For solving the problems of the technologies described above, the utility model adopts technical scheme to be:
A kind of For Drain Valve of Washing Machine, comprise valve body, valve gap, valve body is provided with external screw thread for the installation mouth of pipe of valve gap is installed, suitable with the internal thread that valve gap ring wall is provided with, the outer wall of the described installation mouth of pipe is also provided with at least one positioning bar, the ring wall of described valve gap extends and is provided with at least one spacer along axis direction, and described positioning bar is the direction revolution toward thread looseness for spacer described in backstop.
On the axis direction of the described installation mouth of pipe, the width of described positioning bar and described spacer overlapping is less than the pitch of screw thread.
At described mounting pipe mouth in the radial direction, described positioning bar is higher than the outside wall surface of described spacer.
Described positioning bar upper surface is inclined-plane, and upper surface direction is from low to high consistent with the installation direction that described valve gap screws in described valve body.
Described spacer internal face is made as inclined-plane, consistent with the installation direction that described valve gap screws in described valve body by being thinned to thick bevel direction, and after described valve gap and described valve body are installed, both are adjacent for the thick end of described spacer and described positioning bar high-end.
The utility model also relates to a kind of washing machine, comprises outer barrel, interior bucket, control system, drainage system, and drainage system is used the For Drain Valve of Washing Machine described in above-mentioned any one.
Adopt after technique scheme, the utility model compared with prior art has following beneficial effect:
The draining valve of washing machine has increased the anti-loose structure being comprised of positioning bar and spacer, simple in structure, and good operability effectively prevents that draining valve is in long-term use procedure, and the loosening drainage that occurs appears in valve gap.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of For Drain Valve of Washing Machine in prior art;
Fig. 2 is the schematic diagram of the utility model For Drain Valve of Washing Machine;
Fig. 3 is the schematic diagram of valve body in Fig. 2;
Fig. 4 is the schematic diagram of valve gap in Fig. 2.
Number in the figure: 1. valve body, 2. valve gap, 3. positioning bar, 31. positioning bar upper surfaces, 4. spacer, 41. spacer internal faces, 5. valve body external screw thread, 6. valve gap internal thread, 7. installs the mouth of pipe.
The specific embodiment
Shown in Figure 2, be the schematic diagram of For Drain Valve of Washing Machine described in the utility model, this is state after valve body and valve gap are installed.Fig. 3, Fig. 4 are respectively the schematic perspective view of valve body and valve gap.
Draining valve comprises valve body 1, valve gap 2 etc.On valve body, there is the water inlet pipe mouth that connects outer barrel of washing machine, washing machine overflow pipe, there is the effluent pipe mouth that connects washing machine sewer pipe, also has the inner installation mouth of pipe that valve plug, valve spring, valve pipe, extension spring are installed, the installation mouth of pipe of valve body is provided with valve body external screw thread 5, mouth of pipe end is installed and will installs valve gap 2, valve gap 2 ring walls have valve gap internal thread 6, and valve gap 2 is threaded connection and is fixed as one with valve body 1.
Valve body 1 described in the utility model is also provided with positioning bar 3 at the installation mouth of pipe 7 places, the ring wall of valve gap 2 in axial direction also extends and is provided with a spacer 4, positioning bar 3 and spacer 4 suitable contact when valve body 1 is installed with valve gap 2, be after valve body 1 is tightened with valve gap 2, spacer 4 is stuck in the place, the place ahead of positioning bar 3, along the installation screw-in direction of valve gap 2, spacer 4 slightly deformation slips over positioning bar 3.Like this, if the vibration being threaded due to washing machine of valve gap 2 and valve body 1 may produce when loosening, muscle 3 backstops that are positioned of the spacer 4 on valve gap 2, prevent that valve gap 2 is loosening effectively.
For guaranteeing the moving reliability of positioning and locking, along the radial direction that the mouth of pipe is installed, positioning bar 3 peaks are higher than the height of spacer 4, effectively backstop spacer 4, positioning bar 3 is than the high 0.3mm-1.5mm of spacer 4 outer wall, and the width of positioning bar 3 and spacer 4 overlappings is less than the pitch of screw thread.
For the ease of installing, on the one hand, positioning bar 3 upper surfaces are inclined-plane, and positioning bar 3 upper surfaces 31 direction is from low to high consistent with the installation direction that described valve gap 2 screws in described valve body 1.Positioning bar 3 is from starting from low to high, to that is to say with spacer 4 contact points, when valve gap 2 screws in valve body 1, and the low side of the positioning bar 3 that spacer 2 first touches, valve gap 2 can successfully screw in like this.Optimally, the design of positioning bar 3 is that upper surface initiating terminal is lower, that is to say, has one section of lower stroke, and spacer 4 does not contact with positioning bar 3.
On the other hand, the internal face of spacer 4 is made as inclined-plane, and spacer 4 internal faces 41 are from starting by being thinned to thickly with positioning bar 3 contact points, and being beneficial to valve gap 2 can successfully screw in.
For guaranteeing the intensity of positioning bar 3, the thickness range of positioning bar 3 is 2mm-5mm.
The height of the positioning bar relating in the utility model, specific explanations is to be the positioning bar size along the radial direction of the mouth of pipe is installed; The thick of positioning bar is along the positioning bar size that the axial direction of the mouth of pipe is installed.
The utility model also relates to a kind of washing machine, comprises outer barrel, interior bucket, control system, drainage system, and drainage system is used above-mentioned For Drain Valve of Washing Machine.By the improvement to drain valve structure, increase anti-loose structure, avoid the loosening washing machine drainage causing of valve gap, by positioning bar, spacer are provided with to ramp structure, during installation, easily operate.
Above-described embodiment is only that preferred embodiment of the present utility model is described; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; the various changes and modifications that in this area, professional and technical personnel makes the technical solution of the utility model, all belong to protection domain of the present utility model.
