Abstract
The utility model relates to a bend used for inlet exhaust line connection of an indoor air exchanger. The bend is composed of two bent hard pipes, and the two parts are movably connected. One part can rotate 360 degree relative to the other part. One part positioned in an air conditioner indoor unit is connected with an outdoor air outlet of the air exchanger and is motionless, and the other part positioned outside the indoor machine is connected with an outdoor air inlet pipe. The pipelines of the air exchanger can be installed without opening the indoor unit casing. The indoor unit can adapt the direction change of the pipelines by rotating part of bends positioned outside the indoor unit when the direction of the air exchanger pipelines changes, while the partial bends in the indoor unit are fixed and motionless, so the position change of the air outlet can not be influenced.
Description
Technical field
The utility model relates to a kind of pipeline connecting bend, the elbow that especially a kind of intake and exhaust pipeline that is used for indoor air exchanger connects.
Background technique
The air circulation system of air conditioner is by the blower fan that is arranged in the indoor set indoor air to be sucked, and sends back to indoor behind over-heat-exchanger again.In order to save the energy, generally when using air-conditioning, all the room door and window to be closed, therefore cause the indoor air dirt.For solving the air quality of air-conditioned room, indoor and outdoor air should be exchanged, promptly discharge indoor vitiated air, the inspiration outdoor fresh air is so indoor air exchanger occurred.The working principle of ventilator generally all is to introduce outdoor air by suction tude, discharges indoor air by outlet pipe.Advanced at present ventilator, be not limited only to outdoor fresh air is introduced indoor, also consider the position of the outdoor air air outlet of introduction, outdoor air directly is discharged to indoor apparatus of air conditioner air inlet place, can improve the scavenging efficiency of ventilator so on the one hand, air-conditioning is preferentially freezed and blow out just from the outdoor fresh air that enters; The ventilator that has even consider the suction port place that indoor air discharge port is arranged on air conditioner outdoor machine, can increase exhaust efficiency so on the one hand, can increase the air output of outdoor unit axial fan on the other hand, improve the condensation effect of condenser, improve efficiency of air conditioner.But, all relate to the connection of air inlet-outlet pipe and move towards problem no matter be that a kind of ventilator.Especially the ventilator air outlet is arranged at indoor set suction port place, the indoor set shell need be opened, can bring difficulty to installment work thus.And, can be installed on indoor or outdoors because the mounting type of ventilator is flexible, can install with the air-conditioning one and also can install separately, so the trend of its pipeline also is changeable.But this just changeable trend has been brought problem in the reality: or because of turning extruding makes pipe deformation or breaks, influence ventilation effect, or bring the inconvenience of installing because of pipe moves towards change.In addition, the trend of ventilator pipeline or position change often cause the change of position, ventilator air outlet.The indoor and outdoor air air outlet of ventilator is arranged on the air inlet place of air-conditioning indoor and outdoor machine, the position of air outlet has taken into full account the air flow field of the radiating effect of indoor machine evaporation and indoor machine fan and is definite, the change of position must cause the variation of air flow field, and then influence the vaporizer radiating effect, therefore the position of air outlet is in case determine just should not change, but the mounting type of ventilator is flexible, moving towards of its pipeline is changeable, the change of pipeline trend often causes the position change of air outlet, this with the position of air outlet in case definite just should not the change formed contradiction.This contradiction does not have effective solution as yet at present.
Summary of the invention
The purpose of this utility model is to overcome the inconvenience on the existing pipeline jointing construction, when the ventilator relief opening is installed in indoor set intake grill place, need not open the indoor set shell, and the position of the outdoor air air outlet of ventilator can not changed because of the change of pipeline trend.
For addressing the above problem, the utility model has designed a kind of multidirectional elbow, and the two ends of elbow can connect gas pipeline, and elbow is made up of the hard pipe of two bendings, flexibly connects between two-part, and part another part is relatively done 360 degree rotations.Elbow one end has the bayonet socket that is connected with the ventilator pipeline, and this end is positioned at indoor apparatus of air conditioner inside, connects ventilator outdoor air steam outlet pipe, maintains static; The other end is positioned at the indoor set outside, junction chamber outer air suction tude.When the ventilator suction tude is installed, need only the elbow end connection that suction tude is located on the indoor set outside, need not open the indoor set housing; When the ventilator pipeline moved towards to change, rotation was positioned at the part elbow of indoor set outside, can adapt to the variation of pipeline direction, and the part elbow in the indoor set maintains static, thereby can not influence the change in location of air outlet.
The utility model has overcome the inconvenience on the existing pipeline jointing construction, when the ventilator relief opening is installed in indoor set intake grill place, need not open the indoor set shell, and the position of the outdoor air air outlet of ventilator can not changed because of the change of pipeline trend.
Description of drawings

Fig. 2 is a structural representation of forming one section bend pipe of elbow.
Embodiment
Fig. 1 is an elbow structure schematic representation of the present utility model.As shown in Figure 1 and Figure 2, elbow 1 is made up of two rigid elbow, and an end of one of them bend pipe is provided with bayonet socket 2, on the outer wall of the other end screw thread 3 ' is arranged; On the one end inwall of another bend pipe screw thread is arranged, also can establish screw thread 3 on the outer wall of the other end.Two bend pipes flexibly connect by screw thread 3 ' and form, and a bend pipe can another be done 360 degree rotations relatively.Elbow 1 one ends that above-mentioned two bend pipes are formed by connecting have the bayonet socket 2 that is connected with the ventilator pipeline, and after elbow was installed on the indoor set housing, this end was positioned at housing, and the outdoor air steam outlet pipe by bayonet socket 2 connection ventilators maintains static; The elbow the other end has screw thread 3, is positioned at outside the indoor set housing, connects the outdoor air suction tude of ventilator by screw thread 3.The outdoor air suction tude is connected with elbow 1 along indoor set one side.When the ventilator suction tude is installed,, need not open the indoor set housing as long as the screw thread 3 that suction tude is located on the elbow end of indoor set outside connects; When ventilator changed the mounting point, the outdoor air suction tude might need to be connected with elbow from opposite side, and this moment is as long as be positioned at elbow in the outer partial rotation of housing to the appropriate location.
Equally,, also such bend pipe can be installed on outdoor shell, to guarantee the invariant position of ventilator relief opening if the relief opening of ventilator is arranged on the intake grill place of air conditioner outdoor machine.
