Abstract
The utility model provides an air suction type automobile air conditioner drain pipe which comprises an automobile air conditioner body and an evaporation fan. A drain pipe opening of the automobile air conditioner body is connected with a water accumulating ball through a drain pipe body, a balancing pipe is arranged on the connecting portion of the drain pipe body and the water accumulating ball through a tee joint, and the other end of the balancing pipe is fixed to the outside of the evaporation fan. By means of the connection function of the balancing pipe, the pressure on the top of the water accumulating ball is lower than the pressure on the top of the drain pipe body, so that accumulated water can flow out conveniently. The air suction type automobile air conditioner drain pipe can prevent the situation that too much accumulated water is in an HVAC assembly when an automobile goes up a long slope or goes down the long slope, and avoid the situations that due to too much accumulated water, the accumulated water enters the fan, damages the fan and is blown to faces of passengers. In the development and design process of an automobile air conditioner, the air suction type automobile air conditioner drain pipe can be used for reducing faults in use for customers, reducing the risk of occurrence of the faults and reducing maintenance cost.
Description
Technical field
The utility model relates to air conditioning for automobiles parts, specifically air draught type air conditioning for automobiles drainpipe.
Background technology
Air draught type air conditioning for automobiles drainage system generally adopts at present increases ponding ball, relies on the hydraulic pressure of institute's ponding in ponding ball to make up because of air-breathing the caused negative pressure of evaporation fan, and this structure exists following defect: when negative pressure is larger, ponding height is high; During ponding ball poor sealing, when the long-time descending of vehicle or upward slope, drainpipe lost efficacy, and cause cannot draining, thereby more even causes in evaporation tank condensed water too much to gather making that air-conditioning lost efficacy, corrupted.Therefore, in the urgent need to existing air draught type air conditioning for automobiles drain structure is changed.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art, proposes air draught type air conditioning for automobiles drainpipe.
For this reason, the technical solution of the utility model is, air draught type air conditioning for automobiles drainpipe, comprise air conditioning for automobiles body, evaporation fan, the drain pipe port of air conditioning for automobiles body is connected with ponding ball by drainpipe, it is characterized in that: the junction at drainpipe and ponding ball is provided with equalizer line by a threeway, and the other end of equalizer line is fixed on outside evaporation fan.
Beneficial effect:
The utility model is provided with equalizer line in the junction of existing air draught type air conditioning for automobiles drainpipe and ponding ball by a threeway, and the other end of equalizer line is fixed on outside evaporation fan, from the nearest position of evaporation fan.By equalizer line, the minimum negative pressure of evaporation fan is caused to ponding ball place, make ponding ball place pressure lower than the force value of drainpipe root.Make simultaneously the draining of air draught type air conditioning for automobiles more smooth, avoid air-conditioning to blow water, reduce risk that air-conditioning lost efficacy, reduce fault that client in use occurs, reduce the risk and the maintenance cost that break down.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is equalizer line, the 2nd, ponding ball, the 3rd, and drainpipe, the 4th, evaporation fan, the 5th, air conditioning for automobiles body, the 6th, threeway, A are that top, the C of drain pipe port, B ponding ball is outside evaporation fan.
The specific embodiment
The utility model as shown in Figure 1.
Air draught type air conditioning for automobiles drainpipe, comprise air conditioning for automobiles body 5, evaporation fan 4, the drain pipe port A of air conditioning for automobiles body 5 is connected with ponding ball 2 by drainpipe 3, junction at drainpipe 3 and ponding ball 2 is provided with equalizer line 1 by a threeway 6, and the other end of equalizer line 1 is fixed on the outer C of evaporation fan.
Wherein the top B of ponding ball is the junction of drainpipe 3 and ponding ball 2.
The pressure P b that the utility model orders the top B of ponding ball by equalizer line 1 equals the pressure P c that near the outer C of the evaporation fan of evaporation fan 4 is ordered, Pb is less than the pressure Pa that drain pipe port A is ordered, formation pressure reduction is | Pa-Pb|, makes condensed water in HVAC cause the top B of ponding ball.Namely the other end of equalizer line 1 is more approaching better apart from the center of evaporation fan 4, from the more approaching position of negative pressure minimum.
Claims (1)
1. air draught type air conditioning for automobiles drainpipe, comprise air conditioning for automobiles body, evaporation fan, the drain pipe port of air conditioning for automobiles body is connected with ponding ball by drainpipe, it is characterized in that: the junction at drainpipe and ponding ball is provided with equalizer line by a threeway, and the other end of equalizer line is fixed on outside evaporation fan.
