface air suction inlet 51 and right flank air suction inlet 52 and above air suction inlet 53 be drawn into the inside of body 50.
By left surface air suction inlet 51 be drawn into inside room air flow through left side filter 94 time, the foreign body that dust equal-volume within Qing Chuing is bigger, and remove, when the air entered by right flank air suction inlet 52 flows through right side filter 104, the foreign body that volume is bigger.
When the room air sucked by above air suction inlet 53 flows through air cleaner 11,12,13, the foreign body such as dust out, remove trickle dust, when flowing through nanofilter, remove the order particles in air and antibacterial.
When mobile air on the upside of fan guard 155 flows through heat exchanger 1,2, carry out heat exchange with cold-producing medium, cooled or heated.
A part in the cooled or room air of heating is flowed to the front, top of body 50 by air-out 56 above, major part air by front, left side air-out 54 and above right hand side air delivery outlet 55 to the flowing of the front of body 50.That is, indoor apparatus of air conditioner left and right sides before body 50, delivers to front by cold air or steam, provides cold air or steam rapidly thus can to the user in indoor set front.
Meanwhile, in the middle of the supply of above-mentioned cold air or steam, when left side wind guide vane starts with motor 87a, adjusted by the wind direction of the air of front, left side delivery outlet 54 output in the lateral direction by left and right output wind guide vane 87 or changed；After right side wind guide vane starts with motor 88a, by the wind direction of the above air of right side delivery outlet 54 output under the effect of right side output wind guide vane 88, adjust in the lateral direction or change.
When air-conditioning is cleaned operating, left side wind guide vane drives motor 93a to start as left side suction inlet closed mode, make left side suck wind guide vane 93 and close left surface air suction inlet 51, and right flank wind guide vane drives motor 103a startup to be right side suction inlet closed mode, make right side suck wind guide vane 103 and close right flank suction inlet 52.
When air supply motor starts, room air flows into the inside of body 50 by above air suction inlet 53.
When the room air sucked by above air suction inlet 53 flows through air cleaner 11,12,13, the foreign body such as dust out, remove trickle dust, when flowing through nanofilter, remove the order particles in air and antibacterial.
The room air purified through above-mentioned process is exported on the upside of fan guard 155 by orifice plate 156 and fan guard 155.
By the air of output on the upside of fan guard 155, when flowing through heat exchanger 160, do not carry out heat exchange and directly pass through, afterwards by air-out 56 above to the concentration output of the front, top of body 50.
Air-conditioning is when operating stops, left side sucks wind guide vane and drives motor 93a to be driven to left side suction inlet closed mode, make left side suck wind guide vane 93 and close left surface air suction inlet 51, it is closed mode that right side wind guide vane driving motor 103a starts, and makes right side suck wind guide vane 103 and closes right flank air suction inlet 52.
The motor 81 of door drive mechanism 80 carry out with air-conditioning air cleaner operating time start identically, make front, left side delivery outlet door 77 close front, left side air-out 54, make before right side delivery outlet door 78 close above right hand side air delivery outlet 55.
Meanwhile, above delivery outlet motor for door 86a start as air-out closed mode above, make delivery outlet door 86 above close air-out 56 above.
When mobile air on the upside of fan guard 155 flows through heat exchanger 1,2, upper and lower two pieces of heat exchangers 1,2 use different fin density, and top half resistance is relatively big, and the latter half resistance is less, plays the effect of balance heat exchanger wind speed profile.First half drip tray 4 is grating structure, forming part air drag, makes more air discharge from the latter half, further equilibrium heat exchanger wind speed profile.The condensed water of top half heat exchanger directly from condensing water tube 3 pipeline is arranged, alleviates the condensed water problem of the latter half heat exchanger after first half drip tray 4 is collected.The condensate temperature of first half drip tray 4 flowing is relatively low, and air themperature can be made after air heat exchange to reduce, and improves complete machine efficiency.
In sum, present disclosure is not limited in the above embodiments, and the knowledgeable people in same area can propose other embodiment within technological guidance's thought of the present invention easily, but within this embodiment is included in the scope of the present invention.
