As shown in Figure 2, the first open and close valve V1, the second open and close valve V2, the 3rd open and close valve V3 and the 4th open and close valve V4 are opened and closed regularly and the switching time by control device C control.Because the second open and close valve V2, the 3rd open and close valve V3 and the 4th open and close valve V4 are the open and close valves that utilizes air, therefore do not need very big pressure, the open and close valve miniaturization more that it can Billy's water, and can carry out on-off action with very little strength.
In above Western-style flush-type closet, the getter device 200 of toilet drainage channel 5 is made of ejector 30, first connecting pipe 110, one way valve 111, negative pressure pressure accumulation case 70, second connecting pipe 120, the 3rd open and close valve V3, the 3rd connecting pipe 130, the 4th open and close valve V4, inlet box 80, suction pipe 90 and control device C.Cleaning water feeder is made of aqueduct 10, filter for installation 11, constant flow rate valve 12, the first open and close valve V1, vacuum circuit breaker 13, ejector 30, nozzle 50, water tank 20, the second open and close valve V2, efferent duct 40, first connecting pipe 110, second connecting pipe 120, the 3rd open and close valve V3 and control device C.
Below, according to structure shown in Figure 1, the action of the closet bowl cleaning device S of the getter device 200 that is assembled with embodiment 1 is described.
When clean [non-]
In Fig. 3, during non-clean before the t1 time point, the first open and close valve V1, the second open and close valve V2, the 3rd open and close valve V3 and the 4th open and close valve V4 all close.Under this state, in water tank 20, store clean water.Barrier films 83 in the inlet box 80 are connected on the downside internal face in the inlet box 80.
[bedpan is cleaned stroke negative pressure pressure accumulation stroke]
After closet used, at the t1 of Fig. 3 time point, the user operated by the clean switch that subtend control device C sends the Closet bowl cleaning commencing signal, thereby opens the first open and close valve V1 by control device C.
Thus, the clean water that flows in aqueduct 10 flows in the swirling chamber 29 by ejector 30.Clean water flow in the ejector 30, and ejector 30 is by the air in first connecting pipe 110 and the one way valve 111 negative suction pressure accumulation casees 70, and the air that is inhaled into is in clean water flows into swirling chamber 29.Circle round in swirling chamber 29 owing to clean water, therefore cleaning air in the water can be separated well and be accumulated in the top that flows into chamber 25.Thus, in negative pressure pressure accumulation case 70, accumulate negative pressure gradually, by inhaled air from negative pressure pressure accumulation case 70 water surface that flows into chamber 25 is correspondingly descended gradually simultaneously.
In addition, the clean water of supplying with by aqueduct 10 and be stored in the water tank 20 and, be supplied to labial surface 3 by efferent duct 40 corresponding to the clean water of amount of air drawn from negative pressure pressure accumulation case 70.The clean water that is supplied to labial surface 3 flows down while circling round along the inner face of bedpan 2, thereby forms the stream that circles round in bedpan 2.By this stream that circles round, dirt is focused on the central authorities of bedpan 2.And by this stream that circles round, toilet paper is decomposed and mixes with clean water, and is dispersed in the clean water.
[suction stroke]
At the t2 of Fig. 3 time point, the 4th open and close valve V4 is opened by control device C.Thus, the negative pressure in the negative pressure pressure accumulation case 70 is passed in first Room 81 of inlet box 80 by first connecting pipe 110, the 3rd connecting pipe 130 and the 4th open and close valve V4, becomes negative pressure thereby make in first Room 81.And, clean water owing in ejector 30, supply with continuously, therefore also be inhaled into by the air in the ejector Room 81 30, the first.Thus, negative pressure when being opened at first in the negative pressure pressure accumulation case 70 by the 4th open and close valve V4, and the barrier film 83 in the inlet box 80 is sharply promoted, afterwards because negative pressure pressure accumulation case 70 sucks finishes, therefore only make barrier films 83 in the inlet box 80 rise to the upper inside walls face that is connected to inlet box 80 lentamente by ejector 30 till.
