Description

Technical Field

[0001] The present invention relates to the technical field of kitchen and bathroom, and more specifically, to a drainage device, a toilet and a flushing method for the toilet. Background Art

[0002] The existing toilet bowl has a poor flushing effect of urinary flushing, and the urine and feces cavity of the toilet bowl cannot be completely flushed. Summary of the invention

[0003] The analysis and research found that in the existing common two-speed jet siphon toilet, the water guide pipe connects the jet pipe and the wash ring pipe, and the water in the water storage cavity flows into the water guide pipe from the drainage port of a two-speed drain valve, and is sprayed out from the jet port at the bottom of the urine and feces cavity through the jet pipe, and is sprayed out from the wash ring flushing hole at the top of the urine and feces cavity through the wash ring pipe. Once the above structure is formed, the distribution ratio of the water discharged from the water guide pipe between the jet port (jet pipe) and the wash ring flushing hole (wash ring pipe) is fixed, and the distribution ratio of water between the jet port and the wash ring flushing hole is basically the same regardless of large-speed flushing (i.e., fecal flushing) or small-speed flushing (i.e., urine flushing).

[0004] For large-speed flushing, the feces it flushes are prone to blockage. Toilets are usually designed so that most of the water is ejected from the bottom jet port to push away dirt and prevent blockage, so most of the water is allocated to the jet port. For small-speed flushing, the urine it flushes does not have a blockage problem. Instead, the urine is prone to splashing everywhere in the urine and feces cavity. At this time, more water should be allocated to the wash ring flushing hole to flush the splashed urine and feces cavity, but this is impossible to achieve because we already know from the above analysis that the water distribution ratio between the jet port and the wash ring flushing hole is the same when the existing toilet is flushed with large and small gears. Moreover, the above-mentioned problem will be more obvious on water-saving toilets. Since water-saving toilets use very little water, high-speed flushing has to use a larger proportion of water for spraying at the jet outlet to prevent blockage. The water consumption of low-speed flushing is originally very small, and it has to use a larger proportion of water for spraying like high-speed flushing. This results in that the water sprayed from the flushing hole of the wash ring is often so little that it can only moisten the urine and feces cavity. Some of them cannot even wash the entire urine and feces cavity, let alone rinse away the splashes on the urine and feces cavity.

[0005] Therefore, technical personnel in this field urgently need to provide a toilet that can reasonably distribute the water output from the jet port and the water output from the wash ring flushing hole in one distribution method when flushing for defecation without increasing the water output requirement, and reasonably distribute the water output from the jet port and the water output from the wash ring flushing hole in another distribution method when flushing for urination, ensuring that the urine and feces cavity can be flushed clean during both flushing for defecation and flushing for urination.

[0006] An embodiment of the present invention provides a drainage device, which is applied to a toilet and can meet the requirements of reasonably distributing water from the jet port and the water from the wash ring flushing hole in one distribution method when flushing for defecation, and reasonably distributing water from the jet port and the water from the wash ring flushing hole in another distribution method when flushing for urine without increasing the flushing volume, thereby ensuring that the urine and feces cavity can be flushed cleanly during both flushing for defecation and flushing for urine.

[0052] like Figures 3 to 5 As shown, the bracket 322, the overflow pipe 321, the first valve cylinder 361 and the second valve cylinder 371 are made into one body, the overflow pipe 321 is located at the rear side of the first valve cylinder 361 and the second valve cylinder 371, and the water inlet at the top of the first valve cylinder 361 is lower than the water inlet at the top of the second valve cylinder 371.

