Abstract
The utility model discloses an under pump body of draining pumps, which includes a main body, a water inlet and a water outlet. A gradually deepening stream guidance socket is arranged along the direction of waterflow on the cavity wall of the main body. The ending point of the stream guidance socket is in the deepest position and serves as the water outlet. The utility model overcomes the deficiencies that original draining pumps have small drain flow rate and low drain efficiency which are caused by the pump body structure of original drain pumps. The utility model is applicable to the drain pumps of air conditioners for increasing flow rate of the drain pumps and enhancing the drain efficiency.
Description
Technical field:
The utility model relates to a kind of member that is used for the draining pump on the air conditioner, especially relates to a kind of lower pump body of draining pump.
Background technique:
Air conditioner is when refrigerating operaton, and airborne moisture content is understood condensation and attached on the heat exchanger, is dropped in then in the water pond that is arranged at the heat exchanger below.For the condensed water that accumulates in this water pond is drained, air conditioner all is equipped with draining pump.The main structure of common use in refrigeration system draining pump as shown in Figure 1, this draining pump is made up of motor 10, upper pump casing 20, impeller 30 and lower pump body 40, impeller 30 is located in the pump housing shell that upper pump casing 20 and lower pump body 40 closures form, impeller 30 with pass upper pump casing 20 on through hole motor 10 the axle be connected, and in pump case, rotated freely by the driving of motor 10, the bottom of lower pump body 40 is provided with water intake 41, and the side is provided with water outlet 42.When draining pump is worked, 30 rotations of motor 10 drives impeller, the condensed water that amasss in water pond is inhaled into water intake 41, and since the effect of inertia that impeller 30 drives and in the pump housing on rise, be subjected to centrifugal action from the water outlet 42 of lower pump body 40 sides, to give off the outside at last.
See also the structure plan view of the known lower pump body 40 of Fig. 2 again, lower pump body 40 includes main body 43, water intake 41 and water outlet 42, and this main body 43 has the bowl-shape inner chamber 45 that is surrounded by internal chamber wall 44.As can be seen from Figure, current mainly are eddy flow in inner chamber 45 (seeing shown in the figure arrow A) after entering lower pump body 40 by the water intake 41 of bottom, when current pass through the water outlet 42 of main body 43 sides, because the internal chamber wall 44 at water outlet 42 places is smooth circular-arc, therefore only some current because of action of centrifugal force by flowing out in the water outlet 42, and some current can be taken advantage of a situation and continued eddy flow forward along internal chamber wall 44.Current can not be flowed out from water outlet 42 more, thereby reduced the flow of draining pump, influenced the drainage efficiency of draining pump.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome the defective that drain discharge is little, drainage efficiency is low that original draining pump lower pump body structure causes, and the draining pump that a kind of flow is big, drainage efficiency is high lower pump body is provided.
The utility model has taked following technological scheme to solve its technical problem:
A kind of draining pump lower pump body includes main body, water intake and water outlet, and the internal chamber wall upper edge water (flow) direction of described main body is provided with a gradually dark diversion groove, and the terminating point of this diversion groove is the bosom and is positioned at water outlet.
The terminating point of the diversion groove of draining pump lower pump body described in the utility model forms a step radially at the water outlet place, and is located at the center of water outlet; Rounding off is formed on the bottom of this diversion groove and main body internal chamber wall, and its length is less than 3/4 circumference of main body internal chamber wall.
Compare with the structure of existing draining pump lower pump body, draining pump lower pump body described in the utility model is provided with the gradually dark diversion groove of terminating point at water outlet on the internal chamber wall of its main body, therefore the lower pump body main body internal chamber wall at the water outlet place is smooth circular-arc no longer just, thereby most of current will enter water outlet and flow out the pump housing along diversion groove.The structure of diversion groove has increased the flow of draining pump greatly like this, has improved drainage efficiency.
Description of drawings:
Fig. 1 is the structural representation of draining pump.
Fig. 2 is the plan view of lower pump body shown in Figure 1.
Fig. 3 is a structure plan view of the present utility model.
Embodiment:
Now the utility model is described in further detail with specific embodiment in conjunction with the accompanying drawings.
See also Fig. 3 structural representation of the present utility model, diagram draining pump lower pump body includes main body 3, water intake 1 and water outlet 2.Described main body 3 has bowl-shape inner chamber 5, and this inner chamber 5 encloses structure by internal chamber wall 4 and forms; Water intake 1 is positioned at the lower end of main body 3, and water outlet 2 is located at the side of the inner chamber 5 of main body 3; Be provided with a gradually dark diversion groove 6 in the internal chamber wall 4 upper edge water (flow) directions of main body 3 (see among the figure shown in the arrow A), the length of this diversion groove 6 is changeable, be generally less than 3/4 circumference of internal chamber wall 4, its terminating point is the bosom of groove and is positioned on the water outlet 2, in illustrated embodiment, the terminating point of this diversion groove 6 is positioned at the center of water outlet 2, and forms one along inner chamber 5 step 7 radially at this place.This diversion groove 6 is actually outwards to be extended gradually by internal chamber wall 4 to be deepened and forms, itself and the bottom formation rounding off of internal chamber wall 4, this just make current can take advantage of a situation naturally mobile along diversion groove 6.
When draining pump is worked, enter the current of lower pump body inner chamber 5 because action of centrifugal force is close to internal chamber wall 4 along the direction eddy flow shown in the arrow A among the figure, flow to water outlet 2 places along diversion groove 6 then, because stopping of step 7 radially, most of current are with regard to entering water outlet 2 outside the efflux pump.Therefore, draining pump lower pump body described in the utility model can guide most of current just to discharge by water outlet 2 in eddy flow circulation first, has improved drainage efficiency greatly, has increased the flow of draining pump.
