The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
Referring to Fig. 1-Fig. 9; The embodiment of a kind of roller washing machine drainage arrangement of the utility model; Comprise: the urceolus 2 that is used to be filled with water; Be formed at the water discharge outlet 2-1 of urceolus 2 bottoms, be installed in urceolus water discharge outlet 2-1 and make washings flow to the pump hose 7 of draining pump 5, be installed in the energy-conservation ball 6 that pump hose 7 and urceolus 2 links play non-return effect; Be installed in pump hose 7 water sides and be used to produce specified pressure and make washings flow to the Pressure water discharging pump 5 of outside, be installed in draining pump 5 water sides and make washings flow to the internal drainage pipe 3 of collecting box 1; Be installed in the collecting box 1 that is used to hold washings on the shell, and be installed in collecting box 1 water side make washings flow to the outside outer drainpipe 10.
Above-mentioned energy-conservation ball 6 places urceolus water discharge outlet 2-1 below to be slightly larger than in the chamber of its volume, and the aperture that cavity bottom is communicated with pump hose 7 is slightly less than the external diameter of energy-conservation ball 6, and the external diameter of energy-conservation ball 6 is greater than the bore of urceolus water discharge outlet 2-1.
Passage 1-1 is set on collecting box 1, on urceolus 2, passage is set, have the two ends of a breather pipe 8 to connect the passage 1-1 of collecting box 1 and the passage of urceolus 2 respectively, the check valve ball 9 of non-return effect together is installed at the passage 1-1 place of collecting box 1.
Near passage 1-1 position one horizontal channel 12 that communicates with collecting box inside is set in the above-mentioned collecting box 1; Said check valve ball 9 is arranged in the described horizontal channel 12, and horizontal channel 12 1 ends are communicated with collecting box passage 1-1, other end setting and the collecting box 1 interior opening that is communicated with; Horizontal channel 12 openings are provided with a catch 11 outward; The effect of catch 11 is to stop that 12 openings roll out check valve ball 9 from the horizontal channel, still, do not seal the opening of horizontal channel 12.The diameter of said check valve ball 9 is greater than the aperture of collecting box passage 1-1.
The embodiment of a kind of roller washing machine of the utility model comprises casing, urceolus 2, inner core driving mechanism and drainage arrangement.The structure of its drainage arrangement is identical with the structure of the foregoing description, so repeat no more.
After the washing machine water filling for the first time, according to U type pipe principle, liquid level is identical with internal drainage pipe 3 interior liquid levels in the urceolus 2; Washing machine is when draining; Draining pump 5 is taken the water in the pump hose away, makes and forms negative pressure in the pump hose 7, and this moment, urceolus 2 interior liquid pushed up energy-conservation ball 6 down; Form path, reach the draining purpose.Draining pump 5 delivery ports are malleation in the collecting box 1 through arriving collecting box 1 at this moment, and check valve ball 9 blocks breather pipe 8 places, and liquid is through discharging washing machine, shown in Fig. 3-5.
After liquid had been arranged in the urceolus 2, draining pump 5 quit work, because draining pump 5 self operation principle and installation site, liquid can not all be discharged washing machine in the collecting box 1.After draining pump 5 quit work, the water surface fell after rise rapidly to pump hose 7 in the collecting box 1, because the energy-conservation ball of buoyancy 6 with urceolus water discharge outlet 2-1 sealing, is prevented that sewage backflow is in urceolus 2 by jack-up.Owing to be provided with collecting box 1, the liquid level of internal drainage pipe 3 is higher than water level far away, according to U type pipe principle, newly advances the interior residual water of washings and drainage arrangement and isolates fully, avoids cross pollution and is heated simultaneously, causes waste.When washing machine was in washing or oven-dried condition, check valve ball 9 was in open mode, guaranteed that urceolus 2 inside are in communication with the outside, and the pressure in the balance urceolus 2 also can be discharged to the steam that oven dry produces the machine outside, improves drying efficiency, shown in Fig. 6-8.
As shown in Figure 9, when washing machine is in hull-borne, the water side immersed in liquid level of outer drainpipe 10; After washing machine quits work; Water level falls after rise to make and produces negative pressure in the collecting box 1 in the collecting box 1, and check valve ball 9 is in channel status, avoids occurring siphonage; Residual water in the collecting box 1 is siphoned away, cause failure of apparatus.
Wherein, the effect of energy-conservation ball 6 is: in the washing process, energy-conservation ball 6 can prevent that sealing and washing agent run off, and also can avoid the water in the drainage arrangement to be heated simultaneously, causes waste; During rinsing, can prevent that initiate water from mixing with the interior sewage of drainage arrangement, improves wash effect; Avoid sewage backflow during draining.
The effect of collecting box 1 is: after having arranged water fully, draining pump 5 quits work, and aqueous reflux to draining pump 5 and pump hose 7 in the collecting box 1 with energy-conservation ball jack-up, are brought into play the effect of energy-conservation ball.
The effect of breather pipe 8: 1, during draining, when the draining pipe end occurring and submerging the water surface, prevent to form siphon effect, cause energy-conservation ball 6 can't realize its function; 2, when water inlet washing, spaces are in communication with the outside in the urceolus 2, prevent the water inlet water of choking; When 3, drying steam is discharged to the washing machine outside; 4, prevent the siphonage that cause specific occurs when causing water into, avoid occurring the situation of draining while intaking.
The effect of check valve ball 9: during draining pump 5 drainings, collecting box 1 is blocked with passage 1-1, prevent that sewage backflow is to urceolus 2; When draining pump 5 quits work, keep urceolus 2 to be in communication with the outside, the effect of performance breather pipe 8.The above parts must use its effect of competence exertion jointly.
Below only be some specific embodiments of the utility model; Above-mentioned concrete structure can not be interpreted as it is the restriction to the utility model; In fact; The specific embodiment of the utility model has a variety of, and every insubstantial modifications of in the utility model design, it being made all falls within the protection domain of the utility model.