[0053] The installation relationship between the various components on the toilet is as follows:

[0054] like Figures 3 to 5As shown, the first driving key 311 and the second driving key 312 are arranged side by side and can be mounted on the bracket 322 so as to be movable up and down. The first rod body 331 is mounted on the mounting frame 320 through the middle so as to be swingable up and down. One end of the first rod body 331 is located below the first driving key 311 and the second driving key 312 and is matched with the first driving key 311 and the second driving key 312. The first stopper 342 is arranged obliquely below the first driving key 311 and is hingedly mounted on the overflow pipe 321 so as to be swingable up and down. The first convex column 3111 is pressed downward against the upper end of the first stopper 342. The second stopper 352 is arranged obliquely below the second driving key 312 and is hingedly mounted on the overflow pipe 321 so as to be swingable up and down. The second convex column 3121 is pressed downward against the upper end of the second stopper 352. The first valve cover 362 is located below the second valve cover 372. One end of the first valve cover 362 and one end of the second valve cover 372 are both hinged on the overflow pipe 321, so that the first valve cover 362 can be opened and closed on the first valve cylinder 361, and the second valve cover 372 can be opened and closed on the second valve cylinder 371. The upper ends of the first connecting rope 341 and the second connecting rope 351 are correspondingly connected to the two ends of the second rod body 332, and the lower ends of the first connecting rope 341 and the second connecting rope 351 are respectively connected to the other end of the first valve cover 362 and the other end of the second valve cover 372. The first swing rod 343 is hingedly mounted on the first valve cover 362 through the lower end. The two sets of limiting ribs 344 at the lower end of the first swing rod 343 are used to limit the swing stroke of the first swing rod 343. The upper end of the first swing rod 343 corresponds to the lower end of the first stop rod 342. The second swing rod 353 is hingedly mounted on the second valve cover 372 through the lower end thereof, and the two sets of limiting ribs at the lower end of the second swing rod 353 are used to limit the swing stroke of the second swing rod 353. The upper end of the second swing rod 353 corresponds to the lower end of the second stop rod 352. Figures 1 to 5 As shown, the lower end of the first valve cylinder 361 is installed in the injection installation port 121 and is sealed by the injection seal 365. The lower end of the second valve cylinder 371 is installed in the wash ring installation port 122 and is sealed by the wash ring seal 373. The water inlet valve 200 is installed in the water storage chamber 120. The lower part of the overflow pipe 321 is connected to the second valve cylinder 371. The first drive key 311 is used for defecation flushing, and the second drive key 312 is used for urination flushing.

[0055] The action and effect of this toilet:

[0056] like Figure 4As shown, when flushing the stool, the first driving key 311 is pressed, and the first driving key 311 pushes the driving rod 330 and the first stop rod 342 to swing, while the second stop rod 352 does not swing. The second rod body 332 opens the first valve cover 362 and the second valve cover 372 by pulling up the first connecting rope 341 and the second connecting rope 351, and the upper ends of the first swing rod 343 and the second swing rod 353 swing backward under the action of inertia. Since the lower end of the first stop rod 342 swings upward, avoiding the swing stroke of the upper end of the first swing rod 343, the first swing rod 343 swings backward to the maximum position over the lower end of the first stop rod 342, and the first valve cover 362 is opened to the maximum opening angle. Since the second stopper 352 does not swing, the lower end of the second stopper 352 interferes with the swing stroke of the upper end of the second swing rod 353, so the upper end of the second swing rod 353 swings backward to the side of the lower end of the second stopper 352 and cannot swing to the maximum position, and the second valve cover 372 cannot open the cover to the maximum opening angle. At this time, the water in the water storage chamber 120 is discharged from the first valve cylinder 361 and the second valve cylinder 371 at the same time. One way passes through the washing ring pipeline 140 and is sprayed from the washing ring flushing hole 112 to clean the side of the urine and feces chamber 110, and the other way passes through the injection pipeline 130 and is sprayed from the injection port 111, pushing the dirt at the bottom of the urine and feces chamber 110 to be discharged, and allowing the water to quickly fill the siphon pipe 150. After the first driving key 311 is released, under the action of the counterweight structure, the second valve cover 372 first falls back to close the second valve cylinder 371, and the first valve cover 362 falls back to close the first valve cylinder 361. After the second drain valve 370 is closed, the first drain valve 360 ​​continues to drain water, and the jet port 111 continues to spray strongly to prevent blockage. The water level in the water chamber 120 continues to drop, and the first valve cover 362 is partially exposed above the water surface, causing the buoyancy of the first valve cover 362 to decrease. Finally, the first valve cover 362 falls quickly to close the first valve cylinder 361, and the jet port 111 stops discharging water (see Figure 6 and Figure 7 , during the swinging and falling process of the first valve cover 362, the opening angle of the first valve cover 362 gradually decreases, and the first swing rod 343 is at a lower height when it is kept at the maximum swing angle, so the upper end of the first swing rod 343 is lower than the lower end of the first stop rod 342 during the swinging process, and will not be blocked by the lower end of the first stop rod 342. The first swing rod 343 can swing back smoothly, and the first valve cover 362 can be installed on the first valve cylinder 361). That is: a large proportion of water is discharged from the first drain valve 360 ​​through the injection port 111, and a small proportion of water is discharged from the second drain valve 370 through the washing ring flushing hole 112, the urine and feces cavity 110 will not be blocked, and the inner side of the urine and feces cavity 110 can also be rinsed clean.

