Description

A kind of valve body of washing machine drainage valve

Technical field

The utility model relates to a kind of valve mechanism, is in particular a kind of washing machine drainage valve.

Background technology

Existing washing machine is equipped with draining valve in the bottom of aqua storage tank or washtub usually, and this draining valve can be discharged by draining valve the superfluous water that stores in aqua storage tank or the washtub after washing finishes from drainpipe.

As Fig. 4, shown in Figure 5, drain valve structure for the prior art use in washing machine, this draining valve include valve body 1 ', the intake antrum 11 that valve body 1 ' be provided with axis is parallel to each other and staggers ' and drain chamber 12 ', also be provided with axis respectively with intake antrum 11 ', the valve plug chamber 13 of drain chamber 12 ' perpendicular ', the water inlet 111 that intake antrum 11 ' have links to each other with the washing machine aqua storage tank ', the delivery port 121 that drain chamber 12 ' have links to each other with drainpipe ', valve plug chamber 13 ' interior then be provided with spool 14 ', spool 14 ' the be subjected to restriction of spool tractor, usually spool 14 ' the open back extreme position that can reach is as Fig. 4, dotted line 2 ' position shown in Fig. 5, drain chamber 12 ' axis fundamental sum dotted line 2 ' coincidence; When spool 14 ' when opening, intake antrum and drain chamber connect, normally draining of washing machine (arrow is depicted as water (flow) direction), when spool 14 ' closure, intake antrum and drain chamber are isolated, and washing machine stops draining; Wherein, hatching shown in Figure 5 partly is the draining valve of the prior art draining cross section 3 ' schematic diagram at spool 14 ' presented when opening to extreme position.In order further to increase the draining effective cross-section, shorten water discharge time, also have in the prior art and make the draining cross section of circle into ellipse and improve draining valve and open with equidistant drainage efficiency, but, the sectional area raising rate of this technology is still not enough, also can influence the sealing property of the follow-up hose adapter of valve body simultaneously because of elliptical shape, therefore, await to do further improvement.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of can increase drain discharge effectively and obviously shorten the valve body of the washing machine drainage valve of water discharge time at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the valve body of this washing machine drainage valve, axis is parallel to each other and staggers and be provided with on this valve body intake antrum and drain chamber, described intake antrum offers the water inlet that is connected with washing machine aqua storage tank or washtub, described drain chamber offers the delivery port that is connected with washing machine sewer pipe, also have on this valve body axis respectively with described intake antrum, the valve plug chamber that drain chamber is perpendicular, be provided with the spool that the water route that can control described intake antrum and drain chamber connects or isolates in the described valve plug chamber, it is characterized in that: between the greatest limit position of the axis of described drain chamber when the axis of described intake antrum and described spool are opened.

In order to reach drainage effect preferably, increase the draining sectional area effectively and shorten water discharge time, as preferably, the distance of the greatest limit position when the described spool of the journal offset of described drain chamber is opened is 5～10mm.

In order to prevent that water level in aqua storage tank or the washtub is too high and cause water level to overflow, also be provided with the intersect vertical axis of an axis and described drain chamber and the spilling water valve that connects with this draining valve on the described valve body, this spilling water valve can in time be discharged unnecessary water when water level is too high through the valve body of draining valve.

Compared with prior art, advantage of the present utility model is: the position that the Position Design of drain chamber is become close intake antrum, make drain chamber journal offset the greatest limit position of spool when opening, increased the actual draining area of section of drain chamber at delivery port, thereby can make drainage speed effectively, reduce water discharge time and accelerate about 1/3, in the sealing property that does not influence the follow-up hose adapter of valve body, reduce water discharge time, further improve the drainage efficiency of washing machine.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 3, draining valve valve body 1 for present embodiment, include the intake antrum 11 that Open Side Down, drain chamber 12 that opening makes progress and the valve plug chamber 13 of transverse opening on this valve body 1, intake antrum 11 axially and the axially parallel of drain chamber 12 and stagger and establish, axial axial vertical with intake antrum 11, drain chamber 12 respectively in valve plug chamber 13;

Wherein, the water inlet 111 of intake antrum 11 and the aqua storage tank or the washtub of washing machine link to each other, the delivery port 121 of drain chamber 12 and the drainpipe of washing machine are connected, spool 3 by the spool driver drives then is set in the valve plug chamber 13, these spool 3 shutoff are on the path that intake antrum 11 and drain chamber 12 are connected, and spool 3 can make intake antrum 11 and drain chamber 12 be communicated with or isolate along the axial slip in valve plug chamber 13;

When spool 3 during along the axially slippage to the right in valve plug chamber 13 to maximum open position, when being dotted line 2 positions shown in Figure 2, draining valve is in whole open modes, current can flow out (arrow is depicted as water (flow) direction Fig. 2) from the delivery port 121 of drain chamber 12 through the water inlet 111 of intake antrum 11, and then the superfluous water in washing machine aqua storage tank or the washtub is discharged; When spool 3 during along axially the resetting left of valve plug chamber 13, the path between intake antrum 11 and the drain chamber 12 is cut off drain shut valve by spool.

The intake antrum 11 of present embodiment is a L type bend pipe structure, drain chamber 12 is straight tube structure, between the greatest limit position (dotted line 2 positions) that the axis of drain chamber 12 is positioned at the axis of intake antrum 11 and spool 3 when opening, and, the distance of the axis runout dotted line 2 of drain chamber 12 is 5～10mm, at this moment, drain chamber 12 is as shown in Figure 3 structure at the draining cross section at delivery port place 121 3 areas, because the axis of drain chamber 12 is offset left than the drain chamber axis of prior art, the water inlet 111 of the close more intake antrum 11 of the delivery port 121 of drain chamber 12, under the constant prerequisite of the diameter of drain chamber, make the area in draining cross section increase to some extent, drain discharge increases, and water discharge time reduces 1/3rd, drainage efficiency obviously improves, and can satisfy requirement of client better.

In addition, in order to prevent that water level in washing machine aqua storage tank or the washtub is too high and cause water level to overflow, the valve body 1 of present embodiment also includes one and is connected on the drain chamber 12 and water overflow chamber 14 axial and that drain chamber 12 intersects vertically, this spilling water valve 14 and drain chamber 12 connect, when water level was too high, unnecessary water can flow out from drain chamber 12 through water overflow chamber 14 by pipeline.