When the air in the toilet drainage channel 5 being drawn into second Room 82 by inlet box 80, water level in the bedpan 2, become fully high owing to clean the clean water of supplying with in the stroke to bedpan 2 at bedpan, it also becomes greatly abundant with water-head between the 4a of highest order portion of water seal portion 4.Therefore, clean water in the bedpan 2 sucks by the potential energy of the clean water that produces because of this water-head and the air in the toilet drainage channel 5, and clean water is flow in the toilet drainage channel 5 quickly, be the state of cleaning the water full water in the toilet drainage channel 5 and produce powerful siphonage thereby make in advance.Therefore, just can form the discharge current in advance with seldom clean water.In addition, the toilet drainage channel 5 interior full water states that produce siphonage are meant, be not only limited to and in toilet drainage channel 5, be the state of cleaning the complete full water of water, also refer to keep-up pressure balance and produce the state that draining is flowed, be also included within the remaining situations that air is arranged in the toilet drainage channel 5 in the upstream of toilet drainage channel 5 side and downstream one side.
At this moment, owing to the formed stream that circles round in bedpan 2 is concentrated in the dirt of bedpan 2 central authorities, will be by siphonage and along with the clean water of discharging to toilet drainage channel 5, and be discharged to reliably in the toilet drainage channel 5.
In addition, downstream one side of toilet drainage channel 5 is blocked by delay portion 6, and toilet drainage channel 5 becomes confined space between water seal portion 4 and delay portion 6.Therefore, can from toilet drainage channel 5, suck air in certain amount reliably, thereby can stably produce siphonage.
In addition, be divided into first Room 81 and second Room 82 by barrier film 83 in the inlet box 80, owing to only have second Room 82 to be communicated with toilet drainage channel 5, so the clean water that can prevent to contain dirt reliably and the air that contains foul smell etc. enter a side of negative pressure pressure accumulation case 70 and ejector 30.
[clean water and increase stroke]
At the t3 of Fig. 3 time point, the water level of bedpan 2 will drop near the height of the 2a of lowest order portion at bedpan 2 rear portions, in this moment, opens the 3rd open and close valve V3 by control device C, and closes the 4th open and close valve V4.
At this moment, clean water owing to still supply with in ejector 30, therefore outside a large amount of air will flow in the swirling chamber 29 by the 3rd open and close valve V3, second connecting pipe 120 and first connecting pipe 110.Therefore, flow into the clean water in the chamber 25, because of a large amount of air that flow into are expressed in the labial surface 3 by delivery chamber 26 and efferent duct 40.The water level that flows in the chamber 25 is descended sharp significantly.
Air flow into the toilet drainage channel 5 and finishes before the siphonage from bedpan 2, promptly, the water level bedpan 2 in is lower than before the 2a of lowest order portion at bedpan 2 rear portions, will increase to the clean water of labial surface 3 supplies.Just, owing to the clean water of supplying with from labial surface 3, be by the clean water of aqueduct 10 supplies and the clean water sum that is stored in water tank 20, so the water yield of the clean water of supplying with to bedpan 2 in the time per unit will increase.Thereby, the not broken envelope of water seal portion 4, the clean water in the bedpan 2 is proceeded to circle round, and siphonage also will continue.And circling round in the bedpan 2 flowed also can grow.And the flow of water of cleaning water also increases.Therefore, the dirt that residues in the bedpan 2 is extruded and is discharged in the toilet drainage channel 5, and, the light dirt in the clean water that swims in the bedpan 2 is discharged in the toilet drainage channel 5.