[0057] like Figure 5As shown, when flushing, the second driving key 312 is pressed, and the second driving key 312 pushes the driving rod 330 and the second stop rod 352 to swing, while the first stop rod 342 does not swing. The driving rod 330 opens the first valve cover 362 and the second valve cover 372 by pulling up the first connecting rope 341 and the second connecting rope 351, and the upper ends of the first swing rod 343 and the second swing rod 353 swing backward under the action of inertia. Since the lower end of the second stop rod 352 swings upward, avoiding the swing stroke of the upper end of the second swing rod 353, the second swing rod 353 swings backward to the maximum position over the lower end of the second stop rod 352, and the second valve cover 372 is opened to the maximum opening angle. Since the first stopper 342 does not swing, the lower end of the first stopper 342 interferes with the swing stroke of the upper end of the first swing rod 343, so the upper end of the first swing rod 343 swings backward to the side of the lower end of the first stopper 342 and cannot swing to the maximum position, and the first valve cover 362 cannot open the cover to the maximum opening angle. At this time, the water in the water storage chamber 120 is discharged from the first valve cylinder 361 and the second valve cylinder 371 at the same time. One way passes through the wash ring pipeline 140 and sprays out from the wash ring flushing hole 112 to clean the side of the urine and feces chamber 110, and the other way passes through the injection pipeline 130 and sprays out from the injection port 111, pushing the dirt at the bottom of the urine and feces chamber 110 to be discharged, and allowing the water to quickly fill the siphon pipe 150. After the second drive key 312 is released, under the action of the counterweight structure, the first valve cover 362 first falls back to close the first valve cylinder 361, and the second valve cover 372 falls back to close the second valve cylinder 371. The siphon pipe 150 gradually forms a siphon, and then the first valve cover 362 falls quickly. After the first drain valve 360 ​​is closed, the jet port 111 stops jetting. The second drain valve 370 continues to drain water, and the wash ring flushing hole 112 continues to discharge water to flush the splashes on the inner side of the urine and feces chamber 110. At the same time, under the action of the siphon, the water at the bottom of the urine and feces chamber 110 is continuously sucked away by the siphon pipe 150. The water level in the water chamber 120 continues to drop, and the second valve cover 372 is partially exposed to the water surface. The buoyancy of the second valve cover 372 decreases, and the second valve cover 372 falls quickly to close the second valve cylinder 371. The second drain valve 370 is closed, and the wash ring flushing hole 112 gradually stops discharging water. That is, a small proportion of water is discharged from the first drain valve 360 ​​through the jet port 111, and a large proportion of water is discharged from the second drain valve 370 through the wash ring flushing hole 112, so that the urine and feces chamber 110 can be better rinsed.

[0058] This toilet has better flushing effects for both urine flushing and stool flushing. Moreover, the water inlet of the first drain valve 360 ​​is lower than the water inlet of the second drain valve 370, so the drainage volume of stool flushing is greater than that of urine flushing, and urine flushing is more water-saving. After flushing is completed, the water inlet valve 200 feeds water into the water chamber 120, and the water level in the water chamber 120 rises to the working state. The first drain valve 360 ​​is a jet drain valve, and the second drain valve 370 is a wash ring drain valve. Water is stored in the water seal water storage section of the jet pipe 130.

