Abstract
The utility model relates to an air-conditioning indoor unit, which comprises a machine casing, an air duct system, a multi-folding type heat exchanger and a fan. An air inlet is arranged on the front of the machine casing, the multi-folding type heat exchanger comprises a front folding part close to the front of the machine casing and a rear folding part close to the back of the machine casing, and the multi-folding type heat exchanger and the fan are vertically installed in the air duct system in the machine casing. The air-conditioning indoor unit is characterized in that flow blocking strips capable of enabling airflows to be evenly distributed are arranged on the rear folding part of the heat exchanger. By adding the flow blocking strips on the rear folding part of the multi-folding type heat exchanger against an air inlet, the airflows are forced not to concentrate and distributed at places with small airflows, thereby enabling the airflows in the air duct to be evenly distributed, not only obviously improving heat exchanging efficiency of the heat exchanger, but also ensuring that the multi-folding type heat exchanger can express rated capacity and energy efficiency when the air inlet is arranged in the front, being reasonable in design, simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of indoor apparatus of air conditioner, belongs to the improvement technology of indoor apparatus of air conditioner.
Background technology
At present, the heat exchanger of commercially available split wall-hanging air conditioner indoor unit generally all is multi-bended structure, and the air inlet of indoor set generally all is arranged on the top of indoor set, and the air-flow in the air channel distributes evenly basic and can make the heat exchanger sufficient heat exchange; Based on some actual demand; Need be arranged on the front to the air inlet of indoor set, so the rear portion of multi-bended heat exchanger air inlet dorsad, the air-flow that therefore air inlet gets into from the front can accumulate in indivedual positions at the rear portion of many folding heat exchangers; Make other position throughput very little even negative pressure occurs; Cause the air-flow skewness of the heat exchanger of flowing through, the heat exchanger heat exchange is insufficient, has reduced the ability and the efficiency of air-conditioner.
Summary of the invention
The purpose of the utility model is to consider the problems referred to above and provides a kind of ducting system air-flow that can effectively improve to distribute and to make the fully indoor apparatus of air conditioner of heat exchange of heat exchanger.
The technical scheme of the utility model is: a kind of indoor apparatus of air conditioner; Comprise casing, ducting system, multi-bended heat exchanger and blower fan; Wherein air inlet is opened on the front of casing; Multi-bended heat exchanger comprises near the preceding folding part of casing front and back folding part near the casing back side, and on multi-bended heat exchanger and the blower fan in the ducting system of lower device in casing, the back folding part that it is characterized in that said heat exchanger is provided with and makes the equally distributed choked flow bar of air-flow.
Said choked flow bar comprises first flap, second flap and installing plate; Wherein first flap links to each other with second flap and constitutes the rectangular structure of wealthy " V " shape; Its angle is 90 °～140 °; Installing plate is positioned at the two ends and perpendicular the linking to each other of first flap, offers at least one installing hole on the installing plate.
The length of said choked flow bar is corresponding with the lateral length of heat exchanger, and the two ends installing plate of choked flow bar is fixed on through screw on the end plate of both sides, back folding part of heat exchanger.
Said choked flow bar is the metal sheet punch forming.
The utility model is employed in the structure that installs the choked flow bar on the back folding part of the multi-bended heat exchanger of air inlet dorsad additional; Force air-flow not assemble and be diverted to the little place of throughput; Thereby the air-flow in the air channel is distributed uniformly; Not only obviously improved the heat exchange efficiency of heat exchanger, guaranteed that also multi-bended heat exchanger can give play to specified ability and efficiency when air inlet is arranged on the front, reasonable in design, simple in structure, with low cost.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; The utility model indoor apparatus of air conditioner; Comprise casing 5, ducting system 1, multi-bended heat exchanger 2 and blower fan 3, wherein air inlet 6 is opened on the front 51 of casing, and multi-bended heat exchanger 2 comprises near preceding folding part of casing front 51 21 and back folding part 22 near the casing back side 52; In the ducting system 1 of lower device in casing 5, the back folding part 22 of heat exchanger 2 is provided with and makes the equally distributed choked flow bar 4 of air-flow on multi-bended heat exchanger 2 and the blower fan 3.
Like Fig. 2,3,4, shown in 5; Said choked flow bar 4 comprises first flap 41, second flap 42 and installing plate 43; Wherein first flap 41 links to each other with second flap 42 and constitutes the rectangular structure of wealthy " V " shape; Its angle is 90 °～140 °, and installing plate 43 is positioned at the two ends and perpendicular the linking to each other of first flap 41, offers at least one installing hole 44 on the installing plate 43.In the present embodiment, angle is preferably 100 °.
The length of said choked flow bar 4 is corresponding with the lateral length of heat exchanger 2, and the two ends installing plate 43 of choked flow bar 4 is fixed on through screw on the end plate of both sides, back folding part of heat exchanger 2.Said choked flow bar 4 is the metal sheet punch forming.