[instroke]
At the t4 of Fig. 3 time point, increase stroke and be supplied to clean water in the bedpan 2 by cleaning water, also in bedpan 2, circle round the broken envelope of water seal portion 4.That is, the discharge current that produce because of siphonage are continuing.At this t4 time point, close the first open and close valve V1 by control device C, and open the 4th open and close valve V4.By this mode, because first Room 81 of inlet box 80 is by the 4th open and close valve V4, the 3rd connecting pipe 130, first connecting pipe 110, second connecting pipe 120 and the 3rd open and close valve V3 and external communications, therefore will become atmospheric pressure in first Room 81, thereby barrier film 83 is descended.Thereby air is discharged in the toilet drainage channel 5 from second Room 82, thereby the air in the toilet drainage channel 5 is increased.Therefore, can't will be maintained full water state in the toilet drainage channel 5 by cleaning water, thereby siphonage finishes.In addition, can't will be maintained full water state in the toilet drainage channel 5 by cleaning water, even also comprise residually in toilet drainage channel 5 having under the air state, upstream one side of toilet drainage channel 5 and downstream one side keep-up pressure balance and can't keep the state that produces draining stream.In this case, because therefore the broken envelope of water seal portion 4 does not produce brokenly the sound that seals.
[covering the water stroke]
At the t5 of Fig. 3 time point, open the first open and close valve V1 and the second open and close valve V2 by control device C, and close the 4th open and close valve V4.By this mode, clean water when ejector 30 sucks air from the outside and can flow in the swirling chamber 29.The air of cleaning in the water is separated in swirling chamber 29 well, and is released to the outside by atmospheric air port 23, the second open and close valve V2.Therefore, the clean water in the water tank 20 is accumulated and is cleaned the preceding predetermined water level of beginning.And siphonage finishes fully, cleans water and is supplied to labial surface 3 from delivery chamber 26 by efferent duct 40, has the water seal portion of predetermined water level and covers water thereby form in bedpan 2.
[atmosphere opening stroke]
At the t6 of Fig. 3 time point, close the first open and close valve V1 by control device C, and open the 4th open and close valve V4.By this mode, first Room 81 of inlet box 80 once more by the 4th open and close valve V4, the 3rd connecting pipe 130, first connecting pipe 110, second connecting pipe 120 and the 3rd open and close valve V3 and and external communications, thereby till the downside internal face that barrier film 83 is dropped to be connected to inlet box 80.Its result is that barrier film 83 is returned to be cleaned on the preceding assigned position, thereby can stably carry out cleaning of next time.Afterwards, at the t7 of Figure 13 time point, close the second open and close valve V2, the 3rd open and close valve V3 and the 4th open and close valve V4 by control device C.
Therefore, in the getter device 200 of the toilet drainage channel 5 of embodiment 1, can be well and undisturbedly carry out Closet bowl cleaning.
The Western-style flush-type closet of embodiment 2 has the structure identical with embodiment 1, and as shown in Figure 4, only the action of closet bowl cleaning device S is different with the Western-style flush-type closet of embodiment 1.
Difference to the action of closet bowl cleaning device S describes.
As shown in Figure 4, increasing the t4 time point of time point t3 ' after the process stipulated time that stroke finishes, close the first open and close valve V1 by control device C, and open the 4th open and close valve V4 from cleaning water.By this mode, because first Room 81 of inlet box 80 is by the 4th open and close valve V4, the 3rd connecting pipe 130, first connecting pipe 110, second connecting pipe 120 and the 3rd open and close valve V3 and external communications, therefore will become atmospheric pressure in first Room 81, thereby barrier film 83 is descended.Increase stroke at clean water and finish and passed through the t4 time point of stipulated time, increase stroke and be supplied to clean water in the bedpan 2 by cleaning water, thereby the clean water yields in the bedpan 2 are reduced also because of siphonage is discharged in the toilet drainage channel 5.Therefore, when air when second Room 82 is pressed in the toilet drainage channel 5, can make at once because of the formed discharge current of siphonage interrupt, and can be immediately and siphonage is finished.And, in this case, because therefore the broken envelope of water seal portion 4 does not produce brokenly the sound that seals.Identical because of other action with embodiment 1, thereby omit its detailed description.
Therefore, the getter device 200 of the toilet drainage channel 5 of embodiment 2 is also identical with embodiment 1, can bring into play action effect of the present invention.
Though more than describe the present invention according to embodiment 1,2, the present invention is not subjected to the restriction of described embodiment 1,2, can carry out suitable change in the scope that does not break away from its aim.