[0059] Embodiment 2

[0060] The flushing method of a toilet provided in an embodiment of the present invention comprises: when performing a defecation flush, controlling to increase the drainage volume of a jet drain valve and to reduce the drainage volume of a wash ring drain valve, so as to increase the water output of a jet pipe and to reduce the water output of a wash ring pipe; when performing a urination flush, controlling to reduce the drainage volume of a jet drain valve and to increase the drainage volume of a wash ring drain valve, so as to reduce the water output of a jet pipe and to increase the water output of a wash ring pipe.

[0061] It can be that, when flushing for defecation, the opened wash ring drain valve is closed first, and the opened jet drain valve is closed after a delay, so as to achieve the purpose of increasing the drainage volume of the jet drain valve and reducing the drainage volume of the wash ring drain valve, and the jet drain valve and the wash ring drain valve can be set to be opened at the same time; when flushing for urination, the opened jet drain valve is closed first, and the opened wash ring drain valve is closed after a delay, so as to achieve the purpose of reducing the drainage volume of the jet drain valve and increasing the drainage volume of the wash ring drain valve, and the jet drain valve and the wash ring drain valve can be set to be opened at the same time; or it can be that the wash ring drain valve and the jet drain valve adopt electric control valves, and the above-mentioned flushing method is realized by controlling the control panel. The above can all achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all belong to the protection scope of the present application.

[0062] In an exemplary embodiment, if Figure 4 As shown, when flushing the stool, the first drive key 311 is driven to operate, and the drive rod 330 drives the first drive assembly 340 and the second drive assembly 350 to open the jet drain valve and the wash ring drain valve respectively, and under the action of the first drive assembly 340 and the second drive assembly 350, the jet drain valve lags behind the wash ring drain valve in closing, thereby increasing the drainage volume of the jet drain valve and reducing the drainage volume of the wash ring drain valve.

[0063] For example, Figure 4 As shown, when flushing the stool, the first driving key 311 is pressed, and the first driving key 311 pushes the driving rod 330 and the first stopper 342 to swing, and the driving rod 330 opens the first valve cover 362 and the second valve cover 372 by pulling up the first connecting rope 341 and the second connecting rope 351, and the upper ends of the first swing rod 343 and the second swing rod 353 swing backward under the action of inertia. The lower end of the first stopper 342 swings upward to avoid the swing stroke of the upper end of the first swing rod 343, so the first swing rod 343 swings backward to the maximum position over the lower end of the first stopper 342, and the first valve cover 362 is opened to the maximum opening angle. The second stopper 352 does not swing, and the lower end of the second stopper 352 interferes with the swing stroke of the upper end of the second swing rod 353, so the upper end of the second swing rod 353 swings backward to the side of the lower end of the second stopper 352 and cannot swing to the maximum position, and the second valve cover 372 cannot be opened to the maximum opening angle.

[0064] At this time, the water in the water holding chamber 120 is discharged from the first valve cylinder 361 and the second valve cylinder 371 at the same time. One way passes through the washing ring pipe 140 and is sprayed out from the washing ring flushing hole 112 to clean the side of the urine and feces chamber 110, and the other way passes through the injection pipe 130 and is sprayed out from the injection port 111, pushing the dirt at the bottom of the urine and feces chamber 110 to be discharged, and allowing the water to quickly fill the siphon pipe 150. After the first drive key 311 is released, under the action of the counterweight structure, the second valve cover 372 first falls back to close the second valve cylinder 371, and the first valve cover 362 falls back to close the first valve cylinder 361. After the washing ring drain valve is closed, the injection drain valve continues to drain water, and the injection port 111 continues to spray strongly to prevent blockage. The water level in the water holding chamber 120 continues to drop, and the first valve cover 362 is partially exposed above the water surface, causing the buoyancy of the first valve cover 362 to decrease. Finally, the first valve cover 362 quickly falls to close the first valve cylinder 361, and the injection port 111 stops discharging water (see Figure 6 and Figure 7 , during the swinging and falling process of the first valve cover 362, the opening angle of the first valve cover 362 decreases, and the first swing rod 343 is kept at a lower height when the maximum swing angle is maintained, so the upper end of the first swing rod 343 is lower than the lower end of the first stop rod 342 during the swinging process, and will not be blocked by the lower end of the first stop rod 342. The first swing rod 343 can swing back smoothly, and the first valve cover 362 can be installed on the first valve cylinder 361). That is: a large proportion of water is discharged from the jet drainage valve through the jet port 111, and a small proportion of water is discharged from the washing ring drainage valve through the washing ring flushing hole 112, the urine and feces cavity 110 will not be blocked, and the inner side of the urine and feces cavity 110 can also be cleaned.

[0065] For example, Figure 4 As shown, the inner diameters of the first valve cylinder 361 and the second valve cylinder 371 are the same. When flushing the stool, the drainage volume of the jet drain valve is greater than the drainage volume of the wash ring drain valve.

[0066] In an exemplary embodiment, if Figure 5 As shown, when flushing for urination, the second drive key 312 is driven to operate, and the drive rod 330 drives the first drive assembly 340 and the second drive assembly 350 to open the jet drain valve and the wash ring drain valve respectively, and under the action of the first drive assembly 340 and the second drive assembly 350, the wash ring drain valve lags behind the jet drain valve in closing, thereby increasing the drainage volume of the wash ring drain valve and reducing the drainage volume of the jet drain valve.

[0067] For example, Figure 5As shown, when flushing the urinary bladder, the second driving key 312 is pressed, and the second driving key 312 pushes the driving rod 330 and the second stopper 352 to swing. The driving rod 330 opens the first valve cover 362 and the second valve cover 372 by pulling up the first connecting rope 341 and the second connecting rope 351, and the upper ends of the first swing rod 343 and the second swing rod 353 swing backward under the action of inertia. The lower end of the second stopper 352 swings upward to avoid the swing stroke of the upper end of the second swing rod 353, so the second swing rod 353 swings backward to the maximum position over the lower end of the second stopper 352, and the second valve cover 372 opens to the maximum opening angle. The first stopper 342 does not swing, and the lower end of the first stopper 342 interferes with the swing stroke of the upper end of the first swing rod 343, so the upper end of the first swing rod 343 swings backward to the side of the lower end of the first stopper 342 and cannot swing to the maximum position, and the first valve cover 362 cannot open to the maximum opening angle.

[0068] At this time, if Figure 5 As shown, the water in the water storage chamber 120 is discharged from the first valve cylinder 361 and the second valve cylinder 371 at the same time. One way is sprayed out from the washing ring flushing hole 112 through the washing ring pipe 140 to clean the side of the urine and feces chamber 110, and the other way is sprayed out from the injection port 111 through the injection pipe 130, pushing the dirt at the bottom of the urine and feces chamber 110 to be discharged, and the water quickly fills the siphon pipe 150. After the second driving key 312 is released, under the action of the counterweight structure, the first valve cover 362 falls back to close the first valve cylinder 361 first, and the second valve cover 372 falls back to close the second valve cylinder 371. The siphon pipe 150 gradually forms a siphon, and then the first valve cover 362 falls quickly. After the injection drain valve is closed, the injection port 111 stops spraying. The washing ring drain valve continues to drain water, and the washing ring flushing hole 112 continues to discharge water to flush the splashed dirt on the inner side of the urine and feces chamber 110. At the same time, under the action of the siphon, the water at the bottom of the urine and feces chamber 110 is continuously sucked away by the siphon pipe 150. The water level in the water storage chamber 120 continues to drop, the second valve cover 372 is partially exposed to the water surface, the buoyancy of the second valve cover 372 decreases, the second valve cover 372 quickly drops to close the second valve cylinder 371, the wash ring drain valve is closed, and the wash ring flushing hole 112 gradually stops discharging water. That is, a small proportion of water is discharged from the jet drain valve through the jet port 111, and a large proportion of water is discharged from the wash ring drain valve through the wash ring flushing hole 112, so that the urine and feces chamber 110 can be better rinsed.

[0069] For example, Figure 5 As shown, the inner diameters of the first valve cylinder 361 and the second valve cylinder 371 are the same. When flushing urine, the drainage volume of the wash ring drain valve is greater than the drainage volume of the jet drain valve.
